Biobank is an important platform for translational medicine, precision medicine and drug development. In the past 10 years, although the construction of biobank in China has made great progress, it still faces many challenges. This article analyzes the key issues and also puts forward specific suggestions in the management of biobank from the aspects of ethics issues, quality control of biospecimens, information management, sample and data sharing, so as to provide reference for the construction and development of a high standard biobank.
目的总结炎性肌纤维母细胞瘤的生物学特性，提高对该疾病的综合治疗水平。 方法分析1例来源于结肠术后4个月复发的炎性肌纤维母细胞瘤病例的诊治过程并复习文献。 结果结肠来源的炎性肌纤维母细胞瘤是一种较少见的疾病，单纯手术切除存在复发可能。本例患者结合药物治疗，随访6个月，残余肿瘤大小无明显变化。 结论结肠炎性肌纤维母细胞瘤手术切除后，需结合肿瘤的病理分型及免疫组化结果，选择合适的辅助治疗方式，并定期密切随访。

ObjectiveTo compare the therapeutic effects of invasive-high-flow oxygen therapy (HFNC) and invasive-non-invasive ventilation (NIV) sequential strategies on severe respiratory failure caused by chronic obstructive pulmonary disease (COPD), and explore the feasibility of HFNC after extubation from invasive ventilation for COPD patients with severe respiratory failure.MethodsFrom October 2017 to October 2019, COPD patients with type Ⅱ respiratory failure who received invasive ventilation were randomly assigned to a HFNC group and a NIV group at 1: 1 in intensive care unit (ICU), when pulmonary infection control window appeared after treatments. The patients in the HFNC group received HFNC, while the patients in the NIV group received NIV after extubation. The primary endpoint was treatment failure rate. The secondary endpoints were blood gas analysis and vital signs at 1 hour, 24 hours, and 48 hours after extubation, total respiratory support time after extubation, daily airway care interventions, comfort scores, and incidence of nasal and facial skin lesions, ICU length of stay, total length of stay and 28-day mortality after extubation.ResultsOne hundred and twelve patients were randomly assigned to the HFNC group and the NIV group. After secondary exclusion, 53 patients and 52 patients in the HFNC group and the NIV group were included in the analysis respectively. The treatment failure rate in the HFNC group was 22.6%, which was lower than the 28.8% in the NIV group. The risk difference of the failure rate between the two groups was –6.2% (95%CI –22.47 - 10.43, P=0.509), which was significantly lower than the non-inferior effect of 9%. Analysis of the causes of treatment failure showed that treatment intolerance in the HFNC group was significantly lower than that in the NIV group, with a risk difference of –38.4% (95%CI –62.5 - –3.6, P=0.043). One hour after extubation, the respiratory rate of both groups increased higher than the baseline level before extubation (P<0.05). 24 hours after extubation, the respiratory rate in the HFNC group decreased to the baseline level, but the respiratory rate in the NIV group was still higher than the baseline level, and the respiratory rate in the HFNC group was lower than that in the NIV group [(19.1±3.8) vs. (21.7±4.5) times per minute, P<0.05]. 48 hours after extubation, the respiratory rates in the two groups were not significantly different from their baseline levels. The average daily airway care intervention in the NIV group was 9 (5 - 12) times, which was significantly higher than the 5 (4 - 7) times in the HFNC group (P=0.006). The comfort score of the HFNC group was significantly higher than that of the NIV group (8.6±3.2 vs. 5.7±2.8, P= 0.022), while the incidence of nasal and facial skin lesions in the HFNC group was significantly lower than that in the NIV group (0 vs. 9.6%, P=0.027). There was no significant difference in dyspnea score, length of stay and 28-day mortality between the two groups.ConclusionsThe efficacy of invasive-HFNC sequential treatment on COPD with severe respiratory failure is not inferior to that of invasive-NIV sequential strategy. The two groups have similar treatment failure rates, and HFNC has better comfort and treatment tolerance.
Objective To understand the current situation of nosocomial infection management quality control centers at the municipal and county levels in Guizhou, so as to provide measures for promoting the construction of nosocomial infections management quality control centers at all levels in Guizhou. Methods From September 26th to October 12th 2023, based on the mobile network platform survey questionnaire of the infection prevention and control workshop, a survey was conducted on the establishment, personnel, information technology level, management, and quality control work of the nosocomial infection management quality control centers at the municipal and county levels in Guizhou. Results Nine prefecture-level cities/autonomous prefectures in Guizhou had established municipal-level nosocomial infection management quality control centers. The professional background of the staff at the municipal and county-level quality control centers was mainly nursing (accounting for 36.4% and 58.4%, respectively), and their educational background was mainly undergraduate (accounting for 70.5% and 83.3%, respectively). No quality control center at the municipal or county level had established an information-based quality control platform for nosocomial infection management within the region. Most county-level quality control centers did not have special funds (87.5%), and there were still 16 (25.0%) county-level quality control centers that had not established relevant systems for work and management. The main forms of quality control work carried out by each center were organizing training, on-site inspections, guidance and evaluation, and most of them were conducted irregularly. Conclusions Guizhou has basically formed a quality control system for nosocomial infection management at the provincial, municipal, and county levels. However, the nosocomial infection management quality control network has not fully covered all districts, and policies, funding support, and personnel allocation are still insufficient. Health administrative departments and quality control centers at all levels need to unify monitoring standards and quality control norms, strengthen supervision, improve quality control capabilities, and improve training systems to achieve standardization and normalization of quality control work throughout the province and improve quality control efficiency.
