Objective To investigate the effect of noninvasive ventilator therapy on serum C-reactive protein (CRP), endothelin-1 (ET-1) and tumor necrosis factor-α (TNF-α) levels in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and its clinical significance. Methods One hundred cases of moder-ate and severe OSAHS patients were selected by the method of parallel opening. All of the patients were given health education requirement , quitting smoking and wine , low fat diet and exercise to lose weight and other con-ventional treatment. The patients were randomly divided into the treatment group of 42 cases with noninvasive ventilator treatment , 44 cases treated with conventional treatment , to observe the changes of serum CRP , ET-1 and TNF-α levels and PSG parameters after 12 weeks in two groups. Results Apnea hypopnea index (AHI), oxygen desaturation index (ODI), the lowest oxygen saturation (LSpO2), and the average oxygen saturation MSpO2 in OSAHS patients were significantly improved after treatment (P < 0.01), but the degree of improvement in the two groups after treatment was significantly higher than the control group (P < 0.01). Plasma CRP, ET-1 and TNF-α levels in the two groups after treatment were lower than before treatment (P < 0.05 or P < 0.01), but the treatment group was significantly higher than that of the control group ( P < 0 . 05 or P < 0 . 01 ) . Conclusion Noninvasive ventilator therapy in improving the OSAHS monitoring data of patients with PSG can effectively reduce the serum CRP, TNF-α, ET-1 level, reduce the body′s inflammatory reaction.

9α-hydroxy-4-androstene-3,17-dione (9-OH-AD) is an important intermediate in the steroidal drugs production. 3-ketosteroid-9α-hydroxylase (KSH), a two protein system of KshA and KshB, is a key-enzyme in the microbial steroid ring B-opening pathway. KSH catalyzes the transformation of 4-androstene-3,17-dione (AD) into 9-OH-AD specifically. In the present study, the putative KshA and KshB genes were cloned from Mycobacterium smegmatis mc(2)155 and Gordonia neofelifaecis NRRL B-59395 respectively, and were inserted into the expression vector pNIT, the co-expression plasmids of kshA-kshB were obtained and electroporated into Mycobacterium sp. NRRL B-3805 cells. The recombinants were used to transform steroids, the main product was characterized as 9α-hydroxy-4-androstene-3,17-dione (9-OH-AD), showing that kshA and kshB were expressed successfully. Different from the original strain Mycobacterium sp. NRRL B-3805 that accumulates 4-androstene-3,17-dione, the recombinants accumulates 9α-hydroxy-4-androstene-3,17-dione as the main product. This results indicates that the putative genes kshA, kshB encode active KshA and KshB, respectively. The process of biotransformation was investigated and the results show that phytosterol is the most suitable substrate for biotransformation, kshA and kshB from M. smegmatis mc(2)155 seemed to exhibit high activity, because the resultant recombinant of them catalyzed the biotransformation of phytosterol to 9-OH-AD in a percent conversion of 90%, which was much higher than that of G. neofelifaecis NRRL B-59395. This study on the manipulation of the ksh genes in Mycobacterium sp. NRRL B-3805 provides a new pathway for producing steroid medicines.

Objective To observe the bone metabolism of psoriatic arthritis (PsA) and investigate the roles of some bone metabolism markers such as tartrate-resistant acid phosphatase 5b (TRACP5),C-terminal telopeptide of collagen-Ⅰ (CTX-Ⅰ) and BALP in PsA patients with bone destructions.Methods Sixty-five cases of psoriatic arthritis,30 cases of psoriasis and 30 cases of healthy people were enrolled.Bone mineral densities of lumbar spines and the left femoral necks were measured for all PsA patients using dual energy X-ray absorptiometry.The Serum levels of TRACP5b,CTX-Ⅰ,BALP of healthy controls,Ps and PsA patients were measured.The PsA group was further divided into bone destruction group and none bone destruction group by image datasets.The levels of TRACP5b,CTX-Ⅰ,BALP,PsAJAI,ESR and CRP from each group were detected.Mann-Whitney and x2 test were used for statistic analysis.Results TRACP5b levels of the healthy controls,Ps and PsA patients were (0.9±0.4),(0.7±0.5) and (2.0±1.4) U/L respectively,and were significantly higher in the PsA patients than those of the other two groups (Z=-3.698,-3.638; P＜0.05).The CTX-Ⅰ levels of these three groups were (0.9±0.8),(0.6±0.7) and (2.6±1.8) ng/ml respectively,and were also dramatically higher in the PsA patients than the other two groups (Z=-5.262,-5.734; P＜0.05).BALP levels of each group were (22±4),(22±4) and (25±7) U/L,and were also evidently higher in the PsA patients than patients in the other two groups (Z=-2.214,-2.000; P＜0.05).Meanwhile,the levels of TRACP5b [(2.6±1.4) U/L],CTX-Ⅰ [(3.1±1.8) ng/ml] and BALP [(26±7) U/L] were significantly higher in bone destruction group than those in the none bone destruction group [(1.2±1.0) U/L,(1.9±1.6) ng/ml,(23±6) U/L,Z=-3.544,-3.429,-2.083; P＜0.05].Conclusion The high levels of TRACP5b,CTX-Ⅰ and BALP in PsA indicate that there is bone metabolism imbalances in PsA.And the high levels of TRACP5b,CTX-Ⅰ and BALP in the bone destruction group suggest that the rises of TRACP5,CTX-Ⅰ and BALP levels may be related with bone erosions.

Objective To study the exact function of human gene 5 transactivated by pre-S1 protein of hepatitis B virus(PS1TP5)by investigating the gene expression of PS1TP5 in yeast cells. Methods Reverse transcription-polymerase chain reaction(RT-PCR)was performed to amplify the gene of PS1TP5 using the mRNA of HepG2 cells as template and the gene was cloned into pGEM-T vector.The gene of PS1TP5 was cut from pGEM-T-PS1TP5 vector and cloned into yeast expressive plasmid pGBKT7,then pGBKT7-PS1TP5 was transformed into yeast cell AH109.The yeast protein was isolated and analyzed with sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE) and Western hybridization.Results PS1TP5 gene was successfully amplified and identified by DNA sequencing.The digested fragment was cloned into pGBKT7 vector and transformed into yeast cell AH109.The results of SDS-PAGE and Western assay showed that the relative molecular weight of the expressed product was about 36 950,and PS1TP5 protein existed in yeast cells.Conclusion The findings suggest that PS1TP5 can be successfully expressed in yeast cell.

Objective To investigate the effect of Jaceosidin on inflammatory response in gestational diabetes mellitus(GDM)rats and its mechanism.Methods The GDM rat model was established by intraperitoneal injection of streptozotocin into pregnant rats.The successfully established rats were separated into the GDM group,the Jaceosidin L,M,H groups and the Jaceosidin+CTCE-0214[stromal cell-derived factor-1α(SDF-1α)/C-X-C chemokine receptor 4(CXCR4)activator]group,with 10 rats in each group.Meantime,10 healthy pregnant rats were taken as the control group.The Jaceosidin L,M and H groups were gavaged with 2,3 and 4 mg/kg Jaceosidin,respectively.The Jaceosidin+CTCE-0214 group was intraperitoneally injected with 10 mg/kg CTCE-0214 and gavaged with 4 mg/kg Jaceosidin.The control group and the GDM group were given equal amounts of physiological saline.The fasting blood glucose,fasting insulin and insulin resistance index were compared between each group of rats.Enzyme-linked immunosorbent assay was applied to detect levels of IL-1β and TNF-α in placental tissue.HE staining was applied to observe pathological changes of placental tissue.Apoptosis of placental tissue was detected by TUNEL.Western blot assay was applied to detect levels of SDF-1α/CXCR4 pathway related proteins in placental tissue.Results The intervention of different doses of Jaceosidin in GDM rats reduced levels of fasting blood glucose,fasting insulin,insulin resistance index and proinflammatory cytokines,improved the placental injury and apoptosis of GDM rats,and inhibited the activation of SDF-1α/CXCR4 signaling pathway in a dose-dependent manner(P＜0.05).SDF-1α/CXCR4 activator combined Jaceosidin could inhibit the above effects of Jaceosidin.Conclusion Jaceosidin can reduce inflammation and insulin resistance in GDM rats by suppressing the activation of SDF-1 α/CXCR4 signaling pathway.

Objective To define the diagnostic criteria of cardiovascular magnetic resonance imaging in distinguishing isolated left ventricular noncompaction (LVNC) from lesser degrees of hypertrabeculation. Methods Twenty-five patients with LVNC, 39 with dilated cardiomyopathy ( DCM), 16 with aortic stenosis(AS), 15 with aortic regurgitation(AR) , 19 with hypertension (HT) and 22 normal subjects were enrolled in this study. Cardiac magnetic resonance imaging was performed to evaluate the left chamber diameter, functional parameters and noncompaction or hypertrabeculation of the left ventricle in diastole with one-way ANOVA. The left ventricle was divided into 17 segments for localizing all involved segments in this present study. Results The LVNC patients had the commonest myocardial segments involved (10±2)in all subjects. Each patient with LVNC was unexceptionally associated with apical noncompaction (17th segment) , which was seldom found in the other subjects. The lateral walls including 16th, 12th and 11th segments were the most vulnerable segments in all subjects, but nobody was found to involve the basal and mid septum including 2nd, 3rd, 8th and 9th segments. The end-diastolic NC/C (noncompaction/compaction) ratio was, on average, the greatest in patients with LVNC (3.3±0.6), compared with all other subjects(AS:1.0 ±0.3, AR:1.0 ±0.3,HT:0.8 ±0.1,healthy volunteers:0.9 ±0. 2) (F = 169. 62,P <0.05). Receiver operating characteristics analysis identified the end-diastolic NC/C ratio of>2.5 as a valuable parameter to distinguish LVNC from DCM.with values for sensitivity of 96.O%(24/25)and specificity of 94.9%(37/39),respectively.The mean number of NC/C ratio>2.5 segments in the LVNC patients was 4.0 ±2.0.while 8 of 39 patients with DCM had only one segment of NC/C ratio >2.5.Conclusions MRI is all exceUent imaging modality to diagnose LVNC and distinguish LIVNC from hypertrabeeulation.The criteria of LVNC is the NC/C ratio>2.5 in two or more than two segments of free ventricular walls associated with the left ventrieular apex involved.

To study the expression of angiotensin converting enzyme 2 (ACE2) and angiotensin (Ang) 1-7 specific receptor Mas protain in renal blood vessels of metabolic syndrome ( MS) rats and its anti-oxidative effect. A total of 80 male SD rats were divided into four groups: the normal control group (NC, the same volume of normal saline), the MS group (high fat diet), the MS + Astragali Radix group (MS + HQ, 6 g x kg(-1) x d(-1) in gavage) and the MS + Valsartan group (MS + XST, 30 mg x kg(-1) x d(-1) in gavage). After four weeks of intervention, their general indexes, biochemical indexes and blood pressure were measured; plasma and renal tissue Ang II, malondialdehyde (MDA) and superoxide demutase (SOD) levels were measured with radioimmunoassay. The protein expressions of Mas receptor, AT1R, ACE and ACE2 were detected by western blot analysis. According to the result, compared with the NC group, the MS group and the MS + HQ group showed significant increases in systolic and diastolic pressures, body weight, fasting glucose, fasting insulin, triglycerides, free fatty acid and Ang II level of MS rats (P < 0.05). The MS + XST group showed notable decreases in systolic and diastolic pressures than that of the MS group. The MS group showed significant increases in the SOD activity and NO level and decrease in the MDA level after being intervened with Astragali Radix. ACE and AT1R protein expressions in renal tissues of the MS group were higher than that in the NC group, but with lower ACE2 and -Mas receptor expressions (all P < 0.05). Compared with the MS group, the MS + HQ group showed significant increase in Mas receptor expression in renal tissues, whereas the MS + XST group showed notable decrease in AT1R (all P < 0.05). In conclusion, Astragali Radix can increase the Mas receptor expressions in renal tissues, decrease ACE expression and change local Ang II, MDA, NO and SOD in kidneys, so as to protect early damages in renal tissues.

OBJECTIVETo explore the prognostic values of Raf-1 kinase (Raf-1), phosphorylated mitogen extracellular kinase 1 (pMEK1), and phosphorylated extracellular signal-regulated protein kinase 1/2(pERK1/2) in hepatocellular carcinoma (HCC) patients.

METHODSWe assessed the expressions of Raf-1, pMEK1, and pERK1/2 in HCC using immunohistochemical techniques. The relationships between the expressions of Raf-1, pMEK1, and pERK1/2 and the prognosis were explored.

RESULTSThe over-expression rates of Raf-1, pMEK1, and pERK1/2 in HCC were 38.3%, 46.7%, and 38.3%, respectively. The over-expressions of Raf-1, pMEK1, and pERK1/2 were positively correlated with each other (P>0.05), but had no significant correlation with sex, age, α-fetoprotein, hepatitis B surface antigen status, the TNM stage, size,differentiation and vascular invasion of tumor, and liver cirrhosis (P>0.05). Univariate survival analysis and COX proportional hazard regression model showed that Raf-1 over-expression was an independent prognostic factor of poor survival (P<0.05).

CONCLUSIONRaf-1 over-expression is an independent marker for the patients of HCC, which may provide new clue in the future targeted therapy.
