OBJECTIVE:To compare the clinical efficacy and safety of salmeterol-fluticasone alone versus fluticasone propio-nate combined with montelukast sodium in the treatment of children with moderate persistent asthma. METHODS:275 children with moderate persistent asthma were randomly divided into inhaled corticosteroids(ICS)+ long acting β2 receptor agonist(LABA) group (139 cases) and ICS+ leukotriene receptor antagonists (LTRA) group (136 cases). ICS+LABA group was given Salmeter-ol-fluticasone powder inhalant,1 inhalation,bid;ICS+LTRA was given Fluticasone propionate inhalation aerosol,bid+Montelu-kast sodium chewable tablet 5 mg,before bedtime,qd. Both groups received more than 12 weeks of treatment. Body indexes of 2 groups were observed after treatment,such as asthma control degree,asthma score,the percentage of peak expiratory flow(PEF) in estimated value,aberration rate of PEF,the levels of eosinophi cationic protein(ECP)and leukotrienes E4(LTE4)in peripheral blood,the times of taking short acting β2 receptor agonist (SABA) during treatment,asymptomatic days,compliance,the inci-dence of ADR,etc. RESULTS:Total effective rate of ICS+LABA group(86.33%)after 4 weeks treatment was higher than that of ICS+LTRA group(58.09%),with statistical significance(P<0.05);that of ICS+LABA(99.28%)after 12 weeks treatment was higher than that of ICS+LTRA group (98.53%),without statistical significance (P>0.05). The day and night asthma score of 2 groups decreased significantly and the percentage of PEF in estimated value increased significantly after treatment,there was statisti-cal significance compared to before treatment(P<0.05). There was no statistical significance in above indexes between 2 groups af-ter treatment(P>0.05). The levels of ECP and LTE4 decreased significantly in 2 groups after treatment,there was statistical signif-icance compared to before treatment(P<0.05);those of ICS+LTRA group decreased significantly compared to ICS+LABA group, there was statistical significance between 2 groups(P<0.05). There was no statistical significance in the aberration rate of PEF af-ter treatment,the times of taking SABA,asymptomatic days,compliance and the incidence of ADR between 2 groups during treat-ment(P>0.05). CONCLUSIONS:Salmeterol-fluticasone alone versus fluticasone propionate combined with montelukast sodi-um in the treatment of children with moderate persistent asth-ma both have good therapeutic efficacy and safety,while thelatter one has stronger inhibition effect on ECP and LTE4,and to control asthma symptoms more rapidly.

Objective: To study the effect of curcumin on cardiac remodeling and heart function change induced by adriamycin in rats. Methods: A total of 50 SD rats were randomly divided into blank control group (n=10), adriamycin group (n=20) and curcumin intervention group (n=20). General conditions of rats, including weight, hair color, diet and activity capacity, were observed. Left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS) and left ventricular end-diastolic dimension (LVEDd) were observed by echocardiography. Rat heart was weighed and levels of cardiac collagen type Ⅰ and Ⅲ were observed using immunohistochemistry method. Results: Compared with blank control group after experiment, there were significant increase in heart weight [(168.53±26)mg vs. (208.34±31)mg], heart weight/body weight [(0.36±0.06) vs. (0.52±0.08)], and significant decrease in body weight [(469.27±34)g vs. (428.47±45)g]; significant increase in LVEDd [(4.87±0.19)mm vs. (7.49±0.83)mm], significant decrease in LVEF [(69.53±6.25)% vs. (41.46±4.38)%] and LVFS [(45.83±3.79)% vs. (17.25±2.92)%] in adriamycin group, P<0.05 all, significant increase in expression rates of collagen type Ⅰ and Ⅲ, P<0.01.Compared with adriamycin group, there were significant increase in body weight (452.46±38)g, significant decrease in heart weight (178.73±38)mg, heart weight/body weight (0.39±0.07); significant decrease in LVEDd (5.96±0.65)mm and significant increase in LVEF (53.12±5.43)% and LVFS (36.57±3.66)%, P <0.05 all; significant decrease in expression rates of collagen type Ⅰ and Ⅲ in curcumin group, P <0.01.

Objective To investigate the effect of diuretics combined with the new class volume-removing drugs nesiritide and tolvaptan on refractory heart failure (RHF).Methods We collected 78 patients with RHF from cardiovascular ICU in our hos-pital,and patients were divided into combined volume-removing drugs treatment group (CVR group)and traditional diuretics com-bined with inotropic treatment group (control group).We observed the differences in the heart failure symptoms control rate and the average hospitalization days between the two groups.The difference in average urine volume and weight loss during hospitaliza-tion was observed.Results The heart failure symptoms were controlled and successful discharge in 89.7% of patients in CVR group,which was better than that in control group(71.8%).The corresponding rates of death or abandonment was decreased sig-nificantly in CVR group,and the average number of hospitalization days in CVR group was significantly shorter than that in control group(P <0.05).Meanwhile,the average daily urine volume and the weight loss decreased significantly in CVR group than those in control group(P <0.05).Conclusion The therapy strategy of combined volume-removing drugs can significantly improve the vol-ume removing and control rate of heart failure symptoms.

Objective:To investigate influences of two different HLA-B antigens expressed on K562 cells on receptors expression of NK cells from peripheral blood lymphocytes.Methods:Studied the alteration of the percentage of CD16+CD56+ cells and the percentage of KIR3DL1+ cells before and after PBMC interaction with K562 cells for 24 hours,and also compared the percentage of CD16+CD56+ cells and the percentage of KIR3DL1+ cells after PBMC interaction with two different kind of K562 cells transfected with HLA-B39 and HLA-B51 respectively.Results:After PBMCs were incubated with K562 cells for 24 hours,the percentage of CD16+CD56+ cells and the percentage of KIR3DL1+ cells were both increased.However,after PBMCs were incubated with K562-HLA-B51 cells for 24 hours,the percentage of KIR3DL1+ cells and the percentage of CD16+CD56+ cells were both decreased in comparison with that interaction with K562-HLA-B39 cells.Conclusion:CD16 up-regulation was associated with an up-regulation of inhibitory receptors(KIR3DL1).The interaction between HLA-Bw4 and KIR3DL1 would down-regulate the expression of KIR3DL1.In addition,KIR3DL1 down-regulation was associated with down-regulation of activating receptors(CD16).

Objective To investigate whether MICA gene exon 2,3 and 4 polymorphism is associated with seronegative spondylarthropathies (SpA) or not in Chinese Han population.Methods All 199 B27 positive patients with SpA and 183 randomly ethnically matched healthy controls,and 12 B27 positive controls were enrolled to detect the MICA genotype from its exons 2,3 and 4 by using PCR SSOP method in Shanghai area.Results The MICA007 allele frequency was significantly more in the patient group (18 0%) than in the randomly healthy control group (6 6%) (RR=3 04, P =0 000 045).However,the MICA007 allele frequency was not significantly higher in the B27 positive patient group than in the B27 positive control group.Conclusion The MICA007 allele itself may not be the real disease susceptibility gene involved in the development of ankylosing spondylitis.The increased frequency of MICA007 allele is supposed to be due to a strong linkage disequilibrium between MICA and HLA B genes.

Objective To investigate whether the killer cell immunoglobulin like receptor (KIR) gene polymorphisms are associated with seronegative spondylarthropathies.Methods All 197 HLA B27 positive patients with seronegative spondyloarthro pathies (SpA) and 83 randomly ethnically matched healthy controls were enrolled to detect the KIR genotype using PCR SSP in Shanghai area.Results The KIR3DL1 gene frequency was significantly lower in the patient group (0 763) than in the control group (1 00) (RR=0 76, P =0 003).Meanwhile,the gene frequencies of two pseudogenes (KIR2DP1,KIR3DP1) were significantly higher in SpA group than in healthy control group (RR=1 1, P =0 004).Conclusion There may be a negative association between pathogenesis of SpA and KIR3DL1 gene.The function of KIR3DL1 molecule should be investigated deeply.

Objective:To explore the oral health status of population in Gansu Province and get scientific information for oral diseases prevention. Methods: An equal-sized stratified multi-stage random sampling design was applied in the investigation. According to standard and method used in the third national oral health epidemiological investigation, the oral health investigation was made in 3 158 people aged 5 years, 12 years, 35-44 years and 65-74 years with a gender ratio of half to half in Gansu. Results: The caries prevalence rate was 55.80%, 19.09%, 61.95% and 78.63% and the caries-filling rate was 3.11%, 10.76%,10.34% and 4.60% in the four groups respectively. Detection rates of gingival bleeding and dental calculus were 82.81%, 93.55%, 85.34% and 69.66%, 99.37%, 92.54% in 12, 35-44 and 65-74 groups respectively. Detection rates of periodontal pocket and diseases of oral mucosa were 60.94%, 62.20% and 6.32%, 7.71% in 35-44 and 65-74 groups respectively. The most denture-prosthesis was removable partial dentures and irregular fixed bridge. Conclusion: The prevalence of caries is serious but better than the average results of the nation in 2005 and the results of Gansu in 1995. The prevalence of periodontal disease is more serious than the results of the nation in 2005. It is essential to strengthen oral health education and oral health service, especially in rural area in Gansu, so as to ensure the oral diseases be treated in time and effectively.

Objective To establish the reference interval for serum prostate-specific antigen (PSA) in apparent healthy men of different ages in Nanjing.Methods A total of 25 820 healthy men undergoing routine physical examinations in the First Affiliated Hospital of Nanjing Medical University from October 2013 to September 2015 were selected for the study.All of them were screened by prostate B ultrasound,excluding abnormal urinary tract diseases.The concentration of serum PSA and free prostate-specific antigen (fPSA) were measured by automatic luminescence immunoassay analyzer,and the fPSA/PSA values were calculated.The participants were divided into four groups (20～ 39,40～ 59,60～ 79 and older than 80 years old groups),then the median,5th,25th,75th and 95th percentiles of both PSA and fPSA/PSA were counted,respectively.Results The median of PSA (95th percentile ranges) of these groups by age from low to high were 0.78 (1.93),0.90 (2.93),1.34(6.60) and 2.01(11.91),respectively.The 25th to 75th percentiles were 0.55～1.11,0.61～1.36,0.77～2.51 and 0.94 ～ 4.19,respectively.The median of fPSA/PSA (95 th percentile ranges) were 0.37 (0.60),0.31 (0.56),0.28 (0.53) and 0.29(0.52),respectively.The 25th to 75th percentiles were 0.28～0.46,0.23～0.40,0.22～0.36 and 0.23～ 0.37,respectively.Among all the groups,median differences of both PSA and fPSA/PSA were statistically significant (P＜0.05),and PSA levels rise with age.PSA levels in different regions were different.Conclusion The PSA level of men under 40 years in Nanjing should be 0～2.5 ng/ml,40～60 years should be 0～4 ng/ml,while men who are above 60 years,could use 0～5 ng/ml as reference interval.
