This study aims to develop and validate a clinical prediction model for postoperative recurrence in pancreatic cancer patients, incorporating multiple preoperative, intraoperative, and postoperative factors to assist clinical decision-making. Methods: A retrospective study was conducted on 216 patients who underwent surgical treatment for pancreatic malignancy at the First Affiliated Hospital of Chongqing Medical University between January 2015 and January 2023. An independent external validation cohort of 76 patients from the Second Affiliated Hospital of Chongqing Medical University was used to validate the model. Seven independent risk factors for postoperative recurrence were identified through univariate and multivariate Cox regression analyses. The model’s performance was evaluated using the concordance index (C-index) and ROC curves, and its accuracy and clinical value were assessed using calibration curves and decision curve analysis (DCA). Results: The predictive model demonstrated good discriminatory power, with a C-index of 0.72 in the training cohort and 0.66 in the validation cohort. The ROC curves for predicting recurrence at 3, 6, and 12 months postoperatively showed AUC values ranging from 0.72 to 0.83, indicating strong predictive value. Calibration curves and DCA confirmed the model’s accuracy and clinical utility. Conclusion: This study successfully developed and validated a clinical prediction model that incorporates seven independent risk factors for postoperative recurrence in pancreatic cancer. The model provides a useful tool for predicting recurrence risk, aiding in the identification of high-risk patients, and informing clinical decision-making.展开更多

Methods A total number of 456 patients from 3 centers with paralysis of oculomotor nerve were randomly divided into an acupoint injection group and a control group with 228 cases each. Patients in the acupoint injection group were treated with injection of Chinese herbal medicines to Jingming （晴明 BL 1）, Yangbai （阳白GB 14}, Sibai （四白 ST 24 Tongziliao （瞳子髎 GB I） on the affected side, and Ganshu （肝俞 BL 18） on both sides, Compound Angelica Injection was the main drug, and the corresponding acupoints and other injection drugs were also used according to differentiation of syndrome. Patients in the control group were treated with common western medicine. The treatment was given once a day, 10 times constituted one course with 3 days of interval. After 3 courses, the effect was assessed. TCM syndrome score, eyeball movement degree, the sizes of oculi rimae and pupil of the two groups were recorded before and after treatment. Results The effective rate of acupoint injection group was 91.7% （209/228）, and that of the control group was 73.6% （168/228）. There was statistical significance in comparing the difference between the two groups （P〈0.05）. TCM syndrome scores of the two groups after the treatment became less obviously than those before the treatment （P〈0.01, P〈0.05）, the score of acupoint injection group was more reduced than that of the control group （P〈0.05）. Eyeball movement degree and oculi rimae were enlarged and the pupil reduced in the affected eye in both groups after the treatment Call P〈0.05）. The musculus rectus medialis for the eyeball movement in the acupoint injection group was more improved than that of the control group, and the oculi rimae was bigger in the acupoint injection group than that in the control group （both P〈0.05）. Conclusion Acupoint injection therapy with Chinese herbal medicines has assured effect on the treatment of oculomotor paralysis.展开更多

METHODS： Consecutive patients who had been admitted to the Division of Gastroenterology with gastrointestinal symptoms were enrolled from March to April 2005. Of those who had been diagnosed with clonorchiasis, epidemiology and correlation between infection and hepatobiliary diseases were surveyed by questionnaire. RESULTS： Of 3080 patients with gastrointestinal diseases, 396 （12.9%） had clonorchiasis and 1140 patients （37.2%） had a history of eating raw freshwater fish. Of those with a history of raw freshwater fish ingestion, 238 （20.9%） patients had clonorchiasis. Cholangiocarcinoma was more prevalent in C. sinensis-infected patients than nonnfected patients [34/396 （8.6%） vs 145/2684 （5.4%）, P = 0.015]. Cholangiocarcinoma and clonorchiasis showed statistically significant positive cross-relation （P = 0.008）. Choledocholithiasis, cholecystolithiasis, cholangitis, hepatocellular carcinoma, and biliary pancreatitis did not correlate with clonorchiasis. CONCLUSION： Infection rate of clonorchiasis was still high in patients with gastrointestinal diseases in Korea, and has not decreased very much during the last two decades. Cholangiocarcinoma was related to clonorchiasis, which suggested an etiological role for the parasite.展开更多

Significant improvements in ...BACKGROUND Nigeria bears the greatest burden of diabetes prevalence in Sub-Saharan Africa. Diabetic foot ulcer (DFU) is a serious and potentially life-threatening complication of diabetes. Significant improvements in diabetic foot incidence and outcomes have been recorded in many Western countries in the past decade. However, the current burden of DFU in Nigeria is largely unknown. AIM To evaluate the patients’ profile, ulcer characteristics, associated co-morbidities and outcome of patients with DFU in Nigeria. METHODS Multicenter evaluation of diabetic foot ulcer in Nigeria was a one year multicenter observational study of patients hospitalized for DFU in six tertiary health institutions in Nigeria from March 2016 to March 2017. Demographic and diabetes information, ulcer characteristics and associated co-morbidities were assessed. Relevant laboratory and imaging studies were performed. All patients received appropriate multi-disciplinary care and were followed up until discharge or death. Outcome variables of interest were ulcer healing, lower extremity amputation (LEA), duration of hospitalization and mortality. RESULTS A total of 336 patients (55.1% male) with mean age of 55.9 ± 12.5 years were enrolled into this study. Majority (96.1%) had type 2 diabetes. Only 25.9% of the subjects had prior foot care knowledge. Most of the subjects presented late to the hospital and median (IQR) duration of ulcer at presentation was 39 (28-54) d. Ulcers were already advanced (Wagner grades ≥ 3) in 79.2% of the subjects while 76.8% of the ulcers were infected at the time of admission. The commonest comorbidities were systemic hypertension, anemia and hyperglycemic emergencies. One hundred and nineteen subjects (35.4%) suffered LEA while 10.4% left against medical advice. The median (IQR) duration of hospitalization was 52.0 (29-66) d with case fatality rate of 20.5%. CONCLUSION The burden of DFU in Nigeria is very high. The major gaps include low level of foot care knowledge among diabetic patients, overdependence on self-medication and unorthodox medicine following development of foot ulceration, late hospital presentation, and high amputation and mortality rates. Extensive foot care education within the framework of a multi-disciplinary foot care team is highly desirable.展开更多

A total of 143 pa-tients were assigned to either the ZYXH group or the ZSQG group using a random number table. The ZYXH group received ZYXH three times daily for 6 months and the ZSQG group received ZSQG three times daily for 6 months. Mammary nucleus diameter; the results of uterus, ovarian, and maximum follicle measures; and Chinese medicine symptom pattern scores were compared at baseline and after 3 months and 6 months of treatment.RESULTS: After 3 months' treatment, there were no significant differences between the two groups in mammary nucleus index changes(left 3.4 ± 3.1 vs3.5 ± 3.1, P = 0.790; right 3.0 ± 2.9 vs 3.6 ± 3.0, P =0.719). The uterine volume in the ZYXH group was smaller than that in the ZSQG group(2.1 ± 1.6 vs2.6 ± 2.2, P = 0.006). There were no significant between-group differences in ovarian volume and maximum follicular diameter on either side(ovarian volume: left 1.2 ± 0.7 vs 1.3 ± 0.6, P = 0.8; right1.2 ± 0.7 vs 1.4 ± 1.1, P = 0.984; maximum follicular diameter: left 3.9 ± 1.7 vs 3.5 ± 2.2, P = 0.158; right3.5 ± 1.7 vs 3.9 ± 2.1, P = 0.314).CONCLUSION: ZYXH granules and ZSQG granules both affected the size of the mammary nucleus in girls with PPP, and improved Chinese medicine symptom patterns. ZYXH granules showed slight advantages over ZSQG granules in terms of the decrease in the size of the uterus, ovaries, and ovarian follicles.展开更多

文摘BACKGROUND Antibiotic resistance is a key factor influencing the treatment outcomes of Helicobacter pylori(H.pylori)infection.The antibiotic resistance spectrum of H.pylori varies in different regions.We investigated the current status of antibiotic resistance of H.pylori in Hunan Province and analyzed the factors related to such resistance to provide strategies for the accurate clinical treatment of H.pylori infection.AIM To understand the antibiotic resistance of H.pylori in Hunan Province and provide guidance for the clinical treatment of H.pylori infection.METHODS This study selected patients who underwent gastroscopy in five hospitals in Hunan Province from April 2022 to April 2023.The sensitivity of H.pylori to clarithromycin,levofloxacin,metronidazole,amoxicillin,furazolidone,and tetracycline was detected using the Agar dilution method.RESULTS H.pylori strains from a total of 566 patients were isolated and identified.The resistance rates of H.pylori strains to clarithromycin,levofloxacin,metronidazole,amoxicillin,furazolidone,and tetracycline were 49.2%,37.8%,76.1%,2.3%,1.4%,and 0.7%,respectively.The resistance rates to clarithromycin,levofloxacin,and metronidazole were high in the four regions of Hunan Province,and the overall resistance rates in central Hunan Province were higher than those in other regions.The resistance rates of H.pylori strains to clarithromycin and levofloxacin were significantly different among the different age groups(P<0.05),with the elderly group having a higher resistance rate than the young group.The resistance rate of H.pylori strains to clarithromycin was greater in patients with atrophic gastritis,and the resistance rate to levofloxacin was the lowest in patients with peptic ulcers.CONCLUSION The resistance rate of H.pylori to amoxicillin,clarithromycin,and metronidazole is high in Hunan Province.Age,stomach disease,and H.pylori reinfection may affect the antibiotic resistance of H.pylori.
文摘BACKGROUND The survival rate of pancreatic cancer is low,and there is a lack of effective treatment.AIM To explore the epidemiological characteristics of patients with pancreatic cancer in China and compare multiple chemotherapy regimens at different stages.METHODS This was a retrospective study conducted from 2005 to 2014,involving six cancer hospitals and eight general hospitals across seven geographical regions of China(East,South,North,Central,Southwest,Northwest,and Northeast).Stratified sampling was used based on the population distribution of each region.Efficacy assessments were conducted by Cox proportional hazards regression models.When assessing the effectiveness of various chemotherapy regimens,traditional drugs such as gemcitabine used as monotherapy served as the reference.RESULTS A total of 3256 patients were included.The median follow-up time was 407 days,and the median overall survival was 183 days.At diagnosis,56%of patients were already in stage IV.Chemotherapy was administered to 39.73%of patients.In the adjuvant therapy phase,gemcitabine+fluorouracil was superior to gemcitabine monotherapy[hazard ratio(HR)=0.35,95%confidence interval(CI):0.14-0.89].In fluorouracil-based regimens,other combination regimens did not show effectiveness relative to monotherapy.For first-line treatment in patients with advanced disease,tegafur alone(HR=0.20,95%CI:0.06-0.66),gemcitabine plus cisplatin(HR=0.16,95%CI:0.04-0.70),and tegafur,gemcitabine plus platinum-based agents(HR=0.32,95%CI:0.11-0.91)were associated with a lower risk of death compared to gemcitabine alone.In second-line treatment,there were no significant differences in efficacy among various drugs,but FOLFIRINOX(irinotecan+oxaliplatin+leucovorin+5-fluorouracil)had an outstanding point estimate(HR=0.10,95%CI:0.01-1.27).CONCLUSION In China,pancreatic cancer is often diagnosed at advanced stages,emphasizing the need for early diagnosis and treatment.Combined therapies in adjuvant and first-line settings may reduce the risk of death compared with monotherapy,and FOLFIRINOX might offer more significant benefits in second-line treatment.
文摘Objective:To evaluate the impact of subcutaneous tunneling on peripherally inserted central catheters(PICCs)dislodgement and malposition.Dislodged or malpositioned PICCs can lead to improper treatment.The subcutaneous tunneling strategy may be effective,but there is insufficient evidence,and proximal movement has not been explored.Methods:We randomized 630 patients who needed PICCs placement to either the tunneled PICCs(experimental group)or the non-tunneled PICCs(control group).Dislodgement and malposition of the catheter were the primary outcomes,and catheter-related infection(CRI)and catheter-related thrombosis(CRT)were the secondary outcomes.Results:Subcutaneous tunneling does not significantly reduce distal catheter movement,but it significantly reduces proximal catheter movement(4.3%vs.9.9%,P=0.007),which may explain the lower incidence of CRI(2.0%vs.5.3%,P=0.030)and CRT(3.6%vs.12.5%,P<0.001).Conclusions:Although subcutaneous tunneling does not significantly improve catheter prolapse,it should still be used clinically because proximal catheter movement can be a more serious problem associated with CRI and CRT.

文摘Objective To explore and quantify the association of hot night exposure during the sperm development period(0–90 lag days) with semen quality.Methods A total of 6,640 male sperm donors from 6 human sperm banks in China during 2014–2020were recruited in this multicenter study.Two indices(i.e.,hot night excess [HNE] and hot night duration[HND]) were used to estimate the heat intensity and duration during nighttime.Linear mixed models were used to examine the association between hot nights and semen quality parameters.Results The exposure-response relationship revealed that HNE and HND during 0–90 days before semen collection had a significantly inverse association with sperm motility.Specifically,a 1 ℃ increase in HNE was associated with decreased sperm progressive motility of 0.0090(95% confidence interval[CI]:–0.0147,–0.0033) and decreased total motility of 0.0094(95% CI:–0.0160,–0.0029).HND was significantly associated with reduced sperm progressive motility and total motility of 0.0021(95% CI:–0.0040,–0.0003) and 0.0023(95% CI:–0.0043,–0.0002),respectively.Consistent results were observed at different temperature thresholds on hot nights.Conclusion Our findings highlight the need to mitigate nocturnal heat exposure during spermatogenesis to maintain optimal semen quality.
文摘Background: Pancreatic cancer is one of the most lethal malignancies, with postoperative recurrence severely affecting patient survival and prognosis. This study aims to develop and validate a clinical prediction model for postoperative recurrence in pancreatic cancer patients, incorporating multiple preoperative, intraoperative, and postoperative factors to assist clinical decision-making. Methods: A retrospective study was conducted on 216 patients who underwent surgical treatment for pancreatic malignancy at the First Affiliated Hospital of Chongqing Medical University between January 2015 and January 2023. An independent external validation cohort of 76 patients from the Second Affiliated Hospital of Chongqing Medical University was used to validate the model. Seven independent risk factors for postoperative recurrence were identified through univariate and multivariate Cox regression analyses. The model’s performance was evaluated using the concordance index (C-index) and ROC curves, and its accuracy and clinical value were assessed using calibration curves and decision curve analysis (DCA). Results: The predictive model demonstrated good discriminatory power, with a C-index of 0.72 in the training cohort and 0.66 in the validation cohort. The ROC curves for predicting recurrence at 3, 6, and 12 months postoperatively showed AUC values ranging from 0.72 to 0.83, indicating strong predictive value. Calibration curves and DCA confirmed the model’s accuracy and clinical utility. Conclusion: This study successfully developed and validated a clinical prediction model that incorporates seven independent risk factors for postoperative recurrence in pancreatic cancer. The model provides a useful tool for predicting recurrence risk, aiding in the identification of high-risk patients, and informing clinical decision-making.

文摘At the end of 2022,the adjustment of the coronavirus disease 2019(COVID-19)pandemic control policy in China resulted in alarge-scale increase in public infection.To compare the fertility parameters of male patients before and after the adjustments ofthe COVID-19 pandemic control policy in China,we collected data on patients’medical histories and laboratory examinations ontheir first visits between June 2022 and March 2023 in five different hospitals.Data were divided into five groups according tothe timeline of the policy adjustment.The data we collected from male patients included semen quality and serum reproductivehormone levels,and intergroup comparisons were made using the Mann–Whitney U and Chi-square tests.In total,16784 casesunderwent regular semen analysis,11180 had sperm morphology assessments,and 7200 had reproductive hormone analyses.Thedata showed declining trends in semen volume,sperm motility,and the progressive sperm motility rate after the policy adjustment.Subgroup comparison revealed an initial decrease and gradual recovery in progressive motility rate.Sperm morphology analysisshowed increased neck and tail abnormalities after the policy adjustment.No significant change in hormone levels was observed.Following the adjustment of the COVID-19 prevention policy in China,a decline in sperm motility and morphology was observed.This trend may gradually recover over 2 months.After the policy adjustment,reproductive hormone levels were relatively stablethroughout,except for an increase in luteinizing hormone(LH).These changes in semen parameters suggest that the policyadjustment had a short-to medium-term impact on male reproductive function.

文摘In ophthalmology,the quality of fundus images is critical for accurate diagnosis,both in clinical practice and in artificial intelligence(AI)-assisted diagnostics.Despite the broad view provided by ultrawide-field(UWF)imaging,pseudocolor images may conceal critical lesions necessary for precise diagnosis.To address this,we introduce UWF-Net,a sophisticated image enhancement algorithm that takes disease characteristics into consideration.Using the Fudan University ultra-wide-field image(FDUWI)dataset,which includes 11294 Optos pseudocolor and 2415 Zeiss true-color UWF images,each of which is rigorously annotated,UWF-Net combines global style modeling with feature-level lesion enhancement.Pathological consistency loss is also applied to maintain fundus feature integrity,significantly improving image quality.Quantitative and qualitative evaluations demonstrated that UWF-Net outperforms existing methods such as contrast limited adaptive histogram equalization(CLAHE)and structure and illumination constrained generative adversarial network(StillGAN),delivering superior retinal image quality,higher quality scores,and preserved feature details after enhancement.In disease classification tasks,images enhanced by UWF-Net showed notable improvements when processed with existing classification systems over those enhanced by StillGAN,demonstrating a 4.62%increase in sensitivity(SEN)and a 3.97%increase in accuracy(ACC).In a multicenter clinical setting,UWF-Net-enhanced images were preferred by ophthalmologic technicians and doctors,and yielded a significant reduction in diagnostic time((13.17±8.40)s for UWF-Net enhanced images vs(19.54±12.40)s for original images)and an increase in diagnostic accuracy(87.71%for UWF-Net enhanced images vs 80.40%for original images).Our research verifies that UWF-Net markedly improves the quality of UWF imaging,facilitating better clinical outcomes and more reliable AI-assisted disease classification.The clinical integration of UWF-Net holds great promise for enhancing diagnostic processes and patient care in ophthalmology.
文摘BACKGROUND The incidence of Barrett’s esophagus(BE)in China is lower compared to the Western populations.Hence,studies conducted in the Chinese population has been limited.The current treatment options available for BE treatment includes argon plasma coagulation(APC),radiofrequency ablation and cryoablation,all with varying degrees of success.AIM To determine the efficacy and safety of HybridAPC in the treatment of BE.METHODS The study cohort consisted of patients with BE who underwent HybridAPC ablation treatment.These procedures were performed by seven endoscopists from different tertiary hospitals.The duration of the procedure,curative rate,complications and recurrent rate by 1-year follow-up were recorded.RESULTS Eighty individuals were enrolled for treatment from July 2017 to June 2020,comprising of 39 males and 41 females with a median age of 54 years(range,30 to 83 years).The technical success rate of HybridAPC was 100%and the overall curative rate was 98.15%.No severe complications occurred during the operation.BE cases were classified as short-segment BE and long-segment BE.Patients with short-segment BE were all considered cured without complications.Thirty-six patients completed the one-year follow-up without recurrence.Twenty-four percent had mild dysplasia which were all resolved with one post-procedural treatment.The mean duration of the procedure was 10.94±6.52 min.CONCLUSION Treatment of BE with HybridAPC was found to be a simple and quick procedure that is safe and effective during the short-term follow-up,especially in cases of short-segment BE.This technique could be considered as a feasible alternative ablation therapy for BE.

文摘AIM： To investigate prevalence of C/onorchis sinensis in patients with gastrointestinal symptoms, and the relation of the infection to hepatobiliary diseases in 26 hospitals in Korea. METHODS： Consecutive patients who had been admitted to the Division of Gastroenterology with gastrointestinal symptoms were enrolled from March to April 2005. Of those who had been diagnosed with clonorchiasis, epidemiology and correlation between infection and hepatobiliary diseases were surveyed by questionnaire. RESULTS： Of 3080 patients with gastrointestinal diseases, 396 （12.9%） had clonorchiasis and 1140 patients （37.2%） had a history of eating raw freshwater fish. Of those with a history of raw freshwater fish ingestion, 238 （20.9%） patients had clonorchiasis. Cholangiocarcinoma was more prevalent in C. sinensis-infected patients than nonnfected patients [34/396 （8.6%） vs 145/2684 （5.4%）, P = 0.015]. Cholangiocarcinoma and clonorchiasis showed statistically significant positive cross-relation （P = 0.008）. Choledocholithiasis, cholecystolithiasis, cholangitis, hepatocellular carcinoma, and biliary pancreatitis did not correlate with clonorchiasis. CONCLUSION： Infection rate of clonorchiasis was still high in patients with gastrointestinal diseases in Korea, and has not decreased very much during the last two decades. Cholangiocarcinoma was related to clonorchiasis, which suggested an etiological role for the parasite.

文摘Community-acquired pneumonia(CAP) is one of the leading causes of morbidity and mortality in children worldwide.In this study,we aimed to describe the aetiology of viral infection of pediatric CAP in Chinese mainland.During November2014 to June 2016,the prospective study was conducted in 13 hospitals.The hospitalized children under 18 years old who met the criteria for CAP were enrolled.The throat swabs or nasopharyngeal aspirates(NPAs) were collected which were then screened 18 respiratory viruses using multiplex PCR assay.Viral pathogens were present in 56.6%(1539/2721) of the enrolled cases,with the detection rate of single virus in 39.8% of the cases and multiple viruses in 16.8% of the cases.The most frequently detected virus was respiratory syncytial virus(RSV)(15.2%,414/2721).The highest detection rate of virus was in <6-month-age group(70.7%,292/413).RSV,human metapneumovirus(HMPV),human parainfluenza viruses(HPIVs) and influenza B virus(Flu B) showed the similar prevalence patterns both in north and south China,but HPIVs,Flu A,human bocavirus(HBoV),human adenovirus(HAdV) and human coronaviruses(HCoVs) showed the distinct circulating patterns in north and south China.Human enterovirus/human rhinovirus(HEV/HRV)(27.6%,27/98),HBoV(18.4%,18/98),RSV(16.3%,16/98) and HMPV(14.3%,14/98) were the most commonly detected viruses in severe pneumonia cases with single virus infection.In conclusion,viral pathogens are frequently detected in pediatric CAP cases and may therefore play a vital role in the aetiology of CAP.RSV was the most important virus in hospitalized children with CAP in Chinese mainland.
文摘BACKGROUND Nigeria bears the greatest burden of diabetes prevalence in Sub-Saharan Africa. Diabetic foot ulcer (DFU) is a serious and potentially life-threatening complication of diabetes. Significant improvements in diabetic foot incidence and outcomes have been recorded in many Western countries in the past decade. However, the current burden of DFU in Nigeria is largely unknown. AIM To evaluate the patients’ profile, ulcer characteristics, associated co-morbidities and outcome of patients with DFU in Nigeria. METHODS Multicenter evaluation of diabetic foot ulcer in Nigeria was a one year multicenter observational study of patients hospitalized for DFU in six tertiary health institutions in Nigeria from March 2016 to March 2017. Demographic and diabetes information, ulcer characteristics and associated co-morbidities were assessed. Relevant laboratory and imaging studies were performed. All patients received appropriate multi-disciplinary care and were followed up until discharge or death. Outcome variables of interest were ulcer healing, lower extremity amputation (LEA), duration of hospitalization and mortality. RESULTS A total of 336 patients (55.1% male) with mean age of 55.9 ± 12.5 years were enrolled into this study. Majority (96.1%) had type 2 diabetes. Only 25.9% of the subjects had prior foot care knowledge. Most of the subjects presented late to the hospital and median (IQR) duration of ulcer at presentation was 39 (28-54) d. Ulcers were already advanced (Wagner grades ≥ 3) in 79.2% of the subjects while 76.8% of the ulcers were infected at the time of admission. The commonest comorbidities were systemic hypertension, anemia and hyperglycemic emergencies. One hundred and nineteen subjects (35.4%) suffered LEA while 10.4% left against medical advice. The median (IQR) duration of hospitalization was 52.0 (29-66) d with case fatality rate of 20.5%. CONCLUSION The burden of DFU in Nigeria is very high. The major gaps include low level of foot care knowledge among diabetic patients, overdependence on self-medication and unorthodox medicine following development of foot ulceration, late hospital presentation, and high amputation and mortality rates. Extensive foot care education within the framework of a multi-disciplinary foot care team is highly desirable.

文摘Human umbilical cord mesenchymal stem cells(hUC-MSCs)support revascularization,inhibition of inflammation,regulation of apoptosis,and promotion of the release of beneficial factors.Thus,they are regarded as a promising candidate for the treatment of intractable spinal cord injury(SCI).Clinical studies on patients with early chronic SCI(from 2 months to 1 year post-injury),which is clinically common,are rare;therefore,we will conduct a prospective,multicenter,randomized,placebo-controlled,single-blinded clinical trial at the Third Affiliated Hospital of Sun Yat-sen University,West China Hospital of Sichuan University,and Shanghai East Hospital,Tongji University School of Medicine,China.The trial plans to recruit 66 early chronic SCI patients.Eligible patients will undergo randomization at a 2:1 ratio to two arms:the observation group and the control group.Subjects in the observation group will receive four intrathecal transplantations of stem cells,with a dosage of 1×106/kg,at one calendar month intervals.Subjects in the control group will receive intrathecal administrations of 10 mL sterile normal saline in place of the stem cell transplantations.Clinical safety will be assessed by the analysis of adverse events and laboratory tests.The American Spinal Injury Association(ASIA)total score will be the primary efficacy endpoint,and the secondary efficacy outcomes will be the following:ASIA impairment scale,International Association of Neural Restoration-Spinal Cord Injury Functional Rating Scale,muscle tension,electromyogram,cortical motor and cortical sensory evoked potentials,residual urine volume,magnetic resonance imaging–diffusion tensor imaging,T cell subtypes in serum,neurotrophic factors and inflammatory factors in both serum and cerebrospinal fluid.All evaluations will be performed at 1,3,6,and 12 months following the final intrathecal administration.During the entire study procedure,all adverse events will be reported as soon as they are noted.This trial is designed to evaluate the clinical safety and efficacy of subarachnoid transplantation of hUC-MSCs to treat early chronic SCI.Moreover,it will establish whether cytotherapy can ameliorate local hostile microenvironments,promote tracking fiber regeneration,and strengthen spinal conduction ability,thus improving overall motor,sensory,and micturition/defecation function in patients with early chronic SCI.This study was approved by the Stem Cell Research Ethics Committee of the Third Affiliated Hospital of Sun Yat-sen University,China(approval No.[2018]-02)on March 30,2018,and was registered with ClinicalTrials.gov(registration No.NCT03521323)on April 12,2018.The revised trial protocol(protocol version 4.0)was approved by the Stem Cell Research Ethics Committee of the Third Affiliated Hospital of Sun Yat-sen University,China(approval No.[2019]-10)on February 25,2019,and released on ClinicalTrials.gov on April 29,2019.
文摘OBJECTIVE: To evaluate the efficacy of integrated Traditional Chinese Medicine-Western Medicine(TCM-WM) in the treatment of acute onset pulmonary heart disease(PHD).METHODS: A total of 240 patients met the inclusion criteria and were enrolled. These inpatients were divided into group A(treatment group) and B(control group) in order of admission according to the principles of randomization and control. The research was performed simultaneously in three hospitals. Two groups were given basic treatment that included: controlled oxygen therapy, active and effective anti-infection, maintaining airway patency,correcting O_2 deficiency and CO_2 retention, correcting acid-base imbalance and electrolyte disturbance, reducing pulmonary hypertension and treating right heart failure, nutritional support and treatment of complications. Group A was given basic treatment and integrated Traditional Chinese Medi-cine(TCM) differentiating therapy; group B was given basic therapy and a placebo that was similar in appearance and taste to TCM medicinal broth of pharmaceutical preparations, provided by Yibin Pharmaceutical Company(Yibin, China, Wuliangye Group).RESULTS: The mortality in the treatment group decreased by 4.98% compared with the control group. The treatment group reported improved ventilation, corrected hypoxemia, improved nutritional status and promoted digestive functions. It also significantly improved the patient's self-life skills, improved the patient's quality of life and could shorten the length of hospital stay.CONCLUSION: Comprehensive integrated TCMWM treatment showed good clinical efficacy toward the acute onset period of PHD patients.

文摘OBJECTIVE: To evaluate the effect of ZiYin Xiehuo granules(ZYXH) and Zishen Qinggan granules(ZSQG) on partial precocious puberty(PPP).METHODS: This was a multicenter, randomized, single-blind, positive-controlled trial. A total of 143 pa-tients were assigned to either the ZYXH group or the ZSQG group using a random number table. The ZYXH group received ZYXH three times daily for 6 months and the ZSQG group received ZSQG three times daily for 6 months. Mammary nucleus diameter; the results of uterus, ovarian, and maximum follicle measures; and Chinese medicine symptom pattern scores were compared at baseline and after 3 months and 6 months of treatment.RESULTS: After 3 months' treatment, there were no significant differences between the two groups in mammary nucleus index changes(left 3.4 ± 3.1 vs3.5 ± 3.1, P = 0.790; right 3.0 ± 2.9 vs 3.6 ± 3.0, P =0.719). The uterine volume in the ZYXH group was smaller than that in the ZSQG group(2.1 ± 1.6 vs2.6 ± 2.2, P = 0.006). There were no significant between-group differences in ovarian volume and maximum follicular diameter on either side(ovarian volume: left 1.2 ± 0.7 vs 1.3 ± 0.6, P = 0.8; right1.2 ± 0.7 vs 1.4 ± 1.1, P = 0.984; maximum follicular diameter: left 3.9 ± 1.7 vs 3.5 ± 2.2, P = 0.158; right3.5 ± 1.7 vs 3.9 ± 2.1, P = 0.314).CONCLUSION: ZYXH granules and ZSQG granules both affected the size of the mammary nucleus in girls with PPP, and improved Chinese medicine symptom patterns. ZYXH granules showed slight advantages over ZSQG granules in terms of the decrease in the size of the uterus, ovaries, and ovarian follicles.

文摘Objective:Evidence on the prognostic value of autologous stem cell transplantation(ASCT)and minimal residual disease(MRD)dynamics of patients with newly diagnosed multiple myeloma(NDMM)in China is limited.Our objective in the current study was to understand the current care paradigm and outcomes of these patients.Methods:This longitudinal cohort study used historical data from three top-tier hematologic disease care hospitals that contributed to the National Longitudinal Cohort of Hematological Diseases-Multiple Myeloma.Treatment regimens[proteasome inhibitor(PI)-,immunomodulatory drug(IMiD)-,PI+IMiD-based,and conventional],post-induction response,ASCT and MRD status,and survival outcomes[progression-free survival(PFS)and overall survival(OS)]were evaluated.Results:In total,454 patients with NDMM were included(median age,57 years;59.0%males)with a median follow-up of 58.7 months.The overall response rate was 91.0%,83.9%,90.6%,and 60.9%for PI-,IMiD-,PI+IMiD-based,and conventional regimens,respectively.Patients with ASCT during first-line therapy(26.2%)had a longer PFS and OS than patients who did not receive ASCT[median PFS,42.9 vs.21.2 months,P<0.001;median OS,not reached(NR)vs.65.8 months,P<0.001].The median OS was NR,71.5,and 56.6 months among patients with sustained MRD negativity,loss of MRD negativity,and persistent MRD,respectively(P<0.001).Multivariate analysis revealed that the lactic dehydrogenase level,International Staging System stage,extra-medullary disease,and upfront ASCT were independent factors in predicting OS among NDMM patients.Conclusions:Our study showed that novel agent-based regimens,first-line ASCT,and sustained MRD negativity were associated with a superior outcome for patients with NDMM in China(Identifier:NCT04645199).
