Cytological examination of the pericardial fluid confirmed the diagnosis of adenocarcinoma, and by extension, cardiac metastasis of the ascending colon cancer. Anticancer agents were recommended, but the patient opted for palliative treatment. CONCLUSIONS We report a rare case of ascending colon cancer with pericardial metastasis. The advancements in chemotherapy have made the prognosis of colorectal cancer more favorable. The prevalence of pericardial metastasis is expected to increase as well. As such, it is necessary to discuss similar case encounters and establish appropriate treatment.BACKGROUND Periodontal ligament stem cells (PDLSCs) are promising seed cells for bone tissue engineering and periodontal regeneration applications. However, the mechanism underlying the osteogenic differentiation process remains largely unknown. Previous reports showed that prolactin-induced protein (PIP) was upregulated after PDLSCs osteogenic induction. However, few studies have reported on the function of PIP in osteogenic differentiation. The purpose of the present study was to investigate the effect of PIP on osteogenic differentiation of PDLSCs. MATERIAL AND METHODS The expression pattern of PIP during PDLSCs osteogenic differentiation was detected and the effect of each component in the osteogenic induction medium on PIP was also tested by qRT-PCR. Then, the PIP knockdown cells were established using lentivirus. The knockdown efficiency was measured and the proliferation, apoptosis, and osteogenic differentiation ability were examined to determine the functional role of PIP on PDLSCs. RESULTS QRT-PCR showed that PIP was sustainedly upregulated during the osteogenic induction process and the phenomenon was mainly caused by the stimulation of dexamethasone in the induction medium. CCK-8 and flow cytometer showed that knocking down PIP had no influence on proliferation and apoptosis of PDLSCs. ALP staining and activity, Alizarin Red staining, and western blot analysis demonstrated PIP knockdown enhanced the osteogenic differentiation and mineralization of PDLSCs. CONCLUSIONS PIP was upregulated after osteogenic induction; however, PIP knockdown promoted PDLSCs osteogenic differentiation. PIP might be a by-product of osteogenic induction, and downregulating of PIP might be a new target in bone tissue engineering applications.BACKGROUND Jejunoileal neuroendocrine tumors (JI-NETs) are rare tumors that can be associated with mesenteric fibrosis. This case report is of an incidental finding of a JI-NET in a patient who was previously misdiagnosed with sclerosing mesenteritis. CASE REPORT A 42-year-old man was admitted to our institution with diffuse abdominal pain and clinical and radiographic signs of bowel obstruction. He had a previous diagnosis of sclerosing mesenteritis, which had been histologically diagnosed after an exploratory laparoscopy performed in 2009 for recurrent acute abdominal pain. He was also annually monitored through computed tomography scans for an incidentally discovered, gradually enlarging mesenteric mass for which a "wait and watch" management approach was adopted. After a period of fasting and observation, the patient underwent an urgent exploratory laparotomy because of his worsening condition. Intraoperatively, an ileocecal resection was performed, along with excision of the known mesenteric mass. The pathology report revealed an ileal NET with nodal metastases within the mesentery and mesenteric tumor deposits (pT3N1). CONCLUSIONS JI-NETs are rare entities, which are usually encountered as incidental findings or in patients with unspecific abdominal pain. Our case represents a probable delayed diagnosis of JI-NET in the context of sclerosing mesenteritis; therefore, a possible association between these 2 conditions should be investigated.BACKGROUND Nursing education is an important part of the "9+3" vocational education program led by Sichuan Province. In the internship stage, nursing students of Tibetan ethnicity may have problems of intercultural adaptation in the process of getting along with patients, which may affect the effective nursing outcome. The purpose of this study was to clarify the current situation of transcultural adaptation of Tibetan trainee nurses and to provide more theoretical support and guidance. MATERIAL AND METHODS We collected 237 valid survey questionnaires, based on Ward's acculturation process model, from a total of 363 Tibetan trainee nurses in the "9+3" free vocational education program in Chengdu, Luzhou, and Nanchong of Sichuan Province. The SPSSAU project (2020), an online application software retrieved from https//www.spssau.com, was used for data coding and archiving. RESULTS The results of questionnaire and data analysis showed that the overall level of transcultural adaptation of Tibetan trainee nurses was that the number of people with poor adaptation was slightly higher than those with good adaptation, and most Tibetan trainee nurses were in the middle level. Meanwhile, sociocultural adaptation was better than psychological adaptation. There were no statistically significant differences among the 4 grouping variables gender, student home region, the city where the internship hospital was located, and whether they were from a single-child family or not. CONCLUSIONS The results revealed that there was still transcultural maladjustment among Tibetan nurses in the internship stage, and the psychological maladjustment was more obvious than the sociocultural maladjustment.  https://www.selleckchem.com/products/amg510.html  We provide countermeasures and suggestions to solve the problems of transcultural adaptation reflected in the research.During 2020, increasing numbers of case reports, case series, and small observational studies reported long-term complications of coronavirus disease 2019 (COVID-19) in patients who had recovered from acute infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Long COVID has a prevalence of between 10-30% in patients with a recent history of SARS-CoV-2 infection. Pulmonary, hematologic, cardiovascular, neuropsychiatric, renal, endocrine, gastrointestinal and hepatobiliary, and dermatologic involvement, and chronic multisystem inflammatory syndrome in children (MIS-C) highlights the requirement for a multidisciplinary approach to the management of patients with long COVID. This Editorial aims to present the current status of long COVID, or post-COVID syndrome, and its global impact on health and the provision of health care.
