OBJECTIVETo investigate the result of hip arthroplasty for failed internal fixation of femoral neck fractures.

METHODSFrom June 2007 to January 2014, 29 cases who underwent hip arthroplasty for failed of internal fixation of femoral neck fractures were reviewed. There were 12 males and 17 females. The mean age was 60.3 years (ranged 43 to 83 years) at the time of the fracture. Left hip was in 16 cases, right hip was in 13 cases. The average interval from fracture to arthroplasty was 23.3 months (ranged, 3 to 48 months).

RESULTSAll of 29 cases were performed total hip arthroplasty. There were 20 cases of cementless cup,7 cases of cementless cup with bone graft, 2 cases of cemented cup with bone graft; 13 cases of cementless stem, 16 cases of cemented stem. There were no complications occurred such as intraoperative fracture of the greater trochanter. The average operative time was (115 ± 38) minutes,the mean intraoperative blood loss was (420 ± 175) ml, the average postoperative drainage volume (240 ± 119) ml, intraoperative blood transfusion was (200 ± 220) ml, intraoperative fluid volume was (2,200 ± 400) ml, the average postoperative blood transfusion was (300 ± 200) ml. There was 1 case get postoperative dislocation. All patients were followed up for 14.7 months in average (ranged, 5 to 24 months). There was no revision for mechanical failure. Harris Hip Score significantly was improved from 51.1 ± 7.5 before the conversion to 88.5 ± 6.4 points at the final follow-up.

CONCLUSIONThe effect of the hip replacement for patients with failed internal fixation of femoral neck fractures was confirmed. This method can shorten the time on the bed and reduce the complications. It benefits the patients earlier functional recovery, but it must control operation indication. The long term efficacy is necessary to further observation.

Objective To explore the optimal management strategies for unresectable advanced pancreatic head carcinoma without preoperative gastric outlet obstruction(GOO).Methods Clinical data of 441 cases of advanced pancreatic head carcinoma without GOO undergoing surgery from Jan 2001 to Dec 2010 were analyzed retrospectively.Results Among the 441 cases of advanced pancreatic head carcinoma without GOO,101 patients received simple Roux-en-Y cholecystojejunostomy (group A),133 patients received simple Roux-en-Y choledochojejunostomy (group B),83 patients received Roux-en-Y cholecystojejunostomy combined gastrojejunostomy(group C) and the other 124 patients received Roux-en-Y choledochojejunostomy combined gastrojejunostomy (group D).The postoperative recurrent obstructive jaundice rates were 7.9％ and 6.0％ in group A and C,respectively; the postoperative de novo GOO rates were 8.9％ and 8.3％ in group A and B,respectively; there were no differences in median survivals among the four groups (F =1.933,P =0.123).Conclusions Choledochojejunostomy is effective for the reduction of recurrent obstructive jaundice for advanced pancreatic head carcinoma patients without GOO,combined prophylactic gastrojejunostomy during surgical biliary drainage could decrease the rate of postoperative GO0.Cholecystojejunostomy could be only applied for patients with poor health or when choledochojejunostomy is a taboo.

BACKGROUND:Dysphagia is one of common early complications after anterior cervical fusion. Medium and severe dysphagia often causes serious influence on the patients. A variety of factors have been shown to have a correlation with the postoperative dysphagia, but specific mechanism is stil unclear. OBJECTIVE:To explore the risk factors for dysphagia after single-level anterior cervical fusion. METHODS:From January 2011 to June 2013, data of 44 patients with dysphagia and 213 patients without dysphagia after single-level anterior cervical fusion were compared. The baseline data (age, gender, ethnicity, body mass index, smoking history, drinking history, hypertension, diabetes, course length, and type of cervical spondylosis) and perioperative data (intraoperative blood loss, internal fixation, the location of the operated level, operation time, and the side of operation approach) between two groups were compared by Logistic regression analysis to determine risk factors for postoperative dysphagia.RESULTS AND CONCLUSION:A total of 257 patients were included with a fol ow-up for 6 to 24 months postoperatively and 44 of them suffered from dysphagia after single-level anterior cervical fusion. The overal prevalence for postoperative dysphagia was 17.1%. Univariate analysis indicated that age, gender, the location of the operated level, and course length were associated with postoperative dysphagia. Logistic regression analysis of multivariate analysis demonstrated that independent predictors for postoperative dysphagia included gender (female), age (>60 years), the location of the operated level (C 4-5 , C 5-6 ), and course length (>12 months). Clinicians should give appropriate recognition and take corresponding measures to avoid it.

OBJECTIVE:To establish a method for full-length cDNA library of Xinjiang Artemisia rupestris. METHODS:Mod-ified Trizol method was adopted to extract total RNA in young leaves of A. rupestris,it was transcribed into single-strand cDNA, and then synthesized into double-strand cDNA by long-distance polymerase chain reaction(LD-PCR)method. PCR product was di-gested by proteinase K and sfiⅠ,and then fractionated by CHROMA SPIN-400 columns. The cDNA longer than 0.4 kb were col-lected and ligated to phage λTriplE × 2,and then protein packaging was performed. Full-length cDNA library was established by SMART technology. 20 monoclonal were randomly selected from the library,and electrophoresis was used to determine the primary library titer,library capacity,recombinant positive rate and length of insert cDNA. RESULTS:The primary library titer was 1.94× 107 pfu/mL,library capacity was 0.97×107 pfu;recombinant positive rate of insert cDNA was 96% and length was 0.5-2.0 kb with an average of 0.9 kb. CONCLUSIONS:The established library is high in capacity and quality,which can provide basis for estab-lishing cDNA library of Xinjiang A. rupestris.

OBJECTIVETo summarize clinical outcomes of locking compression plate (LCP) combined with minimally invasive percutaneous plate osteosynthesis (MIPPO) for the treatment of Pilon fracture.

METHODSFrom January 2009 to December 2012, Pilon fracture patients treated by LCP with MIPPO were retrospectively analyzed. All open fractures, pathologic fractures and those who had limb vascular disease or nerve injury were excluded. Thirty-eight patients were enrolled, including 29 males and 9 females aged from 21 to 78 years old with an average of 48 years old. According to AO classification, 20 cases were type B, 18 cases were type C. Operative time, blood loss, reduction quality, time of fracture healing complications and postoperative ankle joint function were applied for evaluating clinical outcomes, AOFAS scoring were used for assessing postoperative clinical effects.

RESULTSAll patients were followed up from 13 to 24 months (averaged 18 months). All patients obtained bone union without any plate failures or loss of fixation/reduction. One patient occurred superficial wound infection, and resolved with antibiotics and local wound care. Postoperative average AOFAS score was 81 (ranged 65 to 97).

CONCLUSIONLCP with MIPPO for Pilon fratcure has advantages of less invasion, fewer complications and satisfactory ankle function.

Transesophageal echocardiography(TEE) is a new acoustic window to the cardiac structures and great vessels via retrocardiac esophagus. Because of the close relation between the esophagus and the heart, higher transducer frequencies can be applied, therefore leading to improved resolution and more accurate images than transthoracic echocardiography. We describe our experience with the first 353 awake patients. The procedure was well tolerated by the patients and associated with no major complications, within examination 10 to 20 minutes. Clinical diseases which appear to be suited for TEE includes 1) evaluation of native valve diseases, particulary mitral valve, pathologic valvular abnormalities and color Doppler regurgitant flows ; 2) assesment of prosthetic heart valves to better define malfunction and important pathologic associations ; 3) congenital heart disease, particularly atrial septal defect ; 4) endocarditis and detection of vegetations and complications ; 5) detection of thrombus and tumors, size, location, morphology, stalk ; and 6) aortic pathology including atherosclerosis, aneurysm and dissection. We conclude that transesophageal echocardiography is a new imaging technique that is rapidly evolving into a major tool for general cardiac imaging in a variety pathologic conditions and is a safe and useful tool in patients. Future advances in probe technology will continue to expand its applications.
