Objective To investigate the effects of treatment of syphilis in pregnancy on perinatal prognosis. Methods Patients of syphilis in pregnancy from Hainan Provincial People′s Hospital and Haikou Municipal Maternal and Child Health Center during 1995.1 to 2001.1 were collected for retrospective analysis. Pregnant women with syphilis were divided into treated group and untreated group according to whether they received penicillin anti syphilis treatment or not during pregnancy. Results The total number of deliveries in the 2 hospitals during that period was 18 701, and 61 out of 9 805 women screened for syphilis were positive, giving an incidence of 6 2/1000. The perinatal mortality rates were 11 2% in treated group and 83 3% in untreated group, and incidences of congenital syphilis were 17 6% and 72 7% respectively. Conclusion Syphilis in pregnancy is a serious complication to harm the fetus. Screening of syphilis during pregnancy is necessary, and penicillin treatment is effective which may reduce the perinatal mortality rate and the birth of congenital syphilis baby.

From the practice of application of PBL teaching in biochemistry,we find that the PBL has obvious advantages in inability training,class course and knowledge application,but the PBL should be applied in limited theory-learning course.

Objective To compare the effects of autologous blood transfusion and allogenic blood transfusion on the patients undergoing selective operation of intervertebral fusion with cage. Methods Forty patients who underwent selective operation of intervertebral fusion with cage in the De?partment of Orthopedics of our hospital from September 2012 to June 2014 were recruited for the study,including 20 cases that received autologous blood transfusion only(group A)and 20 cases that received allogenic blood transfusion only(group B). Preoperative and postoperative results of blood routine examination,body temperature,postoperative recovery indicators and expense of blood transfusion were compared between the two groups. Results The postoperative erythrocyte and hemoglobin of the patients in group A were significantly higher than those in group B(P<0.05). When the amount of blood used during the operation reaches or exceeds 4 units,the expense of autologous blood transfusion was lower than that of allogenic blood transfusion. Conclusion Autologous blood transfusion contributes to higher levels of postoperative erythrocyte and hemoglo?bin. When a large amount of blood is used during an operation,autotransfusion can help to reduce the expense of blood transfusion.

Objective To investigate the feasibility and effectiveness of ‘ group-head responsibility teaching method' in the physiology experiment teaching.Methods Totally 422 students of clinical medicine major in 2010 grade were randomly divided into two groups:212 students in control and 210 in study group.For students in control group,principles,procedures,items of experiment and computer operation were first taught,then experiment was performed while for those in study group,initial procedures were firstly explained,then the group heads were called together to observe the experiment preformed by teacher,after that the group heads returned to assist other students performing the experiment.Finally,experiment success rates,scores of final-term experiment operation,theoretical exam and report of two groups were compared and analyzed.Meanwhile,questionnaire survey was conducted.Results Success rates were improved significantly in study group than in control group (x2 =37.42,P =0.0000).There were significant differences in operation scores (t =4.3213,P =0.0000),theoretical exam scores (t =6.8744,P =0.0000) and report scores (t =15.298,P =0.0000) between the two groups.Conclusions ‘ Group-head responsibility teaching method' is better than traditional lecture-style teaching method and it can promote comprehensive capabilities of students.
