Bronchial asthma(asthma for short) is a chronic inflammatory disease of the lung,which is involved with various cells and cytokines.Now,the related genes of asthma is not well-known yet.But research shows that there are related genes to airway hyperreactivity,IgE regulation and atopic reaction.These genes play an important role in asthma.In recent years,it is recognized that STAT family plays an important role in inflammatory and immunological diseases.In this article the role of STAT family played in asthma pathogenesis will be reviewed.

Objective: This study aimed to explore the feasibility of functional evaluation of the lateral pterygoid muscle (LPM) using diffusion tensor imaging (DTI) in patients with temporomandibular joint disorders (TMDs). Materials and Methods: A total of 119 patients with TMD (23 male and 96 female; mean age ± standard deviation, 41 ± 15 years; 58 bilateral and 61 unilateral involvements for a total of 177 joints) and 20 healthy volunteers (9 male and 11 female;40 ± 13 years; 40 joints) were included in this prospective study. Based on DTI of the jaw in the resting state, the diffusion parameters, apparent diffusion coefficient (ADC), fractional anisotropy (FA), λ1, λ2, and λ3 of the superior and inferior heads of the LPM (SHLPM and IHLPM) were measured. Patients with TMD with normal disc position (ND), anterior disc displacement with reduction (ADWR), and anterior disc displacement without reduction (ADWOR) were compared. Results: Patients with TMD overall, and ADWR and ADWOR subgroups had significantly higher ADC, λ1, λ2, and λ3 in both the SHLPM and IHLPM than those in volunteers (p < 0.05 for all), whereas the ND subgroup only had significantly higher ADC and λ1 (p < 0.001). Meanwhile, significant differences in FA in the SHLPM and IHLPM were found between volunteers and ADWOR (p = 0.014 and p = 0.037, respectively). Among the three TMD subgroups, except for λ3 and FA in the ADWR subgroup, ADWR and ADWOR subgroups had significantly higher ADC, λ1, λ2, and λ3 and lower FA than those in the ND group (p < 0.050). There was no significant difference in diffusion variables between ADWR and ADWOR. In ADWOR, the osteoarthritis group had significantly higher λ3 and lower FA values in the IHLPM than those in the non-osteoarthritis group. Conclusion DTI successfully detected functional changes in the LPM in patients with TMD. The unsynchronized diffusivity changes in the LPM in different subgroups of TMD signified the possibility of using diffusion parameters as indicators to identify the severity of LPM hyperfunction at various stages of TMD.

According to the principle of the types of hemangioma and the special structure of lip,infantile hemangioma is divided into 7 types as follows:superficial skin hemangioma,lip skin composite hemangioma,lip skin deep hemangioma,lip mucosa superficial hemangiomas,lip mucosa compound hemangioma,lip mucosa deep hemangioma and full-thickness lip hemangioma.Special structure and function of lip leading to tumor growth uniqueness and particularity of typing.Application of long-pulse laser combined with optimized pulsed light therapy is effective in the treatment of lip hemangioma.
