Objective:To understand the current status of health-related hardiness among breast cancer patients undergoing radiotherapy and to analyze its influencing factors, and to provide evidence for the development of psychosocial care programs for breast cancer patients undergoing radiotherapy.Methods:A total of 126 postoperative breast cancer patients undergoing radiotherapy were selected from the First Affiliated Hospital of Dalian Medical University from January to September 2018. The self-designed general data questionnaire and Health-related Hardiness Scale (HRHS) were used to analyze the current status and the influencing factors of health-related hardiness among patients.Results:The overall score of health-related hardiness among breast cancer patients undergoing radiotherapy was 127.61±20.19, which was located at the low medium level. There were significant differences in the scores of patients of different ages, education background, marital status, fertility status, children status, family history, religion, family income, and medical insurance forms ( t value was -3.800-8.128, F value was 8.906-274.271 P<0.01). The regression analysis showed that the influencing factors of health-related hardiness were age, family income, marital status, education background, family history, and religion. The degree of the dependent variable was 89.4%. Conclusions:Breast cancer patients undergoing radiotherapy have a low medium level of health-related hardiness, and are affected by age, family income, marital status, education background, family history, and religion.

Objective To explore the neuroprotective effects ofβ-aescinate on brain edema in rats of traumatic brain injury (TBI). Methods A total of 78 male SD (Sprague Dawley) rats were randomly divided into three groups: sham-operation group (Sham), traumatic brain injury group (TBI) andβ-aescinate group, with 26 rats in each group. Rats of Sham group were anesthetized and surgically prepared only, but were not induced by cortical contusion. Electronic brain cortical damage impactor (eCCI) was used for establishing TBI model in TBI group and β-aescinate group after opening the bone window. TBI group was only established TBI model, but no intervention. After establishment of TBI model in β-aescinate group, β-aescinate (5 mg/kg body weight) was intraperitoneally injected, once every 24 hours. The modified neurological severity scores (mNSS) was used for evaluating changes of neurological function. After 48 hours, SD rats were sacrificed for hematoxylin and eosin (H&E) staining (n=6). Additionally, water content of the brain tissue was evaluated using the wet-to-dry weight ratio (n=10). Evans blue assay was performed to investigate the blood-brain barrier (BBB) permeability (n=4). The expression of aquaporin 4 (AQP4) was measured by Western blot assay (n=6). Results Compared with the Sham group, neurologic deficit, increased brain water content and the expression of AQP4 were found in TBI group (all P<0.05). Moreover, BBB permeability was destroyed. However, β-aescinate can improve the neurological function, reduce the brain water content and significantly decrease the expression of AQP4 in TBI rats. The BBB permeability was significantly improved in treatment group (all P<0.05). Conclusion These findings suggest that β-aescinate can reduce cerebral edema and improve neurological outcome in SD rats after TBI. This neuroprotection may be related with the down-regulation of AQP4 protein.

Objective:To observe the effect of icariin on the osteoporosis of the ovariectomized rats,and to explore the mechanism.Methods:Fifty female rats aged 6 months were randomly divided into sham operation group, model group,positive drug group,low dose of icariin group and high dose of icariin group (n= 10).The rats in positive drug group were given with 1 mg· kg-1 nilestriol every week;the rats in low and high doses of icariin groups were given with 50 and 100 mg · kg-1 icariin every day.The bilateral ovaries of rats were excised by operation to establish the osteoporosis models.2 weeks after operation,the rats were treated with icariin for 12 weeks,and then they were sacrificed by drawing blood from abdominal aorta under anesthesia condion.The bone mineral density (BMD),serum biochemical indicators,bone histomorphology and the expressions of apoptosis-related proteins were detected.Results:Compared with sham operation group,the BMD of the rats in model group was decreased (P <0.01),the serum calcium level was decreased (P <0.05),and the serum phosphorus level was increased (P <0.05),and the serum BGP,ALP,NO and NOS levels were significantly decreased (P <0.05 or P <0.01).Compared with model group,the BMD of the rats in positive drug group and high dose of icariin group were obviously increased (P < 0.01 ), the serum calcium levels were increased, the phosphorus levels were decreased (P <0.05),and the BGP and ALP levels were increased significantly (P < 0.05 ). Compared with control group,the cortical in model group was thinned,the width of bone trabecula was reduced,the Bax and Caspase-3 expression levels in bone tissue were increased,and the Bcl-2 expression level was decreased.Compared with model group,the cortical in icariin group was thicked,the width of bone trabecula was increased,the Bax and Caspase-3 expression levels were decreased,and the Bcl-2 expression level was increased (P <0.05 or P <0.01). Conclusion:Icariin can protect the osteoporosis of ovariectomized rats,the function may be related to the inhibition of apoptosis.

Objective To observe the level of supportive care need and quality of life in patients postoperation for breast cancer and ac-cepting chemotherapy, and the relationship between them. Methods From September, 2015 to June, 2016, 235 patients with breast cancer af-ter surgery were conveniently sampled, and investigated with the general situation questionnaire, Supportive Care Need Survey Short-form (SCNS-SF34) and Functional Assessment of Cancer Therapy-Breast (FACT-B). Results A total of 230 patients were analyzed. Patients self-reported to need supportive care in all dimensions of SCNS-SF34, and the most frequency was in the health information (31.30％). The score of FACT-B was (93.25±23.53), that needed further improvement. The needs of supportive care in each dimension negatively correlat-ed with the scores of FACT-B in the dimensions (|r|>0.168, P<0.05) except society/family and function. Conclusion The patients with breast cancer need variety of supportive care, which may impact their quality of life.

Objective:To investigate the effects of anemoside B4 on apoptosis of retinal cells in diabetic rats.Methods:Sixty Sprague-Dawley rats were randomized into three groups: the normal control(control), diabetic rats(DM)and diabetic rats treated with Anemoside B4(B4)groups(n=20, each group). Rats in the DM and B4 groups were rendered diabetic with an intraperitoneal injection of streptozotocin(STZ, 60 mg/kg). After 3 days of successful modeling, rats in the B4 group were intraperitoneally injected with anemoside B4(5 mg/kg), twice/day, for 8 weeks, while rats in the control and DM groups were injected with an equivalent volume of normal saline.After 8 weeks of anemoside B4 and normal saline injection, rats were sacrificed and retinas were harvested for examination.Paraffin sections of retina were stained with the hematoxylin-eosin(H-E)method for morphological evaluation.Protein levels of Bax and Bcl-2 were detected by using Western blot.The expression of caspase-3 mRNA was detected with quantitative PCR.Results:H-E staining results showed the control group had intact retinal structure and clear morphological features, whereas disordered retinal structure, thinner layers, and sparse and disorganized cells were seen in the DM group.However, retinal structure and morphology were improved after treatment with anemoside B4.Compared with the control group, the protein expression of Bcl-2 was lower( t=57.81, P<0.01), the protein expression of Bax was higher( t=10.47, P<0.01), and the Bcl-2/Bax ratio was lower( t=23.98, P<0.01)in the DM group.Compared with the DM group, the protein expression of Bcl-2 was higher( t=41.07, P<0.01), the protein expression of Bax was lower( t=6.811, P<0.01), and the Bcl-2/Bax ratio was higher( t=14.70, P<0.01)in the B4 group.Caspase-3 mRNA expression was higher in the DM group than in the control group( t=7.916, P<0.01), but was lower in the B4 group compared with the DM group( t=6.221, P<0.01). Conclusions:Anemoside B4 can inhibit the apoptosis of retinal cells by up-regulating Bcl-2 expression and down-regulating Bax and caspase-3 expression in diabetic rats.
