Objective To evaluate the value of left ventricular energy loss (EL) in the systolic left ventricular hemodynamic changes in hypertensive patients by ultrasonic flow vector imaging (VFM). Methods Ninty-eight hypertensive patients were divided into non left ventricular hypertrophy group (NLVH group) and left ventricular hypertrophy group (LVH group) according to the left ventricular mass index(LVMI).Thirty-one healthy adults were erolled as control group.The average total energy loss (EL-T),basal energy loss (EL-B),middle energy loss (EL-M) and apical energy loss (EL-A) of each isovolumic contraction phase,fast ejection phase and slow ejection phase were obtained by VFM,the difference among the three groups were compared.Results ①EL-T and EL-B in isovolumic phase,rapid ejection phase and slow ejection phase in NLVH group were higher than those in control group ( P <0.05 or P <0.01);EL-T,EL-B,EL-M and EL-A in isovolumic phase,rapid ejection phase and slow ejection phase in LVH group were all higher than those in control group ( P <0.05 or P <0.01);EL-M in isovolumic phase and rapid ejection phase,EL-T,EL-B,EL-M and EL-A in slow ejection phase in LVH group were higher than those in the NLVH group ( P <0.05 or P <0.01).② There was a positive correlation between EL-T and LVMI (r=0.311, P < 0.01),EL-B and LVMI ( r = 0.219, P < 0.05),EL-M and LVMI( r = 0.207, P <0.05),EL-T and LVEF( r = 0.340, P < 0.05),EL-B and LVEF( r = 0.367, P < 0.01) in isovolumic contraction phase.There was a positive correlation between EL-B and LVEF( r = 0.359, P < 0.01) in rapid ejection phase.There was a positive relation between EL-B and LVEF( r =0.352,P <0.05) in slow ejection phase.Conclusions The EL of systolic peroid in hypertensive patients increased,which suggests that the left ventricular hemodynamic changes abnormally,VFM can accurately evaluate the changes of hemodynamic during systole.

Objective The aim of this study is to detect the mRNA and protein expression levels of ERCC1 and XPF genes among different age groups of healthy Chinese Han individuals,and to analyze the correlation between the mRNA and protein expression levels andthe age of individuals in order to find new molecular markers for forensic age estimation.Methods Peripheral blood samples were obtained from 150 unrelated healthy Chinese Han individuals.The plasma was centrifuged from the whole blood by gradient centrifugation,and the totalRNA was extractedwithTrizol fromperipheral blood mononuclear cells(PBMCs).Real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR) was used to quantitatively analyze the mRNA relative expression levels of ERCC1and XPF in PBMCs.Enzyme linked immunosorbent assay (ELISA) was used to quantitatively analyze the protein expression levels of ERCC1and XPF in plasma.Results There were no significant differences in the mRNA relative expression levels of ERCC1 and XPF in PBMCs between males and females(P＞0.05).Significant differences were found in the mRNA relative expression levels of ERCC1 and XPF between different age groups (P＜0.05).Regression analysis showed thatthe mRNA relative expression levels of ERCC1 and XPF were both negatively correlated with age.The correlation coefficients(r) were-0.578 and-0.844,respectively.When the age was used as independent variable(x) and the mRNA expression relative level as dependent variable (y),the fitting curveswere Y=3.3E-5X2-0.0261X+1.9175 (R2=0.3244,P＜0.01),Y=0.0003X2-0.0459X+2.0439 R2=0.729,P＜0.01),respectively.There were no significant differences inthe protein expression levels of ERCC1 and XPF in plasma between different age groups or genders (P＞0.05).Conclusion The mRNA relative expression levels of ERCC1 and XPF in PBMCsdeclined with the increase of age,however,the protein expression levels in plasma were unrelated to age.ERCC 1 and XPF genes can be used asnew molecular markers for forensic age estimation,so as to providetheoretical basis for establishing the mathematical model of ERCC1/XPF genesin concern ofindividual ages.

Tongluo Xingnao effervescent tablet (TLXNET) is a patented prescription, which comes from modified Xionggui decoction and can improve cognitive function. However, its effect on the urine metabolites and anti-dementia mechanism in the dementia model rats induced by hippocampal injection with Aβ25-35 remains unclear. The experiment focused on the changes in trajectory and inter-relationship among the urinary metabolite of rats in the blank group, Aβ25-35 hippocampal injection dementia model group and the TLXNET intervention group, in order to determine theirs characteristic metabolic markers and explain the anti-dementia effect of TLX-NET base on the change of metabolic trajectory of these bio-markers. According to the experimental results, 5, 6-indolequinone, 4-hydroxyphenyl pyruvic acid (4-HPPA), cortisol and 3-thiosulfate lactic were preliminarily identified as the characteristic metabolic markers. They mainly participate in dopamine system, glucocorticoids and energy metabolic pathways. TLXNET can apparently downregulate the disturbances of metabolic trajectory of the four bio-markers. The experiment indicates that the dementia model induced by injecting Aβ25-3 into hippocampus has its characteristic endogenous metabolic markers in urine, and ELXNET can ameliorate dementia by down-regulating the disturbances of metabolic trajectory.

OBJECTIVE: To explore the growing development and community succession of main sarcosaphagous insects on pig carcasses in summer indoor and outdoor environment in Shenzhen area and to estimate the postmortem interval (PMI). METHODS: From early May to August in 2013, in Forensic Medical Examination Center of Shenzhen Public Security Bureau, the main insect species and the decomposition process were observed in two adult pig carcasses of simulative indoor and outdoor environment. The different decomposition stages and the community succession of insects were recorded. RESULTS: The indoor and outdoor pig carcasses showed skeleton 412.5 and 325 hours after death, respectively. The main species of flies on pig carcasses were Chrysomya megacephala, Chrysomya rufifacies and Chrysomya chani. The main species of beetles were Crecphilus maxillosus, Necrobia ruficollis, Saprinus splendens and Dermestes maculatu. The dominant species of flies in the outdoor pig carcasses obviously produced the second generations due to the effect of mass rainfall, nor in the indoor pig carcasses. CONCLUSION There are regular patterns on the community succession of insects on pig carcasses in summer indoor and outdoor environment in Shenzhen area. The activity patterns of seven typical insects and their larva show important value for estimating PMI.

Osteoarthritis (Osteoarthritis, OA) is a common clinical degenerative joint disease with increased incidence rate in recent years. Animal experiment is one of the important ways to explore pathogenesis and treatment of OA, while induced animal model is the most important part in animal experiment. Intra-articular injection of drugs is a classical method for establishing animal model of OA. Choose of animal should follows the principle of correlation, appropriateness and practicability, injections should perform in accordance with experimental purposes and subject, detections means and evaluation methods also should corresponding to experimental reality. The gold standard of OA animal model and intra-articular injections has not build, need further study.
