Objective To investigate infection rate of human papillomavirus as well as the correlation between cervical precancerous lesions and co-infection of human HPV,herpes simple virus-2 (HSV-2) and cytomegalovirus (CMV) in Chinese women of childbearing age in Kunming,Yunnan province.Methods A total of 2128 women (18-24,25-34,35-49 years of age),who had healthy care examination in our institute from January 2010 to March 2011,were selected prospectively in this study.The infection of HPV,HSV-2 and CMV were detected by real-time fluorescence quantitative polymerase chain reaction (FQ-PCR) and cervical precancerous lesions were determined by the ThinPrep liquid-based cytology test (TCT).Results The overall infection rates of high risk HPV (HR-HPV),HSV-2,CMV were 11.04％(235/2128),3.52％ (75/2128) and 5.26％ (112/2128),respectively.The HR-HPV infection rates in groups of Negative for Intraepithelial Lesion or Malignancy (NILM),Atypical Squamous Cells of Undetermined Significance (ASCUS),Low grade Squamous Intraepithelial Lesion (LSIL),High grade Squamous Intraepithelial Lesion(HSIL),and Squamous Cell Carcinoma (SCC) were 4.29％ (82/1912),55.93％ (66/118),84.62％ (44/52),93.19％ (41/44) and 2/2,respectively.HR-HPV infection rates was increased with the development of cervical lesion (r =0.644,P =0.000).No significant difference on the infection rates of HR-HPV and HSV-2 was identified between different age groups (x2 =2.979,P =0.226; x2 =0.798,P =0.671).The peak age groups for CMV infection (7.62％) were 18 to 24 years old and the infection rates of CMV decrease with age.No significant difference of HSV-2 and HR-HPV coinfection was found between the TCT-abnormal (3.24％,7/216) and control groups (2.41％,46/1912,x2 =0.557,P=0.455),and no relationship was found between HSV-2 and HR-HPV infection groups (OR =0.56,95％ CI:0.17-1.82).The infection of HR-HPV were related significantly with CMV infection (OR =3.14,95％ CI:1.25-7.86).Conclusion HR-HPV infection appears to be the key risk factor for cervical cancer and synergistic interaction may occur between CMV and HPV infections in the development of cervical lesion.

[Objective] Antifungal action of fat-soluble extracts from Bulbus Allii Cepae (BAC) by different extraction technology on 16 strains of dermatophytes was observed to supply evidence for the optimization of extraction technology for BAC. [Methods] Four methods were used for the extraction of fat-soluble extract from BAC and the antifungal action of the extract was tested by medium dilution method. [Results] Fat-soluble extract freshly extracted from BAC by ether had a strong in-vitro antifungal action and its minimum inhibitory concentration (MIC) was not over 6.25 mL?L-1 against 10 strains of fungi including Shanghai Epidermophytom floccosum and its MIC against other strains ranged 12.5 -50.0 mL?L-1. The minimum fungicidal concentration of fat-soluble extract freshly extracted from BAC by ether was as the same as MIC. Fat-soluble extract freshly extracted by ether had no antifungal action after water removal by heating. [Conclusion] The extraction technology of freshly extracted by ether without heating is a better method for BAC and the fat-soluble extract extracted by this method has a better antifungal action.

BACKGROUND: Thermosensitive hydrogel has made great progresses in drug carrier and tissue engineering. However, its phase-transition temperature is lower than human body temperature, so it has not been used as implants. OBJECTIVE: To prepare and evaluate the biocompatibility of a thermosensitive hydrogel poly-(N-isopropylacrylamide-co-N-hydroxymethylacrylamide)[P(NIPAAm-co-NHMPA)] In vitro so as to assess its safety as a medical implant.DESIGN, TIME AND SETTING: Material experiment was performed at the Central Laboratory of Union Hospital of Tongji Medical College, Huazhong University of Science & Technology and Key Laboratory of Biomedical Polymers, Ministry of Education, Wuhan University Chemical Department from January to October 2007.MATERIALS: L929 mice fibroblast line was provided by Professor Chen, Stomatology Hospital of Wuhan University. N-isopropylacrylamide and N-hydroxymethylacrylamide were purchased from Aldrich.METHODS: Using ammonium persulfate and tetramethylethylenediamine as oxidateion-reduction initiation system and N, N'-methylene bisacrylamide as crosslinking agent, mass fraction 8.5% N-hydroxymethylacrylamide was added to the reaction system. The N-isopropylacrylamide and N-hydroxymethylacrylamide were dissolved in deionized water and reacted with N, N'-methylene bisacrylamide, ammonium persulfate and tetramethylethylenediamine at room temperature for 3 hours. The colorless transparent cylinder gel was obtained, soaked in deionized water and dried.MAIN OUTCOME MEASURES: Biocompatibility in vitro of the material was validated by cytotoxicity test, cells/scaffolds interaction test, hemolysis test and pyrogen test in vitro.RESULTS: Synthesized hydrogel showed thermosensitive character as expected and the lower critical solution temperature was 38 ℃. The toxicity rate was grade 0-1. Through the scanning electron microscopy, cells and scaffolds were tightly attached, producing a perfect interface, and the shape of cells was all right. Hemolysis rate was 2.54%. No pyrogen reaction was found. CONCLUSION: P(NIPAAm-co-NHMPA) has been successfully prepared with good biocompatibility in vitro and might become a good medical implant for clinical use.
