Objective To investigate the effects of Zafirlukast on emotions and Th1/Th2 cytokines in asthmatic children.Methods One hundred and eight asthmatic children were randomly allocated to 3 groups.The children in group A inhaled Pulmicort aerosol 200 ?g twice every day.On the basis of inhaled Pulmicort aerosol,the children in group B took orally Zafirlukast orally 10 mg once every day.The children in group C only took orally Zafirlukast 10 mg once every day.The course of treatment of all children were 4 weeks.Anxiety,depression status and the levels of IFN-? and IL-4 in blood serum were respectively detected before and after treatment.Results Scores of anxiety and depression after treatment in 3 groups were significantly lower than those before treatment(Pa0.05).Conclusions Zafirlukast or Glucocorticoid inhalation has the same effect on improving emotional status and accommodating disequilibrium of Th1/Th2 for asthmatic children,but effect of Zafirlukast combined with Glucocorticoid inhalation are better.

Objective:To explore therapeutic effect of repaglinide on patients with type 2 diabetes mellitus (T2DM) complicated atherosclerosis (AS).Methods:A total of 120 T2DM + AS patients treated in our hospital from Mar 2012 to May 2014 were selected.They were randomly and equally divided into repaglinide group (received repaglin- ide treatment)and glipizide group (received glipizide treatment).Fasting blood glucose (FBG)and 2h postprandial blood glucose (2hPG)levels before and after treatment,serum levels of high sensitive C reactive protein (hsCRP) and oxidized low density lipoprotein (oxLDL)after treatment,and patients'satisfaction on treatment were com- pared and analyzed between two groups.Results:Compared with before treatment,there were significant reductions in levels of FBG and 2hPG in both groups after treatment (P<0.01 all);compared with glipizide group,there were significant reductions in levels of FBG [(6.94±0.41)mmol/L vs.(6.05±0.54)mmol/L],2hPG [(8.03±0.74) mmol/L vs.(7.66±0.78)mmol/L],serum hsCRP [(5.75±0.26)mg/L vs.(4.71±0.32)mg/L]and serum ox- LDL [(98.30±25.05)μg/dl vs.(52.21±17.50)μg/dl]after treatment in repaglinide group,P<0.01 all.Satis- faction rate in repaglinide group was significantly higher than that of glipizide group (93.33% vs.60.00%),P<0.01. Conclusion:Repaglinide possesses significant therapeutic effect on patients with type 2 diabetes mellitus com- plicated atherosclerosis.It can significantly reduce blood glucose,blood lipid and serum hsCRP levels.

Literatures of study on acupoint functional effect of encephalic region with functional magnetic resonance imaging (fMRI) are collected from the database of China National Knowledge Information (CNKI) and Wan fang database. Analysis and comments are made respectively from the status quo of studies on combination of single acupoint, two acupoints and multiple acupoints under both physiological and pathological conditions. The results show that the corresponding encephalic regions can be specifically activated by acupuncture. And different regions can be activated by different acupoints. However, studies on single acupoint, two acupoints and three acupoints are the major researches carried out at present. It is still lack of observation on effect of commonly-used combinations in clinic. Moreover, the reliability of the research results are also affected by disunity of operations protocol, reinforcing or reducing manipulations, intensity or depth of stimulation and duration of needling retention. Therefore, it is necessary to establish a unified and standard operation protocol to strictly control the bias factors which may affect the result of research in the future, and take patients as the study target as much as possible, so as to further explore the central effect mechanism.

Objective To explore the differential diagnostic significance of clone analysis for multicentric occurrence (MO) and intrahepatic metastasis (IM) in hepatocellular carcinomas (HCCs).Methods Loss of heterozygosity (LOH) and microsatellite instability (MSI) were analyzed by microsatellite polymorphism test and the integration sites of HBV were assessed by Southern blot in each nodule of the HCCs. The clonalities were then compared between each nodule of the same patient and the diagnosis of MO or IM was concluded. Finally, the results based on clonality analysis were compared with those according to clinicopathological and imaging data. Results According to the results of LOH and MSI in 79 nodules and nontumorous tissue from 35 cases of mutiple HCCs, 5 (14.3%)and 29 cases (82.9 %) were divided into MO and IM, respectively. Both MO and IM presented simultaneously in 1 patient (2.9%). The integration sites of HBV could be analyzed in 77 nodules from 34 multiple HCCs. Among them, 6 (17. 6%) and 27 cases (79.4%) were divided into MO and IM, respectively. Both MO and IM presented simultaneously in 1 patient (2.9%). The classification results of microsatellite polymorphism test and HBV integration sites analysis demonstrated a significant positive correlation (rs = 0.909, P＜0.001). Nevertheless, neither the classification of microsatellite polymorphism test nor that of HBV integrate sites analysis was correlated with the discrimination according to clinicopathologic and imaging data (rs=0. 133, P=0. 468, rs =0. 262, P=0. 155, respectively). Recurrence in patients in the MO group occurred significantly later than that in IM cases who were diagnosed by clonality analyses (P=0. 001). Conclusion The clonality analysis based on the results of LOH and MSI or assessments of HBV integrate sites is useful for the differential diagnosis of MO and IM and their treatment and prognosis.

Objective To determine the risk factors related to venous thromboembolism after knee arthroscopy. Methods A retrospective study including patients from Feb 2012 to Mar 2016 was carried out to analyze the risk factors of venous thromboembolism after knee arthroscopy. A 1 : 2 matched control group was generated according to the surgeon and the date. Preoperative and perioperative data were collected with respect to age, gender, body mass index, smoking, blood fat, surgical procedure, the time length of ligating tourniquet, anesthesia methods, surgery time and Caprini evaluation. Univariate and multivariate analyses were performed. Results 29 cases of venous thromboembolic events (VTEs) occurred, resulting in an incidence rate of 1.17%. Factors associated with an elevated risk of postoperative VTEs included age OR^ =1.09, 95%CI (1.03, 1.16) and Caprini evaluation OR^ =2.97, 95% CI (1.39, 6.32). Conclusions In this study, VTEs occurred infrequently. Considering the serious result of VTEs, it is important to prevent it. Age and Caprini are associated with elevated risk of postoperative VTEs. It is essential to target those at high risk for VTEs and appropriately treat those patients.

Objective To develop a visible detection system prepared by protein microarrays which was based on GoldMag particles-labeled technique and compare the results of detection using the protein which was labeled with GoldMag particles and colloidal gold.Methods Human IgG was printed on the glass slides modified with epoxy groups,and goat anti-human IgG conjugated with GoldMag particles and colloidal gold respectlively was then added on the slide.The glass slides were incubated,and then the black images of microarray spots were produced by immuno-gold-silver staining method and observed by naked eyes and recorded with common flatbed scanner.Results The high signal-to-noise ratio could be obtained when the optimized procedures of GoldMag particles-labeling probe were introduced to the protein chip.The conditions of optimum assay were as follows:the spotting concentration of human IgG was 0.2 mg/ml,the glass slides were incubated at 37 ℃ for 2 hour to immobilize human IgG,and the silver enhancement time was 10 min-15 min.Parallelly,the optimized conditions for colloidal gold were as follows:the spotting concentration of human IgG was 0.1 mg/ml,the slides were incubated at 37 ℃ for 1 hour to immobilize human IgG,and the silver enhancement time was 15 min-20 min.Conclusions GoldMag particles-labeled protein technique is comparable to colloidal gold in applying to protein microarrays.The method is considerably simple and practical,and the protein labeled by GoldMag particles could be quantitative.

Objective To investigate the effects of tagged fluid and substraction in CT virtual colonoscopy (CTVC) on the conspicuity of polyps and to confirm the optimal attenuation value and the optimal viewing window. Methods Polyps measured 3-10 mm were created in fresh porcine colon in vitro and submerged in saline and mixed with positive contrast medium for the CT values of 200 HU, 400 Hu, 600 HU, and 800 HU. Polyps were measured before and after substraction and compared with those in the control group. The effects of different viewing windows and different attenuation values on the measurement and conspicuity of polyps were analyzed. Results The optimal attenuation value of tagged fluid was 800 HU and the optimal viewing window was colon (-150 HU, 1 500 HU) and bone (500 HU, 2 500 HU). Conclusion The combination of tagged fluid and CT substraction can improve the conspicuity of small polyps covered by colonic fluid.

Objective To estimate the biological effects of leptin on human HaCaT keratinocytes and explore their molecular mechanisms.Methods Cell counting kit-8 (CCK-8) was used to evaluate the proliferation of cultured HaCaT cells treated with different concentrations of leptin for 24 and 48 hours.Some HaCaT cells were classified into four groups to remain untreated,be treated with leptin (100 μg/L) and piceatannol (a specific inhibitor of STAT3 phosphorylation) alone or in combination for 24 hours,respectively,followed by the evaluation of cell proliferation using CCK-8 kit.Flow cytometry was performed to assess cell cycle of HaCaT cells treated with leptin of 100 μg/L,Western blot to determine the phosphorylation level of Erk1/2 and STAT3 in HaCaT cells treated with leptin of 100 μg/L for different durations.Statistical analysis was done by Student's t-test for unpaired data using GraphPad Prism 5 software.Results The proliferation of HaCaT cells was accelerated to different degrees after treatment with leptin of 50 and 100 μg/L for 24 and 48 hours,and the accelerating effect was in a dose-dependent manner within 24 hours (r =0.9989,P ＜ 0.05).Piceatannol apparently inhibited the promotive effect of leptin on the proliferation of HaCaT cells.There was an obvious elevation in the percentage of cells at S phase ((57.70 ± 5.88)％ vs.(42.50 ± 7.55)％,P ＞ 0.05),but a significant decrease in that at G0/G1 phase ((39.70 ± 1.57)％ vs.(45.20 ± 1.44)％,P ＜ 0.05),with a significant increase in proliferation index (0.603 ±0.0157 vs.0.564 ± 0.0144,P ＜ 0.05) in HaCaT cells treated with leptin of 100 μg/L for 24 hours compared with the untreated controls.Western blot showed that leptin of 100 μg/L markedly enhanced the phosphorylation level of STAT3 in HaCaT cells.Conclusion Leptin may upregulate the proliferation of HaCaT cells through activation of STAT3 pathway.
