Objective: To investigate the histopathologic, immunohistochemical, molecular genetic characteristics of CIC-rearranged sarcoma (CRS) with rhabdoid features. Methods: The clinical and pathologic data of two cases of CRS diagnosed between 2019 and 2021 at the Department of Pathology, Jiangsu Province Hospital were analyzed. Immunohistochemical study and fluorescence in situ hybridization (FISH) were performed. The relevant literature was reviewed. Results: Both patients were female, one was 58 years old, with tumor located in left thigh; the other was 43 years old, with tumor located in left pelvic cavity. Microscopically, both tumors were composed of small to medium-sized round, oval cells, arranged in nodules or sheets. The tumor cells showed irregular nuclear outline, coarse chromatin with prominent nucleoli and brisk mitotic activity. Both cases showed rhabdoid phenotype with myxoid stromal changes. Immunohistochemically, both cases were positive for CD99 and c-myc. High WT1 reactivity was seen in classic area, with low reactivity in rhabdoid area. There was no INI1 lost in both cases. Both were negative for NKX2.2 and NKX3.1. By FISH both cases demonstrated convincing break-apart signals of CIC gene. One patient died of disease after 1 month, and the other died of disease after 3 months. Conclusions: CRS is a small round cell undifferentiated sarcoma of the bone and soft tissue defined by molecular genetic characteristics, and may show atypical morphologic and immunophenotypic characteristics such as rhabdoid features. A correct understanding of its rare morphologic and immunophenotypic characteristics, combined with molecular pathologic detection, is conducive to correct diagnosis.

Objective: To investigate the diagnostic value of rapid antigen test based on colloidal gold immunochromatographic assay for the detection of SARS-CoV-2 infection in symptomatic patients. Methods: From May 20 to June 5 2022, 76 hospitalized children and their 55 accompanying family members with confirmed SARS-CoV-2 infection in the COVID-19 isolation unit of the Children's Hospital of Fudan University (designated referral hospital for SARS-CoV-2 infection in Shanghai) enrolled. Their nasopharyngeal swab specimens were consecutively collected. The samples were tested for SARS-CoV-2 nucleic acid by real-time quantitative. SARS-CoV-2 antigen was tested by immunochromatography. The correlation between the antigen detection results and the change of the cycle threshold (Ct) values were evaluated, as well as the sensitivity and specificity of SARS-CoV-2 antigen detection at different periods after the onset of the disease. Kappa consistency test was conducted to investigate the consistency between the 2 diagnostic methods. Results: Of the enrolled SARS-CoV-2 symptomatic infections, 76 were children, including 41 males and 35 females, with an age of 5 (2, 9) years; 55 were accompanying families, including 8 males and 47 females, with an age of 38 (32, 41) years. All 478 samples were simultaneously tested for SARS-CoV-2 antigen and nucleic acid. In any period from disease onset to negative conversion of viral nucleic acid, the overall sensitivity of the rapid antigen test was 48.2% (119/247), the specificity was 98.3% (227/231), and antigen test and nucleic acid test showed moderate consistency (κ=0.46, P<0.05). The sensitivity of antigen test was 100% (82/82) when the Ct value was ≤25. And the sensitivity of antigen test was 8/10, 4/15 and 8.3% (3/36) when the Ct value was 26, 30 and 35, respectively. All antigen tests were negative when Ct value was >35. During the period of 1-2 days, 3-5 days, 6-7 days, 8-10 days and >10 days after onset, the sensitivity and specificity of SARS-CoV-2 antigen test were 5/8 and 5/5, 90.2% (37/41) and 5/5, 88.9% (24/27) and 2/5, 45.0% (36/80) and 94.1% (32/34), 18.7% (17/91) and 98.9% (183/185) respectively. The Ct values of nasopharyngeal swabs were<26 during 2 to 7 days after onset, 28.7±5.0 on day 8, 34.5±2.9 on day 13 and > 35 after 14 days, respectively . Conclusion: SARS-CoV-2 antigen test in the patients with SARS-CoV-2 infection shows acceptable sensitivity and specificity within 7 days after onset of disease, and the sensitivity was positively correlated with viral load and negatively correlated with onset time.

Objective:To explore the mechanism of Sishenwan， Baitouweng Tang， and Lianlitang in the treatment of ulcerative colitis （UC）， and compare their efficacies on UC in rats. Method:Ninety SD rats of SPF grade were randomly divided into blank group （distilled water， 2 mL·d^-1） and experimental group. The rats in the experimental groups were administered with 2，4，6-trinitrobenzene sulfonic acid （TNBS） by clysis to induce the UC model. Subsequently， the model rats were divided into a model group （distilled water， 2 mL·d^-1）， positive group ［sulfasalazine （SASP）， 0.4 g·kg^-1·d^-1］， Sishenwan group （1.76 g·kg^-1·d^-1）， a Baitouweng Tang group （1.40 g·kg^-1·d^-1）， and Lianlitang group （2.13 g·kg^-1·d^-1） according to the random number table. The rats in each group were dosed at 2 mL·d^-1 for 14 days. The pathological score for colonic mucosa was detected. Cytokines were detected by the cytokine chip. The enzyme-linked immunosorbent assay （ELISA） was used to detect the free triiodothyronine （FT₃）， glucagon-like peptide-1 （GLP-1）， and corticosterone （CORT） in plasma， and neurotensin （NT）， substance P （SP）， vasoactive intestinal peptide （VIP）， and somatostatin （SST） in colon tissues. Result:Compared with the normal group， the model group showed increased colon mass-length ratio and pathological score for colonic mucosa （P<0.01）， infiltration of massive lymphocytes， disordered or absent intestinal villi， elevated levels of cytokine-induced neutrophil chemoattractant-1/2α/β/3 （CINC-1/2α/β/3）， interleukin-1α （IL-1α）， interferon-inducible protein-10 （IP-10） and other factors in colon tissues （P<0.05）， dwindled CORT and GLP-1 levels in plasma （P<0.05）， and increased SP content in colon tissues （P<0.05）. Compared with the results in the model group， the mucosal injury in the colon of rats in each drug group was relieved. The levels of IL-1α， IP-10， lipopolysaccharide-inducible CXC chemokine （LIX）， and L-selectin of rats in the Lianlitang group and Sishenwan group were reduced （P<0.05）， and the CINC-3 and IL-17 levels were diminished in the Baitouweng Tang group （P<0.05）. The levels of CINC-1/3， IL-1α， and IP-10 were reduced in the SASP group （P<0.05）. The plasma FT₃ was up-regulated in the Lianlitang group， and the plasma GLP-1 levels were elevated in the three Chinese medicine groups （P<0.05）. The VIP content in colon tissues of the Sishenwan group and Baitouweng Tang group was down-regulated （P<0.05）， and the SST content in colon tissues of the SASP group was significantly up-regulated （P<0.01）. Conclusion:The intervention of Lianlitang and Sishenwan on UC was significant， and the underlying mechanism of action might be related to inflammation inhibition and immune balance by regulating the cytokine network. The efficacy of Lianlitang was predominant， followed by Sishenwan and Baitouweng Tang.

Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.
