This study evaluated the accuracy and feasibility of TCI system for sufentanil at high concentrations in Chinese surgical patients. Methods Twelve low risk adult patients undergoing elective surgery under general anesthesia were included in this study. Sufentanil was administered with a specific TCI system incorporating the population pharmacokinetic data of sufentanil previously reported, using a target effect-site concentration of sufentanil 4 or 6 ng/ml. Sufentanil TCI duration was 30 minutes. Frequent arterial blood samples were taken during and up to 24 hours after sufentanil TCI for determination of plasma sufentanil concentrations by liquid chromatography-mass spectrometry/mass spectrometry. The changes of circulatory system function during the procedure, recovery profile and adverse effects were recorded. Measured plasma sufentanil concentrations were compared with the values predicted by the TCI system. The bias （median performance error, MDPE）, precision （median absolute performance error, MDAPE） and wobble （variability of performance error） of the sufentanil TCI system were determined. Results All patients had stable cardiovascular variables during induction and maintenance of anesthesia. Time to eye opening and extubation were （5.6±1.7） minutes when TCI set to 4 ng/ml and （7.2±2.3） minutes when set to 6 ng/ml. There was no episode of agitation, muscle rigidity or intraoperative awareness. The bias （MDPE）, precision （MDAPE） and wobble of the sufentanil TCI system were -3.7%, 18.9% and 19.6% respectively during TCI, and the MDPE, MDAPE and wobble were -29.1%, 31.7% and 15.0% respectively after TCI （up to 8 hours）. Conclusions The TCI system programmed for sufentanil at 4 or 6 ng/ml was considered acceptable for clinical use in low risk Chinese surgical patients. But the relatively larger MDPE and MDAPE after TCI suggest improvements of the Dharmacokinetic model are needed.展开更多

METHODS: Medline, Embase, trial registries, conference proceedings and article reference lists were searched to identify randomised, controlled trials of continuous wound infusion of local anaesthetic agents following colorectal surgery. The primary outcomes were opioid consumption, pain visual analogue scores (VASs), return to bowel function and length of hospital stay. Weighted mean difference were calculated for continuous outcomes. RESULTS: Five trials containing 542 laparotomy wounds were eligible for inclusion. There was a sig- nificant decrease in post-operative pain VAS at rest on day 3 (weighted mean difference: -0.43; 95% CI: -0.81 to -0.04; P = 0.03) but not on post-operative day 1 and 2. Local anaesthetic infusion was associated with a signifi cant reduction in pain VAS on movement on all three post-operative days (day 1 weighted mean difference: -1.14; 95% CI: -2.24 to -0.041; P = 0.04, day 2 weighted mean difference: -0.97, 95% CI: -1.91to -0.029; P = 0.04, day 3 weighted mean difference: -0.61; 95% CI: 1.01 to -0.20; P = 0.0038). Local an- aesthetic wound infusion was associated with a signifi - cant decrease in total opioid consumption (weighted mean difference: -40.13; 95% CI: -76.74 to -3.53; P = 0.03). There was no signifi cant decrease in length of stay (weighted mean difference: -20.87; 95% CI: -46.96 to 5.21; P = 0.12) or return of bowel function (weighted mean difference: -9.40; 95% CI: -33.98 to 15.17; P = 0.45). CONCLUSION: The results of this systematic re- view and meta-analysis suggest that local anaesthetic wound infusion following laparotomy for major color- ectal surgery is a promising technique but do not pro- vide conclusive evidence of benefi t. Further research is required including cost-effectiveness analysis.展开更多

Occlusion pressure, as an important parameter of infusion pumps, should be detected when an occlusion occurred. How-ever, infusion pumps’ occlusion pressure could not be tested and the performance of these pumps is not known to us. In order to test the occlusion pressure of infusion pump, a testing system has been put forward according to standards of IEC 60601-2-24:1998/ GB 9706.27- 2005. The system is comprised of sensor, acquisition card, three-way tap and so on;this system is controlled by a PC. At the same time, sampling rate could be changed if necessary and test time could be recorded. And then the characteristics of this system were studied, such as linear, effects of pump rates and different pumps. The system remained linear in a given environment. The higher is the pump rate, the faster is the time to reach occlusion condi-tion. The testing system has been proved to be effective in testing the occlusion pressure of infusion pumps and the accuracy error of pressure is content the demand of ±1% of range.展开更多

HAIC has demonstrated significant potential in managingadvanced HCC, particularly in regions with high prevalence rates. Despite itspromise, several challenges and areas for future research remain. Clinical studieshave substantiated the efficacy of HAIC in enhancing survival outcomes forpatients with advanced hepatic carcinoma. Notably, combination therapiesinvolving immune checkpoint inhibitors, such as lenvatinib and programmeddeath-1 inhibitors, have shown substantial improvements in median overallsurvival and progression-free survival compared to systemic chemotherapy.These combination therapies have also exhibited superior response rates anddisease control, with manageable and often less severe adverse events relative tosystemic treatments. This article is based on the review by Zhou et al and aims todiscuss the current status and future directions in the treatment of HCC, emphasizingthe role of HAIC and its integration with novel therapeutic agents.展开更多

Methods: A total of 200 patients who used intravenous indwelling needles during hospital treatment from July to October 2022 were selected and randomly divided into an observation group and a control group, with 100 patients in each group. Patients in the control group received routine nursing methods, while those in the observation group were managed using the safety risk management method of the infusion project team. The tube blocking rate and tube removal rate were compared between the two groups. Results: The one-time puncture success rate and the standard implementation rate of intravenous indwelling needle use in the observation group were significantly higher than those in the control group. The total incidence of complications in the observation group was significantly lower than that in the control group, and patient satisfaction in the observation group was notably higher, with statistically significant differences (P < 0.05). Conclusion: The application of an infusion project team in the safety risk management of indwelling needle use is effective and has positive impacts on improving the one-time puncture success rate, the standard implementation rate of intravenous indwelling needle use, and patient satisfaction. It is a practice worth promoting in clinical settings.展开更多

The main factors affecting the compression response under investigation include, the vacuum pressure, the loading and unloading repeatability on the preform, the layup design, the kinds of fabrics, and the resin viscosity. Besides, the effects of some internal factors such as nesting and elastic recovery of fibers, lubrication of resin, friction between fibers, and so on, are also studied. In the end, this article expatiates the meaning of the matching requirements of the permeability of the preform and that of the distribution medium.展开更多

Electronic databases including Pubmed, EMbase, Cochrane Library, CNKI, CBM, and VIP were searched using keywords ＂GEM＂, ＂P-LDI＂, and ＂NSCLC＂. Review Manager 5.3 was used to perform the recta-analysis. Primary endpoints were overall response rate （ORR） and 1-year survival rate （1-year SR）. Secondary endpoints were grade 3/4 hematotoxicity and nausea/vomiting. Six randomized controlled trials （RCTs） with a total of 637 patients were included. The results showed that P-LDI was superior in ORR （OR = 1.50, 95% CI： 1.08-2.10, P = 0.02）, but had an equal 1-year SR （OR = 1.27, 95 % CI： 0.90-1.79, P = 0.18） as compared with 30 min-SDl. For grade 3/4 adverse events, there was no significant difference in anemia （OR = 1.84, 95% CI： 0.61-5.57, P = 0.28） and nausea/vomiting （OR = 1.15, 95% CI： 0.63-2.12, P = 0.64） between the two treatments. However, patients with P-LDI experienced less leukopenia （OR = 0.64, 95% CI： 0.43-0.97, P = 0.04） and thrombocytopenia （OR = 0.37, 95% CI： 0.17-0.80, P = 0.01）. P-LDI was superior in terms of ORR, experienced less grade 3/4 thrombocytopenia and leukopenia compared with 30 min-SDI, and could be a viable treatment option for advanced NSCLC.展开更多

However, the efficacy of TACE on large(> 10 cm) stage A-B HCC is far from satisfactory, and it is proposed that hepatic artery infusion chemotherapy(HAIC)might be a better first-line treatment of this disease. Hence, we compared the safety and efficacy of HAIC with the modified FOLFOX(mFOLFOX) regimen and those ofTACE in patients with massive unresectable HCC.Methods: A prospective, non-randomized, phase II study was conducted on patients with massive unresectable HCC. The protocol involved HAIC with the mFOLFOX regimen(oxaliplatin, 85 mg/m^2 intra-arterial infusion; leucovorin,400 mg/m^2 intra-arterial infusion; and fluorouracil, 400 mg/m2 bolus infusion and 2400 mg/m^2 continuous infusion)every 3 weeks and TACE with 50 mg of epirubicin, 50 mg of lobaplatin, 6 mg of mitomycin, and lipiodol and polyvinyl alcohol particles. The tumor responses, time-to-progression(TTP), and safety were assessed.Results: A total of 79 patients were recruited for this study: 38 in the HAIC group and 41 in the TACE group. The HAIC group exhibited higher partial response and disease control rates than did the TACE group(52.6% vs. 9.8%, P < 0.001;83.8% vs. 52.5%, P = 0.004). The median TTPs for the HAIC and TACE groups were 5.87 and 3.6 months(hazard radio[HR] = 2.35,95% confidence interval [CI] = 1.16-4.76, P = 0.015). More patients in the HAIC group than in the TACE group underwent resection(10 vs. 3,P = 0.033). The proportions of grade 3-4 adverse events(AE) and serious adverse events(SAE) were lower in the HAIC group than in the TACE group(grade 3-4 AEs: 13 vs. 27, P = 0.007;SAEs: 6 vs. 15,p = 0.044). More patients in the TACE group than in the HAIC group had the study treatment terminated early due to intolerable treatment-related adverse events or the withdrawal of consent(10 vs. 2,P = 0.026).Conclusions: HAIC with mFOLFOX yielded significantly better treatment responses and less serious toxicity than did TACE. HAIC might represent a feasible and promising first-line treatment for patients with massive unresectable HCC.展开更多
文摘Background Sufentanil target controlled infusion （TCI） provides stable analgesia, better hemodynamic control than a bolus injection of intravenous anesthetics, anticipated recovery and improved quality of anesthesia during perioperative period. This study evaluated the accuracy and feasibility of TCI system for sufentanil at high concentrations in Chinese surgical patients. Methods Twelve low risk adult patients undergoing elective surgery under general anesthesia were included in this study. Sufentanil was administered with a specific TCI system incorporating the population pharmacokinetic data of sufentanil previously reported, using a target effect-site concentration of sufentanil 4 or 6 ng/ml. Sufentanil TCI duration was 30 minutes. Frequent arterial blood samples were taken during and up to 24 hours after sufentanil TCI for determination of plasma sufentanil concentrations by liquid chromatography-mass spectrometry/mass spectrometry. The changes of circulatory system function during the procedure, recovery profile and adverse effects were recorded. Measured plasma sufentanil concentrations were compared with the values predicted by the TCI system. The bias （median performance error, MDPE）, precision （median absolute performance error, MDAPE） and wobble （variability of performance error） of the sufentanil TCI system were determined. Results All patients had stable cardiovascular variables during induction and maintenance of anesthesia. Time to eye opening and extubation were （5.6±1.7） minutes when TCI set to 4 ng/ml and （7.2±2.3） minutes when set to 6 ng/ml. There was no episode of agitation, muscle rigidity or intraoperative awareness. The bias （MDPE）, precision （MDAPE） and wobble of the sufentanil TCI system were -3.7%, 18.9% and 19.6% respectively during TCI, and the MDPE, MDAPE and wobble were -29.1%, 31.7% and 15.0% respectively after TCI （up to 8 hours）. Conclusions The TCI system programmed for sufentanil at 4 or 6 ng/ml was considered acceptable for clinical use in low risk Chinese surgical patients. But the relatively larger MDPE and MDAPE after TCI suggest improvements of the Dharmacokinetic model are needed.
文摘Background:To evaluate the effect of three different combinations of tip designs and infusion systems in torsional phacoemulsification(INFINITI and CENTURION)in patients with cataract.According to the manufacturer,two unique improvements in the Centurion are:active fluid dynamic management system and use of an intrepid balanced tip.The study specifically aimed to evaluate the beneficial effects,if any,of change in tip design and infusion system individually and in combination on both per-operative parameters as well as endothelial health over 6 months.Methods:One hundred and twenty six consenting patients of grade 4.0-6.9 senile cataract were randomized into three groups for phacoemulsification:Group A(n=42):Gravity fed infusion system and 45° Kelman miniflared ABS phaco tip;Group B(n=42):intraocular pressure(IOP)based infusion system and 45° Kelman miniflared ABS phaco tip;Group C(n=42):IOP based infusion system and 45° Intrepid balanced phaco tip.The cumulative dissipated energy(CDE),estimated fluid usage(EFU)and total aspiration time(TAT)were compared peroperatively.The endothelial parameters were followed up postoperatively for six months.Results:The three arms were matched for age(p=0.525),gender(p=0.96)and grade of cataract(p=0.177).Group C was associated with significant reductions in CDE(p=0.001),EFU(p<0.0005)as well as TAT(p=0.001)in comparison to the other groups.All three groups had comparable baseline endothelial cell density(p=0.876)and central corneal thickness(p=0.561).On post-operative evaluation,although all groups were comparable till 3 months,by 6 months,the percentage losses in endothelial cell density were significantly lower in group C as compared to the other groups.Conclusions:Use of an IOP based phacoemulsification system in association with use of the Intrepid balanced tip reduces the CDE,EFU and TAT in comparison to a gravity fed system with a mini flared tip or IOP based system with a mini flared tip while also providing better endothelial preservation thus favouring the use of an IOP fed system with a balanced tip.
文摘AIM:To provide a specifi c review and meta-analysis of the available evidence for continuous wound infusion of local anaesthetic agents following midline laparoto-my for major colorectal surgery. METHODS: Medline, Embase, trial registries, conference proceedings and article reference lists were searched to identify randomised, controlled trials of continuous wound infusion of local anaesthetic agents following colorectal surgery. The primary outcomes were opioid consumption, pain visual analogue scores (VASs), return to bowel function and length of hospital stay. Weighted mean difference were calculated for continuous outcomes. RESULTS: Five trials containing 542 laparotomy wounds were eligible for inclusion. There was a sig- nificant decrease in post-operative pain VAS at rest on day 3 (weighted mean difference: -0.43; 95% CI: -0.81 to -0.04; P = 0.03) but not on post-operative day 1 and 2. Local anaesthetic infusion was associated with a signifi cant reduction in pain VAS on movement on all three post-operative days (day 1 weighted mean difference: -1.14; 95% CI: -2.24 to -0.041; P = 0.04, day 2 weighted mean difference: -0.97, 95% CI: -1.91to -0.029; P = 0.04, day 3 weighted mean difference: -0.61; 95% CI: 1.01 to -0.20; P = 0.0038). Local an- aesthetic wound infusion was associated with a signifi - cant decrease in total opioid consumption (weighted mean difference: -40.13; 95% CI: -76.74 to -3.53; P = 0.03). There was no signifi cant decrease in length of stay (weighted mean difference: -20.87; 95% CI: -46.96 to 5.21; P = 0.12) or return of bowel function (weighted mean difference: -9.40; 95% CI: -33.98 to 15.17; P = 0.45). CONCLUSION: The results of this systematic re- view and meta-analysis suggest that local anaesthetic wound infusion following laparotomy for major color- ectal surgery is a promising technique but do not pro- vide conclusive evidence of benefi t. Further research is required including cost-effectiveness analysis.

文摘Objective:This study aimed to introduce and evaluate a new embolization technique for the right gastric artery(RGA) during percutaneous implantation of a port-catheter system for hepatic arterial infusion chemotherapy(HAIC).Methods:From January 2013 to January 2017,159 patients with unresectable advanced liver cancer underwent percutaneous implantation of a port-catheter system.In 86 of these patients(56 men;aged 28-88 years;mean:60.6±12.0 years),in whom the RGA was obvious on arteriography,embolization of RGA was attempted using microcoils to protect the gastric mucosa during HAIC.In the first phase(first three years),antegrade embolization of the RGA using a 2.7 Fr microcatheter was performed in 55 patients.In the second phase(next two years),embolization of the RGA was attempted by combining antegrade embolization and retrograde embolization through the left gastric artery(LGA) in 31 patients.The success rates and the incidence of acute gastroduodenal mucosal toxicity(AGMT) in these two groups were compared.Results:The total success rate of the RGA embolization was 70.9%.The success rate was 83.9% in 31 patients who underwent combined antegrade and retrograde embolization,which was significantly higher than that of antegrade embolization alone(63.6%) performed in 55 patients(p=0.047).No complications related to embolization of RGA were documented.The incidence of AGMT was 29.1%(16/55) in patients in the first phase,which was significantly higher than that in the patients in the second phase(9.7%,3/31)(p=0.037).Conclusion: A combination of retrograde embolization via LGA could increase the success rates of RGA embolization and reduce the incidence of AGMT after HAIC.
文摘Objective:To study the effect of bronchial arterial infusion chemotherapy combined with elemene on the malignant lesion molecules and systemic immune response in patients with advanced lung cancer.Methods:A total of 78 patients diagnosed with advanced lung cancer in our hospital between April 2013 and March 2016 were selected as research subjects and randomly divided into observation group who accepted bronchial arterial infusion chemotherapy combined with elemene therapy and control group who accepted bronchial arterial infusion chemotherapy. After 4 weeks of treatment, tumor lesions were collected to determine the expression of proliferation and invasion molecule, and serum was collected to determine the levels of immune cell-related cytokines.Results:After 4 weeks of treatment, TCF3, Livin, Bcl-2, HOXB7, PTTG1, Vimentin, E-cadherin, Rap2a andβ-catenin protein expression in tumor lesions of observation group were significantly lower than those of control group;serum IFN-γ level of observation group was significantly higher than that of control group while IL-4, IL-9, IL-10 and TGF-β levels were significantly lower than those of control group.Conclusions:Bronchial arterial infusion chemotherapy combined with elemene can inhibit the expression of proliferation and invasion of molecules in tumor lesions and improve the systemic anti-tumor immune response in patients with advanced lung cancer.
文摘Reliability of medical devices such as infusion pumps is extremely important because these devices are being used in patients who are in critical condition. Occlusion pressure, as an important parameter of infusion pumps, should be detected when an occlusion occurred. How-ever, infusion pumps’ occlusion pressure could not be tested and the performance of these pumps is not known to us. In order to test the occlusion pressure of infusion pump, a testing system has been put forward according to standards of IEC 60601-2-24:1998/ GB 9706.27- 2005. The system is comprised of sensor, acquisition card, three-way tap and so on;this system is controlled by a PC. At the same time, sampling rate could be changed if necessary and test time could be recorded. And then the characteristics of this system were studied, such as linear, effects of pump rates and different pumps. The system remained linear in a given environment. The higher is the pump rate, the faster is the time to reach occlusion condi-tion. The testing system has been proved to be effective in testing the occlusion pressure of infusion pumps and the accuracy error of pressure is content the demand of ±1% of range.
文摘BACKGROUND Propofol has been widely used in bidirectional gastrointestinal endoscopy sedation;however,it frequently leads to cardiovascular adverse events and respiratory depression.Propofol target-controlled infusion(TCI)can provide safe sedation but may require higher dosages of propofol.On the contrary,etomidate offers hemodynamic stability.AIM To evaluate the effect of different dose etomidate added to propofol TCI sedation during same-visit bidirectional endoscopy.METHODS A total of 330 patients from Fujian Provincial Hospital were randomly divided into three groups:P,0.1EP,and 0.15EP.Patients in the P group received propofol TCI only,with an initial effect-site concentration of the propofol TCI system of 3.0 mg/mL.Patients in the 0.1EP and 0.15EP groups received 0.1 and 0.15 mg/kg etomidate intravenous injection,respectively,followed by propofol TCI.RESULTS Patients in the 0.15EP group had higher mean blood pressure after induction than the other groups(P group:78 mmHg,0.1EP group:82 mmHg,0.15EP group:88 mmHg;P<0.05).Total doses of propofol consumption significantly decreased in the 0.15EP group compared with that in the other groups(P group:260.6 mg,0.1EP group:228.1 mg,0.15EP group:201.2 mg;P<0.05).The induction time was longer in the P group than in the other groups(P group:1.9±0.7 minutes,0.1EP group:1.2±0.4 minutes,0.15EP group:1.1±0.3 minutes;P<0.01).The recovery time was shorter in the 0.15EP group than in the other groups(P group:4.8±2.1 minutes,0.1EP group:4.5±1.6 minutes,0.15EP group:3.9±1.4 minutes;P<0.01).The incidence of hypotension(P group:36.4%,0.1EP group:29.1%,0.15EP group:11.8%;P<0.01)and injection pain was lower in the 0.15EP group than in the other groups(P<0.05).Furthermore,the incidence of respiratory depression was lower in the 0.15EP group than in the P group(P<0.05).Additionally,the satisfaction of the patient,endoscopist,and anesthesiologist was higher in the 0.15EP group than in the other groups(P<0.05).CONCLUSION Our findings suggest that 0.15 mg/kg etomidate plus propofol TCI can significantly reduce propofol consumption,which is followed by fewer cardiovascular adverse events and respiratory depression,along with higher patient,endoscopist,and anesthesiologist satisfaction.
文摘This study examines the pivotal findings of the network meta-analysis of Zhou et al,which evaluated the efficacy of hepatic arterial infusion chemotherapy and combination therapies for advanced hepatocellular carcinoma(HCC).This meta-analysis suggests that therapeutic combinations have greater efficacy than do standard treatments.The article highlights the key insights that have the potential to shift current clinical practice and enhance outcomes for patients with advanced HCC.Additionally,this article discusses further research that can be conducted to optimize these treatments and achieve personalized care for patients with HCC.
文摘Hepatic arterial infusion(HAI)chemotherapy,first introduced in the 1980s,has gained recognition as an effective locoregional treatment for colorectal liver metastasis(CRLM).Initially used for unresectable liver metastases,HAI’s app-lication has expanded to the adjuvant setting following hepatic resection,with early studies indicating improved hepatic disease-free survival.Recent research demonstrates that combining HAI with modern systemic therapies enhances conversion to resectability and prolongs both recurrence-free and overall survival,even in heavily pretreated patients with diverse RAS mutational statuses.Person-alization through approaches like microsatellite instability status and dose mo-difications further optimize outcomes.However,the complexity of HAI requires expertise across multidisciplinary teams,limiting its widespread adoption to specialized centers.Ongoing clinical trials continue to investigate HAI’s role in CRLM management,highlighting its potential to become a cornerstone of liver-directed therapy.We explore how HAI chemotherapy,in combination with personalized medicine,can advance treatment strategies for metastatic colorectal cancer.
文摘Hepatic arterial infusion chemotherapy (HAIC) is an advanced targeted therapeuticapproach for hepatocellular carcinoma (HCC), the most common type ofprimary liver cancer. HAIC has demonstrated significant potential in managingadvanced HCC, particularly in regions with high prevalence rates. Despite itspromise, several challenges and areas for future research remain. Clinical studieshave substantiated the efficacy of HAIC in enhancing survival outcomes forpatients with advanced hepatic carcinoma. Notably, combination therapiesinvolving immune checkpoint inhibitors, such as lenvatinib and programmeddeath-1 inhibitors, have shown substantial improvements in median overallsurvival and progression-free survival compared to systemic chemotherapy.These combination therapies have also exhibited superior response rates anddisease control, with manageable and often less severe adverse events relative tosystemic treatments. This article is based on the review by Zhou et al and aims todiscuss the current status and future directions in the treatment of HCC, emphasizingthe role of HAIC and its integration with novel therapeutic agents.
文摘In this manuscript,we comment on the article by Zhou et al,who assessed the efficacy of hepatic arterial infusion chemotherapy(HAIC)and its combination strategies for advanced hepatocellular carcinoma(HCC)using network metaanalysis methodology.We focus specifically on the potential advantages and role of HAIC in the treatment algorithm for advanced HCC.However,there remains numerous knowledge gaps before the role of HAIC can be established.There is significant heterogeneity of HAIC regimes with difficult interpretation of the clinical outcomes.Additionally,there is a lack of direct comparative data between HAIC,systemic chemotherapy,novel immunotherapies and targeted therapies.The underlying biochemical mechanisms that might explain the efficacy of HAIC and its effect on the HCC microenvironment requires further research.In the developing era of nanotechnology and targeted drug delivery systems,there is potential for integration of HAIC with novel technologies to effectively treat advanced HCC whilst minimising systemic complications.
文摘The rapid evolution of systemic therapies for hepatocellular carcinoma(HCC),one of the most common types of liver cancer,has attracted significant attention especially to hepatic arterial infusion chemotherapy(HAIC)as a highly promising treatment approach.This method,which delivers chemotherapy directly into the liver's arterial supply,is designed to maximize the concentration of anti-cancer drugs at the tumor site while minimizing systemic side effects.Despite the potential and the encouraging results observed in various studies,HAIC has not yet achieved widespread acceptance and utilization.Sorafenib is a widely used systemic therapy that targets multiple pathways involved in tumor growth and angiogenesis,while transarterial chemoembolization(TACE)is a locoregional therapy that combines arterial embolization with chemotherapy.These treatments have been the mainstay of HCC management,yet they have limitations that HAIC may potentially overcome.This article specifically comments on the network meta-analysis that examined the current research status of HAIC,highlighting its effectiveness and safety profile in comparison to established standard treatments such as Sorafenib and TACE.Through an extensive review of existing studies,the authors conclude that patients receiving HAIC often experience better survival rates and longer periods without disease progression compared to those receiving Sorafenib or TACE.

文摘BACKGROUND Studies have shown that patients with type 1 diabetes mellitus on continuous subcutaneous insulin infusion(CSII)require a lower dose of insulin than those treated with multiple daily injections(MDIs).However,it is unclear whether this is also the case for patients with type 2 diabetes mellitus(T2DM).AIM To compare insulin dosage requirements between CSII and MDI in T2DM,iden-tifying influencing factors associated with both therapeutic modalities.METHODS A total of 954 patients with T2DM were divided into two groups:CSII and MDI groups.The total daily insulin dose(TDD),TDD per kilogram per day(TDD/kg),and ratio of total basal insulin dose to TDD(%TBa)required to achieve the target blood glucose levels were compared between the two groups.In addition,factors affecting insulin dosage were analyzed in both groups of patients.RESULTS Compared to the CSII group,the MDI group required a higher TDD[median(interquartile)]:30.00(24.00,38.00)U/day vs 26.40(21.60,32.40)U/day;P<0.01,TDD/kg and%TBa.In the MDI group and CSII groups,an increase in TDD was independently associated with an increase in body mass index(BMI),waist circumference(WC),fasting plasma glucose(FPG),and glycated hemoglobin(HbA1c).The pathophysiology of type 2 diabetes mellitus(T2DM)mainly involves insulin resistance and progressiveβ-cell failure,which leads to increased blood glucose levels(hyperglycemia)[1-3].Treatment for T2DM includes antidiabetic medications and insulin therapy[4,5].Patients with T2DM withβ-cell failure usually require insulin therapy[6-8].Continuous subcutaneous insulin infusion(CSII)and multiple daily injections(MDIs)are two major insulin therapies for controlling hyperglycemia in these patients.However,excessive insulin therapies may cause problems such as hypoglycemia,weight gain,and iatrogenic hyperinsulinemia[9].Therefore,attention should be paid to the dosage of insulin used.The establishment of insulin regimens for CSII and MDI therapies is primarily guided by physicians’empirical judgment.To date,there have been few clear guidelines or recommendations on the appropriate insulin dose during CSII and MDI treatment for T2DM[10].Yang et al[11]studied insulin doses and related factors in the CSII treatment of patients with T2DM[12].However,these studies did not cover the dose setting and related factors in MDI treatment.Previous studies have shown that patients with type 1 diabetes mellitus treated with CSII require less insulin than those treated with MDIs[13-15].However,it is unclear whether patients with T2DM on CSII also require less insulin than patients on MDI.Therefore,the present study determined the difference in insulin dosages between CSII and MDI therapies and evaluated the related factors in patients with T2DM.It also systematically analyzed the insulin dose characteristics of MDI and CSII in 954 hospitalized patients with T2DM,aiming to optimize the insulin dosage regimen and provide clinical references for guiding the application of CSII and MDI in patients with T2DM.

文摘Selenium is one of the important trace elements in the human body.Its deficiency will directly affect human health.With people's attention to health,the content of selenium in food has gradually attracted attention.However,detecting selenium compounds in complex samples remains a challenge.In this work,we built an online heating-reaction device.This device combines the electrospray extraction ionization mass spectrometry(EESI-MS)with the heating reaction device,which can simultaneously detect various selenium compounds in complex liquid samples.Under acidic conditions,the sample was heated and catalyzed by a heating reaction device,so that the SeO~(2-)_(3)and O-phenylenediamine(OPD)could generate 1,3-dihydro-2,1,3-benzoselenadiazole.Based on the above reactions,we can detect organic selenium,inorganic selenium and other compounds in liquid samples by organic mass spectrometry.In this experiment,we determined the content of three forms of selenium:selenomethionine(SeMet),l-selenocystine(SeCys(2)),and sodium selenite.The calibration curves for SeMet,SeCys(2),and sodium selenite showed strong linearity within a range of 0.50-50.00μg/L.The limits of detection(LOD)for the three compounds were 0.22,0.27,and 0.41μg/L,respectively.The limits of quantification(LOQ)were 0.68,0.81,and 1.23μg/L,respectively.Spiked recoveries at three levels ranged from 98.8%to 106.1%.In addition,this method can simultaneously detect three selenium compounds and three other specific chemical components in tea infusion samples,providing a rapid and efficient method for identifying tea quality.
文摘This article provides an in-depth analysis of the study conducted by Wang et al,which explores hepatic arterial infusion chemotherapy and its synergistic strategies in managing advanced hepatocellular carcinoma(HCC).HCC ranks as the fourth most common cause of cancer-related mortality globally and is frequently associated with portal vein tumor thrombus(PVTT).The approach to managing HCC,particularly when PVTT is present,diverges markedly between Eastern and Western practices.These differences are rooted in variations in epidemiology,etiology,pathology,comorbidities,and prognosis.The paper delves into the diagnosis,classification,and treatment strategies for HCC with PVTT,as well as the evolving role and advancements of hepatic arterial infusion chemotherapy in the therapeutic landscape of HCC.

文摘BACKGROUND Hepatic artery infusion chemotherapy(HAIC)is a widely used local therapeutic approach for intermediate to advanced-stage hepatocellular carcinoma(HCC),exhibiting considerable efficacy.However,the prevalence of postoperative pain highlights the importance of pain management.Owing to the limitations inherent in existing pain management strategies,this study investigates and assesses the analgesic effectiveness of a multimodal treatment protocol in mitigating pain after HAIC procedures.AIM To provide patients with a more comprehensive and effective pain management strategy.METHODS A total of 100 patients with primary HCC who underwent HAIC were randomly assigned to a control group(n=50)and a multimodal group(n=50).Baseline characteristics and perioperative data were collected.Upon enrollment,patients in the multimodal group received parecoxib(40 mg)30 minutes before HAIC,followed by 48 hours of patient-controlled analgesia with sufentanil.In contrast,the control group underwent standard preoperative preparation(psychological support)and received dezocine(5 mg)intraoperatively,with intravenous flurbiprofen(100 mg)administered every 12 hours for 48 hours postoperatively.RESULTS Compared to the control group,the multimodal analgesia group exhibited significantly lower resting and movement visual analog scale pain scores at postoperative 0,2,4,6,and 12 hours(P<0.05).Furthermore,the multimodal group experienced a reduced incidence of postoperative nausea and vomiting,as well as a lower overall frequency of adverse events,compared to the control group(P<0.05).Patient satisfaction was also significantly higher in the multimodal group than in the control group(P<0.05).CONCLUSION Our study demonstrates that multimodal analgesia is effective in reducing postoperative pain,minimizing adverse reactions,and improving patient satisfaction in HCC patients undergoing HAIC.This approach provides valuable clinical strategies for optimizing pain management in this patient population.
文摘Objective: To explore the effectiveness of applying an infusion project team in the safety risk management of indwelling needle use. Methods: A total of 200 patients who used intravenous indwelling needles during hospital treatment from July to October 2022 were selected and randomly divided into an observation group and a control group, with 100 patients in each group. Patients in the control group received routine nursing methods, while those in the observation group were managed using the safety risk management method of the infusion project team. The tube blocking rate and tube removal rate were compared between the two groups. Results: The one-time puncture success rate and the standard implementation rate of intravenous indwelling needle use in the observation group were significantly higher than those in the control group. The total incidence of complications in the observation group was significantly lower than that in the control group, and patient satisfaction in the observation group was notably higher, with statistically significant differences (P < 0.05). Conclusion: The application of an infusion project team in the safety risk management of indwelling needle use is effective and has positive impacts on improving the one-time puncture success rate, the standard implementation rate of intravenous indwelling needle use, and patient satisfaction. It is a practice worth promoting in clinical settings.
文摘The final thickness of a product after the vacuum infusion process （VIP）, which is equal to the fiber volume fraction, depends in part on the compression responses of the preform because one of the mold faces is flexible in VIE This study aims at investigating the compression responses of different fabrics under dry or wet conditions. The main factors affecting the compression response under investigation include, the vacuum pressure, the loading and unloading repeatability on the preform, the layup design, the kinds of fabrics, and the resin viscosity. Besides, the effects of some internal factors such as nesting and elastic recovery of fibers, lubrication of resin, friction between fibers, and so on, are also studied. In the end, this article expatiates the meaning of the matching requirements of the permeability of the preform and that of the distribution medium.
文摘To evaluate the efficacy and safety of gemcitabine （GEM） at 30 min standard-dose infusion （30 min-SDI） compared with prolonged low-dose infusion （P-LDI） in patients with advanced non-small-cell lung cancer （NSCLC）. Electronic databases including Pubmed, EMbase, Cochrane Library, CNKI, CBM, and VIP were searched using keywords ＂GEM＂, ＂P-LDI＂, and ＂NSCLC＂. Review Manager 5.3 was used to perform the recta-analysis. Primary endpoints were overall response rate （ORR） and 1-year survival rate （1-year SR）. Secondary endpoints were grade 3/4 hematotoxicity and nausea/vomiting. Six randomized controlled trials （RCTs） with a total of 637 patients were included. The results showed that P-LDI was superior in ORR （OR = 1.50, 95% CI： 1.08-2.10, P = 0.02）, but had an equal 1-year SR （OR = 1.27, 95 % CI： 0.90-1.79, P = 0.18） as compared with 30 min-SDl. For grade 3/4 adverse events, there was no significant difference in anemia （OR = 1.84, 95% CI： 0.61-5.57, P = 0.28） and nausea/vomiting （OR = 1.15, 95% CI： 0.63-2.12, P = 0.64） between the two treatments. However, patients with P-LDI experienced less leukopenia （OR = 0.64, 95% CI： 0.43-0.97, P = 0.04） and thrombocytopenia （OR = 0.37, 95% CI： 0.17-0.80, P = 0.01）. P-LDI was superior in terms of ORR, experienced less grade 3/4 thrombocytopenia and leukopenia compared with 30 min-SDI, and could be a viable treatment option for advanced NSCLC.

文摘Background: Transarterial chemoembolization(TACE) is recommended as the standard care for unresectable hepatocellular carcinoma(HCC) at Barcelona Clinic Liver Cancer(BCLC) stage A-B. However, the efficacy of TACE on large(> 10 cm) stage A-B HCC is far from satisfactory, and it is proposed that hepatic artery infusion chemotherapy(HAIC)might be a better first-line treatment of this disease. Hence, we compared the safety and efficacy of HAIC with the modified FOLFOX(mFOLFOX) regimen and those ofTACE in patients with massive unresectable HCC.Methods: A prospective, non-randomized, phase II study was conducted on patients with massive unresectable HCC. The protocol involved HAIC with the mFOLFOX regimen(oxaliplatin, 85 mg/m^2 intra-arterial infusion; leucovorin,400 mg/m^2 intra-arterial infusion; and fluorouracil, 400 mg/m2 bolus infusion and 2400 mg/m^2 continuous infusion)every 3 weeks and TACE with 50 mg of epirubicin, 50 mg of lobaplatin, 6 mg of mitomycin, and lipiodol and polyvinyl alcohol particles. The tumor responses, time-to-progression(TTP), and safety were assessed.Results: A total of 79 patients were recruited for this study: 38 in the HAIC group and 41 in the TACE group. The HAIC group exhibited higher partial response and disease control rates than did the TACE group(52.6% vs. 9.8%, P < 0.001;83.8% vs. 52.5%, P = 0.004). The median TTPs for the HAIC and TACE groups were 5.87 and 3.6 months(hazard radio[HR] = 2.35,95% confidence interval [CI] = 1.16-4.76, P = 0.015). More patients in the HAIC group than in the TACE group underwent resection(10 vs. 3,P = 0.033). The proportions of grade 3-4 adverse events(AE) and serious adverse events(SAE) were lower in the HAIC group than in the TACE group(grade 3-4 AEs: 13 vs. 27, P = 0.007;SAEs: 6 vs. 15,p = 0.044). More patients in the TACE group than in the HAIC group had the study treatment terminated early due to intolerable treatment-related adverse events or the withdrawal of consent(10 vs. 2,P = 0.026).Conclusions: HAIC with mFOLFOX yielded significantly better treatment responses and less serious toxicity than did TACE. HAIC might represent a feasible and promising first-line treatment for patients with massive unresectable HCC.
