Objective To compare the treatment effects of senile intertrochanteric fracture with the dynamic hip screw(DHS),proximal femur locking compression plate (LCP),anti-spin femur proximal femoral nail(PFNA).Methods Ninety cases of femoral rotor fracture patients were treat in our hospital from September 2010 to March 2012 by DHS(n =30),LCP(n =30) and PFNA(n =30) treatment of femoral intertrochanteric fractures.We compared the surgical time,blood loss,fracture healing time,postoperative complications and hip function scores.Results In DHS,LCP and PFNA group,the blood loss ((287.1 ± 72.0) ml,(214.9 ± 65.8)ml,(85.0 ± 33.6) ml,F =88.7,P < 0.05),the operative time ((1.51 ± 0.07) h,(1.49 ± 0.04) h,(0.70 ±0.10) h,F =445.8,P < 0.05),and both were significant difference.But the fracture healing time ((15.2 ±1.7) weeks,(17.0 ± 1.4) weeks,(15.9 ± 1.8) weeks,F =1.4,P > 0.05),there was no significant difference.The PFNA group had a good hip Sander' score of 96.7%,better than other two groups (87.5%、96.8%) (x2 =39.06,P <0.05).The weight-beating time of PFNA group is earlier than the other two groups ((1.00±0.36) cm,(0.80±0.12) cm,(0.60±0.19) cm,F=30.4,P<0.05).Conclusion PFNAinthe treatment of femoral intertrochanteric fracture has advantages in minimally invasive,less blood loss,and help patients go through the perioperative period.

Objective To explore the relationship of the changes of memory behavior and the of changes of the parameter of synapse structure in the brain cortex and hippocampus of chronic cerebral hypoperfusion rats Methods Chronic cerebral hypoperfusion rat model was established by ligating bilateral common carotid arteries of the old rats (over 12 months) The rats were divided into 3 groups, normal, 2 months ischemia, and 4 months ischemia groups The memory behavior changes were observed with a computerized shuttle training case The ultrastucture of synapse were observed with electron microscopy for the number density, length of activity cord, area of synapses disk, surface density of the synapse, and the results were analyzed with stereology and image analyses The relationship between the behavior and the ultrastructure were studied Results Active avoidance response (AAR) and passive avoidance response (PAR) were decreased in the 2 months ischemia group and the 4 months ischemia group The number density (Nv) of the synapses in the brain cortex and hippocampus were reduced in the 2 months ischemia group and the 4 months ischemia group The length of activity cord (L), the area of synapses disk (S), the area density (Sv) in the hippocampus decreased in the 2 and 4 months ischemia group, and those in the brain cortex did not change in the 2 groups Conclusion The decrease of the number density (Nv) and the length of activity cord (L) of synapses in the chronic cerebral hypoperfusion is related to the memory behavior changes

Objective To explore colloidal gold method used to detect fecal occult blood tests(FOB)detection capability and establish the laboratory standard operation of detecting FOB limit of blank(LOB),limit of detection (LOD)and quantifica-tion limit (LOQ)according to the CLSI document《Evaluation of Detection Capability for Clinical Laboratory Measurement Procedures;Approved Guideline-Second Edition》(EP17-A2),in order to reduce the false negative rate of the weakly positive samples,and to provide a way of quantitative detection for qualitative detection of colloidal gold method.Methods Detected series of solution of hemoglobin made of dissolved fresh whole blood with the ELISA kit of human free hemoglobin,and es-tablished the standard curve of detection of FOB with colloidal gold method.Detected the blank samples and a series of low concentration samples with the colloidal gold test strip of FOB and measured the color bands by the Nato Checker710.The quantitative results obtained were statistically analysised by SPSS 1 9.0 and calculated blank limit,detection limit and quanti-fication limit.Results The LOB,LOD and LOD were 99.01,340.48 and 354.9 ng/ml according to the methods in CLSI EP1 7-A2 ducument.Conclusion The detection limits established by CLSI EP1 7-A2 document was more scientific in j udge-ment positive or negative to FOB than which used naked eye and can meet the clinical laboratory and clinical doctor require-ment better.Clinical laboratories should be strictly in detection limits of reagents in order to ensure their effectiveness,and should be generaly to other tests based on colloidal gold method.

Objective To investigate the change of quality of life and urodynamics after the enterocystoplasty combined with clean intermittent self-catheterisation (CISC) in nonparalytic spinal cord dysfunction (NSCD) patients with neurogenic underactive bladder by the Medical Outcomes study 36-item short-form general health survey (SF-36). Methods The quality of life of 72 NSCD patients with NUB were measured by SF-36 questionnaire, who had been taken enterocystoplasty combined with CISC or only CISC according to urodynamic results. In total, 58(81% ) patients were successfully followed for one year by SF-36 questionnaire and urodynamic examination, including 30 men (mean age 27±5 year) and 28 women (mean age 26±4 year). The normal volunteers without lower urinary tract symptom were set as control group, including 20 men (mean age 28 ± 4 year) and 20 women (mean age 29±4 year). Results At the follow-up, physical role, vitality and social function of men and women were 55±14 and 45±15, 76±19 and 74±15, 52±19 and 59±13 respectively, significantly higher than those before the treatment (35 ± 10 and 32 ±11, 27 ± 18 and 33 ± 17, 40 ±12 and 34 ±15). The bladder compliance and maximum cystometric capacity were (320 ± 44 ) ml and ( 338 ±50)ml,(55±15)cm H2O and (60±17)cm H2O respectively, also significantly higher than those before the treatment (131±30ml and 140±35ml,5±3 cm H2O and 6±4 cm H2O). However, detrusor leakage point pressures were (6±2)cm H2O and (6±3)cm H2O respectively, significantly lower than those before the treatment (28 ±9 cm H2 O and 25 ± 6 cm H2O). Except for physical function and bodily pain, the all domains of quality of life in both men and women patients were significantly lower than those in control group. Only 17 % of men and 7 % of women believed "their health is better than that one year ago". There was no significant difference in the remission rate between men and women (89% vs 76%) in the patients with RUUTD before treatment. Conclusions It is suggested that urodynamic parameters are significantly improved. Many domains of quality of life were not improved and the reduced quality of life still occurred in NSCD patients with NUB using enterocystoplasty and CISC.

Objective To evaluate the feasibility and safety of establishing benign proliferative esophageal stenosis model by using stent implantation in experimental rats.Methods A customized self-expanding,metallic and straight tubular stent was used in this experiment (5 mm in diameter and 15 mm in length),on both sides at the stent's middle part there was a protruding barb that was used as a fixation device.Twelve healthy Sprague Dawley (SD) rats were randomized divided into group A (blank control group) and group B (stent implantation group),with 6 rats in each group.Esophageal stent implantation was employed in the rats of group B,and esophageal radiography was separately performed immediately,one and 4 weeks after stent implantation.All the experimental rats were sacrificed 4 weeks after stent implantation.The normal esophageal tissue of the rats in group A and the esophageal tissue at stent site of the rats in group B were collected and sent for pathological examinations,including gross morphology,light microscopy,etc.Results Successful stent implantation was achieved in all rats of group B,and the esophageal radiography performed immediately,one and 4 weeks after stent implantation showed no esophageal stent displacement;no severe complications occurred during the operation or follow-up period.Compared with group A,esophageal radiography reexamination performed 4 weeks after stent implantation in group B revealed that esophageal stricture at stent segment,caused by benign tissue hyperplasia,could be observed.The esophageal stent segment was taken out,its lumen was obviously narrowed under gross observation,and typical benign hyperplasia could be seen under optical microscope examination.Conclusion Using esophageal stent implantation to establish esophageal stenosis model is safe and feasible in experimental rats.The use of esophageal stent with barbs can significantly reduce the incidence of stent displacement.
