OBJECTIVE: To investigate the effect of propofol on apoptosis in lung tissue of oleic acid-induced acute lung injury(ALI) rats.METHODS: Forty male SD rats were randomly divided into normal control group,ALI group,low,medium and high-dose(4,8,16 mg?kg-1?h-1) propofol groups.Except for the normal control group,the other 4 groups were infused with oleic acid through jugular vein followed by the infusing of the corresponding drugs for 4 h.Then the rats were sacrificed by exsanguination.Lung tissue was immediately sampled for observation of the pathologic change under light microscope and detection of apoptosis and the expression of Fas/FasL,Bax/Bcl-2 in lung tissue by FCM.RESULTS: In ALI group compared with the normal control group,the apoptosis rates in lung tissue cells was markedly increased(P

Objective To study the antihypertensive effects and treatment compliance of extended release nifedipine tablets and nifedipine controlled release tablets .Methods 120 cases of patients with hypertension from April 2012 to April 2013,with informed consent of patients and in accordance with the medical ethics standard ,were divided into the group I and group II of 60 cases in each group according to the random number table method , the group I was given extended release nifedipine tablets for treatment while the group II was given nifedipine controlled release tablets for therapy ,antihypertensive effect ,treatment compliance and adverse reaction of two groups were com-pared.Results The total efficiency of group II was 93.3%,which was higher than 80.0%of the group I,there was statistically significant differences between the two groups (χ2 =12.019,P=0.019);The adverse reaction rate of group II was 8.3%,which was significantly lower than 18.3%of the group I,there was statistically significant differ-ences between the two groups (χ2 =11.271,P=0.021);The treatment compliance of group II was 96.7%,which of the group I was 95.0%,there was no significant differences between the two groups (χ2 =5.419,P =0.067). Conclusion Nifedipine controlled release tablets has a better antihypertensive effect ,with less adverse reaction when compared with nifedipine controlled release tablets .

A 3-year-old boy presented with a 3-month history of brown-yellow papules scattered on the trunk.The first skin biopsy showed a dermal infiltrate of many mononuclear histiocytes,eosinophilic granulocytes and a small number of lymphocytes.Immunohistochemical examination of the lesions demonstrated positive reactions with anti-CD68,-S100 and-CD1a (partial) antibodies.After the biopsy,the skin lesions gradually turned dark and partially regressed leaving hyperpigmentation,but new lesions continuously appeared.Four months later,a second biopsy was performed,and showed a dermal infiltrate of histiocytes with eosinophilic granulocytes and a few multinucleated giant cells.Immunohistochemistry showed that the histiocytes stained positive for CD68,but negative for S100 and CD1a.Based on the above findings,the patient was diagnosed with juvenile xanthogranuloma.

The paper describes the basis, scope, and contents of the index system for assessing maternity and child care institutions in Beijing. The new system, based on the readjustment, recombination and redistribution of the original index system for assessment, has two newly added elements, viz. financial position analysis and leadership style and organization culture. In order to make a distinction between leaders' responsibilities and an institution's orientations and to reduce behavior abnormality and information bias in the process of assessment, the new system has been divided into two major parts: evaluation of the institution's conditions for survival and capabilities for development, which is jointly decided by internal and external factors, and appraisal of the institution's performance, which is decided mainly by internal factors.

Objective To investigate the role of interleukin-27 (IL-27) in proliferation and differentiation of CD4+ T cells in ankylosing spondylitis(AS).Methods CD4+ T cells were separated from peripheral blood which collected from AS patients and health controls(HCs).Cells proliferation was detected by CCK-8 kit,and cytokines were analyzed by ELISA.Real-time PCR was used to determine the mRNA expression of T-bet and GATA3.Results Serum IL-27 level in patients with AS was obviously higher than that in HCs(P ＜0.01).The proliferation rate of CD4+ T cells and the level of IFN-γin cultured medium in AS were higher than those in HCs group after IL-27 stimulation (P ＜ 0.01).IL-27 could induce T-bet mRNA expression in CD4+ T cells in AS (t =14.3,P ＜ 0.01),but no change was found in GATA3 mRNA expression.Conclusions IL-27 could induce the proliferation of CD4+ T cells and the activation of T-bet pathway in AS.Furthermore,Th1 immune response and related cytokines could be induced by IL-27 in AS.These implicate that IL-27 may play an important role in AS related inflammation.

AIM: To optimize the extraction of folium Artemisia argyi polysaccharides by the use of response surface methodoloy.METHODS : Experiment factors and levels were first selected on the ground of one factor test.Along with the central composite experimental design principles,the response surface methodoloy with three factors and three levels was adopted in search of multiple quadratic linear regression.Response surface and contour were finally chosen as the extraction rate and the response value respectively.RESULTS: The optimum extraction conditions of the polysaccharides from folium Artemisia argyi were concluded as follows : extraction temperature was at 99 ℃,extraction time was 2.3 hours,ratio of 20.CONCLUSION : Under these conditions,the yield of folium Artemisia argyi polysaecarides is up to 3.017%,extraction rate of the predictive best polysaccharides is 3.096%,and the relative error is 2.6%.

OBJECTIVE: To optimize the technology of extracting total flavonoids from Sophora japonica.METHODS: The extracting technology of total flavonoids (from Sophora japonica) was optimized by response surface methodology(RSM) with ethanol concentration,solid-solvent ratio,extracting temperature,extracting time and extracting times as factors and the yield of total flavonoids as index.RESULTS: The optimal parameters were determined as follows: the ethanol concentration was 60%;the solid-solvent ratio was 1∶10;the extracting was conducted for 1 time(90 min) at 90 ℃.CONCLUSION:The optimized extraction technology was simple and stable and which serves as references for industrial large scale production.

Objective To investigate the value of the combined test of five tumor markers for gastric cancer diagnosis.Methods The electrochemical luminescence analyzer was used to measure the serum concentrations of CEA,CA125,CA199,CA724 and AFP in 127 gastric patients and 186 controls,and calculated the sensitivity and specificity.Results The concentrations of CEA (52.9 ±25.5)ng/mL,CA125 (54.2 ±40.6)U /mL,CA199 (42.4 ± 28.8)U /mL,CA724 (9.3 ±6.6)U /mL and AFP (22.6 ±11.4)ng/mL in the gastric cancer group were significantly higher than those in the controls,and the differences were statistically significant (t =6.006,7.118,6.033,6.683, 5.362,all P <0.05 ).The sensitivity in gastric cancer diagnosis with the combined test of five tumor markers (88.2%)was higher than the test of CEA (63.8%),CA125 (59.1%),CA199 (41.7%),CA724 (37.0%)and AFP (46.5%)alone,and the differences were statistically significant (χ2 =20.733,27.754,60.209,71.046, 50.270,all P <0.05).Moreover,the specificity in gastric cancer diagnosis with the combined test of five tumor markers (90.3%)was higher than the test of CA125 (79.3%),while lower than the test of CA724 (97.3%),and the differences were statistically significant (χ2 =9.137,7.832,all P <0.05).Conclusion The combined test of five tumor markers (CEA,CA125,CA199,CA724 and AFP)could increase the rate of gastric cancer diagnosis.
