OBJECTIVETo evaluate the correlation between the results of photoplethysmography and modified Allen test in healthy volunteers of different ages.

METHODSIn 240 healthy volunteers of 3 different age groups, namely the young group (below 40 years of age, n=98), middle-aged group (between 40 and 60 years, n=74) and senior group (above 60 years, n=68), photoplethysmography and modified Allen test were performed to evaluate the recovery time of the hand circulation after relief of ulnar artery compression, and the correlation between the results of the two tests was analyzed.

RESULTSThe results of photoplethysmography and modified Allen test showed a positive linear correlation (P<0.01). The recovery time of hand circulation in the senior group was significantly longer than that in the young group and middle-aged group (P<0.01). In each group, the recovery time of the blood flow as defined by modified Allen test was significantly shorter than that determined by modified Allen test.

CONCLUSIONThe results of photoplethysmography and modified Allen test show a good positive linear correlation in determining the recovery time of hand blood flow in healthy volunteers of different ages after relief of the ulnar artery compression, but the results of latter test can be more objective.

Dioscin has a wide range of biological effects and broad application prospects. However the studies concerning the toxicology and mechanism of dioscin is small. This article is to study the hepatotoxicity of dioscin and the effect of dioscin treatment on expression of aryl hydrocarbon receptor (AhR) mRNA and CYP1A mRNA and protein in HepG2 cells in vitro. Dioscin 0.5-32 µmol · L(-1) exposed to HepG2 cells for 12 h, cell viability was examined by CCK-8 assay and the release rate of lactate dehydrogenase (LDH) was to evaluate cell membrane damage. HepG2 cells morphologic changes were quantified by inverted Microscope, and the effect on production of reactive oxygen species (ROS) was detected by flow cytometry. The mRNA expression of CYP1A and AhR was evaluated by RT-RCR. The protein expression of CYP1A1 was detected by western blot. The cell viability was significantly inhibited after HepG2 cells were exposed to dioscin 0.5-32 µmol · L(-1). Compared with the control, the LDH release rate and ROS were significantly increased. The expression of CYPlA and AhR mRNA was increased. The expression of CYP1Al protein was increased after dioscin treatment, and resveratrol, an AhR antagonist, could downregulate the expression of CYP1A1. It follows that large doses dioscin has potential hepatotoxicity. The possible mechanism may be dioscin can active aryl hydrocarbon receptor (AhR) and induce the expression of CYP1A.

To research the effect of Ginseng Radix et Rhizoma and Aconiti Lateralis Radix Praeparata compatibility on cardiac toxicity in rats by UPLC-Q-TOF/MS, and explore the endogenous markers and molecule mechanism. Different compatibility of Shenfu decoction were given to male Wistar rats at dosage of 20 g · kg(-1) for 7 days, collected the serum, and analyze the endogenous metabolites effected by Shenfu formulation by principal component analysis and partial least-squares analysis. Results showed that content of glutathione, phosphatidylcholine and citric acid decreased in mixed-decoction group, while ascorbic acid, uric acid, D-galactose, tryptophan, L-phenylalanine increased. The results showed cardiac toxicity of Aconiti Lateralis Radix Praeparata in Shenfu mixed-decoction. Shenfu co-decoction group showed a similar or weaker trend compared with control group, but most of them do not have a statistically significant. The results indicated the scientific basis of Shenfu compatibility by comparison of co-decoction group with mixed-decoction group. Shenfu compatibility can reduce cardiac toxicity induced by Aconiti Lateralis Radix Praeparata, and citric acid, glutathione, phosphatidyl choline, uric acid might be regarded as potential markers of cardiotoxicity.

To study the effect of Siwu decoction on the function and expression of P-glycoprotein (P-gp) in Caco-2 cells. The Real-time quantitative poly-merase chain reaction (Q-PCR) was used to analyze the mRNA expression of MDR1 gene in Caco-2 cells. Flow cytometer was used to study the effect of Siwu decoction on the uptake of Rhodamine 123 in Caco-2 cells, in order to evaluate the efflux function of P-gp. Western blotting method was used to detect the effect of Siwu decoction on the P-gp protein expression of Caco-2 cells. Compared with the blank control group, after Caco-2 incubation with Siwu decoction at concentrations of 3.3, 5.0, 10.0 g x L(-1) for 24, 48, 72 h, the mRNA expression of MDR1 was up-regulated, suggesting the effect of Siwu decoction in inducing the expression of MDR1. After the administration with Siwu decoction in Caco-2 cells for 48 h, the uptake of Rhodamine 123 in Caco-2 cells decreased by respectively 16.6%, 22.1% (P < 0.05) and 45.4% (P < 0.01), indicating that the long-term administration of Siwu decoction can enhance the P-gp efflux function of Caco-2 cells. After the incubation of Caco-2 cells with Siwu decoction for 48 h, the P-gp protein expression on Caco-2 cell emebranes, demonstrating the effect of Siwu decoction in inducing the protein expression of P-gp.

OBJECTIVETo compare the serological characters of an outbreak of hepatitis E and evaluate sensitivity and specificity of anti-HEV E2-IgM.

METHODSThe sera collected from the employees of an outbreak unit were detected for anti-HEV E2-IgM and IgG, and the serum samples from a neighboring department were used as control. The results detected with anti-HEV E2-IgM, IgG and Genelab anti-HEV IgM, IgG in some samples were compared.

RESULTSThe positive rate of anti-HEV E2-IgM in the control group was 0.11%. The results between the positive and the negative samples can be distinguished easily. The specificity of anti-HEV E2-IgM is about 99.89%. The positive rate of anti-HEV E2-IgM in outbreak stricken population was 8.66%, significantly higher than that in the control group (P < 0.001). The results from HEV patients' serial samples in the outbreak unit showed that the anti-HEV E2-IgM titer was high 30-60 days after the infected and then declined clearly. The positivity seemed unrelated to neither sex nor age. Among the 115 positive to anti-HEV E2-IgM, 27 were negative to Genelab anti-HEV IgG, the fact indicated a rather high risk of misdiagnosis of about 23.48%. In the 179 randomized samples of the control group, the positive rate of Genelabs anti-HEV IgG was about 11.17%. In 110 samples for the positive anti-HEV E2-IgM, the positive ratio of Genelabs anti-HEV IgG was about 76.36%, and that of Genelabs anti-HEV IgM only 69.09%. There were 16 samples negative for both Genelabs anti-HEV IgG and IgM. The ratio of the difference between the Genelabs anti-HEV IgG and IgM was about 25.45%.

CONCLUSIONThe specificity of anti-HEV E2-IgM was about 99%, and false positive rate was low. The sensitivity of anti-HEV E2-IgM in acute hepatitis E infection was 25%-30% higher than that of Genelabs anti-HEV IgM,IgG. The infected persons in the outbreak unit can be preferably distinguished from the non-infected persons by anti-HEV E2-IgM. Anti-HEV E2-IgM can image the characters of the outbreak of HEV and played a great role in the control of outbreak and in the early diagnosis for hepatitis E.
