Objective To discuss effect of serum immunoglobulin M (IgM) and superoxide dismutase (SOD) by percutaneous epidural steroid injections in patients with lumbar disc herniation.Methods 137 patients with lumbar disc herniation were selected in Central of Hospital of Wuhan,all patients were randomly assigned joint group and O3 group, all patients were given ozone (O3) injection treatment, before treatment the joint group was given percutaneous epidural steroid injections, the joint group on the basis of O3 injection method was divided into multi-way group and routine group, followed up for 6 months, analyzed all patients therapeutic effect and recurrence rate,used enzyme-linked immunosorbent method to detect patients with serum IgM, SOD level, Pearson analysis method was used to analyze the relationship between the two groups.Results The joint group treatment effective rate was 91.89%, O3 group treatment effective rate was 79.73%, the former was higher than the latter, the difference was statistically significant ( P<0.05), The joint group serum IgM, SOD level was better than O3 group(P<0.05), In six months, multi-way group recurrence rate was 10.81%, routine group recurrence rate was 18.92%,O3 group recurrence rate was 31.08%, multi-way grou P

0.05).Conclusions:Facial nerve excited threshold detection was a simple and effective method of conjecturing TCM syndrome and severity and prognosis of facial paralysis patients.

Objective To investigate the efficacy of radio-frequency disc nucleoplasty and chemonucleolysis with collagenase for the treatment of lumbar disc herniation.Methods Eighty patients with lumbar disc herniation were treated by nucleoplasty combined with chemonucleolysis using collagenase(1200 U) in our hospital from January 2002 to January 2007.Results The patients were re-examined in 2 weeks,4 weeks and 6 months after the operation.According to the modified MacNab criteria,62 patients achieved excellent outcomes,10 were good,6 were fair,and 2 were poor.The rate of excellent and good outcomes were 90%(72/80).No serious complications occurred in this series.Conclusion Radio-frequency disc nucleoplasty and chemonucleolysis with collagenase are minimally invasive and effective for lumbar disc hernia.

Objective To study the Value of low dose CT scanning with gas-contrasted and low window level in diagnosing gastro-colon lesions.Methods 126 cases suspected with gastro-colon lesions were randomly devided into two groups,group A(69 cases) were scanned with conventional water-contrast or non-contrast and conventional expose dose,and with conventional window level,group B(57 cases) were scanned with gas-contrasted and low expose dose,and using low window level.The images were evaluated by 2 experienced radiologists,the results including doctor's self-confidence and diagnostic accurate rate in both group A and group B were compared based on the endoscopic results.Results The diagnostic self-confidence of radiologists and the accurate rate in evaluating the lesions in group B were obviously superior to group A.Conclusion CT scanning of gastro-colon with gas-contrasted,low expose dose and low window level is markedly superior to conventional one.

Objective To establish a gene diagnosis assay for spinal muscular atrophy(SMA) in children. Method Analysis of the survival motor neuron (SMN) gene in 19 SMA patients and in 21 normal controls were performed by using polymerase chain reaction - fragment length polymorphism (PCR - RFLP) method. Result Deletion of exon 7and 8 in SMNt gene were found in all 19 SMA patients, while no such changes were found in normal controls. Conclusion The SMNt gene exon 7 and 8 examine can be applied to SMA gene diagnosis, and the PCR- RFLP method have higher sensitivity and particularity to the SMA diagnosis.

Laboratory of electron microscopy is representative of large instruments laboratories in medical research.And the operation and management in this kind of laboratory are different.Case of forty years of operation and management in the medical laboratory of electron microscopy,this paper analyzed and summarized its successful experiences in the research management system,personnel system and the aspect of equipment maintenance management.Provide a management reference for medical research institutions with the laboratory of similar large-scale instruments.

Objective:To assess the effect of rosiglitazone on inflammation in peritoneal dialysis patients. Methods:Fifty patients undergoing continuous ambulatory peritoneal dialysis were collected in our hospital. The treatment group was assigned to receive regular peritoneal dialysis and rosiglitazone 4mg once daily while the control group was received regular peritoneal dialysis for 12 weeks. Such serum examinations as fasting blood glucose (FBG), glycosylated hemoglobin A1c, haemoglobin, serum total cholesterol, high density lipoprotein cholesterol(HDL-C), low density lipoprotein cholesterol, triglycerides and high sensitivity C reactive protein (hs-CRP) were measured, tumor necrosis factorα(TNF-α) and interleukin-6 (IL-6) levels were measured by ELISA, and homeostasis model as-sessment of insulin resistance( HOMA-IR) was also evaluated before and after the treatment. Results:After the 12-week treatment by rosiglitazone, the levels of FPG, HOMA-IR, hs-CRP, TNF-αand IL-6 were declined significantly(P<0. 05), and the level of HDL-C was increased significantly(P<0. 05). Conclusion: Rosiglitazone shows significant anti-inflammatory, insulin resistance improve-ment and anti-lipidemic effects in peritoneal dialysis patients.

In order to improve the teaching quality of experimental teaching of laboratory diagnosis and to cultivate the clinical ideation of medical students,we have been trying a series of reform in this course and obtained good results.Here,our experience in the selection of teaching contents,the improvement of teaching methods,and the setting of experimental assessment have been summarized and investigated.

Objective To investigate the effect of ANX A1 on the biological characteristics of papillary thyroid carcinom cells by interfering with the expression of Annexina A1 (ANX A1) in papillary thyroid carcinoma cells through small interfering RNAs (siRNA).Methods The designed highly efficient siRNA was used to conduct the specific interfence on ANXA1 expression in the papillary thyroid carcinoma TPC-1 cells.The effect of ANXA1 on TPC-1 apoptosis in PTC was observed by flow cytometry.Results The designed siRAN could efficiently inhibit the expression of ANXA1 mRNA in PTC,enhanced the cell apoptosis in TPC-1 cells in vitro.Conclusion siRNA can interfere with the expression of ANXA1 and promote the apoptosis of papillary thyroid carcinoma which suggesting that ANXA1 may be an important biological target for the treatment of papillary thyroid carcinoma.
