AIM: To compare the effectiveness on 10g/L cyclopentolate and 10g/L atropine on cycloplegia in children before optometry.
METHODS:Eighty eyes of 40 children among 4-12 years old with refractive error were recruited in this study. 10g/L cyclopentolate eye drops were topically administered once per 5min for 3 times and optometry was performed after 45min. Three days after that, 10g/L atropine sulfate eye gel then was used 3 times per day for consecutive 3d and again the refractive diopter was obtained at the 4th d. The differences of the results in retinoscopy refraction were compared between 10g/L cyclopentolate eye drops and 10g/L atropine sulfate eye gel.
RESULTS: Therefraction results of those given 10g/L cyclopentolate eye drops and 10g/L atropine sulfate eye gel were no statistical different in both 4-8 years group and 9-12 years group with myopia (≤-3. 00D) (P=0. 411, 0. 924). The differences of refraction results of both the drugs were significant in 4 - 8 years group with low hypermetropia, medium hypermetropia and high hypermetropia (P=0. 007, 0. 007, 0. 009). No significant difference was found in 9 - 12 years group with low hypermetropia (P= 0. 592), given 10g/L cyclopentolate eye drops and 10g/L atropine sulfate eye gel, but the differences of refraction results of both the ophthalmic preparations above were significant in 9-12 years group with medium and high hypermetropia (P=0. 039, 0. 012).
CONCLUSION:Both 10g/L cyclopentolate eye drops and 10g/L atropine sulfate eye gel have the cycloplegic effects, but their cycloplegic effects are significant different among hypermetropia children. Thus, the reasonable cycloplegic should be chosen according to the specific situation.

Objective To explore the dynamic change of serum leptin interleukin-6(IL-6),and interleukin-8(IL-8)during cerebral infarction,and to analyze the possible relationship between these factors and the severity of the disease.Method The levels of serum leptin,IL-6 and IL-8 were measured by radioimmunoassay in 60 patients with acute cerebral infarction,who were admitted to the hospital within 24 hours after stroke.Patients' neurologic impairment were evaluated by European Stroke Scale(ESS)at 1,3 and 7 days respectively after hospitalization.At the same time,another 30 normal adults were enrolled set as control group. Results The levels of serum Leptin,IL-8 in patients group after at 1 days,3 and 7 days were higher than those in the controls(P0.05).The ESS of these patients were 76.77?26.42,70.02?29.17,74.65?28.42 respectively,after 1,3 and 7 days.It shown that ESS simply correlated to the level of IL-8(P0.05).Statistic analysis was carried,but by using t test and linear correlation.(SPSS11.5 statistical package).Conclusion Leptin,IL-6 and IL-8 probably play a role in the inflammatory,reaction during acute cerebral infarction.The IL-8 may reflect the severity of the disease.

Background Researches demonstrated that ciliary neurotrophic factor (CNTF) can enhance survival and promote differentiation of neutron.Meanwhile,CNTF also is thought to play an important role in the development of visual pathway.But,less studies are reported in the relationship of CNTF and form deprivation amblyopia.Objective This study was to investigate the expressions of CNTF in visual cortex area 17 in form deprivation amblyopia model.Methods Twelve 4-week-old cats were randomized into normal group and form deprivation amblyopia group.Monocular form deprivation amblyopic models were established in 6 cats by eyelids suture method.Pattern visual evoked potential(P-VEP) was recorded to evaluate the amblyopic models 16 weeks later following the eyelids suturing.Then,bilateral visual cortex tissue was incised at a vertical in sagittal axis fashion to prepare the section.Nissl staining was used to detect the morphologies of neurons.Expression of CNTF in Ⅰ-Ⅵ layers of visual cortex area 17 was located and quantified by immunochemistry.The positive cell number and gray scale for CNTF were calculated and compared between two groups.The use of the animals complied with Regulations for the Administration of Affairs Coucerning Experimental Animals by State Science and Technology Commission.Results Compared with the normal group,P-VEP amplitude was significantly reduced (6.11 ±1.56 μV vs.11.42±t.92 μV) and latency was significantly prolonged(75.77±9.83 ms vs.58.56±7.17 ms) in the form deprivation amblyopia group (t=5.272,3.464,P＜0.05).Nissl staining showed that the number of neurons in the form deprivation amblyopia group was less than that in the normal group.In the form deprivation amblyopia group,neurons became shrinkage and turned round,cytoplasmic processes get shortened,and the nucleus became small.The number of Nissl bodies was decreased.lmmunochemistry showed the positive neutrons for CNTF in Ⅰ-Ⅵ layers of visual cortex area 17 in hoth normal cats and model cats with the more positive cells in Ⅱ-Ⅳ layers.Compared with the normal group,the positive cell number for CNTF was significantly reduced in Ⅱ-Ⅳ layers of visual cortex area 17 in the form deprivation amblyopia group (Ⅱ layer:95.93±8.24 vs.116.25±6.52;I layer:102.65±7.45 vs.125.23±8.21;Ⅳ layer:l10.65±6.85 vs.139.54±4.26) (t=4.737,4.989,8.773,P＜0.05).In addition,the gray scale of CNTF positive cells was significantly lower in Ⅱ-Ⅳ layers of visual cortex area 17 in the form deprivation amblyopia group than that the normal group (Ⅱ layer:106.98 ± 8.86 vs.138.65 ± 6.38 ; Ⅲ layer:109.56 ± 8.69 vs.149.59 ±8.55;Ⅳ layer:l16.65 ±9.52 vs.155.76±9.87) (t=7.105,8.043,6.986,P＜0.05).Both CNTF positive cell number and gray scale in Ⅰ,Ⅴ,Ⅵ layers of visual cortex area 17 had no significant differences between two groups (P＞0.05).Conclusions Form deprivation in critical period of a new born animal may lead to distributing abnormality of CNTF in visual cortex,which maybe play a role in the development of form deprived amblyopia.

ObjectiveTo discuss the characters and management of renal lymphangiectasia.MethodsThe clinical data of two cases of renal lymphangiectasia were reviewed. The first patient was a 37-year-old woman with the chief complaint of lumbago in the right flank for 8 days.B-ultrasound showed mixed echo in perinephric space. On CT, similar appearances of fluid collections were seen, but not conspicuous. Conservative treatment was taken for three weeks and the symptoms were relieved. Three month later the patient had right lumbago relapse. CT scan revealed a large amount of fluid collection under the capsule of the right kidney. Percutaneous drainage was carried out. Two months later B-ultrasound showed fluid collection in perinephric space and percutaneous drainage again the fluid was sent to pathology. The second case was a 32-year-old woman with the chief complaint of lumbago in the left flank for the past three years. Ultrasonography revealed hyperechoic surrounding the left kidney. CT scan showed a left perinephric collection of fluid attenuation and circumferentially draping around the kidney. Renal lymphangioma was diagnosed and the patient underwent surgery.ResultsNeedle aspiration of the perinephric fluid was carried out, and laboratory analysis showed most leucocytes were lymphocytes. The pathologic diagnosis of the first case was renal lymphangiectasia. There was no recurrence during follow - up of two months. The second case was diagnosed renal lymphangioma pathologically. Follow - up for nine years, revealed no relapse.ConclusionsUltrasonography and CT contributed to the diagnosis of renal lymphangiectasia. Needle aspiration bioposy and histology could confirm it. Treatment of asymptomatic cases is not required. When collections are very large and cause symptoms, percutaneous drainage may be carried out however there is a risk of relapse.

OBJECTIVETo explore the effect of Yixintai Granule (YG) on mRNA and protein expression levels of AQP2 in renal medulla of chronic heart failure (CHF) rabbits.

METHODSCHF rat model was established by ear marginal vein injection of adriamycin. Successfully modeled rabbits were divided into the model group, the high (8.4 g/kg), middle (4.2 g/kg), and low dose (2.1 g/kg) YG group, and the Furosemide group (2 mg/kg). Besides, a normal control group was set up. Equal volume of physiological saline was administered to rabbits of the model group and the normal control group by gastrogavage. YG at different doses was administered to rabbits of the 3 YG groups by gastrogavage. The intervention lasted for 4 weeks, once per day. After treatment the urine volume and pathomorphological changes of renal medulla tissue were observed. mRNA and its protein expression levels of AQP2 were detected.

RESULTSCompared with the normal control group, the urine volume decreased significantly, mRNA and protein expression levels of renal medulla AQP2 increased significantly in the model group (all P < 0.01). Compared with the model group, the urine volume increased significantly, and mRNA and protein expression levels of renal medulla AQP2 decreased significantly in all medicated groups (all P < 0.01). Compared with the low dose YG group, the urine volume significantly increased and the mRNA expression level of renal medulla AQP2 significantly decreased in the middle and high dose YG groups (all P < 0.01). The expression level of AQP2 protein significantly decreased in the high dose YG group (P < 0.01). Pathological changes of the renal medulla was the most obviously seen in the model group. But they were alleviated to various degrees in all medicated groups. They were more obviously attenuated in the middle and high dose YG groups.

CONCLUSIONYG could improve CHF possibly through down-regulating mRNA and protein expression levels of AQP2 in renal medulla, and elevating the urine volume.
