Objective To observe the therapeutic effect of single lower limb traction plus massage for the lumbosacral tunnel syndrome.Methods The selected 80 candidate patients were divided into the observation group with 38 patients and treatment group with 39 patients. The observation group received single lower limb traction plus massage and the treatment group received pelvic traction plus massage. Both groups therapy last 5 days, The Japanese orthopaedic association scores (JOA) was evaluated for subjective symptoms, signs, functional activity and bladder function score. The therapeutic effect was evaluated.Results The total effective rate (94.7% vs. 82.1%;χ2=12.160,P=0.007) in the observation group was significantly higher than that in the control group. O, The scores of JOA at one week after treatment (20.2 ± 2.0 vs. 18.3 ± 2.8;t=3.419, P<0.01) and two weeks after treatment (24.4 ± 1. 4vs. 22.6 ± 3.0;t=3.359,P<0.01) in the observation group were significantly higher than those in the control group.Conclusions The single lower limb traction plus massage can improve the clinical symptoms of patients with lumbosacral tunnel syndrome, and be superior to the pelvic traction plus massage.

OBJECTIVETo assess the feasibility of a polymer material-expanded polytetrafluoroethylene (ePTFE) as wound covering.

METHODSForty-five Sprague Dawley (SD) rats inflicted with open wound on the back were divided into 3 groups, each group 15 rats. Wounds in the autograft group were covered with autologous skin. Wounds in the allograft group were covered with skin from 15 Wistar rats (donor). Wounds in the experiment group were covered with ePTFE. Wound healing in each group was observed with naked eye. Tissue specimens collected on 3rd, 7th, and 14th post-operative day (POD) respectively were stained with HE and examined under light microscope. Macrophages, lymphocytes and fibroblasts were quantified. IL-2 and IFN-gamma levels in the infiltrating mononuclear cells were assessed by immunohistochemistry with expression of gray value.

RESULTSWounds in rats of autograft group and experiment group healed well without redness, swelling or infection. Rejection was evident in the allograft group rats on 8th POD, including epidermis degeneration and focal necrosis in different degree, plus red swelling on wound edge. The numbers of macrophages, fibroblasts, lymphocytes in allograft group were significantly higher than those in autograft group and experiment group (P < 0.01). The average gray values of IL-2 and IFN-gamma of allograft group on 7th POD were 129 +/- 7 and 113.7 +/- 2.7, which were significantly lower than those in the experiment group (144 +/- 8, 137.3 +/- 1.9, respectively, P < 0.01) and allograft group (189 +/- 6, 180.3 +/- 3.7, respectively, P < 0.01).

CONCLUSIONSePTFE will induce minimal inflammatory response and foreign body reaction. It is unlikely to cause side effect when applied to wound surface for a prolonged period. Thus, it is suitable to use ePTFE as wound surface covering.

Intersectin is an evolutionarily conserved multifunctional adaptor protein with multifunctional domains. These domains interact with components of the endocytic and exocytic pathways, such as the clathrin mediating synaptic vesicle recycling, the protein related to endocytosis via caveolae, the with-no-lysine kinases related to the regulation of renal outer medullar potassium, and the Cdc42 mediating exocytic pathway. Recently, the understanding of intersectin function in the pathogenesis of endocrine tumor and many neurodegenerative diseases such as Down syndrome, Alzheimer disease has been deepened. This article reviewed the structure and roles in endocytosis/exocytosis and diseases of intersectin.

Objective To detect the characteristics of benign infantile seizures.Methods Fifty seven cases of benign infantile seizures were analyzed.Results All patients had a normal development before and after the onset of the seizures.The age of onset was from 1.5-30 months.The main manifestations included tonic clonic seizure,staring and motion arrest,64.9 % occurred in clusters.A family history of epilepsy or febrile seizures was present in 6 cases.Interictel electroen cephalograms were normal.The seizures were easily ceased after taking phenobarbital,carbamazepine or valproate.Antiepileptic drugs(AEDs)were discontinued in 51 patients.The mean ages of seizure stopping were 12.8 months and mean seizure′s durations were 4.1 months.Conclusion The benign infantile seizures can be easily controlled with a single AEDs for short time with favorable prognosis.

Objective To evaluate the value of ultrasound (US) in assessment knee joint inflammation in patients with juvenile rheumatoid arthritis(JRA).Methods US scans of the knees obtained in 30 children at clinically active stage; JRA was compared with those obtained in 30 healthy children and 10 JRA patients in clinical remission.Results Changes in synovial membrane thickness and presence of fluid in suprapatellar bursa showed statistically significant differences between JRA patients with active disease and the other subjects.Alterations in contour of the articular cartilage were demonstrated in 10 knees of patients with JRA.Conclusion US is a simple sensitive and reliable methods for the assessment and monitoring of knee joint involvement in JRA.

Objective To study the relationship between sleeping disorder and anxiety of nursing undergraduate students.Methods Pittsburgh sleep quality index (PSQI) and Hamilton Anxiety Scale (HAMA) were adopted to investigate 120 nursing undergraduate students randomly chosen from Nursing School of Jilin University to discuss the relationship between sleeping disorder and anxiety.Results An analysis of correlation and regression indicated that : PSQI and the total average scores of scores of HAMA were in a notably positive correlation, also anxiety could lead to sleeping disorder.Conclusions The nursing undergraduate students should pay more attention to their own sleep quality, reduce or eliminate the anxiety syndrome, thereby becoming a nurse with a sound mental and physical health.

OBJECTIVETo study the autophagy activity between rat bone marrow stem cells (BMSCs) neural differentiation in order to explore the mechanism involve in this process.

METHODSBMSCs were passed by 3 generation, then was induced with the revulsant 2% (DMSO) + 200 µmol/L (BHA), NSE expression was detected by immunocytochemical stain, the mRNA expression of autophagy associated genes L3B, Beclinl, Atg5, Atg7, Atg10 were detected by RT-PCR, the autophagy protein LC3B was examined by Western blot and flow cytometry analysis.

RESULTSBMSCs were passed by 3 generation, the purity of BMSCs could reach more than 90%, the morphology of cells were like fibroblasts, after the revulsant 2% DMSO + 200 µmol/L BRA induced, cells were extended long neurites, like nerve cells, positive rate of NSE staining was (83±5) %, RT-PCR results showed that the expression of autophagy associated genes LC3B, Beclinl, Atg5, Atg7 Atg0 were rised after BMSCs neural differentiation, Western blot analysis showed that the LC3B-II protein expression was increased after neural differentiation and the MFI of L3B was highten by flow cytometry.

CONCLUSIONAutophagy is increased after rat BMSC neural differentiation.

OBJECTIVETo explore a new method to correct secondary lip whistle deformities and nasal base depression after bilateral complete cleft lip (BCCL) repair with lip subdermal soft tissue flap.

METHODSBilateral subdermal soft tissue "C" flaps and "lambda" flap were designed to repair secondary deformities of nasal base and reconstruct vermilion tubercle in patients after BCCL repair.

RESULTSGood results were achieved in all the patients with primary healing. No flap necrosis happened. The result was satisfactory.

CONCLUSIONSWith bilateral subdermal soft tissue "C" flaps and " lambda" flap, nasal base depression deformities and lip whistle deformities can be corrected. It is an ideal method for correction of deformities after BCCL repair.
