Objective:To investigate the current status of breast reconstruction after breast cancer surgery in hospitals in China.Methods:This study was a cross-sectional study using convenience sampling. A self-designed survey questionnaire was used to investigate nurses of department of breast diseases in China from May to August 2023. The content of the questionnaire included four aspects: identification information, basic hospital information, the implementation situation of breast reconstruction after breast cancer surgery, and the situation of medical and nursing human resources for breast reconstruction, with a total of 39 items. Statistical analysis was performed using SPSS 26.0 software. The non-normally distributed measurement data were expressed as M( Q1, Q3), and the Mann-Whitney U test was used for comparison between groups. Numeric data were expressed as frequency and percentage, and comparisons between groups were made using the χ2-test or Fisher’s exact probability method. P<0.05 indicated that the difference was statistically significant. Results:A total of 212 public hospitals from 31 provinces, autonomous regions and municipalities participated in the survey. Two hundred and three hospitals (95.8%) returned valid data, including 155 Grade Ⅲ Level A hospitals, 19 Grade Ⅲ Level B and C hospitals, and 29 Grade Ⅱ hospitals. There were 157 general hospitals, 32 specialized cancer hospitals, and 14 other hospitals. Thirty-nine hospitals did not perform breast reconstruction surgery. A total of 164 hospitals (80.8%) had already carried out breast reconstruction surgery, among which the proportion of breast reconstruction in Grade Ⅲ Level A hospitals [90.3% (140/155)] was significantly higher than that in Grade Ⅲ Level B and C hospitals [52.6% (10/19)] and Grade Ⅱ hospitals [48.3% (14/29)] ( P<0.01). The proportion of breast reconstruction in specialized cancer hospitals [96.9% (31/32)] was significantly higher than that in general hospitals [79.0% (124/157)] and other types of hospitals [64.3% (9/14)] ( P<0.05). Among the 164 hospitals, 310 (150, 637.5) patients underwent breast cancer surgery and 30 (10, 100) patients underwent breast reconstruction in 2022. The proportion of patients undergoing breast reconstruction surgery among breast cancer surgery patients was 13.3% (4.0%, 20.0%). The number of patients receiving immediate breast reconstruction was 11 (2.5, 46.5) cases, and the number of those receiving delayed breast reconstruction was 5 (0, 18.5) cases. Among 203 hospitals, the median proportions of breast oncoplastic surgeons and specialized nurses among healthcare providers in breast surgery departments were 28.6% (2/7) and 75.0% (12/16), respectively. In comparison of the 164 hospitals offering breast reconstruction surgery and 39 hospitals not, the median numbers of breast oncoplastic surgeons were 3 (1, 8) versus 1 (0, 3), and qualified breast reconstruction nurses were 12 (6, 16) versus 1 (0, 8), respectively. All differences were statistically significant (all P<0.01). Conclusion:About 80% of hospitals in China have offered breast reconstruction procedures after breast cancer surgery, and the proportion of Grade Ⅲ Level A hospitals and specialized cancer hospitals is higher than that of other types of hospitals. The proportion of patients undergoing breast reconstruction after breast cancer surgery is relatively low, and there is a considerable potential of improvements. Breast oncoplastic surgeons and nurses are insufficient, so it is necessary to strengthen the training of specialized medical staff and improve surgical techniques and the level of nursing services simultaneously, so as to improve the quality of life of breast cancer patients.

Objective:To explore influencing factors of the occurrence of fear of disease progression (FoP) in stroke patients and to construct a risk prediction nomogram model.Methods:A total of 201 stroke patients of the First Affiliated Hospital of Qiqihar Medical University and the Third Affiliated Hospital of Qiqihar Medical University from July to December 2023 were selected as the survey objects by the convenient sampling method. Baseline data questionnaire, Fear of Progression Questionnaire-Short Form (FoP-Q-SF), Chinese version of Perceived Stress Scale (CPSS), Social Support Rating Scale (SSRS) and Fatigue Severity Scale (FSS) were used to investigate of patients FoP occurrence, stress perception, social support level and fatigue level of stroke patients. The influencing factors of FoP occurrence in stroke patients were explored and R 4.3.2 was used to construct a risk prediction nomogram model for FoP occurrence in stroke patients. The performance of the model was evaluated using receiver operating characteristic curve, calibration curve, and clinical decision curve from the perspectives of discrimination, calibration and clinical practicality.Results:In this study, a total of 201 questionnaires were collected, 199 were valid, and the effective rate was 99%. The FOP-Q-SF score of 199 patients was (29.64±9.50), of which 71 patients (35.7%) developed FoP. Educational level, complications, self-care ability, social support, stress perception and fatigue were the influencing factors of FoP in stroke patients ( P<0.05). A risk prediction nomogram model for FoP in stroke patients was constructed based on the results of binary Logistic regression analysis. The Hosmer-Lemeshow results showed that the nomogram model fitted well (χ 2=10.466, P=0.234). The area under ROC curve was 0.912 (95% CI: 0.871-0.952). The clinical decision curve showed that when the threshold probability ranged from 4% to 99%, choosing this model to predict the risk of FoP could benefit stroke clinically. Conclusions:Educational level, complications, self-care ability, social support, stress perception and fatigue are the influencing factors for fear of disease progression in stroke patients. The risk nomogram model based on multiple evaluation indexes has certain clinical value.

Objective To explore the current status of clinical inertia in the treatment of patients with type 2 diabetes mellitus (T2DM) in the suburbs of Shanghai and analyze its risk factors. Methods A total of 1, 804 T2DM patients who visited the Endocrinology and Metabolism Clinic of Shanghai Sixth People's Hospital from November 2022 to November 2023 were selected as research objects. Patients were divided into clinical inertia group and non-clinical inertia group based on whether clinical inertia occurred during their treatment, and demographic and clinical data were collected. Logistic regression analysis was used to identify risk factors for clinical inertia in the treatment of T2DM patients. Results The incidence of clinical inertia in T2DM patients was 52.00% (938/1, 804). The results of multivariate Logistic regression analysis showed that longer diabetes duration, high level of glycated hemoglobin (HbA1c), high score of the Problem Areas in Diabetes Scale(PAID) score, taking over two oral medications, shorter life expectancy, and coexisting retinopathy were risk factors for clinical inertia in the treatment of T2DM patients (P < 0.05). Conclusion The incidence of clinical inertia is high in T2DM patients during treatment in the suburbs of Shanghai. T2DM patients with poor glycemic control, longer disease duration, high level of psychological distress, taking over two oral medications, shorter life expectancy, and coexisting retinopathy are more prone to occur clinical inertia.

Objective:To explore the effect of small private online course (SPOC) in basic nursing course teaching.Methods:In September 2019, convenience sampling was used to select 150 second-year nursing undergraduates of the 2018 grade from the School of Nursing, Qiqihar Medical College, as the research subject. This study relied on the Chaoxing learning platform to build a SOPC-based pre-class + in-class + after-class blended teaching model, and evaluated the implementation effect.Results:Among 150 students, the online learning score was (93.13±7.76) , and the final offline examination score was (85.61±10.09) . The number of visits to the online platform was 9 428 person-times, a total of 55 topics were discussed by teachers and students, and 172 task points were completed. In the evaluation of each item of the teaching effect of basic nursing based on SPOC by 150 students, more than 80% of students strongly agreed and agreed, and there was no evaluation that strongly disagreed.Conclusions:The SPOC-based teaching model is applied to the teaching of basic nursing courses, which can meet the learning needs of students and improve the quality of education and teaching.

Objective? To understand the current situation and requirements of core competence post training for community nurses in Qiqihar City, and to provide references for improving the content and methods of core competence post training for community nurses. Methods? By convenience sampling, 394 community nurses working in 65 community health service organizations in 7 district of Qiqihar city were selected from September to December of 2018. Community Nurse Core Competence Rating Scale(CNCCRS) and self-designed questionnaire were used to investigate the position training status and needs. The t test, chi-square analysis were adopted to analyze and compare the score and each dimensional score in CNCCRS for different training with different position features, and to statistically describe the needs of community nurses' core competence post training. Results? The total score of CNCCRS from those who had received the post training was (145.69± 30.55). There was no significant difference in the total score of CNCCRS and the scores of each dimension between nurses who had participated in nursing related training or not (P＞ 0.05); there were significant differences in the total score of CNCCRS and the scores of each dimension among nurses who had participated in different modes of training (P＜0.05). The most preferred mode of training for the nurses was in-service short online courses through initiative learning. Conclusions? The core competence of community nurses in Qiqihar City who have training experience is still at the medium level, and the training has not achieved the expected outcome. It is suggested that short-term on-the-job and online independent training combining theory and practice should be carried out according to the particular needs of community nurses in the future.

Objective To retrieve and analyze the evidences on insulin injection position selection and rotation in patients with diabetes, and to summary the best evidence. MethodsWe took "diabetes mellitus""insulin" "injection" "position" "rotation" as subject terms to retrieve the evidences on insulin injection position selection and rotation in the evidence-based database such as the British Medical Journal (BMJ) best practice, Uptodata, Cochrane Library (2014), Joanna Briggs Institute Library, Registered Nurses' Association of Ontario (RNAO), Scottish Intercollegiate Guidelines Network (SIGN) and National Guideline Clearinghouse (NGC) as well as the comprehensive database such as the Embase, Elsevier science Direct, PubMed, Web of Science, OVID, China Biological Medicine (CBM) and WanFang data. ResultsA total of 13 evidences were included, 2 evidence summaries, 7 guidelines and 4 consensus. Four kinds of evidence were summarized including training for insulin standardized injection and management, evaluation, injection position and rotation. ConclusionsMedical staff should standardize the clinical practice behavior in insulin injection position selection and rotation based on relevant levels of evidence-based medicine to guarantee the safety of patient and improve quality of nursing.

Objective: To investigate the clinical significance of tumor associated macrophages (TAM) in multiple myeloma (MM) and the relationship with angiogenesis and immunosuppression. Methods: Seventy cases of MM patients diagnosed from August 2015 to June 2017 were enrolled in the study as experimental group, 20 cases of benign hematological diseases (13 with iron deficiency anemia and 7 with megaloblastic anemia) patients as control group. Immunohistochemical method was used to detect the expression of CD163, CD34 and VEGF in bone marrow samples, and flow cytometry was used to detect the proportion of regulatory T cell (Treg cells), ELISA was used to detect the level of IL-10, and the clinical features were analyzed. Results: ①Among the 70 patients, there were 31 males and 39 females with a median age of 65 (50~78) years old. TAM infiltration density, microvascular density (MVD), VEGF expression level, Treg ratio and IL-10 level in bone marrow samples of 70 MM patients were significantly higher than those of benign hematological diseases (P<0.05). ②In the MM group, the above indexes of the patients with disease stabilized (15 cases) were lower than those of the newly diagnosed group (35 cases) and the relapse refractory group (20 cases) (P<0.05), those of relapse refractory group were higher than those of newly diagnosed group (P>0.05). ③Of the 35 newly diagnosed MM patients, 27 completed 4 courses of treatment. In the effective group (15 cases), the TAM infiltration density after treatment was significantly lower than that before treatment, the difference was statistically significant[(20.20±7.66) vs (28.87±11.97), t=2.362, P=0.025]; while in the ineffective group of 12 cases, the difference of the TAM infiltration density before and after treatment was not statistically significant[(42.00±13.76) vs (48.25±13.59), t=1.119, P=0.275]. ④TAM infiltration density in the effective group after bortezomib treatment (21 cases) were lower than those in the non-bortezomib treatment group (18 cases)[(16.52 ±4.26) vs (19.27 ±5.82), t=1.662, P=0.170]. ⑤The TAM infiltration density in MM patients was positively correlated with MVD, VEGF expression level, Treg cell ratio and IL-10 level (P<0.001). Conclusion The infiltration of TAM in the microenvironment of MM, which may promoting angiogenesis and inhibiting immune response, is related to the occurrence, development, therapeutic effect and drug resistance of MM.

Purpose To investigate the clinicopathological characteristics,diagnosis and differential diagnosis of benign metastasizing leiomyoma (BML).Methods The clinicopathological data in 6 patients with BML were collected.All cases of BLM were investigated by HE and immunohistochemistry of EnVision method.Results All cases were female,with age of 33 -65 years,and had undergone myomectomy.5 cases had lung metastasis,including abdominal wall metastasis and spinal metastasis in each of the 1 cases,and another case had inguinal metastasis.Morphology showed that the tumor cells were spindle without obvious atypia,nuclear mitoses and necrosis,some cases were cellular.Immunohistochemical staining showed that the tumor cells were positive for SMA,SM-MHC,desmin,ER,PR,vimentin,while negative for S-100,CD117,CD34.Ki-67 label index were less than 5％.3 patients were alive with tumor and 3 patients were alive without tumor in the follow up of 18,28,40,31,36,80 months.Conclusion BML often occurs in female patients that undergone uterine myomectomy.The lung is the most common site of metastasis,often accompanied by other sites.The disease progresses slowly,and most patients have a longer survival time.

Objective:To explore the pharmaceutical care approaches for the patients with early breast cancer secondary osteoporo-sis treated with letrozole. Methods:A patient with early breast cancer treated with letrozole in long-term faced the high risk of second-ary osteoporosis and led to fracture. How to reduce the risk of fractures by using drugs was the breakthrough point of clinical pharma-cists, and then, individualized pharmaceutical care was performed. Results: The patient was assessed at high risk of fractures in 10 years, and clinical pharmacists assisted doctors to optimize drug therapy, and carried out long-term follow-up education to the patient. The waist pain of the patient disappeared in six months. Conclusion: For early breast cancer patients treated with letrozole, clinical pharmacists should consider the diet and living habits of the patients, assess the fracture risk in 10 years, adjust individual dose of cal-cium and vitamin D3 , choose appropriate bone absorption inhibitors and endocrine treatment, and perform follow-up for the long-term treatment compliance of the patients.
