AIM: To investigate the effect of low intensity white light irradiation on the retinas of mice.
METHODS: Thirty C57BL/6J mice were randomly divided into two groups. The number of the mice in each group was 15. The mice in experimental group received dark adaptation from 5:00p. m. to 6:00p. m. , and then exposed to LED white light from 6:00p. m. to 7:00p. m. everyday for a month. At 1, 3, 7, 14 and 30d after the beginning, we examed the histology of mice retinas, calculated the thickness of outer nuclear layer ( ONL ) , inner nuclear layer ( INL ) and analyzed electrophysiology of mice.
RESULTS:One month after experiment, compared to the control group, the latency of Rod-R a wave of the mice in experimental group significantly prolonged, the amplitude of Cone-R b wave of the mice in experimental group significantly decreased and the latency of b wave of the mice in experimental group significantly prolonged ( P<0. 05). There are no significant difference in the histology of retina, ONL and INL thicknesses.
CONCLUSION: 100lux low intensity white light could give rise to the impairment of the retinal functions in dark-adapted mice.

Objective To study the effect of glucocorticoid on serum interleukin(IL)-1,IL-6,transforming growth factor-?_1(TGF-?_1) and tumor necrosis factor alpha(TNF-?) in children with primary nephrotic syndrome(PNS).Methods The levels of cytokines on serum were compared in 3 different patho-type,and IL-1,IL-6,TGF-?_1 and TNF-? in serum were detected using enzyme-linked immunosorbent assay(ELISA) in 25 children with PNS before and after treatment with glucocorticoids.Results Significant difference of IL-1,IL-6,TGF-?_1 and TNF-? were found between the two group before and after the treatment(P0.05).The level of TGF-?_1 in MCD was lo-wer than that in MsPNG,FSGS before and after the treatment(P0.05),and the level of it in FSGS was higher than that in MsPNG after the treatment(P

Acidolysis kinetics on the process of the hydrolysis acidification by using glucose as the only energy sources was researched.It was concluded that the acidolysis kinetics constants are V_(max)=8.45d~(-1) and K_s=1089mg/L,under the circumstances of a temperature 37℃?0.5℃and the influent pH value 6.5.The results show that the rate of anaerobic acidification process is greater than that of completed an- aerobic or anoxic process.

OBJECTIVETo compare the changes of digestive and absorptive functions in three different models of Pi-deficiency syndrome (PDS).
METHODSExperimental mice were divided into four groups, the control group(CG), the rhubarb group (RG), the exhaustion group (EG) and the over-exertion group(OG). Criteria including general physical signs, D-xylose excretion rate, serum amylase activity, velocity of stomach emptying and enterokinesia, serum gastrin content and indexes of organs were determined before and after treatment.
RESULTSDecrease of D-xylose excretion rate and increase of stomach emptying and enterokinesia velocity appeared in all the three PDS models. As compared with CG, changes of all indices in OG were significant, while the decreasing of spleen index and serum amylase activity in EG, and the changes of serum gastrin content and thymus index in RG were insignificantly different.
CONCLUSIONAll the changes in various criteria showed that PDS mice model established by over-exertion was superior to that established by frequently used methods as purging with rhubarb and exhausting by swimming.

Objective To evaluate the methods and consequences of surgical technique in the treatment of Stanford A aortic dissection.Methods 108 patients with type Standford A aortic dissection underwent surgery in our study,including urgent surgery in 53 and selective surgery in 55.The operation was performed under deep hypothennic circulatory arrest (DHCA) in 85 cases.Surgical procedures included ascending and semi arch replacement or total arch replacement (some cases combined with stented graft implanted into the descending aorta),"elephant trunk" procedure.Concomitant procedures included repair of intimal tear in arch or descending aorta,Bentall procedure,aortic valve replacement,Cabrol or modified Cabrol procedure,aortic valvuloplasty,mitral valvuloplasty or mitral valve replacement,tricuspid valvuloplasty and CABG.Results In-hospital mortality was 6.5% (7 of 108 patients).The mor- tality was 7.5% (4 of 53 patients) in urgent surgery group and in elective surgery group was 5.4% (3 of 55 patients).Ninety six percent survived patients were followed up for 1 month to 13.3 years [mean (3.2?1.3) years] and 2 deaths occurred during the fel- low-up period.3 patients underwent re-operatian.Conclusion The choice of surgical procedures depend on the location of intimal tear for Stanford A aortic dissection.The better operative effects can be expected with proper surgical indication,perfecting surgical technique,and enhancing postoperative treatment.

Objective To observe changes of luteinizing hormone (LH), follicle-stimulating hormone (FSH) and testosterone (T) in umbilical vein blood between male and female neonates, and assess the effect of serum LH, FSH and T on fetal growth.Methods Umbilical vein blood was obtained from 130 neonates (64 females and 66 males) in the second hospital of changshu city. According to birth weight, 130 neonates were divided into 3 groups: macrosomia (n=28), intrauterine growth restriction (IUGR) (n=31) and normal neonates (n=71). The serum levels of LH, FSH and T were measured by radioimmunoassay.Results 1.The levels of LH, FSH and T in umbilical vein blood were significantly higher in male neonates than those in females (P

Objective:To investigate the effectiveness of irbesartan in combination with ramipril for treatment of chronic heart failure in patients with rheumatic heart disease(RHD).Methods:A total of 120 RHD patients with chronic heart failure were randomized into treatment group(n=60)and control group(n=60)after valve replacement.All patients received regular ramipril treatment(5 mg/d);treatment group were also given irbesartan(150 mg/d).The patients were followed up for 6 months.The indices of observation included cardiac function(NYHA Class),6-Minute Hall Walk distance,and echocardiographie parameters.Results:Six months later the cardiac function in the treatment group was obviously improved compared with the control group;the patients in the treatment group had significant increase in 6-Minute Hall-Walk distance and improvement in echocardiographic parameters(left ventricle end-systolic diameters,end-diastolic diameter,ejection fraction, fractional shortening,P
