AIM: To observe the comparison of vitrectomy combined drug therapy ( Ranibizumab injection ) and single vitrectomy for proliferatived diabetic retinopathy ( PDR ) and the influence of the curative effect and prognosis of patients.
METHODS:In this study, 112 cases (125 eyes) with PDR were selected and randomly divided into experimental group and control group ( n= 56 ) . Fifty-six cases ( 61 eyes ) in experimental group were injected by drug therapy of 0. 5mg ranibizumab and received vitrectomy;In control group, 56 cases ( 64 eyes ) were received single vitrectomy. The intraoperative and postoperative differences of clinical indicators were analyzed in two groups.
RESULTS: The average operation time, intraoperative electric coagulation hemostasis rate and iatrogenic hiatal incidence of the experimental group were lower than that of the control group:(95. 00±13. 00) min vs (133. 00±14.5) min, 11% vs 34%, 5% vs 20%, respectively (P<0. 05). The anterior chamber and vitreous body cavity hemorrhage rate within postoperative 1mo in the experimental group were lower than that of the control group:7% vs 23%, 5% vs 12%, respectively (P<0. 05). The postoperative visual acuity of experimental group was better than that of the control group:0. 375±0. 210 vs 0. 261±0. 170, respectively (P<0. 05).
CONCLUSION: Patients with PDR injected with ranibizumab in vitreous cavity before vitrectomy can effectively reduce the operation time, less intraoperative blood loss, the incidence of iatrogenic hiatus, and intraoperative and postoperative complications. The postoperative visual acuity was better than before.

In this study, the human umbilical vein endothelial cell model was used to study the regulating effect of lipophilic components in Salvia miltiorrhiza on angiogenesis, and explore its possible mechanism. The cell model was established to determine the effect of lipophilic components in S. miltiorrhiza on the proliferative activity and migration capacity of endothelial cells. Then the realtime fluorescence quantification PCR technology was applied to detect the changes in the gene expressions of angiogenesis-related cytokines VEGF-A, VEGF-C and MMP-9. The results showed that 5 mg x L(-1) lipophilic components in S. miltiorrhiza could inhibit the proliferation and migration of endothelial cells, and reduce the expression of VEGF-A and MMP-9 genes. It indicated that lipophilic components in S. miltiorrhiza may inhibit the proliferation and migration of endothelial cells by inhibiting the expression of VEGF-A and MMP-9 genes, so as to show the inhibitory effect on angiogenesis.

Applications of network pharmacology are increasingly widespread and methods abound in the field of drug development and pharmacological research. In this study, we choose rosiglitazone compound as the object to predict the targets and to discuss the mechanism based on three kinds of prediction methods of network pharmacology. Comparison of the prediction result has identified that the three kinds of prediction methods had their own characteristics: targets and pathways predicted were not in accordance with each other. However, the calcium signaling pathway could be predicted in the three kinds of methods, which associated with diabetes and cognitive impairment caused by diabetes by bioinformatics analysis. The above conclusion indicates that the calcium signaling pathway is important in signal pathway regulation of rosiglitazone compound, which provides a clue to further explain the mechanism of the compound and also provides a reference for the selection and application of methods of network pharmacology in the actual research.

Objective To explore the expression of Survivin in colorectal cancer tissue and its relationship with clinicopathological features.Methods In situ hybridization was used to examine the expression of Survivin mRNA,and immunohistochemical method was used to detect the expression of Survivin protein in 60 cases of colorectal cancer and 30 cases of colorectal normal mucos tissue.The relationship of the expression of Survivin protein with clinicopathological features of colorectal cancer was analyzed.Results The positive expression rate of Survivin protein in colorectal normal mucos tissue (10.00％,3/30) was lower than that in colorectal cancer tissue (73.33％,44/60),and there was significant difference (P ＜ 0.05).The positive expression rate of Survivin mRNA in colorectal normal mucos tissue (6.67％,2/30) was lower than that in colorectal cancer tissue (63.33％,38/60),and there was significant difference (P ＜ 0.05).The expression of Survivin mRNA was positively correlated with depth of invasion,lymph node metastasis,liver metastasis,peritoneal micrometastasis and TNM stage in patients with colorectal cancer (P ＜ 0.01),but had no correlation with gender,age,tumor size,location,degree of differentiation and histological type (P ＞ 0.05).Conclusions The specific high expression of Survivin protein has a high correlation with the occurrence,development,infiltration of colorectal cancer.Survivin may be used as a marker for prognosis of patients with colorectal cancer.

Objective To study the genotype frequencies of peroxisome proliferator-activated- receptors- gamma (PPAR?) C161→T gene and its possible association with serum lipid levels and dietary intakes. Methods PCR-PFLP method was used to detect the polymorphism of PPAR?C161→T gene of 800 adults in Shanghai. Their physical examinations,dietary survey and the levels of serum lipid profile , including TG、TC ,HDL and LDL were analyzed. Results (1) The genotype frequencies of PPAR?C161→T CC,CT and TT were 35.1 %, 47.0 % and 17.9 % respectively , which were in agreement with Hardy- Weinberg equilibrium. There was no significant difference in distribution of genotypes or allele between the hyperlipidemia group and the control group and the result was same between male and female subjects. (2)After adjusting age,gender and body mass index, the levels of TG were significantly different among three genotypes groups,the highest in CC genotype. (3) After adjusting age and gender, the intakes of protein were significantly different among three genotype groups. (4) There was significant difference in the negative correlation between energy,protein and carbohydrate and serum TG levels in hyperlipidemia group.Conclusion PPAR? C161→T gene polymorphism influenced serum TG level, while associated with protein intakes. It might contribute to the heterogeneity in TG response to dietiary intervention.

Objective To compare four methods of monitoring vascularization of tissue engineered bone in the rhesus so as to find our the best. Methods Twenty-five lower limbs of 13 rhesuses were used in this study to make models of tibial diaphyseal defect of 20mm which were to be fixed with an AO reconstruction plate of 7 holes. The monkeys were randomly divided into five groups according to defect filling materials: group A:?-tricalcium phosphate (?-TCP) and bone marrow stromal cells (BMSCs) and blood vessel bundles; group B:?-TCP and blood vessel bundles; group C:?-TCP and BMSCs; group D:?-TCP; group E: blank. Perfusion weighted MR imaging (PWMR), X-ray, radionuclide imaging and histological examinations were carried out at weeks 4, 8, 12 postop- eratively. The maximum slope rates of the single intensity-time curve (SS_(max)) and values of baseline (Sl_(?))were calculated at the same time points. Transmittances of the X-ray films were assessed. Ratios between isotope counts in region of interest (ROI) were calculated. Chinese ink perfusion and calculation of blood vessel areas were done for histological examinations, Results Compared with other groups, the SS_(max) in group A was the highest at weeks 4, 8, 12 postoperatively. In group A, the SS_(max) at week eight was significantly higher than that at week four (P= 0. 003), and the SS_(max) and transmittance of X-ray were negatively related at week 12 after operation (rs=-0. 892, P=0. 042), but the SS_(max) and blood vessel area were positively related (rs=0. 894, P=0.041)Conclusions PWMR can be a sensitive, quantitative, noninvasive and non-radiant method to monitor vascularization of tissue engineered bone, because SS_(max) of the single intensity-time curve of PWMR can reflect the most accurately the process of vascularization of tissue engineered bone.

Objective To investigate and analyze the clinical and imageological features of skull base erosion in nasopharyngeal carcinoma( NPC). Methods 67 NPC patients proved by pathology were retrospectively reviewed. All patients underwent both CT and MRI plain plus enhancement scan. Scan slices were performed from oral pharynx (lower border of second cervical vertebra) to suprasellar cistern by axial CT scans and axial, sagittal and coronal MRI scans. Results (1) 52 patients with skull base erosion were found with MRI, and only 35 patients with CT. The following structures and figures were difined with CT and MRI respectively: pterygoid plates 8,14; clivus 22,25 ; petrous apex 25 ,28 ; sphenoid body or sinus 19,25; sphenoid wing 9, 12; cavernous sinus 14,17. The display difference between CT and MRI had statistical significance ( x2= 9. 47 , P = 0. 02). (2) CT- defined skull base erosion was most bone destruction , however, not only bone destruction but also tumor crossing skull base structure could be defined by MRI. (3) The incidence of headache was 82.7% (43/52) , cranial nerve palsy was 67. 3% (35/52) , both headache and cranial nerve palsy was 57. 7% (30/52). Conclusion Headache and cranial nerve palsy are primary characteristics of the skull base erosion in NPC. MRI is superior to CT in defining both bone erosion and brain tissue abnormality.
