OBJECTIVE:To prepare Stemoninine orally disintegrating tablets,and to optimize its formulation and preparation technology. METHODS:Direct powder compression method was used to prepare Stemoninine orally disintegrating tablets. Using material angle of repose,disintegration time and taste evaluation as index,single factor test was used to screen several factors as bulking agent,disintegrating agent,glidant and flavoring agent;using disintegration time as index,L9(34) orthogonal test was used to optimize the formulation with ratio of MCC+mannitol,PVPP,silica powder and aspartame+stevia as factors. Validation test was also conducted. RESULTS:Optimized formulation was that MCC+mannitol(1∶1)was 50%,PVPP was 20%,silica powder was 2% and aspartame+stevia(10∶1)was 7%. 3 batches of prepared Stemoninine orally disintegrating tablets were smooth in sur-face and good in taste;their disintegrating time was(22.6±2.1)s,and weight variation,hardness,contents were within the speci-fied range (all RSD≤0.97%,n=3). CONCLUSIONS:The formulation and technology of Stemoninine orally disintegrating tab-lets are reasonable,and the quality indexes are all in line with the requirements of orally disintegrating tablets.

Objective To analysis the levels of serum homocysteine (Hcy)and erythropoietin (EPO)levels in patients with ischemic stroke and their relationship with carotid atherosclerosis.Methods The patients with ischemic stroke admitted be-tween January 1,2013 and July 31,2016 were selected as the subjects.Sera test of Hcy,EPO level,and then through the Doppler probe carotid artery method to check the degree of carotid atherosclerosis in all patients,and the use of quantitative records,according to set diagnostic criteria for classification,the use of grading results with the same type of Hcy,EPO lev-els of data analysis to determine the relationship between the two.Results Doppler exploration in 142 patients showed nor-mal carotid intima-media thickness in 34 patients,carotid intima-media thickening in 56 patients,and carotid plaques in 52 pa-tients.After analysis of variance (F=59.64,78.29,P<0.05),and the difference between the two groups was statistically significant (P<0.05),and the difference between the two groups was statistically significant.The data between any two groups were also statistically significant differences.108 patients with different levels of carotid atherosclerosis were graded into 47 of grade 1,34 of grade 2,and 27 of grade 3,with the same type in the plasma of different grades (F=78.39,48.61, P<0.05).After the qtest,there were no significant differences in the levels of Hcy and EPO.Data were also statistically dif-ferent between groups.Conclusion Serum homocysteine (Hcy)and erythropoietin (EPO)were associated with ischemic stroke and were associated with carotid atherosclerosis.

Objective To study the relationship between serum MMP-9,Gal-3,TGF-β1 and lung function in children with bronchial asthma.Methods The serum levels of matrix metalloproteinase-9 (MMP-9),serum galectin-3 (MMP-9),serum metalloproteinase-3 (MMP 9) and serum albumin were measured in 218 pediatric children between March 1,2012 and August 31,2016 in Shenzhen Longhua New District People's Hospital pediatric outpatient clinic.FEV1％,FEV1/FVC and FEF50 were measured and compared respectively with the index data of the control group.The lung function of the children was significantly higher than that of the control group (P＜0.05).Mild group and severe group children above.Results Serum levels measured in 218 children (F=35.34,46.51,56.73,all P＜0.05).The data of any two groups also showed statistical difference after q test,and the difference was statistically significant (FEV1 ％),1-second forced expiratory volume/forced vital capacity percentage (FEV1/FVC),forced expiratory 50％ (FEF50) of the first-second forced expiratory volume/forced expiratory volume of 1 second (F=78.13,52.69,26.24,all P＜0.05).After the q test,the data of any two groups were analyzed by ANOVA.Between the data were also statistically significant differences.Conclusion MM-9,Gal-3 and TGFβ1 in bronchoalveolar lavage and the degree of pulmonary function decline have close ties.

Objective To investigate the association between FcγRIIA H/H131 genotype and pneumonia through a comprehensive meta‐analysis .Methods Databases including PubMed ,Embase ,and China National Knowledge Infrastructure (CNKI) were searched with such terms as “FcgammaRIIa” ,“FCGR2A” ,“Fcgamma receptor IIA” ,“CD32” and“pneumonia” ,“polymorphism” ,“variant” ,“genotype” ,“allotype” ,as well as“pneumonia”and“polymorphism”in Chinese to identify relevant studies .Two reviewers independently extracted the data .Crude odds ratios (ORs) and corresponding 95%confidence intervals (CIs) were estimated .Heterogeneity across studies and publication bias were evaluated and sensitivity analyses were performed .Results Six case‐control studies were finally included in this analysis .The results indicated an association between FcγRIIA H/H131 genotype and pneumonia susceptibility (OR 1 .67 , 95% CI 1 .11‐2 .51 ) , but no significant association with R/R genotype(OR 1 .09 ,95% CI 0 .85‐1 .40) or H/R genotype(OR 0 .81 ,95% CI 0 .60‐1 .19) . Statistically significant heterogeneity was found during data pooling (I2 was 75 .4 % ,51 .8% and 71 .9% ) .Sensitivity analyses further indicated the reliability of the study .Egger′s and Begg′s tests identified publication bias in R/R genotype ,but not in H/H or H/R genotype .Conclusions We preliminarily find an association between FcγRIIA H/H131 genotype and pneumonia susceptibility .

ObjectiveTo explore the relationship between the mRNA and protein expressions of NIX and the pulmonary alveolus apoptosis following severe acute lung injury (ALI).Methods Rat models of severe collision injury on the chest were built.The mRNA and protein expressions of NIX in the alveolar cells at 6,12,24,48,72 and 96 hours after injury were detected using immunohistochemistry,immunoblotting and RT-PCR.Meanwhile,apoptosis of the alveolar cells was checked at different time points with Tunel assay.ResultsThe protein expression of NIX in the alveolar cells was observed both in experimental and control groups,which increased at 6 h post injury,peaked at 48 h and then declined till approaching the pre-injury level at 96 h.In the meantime,NIX showed a high expression both in the vascular endothelial cells (VECs) and the renal interstitial fibroblasts.The apoptosis of alveolar cells mainly presented in bronchi,blood vessel endothelium (BVE) and alveolar epithelium at 24 h post injury.The post-injury apoptosis rate of the alveolar cells was significantly higher than the pre-injury rate ( P ＜ 0.01 ),which reached the peak at 72 h and then decreased gradually.The changes of NIX protein in lung tissue showed a positive correlation with the apoptosis rate of alveolar cells after injury (r =0.303,P ＜ 0.01 ).ConclusionsThe up-regulated expression of NIX takes part in the pathophysiological process of apoptosis of the alveolar cells and shows consistency with the apoptosis rate change of the alveolar cells,as may be the molecular basis for apoptosis of the alveolar cells after ALI.

astaxanthin is an effective antioxidant and natural pigment which has wide application. Phaffia rhodozyma is a good source of astaxantin, but wild strain has limited use in industry because of low production level of astaxanthin. Several mutants of Phaffia rhodozyma were obtained by exerting mutagen N-methyl-N-nitro-N -nitrosoguanidine. The growth curve suggested that pigments were mainly produced in the middle and latter periods of log phase. The pigments were extracted from Phaffia rhodozyma and analysed by esterification, thin layer chromatography and absorption spectrometry. It was proved that astaxanthin, astaxanthin diester and ?-carotene were the major components of the pigments produced by Phaffia rhodozyma. We also studied the pigments producing phase of Phaffia rhodozyma. and founded that astaxanthin was stable to light under butylated hydroxytoluene coexistance.
