Objective To explore the effects of two diffeerent nursing interventions on postoperative pain of patients with thoracic tumor. Methods Postoperative patients with thoracic tumor (126 cases) were ran-domly divided into the experimental group(64 cases) and the control group (62 cases). The experimental group combined stages of assessment methods with the three-step analgesic ladder for cancer pain which the WHO recommended. Timely and reasonable use of analgesic agents ensured control of pain effectively. The control group was given disposal only when patients complained pain. Sleep, effective cough of sputum, related indica-tors of vital signs and the time of first ambulation were observed in the two groups. Results The inci-dence of patients' abnormal respiratory rate, accelerated heart rate and decreased oxygen saturation levels in fingertip in the experimental group were significantly lower than those of the control group(P<0.05). Within 3 days after surgery, the proportion of the experimental group patients whose cough and expectoration re-flex score was good, without insomnia and with first ambulation was significantly higher than that of the control group (P<0.05). Conclusions Adoption of stages of assessment and initiative and effective pain control for patients with thoracic tumor of postoperative pain can significantly improve the quality of care, pro-mote the recovery of physiological function, and reduce the incidence of postoperative complications.

Results The nursing quality standard system was established, the quality of care and patient satisfaction with nursing work were both improved. Conclusions The application of the key factors is the basic guarantee for effective management of nursing quality, which provides high quality nursing service for patients in hospital.

Objective To evaluate the effects of two different kinds of airway humidification for tracheostomy patients, and to provide their relevant clinical effect and suggestions for their use. Methods Online databases, including PubMed, EMBASE, JBI evidence-based nursing center library, the Cochrane Library, and Chinese databases (CNKI, Wanfang database, VIP, CBM) were searched systematically up to March 2015. Randomized controlled trials (RCTs) were considered eligible for inclusion if the following criteria were met: no history of respiratory tract infection; satisfactory nutritional status; tracheotomy performed; 18 years older. Two different humidification methods were used. Continuous airway humidification was used in the experiment group, while intermittent airway humidification was used in the control group. Two qualified reviewers reviewed the original articles, evaluating the quality of articles, and data were extracted independently. The enrolled RCTs were analyzed by Meta-analysis. Results A total of nine RCTs were included, containing 631 cases, among them 316 cases in expertment group, and 315 cases in control group. Continuous airway humidification was shown to be able to reduce the incidence of irritable cough [odds ratio (OR) = 0.20, 95% confidence interval (95%CI) = 0.12-0.34, P < 0.000 01], bleeding form mucosa of respiratory tract (OR = 0.25, 95%CI = 0.14-0.45, P < 0.000 01), sputum conglomeration (OR = 0.19, 95%CI = 0.10-0.39, P < 0.000 01), and pneumonia (OR = 0.29, 95%CI = 0.19-0.45, P < 0.000 01). The funnel plots were largely symmetrical, suggesting there was no publication bias in the Meta-analysis of two methods for airway humidification for tracheostomy patients. Conclusion Because the number of including articles was relative small, and the quality of some articles was poor, it is impossible to draw a reliable conclusion that continuous airway humidification could lower the incidence of complications for patients undergone tracheostomy.

As to clarify the cause of cervical cancer,early normative and effective screening can decrease the incidence and mortality of precancerous cervical lesions and cervical cancer.At present the main methods for cervical cancer screening are pap smear method,acetic acid shading to naked eye observation,iodine staining to the naked eye observation,liquid based cytology and human papillomavirus DNA testing methods.Screening techniques and strategies are different in different areas and countries because of unbalanced economic development.

Objective To introduce a simple and easy method for cell apoptosis analysis as an example with artemisinin to induce apoptosis of human U251 cells. Methods Human U251 cells,cultured in suspension and treated with artemisinin,were freeze-thawed. 30 ?L of 3 mmol/L PI was then added and mixed. After being placed under room temperature for 5 min,the cellular ploidy was analyzed by flow cytometry,and the ratio of cell apoptosis was calculated. Results The ratio of human U251 cell apoptosis induced by artemisinin at a dose of 1?10-4,1?10-5 and 1?10-6mol/L was 33.2%,24.0% and 8.0%,respectively. Conclusion The results showed that artemisinin significantly induced the apoptosis of human U251 cells in a dose-dependent manner. Using this method to analyze cell apoptosis can reduce the procedure of cell treatment and avoid many influential factors. Therefore,it can be regarded as a simple,accurate and rapid method for detecting cell apoptosis.

Objective To investigate the efficacy of conservative treatment with laparoscopy for patients with ectopic pregnancy.Methods From January 2000 to December 2005,76 patients with ectopic pregnancy received conservative treatment by laparoscopy in our hospital.The data of the patients were analyzed retrospectively.Results In this series,fenestration of the Fallopian tube was performed on 42 cases,salpingostomy on 21,fimbrial expression on 8,and segmental resection and end-to-end anastomosis on 5.Salpingography showed that the Fallopian tube was patent after the operation in all of the patients.The mean operation time was(58.5?19.4) minutes(ranged from 35 to 105).The serum level of ?-hCG decreased to a normal range in 3 weeks postoperation.Follow-up was available in 61 cases for 1 year,during which 35 of the cases(57.4%,35/61) had intrauterine pregnancy;2(3.3%) had spontaneous abortion,and 2(3.3%) showed ectopic pregnancy;the other 22(36.1%) had no pregnancy.Conclusions Conservative treatment by laparoscopy is safe and effective for ectopic pregnancy.To avoid repeated ectopic pregnancy,?-hCG monitoring after the operation is necessary.

Solid internal pressure is one of the important parameters in traffic bridge and defense field.However, the existing testing equipments have the defects of serious electromagnetic interference, poor reliability, and poor accuracy.To overcome the above problems, a fiber bragg grating (FBG) high pressure solid pressure sensor which used thin plates as elastic bearing diaphragm and applied the deflection under pressure to pull the pressure sensitive grating to realize pressure sensing axial displacement was designed.By calculating on the structure according to the measurement range and finite element simulation, its feasibility was confirmed.In the laboratory with constant temperature, the pressure calibration experiment was carried out, and the temperature compensation was performed by the temperature compensation grating in the same temperature field to correct the temperature drift of strain grating.Experimental results showed that the newly devised FBG pressure sensor could sense the pressure as high as 50 MPa, with a linearity of 99.2%.

Objective To investigate the tolerance of chemotherapy based on gemcitabine and cisplatin in elderly patients (> 70 years old) with advanced pancreatic cancer. Methods Retrospective analysis in 34 elderly patients with advanced pancreatic cancer between January 2004 and January 2009 was performed. Results 6 patients had partial remission (PR) and 16 patients had stable diaease (SD). The clinical benefit response (CBR) rate was 64.7%. 18 patients reduced their analgesics dose exceeding 50% , as well as pain intensity descended exceeding 35% , 22 patients had the weight increased more than 7% and had improved general well-being. The incidence rate of nausea and vomiting was 38. 2% (13/34) , 4 patients had worsened liver function and aggravated skin and sclera stained yellow. Incidence of Ⅲ- Ⅳ myelosuppressive was 34. 6% , and there were decrease in the number of white blood cell, hemoglobin, platelets to some extent, the rate of thrombocytopenia was 28. 3% (12/34) , blood routine normalized after using G-CSF. There was no occurrence of peripheral neurotoxicity or chemotherapy-related death. Conclusions Chemotherapy of gemcitabine in combination with cisplatin was tolerable for elderly patients with advanced pancreatic cancer who were in good condition of behavior.

Objective To investigate the expression and clinical significance of the long non-coding RNA MALAT-1 in epithelial ovarian cancer (EOC).Methods The expressions of MALAT-1 mRNA in 29 EOC tissues and 20 normal ovarian tissues were detected by real-time fluorescence quantitative PCR.The relationships between the expression of MALAT-1 mRNA in EOC and its clinical pathological characteristics were analyzed.Results The expression of MALAT-1 mRNA in EOC tissues was lower than that in normal ovarian tissues (0.089±0.090 vs 1.450±1.404,t =4.331,P ＜ 0.001).The expression of MALAT-1 mRNA in advanced (Ⅲ-Ⅳ) stage tissues was significantly lower than that in early (Ⅰ-Ⅱ) stage tissues (0.044±0.043 vs 0.174±0.095,t =-5.125,P ＜ 0.05).The expression of MALAT-1 mRNA was significantly lower in poorly differentiated and poorly-moderately differentiated ovarian cancer than that in well differentiated ones (0.070 ±0.091 vs 0.161±0.021,t =2.409,P =0.023).The expression of MALAT-1 mRNA was significantly lower in tissues with the lymphonode or omental metastasis than that in tissues without invasion (0.045±0.047 vs 0.142±0.102,t =3.378,P =0.002).Conclusions The expression of long non-coding RNA MALAT-1 is lower in EOC,which is related to tumor grade,clinical stage,lymphonode and omental metastasis.It is suggested that MALAT-1 may play an inhibition role in the progress of ovarian cancer.
