Microporous titanium dioxide thin films have been grown on titanium plates by the micro-plasma oxidation method with different current densities (4, 6, 10 and 14 A/dm2). X-ray diffraction, scanning electronic microscopy and UV-Vis spectrophotometry were used to characterize the films. It is found that the films grown are microporous and consist of crystalline titanium dioxide. The micropore size and the content of anatase and rutile TiO2 phase increase with the applied voltage. The relatively higher degradation efficiency for rhodamine B is obtained in the film produced with a current density of 10 A/dm2.

The incidence of gastrointestinal (GI) tumors is increasing year by year, and its pathogenesis is closely related to the intestinal flora. At present, the use of antibiotics is very common in the clinic. And cancer patients with low immunity are vulnerable to all sorts of infections, such as respiratory tract infections and urinary tract infections. Moreover, cancer patients easily run into fever and neutropenia induced by myelosuppression. Therefore, antibiotics are used extensively and even overused in many conditions. However, because of the special anatomical location of the gastrointestinal tract, the antibiotic usage will bring changes to the intestinal flora. Besides, with the expanding popularity of immunotherapy, various factors affecting the efficacy of immune checkpoint inhibitors (ICIs) have been extensively explored, including cancer-associated inflammation and the local and systemic factors that lead to immunosuppression. Some biomarkers for ICIs, including the expression of PD-L1, tumor mutation load, and microbiota, also have been investigated, and many studies have confirmed that gut microbiota can affect the efficacy of immunotherapy. But further studies on the influence of antibiotics directly on immunotherapy are rare. In this review, we discuss the relationship between GI tumors and antibiotics, the current status of immunotherapy in GI tumors, and the influence of antibiotics on immunotherapy.

Objective: To determine the clinical, imaging, and histological features, and surgical resection modalities and outcomes of adult sacrococcygeal teratoma (SCT). Methods: Adult patients with histopathologically diagnosed SCT were enrol ed in our hospital between August 2010 and August 2018. Each patient's characteristics and clinical information were reviewed. Results: There were 8 patients in the study (2 males, 6 females) with a median age of 34 years (range, 18-67 years). The time to clinical symptoms was 14 d to 35 years, with a median time of 4 years. Six patients presented with symptoms of sacrococcygeal pain, and four with signs of sacrococcygeal mass and ulceration in the sacrococcygeal region. Six patients were evaluated using a combination of computed tomography (CT) and magnetic resonance imaging (MRI). Al patients showed a presacral tumor with heterogeneous intensity on CT images. Al patients underwent surgical treatment, including 6 parasacral, 1 transabdominal, and 1 combined anterior-posterior surgery cases. Seven patients were histopathological y diagnosed with benign mature SCT, and have shown no recurrence. One patient had malignant SCT, with recurrence at 84 months after surgery. After a second surgery, the patient had no recurrence within 6 months fol ow-up after re-resection. Conclusions: Our retrospective study demon-strated: (1) adult SCT is difficult to diagnose because of a lack of typical clinical symptoms and signs;(2) a combination of CT and MRI examination is beneficial for preoperative diagnosis;(3) the choice of surgical approach and surgical resection modality depends on the size, location, and components of the tumor, which can be defined from preoper-ative CT and MRI evaluation;(4) most adult SCTs are benign;the surgical outcome for the malignant SCT patient was good after complete resection. Even for the patient with recurrent malignant SCT, the surgical outcome was good after re-resection.

民族自治地方服务型政府建设是民族区域自治制度功能的重要体现,要求实现民族区域自治执行主体角色的转换,转变民族自治地方政府职能,提升民族自治地方政府能力,转变民族自治地方政府管理模式,建设"规制—服务型"地方政府。制度供给和财力保障是民族自治地方服务型政府建设的两个关键变量。在现阶段财力有限的情况下,遵循基本公共服务大体均等原则的指导,建设"项目导向型"政府,实行基本公共物品的项目式供给,是民族自治地方服务型政府建设的可行途径。
