Objective : To investigate the mechanism of puerarin in the treatment of rheumatoid arthritis(RA) by network pharmacology and animal experiments. Methods : Traditional Chinese Medicine Systems Pharmcolog Database(TCMSP) and SwissTargetPrediction database were used to collect puerarin targets, and the targets of RA were obtained from GeneCards database and OMIM database. The PPI network was established by Cytoscape 3.7.2 software. Gene ontology(GO) function and Kyotoencyclopedia of genes(KEGG) enrichment analysis were performed through the Metascape database. RA rat-collagen-induced arthritis(CIA) model was reproduced using type Ⅱ collagen emulsion, 49 Wistar rats were randomly assigned to seven groups: control group, CIA model group, low-dose, medium-dose and high-dose puerarin group, methotrexate group, Tripterysium Glycosides Tablets group. Except for the control group, the other groups were given continuous gavage for 28 days after the CIA in rats model were prepared. The redness and swelling of the joints and ankle joint pathological changes were observed in each group. Western blot was used to detect the expression of Glycogen synthase kinase3β(GSK-3β), beta-catenin(β-catenin) proteins in the synovium. Real-time quantitative polymerase chain reaction(qPCR) was used to detect the expression of GSK-3β, β-catenin and c-Myc mRNA in the synovium. Results : Puerarin had 134 targets genes, RA had 5 821 target genes, and there were 102 overlapping target genes of puerarin and RA. It involved 184 signaling pathways, including JAK-STAT signaling pathway, NF-κB signaling pathway, Wnt signaling pathway, et al. The results of animal experiments showed that after the intervention of M-puerarin and MTX, the symptoms of redness and swelling of the hind foot were alleviated, the inflammatory cell infiltration in the synovium of the joint was significantly reduced, and the damage of cartilage and bone tissue was reduced. Compared with CIA group, the expressions of GSK-3β, β-catenin protein and GSK-3β, β-catenin and c-Myc mRNA in synovial tissue of rats after M-puerarin intervention decreased(P<0.05). Conclusion Puerarin has the characteristic of multi-components, multi-targets and multi-pathway intervention in RA. Puerarin may alleviate synovial hyperplasia, reduce articular cartilage erosion and bone destruction in CIA in rats by inhibiting Wnt/β-catenin signaling pathway.

OBJECTIVE: To investigate the characteristics of Vitamin D (VitD) and bone metabolism in patients with knee osteoarthritis (KOA) concurrent with osteoporosis (OP). METHODS: A retrospective analysis was performed on 240 patients who were admitted to the orthopedics department between March 2019 and March 2024. Patients were stratified into four distinct groups according to their respective disease categories.There were 90 patients in the simple KOA group, comprising 13 males and 77 females, age ranged from 50 to 91 years old with an average of (68.48±8.96) years old. There were 90 patients in the simple OP group, comprising 7 males and 83 females, age ranged from 52 to 88 years old with an average of (69.60±8.94 )years old. There were 30 patients in the KOA with OP group, comprising 1 male and 29 females, age ranged from 51 to 91 years old with an average of(69.03±7.93) years old. There were 30 patients in the physical examination group, comprising 5 males and 25 females, age ranged from 53 to 79 years old with an average of(64.93±6.51) years old. The general data and the levels of osteocalcin (OC), β-CrossLaps, parathyroid hormone(PTH) and VitD in each group were observed. RESULTS: The level of VitD in KOA with OP group (19.62±10.38) ng·ml^-1 and OP group (20.65±10.50) ng·ml^-1 was lower than that in physical examination group (27.46±8.00) ng·ml^-1 and KOA group (24.01±9.11) ng·ml^-1 (P<0.05). There were significant differences in β- CrossLaps and PTH levels among the four groups (P<0.001, P=0.019, respectively), while there was no significant difference in OC levels (P=0.763). Compared with the two simple disease groups, the KOA with OP group had higher levels of β - CrossLaps(0.81±0.30) ng·ml^-1 (P<0.001). There were significant differences in β-CrossLaps and PTH between the simple KOA group(0.54±0.22) ng·ml^-1, (46.03±18.08) pg·ml^-1 and the physical examination group (0.44±0.19) ng·ml^-1, (36.65±9.63) pg·mL^-1(P=0.038;P=0.006). There was a significant difference in PTH between the OP group(43.85±14.30) ng·ml-1, and the physical examination group, P=0.004. There was a significant difference in Kallgren-Lawrence grading between KOA with OP group and KOA group (P=0.006). Within KOA with OP group, the differences of β-CrossLaps and VitD levels among different K-L grades were statistically significant (P=0.016). The level of OC, β-CrossLaps and PTH within KOA with OP group was significantly different at different VitD levels (P=0.013, P=0.033, P=0.046). CONCLUSION Patients with KOA complicated by OP exhibit greater disturbances in bone metabolism and reduced VitD levels, particularly reflected by elevated β-CrossLaps. These findings underscore the importance of early monitoring of bone turnover and VitD supplementation in advanced-stage KOA with bone loss.

Extensive studies have identified potential adverse effects on semen quality of obesity, based on body mass index, but the association between body fat distribution, a more relevant indicator for obesity, and semen quality remains less clear. We conducted a longitudinal study of 4304 sperm donors from the Guangdong Provincial Human Sperm Bank (Guangzhou, China) during 2017-2021. A body composition analyzer was used to measure total and local body fat percentage for each participant. Generalized estimating equations were employed to assess the association between body fat percentage and sperm count, motility, and morphology. We estimated that each 10% increase in total body fat percentage (estimated change [95% confidence interval, 95% CI]) was significantly associated with a 0.18 × 10 6 (0.09 × 10 6 -0.27 × 10 6 ) ml and 12.21 × 10 6 (4.52 × 10 6 -19.91 × 10 6 ) reduction in semen volume and total sperm count, respectively. Categorical analyses and exposure-response curves showed that the association of body fat distribution with semen volume and total sperm count was stronger at higher body fat percentages. In addition, the association still held among normal weight and overweight participants. We observed similar associations for upper limb, trunk, and lower limb body fact distributions. In conclusion, we found that a higher body fat distribution was significantly associated with lower semen quality (especially semen volume) even in men with a normal weight. These findings provide useful clues in exploring body fat as a risk factor for semen quality decline and add to evidence for improving semen quality for those who are expected to conceive.

Objective To understand the current situation of thirst in patients with cirrhosis and analyze its influencing factors,in order to improve medical staff's attention to thirst symptoms in patients with cirrhosis and provide theoretical basis for clinical intervention.Methods A total of 220 patients with cirrhosis who were hospitalized in the infection department of a tertiary A general hospital in Wuhan from March to June 2024 were selected by convenience sampling method.General data questionnaire,Numerical Score Scale and Thirst Distress Scale were used to investigate the factors affecting thirst sensation in patients with cirrhosis.Results A total of 202 valid questionnaires were collected,and the effective questionnaire recovery rate was 91.82％.The results showed that the incidence of thirst in patients with cirrhosis was 59.41％;the score of thirst was 3.00(3.00,6.00)points,and the mean score of thirst was 3.09.Among them,43.07％of the patients with cirrhosis were in the moderate to severe level of thirst.The score of Thirst Distress Scale is 6.00(6.00,17.00)points,and the average score of thirst distress was 11.62 points,which was in the medium level.47.03％of patients with cirrhosis indicated thirst distress,and 23.76％of patients with cirrhosis which was in the moderate and severe level of distress.The results of multiple linear regression analysis showed that the degree of ascites,the use of diuretics,the stage of disease,and the degree of thirst distress were the factors influencing the degree of thirst in patients with cirrhosis(P＜0.05).Gender,marital status,degree of ascites,use of diuretic drugs,disease stage and degree of thirst were the factors influencing degree of thirst distress in patients with cirrhosis(P＜0.05).Conclusion The incidence and severity of thirst in patients with cirrhosis are relatively high,and are affected by many factors.Medical staff should pay more attention to the management of thirst symptoms in patients with cirrhosis,and formulate targeted nursing measures or nursing programs according to the related influencing factors of thirst,so as to improve the comfort level of patients and improve the disease experience of patients.

AIM:To elucidate the intervention and mechanism of 4'-hydroxychalcone(4-HC)in colitis mice through the regulation of Th17/Treg homeostasis.METHODS:Using a dextran sodium sulfate(DSS)-induced colitis model in mice,we meticulously observed the pathological characteristics of colon tissue via HE staining.Additionally,we employed immunohistochemical analysis and Western blot techniques to assess the expression levels of proteins associated with the JAK/STAT signaling pathway,as well as the specific content of tight junction proteins such as ZO-1 and occludin.The differentiation of Th17 and Treg cells was analyzed through flow cytometry.RESULTS:Compared to the normal group,the DSS group exhibited a consistent decline in body weight,coupled with symptoms of diarrhea and hematochezia,an increase in the DAI score,and a notable reduction in colon length.In contrast,the body weight of the 4-HC group dis-played an upward trend following an initial decrease,with improvements in diarrhea and hematochezia symptoms,a reduc-tion in the DAI score,and a restoration of colon length relative to the model group.The integrity of colon tissue in the 4-HC group was significantly better than that in the DSS group,evidenced by a marked increase in the number of goblet cells and an enhancement in crypt integrity,while the average histology score showed a decrease.Western blot analysis re-vealed substantial increase in ZO-1 and occludin expression after 4-HC treatment.Flow cytometry results indicated a dra-matic decrease in the differentiation rate of Th17 cells in spleen lymphocytes and mesenteric lymph nodes,while the dif-ferentiation rate of Treg cells was significantly elevated.Immunohistochemical and Western blot analyses demonstrated that 4-HC markedly reduced the phosphorylation of STAT1 and STAT3,while up-regulating the phosphorylation of STAT6,suggesting that 4-HC modulates CD4+T cell activity through the JAK-STAT pathway.CONCLUSION:The 4-HC may enhance the course of DSS-induced colitis in mice,alleviate colonic tissue damage,and modulate the balance be-tween Th17 and Treg cells,potentially involving the JAK/STAT signaling pathway.

Objective To explore causal relationship between 25-hydroxyvitamin D[25(OH)D]and ankylosing spondylitis(AS).Methods Genetic data of 25(OH)D and AS were extracted from the genome-wide association study.The causal effect of 25(OH)D on AS was estimated by MR-Egger regression method,weighted median,inverse variance weighted(IVW),simple mode and weighted mode,and sensitivity analysis was conducted for verification.Results The IVW results indicated that there was a causal relationship between 25(OH)D concentration and AS(OR=0.805,95％CI:0.686-0.944,P=0.008),and the maximum likelihood ratio(OR=0.799,95％CI:0.678-0.940,P=0.007)showed consistent results.The IVW results of the reverse Mendelian randomization study showed that there was no causal relationship between the two(OR=1.019,95％CI:0.995-1.043,P=0.110).In addition,MR-Egger intercept,Cochran Q test,"leave-one-out"and MR-PRESSO analysis showed no horizontal pleipotency or heterogeneity.Conclusion There may be a genetic causal relationship between the concentration of 25(OH)D and the onset of AS.AS cannot cause changes in the concentration of 25(OH)D in the body.

Objective:To evaluate the effectiveness of remote management based on unmet health needs self-monitoring reports in patients with colorectal cancer.Methods:A total of 124 colorectal cancer inpatients admitted to the First Affiliated Hospital of Zhengzhou University from October 2022 to September 2023 were selected using convenience sampling and randomly divided into a control group and an intervention group (62 patients each). The control group received routine follow-up care, while the intervention group received remote management based on self-monitoring reports of unmet health needs in addition to routine follow-up, over a 3-month period. To evaluate the outcomes, the Health Literacy Management Scale (HeLMS), the Health Promoting Lifestyle Profile-II (HPLP-II), the Short Form of the Unmet Needs Survey (SF-SUNS), and the Self-Care Self-Efficacy Scale (SCSES) were compared between two groups.Results:After the intervention, the intervention group showed significantly higher scores in HeLMS, HPLP-II, and SCSES compared to their baseline values and the control group ( P<0.05). Additionally, the SF-SUNS score was significantly lower in the intervention group post-intervention than both its baseline and the control group post-intervention ( P<0.05) . Conclusions:Remote management based on unmet health needs self-monitoring reports effectively improves health literacy, promotes healthier lifestyles, enhances self-management efficacy, and reduces levels of unmet health needs in patients with colorectal cancer.
