Objective To examine miRNA-31 expression in serum of children with airway allergic disease (asthma and allergic rhinitis) and determine the correlation with CD44.Methods The expression of miR-NA-31 and CD44 in serum of 26 children with acute asthma and allergic rhinitis and non-acute phase and 36 normal control children were determined by real-time reverse transcriptase polymerase chain reaction.Results The miRNA-31 was significantly overexpressed in serum of children with acute asthma and allergic rhinitis compared with non-acute phase and normal control children and significantly correlated with CD44.Conclusion The correlation between miRNA-31 and CD44, the aberrant expression of miRNA-31 may account for the occurrence and development of airway allergic diseases.

0.05) after non-fever limit (non-FL) dose and FL dose endotoxin (ET) was intravenously injected into rabbits. The increase of PGE_2 in CSF was not limited during the occurrence of ET FL. 2. Intracerebroventricular injection (ICV) of different dose of PGE_2 into rabbits induced dose-dependent fever, but there was no more rise in body temperature when the febrile response had reached a certain height. This is termed "PGE FL". 3. The concentration of cyclic adenosine-3′, 5′-monophosphate (cAMP)in CSF paralleled the fluctuation of temperature (r=0.9906, P

40 New Zealand white rabbits were used to observe the effect on the fever caused by ET (endotoxin) and EGTA [ethylene glycol bis-(?-aminoethylethylether)-N, N, N′, N′-tetraacetic acid] after ICV (intracerebroventricular) infusion of Tau and CaCl_2 into rabbits. The results showed that Tau ICV perfusion could inhibit the initial febrile response to ET and EGTA in rabbits (P0.05), which could be blocked by ICV infusion of CaCl_2. The authors suggested that Tau might increase the level of Ca~(++) in the hypothalamus and reduce Na~+/Ca~(++) ratio, then lower the fever.

Objective To evaluate the efficacy and safety of sodium aescinate for abdominal operation in general surgery.Methods A multicenter,prospective and open labeled trail was conducted.Data of 2001 patients in PPS group who had undergone either conventional treated (n =500) or sodium aescinate treated (n =1 501) for abdominal operation in general surgery were analyzed.In the sodium aescinate treated group,sodium aescinate was given by ivgtt 12 h before the surgery started,and 20 mg daily after the surgery for 6 days.Time to recovery of gastrointestinal sounds (TRGS),time to recovery of passage of gas (TRPG),and time to recovery of bowel movements (TRBM) were recorded to evaluate the bowl function recovery.The difference of incision edema was observed by the evaluate edema level.Results The TRGS of sodium aescinate treated group was significantly shorter than that of the conventional treated group,P ＜ 0.01.The TRPG of sodium aescinate treated group was significantly shorter than that of the conventional treated group,P ＜ 0.01.The TRBM of sodium aescinate treated group was significantly shorter than that of the conventional treated group,P ＜ 0.01.The incision edema of sodium aescinate treated group was better than that of conventional treated group.The rate of adverse event was low in the sodium aescinate treated group,phlebitis was the most common one,accounting for 0.66％.No serious adverse event happened.Conclusion Sodium aescinate is effective and safe in accelerating patients recovery in general surgery.

AIM: To investigate association between children interleukin 1?(-511) gene polymorphisms and susceptibility to febrile seizures. METHODS: Children were devided into two groups: those with febrile seizures (FS) and healthy control, FS group was also devided into family history group and non-family history group. Single nucleotide polymorphisms of IL-1?-511 gene in promoters were detected by PCR-RFLP among these groups. RESULTS: Genotypes for IL-1? promoter -511 (T-T, T-C, C-C) in total febrile seizures and healthy controls were not significantly differen. Genotype IL-1?-511(T-T) in family history patients is 46.2% ,which is much higher than those in non-family history group (10.3%) and healthy control group (5.7%). The genotype proportions for IL-1? promoter-511 in family history group were markedly different from those in non-family history patient group and control group (P

Objective To investigate neoplastic lesions in gastrointestinal tract treated by endoscop-ic mucosal resection (EMR). Methods The properties, extent and infiltrating depth of the neoplastic lesions in gastrointestinal tract were detected by chromoendoscopy, magnifying videoscopy and endoscopic ul-trasonograpy. The tumors in niucosa or its muscular layer including the early cancer, precancerous lesion, submucosal tumors, polyps in laterally development, large polyps with or without peduncle were removed by EMR or transparent plastic cap EMR. Results Thirty-one submucosal tumors and four early cancers (esoph-ageal cancer 2, cardiac carcinoma 1 , early colonic carcinoma 1 ) and moderate or severe gastric dysplasia 2 were treated by EMR or transparent plastic cap EMR, no recurrence happened within 3-18 months follow-up. Laterally spreaded 13 polyps and 21 subpedunculated or sessile typed large polyps were resected by the procedures of EMR and Endoscopic Piecemeal Mucosal Resection ( EPMR). Five (7. 04% ) cases were complicated with bleeding during the procedure, and cured under endoscopies. One patient with villus adenoma ( 1. 41% ) recurred three months after EMR. Conclusion Under the guidance of chromoendoscopy, magnifying videoscope and endoscopic ultrasoundgraphy, EMR is a safe and effective endoscopic therapy for early cancers, submucosal tumors and large polyps in gastrointestinal tract.

AIM: To identify and quantitative analysis gentiopicroside content in the extract of Violent gentian of Tibetan herbal medicine. METHODS: Application of HPLC-the electricity sprays fog-mass spectroscopy/mass spectroscopy(HPLC-ESI-MS/MS) and the technique of LC-DAD-UV,by contrast with the reservation time of the authentic gentiopicroside,the ultraviolet absorbed spectrum,the molecule~+,quickly identified the gentiopicroside in the extract of violent gentian.As to it's quantitative analyis we adopted the capillary HPLC methods,with the weight of authentic gentiopicroside for abscissa. RESULTS: MS showed that the methanol extract of violet gentian mainly had five peaks.the compound structure of first peak was gentiopicroside,molecule~+ 356.9,result showed that gentiopicroside in gentian was 1.97%. CONCLUSION: Gentiopicroside is the mainly component of violet Gentia.

Aim To investigate the the effect of ginsenosides of stem and leaf(GSL) on mouse fatty liver and its mechanism.Methods Mice were randomly divided into normal control group(NC,fed with normal diet) and model group(fed with high-fat diet).Twelve weeks later,when the establishment of experimental model of fatty liver was confirmed,the model mice were subdivided into 4 subgroups: HF group(fed continuously with high-fat deit),NT group(fed with normal deit),GSL1 group(fed with normal deit and treated intragastrically with GSL 50 mg?kg-1?d-1),GSL2 group(fed with normal deit and treated intragastrically with GSL 100 mg?kg-1?d-1).Mice in NC,HF and HT groups were given distilled water by gastric perfusion.Two weeks later,all mice were killed,and blood was collected for measuring serum TC,TG,HDL-C,LDL-C,ALT contents,liver tissue for determining hepatic TC,TG,MDA SOD levels.In addition,liver index and pathology were also observed.Expression of PPAR? and CYP2E1 mRNA in liver was examined by RT-PCR.Results In GSL2 group,GSL significantly reduced liver index,serum lipid,hepatic lipid and MDA contents,and elevated SOD activity.Moreover,GSL obviously improved pathological change,increased PPAR? mRNA and suppressed CYP2E1 mRNA levels in the liver.In NT group,hepatic lipid and MDA contents remained high and SOD activity is low,although liver histology somewhat improved.In GSL1 group the results were similar to those in NT group.Conclusions These results suggest that GSL might be effective in the treatment of hepatic adipose infiltration of mice.It may be associated with increasing PPAR? mRNA,then decreasing serum lipid and hepatic lipid;and inhibiting CYP2E1 mRNA expression in the liver,thus suppressing lipid peroxidation.
