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 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 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 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 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.

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 effects of different volumes of ropivacaine with the same solubility in supraclavicular brachial plexus block(SCBPB) under ultrasound guidance on ipsilateral diaphragmaticparalysis.Methods Seventy two patients (32 males,40 females, aged 18-65 years, of ASA Ⅰ or Ⅱ, scheduled for the right upper limb fracture internal fixation removal were randomized into group A (0.375% ropivacaine 20 ml) and group B (0.375% ropivacaine 30 ml), 36 cases in each group.The onset and duration of sensory and motor block were observed as well as complication.Diaphragmatic excursion were evaluated by M type ultrasound before and 30 min after drug injection under eupnea and forced respiration through observing diaphragmatic excursion to study diaphragmatic paralysis.Results The onset time of sensory block and maintaining time of sensory block or motor block had no significant difference between the two groups.Compared with group A,the onset time of motor block in group B was significantly shorter (P<0.05).Twelve cases (33.3%) in group A and 22 cases (61.1%) in group B respectively showed complete or partial hemidiaphragmatic paralysis 30 min after drug injection.Compared with group A, the rate of diaphragmatic paralysis in group B was significantly higher (P<0.05).Conclusion Supraclavicular brachial plexus block under ultrasound guidance with 0.375% ropivacaine 20 ml or 30 ml both can provide excellent anesthetic effect.0.375% ropivacaine 20 ml is less likely to lead to diaphragmatic paralysis.

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

OBJECTIVE: To explore the expression of interleukin-25 (IL-25) in chronic rhinosinusitis with nasal polyps (CRSwNP) and its potential significance in pathogenesis. METHOD: IL-25 expression in blood was detected by enzyme-linked immunosorbent assay (ELISA). IL-25 expression in tissue was detected by immunohistochemistry (LSAB method) from polyps (68 CRSwNP patients) and 55 inferior turbinate mucosa from patients with deviation of nasal septum served as control. Complete blood count and HE staining of blood and tissue eosinophil infiltration degree. RESULT: IL-25 expression in CRSwNP group were significantly higher than the control group, the difference was statistically significant (P < 0.01). IL-25 expression in local organizations was positively correlated with the number of eosinophil infiltration in CRSwNP group (r = 0.679, P < 0.01). CONCLUSION The expression of IL-25 in CRSwNP patients mutually reinforcing and might increase eosinophil infiltration and play an important role in the development of CRSwNP.
