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.

A multi-channel meridian impedance detector used to the 3D meridian visualization positioning is presented. The detector is designed with the four-electrode method based on current driving according to low impedance of the meridian. The detector consists of power-supply module, sinusoidal signal generator, voltage-controlled current source, isolation amplifiers, filter circuit, amplitude detectors and so on.

Objective Identifying the factors of psychological pressure from medical disputes on clinical doctors and possible solutions. Methods Self-rating Anxiety Scale (SAS) and the Occupational Stress Indicator (OSI) were called into play, to study 52 clinical doctors in a tertiary hospital in a city, who had encountered medical disputes in recent two years. In parallel, 63 clinical doctors without such disputes and 50 non-clinical workers were randomly selected as the control group for questionnaires. Results Clinical doctors with such an experience were commonly found to be anxious, and their SAS score (58. 27±11.38)averaged higher than those in the control group. Doctor-patient relationship, legal liabilities and clinical positions were found to be positively correlated to psychological pressure of clinical doctors. Conclusions Medical disputes tend to add to psychological pressure of the doctors. Clinical doctors deserve psychological counseling and training and improvement of their working conditions.

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.

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.

The increasing need for ideal body shape makes more and more patients choose to receive different types of breast reconstruction surgery after mastectomy. Right now, it is a key problem for the multidisciplinary treatment to find an optimal sequence of comprehensive treatment from which those patients can receive the maximum benefits and a good balance between ideal body shape and satisfactory antitumor outcomes. This paper reviews the latest research advances in the effect of postoperative radiotherapy on breast shape after breast reconstruction, the sequential relationship between the replacement of the temporary tissue expander with the permanent breast prosthesis and postoperative radiotherapy, breast construction surgery, and radiotherapy techniques. To provide a basis for clinical practice, this paper proposes a flow chart for decision?making in reconstruction surgery and adjuvant treatment based on the current literature and clinical data.

Precision medicine significantly promotes the diagnosis and treatment of various diseases,which also induces the revolution of evidence-based clinical practice guidelines,as well as multimodality therapy for hepatocellular carcinoma (HCC).In the application of the concept of precision medicine and evidence-based medicine,surgeons will concretize the precise surgery,establish an improved multimodality therapy for HCC,and ultimately achieve the goal of overall benefit.This is also a new task of surgeons in the precision medicine era.

OBJECTIVE:To observe the effects of the essential conditions of storage on quality of Semen Armenniacae Am_arum (SAA).METHODS:Gravimeteric and titration method were used and orthogonal design was adopted.RESULTS:Obvious effects of baking temperature and storage duration on content of amygdalin,temperature on acid value of SAA,temperature and humidity and storage duration on peroxide value of SAA were found.CONCLUSION:The best conditions of storing SAA are as follows:A1,B1,C3 and short storage duration.

Objective To study the expression and roles of miR-31-5p in acute myeloid leukemia (AML).Methods miR-31-5p in AML patients were evaluated by real-time PCR;THP-1 cells were transfected with the miR-31-5p mimic and control, respectively.The effects of over-expression of miR-31-5p were examined by CCK-8 and FACS analysis;Dual-luciferase and Western blot were performed to detect target gene HuR expression.The effects of knock-down of HUR were also examined by CCK-8 and FACS analysis.Results miR-31-5p was down-regulated in AML patients compared to the normal control.Over-expression of miR-31-5p in THP-1 cells reduces cell proliferation and accelerates monocytic differentiation.miR-31-5p could target HuR, and knock-down of HuR inhibits cell proliferation and attenuates monocytic differentiation in THP-1 cells.Conclusions miR-31-5p may regulate AML cell proliferation and monocytic differentiation by targeting HuR.
