Thrombolytic therapy is a safe and effective way to cure thrombosis. Developing the safe,effective and cheap therapeutic thromolytic agents are important to prevent and cure thrombosis. In recent years,several fibrinolytic enzymes have been found in the resources of Asian traditional fermented foods,such as Japanese natto,Korea Chungkook-Jang,Chinese Douchi and fermented shrimp paste. These fibrinolytic enzymes secreted by food-grade microorganisms are safe and effective,and are potent thrombolytic agents. The physical and biochemical properties,thrombolytic characteristics,and the potential applications of these fibrinolytic enzymes from Asian fermented food,are reviewed.

To know the characteristics of Shuxuening injection used on cerebral infarction patients in clinical practice, 6 053 cases of Hospital information system (HIS) data from 20 hospitals were analyzed. Using the basic description method and association rules to analysis the data. By analysis the data we found that the average age of cerebral infarction patients who used Shuxuening injection is 67.96, 83.94% of patients were aged 46-80. The injection is administered intravenously,with most patients receiving a dosage of 15-20 mL per dose for between 1 and 14 days. It is always combined with aspirin (48.508%), cinepazide maleate injection (22.073%), atorvastatin calcium tablets (18.873%) in clinical practice. When it comes to two drug combinations, it always combined with cinepazide maleate injection and aspirin (8.178%), nicergoline capsules and aspirin (7.63%). Therefore, based on existing data, we give the conclusion that for the treatment of cerebral infarction Shuxuening injection is mainly used for older patients, and is often combination with similar pharmacological effects chemical drugs, which is complied with the guidelines. However, the wrong dose is still exist, doctors should realize the hiding risk.

An HPLC method to determine six alkaloids of the Coptidis for Chinese Pharmacopoeia of 2015 Edition was established through C18 column. The mobile phase was CH3CN-0.25 mol·L-1 NH4Ac (36:64) (containing 8 mmol·L-1 SDS and adjusting pH 9.3 with ammonia) at the flow rate of 1 mL·min-1, the detective wavelength was 270 nm and the column temperature was 35 oC. The linear ranges of jatrorrhizine hydrochloride, columbamine hydrochloride, epiberberine hydrochloride, coptisine hydrochloride, palmatine hydrochloride and berberine hydrochloride were 0.006 96-0.233, 0.004 75-0.152, 0.003 30-0.528, 0.006 31-1.010, 0.004 71-0.753, 0.017 8-2.884 μg·mL-1, respectively. The average recoveries were 99.65%, 98.59%, 98.49%, 98.66%, 98.64%, 98.63% and RSD were 0.03%、0.15%、0.21%、0.12%、0.28%、0.23%, respectively. The method is simple and accurate, and can be used to determine the contents of jatrorrhizine, columbamine, epiberberine, coptisine, palmatine and berberine in the Coptidis.

Objective To study exogenous expression and subcellular localization of wild type (WT ) and mu-tant PAX3 proteins in vitro by generating their expression plasmids for further study of pathogenesis of Waarden-burg syndrome (WS) .Methods The plasmids pECE-PAX3 and pcDNA3 .0-HA were ligased after they were cut by double enzyme digestion using molecular cloning technique to generate recombinant eukaryotic expression plasmid pcDNA3 .0-PAX3-HA ,which was as a template to generate expression plasmids pcDNA 3 .0 -H80D -HA and pcDNA3 .0-H186fs-HA of novel mutations H80D and H186fs of PAX3 gene .All constructs were verified by di-rect nucleotide sequencing .NIH3T3 cells were transfected transiently with the expression plasmids of PAX3 ,H80D and H186fs respectively .The exogenous expression of WT PAX3 protein and mutant H80D ,H186fs proteins were analysed using Western blot assay ,while their subcellular distribution were observed using immunofluorescence as-say .Results The DNA sequences of expression plasmids of PAX3 and its mutant H80D ,H186fs were correct . Both WT and mutant PAX3 proteins were detected at the expected size .WT PAX3 and H80D proteins were only lo-calized in the nucleus ,whereas H186fs protein showed aberrant localization in both cytoplasm and nucleus .Conclu-sion We successfully generated the recombinant eukaryotic expression plasmids of PAX 3 gene and its mutants and drew preliminary conlusion of gene mutation having effect on subcellular distribution of WT PAX 3 proteins in vitro , which lays experimental basis for further study of the moceluar mechanism of WS caused by PAX3 gene mutations in China .

A research combined trickling filter system and active sludge aeration system was applied in the treatment of industrial wastewater from gas-generating with heavy oil. The wastewater contained both high contents of NH+4-N and mixed hydrocarbons including various PAHs. Its BOD5/COD ratio was less than 0.3 and belongs to recalcitrant, toxic wastewater. The results showed a touch-growth biofilms system was formed on the porous packing material and it played a key role in the decrease of toxicity of the influent. It could also improve the biodegradability of the wastewater.

Objective To analyze the epidemiological characteristics of Mycobacterium tuberculosis by enterbaeterial repetitive intergenic consensus-polymerase chain reaction(ERIC-PCR)DNA fingerprint. Methods Mycobacterium tuberculosis positive sputum samples between September 2003 to May 2006 were collected and cultured.Chromosomal DNA were extracted and ERIC-PCR DNA fingerprinting was analyzed by software,such as RAPD PHYLIP and Treeview.Results A total of 42 different fingerprints were detected.Phylogenetic analysis showed that they could be classified into three clusters,the clustering rate was 72.6%.The characteristics of ERIC-PCR fingerprint patterns were related to age,drug resistance,and type of resistance.Conclusions ERIC-PCR DNA fingerprinting technique used in this study is good for epidemiological studies with its strong discrimination,simplicity and rapidness.A high level of recent transmission is found in our city.

Objective To investigate the effect of arsenic exposure on learning and memory ability of rats.Methods Fourty- eight weaned SD rats were randomly divided into four groups,12 in each.The control group drank tap water,the other three groups treated with sodium arsenite at doses of 2.72 mg/L,13.6 mg/L and 68 mg/L for 12 weeks.Morris water maze was used to test the spatial learning and memory ability of rats.Arsenic level in the blood and brain was assessed after Morris water maze test.Results Arsenic contents in the blood of arsenic exposed rats were significantly higher than that in control rats(P

Objective To discuss the frequent etiology of spontaneous sub-cortical hemorrhage and its diag- nosis.Methods The clinical materials of 79 cases of spontaneous sub-cortical hemorrhage were analyzed.Results 56% of the hemorrhage was caused by arterial-venous malformation.48% of the hemorrhage was caused by occult AVM.Conclusion AVM is the most frequent etiology of spontaneous sub-cortical hemorrhage.CTA plays a special role in its diagnosis.
