Objective To explore the effect of in-and out-hospital continued nursing care on emotional state and health behavior of breast cancer patients undergoing chemotherapy after radical mastectomy.Methods Forty breast cancer patients undergoing radical chemotherapy in the oncology department of our hospital during March 2012 to February 2014 were put into the study group and another forty patients from the same department during March 2014 to February 2016 into the control group.The control group received traditional nursing care,while the study group in-and out-hospital continued nursing care mode.The health promotion lifestyle assessment scale (HPLP-Ⅱ),self rating anxiety scale (SAS) and self rating depression scale (SDS) were used for the evaluation before intervention and 2 months after the intervention.Results After intervention,there were no significant differences in the total scores on health behaviors and the dimensions,anxiety and depression (P＞0.05).Two moths after intervention,the scores on health behaviors and the dimensions in the study were all significantly higher than those in the control group and the scores on anxiety and depression were significantly lower (P＜0.05).Conclusion The in-and out-hospital continued nursing mode is beneficial for the breast cancer patients undergoing chemotherapy after radical mastectomy to adjust their emotions and improve their health behaviors.

Objective To explore the effects and mechanisms of nesfatin-1 injection in the central nucleus of the amygdale(CeA) on exploratory behavior in rats.Methods Fifty rats were divided into 5 groups randomly : nesfatin-1 low dose group, nesfatin-1 high dose group, SHU9119 group, SHU9119+nesfatin-1 low dose group and control group.Drugs were administrated via CeA to examine behavioral changes of rats by elevated plus maze model test and nesfatin-1 mRNA expression in CeA of anxiety rats (10 rats).Results Compared with the control group,anxiety behaviors of rats in nesfatin-1 low dose group and nesfatin-1 high dose group were improved remarkably,showing that the open arm entries were significantly reduced (OE, t=4.16-12.87, P＜0.01), open arm entry proportion was decreased remarkably (OE％, t=2.39-4.39, P＜0.01-0.05), and time proportion in open arm was decreased significantly (OT％, t=5.43-20.55, P＜0.01),which presented dose dependent.Compared with the control group, anxiety degree of rats in nesfatin-1 low dose group and nesfatin-1 high dose group significantly enhanced, showing that the rats head dipping reduced obviously (HD, t=6.97-16.73, P＜0.01) ,while rearing was increased significantly (RE, t=6.60-13.25, P＜0.01) ,which was presented dose dependent.Melanocortin receptor antagonist SHU9119 can partly eliminate nesfatin-1 induce-anxiety (t =2.11-3.08, P＜ 0.01-0.05).Real-time PCR results showed that nesfatin-1 mRNA expression of anxiety model rats was significantly increased (t =3.40-5.58, P＜0.05).Conclusion Amygdala nesfatin-1 can increase anxiety and fear of rats,which may be associated with melanocortin systems.

Objective To study the effects of chronic intra-abdominal hypertension (IAH) on the functions of vital organs. Methods From January 2004 to January 2008, 30 chronic massive ascites related IAH patients were enrolled including 12 colonic cancer cases, 7 pancreatic cancer cases, and 11 gastric cancer cases. Control group included 30 cases of gastrointestinal carcinoma without ascites hence no IAH. The specific malignances in this group were colonic cancer in 15 cases, pancreatic cancer in 8 cases, and gastric cancer in 7 cases. Age, gender and cancer stage were matched between the two groups. Symptoms in digestive, respiratoy and circulatory system and liver and kidney functions were recorded and KPS scores were compared respectively. Results The symptoms of abdominal distention in chronic IAH group and control group were presented respectively by 15 cases(50%) and 5 cases (17%) (P < 0.01). Symptoms of heart-throb or hypotension in the two groups by 10 cases (33%) and 3 cases (10%) respectively(P<0.05). Symptoms of asthma or chest distress in the two groups by 9 cases(30% ) and 1 cases (3%) respectively (P< 0.01). Liver function were abnormal in 16 cases (53%) and 6 cases (20%) respectively (P < 0.01 ), kidney functions were abnormal in 14 cases (47%) and 1 case( 3% ) respectively ( P <0.01 ) . There were 22 cases (73 %) and 7 cases (23 %) respectively ( P < 0.01 ) in the two groups with KIS score being lower than 40. Conclusions Chronic IAH causes malfunctions of vital organs deteriorating patients general status and even leading to abdominal compartment syndrome.

The chiral separation of three triazole pesticides, i.e. diniconazole, triadimefon and triadimenol was studied on a Chiralcel OJ-H and a Chiralcel OD-H HPLC chiral columns. The optical rotation quality of diniconazole and triadimefon enantiomers was measured and the absolute configurations of individual enan-)tiomers) were further concluded. On this basis, the absolute configurations of the four triadimenol stereoisomers were deduced via the reductive experiment of triadimefon to triadimenol. Furthermore, the chiral stability of the three triazole pesticides in organic solvents and buffer solutions was investigated. The results showed the obvious enantiomerization was observed as for triadimefon in methanol, ethanol and water, whereas dinicona-)zole) and triadimefon were chiral stable in organic solvents and water. The enantiomerization of triadimefon would be accelerated at higher temperature and in alkaline media.
