Bibliometric analysis of research related to medical humanistic care based / 中国医学伦理学

ObjectiveBy analyzing the research related to medical humanistic care， the aim is to understand its research status and development trends， and provide theoretical and data support for research in this field. MethodsThe relevant literature in the China National Knowledge Infrastructure （CNKI） database were systematically searched. Excel 2019 was used to analyze the situation of annual publication volume， journal distribution， and other content of the literature. CiteSpace software was used to visually analyze the knowledge graph related to authors and keywords. ResultsA total of 825 articles were included in the study and the overall number of articles showed an upward trend since 2000. The research hotspots included humanistic care， medical humanities， nursing education， etc. It was found by analyzing that there were three problems in the research of humanistic care in medicine：the research focus is mainly on the need for medical staff to provide patients with more humanistic care， and there is relatively little research on the humanistic care of medical staff themselves；The types of journals are scattered， and the funding support is insufficient；No medical education collaborative research model has been formed. ConclusionMedical humanistic care is the essence of the professional spirit of physicians and an important indicator in testing the effectiveness of medical humanistic education. In the future， the research on medical humanistic care should strengthen multi-dimensional humanistic care to effectively protect the rights and interests of medical staff， pay more attention to the combination of theoretical research and clinical practice， exploit the instrumental value of narrative medicine， increase support efforts from fund， and improve top-level design.

Analysis of related factors and prediction of poor ovarian response in patients with controlled ovarian stimulation / 中华妇产科杂志

Objective:To explore the related factors of poor ovarian response (POR) in patients receiving controlled ovarian stimulation (COS) and to establish the nomogram for predicting POR in patients who received in vitro fertilization or intracytoplasmic sperm injection (IVF/ICSI).Methods:In this retrospective research, clinical data of 17 164 cycles of patients who received IVF/ICSI treatment at Henan Provincial People′s Hospital from September 1st, 2016 to September 1st, 2020 were analyzed. Independent correlative factors affecting the occurrence of POR were screened by logistic regression, which were the model enrollment variables in the prediction model. Totally 13 266 cycles with well-record of enrollment variables were screened, and these data were randomly divided into model group (9 896 patients) and validation group (3 370 patients) according to 3∶1. The nomogram was established according to the regression coefficient of the relevant variables. The prediction accuracy of the nomogram was evaluated by calculating area under the receiver operating characteristic curve (AUC).Results:Multivariate logistic regression analysis showed age, infertility type, body mass index, anti-Müllerian hormone, basal follicle stimulating hormone, basal estrogen, antral follicle number, previous times of POR, history of ovarian surgery, ovulation stimulation protocol and average amount of gonadotropin were independent correlative factors affecting the occurrence of POR (all P<0.05). In the model group, according to the above factors, the prediction model and nomogram of POR risk were constructed and the validation group verified the model. The AUC of the model group was 0.893 (95% CI: 0.885-0.900), and the AUC of the validation group was 0.890 (95% CI: 0.878-0.903). Conclusion:The influencing factors of POR after COS in patients treated by IVF/ICSI are screened, and the nomogram for predicting POR established in this study is proved to be effective, simple, intuitive and clear in predicting the occurrence of POR.

Study on the perception and influencing factors of retirement service among the elderly in the community-conprehensive care service complex / 中华健康管理学杂志

Objective:To analyze the willingness of elderly individuals from a certain community to choose different retirement care methods and factors influencing this in the community-embedded elderly care service complex.Methods:Stratified variable ratio sampling was used to select 500 elderly people from a certain community in Guangzhou. A self-developed questionnaire regarding willingness to choose retirement care in the community-embedded elderly care service complex was administered. Data were analyzed by multi-category logistic regression analysis.Results:Among the services involved in the community-embedded elderly care service complex, 57.6%, 31.2%, and 11.2% of the elderly selected family, community home, and institution care, respectively. Logistic regression analysis showed that seniors with college degrees or above ( OR=2.514), who were cared for by family ( OR=3.345), with a monthly income of 3 000-5 000 yuan ( OR=1.891), with monthly pension payments of 1 000-3 000 yuan ( OR=2.572), or with average health status ( OR=3.716) were more willing to choose community based retirement services (all P<0.05). Meanwhile, seniors with a better occupation before retirement ( OR=9.813), a monthly income of 3 000-5 000 yuan ( OR=3.222), monthly pension payment above 3 000 yuan ( OR=6.902), poor health status ( OR=1.000), or who were unattended ( OR=4.386) were more inclined to choose community institution care (all P<0.05). Conclusion:The elderly still rely mainly on family based retirement life, but their willingness to use socialized retirement is more prevalent. Educational level, occupation, economic status, caregivers, and health status are the main factors affecting the elderly′s choice of different pension methods in the community-embedded elderly care service complex.

Analysis of clinical and pathological characteristics of 266 cases of colorectal laterally spreading tumor / 中华消化杂志

Objective:To analyze the clinical and pathological characteristics of colorectal laterally spreading tumor (CLST) and provide reference for clinical diagnosis and treatment of CLST.Methods:From January 1, 2016 to June 30, 2021, the clinical data of patients with CLST who underwent endoscopic resection at the Second Affiliated Hospital of Dalian Medical University were retrospectively collected. The clinical and pathological characteristics of CLST were analyzed in terms of lesion location (right colon, left colon, rectum) and morphological type (granular-homogeneous type, granular-mixed type, flat-elevated type, and pseudo-depressed type). One-way analysis of variance, Pearson′s chi-square test and Fisher′s exact test were used for statistical analysis.Results:A total of 266 patients with CLST and 296 CLST lesions were included. The most common maximum diameters of the lesions were 10 to 29 mm, accounting for 85.1% (252/296). The main morphological type was granular type, accounting for 81.4% (241/296), and the main pathological type was adenoma, accounting for 79.7% (236/296), and the most common histological type was low-grade intraepithelial neoplasia (LGIN), accounting for 81.1% (240/296). The maximum diameter of CLST lesion of rectum was larger than that of the right colon and the left colon ((24.20±16.97), (18.38±8.24) and (18.59±7.95) mm, respectively), and the difference was statistically significant ( F=6.62, P<0.001). The detection rate of granular-homogeneous type CLST in rectum was lower than that in the right colon and the left colon (22.0%, 11/50, 53.5%, 69/129 and 58.9%, 69/117, respectively), while the detection rate of granular-mixed type CLST in rectum was higher than that in the right colon and the left colon (50.0%, 25/50; 29.4%, 38/129 and 24.8%, 29/117, respectively), and the differences were statistically significant ( χ2=20.06 and 10.67, both P<0.01). The incidence of adenoma in CLST in the right colon was lower than that in the left colon and rectum (68.2%, 88/129; 87.2%, 102/117 and 92.0%, 46/50, respectively), while the incidence of serrated adenoma in CLST in the right colon was higher than that in the left colon and rectum (30.2%, 39/129; 12.8%, 15/117 and 4.0%, 2/50, respectively), and the differences were statistically significant ( χ2=19.25 and 20.85, both P<0.001). The CLST in left colon was mostly treated by endoscopic submucosa dissection (94.9%, 111/117), while the CLST in rectum was mostly treated by endoscopic mucosal resection (20.0%, 10/50), and the difference was statistically significant ( χ2=8.77, P=0.012). The maximum diameter of the pseudo-depressed type CLST was larger than that of the granular-homogeneous type, granular-mixed type and flat-elevated type ((24.18±14.07), (15.96±5.70), (23.49±13.80) and (21.21±8.02) mm), and the difference was statistically significant ( F=13.40, P<0.001). The incidence of adenoma in flat-elevated type CLST was higher than that of the granular-homogeneous type, granular-mixed type and pseudo-depressed type (92.1%, 35/38; 71.1%, 106/149; 86.9%, 80/92 and 15/17, respectively), and the difference was statistically significant ( χ2=14.13, P=0.003). The incidence of serrated adenoma in the granular-homogeneous type CLST was higher than that of the granular-mixed type, flat-elevated type and pseudo-depressed type (28.9%, 43/149; 10.9%, 10/92; 5.3%, 2/38 and 1/17, respectively), and the difference was statistically significant ( χ2=19.98, P<0.001). The incidence of adenocarcinoma in the pseudo-depressed type CLST was higher than that of the granular-homogeneous type, granular-mixed type and flat-elevated type (1/17; 0, 0/149; 2.2%, 2/92 and 2.6%, 1/38, respectively), and the difference was statistically significant (Fisher′s exact test, P=0.049). The incidence of LGIN in the granular-homogeneous type CLST was higher than that of the granular-mixed type, flat-elevated type and pseudo-depressed type (90.6%, 135/149; 76.1%, 70/92; 65.8%, 25/38 and 10/17, respectively), while the incidences of high-grade intraepithelial neoplasia and carcinoma in the pseudo-depressed type CLST were higher than those of the granular-homogeneous type, granular-mixed type and flat-elevated type (6/17; 9.4%, 14/149; 21.7%, 20/92; 31.6%, 12/38 and 1/17; 0, 0/149; 2.2%, 2/92 and 2.6%, 1/38), and the differences were statistically significant( χ2=21.58 and 16.81 and Fisher′s exact test, all P<0.05). Conclusions:The clinicopathological characteristics of CLST have certain specificity. The maximum diameter and malignant potential of the rectal CLST are both larger and higher than those of the colonic CLST. Although the granular-mixed type CLST is the granular type, it shows a larger maximum diameter and a higher degree of malignancy.
