Minimally invasive intracranial hematoma drainage was performed on the minimally invasive group. Bone flap decompression or small bone window craniotomy were used in the routine group. Tumor necrosis factorα (TNF-α), interleukin-6 (IL-6), high sensitive C reactive protein (hs-CRP) and serum protein (SF), serum substance P (SP) in the 2 groups were detected before treatment and 2 weeks after treatment.Results: The comparison of TNF-α, IL-6, hs-CRP, SP, and SF in the two groups before treatment was not statistically significant (P>0.05). TNF-α, IL-6, hs-CRP and SF in both groups after treatment significantly decreased, compared with that before treatment (P<0.01,P<0.05). TNF-α, IL-6, and SF in minimally invasive group decreased more significantly than that in routine group (P<0.01);The comparison of SP in the two groups after treatment significantly increased compared with that before treatment (P<0.01,P<0.05). SP in minimally invasive group increased more significantly than that in routine group (P<0.05).Conclusions:Compared with bone flap decompression or small bone window craniotomy, minimally invasive intracranial hematoma drainage can inhibit inflammatory reaction, reduce the degree of nerve damage and alleviate clinical symptoms more effectively.展开更多

Methods: According to random data table method, a total of 120 patients with hypertensive cerebral hemorrhage from September 2016 to May 2017 were divided into observation group and the control group, 60 cases in each group. The control group was treated with conventional treatment;on the basis of conventional treatment, the observation group underwent minimally invasive evacuation of intracranial hematoma. The levels of serum SF, SP, vascular endothelial function and inflammatory factors changes were compared between the two groups before and after the treatment. Results: Before treatment, the levels of serum SP, SF, NO, ET-1, hs-CRP, IL-6, TNF-α in the two groups were not statistically significant. The levels of hs-CRP, IL-6, TNF-α, SF, ET-1 after treatment in two groups were significantly lower than those in the same group before treatment, and the observation group levels were significantly lower than those in the control group;the levels of SP, NO in the two groups after treatment were significantly higher than before treatment, and the observation group was higher than that the control group with significant difference. Conclusion: The minimally invasive intracranial hematoma evacuation for patients with HICH can effectively improve the levels of SP, SF, inflammatory factors and vascular endothelial function, which is helpful to relieve cerebral edema and lower intracranial pressure, and improve the quality of treatment.展开更多

Effective management performance of municipal solid waste management underscores the interdisciplinarity strategies. Such knowledge and skills are paramount to uncover the sources of waste generation as well as means of waste storage, collection, recycling, transportation, handling/treatment, disposal, and monitoring. This study was conducted in Dar es Salaam city. Driven by the curiosity model of the solid waste minimization performance at source, study data was collected using focus group discussion techniques to ward-level local government officers, which was triangulated with literature and documentary review. The main themes of the FGD were situational factors (SFA) and local government by-laws (LGBY). In the FGD session, sub-themes of SFA tricked to understand how MSW minimization is related to the presence and effect of services such as land use planning, availability of landfills, solid waste transfer stations, material recovery facilities, incinerators, solid waste collection bins, solid waste trucks, solid waste management budget and solid waste collection agents. Similarly, FGD on LGBY was extended by sub-themes such as contents of the by-law, community awareness of the by-law, and by-law enforcement mechanisms. While data preparation applied an analytical hierarchy process, data analysis applied an ordinary least square (OLS) regression model for sub-criteria that explain SFA and LGBY;and OLS standard residues as variables into geographically weighted regression with a resolution of 241 × 241 meter in ArcMap v10.5. Results showed that situational factors and local government by-laws have a strong relationship with the rate of minimizing solid waste dumping in water bodies (local R square = 0.94).展开更多

In addition, the traditional outlier detection method does not consider the frequency of subsets occurrence, thus, the detected outliers do not fit the definition of outliers (i.e., rarely appearing). The pattern mining-based outlier detection approaches have solved this problem, but the importance of each pattern is not taken into account in outlier detection process, so the detected outliers cannot truly reflect some actual situation. Aimed at these problems, a two-phase minimal weighted rare pattern mining-based outlier detection approach, called MWRPM-Outlier, is proposed to effectively detect outliers on the weight data stream. In particular, a method called MWRPM is proposed in the pattern mining phase to fast mine the minimal weighted rare patterns, and then two deviation factors are defined in outlier detection phase to measure the abnormal degree of each transaction on the weight data stream. Experimental results show that the proposed MWRPM-Outlier approach has excellent performance in outlier detection and MWRPM approach outperforms in weighted rare pattern mining.展开更多

Laparoscopic approach has theadvantage of minimally invasive. The risk factors influencing perioperativecomplications of laparoscopic surgery are rarely discussed.AIMTo investigate the risk factors for perioperative complications in laparoscopicsurgeries of retrorectal cystic lesions.METHODSWe retrospectively reviewed the medical records of patients who underwentlaparoscopic excision of retrorectal cystic lesions between August 2012 and May2020 at our hospital. All surgeries were performed in the general surgerydepartment. Patients were divided into groups based on the lesion location anddiameter. We analysed the risk factors like type 2 diabetes mellitus, hypertension,the history of abdominal surgery, previous treatment, clinical manifestation,operation duration, blood loss, perioperative complications, and readmission ratewithin 90 d retrospectively.RESULTSSevere perioperative complications occurred in seven patients. Prophylactictransverse colostomy was performed in four patients with suspected rectal injury.Two patients underwent puncture drainage due to postoperative pelvic infection.One patient underwent debridement in the operating room due to incisioninfection. The massive-lesion group had a significantly longer surgery duration,higher blood loss, higher incidence of perioperative complications, and higherreadmission rate within 90 d (P < 0.05). Univariate analysis, multivariate analysis,and logistic regression showed that lesion diameter was an independent riskfactor for the development of perioperative complications in patients whounderwent laparoscopic excision of retrorectal cystic lesions.CONCLUSIONThe diameter of the lesion is an independent risk factor for perioperative complicationsin patients who undergo laparoscopic excision of retrorectal cystic lesions.The location of the lesion was not a determining factor of the surgical approach.Laparoscopic surgery is minimally invasive, high-resolution, and flexible, and itsuse in retrorectal cystic lesions is safe and feasible, also for lesions below the S3level.展开更多

文摘Objective:Our previous studies have indicated potentially higher proliferative activity of tumor cells in Chinese patients with mantle-cell lymphoma(MCL)than those in Western.Given the success and tolerability of R-DA-EDOCH immunochemotherapy in treating aggressive B-cell lymphomas,we designed a prospective,phase 3 trial to explore the efficacy and safety of alternating R-DA-EDOCH/R-DHAP induction therapy for young patients with newly diagnosed MCL.The primary endpoint was the complete remission rate(CRR)at the end of induction(EOI).Methods:A total of 55 patients were enrolled.The CRR at the EOI was 89.1%[95%confidence interval(CI)78%±96%],and the overall response rate was 98.1%(95%CI 90%±100%).Most patients with bone marrow involvement quickly attained minimal residual disease(MRD)negative status,with a 95.7%rate at the EOI.Results:The 3-year progression-free survival(PFS)and overall survival rates were 66.3%and 83.2%,respectively.No patients discontinued treatment because of adverse events.Univariate analysis identified pathologic morphology and TP53 mutations as risk factors for PFS.However,high tumor proliferative activity and certain cytogenetic abnormalities showed no significant adverse prognostic significance.Conclusions:Intensive therapy based on a high cytarabine dose and continuously administered EDOCH achieved a high MRDnegative rate and provides an optional induction choice for young patients with MCL with high-risk factors.
文摘Perioperative morbidity of esophagectomy significantly affects the surgical outcome,like any major gastrointestinal procedure.Despite introduction of minimally invasive esophagectomy,the morbidity is still close to 30%-40%.The common complications following esophagectomy are pulmonary infections,cardiac events,anastomotic leakage,bleeding,chylous leak,and recurrent laryngeal nerve palsy which in turn lead to longer hospital stay,increased treatment cost and poor quality of life.A nomographic model comprising preoperative(patient,disease and treatment related)and intraoperative factors in combination with Artificial Intelligence may accurately identify the patients at higher risk of morbidity.This will aid in optimizing the modifiable risk factors preoperatively,and closely monitor these patients post operatively for early identification of complications and to initiate early corrective measures to improve the surgical outcome.
文摘目的探讨微创甲状腺手术对甲状腺乳头状癌(papillary thyroid carcinoma,PTC)患者术后甲状旁腺功能恢复的影响,明确恢复时间及其相关影响因素。方法采用队列研究,选取2023年1月至2024年1月在新乡医学院第一附属医院接受手术治疗的110例PTC患者,分为微创手术组(55例)和传统开放手术组(55例)。收集术前甲状腺及甲状旁腺功能指标、术中甲状旁腺保护情况、手术时间、术后血清钙和甲状旁腺激素(parathyroid hormone,PTH)水平、术后恢复时间、低钙血症发生率、住院时间和术后疼痛评分。通过Cox回归模型分析影响恢复的因素,并对两组术后指标进行比较。结果微创手术组的甲状旁腺功能恢复时间显著短于传统组[10(8~12)d vs 17(15~21)d,P<0.001]。术后24和72 h,微创组的血清钙及PTH水平均显著高于传统组(P<0.001),低钙血症发生率明显低于传统组(15.8%vs 32.5%,P=0.005)。Cox回归分析显示,手术方式(HR=0.55,95%CI:0.33~0.91,P=0.021)、甲状旁腺保护(HR=0.58,95%CI:0.35~0.95,P=0.037)、术后早期血清钙(HR=1.32,95%CI:1.10~1.60,P=0.002)及手术时间(HR=1.12,95%CI:1.05~1.20,P=0.001)为独立影响因素。此外,微创组的住院时间(5.2 d vs 7.8 d,P<0.001)和术后疼痛评分(第1 d:2.3 vs 3.7,P<0.001;第3 d:1.5 vs 2.8,P<0.001)均显著低于传统组。结论微创甲状腺手术在甲状腺乳头状癌患者的甲状旁腺功能恢复中具有显著优势,能够缩短恢复时间,减少低钙血症发生率,降低住院时间和术后疼痛。手术方式及甲状旁腺保护是恢复时间的关键因素。

文摘Recombinant tissue plasminogen activator is commonly used for hematoma evacuation in minimally invasive surgery following intracerebral hemorrhage.However,during minimally invasive surgery,recombinant tissue plasminogen activator may come into contact with brain tissue.Therefore,a thorough assessment of its safety is required.In this study,we established a mouse model of intracerebral hemorrhage induced by type VII collagenase.We observed that the administration of recombinant tissue plasminogen activator without hematoma aspiration significantly improved the neurological function of mice with intracerebral hemorrhage,reduced pathological damage,and lowered the levels of apoptosis and autophagy in the tissue surrounding the hematoma.In an in vitro model of intracerebral hemorrhage using primary cortical neurons induced by hemin,the administration of recombinant tissue plasminogen activator suppressed neuronal apoptosis,autophagy,and endoplasmic reticulum stress.Transcriptome sequencing analysis revealed that recombinant tissue plasminogen activator upregulated the phosphoinositide 3-kinase/RAC-alpha serine/threonine-protein kinase/mammalian target of rapamycin pathway in neurons.Moreover,the phosphoinositide 3-kinase inhibitor LY294002 abrogated the neuroprotective effects of recombinant tissue plasminogen activator in inhibiting excessive apoptosis,autophagy,and endoplasmic reticulum stress.Furthermore,to specify the domain of recombinant tissue plasminogen activator responsible for its neuroprotective effects,various inhibitors were used to target distinct domains.It has been revealed that the epidermal growth factor receptor inhibitor AG-1478 reversed the effect of recombinant tissue plasminogen activator on the phosphoinositide 3-kinase/RAC-alpha serine/threonineprotein kinase/mammalian target of rapamycin pathway.These findings suggest that recombinant tissue plasminogen activator exerts a direct neuroprotective effect on neurons following intracerebral hemorrhage,possibly through activation of the phosphoinositide 3-kinase/RAC-alpha serine/threonine-protein kinase/mammalian target of rapamycin pathway.

文摘The distance-based outlier detection method detects the implied outliers by calculating the distance of the points in the dataset, but the computational complexity is particularly high when processing multidimensional datasets. In addition, the traditional outlier detection method does not consider the frequency of subsets occurrence, thus, the detected outliers do not fit the definition of outliers (i.e., rarely appearing). The pattern mining-based outlier detection approaches have solved this problem, but the importance of each pattern is not taken into account in outlier detection process, so the detected outliers cannot truly reflect some actual situation. Aimed at these problems, a two-phase minimal weighted rare pattern mining-based outlier detection approach, called MWRPM-Outlier, is proposed to effectively detect outliers on the weight data stream. In particular, a method called MWRPM is proposed in the pattern mining phase to fast mine the minimal weighted rare patterns, and then two deviation factors are defined in outlier detection phase to measure the abnormal degree of each transaction on the weight data stream. Experimental results show that the proposed MWRPM-Outlier approach has excellent performance in outlier detection and MWRPM approach outperforms in weighted rare pattern mining.

文摘AIM:To explore the efficacy of minimally invasive vitrectomy(MIV)with or without internal limiting membrane(ILM)peeling on the treatment of diabetic macular edema(DME)in proliferative diabetic retinopathy(PDR)combining with preoperative anti-vascular endothelial growth factor(anti-VEGF)injection.METHODS:Totally 132 eyes(132 patients)diagnosed PDR with DME were included between June 2015 and June 2018 in Tianjin Eye Hospital.The single MIV treatment group included 68 eyes and the MIV combined with ILM peeling group included 64 eyes.Anti-VEGF drugs were injected intravitreally 1wk before the operation and the period of follow-up was 1 to 3y.Best-corrected visual acuity(BCVA),central retinal thickness(CRT),total macular volume(TMV),macular edema(ME)severity,intraocular pressure(IOP),and complications were recorded.Prognostic factors of visual acuity following ILM peeling were analyzed.RESULTS:The BCVA was higher than preoperative values at 1,3,6,and 12mo after surgery in both groups(all P<0.05).At 6 and 12mo,the BCVA of the combined group was significantly higher than that of the MIV only group(0.52±0.23 v/s 0.64±0.29 IogMAR,P=0.011 in 6mo;0.41±0.25\/s 0.52±0.25 IogMAR,P=0.008 in 12mo).Mean CRT values postoperative were significantly lower than preoperative values in both groups from the 1^(st) month(lmo 397.65±106.18 vs 451.94±118.88 μm in MIV only group;388.88±108.68 v/s 464.36±111.53 μm in combined group;both P<0.05)and decreased gradually.The differences between the two groups were statistically significant at 3,6,and 12mo(P=0.004,0.003,0.00 respectively).The TMV was decreased from the 3^(rd) month in the single treatment group(3mo 11.14±1.66 vs 12.20±2.09 mm^(3),P<0.05).At 12mo,the proportion of eyes with edema that had CRT more than 350μm was significantly lower than before surgery(13.24%vs 77.94%in MIV only group;1.56%vs 81.25%in combined group;both P<0.05).There was no significant difference in the recurrence incidence of macular epiretinal membrane,ME,transient IOP increase,vitreous rebleeding,or traction retinal detachment between the two groups.BCVA after ILM excision was positively correlated with the CRT and ME degree before and after surgery(r=0.430,0.485,respectively;P<0.05).CONCLUSION:MIV combined with ILM peeling accelerates the absorption of ME,improves vision,reduces the postoperative CRT and TMV,and reduces the recurrence rate of postoperative ME.
文摘BACKGROUNDThe incidence of retrorectal lesions is low, and no consensus has been reachedregarding the most optimal surgical approach. Laparoscopic approach has theadvantage of minimally invasive. The risk factors influencing perioperativecomplications of laparoscopic surgery are rarely discussed.AIMTo investigate the risk factors for perioperative complications in laparoscopicsurgeries of retrorectal cystic lesions.METHODSWe retrospectively reviewed the medical records of patients who underwentlaparoscopic excision of retrorectal cystic lesions between August 2012 and May2020 at our hospital. All surgeries were performed in the general surgerydepartment. Patients were divided into groups based on the lesion location anddiameter. We analysed the risk factors like type 2 diabetes mellitus, hypertension,the history of abdominal surgery, previous treatment, clinical manifestation,operation duration, blood loss, perioperative complications, and readmission ratewithin 90 d retrospectively.RESULTSSevere perioperative complications occurred in seven patients. Prophylactictransverse colostomy was performed in four patients with suspected rectal injury.Two patients underwent puncture drainage due to postoperative pelvic infection.One patient underwent debridement in the operating room due to incisioninfection. The massive-lesion group had a significantly longer surgery duration,higher blood loss, higher incidence of perioperative complications, and higherreadmission rate within 90 d (P < 0.05). Univariate analysis, multivariate analysis,and logistic regression showed that lesion diameter was an independent riskfactor for the development of perioperative complications in patients whounderwent laparoscopic excision of retrorectal cystic lesions.CONCLUSIONThe diameter of the lesion is an independent risk factor for perioperative complicationsin patients who undergo laparoscopic excision of retrorectal cystic lesions.The location of the lesion was not a determining factor of the surgical approach.Laparoscopic surgery is minimally invasive, high-resolution, and flexible, and itsuse in retrorectal cystic lesions is safe and feasible, also for lesions below the S3level.
