[Review of the mechanism of essential hypertension treated by acupuncture].

The relevant literature of pathogenesis of essential hypertension (EH) and the clinical efficacy of acupuncture treatment of EH was retrieved from January 1, 1999 to February 28, 2018 in the CNKI and PubMed databases, and aimed to summarize and explore the mechanism of antihypertensive by acupuncture.It has been found that acupuncture exerts antihypertensive effect by coordinating multi-system, multi-target, multi-layer adjustment mechanism, such as acupuncture inhibiting of central and peripheral sympathetic nerve activity, rejusting immune system and expression of inflammatory response factors, regulating the balance of renin-angiotensin-aldosterone system (RAAS), improving vascular structure and function, the anti-oxidative stress and promoting autophagy.

A data-driven noise reduction method and its application for the enhancement of stress wave signals.

Ensemble empirical mode decomposition (EEMD) has been recently used to recover a signal from observed noisy data. Typically this is performed by partial reconstruction or thresholding operation. In this paper we describe an efficient noise reduction method.

Thickness measurement of colloidal opal crystal growth by Bragg reflection.

This study investigates a simple method for thickness estimation with single layer accuracy for self-assembling opal crystals prepared by the dip-coating method. The thickness (number of layers) of the opal crystals was estimated by an analysis of the optical reflectance from s-polarization incident light, and then verified with SEM. The opal crystals were considered as periodic dielectric layers and were analyzed with the transfer matrix method.

[Effects of deltamethrin on neurobehavioral development of offspring of intoxicated rats].

Objective: To investigate the effects of deltamethrin on the filial brain nitric oxide synthase (NOS) activity and neurobehavioral development of the exposed lactational rats.

Methods: Pregnant rats were randomizedly divided into the treated group and the control group. The treated group was administered orally with 3.
