Objective To observe effects of problem-based learning(PBL) combined with case-based study (CBS)teaching mode in clinical teaching in intensive care unit(ICU). Methods Students from ICU of Fangcun Branch of Guangdong Provincial Hospital of Traditional Chinese Medicine from March 2011 to February 2012 were divided into treatment group (31 cases, with PBL combined with CBS teaching mode) and control group (34 cases, with the traditional teaching mode). Scores of two groups were compared and analyzed and questionnaire survey was conducted in treatment group. Data were processed by SPSS 13.0 statistical software. Measurement data were compared by t-test and data of heterogeneous variance were compared by rank-sum test. Results Treatment group achieved better scores ((85.26 ±5.96) in theory examination and (80.59 ±7.33) in case-analyzing examination) compared with those of control group ((79.17 ±7.31) in theory examination and (76.02 ±9.27) in case-analyzing examination)(P<0.05). PBL combined with CBS teaching mode can stimulate learning interests but it was lack of systematization; most students did not volunteer to speak. Conclusion PBL combined with CBS teaching mode has certain advantages in ICU clinical teaching.

Objective: To explore the clinical effect of Huoxue Qing Gong decoction in the treatment of vaginal bleeding after medical abortion. Methods: From May 2016 to June 2017, 90 cases of vaginal bleeding after drug abortion in the People's Hospital of Dongping County were divided into the observation group and the control group according to the digital table, with 45 cases in each group.The two groups were all treated with drug abortion to terminate pregnancy, and the control group was treated with metronidazole tablets + carbazochrome tablets after the termination of pregnancy.The observation group was treated with Huoxue Qing Gong decoction on the basis of the control group.The effect of abortion, bleeding time and bleeding volume after drug abortion, the time of menstrual recovery and menstrual duration after treatment in the two groups were observed and compared. Results: The total abortion rate in the observation group was 95.6%, which was significantly higher than that in the control group(84.4%), the difference was statistically significant(χ²=5.620, P<0.05). The proportion of bleeding time≤7d after abortion in the observation group was 37.8%, which was significantly higher than that in the control group(11.1%), the difference was statistically significant(χ²=5.628, P<0.05). The proportion of bleeding time 8~14d of the observation group was 60%, which was significantly lower than that of the control group(73.3%), the difference was statistically significant(χ²=6.571, P<0.05). The proportion of bleeding time more than 15d after drug abortion of the observation group was 2.2%, which was significantly lower than that of the control group(15.6%), the difference was statistically significant(χ²=5.028, P<0.05). The proportion of vaginal bleeding volume2=6.021, P<0.05). The proportion of amount of vaginal bleeding=previous menstrual volume after drug abortion in the observation group was 22.2%, which was significantly lower than that in the control group(26.7%), the difference was statistically significant (χ²=5.114, P<0.05). The proportion of vaginal bleeding volume>previous menstrual volume after drug abortion of the observation group was 17.8%, which was significantly lower than that of the control group(44.4%), the difference was statistically significant(χ²=6.375, P<0.05). The period of menstrual recovery of the observation group was (29.5±4.2)d, which was significantly shorter than that of the control group[(37.9±4.3)d](t=5.028, P<0.05). The duration of menstruation in the observation group was (5.0±1.1)d, which was significantly shorter than that in the control group[(6.9±1.2)d], the difference was statistically significant(t=3.229, P<0.05). Conclusion Huoxue Qing Gong decoction in the treatment of vaginal bleeding after drug abortion can significantly shorten the time of vaginal bleeding, reduce the amount of vaginal bleeding, improve the rate of complete abortion, and has no obvious effect on the first menstrual cycle and menstrual period after the drug flow.

Objective To explore the safety, efficacy and 1-year follow-up outcome of radiofrequency ablation combined with magnetic navigation assistance system in elderly patients with atrioventricular node reentrant tachycardia (AVNRT). Methods Forty cases of patients with AVNRT identified by the electrophysiological test were enrolled in the study. Twenty cases were ablated with magnetic navigation system. The other 20 cases underwent the conventional catheters operation. With the cardiodrive, the 8 Frablation magnetic Helios I (Stereotaxis Inc, USA) was advanced to the Koch triangle area from the inferior caval vein (IVC). With the assistance of magnetic navigation (AXIOM Artis, Siemens, Germany), the direction of tip and the advancement or retraction of the catheters were regulated. The success rate, the time of procedure, the fluoroscopy time and the 1-year follow-up outcome were analyzed, and the complications of procedure were recorded. Results Forty cases with AVNRT underwent radiofrequency ablation successfully. In magnetic navigation group, 19/20 cases underwent magnetic catheter operation. The cases who failed to finish magnetic catheter operation underwent successfully conventional catheter operation. There was no perforation complication and no significant statistic difference in the success rate between two groups. No recurring case was found in the two groups 1 year later. The total of fluoroscopy time in magnetic navigation group was more than that in standard ablation group [(16.4±2.7) min vs. (11.1±1.0)rain, P<0.01], but the decreasing trend of fluoroscopy time in magnetic navigation group was showed. The operator's fluoroscopy time in magnetic navigation group was obviously less than that in standard ablation group [(4.5±0.6) min vs. (11.1±1.0) min, P<0.01]. Conclusions The radiofrequeney ablation combining with magnetic navigation system has the similar safety and efficacy to the conventional ablation in elderly patients with AVNRT, but the operator's fluoroscopy time was significantly decreased.

Objective To observe the seroreversion of serological tests for syphilis in neonates born to mothers with syphilis and to evaluate the influence of antisyphilitic treatment on the time of seroreversion in uninfected neonates.Methods A total of 115 neonates born to mothers with syphilis were recruited in this study,and underwent toluidine red unheated serum test (TRUST),Treponema pallidum particle assay (TPPA)and 19S IgM-TPPA at birth.Follow up was scheduled at 1,3,6,9,12,18 and 24 months of age,and cancelled as soon as both TRUST and TPPA became negative during the 24 months.Both TRUST and TPPA were carried out at each follow-up visit.Kaplan-Meiter survival analysis and Wilcoxon rank-sum test were conducted to assess these data by using SPSS 13.0 software.Results At birth,TPPA was positive in all (100％) of the neonates,TRUST in 97 neonates (84.3％) with the titer ranging from 1 ∶ 1 to 1 ∶ 256,19S IgM-TPPA in 3 neonates who were diagnosed with congenital syphilis (CS).CS was ruled out in the other 112 neonates with negative 19S IgM-TPPA after follow up.Of the 3 neonates with CS,all became negative for TRUST within 12-18 months after birth,2 remained positive for TPPA at 24 months of age,1 remained positive for TPPA at 20 months of age,and all were still followed at the time of this writing.The cumulative seroreversion rate was 82.2％,98.9％ and 100％for TRUST at 0-3,4-6 and 7-9 months of age,respectively in 90 uninfected neonates,3.1％,30.2％,85.4％ and 100％ for TPPA at 0-3,4-6,7-9 and 10-12 months of age,respectively in 96 uninfected neonates.Of 16 neonates who missed some follow-up visits,all turned negative for TRUST and TPPA within 15 months after birth.As far as the TP-seropositive uninfected neonates were concerned,no statistical differences were observed in the seroreversion time of TRUST or TPPA between neonates receiving antisyphilitic treatment and those without antisyphilitic treatment (x2 =0.54,2.41,respectively,both P ＞ 0.05).The seroreversion of TRUST occurred earlier than that of TPPA (Z =10.45,P ＜ 0.01).Conclusions Most uninfected neonates born to syphilitic mothers turn negative for TRUST within 6 months after birth,and for TPPA within 12 months.And the seroreversion of TRUST usually occurs earlier than that of TPPA.Antisyphilitic treatment shows no significant influence on the seroreversion time of TRUST or TPPA in these seropositive uninfected infants.
