Nosocomial infections (NIs) are a critical issue affecting the quality of healthcare. In this study, we performed a retrospective study to explore the incidence rates, mortality rates, and microbial spectrum of NIs in Beijing Chest Hospital, a tuberculosis (TB) specialized hospital in China. Our data demonstrate that the overall incidence rate of inpatients with NIs slightly decreased from 2012 to 2016, which may be associated with the implementation of hand hygiene measures, while the mortality rates associated with NI did not significantly change. In addition, the species distribution of NIs was quite different from that presented in previous reports, and Klebsiella pneumoniae was the most frequently isolated microorganism.

BACKGROUND: MicroRNA is a kind of single-stranded non-coding RNA whose length is about 22 nucleotides and its abnormal expression is related to disease closely. This study is aiming to explore the relative expression of miR-34b-3p and miR-302a-5p in the plasma of non-small cell lung cancer (NSCLC) patients and its clinical value. METHODS: The levels of miR-34b-3p and miR-302a-5p in plasma were detected by real-time polymerase chain reaction (RT-PCR) in 86 patients with NSCLC, 64 patients with pulmonary tuberculosis (PTB) and 39 healthy subjects. Analyze their value in diagnosing NSCLC by contrasting and combining carcino-embryonic antigen (CEA), neuron-specific enolase (NSE), and cytokeratin 19 fragments 21-1 (CYFRA21-1). RESULTS: The levels of plasma miR-34b-3p and miR-302a-5p in NSCLC group were significantly higher than those in the PTB group and the healthy group (P<0.05). In patients with NSCLC, the levels of plasma miR-34b-3p was correlated with the diameter of tumor (P<0.01). When using one plasma marker to diagnose NSCLC, miR-302a-5p had the highest sensitivity (82.6%) and CEA had the highest specificity (81.6%). While combined two plasma markers, miR-34b-3p+miR-302a-5p had the highest sensitivity (80.2%) and miR-34b-3p+CEA had the highest specificity (81.4%). As detected multiple markers, miR-302a-5p+NSE+CYFRA21-1 had the highest sensitivity (81.4%) and miR-34b-3p+CEA+NSE had the highest specificity (90.3%). The combination of miR-34b-3p, miR-302a-5p and CEA obtained the highest area under the curve (AUC), which was 0.832. Logistic regression model indicated that miR-34b-3p was independent risk factor for NSCLC compared to control groups. CONCLUSIONS Plasma miR-34b-3p and miR-302a-5p could be used as biological markers for the diagnosis of NSCLC.

We assessed the incidence of adverse drug reactions (ADRs) with anti-TB medications and evaluated the risk factors for developing ADRs in previously treated tuberculosis patients in China. All patients received the first-line anti-TB regimen (2HREZS/6HRE) as recommended by the national guidelines. Clinical and laboratory evaluations were performed once a month. Out of the 354 participants, 262 (74.0%) experienced ADRs such as hyperuricemia (65.0%, 230/354), hepatotoxicity (6.2%, 22/354) and hearing disturbances (4.8%, 17/354). ADRs were significantly associated with diabetes mellitus [OR (95% CI): 15.5 (2.07-115.87)]; however, weight more than 50 kg [OR (95% CI): 0.41 (0.22-0.85)] was a protective factor for occurrence of ADRs. Hyperuricemia is the most common adverse event but, most patients with hyperuricemia showed increased tolerance for high uric acid levels. Low body weight and diabetes mellitus increased the risk of the occurrence of ADRs during anti-TB treatment.

BACKGROUND: New treatment methods such as targeted therapy and immune checkpoint inhibitors have been applied to lung cancer patients. It is necessary to further understand the patients with lung cancer combined with pulmonary tuberculosis with the development of lung cancer research. The purpose of this study was to analyze the clinical characteristics of lung cancer patients with pulmonary tuberculosis, the status of driver genes, and their relationships. METHODS: A retrospective analysis was performed on 405 patients with lung cancer and pulmonary tuberculosis hospitalized in our hospital from January 2014 to December 2019. The relationship between clinical characteristics and driver genes status was analyzed. RESULTS: Among the 405 patients with lung cancer combined with pulmonary tuberculosis, 77.3% were male and 85.3% were patients with a history of smoking. The pathological type was mainly lung adenocarcinoma. When there were cavities in chest computed tomography (CT) , squamous cell carcinoma was the main type. 214 patients underwent driver genes testing. The epidermal growth factor receptor (EGFR) gene mutation rate was 35.9%, of which 41.8% were exon 19 deletion mutations and 50.9% were exon 21 L858R mutations. When there were cavities in the chest CT, the EGFR mutation rate was significantly reduced (16.1%). The positive rate of anaplastic lymphoma kinase (ALK) fusion gene detection was 2.5%, the mutation rate of c-ros oncogene 1 receptor kinase (ROS1) gene was 1.9%, the mutation rate of V-raf murine sarcoma viral oncogene homolog B1 (BRAF) gene was 1.1%, and the mutation rate of Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS) gene was 10.1%. The genetic mutation rate of female patients with lung cancer and pulmonary tuberculosis was 50.0%, and that of men was 27.9%. CONCLUSIONS Patients with lung cancer and pulmonary tuberculosis are predominantly male with smoking history. Adenocarcinoma is the most common pathological type. The positive rate of gene mutation was not significantly different from that of simple lung cancer, but when there were cavities in the chest image, the genetic mutation rate was significantly reduced.

BACKGROUNDPersonalized medicine becomes essential in lung cancer treatment, however lung-cancer-related gene expression profiles in Chinese patients remain unknown. In this study, the correlation of gene expression profiles and clinical characteristics in non-small-cell lung cancer (NSCLC) was investigated.

METHODSSeventy-six Chinese patients with NSCLC were enrolled in the study to investigate mRNA expression profiles of excision repair cross complement group 1 (ERCC1), thymidylate synthetase (TYMS), ribonucleotide reductase (RRM1), class III β-tubulin (TUBB3), and epidermal growth factor receptor (EGFR) genes and their correlation with patient clinical characteristics. A novel liquidchip technology was used to detect mRNA expression levels in formalin fixed paraffin embedded tumor pathology samples. The relationships between gene expression and clinical characteristics were assessed using the Mann-Whitney test.

RESULTSERCC1 mRNA levels were higher in tumors from patients with metastatic disease than patients with non-metastatic disease (P = 0.021), and higher in adenocarcinomas than squamous cell carcinomas (P = 0.006). Increased TUBB3 mRNA expression levels were found in patients with performance status (PS) 1 in comparison with PS 0 (P = 0.049), with poorly differentiated tumors in comparison with tumors that were moderately and well differentiated (P ≤ 0.000 1), and with advanced stage in comparison with early stage disease (P ≤ 0.000 1).

CONCLUSIONSERCC1 mRNA levels were higher in metastatic adenocarcinoma NSCLC; TUBB3 mRNA levels were significantly higher in poorly differentiated tumors and in advanced stage NSCLC, which indicates the poor prognosis.

The early diagnosis of lung cancer can improve the survival rate of patients. Using imaging method to screen high-risk population plays an important role in early detection and early diagnosis. More and more research shows that liquid biopsy can replace and supplement the method. Detection of circulating tumor cells (CTCs), circulating tumor DNA (ctDNA), microRNA (miRNA), exosomes, and tumor educated platelets (TEPs) in patients' peripheral blood can be used for the early diagnosis of lung cancer, and may provide appropriate medical advice for high-risk population with negative imaging finding. The full text reviews the detection methods of these markers, their value in the early diagnosis, as well as their advantages and limitations, in order to promote the application of liquid biopsy in the early diagnosis and other fields.

Objective: To investigate the status of nurses' humble leaders and nurses in seeking feedback, and to analyze the relationship between them. Methods: From August to September 2018, 436 nurses from Beijing Luo he Hospital affiliated to Capital Medical University were selected as the research subjects. The questionnaires were surveyed using general data questionnaire, humble leadership scale and feedback seeking scale. Results: The head nurse′s humble leadership scale was divided into (3.22±0.38) points, and the nurses' feedback seeking behavior was divided into (3.51±0.56) points. The head nurse′s humble leadership was positively correlated with the nurses' feedback seeking behavior (r=0.679, P<0.05). Conclusions The head nurse′s humble leadership can positively promote the nurse′s feedback seeking behavior. The head nurse should pay attention to the leadership qualities of the humble leader, so as to effectively improve the level of feedback seeking behavior.

Objective: To investigate the correlation between serum asymmetric dimethylarginine (ADMA) and cystatin C (CysC) in degenerative calcific aortic valvular disease and its clinical application value. Methods: One hundred and eighty patients with degenerative calcific aortic valvular disease who were treated in Beijing Luhe Hospital Affiliated to Capital Medical University from June 2016 to June 2018 were selected as the study subjects, and another 82 healthy subjects from the same hospital in the same period were selected as the control group. Serum ADMA and CysC levels were detected by enzyme-linked immunosorbent assay and latex-enhanced immunoturbidimetric assay. Risk factors of degenerative calcific aortic valvular disease were analyzed by Logistic regression analysis. Evaluation of the diagnostic efficacy of serum ADMA and CysC for degenerative calcific aortic valvular disease was used by receiver operating characteristic curve. Results: There were no significant differences in the general data between the two groups in terms of age, gender, body mass index, drinking history, smoking history, and history of hypertension (P>0.05). The systolic blood pressure(SBP), diastolic blood pressure (DBP), heart rate (HR), total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterin(LDL-C), CysC and ADMA levels of the study group were significantly higher than those of the control group [(131.51 ± 19.09) mmHg (1 mmHg=0.133 kPa) vs. (126.48 ± 16.68) mmHg, (91.11 ± 16.35) mmHg vs. (86.89 ± 10.71) mmHg, (74.39 ± 15.22) beats/min vs. (70.09 ± 13.01) beats/min, (4.51 ± 1.12) mmol/L vs. (4.15 ± 0.92) mmol/L, (1.91 ± 0.63) mmol/L vs. (1.60 ± 0.65) mmol/L, (2.59 ± 1.13) mmol/L vs. (2.27 ± 0.85) mmol/L, (1.01 ± 0.22) mg/L vs. (0.79 ± 0.16) mg/L, (20.17 ± 6.38) ng/L vs. (11.88 ± 4.22) ng/L], and left ventricular ejection fraction (LVEF), high density lipoprotein cholesterin (HDL-C) levels were significantly lower than those of the control group [(56.45 ± 9.21)%vs. (60.87 ± 10.02)%, (1.56 ± 0.63) mmol/L vs. (1.76 ± 0.62) mmol/L], there were significant differences (P<0.05). Logistic multivariate regression analysis showed that serum CysC and ADMA were independent risk factors for degenerative calcific aortic valvular disease (P<0.05). Receiver operator characteristic (ROC) curve analysis showed that area under curve (AUC) of serum CysC for degenerative valvular heart disease was 0.785, with a sensitivity of 71.67%, and a specificity of 73.17%. The AUC of serum ADMA for degenerative valvular heart disease was 0.862, with a sensitivity of 71.67%, and a specificity of 87.80%. The AUC of serum CysC combined with ADMA in the diagnosis of degenerative valvular heart disease was 0.910, with a sensitivity of 85.56%, and a specificity of 84.15%, which was significantly higher than the two alone (Z=4.897 and 3.335, P<0.05). Conclusions Serum ADMA is positively correlated with CysC in patients with degenerative valvular heart disease, and can be used as diagnostic serum markers for degenerative calcific aortic valvular disease. It has clinical reference value for improving the diagnosis of degenerative calcific aortic valvular disease.

Tuberculosis (TB), a chronic communicable disease, continues to be a global public health concern. Slow decline of TB incidence and prevalence, human immunodeficiency virus/TB coinfection, growth of multidrug-resistant/extensively-resistant TB have made the control of TB even more challenging. Chemotherapy of TB has developed for decades and now also faces similar challenges.
