Objective:To clarify the effect of methotrexate on blood uric acid levels and the incidence of hyperuricemia in patients with rheumatic and musculoskeletal diseases (RMDs).Methods:The clinical data were collected from 349 patients with RMDs who took methotrexate for more than 52 weeks and 429 patients with RMDs who did not take methotrexate, who were treated at Anqing Medical Center of Auhui Medical University from June 1, 2022 to June 30, 2024, to compare the differences in serum uric acid concentration and the incidence of hyperuricemia before and after 24 weeks of methotrexate administration in the two groups of patients with RMDs. The changes in serum uric acid concentration and serum creatinine value in the MTX na?ve patients who had taking MTX for 0, 24 and 52 weeks were compared. The relationship between serum uric acid concentration and methotrexate dosage was analyzed. Measurement data were compared using t-test or ANOVA, repeated measures analysis of variance, and count data were compared using χ2 test. Results:①At week 0, there was no significant difference in serum uric acid concentration [(300±63)μmol/L vs. (306±64)μmol/L, t=-1.416, P=0.157] and the incidence of hyperuricemia [9.3%(40/429) vs. 10.3%(36/349) , χ2=0.215, P=0.643] between the two groups. At week24, the serum uric acid concentration (307±70)μmol/L vs. (246±89)μmol/L was statistically significantly ( t=10.909, P<0.001) different. The incidence of hyperuricemia (11.0%, 47/429) vs. (4.6%, 16/349), was statistically significantly different ( χ2=10.497, P<0.001). There was a statistically significant difference in serum uric acid concentration between week 0 and week 24 in the methotrexate group ( t=10.237, P<0.001), and there was a statistically significant difference in the incidence of hyperuricemia ( χ2=8.312, P=0.004). ②The overall serum uric acid concentrations at week 0, weeks 24, and weeks 52 were (306±64)μmol/L, (246±89)μmol/L, and (247±66)μmol/L, respectively. The difference in overall serum uric acid concentration was statistically significant ( F= 29.506, P<0.001). There was no significant difference in serum uric acid concentration between weeks 24 and 52 ( P=1.000). There were significant differences in serum creatinine levels between weeks 0, 24 and 52 ( P<0.001). There was no significant difference in serum creatinine levels between weeks 0 ,52, weeks 24 and 52 ( P=0.077, P=1.000). There were statistically significant differences in the overall serum uric acid concentration and serum creatinine value at weeks 0, 24 and 52 of medication ( P<0.001).③ There was no significant difference in serum uric acid concentration before and after taking hydroxychloroquine, cyclosporine, tripterygium wilfordii, mycophenolate mofetil, tofacitinib, etanercept and adalimumab alone for weeks 0 and 24(all P>0.05). ④There was no significant difference in serum uric acid concentration between patients taking different doses of methotrexate (7.5 mg once weekly, 10 mg once weekly, 12.5 mg once weekly, 15 mg once weekly) at weeks 0 and 24 weeks(all P>0.05). Conclusion:MTX, as an anti-rheumatic drug, reduces the serum uric acid level and the incidence of hyperuricemia in patients with RMDs during the treatment.

Breast cancer is one of the most common tumors worldwide.Despite significant pro-gress in diagnosis and treatment,the incidence and mortality rates remain high due to its highly inva-sive and metastatic characteristics.Trichorhinophalangeal syndrome type 1(TRPS1)is an atypical globin transcription factor-1(GATA).It plays an important role in regulating cell proliferation and differentiation and tissue growth.Studies have found that TRPS1 is significantly overexpressed in breast cancer and closely related to tumor invasion and metastasis.TRPS1 is specifically expressed in the ductal epithelial cells of breast tissue and closely associated with the differentiation of breast ducts.In recent years,scholars have mainly focused on the role and mechanisms of TRPS1 in the di-agnosis and treatment of breast cancer.This review summarized the research progress of TRPS1 in breast cancer,aiming to further analyze its clinical application value in the occurrence,development,diagnosis,and treatment of breast cancer.

Objective To explore the effects of sodium oligomannate combined with high-frequency repetitive transcranial magnetic stimulation on the activity of daily living and intelligence level of patients with Alzheimer's disease.Methods A total of 100 patients with Alzheimer's disease admitted to Henan Provincial Staff Hospital from September 2021 to September 2023 were selected as the research subjects.These patients were divided into an observation group and a control group according to the random number table method,with 50 patients in each group.Patients in the control group were given high-frequency repetitive transcranial magnetic stimulation,and patients in the observation group were given sodium oligomannate combined with high-fre-quency repetitive transcranial magnetic stimulation.Enzyme-linked immunosorbent assay was used to detect the levels of amyloid β-protein(Aβ)142,tumor necrosis factor-a(TNF-a)and interleukin-6(IL-6)in patients of the two groups before and after treatment.Chemiluminescence was used to detect the levels of neurotransmitters in patients of the two groups before and after treatment.The mental symptoms of patients in the two groups before and after treatment were evaluated by the behavioral pathology in Alzheimer's disease rating scale,the intelligence level of patients in the two groups before and after treatment was evaluated by the mini-mental state examination(MMSE)scale and the Montreal cognitive assessment(MoCA)scale,the activity of daily living of patients in the two groups before and after treatment was evaluated by Alzheimer's disease cooperative study-activity of daily living(ADCS-ADL),and the quality of life of patients in the two groups before and after treatment was evaluated by the quality of life-Alzheimer's disease scale.Results Before treatment,the two groups showed no significant difference in the levels of Aβ1-42,TNF-α and IL-6(P＞0.05);after treatment,the levels of Aβ1-42,TNF-α and IL-6 in both groups were lower than those before treatment,and the levels of Aβ1-42,TNF-α and IL-6 in the observation group were lower than those in the control group(P＜0.05).Before treatment,there were no statistically significant differences in the levels of 5-hydroxytryptamine(5-HT),acetylcholine(ACh),γ-aminobutyric acid(GABA),and Alzheimer-associated neuronal thread protein(AD7c-NTP)between the two groups(P＞0.05);after treatment,the levels of 5-HT,ACh,and GABA in the two groups were higher than those before treatment,while the AD7c-NTP level was lower than that before treatment(P＜0.05);after treatment,the levels of 5-HT,ACh,and GABA in the observation group were higher than those in the control group,while the AD7c-NTP level was lower than that in the control group(P＜0.05).Before treatment,there were no significant differe-nces in the scores of paranoid and delusional ideas,hallucinations,behavioral disorders,aggressive behaviors,daily rhythm disorders,emotional disorders,anxiety and fear,and the total scores between the two groups(P＞0.05);after treatment,the scores of paranoid and delusional ideas,hallucinations,behavioral disorders,aggressive behaviors,daily rhythm disorders,emotional disorders,anxiety and fear,and the total scores of patients in the two groups were lower than those before treatment,and the scores of paranoid and delusional ideas,hallucinations,behavioral disorders,aggressive behaviors,daily rhythm disorders,emotional disorders,anxiety and fear,and the total scores of patients in the observation group were lower than those in the control group(P＜0.05).Before treatment,there were no significant differences in MMSE,MoCA and ADCS-ADL scores of patients between the two groups(P＞0.05);after treatment,the MMSE,MoCA and ADCS-ADL scores of patientsin the two groups were higher than those before treatment,and the MMSE,MoCA and ADCS-ADL scores of patientsin the observation group were higher than those in the control group(P＜0.05).Before treatment,there were no significant differences in the scores of physiological function,mental function,behavioral ability and interpersonal relationship,and the total scores of patients between the two groups(P＞0.05).After treatment,the scores of physiological function,mental function,behavioral ability and interpersonal relationship,and the total scores of patients in the two groups were higher than those before treatment,and the scores of physiological function,mental function,behavioral ability and interpersonal relationship,and the total scores of patients in the observation group were higher than those in the control group(P＜0.05).Conclusion Sodium oligomannate combined with high-frequency repetitive transcranial magnetic stimulation can improve the inflammatory state of patients with Alzheimer's disease,regulate neurotransmitter levels,alleviate psychiatric symptoms,enhance the intelligence level and the activity of daily living,and increase the quality of life.

Objective To investigate the effects of total flavonoids from Vine tea on the intestinal flora of high-fat diet(HFD)induced non-alcoholic fatty liver disease(NAFLD)mice.Methods Twenty-eight mice were randomly divided into four groups:blank control group,model control group(HFD group),low-dose TF group(TF-L group),and high-dose TF group(TF-H group),with 7 mice in each group.Mice in the HFD group,TF-L group,and TF-H group were fed with high-fat diet(HFD)for 12 weeks,while those in the blank control group were fed a normal diet.After 12 weeks of high-fat diet feeding,mice in the TF-L group and TF-H group were orally administered TF solution at doses of 125 and 250 mg·kg-1·d-1 by gavage administration for 6 weeks of intervention.Pathological changes in the liver and intestine of mice were observed using hematoxylin-eosin(H&E)staining,and the expression levels of tight junction proteins between the epithelial cells of the colonic mucosa was analyzed by immunohistochemistry.ELISA kit was used to detect the level of serum inflammatory factors in mice.Changes of intestinal flora in mice were analyzed by 16S rRNA sequencing technology.Results Total flavonoids from Vine tea could effectively improve the pathological changes of liver and intestinal tract in mice,reduce the levels of serum inflammatory factors IL-6 and TNF-α,and promote the expression of tight junction proteins Occludin,ZO-1 and Claudin 1 in the colon.There were significant differences in the intestinal flora of the three groups of mice.Total flavonoids from Vine tea significantly decreased the ratio of Firmicutes to Bacteroidota(P＜0.05),increased the abundance of Faecalibaculum,Ligilactobacillus and Lactobacillus,which resulted in the improvement of intestinal flora disorders.Conclusion Total flavonoids from Vine tea have certain ameliorative effects on high-fat diet-induced NAFLD,and the mechanism may be related to the promotion of intestinal barrier repair and the improvement of intestinal flora disorders.

Objective:To analyse the clinical significance of selective single embryo transfer by time-lapse mo-nitoring(TLM)or conventional morphology assessment(CMA)in vitro fertilization/intracytoplasmic sperm in-jection and embryo transfer(IVF/ICSI-ET),and to initially explore the predictive value of Raman spectral analy-sis of embryo culture medium for clinical pregnancy rate.Methods:The study is a prospective randomized con-trolled clinical trial.We assigned 139 patients treated with IVF/ICSI-ET in Reproductive and Genetics Center of Suzhou Municipal Hospital from April 2019 to July 2020,which were randomly assigned to either the CMA or the TLM group.We performed selective single-embryo transfer(fresh cycle and FET)after selecting the optimal em-bryos with TLM or CMA respectively.If the patient's first embryo transfer was unsuccessful,a second one would be performed to compare the differences in the cumulative live birth rate of embryo transfer and other pregnancy outcomes between the two groups.Meanwhile,we collected 15 μl of embryo culture medium at day 3 after IVF/ISCI fertilization for Raman spectroscopy analysis.Results:There were no differences in cumulative live birth,cu-mulative clinical pregnancy,cumulative premature birth,cumulative early spontaneous abortion,cumulative ectopic pregnancy and LGA or SGA between TLM and CMA groups(P＞0.05).The Neonatal sex ratio in the TLM group was lower than that in the CMA group,but the difference was not significant(P＞0.05).Raman spectros-copy analysis of embryo culture medium predicted the clinical pregnancy rate with 67.21％accuracy.Conclu-sions:In young women with a good ovarian reserve,the advantage of using TLM to evaluate embryos is not obvi-ous,so we should remain vigilant that embryo selection based on morphokinetic parameters may affect the sex ratio.Raman spectroscopic analysis of embryo culture medium is not yet able to effectively predict the planting ability of embryos.

BACKGROUND:Ginseng extracts have been found to significantly improve osteoarthritis,but the therapeutic effects of ginseng polysaccharide extracts on osteoarthritis have not been reported. OBJECTIVE:To investigate the effect of ginseng polysaccharide on the expression of prostaglandin E2/6-keto-prostaglandin F1α in traumatic osteoarthritis model rats. METHODS:Sixty male Sprague-Dawley rats were selected and randomly divided into healthy group,model group,ginseng polysaccharide low-dose group,ginseng polysaccharide medium-dose group,ginseng polysaccharide high-dose group and dexamethasone group.Except for 10 rats in the healthy group,the other rats were taken to establish traumatic osteoarthritis models.The healthy group and model group were given 0.2 mL of normal saline intraperitoneally.The low-,medium-,and high-dose groups were intraperitoneally injected with 0.1,0.25,0.5 μg/mL ginseng polysaccharide,respectively.In the dexamethasone group,0.2mg/kg dexamethasone(0.2 mL)was injected intraperitoneally.Injections were given once every 3 days,for 4 consecutive weeks.Serum prostaglandin E2 and 6-keto-prostaglandin F1α levels were detected by ELISA.The bone and joint function of rats were assessed by the Mankin's score.Hematoxylin-eosin staining was used to observe the pathologic morphology of the knee joints of rats.Western blot and PCR were used to detect the protein and mRNA expression of tumor necrosis factor α and interleukin-1β,interleukin-10 in articular cartilage tissue,respectively. RESULTS AND CONCLUSION:Compared with the model group,serum prostaglandin E2 levels were decreased in the medium-dose group and dexamethasone group,while serum 6-keto-prostaglandin F1α levels were increased(P<0.05).Compared with the medium-dose group and dexamethasone group,the above-mentioned indicators were significantly improved in the high-dose group,and there was no significant difference between the medium-dose group and dexamethasone group(P>0.05).Compared with the model group,the Mankin's score was reduced in the medium-dose group and dexamethasone group(P<0.05),but there was no significant difference between the medium-dose group and dexamethasone group(P>0.05).Compared with the medium-dose group and dexamethasone group,the Mankin's score was significantly reduced in the high-dose group(P<0.05).The cartilage tissue layer of rats in the model and low-dose groups was significantly thinned,the cracks and chondrocytes deep into the bone layer were largely lost,the tide line was seriously broken and blurred,the collagen fibers in the synovial layer were increased and thickened,and a large number of chondrocytes were destroyed and arranged irregularly.These pathological changes were improved in the medium-dose group and dexamethasone group compared with the model group as well as improved in the high-dose group compared with the medium-dose group.Compared with the model group,the expression of tumor necrosis factor-α and interleukin-1β was reduced,while the expression of interleukin-10 was increased in the medium-dose group and dexamethasone group(P<0.05).These indicators in the joint were significantly improved in the high-dose group compared with the medium-dose group and dexamethasone group(P<0.05),but there was no significant difference between the medium-dose group and dexamethasone group(P>0.05).To conclude,ginseng polysaccharide can improve the inflammatory level and pathological morphology of traumatic osteoarthritis rats and reduce the Mankin's score.Its mechanism may be related to the regulation of prostaglandin E2/6-keto-prostaglandin F1α levels.

Flos Trollii is a traditional Chinese medicinal herb in China. The 2020 edition of the Chinese Pharmacopoeia （part 1） did not include the medicinal herb， its source is not clear， and there is a lack of relevantly systematic and comprehensive research. By consulting ancient Chinese herbal medicines， medical books and related literature， the textual research of Flos Trollii was conducted to verify the name， origin and producing area， so as to provide a reference for the clinical application and resource development of Flos Trollii. Through textual research， it could be seen that the name “Jinlianhua” was used as the correct name in the mainstream origin of the past dynasties， and there were still multiple synonyms such as Hanjinlian， Jinmeicao and so on， most of which originated from its growth environment and appearance. According to the distribution of varieties， it could be inferred that the mainstream origin of Flos Trollii in the Qing Dynasty and before was Trollius chinensis Bge. According to historical records， Flos Trollii were mostly produced in northern regions such as Hebei， Inner Mongolia， Shanxi， etc.， which was related to the fact that Flos Trollii liked cloudy， humid and cold environments. Based on the textual research results， the author suggested that the mainstream origin of the past dynasties T. chinensis Bge. should be selected for subsequent collection of Flos Trollii.
