ITGAM-mediated macrophages contribute to basement membrane damage in diabetic nephropathy and atherosclerosis.

BACKGROUND: Diabetic nephropathy (DN) and atherosclerosis (AS) are prevalent and severe complications associated with diabetes, exhibiting lesions in the basement membrane, an essential component found within the glomerulus, tubules, and arteries. These lesions contribute significantly to the progression of both diseases, however, the precise underlying mechanisms, as well as any potential shared pathogenic processes between them, remain elusive. METHODS: Our study analyzed transcriptomic profiles from DN and AS patients, sourced from the Gene Expression Omnibus database. A combination of integrated bioinformatics approaches and machine learning models were deployed to identify crucial genes connected to basement membrane lesions in both conditions. The role of integrin subunit alpha M (ITGAM) was further explored using immune infiltration analysis and genetic correlation studies. Single-cell sequencing analysis was employed to delineate the expression of ITGAM across different cell types within DN and AS tissues. RESULTS: Our analyses identified ITGAM as a key gene involved in basement membrane alterations and revealed its primary expression within macrophages in both DN and AS. ITGAM was significantly correlated with tissue immune infiltration within these diseases. Furthermore, the expression of genes encoding core components of the basement membrane was influenced by the expression level of ITGAM. CONCLUSION: Our findings suggest that macrophages may contribute to basement membrane lesions in DN and AS through the action of ITGAM. Moreover, therapeutic strategies that target ITGAM may offer potential avenues to mitigate basement membrane lesions in these two diabetes-related complications.

Family Aggregation of Hematological Malignancies Discovered from an Acute Myeloid Leukemia Patient with STK11 and THBD Gene Mutation.

Acute myeloid leukemia (AML) is a large class of heterogeneous hematological malignancies with the highest incidence rate in acute leukemia. Its pathogenesis is still unclear, which may be related to genetics. According to the latest AML NCCN guidelines, genes involved in AML family genetic changes include RUNX1, ANKRD26, CEBPA. Finding new genes related to AML genetics is of great significance for predicting the prognosis of patients, developing targeted drugs, and selecting transplant donors. Here, we report a case of adult female AML patient whose three relatives suffered from hematological malignancies, including Waldenstrom macroglobulinemia, NK/T-cell lymphoma, and angioimmunoblastic T-cell lymphoma. The screen for genetic susceptibility genes related to blood and immune system diseases was carried out, and the result showed that the patient herself, her son, her daughter, and her two cousins all had STK11 p.F354L and/or THBD p.D486Y mutations. At present, there is no research or case report on the relationship between STK11/THBD and family aggregation of hematological malignancies. We report for the first time that an AML patient with STK11 and THBD mutations has a family aggregation of hematological malignancies, and consider that STK11 and THBD may be related to family genetic changes which ultimately cause the family aggregation of hematological malignancies.

A Retrospective Study of Perioperative Nursing Care of Patients After Percutaneous Left Atrial Appendage Occlusion.

PURPOSE: To describe the retrospective audit examining nursing care of nonvalvular atrial fibrillation treated by percutaneous left atrial appendage closure (PLAAC). DESIGN: PLAAC is a new technique for patients with atrial fibrillation unsuited for long-term oral anticoagulation treatment. The nursing care for patients treated by PLAAC has not yet been standardized. METHODS: We performed a retrospective analysis of 259 patients with nonvalvular atrial fibrillation who underwent PLAAC in our department between August 2014 and June 2018. The data included preoperative evaluations, discussions, and preparations, including psychological care and atrial thrombosis screening; postoperative observations, including electrocardiograph monitoring; prevention and care of complications; administration of postoperative anticoagulation therapy; and postoperative education, including detailed discharge guidance and regular follow-up. FINDINGS: All patients were discharged after 5-10 days of hospitalization. In the perioperative period, 4 cases (1.5%) developed serious complications, including 3 cases (1.2%) of delayed cardiac tamponade, cured by pericardial drainage, and 1 case of a suspected air embolism, which spontaneously recovered. During a mean follow-up period of 25.9 ± 7.9 months, all patients had good adherence to medical instructions and there were no cases of occluder displacement or shedding, thromboembolism, or severe bleeding complications. CONCLUSIONS: The best therapeutic effect of PLAAC is strongly associated with the preoperative and postoperative training of nursing staff and the development of standard nursing procedures, including the establishment of observation and nursing manuals for complications. This study provides nursing practice information to aid in the standardization of nursing procedures for this new type of interventional therapy.

[Effect of rFLC and dFLC on Clinical Prognosis of Patients with Newly Diagnosed Multiple Myelome and Best Cutoff Value].

OBJECTIVE: To investigate the influence of rFLC and dFLC on clinical prognosis and best cutoff value in patients with newly diagnosed multiple myelome(MM). METHODS: Clinical data of 240 patients with newly diagnosed MM treated in Western Theater General Hospital of People's Liberation Army from January 2010 to June 2016 were collected and retroanalyzed. All patients were divided into different groups according to the interquartile spacing levels of rFLC and dFLC, the median OS and PFS of patients in different groups were compared. The influencing factors of prognosis in newly diagnosed MM patients were analyzed by univariate and multivariate methods, the influence of different cutoff values of rFLC and dFLC on clinical prognosis were evaluated. RESULTS: The median progression-free survival time of female patients with M-protein IgA type and I stage for ISS stage were significantly longer than those of male, other M-protein types and other ISS stage（P<0.05）. The median OS of patients without hypercalcemia was significantly higher than that of patients with hypercalcemia（P<0.05）. The median progression-free survival(PFS) time of patients with dFLC <110.95 mg/L was significantly longer than that of patients with dFLC=110.95-2 781.44 mg/L and >2 781.44 mg/L（P<0.05）. The median overall survival time of patients with dFLC ＜110.95 mg/L and ＞2 781.44 mg/L was significantly longer than that of patients with dFLC=110.95-2 781.44 mg/L（P<0.05）. The median overall survival time of patients with rFLC <14.71 mg/L was significantly longer than that of patients with rFLC >14.71-367.96 mg/L and >367.96 mg/L（P<0.05）. Univariate analysis of Cox regression model indicated that dFLC at all levels showed higher influence on the OS and PFS of patients as compared with rFLC（P<0.05）. Multivariate analysis of Cox regression model showed that rFLC and dFLC expression level were the independent prognostic factors of patients（P<0.05）. The most significant influence value on clinical prognosis of patients were observed when rFLC level ≤14.71 or dFLC level ≤110.95 mg/L（P<0.05）. The median OS of patients with rFLC level ≤14.71 was significantly higher than that of other groups（P<0.05）. There was significant difference in median PFS between patients with rFLC ≤14.71 and ≥367.96 mg/L（P<0.05）. The median OS and PFS of patients with dFLC ≤110.95 mg/L were significantly longer than those in other two groups（P<0.05）. CONCLUSION: The levels of rFLC and dFLC closely relate to clinical prognosis of patients with new diagnosed MM; the risk of recurrence or death is lowest in patients with rFLC level ≤14.71 mg/L or dFLC level ≤110.95 mg/L, which can be used as the ideal cutoff value for prognosis evaluation.

[Influencing Factors on Prognosis of Adult Patients with Chronic Primary ITP Treated with Rituximab and Predictive Value of Platelet Count].

OBJECTIVE: To investigate the influencing factors on prognosis of adult patients with chronic primary immune thrombocytopeuia (ITP) after rituximab treatment and predictive value of platelet (Plt) count. METHODS: Clinical data of 52 adult patients with chronic primary ITP treated with rituximab from January 2012 to December 2016 were retrospectively analyzed, including 32 patients for failed in treatment as group A and 20 patients for succeeded in treatment as group B. The independent risk factors influencing the clinical efficacy of rituximab were analyzed. The influence of CD41+ megakaryocyte count in bone marrow diagnosed for first time on the response rate of patients with 1-year followed-up were observed, and the Plt count were calculated to predict the clinical efficacy index and the best cut-off point. RESULTS: The CD41+ megakaryocyte count in bone marrow for first time treatment in group B were significantly higher than that in group A (P＜0.05). Multivariate Logistic regression analysis showed that the number of CD41+ megakaryocytes in bone marrow＜150 at first diagnosis was the independent risk factor influencing the clinical efficacy of rituximab (OR=5.40，95%CI：1.82-15.66，P=0.00). The response rate of 1-year followed-up in patients with CD41+ megakaryocyte count ≥150 at first diagnosis was significantly higher than that of CD41+ megakaryocyte count ＜150 (P＜0.05). The Plt count level in group B was significantly lower than that in group A at the 3rd, 14th, 21th, 30th, 60th, 90th, 180th, 270th and 360th days after first treatment with rituximab (P＜0.05). ROC curve analysis showed that the best cut-off point for Plt count was 50×109/L and AUC was 0.68 at the 14th day after first treatment with rituximab (95%CI: 0.57-0.78, P=0.00). The predictive sensitivity and specificity of clinical efficacy in adult patients with chronic primary ITP treated with rituximab were separately 48.73% and 87.58%, and the AUC in 30th and 60th day after rituximab treatment were separately 0.74 (95%CI: 0.64-0.87, P=0.00), 0.93 (95%CI：0.82-0.98，P=0.00). CONCLUSION: Adult patients with chronic primary ITP may possess long-term remission after rituximab treatment, but the prognosis is poor for patients with bone marrow megakaryocyte count ＜150. The Plt counts in 14th, 30th and 60th days after rituximab treatment can effectively predict the long-term clinical efficacy and guide the formulation of treatment plans.

Experiences of front-line nurses combating coronavirus disease-2019 in China: A qualitative analysis.

OBJECTIVE: To explore the experiences of front-line nurses combating the coronavirus disease-2019 epidemic. DESIGN AND SAMPLE: Fifteen front-line nurses caring for COVID-19 patients were recruited from two hospitals in Wuhan, China from January 26 to February 5, 2020. Data were collected through semi-structured individual interviews and analyzed using standard qualitative methods. RESULTS: Four theme categories emerged from the data analysis: (a) "Facing tremendous new challenges and danger"; (b) "Strong pressure because of fear of infection, exhaustion by heavy workloads and stress of nursing seriously ill COVID-19 patients"; (c) "Strong sense of duty and identity as a healthcare provider"; (d) "Rational understanding of the epidemic-the nurses believed that the epidemic would soon be overcome and would like to receive disaster rescue training." CONCLUSIONS: Although the intensive rescue work drained front-line nurses, both physically and emotionally, they showed a spirit of dedication and felt a responsibility to overcome this epidemic. Their experiences provide useful insights into implementing a safer public health emergency rescue system in preparation for future outbreaks of infectious diseases. Specifically, psychological support and humanistic care should be provided to front-line nurses to maintain their well-being, and nationwide emergency rescue training and disaster education should be implemented.

Incidence and Related Factors for Hospital-Acquired Pneumonia Among Older Bedridden Patients in China: A Hospital-Based Multicenter Registry Data Based Study.

Objective: To identify the incidence and related factors for hospital-acquired pneumonia (HAP) among older bedridden patients in China. Study design and setting: This multicenter registry data-based study conducted between November 2015 and March 2016 surveyed 7,324 older bedridden patients from 25 hospitals in China (six tertiary, 12 non-tertiary, and seven community hospitals). The occurrence of HAP among all participants was monitored by trained investigators. Demographics, hospitalization information and comorbidity differences were compared between patients with and without HAP. A multilevel regression analysis was used to explore the factors associated with HAP. Results: Among 7,324 older bedridden patients, 566 patients were diagnosed with HAP. The incidence of HAP in this study was 13.9 per 1,000 person-days. There were statistical differences in gender, age, length of bedridden days, BMI, smoking, department, undergoing general anesthesia surgery, ventilator application, Charlson comorbity index (CCI) score, disturbance of consciousness, tranquilizer use, glucocorticosteroid use, and antibiotic use between patients with HAP and patients without HAP (all p < 0.05). Multilevel regression analysis found no significant variance for HAP at the hospital level (0.332, t = 1.875, p > 0.05). There were significant differences for the occurrence of HAP among different departments (0.553, t = 4.320, p < 0.01). The incidence density of HAP was highest in the ICU (30.1‰) among the selected departments, followed by the departments of neurosurgery (18.7‰) and neurology medicine (16.6‰). Individual patient-level factors, including older age, disturbance of consciousness, total CCI score, ICU admission, and glucocorticoid and antibiotic use, were found to be associated with the occurrence of HAP (all p < 0.05). Conclusion: A relatively high incidence density of HAP among older bedridden patients was identified, as well as several factors associated with HAP among the population. This suggests that attention should be paid to the effective management of these related factors of older bedridden patients to reduce the occurrence of HAP.

Reduced Serum Levels of Brain-Derived Neurotrophic Factor Are Related to Mild Cognitive Impairment in Chinese Patients with Type 2 Diabetes Mellitus.

BACKGROUND: Brain-derived neurotrophic factor (BDNF) is involved in obesity, type 2 diabetes mellitus (T2DM), and cognitive dysfunction. The present study sought to assess the role of serum levels of BDNF in the pathophysiological process of mild cognitive impairment (MCI), a preclinical phase of dementia in 715 Chinese patients with T2DM. METHODS: Cross-sectional data were obtained from 715 patients with T2DM recruited from a Chinese diabetes center. Serum levels of BDNF were measured with sandwich enzyme-linked immunosorbent assay. The influence of BDNF on MCI was examined using univariate and multivariate binary logistic regression analyses. RESULTS: In univariate and multivariate logistic regression analyses, for each one-unit increase of BDNF, the unadjusted and adjusted risk of MCI decreased by 9% (OR 0.91; 95% CI 0.88-0.93, p < 0.001) and 6% (0.94; 0.87-0.98, p < 0.001) respectively. In multivariate models comparing the first (Q1), second and third quartiles against the fourth quartile of BDNF, BDNF in Q1 and Q2 were associated with MCI, and increased risk of MCI by 275% (OR 3.75; 95% CI 2.38-6.03) and 155% (2.55; 1.32-4.02). These results suggested that for each 1 ng/mL increase of serum level of BDNF, the association became stronger among obese diabetic patients (OR 0.91, 95% CI 0.85-0.96; p < 0.001) versus nonobese diabetic patients (OR 0.95, 95% CI 0.86-0.98; p = 0.001). CONCLUSION: The present data demonstrated that reduced serum levels of BDNF were associated with increased risk of MCI and might be useful for identifying diabetic patients at risk of dementia for early prevention strategies.

Outpatient Experience of Human Caring Scale (OEHC-Scale): Improvement by Delphi Method.

Based on the outpatient interview and literature review, the initial framework of the outpatient experience of human caring scale was formed with 9 dimensions of outpatient process. The research aim was to improve the scale by Delphi method. Sixteen experts in medical management, human caring or medical education were invited to evaluate the importance of the dimensions and items of the scale and provided some expertise via filling out the Delphi consultation questionnaires twice in the consulting round. In the first round, the recovery rate showing the experts' positivity was 80%; the coefficient of reliability (Cr) ascertaining the authority of the evaluation was 0.92; the mean and full mark ratios responding the concentration of the evaluation were 2.88-4.94 and 6.25%-93.75% respectively; the coefficients of variation (CV) and the Kendall's W determining the concordance of the evaluation were 5.06%-52.15% and 0.21-0.24 respectively. In the second round, the recovery rate was 93.75%; the Cr was 0.93; the mean was 3.93-4.93; the full mark ratios were 26.67%-93.33%; the Kendall's W was 0.14-0.31, the CV was 5.25%-23.61%. Via the two-round Delphi study, the scale that included 10 dimensions and 61 items has been improved. Ten dimensions are pre-hospital medical service, guidance, registration, waiting, diagnosis & treatment, paying, inspection & assay, medicine receiving, therapy/injection/transfusion and global evaluation. It was concluded that Chinese scholars have paid high attention to human caring and outpatient experience. The experts have given high agreements about the dimensions which were established with Chinese outpatient process. The dimensions are different from the similar researches about outpatient experience study. In the future, it is necessary to survey the outpatients to test the construct validity, internal consistency reliability and others of the scale to improve the scale.

Postharvest Ultrasound-Assisted Freeze-Thaw Pretreatment Improves the Drying Efficiency, Physicochemical Properties, and Macamide Biosynthesis of Maca (Lepidium meyenii).

A novel technique of ultrasound-assisted freeze-thaw pretreatment (UFP) was developed to improve the drying efficiency of maca and bioactive amide synthesis in maca. The optimal UFP conditions are ultrasonic processing 90 min at 30 °C with 6 freeze-thaw cycles. Samples with freeze-thaw pretreatment (FP), ultrasound pretreatment (UP), and UFP were prepared for further comparative study. A no pretreatment (NP) sample was included as a control. The results showed that UFP improved the drying efficiency of maca slices, showing the highest effective moisture diffusivity (1.75 × 10-9 m2 /s). This result was further supported by low-field nuclear magnetic resonance (LF-NMR) analysis and scanning electron microscopy (SEM). The rehydration capacity and protein content of maca slices were improved by UFP. More importantly, contents of bioactive macamides and their biosynthetic precursors were increased in 2.5- and 10-fold, respectively. In conclusion, UFP is an efficient technique to improve drying efficiency, physicochemical properties, and bioactive macamides of maca, which can be applied in the industrial manufacture of maca products.

Identification of maca (Lepidium meyenii Walp.) and its adulterants by a DNA-barcoding approach based on the ITS sequence.

Maca (Lepidium meyenii) is an herbaceous plant that grows in high plateaus and has been used as both food and folk medicine for centuries because of its benefits to human health. In the present study, ITS (internal transcribed spacer) sequences of forty-three maca samples, collected from different regions or vendors, were amplified and analyzed. The ITS sequences of nineteen potential adulterants of maca were also collected and analyzed. The results indicated that the ITS sequence of maca was consistent in all samples and unique when compared with its adulterants. Therefore, this DNA-barcoding approach based on the ITS sequence can be used for the molecular identification of maca and its adulterants.

Risk factors and precautions of inpatient suicide from the perspective of nurses: A qualitative study.

The risk factors and precautions of inpatient suicide were explored. Thirty suicide victims were drawn from the adverse event reports of suicidal act during hospitalization in a general hospital from 2008 to 2014. Data were gathered from the focus group interviews of twelve nurses who had experienced inpatient suicide. The data were analyzed by using analytical technique based on grounded theory, and software QSR NVIVO8 was used to aid the collation of data. Three main themes of risk factors about inpatient suicide emerged from the analysis: individual value, social factors and environmental factors. The individual value was categorized into different groups such as sense of guilt, hopelessness and low self-esteem. Social factors included two aspects of negative life events and social support. Three themes of precautions about inpatient suicide appeared in this study: evaluation, nursing and information exchange. Evaluation was elaborated from both physical and psychological assessments. This finding extends existing work of risk factors and precautions about inpatient suicide and brings new knowledge about the reasons why inpatients commit suicide.

Efficient production of succinic acid from macroalgae hydrolysate by metabolically engineered Escherichia coli.

In this study, microbial production of succinic acid from macroalgae (i.e., Laminaria japonica) was investigated for the first time. The engineered Escherichia coli BS002 exhibited higher molar yield of succinic acid on mannitol (1.39±0.01mol/mol) than glucose (1.01±0.05mol/mol). After pretreatment and enzymatic hydrolysis, L. japonica hydrolysate was mainly glucose (10.31±0.32g/L) and mannitol (10.12±0.17g/L), which was used as the substrate for succinic acid fermentation with the recombinant BS002. A final 17.44±0.54g/L succinic acid was obtained from the hydrolysate after 72h dual-phase fermentation. The yield was as high as 1.24±0.08mol/mol total sugar, which reached 73% of the maximum theoretical yield. The results demonstrate that macroalgae biomass represents a novelty and economical alternative feedstock for biochemicals production.

Enhanced antitumor effect of combining chemotherapy with Epstein-Barr virus (EBV)-specific cytotoxic T lymphocytes in mice with EBV-related non-Hodgkin's lymphoma.

Epstein-Barr virus (EBV)-related non-Hodgkin's lymphoma (NHL) represents a major problem in hematological clinical studies due to its drug tolerance and refractoriness. EBV infection is a key factor driving the process of tumor growth. Immune therapy is an important biotherapeutic method of treating cancer, which is attracting increasing attention. We hypothesized that combining conventional chemotherapy with immune therapy in the treatment of EBV-related NHL may achieve better outcomes. First, we successfully cloned large numbers of EBV-specific T cells by immune stimulation ex vivo. Subsequently, the combined therapy was applied in a murine model of human EBV-related NHL. As expected, combined therapy inhibited tumor growth more effectively compared with monotherapy. In addition, we continuously tested the tumor-associated immune microenvironment and observed that the numbers of tumor-infiltrating cytotoxic T lymphocytes (CTLs) and macrophages were elevated following combined therapy. These effects suggest that EBV-specific CTLs may indirectly promote an innate immune reaction in lymphoma by activating tumor-infiltrating macrophage proliferation. Our findings may provide a guide for the prospective treatment of EBV-related NHL.

Performance of a haloalkaliphilic bioreactor and bacterial community shifts under different COD/SO4²â» ratios and hydraulic retention times.

Sulfur dioxide from flue gas was converted into sulfate after the absorption of alkaline solutions. Haloalkaliphilic microorganisms have been used in reducing sulfate to decrease expenses and avoid sulfide inhibition. The effects of different COD/SO4(2-) ratios and hydraulic retention times (HRTs) on the sulfate removal efficiency and bacterial community were investigated in model experiments. Ethanol showed better performance as an electron donor than lactate. The optimum COD/SO4(2-) ratio and HRT were 4.0 and 18 h, respectively, with respective sulfate removal efficiency and rate of 97.8 ± 1.11% and 6.26 ± 0.0710 g/Ld. Sulfide concentrations reached 1,603 ± 3.38 mg/L. Based on denaturing gradient gel electrophoresis analysis of 16S rDNA, the major sulfate-reducing bacterium (SRB) was Desulfonatronovibrio sp., which was only detected at a COD/SO4(2-) ratio of 4.0 using ethanol as an electron donor. Different HRTs had no significant effect on the band corresponding to this species. PCR results show that methane-producing archaea (MPA) were from the acetoclastic methanogenic family Methanosarcinaceae. Quantitative real-time PCR did not demonstrate any significant competition between SRB and MPA. The findings of this study indicate that sulfate reduction, nitrate reduction, and sulfide oxidization may occur in the same bioreactor.

Performance of a haloalkaliphilic bioreactor under different NO3(-)/SO4(2-) ratios.

Effects of NO3(-)/SO4(2-) ratio on denitrification and sulfate removal efficiency were investigated in model experiments applying haloalkaliphilic bioreactor. The reduction of both substrates performed well at different NO3(-)/SO4(2-) ratios ranging from 17.6 to l.5. The removal rates of nitrate and sulfate were 6 and 1.39kgm(-3)d(-1), respectively, at NO3(-)/SO4(2-) ratio 3.0, while sulfide concentration reached up to 703gm(-3). The major sulfate-reducing and denitrifying bacteria were Desulfonatronovibrio sp. and Halomonas campisalis, respectively. Decrease in NO3(-)/SO4(2-) ratio led to obvious changes in bacterial community. Although the sulfate reducers became dominant, the population of denitrifying ones also increased as it was demonstrated by analysis of PCR-amplified 16S rDNA fragments, which suggested that SRB and DB coexisted well in bioreactor.

Improving Breast Cancer Outcomes among Women in China: Practices, Knowledge, and Attitudes Related to Breast Cancer Screening.

Background. Breast cancer is a major public health issue and the most commonly diagnosed cancer for women worldwide. Despite lower incidence rates than those living in Western countries, breast cancer incidence among Chinese women has increased dramatically in the past 20 years. Nevertheless, there is a paucity of studies reporting the attitudes toward and practices of breast cancer screening among Chinese women. Methods. This cross-sectional study examined the practices, knowledge, and attitudes toward breast cancer screening (BCS) on a convenience sample of 400 Chinese women. Results. Among study participants, 75% of the women never had a mammogram and the top three barriers reported were low priority, feeling OK, and lack of awareness/knowledge toward breast cancer screening. The results from the logistic regression model showed increased self-efficacy; having performed monthly self-exams, and having had clinical breast exams in the past two years were significant correlates while demographic variables were not correlated with screening behaviors. Conclusion. The findings provide a foundation to better understand beliefs and practices of Chinese women toward BCS and highlight the critical need for general public, health professionals, and the health care system to work collaboratively toward improving the quality of breast cancer care in this population.
