[ ABSTRACT] AIM:To observed the correlation between Th17 cell level and the symptom severity and prognostic factors of chronic obstructive pulmonary disease ( COPD) , and to explore the clinical application value of Th17 cell level in assessing the prognosis of patients with COPD.METHODS:The patients with diagnosed COPD ( n=110) in our hospital during May 2013 to December 2014, and 40 healthy subjects were enrolled in the study.According to the Global Initiative for Chronic Obstructive Lung Disease ( GOLD) , the COPD patients were divided into group A ( low risk, less symptoms) , group B (low risk, more symptoms), group C (high risk, less symptoms) and group D (high risk, more symptoms), which were given inhaled corticosteroid/long-acting β2 agonist or corticosteroid/long-acting β2 agonist +long-acting anti-muscarinic agent treatment for 3 months.The proportion of Th17 cells, cytokines (IL-17 and IL-6), the COPD assessment test ( CAT) score, age, body mass index, pulmonary function and the times of acute exacerbation of COPD in previous 1 year were observed before and after treatment.The correlation analysis between the level of Th17 cells and other clinical characteristics was performed.RESULTS:Th17 cell, IL-17 and IL-6 levels in COPD group were significantly higher than those in control group (P<0.05).With the increase in the severity of COPD symptoms, Th17 cells, cytokines (IL-17 and IL-6) and CAT score in groups B and D were significantly higher than those in groups A and C (P<0.05).The univariate analysis showed that the levels of Th17 cells in groups B and D before treatment were positively correlated with the CAT score (P<0.05), which were negatively correlated with FEV1, FEV1%Pred, FVC and FVC%Pred.The levels of Th17 cells were not correlated with the CAT score, FEV1 , FEV1%Pred, FVC and FVC%Pred in groups A and C.The levels of Th17 cells after treatment were positively correlated with the CAT score, which were negatively correlated with FEV1 , FEV1%Pred, FVC and FVC%Pred (P<0.05).CONCLUSION:The peripheral Th17 cell level has a good correlation with IL-17, IL-6, CAT score and pulmonary function in COPD patients, suggesting a potential value to predict the symptom severity and prognosis of COPD.

The morbidity and mortality of gastric cancer stand in the first place among all kinds of malignant tumours in our country,the early diagnosis rate is still very low and the prognosis is unsatisfactory also.The expression of CD133 probably as a tumour stem cell marker is significantly higher in gastric cancer primary lesion than that in normal tissue and its higher expression corelates with the larger size of tumor,lymph node metastasis occurences and poorer prognosis.Meanwhile,the positive expression of CD133 may have some relationship with the angiogenesis,severer infiltration depth,worse differentiation degree and later TNM stage of gastric cancer.This paper aims at further recongnizing the specific expression of CD133 in gastric cancer primary lesion,both the relationship with initiating and clinical pathological features of gastric cancer,so as to bring a new research direction for early diagnosis and targeted therapy of stomach cancer.

Objective To investigate the relationship between X-ray manifestations of breast cancer,pathology and X-ray classification,in order to improve the diagnostic level of breast cancer.Methods X-ray findings of 114 cases of breast cancer were analysed retrospectively.All cases were comfirmed by operation and pathology. Results All cases were divided into five types,including the mass type(34 cases),mass with calcification type(27 cases),calcification type(28 cases),abnormality structure type(21 cases) and latency type(4 cases).Infiltraing duct cancer was a high incidence(61.4%) and the secondary was simple cancer(20.1%).Conclusion breast cancer of the mass type,mass with calcification type and calcification type are characteristic mammographic features.Mammography could get a clear diagnosis.The breast cancer of the abnormality structure type are not characteristic mammographic findings.The imaging diagnostic rate of breast cancer can obviously improve through recognizing its X-ray findings.

AIM: To set up population pharmacokinetics/pharmacodynamics (PPK/PD) model of valproate (VPA) in children with epilepsy in China, and promote reasonable use of antiepileptic drugs(AEDs)in clinical practice. METHODS: Sparse data of VPA serum concentrations from 246 pediatric children were collected. These patients were divided into three groups: PPK-Model group ([WTBX]n=146), to calculate PPK parameter values of VPA and set up a PPK model; PPK-Valid group ([WTBX]n=100), to valid the PPK model; and PPD group ([WTBX]n=69), to set up PPK/PD model. Based on the data of PPK-Model group and PPK-Valid group, a PPK model of VPA in children with epilepsy in China was successfully set up by using NONMEM software by ourselves. Now, using the data of 69 patients in PPD group who were on VPA monotherapy and this PPK model, we set up PPK/PD model by NONMEM software. Efficacy of epilepsy treatment was divided into 5 grades according to the percentage of seizure frequency decreased (PSFD%): grade 1: PSFD% was 100%; grade 2: PSFD% was 75%-100%; grade 3: PSFD% was 50%-75%; grade 4: PSFD% was 25%-50%; grade 5: PSFD% was less than 25%. The quantitive relationship between the VPA serum concentrations and the probability for its efficacy score was characterized by Logistic regression analysis with NONMEM. RESULTS: Logistic regression analysis showed that, VPA serum concentrations and the probability for its efficacy grades 5, 4, 3, 2, and 1 were (23 ?g?ml -1, 5, 50%), (30 ?g?ml -1, 4, 32.3%), (50 ?g?ml -1, 3, 26.3%), (65 ?g?ml -1, 2, 36.5%), (78 ?g?ml -1, 1, 50%), and (100 ?g?ml -1, 1, 84.2%)respectively. CONCLUSION: A PPK/PD model of VPA in children with epilepsy in China is successfully established by using NONMEM software, and the probability of efficacy grade for any concentration can be calculated. It will be valuable to facilitate individualized dosage regimen.

A series of 5-amino-2-( benzylthio ) thiazole-4-carboxamide derivatives were designed and synthesized to discover novel compounds with anti-tumor activity. Compounds DDO-5401-DDO-5416 were synthesized using 2-amino-2-cyanoacetamide as the start material. The structures of the synthesized compounds were confirmed by IR, 1 H NMR and ESI-MS. The in vitro anti-tumor activities of the synthesized compounds were determined by MTT assay in HCT116 , HepG2 , A549 , MDA-MB-231 and MCF-7 cell lines. Target compounds showed good anti-tumor activity especially in A549 cell line. SAR study showed that electron donating groups were more favorable than electron absorption ones. Compound DDO-5413 exhibited noteworthy activity in MDA-MB-231 and MCF-7 cell lines with IC50 value lower than the positive reference dasatinib. It suggested that DDO-5413 might be the candidate for further investigation.

Objective To explore the pathogenesis and diagnosis of chronic granulomatous disease. Methods Clinical features and laboratory examination results of a child with chronic granulomatous disease were retrospectively analyzed. Genome DNA was extracted from peripheral blood of the child and his parents. The high-throughput sequencing was performed by Illumina sequencing platform, using the Agilent SureSelect exome capture method. Results The child had recurrent infections along with liver enlargement and dysfunction. The anti-infection and symptomatic treatment were unsatisfactory. Gene sequencing analysis revealed a homozygous point mutation (c.7C?>?T, p.Gln3*) in CYBA gene. His mother had the same heterozygous mutation in this locus, and his father had a large fragment heterozygous deletions. No other candidate gene mutations were identiifed. Conclusions The diagnosis of chronic granulomatous disease is conifrmed in this child. It is caused by CYBA gene mutation.
