Methods SARS virus BJ 01 strain in various dilutions was inoculated to Vero E6 cells, the cells were then covered with nutritious agar. The titers of the plaque were measured by Dullbecco R method. Results The plaque of SARS virus appeared on the third day after the cell cultures infected with virus. The plaque was round in shape, 2.5-3 mm in diameter. Conclusion The plaque assay developed in present study was stable and regular, and it could be used in SARS research.

ObjectiveTo observe whether if intravenous infusion of dexmedetomidine in advance can prevent irritation and cough causing by sufentanil.MethodsNinety patients who performed excision of intracranial tumor were divided into observation group and control group by random digits table with 45 cases each.Patients in observation group were intravenously infused 0.5 μg/kg dexmedetomidine for 10 minutes before induction.Patients in control group were intravenously infused 0.9％ sodium chloride for 10 minutes before induction.All the patients were intravenously infused 0.3 μg/kg sufentanil after taking drugs of load dosage in 3 seconds,and the incidence of irritation and cough in 1 minute was observed.The mean arterial pressure and heart rate were recorded before infusing dexmedetomidine or sodium chloride(T0),at the end of infusing dexmedetomidine or sodium chloride (T1),before intubation (T2),1 minute after intubation (T3).ResultsThe incidence of irritation and cough,moderate-severe irritation and cough in observation group [ 24.4％ ( 11/45 ),11.1％ (5/45) ] were lower than those in control group [ 48.9％ (22/45),22.2％ ( 10/45 ) ]with significant differences(P＜ 0.01 ).The mean arterial pressure in control group at T2 was lower than that in observation group [ (71.2 ± 3.5) mm Hg( 1 mm Hg =0.133 kPa) vs.(84.7 ± 4.1 ) mm Hg] with significant difference (P ＜ 0.05 ).The mean arterial pressure in control group at T3 was higher than that in observation group [(96.7 ± 6.4) mm Hg vs.(83.1 ± 5.2) mm Hg] with significant difference(P＜ 0.05).The heart rate at T1,T2,T3 in observation group was lower than that in control group [ (53.2 ± 4.7 ) beats/min vs.(70.4 ± 6.2 )beats/min,(56.3 ± 3.1 ) beats/min vs. (64.7 ± 3.7) beats/min,(59.1 ± 4.8) beats/min vs. (81.5 ± 6.1 )beats/min],and there were significant differences(P ＜0.05).Conclusions Intravenous infusion of dexmedetomidine (0.5 μg/kg) in advance can effectively prevent irritation and cough causing by sufentanil,and can enhance the stability of circulation during intubation.

In order to promote the optional subjects' function in perfecting knowledge structure and developing students'personalities,through analyses of the results of 830 classmates' selection of optional subjects,we know in detail the contents,objective and the factors for which students hope to increase and select optional subjects.Thus suggestions for enhancing the construction and management of optional subjects have been put forward: transforming conception,nailing down the study purpose,increasing optional subjects and establishing the leading teachers' system of optional subjects.

The aim of this study was to evaluate the effects of compound probiotics on milk performance,blood biochemical indexes,rumen fermentation parameters and nutrient digestibility of Holstein dairy cows in middle-and-later lactation.Forty-eight dairy cows with similar milk yield,days in milk and age were randomly divided into 4 groups treated with four different levels of compound probiotics as follows:the control group (0 g/d),group 1 (10 g/d),group 2 (20 g/d) and group 3 (30 g/d).The adaptation period was 7 days,and the total experimental period was 60 days.Results showed that:compared with the control group,supplementation of compound probiotics could improve milk yield and significantly increase the concentration of milk protein,lactose and total solids (P＜0.05);there was no significant effect on blood biochemical indexes (P＞ 0.05);compound probiotics could significantly increase the content of ammonia and microbial protein content (MCP) in the rumen (P＜ 0.05);the apparent nutrient digestibility of crude protein and crude fat of group 2 was significantly higher than other groups (P＜0.05);compared with the control group,the economic benefits of group 1,2,3 increased 2.28,4.80 and 4.09 yuan/d,respectively.In summary,dietary supplementation with 20 g/d of compound probiotics was the most effective method for milk performance,rumen fermentation parameters,nutrients apparent digestibility and economic benefit of Holstein dairy cows.

Objective To examine the relationships between a number of potential risk or protective factors and the risk of depression and anxiety among a population of adolescent elite athletes in Guangzhou city. Methods A whole sample was consisted of 520 students,and the information of their age,gender,characteristics and others was investigated. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scales(HADS). Data were analyzed using multiple stepwise regression analysis. Results After adjusting for other variables,students who had a high risk of anxiety were underweight (sβ =2.482) when compared to those who were of normal weight. Reduced risk of anxiety was associated with older students ( sβ = 4. 365), students with moderate educated mothersβ=3. 153) , and students who perceived very high pressure from teachers/coaches (sβ=5.372). A significant increase in the risk of depression was associated with variables including: students aged between 15 and 16 years(sβ =3.367) ,students who had a family history of chronic diseases (sβ =2.765) , and poor overall support(sβ = 4.365). Reduced risk of depression was associated with students with moderate educated mothers( sβ = 6.764) and students who perceived very high pressure from teachers/coaches(sβ = 4. 167). Conclusion Various risk and protective factors have been identified for anxiety and depression. These results have direct implications on the development of appropriate preventive strategies for mental problems among young elite athletes.

Results The rate of low cleanliness samples (stage Ⅲ + Ⅳ) was significantly higher than that of StageⅠ + Ⅱsamples .Of the 2 533 cases ,the detection rates of fungus and small gram negative or gram variable rods were significantly higher among specific patho‐gens and pathogenic bacteria ,respectively .The rates of low cleanliness samples were highest at age below 20 and in the season of winter (81 .3% ,73 .0% ) ,those of fungus at age from 21 to 30 and in the season of summer (23 .9% ,23 .0% ) ,and those of small gram negative or gram variable rods at age from 31 to 40 and in the season of winter (25 .1% ,37 .3% ) .In comparison with golden method ,the sensitivity and specificity of BV BLUETM method were 80 .0% and 90 .0% ,which reflected the accuracy was 87 .5% . Conclusion Vaginal infection of a hospital women was more common in young group and in the season of winter .Fungus and small gram negative or gram variable rods were the major pathogens .BV BLUETM method could assist in the BV rapid diagnosis ,with potential false positive/negative results being fully validated .

Objective To measure the organ weights , physiological and biochemical parameters and immune cells of NOD/SCID mice.Methods Mice at five and ten weeks of age were selected .The organ weights, blood physiological and biochemical parameters were observed .The percentages of CD 3+, CD4+, CD8+, CD19+, B220+, NK1.1+, and CD11b+were checked by FCM in NOD/SCID mice at six week of age in terms of its T , B lymphocyte function and NK cell activity.Results Among the same sex group of NOD/SCID mice, the weights of kidney, liver, heart and lung, and the blood physiological indexes of RBC , HGB, HCT, MCV, MCH, RDW, and the blood biochemical indexes of TP , ALB, ALP, CHO, TBIL show significant difference between 5 and 10 weeks.At the same age, HCT, GLOB, A/G, CHO, TG, TBIL and the UN are significantly different between male and female NOD /SCID mice.NOD/SCID mice lack T cells (0.37 ±0.26)%、CD4+T cells (0.35 ±0.13)%、CD8 +T cells (0.47 ±0.10)%、CD19+B cells (0.13 ± 0.05)%、B220+B cells (1.20 ±0.44)%.The percentage of NK cells is (6.90 ±0.82)%, and the percentage of granulocytes is (47.88 ±15.54)%.Conclusions The study indicates that NOD/SCID mice show the deficiency of T , B and NK cells function .The organ weights , blood physiological and biochemical parameters are affected by age and gender . The studied parameters of NOD/SCID mice are similar with the same strain in other countries .
