Objective To investigate the effect of cisplatin on proliferation and invasion of colorectal cancer cell line SW480. Methods SW480 cells were used as the research object, and untreated SW480 cells were used as the control group. Different concentrations of cisplatin was given at different times to intervene. The MTT, Transwell chamber and phos-phate determination methods were used to detect proliferation, invasion and Na+-K+-ATPase activity expression level in SW480 cells. Results The physiological concentration of cisplatin (70 μmol/L) inhibited the proliferation of SW480 cells at 48 h. There was no significant difference in the inhibition rate at 48 h compared with 72 h and 96 h. Treatment with 70 μmol/L cisplatin for 48 h reduced the number of cells through Matrigel membrane matrix. The Na+-K+-ATPase activity was significantly increased in 35, 70 and 140 μmol/L cells after treatment with 17.5, 35, 70 and 140 μmol/L of cisplatin in SW480 cells for 48 h, and Na+-K+-ATPase reached the highest level at 70 μmol/L of cisplatin. Conclusion The decreased activity of Na+-K+-ATPase may lead to the attenuation in proliferation and invasion of colorectal cancer cells, which may be associated with cisplatin resistance in colorectal cancer cell SW480.

Protein fingerprinting technology(PFT) is a novel technology for laboratory diagnosis developed in recent five years.It has advantages of simple operation,testing quickly,high sensitivity and specificity.It is a revolutional progress for laboratory diagnosis.The application of PFT in medical field is mainly for the detection of diseases.The sensitivity and specificity in cancer detection are about 80%.Immunomic mass spectrometry(IMS) is a novel technology using the combined group antibodies for capture multi biomarkers and applying mass spectrometry to precisely analyze the modification or isoforms of the biomarker in single platform,whereas traditional assay could not be able to identify the variation of biomarkers.PFT and IMS have significantly influenced in cancer early detection,especially to evaluate cancers which did not express traditional tumor markers like AFP,CEA,etc.PFT and IMS have characteristics of early detection in the molecular and gene level.PFT and IMS are diagnostic technologies with bright future and potential applications.

The clinical supervision of counseling and psychotherapy have a closely connection with clinical employment.Leading the way in clinical supervision,many clinical supervision models has been extrapolated by theories of various psychotherapy,relating to psychoanalysis theory,person-centered approach theory,cognitive and behavior psychotherapy theory,system theory,structuralism theory,and so on.Recently,especial,different clinical supervision models have to expand beyond psychotherapy,such as developmental model of supervision and society role model of supervision.The study has summarized clinical supervision models of the field,in order to offer literature index and concept frame.

Objective To investigate the value of multi-slice spiral CT(MSCT)in diagnosis of the causes of intestinal obstruction.Methods 49 cases of intestinal obstruction confirmed by surgery or clinical diagnosis underwent abdominal MSCT plain and enhanced scanning,three-dimensional post-processing reconstruction was done in 5 cases.CT features were analysed blindly by two senior radiologists,including the thickness,density and degree of enhancement of intestinal walls at the "transition zone" area of intestine and surrounding mesenteric structure.The causes of intestinal obstruction were analysed in combination with clinical history of the patients.Results The causes of intestinal obstruction were suggested by MSCT in 46 cases(94%),including intestinal adhesion in 13 cases,tumor in 11,hernia in 4,ischemic bowel disease in 4,gallstone in 2,gastrolith in 2,Bezoar in 4.paralytic ileus in 3 and appendiceal abscess in 3.Three cases were misdiagnosed.Conclusion MSCT is of significant clinical value in diagnosis of intestinal obstruction,which should be used as the first means in clinic practice.

Intracerebral hemorrhage (ICH) is a common nervous system disease, its mortality and disability are very high. However, the mechanisms of brain injury after ICH have not yet been fully explained. "[he latest studies have suggested that iron overloading plays an important role in the brain injury after ICH. This article reviews the advances in research on the distribution and function of iron in the brain, the mechanisms of brain injury caused by iron overloading after ICH as well as the use of iron chelator.

Objective To investigate the influence of laparoscopic cholecystectomy (LC)versus open cholecystectomy (OC)on postopera-tive systemic infection and immune response in patients with acute cholecystitis complicated by choleperitonitis.Methods A prospective randomized controlled trial was performed for 45 patients who had a definite diagnosis of acute calculous cholecystitis complicated by cho-leperitonitis in Shanghai Liqun Hospital from January 2014 to June 2016.According to surgical procedures,the patients were randomized in-to LC group (23 patients)and OC group (22 patients).The length of hospital stay,postoperative complications,and deaths were evaluated in both groups.Blood samples were collected from all patients before surgery and at 1,3,and 6 days after surgery to compare the changes in neutrophil count,serum levels of C -reactive protein (CRP)and interleukin -6 (IL -6),and erythrocyte sedimentation rate (ESR),as well as the incidence of endotoxemia.The t -test was used for comparison of continuous data between groups,and the chi -square test was used for comparison of categorical data between groups.Results The LC group had a significantly shorter length of hospital stay than the OC group (5.4 ±2.7 d vs 10.2 ±3.5 d,t = -5.46,P <0.001).One patient (4.3%)in the LC group and 6 (27.3%)in the OC group ex-perienced peritoneal abscess after surgery,and there was a significant difference in the incidence rate of complications between the two groups (χ2 =4.77,P =0.03).In all patients,the mortality rate was 17.8% (8 /45),with 1 (4.3%)in the LC group and 7 (31.8%)in the OC group,and there was a significant difference between the two groups (χ2 =5.16,P =0.02).Of all patients in the OC group,4 died of peritoneal abscess,1 died of pulmonary embolism,and 1 died of myocardial infarction;of all patients in the LC group,1 died of my-ocardial infarction.There were no significant differences in inflammatory markers before surgery between the two groups.At 1,3,and 6 days after surgery,the LC group had significantly lower neutrophil count,serum levels of CRP and IL -6,and ESR (except at 1 day after surger-y)than the OC group (all P <0.05).Furthermore,the OC group had a significantly higher concentration of endotoxin than the LC group (P <0.05),but the level of endotoxin returned to normal at 2 days after surgery in both groups.Conclusion Compared with OC,LC can reduce the probability of endotoxemia,help with the establishment of immunological defense,and reduce the risk of postoperative infection.
