Cryoablation,a kind of physical ablation for tumor treatment,is minimally invasive,safe and effective.Studies suggest that cryoablation can not only kill tumor cells directly,but also the anti-tumor immune response triggered by cryoablation plays an important role in inhibiting the growth of local tumors and eliminating the residual tumor cells.

Objective To investigative the relationship of personality and coping style with subjective well-being in nurses.Methods 140 nurses were invited randomly to answer the questionnaires.123 questionnaires out of 140 were selected,with 17 papers excluded because of un-complete answer.Personality,coping style and subjective well-being were respectively estimated with Eysenck Personality Questionnaire(EPQ),Simplified Coping Style Questionnaire(SCSQ) and General Well-Being Scale(GWB).The resuits were compared with the national norm.Correlation analysis was performed in term of the correlation of personality and coping style with subjective well-being.Results Subjective well-being of nurses was associated with personality and coping style.Conclusions Personality and coping style can predict subjective well-being.The research can provide theoretical basis for psychological care to the nurse group.

Amyloid beta-peptides ( Aβ) is the key pathological feature of Alzheimer’s Disease (AD). Various factors contrib-ute to the accumulations of Aβ in the brains of patients. Among them, blood-brain barrier ( BBB) plays a crucial role in trans-porting Aβ between the brain and the bloodstream while this transfer function is mediated by the receptor of Aβon BBB. The abnormality of Aβ transport and related receptor expression can be detected in the brains of patients with AD, resulting in an un-usual increase in Aβlevels unusually increased . This review e-laborates the structure and function of BBB, the transport of Aβand the expression and transport mechanism of the related recep-tor, as well as summarizes the possible clearance strategy of Aβacross the BBB.

Objective To study the application of the linear sampling method(LSM) in 2D electromagnetic inverse scattering imaging and to mainly discuss the imaging quality of LSM with partial-view data.Methods Get the norm of solution vector to the equivalent integral equation using numerical calculation in every sampling point at imaging region,and represent the norm with gray to reconstruct the scattering shape.Results Under all incident angles [0,360?] and all observation angles [0,360?],the imaging quality of the far-field pattern of scattering wave was obtained very well.But when reducing the range of the incident angles and observation angles,the imaging quality declined.Particularly,the imaging quality in the case of both incident angles and observation angles being at the same side of the observed object,were much better than both in opposite sides.Furthermore,the profile of the object was imaged more clearly as its position corresponding to the orientation of the incident/observation angle.Conclusion Although the imaging quality will decline with partial-view data in electromagnetic inverse scattering,the effectiveness of imaging with LSM still deserves attention.

Objective:To observe the accuracy of electronic method(EM), handing method(HM) and X-raying method(X-RM) in measuring root canal working length. Methods:Total 31 root canal in vivo were measured with HM, X-RM and EM(by the electronic apical locators-Root ZX and Raypex-5 respectively), and the data were compared with the actual root canal working lengths which were obtained from the sectional view's constrictions of the extracted teeth by magnifying glass. Results:Accuracy of working length measured by Raypex-5 was 93.55%, Root ZX was 87.10%, HM was 35.48%, and X-RM was 48.39%. Significantly statistical differences (P

Objective To compare the effect of establishment of Coronary angiography model in minipigs with right femoral Judkins catheter and 5F universal catheter .Methods Ninteen minipigs were randomized into two groups with right femoral Judkins catheter (ten minipigs)and 5F universal catheter(nine minipigs). Success rate,operation time,X-ray irradiation time were observed .Results The success rate, operation time ,X-ray irradiation time after Coronary angiography in right femoral Judkins catheter group was 100%,(5.68 ±3.53 ) min,(20.84 ±2.45 ) min,in 5F universal catheter group was 88.8%,(6.98 ± 4.13 )min,(26.23 ±8.45 )min.This difference was signifficant( P <0.01).Conclusion Coronary an-giography in minipigs with right femoral Judkins catheter has the advantage of high success rate , less opera-tion time, X-ray irradiation time , is more suit to coronay anatomy of the minipig .

Objective To establish a method for the content determination of berberine hydrochloride in Xiaoyou Capsules.Method A PR-HPLC method was adopted with a SHIMADZU RP-ODS C18 column as stationary phase and 0.05 mol/L KH2PO4(adjust pH to 3 with H3PO4)-Acetonitrile(70:30)as mobile phase.The detector wavelength was at 265 nm,column temperature was at 40 ℃and the flow rate was 1.0 mL/min.Results Berberine hydrochloride in Xiaoyou capsules showed a good linearity in the range of 0.010 73～0.214 6 ?g.The average recovery was 99.87 %,RSD was 1.43 %.Conclusion The method is simple,reliable,with a good separation,so it can be used for the quality control of Xiaoyou Capsules.

Objective To investigate the clinical typing and staging in diagnosis of Severe Acute Respiratory Syndrome (SARS). Methods Retrospective study was designed to analysis the principal clinical characteristic of SARS and the standard of clinical typing and staging was raised. Comparisons with X-ray in lung, change of lymphocyte subset, PaO_2, SaO_2,and prognosis of disease were performed. Results The standard of SARS clinical typing and staging is four types (light type, ordinary type, heavy type, serious type)and four phases (prodromal period, progres phase, fastigium, recovery phase). The light type is 8/162(4.9%), ordinary type is 69/162 (42.6%), heavy type is 41/162 (25.3%), serious type is (27.2%). Comparisons SARS clinical typing and staging with X-ray in lung, change of lymphocyte subset were found that the more lesion in lung, the lower lymphocyte and its subset, and more serious in clinical typing. Conclusions The standard of clinical typing and staging summarized basic clinical characteristic in SARS, and coincided with progress of SARS. The standard will be help of clinical diagnosis, treatment and judging the prognosis of SARS.

Objective:To explore the relationship of lymphocyte function-associated antigen 3 (LFA-3, CD58) expression in glioma with clinical features and its role in clinical prognosis. Methods:Clinical data and mRNA microarray data of 514 patients with glioma were obtained from The Cancer Genome Atlas and were used to study the expression of LFA-3 (CD58). Cox regression was used to analyze the relationship between CD58 expression and survival of patients with glioma. Multivariate analysis of variance was used to further analyze the relationship of CD58 with age, sex, and pathological grade of glioma. Results:The results of the stratified χ2 test of CD58 expression and tumor grading were shown, considering tumor type, gender and age of diagnosis (all P<0.05). CD58 expression was sig-nificantly correlated with overall survival (OS) and disease-free survival (DFS) of patients with glioma. Patients with high CD58 expres-sion presented short OS and DFS (P<0.0001). Conclusion:CD58 possibly promotes tumorigenesis in gliomas and thus can serve as a potential tumor diagnostic marker and individual therapeutic target.

Objectives To explore the clinical features and diagnosis of LMNA-associated congenital muscular dystrophy. Methods The clinical data from a case of muscular dystrophy caused by LMNA gene mutation were retrospectively analyzed. The related literatures were reviewed. Results A 8-month-old female infant suffered from weakness of raising head, eyelid droop, and motor development retardtion. LMNA gene was sequenced for the infant, her parents and the older sister. Heterozygous mutation of c. 94_96 del AAG (p. K 32 del) was found in the infant leading to the diagnosis of LMNA- associated congenital muscular dystrophy. No mutation was found in the infant’s parents and her older sister. The literature review showed that all ofLMNA- associated congenital muscular dystrophy patients had LMNA gene mutation, more than 80% patients mainly presented with weakness of raising head and may accompany with weakness of proximal limb, motor development retardation, and weakness of axial muscle. Conclusions Mutation analysis of LMNA gene is conducive to the diagnosis of congenital muscular dystrophy.
