Objective To construct baculovirus expression system for the human plasminogen kringle 5(hK5) gene,and detect its expression in Spodoptera frugiperda 21(sf21). Methods Baculovirus Bacmid-rhK5 was prepared with bac-to-bac baculovirus expression system,and sf21 cells were infected.The expression of rhK5 in sf21 cells was determined by Western blot.The activity of purified protein was detected by vascular endothelial cell inhibition test. Results The pFastBac HTB-rhK5 was successfully constructed,and sf21 cells were transfected with the constructed vector.The output of rhK5 obtained was 90 ug/L,and the protein possessed the inhibitory activity of endothelial cell proliferation.The median effective dose(ED50) was 4 ug/mL. Conclusion The rhK5 baculovirus expression vector is highly expressed in sf21 cells,which lays a foundation for the the expression of rhK5 protein with biologic activities.

Objective:This study aimed to investigate the expressions of EZH2 and Ki-67 in the salivary adenoid cystic carcino-ma (SACC) of humans and their correlation. Methods:A total of 42 cases of SACC tumor tissues and 5 cases of normal tissues were considered to determine the expressions of EZH2 and Ki-67 by immunohistochemistry. The relationship and correlation of such expres-sions with the clinicopathological characteristics were also analyzed. Results:The expression of EZH2 was notably higher in SACC than in normal tissues (P<0.05). EZH2 expression was detected in 66.67%(28/42) of the tumor tissues. This expression was correlated with pathological grade and clinical stage. By contrast, EZH2 expression did not correlate with gender, age, and localization. EZH2 was not expressed in normal tissues. The incidence of EZH2 expression in the Ki-67 positive group was 75.76%(25/33) and the incidence in the Ki-67 negative group was 33.33%(3/9). The difference between the two groups was statistically significant (P<0.05). Conclu-sion:The increased expression of EZH2 in SACC was related to tumor proliferation. EZH2 may participate in tumor cell proliferation via cell cycle management.

Objective To investigate the mechanisms of mesenchymal stromal cells (MSCs) in promoting the transplanted islets neovascularization.Methods We performed co-transplantation of allogeneic islet and MSCs into non-obese diabetic (NOD) mice and the lymphocyte chimeric rate was detected by flow cytometry.The MSCs migration,transformation and secretion of cytokines were detected by immunofluorescence.Results In mice of co-combination transplantation of islet with MSCs,donor lymphocytic chimerism in graft was increased.BM-MSCs can migrate to transplanted islet,differentiate into vascular smooth muscle cells,and also secrete vascular endothelial growth factor (VEGF).Conclusions MSCs can migrate to transplanted islet and promote neovascularization.Also,it enhanced allograft immune tolerance of islet grafts via increasing donor lymphocytic chimerism.
6.Efficacy of adjunctive intravitreous injection with Lucentis for neovascular glaucoma
International Eye Science 2014;(6):1077-1079
AIM: To observe the clinical efficacy of adjunctive intravitreous injection with Lucentis for the treatment of neovascular glaucoma ( NVG) .
METHODS:The retrospective case series study included 25 eyes of 25 patients who underwentintravitreous injection with Lucentis. Patients firstly received an intravitreous injection with Lucentis (0. 5mg/0. 05mL), after the regression of neovascularization of the iris, patients accepted different surgical treatments according to different etiopathogenesis condition. Iris, chamber angle neovascularization condition, intraocular pressure, and visual acuity were observed postoperatively. The follow-up duration was 3mo.
RESULTS:After 3-7d of intravitreous Lucentis injecting, iris and chamber angle neovascularization was totally faded in 20 cases (20 eyes) and was not completely faded in 5 cases ( 5 eyes ) . Additional treatments were compound trabeculectomy ( 14 cases, 14 eyes ) , vitrectomy ( 4 cases, 4 eyes ) . The patients' mean intraocular pressure was 43. 42 ± 10. 99mmHg before treatment, which decreased rapidly when they came out of the hospital (14. 26±7. 64mmHg, P<0. 05) and stabilized during the follow-up 3mo (18. 76±5. 96mmHg, P<0. 05). Follow-up at 3mo, visual acuity improved or remained in 20 cases ( 20 eyes ) and decreased in 5 cases ( 5 eyes ) . The complete success, qualified success and failure were 21 eyes, 3 eyes and 1 eye, respectively.
CONCLUSION:Intravitreous injection with Lucentis can be used as an assisted treatment of NVG. According to different etiopathogenesis condition, it is an effective treatment to combine with other treatment methods for NVG.

Objective To evaluate contrast-enhanced ultrasound (CEUS) for the diagnosis and follow-up of hepatocellular carcinoma ( HCC) patients after percutaneous radiofrequence ablation ( RFA). Methods The data of 46 HCC cases were reviewed in our study. Results of contrast enhanced computed tomography (CT) , ultrasound contrast agent sonography and grey ultrasound were compared with each other pre- and after percutaneous radiofrequence ablation. Results Contrast agent ultrasound imaging had the same value with CT in preoperative diagnosis of HCC, with postive likelihood ratio of 1.26 and 1.31, respectively,sensitivity of 97% and 91% and specificity of 23% and 31% respectively. For grey ultrasound the positive likelihood ratio was 0.99, sensitivity and specificity was 76% and 23% respectively. The sensitivity and specificity of contrast-enhanced ultrasound after percutaneous radiofrequence ablation was 60% and 90% respectively, and the postive likelihood ratio and negative likelihood ratio was 6. 18 and 0. 44 respectively. The difference was significant while compared with CT (P = 0. 012). All cases were followed-up from 1 to 9 months, and all were alive with recurrence found by contrast-enhanced ultrasound in 3 cases. Conclusions Contrast agent ultrasound imaging is sensitive and effective in the diagnosis of HCC and follow-up after percutaneous radiofrequence ablation.

OBJECTIVE To study the in vitro activity of cefepime combined with sulbactam against carbapenem-resistant strains of Acinetobacter spp clinically isolated. METHODS The activity of each drug alone was determined against 24 isolates. Chequerborad synergy testing was then performed against all the isolates. RESULTS The percentage of the FIC index showed 33.3% synergism, 62.5% additive, 4.2% (1/24) indifference, and no antagonism tively. CONCLUSIONS Testing of cefepime and sulbactam combinations revealed synergism and additivity activity against some carbapenem-resistant strains(23/24) of Acinetobacter spp which could be likely to prove beneficial effect for the treatment of infections due to multidrug-resistant strains of Acinetobacter spp.
