Objective To explore the relationships of post- traumatic growth with self- care efficacy and psychological resilience in patients with breast cancer. Methods Totally 303 patients with breast cancer were investigated with Post- traumatic Growth Inventory (PTGI), Chinese version of Strategies Used by People to Promote Health (C- SUPPH) and Connor- Davidson Resilience Scale (CD- RISC). Results The total score of PTGI was 63.74±13.00 and the status of post- traumatic growth in breast cancer patients was in middle level, with a highest interpersonal score of 24.49±5.05, a lowest mental change score of 3.84± 1.91. Correlation analysis showed that post- traumatic growth was positively correlated with the level of self- care efficacy and psychological resilience (P<0.01 or 0.05). Regression analysis showed that self- care efficacy and psychological resilience in breast cancer patients could effectively predict the post- traumatic growth with an explanation rate of 36.1%. Conclusions Self- care efficacy and psychological resilience in patients with breast cancer are closely correlated with post- traumatic growth. It is suggested to take appropriate measures to promote post-traumatic growth of the breast cancer patients.

Objective To discuss and to compare the curative effects of interventional embolization with different embolic agents in treating giant hepatic cavernous hemangiomas. Methods From 2008 to 2010, a total of 30 cases with clinically proved hepatic cavernous hemangioma were treated with interventional embolization. According to the embolic agents used , the patients were divided into pingyangmycin-lipiodol emulsion mixed with sodium alginate microspheres group(PLE+KMG, group A, n=15) and pingyangmycin-lipiodol emulsion group (PLE, group B, n=15). CT scanning was performed one, 3, 6, 12 months after the treatment to evaluate the curative effect. Results The technical success rate was 100%in both groups. The mean PLE dose used in group A and B was (10.9 ± 5.2) ml and (11.4 ± 4.9) ml respectively, the difference between the two groups was not significant (P > 0.05). CT reexamination performed one, 3, 6 months after the treatment showed that a reduction in tumor volume over 50%in group A was seen in 9, 11 and 14 cases respectively, while in group B it was 0, 3 and 5 cases respectively (P <0.05). One week after the procedure, the degree of pain in patients of group A was more severe than that in patients of group B, the difference between the two groups was statistically significant (P < 0.05). Slight abnormal hepatic function was seen in some patients of both groups, which presented mainly as an elevation of aminotransferase, which returned to normal after symptomatic medication. Follow-up with questionnaire indicted that patients of group A were more satisfied with the treatment than the patients of group B. Conclusion Transhepatic infusion of pingyangmycin-lipiodol emulsion is a safe and effective treatment for giant cavernous hemangioma of the liver. Combination use of pingyangmycin-lipiodol emulsion and sodium alginate microspheres can obviously reduce the tumor size mainly in the first and the third month after the treatment, besides it produces instant clinical effect although the pain is more severe than in patients treated with pure pingyangmycin-lipiodol emulsion.

Objective To explore the effects of modified herringbone-Trendelenburg position during gynecological laparoscopic operation of the elderly. Methods A total of 60 elderly patients undergoing gynecological laparoscopic operation under general anesthesia were recruited and assigned to the observation group (30 cases) and control group (30 cases) by random digits table method with 30 cases each according to admitting time;Patients in the control group were placed in conventional Trendelenburg position, while the patients in the observation group were positioned in modified herringbone-Trendelenburg position .Intraocular pressure (IOP) were measured in the patients at anesthesia induction (T1),5 minutes after general anesthesia in supine position (T2) , and 5 minutes after pneumoperitoneum while in the operation position (T3) , every 30 minutes (times 4 to 11), while supine at the end of pneumoperitoneum (time 12) and before awakening (time 13);Patients were followed up at 24 h and 48 h after surgery, researcher investigate and record the scores of the Operation Position Comfort Questionnaire, the situation of the pain in the shoulder and postoperative complications of the lower limbs. Results There was no statistically significant difference (t=-1.098,-0.772,-0.656, P>0.05) of the IOP at T1, T2, T13. The IOP in the observation group had statistically significant difference compared with the control group at T3 to T12 (t=6.523-19.866, P<0.01). The incidence rate of the postoperative complications of the lower limbs in the observation group was 6.7%(2/30) lower than 26.7%(8/30) of the control group (χ2=4.320, P<0.05) and the VAS scores of the patients in the two groups was statistically significant (t=2.471, P<0.05). The incidence rate of the postoperative shoulder pain in the observation group was 10.0%(3/30) lower than 43.3%(13/30) of the control group (χ2=8.523, P<0.01), and the Visual Analogue Scale scores of the patients in the two groups was statistically significant (t=3.575, P<0.05).The scores of the Operation Position Comfort Questionnaire in the observation group was higher than the control group (t=-2.319, P<0.05). Conclusions Modified herringbone- Trendelenburg position can reduce the elevation of intraocular pressure in elderly patients without affecting the operation ,and effectively improve the comfort of the operation position of the patients, reduce the incidence rate of the shoulder pain and postoperative complications of the lower limbs, is conducive to the operation safety of elderly patients.

Objective To investigate the clinical and angiographic characteristics of no reflow phenomenon after primary percutaneous coronary intervention (PCI) with acute myocardial infarction (AMI).Methods A total of 319 patients with AMI undergoing primary-PCI was divided into no-reflow and normal reflow groups.The incidence of no-reflow phenomenon,the clinical date,angiography findings,and surgical date were compared between two groups.Results No-reflow phenomenon occurred in forty(13.4％)of the patients after primary PCI.There was dramatic difference in combined hyperlipidemia,angina pectoris history before AMI,heart function ≥2 grades on admission,the length of the vascular lesions,vascular stenosis degree,blood clot load level,coronary artery opening time,and the expansion of the balloon between no-reflow and normal blood flow groups.Multiple logistic regression analysis identified that angina pectoris history before AMI,heart function classification on admission,high thrombus burden,the expansion of the balloon,and coronary artery opening time on angiography as independent predictors of no-reflow phenomenon.Conclusions The occurrence of no-reflow phenomenon after primary PCI was associated with high cholesterol history,no history of pre-infarction angina,heart function classification on admission,long vascular lesions,narrow degree of heavy,blood clots in the high load,coronary artery opened long time,and the expansion of the balloon more frequently.
