Analysising of the students' role will contribute to improve the quality of clinical teaching.The core of the students' role is “student”,they are the principal part of the learning activities.At the same time,students have on the shoulders the practice role of clinical nurse.The remarkable thing is that the students have kinds of needs of different levels,they should be regarded as the holistic person who have the individual otherness and commonness and the inimitable value.The characteristic of students can influence their behaviors in clinical activities.

Objective To evaluate the diagnostic value of per perineal high -frequency ultrasound and/or per rectal endoscopic ultrasound in anorectal diseases. Methods 54 patients suffered from anorectul diseases, including 22 patients with anal fistula, 14 patients with perianal abscess, 12 patients with rectal cancer, and 6 patients with perianorectal inflammation, were performed with per perineal high-frequency ultrasound and/or per rectal endoscopic ultrasound examination. The diagnostic results were confirmed by clinical diagnosis, including operative and pathological detection. Results Except for the misdiagnosis of 4 cases of orifice location and 1 case of rectal cancer, all the other cases were correctly diagnosed. Conclusion Combined application of per perineal high-frequency ultrasound and per rectal endoscopic ultrasound examination has great practical value for ascertaining the trend and internal orifice location of anal fistula, location of perianul abscess, the infiltration depth of rectal cancer, and lymph node metastases.

Objective To investigate the immunologic etiology of pregnancy induced hypertention (PIH)by studying the changes of T H1 and T H2 cell ratio in the peripheral blood from patients with severe PIH. Methods We examined the cell percentage of T H1 cell(secreting cytokine IFN ?) and T H2 cell(secreting cytokine IL 4),which were from CD4 positive, by flow cytometry tri stained with PerCP CD4,FITC IFN ? and PE IL 4 monoclonal antibody. The blood samples were from severe PIH patients and normal third trimester patients. Results The percentage of T H1 cell 38.01?9 04% from the peripheral blood of severe PIH partuients was significantly higher than that of the normal partuients of the third trimester 30.26?8.65%, while the percentage of T H2 cell 2.25? 0.61% was much lower P

Objective To explore the role of serum levels of Klotho protein and fibroblast growth factor(FGF)-23 in patients with chronic kidney disease(CKD).Methods A total of 160 patients with CKD were recruited into CKD group in this study,160 healthy controls were selected in the control group from March 2014 to March 2016.Basic clinical data,blood biochemical index,serum level of Klotho protein and FGF-23 were analyzed and compared between the two groups.Results The hemoglobin,serum albumin,blood calcium,glomerular filtration rate,Klotho protein levels in the CKD group were lower than those in the control group,and the serum creatinine,blood urea,blood serum phosphorus and FGF-23 were higher than those in the control group(P<0.05).With the progress of CKD stages,hemoglobin,glomerular filtration rate,Klotho protein levels gradually decreased,serum creatinine,blood urea,blood serum phosphorus,FGF-23 level increased(P<0.05).The levels of FGF-23 were negatively related to hemoglobin,glomerular filtration rate,Klotho(r=-0.584,0.692,-0.724)and were positively correlated to serum creatinine,blood urea,blood serum phosphorus(r=0.814,0.703,0.527).The levels of Klotho protein were positively related to hemoglobin,glomerular filtration rate(r=0.612,0.685),and were negatively correlated to serum creatinine,blood serum phosphorus,blood urea,FGF-23(r=-0.720,-0.690,-0.519,0.724).Conclusion High concentrations of FGF-23 and Klotho protein with low concentration were not only related to calcium phosphate metabolic disorders of patients with CKD,and were also associated with the prognosis of patients with CKD,which might be early biomarkers and predictor in patients with CKD.

Objective To investigate the correlation between umbilical cord blood tire mass measles antibody and maternal measles antibody degrees,in order to evaluate the crowd measles antibody level and provide scientific basis for lasting elimination of measles.Methods Collected 40 cases of healthy maternal venous blood and their paired cord blood,enzyme-linked immunosorbent assay (ELISA) was used for the detection of measles antibody.Results In the 1:200 level,mother blood and umbilical cord blood of measles antibody level were 11.29 ±4.81 and 12.76 ± 5.32,in the 1:800 level were 6.89 ±4.11 and 8.28 ± 4.91,both had correlation (r =0.575,0.618,P ＜0.05).Conclusions Measles antibody titers of maternal venous blood and paired cord blood are highly correlated.The results show that maternal measles antibodies could pass through the placenta to the daughter,and measles antibody titers detected in umbilical cord blood can be used not only to assess the maternal measles antibodies level,but also can be used as a predictor of measles antibody levels for newborns and young children.

The paper described the practice of contingency nursing management for ICU wards in case of power breakdown in the hospital The SICU wards have developed their power failure contingency plan in which the nurses on duty are divided into Group A,B and C according to their positions and qualifications.Respectively,they take charge of patient safety,coordination and command,and medical aid.We also established the procedure of emergency response for these duties.Training and examination familiarize the medical personnel with the procedure and their duties.Four practices proved that the implementation of the plan reduces risks exposure and improves the satisfaction.With the contingency plan,the nurses in ICU can now take care of critical incidents and avoid nursing risks in ICU efficiently.

Objective To investigate the proportion of follicular fluid CD56~+ natural killer (NK) cells to the total lymphocytes and the ac-tivated CD56~+ NK cells to the total CD56~+ NK cells. To provide an evidence for improving the clinical pregnancy rate in in vitro fertilization (IVF) treatment by regulating the function of NK cells. Methods Triple color flow cytometry was used to analyze the proportion of CD56~+ NK cells and activated CD56~+ NK cells in mature follicular fluid. The IVF treatment outcome was closely followed up. The relationship be-tween the proportion of CD56~+ NK cells and activated CD56~+ NK cells and the IVF treatment outcome was analyzed statistically. Results The proportion of CD56~+ NK cells and activated CD56* NK cells in mature follicular fluid of women who got pregnancy by IVF treatment was (15.57±3.10)% and (2.63±0.94)% respectively,while the proportion of the women who didn't get pregnancy was (19.12±5.37)% and (4.06±2.08)% respectively,which was significantly higher than the pregnant group(P< 0.05). Conclusion The women with lower propor-tion of CD56~+ NK cells and activated CD56~+ NK cells in mature follicular fluid of is easier to get pregnancy by IVF. An altered NK cells pro-file in follicular fluid could therefore influence fertility in IVF treatment outcome.

Objective To investigate the pregnancy outcomes of in vitro fertilization (IVF) and embryo transfer (ET) in infertile women with polycystic ovarian syndrome (PCOS).Methods From August 2005 to June 2011,200 IVF-ET cycles performed in women with polycystic ovarian syndrome in Shengjing Hospital and Shenyang 204 Hospital were enrolled in this retrospective study,matched with 400 IVF-ET cycles in infertile women with fallopian tube factors as control group.The incidence of abortion,gestational diabetes mellitus (GDM),hypertensive disorders in pregnancy,preterm birth,small for gestational age infant(SGA),large for gestational age infant (LGA),neonatal asphyxia,neonatal death and deformity was compared between two groups.Results The incidence of spontaneous abortion was 26.0％ (52/200) in PCOS group,which was significantly higher than 10.2％ (41/400) in control group (P ＜ 0.05).The incidence of GDM,hypertensive disorders in pregnancy,preterm birth,cesarean section in PCOS group was 23.6％ (35/148),16.2％ (24/148),17.6％ (26/148),83.1％ (123/148),which were significantly higher than 4.2％ (15/359),6.1％ (22/359),7.8％ (28/359),73.8％ (265/359) in control group (P ＜0.05).The incidence of SGA,LGA,neonatal asphyxia,neonatal death and deformity did not show remarkable difference between two groups,which were 2.7％ (4/148),4.7％ (7/148),5.4％ (8/148),0 in PCOS group and 1.4％ (5/359),2.2％ (8/359),2.8％ (10/359),0 in control group (P ＞0.05).Conclusion IVF-ET is an effective treatment for infertile women with PCOS,however,the incidence of spontaneous aborcion,GDM,hypertensive disorders in pregnancy,preterm birth,cesarean section in PCOS patients was increased.

Objective To determine the bacterial composition and antibacterial resistance in female urinary tract infections (UTI) in China. Methods The disc diffusion test, minimum inhibition concentration (MIC), test or E-test was used to detect the antimicrobial susceptibility in 86 tertiary hospitals in China from June 1, 2006 to May 31, 2007. WHONET 5.4 was applied for data analysis. Results A total of 6071 pathogenic germs were collected from urine cultures of UTI female patients in the surveillance period, which included 5958 bacterial isolates. Escheriehia coll 3529 strains (59. 23% ), Enterococcus spp 938 strains (15.74%) and Klebsiella pneumoniae 394 strains (6.61%) were the most common pathogens. Escherichia coli and Klabsiella pneumoniae had 35.7% and 34. 0% extended spectrum beta-lactamases (ESBL) positive rates, and their resistant rates to quinolones were about 70% and 40%, respectively. Enterococcus faecium was much more resistant to almost all the antibiotics than Enterococcus faecabs. 0. 9% Escherichia faecalis and 3.8% Escheriehia faecium were resistant to vancomycin, whereas 2.7% and 4. 8% were resistant to teieoplanin. Staphylococcus epdermidis was more common in UT1 than Staphylococcus aureus, 79. 1% and 75.0% of the isolates being methiciUin-ressitant Staphylococcus epdermidis(MRSE) or methicillin-ressitant Staphylococcus aureus (MRSA), respectively. No vancomycin intermediate or resistant staphylococcus was detected, but 4. 9% teicoplanin intermediate rate was found in Staphylococcus epdermidis. The resistant rates to quinolones increased with the patient age. Condnsions Bacterial resistance in UTI in Chinese females is a severe problem, which could be resulted from antimierobial irrational use. In the selection of antimicrobial agents in the treatment of UTI, doctors should refer to the results of bacterial resistant surveillance.

Objective To observe the anti-tumor action of Fuzheng Yuliu Tablet(FYT).Methods Mice received subcutaneous injection of S180 into right axilla.Then the tumor-implanted mice were randomized into 6 groups: model group,FYT groups(at the dose of 2.4 and 12.4g/kg respectively),cisplatin group(at the dose of 8?g/d),and cisplatin+FYT groups.The treatment lasted 10 days.The tumor-inhibitory rate and the life-prolongation rate were observed after treatment.The cultured ovarian cancer cell strains of SKOV3 were randomized into 4 groups:model group,two FYT groups and cisplatin group.Apoptosis of SKOV3 was detected by enzyme-linked immunosorbent assay(ELISA)after culturing with the medicine for 48 hours.Results The tumor growth was inhibited to different extends in all of the treatment groups,the decrease of tumor mass weight was obvious in cisplatin group and FYT groups,and the body weight was increased in FYT groups and cisplatin+FYT groups(P
