To prepare ginseng saponin Compound K with ultrasound-assisted total zymolytic ginseng saponins. The conversion rate was taken as the index to detect the pre-treatment factors such as ultrasonic power and ultrasonic time, as well as the impact of enzymatic factors, such as pH value, temperature, concentration of substrate, dosage of enzyme and reaction time, on the conversion rate. The response surface method was used to optimize the preparation conditions. The enzymolytic products were identified with MS, 1H-NMR and 13C-NMR. The results showed that the optimum conditions of the ultrasound-assisted enzymolysis were 250 W for ultrasonic power, 15 min for ultrasonic time, 5.5 for enzymolytic pH, 50 degrees C for enzymolytic temperature, 36 h for enzymolytic time, 4:5 for enzymolytic dosage: substrate and 1.0 g x L(-1) for concentration of substrate. The relative molecular mass of reaction products was 622.4. Therefore, the nuclear magnetic map verified that the reaction product was rare ginseng saponin Compound K. Under the above conditions, based on the total zymolytic ginseng saponins, the conversion rate of rare ginseng saponin Compound K was 6.91% in proportion to the total of ginsenosides. The process features gentle reaction conditions, high conversion rate and simple and reliable process, which is suitable for industrial production.

With low molecular weight chitosan and poloxamer 188 as the joint carriers, ginsenoside Rg3 solid dispersions were prepared by using the solvent evaporation method for an in vitro dissolution test. Subsequently, differential scanning calorimetry (DSC), scanning electron microscopy (SEM) and X-ray diffraction (X-RD) were adopted for a phase analysis. The results showed that the 60 min in vitro cumulative dissolution rate of ginsenoside Rg3 solid dispersions prepared with low molecular weight chitosan and poloxamer 188 at the ratio of 2:1 exceeded 90%, and the drug was dispersed in carriers in an amorphous state. Therefore, ginsenoside Rg3 solid dispersions prepared with low molecular weight chitosan and poloxamer 188 could help significantly improve the drug dissolution, with a practical application value.

ObjectiveTo evaluate the clinical effectiveness of posterolateral autograft bone graft fusion transpedicular screw system internal fixation and anterior debridement in the treatment of dorsal and lumber spinal tuberculosis. MethodsFrom March 1996 to July 2000,posterolateral autograft bone graft fusion transpedicular screw system internal fixation and anterior debridement procedures were used in 62 patients suffering from dorsal and lumber spinal tuberculosis in our department,48 of them were involved in a longitudinal study follow-up for a mean of 3.6(1.5-5.5)years postoperatively. ResultsAll patients showed successful posterolateral bone graft fusion. Among 38 cases of Pott's paraplegia, 30 were completely recovered,5 were partly recovered,the rate of recovery was 92.1%. The average immediate postoperative correction of kyphosis angle was 29.1°,the average loss of correction was only 3.2°at final follow-up.ConclusionsPosterolateral autograft bone graft fusion transpedicular screw system internal fixation and anterior debridement procedure were found helpful in strengthening the stability of the spine in dorsal and lumber spinal tuberculosis, providing successful interbody fusion and recovery of Pott's paraplegia, correcting the kyphosis, and preventing progression of kyphosis.

OBJECTIVETo elucidate the regulatory mechanism underlying proliferation and anti-apoptosis in NSCLC by overexpression of miR-21.

METHODSReal-time PCR was used to measure miR-21 abundance in non-small cell lung cancer (NSCLC) tumor samples and adjacent normal tissues, as well as NSCLC cell lines. Tumor suppressor genes as potential targets of miR-21 were predicted by sequence analysis. Luciferase assay and Western blot were used to assess the regulatory effect. The effect on A549 cell viability and apoptosis by miR-21-induced gene repression was tested by trypan-blue exclusion and flow cytometry.

RESULTSmiR-21 expression was 2.24-fold higher in the NSCLC tumor samples and 3.06-fold higher in the A549 cells than that in the adjacent normal tissues. Sequence prediction and gene expression regulation assays showed that miR-21 could reversely regulate the expression of PDCD4 (P < 0.01). Suppression of miR-21 expression is associated with an elevation of Pdcd4, resulting in a significant reduction of proliferation and the apoptosis rate (2.6%) was increased to 10.9%. Moreover, the anti-proliferation and pro-apoptotic effect by miR-21 suppression could be reversed by PDCD4 knock down.

CONCLUSIONSuppression of the tumor suppressor PDCD4 expression may be one of the important regulatory pathways of the miR-21-mediated cell proliferation and decrease of apoptosis in non-small cell lung cancer.

OBJECTIVETo observe the effect of Ginkgo Leaves Tablet (GLT) on memory quotient (MQ) of mild cognitive impairment (MCI) patients.

METHODSOne hundred and thirteen patients were randomly assigned to the control group (55 cases) and the treatment group (58 cases). Patients in the control group received dietetic therapy and physical exercises, while those in the treatment group additionally took GLT, 19.2 mg each time, three times daily. The treatment course was 12 months for all. The MQ of all the patients was assessed by WMS-RC before treatment,at 6-month of treatment, and 12-month of treatment.

RESULTSCompared with the control group, the improvement of MQ increased in the treatment group 0.5 and 1 year after treatment (P < 0.05). The clinical efficiency of MQ obviously increased in the treatment group (48.28% and 50.00%), showing statistical difference when compared with the control group (30.91% and 27.27%, P < 0.05, P < 0.01). There was statistical difference in added scores of recognition, regeneration, understanding, and recitation test at 6-month of treatment and 12-month of treatment between the treatment group and the control group (P < 0.05, P < 0.01).

CONCLUSIONGLT was effective in improving MQ of MCI patients, especially in improving recognition, regeneration, understanding, and recitation test.
