Analysis of inflammatory parameters and disease severity for 88 hospitalized COVID-19 patients in Wuhan, China.

Background and aim: The outbreak of coronavirus disease 2019 (COVID-19) is quickly turning into a pandemic. We aimed to further clarify the clinical characteristics and the relationship between these features and disease severity. Methods: In this retrospective single-center study, demographic, clinical and laboratory data were collected and analyzed among moderate, severe and critically ill group patients. Results: 88 hospitalization patients confirmed COVID-19 were enrolled in this study. The average age of the patients was 57.11 years (SD, ±15.39). Of these 88 patients, the median body mass index (BMI) was 24.03 (IQR, 21.64-26.61; range 15.05-32.39), the median duration from disease onset to hospital admission were 11 days (IQR, 6.50-14.50). 46.59% patients had one or more comorbidities, with hypertension being the most common (26.14%), followed by diabetes mellitus (12.50%) and coronary atherosclerotic heart disease (CAD) (7.95%). Common symptoms at onset of disease were fever (71.59%), cough (59.09%), dyspnea (38.64%) and fatigue (29.55%). 88 patients were divided into moderate (47 [53.41%]), severe (32 [36.36%]) and critically ill (9 [10.23%]) groups. Compared with severe and moderate patients, lymphocytopenia occurred in 85.71% critically ill patients, and serum IL-2R, IL-6, IL-8, TNF-α, LDH, and cTnI were also increased in 71.42%, 83.33%, 57.14%, 71.43%, 100% and 42.86% in critically ill patients. Through our analysis, the age, comorbidities, lymphocyte count, eosinophil count, ferritin, CRP, LDH, PT and inflammatory cytokines were statistically significant along with the disease severity. Conclusion: We found some clinical characteristic and inflammatory cytokines could reveal the severity of COVID-19 during the outbreak phage. Our research could assist the clinicians recognize severe and critically ill patients timely and focus on the expectant treatment for each patient.

[Microbial Community Diversity Analysis During Composting of Lincomycin Mycelia Dreg with Manure].

Aerobic composting experiments were conducted using lincomycin mycelia wastes (dreg) and manure (T), using sewage sludge with manure as a control (CK). High performance liquid phase methods and high throughput sequencing were used to determine the concentration of lincomycin residue and to characterize the microbial community. The results showed that lincomycin was reduced significantly, with the concentration decreasing from 1800 mg·kg-1 to 483 mg·kg-1, accounting for 73% degradation. In addition, the bacterial community abundance and diversity indices were all lower than that of sludge-manure at the mesophilic and thermophilic phases, because of the high concentration of lincomycin residue in lincomycin mycelia dreg. By contrast, the fungal community abundance and diversity indices showed the reverse, due to the high content of organic matter and nitrogen in lincomycin mycelia dreg. Therefore, the microbial communities were greatly different between T and CK treatment with the domain genera of Paucisalibacillus, Cerasibacillus, Bacillus, Virgibacillus, Ureibacillus, Paenibacillus, and Sinibacillus in T compost and Truepera, Actinomadura, Pseudosphingobacterium, Pseudomonas, Luteimonas and Ureibacillus in CK compost. However, as the composting continued to a mature phase, most of the lincomycin was reduced, and the differences between the two microbial communities gradually decreased. This showed that composting could make lincomycin mycelia dreg harmless and could be used to turn it into a resource.

[Stereotactic multi-target operation for patients with affective disorder].

OBJECTIVE: To explore the efficacy and complication of bilateral multi-target radiofrequency lesion operation in patients with affective disorder. METHODS: One hundred and eighty-two cases with affective disorder were treated with unstaged bilateral multi-target radiofrequency thermocoagulation. The efficacy was evaluated with the method established in 1990 by the National Psychosurgery Cooperative Group. RESULTS: After 2 weeks of operation, 86 cases with remarkable improvements, 81 cases with improvements, 15 case with no improvements, no case with progression, total efficient ratio was 91.76%. With 6-54 months of follow-up to all of 166 cases, 38 cases with recovery, 59 cases with remarkable improvements, 52 cases with improvements, 17 cases with no improvements, no case with progression, total efficient ratio was 89.76%. Except for early temporal complication of stereotaxic operation, the long-term complication ratio was less than 1%. CONCLUSION: CT-guided bilateral multi-target operation is prominent in treatment of affective disorder with high efficacy and safety.
