AIM:To investigate the effects of amnion epithelial cell ( AEC) suspension liquid on the biological behavior of the rabbit's corneal epithelium, combined with the in vitro and in vivo experiments. · METHODS: The rabbit's corneal epithelium were cultured in the lower chamber of transwell, and AEC suspension liquid was dropwised in the upper chamber. There was only culture medium in the upper chamber of the control group. The proliferation of rabbit's corneal epithelium was observed with CCK-8 automated colorimetry and the expression of PCNA was detected by immunocytochemistry. We used the scratch wound assay to detect the migration of corneal epithelial cell ( CEC ) . The in vivo models were established by placing a 10mm diameter corneal trephine in the center of the cornea, within 1mol/L NaOH for 1min. We divided those into three groups: treatment group of AEC suspension liquid eye drop, AEC suspension liquid subconjunctival injection and the control group without any treatment. Using the slit- lamp biomicroscope and fluorescence staining to observe the cornea per week. After 28d we took the eyeballs with the HE staining. The expression of VEGF was detected by immunohistochemistry. ·RESULTS: The activity of CEC with AEC treatment was much higher than the control group ( P< 0. 05 ). The expression of PCNA increased in AEC group (P<0. 05). And the migration of CEC in the AEC group was faster than the control one. In vivo, the inflammation of the corneal and the CNV of the AEC group were all significantly reduced compared with the control group (P<0. 05 ). There were less invasive cells and more ordered organization arrangement in ACE group observed by the HE staining. The expression of VEGF and mcp-1 in these two AEC treatment groups all significantly decreased compared with the control group (P<0. 05). ·CONCLUSION: AEC suspension liquid can promote the proliferation and migration of the rabbit's corneal epithelium. The potential of AEC suspension liquid as a therapy for acute corneal alkali burn.

OBJECTIVETo evaluate the effectiveness of a school-based smoking prevention and control intervention program among elementary school students.

METHODSThrough two phase cluster sampling, 566 pupils in grade 4 and grade 5 of two schools were assigned to intervention group and control group. One year comprehensive smoking intervention was conducted in the intervention group. The assessment was carried out through three questionnaires: pre- and post-intervention, 6-month after intervention.

RESULTSAfter one year intervention, pupils in the intervention group significantly improved their knowledge and attitudes related to tobacco use. The rate of attempting smoking decreased form 7.8% to 2.6% and the rate of passive smoking from 53.6% to 41.8%. The difference between the intervention and control groups was statistically significant. However, several index started to decline at 6-month follow up survey.

CONCLUSIONThe result demonstrated the effectiveness and feasibility of tobacco control in elementary school and the positive effect must be developed.

Objective To establish a method for studying molecular mechanism of Rhubarb inhibiting anti-Yersinia pesti based on DNA microarray.Methods A whole genome DN A microarray containing 4005 annotated genes of Yersiniapesti Was used.The minimal inhibitory concentration(MIC)of Rhubarb to Yersiniapestiwas determined by liquid dilution method.The gene expression profile of Yersinia pesti was performed after the exposure to Rhubarb at a concentration of 10×MIC for 30 minutes.The total RNA extracted and purified from Yersinia pesti Was reversely transfected to cDNA and labeled by Cy3-Cy5 dye.The labeled probes were hybridized to the microarray anti the results were obtained by a laser scanner and the microarray data was confirmed by real-time quantitative RT-PCR.Results The platform of the DNA microarray-based bacteria transcriptional profile was established.A total of 498 genes of Yersinia pesti changed significantly in response to Rhubarb.Among them.358 genes were up-regulated,140 down-reguated.Conclusions The whole genome DNA microarray can be used in the studying of molecular anti-Yersinia pesti mechanism of Rhubarb.

Objective To analyze the factors which influence the treatment compliance of hypertensive patients in health management. Methods Data of 6 325 hypertensive patients who received physical examination in our department were collected; 4 132 male cases and 2 193 female were included, their ages ranged from 28 to 84 years old;the average age was 61.2 ± 5.8 years. The patients of the health intervention group were randomly divided into 3 groups (group 1, group 2 and group 3). They were provided with regular health management (including weight management, catering management, sports management, medication management and monitoring of blood pressure), respectively, given different frequency of telephone follow-up (1 time per 2 months, 1 time per month, and 1 time per month), evaluating treatment compliance. All the results were analyzed and compared respectively according to the level of education, age and mental status. Data of 1 892 hypertensive patients who received outpatient services were enrolled as the control group. Among them, 4 132 were male and 2 193 were female, aged 28-84 years old, average (61.2 ± 5.8) years old. They received the traditional outpatient follow-up (outpatient service review and health education), their treatment compliance, timely correcting unhealthy lifestyle and medication method and self-testing blood pressure were evaluated. ANOVA and chi square test were used to analyze the treatment compliances and blood pressure control rates of the two groups. Result Compared with the control group, health intervention for hypertension patients could significantly improve the treatment compliance and blood pressure control rate(64.8%vs. 41.3%, 56.7%vs. 29.6%;χ2=2.827,1.382;P=0.032,0.007). Comparing the results of telephone follow-up frequency, the treatment compliance and blood pressure control rate of the 3 intervention groups were higher than those of the two other groups(77.3%vs. 65.4%, 51.7%,χ2=3.414,P=0.041;69.6% vs. 57.3%, 43.2%,χ2=2.763,P=0.028). The treatment compliance of patients with high education level was significantly higher than that of patients with low education level(68.7% vs. 59.1%, 46.4%,χ2=3.257,P=0.037;60.1%vs. 47.2%,32.8%,χ2=1.234,P=0.009). And the treatment compliance of patients with good mental state was significantly higher than that of patients with anxiety(Intervention group1:64.3%vs. 55.1%,41.9%,31.0%,χ2=2.257, P=0.016;59.4%vs.46.1%,20.9%,21.8%,χ2=3.34 5 P=0.021;Intervention group2:75.5%vs. 64.3%,51.8%,41.2%,χ2=2.932, P=0.030;68.3%vs.57.1%,39.2%, 32.1%,χ2=2.382, P=0.032;Intervention group3:86.5% vs.73.2%,62.6%,52.4%,χ2=2.435, P=0.026;75.2% vs. 68.0%,51.7%,43.3%,χ2=3.251, P=0.036). Conclusion More frequently follow-up can improve the treatment compliance and control rate of blood pressure in hypertensive patients;education, age and psychological condition are factors influencing treatment compliance in hypertensive patients.

The enantiomers separation of thirteen drugs collected in Ch.P2010 was performed on chiral stationary phase of cellulose ramification (chiralpak OD and chiralpak OJ) by high performance liquid chromatographic (HPLC) methods,which included ibuprofen (Cl),ketoprofen (C2),nitrendipine (C3),nimodipine (C4),felodipine (C5),omeprazole (C6),praziquantel (C7),propranolol hydrochloride (C8),atenolol (C9),sulpiride (C10),clenbuterol hydrochloride (C11),verapamil hydrochloride (C12),and chlorphenamine maleate (C13).The mobile phase consisted of isopropanol and n-hexane.The detection wavelength was set at 254 nm and the flow rate was 0.7 mL/min.The enantiomers separation of these thirteen racemates on chiralpak OD column and chiralpak OJ column was studied,while the effects of proportion of organic additives,alcohol displacer and temperature on the separation were studied.And the mechanism of some of racemates was discussed.The results indicated that thirteen chiral drugs could be separated on chiral stationary phase of cellulose ramification in normal phase chromatographic system.The chromatographic retention and resolution of enantiomers could be adjusted by factors including column temperature and the concentration of alcohol displacer and organic alkaline modifier in mobile phase.It was shown that the resolution was improved with reducing concentration of alcohol displacer.When concentration of organic alkaline modifier was 0.2％ (v/v),the resolution and the peak shape were fairly good.Most racemates mentioned above had better resolution at column temperature of 25 ℃.When racemates were separated,the temperature should be kept so as to obtain stable separation results.
