Objective To observe the influence of the short effect antihypertension drugs- nifedipine and medial effect antihypertension drugs- extended release nifedipine on the blood pressure variability (BPV) in essential hypertension(EH). Methods Twenty-five EH patients were underwent 24-hour noninvasive ambulatory blood pressure monitoring (ABPM) and observed their BPV respectively before taking drugs, after taking nifedipine and extended release nifedipine. Meantime,25 normotensive controls (NC) were observed. Results (1)BPV in EH group was higher than that in controlled group and the severer the rise of blood pressure, the more obvious the increase of BPV (P 0.05). Conclusions Nifedipine could increase BPV but extended release nifedipine did not change BPV while they decreased blood pressure. Effect of extended release nifedipine was better than nifedipine in decreasing blood pressure.

Objective To establish an ultra high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method for detecting α-hydroxybutyrate (α-HB) in serum.Methods Electrospray ionization negative ion and multiple reaction monitoring mode were used to detect serum α-HB.The linearity,low limits of quantification,precision,recovery and interference of UHPLC-MS/MS were evaluated.The reference interval of this method was established in 130 serum samples (62 males and 68 females) from Shanghai East Hospital.Dixon method was used to judge the outliers and K-S test was used to analyze the data normality.The standard curve was scored by linear regression analysis.Results The total run time was 4 min of UHPLC-MS/MS method for the determination of α-HB.It has a good linear relationship in the range of 0.5-40.0 mg/L(r=0.999 4);the low limit of quantification was 0.5 mg/L;the in-batch and inter-batch coefficient of variation precision were less than 4.1％ and 6.3％,respectively;the recovery ranged between 95.8％ and 103.8％.Hemolytic samples (about 5 g/L hemoglobin),lipemic samples (about 12 mmol/L triglyceride),icteric samples (about 150 μmol/L total bilirubin) had no significant interference to the detection.The reference range of the apparent healthy population was 1.46-6.48 mg/L.Conclusions A method for the determination of serum α-HB by UHPLC-MS/MS was established.The method was simple,rapid,and could be used for the detection of clinical samples.

OBJECTIVETo observe the changes of the blood and urine mercury (Hg) levels and liver & kidney functions of rabbits after administration of Jiuyi Dan (calcined gypsum-Sheng Dan 9: 1) for 1 month and the recovery of rabbits after the drug withdrawal.

METHODThe rabbits were randomly divided into 2 groups: the calcined gypsum group and the Jiuyi Dan group. After 36 mg of calcined gypsum and 40 mg of Jiuyi Dan were used on the surface of wound (5 cm x 5 cm) on one side of rabbit back for 4 h, the surfaces of wound were washed by saline. The bloods were taken from the rabbit hearts before and after the drug administration for 14 and 28 days, and after the drug withdrawal for 7, 40, 71, and 92 days for determining Hg level in blood, and liver & kidney function indicators (ALT, AST, CREAT and BUN). The Hg level in urine collected from bladders was examined while rabbits were dissected after the drug withdrawal for 1, 40, 71, and 92 days.

RESULTThe Hg level in blood was significantly increased (P < 0.01) after the rabbits were administrated with drugs for 14 and 28 days and after the drug treatment was stopped for 7 and 40 days. The Hg level in urine was significantly enhanced after the drug withdrawal for 1, 40, 71 days. However, the liver & kidney indicators were not influenced.

CONCLUSIONThe Hg level in rabbit blood and urine was significantly increased after the consecutive administration of double-dose Jiuyi Dan for 1 month. However, the blood Hg level and urine Hg level recover after the drug withdrawal for 71 days and 3 months, respectively. The liver & kidney indicators do not significantly change with the dose.

OBJECTIVETo explore the anti-tumor mechanism of norcantharidin (NCTD) for the implanted tumors of human gallbladder carcinoma in nude mice in vivo.

METHODSAnimal model of implanted tumors of human gallbladder carcinoma in nude mice was established. Mice were randomly divided into control, 5-FU, NCTD and NCTD + 5-FU groups and were taken different treatment. The expressions of PCNA, Ki-67, cyclin D1, p27, Bcl-2, Bax, Survivin, nm23/nm23-H1, MMP2 and TIMP2 proteins or genes in each tissue section of every group were determined by immunohistochemistry and RT-PCR.

RESULTS(1) On proliferation-related gene proteins, the expression of PCNA, Ki-67, cyclin D1 was significantly decreased, with significantly increased expression of p27 protein, in paraffin sections of NCTD group when compared with control group (P < 0.05); The expression of PCNA mRNA, cyclin D1 mRNA was decreased, with significantly increased expression of p27 mRNA in NCTD group. (2) On apoptosis-related gene proteins, the expression of Bcl-2 was significantly decreased in paraffin sections of NCTD group when compared with control group (P < 0.05); The expression of Bcl-2 mRNA, Survivin mRNA was significantly decreased, with significantly increased expression of Bax mRNA in NCTD group. (3) There was significant difference on invasion around tumor and lung metastasis in NCTD group when compared with control group (P < 0.01). On metastasis-related gene proteins, the expression of nm23 and TIMP2 was significantly increased, with significantly decreased expression of MMP2 in paraffin sections of NCTD group when compared with control group (P < 0.05); The expression of nm23-H1 mRNA, TIMP2 mRNA was significantly increased, with significantly decreased expression of MMP2 mRNA in NCTD group.

CONCLUSIONSThe anti-tumor mechanism of NCTD for human gallbladder carcinoma in nude mice might correlated with inhibition of cell proliferation, blockage of cell cycle, induction of cell apoptosis, reducing of cell motility and invasive capability, alteration of the expression of proliferation-, apoptosis- and metastasis-related gene proteins such as PCNA, Ki-67, cyclin D1, p27, Bcl-2, Bax, Survivin, nm23, MMP2 and TIMP2.
