Objective To observe the clinical efficacy of acupuncture at Jiaji (EX-B 2) points plus pelvic floor muscle exercises in treating postpartum stress urinary incontinence.Method A total of 216 patients with stress urinary incontinence were randomly divided into a treatment group and a control group, 108 cases each. The treatment group was intervened by acupuncture at Jiaji (EX-B 2) points plus pelvic floor muscle exercises, while the control group was intervened by pelvic flor muscle exercises alone. For the two groups, the treatment was given once a day, 12 sessions as a course. The total effective rates were compared after 2 treatment courses.Result The total effective rate was 90.7% in the treatment group versus 83.3% in the control group, and the difference was statistically significant (P<0.05).Conclusion Acupuncture at Jiaji (EX-B 2) points plus pelvic floor muscle exercises is an effective method in treating postpartum stress urinary incontinence, and can promote the postpartum recovery of the pelvic floor.

Background and purpose:There were reports that radiotherapy might intensify angiogenesis and result in the resistance of tumor to radiotherapy.Endostar,a new type rh-endostatin,may specifically inhibit angiogenesis and tumor growth,so it may reduce the resistance to radiotherapy.This study was to evaluate the inhibitory effect of Endostar in combination with radiation compared with cisplatin(DDP) plus radiation on lung adenocarcinoma A549 in BALB/c nude mice.Methods:We established A549 lung adenocarcinoma xenograft models.When the largest diameter of tumor reached 1.0 cm,all mice were randomized into 4 groups(n=6):control,radiation alone,radiation plus DDP,radiation plus Endostar.We measured the largest diameter and the vertical diameter of the tumors at different time points after treatment.At the 16th day,mice were executed and the tumors were subjected to removal for the analysis of apoptosis,and the expression level of basic fibroblast growth factor(bFGF) mRNA by reverse transcription-polymerase chain reaction(RT-PCR) and vascular endothelial growth factor(VEGF) were also detected by immunohistochemistry.Results:The tumor growth velocity of control,radiation alone,radiation plus DDP,radiation plus Endostar were(162?6)%,(131?8)%,(104?7)% and(108?11)% respectively(P0.05).The apoptosis rates of control,radiation alone,radiation plus DDP,radiation plus Endostar were(12.2?1.1)%,(16.5?0.8)%,(24.4?1.5)% and(20.5?1.9)%,respectively(P

Objective To report a newly designed method of cervical subtotal corpectomy with the posterior vertebral wall retention. Methods 89 cases of cervical spondylotic myelopathy(CSM) or cervical injury were treated with subtotal corpectomy with the posterior vertebral wall retention from March 2001 to March 2004. 61 males and 28 females, aged from 25 to 76 years(mean, 47 years) were included, which involved 62 cases of multiple level in CSM with or without radiculopathy, 14 fractures of cervical vertebral body with or without cervical dislocation, 13 cervical instability with or without cervical disc disease. Subtotal corpectomy with 2 mm retention in posterior wall of the vertebral body were performed, in which 23 cases' level were C4,55 C5 and 11 C6. Extensive decompression through intervertebral body space was performed and bone fusion with autogenous iliac bone graft or titanium mesh supplemented with anterior locking plates were used, the bone graft or mesh were impacted into the decompression slot between the upper to lower endplate as well as the preserved lateral and posterior wall stably. Bone fusion were assessed with roentgenogram during the 3rd, 6th, 12th month follow-up and neurological function was recorded. Results The average operation time is 100 min, ranged from 55-130 min, the blood loss were 120 ml, ranged from 30 to 300 ml. Neither plate or screw migration, nor bone graft loosening or subsidence were found in 77 patients with over 6 months follow-up. Bone fusion happened in all patients, and Frankel score improved 1.0 level averagely after operation. 3 patients with hoarseness recovered 2 weeks later. Conclusion Subtotal corpectomy with posterior wall of vertebrae retention was a feasible anterior decompression procedure with advantage of safety, completely decompression and reliable bone fusion. This method included double level of CSM, and cervical fracture as well as two level of local ossification of posterior longitudinal ligament.

[Objective]To compare the immediate therapeutic effects of the treatment of gluteal muscle constracture(GMC)with arthroscopic release of contractured tissue and conventional surgery.To investigate the indications of arthroscopic surgery.[Method]Ninty-six limbs of 48 patients with traditional surgery and 84 limbs of 42 patients with arthroscopic surgery were analyzed in terms of operation time,length of the incision,postoperative pain,complications,the time of exercise,postoperative hospital stay and one-year recurrence rate.[Result]Arthroscopic surgery group had smaller incisions,earlier exercise,less postoperative pain and shorter hospital stay than conventional surgery group,but the two groups showed no significant difference in operative time,complications,effects of operation and one-year recurrence rate.[Conclusion]Arthroscopic release of contracture tissue is a safe,effective,economical and cosmetic way to treat the gluteal muscle contracture.This method is worthy of wide promotion.

Objective:To investigate the priorities of each factor influencing the casualties in refugees living in border areas, so as to provide evidence for casualty forecasting in the refugees. Methods: We summarized the factors affecting the refugee casualty in the border area through searching and reviewing the related literatures. The identified factors were classified into 3 levels and the quantitative index system was established by using Delphi method, i.e. expert consulting method. The names and the meanings of each index were revised according to experts’ suggestions after 3 rounds of consulting. The weights of each index were determined by analytic hierarchy process (AHP) and comparing-reordering method. Results: A 3-level quantitative system was successfully constructed, which consisted of 4 first level indices (including natural factors, social factors, medical factors, and war factors), 12 second level indices, and 37 third level indices; the weights of all indices were determined. Conclusion: The result of our study can be used in predicting refugee casualty and provide a reference for the medical service of refugees living in the border areas.

Objective To investigate the effect of high glucose on the number and proliferation, migration and adhesion of peripheral endothelial progenitor cells (EPCs). Methods Total mononuclear cells (MNCs) were isolated from peripheral blood by Ficoll density gradient centrifugation, and then the cells were plated on fibronectin coated culture dishes. After 7 days of culture, several groups of attached cells were incubated with glucose in a series of concentrations (15, 25, 35, 45mmol/L) for different durations (6, 12, 24 and 48h). EPCs were characterized as adherent cells which were double positive for DiLDL uptake and lectin binding by direct fluorescent staining demonstrated under a laser scanning confocal microscope. EPCs were further documented by demonstrating the expression of KDR, VEGFR 2 and AC133 with flow cytometry. EPCs proliferation, migration and in vitro vasculogenesis activity were assayed with MTT assay, modified Boyden chamber assay and in vitro vasculogenesis kit, respectively. EPCs adhesion assay was performed by replating MNCs on fibronectin coated dishes, and then the adherent cells were counted. Results Incubation of isolated human MNCs with high glucose concentration decreased the number of EPCs, and this effect was most prominant when glucose concentration was 45mmol/L, and incubated for 24 hours (approximately 1 fold decrease, P
