Objective] To observe the clinical efficacy of using Qu Feng Huo Luo Xie Zhuo tang to treat the chronic gouty arthritis of Tan Zhuo Zu Zhi Zheng. [Methods] From June 2013 to December 2014, 116 patients who got chronic gouty arthritis of Tan Zhuo Zu Zhi Zheng were chosen from the orthopedic outpatient cases in our hospital. All patients were equally divided into treatment group and control group by using random number table. The 58 patients of treatment group were treated with Qu Feng Huo Luo Xie Zhuo tang while the other 58 patients of the control group were treated with allopurino for 2 months. We analyzed the value of the Blood Uric Acid(BUA) and clinical efficacy before treatment and 2 months after treatment.[Results] The results showed that value of the BUA of two groups had no significant difference( P>0.05) before treatment, after 2 months, the value of the BUA of treatment group was lower than control group, the value of the BUA of two groups had significant difference( P<0.05).The rate of effective cases in treatment group was 87.9% while the control group was 68.9%, the clinical efficacy of the treatment group was better than the control group.There was statistical difference in the results of treatment between the groups( P<0.05).[Conclusion] Using Qu Feng Huo Luo Xie Zhuo tang to treat the chronic gouty arthritis of Tan Zhuo Zu Zhi Zheng could get good effect,and it was better than allopurinol which was often used in western medicine.It was worth to be researched and observed in clinic.

Objective: To understand social anxiety and relevant factors among graduate students under the normalization stage of COVID-19 epidemic prevention and control. Methods: Using convenience sampling method, an online questionnaire survey on graduate students from 5 universities in Jiangsu Province was conducted. Measurements used in the survey includes General Self Efficacy Scale (GSES), General Alienation Scale (GAS), Interaction Anxiousness Scale (IAS) and self made survey for basic information and household living conditions. Results: The overall score of graduate students self efficacy was (2.58±0.50). Average score was (30.68±6.22) for alienation, and (47.55±8.77) for interaction anxiety, with detection rate of social anxiety being 43.96%. Increased dependence on smartphones and electronic devices ( OR=1.86, 95%CI =1.32-2.61) and high alienation score (medium level: OR=2.06, 95%CI =1.45-2.92; high level: OR=5.19, 95%CI =1.00-27.00) were positively correlated with social anxiety. Increased communication with friends ( OR=0.65, 95%CI =0.47-0.90 and high self efficacy (medium level: OR= 0.37 , 95%CI =0.21-0.66; high level: OR=0.15, 95%CI =0.08-0.30) were negatively correlated with social anxiety. Conclusion At the normalization stage of COVID-19 epidemic prevention and control, social anxiety of graduate students is one of the mental health issues which need further attention. Participation in peer support helps prevent social anxiety through developing self efficacy, alleviating individual alienation, and reducing dependence on electronic devices among graduate students.

Objective:To explore the feasibility of using two-dimensional speckle tracking echocardiography for measuring right ventricular strain and function in healthy adults, and to analyze the impact of age and gender.Methods:This study is a cross-sectional study. Healthy adults who underwent physical examination in the Physical Examination Center of Beijing Hospital from January 1, 2020 to January 1, 2021 were included. Two researchers independently measured various right ventricular longitudinal strain indices using the Echopac software, including (global longitudinal strain (GLS), apical longitudinal strain (ALS), midventricle longitudinal strain (MLS), basal longitudinal strain (BLS), free wall GLS (FWGLS), free wall ALS (FWALS), free wall MLS (FWMLS) and free wall BLS (FWBLS)) as well as tricuspid annular plane systolic excursion (TAPSE) and right ventricle-fraction of area change (RVFAC). The above indicators were taken as the average of two physicians. The consistency of the measurements by two physicians was evaluated by the within-group correlation coefficient ( ICC). Results:A total of 233 subjects were included, including 137 males, aged (58.5±14.2) years. ICC values was all above 0.8 with excellent agreement. The values of FWGLS and GLS in healthy adults were -26.63% and -21.89%, respectively. There was no statistically significant difference in TAPSE ((2.06±0.41)cm vs. (2.10±0.39)cm, P=0.510) and RVFAC ((51.17±9.91)% vs. (50.89±8.65)%, P=0.826) between males and females. The values of various right ventricular long axis strain indicators (GLS, ALS, MLS, BLS, FWGLS, FWMLS, FWMLS, FWBLS) in females aged 18 to 40 and 41 to 65 years were higher than those in males of the same age (all P<0.05), while there was no statistically significant difference in the values of various right ventricular long axis strain indicators between the sexes in subjects aged 65 years and above (all P>0.05). In females, the right ventricular GLS, ALS, MLS, FWGLS, FWALS, FWMLS, and FWBLS values in the groups aged 18 to 40 and 41 to 65 years were significantly higher than those in the group aged 65 years and above (all P<0.05). In contrast, no significant differences were found in these indices among different age groups in males (all P>0.05). Conclusions:Using two-dimensional speckle tracking technology in echocardiography to measure right ventricular strain indicators is feasible and highly reproducible. Gender and age have an impact on right ventricular strain indicators.

Objective:To explore the risk factors for atrial fibrillation(AF)in elderly Chinese patients with severe valvular heart disease(VHD).Methods:This was a cross-sectional study and consecutively enrolled 978 elderly patients with severe VHD diagnosed in 18 Class A tertiary hospitals across the country from September 2021 to March 2022, including 322(32.9%)patients with concurrent AF.Clinical and echocardiographic data were collected to analyze the risk factors for AF.Results:Among VHD patients, compared with the non-AF group, the AF group was older, had a higher female ratio, higher diastolic blood pressure, higher proportions with cerebrovascular disease and chronic kidney disease, lower serum low density lipoprotein cholesterol and higher serum creatinine, amino-terminal A-type natriuretion peptide and glycosylated hemoglobin.As for echocardiographic parameters, the left atrial diameter was larger, the left ventricular end-diastolic diameter, interventricular septum thickness, and left ventricular posterior wall thickness were smaller in the AF group than in the non-AF group.All of the differences were statistically significant(all P<0.05). The results of multivariate Logistic regression analysis showed that the left atrial anteroposterior diameter increased( OR=1.166, P<0.01), the left ventricular end-diastolic diameter decreased( OR=0.929, P<0.01), and advanced age( OR=1.051, P<0.05)was an independent risk factor for elderly VHD patients with concurrent AF. Conclusions:In elderly patients with severe VHD, advanced age, an increased left atrial anteroposterior diameter, and a decreased left ventricular end-diastolic diameter were independently associated with AF.Therefore, evaluation of cardiac structure and regular follow-up should be performed in elderly patients with severe VHD for early intervention to reduce the incidence of AF.
