It is important to prevent obesity in the prevention and control of hypertension and diabetes.

High expression of Fightless I (FLII) is associated to multiple tumors. Based on our previous study that FLII might be involved in the nuclear export, we assessed the possible interaction of FLII with the nuclear envelop associating proteins Importin β and Nup88. We first constructed GST-FLII, GST-LRR recombinant plasmids and transformed them into the Rosetta strain to produce GST-FLII, GST-LRR fusion protein. After purification of these proteins, GST-pull down, as well as co-immunoprecipitation, were used to test the interaction of FLII with Importin β and Nup88. FLII interacted with Importin β and Nup88, and FLII LRR domain is responsible for these interactions. Thus, FLII may play a role in nuclear export through interaction with Importin β and Nup88.

Thyroid-associated ophthalmopathy (TAO) is a common orbital disease in the adults, which leads to a series of ocular symptoms and signs, seriously affecting the visual function and life quality of patients.Grasping the disease progression accurately and evaluating the severity and activity of TAO objectively play a crucial role in improving the management and prognosis of TAO patients.Grading and staging methods of TAO have been constantly improved.In the descriptive evaluation of subjective symptoms and signs of TAO, four international grading and staging systems with similarities and different focuses, namely, NOSPECS, CAS, VISA and EUGOGO, have been proposed successively.In recent years, with the rapid development of science and technology, objective evaluation methods such as imaging technology and laboratory examination have played an important role in the grading and staging of TAO.Among them, the application of orbital CT and MRI has made a great breakthrough in quantitative analysis of the disease.Continuous summary of grading and staging methods of TAO can contribute to the guidance for improving diagnosis, treatment and prognosis of TAO.

Ocular choristoma is composed of ectopic tissues with normal structures. The pathogenesis still remains uncertain. Histopathologically, it is a dense connective tissue mixed with epidermal appendages, smooth muscle cells, mature adipose tissue, lacrimal glands, lymph nodes, skeletal muscle fibers, cartilage and bone. Because of its low incidence, most of published literature are case reports. The clinical manifestations are non-specific and we need to distinguish it from other ocular masses. The choice of surgical resection depends on the ocular symptoms, the effect on appearance, and the need for clinical confirmation. This paper reviews the epidemiology, etiology, pathogenesis, clinical manifestations, diagnosis, differential diagnosis and treatment of ocular choristoma.

Objective To explore the value of OSCE system combined with intelligent network in-formation platform in clinical skills assessment of obstetrics and gynecology. Methods 112 clinical medi-cal students who participated in the practice of gynecology and obstetrics in Second Military Medical Uni-versity in 2017 were randomly divided into the experimental group (network information OSCE) and the control group (traditional OSCE). The teaching results were evaluated by the questionnaire survey of teachers and students and the examination results as well. The statistical analysis was made with the Chi-square test and the t test respectively. Results According to the questionnaire survey of two skills assessment methods, the satisfaction index of the experimental group was higher than that of the control group in both teachers and students, and the difference was statistically significant (P<0.05). The total time of examination in the experimental group was lower than that of the control group, and the difference was statistically significant (P<0.05). The final total score and the results of case analysis and clinical operation examination of experi-mental group were all higher than those of the control group, but there was no statistical difference (P>0.05). Conclusion OSCE combined with the network information system has an unparalleled advantage in the assessment of the obstetrics and gynecology department. The system will promote clinical education of ob-stetrics and gynecology and the evaluation of the clinical ability of the medical students to a new height, which deserves popularization.

Objective To explore the diagnosis and treatment of fourth branchial cleft deformity.Methods The clinical data of a patient with bilateral fourth branchial cleft deformity in the neck were summarized,and the literature was reviewed.Results The patient was a 17-year-old male who had a painless lump in his neck for 10 years.During specialized examination,a lump approximately 4.0 cm × 3.0 cm in size could be palpated subcutaneously on the right side of the neck,with clear boundaries,a regular shape,a soft texture,and a wave-like sensation without obvious tender-ness.A fistula with a size of approximately 0.5 cm × 0.5 cm could be observed on the left side of the neck,and yellow clear liquid could be seen flowing out of the fistula.The surrounding skin was locally red and swollen,and the surface temperature of the skin was elevated.Computed tomography examination demonstrated a circular cystic low-density shadow approximately 4.4 cm × 3.4 cm in size in the right supraclavicular and anterior cervical regions.A flocculent isodense image could be observed in the middle;moreover,nodular calcification could be observed at the edge,and the surrounding fat spaces were blurred.The enhanced scan showed mild enhancement of the cyst wall but no obvious en-hancement of the contents.On the left side,a circular nodular shadow with a diameter of approximately 1.4 cm could be seen,with enhanced scanning and circular enhancement.The surrounding skin was thickened,and the subcutaneous fat gap was blurred.Multiple small lymph nodes could be observed on both sides of the neck,with the larger nodes having a short diameter of approximately 0.8 cm.The size and morphology of the thyroid gland were not significantly abnormal,and there was no obvious abnormal density shadow inside of the gland.Upon admission,the diagnosis was a fourth gill fissure cyst in the right neck and a fourth gill fissure fistula in the left neck.Under general anesthesia and intravenous anesthesia,right branchial cleft cyst resection and left branchial cleft fistula resection were performed.Postoperative pathological examination demonstrated a left branchial cleft fistula and a right branchial cleft cyst.The wound healed by first intention,and there was no recurrence after 6 months of follow-up.According to the literature,fourth branchial cleft deformity is a congenital developmental abnormality of the branchial apparatus,the incidence of which accounts for only 1％of all branchial cleft deformities;moreover,it often occurs on the left side.The anatomical position is often located in the cervical root and supraclavicular region,thus demonstrating cysts or sinuses adjacent to the thyroid gland.The di-agnosis should be confirmed by anatomical location,imaging examination or laryngoscopy combined with postoperative pathological results and should be differentiated from cervical masses such as thyroglossal duct cysts and lymph node metastasis.The main treatment methods include surgical procedures and endoscopic cauterization of the internal fistula.The prognosis is generally good,and there is a risk of recurrence;however,cancer rarely occurs.Conclusion Deformi-ty of the fourth branchial fissure is very rare;thus,it should be identified early to avoid excessive and ineffective surgi-cal drainage,reduce potential complications during resection and completely remove the lesion to prevent recurrence.

Objective To observe the influence of Huiyang Shengji Fang(Restoring Yang and Promoting Tissue Regeneration Decoction, HYSJF) and its decomposed formulas-Yiqi Wenyang Fang (Qi-supplementing and Yang-warming Decoction,YQWYF) and Huoxue Tongluo Fang(Blood-activating and collateral-freeing Decoction,HXTLF) on macrophage phenotype inversion,and discuss the mechanism of YQWYF and HXTLF in regulating macrophage phenotype inversion during the period of chronic skin ulcer. Methods THP-1 cells were stimulated and transformed into macrophages with PMA. After stimulated with LPS and INF-γ for 48 h, the macrophages were transformed into M1 macrophages. Lovastatin (10 μmol /L) was taken as control drug. The influence of YQWYF and HXTLF on activities of macrophages was observed by using CCK-8 method, and their influence on the phagocytosis of macrophages was detected by using neutral red uptake assay (NRU). The expressions of iNOS mRNA and Arg-1 mRNA were detected by using polymerase chain reaction (PCR) after M1 macrophages stimulated with lovastatin,YQWYF and HXTLF for 24 h. The levels of supernate TNF-α,IL-6,IL-12, IL-10 and VEGF were detected by using CBA method. The level of supernate TGF-β was detected by using ELISA. Results YQWYF,in dose of 4 mg/L (low-dose YQWYF group),0.8 mg/L (mid-dose YQWYF group) and 0.16 mg/L (high-dose YQWYF group), and HXTLF, in dose of 32 mg/L (low-dose HXTLF group),6.4 mg/L (mid-dose HXTLF group) and 1.28 mg/L (high-dose HXTLF group) had no influence on proliferation of macrophages but improved phagocytosis of NRU of macrophages. The expression of iNOS mRNA of M1 macrophages increased significantly after stimulated by LPS and INF-γ, and decreased significantly in lovastatin group, YQWYF group and HXTLF group compared with model group (P <0.01). The expression of Arg-1 mRNA of M2 macrophages decreased significantly after stimulated by LPS and INF-γ compared with normal group, was improved significantly in lovastatin group, YQWYF group and HXTLF group compared with model group (P <0. 01), and decreased significantly in YQWYF group and HXTLF group compared with lovastatin group. After M1 macrophages stimulated by above drugs for 24 h, the levels of TNF-α, IL-6 and IL-1 decreased significantly, and levels of VEGF and TGF-β increased significantly. The level of IL-10 increased significantly in high-dose YQWYF group (P<0.05),The levels of IL-10,VEGF and TGF-β had statistical difference in HXTLF group and high-dose YQWYF group compared with lovastatin group. Conclusion YQWYF and HXTLF can inhibit expression of iNOS mRNA of M1 macrophages and induce expression of Arg-1 mRNA of M2 macrophages, and can inhibit the secretion of M1 macrophage cytokine and improve secretion of M2 macrophage cytokine.
