Objective To explore the efficacy of a new anti-heart failure drug,Entresto,in the prevention of cardiotoxicity caused by doxorubicin(DOX).Methods Male adult ICR mice were randomly divided into three groups(n = 8):control group,DOX group and DOX plus Entresto group.Cardiac function of mice was measured by echocardiography.H9c2 cells were pretreated with Entresto(0-48 μmol/L)for 24 hours in the presence or absence of DOX(1 mmol/L),and then cell viability,oxidative stress,apoptosis and mitochondrial function were evaluated.Results As compared with the control group,leakage of CK,CK-MB and LDH increased significantly in the DOX group(P<0.01),and left ventricular systolic dysfunction occurred.Entresto administration reversed these changes in the DOX group.The level of ROS and the number of apoptotic cells in cardiomyocytes in the DOX plus Entresto group were lower than those in the DOX group(P<0.05).As compared with the DOX group,the level of ROS and the number of apoptotic cells in H9c2 cells decreased significantly in the Entresto plus DOX group(P<0.05),and mitochondrial membrane potential increased significantly(P<0.05).Entresto reversed the inhibitory effect of DOX on SIRT1/PGC-1α/MFN2 signaling pathway.Conclusions Entresto improves DOX-induced cardiotoxicity by inhibiting ROS-mediated oxidative stress and apoptosis,and its mechanism may be related to SIRT1/PGC-1α/MFN2 signal transduction pathway.

Benign anastomotic stenosis remains a common complication after bilojejunal anastomosis. Its pathogenesis includes the histology of bile duct, bile erosion, and inappropriate choice of surgical anastomosis or suture materials. Biliojejunal anastomotic stenosis can be determined preoperatively by MRCP, CT, and three-dimensional image reconstruction. Surgery remains treatment of choice for most cases, including surgical reconstruction and minimally invasive treatment, while the incidence of restenosis, residual stone, and reoperation is still high. Surgeons are still in search of optimal treatment modality to avoid anastomotic stenosis. In this article, we review the literature and summarize the latest clinical progress in the diagnosis and treatment of biliojejunal anastomotic stenosis combined with hepatic ductal stones.

ObjectiveTo observe the effects of Internet plus continuous rehabilitation nursing on older patients after lumbar fusion. MethodsFrom January, 2018 to August, 2021, 157 older patients after transforaminal lumbar interbody fusion (TLIF) in Department of Orthopedics, Chongqing General Hospital were retrospectively studied. A total of 66 patients accepting routine continuous rehabilitation nursing care were as control group, and 91 patients accepting internet plus continuous rehabilitation nursing care were as intervention group. They were assessed with Visual Analog Scale for pain (VAS), Oswestry Disability Index (ODI), Huaxi Emotional-distress Index (HEI) and Adult Health Self-management Skill Rating Scale (AHSMSRS) before, and one and three months after intervention. The compliance and nursing satisfaction were investigated with self-made questionnaire three months after intervention, and the postoperative complications were recorded. ResultsA total of 148 patients finished follow-up of three months, including 61 patients for the control group and 87 patients for the intervention group. The VAS, ODI, HEI and AHSMSRS scores improved in both groups one and three months after intervention (F > 85.4, P < 0.001), and improved more in the intervention group than in the control group (|t| > 3.645, P < 0.001). Both the compliance and nursing satisfaction were better in the intervention group than in the control group (χ² > 5.478, P < 0.05), and no postoperative complication was observed in both groups. ConclusionInternet plus continuous rehabilitation nursing can promote the recovery of function, pain and psychological emotion, ability of self-management, compliance, and nursing satisfaction.

Objective:To study the correlation between biliary angle and hepatolithiasis in liver segment Ⅵ.Methods:A retrospective analysis of the clinical data of 46 patients with liver segment Ⅵ bile duct stones treated at the First Affiliated Hospital of Guangzhou Medical University from January 2017 to January 2021 was carried out. There were 18 males and 28 females, with the age of (55.7±10.5) years. During the study period, 50 patients with cholecystitis were enrolled to form the control group, which consisted of 19 males and 31 females, with the age of (57.4±14.4) years. The angles of the right hepatic duct and the bile duct in segment Ⅵ were measured by the 3D hepatic visualization model. Univariate and multivariate logistic regressions were used to analyze factors correlated with formation of segment Ⅵ bile duct stones.Results:The angles of the segment Ⅵ bile duct (124.5±23.1)° and the right hepatic duct (83.5±14.4)° in the study group were significantly larger than the control group(111.8±27.7)°, (76.9±14.8)°. The difference was significant ( t=2.44, 2.10, P=0.017, 0.039). Analysis showed that the angles of segment Ⅵ bile duct ( OR=1.024, 95% CI: 1.006-1.042, P=0.010) and right hepatic duct ( OR=1.035, 95% CI: 1.005-1.065, P=0.020) correlated with bile duct stones in segment Ⅵ, with greater the angles, greater were the rates of bile duct stones in segment Ⅵ. Receiver operating characteristic curve showed that stones were more commonly formed when the angle of bile duct in segment Ⅵ was over 102.295°. The sensitivity, specificity and area under the curve were 91.3%, 34.0% and 0.631 respectively. Conclusion:The angles of segment Ⅵ bile duct and right hepatic duct were risk factors associated with segment VI bile duct calculi.

Different centers collected and summarized their data in 2017 and sent back the questionnaires for summary. RESULTS: A total of 8 766 AA patients were enrolled from 43 medical centers, including 4 711 males (53.7%) with median age of 39 years and 958 (10.9%) patients over 65 years old. Of 8 776 patients, 5 677 cases (64.6%) received one or more imaging examinations, and the other 3 099 (35.4%) did not receive any imaging examination. A total of 1 858 (21.2%) cases received medical treatment, mainly a combination of nitroimidazoles (1 107 cases, 59.8%) doublet regimen, followed by a single-agent regimen of non-nitroimidazoles (451 cases, 24.4%), a nitroimidazole-free doublet regimen (134 cases, 7.2%), a triple regimen of combined nitroimidazoles (116 cases, 6.3%), nitroimidazole alone (39 cases, 2.1%) and nitroimidazole-free triple regimen (3 cases, 0.2%). Of the 6 908 patients (78.8%) who underwent surgery, 4 319 (62.5%) underwent laparoscopic appendectomy and 2589 (37.5%) underwent open surgery. Ratio of laparotomy was higher in those patients under 16 years old (392 cases) or over 65 years old (258 cases) [15.1%(392/2 589) and 10.0%(258/2 589), respectively, compared with 8.5%(367/4 316) and 8.0%(347/4 316) in the same age group for laparoscopic surgery, χ²=91.415, P<0.001; χ²=15.915,P<0.001]. Patients with complicated appendicitis had higher ratio of undergoing open surgery as compared to those undergoing laparoscopic surgery [26.7%(692/2 589) vs. 15.6%(672/4 316), χ²=125.726, P<0.001].The cure rates of laparoscopic and open surgery were 100.0% and 99.8%(2 585/2 589) respectively without significant difference (P=0.206). Postoperative complication rates were 4.5%(121/2 589) and 4.7%(196/4 316) respectively, and the difference was not statistically significant (χ²=0.065, P=0.799). The incidence of surgical site infection was lower (0.6% vs. 1.7%, χ²=17.315, P<0.001), and hospital stay was shorter [6(4-7) days vs. 6(5-8) days, U=4 384 348.0, P<0.001] in the laparoscopic surgery group, while hospitalization cost was higher (median 12 527 yuan vs. 9 342 yuan, U=2 586 809.0, P<0.001). CONCLUSIONS The diagnosis of acute appendicitis is still clinically based, supplemented by imaging examination. Appendectomy is still the most effective treatment at present. Laparoscopic appendectomy has become the main treatment strategy, but anti-infective drugs are also very effective.
