Objective To assess the situation and influencing factors of occupational burnout among the staff at the Center for Disease Control and Prevention (CDC) in Sichuan Province. Methods A total of 1 038 CDC staff members in Sichuan Province were selected as the study subjects using the stratified random sampling method. Occupational burnout of the staff was assessed using the Maslach Burnout Inventory General Survey via an online questionnaire. Results The detection rate of occupational burnout was 42.3% (439/1 038). Binary logistic regression analysis result showed that, after controlling for confounding factors such as education level and alcohol consumption, CDC staffs aged at 20-<31, 31-<41, and 41-<51 years were at higher risk of occupational burnout compared with those ≥51 years (all P<0.05). CDC staffs with 5-<10 or ≥10 years of service had higher occupational burnout risk compared with those with <5 years (both P<0.05). CDC staffs with poor or fair health status, irregular diet, and poor sleep quality had higher risk of occupational burnout compared with those healthy, have regular diet, and good sleep quality (all P<0.05). The risk of occupational burnout increased with higher overtime frequency (all P<0.05). Conclusion Occupational burnout among CDC staffs in Sichuan Province is relatively high. Age, years of service, health status, diet, sleep quality, and overtime frequency are key influencing factors.

OBJECTIVE: To evaluate the early efficacy of local application of tranexamic acid on the osteotomy surface during hallux valgus surgery in reducing postoperative occult blood loss and thus postoperative swelling. METHODS: The data of 40 cases with hallux valgus osteotomy admitted to the Department of Foot and Ankle Surgery of Jishuitan Hospital from July 11, 2022 to October 8, 2022, including 5 males and 35 females were retrospectively analyzed. According to the inclusion and exclusion criteria, 32 cases were finally divided into 16 cases in the observation group (application of tranexamic acid) and 16 cases in the control group (no application of tranexamic acid). The observation group was paired with the control group one by one in accordance with the operation style, and the change in the anterior and posterior diameter of the first metatarsal head, the change in the circumferential diameter of the foot, the length of the first metatarsal midline and the length of the plumbline of the foot measured by postoperative CT were compared between the two groups before and after surgery, in order to evaluate the degree of swelling around the incision after the surgery. The first metatarsal midline and plumb line were measured by reference to the two auxiliary lines that intersect the soft tissue border in the sesamoid bone position to measure the rotation angle of the first metatarsal. A total of three clinicians completed the measurements of these two line segments and interobserver comparisons were performed. RESULTS: By interobserver comparison, the consistency of the length of the midline of the first metatarsal and the plumbline measured by CT was high and could be considered a reliable measurement. After the paired t-test, there was no statistical difference in the amount of changes in the anteroposterior diameter of the first metatarsal before and after surgery between the observation and control groups (P>0.05), and the amount of changes in the circumferential diameter of the foot before and after surgery was smaller in the observation group than in the control group, which was statistically significant (P < 0.05); the length of the midline of the first metatarsal and the plumbline of the foot measured by CT after surgery was smaller in the observation group than in the control group, which was statistically significant (P < 0.05). CONCLUSION Local application of tranexamic acid on the osteotomy surface during hallux valgus osteotomy can relieve postoperative swelling to some extent, which may be related to the fact that tranexamic acid reduces occult blood loss in the postoperative period.

The interest in covalent drugs has resurged in recent decades, spurring the development of numerous specialized computational docking tools to facilitate covalent ligand design and screening. Herein, we present CarsiDock-Cov, a new paradigm distinguishing itself as the first deep learning (DL)-guided approach for covalent docking. CarsiDock-Cov retains the core components of its non-covalent predecessor, leveraging a DL model pretrained on millions of docking complexes to predict protein-ligand distance matrices, along with a dedicated-designed geometric optimization procedure to convert these distances into refined binding poses. Additionally, it incorporates several key enhancements specifically tailored to optimize the protocol for covalent docking applications. Our approach has been extensively validated on multiple public datasets regarding the docking and screening of covalent ligands, and the results indicate that our approach not only achieves comparably improved applicability compared to its non-covalent predecessor, but also exhibits competitive performance against various state-of-the-art covalent docking tools. Collectively, our approach represents a significant advance in covalent docking methodology, offering an automated and efficient solution that shows considerable promise for accelerating covalent drug discovery and design.

Mesangial cell proliferation is an early pathological indicator of diabetic nephropathy (DN). Growing evidence highlights the pivotal role of paired-related homeobox 1 (Prrx1), a key regulator of cellular proliferation and tissue differentiation, in various disease pathogenesis. Notably, Prrx1 is highly expressed in mesangial cells under DN conditions. Both in vitro and in vivo studies have demonstrated that Prrx1 overexpression promotes mesangial cell proliferation and contributes to renal fibrosis in db/m mice. Conversely, Prrx1 knockdown markedly suppresses hyperglycemia-induced mesangial cell proliferation and mitigates renal fibrosis in db/db mice. Mechanistically, Prrx1 directly interacts with the Yes-associated protein 1 (YAP) promoter, leading to the upregulation of YAP expression. This upregulation promotes mesangial cell proliferation and exacerbates renal fibrosis. These findings emphasize the crucial role of Prrx1 upregulation in high glucose-induced mesangial cell proliferation, ultimately leading to renal fibrosis in DN. Therefore, targeting Prrx1 to downregulate its expression presents a promising therapeutic strategy for treating renal fibrosis associated with DN.

Objective:To analyze the effects of preoperative renin-angiotensin system inhibitor (RASi) use on postoperative renal function and short-term and long-term prognosis in patients undergoing coronary artery bypass grafting (CABG).Methods:A retrospective cohort analysis was conducted. Based on the registration study data of CABG patients at Fuwai Hospital, Chinese Academy of Medical Sciences, the clinical data of adult patients who underwent CABG from January 2013 to December 2022 were analyzed. Preoperative use of RASi (PreRASi) was defined as receiving RASi treatment within 48 hours before surgery. Postoperative acute kidney injury (AKI) was defined using the diagnostic criteria of Kidney Disease: Improving Global Outcomes (KDIGO). Demographic characteristics, past medical history, comorbidities, preoperative medication, preoperative laboratory test results, specific information on surgical procedures, and postoperative treatment related data were extracted. The primary endpoint was the incidence of postoperative AKI. Secondary endpoints included in-hospital all-cause mortality and all-cause mortality within the longest follow-up period. According to whether RASi was used before surgery, the patients were divided into PreRASi group and No-PreRASi group. The baseline data of the two groups were balanced by propensity score matching (PSM). Logistic regression model and Cox proportional hazards model were used to assess the correlation between PreRASi and postoperative AKI and clinical outcomes, and analyze the subgroups of hypertension and heart failure with preserved ejection fraction (HFpEF) in the cohort.Results:A total of 33?884 patients who underwent CABG were included, with a mean follow-up duration of (3.0±2.4) years and the longest follow-up duration up to 8.5 years. There were 9?128 cases (26.94%) in the PreRASi group and 24?756 cases (73.06%) in the No-PreRASi group. The incidence of postoperative AKI in the PreRASi group was 47.61% (4?346 cases), compared to 52.37% (12?964 cases) in the No-PreRASi group. Two groups were matched with 5?094 patients each. Compared to the No-PreRASi group, both before and after PSM, PreRASi was associated with a reduction of risk of postoperative AKI [before PSM: odds ratio ( OR) = 0.834, 95% confidence interval (95% CI) was 0.793-0.877, P < 0.001; after PSM: OR = 0.875, 95% CI was 0.808-0.948, P = 0.001]. Subgroup analysis of hypertensive and HFpEF patients showed that PreRASi was associated with a decreased risk of postoperative AKI before and after PSM. The in-hospital mortality for the PreRASi and No-PreRASi groups were 0.61% (56 cases) and 0.49% (121 cases), respectively. Analysis of the overall cohort and subgroups with hypertension and HFpEF showed no correlation between PreRASi and in-hospital mortality or longest follow-up mortality. Conclusion:The perioperative use of RASi can reduce the risk of postoperative AKI in patients undergoing CABG, has a certain renal protective effect, but is not associated with short-term or long-term death risk after surgery.
