The accurate medical treatment is based on the information of the genome, which is the best treatment for the patients. Population pharmacokinetic study can be formulated according to the individual differences of patients to the dose, in the accurate medical model which has a unique advantage. At present, there are many problems such as adverse drug reaction in Chinese traditional medicine, and it is necessary to introduce a group of medicine on the basis of precise medical treatment. However, due to the different characteristics of traditional Chinese medicine and chemical medicine, it is necessary to combine the population pharmacokinetics, genetics and statistical methods to establish a research method which is in line with the characteristics of Chinese medicine. The key scientific problem is to make clear the active components of Chinese medicine metabolism of the drug metabolic enzyme gene, and pay attention to the analysis of the polymorphism of the overall role of drug metabolism enzymes in the human body. Clear key scientific issues and break through the bottleneck, so as to achieve the precise medical treatment, to international.

To investigate the inhibitory effects of RNAi expression vector on CaMKⅡ? expression of PC12 cell lines. siRNA expression vectors were constructed to be targeted directly at CaMKⅡ? gene. The recombinants were transfected into PC12 cell line with liposome. The expression of CaMKⅡ? was detected by RT-PCR and Western blot. Expression vectors could reduce the expressions of CaMKⅡ? mRNA and protein in PC12, Compared with blank vector group, the former, the ratio of inhibition of the expression of CaMKⅡ? mRNA was 46.40% and 64.69%, in 48th hour and 72th hour, the ratio of inhibitory of the expression of CaMKⅡ? protein was 74.77% in 72th hour. RNAi expression vectors can effectively inhibit the expression of CaMKⅡ? in PC12.

Objective To investigate the effect of intrathecal(IT)different concentrations of ozone(O_3) on pain threshold,motor function and cerebral spinal fluid(CSF)malondialdehyde(MDA)concentration and superoxide dismutase(SOD)activity and determine if ozone is toxic to central nervous system(CNS).Methods Thirty New Zealand white rabbits of both sexes aged 3-5 months,weighing 2.5-3.0 kg were randomly divided in 5 groups(n=6 each):groupⅠcontrol;groupⅡpure O_2;groupⅢO_2-O_3 30;groupⅣO_2-O_3 50 and groupⅤO_2-O_3 80.The animals were anesthetized with intraperitoneal pentobarbital.Cerebello-medullary cistern was punctured for IT administration of O_2 and O_3.In groupⅡ2 ml of pure oxygen(O_2)(for medical use)was injected IT.In groupⅢ,ⅣandⅤ2 ml of ozone(O_3)30,50 and 80 mg?L~(-1) was injected IT respectively.Ozone was manufactured by ozone generator(Ozoneline Co,Italy).Before and one day after IT O_3 paw withdrawal latency to heat(PWHL)and to mechanical stimulation(yon Frey filament)(PWML)were measured and motor function was assessed(1=normal,4=severe motor dysfunction and weakness).CSF was obtained at 1,2,4 h after IT O_3 for determination of MDA concentration and SOD activity.Results IT administration of the 3 concentrations of ozone did not affect pain threshold and motor function,but significantly increased SOD activity.MDA concentration decreased significantly at 4 h after IT O_2 or ozone administration in groupⅡ,ⅢandⅣ,but increased significantly at 1 and 2 h after IT ozone in groupⅤ.SOD/MDA was significantly increased at 1,2 and 4h after IT ozone in groupⅢandⅣ,but decreased at 1 and 2 h after IT ozone in groupⅤ.Conclusion IT ozone is toxic to CNS.

More than ten bacteriophage of E.coli were isolated from the soil and the dung of the fowl-run, then three of named bacteriophage A, C, D which lysis E.coli virulently were selected to investigate biological characterizations. The results showed that high activities were obtained after the phages incubated at 50℃ for 1 h or 60℃ for 30 min. The phages could be alive at the range of pH from 4 to 12, Ca 2+ or Mg 2+ added to the medium could stimulate the lysis of phages. However, the formation of the plaque could be inhibited obviously by adding sodium citrate to the medium.

Objective To understand the sleeping time and the prevalence of sleep disturbances in children aged 3-12 years in Wuxi city.Methods Two thousand and three hundred seventy six children aged 3-12 years were investigated with questionnaires from June to September 2003.Results The average sleep time of 1 day in each age group was 11.61,10.91,10.68,10.27,9.81, 9.67,9.61,9.57,9.60,9.61 hours, respectively. The total prevalence of sleep disturbance was 25.5%. Among them, the sleep snoring prevalence was 7.8%; choke/gargling was 0.63%;mouth breathing was 6.6%;sleep apnea was 0.34%;rubbing teeth was 7.7%;sleep talking was 4.2%;somnambulate was 0.63%;enuresis was 1.4%;limber spasm was 3.2%;sleep inquietude was 6.2%。Conclusion Prevalence of sleep disturbance in children age 3-12 years was high and sleep time was shorter in Wuxi than that in other cities.

A novel disposable three electrodes blood alcohol biosensor strip was fabricated by a screen printing technique. Multi-wall carbon nanotube(MWCNT), Meldola′s(MB), alcohol dehydrogenase(ADH)and nicotinamide adenine dinucleotide cofactor (NAD+) were modified on the surface of the carbon working electrode. Then hydrophilic membrane was stuck in the outermost of the three electrodes to make a reaction camera of 5 μL. Experimental results indicated that the biosensor possessed good accuracy and stability, the linear response range was 0.5-20 mmol/L with correlation coefficient of 0.9949, detection limit was 0.22 mmol/L, and the response time was less than 15 s. Some influencing factors to the biosensor were investigated, such as the pH, temperature and interferences. Correlation analysis showed that there was a significant correlation between the methods of biosensor and the headspace vapor phase chromatography in 10 whole blood samples(r=0.97583). Small volume whole blood sucked using siphonage to detect blood alcohol directly and quantitatively was the obvious character of the biosensor.

AlM:To find better ways of treating ocular alkali burn, and to reduce the suffering of patients and social burden.METHODS:Totally 100 patients were graded according to the degree of chemical burns to four major groups, each half were randomly divided into the control group and the treatment group. Control group underwent conventional treatment. ln addition to conventional therapy, patients in each treatment group were also added a Breviscapine intravenous injection of 40mg daily. Corneal recovery time, changes in vision, degree of corneal opacity, number of corneal neovascularization and other complications were observed. Curative effects were analyzed statistically.
RESULTS:There was no significant difference in levelⅠgroup between control group and treatment group ( P>0. 05); There were significantly different in level Ⅱ, Ⅲand Ⅳ group ( P<0. 05 ). Compared to the degree of corneal opacity and the number of corneal neovascularization, the treatment group was obviously better than the control group(P<0. 05).
CONCLUSlON: Breviscapine in the treatment of ocular alkali burns can shorten the course of treatment, reduce corneal scarring, and improve vision.
