2013-2017年我国四种恶性肿瘤住院费用水平及结构变动度分析

背景　恶性肿瘤给家庭、社会带来了沉重的医疗、经济负担，极易导致部分家庭“因病致贫”或放弃治疗，目前相关研究多集中于单一病种、分散地域的研究，仍缺乏对于全国范围与多病种恶性肿瘤住院费用变化及结构构成的考量。目的　分析2013-2017年我国4种恶性肿瘤住院费用水平以及影响住院费用的主要项目和结构变动情况，为控制医疗费用上涨、深化新医改提供参考依据。方法　本研究数据来源于《2014中国卫生和计划生育统计年鉴》《2015中国卫生和计划生育统计年鉴》《2016中国卫生和计划生育统计年鉴》《2017中国卫生和计划生育统计年鉴》以及《2018中国卫生健康统计年鉴》，样本跨度为2013-2017年。统计“30种疾病人均住院费用”中的胃恶性肿瘤、肺恶性肿瘤、食管恶性肿瘤以及膀胱恶性肿瘤的数据，4种恶性肿瘤的人均住院费用包括药费、检查费、治疗费、手术费和手术材料费。2019年4-8月，采用结构变动度法分析我国2013-2017年4种恶性肿瘤的住院费用的结构变动情况〔结构变动值（VSV）、结构变动度（DSV）、结构变动贡献率〕。结果　2013-2017年，4种恶性肿瘤的人均住院费用逐年上升，其中胃恶性肿瘤的人均住院费用始终最高，且肺恶性肿瘤的人均住院费用上升幅度最大。2013-2017年，在4种恶性肿瘤住院各项费用的占比中，药费占比最高且总体逐年下降。从4种恶性肿瘤住院各项费用的实际变化来看，药费在2013-2014年有所上升，2014-2017年逐年下降；检查费在2013-2014年下降，2014-2017年缓慢上升；手术费与手术材料费在2013-2017年逐年上升。2013-2017年，在4种恶性肿瘤住院各项费用中均是药费的VSV最大；4种恶性肿瘤药费、检查费的VSV均呈负向变化，手术费和手术材料费的VSV均呈正向变化，治疗费的VSV增减均不明显。2013-2017年，4种恶性肿瘤住院费用的DSV从大到小依次为肺恶性肿瘤、胃恶性肿瘤、食管恶性肿瘤、膀胱恶性肿瘤。2013-2017年，4种恶性肿瘤住院各项费用中均是药费的结构变动贡献率最大，治疗费的结构变动贡献率最小；除药费外，胃恶性肿瘤、肺恶性肿瘤住院各项费用中均是手术材料费和手术费的结构变动贡献率次之，食管恶性肿瘤住院各项费用中手术费、检查费的结构变动贡献率次之，膀胱恶性肿瘤住院各项费用中检查费、手术材料费的结构变动贡献率次之。结论　2013-2017年我国4种恶性肿瘤手术费的结构变动贡献率虽然较为理想，但药费、治疗费仍是住院费用结构的重点调整对象；同时为有效降低恶性肿瘤的人均住院费用，应当加强控制手术材料费与检查费；而胃恶性肿瘤与肺恶性肿瘤患者的疾病经济负担严重，若要缓解应加强疾病的早期预防与住院费用管控。     

尿石症与骨质疏松相关性的研究进展

尿路结石与骨质疏松均存在钙代谢异常,且发病率高,对生活质量造成严重影响,研究表明两者之间存在一定相关性。高钙尿症通过骨吸收增加等,或为两者发病机制间的关键桥梁。对遗传因素的研究中也发现了许多与两者有关的基因,主要为腺苷酸环化酶10基因、1,25-(OH)2D3-24羟化酶基因、钙敏受体与紧密连接蛋白14基因。但对上述一些基因变异与尿石症和骨质疏松的研究尚存在不同结论,且其具体机制仍待进一步研究。雌激素缺乏通过骨丢失、减少瞬时感受器电位阳离子通道V5表达,造成高钙尿、低骨量,导致尿石症及骨质疏松。高蛋白、高钠、低钙等饮食因素也能影响两者的形成,笔者综述两者之间相关性的研究进展。     

Aging changes agonist induced contractile responses in permeabilized rat bladder

Aging alters bladder functions where a decrease in filling, storage and emptying is observed. These changes cause urinary incontinence, especially in women. The aim of this study is to examine how aging affects the intracellular calcium movements due to agonist-induced contractions in permeabilized female rat bladder. Urinary bladder isolated from young and old female Sprague-Dawley rats were used. Small detrusor strips were permeabilized with β-escin. The contractile responses induced with agonists were compared between young and old groups. Carbachol-induced contractions were decreased in permeabilized detrusor from old rats compared to young group. Heparin and ryanodine decreased carbachol-induced contractions in young rats where only heparin inhibited these contractions in olds. Caffeine-induced contractions but not inositol triphosphate (IP₃)-induced contractions were decreased in old group compared to youngs. The cumulative calcium response curves (pCa 8–4) were also decreased in old rats. Carbachol-induced calcium sensitization responses did not alter by age where GTP-β-S and GF-109203X but not Y-27632 inhibited these responses. Carbachol-induced contractions decrease with aging in rat bladder detrusor. It can be postulated as IP₃-induced calcium release (IICR) is primarily responsible for the contractions in older rats where the decrease in carbachol contractions in aging may be as a result of a decrease in calcium-induced calcium release (CICR), rather than carbachol-induced calcium sensitization.     

Efficacy of percutaneous and transcutaneous tibial nerve stimulation in women with idiopathic overactive bladder: A prospective randomised controlled trial

BackgroundDifferent studies have reported the efficacy of percutaneous tibial nerve stimulation (PTNS) and transcutaneous tibial nerve stimulation (TTNS) in treating idiopathic overactive bladder (OAB). However, no study has compared the effectiveness of PTNS and TTNS added to bladder training (BT) in idiopathic OAB.ObjectiveTo compare the efficacy of PTNS and TTNS added to BT in women with idiopathic OAB.MethodsWe randomised 60 women with idiopathic OAB into 3 groups. Group 1 (n = 19) received BT, Group 2 (n = 19) received PTNS in addition to BT, and Group 3 (n = 20) received TTNS in addition to BT. PTNS and TTNS were performed 2 days a week, for 30 min a day, for a total of 12 sessions for 6 weeks. Patients were evaluated by incontinence severity (pad test), a 3-day voiding diary (frequency of voiding, incontinence episodes, nocturia and number of pads used), symptom severity, quality of life, treatment success (positive response rate), treatment satisfaction (Likert scale), discomfort level and preparation time for stimulation (sec).ResultsAt the end of treatment; severity of incontinence, frequency of voiding, incontinence episodes, nocturia, number of pads used, symptom severity and quality of life were significantly improved in Groups 2 and 3 versus Group 1 (P < 0.0167). Treatment success and treatment satisfaction were higher in Groups 2 and 3 than Group 1 (P < 0.001 and P < 0.0167, respectively). Level of discomfort was lower, treatment satisfaction was higher and preparation time for stimulation was shorter in Group 3 than Group 2 (P < 0.05).ConclusionBoth the PTNS plus BT and TTNS plus BT were more effective than BT alone in women with idiopathic OAB. These 2 tibial nerve stimulation methods had similar clinical efficacy but with slight differences: TTNS had shorter preparation time, less discomfort level and higher patient satisfaction than PTNS.     

The practical assessment and management of bladder outflow obstruction

The initial management of bladder outflow obstruction typically related to benign prostatic hyperplasia (BPH) falls to a large extent within the remit of general practice. Referral onwards to secondary care typically arises following the failure to respond to conservative measures or when complications have supervened; the most significant of which is urinary retention. In the hospital setting, anaesthesia, constipation and immobility are the common precipitants. What follows is a practical guide to the management of these situations and provides an overview of the conservative, medical, minimally invasive and surgical treatments available.     

The role of WNT signalling in urothelial cell carcinoma

Urothelial cell carcinoma (UCC) of the bladder is one of the most common malignancies, causing considerable morbidity and mortality worldwide. It is unique among the epithelial carcinomas as two distinct pathways to tumourigenesis appear to exist: low grade, recurring papillary tumours usually contain oncogenic mutations in FGFR3 or HRAS whereas high grade, muscle invasive tumours with metastatic potential generally have defects in the pathways controlled by the tumour suppressors p53 and retinoblastoma. Over the last two decades, a number of transgenic mouse models of UCC, containing deletions or mutations of key tumour suppressor genes or oncogenes, have helped us understand the mechanisms behind tumour development. In this summary, I present my work investigating the role of the WNT signalling cascade in UCC.     

CSTB、A-FABP在膀胱癌诊断与预后的价值

目的 分析CSTB、A-FABP在膀胱癌诊断和预后的意义。方法 选取2014年1月至2016年7月在本院进行手术、病理证实的膀胱癌患者45例、良性膀胱病变患者88例，检测膀胱癌样本癌组织、癌旁组织、良性膀胱病变组织中CSTB、A-FABP表达水平。评价CSTB、A-FABP在鉴别诊断膀胱癌的效用。对比膀胱癌进展对象（2年内转移、复发、肿瘤死亡）以及未进展对象组织中CSTB、A-FABP表达水平。结果 癌组织、癌旁组织、良性病变对象组织中CSTB、A-FABP表达水平差异有统计学意义（P<0．05）。CSTB、A-FABP作为诊断标准（任意一项为阳性），鉴别诊断膀胱癌与良性病变的灵敏度为84．4%、特异度为90．9%、阳性预测值82．6%、阴性预测值92．0%、符合率88．7%。2年内转移、复发、肿瘤死亡的患者共30例，无转移、复发、死亡的患者共15例，膀胱癌进展对象CSTB、A FABP表达量高于未进展对象，差异有统计学意义（P<0．05）。结论 CSTB、A-FABP在膀胱癌诊断、预后预测中均有一定的临床价值。     

膀胱癌的~(18)F-FDG PETCT显像诊断价值研究

目的研究~(18)F-FDG PETCT显像对膀胱癌的诊断价值。方法选取我院核医学科2013年3月-2015年2月收治的34例可疑膀胱癌患者,术前分别采用增强CT和~(18)F-FDG PETCT显像进行诊断,通过参考手术病理结果回顾性分析~(18)F-FDG PETCT显像诊断的效果。结果该34例经手术病理观察均确诊为移行细胞癌,增强CT、~(18)F-FDG PETCT显像诊断准确度分别为91.18%、94.12%,差异无统计学意义(P0.05);术中共有11例膀胱肿瘤出现盆腔淋巴结或邻近组织转移、浸润,~(18)F-FDG PETCT显像诊断准确度为72.73%,明显高于增强CT(27.27%),具有统计学意义(P0.05)。结论 ~(18)F-FDG PETCT显像和增强CT均是临床诊断膀胱癌的有效方法,但~(18)F-FDG PETCT显像在观察膀胱肿瘤病灶的转移和对邻近组织的浸润效果较好,对指导临床诊断和了解肿瘤病变具有重要参考价值。
