Three groups were clinically observed in the present report. There were55 cases (104 eyes) in the first group for body acupuncture, of which 46 (83. 6%) cases were effec-tively treated; In the second group for auricular acupuncture, 34 (91. 6% ) cases (68 eyes) out of 37cases (74 eyes) were improved; There were 50 cases (100 eyes) in the third group for boyauricular-acupuncture, among which 48 (96. 0%) cases (96 eyes) were improved. The curative effects of thethird group were better than those of the other two groups.展开更多

The membrane lipid fluidity was obviously decreased from the membrane lipid fluorescence polarization. The membrane lipid fluidity of lympho- cyte, monocyte and neutrophilic granulocyte was dynamically observed. After culturing the cells for 1, 6, 24 and 72 h, it was found that all the membrane lipid fluidity of the infected cells was de- creased obviously with the longer the culturing time, the more obvious it. Compared with the normal control groups, there was a significant difference statistically (P<0. 05-0. 01). It was suggested that the decrease of the membrane lipid fluidity of normal bone marrow cell with infection of EHFV had correlation with the degree of virus invading and cellfunction injury.展开更多

The clinical courseamong these patients was similar to that described for patients with KoreanHemorrhagic Fever, Nephropathica Epidemica of Scandanavia and Hemor-rhagic Fever with Renal Syndrome of the U.S.S.R. The overall mortalitywas 11.2％. Sera obtaincd from some of these patients as well as frompatients admitted to the First Attached Hospital of Hubei Provincial Me-dical College were tested against an antigen associated with Korean He-morrhagic Fever and showed exceedingly high antibody titers. We concludethat EHF in Centfal China represents the same disease process as KoreanHemorrhagic Fever.展开更多

The natural nidi and epidemic areas of HFRS are distributed mainly in plain and hilly regions under 500 meters above the sea level; in plentiful-water zones and transitional zones; in temperate zone and subtropical zone of the eastern monsoon region; in the abundant-aluminum soil region and the sial soil region; in the eastern China damp forest region (agricultural districts and northeast forest districts); in the eastern Asia dampness-prefering animal geographic region. Apodemus agrarius and Rattus norvegicus are the thriving animal population, predominant species or common species as well as the main reservoir hosts and sources of infection in the natural nidi and epidemic areas of HFRS.展开更多

Objective: To identify the clinical, epidemiological and laboratory parameters associated with AHF cases found in patients hospitalized in STP. Methods: Descriptive and quantitative analysis of AHF cases hospitalized in STP in the period December 2021 to May 19, 2022 through the variables: demographic data;clinical data;laboratory data and clinical outcome. Results: Analyzed 18 of 22 AHF cases, 50% of them male, mean age 33.7 years, 85.7% residing in the 2 largest districts of the country, 66.7% rural workers, administrative near maritime areas, sailors and domestics. 66.7% were healthy individuals. ≥50% had a fever, asthenia/weakness, myalgia, headache, lethargy, nausea, vomiting, and diarrhea. 22.2% to 33.3% had retro-orbital pain, abdominal pain, decreased consciousness, dyspnea/hypoxia, and cough. In a smaller register (5.6% - 11.1%), exanthema, convulsion, arthralgia, low back pain, chills, and chest pain. Bleeding from the digestive tract was found in 72.2%, followed by vaginal (33.3%), urethral (27.8%), nasal (22.2%), and oral (16.7%). 50% had laboratory confirmation for dengue, and another 50% with suspected clinical diagnosis without laboratory confirmation of the etiologic agent. Despite hemorrhage, 66.7% of confirmed cases were hemodynamically non-severe, and 88.9% of suspected cases were severe. Coinfection with malaria is evidenced in 11.1% of cases. 72.2% recovered and 27.8% died (deaths in 55.5% of suspected cases). Case deaths were male (100%), resident foreigners (40%), tool store employees, sailors and students, healthy (80%), and residing in the largest district in the country (60%). All deaths were hospitalized in serious condition, 80% were hospitalized for hemorrhage and shock, with bleeding arising between day 4 - 5 of illness in 60% and hospitalization on day 5 of illness. 60% died within ≤24 hours of hospitalization. 80% died from shock and multi-organ dysfunction and 20% from respiratory failure. Deaths had thrombocytopenia (100%), renal dysfunction (100%) and significantly increased transaminases (100%), anemia (75%) and leukocytosis (66.7%). 20% had a radiological change of pulmonary infiltrates. Conclusion: Our data reveal the complexity of the pathogens causing AHF and suggest the possible presence of other human pathogens usually unknown in the Santomean geographical territory.展开更多
