Objective To observe the clinical efficacy of modified Yiqi Shengjiang Decoction for chronic heart failure (CHF) and its effects on BNP and LP-PLA2. Methods Totally 100 cases of patients with CHF were randomly divided into treatment group and control group, with 50 cases in each group. The control group received basic treatment, and the treatment group was treated with modified Yiqi Shengjiang Decoction on the basis of control group, one dosage per day, twice a day, orally, for 4 weeks. The curative effect of heart function grading and curative effect of TCM symptoms of the two groups, the changes of plasma BNP and LP-PLA2 levels were observed. Safety indicators were monitored. Results The total effective rate of cardiac function classification was 88％ (44/50) in the treatment group and 68％ (34/50) in the control group, with the treatment group much better than the control group (P<0.05); the total effective rate of TCM symptom efficacy was 90％ (45/50) in the treatment group and 74％ (37/50) in the control group, with the treatment group much better than the control group (P<0.05). The BNP and LP-PLA2 levels in the treatment group were lower than the control group after treatment, with statistical significance (P<0.05). No adverse reactions were observed in both groups, with no abnormalities in blood, urine, liver and kidney function. Conclusion Modified Yiqi Shengjiang Decoction combined with Western medicine has obvious advantages in the treatment of CHF in improving patients' heart function, and reducing plasma BNP and LP-PLA2 levels.

Distribution characterization of 29 virulence genes in 91 foodborne Listeria monocytogenes strains / 中国人兽共患病学报

In order to study the distribution of virulence genes of Listeria monocytogenes (Lm) in Hebei Province,29 virulence genes of Lm,including Listeria monocytogenes pathogenicity islands Ⅰ (LIPI-Ⅰ:prfA,plcA,plcB,hlyA,mpl and actA),10 internalins genes (inlA,inlB,inlC,inlD,inlE,inlF,inlG,inlH /C2,inlI and inlJ) and the other 13 virulence-associated genes (bsh,srtA,iap,sigB,virR,mprF,dltA,dltB,dltC,dltD,srtB,fbpA and hpt) were detected by PCR.Results showed that in the 91 Lm strains,the detection rate of 23 virulence genes were 100％.The 29 virulence genes of 26 Lm strains were all detected,and 65 Lm strains had different deletion of 6 virulence genes inlD,inlF,inlG,inlH /C2,inlJ and mpl.The deletion rate of inlG and inlF were 60.44％ and 54.95％,respectively,following by mpl gene,with a deletion rate of 19.78％.According to the absence of virulence genes,91 strains could be divided into 10 subtypes,and the dominant virulence subtypes was type Ⅰ with all 23 virulence genes.The deletion rate of virulent genes in Shijiazhuang was higher than that in northern Hebei.It is suggested that the rate of virulence gene of food-borne Lm in Hebei Province is high,and the virulence gene deletion patterns has diversity and regional differences.

Updated molecular genetic mechanisms of globozoospermia / 中华男科学杂志

Globozoospermia is a rare and serious teratozoospermia, which is one of the important causes contributing to human male infertility. The assisted reproductive technique remains the only means for such patients to produce offspring. However, the pathogenesis of globozoospermia is not yet clear. In recent years, related studies have shown that some genes are connected with the onset of globozoospermia. This paper outlines the progress in the studies of pathogenicity genes, aiming to contribute to the molecular diagnosis and mechanism investigation of the disease.

OBJECTIVE@#To explore the characteristics of the dismembered homicide cases in Shanghai and to provide the valuable guidance for forensic pathological practices.@*METHODS@#Twenty-four cases of dismembered homicides were selected from 2005 to 2012 in Institute of Forensic Science, Shanghai Public Security Bureau. The general information of the victims and suspects, cause of death, criminal motive, postmortem body parts, tools and information of discarding body parts were retrospectively analyzed.@*RESULTS@#Among the 24 dismembered homicide cases, victims were female in 16 cases, and suspects were male in 23 cases and were acquaintances in 22 cases. The main causes of death were mechanical asphyxia and traumatic brain injury. Most of the criminal motives were emotional disputes. The number of postmortem body parts was commonly from 20 to 30. The tools were mainly sharp instruments, including kitchen knives used in 20 cases. The postmortem body parts were discarded to different transregional areas, mainly using vehicles.@*CONCLUSION@#The dismembered homicide cases in Shanghai show the following characteristics: the number of postmortem body parts is in large quantity; the methods of dismembered corpse are complex and different; the job characteristics of suspects are difficult to determine; the distance from homicide scene is far and the vehicles are commonly used.

Cardioprotective effects of limb ischemic postconditioning by different strength and time in rabbits / 中国应用生理学杂志

<p><b>OBJECTIVE</b>In this study, we try to find the better protocol of limb ischemia postconditioning by observing different protective effects of limb ischemic postconditioning (different strength and time windows in rabbits).</p><p><b>METHODS</b>42 healthy New Zealand rabbits were randomly divided into 7 groups (n = 6): Sham; Control (CON); Skeletal muscle postconditioning (SP); 6 min-delayed skeletal muscle postconditioning (6M-DSP); 1 min-delayed skeletal muscle postconditioning (1M-DSP); Strengthen skeletal muscle postconditioning (SSP); Weakened skeletal muscle postconditioning (WSP). Acute ischemia/reperfusion (I/R) model was induced by 45 minutes occlusion on left circumflex coronary artery (LCX) and 2 hours reperfusion in all anesthetized open-chest rabbits except the Sham. Limb ischemia was induced by external iliac arteries occlusion and reperfusion through artery clamps. The extent of myocardial infarction was assessed by triphenyltetrazolium (TTC) staining. Blood serum creatine kinase (CK) activity and lactate dehydrogenase (LDH) activity were measured at baseline,the end of ischemia, after 1 hour and 2 hours of reperfusion respectively.</p><p><b>RESULTS</b>Compared with the CON, the weight ratio and area ratio of myocardial infarction size were significantly decreased by 49.97% and 43.78% in SP, by 42.32% and 42.68% in 1M-DSP, by 48.36% and 48.86% in SSP (P < 0.05). But there was no significant difference between SP and 1M-DSP and SSP (P > 0.05). Otherwise, compared with the CON, myocardial infarct size was not significantly reduced in 6M-DSP or WSP (P > 0.05). The change of CK was similar to the trend of myocardial infarct size.</p><p><b>CONCLUSION</b>The limb ischemia strength of 5 mini/1 minR x 1 cycle could significantly reduce the myocardial ischemia/ reperfusion injury in rabbits, if it was achieved before myocardial reperfusion.</p>
