ObjectiveTo explore the mechanism of Yishen Qubi Tongluo Formula （益肾祛痹通络方， YQTF） in the treatment of rheumatoid arthritis（RA）. MethodsNetwork pharmacology was employed to retrieve and screen the active components and potential targets of YQTF as well as RA-related targets using databases including TCMSP， BATMAN， ETCM and GEO. The intersection of targets related to active components and RA-related targets was identified， and a protein-protein interaction （PPI） network was constructed. Gene Ontology （GO） functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis were performed， and a drug-active component-common target network of YQTF in the treatment of RA was established. The core components of YQTF were molecularly docked with key targets. Human rheumatoid arthritis synovial fibroblast cell line MH7A was divided into blank group， model group， methotrexate group and YQTF group. The blank group was cultured with 10% fetal bovine serum， while the other three groups were stimulated with 10 μg/L of recombinant human tumor necrosis factor-α （TNF-α） for 24 h to establish the RA cell model. On this basis， the methotrexate group was treated with methotrexate suspension at a concentration of 20 μmol/L， and the YQTF group was treated with 10% YQTF-medicated serum. After 48 h of intervention， the levels of TNF-α and interleukin-17A（IL-17A）contents in cell supernatants were detected by enzyme-linked immunosorbent assay （ELISA）， and mRNA expressions of phosphatidylinositol 3-kinase（PI3K）， protein kinase B（AKT） and mammalian target of rapamycin（mTOR） were detected by real-time quantitative polymerase chain reaction （RT-qPCR）. ResultsNetwork pharmacological analysis identified 209 active components and 583 potential target genes of YQTF， as well as 818 RA-related targets. A total of 29 common targets were obtained from the intersection of drug-related targets and RA-related targets. Quercetin，β-sitosterol， kaempferol， stigmasterol and luteolin were the core active components of YQTF for the treatment of RA， while matrix metalloproteinase-9 （MMP9）， prostaglandin-endoperoxide synthase 2 （PTGS2）， Toll-like receptor 4 （TLR4）， tumor protein p53 （TP53） and transcription factor AP-1 subunit JUN were the key targets. The GO and KEGG pathway enrichment analysis showed that the involved biological processes and pathways were mainly associated with antioxidant responses， PI3K-AKT signaling pathway and Toll-like receptor （TLR） signaling pathway. Molecular docking results showed that MMP9 and PTGS2 exhibited high binding affinities with quercetin， β-sitosterol， kaempferol， stigmasterol and luteolin； TLR4 exhibited high binding activities with β-sitosterol， stigmasterol and luteolin； and TP53 showed high binding affinity with luteolin. The results of cell experiments showed that compared with the control group， the contents of TNF-α and IL-17A as well as the mRNA expressions of AKT and mTOR in the model group significantly increased （P＜0.05 or P＜0.01）. Compared with the model group， all the above indicators significantly decreased in the YQTF group， while the contents of TNF-α and the mRNA expression of AKT significantly decreased in the methotrexate group （P＜0.05 or P＜0.01）. ConclusionThe mechanism of YQTF in the treatment of RA may be associated with reducing inflammatory cytokine secretion and inhibiting the activation of the PI3K-AKT-mTOR signaling pathway.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Objective To explore the effects of different nerve blocks under ultrasound guidance on the expression of inflammatory factors after total hip replacement in the elderly,and its correlation with postoperative cognitive dysfunction(POCD).Methods A total of 100 elderly patients who underwent total hip replacement in our hospital from February to November 2023 were selected as the research objects,and they were divided into the femoral nerve block(FNB)group and the pericapsule nerve group block(PNGB)group according to different nerve block methods during the operation.The expression of inflammatory factors such as serum interleukin-1β(IL-1β),interleukin-6(IL-6),interleukin-10(IL-10),tumor necrosis factor-α(TNF-α)and tumor necrosis factor-β(TNF-β)1 day before surgery,6 hours after anesthesia,1 day after surgery,and 3 days after surgery of patients in the two groups were compared.The cognitive function of patients was evaluated by the mini-mental state examination(MMSE)score,and the pain of patients was evaluated by visual analogue scale(VAS)score.GEE model was used to evaluate the effects of two kinds of nerve block on the expression of inflammatory factors.Logistic regression was used to analyzed the correlation between postoperative inflammatory factors and POCD in patients.Results The levels of IL-1β,IL-6,IL-10,TNF-α and TNF-β 1 day after operation in the PNGB group were higher than those in the FNB group,and the differences were statistically significant(P<0.05).The MMSE score 1 day after surgery in the PNGB group was significantly higher than that in the FNB group(P<0.05),and the VAS score 3 days after surgery was significantly lower than that in the FNB group(P<0.05).GEE model showed that PNGB has a greater impact on IL-1β,IL-6,IL-10,TNF-α,and TNF-β.IL-1β,IL-6,IL-10,TNF-α,and TNF-β were all independently related to POCD induced by two different nerve blocks(P<0.05).Conclusion PNGB can effectively inhibit pro-inflammatory factors,reduce inflammatory stress responses,and maintain the balance of inflammatory factors.Inflammatory factors are independently related to POCD induced by different nerve blocks.With the occurrence of inflammatory stress response,the risk of POCD in patients increases.

Objective This study aimed to investigate the potential relationship between urinary metals copper (Cu), arsenic (As), strontium (Sr), barium (Ba), iron (Fe), lead (Pb) and manganese (Mn) and grip strength. Methods We used linear regression models, quantile g-computation and Bayesian kernel machine regression (BKMR) to assess the relationship between metals and grip strength.Results In the multimetal linear regression, Cu (β=-2.119), As (β=-1.318), Sr (β=-2.480), Ba (β=0.781), Fe (β= 1.130) and Mn (β=-0.404) were significantly correlated with grip strength (P < 0.05). The results of the quantile g-computation showed that the risk of occurrence of grip strength reduction was -1.007 (95％ confidence interval:-1.362, -0.652; P < 0.001) when each quartile of the mixture of the seven metals was increased. Bayesian kernel function regression model analysis showed that mixtures of the seven metals had a negative overall effect on grip strength, with Cu, As and Sr being negatively associated with grip strength levels. In the total population, potential interactions were observed between As and Mn and between Cu and Mn (Pinteractions of 0.003 and 0.018, respectively).Conclusion In summary, this study suggests that combined exposure to metal mixtures is negatively associated with grip strength. Cu, Sr and As were negatively correlated with grip strength levels, and there were potential interactions between As and Mn and between Cu and Mn.

Most information used to evaluate diabetic statuses is collected at a special time-point, such as taking fasting plasma glucose test and providing a limited view of individual's health and disease risk. As a new parameter for continuously evaluating personal clinical statuses, the newly developed technique "continuous glucose monitoring" (CGM) can characterize glucose dynamics. By calculating the complexity of glucose time series index (CGI) with refined composite multi-scale entropy analysis of the CGM data, the study showed for the first time that the complexity of glucose time series in subjects decreased gradually from normal glucose tolerance to impaired glucose regulation and then to type 2 diabetes (P for trend < 0.01). Furthermore, CGI was significantly associated with various parameters such as insulin sensitivity/secretion (all P < 0.01), and multiple linear stepwise regression showed that the disposition index, which reflects β-cell function after adjusting for insulin sensitivity, was the only independent factor correlated with CGI (P < 0.01). Our findings indicate that the CGI derived from the CGM data may serve as a novel marker to evaluate glucose homeostasis.

In the outbreak of COVID-19,triage procedures based on epidemiology were implemented in a local hospital in Changsha to control the transmission of SARS-CoV-2 and avoid healthcare-associated infection.This re-trospective study analyzed the data collected during the triage period and found that COVID-19 patients were en-riched 7 folds into the Section A designated for patients with obvious epidemiological history.On the other side,nearly triple amounts of visits were received at the Section B for patients without obvious epidemiological history.8 COVID-19 cases were spotted out of 247 suspected patients.More than 50％of the suspected patients were submi-tted to multiple rounds of nucleic acid analysis for SARS-CoV-2 infection.Of the 239 patients who were diagnosed as negative of the virus infection,188 were successfully revisited and none was reported as COVID-19 case.Of the 8 COVID-19 patients,3 were confirmed only after multiple rounds of nucleic acid analysis.Besides comorbidities,delayed sharing of epidemiological history added complexity to the diagnosis in practice.The triaging experience and strategy will be helpful for the control of infectious diseases in the future.

Objective:To evaluate the clinical efficacy and safety of Longmu Zhuanggu granule for the treatment of children recurrent respiratory infection due to lung-spleen Qi deficiency. Method:This multicenter stratified， block-randomized， double-blind， double-dummy， positive drug （pidotimod granule） parallel controlled， and non-inferiority trail intended to included 240 children patients and divided them into the experimental group （n=120） and the control group （n=120） at the ratio of 1∶1. Patients in both groups were treated for eight successive weeks and followed up for 12 months. The cure rates， numbers of respiratory infections， average courses of disease， curative effects of traditional Chinese medicine （TCM） syndrome， curative effects of individual symptoms， curative effects of immune indexes， and safety indexes between the two groups were observed and compared. Result:A total of 237 subjects were collected from 10 research centers， including 119 cases in the control group and 118 in the experimental group. There were 236 cases enrolled into the full analysis set （FAS）， 210 into the per-protocol set （PPS）， and 236 into the safety set （SS）. The baseline data of the two groups were not significantly different from each other， indicating that they were comparable. The cure rates of the experimental group and control group were 75.21% （88/117） and 73.95%（88/119）， respectively， with the 95% confidence interval （CI） of difference between the two groups being 1.26% （-9.85%，12.37%） for FAS and 3.81% （-6.28%，13.90%） for PPS. The 95% CI fell within the 10% non-inferiority margin， implying that non-infertility test of the cure rate in the treatment of endpoint disease was valid， and the conclusions of FAS and PPS analysis were consistent. There was no significant difference in the number or course of upper respiratory infection， bronchitis， and pneumonia. The difference in curative effects of TCM syndrome between the two groups after four weeks of treatment was not remarkable. After eight weeks of treatment， the total effective rate of the experimental group was 84.62%（99/117）， statistically higher than 78.15%（93/119） of the control group（χ²=-3.26，P<0.05）. There were no significant differences in the disappearance rates of individual symptoms between the two groups after four weeks of treatment. After eight weeks of treatment， the experimental group and control group exhibited the disappearance rates of 67.50%（54/80） and 47.37%（36/76） for shortness of breath and laziness to speak， 75.00%（54/72） and 53.33%（40/75） for poor appetite， 54.55%（60/110） and 37.84%（42/111） for hyperhidrosis， respectively， with obviously better outcomes observed in the experimental group （P<0.05，P<0.01）. The inter-group comparison revealed significant differences in immune indexes after eight weeks of treatment. As demonstrated by comparison with the situations before treatment， IgA， IgG， IgM， and CD4 did not change significantly after treatment. Except for CD8 in the experimental group (P<0.05), there was no significant difference in other immune indexes before and after treatment There was no significant difference in the incidence of adverse reactions. Conclusion:Longmu Zhuanggu granule is not inferior to pidomod granule in the treatment of children recurrent respiratory infection due to lung-spleen Qi deficiency， and it exhibits good safety， implying its promising clinical application value.

OBJECTIVETo investigate the influence of thrombelastography index changes on its sensitivity and specificity for diagnosis of disseminated intravascular coagulation (DIC) in children.

METHODSA total of 149 children with DIC in our hospital from June 2013 to June 2016 were selected in DIC group, while 106 cases of non-DIC, including healthy children and children with diseases easily confused with DIC, were selected as non-DIC(control) group. The thrombelastography, D-dimer, coagulation functions including prothrombintime (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB) and fibin degradation product (FDP), congental coagulation disorders and platelet count were detected in DIC and non-DIC groups; the statistics of data was performed and the sensitivity and specificity of thromelastraphy indexes such as R time, α angle MA value and A value were evaluated; the relationship of DIC with indexes was analyzed. Moreover, the result difference of thromelastography and routine coagulation function test was compared at diagnosis of DIC.

RESULTSAccording to statistical analysis of clinical data in 2 groups, the average R time in non-DIC group was significantly less than that in DIC group (P<0.05); the average α angle in non-DIC group was larger than that in DIC group (P<0.05), both the MA and A values in the non-DIC group were significantly higher than those in DIC group (P<0.05). The specificity of routine coagulation function test for diagnosis of DIC was as follow: PT-27.2%, APTT-42.2%, international normalized ratio(INR)-47.9%, FIB-44.4%, FDP-42.7% and D-dimer-68.3%, which were significantly lower than that of R time,α angle and MA value for diagnosis of DIC (85.1%, 74.1% and 73%). The α angle and MA value of healthy children were greater than those of children with severe liver disease(P<0.05). while the average R time of healthy children was less than that of children with severe liver disease(P<0.05), but the difference of A value between them did not statistically significant (P>0.05) . The average R time of healthy children was less than that of children with congenital coagulation disorders (P<0.05). but there was no significant differences in α angle MA and Avalues between them.

CONCLUSIONAs compared with routine coagulation function test, the thrombelastography shows more high specificity for diagnosis of DIC, and can more precisely diagnose the DIC; moreover, the thrombelastography combined with roatime coagulation function test can more early find and diagnose the DIC in children, therefore it can improve the survival rate of children with DIC.
