Objective: To investigate the current status of benefit finding among young and middle-aged patients with type 2 diabetes mellitus (T2DM) and analyze its influencing factors, so as to provide a reference for improving the level of benefit finding in this population. Methods: From November 2022 to May 2023, young and middle-aged patients with T2DM aged 18-59 years hospitalized in the endocrinology departments of 2 tertiary hospitals in Hengyang City, Hunan Province were selected as survey subjects by a convenience sampling method. Basic demographic information was collected using a general questionnaire survey. Benefit finding, resourcefulness, and stigma were evaluated using the Benefit Finding Scale, the Chinese Version of the Resourcefulness Scale, and the Type 2 Diabetes Stigma Assessment Scale, respectively. A multiple linear regression model was used to analyze the influencing factors of benefit finding among young and middle-aged patients with T2DM. Results: A total of 305 young and middle-aged patients with T2DM were investigated, including 222 males (72.79%) and 83 females (27.21%). There were 231 cases aged 45-59 years, accounting for 75.74%. The scores for benefit finding, resourcefulness, and stigma were (42.86±6.06), (75.12±11.30), and (41.20±10.10), respectively. Multiple linear regression analysis showed that young and middle-aged patients with T2DM who were male (β′=0.088), aged 18-<45 years (β′=0.083), absence of diabetes complications (β′=0.124), and had higher resourcefulness scores (β′=0.679) had higher levels of benefit finding, while patients with higher stigma scores (β′=-0.097) had lower levels of benefit finding. Conclusion The level of benefit finding among young and middle-aged patients with T2DM was moderate, and was related to gender, age, diabetes complications, resourcefulness, and stigma.

Objective:To evaluate the safety and efficacy of using small and ultra-small sized grafts for in situ auxiliary liver transplantation in the treatment of portal hypertension.Methods:A prospective single-arm cohort study was conducted. Patients who underwent liver transplantation at Beijing Friendship Hospital from December 2014 to July 2025 were included. Intraoperative portal vein pressure was routinely monitored, with the target regulation for portal vein blood flow set at<15 mmHg (1 mmHg=0.133 kPa) and follow-up continued until September 2025. The primary endpoints were the patient's status and graft survival. The secondary endpoints were small-for-size syndrome and perioperative complications. The small-for-size syndrome was graded according to the 2023 International Liver Transplantation Society consensus statement.Results:A total of 33 cases were enrolled. Among them, 22 had ultra-small size grafts, 11 had small-size grafts, 28 had living donor grafts, and five had split grafts. The graft-to-recipient weight ratio in living donor liver transplantation was 0.31%～0.79%, while in split liver transplantation it was 0.45%～1.02%. Intraoperative portal vein pressure of ≥15 mmHg was observed in 11 cases, who underwent portal vein blood flow adjustment via splenic artery ligation (2 cases), partial splenectomy (8 cases), and/or restrictive portocaval shunting (1 case), after which all patients achieved the target portal vein pressure. All cases completed at least one month of follow-up, with 28 cases following for more than one year, and the median follow-up period was 36.5 months. Early-stage postoperative small-for-size syndrome occurred in eight cases (24.2%, 8/33), all classified as grade A, with improvements following supportive treatment. Severe complications (Clavien-Dindo≥Ⅲ) occurred in three cases (9.1%, 3/33). The one-year survival rate was 92.9% (26/28). The overall survival rate at the end of follow-up was 90.9% (30/33). No patients experienced graft loss or death due to small-for-size syndrome. Graft tissue tested negative for hepatitis B core antibody and covalently closed circular DNA, and hepatitis B surface antigen seroconversion was achieved following second-stage residual liver resection and under a combined strategy of potent nucleos(t)ide analogs and hepatitis B immunoglobulin in ten cases of hepatitis B-related disease.Conclusions:With standardized portal vein blood flow monitoring and individualized portal vein blood flow adjustment, in situ auxiliary liver transplantation can safely and effectively use small and even ultra-small sized grafts, thereby significantly expanding graft sources and ensuring donor and recipient safety. These findings warrant further validation and promotion in multicenter controlled studies.

Objective To analyze bedside radiation dose rates for interventional surgery operators in Guangdong Province, examine dose distribution patterns, and identify potential weaknesses in radiation protection, and to provide guidance for optimizing radiation monitoring and protection measures. Methods A total of 209 digital subtraction angiography devices measured in Guangdong Province between 2017 and 2024 were used as the research objects. The first and second operator positions were set at 30 cm and 90 cm horizontally from the X-ray tube focal point, respectively. Monitoring points were set up at 155, 125, 105, 80, and 20 cm above the ground. Results The median bedside radiation dose rate for interventional surgery operators in Guangdong Province was 83.0 (3.9, 1044.0) μSv/h, indicating instances of exceeding standard limits. The overall dose rates under the old and new standards were 29.8 (3.9-346.5) μSv/h and 114.0 (4.0-1044.0) μSv/h respectively. Results for both standards showed a higher dose rate at the second than the first operator position. The dose rates at the heights of 105 cm (abdomen), 125 cm (chest), and 155 cm (head) were higher in the second operator position than in the first operator position. Additionally, 71.5% and 56.8% of the highest dose rate points under the new and old standards, respectively, were concentrated at 105 cm (abdomen), 125 cm (chest) and 155 cm (head) in the second operator position. Conclusion The principle of protection optimization should be followed, auxiliary protective facilities should be placed correctly, and attention should be paid to the protection of the second surgery operator position, especially above the abdomen. The dose rate results under the new standard were lower than those under the old standard, suggesting that the measurement method may overestimate radiation exposure at the secondary operator position.

OBJECTIVE: To assess the efficacy of Qingda Granule (QDG) in ameliorating hypertension-induced cardiac damage and investigate the underlying mechanisms involved. METHODS: Twenty spontaneously hypertensive rats (SHRs) were used to develope a hypertension-induced cardiac damage model. Another 10 Wistar Kyoto (WKY) rats were used as normotension group. Rats were administrated intragastrically QDG [0.9 g/(kg•d)] or an equivalent volume of pure water for 8 weeks. Blood pressure, histopathological changes, cardiac function, levels of oxidative stress and inflammatory response markers were measured. Furthermore, to gain insights into the potential mechanisms underlying the protective effects of QDG against hypertension-induced cardiac injury, a network pharmacology study was conducted. Predicted results were validated by Western blot, radioimmunoassay immunohistochemistry and quantitative polymerase chain reaction, respectively. RESULTS: The administration of QDG resulted in a significant decrease in blood pressure levels in SHRs (P<0.01). Histological examinations, including hematoxylin-eosin staining and Masson trichrome staining revealed that QDG effectively attenuated hypertension-induced cardiac damage. Furthermore, echocardiography demonstrated that QDG improved hypertension-associated cardiac dysfunction. Enzyme-linked immunosorbent assay and colorimetric method indicated that QDG significantly reduced oxidative stress and inflammatory response levels in both myocardial tissue and serum (P<0.01). CONCLUSIONS Both network pharmacology and experimental investigations confirmed that QDG exerted its beneficial effects in decreasing hypertension-induced cardiac damage by regulating the angiotensin converting enzyme (ACE)/angiotensin II (Ang II)/Ang II receptor type 1 axis and ACE/Ang II/Ang II receptor type 2 axis.

Objective To explore the correlation between glycemic control and complexity of drug treatment regimens in elderly patients with type 2 diabetes mellitus.Methods A retrospective,cross-sectional study was conducted to collect the elderly patients with type 2 diabetes mellitus who were hospitalized in the Department of Endocrinology at the Geriatric Hospital of Nanjing Medical University from June 2022 to December 2024.The clinical characteristics and medication compliance of the patients were recorded through pharmaceutical consultations.The medication regimen complexity index(MRCI)and diabetes-specific medication regimen complexity index(D-MRCI)were calculated for each patient.Patients were divided into the target-achieving group and the non-target-achieving group based on whether their blood glucose met the criteria.Univariate analysis and multivariate Logistic regression analysis were used to identify the factors associated with adequate blood glucose control.Results A total of 152 patients were included,123(80.9%)had poorer glycemic control,31.6%exhibited good medication adherence,and 76.3%demonstrated good adherence to diabetes medications.The mean total MRCI score was(25.90±8.63),while the median D-MRCI score was 9.00(5.25,11.75),with 44.7%of patients classified as having high D-MRCI scores(D-MRCI>9).The results of Spearman correlation analysis indicated that the number of medications used by patients was highly correlated with the MRCI score(r=0.899,P<0.001),while the number of diabetes medications used was highly correlated with the D-MRCI score(r=0.705,P<0.001).Univariate analysis results revealed that high complexity diabetes medication regimen,duration of diabetes,the number of types of antidiabetic drugs,and the number of injectable antidiabetic medications were associated with glycemic control(P≤0.05).Multivariate analysis results showed that,high diabetes medication complexity was an independent risk factor for inadequate blood glucose control[OR=4.119,95%CI(1.121,15.139),P=0.033].Conclusion Higher D-MRCI(>9)was associated with poorer glycemic control.Simplifying medication regimens and optimizing medication management strategies may improve patient outcomes.

Aim To investigate the biological function and molecular mechanisms of piRNA-823 in the phenotypic transformation of human umbilical vein endothelial cells(HUVEC)induced by high glucose.Methods HUVEC were incubated in high glucose(33.3 mmol/L)culture medium for 72 h.The relative expression levels of piR-NA-823 were detected by RT-qPCR,the expression changes of endothelial cell markers,mesenchymal cell markers and proteins related to transforming growth factor-β1(TGF-β1)signaling pathway were detected by Western blot,the changes of cell migration ability were evaluated by scratch and Transwell assays,the formation of new angiogenesis were assessed through angiogenesis experiments.piRNA-823 mimic(overexpression of piRNA-823)were transfected into HUVEC to analyze their effects on high glucose induced endothelial-mesenchymal transition(EndMT)and angiogenesis.Further in-tervention was performed using TGF-β1 activator(SRI011381)and inhibitor(SB525334)to verify whether piRNA-823 ex-erts its effect by regulating the TGF-β1/Smad2/3 signaling pathway.Results piRNA-823 mimic significantly inhibited the viability,proliferation,migration and angiogenesis of HUVEC induced by high glucose.The piRNA-823 mimic inhibited high glucose induced EndMT in HUVEC,characterized by upregulation of endothelial cell markers and downregulation of mesenchymal cell markers.Scratch experiments,Transwell experiments and angiogenesis experiments further confirmed that piRNA-823 mimic could effectively reverse high glucose induced HUVEC proliferation,migration a-bility enhancement,and increase in the number of new angiogenesis.Mechanistic studies revealed that the TGF-β1 acti-vator partially reversed the protective effect of piRNA-823 mimic,whereas the TGF-β1 inhibitor enhanced its effect,sug-gesting that piRNA-823 exerts its regulatory role by suppressing the activation of the TGF-β1/Smad2/3 signaling pathway.Conclusion piRNA-823 significantly inhibits high glucose induced EndMT,proliferation,migration and angiogenesis in HUVEC by suppressing the activation of TGF-β1/Smad2/3 signaling pathway.
