Objective:To develop and validate a postoperative infection nomogram of hepatitis B-associated hepatocellular carcinoma (HCC) after hepatectomy.Methods:Clinical data of 229 patients with HCC undergoing hepatectomy at the Department of Hepatobiliary Surgery of Tianjin Third Central Hospital from January 2014 to December 2022 were retrospectively analyzed, including 174 males and 55 females, aged (58.2±11.4) years. LASSO regression analysis screened the factors associated with hepatitis B-associated HCC infection after hepatectomy, which were further incorporated into multivariate logistic regression analysis. A nomographic prediction model was established based on the results of multivariate logistic regression analysis. Concordance index (C-index), calibration curve and receiver operating characteristic (ROC) curve were used to evaluate the model, and decision curve analysis (DCA) was used to analyze the clinical applicability of the model. Internal validation of the model was performed using bootstrap method.Results:A total of nine variables were screened as factors associated with the postoperative infections using LASSO regression, including gender, smoking history, body mass index (BMI), serum level of alpha fetoprotein, resection fashion (anatomical or non-anatomical), intraoperative blood loss, surgical method (laparoscopy or open), serum level of creatinine, and postoperative biliary fistula. Multivariate logistic regression analysis showed that BMI, resection fashion, intraoperative blood loss >500 ml, and postoperative biliary fistula were risk factors for postoperative infection (all P<0.05). Based on the above risk factors, a postoperative infection nomogram of hepatitis B-associated HCC after hepatectomy was established. The C-index was 0.839 (95% CI: 0.768-0.910), and the area under ROC curve was 0.853 (95% CI: 0.795-0.912), indicating that the model had a good predictive ability. The calibration curve was basically consistent with the ideal curve. The DCA showed that the model had a good clinical applicability. Internal validation C-index was 0.829 (95% CI: 0.766-0.892). Conclusion:The nomogram based on BMI, surgical resection fashion, intraoperative blood loss >500 ml, and postoperative biliary fistula has a high predictive accuracy and can be used to predict postoperative infections after hepatectomy for HCC.

ObjectiveTo investigate the differences in the risk factors for postoperative pancreatic fistula （POPF） after pancreaticoduodenectomy （PD） between the 2005 and 2016 editions of the definition and classification standards for pancreatic fistula， and to establish a risk prediction model for pancreatic fistula based on the 2016 edition. MethodsA retrospective analysis was performed for the clinical data of 303 patients who were admitted to Tianjin Third Central Hospital and underwent PD from January 2016 to May 2022， and the patients with POPF were identified based on the new and old editions. The independent-samples t test or the non-parametric Mann-Whitney U test was used for comparison of continuous data between groups， and the chi-square test was used for comparison of categorical data between groups. The univariate and multivariate logistic regression analyses were used to investigate the differences in the risk factors for pancreatic fistula after PD between the two editions； a risk prediction model was established for POPF based on the 2016 edition， and the receiver operating characteristic curve was used to invesitgate the accuracy of this model in predicting POPF and perform model validation. ResultsAccording to the 2005 edition， the univariate analysis showed that the diameter of the main pancreatic duct （χ²=31.641， P<0.001）， main pancreatic duct index （χ²=52.777， P<0.001）， portal vein invasion （χ²=6.259， P=0.012）， intra-abdominal fat thickness （χ²=7.665， P=0.006）， preoperative biliary drainage （χ²=5.999， P=0.014）， pancreatic cancer （χ²=5.544， P=0.019）， marginal pancreatic thickness （t=2.055， P=0.032）， pancreatic CT value （t=-3.224， P=0.002）， and preoperative blood amylase level （Z=-2.099， P=0.036） were closely associated with POPF， and the multivariate logistic regression analysis showed that main pancreatic duct index （odds ratio ［OR］=0.000， 95% confidence interval ［CI］： 0.000‍ ‍—‍ ‍0.011， P<0.05）， pancreatic cancer （OR=4.843， 95%CI： 1.285‍ ‍—‍ ‍18.254， P<0.05）， and pancreatic CT value （OR=0.869， 95%CI： 0.806‍ ‍—‍ ‍0.937， P<0.05） were independent risk factors； based on the 2016 edition， the univariate analysis showed the diameter of the main pancreatic duct （χ²=5.391， P=0.020）， main pancreatic duct index （χ²=11.394， P=0.001）， intra-abdominal fat thickness （χ²=8.899， P=0.003）， marginal pancreatic thickness （t=2.665， P=0.009）， pancreatic CT value （t=-2.835， P=0.004） were closely associated with POPF， and the multivariate logistic regression analysis showed that main pancreatic duct index （OR=0.001， 95%CI： 0.000‍ ‍—‍ ‍0.050， P<0.05） and pancreatic CT value （OR=0.943， 95%CI： 0.894‍ ‍—‍ ‍0.994， P<0.05） were independent risk factors. A risk prediction model was established for POPF after PD， and the ROC curve analysis showed that this model had an area under the ROC curve of 0.788 （95%CI： 0.707‍ ‍—‍ ‍0.870） in the modeling group and 0.804 （95%CI： 0.675‍ ‍—‍ ‍0.932） in the validation group. ConclusionMain pancreatic duct index and pancreatic CT value are closely associated with POPF after PD， and the risk prediction model for pancreatic fistula based on the 2016 edition has a good prediction accuracy.

OBJECTIVE： To provide reference for the evaluation of the correlation between drugs and adverse drug reaction （ADR） and the implementation of medication therapy management （MTM）. METHODS： Clinical information of a elderly patient with chronic disease （hypertension and coronary heart disease） whose suffered from leukocyte and platelet counts reduction and abnormal liver biochemical examination after taking candesartan were analyzed retrospectively in outpatient department of Tianjin Third Central Hospital. MTM pharmacists analyzed the correlation of candesartan with ADR using Naranjo evaluation scale method. The reasons for abnormal liver biochemical examination were analyzed by Naranjo evaluation scale method combined with Roussel Uclaf causality analysis method （called RUCAM method for short）. The medication reconciliation was conducted according to the results， and pharmacists cooperated with doctors to set individualized medication regimen and follow-up. RESULTS： By Naranjo evaluation scale method， analysis results showed that candesartan was “probably related” to ADR. By RUCAM method， analysis results showed that candesartan was “probably related” to liver biochemical abnormalities. MTM pharmacists suggested that candesartan should be stopped in time and the patient’s medication should be adjusted. The physician and the patient adopted the pharmacist’s advice. After 38 days of drug withdrawal， the patient’s ADR symptoms disappeared， and leukocyte count， platelet count and liver biochemical examination were normal. After adjustment of medication， the patient was followed up for 6 months with normal blood pressure. CONCLUSIONS： Naranjo evaluation scale method and RUCAM are simple and feasible in evaluating the correlation of drugs with ADR and hepatotoxicity. The two methods are consistent in evaluating the correlation between drugs and hepatotoxicity. Naranjo scale method and RUCAM method can be combined to analyze the correlation between drugs and ADR with abnormal liver biochemical examination.

Objective To systematically evaluate the safety and feasibility of enhanced recovery after surgery (ERAS) in perioperative management of pancreatectomy.Methods Literatures were researched using CNKI,Wanfang database,VIP database,PubMed,Cochrane Library,Embase from January 1990 to March 2018 with the key words including "快速康复外科,加速康复外科,胰腺切除术,胰十二指肠切除术,惠普而术,ERAS,enhanced recovery,fast track,pancreatic surgery,pancreatectomy,Whipple,pancreatoduodenectomy,pancreatoduodenal resection".The cohort study about ERAS in elective pancreatic surgery or pancreaticoduodenectomy were received and enrolled.The patients using ERAS in perioperative management and using traditional perioperative management were respectively allocated into the ERAS group and control group.Two reviewers independently screened literatures,extracted data and assessed the risk of bias.Count data were described as odds ratio (OR) and 95％ confidence interval (CI).Weighted Mean Difference (WMD) was used as a consolidated statistics for measurement data that were measured using the same tool,and standardized mean difference (SMD) was used as a consolidated statistics for measurement data that were measured using the different tools.The heterogeneity of the studied was analyzed using the I2 test.Results Nineteen retrospective cohort studies were enrolled in the Meta analysis,and total sample size was 3 699 patients,including 1 823 in the ERAS group and 1 876 in the control group.The results of Meta analysis showed that there were statistically significant differences in the time of postoperative nasogastric tube removal,time for postoperative solid diet intake,time of postoperative defecation recovery,incidence of postoperative overall complications,incidence of postoperative delayed gastric emptying,incidence of postoperative intra-abdominal infection,duration of postoperative hospital stay and hospital expenses between ERAS group and control group (WMD=-1.70,-3.61,-0.86,OR =0.65,0.60,0.70,WMD=-4.64,SMD=-0.48,95％CI:-2.97--0.42,-4.70--2.53,-1.01--0.71,0.52-0.81,0.45-0.80,0.54-0.91,-5.91--3.38,-0.77--0.18,P ＜ 0.05).There was no statistically significant difference in the operation time,volume of intraoperative blood loss,incidence of postoperative pancreatic fistula,incidence of postoperative wound infection,readmission rate,reoperation rate and mortality between ERAS group and control group (WMD=-9.73,-14.39,OR=0.85,0.72,1.05,0.81,0.74,95％CI:-34.24-14.78,-116.96-88.17,0.72-1.01,0.46-1.14,0.83-1.32,0.58-1.13,0.53-1.02,P＞0.05).The results of subgroup analysis showed that heterogeneity of data was from eastern and western countries.Conclusion ERAS in the perioperative management of pancreatectomy is safe and feasible,it can also promote postoperative recovery of patients and reduce incidence of complications and financial burden.
