[Objectives]To investigate the clinical effect of Yinhuang Qingfei capsules in the treatment of asymptomatic and mild/common severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection.[Methods]A total of 362 patients with SARS-CoV-2 infection were divided into the treatment group with 242 patients and control group with 120 patients according to their treatment regimen.The patients in the control group were given standard treatment regimen and those in the treatment group were given Yinhuang Qingfei capsules in addition to the treatment in the control group.The two groups were observed in terms of average length of hospital stay,mean time for nucleic acid clearance,TCM syndrome score,and progression to severe/critical illness,and clinical outcome was compared between the two groups.[Results]There was a significant difference in the overall response rate between the treatment group and the control group[97.52%(236/242)vs 95.00%(114/120),P<0.05].Compared with the control group,the treatment group had significantly shorter length of hospital stay and time for nucleic acid clearance(P<0.05).After 7 days of treatment,both groups had a significant change in TCM syndrome score,and there was a significant difference in TCM syndrome score between the two groups(P<0.05);after 15 days of treatment,both groups had a TCM syndrome score of 0.Progression to severe/critical illness was not observed in either group.[Conclusions]Compared with the standard treatment regimen alone,standard treatment regimen combined with Yinhuang Qingfei capsules can effectively shorten the length of hospital stay and time for nucleic acid clearance and improve TCM symptoms in patients with asymptomatic and mild/common SARS-CoV-2 infection. 展开更多

Sleep disturbances are among the most prevalent neuropsychiatric symptoms in individuals who have recovered from severe acute respiratory syndrome coronavirus 2 infections.Previous studies have demonstrated abnormal brain structures in patients with sleep disturbances who have recovered from coronavirus disease 2019(COVID-19).However,neuroimaging studies on sleep disturbances caused by COVID-19 are scarce,and existing studies have primarily focused on the long-term effects of the virus,with minimal acute phase data.As a result,little is known about the pathophysiology of sleep disturbances in the acute phase of COVID-19.To address this issue,we designed a longitudinal study to investigate whether alterations in brain structure occur during the acute phase of infection,and verified the results using 3-month follow-up data.A total of 26 COVID-19 patients with sleep disturbances(aged 51.5±13.57 years,8 women and 18 men),27 COVID-19 patients without sleep disturbances(aged 47.33±15.98 years,9 women and 18 men),and 31 age-and gender-matched healthy controls(aged 49.19±17.51 years,9 women and 22 men)were included in this study.Eleven COVID-19 patients with sleep disturbances were included in a longitudinal analysis.We found that COVID-19 patients with sleep disturbances exhibited brain structural changes in almost all brain lobes.The cortical thicknesses of the left pars opercularis and left precuneus were significantly negatively correlated with Pittsburgh Sleep Quality Index scores.Additionally,we observed changes in the volume of the hippocampus and its subfield regions in COVID-19 patients compared with the healthy controls.The 3-month follow-up data revealed indices of altered cerebral structure(cortical thickness,cortical grey matter volume,and cortical surface area)in the frontal-parietal cortex compared with the baseline in COVID-19 patients with sleep disturbances.Our findings indicate that the sleep disturbances patients had altered morphology in the cortical and hippocampal structures during the acute phase of infection and persistent changes in cortical regions at 3 months post-infection.These data improve our understanding of the pathophysiology of sleep disturbances caused by COVID-19. 展开更多

Background Severe acute respiratory syndrome (SARS) is characterized by both an atypical pneumonia and efficient nosocomial transmissin. However,it remains unknown whether the infectivity and the virulence of the pathogen will change throughout the successive transmission. This study was conducted to compare the clinical features and management regimens of patients with SARS among the multiple generations from nosocomial transmission initiated by a super-spreader. Methods The clinical data of 84 epidemiologically-linked SARS patients from a hospital outbreak were retrospectively studied. All patients,in whom a clear-cut transmission generation could be noted,had a direct or indirect exposure to the index patient and the epidemic successively propagated through the multiple generations of cases within a short period of time. Results There were 66 women and 18 men with mean age of (29.2 ± 10.3) years in this cluster;and 96.4% of whom were health care workers. Detailed contact tracing identified 35 (41.7%) first-generation cases,34 (40.5%) second-generation cases,and 15 (17.8%) third-generation cases. No statistical differences among the multiple generations of transmission were found in terms of age,gender,incubation period and length of hospital stay. With the advanced transmission generations,the initial temperature lowered,the number of cases with dry cough decreased. There were no statistical differences in the peak temperature and duration of fever,other accompanying symptoms,leucopenia;however,the time from initial pulmonary infiltrates to radiographic recovery shortened ( P <0.05). No differences were found in maximum number of lung fields involved,duration from the onset of fever to the occurrence of pulmonary infiltrates and time from the initial pulmonary infiltrate to its peak among the multiple transmission generations ( P >0.05). No statistical differences were found in modes of oxygen therapy and sorts of antibiotics prescribed among the various transmission generations ( P >0.05);however, as with the advanced transmission generations,the number of cases prescribed with methylprednisolone,human γ-globulin,interferon-α,antiviral drugs (oral ribavirin or oseltamivir) increased ( P <0.05) and time from admission to starting these medication shortened ( P <0.05). Conclusions There is no evidence that SARS infection will evolve or transmit within a fashion that permits it to become less powerful throughout the successive transmission within a short time. 展开更多

The severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has triggered a widespread outbreak since December 2019.The SARS-CoV-2 infection-related illness has been dubbed the coronavirus disease 2019(COVID-19)by the World Health Organization.Asymptomatic and subclinical infections,a severe hyperinflammatory state,and mortality are all examples of clinical signs.After attaching to the angiotensin converting enzyme 2(ACE2)receptor,the SARSCoV-2 virus can enter cells through membrane fusion and endocytosis.In addition to enabling viruses to cling to target cells,the connection between the spike protein(S-protein)of SARS-CoV-2 and ACE2 may potentially impair the functionality of ACE2.Blood pressure is controlled by ACE2,which catalyzes the hydrolysis of the active vasoconstrictor octapeptide angiotensin(Ang)II to the heptapeptide Ang-(1-7)and free L-Phe.Additionally,Ang I can be broken down by ACE2 into Ang-(1-9)and metabolized into Ang-(1-7).Numerous studies have demonstrated that circulating ACE2(cACE2)and Ang-(1-7)have the ability to restore myocardial damage in a variety of cardiovascular diseases and have antiinflammatory,antioxidant,anti-apoptotic,and anti-cardiomyocyte fibrosis actions.There have been some suggestions for raising ACE2 expression in COVID-19 patients,which might be used as a target for the creation of novel treatment therapies.With regard to this,SARS-CoV-2 is neutralized by soluble recombinant human ACE2(hrsACE2),which binds the viral S-protein and reduces damage to a variety of organs,including the heart,kidneys,and lungs,by lowering Ang II concentrations and enhancing conversion to Ang-(1-7).This review aims to investigate how the presence of SARS-CoV-2 and cACE2 are related.Additionally,there will be discussion of a number of potential therapeutic approaches to tip the ACE/ACE-2 balance in favor of the ACE-2/Ang-(1-7)axis. 展开更多

In the past ten years, we had experienced a series of .emerging severe acute respiratory infections (SARI).Some of them became serious public health emergent events, such as severe acute respiratory syndrome (SARS) and novel A/H7N9 avian influenza. Tracing back to 2003, SARS originated from Guangdong province and spread to 29 countries and regions until it was completely controlled. Out of 8 096 probable SARS cases world-wide, 774 patients died; the mortality was 9.6%.1 There were 5 327 patients with SARS in China, and 1 002 (19%) of them were health care workers (HCW). Nearly all the HCW got hospital acquired infection since there was no efficient preventive and protective system. 展开更多
