Objective: Real-world diagnostic and treatment data for pancreatic cancer in China are lacking. As such, the present study investigated the clinical characteristics, diagnosis, and treatment of advanced pancreatic cancer (including locally advanced and metastatic disease) in the Hospital-based Advanced Pancreatic Cancer Cohort in China of the China Pancreas Data Center ***: A total of 5349 Chinese patients with advanced pancreatic cancer were identified from a database. The entire course of real-world pancreatic cancer management was ***: The proportion of patients with advanced pancreatic cancer was higher among males than females (62.4% vs 37.6%, respectively). Patients typically had a history of hypertension (30.8%), diabetes (21.6%), and cholangitis (20.2%). Abdominal pain (51.6%), abdominal distension (27.1%), jaundice (20.1%), and weight loss (16.3%) were the main symptoms observed in patients with advanced pancreatic cancer in this cohort. Serum carbohydrate antigen (CA)19-9 is one of the most common tumor markers. In the present study, 2562 patients underwent first-line therapy. The median progression-free survival (PFS) for patients undergoing first-line therapy was 4.1 months. The major options for first-line therapy included gemcitabine (GEM) plus S-1 (GS/X) (23.4%), nab-paclitaxel plus GEM (AG) (18.1%), oxaliplatin, irinotecan, and leucovorin-modulated fluorouracil (FOLFIRINOX; 11.9%), nab-paclitaxel plus S-1 (AS) (8.9%), and GEM combined with oxaliplatin/cisplatin (GEMOX/GP) (7.6%). The AS and GS/X regimens were associated with the highest PFS ***: This is the first study to report multicenter, real-world data regarding advanced pancreatic cancer in China. Results revealed that real-world treatment options differed from guideline recommendations, and PFS was shorter than that in previously reported data. Improving intelligent follow-up systems and standardizing diagnosis and treatment of pancreatic cancer is recomm

由于气候变化以及城市化发展,引起强降雨等极端天气事件增多,导致城市内涝现象加剧,给城市交通、居民生活和基础设施造成严重影响。基于MIKE FLOOD平台,通过耦合MIKE 11、MIKE URBAN和MIKE 21三个模型,构建了暴雨内涝模型,对深圳市大空港片区内涝问题进行分析。利用2018年“山竹”台风实测暴雨条件下的实测水位、积水深度数据,对模型进行了参数率定和验证。在不同降雨情景下,内涝高风险区域主要集中位于研究区的中部区域以及河流沿岸附近。另外,根据“8·29”实测暴雨潮水位,模拟可得:大空港片区内涝点积水深度在15 cm以上的总积水面积约为7.11 hm^(2)。研究结果可为区域城市内涝防治提供科学的技术支撑。

目的:应用网状Meta分析方法比较与评价疏肝解郁类经典名方治疗心脏神经官能症(CN)的临床疗效及安全性。方法:计算机检索中国知网(CNKI)、中国生物医学文献数据库(CBM)、万方数据库(WanFang Data)、PubMed、the Cochrane Library、Web of Science数据库中关于柴胡加龙骨牡蛎汤、柴胡疏肝散、丹栀逍遥散、逍遥散单独或联合西医常规治疗CN的随机对照试验(RCT),检索时限为自建库至2022年10月26日。对纳入文献进行评估和筛选,并完成资料提取。运用RevMan 5.4进行文献质量评价、Stata 17.0进行网状Meta分析。结果:纳入35项研究,涉及病人3 094例,研究涉及的干预措施共9种,其中有34项研究以临床总有效率为主要结局指标,9项研究以汉密尔顿焦虑量表(HAMA)评分为次要结局指标,9项研究以不良反应发生率为次要结局指标。网状Meta结果显示,在临床总有效率上,逍遥散治疗效果更佳;在改善HAMA评分上,丹栀逍遥散+西医常规治疗效果更佳。在安全性上,丹栀逍遥散+西医常规治疗不良反应发生率更低。结论:临床上治疗CN,不仅要疏肝解郁,还需辅以健脾益气,且联合西医常规治疗可提高临床疗效,降低不良反应事件发生率。但是,基于本研究的局限性,需要更多高质量、多样本、多结局指标的研究进一步验证。
