Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can cause acute respiratory distress syndrome, hypercoagulability, hypertension, and multiorgan dysfunction. Effective antivirals with safe clinical profile are urgently needed to improve the overall prognosis. In an analysis of a randomly collected cohort of 124 patients with COVID-19, we found that hypercoagulability as indicated by elevated concentrations of D-dimers was associated with disease severity. By virtual screening of a U.S. FDA approved drug library, we identified an anticoagulation agent dipyridamole (DIP) , which suppressed SARS-CoV-2 replication . In a proof-of-concept trial involving 31 patients with COVID-19, DIP supplementation was associated with significantly decreased concentrations of D-dimers ( < 0.05), increased lymphocyte and platelet recovery in the circulation, and markedly improved clinical outcomes in comparison to the control patients. In particular, all 8 of the DIP-treated severely ill patients showed remarkable improvement: 7 patients (87.5%) achieved clinical cure and were discharged from the hospitals while the remaining 1 patient (12.5%) was in clinical remission.

Objective To survey the survival status, functional status, marital status and the present situation of the survival patients with spinal cord injury 40 years after Tangshan earthquake. Methods From February to May, 2016, a total of 216 patients with spinal cord injury were surveyed with questionnaire, in which 139 cases lived centralized and 77 cases lived scattered. The questionnaire was self-designed and included eleven items and 51 questions, which related to ability of daily life, marital status, employment status and socioeconomic status and so on. Results A total of 960 (25.15%) patients with spinal cord injury survived 40 years after Tangshan earthquake. In 216 surveyed pa-tients, the employment rate was 9.3%, the married rate was 53.2%, and 44.9%earned less than 500 yuan every month. The incidence was 25.9%for pressure score, 50.50%for neuralgia (severe pain accounted for 23.51%), and 19.40%for urinary tract stones. 56%of patients could take their own basic self-care. Conclusion There were many problems such as high complication rate, low employment rate and poor economic condition in the spinal cord injury group 40 years after Tangshan earthquake.

Objective To study the effects of heat shock treatment of rat bone marrow mesenehymal stem cells(MSCs),the apoptosis ratio of treated-cells under low serum condition and the treated-cells transplantation on left ventricular function in rats with myocardiaIinfarction.Methods MSC8 were heat-treated under 42℃for 30 min,then the heat shock protein-70(HSP-70)was detected bv Western blot.The apoptosis ratio of heat-treated MSCs under low serum condition was tested by Annexin kit.The treated-MSCs labeled with Dil were transplanted into infarcted myocardium and 8 weeks later,the cardiac function of rats in each group was evaluated by echocardiography and cardiac catheterization.Results The immunophenotype of heat-treated MSCs did not vary,Western blot confirmed a higher level expression of HSP-70 in the treated-MSCs group as compared with that in the control group.The early apoptosis ratio was lower in treated-MSCs measured by flow cytometry with annexin staining than that of MSCs when cultured with low serum medium.After 8 weeks,LVEF,LVSP,+dp/dtmax,and-dp/dtmax were significantly higher,and the LVEDP was significantly lowar in heat-treated MSCs transplantation group than that in the control group.Conclusions Heat shock pretreatment of MSCs enhances the tolerance of MSCs to low serum medium,whereas does not lcad to the change of the cell immunophenotype.Transplantation of heattreated MSCs might improve the cardiac function in a rat myocardialinfarction model.

Objectives To study the current prevalence and recent epidemiological changes of Helicobacter pylori (H. pylori) infection among children and adults residing in regions with high ( Muping, Shandong) and low (Yanqing, Beijing) incidence of gastric cancer in China. Methods A total of 2065 asymptomatic children aged 8-15 years and adults aged 40-79 years in the above two regions were examined from May to July 2006. The data obtained in early 1990s in the same two areas and those of 11 656 patients undergoing endoscopy in our hospital in 1991 and 2006 were also collected and studied. Results The prevalence ofH. pylori infection in Muping was significantly higher than that in Yanqing among both children (37.69% vs25.58%, P<0.001) and adults (50.95% vs41.35%, P < 0. 01 ). From 1991 to 2006 H. pylori prevalence among children aged 8-10 years decreased in Muping (60. 00% vs 32. 07% , P < 0.001), but not in Yanqing (24.06% vs 19.10%, P > 0. 05 ) . A significant decrease in H. pylori prevalence among adults in both regions was observed when the results of 2006 were compared with the data obtained in 1990 in Muping (50.95% vs 73.78% , P < 0. 001 ) and in 1992 inYanqing (41.35% vs 55. 35% , P < 0. 01 ) . The detected rate of H. pylori infection in patients undergoing endoscopy in our hospital decreased from 51. 88% in 1991 to 33. 59% in 2006 (P <0. 001). Conclusions The prevalence of H. pylori infection is significantly higher in areas with a high incidence of gastric cancer in China as compared with that in areas with a low incidence of gastric cancer among both children and adults. H. pylori infection may be a risk factor in gastric carcinogenesis. In the past decade or more, H.pylori infection rates have decreased in Chinese population.

Objective To investigate the incidence of peptic ulcer (duodenal ulcer and gastric ulcer) and the development of Helicobacter pylori (Hp) infection in the population during 10 years after Hp eradication.Methods Subjects were chosen from general population and performed endoscopy.Among them,the individuals confirmed to be Hp positive were randomly divided into treatment group and placebo group.The patients in treatment group received OAC triple therapy (omeprazole 20 mg,clarithromycin 500 nag and amoxicillin 1000 re.g,twice daily) for one week.After that,both groups continuously followed up by endoscopy during at 1st,5th,8th and 10th year for incidence and relapse of peptic ulcer as well as status of Hp infection.The patients in treatment group were examined by 13C-UBT for Hp eradication one month after the completion of treatment.Results At the 1st year,the incidence of peptic ulcer between the treatment group and placebo group were 3.7% and 12.85% (P=0.0002),respectively.At the 5th year,they were 5.86% and 14.93% (P=0.0017),respectively.At the 8th year,they were 4.4% and 9.39% (P = 0.044),respectively.The incidence of peptic ulcer of the treatment group significantly decreased after the eradication therapy compared to the placebo group.After the eradication,at the 1st year,the recurrence rates were 3.70% and 38.1% between the treatment group and the placebo group (P=0.0027).At the 5th year,they were 14.81% and 42.86% (P=0.03).At 8th year,they were 14.81 and 47.62% (P=0.03),respectively.At the 10th year,they were 25.93% and 57.14% (P=0.028).Then the recurrence rates of the treatment group significantly decreased compared to the placebo group.During the 10-year follow up study,the rate of Hp reinfection after a successful eradication in the treatment group was high,and it was 46.4% at the 10th year.Conclusion Both the incidence and recurrence of peptic ulcer significantly decreased after Hp eradication.It is necessary of Hp eradication in patients with peptic ulcer.Hp reinfection after a successful eradication is more frequent.
