Objective: To investigate the roles of Bcl-xl and Bcl-xs in the development and progression of endometrial carcinoma, and to explore their correlation.Methods: The expression of Bcl-xl and Bcl-xs in 32 cases of endometrial carci-noma, 12 cases of endometrial atypical hyperplasia, 6 cases of endometrial simple hyperplasia and 10 cases of normal en-dometrial tissues were examined by RT-PCR and Western-blot.Results: The expression of Bcl-xl mRNA and protein was significantly higher in endometrial cancer tissues than in normal endometrial tissues (P<0.05), and was statistically associat-ed with the pathological stage of endometrial carcinoma.(F=5.33, P=0.02).The expression of Bcl-xs mRNA and protein in atypical endometrial hyperplasia and endometrial carcinoma tissues were significantlly lower than that in normal endometri-al tissues (P<0.05), which was also associated with clinical stage and lymph node metastasis of endometrial carcinoma (P<0.05).The expression of Bcl-xl was negatively correlated with the expression of Bcl-xs in different endometrial tissues (r=-0.76).Conclusion: The abnormal expression of Bcl-xs and Bcl-xl was a factor for the pathogenesis and development of endometrial carcinoma.The negative correlation between Bcl-xl and Bcl-xs in different endometrial tissues as well as their relative expression ratio may have certain impact on the genesis of endornetrial cancer.

Results:There was no significant difference in blood glucose indexes between the two groups at baseline ( P>0.05); FBG, HbA1c and other indicators in the two groups were improved during operation and 24h after operation, but FBG (7.38±0.54) mmol/L, HbA1c (6.39±0.21)% and FBG (6.90±0.52) mmol/L and HbA1c (6.10±0.39)% in the study group were lower than those in the control group [(8.16±1.21) mmol/L, (7.53±1.05)%, (7.60±0.57) mmol/L, (6.50±0.41)%], the difference was statistically significant ( t value was 6.789-13.264, P < 0.05); there was no significant difference in SAS and SDS scores between the two groups at baseline ( P > 0.05), until discharge, the SAS and SDS scores of the treatment group were 35.81±5.49 and 42.08±4.91 respectively, which were significantly lower than those of the control group (42.21±5.53, 6.51±4.72) respectively, compared with the corresponding scale scores of the control group, the difference between the two groups after treatment was statistically significant ( t value was 5.386, 4.265, P < 0.05). Compared with 17.31% (9/52) of the control group, the incidence of complications in the study group decreased to 5.66% (3/53), there was significant difference ( χ2 value was 6.789, P < 0.05). The qualified rate of disease knowledge mastery in the study group (98.11%,52/53) was significantly higher than that in the control group (86.53%, 45/52), and the difference was significant ( χ2 value was 5.062, P < 0.05).

Objective To study the effect of continuous subcutaneous insulin injection(CSII) in treatment of type two diabetic patients with pulmonary infections. Methods From January 2001 to December 2005,83 type two diabetic patients with pulmonary infections were randomized to group CSII (42 cases) and group MSII(41 cases). The period of normalization of the blood glucose and cure of the pulmonary infections, cost and morbidity of low blood glucose were observed. Results Blood glucose of all patients in two groups reduced significantly. Significant difference was observed in the period of cure of the pulmonary infections, usage amount of insulin and morbidity of low blood glucose. In group CSII HbA1c, CRP and CHOL reduced significantly. Fasting CRP and high density lipoprotein-C (HDL-C) were remarkably increased. Conclusions Consecutive subcutaneous insulin pump injection is able to control the blood glucose better, to correct metabolic disorder, reduce the cost and hospital day and decrease the morbidity of low blood glucose. CSII is a better of method.

To understand epidemiological characteristics of Marek's disease virus (MDV) prevalent in china currently,3 Marek's disease (MD) strains were isolated and identified from white feather meat chickens vaccined with MDV CVI988 or 814 through necropsy,histopathological observation,virus isolation and IFA detection,named SDAU1501,SDAU1502 and SDAU1503,respectively.vIL8,pp38,MEQ gene of the three strains of MDV were amplified using PCR,and compared with reference strains.The homology between SDAU1501 and SDAU1502 and virulent strains was above 97％,suggesting some features of virulent strains;while meq gene of SDAU1503 lost P amino acid at the 194 th site as that in CVI988,But the distinctive 177 nucleotide insertion mutations was not existed,predicting that it may be a attenuated vaccine strain.New variations of MDV continued and different types of variants emerged,therefore,prevalence and genetic monitoring of MD should be proceeded;meanwhile,more attentions should be given to MDV vaccine development.

Objective To investigate the therapeutic effect of L-carnitine combined with erythropoietin (EPO) and iron on renal anemia in rats. Methods The renal anemia rat model was established using adenine. All rats were randomly divided into three groups: control group (group A), EPO combined with iron group (group B), and L-carnitine combined with EPO and iron treatment group (group C). The levels of red blood cells (RBC), hemoglobin (Hgb), hematocrit (Hct), C-reactive protein (CRP), Fe in peripheral blood (Fe), serum ferritin (SF) and transferrin saturation (TS) were measured. Pathological changes in the kidney, liver and small intestine tissues were examined using HE staining. Results Compared with the group A, the levels of RBC, Hgb, Hct, Fe, SF, and TS were significantly increased, however, the level of CRP significantly decreased in the groups B and C (P＜ 0. 05). In the group C, the levels of RBC, Hgb, and CRP was higher than the group B (P＜ 0. 05). Furthermore, the pathological changes in the kidney, liver and small intestine tissues were improved in the groups B and C. Conclusions L-carnitine combined with EPO and iron has a therapeutic effect on renal anemia in rats, thus, it deserves further studies and application.

Hippo signaling pathway plays an important role in the growth and regeneration of animal organs. Studies have shown that the misexpression of Hippo signaling pathway composed of yes-associated protein and trascriptional co-activator with PDZ-binding motif is involved in the development of non-small cell lung cancer(NSCLC)and has synergistic effect with mutant p53. In addition,its overexpression leads to drug resistance in lung cancer treatment and inhibition of its expression may benefit cancer patients. The expression and role of Hippo signaling pathway in NSCLC are described in detail,which is expected to provide a new direction for targeted therapy of lung cancer.
