Objective: To investigate the role of miR-19a/b in myocardial ischemia reperfusion injury (R/I) with its clinical significance. Methods: Our research included in 2 parts. Part 1: in H9c2 cells. miR-19a/b expression in H9c2 cells with 10 h hypoxia and 2 h re-oxygenation was detected by real-time PCR, miR-19a/b potential target gene was assessed by luciferase reporter activity assay. Part 2: in natural person. Control group,n=40 healthy subjects and AMI (acute myocardial infarction) group,n=40 relevant patients. Peripheral blood levels of miR-19a/b were detected as Part 1, cTnI were measured by chemiluminescence immune analysis and CK-MB were assessed by immune inhibition method. Results: Part 1: Compared with normal H9c2 cells, miR-19a/b expressions were increased 5.876 times and 2.761 times in H9c2 cells with 10 h hypoxia and 2 h re-oxygenation, bothP<0.01. With respectively transfected miR-19a/b mimic and inhibitor, miR-19a/b expression was up-regulated and down-regulated respectively. miR-19a/b and chromosome-10 deleted phosphatase, tensing homolog gene (PTEN) had the targeting effect. With up-regulated miR-19a/b expression, PTEN level was decreased and with down-regulated miR-19a/b expression, PTEN level was increased. Part 2: Compared with Control group, AMI group had elevated blood level of miR-19a/b,P<0.01. In AMI patients, miR-19a/b was increasing at 0-3 h of chest pain and reaching the peak at 6-12 h; CK-MB enzyme activity and cTnI content were elevating at 2-6 h of onset and reaching the peak at 24 h. Conclusion: miR-19a/b expression was up-regulated by myocardial ischemia reperfusion in H9c2 cells, PTEN was the potential target gene of miR-19a/b. Circulating miR-19a/b might be used as a new non-invasive biological marker for myocardial ischemia R/I diagnosis.

Objective To investigate the correlation between white matter hyperintensities (WMH)and hyperintense vessel sign (HVS) on fluid-attenuated inversion recovery (FLAIR) magnetic resonance imaging(MRI)in old adults and to explore the risk factors and pathogeneses of WMH.Methods We retrospectively collected imaging and clinical data of patients who had received both head and neck CTA and brain MRI within one month at our hospital from 2013 to 2016.The Fazekas visual scale was used to evaluate periventricular white matter hyperintensity(PWMH)and deep white matter hyperintensity(DWMH)in each brain hemisphere.According to the presence or absence of HVS in a cerebra[hemisphere,patients were assigned into an HVS-positive group or an HVS-negative group.Clinical data,PWMH,and DWMH differences were compared between the two groups.Results A total of 271 patients(542 cerebral hemispheres)were included in this study.HVS-positive imaging occurred in 79(14.6％)cerebral hemispheres and negative imaging was observed in 463 (85.4％) cerebral hemispheres.There was a significant difference between the HVS-positive and negative groups in the ipsilateral CIA stenosis(x2 =126.840,P＜0.01).The incidence of ipsilateral severe carotid artery stenosis in the HVS-positive group was 62.0％ (49/79),which was significantly higher than 9.9％ (46/463)in the HVS-negative group.The incidence of moderate-severe DWMH was 65.8％(52/79) in the HVS-positive group,which was higher than 34.8％ (161/463)in the negative group(x2 =34.962,P ＜20.01).Nevertheless,the incidences of moderate-severe PWMH in the two groups were 65.8％ (52/79) and 55.5％ (257/463),respectively,without a significant difference between them (x2 =6.944,P =0.074).After adjusting for age,gender,ipsilateral ICA stenosis,hypertension,diabetes,etc.multivariate analysis suggested that HVS-positive imaging was still an independent risk factor for DWMH(OR =2.653,95％CI:1.489-4.726,P =0.001).Conclusions HVS-positive imaging is an independent risk factor for DWMH in the elderly,but no clear correlation with PWMH is found.It suggests that hypoperfusion is a possible mechanism for the development of DWMH in the elderly.

To establish an HPLC method for determination of dactylorhin A and militarine in Cremastrae Pseudobulbus/Pleiones Pseudobulbus. The analysis was achieved on an Alltech Prevail C18 column (4. 6 mm x 250 mm, 5 microm) using a mobile phase of acetonitrile (A), water (B) gradient elution in a total run time of 35 min (0 min, 20:80; 30 min, 55:45; 35 min, 55:45) and a diode array detector was set at 224 nm. The flow rate was 0.8 mL x min(-1). The assay displayed good linearity over the concentration range of 0.257-9.95 microg (r = 0.999 8), and 0.128-10.27 microg (r = 0.999 9), respectively. The average recoveries (n = 9) were 94.70% and 102.8% for dactylorhin A and militarine, respectively. The method is accurate, quick, simple and reproducibility. It can be used for the quality control of Pleione bulbocodioides and Pleione yunnanensis.

A comparable study were carried out by determination of trace elements on five marine-derived shell traditional Chinese medicine (TCM) (Ostreae Concha, Haliotidis Concha, Margaritifera Concha, Meretricis Concha, and Arcae Concha), which were recorded in the Chinese Pharmacopoeia (2010 version). Seven trace elements in 51 batches of this type of shell TCM were analyzed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS), combined with principal component analysis (PCA) methods. The content of element Se, which exhibited significant differences among different drugs, could be used as a key element to distinguish this type of drugs. Meanwhile, the contents of elements Co, Cu, Mo, and Ba in Haliotidis Concha, Co and As in Margaritifera Concha, Mo and As in Meretricis Concha, Mo, As, and Ba in Arcae Concha, and Zn in Meretricis Concha were relatively stable. In the PCA plot, Arcae Concha and Meretricis Concha could be efficiently distinguished from Ostreae Concha together with Haliotidis Concha, and Margaritifera Concha. The results also showed a correlation with their medicinal function. In conclusion, trace elements in marine-derived shell TCM could not be neglected for their quality control.
