OBJECTIVE To investigate the improvement effect and potential mechanism of Qingxue xiaozhi jiangtang formula on insulin resistance (IR) in type 2 diabetes mellitus (T2DM) rats. METHODS T2DM rat model was established by intraperitoneal injection of 30 mg/kg streptozotocin combined with high-fat and high-sugar diet. The rats were randomly divided into normal control group, model group, Qingxue xiaozhi jiangtang formula low-dose and high-dose groups (6.525, 13.05 g/kg, calculated by raw material) and metformin group (positive control, 0.18 g/kg), with 8 rats in each group. Administration groups were given relevant medicine intragastrically; normal control group and model group were given constant volume of normal saline intragastrically, once a day, for consecutive 6 weeks. Body mass and fasting blood glucose (FBG) were determined, and oral glucose tolerance test was conducted. Serum fasting insulin (FINS) level was measured to calculate the insulin resistance index (HOMA-IR) and insulin sensitivity index (ISI). Additionally, the level of serum lipids, liver function, oxidative stress indicators and inflammatory factors were assessed. The phosphorylation levels of kinase R-like endoplasmic reticulum kinase (PERK) and forkhead box O1 (FOXO1) protein in liver tissue of rats were determined. RESULTS Compared with model group, the body weight, ISI, the levels of high-density lipoprotein cholesterol and superoxide dismutase were increased significantly in Qingxue xiaozhi jiangtang formula high-dose group and metformin group (P<0.05); FBG, blood glucose level at 120 minutes of glucose loading, area under the curve of glucose, FINS, HOMA-IR, low-density lipoprotein cholesterol, total cholesterol, triglyceride, alanine transaminase, aspartate transaminase, alkaline phosphatase, malondialdehyde, interleukin-6, tumor necrosis factor-α, and C-reactive protein levels were significantly reduced (P< Δ0.05); the pathological damage of liver tissue had significantlyimproved, and the phosphorylation levels of PERK and FOXO1 proteins in liver tissue were significantly decreased (P<0.05). CONCLUSIONS Qingxue xiaozhi jiangtang formula can regulate glucose and lipid metabolism, inflammation factor and oxidative stress levels, and alleviate insulin resistance in T2DM rats. Its mechanism of action may be related to the inhibition of the PERK/FOXO1 signaling pathway.

Sensorineural hearing loss is one of the most common sensory disorders. In recent years, auditory neuropathy spectrum disorders caused by mutations in the OTOF gene have garnered significant attention worldwide, marking it as the first deafness gene with breakthroughs in gene therapy. Most patients with OTOF gene mutations present with stable, congenital, or prelingual onset of hearing loss, which can range from severe to profound and even complete hearing loss. However, a minority of patients may exhibit mild to moderate progressive hearing loss or temperature-sensitive hearing loss. This review further explores the genotype-phenotype relationship of the OTOF gene based on reported cases in China and abroad. Additionally, we analyze the characteristics of the natural history of OTOF gene mutations within the Chinese population. This study aims to provide a reference for the clinical diagnosis, evaluation, and treatment of hearing loss associated with OTOF gene mutations.

Detrusor-sphincter dyssynergia (DSD) is a lower urinary tract dysfunction syndrome caused by disorders of the neural regulatory pathways for micturition. Its core feature is that the urethral sphincter fails to relax coordinately during detrusor contraction; instead, the persistent abnormal contraction leads to a series of severe complications such as dysuria, elevated intravesical pressure, and upper urinary tract damage.DSD is common in patients with central nervous system lesions, such as spinal cord injury and multiple sclerosis. This paper systematically reviews the latest research progress on the neural mechanisms of DSD, including ① loss of central regulation and excessive excitation of the spinal cord center, i.e., the loss of supraspinal inhibition leading to sacral spinal reflex hyperactivity; ② imbalance of key neurotransmitters and receptors, involving excessive glutamatergic excitation, weakened gamma-aminobutyric acid ergic/glycinergic inhibition, and the involvement of purinergic and endocannabinoid systems; ③ neuroimmunity and inflammatory response, where the activation of microglia and astrocytes after spinal cord injury releases pro-inflammatory factors, exacerbating neuronal excitability and circuit remodeling; ④ peripheral nerve and gut-bladder axis mechanisms, where sphincter structural remodeling and the gut microbiota-neuroimmunity crosstalk form a vicious cycle. The paper focuses on the sacral Onuf's nucleus as the“core hub”and key therapeutic target of DSD, discussing the central role of its dysfunction in the occurrence of synergistic disorders. In terms of therapeutic strategies, the paper summarizes existing traditional methods, such as drugs, botulinum toxin injection and neuromodulation, and envisions the cutting-edge directions of targeted intervention, such as precise strategies including gene therapy and neurotrophic support, as well as the challenges faced in clinical translation. Finally, the paper discusses the application prospects of precision medicine and artificial intelligence in the diagnosis and treatment of DSD, including precise classification based on multi-omics data, artificial intelligence-assisted recommendation of individualized treatment plans, and the development of dynamic closed-loop regulation systems. This paper aims to provide a theoretical basis and research direction for in-depth understanding of the neural mechanisms of DSD, and to promote the precise diagnosis, treatment and neural function remodeling.

Objective:To explore the association between frailty index (FI) and the risk for cardiovascular disease (CVD) in adults in Inner Mongolia Autonomous Region, and provide new evidence for the prevention of CVD in adults in Inner Mongolia Autonomous Region.Methods:The FI was constructed by using the data from a prospective cohort with a sample size of 25 055 individuals in 6 years of follow-up, and the prevalence of frailty in adults in Inner Mongolia Autonomous Region was described by the FI, and Cox proportional hazard regression model was used to evaluate the association between the FI and the incidence of CVD in adults in Inner Mongolia Autonomous Region.Results:The FI of the study population was 0.24±0.09. The population in the pre-frail (FI: 0.21-0.27) and frail (FI≥0.28) phases had increased risk for CVD compared to non-frail (FI≤0.20) population [pre-frail: hazard ratio ( HR)=1.232, 95% CI: 1.127-1.347; frail phase: HR=1.418, 95% CI:1.299-1.548]. For every 0.10 increase in FI, the risk for cardiovascular disease increased by 20.3% ( HR=1.203,95% CI:1.156-1.252). Conclusions:In this study, we constructed a FI, which can suggest the risk for CVD. As the increase of frailty degree, the risk for CVD increases.

Objective:Clarify the correlation between the Centralized Drug Volume-based Purchasing Policy,changes in physical&mental health status,and health inequalities among the older adults,as well as exploring whether this correlation differs between urban and rural areas so as to determine the role played by the total cost of healthcare.Methods:Based on CFPS 2018 and 2020,DID and PSM-DID were used to verify the impact of the Centralized Drug Volume-based Purchasing Policy on physical&mental health status and health inequalities of the elderly in urban and rural China.Three-step method and Sobel test were used to verify the mediating effect of total medical costs.Results:The pilot effect of the Centralized Drug Volume-based Purchasing Policy was first realized among the urban elderly population,promoting their physical and mental health through the intermediary mechanism of reducing the total medical costs,but for the time being did not show a significant correlation with health inequalities within this group.Among the rural elderly population,none of the three dependent variables was significant(P>0.1).Conclusion:The underlying logic of the Centralized Drug Volume-based Purchasing Policy is right,but its future reform should focus on the rural elderly group,and consider the fairness of the effect within the group and between urban and rural areas,so as to improve the health level of the whole society in the longer term.
