Objective:To study the perioral soft tissue characteristics of the subjects with ClassⅡDivisionⅠand various vertical pat-terns. Methods:Lateral cephalograms of 90 adults ( half men, half women) were divided into 3 groups based on GoGn-SN angle:low angle, normal angle and high angle(n=30). The perioral soft tissues were measured and compared for the determination of the vertical skeletal variables influencing soft tissue characteristics. Results: The subjects with low angle showed significantly smaller values than those with high angle for basic lower lip thickness and lower lip length(P<0. 05). Most measurements of soft tissue thickness were greater in men than in women in all groups, especially for basic upper lip thickness and upper lower lip thickness(P<0. 05). Conclu-sion:Orthodontists need to pay more attention to the differences of perioral soft tissue in the subjects with various vertical patters to ob-tain balance of the facial harmony in orthodontic treatment.

Non-small cell lung cancer (NSCLC) accounts for 85% of total cases of lung cancer, which has the highest incidence and mor-tality in China. Most patients with lung cancer present with advanced stage disease at the time of diagnosis. With the limited develop-ment of cytotoxic chemotherapy for NSCLC therapy, median overall survival in patients receiving platinum-based doublet chemothera-py has been less than one year in several trials. To date, anti-angiogenesis agents combined with chemotherapy, small molecule tyro-sine kinase inhibitors (TKI) and immune checkpoint inhibitors were commonly applied in NSCLC instead of purely chemotherapy, which makes a great breakthrough in NSCLC therapy. This review summarizes and discusses the application of anti-angiogenic therapy in ad-vanced NSCLC.

Helminth infections may trigger host innate and adaptive immune responses. Group 2 innate lymphoid cells (ILC2) are an important factor involved in type 2 immune responses, and produce a large number of T helper 2 cell (Th2) cytokines following stimulation by interleukin (IL)-25, IL-33 and thymic stromal lymphopoietin (TSLP), which play a critical role in parasite clearance and tissue repair. Following helminth infections, autocrine factors, mast cells, enteric nervous system and Th2 cells have been recently found to be involved in regulation of ILC2. Unraveling the role of ILC2 in immune response against helminth infections is of great value for basic research and drug development. This review summarizes the research progress on ILC2 and its role in helminth infections.

Background Bromadiolone is the second-generation anticoagulant rodenticide widely used all over the world. Exposure to bromadiolone in early life stage can lead to neurodevelopmental toxicity, but its toxic mechanism of neurodevelopment is not clear so far. Objective To investigate the developmental neurotoxicity and mechanism of bromadiolone to zebrafish embryos. Methods Zebrafish embryos were randomly divided into four groups: a solvent control group (dimethylsulphoxide) and three bromadiolone exposure groups (0.39, 0.78, and 1.18 mg·L−1). The exposure period was from 4 h to 120 h post-fertilization. The number of spontaneous movement per minute was recorded at 24 h post-treatment. The locomotor ability of zebrafish larvae and the activity of acetylcholinesterase (AChE) were tested at 120 h post-treatment. The relative expression levels of neurodevelopment-related genes (elavl3, gap43, mbp, and syn2a) were measured by fluorescence quantitative PCR. Results Compared with the control group, the number of spontaneous movement per minute at 24 h decreased significantly in the 1.18 mg·L−1 bromadiolone exposure group (P<0.05). Compared with the control group, the total distance travelled of the zebrafish larvae in the 0.78 and 1.18 mg·L−1 bromadiolone exposure groups decreased by 60% and 69% respectively (P<0.05, P<0.01), and the total movement time decreased by 34% and 65% respectively (P<0.05, P<0.01). The AChE activity in the 1.18 mg·L−1 bromadiolone exposure group increased by 36% when compared with the control group (P<0.05). The fluorescence quantitative PCR results showed that compared with the control group, the expression levels of neurodevelopment-related genes elavl3, syn2a, and mbp were significantly down-regulated by 66%, 69%, and 65% in the 1.18 mg·L−1 bromadiolone exposure group respectively (P<0.01), the expression level of gap43 was up-regulated by 56% in the 0.78 mg·L−1 bromadiolone exposure group (P<0.01) and down-regulated by 34% in the 1.18 mg·L−1 bromadiolone exposure group (P<0.05). Conclusion Bromadiolone exposure could inhibit spontaneous movement and locomotive behavior, down-regulate the expression levels of neurodevelopment-related genes, hinder the release of neurotransmitters, and result in neurodevelopmental toxicity in the early-staged zebrafish.
