Rosiglitazone was used for intervention of atherosclerosis in diabetic rabbits.The results showed that the intima/medium thickness ratio,cross section area of plaque,and the expressions of NADPH oxidase p22phox,gp91 phox were decreased;while the total anti-oxidative ability was increased after administration of rosiglitazone as compared with the non-intervention group(all P<0.05).Compared with rosiglitazone treatment group,serum hepatocuprein leveI in rosiglitazone prevention group was increased,while serum malonaldehyde level decreased(both P<0.05).This study suggests that rosiglitazone may have the effect of reducing the oxidative stress and the formation of atherosclerotic plaque in diabetics.

BACKGROUND:Conservative treatment is mostly invalid in treatment of severe degenerative lumbar scoliosis-induced low back pain, so surgical intervention is general y required. Repair methods are decompression, rigid fixation, and selective interbody fusion for the“responsible vertebra”to re-establish normal lumbar curvature, spinal balance and good stability. OBJECTIVE:To investigate clinical curative effect of local decompression and selective interbody fusion with pedicle screw fixation technique for the treatment of degenerative lumbar scoliosis. METHODS:Data of 57 cases of degenerative lumbar scoliosis from Armed Police Corps Hospital of Hunan Province from January 2011 to January 2014 were retrospectively analyzed. According to clinical characteristics of the patients, selective fusion, local decompression and pedicle screw fixation were used for repair. The imaging analysis and Suk criteria were used to evaluate fixation, decompression and bone fusion. Japanese Orthopaedic Association scores were utilized to assess therapeutic effect. RESULTS AND CONCLUSION:(1) Operation time was 157-255 minutes, averagely 176 minutes. Amount of bleeding was 480-1 700 mL, averagely 835 mL. Postoperative drainage volume was 140-210 mL, averagely 155 mL. (2) 57 patients were fol owed up for 12-38 months. Postoperative X-ray revealed that Cobb’s angle was (3.8±2.1)° on the coronal plane after treatment, and the correction rate of lordosis was 54%. The sagittal Cobb’s angle was (6.3±10.5)°, and the correction rate of lordosis was 35%. According to Suk standard, the fusion rate of vertebra was 95%. According to low back pain score system recommended by Japanese Orthopaedic Association scores, the effective rate was 91%at the end of fol ow-up. (3) There were 2 cases of cerebrospinal fluid leakage, 1 case of nerve injury, and 1 case of pedicle screw failure, no infection, no blood vessel injury. (4) These findings suggest that according to imaging data and self clinical features, local decompression and selective interbody fusion with pedicle screw fixation technique for the treatment of degenerative lumbar scoliosis can rebuild and stabilize degenerative lumbar scoliosis in the coronal and sagittal planes to different degrees, with satisfactory clinical curative effect.

Objective To study on the thermic effect of food (TEF) of patients with chronic obstructive pulmonary disease(COPD).Methods Basal energy expenditure (BEE) of 12 male cases and resting energy expenditure (REE) of 11 male cases of COPD were detected by indirect calorimetry with metabolic cart. There were no significant difference in sex, age, height and body weight between two groups' e.g:TEF=REE-BEE.Results BEE and REE were 1114?208kcal/d,1433?136kcal/d respectively, the latter was higher 28% than BEE.Conclusion TEF increases significantly which may contributes to malnutrition and non-response to nutritional support in patients with COPD.

Objective To construct dual-luciferase reporter plasmids containing the wild type and mutant rat extracellular signal-regulat-ed kinase 1 (ERK1) gene 3' untranslated regions (UTR) which were used to detect rno-miR-15b-5p's putative target gene. Methods The rat ERK1 gene 3' UTR fragment was amplified by polymerase chain reaction (PCR) from PC12 cell cDNA and cloned into pmiR-RB-ReportTM vector. The mutant rat ERK1 gene 3' UTR fragment was obtained by overlap PCR and inserted into pmiR-RB-ReportTM vector. Successful wild type and mutant recombinant plasmids were confirmed by DNA sequencing. PC12 cells were co-transfected with rno-miR-15b-5p mim-ic and pmiR-ERK13' UTR or pmiR-ERK1-mut 3' UTR and then analyzed by dual-luciferase reporter assay system. The achieved mutation sequence of the target site TGCTGCT was mutated to CGAACGT and GTACACG, respectively. Results The wild-type reporter vector pmiR-ERK13' UTR and the mutant reporter vector pmiR-ERK1-mut 3' UTR were successfully constructed. The rno-miR-15b-5p mimic de-creased the activity of pmiR-ERK13' UTR plasmid (P<0.001) but did not decrease the activity of pmiR-ERK1-mut 3' UTR plasmid. Conclu-sion The recombinant pmiR-ERK13' UTR and pmiR-ERK1-mut 3' UTR plasmids were constructed successfully, and luciferase activities demonstrated that the 3' UTR of ERK1 gene might be a potential target of rno-miR-15b-5p.

OBJECTIVE To explore the predictive value of human telomerase RNA gene component(hTERC) gene amplification and high-risk human papilomavirus(HR-HPV) testing in cervical intraepithelial neoplasia(CIN) as a marker for early diagnosis of cervix carcinoma.METHODS Fluorescence in situ hybridization(FISH) was used to detect the amplification of hTERC of cervical epithelial cells in 72 cases.By using hybrid capture 2(HC-2),two types of the HR-HPV DNA(HPV16/18) of each case were detected.Then,the results were compared with the pathologic diagnosis.The dual-color probe we used was GLP TERC/CSP 3.HeLa cells and lymphocytes from normal marrow were the positive control,while the cervical specimens from healthy outpatients were the negative control.RESULTS hTERC Gene amplification of specimens was tested in 72 cases,the positive amplification rate of hTERC gene in the cervicitis/CINⅠgroup and normal,compared to the cervical carcinomas(100%) and CIN Ⅱ/Ⅲ(68.75%),which showed a significant difference.The rates in CINⅡ and CINⅢ were 60.00% and 83.33%,respectively,which showed a significant difference compared with normal and CINⅠ/inflammation groups.hTERC gene amplification was positive in both HeLa cells and lymphocytes from normal marrow and HC-2 testing was positive in 32 cases of patients containing 11 cases of CINⅡ/Ⅲ,3 cases of cervical cancer,18 cases of cervicitis/CIN1 diagnosed.The positive predictive value(PPV) and specificity(Sp) of hTERC for the high-grade CIN was significantly higher than the PPV and Sp of HC-2 HR-HPV testing.CONCLUSIONS hTERC Gene involves in the progression and occurrence of cervical intraepithelial neoplasia and cervical squamous carcinoma.As a marker for early diagnosis of cervical intraepithelial neoplasia and cervical squamous carcinoma,the FISH method for hTERC gene is more reliable to differentiate the malignant diseases from the benign ones in cervixes than HC-2 HR-HPV DNA testing.The combined detection of HR-HPV and hTERC gene will provide more effective and suitable management to enhance the early diagnosis rate of cervical intraepithelial neoplasia and cervical squamous carcinoma.
