OBJECTIVE:To investigate the clinical efficacy of tobradex in treating delayed anterior uveitis following intraocular lens implantation for patients with cataract.METHODS:19 cases(19 eyes,observation group)were treated with tobradex gutta and tobradex eye ointment,while 11(11 eyes)in control group were treated initially with dexamethasone by iv gtt,followed by prednisone taken at a draught with dosage decreased gradually after 3～5 days plus tropicamide eye drops for mydriasis.RESULTS:After treatment for 3 to 5 days,all patients achieved rapid improvement in inflammation and a favorable turn in visual acuity.No adverse reactions were noted in the observation group during treatment;however,the side effects such as irritation,insomnia,abnormal elevation in blood pressure and serum glucose level were noted in a few cases in the control group.CONCLUSION:Tobradex is effective for treating delayed anterior uveitis after cataract surgery.

Objective To explore oligodendrocyte selective vulnerability in gray matter area and the effect of subhypothermia after transient forebrain ischemia in gerbils.Methods The gerbils model of forebrain ischemia was induced by 15 min bilateral carotid occlusion.All gerbils were divided randomly into sham operation group,ischemic reperfusion group and subhypothermia treatment group (32.5?0.5℃).Immunohistochemistry for cell specific antigens (transferrin,TF) was used to identify oligodendrocyte.Results The density of TF positive oligodendrocyte in the cortex at 1～2 days reperfusion following ischemia decreased remarkably (P

Objective To explore the relationship between reactive astrogliosis and delayed neuronal ischemic tolerance by preconditioning ischemia in gerbil hippocampal CA 1 region.Methods All gerbils were divided randomly into sham operation group,cerebral ischemia group and preconditioning ischemia group and preconditioning ischemia plus subsequent ischemia group. Transient forebrain ischemia model was induced by bilateral carotid occlution in gerbils. Immunohistochemistry for cell specific markers (glial fibrillary acidic protein(GFAP)was used to identify astrocyte.Results The numbers of GFAP positive astrocyte in hippocampal CA 1 region increased slightly at 1~7days following preconditioning ischemia, but increased significantly at 28 days after preconditioning ischemia ( P

OBJECTIVE:Bone morphogenetic protein (BMP) plays a vital role in the prevention and treatment of skeleton diseases, recently researches on the molecular mechanism of sheep prolific FecB gene indicated that BMP and its receptors have important influence on animal follicular development. In this study the influence of different type BMPs andits receptors on the follicular development was reviewed in order to explore effective modulation on animal reproduction.DATA SOURCES: Computer was applied to retrieve Medline database on the related literatures from January 1998 to June 2005. The retrieval words were "BMP" and "BMPR" that combined respectively. Language in the articles was limited to English. Simultaneously related articles were also computer searched in China periodical full text database and Wanfang databases from January 1996 to December 2005 with the retrieval words of "BMP, BMPR", that limiting the article language to Chinese.STUDY SELECTION: At first, the document was retrieved, altogether 200 studies on BMP and its receptors were enrolled including 140 Chinese literatures and 60 English literatures.DATA EXTRACTION: these literatures were screened and 30 were included for relating to the BMP characteristic, as well as the influence of BMP and its receptors on follicular development and reproductive endocrine.DATA SYNTHESIS: Of the 30 literatures, 18 experiments discussed the function of BMP and its receptors and its signal transduction mechanism,12 were about the influence of different BMP on reproductive cell secretion, as well as receptor mutation on ovulation.CONCLUSION: BMPs family plays vital role in animal reproductive modulation, current experiments prove that the changes of signal transduction due to BMP receptor gene mutation has made breakthrough for the exploration of the prolific mechanism in sheep. Moreover studies on follicular development modulation and ovulation mechanism are liable to provide theoretical reference for the prolific modulation in sheep or other species.

BACKGROUNDEndostar™ (rh-endostatin, YH-16) is a new recombinant human endostatin developed by Medgenn Bioengineering Co. Ltd., Yantai, Shandong, P.R.China. Pre-clinical study indicated that YH-16 could inhibit tumor endothelial cell proliferation, angiogenesis and tumor growth. Phase I and phase II studies revealed that YH-16 was effective as single agent with good tolerance in clinical use.The current study was to compare the response rate , median ti me to progression (TTP) ,clinical benefit andsafety in patients with advanced non-small cell lung cancer ( NSCLC) , who were treated with YH-16 plus vi-norelbine and cisplatin (NP) or placebo plus NP.

METHODSFour hundred and ninety-three histologically or cy-tologically confirmed stage IIIB and IV NSCLC patients , withlife expectancy > 3 months and ECOG perform-ance status 0-2 , were enrolledin a randomized ,double-blind ,placebo-controlled , multicenter trial ,either trialgroup : NP plus YH-16 (vinorelbine 25 mg/m² on day 1 and day 5 ,cisplatin 30mg/m² on days 2 to 4 , YH-167.5mg/m² on days 1 to 14) or control group : NP plus placebo (vinorelbine 25 mg/m² on day 1 and day 5 ,cis-platin 30 mg/m² on days 2 to 4 ,0.9% sodium-chloride 3 .75 ml on days 1 to 14) every 3 weeks for 2-6 cycles .The trial endpoints included response rate ,clinical benefit rate ,time to progression,quality of life and safety .

RESULTSOf 486 assessable patients , overall response rate was 35.4% in trial group and 19.5% in controlgroup (P=0 .0003) . The median TTP was 6 .3 months and 3 .6 months for trial group and control group respectively (P < 0 .001) . The clinical benefit rate was 73 .3 %in trial group and 64.0% in control group (P=0 .035) .In untreated patients of trial group and control group ,the response rate was 40 .0% and 23.9%(P=0 .003) ,the clinical benefit rate was 76 .5 % and 65 .0 % (P=0 .023) ,the median TTP was 6 .6 and 3 .7months (P=0 .0000) ,respectively .In pretreated patients of trial group and control group ,the response ratewas 23.9% and 8.5%(P=0 .034) ,the clinical benefit rate was 65.2% and 61.7%(P=0 .68) ,the median TTP was 5 .7 and 3 .2 months (P=0 .0002) ,respectively . The relief rate of clinical symptoms in trial groupwas higher than that of those in control group ,but no significance existed (P > 0 .05) . The score of quality oflife in trial group was significantly higher than that in control group (P=0 .0155) after treatment . There were no significant differences in incidence of hematologic and non-hematologic toxicity , moderate and severe sideeffects betweentrial group and control group .

CONCLUSIONSThe addition of YH-16 to NP regimen results in significantly and clinically meaningful improvement in response rate , median time to tumor progression,and clinical benefit rate compared with NP alone in advanced NSCLC patients . YH-16 in combination with chemotherapy shows a synergic activity and a favorable toxic profile in advanced cancer patients .

For wild natural medicine, unanticipated biodiversity as species or varieties with similar morphological characteristics and sympatric distribution may co-exist in a single batch of medical materials, which affects the efficacy and safety of clinical medication. DNA barcoding as an effective species identification tool is limited by its low sample throughput nature. In this study, combining DNA mini-barcode, DNA metabarcoding and species delimitation method, a novel biological sources consistency evaluation strategy was proposed, and high level of interspecific and intraspecific variations were observed and validated among 5376 Amynthas samples from 19 sampling points regarded as "Guang Dilong" and 25 batches of proprietary Chinese medicines. Besides Amynthas aspergillum as the authentic source, 8 other Molecular Operational Taxonomic Units (MOTUs) were elucidated. Significantly, even the subgroups within A. aspergillum revealed here differ significantly on chemical compositions and biological activity. Fortunately, this biodiversity could be controlled when the collection was limited to designated areas, as proved by 2796 "decoction pieces" samples. This batch biological identification method should be introduced as a novel concept regarding natural medicine quality control, and to offer guidelines for in-situ conservation and breeding bases construction of wild natural medicine.
