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 investigate the relationship between serum retinol-binding protein 4(RBP4) and gestational diabetes mellitus (GDM) in Chinese Han pregnant women.195 (23-42 years) pregnant women were recruited (July 2005 to December 2007) from the Department of Gynecology and Obstetric in Ruijin Hospital during their visiting for routine prenatal examination.99 subjects belonged to GDM group,and 96 belonged to the group with normal glucose tolerance (NGT).65 non-pregnant healthy women served as control.Serum RBP4 was measured using sandwich enzyme linked immunosorbent assay (ELISA).Pregnant women had higher level of serum RBP4 than that of non-pregnant control.The concentration of serum RBP4 was significantly increased in GDM group as compared with NGT group[(43.04±1.85 vs 33.84±2.17) rag/L,P<0.01].Multiple stepwise regression analysis showed that triglycerides and homeostasis assessment for insulin resistance (HOMA-IR) were independent variables of RBP4 (r2 =0.165) in pregnant women.The results suggest that serum RBP4 level is significantly increased in pregnant women.Women with GDM had even higher RBP4 level than that of normal pregnant women,and RBP4 levele was positively correlated with triglycerides and HOMA-IR.

OBJECTIVETo develop the first grade standard analytical reference material of bovine blood lead.

METHODSAccording to standards and technology specification of primary standard reference material (JJG1006-1994), ISO 17511, and volume-effect relationship, a bovine blood lead model was developed by adding acetate lead in the feed in dose of 2-5 mg x kg(-1) x d(-1). Cow blood was collected when blood lead concentration went up to low, medium and high concentration range (90-100, 190-200, 280-300 microg/L). Blood sample was kept in tube and frozen after irradiation. The samples were tested for homogeneity and stability. ID-MS method was used to measure the lead concentration through comparison with two standard lead samples from the USA NIST SRM 955b.

RESULTSSamples of the three lead concentrations showed uniformity by single factor analysis of variance (F = 0.61, 1.64, 0.28, respectively, P > 0.05) . After 14 months monitoring, the RSD was 0.85%, 1.05% and 0.49% (t = 0.787, 1.132, 0.854, respectively, P > 0.05). The characteristic and indefinite values were 102.4 +/- 5.5; 181.2 +/- 4.0; 304.5 +/- 3.9, respectively (unit: microg/L). The reproduction of the two USA NIST SRM 955b samples further showed our methods and procedures were correct. Our sample was stabile for four days at room temperature.

CONCLUSIONThe standard reference material of bovine in our research had reached the national standard material requirements.

Objective To investigate the frequency of CD4~+CD25~+FoxP3~+regulatory T cells (Treg)and the expression of the functional protein,FoxP3,in patients with active tuberculosis and the relationship between Treg and the pathogenesis of tuberculosis.Methods Forty-five patients with active tuberculosis(including 25 cases of pulmonary tuberculosis and 20 tuberculous lymphadenitis), 20 healthy controls,20 recovered tuberculosis patients and 6 patients with reactive hyperplasia in cer- vical lymph node were enrolled.The frequency of CD4~+ CD25~+ FoxP3~+ Treg in the peripheral blood was measured by flow cytometry.FoxP3 mRNA expression was determined by real-time reverse transcriptase-polymerase chain reaction(RT-PCR)and the expression of FoxP3 protein in lymphoid tissues was measured by immunohistochemistry.Results The frequency of natural Treg in the peripheral blood from the patients with active tuberculosis was 2.91%?0.23%,which was signifi- cantly higher than that of healthy control group(1.22%?0.18%)and recovered tuberculosis patients(1.50%?0.17%,P

It is commonly accepted that airway hyperresponsiveness (AHR) is a chronic airway inflammation although the exact mechanism of its pathogenesis is still unclear. In the past ten years, an epithelial defect hypothesis has gradually gained supports from the main stream. Airway epithelium is no longer considered only as a simple mechanic barrier but an active interface between the inner and outer environment. Bronchial epithelial cells play a critical role in maintenance of homeostasis in the airway local microenvironment through a wide range of physiologic functions including anti-oxidation, exocrine/endocrine secretions, mucus production and antigen presentation under health and stressed/inflamed/injured conditions. It is reasonably hypothesized that disruption of these functional processes or defects in airway epithelium integrity may be the initial steps leading to airway hyperresponsiveness such as in asthma and chronic obstructive pulmonary disease.

BACKGROUND: Catheter ablation is effective in restoring sinus rhythm and left atrial appendage closure (LAAC) is increasingly used for stroke prevention in patients with atrial fibrillation (AF). We aimed to observe the feasibility and safety of performing AF ablation and LAAC in a single (one-stop) procedure. METHODS: Consecutive AF patients who underwent the combined procedure of AF ablation and LAAC with WATCHMAN device between March 2017 and September 2018 were prospectively enrolled. Baseline and intra-procedural parameters were evaluated. Three-month and subsequent 1-year follow-up were performed in all and earlier-enrolled subjects, respectively. RESULTS: A total of 178 AF patients (94 males, 68.9 ± 8.1 years) underwent the one-stop procedure with CHA2DS2-VASc score 3.3 ± 1.5 and HAS-BLED score 1.6 ± 1.0, respectively. Pulmonary vein isolation was achieved in all patients while additional linear ablation was applied if the operator deemed necessary, yielding immediate ablation success rate of 98.9% (176/178). In the subsequent LAAC, satisfactory seal (residual leak <5 mm) was achieved in all patients. One stroke and four cardiac perforations occurred peri-operatively. At 3-month follow-up, sinus rhythm and satisfactory seal were maintained in 153/178 (86.0%) and 178/178 (100%) patients, respectively. One stroke and one delayed cardiac tamponade occurred, while no device-related thrombus or device migration was observed. During the 1-year follow-up for the earlier enrolled subjects, 52/72 (72.2%) of the patients maintained sinus rhythm. There was no stroke or systemic embolism observed. CONCLUSION Combining catheter ablation and LAAC in a single procedure can be successfully and safely performed in non-valvular AF patients of Chinese population.

Objective:To explore the clinicopathological characteristics and prognosis of patients with ovarian metastases from colorectal cancer.Methods:A total of 122 female patients with ovarian metastases from colorectal cancer underwent treatment in Cancer Hospital, Chinese Academy of Medical Sciences between 2010 and 2015 were recruited. The clinicopathological features, treatment details and survival data of these patients were retrospectively analyzed. Kaplan-Maier method was used for survival analysis, log rank test and Cox proportional hazards model were used for prognostic factor analysis.Results:The median overall survival (OS) was 19.7 months. The 1-year, 3-years and 5-years OS rates were 72.1%, 24.7% and 9.9%, respectively. A total of 99 (81.1%) patients underwent oophorectomy. The median OS of patients who underwent oophorectomy was 21.9 months, significantly longer than 10.3 months of patients without oophorectomy ( P<0.01). Ovary as the only site of metastasis, primary tumor resection, and oophorectomy were associated with improved survival (all P<0.01). Primary tumor resection and oophorectomy were independent prognostic factors for OS (both P<0.01). Conclusion:Patients with ovarian metastases from colorectal cancer might acquire a survival benefit from surgical resection of the primary tumor and ovaries.
