Results ACT score and FEV1 percentage expected index changes of two groups there was no significant difference before the treatment. After treatment, ACT score and FEV1 percentage expected index changes of the study group was better than the control group(P<0.05). Conclusion Salmeterol fluticasone propionate combined with montelukast in the treatment can significantly improve the clinical efficacy of patients.

Objective:To analyze related factors to the informed consent competency of patients with schizophrenia.Methods:Subjects were divided into two groups,namely one group including 100 patients with schizophrenia and the other group including 28 heathy controls.Patients with schizophrenia were administrated from community rehabilitation units and The Sixth Hospital of Peking University,diagnosed with the Diagnostic and Statistical Manual of mental disorder,Fourth Edition (DSM-Ⅳ).Informed consent competency of subjects were evaluated with the Chinese Mandarin Version of MacArthur Competence Assessment Tool for Clinical Research.Psychiatric symptoms,intelligence quotient and severity of disease were accessed individually with the Positive and Negative Symptom Scale (PANSS),Wechsler Abbreviated Scale of Intelligence (WASI) and Clinical General ImpressionSeverity Scale (CGI-S).Logistic regression analysis model was used to analyze the risk factors of impaired informed consent competency in schizophrenia.Retsrts:The rates of absent,impaired and adequate informed consent competency were 26.0％ (26/100),47.0％ (47/100) and 27.0％ (27/100) in schizophrenia group,and 3.6％ (1/28),57.1％ (16/28) and 39.3 ％ (11/28) in control group.Rate of absent informed consent competency was higher in schizophrenia group than that in control group (26.0％ vs.3.6％,P ＜0.01).There were no statistic significant differences in rates of impaired and adequate informed consent competency between two groups (both P ＞ 0.05).Results of logistic regression analysis showed that schizophrenic patients with higher scores of positive subscale (OR =1.15),negative subscale (OR =1.23) and CGI-S (OR =1.57) had more tendency to impaired capacity.Higher education level (OR =0.73) and higher scores of IQ (OR =0.92) had less risks for that.Conclusion:Competency of informed consent in schizophrenia may be worse than that in health control.Patients with schizophrenia with impaired informed consent competency may have more serious of positive,negative psychiatric symptoms and higher severity of disease.Higher level of education and IQ scores may reduce the risk of impaired informed consent competency.

The first imported Middle East respiratory syndrome (MERS) case in China was identified in May 2015. We determined the kinetics of antibody (IgG and IgM) and neutralizing antibodies against MERS-coronavirus (MERS-CoV) in this case before discharge. Moreover, no seroconversion was found among 53 close contacts by anti-MERS IgG antibody enzyme-linked immunosorbent assay (ELISA) of paired serum samples. These findings suggest that neither community nor nosocomial transmission of MERS-CoV occurred in China.

Objective To investigate the relationship between Wnt5a gene and E-cadherin or vimentin gene in breast cancer cell line MCF-7. Methods RT-PCR was used to detect the mRNA expression of Wnt5a, E-cadherin and vimentin in breast cancer MCF-7 cells and the normal human mammary epithelial cell line MCF-10A, respectively, and their correlation was analyzed. Results The mRNA expression levels of Wnt5a and E-cadherin in cell line MCF-7 were significantly lower than those in cell line MCF-10A [(16.93± 2.97)%vs. (27.47±2.76) %, (12.97±1.35) % vs. (20.43±2.60) %, both P<0.05]. The mRNA expression level of vimentin in cell line MCF-7 was significantly higher than that in cell line MCF-10A [(16.53±0.85)%(6.33± 2.08) %, P<0.05 ]. In cell line MCF-7, the expression of Wnt5a was positively related to E-cadherin (г=0.997, P<0.05), but it was negatively related to vimentin (г=-0.998, P<0.05). Conclusions The expression of Wnt5a in human breast cancer cell line MCF-7 is significantly lower than that in cell line MCF-10A, which indicates that Wnt5a is a cancer suppressor gene in breast cancer. The expression of Wnt5a in cell line MCF-7 is positively related with E-cadherin, and it is negatively related with vimentin. Wnt5a may cause invasion and metastasis of breast cancer cell through the breast epithelial mesenchymal transitions.

The essence of endogenous turbidity in Chinese medicine (CM) is different from cream, fat, phlegm, retention, damp, toxicity, and stasis. Along with the development of modern scientific technologies and biology, researches on the essence of endogenous turbidity should keep pace with the time. Its material bases should be defined and new connotation endowed at the microscopic level. The essence of turbidity lies in abnormal functions of zang-fu organs. Sugar, fat, protein, and other nutrient substances cannot be properly decomposed, but into semi-finished products or intermediate metabolites. They are inactive and cannot participate in normal material syntheses and decomposition. They cannot be transformed to energy metabolism, but also cannot be synthesized as executive functioning of active proteins. If they cannot be degraded by autophagy-lysosome or ubiquitin-prosome into glucose, fatty acids, amino acids, and other basic nutrients to be used again, they will accumulate inside the human body and become endogenous turbidity. Therefore, endogenous turbidity is different from final metabolites such as urea, carbon dioxide, etc., which can transform vital qi. How to improve the function of zang-fu organs, enhance its degradation by autophagy-lysosome or ubiquitin-prosome is of great significance in normal operating of zang-fu organs and preventing the emergence and progress of related diseases.

OBJECTIVETo evaluate the anti-tumor effect of the combination of suberoylanilide hydroxamic acid(SAHA) with statins(lovastatin or simvastatin) on non-small cell lung carcinoma(NSCLC) cells.

METHODSHuman NSCLC A549 cells were treated with SAHA in combination of lovastatin or simvastatin. The cell growth was analyzed by SRB method, and the apoptosis of A549 cells was assessed by flow cytometer. The expression of cleaved poly-ADP-ribose polymerase(cleaved-PARP) and p21 protein was analyzed by Western-blotting when A549 cells were challenged with 2.5μmol/L SAHA and 5μmol/L lovastatin.

RESULTSLovastatin and simvastatin synergized SAHA in the inhibition of A549 cells. SAHA induced apoptosis was also enhanced by lovastatin. Treatment with 2.5μmol/L SAHA significantly up-regulated the expression of p21 protein in 48 h, while the protein expression was reduced in combined treatment with 5μmol/L lovastatin.

CONCLUSIONStatins can synergize the anti-tumor effect of SAHA in human NSCLC cells through a p21-dependent way.

OBJECTIVETo determine the effect of the combination of lapatinib with chlorogenic acid on metastasis of breast cancer in mouse model.

METHODSThe classical macrophage M2 polarization model induced by interlukin13in vitro was adopted in the study. Flow cytometric analysis was performed to detect the expression of M2 marker CD206. The transcription of M2-associated genes was measured by RT-PCR. HE staining was used to analyze the metastatic nodes of breast cancer in lungs of MMTV-PyVT mice. Immunostaining analysis was used to detect the expression of related proteins in breast cancer.

RESULTSThe combination of lapatinib and chlorogenic acid inhibited the expression of CD206 induced by IL-13[(42.17%±2.59%) vs (61.15%±7.58%), P<0.05]. The combination more markedly suppressed expression of M2-associated gene Ym1 than lapatinib alone[(0.9±0.1) vs (1.8±0.0), P<0.05]. The combination of lapatinib and chlorogenic acid significantly reduced metastatic nodes in lung[P<0.05], and also significantly decreased the percentage of CD206(+) cells in breast cancer compared to controls[(6.08%±2.60%) vs(29.04%±5.86%), P<0.05].

CONCLUSIONThe combination of lapatinib and chlorogenic acid can effectively inhibit macrophage M2 polarization and metastasis of breast cancer.

OBJECTIVETo identify the expression characteristics of the 1700001022RIK (RIKEN cDNA 1700001022) gene in mice and explore its function by bioinformatic analysis.

METHODSUsing the expression profile of gene microarray, we detected the expression of a new testis-specific gene, 1700001022RIK, in mice. We analyzed its expression characteristics in the testis tissue and their changes in different developmental stages of the testis by RT-PCR, real-time RT-PCR, Western blot, and immunohistochemistry. We performed bioinformatic analysis using a bioinformatic software.

RESULTSThe 1700001022RIK gene was specifically expressed in the mouse testis in an age-dependent manner, most highly in the adult mice. The 1700001022RIK protein was mainly expressed in the spermatogonia, spermatocytes, and round spermatids of the adult mice. Bioinformatic analysis showed that the 1700001022RIK protein amino acid sequence had a high similarity in human and mice, which indicated that this gene was highly conserved in mammals.

CONCLUSION1700001022RIK is a testis-specific gene mainly expressed in the spermatogonia, spermatocytes, and round spermatids of seminiferous tubules, which might be involved in the regulation of spermatogenesis.

OBJECTIVETo explore the effect of hemoperfusion (HP) on tylenol poisoned patients.

METHODSUrgently established the blood access by transfemoral catheterization of femoral vein, we used charcoal hemoperfusion by blood pump and dynamically monitored the plasma concentration of tylenol active ingredients for the 2 patients and the content of tylenol active ingredients in the charcoal was determined.

RESULTSPlasma concentration of tylenol active ingredients of the 2 patients was declined gradually during and after the HP management. The acetaminophen serum concentration of the case 1 was declined from the 13.4 µg/L at the start of HP to the 5.81 µg/L at the end of HP; and the case 2 was declined from 51.1 µg/L to 22.3 µg/L. The adsorption amount of acetaminophen in the blood perfusion device are respectively 119 542 µg of case 1 and 33 2154 µg of case 2.

CONCLUSIONEarly hemoperfusion should be carried out for acute tylenol poisoning patients if there were indications, hemoperfusion can clear the tylenol active ingredients and this is an effective measure to eliminate tylenol active ingredients.
