Maintenance hemodialysis patients face great risk and challenges in the current coronavirus disease 2019 (COVID-19) epidemic, and adequate and reasonable nutrition is an important weapon in the prevention and treatment of COVID-19. Therefore, the Chinese Society of Parenteral and Enteral Nutrition proposed Dietary Expert Advice on Prevention and Treatment of COVID-19 in Hemodialysis Patients for hemodialysis patients. In this paper, the nine pieces of advice on hemodialysis patients’ staple food, intake of high-quality protein, vegetables and fruits, food types and combinations, prevention of virus transmission, fluid intake, nutritional supplements, regular rest and adequate sleep, as well as supplement of anti-inflammatory and antioxidant preparations are interpreted in detail.
Since January 2020, due to the epidemic of coronavirus disease 2019, all universities in China have postponed their studies or even suspend their studies. In response to the teaching policy of “suspending class, but keeping teaching and learning” , college teachers have rapidly changed into online teaching mode. However, how to ensure the quality and effect of online teaching still needs further exploration. Through analyzing the course characteristics of medical imaging diagnostics and students’ learning situations, this study discusses how to design detailed online teaching projects and improve the teaching quality and how to select online software suitable for the course. A questionnaire survey was conducted to evaluate the effect of online teaching during the spring course in 2020, selecting a total of 297 clinical and other undergraduate students of grade 2017 from West China School of Medicine of Sichuan University. The results showed that the detailed online teaching programs including “video learning” “distance teaching” “periodic examination” “weakness tutorial” were helpful to the learning process agreed by the majority of students. During the epidemic period, online teaching method can help students master the content of medical imaging diagnosis. In the era of Internet, the “online+offline” teaching mode is expected to be popularized in the future.
ObjectiveTo evaluate the role of CD3+CD4+T cells in patients with nosocomial infection in ICU.
MethodsOne-hundred and eleven patients who admitted in ICU and in respiratory department from March to December in 2014 were recruited in the study.There were 33 patients with community-acquired pneumonia (CAP group), 31 patients without nosocomial infection (NNI group), and 47 patients with hospital-acquired pneumonia (HAP group).The counts of T cells, B cells, CD3+CD4+ T cells, CD3+CD8+ T cells, and NK cells were compared among three groups.
ResultsThe comparison among the groups had no statistical significance in sex and age(P > 0.05).The three groups had statistical significance in APACHEⅡscore, CD3+CD4+T cells, T cells and B cells, but had no statistical significance in CD3+CD8+T cells, CD3+CD4+/CD3+CD8+ T cells, NK cells, white blood cells, neutrophils, procalcitonin or C reactive protein.CD3+CD4+T cells of HAP group were less than other two groups.The area under the ROC curve (AUC) was 0.660, with a threshold of 29.96%, a sensitivity of 93.8%, and a specificity of 40.4%.
ConclusionCD3+CD4+ T cell is an independent predictor for nosocomial infection.

Methods The pulmonary X-ray and CT findings of 3 patients who were confirmed by laboratory results and epidemiology with infection of influenza virus A/H1N1 were retrospectively analyzed between March 2009 to November 2009. Results Both sides of the lung field showed many small cloudy infiltration in chest X-ray and CT film. The lesions of the lung were mostly near the pleural. They were often found in basal segment. Pleural effusion may be observed. Radiology dynamic changes showed the diffusion of the lesions of the lung was quick in a short time, and scattered and disappeared quickly after rational use of drugs. The lesions vanished later than clinical disappearance. The lesions of the lung may appear fibrosis at the period of the end. Conclusion Some radiographic characteristics exist in the pneumonia of patients with influenza virus A/H1N1 infection. It will be helpful for early diagnosis when getting familiar with its X-ray and CT manifestations, but the final diagnosis depends on the laboratory results and epidemiological history.
ObjectiveTo explore the clinical value of the soluble urokinase type plasminogen activator receptor (suPAR) level in bronchoalveolar lavage fluid (BALF) for evaluateting the disease severity and prognosis of severe community-acquired pneumonia (SCAP).
MethodsEighty-four patients with SCAP were recruited as a SCAP group from the respiratory department, ICU and RICU between April 2014 and April 2016. According to their organ dysfunction, the SCAP patients were subdivided into a MODS group and a non-MODS group. Depending on the treatment response on the 7th day of treatment, they were subdivided into an effective group and an ineffective group. According to the survival condition within 28 days, they were subdivided into a survival group and a death group. Meanwhile, 50 cases with non-severe common community acquired pneumonia were recruited as a control group. On the admission day, all cases were evaluated by PSI score and APACHE Ⅱscore. The serum suPAR level were detected by ELISA on the 1st day in hospital. The suPAR and procalcitonin (PCT) levels in the patient's BALF and serum were detected on the 1st, 3rd, 7th day, discharge or death day. The symptoms and signs, biochemical and pulmonary imaging changes were also observed.
ResultsThere were no differences in the sex, age, body weight, duration of pneumonia, or complicated diseases such as hypertension, coronary heart disease and cerebral vascular diseases between the SCAP group and the control group (all P > 0.05). The suPAR levels in serum and BALF of the SCAP group were higher than those of the control group with significant differences (all P < 0.05). The suPAR level in BALF was obviously higher than that in serum in the SCAP group with significant difference (P < 0.05), and slightly higher than that in serum in the control group with no significant difference (P > 0.05). The level of suPAR in BALF of the MODS group was significantly higher than that in the non-MODS group with significant difference (P < 0.05), but there was no significant difference in the PCT level between the two groups (P > 0.05). The suPAR level in the ineffective treatment group was significantly higher than that in the effective treatment group on the 7th day in hospital with significant difference (P < 0.05). The suPAR levels in BALF of the death group were higher than those in the survival group at each time point after admittion with significant difference (all P < 0.05), and the PCT levels had no significant difference between the two groups within 1 week of each time point (all P > 0.05). The suPAR level in BALF of the SCAP group was positively correlated with APACHEⅡ score and PSI score (r=0.578, P=0.0085; r=0.565, P=0.0071), and plasma PCT level was weakly correlated with the APACHEⅡ score and PSI score (r1=-0.0137, r2=-0.0152).
ConclusionThe SuPAR level in BALF of patients with SCAP is closely related to the severity and prognosis, and can be used as an index to assess the severity and prognosis.
ObjectiveTo investigate the anxious level of people with epilepsy (PWE) during the outbreak of 2019 Novel Coronavirus Diseases (COVID-19) and explore the reasons of anxiety.MethodsAn internet questionnaire survey were conducted on the anxiety state of PWE and health controls (HC) aged 18 to 45 years old between Feb 9, 2020 and Feb 17, 2020. The questionnaire included demographic information, general status and the State-Trait Anxiety Inventory (STAI).ResultsIn all, 148 PWE and 300 HC were included in this study. The total SAI score (46.72±9.98 vs. 41.77±10.20, P<0.001) and the total TAI score (44.18±8.88 vs. 31.27±17.44, P<0.001) were significantly higher in PWE than in HC. PWE concerned most (69.9%) about the difficulty of obtaining antiepileptic drugs (AEDs) while HC concerned most about the lack of face masks (73.3%).ConclusionHigh anxious level in PWE during the outbreak of COVID is probably due to the difficulty of obtaining AEDs. Thus, the society should strengthen the solution of the problem of purchasing AEDs and conduct timely psychological counseling.
ObjectiveTo analyze the clinical characteristics and epidemiological characteristics of patients with coronavirus disease 2019 treated early in Jiangxi province.MethodsFour-night patients with coronavirus disease 2019 treated in this hospital from January 21st to 27th, 2020 were included in this study. The epidemiological and clinical data of patients after admission were collected, and laboratory tests such as blood routine, urine routine, stool routine, liver and kidney function, electrolytes, myocardial enzymes, erythrocyte sedimentation (ESR), C-reactive protein (CRP), calcitonin, coagulation, T cell subset and Chest CT were reviewed. The clinical results of common and severe/critically ill patients were compared.ResultsOf the 49 patients, 40 were common and 9 were severe/critical. Fourty-six patients had a clear history of contact with Wuhan or other areas of Hubei. The sex ratio was 2.06∶1, and the average age was 42.9 years. The symptoms were mainly fever (78.7%), cough (38.8%), and fatigue (18.4%). 28.6% (14 cases) of patients had hypertension and diabetes. Serum lymphocyte count and calcium concentration of the patients were decreased, but lactate dehydrogenase, ESR, CRP and serum amyloid A were increased in these patients. T lymphocyte subsets (CD3+, CD4+, CD8+) decreased significantly in these patients. Forty-seven patients (95.9%) had single or scattered patchy ground glass density shadows on the chest CT. Compared with common patients, the patients with severe/critical patients were older (P=0.023), hospitalized later (P=0.002), and had higher comorbidities (P=0.017). ESR (P=0.001), CRP (P=0.010) and the serum amyloid A (P=0.040) increased significantly, while CD3+ (P<0.001), CD4+ (P=0.012), CD8+ (P=0.006) decreased significantly in severe/critical patients.ConclusionsThe patients with coronavirus disease 2019 in Jiangxi province are commonly imported from Wuhan. Severe/critical patients are older, hospitalized later, and have more medical complications and more severe systemic inflammatory reactions than common patients.
ObjectiveTo analyze the relationship between preoperative pulmonary function indexes and postoperative pneumonia (POP) in patients undergoing upper gastrointestinal surgery.MethodsThe clinical data of 303 patients who underwent lung function examination and upper gastrointestinal surgery in West China Hospital, Sichuan University from September 2020 to January 2021 were prospectively collected and analyzed. There were 217 males and 86 females, with an average age of 61.61±10.42 years. Pulmonary function was evaluated from four aspects including ventilatory function, pulmonary volume, diffusion function and airway resistance. Relevant pulmonary function indicators were displayed as the percentage of actual measured value to predicted value (%pred). The outcome index was pneumonia within 30 days after the surgery. Logistic regression was used to analyze the relationship between preoperative pulmonary function indicators and POP.ResultsA total of 196 patients with gastric cancer and 107 patients with esophageal cancer were included, and the incidence of POP in patients undergoing upper gastrointestinal surgery was 26.7% (81/303). Patients with preoperative low peak expiratory flow (PEF%pred) had a 3.094 times higher risk of developing POP than those with normal PEF%pred [OR=3.094, 95%CI (1.362, 7.032), P=0.007]. The incidence of POP had no correlation with the other preoperative indicators.ConclusionPreoperative PEF%pred may be an important indicator for predicting the occurrence of POP in patients undergoing upper gastrointestinal surgery.
