海口高校大学生健康素养现况调查及影响因素分析

目的 了解在"国家卫生城市"等一系列创建示范工作背景下海口高校大学生健康素养现况及影响因素,为有关部门制定健康教育策略和措施提供科学依据.方法 采用分层整群抽样方法于2020年9～11月从海口市内随机抽取两所全日制高校1812名本科生进行问卷调查,不同特征人群的健康素养水平比较采用χ2检验,影响因素采用二分类变量的Logistic回归分析.结果 海口高校大学生健康素养水平为51.16％,健康素养3个方面的具备率由高到低依次为基本知识与理念(63.85％)、健康生活方式与行为(36.31％)、基本健康技能(33.66％).由二元Logistic回归分析得出专业、民族、户籍及是否吸烟是影响高校大学生健康素养的主要因素(P<0.05).结论 海口高校大学生健康素养水平高于全国大学生平均水平,但各维度的知晓率差异较大,学生专业、民族、户籍所在地、是否吸烟为影响因素.相关部门应针对薄弱环节,调整教育卫生知识结构,进一步提升学生健康知识水平.     

经皮椎体成形术导致巨大腹膜后血肿成功救治1例报道

经皮椎体成形术是一种安全有效的微创手术,腹膜后血肿是其罕见但严重的并发症。我们报告一例经皮椎体成形术RH阴性(熊猫血)患者术后并发巨大腹膜后血肿,经保守和输血等支持治疗,病人康复出院。脊柱医生应了解这种罕见但潜在致命的并发症,因为早期认识和及时预防是降低其发病率的基础。     

Role of surgical treatments in high-grade or advanced gastroenteropancreatic neuroendocrine neoplasms

Over the last 40 years, the incidence and prevalence of gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) have continued to increase. Compared to other epithelial neoplasms in the same organ, GEP-NENs exhibit indolent biological behavior, resulting in more chances to undergo surgery. However, the role of surgery in high-grade or advanced GEP-NENs is still controversial. Surgery is associated with survival improvement of well-differentiated high-grade GEP-NENs, whereas poorly differentiated GEP-NENs that may benefit from resection require careful selection based on Ki67 and other tissue biomarkers. Additionally, surgery also plays an important role in locally advanced and metastatic disease. For locally advanced GEP-NENs, isolated major vascular involvement is no longer an absolute contraindication. In the setting of metastatic GEP-NENs, radical intended surgery is recommended for patients with low-grade and resectable metastases. For unresectable metastatic disease, a variety of surgical approaches, including cytoreduction of liver metastasis, liver transplantation, and surgery after neoadjuvant treatment, show survival benefits. Primary tumor resection in GEP-NENs with unresectable metastatic disease is associated with symptom control, prolonged survival, and improved sensitivity toward systemic therapies. Although there is no established neoadjuvant or adjuvant strategy, increasing attention has been given to this emerging research area. Some studies have reported that neoadjuvant therapy effectively reduces tumor burden, improves the effectiveness of subsequent surgery, and decreases surgical complications.     

幽门螺杆菌感染相关因素的研究进展

幽门螺杆菌（HP）是革兰阴性微需氧的螺旋样杆菌，主要通过口-口途径在人-人之间感染传播。HP的发现加深了人类对慢性感染、炎症和癌症之间关系的认识。其特定的螺旋形体型、鞭毛及动力、尿素酶和黏附素活性，以及细胞毒素基因A（cagA）、空泡细胞毒素基因A（vacA）等是影响HP感染研究较多的相关致病因素。HP感染在胃癌的发生、发展中可能具有重要作用，但尚未确切证实HP感染是导致胃癌的主因。文章概述了HP感染相关致病因素的研究进展。     

First-line nivolumab plus chemotherapy vs chemotherapy in patients with advanced gastric,gastroesophageal junction and esophageal adenocarcinoma: CheckMate 649 Chinese subgroup analysis

First-line chemotherapy for advanced/metastatic human epidermal growth factor receptor 2 (HER2)-negative gastric/gastroesophageal junction cancer (GC/GEJC) has poor median overall survival (OS; <1 year). We report efficacy and safety results from Chinese patients in the phase III global CheckMate 649 study of nivolumab plus chemotherapy vs chemotherapy for the first-line treatment of GC/GEJC/esophageal adenocarcinoma (EAC). Chinese patients with previously untreated advanced or metastatic GC/GEJC/EAC were randomized to receive nivolumab (360 mg Q3W or 240 mg Q2W) plus chemotherapy (XELOX [capecitabine and oxaliplatin] Q3W or FOLFOX [oxaliplatin, leucovorin and 5-fluorouracil] Q2W), nivolumab plus ipilimumab (not reported) or chemotherapy alone. OS, blinded independent central review-assessed progression-free survival (PFS), objective response rate (ORR), duration of response (DOR) and safety are reported. Of 1581 patients enrolled and randomized, 208 were Chinese. In these patients, nivolumab plus chemotherapy resulted in clinically meaningful improvement in median OS (14.3 vs 10.2 months; HR 0.61 [95% CI: 0.44-0.85]), median PFS (8.3 vs 5.6 months; HR 0.57 [95% CI: 0.40-0.80]), ORR (66% vs 45%) and median DOR (12.2 vs 5.6 months) vs chemotherapy, respectively. The safety profile was acceptable, with no new safety signals observed. Consistent with results from the global primary analysis of CheckMate 649, nivolumab plus chemotherapy demonstrated a clinically meaningful improvement in OS and PFS and higher response rate vs chemotherapy and an acceptable safety profile in Chinese patients. Nivolumab plus chemotherapy represents a new standard first-line treatment for Chinese patients with non-HER2-positive advanced GC/GEJC/EAC.

基于“大病以胃”思想诊治新型冠状病毒肺炎的肺脾相关性探讨

注重胃气是中医学独特的诊疗特色。“大病以胃”思想是山西门氏杂病流派治疗疑难疾病的一项重要治则。“大病”之“大”，既指疾病的病程，又指症状、病情、预后等。在新型冠状病毒肺炎(corona virus disease 2019, COVID-19)诊治过程中，要充分认识到新型冠状病毒肺炎的病位不仅在肺，同时也在脾，与宗气相关。治疗时当从人体整体功能状态出发，肺脾同调，扶助胃气，调整脏腑功能，增强宗气，促进患者机体恢复正常的功能状态，从而治愈疾病。“大病以胃”思想作为中医药传承几千年形成的经典理论，是中医实证精华，是秉承中医最好的表达。“大病以胃”思想可为COVID-19的诊疗提供新的诊疗思路。
