AIM: To evaluate the effects of glycemic control on refraction in diabetic patients. METHODS: Twenty newly diagnosed diabetic patients were included in this study. The random blood glucose, HbA1c levels, fasting C-peptide and postprandial 2h C-peptide were measured before treatment. The patients with random blood glucose higher than 12.0mmol/L and HbA1c level higher than 10.0% were selected. Refraction, intraocular pressure, radius of the anterior corneal curvature, depth of the anterior chamber, lens thickness, vitreous length, and axial length were measured on admission and at the end of week 1, 2, 3 and 4 during glycemic control.RESULTS: A transient hyperopic change occurred in all the patients receiving glycemic control. The maximum hyperopic change was 1.60D (range 0.50±3.20D). Recovery of the previous refraction occurred between two and four weeks after insulin treatment. There was a positive correlation between the maximum hyperopic changes and the HbA1c levels on admission (r=0.84, P<0.05). There was a positive correlation between the maximum hyperopic changes and the daily rate of blood glucose reduction over the first 7 days of the treatment (r=0.53, P<0.05). During transient hyperopia, no significant changes were observed in the intraocular pressure, radius of the anterior corneal curvature, depth of the anterior chamber, lens thickness, vitreous length and axial length.CONCLUSION: Transient hyperopic changes occur after glycemic control in diabetic patients with severe hyperglycemia. The degrees of transient hyperopia are highly dependent on HbA1c levels before treatment and the rate of reduction of the blood glucose level.

Objective To evaluate effects of glycemic control on refraction in diabetic patients.Methods Twenty newly diagnosed diabetic patients were included in this study. The random blood glucose,glycosylated hemoglobin A1c( HbA1c) levels, fasting C-peptide and postprandial 2 h C-peptide levels were measured before treatment. The patients with random blood glucose ≥ 12. 0 mmol/L and HbA1c ≥ 10. 0%were selected. Refraction, intraocular pressure, radius of the anterior corneal curvature, depth of the anterior chamber, lens thickness, vitreous length, and axial length were measured on admission and at the end of week 1,2, 3 and 4 during glycaemic control. Results A transient hyperopic change occurred in all the patients receiving glycemic control with a mean maximum hyperopic changes of 1.6 D ( 0. 50 D ～ 3.20 D). There was a positive correlation between the magnitude of the maximum hyperopic changes and the HbA1 c levels on admission ( r = 0.84, P ＜ 0.05 ). There was a positive correlation between the magnitude of the maximum hyperopic changes and the daily rate of blood glucose reduction over the first 7 days of the treatment ( r = 0.53, P ＜ 0.05 ). There was no significant correlation between the magnitude of the maximum hyperopic changes and the levels of random blood glucose on admission. No significant correlation was observed between the maximum hyperopic changes and fasting C-peptide or postprandial 2 h C-peptide.There were no significant correlations between the magnitude of the maximum hyperopic changes and age,blood press, body mass index, triglyceride, total cholesterol, low-density lipoprotein or high-density lipoprotein. No significant changes were observed in the intraocular pressure, radius of the anterior corneal curvature, depth of the anterior chamber, lens thickness, vitreous length and axial length during glycemic control. Conclusions Transient hyperopic changes occur after glycemic control in diabetic patients with severe hyperglycaemia. The degrees of transient hyperopia are highly dependent on HbA1c levels before treatment and the rate of reduction of glucose level over the first 7 days of treatment. This is probably due to the decrease of refractive power by lens hydration, not morphological change of lens.

The effects of Guizhi Fuling capsule and its active ingredient combination within different concentration on SPL proliferate were observed by MTT method. The ratio of CD80/86, CD3CD25 and CD3CD69 was used to evaluate cell activation effects of Guizhi Fuling capsule and its active ingredient combination by FCM. Guizhi Fuling capsule with concentration of 400 mg · L(-1)can promote spleen lymphocyte proliferation, as well as the active ingredient combination, which showed the obvious dose-effect relationship. Compared with control group, the difference has statistical significance (P≤0.01). The result of FCM showed that Guizhi Fuling capsule and its active ingredient combination can promote CD80 and CD86 expression on spleen lymphocyte, and also can increase CD25 and CD69 ratio between spleen CD3+ cells. Compared with control group, the difference has statistical significance (P≤0.01). Thus, Guizhi Fuling capsule and its active ingredient combination may have immune-modulate effects, and the mechanism may have a close relationship with the lymphocyte activation.

Objective To analyze the clinical features of infantile cytomegalovirus(CMV) hepatitis with cholestasis and investigate intrahepatic cholestasis due to hepatocytic impairment caused by CMV infection.Methods Forty-seven children with CMV cholestatic he-patitis were divided into 2 groups according to the level of total bilirubin(TB):22 cases with serum TB lower than 136.8 ?mol/L(groupⅠ),and 25 cases with serum TB higher than 136.8 ?mol/L(groupⅡ).All children were treated with both gangciclovir and routine met-hods,and serum biochemistry were checked before and after treatment.SPSS 13.0 software was used to analyze the data.Results Forty-seven cases of infantile CMV cholestatic hepatitis had different degrees of jaundice,hepatosplenomegaly and abnormal liver functions.The differences of serum ALT and AST between the 2 groups had statistical significance,the levels of serum gamma glutamy transferase(GGT) and alkaline phosphatase(ALP) were lightly higher in groupⅡcompared with those in groupⅠ,but there were no statistical significance.TB,direct bilirubin(DB),ALT and AST were decreased in the 2 groups after treatment,GGT and ALP hadn′t decreased significantly after treatment.Conclusions CMV infection can injure hepatocytes and epithelials on each grade of bile duct,thus CMV hepatitis causes intrahepatic cholestasis.Cholestasis due to hepatocytic impairment deserves emphasis and intervention should be done as early as possible.Gangciclovir therapy for CMV infection manifest effective and safe in short-term.

Objective To discuss the imaging technology and characteristic of perfusion-weighted imaging in rabbit models of hepatic VX2 tumors. Methods Twenty-eight New Zealand rabbits were implanted in liver with VX2 tumor by tissue block. After routine scans were performed on 1.5 T MR scanner, 28 New Zealand white rabbits with VX2 carcinoma were divided randomly into treatment group and control group. Treatment group was divided randomly into group A, group B and group C, 7 animals per group. Perfusion weighted imaging(PWI) was performed in day 14, 25 and 35, respectively, after tumor implantation in all animals. Select the regions of interest (ROI) of the VX2 tumor center, tumor border and pars-tumor parenchyma. Maximal signal reduction slope ( SRSmax ) of the signal intensity versus time curves were created as quantitative variable, and the parameters were calculated and compared in all groups. Results Maximal signal reduction slope ( SRSmax ) of the signal intensity versus time curves were studied in 4 groups, 23 VX2 rabbits,7,5 and 6 in group A , B and C, respectively. The SRSmax of tumor center were ( 12. 6 ± 3.4), ( 9. 8 ± 2. 6 ) and ( 1.0 ± 0. 4 ), the difference was significant ( F = 10. 855, P < 0. 05 ). The SRSmax of tumor border were(48. 3 ± 2.4), (46. 2 ± 1.5 ) and (43. 6 ± 1.8 ) ( P > 0. 05 ). The SRSmax of para-tumor parenchyma were ( 14.4 ± 3.0 ), ( 12. 2 ± 1. 4 ) and ( 14. 8 ± 5.0 ) ( P > 0. 05 ). The difference was significant in different ROI in treatment groups( F value was 7. 435,8. 625 and 12. 595, respectively, P < 0. 05 ). Conclusion PWI can be used in evaluating the liver tumor angiogenesis and angio-degeneration with the treatment of HIFU. It will be possible for qualitative analysis of rabbit models of hepatic VX2 tumors by different treatments.

Objective To investigate the imaging characteristic of DWI in rabbit models of hepatic VX2 tumors after three-dimensional stereotactic conformal radiation therapy, and the characteristics of apoptosis after radiotherapy. Methods Sixty hepatic VX2 tumor models were successfully created. After the tumor grew to more than 1 cm in diameter, 40 tumor models were treated with SCRT and then divided into four groups using random number table. The remaining 20 tumor models were used as controls and randomly assigned to each group. MR scanning were performed at different time points ( 1 st day, 5 th day, 10 th day, 15 th day) for each group respectively. ROIs of the VX2 tumor tissues and normal liver tissue were taken and ADC values were measured to calculate their ratios. Cell apoptesis were determined by using TUNEL method. ADC values with their ratios and the apoptotic index were analyzed using one-way analysis of variance and SNK test was used for comparison among different time points of groups, while two sample t test was used for comparison between the groups. Results On the 1 st day, 5 th day, 10 th day, and the 15 th day, the ADC ratios of the radiotherapy groups were 0.74 ±0. 15(n =8), 1.04 ±0.09(n =7), 1.43 ±0. 12 (n = 7 ), 1.25 ± 0. 23 (n = 8 ) (F = 24. 221, P ＜ 0. 01 ), the corresponding ADC ratios of control groups were 0. 78 ±0.07(n =5), 0.79 ±0.07(n=4), 0.83 ±0. 14(n =4), 0.97 ±0. 19(n =4). The ratios of ADC values for radiotherapy groups and control group were compared, and the t value was 0. 569 ( P ＞0.05), 4.417(P＜0.05), 7.259(P ＜0.01), 1.957(P＞0.05) respectively for each time point. On the 1 st day, 5 th day, 10 th day, 15 th day, the apoptotic index of the radiotherapy groups were 0. 39 ±0. 13(n=8), 0.29 ±0.08(n=7), 0.28 ±0.07(n=7), 0.58 ±0. 19(n=8,F=8. 128,P＜0.05), while the corresponding apoptotic index of control groups were 0. 26 ±0. 13(n =5), 0. 18 ±0. 03(n =4), 0. 16 ±0. 06(n =4), 0. 18 ±0. 08(n =4,F= 1. 006,P ＞0. 05). The apoptotic index value for radiotherapy groups and control group were compared, with t value of 1. 716 ( P ＞ 0.05 ), 2. 348 ( P ＜ 0. 05 ), 2. 386 ( P ＜0. 05 ), 3. 756( P ＜0.01 ) respectively. Conclusion DWI ADC values can reflect the dynamic changes of cell apoptosis in hepatic VX2 tumors after radiotherapy at different time points.
