Objective To explore the efficacy of hormone replacement therapy (HRT) for rheumatoid arthritis (RA).Methods The literature about HRT in the treatment of rheumatoid arthritis were searched.Eleven papers were subjected to a Meta-analysis and a heterogeneity test was conducted to evaluate the efficacy of HRT.Results HRT reduced the level of erythrocyte sedimentation rate (ESR) in RA patients (P=0.016),the SMD was-0.22(-0.40,-0.04); improved bone mineral density (BMD) in RA patients (P=0.022),the WMD was 2.83(0.41,5.26); decreased clinical parameters for disease activity evaluations of RA patients (P=0.048),the SMD was-0.19 (-0.38,0.00); decreased the level of C-reactive protein (CRP) in RA patients,the SMD was-0.08 (-0.37,0.21),but the difference was not statistically significant (P=0.591).Conclusion The findings from this Meta-analysis indicate that HRT can reduce the ESR level,improve clinical indexes and improve BMD level of RA patients.HRT may suppress disease activity and osteoporosis of RA patients,so it may be used as an auxiliary therapy in the treatment of RA.

A bacterial cell surface display technique based on an ice nucleation protein has been employed for the development of live vaccine against viral infection.Due to its ubiquitous ability to invade host cells,Salmonella typhimurium might be a good candidate for displaying viral antigens.We demonstrated the surface display of domain III of Japanese encephalitis virus E protein and the enhanced green fluorescent protein on S.typhimurium BRD509 using the ice nucleation protein.The effects of the motif in the ice nucleation protein on the effective display of integral protein were also investigated.The results showed that display motifs in the protein can target integral foreign protein on the surface of S.typhimurium BRD509.Moreover,recombinant strains with surface displayed viral proteins retained their invasiveness,suggesting that the recombinant S.typhimurium can be used as live vaccine vector for eliciting complete immunogenicity.The data may yield better understanding of the mechanism by which ice nucleation protein displays foreign proteins in the Salmonella strain.

Objectives: To explore the relationship between vascular active peptide, apelin level and blood pressure in a coastal population of Fujian province.
Methods: A total of 1031 subjects with the mean age of (55.1 ± 10.9) years in a coastal area of Fujian province were included in this cross-sectional study, and 416 subjects with male gender. The questionnaire survey, physical examination and plasma level of apelin measurement were conducted. Based on JNC-7 deifnition of hypertension, the subjects were divided into 3 groups: ① Hypertension group, the patients with systolic blood pressure (SBP)≥140 mmHg and/or diastolic blood pressure (DBP)≥90 mmHg, n=496. ② Pre-hypertension group, SBP at (120-139) mmHg and/or DBP at (80-89) mmHg without medication, n=314.③Normal BP group, SBP<120mmHg and DBP<80mmHg without medication, n=221. Based on 4 quartiles of apelin levels, the subjects were further divided into 4 groups:Q1 group, apelin<164.8 ng/ml, n=258. Q2 group, apelin at (164.8-<220.0) ng/ml, n=258. Q3 group, apelin at (220.0-283.1) ng/ml, n=258. Q4 group, apelin>283.1 ng/ml, n=257. One way analysis of variance, covariance analysis and multivariate linear regression analysis were used to study the
relationship between apelin level and BP.
Results: The apelin level in male gender (220.57 ± 78.87) pg/ml was lower than female gender (232.06 ± 81.17) pg/ml. Compared with Normal group, Pre-hypertension group had decreased apelin level, compared with Normal and Pre-hypertension groups, Hypertension group had decreased apelin level, P<0.05. Compared with Q1 group, Q2, Q3 groups presented decreased SBP, DBP and mean arterial blood pressure (MABP), and compared with other 3 groups, Q4 group had decreased SBP, DBP (not including Q2, Q3 groups) and MABP, P<0.05. With adjusted age and gender, SBP, DBP and MABP were signiifcantly different among 4 quartiles of apelin groups, P<0.05. Multivariate linear regression analysis indicated that SBP, DBP and MABP were negatively related to apelin level, such relationship remained the same after adjusting the other cardiovascular risk factors.
Conclusion: Apelin level dropping accompanying with BP increasing implies that vascular active peptide, apelin involved in BP regulation.

Objective To explore the correlation between illness conception, health seeking behavior and mental health status in recruits. Methods 865 recruits were evaluated by Symptom Checklist 90 (SCL-90), Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS) and Self-Rating Scale of Illness Conception and Health Seeking Behavior (SSICHSB) . Results (1) Except interpersonal sensitivity, depression and hostility, there were significantly differences in other factors of SCL-90 between recruit and the national norm. Somatization and anxiety scres were significantly higher ghan the military norm. The scores of SAS and SDS were significantly higher for recruits compared to national norm. (2) There was negative correlation between the total score, each factor score of SCL-90, the total score of SDS, the total score of SAS and SSICHSB; (3) Stepwise lines regression found three factors including anxiety, the total score of SAS and obsessiveness statistically significant, when the dependent variable was the total score of SSICHSB. Conclusion There are obvious somatization,anxiety and depression in recruits. The more obvious the symptoms are, the more passive the illness conception and health seeking behavior are.

Objective To study the expressions of the tumor suppressor gene TSH receptor( TSHR),P16, and RAS in papillary thyroid carcinoma ( PTC ) , and the correlation between the occurrence of tumor and the aberrant promoter hypermethylation of three tumor suppressor genes. Methods RT-PCR was used to detect the mRNA expression of three tumor suppressor genes in tissues of 50 cases of PTC ,20 cases of nodular goiter,and 12 cases of thyroid adenoma. The promoter methylation status of three tumor suppressor genes was examined by methylation-specific PCR technique( MSP). Gene sequencing was used to test if the hypermethylation existed in the promoter of three tumor suppressor genes. Results In 68.0% (34/50) TSHR gene, 54.0% (27/50) P16 gene, and 60.0% ( 30/50 ) RAS gene in PTCs, hypermethylation in promoter region was detected, the respective results 21.9% (7/32) , 15. 6% (5/32) ,and 31. 3% (10/32) were found in control tissues. The rates of the three genes with promoter hypermethylation in PTC were significantly higher than those in control tissues ( all P<0. 05). The mRNA expressions of TSHR,P16,and RAS were significantly lower in PTC than those in control tissues (0. 41 ± 0.11 vs 0.63±0. 08,0. 51±0. 17 vs 0. 72±0. 22,0. 56±0. 10 vs 0. 67±0. 16, all P<0. 05). The sequencing confirmed that there was CC to TC transmission in the promoters of three tumor suppressor genes. Conclusions The methylation of three tumor suppressor genes in promoter region is a common molecule event and may be involved in the genesis and development of human PTC.

Objective To investigate the efficacy of computer-assisted postural balance training system combined with Bobath balance training on balance disorders after cerebellar stroke.Methods Forty patients with balance disorders after cerebellar stroke were randomly divided into either a combined training group or a control group (n =20 in each group).The control group was trained with Bobath balance training and routine rehabilitation treatment.On the basis of this,the combined training group used the computerassisted postural balance training system for rehabilitation treatment.The balance function,activities of daily living and motor function were evaluated with the Berg Balance Scale (BBS),modified Barthel Index,mBI)and Fugl-Meyer Assessment (FMA) before and after treatment,and the computer-assisted postural balance training system was used to conduct the postural balance ability according to the center of gravity track length,rectangle area of track,and peripheral area of track.Results There were no significant differences in various indexes before treatment between the patients of both groups.The scores of BBS,mBI and FMA after treatment were increased obviously (all P ＜ 0.001).The the center of gravity track length,rectangle area of track,and peripheral area of track were decreased compared before treatment (P ＜0.001 or 0.05).In addition to the FMA score,all the indexes of the combined training group after treatment were significantly better than those of the control group (all P＜0.05).Conclusions On the basis of Bobath balance training,using computer-assisted postural balance training system can obviously improve the balance disorder and extremities motion ability after cerebellar stroke,and thus improving the activities of daily living in cerebellar stroke patients.

Objective To systematically review the effectiveness and safety of statins for chronic obstructive pulmonary diseases (COPD) combining with pulmonary hypertension (PH).Methods The electronic searches in databases of PubMed,EMbase,the Cochrane Library,Web of Science,CBM,CNKI,VIP and Wanfang Data were conducted from the date of their establishment to January 2016 and the references of the include studies were also retrieved for collecting randomized controlled trials (RCTs) or quasi-RCTs on statins treating COPD combining with PH.Two researchers independenlty screened the literature according to the inclusion and exclusion criteria,extracted the data,assessed the quality of the included studies by adopting the Cochrane collaboration' s tool for assessing risk of bias,and performed Meta-analysis by using RevMan 5.3 software.Results A total of 24 studies involving 1 587 cases were included.The results of Meta-analysis showed that:compared with the control group,simvastatin significantly improved FEV1 [MD =0.23,95％ CI:0.16-0.31,P ＜ 0.000 01],FEV1 ％ [MD =6.73,95％ CI:1.34-12.12,P =0.01],FVC [MD =0.39,95％ CI:0.34-0.45,P ＜ 0.000 01],6 minutes walk distance (6MWD)· [MD=59.09,95％CI:54.24-63.93,P ＜0.000 01] and decreased mPAP [MD=6.73,95％ CI:1.34-12.12,P =0.01],SPAP [MD =-4.53,95 ％ CI =-8.87--0.19,P =0.04].Atorvastatin significantly improved FEV1 [MD =6.22,95 ％ CI:2.51-9.93,P =0.001] and 6 MWD [MD =24.10,95 ％ CI:12.98-35.23,P ＜ 0.000 1] and decreased sPAP [MD =-6.44,95％CI:-7.95--4.93,P＜0.00001] andmPAP [MD=-3.51,95％CI:-5.81--1.22,P=0.003].But no significant difference was found in the improvement of FEV1,FVC or FEV1/FVC.Fluvastatin significantly decreased sPAP [MD=-5.89,95％ CI:-6.99--4.79,P ＜0.000 01].There was a significant decrease in the Borg dyspnoea score in statins group [MD =-3.37,95％ CI:-4.61--2.14,P ＜ 0.000 01] as compared with the controls.In addition,the incidence of adverse drug reactions (ADRs) was similar between statins and the control group.Conclusion Current evidence suggests that statins may decrease pulmonary hypertension in patients with COPD combining with PH.However,high-quality clinical trials with large sample size are needed to verify whether the improvement of pulmonary function,6MWD and Borg dyspnoea score are the class effect or the incidence of ADRs is disparate among different statins.
