The objective of this article was to explore new channels of information transmission in public health emergencies.According to the requestments of information transmission in public health emergencies,the current situation and problems were analysed.To solve the problems,the authors put forward a number of constructive measures,and came to the conclusion that to strengthen the construction of the channels of information transmission is one of the fundamental ways of improving the efficiency of correct handling of public health emergencies.

For the diathermancy of the seawater is much bigger than that of the air, and the heat dispersed from the body exceeds the heat produced by the body, the heat would be lost immediately when people fell into the cold seawater. The temperature of people would drop instantly to frozen stiff. So it has great signification to rescue the people dropped into the cold water at once. This paper will introduce how to rescue, examine, stabilize, insulate, finally transport the patient to the hospital, and some things that should be paid attention to during the whole process.

Objective To explore the relations between UA and serum hs-CRP, the effects of early intervention with atovastatin on serum hs-CRP in patients with UA and its clinical significance in the early management of UA. Methods T 60 patients with UA (UA group),53 patients with stable angina (SA group) and 50 healthy controls (control group) were enrolled to the study. The serum hs-CRP levels were measured by particle enhanced immunoturbidimetric assay. UA group were randomly assigned to the atovastatin group and the routine group for a 4-week treatment immediately after admission. Selected coronary artery angiography was performed in 78 patients and 29 healthy controls with Judkin's technique. Results Baseline of hs-CRP in patients with UA was significantly higher than those in SA group and control group ( P

With the development in the diagnosis and treatment of urological diseases and im-provement of minimally invasive technology in recent years, some apparent diseases and concepts of new technology can't be mentioned in teaching practice including functional diseases of lower urinary tract, further discussion of prostatic cancer and minimally invasive technology, etc. We elaborated on the importances, teaching significances and key points of these teaching contents in order to improve the knowledge teaching system.

were obviously increased. Conclusion HIF-1α was successfully cloned. HIF-1α-pcDNA3.1 can be effectively transfected into MSCs with liposome-mediated method, which can result stable expression of HIF-1αin transfected MSCs.

Aim To investigate the angiogenic promoting effect of Morinda officinalis How oligosaccharides(MOO) in the ischemic myocardium of rats after acute myocardial infarction(AMI).Methods 40 male Wistar rats were established into AMI model successfully and were randomly divided into 5 groups equally, i. e. the low, medium and high doses of MOO groups, the Shexiangbaoxin group and the model group. They were treated with different doses of the water fraction of the ethanolic extract of Radix morinda officinalis (0.7, 1.4, 2.8 mg·kg~(-1) ·d~(-1)), suspension liquid of Shexiangbaoxin Pill(30 mg·kg~(-1) ·d~(-1)) and distilled water with the same volume respectively.Besides, a sham operated group with 10 rats was set up for control. All rats were sacrificed after 6-week-treatment.The Ⅷ coagulation factor, vascular endothelial growth factor(VEGF) and basic fibroblast growth factor(bFGF) protein in ischemic myocardium of rats in each group were detected by immunohistochemistry assay.The microvessel density(MVD) was calculated. Gray values of protein expression of VEGF and bFGF in ischemic myocardium were calculated and analyzed by image analysis system.Results The MVD, the gray values of VGF and bFGF were higher in the medium and high doses of MOO groups than those in the model group(P <0.05), but still lower than those in the Shexiangbaoxin group(P <0.05). The MVD and the gray values of VEGF among 3 doses of MOO groups showed significant differences (P <0.05).Significant differences of gray value of bFGF were observed between small and middle doses of MOO groups, also between small and large doses of groups(P <0.05).Conclusion MOO can obviously promote angiogenesis in the ischemic myocardium of the rats after AMI.And up-regulating expressions of VEGF and bFGF protein in the ischemic myocardium may act as one of its angiogenic promoting mechanisms.

This paper investigated contamination situation of Listeria monocytogenes(Lm). To compare dif- ferent selectivity enrichment broth for detectable effect of Lm and compare detectable effect in different samples by using different methods, furthermore, choose the best enrichment broth for specific food. One hundred and thirty five random samples from raw meat, aquatic product, fruit and vegetable, quick-frozen food in Baoding. Applied LB enrichment broth, EB enrichment broth, new modification FDA enrichment broth and Fraser enrichment broth before separated by PALCAM selective agar, then identified by interna- tional standard method after PCR. Results: Four methods showed that there were 23 Lm positive, detected 5 Lm by LB method, 6 Lm by Fraser method, 5 Lm by EB method and 7 Lm by new modification FDA method. The total detectable rate of four methods had no large specificity, but to specific kind of food was different.

Objective:To assess the prevalence of HIV primary drug resistance and drug resistance gene mutations among men who have sex with men (MSM).Methods:We searched eight electronic databases (CNKI,VIP,CBM,Wanfang Database,PubMed,Web of Knowledge,Springer,Medline) for the studies of HIV drug resistance relevant to MSM.Drug resistance and drug resistance mutations data were pooled and analyzed according to statistical test of homogeneity.Subgroups were further divided according to sample size,location,race,quality rating score,sampling time.Results:Forty-three studies were included in this Meta-analysis.The pooled rate of total to protease inhibitor (PI),nucleoside reverse transcriptase inhibitor(NRTI) or non-nucleoside reverse transcriptase inhibitor (NNRTI) were 10.21％ (95％ CI 8.65％ to12.03％),2.98％ (95％ CI 2.25％ to 3.93％),4.05％ (95％ CI 3.14％ to 5.21％),4.42％ (95％ CI 3.31％ to 5.88％),respectively.The pooled rates of PI major mutation,PI secondary mutations,NRTI mutations and NNRTI mutations were 0.55％ (95％ CI 0.38％ to 0.80％),1.31％ (95％ CI 0.98％ to 1.75％),0.85％ (95％ CI 0.51％ to 1.40％),1.19％ (95％ CI 0.70％ to 2.01％),0.79％ (95％ CI 0.55％ to 1.13％),1.73％ (95％ CI 1.21％ to 2.46％),0.86％ (95％ CI 0.61％ to 1.21％),2.24％ (95％ CI 1.77％ to 2.83％),respectively.Sample size,region,and race were heterogeneous sources;the rate of resistance mutations and gene mutation rate were different in different subgroups.Conclusion:The prevalence of primary drug resistance among MSM was high in Americas and Europe,and it was gradually increased in Asia.We should pay attention to the high incidence of PI secondary mutations.

Object To develop a new method of discriminating the principle components of Radix Paeoniae Rubra (RPR) from different areas, and to find the reason for forming high-quality of RPR in the place of the genuine. Methods Using Foruier transform infrared (FTIR) absorption spectrometry, the characteristic peaks of fingerprint infrared spectra of RPR samples from 18 habitats were recognized and compared. Results Frequency, intensity and shape of infrared absorption spectra were obviously different between wild and cultivated groups of RPR. The infrared absorption peaks of RPR in Duolun, a famous Chinese orthodox drug, were of distinct characteristics. Conclusion FTIR technique is first applied to rapid analysis of principle component of RPR from different areas. So an operable method in the quality control and discrimination of RPR in the place of the genuine is provided.

Objective To evaluate the role of curved-cutter-stapler in anus-preserving for low rectal cancer.Methods The clinical data of 32 patients with low rectal cancer from June 2007 to December 2008 who received low anterior resection and ultra low anterior resection by using curved-cutter-stapler were reviewed retrospectively.Results No operation death case,complete cutting and safe closure in all cases,one case was complicated with anastomotic leakage,and one case of rectovaginal fistula.Thirty patients were followed up 4 to 22 months after the operation,with an average time of 12.6 months,no hemorrhea of pelvic cavity and anastomotic stoma or anastomotic stenosis cases.Conclusion Curved-cutter-stapler has the advantages of complete cutting,safe closure and low complications,and easy being used in anus-preserving operation for low rectal cancer,which can increase the rate of anus-preserving.
