AlM: To explore clinical efficacy of hyperosmotic glucose after cataract surgery.METHODS: Eighty eyes ( 80 cases ) with ll level and above grades corneal edema after small incision cataract operation were enrolled. They were randomly divided into treatment group and control group. Control group used TobraDex eye drops and other conventional treatment and the treatment group received hyperosmotic glucose(500g/L) with the bases of the control group. The regression of corneal edema was observed by slit lamp microscope. SPSS 17. 0 statistical software was used for statistical analysis.RESULTS: The level of corneal edema at the first day after surgery, age, sexuality and nuclear hardness in the treated group were compared with those in the control group, the differences were without significances ( P>0. 05). Disappearance time of corneal edema was 4. 95 ± 3. 62d of the treatment group, and was 6. 80±3. 33d of the control group, the treatment group was better than control group (t=8. 55, P=0. 00).CONCLUSlON: Hyperosmotic glucose has exact and obvious efficacy for early corneal edema after cataract surgery.

OBJECTIVE:To explore the effects of pharmaceutical care on blood glucose control and medication compliance in patients with diabetes mellitus. METHODS:Nighty-two discharged patients with diabetes mellitus in our hospital from Apr. to Sept. 2015 were divided into intervention group and control group by random number table method,with 46 cases in each group. Both groups were given Chlorpropamide tablets+Metformin glibenclamide tablets(Ⅰ)for 3 months;intervention group additionally re-ceived pharmaceutical care as medication education,telephone follow-up,etc. The levels of glycosylated hemoglobin and blood glu-cose,medication compliance were compared between 2 groups before and after treatment. RESULTS:Before treatment,there was no statistical significance in the levels of glycosylated hemoglobin and blood glucose,or medication compliance between 2 groups (P>0.05). After treatment,the levels of glycosylated hemoglobin and blood glucose in 2 groups were significantly decreased,and the intervention group was significantly lower than control group;the effects of blood glucose control in patients younger than 60 years old were better than in patients older than 60 years old,with statistical significance(P<0.05). After one month of treatment, the proportion of good medication compliance were increased significantly in 2 groups,and the intervention group was significantly higher than control group. After 3 months of treatment,the proportion of good medication compliance in 2 groups were significant-ly higher than before treatment,and 1 month after treatment,while the intervention group was significantly higher than control group. The improvement of medication compliance in patients younger than 60 years old was better than in patients older than 60 years old,with statistical significance (P<0.05). CONCLUSIONS:Pharmaceutical care contributes to blood glucose control and improves the medication compliance,especially for those younger than 60 years old.

Fracture healing has long been a major concern for orthopedists.Currently,about 10% of fracture patients still have poor fracture healing or bone nonunion.In recent years,research has found that nerve growth factor(NGF)can promote fracture healing.This article reviews the mechanism and research progress of NGF in promoting fracture healing.NGF can promote vascular regeneration and nerve growth at callus and plays an important role in the proliferation and migration of bone cells.New animal experiments and clinical trials have confirmed the role of NGF in promoting fracture healing and further revealed its possible mechanism of action.Further research on NGF can provide new ideas for promoting fracture healing,especially for treating nonunion.

Objective To assess the image quality (IQ) of an iterative reconstruction (IR) technique (iDose4) from prospective electrocardiography (ECG)-triggered coronary CTA on a 256 MSCT scanner and determine the optimal dose reduction using IR that can provide IQ comparable to filtered back projection (FBP).Methods Prospectively ECG gated CCTA were performed on 120 patients [76 men,44 women; age:(53 ± 10)y] using a 256-slice MSCT (Brilliance iCT,Philips Healthcare).The control group (Group A,n =30) were scanned using the conventional tube output (120 kVp,210 mAs) and reconstructed using FBP.The other 3 groups were scanned with the same kVp but successively reduced tube output as follows:B (n =30):105 mAs,C (n =30):84 mAs:D (n =30):65 mAs and reconstructed using IR levels of L4 to L6,respectively.All images were reconstructed using the same kernel (XCB).Two radiologists graded IQ in a blinded fashion on a 4-point scale (4-excellent,3-good,2-fair and 1-poor).Quantitative measurements of CT values,image noise,Signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were obtained in each group.Analysis of variance (ANOVA) was used for comparisons of objective evaluation indices (noise,CNR) and radiation dose (CTDIvol,DLP,ED) between the four groups.The Kruskal-Wallis test was used for comparisons of demographic data and for detection of differences in subjective evaluation of IQ among groups.A level of P ＜ 0.05 was considered statistically significant.A ROC analysis was performed to determine a radiation reduction threshold up to which excellent IQ was maintained.Results There was no significant differences in objective noise among Groups A (37.4 ±7.9) HU,B(33.2±7.1) HU,C(35.7±9.8) HU,and D(36.0±6.8) HU (F=1.48,P=0.22).There was no significant differences in CNR among Groups A(15.0 ±2.3),B(16.5 ±3.6),C(16.3 ±3.5),and D(15.3±2.8) (F=1.70,P =0.17).Group B and C had good and excellent scores of the subjective IQ (≥3),and there was no significant differences in the scores of the subjective IQ between Group A,and Groups B,C (P =0.30-1.00).Significant differences in image sharpness and study acceptability were observed between groups A and D (P ＜ 0.01).Using the criterion of excellent IQ (score 4),the ROC curve of dose levels and IQ acceptability established a reduction of 60％ of tube output (Group C) as optimum cutoff point (AUC:0.76,95％ CI:0.65-0.87).The effective dose (ED) of Group C was 61％ lower than that of Group A,(1.2 ± 0.1) mSv vs.(3.1 ± 0.6) mSv.Conclusion Iterative reconstruction techniques can provide 61％ ED reduction in prospectively-triggered coronary CTA using 256-slice MSCT while maintaining excellent image quality.

PPP2R5C is one of the members of regulatory subunits of protein phosphatase 2A (PP2A), which plays a critical role in cell proliferation, differentiation and transformation, based on its induction of dephosphorylation of P53 at various residues. Recently, it was characterized that the alteration of expression pattern of PPP2R5C is associated with cell malignant transformation, thus PPP2R5C was thought as a marker for progressive disease in B-CLL. In this article the gene structure and biological function of PPP2R5C as well as relation of PPP2R5C with genesis and development of cancer were discussed.
