Constructing clinical teaching hospital is an effective means on resolving the lack of clinical resource,enhancing the benefit of education and ensuring the clinical quality. In order to exert hospital teaching advantage,the criteria system of evaluation on teaching hospital should be taken. Building the teaching function and awareness of hospital are highly important.

Blood Replenishing Angelica Decoction [Danggui Buxue Tang (DGBXT)]is a wellknown TCM prescription composed of Radix Angelicae Sinensis and Radix Astragali with the actions ofinvigorating "Qi" and enriching blood. Its action to curtail endothelial permeability induced by histaminewas studied. Endothelial cells isolated from the aorta of neonatal calf were cultured on polycarbonate mi-croporus filter membrane to develop a confluent endothelial monolayer. After purfused with either plainHank's balanced salt solution or that containing 5 g/L albumin, the monolayer was treated with 10-4 mol/L histamine for 30 min either with or without preincubation for 60 min with 10-4 g/mL of DGBXT. Fluidfiltration coefficient (Kf), filtration volume (Jv) and osmotic reflective coefficient (σ) of protein were thenmeasured. The findings showed that DGBXT could curtail the lowering of Kf and Jv and elevation of σ in-duced by histamine, indicating that DGBXT could inhibit the action of histamine on endothelial permeabili-ty, but its mechanism of action needs further study.

Objective To study the effect of nerve growth factor(NGF)in survival of super-length random flap.Methods The experiment employed the animal model of random flap in Wistar's rat back,applied 66.7 μg NGF locally in trial group's flap at the first day after operation with auto-control.The survival proportion,skin temperature and survival rate of random flap were observed,and the blood flow,the blood flow velocity,the blood flow volume change of random flap were measured by the laser and photic-conduct fiber means in differ time.Results The survival proportion(7.12±1.54)cm2 and survival rate(92±5)%of random flap of trial group was obviously higher(P＜0.05)than those in control group[(5.23±0.19)cm2,(69±5)%]after pedicle division.The blood flow,the blood flow velocity,the blood flow volume and skin temperature in the midge and at the end of random flap in the trial group were obviously higher than those in control group 1 day after operation(P＜0.05),and the blood flow velocity in the pedicle of random flap in the trial group was increased markedly(P＜0.05).The blood flow volume and skin temperature in the pedicle of random flap in the trial group were higher than those in control group 3 days after operation(P＜0.05).The survival of randomflapinthetrial groupwere very significantly increased than those in control group 7 days after operation(P＜0.01).Conclusion NGF can increase flap's blood flow,blood flow velocity and blood flow volume,enhancing survival of the big-proportioned and super-length random flap.

Exploring a pattern of teaching hospital evaluation to solve the problem of its present teaching hospitals being not enough to meet the needs of undergraduate education in the coming a couple of years due to the adjustment of enrolling system and the increase of student number .Through the evaluation ,the university is intended to attain the goal of promoting the building and development in medical treatment,teaching and research of all kinds of teaching hospitals,and the goal of "promoting the development and improvement through evaluation ,combining the evaluation with development ".

AIM: To observe the effects of sera containing Kang xian ling (a traditional Chinese medicine) on c-Met and its downstream MAPK signal molecules in HK-2 cells treated with transforming growth factor-β_1(TGF-β_1), so as to further explore the effective mechanism of anti-renal fibrosis of the traditional Chinese medicine. METHODS: Rat sera containing herbs were collected after rats were intragastrically administered with the herbs. HK-2 cells activated by TGF-β_1 were incubated with different heat-inactivated sera. The proliferation and expression of MAPK and the phosphorylation of MAPK in HK-2 cells were detected by Alarm blue and immunoblotting. RESULTS: No significant difference of cell proliferation between any two groups was observed. C-Met and the phosphorylation of its downstream molecules were also observed after incubated with different sera. CONCLUSION: The receptor c-Met of hepatocyte growth factor, and the phosphorylation of its downstream MAPK molecules can be regulated by the sera containing Kang xian ling.

Traditional Chinese medicine (TCM) is considered an important complementary therapy with beneficial effects for cancer patients. Elderly patients with non-small-cell lung cancer (NSCLC) are a complex patient group with increasing co-morbidity and shrinking physiological reserve, and may derive substantial benefit from the supportive aspects of TCM. Researchers from Shanghai Longhua Hospital found that qi and yin deficiency is a common syndrome in patients with stage III or IV lung cancer. This project was designed to study the combination of single-agent chemotherapy with TCM methods of benefiting qi and yin in elderly patients with advanced NSCLC.

AIM: To study the effect of Kang Xianling decoction,comprised of dahuang,danshen,taoren,niuxi and danggui,on TGF-?1-Smad pathway in unilateral ureteral obstruction rat model.METHODS: Eighteen male SD rats were divided into 3 groups,sham group,model group and model group treated with Kang Xianling decoction randomly.Renal interstitial fibrosis model was established in rats by unilateral ureteral obstruction(UUO).After treatment for additional 14 d,parameters of hydroxyproline in obstructed kidney from 3 groups were analyzed.Rats were sacrificed and the pathological statuses of their kidneys were checked by HE staining and electron microscopy.Transforming growth factor-?1(TGF-?1) mRNA in kidney tissue was determined by RT-PCR.TGF-?1 receptor Ⅰ(T?RⅠ),TGF-?1 receptorⅡ(T?RⅡ),phosphorylated Smad2 and Smad2 protein were determined by Western blotting.RESULTS: Parameters of hydroxyproline in animals of model group were significantly increased than those in sham operation group(P

OBJECTIVETo investigate the effects of erlong zuoci (ELZC) pills and its disassembled prescriptions (Shudi-huang-Zexie group and Zexie group) on the enzymatic activity and protein expression changes of the key apoptosis molecules in the gentamycin injured hair cells.

METHODThe model of gentamycin induced ototoxicity in mice cochlear primary cultures was copied. Cochlear organotypic cultures of postnatal day 3-5 (P3-P5) mice were treated with gentamycin alone or in combination with ELZC pills, Shudihuang-Zexie group or Zexie group respectively. The enzymatic activity of Caspase-9 and Caspase-3 was determined by means of fluorescence staining in situ. The protein expression of Bcl-2 and Bax in the hair cell area was examined by immunofluorescence in normal and treated specimens.

RESULTAverage optical density analysis indicated that, compared to the normal group, 0.03 mmol x L(-1) gentamycin could significantly activate Caspase-9 and Caspase-3, downregulate the ratio of Bcl-2 and Bax protein expression. Compared to the gentamycin model group, ELZC pills significantly inhibited the enzymatic activity of Caspase-9 and upregulated the ratio of Bcl-2 and Bax protein expression, showing inhibition trend toward the enzymatic activity of Caspase-3. Both Shudihuang-Zexie group and Zexie group could effectively inhibit the enzymatic activity of Caspase-9 and Caspase-3, upregulate the ratio of Bcl-2 and Bax protein expression.

CONCLUSIONELZC pills, Shudihuang-Zexie group and Zexie group can effectively protect hair cells from gentamycin by correcting the abnormal changes of the mitochondrion-dependent signal transduction pathway.
