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 effect of continued nursing education manual on surgical nursing education.Methods A continued nursing education manual was designed and applied to surgical nursing education.The effects were assessed by comparing the nursing training results before and after intervention by the manual in terms of nursing theory test,nursing techniques test.Results After the application of manual,the training coverage rate increased from 94.59%to 100.00%(P<0.05),the pass rate of theory test increased from 87.57%to 94.21%(P<0.05),and the pass rate of nursing skills test increased from 90.27%to 96.14%(P<0.05). Conclusion The continued nursing education manual is effective in improving the educational effect of surgical nursing.

ObjectiveTo discuss the incidence of negative emotion and behavioral problems between left-behind and non-left-behind children in rural areas during hospitalization. Methods175 participants included 90 cases of non-left-behind children patients and 85 left-behind children patients.The negative emotion and behavioral problems of all children were recorded and compared. ResultsCompared with the non-left-behind children patients,left-behind children manifested negative emotions such as anger,anxiety,depression and fear,more probability and incidence of behavioral problems such as dysphonia,special learning disabilities,sleep disorders,twitch disease,multiple tourtte's syndrome,attention deficit disorder,enuresis sickness and so on.There was significant differences between the two groups. ConclusionsCompared with the non-left-behind children,left-behind children patients are more likely to have negative emotion and behavioral prob-lems,it may have lasting influence on children and eventually influence the development of the physical and mental health,cause learning and adaptation difficulties.So more care and attention should be given to left-behind children,and given timely discovery and timely treatment of negative emotions and behavioral problems.

Objective To investigate the clinical efficacy and safety of topical corticosteroids as adjunctive plan in the therapy of bacterial corneal ulcers (BCU).Methods 62 eligible patients with confirmed BCU were screened and divided into 2 groups randomly.Both groups were treated with topical tobramycin for 3 weeks,the observation group received topical tobramycin for at least 48 hours and then treated with 0.02％ fluorometholone for 3 weeks,and decrement setp by step.Best spectacle corrected visual acuity(BSCVA),fluctuation of intraocular pressure (IOP) before and after therapy,time to corneal reepithelialization and clarity,severe adverse event were observed.Results After 3 weeks,BSCVA of both groups increased compared to their baselines,however,no significant difference between the two groups.Patients whose IOP exceed 21mm Hg in the control group was statistically more than that in the observation group(x2 =7.272,P ＜ 0.05).Follow up for 3 months,increasing of BSCVA in the observationgroup was significantly higher than the control group(t =2.388,P ＜ 0.05) ;and lOP of both two groups almost recuperated to baselines.Although the time to corneal reepithelialization of the control group (11.3 ± 4.5) d was shorter than observation group [(14.7 ± 5.2) d] (t =2.707,P ＜ 0.05),the recovery of corneal clarity in observation group was superior to control group (x2 =8.207,P ＜ 0.05).In addition,no severe adverse events were observed during this period.Conclusion Although prolong the healing time of corneal epithelium,corticosteroids as an adjunctive plan in the therapy of BCU may reduce immune-mediated damage,decrease scarring,control IOP fluctuation and improve BSCVA,but with no safety concerns.

BACKGROUND:Bio-Gide col agen membranes show a good biocompatibility with stem cells. But the research on the osteogenetic differentiation of bone marrow mesenchymal stem cells cultured on the Bio-Gide col agen membranes is rarely reported. OBJECTIVE:To observe the effect of Bio-Gide col agen membranes on the proliferation and the osteogenetic differentiation of bone marrow mesenchymal stem cells. METHODS:Bone marrow mesenchymal stem cells from rabbits were isolated and cultured by using the whole bone marrow adherence method in vitro. Passage 3 bone marrow mesenchymal stem cells were selected and seeded on the Bio-Gide col agen membrane pretreated petri dish (experimental group) and simple petri dish (control group). The proliferation of bone marrow mesenchymal stem cells was detected by cellCounting Kit-8 at 1, 4, 7, 14 days. The supernatant of the cells cultured in osteogenic differentiation medium were col ected to detect the activity of alkaline phosphatase at 1, 4, 7, 14 days. RESULTS AND CONCLUSION:The number of bone marrow mesenchymal stem cells in the two groups was increased with the increasing time, and the control group had more cells than the experimental group at 7 days (P<0.05). There was no significant difference between the two groups at other time points. The alkaline phosphatase activity was increased with the increasing culture time, and the experimental group had a higher activity than the control group at 14 days (P<0.05). There was no significant difference between the two groups at other time points. Experimental findings indicate that Bio-Gide col agen membranes can promote the proliferation and the osteogenetic differentiation of bone marrow mesenchymal stem cells.
