ObjectivesTo compare the clinical efficacy and complications of anatomic locking titanium plate （hereinafter referred to as “titanium plate screw”） and intramedullary nail in the treatment of distal tibial fractures.Methods From September 2019 to September 2021， 32 patients diagnosed with AO-A fracture of distal tibia at Sun Yat-sen Memorial Hospital of Sun Yat-sen University were included in this study. Of these， 15 cases were treated with titanium plate screws and 17 cases were treated with intramedullary nails. General surgical indexes， fracture healing time and postoperative operation were compared between the two groups.ResultsAll patients were followed up for 10 to 20 months， with an average of 12 months. The operative time and intraoperative fluoroscopy times of intramedullary nail group were longer than those of titanium plate screw group， but the preoperative waiting time and hospitalization days was less or were fewer than those of titanium plate screw group， the difference was statistically significant （P < 0.05）. There was no significant difference in fracture healing time between the two groups （P> 0.05）. At 6 weeks after operation， VAS scores in both groups were lower than those before operation， with statistically significant difference （P<0.05）. There was no significant difference in VAS scores between the intramedullary nail group and the titanium plate screw group （P> 0.05）. AOFAS scores 6 months after surgery， ankle joint motion and complication rate 1 year after surgery in intramedullary screw group were better than those in titanium plate screw group， and the differences were statistically significant （P< 0.05）. There was no significant difference in AOFAS scores between the two groups at 1 year after operation （P> 0.05）.ConclusionTitanium plate screw and intramedullary nail are both effective methods for the treatment of distal tibial AO-A fracture， and there is no significant difference in long-term clinical efficacy. Intramedullary nail has fewer soft tissue complications， less impact on ankle motion， faster recovery and higher safety， while titanium plate screw has a higher probability of postoperative soft tissue infection. We suggest that in clinical work， preoperative evaluation of patients should be done well. Under the premise of grasping the indications， intramedullary nail has fewer complications and certain advantages.

Objective:To understand the status of hepatitis B detection, prenatal care and antiviral treatment for hepatitis B positive pregnant women, and to provide scientific basis for the elimination of mother-to-child transmission of hepatitis B.Methods:The information of hepatitis B positive maternal case registration cards in Hunan Province during 2021-2023 was collected from the National Integrated Prevention of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS), syphilis and hepatitis B mother-to-child transmission (IPMTCT) information management system. The status of hepatitis B detection, demographic characteristics of hepatitis B positive pregnant women, delivery methods, antiviral drugs and so on were analyzed retrospectively.Results:The hepatitis B detection rate of pregnant women in Hunan Province from 2021 to 2023 was 99.99%(1 196 261/1 196 370), and the positive rate of hepatitis B decreased year by year (χ 2trend=37.570, P<0.001). The education level of 75 542 hepatitis B positive pregnant women was generally low, and most of them were middle schools (63.4%, 47 893 cases). The proportion of hepatitis B positive pregnant women diagnosed in early pregnancy increased year by year (χ 2trend=414.202, P<0.001). The delivery mode of hepatitis B positive pregnant women were mainly natural childbirth and elective cesarean section. The rate of hepatitis B positive pregnant women with high risk of mother-to-child transmission increased from 47.4%(924/1 949) to 80.9%(2 238/2 768) (χ 2trend=570.003, P<0.001). Conclusions:It is necessary to strengthen the health education of hepatitis B positive pregnant women, optimize the management process of antiviral treatment for hepatitis B positive pregnant women with high risk of mother-to-child transmission, and further improve the rate of antiviral treatment, so as to reduce the risk of mother-to-child transmission of HBV.

The procurement, preservation and transportation of the donor organs directly affect the clinical prognosis of the recipients. The establishment of process optimization and quality control standards of organ procurement, preservation and transportation contributes to improving the quality and utilization rate of donor organs and reducing the medical risk. According to Guide to the Quality and Safety of Organs for Transplantation (6th edition) proposed by European Union, the 11th chapter of organ procurement, preservation and transportation was interpreted and summarized in this article.
