Dual material gate SOI MOSFET with asymmetrical halo can suppress short channel effect and increase carriers transport efficiency. The analytical model of its subthreshold drain current is derived based on the explicit solution of two-dimensional Poisson's equation in the depletion region. The model takes into consideration the channel length modulation effect and the contribution of the back channel current component. Its validation is verified by comparision with two dimensional device simulator MEDICI.

Brain ischemia/hypoxia preconditioning(I/HPC) is one kind of endocardial protective phenomenon by organism against blood and oxygen deficit.Researches discovered various proteins such as hypoxic inducible factor-1(HIF-1),heat shock proteins(HSPs),erythropoietin(EPO),Bcl-2 family,calcitoningene related peptide(CGRP) and so on participated in brain I/HPC.This essay explains function and participating I/HPC mechanism of these proteins.

OBJECTIVETo compare the clinical efficacy difference between encircling needling combined with physical factor therapy and simple physical factor therapy for severe pressure sore, and to explore the optimal method for severe pressure sores.

METHODSThirty-four patients with IV-grade pressure sore were randomly divided into an observation group and a control group, 17 cases in each one. Patients in the control group were treated with conventional nursing, ultrasonic wave and short-wave ultraviolet therapy; additionally, the encircling needling was applied in the observation group. All the treatment was given once a day, 5 times a week, and 4-week treatment constituted one session. Totally, two sessions of treatment were performed. Three indices, including the area of pressure sore, 24-h volume of exudates and wound-bed tissue type, were compared between the two groups before and after treatment; the clinical efficacy was evaluated in the two groups.

RESULTSAfter treatment of one session and two sessions, the area of pressure sore, 24-h volume of exudates and wound-bed tissue type were significantly reduced in the two groups (P < 0.01, P < 0.05), which was more obvious in the observation group (all P < 0.05). The total effective rate in the observation group was 76.5% (13/17) after 1 session and 94.1% (16/17) after 2 sessions, which were superior to 35.3% (6/17) after 1 session and 64.7% (11/17) after 2 sessions in the control group (both P < 0.05).

CONCLUSIONEncircling needling combined with physical factor therapy can obviously reduce the pressure sore area and 24-h volume of exudates and improve wound-bed tissue type, which is superior to simple physical factor therapy.

【Objective】To investigate the antianxietic action of Xiaoyao San(XS)and Dan Zhi Xiaoyao San(DZXS).【Methods】 Wistar rats were randomized into 5 groups: model control group,high-and low-dose DZXS groups(14.4?g/kg and 7.2?g/kg respectively),and high-and low-dose XS groups(21.06?g/kg and 10.53g/kg respectively).Social interaction test and open-field test were carried out to observe the antianxietic action of XS and DZXS.Except that the model group was given normal saline,the rats in other groups were given the corresponding drugs according to the experimental design for 14 successive days.After treatment,the activities within 5 min were monitored by two observers and then the mean value were calculated.【Results】High-and low-dose DZXS prolonged rats social interaction time and increased the times of body erection and dressing their hair,and low-dose XS also increased the times of body erection and dressing their hair(P

Objective:To explore the clinical appearance,diagnosis method and curative efficacy of one patient with esophageal teratoma complicated with rupture of esophagus in order to raise the awareness of the clinicians for the disease. Methods:The patient with chest pain after eating was admitted to hospital,and upper gastrointestinal radiography,chest CT and endoscopy were taken,which showed rupture of esophagus.Then an emergency thoracic exploration was performed.A too long cleft and much necrosis were identified,so the repair of esophagus was changed into excision and anastomosis. Results: The operation was successful,and the pathological findings showed the rupture of esophageal teratoma.Follow-up showed no complication till now.Conclusion:Esophageal teratoma complicated with esophageal rupture is rare.Clinicians should improve the understanding and reduce the misdiagnosis rate.

Objective To explore the effects of estrogen and angiotensin Ⅱ receptor 1 inhibitor（saralasin）on cell proliferation,cell cycle and apoptosis in endometrial carcinoma cell line HEC-1A.Methods Immunocytochemical assay was applied to detect the expression of AT1-R,PI3K,p-Akt and ERK protein in HEC-1A cell.The effects of estrogen and saralasin on cell proliferation,cell cycle distribution and apoptosis of HEC-1A cell were detected by MTT assay and fluorescence activated cell sorting technique.The expression of ERK and p-Akt protein in HEC-1A cell treated with estrogen and saralasin were analyzed by Western blot.Results The expression of AT1-R,PI3K,pAkt,and ERK protein was found in HEC-1A cell.Estrogen stimulated the proliferation of HEC-1A cell,decreased G0~G1 phase proportion and increased S phase proportion significantly,minimized the number of apoptotic cells,and up-regulated the expression of ERK protein.Saralasin obviously inhibited the proliferation and induced apoptosis of estrogen induced HEC-1A cell,increased G0~G1 phase proportion and decreased S phase proportion,and down-regulated the expression of ERK protein.Conclusion Estrogen could promote the proliferation of HEC-1A cell through AT1-R.AT1-R inhibitor saralasin could inhibit the proliferation and induce the apoptosis of estrogen induced HEC-1A cell.The down-regulation of ERK protein expression by interrupting the mitogen-activated protein kinase（MAPK）signaling pathway might be involved in the possible mechanism.Thus saralasin could be a valid approach to treat ER-negative endometrial carcinoma.

Objective To compare the diagnostic value of digital breast tomosynthesis (DBT) versus digital mammography (DM) in the evaluation mass like lesions in dense breasts. Methods Eight hundred and fifty eight patients, who had DBT and DM, with breast diseases confirmed by pathology were retrospectively reviewed. The breast density and the imaging features were classified according to the standard of American College of Radiology(2013) and breast imaging reporting and data system (BI?RADS) scores. Six hundred and thirty one patients with mass lesions in dense breasts were chosen to included. All 631 patients had DM of both breasts and DBT of affected breast prior to mastectomy. Pathological results were used as the golden standard. Detection rate and diagnostic accuracy of masses, sensitivity and specificity of diagnosis, false negative and recall rates, the margins and spicules and BI?RADS category were calculated. The detection rate and diagnostic accuracy, the margins and spicules of masses were compared with Chi?square test, the BI?RADS scores were analyzed with rank test. Results With DBT, average detection rate increased from 77.3%(488/631) to 84.3% (532/631), average diagnostic accuracy rate increased from 73.4%(463/631) to 82.3%(519/631),with statistical significant difference between groups (c2=27.191,36.890,P<0.01).Sensitivity for DBT and DM were 68.1%(205/301) and 58.8%(177/301), respectively. Specificity for DBT and DM were 95.2%(314/330)and 86.7%(286/330), respectively. Recall rate for DBT and DM were 3.6%(23/631)and 9.8%(62/631), respectively. One hundred and seventy two cases and 75 cases with circumscribed masses of benign cases were detected by DBT and DM, respectively. One hundred and eighty-two cases and 115 cases with spiculated masses of malignant cases were detected by DBT and DM, respectively, with statistical significant difference between groups (c2=70.471 and 21.707, P<0.01). Of 330 malignant cases, the numbers of BI?RADS category 0, 2, 3, 4A, 4B, 4C, 5 on DM images were 19,4,8,13,52,93,141, respectively, the numbers on DBT images were 3,1,7,5,52,83,179, respectively, with statistical significant difference(Z=-2.235,P=0.025). Of 301 benign cases, the number of BI?RADS category 0, 2, 3, 4A, 4B, 4C, 5 on DM images were 43,10,60,117,58,11,2, respectively, the number on DBT images were 20,4,64,150,55,7,1, respectively, with no statistical significant difference between groups(Z=-1.846,P=0.065). Conclusion DBT significantly improves the detection of mass?like lesions in dense breasts, display of mass margin and architectural distortion of surrounding tissue.
