Objective To summarize and analyze the epidemiological and clinical characteristics of COVID-19 Omicron variant cases in makeshift hospital, and the influence of age, sex and vaccination status on the disease duration, so as to provide reference for the prevention and control of the COVID-19 epidemic. Methods The epidemiological and clinical characteristics of COVID-19 cases admitted to makeshift hospital of National Convention and Exhibition Center (Shanghai) from April 9 to May 31, 2022 were retrospectively described and analyzed, and further cohort analysis was conducted to
determine the influence of age, sex and vaccination status on the disease duration of COVID-19 cases in the author's branch hospital. Results Among the 174 466 COVID-19 cases in makeshift hospital, most of them were male, accounting for 59.38%. The infected cases were mainly young and middle-aged people aged 18-59 years old, accounting for 83.50%, followed by 12.30% of the elderly group over 60 years old; the average hospital stay was 7.40 days; the proportion of patients with fever was less than 27.79%; 15.37% (26 817/174 466) of the patients complicated with underlying diseases, and the top three were hypertension, diabetes and coronary heart disease. The proportion of people who received COVID-19 vaccine accounted for 79.56% (13 799/17 956), of which the highest proportion of three doses was 44.09%. The disease duration of 17 956 COVID-19 cases in the author's branch of makeshift hospital was 10.18 (7.34, 13.05) days. The disease duration in the elderly group
was the longest with 11.34 (8.35, 14.37) days, followed by 11.17 (9.07, 14.33) days in the preschool group, 10.37 (8.14, 13.34)· days in the middle-aged group, 10.07 (7.37, 12.37) days in the school-age group, and 9.34 (7.05, 12.16) days in the young group. There was significant difference in the overall distribution of disease duration among the five groups (H=550.479 P<0.01). The disease duration in each age group basically showed a V-shaped distribution. The disease duration was 10.27 (7.34,
12.57) days in males and 10.10 (7.25, 13.09) days in females, and there was no significant difference (Z=-1.505 P>0.05). The disease duration of vaccinated patients was 10.24 (7.35, 13.05) days, and that of unvaccinated patients was 9.47 (7.09, 12.47) days. There was significant difference between the two groups (Z=-4.338 P<0.01). Conclusions COVID-19 Omicron variant cases have a high proportion of males, mainly young and middle-aged, and the proportion of fever patients is less than 30%.
The disease duration is significantly lower than that of the original strain in Wuhan, and shows "V" distribution with each age group. Sex had no effect on the disease duration. COVID-19 vaccination did not have a clinical effect on the disease duration.

Aim To develop the in vitro and in vivo models induced by shrimp tropomyosin( ST) and mono-clonal tropomyosin-specific murine IgE antibody ( anti-ST-IgE mAb) . Methods ST was purified from Metap-enaeusensis by an isoelectric precipitation method. The anti-ST-IgE mAb was obtained from hybridomas. After RBL-2 H3 cells were sensitized with anti-ST-IgE mAb and challenged with ST,β-hexosaminidase release was determined. Passive systemic anaphylaxis ( PSA ) was induced in mice and the rectal temperature was recor-ded after ST challenge within 30 min by a thermal probe. Results A significant increase ofβ-hexosamin-idase was observed in sensitized cells after ST chal-lenge. The average temperature drop after ST challenge was 1. 44℃ in PSA mice within 30 min. Conclusion The in vitro and in vivo models induced by ST and anti-ST-IgE mAb are established as an improvement of pres-ent models of type Ⅰ allergy.

Objective:To study the relationship between the expression of carnitine palmitoyltransferase 1α (CPT1α) and progression of renal interstitial fibrosis and chronic kidney disease (CKD), and to evaluate the value of CPT1α as a biomarker in pathological diagnosis of renal interstitial fibrosis and CKD.Methods:As a retrospective cohort study, information of CKD patients dignosed with tubulointerstitial fibrosis by renal biopsy and receiving follow-up from March 1, 2010 to July 30, 2017 in the Second Affiliated Hospital of Nanjing Medical University were collected. Renal tissues were stained by immunohistochemistry to detect the expression of CPT1α protein and then divided into three groups according to the quartile of proportion of CPT1α positive staining cells, including group Q1(>67.89%), group Q2(49.84%-67.89%) and group Q3(<49.84%). The degree of renal interstitial fibrosis was measured by Masson staining and lipid deposition was represented by Bodipy staining. Messenger RNA of CPT1α and collagen as well as other extracellular matrix genes were detected by real time-PCR. Relationships between proportion of CPT1α positive staining cells and renal interstitial fibrosis and renal function were analyzed by linear regression analysis. The relationship between CPT1α positive cell number ratio and renal function progression was measured by Pearson correlation analysis and generalized linear model. The effect of lipid-lowering medicine on renal function of CKD patients was analyzed by paired comparative analysis.Results:Ninety patients with CKD were included in this study. Renal interstitial fibrosis and lipid droplets deposition area increased in Q2/Q3 group compared with Q1 group by Masson and Bodipy staining (all P<0.05). Messenger RNA level of extracellular matrix-related proteins increased in Q2/Q3 group by real time-PCR than those of Q1 group (all P<0.05). Linear regression analysis showed that fibrosis area was negatively correlated with the proportion of CPT1α positive staining cells ( r=-0.309, P<0.01). The baseline expression of CPT1α in renal issues was negatively related with serum creatinine (Scr) ( r=-2.801, P<0.001), positively related with estimated glomerular filtration rate (eGFR) ( r=1.240, P<0.001). After a medium follow-up of 3.47 years, CPT1α positive cell number ratio was positively correlated with eGFR change rate by Pearson analysis ( r=0.220, P=0.038). Paired stratified analysis showed that taking lipid-lowering medicines attenuated the decrease of eGFR in Q2 group and Q3 group but not in Q1 group (both P<0.05). Conclusions:The decline of CPT1α in renal tissues of CKD patients is associated with the increase of Scr, the decrease of eGFR and renal interstitial fibrosis. CPT1α is a promising molecular marker to evaluate the degree of renal fibrosis and the progression of CKD.

Objective:To develop murine models of Th2 response induced by shrimp tropomyosin (ST). Methods:Mice were sensitized with ST for 6 weeks. The serum antigen-special IgE (sIgE),total IgE and sIgG level,Th1/Th2 cytokines production were measured by ELISA. The basophil activation in mice was measured by flow cytometry. Results:The intraperitoneal sensitization with ST for 6 weeks induced significant increase of serum sIgE,total IgE and sIgG (sIgG1,sIgG2a and sIgG2b) level in mice. Th2 cell response was induced and cytokines (IL-4,IL-5,IL-10 and IL-13) production increased in splenocytes stimulated by ST,while Th1 cytokine (IFN-γ) production decreased. As the markers of basophil activation,CD200R and CD41 expression also increased in response to ST. Conclusion:The Th2 response is dominant in ST-induced anaphylaxis in mice.

Objective To investigate the effects of inhibitor of growth 5 (ING5) gene on the proliferation, apoptosis, migration and cell cycle of human breast cancer Bcap-37 cells.Methods The eukaryotic ING5-expressing plasmid and GFP-empty plasmid were steadily transfected in Bcap-37 cells, the expression of green fluorescent protein was measured with fluorescence microscopy, and the high expression of ING5 was measured by real time-PCR. Bcap-37-ING5 cells served as the experimental group, Bcap-37-GFP cells as the mock group and Bcap-37 as the control group. The effects of ING5 on the proliferation were detected by MTT, the cell cycle and apoptosis were detected by Flow cytometry, and the cell migration was detected by cell wound scratch assay and Transwell experiment.Results Bcap-37 cell lines steadily expressing ING5 protein with GFP-tag were acquired by stable transfection. ING5 over-expression inhibited the proliferation and led to G2 arrest of Bcap-37 cells, increased cells apoptosis and decreased the cell migration ability (P<0.05).Conclusion ING5 over-expression may have reverse effect for malignant phenotype of breast cancer cells, and may be employed to indicate the biomarker of prognosis of breast cancer patients and regarded as a target of gene therapy.
