Objective To evaluate whether ABCD2 score can discriminate dizziness patients with and without stroke. Methods This retrospective case-control observational study was conducted in 403 hospitalized patients. According to the final discharge diagnosis, the patients were divided into two groups:the stroke group and non-stroke group. The areas un-der the receiver-operator curves and 95%confidence intervals were then generated to estimate the diagnostic value. Re-sults ABCD2 score was higher in stroke group than in non-stroke group. Conclusions ABCD2 score can be used to quickly identify dizziness patients with cerebrovascular diseases.

ObjectiveTo investigate the effects of comprehensive psychotherapy on depression,anxiety and gastrointestinal reactions in patients with lung or breast cancer.Methods96 cases with lung or breast cancer were randomly divided into psychotherapy group(n=48) and control group(n=48) which were both treated with routine chemotherapy.Those in the psychotherapy group concomitantly received comprehensive psychotherapy for 2 weeks.Their characters of Symptom Checklist 90(SCL-90) were measured,while those of Self-rating Anxiety Scale(SAS) and Self-rating Depression Scale(SDS) were also measured before and after treatment.ResultsThe scores of SCL-90 in patients with lung or breast cancer were increased compared with Chinese norm in somatization,depression,anxiety,phobic anxiety(P<0.01).From the 3rd week,the scores of SDS(41.2±3.7) and SAS(34.6±5.8) in the psychotherapy group were significantly lower than those in the control group(P<0.01),as well as the gastrointestinal reactions.ConclusionPsychotherapy can obviously decease the severity of depressive and anxious emotions and the gastrointestinal reactions.

Objective To study whether suprachiasmatic nucleus (SCN) slices are able to induce the molecular oscillations in NIH/3T3 fibroblast. Methods SCN slices from 10-day-old SD rat and NIH/3T3 cells were co-cultured in a serum-free condition. 24h mRNA profiles of Per1 and Rev-Erbα were measured in NIH/3T3 cells using real-time PCR. Results After co-cultured for 6 days, ten SCN slices can induce the significant daily oscillation of Per1 and Rev-Erba mRNA expression in NIH/3T3 cells (P<0.01). The peak time Rev-erbα and Per1 were at CT5 and CT11 respectively. Rev-Erbα oscillations were significant even with two SCN slices and 2 days co-culture (P<0.05). In contrast, Per1 expression fluctuation was not observed until more than 6 days of co-culture and with six SCN slices (P=0.031). Conclusion Diffusible signals release from SCN slices can regulate molecular rhythms in cultured fibroblasts. Rev-Erbα and Per1 don't start to oscillate at the same time, and Rev-Erbα is more sensitive to SCN signal.

Objective To explore the medical coping strategies and impact factors of patients with coronary heart disease in Wuhan.Methods Both medical coping strategies and impact factors of 90 patients with coronary heart disease in Wuhan were analyzed by using Spearman coefficient and multiple linear regression analysis,and compared with the norm of 701 cases.Results Compared with the norm,patients with coronary heart disease in Wuhan preferred less facing coping strategies and more avoidance coping strategies:(17.89±2.67) points vs.(19.48±3.81) points,(16.95±2.54) points vs.(14.44±2.97) points,and there were significant differences (t=2.146,P=0.035;t=1.994,P=0.048).The yielding coping strategies was indicated insignificant differences (t=1.758,P=0.173).The facing coping strategies were correlated with age (r=-0.212,P=0.036),education levels (r=0.190,P=0.041),family monthly income (r=-0.106,P=0.049) and disease course (r=0.327,P=0.017).The avoidance coping strategies were correlated with marital status (r=-0.304,P=0.013).The yielding coping strategies were correlated with length of disease(r=0.294,P=0.023)and therapy methods (r=0.308,P=0.017).Conclusions Based on patients' characteristics and impact factors,nursing staff should guide and encourage patients to use positive medical coping styles.

Objective To explore the relationship between the levels of plasma coagulation factors (F) and acute myocardial infarction (AMI) in low age period (<60 years old) and their diagnostic value in diagnosing AMI in low age period.Methods One hundred and sixty inpatients with low age AMI in the cardiology department of the Heze Municipal Hospital were selected as the case group,and contemporaneous 160 cases of low age non-AMI served as the control group.F Ⅱ,FⅦ,FⅧ,fibrinogen (Fg) and von willebrand (vWF) were measured with enzyme-linked immunoabsorbent anti-sandwich assay.The relationship between coagulation factors and low age AMI was analyzed with univariate and multivariate analysis,and their value for diagnosing low age AMI was evaluated with diagnostic test and receiver operating characteristics (ROC) curve.Results The univariate analysis showed that FⅡ,FⅦ,FⅧ and Fg levels had significantly statistical difference between the case group and control group(P<0.05),and the vWF level had no statistically difference(P>0.05).The multivariate analysis indicated that the FⅡ level≥ 14.27 μg/L and FⅦ level ≥22.99 μg/L were the independent risk factors for low age AMI.The value of FⅡ for diagnosing low age AMI was lower,and the optimal cut off value of Fg for diagnosing low age AMI was 22.99 μg/L,its area under ROC curve was 0.709 with a moderate diagnostic value,and the sensitivity (91.88%) and negative predictive value (86.02%) were higher,the false negative rate (13.98%) was lower,and the accuracy (70.94%) was moderate.Conclusion The FⅡ level ≥14.27 μg/L and Fg level ≥22.99 μg/L are the independent risk factors for low age AMI,and detecting the Fg level could have hint significance in diagnosing low age AMI.

Background: The side effects of glucocorticoid in treatment of systemic lupus erythematosus (SLE) have been the focus of debate, and our preliminary study indicates that ginsenosides can enhance the efficacy of dexamethasone. Objective: To observe the effects of ginsenosides combined with prednisone in SLE patients. Design, setting, participants and interventions: A total of 60 SLE patients from Department of Rheumatology and Immunology, Changhai Hospital, Second Military Medical University, were randomly divided into treatment group and control group, with 30 patients in each group. Patients in the treatment group were given routine treatment with prednisone plus ginsenosides, while those in the control group were given routine treatment with prednisone plus placebo. They were all treated for 3 months. Main outcome measures: After three-month treatment, syndrome score in traditional Chinese medicine (TCM), total response rate and symptom improvement rate were measured and evaluated. Results: Twenty-eight cases in treatment group and twenty-seven cases in control group were included in analysis. The total response rates in the treatment group and control group were 89.28% and 66.67% respectively, and there was a significant difference between the two groups (P<0.05). After treatment, the TCM syndrome scores in the two groups were lower than those before treatment (P<0.01), and prednisone plus ginsenosides was better in decreasing the TCM syndrome score than prednisone plus placebo (P<0.05). The symptoms were improved in the treatment group as compared with the control group (P<0.05). Conclusion: Prednisone combined with ginsenosides can increase the clinical effective rate and improve the clinical symptoms of SLE patients.

Objective To investigate the expression and significance of B lymphocyte stimulator (Blys) and its receptor BAFF (BAFF-R) in peripheral blood mononuclear cells (PBMCs) from patients with systemic lupus erythematosus (SLE). Methods The expression of Blys and BAFF-R was measured by flow cytometry in 90 pa-tients with SLE,which was compared with that of 45 healthy controls. The relationships between the expression of Blys, BAFF-R and other laboratory parameters as well as disease activity were analyzed. Results The expression of Blys and BAFF-R in PBMCs from patients with SLE was significantly elevated compared to healthy controls (P <0.001), so did the active group (P < 0.001) and inactive group (P < 0.001 and P < 0.01). The expression of Blys in PBMCs from active SLE patients was higher than that of inactive patients (P <0.05). However,there was no statisti-cal difference of BAFF-R between the two groups. The expression of Blys in PBMCs was positively related to SLEDAI (r =0.728,P <0.001) ,IgG and IgM(r=0.691,P<0.001 and r =0.453,P<0.01) ,but negatively related to C3 and CA (r = -0.510, P < 0.001 and r = -0.312, P < 0.05). The expression of Blys in dsDNA positive group was higher than those of dsDNA negative group (P < 0.01). The expression of Blys and BAFF-R in Cl qAb positive group was higher than those of ClqAb negative group as well (P <0.01). Conclusion The expression of Blys and its receptor BAFF-R in PBMCs from SLE is elevated ,which may reflect the disease activity and is related to the pro-duction of autoantibody. They might be involved in the pathogenesis of SLE.

Objective To explore the association between late-onset sporadic Parkinson' s disease (PD) and single nucleotide polymorphisms (SNPs) of Ca2+-dependent protease calpain inhibitor calpastatin (CAST) gene in a Chinese Han population.Methods 370 evaluable patients (221 male,149 female) with PD (mean age 65.2 ± 8.5 years) and 390 neurologically healthy controls (208 male,182 female) matched for gender,ethnicity,and area of residence.PD cases were identified from the PD cohort of the Chinese National Consortium on Neurodegenerative Diseases (www.chinapd.cn).A total of 24 tag-SNPs were genotyped capturing 95％ of the genetic variation across the CAST gene.Results There was no association found between any of the polymorphisms and PD in all models tested (co-dominant,dominant-effect and recessive-effect (P ＞ 0.05)).Similarly,none of the common haplotypes was associated with a risk for PD(P ＞ 0.05).Conclusion Results show no significant association between the CAST gene polymorphisms and late onset sporadic PD in the present population.

Objective:To study the feasibility of preserving the subvalvular structure during mitral valve replacement and whether it is more conducive to the recovery of cardiac function.Methods:The clinical data of 205 patients who underwent mitral valve replacement due to mitral insufficiency in Enshi Central Hospital from January 2017 to December 2020 were analyzed retrospectively. According to whether the subvalvular structure of mitral valve was preserved during operation, they were divided into three groups: group A was to preserve all the subvalvular structures of anterior and posterior mitral valve, group B retained all or part of the subvalvular structure of the posterior valve, in group C, all anterior and posterior subvalvular structures were removed. The operation time, cardiopulmonary bypass time and aortic occlusion time of patients in each group were counted. Postoperative ventilator use time, ICU stay time and incidence of complications; mitral flow velocities (MVE), left ventricular end diastolic dimension (LVED), left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) were rechecked by echocardiography at 1 week, 3 months and 6 months after operation.Results:There were no significant differences in operation time, cardiopulmonary bypass time, aortic occlusion time, ventilator use time and ICU stay time among the three groups before surgery ( P>0.05). There were no death cases in perioperative period, and all patients were cured and discharged from hospital. The results of cardiac color ultrasound showed that MVE, LVED, LVEF and LVFS were improved compared with those before operation. Postoperative ultrasound results showed no significant difference in MVE at 1 week, 3 months and 6 months ( P>0.05). At 1 week after surgery, LVED in group A was lower than that in group B and C: (44.90 ± 5.59) mm vs. (46.13 ± 6.15) mm, (48.33 ± 5.59) mm. The difference was statistically significant ( P<0.05). Three months after operation, LVED and LVFS in group A were higher than those in group B and group C: (43.37 ± 5.61) mm vs. (44.69 ± 5.45) mm and (53.42 ± 5.35) mm, (33.92 ± 3.34)% vs. (31.67 ± 3.20)% and (30.37 ± 6.96)%, respectively. The differences were statistically significant ( P<0.05). At 6 months after operation, LVED in group A was lower than that in group B and group C: (41.86 ± 3.27) mm vs. (47.85 ± 6.93) mm and (53.42 ± 8.17) mm. LVFS was higher than that in group B and group C: (33.42 ± 2.64) % vs. (32.18 ± 5.98) % and (32.28 ± 2.58) %, and the differences were statistically significant ( P<0.05). Conclusions:Preserving the whole subvalvular structure of mitral valve will not lead to prosthetic valve dysfunction and increase surgical complications. After operation, it showed better reduction of left ventricular end diastolic diameter and better left ventricular shortening rate, which was more conducive to the recovery of cardiac function.
