腹腔镜下保留盆腔植物神经的解剖性广泛性子宫切除术37例临床分析

Objective To investigate feasibility of laparoscopic anatomical nerve sparing radical hysterectomy (LANSRH) used for locally advanced cervical cancer treatment and evaluate early recovery of bladder function postoperatively. Methods From October 2006 to September 2007, 37 cervical cancer patients with stage Ⅰb1 to Ⅱ a underwent LANSRH(LANSRH group) with pelvic lymphadenectomy matched 25 patients with cervical cancer treated by general laparoscopic radical hysterectomy (LRH,LRH group) with pelvic lymphadenectomy. The data of operating time, blood loss, numbers of lymph node, the length of resected vaginal and paracervix tissue were collected and compared. In the mean time, postoperative recovery of bladder function was evaluated. Results The laparoscopic anatomic nerve-sparing procedure was performed successfully and safely among all patients. (1) There was no remarkable difference in the following clinical parameters between LANSRH and LRH group: median operating time [(175±41) min vs. (178±30) min, P=0.72 ], blood loss [(233±104)ml vs. (218±77) ml, P=0.06], numbers of lymph nodes (13±4 vs. 15±6, P=0.16), resected length of paracervix tissue [(3.6±0.5)cm vs. (3.7±0.6) cm, P=0.43], resected length of vaginal tissue [(3.5±1.0)cm vs. (3.5±0.8) cm, P=0.80]. (2) The mean time of the Foley catheter removed was (10.6±2.7)days(7-17 days)in LANSRH group and (17.2±4.2)days(9-25 days)in LRH group (P=0.02). After Foley catheter removed, 95% (35/37) presented bladder fulfilling sense, 86% (32/37) presented automatic micturition and urination emptying in LANSRH group. However, In LRH group, 88% (22/25) presented bladder fulfilling sense, 76% (19/25) presented automatic micturition and urination emptying. The bladder void function recovery were 68% (25/37) in class 0 and 3% (1/37) in class Ⅱ in LANSRH group, when compared with 40% (10/25) in class 0 and 12% (3/25) in class Ⅱ in LRH group, it reached statistical difference (P<0.05). In the mean time, there was no significant difference in Class Ⅰ bladder void function recovery, which were 24% (9/37) and 48% (12/25). (3) No surgery complications and blood transfusion were observed in LANSRH and LRH group. Postoperative pathology suggested that no tumor cell invasion occurred in paracervix tissue and lymph nodes. During the range of 11 to 19 months follow-up, all patients were alive without tumor recurrence and metastasis. Conclusion LANSRH is safe and feasible surgical management for cervical cancer at early stage and would improve the recovery of bladder voiding function postoperatively by sparing anatomical nerve.

HBeAg阳性感染孕妇妊娠期中晚期接受替比夫定治疗对HBsAg、HBeAg及抗-HBc胎盘透过率的影响

目的 观察HBeAg阳性、HBV DNA高复制慢性HBV感染孕妇的HBsAg、HBeAg和抗-HBc胎盘透过率,进一步明确替比夫定阻断母婴传播的机制.方法 回顾性分析在本院例行孕期检查以及产科分娩的HBeAg阳性、HBVDNA≥106 IU/mL的慢性HBV感染孕妇84例,根据阻断HBV母婴传播方式不同分为常规双重免疫阻断组(常规组,15例)和双重免疫+替比夫定阻断组(替比夫定组,69例).检测妊娠中晚期、分娩时母亲和新生儿脐带血清HBsAg、HBeAg及抗-HBc水平.结果 两组之间母亲及新生儿HBsAg、HbeAg和抗-HBc水平无统计学差异(孕妇分娩时:HBsAg P =0.058,HBeAg P=0.065,抗-HBc P=0.727;新生儿脐血:HBsAg P=0.761,HBeAg P=0.225,抗-HBc P=0.924),且两组之间的HBsAg和HBeAg胎盘透过率亦无统计学差异(分别为P=0.172,0.163).两组新生儿脐带血抗-HBc透过率均为阳性.结论 妊娠中晚期替比夫定不能降低孕妇HBsAg、HBeAg水平和HBsAg、HBeAg的胎盘透过率,其阻断HBV母婴传播的机制可能主要与有效降低孕妇HBV DNA水平有关.透过率与母亲HBsAg和HBeAg水平不成平行关系.

目的研究中国人群OX40配体蛋白基因(TNFSF4)单核苷酸多态性与高血压及其并发症的相关性。方法从北京同仁医院和北京朝阳医院选取高血压病患者296例和匹配的对照组311例。记录所有研究对象的病史、体格检查等临床资料及其他流行病学资料,采取聚合酶链式反应和限制性酶切片断长度多态性分析方法(PCR-RFLP)检测各组TNFSF4基因rs3850641位点A/G的基因型并统计各组的基因型频率。结果高血压病组rs3850641G等位基因型频率与对照组相比无统计学意义(P0.05)。并在校正了年龄、性别、冠心病史、糖尿病史、三酰甘油和胆固醇等传统危险因素的影响后,二者依然不存在相关性(P0.05)。结论TNFSF4基因rs3850641位点A/G多态性中G等位基因可能与中国人高血压的发病不相关。     

基于“虚气流滞”病机探讨抑郁症“炎症-线粒体损伤”恶性循环假说

抑郁症是一种危害极大的心身疾病,其发病机制和病机演变过程十分复杂,本文在王永炎院士提出的“虚气流滞”病机理论的指导下,深入剖析了抑郁症“虚气流滞”的病机特点,详细阐述了抑郁症以虚气为本、流滞为标,虚气与流滞相互裹挟、恶性循环的病机特点和演变规律,同时基于诸多研究提出抑郁症“炎症-线粒体损伤”恶性循环假说,并指出线粒体是打破恶性循环的关键治疗靶点,保护线粒体是抑郁症“补虚培元”治则的潜在生物学实质,为研究抑郁症的发病机制和防治方法提供新的思路。     

继发性单脐动脉2例及文献复习

<正>继发性单脐动脉是一种“罕见”的脐带异常,常发生于孕晚期,若不及时处理,可能会导致胎儿生长受限、胎儿窘迫、新生儿窒息,甚至不明原因的胎死宫内等不良妊娠结局,严重危害母婴健康和安全。近年来随着对继发性单脐动脉认识和警惕性不断提高,妇幼保健机构按照《孕前和孕期保健指南》进行规范的产前检查,孕妇自我保健意识提高,尤其是自感“胎动减少”及时就医,其检出率呈明显上升趋势。     

基于“虚气流滞”病机理论探讨抑郁症“虚-郁-滞”生物学实质

抑郁症的发病率与日剧增,其病因、病机、病理已成为中西医研究的热点话题。“虚气流滞”创新中医病机理论,认为元气虚衰、气血津液等流动性物质发生郁滞是抑郁症的重要发病机制,该病机强调以气虚为本,以气郁为要,以流滞为标的病理特点。本文结合临床实践经验及现代科学研究成果,以该病机假说为理论框架,提出抑郁症的生物学实质假说体系：抑郁症以突触微环境稳态失衡为核心,“气郁为要”与神经-内分泌-免疫网络失衡有关,“气虚为本”与线粒体能量代谢障碍相关,“流滞为标”与循环障碍和代谢紊乱有关,诠释了“虚-郁-滞”三者互为因果、相互裹撷,推动疾病螺旋式发展的过程,为抑郁症的分层精准诊治和机制研究提供了新的视角。
