Objective To investigate the effect of pseudolaric acid B(PAB) on the expression of vascular endothelial growth factor (VEGF) in human hepatoma BEL-7402 cells. Methods BEL-7402 cells were cultured with PAB (0, 0.5, 1.0, 2.0, 4.0 and 8.0μmol · L-1) for 6 h and stained with 0.4%trypan blue. The cell viability was observed and calculated under the microscope. The cell proliferation was detected by WST-8 analysis. The expression of VEGF mRNA in BEL-7402 cells was detected using RT-PCR method. The expression of VEGF protein in BEL-7402 cells was detected using Western blot assay. Results There was no significant difference in the cell proliferation of BEL-7402 cells between different PAB treat-ment groups and control group. With the increased concentration of PAB, the expressions of VEGF mRNA were significantly decreased in different PAB treatment groups (1.90±0.02,1.31±0.03,0.86±0.04,0.60±0.03 and 0.34±0.02) compared with that of control group (2.53±0.07, P＜0.01). The expressions of VEGF protein were significantly decreased in different PAB treat-ment groups (2.60±0.09, 2.42±0.07, 1.85±0.05, 0.92±0.05 and 0.60±0.04) compared with that of control group (3.06±0.15, P＜0.01). Conclusion PAB can inhibit the expressions of VEGF mRNA and protein in BEL-7402 cells.

AlM:To observe the clinical efficacy of two types of scleral-fixated posterior chamber intraocular lens ( lOL ) combined intra-capsule lens extraction to treat cataract dislocation.
METHODS: After intra - capsule lens extraction of dislocated cataract, two types of lOL were used as scleral-fixated posterior chamber lOL . First group was with four seal loops, the second group was with two open loops. All 21 patients (23 eyes) took the examination of the best corrected visual acuity, intraocular pressure, fundus, and lOL decentration using camera system attached to slit - lamp ophthalmoscope and lOL tilted using ultrasound biomicroscopy (UBM) at 6mo after surgery.RESULTS: After 6mo, all patients had improved eye sight. There was significant difference in the mean lOL decentration between the two groups ( 0. 57mm vs 0. 79mm, P<0. 05). There was significant difference in the mean lOL tilted degree between the two groups (6° vs 11°, P<0. 05) .
CONCLUSlON: lOL with four loops are more appropriate as scleral-fixated posterior chamber lOL with less tiltness and dicentration.

?AlM: To observe the situations of different surgical methods on dry eyes in patients with pterygium excision combined transplantation.
?METHODS: Seventy-eight cases ofpterygium patients (81 eyes ) were randomly divided into three groups. Group A underwent pterygium excision combined large autologous conjunctival flap transplantation; group B underwent pterygium excision combined with small conjunctival flap;group C underwent pterygium excision combined with small conjunctival flap with autologous limbal stem cell. Repair of postoperative corneal epithelium, 1, 3mo preoperation and postoperation tear film break up time ( BUT ) and questionnaire of ocular surface disease index ( OSDl ) were observed among three groups, which caused the situation of dry eyes by pterygium and pterygium excision were evaluated.
?RESULTS: BUT: Group A was shorter than that in groups B and C at 15d postoperation (P<0. 05); at 1mo postoperation, group A was no statistical difference with groups B and C (P>0. 05). Postoperative dry eye ratio of group A was higher than that in groups B and C at 1mo postoperation ( P < 0. 05 ). There was no statistical difference between group B and group C ( P>0. 05 ) , but group C showed lower postoperative dry eye ratio. Corneal epithelium recover time of group A was longer than that in groups B and C (P<0. 05). There was no statistical difference between group B and group C ( P>0. 05), but group C showed a tendency to be shorter recover time.
? CONCLUSlON: Pterygium excision combined with small conjunctival flap and autologous limbal stem cell shows guickly corneal epithelium recover and low dry eye ratio and deserve to recommended.

Objective The aim of the study is to approach the clinical significance of the change of ST segments after di- rect percutaneous transcoronary angioplasty(PTCA) combined with Lipo-PGE_1 in treating Acute Myocardial Infarction (AMI).Methods The change of the ST segments on EKG of 76 patients with AMI are observed in 30 minutes after un- derwent direct PICA combined with Lipo-PGE_1,and the relations are analyzed that are prospectively to their therapy effect,the degree of injured cardiac muscle,the cardial functions,and the prognosis.Results The patients who treated with the PCTA combined with Lipo-PGE_1 ST segments on EKG 30 minutes after operations reduced significantly,cardiac muscle is injured lowly,their cardial functions are better.Conclusion The change of ST segments after direct percutane- ous transcoronary angioplasty (PTCA) combined with Lipo-PGE_1 in treating acute myocardial infarction is one of the guide line to estimate the perfnsion of cardiac muscle,and to estimate prognosis farther.

Based on the analysis of current condition of local medical schools and medi-cal talents demand at the grassroots level,this paper indicates that,taking students’personality development as a breakthrough point,with practice platform construction as main part,supple-mented by multi-knowledge hierarchy and scientific and cultural exposure,backed by workable policy.

Objective To evaluate the additional efficiency of aldosterone blockers (AB) during angiotensin Ⅱ receptor blockers (ARB) treatment on hypertensive left ventricle hypertrophy in the elderly. Methods Forty-five cases of hypertensive left ventricular hypertrophy detected by Doppler ultrasonic cardiogram examination were enrolled,and were randomized to receive treatment with ARB plus AB (Group A) or ARB plus diuretics (Group B) for 48 weeks. The indicators of left ventricle hypertrophy were checked before and after the treatment. Results The both regimens could significantly decrease the blood pressure,and there was significant difference in the effects on lowering blood pressure between the regimens. Both regimens could alleviate left ventricle hypertrophy,but the regimen of ARB plus AB was superior to the regimen in Group B. Conclusion The addition of AB treatment during the ARB treatment was a good antihypertensive regimen for reducing left ventricle hypertrophy.

Objectives To investigate the activities of daily living and analysis of the influencing factors among elder hospitalization patients.Methods A series of scales including Activity of Daily Living Scale,Mini-Nutritional Assessment,Mini Mental State Examination,Geriatric Depression Scale 15,Falls Risk Assessment Tool and Euro Qol-5D Questionnaire were used to assess the physical and psychological health status among elder patients at first hospitalization,as well as their social-economic status,and to analyze the activities of daily living and influencing factors.Results Interviewees with less than nine years educational level had 5.93 (95 ％ CI:1.14-33.23)times higher risk for impaired activities of daily living than those with higher education levels.Patients with EQ-5D score ≥1 scale or with cognitive disorder showed 2.86 (95％ CI:1.04-8.05) times or 18.14 (95 ％ CI:1.64-540.63) times higher risks for impaired activities of daily living than their normal controls,respectively.The risks for the decreasing activities of daily living were increased along with ageing (P =0.025).There was a marginal correlation between regular exercise and activities of daily living(P=0.104).Conclusions Educational level,health status and cognitive function are important factors for activities of daily living among elder hospitalization cases and enlarged sample size is required for validation.
