Analysis on Blood Pressure Variability and Its Influencing Factors of Hypertensive Patients with Different TCM Syndromes / 中国中医药信息杂志

Objective To investigate the TCM syndrome type distribution of hypertensive patients; To analyze the correlation of blood pressure variability (BPV) parameters and its influence factors. Methods The data of 515 hypertensive patients including demographic information, laboratory test parameters, risk factors and clinical symptoms were collected for correlation analysis and the patients were divided to different TCM syndromes. BPV parameters of 515 hypertensive patients were acquired by 24 h ambulatory blood pressure, then our study analyzed and compared the differents of 24 h MSBP, 24 h MDBP, 24 h MSCV, 24 h MDCV, DMSBP, DMDBP, DMSCV, DMDCV, NMSBP, NMDBP, NMSCV, NMDCV between different TCM syndromes. Results There were 160 cases with hyperactivity of yang due to yin deficiency syndrome, 136 cases with turbid phlegm and blood stasis syndrome, 83 cases with overabundant liver-fire syndrome, 69 cases with deficiency of kidney qi, and 67 cases with abundant phlegm-dampness syndrome. The difference of gender and age was statistically significant between different TCM syndromes (P<0.05). Compared with the group of hyperactivity of yang due to yin deficiency syndrome, the level of 24 h MSBP, 24 h MDBP, DMSBP, DMDBP, NMSBP, NMDBP, 24 h MSCV, 24 h MDCV, DMSCV, DMDCV, NMSCV and NMDCV had statistical significance in the groups of turbid phlegm and blood stasis syndrome, overabundant liver-fire syndrome, deficiency of kidney qi and abundant phlegm-dampness syndrome (P<0.05). Logistic regression analysis showed that the factors including gender (female), insomnia (time<6 h), sodium salt intake, emotion and educational level were positively correlated to hyperactivity of yang due to yin deficiency, and other factors including gender (female), age, sodium salt intake and educational level positively correlated with turbid phlegm and blood stasis syndrome. And the study also showed that age, sodium salt intake, family history of hypertension and educational level were positively correlated to abundant phlegm-dampness syndrome. Conclusion The BPV parameters and blood pressure are significantly increased d in the group of hyperactivity of yang due to yin deficiency than other groups, but decrease in the group of abundant phlegm-dampness syndrome. Hyperactivity of yang due to yin deficiency syndrome, abundant phlegm-dampness syndrome and turbid phlegm and blood stasis syndrome are closely related to the influencing factors that lead to cardiovascular and cerebrovascular events.

Application of Finite Element Method in Traffic Injury and Its Prospect in Forensic Science / 法医学杂志

The finite element method （FEM） is a numerical computation method based on computer technology, and has been gradually applied in the fields of medicine and biomechanics. The finite element analysis can be used to explore the loading process and injury mechanism of human body in traffic injury. FEM is also helpful for the forensic investigation in traffic injury. This paper reviews the development of the finite element models and analysis of brain, cervical spine, chest and abdomen, pelvis, limbs at home and aboard in traffic injury in recent years.

Investigation on measles cases of new genotype D8 in Beijing, 2013 / 中华流行病学杂志

<p><b>OBJECTIVE</b>To investigate the epidemiological characteristics of measles cases of new genotype D8 in Beijing from January to June, 2013.</p><p><b>METHODS</b>Epidemiological survey and descriptive analysis was conducted.</p><p><b>RESULTS</b>661 suspected measles were reported from January to June, 2013. 416 were confirmed measles cases by serology and etiology detection. 28 measles cases were caused by genotype D8 measles virus by genotype identification. There were 2 measles outbreak including 14 cases and 14 sporadic cases. The incidence peak was during April and May. 25 cases (89.3%, 25/28) occurred in downtown and suburban districts. 22 cases (78.5%, 22/28) were adults aged 15-39 years and 19 cases (67.9%, 19/28) were migrant population. 12 cases (85.7%, 12/14) in outbreak were migrant population working in clothing sales. There was epidemiological association between 2 outbreaks.</p><p><b>CONCLUSION</b>Measles cases of genotype D8 were found for the first time in Beijing. Genotype D8 virus mainly infected migrant adults and caused local outbreak and endemic.</p>
