Objective To analyze the mechanical mechanism of suburethral slings by measuring the mechanical properties of female pig urethra wall and polypropylene mesh.Methods The uniaxial tension tests of 49 female pig urethra wall strips and 27 polypropylene mesh samples were performed to test the mechanical properties.Results The stress and strain of urethra wall displayed a parabola shape and its elastic modulus was proportional to the square root of stress as well as the strain.The maximum calculated elastic moduli of the urethra wall were 0.806 MPa and 0.818 MPa correspondingly calculated with stress and strain.The elastic modulus of polypropylene mesh was(6.977?1.095) MPa.The ultimate stress of polypropylene mesh was significantly higher than that of the urethra wall,and the ultimate strain of polypropylene mesh was significantly lesser than that of the urethra wall.The calculation results suggested that the suburethral slings treatment of poly-propylene mesh decreased the deformation to 1/3 of the untreated stress urinary incontinence.Conclusion Polypropylene mesh has special mechanical properties that suit suburethral slings and enhance the support to the urethra,and improve the continence.

Objective To discuss the value of laparoscopic total extraperitoneal repair(TEP) for inguinal hernia.MethodsBetween 2005 and 2007,82 consecutive patients with inguinal hernia at 97 sides underwent TEP by laparoscopy in our hospital.Among the cases [76 men and 6 women with a mean age of 52 years(21 to 88)],9 had unilateral direct inguinal hernia,50 showed unilateral indirect inguinal hernia,and 9 suffered from bilateral indirect inguinal hernia,6 cases were found having bilateral indirect inguinal hernia complicated with direct hernia,and 8 were recurrent cases of indirect inguinal hernia.Results In the patients,5 showed massive postoperative abdominal adhesion;one of them was converted to open surgery because of severe injury to the peritoneum,the other 4 were treated by continuous suture using 5-0 absorbable thread.The operation time for laparoscopic surgery ranged from 30 to 180 minutes(58 minutes for unilateral operation,and 97 minutes for bilateral operation on average).No patient needed analgesics after the procedure.The mean hospital stay for this series was 7 days(range: 4 to 12).Nine patients developed seromas of the scrotum,and was then cured by local drainage and physical therapy.The 82 patients were followed up for 13 to 38 months with a mean of 26 months,during which no one had recurrence.Conclusion As a safe and minimally invasive procedure,which leads to less trauma and pain,as well as quick recovery,TEP is especially suitable for patients with recurrent or bilateral hernias.

Objective To investigate the effects of three different motor training regimens on motor function improvement after spinal cord injury (SCI) in rats.Methods Forty-five healthy,adult Sprague-Dawley rats (female),weight 260-300 g,were included.Six rats were selected as the normal group.A model of incomplete SCI at the T9 level was induced in the others using a modification of Allen's method.Nine rats died after the injury and were excluded.The other 30 rats were randomly divided into 5 groups:a 7 d control group,a 35 d control group,a bodyweight-supported-treadmill-training (BWSTT) group,a swimming training group and a wheel running group,with 6 rats in each group.The three training groups began exercising at the 8th day post surgery,30 min per day,5 days a week for 4 weeks.Locomotor function was evaluated by inclined plane tests,modified Tarlov scores,and the BassoBeattie-Bresnahan (BBB) scale before the operation and on the 1st,7th,14th,21st,28th,and 35th day post surgery.Histomorphological changes of the T9 level spinal cord and the gastrocnemius muscle were observed with light microscopy and electron microscopy,and the cross sectional areas and diameters of the gastrocnemius muscle fibers were calculated.Results ①In the BWSTT group and the swimming training group,locomotor function scores increased significantly at all time points compared with the two control groups.There was no significant difference in rehabilitative effect between the BWSTT group and the swimming training group.But compared with both control groups,improvement in the wheel running group was not significant.②After 4 weeks of training,histomorphological observation of the injured T9 spinal cord tissue and gastrocnemius muscle fibers showed that the improvement in the BWSTT group was the most significant.The edema of the injured T9 level spinal cord tissue had decreased,cell vascular degeneration had lessened,the morphology of the neurons and glial cells trended to perfect recovery and nerve fibers had proliferated significantly.③Comparing the cross sectional areas and diameters of gastrocnemius muscle fibers showed that the improved amyotrophy in the BWSTT group was the most significant.The average cross sectional area (55.34 + 14.46 μm2) and diameter (8.32 + 0.99 μm) were close to the normal group (55.49±13.84 μm2 and 8.37 +1.13 μm).The swimming training group also had great improvement (46.05±8.50 μm2 and 7.68 + 0.76 μm) compared with the 35 d control group,while improvement in the wheel running group was not significant.Conclusions All three motor training regimens can improve locomotor and neurologic function,but the effects of BWSTT and swimming are better than that of wheel running.

Objective: To study the biotransformation of Poria cocos by Ganoderma lucidum and the changes of total polysaccharide and total triterpenes contents of the biotransformation products. Method: The experiment uses the microwave method to extract and sulfuric acid-phenol method to measure total polysaccharide content. And the ultrasonic wave method was used to extract total triterpenes and the content was measured by vanillin-perchloric method. Result: After treatment by G. lucidum, the total polysaccharide and triterpenes content of the biotransformation products were significantly higher than the non-conversed P. cocos (P<0.01), showing that the original performance of P. cocos was changed by way of biotransformation of G. lucidum; P. cocos had a promotion effect on the growth of G. lucidum. Conclusion: Biotransformation of P. cocos for Increasing the total polysaccharide and triterpenes contents by using G. lucidum has advantages of simple, low cost and so on. This method has a certain application value in modernization of Chinese traditional medicine.

Objective To investigate the neuropathic pain (NP) accompanying spinal cord injury (SCI),and to analyze the related factors to provide references for its prevention and treatment.Methods Seventy SCI patients with NP were selected using the DN4 scale.Their age,gender,occupation,education level,monthly income,injury position,marital status and other data were surveyed using a general questionnaire.Their NP situation was surveyed using a simplified McGill pain questionnaire (SF-MPQ).Results The patients' average visual analogous scale (VAS) score was 4.37.Their average pain rating index (PRI) according to the SF-MPQ was 8.23,with the PRI-sensory and PRI-emotional components 5.23 and 3.00 respectively.The average degree of present pain intensity was 1.86,between mild pain and discomfort,and discomfort was the description most commonly used.The most common pain descriptor was prickling pain,followed by burning pain and bulge pain.85.7% of the patients felt that their pain had an adverse effect on their affective state,and exhaustion occurred more often than any other descriptive words.Univariant analysis showed that the degree of injury,education level,marital status,monthly income,family support and medication history were all factors correlated with NP perceptions.Multi-variate logistic regression analysis showed that being unmarried and severity of injury were independent protective factors against NP.No family support,no medication and low income were independent risk factors for NP.Conclusion The type of neuropathic pain varies in patients with spinal cord injury.The intensity of the pain is mostly at a medium level.The emotional state of most patients was affected.Neuropathic pain involves many factors.Being unmarried and severely injured are independent protective factors,while lack of family support,no medication,and having low income were independent risk factors.
