OBJECTIVE To analyze the influential factors for potentially inappropriate medication （PIM） in elderly cancer patients. METHODS The data of elderly cancer patients hospitalized in a hospital from January to December 2021 were collected. According to the Beers standard of the American Geriatrics Society in 2019 （hereinafter referred to as the “2019 version of Beers standard”） and Criteria for Potentially Inappropriate Drug Use in Chinese Elderly （2017 version） （hereinafter referred to as the “Chinese PIM standard”）， the PIM status of elderly cancer patients was retrospectively analyzed. Multivariate Logistic regression analysis was used to identify influential factors for PIM. RESULTS A total of 293 patients were included in the study. According to the 2019 version of Beers standard， 211 patients （72.01%） had PIM， of which 204 （69.62%） had PIM related to drugs， 6 （2.05%） had PIM related to diseases or symptoms， 46 （15.70%） had PIM that should be used with caution， 32 （10.92%） had PIM with drug-drug interaction that should be avoided， and 11 （3.75%） had PIM based on renal function； the top 5 drugs in the list of incidence were proton pump inhibitors， metoclopramide， the first-generation antihistamines as promethazine， analgesics as ibuprofen and megestrol. According to the Chinese PIM standard， there were 132 patients （45.05%） with PIM， of which 119 （40.61%） had PIM related to drugs， involving 25 drugs （included 7 high-risk drugs and 18 low-risk drugs）， and 24 （8.19%） with PIM in disease status； top 4 drugs in the list of incidence were promethazine， megestrol， ibuprofen and cimetidine. Multivariate Logistic regression analysis showed that compared with patients with hospital stay≤10 days， patients with hospital 20054） stay between 11 and 30 days had a higher risk of PIM [odds ratio （OR）＝8.836 8， 95% confidence interval （CI） （3.217 8， 31.940 9）， P＝0.000 1]； compared with the patients with the 65895198。E-mail：fjman@cmpt.ac.cn number of clinical disease diagnosed≤5， patients with the number of clinical disease diagnosed≥11 had a higher risk of PIM [OR＝10.930 1， 95%CI （3.000 9， 70.922 9）， P＝0.001 8]； compared with surgical treatment， patients receiving antineoplastic drugs had a higher risk of PIM [OR＝2.209 5， 95%CI （1.180 2， 4.176 9）， P＝0.013 6]. CONCLUSIONS Elderly cancer patients have multiple diseases， complicated medication， and a high incidence of PIM. The length of hospital stay （11-30 d）， the number of clinical disease diagnosed （≥11） and anti-tumor drugs are main influential factors for PIM in patients.

Objective:To improve the understanding of adult primary hemophagocytic syndrome (HPS) with aggressive natural killer cell leukemia (ANKL).Methods:The clinicopathological data of one adult patient with suspected primary HPS complicated with ANKL in Huiqiao Medical Center, Nanfang Hospital of Southern Medical University in October 2017 were retrospectively analyzed, and literatures were reviewed.Results:A 21-year-old male patient presented with persistent fever, hemocytopenia, splenomegaly, low fibrinogen, a significant increase in ferritin, hemophagocytes in bone marrow, decreased natural killer (NK) cell activity, and increased soluble CD25. Flow cytometry detection showed that the expression of NK cells was abnormal, and there were familial lysosomal trafficking regulator (LYST) and UNC13D gene defects. He was suspected of primary HPS complicated with ANKL. The patient was given 4 courses of EPOCH+PEG-Asp (etoposide, dexamethasone, vindesine, cyclophosphamide, doxorubicin hydrochloride liposome, pegaspargase) regimen chemotherapy, 20 mg of citalopidine twice a week maintenance therapy and matched unrelated hematopoietic stem cell transplantation. After 35 months of follow-up, he got sustained remission.Conclusions:Even if there are secondary causes of adult HPS, it is necessary to screen out related genes to avoid misdiagnosis. HPS patients with ANKL progress rapidly, and the early mortality is high. EPOCH+ PEG-Asp regimen induction therapy and allogeneic hematopoietic stem cell transplantation should be used as early as possible after diagnosis.

Objective:To explore benefit finding and its influencing factors among enterostomy patients.Methods:A total of 120 enterostomy patients were investigated with general information questionnaire, Benefit Finding Scale, Simplified Scale of Resilience and Perceived Social Support Scale.Results:The score of benefit finding among enterostomy patients was 49.44±5.86. Multiple regression analysis showed that education level, self-care, complications, resilience, perceived social support were influencing factors of benefit finding, and explained 51.1% of the variance.Conclusions:The benefit finding among enterostomy patients was grim. It is suggested that clinical staff pay more attention to the patients with low education, poor self-care and complications of stoma, and also pay more attention to the positive psychology and the social support system of patients, guide patients to pay attention to the positive significance of the disease, so as to improve the level of benefit finding.

Objective:To investigate the current situation with regard to a sense of coherence in major caregivers of enterostomy patients and analyze its relationship with self-efficacy and perceived social support.Methods:From July to December 2019, a total of 118 major caregivers of enterostomy patients were investigated using a general information questionnaire, a self-efficacy scale, and a perceived social support scale.Results:The score of sense of coherence in major caregivers of enterostomy patients was 58.40±9.17, and the average scores of all dimensions, from high to low, were “controllable sense，” “understandable sense，”and “meaningful sense.” Sense of coherence was positively correlated with self-efficacy and perceived social support ( r=0.457, P<0.01; r=0.369, P<0.01). Hierarchical multiple regression analysis showed that self-efficacy and perceived social support had a positive predictive effect on sense of coherence and explained 35.2% of the variance ( R′ 2=0.352, F=25.639, P<0.001). Conclusions:The main caregivers of enterostomy patients had a low level of sense of coherence. Self-efficacy and perceived social support have a positive effect on sense of coherence. Medical staff should take targeted measures to help caregivers improve their self-efficacy and social support system in order to improve their sense of coherence.

【Objective】 To explore the clinical features of dermatomyositis and diagnostic value of MRI. 【Methods】 The clinical and imaging data of 61 patients with dermatomyositis were analyzed retrospectively. 【Results】 Among the 61 patients， there were 15 males and 46 females with the average age of 45.3 years. The course of disease was 10 days to 12 years. All of them had different degrees of skin lesions， including 57 cases of myasthenia and or myalgia， 4 cases of dysphagia， 2 cases of dyspnea， and 2 cases of drinking water and coughing. There were 18 cases complicated with interstitial lung disease， 1 case complicated with Sjogren’s syndrome， 1 case complicated with arthritis， 1 case complicated with rhabdomyolysis， and 1 case complicated with kidney damage and liver insufficiency. MRI examination performed in 46 patients with dermatomyositis detected 43 cases of abnormal manifestations， 41 cases of muscle inflammatory edema， 37 cases of subcutaneous adipose tissue edema， and 40 cases of myofascitis. 【Conclusion】 The clinical manifestations of dermatomyositis are complex and have certain imaging features. Combined with the laboratory examinations of muscle enzymes and autoantibodies， electromyography， skin and muscle biopsy， they can provide clinical diagnostic evidence. MRI is an important means to diagnose and evaluate the extent and progression of dermatomyositis.

Objective:To explore rumination status and its influencing factors among enterostomy patients, so as to provide references for the formulation of interventions.Methods:Using convenience sampling method, 120 patients with enterostomy who were treated and followed up in the Fifth Affiliated Hospital of Sun Yat-Sen University from July to December 2019 were selected as the research subjects. General information questionnaire, Event Related Rumination Inventory Scale, Simplified Scale of Resilience and Perceived Social Support Scale were applied in the investigation.Results:The invasive rumination score of enterostomy patients was (13.64±4.88) and the purposive rumination score was (14.90±3.72) . Multiple linear regression analysis showed that age, self-care degree of stoma, resilience and perceived social support explained 38.1% of the variance of invasive rumination ( P<0.01) . Education, occupation, resilience and perceived social support explained 41.9% of the variation of invasive rumination ( P<0.01) . Conclusions:The rumination of enterostomy patients was in the lower middle level. It is suggested that clinical staff pay more attention to the patients with low age, poor self-care ability of colostomy, low education level and unemployed state. At the same time, measures should be taken to improve the level of patients' resilience and improve their social support system, so as to promote the patients' positive psychological adjustment.

Objective:To explore the effect of thinking field therapy based on narrative nursing in patients with first-diagnosed acute leukemia.Methods:From March 2018 to March 2020, convenience sampling was used to select 200 first-diagnosed acute leukemia patients in the Second Hospital of Hebei Medical University as the research object. According to the random number table method, patients were divided into the control group with 100 cases and the research group with 100 cases. The control group performed narrative nursing on the basis of conventional nursing, and the research group conducted the thinking field therapy based on the nursing intervention of the control group. We evaluated the scores of Self-rating Anxiety Scale (SAS) , Self-rating Depression Scale (SDS) , The MOS 36-Item Short Form Health Survey (SF-36) and the revised Piper Fatigue Scale (PFS-R) .Results:After the intervention, the SAS and SDS scores of the two groups of patients decreased, and scores of the research group were lower than those of the control group. SF-36 scores increased and PFS-R scores decreased in both groups, and the SF-36 score of the research group was higher than that of the control group, and the PFS-R score of the research group was lower than that of the control group. The above differences were statistically significant ( P<0.05) . Conclusions:On the basis of narrative nursing, giving leukemia patients the thought field therapy can effectively improve the patients' quality of life, reduce the patients' anxiety and depression levels, and ameliorate the patients' psychological status.

Tetanus consists of neonatal tetanus and non-neonatal tetanus. Non-neonatal tetanus remains a serious public health problem, although neonatal tetanus has been eliminated in China since 2012. Non-neonatal tetanus is a potential fatal disease. In the absence of medical intervention, the mortality rate of severe cases is almost 100%. Even with vigorous treatment, the mortality rate remains 30%-50% globally. These specifications aim to regulate non-neonatal tetanus diagnosis and treatment in China, in order to improve medical quality and safety. These specifications introduce the etiology, epidemiology, pathogenesis, clinical manifestations and laboratory tests, diagnosis, differential diagnosis, grading and treatment of non-neonatal tetanus.
