Objective To explore the characteristics of clinical symptoms and serum brain-derived neurotrophic factor(BDNF)level between depressive patients with and without attempted suicide behavior.Methods Serum BDNF level in depressive patients with(n=36)and without(n=55)attempted suicide behavior were assayed by ELISA,the severity of depression was measured by Hamilton rating scale for depression(HAMD).Results HAMD24 total scores(t=3.632,P=0.000),cognitive disturbance(t=-2.339,P=0.019)and hopelessness factor scores(t=-2.812,P=0.005)in depressive patients with attempted suicide behavior were significantly higher than those in depressive patients without attempted suicide behavior.There were no significant differences of anxiety/somatization,body weight,diurnal variation,psychomotric inhibition and sleeping disturbance fator scores between two groups(P＞0.05).The serum BDNF level in depressive patients with attempted suicide behavior was significantly lower than that in depressive patients without attempted suicide behavior(t=-2.122,P=0.037).There was no significant difference of serum BDNF level between male and female patients(P＞0.05).Conclusion There were certain characteristics on clinical symptoms of depressive patients with attempted suicide behavior.The low serum BDNF level might play an important role in the risk of suicide in depressive patients.

Objective To discuss the major complications of urologic laparoscopic surgery.Methods From January 2004 to May 2012,2 250 urologic laparoscopic surgical procedures were performed in our institute,including radical nephrectomies (690 cases),partial nephrectomies (285 cases),simple nephrectomies (126 cases),nephrouretectomies (270 cases),renal cyst operations (281 cases),adrenalectomies (310 cases),pyeloplasties (93 cases),ureterolithotomies (48 cases),radical prostatectomies (43 cases),radical cystectomies (49 cases),donor nephrectomies (50 cases) and retroperitoneal lymph node dissection (5 cases).Medical records of each procedure were retrospectively evaluated.Intraoperative and postoperative complications were graded according to the Satava and Clavien classifications,respectively.Major complications were defined as Satava grade Ⅱ or higher,and Clavien grade Ⅲ or higher.Results Among the 2 250 laparoscopic procedures,53 major complications occurred,resulting in a major complication rate of 2.36％.Major intraoperative and postoperative complication rates were 1.16％ (26 cases) and 1.20％ (27 cases),respectively.Vascular injuries were the most common intraoperative complications (58％) while the proportion of visceral injury was the second as 42％.The most common postoperative complication was bleeding (19 cases).Among them,3 cases died of multiple organ failure after second operations.Other major postoperative complications included wound infection (2 cases),urine leakage (1 case),adrenal crisis (1 case),ileus (2 cases) and incisional hernia (Ⅰ case) and 1 death caused by pulmonary embolism.Conclusion Major complications,including death,may occur at any stages during the urologic laparoscopic surgery.

Objective To explore the serum levels of brain-derived neurotrophic factor in patients with depression and their correlation with age,gender,age of onset,illness course,depressive severity.Methods Serum BDNF levels in 91 depressive patients and 36 healthy controls were assayed by the ELISA method .The clinical char-acteristics were assessed by the Hamilton Rating Scale for Depression ( HAMD) .Results The serum BDNF levels in depressive patients were (24.38 ±6.27)μg/L,which was significantly lower than (31.44 ±10.72)μg/L in controls (t=3.708,P <0.01) and were unrelated to age,gender,age of onset,illness course,depressive severity (r =-0.034,t=0.068,r =-0.025,0.026, -0.076,P >0.05).Conclusion Serum BDNF levels in depressive patients was decreased and low levels of BDNF in serum may be a state characteristic for depression .

Enhancement of health management capability and resource utilization efficiency of hospitals has become an imperative need to deepen the healthcare reform. The high-value consumables are subject to point-to-point accurate tracking based on code scan, relying on the hospital′s WeChat official account for WeChat-based management. The WeChat platform enables the system to automatically push the preset procurement plan to the mobile terminal of the managers via the low-inventory alarm at the departments. On the other hand, vendors can use their own mobile terminals to receive in time the plans, query product inventory, and last month invoicing information. These measures facilitate the hospital management on high-value consumables.

Objective To explore the relationship between serum silent information regulator 2 related en-zyme(SIRT)3,SIRT6,and sepsis complicated with acute respiratory distress syndrome(ARDS)and progno-sis.Methods Sixty-eight patients with sepsis complicated with ARDS admitted to the Baoding First Central Hospital from March 2020 to February 2022 were selected as the study objects,and were divided into mild group,moderate group and severe group according to the criteria of mild,moderate and severe ARDS.Accord-ing to the prognosis within 28 days,the patients were divided into survival group and death group.The levels of serum SIRT3 and SIRT6 were detected by enzyme-linked immunosorbent assay.The sequential organ fail-ure assessment(SOFA)scores,acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)scores,the levels of serum SIRT3 and SIRT6 in each group were compared.The clinical data of patients were collected,the influencing factors of mortality in patients with sepsis complicated with ARDS was analyzed by univariate and multivariate Logistic regression.The predictive value of serum SIRT3 and SIRT6 of mortality in patients with sepsis complicated with ARDS was analyzed by receiver operating characteristic(ROC)curve.Results The levels of serum SIRT3 and SIRT6 in moderate group and severe group were lower than those in mild group,the scores of SOFA and APACHE Ⅱ were higher than those in mild group,the levels of serum SIRT3 and SIRT6 in severe group were lower than those in moderate group,and the scores of SOFA and APACHE Ⅱwere higher than those in moderate group,with statistical significance(P＜0.05).There were statistically significant differences in age,mechanical ventilation time,lactate,arterial oxygenation index[arterial partial pressure of oxygen(PaO2)/inhaled oxygen concentration(FiO2)],C reactive protein(CRP),interleukin(IL)-6,SIRT3,SIRT6,SOFA score and APACHE Ⅱ score between the two groups(P＜0.05).Longer mechanical ventilation time,higher lactic acid,higher CRP,higher IL-6,higher SOFA score and higher APACHE Ⅱ score were all risk factors for death in sepsis complicated with ARDS within 28 days,while larger PaO2/FiO2,high-er SIRT3 and higher SIRT6 were protective factors(P＜0.05).ROC curve results showed that the area under the curve and 95％CI of serum SIRT3,SIRT6 levels,SOFA score and APACHE Ⅱ score were 0.706(0.493-0.922),0.722(0.497-0.954),0.753(0.570-0.922),0.710(0.442-0.952)and 0.872(0.761-0.976),respectively when applied alone and in combination.Conclusion Serum SIRT3 and SIRT6 levels are decreased in patients with sepsis complicated with ARDS,and the lower the serum SIRT3 and SIRT6 levels are as the disease worsens,the two can help predict the prognosis of patients with sepsis complicated with ARDS.

Objective:To analyze the feasibility, safety and clinical efficacy of laparoscopic side-to-side jejunoileal anastomosis in the treatment of non-obese type 2 diabetes patients (BMI≤32.5 kg/m 2). Methods:The clinical data of 135 patients who underwent laparoscopic side-to-side jejunoileal anastomosis at our hospital from Jan 2018 to Oct 2018 were retrospectively analyzed. They were followed up for 12 months until the end of Oct 2019. SPSS software was used to compare patients′ fasting blood glucose, glycosylated hemoglobin, c-peptide, insulin, body weight, BMI with the values after 12 months of the surgery, and then evaluate factors affecting the prognosis.Results:135 patients successfully completed laparoscopic side-to-side jejunoileal anastomosis without conversion to open surgery. After 12 months of the operation, the patients′ fasting blood glucose was (5.80±0.18)mmol/L, glycosylated hemoglobin was 5.9%±0.4%, fasting c-peptide was(1.32±0.21) nmol/L, and fasting insulin was (42±54) mU/L ( t=10.654, 12.657, 11.214, 10.698, all P<0.05). The body weight was (72.4±9.9)kg, BMI was( 25.6±2.8)kg/m 2, and the difference was not statistically significant ( t=7.658, 6.958, P>0.05). In patients with preoperative glycosylated hemoglobin controlled below 8% and the duration of T2DM less than 10 years, the chances being cured was better than that of those with glycosylated hemoglobin>8% and the medical history >10 years. Conclusion:Laparoscopic side-to-side jejunoileal anastomosis in the treatment of non-obese type 2 diabetes is effective, safe and reliable.

Objective:To observe the postoperative complications and revision rates of robot arm-assisted unicompartment arthroplasty by means of a meta-analysis.Methods:Relevant databases including Cochrane Library, PubMed, EMBASE, Wanfang, VIP, CNKI, and Web of Science were searched by computer for high-quality studies on complications and revision rates after robot arm-assisted unicompartment arthroplasty in both English and Chinese from the database establishment date to March 2021. The quality of the studies retrieved was evaluated. Relevant data including postoperative complications, infection, pain, prosthesis loosening, and revision were extracted for a meta-analysis using STATA 15.0 software.Results:A total of 16 studies were included, including one randomized controlled study, 6 case-control studies and 9 cohort studies. By the methodological index for non-randomized studies (MINORS), 7 studies scored 14 points, 3 studies 13 points, one study 12 points, 4 studies 11 points, and one study 10 points. Meta analysis showed that the total rate of complications was 2% (95% CI: 1%to 4%) . Three studies used NAVIO robot, 7 studies MAKO robot, one study NAVIO and MAKO robots, and one study Acrobot robot. Since just one study used Acrobot robot, only MAKO and NAVIO robots were included for the subgroup analysis which showed that the postoperative complication rates for NAVIO and MAKO robots were 4.0% (95% CI: -2% to 10%) and 3% (95% CI: 1% to 5%) , respectively. The incidence of postoperative pain was 0.2% (95% CI: 0.1% to 0.3%), the incidence of postoperative infection 0.5% (95% CI: 0.3% to 0.8%), the incidence of postoperative prosthesis loosening 0.5% (95% CI: 0.3% to 0.8%), and the revision rate 2% (95% CI: 1% to 2%). According to the subgroup analysis of NAVIO and MAKO robots, their revision rates were 4% (95% CI: 2% to 7%) and 2% (95% CI: 1% to 2%), respectively. Conclusion:The clinical efficacy of robot arm-assisted unicompartment arthroplasty is good, for the complications in the patients are limited and the long-term survival rate of the prosthesis is excellent.
