ABSTRACT

Objective:To investigate high resolution CT (HRCT) manifestations and clinical features of patients infected with the novel coronavirus B.1.617.2 variant.Methods:A total of 125 patients with the novel coronavirus B.1.617.2 variant in Guangzhou Eighth People′s Hospital from May 21 to June 9, 2021 was enrolled. There were 52 males and 73 females, aged from 1 to 92 years old with a median age of 47 year. The clinical features and HRCT characteristics were analyzed retrospectively.Results:Of the 125 patients, the main clinical manifestations were fever in 54 patients, cough in 50 patients, pharyngeal discomfort in 39 patients, and diarrhea in 5 patients. HRCT showed pneumonia in 96 cases, which predominantly had ground-glass opacities in 92 cases, ground-glass opacities combined with local consolidation in 22 cases, consolidation in 11 cases, intralobular interstitial thickening in 51 cases, centrilobular structural thickening in 23 cases, and cord-like lesions in 33 cases. One patient had pleural effusion, and no enlarged lymph nodes were observed in all patients. The lesions were distributed in the subpleural and/or peripheral lung in 96 cases and along the bronchovascular bundle (middle and inner zone) in 24 cases. The time interval from onset to positive HRCT was 3 (1, 4) days in 96 patients with pneumonia on HRCT. HRCT showed absorption after the imaging findings reaching the peak in 20 patients, and the time interval between the first positive HRCT findings and the peak imaging was 6 (3, 7) days in these 20 patients.Conclusions:The novel coronavirus B.1.617.2 variant has a strong infectivity, short viral latency. Lung injury is decreaseel. People of all ages are susceptible and the diseasemay have rapid pnegression. HRCT mainly shows ground glass opacities, which are more common in subpleural and/or in the lung periphery, with interlobular thickening.

ABSTRACT

Objective:To investigate the initial high resolution CT (HRCT) manifestations and clinical features of imported COVID-19 in Guangzhou.Methods:A retrospective analysis of 91 COVID-19 patients admitted to the Guangzhou Eighth People's Hospital from January 22 to 30, 2020 was performed including 39 males and 52 females, with a median age of 50 (33-62) years,then their clinical features and HRCT characteristics were analyzed.Results:The main clinical presentations included fever in 70 cases and cough in 57 cases(mainly dry cough in 39 cases). The first time HRCT showed that 24 cases with COVID-19 were normal, however other 67 cases were abnormal. The ground glass opacity in the lung on HRCT was found in 65 cases, including 64 cases with dilated blood vessel crossing the lesion, 50 cases with thickened adjacent pleura, and 47 cases with thickening of interstitial septum. The patchy opacity was seen in 42 cases, and no enlarged lymph nodes were observed in all patients. As for the lesion distribution, there were two cases with bilateral diffuse changes, 57 cases with multiple lesions, 8 cases with the lesion in only one lobe. The lesions were mainly located under the pleura area in 46 cases, including 39 cases in the lower lobe and other 7 cases in the upper lobe. And there were 13 cases without characteristic distribution in the lung.Conclusion:The initial images of COVID-19 in Guangzhou mainly showed multiple ground glass opacity, which were mostly seen in the subpleural and lower lung fields, most of them with thickened pulmonary interstitium. Guangzhou has a higher proportion of COVID-19 patients with mild and general patients, and some confirmed patients show negative HRCT for the first time. Patients without HRCT changes should be reviewed in a timely manner.

ABSTRACT

Objective: To investigate the clinical efficacy and adverse effects of alternating triple therapy with CHOP-B, MINE and GELOXD in the treatment of primary peripheral T-cell lymphomas (PTCLs) by a single-center study. Methods: From January 2012 to December 2016, the pathological data of fifty-four patients with PTCLs admitted to Hunan Cancer Hospital were enrolled in this retrospective analysis.The last follow-up period was up to June 20, 2018. All patients underwent alternating triple therapy regimens with CHOP-B, MINE and GELOXD, and then the complete clinical data were collected. Survival was analyzed by Kaplan-Meier method. Multivariate COX analysis was performed to explore the related factors affecting prognosis. Results: Among 54 patients with PTCLs, twenty-six patients were diagnosed with peripheral T-cell lymph-non-specific lymphoma (PTCL-NOS), while there is one patient with angioimmunoblastic lymphoma, fifty patients with anaplastic lymphoma kinase positive anaplastic large cell lymphoma (ALK+ALCL), and twelve patients with ALK negtive ALCL (ALKALCL). The stage of EI-IV was demonstrated in 77.8% cases, the elevated lactate dehydrogenase (LDH) was observed in 40.7% of the patients, and 31.5% of the patients were in the lower risk group of prognostic index for PTCL-NOS (PIT) score. Following the initial therapy, 20 of 54 (37.0%) cases achieved complete remission, 22 (40.7%) achieved partial remission, 1 (1.9%) had stable disease, and 11 (20.4%) had disease progression. The objective remission rate (ORR) was 77.3%. The 3-year progression-free survival (PFS) and overall survival (OS) were 58.3% and 71.7%, respectively. The median PFS was 41.3 months, but the median OS was not achieved. Univariate analysis showed that age, bone marrow involvement, high body mass index (BMI), elevated LDH, PIT score, and clinical stage (El-IV)were associated with OS. Multivariate analysis showed PIT score ≥ 2(P < 0.001) and BMI ≥ 24 kg/m2 (P = 0.025) were the independent prognostic factor for the patients with PTCLs. Haemocytopenia was the predominant adverse effect. The incidence of degree 3-4 leukopenia in CHOP-B, MINE, GELOXD regimens was 4.6%, 10.1% and 17.5%, respectively; the incidence of degree 3-4 anemia was 4.6%, 5.1% and 0.9%, respectively; the incidence of degree 3-4 thrombocytopenia was 2.7%, 0.0% and 0.9%, respectively. Conclusion: The combination of CHOP-B, MINE and GELOXD regimens is efficacy and safety in the treatment of PTCLs, so it is worth popularizing in more cases.

ABSTRACT

Objective To systematically evaluate the effects of mechanical chest compression (CC) combined with manual CC and single-manual CC on the outcome indexes of cardiopulmonary resuscitation (CPR) for patients with in-hospital cardiac arrest (IHCA). Methods The relevant publicly published literatures about the effects of mechanical CC combined with manual CC and single-manual CC on the outcome of CPR were searched by using the following Chinese keywords for retrieval: "cardiac arrest, asystole, sudden death, artificial recovery, artificial press, artificial CC, unarmed CPR, unarmed resuscitation, unarmed compressions, unarmed chest compressions, unarmed, artificial, resuscitation instrument, resuscitation machine, resuscitator, CPR, LUCAS, Autopulse, Thumper, MSCPR-1A"in databases such as China Biomedical Literature (CBM), VIP, Wanfang, and China National Knowledge Internet (CNKI) from their dates of foundation to March 11, 2019, and using the following key words in English "heart arrest, cardiac arrest, cardiopulmonary arrest, Cardiopulmonary Resuscitation, Resuscitation, Cardio-Pulmonary Resuscitation, CPR, compression, mechanical, automatic, automated, load distributing band, LBD, Autopulse, LUCAS" to retrieve all the published articles especially concerning the topics on the application effects of mechanical combined with manual CC for IHCA patients' CPR in the America National Library database (PubMed), Excerpta Medica (EMbase), Web of Science, and Cochrane Library from the establishment of the databases to March 11, 2019. The indexes of outcomes included return of spontaneous circulation (ROSC) rate, survival rate after hospital discharge and incidence of complications. The literatures were extracted independently by two reviewers, the qualities of the included randomized controlled trials (RCTs) were evaluated according to the Cochrane bias risk assessment tool, and the qualities of the included observational studies were evaluated according to the literature quality assessment form (NOS). Meta analysis was performed by using RevMan 5.3 software, and publication bias was assessed by using funnel plot. Results Twenty-one studies were enrolled, including 11 RCT articles and 10 observational studies; there were 2 005 participants. The results of this Meta-analysis showed that compared with manual CC, the ROSC rate and after discharge survival rate of IHCA patients were obviously higher in combined CC group [ROSC: odds ratio (OR) = 2.50, 95% confidence interval (95%CI) = 2.03-3.09, P < 0.000 01; discharge survival rate: OR = 2.71, 95%CI = 1.91-3.85, P < 0.000 01]; the incidence of complications of combined CC was lower than that in single manual CC (OR = 0.30, 95%CI = 0.13-0.68, P = 0.004). The funnel plots indicated that there was no apparent bias in the ROSC; because the enrolled studies were relatively few, it was difficult to evaluate the symmetrical characteristics of the funnel plots for discharge survival rate and the complication rate. Conclusions For IHCA patients, combined CC can improve ROSC, discharge survival rate, and reduce the occurrence of complications. It is suggested that during the actual rescue of IHCA patients, it is better to use combined CC, that is to say, manual CC should be adopted immediately in the early stage and then replace the mechanical CC device as soon as possible.

ABSTRACT

Objective To comprehensively evaluate and compare the resuscitation efficacy of chest-compression-only cardiopulmonary resuscitation (CCPR) and standard cardiopulmonary resuscitation (SCPR) for patients with out-of-hospital cardiac arrest (OHCA). Methods Databases such as PubMed, Embase, Ovid, Cochrane Library, Wanfang, CNKI, VIP, CBM were searched from the date of their foundation to March 2nd 2018, and the studies on the difference of effects between CCPR and SCPR for patients with OHCA were retrieved. The outcomes included the return of spontaneous circulation (ROSC) rate, survival to hospital discharge, neurological function completion rate. Two reviewers independently screened the literature meeting the inclusion criteria, independently collected information and evaluated the literature quality. Meta-analysis was conducted using RevMan 5.3 software, and sensitivity analysis was conducted by selecting model analysis method and removing single research method. Funnel plot was used to evaluate publication bias. Results A total of 10 cohort studies were included, including 174 163 patients with OHCA, of which 95 157 undergone CCPR and 79 006 undergone SCPR. The scores of the Newcastle-Ottawa scale (NOS) were 8-9, indicating that the quality of the literatures included was high. It was shown by the Meta-analysis that CCPR had the higher rate of survival to hospital discharge [relative risk (RR) = 1.04, 95% confidence interval (95%CI) = 1.00-1.08, P = 0.04] and neurological function completion (RR = 1.11, 95%CI = 1.06-1.17, P < 0.000 1) than SCPR, but there was no significant difference in ROSC rate between the two groups (RR = 1.01, 95%CI = 0.98-1.04, P = 0.52). In the subgroup, there was no statistical significance between CCPR and SCPR in the rate of survival to hospital discharge in cardiac OHCA patients (RR = 1.13, 95%CI = 0.82-1.57, P = 0.45). However, in non-cardiac OHCA group, SCPR showed more benefits than CCPR in improving the rate of survival to hospital discharge (RR = 0.88, 95%CI = 0.80-0.96, P = 0.004). The above analysis results were consistent in the fixed effect model and random effect model, indicating that the results were reliable and stable. It was shown by the funnel plot that most of the studies were left-right inverted funnel type, indicating a low publication bias. However, the bias could not be completely excluded due to the small number of included literatures. Conclusions For patients without OHCA etiological classification, CCPR was not less than SCPR in improving ROSC rate, discharge survival rate and good neurological function, and CCPR was more advantageous in learning and the willingness of bystanders to implement. However, when non-cardiogenic OHCA could be identified, SCPR should be recommended when conditions permit.

ABSTRACT

Based on the capacitance coupling principle, we studied a capacitive way of non-contact electrocardiogram (EGG) monitoring, making it possible to obtain ECG on the condition that a patient is habilimented. Conductive fabric with a good electrical conductivity was used as electrodes. The electrodes fixed on a bed sheet is presented in this paper. A capacitance comes into being as long as the body gets close to the surface of electrode, sandwiching the cotton cushion, which acts as dielectric. The surface potential generated by heart is coupled to electrodes through the capacitance. After being processed, the signal is suitable for monitoring. The test results show that 93.5% of R wave could be detected for 9 volunteers and ECG with good signal quality could be acquired for 2 burnt patients. Non-contact ECG is harmless to skin, and it has advantages for those patients to whom stickup electrodes are not suitable. On the other hand, it is convenient to use and good for permanent monitoring.

ABSTRACT

Primary biliary cirrhosis (PBC) is an autoimmune liver disease which progresses slowly, and its pathogenesis remains unclear. A total of 29 papers reporting the risk factors for PBC from different perspectives were obtained through Google Scholar search and screening, consisting of 19 reviews and 10 reports of investigational studies. By summarizing the objects and methods in 10 investigational studies and the conclusions of all the 29 papers, the induction mechanism of risk factors for PBC is clarified, and the control strategy for PBC is put forward. Since the literature included was studies on foreign populations conducted by foreign scholars, the applicability of these findings in China should be further investigated.
