Hereditary angioedema(HAE)is a rare autosomal dominant disorder characterized by recur-rent,unpredictable episodes of skin and mucosal edema,which may affect the face,extremities,respiratory tract,gastrointestinal tract,and genitals,with a global prevalence of approximately 1 in 50 000.This case re-port presents a young female patient with a history of recurrent abdominal pain and multisite edema.During an acute episode,laboratory tests revealed decreased complement C4 levels along with reduced concentration and function of C1 esterase inhibitor.Computed tomography(CT)demonstrated bowel wall edema and pelvic effu-sion.Previously undiagnosed,the patient was admitted for this acute attack and was ultimately diagnosed with HAE following a multidisciplinary treatment(MDT)team discussion at our hospital.The rapid diagnosis and treatment of this case highlight the critical role of MDT in the management of complex and rare diseases.

The fall armyworm (FAW), Spodoptera frugiperda, is a destructive pest native to America and has recently become an invasive insect pest in China. Because of its rapid spread and great risks in China, understanding of FAW genetic background and pesticide resistance is urgent and essential to develop effective management strategies. Here, we assembled a chromosome-level genome of a male FAW (SFynMstLFR) and compared re-sequencing results of the populations from America, Africa, and China. Strain identification of 163 individuals collected from America, Africa and China showed that both C and R strains were found in the American populations, while only C strain was found in the Chinese and African populations. Moreover, population genomics analysis showed that populations from Africa and China have close relationship with significantly genetic differentiation from American populations. Taken together, FAWs invaded into China were most likely originated from Africa. Comparative genomics analysis displayed that the cytochrome p450 gene family is extremely expanded to 425 members in FAW, of which 283 genes are specific to FAW. Treatments of Chinese populations with twenty-three pesticides showed the variant patterns of transcriptome profiles, and several detoxification genes such as AOX, UGT and GST specially responded to the pesticides. These findings will be useful in developing effective strategies for management of FAW in China and other invaded areas.

Tumor stem cells are responsible for metastasis and relapse of cancer.Transforming growth factor-β1 (TGF-β1) plays an important role in the proliferation and differentiation of tumor stem cells.In many cancers such as breast carcinoma,hepatocellular carcinoma,pancreatic carcinoma,lung carcinoma,glioma and gallbladder carcinoma,the epithelial-mesenchymal transition (EMT) induced by TGF-β1 can inhibit proliferation of cancer cell,enrich tumor stem cells and increase invasive capability and drug resistance of cancer.
