OBJECTIVETo explore clinical outcomes of talus neck fracture treated with mini-plate internal fixation through dual-incision approaches.

METHODSFrom August 2010 to February 2013,18 patients with closed talus neck fractures were treated (10 males and 8 females, aged from 31 to 66 years old with an average of 38.2 years old) with mini-plate internal fixation through dual-incision approaches. According to Hawkins classification, 12 cases were type II and 6 cases were type III. All cases were evaluated with X-ray and 3D CT scan preoperatively to define type and comminuted degree of fractures. Mini-plate fixation with dual-incision approaches was performed after swelling was resolved. X-ray films were taken during following up regularly. Functional evaluation was carried out according to Visual Analogue Scale (VAS), the ankle and hind-foot score of American Orthopedic Foot and Ankle Society (AOFAS). Complications were also recorded.

RESULTSSixteen patients were followed up with an average time of 22.6 months (ranged, 17 to 46 months). No wound infection, skin and flap necrosis or implant failure were found. Traumatic arthritis in subtalarjoint was found in 1 patient. Preoperative VAS (5.94±1.12) was decreased to postoperative (1.06±1.06) (t=27.13, P<0.05). The average AOFAS score was 88.7510.19 at the latest following up; and 11 cases obtained excellent results, 3 good and 2 moderate.

CONCLUSIONMini-plate fixation with dual-incision approaches for talus neck fracture especially for talus neck comminuted fracture, an effective method, could obtain stable fixation, decrease complications.

OBJECTIVETo explore the clinical effect of interference screw and flexor hallucis longus tendon as augmentation material in repair of chronic Achilles tendon rupture.

METHODSFrom September 2010 to June 2012,26 patients with chronic Achilles tendon rupture were treated, including 18 males and 8 females with an average age of 44.2 years old (20 to 66 years old). All patients were unilateral damage. MRI showed the Achilles tendon.ends' distance was 6.0 to 9.0 cm. The postoperative complications were observed. The curative effect was assessed by American Orthopedic Foot and Ankle Society and Leppilahti score.

RESULTSAll the 26 patients were followed up for 18 to 68 months (means 30.4 months). No neurological injury and infection of incision occurred, all patients were stage I incision healing. The shape and function of the ankle were recovered well. The average AOFAS score increased from 52.27±12.30 preoperatively to 90.92±6.36 postoperatively. Leppilahti Achilles Tendon Repair score increased from 34.23±12.86 preoperatively to 90.00±5.10 postoperatively.

CONCLUSIONThe flexor hallucis tendon transfer with an interference screw technique for repairing the chronic Achilles tendon rupture of type IV of Kuwada had advantages of simple operation, quick recovery, firm tendon fixation, and less complications.

Recent advancements on interventional molecular imaging aimed to further complement the advantages of two imaging fields, namely, interventional radiology and molecular imaging. Interventional molecular imaging significantly improved the early diag-nosis of cancer, local treatment, and monitoring of tumor treatments. Interventional radiology has continuously extended the capabili-ties of the currently available molecular imaging techniques to (i) obtain deep-seated targets;(ii) thoroughly examine small targets;(iii) precisely guide the delivery of non-targeted imaging tracers or therapeutics;and (iv) selectively enhance the effectiveness of targeted imaging and treatment with high accuracy. Molecular imaging has been used to guide interventional therapies and assess the thera-peutic efficacies of medical interventions. The continuous efforts on interventional molecular imaging extend molecular imaging from benches or small animal laboratories to large animal suites and ultimately to certain clinical applications in humans and enhance the diagnosis and treatment of cancer.

Objective To investigate the differences of perfectionism in undergraduates with different background. Methods Stratified-random sampling was used to recruit 1 298 undergraduates from two colleges in Chongqing,and Chinese Frost multidimensional perfectionism scale (CFMPS) was applied to survey their perfectionism. Totally 1 245 questionaires were taken back and the response rate was 95.9%. Results There was significant difference of CFMPS score among those who were only child or not in their family (P=0.009),of different performance records (P=0.008) and different mother’s education background (P=0.001). Conclusion Perfectionism is a stable personality,and shows some significant differences among the undergraduates with different background.

The molecular delivery vectors used in gene therapy need provide the features of safety,stability, efficiency and capacity. The current studies on the structure and action mechanism of pRNA, a packaging RNA of phage?29, showed that pRNA with multiple binding sites can through cell membrane easily and escort exogenous molecules to target cell, without inducing immune reaction. As an ideal nano-scale gene therapy vehicle, pRNA presents a promising application in delivering multiple therapeutic components to detect and treat human diseases.

Objective To explore clinical effect and safety of intermittent androgen suppression treatment of advanced prostate cancer in elderly patients.Methods 78 patients with advanced prostate cancer were enrolled,and randomly divided into the observation group and the control group (n=39 each).Patients in observation group were treated with intermittent androgen suppression treatment.Patients in control group were treated with persistent androgen suppression treatment.Results The time of therapy was much longer in observation group than in control group (P＜ 0.001).Quality of life was better in observation group than in control group (P＜0.05).The incidences of adverse reactions including anemia,fever and abnormal liver function were lower in observation group than in control group (all P＜0.05).Conclusions Intermittent androgen suppression treatment prolongs time to androgen-independent progression,improve the quality of life,reduce drug dosage and the incidence of adverse reactions in the treatment of advanced prostate cancer in the elderly.
