OBJECTIVE: To study the effects of oxymatrine on joint inflammation and T cell subsets in CIA rats. METHODS Rats were randomly divided into 6 groups: normal control group, collagen-induced arthritis (CIA) model group, high-dose OMT (80 mg · kg-1 · d-1) group, middle-dose OMT (40 mg · kg-1 · d-1) group, low-dose OMT(20 mg · kg-1 · d-1) group and total gluco-side tripterygium (40 mg · kg-1 · d-1) group. To establish CIA model, all rats were injected with mixture of sheep type II collagen protein and Freunds complete adjuvant (FCA) intradermally at the right hindfoot, and injected again 1 week later at multipoints of the end of tail to boost the immunization. The intragastric administration procedure was performed from the first day after boosting immunization once a day for 4 weeks. Arthritis index (AI) was recorded every week. The blood sample was taken after the last administration to analyze T cell subsets by Flow Cytometry; serum TNF-α and IL-1β contents were measured by ELISA. Synovium of joint were fixed in 4% paraformaldehyde, and the hepatic pathological changes were observed. RESULTS: OMT could improve arthritis index (P < 0.05), decrease CD4+ T level (P < 0.05), increase CD8+ T level (P < 0.05), and also reduce CD4+/CD8+ ratio (P < 0.05). The levels of pro-inflammatory cytokines, TNF-α and IL-1β, were markedly decreased (P <0.01), too. Morphological observation indicated that OMT had significant inhibitory effect on synovial cells proliferation. CONCLUSION: OMT may play a therapeutic action on rheumatoid arthritis through adjusting the levels of T cells and cytokine. Copyright 2012 by the Chinese Pharmaceutical Association.

AIM: To discuss the clinical efficacy of fresh amniotic membrane ( AM ) during the microscopic adjustable suture surgery in children's intercommunity strabismus, in order to guide clinical treatment.
METHODS: With the clinical randomized control study (RCT), 60 (112 eyes) cases of patients in childhood who received microscopic strabismus surgery in our hospital were divided them into two different groups from Jan. 2010 to Oct. 2015. According to the application of AM on the basis of ophthalmology outpatient number, 30 cases (58 eyes) in group A were treated with rectus muscle recession surgery combined adjustable suture combined with AM. The other 30 cases (54 eyes) in group B were treated with rectus muscle recession surgery combined adjustable suture only. All patients in two groups were followed-up over 6mo after the strabismus surgery.
RESULTS:Twenty-seven cases ( 48 eyes ) of all the strabismus patients must be adjusted after strabismus surgery, and the eye position adjustment rate was 42.9%. At 1mo after surgery, eye position of 18 cases (29 eyes) can be adjusted in all patients, and 44. 8% (16 cases, 26 eyes ) in group A with the average of adjustment lengths was 2. 56±0. 64mm, and 5. 6% ( 2 cases, 3 eyes ) in group B, with the average of adjustment lengths was 0. 52±0. 28mm, the differences of the adjustment rate and the average of adjustment amount were both high statistically significant (χ2 =22.477, P<0. 01; t=16. 502, P<0. 01 ) between the two groups. Except of 3 cases who couldn't cooperate with eye position adjustment, they all received eye position adjustment in different degrees in one month after strabismus surgery,and after eye position adjustment, 27 cases (53 eyes) in group A got normal eye position, and the correction rate of eye position was 91. 4%, and 16 cases (28 eyes) in group B got normal eye position after eye position adjustment, the correction rate was 51. 9%, the differences of the correction rate were statistically significant (χ2=21. 827, P<0. 01) between the two groups.
CONCLUSION: The application of fresh AM in the microscopic adjustable suture strabismus surgery is exactly effective in treatment of children's intercommunity strabismus. It can significantly extend the adjustment time and increase the adjustment amount, and it also can statistically improve the controllability and achievement ratio for children's strabismus surgery.

Objective To evaluate the differentiation-inducing effect of phenylacetate on pancreatic carcinoma cells and underlying mechanism of RNA editing deaminase in cell proliferation and differentiation. Methods The effect of phenylacetate on cell proliferation and cell cycle were investigated in cultured pancreatic carcinoma BXPC-3 cell lines by methylthiazoletetrazolium( MTT) assay, and flow cytometry. The effect of phenylacetate on the expression of RNA editing deaminase (ADAR2 mRNA) in BXPC-3 cells and fresh pancreatic carcinoma specimen was evaluated by RT-PCR. Results ADAR1 mRNA expression was positive in human pancreatic carcinoma tissues and BXPC-3 cell lines. After application of 1.0 and 2.0 mmol/L phenylacetate for 24 h and 72 h, BXPC-3 cell growth inhibition rate increased, G0/G1 phase cells decreased, S phase cells increased, ADAR2 mRNA expression decreased ( P < 0.01 ). Conclusion ADAR2 mRNA played a vital role of regulation in the process of pancreatic carcinoma cells growth and differentiation. Phenylacetate could regulate the proliferation and differentiation of pancreatic carcinoma cells through the regulation of ADAR2 mRNA expression.

Objective To investigate the changing characteristics of myocardial movement in patients with dilated cardiomyopathy by three?di?mensional speckle tracking echocardiography(3D?STE). Methods The peak systolic global longitudinal train(GLS),global radial strain(GRS), global circumferential stain(GCS)and global area strain(GAS)of left ventricle were measured by 3D?STE technology in 69 patients with dilated cardiomyopathy. According to the left ventricular ejection fraction(LVEF),all patients were divided into group A(35%≤LVEF<50%)and group B (LVEF<35%). The differences of measurements were compared between two groups. The correlation between global myocardial strain in all direc?tions and left ventricular ejection fraction was analyzed. Results The GLS,GRS,GCS and GAS were significantly higher in group A than those in group B(P<0.01). The GLS,GRS,GCS and GAS were correlated with LVEF in group A(r=-0.871,0.610,-0.423,-0.797;P<0.05).The GCS,GRS and GAS were correlated with LVEF in group B(r=-0.517,0.368,-0.438;P<0.05). There was no significant correlation between GLS and LVEF in group B. Conclusion 3D?STE technology can be applied to evaluate the change of the myocardial movement. GLS is a promis?ing marker of the prognosis in patients with DCM.

OBJECTIVE: To elucidate the correlation between CKLF-like marvel transmembrane domain containing member (CMTM5) gene and the risk of in-stent restenosis (ISR) with coronary artery disease (CAD) patients and to detect the effects and mechanisms of CMTM5-stimulated genes on human vascular endothelial cells (ECs) proliferation and migration. METHODS: A total of 124 hospitalized patients in Shijitan Hospital were enrolled in this study. All the CAD patients were detected with platelet reactivity and grouped into two groups according to platelet reactivity; ISR was conformed by coronary angiography; RT-PCR method was used to detect CMTM5 gene expression; The CMTM5 over expression, reduction and control EC lines were established; Cell count, MTT, Brdu and flow cytometry methods were used to detect the proliferation of ECs, scratch and transwell experiments to test the migration of ECs, Western blot was used to detect signal path expressions. RESULTS: CMTM5 gene expression in HAPR (High on aspirin platelet reactivity) group was 1.72 times compared with No-HAPR group, which was significantly higher than No-HAPR group. HAPR group ISR rate was 25.8% (8 cases), the incidence of No-HAPR ISR group was 9.7% (9 cases), and the results showed that in HAPR group, the incidence of ISR was significantly higher than that in No-HAPR group (P=0.04, OR=0.04, 95%CI=1.16－7.52), which showed that CMTM5 gene was significantly correlated with the risk of ISR. In HAPR group ISR rate was 25.8% (8 cases), the incidence of ISR in No-HAPR group was 9.7% (9 cases), and the results showed that the risk of ISR in HAPR group was significantly higher than that in No-HAPR group. All the results showed that CMTM5 was significantly correlated with the risk of ISR in CAD patients (P < 0.05). CMTM5 overexpression inhibited the proliferation and migration ability of ECs (P < 0.05), PI3K/Akt signaling pathways were involved in the role of regulation on ECs. CONCLUSION Our results revealed that CMTM5 gene was closely related with ISR, CMTM5 overexpression may repress ECs proliferation and migration through regulating PI3K-Akt signaling.

OBJECTIVE: To elucidate the correlation between CKLF-like MARVEL transmembrane domain containing member 5 (CMTM5) gene and the risk of coronary artery disease (CAD), and to detect the effects of CMTM5 gene expression changes on the ability of adhesion and migration of THP-1 cells. METHODS: Using case-control method, a total of 700 hospitalized patients in Shijitan Hospital were enrolled in this study. CAD were diagnosed by coronary angiography, which was defined as at least one blood vessel diameter stenosis ≥50% according to the result of coronary angiography. Reverse transcription-polymerase chain reaction (RT-PCR) method was used to detect CMTM5 gene expression; enzyme linked immunosorbent assay (ELISA) method to detect the plasma level of CMTM5; and Logistic regression to analyze CMTM5 genes and the risk of CAD. Human vascular endothelial cells (ECs) and THP-1 cells were cultivated, adhesion and Transwells experiments were used to evaluate the chemotactic capabi-lity of CMTM5 gene on THP-1 cells. RESULTS: In this study, 350 CAD patients matched with 350 control patients were included. RT-PCR results revealed CMTM5 mRNA expression in CAD group was 3.45 times compared with control group, which was significantly higher than that in control group (P < 0.05). The levels of CMTM5 plasma protein in CAD group was (206.1±26.9) μg/L, which was significantly higher than that in control group (125.3±15.2) μg/L (P < 0.05). After adjusted for the risk factors of age, gender, BMI, smoking, hypertension, diabetes and hyperlipidemia, Logistic regression analysis results indicated that CMTM5 was the susceptibility factors of CAD, which still had significant correlation with CAD (P < 0.05). Adhesion and Transwells experiments results revealed that the numbers of adhesion and migration of THP-1 cells in CMTM5 overexpression ECs group (EO group) were significantly higher than that in lenti-mock infected ECs group (EO-MOCK group), non-infected ECs group (EN group), lenti-mock infected ECs group (ES-MOCK group), and CMTM5 suppression ECs group (ES group). On the contrary, the numbers of adhesion and migration of THP-1 cells in ES group were significantly lower than that in the other four groups (P < 0.01). CONCLUSION CMTM5 gene was closely related to the development of CAD. CMTM5 overexpression promoted the adhesion and migration of THP-1, which might play a part in the mechanisms of atherosclerosis and CAD.

OBJECTIVETo study the expression of carbonic anhydrase (CA) IX and its significance in molecular subtyping of breast carcinomas. METHODL MaxVision immunohistochemical staining was used to examine the expression of ER, PR, HER2, CK5/6, EGFR, and CA IX in 117 cases of breast invasive ductal carcinomas.

RESULTSThe patients' age ranged from 25 to 71 years (mean 49.6 years). All the 117 cases were subclassified into five subtypes, with 66 (56.4%) luminal A, 6(5.1%) luminal B, 10 (8.6%) HER2 positive, 20 (17.1%) basal-like, and 15 (12.8%) unclassified tumors. The expression of CA IX in luminal A and basal-like breast cancers was 13.6% (9/66) and 8/20, respectively, with a significant difference (P < 0.05). Among the luminal A cancers, the expression of CA IX in tumors > 2 cm (7/27, 25.9%) was significantly (P < 0.05) higher than that of tumors ≤ 2 cm (2/39, 5.1%). The expression of CA IX in grade 3 invasive ductal carcinoma (18/50, 36.0%) was significantly higher than that in grade 1 (2/21, 9.5%) and 2 (7/46, 15.2%) tumors (both P = 0.006). In CA IX-negative of invasive ductal carcinoma, the expression of ER and PR was 61.1% (55/90) and 55.6% (50/90), respectively; whereas in CA IX-positive cancers, the expression of ER and PR was 37.0% (10/27) and 29.6% (8/27), respectively. The expression of hormone receptors in CA IX-negative tumors was significantly higher than that in CA IX-positive tumors (for both ER and PR, P < 0.05).

CONCLUSIONSThe expression of CA IX correlates not only with molecular subtypes of breast cancer, but also with the grading, hormone receptors and diameter of mammary invasive ductal carcinoma. CA IX is a relative independent marker of poor prognosis in breast cancer.
