Objective To summarize the clinical experience of endovascular intervention for intra-cranial aneurysms, especially in the respect of the technique and management of intra-operative complications. Method The clinical data of 60 patients with intra-cranial aneurysms treated with endovascular intervention in the past 3 years were analyzed. The relevant literature especially with regard to the practical technique described was reviewed so as to potentiall minimize and properly manage the intra-operative complications. Results A total of 69 sacciform aneurysms and one dissecting aneurysm located at left vertebral artery (VA) were detected by using digital subtraction angiography (DSA) in 60 patients. There were 65 saccular aneurysms obliterated with constructive approach, and five of them treated with stent-assisted technique and four of them treated with ballon-assisted technique. The VA dissecting aneurysm was obliterated with coils by deconstructive approach with complete occlusion of its parent vessel. There were a total of 53 complete occlusions of aneurysms accounted for 76.81% of 69 sacciform aneurysms in 51 patients ( 85 % ) and eight subtotal occlusion of aneurysms (95 % ～ 99 % occlusion) accounted for 13.56% of total sacciform aneurysms in five patients (8.47%) and four incomplete occlusion of aneurysms ( ＜ 95% occlusion) accounted for 6.78% of total sacciform aneurysms in three patients (5.08%), and one was failure in operation. The rupture of aneurysms occurred during operation in4 patients (6.78%). Two senile patients suffered from intra-opeartive symptomatic thromboembolisn. One patient had stent shifting and spring coil dislocated and moved into the M3 segment of the ipsilateral MCA. Vasospasm occurred in 15 patients during operation, and most of them received endovascular intervention 3 days after the initial ictus. The rate of good recovery was 93.3% at discharge from hospital (the modified Rankin Scales, mRS＜ 2). There were 55 patients followed up for up 24 months after discharge, and excellent recovery rate was found in 51 patients ( mRS ＜ 2), and 3 died.During the follow-up period, no aneurismal recanalization or rupture was noticed in all patients. Conclusions The endovascular intervention is a safe and effective approach to the intra = cranial aneurysms. Advances in the skill of technique and proper management will decrease the complications during operation and improve the prognosis of patients.

Currently, the resistance of first-line anti-tuberculosis drugs has made the prevention and treatment of tuberculosis increasingly difficult, posing a serious threat to global public health. Several studies have shown that efflux pumps are one of the important causes for bacteria to develop multi-drug resistance and extremely-drug resistance, and efflux pump inhibitors can inhibit the efflux of antibacterial drugs, thereby reducing bacterial drug resistance. Numerous natural products and synthetic compounds have been reported to possess efflux pump inhibitory activity, but they have not been applied in clinical settings because of their toxicity, pharmacokinetic properties, etc. Therefore, we summarized the efflux pump inhibitory activity, antimicrobial activity, and structure-activity relationships of reported efflux pump inhibitors against Mycobacterium tuberculosis in recent years, providing references for the development of new efflux pump inhibitors with better activity and lower toxicity.

Objective To compare the efficiency of oscillation with sonication in preparing nano-scale microbubbles (NBs).Methods Nano-scale microbubbles were prepared using oscillation and sonication respectively,and then compared the NBs' size,size distribution,concentrations and time-consumption of the two methods.Results The sizes of nanobubbles prepared by sonication and oscillation were (373.88 ±18.43)nm and (360.74 ± 14.39)nm,respectively.There was no significant difference in size between the two methods (P =0.523).The polidispersity was larger in sonication before centrifugation,there was significant difference between the two methods (P ＜0.001).The concentration of nanobubbles prepared by oscillation was (1.48 ± 0.15) × 1010,which was higher than that by oscillation [(8.07 ± 0.62) × 108],there was significant difference between the two methods (P ＜ 0.001).The consuming time was shorter in oscillation,the difference was significant when compared with sonication (P ＜0.001).Conclusions Both two methods can successfully prepare NBs.Compared with sonication,oscillation can effectively produce NBs with smaller polidispersity,higher concentration and shorter time-consumption.

Objective To explore the correlation of peritumoral brain edema( PTBE)size,histologi-cal grades and the expression rate of Ki-67 in gliomas. Methods The data and specimens about 74 cases of gliomas in People's Hospital of Xinjiang Uygur Autonomous Region during 2010-2013 were collected. All cases were confirmed by surgery and pathology. According to preoperative MRI,PTBE was graded. Immunohisto-chemical discriminate the expression of Ki-67. HE coloration distinguish the histological grades. Results In this study,90. 54%(67/74)patients occured PTBE,the incidence of PTBE inⅠ,Ⅱ,Ⅲ,Ⅳlevel of groups were 100%(3/3),78. 95%(15/19),83. 33%(15/18),100%(34/34). Ki-67 expression was positive in 75. 68%(56/74)patients,and the rates were 0,36. 84%(7/19),94. 44%(17/18),94. 12%(32/34) in Ⅰ,Ⅱ,Ⅲ,Ⅳ level of groups. The expression rate of Ki-67 was 57. 14%(4/7),60. 00%(6/10),and 80. 70%(46/57)in normal group,Ⅰ-level groups of PTBE,Ⅱ-level groups of PTBE. The result of Kruskal-Wallis H showed that the PTBE from different grades was statistically significant(H=11. 304,P=0. 010). The expression rate of Ki-67 in different grade gliomas was statistically significant(H=38. 530,P﹤0. 05), The difference of expression Ki-67 in gliomas of different PTBE was statistically significant( H=6. 478,P=0. 039). The result of Spearman rank correlation analysis showed that the PTBE level increased with the histo-logical grade up in gliomas(r=0. 385,P=0. 001). The expression rate of Ki-67 increased with the histologi-cal grade up in gliomas(r=0. 692,P﹤0. 05),and the expression rate of Ki-67 increased with the degree of PTBE up in glomas( r =0. 256,P =0. 028 ). Conclusion Accorrding to the PTBE size,the histological grades and proliferation ability of glioma can be judged pre-operation. Ki-67 can be used as the indicator of pro-liferation activity of tumor,and also be used as the important basis of histological grades.
