不同特征女性人工流产时焦虑、抑郁情绪及影响因素

目的:研究不同特征女性人工流产时焦虑、抑郁情绪评估及影响因素。方法:以2019年1-7月在本院择期行人工流产者105例,其中已婚54例、未婚51例,手术流产62例、药物流产43例。采用焦虑自评量表(SAS)和抑郁自评量表(SDS)评价并比较不同特征者人工流产前焦虑及抑郁程度,多因素logistic分析可能影响因素。结果:不同婚姻状态、文化程度、孕次、产次、流产方式者发生术前焦虑及抑郁程度存在差异(P<0.05),不同年龄、流产次数者术前焦虑及抑郁程度评分未见差异(P>0.05);未婚及手术流产者术前焦虑及抑郁情况最高(P<0.05)。多因素分析,流产妇女婚姻状态、文化程度、产次、孕次以及流产方式均为产生术前焦虑情绪的独立危险因素。结论:未婚及手术流产者流产前负面情绪较高,提示临床在行人工流产中,及时开展健康教育,做好咨询工作,降低流产妇女的负面情绪,提升生殖健康质量。

目的 :根据阻塞性睡眠呼吸暂停综合征 (obstructivesleepapneasyndrom ,OSAS)患者多导睡眠仪(polysomnography ,PSG)监测信号 ,研究OSAS患者快速眼动睡眠损伤的特点。方法 :( 1)使用呼吸事件新分型法对 33例OSAS患者及正常打鼾者PSG监测信号进行分型 ,根据Ⅱ、Ⅲ型曲线的发生率将 33例OSAS患者分为轻度 ,中度和重度阻塞性呼吸暂停 3组 ;( 2 )比较 3组患者REM期睡眠时间长度 ;REM期呼吸紊乱特点。结果 :( 1) 3组患者REM期睡眠时间分别为 37.9± 11.3min ;12 .8± 3.1min ;7.3± 3.6min ,轻度组患者REM期睡眠时间较长 ,重度组患者REM期睡眠时间短 ,且易消失 ;( 2 )轻度组患者REM期RDI、RIT及SIT90 指数均较NREM期加重 ;重度组患者REM期RDI指数较NREM期显著减少 ,但RIT及SIT90 指数REM和NREM差异无显著性。结论 :( 1)根据新分型进行病情轻重分类能够反映患者REM期的损害程度 ,病情较重的患者REM期减少甚至消失 ;( 2 )轻度组患者REM期病情较NREM期加重 ,表现为RDI、RIT及SIT90 指数均显著增加 ;重度组患REM期较NREM期RDI减少 ,但呼吸及血氧损害程度无显著变化 ,显然是REM期呼吸紊乱的平均持续时间延长所致     

The relationship between apoptosis and the expression of proliferating cell nuclear antigen and the clinical stages in gastric carcinoma

Studies indicated that apoptosis and proliferat-ing cell nuclear antigen( PCNA) might present thetumor's biological characteristics on the molecularlevel[1,2 ] .The abnormal apoptosis and proliferationmight play an important role in the development ofgastric carcinoma[3 ,4 ] ,butthe implication ofapoptosisand PCNA in the clinical stages of gastric carcinomawere very little studied.By using terminal deoxynu-cleotidyl transferase- mediated nick and labelling( TUNEL) technique and PCNA immu…     

Initial treatment of the early stages (I, II) of supraglottic squamous cell carcinoma: partial laryngectomy versus radiotherapy

The purpose of this study was to define the treatment of choice (partial laryngectomy vs radiotherapy) in the early stage of supraglottic squamous cell cancer (ESSC). One hundred and fifteen patients with ESSC were treated with either partial laryngectomy (25 patients) or with radiotherapy(90 patients) between January 1984 and December 1996. All patients had a follow-up of over ¶29 months. Radiotherapy (RT) had a local control rate of 79%, which increased to 90% with salvage surgery, and a high larynx preservation rate (83%). Partial laryngectomy (PL) offered a better initial local control rate of 84%, which increased to 88% with salvage surgery, and functional results were also good (80%). No statistically significant differences were found between RT and PL. RT was less costly, showed better suitability for treatment, produced moderate morbidity and sequelae, and local recurrence was easier to rescue. However, it is a once-only application technique. PL showed higher immediate postoperative morbidity, higher cost and lower suitability for treatment but had fewer sequelae, offered the best initial local control and is multi-applicable. No clear oncological arguments were found in our series to define whether PL or RT is the treatment of choice for ESSC. Both are effective therapies. Secondary factors such as suitability for treatment, morbidity, cost and applicability should be individually evaluated when choosing the type of treatment. As the laser endoscopic approach decreases morbidity and costs and makes the condition more suitable for treatment, it could be the treatment of choice for ESSC, in cases where local tumoral extent and larynx exposure allow radical excision.

Nocturnal plasma thyrotropin variations are related to slow-wave sleep

SUMMARY  The thyrotropin (TSH) nycthemeral pattern is known to be strongly influenced by sleep, but previous studies have failed to demonstrate any link between sleep structure and TSH variations. Using 10-min blood sampling, nocturnal TSH profiles were analysed in 24 young healthy subjects during normal sleep. Six of the subjects then underwent a partial sleep deprivation experiment, sleep was permitted from 03.00 hours to 07.00 hours. Descending slopes of TSH values were observed for the first 20 minutes of SWS episodes, whereas no significant trend was found for other sleep stages. During the period of sleep deprivation, nocturnal TSH levels increased and then declined immediately after sleep onset; however, the association between SWS and descending TSH slopes persisted. This temporal concordance suggests that some particular mechanisms associated with SWS may modulate TSH release, or conversely that increasing TSH levels prevent the occurrence of SWS.     

命门动静观——兼论中医关于内分泌学的早期发现

明代命门学说的形成是中国古代医家为探索生命的起源及其内在规律所作的伟大尝试,反映出中国医药学早期对人体内分泌功能的发现和认识[1]。明代医家关于命门的解剖位置及其功能的描述,与现代医学肾上腺的位置和生理功能基本相合。"命门动静观"——即命门是五脏整合的生殖调节中枢,平时处在半关闭的状态,静以蓄养,为生殖作物质和能量方面的储备;激发态下命门全面开放,整合脏腑,使之同步;奇经八脉为命门开放、整合五脏的通道。命门为生命之原,相火之主,具有阴阳相济的特性,因而有别于五脏、十二经脉,反映出太极层次下生命活动的内在规律和调节机制。这项研究澄清了长期以来"肾命不分"的混淆。命门学说研究的深入为在生命的高层次上探索中西医结合之路开辟了广阔的前景。
