Objective:To investigate the clinical efficacy of elderly patients with diffuse large B-cell lymphoma (DLBCL) and the influencing factors of prognosis.Methods:The clinical data of 76 elderly (≥60 years old) patients with DLBCL admitted to Huadong Hospital Affiliated to Fudan University between January 2015 and December 2019 were retrospectively analyzed. The R-CHOP regimen was the preferred treatment for 54 patients, while the remaining patients received R-miniCHOP, CHOP or other regimens or supportive treatments due to age, physical condition, economic factors, etc., which were not included in the efficacy analysis. Kaplan-Meier method was used to analyze the survival status of patients. Multivariate Cox proportional risk model was used to analyze the prognostic factors.Results:Among the 54 patients who preferred R-CHOP regimen for treatment, 26 cases (48.1%) achieved complete remission and 14 cases (25.9%) achieved partial remission, and the total effective rate was 74.1% (40/54); Among them, the total effective rate of 37 cases aged 60-69 years was 70.3% (26/37), and the total effective rate of 17 cases aged 70-79 years was 82.4% (14/17); there was no statistically significant difference in the total effective rate between the two groups ( χ2 = 3.01, P = 0.390). All 76 patients were followed up for 1-60 months. As of the last follow-up, 49 patients (64.5%) died, with the median overall survival (OS) time of 16 months and 5-year OS rate of 35.5%. Kaplan-Meier method showed that age ≥ 70 years old at initial diagnosis, Eastern Cooperative Oncology Group (ECOG) score ≥ 2 points, presence of B symptoms, international prognosis index (IPI) score >3 points, elevated lactate dehydrogenase, immunohistochemistry positive for bcl-2, and non-germinal center type were associated with poor OS (all P < 0.05). Multivariate Cox analysis showed that age ≥ 70 years old at initial diagnosis, presence of B symptoms, positive expression of bcl-2, non-germinal center type were independent risk factors for OS (all P < 0.05). Conclusions:Elderly DLBCL patients have poor survival. Old age at initial diagnosis, B symptoms, bcl-2 positive, and non-germinal center type are independent risk factors of prognosis.

Objective:To explore the professional quality learning needs among nursing students in colleges and universities in China under the background of the five educations.Methods:Convenience sampling was used to select nursing students who interned at Chinese Academy of Medical Sciences & Peking Union Medical College Hospital in 2021 as the research subject. The survey was conducted using a self-made "Professional Quality Learning Needs among Nursing Students in Colleges and Universities ". Multiple linear regression was used to explore the influencing factors of nursing students' professional quality learning needs. A total of 349 questionnaires were distributed, and 348 valid questionnaires were collected, with an effective recovery rate of 99.7%.Results:Among 348 nursing students, the five items with the highest need for professional quality learning were basic nursing skills, correct implementation of nursing procedures, communicating with patients and their families in appropriate ways, understanding of patient safety related concepts and nursing professional knowledge. Academic degree was a factor that affected the professional quality learning needs among nursing students ( P<0.05) . Conclusions:The training of nursing students' professional quality should be need oriented and establish a new era of "five education" concept. It should not only meet job requirements, but also combine students' own characteristics and growth patterns to cultivate nursing talents that meet clinical needs.

Objective:To investigate the clinical safety of daratumumab (DARA) in patients with relapsed/refractory multiple myeloma (MM).Methods:The diagnosis and treatment process of 2 cases of relapsed/refractory MM treated in Huadong Hospital of Fudan University in 2020 were retrospectively analyzed, the related laboratory indicators indexes after using DARA were analyzed, and the related literature was reviewed.Results:After using DARA, the 2 patients rapidly developed tumor lysis syndrome (TLS) such as high potassium, high phosphorus, high uric acid, low calcium and kidney damage, which eventually led to the death of patients.Conclusions:Patients with high tumor load treated by DARA are prone to TLS, which is often life-threatening. Clinicians should be alert to the occurrence of such events.

Objective:To establish the norm of the Chinese version of Karitane Parenting Confidence Scale (KPCS) in urban areas of China.Methods:From August to December 2017, the parents of 2 216 children (<36 months old) were selected from 15 cities (Beijing, Lianyungang, Hangzhou, Chengdu, Xi′an, Guangzhou, Changsha, Jinan, Guiyang, Ningbo, Dalian, Qinhuangdao, Maanshan, Chongqing and Wuhan) in 14 provinces by stratified random sampling. The general demographic characteristics and parents′ parenting confidence were collected by a self-made questionnaire and KPCS Chinese version. The percentile norm was established. P 3, P10 and P 25 were used as the criteria to define the degree of lack of parenting confidence. Results:The age of mothers was (30.67±4.29). The age of the father was (32.50±4.99) years old. There were 726 (32.76%), 759 (34.25%) and 731 (32.99%) infants in 6-12, 12-23 and 24-35 months old groups. The total scores of P 50, P 25, P 10 and P 3 of KPCS (Chinese version) of infant parents in urban areas in China were 41, 38, 33, and 29 respectively. When the scores of parents were 34-37, 30-33, and ≤ 29, they were judged as mild, moderate, and severe lack of parenting confidence. There was no significant difference in the Chinese version of KPCS between parents of different age groups and parents of different gender (χ2=3.53, P=0.171; χ2=1.41, P=0.236). Each factor score≤ P 3 is defined as the boundary score, and the corresponding boundary scores of "parenting" "support" and "competence" were 13, 9, and 5 respectively. Conclusion:The Chinese version of KPCS can be used to assess the parenting confidence of infants in urban areas of China. It can used as one of the bases for scientific and objective evaluation of the parenting status of families.

Objective:To investigate the clinical features and effect of prognostic factors in patients with different pathological types of non-Hodgkin lymphoma-associated hemophagocytic lymphohistiocytosis.Methods:We collected and analyzed the clinical data of 89 patients with non-Hodgkin lymphoma-associated hemophagocytic lymphohistiocytosis who were treated at Huadong Hospital from March 2013 to May 2020. The data were analyzed via log-rank and Cox multivariate analyses.Results:The median overall survival time of the 89 cases was 10.2 months. Patients with B-cell lymphoma-associated hemophagocytic lymphohistiocytosis did not reach the median overall survival time. The median overall survival times of T-cell lymphoma-associated hemophagocytic lymphohistiocytosis and NK-cell lymphoma-associated hemophagocytic lymphohistiocytosis were 10.2 and 3.0 months, respectively. The pathological type of non-Hodgkin lymphoma (OS: P=0041, PFS: P=0.015) , ECOG score ≥ 3 (OS: P=0.031, PFS: P=0.030) , hematopoietic stem cell transplantation (OS: P=0.005, PFS: P=0.040) , lymphadenopathy (OS: P=0.007, PFS: P=0.012) , and splenomegaly (OS: P=0.276, PFS: P=0.324) were related to the overall survival and progression-free survival of patients with non-Hodgkin lymphoma-associated hemophagocytic lymphohistiocytosis. Splenectomy could improve the prognosis of patients with lymphoma-associated hemophagocytic lymphohistiocytosis, especially T-cell lymphoma-associated hemophagocytic lymphohistiocytosis. Conclusion:The clinical characteristics of patients with different pathological types of non-Hodgkin lymphoma-associated hemophagocytic lymphohistiocytosis were similar but were different in the overall survival rate and the effect of prognostic factors. We suggested that patients with non-Hodgkin lymphoma-associated hemophagocytic lymphohistiocytosis should receive more than combined chemotherapy. To improve the prognosis and survival rate of patients, those with B-cell lymphoma-associated hemophagocytic lymphohistiocytosis and NK-cell lymphoma-associated hemophagocytic lymphohistiocytosis promptly require hematopoietic stem cell transplantation. Moreover, patients with T-cell lymphoma-associated hemophagocytic lymphohistiocytosis should consider splenectomy.

Objective: To explore the relationship between physiological parameters changes and severe heatstroke induced by 5-km armed cross-country training. Methods: A total of 521 male officers and soldiers from a special team who participated in the summer training of 5-km armed cross-country training from year 2016 to 2017 were enrolled. All trainees participated in 5-km armed cross-country training in high temperature and humidity environment of ambient temperature > 32 ℃and (or) relative humidity > 65%. The trainees were divided into two groups according to the incidence of severe heatstroke in the course of training. The age, enlistment time, constitution score, body mass index (BMI), external environment (ambient temperature, relative humidity, wind speed, heat index) of trainees of the two groups, and the change rates of arterial blood oxygen saturation (SaO₂), body temperature, pulse and blood pressure within 5 minutes after the 5-km armed cross-country training were compared between the two groups. The risk factors of severe heatstroke were screened by two classified Logistic regression analysis, and the predictive value of various risk factors of severe heatstroke was analyzed by the receiver operator characteristic curve (ROC). Results: In 521 trainees of 5-km armed cross-country training, 29 trainees suffered from severe heatstroke accounting for 5.57%. There was no significant difference in the age, enlistment time, constitution score, BMI, or external environment during 5-km armed cross-country training between severe heatstroke group and non-severe heatstroke group. Compared with those without severe heatstroke, the descending rates of body temperature, pulse, blood pressure and SaO₂ increased rate within 5 minutes after 5-km armed cross-country training of severe heatstroke trainees were significantly decreased [temperature descending rate: (0.67±0.30)% vs. (1.43±1.28)%, pulse descending rate: (7.53±5.21)% vs. (13.48±8.07)%, blood pressure descending rate: (9.28±6.84)% vs. (19.42±7.73)%, SaO₂ increased rate: (0.51±0.39)% vs. (1.50±1.43)%, all P < 0.01]. Two classification Logistic regression analysis showed that the temperature descending rate [odds ratio (OR) = 0.485, 95% confidence interval (95%CI) = 0.289-0.817], pulse descending rate (OR = 0.903, 95%CI = 0.845-0.965), blood pressure descending rate (OR = 0.841, 95%CI = 0.790-0.896), and SaO₂ increased rate (OR = 0.421, 95%CI = 0.250-0.711) were the risk factors for severe heatstroke during 5-km armed cross-country training (all P < 0.01). ROC curve analysis showed that temperature descending rate [area under ROC curve (AUC) = 0.659, 95%CI = 0.604-0.714], pulse descending rate (AUC = 0.730, 95%CI = 0.762-0.900), blood pressure descending rate (AUC = 0.831, 95%CI = 0.659-0.801), SaO₂ increased rate (AUC = 0.711, 95%CI = 0.655-0.767) could be used for the incidence of severe heatstroke prediction during 5-km armed cross-country training (all P < 0.01), and the predicted value was the same. Conclusions Under the same conditions, the severe heatstroke during 5-km cross-country training is closely related to the descending rates of body temperature, pulse, and blood pressure as well as SaO₂ increased rate within 5 minutes after the training, whose predictive values for severe heatstroke were the same.
