With the social development,the number of obese people is increasing.Recent studies have shown that obese women to have breast cancer disease's risk is higher than normal body weight,and etabolic disorders growing threat to human health.Estrogen,aromatase have contributed to the occurrence and development of breast cancer after menopause.AMPK is a negative regulator of aromatase,it can inhibit proliferation of cancer cells by metabolic pathways.What's more metformin,resveratrol inhibited proliferation by this route has been confirmed in breast cancer cells.Here,the author do an overview of the role of obesity-related factor for postmenopausal breast tissue estrogen synthesis and metabolic abnormalities affect aromatase expression in breast.

ObjectiveTo determine the levels of 8-iso-prostaglandin F2α (PGF2α) in sera and lesions as well as antioxidant capacity in sera of psoriatic patients,and to assess their correlations with disease severity.MethodsSerum and skin tissue samples were collected from 15 healthy controlsand 50 patients with psoriasis vulgaris.Spectrophotometry was performed to determine the levels of total antioxidant capacity (T-AOC) and the activities of antioxidant enzymes such as superoxide dismutase (SOD),catalase (CAT) and glutathione peroxidase (GSH-Px) in serum samples.Enzyme-linked immunosorbent assay (ELISA) and immunohistochemical SP method were carried out to detect the expression level of 8-iso-PGF2α in the serum and tissue specimens respectively.ResultsThe psoriatic patients showed a significant decrease in the serum level of TAOC((12.78 ± 7.75) U/ml vs. (23.17 ± 8.81) U/ml,P＜ 0.01) as well as the activities of SOD((28.91 ±9.35) U/ml vs.(51.36 ± 7.92) U/ml,P＜ 0.01) and GSH-Px ((180.64 ± 47.70) U vs.(244.20 ± 66.68) U,P ＜ 0.01 ) compared with the healthy controls.The serum T-AOC level and SOD activity were lower in patients with severe psoriasis than those with mild or moderate psoriasis ((9.06 ± 5.30) U/ml vs. (15.27 ± 8.18) U/ml,(21.63 ± 5.28) U/ml vs. (33.76 ± 8.28) U/ml,both P＜ 0.01 ),while there was no significant difference in the activity of GSH-Px between patients with severe and mild or moderate psoriasis.The serum CAT activity was significantly higher in patients with mild or moderate psoriasis than in the healthy controls and patients with severe psoriasis ( (36.92 ± 11.31 ) U/ml vs.( 28.55 ± 8.51 ) U/ml and (24.15 ± 9.36 ) U/ml,P ＜ 0.05 and 0.01 ).Increased serum and lesional 8-iso-PGF2α levels were observed in psoriatic patients compared with the healthy controls ( (88.77 ± 25.27) ng/L vs.(38.34 ± 8.94) ng/L,0.0186 ± 0.0082 vs.0.0027 ± 0.0014,both P ＜ 0.01),as well as in patients with severe psoriasis compared with those with mild or moderate psoriasis(( 114.24 ±13.93) ng/L vs.(71.78 ± 14.35) ng/L,0.0279 ± 0.0027 vs.0.0125 ± 0.0030,both P＜ 0.01 ).The psoriasis area and severity index(PASI) score was negatively correlated with T-AOC level,SOD and CAT activities(r =-0.384,-0.573 and -0.444,all P ＜ 0.01 ),positively correlated with serum and lesional 8-iso-PGF2α levels (r =0.710,0.783,both P ＜ 0.01 ),and uncorrelated with GSH-Px activity.None of the parameters was correlated with the course of disease.ConclusionThe serum and lesional levels of 8-iso-PGF2α may be a more sensitive marker for oxidative damage and disease severity.

Objective To evaluate the effects of psychological nursing process on the quality of life and its related factors in maintenance hemodialysis patients.Methods Ninety maintenance hemodialysis patients from September 2013 to September 2014 were selected as research object,and they were divided into control group 45 cases and observation group 45 cases by random digits table method.The patients in control group received routine psychological intervention,while the patients in observation group received psychological intervention with nursing process.The two groups were evaluated and compared with Short Form 36 Health Survey Questionnaire score (SF-36), Self-Efficacy for Managing Chronic Disease(SEMCD) and Perceived Social Support Scale(PSSS) before and after the intervention at 6th and 12th month.The score changes of each scale were analyzed by repeated-measures analysis of variance and multivariate analysis of variance.Results The number of patients that had completed the whole intervention process was 42 in control group and 44 in observation group.The SF-36 scores of two groups were all increased gradually with the extension of intervention time (time effect, all P＜0.01), but compared with control group, observation group had a trend towards better SF-36 score except for the dimension of physical functioning(interactive effect, all P＜0.01).In all dimensions of SF-36, the scores of physical role,general health,vitality and social function in observation group as a whole were higher than those in control group (group effect, all P＜0.05).Similarly, the SEMCD and PSSS scores of two groups were all increased gradually with the extension of intervention time (time effect, all P＜0.01), but the increasing trend of observation group was more obvious than control group (interactive effect, all P＜0.01).Conclusions The application of psychological nursing process can effectively improve the life quality of maintenance hemodialysis patients, and have a satisfied long-term effect,which may be related to the continuous improvement of psychological nursing process on the self-efficacy and perceived social support of the patients.

Objective To evaluate the neurotoxicity induced by multiple exposures to sevoflurane anesthesia in the neonatal rats.Methods Thirty-two healthy SPF Sprague-Dawley rats of both sexes,aged 7 days,weighing 15-20 g,were randomly divided into 2 groups (n=16 each) using a random number table:control group (group C) and multiple exposures to sevoflurane anesthesia group (group Sev).On postnatal day 7,14 and 21,2.6％ sevoflurane was inhaled for 2 h in group Sev,while the mixed gas of oxygen and air was inhaled instead of sevoflurane in group C.Morris water maze test was carried out on postnatal day 32-36 to assess the cognitive function.On postnatal day 21 and 36,8 rats in each group were selected and anesthetized,and the cerebrospinal fluid was collected for determination of the concentrations of amyloid β-protein by enzyme-linked immunosorbent assay.Results Compared with group C,no significant change was found in the escape latency,movement time spent in the effective region of the platform,movement distance,the number of entries into the effective region,percentage of residence time,percentage of movement distance,and percentage of the number of entries (P＞0.05),and the concentrations of amyloid β-protein in the cerebrospinal fluid were significantly increased on postnatal day 36 in group Sev (P＜0.05).Conclusion Multiple exposures to sevoflurane anesthesia can induce central neurotoxicity,but do not induce changes in the cognitive function in the neonatal rats.

Emotional and cognitive disorders (EACD),such as depression and anxiety,have become very common in today′s society,seriously affecting human lives and health. Neural plasticity can reflect the anti-stress ability of the nervous system to the internal and external stimulation,and is capable of dynamic changes in structure or function to adapt to environmental changes,as is often manifested in the process of compensation and repair of nerve injuries. EACD is often accompanied by macroscopic and cellular morphological changes in brain tissues and functions. Thus,studies on the mechanisms of neural plasticity will contribute to the treatment of EACD. In this paper ,the role of neural plasticity in the active components of Chinese herbal medicine(ACCHM) is reviewed. The effects of ACCHM on 5-hydroxytryptamine(5-HT)system,and the antioxidant activities and neurotrophic effects of ACCHM are described. ACCHM can affect neural plasticity,playing a neuroprotective role by improving 5-HT levels,reducing oxidative stress in brain cells,and increasing the expression of brain derived neurotrophic factor(BDNF). In summary,one ACCHM could affect neural plasticity through one or more mechanisms. There are interactions between different mechanisms of the same ACCHM. Different ACCHM can play a synergistic effect on the enhancement of neural plasticity because of their different mechanisms.
