OBJECTIVETo establish an HPLC fingerprint to evaluate the quality of Polygalae Radix, root xylem, and those collected in different growth ages or harvest time.
METHODSeparation was performed at 30 °C on a Kromasil C18 column (4.6 mm x 250 mm, 5 μm); the mobile phases was acetonitrile and 0.05% H3PO4 water in the gradient elution; the flow rate was set at 1.0 mL · min(-1) and the detection wavelength at 314 nm; the quality discriminant analyses were accomplished by means of similarity analysis, cluster analysis, principal component analysis and neural network model.
RESULTIn 26 batches of Polygalae Radix, 24 batches fingerprint similarities were above 0.8. In 5 different growth or harvest time batches, 4 batches were above 0.8; in 8 batches root xylem samples, the similarities were all above 0.875. The similarity analysis was in accord with the quality discriminant analysis of cluster analysis, principal component analysis and neural network model.
CONCLUSIONFingerprint combined with chemical pattern recognition technique can effectively evaluate the quality of Polygalae Radix. The active substance species are all similar in cultivated, wild, different growth or harvest time Polygalae Radix and polygala root xylem, but the chromatography peak areas are different. The effective material contents are similar between wild and cultivated Polygalae Radix, but each chromatographic peak area of the root xylem is much smaller than that of Polygalae Radix. The chemical substance accumulation mainly depends on harvest month, but little growth time in Polygalae Radix.

Objective: To observe the clinical efficacy of deep electroacupuncture (EA) at Baliao points in treating stress urinary incontinence (SUI). Methods: A total of 60 female patients with SUI were divided into two groups according to the order of consultation, with 30 cases in each group. The control group was treated with pelvic floor muscle training. The treatment group was treated with deep EA at Baliao points [Shangliao (BL 31), Ciliao (BL 32), Zhongliao (BL 33) and Xialiao (BL 34)]. Results: The total effective rate was 93.3% in the treatment group, versus 33.3% in the control group, and the total effective rate of the treatment group was significantly higher than that of the control group (P<0.05). After treatment, the scores of international consultation on incontinence questionnaire-short form (ICIQ-SF) and the volume of urinary leakage in both groups were lower than those before treatment (all P<0.05), and the ICIQ-SF score and the volume of urinary leakage in the treatment group were lower than those in the control group (both P<0.05). Conclusion: Deep EA at Baliao points with long needles can improve the clinical symptoms in female patients with SUI, and it has a better curative effect than pelvic floor muscle training.

Haploinsuffieiency of the runt-related transcription factor 2 (Runx2) gene is widely known to be responsible for cleidocranial dysplasia (CCD).To date,more than 190 mutations in Runx2 gene have been reported to be related to CCD.In this study,a novel mutation of Runx2 gene was observed in a female with CCD.Genomic DNA was extracted from peripheral venous blood of the proband and eleven members of her family.Genetic testing on these twelve people identified a novel missense mutation (c.895T>C,Y299H) in exon 5 of the RUNX2 gene in the proband.This mutation results in an amino acid change at codon 895 (P.Tyr 299 His.) from a tryptophan codon (TAT) to a histidine codon (CAT).Our finding may further extend the known mutation spectrum of the RUNX2 gene,and facilitate prenatal genetic diagnosis of CCD in the future.

In order to enhance the antitumor efficacy of recombinant Newcastle disease virus, rNDV-IL15 was rescued in this study. Recombinant plasmid prNDV-IL15 was constructed, and BHK21 cells were transfected with the recombinant plasmid. Finally, the recombinant Newcastle disease virus rNDV-IL15 was successfully rescued. The growth curves of these two recombinant viruses were determined. Murine melanoma B16F10 cells were infected with rNDV-IL15 at MOI of 0.1, and the expression level of IL15 in the supernatant was detected by ELISA. The antitumor efficacy of rNDV-IL15 and rNDV was compared in vitro and in vivo. Results showed that prNDV-IL15 was constructed and recombinant virus rNDV-IL15 was successfully rescued. The growth curve of rNDV-IL15 showed that the growth of rNDV-IL15 had not been changed after insertion of IL15 gene. Results showed that there was high level of IL15 expression in the supernatant of rNDV-IL5-infected B16F10 cells (1 044.3 +/- 27.7 ng x mL(-1)). rNDV-IL15 and rNDV significantly inhibited the growth of B16F10 cells in vitro in a time-dependent manner. However, there was no significant difference between them. In animal experiments, rNDV-IL15 efficiently suppressed tumor growth in vivo when compared with rNDV, and the difference was statistically significant. The results suggested that rNDV-IL15 is a more effective antitumor agent.

OBJECTIVETo investigate the feasibility of genetic diagnosis of Down's syndrome (DS) using short tandem repeat (STR), and to develop a rapid and accurate method for diagnosing DS.
METHODSQuantitative fluorescence polymerase chain reaction (QF-PCR) was used to amplify STR loci D21S11, D21S1440 and Penta D of 719 samples. Three hundred and eighty-nine samples were peripheral blood, 282 were amniotic fluid, 48 were chorionic villous samples. The products were analyzed using eleterophoresis to detect DS.
RESULTSAmong 652 samples with a normal karyotype, 635 showed 2 bands with a 1:1 ratio or a single band. The remaining 17 samples showed 3 bands, and were regarded as false positive results. For 67 DS samples, 53 showed 3 bands/peaks with a 1:1:1 ratio and 14 showed 2 bands/peaks with a 2:1 ratio. The sensitivity and specificity of STR loci D21S11, D21S1440 and Penta D were 76.12% and 98.62%, 71.64% and 98.93%, 89.55% and 99.85%, respectively. The overall sensitivity and specificity of 3 STR loci were 100% (67/67) and 97.39% (635/652), respectively.
CONCLUSIONCompared with conventional method, author's method is simpler, more stable and rapid, and can be used for large-scale prenatal screening of DS.

OBJECTIVETo study the effect of Zilongjin (ZLJ, a composite Chinese drug) on proliferation and apoptosis of human breast carcinoma cell line MCF-7.
METHODSMCF-7 cells were randomly divided into four groups depending on the culture solution used, the control group, cultured with 1640 medium not contained ZLJ; and the three ZJL groups cultured with medium contained low (1.5 mg/mL), moderate (3 mg/mL) and high (6 mg/mL) dosage of ZLJ crude drug respectively. The changes of cell proliferation were assessed by cell growth curve assay and methyl thiazolyl tetrazolium (MTT) assay. And the cell apoptosis was analyzed by flow cytometry, Hoechst 33342 staining and DNA ladder assay.
RESULTSCompared with that in the normal control, the counts of cells in the three ZLJ groups were decreased significantly (P<0.05) at such time point as 24, 48, 72, 96, 120, and 144 h. Furthermore, apart from the comparison of the growth inhibition rate between the low and moderate dosage group at 24 and 72 h which were found to be no significant difference (P>0.05), the comparison f that among the three ZLJ groups appeared to be significant difference (P<0.05). The inhibitory effect of ZLJ on cell proliferation of MCF-7 was time- and dose-dependent; it could retard cells in G0/G1 cell phase; apoptosis of MCF-7 cell was induced by moderate and high dosage of ZLJ with revealing of apoptotic body and DNA ladder formation.
CONCLUSIONZLJ shows cell proliferation inhibitory and apoptosis inducing effects on human breast cancer cell line MCF-7, and thus to realize its anti-tumor action.

OBJECTIVETo investigate the effect of ginsenoside-Rg3 on lung metastasis of ribonuclease inhibitor (RI) gene-transfected mouse B16 melanoma.
METHODSC57BL/6 mice were iv injected with parental or RI-transfected B16 melanoma cells. Lung metastasis was assessed by the number of surface tumor nodules. Mice were divided into 6 groups. Group I, II and III of mice were given parental, mock-transfected and RI-transfected B16 melanoma cells, respectively while in group IV, V and VI, Rg3 (1.5 mg/kg, iv q.o.d. x 10) was given to mice bearing parental, mock-transfected and RI-transfected B16 melanoma, respectively. Micovessel density (MVD) of the lung metastatic tumor was assessed by immunohistochemical staining of factor VIII-R expression.
RESULTSThe number of tumor nodules was significantly decreased in mice injected with RI-transfected B16 melanoma (Gp III, compared to Gp I and II). Rg3 treatment per se could also decrease the number of lung tumor nodules but to a lesser extent (Gp IV and V compared to Gp III). However, Rg3 synergized with RI transfection resulting in most significant inhibition of lung metastasis (Gp VI). Mice in Gp I and II died within 26 days of the experiment, whereas all the mice in Gp VI were alive during the observation period of one and one half month. MVD was significantly decreased in the lung tumor nodules in mice injected with RI-transfected B16 melanoma. It was further decreased when additional Rg3 was given (Gp VI).
CONCLUSIONTransfection of ribonuclease inhibitor gene significantly reduces the metastatic potential of B16 melanoma. Ginsenoside-Rg3 has a synergistic effect.
