Myocardial ischemia-reperfusion injury （MIRI） is a serious complication of revascularization in patients with myocardial infarction. The nuclear factor erythroid 2-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） signaling pathway plays an important role in the pathological process of MIRI. Currently，research has found that traditional Chinese medicine has a good effect on myocardial injury caused by ischemia-reperfusion. Based on the Nrf2/HO-1 signaling pathway，this article summarizes the action mechanism of traditional Chinese medicine formulas and monomers in intervening with MIRI. It is found that traditional Chinese medicine formulas （Yixin formula，Wenyang tongmai formula，Dingxin formula Ⅰ），monomers such as terpenoids （ginkgolides， astragaloside Ⅳ，ginsenosides），phenols （brazilin，hematoxylin A，resveratrol） and quinones （aloe，emodin） can alleviate MIRI by activating the Nrf2/HO-1 signaling pathway，inhibiting oxidative stress and inflammatory reactions，etc.

The paper reports a case of coenzyme Q10 deficiency nephrotic syndrome associated with coenzyme Q2 gene mutation and reviews the literature on this topic. The patient presented with hematuria, proteinuria, and a diminution of vision as clinical manifestations. But the proteinuria was not relieved after sufficient doses of glucocorticoids for over 2 months. The patient′s birth history was unremarkable, and his parents were both healthy and not consanguineous. Whole exome sequencing revealed that the patient had a mutation of coenzyme Q2 gene at c.973A>G(p.T325A) and c.517C>T(p.R173C). Combined with renal biopsy pathology, the patient was diagnosed with hereditary nephropathy and started the supplements of coenzyme Q10 after stopping glucocorticoid treatments immediately. After 5 weeks of therapy, the patient′s 24-h urine protein quantification decreased from 6.01 g to 1.53 g.

Objective:To investigate the urinary sediment findings and the clinicopathologic features of IgA nephropathy (IgAN) patients with acute kidney injury (AKI).Methods:It was a retrospective study. The patients with renal biopsy-proven primary IgAN in Peking University First Hospital from January 31, 2013 to July 31, 2015 were selected. According to whether AKI occurred at renal biopsy or not, the patients were divided into AKI group and non-AKI group. Morning urine samples were obtained on the day of renal biopsy. Urine sediments, including various cells and casts, were examined. The clinical data, urinary sediments, and renal pathological changes were compared between the two groups. Logistic regression analysis was performed to identify the association between clinical pathological changes, urinary sediment indicators and AKI, or clinical pathological changes and urinary sediment indicators.Results:There were 502 IgAN patients enrolled in this study, with age of (36.1±12.1) years old and 261 males (52.0%). The incidence of AKI was 11.4% (57/502) among the enrolled patients at the time of renal biopsy. Common causes of AKI included gross hematuria-induced AKI (10 cases), acute tubulointerstitial nephritis (10 cases), crescentic IgAN (9 cases), malignant hypertensive renal damage (6 cases), and multiple etioloqy or unknown etiology (22 cases). Compared with non-AKI group, AKI group had higher proportions of males and malignant hypertension, higher levels of proteinuria and urinary erythrocyte counts, and higher frequencies of gross hematuria, leukocyturia, renal tubular epithelial cells, and granular casts (all P<0.05). AKI group also had higher proportions of severe tubular atrophy/interstitial fibrosis (T2) and cellular/cellular fibrous crescent formation (C2) than non-AKI group (both P<0.05). Logistic regression analysis results showed that, there were statistically significant differences in the correlation between AKI and gender, 24 h urinary protein, urinary erythrocyte counts, granular casts and renal tubular atrophy/interstitial fibrosis (T) scores (all P<0.05). Hematuria, leukocyturia, red blood cell casts, white blood cell casts, granular casts, and fatty casts were correlated with endothelial hypercellularity (E) and cellular/cellular fibrous crescent formation (C) scores, respectively (all P<0.05). Hematuria was correlated with mesangial hypercellularity (M) scores ( OR=2.613, 95% CI 1.520-4.493, P=0.001). Hematuria ( OR=1.723, 95% CI 1.017-2.919, P=0.043) and fatty casts ( OR=2.646, 95% CI 1.122-6.238, P=0.026) were correlated with segmental sclerosis or adhesion (S) scores. Leukocyturia ( OR=1.645, 95% CI 1.154-2.347, P=0.006) and fatty casts ( OR=2.344, 95% CI 1.202-4.572, P=0.012) were correlated with T scores. Epithelial cell cast was correlated with C scores ( OR=1.857, 95% CI 1.174-2.939, P=0.008). Conclusions:AKI is a common complication among IgAN patients with diverse etiology and more severe clinicopathological features. Urinary sediment findings can reflect renal pathological changes to some extent, and therefore assist in the clinical diagnosis and treatment of IgAN patients with AKI.

Objective:To understand the status quo of emotional intelligence, emotional labor, and humanistic caring ability of medical staff, and to clarify their internal relationship.Methods:Convenience sampling was used to select 713 medical staff from a grade A tertiary hospital in Chengdu, Sichuan Province, China. Emotional Intelligence Scale, Humanistic Caring Scale, and Emotional Labor Scale were used to measure the emotional intelligence, humanistic caring ability, and emotional labor of medical staff. SPSS 22.0 software was used to establish a database for statistical description and analysis. Process 3.2 software was used to analyze the mediating effect.Results:In humanistic caring ability, the average score of comprehension dimension was the highest (75.62±8.20) and the average score of patience dimension was the lowest (58.53±5.01). In emotional labor, the average score of the deep action dimension was the highest (23.39±3.85) and the average score of the surface action dimension was the lowest (17.73±3.18). In emotional intelligence, the average score of self-emotion evaluation dimension was the highest (21.76±3.30) and the average score of other-emotion evaluation dimension was the lowest (20.07±3.71). Positive correlations were found between humanistic caring ability and emotional intelligence, between humanistic caring ability and emotional labor, and between emotional intelligence and emotional labor ( P<0.01). Humanistic caring ability had a partial mediating effect between emotional intelligence and emotional labor. Humanistic caring ability had direct and indirect effects on emotional labor, and the effect sizes were 0.279 and 0.029, respectively. Conclusion:Emotional intelligence has a direct positive predictive effect on emotional labor, humanistic caring ability as an intermediary variable indirectly and positively predicts emotional labor. Humanistic caring ability plays a partial mediating role between emotional intelligence and emotional labor. Attention should be paid to the emotional labor of medical staff, and the emotional labor of medical staff should be improved through targeted training on emotional intelligence and humanistic caring ability. These efforts will improve the current situation and establish a harmonious doctor-patient relationship.

ERK pathway regulated the programmed death ligand-1 (PD-L1) expression which was linked to the response of programmed death-1 (PD-1)/PD-L1 blockade therapy. So it is deducible that ERK inhibitor could enhance the efficacy of PD-1 inhibitor in cancer immunotherapy. In this study, PD0325901, an oral potent ERK inhibitor, strongly enhanced the efficacy of PD-1 antibody

Background: Symptoms of irritable bowel syndrome with diarrhea (IBS-D) are known to be influenced by circadian oscillation; however, the pathophysiological mechanism is still unclear. Aims: To investigate the role and underlying mechanism of colon circadian clock gene Bmal1 involved in the occurrence of symptoms in IBS-D patients. Methods: Forty-six patients with IBS-D and 34 normal controls from Army Medical Center of PLA during September 2018 to February 2021 were recruited in this study. IBS-severity scoring system (IBS-SSS) was used to evaluate the severity of IBS-D symptoms. A colonoscopy was performed to obtain biopsy specimens from rectosigmoid colon. The concentration of 5-hydroxytryptamine (5-HT), and expressions of Bmal1 and chromogranin A (CgA), a biomarker of enterochromaffin cells (EC cells), in colonic mucosa were detected by ELISA and double-labeled immunofluorescence, respectively. Results: Both the 5-HT concentration and number of EC cells in colonic mucosa of IBS-D patients were significantly higher than those of the normal controls (all P< 0.05). Bmal1 was mainly expressed in intestinal epithelial cells and was highly expressed in EC cells. Co-expression of Bmal1 and CgA was observed. Compared with the normal control group biopsied at the same time point, expression of Bmal1 was significantly higher in specimens taken at 9 a.m., and expression of Bmal1 was significantly lower in specimens taken at 17 p.m. in IBS-D patients (all P< 0.05). Spearman correlation coefficient analysis showed that Bmal1 expression at 9 a.m. was positively correlated with the total score of IBS-SSS and subscore of abdominal pain and discomfort (r

Objective:To explore effects of family medical information management platform on medication discrepancy, medication compliance and nutritional management of patients with colorectal cancer undergoing chemotherapy.Methods:Using the convenient sampling method, a total of 64 patients with colorectal cancer who received chemotherapy in Henan Provincial People's Hospital from March 2018 to June 2019 were selected as the research objects. According to the random number table method, they were divided into the control group and the observation group, with 32 cases in each group. The control group adopted conventional management, while the observation group adopted family medical information management platform. After intervention, Medication Discrepancy Tool (MDT) and the Chinese Version of Morisky Medication Compliance Scale were used to compare the incidence of medication discrepancy and medication compliance of patients of the two groups. The nutritional status of patients in the two groups was compared using BMI, hemoglobin, total protein, albumin and modified Subjective Global Assessment (SGA) scores.Results:After the intervention, the incidence of medication discrepancy in the observation group was 21.88% (7/32) , lower than 62.50% (20/32) in the control group, and the difference was statistically significant (χ 2=10.827, P<0.01) . After the intervention, there was a statistically significant difference in medication compliance between the two groups ( Z=2.207, P<0.05) . After intervention, BMI, hemoglobin, total protein and albumin of the observation group were higher than those of the control group, and the modified SGA score was lower than that of the control group, and the differences were statistically significant ( t=-2.340, -3.007, -2.137, -3.334, 3.107; P<0.05) . After intervention, the number of normal nutritional cases in the observation group was higher than that in the control group, and the number of severe malnutrition cases was lower than that in the control group, and the differences were statistically significant (χ 2=4.267, 5.379; P<0.05) . Conclusions:The application of family medical information management platform can reduce medication discrepancy of patients with colorectal cancer undergoing chemotherapy, improve their medication compliance and reduce the occurrence of malnutrition.

In this retrospective cohort study, we aim to evaluate the effect of endocapillary hypercellularity (E) lesions on the renal prognosis and response to immunosuppressive therapy, especially diffuse endocapillary hypercellularity lesion in IgA nephropathy (IgAN). A total of 365 patients with IgAN and E lesions and 31 patients with diffuse E lesions and over 12-month follow-up period were included in this study. We performed an 1∶1 propensity score to identify controls with matched clinical and pathological features from 769 IgAN patients without E lesions. The end-point was defined as a 30% decrease in estimated glomerular filtration rate (eGFR) or end-stage kidney disease. The kidney survival of the two groups was compared by Kaplan-Meier analysis. During median follow-up period of 41 months, kidney survival rates in patients with E lesions were 96.0% at 1 year, 83.6% at 3 years, 67.7% at 5 years; while they were 96.9% at 1 year, 83.6% at 3 years, and 68.7% at 5 years in patients without E lesions ( P=0.265).The HRof immunosuppressive therapy was 1.038 (95% CI 0.749-1.440) and 1.113 (95% CI 0.770-1.609) in patients not receiving immunosuppressive therapy ( P=0.781). (2) During median follow-up period of 52.5 months, the kidney survival rates in patients with diffuse E-lesion were 100.0% at 1 year, 96.2% at 3 years, 74.5% at 5 years; while they were 96.2% at 1 year, 82.3% at 3 years, and 63.7% at 5 years in patients without E-lesion ( P=0.158). The HR of immunosuppressive therapy was 0.625 (95% CI 0.213-1.839) and 0.447 (95% CI 0.028-7.191) in patients not receiving immunosuppressive therapy ( P=0.825). E lesion or diffuse E lesion may not be associated with prognosis or response to immunosuppressive therapy.

Objective: To study the relationship between the father presence and the mental health diathesis of the middle school students,and to provide a reference for targetedly instructing fathers’ participation into family education. Methods: The participants were selected by using random whole class sampling method and Father Presence Questionnaires (FPQ-R-B), and then 577 junior middle school students were recruited, including high and low level of father presence(HF & LF). Chinese Adolescent Mental Health Diathesis was used to investigate the effect of father presence on eight subscales of mental health diathesis. Results: Single factor ANOVA showed that in the subscales of coping style (2.84±0.52,2.80±0.60), self (2.87±0.56,2.79±0.59), attribution style (2.85±0.56,2.78±0.55) and adaptation (2.92±0.56,2.85±0.59), HF group scored significantly higher than LF group(F=4.32,5.27,7.13,8.62,P<0.05). Simple effect analysis reveals that for girls there was no significant difference between the HF and LF groups (2.87±0.45,2.86±0.48, P>0.05), but for boys the score of the HF group was significantly higher than that of the LF group(2.93±0.34,2.85±0.40)(F=5.93,P<0.05). Conclusion High level of father presence is related to better performance in coping style, self, attribution style, adaptation, and personality quality, and its impact on personality qualitty shows gender differences.

Objective: To investigate the current status and real performance of the detection of RUNX1-RUNX1T1 fusion transcript levels and WT1 transcript levels in China through interlaboratory comparison. Methods: Peking University People’s Hospital (PKUPH) prepared the samples for comparison. That is, the fresh RUNX1-RUNX1T1 positive (+) bone morrow nucleated cells were serially diluted with RUNX1-RUNX1T1 negative (-) nucleated cells from different patients. Totally 23 sets with 14 different samples per set were prepared. TRIzol reagent was added in each tube and thoroughly mixed with cells for homogenization. Each laboratory simultaneously tested RUNX1-RUNX1T1 and WT1 transcript levels of one set of samples by real-time quantitative PCR method. All transcript levels were reported as the percentage of RUNX1-RUNX1T1 or WT1 transcript copies/ABL copies. Spearman correlation coefficient between the reported transcript levels of each participated laboratory and those of PKUPH was calculated. Results: ①RUNX1-RUNX1T1 comparison: 9 samples were (+) and 5 were (-) , the false negative and positive rates of the 20 participated laboratories were 0 (0/180) and 5% (5/100) , respectively. The reported transcript levels of all 9 positive samples were different among laboratories. The median reported transcript levels of 9 positive samples were from 0.060% to 176.7%, which covered 3.5-log. The ratios of each sample’s highest to the lowest reported transcript levels were from 5.5 to 12.3 (one result which obviously deviated from other laboratories’ results was not included) , 85% (17/20) of the laboratories had correlation coefficient ≥0.98. ②WT1 comparison: The median reported transcript levels of all 14 samples were from 0.17% to 67.6%, which covered 2.6-log. The ratios of each sample’s highest to the lowest reported transcript levels were from 5.3-13.7, 62% (13/21) of the laboratories had correlation coefficient ≥0.98. ③ The relative relationship of the reported RUNX1-RUNX1T1 transcript levels between the participants and PKUPH was not always consistent with that of WT1 transcript levels. Both RUNX1-RUNX1T1 and WT1 transcript levels from 2 and 7 laboratories were individually lower than and higher than those of PKUPH, whereas for the rest 11 laboratories, one transcript level was higher than and the other was lower than that of PKUPH. Conclusion The reported RUNX1-RUNX1T1 and WT1 transcript levels were different among laboratories for the same sample. Most of the participated laboratories reported highly consistent result with that of PKUPH. The relationship between laboratories of the different transcript levels may not be the same.
