Rheumatoid arthritis (RA) is a kind of chronic, progressive, multiple, invasive autoimmune disease with two chief cclinical manifestations arthrosynovitis and ex-arthrosis, easy to occur in middle-aged women, also occur in children and the elderly, is characterized by progressive and break out repeatedly. RA pathogenesis is complex, there is no special treatment, used in treatment of R drug varied, new drugs and new therapies also emerge in endlessly, main including non-steroidal anti-inflammatory drugs (NSAIDs), slow action anti-rheumatism medicine (SAARDs), glucocorticoids (GCs), biological agent, traditional Chinese medicine and traditional Chinese medicine preparations, domestic market for rheumatoid main drug treatment are NSAIDs, SAARDs, GCs, traditional Chinese medicine and traditional Chinese medicine preparations. Traditional Chinese medicine and traditional Chinese medi- cine preparations for the treatment of RA have its unique advantages, show the characteristics of overall adjustment, multi-level and multiple targets, and also can alleviate and against side effects of western medicine. In recent years, more and more get people's atten- tion. This paper reviewed the research progress and treatment features of commonly used therapeutic agents for the treatment of RA in recent years, which provides reference and basis for future medicine anti-RA.

BACKGROUNDRepair of anterior mitral leaflet (AML) prolapse is still a technical challenge for cardiac surgeons. It is an important issue to find a way to repair the AML prolapse with a reliable and reproducible technique.
METHODSBetween January 2002 and June 2009, the operation of chordal transfer based on the "edge-to-edge" technique was performed in 21 patients with serious mitral valve regurgitation because of prolapse of the anterior leaflet. After the operation, echocardiography was performed in each patient before discharge and at the time of follow-up.
RESULTSAll patients survived the operation. One patient required mitral valve replacement because of anterior leaflet perforation 3 days after the operation. The other patients were free from reoperation. At the time of follow-up, all these patients were in New York Heart Association (NYHA) functional class I. In all these patients, pre-discharge and follow-up echocardiography showed neither stenosis nor significant regurgitation of the mitral valve: the cross-sectional area of the mitral valve was 3.3 - 4.8 cm(2) (mean (3.78 ± 0.52) cm(2)), the mean regurgitation area was (0.45 ± 0.22) cm(2). At the same time, both dimension of left atrium and left ventricle reduced significantly (left atrium diameter: pre-operation (48.26 ± 11.12) mm, post-operation (37.57 ± 9.56) mm, P < 0.05; the end-diastolic diameter of the left ventricle: pre-operation (61.43 ± 8.24) mm, post-operation (42.35 ± 10.79) mm, P < 0.01).
CONCLUSION"Edge-to-edge" chordal transfer technique is a simple, reliable, and reproducible technique that can provide good results for repair of anterior leaflet prolapse of mitral valve.

BACKGROUNDIt is still a challenge for the cardiac surgeons to achieve adequate revascularization for diffused coronary artery disease (CAD). Coronary endarterectomy (CE) offers an alternative choice of coronary artery reconstruction and revascularization. In this study, short-term result of CE combined with coronary artery bypass graft (CABG) was discussed in the treatment for the diffused CAD.
METHODSFrom January 2012 to April 2014, 221 cases of CABG were performed by the same surgeon in our unit. Among these cases, 38 cases of CE + CABG were performed, which was about 17.2% (38/221) of the cohort. All these patients were divided into two groups: CE + CABG group (Group A) and CABG alone group (Group B). All clinical data were compared between the two groups, and postoperative complications and in-hospital mortality were analyzed. The categorical and continuous variables were analyzed by Chi-square test and Student's t-test respectively.
RESULTSDiabetes mellitus, hypertension, hyperlipidemia, and peripheral vascular disease were more common in group A. In this cohort, a total of 50 vessels were endarterectomized. Among them, CE was performed on left anterior descending artery in 11 cases, on right coronary artery in 29 cases, on diagonal artery in 3 cases, on intermediate artery in 2 cases, on obtuse marginal artery in 5 cases. There was no hospital mortality in both groups. The intro-aortic balloon pump was required in 3 cases in Group A (3/38), which was more often than that in Group B (3/183). At the time of follow-up, coronary computed tomography angiogram showed all the grafts with CE were patent (50/50). There is no cardio-related mortality in both groups. All these patients were free from coronary re-intervention.
CONCLUSIONSCoronary endarterectomy + CABG can offer satisfactory result for patients with diffused CAD in a short-term after the operation.

To explore the physiological role and biocatalytic properties of short-chain dehydrogenases from Pseudomonas fluorescens GIM1.49, we cloned the structural gene pfd and characterized its over-expressed product. The length of gene pfd was 684 bp encoding a short-chain dehydrogenase with 227 amino acid residues and calculated molecular mass of 24.2 kDa. The recombinant plasmid pET28b-pfd was constructed and functionally expressed in Escherichia coli BL21(DE3), resulting in the over-production of recombinant short-chain dehydrogenase PFD with a size of 28 kDa. The enzyme could oxidize alcohols including 4-chloro-3-hydroxbutanoate ester and reduce 4-chloro-acetoacetate ester using either NAD(H) or NADP(H) as coenzyme. The enzyme showed the highest activity against 4-chloro-3-hydroxbutanoate ester as substrate, with Km of 186.40 mmol/L and Vmax of 89.56 U/mg. When catalying the oxidative reaction, its optimal temperature was 12 degrees C and optimal pH was 10.5, in contrast to the values of 24 degrees C and pH 8.8 in the reductive reaction. The enzyme had high solvent tolerance and its activity was improved by the addition of Ca2+ (1 mmol/L) or EDTA (5 mmol/L). These results indicated that the enzyme from Pseudomonas fluorescens GIM1.49 was a novel short-chain dehydrogenase and might play a role in oxidative degradation of halogenated secondary alcohols.

The study is aimed to assess the genetic diversity and genetic relationship of 18 Sarcandra glabra resources from different populations,and guide parent selection of cross breeding between these resources. The molecular marker technique ISSR was used to investigate the genetic diversity of the 18 resources. Data was analyzed by POPGEN 32, and a cluster diagram was presented by UPGMA. One hundred and ninety-eight amplified fragments were obtained using 23 ISSR primers. One hundred and eighty-four polymorphic loci were identified. Nei's genetic diversity index (h) was 0.32, Shannon diversity index (I) was 0.485 4. The genetic similarity coefficient among the resources ranged from 0.383 8 to 0.878 8 in an average of 0.661 2. The genetic distance between sample S2 and sample S18 was the farthest, so as between sample S3 and sample S18 both Nei's genetic distance was 0.957 5, The genetic distance between sample S4 and sample S5 was the closest, the Nei's genetic distance was 0.129 2,and the sample S1, S2, S3, S7, S10 were significantly different from the others based on the clustering analysis, the three groups S2 vs S3, S2 vs S6, S2 vs S18 were the best parent group selection. There was a middle level of genetic differentiation in the resources. The genetic distance between resources gives useful information to guide parent selection of cross breeding.

OBJECTIVETo explore the mechanism of acupuncture for treatment of lumbar nerve root compression injury.
METHODSFifty healthy SD rats were randomly divided into 5 groups, a normal group, a model group treated by saline, a medication group treated with Caerulein, an acupuncture group treated with acupuncture at L5, L6 Jiaji (EX-B 2) and a warm needle group treated with acupuncture and moxibustion at L5, L6 Jiaji (EX-B 2). The lumbar nerve root compress injury model was made by placing microsilica gel tablet. After they were treated for 14 days, the compressed nerve root was taken and the ultra-microstructure changes of the injured nerve root were observed by electron microscope and changes of nitric oxide synthase (NOS) and calcitonin gene-related peptide (CGRP) expressions were investigated by ELISA assay.
RESULTSThe changes of ultra-microstructure of the nerve root were the most obvious in the model group and the changes in the medication group, the acupuncture group and the warming needle group reduced in order; the NOS activity and CGRP content in the nerve root tissue of the compressed area in the warm needle group were significantly reduced as compared with the model group (P < 0.05), but with no significant difference as compared with those in the normal group (P > 0.05).
CONCLUSIONWarm needle treatment can effectively maintain cellular form, and ultra-microstructures of nerve root dorsal root ganglia, and effectively inhibit the release of inflammatory factors NOS and CGRP.
