A clone system designated SAC was established from a SRS-82 mouse ascitic turnout cell line by using limited dilution method. Clones SAC-ⅡB_2, SAC-ⅡB_3 of this system were found to be different in their morphology, growth pattern, karyotypes and tumorigenicity from their parent cell line. Both the two clones and their parent cell line were X-C assay positive, and type A and type C virus particles were found in the cytoplasm and cell surface of these cells electronmicroscopically. Cell surface markers(ALS, Thy, SmIg G) of these two clones and their parent cell line were investigated by ABC immunohistochemical method and immunofluorescent staining technique, the results of which indicate that all of them belong to T cell origin.

Objective To investigate the effects of combined treatment of suberoylanilide hydroxamic acid(SAHA)and TNF?related apoptosis inducing ligand(TRAIL)on proliferation and morphology change of triple?negative breast cancer cell MDA?MB?231. Methods The effects of combination treatment of SAHA and TRAIL on proliferation and morphology change of MDA?MB?231 cells were monitored by RTCA. Morphology changes of MDA?MB?231 cells by different treatment factors were observed through time?lapse live cell imaging acquisition. Results Real?time cell proliferation assays showed that a synergistic effect were found when MDA?MB?231 cells were treated with combination of SAHA and TRAIL , and reached the best effect with 5μmol/L SAHA and 50 ng/mL TRAIL. The results of time?lapse live cell imaging acquisition showed that the growth inhibition of MDA?MB?231 cells with combined treatment of SAHA and TRAIL were more obvious than that with treatment of SAHA or TRAIL alone. Conclusion The combined treatment of SAHA and TRAIL induces a synergistic effect on growth inhibition in triple?negative breast cancer cell line MDA?MB?231.

Objective To investigate the physical and mental health of Shandong medical personnel.Methods 3200 medical personnel were randomly selected from hospitals of Shandong province,selfhealth,depression and sense of work stress were measured and analyzed statistically.Results 36.3％ of medical staff was in depression state,and even about 22.5％ of the subjects was in moderate or severe depression state.Male and female medical staff showed no difference in sense of work pressure.Senior medical staff showed higher working pressure than middle-class,junior-class and low-level medical personnel,but middleclass,junior medical staff and low-level medical staff showed no significant difference.In the aspect of self-health status,male and female medical personnel showed no significant differences,senior,middle-class and junior-class medical staff reported worse self-health status than low-level medical personnel.Conclusions Managers should pay attention to physical and mental health of medical personnel,adopt pertinent measures to reduce their mental pressure in order to promote their physical and mental health.

Doctor-patient relationship is a special relationship between people in special circumstances during a special peri -od, which is directly related to the harmony and stability of society as well as people's quality of life.Values are the fundamental views of people, including the understanding of the nature , composition and standards of values .Doctors and patients are consistent in goals , interests and ideals , having the same objectives to overcome diseases , promote health , and prolong lives .They are essentially unified in values.However, there are some inharmonious phenomena in the relationship between doctors and patients .Efforts should be made to improve the present doctor-patient relationship by the whole society besides doctors and patients , aiming to establish a harmonious doctor-patient relationship of mutual respect , mutual trust , mutual tolerance and mutual cooperation on the basis of common values .

Objective To investigate the clinical effect of Shufeng Tongqiao,Yifei Jianpi therapy on persis-tent allergic rhinitis.Methods From January 2014 to February 2015,80 patients with allergic rhinitis in our hospital were chosen.Using random number table,they were randomly divided into control group and treatment group.The con-trol group was given western medicine,the treatment group was given self designed formula on the basis of the control group.The clinical symptoms,the efficacy and related indicators of the two groups before and after treatment were compared.Results After treatment for 3 months and 1 year,the IgE test results in the treatment and control groups were significantly lower than before treatment(t =13.93,14.45,12.11,7.46,all P <0.05),the IgE test results after 1 year of treatment in the treatment group was significantly lower than the control group (t =-4.59,P <0.05).IgE test results in the control group after one year of treatment was significantly higher than treatment for 3 months (t =-2.61,P <0.05 ).The total effective rate of the treatment group was 87.5%,which was significantly higher than 70.0% of the control group(P <0.05 ).Conclusion Shufeng Tongqiao,Yifei Jianpi method in the treatment of persistent allergic rhinitis has significant clinical effect,it can effectively alleviate rhinitis symptoms,stabilize serum IgE levels.

Mounting evidences suggest that the ATRX (α-thalassaemia/mental retardation syndrome X-linked) and DAXX (death-domain associated protein) which encode 2 subunits of a chromatin remodelling complex required for H3.3 incorporation at pericentric heterochromatin and telomeres,and multiple endocrine neoplasia type 1 (MEN-1) genes are significantly mutated in most patients with pancreatic neuroendocrine tumors (pNETs),as are genes encoding key molecules of the mammalian target of rapamycin (mTOR) signaling pathway.These mutated genes promote deregulation of epigenetic processes such as chromatin remodeling,histone modification and activation of alternative lengthening of telomeres,and thus combined alteration of these genes may contribute to drive tumorigenesis and metastasis of pNETs which are characterized by complex patterns of phenotypes.These findings may have great significance in the diagnosis and treatment of pNETs and predicting the prognosis,as well as providing clinical implications for targeted cancer therapy.

Belief in and rejection of a relationship of occlusion and temporomandibular joint (TMJ)condyle-fossa position with normal and abnormal function are still contentious issues.Clinical opinions can be strong,but support in most published data (mostly univariate)is problematic.Distribution overlap,low sensitivity and specificity are a common basis to reject any useful prediction value.Notwithstanding,a relationship of form with function is a basic tenet of biology.These are multifactor problems,but the questions mostly have not been analysed as such.This review moves the question forward by focusing on TMjoint anatomic organisation as the multifactor system it is expected to be in a closed system like a synovial joint.Multifactor analysis allows the data to speak for itself and reduces bias.Classification tree analysis revealed useful prediction values and usable clinical models which are illustrated,backed up by stepwise logistic regression.Explained vari-ance,R2 ,predicting normals from pooled TMJ patients was 32.6%,sensitivity 67.9%,specificity 85.7%;37% versus disc displacement with reduction;and 28.8% versus disc displacement without reduction.Significant osseous organisational differences between TMjoints with clicking and locking suggest that this is not necessarily a single disease continuum.However,a subset of joints with clicking contained char-acteristics of joints with locking that might contribute to symptom progression versus resistance.Moderately strong models confirm there is a relationship between TMJ osseous organisation and function,but it should not be overstated.More than one model of normals and of TMde-rangement organisation is revealed.The implications to clinical decision-making are discussed.

Objective To improve the understanding of small cell carcinoma of the urinary bladder. Methods The pathological and clinical data of 6 small cell carcinoma cases (4 men and 6 women, mean age of 51 years) were analyzed.Of them 2 cases had components of transitional cell carcinoma or adenocarcinoma.Two cases underwent partial cystectomy,and 4 cases,cystectomy.After operation,5 of them underwent 2～6 courses of chemotherapy. Results All the 6 cases were followed-up for 12～60 months,and they all died of tumor relapse.Their average survival time was 28 months. Conclusions Small cell carcinoma of urinary bladder accounts for 0.44% of the primary malignant tumor of urinary bladder.It has high malignancy and easily metastasizes to lymph nodes,liver and bones,thus the prognosis is bad.Radical cystectomy in combination with systemic chemotherapy has better efficacy.
