Objective To study application of nursing intervention in perioperative care of breast cancer patients. Methods A retrospective analysis of 97 cases of breast cancer patients in our hospital was carried out. Psychological counseling and perfect preparation was executed preoperation, making patients emotional stability during the operation, and implemented effective measures after operation,besides relevant guidance was given upon discharge. Treatment effect was observed. Results 97 patients were cured and discharged, and only 1 case appeared ipsilateral upper extremity edema, other patients were in good conditions. Conclusions Perioperative nursing interventions can effectively relieve pressure of patients, improve effect of operations, prevent or reduce postoperative complications and promote early rehabilitation.

[Objective]To investigate the operation indications and techniques of the ISOLA spinal system in reconstruction of the lumber-pelvis continuity after resection of high-level sacral tumors. [Method]A retrospective study was performed in 43 patients with high-level sacral tumor (HLST) between July 2001 to January 2007. Symptoms, signs, histological findings of the tumors and their outcomes were analyzed. All patients underwent resection of HLST and spinopelvic reconstruction with ISOLA spinal system,11 unilateral and 32 bilateral.[Result]Among the 43 patients, 33(77.1%)had chordoma, giant cell tumor of bone and neurogenic tumors. Thirty-four patients alive were followed-up for an average of 35 months(12~62 months), 5 patients had a recurrence of chordoma and 29 patients with HLST were under control. The pain originated from the lumbosacral joint and the spinal nerve root was obviously relieved.The patients could stand and ambulate normally. No loose screw or broken rod were found.X-rays showed no signs of the enlarged screw canal or lowered lumbar spine.The effect was 76.5%(26/34) excellent judged by the ISOLS system.[Conclusion]Spinopelvic reconstruction by ISOLA system after resection of HLST is characterized by easy manipulation, less complications and instant stable fixation. It may be widely used in the clinical practice.

OBJECTIVE: To promote the rational use of antibiotics.METHODS: A retrospectively analysis was conducted on the application of antibiotics in 4 186 discharge case histories in 2005.RESULTS: Of the total 4 186 cases,the application rate of antibiotics was 64.48%,among which,56.17% were prophylactic use of antibiotics and 5.89% used antibiotics without indication.The consumption of antibiotics occupied 45.90% of the total medicines consumed.The nosocomial infection rate was 4.16%,of which,23.56% were fungous infections.The incidence of adverse drug reactions was 2.56%.CONCLUSION: The rate for the prophylactic use of antibiotics in our hospital is on the high side,which may result in high incidences of drug resistant strains and nosocomial infections,therefore,measures should taken to tight the control of the administration of antibiotics.

Objective To investigate the effects of propofol on lung nitric oxide synthase (NOS) in rats and the mechanism of its pulmonary artery and bronchus dilating effects. Methods Forty SD rats weighing (210+40)g were randomly divided into two groups: propofol group received propofol 100mg-kg-1 ip and when its righting reflex was lost propofol was continuously infused at 10mg'kg-1 h-1 through the vein in the tail for 10min, then the animal was killed; control group received normal saline 10 ml'kg-1 ip and the animals were killed 20 min later. After sacrificing the animals the chest was opened and the lungs were removed. The NO level in the broncho-alveolar lavage fluid (BALF) was measured in 10 animals. NOS activity and NO content of the lung tissue homogenate were examined in 10 animals. Cellular distribution and expression of endothelial NOS (eNOS) and neural NOS (nNOS) in the lung were examined by immunohistochemistry in 5 animals. Results The NO level in BALF, NO content and NOS activity in the lung homogenate were significantly higher in propofol group than those in control group (P

[Objective To evaluate the teaching effects and advantages of problem-based learning (PBL) teaching mode based on network in the clinical practice of obstetrics and gynecology. Methods 2007 grade intern students in department of obstetrics and gynecology in Beijing Tongren Hospital of Capital Medical University were divided into 2 groups:control group (18 seven-year program and 11 five-year program)and experiment group (17 seven-year program and 10 five-year program). Traditional teaching was conducted in control group:interns and teacher completed teaching ward round several times according to the teaching requirement. PBL based on network was conducted in experiment group:tea-chers asking questions-data collection-learning and discussing-demonstrating and arguing-discussing and summarizing teaching process. Then the effects of different teaching methods were evaluated by clinical practice skill and theoretical test. SSPS13.0 statistical software was used for data analysis and measurement data were expressed as x±s. T test was conducted among groups. Results As for clinical practice skills, scores in PBL group (seven-year program and five-year program )were higher than those of traditional group [seven-year program:(190.47±2.30)vs (87.42±2.93);five-year program:(92.95±2.20)vs (90 . 09 ± 2 . 70 )] . There was no difference between the two groups in scores of theoretical test . In clinical practice skills,scores of general skill and clinic case analysis showed significant differences be-tween PBL group and traditional group. Conclusions PBL tea-ching mode based on network can improve the quality and effectiveness of the clinical practice of obstetrics and gynecology, especially in the social, technical,and knowledge dimension.

Objective To explore application effect of evidence-based nursing in operation of rupture of liver and apleen. Methods 108 patients with rupture of liver and spleen received evidence-based nursing during perioperative period, that is, to determinate nursing problems needed to prove, retrieve and analyze related articles, make the best nursing mode and prevent complications. Results Complications appeared in 15 patients, intra-abdominal hemorrhage in 4 patients, infection in 7 patients and splenic fever in 4 patients. All were corrected in time, and no case showed thrombosis and organ failure. Conclusions EBN can prevent post-operative complications for patients with rapture of liver and spleen and improve nursing quality.

Objective To establish the diagnosis of am niotic fluid em bolismwith blood sam ples by liq-uid-based cytology technique and to study the validity of m ethod. Methods The blood sam ples were collected from patients who suffered from am niotic fluid em bolism. The com ponents of am niotic fluid in blood samples were examined with blood smear by two direct smear methods(supernatant smear, sedi-ment smear) and two liquid-based cytology methods(autom atic smear, manual smear). The positive de-tection rate of each m ethod was calculated. Results The positive detection rates of two liquid-based cy-tology methods(84.6% and 92.3%, respectively) were m uch higher than those of two direct methods(53.8% and 61.5%, respectively). Conclusion The liquid-based cytology technique could im prove the positive detection rate of am niotic fluid em bolism.

Objective To examine the effect of epigallocatechin gallate (EGCG) at different concentration (0,10,25, 50 and 100μmol/L ) on proliferation rate and apoptosis of nasopharyngeal carcinoma cell line C666-1 in vitro, and elucidate the role of silent information regulator 1 (SIRT1). Methods The proliferation rate in vitro of C666-1 cells stimulated by EGCG at increasing concentrations (0,10,25,50,and 100 μmol/L)for 24 h or at concentration of 50μmol/L for 0,6,12 h and 24 h were detected by cell counting kit-8 (CCK-8) assays. Cell were treated with EGCG at concentration of 0,25, 50 and 100 μmol/L for 24 h, cell apoptosis was anylysed by TUNEL assay and expression levels of SIRT1 protein was detected by western blotting. Results EGCG suppressed cell proliferation of C666-1 cell line in a concentration-dependent manner at concentration of 0 ,10,25,50,and 100μmol/L, and in a time-dependently when treated with 50 μmol/L for 12 to 24 h(P<0.05). After treated for 24 h with different concentration of EGCG at 0、25、50、100 μmol/L, cell apoptosis increased at concentration of 50 to 100μmol/L and expression of SIRT1 decreased in a concentration-dependently (P<0.05). Conclusion EGCG induced cell apoptosis of C666-1 cells by down-regulating SIRT1 expression.
