The authors explained the process of organizing and implementing of the designed experiments.The designed experi- ments can improve students' creative thinking ability and activate students'initiative and meanwhile,it can improve teachers' level and contribute to making progress in teaching and studying although there are still some problems to solve.

Taking the genome DNA of Infectious Bovine Rhinotracheitis Virus (IBRV) as the template, the gG gene was amplified with PCR and cloned into the T cloning vector pMD18-T. After being identified by restriction digestion and DNA sequencing, the insert was subcloned into the expression vector pGEX-KG. Sodium docecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and Western blot assay showed that this gene was expressed as both soluble form and inclusion body by the transformed E. coli BL21 strain (DE3). The fusion protein was purified and used as the coating antigen to develop the indirect Enzyme-Linked Immunosorbent Assay (ELISA). Comparison between this gG-ELISA and commercial IBRV gB-ELISA Kit (IDEXX) was made in the detection of 380 cow serum samples. The results demonstrated an agreement of 92%. By using this novel gG-ELISA, 1248 cow serum samples were tested and the average positive rate of IBRV antibodies for imported cows is 21.7%, while the positive rate ranged greatly from 0.0%-41.5% for Hubei local Chinese Black and White Dairy Cows.

OBJECTIVEThe traditional gracilis musculocutaneous flap is supplied by a branch of deep femoral artery, which enters the muscle in between the upper and middle third of it. So the flap barely reaches the pelvis and perineum region for reconstruction. By exploring the blood supply pattern we tried to rotate the flap Upon at the higher point starting at the obturator foramen in order to let it cover a bigger area.

METHODSanatomical reviewing of the blood supply of the gracilis branches of obturator, medial femoral circumflex and deep femoral arteries. Based on this a new type of longitudinal gracilis musculocutaneous flap supported only by the obturator artery was designed to reach the pelvis, female genitalia, pubic symphysis, inguinal area easily.

RESULTSThe new kind of flap has been applied to 9 patients for deformity repairing and tissue replacement in the pelvic and perineal area. All the flaps survived and achieved satisfactory result with 3 months to 3 years' follow up.

CONCLUSIONSLongitudinal gracilis musculocutaneous flaps supplied by the obturator artery can be used as regular musculocutaneous flap clinically.

OBJECTIVETo evaluate the relationship between leukotriene expression in blood polymorphonuclear leukocytes (PMNL) and the efficacy of inhaled corticosteroids (ICS) in children with asthma.

METHODSThirty-two children with asthma (5-12 years) and ten healthy children (control group) were enrolled. The asthmatic children were subdivided into ICS well-controlled and ICS poorly-controlled groups based on their clinical symptoms and lung function. The level of leukotriene C4 synthase (LTC4S) mRNA in PMNL was detected by fluorescence quantitative polymerase chain reaction. The level of LTC4S mRNA was expressed by the value of qCt, and the value of qCt was diversely correlated with the level of LTC4S mRNA expression. The concentration of urinary leukotriene E4 (LTE4) was measured using ELISA.

RESULTSThe expression of LTC4S mRNA in PMNL was significantly higher in children with asthma (qCt: 1.12+/-0.27) than that in the control group (qCt: 1.42+/-0.12; P< 0.05). The expression of LTC4S mRNA in PMNL in the ICS poorly-controlled group (qCt: 1.03+/-0.17) was significantly higher than that in the ICS well-controlled group (qCt: 1.24+/-0.33; P< 0.05) and the control group(1.42+/-0.12; P< 0.01). There was no significant difference in the level of urinary LTE4 among the the ICS poorly-controlled, the ICS well-controlled and the control groups.

CONCLUSIONSLTC4S mRNA expression in PMNL in asthmatic children increases, and the LTC4S mRNA expression in the ICS poorly-controlled group is higher than that in the ICS well-controlled group. This suggests that an increased leukotriene expression might be associated with poorly-controlled asthma.

OBJECTIVETo describe the prevalence of injury associated health risk factors, especially traffic accident/suicide-associated health risk factors in different populations by education, occupation and districts.

METHODSThe indicators on traffic peccancy behavior and protective measures, storage of pesticide and micecide were calculated based on results from 13 questions of BRFS questionnaire by weight on age structures from 2000 census.

RESULTS36.7% pedestrians reported that they had traffic peccancy behavior in the past 30 days with 3.67% as always, 11.3% as sometimes and 21.7% as seldom. 30.3% bicycle riders reported that they had traffic peccancy behavior in the past 30 days. There were 13.2%, 11.4% and 16.9% auto-drivers reported ever having drunken driving, tired driving or driving without license. 7.7% drivers and riders always wore a safety belt. 19.1% motorcycle drivers and riders reported that they wore a crash helmet while riding. The traffic peccancy behavior in males, in rural area was more serious than in females and in urban areas. There were more families preserving pesticide and micecide in rural than in urban areas. 10% of these families did not have a good storage.

CONCLUSIONThe traffic peccancy behavior was very serious, but the protective measures were not well conducted in China. The storage of pesticide and micecide was unsatifactory. The awareness on safety was insufficient in the general population, suggesting that it is of urgent importance to change people's improper behaviors through health education. It is also important to develop regulations to create supportive environment in reducing the deaths caused by injury.
