AIM To investigate the action of rosiglitazone on blood glucose,blood lipid,and the vascular remodeling in rats fed with high-fructose diet. METHODS After fed with high-fructose diet for one month,rats were randomly divided into two groups:High-fructose diet group that continued feeding with high-fructose diet for another month; High-fructose diet+rosiglitazone group fed with high-fructose diet and rosiglitazone (5 mg?kg -1?d -1, dissolved in water) for one month. At last,one half of each group were anesthetized,and the fasting blood, obtained from heart,was used to detect blood glucose,blood lipid,blood insulin. The aorta and mesenteric artery were gotten from the other half of each group, fixed in formalin,sliced and HE dyed. Pathology analysis system was used to measure the remodeling indexes of aorta and mesenteric artery:Lumen ,media,media/lumen,media cross-section area. RESULTS Comparing high-fructose diet+rosiglitazone group with high-fructose diet group, rosiglitazone decreased blood pressure(16.0 kPa vs 18.0 kPa, P

Objective To explore the feasibility of constructing tissue engineered porcine corneal stroma with skin fibroblasts in vivo.Methods Skin fibroblasts were isolated from embryonic porcine,cultured and expanded in vitro.Cells were labeled with green fluorescence protein(GFP) gene by retro-viral infection.Cells at passage 3 were seeded on polyglycolic acid(PGA) non-woven fibers to form a cell-scaffold complex.The complexes were then implanted into porcines' corneal stroma after culturing in vitro for 1 week.Engineered stroma was observed continuously and harvested after 8 weeks for gross and histological evaluation.PGA with corneal stromal cells was served as control. Results The engineered tissue in the stroma gradually became transparent over a period of 8 weeks,showing no difference with the control group.Histologically,the engineered stromal lamellar was relatively regular and similar to the control.The implanted cells were confirmed by GFP expression under fluorescent microscope.By transmission electron microscopy examination, no significant difference in the diameter of collagen fiber was observed between the engineered stroma and normal stroma. Conclusion Tissue engineered corneal stroma may be formed with skin fibroblasts in porcine corneal microenvironment.

OBJECTIVETo compare the clinical results of early and delayed intramedullary nailing and locked plating for the treatment of multi-segments tibial fractures of type AO/ASIF-42C2.

METHODSBetween January 2010 and January 2013,45 patients with multi-segments closed tibial fractures of AO/ASIF-42C2 were treated by early primary intramedullary nailing and locked plating in 20 cases as early group and delayed in 25 cases as delayed group. In early group,20 cases included 13 males and 7 females with an average age of (37.9±14.3) years old ranging from 20 to 56 years;according to soft tissue injury Tscherne classification, 8 fractures were frade I,12 were grade II. In delayed group, 25 cases included 17 males and 8 females with an average age of (38.7±17.2) years old ranging from 24 to 55 years,4 fractures were grade I ,19 were grade II ,2 were grade III. The operative time, blood loss, hospital stay,fracture healing time and complications were recorded. At final follow-up, the Johner-Wruhs score were used to evaluate functional efficacy, and the posterior-anterior and lateral X-ray to evaluate fracture reduction and alignment.

RESULTSAll the patients were followed up for (12.5±2.5) months in early group and (13.2±2.8) months in delayed group (P>0.05). No wounds infections were happened. At the last follow-up, the mean range of knee joint was 10°-0°-120°. According to Johner-Wruhs scoring,there were 15 cases in excellent,3 in good,fair in 2 in early group; 21 in excellent,2 in good,2 in fair. The average operative time,blood loss had no significant differences between two groups (P>0.05), but hospital stay in early group was significantly shorter than those in delayed group(P<0.05). Average fracture healing time of early group and delayed group were (5.3±2.6) months and (6.0±2.9) months, respectively (P>0.05).

CONCLUSIONFor multi-segments tibial fractures of type AO/ASIF-42C2 with preoperative minor soft tissue injuries lighter of Tscherne grade I or II, early primary intramedullary nailing and locked plating does not significantly increase the postoperative incidence of soft tissue complications for patients. The early and delayed primary intramedullary nailing and locked plating for treatment of AO/ASIF-42C2 proximal third tibial fractures can get similar curative effect.

OBJECTIVETo study the prevalence of hepatitis B virus (HBV) genotype in 5 cities of Fujian province and the clinical implications of distinct genotypes in HBV-related liver diseases.

METHODSHBV genotype was determined by the restriction fragment length polymorphism analysis in patients with chronic HBV infection in 5 cities of Fujian province. The relationship between HBV genotype and its clinical implications was studied by multinomal logistic regression and correspondence analysis.

RESULTSOf the 431 HBV DNA positive patients detected by PCR, 275 (63.8%) belonged to HBV genotype B, 100 (23.2%) to genotype C, 51 (11.8%) to genotype D and D-mixed genotype. Genotype A, E and F were not found. Multinomal logistic regression showed that genotype B was more prevalent in Quanzhou and Sanming cities than in Fuzhou (P = 0.002, P = 0.006), and genotype B appeared significantly more common in asymptomatic carriers (ASC), chronic hepatitis B (CHB) and severe hepatitis (SH). Genotype C was most prevalent in patients with liver cirrhosis (LC) (47.0%) than in those with ASC (14.5%) and SH (14.7%) (P = 0.009, P < 0.001). The positive rate of hepatitis B e antigen was higher in patients with genotype C than in those with genotype B and genotype D (56.0% vs. 52.4%, P = 0.008, and 56.0% vs. 30.8%, P = 0.051, respectively). By correspondence analysis, genotype D and D-mixed genotype seemed to be correlated with hepatocellular carcinoma (HCC).

CONCLUSIONS(1) The major popular genotypes of HBV were B, C and D in Fujian. (2) Data of our study suggested that the geographic distribution of genotype B and C might be different in some cities of Fujian. (3) Genotype B might have a tendency to lead to SH in younger patients with chronic hepatitis B and the development of LC might be associated with genotype C among the elder patients. (4) Genotype D appeared to associate with development of HCC, which called for further study to confirm.

Objective To explore the correlation of serum matrix metalloproteinase-2 (MMP-2) and tissue metalloproteinase inhibitor-2 (TIMP-2) levels to carotid atherosclerosis plaque vulnerability in patients with anterior circulation infarction. Methods Sixty patients with anterior circulation infarction and 38 healthy volunteers were enrolled in this study. Color Doppler ultrasonography of the carotid artery was performed to determine the carotid intima-media thickness (IMT), Crouse plaque integral (CPI) score, and the total carotid plaque area (CPA). According to the nature of the carotid atherosclerosis plaque defined by ultrasonography, the patients were divided into vulnerable plaque (VP) group (33 cases), stable plaque (SP) group (27 cases), and no plaque (NP) group (38 cases). Serum MMP-2 and TIMP-2 levels were detected in these subjects using enzyme-linked immnosorbent assay (ELISA). Results Ultrasonography showed significantly greater/MT, CPI and CPA in VP group than in SP and NP groups (P<0.05). Serum MMP-2 level was significantly elevated in VP group as compared with that in SP and NP groups (P<0.05). Serum TIMP-2 level was significantly lower in VP group than in SP and NP groups (P<0.05). In VP group, serum MMP-2 level and MMP-2/TIMP-2 ratio were found to positively correlate to IMT, CPl and CPA (r=0.961, 0.966, and 0.804 for MMP-2, respectively, P<0.05;r=0.625, 0.709, and 0.651 for MMP-2/TIMP-2 ratio, respectively, P<0.05), while TIMP-2 was inversely correlated to IMT, CPI and CPA (r=-0.944, -0.996, and -0.859, respectively, P<0.05). Conclusion Serum MMP-2 and TIMP-2 levels and MMP-2/TIMP-2 ratio are closely correlated to carotid atherosclerosis plaque vulnerability.

OBJECTIVETo analyze the clinical characteristics, influencing factors and outcome of recurrent patients with early stage bulky cervical carcinoma.

METHODSBetween January 1(st) 2000 and December 31(st) 2009, 76 patients with stage Ib2 and IIa2 bulky cervical carcinoma developed recurrence and (or) metastasis. The recurrence time, recurrence location, recurrence-related factors, treatment and survival were analyzed.

RESULTSThe median follow up was 44 months (9-137 months). The overall recurrence and (or) metastasis rate was 22.6%. The 1-, 1-2, 3-5 and 5-year recurrence and (or) metastasis rates were 38.2%, 27.6%, 30.3% and 3.9%, respectively. The 5-year survival rate of local recurrence was 34.5%, that of distant metastasis was 23.6%, and that of distant metastasis with synchronous pelvic recurrence was 11.1%, (P = 0.555). The 5-year survival rate of patients who received surgery plus chemotherapy, radiation plus chemotherapy and chemotherapy alone after recurrence and (or) metastasis were 53.3%, 30.7% and 24.6%, respectively (P = 0.686). Univariate analysis demonstrated that tumor recurrence and (or) metastasis in patients of the stage Ib2 and IIa2 bulky cervical carcinoma were influenced by the disease stage, pelvic lymph node metastasis, deep cervical stromal invasion, lymphovascular tumor thrombus and pathological types. Multivariate regression analysis demonstrated that pelvic lymph node metastasis, lymphovascular tumor thrombus and pathological types were the key factors affecting the recurrence and (or) metastases of the stage Ib2 and IIa2 bulky cervical carcinoma. Subgroup analysis showed that pelvic lymph node metastasis and stage were the main factors affecting the local recurrence in those patients, and the pathological type, vascular tumor thrombus and pelvic lymph node metastasis were the main factors affecting the distant metastasis.

CONCLUSIONSRecurrence and(or) metastasis of early stage bulky cervical cancer are mostly happened within 2 years post operation. Patients with pelvic lymph node metastasis have high probability to develop local recurrence and distant metastasis. Patients with non-squamous cell carcinoma and lymphovascular tumor thrombus are more likely to develop distant metastasis. Neoadjuvant chemotherapy does not decrease local recurrence and distant metastasis in patients with stage Ib2 and IIa2 bulky cervical carcinoma. Individualized treatment is advised for recurrent patients.
