1.Portable instrument for arteriosclerosis assessment.
Chinese Journal of Medical Instrumentation 2014;38(1):6-10
A portable instrument for arteriosclerosis assessment containing sensor module, acquisition board and embedded module was developed for home care in this paper. The sensor module consists of one ECG module and three pulse wave extraction modules, synchronously acquiring human ECG and pulse wave signal of carotid, radial, and dorsal, respectively. The acquisition board converts the sensor module's analog output signals into digital signals and transmits them to the embedded module. The embedded module realizes the functions including signal display, storage and the calculation and output of pulse wave velocity. The structure of the proposed portable instrument is simple, easy to use, and easy to expand. Small size, low cost, and low power consumption are also the advantages of this device. Experimental results demonstrated that the proposed portable instrument for arteriosclerosis assessment has high accuracy, good repeatability and can assess the degree of atherosclerosis appropriately.

2.Advances in moyamoya disease
International Journal of Cerebrovascular Diseases 2009;17(9):700-704
Moyamoya disease is a cerebrovascular disease that is characterized by the progressive stenosis in the terminal internal carotid artery, the anterior cerebral artery and the origin of the middle cerebral artery, and compensatory enlargement of basal perforating artery. Both the genetic and environmental factors involxe in its pathogenesis. but its exact cause is unknown. Revascularization is the main treatment approach for moyamoya disease. This article reviews the progress in research on epidemiology, etiology, diagnosis and treatment of moyamoya disease.
3.The application of translational medicine in cultivating postgraduates of neurology

5.Adjunctive efficacy of microbial ecological agents for elderly patients with acute pancreatitis
Chinese Journal of Geriatrics 2013;(6):627-629
Objective To explore the auxiliary efficacy of microbial ecological agents for elderly patients with acute pancreatitis.Methods Totally 144 elderly patients with acute pancreatitis were selected and randomly divided into the observe group and the control group (n=72,each).All patients received the regular treatment and enteral nutrition.Microbial ecological agents were added in enteral nutrition in the observe group.The levels of endotoxin (ET),tumor necrosis factor (TNF-α),interleukin (IL)-6 and C-reactive protein (CRP)in peripheral blood were determined and compared between the two groups.The clinical index and the occurrence of adverse reactions were observed.Results Compared with pretreatment,the levels of ET,TNF-α,IL-6,CRP were significantly reduced in both two groups after treatment.The levels of ET,IL-6,TNF-α,CRP were lower in the observe group than in the control group [(0.14±0.07)EU/ml vs.(0.31±0.12)EU/ml,(44.77±17.82)pg/ml vs.(63.25 ± 14.26)pg/ml,(0.15 ± 0.05)μg/L vs.(0.29 ± 0.14)μg/L,(108.33 ±11.84)mg/Lvs.(135.41±21.45)mg/L,t=14.722,43.824,7.071,5.811,respectively,allP<0.05].The recovery time of symptoms and signs,the anal exsufflation time and hospitalization time were shorter in the observe group than in the control group [(25.8±4.8)h vs.(36.4±6.2)h,(30.9±6.7)hvs.(44.4±7.3)h,(24.9±3.2)hvs.(37.6±3.4)h,(6.9±0.4)dvs.(13.1±1.2)d,t=4.747,4.401,10.125,33.443,respectively,all P<0.05].There were no statistically differences in death rate and the occurrence of adverse reactions between the two groups (x2 =0.15,0.64,both P>0.05).Conclusions Microbial ecological agents are safe and effective as an adjuvant therapy for elderly patients with acute pancreatitis.It is worth promoting in clinical medicine.

Objective To determine whether NT 3 overexpression could abrogate DDP toxicity in vitro . Methods We constructed a herpes simplex virus(HSV) amplicon vector to transduce a c myc tagged version of rat NT 3. In the HSVnt 3myc vector, the chimeric neurotrophin cDNA was placed under the transcriptional control of the CMVIE promoter. The resultant vector was packaged utilizing the recently developed helper virus free method. Results Transduction of NT 3myc in cultured mouse cochlear explants at a multiplicity of infection(MOI) of 0 25 resulted in production of NT 3 up to 3?g/L over a 48 hours period. The mouse cochlear explants were transduced with HSVnt 3myc or HSVmiap(control vector expressing the reporter gene, murine intestinal alkaline phosphatase) for 48 hours and the exposed to cisplatin for 48 hours.The cochlear explants transduced with HSVnt 3myc had a significantly greater number of SGN survival than the control group. NT 3 powerfully enhanced the process length and the density of SGNs.Conclusion These data demonstrate that the neurotrophic cDNA transduction via HSV amplicon helper free virus system can attenuate the ototoxic action of DDP on organotypic culture. The potency of NT 3 in protecting spiral ganglion neurons from degenerating suggests that neurotrophins might be useful for the prevention or treatment of hearing disorders. [

International Journal of Laboratory Medicine 2015;(6):791-792,795
Objective The multiple polymerase chain reaction(PCR) technique was adopted to detect AZF microdeletion of Y chromosome in 120 patients with idiopathic oligozoospermia and azoospermia and contemporaneous 60 cases of normal semen rou‐tine examination in the outpatient department .At the same time the peripheral blood chromosome karyotype analysis was performed on these 120 patients .Methods Multiple PCR (Polymerase chain reaction) technique were used to analyze 15 locus of the azoosper‐mia factor (AZF) in the 120 patients with idiopathic azoospermia and oligozoospermia and 60 mormal cases .using the Karyotype a‐nalysis technique to analyze karyotype of the 120 male infertile patients ,at the same time .Results Among 120 cases of male infer‐tility ,no obvious abnormal karyotype was found .23 cases were detected AZFc deletions with the detection rate of 19 .2% ,no mi‐crodeletions at other loci were detected .Conclusion AZFc is the major candidate gene for AZF gene screening in male infertility pa‐tients from this area .The Y chromosome microdeletion is the important cause leading to male infertility .
9.Perinatal infection and asthma in the infant
International Journal of Pediatrics 2010;37(1):20-22
Epidemiological and clinical studies have provided compelling evidence that suggests a link between the relative lack of infectious diseases and the increase in allergic disorders. Asthma usually starts early in life. The early occurrence of asthma suggests that prinatal influences are of importance.Prenatal or postnatal exposure to endotoxins and other bacterial products may protect against the development of asthma in the infant. We will briefly outline the current state of the relationship of the perinatal infection and asthma in the infant, and focus our review mainly on possible rneehanism of perinatal infection providing protection against asthma in the infant, such as Th1/Th2 immune system, transcription factors, protection by maternal antibodies, endotoxin tolerance, pulmonary inflammation and genetic influences.
