Objective To investigate and analyze the characteristics of stressor that the undergraduate nursing students have to face at the clinical work in grade A hospitals , then to provide the scientific basis for clinical teaching management and reduce the pressures of undergraduate nursing students. Methods Questionnaires werehanded outto 80 undergraduate nursing students and datawere collected in the condition of their consents. Results The undergraduate nursing students had the higher scores on the dimensions of Patient Care and Nursing Work and stayed the pressure above average. Male and female undergraduate nursing students had the different top 5 stressors, the difference was statistical significance (t=2.434-3.644, P < 0.05). Conclusions The clinical teaching should care for the different stressors of male and female to reduce work and psychological pressure by taking effective measures, and give more attention to strengthen capacity-building of professional practice.

Objective To investigate the clinical efficacy and safety between laparoscopic and transabdomi -nal hysterectomy ,reduce the occurrence of complications measures .Methods On 154 cases of hysterectomy indica-tions were nonrandomly divided into two groups ,one group for the observation group of 79 cases of laparoscopic opera-tion,another group was control group of 75 patients with transabdominal operation;two groups had no significant differ-ence in age and disease .The clinical effect ,postoperative complications and safety between the two groups during and after operations were observed .Results The operation time of the laparoscopic group (72.0 ±13.2) min was signifi-cantly shorter than that of the control group (98.0 ±20.7)min (t=3.396,P=0.021);The bleeding quantity of the laparoscopic group(96.0 ±75.4)mL was significantly shorter than that of the control group (159.4 ±98.0)mL(t=9.680,P=0.014);The aerofluxus time of the laparoscopic group (17.2 ±4.2) h was significantly shorter than that of the control group(28.6 ±6.1)h(t=9.760,P=0.013).The average postoperative hospital stay time was significantly shorter in laparoscopic group(5.2 ±1.9)d than those in abdominal group(9.5 ±3.2)d (t=-5.025,P=0.018). The analgesic used in the laparoscopic group (3/89)was significantly shorter than that in the control group (48/78) (t=-8.820,P=0.000).Conclusion Laparoscopic hysterectomy is safe and effective .It is worth to promote in clinical,while improving the operation skills is the key to reduce the complications .

ObjectiveTo investigate the variation of T lymphocyte subsets and serum immunoglobulin for perioperative patients with thyroid cancer.Methods74 cases in our hospital for radical surgical resection treatment and 131I treatment after surgery were chosen as the observation group.Take the level of T lymphocyte subsets and serum immunoglobulin for statistics.And then compared with 40 healthy people.ResultsThe observation group before surgery:NK cells:( 19.1 ± 4.6) ％,T cells:(68.2 ± 5.5 ) ％,the serum immunoglobulin before surgery was ( 13.4 ±1.4μg/L).It was significantly higher than the control group [ ( 15.2 ± 3.2 ),( 65.2 ± 5.2 ),( 4.3 ± 0.5 ) ] ; CD4+(32.1 ± 2.9),CD4+/CDs+ ( 1.1 ± 0.3 ).It was significantly lower than the control group ( 38.1 ± 3.9,4.3 ± 0.5 ).The difference was statistically significant ( t =24.5,17.8,33.6,14.5,22.5,all P ＜ 0.05 ).The observation group after surgery,1 month after 131I treatment,3 months after 131I treatment,NK cells ( 17.0 ± 3.3 ),( 16.9 ± 3.0),( 16.7 ±3.4) and serum immunoglobulin (5.1 ±0.6),(6.2 ± 1.0),(6.1 ± 1.0) were significantly higher than control group,the difference was statistically significant ( t =18.4,11.6,9.2,5.4,8.1,7.3,all P ＜ 0.05 ).ConclusionThe variation of T lymphocyte subsets and serum immunoglobulin for perioperative patients with thyroid cancer was regular,and could be used as one of the indicators to determine for tumor recurrence or metastasis.

ObjectiveTo explore the effect of attention distraction in nursing children with maxillofacial trauma. Method Eighty-eight children with maxillofacial trauma were divided into control group and observation group with 44 patients in each group.Patients in the observation group was cared with attention distraction while the control group by traditional method of forced bondage.The two groups were compared in terms of wound treatment time and healing time,comfort degree and compliance of children.Results The wound treatment time and healing time in the experiment group were shorter than those in the control group.The comfort degree and compliance of children in the observation group were better than those in the control group(P<0.05).Conclusion Attention distraction for nursing children with maxillofacial trauma can improve children’s comfort and treatment compliance and shorten treatment time.

Objective: To study laparoscopic surgery for ectopic pregnancy complicated by hemorrhagic shock clinical efficacy and nursing research. Methods: Retrospective analysis of 60 cases of ectopic pregnancy complicated by hemorrhagic shock patients, divided into:the experimental group and control group of 30 cases, control group using traditional open surgery, laparoscopic surgery treatment groupclosely observe the clinical efficacy of the two groups. Results: Laparoscopic treatment of ectopic pregnancy in patients with hemorrhagic shock complicating operative time, blood loss than the control group; laparoscopic treatment of ectopic pregnancy in patients with hemorrhagic shock complicated exhaust time, postoperative morbidity and hospital stay was significantly lower than control group. Conclusion: Ectopic pregnancy laparoscopic surgery can improve concurrency cure rate of patients with hemorrhagic shock, better retention in patients with reproductive function, improve the patient's quality of life.

S100A6 is the member of the S100 family of EF-hand calcium-binding proteins,which participates in inflammatory reaction and regulates in cell growth,differentiation,growth inhibition and apoptosis.Recently it has been reported that S100A6 plays a key role in neoplastic transformation,proliferation and invasion of tumor,it may become a potential target in the diagnosis and treatment of tumor.Here is to review the recent advances in the research on this molecule,including its structure,function mechanism,and its relationship with the gastrointestinal cancer and so on.

OBJECTIVE:To investigate pharmacokinetic parameters of glutathione( GSH )after intraveneous injection(iv) in dogs. METHODS: A single dose of 40 mg?kg-1 was given to 12 Beagle dogs by iv,their plasma blood sample in different times were collected and concentrations of GSH were detected by HPLC,then the pharmacokinetic parameters were calculated using 3p97 software program. RESULTS: The concentration-time curves of GSH with iv fitted to two-conpartment model. The main pharmacokinetic parameters including t1/2?、t1/2?、V(c)、CL(s)、AUC0～t were(2.32?1.26) min,(16.03?6.58) min,(1.13?0.54) L?kg-1,(0.080?0.027) L?min-1 and (546.69?189.45) ?g?h?mL-1,respectively. CONCLUSION: GSH in circulatory system of dogs after iv has short retention time and quick elimination.

The new healthcare reform project raised the thought that basic medical care service should be available to each individual,and the objective of an entire-people covered medical care assurance,which provide policy guarantee for the improvement of medical care service.To achieve the real advancement of medical care service,many endeavors are involved as follows.It is necessary to strengthen the responsibility share of all-level governments,guarantee the input for medical care adapted to local conditions and meanwhile embody medical care impartiality,strengthen the quality construction within medical care institutions,develop the role of medical care service in directing the patients triage which guides residents to get access to community medical centers,and respect individual's own choice for medical care so as to achieve the competition mechanism among medical care service designated hospitals.
