目的 研究母代不同孕期巨细胞病毒（CMV）感染对自身精神及行为的影响。方法 72只BALB/c雌鼠随机分为12组（A1、A2、A3、B1、B2、B3、C1、C2、C3、D1、D2、D3,每组6只）,A为孕期再感染、B为既往感染、C为孕期原发感染、D为空白对照,1为孕早期、2为孕中期、3为孕晚期。母鼠腹腔注射小鼠CMV（murine CMV,MCMV）Smith株建立播散性感染模型,或注射无菌生理盐水建立对照模型。母鼠产仔后同笼合养,产后22 d分笼;母鼠做行为学试验。试验结束,每组随机处死3只母鼠;测量子宫、肝、脑脏器重量系数及唾液腺中MCMV含量。结果 A、B、C组母鼠产后次日体质量均低于D组（均P<0.05）,其中C2、C3组母鼠低体质量情况持续至产后22日（均P<0.05）。A、B、C组母鼠唾液腺组织均测出MCMV。与D组母鼠相比,A1、C1组母鼠活胎率降低（均P<0.05）,A、C组母鼠的子宫、肝、脑脏器系数升高（均P<0.05）且脑组织有病损表现。产后6天时,A3、B3、C组母鼠水平运动总距离和直立次数减少（均P<0.05）,糖水偏好量降低（均P<0.05）,悬尾不动时间延长（P<0.05）;其中,C2、C3组母鼠以上行为退缩情况至产后22天仍存在,且有逃避潜伏时间延长（均P<0.01）,穿越原平台位置次数减少（均P<0.01）情况。结论 孕期CMV感染损害母代身心健康,有可能增加子代不良抚养的风险。

Objective To investigate the effects of cytomegalovirus（CMV）infection in different stages of maternal pregnancy on its own spirit and behavior．Methods A total of 72 female BALB/c mice were randomly divided into 12 groups（each group had 6 mice）：A1-A3,B1-B3,C1-C3,D1-D3（group A had re-infection,group B had previous infection,group C had primary infection,group D was blank control,group 1 was in early pregnancy,group 2 was in middle pregnancy,group 3 was in late pregnancy）．The disseminative infection model was established by intraperitoneal inoculation of murine CMV（MCMV）Smith strain,and the blank control model was established by intraperitoneal inoculation of 0.9% sterile saline（NaCl）．After 21 days of parturition,the mothers and offspring were reared in separate cages,mothers were selected for the behavior experiments．At the end of all the behavior tests,3 mothers in each group were killed randomly．Weighed and calculated the organ coefficients of the uteri,livers and brains,and detected the expression levels of MCMV in salivary gland．Results On the first day after delivery,the weights of mothers in groups A,B and C were lower than those in group D（all P<0.05）,the low body weight of mice in C2 and C3 groups lasted to the 22th day（all P<0.05）．The MCMV in salivary gland tissue were found in groups A,B and C,but not in group D．The live fetus rates of groups A1 and C1 were significantly lower than that of group D．The organ coefficients of uteri,livers and brains in groups A and C were higher than those in group D（all P<0.05）．And the lesions of brain tissues in groups A and C were more serious than in the other groups．On the 6th day,compared with the other groups,the mothers of groups A3,B3 and C were significantly abnormal in the open field test,the tail suspension test and the sugar preference test（all P<0.05）．But on 22th day,only the mothers of groups C2 and C3 were significantly abnormal in those tests（all P<0.01）,and even in the water maze test（all P<0.01）．Conclusions Maternal CMV infection in different stages pregnancy have impacts on mother mice's physical and mental health．Those bad situations may bring poor parenting to the offspring．

自身免疫性肝炎（AIH）是由不明原因免疫异常引起的急性或慢性肝脏炎症性疾病,不分年龄或性别,影响所有种族群体。AIH如果没有得到及时的治疗,可能会发展为肝硬化、肝衰竭,甚至导致死亡。目前一些诊断评分系统和肝活组织病理检查已成为诊断的标准,然而由于疾病表现的高度异质性,AIH诊断仍很有挑战性。大多数患者最初对一线治疗（糖皮质激素与硫唑嘌呤的联合治疗）有应答,然而,应答欠佳和因不良反应引起的不耐受也不少见,需要二线和（或）三线治疗。本文总结阐述诊断困难、一线药物治疗应答欠佳或不耐受的疑难AIH诊断和管理的最新进展,并归纳了目前国内外关于AIH治疗的新方法,为AIH的临床诊疗提供参考。

Autoimmune hepatitis（AIH）is an acute or chronic inflammatory disease of liver caused by unclear immune response that affects people from all ethnic groups irrespective of age or sex．If left untreated,AIH will lead to cirrhosis,liver failure,or death．A number of diagnostic scoring systems and histopathological examination of liver biopsies are now the standard for diagnosis．However,due to the high heterogeneity of the disease presentation,AIH diagnosing remains challenging．Most patients initially respond to first-line treatment,which is corticosteroids combined with azathioprine．However,insufficient response and intolerance due to side effects are also common,so some patients requires second-and/or third-line therapies．Here we summarized the latest progress in diagnosis and management of AIH with difficult diagnosis,poor response to first-line drug treatment or intolerance,as well as the new methods of AIH treatment worldwide,to provide reference for the clinical diagnosis and treatment of AIH．

本文综述近10年中医传统疗法中通过穴位刺激预防与治疗老年患者骨折术后谵妄的研究概况。术后谵妄是老年患者骨折术后常见的并发症,不仅延长患者住院时间、增加经济负担,同时与骨折术后死亡并发症的发生密切相关。但是本病机制尚未明确,在临床治疗上难以达成共识。针灸等穴位刺激是中医药治疗脑病的独具特色的疗法,近年来有关穴位刺激防治老年骨折术后谵妄的报道越来越多,本文主要探讨不同的穴位刺激方法干预对骨折术后谵妄发生率的影响,包括传统刺激方式如毫针、电针、穴位注射、穴位敷贴和新针疗法如耳针、头针等,认为穴位刺激能够较好预防骨折术后谵妄发生,在治疗上也有较好疗效。以期为进一步临床研究与应用提供参考。

This article summarized the research of acupoint stimulation in preventing delirium after fracture surgery in elderly patients in recent 10 years．Postoperative delirium is a common complication in elderly patients after fracture surgery, which affects life extremely and increases economic burden．However, the mechanism of this disease haven't been revealed, and it is difficult to reach consensus on clinical treatment．Acupoint stimulation, like acupuncture, is a unique treatment of encephalopathy with traditional Chinese medicine．In recent years, there are more and more reports on acupoint stimulation therapy to prevent and treat delirium after fracture surgery in the elderly．This article mainly study the influence of different acupoint stimulation therapy on treatment of delirium after fracture surgery, including electroacupuncture, auriculotherapy, scalp acupuncture, acupoint injection and acupoint application, etc．It is believed that acupoint stimulation can prevent delirium after fracture surgery, so as to provide reference for further clinical research and application．

我国结直肠癌的发病率与死亡率逐年增加,约10%~30%新发结直肠癌患者可表现为急性肠梗阻,其中梗阻发生率较高的主要部位是左半结肠。急性梗阻性左半结肠癌患者的主要治疗方式仍是急诊手术（ES）,但术后并发症发生率及围手术期死亡率较高,自膨式金属支架（SEMS）被一些指南推荐为梗阻性结肠癌的初始治疗选择,SEMS可将部分ES转变为择期手术,支架置入后择期手术（SBTS）与ES相比不仅可改善患者的短期生存结局,且支架置入后新辅助化疗为梗阻性结肠癌的治疗提供了新的途径;就长期生存结果而言,选择SBTS还是ES存在一定的争议。对于支架置入后手术时机的选择尚未达成共识,有指南表明大约两周的短桥接间隔可使患者最大程度获益,因而可有效指导临床工作。肠道支架置入术目前看来是一种简单、有效的临时性或永久性的治疗手段。

In recent years, the incidence and mortality of colorectal cancer in our country have been increasing year by year．Around 10% to 30% of newly diagnosed colorectal cancer patients showed acute intestinal obstruction, which the left colon cancer has higher incidence．Emergency surgery（ES）is still the main treatment for patients with acute obstructive left colon cancer, but the incidence of postoperative complications and perioperative mortality are high．Self-expanding metallic stents（SEMS）can convert some emergency procedures into stent as bridge to surgery（SBTS）, which is recommended by some guidelines as the initial treatment option for obstructive colon cancer．SBTS can not only improve the short-term survival outcome of patients compared with ES, but also provide a new approach for the treatment of obstructive colon cancer with neoadjuvant chemotherapy after intestinal obstruction stent placement．The choice of SBTS versus ES is somewhat controversial in terms of long-term survival outcomes．There is no consensus on the timing of surgery after stenting, and current guidelines suggest that bridging intervals of approximately two weeks strike a balance between potential adverse events and long-term outcomes．At present, intestinal stenting is still a simple, feasible and effective temporary or palliative permanent treatment with few complications．
