This study was aimed to establish a separation method for neochlorogenic acid reference substances from Lonicera japonica. Refined neochlorogenic acid inL. japonica water extract was separated and concentrated by HPD200A macroporous resin, which was isolated and purified by medium-low-pressure preparative chromatography and determined by HPLC. The structure was identified by various spectroscopic data including ESI-MS,1H-NMR and13C-NMR. The results showed that the optimal purification technology conditions were as follows: washed with 5BV of water, collected elution, concentration, drying; neochlorogenic acid crude products were eluted with acetonitrile-0.5% formic acid solution (10:90) with the flow rate of 20 mL·min-1; and the detection wavelength was 326 nm. The contents of the prepared neochlorogenic acid reached to 98.86% and the yield was 89.1%. It was concluded that the method was effective for the preparation of neochlorogenic acid with high purity. It can be used to prepare the reference substances for quantitative analysis and content determination of Chinese materia medica.

Objective To prepare a gene chip for detecting polymorphisms on coding region of genes in hepatocellular carcinoma tissuses. Methods Genes harboring in loss regions with high frequency of hepatocellular carcinoma (HCC) were selected, the related information was inquired and the cSNP sequences were obtained in the SNP database of National Center for Biotechnology Information(NCBI).Then the appropriate primers and oligonucleotide probes were designed according to the SNP sites and the gene chip for the detection of SNPs were constructed. This chip includes 48 cSNPs of 25 hepatocellular carcinoma-related genes. The PCR products labeled by Dig-dUTP were hybridized with cSNP chip. Results The sensitivity, influence of probes and reiteration of the chip were detected. The results indicated that the chip was sensitive about 6?10~(-3) ng/?l. The signal of hybridization was down with lower concentrition of probes. By the chip, 7 of polymorphisms of caspase9 ( rs2308941) C→T and DOK2(rs2242241)T→G, 6 of polymorphisms of EGFL3(rs947345)A →G,caspase9 ( rs2308938)C→G and PHGDH(rs1801955)T→A, 5 of polymorphisms of E2F2(rs3218170) G→A,4 of polymorphisms of MUTYH(rs1140507)T→C and BNIP3L(rs1055806)G→T, 1 of polymorphism of TNFRSF1B (rs1061622)T→G were detected in the tissues of 10 HCC. Samples of caspase9 ( rs2308941G) and ( rs2308941A) were verified by PCR-SSCP and sequencing. Conclusion We prepare the cSNP chip of hepatocellular carcinoma-related genes, which can accelerate the discovery of polymorphic markers on hepatocellular carcinoma.

OBJECTIVE: To explore the clinical effects and short-term complications of using free jejunum graft (FJG) to reconstruct the defects by resections of pharyngeal, laryngeal or cervical esophageal cancers. METHOD: Fifty-eight cases of pharyngeal, laryngeal or cervical esophageal cancers were reconstructed with FJG. All cases were analyzed retrospectively. RESULT: The success rate of FJG transplantations was 91.4% (53/58). The incidence of post-operative short-term complication was 43.1% (25/58), which was not related to age or BMI. The most common complication was anastomotic leakage (18.9%), which was not related to per-operative radiation therapy. However, BMI > 25 cases had significantly higher incidence of anastomotic leakage than BMI ≤ 25 cases (P = 0.009). The second and third most common complications were respiratory system complications (10. 3%) and FJG necrosis (8. 6%). Para-operative death rate was 3.4% (2/58). Two-year overall survival rates of hypopharyngeal cancer and cervical esophageal cancer were 49% and 67% respectively. The group with no short-term complications had a slightly better survival rate than the group with short-term complications from the Kaplan-Meier curve, but there was no significant difference (P = 0.103). CONCLUSION FJG is ideal to reconstruct cervical digestive tract circumferential defects with a high success rate and a low mortality. However, the post-operative complication rate is high. Intensive observation, early detection and timely treatment of complications are crucial.

Objective To observe the effects of culture medium of a mn iotic cells on NO and NOS in retinal tissues of rabbits in vitro in order to pro vide a protective method for antioxidation in retina transplantation. M ethods Thirty adult healthy rabbits (30 right eyes) were divided into 3 groups. Group Ⅰ: fresh retinal tissue; group Ⅱ: routine culture medium; group Ⅲ: culture medium of amniotic cells. The retinal tissues in group Ⅱ and Ⅲ we re cultured in the corresponding culture medium for 1 week. The content of NO an d NOS in retinal tissues in the 3 groups were determined. Results Compared with group I, the content of NO and NOS of group Ⅱ increased obvio usly (t=3.821, 3.854; P0.05) . Conclusion Culture medium of amniotic cells may remove free r adicals and enhance the ability of antioxidation.

AIMTo investigate the effects of soy isoflavones (SI) on the expression of Bax mRNA and Ca(2+) -ATPase activity in ovaries of perimenopause rats.

METHODSThe animal model of perimenopause rats was established by unforced aging. 12 month-old presenilins female Wistar rats were administered by intragastric (ig) with low (500 mg/kg), middle (158 mg/kg) and high (500 mg/kg) does of SI for 8 weeks. The expression of Bax mRNA in ovaries were detected by RT-PCR. Ca(2+) -ATPase activity in ovaries and MDA content and SOD activity in serum were detected by chemi-chromatometry.

RESULTSIntervention of SI could significantly decrease the expression of Bax mRNA in ovaries and MDA content in serum, increase Ca(2+) -ATPase activity in ovaries and SOD activity in serum of presenilins rats (P < 0.05 or P < 0.01).

CONCLUSIONSoy isoflavones could down-regulate the expression of Bax mRNA and increase Ca(2+) -ATPase activity in aged ovaries. It is probably one of the mechanisms to improve the function of aged ovaries in perimenopause rats.
