Objective To study the effects of neferine on the expression of glutathione S-transferase-pi in vitro and to explore the multi-drug resistance reversing mechanism of neferine.Methods 50% inhibition concentration(IC_(50)) of ADM on K562/A02 was determined by MTT method.The transcription of GST-? gene was detected by semi-quantitative RT-PCR and the expression level of GST-? was determined by Western blot after neferine treatment.Results Neferine remarkably enhanced chemosensitivity to ADM of K562/A02 cells.After neferine treatment in day 1,day 3 and day 5,the relative efficiency of K562/A02 to ADM was 9.6%,41.4% and 10.7%,respectively.Semi-quantitative RT-PCR showed that mRNA transcription of GST-? gene was significantly reduced(P

Objective To evaluate the expression of Srvivin mRNA in the occurrence and progress of prostate cancer.Methods The inhibitor of apoptosis gene Survivin mRNA in 45 prostate cancer cases and 30 benign prostatic hyperplasia(BPH) cases were detected by hybridization in situ technique.Results The average optical density of prostate cancer groups(0.4232±0.0085)was signifi cantly higher than BPH groups (0.3303±0.0834) (P=0.001 ).Among the different pathological grades [G1(0.3401±0.0474), G2 (0.4270±0.0074), G3 (0.4560±0.0883)],the difference was statistically significant in the expression of Survivin mRNA (P= 0.004).It was found that there was positive correlation between the transfer of lymph (0.4557±0.7921)and the expression of Survivin mRNA in prostate cancer(P=0.005 ).Conclusion Survivin mRNA is overexpression in prostate cancer.It presumed that Survivin participate in genesis,development of prostate cancer and closely correlated with prognosis.

The present article,based on the resource sharing,integration of personnel and the possible conflict after integration,puts forward the Scientific construction and standardized administration of centralized laboratory center.

Objective To observe the efficacy of the sublingual immunotherapy in children with perennial allergic rhinitis caused by mites .Methods A total of 61 pediatric patients with perennial allergic rhinitis caused by mite in otorhinolaryngology clinic were collected .The children were randomized into two groups :27 cases were divided into sublingual dust mite drops group(group A) , and 34 cases were divided into conventional treatment group (group B) .The symptom scores and sign scores of allergic rhinitis were observed after 6 months ,1 year and 2 years of treatment .Both the efficacy at the end of treatment and the rate of recurrence following 2 years were compared between the two groups .Results After six month of treatment ,the symptom scores in group A was reduced to (3 .70 ± 1 .54)scores ,higher than group B(2 .82 ± 1 .40)scores ,while sign scores in group A was reduced to (1 .19 ± 0 .68)scores ,having no statistically significance compared with group B ,Both symptom scores and sign scores were not changed sig-nificantly after 1 and 2 years of treatment .The efficacy evaluation was 74 .07% in group A ,and 82 .35% in group B .The difference had no statistical difference .The recurrence rate in group A was 29 .63% following 2 years after terminal treatment ,and was superi-or to those in group B (94 .12% ) ,with significant difference(P<0 .01) .Conclusion Dust mite drops sublingual immunotherapy is effective measures for the treatment of children with allergic rhinitis caused by mites .

Objective To investigate the clinicopathologic features and the expression of p53,PCNA and Bcl-2in tricholemmal carcinoma.Methods Skin lesions were studied with HE staining and immunohis-tochemical markers for p53,PCNA and Bcl-2(S-P method)in22cases of skin tricholemmal carcinoma.Both morphological manifestations and immunohistochemical expression were observed.Results There were15fe-male and7male cases of tricholemmal carcinoma with the ages of40-79y,including16cases whose scalp were involved.Positive staining of p53,PCNA and Bcl-2was found in72%,100%and63%of patients,re-spectively.The positive cells of p53were diffusely distributed.PCNA-positive cells were increased along with the degree of differentiation.Significant differences of Bcl-2expression were found among the various degrees of differentiation(P

GATA3 transcription factor plays an important role in the growth and differentiation of normal breast tissues, and it is also closely related to the tumorigenesis of breast cancer. The roles of GATA3 vary in different breast cancer subtypes. This paper reviews the relationship of GATA3 with normal breast tissue and the tumorigenesis of breast cancer, in an attempt to provide theoretical evidences for future clinical applications of GATA3 in breast cancer.

Objective To explore the effectiveness of ω-3 fatty acids in intervening rat models of chronic obstructive pulmonery disease (COPD).Methods The rat COPD models were established by cigarette smoking and intratracheal lipopolysaccharide instillation.Totally 90 rats were randomly divided into 3 groups:normal control group (treated with normal saline),COPD group,and intervention group (the COPD rat models treated with ω-3 fatty acids).Lung tissues were obtained on the 7th,21st,and 28th day.The left lower lobes were analyzed to determine the expressions of nuclear factor-kappa beta (NF-κB) and interferon-γ (IFN-γ)and the right lung lobes were sliced for detecting the cell apoptosis.Double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) was used to detect the serum IFN-γ and interleukin-6 (IL-6).Results (1) The pathological changes of lung tissue:there were a large number of inflammatory exudation,alveolar wall thickening,hyperplasia of vascular smooth muscle and the alveolar structure destruction in the COPD model group,but the lung tissue were part of alveolar cavity and a little inflammatory exudate in ω-3 fatty fish acids treatment group,control rats were almost no alveolar inflammation on the 28th days.(2) On the 28th day,NF-κB protein expression of the lung tissue (18.91 ± 3.07) in rats of COPD model group was significantly higher than the control group and the intervention group (5.47 ±4.86 and 7.23 ±2.21) (P ＜0.01).On the 28th day,IFN-γ protein expression in lung tissue of the rats in the model group was 7.12 ±3.37,significantly lower than the intervention group (18.74 ± 2.65),the difference was statistically significant (P ＜ 0.01).(3) The IL-6 levels of the blood-serum of model group rats were (13.43 ± 2.47) ng/L,significantly higher than the control group and the intervention group [(4.78 ± 1.93) and (4.98 ± 1.89) ng/L],the differences were statistically significant (P ＜ 0.01) on the 28th day,,but the IFN-γ level [(2.23 ± 0.63) ng/L] in COPD group was more poorer than ω-3 fatty acids group and the intervention group [(4.51 ± 0.71) and (7.05 ± 0.52) ng/L] (P ＜ 0.01).Conclusions The ω-3 fatty acids can lower NF-κB protein expressions in lung tissues and serum and IL-6 levels in COPD rats; aslo,it can increase the IFN-γ protein expression in lung tissue and serum.Thus,it can prevent the lung inflammation in COPD rats.
