Objective To study the the current situation of sexual for college students in luzhou area and to provide basis for their sexual health education .Methods 2 226 college students from four colleges in luzhou area were investigated by stratified clus-ter sampling method ,SPSS11 .5 software was used to analysis the results .Results 59 .62% of the students′knowledge was mainly from the media ,the test for sexual knowledge of college students′was satisfactory ;58 .94% of college students would like to com-municate and communication about sex and love ,84 .61% of the students thought that college students should have correct love and chastity view ,82 .95% of the students thought that should make efforts to prevent venereal disease and AIDS ,55 .27% of the students were firmly opposed to marriy during school study ;75 .15% of the students were firmly opposed to premarital sexual be-havior ,44 .44% of the students minded that lover once had sex ,36 .56% of the students broken up immediately when found that loveer had sex before .Conclusion The college students′sexual maturity in advance but knowledge of sex education relative lag , making them for many sexual problems and phenomena ,so scientific and systematic sexual health education should be strengthen in students .

Magnetic resonance imaging(MRI) has multi-faceted advantages due to its non-ionization radiation, excellent tissue contrast, high spatial resolution and multi-dimensional imaging technique. It can clearly observe the pathological changes of deseases, and judge for the prognosis. With the development of MRI, MRI has become increasingly popular in the diagnosis of fetal malformation. In this paper, it is described the value of MRd in the diagnosis, management and prognosis of fetuses malformations, via the central nervous system, circulatory system, respiratory system, digestive system, genitourinary system, musculoskeletal system, endocrine system, and so on.

Establishment of bioassay methods is the technical issues to be faced with in the bioassay of Chinese materia medica. Taking the bioassay of Coptis chinensis Franch. as an example, the establishment process and application of the bioassay methods (including bio-potency and bio-activity fingerprint) were explained from the aspects of methodology, principle of selection, experimental design, method confirmation and data analysis. The common technologies were extracted and formed with the above aspects, so as to provide technical support for constructing pattern and method of the quality control for Chinese materia medica based on the dao-di herbs and bioassay.

OBJECTIVE:To investigate the status quo and tendency of the utilization of drug for bony metastasis cancer in our hospital. METHODS:The utilization of drug for bony metastasis cancer in our hospital from 2006 to 2009 was analyzed statistically. RESULTS:The total amount of the drug for bony metastasis cancer had been increasing. Pamidronate took up the first place of the consumption sum list and accounted for 80% of total consumption sum. Top one drug in the list of DDDs was domestical pamidronate. Utilization rate of disodium clodronate increased form 0.67% in 2006 to 31.68% in 2009. The order of DDC had not changed during 2006～2009. CONCLUSION:In recent year the drug for bony metastasis cancer has been rational and has become curative effect-oriented rather than price-oriented.

Objective To explore the myocardial damage and the changes of MB isoenzyme of creatine kinase(CK-MB) and cardial troponin I(cTnI) of rat with endotoxemia at early stage.Methods Sixty SD rats were randomly divided into lipopolysaccharide(LPS) group(LPS group,n=48) and control group(n=12).Rats in LPS group were injected intraperitoneally with LPS(5 mg/kg) and then divided into 6 subgroups according sacrificed time after injection(0.5,1.0,2.0,3.0,12.0,24.0 h).CK-MB/ cTnI in blood was determined with chemiluminescent technique and myocardial pathological damage was observed under the light and transmission electron microscope.Control group was subjected to normal sodium and divided randomly into the same subgroups too.Results The rat diminished their action after beening injected endotoxin 15 minutes,and their reaction were slow.One hour later,they were short of action and reaction.Three hours later,they almost did not move at all,and the glossiness of their pelage were faint.Twenty-four hours later,their foodintake was diminished,their shout were weakened,and their response to stimulus were very thin,the glossiness of pelage were insufficient.Compared with control group,CK-MB increased significantly at 1.0,2.0,3.0,12.0,24.0 h(Pa

Objective To investigate the effect of penehyclidine (PHCD) pretreatment on Toll-like receptor 4 (TLR4) mRNA expression in the lung following acute lung injury (ALI) induced by hemorrhagic shock in rats. Methods Forty healthy SD rats of both sexes weighing 200-250 g were randomly divided into 5 groups( n = 8 each): group Ⅰ sham operation (group S); group Ⅱ ALI (group ALI); group Ⅲ, Ⅴ, PHCD 0.3,1.0, 3.0 mg/kg were given iv respectively at 30 min before hemorrhagic shock (P1-3). Hemorrhagic shock was induced by exsanguinations. MAP was maintained at 35-45 mm Hg for 60 min. The animals were killed at 4 h after resuscitation. Their lungs were removed for microscopic examination, W/D lung weight ratio and determination of TLR4 mRNA expression in the lung tissue (by RT-PCR). NF-κB p65 protein expression in the lung tissue was determined (by immuno-histochemical staining). Results Hemorrhagic shock significantly increased TLR4 mRNA and NF-κB p65 protein expression in the lung tissue and W/D lung weight ratio. Pretreatment with PHCD 1.0 or 3.0 mg/kg significantly inhibited hemorrhagic shock-induced increase in TLR4 mRNA and NF-κB p65 protein expression in the lung and W/D lung weight ratio. The lung injury was significantly ameliorated in group P2,3 as compared to group ALI. Conclusion PHCD pretreatment can attenuate ALI induced by hemorrhagic shock through down-regulation of TLR4 mRNA expression and decreasing NF-κB activity in the lung.

Objective To investigate the discharge outcome and its clinical influential factors of acute poisoning in children, and to provide the clinical references for prevention. Methods Questionaire about acute poisoning in children made by the research group,the hospitalized children and the influential factors were analyzed according to the outcome. Results Among 168 cases of acute poisoning hospitalized children,the curative rate was 80.95%, 16 cases(9.52%) were improved,6 cases (3.57%)were quitted,1.20% was ' not curative' and 4. 76% died. The factors including age,treatment time, route of entry, varieties of poison, medical examination of admission were statistically associated with the discharge outcome.Conclusion The outcome can be improved through an intensive nurse of the children under the age of three and early treatment. The cases who were not poisoned by the invasion of gastrointestinal tract,paraquat poisoning,and those with abnormalities of breathing, pupilla, awareness in medical examination of admission would have poor discharge outcomes, and should be monitored closely and treated timely.
