OBJECTIVES: Hysterectomy remains the only definitively effective treatment for diffuse uterine leiomyomatosis (DUL). However, no standardized management strategy exists for DUL patients wishing to preserve fertility. This study summarizes and analyzes 5 cases of individualized treatment in DUL patients desiring fertility preservation, aiming to provide a clinical reference for personalized management of similar patients. METHODS: We retrospectively analyzed the clinical data of 5 DUL patients with fertility intentions admitted to the Department of Obstetrics and Gynecology at Third Xiangya Hospital of Central South University. To preserve fertility, individualized treatment plans were selected based on clinical manifestations and fibroid distribution. One patient received high-intensity focused ultrasound (HIFU); one underwent hysteroscopic myomectomy (HM) combined with laparoscopic myomectomy (LRM); one underwent HIFU combined with HM and LRM; one received drug therapy combined with staged HM; and one underwent HIFU combined with staged HM and drug therapy. Treatment outcomes and pregnancy results were analyzed. RESULTS: After treatment, all 5 patients showed marked improvement in menstrual volume or dysmenorrhea symptoms and significant reduction in uterine volume; mild intrauterine adhesions occurred in 3 cases. All 5 patients achieved successful pregnancy. One patient with chronic hypertension developed severe preeclampsia at 34 weeks and underwent cesarean section, while the remaining 4 delivered at term by cesarean section. Three cases of placenta accreta and 2 cases of postpartum hemorrhage occurred. During long-term follow-up, one patient underwent hysterectomy 2 years postpartum due to increased menstrual volume, while the other 4 remained stable. CONCLUSIONS Individualized treatment tailored to DUL patients' conditions can preserve fertility, support successful pregnancy, and achieve favorable pregnancy outcomes.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Objective: To review the current development of artificial intelligence (AI) technology in the field of transfusion medicine. Methods: A systematic search was conducted in the Clarivate Web of Science Database from inception to December 2024 for literature related to AI and transfusion. A total of 4 775 publications were identified. Based on inclusion and exclusion criteria, 133 original studies were ultimately included and analyzed using a narrative synthesis approach. Results: Research on AI in transfusion has surged since 2020 (accounting for 77% of all publications), with China ranking second globally in publication volume. Among the included studies, 69.2% focused on predicting individual transfusion needs, followed by inventory management (8.3%), diagnosis and prediction of adverse transfusion reactions (6.0%), factors influencing transfusion outcomes (5.3%), blood group identification (5.3%), blood quality testing (4.5%), and precise blood volume measurement (1.5%). Additionally, 4.5% of the studies were published in journals with an impact factor greater than 10; 19.5% developed software or applications; 31.5% were multi-center studies; 48.1% utilized decision tree methods, while 31.5% employed neural network approaches; and 14.2% conducted external validation of the algorithms. Conclusion: AI demonstrates significant potential in transfusion risk prediction, decision support, and blood management. However, challenges remain, including limited model generalizability, insufficient algorithm interpretability, and barriers to clinical translation. The deep integration of AI with transfusion medicine will accelerate the advent of precision transfusion era, maximizing blood resource utilization, reducing waste, and ensuring transfusion safety.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To explore the effect of early clinical clerkship training in the early exposure to clinical practice of eight-year program medical students.Methods:Experimental control method was used in this study. A total of 120 eight-year program medical students in the third year of Batch 2014 to 2016 from the Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were selected as the research objects.

Objective:To retrospectively identify the risk factors for postoperative nausea and vomiting (PONV)in the obese patients undergoing laparoscopic sleeve gastrectomy(LSG).Methods:The medical records from the obese patients who underwent elective laparoscopic sleeve gastrectomy from January 2018 to July 2022 were retrospectively collected. PONV was defined according to the use of remedial antiemetics in the nursing record sheet, and the patients were divided into PONV group and non-PONV group according to the occurrence of PONV that required treatment. The logistic regression analysis was used to identify the risk factors for PONV after LSG.Results:A total of 1 264 obese patients were included in this study, and there were 263 patients in PONV group, and the incidence of PONV was 20.81%. According to the results of multifactorial logistic regression analysis, female( OR=1.533, 95% CI 1.007-2.334, P=0.046), higher level of serum alanine aminotransferase concentrations ( OR=1.006, 95% CI 1.002-1.009, P=0.001), higher level of C-reactive protein ( OR=1.013, 95% CI 1.005-1.022, P=0.001), general anesthesia combined with nerve block (general anesthesia combined with TAPB: OR=2.737, 95% CI 1.817-4.121, P<0.001; general anesthesia combined with other nerve block: OR=1.899, 95% CI 1.249-2.889, P=0.003) and intraoperative use of sufentanil ( OR=2.114, 95% CI 1.308-3.415, P=0.002) were independent risk factors for PONV( P<0.05). However, the higher level of serum follicle-stimulating hormone concentrations ( OR=0.941, 95% CI 0.895-0.988, P=0.015), intraoperative use of dexmedetomidine ( OR=0.640, 95% CI 0.417-0.982, P=0.041), and administration of prophylactic antiemetic medication (antiemetic drugs during operation OR=0.669, 95% CI 0.469-0.955, P=0.027; antiemetic drugs after operation OR=0.303, 95% CI 0.182-0.503, P<0.001; antiemetic drugs during and after operation OR=0.215, 95% CI 0.107-0.434, P<0.001) were protective factors for PONV. Conclusions:Female, higher levels of serum alanine aminotransferase and C-reactive protein, general anesthesia combined with nerve block and intraoperative use of sufentanil are independent risk factors for PONV, while higher levels of follicle-stimulating hormone, intraoperative use of dexmedetomidine and administration of prophylactic antiemetic medication are protective factors for PONV among obese patients undergoing LSG.

OBJECTIVES: Intrauterine adhesions (IUA) refers to the adhesions between the myometrium of the uterine cavity, which is secondary to damage to the basal layer of the endometrium due to trauma or infection. The occurrence of IUA is mainly related to intrauterine operations. Hysteroscopic adhesiolysis (HA) is the standard surgical treatment for IUA. But the recurrence rate of IUA after HA is still high. Importantly, endometrium recovery is difficult, resulting in unsatisfied prognosis for moderate to severer IUA patients. Therefore, it is important to take effective primary preventive measures against the etiology to avoid endometrium damage from medical surgery. In this paper, we discuss and analyze predilection and severer sites of intrauterine adhesions, aiming to provide a basis for how to avoid and reduce injuries during intrauterine operations, such as abortion, dilation and curettage. METHODS: In this study, we retrospectively analyzed the surgical videos of patients who underwent HA for the first time from January 2019 to December 2021 in the Third Xiangya Hospital of Central South University so as to assess the area of adhesions and predilection and severer sites of occurrence of adhesions, and we collected 657 patients who underwent HA for the first time, including 81 patients with total IUA and 576 patients with partial IUA. We counted and analyzed the number and composition ratio of partial IUA patients with severer sites of damage to the lateral wall of the uterine cavity and severerr sites of damage to each segment of the uterine cavity. RESULTS: Among 576 patients with partial IUA, there were 60 patients with no significant difference in the degree of adhesions between the right and left sides, 143 patients with severer adhesions on the left side of the uterine cavity, and 373 patients with severer adhesions on the right side of the uterine cavity. There was a difference in the severity of damage of left and right lateral wall. The proportion of patients with severer adhesions on the right side of the uterine cavity (64.8%) was higher than that of patients with adhesions on the left side of the uterine cavity (24.8%), and there was statistically difference (P<0.05). There was 93 patients with severer adhesions at the fundus or bilateral horn of the uterus, 190 patients with severer adhesions at the middle and upper part of the uterine cavity, 245 patients with severer adhesions at the middle and lower part of the uterine cavity and at the endocervix, and 48 patients with no significant difference in the degree of adhesions in each part. The proportion of patients with severer adhesions at the middle and lower part of the uterine cavity and at the endocervix was higher (42.5%) than those with adhesions in the fundus or bilateral horn of the uterus (16.1%) and in the middle and upper part of the uterine cavity (33.0%), and there were statistically differences (both P<0.05). CONCLUSIONS The predilection site of IUA is the lateral wall of the uterine cavity. The severer adhesions is in the right lateral wall of the uterine cavity, the middle and lower segments and the endocervix, which may be related to the operating habits of the surgeon. Therefore, gynecologists should minimize damage to the lateral wall of the uterine cavity, especially the right lateral wall in performing uterine operations (more attention should be paid by right-handed physicians). Besides, we should pay attention to protecting the middle and lower segments of the uterine cavity and the endocervix, avoiding maintaining negative pressure to withdraw the uterine tissue suction tube from the uterine cavity during abortion procedures to minimize damage.

OBJECTIVES: Pelvic floor dysfunction (PFD) seriously affects women's physical and mental health. Pregnancy and childbirth are recognized as high-risk factors for PFD, and studies have shown that vaginal microenvironmental disorders can promote the development of pelvic organ prolapse. In this study, we intend to investigate whether the changes in vaginal microecology during pregnancy affect the pelvic floor function and participate in the development of postpartum PFD, and provide a basis for the prevention and treatment of PFD. METHODS: A total of 358 full-term mothers who delivered in Third Xiangya Hospital, Central South University from November 2019 to April 2020 were selected and underwent review 6 to 8 weeks after delivery. The pelvic floor structures were examined using pelvic floor ultrasound, and ultrasound values were measured at rest and at maximum Valsalva maneuver. One hundred and seventy women with PFD were assigned in a PFD group, and 188 women without PFD were assigned in a control group. The clinical data of all mothers were collected, and the clinical data and the results of microecological testing for vaginal secretions after 36 weeks of gestation and before delivery were compared between the 2 groups. The correlation of PFD with leucorrhoea cleanliness, lactobacillus level, bacterial vaginosis (BV), and vulvovaginal candidiasis (VVC) was analyzed, and logistic regression analysis was used to screen for independent risk factors for PFD. RESULTS: The incidences of VVC, BV, Lactobacillus vaginalis deficiency, and leucorrhoea cleanliness ≥III° were all higher in the PFD group than those in the control group (P<0.05). Among them, leukocyte cleanliness ≥III°and lack of Lactobacilli in the vagina were independent risk factors for the development of PFD, while VVC and BV were not independent risk factors for the development of PFD. CONCLUSIONS Postpartum PFD is related to vaginal microecological imbalance in late pregnancy, among which Lactobacillus vaginalis deficiency and leucorrhoea cleanliness ≥III° are independent risk factors for the occurrence of PFD. Therefore, pregnant women with Lactobacillus vaginalis deficiency and leucorrhoea cleanliness ≥III° in late pregnancy should pay attention to the occurrence of postpartum PFD, and early diagnosis and effective intervention of postpartum PFD should be enhanced.
