OBJECTIVE:To establish the method for simultaneous determination of 6 components in Lonicera japonica,and to study the content changes of them before and after before and after carbonized. METHODS:UPLC method was adopted. The deter-mination was performed on Agilent Eclipse Plus C18 RRHD column with mobile phase consisting of 0.1% phosphoric acid solu-tion-acetonitrile(gradient elution)at the flow rate of 0.2 mL /min. The detection wavelength was set at 350 nm,and column tem-perature was 25 ℃. The sample size was 1 μL. RESULTS:The linear ranges of chlorogenic acid,rutin,galuteolin,isochlorogenic acid A,isochlorogenic acid B and isochlorogenic acid C were 21.2-424 μg(r=0.9993),1.17-23 μg(r=0.9995),2.18-43 μg(r=0.9998),5.10-102 μg(r=0.9993),2.60-52 μg(r=0.9991),4.95-99 μg(r=0.9998),respectively. RSDs of precision,stability and repeatability tests were all lower than 2.0%. Recoveries were 97.11%-99.76%(RSD=1.20%,n=6),95.20%-99.90%(RSD=2.20%,n=6),95.71%-100.30%(RSD=2.20%,n=6),95.00%-96.98%(RSD=0.88%,n=6),96.47%-103.00%(RSD=2.40%, n=6),95.78%-103.80%(RSD=3.20%,n=6). Compared with before processing,the contents of rutin,isochlorogenic acid B and isochlorogenic acid C in L. japonica were increased along with processing,the contents of chlorogenic acid and isochlorogenic acid A were decreased significantly,while the content of galuteolin had no significant change. CONCLUSIONS:The method is sim-ple,precise,stable and repeatable,and can be used for simultaneous determination of 6 components in L. japonica. Those chemi-cal components have certain changes before and after carbonized.

Objective:To explore the correlation between single nucleotide polymorphisms (SNPs) in Homo sapiens longevity assur-ance homologue 2 (LASS2) gene 3′-untranslated regions (UTR) and susceptibility of bladder cancer among residents of Yunnan, China. Methods:A total of 105 bladder cancer patients (bladder cancer group) and 100 nonbladder cancer patients (control group) were se-lected. PCR method and sequence for LASS2-3′-UTR were performed to identify the SNPs correlated with bladder cancer. The relation-ships between the LASS2-3′-UTR polymorphisms and bladder cancer risk were analyzed. Results:An SNP (rs8444) was identified in LASS2-3′-UTR, and the T/C allele frequencies and genotype distributions of rs8444 largely differed between the bladder cancer and control groups (χ2=10.267, P=0.006;χ2=10.634, P=0.001). Individuals that carry the rs8444 C allele or CC genotype had a remarkably lower risk of bladder cancer compared with those that carry the T allele or TT genotype (OR=0.489, 95%CI:0.309-0.772, P=0.002;OR=0.258, 95%CI:0.081-0.827, P=0.023). No significant correlations were observed between the T/C allele frequencies and genotype distri-butions of rs8444 and TNM stage, as well as histological grade and distant metastasis in bladder cancer (P>0.05). Conclusion: The rs8444 C allele or CC genotype located within LASS2-3′-UTR can lower the susceptibility of bladder cancer among the residents of Yun-nan, China. However, it is not associated with the TNM stage, histological grade, and distant metastasis.
