Objective: To investigate the efficacy of implantable neuromuscular electrical stimulation system on stress urinary incontinence (SUI) model in female rats. Methods: A total of 21 female infertile SD rats were randomly divided into the control,sham stimulation,and stimulation groups,with 7 rats in each group.All rats received vaginal dilation (VD) to simulate postpartum SUI.One week after VD,the control group was given normal feeding,stimulators were implanted in the pelvic floor muscles of the sham stimulation and stimulation groups.The sham stimulation group received normal feeding for 2 weeks,and the stimulation group received pelvic floor electrical stimulation (PFES) for 2 consecutive weeks.The leak point pressure (LPP) of each rat was measured with cystometry before VD (baseline value),1 week after VD,and 2 weeks after PFES. Results: In the control group and sham stimulation group,LPP increased after 2 weeks of treatment compared with that after 1 week of VD,but it still did not return to the baseline level (P<0.001).In the stimulation group,after 2 consecutive weeks of PFES,LPP increased significantly compared with that 1 week after VD,and returned to the baseline value (P>0.05).There was no significant difference in the LPP baseline values and levels after 1 week of VD among the 3 groups (P>0.05).The LPP in the stimulation group after 2 weeks of PFES was significantly higher than that in the sham stimulation group and stimulation group (P<0.001). Conclusion: The implantable neuromuscular electrical stimulation system is effective in short-term intervention of SUI in female rats,the further studies are needed to confirm the long-term efficacy and safety of the system,the optimal stimulation sites,optimal stimulation parameters,and potential mechanisms of action.

Objective:
To evaluates the association between maternal overweight/obesity during pregnancy and offspring risk of metabolic dysfunction associated steatotic liver disease (MASLD), providing theoretical evidence for early life MASLD prevention.
Methods:
An online search was conducted across ten databases (CNKI, Wanfang, SinoMed, PubMed, Embase, Web of Science, Cochrane Library, PROSPERO, PQDT Global, ScienceDirect) for research literature on the association between maternal overweight/obesity during pregnancy and the development of MASLD in offspring, with the search period spanning from January 2014 to December 2024. Two researchers independently screened literature, extracted data, and assessed study quality. Statistical analysis was performed using R 4.3.3.
Results:
Ten studies involving 10 229 participants were included, comprising 4 cohort studies and 6 case control studies. Cohort studies showed that maternal overweight and obesity significantly increased offspring MASLD risk ( RR=1.59, 95%CI=1.06-2.39, P <0.05), with moderate heterogeneity ( I 2=56.9%, P =0.07). Case control studies indicated a positive association between maternal overweight/obesity during pregnancy and offspring risk of MASLD( OR=2.00, 95%CI=1.68-2.39, P < 0.05), with low heterogeneity ( I 2=48.8%, P =0.08).
Conclusions
Maternal overweight/obesity during pregnancy positively correlates with offspring MASLD risk. Gestational weight management may reduce the risk.

OBJECTIVE To analyze the influencing factors of voriconazole trough concentration and adverse drug reactions (ADR) in renal transplant recipients. METHODS Data from inpatients who received voriconazole and therapeutic drug monitoring in our hospital between January 2022 and August 2023 were retrospectively analyzed. Patients were divided into renal transplant group and non-renal transplant group based on transplantation status. A 1∶1 propensity score matching (PSM) method was used to balance differences in baselines between the two groups. Voriconazole trough concentrations, target attainment rate, clinical efficacy, and ADR were compared between the two groups. Multiple linear regression (backward) was used to analyze the factors influencing voriconazole trough concentrations in the renal transplant group. Univariate analysis and binary Logistic regression were used to identify independent risk factors for ADR in the renal transplant group. RESULTS After PSM, 48 patients were included in each group. There were no statistically significant differences in the mean voriconazole trough concentration, target attainment rate or efficacy rate between the two groups (P>0.05). The total incidence of ADR was significantly higher in the renal transplant group than in the non-renal transplant group (P<0.05). Multiple linear regression analysis showed that age, average daily dose, pulmonary infection, total bilirubin during medication, day-1 loading dose, use of the original drug, concomitant immunosuppressant use, and the occurrence of ADR were factors influencing voriconazole trough concentration in renal transplant patients (P<0.05). Binary Logistic regression analysis showed that abnormal direct bilirubin during medication [OR=7.747, 95%CI (1.334, 45.005), P=0.023] was an independent risk factor for ADR in renal transplant patients receiving voriconazole. CONCLUSIONS Age, average daily dose, pulmonary infection, use of the original drug, day-1 loading dose, total bilirubin during medication, concomitant immunosuppressant use, and the occurrence of ADR are the factors influencing voriconazole trough concentration in renal transplant patients. Furthermore, patients with abnormal direct bilirubin during medication are more susceptible to ADR.

ObjectiveTo investigate the role of proinflammatory cytokines tumor necrosis factor alpha (TNFα) and interleukin-1β (IL-1β) in rostral ventromedial medulla (RVM) in chronic postsurgical pain (CPSP) induced by skin/muscle incision and retraction (SMIR). MethodsSD rats were randomly divided into 5 groups: ① Sham group; ② SMIR group; ③ SMIR+TNFα/IL-1β neutralizing antibody group; ④ SMIR+TNFα/IL-1β group and ⑤ SMIR+vehicle group. 50% paw mechanical withdrawal threshold (MWT) was measured by the up-down method, immunofluroscence was used to detect the TNFα and IL-1β expression and ELISA for the 5-Hydroxytryptamine (5-HT) level. ResultsSMIR elicited persistent nociceptive sensitization, upregulated TNFα and IL-1β expression in RVM neurons and astrocytes. Microinjection of TNFα or IL-1β neutralizing antibody into RVM inhibited the development of nociceptive sensitization and decreased the level of 5-HT in both RVM and spinal dorsal horn. While microinjection of recombinant TNFα or IL-1β into RVM enhanced the development of nociceptive sensitization and increased the level of 5-HT in both RVM and spinal dorsal horn. ConclusionUp-regulation of proinflammatory cytokines in RVM may contribute to SMIR induced CPSP by promoting 5-HT release.

ObjectiveTo investigate the inhibitory effect of Mahuang Xixin Fuzitang on the migration of dendritic cells (DCs) in mice and its underlying mechanism. MethodMouse bone marrow-derived DCs were isolated and cultured. The morphological changes of the cells at different stages were observed under a microscope, and the CD11c+ proportion was detected by flow cytometry to identify DC purity. Cells were treated with Mahuang Xixin Fuzitang (1, 2, 5, 10, 20, 40, 50, 100 g·L-1) for 24 hours, and the effect of Mahuang Xixin Fuzitang on cell proliferation was assessed using the cell counting kit-8 (CCK-8) assay to determine the appropriate concentrations for treatment. After modeling by lipopolysaccharide (LPS) induction, DCs were divided into a blank group, a model group, and Mahuang Xixin Fuzitang groups (2, 4, 8 g·L-1). The expression of surface molecules CD80, CD86, and major histocompatibility complex-Ⅱ (MHC-Ⅱ) were detected by flow cytometry. Transwell chamber assay was used to observe cell migration. The levels of chemokine C-C-primitive receptor 7 (CCR7) and chemokine C-X-C-primitive receptor 4 (CXCR4) on the cell surface were detected by enzyme-linked immunosorbent assay (ELISA). The expression of filamentous actin (F-actin) in the cell microfilament cytoskeleton was detected by immunofluorescence (IF) staining. Real-time quantitative polymerase chain reaction (Real-time PCR) was employed to determine the mRNA expression levels of Ras homolog family member A (RhoA) and Rho-associated coiled-coil containing protein kinase 1 (ROCK1). Western blot analysis was performed to detect the protein expression of RhoA and ROCK1. ResultCompared with the blank group, the model group exhibited significantly higher expression levels of CD80, CD86, and MHC-Ⅱ (P<0.01), a significantly increased number of cells migrating to the lower chamber (P<0.01), and significantly elevated levels of CCR7 and CXCR4 (P<0.05, P<0.01). Additionally, F-actin expression was significantly increased (P<0.01), and both RhoA and ROCK1 mRNA and protein expression levels were significantly higher (P<0.05, P<0.01). Compared with the model group, treatment with Mahuang Xixin Fuzitang (2, 4, 8 g·L-1) for 24 hours resulted in significantly lower expression levels of CD80, CD86, and MHC-Ⅱ (P<0.01), a significantly reduced number of cells migrating to the lower chamber (P<0.05), and significantly decreased levels of CCR7 and CXCR4 (P<0.05, P<0.01). Furthermore, F-actin expression was significantly reduced (P<0.01), and both RhoA and ROCK1 mRNA and protein expression levels were significantly decreased (P<0.05, P<0.01). ConclusionMahuang Xixin Fuzitang can inhibit the migration of DCs in mice, and its mechanism of action may be related to reducing the activity of the Rho/ROCK signaling pathway, thereby affecting changes in the cell cytoskeleton.

Guided by the theory of "kidney generates marrow", the study elaborates the viewpoint that the route of Yin Heel Channel (阴跷脉) is consistent with the "kidney-marrow-brain" axis from the perspective of the circulation of the meridians and the relationship between the zang-fu organs. Accordingly, it is believed that disease of Yin Heel Channel and dysfunction of the "kidney-marrow-brain" axis are the core pathogenesis of children enuresis, and it is elaborated from the following three major aspects, firstly, insufficient kidney essence, dysfunction of the "kidney-marrow-brain" axis, secondly, disease of Yin Heel Channel and deficiency and cold in lower jiao, and thirdly, disease of Yin Heel Channel and loss of nourishment of Chong Vessel. It is proposed to use the mode of "firstly needle, secondly moxibustion, and lastly consolidation" to treat children enuresis. Needle is to adjust yin and yang, warm yang and tonify kidney, and wake up the brain and open the orifices. The acupoints in Yin Heel Channel such as Zhaohai (KI 6), Jiaoxin (KI 8) and confluence points of the eight extraordinary vessels such as Waiguan (TE 5), Zulinqi (GB 41) are used, together with Baihui (GV 20), Yintang (EX-HN 3), Guanyuan (CV 4), Qixue (KI 13), Dazhong (KI 4). Moxibustion is to reinforce healthy qi and warm yang, bank up the root and consolidate the original qi by moxibustion at Shenque (CV 8), Mingmen (GV 4), and Xuanshu (GV 5). Consolidation is to use acupoints application to consolidate the therapeutic effect, and Guanyuan (CV 4) & Pangguangshu (BL 28), Qihai (CV 6) & Zhishi (BL 52), and Shenque (CV 8) & Ciliao (BL 32) are commonly used as the three groups of acupoints to warm the kidney and stop collapse, regulate and tonify the qi and blood.

Objective:To explore the application of medical dialectics combined with problem-oriented teaching based on textbooks in hematology internship teaching.Methods:A total of 100 undergraduate students who practiced in the Department of Hematology of the First Hospital of Jilin University from 2022 to 2023 were selected as the research subjects. Students were randomly assigned to a control group and an observation group, with 50 students in each group. The control group received traditional teaching, while the observation group received medical dialectics combined with textbook-based problem-oriented teaching. We assessed the theoretical and operational scores, classroom performance, comprehensive abilities, and teaching satisfaction of two groups of students using t-test and χ 2 test in SPSS 22.0. Results:The theoretical and operational scores of the observation group were (94.26±5.35) points and (92.68±4.72) points, respectively. The theoretical and operational scores of the control group were (86.16±5.42) points and (81.52±5.28) points, respectively. The differences between the two groups were statistically significant ( P<0.001). The recognition rates were significantly higher by students in the observation group than in the control group ( P<0.05) in terms of improving learning efficiency, self-learning ability, understanding and comprehensive analysis of diseases, problem-solving ability, language and organizational expression ability, integration of theory and practice, clinical thinking ability, and independent thinking ability. The satisfaction with teaching was higher in the observation group than in the control group ( P<0.05) in terms of teaching attitudes, teaching methods, teaching arrangements, practicality of teaching content, clear explanation of teaching theories, and outstanding teaching objectives. Conclusions:The medical dialectics combined with textbook-based problem-oriented teaching can improve the assessment scores of medical students, while helping to cultivate their comprehensive abilities and develop good clinical diagnosis and treatment thinking.

Background::The serum vitamin D level varies widely by population, and studies have linked vitamin D levels with the risk of type 2 diabetes mellitus (T2DM). However, the relationship is inconsistent and the impact of vitamin D on T2DM among East Chinese adults is unclear. The study aimed to investigate the association between serum 25-hydroxyvitamin D (25[OH]D) levels and the risk of T2DM and evaluated whether the association is modified by genetic predisposition.Methods::In the Survey on Prevalence in East China for Metabolic Diseases and Risk Factors (SPECT-China) cohort, 1862 participants free of T2DM at baseline were included. A weighted genetic risk score was calculated with 28 variants associated with T2DM. Hierarchical logistic models were used to examine the association of serum 25(OH)D and genetic risk with T2DM.Results::After a 5-year follow-up, 132 cases of T2DM were documented. We observed no significant association between quartiles of serum 25(OH)D and T2DM risk after multivariable adjustment (χ 2 = 0.571, Pfor trend = 0.426). Compared to those in the lowest quartile of 25(OH)D, the odds ratios (ORs) (95% confidence interval [CI]) for participants with increased quartiles were 1.29 (0.74-2.25), 1.35 (0.77-2.36), and 1.27 (0.72-2.24), respectively. We observed a positive association of glycated hemoglobin (HbA1c) with 25(OH)D at baseline (β = 1.752, P = 0.001) and after follow-up (β = 1.385, P = 0.003), and a negative association of ln conversion homeostasis model assessment (HOMA)-β with 25(OH)D at baseline (β = -0.982, P = 0.021). There was no significant interaction between 25(OH)D and diabetes genetic predisposition on the risk of T2DM (χ 2 = 2.710, Pfor interaction = 0.100). The lowest OR (95% CI) of T2DM was among participants with low genetic risk and the highest quartile of 25(OH)D (0.17 [0.05–0.62]). Conclusion::Serum 25(OH)D may be irrelevant to the risk of incident T2DM among East Chinese adults regardless of genetic predisposition.
