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.

Objective: To evaluate the prevention and treatment effects of acupuncture-moxibustion for Alzheimer disease (AD) based on various AD mouse models.Methods: Several representative types of mouse models were selected according to the pathophysiological causes of AD, including senescence accelerated mouse/prone (SAMP) mice, soluble amyloid-β protein (Aβ) injection mice/rats, amyloid precursor protein (APP) transgenic mice, and APP/PS1 double transgenic mice. Through the observation of behavioral changes and analysis of core items, the possible mechanisms of acupuncture-moxibustion in preventing and treating AD were explored. Results: Acupuncture-moxibusiton therapy can improve AD mice's cognitive dysfunction; the major action mechanisms including increasing cerebral blood flow, improving the expressions of vital proteins in the hippocampus, preventing neuron cell apoptosis, promoting the clearance of Aβ deposition, activating autophagy pathway to reduce memory deficits and regulating the metabolisms of brain-derived neurotrophic factor, tyrosine kinase receptor B, N- acetylaspartate and glutamic acid. Conclusion: Although the optimal mouse model is not determined, it is sure that acupuncture-moxibustion therapy can improve cognitive function. A more suitable AD animal model should be duplicated in order to better explore the inherent action mechanism of acupuncture-moxibustion in preventing and treating AD.

Objective To observe the clinical efficacy and safety of close-loop muscle relaxant injcction system (CLMRIS) combined with auditory evoked potentials index for monitoring in elderly patients during general anesthesia.Methods A total of 100 patients undergong abdominal operation with ASA Ⅰ-Ⅱ anesthesia in our hospital from February 2012 to October 2012 were selected.Patients were randomly divided into 2 groups:the traditional group (n=50) and the CLMRIS group (n=50).The traditional group was anaesthetized according to clinical experience,and the CLMRIS group was used with the muscle relaxant guided by the close-loop muscle relaxant injection system.The auditory evoked potential (AEP) index and the life index were observed,and the dose of muscle relaxant,the time of consciousness recovery,dynamic response rate during operation and the adverse reaction were recorded at the time points at entering the operating room,induction of anesthesia,tracheal intubation,incision,into the abdominal,exploration,closing abdomen,skin suture,consciousness recovery,tracheal extubation,out of room (T0-T10).Results The vital signs in all patients were stable.The dynamic response rate during operation was lower in the CLMRIS group than in the traditional group at each time points of T8-T10 (all P＜0.05).There was no increase in mean artery pressure (MAP) and heart rate in groups at the time points of T0-T1,T8-T10 (all P＞0.05).The time of tracheal intubation,tracheal extubation and consciousness recovery were shorter in the CLMRIS group than in the traditional group [(268±30.4) min vs.(172±23.7) min,(14±6.4) min us.(18±7.9) min,(8.8±2.9) min vs.(12.2±4.6) min,respectively,t=3.277,6.341,3.346,all P＜0.05].There were no significant differences in AEP index between groups at the time of T0 (P＞0.05),but at the time of T1,the AEP index was lower in CLMRIS group than in the traditional group (P＜0.05).Conclusions The application of close loop muscle relaxant injection system can improve the safety of general anesthesia in the elderly and reduce the incidence of postoperative residual paralysis.The CLMRIS combined with the auditory evoked potential for monitoring depth of anesthesia can prevent and reduce the incidence of intraoperative awareness,has a strong controllability in general anesthesia with smooth induction,and can reduce the dose of anesthetic drugs to achieve the best anesthetic effect.

The NSP2 gene of porcine reproductive and respiratory syndrome virus (PRRSV)S1 strain was partly amplified and cloned into a prokaryotic expression vector pGEX-6P-1 and a fusion protein GST-tNSP2 with molecular weight of 50 kDa was expressed in E.coli. The purified GST-tNSP2 protein showed a strong reaction with the PRRSV-positive sera in Western blot assay. Balb/c mice were immunized with the purified protein, and the splenocytes of the immunized mice were fused with murine myeloma cells SP2/0. After subcloning by 3 times, two hybridoma clones which produced McAbs steadily were screened by ELISA, named 3H3 and 2B5. They all reacted strongly with the PRRSV S1 infected Marc-145 cells in IFA, but not with the PRRSV SY0608 strain. Both of the McAbs belong to IgG1 isotype, and their light chains belong ? type. The expressed GST-tNSP2 protein and McAbs could be used for identification of PRRSV isolates and functional analysis of NSP2.
