Objective To explore the correlations of expression of Fas, FasL and C-erbB-2, its clinical significance and the correlation prognosis. Methods To protect the expression of mFas, mFasL and C-erbB-2 by immunohistochemistry SP method. To protect the sFas content by ELISA method. Results The expression of Fas showed lowest levels in breast carcinoma, showed lower levels in fibro-adenoma of breast and breast atypical hyperplasia, and showed highest levels in normal controls. The expression of FasL showed adversely, sFas showed highest levels in breast carcinoma, then in breast atypical hyperplasia, and showed lowest levels in normal control group. Fas and C-erbB-2 obviously presented negative correlation. Conclusion The expression of mFas showed inhibition in breast carcinoma, adversely the expression of mFasL showed enhancement, hint abnormality expression of mFas, mFasL may relevant tomammary glands cancer of occurrence and development. It can be used for estimating prognosis, but need a further research.

Objective To observe the effect of Tongbihuoluo Tang on the cerebral infarction.Methods 148cases in recovery of cerebral infarction were randomly divided into control and treated groups(each n =74),the control group was treated with conventional western medicine,while the treated group was treated with Tongbihuoluo Tang based on the conventional treatment,the course was 28d,then the clinical efficacy of the two groups was compared.Results After treatment the neurological deficit score was significantly improved compared with before treatment,the treated group was better than the control group.The efficacy of the treated group was significantly better than the control group,the total effective rate was 94.6％,which was significantly higher than 75.5％ in control group,the difference between the two groups was significant(P ＜0.05).Conclusion Tongbihuoluo Tang may be helpful to the patients on the basis of western medicine,and it was worthy to be used in clinical practice.

Objective To screen out the tetrahydrobiopterin def iciency in patients with hyperphenylalaninemia by urinary pterin analysis. Methods Analysis of urinary neopterin (N) and biopterin (B) was done in 96 patients with hyperphenylalaninemia by high performance liquid chromatography. Combined BH4 loading test was performed for patients with abnormal urinary pterin profiles. Results Eleven patients were diagnosed as ha ving BH4 deficiency caused by 6 pyruvoyl tetrahydrobiopterin synthase deficiency. They had a much high N/B ratio(N/B:197?250) and a very low B percentage (1.0?0.8)%. Blood phenylalanine levels were decreased from (720 1 200) ?mol/L to (120 240) ?mol/L after taking BH4 tablets in 4 of 11 patients. Conclusion The incidence of BH4 deficiency among hyperphenylalaninemia is about 12%. Analysis of urinary pterin is feasible and effective in screening of BH4 deficiency.

Objective To establish a method of quality control for compound Cornu cervi degelatinatum tablets. Methods Thin layer chromatography ( TLC ) was used for qualitative identification of Lonicerae Japonicae Caulis and Pyrola Herba in the preparations. High performance liquid chromatography was used to determine the content of loganin and chiratin in Lonicerae Japonicae Caulis and monotropein in Pyrola Herba. Results The TLC spots were clear and specific in the qualitative identification.HPLC determined the content. In the concentration range, monotropein, loganin and chiratin had a good linear relationship with peak area (r>0.999).The mean recovery was 97.2%, 98.4% and 96.0%;RSD was 1.4%, 0.8% and 0.8%. Conclusion The present study employs TLC for quality control and HPLC for quantity control. The methods are simple and accurate, have good reproducibility, and can effectively control the quality of compound Cornu cervi degelatinatum tablets.

Objective To observe the expression of MMP-1, TNF-a in cholesteatoma and to determine their roles in the destruction of bone and their correlation. Methods Immunohistochemical method and the computer image quantitative analysis were used to examine the expression of TNF-α and MMP-1 in 22 cases of chotesteatomamiddle ear and 20 cases of normal external acoustic meatus skin. Results Positive stainings of MMP-1 and TNF-α were both localized in cytoplasm. The MMP-1 positive cells were found in all strata of cholesteatoma epithelium and active multiplication stromal cell. TNF-α was expressed in both epithlium and stromal cells. The results of the computer image quantitative analysis showed that the mean optical density of MMP-1 (0. 2013±0. 0106) and TNF-α (0.3852±0.0318) in cholesteatoma were higher than that in normal skin epithelial tissue( P＜0.05 ). Conclusion (1)MMP-1 and TNF-α are overexpressed in cholesteatoma. (2)MMP-1 and TNF-α have a correlation in their expression. (3)MMP-1 and TNF-α are both observed in stromal cells which indicates that stromal cells play an irnportant role in bone destruction.

Tumor tissue is a complex of tumor cells, stromal cells, and extracellular matrix, and they constitute a disordered and aggressive microenvironment, which plays an indispensable role in the occurrence and development of tumors. In breast cancer, cancer-associated fibroblasts (CAF) not only promote the occurrence, proliferation, invasion, metastasis, and drug resistance of tumor, but also participate in events including angiogenesis, lymph angiogenesis, extracellular matrix remodeling, and reconstruction of the microenvironment, which are known to induce cancer. Therefore, a new strategy for tumor therapy is provided by targeting CAF. This article reviews the research progress of CAF in breast cancer.

Clinic probation teaching is an important part of medical education practice, whose teaching effect andquality have impact on the quality of cultivation for medical students. To solve the existing problems, Gannan MedicalCollege has combined the single clinic probation with social practice activities, expanded the probation teaching area,made the full use of students' capability, reformed the traditional probation teaching pattern, defined teaching objectivereasonably, which gives rise to the improvement in clinic teaching quality.

Objective To investigate toe-brachial index ( TBI) in the diagnosis of peripheral artery disease ( PAD) and its risk factors in the patients with type 2 diabetes.Methods TBI was examined in the 238 patients with type 2 diabetes.The patients were divided into the group with low TBI ( TBI≤0.7 ) and the group with normal ABI ( TBI>0.7 ) .The two groups were compared for clinical parameters.Results Thirty two patients (13.4%)with abnormal ABI (TBI≤0.7) showed older age [(63.8 ±9.9) yrs vs (54.9 ±10.8) yrs, P =0.000] , lower diastolic blood pressure [(70.5 ±6.9) mmHg vs (74.9 ±9.1) mmHg, P =0.003], more frequency of hypertension (56.3%vs 38.3%, P =0.043), coronary artery heart disease (28.7%vs 10.7%, P =0.020) and cere-bral vascular disease (15.6%vs 4.4%, P =0.025).Step-wise analysis screened that age and diastolic blood pressure were the inde-pendent risk factors for TBI .Conclusions Aging and hypertension were the risk factors in the patients with abnormal TBI in type 2 di-abetes.TBI was an easy and economical method for diagnosing PAD in patients with type 2 diabetes.

Purpose To assess left ventricular diastolic function in the patients with essentialhypertension. Methods 25 normotensives,93 hypertensiives without hypertrophy (NLVH) and 47 withhypertrophy (LVH)(LVMI, left ventricular mass index ＞ 124 g/m2 in males and 110 g/m2 in females)underwent 2DE and Doppler echocardiography. Results The ratio of early to late peak velocity (E/A)was 1.21 ± 0.24 in normotensives and 1.03 ± 0.23 in NLVH patients( P ＜ 0.01 ); reversed pulmonaryvenous flow at atrial systole PA wave was (32.7 ± 7.5 ) vs (38.9 ± 8.7) cm/s (P ＜ 0.01 ) in normotensivesand in NLVH patients respectively. The isovolumic relaxation time (IVRT) and left atrial dimension (LAD)have significant differences in three groups ( P ＜ 0. 05 - 0. 001 ). EF value was similar betweennormotensives and NLVH patients, but it was lower in LVH patients ( P ＜ 0.01 ). Conclusions E/Aratio, PA wawe, Pai, IVRT and LAD are sensitive parameters indicating mild diastolic left ventriculardysfunction. Systolic left ventricular function has no change in NLVH patients.
