To solve the problems occurring in Ophthalmologic clinical teaching,we made a detailed investigation on the idea,mode as well as the application of specific methods for ophthalmologic clinical teaching.Then we raised a further proposition compatible with the social environment in order to improve the efficiency and quality of ophthalmologic clinical teaching.

Objective To evaluate the effect of continuous adenosine infusion on mesentery microcirculation during cardiopulmonary resuscitation in rats with asphyxia. Methods Rat model of asphyxia was established in 22 healthy Wistar rats. The animals were then randomly divided into normal saline group (group A, n=10), epinephrine group (group B, n=6) and epinephrine plus adenosine group (group C, n=6). After a 3-min asphyxia without intervention, cardiopulmonary resuscitation (CPR) was started. The cardiac compression was carried out with an electric cardio-pulmonary resuscitation machine (200 times/min). Respiration was restored and maintained with a ventilator with tidal volume of 4ml, breathing rate 50times/min and FiO2 100%. After a 4-min CPR, rats in group A and group B were given normal saline and epinephrine (bolus of 90?g/kg) respectively, and in group C epinephrine (bolus of 90?g/kg) plus 70?g/kg adenosine were given. Electric defibrillation would be initiated if there was ventricular fibrillation. The reperfusion rate of mesentery arterioles and venules, diameter of blood vessels and relative blood velocity were observed. Results The reperfusion rate of mesentery arterioles and venules was significantly higher in group C than in group B (P

Objective:To observe the effect of the proteininhibitor of activated STAT 3 (PIAS3) on the proliferation and apopto-sis of U251 glioma cells after PIAS3 expression was inhibited by RNAi. Methods: Three RNAi expression vectorstargeting PIAS3 were constructed and transfected into CHG-5 cells by liposomein vitro. The most efficient RNAi vector was subsequently selected by examiningthe mRNA expressions of PIAS3 in the transfected cells by semi-quantitativeRT-PCR. The selected RNAi vector was then transfected into U251 cells. After 48h of transfection, the mRNA and protein expressions of PIAS3 in glioma cellswere examined by semi-quantitative RT-PCR and western blot. Apoptosis wasobserved by flow cytometry using a double-staining method with FITC-con-jugatedannexin V and PI. Flow cytometry was also applied in cell cycle assay. Results:RNAidownregulated the mRNA (P<0.01) and protein (P<0.01) expressionsof PIAS3 in transfected cells.RNAi promoted the resistance of U251 cells to apoptosisand subsequently al-tered the cell cycle. A high percentage of G2 phaseand a low percentage of Sphase were observed in U251 cells. Conclusion:The down-regulation of PIAS3arrested U251 cells in the G2 phase andinduced the resistance of U251 cells to apoptosis.

OBJECTIVE:To establish a method for simultaneous determination of valsartan and hydrochlorothiazide in Valsar-tan hydrochlorothiazide tablets. METHODS:UPLC was adopted. The determination was performed on Phenomenex C18 column with mobile phase consisted of [0.1% phosphoric acid solution-acetonitrile(95 : 5,V/V)]-[0.1% phosphoric acid solution-acetonitrile (5 : 95,V/V)](gradient elution)at the flow rate of 0.25 mL/min. The detection wavelength was set at 272 nm,and the column tem-perature was 35 ℃. The sample size was 1.5 μL. RESULTS:The linear range were 8.1-324.2 μg/mL for valsartan(r=0.9999)and 1.2-50.1 μg/mL for hydrochlorothiazide(r=0.9999). The limits of quantitation were 0.24,0.04 ng,and the limits of detection were 0.06,0.01 ng. RSDs of precision,stability and reproducibility tests were less than 2.0%;recoveries were 97.69%-100.35%for valsartan(RSD=1.03%,n=9)and 98.27%-100.60% for hydrochlorothiazide(RSD=0.83%,n=9). CONCLUSIONS:The method is simple,rapid and accurate,and can be used for the simultaneous determination of valsartan and hydrochlorothiazide in Valsartan hydrochlorothiazide tablets.

AIM: To investigate the effects of goat placenta immunoregulating factor(GPIF) on the expression of costimulatory molecules lineaged T cells in BALB/c mice.METHODS: Animal model for immunodeficiency made from BALB/c mice with whole-body irradiation by 5 Gy 60Co?-ray was applied for research.The immunosuppressive mice were injected with GPIF for seven days continuously.FACS was applied to analyze the rate of CD28+,CD152+,CD4+CD28+,CD8+CD28+,CD4+CD152+ and CD8+CD152+ cells in splenic lymphocytes and ELISA method was employed to measure the amount of IL-2 and IFN-? in serum of mice.RESULTS: GPIF increased the percentage of CD28+,CD4+CD28+ and CD8+CD28+ cells(P

Objective To investigate the role of inhaled corticosteroids (ICS) on transforming growth factor - ?1 (TGF - ?1 )of asthmatic remodeling model Methods One hundred and eight guinea pigs were divided into 3 groups randomly and equally: asthmatic group( A), therapeutic group(B), control group(C) Three groups were treated by ovalbumin, budesonide, normal saline respectively The lung tissue specimens were collected after the guinea pigs were killed; the expression of TGF- ?1 was determined Results The expressions of TGF-?1 in A, K and C groups were(41 83 ? 10. 45) %, (27. 22 ? 8. 09)% , (15. 36 ? 2. 64)% respectively at 12 weeks. It was statistically significant( P
