Objective To observe the effects of asthmatic children treated by inhaled salmeterol xinafoate and fluticasone propi-onate powder. Methods One hundred and fourty cases of moderate and severe asthmatic children were treated in non- acute period aged from 4 to 14 years by inhaling salmeterol xinafoate and fluticasone propionate powder, compared with control group treated by flu-ticasone propionate in 106 cases, and the pulmonary function was monitored simultaneously. Results The total effective rate of the treatment group and control group were 99. 3 % , 99. 1 % , respectively.The pulmonary function indexes such as the first one second expiration volume(FEV1), flow velocity of 50 % expiration vital capacity(FEF50%), peak expiration velocity(PEF1) after being treated 4 months was improved significantly compared with those before treatment.The difference between them was statistically significant (P

Atropa belladonna is a medicinal plant and main commercial source of tropane alkaloids (TAs) including scopolamine and hyoscyamine, which are anticholine drugs widely used clinically. Based on the high throughput transcriptome sequencing results, the digital expression patterns of UniGenes representing 9 structural genes (ODC, ADC, AIH, CPA, SPDS, PMT, CYP80F1, H6H, TRII) involved in TAs biosynthesis were constructed, and simultaneously expression analysis of 4 released genes in NCBI (PMT, CYP80F1, H6H, TRII) for verification was performed using qPCR, as well as the TAs contents detection in 8 different tissues. Digital expression patterns results suggested that the 4 genes including ODC, ADC, AIH and CPA involved in the upstream pathway of TAs, and the 2 branch pathway genes including SPDS and TRII were found to be expressed in all the detected tissues with high expression level in secondary root. While the 3 TAs-pathway-specific genes including PMT, CYP80F1, H6H were only expressed in secondary roots and primary roots, mainly in secondary roots. The qPCR detection results of PMT, CYP80F1 and H6H were consistent with the digital expression patterns, but their expression levels in primary root were too low to be detected. The highest content of hyoscyamine was found in tender stems (3.364 mg x g(-1)), followed by tender leaves (1.526 mg x g(-1)), roots (1.598 mg x g(-1)), young fruits (1.271 mg x g(-1)) and fruit sepals (1.413 mg x g(-1)). The highest content of scopolamine was detected in fruit sepals (1.003 mg x g(-1)), then followed by tender stems (0.600 mg x g(-1)) and tender leaves (0.601 mg x g(-1)). Both old stems and old leaves had the lowest content of hyoscyamine and scopolamine. The gene expression profile and TAs accumulation indicated that TAs in Atropa belladonna were mainly biosynthesized in secondary root, and then transported and deposited in tender aerial parts. Screening Atropa belladonna secondary root transcriptome database will facilitate unveiling the unknown enzymatic reactions and the mechanisms of transcriptional control.

BACKGROUNDCD44v6 plays an important role in invasion and metastasis of tumor, Livin has anti-apoptotic effects. The present study aimed to explore the expression and clinical significance of CD44v6 and Livin in gastric cancer tissue.

METHODSStreptavidin-peroxidase linked immunohistochemical method was used to determine the expression of CD44v6 and Livin in gastric cancer tissue and adjacent normal gastric tissues from 59 patients with histopathologically confirmed gastric cancer, and in gastric tissue specimens of 15 patients with gastric polyps, and 15 patients with chronic non-atrophic gastritis. The chi-square test was used for comparison of the relevant factors, Spearman's rank correlation test was applied for relationship among positive expression of the proteins.

RESULTSThe expresion of CD44v6 was positive in 64.4% of the gastric cancer patients; 5.1%, 0 and 13.3% in specimens of normal tissues adjacent to the cancer tissues, in gastric tissue specimens of patients with gastric polyps, and patients with chronic non-atrophic gastritis, respectively. The expression of Livin was positive in 52.5% of the gastric cancer tissues, 6.8%, 0 and 6.7% in the adjacent normal gastric tissue, specimens of patients with gastric polyps and chronic non-atrophic gastritis, respectively. The expression of CD44v6 was significantly correlated with the depth of invasion, the degree of differentiation, and lymphnode metastasis of gastric cancer (P < 0.05). The positive expression rate of Livin protein was also significantly correlated with degree of differentiation of gastric cancer cells and metastasis to lymphnodes (P < 0.05), but not correlated with the depth of invasion and pathological types (P > 0.05). The expression of CD44v6 and Livin in the gastric cancer tissue was positively correlated (r(s) = 0.286, P = 0.028).

CONCLUSIONSThe increased expression of CD44v6 and Livin in gastric cancer tissue may be closely related with development and progression of gastric cancer. CD44v6 and Livin may be new biological markers of gastric cancer.

This study was purposed to detect the expression of transforming growth factor β1 (TGF-β1) and its receptors (TGF-βR) and to investigate their roles in pathogenesis of immune thrombocytopenic purpura (ITP). The expressions of TGF-β1 and their receptors TGF-βRI, TGF-βRII and TGF-βRIII in the peripheral blood of patients with ITP and healthy persons were detected by the real-time PCR, and differences of their expression levels were analysed. The results showed that the expression of TGF-β1 and TGF-βRII mRNA in ITP patients was significantly higher than that in the healthy controls, while the TGF-βRI mRNA expression in ITP patient was significantly lower than that in the controls. The expression of TGF-βRIII was not statistically different between the two groups. It is concluded that TGF-β1 and its receptors including TGF-βRI and TGF-βRII express abnormally in the peripheral blood of ITP patients, which suggests that the TGF-β signaling pathway probably play a vital role in the pathogenesis of the ITP.

OBJECTIVETo investigate the effect of early intervention by pravastatin with two different dosage on inflammatory factors and endothelial vasodilator function in patients with unstable angina (UA).

METHODS108 patients with UA were investigated consecutively and divided randomly into three groups (group 20 mg, n = 37; group 10 mg, n = 37; group control, n = 34). Blood samples were examined at admission and 4, 8 weeks after the therapy of pravastatin. Fourty patients of UA were chosen from those three groups (15, 15 and 10 cases respectively). The endothelium-dependent vasodilation and the function of vascular endothelium of them were measured. In the dosage of 20 mg pravastatin group non-endothelium-dependent vasodilation in brachial artery was also tested by ultrasound before and 8 weeks after the therapy. Cardiac events were followed up for 2 months.

RESULTS(1) The use of pravastatin in early admission period of UA could significantly reduce inflammatory factors and improve vascular endothelium function, which was more obviously in the group of 20 mg/d than in group of 10 mg/d. These benefits occurred in 4th week and more obviously in 8th week after the therapy. (2) The lipid lowering therapy in the early stage of admission (24 - 48 h) resulted in the reduction of cardiac events in the hospital.

CONCLUSIONThe use of pravastatin 20 mg/d seems better than that of 10 mg/d in all the fields as above in early admission period of UA patients.

OBJECTIVETo investigate the evolution pattern of the Runx3 gene 5'-CpG island ~3478 bp region methylation in human salivary gland adenoid cystic carcinoma (SGACC).

METHODSQuantitative MSP method was used to detect the methylation status of CpG island in various regions (No.1-10) of Runx3 promoter region, and Western blot was used for detection of the expression of Runx3 protein in 41 salivary gland SGACC samples and corresponding non-neoplastic salivary gland tissues. A Logistic model was used to analyze the risk ratio between the methylation status of CpG island in Runx3 gene and development of salivary SGACC, meanwhile, the possible association among the methylation of Runx3 gene, the clinicopathological parameters of SGACCs, and Runx3 protein expression was compared.

RESULTSThe results of qMSP showed that the hypermethylation initially occurred at the most 5' region of the Runx3 CpG island and spread to the transcription start site. The methylation rate was highest in region No. 1 and No. 2 among the successive ten regions ranging from the 5' region to the transcription start site within the Runx3 CpG island, and lowest in the transcription start site both in SGACCs and normal salivary glands. Furthermore, there was no methylation in the transcription start site in nomal salivary glands tissues. Together with the results of Logistic model analysis, those results indicate that the transcription start site within the Runx3 promoter CpG island is critical for gene silencing. Western blot results revealed that the Runx3 protein level in SGACC was significantly lower than that in normal salivary glands (P < 0.01). In combination of the results of qMSP, it is presumed that the Runx3 gene methylation is one of the reason inducing the down-regulation of Runx3 in SGACCs.

CONCLUSIONSMethylation of the Runx3 CpG island spreads from the most 5'-region to the transcription start site in human salivary gland adenoid cystic carcinoma, and the transcription start site may be a critical region for the methylation of Runx3. The evolution pattern of Runx3 gene methylation is related to the tumorigenesis of SGACCs.
