Objective To compare the clinical effects of extracorporeal shock wave treatment (ESWT) on lumbar ramus posterior nervorum spinalium syndrome and to compare the effectiveness of applying it in X-ray orientation with pain-point orientation.MethodsSixty patients with lumbar ramus posterior nervorum spinalium syndrome were randomly divided into an X-ray orientation group and a pain-point orientation group with 30 subjects in each group.The two groups then received ESWT with the X-ray orientation and pain-point orientation,respectively.The ESWT was delivered at the energy of 0.12 to 0.20 mJ/cm2 and the frequency of 60-80 pulses per minutes.A total of 1000-1500 shock wave pulses were delivered every time.Three sessions of ESWT were administered,with a 3-5 days of interval between each session.The results were rated using the 75 scores of the lumbar function quantification index recommended by Greenough.Ratings were done before treatment,and after the first,the second and the third treatment.ResultsThere was no significant difference between the groups' average index scores before treatment.There were however significant differences from the baseline scores after the first,the second and the third treatments.There was no significant difference in average lumbar function quantification scores between the groups after the first treatment,but the inter-group differences were statistically significant after the second and the third treatments.After three treatments the cure rate in the X-ray orientation group was 76.7％ and overall effectiveness was 93.3％.Both were significantly higher than in the pain-point orientation group (33.3％ and 76.7％ respectively).ConclusionsThe advantages of X-ray orientation when administering ESWT for lumbar rami posterior nervorum spinalium syndrome are more exact positioning and more effective treatment.The effect was obviously better than with pain-point orientation.

To generate recombinant adenovirus expression vector of human Sema4C gene and observe its expression in mouse myoblasts cell line C2C12 for ensuring easy access to investigate the role of Sema4C gene during myogenesis. The recombinant plasmid was packaged and amplified after being transfected in HEK293 cells through Lipofectamine. After infecting C2C12 myoblasts with recombinant adenovirus vector, the adenoviral infection efficiency was determined by confocal microscope which showed that the expression of green fluorescence could be detected at 12h and then reached peak at 24h after recombinant adenovirus infection. The infection efficiency was almost 100% confirmed by FACS examination. Detection of WB indicated that the expression of Sema4C in C2C12 of recombinant adenoviral infection group was significantly higher than that of the control group (P

OBJECTIVE: To estimate the application of prognosis evaluation of ulnar nerve injury by 1H-magnetic resonance spectroscopy (1H-MRS). METHODS: The metabolites of first dorsal interossei (FDI) of two hands from 12 healthy volunteers and 1 volunteer with complete ulnar nerve injury were detected by 1H-MRS and the data were statistically analyzed. RESULTS: For the FDI of healthy adults, the female peaks area of extra-myocellular lipids (EMCL) was higher than the male (P < 0.05); There was no significant difference in Cho, Cr and intra-myocellular lipids (IMCL) between male and female (P > 0.05); There was no significant difference in all the peaks area between the left and right hand (P > 0.05). The EMCL peak of the injury side was higher than that of the healthy side, and the area of FDI was reduced in the volunteer with ulnar nerve injury. CONCLUSION Noninvasive and quantitative detection of 1H-MRS may be valuable for prognosis evaluation of peripheral nerve injury.

Objective To construct a recombinant expressing plasmid of the hy1 gene of Enterococcus faecium and to express the recombinant Hy1 protein in E.coil.To explore the immune response in mice fed orally with Hyl protein.Methods hy1 gene was amplified by polymerase chain reaction(PCR)and inserted into a prokaryotic expression vector pQE-30.The recomhinant plasmids were transfected into DH5_?to express Hy1 fusion proteins,which were purified by Ni~--column. Western blot was employed to confirm the immunogenicity of the purified protein.Mice were immu- nized by feeding with the fusion protein.The concentrations of antigen-specific antibody in the serum, mucosal fluid and faces were detected by enzyme-linked immunosorbent assay(ELISA).The role of these antibodies in the anti-infection response was evaluated after the mice were challenged with TX0016.Results hy1 gene was sequenced as 1662 bp,the fusion protein encoding polypeptides of 553 amino acid residues.The relative molecular weight was 60 000 when it was determined by sodium dodecylsulfatepo-lyacry-lamide gel electropboresis(SDS-PAGE).The dissolvable expression protein accounted for 38% of total cell protein.After processed by affinity chromatography,the purity of fusion protein was above 92%.Western blot analysis confirmed that fusion protein could be specifically recognized by the anti-TX0016 serum.The concentrations of serum IgA,serum IgG,faeces sIgA and intestmucosal fluid sIgA was 0.365?0.048,0.431?0.064,0.743?0.056 and 1.112?0.113 respectively in hy1 groups and 0.051?0.013,0.098?0.019,0.102?0.032 and 0.187?0.051 respectively in control group.The differences were statistically significant.The mice survival rate after TX0016 challenge was 70% in hyl group and 50% in control group.There was significant difference between these two groups.Conclusion The results indicate that oral immunization with hyl can induce effective mueosal immune response and produce high level sIgA.

Objective To discuss the short-term clinical effect including functional change of lipiodol- arsenic trioxide emulsion on the primary hepatic carcinoma.Methods Fifty-two patients undergone arterial chemoemblization were selected and then randomly divided into two groups:treatment group(n=27)and control group(n=25).Patients in treatment group were treated with lipiodol-arsenic trioxide,while those in control group treated with mitomycin,epirubicin,cisplatin or lipiodol.Clinical symptoms and six liver function parameters were observed and analized.Results The clinical symptoms of patients in treatment group improved much better than those in control group,and the liver function impairment of patients in treatment group also decreased more than those in control group.Conclusions Lipiodol-arsenic trioxide is an effective and safe intervention-therapeutic embolization material for primary hepatic carcinoma.

Objective To explore the effect of early comprehensive rehabilitation therapy on dysphagia after stroke. Methods A total of 120 stroke patients with dysphagia were collected from December 2006 to May 2009 and divided into 3 trial groups and a control group randomly.No treatment was given to patients in the control group.Patients in trial group 1(T1)were given rehabilitation training,while patients in trial groups 2(T2)and 3(T3)were treated with VitalStim and electrical acupuncture,respectively,in addition to the rehabilitation training.A standardized swallowing assessment (SSA) and the swallowing quality of life(SWAL-QOL) scale were used to evalu-ate all the patients before and after 4 weeks of treatment. ResuIts No statistically significant difference was re-vealed before the treatment among the groups in terms of the patients'sex,age,course of disease,SSA or SWAL-QOL results.Statistically significant improvement was observed after treatment in the 3 trial group,but not in the control group with regard to the SSA and SWAL-QOL scores compared with those before treatment.The trial groups all had higher scores than the control group after treatment.while T2 and T3 had higher scores than T1 after treatment.There was no statistically significant difference between groups T2 and T3.Conclusions Early compre-hensive rehabilitation therapy can improve swallowing and the quality of life of stroke patients with dysphagia.Reha-bilitation combined with neuromuscular electrical stimulation provides effects similar to that of training combined with electrical accupuneture,and is more effective than simple training in treating dysphagia.

Objective To investigate the clinical significance of the 3D-CTA (three-dimensional computed tomography angiography)assisted design of finger reconstruction the second toe.Methods Between June 2010 and January 2013,five patients with finger defect received 3D-CTA assisted finger reconstruction surgeries using the second toe.Preoperative ipsilateral foot and hand 3D-CTAs were conducted and the 3D digital models were analyzed.The accurate positions and adjacent relations of vessels in both donor and recipient site were precisely marked and then the calibers of the vessels were measured.Four cases received thumb reconstructions and 1 case received little finger reconstruction.All of these surgeries were second-stage.According to Gu Yudong's classification of finger defect:second degree 2 cases,third degree 2 cases,five degree 1 case(little finger).Results With the help of 3D-CTA,five patients in this group had no vascular crisis,and all fingers survived successfully.With 4-12 months' follow-up,the algesthesia and thalposis of the reconstructed fingers gained good recoveries.The two-point discrimination was 5-10 mm.Tthe range of flexion of interphalangeal joint was 10 °-30 °.The range of flexion of the metacarpophalangeal joints was 35 °-80 °.And all patients restored walking and bearing functions with 3 months after surgeries.Conclusion The 3D-CTA reconstruction based digital model of ipsilateral foot and hand can objectively reflect the real situation of the vessels in both donor sites and recipient sites (exist of variations,routes and the calibers of the vessels),thus improve the success rate of surgery.

OBJECTIVE: To explore the effects of Salvia miltiorrhiza on renal morphology and renal function of rats with streptozotocin diabetes. METHODS: Thirty male Wistar rats were randomly divided into three groups, which were normal control group, untreated group and Salvia miltiorrhiza-treated group. Diabetic nephropathy was induced in rats of the last two groups by intraperitoneal injection of streptozotocin after unilateral nephrectomy. Then the rats in the normal control and untreated groups were fed with normal saline while those in the Salvia miltiorrhiza-treated group were fed Salvia miltiorrhiza preparation for 8 weeks. The glomerular volume (VG), kidney-to-body weight ratio (KW/BW), urinary albumin excretion rate (UAER) and creatinine clearance (Ccr) were observed. The expression levels of transforming growth factor-beta1 (TGF-beta1), connective tissue growth factor (CTGF), fibronectin (FN) and plasminogen activator inhibitor-1 (PAI-1) were detected by real-time quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) at the end of the experiment. RESULTS: UAER, Ccr, VG and KW/BW ratio were significantly higher in the untreated group than those in the normal control group (P<0.05). The expression levels of TGF-beta1, CTGF, PAI-1 and FN in the untreated group were also significantly higher as compared with those in the normal control group (P<0.05). UAER, Ccr, VG, KW/BW ratio and the levels of TGF-beta1, CTGF, PAI-1 and FN in the Salvia miltiorrhiza-treated group were obviously lower than those in the untreated group (P<0.05). CONCLUSION: Salvia miltiorrhiza can protect rats with streptozotocin diabetes from diabetic nephropathy by suppressing the over-expressions of TGF-beta1, CTGF, PAI-1 and FN in renal cortex.
