Recently the effect of tumor marker on bone metastasis in breast cancer was regarded increasingly. The article reviewed the development of tumor marker research on diagnosis, treatment of bone metastasis in breast cancer.

Stem ceils transplantation is one of the potential therapeutic strategies for Alzheimer's disease (AD). Many animal models following stem cell transplantation showed improvement in memory and cognitive function. However, the pathological changes in AD, such as arnyloid beta deposits, negatively affect the survival and differentiaition of stem cells. Stem cells transfectcd with neprilysin or administration of phenserine could at-tenuate these adverse effects. Genetic modification of stem cell by over expression of neurotrophic factors could attenuate the adverse effects not only on stem cells but also on degenerative neurons. Further investigation on how to overcome the adverse effects of phathological factors in AD on stem cells and maximize the therapeutic effects of stem cells would support the hope for introduction of stem cells transplation into clinical application.

Objective To evaluate the clinical significance of single-incision video-assisted thoracoscopic surgery(SI-VATS)in elderly patients undergoing pneumonectomy. Methods The clinical data of elderly patients received pulmonary resection by SI-VATS and three-port video-assist-ed thoracoscopic surgery(TP-VATS)last year were analyzed. Results The SI-VATS group was significantly better than the TP-VATS group in in-cision length,drainage time,as well as the 1st,3rd,7th day VAS score and one month satisfaction after operation(all P<0.05). However,no sig-nificant difference was found in operation duration,blood loss,lymph node number,or complications(all P>0.05). Conclusion SI-VATS pul-monary resection is safe,feasible and with less invasive.

Objective To investigate the effects of WeChat follow-up of relatives on knowledge cognition, change of behavior, visual acuity and blood glucose for diabetic retinopathy (DR) patients.Methods Totally 107 typeⅡdiabetic patients from January 2014 to December 2015 in the Department of Endocrinology were enrolled in the study, with the inclusion criteria of 60 years of age and older and diagnosed with diabetic retinopathy. Subjects were divided into the WeChat group (53 cases) and the control group (54 cases) based on the order of enrollment. The control group was given routine care and health education, while the WeChat group was given additional follow-up of relatives through WeChat with distribution of health education messages for the management of DM and DR once each week for 12 months. Questionnaires were used to collect information on patient's knowledge of DR prevention & treatment and behavior change, FBG, PBG, and HbA1c, and visual acuity were also collected to assess the effectiveness of the intervention. Chi-square test was used to compare the patients' cognitive rate, behavioral change and stage of retinopathy. The t-test was used to compare fasting blood glucose, 2 hours postprandial blood glucose, glycosylated hemoglobin and visual acuity. Results Cognitive Knowledge change on DR were analyzed for the following questions:the time of the first fundus examination after diagnosis of diabetes and occurrence of systemic complications; what are key measures for prevention of early blindness in patients with DR;fundus checkup requirements while blood glucose control is ideal;types of major eye complications for diabetic patients; when laser treatment should be done for DR patients; how long apart should patients check the fundus;what is the normal range of blood glucose;and the types of server damages of DR;etc. The cognitive rates of WeChat group after follow-up were as follows 88.7%, 67.9%, 56.6%, 96.2%, 79.2%, 67.9%, 69.8%, 94.3%, 75.5%. WeChat group compared with the Control group after follow-up (χ2 values were 16.77, 30.76, 16.30, 7.75, 9.68, 36.03, 9.25, 10.57and 9.41, respectively, all P<0.01), the difference was statistically significant. The results of WeChat group before and after the follow-up were (χ2 values were 19.41, 38.22, 17.90, 8.23, 9.34, 38.22, 21.81, 12.08 and 25.52, respectively, all P<0.01), the difference was statistically significant. The cognitive rate for DR risk factors for the WeChat group was 24.5% before follow-up and 43.4%after follow-up;the after follow-up difference between WeChat group and the Control group was statistically significant (χ2=5.33, P<0.05). WeChat group before and after follow-up comparison (χ2=4.21, P<0.05) was also statistically significant. For values of fasting blood glucose, 2 h postprandial blood glucose and glycosylated hemoglobin, results of WeChat group before follow-up were as follows (13.18± 4.46) mmol/L, (16.17 ± 3.97) mmol/L, (10.18 ± 2.76)%;results of WeChat group after follow-up were (8.45 ± 2.26) mmol/L, (11.34 ± 2.34) mmol/L,(7.83 ± 1.40)% respectively. The after follow-up comparison between WeChat group and the Control group showed statistically significant differences (t values were-7.06,-7.30, and-6.37, respectively, all P<0.01). Within the WeChat group, before and after follow-up comparison were all significantly different (t values were 6.83, 7.59 and 5.54, respectively, all P<0.01). The vision of WeChat group before follow-up was 0.68 ± 0.18, after follow-up was 0.71 ± 0.20. There were no significant differences in the two groups after follow-up, before and after follow-up WeChat group, the Control group before and after follow-up about visual acuity comparison (t values were 1.02,-1.10, and 0.57, respectively, all P>0.05). The two groups of patients were compared in balanced diet, regular eating time, meal volume, wearing loose clothing and exercise shoes and socks before each exercise, exercising for more than 30 min, weekly checkup of blood glucose, blood sugar test before and after the exercise and other measurements of behavior changes were significantly different (χ2 values were 11.54, 11.77, 13.68, 5.89, 10.23 and 8.72, respectively, all P<0.01 or 0.05). There were no significant differences in self-withdrawal of medication and Retinopathy stageⅠand stageⅡpatients and between these two patient groups (χ2 values were 1.20, 0.01 and 0.01, respectively, all P>0.05). Conclusions The practice of WeChat follow-up of relatives can improve cognition ability for DR patients aged 60 years and older, it can promote the healthy behavior and the BG monitoring effectively.

Objective To evaluate the effect of group psychological intervention and relaxation training on nurses' job burnout.Methods A total of 236 female registered nurses [mean age (27±4) years,and mean employment (17±3) years] were randomly assigned to the intervention group (n=120) and the control group (n=116).The intervention group had 60-minute group psychological intervention,10-minute psychological relaxing exercises and 20-minute progressing muscle relaxing exercises per week for 8 weeks.The control group did not receive any instrument.The participants were assessed at the 1st and 8th week by using the Job Burnout Scale.Results There was no statistical significance in three dimensions of the Job Burnout Scale between the two groups at baseline (P＞0.05).However,after the intervention,the intervention group had lower scores of EE (13.62±7.86 vs.19.83±4.89) and DP (5.25±3.27 vs.6.55±3.43) and higher scores of PA (38.28±6.34 vs.32.13±7.06) than the control group (all P＜0.01),and had lower scores of EE (18.92±8.36 vs.13.62±7.86) and DP (6.44±3.56 vs.5.25±3.27) and higher scores of PA (28.39±7.78 vs.38.28 ± 6.34) than baseline (all P＜0.01).The control group showed no significant difference in those parameters before and after the intervention (P＞0.05).In the intervention group,1-9 years employment subgroup had lower scores of EE (13.21±7.32 vs.16.91±5.63) and DP (5.61±4.33 vs.7.80±4.59) and higher scores of PA (36.34±7.28 vs.31.39±6.88) than the control group; 10-19 years employment subgroup had lower scores of EE (11.68±5.95 vs.15.14±6.43) and DP (5.11±3.65 vs.7.82±5.21) and higher scores of PA (31.24±8.90 vs.27.33±5.96) than the control group (all P＜0.01); 20-29 years employment subgroup had lower scores of EE (12.37±5.23 vs.15.36±4.98) than the control group (P＜0.01).Conclusions Group psychological intervention and relaxation training could effectively relieve nurses' job burnout.

Cancer-related fatigue (CRF) is associated with tumor and (or) anti-tumor treatment,which has a high incidence and seriously affects the life quality of patients.The etiology of CRF involves psychology,physiology and social factors.There are various hypothesis of pathogenesis and the inflammatory system may play an important role in the generation and development of CRF.A variety of inflammatory cytokines such as IL-1β,IL-6,TNF-α,CRP are significantly correlated with CRF.

Based on special biological characteristics and prognosis, the incidence of gastroesophageal junction adenocarcinoma (GEJA) has rapidly increased over recent years, and its diagnosis and treatment remain controversial. Compared with simple surgery, neo-adjuvant and adjuvant therapies can improve the survival of patients with locally advanced GEJA. Under neo-adjuvant therapy, neo-adjuvant chemoradiation is superior to neo-adjuvant chemotherapy alone for improving the resectability, maintaining loco-regional control, and improving the quality of life of the patient. The combination of this therapy with targeted drugs may further increase the ef-ficacy of GEJA. Most data on GEJA-treated patients were obtained from randomized clinical studies on esophageal cancer or gastric cancer. Thus, prospective randomized controlled studies with a large sample size should be performed to optimize the strategy of neo-adjuvant and adjuvant therapies, and further improve the treatment outcome. In this article, studies on the comprehensive treatment of GEJA were reviewed.

The bacterium Streptomyces peucetius produces doxorubicin and daunorubicin,and the two widely used anticancer antibiotics.Two open reading frames,drrA and drrB,were proposed to encode for an ABC (ATP-binding cassette) type of permease that carries out export of the antibiotic ABC (ATP binding cassette)-type transporter for the exportation of these two antibiotics.In this paper,the structure,expression and interaction of DrrA and DrrB protein and the research progress of the assembly and multi drug efflux function of DrrAB are briefly reviewed.
