1.Retrospect and prospect of surgical treatment for gastrointestinal stromal tumor: based on a 10-year experience
Chinese Journal of Digestive Surgery 2013;(4):241-244
Surgical treatment is the treatment of choice for gastrointestinal stromal tumor (GIST).A consensus on the surgical principle of GIST has been made based on the 10-year experience,which effectively guided the standardized treatment of GIST.Laparoscopic and gastrointestinal endoscopic techniques were applied in the treatment of GIST,and promote the development of the diagnosis and treatment of GIST.Laparoscopic treatment has become one of the main treatment methods for GIST.Furthermore,multi-disciplinary treatment for GIST is gradually adopted in clinical practice.In this article,the prospect of surgical treatment of GIST is introduced based on a 10-year experience.

International Journal of Cerebrovascular Diseases 2013;21(5):392-395
arotid artery atherosclerosis is closely associated with ischemic stroke.Carotid artery intimamedia thickness is an important indicator of carotid artery atherosclerosis.Magnesium is involved in the in vivo metabolism of a wide variety of processes.Studies have shown that magnesium can decrease carotid intimamedia thickness.This article reviews the relationship between magnesium levels and carotid artery atherosclerosis in different populations.
3.Determination of Free Thiols in the Chimeric Protein PfCP-2.9 of Plasmodium faldparum
Chinese Journal of Parasitology and Parasitic Diseases 1987;0(02):-
Objective To determine the free thiols in the chimeric protein PfCP-2. 9 of Plasmodium falciparum expressed by Pichia pastoris. Methods Two experiments of reverse phase HPLC and Ellman' s reaction were applied to the PfCP-2.9 for the determination of its free thiols. For RP-HPLC analysis, three kinds of samples were tested: PfCP-2. 9, dithiothreitol-reduced PfCP-2.9 and indoacetic acid-alkylated PfCP-2.9. Results Both experiments showed that there were no any free thiols present in the PfCP-2. 9. Conclution The disulfide bonds between cysteine residues of PfCP-2. 9 were formed completely.

China Pharmacy 2001;0(08):-
OBJECTIVE:To develop an LC-MS method for the determination of the concentration of duloxetine in human plasma.METHODS:Plasma sample(0.2 mL)was taken,with the protein precipitated twice using acetonitrile.The mobile phase consisted of 20 mmol?L-1 ammonium acetate(pH3.5)-methanol-acetonitrile(38∶20∶42).The sample was separated on a Thermo C18 column with plasma concentrations(time-concentration profile)of duloxetine in 10 healthy volunteers determined by LC-MS after taking a single oral dose of duloxetine enteric-capsule(22.4,44.8 or 67.2 mg).RESULTS:The calibration curve of duloxetine was linear over the concentration range of 0.78~100 ng?mL-1(r=0.999 5)with the recovery at 100.8%,the RSD of intra-day and inter-day at no more than 7.8% and 9.3%,respectively.CONCLUSION:The method developed in our study was proved to be accurate and sensitive,and suitable for the pharmacokinetic study of duloxetine.
5.Expression of Plasmodium falciparum MSP1-31 fragment in attenuated Salmonella typhi CVD908 strain induced by tetracycline controlled promoter
Academic Journal of Second Military Medical University 1982;0(01):-
Objective:To express MSP1-31 gene of Plasmodium falciparum in Salmonella typhi CVD908 vaccine strain using a tetracycline-controlled P LtetO promoter. Methods:The MSP1-31 gene was cloned into the plasmid of pZE11 and transformed into the CVD908/tetR strain by electroporation. Expression of MSP1-31 in CVD908/tetR strain was detected using the method of Western blot. Results: The recombinant plasmid of pZE11/MSP1-31 was constructed, there was effective expression of MSP1-31 protein in CVD908/tetR strain in presence of tetracycline, and no expression of gene in absence of tetracycline. Conclusion: The recombinant Salmonella typhi strain in which the expression of Plasmodium falciparum MSP1-31 fragment induced by tetracycline is established successfully.

Objective:To observe the effect of Tangshenning on renal function and LOX-1 mRNA expression in the kidney of early diabetic nephropathy rats model. Methods:Early diabetic nephropathy rats model was made with high fat diet, STZ and unilateral ne-phregtomy. After the 12-week drug intervention, the rats were sacrificed, the kidneys were removed and the mRNA expressions of LOX-1 in the kidney were observed by the method of RT-PCR. Results:Early diabetic nephropathy rats model was successfully made by the triple-modeling method. The mRNA expression of LOX-1 in the kidney was significantly increased, and Tangshenning could low-er the expression of LOX-1 in the kidney in a dose-dependent manner. Conclusion:The abnormal expression of LOX-1 could be one of the mechanisms for diabetic nephropathy. Tangshening has good kidney protective effect through decreasing LOX-1 abnormal expression in the kidneys, which deserves further research.

Objective To evaluate the effect of minocycline on the long-term cognitive function after partial hepatectomy in mice.Methods Sixty-four male C57BL/6 mice,aged 3 months,weighing about 20 g,were randomly divided into 4 groups (n =16 each) using a random number table:control group (group C),partial hepatectomy group (group O),PBS group,and minocycline group (Mino group).At 3 days after partial hepatectomy,the rats underwent Morris water maze test.The animals were sacrificed and their hippocampi were immediately removed for determination of tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) mRNA (using real-time fluorescent quantitative PCR) and nuclear factor kappa B (NF-κB) expression in the nuclcar protein of the cells (using Western blot).After the mice regained consciousness after operation,minocycline 50 mg· kg-1 · d-1 was injected intraperitoneally for 30 consecutive days in Mino group,while the equal volume of PBS was given instead of minocycline in group PBS.The parameters mentioned above were then recorded.Results Compared with group C,the escape latency and swimming distance were significantly prolonged,and the expression of TNF-α mRNA,IL-6 mRNA and NF-κB was up-regulated in group O (P < 0.05).Compared with group PBS,the escape latency and swimming distance were significantly shortened,and the expression of TNF-α mRNA,IL-6 mRNA and NF-κB was down-regulated in group Mino (P < 0.05).Conclusion Minocycline can improve the long-term cognitive function after partial hepatectomy in mice and inhibition of inflammatory responses in hippocampi is involved in the mechanism.
