OBJECTIVE To calculate the cost of centralized dispensing of four categories of drugs （ordinary drugs， antibacterial drugs， hazardous drugs， and parenteral nutrition solutions） in pharmacy intravenous admixture service （PIVAS）， and provide reference for setting charging standards for relevant departments. METHODS The operating costs of PIVAS in 12 medical institutions from Shaanxi province were collected through questionnaire survey， including labor costs， medical and health material costs， fixed asset depreciation and repair costs， water and electricity costs， and management costs. The operation time allocation coefficient method and workload allocation coefficient method were comprehensively used to allocate the above costs， and the unit preparation costs of four categories of drugs were calculated. RESULTS The average annual total costs of dispensing ordinary drugs， antibacterial drugs， hazardous drugs， and parenteral nutrition solutions in Shaanxi province were （2 195 900.25±1 680 893.73） yuan， （746 341.59±725 839.39） yuan， （331 420.15±183 258.83） yuan， and （330 322.68±277 281.70） yuan， respectively， with labor costs accounting for the highest proportion， averaging 85.49%. The costs of dispensing a set of ordinary drugs， antibacterial drugs， and hazardous drugs were 5.89， 7.60， and 14.37 yuan， respectively； the cost of dispensing one bag of parenteral nutrition solution was 32.15 yuan （excluding the cost of disposable intravenous nutrition bags）. CONCLUSIONS The cost calculation method and data of different types of intravenous drugs obtained in this study can provide reference for relevant departments to formulate and adjust PIVAS fee standards.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

Objective:To compare the efficacy of pneumovesicoscopic Cohen and Politano-Leadbetter procedures in the treatment of vesicoureteral junction obstruction (VUJO) in children.Methods:The data of 48 children with VUJO who underwent operations in the Department of Urology, Anhui Provincial Children′s Hospital from January 2017 to December 2021 were retrospectively analyzed.According to the operation time, the patients were divided into the pneumovesicoscopic Cohen group(group C) (28 cases) and pneumovesicoscopic Politano-Leadbetter group(group P) (20 cases). The operation time, postoperative urinary catheterization duration, hematuria duration, hospitalization time, and the improvement of hydronephrosis, ureteral dilatation, and renal function after surgery were compared between the 2 groups.The enumeration data were compared by the χ2 test or Fisher′ s exact probability method.The measurement data were compared by the t-test. Results:All the 48 children were successfully operated on by the same surgeon, without conversion to open surgery.Six cases in the group C had a megaureter and underwent ureter tailoring.Two cases in the group P had calyceal and ureteral calculi, which were all removed after operation.There was a statistically significant difference in the operation time between group C and group P[(136.5±35.4) min vs.(165.8±33.2) min, t=-3.154, P=0.002]. The patients were followed up for (10.3±2.6) months after operation.There were 8 cases and 6 cases of urinary tract infection in group C and group P within 2 months after the operation, respectively.They all improved after conservative anti-infection treatment, and the infection was well controlled after removal of the D-J tube.Besides, their intravenous pyelography 6 months after operation showed that the ureter was unobstructed.In group C, 6 months after the operation, the anterior and posterior diameters of the renal pelvis [(1.62±0.54) cm vs.(2.55±1.24) cm, t=-5.027, P=0.001] and the largest diameter of the ureter [(0.95±0.27) cm vs.(1.51±0.52) cm, t=-8.495, P<0.001] were significantly decreased, compared with those before operation.However, the renal cortex thickness was increased significantly [(1.47±0.25) cm vs.(0.86±0.46) cm, t=2.028, P=0.004], and the renal function (as indicated by the diuretic nephrogram) was notably improved [(46.27±2.16)% vs.(41.83±3.04)%, t=1.647, P=0.030]. In group P, 6 months after operation, the anterior and posterior diameters of the renal pelvis[(1.48±0.82) cm vs.(2.68±1.41) cm, t=-2.740, P=0.003] and the maximum diameter of the ureter [(1.05±0.46) cm vs.(1.36±0.27) cm, t=-1.635, P=0.040] were significantly smaller than those before operation.However, the renal cortical thickness was increased [(1.38±0.33) cm vs.(0.74±0.39) cm, t=9.073, P<0.001], and the renal function (as indicated by the diuretic nephrogram) was significantly improved [(45.18±3.35)% vs.(39.55±2.49)%, t=1.277, P=0.030]. Politano-Leadbetter surgery outperformed Cohen surgery in promoting the recovery of the anterior and posterior diameters of the renal pelvis [(1.48±0.82) cm vs.(1.62±0.54) cm, t=-1.748, P=0.030]. Conclusions:Pneumovesicoscopic Politano-Leadbetter operation can establish a longer submucosal tunnel without changing the ureteral shape and opening position, having good effects in treating VUJO combined with calyceal and ureteral calculi.Pneumovesicoscopic Politano-Leadbetter operation can also better improve postoperative recovery from hydronephrosis than Cohen operation.However, the pneumovesicoscopic Politano-Leadbetter operation is more difficult and requires longer time.The surgeon should choose a reasonable operation based on his/her own experience.

Objective:To evaluate the risk of HBV recurrence after liver transplantation in patients with end-stage hepatitis B related liver disease, and to explore the indications for antiviral therapy withdrawal.Methods:The data of HBV DNA, cccDNA in liver puncture tissues and peripheral blood in 31 patients after liver transplantation was retrospectively analyzed.Results:Among the 31 patients, 15 (48%) had detectable and quantified HBV DNA in liver biopsy tissue, while their HBV related serological indicators were negative, suggesting an occult HBV infection in some patients. The study found 15 out of 19 cases who were taking Entecavir were cccDNA negative (78.9%), compared to 5 out of 12 cases (41.6%) in Lamivudine regiment ( P=0.03). Conclusions:Hidden HBV infection can be detected by amplifying cccDNA and HBV DNA in liver puncture tissue by using ddPCR. Entecavir is superior to lamivudine in the clearance of cccDNA.

Objective: To analyze the correlations between cholecystolithiasis or cholecystectomy and the risk of colorectal cancer, and make a brief summary combining with the present study. Methods: Qualified studies about the correlations between cholecystolithiasis or cholecystectomy and the risk of colorectal cancer published in English and Chinese before April 2018 were retrieved from PubMed, Cochrane Library, China National Knowledge Infrastructure(CNKI), Wan Fang Data, and VIP. Case-control and cohort studies were selected according to the inclusion and exclusion criteria and assessed by the Newcastle-Ottowa Scale, then we chose the high-quality literature to extract the data and analyze those data by RevMan 5.3 software. Publication bias was analyzed by Stata 12.1 software. Results: A total of 28 articles were finally included in the systematic review, including 23 case-control studies and 5 cohort studies. The results showed that there is a significant relationship between cholecystolithiasis and the risk of colorectal cancer(OR=1.70, 95%CI: 1.39~2.08, P<0.05)、colon cancer(OR=1.74, 95%CI: 1.36~2.23, P<0.05)、rectal cancer (OR=1.35, 95%CI: 1.02~1.80, P<0.05). The results showed a risk of colorectal cancer(OR=1.31, 95%CI: 1.14~1.51, P<0.05) and colon cancer (OR=1.20, 95%CI: 1.05~1.36, P<0.05) after cholecystectomy, but the risk is significantly less than the risk in patients with gallstone. And there is no relevance between cholecystectomy and the risk of rectal cancer(OR=0.89, 95%CI: 0.73~1.08, P>0.05). Conclusion There is a positive association between cholecystolithiasis and colorectal cancer, but cholecystectomy itself may be not the risk of rectal cancer.

Objective To investigate the value of the preoperative Child-Pugh score and albuminbilirubin (ALBI) score predicting posthepatectomy liver failure (PHLF) and prognosis of patients with hepatocellular carcinona (HCC).Methods The retrospective cohort study was conducted.The clinical data of 226 HCC patients who were admitted into the People's Hospital of Peking University between January 2010 and October 2014 were collected.After preoperative related examinations,feasibility and extent of liver resection were discussed according to patients' conditions by muhidisciplinary team,and then surgery was performed.Observation indicators:(1) surgical situations;(2) factors analysis affecting PHLF of HCC patients;(3) receiver operating characteristic (ROC) curve analysis of Child-Pugh and ALBI scores predicting PHLF;(4) follow-up and survival situations;(5) prognosis analysis of HCC patients after hepatectomy.Follow-up using outpatient examination and telephone interview was performed to detect postoperative survival up to August 2016.Measurement data with normal distribution were represented as-±s.Measurement data with skewed distribution were described as M (P25,P75).The survival curve was drawn by the Kaplan-Meier method,and the Log-rank test was used for survival analysis.The influencing factors of PHLF were analyzed using the logistic regression model.The prognostic factors were analyzed by the COX regression model.ROC analysis was used for predictive value of Child-Pugh and ALBI scores.Results (1) Surgical situations:226 patients underwent successful surgery,including 171 receiving localized liver resection (＜ 3 Couinaud hepatic segments resection) and 55 receiving extensive liver resection (≥ 3 Couinaud hepatic segments resection).Volume of intraoperative blood loss of 226 patients was 1-22 550 mL,with a median of 800 mL.Of 226 patients,89,9,4,4,3 and 1 were complicated with liver failure,pulmonary infection,bile leakage,gastrointestinal henorrhage,incision infection and infectious shock,respectively,they were cured and discharged from hospital by life-sustaining treatment and symptomatic treatment.Duration of hospital stay was 2-49 days,with a median of 12 days.(2) Factors analysis affecting PHLF of HCC patients:results of univariate analysis showed that gender,total bilirubin (TBil),albumin (Alb),prothrombin time (PT),international normalized ratio (INR),platelet (PLT),peritoneal effusion,volume of intraoperative blood loss,Child-Pugh score and ALBI score were related factors affecting PHLF of HCC patients [Odds ratio (OR) =O.490,1.077,0.763,1.613,26.342,0.990,2.458,5.052,2.875,34.570,95％ confidence interval (CI):0.248-0.971,1.030-1.127,0.699-0.833,1.248-2.087,2.722-254.936,0.985-0.995,1.386-4.361,2.467-10.347,1.807-4.576,11.674-102.376,P＜0.05].Child-Pugh score and ALBI score in the multivariate analysis were respectively analyzed using the logistic regression model for avoiding multicollinearity.Excluding TBil,Alb,PT and peritoneal effusion,logistic regression model of Child-Pugh score showed that PLT,volume of intraoperative blood loss and Child-Pugh score were independent factors affecting PHLF of HCC patients (OR=0.991,4.462,2.412,95％CI:0.986-0.996,2.090-9.527,1.479-3.934,P＜0.05).Excluding TBil and Alb,Logistic regression model of ALBI score showed that PLT,volume of intraoperative blood loss and ALBI score were independent factors affecting PHLF of HCC patients (OR=O.990,4.867,42.947,95％CI:O.984-0.995,2.088-11.346,12.409-148.637,P＜ 0.05).(3) ROC analysis of Child-Pugh and ALBI scores predicting PHLF:area under the ROC was respectively 0.652 (95％CI:0.577-0.727) in the Child-Pugh score and 0.801 (95％CI:0.741-0.861) in the ALBI score,with a statistically significant difference (Z=3.590,P＜0.05).The best critical value,sensitivity and specificity of PHLF that were predicted by ALBI score were-2.58,68.5％ and 86.9％,respectively.Further analysis showed that area under the ROC was respectively 0.642 (95％CI:0.554-0.731) in Child-Pugh score and 0.813 (95％CI:0.744-0.882) in ALBI score,excluding factors of extensive liver resection affecting PHLF,with a statistically significant difference (Z=3.407,P＜0.05).(4)Follow-up and survival situations:of 226 patients,217 were followed up for 1.3-79.5 months,with a median time of 29.5 months.During the follow-up,134 patients had survival and 92 died.(5) Prognosis analysis of HCC patients after hepatectomy:results of univariate analysis showed that Alb,PLT,alpha-fetoprotein (AFP),peritoneal effusion,tumor diameter,extent of resection,combined portal vein tumor thrombus (PVTT),combined vascular tumor thrombus and Child-Pugh score were related factors affecting prognosis of HCC patients [Hazard Ratio (HR)=0.954,1.003,2.958,1.698,1.155,1.785,2.326,3.001,1.324,95％CI:0.911-0.999,1.000-1.005,1.955-4.476,1.115-2.585,1.103-1.209,1.138-2.802,1.310-4.130,1.983-4.546,1.037-1.690,P ＜ 0.05].Excluding Alb and peritoneal effusion for avoiding multicollinearity,results of multivariate analysis showed that AFP,tumor diameter,combined vascular tumor thrombus and Child-Pugh score were independent factors affecting prognosis of HCC patients (HR =2.237,1.080,2.122,1.309,95％ CI:1.439-3.476,1.028-1.134,1.362-3.305,1.010-1.697,P＜0.05).Further analysis of Kaplan-Meier curve showed that median survival time in patients with grade A and B of Child-Pugh score were respectively 30.6 months and 25.2 months,with a statistically significant difference in survival (x2 =4.491,P＜0.05).The median survival time in patients with grade 1 and 2 of ALBI score were respectively 29.6 months and 31.0 months,with no statistically significant difference in survival (x2 =0.539,P＞0.05).Conclusion Preoperative ALBI score in predicting PHLF is superior to that of Child-Pugh score,but ALB1 score is not independent factor affecting prognosis of HCC patients.

Integrated medical education, namely medical education under the concept of integration, is an important trend in the development of global medical education, and also an important task in the re-form of medical universities and colleges in China. The integrated medical education abroad originated from Europe and America, and developed relatively well. It started late in China and was limited to integration of some subjects. At present, the reform of integrated medical education in domestic colleges and universities is still facing the problems and challenges such as lag of teaching ideas, limited content of reform, insufficient teachers' ability, difficulty to change learning habits, deviations of learning purposes, lack of integrated learning, lack of system, poor mechanism, weak guarantee and so on. In the future, we should make efforts to teach, learn and manage, give full play to the leading role of "teaching", improve the main position of"learning", and constantly improve the guarantee function of "management".

Objective To evaluate the effect of electroacupuncture on endoplasmic reticulum stress in lung tissues of rats with acute lung injury (ALI) induced by endotoxin.Methods Forty healthy pathogen-free male Sprague-Dawley rats,aged 8 weeks,weighing 180-210 g,were divided into 4 groups (n=10 each) using a random number table:control group (group C),ALI group,electroacupuncture group (group E),and electroacupuncture at non-acupoint group (group NE).Lipopolysaccharide 5 mg/kg (in 0.5 ml normal saline) was injected intravenously to establish the model of endotoxin-induced ALI.Bilateral 30 min electroacupuncture stimulation of Zusanli and Neiguan acupoints was performed with the dispersedense wave (frequency 2/15 Hz,wave length 0.2-0.6 ms,intensity 1-2 mA) once a day (time for stimulation 9:30-10:30) for 4 consecutive days before and during establishment of the model in group E.Electroacupuncture was performed with the same parameters at the points 0.5 cm lateral to the acupoints of Zusanli and Neiguan in group NE.At 6 h after lipopolysaccharide injection,the rats were sacrificed,and lungs were removed for microscopic examination and for determination of wet to dry weight ratio (W/D ratio),apoptosis in alveolar epithelial cells and expression of glucose-regulated protein 78 (GRP78) and CCAAT/enhancer-binding protein homologous protein (CHOP) and caspase-12 in lung tissues (by Western blot).The pathological changes of lungs were scored.Apoptosis index (AI) was calculated.Results Compared with group C,lung injury scores,W/D ratio and AI were significantly increased,and the expression of GRP78,CHOP and caspase-12 in lung tissues was up-regulated in the other three groups (P＜0.05).Compared with group ALI,lung injury scores,W/D ratio and AI were significantly decreased,and the expression of GRP78,CHOP and caspase-12 in lung tissues was down-regulated in group E (P＜0.05),and no significant change was found in the paramneters mentioned above in group NE (P＞0.05).Conclusion The mechanism by which electroacupuncture attenuates endotoxin-induced ALI is related to inhibition of endoplasmic reticulum stress and reduction of apoptosis in alveolar epithelial cells in rats.

OBJECTIVE: To evaluate the feasibility and efficacy of transurethral electrotomy combined with seminal vesiculoscopy ejaculatory duct dilatation in treating patients with Müllerian duct cyst. 
 METHODS: We retrospectively analyzed 12 infertile men due to Müllerian duct cyst between 2009 and 2012. They were diagnosed by semen analysis (including quantity of semen, pH and fructose), digital rectal examination, transrectal ultrasonography, magnetic resonance images and aspiration biopsy when necessary. All patients were treated by transurethral electrotomy combined with seminal vesiculoscopy ejaculatory duct dilatation and were followed up for 12 months. 
 RESULTS: A significant improvement of semen quality was achieved after surgery and the sperms could be seen. The patients' semen was analyzed for 3 times in 12 months and the results were normal. Semen volume and pure berries of the patients were increased after the operation compared with those before the operation (P<0.05). Spontaneous pregnancies were achieved in 3 patients 9-12 months after surgery. Four patients' seminal vesicle became smaller obviously.
 CONCLUSION Transurethral electrotomy combined with seminal vesiculoscopy ejaculatory duct dilatation is effective and safe for the treatment of Müllerian duct cyst accompanied with ejaculatory duct obstruction.
