Artificial intelligence & intelligent medical service mainly covers artificial-intelligence-assisted diagnosis, artificial-intelligence medical decision-making, and artificial-intelligence-assisted new drug research & development. Internet of things & internet hospital mainly covers internet hospitals, internet care, cloud pharmacies, and medical imaging clouds. Intelligent hospitals mainly cover intelligent clinics, intelligent wards, and intelligent management. The revolution trends count on not only techniques such as 5G, but also the support and cooperation of the government and society. The risk of information and data leak needs attention.
Objective To compare the effects of rivaroxaban and enoxaparin on hidden blood loss after total hip arthroplasty (THA). Methods A retrospective analysis was made on the clinical data of 76 patients (93 hips) with avascular necrosis of the femoral head who underwent primary THA between June 2009 and January 2012. After operation, 10 mg rivaroxaban was used at 6-10 hours for 14 days in 44 cases (54 hips) (rivaroxaban group) and 4 000 U enoxaparin at 12 hours for 14 days in 32 cases (39 hips) (enoxaparin group). There was no significant difference in age, gender, weight, height, disease duration, grade of avascular necrosis of the femoral head, and lesion hips between 2 groups (P gt; 0.05). The total blood loss, dominant blood loss, hidden blood loss, and percentage of hidden blood loss were calculated according to the formula. The bleeding events were recorded within 35 days after operation. Results The total blood loss was (1 509.56 ± 325.23) mL; the dominant blood loss was (928.09 ± 210.50) mL; the hidden blood loss was (581.47 ± 215.01) mL; and the percentage of hidden blood loss was 37.88% ± 10.42% in the rivaroxaban group. The total blood loss was (1 521.38 ± 516.49) mL; the dominant blood loss was (917.50 ± 378.73) mL, the hidden blood loss was (603.88 ± 377.15) mL, and the percentage of hidden blood loss was 38.18% ± 18.33% in the enoxaparin group. There was no significant difference in the above indicators between 2 groups (P gt; 0.05). The incidence of bleeding event was 9.1% (4/44) in the rivaroxaban group and was 3.1% (1/32) in the enoxaparin group, showing no significant difference (χ2=1.073, P=0.390). Conclusion There is no significant difference in the risk of hidden blood loss and incidence of bleeding event for primary THA between the rivaroxaban and the enoxaparin use.
Objective To investigate the characteristics of blood pressure and coronary artery impairment in patients with essential hypertension (EH) combining coronary heart disease (CHD). Methods A total of 358 patients with EH combining CHD and other 144 patients with CHD were measured with ambulatory blood pressure monitoring (ABPM), and the parameters of ambulatory blood pressure were analyzed. All the patients underwent coronary angiography. The severity of coronary artery stenosis was evaluated in accordance with the number of impaired arteries. Results Compared to the patients with simplex CHD, those with EH combining CHD had much heavier artery stenosis and more diffuse lesions, with significant differences (χ2=6.03, P=0.019). The 24h systolic blood pressure (SBP), day SBP, night SBP, 24h pulse pressure (PP), day PP and night PP were higher in the patients with EH combining CHD compared to those of the patients with simplex CHD (The t values were 2.580, 2.045, 2.675, 2.037, 2.601, and 1.995, respectively, while the P values were 0.015, 0.037, 0.009, 0.041, 0.017, and 0.047, respectively). Conclusion Compared to the patients with simplex CHD, the patients with EH combining CHD suffer from much severe coronary artery impairment, so a good controlling of blood pressure is advisable to improve the coronary artery impairment for the patients with EH combining CHD.
Targeted initiatives of West China Hospital of Sichuan University to cope with coronavirus disease 2019 epidemic in three stages were summarized, including “three reconstructions” to mobilize in pre-epidemic stage, “three earlies” strategy to precisely treat critically ill patients in epidemic stage, and “three orderlies” to resume hospital operation in post-epidemic stage. The development of comprehensive hospitals in China after the epidemic was also discussed. It’s recommended to continuously strengthen the role of emergency response, early warning, comprehensive treatment, high-level talent training, international exchange, regional leadership, and collaborative innovation, in response to the shortcomings exposed in the epidemic.
ObjectiveTo describe clinical significance of eosinopenia in patients with coronavirus disease 2019 (COVID-19).MethodsThis was a retrospective study conducted in three tertiary hospitals from Anhui province, China. A total of 59 patients with COVID-19 were consecutively reviewed from January 23, 2020 to March 10, 2020.ResultsThe median age of patients with COVID-19 was 39 years old, and 32 were male, 30 with eosinopenia. Cough, sputum and fatigue were more common symptoms in eosinopenia patients compared with non-eosinopenia patients. The counts of blood lymphocytes (median: 101 cells/μL) in eosinopenia patients were significantly less than those of non-eosinopenia patients (median: 167 cells/μL, P<0.001). COVID-19 patients with eosinopenia had a higher proportion of corticosteroids therapy than patients with non-eosinopenia (50.0% vs. 13.8%, respectively, P=0.005). Decreased blood lymphocytes count was an independent risk factor for eosinopenia in COVID-19 patients (odds ratio 6.566, 95%CI 1.101 - 39.173, P=0.039).ConclusionsBlood eosinopenia is frequent in COVID-19 patients. Patients with eosinopenia have different clinical features compared to patients with non-eosinopenia. Decreased lymphocyte count is an independent risk factor for eosinopenia in COVID-19 patients.
The May 12 8-magnitude earthquake caused damage to 87.7% of the health systems in the worst-hit Mianyang areas with 326 casualties and the direct economic loss of RMB 3 124 billion. Within 30 minutes after the earthquake, the Mianyang headquarters for earthquake disaster relief and the Mianyang public health headquarters for medical rescue and treatment were organized. Five medical teams were sent to Beichuang County, the worst-hit Mianyang area within four hours after the earthquake. A total of 22 947 wounded and sick were delivered to local hospitals after simple triage and rapid treatment through three station. By June 30, the Mianyang medical organisation had received 379 600 person times and admitted 21628 inpatients in total, including 2 772 severely-wounded (including 146 with limbs amputated and 846 dead during the stay). Since May 17, 3381 wounded had been transferred to 14 provincial and city-level hospitals across China. On June 20, the Mianyang Rehabilitation Center for wounded and sick people was established and received 156 rehabilitation inpatients and cured 32 ones. Together with the medical team for psychological intervention, they provided psychological support for victims for over 70 000 person times. Within two hours after the earthquake, the Mianyang Organisation for Health and Epidemic Control and Prevention launched the emergency response plan for major natural disasters, prepared and improved the technical scheme for disease prevention after the earthquake. The organisation rapidly sent out emergency teams for disease control and prevention and completed the following tasks: disinfection and burial of corpses and disposal of carcasses, monitoring of the water quality and epidemics, disinfection of environmental ruins, epidemic control in resettled areas, precaution of the secondary disasters caused by the earthquake and conduction of large-scale health education. The emergency command system for medical rescue and disease control and prevention in the worst-hit Mianyang areas after Wenchuan Earthquake integrated resources, carried out the unified command and responded rapidly. Moreover, the headquarter of medical relief coordinated and orderly unified the governmental and non-governmental organizations, which achieved good performance for both medical relief and anti-epidemic. The experience of earthquake medical relief will benefit the post-disaster reconstruction, as well as the establishment of national and regional emergency response systems.
The Wenchuan Earthquake caused severe injuries and deaths as well as subsequent serious potential risks to public health and hygiene in the worst-hit areas. There were 16 casualties in the Mianyang CDC system and the township amp; county CDC networks were destroyed in the worst-hit counties after the earthquake. The Mianyang CDC quickly launched its emergency response plan for major natural disasters within two hours after the earthquake, prepared and improved the technical guide for disease prevention after the earthquake and rapidly sent out quick response team. With the help of CDC aid teams across the country, Mianyang CDC successfully disinfected and buried 6,767,568 corpses, and disposed of millions of animal carcasses.They also disinfected and sterilised an area of 932.595 million square metres, eradicating 3,514,166 fly and mosquito breeding places and treating 5,254,228 cesspit times. By June 30, they had examined 11,092 water supply units and carried out disinfection of 319.7997 million cubic metres of drinking water. Besides, dynamic monitoring for water quality in the four worst-hit areas in Mianyang urban areas. They organised hygienic enforcement supervisors to develop food safety inspection, regulated catering services of the centralised settlements, destroyed spoiled and expired food and vegetables. The authorities prevented the masses from eating dead poultry or meat from carcasses to ensure no occurrence of food poisoning after the earthquake. Standard administration of the 170 settlements of the earthquake-afflicted people and 132 settlements of evacuated people was carried out in accordance with the rules of "Six Provisions and Four Reinforcements" and this would ensure no recurrence of public health events in the settlements. On Day 3 (May 15) after the earthquake, they established a real-time monitoring and report network of the epidemic situation after the earthquake and monitored diseases and symptoms of the people in the resettled region to ensure no occurrence of major epidemic cases. The monitoring results showed that the number of infectious disease cases was comparable to that in the previous years. Moreover, they carried out intensive vaccination with hepatitis A vaccine in children 41196 person times, stored 100,000 person oral cholera vaccine and monitoring for new sexually transmitted diseases. A total of 10.1265 million copies of publicity materials were organised printed and distributed. They developed large-scale health education and a massive patriotic health campaign by means of the media and organised the masses to engage in sanitation and hygiene as well as controlling flies, mosquitoes and rats in the temporary earthquake-proof places. Under the unified command of the Mianyang emergency response headquarters, the centers for health and epidemic control and prevention at various levels of disaster relief continued to dispose of carcasses and disinfect and bury corpses as well as monitor water quality, so as to ensure the secondary disasters could be prevented in advance.
Objective To report the anti-epidemic work for counterpart-supporting Longmen township, the epicenter of Lushan earthquake, by Mianyang health and epidemic prevention team from the first day to one month after the earthquake. Methods a) The following information was collected: work information and report forms of each counterpart-support small group, government work information, work information statistics and historical epidemic materials of health center, and epidemic prevention materials of Beichuan county. b) The epidemic prevention work of Longmen township from the first day to one month after earthquake were documentarily described, the expert group review was adopted to assess the disaster situation, epidemic situation and health needs, and the visual observation and trace method were used to monitor the vectors. Results a) The first team arrived in Ya’an city at the 19th hour after earthquake. The members of the team put forward the “City in-charge-of Township counterpart-support anti-epidemic mode” and they were approved to counterpart-support Longmen township. b) The second team involving 48 members assigned to the first team within 5 days after earthquake. Totally 224 local people were called up and they carried out a comprehensive work based on the “City in-charge-of Township counterpart-support anti-epidemic mode”: water quality and disease surveillance, disinfection and disinsectization at key sites, epidemic prevention in settlements, large-scale health education, and psychological intervention. c) As of 1 month after the earthquake, Mianyang health and epidemic prevention team had dispatched 20 vehicles and 122 people participated in the post-disaster epidemic prevention in Longmen township. The total disinfection area was 1 725 400 square meters, and disinsectization area was 1 162 500 square meters; 184 water samples were collected, and 7 717 family-times’ drinking water disinfection were guided; nearly 28 000 publicity materials were distributed; 8 636 people were visited and received for diagnosis; 33 cases with watery diarrhea and 16 cases with fever were found; 117 people were trained about mental health service, 3 mental health service stations were set up, and 1 152 people were helped with special population mental health services. Conclusion a) Mianyang health and epidemic prevention team combined the special requirements of epidemic prevention in Lushan earthquake with the proficient experiences and work modes of epidemic prevention in Mianyang as the extremely-severe stricken area in Wenchuan earthquake, and put forward the “City in-charge-of Township counterpart-support mode” which is implemented and verified in the anti-epidemic practice in epicenter of Longmen Township. b) Compared with the epidemic prevention in Qushan township of Beichuan county which is the epicenter of both Lushan and Wenchuan earthquakes: the following 8 aspects (including the “City in-charge-of Township counterpart-support” formed, the first anti-epidemic team entered into the village, full coverage of anti-epidemic team entered into the village, direct reporting network recovered, settlement’s regular administration started, water supply guaranteed, drinking water monitoring initiated, emergency vaccination initiated) were performed earlier in Lushan than Wenchuan, with 42 days, 2 days, 32 days, 4 days, 10 days, 6 days, 7 days, and 19 days in advance, respectively. c) The overall performance is faster, more reasonable, and more efficient. It can provide first-hand information for globally similar earthquake’s epidemic prevention, and also the decision-making and reference for both post-disaster reconstruction and construction of regional state disaster emergency response system.
