RESUMEN
BackgroundSARS-CoV-2-caused coronavirus disease (COVID-19) is posing a large casualty. The features of COVID-19 patients with and without pneumonia, SARS-CoV-2 transmissibility in asymptomatic carriers, and factors predicting disease progression remain unknown. MethodsWe collected information on clinical characteristics, exposure history, and laboratory examinations of all laboratory-confirmed COVID-19 patients admitted to PLA General Hospital. Cox regression analysis was applied to identify prognostic factors. The last follow-up was February 18, 2020. ResultsWe characterized 55 consecutive COVID-19 patients. The mean incubation was 8.42 (95% confidence interval [CI], 6.55-10.29) days. The mean SARS-CoV-2-positive duration from first positive test to conversion was 9.71 (95%CI, 8.21-11.22) days. COVID-19 course was approximately 2 weeks. Asymptomatic carriers might transmit SARS-CoV-2. Compared to patients without pneumonia, those with pneumonia were 15 years older and had a higher rate of hypertension, higher frequencies of having a fever and cough, and higher levels of interleukin-6 (14.61 vs. 8.06pg/mL, P=0.040), B lymphocyte proportion (13.0% vs.10.0%, P=0.024), low account (<190/{micro}L) of CD8+ T cells (33.3% vs. 0, P=0.019). Multivariate Cox regression analysis indicated that circulating interleukin-6 and lactate independently predicted COVID-19 progression, with a hazard ratio (95%CI) of 1.052 (1.000-1.107) and 1.082 (1.013-1.155), respectively. During disease course, T lymphocytes were generally lower, neutrophils higher, in pneumonia patients than in pneumonia-free patients. CD8+ lymphocytes did not increase at the 20th days after illness onset. ConclusionThe epidemiological features are important for COVID-19 prophylaxis. Circulating interleukin-6 and lactate are independent prognostic factors. CD8+ T cell exhaustion might be critical in the development of COVID-19.
RESUMEN
Objective:To investigate the expression of eukaryotic translation initiation 2α (p-elF2α) and activated translation factor 4 (ATF4) in liver tissues of patients with chronic hepatitis B and their correlation with liver fibrosis.Methods:From Jan.2016 to Jan.2019, 158 cases of chronic hepatitis B patients were enrolled in our hospital. The expression levels of p-elF2α and ATF4 in different stages of liver fibrosis were evaluated by hematoxy-eosin (HE) and immunohistochemical staining, and the correlation was analyzed by Spearman rank correlation.Results:The pathological results of liver specimens showed that there were 19 normal controls (S0), 29 S1, 42 S2, 35 S3 and 33 S4 in each stage of fibrosis. The levels of p-eIF2α and ATF4 in fibrosis group were significantly higher than those in normal control group ( P< 0.001). Additionally, the levels of p-eIF2α and ATF4 in different stages of fibrosis were significantly different. The grade of hepatic fibrosis was positively correlated with the scores of p-eIF2α and ATF4 staining in liver tissues, and the correlation coefficients were 0.473 and 0.422 respectively ( P< 0.05). Conclusions:Hepatic fibrosis in patients with chronic hepatitis B is positively correlated with p-eIF2α and ATF4. p-eIF2α-ATF4 pathway may involve in the process of chronic hepatitis B-induced hepatic fibrosis.

RESUMEN
The paper reviewed the history and characteristics of the public hospital reform in China. Based on the theories of corporate governance, it made analysis and comments on existing roadblocks and reform attempts in such hospitals, proposing a public hospital governance model in line with the general reforms made in China's healthcare system sector.
RESUMEN
A description of the concept,origin and development,and key contents of the system safety theory,and an analysis of the presence and future of China's medical safety management,holding that such a theory enjoys a promising perspective in medical safety managemenL Medical safety management needs to follow such a theory as fl guideline,and its principles to set system safety objectives,and to determine the scope of the safety system_By building a comprehensive feedback mechanism,clarifying the responsibility borders and advocating a safety culture,medical safety management can be significantly upgraded.
RESUMEN
Objective To address medical relief algorithm in earthquake center by analyzing triage and transfer of casualties in the quake-hit center Yingxiu town in the wake of the 5·12 Wenchuan earthquake.Method According to the actual hard working conditions and rule of CBASHPLAN,the locale was derided into triage area,minor wounds area,severe wounds area and transfer area.Medical team coming from Soulhwest Hospital,the Third Military Medical University was derided into several groups. Triage, treatment and transfer of casualties well arranged. Results A total of 415 victims was treated by our medical team in early three days.Of these victims,251 were severe injuned,153 were debrided,12 were decompression with cutting open the wound because of their oseofascial canpartment syndrome,and 317 casualties were transferred by helicopters.No victim died during treatment and transfer at quake-stricken region.The whole work was proceeded in good order and efficiently.Conclusions Triage and transfer of casualties scientifically allowing for the capability of medical relief and the sufficiency of medical resources are very important to deal with batches of casualties in quake-stricken region.
