Objective: To observe the clinical effects of pediatric tuina plus Chinese medicine for exogenous fever in children. Methods: A total of 150 children withexogenous fever were randomly divided based on the random digital table into a control group (75 cases) and a treatment group (75 cases). The control group was treated with oral Xiao'er Chaigui Tuire Keli (<1 year old, 0.5 bag/time; 1-3 years old, 1 bag/time; 4-6 years old, 1.5 bags/time), 4 times/day. The treatment group was treated with pediatric tuina plus the intervention of the control group. The amount and usage of Chinese medicine were the same as those of the control group; tuina was conducted 1 time/day. The clinical effects and adverse reactions were observed after 3 d of treatment in both groups. The recurrence was observed within 7 d after the end of treatment. Results: The total effective rate was 92.0％ in the treatment group and 81.3％ in the control group. The difference between the two groups was statistically significant (P<0.05). There were no obvious adverse reactions in the two groups after treatment. The recurrence rate was 1.5％ in the treatment group and 13.1％ in the control group. The difference in the recurrence rate between the two groups was statistically significant (P<0.05). Conclusion: Pediatric tuina plus Chinese medicine is effective in treating children with exogenous fever.

Urine provides an alternative to blood plasma as a potential source of disease biomarkers. Exosomes was separated by ultracentrifuge at 200000 g in normal persons and non-small cell lung cancer (NSCLC) patients′ urine. For proteomic analysis of urinary exosome, 1D sodium dodecylsulfonate-polyacrylate gel electrophoresis(SDS-PAGE) was carries out and cut the gel 31 kDa-20 kDa bands in normal group and disease group′s. These gel blocks were subjected to in-gel trypsinization, and the extracted peptides were analyzed HPLC-CHIP-MS/MS. Approximately 24 unique proteins were identified in the UniProtKB/SWISS-PORT. The difference expression proteins were found in urinary exosome from NSCLC patients, including three fragment of the immunoglobulin kappa, two kinds of Ras related proteins, glutathione S-transferase A2, serum amyloid P-component precursor and phosphatidylethanolamine-binding protein 1.

Objective · To determine the expression of miRNA-7 in TWEAK-stimulated macrophages and their secreted exosomes;to investigate the role of exosomal miRNA-7 from TWEAK-stimulated macrophages in modulating the metastasis of epithelial ovarian cancer (EOC) cells.Methods · Real-time PCR analysis was used to determine the miRNA-7 expression in TWEAK-stimulated macrophages,their exosomes and recipient HO8910-PM cells.The activity of EGFR signaling pathway in HO8910-PM cells was detected by Western blotting analysis.AntagomiR-7 was used to downregulate the miRNA-7expressions in macrophage exosomes and then their effect on metastasis of HO8910-PM cells was examined by transwell assay.Results ·TWEAK increased the levels of miRNA-7 in macrophages and their secreted exosomes and also resulted in an elevated level of miRNA-7 in recipient HO8910-PM cells,which eventually reduced the activity of EGFR/AKT/ERK1/2 pathway.Pre-transfection of antagomiR-7 remarkably decreased the levels of miRNA-7 in macrophages,their secreted exosomes and the recipient EOC cells,with the enhancement of HO8910-PM metastasis.Conclusion · Exosomal miRNA-7 from TWEAK-stimulated macrophages plays a critical role in suppressing the metastasis of EOC cells by attenuation of EGFR signaling pathway.

The involvement of astrocytes and correlation between neuronal injury and astrocyte response were studied. Blockingmiddle cerebral artery and reperfusing o. 5～48 h, H-E staining, immunoccytochemistry single-and double-labeling, dotble label-ing combined with TUNEL and GFAP immunocytochemistry were used to investigate neuronal injury and astrocyte response.The is chemic area peaked at 24 h of reperfusion. The neurons presented irreversible degeneration at 6 h of reperfusion. At24 h,ischemic area in the preoptic area developed into infarcted area; astrocytes exhibited differential morphological features: reactive,malnourished and degenerative changes. At 48 h of reperfusion, the number of astrocytes began to go up. The astrocytes in is-chemic area didn't proliferate within 48 h. By contrast, a few astrocytes underwent apoptosis. In conclusion, these data indicatethat the reaction of astrocytes is closely connected with the extent of neuronal injuries. The reactive astrocytes imply that astro-cytes positively respond to the neuronal injuries, which might play a role in promoting neuronal survival.

Objective: To observe the expression of the G-protein-coupled-receptor 14 (GPR14), urotensinⅡreceptor, in the cardiovascular system and brain of SD rats. Methods: Semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the GPR14 mRNA. Results: In cardiovascular system, GPR14 mRNA was detected in the left ventricle, left atrium, thoratic aorta and carotid aorta. The highest level of expression was found in the left ventricle. In the brain, GPR14 mRNA was detected in cortex, hippocampus, hypothalamus and cerebellum, and higher level of expression was found in the cerebellum. Conclusion: GPR14 mRNA expression is found in the cardiovascular and neural tissues of tested rat, suggesting that urotensinⅡ may play an important role in cardiovasculature and central nervous activity.

Streptomyces sp. A048 was cultured in a complete medium to the last stage of log phase,the hyphae were washed and collected by centrifugation. Then the hyphae were inoculated in liquid medium for chitinase production using two-step fermentation. Activity of chitinase produced by two-step fermentation was 1.1 times higher than that from one-step fermentation,and ferment cycle was for 54 hours,which was 66 hours shorter than that of one-step fermentation. The hyphae and the powder of chitin were co-immobilizated and cultured in liquid medium for 36 hours,activity of chitinase was 1.8 times higher than that from one-step fermentation,and ferment cycle was 54h shorter than that of one-step fermentation. By adding 0.4% cellulose to two-step fermentation,activity of chitinase was 18.52 U/mL that was 4 times higher than that from the control and 10 times higher than that from one-step fermentation. Two step fermentation with chitin and cellulose may be the optimal fermentation process to produce Chitinase from Streptomyces sp. A048.

Objective To evaluate 18F-fluorodeoxyglucose (FDG) PET/CT in detecting occult malignancy in patients with suspected paraneoplastic neurological syndrome (PNS).Methods Twenty consecutive patients who underwent PET/CT scanning with the indication of suspected PNS were retrospectively reviewed.The gold standard of PNS was either cytology or clinical follow-up, and the final diagnosis was compared with PET/CT findings.Results Of the 20 patients, six were PNS.PET/CT detected nine cases.Six were true positive and three were false positive.The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of PET/CT were 100% (6/6), 78.57% (11/14), 85.00% (17/20),66.7% (6/9) and 100.00% ( 11/11 ) respectively.The treatment plan was modified based on the PET/CT results in 4 patients.Conclusions 18F-FDG PET/CT may play a role in detecting the underlying malignancy of PNS.It is also valuable in staging of the malignancy thus providing information for therapy decision making.
