Objective To compare the clinical effect of montelukast sodium and ketotifen in the treatment of children with cough variant asthma,thus to provide theoretical basis for clinical treatment.Methods 61 children with cough variant asthma were randomly divided into control group and observation group according to the digital table method,31 cases in each group.Patients of two groups were all given antispasmodic and antitussive.The control group was given ketotifen tablets drug therapy,1mg/time,2 times/d,and the observation group was treated with montelukast chewable tablets,5mg/time,1 time /d.After 8 weeks of treatment,the clinical effects were compared between the two groups.Results The total effective rate of the observation group (96.77%)was higher than that of the control group (77.42%),and the difference was statistically significant (χ2 =16.65,P <0.05).The clinical symptoms improved time of the observation group was (5.78 ±1.36)d,which was shorter than (8.45 ±2.24)d of the control group,the difference was statistically significant (t =2.71,P <0.05).The recurrence rate of the observation group (6.45%) was lower than the control group (16.13%),the difference was statistically significant (χ2 =4.67,P <0.05 ). Recurrence time of the observation group was better than that of the control group,the difference was statistically significant (t =7.98,P <0.05 ).Conclusion The curative effect of montelukast special chewing tablets in the treatment of children with bronchial asthma is obviously superior to ketotifen,has less adverse reactions.It was worthy of clinical application.

Objective To observe the changes of the multifocal electroretinograph (mf-ERG) in commotio retinae. Methods The affected eyes (traumatic group) and the fellow eyes (control group) of 31 patients with unilateral commotio retinae were examined by RETI scan 3.15 system. The responses of 61 retinal regions were recorded, and the average amplitude densities of the N 1 (the first negative) wave and P 1 (the first positive) wave in different regions of retinal were analyzed. Results The average amplitude densities of 1-4 rings in N 1 wave and 1-5 rings in P 1 wave were much lower in traumatic group than those in the control. Conclusions The average amplitude densities of N 1 wave and P 1 wave of mf-ERG in retinal affected regions decreases markedly in eyes with commotio retina; mf-ERG may provide the quantificational and orientational detection for the visual ability of the eyes with commotio retinae.

Objective To investigate the risk factors of gallbladder neoplastic polyps,to determine the proper surgical indications,and to understand more about the clinical characteristics of gallbladder adenoma.Methods The clinical data of 748 patients diagnosed to have polypoid lesion of gallbladder (PLG) and underwent cholecystectomy from January 1998 to December 2012 in the Second Affiliated Hospital of Zhejiang University School of Medicine were retrospectively reviewed.Results Among 748 patients,340 had abdominal symptoms.Postoperative histopathology showed non-neoplastic polyps (n =659),gallbladder adenoma (n =68),gallbladder cancer (n =15) and no polyps (n =6).The mean diameters of the nonneoplastic lesions and the neoplastic polyps were (9.38 ± 3.44) mm and (14.55 ± 5.71) mm,respectively (P ＜ 0.01).The average age of the patients with non-neoplastic lesions was (44.14 ± 11.42) years and (47.39 ± 12.82) years in those with neoplastic polyps (P ＜ 0.05).The proportion of solitary PLG was 41.4％ (253/611) and 59.59％ (47/79) for the non-neoplastic lesions and the neoplastic polyps respec tively (P ＜ 0.01).The size of PLG (13.34 ± 4.18 mm vs.20.07 ± 8.19 mm,P ＜ 0.05) and the age of the patient (45.78 ± 11.66 years vs.54.13 ± 15.82 years,P ＜0.05) between the gallbladder adenoma and gallbladder cancer groups were significantly different.Gallbladder adenoma or dysplasia was identified in 66.7％ (10/15) of gal1bladder cancer specimens.Conclusions Patients with PLG and with abdominal symptoms,large size (≥ 10 mm),old age (≥50 y) and solitary polyp are indications for cholecystectomy.Gallbladder adenoma may develop to gallbladder cancer within 10 years.

Objective To investigate the clinical value of multi-slice spiral CT (MSCT)in diagnosis of internal abdominal hernia (IAH).Methods The MSCT findings in 1 5 patients with IAH confirmed by surgery were retrospectively analyzed.Results MSCT showed intestinal obstruction in 14 patients with strangulating intestinal obstruction in 8.The typical features of MSCT were as follows:translocated position of intestines (occupying effect),closed loop intestinal obstruction (gathered intestinal loops with different forms),assembled,expanded and translocated blood vessels of mesenteries,and thickened intestinal walls with ischemic edema and abnormal density.Surgical results showed paraduodenal hernia in 2,transomental hernia in 2,transmesenteric hernia in 5,ankylenteron strap hernias in 4,pericecal hernia in 1 and hernia through the Douglas fossa in 1,Intestinal obstruction in 14 and strangulating intestinal obstruction in 8 were also confirmed by surgery.The CT findings of IAH were correlated with the surgical results,and the accurate rate of grading of intestinal obstruction with CT was also consistent with the surgical results (Kappa=0.758,t=3.462,P=0.001).Conclusion IAH can be diagnosed accurately by MSCT in most patients,MSCT is helpful for guiding the surgical programs.

Objective: To investigate the relationship between the Smad4-independent pathway of TGF-?1 and drug-resistance of pancreatic cancer. Methods: The sensitivities of Smad4 homozygous-deleted pancreatic cancer cell line BxPC3 to different kinds of anti-cancer drugs (5-Fu, Gemzar, Oxaliplatin, Cisplatin, CPT-11 and Epirubicin) were observed by MTT assay before and after they were transfected with full-length cDNA of TGF-?1 or treated with TGF-?1 (5 and 10 ng/ml) solution. Western blot was used to detect p170 protein expression after stimulation with different concentrations of TGF-?1. Results: Cisplatin had the most powerful killing effect on BxPC3 cells, followed by Oxaliplatin, 5-Fu and CPT-11 with moderate effect and Gemzar and Epirubicin with the least effect. Cells transfected with full-length cDNA of TGF-?1 or treated with TGF-?1 solution became less sensitive to Cisplatin. Western blot revealed upregulation of p170 expression by TGF-?1. Conclusion: The Smad4-independent pathway of TGF-?1 can increase the drug resistance of pancreatic cancer cells through upregulating expression of p170.
