Objective To investigate the role of CD4+CD25+FoxP3+ in severe Mycoplasma pneumonia among children.Methods One hundred and forty children with M.pneumoniae pneumonia (65 severe and 75 non-severe) who were hospitalized were enrolled along with forty other children as controls.X-ray was assessed.The proportions of peripheral blood CD4+CD25+FoxP3+cells were determined by flow cytometry.Results Both severe and non-severe children had decreased CD4+CD25+FoxP3+cells as compared with control subjects in acute phase (0.87 ± 0.66％ vs.3.88 ± 2.00％,P ＜ 0.01 and 1.17 ± 0.70％ vs.3.88 ±2.00％,P ＜0.01,respectively).The levels of CD4+CD25+FoxP3+cells in severe children were lower than those in non-severe children in acute phase and recovery phase (0.87 ±0.66％ vs.1.17 ±0.70％,P ＜0.05 and 1.66 ±0.85％ vs.3.61 ± 1.45％,P＜0.01,respectively).Both severe children and non-severe children expressed higher CD4+CD25+FoxP3+cells in recovery phase than in acute phase (1.66 ± 0.85 ％ vs.0.87 ± 0.66％,P ＜0.01 and 3.61 ± 1.45％ vs.1.17 ±0.70％,P ＜0.01,respectively).Conclusion The expression of CD4+CD25+FoxP3+Tregs may play a role in the onset of severity of mycoplasma pneumonia and the low express of CD4+CD25+FoxP3+Tregs in children infected with M.pneumonia may increase the susceptibility to severe mycoplasma pneumonia.

Objective Published literatures on the relationship between IL-13 gene polymorphism and the susceptibility of children to bronchial asthma in China were comprehensively analyzed with the use of Meta-analysis to evaluate this relationship.Methods The data were collected from the Medline database,Ovid database,the Cochrane library,and Chinese Biomedical database,and the references of eligible studies were manually screened.Published data related to case-control studies reporting the link between IL-13 polymorphisms and asthma in Chinese children were retrieved through those database.Meta-analysis was conducted to determine whether the IL-13 gene polymorphisms were associated with asthma.Results Eighteen studies were finally accepted for analysis.There were three studies focusing on C-1 112T polymorphism,and six studies focusing on C + 1923T polymorphism,and fourteen studies focusing on G + 2044A polymorphism.There was no evidence to confirm that the genotypes in position IL-13-1112 C/T were associated with asthma in Chinese children [odds ratio(OR) =1.00,95％ CI 0.82-1.22,P =0.98].The OR of asthma for TT/CC genotypes was 1.15 (95 ％ CI 0.57-2.33,P =0.69) and for CT/CC was 1.01 (95 ％ CI 0.82-1.25,P =0.89).There was significant evidence to confirm that the genotypes in position + 1923 C/T were associated with asthma in Chinese children(OR =1.86,95％ CI 1.29-2.67,P =0.000 9).The OR of asthma for TT/CC genotypes was 2.12 (95 ％ CI 1.27-3.56,P =0.004) and for TC/CC was 1.67 (95％ CI 1.18-2.35,P =0.003).There was no correlation between IL-13 + 2044G/A polymorphism and the susceptibility (OR =1.33,95％ CI 0.94-1.88,P =0.11).The OR of asthma for AA/GG genotypes was 1.30 (95 ％ CI 0.76-2.20,P =0.34) and for AG/GG was 1.24(95％ CI 0.90-1.70,P =0.19).Conclusions IL-13 gene + 1923 TT and TC genotypes should be associated with susceptibility of asthma in Chinese children,and the T allele could increase the risk of asthma.No clear relationship was found between the genotype TT/TC at the IL-13-1112 site and the incidence of asthma of children in China,and so was the genotype AA/AG at the IL-13 +2044 site and the incidence.

OBJECTIVE:To achieve the drug intelligent supervision in transportation within hospital and storage process,and promote quality safety of drugs. METHODS:The function and operation of Radio frequency identification(RFID)medicine logis-tic box was introduced,its application in one year in inpatient pharmacy of our hospital since Sept. 2013 was summarized,and its application effect and deficiency were analyzed. RESULTS:RFID medicine logistic box showed heat preservation and locking func-tions,which can be used for the cold-chain medicine and lock packing transportation for the ward. It can achieve information bind-ing after connecting with corresponding platform,record real-time record temperature,logistic box opening and closing information and data,as well as a variety of ways to alarm by SMS and mail,etc. However,failed login server and unpacking caused by unsta-ble wireless signals were found when applying the box,also drug damage and other defects were caused by unreasonable box struc-ture. And the daily average incidence dropped from the initial period (Nov. 2013) 11.9 times (cases) to the late period (Sept. 2014) 3.3 times (cases) after continuous improvement. CONCLUSIONS:Applying of medicine logistic box can strengthen cold-chain transport integrity and regulatory information in our hospital,ensure the safety of drug transport and query traceability of information.

The degranulation of mast cells represents a pivotal e-vent in the allergic disorders.The Src family kinases(SFKs)are as a starting signal in the activation of mast cell.Lyn,Fyn and Syk play important regulatory role in the degranulation of mast cells.Regulating SFKs can reduce the degranlation process and inhibit the allergic disorders.Therefore,SFKs inhibitors can be potential drugs in the allergy.It is necessary to study the targeted medicine of SFKs,which will be a new direction of drug develop-ment.

The most common forms of treatment for amblyopia are occlusion therapy and pharmacologic penalization. But these methods can not recover all the visual deficits of amblyopes and there are some disadvantages of the treatment which need to be considered, including adverse effects, compliance and social stigma. Recently, some novel approaches are investigated for improving the effectiveness and compliance of treatment for amblyopia.

Objective To observe the effect of Chaihushugansan combined with fluoxetine on interleukin -6 ( IL-6 ) , interleukin -1β( IL-1β) , tumor necrosis factor ( TNF-α) in the treatment of patients with postpartum depression.Methods 83 patients from November 2013 to July 2015 in Jiaxing Maternity and Child Health Care Hospital were randomly divided into 41 patients of observation group and 42 patients of control group.The control group were treated with fluoxetine treatment, the obsercation group received Chaihushugansan on the basis of control group.The Hamilton depression scale (HAMD) and Hamilton anxiety scale (HAMA),IL-6, IL-1β, TNF-α, high-sensitivity C-reactive protein (hs-CRP) and adverse reactions were followed up and recorded.Results The HAMD and HAMA score in observation group post-treatment were (8.31 ±2.05,9.03 ±2.08)points, which were lower than (13.96 ±2.16, 13.61 ±2.14) points in control group (P<0.05).The serum IL-6 and IL-1βlevels in observation group post-treatment were (6.59 ±3.20,5.01 ±2.83)pg/mL, which were lower than (10.64 ±3.86,9.31 ±3.42)pg/mL in control group (P<0.05).The serum TNF-αand hs-CRP levels in observation group post-treatment were ( 9.16 ±2.01 ) pg/mL, ( 3.62 ±1.06 ) mg/L, which were lower than ( 12.30 ±2.37 ) pg/mL, (5.29 ±1.14)mg/L in control group (P<0.05).The total adverse reaction rate in observation group was 7.32%, significantly lower than 23.81% in control group ( P <0.05 ) .Conclusion Chaihushugansan combined with fluoxetine has a good therapeutic effect in the treatment of postpartum depression, could significantly reduce the IL-6, IL-1β, TNF-α levels, with fewer side effects, it is better than fluoxetine alone.

ObjectiveTo investigate the effects of grape seed proanthocyanidin extracts (GSPE) on advanced glycation end product receptor (RAGE),NF-Κb and connective tissue growth factor (CTGF) in the myoeardium of diabetic rats.MethodsTotal 30 streptozotocin (STZ) induced diabetic rats were randomly divided into 2 groups:diabetic group (DM1,n-15) and GSPE (250 mg/ kg,i.g) treated diabetic group (DM2,n= 15).Another two control groups:normal rats(C1,n= 10)and normal rats treated with GSPE (250 mg/kg,i.g) (C2 group,n= 10) were also observed.After 24 weeks,blood was collected to measure fasting plasma glucose (FBG) and RAGE.The protein expression of NF-Κb was determined in myocardial tissue by immunohistochemical staining and Western blot.The protein expressions of RAGE and CTGF were measured by Western blot.Results The levels of FBG and RAGE were significantly higher in diabetic rats than in control rats (P＜0.05).After GSPE treatment,RAGE level significantly reduced (P＜0.05),but FBG had no change in diabetic rats.The protein expressions of RAGE,NF-Κb and CTGF in the myocardial tissue of diabetic rats had marked increase compared with control rats (P＜ 0.05),however,their levels significantly reduced after GSPE treatment (P＜0.05).ConclusionsGSPE may protect diabetic rats against cardiomyopathy,possibly by decreasing the protein expressions of RAGE,NF-Κb and CTGF.

The purpose of this study is to investigate the effects of multiple-trough sampling design and nonlinear mixed effect modeling (NONMEM) algorithm on the estimation of population and individual pharmacokinetic parameters. Oxcarbazepine and tacrolimus were used as one-compartment and two-compartment model drugs, respectively. Seven sampling designs were investigated using various number of trough concentrations per individual ranging from 1-4. Monte Carlo simulations were performed to produce state-steady trough concentrations. One-compartment model was used to fit simulated data from oxcarbazepine and tacrolimus. The accuracy and precision of the estimated parameters were evaluated using the median prediction error (PE), the median absolute PE and boxplot. The results indicated that trough concentrations could yield reliable estimates of apparent clearance (CL/F). For oxcarbazepine, as the number of trough concentrations per subject increased, the accuracy and precision of CL/F, between-subject variability (BSV) of CL/F and residual variability (RUV) tended to be improved. For tacrolimus, however, although no improvement were observed in the accuracy of CL/F and BSV of CL/F, the PE distribution ranges were significantly narrowed and the RUV estimates were less bias and imprecise. In terms of algorithm, Monte Carlo importance sampling (IMP) and IMP assisted by mode a posteriori estimation (IMPMAP) were consistently better than other methods. Additionally, the sampling design had no significant effects on the individual parameter estimates, which were only depended on the interaction between BSV and RUV in various algorithms. Decreased in BSV and RUV levels can improve the accuracy and precision of the estimation for both population and individual pharmacokinetic parameter estimates.
