It is proposed that the pathogenesis of rheumatoid arthritis （RA） is centered on deficiency， dampness， and blood stasis， which interact with and evolve into one another during the onset and progression of the disease. The development of RA is closely associated with insufficiency of healthy qi and the interbinding of dampness and blood stasis. Accordingly， treatment emphasizes an integrated approach that combines tonifying deficiency， eliminating dampness， and resolving blood stasis， and is implemented in three main stages. In the initial stage， therapy focuses on supporting healthy qi， dispelling dampness， and relieving impediment， with modified Huangqi Guizhi Wuwu Decoction （黄芪桂枝五物汤） combined with Yiyiren Decoction （薏苡仁汤）. In the active stage， treatment aims to eliminate dampness， resolve blood stasis， and unblock the collaterals， using modified Wutou Decoction （乌头汤） or Guizhi Shaoyao Zhimu Decoction （桂枝芍药知母汤）. In the remission stage， therapy emphasizes strengthening the spleen and reple-nishing qi to prevent recurrence， with modified Shenling Baizhu Powder （参苓白术散） combined with Guipi Decoction （归脾汤）.

ObjectiveTo investigate the effect of Toxoplasma gondii infection on copper metabolism in the kidneys of mice. MethodsA total of 80 7-8-week-old C57BL/6 female mice were randomly divided into four groups of 20 mice in each group after one week of adaptation， including Control group， Cu group， TgCtwh6 group and Cu+TgCtwh6 group. Mice that were not infected and fed with normal diet and water were used as the Control group； Mice fed with 1 g/kg of copper chloride processing diet and 0.1% copper chloride water for 60 consecutive days were used as Cu group； Mice infected with 25-30 TgCtwh6 cysts （one of the predominant genotype Chinese 1 in China） fed with normal diet and water were used as the TgCtwh6 group； mice infected with 25-30 TgCtwh6 cysts and fed with a processed diet containing 1 g/kg of copper chloride and water with 0.1% copper chloride for 60 consecutive days were used as the Cu+TgCtwh6 group. ICP-MS was used to determine the changes in copper content in kidney tissues. Hematoxylin-eosin （HE） staining was used to observe the pathological changes of mouse kidney tissue. The number of apoptotic cells was observed by PI staining. Western blot was used to detect the protein expression levels of glutathione peroxidase 4 （GPX4） and superoxide dismutase （SOD1， SOD2）. RT-qPCR was used to detect the mRNA expression of cuproptosis-related genes. ResultsPathological manifestations such as inflammatory cell infiltration in the Cu group and TgCtwh6 group were seen under the microscope， and the inflammatory infiltrating cells of the renal interstitial were reduced in the Cu+TgCtwh6 group， and the pathological manifestations

Objective: To investigate the impact of extracurricular physical activity on heart rate variability (HRV) among primary and secondary school students in Chengdu City, so ao to provide references for scientific exercise prescription. Methods: Using a convenient sampling method, 1 323 primary and secondary students were enrolled from central Chengdu who underwent physical fitness assessments at Sichuan Provincial Institute of Sports Science from September 2020 to January 2022. According to the standards of the National Physical Fitness Monitoring Center, boys and girls were divided into groups with and without extracurricular physical exercise habits. HRV was monitored using the SA-3000P device. Key HRV parameters were evaluated separately by gender, including standard deviation of normal to normal intervals (SDNN), root mean square of successive differences (rMSSD), total power (TP), low frequency power (LF) and high frequency power (HF). Statistical analyses were employed by t-test, Mann-Whitney U-test and Chi square test. Results: lgSDNN, lgrMSSD, TP, LF and HF in the group without extracurricular physical exercise habit [boys:(1.67±0.13)ms, (1.59±0.20)ms, (7.34±0.73)ms 2, (6.11±0.74)ms 2, (6.05±0.87)ms 2; girls:(1.67± 0.13)ms , (1.59±0.19)ms, (7.35±0.60)ms 2, (6.06±0.69)ms 2, (6.12±0.87)ms 2] were lower than those in the group with extracurricular physical exercise habit [boys:(1.75±0.13)ms, (1.72±0.18)ms, (7.69±0.62)ms 2, (6.41±0.76)ms 2, (6.44±0.79)ms 2；girls:(1.73±0.13)ms, (1.68±0.20)ms, (7.60±0.65)ms 2, (6.26±0.86)ms 2, (6.36±0.90)ms 2] ( t =-8.24, -8.75, -6.54, -5.35 , -6.33；-5.10，-4.90，-4.47，-2.71，-2.93, all P ＜0.01). Only the group of boys without extracurricular physical exercise habits showed a decrease in lgLF/HF [0.04(-0.19,0.27)] compared to the group with extracurricular physical exercise habits [ -0.03 (-0.25,0.20)] ( Z=-2.01, P <0.05). When the score classes of autonomic nerve activity, stress index and fatigue index were compared between boys and girls groups without and with extracurricular physical exercise habits, the proportion of boys normal and above scores increased from 79.3%, 84.1%, 71.8% to 91.4%, 95.7%, 87.3%, respectively, and the differences were statistically significant ( χ 2=47.42, 63.66, 38.28); the proportion of girls normal score and above increased from 79.8%, 85.7%, 75.0% to 85.4%, 92.1%, 79.4%, and the differences were statistically significant ( χ 2=48.31, 22.18, 22.22) (all P <0.01). Conclusion The primary and secondary school students who have the habit of extracurricular physical exercise have enhanced compliance in indicators related to HRV, showing more complex heart rate variability.

Background The high work intensity and possible subsequently increased susceptibility to occupational hazards of calcium carbide plants may lead to hypertension in workers, but there are few studies on the relationship between occupational hazard exposure and hypertension in workers involving the production process of calcium carbide. Objective To explore the influence of occupational hazards on the incidence of hypertension in calcium carbide plants. Methods Using historical cohort design, the employees of a calcium carbide factory in the western part of Inner Mongolia Autonomous Region were selected as research subjects. According to the pre-determined inclusion and exclusion criteria, the study population comprised an exposure group of 377 employees (including furnace workers, inspection workers, and maintenance workers) exposed to dust, noise & carbon monoxide, and a control group of 388 employees (including central control workers, electricians, and administrative personnel) without above-mentioned exposure. The total sample size was 765 participants. The follow-up period was from April 2011 to October 2022, and the study endpoint was defined as the conclusion of the follow-up period or diagnosed hypertension in annual occupational health examination. Information on general demographic characteristics, living habits, and work status was collected from all study subjects. Cox proportional hazards regression model was used to analyze the association between occupational hazard exposure and the risk of hypertension among the calcium carbide plant employees. Results The average age, mean systolic and diastolic blood pressure, proportion of males, smoking rate, and alcohol consumption rate in the exposure group were higher than those in the control group (P<0.05). Compared to baseline, both systolic and diastolic blood pressure levels increased in the exposure group and the control group at the end of the follow-up (P<0.05). At the end of the follow-up, the average differences between systolic/ diastolic blood pressure and baseline values in the exposure group were higher than those in the control group (P<0.05). During the follow-up period, a total of 223 cases of hypertension occurred, with a total follow-up of 2785 person-years, resulting in an incidence density of 8007.18 per 100000 person-years, an average age of onset of (35.90±8.22) years, and an average working age of onset of (2.69±1.97) years. The incidence density in the exposure group was 128.71% higher than that in the control group, and the risk of hypertension in the exposure group was 2.115 times that of the control group. The risk of hypertension was 2.199 times higher for men than for women, 1.344 times higher for those aged 30 and above than for those under 30, 1.546 times higher for smokers than for non-smokers, and 1.750 times higher for drinking workers than for non-drinking ones. The results of Cox proportional hazards regression modeling indicated that the hazard ratio (95%CI) of hypertension among the employees exposed to dust, noise, and carbon monoxide was 2.254 (1.703, 2.982), 1.594 (1.107, 2.295), and 1.567 (1.079, 2.274), respectively, when different covariates (gender, age, smoking, and alcohol consumption) were included. The results of Log-rank test showed that there were statistically significant differences in the distribution of disease-free survival between the exposure group and the control group (P<0.05). Conclusion Occupational exposures to dust, noise, and carbon monoxide may increase the risk of hypertension among calcium carbide plant workers.

Objective To investigate the clinical efficacy of Xinxuetong Oral Liquid in the treatment of patients with acute coronary syndrome(ACS).Methods A total of 80 patients with ACS of blood stasis syndrome who were hospitalized in Shunde Hospital of Guangzhou University of Chinese Medicine from January 2023 to September 2023 were randomly divided into the treatment group and control group according to random number table method,40 patients in each group.The patients in the two groups were given conventional western medicine treatment including lifestyle guidance,percutaneous coronary intervention(PCI),and conventional western medicine therapy.Additionally,the treatment group was treated with Xinxuetong Oral Liquid.The course of treatment for the two groups covered eight weeks.Before and after treatment the two groups were observed in the changes of traditional Chinese medicine(TCM)syndrome score,blood stasis syndrome score,angina pectoris score,blood lipid indicators,carotid ultrasonography indicators,echocardiography indicators,and serum levels of trimethylamine-N-oxide(TMAO),nitric oxide(NO),endothelin 1(ET-1),interleukin 8(IL-8),serine/threonine-protein kinase 1(AKT-1),and vascular endothelial growth factor A(VEGF-A).After treatment,the efficacy on TCM syndrome efficacy and the safety of the regimen in the two groups were evaluated.Results(1)During the trial,there were two cases of loss to follow-up and one case of withdrawal due to pneumonia,and eventually a total of 77 patients completed the full course of treatment,among which 39 patients were in the treatment group and 38 patients were in the control group.(2)After eight weeks of treatment,the total effective rate of the treatment group was 89.74％(35/39),and that of the control group was 63.16％(24/38).The intergroup comparison(tested by chi-square test)showed that the effective rate of TCM syndrome efficacy in the treatment group was significantly superior to that in the control group(P＜0.01).(3)After treatment,the scores of TCM symptoms such as chest pain,chest distress,symptom aggravation at night,and palpitation in the two groups,as well as the score of gloomy complexion in the treatment group,were significantly decreased compared with those before treatment(P＜0.05 or P＜0.01),and the decrease of scores of chest distress,symptom aggravation at night,and palpitation in the treatment group was significantly superior to that in the control group(P＜0.05 or P＜0.01).(4)After treatment,the blood stasis syndrome score and angina pectoris symptom score of the two groups of patients were significantly decreased compared with those before treatment(P＜0.01),and the decrease in the treatment group was significantly superior to that in the control group(P＜0.01).(5)After treatment,the serum TMAO,ET-1,IL-8,AKT-1,and VEGF-A levels in the two groups were significantly decreased compared with those before treatment(P＜0.01),and the serum NO level was significantly increased compared with that before treatment(P＜0.01).The decrease of serum TMAO,ET-1,IL-8,and AKT-1,VEGF-A levels and the increase of serum NO level in the treatment group were significantly superior to those of the control group(P＜0.05 or P＜0.01).(6)After treatment,the total cholesterol(TCHO)and low-density lipoprotein cholesterol(LDL-C)levels of the two groups(P＜0.01)and the triglyceride(TG)level of the treatment group(P＜0.05)were decreased significantly compared with those before treatment,while the high-density lipoprotein cholesterol(HDL-C)level of the treatment group was increased significantly compared with that before treatment(P＜0.01).No obvious changes of TG and HDL-C levels before and after treatment were shown in the control group(P＞0.05).The comparison of blood lipid indicators after treatment between groups showed that there were no statistically significant differences(P＞0.05).(7)After treatment,the carotid ultrasonography indicators of carotid intima-media thickness(IMT)and Crouse score of the carotid plaque in the two groups were significantly improved compared with those before treatment(P＜0.01).However,there was no statistical significance in the comparison of the two indicators between the two groups after treatment(P＞0.05).(8)The observation of echocardiography indicators showed that only the post-treatment left ventricular diameter(LVd)of the treatment group was significantly larger than that before treatment(P＜0.05),while no obvious changes of the other echocardiography indicators before and after treatment were shown in the two groups(P＞0.05).The comparison between the groups after treatment also showed no statistically significant differences(P＞0.05).(9)During the treatment,no serious drug-induced adverse reactions or drug-related severe cardiovascular events and complications occurred in the two groups.Conclusion The combination of Xinxuetong Oral Liquid with conventional western medicine treatment exerts certain efficacy and safety on improving the clinical symptoms of patients with ACS of blood stasis syndrome,and its therapeutic mechanism may be related to the improvement of blood lipid levels,inflammatory response,and TMAO level.

Objective:To investigate the clinical characteristics and risk factors associated with secondary systemic capillary leak syndrome (SSCLS) induced by acute organophosphorus pesticide poisoning (AOPP). The goal is to enhance clinical understanding of this complication and provide a theoretical foundation for the early identification of high-risk patients and the optimization of individualized treatment strategies.Methods:Clinical data were collected from patients admitted to the Emergency Department of Fuyang People’s Hospital Affiliated to Anhui Medical University between October 2019 and October 2024, who were diagnosed with acute dichlorvos poisoning. The clinical features of SSCLS were described, and patients were categorized into SSCLS and non-SSCLS groups. Binary multivariate logistic regression analysis was conducted on statistically significant indicators to identify independent risk factors for SSCLS. Receiver operating characteristic (ROC) curves were generated to evaluate the predictive value of these factors.Results:Among the 96 patients studied, 37 (38.5%) developed SSCLS. The median time from toxin ingestion to the onset of SSCLS was 3.0 (2.0-5.0) hours. In the 14 SSCLS survivors, the median duration of SSCLS was 50.0 (24-72) hours, whereas in the 23 non-survivors, it was 24.0 (12.0-35.0) hours. The mortality rate in the SSCLS group (62.16%, 23/37) was significantly higher than that in the non-SSCLS group (1.69%, 1/59) ( χ2=44.343, P<0.001). Blood toxin analysis detected trichlorfon components in 92 patients (95.83%). Binary multivariate logistic regression identified APACHE Ⅱ score and trichlorfon concentration (≥706.35 ng/mL) as independent risk factors for SSCLS ( P<0.05). ROC analysis revealed that the combination of these two factors had a higher predictive value ( P<0.05). Conclusions:In the diagnosis and treatment of acute dichlorvos (organophosphorus pesticide) poisoning, particular attention should be given to the combined toxic effects of dichlorvos and trichlorfon, which can lead to SSCLS. The onset and progression of SSCLS are rapid, and the condition is associated with a high mortality rate. Both APACHE Ⅱ scores and trichlorfon concentrations (≥706.35 ng/mL) are independent risk factors for the development of SSCLS, and their combined use enhances predictive accuracy. Early identification of high-risk patients and timely administration of individualized treatment are critical for reducing mortality rates. This revised abstract maintains the original meaning while improving clarity, flow, and readability. It ensures that the key points are presented in a structured and professional manner, suitable for a clinical audience.

Objective:To analyze the fitness of zirconia and lithium disilicate glass-ceramic onlays fab-ricated with direct and indirect computer-aided design and computer-aided manufacturing(CAD/CAM)technology in vitro.Methods:In the study,48 standardised typodont left mandibular first molars re-ceived standardised onlay preparation.Then,all the specimens were randomly divided into 4 groups.There were 12 specimens in each group.The preparation quality was checked under the stereo-microscope.All the specimens were fixed in typodonts.Subsequently,the typodonts were fixed in the dental simulators to simulate the oral conditions.In groups A and B,the digital impressions were ob-tained by using the intraoral scanner.In groups C and D,conventional impressions of polyether impres-sion material were obtained according to the instructions of the manufacturer using individual trays.The stone casts were made with type Ⅳ gypsum later.Then,all casts were digitized with the model scanner.Based on the data obtained from the scan,onlay restorations of all the groups were designed using the cor-responding software,the simulated cement thickness was set to 50 μm.Then,the final onlays restora-tions of all the groups were machined with the milling machines in lab.The fabrication materials were dif-ferent in groups.The specimens of groups A and C were fabricated with zirconia.While,the specimens of groups B and D were fabricated with lithium disilicate glass-ceramic.The marginal gap and internal gap of all restorations were analyzed by 3D replica technique,for each measurement,the specimen was digitised using the model scanner.Results:The marginal gap of the onlays fabricated with indirect digital impressions were smaller than that with direct digital impressions(P＜0.05).At the same time,the in-ternal gap of the onlays fabricated with indirect digital impressions were smaller than that with direct digi-tal impressions(P＜0.05).The marginal gap was larger in distal gingival than that in the other regions in all the groups(P＜0.05).Different fabrication materials,zirconia or lithium disilicate reinforced glass-ceramic,had no effect on onlay marginal and internal fit(P＞0.05).Conclusion:The marginal and in-ternal adaptation of the onlays fabricated with indirect digital impressions was better than with direct digital impressions.Zirconia and lithium disilicate reinforced glass-ceramic had no effect on the onlay adaptation.

Objective:To investigate the mediating effect of family resilience on the relationship between psychological resilience and demoralization in leukemia patients undergoing chemotherapy.Methods:A total of 240 leukemia patients hospitalized for chemotherapy in the Department of Hematology, the First Affiliated Hospital of Zhengzhou University, from January to December 2024 were selected by convenience sampling. The Basic Information Questionnaire, Family Hardiness Index (FHI), Connor-Davidson Resilience Scale (CD-RISC), and the Chinese version of the Demoralization Scale Ⅱ (DS-Ⅱ) were administered. Pearson correlation analysis was used to examine the associations among family resilience, psychological resilience, and demoralization. A structural equation model was constructed with AMOS 21.0 to verify the mediating effect. A total of 240 questionnaires were distributed, of which 232 were valid, yielding a valid response rate of 96.67% (232/240) .Results:The mean scores of the 232 patients were as follows: FHI (51.41±8.27), CD-RISC (51.84±7.96), and DS-Ⅱ (21.03±4.19). FHI was positively correlated with CD-RISC ( P<0.05), while DS-Ⅱ was negatively correlated with both FHI and CD-RISC ( P<0.05). Psychological resilience had a direct negative effect on demoralization ( P<0.01), and family resilience also had a direct negative effect on demoralization ( P<0.01). Family resilience partially mediated the relationship between psychological resilience and demoralization ( P<0.01), accounting for 59.96% (-0.289/-0.482) of the total effect. Conclusions:Psychological resilience and family resilience in leukemia patients undergoing chemotherapy were both at moderate levels, while demoralization was relatively high. Family resilience partially mediated the relationship between psychological resilience and demoralization.

Objective:To investigate the predictive value of anti-Müllerian hormone (AMH) on the outcome of microscopic testicular sperm extraction (micro-TESE) in patients with non-mosaic Klinefelter syndrome (KS) of the clinical data and to identify effective predictors for successful micro-TESE.Methods:A retrospective case-control study was conducted on the clinical data of 118 non-mosaic KS patients treated at the Center for Reproductive Medicine of the First Affiliated Hospital of Zhengzhou University between May 2018 and September 2023. Patients were divided into two groups based on whether sperm were successfully retrieved via micro-TESE: the sperm retrieved group ( n=45) and the no sperm retrieved group ( n=73). Differences between the two groups were compared, and multivariate logistic regression analysis was used to identify factors influencing sperm retrieval. Changes in testicular volume and sex hormone levels before and after surgery were also assessed. Results:The sperm retrieval rate was 38.1% (45/118). Patients in the sperm retrieved group were significantly younger [(26.93±3.80) years] than those in the no sperm retrieved group [(28.27±3.92) years, P=0.029], and the AMH level was significantly higher [0.44 (0.18, 1.13) μg/L] than that in the no sperm retrieved group [0.10 (0.03, 0.22) μg/L, P<0.001]. AMH was identified as an independent predictor of micro-TESE outcome in non-mosaic KS patients ( OR=7.867, 95% CI: 2.727-27.242, P=0.001). The area under the receiver operating characteristic curve was 0.802 (95% CI: 0.722-0.883), and the optimal reference threshold for AMH was ≥0.265 μg/L. Postoperatively, testosterone levels decreased significantly by a median of 0.27 μg/L ( P=0.019), while luteinizing hormone levels increased by a median of 2.08 U/L ( P=0.049), with a more significant decline in testosterone levels observed in the no sperm retrieved group by a median of 0.29 μg/L ( P=0.022). Conclusion:AMH can predict successful micro-TESE in non-mosaic KS patients, with higher AMH levels indicating a higher likelihood of success.
