OBJECTIVE: To observe the effect of acupuncture at Jiaji (EX-B2) points on upper limb motor dysfunction in patients after stroke. METHODS: A total of 62 patients with upper limb motor dysfunction after stroke were randomly assigned to an observation group (n=31, 3 cases dropped out) and a control group (n=31, 2 cases dropped out). Both groups received routine medical treatment and rehabilitation training. The control group was treated with conventional acupuncture at the affected side's Jianyu (LI15), Quchi (LI11), Shousanli (LI10), Huantiao (GB30), Yanglingquan (GB34), and Zusanli (ST36) etc. On this basis, the observation group received additional acupuncture at the affected side's Jiaji points from C₄ to T₅. Treatment was administered once daily, five times a week, for four weeks. Motor evoked potential (MEP) latency and amplitude of the abductor pollicis brevis and abductor digiti minimi, Fugl-Meyer assessment for upper extremity (FMA-UE), and Wolf motor function test (WMFT) scores were compared before and after treatment in the two groups. RESULTS: After treatment, both groups showed increased MEP amplitudes and decreased latencies of the abductor pollicis brevis and abductor digiti minimi (P<0.05), as well as increased FMA-UE and WMFT scores (P<0.05); the observation group had greater MEP amplitudes, shorter latencies, and higher FMA-UE and WMFT scores compared to the control group (P<0.05). CONCLUSION Acupuncture at Jiaji (EX-B2) points could enhance the excitability of upper limb motor neural pathways in upper limb motor dysfunction after stroke patients, thereby promoting motor function recovery of the upper limb.

Idiopathic pulmonary fibrosis (IPF) is a progressive disease lacking effective therapy. Metformin, an antidiabetic medication, has shown promising therapeutic properties in preclinical fibrosis models; however, its precise cellular targets and associated mechanisms in fibrosis resolution remain incompletely defined. Most research on metformin's effects has focused on mesenchymal and inflammatory responses with limited attention to epithelial cells. In this study, we utilized Sftpc lineage-traced and Fgfr2b conditional knockout mice, along with BMP2/PPARγ and AMPK inhibitors, to explore metformin's impact on alveolar epithelial cells in a bleomycin-induced pulmonary fibrosis model and cell culture. We found that metformin increased the proliferation and differentiation of alveolar type 2 (AT2) cells, particularly the recently identified injury-activated alveolar progenitors (IAAPs)-a subpopulation characterized by low SFTPC expression but enriched for PD-L1. Single-cell RNA sequencing revealed a reduction in apoptosis among mature AT2 cells. Interestingly, metformin's therapeutic effects were not significantly affected by BMP2 or PPARγ inhibition, which blocked the lipogenic differentiation of myofibroblasts. However, Fgfr2b deletion in Sftpc lineage cells significantly impaired metformin's ability to promote fibrosis resolution, a process linked to AMPK signaling. In conclusion, metformin alleviates fibrosis by directly activating AT2 cells, especially the IAAPs, through a mechanism that involves AMPK and FGFR2b signaling, but is largely independent of BMP2/PPARγ pathways.

Objective To investigate the relationship between the expression of platelet autophagy related factors and peritoneal metastasis of gastric cancer.Methods The data of 360 patients with gastric cancer who underwent surgery in Hunan Provincial People's Hospital from January 2021 to May 2023 were reviewed.Patients were divided into non-peritoneal metastasis group(n=322)and peritoneal metastasis group(n=38)according to whether peritoneal metastasis occurred or not.The following information was collected:patient's personal information(i.e.age,sex,body mass index)and tumor characteristics(i.e.location,size,pathological type,histopathological differentiation,lymphatic infiltration).Platelets were collected from all subjects,and the levels of autophagy-associated protein 7(ATG7),benzalkonium chloride 1(BECN1),microtubule-associated protein 1 light chain 3(LC3)and sequestosome 1(p62)were measured by enzyme-linked immunosorbent assay(ELISA).Results Among the 360 patients included,peritoneal metastasis was detected in 38 cases.Compared with the non-peritoneal metastasis group,the peritoneal metastasis group exhibited decreased BMI(P<0.05),while the tumor size,non-ulcerative tumor,number of lymph node metastasis,infiltration depth,number of cases of lymphatic invasion,platelet count,platelet LC3-Ⅱ level,platelet ATG7 level and CEA level were increased(P<0.05).Multivariate logistic regression analysis showed that BMI(OR=1.094),lymphatic invasion(OR=2.658),and LC3-Ⅱ(OR=3.793)and ATG7(OR=2.010)were independent influencing factors for peritoneal metastasis in patients with gastric cancer(P<0.05).LC3-Ⅱ>2.59ng/ml had the highest ability to predict peritoneal metastasis in patients with gastric cancer(AUC=0.932),followed by ATG7(AUC=0.916).Conclusions Elevated levels of platelet LC3-Ⅱ and ATG7 are independently related to peritoneal metastasis in patients with gastric cancer,and can be used to predict the occurrence of peritoneal metastasis,which is helpful to guide individualized treatment.

Objective:To investigate the efficacy of the intelligent version of the Montreal Cognitive Assessment Scale(MoCA)in identifying mild cognitive impairment(MCI)in elderly inpatients.Methods:Seventy-five patients diagnosed with mild cognitive impairment(MCI group)from the Neurology and Geriatrics Departments of a tertiary hospital in Changsha City, along with 195 patients with normal cognitive function(normal control group), were selected between July 2020 and December 2022.Both groups underwent evaluations using the intelligent version of the Montreal Cognitive Assessment(MoCA)and the Mini Mental State Examination(MMSE), and the results were analyzed.Results:The MCI group showed significantly lower total MoCA scores and MMSE scores[(19.73±2.42) vs.(24.8±2.33)]compared to the normal control group[(24.47±2.02) vs.(26.50±1.65)], with a statistically significant difference( P<0.01).The optimal cut-off score for the MoCA was found to be 23.5 points in diagnosing MCI, showing higher sensitivity, specificity, and kappa value(96.0%, 82.1%, and 0.690)compared to the MMSE scale(90.0%, 62.6%, and 0.428). Conclusions:The intelligent MoCA has a high screening accuracy for identifying MCI in this population, demonstrating superior sensitivity and specificity compared to the MMSE.

Traditional Chinese medicines (TCMs) possess a rich historical background, unique theoretical framework, remarkable therapeutic efficacy, and abundant resources. However, the modernization and internationalization of TCMs have faced significant obstacles due to their diverse ingredients and unknown mechanisms. To gain deeper insights into the phytochemicals and ensure the quality control of TCMs, there is an urgent need to enhance analytical techniques. Currently, two-dimensional (2D) chromatography, which incorporates two independent separation mechanisms, demonstrates superior separation capabilities compared to the traditional one-dimensional (1D) separation system when analyzing TCMs samples. Over the past decade, new techniques have been continuously developed to gain actionable insights from complex samples. This review presents the recent advancements in the application of multidimensional chromatography for the quality evaluation of TCMs, encompassing 2D-gas chromatography (GC), 2D-liquid chromatography (LC), as well as emerging three-dimensional (3D)-GC, 3D-LC, and their associated data-processing approaches. These studies highlight the promising potential of multidimensional chromatographic separation for future phytochemical analysis. Nevertheless, the increased separation capability has resulted in higher-order data sets and greater demands for data-processing tools. Considering that multidimensional chromatography is still a relatively nascent research field, further hardware enhancements and the implementation of chemometric methods are necessary to foster its robust development.

OBJECTIVES: Acute ischemic stroke (AIS) is one of the main causes of disability in middle-aged and elderly people, and early activity plays an important role in functional recovery. This study aims to understand the factors that affect the implementation of early activity in patients with AIS and to provide reference for promoting early activity implementation and developing intervention strategies for AIS patients. METHODS: Using purposive sampling, 19 AIS patients and their caregivers who visited at Stroke Center in the Third Xiangya Hospital of Central South University and the Third Hospital of Changsha from June to December 2021, as well as 19 medical staff, hospital administrators, or community workers providing medical health services to stroke patients, were selected as interviewes. A semi-structured interview was conducted based on the social ecological theory model, and the Colaizzi seven-step method was used to analyze the interview data. RESULTS: According to qualitative interview results, the factors affecting early activity in AIS patients were summarized into 4 themes and 12 sub-themes: medical staff factors (insufficient knowledge and skills, insufficient knowledge of early activity, unclear division of responsibilities), patient factors (severity of the disease, lack of knowledge, psychological pressure, fear of falling), social environmental factors (lack of social support, shortage of human resources and rehabilitation equipment, insufficient medical insurance support), and evidence and norms (the evidence for early activity needs improvement, lack of standardized early activity procedures). CONCLUSIONS Early activity in AIS patients is impacted by factors at multiple levels, including medical staff, patients, social environment, and evidence and norms. Developing comprehensive intervention strategies to address these factors can promote early activity implementation in AIS patients.

Objective:To explore the correlation between lean nonalcoholic fatty liver disease (NAFLD) and metabolic indicators in a young and middle-aged population undergoing physical examination.Methods:It was a cross-sectional study. A total of 8 250 individuals who underwent routine physical examinations at the Health Medical Center of the Second Affiliated Hospital of Chongqing Medical University from January to December 2021 and met the inclusion and exclusion criteria were selected as the research subbjects. The general examination, fasting blood glucose, blood lipids, liver function, renal function, and fasting color ultrasound examination results were analyzed retrospectively to assess the correlation between lean NAFLD and major metabolic indicators using independent sample t-test, chi-square test, and multivariable logistic regression. Results:The prevalence of lean NAFLD was higher in men than in women (50.7% vs. 49.3%, χ2=97.261, P<0.001). After stratifying the age of onset of lean NAFLD, the peak age of onset was found to be between 45 and 59 years, with the prevalence gradually increasing with age. When stratified by body mass index (BMI), the peak incidence of lean NAFLD was observed in individuals with a BMI of ≥20 and <23 kg/m 2, with the prevalence showing a significant upward trend as BMI increased. The systolic blood pressure, diastolic blood pressure, total cholesterol, triglyceride, low-density lipoprotein, fasting blood glucose, alanine aminotransferase, aspartate aminotransferase, γ-glutamyltransferase, and serum uric acid in lean NAFLD groupwere all significantly higher than those in lean non-NAFLD group (all P<0.01), and the level of high density lipoprotein was significantly lower than that of lean non-NAFLD group ( t=23.755, P<0.001). The logistic analysis showed that systolic blood pressure ( OR=1.258, 95% CI: 1.081-1.465), diastolic blood pressure ( OR=1.282, 95% CI: 1.056-1.557), total cholesterol ( OR=1.712, 95% CI: 1.525-1.923), triglyceride ( OR=4.115, 95% CI: 3.621-4.676), alanine aminotransferase ( OR=1.467, 95% CI: 1.104-1.950), γ-glutamyltransferase ( OR=1.482, 95% CI: 1.242-1.769), fasting blood glucose ( OR=2.479, 95% CI: 2.092-2.939) and serum uric acid ( OR=1.390, 95% CI: 1.236-1.563) were independent metabolic risk factors for lean NAFLD (all P<0.05). Conclusions:The levels of various metabolic markers in young and middle-aged patients with lean NAFLD increase, and the risk of lean NAFLD increases. Metabolic markers are helpful to screen people at risk of lean NAFLD.
