Objective To investigate the expression of neurotrophic tyresine kinase receptor TrkB in the eutopic and ectopic endometium of women with endometriosis and evaluate the role of TrkB in the pathogenesis of endometriosis. Methods Seventeen women with endometriosis and 9 controls were studied. Expression of TrkB was investigated using RT-PCR, immunohistochemistry and Western blot, respectively. Results TrkB mRNA was expressed in eutopic endometrium in secretory phase and ectopic endometium of women with endometriosis, (23.51±0.51)% vs (35.29±0.67) % (P<0.05), but TrkB mRNA expression was not detected in control endometrium and eutopic endometrium in proliferative stage of women with endometriosis by RT-PCR. TrkB was expressed both on membrane (glycosylated receptor) and in cytoplasm (non-glycosylated receptor) of the glandular epithelial cells of ectopic endometium, and more often observed in cytoplasm of glandular epithelial cells of eutopic endometrium in secretory phase of women with endometriosis by IHC. In eutopic endometrium in secretory phase and ectopic endometium of women with endometriosis, the expression of TrkB protein was (0.12±0.02)% vs (0.37±0.01)% (P<0.05) by Western blot. Conclusions There is an overexpression of TrkB in eutopic endometrium in secretory phase and ectopic endometium of women with endometriosis. Full-length (glycosylated receptor) TrkB more often is overexpressed in ectopic endometium of women with endometriosis, and TrkB may act as a pathogenic role in formation of endometriosis.

This study was designed to investigate the relationship between the hepatotoxicity of Halothane and altered hepatic calcium homeostasis in enzyme-induced hypoxic rats by means of Ca2+ cytochemistry location and EDX microanalysis combined with micropathological stereology of liver and ultrastructural analysis by computer. The results showed that more calcium precipitated the cytoplasm and mitochondria of liver following Halothane exposure than the controls. Based on the experiments, this alteration appeared to be contributed to the accelerated uptake of Ca2+ by the hepatocytes and lessened to pump out the decreased loaded Ca2+ on the other hand. The release of the reserved Ca2+ was increased by Halothane as compared with controls. These results suggest that a loss of regulation of cellular Ca2+ levels plays an important role in the mechanism of hepatotoxicity by Halothane exposure.

BACKGROUND: Type Ⅰ collagen is a specific collagen secreted by in vitro cultured osteoblast, and the formed network is the basis of bone mineralization, which also reflects the ability of osteoblast bone formation. Studies have shown astragalus root increased osteoblast proliferation. However, the effect of astragalus root on improving type Ⅰ collagen expression of osteoblast remains poorly understood.OBJECTIVE: To evaluate the effect of astragalus root injection on the abilities of rat cranium-derived osteoblast proliferation and type Ⅰ collagen expression.METHODS: Rat osteoblast was cultured in vitro and divided into control group (MEM culture solution containing calf serum) and astragalus root groups (different concentrations). The effect on osteoblast proliferation was evaluated on days 1, 3, 5, 7, and 9 by MTT method. Moreover, the expression of type Ⅰ collagen protein was observed after 6 hours of treatment with astragalus root injection using in cell western-blot method. In addition, the gene expression of COLLal was investigated by real-time PCR method.RESULTS AND CONCLUSION: From days 3 to 9, the different concentrations of astragalus root injection improved osteoblast proliferation, respectively compared with control group (P ＜ 0.05), and this ascending trend peaked on day 7. Different concentretions of astragalus root injection improved COLLol mRNA expression, especially 15% astragalus root injection was the most effective. The type Ⅰ collagen protein expression of 15% and 10% astragalus root injection were significantly greater compared with the control group (P ＜ 0.05). Astragalus root injection improved in vitro cultured osteoblast proliferation and type Ⅰ collagen secretion in a certain dose-effect manner.

Objective To observe the effects of different dosages of granulocyte-macrophage colony-stimulating factor (GM-CSF) on generating the routine bone marrow dendritic cells, and supply suitable dosage of GM-CSF on preparation of dendritic cell vaccines used for different purpose. Methods Using low (5 ng/ml) and conventional (20 ng/ml) and high dosage( 50 ng/ml ) of GM-CSF combined interleukin-4 ( IL-4 ) to induce murine bone marrow dendritic cells were performed, The phenotypes (CD_(11c), CD_(80), CD_(86)) and functional properties of the DC were compared by FACS analysis and MLR. Results The DC induced by low dosage of GM-CSF were immature DC, expressing low CD_(11c), CD_(80), and CD_(86). DC induced by conventional dosage were functional mature, expressing higher CD_(11c), CD_(80), CD_(86), which could induce allogeneic T lymphocyte responses. DC induced by the high dosage GM-CSF were the most phetotypicaUy and functional mature cells, expressing the highest CD_(11c), CD_(80) CD_(86), which could induce the strongest allogeneic T lymphocyte responses. Conclusion The dosages of GM-CSF affect the maturation stage of dendritic cells. Low dosage of GM-CSF generated immature dendritic cells, but conventional dosage and high dosage generated mature dendritic cells. DC generated through high dosage of GM-CSF were the most mature in phenotype and function.

Objective To observe the clinical curative effect of cinobufacini injection in the treatment of primary bronchopulmonary carcinoma.Methods 120 patients with primary bronchopulmonary carcinoma were randomly divided into the control group and treatment group,60 cases in each group.Patients of the control group were treated with the general,symptomatic and dialectical therapy.Patients of the treatment group were given general,symptomatic,dialectical treatment and cinobufacini injection.The curative effect was determined by the standard efficacy of tumor,the survival quality of the patients was judged by the Karnofsky score.The adverse reactions,median survival time and the survival rate were compared between the two groups.Results The effective rate of the control group was 40.0％,that of the treatment group was 56.7％,the difference was statistically significant (x2 =4.034,P ＜ 0.05).By the Karnofsky score,27 patients of the control group were stable,39 patients of the treatment group were stable,the difference was statistically significant(x2 =12.265,P ＜0.05).Median survival time of the control group was (168 ± 16) d,that of the treatment group was (178 ± 20)d,the difference was statistically significant(x2 =12.265,P ＜ 0.05).One year survival rates of the control group and the treatment group were 5.0％,10.0％,the difference was statistically significant.There was no statistically significant difference between two groups in adverse reactions (P ＞ 0.05).Conclusion Cinobufacini injection can improve the quality of life and prolong survival of patients with primary bronchopulmonary carcinoma.It is effective and safe in clinical application.

Measurement of cervical lordosis is the basic method for evaluating cervical function, and important reference for determine treatment decision. However, how to choose appropriate measurement in accordance with different situation, as well as the relationship among these methods is not clear. An increasing number of studies suggested that different measurements could directly affect the judgment of cervical lordosis. Therefore, comparative study of cervical vertebrae plays an important role in clinical treatment for cervical spondylosis under different cervical curvature conditions.

Objective: To observe the changes of heart rate and the contents of angiotensin Ⅱ(AngⅡ) in blood plasma in ventricular tachycardia(VT) rats with electro-acupuncture(EA) on ‘daling’(PC7). Methods: 40 SD rats were randomly divided into normal, model, treatment and control groups with 10 cases in each. VT model was duplicated by inject CsCl in femoral vein. To observe the rats’ electrocardiogram (ECG) and record their heart rates. EA was applied to‘daling’ (PC7) on treatment group and applied to‘Taiyuan’ (LU9) on control group for 5 minutes. Then, we detected the contents of AngⅡ in the rats’blood plasma respectively. Results: The heart rate and contents of AngⅡin rat increased obviously in model group were (547?30) time/min and (353.21?49.12)pg/mL). They restored to the normal state after EA ‘daling’ (PC7) are(474?25)time/min and(268.44?47.49)pg/ mL.But the effect was not obvious in ‘Taiyuan’ (LU9). Conclusion VT rat heart can be prompted to restore to the normal state after EA ‘daling’(PC7); AngⅡ played an important role in VT.

Objective To explore the infiltration and apoptosis of eosinophilia(EOS)and the influence of death receptor(Fas) and B cell lymphoma-2 (Bcl-2) expression after Belamcanda and Ephedra Decoction on asthma rats.Methods40 healthy rats of Holland were selected as the research subjects,they were divided into four groups: control group,asthma model group, dexamethasone group,Belamcanda and Ephedra Decoction group with 10 rats in each group.Rat asthma model was prepared by repeated stimulation of egg protein,the symptoms of asthma in each group were evaluated;the number of EOS infiltration in lung tissue was detected by staining method;EOS apoptosis was detected by methyl thiazolyl tetrazolium(MTT) method;Blot Western was used to detect the expression of Fas and Bcl-2 protein;the flow cytometry was used to detect the apoptosis of EOS in rat.ResultsCompared with the rats in the model group, dexamethasone group, Belamcanda and Ephedra Decoction group rats asthma symptoms were significantly reduced, scores were significantly lower (P< 0.05),there was no significant difference between Dexamethasone group and sheganmahuang Decoction group.In the asthma model group,the number of EOS infiltration and EOS% in venous blood and lung tissue were significantly higher than those in control group,EOS apoptosis rate was significantly lower than that of the control group (P< 0.05).In Dexamethasone group,Belamcanda and Ephedra Decoction group infiltration number of EOS and EOS% were significantly lower than that of model group but higher than the control group, the apoptosis rate of EOS protein was significantly higher than the model group and the control group (P< 0.05),there was no significant difference between Dexamethasone group and sheganmahuang Decoction group.The expression of Fas in dexamethasone group,Belamcanda and Ephedra Decoction group was significantly higher than the control group and model group (P< 0.05),Bcl-2 protein was significantly lower than the control group and model group (P< 0.05),there was no significant difference between Dexamethasone group and sheganmahuang Decoction group.Cell flow cytometry showed that the control group had no cell apoptosis,a large number of apoptotic cells were appeared after Belamcanda and Ephedra Decoction treat with.ConclusionBelamcanda and Ephedra decoction can induce apoptosis of EOS expression,it may be associated with the upregulation of Fas, downregulation of Bcl-2 expression.
