Objective To investigate the nursing of elderly patients with atrial fibrillation treated by atrioventrieular junction ablation combined with permanent pacemaker implantation. Methods The nurs-ing care process in 60 elderly patients with atrial fibrillation treated by atrioventricular junction ablation combined with permanent pacemaker implantation was reviewed and analyzed. Results All 60 patients had successful outcomes without any complication. Conclusions Preoperative psychological nursing and preparation, rigorous observation and nursing during and post operation guarantee a successful operation.

Totrain the evidence-based medicine thought style ofmedical students duringpro-bation teaching,we can enormously elevate the clinical teaching effect and prehension ability of medi-cal students.

Objective To observe the effect nourishing yin, clearing away heat and detoxicating therapy on post-operational patients of uterine cervix cancer. Methods 160 post-operational patients of uterine cervix cancer were randomly recruited into a control group and a treatment group, with 80 cases in each group. The control group was treated with conventional anti-infective and nutrition-supportive therapy. The treatment group received TCM therapy of nourishing yin, clearing heat and detoxicating. Observe complications and prognosis in both groups. Results In the treatment group, there were 21 patients bearing with complications (26.25%), but no case with tumor metastasis and relapse. While in the control group, there were 43 cases bearing with complications (53.8%), 3 cases relapsed but no tumor metastasis. The differences between the two groups were statistically significant (P=0.0064, P<0.01) .Conclusion The therapy of nourishing yin, clearing heat and detoxicating can effectively prevent postoperative complications and improve quality of life.

Infiltrated immune cells and cytokines in the tumor microenvironment may play different functions that appear tightly related to clinical outcomes.Radiotherapy mainly kills tumor cells through radiobio-logical effect,meanwhile it can indirectly change tumor immunologic microenvironment,and has a local or dis-tant anti-tumor immunological effect cooperatively.Animal experiments and clinical trials of radiotherapy com-bined with immunotherapy display well applied prospects,but the mode of radiotherapy in combined treatment needs further research.

Uterine natural killer cells (uNK) are distinct from peripheral blood NK (pbNK) cells,which constitute up to 70％ of the decidual leukocyte population in the first half of pregnancy,and are considered to have a cytokine-secreting role rather than cytotoxic function.It plays an important role in trophoblast invasion and uterine spiral artery remodeling.As a result of imbalance of uNK cells,pathological pregnancy appeared.Herein,the origin of uNK cells and its function in pregnancy were veviewed.

Objective To understand the influencing factors of satisfaction degree with nursing in our hospital by investigation in satisfaction degree in central injection room.Methods 252 patients were selected in our hospital from January to December 2011 as the research object,questionnaires were used to investigate the patients,and the influencing factors of satisfaction degree of nursing work were analyzed.Results Among the patients who accepted the investigation,patients' satisfaction scores were correlated with the patients' age,education level,income level,inpatient department,hospital stay time and whether they accepted an operation.Conclusions Nursing staff should pay attention to and strengthen the nursing work quality and efficiency,improve the satisfaction degree with nursing of clinical patients.

Objective To study the value of multi-slice spiral CT (MSCT)urography in diagnosis of urinary obstructive disease.Methods 48 cases with urinary system obstructive disease confirmed by operotion underwent MSCT scan,including plain and multi-phase contrast-enhanced scans.The images of CTA and CT urography were obtanined by the different three dimensional reconstruction.Results Of 48 cases,there were renal and uretal congenital malformation in 15 cases,uretal negative stone in 4,urinary inflammation in 5 ,renal,uretal and bladder tuberculosis in 6,hydronephrosis and hydroureterosis caused by exterior compression in 8 and neoplasm of urinary system in 10.Conclusion Multi-slice spiral CT urography is of significant applied value in diagnosis of urinary obstructive diseases.

Objective To evaluate the applied value of multislice spiral CT multiplanar reconstruction in diagnosing the trauma oforbit. Methods 40 patients with trauma of orbit underwent multislice spiral CT scan, the thickness of slices was 2 mm and collimator was 0.75 mm. Multiplanar reconstruction (MPR) and free angle parallel ranges reconstruction (PRR) were performed. CT findings of orbital trauma were analysed. The result passes through the surgery and the clinical confirmation.Results 14 cases with radiopaque foreign in orbit comfirmed by operation were accurately localized by MPR and PRR, but 6 cases were misdiagnosed by conventional CT. There were 21 cases with fracture of orbital wall, of them, 9 cases were not detected or partially misdiagnosed by plain CT. The damage of eye musculus rectus was in 16 cases, 6 cases were diagnosed by MPR+PRR. There were 16 cases with eyeball damage, of them , 4 cases detected by conventional CT difficultly, but they identified by MPR and PRR. The damage of optic nerve was in 5 cases, 4 cases were not discovered by conventional CT. Conclusion MPR and PRR are of important value in evaluating the orbital trauma.

OBJECTIVE To establish mice model of allergic rhinitis(AR) and study the role of Staphylococcal enterotoxin B(SEB)and ovalbumin(OVA)in the model,and investigate the change of regulatory T cell(Treg)in the nasal mucosa of mice.METHODS Forty Balb/c mice were randomized into OVA group(A),SEB group(B),OVA+SEB group(C)and normal solution group(D).AR model was established.The symptom scores and count of Foxp3 positive cells in nasal mucosa were analyzed by factorial design.RESULTS The symptom scores in Group A,B,C,D were 0.90?0.99,0.70?0.82,6.80?1.03,0.60?0.70 respectively.Group C was successfully established as AR model.OVA and SEB had interaction(P

Objective To establish mice modle of allergic rhinitis(AR) and to study the role of Staphylococcal enterotoxin B(SEB) and ovalbumin(OVA) in the modle.Methods Forty Balb/c mice were evenly randomized into OVA group,SEB group,OVA+SEB group and normal sodium group and AR modle was established.The symptom scores,total serum IgE concentration,IL-4 concentration were analyzed by factorial design.Meanwhile,the morphology change of nasal mucosa was observed.Results The symptom scores in OVA group,SEB group,OVA+SEB group and normal sodium group were 6.80?1.03,0.90?0.99,0.70?0.82,0.60?0.70 respectirely.The interaction of OVA and SEB had statistical significance(P
