Objective To study the ways,mechanism,indication,curative effect of " Basket" skill applied in the interventional therapy for intracranial aneurysm. Methods Intracranial aneurysm with 1 : 1 ≥ neck/body ≥ 1 : 2 ," 3 D coil" was used to form a basket in it;in that with 1:2 > neck/body,common "2D coil" was applied. And the following coils were applied with hydrocoil or fibered coil combined with common platinum coil to increase the embol-ism density. Results In 156 cases with 158 aneurysms,143 aneurysms were 100% embolized (90. 5% ) ;131 ca-ses discharged with GOS 5 score(84.0% ),and 2 cases died ( 1.3% ). Conclusion " Basket" skill can increase the embolization density in aneurysm,reducing the residual of the neck,getting embolizated fully and improving the prognosis.

Objective To investigate the effect of aspirin on the incidence of thromboembolism in hypertensive patients associated with paroxysmal atrial fibrillation.MethodsFour hundred hypertensive patients with paroxysmal atrial fibrillation (mean age 59 years) free of thromboembolic events were randomized assigned to receive aspirin (0.3 g/d) or placebo. Cerebral thromboembolism,including transient ischemic attack and embolism of peripheral arteries were defined as primary outcomes. Event-free survival curves were estimated by Kaplan-Meier curve. Results During 3.6 years follow-up,primary outcomes occurred in 61 patients (4.3% per year). Aspirin significantly reduced the incidence of primary outcome as compared with placebo group( 9.0% vs 21.5%,P

Objective To investigate the combined use of osteoarthritis treatment effect of lornoxicam and peptide drugs.Methods 260 patients with osteoarthritis treated in our hospital from May 2014 to June 2016 were selected, were randomly divided into study group and control group, each group of 130 cases.The patients in the control group were treated with sodium hyaluronate and lornoxicam, the study group was given bone peptide on the basis of the control group. The pain scores, knee function and adverse reactions were compared between the two groups.Results There was no significant difference in VAS and WOMAC scores between the two groups before treatment; after treatment, the improvement of VAS and WOMAC score in the study group was better than that in the control group (P<0.05). There was no significant difference in the incidence of adverse drug reactions between the two groups. Conclusion Sodium hyaluronate, bone peptide, lornoxicam and other drugs in the treatment of patients with osteoarthritis clinical efficacy is obvious, and fewer adverse reactions.

AIM:To observe the situation of rat retinal tissue DNA damage at early diabetic period, discuss the role of the blood glucose fluctuations, and provide a new method for studying the pathogenesis of diabetic retinopathy ( DR) .
METHODS: SD rats were randomly divided into four groups:normal control group (NC), normal fluctuation group ( NF ) , diabetes group ( DM ) and diabetes fluctuation group ( DF ) . Diabetic models were established through intraperitoneal injection of STZ. A certain amount of glucose was injected in the rats of group NF and DF in an intraperitoneal mode three times a day after the model was established, thereby causing blood glucose fluctuations. Rats were killed and the retinal tissues were taken in the 8th week. Single cell gel electrophoresis ( SCGE ) technique was adopted for detecting DNA injury extent in the retina tissue.
RESULTS:Groups NF and DF showed significant and regular fluctuations. The curve of blood glucose fluctuations was relatively stable. All values of MBG, SDBG, LAGE and M were significantly increased compared with group NC. Group DF was increased more significantly. It was statistically significant (P<0. 01). SCGE showed that there were DNA damages in different levels in the cells of group NF, DM and DF. Indicators of cells such as TL, TDNA %, TM, OTM were higher than that in group NC. It was statistically significant ( P<0-01). The comparison difference between two groups was also significant (P<0. 01).
CONCLUSION: Rat retinal tissues have DNA injury during early diabetic period. DNA injury is gradually aggravated with blood glucose fluctuation. It indicates that high blood glucose and blood glucose fluctuation are involved in the mechanism of cell DNA injury, and they may be one of DR early event, have played a certain role in the incidence of DR.

Objective To study whether the leakage of polymethylmethacrylate (PMMA) can lead to pulmonary embolism in vertebroplasty (VP), and to observe the correlation of embolism degree with the doses of PMMA. Methods Fifteen canines were randomly divided into 3 groups: group A, B, C, and were injected 0.5, 1.0, 2.0 ml PMMA into the femoral veins, respectively. Before and after the injection, chest CT and angiography of pulmonary artery were performed, the pressure of pulmonary artery was measured, and the blood gas analysis of femoral artery was done. At last, the canines were euthanized and examined and histologically after HE-stained. Results In group C, the pressure of O_2 decreased obviously, and significant difference was found between before and 10 min after injection (P<0.05). The pressure of CO_2 increased quickly in group C, significant difference was detected between before and 1 min after injection (P<0.05). Pressure of pulmonary artery in both group B and C were significantly different between before and after injection (P<0.05). Conclusion The leakage of PMMA can lead to pulmonary embolism. The degree of pulmonary embolism is correlated to the doses of PMMA. The large dose of bone cement leakage can lead to disorder of respiratory function.

Objective To compare the effect of proximal femoral intramedullary nail fixation and femoral retrograde intramedullary nail combined with hollow lag screw fixation in the treatment of ipsilateral femoral neck and shaft fractures.Methods Data of 42 patients with ipsilateral femoral neck and shaft fractures who were admitted in our hospital from January 2007 to January 2016 were retrospectively analyzed.According to different fixation methods,the patients were divided into two groups:single intramedullary nail group (SIN group) (20 cases,treated with single proximal femoral intramedullary nail,15 males and 5 females with an average age of 39.4);combined internal fixation group (CIF group) (22 cases,treated with femoral distal intramedullary nail combined with femoral neck hollow lag screw,17 males and 5 females with an average age of 42.2 years).In the SIN group,4 cases were type A,9 cases type B,7 cases type C according to AO classification.And 14 cases belonged to Ⅰ or Ⅱ (stable fracture),6 cases of type Ⅲ or Ⅳ (unstable fracture) according to Garden classification.In the CIF group,3 cases were type A,10 cases type B,9 cases type C according to AO classification.And 16 cases belonged to type Ⅰ or type Ⅱ,6 cases type Ⅲ or Ⅳ according to Garden classification.The incision length,operation time,intraoperative blood loss,fracture healing time,postoperative weight time,stability of internal fixation,hip function score,pain in the knee and postoperative complication rate were compared between the two groups.Results There was no significant difference in gender,age and fracture classification between the two groups.The operation time (75.0±10.2 min),intraoperative blood loss (150.6±80.4 ml),hip Harris score excellent rate (80％) of incidence of knee pain in postoperative 3 months (10.0％) of the SIN group were significantly lower than those of the CIF group (105.2±18.4 min,180.0±56.8 ml,86.4％ and 31.8％).The length of incision (8.3±1.4 cm) in the SIN group was significantly longer than that in the CIF group (4.0±0.6 cm).There was no significant difference in fracture healing time (SIN group 20.O±4.0 weeks,CIF group 19.6±4.2 weeks) and postoperative weight time (SIN group 8.2±4.0 weeks,CIF group 8.0±4.2 weeks) between the two groups.The main complications of the two groups were delayed union (3 cases of SIN group and 1 case of CIF group),nonunion of fracture (1 case of SIN group) and,coxa vara (1 case of SIN group).The complication of SIN group (30％) was significantly higher than that of CIF group (4.5％),which occurred mainly in unstable femoral neck fracture cases.Conclusion Both proximal femoral intramedullary nail fixation and femoral retrograde intramedullary nail combined with hollow lag screw can effectively treat femoral ipsilateral femoral neck and shaft fracture.Femoral retrograde intramedullary nail combined with hollow lga screw has more therapeutic advantages for unstable femoral neck fractures (Garden Ⅲ and Ⅳ).

Objective To investigate the value of 18F-FDG PET/CT in the phasing and grading of renal cell carcinoma (RCC) complicated with vena cava tumor thrombus (VCTT).Methods From December 2011 to September 2015,a total of 72 patients (52 males,20 females,age:36-74 years) were enrolled in this retrospectively study.All patients underwent 18F-FDG PET/CT and contrast-enhanced CT studies,and were diagnosed as RCC.The RCC patients combined with VCTT were classified by Mayo-level.Wilcoxon rank sum test was used to compare the grading of VCTT by PET/CT and contrast-enhanced CT.NM staging on abdominal area level was performed and the results were compared with x2 test.Results VCTT was identified in 18 RCC patients and the grading results by PET/CT were as follows:9 cases in Level 0,4 cases in Level Ⅰ,2 cases in Level Ⅱ,1 case in Level Ⅲ,and 2 cases in Level Ⅳ.When evaluated by PET/CT,20 cases were in N0M0,21 were in N1M0,9 were in N0M1,and 22 were in N1M1.NM staging results by contrast-enhanced CT were as follows:50 cases in N0M0,10 in N1M0,10 in N0M1,and 2 in N1M1.In addition,2 N1 and 2 M1 were found by the whole body PET/CT.The classification results of VCTT and staging of abdominal level by PET/CT were significantly better than those by contrast-enhanced CT (z=-2.462,P＜0.05;x2=32.806,P＜0.01).Conclusion 18F-FDG PET/CT is not only valuable for detecting primary RCC and local metastasis,but also useful for finding where the VCTT extends,which is conducive to therapeutic planning and further clinical treatment.

Objective To explore the relationship between the expression of EIIIA + fibronectin in incised wound of rat’s skin and injury time. Methods The wounding model was established by cutting the dor-salskin of 48 adult SD rats. The rats were sacrificed atthe pre-setinjury time as immediately, 0. 5h, 1h, 2 h, 3 h, 4 h, 6 h, and 8 h. The skin sam ples were taken at the m argin of wound. The expression of the EIIIA + fibronectin was detected by im m unohistochem istry and W estern blotting and the relationship be-tween its expression and injury time was observed. Results The expression of EIIIA + fibronectin was not observed im m ediately. The basal cell of skin began to showpositive expression 0. 5 h after injury. W ith the extension of injury time, positive staining became stronger. The value of relative optical density was gradually increased with prolonged injury time by the W estern blotting analysis. Conclusion The expres-sion of EIIIA + fibronectin could be used for estimation of injury time in the early stage of skin injury.

Objective To evaluate combination of cholcdochoscopy or duodenoscopy with therapeutic laparoscopy (LCDCS) in treatment of detail choledochus stones. Methods Laparoscopic cholecystectomy was firstly performed and followed by choledochoscopy or duodenoscopy. Procedures of therapeutic choledochoscopy were as follows: choledochoscopic exploration via cystic duct remnant, choledochotomy, electrohydralic lithothipsy, drainage of bile duct with ureteral catheter via cystic duct remnant, T-tube drainage, or the suture of duct incision. Procedures of therapeutic duodenoscopy were as follows: access to the common bile duct and duodenum through ureteric catheter and zebra guidewire via cholecystic duct remnant, duodenoscopy via oral cavity into the duodenum papilla, papillotomy with needle-knife or arch-like electro-knife along the ureteric catheter or zebra guidewire, and stone clearance in the common bile duct with the reticulation and balloon of duodenescopy. Results Combination therapy were given to 191 cholelithiasis patients with detail choledochus stones. Combined choledochoscopy were performed in 117 patients. Stones were completely removed and average operation time was 114 min. Bile leakage occurred in 7 cases, but was cured with drainage. Postoperative imaging showed 2 cases of bile duct stenosis at primary closure of duct incision. Combined duodenescopic procedures were performed in 74 patients. Papillotomy and stone clearance were successfully performed in 68 patients, 5 others of whom underwent successful papillotomy only, and another underwent other operations. Average operation time was 97 min. Post-operation mild acut pancreatitis developed in 6 patients.
