Objective: To investigate the level and related factors of humanistic caring ability of psychiatric nurses in a tertiary hospital in Guangzhou. Methods: One hundred and seventy-eight nurses were investigated with Caring Ability Inventory. Results: The score of the caring ability of the investigated nurses was 196.72±16.33. Female nurses scored higher than male nurses in caring ability. The humanistic caring ability of nurse with bachelor degree was higher than that from nursing school(P<0.01). The score of caring ability of nurses with more than 15 years of work experience was significantly higher than others (P<0.01) . The score of humanistic care ability of nurses who are not only children is significantly higher than that of only children (P<0.01) . Conclusion The psychiatric nurses' caring ability needs to be further improved. Gender, only children or not, the professional title, education and working years are the influence factors of humanistic caring ability in psychiatric nursing staff.

Objective:To understand the present situation of occupational benefit and job satisfaction of nurses in Guangzhou medical and nursing institutions, and to analyze the influencing factors of occupational benefit, so as to provide reference for the managers of pension institutions to formulate measures.Methods:A total of 83 in-service nurses from four medical and nursing institutions in Guangzhou were selected by convenient sampling. The general data questionnaire, nurses′ occupational benefit scale, job satisfaction scale, organizational support scale and job input scale were used to adjust the questionnaire.Results:The total score of occupational benefit of nurses in Guangzhou medical and nursing institutions was 106.14±16.38, which was in the middle level. Among them, the score of good nurse-patient relationship (76.40%) was the highest, the score of positive occupational perception(69.20%) was the lowest, and the total score of job satisfaction was 95.25±14.06. Among them, the score of satisfaction with colleagues (76.87%) was the highest, and the score of welfare treatment and professional development opportunity (55.40%, 56.15%) was lower. The total scores of organizational support and work input were 40.18 ± 9.58 and 54.92 ± 9.58, respectively. The results of multiple linear regression showed that nurses′ age, job satisfaction, organizational support and job input were the important factors affecting nurses′ sense of professional benefit( t values were -3.518-6.668, P<0.01 or 0.05). Conclusions:The managers of pension institutions should take positive measures to improve the welfare treatment of nurses, increase their professional development opportunities, strengthen emotional support for nurses, improve nurses′ concentration and energy input to work, so as to improve nurses′ sense of professional benefit and job satisfaction.

ABSTRCT Purpose To explore the evolution of HER2 nega-tive subgroups(IHC Null,Ultra-low and 1+)in breast cancer with hormone receptor(HR)positive before and after neoadju-vant therapy,and the relationship with clinical pathological fea-tures.Methods There were 255 patients who did not achieve pathological complete response(pCR)consecutively after neoad-juvant therapy.Immunohistochemistry was used to detect the ex-pression of ER,PR,HER2 and Ki67 and to evaluate the evolu-tion of HER2-negative subgroups after neoadjuvant therapy and its relationship with clinicopathological characteristics.Results Among the 255 patients included in this study,HER2 expression was 0 and 1+in 116 cases(45.5％)and 139 cases(54.7％)respectively before neoadjuvant therapy,and then HER2 0 was further divided into Null group(61 cases,23.9％)and Ultra-low group(55 cases,21.6％).After neoadjuvant therapy,HER2 expression was 0 and 1+in 117 cases(45.9％)and 138 cases(54.1％)respectively,and then HER2 0 was further di-vided into Null group(64 cases,25.1％)and Ultra-low group(53 cases,20.8％).HER2 status changed in 121 patients(47.5％)after neoadjuvant therapy.The highest conversion rate was from HER2 Ultra-low before neoadjuvant therapy to 1+after neoadjuvant therapy,with a conversion rate of 11.76％(30/255),followed by HER2 1+to the Ultra-low,with a conversion rate of 10.98％(28/255).After the neoadjuvant therapy,44 of 55 cases had transformation in the HER2 Ultra-low group,with the conversion rate of as high as 80％.Chi-square test showed that HER2 expression before neoadjuvant therapy was correlated with the maximum tumor diameter(≤2 cm,＞2cm)after neo-adjuvant therapy(x2=6.106,P=0.047);the tumor of HER21+before neoadjuvant therapy was mostly 2 cm or less in the di-ameter.The HER2 status after neoadjuvant therapy was correla-ted with the tumor thrombus(x2=6.975,P=0.029).Patients with HER2 Ultra-low after treatment were more likely to have vascular invasion.Conclusion In HR positive breast cancer,when the HER2 0 cases are divided into Ultra-low and Null sub-groups,the HER2 conversion rate increases significantly after neoadjuvant therapy,in which the Ultra-low conversion rate is the highest,indicating that the HER2 Ultra-low cases are highly unstable after neoadjuvant therapy.It is important to detect HER2 expression in residual lesions after neoadjuvant therapy and to identify the Ultra-low HER2 expression subgroup.

Peritoneal dialysis, as an important renal replacement therapy for end-stage renal disease patients, can be treated at home. The importance of social support for peritoneal dialysis patients has been widely recognized by researchers. However, due to various reasons, the role of social support has not been fully played. This paper reviews the social support evaluation tools, current situation and influencing factors of peritoneal dialysis patients, summarizes the social support interventions and the existing deficiencies, in order to provide a reference for managers to formulate targeted social support interventions.

Objective:To review the incidence and treatment status of perioperative anemia in patients with gastric cancer.Methods:The clinicopathological data of gastric cancer patients who underwent surgery at Department of Gastrointestinal Surgery, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from Jan to Dec 2019 were collected. Univariate analysis and multivariate Logistic regression analysis were used to explore the risk factors of preoperative anemia in gastric cancer.Results:A total of 879 patients were included in this study. The incidence of preoperative anemia in patients with gastric cancer was 35.6%. The incidence of postoperative anemia was 63.5%. The proportion of patients with preoperative anemia receiving treatment was 17.3%, and the proportion of patients with postoperative anemia receiving treatment was 17.4%. Univariate analysis showed that age, nutritional risk screening 2002, T stage, M stage, tumor stage and lymph node metastasis were associated with preoperative anemia (all P<0.05). Multivariate Logistic regression analysis showed that age >60 years , nutritional risk screening 2002 ≥3, T 3-4 stage and M 1 stage were independent risk factors for preoperative anemia in patients with gastric cancer (all P<0.05). Conclusions:The incidence of perioperative anemia in patients with gastric cancer is high. At present, the proportion of patients with perioperative anemia receiving treatment is low. High nutritional risk, advanced age, late tumor T stage and distant metastasis are independent risk factors for preoperative anemia in patients with gastric cancer.

Objective:To evaluate the clinical outcomes of additional surgery after non-curative endoscopic submucosal dissection (ESD) for early gastric cancer.Methods:Sixty-nine patients with early gastric cancer who underwent ESD and were diagnosed as having non-curative resection by postoperative pathology at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2014 to December 2020 were included in the retrospective observation. Patients were divided into the additional surgery group ( n=12) and the follow-up group ( n=57). The differences in clinical and pathological data of the two groups, the surgical outcomes of the additional surgery group, three-year recurrence-free survival and tumor-specific survival of the two groups, and the independent risk factors affecting three-year recurrence-free survival in the follow-up group were analyzed. Results:Compared with the follow-up group, the rates of submucosal infiltration [66.7% (8/12) VS 21.1% (12/57), χ 2=7.927, P=0.005], vascular invasion [33.3% (4/12) VS 1.8% (1/57), P=0.003] and nerve invasion [16.7% (2/12) VS 0.0% (0/57), P=0.028] in the additional surgery group were significantly higher. In the additional surgery group, the interval between the additional surgery and ESD was 18.5 d (7-55 d), the surgical time was 286.4±85.9 min, and the number of dissected lymph nodes was 25.6±7.4. Four patients (33.3%) had residual tumor. Postoperative complications occurred in 4 patients (33.3%) (all were discharged after conservative treatment), and there was no perioperative death. One patient developed liver metastases 17 months after the surgery, and died 22 months after surgery due to liver metastases. One patient died 22 months after surgery due to non-tumor causes. The three-year recurrence-free survival and three-year tumor-specific survival in additional surgery group were 91.7% (11/12) and 91.7% (11/12), respectively, and those in the follow-up group were 87.7% (50/57) and 100.0% (57/57), respectively. Multivariate Cox regression analysis showed that tumor size ≥2 cm was an independent risk factor for three-year recurrence-free survival in the follow-up group ( P=0.037, HR=15.595, 95% CI: 1.181-205.952). Conclusion:Additional surgery and close follow-up are safe and feasible therapeutic strategies for early gastric cancer patients who underwent non-curative ESD. Clinicians should make reasonable choice based on the pathological results, patients' physical condition and surgery intention. But for patients with primary tumor size ≥2 cm, additional surgery is recommended.
