Objective To assess the value of embolization of intracranial aneurysms with GDC.Methods 17 patients with 18 intrtacranial aneurysms were treated with GDC.15 patients presented SAH with the following classifications of Hunt and Hess grading:grade Ⅰ and Ⅱ with 10 patients respectively,Ⅲ with 3,Ⅳ with 2.Results 13 patients had excellent clinical outcomes,and 3 patients suffered from transient parlysis after embolization,but recovered following medical treatment medical treatment and one patient died.Conclusion Endovascular treatment of intracranial aneurysms with GDC is a better alternative but a long-term follow-up is necessary.

Objective To compare the clinical effects of 2 common installation positions of the helical blade in the treatment of senile intertrochanteric fractures with proximal femoral nail antirotation (PFNA).Methods From January 2010 to December 2012,166 old patients with intertrochanteric fracture were treated by PFNA.According to the installation position of the helical blade in the femoral head on the postoperative X-ray films,they were divided into a C/C group (87 cases) where the helical blade was at the center of the femoral head in both anteroposterior and lateral views and an I/C group (79 cases) where the helical blade was at the inferior one-third of the femoral head in anteroposterior view and at the center in lateral view.There were no significant differences between the 2 groups in general data preoperation (P ＞ 0.05).The 2 groups were compared in terms of reduction quality,tip-apex distance (TAD),full weight bearing time,fracture healing time,and Harris Hip Score(HHS) at the last follow-up.Results C/C group had 83 patients followed for an average of 13.6 months and I/C group had 76 patients followed for an average of 13.3 months.There were no significant differences between the 2 groups regarding the good-to-excellent reduction rate [94.0％ (78/83) versus 94.7％ (72/76)],full weight bearing time (9.4 ± 1.5 weeks versus 9.3 ± 1.3 weeks),fracture healing time (17.8 ±2.3 weeks versus 17.2 ±2.3 weeks),or HHS (89.6 ±4.6 points versus 89.3 ±4.7 points) (P ＞ 0.05).There was a significant difference in TAD (21.14 ± 3.17 mm versus 24.96 ± 3.48 mm) between the 2 groups(t =-7.242,P =0.000).No infection or cut-out or other related complications of the helical blade occurred in either group.Conclusion The helical blade may lead to satisfactory clinical effects in the treatment of senile intertrochanteric fractures with PFNA no matter at which of the 2 positions it is installed.

To construct a recombinant adenovirus containing CDglyES fusion gene, which can directly inhibit human ovarian cancer cell and indirectly inhibit vascular endothelial cell growth. Methods:We constructed prAdCDglyES using a homolo-gous recombination method in bacteria. The prAdCDglyES was transfected to 293 packaging cells using liposome, in which rAdCDgly-ES was packaged and amplified. MTT was used to observe the proliferation inhibition effect of rAdCDglyES on human ovarian cancer cells and the growth inhibition effect of expressing products of rAdCDglyES on ECV-304. Results:The titer of rAdCDglyES was 1 × 1013.3 TCID50/L, whereas the inhibition rate on human ovarian cancer cell SKOV-3 was (83.1±6.3)%. This result is significantly different from the control rAd-LacZ, which had an inhibition rate of (24.1 ± 13.2)% (P<0.01). The concentrated culture supernatant from cells transfected with rAdCDglyES can inhibit ECV-304 cell proliferation at a rate of (78.7 ± 1.6)%. This rate is significantly different com-pared with that of the control with the same concentration of culture supernatant from cells transfected with rAd-CD, with an effect on ECV-304 cell shown by an inhibition rate of (23.9 ± 9.7)%(P<0.01). Conclusion:The results showed that the recombinant adenovirus rAdCDglyES could inhibit human ovarian cancer cells directly and indirectly.

Objective To explore the clinical characteristics of pancreas damage in children with Henoch-Sch(o)nlein purpura (HSP).Methods The clinical data of 206 HSP patients was analyzed from February 2008 to July 2013.The serum and urine example was detected by the automatic biochemical analyzer and the clinical characteristics of them was analyzed.The pancreatic morphology of patients was observed by type-B ultrasonic,and the clinical feature of skin,joints,digestive tract and kidney damage were observed.The relationship between pancreas damage and other systems damage was analyzed.Results There was 58 cases suffering from pancreas damage in 206 HSP children:31 cases were male,27 cases were female.There was no patients with pancreatic edema and deformation of structure in 58 patients.The incidence of pancreas damage with HSP combined with abdominalgia patients was 39.7％ (50/126),which was obviously higher than that in the patients without abdominalgia 10.0％ (8/80) (x2 =14.355,P ＜ 0.01).The incidence of pancreas damage in mixed type of HSP [31.8 ％ (55/173)] was significantly higher than that in simple type of HSP [9.1％ (3/33)] (x2 =18.292,P ＜ 0.01).The mean hospital stay of the HSP patients with pancreas damage was 6-38 (10.39± 6.80) d,while without pancreas damage was 4-18 (8.51 ± 3.42) d,and there was no significant difference (t =5.790,P ＞ 0.05).Conclusions The HSP children usually combine with pancreas damage.If they have abdominalgia and multi-system damage,they are more likely to be accompanied with pancreas damage,which should be paid more attention.

Objective To explore the clinical application of percutaneous puncture and drainage in treating pyogenic liver abscess. Methods A total of 30 patients with pyogenic liver abscess were treated with ultrasound-guided percutaneous puncture and aspiration of abscess cavity , which was followed by DSA-guided drainage tube placement together with proper washing of abscess cavity. Results Puncturing and flushing of abscess cavity was performed in two patients with < 4 cm liver abscess , and tube placement as well as drainage was carried out in the other 28 patients with > 4 cm liver abscess. No severe complications occurred. Complete cure was obtained in all the 26 patients who had no malignant tumors. Of the 4 patients with malignant tumor, cure obtained in one and death occurred in three. Conclusion Ultrasound-guided or DSA-guided percutaneous puncture and drainage therapy is technically simple, less invasive, highly safe and clinically effective treatment for pyogenic liver abscess.

Objective To investigate the pathogentic factor of severe acute pancreatitis(SAP)-associated lung injury and the protective function of octreotide combined with alinastatin on SAP-associated lung injury in rats.Methods Eighty SD rats were randomly divided into 5 groups.Sham operative(S)group,SAP group,(octreotide)(O)group,ulinastatin(U)group and octreotide + ulinastatin (O+U)group,and each group was divided into 6h,12h sub-groups.After AP models were induced,the serum concentration of amylase(AMY),tumor necrosis factor?(TNF-?),malondiadehyde(MDA),and the concentration of(myeloperoxidase)(MPO) in lung tissue were determined;and the pancreas and lung pathology were graded,the changes of the above-mentioned indexes after using octreotide and ulinastatin were compared.Results(1)Compared to SAP group,AMY,TNF-?,MDA,MPO,and pancreas pathology score were decreased significantly in each of the 3 therapy groups during the same period;and at 12h,in O+U sub-group,lung pathology score also decreased compared to SAP group(P

0.05),but,serum AST and ALT were significantly decreased on the 12th hour in arterialization group(P

[Objective]To investigate the therapy of human enbryonic olfactory ensheathing cells(hOECs) transplantation on adult rats' transected spinal cord.[Method]Separated,cultured hOECS from abortus were obtained and percent age of P75 positive cells was calculated.Twenty-four Wistar rats were choosen and divided into experimental group and control group randomly.All rats of two goups were transected at the T_(10) segment of spinal cord.Nine to ten days later 5 ul(2.5?10~5) hOECs(labled by Hoechst 33342) were injected in the contusion area of lesion site in transplantation group.In control group same volume of DMEM-F12 were transplanted.1,2,4,6,8 and 10 weeks later all rats were estimated by system of the BBB locomotion score respectively.Then part of them were killed.The tissue section of spinal cords were separated and inspected by fluorescence microscope or the methods of immunohistochemical staining.Data were processed with statistical tools in double-blinded condition.[Result]Transplanted hOECs can survive for at least ten weeks and even migrated from the injuried area in spinal cord.From 4 weeks to 10 weeks the BBB locomotion scores of experimental group were improved significantly contrasting to that of control group(P
