Objective To investigate the clinical efficacy and safety of montelukast combined with budesonide in the treatment of children with asthma. Methods 70 cases of children with asthma were randomly divided into group A and group B, included 35 cases in each group. Group A was treated with single budesonide and Group B was given montelukast combined with budesonide. The clinical efficacy of two groups of asthma was compared, the body temperature returned to normal time, the time of wheezing disappeared, the normal time of the laboratory index, the normal time of the chest radiograph, the inflammatory factors and the lung function indexes and the side effects. Results The clinical curative effect of group B was higher than that of group A(P<0.05); Body temperature in group B returned to normal time, the time of wheezing disappeared, the normal time of laboratory index was shorter than that of group A(P<0.05); Inflammatory factors and lung function were similar. After intervention, the inflammatory factors and lung function of group B were better than those of group A(P<0.05). There were no obvious side effects in the two groups. Conclusion The clinical efficacy and safety of montelukast combined with budesonide in the treatment of children with asthma can improve the symptoms of children, cause the symptoms to recite in a short time, reduce the inflammatory factors, improve lung function, no obvious adverse reactions, safety effective.

Background A stable diabetic cataract animal model is a premise for screening and evaluating the drug for cataract therapy.Galactose cataract model is widely used in relevant experimental study,but the onset,extent and the type of lens opacification may be different due to different modeling way.Objective This study was to investigate the manifestations and pathological characteristics of cataract induced by D-galactose.Methods Fifty-six SPF SD rats were randomly divided into cataract-model group and control group and 28 rats for each group.50% D-galactose feed was given daily in model group,and regular feed was given in control group.Lenses of rats were examined under the slit lamp through the 30-day period at a 2-day interval,and then the opacity of lenses was graded on the modified Suryanarayana criteria.The body weight of rats was recorded and compared between two groups at day 5,10,15,20,25 and 30.The lenses samples were obtained for the histopathological examination by hemotoxylin and eosin staining.The wet weight,dry weight of the lenes and their ratio were detected and compared between these two groups.The use of animals followed the Regulation for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results The body weight was reduced in model rats compared with control rats with the statistically significant difference from 10 days through 30 days(P＜0.05).The different grades of opacification of lens cortical and nuclear progressed in model rats throughout the experiment duration,but the lenses were clear in control rats.The slit-lamp microscopy and pathological examinations revealed that lenses opacity in model rats started from the cortex at the equator zone and developed towards central zone gradually with the lapse of experimental time.Following the entire opacity of lens cortex,lens nucleus were cloudy and expanded.The swelling and degeneration of the fiber cells in lens cortex,the differentiation,migration and denuclearation delay of lens epithelial cells were seen in model rats under the light microscope.The wet weight of lenses was increased and the dry weight was decreased in model rats in comparison with control rats in experimental 30 days,showing significant difference between two groups(t=138.571,t=52.468,P＜0.05).Conclusion The development of galactose-induced cataract animal model resemble one of age-related cortical cataract in human with the similar generating mechanism.This cataract model is reproducible and classifiable.

Background Sugar cataract is one of the major diabetic complications in the eye,but there is not effective medicine to prevent or delay development of cataract. Objective The goal of this study was to investigate the effects and the potential mechanism of aldose reductase (AR) inhibitor,AL-1576 on prevention of galactose cataract in rats. Methods Forty-two SD rats were randomly and equally divided into 7 groups.The cataracts were induced by feeding with 50％ galactose.At the day of feeding galactose and the day 5,10 and 15 after feeding galactose,AL-1576 was added into the feeds.The rats were divided AL-1576 prevention group and early-,intermediate-or late-stage intervention groups.For another group,the withdrawing AL-1576 group,AL-1576 was added into the feeds at the day of feeding galactose,then was removed after 10 days.The lenses of the rats were examined under the slit-lamp microscope before and after given AL-1576 every 5 days.At the day 35,the lenses were obtained.The wet and dry weight of the lenses were weighted,respectically,to calculate the water content of the lenses.Activities of AR and superoxidedismutase (SOD) and contents of glutathione (GSH) of the lenses were measured by their commercial detecting kits.The care and use of the animals complied with the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission. Results In AL-1576 prevention group,all lenses maintained clear.Opacification of the lenses were significantly attenuated in all three AL-1576 intervention groups and withdrawing AL-1576 group compared with the cataractous model group ( P＜0.05),but the inhibiting role was weaken with late intervention.The water contents and the activities of AR of the lenses were decreased,the contents of SOD and GSH were dramatically increased in all different AL-1576 treated groups compared with the cataractous model group (P＜0.05).Moreover,AL-1576 prevention group showed the best effect on all indexes (P＜0.05). Conclusions The activity of AR can be inhibited by AL-1576 at the different stages of development of cataract induced by galactose.By blocking and attenuating formation of the edema and elevating antioxdative capacity in the lenses,AL-1576 prevents and delays the formation of galactose cataract.

Objective To investigate the relationship between metabolic syndrome (MS) and education level in Su-Xi-Chang area to provide evidence for healthcare policy making. Methods A clustered sampling of 6798 subjects from Su-Xi-Chang areas of Jiangsu Province was included. Questionnaires and physical examinations were completed to collect clinical data. Logistic regression was used to analyze weather education level could be an independent risk factor of MS. Results Significant differences were found in waist circumstance (WC) ,systolic blood pressure (SBP) and fasting blood glucose (FBG) among participants with different education level. Significant differences were also existed in triglyceride and diastolic blood pressure (DBP) between subjects with higher and lower education level ( P＜0. 05 ). In single-factor or multivariate analysis, education level was negatively correlated with the prevalence of MS (P＜0. 05 ). Conclusions Education level may be an independent risk factor of MS. People with low and moderate education level have higher risk of MS. Therefore,it is recommended that health-related information should become an integral part of the compulsory education system.

Objective To investigate the relationship between metabolic syndrome (MS) and diet style in the elderly. Methods The 781 old people were consecutively selected. Related data were collected by means of questionnaires and physical examinations. And logistic regression was performed to analyze if moderate and high fat diet were risk factors of MS. Results The total prevalence rate of MS in old people was 40. 7%, with 36.7% in old males and 55.4% in old females,and the prevalence rate of MS was higher in old women than in old men (P=0. 000). The significant differences in waist circumferences among three groups of low, moderate and high-fat diet [(86.0±9.3) cm vs. (88.8±8.5) cm vs. (90. 0±7.9) cm, respectively (all P＜0.05)]were found. Fasting blood glucose showed a significant difference between two groups of low and high-fat diet, with the results of (5.78 ± 0.98) mmol/L and (6.27 ± 1.80) mmol/L, respectively ( P＜0. 05 ). The logistic regression analysis showed that odds ratio for people with moderate and high-fat diets were 1. 541 ( 1. 092-2. 174) and 2. 293 ( 1. 317-3. 994), respectively (P＜0.05), which indicated that moderate and high-fat diet was independent risk factors for MS in old people. Conclusions Both moderate and high-fat diets are risk factors of MS in old population, low fat diet with food balance is recommended to old population in order to decrease the prevalence of MS.
