There exists the contradiction between medical value and social ethics on human-body experiments,so the ethics requires that we should set a comprehesive appraise and choose the corresponding ethical principle to standardize the behavior of human-body experiments.

Objective Quantifiably and located measure the methylation rate of 21 cytosinephosphate-guanosine (CpG) sites in the 3' region of L1 gene and long control region (LCR) gene of HPV16 DNA in asymptomatic patients,cervical intraepithelial neoplasia (CIN) patients,and cervical cancer patients.To analysis the relationship between HPV16 methylation and it's pathogenicity.Methods Chosen 30 cases with HPV16 positive in each group.Firstly,extract DNA from the remaining cells of liquid-based cytology specimen and bisulfite treatment DNA,then amplify the 3' region of L1 gene and LCR gene,test the methylation rate of 21 CpG sites of HPV16 DNA in three groups.Results All of the 5 CpG sites in E6/E7 promoter (31,37,43,52,58) were hypomethylation in cervical cancer group (21.86％,28.15％,21.37％,26.15％,15.48％,respectively),hypermethylation in asymptomatic group,and middle-methylation in CIN group,in which there were significant difference among three groups (all P ＜0.01).The CpG site in 7032,7091,7136 of the 3' region of L1 gene was also different methylated among three groups (all P＜0.01).Hypermethylation was found in cancer group (18.89％,27.72％),hypomethylation was found in asymptomatic group (2.71％,6.95％) in 7032 and 7091.In 7136,the highest methylation was detected in CIN (66.45％),the lowest in asymptomatic (34.85％),middle in cancer group (46.43％).Conclusion The methylation status of CpG sites in the 3' region of L1 gene and E6/E7 promoter of HPV16 is significant different among three groups,which is likely to anticipate the pathogenesis of CIN and cervical cancer.

Objective To investigate the dose-response relationship of spinal ropivacaine when it is combined with spinal fentanyl 20 ?g for cesarean section. Methods Sixty ASA Ⅰ-Ⅱ full-term nulliparous women undergoing cesarean section under combined spinal-epidural anesthesia (CSE) were randomized to receive spinal fentanyl 20?g and ropivacaine 10 mg (group A, n = 20) or 13 mg (group B, n = 20) or 15 mg (group C, n = 20) . Spinal puncture was performed at L2-3 interspace. A catheter was inserted 3 cm in the epidural space cephalad. If spinal analgesia was inadequate 2 % lidocaine was given epidurally. The clinical efficacy was rated based on analgesia, muscle relaxation and visceral traction response as Ⅰ-Ⅳ (Ⅰ= worst, Ⅳ= best). The probit log dose-response relationship was determined. The ED50 and ED95 of ropivacaine for spinal anesthesia when combined with spinal fentanyl 20 ?g were calculated. Complications such as hypotension, nausea, vomiting and shivering were recorded. Results The three groups were comparable with respect to age, sex, body weight, height and duration of operation. The clinical efficacy in group B and C was significantly better than that in group A ( P

Objective To explore the clinical features diagnosis and treatment of left main coronary artery (LM) disease. Methods According to the results of coronary angiography,significant stenosis was defined as ≥50% stenosis. Isolated LM group had 9 patients (4.62%),one-vessel stenosis LM group 15 patients (7.69%),two-vessel stenosis LM group 53 patients (27.18%) and three-vessel stenosis LM group 118 patients (60.51%). Results 195 cases (6.74%) of LM stenosis were found. The incidence rate was low. 164 patients (84.1%) had unstable angina,and 125 patients (64.1%) had myocardial infarction. Coronary artery bypass surgery was performed in 57 patients (29.2%) and the angina disappeared in most of them (84.2%). Five patients received unprotected LM stenosis and angina disappeared in all. Conclusion LM stenosis has sever symptoms. Coronary angiography is the only way for diagnosis and CABG the best treatment. Unprotected LM stenosis is valuable for some patients.

Objective To observe the relationship between short-term heart rate variability(HRV) and heart rate recovery (HRR) after exercise.Methods 495 patients (273 men),whose age ranged 19-85 years,were submitted to treadmill exercise tests and short-term HRV evaluations.The standard deviation of the normal-to-normal interval (SDNN),the square root of the mean squared differences of successive normal-to-normal intervals (RMSSD),the number of interval differences of successive normal-to-normal intervals greater than 50 ms (NN50 count),the proportion derived by dividing NN50 count by the total number of normal-to-normal intervals (pNN50) and frequency(lowfrequency power,high-frequency power,total power) domains were observed.Results Among 495 patients,106 patients(68 men) were elderly(age≥65 years).Male gender and hypertension were significantly higher in elderly patients.The young patients had higher HRR after exercise.HRR at 4min (54 ± 13) vs (60 ± 12) beats/min,P =0.003 was the most significant predictor for positive exercise test result.In the young group,both time domain measures (SDNN:correlation coefficient 0.34,P ＜ 0.001 ; RMSSD:correlation coefficient 0.37,P ＜ 0.001) and frequency domain measures (LF:correlation coefficient 0.21,P ＜ 0.001 ; HF:correlation coefficient 0.13,P =0.01 ; total power:correlation coefficient 0.22,P ＜ 0.001) were significantly associated with HRR at 4min.Conclusion HRR at 4min was significantly associated with short-term HRV of time and frequency domains in young individuals,but not elderly ones,who received treadmill exercise test.
