Objective To investigate the efficacy of microendoscopic tubular retractor system (METRx) in the management of lumbar intervertebral disc herniation. Methods By using the METRx system with modified instruments, the lumbar discectomy was performed in 550 cases. During the operation, patients were placed in a knee-chest sitting position, and the instrumentation was utilized into the vertebral canal through the ligamenta flava. Results The patients were followed for 6~36 months (mean, 21 months). According to the Nakai criteria, the curative outcomes were “excellent” in 478 cases (86.9%), “good” in 60 cases (10.9%),“fair” in 6 cases (1.1%), and “poor” in 6 cases (1.1%). The 6 cases with “poor” results obtained “fair” results after a re-operation of lateral recess enlargement and residual nucleus removal under microendoscope. Conclusions Lumbar discectomy with the utilization of the METRx system is minimally invasive, safe and effective.

Objective:To investigate the effect of estrogen on the expression and distribution of IL-1 in the remodeling osteoporotic alveolar bone.Methods:Ovariectomy was performed on 30 female SD rats and sham operation on 15(control group).When osteoporosis was developed in the 30 ovary-removed rats,the left maxillary molars of all the rats were extracted.On the following day 15 of them were treated with intramuscular estrogen injection at 20 ?g/kg once every 3 days(treatment group).Another 15 rats with ovary removed received no treatment(osteoporosis group).7,30 and 60 days after teeth extraction 5 rats were killed respectively in each group.IL-1 expression in alveolar bone was examined immunohistochemically,and semiquantitative analysis of cellular-staining intensity was done by microphotometry.Results:The positive IL-1 expression were mainly located in the osteoclasts,vascular endothelial cells and fibroblasts.7 days after teeth extraction the cellular-staining intensity of IL-1 in control group,osteoporosis group and treatment group was 0.11?0.019,0.36?0.038 and 0.18?0.025 respectively(control or treatment group vs osteoporosis group,P

BACKGROUND: We have previously reported that marine algae polysaccharide derivant can significantly promote bone cell growth.OBJECTIVE: To observe the effect of marin algae polysaccharide derivant in treatment of osteoporosis.METHODS: Sixty female Wistar rats were randomly divided into control group, treatment group and model group. There were 20 rats in each group. The rats in treatment group and model group were respectively treated with retinoic acid to induce osteoporosis. The rats in treatment group were gavaged the marine algae polysaccharide derivant 10 mg/kg, and the rats in model group were gavaged the glucose 10 mg/kg orally for 14 days. Changes of rat femur bone histological examination and histomorphometry parameters were observed.RESULTS AND CONCLUSION: The mean Trabecular Number (Tb.N), the mean Trabecular Thickness (Tb.Th) and the percent Trabecular Area (Tb.Ar%) were significantly decreased in the model group compared with control group. The mean trabecular separation (Tb.Sp) was greatly increased. After intake of marine algae polysaccharide derivant, Tb.N, Tb.Th and Tb.Ar% of the treatment group were significantly more than that of the model group. The Tb.Sp was obviously reduced. These indicate that marine algae polysaccharide derivant can increase bone mass and have a therapeutic and preventional effect on the osteoporosis.

Objective To observe on the variance of serum IL-18 level and lymphocyte subpopulations in the patients with obese diabetic(T2DM).Methods The diabetic obese group contained 31 cases,the non-diabetic obese group contained 33 cases,healthy normal body weight group contained 23 cases,the blood glucose(FPG),insulin (FPI),blood total cholesterol(TC),triglyceride(TG),IL-18 and the cell population of lymphocyte subpopulations CD3+and CD4+、CD8+ in peripheral blood were determined,the insulin sensitivity index were calcnlated.Results Compared with the healthy normal body weight group,the blood fat,FPG,FPI,IL-18 of T2DM patients significantly increased,there were significant statistical difference(P < 0.05 or P < 0.01).The ISI significantly decreased(P < 0.01).Compared with the non-diabetic obese group,the blood fat and IL-18 of T2DM patients significantly increased (P<0.05).Compared with the diabetic obese group,the subpopulations cell population of CD3+、CD4+、CD8+ in the non-diabetic obese group significantly decreased,the ratio of CD4+/CD8+ significantly increased,there were significant statistical difference(P<0.05 or P<0.01)in the two groups comparison.Compared with the non-diabetic obese CD4+/CD8+ significantly increased(P<0.05).Conclusion T2DM patients should prevent the hyperinsulinemia,control blood sugar,reduce insulin resistance,sustain normal lipid metabolism,boost immune function.

AIM: To study the protetive effects of Danshenhonghua Injection (Radix Salviae Miltiorrhizae,Stigma Croci,etc) on acute cerebral ischemia in rats. METHODS : The model of acute incomplete cerebral ischemia was built by ligaturing bilateral carotid arteries. Cerebral index,cerebral water content ,capillary permeability of brain,and the change of cerebral morphology in rats were observed. RESULTS : The cerebral index,cerebral water content,capillary permeability of brain decreased remarkably with 7.2,14.4mg?kg -1 of Danshenhonghua Injection,and the injury of brain tissue was also abated by Danshenhonghua Injection significantly. CONCLUSION : Danshenhonghua Injection has the protetive effects on acute cerebral ischemia.

OBJECTIVE:To provide reference for drug use labeling for pregnant and lactating women. METHODS:The drug package inserts were collected from Linxi Hospital of Kailuan General Hospital during Jul. 2013-Dec. 2015. The information about drug use labeling for pregnant and lactating women was analyzed statistically. RESULTS:Among 762 drug package inserts,pack-age inserts which were not labeled with or labeled with indefinite drug use information for pregnant and lactating women accounted for 31.89% and 52.76% respectively. Among package inserts of 361 domestic chemical drugs and biological products,339 Chinese patent medicine and 62 imported drug,package inserts which were not labeled or labeled with indefinite drug use information for pregnant and lactating women accounted for 22.99% and 25.21%,44.54% and 88.50%,14.52% and 17.74%,respectively. CON-CLUSIONS:Except for poor drug use labeling for pregnant and lactating women in package inserts package,there still are other problems,such as items listed dispersedly,presentation content not consistent. Compared with imported drugs,the missing informa-tion for pregnant and lactating women are obvious in drug package inserts of domestic chemical drugs and biological products,and severe in those of Chinese patent medicine. It is recommended that drug manufacturers should strengthen drug tracing and monitor-ing after listed,and update and revise related content of package inserts timely;drug administration department should strengthen drug package inserts supervision,and unify and standardize labeled content management of drug use.

Objective To provide reference for developing and perfecting the open resources of national-wide cancer genomics-related data by collecting, systematizing, organizing, sharing and applying the related data of the National Genome Atlas ( TCGA) Program. Methods The technical process, sharing and use of TCGA Program data were in-vestigated. Results TCGA established the whole linkage data management process by cooperating with multiple cen-ters, including tissue sample collection, processing, quality control, sequencing, characteristics analysis, data sharing and application of research achievements. The data were classified according to the related cancer, data types and their processing. The mutation, amplification and deficit of related cancer characteristic genes and the af-fected signaling pathways were studied according to the two sharing mechanisms underlying open access and con-trolled access to the collected data and individual data. Conclusion Studies on TCGA Program can provide experi-ences and reference in data management for the implementation of large scale TCGA Program.
