Objective To detect NF1 gene mutations in a patient with neurofibromatosis type 1 (NF1).Methods Polymerase chain reaction (PCR) and DNA sequencing were performed to detect mutations of the NF1 gene in a patient with NF1,his parents and 100 unrelated healthy controls.Results A novel frameshift mutation (c.3822delC) was identified in the patient,but not found in his parents or the unrelated healthy controls.Conclusion The novel frameshift mutation (c.3822delC) found in the patient is not a rare single nucleotide polymorphism (SNP),and may be a causative mutation for NF1 by affecting the function of the NF1 gene.

This article describes a method totransfer physiological data through carrier-current communication.The microcontroller measures the data of heartrate and body temperature and sends them through the serial port tothe carrier-current module implementing carrier-current communication.This method can be used totransfer physiological data through short distance less than200meters.

Object To study the microwave assisted procedure for the extraction of baicalin from root of Scutellariae baicalensis Georgi Methods An MSP 100D domestically made microwave sample preparation system with a maximum power of 850 watts was used. The effects of solvents, pressure/temperature of solvents and microwave radiation time on the yield of baicalin were studied by orthogonal experimental design. Results The optimal experimental conditions were extraction at 70% of microwave power with 30 times of 35% ethanol at a constant heating pressure/temperature of 0.15 MPa for 30 s. Conclusion The microwave assisted extraction not only takes a shorter time with better parallel results, but also gave an increased yield of about 10% as compared with ultrasonic extraction.

OBJECTIVETo investigate the neuro-immune regulatory mechanism of Heart Benefiting recipe (HBR), an effective recipe for treatment of Alzheimer's disease (AD).

METHODSUsing immunohistochemical and RT-PCR methods, the neuro-immunological pathological changes in the AD rat model induced by beta-amyloid protein (A beta1-40) via lateral cerebral ventricle injection, including mainly the glial fibrillary acidic protein expression and inflammatory cytokines IL-1beta, IL-6mRNA and beta-amyloid protein precursor (APPmRNA) gene expression were studied. And the effects of HBR on these parameters were observed.

RESULTSDeposition of A beta in cerebral tissue could induce activation of stellate glial cells and abnormal increased levels of inflammatory cytokines (IL-1beta and IL-6mRNA), also the elevation of APPmRNA level. HBR could effectively control the above-mentioned pathological changes.

CONCLUSIONHBR could effectively control the inflammation and the A beta immune cascade reaction in brain of AD patients, it is one of the important therapeutic mechanisms of the recipe.
