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.

OBJECTIVES: To investigate the mechanism of DDX17 for regulating proliferation and migration of pulmonary arterial smooth muscle cells (PASMCs) during the development of pulmonary hypertension (PH). METHODS: In murine PASMCs cultured under normoxic or hypoxic conditions, the effects of transfection with si-Ddx17 and insulin treatment, alone or in combination, on cell proliferation and migration were evaluated using Ki-67 immunofluorescence staining, scratch assay and Transwell assay. Western Blotting was performed to detect the changes in protein expression levels of DDX17, 4EBP1, S6, p-4EBP1, and p-S6. In a mouse model of PH induced by intraperitoneal injection of monocrotaline (MCT), the changes in pulmonary vasculature were examined using HE staining following tail vein injection of AD-Ddx17i. RESULTS: The PASMCs in hypoxic culture exhibited significantly enhanced cell proliferation and migration and protein expressions of p-4EBP1 and p-S6, and these changes were obviously reversed by transfection with si-Ddx17. Treatment with insulin significantly attenuated the effect of si-Ddx17 against hypoxic exposure-induced changes in PASMCs. In the mouse model of MCT-induced PH, transfection with AD-Ddx17i obviously alleviated pulmonary vascular stenosis and intimal hyperplasia. CONCLUSIONS The expression of DDX17 is elevated in hypoxia-induced PASMCs and PH mice, and silencing DDX17 significantly inhibits PASMC proliferation and migration in vitro and pulmonary vascular remodeling in PH mice by reducing mTORC1 activity.

OBJECTIVE: The present study evaluated the effects of deep acupuncture at Weizhong acupoint (BL40) on bladder function and brain activity in a rat model of overactive bladder (OAB), and investigated the possible mechanisms around the acupuncture area that initiate the effects of acupuncture. METHODS: Adult female Sprague-Dawley rats were randomly divided into six groups, comprising a control group, model group, group treated with deep acupuncture at BL40, group treated with shallow acupuncture at BL40, group treated with acupuncture at non-acupoint next to BL40, and group treated with acupuncture at Xuanzhong (GB39). Urodynamic evaluation was used to observe the urination, and functional magnetic resonance imaging was used to observe the brain activation. The mechanism of acupuncture at BL40 in regulating bladder function was explored by toluidine blue staining and enzyme-linked immunosorbent assay, and the mechanism was verified by stabilizing mast cells (MCs) or blocking tibial nerve. RESULTS: Deep acupuncture at BL40 significantly increased the intercontraction interval in OAB rats and enhanced the mean amplitude of low frequency fluctuation of primary motor cortex (M1), periaquaductal gray matter (PAG), and pontine micturition center (PMC). It also increased the zero-lag functional connectivity between M1 and PAG and between PAG and PMC. Shallow acupuncture at BL40 and acupuncture at non-acupoint or GB39 had no effect on these indexes. Further studies suggested that deep acupuncture at BL40 increased the number and degranulation rate of MCs as well as the contents of 5-hydroxytryptamine, substance P, and histamine in the tissues around BL40. Blocking the tibial nerve by lidocaine injection or inhibiting MC degranulation by sodium cromoglycate injection obstructed the effects of acupuncture on restoring urinary function and modulating brain activation in OAB rats. CONCLUSION Deep acupuncture at BL40 may be more effective for inhibiting OAB by promoting degranulation of MCs around the acupoint and stimulating tibial nerve, thereby regulating the activation of the brain area that controls the lower urinary tract.

To summarize the clinical experience of Professor WANG Jie in treating palpitation using the method of tonifying the kidneys and invigorating blood. It is believed that kidney yang deficiency and heart vessel stasis are the key pathogenesis of palpitation， and it is advocated to treat palpitation by tonifying the kidney and invigorating the blood. Meanwhile，the methods of draining water， dissolving phlegm， and fortifying the spleen to supplement the blood should be applied. For palpitation with kidney yang deficiency and heart vessel stasis with upward water， the treatment could use self-prescribed Bushen Huoxue Lishui Formula （补肾活血利水方）； for palpitation with phlegm obstruction in blood vessel， the treatment could use self-prescribed Bushen Huoxue Huatan Formula （补肾活血化痰方）； for palpitation with spleen yang deficiency， the treatment could use self-prescribed Bushen Huoxue Jianpi Formula （补肾活血健脾方）.

Objective:To investigate the overall drug resistance, drug resistance trend and distribution of drug resistance mutation sites in human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients with antiviral therapy failure in Yunnan Province.Methods:The demographic data and genotype drug resistance of HIV/AIDS population with antiviral therapy failure in Yunnan Province from January 2021 to December 2023 were collected and analyzed by cross-sectional investigation. Statistical analyses were performed using chi-square test.Results:Among 15 159 HIV/AIDS patients, 12 215 cases tested positive by amplification. The circulating recombinant form (CRF) 08_BC was the predominant genetic subtype, accounting for 54.97%(6 714/12 215), followed by CRF01_AE (16.14%(1 972/12 215)) and CRF07_BC (14.48% (1 769/12 215)). When the viral load was ≥200 to <1 000 copies/mL, the incidence of drug resistance was 21.48%(99/461). When it was ≥1 000 to <10 000 copies/mL, the incidence was 51.29%(2 867/5 590). When it was ≥10 000 to <100 000 copies/mL, the incidence was 69.39% (3 979/5 734). When it was ≥100 000 copies/mL, the incidence was 81.86%(352/430). A total of 7 297 drug resistant cases were detected, with a drug resistance rate of 59.74% (7 297/12 215), thus the estimated drug resistance incidence rate among the antiviral treated population in Yunnan Province was 2.00% (7 297/364 238). From 2021 to 2023, the annual drug resistance rates among patients were 60.71%(2 554/4 207), 60.28%(1 671/2 772), and 58.67% (3 072/5 236), respectively, with no statistically significant difference ( χ2=4.47, P=0.107). Among the population with antiviral therapy failure, the drug resistance rates of non-nucleoside reverse transcriptase inhibitor (NNRTI), nucleoside reverse transcriptase inhibitor (NRTI), and protease inhibitor (PI) were 93.70%(6 837/7 297), 44.10%(3 218/7 297) and 5.15%(376/7 297), respectively. The mutation sites with the highest frequencies among the three classes of drugs including NRTI, NNRTI and PI were M184V/I (46.13%(2 123/4 602)), K103N/S (37.14%(2 648/7 129)), L33F (15.50%(82/529)) and M46I/L (15.50%(82/529)), respectively. Analysis of the degree of drug resistance showed that among NNRTI drugs, nevirapine (49.01%(5 987/12 215)) and efavirenz (48.00%(5 863/12 215)) had the highest drug resistance rates, followed by emtricitabine (23.59%(2 882/12 215)) and lamivudine (23.58%(2 881/12 215)) among NRTI drugs. Conclusions:Among HIV/AIDS patients with antiviral therapy failure in Yunnan Province from 2021 to 2023, CRF08_BC is the main genetic subtype. The drug resistance rate of patients increases with the increase of HIV-1 viral load. There is no significant change in the drug resistance rate from 2021 to 2023. NNRTI has the highest drug resistance rate, followed by NRTI, and PI has the lowest. The main mutation sites are M184V/I for NRTI, K103N/S for NNRTI, and M46I/L and L33F for PI. The drug resistance rates of nevirapine, efavirenz, emtricitabine and lamivudine are relatively high.

Objective:To explore the expression of nectin-4 and vanin-1 in esophageal squamous cell carcinoma(ESCC)and its influence on the malignant biological behaviors of ESCC cells,as well as the underlying mechanisms.Methods:Transcriptome sequencing combined with GO and KEGG enrichment analysis was used to identify the downstream target gene(vanin-1)regulated by nectin-4.The mRNA expression of vanin-1 in ESCC tissues was studied using the Timer2.0 database,and the mRNA and protein expression of vanin-1 in normal esophageal epithelial HET-1 and ESCC cells was detected by qPCR and Western blot,identifying ESCC KYSE-410 and KYSE-510 cells with the most significant differential expression.The expression of vanin-1 in KYSE-410 and KYSE-510 cells was knocked down using siRNA.The effects of vanin-1 knockdown on cell proliferation,migration,and invasion were measured using CCK-8 assay,wound healing assay,and Transwell chamber assay.Furthermore,KEGG and GO enrichment analyses were conducted for vanin-1-related signaling pathways.Immunohistochemistry was performed to compare the expression of vanin-1 between ESCC tissues and adjacent non-tumor tissues.Results:Timer2.0 database analysis and qPCR results showed that vanin-1 was highly expressed in both ESCC tissues and cell lines(both P<0.01).WB assay also confirmed high expression of vanin-1 protein in ESCC cells(P<0.01).siRNA successfully knocked down vanin-1 expression in KYSE-410 and KYSE-510 cells.Knockdown of vanin-1 significantly inhibited the proliferation,migration,and invasion capabilities of KYSE-410 and KYSE-510 cells(P<0.05 or P<0.01 or P<0.001 or P<0.000 1).KEGG and GO enrichment analysis suggested that vanin-1 might function through pathways related to pantothenic acid and coenzyme A synthesis metabolism.Immunohistochemistry results indicated that vanin-1 was highly expressed in ESCC tissues(P<0.000 1).Conclusion:Vanin-1 is highly expressed in ESCC tissues and promotes the proliferation,migration,and invasion of KYSE-410 and KYSE-510 cells through the nectin-4/vanin-1 axis.Targeting vanin-1 might offer a new therapeutic strategy for ESCC.

Objective To explore the value of carotid pulse wave combined with urinary transferrin(TRF)and β2-microglobulin(β2-MG)in the evaluation of renal injury in patients with hyperten-sive nephropathy.Methods A total of 30 patients with hypertensive nephropathy,30 patients with simple hypertension and 90 patients with non-hypertensive nephropathy who were admitted to our hospital between May 2021 and April 2024,and 30 healthy individuals(control group)who taking physical examination during same period were enrolled and assigned into corresponding groups,respectively.According to the severity of renal injury,the 120 patients from the hyperten-sive nephropathy group and non-hypertensive nephropathy group were divided into normal group(28 cases),mildly injured group(36 cases),moderately injured group(31 cases)and severely in-jured group(25 cases).The carotid pulse wave indicators[pulse wave velocity at beginning of the systole(PWV-BS),pulse wave velocity at ending of the systole(PWV-ES)],and urinary TRF and β2-MG levels were detected and compared in above groups.ROC curves were plotted to ana-lyze the diagnostic values of these indicators in hypertensive nephropathy.The relationship be-tween the above indicators and the severity of renal injury was analyzed with sequential multivari-ate logistics regression analysis.Results There were significant differences in PWV-BS,PWV-ES,and urinary TRF and β2-MG levels among the hypertensive nephropathy group,non-hyperten-sive nephropathy group,hypertension group and control group(P＜0.01).ROC curve analysis showed that the AUC value of the four indictors combined together in the diagnosis of hyperten-sive nephropathy was 0.907,which was statistically greater than that of single indicator alone(0.774,0.743,0.728,0.749,P＜0.01).Obvious differences were also observed in PWV-BS,PWV-ES,and urinary TRF and β2-MG levels among the severely,moderately and mildly injured groups and normal group(P＜0.01).Sequential multivariate logistics regression analysis indicated that PWV-BS(OR=1.824,95％CI:1.272-2.616,P=0.001),PWV-ES(OR=1.910,95％CI:1.268-2.877,P=0.002),and urinary TRF(OR=2.442,95％CI:1.485-4.018,P=0.001)and β2-MG levels(OR=2.807,95％CI:1.580-4.984,P=0.001)were influencing factors of renal injury severity in the renal injured patients.Conclusion Carotid pulse wave combined with urinary TRF and β2-MG can be applied in auxiliary diagnosis of hypertensive nephropathy,and they are correla-ted with the severity of renal injury.
