To study the protective effect of Shengmai Injection on adriamycin-induced cytotoxity of diaphragm in rabbits. The rabbits were randomly allocated to three groups. The control group were treated with NS 2 ml?kg -1 for five days, adriamycin+NS group with NS 2ml?kg -1 for five days and then administered adriamycin 10 mg?kg -l and adriamycin + Shengmai Injection group with Shengmi Injection 2 ml?kg -l for five days and then administered adriamycin 10 mg?kg -1 . Twenty-four hours later, animals in the three groups were anaesthetized. Then the transdiaphragmatic pressure (Pdi) and diaphragm evoked potential(DEP) were measured, SOD activity and MDA content were tested and the ultrastructure of diaphragm cells was observed under electron microscope. Adriamycin could lower the Pdi and amplitude of DEP (P

Thyroid-stimulating hormone receptor(TSHR)is an important autoantigen whose cleavage and shedding can induce autoimmunity.The TSHR is the main functional receptor of the thyroid.The shedding of the ? subunit plays an important role in the forming of TSAb and balancing between TSAb and TBAb.Research on the cleavage and shedding of the TSHR extracellualar domain helps to gain a deep insight into the structure and function of TSHR,illuminate the pathogenesis of autoimmune thyroid disease and find out a new therapy.The structure of TSHR,the mechanism and the significance of its cleavage and shedding are reviewed in this article.

Objective To discuss the treatment effect of ginseng polysaccharide injection auxiliary GP chemotherapy for patients with non-small cell lung cancer.Methods 130 cases of patients with non-small cell lung cancer from June 2011 to June 2013 were randomly divided into two groups, 65 cases in each group.The control group was given gemcitabine and cisplatin treatment.The observation group were treated with ginseng polysaccharide injection on the basis of the control group.After 3 months of continuous therapy, the therapeutic effect, T-lymphocyte subsets, adverse events, quality of life scores of the two groups were compared, and survival in two groups of patients were also compared after 1 year follow-up.Results The total efficiency and clinical benefit rate in observation group were 58.5%, significantly better than the control group ( 41.5%) , the difference was statistically significant (χ2 =3.72, P<0.05);CD3, CD4 and CD4 /CD8 in observation group were significantly higher than the control group, the differences were statistically significant (t =5.735, 7.885, 7.326, P<0.05), whereas CD8 was significantly lower than the control group, the difference was statistically significant (t=2.442, P<0.05).The main adverse reactions of the two groups of patients during treatment were myelosuppression (WBC and platelet decreasing and anemia ) and gastrointestinal reaction.Score of life quality in observation group was ( 71.5 ±12.9 ) after treatment, significantly higher than the control group (64.2 ±12.2), the difference was statistically significant (t=3.315, P<0.05).1-year survival rate in the observation group were 63.1%, and 52.3% in the control group.Conclusion Ginseng Polysaccharide injection auxiliary GP chemotherapy for non-small cell lung cancer has significantly efficacy, enhances immunity, reduces side effects, better quality of life.

Antiinf lammatory effects of Ferulofen ( FL ) were shown by im or ip on xylene-induced swellingof mice ear, carrageenin produced edema of hind paw in rats, and decreased volume of pleural exud- ate on carrageenin-induced acute pleurisy of rats, FL also inhibi-tied the proliferating granuloma by croton oil. The above dose r-ange in 50-100mg/kg im or ip which presented a good dose-effect relationship, FL also inhibited the mice writhing caused by H AC & tail-flick response to 1 light irradiation, suggesting its strong analgesic effect. In addition, its anticancer effect in vitro ( carcinoma of Ehlrich ascitis)was better than that in vivo ( Sl80 sarcoma) in mouse. So FL may be considered to be a promising new type of non-steroidal antiinflammatory & anticancer drug ,worthy of further reseaching & exploring in the future.

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

Objective To observe the effects of gypenosides(GP) on cardiac dysfunction induced by adriamycin in rats and to investigate the therapeutic mechanism.Methods Adult male Sprague-Dawley rats were randomly divided into 5 groups:control group,adriamycin(ADR) group,low-,moderate-and high-dose GP groups.The low-,moderate-and high-dose GP groups received GP 100,200 and 400 mg? kg-1? d-1 for five days respectively.Meanwhile,the purified water was given to rats of control group and adriamycin groups.On the sixth day,adriamycin(10 mg? kg-1) was given intraperitoneally(ip) to all the groups except the control rats.At the twenty-fourth hour after administration of adriamycin,the cardiac functions such as left ventricular systolic pressure(LVSP),maximal rates of increase and decrease of left ventricular pressure(? dp/dtmax),as well as the activities of cardiac ATPase,succinic dehydrogenase(SDH) and sarcoplasmic reticulum Ca2+-ATPase(SERCA2a) were measured.Results The impairment of heart function induced by adriamycin was relieved and the activities of cardiac ATPase,SDH and SERCA2a were obviously increased after GP treatment.Conclusion GP have protective effects on cardiac dysfunction induced by adriamycin in rats,and the mechanism may be related to the increase of activities of cardiac ATPase,SDH and SERCA2a.

Objective: Effects of Shenmai injection and aminophylline alone or in combination on transdiaphragmatic pressure and electrical activity of diaphragm were observed, so as to evaluate their effecfs on diaphragmatic fatigue. Methods: The diaphramatic fatique (DiF) model was estab- lished by stimulating bilateral phrenic nerves for 40 minutes. The animals were allocated to three groups: Shenmai group (2mL/kg, N=7), aminophylline group (20mg/kg, N=7) and combi- nation group (Shenmai injection 2mL/kg+aminophylline 20mg/kg, N=7) The transdi- aphragmatic pressure (Pdi) and diaphragmatic electromyogram (EMGdi) were recorded before and after treatment. EMGdi was analysed by computer and then the high/low frequency ratio (H/L) and the central frequency (Fc) were caculated. The diaphragm evoked potential (DEP) was record- ed simutaneously. All data was analysed by analysis of variance and q test. Results: Pdi, H/L, Fc and amplitude of DEP were markedly increased after the treatment with aminophyline and Shen- mai injection alone (Compared with DiF. P

Objective Using the soaking seedling method to introduce wild Gastrodia elata DNA into potato plantlets and analyze gastrodin of transformed Solanum tuberosum.Methods After the tuber grown up,the solution of gastrodin was extracted from the potatoes which were transformed by wild G.(elata) DNA.The transformed plants were scaned by ultraviolet.PCR was used to analyze GAFP gene by SDS-PAGE.TLC was used to analyze the gastrodin of transformed S.tuberosum.Results(1)The 21 transformed plants had obvious absorption peak at 220 nm in 200 transformed S.tuberosunr.(2)The fragment of wild G.elata GAFP gene was found by PCR from 5 transformed plants.(3)The protein expressions in transgenic S.tuberosum were obviously different from the normal S.tuberosum;a band was detected in transgenic S.tuberosum and wild G.elata,but wasn't detected in normal S.tuberosum.(4)The expression of the gastrodin was detected by TLC from three transformed plants. Conclusion It is feasible to use the soaking seedling method to introduce exogenous DNA into plants.
