Journal of Zhejiang Chinese Medical University 2013;(11):1294-1296
[Objective] Probe the source of Nv’ke Baixiao Quanshu or Obstetrics and Gynecology Pandect compiled by Gong Juzhong in Ming Dynasty, explorate the content and academic idea. [Methods]Through investigating and surveying the different editions, col ating and organizing the contents, probe and analyse the writing motivation, content and main idea of the work. [Results] The most contents of Nu ’ke Baixiao Quanshu are inherited from an-other work named Jiaozhu Furen Liangfang with 8 contents:Regulating the menstrual period, praying for children, antenatal training, previous preparation for delivery, parturition, lying-in, difficult labouring. The rest of the contents is extracted from some other works. This work records disease symptoms and medicine, surgery, gynecology and gravidity in various internal organs. Referring ancient classics on disease causes and researching prescriptions and treatments, the author emphasized naturalizing liver, kidney and spleen in warm. Mr. Gong applied drugs corresponding to syndromes. In the Qiusi and Taihou parts, he discussed rationales of infertility, natural endowment and pre-natal and post-natal care and introduced methodology of pulse feeling to diagnose pregnancy, Yuanfang Chao’s twelve col ateral channels in nourishing and training fetus, medicine conditioning for pregnant women, daily regi-men, medicine prohibition, preparation of ante partum. [Conclusion] Nu ’ke Baixiao Quanshu is created by extracting. Mr gong learned widely from oth-er’s strong points and compiled with distinct academic view, significantly guiding development of clinical medicine in department of gynecology of tradi-tional Chinese medical science and formation of system of reproduction care. Yet, some theories like methodologies of gender-oriented reproduction and gender-shifting reproduction should be discarded.

BACKGROUND: Experimental and clinical experiences show that the surface roughness of dental restoration materials directly affects bacterial adhesion; in addition, the material composition and physicochemical properties are also important influencing factors. OBJECTIVE: To compare the bacterial adhesion of zirconia ceramics and nickel chromium al oy as oral materials. METHODS: Zirconia ceramics and nickel chromium al oy were respectively cut into 10 pieces of 3. 0 cm ×3.0 cm×0. 2 cm plate specimens. For each material, five pieces were subjected to surface polishing treatment, and the other five pieces were glazed. Surface roughness value of specimens was detected. Experimental strains of Streptococcus mutans was cultured on the specimen surface at 37 ℃ for 48 hours, and the amount of bacteria adhering to the specimen surface was detected. RESULTS AND CONCLUSION: Surface roughness of four groups of specimens showed no difference. The amount of bacteria that adhered to the polishing specimens of zirconia ceramics was significantly lower than that of nickel chromium al oy (P < 0.05), but no difference was found in the amount of bacteria adhering to the glazing specimens of nickel-chromium al oy and zirconia ceramics. These findings indicate that zirconia ceramics has better ability to inhibit bacterial adhesion than nickel-chromium al oy, especial y after glazing.

Objective: To evaluate the relationship between the levels of serum uric acid (SUA) and prevalence of coronary artery disease (CAD) by Meta analysis. Methods: We searched the databases of Pub Med, Elsevier and Web of Science for internationally published cohort study for the relationship between SUA levels and CAD prevalence and conducted a general analysisby using Stata software. Results: A total of 11 cohort study including 463,918 subjects were enrolled in this study. For both male and female genders, increase SUA level was the risk factor for CAD occurrence (RR=1.11, 95% CI 1.00-1.24) and (RR=1.24, 95% CI 1.15-1.34). Dose-response Meta-analysis indicated that by 1 mg/dl SUA elevation, the risk of CAD occurrence would increase 4.8% in male and 12.4% in female, the risk in female gender was higher than male. Conclusion: SUA level has been closely related to CAD prevalence.

Objective:To investigate if in vitro chemotherapy can induce the EMT progress in gastric cancer (GC) cells. Method:The GC cell line, SGC7901, was treated using 5-Fu at a concentration of 30 μg/mL. The residual cells after four cycles of 5-Fu therapy were named as SGC7901/Fu. The morphological changes and malignant biological features, including the invasiveness and clone formation ability and the characteristics of cancer stem cell and biomarkers of EMT between SGC7901 and SGC7901/Fu, were compared. Results:The SGC7901/Fu cells displayed a mesenchymal appearance, decreased the expression of epithelial markers, and increased the expression of mesenchymal markers. The 50% inhibitory concentrations in the SGC7901/Fu and SGC7901 cells were (43.8 ± 7.2) and (64.6 ± 5.5)μg/mL, respectively. The number of cells that migrated through the basement-membrane of the Transwell chamber was 51.4 ± 8.7 and 93.2 ± 9.5, respectively. The rate of clone formation was 5.2%± 1.0%and 13.2%± 2.2%, respectively. The portions of the CD44+/CD24-cells were 4.13%±0.81%and 7.97%±0.50%, respectively. All differences were statistically significant (P<0.05). Conclusion:The residual GC cells underwent EMT progress after 5-Fu treatment, with increased chemoresistance and ability of invasiveness and acquired the property of cancer stem cells.
