Background: Recent.report. suggest.t.at.Helicobact.r pylori infect.on can pot.nt.ally increase t.e risk of colorect.l cancer. t.e purpose of t.is st.dy was t. assess t.e associat.on bet.een H. pylori infect.on and t.e risk of colorect.l adenoma and adenocarcinoma, and t. evaluat. any differences on t.e basis of sex. Met.ods: t.e subject. were 669 (40-t. 80-year-old) pat.ent. who underwent.bot. barium enema examinat.on and t.t.l colonoscopy, and who were evaluat.d for H. pylori infect.on by 13C-urea breat. t.st. urease t.st. or hist.logical diagnosis of biopsied gast.ic specimens. t.ere were 142 H. pylori-negat.ve and 527-posit.ve pat.ent.. t.e odds rat.os (ORs) for H. pyloriposit.ve pat.ent. wit. colorect.l adenoma and adenocarcinoma, and for t.mor pat.ent. wit. eit.er adenoma or adenocarcinoma were calculat.d. Result.: Among t.e H. pylori-negat.ve pat.ent., t.ere were 52 pat.ent. wit.out.t.mor, 63 wit. adenoma, 27 wit. adenocarcinoma, and 90 wit. t.mor. Among t.e H. py-lori-posit.ve pat.ent., t.ere were 136, 264, 127, and 391 pat.ent. respect.vely. Pooling all subject., t.ose infect.d wit. H. pylori had a significant.y increased OR for adenoma, adenocarcinoma, or t.mor, compared t. H. pylori-free pat.ent. (OR, 1.60, 1.80, and 1.66, respect.vely). For female H. pylori-posit.ve subject., t.e risk of having adenocarcinoma or t.mor was significant.y higher t.an t.at.for t.eir H. pylori-free count.rpart., while for male H. pylori-posit.ve and -negat.ve subject., t.ere was no such significant.difference. Conclusions: t.e result. t.erefore suggest.t.at. in pat.ent. aged 40-80 years, H. pylori infect.on increased t.e risk of colorect.l adenoma and adenocarcinoma, wit. significant.y higher risks for female pat.ent..

Background: Women are t.ought.t. be more suscept.ble t. st.ess t.an men in a st.essful societ., and reducing st.ess is crucial for women t. maint.in t.eir healt.. St.t.c st.et.hing (SSt. is applied in various fields t. not.only increase muscle flexibilit. but.also reduce st.ess. Addit.onally, conscious slower breat.ing (CSB) predominat.s parasympat.et.c act.vit., causing a relaxing effect. t.ese result. indicat. t.at.combining SSt.and CSB may be more useful in reducing st.ess. However, t. t.e best.of our knowledge, t.e effect.of t.is combinat.on remains unclear. Object.ve: t.is st.dy aimed t. elucidat. t.e effect. of t.e combinat.on of SSt.and CSB on aut.nomic act.vit. and st.ess in adult.women. Met.ods: Eleven healt.y Japanese adult.female part.cipant. performed SSt.wit. nonconscious nat.ral breat.ing for 20 min. t.e same part.cipant. performed SSt.in combinat.on wit. CSB (2 s inspirat.ry and 4 s expirat.ry) for 20 min on anot.er day. Salivary cort.sol and chromogranin A levels were measured before and aft.r st.et.hing as st.ess markers of t.e hypot.alamic-pit.it.ry-adrenal axis and sympat.et.c nervous syst.m. t.e coefficient.of variat.on of t.e R-R int.rval (CVR-R) and high-frequency component.(HF), which reflect.parasympat.et.c nerve act.vit., and heart.rat. and low-frequency component.(LF)/HF rat.o, which reflect.sympat.et.c nerve act.vit., were measured before, during, and aft.r st.et.hing. Result.: SSt.decreased cort.sol levels but.wit. no significant.changes in chromogranin A, heart.rat., CVR-R, HF, or LF/HF rat.o. t.e combinat.on of SSt.and CSB increased CVR-R and HF levels in addit.on t. decreasing cort.sol levels but.wit. no significant.changes in chromogranin A, heart.rat., or LF/HF levels. Conclusion: t.ese result. indicat. t.at.t.e combinat.on of SSt.and CSB may increase parasympat.et.c act.vit. and reduce st.ess. However, fut.re randomized cont.olled t.ials wit. larger sample sizes should support.t.is conclusion.

近年来,简牍研究的理论内容高速发展,并集中于“简牍学”的形成。在这样的大背景下,中国的简牍研究者开始着眼于国外的简牍研究成果也实属必然。日本木简的研究成果总量十分庞大,并且研究分类十分细致。马场基所著的《日本古代木简论》着重展现、推进了东亚研究视野下的木简研究,充分体现了现阶段日本木简研究最前沿的成果。本文认为,马场氏的研究方式或许蕴含着能给中国的简牍研究带来全新的视角和研究方式的可能性。本文通过马场氏著作的相关讨论,对如何将日本木简研究中的方法应用至中国简牍研究进行探讨。
