Objective To evaluate the curative effect and indications of medical ozone for the treatment of lumbar disc herniation.Methods 10~20 ml(35~45 ug/ml) medical ozone was injected into the lumbar disc percutaneously each case. The patients were followed up for 6~12 months. Results 60 cases (66 lumbar discs) with lumbar disc herniation were treated with the injection of medical ozone. The total effective rate was 96.67% , excellent and good rate was 76%.The efficacy in herniation to be 30% of vertebral canal diameter and lumbardisc bulging group. Conclusion The treatment of lumbar disc herniation with medical ozone is simple,effective and no complications.

Objective To study hematotoxic effect of formaldehyde in mice.Methods Sixty healthy KM mice were randomly divided into a control group and three formaldehyde treated groups named a low level group,a moderate level group and high level group.Themice in the experimental groups were exposed to formaldehyde by intraperitoneal injection,once a day,for three weeks at the dose of 0.2,2.0 and 20 mg/kg bw respectively.Five mice were sacrificed at the 1st,2nd,3rd week of formaldehyde treatment and the blood samples were collected.The red blood cell counts,white blood cell counts and the hemoglobin content in the blood in mice were determined.Results During the experimental period,the body weight of mice in low level group at the 1st and 3rd week decreased significantly compared with the control group.The organ coefficient of the kidney in the moderate level group,high level group at the 1st week were higher than that of control group.The organ coefficient of the spleen in moderate level group at the 2nd week,in all three formaldehyde treated groups at the 3rd week was lower than that of control group.The organ coefficient of the heart in high level group at the 3rd week also decreased markedly in comparison to that of control group.The hemoglobin content in high level group at the 3rd week was lower than that of the control group.The red blood cell counts in three experiment groups at the 1st week and in high level group at the 2nd week decreased markedly compared with the control group.The white blood cell counts were seen much lower in low level group at the first two weeks,in moderate level group at the 1st week and in high level group in the experimental period compared with the control group.Conclusion Formaldehyde exposure has some hematotoxic effects in mice.

The relationship between probiotics and host intestinal immune system was reviewed. Then, as a new immunomodulator, the mechanisms and clinical uses of probiotics were discussed.

A case of Schwannoma in the submandibular gland was reported which had been misdiagnosed as pleomorphic adenoma before operation. The tumor was originated from lingual nerve which in turn invaded the Schwann membrane near the submandibular ganglion.

BACKGROUND:Poly-D,L-lactic-co-glycolic acid (PLGA) that was characterized as absorbable,weak cytotoxicity,and adjustable hardness was ideal to be synthetized artificial spinal dura mater.Because of lacking of functional group at the surface of PLGA,it should be modified to fit the demand of satisfied biocompatibility.OBJECTIVE:To study the biocompatibility of PLGA membrane modified by type-Ⅰ collagen and chitosan.DESIGN,TIME AND SETTING:Contrast observation study,which was carded out in the Biochemistry and Molecular Biology Laboratory Shanghai University of Traditional Chinese Medicine from May to December 2007.MATERIALS:Porous PLGA membrane was provided by Jinan Banzheng Biology-Technology Co.,Ltd.,type-Ⅰ collagen by Sigma Company,USA,chitosan by Shanghai Qisheng Biological Agent Medical Apparatus and Instrument Company,and L929 L cell by Cellular Institute of Shanghai Academy of Life Science,Chinese Academy of Science.METHODS:PLGA membrane (P membrane),PLGA/type-Ⅰ collagen composite membrane (PG membrane),PLGA/type-Ⅰ collagen/chitosan (9:1) composite membrane (PGC 9:1 membrane) and PLGA/type-Ⅰ collagen/chitosan (5:5) composite membrane (PGC 5:5 membrane) were produced through a certain process.MAIN OUTCOME MEASURES:Contact angle,absorption rate and cytotoxicity were tested.Morphological changes of L929 L cell cultured for 1,3,and 7 days were observed under fiberscope.RESULTS:Contact angle was shown as PG membrane＜PGC 9:1 membrane＜PGC 5:5 membrane＜P membrane (P＜0.01 );absorption rate was shown as P membrane＜PGC 5:5 membrane＜PGC 9:1 membrane＜PG membrane (P＜0.01).L929 L cell was characterized as well distribution,expansion and appearance after inoculation of PG membrane,PGC 9:1 membrane and PGC 5:5 membrane.Cytotoxic experiment (MTT methods) showed that,on the 1st day,there was no significant difference in absorbency among groups (P＞0.05).On the 3rd and 7th days,there were significant differences between P membrane and PG membrane or PGC 9:1 membrane,and between PGC 9:1 membrane and PCK2 5:5 membrane (P＜0.05).PGC 9:1 membrane could further improve cell adhesion and proliferation,and PGC 5:5 membrane could inhibit cell proliferation and differentiation.CONCLUSION:Type-Ⅰ collagen and chitosan appended to the exterior of PLGA can enhance the biocompatibility of membrane.In terms of biocompatibility,PLGA/type-Ⅰ collagen/chitosan (9:1) composite membrane can be fit to the qualification as a type of material of artificial spinal dura mater.

Innate lymphoid cell is a type of newly discovered innate immune cell , which can function as adaptive T cells . Based on the transcription factors and the expression of effector cytokines , innate lymphoid cells can be categorized into three sub-groups:ILC1, ILC2 and ILC3.The inflammatory factors these produced by ILC play an important role in the development of inflamma -tory bowel disease (IBD), but ILC3 can secrete IL-22, which promotes the restoration of intestinal epithelial cells .Exploring the func-tion of ILC has a great significance in the treatments of IBD .This article reviews their phenotype , function and also relationship with IBD.

Objective To evaluate the clinical diagnosis,treatment and prognostic factors of kidney clear cell renal carcinoma(KIRC)in international sample database.Methods From 1998 to 2012,consecutive patients with KIRC who diagnosed and treated in TCGA organizations were enrolled.Clinical characteristics,objective response and survival time were evaluated,and correlation analysis with lncRNA urothelial cancer associated 1 (UCA1)gene was performed.Results 512 patients with KIRC were enrolled.35.4% of patients were female,59.6% of stage Ⅰ -Ⅱ, 90.0% of white and 45.1% of grade 1 -2.Comprehensive treatment was consistent with the clinical guidelines. Significant correlation was found between UCA1 expression and 4 mRNA subtype,30 genes mRNA expression, mir -101 -1 expression and PBRM1 mutation.And patients with UCA1 overexpression could achieve poor prognosis. Conclusion Diagnosis and treatment of the international TCGA -KIRC research meets clinical guidelines.UCA1 overexpression is an important poor prognostic factor.Combined with the clinical relevance of other important driver genes,UCA1 may be significantly valuable for further study.

AIM: To investigate the processing and HPLC fingerprint of Radix Scutellariae processed with wine,and to set up appropriate quanlity control standard. METHODS: chromatographic condition of HPLC-UV fingerprint consisted of Hypersil C_18 column(200 mm?5.0 mm,5 ?m),mixture of methanol,0.4% phosphoric acid and acetonitrile as a mobile phase in a gradient mode.Flow rate was 1.0 mL/min and detection wavelength was set at 277 nm. RESULTS: There were no evident differences among fingerprints of Radix Scutellariae that was normatively processed from the production areas. CONCLUSION: The process is feasible,and can be used to provide a basis for quanlity control of Radix Scutellariae.
