Objective To clone the genes related to pregnancy induced hypertension (PIH) for the study of PIH pathogenesis. Methods The differential expressed cDNA of PIH and normal pregnant placenta were cloned using modified polymerase chain reaction based subtractive hybridization. The differential cDNA were sequenced. Results Ammong 86 clones from subtractive hybridization, 14 clones containing differential expressed gene fragments in PIH and normal placenta were identified, and these might be the genes associated with PIH. Compared with the expressed sequence tags (EST) in dbEST of National Center for Biotechnology Information, it showed that 11 of them were known gene fragments, and three were unknown. The three unknown gene fragments were registered in GenBank, the accession number is AF 232216, AF 232217, AF 233648 respectively. Conclusions Fourteen PIH related genes were cloned with subtractive hybridization. A new approach to study on the pathogenesis of PIH is presented.

Objective To explore the feasibility of nasolabial sulcus flap transfer with autologous free skin graft to repair the alar defects after malignant tumor resection.Methods From January 2012 to January 2015,9 patients with malignant tumor were treated in the hospital.After complete tumor removal,the defect area being reconstructed was 1.5 cm × 1.3 cm to 2.5 cm × 2.5 cm.The defects of 9 patients were all restored with nasolabial sulcus flap combined with autologous free skin graft.Results The 9 patients were followed up for 6-18 months postoperatively.The nasolabial sulcus flap and autologous free skin graft were survived completely in all cases.Symmetrical alae were noted with slight edema within nasal cavity but without difficult ventilation.Scar was repaired in phase-two surgery.Conclusions Nasolabial sulcus flap combined with autologous free skin graft is an optional way in alar defects restoration.Further with secondary morphologic plasty,satisfactory surgical outcome can be achieved.

Caveolae are specialized lipid rafts that form flask-shaped invaginations of the plasma membrane. Many researches show that caveolae are involved in cell signaling and transport. Caveolin-1 is the major coat protein essential for the formation of caveolae. Recently, several reports indicated that the other caveolae-associated proteins, Cavins, are required for caveola formation and organization. It's worth noting that Cavin-1 could cooperate with Caveolin-1 to accommodate the structural integrity and function of caveolae. Here, we reviewed that the relationship between Cavins and Caveolins and explore the role of them in regulating caveolae.

Objective To assess the radial systolic function of left ventricle(LV) in patients with dilated cardiomyopathy(DCM) by velocity vector imaging(VVI).Methods Sixteen patients with DCM and twenty control subjects were detected by VVI.VVI data were collected from the six basal segments and six mid segments in parastenal LV short axis views.The radial systolic velocity(V) ,strain(ε) ,strain rate(SR),the time to peak systolic velocity(PTV) and the time to maximum strain(PTε) were measured with special software.The differene of the earliest and the latest time to peak velocity(T-max) and the standard deviation of time to peak velocity(T-SD) of 12 segments were calculated.Results Compared to the controlled group,patients with DCM had significantly lower radial V,ε and SR (P ＜0.01) in all the 12 segments,significantly longer PTV and PTε (P ＜ 0.05) in most segments, and significantly larger T-max and T-SD (P ＜0.05).Conclusions VVI is useful to assess the abnormalities in LV radial movement in patients with DCM and could provide more information about regional cardiac function.

Objective: To evaluate the efficacy of postoperative radiotherapy in the treatment of parotid gland carcinoma. Methods: Eighty-six postoperated patients with parotid gland carcinoma( 7 in stage Ⅰ, 28 in stage Ⅱ, 33 in stage Ⅲ and 18 in stage Ⅳ) were radiated by 60Co ?-ray or linear accelerator X-ray combined with electron beam. All patients were diagnosed by pathology and followed up for more than 5 years. Results: The five year survival rate and the local control rate were 73.3% and 87.2% respectively. Poor prognosis was observed in the cases with the neoplastic classification of undifferentiated carcinoma, sequamous cell carcinoma and malignant pleomorphic adenoma, but the better prognosis was obtained in the cases with acinic cell carcinoma and mucoepidermoid carcinoma. Poor prognosis was observed in the cases with stage Ⅲ and Ⅳ of clinical stage. Radiotherapy undertaken in 2 weeks after surgical operation gave higher 5- year survival ratio( 83.8%). The group given 51～60 Gy radiation showed 82.9% of five- year survival rate. Conclusion: The combination of surgery with radiation is effective in the treatment of parotid gland carcinoma.Radiation of 51～60 Gy 2 weeks after operation may result in better prognosis. Neoplastic type and clinical stage are important factors for prognosis.

Objective To analyze levofloxacin resistance in Helicobacter pylori (Hp) and the sequence difference of gyrA gene in levofloxacin resistance and sensitive Hp strains. To explore the function of gyrA gene mutation in the development of levofloxacin resistance Hp strain.Methods From July 2007 to December 2008 in Department of Gastroenterology, Jinhua People hospital of Zhejiang Province, the gastric mucosa from gastroscopy biopsy of chronic gastritis and peptic ulcer patients were cultured in Hp selective medium under microaerobic condition at 37 degrees for three to five days. The Hp strains were isolated and identified by oxidase test, catalase test,urease test and UreA gene detecting. The levofloxacin susceptibility was determined by E-test and then resistance and sensitive strains were screened. The genomic DNA of Hp strains was isolated. The gyrA gene was amplified by PCR and the sequences were analyzed. Results 38 clinical isolated Hp strains were passed the levofloxacin susceptibility E-test, among those the minimum inhibitory concentration (MIC) of 12 strains was over 1.0 μg/ml, the percentage of resistant strain was 31.58%, while the sensitive stains was 68.42%. The gyrA gene sequence result indicated 10 resistant strain with 261, 271 and 272 10 site mutation, 2 strains with C261A mutation, one strain with C261G mutation, two strains with G271A mutation, 2 strains with A272G mutation, 2 strains with C261A,G271T andA272G mutation, 1 strain with C261G and A272G mutation. However, no mutation sites were found in 26 sensitive strains. Conclusion The rate of levofloxacir-resistance in isolated clinical Hp strain was high. The drug-resistance was associated with 261,271 and 272. site mutation of gyrA gene.
