Study on the Application Effect of Humanoid Figure Teaching Method in the Improvement of Job Competence and Humanistic Care Ability of Newly Recruited Nurses / 中国医学伦理学

To explore the effects of the humanoid figure teaching method on the improvement of humanistic care and job competence of newly recruited nurses. A total of 72 newly recruited nurses in our hospital were selected as the research objects. The research objects were divided into control group and observation group, with 36 in each group. The control group was taught by traditional nursing methods, and the observation group was taught by the humanoid figure teaching method. The clinical teaching effect, core competence and humanistic care ability were compared between the two groups of newly recruited nurses. The results showed that the newly recruited nurses in the observation group had higher academic performance, nursing ward round scores, teaching satisfaction and patient family satisfaction than the control group (P<0.05). The newly recruited nurses in the observation group were better than the newly recruited nurses in the control group in terms of core competence and humanistic care ability (P<0.05). Therefore, the humanoid figure teaching method can effectively improve the clinical teaching effect of nursing work, enhance the clinical competence and humanistic care ability of newly recruited nurses, which is conducive to the development of clinical teaching and work. The humanoid figure teaching method guides newly recruited nurses from the perspective of "whole person", infiltrate the medical humanistic spirit into clinical nursing work, and provide patients with personalized services with in-depth and humanistic care.

Molecular characteristics of diffuse large B-cell lymphoma with high expression of MYC:analysis of 45 cases / 临床与实验病理学杂志

Purpose To explore the molecular features of diffuse large B-cell lymphoma(DLBCL)with high expression of MYC.Methods The clinical data of 45 cases of DLBCL were collected.Immunohistochemical EnVision method was used to classify the patients into the group with high expression of MYC and the group with low expression of MYC.All samples were subjected to DNA targeted sequencing and molecular typing was performed using the LymphGen online tool.Cellular origin was determined by using the Lymph2Cx method.The correlation be-tween MYC overexpression and clinicopathological parameters was analyzed by the x2 test and Fisher precise test.Survival curves were drawn and survival-related factors were analyzed u-sing Cox univariate and multivariate regression.ResultsCases were classified into DLBCL with high expression of MYC(n=17)and DLBCL with low expression of MYC(n=28).Com-pared to the group with low expression of MYC,the group with high expression of MYC had more PIM1,MYD88,CD79B,CD58 and PRDM1 mutations(76.5％vs 28.6％,70.6％vs 32.1％,58.8％vs28.6％,29.4％vs3.6％,29.4％vs 3.6％,P＜0.05),MCD were more frequently found(58.8％vs 10.7％,P=0.001),GCB were rarely found(17.6％vs 50.0％,P=0.030).Overall survival was significantly shorter in DLBCL with high expression of MYC(P＜0.05).Cox multi-factorial analysis showed that age was an independent prognostic factor for DLBCL(P＜0.05).Conclusion Patients with high expression of MYC were frequently characterized as MCD and ABC,and PIM1,MYD88,CD79B,CD58 and PRDM1 muta-tions were common.Patients with high expression of MYC had a poorer prognosis.

Role of non-coding RNA and exosomes in pathogenesis of gestational diabetes mellitus and their early diagnostic value / 中国组织工程研究

BACKGROUND:In recent years,there have been many studies on the mechanism of exosomal non-coding RNA in gestational diabetes mellitus,but there is a lack of the latest systematic review of exosomes from different sources,especially placental sources. OBJECTIVE:To summarize the changes and potential roles of microRNA(miRNA),long non-coding RNA(lncRNA),circular RNA(circRNA),and exosomes in gestational diabetes mellitus to provide potential targets for early screening and treatment of clinical gestational diabetes mellitus. METHODS:A literature search was conducted on PubMed,Web of Science,China National Knowledge Infrastructure,WanFang Data,and VIP databases to retrieve relevant articles on non-coding RNA or exosomal non-coding RNA in relation to gestational diabetes mellitus.A total of 74 articles were included for review. RESULTS AND CONCLUSION:(1)Non-coding RNAs play important pathological and physiological roles in the lifecycle activities,and increasing evidences suggest that non-coding RNAs are involved in the occurrence and development of gestational diabetes mellitus by regulating various physiological functions.This provides a new direction for the research of gestational diabetes mellitus.(2)Exosomes are widely present in the human body.Various cells can secrete exosomes,such as red blood cells,epithelial cells,and placental cells.Non-coding RNAs found in exosomes from different sources have been demonstrated to play a role in the pathogenesis,diagnosis,and treatment of gestational diabetes mellitus.(3)MiRNA and gestational diabetes mellitus:The role of peripheral blood miRNA in gestational diabetes mellitus is mainly to affect the functions of trophoblast cells,pancreatic beta cells and blood glucose levels in gestational diabetes mellitus;placental miRNA can reflect the severity of gestational diabetes and impair the function of trophoblast cells.(4)LncRNA and gestational diabetes mellitus:Peripheral blood lncRNA can induce insulin resistance through the phosphatidylinositol 3-kinase/protein kinase B pathway and may provide new insights for the diagnosis and treatment of gestational diabetes mellitus;placental lncRNA can regulate proliferation and migration of placental trophoblast cells,promoting the occurrence and development of gestational diabetes mellitus.(5)CircRNA and gestational diabetes mellitus:Peripheral blood and placental circRNA can induce the occurrence and development of gestational diabetes mellitus by impairing the proliferation,migration and metabolism of placental trophoblast cells.(6)Non-coding RNA in exosomes and gestational diabetes mellitus:Peripheral blood non-coding RNA in exosomes can affect gestational diabetes mellitus blood glucose levels and glucose homeostasis,and participate in the occurrence and development of gestational diabetes mellitus by influencing placental function.(7)Non-coding RNA has the potential to serve as biomarkers for early diagnosis of gestational diabetes mellitus.Additionally,engineered exosomes can better achieve targeted therapy for gestational diabetes mellitus.These latest findings provide a reference for both basic research and clinical translation of gestational diabetes mellitus.(8)In the future,improvements in the extraction and purification methods of peripheral blood exosomes should be improved,and factors such as race,diet and physical activity should be excluded to improve the reproducibility of results.Further prospective clinical studies are required to explore the clinical application of circulating non-coding RNA and exosomes in the prediction and diagnosis of gestational diabetes mellitus.

Analysis of prognostic factors of extranodal NK/T-cell lymphoma treated with pegaspargase/L-asparaginase: a multicenter retrospective study / 中华血液学杂志

Objective: To explore the prognostic factors of extracellular NK/T cell lymphoma (ENKTL) treated with pegaspargase/L-asparaginase. Methods: The clinical data of 656 ENKTL patients diagnosed at 11 medical centers in the Huaihai Lymphoma Working Group from March 2014 to April 2021 were retrospectively analyzed. The patients were randomly divided into two groups: a training set (460 cases) and a validation set (196 cases) at 7∶3, and the prognostic factors of the patients were analyzed. A prognostic scoring system was established, and the predictive performance of different models was compared. Results: Patients' median age was 46 (34, 57) years, with 456 males (69.5% ) and 561 nasal involvement (85.5% ). 203 patients (30.9% ) received a chemotherapy regimen based on L-asparaginase combined with anthracyclines, and the 5-year overall survival rate of patients treated with P-GEMOX regimen (pegaspargase+gemcitabine+oxaliplatin) was better than those treated with SMILE regimen (methotrexate+dexamethasone+cyclophosphamide+L-asparaginase+etoposide) (85.9% vs 63.8% ; P=0.004). The results of multivariate analysis showed that gender, CA stage, the Eastern Cooperative Oncology Group performance status (ECOG PS) score, HGB, and EB virus DNA were independent influencing factors for the prognosis of ENKTL patients (P<0.05). In this study, the predictive performance of the prognostic factors is superior to the international prognostic index, Korean prognostic index, and prognostic index of natural killer lymphoma. Conclusion: Gender, CA stage, ECOG PS score, HGB, and EB virus DNA are prognostic factors for ENKTL patients treated with pegaspargase/L-asparaginase.

Analysis of the real situation of medication in the population with gout achieving T2T indicators: a multicentre real-world study / 中华风湿病学杂志

Objective:To explore the therapeutic characteristics of population with gout achieving treat-to-target (T2T) indicators through real-world research and evaluate their safety.Methods:A total of 3 287 patients diagnosed with gout by rheumatologists in 21 first-class tertiary hospitals in 10 provinces, municipalities, and autonomous regions in China from January 2015 to December 2021 were included in this polycentric cross-sectional study. The database included patients′ general information, disease characteristics, and clinical application of traditional Chinese and Western medicine treatment measures. SPSS and Excel software were used for data analysis. Frequency analysis, cluster analysis, and factor analysis were used to summarize the characteristics and rules of treatment measures for patients with gout who achieved the target after treatment. The occurrence of adverse events (AE) was recorded during treatment.Results:After treatment, 691 visits (7%) achieved the serum urate (SUA) target, and the most frequent use of urate-lowering therapy (ULT) was febuxostat, followed by benzbromarone. The most common treatment options were following: GroupⅠ: traditional Chinese medicine (TCM) decoction-TCM external treatment-physical exercise-proprietary Chinese medicine; GroupⅡ: ferulic acid-nonsteroidal anti-inflammatory drugs (NSAIDs); Group Ⅲ: allopurinol-sodium bicarbonate-benzbromarone; Group Ⅳ: glucocorticoid-colchicine; Group Ⅴ: febuxostat. A total of 5 898 visits (60%) chieved manifestations of joint pain VAS scores target, and the most frequently used drug to control joint symptoms was NSAIDs. The frequency of use of drugs to control joint symptoms were 2 118 times (usage rate reached 35.9%), while the frequency of ULT were 2 504 times (usage rate reached 42.5%), which was higher than the joint symptom control drug. The most common treatment options were following: Group Ⅰ: proprietary Chinese medicine-TCM decoction-TCM external treatment-physical exercise; Group Ⅱ: NSAIDs-colchicine hormones; Group Ⅲ: allopurinol, Group Ⅳ: benzbromarone; Group Ⅴ: febuxostat. A total of 59 adverse events occurred during treatment.Conclusion:The proportions of gout patients who reach target serum urate level & good control of joint symptoms are both very low, and ULT and anti-inflammatory prescription patterns are very different from international guidelines, so it is necessary to strengthen the standardized management of gout patients. At the same time, life intervention measures account for a certain proportion of the treatment plans for the T2T population, and further exploration is needed.

Efficacy of crisaborole ointment in clinical symptom relief in the early stage of childhood atopic dermatitis and in symptom improvement in the remission stage: a multicenter clinical study / 中华皮肤科杂志

Objective:To evaluate the efficacy and tolerability of crisaborole 2% ointment in the treatment of childhood atopic dermatitis (AD) at the early stage, and to compare the efficacy of every-other-day (Qod) regimen versus twice-a-week (Biw) regimen against recurrence in the remission stage of AD.Methods:A multicenter, randomized, open-label clinical trial was conducted. Totally, 150 children with mild to moderate AD aged 2 - < 18 years were enrolled from 6 hospitals (including Beijing Children′s Hospital, Capital Medical University, etc), and randomly divided into the Qod group (76 cases) and the Biw group (74 cases). In the acute stage of AD, both groups were treated with topical crisaborole 2% ointment on skin lesions twice a day for 2 - 4 weeks, as well as with emollients throughout the whole body. The improvement of early clinical symptoms was evaluated, and the occurrence of adverse reactions was recorded in the follow up. Once the investigator′s static global assessment (ISGA) scores decreased to 1 point or less, the patient would be enrolled into the remission stage. In the remission stage of AD, patients in the Qod group and Biw group were treated with crisaborole ointment every other day and twice a week respectively; the recurrence rate of AD in the remission stage was evaluated, as well as the severity of skin lesions, itching, life quality, and the occurrence of adverse reactions at weeks 4, 8, and 12. Statistical analysis was carried out with SPSS 23.0 software by using t test for comparisons of normally distributed continuous data between two groups, Mann-Whitney U test for non-normally distributed data, chi-square test for enumeration data, and Kaplan-Meier method for analysis of survival rates. Results:A total of 142 patients were enrolled in the modified intention-to-treat population, including 71 in the Qod group and 71 in the Biw group. In the acute stage of AD, the improvement of itching and skin lesions self-reported by the children or their family members occurred on days 1.9 (1.0, 3.0) and 2.0 (1.0, 4.1) after the application of crisaborole ointment, respectively. At the end of treatment in the acute stage, 89 children (62.7%) achieved ISGA 0/1 and successfully transferred into the remission stage. The follow-up in the remission stage was completed in 83 patients (44 in the Qod group and 39 in the Biw group). In addition, recurrence occurred in 19 (43.2%) and 12 (30.8%) patients in the Qod group and Biw group respectively, and there was no significant difference in the recurrence rate between the two groups ( χ2 = 1.36, P = 0.243) ; the average time to recurrence was 64.25 (95% CI: 53.33 - 75.17) days and 75.78 (95% CI: 65.46 - 86.10) days in the Qod group and Biw group respectively. Among the patients who were in the remission stage and had not yet experienced relapse at weeks 4, 8, and 12, there were no significant differences in the eczema area and severity index (EASI) scores, ISGA scores, pruritus numerical rating scale (NRS) scores, or quality-of-life scores between the two groups (all P > 0.05) at any time points, except for the ISGA scores at week 12 (Biw group: 0 [0, 1] point vs. Qod group: 1 [0, 1] point; Z = -2.31, P = 0.021). A total of 146 patients were enrolled in the safety set. During the study period, 70 adverse events occurred in 65 patients, with an incidence rate of 44.5%, and all were mild or moderate adverse events; 55 (37.7%) patients experienced discomfort at the medication site, which mainly referred to pain (45 cases, 30.8%) and mostly occurred in the tender and skinfold areas. Conclusions:Crisaborole 2% ointment could effectively relieve clinical symptoms in children with mild to moderate AD in the early stage, and intermittent treatment could continuously relieve clinical symptoms in the remission stage. The common adverse reaction was discomfort at the application site in the early stage of AD. There was no significant difference in the impact on AD recurrence in the remission stage between the Qod regimen and Biw regimen.

Progress on standardized nutrition therapy for head and neck cancer during the peri-radiotherapeutic period / 中华放射肿瘤学杂志

Malnutrition is a common complication of cancer patients, and solving nutrition problems is still one of the challenging tasks in clinical practice. The incidence of malnutrition in head and neck cancer patients during the peri-radiotherapeutic period is high, which is not only related to disease-mediated metabolic disorders, complications and psychological factors, but also associated with the toxic and side effects induced by radiotherapy. Malnutrition will reduce the tolerance, accuracy, and therapeutic effects of radiotherapy, which in turn lowers the quality of life and even adversely affects the prognosis of disease. Medical nutrition therapy can improve the nutritional status of the body, ensure smooth progress of radiotherapy, and improve the efficacy of comprehensive cancer treatment. It is necessary and urgent to deliver standardized nutrition therapy and management of head and neck cancer patients during the peri-radiotherapeutic period. Nutritional risk screening, nutritional assessment, and acute radiation injury assessment are required to develop an individualized nutrition treatment plan and make dynamic adjustment. In this article, relevant literature of nutrition therapy for head and neck radiotherapy at home and abroad was summarized, and the standardized nutrition therapy for head and neck cancer patients during the peri-radiotherapeutic period was reviewed.

OBJECTIVE@#To investigate the effects of decitabine (DEC) combined with all-trans retinoic acid (ATRA) on the number of immune cells, efficacy and adverse reactions in the treatment of myeloid neoplasms patients.@*METHODS@#Eighty-four patients with myeloid tumors, including AML, MDS-EB-1 or MDS-EB-2 treated by the regimen containing decitabine in our hospital from January 2009 to October 2019 were enrolled and retrospectively analyzed, among the patients, 21 patients treated with DEC alone, 24 patients treated with DEC combined with ATRA (DEC/ATRA) and 39 patients treated with DEC combined with G-CSF priming regimen (DEC/priming). The changes of peripheral blood immune cell levels before and after treatment of the patients between the three groups were compared, and the differences in clinical efficacy and adverse reactions of the patients between the three groups were also compared.@*RESULTS@#There was no statistical differences in the number of immune cells among the patients in the three groups before treatment (P>0.05). NK cell levels decreased significantly in the patients in DEC and DEC/ATRA group after treatment (P<0.05); After treatment, the levels of CD8+ and CD3+T cells in the patients treated by DEC /priming regimen significantly increased (P<0.05), while the levels of CD3-HLA-DR+ B cells significantly decreased (P<0.05). The overall response rate (ORR) of the patients in DEC/ATRA group (75%) and DEC/priming group (74.36%) was significantly higher than 42.86% in DEC monotherapy group, and the differences showed statistically significant (P<0.05), while the ORR between the patients in DEC/ATRA and DEC/priming group showed no statistic differences (P>0.05). There were no statistical differences in overall survival (OS) and incidence of bleeding between the patients in the three groups (P>0.05). The incidences of grade 3 to 4 bone marrow suppression and the infection rate of the patients in DEC monotherapy and DEC/ATRA group were significantly lower than that in DEC/priming regimen group after treatment (all P<0.05), however, there was no statistical difference between DEC monotherapy and the DEC/ATRA group.@*CONCLUSION@#The efficacy of DEC/ATRA on myeloid neoplasms is comparable to that of DEC/priming regimen, and the anti-myeloid tumor effect of DEC/ATRA regimen may be related to the regulation of NK cells and T cells.

Association of Next Generation Sequencing Based Genotypic Profiling with MICM Characteristics in NPM1 Mutated Acute Myeloid Leukemia / 中国实验血液学杂志

OBJECTIVE@#To explain the clinicobiological heterogeneity of NPM1 mutated (NPM1mut) acute myeloid leukemia (AML) by analyzing the association between next-generation sequencing (NGS) profiles and MICM characteristics in patients with this AML subtype.@*METHODS@#Data of 238 NPM1mut patients with available NGS information on 112 genes related to blood disease was collected, and χ2 test and nonparametric test were used to analyze the distribution association between NGS-detecting mutations and conventional MICM parameters.@*RESULTS@#In entire NPM1mut cohort, totaling 240 NPM1 mutation events were identified, of whom 10 (10/240, 4.2%) were missense mutations, which did not involve any W288 or W290 locus and were found exclusively in NPM1mut/FLT3-ITD- group. All but one of these missense mutations (9/10, 90%) were accompanied by AML subtype-defining recurrent cytogenetic or molecular abnormalities, of which 7 cases were in the low risk and 2 in the high risk. NPM1mut occurred solely as an insertion/deletion (indel) type in the NPM1mut/FLT3-ITD+ group. The incidence of favorable plus unfavorable karyotypes in NPM1mut/FLT3-ITD- group was higher than in NPM1mut/FLT3-ITD+ group (6.4% vs. 0, P=0.031). The positive rates of CD34 and CD7 in NPM1mut/FLT3-ITD+ group were significantly higher than in NPM1mut/FLT3-ITD- group (CD34: 47.9% vs. 20.6%, P<0.001; CD7: 61.5% vs. 29.9%, P<0.001).

Combining biofeedback based on virtual reality technology with transcranial magnetic stimulation aids the recovery of dysphagic stroke survivors / 中华物理医学与康复杂志

Objective:To observe the effect of combining biofeedback therapy (BFT) based on virtual reality technology with repeated transcranial magnetic stimulation (rTMS) on dysphagia among stroke survivors.Methods:Eighty patients were randomly divided into a control group, an rTMS group, a BFT group and a combined treatment group, each of 20. In addition to routine dysphagia rehabilitation, the rTMS and BFT groups were given those treatments, while the combined treatment group was given both for 4 weeks. Swallowing function was evaluated before and after the treatment using the standardized swallowing assessment (SSA) and the functional oral intake scale (FOIS). Videofluoroscopy was used to quantify the subjects′ oral and pharyngeal phases and their aspiration status.Results:Significant improvement was observed in the average FOIS and SSA scores, as well as in the average oral and pharyngeal phases and in aspiration. The combined treatment group′s results were significantly better in all those aspects than those of the other 3 groups.Conclusion:The combined application of biofeedback therapy based on virtual reality technology and repeated transcranial magnetic stimulation can improve the swallowing function of stroke survivors with dysphagia. It is worthy of clinical promotion.

Application of chromosomal microarray analysis in prenatal diagnosis of pregnant women with advanced age / 中华医学遗传学杂志

OBJECTIVE@#To assess the value of chromosomal microarray analysis (CMA) for the detection of fetal anomalies among pregnant women with advanced age.@*METHODS@#CMA results of 562 cases, in addition with the outcome of pregnancy and neonatal follow-up were reviewed.@*RESULTS@#Among the 562 amniotic fluid samples, 73 cases (12.99%) of fetal chromosomal abnormalities were detected, which included 21 cases (3.73%) of chromosomal aneuploidies and 52 cases (9.25%) of copy number variations (CNVs). The latters included 27 cases of pathological CNVs (4.80%), 4 cases of possible pathogenic CNVs (0.71%) and 42 cases of variants with unknown clinical significance (7.47%). Compared with those under 35, the detection rate of fetal chromosomal aneuploidies for women with advanced age was higher under the indications of voluntary test, abnormal ultrasonic structures, abnormal ultrasonic soft index and risks indicated by non-invasive prenatal testing (NIPT). No significant difference was found in the detection rate of CNVs between those ≥35 and 0.05). 552 cases (98.22%) of pregnant women have completed the followed up. Among 31 women with pathological and possible pathogenic fetal CNVs detected by CMA, 25 had terminated the pregnancy, 6 (19.35%) have delivered without obvious abnormality. 41 pregnant women with fetal CNVs of unknown clinical significance have completed the follow up, among whom 3 had terminated the pregnancy, 1 newborn was found with malformation after birth, which yielded an abnormal pregnancy rate of 9.76%. 480 pregnant women with negative CMA results have completed the follow up, among whom 5 (1.04%) had abnormal pregnancy or delivered a child with birth defect.@*CONCLUSION@#There is a certain difference between the outcome of pregnancy predicted by CMA testing and the actual outcome. The pregnancies with fetal CNVs with unknown clinical significance detected by CMA have a high adverse rate, which should attract clinical attention. CMA testing should be recommended for pregnant women with advanced age regardless of whether they have other symptoms. CMA combined with other detection methods is the trend for prenatal diagnosis.

Targeting "undruggable" c-Myc protein by synthetic lethality / 医学前沿

Synthetic lethal screening, which exploits the combination of mutations that result in cell death, is a promising method for identifying novel drug targets. This method provides a new avenue for targeting "undruggable" proteins, such as c-Myc. Here, we revisit current methods used to target c-Myc and discuss the important functional nodes related to c-Myc in non-oncogene addicted network, whose inhibition may cause a catastrophe for tumor cell destiny but not for normal cells. We further discuss strategies to identify these functional nodes in the context of synthetic lethality. We review the progress and shortcomings of this research field and look forward to opportunities offered by synthetic lethal screening to treat tumors potently.
