Objective:To explore the effect of humane nursing for bladder cancer patients complicated with cor-onary artery disease and analyze the ethical significance. Methods:Seventy-eight patients of bladder cancer com-plicated with coronary artery disease were recruited and divided into control group ( n=39 ) and observation group (n=39). Subjects of the observation group accepted routine care and humane care, while those in the control group only accepted routine care. Before and after the intervention, level of hope, anxiety and depression, quality of life were assessed. Results:After the intervention, the subjects′hope level in the observation group was signifi-cantly higher (P<0. 05) than before, and significantly higher than the control group (P <0. 05). Both in the control group and observation group, SAS and SDS scores significantly decreased (P<0. 05) than before, and the observation group compared with the control group were significantly improved ( P<0 . 05 ) . It suggested that symp-toms, psychological and emotional state, physical function, and other items of daily life scores were improved sig-nificantly after the implementation of humane nursing ( P<0 . 05 ) . Conclusion: Humane care mode can signifi-cantly increase the hope level of bladder cancer patients complicated with coronary heart disease, and is conducive to improving bad emotion and quality of life, which embodies the new nursing spirit, consists with the requirements of nursing ethics, and has a certain value to nursing ethics.

Objective To analyze the complications of total proctocolectomy with ileal pouch-anal anastomosis (TPC-IPAA) in treatment of severe or refractory ulcerative colitis (UC).Methods The retrospective cross-sectional study was conducted.The clinical data of 67 patients with severe or refractory UC who underwent TPC-IPAA in the Xinhua Hospital Affiliated to Shanghai Jiaotong University from February 2008 to October 2015 were collected.All the patients received open and laparoscopy-assisted TPC-IPAA,and two-stage or three-stage surgery was performed according to the patients' conditions.Observation indicators:(1) treatment and follow-up situations,(2) short-term complications after TPC-IPAA,(3) long-term complications after TPC-IPAA.The follow-up using telephone interview and outpatient examination was performed to detect the quality of postoperative life in patients and occurrence of complications up to July 2016.Measurement data with skewed distribution were described as M (range).The comparison of quality of pre-and post-operative life in patients was done using the paired t test.Results (1) Treatment and follow-up situations:all the 67 patients received successful surgery,including 45 with two-stage surgery and 22 with three-stage surgery.Thirty-seven patients underwent open surgery and 30 underwent laparoscopic surgery.The average frequency of postoperative daily defecation,average scores of quality of pre-and post-operative lifes were 5.6,0.47 and 0.67,respectively,with a statistically significant difference between preoperative indicators and postoperative indicators (t =-4.80,P ＜ 0.05).All the 67 patients were followed up for a median time of 4.6 years (range,1.0-8.4 years).(2) Short-term complications after TPC-IPAA:Of 67 patients,10 had short-term complications (some patients with multiple complications).One patient was complicated with presacral abscess secondary to sinus formation and then was cured by topical incision of sinus under colonoscopy.Five patients were complicated with anastomotic site-related complications of TPCIPAA,and 1 with pouch-anal anastomotic fistula combined with presacral abscess underwent drainage with ileostomy and didn't undergo stoma reversion of ileum.Two patients with fistula at the top of pouch were improved by surgery and repair.Of 2 patients with pouch-vagina fistula,1 underwent resection of pouch stump-vagina fistula and then were cured,and the space between pouch stump and posterior fornix was filled with a free greater omentum flap and temporary ileal bypass was simultaneously conducted.The other patient received twice transanal vaginal fistula repairs with advancement flap,and unclosed fistula was confirmed by angiography,with a clinical symptomatic relief.Eight patients with wound infection received actively dressing change after discharge,and no wound dehiscence was occurred.(3) Long-term complications after TPC-IPAA:28 of 67 patients had long-term complications.Twelve patients with intestinal obstruction underwent conservative treatments of gastrointestinal decompression,anti-inflammatory with corticosteroid and anti-infection with antibiotic,without the occurrence of severe intestinal perforation and prognosis needing surgical intervention,including 9 undergoing open TPC-IPAA and 3 undergoing laparoscopic TPC-IPAA.Thirteen patients with postoperative pouchitis received the conservative treatment of mesalazine.Three patients with failed pouch underwent small intestine permanent colostomy,including 2 with secondary pouch Crohn's disease and 1 with severe pouchitis.Conclusions TPC-IPAA is safe and effective in treatment of UC,with a lower incidence of complications.Anastomotic site-related complication of TPC-IPAA is the main short-term complication.And in the long-term complications,pouchitis is the most,followed it is intestine obstruction.

Objective To investigate the effect of astragalus polysaccharide (AP) on proliferation and apoptosis of human acute myelocytic leukemia cell line KG-1a and the underlying mechanisms.Methods Human acute myelocytic leukemia cell line KG-la was cultured under 37 ℃ and 5 ％ C02,when appropriate cell passage and cryopreservation were performed.After treatment for 48 h with different concentrations of AP,the proliferative activity and apoptosis rate of KG-1a cells were examined by CCK-8 assay and flow cytometry,respectively.The expressions of p-Akt and bcl-2 protein in AP-treated KG-1a cells were evaluated by Western blot.The expression of PTEN mRNA by quantified real-time PCR.Results The proliferative activity of KG-la cell was obviously suppressed by AP treatment,and the inhibition rate increased in a dosedependent manner.The flow cytometry showed that,compared with the control group,the apoptosis rates of KG-1a cells were significantly increased after treatment with AP for 48 h.The early apoptosis rates were (1.98±0.16) ％,(12.60±0.48) ％,(16.31±0.73) ％,the late apoptotic rates were (3.11±0.19) ％,(17.17±1.40) ％,(21.17 ± 0.81)％,the differences were statistically significant (P ＜ 0.05).Western blot showed that the expressions of p-Akt and bcl-2 protein in KG-1a cells decreased significantly after treatment with AP (P ＜ 0.05).In contrast,the mRNA level of PTEN increased (P ＜0.05),which was shown by real-time PCR.Conclusion AP could repress cellular proliferation activity of KG-1a cells,which could be attributed to inhibition of PTEN-PI3K-Akt signaling pathway.
