We screened a strain NK13 for a certain extent asymmetric hydrolysis the rac-ketoprofen Chloroethyl ester to (S)-Ketoprofen. As identified, NK13 was Bacillus megaterium. Digested NK13 genomic DNA with Sau3AI partially and recovered the fragment from 2 kb to 6 kb, cleaved the plasmid of pUC18 with BamH I, ligated the 2-6 kb fragment of NK13 genomic DNA into pUC18 plasmid, and then transformed an Escherichia coli strain DH5alpha. We created the gene library of NK13 and obtained a positive clone, pUC-NK1 in the library from the tributyrin flat. The result of sequencing showed that there was a whole open read frame (ORF) of 633 bp lipase gene in the plasmid of pUC-NK1. To compare with the genes of GenBank, this lipase gene was reported firstly (GenBank Accession No. EU381317). The lipase gene was amplified by PCR, using pUC-NK1 plasmid as template, and subcloned into the high expression vector pET21b(+) under the control of T7 promoter. The recombinant plasmid, pET-NKest1, was then transformed into an Escherichia coli strain BL21 (DE3) for the production of recombinant lipase protein. After 3 hours of induction by isopropyl-beta-D-thiogalactoside (IPTG), lipase was expressed. SDS-PAGE analysis showed that the relative molecular mass of the lipase protein was about 20 kDa. The result of high performance liquid chromatography (HPLC) showed that the conversion rate of the recombinant strain was fifty times than the wild strain NK13's. The (S)-Ketoprofen enantiomeric excess of the recombinant strain was 75.28%, which indicated that the lipase could hydrolyze (S)-Ketoprofen Chloroethyl ester firstly. If we research the conditions of the hydrolysis rac-ketoprofen Chloroethyl ester of this lipase further, maybe it could offer a foundation to product (S)-Ketoprofen industrially.

OBJECTIVETo explore new toxicity-reducing methods of Pinellia Rhizoma prepared by ethanol and the latest technical parameters.

METHODPinellia Rhizoma is prepared with ethanol. The orthogonal experimental design was adopted for investigating amount of ethanol, preparing time, ethanol concentration and preparing temperature. The optimal technology was determined by the comprehensive score of toxicological indicators of PGE2 content of rat celiac percolate, with the rabbit conjunctival irritation test as the intuitive validation on toxicology reduction. The pharmacodynamics validation was used to determine the reasonability of the preparation process.

RESULTThe optimal technology was that Pinellia Rhizoma was prepared by 75% ethanol at the temperature of 60 degrees C by 4 days, and then dried. The effect of relieving cough, reducing sputum and anti-inflammatory of Pinellia Rhizoma is not reduced after prepared by ethanol.

CONCLUSIONThe optimal technology of Pinellia Rhizoma prepared by ethanol is simple and reasonable that it can be used as the new method to reduce toxicity and keep efficacy of Pinellia Rhizoma.

Objective To survey the situation of spinal cord injuries (SCI) in Beijing.Methods China Rehabilitation Research Center and Information Center of Beijing Health Bureau sponsored the surveillance of 86 hospitals in Beijing which had hospitalized SCI patients in 2002. The faculty of surveillance was composed of trained professionals. The number of registered SCI patients in 2002 was 1077, and 264 patients in 11 hospitals were chosen to be investigated in detail according to stratified sampling result.Results There were 1077 registered patients with a neurological deficit and the annual SCI incidence was 60 per million. The ratio of male to female was 3:1 and the ratio of cervical, thoracic, lumbar injuries and others is 4.9%, 28%, 66.7%, 0.4% respectively. The mean age at the time of injury was 41 years. The causes most frequently seen were falls from a height and traffic accidents. The mean time of hospitalization was 18.9 days and the mean expenditure of hospitalization was 27819.3 RMB. Four patients were transferred to rehabilitation hospitals, and others went homes directly after discharge.Conclusion There are many reasons for the high annual SCI incidence in Beijing and the first SCI cause was falling from a height, which should be pay special attention when the prevention measures are taken into account. The rate of SCI patients who received systemic medical rehabilitation was low.

Objective:To evaluate the relationship between B-cell lymphoma/adenovirus E1B19 kDa-interacting protein 3-like protein (BNIP3L)/adenovirus E1B-interacting protein and mitochondrial dysfunction in the hippocampus of mice with sepsis-associated encephalopathy (SAE).Methods:One hundred and eighty C57BL/6J mice, aged 6-8 weeks, weighing 20-25 g, were divided into 4 groups ( n=45 each) using a random number table method: control group (C group), sham operation group (Sham group), SAE group, and SAE+ BNIP3L agonist carfilzomib group (SC group). The sepsis model was developed by cecal ligation and puncture (CLP) in anesthetized animals. In SC group, carfilzomib 2 mg/kg was intraperitoneally injected at 2 h after CLP. Twenty mice in each group were selected, and the survival at 7 days after operation was recorded. Eight surviving mice in each group were selected at 1 week after CLP for Morris water maze test. The remaining mice were sacrificed at 24 h after surgery, and the hippocampal tissues were harvested for determination of the expression of BNIP3L (by immunofluorescence) and BNIP3L in mitochondrial protein (by Western blot) and for microscopic examination of the morphological structure of mitochondria. The mitochondrial ATP content was measured by fluorescein-fluorescence enzyme luminescence method, and the mitochondrial membrane potential (MMP) was measured by fluorescence spectrophotometry. Results:Compared with C and Sham groups, the survival rate was significantly decreased, the escape latency was prolonged, the time of staying at the original platform quadrant was shortened, and the number of crossing the original platform region was decreased, the expression of BNIP3L in the hippocampal mitochondria was down-regulated, the MMP and content of mitochondrial ATP were decreased ( P<0.05), the intensity of fluorescence of BNIP3L in the hippocampus was decreased, and the damage to mitochondrial ultrastructure was marked in SAE group. Compared with SAE group, the survival rate was significantly increased, the escape latency was shortened, the time of staying at the original platform quadrant was prolonged, and the number of crossing the original platform region was increased, the expression of BNIP3L in the hippocampal mitochondria was up-regulated, the MMP and content of mitochondrial ATP were increased ( P<0.05), the intensity of fluorescence of BNIP3L in the hippocampus was decreased, and the damage to mitochondrial ultrastructure was attenuated in SC group. Conclusions:BNIP3L-mediated mitochondrial dysfunction may be involved in the mechanism of SAE developed in mice.
