Objective To analyze the risk factors of failure of internal fixation of unstable femoral intertrochanteric fractures treated with proximal femoral nail anti-rotation (PFNA) in elderly patients,and to provide reference for clinical treatment.Methods Collected the clinical data of 251 aged and unstable femoral intertrochanteric fracture patients who have recieved PFNA treatment from January 2012 to December 2016.Preoperative clinical general data and intraoperative clinical factors were used as analysis variable to analyze the high risk factors and risk factors of internal fixation failure in PFNA treatment by χ2 test ,Wilcoxon rank sum test and Logistic regression.Results Through the analysis of 78 aged patients with internal fixation failure after PFNA treatment,the χ2 test and Wilcoxon rank sum test showed that,type of fractures,osteoporosis Singh index grade, tip-apex distance,application of hormone,basic diseases were risk factors for internal fixation failure after PFNA treatment (P<0.05).Among thses factors,type of fractures,osteoporosis Singh index grade, tip-apex distance were independent high risk factors for internal fixation failure after PFNA treatment(P<0.05).Conclusion Severe type of fractures (type Ⅲ and Ⅳ),osteoporosis of grade 4 to 6,and tip-apex distance greater than 25 mm are high risk factors of failure of internal fixation of unstable femoral intertrochanteric fractures treated with PFNA,and it is better to give more attention and effective intervention or other treatment.

Objective: To evaluate the safety and feasibility of hybrid thoracoscopic surgery and catheter ablation in treating the patients of long-standing persistent atrial fibrillation (AF) with preliminary experience. Methods: A total of 15 consecutive relevant patients treated in our hospital by hybrid thoracoscopic surgery and catheter ablation from 2014-04 to 2016-03 were studied. The average AF time was (4.0±3.9) years including 13 male. All patients received thoracoscopic surgical ablation including pulmonary vein isolation, left atrial (LA) posterior wall isolation, Waterston's groove Ganglionated plexi ablation by bipolar radiofrequency ablation clamp and LA appendage removal, Marshall ligament dividing. Then establishing LA 3D-modeling, based on LA 3D voltage mapping, catheter ablation was conducted to reinforce surgical ablation or modification in order to confirm bidirectional blocking. Meanwhile, LA ridge and mitral isthmus ablation was performed, some patients received LA anterior wall and tricuspid isthmus ablation. The patients were followed-up at 3, 6 and 12 months after the procedure. Results: 13 patients were restored to sinus rhythm after the procedure and no operative complications occurred. The average follow-up time was (12.1±11.5) months. 2 patients with recovered sinus rhythm had re-catheter ablation since atrial flutter at 3 months post-procedure and sinus rhythm was restored. The overall success rate was 86.7% (13/15), no patient had anti-arrhgthmia medication. Conclusion: Hybrid thoracoscopic ablation and catheter ablation have been a minimally invasive, safe and effective method in treating the patients of long-standing persistent AF.

Regarding the needling manipulation, Chifeng Yingyuan, there are different descriptions in ancient medical literature and the current teaching materials or clinical reports, especially for the understanding recorded in Jinzhenfu Poem of Golden Needle). In the current teaching materials and clinical reports, it is described that the needle is inserted deeply at first, and then shallowly; afterward, the needle tip is pushed to the middle layer and manipulated with lifting, thrusting and rotating technique, combined with twisting and flying method. After analyzing the original description in the book and the feasibility of function and operation, the authors introduced their recognition on its manipulation and techniques in this article. This manipulation should be: the needle is inserted to the middle layer, afterward, the needle body is pulled and tilted toward each of the four directions, on this basis, then twisting and flying method is applied.

OBJECTIVETo explore the effect of emodin on endoplasmic reticulum (ER) stress of pancreatic acinar AR42J cells.
METHODRat pancreatic acinar AR42J cells were cultured in 6-well plates, and divided into the normal control group, the model group (with the final concentration at 1 x 10(-7) mol · L(-1) for cerulean and lipopolysaccharide at 10 mg · L(-1)) and the emodin group (10, 20, 40 μmol · L(-1)). Cells in each group were cultured in three multiple pores for 24 h, and their supernate was removed after cell attachment. The normal control group was added with haploids, the model group was added with the modeling liquid for haploids, and the treatment groups were added with different concentrations of emodin at 15-20 min before the modeling liquid. The cells were continuously cultured for 3 h under 37 °C and 5% CO2. Their intracellular protease and lipase expressions were detected with kits. The cellular morphology was observed under optical microscope. The level of calcium in endoplasmic reticulum was measured under laser confocal microscopy. Western blot assay were used to determine the protein expression of ER-related signaling molecules.
RESULTEmodin could significantly inhibit levels of amylase, lipase and intracellular calcium and ER.
CONCLUSIONEmodin could reduce pancreatic acinar cell injury induced by the combination of cerulean and lipopolysaccharide. Its action mechanism is correlated with the inhibition of intracellular calcium overload and ER stress.

Objective To study the characteristics of hepatic artery anatomy and master the method of arterial repair,especially the method and technology of repair of anomalous donor arteries.Methods Sixty-four(human) liver arteries were dissected and repaired,and 31 of these were used in liver transplantation.Results Twelve of 64 cases had anatomical anomaly of hepatic artery(12/64,18.75%).Five of 24 fetal(liver) donors(20.83%) had anatomical anomaly of hepatic artery,one arose from the superior mesentery(artery) as a replaced right hepatic artery,3 from accessory right hepatic artery,and in 1 case the hepatic(artery) arose from superior mesentery artery directly.Seven adults had hepatic artery anomalies:2 cases of right hepatic artery being replaced by artery derived from SMA,2 cases of left hepatic artery deriving from left gastric artery and 3 cases of accessory right hepatic artery derived from SMA.In 31 hepatic(transplantations),4 grafts with anatomical anomaly of right hepatic artery were used.Conclusions (Reconstruction) of hepatic artery plays an important role in hepatic transplantation.Avoidance of injury to(aberrant) hepatic avteries during removal of donor liver is a key to ensure successful arterial repair.During(repair) of very small accessory hepatic arteries,ligation or repair of the artery may be determined after(observation) of backflow from collateral vessels.

Objective To evaluate the safety of coronary intervention using iodixanol in patients with diabetic renal insufficiency.Methods Clinical data of 97 patients with diabetic renal insufficiency undergoing coronary intervention during June 2004 to June 2006 were retrospectively analyzed,50 of them with iodixanol,an iso-osmolar contrast medium (iodixanol group),and 47 with iopromide,a hypotanic contrast medium (iopromide group).Judkin's coronary angiography showed 167 diseased vessels in the patients,65 in anterior descending branches,44 in circumflex branches,and 58 in right coronary arteries. Levels of serum creatinine and blood urea nitrogen were determined before percutaneous coronary intervention (PCI),on the day of the procedure,the 3rd and 7th days after PCI,respectively,as well as radiocontrast media-induced nephropathy (CIN) was observed.Results Totally,192 drug-eluting stents were successfully implanted in 167 diseased vessels,and all patients' angina pectoris symptom disappeared soon after the procedure,with a full success.No acute or subacute stent thrombosis and major adverse cardiac events (MACE) occurred.Two patients (4%) in iodixanol group and 10 (21%) in iopromide group got CIN,with a statistical significance (P
