ObjectiveTo investigate the complication and nursing of intestines nutrition in critical patients after operation. MethodsThe clinical states of 40 patients after operation and being brought to ICU were analyzed.ResultsPatients accepting intestines nutrition presented high incidence of gastrointestinal complications. ConclusionIt is important to pay attention to prevent gastrointestinal complications in patients accepting intestines nutrition early postoperation.

Objective To investigate the effects of sodium butyrate (SB) on fetal gastric epithelial cells (GECs) in vitro damaged by N-methyl-N’-nitro-N-nitrosoguanidine (MNNG). Methods The fetal gastric epithelial cells were isolated, cultured and identified. Then the cells of the second generation were cocultured with 10 -5 mol/L, 10 -6 mol/L, 10 -7 mol/L SB for 4 h, then added with 10 -5 mol/L MNNG culturing for another 24 h. After the treated cells were finally cultured in normal culture medium for 40 d, the unscheduled DNA synthesis (UDS), lipid peroxidation (LPO) and ras p21 were detected. The cells were only cultured with 10 -5 mol/L MNNG served as negative control and without MNNG or SB as normal control. Results The level of UDS, the contents of lipid peroxidation products and the concentrations of ras p21 in GECs treated with 10 -5 mol/L and 10 -6 mol/L SB decreased obviously, and had significant differences with that of GECs treated without SB. Conclusion SB can effectively prevent the damage of GECs induced from MNNG.

Objective:To construct eukaryotic expressing vector of the full length coding sequence of Bad gene and to express the gene in the basal cell carcinima A431 cells.Methods:Bad gene was amplified from Hela cell line by RT-PCR and the fragment of the cDNA was cloned into eukaryotic expressing vector pcDNA3.1-myc by ligating the fragment into XhoI and EcoRI site.The recombinant plasmid pcDNA3.1-myc-Bad was identified by DNA sequencing and restriction enzyme analysis.The gene transfection mediated by lipofectin was used to introduce the eukaryotic expressing vector of pcDNA3.1-myc-Bad into human basal cell carcinima A431 cells. After selection with G418, resistant colonies were obtained.Trasfection efficiency was identified by Western blot and SABC-FITC assay.Cell proliferation was examined by cell counting and colonogenic assay after transfection.Results:A 500 bp DNA fragment was amplified with RT-PCR.Sequence and restriction enzyme analysis showed that the recombinant plasmid pcDNA3.1-myc-Bad was constructed successfully.In human basal cell carcinima cell line A431 Bad gene was expressed.The cell proliferation was inhibited by 62.6% and colonogenesis by 39.9% by the transfection of the gene.Conclusion: Human Bad gene was successfully cloned.Transfection of basal cell carcinoma cells with the gene may inhibit the cell proliferation and colonogenesis.

Objective To establish the relationship of serum TNF-? and IL-6 contents with myocardial cell apoptosis in the chronic heart failure (CHF)rats,and to explore the therapeutic mechanism of Anxin Granules (AXG)in treating CHF.Methods Fifty female SD rats were randomly divided into five groups:normal control group (A),model group (B),captopril group(C),low-dosage AXG group (D)and high-dosage AXG group (E).CHF models were established by intraperitoneal injection of small-dose of adriamycin,once per week for continuous 6 weeks.Meanwhile,group C was given captopril injection (6.25mgkg-1d-1),and groups D and E received gastric gavage of low-dosage AXG (0.8 gkg-1d-1)and high-dosage AXG (1.6gkg-1d-1)respectively.After 6 weeks of modeling,serum levels of TNF-? and IL-6 of different groups were tested by ELISA,the apoptosis of myocardial cells was tested by TUNEL,and then the apoptosis index(AI)was counted.Results Serum levels of TNF-? and IL-6 were increased in the model group (P

Objective To explore effective methods of diagnosis and treatment for delayed rupture of the spleen (DRS) through retrospective analysis of 32 cases. Methods A retrospective study was done in 32 cases with DRS. The effects of CT, ultrasound and diagnostic peritoneal lavage on diagnosis of DRS was observed and compared. Results Splenectomy was performed in 26 cases, among which one died four days after splenectomy because of complicated brain injury and six given conservative treatment under continuous monitoring discharged. The mean hospitalization duration was 18.5 days. Conclusions Diagnostic peritoneal lavage can improve the positive rate of peritoneal puncture. Ultrasound is an important method for diagnosing DRS and closely monitoring the patients receiving conservative treatment.

Purpose:To study the changes of t-PA ?u-PA expression and fibrinolysis molecular mark ers in patients with gastric or intestinal cancer in order to elucidate their cl inical significance. Methods:The plasma levels of t-PA ?u-PA ?u-PAR and PAP were measured by ELISA . Gen e transcription of t-PA?u-PA mRNA were detected by Real-time RT-PCR. Results:The plasma levels of u-PA?u-PAR and PAP were elevated in gastric or intestina l cancer patients ,while u-PA was markedly elevated in patients with local infi ltration?lymph node involvement or distal metastasis. u-PA mRNA was higher and t-PA was lower in gastric or intestinal cancer compared to normal tissue. Conclusions:Hyperfibrinolysis was an important factor related with m etastasis potential of gastric or intestinal cancer. t-PA may be a character of well differentiated tissue.

Objective To investigate doctor-patient communication skills status and the influencing factors so as to pu forward to develop the proposal.Methods We selected undergraduate students in fourth grade which participated in the 2012 Shanghai Jiaotong University School of Medicine OSCE examinations before practice of clinical medicine by cluster sampling 1 and we selected four western and chinese medicine hospitals randomly sample 2,which are three level of first-class hospitals in Shanghai.We design the questionnaire and observe sampling with the SEGUE framework.Application of SPSS 13.0 data for statistical analysis,descriptive statistics analysis,u test,t test,ANOVA,rank sum test and correlation analysis method.Results The test with SEGUE framework shows that the scores of samplingl were 12.54 points(out of 24),the score rate is low which was 52.25％,and in the score rate of the dimensions,the end of inquiry dimension is 4％ which is the lowest.There are significant statistical differences between different groups of influencing factors such as Medical occupation interest score and so on.There is no statistically significant difference between the SEGUE score of traditional Chinese medicine and western medicine clinical Intern.The communication skills of western medical students are higher.Doctor-patient communication skills related factors such as recognition of the importance of doctor-patient communication skills and other groups are statistically significant,the correlation coefficients are very small which is between 0.1 and 0.3.Conclusion The overall level of doctor-patient communication skills on clinical internship are not high,through the guidance and training on the occupation interest of medical students,we can strengthen the recognition of the importance of doctor-patient communication skills,so that we will improve the doctor-patient communication skills for the medical students.SEGUE framework should be used to routine medical students communication skills evaluation.
