Factors influencing the interval from isolation to diagnosis of local COVID-19 in Shaanxi Province / 西安交通大学学报(医学版)

【Objective】 To understand the epidemiological characteristics of COVID-19 in Shaanxi Province from December 9, 2021 to January 20, 2022, and analyze the factors influencing the interval from isolation to diagnosis. 【Methods】 We collected the data of local COVID-19 cases from December 9, 2021 to January 20, 2022 published on the official website of Health Commission of Shaanxi Province. Descriptive statistical method was used to analyze the epidemiological characteristics of COVID-19 in Shaanxi Province. Mann-Whitney U test and Kruskal-Wallis H test were used to compare the differences between groups. The unconditional Logistic regression model was applied to analyze the factors influencing the interval between isolation and diagnosis. 【Results】 The outbreak of COVID-19 in Shaanxi Province started on December 9, 2021 and ended on January 20, 2022. The overall change trend of the outbreak showed an "inverted V" shape. A total of 2,080 confirmed local cases were reported, and the main type of disease was mild, with an incidence rate of 5.26/100,000. Xi’an had the most cases, accounting for 98.69% of the total. The reported cases were mainly concentrated in people aged 21 to 55 years old, with a male-to-female sex ratio of 1.19∶1. The median interval from isolation to diagnosis was 3 days, the shortest interval being 0 day and the longest interval being 21 days. Unconditional Logistic regression model analysis showed that the way of finding cases was the factor influencing the interval from isolation to diagnosis. Compared with the way of isolation of the key population, the way of the nucleic acid screening could reduce the risk of late detection of confirmed cases by 89% (OR=0.11, 95% CI: 0.07-0.16). 【Conclusion】 The way of finding cases is the factor influencing the interval from isolation to diagnosis. In the face of the recent intensification of the spread of Omicron variant in mainland China, accurate and rapid identification and detection of confirmed cases can not only reduce the risk of the spread of the epidemic, but also endeavor more time and initiative for the treatment of patients, which is the key to curbing the spread of the epidemic.

@#Introduction: During the early phase of Coronavirus disease (COVID-19), there were various uncertainties, which had a detrimental impact on the prevalence of burnout among critical care personnel worldwide. This study aims to investigate the prevalence of burnout and its associated factors in critical care personnel involved in the COVID-19 pandemic. Methods: This is a single-center, cross-sectional study with 81 critical care personnel for a survey using Copenhagen Burnout Inventory. Binary logistic regression analysis was conducted to identify factors associated with personal burnout. Results: More than half of the respondents were female (60.5%) over the age of 30 (61.7%), and 54.3% were medical doctors. A large number (72.8%) of the respondents experienced personal burnout, with twothirds of them experiencing work-related (65.4%) and client-related burnout (59.3%). Personal burnout was found to be associated with those who had children [OR: 11.31 (1.90, 67.37), p = 0.008], stayed with family, relatives, or friends [OR: 9.40 (1.27, 69.46), p = 0.028], were medical doctors [OR: 26.52 (2.79, 252.22), p = 0.004], worked more than 45 hours per week [OR: 8.68 (1.45, 58.09), p = 0.018], and previously never had COVID-19 viral test [OR: 6.93 (1.17, 40.89), p = 0.033]. Conclusion: Overall, more than half of the critical care personnel experienced burnout. There were possible associations between personal burnout with social characteristics such as having children and living with family, relatives, or friends, and occupational characteristics such as being a medical doctor, long working hours, and previously never had COVID-19 viral test.

Magnolol attenuates right ventricular hypertrophy and fibrosis in hypoxia-induced pulmonary arterial hypertensive rats through inhibition of the JAK2/STAT3 signaling pathway / 中国药理学与毒理学杂志

OBJECTIVE Right ventricular (RV) remodeling is one of the essential pathological features in pulmonary arterial hypertension (PAH). RV hypertrophy or fibrosis are the leading causes of RV remodeling. Magnolol is a com?pound isolated from Magnolia officinalis. It possesses multiple pharmacological activities, such as anti-oxidation and anti-inflammation. This study aims to evaluate the effects and underlying mechanisms of magnolol on RV remodeling in hypoxia-induced PAH. METHODS ① Male SD rats (220 g) were randomly divided into 5 groups (n=10): the normoxia group, the hypoxia group, the hypoxia plus Magnolol (10 and 20 mg·kg-1·d-1) group, and the vehicle group. Rats in the normoxia group were kept in a normoxia environment for 4 weeks, while rats in the hypoxia group were kept in a hypoxic chamber (10％ O2). The rats in the hypoxia plus magnolol groups were administered with magnolol at 10 or 20 mg·kg-1 (ip) once a day for 4 weeks. At the end of 4 weeks, the heart function was assessed by Doppler echocardiography, and then the rats were anesthetized with sodium pentobarbital (30 mg·kg-1, ip). The RVSP was measured by the right heart catheterization method. The heart tissues were collected and dissected to calculate the index of RV remodeling (RV/LV+IVS, RV/tibial length, or RV/body weight). Part of the RV samples was fixed with 4％paraformaldehyde for morphological analysis, while other samples were frozen at-80℃for molecular studies (measurements of ANP, BNP,α-SMA, and col?lagen Ⅰ/Ⅲ mRNA expression as well as p-JAK2/JAK2 and p-STAT3/STAT3 protein levels). ② To evaluate the effect of magnolol on hypoxia-induced myocardial hypertrophy and fibrosis, H9c2 or cardiac fibroblasts were divided into 7 groups: the control group, cells were cultured under normal conditions; the hypoxia group, cells were cultured under hypoxic condition (3％ O2);the hypoxia plus magnolol 10 mg·kg-1 group, magnolol10μmol·L-1 was added to the culture medium before the hypoxia treatment;the hypoxia plus magnolol 30 mg·kg-1 group, magnolol 20μmol·L-1 was added to the culture medium before the hypoxia treatment;the hypoxia plus TG-101348 group, TG-101348 (a specific inhibitor of JAK2) 1μmol·L-1 was added to the culture medium before the hypoxia treatment;the hypoxia plus JSI-124 group, JSI-124 (a specific inhibitor of JAK2) 1μmol·L-1 was added to the culture medium before the hypoxia treatment;and the hypoxia plus vehicle group, an equal volume of vehicle (DMSO) was added to the culture medium before the hypoxia treatment. At the end of the experiments, the cells were collected for morphological and molecular analysis. RESULTS In vivo, male Sprang-Daley rats were exposed to 10％ O2 for 4 weeks to establish an RV remodeling model, which showed hypertrophic and fibrotic features (increases of RV remodeling index, cellular size, hypertrophic and fibrotic marker expression), accompanied by an elevation in phosphorylation levels of JAK2 and STAT3;these changes were attenuated by treating rats with magnolol. In vitro, the cultured H9c2 cells or cardiac fibroblasts were exposed to 3％ O2 for 48 h to induce hypertrophy or fibrosis, which showed hypertrophic (increases in cellular size as well as the expression of ANP and BNP) or fibrotic features (increases in the expression of collagenⅠ, collagenⅢandα-SMA). Administration of mag?nolol and TG-101348 or JSI-124 (JAK2 selective inhibitors) could prevent the process of myocardial hypertrophy and fibrosis, accompanied by the decrease in the phosphorylation level of JAK2 and STAT3. CONCLUSION Magnolol can attenuate RV hypertrophy and fibrosis in hypoxia-induced PAH rats through a mechanism involving inhibition of the JAK2/STAT3 signaling pathway.

Effect and Mechanism of Jiaotaiwan on Cognitive Impairment in Diabetic Mice / 中国实验方剂学杂志

Objective: To explore effect and mechanism of Jiaotaiwan (JTW) on cognitive impairment in diabetic mice. Method: The 40 db/db mice of spontaneous diabetes were randomly divided into model group, JTW 1 group (1.68 g·kg-1), JTW 2 group (3.36 g·kg-1), and JTW 3 group (8.40 g·kg-1), with 8 mice in each group, and 8 C57BL/6J mice were included into normal group. After 8 weeks of treatment, behavioral test,fasting blood glucose (FBG), fasting insulin (Fins), insulin resistance index (HOMA-IR), total triglyceride (TG), total cholesterol (TC), free fatty acids (FFA), high density lipoprotein (HDL), and low density lipoprotein (LDL) were detected. Western blot was used to detect protein expressions of pSer199, pSer202, pSer214, p-Akt, glycogen synthase kinase-3β(GSK-3β), phospho-GSK-3β(p-GSK-3β). Result: Compared with model group, FBG, Fins, HOMA-IR, TG, TC, HDL, FFA in JTW group decreased significantly (P0.01), with a significant improvement in cognitive function (P0.01), protein expressions of taupSer199, pSer202, pSer214 and GSK-3β in hippocampus of mice decreased significantly (PP0.01), and expressions of p-Akt and p-GSK3 beta significantly increased (P0.01). Conclusion: JTW 3 (Coptidis Rhizoma-Cinnamomi Cortex 10:1) can alleviate insulin resistance and cognitive impairment. The mechanism may be related to the inhibition of over-phosphorylation of tau protein, the down-regulation of GSK-3β protein expression and the up-regulation of p-Akt and p-GSK-3β expressions.

Total Ankle Arthroplasty: An Imaging Overview

With advances in implant technology, total ankle arthroplasty (TAA) has become an increasingly popular alternative to arthrodesis for the management of end-stage ankle arthritis. However, reports in the literature do not focus on the imaging features of TAA. Through a literature review, we demonstrate basic design features of the current ankle arthroplasty system, and the normal and abnormal postoperative imaging features associated with such devices. Pre- and postoperative evaluations of ankle arthroplasty mainly include radiography; in addition, computed tomography and magnetic resonance imaging provide further characterization of imaging abnormalities. Familiarization with multimodal imaging features of frequent procedural complications at various postoperative intervals is important in radiological practice.

Objective To observe the efficacy of self-made Arnebiae oil by our hospital on phaseⅠandⅡpressure ulcers. Methods A total of 324 pressure wounds of 283 cases collected from March 2014 to August 2015 were randomly divided into the observation group (145 cases) and the control group (138 cases). The control group received Kangfuxin solution in conjunction with conventional pressure ulcer care treatment, the observation group were treated with Arnebiae oil and conventional pressure ulcer care treatment. The therapeutic effect and healing time of both groups were compared. Results Arnebiae oil was effective in 96.97% (160/165) of the pressure ulcer patients and cured 84.85% (140/165) patients in the observation group. Nearly 84.91%(135/159) patients were effective and 50.94%(81/159) patients were cured in the control group. There was statistical significance (χ2=42.93, 14.46, P<0.01). The healing time was (8.78±4.27) d in the observation group and (10.46±3.99) d in the control group with significance(t=2.88, P< 0.05). The healing rates of Arnebiae oil sacrococcygeal region, hips, legs and other parts were 87.96%(95/108), 9/10, 12/16, 9/9, significantly higher than those of the control group, 46.43%(39/84), 6/12, 3/9, 9/15, the difference had statistical significance (χ2=4.02-44.35, P<0.05). Conclusion Arnebiae oil com-bined with the overall care can improve the rate of wound healing in aged pressure ulcer, which is suitable for clinical application.
