Objective:To analyze the effects of hemoglobin, albumin, lymphocyte and platelet count (HALP) scores on the survival of gallbladder cancer patients after radical surgery, and to construct a prognostic prediction model and evaluate based on HALP scores.Methods:The clinical data of 95 patients with gallbladder cancer who underwent surgical treatment in Fuzong Clinical Medical College of Fujian Medical University (the 900th Hospital) from January 2010 to December 2022 were retrospectively analyzed, including 40 males and 55 females, with the age of (63.3±12.2) years. All patients were divided into a low HALP group (HALP score ≤35.4, n=45) and a high HALP group (HALP score >35.4, n=50) based on the optimal cut-off value of 35.4 for predicting postoperative survival as determined by the receiver operating characteristic (ROC) curve. Survival curves were plotted by the Kaplan-Meier method, and survival comparisons were performed using the log-rank test. Univariate and multivariate Cox regression were used to analyze the effect of HALP score on survival after radical surgery in patients with gallbladder cancer. Based on the multifactorial results, nomogram was constructed to predict the survival of gallbladder cancer patients after radical surgery, and ROC curves, consistency indexes were evaluated in the model. Results:A total of 95 patients were followed up for 1-150 months, with a median of 13 months. The 1-, 3-, and 5-year postoperative cumulative survival rates of patients in the low HALP group were 56.2%, 31.2%, and 11.1%, respectively, which were lower than those of the high HALP group, which were 82.9%, 59.6%, and 40.7%, and the difference was statistically significant ( χ2=12.50, P<0.001). Based on multifactorial Cox regression analysis, preoperative total bilirubin ≥23 μmol/L, with lymph node metastasis, tumor TNM stage Ⅲ-Ⅳ, and postoperative incision infection were the risk factors for survival after radical surgery in patients with gallbladder cancer, and a HALP score of >35.4 and Child-Pugh A were protective factors (all P<0.05). Based on the results of multivariate Cox regression analysis to construct a nomogram for predicting overall survival after radical surgery in patients with gallbladder cancer, the consistency index between the prediction of the nomogram and the actual situation was 0.801 (95% CI: 0.752-0.850), and the area under the ROC curve for predicting overall survival was 0.812 (95% CI: 0.704-0.902). Conclusion:The preoperative high HALP score (HALP > 35.4) is a protective factor for survival after radical surgery in gallbladder cancer patients, and the nomogram constructed based on the HALP score for survival prediction after radical surgery for gallbladder cancer has high accuracy and can be used for the assessment of postoperative survival.

Objective:To investigate the application value of mesocolon approach in transanal total mesorectal excision (TaTME).Methods:The retrospective cohort study was conducted. The clinicopathological data of 61 patients with middle or low rectal cancer who were admitted to the Nanchong Central Hospital of North Sichuan Medical College from January to December in 2018 were collected. There were 41 males and 20 females, aged from 43 to 81 years, with an average age of 62 years. Of the 61 patients, 30 patients undergoing TaTME with the conventional approach were allocated into traditional approach group, and 31 patients undergoing TaTME with mesocolon approach were allocated into mesocolon approach group. Observation indicators: (1) surgical situations; (2) postoperative recovery; (3) follow-up. Follow-up was conducted by outpatient examination and telephone interview once every 3 months to detect local recurrence and metastasis of tumors in patients up to June 2019. Measurement data with normal distribution were expressed as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were expressed as M (range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups were analyzed using the chi-square test or Fisher exact probability. Comparison of ordinal data between groups was analyzed using the Mann-Whitney U test. Results:(1) Surgical situations: patients in the two groups underwent TaTME successfully, without conversion to laparotomy. The transabdominal operation time, volume of intraoperative blood loss, length of distal margin from surgical specimen, length of proximal margin from surgical specimen, cases with complete mesentery or with nearly complete mesentery ( the integrity of mesentery ), positive rate of circumferential margin, positive rate of distal margin, and the number of lymph node dissected of the traditional approach group were (126±56)minutes, 41.0 mL (range, 17.5-71.4 mL), 1.3 cm (range, 0.8-2.0 cm), (10.0±5.0)cm, 10, 20, 3.3%(1/30), 0, 13.7 (range, 9.0-17.0), respectively, versus (101±30)minutes, 44.0 mL (range, 25.0-67.5 mL), 1.6 cm (range, 1.1-2.2 cm), (12.0±3.0)cm, 23, 8, 6.5%(2/31), 0, 13.0 (range, 10.9-17.3) of the mesocolon approach group. There were significant differences in the transabdominal operation time, length of proximal margin from surgical specimen, and the integrity of mesentery between the two groups ( t=2.133, -2.286, χ2=10.250, P<0.05). There was no significant difference in the volume of intraoperative blood loss, length of distal margin from surgical specimen, or the number of lymph node dissected between the two groups ( Z=-0.662, -1.107, 0.304, P>0.05). There was also no significant difference in the positive rate of circumferential margin or positive rate of distal margin between the two groups ( P>0.05). (2) Postoperative recovery: the time to first anal flatus of the traditional approach group was 51 hours (range, 48-64 hours). There were 3 patients with complications in the traditional approach group. One patient in the traditional approach group had postoperative anastomotic fistula of Clavien-Dindo classification Ⅱ, and was cured after conservative treatment including sufficient drainage, parenteral nutrition and anti-infective treatment. One patient had chylous fistula of Clavien-Dindo classification Ⅱ, and was cured after conservative treatment. One patient had pulmonary infection of Clavien-Dindo classification Ⅳa, and was cured after treatment in ICU. The duration of postoperative hospital stay of the traditional approach group was (11.3±4.5)days. The time to first anal flatus of the mesocolon approach group was 59 hours (range, 49-70 hours). One patient in the mesocolon approach group had paralytic ileus of Clavien-Dindo classification Ⅰ, and was cured after conservative treatment. The duration of postoperative hospital stay of the mesocolon approach group was (9.6±1.8)days. There was no significant difference in the time to first anal flatus or duration of postoperative hospital stay between the two groups ( Z=-0.554, t=1.884, P>0.05). There was no significant difference in the complications between the two groups ( P>0.05). (3) Follow-up: 61 patients were followed up for 6-18 months, with a median time of 12 months. There was no local recurrence or metastasis of tumors in patients during the follow-up. Conclusion:The mesocolon approach is safe and feasible in TaTME, which abides by the principle of radical resection, and can decrease the difficulty of mesocolon excision, shorten the time of transabdominal operation, increase the length of proximal margin from tumor specimen, improve the integrity of mesentery.

Objective:To understand the characteristics and associated factors of newly reported HIV/AIDS cases with non-marital or non-commercial heterosexual transmission, in Guangxi Zhuang Autonomous Region (Guangxi), 2015-2018.Methods:Information of newly reported HIV/AIDS cases aged ≥18 years in Guangxi between 2015 and 2018 was collected from the National Comprehensive HIV/AIDS Information System. Unconditional logistic regression model was used to access those factors that were associated with HIV infections through non-marital or non-commercial heterosexual contact.Results:Between 2015 and 2018, a total number of 35 497 HIV/AIDS cases, aged ≥18 years were newly reported in Guangxi. Among them, 32 648 (92.0 %) were infected heterosexually while 10 500 were infected through non-marital or non-commercial heterosexual behavior. Non-marital or non-commercial heterosexual transmission accounted for 29.6 % (10 500/35 497) of the newly reported HIV/AIDS cases, and 32.2 % (10 500/32 648) of those with heterosexual transmission. Males counted for 53.5 % (5 617/10 500) of non-marital or non-commercial heterosexual transmission and males to females ratio was 1.2∶1 (5 617∶4 883). Those married or had regular sexual partners counted for 55.9 % (5 873/10 500). Commercial heterosexual transmission appeared the main mode of HIV transmission for males (64.4 %,16 516/25 633) while main mode for females was non-marital or non-commercial heterosexual transmission and counted for 49.5 % (4 883/9 864). Results from the multivariate logistic regression analysis showed that adjusted OR of female HIV/AIDS infected HIV via non-marital or non-commercial heterosexual transmission, was 3.98 times (95 %CI: 3.78-4.20) hight than that of males. Among the group aged<50 years and the aged 50-59 years, the adjusted ORs were 1.35 times (95 %CI: 1.27-1.44) and 1.13 times (95 %CI: 1.05-1.21) hight than that of aged ≥60 years. Those who were single/divorced/widowed, the adjusted OR was 1.53 times (95 %CI: 1.45-1.61) hight than that of those married/regular partners. Those with junior high school education, high school education and above the adjusted ORs were 1.22 times (95 %CI: 1.16-1.29) and 1.18 times (95 %CI: 1.10-1.27), compared to those only with education levels of primary school or below. Conclusions:The number of HIV/AIDS cases via non-marital or non-commercial heterosexual transmission accounted for nearly 30.0 % of all the routes of HIV transmission in Guangxi, 2015-2018. Female, aged<60 years old, single/divorced/widowed and having had junior and above high school education etc., appeared as risk factors on non-marital or non-commercial heterosexual transmission, among newly reported HIV/AIDS in Guangxi.

Objective: To understand the characteristics of HIV/AIDS epidemic in Guangxi Zhuang Autonomous Region (Guangxi) with a purpose to accurately provide scientific basis for prevention and control measures, 2010-2017. Methods: Data were retrieved from case reporting cards of Guangxi during 2010 to 2017 through National HIV/AIDS Comprehensive Response Information Management System. Data was analyzed using epidemiological methods such number of cases, proportion and rate. χ² test was used for statistical analysis. Results: The HIV positive rate was 12.53 per ten thousand (85 182/67 959 000) in Guangxi during 2010 to 2017. The number of newly diagnosed HIV/AIDS cases and the number of death yearly respectively increased by 22.34%(2 602/11 648) and 32.83% (952/2 900) in 2011 compared with 2010, and both showed a six-year continuous downward trend (the number of newly diagnosed cases respectively 12 229 cases, 10 877 cases, 9 460 cases, 9 190 cases, 8 848 cases, 8 680 cases, and the number of death respectively 3 888 cases, 3 316 cases, 2 914 cases, 2 717 cases, 2 595 cases, 2 600 cases) from 2012 to 2017. But proportion of late discovery remained above 50.00% (50.53%-57.06%) for eight-years continuously. The ratio of male and female was 2.47 ∶ 1 (60 639/24 543). The ratio of males and females aged 50 and over was 2.71∶1 (28 654/10 557). Proportion of the cases in 25-49 years old group and 50 years old group accounting for 47.40%(40 377/85 182) and 46.03% (39 211/85 182) respectively. The occupation was farmers accounting for 68.40% (58 262/85 182), housekeeping, housework and unemployment accounting for 11.21% (9 546/85 182), student accounting for 0.86% (729/85 182). Heterosexual transmission accounted for 90.60% (77 171/85 182, homosexual transmission accounted for 3.13% (2 669/85 182), injection drug use transmission accounted for 4.60%(3 924/85 182) and mother-to-child transmission accounted for 0.73% (619/85 182). Conclusions The number of newly diagnosed cases and the number of death yearly showed a continuous downtrend for six-years from 2012 to 2017. However, proportion of late discovery remained above 50.00% for eight-years. The major route of infection was heterosexual transmission. With the change of HIV/AIDS newly epidemic mode in Guangxi, there are many new challenges for HIV/AIDS prevention and control work. Strategy of targeted intervention modes should be innovated for a new breakthrough.
