Objective To explore feasibility and clinic results of the MIPPO (minimally invasive percutaneous plate osteosynthesis) technique in treatment of humeral fractures. Methods 14 patients with humeral fracture underwent the MIPPO operation in our department. 7 of them were injured in a traffic accident, 4 in sports and 3 in daily life. There were 11 males and 3 females, with their ages ranging from 16 to 72 years. Of the 14 cases, 9 were proximal ones and 5 mid- distal ones, 3 were multiple injuries and 1 pathological fracture. Results The average intra- operative time was 80 minutes (ranging from 55 to 130 minutes). No patient received blood transfusion. The intra- operative blood loss was 100 to 200 mL. 14 cases were followed up for 8 weeks to 14 months. Their cuts healed at the primary stage. Their shoulder and elbow functions were fine. The fracture segments got satisfactory reduction with good apposition and alignment radiologically. The callus appeared 4 to 8 weeks postoperatively. Conclusion MIPPO is a safe and effective treatment for the humeral fracture with the benefits of less invasion, fewer complications and higher union rate.

Objective To validate the technique and establish the reference jitter values in voluntarily activated extensor digitorum communis using a concentric needle electrode (CNE) in healthy Chinese adults.Methods From January to August 2013,forty-two Chinese subjects from healthy examination center of our hospital were prospectively studied,including 20 males and 22 females.Routine electromyogram was tested and jitter was recorded with CNE in all subjects.The jitter values of action potentials pairs of muscle fibers were expressed as the mean consecutive difference (MCD) after 20 analyzed potential pairs.Results The mean MCD of 42 subjects was (23.0 ± 3.1) μs ranging from 17 to 32 μs.The mean jitter value of all 840 potential pairs was (22.8 ± 7.5) μs ranging from 8 to 54 μs.Upper 95％ confidence limits for mean MCD and individual MCD were 29.2 μs and 37.8 μs,respectively.The mean value of MCD of 20 males and 22 females were (23.2 ± 2.8) μs and (22.8 ± 3.4) μs,respectively.There was no statistic difference between genders in MCD (t =0.44,P =0.66).There was no correlation between age and MCD (r =0.11,P =0.48).The mean value of mean interpotential interval was (802 ± 139) μs ranging from 541 to 1 160 μs.Conclusion The present study confirms the suitability of jitter analysis with CNE,which can serve as an objective and valuable method for testing the function of neuromuscular conjunctions.

Objective To investigate the head and neck CTA findings and cerebral CTPI in patients with transient ischemic attack (TIA),and their relationship with frequency of TIA,duration and CTA detected responsible vessels.Methods 180 TIA patients were selected as the research subjects,the GE Lightspeed 64 spiral CT perfusion CT scan and CTA examination were taken,and the differences in CTPI parameters measurement,head and neck artery disease of patients were analyzed.To observe the correlation between CTPI perfusion abnormalities in patients with TIA seizure frequency,duration and NIHSS score.The CTPI perfusion abnormalities and consistency of CTA display of responsible vessels were analyzed.Results The positive rate of CTPI examination was 75.56％,that of CTA examination was 81.11％.The positive rate of patients(NIHSS ≥4 points) with CTPI was 88.89％,which was higher than 66.67 ％ in patients (NIHSS ＜ 4 points) with CTPI (x2 =6.87,P ＜ 0.05).The positive rate of patients (seizures time ≥ 10min) with CTPI TIA was 71.43％,which was higher than 45.45 ％ of the patients (seizures time ＜ 10m in) with CTPI (x2 =7.23,P ＜ 0.05).The CTPI positive rate of patients with the TIA seizure frequency ≥ 2 times/d was 83.33％,which was higher than 61.67％ of patients with the seizure frequency ＜ 2 times/d(x2 =5.48,P ＜ 0.05).The CTPI positive and CTA responsibility vascular consistent proportion was 73.33 ％,which was significantly higher than 26.67％ of both inconsistent and negative (x2 =19.43,P ＜ 0.01).Conclusion The cerebral CTPI and head and neck CTA can response to TIA in patients with intracranial lesions accurately,consistency and clinical manifestations are very good,which have higher value in clinical application.

Objective To investigate the clinical efficacy of statins atorvastatin calcium on cerebral carotid atherosclerotic plaques in patients and the effects on C-reactive protein .Methods 76 patients admitted to hospital with cerebral carotid atherosclerotic plaques in patients randomized manner using its divided into the observation group and control group of 38 patients in the control group not using statins , given only hospital conventional therapy , observed in the control group were given atorvastatin group based on calcium statin treatment ,post-treatment comparison groups the size of carotid atherosclerotic plaque and plasma C-reactive protein changes .Results After treatment , plaque size(0.069 ±0.021)cm2,IMT was (1.29 ±0.28)mm,significantly less than before treatment,after treatment difference was statistically significant (t=7.538,7.132,all P<0.05)also significantly less than the control group ,the difference was statistically significant (t=7.131,6.372,all P<0.05);the observation group after treatment C-reactive protein(3.54 ±1.92 ) mg/L, significantly lower than before treatment , before and after treatment difference was statistically significant(t=6.831,P<0.05),and significantly lower than the control group ,the difference was also statistically significant(t=7.125,P<0.05).Conclusion For patients with cerebral carotid atherosclerotic plaque is concerned,the application of atorvastatin calcium treatment can not only effectively reduce plaque area , but also reduce C-reactive protein,and therefore worthy of further clinical application .

Objective To explore the clinic results of the locking compression plate fixation for injuries at the posterior ring of pelvis. Methods 5 patients with injuries at the posterior ring of pelvis were treated with locking compression plate fixation. 2 of them resulted from crashing, 2 from crushing and 1 from falling. They included 4 males and 1 female and their average age was 35.6 years. According to AO classification system, there were 1 type B1, 2 type B2, 1 type B3 and 1 type C1; according to Dennis classification system, there were 4 section I fractures and 1 section II fracture. Results All the patients were available at follow-up, with a mean period of 5.8 months (ranging from 3 to 12 months). The average intraoperative time was 50 minutes (ranging from 30 to 80 minutes), and no patient underwent blood transfusion because the intraoperative blood loss was only 100 to 400 mL. There was no iatrogenic nerve injury and all the incisions healed during the primary procedure. The function and sense of sacroiliac joint and low extremities recovered to normal. Conclusion The locking compression plate fixation is one of the effective methods for treatment of injuries at the posterior ring of pelvis, for it is simple and minimally traumatic, and has a low rate of complications.

Objective To study the protection of Kangnaoling capsule to free radical injury and influence on the expression of caspase-3 and Bcl-2 in neuron of VD rat. Methods VD rat model was duplicated. Using spectrophotometry to detect contents of SOD, MDA and NO, spectro-fluorimeter to detect the expression of caspase-3, spectrophotometric method to detect the expression of Bcl-2 after traditional Chinese medicine interference. Results Kangnaoling capsule can markedly reduce the contents of MDA, raise contents of SOD and NO, degrade the expression of caspase-3, enhance the expression of Bcl-2. Conclusions Kangnaoling capsule can markedly protect VD rat from free radical injury, which probably correlated with increasing expression of Bcl-2, decreasing expression of caspase-3.
