Objective To analyze the mediating role of coping styles on the relationship between psychological resilience and somatic symptoms in Chinese medical team members. Methods A total of 267 members from 24 Chinese medical teams were recruited as the study subjects using a convenience sampling method. The 10-item Connor Davidson Resilience Scale, the Simplified Coping Style Questionnaire, and the modified Somatic Symptom Scale developed by the research team were used to assess their psychological resilience, coping styles, and somatic symptoms. Structural equation modeling was applied to analyze the relationships among the variables and their mediating effects. Results The average scores for psychological resilience, positive coping, and negative coping among the study subjects were (30.4±5.9), (28.6±5.6), and (12.3±4.7) points, respectively. The median and the 25th and 75th percentiles of somatic symptom score were 4.0 (1.0-8.0) points. Somatic symptom scores were negatively correlated with psychological resilience and positive coping scores [Spearman correlation coefficients (r_S) were -0.396 and -0.367, respectively, both P<0.01], and positively correlated with negative coping scores (r_S=0.260, P<0.01). Structural equation modeling analysis revealed that the psychological resilience did not directly affect somatic symptoms [95% confidence interval (CI): -0.359 to 0.000]. Psychological resilience indirectly affected somatic symptoms through positive and negative coping, with a total indirect effect with 95% CI of -0.381 to -0.114. Positive coping and negative coping accounted for 83.7% and 16.3%, respectively, of the total indirect effect. Conclusion The coping styles play multiple parallel mediating roles between psychological resilience and somatic symptoms of Chinese medical team members. Improving psychological resilience and coping ability can help alleviate somatic symptoms and promote the mental health of Chinese medical team members.

This case report introduces Professor ZOU Wei 's experience of treating a patient with Wernicke encephalopathy using the "regulating spirit and promoting yang acupuncture method". The patient was diagnosed as spleen and stomach deficiency with internal liver wind. The treatment principle focused on regulating spirit and awakening the brain, strengthening the spleen, calming wind, and relaxing the tendons. Three groups of acupoints were selected: ①acupoints for awakening the brain by regulating spirit and unblocking meridians (Baihui [GV20], Qianshencong [EX-HN1] and bilateral Taiyang [EX-HN5], Fengchi [GB20]), etc.; ②acupoints for harmonizing the spleen, stomach, qi, and blood (bilateral Tianshu [ST25], Daheng [SP15], Taixi [KI3], etc.); ③acupoints for relaxing and softening the tendons (bilateral Waiguan [TE5], Hegu [LI4], Yanglingquan [GB34], Xuanzhong [GB39]).The needles were retained for 50 min per session, once daily, 7 days a week. After 16-week treatment, the patient was able to walk a few steps slowly with assistance, and other symptoms returned to normal. A two-month follow-up showed the patient's condition remained stable, walking distance further increased, and overall health significantly improved.

BACKGROUND:Observations from several clinical studies suggest a close relationship between hypertension and osteoporosis,but the causal relationship between hypertension and osteoporosis is unclear. OBJECTIVE:To determine whether there is a causal relationship between hypertension and osteoporosis,multisite bone mineral density and osteoporosis with fractures in Asian and European populations,respectively,using a comprehensive two-sample Mendelian randomized analysis. METHODS:Data of osteoporosis in Asian populations were obtained through Japan biological bank. Data of osteoporosis in European populations were obtained from UK Biobank,a British biological bank. Data of hypertension,multisite bone mineral density and osteoporosis with fractures were all from FinnGen R10 database. Inverse variance weighted method,MR-Egger regression method,weighted median method,weighted model method and simple model method were used to study the causal relationship between hypertension and osteoporosis,multisite bone mineral density and osteoporosis with fracture in Asian and European populations. Comprehensive sensitivity analysis was used to verify the robustness,heterogeneity and level pleiotropy of the results. Stsiger test was used to determine whether there was a reverse causal relationship between osteoporosis and hypertension. RESULTS AND CONCLUSION:In Asian populations,there was no significant genetic predictive causal relationship between hypertension and osteoporosis,and there was a positive causal relationship between hypertension and calcaneal bone mineral density. In European populations,hypertension had a negative causal relationship with osteoporosis,and there was no significant causal relationship between hypertension and systemic bone mineral density,calcaneal bone mineral density,forearm bone mineral density and osteoporosis with fracture. According to the stsiger test,there was no reverse causal relationship between osteoporosis,multiplesite bone mineral density,osteoporosis with fracture and hypertension in Asian and European populations. These results indicate that there is a causal relationship between hypertension and osteoporosis,that is,in Asian populations,hypertension and calcaneal bone mineral density show a positive causal relationship;in European populations,hypertension and osteoporosis show a negative causal relationship,but no reverse causal relationship.

Objective To explore the impact of Qiangxin Tang on myocardial fibrosis in rats with chronic heart failure by mediating myocardial mitochondrial autophagy through the Bcl-2/adenovirus E1B 19kDa interacting protein 3/NIP3 like protein X and FUN14domain-containing protein 1.Methods Forty Sprague Dawley rats were divided into five groups randomly by the random number table:sham operation group,model group,Qiangxin Tang group,Captopril group,and Qiangxin Tang+Captopril group,with a total of eight rats in each group.Only the sham operation group threaded without ligating the left coronary artery of the heart.In all the other groups,CHF rat models were established after myocardial infarction by ligating the left coronary artery of the heart.From the day after successful modeling,each group was given corresponding drugs by gavage,and the left ventricular myocardial tissue of each group was de-tected.Western blot was used to detect the expression of NIX,BNIP3,and FUNDC1 proteins in each group.ELISA was used to detect brain natriuretic peptide and cardiac troponin T level.Mitochondrial morphology was observed under transmission electron microscopy.Masson staining was used to observe left ventricular myocardial fibrosis.Results Compared with the sham surgery group,the expression of NIX,BNIP3 and FUNDC1 proteins in the model group was significantly reduced,while the levels of BNP and cTnT were significantly increased(P＜0.05).The left ventricular myocardial tissue showed significant fibrosisand mitochondrial swelling.Compared with the model group,the expression of NIX,BNIP3,and FUNDC1 proteins was significantly increased in Qiangxin Tang group and Captopril group,while the levels of BNP and cTnT were significantly decreased(P＜0.05).The left ventricular myocardial tissue fibrosis was sig-nificantly reduced,and the mitochondrial morphology was mildly altered.Compared with Qiangxin Tang group and Captopril group,the Qiangxin Tang+Captopril group showed significant improvement in the above indicators,and there was no significant difference in the in-dicators between Qiangxin Tang group and Captopril group.Conclusion Qiangxin Tang may promote mitochondrial autophagy and ensure the morphology and function of mitochondrial by upregulating the expression of NIX,BNIP3 and FUNDC1,thereby reducing myocardial injury and fibrosis.In addition,the combination of Qiangxin Tang and Captopril has a better therapeutic effect on CHF.

BACKGROUND:Studies at home and abroad have shown that sarcopenia is closely related to metabolites.At present,the relationship between the latest 1400 blood metabolites and sarcopenia is still unknown.OBJECTIVE:To analyze the causal relationship between 1 400 metabolites and sarcopenia and its relevance with cardiovascular disease using Mendelian randomization.METHODS:Genome-wide association study(GWAS)data of sarcopenia-related characteristics(grip strength,limb muscle lean body mass,and walking speed)were obtained from the OPEN GWAS website as outcome data.A GWAS containing 1 400 metabolites was used as an exposure factor,and single nucleotide polymorphisms significantly associated with exposure factors were selected as instrumental variables.The causal association between 1 400 metabolites and sarcopenia was analyzed by"TwoSampleMR"and"gwasglue"packages of R software(V4.3.2).The research methods included inverse variance weighting,MR-Eggeer regression intercept,weighted median method,and simple mode.Heterogeneity,pleiotropic,sensitivity and other verification analysis were performed.Finally,reverse Mendelian randomization analysis was performed.RESULTS AND CONCLUSION:(1)The causal relationship between 1 400 serum metabolites and sarcopenia was analyzed by inverse variance weighting.The results showed that 1-linoleoyl-2-linoleoyl-GPC(18:2/18:3)and glycodeoxycholate 3-sulfate were protective factors,and the risk of disease decreased with the increase of metabolites(P＜0.01).(2)Two unknown metabolites(X-12822 and X-15486)and trans-3,4-methyleneheptanoate were risk factors.With the increase of two unknown metabolites(X-12822 and X-15486),the degree of low grip strength of male hands increased.Similarly,with the increase of trans-3,4-methylene heptanoate,the risk of disease also increased(P＜0.01).(3)To conclude,1-linoleoyl-2-linoleoyl-GPC(18:2/18:3)and glycodeoxycholate 3-sulfate have inhibitory effects on sarcopenia.Two unknown metabolites(X-12822 and X-15486)and trans-3,4-methyleneheptanoate can promote sarcopenia.This may be a new idea and new basis for sarcopenia research and treatment in the future.This study will also provide a reference for the study of the role of related metabolites in the Chinese population.

OBJECTIVE To investigate the effects and potential mechanism of Qiangxin decoction on mitochondrion of rats with chronic heart failure(CHF).METHODS The CHF model was established by ligating the left anterior descending branch of the coronary artery.Modeled rats were divided into model group,Qiangxin decoction low-dose and high-dose groups(12.25,24.50 g/kg,calculated by crude drug),and chemical medicine group(Sacubitril valsartan sodium tablets,10.42 mg/kg),with 10 rats in each group;control group was set up without treatment.Each group of rats was orally administered with the corresponding medication or normal saline twice a day for 28 consecutive days.After the last medication,the contents of N-terminal pro-brain natriuretic peptide(NT-proBNP)and adenosine triphosphate(ATP)in serum and phosphatidic acid(PA)and cardiolipin(CL)in myocardial tissue were all detected;the pathological damage and collagen fibrosis of rat myocardial tissue were observed;the apoptosis of myocardial cells was determined;the ultrastructure of myocardial tissue was observed;the protein expressions of mitofusin 1(Mfn1),Mfn2,optic atrophy protein 1(OPA1)and dynamin-related protein 1(Drp1)were all detected in myocardial tissue.RESULTS Compared with control group,the serum content of NT-proBNP,apoptotic rate of myocardial cells,and relative expressions of S-OPA1 and Drp1 proteins were all increased significantly;serum content of ATP,contents of PA and CL,and relative expressions of Mfn1,Mfn2 and L-OPA1 proteins were all significantly reduced(P＜0.05).There were abnormal membrane tissue structure in various layers of myocardial tissue,degeneration and necrosis of myocardial cells,and severe fibrosis;the mitochondria were swollen,with reduced or absent cristae,and uneven matrix density.After intervention with Qiangxin decoction,the levels of the aforementioned quantitative indicators in serum and myocardial tissue of rats(excluding CL content in the Qiangxin decoction low-dose group)were significantly reversed(P＜0.05);the pathological damage of myocardial tissue had significantly improved,fibrosis had significantly reduced,mitochondrial morphology tended to be normal,cristae had increased,and matrix density was uniform.CONCLUSIONS Qiangxin decoction can regulate myocardial mitochondrial function and structural integrity of CHF rats,thereby improving myocardial energy metabolism and antagonizing myocardial fibrosis,the mechanism of which may be associated with activating PA/Mfn/CL signaling pathway.

OBJECTIVE To investigate the effects of Qiangxin decoction on myocardial mitochondrial and energy metabolism in rats with chronic heart failure （CHF） based on mitophagy. METHODS Male SD rats were collected to establish CHF model by ligating the left anterior descending branch of coronary artery. The successful modeling rats were divided into model group， Qiangxin decoction group [12.25 g/（kg·d）， calculated by crude drug]， captopril group [10.38 mg/（kg·d）]， and Qiangxin decoction+captopril group （the same usage and dosage as single drug group） according to a random number table method， with 8 rats in each group. Another 8 normal rats were selected and received threading in the left anterior descending branch of the coronary artery without ligation as the sham operation group. Starting from the second day after successful modeling， the rats in administration groups were given relevant drug intragastrically， twice a day， for consecutive 28 days. After the last medication， the levels of adenosine triphosphate （ATP）， adenosine monophosphate （AMP） and free fatty acid （FFA） in infarcted myocardial tissues were detected， the pathological changes and mitochondrial morphology of the infarcted myocardial tissue were observed， as well as the protein expressions of B cell lymphoma-2 （Bcl-2）， Bcl-2 related X protein （Bax）， TANK-binding kinase 1 （TBK1）， p62 were detected in each group. RESULTS Compared with the sham operation group， the infarcted myocardial tissue fibrosis was changed evidently， with a large number of mitochondrial swelling and fusion， and internal cristae rupture； the levels of AMP and FFA， the protein expressions of Bax and p62 were all increased or up-regulated significantly in infarcted myocardial tissue， while the level of ATP， and the protein expressions of Bcl-2 and TBK1 were all decreased or down-regulated significantly （P＜0.05）. Compared with the model group， the pathological changes of infarcted myocardial tissue and mitochondrial swelling had been improved； the levels of AMP and FFA， and the protein expressions of Bax and p62 in infarcted myocardial tissue were significantly decreased or down-regulated in administration groups， while the level of ATP， and the protein expressions of Bcl-2 and TBK1 were increased or up-regulated significantly （P＜0.05）. And the effect of Qiangxin decoction+captopril group was better than that of single drug group. CONCLUSIONS Qiangxin decoction can alleviate myocardial fibrosis and mitochondrial swelling in CHF rats， and improve their myocardial energy metabolism， which may be related to regulating the expression of Bcl-2， Bax， TBK1 and p62 proteins and promoting myocardial mitophagy.
