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.

AIM: To determine the effect of suction duration on thickness and diameter of corneal flap created by microkeratome in porcine eyes in laser in situ kerato-mileusis (LASIK).METHODS: Sixty porcine eyes were randomly assigned to three groups according to different suction durations: group 1 (10 seconds), group 2 (20 seconds), and group 3 (30 seconds). A Moria M2 microkeratome (Moria, France) with a 160μm head was used to create a corneal flap. Corneal flap thickness was measured by automated ultrasonic pachymetry, and the flap diameter was measured by a vernier caliper.RESULTS: The flap thickness of group 1, group 2 and group 3 was 146.05±13.46μm, 157.35±18.95μm and 169.25±21.02μm, respectively. There was a statistically significant difference among three groups (P=0.001). The mean flap diameter in groups 1, 2 and 3 was 8.63±0.19mm, 8.89±0.24mm and 9.06±0.18mm, respectively. A statisti-cally significant difference was found among groups (P<0.01).CONCLUSION: In LASIK in porcine eyes, an increase in suction duration resulted in a thicker and greater flap.

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.

BACKGROUND:Elderly patients have more loose bone. After fractures, bones are mostly crushed. Simultaneously, many elderly patients experience many internal diseases. Various organs have dysfunction. Surgery tolerance is poor, which also brings difficulty in treatment with internal fixator, and increases the risk of therapy. Thus, the choice of internal fixation method is not uniform. OBJECTIVE: To compare and analyze the repair effects of proximal femoral nail anti-rotation blade and anatomic proximal femoral locking plate in treatment of unstable intertrochanteric fractures in the elderly. METHODS:A total of 100 elderly patients with unstable intertrochanteric fractures were selected from the Youyi Branch, Kunshan First People’s Hospital from April 2011 to June 2013. They were randomly assigned to two groups. Patients in the experimental group received internal fixation with proximal femoral nail anti-rotation blade. Patients in the control group received anatomic proximal femoral locking plate. After treatment, folow-up was conducted. Operative indexes, postoperative Harris score for hip function and incidence of complications were compared and analyzed in both groups. RESULTS AND CONCLUSION: No significant difference in various indexes was detected in both groups (P > 0.05). Harris scores were significantly better in the experimental group than in the control group (P < 0.05). Postoperative complications were significantly less in the experimental group than in the control group (P < 0.05). These results indicated that internal fixation of proximal femoral nail anti-rotation blade for unstable intertrochanteric fractures in the elderly achieved satisfactory results in the recovery of joint function and had the advantage of few complications.

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.

Objective To evaluate the effect of Rab23 on the proliferation of a squamous cell carcinoma cell line Sa3,and to investigate its mechanisms.Methods Cultured Sa3 cells were classified into four groups:normal control group transfected with green fluorescent protein (GFP),Rab23-overexpressing group transfected with a GFP-labelled Rab23-overexpressing plasmid,Rab23-silencing group transfected with a plasmid carrying a Rab23-targeting shRNA,empty vector group transfected with an empty vector.After additional culture for different durations,plate colony formation assay and flow cytometry were performed to evaluate the proliferative activity of Sa3 cells,and Western blot was conducted to detect the expression of Erl/phosphorylated-Erk in Sa3 cells.Statistical analysis was carried out by t test,one-way analysis of variance and Bonferroni's multiple comparison test.Results Stable Sa3 cell lines with overexpression or silencing of Rab23 were established by plasmid construction and lentivirus-mediated transfection.The plate colony formation assay showed that the colony formation rate was significantly lower in the Rab23-overexpressing group than in the normal control group (2.3％ ± 0.2％ vs.3.6％ ± 0.3％,P ＜ 0.05),but higher in the Rab23-silencing group than in the empty vector group (4.1％ ± 0.2％ vs.1.8％ ± 0.03％,P ＜ 0.01).Rab23 overexpression induced G1 phase arrest in Sa3 cells.The proliferation index was significantly decreased in the Rab23-overexpressing group compared with the normal control group (0.581 ± 0.035 vs.0.698 ± 0.018,P ＜ 0.05),but increased in the Rab23-silencing group compared with the empty vector group (0.567 ± 0.015 vs.0.444 ± 0.014,P ＜ 0.01).As Western blot showed,there were no significant changes in the expression of Erk in the Rab23-silencing or-overexpressing group compared with the normal control group,whereas the expression of p-Erk was attenuated in the Rab23-overexpressing group compared with the normal control group,but enhanced in the Rab23-silencing group compared with the empty vector group.Conclusions Rab23 could inhibit the proliferation of Sa3 cells,which may be associated with the Erk pathway.
