Objective To explore core competency of nursing students during internship in western China,and to provide reference for the nursing education.Methods 380 nursing students during internship were investigated with Competency Inventory for Registered Nurse (CIRN).Results The total score of core competency of nursing students was (136.40±31.99) points,weighted mean scores of eight dimensions was (2.36±0.51)points;the highest mean score was the dimension of legal and ethical practice (2.88±0.57)points,and the lowest mean score was the dimension of critical thinking (1.91±0.52)points.There was significant difference of core competency in students with different education background and with varied firstchoice profession.Conclusions The core competence of nursing students during internship remains at lower middle level.The nursing educators should shift their concept of nursing education to the new mode of professional competence orientation.

Objective To report a simple, minimally invasive method of palliative drainage for symptomatic malignant ascites, in order to avoid repeated trips to hospital for paracentesis.Methods Since July 2000, 57 patients with symptomatic, large volume refractory ascites underwent percutaneous placement of Arrow catheter through a modified Seldinger technique with straight coaxial needles. There were 41 men and 16 women Age ranged from 34～83 years old with an average of 63, including 28 patients of primary liver cancer, 17 metastatic liver cancer, 5 Budd Charri syndrom, 4 pancreatic cancer, 2 peritoneal metastasis of gastric cancer and one with overian cancer. All patients underwent ascites drainage with Arrow catheter accompanied by medical treatment. Results The Arrow catheter had detained for 1 19 days with an average of 5.7 days. Draining amount of ascites was 800 12 000 ml, average 7 200 ml. No complication of sepsis, peritonitis, or significant hypotension after catheter placement but with 7 cases of persistent leakage around the catheter, 2 accidentally detached cathere, 2 cases of unfluent drainage and one case of inferior epigastric blood vessel injury.Conclusions Percutaneous placement of Arrow catheter using a modified Seldinger technique with coaxial needles is a safe, simple, and effective method for palliative drainage of malignant ascites that improves patients life quality.

Tumor invasion model is an important tool to study the mechanisms of tumor mvasion and to evaluate prevention and treatment of cancer.Compared to the in vitro model,in vivo model can simulate the tumor microenvironment and tumor mvasion biological behaviour better.Morphological observation and invasion-related protein detection can be used to evaluate the animal invasion model,which are widely used in basic and clinical research now.

Objective To investigate the NAT(nucleic acid amplification technique)-HBV/HCV results among single ALT(+)blood donors,in order to provide theoretical basis of optimizing strategy for blood screening.Methods A total of 28 800 samples,from December 2006 to December 2007,were studied retrospectively.ALT was tested by rate method.HBV-DNA and HCV-RNA in single ALT(+) samples were detected via NAT-HBV/HCV.The relationship between positive ALT values and ELSIA-HBV/HCV OD values was analyzed.Results A total of 2 516 ALT(+) cases were found in 28 800 samples.Of these ALT(+)cases,8 positive cases were found via NAT-HBV/HCV,including 5 HBV-DNA(+) and 3 HCV-RNA(+) cases.The positive rates of NAT-HBV/HCV for the donors with ALT values ≤80 U/L were significant lower than those with ALT values≥81 U/L(P

Objective To explore the efficacy of transurethral nephroscopic pneumatic lithotripsy combined with ultrasound lithotripsy for bladder calculus.MethodsBy using transurethral F20.8 nephroscope and EMS LithoCaster,we performed transurethral nephroscopic pneumatic lithotripsy and ultrasound lithotripsy on 69 patients with bladder calculus(63 men and 6 women)between October 2005 and May 2008.The diameter of the calculi was ranged from 1.5 to 6.0 cm.Among the patients,42 had one stone in the bladder,while 27 had multiple calculi.Fifty-five patients were complicated with BPH,14 had neurogenic bladder,and 4 showed bladder diverticulum with stones in situ.Pneumatic frequency was set at 8-12 Hz,and ultrasonic energy was 50%-60%.For the patients with BPH electrovaporization ablation was plused.ResultsAmong the 69 patients,68 were cured in one session.The mean operation time was 25 minutes(15 to 40 minutes).One patient was converted to open surgery because of rupture of the bladder during the procedure.No patient had urethral stricture,infection,or massive hemorrhage during the operation.Follow-up was available in 68 patients for 6 to 10 months(mean,9 months).During the period,no recurrent calculi was found by ultrasonography and X-ray.ConclusionTransurethral nephroscopic pneumatic lithotripsy combined with ultrasound lithotripsy is effective for bladder calculus.

Objective To investigate the significance of enzyme-linked immunosorbent assay (ELISA) in cross-match test of donor-recipient before organ transplantation.Methods HLA glycoproteins were prepared by solubilizing the lymphocytes of donor with a non-ionic detergent, and bond to the monoclonal antibody specific for HLA class Ⅰ or Ⅱ immobilized in the ELISA tray. ELISA with addition of recipients' serum and complement-dependent cytotoxicity (CDC) were compared.Results Cross-match test was performed by two methods for lymphocytes of 40 donors and sera of 72 recipients. All samples were successfully tested. The results of one pair of donor-recipient cross-match test by two methods were different.Conclusion ELISA for cross-match test is simple, convenient and time-saving, but more sensitive and specific than CDC.

Objective To investigate the antitumor mechanism of sodium arsenite on human gastric carcinoma cell line SGC-7901 in vitro. Methods MTT assay, light microscopy, electron microscopy, flow cytometry, and immunocytochemical staining were used to analyze the effect of sodium arsenite on biologic behavior of SGC-7901 cells. Results Sodium arsenite (2.50 ～ 40.00 ?mol/L) could inhibit the growth of gastric carcinoma cells, it depended on the duxation and concentration, and its 50% inhibitory concentration(IC50) was 8.69 ?mol/L after 72 hours' treatment. SGC-7901 cells were arrested significantly in G2/M phase treated with sodium arsenite for 48 and 72 hours. SGC-7901 cells presented typical morphologic feature of apoptosis and necrosis after exposure to sodium arsenite. Sodium arsenite up-regulated Caspase-3 protein expression in SGC-7901. Conclusion Sodium arsenite could obviously inhibit the proliferation of SGC-7901 cells, induce cell cycle arrest and apoptosis and necrosis of the cells. its mechanism is possibly associated with inhibition of elimination of ROS and the up-regulated expression of Caspase-3 protein.

Objective To explore the surgical reconstructive procedures of adult-to-adult living donor liver transplantation (LDLT).Methods Two patients with end-stage liver disease were successfully subjected to adult-to-adult LDLT using dual grafts in our division. One patient’s donors were left lobe and left lobe from his two old sisters, respectively. The other graft was right lobe from his 56 years-old mother and left lobe separated from a cadaveric organ donor.Results Both recipients and three donors display good graft function and normal triangular shape regeneration of their liver grafts after liver transplantation. There was neither mortality nor serious complications in the donors. Conclusion The critical issue of LDLT is donor morbidity. Dual grafts from two living donors can help to alleviate the problem of small-for-size grafts and yet secure the safety of the donor. But the complicated surgical techniques give a great challenge for liver transplant surgeons.

Objective To study the curative effect of Bairui capsule combined with azithromycin in treatment of children with mycoplasmal pneumonia and its effect on serum high sensitive C-reactive protein, eosinophil, soluble interleukin-2.Methods 86 patients with mycoplasma pneumonia were enrolled from August 2015 to July 2016 in our hospital.According to the order of admission, the patients were divided into observation group and control group.The control group was treated with azithromycin , and the observation group was treated with Bairui capsule and azithromycin.Clinical efficacy,symptoms and signs of disappearance of time, CRP, EC, SIL-2R and adverse reaction rate were compared between the two groups.Results The total effective rate in the observation group was significantly higher than the control group [90.70% (39/43) vs 67.44% (29/43)](P<0.05).The time of disappearance of lung rales, the disappearance time of cough, the time of fever and the recovery time of X -ray in the observation group were significantly shorter than the control group (P<0.05).The levels of serum hs-CRP, EC and SIL-2R in the observation group were lower than the control group (P<0.05) .There was no significant difference in adverse reaction rate between observation group and control group.Conclusion Bai Rui capsule combined with azithromycin in children with mycoplasma pneumonia can effectively reduce the serum hs-CRP, EC, SIL-2R levels, clinical efficacy is good, low adverse reaction rate.

Objective To explore the expression of interleukin 13(IL-13) mRNA in peripheral blood mononuclear cells (PBMCs) and its association with serum C-reaction protein(CRP) in patients with ulcerative colitis(UC). Methods IL-13 mRNA expression in PBMCs was detected by RT-PCR in patients with UC(21 cases of active UC and 10 cases of quiescent UC)and 20 healthy subjects. At the same time, the serum level of CRP was detected by ELISA. Results The expression level of IL-13 mRNA in PBMCs of patients with active UC was significantly lower than that in PBMCs of patients with quiescent UC and healthy subjects (6.45?1.23 vs 14.72?2.12 or 15.17?2.38,P0.05). The expression level of IL-13 mRNA in PBMCs of active UC patients was negative correlation with serum level of CRP (r=-0.589,P
