0.05). There were no adverse events or severe adverse events in all these 72 cases. Conclusion Ozone is effective and safe in the treatment of bacterial vaginosis.

Objective To study the rules of lochia rubra and draw normal pattern chart of post-partum lochia prospectively. Methods Samples were collected from parturients who had given birth in our hospital from July to December in 2002 consecutively including 191 women with cesarean section (CS) ,and 187 with spontaneous delivery. The amount of blood loss was measured and recorded everyday from 24 hours postpartumly to the day that lochia rubra was over by checking the special sanitary pads with squares on. All subjects were followed up on the 42nd day after delivery and the charts collected. Results The mean duration of lochia rubra in spontaneous delivery and CS group were (33. 9?12. 0) days and (39. 6?13. 1) days, respectively; and the 95% CI were 10-57 days and 14 -65 days, respectively (P = 0. 006). More recurrent lochia cases were seen in the CS group than that in spontaneous delivery group (103 vs 28, 66. 5% vs 19. 9%). Conclusions The duration of lochia rubra of CS group is longer than that of spontaneous delivery group. The 95% CI of the duration of lochia rubra is: 10- 57 days in spontaneous delivery group while 14- 65 days in CS group. Lochia rubra will recurred several times during puerperium, especially in CS group.

Objective To retrospectivly analyze the value of Pap smear,liquid-based cells, colposcopy and colposcopic cervical biopsy in the diagnosis of cervical cancer. Methods 116 cases of cervical cancer were retrospectively analyzed, and the value of Pap smear,liquid-based cells ,colposcopy,and colposcopic cervical biopsy in the diagnosis of cervical cancer were investigated. Result 116 patients were pathologically diagnosed with cervical cancer before and after surgery. Pap smear was performed for 30 patients (25.9%) ,and 10 patients (33.3%) were detected with HSIL. Liquid-based cells was performed for47 patients (40.5%) ,and 25 patients (53.1%) were detected with HSIL. Colposcopy was performed for 99 patients (85.3%), and 75 patients (75.8 % ) were detected with HSIL or invasive cancer. Preoperative colposcopic biopsy was performed for 99 patients, and the pathological coincidence rate was 94.9%. There was no significant difference statistically between two cytology screening ( P ＞ 0.05 ). There was significant difference statistically between liquid-based cells and colposcopy ( P ＜ 0.01 ). There were significant differences statistically among liquid-based cells,colposcopy ,and colposcopic cervical biopsy ( P ＜0.01 ). Conclusion Cytology, colposcopy, colposcopic cervical biopsy could not be individually more complete and accurate detection of cervical cancer. Colposcopy,colposcopic biopsy than cytology had higher accurate rate of diagnosis of cervical cancer. A reasonable combination of multiple detection methods could improve the diagnostic accuracy of cervical cancer.

Objective To understand the influence of HBsAg+ pregnant woman on the persistence of hepatitis B surface antibody(HBsAb)of neonates in three years after the first"0,1,6"immunization,and the influences of regular examination every half-year and revaceination in time on maintaining the immune effect. Methods Twenty neonates born from HBsAg-mothers and 24 from HBsAg+ mothers were followed up for 3 years.And children whose HBsAb's titer faded or disappeared(unstable)received recombinate yeast-derived hepatitis B gene vaccine.The proportion of children with unstable HBsAb and the positive rate of HBsAb on 7 month-old and 3 year-old were compared. Results The unstable rate of HBsAb in HBsAg- and HBsAg+ groups were 20.0%(4/20)and 79.2%(19/24),respectively(P<0.05).The rate of revaccination in these two groups were significantly different.The positive rate of HBsAb in 7 month-old children of HBsAg-mothers was 100.0%(20/20)and 62.5%(15/24)in those of the HBsAg+ group(P<0.05).No statistically difference was detected between the two groups when followed up at 3 years of age[85.0%(17/20)vs 91.7%(22/24),P>0.05]. Conclusions HBsAg+ mothers would reduce the stability of HBsAb in their neonates within three years after the first"0,1,6"immunization,but the immune effect of vaccination against hepatitis B can be maintained through regular examination every half or one year and revaccination.

Objective: To investigate the relationship between human papilloma virus (HPV) gene types and cervical diseases. Methods:The subjects included women with HPV who were diagnosed in the Outpatient Department of the Third Affiliated Hospital of Sun Yat-sen University (Guangzhou, China) from March 1, 2010 to January 31, 2011. A total of 21 HPV DNA types were found in the women using DNA flow-though hybridization genotyping technique, and a questionnaire-type survey was conducted on these pa-tients. In this study, 256 cases of normal or inflamed cervix, 34 cases of cervical intraepithelial neoplasia I (CINⅠ), 61 cases of CINⅡor CINⅢ, and 9 cases of cervical cancer were analyzed. Results:The HPV infection rates were 18.4%in the normal cervical or inflam-mation group, 67.6%in the CINⅠgroup, 96.7%in the CINⅡor CINⅢgroup, and 100%in the cervical cancer group. The HPV in-fection rate was higher in the CIN I group than in the normal HPV infection or inflammation group (P<0.001) and was higher in the CIN Ⅱ or CIN Ⅲ groups than in the CIN I group (P<0.001). The main types of infection were HPV16 (44.2%), HPV58 (24.2%), HPV52 (11.6%), and HPV33 (8.4%) in the CIN groups. The main type of infection was HPV16 in the cervical cancer group (88.9%). Conclusion: Cases of cervical lesions are increasing. With this prevalence of HPV, considerable attention should be focused on HPV16-, 58-, 52-, and 33-related infections and cervical lesions. Among them, HPV16 infection is the primary cause of disease progres-sion and carcinogenesis.

Objective To evaluated the value of hysteroscopy and dilatation and curettage (DC) in diagnosis of endometrial cancer. Methods This retrospective analysis included clinical pathologic data of 3 676 patients with endometrial cancer from Jan. 1, 2000 to Dec. 31, 2010 in hospitals of endometrial cancer prevention projects in Guangdong Province. Results A total of 3 676 patients with endometrial cancer were divided into DC group (3 211 patients) and hysteroscopy group (465 patients). Compared to the results of pathological diagnosis, the accuracy rate between DC group and in hysteroscopy group were no statistically difference was 91.00%(2 922/3 211) vs 90.75%(422/465;χ2=0.030, P=0.862). The accuracy rate, sensitivity, specificity, positive predictive value and negative predictive value of cervical involvement between DC group and hysteroscopy group were 81.28%vs 86.45%(P<0.01), 24.78%vs 23.68%(P>0.05), 93.76%vs 98.71%(P<0.01),46.75%vs 78.26%(P<0.01) and 84.95%vs 86.88%(P>0.05), respectively. Rate of positive peritoneal cytology in DC group was 4.76%(153/3 211), and the rate was 3.23%(15/465) in hysteroscopy group, which were no statistically difference (χ2=2.206, P=0.137). There were no statistically difference in 5-year overall survival (91.02% vs 92.03%;χ2=0.033, P=0.856) and 5-year progression-free survival (89.81%vs 91.83%;χ2=1.508, P=0.219) between DC group and hysteroscopy group. Conclusions Hysteroscopy and dilatation and curettage is an effective method in diagnosis of endometrial cancer, especially hysteroscopy is better in diagnosis of cervical involvement. Hysteroscopy don′t improve risks of positive peritoneal cytology and don′t affect the prognosis of patients with endometrial cancer.

AIM:To investigate the inhibitory effects of recombinant human Mullerian inhibiting substance on cell proliferation in human ovarian carcinoma cells (OVCAR8 and SKOV3 cell lines). METHODS:The expression of MISIIR protein and the localization of MISIIR protein were analyzed by Western blotting and confocal spectral microscopy,respectively. Cell apoptosis and cell cycle were detected by flow cytometry (FCM). Cell viability was determined via MTT method. Clone formation test was used to detect oncogenicity in vitro.RESULTS:The MISIIR protein expression in OVCAR8 cells but not in SKOV3 cells was observed. MISIIR expression was seen on the OVCAR8 cell surface and in the cytoplasm with both antibodies. After treated with rhMIS for 48 h,the cell viability was significantly decreased in OVCAR8 cells. rhMIS inhibited the oncogenicity of OVCAR8 cells greatly. The cell apoptosis of OVCAR8 cell exposed to 10 mg/L rhMIS was (31.3±2.1)%,and OVCAR8 cells in the G_1 phase were increased by (70.4±3.0)%. Compared to SKOV3 cells the differences were significant (P<0.01). CONCLUSION:Recombinant human Mullerian inhibiting substance suppresses the growth of MISIIR-positive ovarian cancer cells by inducing apoptosis and cell cycle arrest. We predict that rhMIS might be a new target to treat human ovarian malignancies.

Objective To investigate the effects of clinical pathway-based teaching methods in clinical teaching of hematology. Methods Interns, which studied in department of hematology, were classified non-randomized into two groups. The interns in experimental group received idiopathic thrombocytopenic purpura (ITP) clinical pathway-based teaching. And the interns in the control group received the seventh edition textbook of medicine-based traditional teaching. All interns were oral tested when they finished two weeks period clinical studied of hematology. Meanwhile, a questionnaire designed for clinical pathway-based teaching was included in this test only for the experimental group. Results There were 32 interns recruited in the group of clinical pathway-based teaching and 38 interns in the control group of traditional teaching. There were statistically significant differences between the two groups in the fields of the key points about history of diseases ( = 0.0017), assessment of diagnostic criteria and differential diagnosis ( =0.0074), selection of laboratory examination items ( <0.0001) for ITP. The group of clinical pathway-based teaching achieved higher scores than the control group. However, there was no statistically significant difference between the two groups in the field of selection of first-line treatment measure of ITP ( = 0.1155) . Moreover, the control group achieved higher scores than the group of clinical pathway-based teaching in the field of how to treat ITP patients with first-line treatment failure ( =0.0003) . In addition,there were 93.8%interns in the experimental group accepted the new clinical pathway-based teaching tool in the survey. The open-ended question survey showed the clinical pathway teaching method was more simple, intuitive and standardizing than the traditional one. Conclusion The ITP clinical pathway, as an interns teaching tool of hematology, is helpful for understanding more clearly the diagnosis and treatment of ITP. However, an in-depth explanation is necessary combination with textbook of medicine study in the clinical teaching of ITP.
