To construct a recombinant adenovirus containing CDglyES fusion gene, which can directly inhibit human ovarian cancer cell and indirectly inhibit vascular endothelial cell growth. Methods:We constructed prAdCDglyES using a homolo-gous recombination method in bacteria. The prAdCDglyES was transfected to 293 packaging cells using liposome, in which rAdCDgly-ES was packaged and amplified. MTT was used to observe the proliferation inhibition effect of rAdCDglyES on human ovarian cancer cells and the growth inhibition effect of expressing products of rAdCDglyES on ECV-304. Results:The titer of rAdCDglyES was 1 × 1013.3 TCID50/L, whereas the inhibition rate on human ovarian cancer cell SKOV-3 was (83.1±6.3)%. This result is significantly different from the control rAd-LacZ, which had an inhibition rate of (24.1 ± 13.2)% (P<0.01). The concentrated culture supernatant from cells transfected with rAdCDglyES can inhibit ECV-304 cell proliferation at a rate of (78.7 ± 1.6)%. This rate is significantly different com-pared with that of the control with the same concentration of culture supernatant from cells transfected with rAd-CD, with an effect on ECV-304 cell shown by an inhibition rate of (23.9 ± 9.7)%(P<0.01). Conclusion:The results showed that the recombinant adenovirus rAdCDglyES could inhibit human ovarian cancer cells directly and indirectly.

To study the application of simulated-patient teaching in practice teaching and assessment of obstetrics and gynecology,the two groups of students were taught by simulated-patient teaching and discussed cases teaching respectively,and then they were assessed by using simulated patients for clinical skills.The result shows that simulated-patient teaching is effective in improving students' clinical skills,can act as a worthy tool of clinical teaching and assessment.

Objective To investigate the change of serum homocysteine (Hcy) and plasma fibrinogen (Fg) levels in patients with ischemic cerebrovascular diseases (ICVD) and the correlation between Hcy and Fg.Methods Blood samples were collected from 74 patients with ICVD and 40 controls. The concentrations of Hcy, folate and Fg were determinated by means of fluorescence polarization immunoassay, electrochemiluminescence, and immunoturbidimetry, respectively. In the meantime, plasma lipid was detected by routine method.Results Both Hcy and Fg levels in the patients with ICVD increased significantly as compared with the controls (all P0.05). Multivariate logistic regression analysis indicated that hypertension, high cholesterol, high Fg and high Hcy concentrations played significiant roles in ICVD.Conclusion Both hyperhomocysteinemia and hyperfibrinogenemia are independent risk factors of ICVD.

ObjectiveTo develop the classification and coding of medical science data so as to merge and manage the data effectively.MethodsClassification frame was developed with linear classification, coding with matching design.ResultsThe medical science data classification frame, the contents of the frame and their code have been developed. ConclusionThe development of the classification and coding can merge and organize the medical science data effectively.

OBJECTIVETo investigate the effects of epigallocatechin gallate (EGCG)against exercise-induced fatigue in mice.

METHODSTotal 120 mice were randomly divided into three groups and tested separately. For each test, there were 30 mice subdivided into high dose (50 mg/kg . d EGCG) and low dose (10 mg/kg . d EGCG) groups as well as saline control group(1 ml/kg . d) with 10 in each. Burden swimming, running wheel endurance, stick climbing and hypoxia tolerance exercise were used to establish fatigue mice training model in three groups. And intraperitoneal injection with different doses of EGCG per day for consecutively 28 days and the mice in the control group were treated with normal saline. After the last each test, the blood lactic acid (BLA), blood urea nitrogen (BUN), blood lactate dehydrogenase (LDH), muscle glycogen (MG) and liver glycogen (LG) of each group of mice were determined.

RESULTSEGCG treatment groups(B and C)revealed a prolonged the mice survival time of burden swimming test, hypoxia tolerance, running wheel time and the ability of stick climbing(P < 0.05 or P <0.01), and increased LDH activity and MG and LG contents, reduced contents of BLA and BUN. High dose group had an obviously increase effect than lower dose group(P <0.05).

CONCLUSIONEGCG has significant effects against exercise-induced fatigue in mice.

The ratio of plasma aldosterone concentration to plasma renin activity (ARR) is a practical parameter in screening for primary aldosteronism (PA).However,variations of the cutoff value of ARR in different studies have been reported due to plenty of influential factors that may affect the secretions of renin and aldosterone. Lack of standardization of assays for ARR also makes direct comparisons among different studies difficult.The associated influential factors on ARR were introduced in this review.

Objective To explore the clinical effects of enema combined with massage therapy on jaundice in premature infants.Methods Seventy-five premature infants with jaundice were randomly divided into 3 groups,enema combined message therapy group(group A),abdominal massage therapy group(group B),and double-side phototherapy group(group C).All 3 groups were received the same formula fee-ding,intravenous nutrition and identical drug treatment.Group A was given enema with mixed kaiselu and normal saline together with 60 times clockwise abdominal massage once a day for 2 weeks.Group B only received abdominal massage twice per day for 2 weeks.Transcutaneous bilirubin(TB) indexes of all the premature infants in the 3 groups were detected and transformed into total TB concentrations every morning,through version of MINOLTA JM-102 transcutaneous bilirubin radiometer made in Japan.When TB index counted more than 196.58 ?mol/L,group A and B were given single-side phototherapy for 24 hours.Neither enema nor abdominal massage was given to group C,and double-side phototherapy was applied when TB indexes were above 196.58 ?mol/L.Daily TB indexes,duration of jaundice and phototherapy,time of meconium exhaustion,defecation times in each day,incidence of constipation and feeding intolerance were recorded.Results Duration of jaunhospitalized and phototherapy were significantly shortened in group A compared with those of the other groups.In 34 premature infants who were hospital for at least 2 weeks,TB indexes in group C were lower than those in group B on the 9th day.On the 12th day and the 14th day,TB indexes in group A and C were lower than those in group B(Pa
