Objective To evaluate short -term clinical efficacy and adverse effects of brucea javanica oil emulsion(BJOE)combined with TP regimen in treating malignant pleural effusion(MPE)of non -small cell lung cancer(NSCLC)by double -way chemotherapy.Methods Totally 91 patients with MPE of NSCLC diagnosed by pathology were builted into the central venous catheter.The patients were assigned to group A,B and C according to therapies.Group A(21 cases)accepted infusion of BJOE 60mL into thoracic cavity twice a week.Group B(33 cases) accepted TP regime therapy,which included paclitaxel(TAX)intravenous chemotherapy at a dose of 150mg/m2 and cisplatin(DDP)injecting into thoracic cavity at a dose of 60mg +0.9% sodium chloride injection 30mL in first day, the therapy was repeated every 3 weeks.Group C(38 cases)combined the therapies of group A′s and B′s.Clinical efficacy and adverse effects were evaluated after 6 weeks.Results The objective response rate(81.6%)for group C was higher than group A or B(χ2 =8.605,P <0.05),the same result were in CR ratio(55.3%)(χ2 =10.384,P <0.05)and PD ratio(5.3%)(χ2 =8.649,P <0.05).There were no serious adverse effects in the three groups.The occurring rate of white blood cell reduction in group A was lower than those of group B and C,there was statistically significance(χ2 =8.999,P <0.05).Conclusion The efficacy of BJOE combined with TP regimen in treating MPE of NSCLC by double -way chemotherapy is better than that of single chemotherapy or alone intrathoracic treatment, and the adverse effects could be well tolerated.

[Summary] The incidence of diabetes mellitus is increasing year by year ,which attracts more and more attention. Scientific researches have demonstrated the role of chronic systemic inflammation and immune dysregulation in the development of type 2 diabetes mellitus (T2DM ). Moreover ,the evidence of islet autoimmunity has also been identified in some patients with T 2DM. These discoveries highlight the potential of immune‐modulatory therapies for T 2DM.

[Summary] The human thyroid epithelium cells were obtained from normal para-adenoma tissues of patients with thyroid adenoma or nodule.Cells were treated with 1 000 IU/ml interferon-γ (IFN-γ) + 10 ng/ml tumor necrosis factor-α (TNF-α),1 mmol/L N-acetylcysteine (NAC),1 mmol/L glutathione (GSH),and 10 μmol/L dexamethasone (DEX) respectively.Malondialdehyde(MDA),glutathioneperoxidase(GSH-Px),and superoxidedismutase(SOD) levels in the cell supernatant were measured.The results showed that IFN-γ+TNF-α significantly increased MDA level (P＜0.05) while decreased GSH-Px and SOD levels (P＜0.05).After NAC,GSH,and DEX intervention,MDA levels all were significantly lowered (all P＜0.05) while GSH-Px and SOD levels were significantly increased compared with IFN-γ+TNF-α stimulation(all P＜0.05).These results suggest that IFN-γ and TNF-α can induce oxidative stress in the human thyrocyte,and this effect is antagonized by NAC,GSH,and DEX via increasing GSH-Px,SOD activity and decreasing MDA content.

To investigate the protective effects and possible mechanism of Mycelium of Hirsutella hepiali Chen et Shen (MHCS) on metabolic syndromes, free fatty acid and MHCS-treated hepatocytes were used for detecting autophagy-related LC3, p62 and lipid accumulation. Moreover, high fat diet fed mice were used to establish metabolic syndromes model. 50-weeks age mice were randomly divided into: control group, model group and MHCS group. At 80-weeks age, 15 mice were randomly chosen from each group separately for examining oral glucose tolerance, serum insulin, insulin-like growth factor 1 (IGF-1), hepatic LC3, p62, p-NF-kappaB p65, NF-kappaB p65, IL-6 and CXCL-8. Moreover, insulin resistance index (IRI) was calculated. Hepatic pathological changes, including vacuoles, lipids accumulation and fibrosis were observed. Remaining mice were fed with diet separately to 110 weeks-age for statistics of mortality. MHCS promoted autophagy of free fatty acid treated hepatocytes. Mice fed with high fat plus MHCS diet exhibited improved oral glucose tolerance, insulin resistance, hepatic pathology, inflammation, mortality and activated autophagy. The protective effects of MHCS against metabolic syndroms might be through the activation of hepatic autophagy.

Graves′disease ( GD) is an organ-specific、autoimmune and hyperthyroid thyroid disease closely related to the TSH receptor antibody ( TRAb) .Oxygen free radicals and the oxidative damage caused by these are closely related to the development and progression for GD .Researches on oxidative stress are providing novel therapeutic targets of GD .

Objective:To investigate the influence of gender difference on the activation of platelets in septic rats.Methods: Totally 20 female and 20 male SD rats were randomly divided into four groups: male sham-operated group,female sham-operated group,female septic group,and male septic group,with each group containing 10 rats.Sepsis model in the last two groups was produced by cecal ligation and puncture(CLP);rats in the sham-operated group received no CLP.The rats were sacrificed 24 hours after surgery;the blood samples were collected for blood routine test;and the serum ?-TG levels were detected by ELISA assay.Serum estrogen(E2) levels were detected by radioimmunoassay.Results: The blood platelet counts were decreased in both septic rats of both genders;the count in female rats was significantly higher than in the male rats(P

The paper introduced the recent development of optical tweezers array.The particle manipulation system could be set up based on several methods,such as acousto-optics deflectors(AOD),diffractive optical elements(DOE),spatial light modulators(SLM),interference technique,vertical cavity surface emitting laser(VCSEL),optical fibers and micro-lens arrays as well.The principle,specification and basic structure of each method were introduced and analyzed briefly.Taking the advantage of particle trapping,optical tweezers array was very useful for manipulation of micron size particles,such as cells.Combining with microfluidics and MEMs fabrication,optical tweezer array,the ultraminiature and portable particle sorting system,would be a good choice for space biological research.

Fifty cases of acinic cell carcinoma(ACC) of salivary glands were observed in a period of 22 years(l960-1982) in this hospital. 25 tumors out of the 50 occurred in the parotid gland, 7 in the submaxillary gland, and 18 in other minor salivary glands. Conventional microscopy revealed that ACC of salivary glands are composed of granulated acinic cells, clear cells, vacuolated cells, and intercalated duct cells. According to the different histological features, the authors suggest that ACC are to be classified into 6 types: cystic papillary, solid ethmoid, tra-beculopapillary, acinic adenoid, acinic nestlike and diffuse types. This classification facilitates the clinicians and pathologists to grasp the pathological cha- racteristies and diagnostic criteria and assessable prognosis and to accumulate the clinical material for research purposes.Thirty-seven patients out of the 50 have been followed up for years, the longest up to 19 years. 14 patients(37.8%)developed local recurrences. The five and ten year survival rates are 62.2% and 37.8% respectively.The differential diagnosis, histochemistry, histogenesis, and prognosis of ACC were discussed with a brief review of the literature concerned. Our data supports the assumption that ACC originates from the intercalated duct cells rather than from fully differentiated serous cells.

Objective To test the hypothesis that locally direct gene transfer of human vascular endothelial growth factor(phVEGF) 165 could passivate hepatic venous metallic stents by accelerating endothelialization and augmenting biocompatibility of endovascular stent. Methods The complexes of pAdTrackCMV and lipofectamine was smeared homogeneously to the surface of stent coating with poly-1-lysine. Bare stainless steel stents were used as controls. All stents were implanted into the hepatic right vein by the procedure of transjugular intrahepatic venous stent deployment. Results At the end of 1 week after implantation, the site -specific expression of phVEGF was detected by RT-PCR. Green fluorescence and the expression of phVEGF gene were detected in the transfered stented vessel of the treatment group. These phenomena were not observed in the control group. Scanning electron microscopy revealed that the endothelialization of stent was more pronounced in the treatment group than that in control group. At the end of 8 weeks after implantation, quantitative angiography analysis showed the degree of internal diameter stenosis was less severe in the treatment group compared with the control group. Mean neointima thickness, mean neointima areas and percent cross-sectional area narrowing in treatment group was significantly fewer than that in the control group, respectively. Immunohistochemistry analysis revealed that the proliferation of vascular smooth muscle cells was more active in control group than that in the treatment group. Conclusions Local gene transfer of phVEGF165 can passivate endovascular stents by accelerating stents endothelization and enhancing their biocompatibility in hepatic vein, resulting in reducing thrombus formation and attenuating intimal hyperplasia.
