Objective:To investigate the impact of postoperative complications on adverse outcomes following curative-intent resection for gallbladder cancer (GBC).Methods:The multi-center real-world study was conducted. The clinicopathological data of 629 patients with GBC, who were admitted to 14 medical centers including The First Affiliated Hospital of Army Medical University from the national multicenter database of Biliary Surgery Group of Elite Group of Chinese Journal of Digestive Surgery, from April 2020 to April 2024 were collected. There were 225 males and 404 females, aged (64±10)years. Patients underwent open curative-intent resection for GBC. Observation indicators: (1)surgery, postoperative complica-tions and adverse outcomes; (2) analysis of risk factors affecting postoperative adverse outcomes in patients and population attributable fraction (PAF). Missing data in predictor variables were addressed using multiple imputation with chained equations, while cases with missing outcome variables were addressed using the "multiple imputation then deletion (MID)" strategy. The severity of multicollinearity among independent variables was assessed using the variance inflation factor (VIF) test. Multivariable possion regression models with log link and robust error variance were construc-ted incorporating restricted cubic splines (3 knots) to address nonlinear relationships in continuous variables, calculating adjusted relative risk ( RR) with corresponding 95% confidence interval ( CI). Adjusted PAF was calculated for each imputed dataset using the AF package of R software, with subsequent pooling performed according to Rubin's rules. Results:(1) Surgery, postoperative complications and adverse outcomes. All 629 patients underwent curative-intent resection for GBC, of which 143 cases had postoperative complications, including 68 cases of intra-abdominal ascites, 39 cases of pulmonary infection, 21 cases of bile leakage, 12 cases of intra-abdominal hemorrhage, 11 cases of liver failure, 10 cases of pan-creatic fistula, 10 cases of wound infection, 10 cases of gastroparesis, 7 cases of cholangitis, 7 cases of sepsis. The same patient could have more than one kind of complication. Of 629 patients, there were 19 cases of postoperative 90-day death and 11 cases of missing data, 42 cases with post-operative 90-day reoperation and 7 cases with missing data, 44 cases with postoperative 90-day readmission and 3 cases with missing data, 155 cases with prolonged postoperative hospital stay and 3 cases with missing data. (2) Analysis of risk factors affecting the postoperative adverse outcomes in patients and PAF. Results of multivariate analysis showed that pulmonary infection and liver failure were independent risk factors for postoperative 90-day mortality ( RR=3.74, 12.15, 95% CI as 1.18-11.83, 1.98-74.48, P<0.05). Pulmonary infection demons-trated the highest PAF as 4.61% (95% CI as 3.94%-5.28%, P<0.05). Intra-abdominal ascites, pulmonary infection, bile leakage, and intra-abdominal hemorrhage were independent risk factors for post-operative 90-day reoperation ( RR=4.80, 3.62, 3.46, 4.99, 95% CI as 2.49-9.26, 1.42-9.21, 1.34-8.92, 1.55-16.06, P<0.05). Intra-abdominal ascites demonstrated the highest PAF as 8.65% (95% CI as 8.22%-9.08%, P<0.05). Intra-abdominal ascites, bile leakage, and liver failure were independent risk factors for postoperative 90-day readmission ( RR=6.20, 3.33, 14.33, 95% CI as 3.21-11.95, 1.33-8.35, 3.72-55.28, P<0.05). Intra-abdominal ascites demonstrated the highest PAF as 9.11% (95% CI as 8.85%-9.37%, P<0.05). Intra-abdominal ascites, pulmonary infection, bile leakage, liver failure, and wound infection were independent risk factors for prolonged postoperative hospital stay ( RR=2.29, 2.21, 2.26, 2.14, 3.35, 95% CI as 1.63-3.23, 1.41-3.46, 1.32-3.86, 1.11-4.13, 1.70-6.60, P<0.05). Intra-abdominal ascites demonstrated the highest PAF as 6.03% (95% CI as 5.71%-6.35%, P<0.05). Conclusion:Pulmonary infection is the most significant risk factor for postoperative 90-day mortality after curative-intent resection for GBC, while intra-abdominal ascites is the most significant risk factor for postoperative 90-day reoperation, postoperative 90-day readmission, and prolonged postoperative hospital stay.

Objective To investigate the risk factors of secondary traumatic coagulopathy in patients with traffic trauma.Methods A total of 122 patients with traffic trauma in Department of Emergency Surgery,the First Affiliated Hospital of Anhui Medical University(Dongcheng Hospital)from April 2022 to March 2023 were retrospectively collected.Patients were divided into the occurrence group(n=30)and the non-occurrence group(n=92).Body temperature,acidosis,hematoma enlargement after head CT examination,Glasgow coma score(GCS),trauma severity score(ISS),platelet count(PLT)and hemoglobin(Hb)at admission were collected and compared between the two groups.Multivariate Logistic regression was used to analyze risk factors of secondary traumatic coagulopathy in traffic trauma patients,and receiver operating characteristic(ROC)curve was used to analyze the predictive value of related factors for secondary traumatic coagulopathy.Results The body temperature,GCS,PLT and Hb in the occurrence group were lower than those in the non-occurrence group,while the ISS,incidence of acidosis and the incidence of increased hematoma after CT examination were higher than those in the non-occurrence group(all P<0.05).Multivariate Logistic regression analysis showed that low GCS,low Hb level,high ISS,acidosis and increased hematoma after head CT examination were risk factors at admission(P<0.05).The area under ROC curve(AUC)of the five factors combined for secondary traumatic coagulopathy in traffic trauma patients was 0.963,sensitivity was 83.3%and specificity was 96.7%.Conclusion Decreased GCS and Hb on admission,high ISS,acidosis and increased hematoma during head CT review are risk factors for secondary traumatic cotting disorder in traffic trauma patients,and the combination of these factors has high predictive value.

Alveolar echinococcosis, caused by Echinococcus multilocularis infection, is a highly deadly zoonotic parasitic disease. As a benzimidazole compound, albendazole has a strong and broad-spectrum anti-parasitic action. For alveolar echinococcosis patients that are unwilling to receive surgical treatment, lose the timing for surgery, or are intolerant to surgery due to poor physical status, administration of albendazole may delay disease progression. Recently, a large number of advances have been achieved in experimental studies on alveolar echinococcosis. In order to increase the understanding of the therapeutic efficacy of albendazole for alveolar echinococcosis, this review summarizes the advances in albendazole treatment for alveolar echinococcosis, so as to provide insights into the clinical treatment of alveolar echinococcosis with albendazole.

Acyl-CoA synthetase long chain family member 5 (ACSL5), is a member of the acyl-CoA synthetases (ACSs) family that activates long chain fatty acids by catalyzing the synthesis of fatty acyl-CoAs. The dysregulation of ACSL5 has been reported in some cancers, such as glioma and colon cancers. However, little is known about the role of ACSL5 in acute myeloid leukemia (AML). We found that the expression of ACSL5 was higher in bone marrow cells from AML patients compared with that from healthy donors. ACSL5 level could serve as an independent prognostic predictor of the overall survival of AML patients. In AML cells, the ACSL5 knockdown inhibited cell growth both in vitro and in vivo. Mechanistically, the knockdown of ACSL5 suppressed the activation of the Wnt/β-catenin pathway by suppressing the palmitoylation modification of Wnt3a. Additionally, triacsin c, a pan-ACS family inhibitor, inhibited cell growth and robustly induced cell apoptosis when combined with ABT-199, the FDA approved BCL-2 inhibitor for AML therapy. Our results indicate that ACSL5 is a potential prognosis marker for AML and a promising pharmacological target for the treatment of molecularly stratified AML.

Objective To investigate the effect of exosomes derived from Echinococcus multilocularis on macrophage polarization after treatment for different durations and concentrations. Methods A total of 60 BALB/c mice were used for modeling, among which 4 mice were selected to observe the growth of abdominal lesions on 7.0T MRI. The mice for modeling were dissected, and the protoscoleces was taken from the abdominal lesion and cultured in vitro ; ultracentrifugation was used to extract the exosomes from the supernatant, and transmission electron microscopy and Western blotting were used for the characterization of exosomes. The macrophages without exosome treatment were established as control group, and the macrophages co-cultured with different concentrations of exosomes derived from Echinococcus multilocularis were established as experimental group (10 μg/mL group and 50 μg/mL group) and were cultured for 48 and 72 hours. The morphological changes of macrophages were observed under a microscope, and flow cytometry and ELISA were used to observe polarization state. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference t -test was used for further comparison between two groups. Results The results of 7.0T MRI showed the formation of diffuse lesions with different sizes in the abdominal cavity of mice, and the exosomes derived from Echinococcus multilocularis were approximately 100 nm in diameter and were cup-shaped or saucer-shaped, with the positive expression of the surface markers CD9, TSG101, and CD63. After co-culture, most of the cells in the experimental group were elongated with an irregular and polygonal shape. Flow cytometry showed that after 48 hours of co-culture, the positive rates of CD16/32, CD206, and CD369 in the control group were 99.53%±0.06%, 90.27%±0.21%, and 2.40%±0.20%, respectively; compared with the control group, except that the 10 μg/mL exosome group had a significant reduction in the positive rate of CD369 (0.80%±0.00%) ( P < 0.05), all the other groups had a significant increase in the positive rates of CD16/32, CD206, and CD369 (all P < 0.000 1); after 72 hours of co-culture, the positive rates of CD16/32, CD206, and CD369 in the control group were 99.67%±0.06%, 85.47%±0.55%, and 6.60%±0.20%, respectively, and compared with the control group, the experimental group had significant increases in the positive rates of CD16/32, CD206, and CD369 (all P < 0.05). ELISA showed that after 48 hours of co-culture, the levels of IL-6 and TNFα in the control group were 58.53±15.52 pg/mL and 320.70±5.30 pg/mL, respectively, and when the exosome concentration was 50 μg/mL, the level of IL-6 in the experimental group was 98.81±15.55 pg/mL, which was higher than that in the control group ( P < 0.05); after 72 hours of co-culture, the levels of IL-6 and TNFα in the control group were 76.22±9.68 pg/mL and 323.90±87.37 pg/mL, respectively, and when the exosome concentration was 10 μg/mL, the level of TNFα was 164.20±14.17 pg/mL, which was significantly lower than that in the control group ( P < 0.05); when the exosome concentration was 50 μg/mL, the level of IL-6 was 99.52±8.35 pg/mL, which was significantly higher than that in the control group ( P < 0.05). Conclusion Exosomes derived from Echinococcus multilocularis can regulate macrophage polarization and induce M2-like polarization of macrophages after co-culture at a concentration of 10 μg /mL for 72 hours, and further studies are needed to clarify the specific method.

The quality control of lung transplantation involves many aspects, such as team building, selection of recipients, preoperative diagnosis and evaluation of recipients, maintenance of brain-dead donors, evaluation and acquisition of donors, surgical operation, postoperative management and postoperative follow-up. Precision management is the core concept of operation quality control. Only by normalizing the operation quality control of lung transplantation to provide basic guarantee for multi-team cooperation and development of lung transplantation management in the future, building a complete lung transplantation database to excavate data resources and improve the quality of transplanta-tion, and comprehensively building a Chinese lung transplantation quality control system with multi-team participation and cooperation, can we improve the overall level of surgical diagnosis and treatment of lung transplantation in China.

The precise resection and suture of bronchia, vascular and pulmonary tissue are the key techniques in thoracic surgery. Mechanical suture technique has gradually become a routine operation in thoracic surgery. However, at present, there is still a lack of consensus and guidelines on the application of this technique in thoracic surgery, neither strong evidence-based medical support. In this study, we discuss the application standard of mechanical suture technique in thoracoscopic surgery, irregular treatment techniques, intraoperative complications, and management principles to promote the standardized application of mechanical suture technique. We also explain the shortcomings of the technique in order to promote the further improvement and perfection.

Background and aim:Real-world data on the effectiveness and safety of treatment with the direct-acting antiviral agent-based regimen are limited on the Chinese mainland.The aim of this study was to conduct a multicenter,prospective,real-world study of ombitasvir/paritaprevir/ritonavir(OBT/PTV/r)combined with dasabuvir(DSV)in hepatitis C virus(HCV)genotype 1b-infected non-cirrhotic or compensated cirrhotic Chinese adult patients. Materials and methods:Genotype 1b-infected patients were enrolled at eight sites in China.Patients received 25/150/100 mg of OBT/PTV/r once daily combined with 250 mg of DSV twice daily for 8 weeks or 12 weeks.Sustained virological response at 12 weeks post-treatment(SVR12)and the incidence of adverse events were assessed.We have also evaluated the effect of intensive questioning of patients who were overdue for SVR12 testing.Intention-to-treat(1TT)and modified 1TT(mITT)populations were used in the analysis. Results:One hundred forty patients were included,among whom 90.0％(126/140)were newly diag-nosed,9.3％(13/140)had compensated cirrhosis,92.9％(130/140)received 12 weeks of treatment,and 7.1％(10/140)received 8 weeks of treatment.In the mITT population,the virological response rate at week 4 was 96.4％(108/112),and at the end of treatment was 100％(102/102).Among these patients,139 patients completed 12 weeks of treatment,and 73 patients were followed-up.All followed-up patients achieved SVR12.There was no adverse event-related discontinuation.Serious adverse events during treatment were reported in two(1.4％)patients,and none were considered to be drug-related.Sixty-six(47.1％)patients did not return to receive the HCV RNA test at 12 weeks post-treatment. Conclusions:The rate of SVR12 was consistent with Phase Ⅲ clinical studies.OBT/PTV/r combined with DSV showed effectiveness in Chinese adult patients,and both tolerability and safety profile were favorable.However,patient compliance should be further improved in the real world.
