Objective To establish a method for the determination of content in Sinomenine Hydrochloride external applied powder. Methods Diamonsil ODS C_(18) (250 mm ? 4.6 mm, 5 ?m) column was used in HPLC with mobile phase of phosphate buffer (0.01 mol/L K_2HPO_4 solution, and 1%0 triethylamine, pH was adjusted to 3.0)-MeOH (80 : 20). The flow rate was 1.0 mL/min and the detection wavelength was 265 rim. Results The linear range of Sinomenine Hydrochloride was 0.446～4.46 ?g and the regression equation was Y=9.01 ? 10~6X+102803 (r=0.9999). The average recovery was 99.2%, RSD=0.68% (n =9). Conclusion This method is rapid and accurate with good reproducibility. It can be applied to control the quality of Sinomenine Hydrochloride external applied powder.

Objective To construct a recombinant lentiviral expression vector containing NIS and EGFP gene,and to explore the feasibility of NIS gene for monitoring the bone marrow derived mesenchymal stem cells (BMSCs) migration to the intracranial glioma.Methods The NIS and EGFP gene fragments were subcloned into lentiviral vector pLVX-puro,then packaged and amplified in HEK293T cells to obtain recombinant lentivirus pLVX-CMV-NIS-EGFP.pLVX-CMV-0-EGFP was constructed as control.BMSCs were isolated,cultured,and transfected by lentivirus.The antibiotic-resistant transfected BMSCs (BMSCs-NIS-EGFP and BMSCs-EGFP) were selected.The expression of NIS gene was examined by Western blot.Functional NIS activity was confirmed by the uptake of 125I and the inhibition effect of NaClO4.The nude mice intracranial glioma models were established.MicroSPECT was performed at 24 h post BMSCs-NIS-EGFP injection via the tail vein.Results pLVX-CMV-NIS-EGFP and pLVX-CMV-0-EGFP were successfully constructed and packaged.BMSCs were successfully isolated and cultured.Stable cell lines BMSCs-NIS-EGFP and BMSCs-EGFP were constructed after lentivirus transfection and puromycin selection.The expression of NIS gene was detected by Western blot in BMSCs-NIS-EGFP,but not in BMSCs-EGFP.BMSCs-NIS-EGFP showed significantly more uptake of 125I (nearly 10 times than the uptake in BMSCs-EGFP) and the uptake could be significantly inhibited by NaClO4.The nude mice intracranial glioma models were successfully established and the BMSCs-NIS-EGFP in glioma foci could be visualized by microSPECT imaging at 24 h post injection.Conclusions A recombinant lentivirus containing NIS gene could be successfully constructed for monitoring BMSCs migration towards intracranial glioma.It might provide evidence on the research of BMSCs and NIS gene mediated therapy for glioma.

Objective To investigate the relation between brain natriuretic peptide (BNP) rs198388 polymorphism and the susceptibility of essential hypertension in Han population of Hunan. Methods A total of 567 patients with hypertension (the hypertension group) and 555 healthy volunteers (the control group) were enrolled. Gender, age, smoking and drinking history of the 2 groups were not significantly different. Blood pressure was measured in the 2 groups. After fasting for 12 h or more, blood glucose, total cholesterol, triglycerides, high density lipoprotein cholesterol and low density lipoprotein cholesterol were measured. DNA polymorphism analysis was done by polymerase chain reaction-restriction fragment length polymorphism method, and genotype was determined by agarose gel electrophoresis. Results The GG, GA, and AA genotypeswere detected.The frequencies of GA and AA genotypes and A allele were significantly lower in the hypertension group (GA and AA:12.3%;A:6.9%) than those in the control group (GA and AA:18.4%; A:9.7%; P=0.009, and P=0.014, respectively). Conclusion BNP rs198388 polymorphism may be associated with essential hypertension in Han people in Hunan. Carrying rs198388 GA and AA genotypes and A allele may be the reason for low risk of hypertension.

Objective One typical case with stress cardiomyopathy was reported and the current knowledge of the syndrome was reviewed to improve relevant knowledge.Methods A 71-year-old female patient presented dyspnea and chest pain due to emotional stress.ECG,echocardiography,selective coronary artery angiography,left ventriculography,~(99)Tc~m-MIBI single photon emission computed tomography (SPECT),~(18)F-FDG SPECT and MRI were performed.Results Electrocardiogram at admission showed ST segment elevation and T wave inversion in leads V1—V4.Pathological Q wave occurred 1 week later,it disappeared 1 month later however and severe T wave inversion occurred.Normal or slightly elevated cardiac enzymes in the blood were found during the course.Left ventriculogram at admission showed left ventricular apical ballooning with LVEF of 30%.The ballooning volume was about 3/4 of left ventricular volume, without any corresponding coronary artery diseases found in coronary angiogram.The abnormal apical ballooning decreased significantly in the follow-up left ventriculogram performed one month later.The LVEF rose up to 63.6%.~(99)Tc~m-MIBI and ~(18)F-FDG SPECT showed mismatch of perfusion and metabolism in the corresponding region,indicating presence of viable myocardium.MRI showed left ventricular apical ballooning without perfusion defect and late enhancement,indicating viability of corresponding myocardium. Conclusions Emotional stress can cause transient left ventricular apical ballooning called"stress cardiomyopathy".Either ~(99)Tc~m-MIBI SPECT associated with ~(18)F-FDG SPECT or delayed enhancement MRI plays an important role in identification of myocardial viability,which can efficiently guide clinical treatment.
