Objective To study the effects of Panax Notoginseng Saponins (PNS) on the damaged expression of ZO-1 of brain microvascular endothelial cells caused by Aβ42.MethodsBrain microvascular endothelial cells were divided into normal control group, model group, PNS low-, medium- and high concentration groups. They were incubated for 24h in 5% CO2 incubator at 37℃ . Then cell vitality was detected by MTT colorimetric method and ZO-1 protein expression was tested by Western blot.Results Stimulation of Aβ42 reduced the activity of microvascular endothelial cells (P<0.01) and suppressed the expression of ZO-1 protein (P<0.01). Compared with the model group, the activity of microvascular endothelial cells of PNS groups, especially the high and medium dose groups (P<0.05), and increased the ZO-1 protein expression. Conclusion PNS can partly recover the barrier function of blood brain barrier through inhibiting the decrease of the activity of microvascular endothelial cells caused by Aβ42.

Objective To observe the effects of Fuzheng Huayu Capsule on the expressions of the main roles, Rock1 and Rock2, in RhoA/Rock signal transduction pathway in rats with myocardial infarction (MI);To explore the possible mechanism of Fuzheng Huayu Capsule to improve ventricular remodeling in myocardial fibrosis. Methods The MI model was induced by ligation of the left coronary artery. Rats with MI were randomly divided into the model group, Fuzheng Huayu group and Fasudil hydrochloride group. A sham-operation group threading without ligation was setting as a control group, with eight rats in each group. The rats were treated with corresponding medicine for 4 weeks from the second day after modeling. The expression of Rock1, Rock2 and its mRNA were detected by immunohistochemical and real-time PCR method.

The protein expression of Rock1 and Rock2 in the Fuzheng Huayu group and Fasudil hydrochloride group were lower than those in the model group. The mRNA expression of Rock2 was significantly higher in the model group than that in the sham-operation group (P<0.05). The mRNA expression of Rock1 in the Fasudil hydrochloride group was lower than that in the model group (P<0.05). The mRNA expression of Rock2 in the Fuzheng Huayu group and Fasudil hydrochloride group was lower than that in the model group (P<0.05). Conclusion Fuzheng Huayu Capsule can decrease the expression of Rock1, Rock2 and Rock2 in the marginal zone of myocardial infarction in rats with MI. The anti ventricular remodeling mechanism of Fuzheng Huayu Capsule maybe related with this.

Objective:To analyze the bubble dynamic characteristics of shock wave enhanced emission photoacoustic streaming(SWEEPS)technique in free water region under different temporay delays.Methods:The Er∶YAG laser tip was activated in free water model with SWEEPS mode at 150-600 μs pulse delay.The bubble dynamic process during irrigation was recorded by a high-speed camera(200 000 Hz).Matlab was used to analyze the interaction between bubble made by the dual pulses frame by frame.The distance between bubble remnants and laser tip was measured before the bubble disappeared.The experimental data were statisti-cally analyzed by SPSS 19.0.Results:In free water region,different temporal delays caused different interaction between the bub-bles activated by the SWEEPS technique with a dual pulse modality.The interactions include bubble fusion,bubble collision and bubble separation.When the temporal delay between 360-440 μs,bubble collision was the most violent,and the farthest distance between bubble remnants and laser tip was reached.Conclusion:In free water region,the dual pulse of SWEEPS technique can lead to bubble interaction which may enhance the cavitation effect of Er∶YAG laser irrigation,and improve the debridement in clinic ap-plication.

OBJECTIVE To investigate the variations in taste, aroma and volatile organic compounds of Rhei Radix et Rhizoma decoction pieces derived from different sources, and to identify their origins. METHODS The flavor, odor and volatile organic compounds of Rhei Radix et Rhizoma decoction pieces from different sources were compared and analyzed by using electronic tongue, electronic nose, and gas chromatography-ion mobility spectrometry (GC-IMS). Principal component analysis (PCA), partial least squares-discriminant analysis (PLS-DA), orthogonal partial least squares discriminant analysis (OPLS-DA) and Fisher discriminant analysis were employed to identify the origins of Rhei Radix et Rhizoma decoction pieces and establish the basis discrimination criteria. RESULTS The differences in taste of Rhei Radix et Rhizoma decoction pieces from 3 origins were primarily characterized by bitterness, astringency, and bitter-astringent aftertaste. In terms of smell, variations were mainly observed in inorganic sulfides, organic sulfides containing aromatic components, methane and other short-chain alkanes, alcohols, ethers, aldehydes and ketones, as well as nitrogen oxides. Differentially volatile organic compounds mainly consisted of alcohols, aldehydes and ketones. Furthermore, the samples from 8 batches could be effectively classified into 3 categories.Three types of Rhei Radix et Rhizoma decoction pieces can be effectivily identified based on the peak intensity ratio between volatile substances. For example, when the peak intensity of 2-acetylfuran was 3-19 times that of isobutyric acid [dimer], it was considered as Rheum officinale Baill. CONCLUSIONS The discriminant models established in this study, along with the criteria for determining the origins based on the peak intensity ofcharacteristic volatile compounds, can be utilized for the identification of Rhei Radix et Rhizoma decoction pieces.

OBJECTIVETo investigate the sensitivity and specificity of eosin-5'-maleimide (EMA)assay for the diagnosis of hereditary spherocytosis (HS), and to verify the stability of reagent and samples.
METHODSEMA flow cytometry test, NaCl-osmotic fragility test and acidified glycerol lysis test were performed using peripheral blood samples from 80 patients with HS and 44 patients with other blood diseases, the sensitivity and specificity of the three methods were compared, and the feasibility of EMA binding test was estimated. The stability of EMA reagent and HS samples stored at different temperatures were tested.
RESULTSAmong the 124 tested samples, the sensitivity and specificity of EMA binding test was 0.925 and 0.954, that of NaCl-osmotic fragility test was 0.950 and 0.455, and that of acidified glycerol lysis test was 1.000 and 0.318, respectively. Although the sensitivity of NaCl-osmotic fragility test and acidified glycerol lysis test was a little higher than that of EMA binding test, the specificity of the former two methods was poor, they couldn't clearly distinguish whether spherocytosis is hereditary spherocytosis. The experiment results showed that EMA was sensitive to the temperature and should not be stored in a small aliquots at -80 ℃ over a period of 6 months. The stability of the HS sample was better, 6 days storage at 4 ℃ and 3 days storage at room temperature had no influence on the results.
CONCLUSIONEMA binding test by flow cytometry showed good sensitivity and specificity for HS diagnosis. EMA reagent should be stored at-80 ℃ and the HS samples should be tested within 6 days storage at 4 ℃ and 3 days at room temperature.
