Pulse wave, a research focus in both traditional Chinese medicine and Western medicine, which contains a wealth of human physiological and pathological information, has always been the concern of medical practitioners. On the basis of the review on the development of the pulse wave theory and its applications, the existing problems in this field are discussed in this paper. On the basis of the status quo of pulse wave information extraction methods and the utilization of pulse wave in traditional Chinese and Western medicine, a more in-depth study on pulse wave is proposed to make it a bridge connecting traditional Chinese medicine with Western medicine.

In practice of forensic medicine, potential disease can be associated with fatal asphyxia in re-straint position. Research has demonstrated that nitric oxide (NO) and nitric oxide synthase (NOS) are plentifully distributed in skeletal muscle, contributing to the regulation of contractile and relaxation. In the current study, respiratory functions, indices of diaphragmatic biomechanical functions ex vivo, as well as NO levels in serum, the expressions of diaphragmatic inducible NOS (iNOS) mRNA, and the effects of L-NNA on contractility of the diaphragm were observed in sepsis induced by cecal ligation and punc-ture (CLP) under the condition of restraint position. The results showed that in the CLP12-18 h rats, respiratory dysfunctions; indices of diaphragmatic biomechanical functions (Pt, +dT/dtmax, -dT/dtmax, CT, Po, force over the full range of the force-frequency relationship and fatigue resistance ) declined progressive-ly; the NO level in serum, and iNOS mRNA expression in the diaphragm increased progressively; force increased significantly at all stimulation frequencies after L-NNA pre-incubation. Restraint position 1 h in CLP12 h rats resulted in severe respiratory dysfunctions after relative stable respiratory functions, almost all the indices of diaphragmatic biomechanical functions declined further, whereas little change took place in NO level in serum and diaphragmatic iNOS mRNA expression; and the effects of L-NNA were lack of statistical significance compared with those of CLP12 h, but differed from CLP18 h group. These results suggest that restraint position and sepsis act together in a synergistic manner to aggravate the great reduction of diaphragmatic contractility via, at least in part, the negative modulation of NO, which may contribute to the pathogenesis of positional asphyxia.

Objective To study the effect of auricular point sticking on the cerebrovascular reactivity in hypertension patients of different stages by using Transcranial Doppler (TCD) technology.Method Three hundred hypertension patients were randomized into a treatment group (auricular point sticking) of 180 cases and a control group (medication) of 120 cases. The cerebral arterial hemodynamic indexes were observed and analyzed by TCD before and after intervention.Result In comparing the improvements of cerebral arterial hemodynamic indexes in stage 1-2 hypertension patients, the treatment group was significantly superior to the control group (P＜0.05,P＜0.01); in stage 3 hypertension patients, the improvements of cerebrovascular hemodynamics of the treatment group were significantly better than those in the control group (P＜0.05,P＜0.01).Conclusion Auricular point sticking can improve the cerebrovascular hemodynamics and effectively improve the cerebrovascular reactivity of hypertension patients. TCD can help observe and estimate the cerebral arterial function of hypertension patients, and prevent and intervene in cerebrovascular diseases.

Objective To investigate the correlation of ERα gene PvuⅡ ,XbaⅠ and ERβ gene RsaⅠ ,AluⅠ digestion polymorphism with coronary atherosclerotic heart disease(CHD) risk factors in Yancheng area .Methods A total of 124 cases of CHD and 163 persons undergoing physical examination served as the CHD group and CON group .The enzyme method was adopted to detect TG and TC .The direction method was adopted to detect HDL and LDL .ERα gene PvuⅡ ,XbaⅠ and ERβ gene RsaⅠ ,AluⅠ digestion polymorphisms were detected by adopting RFLP-PCR .Results The ratios of smoking history ,family history ,complicating hypertension and diabetes ,and the level of body mass index ,TC ,TG and LDLC in the CHD group were significantly higher than those in the control group ,the difference was statistically significant (P＜0 .05) .The various indicators had no statistically difference between male and female(P＞0 .05) .The frequency distribution and geographic distribution of ERα gene PvuⅡ ,XbaⅠ and ERβ gene RsaⅠ ,Alu Ⅰ digestion polymorphisms had no difference between the two groups ,all conformed to Hardy-Weinberg genetic equilibrium and had the group representativeness .pp ,xx ,RR and AA genotypes in the CHD group were maximal ,while PP , XX ,rr and aa genotypes were minimal ;Pp ,xx ,RR and AA genotypes in the CON group were maximal ,while PP ,XX ,rr and aa genotypes were minimal .The distribution frequency of p and x genes in the CHD group was significantly higher than that in the control group ,the difference was statistically significant(P＜0 .05) .Conclusion The estrogen gene polymorphism might be a target spot for effectively treating CHD ,and p and x gene distribution frequency may be related with CHD risk factors .
