0.05), which shows that two kinds of patches from American Bard Corporation and the American Auto Suture Company have the similar effectiveness, but patch material has no direct relationship with complication occurrence.

Objective:To assess the safety and efficacy of induction chemotherapy with cisplatin and docetaxel followed by radia-tion concurrent with weekly cisplatin for unresectable, locally advanced esophageal cancer. Methods: Thirty-three patients with T3N0M0 to T4N2M0 thoracic esophageal squamous cell carcinoma without celiac lymph node metastasis were included in the study. They were treated with cisplatin (75 mg/m2 d1, d22) and docetaxel (75 mg/m2 d1, d22) neoadjuvant chemotherapy followed by three-dimensional conformal radiotherapy (60Gy/30F/6w) concurrent with cisplatin (30 mg/m2 d1, 8, 15, 22, 29, 36 from the beginning of radiation). Results:Grade 4 hematological toxicities were observed in 13.33%(4/33) of the patients after the neoadjuvant chemother-apy. No grade 3 or above hepatic or renal toxicities were found. During concurrent chemoradiation, the highest grade 3 hematological toxicities were observed in the erythrocyte, granulocyte, and macrophage at 21.21%(7/33), 15.15%(5/33), and 3.01%(1/33), respec-tively. No grade 2 or above hepatic or renal toxicities were observed. Grade 3 radiation esophagitis was observed in 9.1%(3/33) of the patients, whereas grade 3 and above radiation esophagitis or grade 1 and above acute radiation pneumonitis did not occur. The evalua-tion results after treatment completion were 84.85%(28/33), 12.12%(4/33), and 3.03%(1/33) for CR+PR, SD, and PD , respectively. Two months after treatment completion, the results changed to 75.76%(25/33), 9.10%(3/33), and 15.15%(5/33), respectively. Overall, 15 patients died. The one-year survival rate was 66.4%. Local failure was approximately 46.67%(7/15), whereas the local+distant fail-ure was approximately 26.67%(4/15). Therefore, local failure is the main pattern of failure in esophageal cancer. Conclusion:The re-sults indicate that neoadjuvant chemotherapy with cisplatin and docetaxel followed by radiotherapy concurrent with weekly cisplatin for locally advanced esophageal cancer is safe. Local failure remains the main pattern of failure in esophageal cancer.

We aimed to explore what kind of endocrine treatments are optimal for hormone receptorpositive and human epidermal growth factor receptor 2-negative locally advanced or metastatic breast cancer in some specific clinical situations. We searched randomized controlled trials in Embase, Medline, the Cochrane library, and PubMed from inception to April 1, 2020 and performed a network meta-analysis based on a Bayesian fixed-effects model. Progression-free survival (PFS) with hazard ratios and corresponding 95% confidence interval was defined as the primary endpoint, while overall survival (OS), objective response rate (ORR), clinical benefit rate and serious adverse events were used as secondary endpoints. A total of 35 studies involving 12,285 patients and 24 treatment options were included. In general, most co-treatment options prolonged PFS compared to single-agent therapy, of which aromatase inhibitor (AI) plus everolimus and fulvestrant plus palbociclib were probably the most effective agents, and the latter had the best safety record. However, despite the superior efficacy of fulvestrant plus capecitabine for PFS and OS, palpable toxic effects have been demonstrated for this treatment, so its application must be scrupulously considered. The results of subgroup analysis indicated that fulvestrant combined with palbociclib improved prognosis for phosphatidylinositol 3-kinase (PI3K)-mutated patients, PI3K-unmutated patients, patients with endocrine therapy resistance, and visceral metastatic patients, while no obvious improvement was detected in OS. Moreover, the efficacy of fulvestrant plus cyclin-dependent kinase 4/6 (CDK4/6) inhibitors was slightly better than that of AI plus CDK4/6 inhibitors, while AI plus everolimus was more efficacious than fulvestrant combined with everolimus in terms of PFS, OS, and ORR. In conclusion, our results provide moderate evidence that fulvestrant plus palbociclib and AI plus everolimus were the most effective treatments, while the efficacy and safety of fulvestrant plus palbociclib was obviously superior in some specific clinical situations.

Objective To study protective and therapeutic measures to improve perioperative safety in extremely elderly patients with biliary diseases.Methods A retrospective case-control study was conducted.The clinical data of elderly patients with biliary diseases treated at the Department of General Surgery,Beijing Electric Power Hospital,from July 2013 to December 2018,were collected.According to age,the patients were divided into the high age (HA) group (≥80.0 years) and the middle-low age (MLA) group (60.0～79.0 years).The related indexes of perioperative safety such as preoperative coexisting diseases,functions of liver,kidney,heart and lung,surgical procedures,intraoperative blood loss,operation time,postoperative hospital stay and postoperative hospital stay were analyzed and compared between the two groups.Results Of the 372 included patients,there were 168 males and 204 females,aged 60.0 to 96.0 (72.0 ± 8.6) years.There were 69 elderly patients (37 males and 32 females) aged 80.0 to 96.0 (84.4 ±3.8) years in the HA group.There were 303 patients in the middle and lower age group (131 men and 172 women),aged 60.0 to 79.0(68.4 ±5.8) years (MLA group).(1) Preoperative coexisting diseases were significantly increased in the HA compared with the MLA group (all P ＜ 0.05),including the proportion of coexisting coronary heart disease [34.8％ (24/69) vs.18.5％ (56/303)],hypertension [68.1％ (47/69)vs.46.9％ (142/303)],chronic bronchitis with emphysema [17.4％ (12/69) vs.3.6％ (11/303)],hypoproteinemia [39.1％ (27/69) vs.26.7％ (81/303)],and anemia [42.0％ (29/69) vs.11.9％ (36/303)].(2) Laboratory examinations:the functions of liver,kidney,heart,lung and blood coagulation were significantly worse in the HA compared with the MLA group (P ＜ 0.05).(3) Surgical procedures:the proportion of open cholecystectomy with transcystic common bile duct exploration (OC + OTCBDE) was higher [17.4％ (12/69) vs.6.9％ (21/303)],while laparoscopic cholecystectomy (LC) was lower [43.5％ (30/69) vs.62.7％ (190/303)],in the HA compared with the MLA group (P ＜0.05,totally).(4) Operative effects:the intraoperative blood loss [30.0 (20.0,75.0) ml vs.20.0 (10.0,30.0) ml],operation time [90.0(72.5,137.5) min vs.77.0(55.0,115.0) min],postoperative hospital stay [10.0(6.0,18.0) d vs.7.0(4.0,11.0) d],and length of hospitalization [17.0(11.5,23.0) d vs.13.0(9.0,19.0) d] were significantly increased or prolonged in the HA compared with the MLA group (all P ＜0.05).(5) Postoperative complications:the incidence of postoperative complications was significantly higher [30.4％ (21/69) vs.12.2％ (37/303)] in the HA compared with the MLA group (P ＜ 0.05).(6) Therapeutic outcomes:there was a cure rate of 95.7％ (66/69) in the HA group,and 97.7％ (296/303)in the MLA group.No significant difference in the therapeutic effects was found between the two groups (P ＞ 0.05).Conclusions Operation in extremely elderly patients with biliary diseases is safe and feasible.The key is to take measures such as actively treating preoperative coexisting diseases,strictly mastering operative indications,reasonably selecting surgical procedures,accurately carrying out precise operation,strictly monitoring and dealing with intraoperative emergency,timely preventing and treating postoperative complications,and especially focusing on maintaining cardiopulmonary function during the perioperative period.

Objective:The purpose of this study was to explore the critical values of monitored indexes of perioperative major adverse cardiac events(MACE), so as to take effective prevention and treatment measures in time to maintain the stability of perioperative cardiac function to further improve the perioperative safety of elderly patients with biliary diseases.Methods:The clinical data of 246 elderly patients with biliary diseases in our hospital from May 2016 to February 2022 were collected.According to whether MACE occurred during the perioperative period, they were divided into the MACE group and the non-MACE group.The differences of clinical data, the monitoring indexes of postoperative cardiac function, and the coagulation function between the two groups were compared and analyzed.Logistic regression was used to analyze the independent risk factors of perioperative MACE, the cut-off value of the receiver operating characteristic(ROC)curve was calculated, and the Logistic multivariate prediction model was established.Results:In the MACE compared with the non-MACE group, age, postoperative complications and mortality, postoperative hospital stay, and the levels of postoperative high sensitivity troponin-I(Hs-TnI), creatine kinase isoenzyme(CK-MB), myoglobin(MYO), B-type natriuretic peptide(BNP), and D-dimer(D-D)were significantly increased(all P<0.05). Multivariate Logistic regression showed that postoperative BNP and D-D were two independent risk factors for perioperative MACE, and their cut-off values in the ROC curve were 382.65 pg/mL and 0.975mg/L respectively.The Logistic multivariate prediction model established by the Logistic regression equation was P= ex/(1+ ex), X=-5.710+ 0.003X 1+ 0.811X 2, where X 1 was the postoperative BNP level and X 2 was the postoperative D-D level.The accuracy, specificity and sensitivity of this prediction model for predicting perioperative MACE were 96.3%(237/246), 100.0%(235/235), and 18.2%(2/11). Conclusions:The Logistic multivariate prediction model established in this study can effectively predict the occurrence of perioperative MACE in elderly patients.Postoperative BNP and D-D were two independent risk factors for perioperative MACE.The cut-off values of BNP and D-D in the ROC curve could be used as critical values for monitoring perioperative MACE.Therefore, it is of great clinical significance to take effective prevention and treatment measures in time to maintain the stability of perioperative cardiac function, and further improve the perioperative safety of elderly patients with biliary diseases.

Objective To investigate the expression of ubiquitin binding enzyme E2T (UBE2T) in breast cancer (BRCA) and its role and mechanism in the prognosis of BRCA patients. Methods The Tumor Genome Atlas (TCGA) database was used to analyze UBE2T expression in BRCA tissues, and the effects of UBE2T expression on disease-free survival (DFS) and overall survival (OS) were analyzed by Kaplan-Meier (KM) survival curve. In vitro, real-time quantitative PCR and Western blot were used to confirm the knock-down and overexpression efficiency, to analyze its effect on tumor cell biological behavior. The effect of UBE2T on cell epithelial–mesenchymal transition (EMT) was studied by Western blot. A xenograft tumor model was established to verify the effect of UBE2T knockdown on the growth of BRCA cells in vivo. Results The UBE2T expression levels in BRCA and adjacent tissues were statistically different (P<0.001), and the expression was increased in tissues with distant metastasis or late stage (all P<0.05). The DFS and OS were decreased in the UBE2T high-level group (both P<0.05). UBE2T was highly expressed in MCF-7 and MDA-MB-231 cells and lowly expressed in MDA-MB-361 cells (all P<0.01). After UBE2T was silenced by shRNA, the proliferation ability of tumor cells significantly decreased, whereas it increased after UBE2T up-expression (all P<0.05). The apoptotic rates of MCF-7 and MDA-MB-231 cells in the silent groups were significantly higher than those in the shNC groups, while the apoptotic rates of MAD-MB-361 cells in the overexpression group decreased (all P<0.001). The mobility in the knockdown groups were lower than in the shNC groups, while the mobility in the overexpression group significantly increased (both P<0.01). The migration and invasion cells in the shUBE2T groups were lower than those in the shNC groups, and the migration and invasion cells in the UBE2T group were higher than those in the vector group (all P<0.01). Downregulation of UBE2T decreased the expression levels of N-cadherin, Snail, and Vimentin (all P<0.05) and increased that of E-cadherin; however, the result of UBE2T upregulation was opposite (all P<0.01). TIMER results showed that UBE2T was positively correlated with E-cadherin (P<0.001), N-cadherin (P=0.013), and Snail (P<0.001) and negatively correlated with Vimentin (P<0.001). In vivo experiments showed that downregulation of UBE2T slowed down the growth of transplanted tumors. Conclusion UBE2T is highly expressed in BRCA tissues and may affect the prognosis. UBE2T can promote the proliferation of BRCA cells, inhibit apoptosis, and increase the migration and invasion abilities by changing the expression levels of EMT-related proteins.

With the accelerated aging society in China, the incidence of biliary surgical diseases in the elderly has increased significantly. The clinical characteristics of these patients indicate that improving treatment outcomes and realizing healthy aging are worthy of attention. How to effectively improve the treatment effect of geriatric biliary surgical diseases has attracted widespread attention. This paper reviews and comments on the hotspots and difficulties of biliary surgery in older patients from six aspects: (1) higher morbidity associated with an aging society, (2) prevention and control of pre-operative risks, (3) extending the indications of laparoscopic surgery, (4) urgent standardization of minimally invasive surgery, (5) precise technological progress in hepatobiliary surgery, and (6) guarantee of peri-operative safety. It is of great significance to fully understand the focus of controversy, actively make use of its favorable factors, and effectively avoid its unfavorable factors, for further improving the therapeutic effects of geriatric biliary surgical diseases, and thus benefits the vast older patients with biliary surgical diseases. Accordingly, a historical record with the highest age of 93 years for laparoscopic transcystic common bile duct exploration has been created by us recently.
