生长抑素治疗食管胃底静脉曲张破裂出血的临床研究

目的 探讨生长抑素治疗食管胃底静脉曲张破裂出血的临床效果。方法 应用奥曲肽治疗食管胃底静脉曲张破裂出血患者41例,并与垂体后叶素治疗的32例及三腔管治疗的25例进行对照。观察3组平均止血时间、24h止血率以及治疗前后门静脉主干直径、血流速度、血流量的变化。结果 奥曲肽治疗组、垂体后叶素治疗组、三腔管治疗组平均止血时间分别为194.27±28.88min、358.11±151.43min、134.71±32.12min,24h止血率分别为63.41％、37.50％、72％。奥曲肽治疗组止血率显著高于垂体后叶素治疗组(P<0.01)。奥曲肽治疗前后门静脉内径分别为10.86±0.41mm、13.84±0.35mm,二者有显著差异。奥曲肽治疗后其门静脉血流速度,血流量与治疗前相比较也有显著差异(P<0.01,P<0.05)。结论 奥曲肽能使门脉内径相对缩小、血流量减少和血流速度加快,从而使门脉压力降低达到止血的目的。     

Congenital cervical atresia: Report of seven cases and review of the literature

OBJECTIVE: Our aim was to evaluate the clinical course and management of congenital cervical atresia. STUDY DESIGN: This retrospective analysis included 7 patients referred to our clinic and a review of the medical literature. RESULTS: Including this case series, 58 cases of congenital cervical atresia have been reported in the literature. Forty-eight percent of patients had isolated congenital cervical atresia with a normal vagina whereas the remainder had either complete or partial vaginal atresia (“shortened blind vaginal pouches”). Surgical management has included abdominal hysterectomy or uterovaginal cannulation with or without vaginoplasty. In 59% of patients who underwent uterovaginal canalization procedures (23/39), normal menstrual bleeding was achieved. Four of these patients subsequently became pregnant and were delivered at term. CONCLUSION: Surgical canalization in selected patients with congenital cervical atresia can be successfully performed to provide patients an opportunity for conservative management, resulting in normal menstrual bleeding, resolution of cyclic pelvic pain, and some potential (albeit limited) for fertility.(Am J Obstet Gynecol 1997;177:25)     

冲洗液温度对前列腺切除术后出血的影响

目的 研究冲洗液温度对前列腺切除术后出血的影响。方法 耻骨上前列腺切除术患者80例,年龄60～82(平均67.4±10.3)岁,随机分为两组各40例。A组采用20℃的冲洗液冲洗膀胱,B组采用37℃的冲洗膀胱。两组所有患者均于膀胱冲洗前抽静脉血,分别测定其在20℃和37℃状态下的激活部分凝血活酶时间(APTT)、凝血酶原时间(PT)、凝血酶时间(TT)。同时比较两组术后出血量、冲洗总液量、血尿时间、寒冷反应及膀胱痉挛发生率,结果 检测80例患者血APTT,PT,TT均存在显著差异(P<0.001;冲洗总液量分别是(47883±±8953)ml和(19741±5490)mL,P<0.001;尿液转清时间分别是(47.5±16.9)h和(19.8±5.7)h,P相似文献   

Rockall危险性积分在急性上消化道出血中的应用

目的：探讨Rockall危险性积分在急性上消化道出血中的应用。方法：262例按Rockall危险性积分进行评分，并分为低危组（0～3）、中危组（4～7）、高危组（≥8）。结果：高危组与中危组相比再出血率差异无统计学意义（P〉0．05）。高危组与中危组相比死亡率明显升高（P〈0．05）。结论：Rockall危险性积分对急性上消化道出血患者的病情评估具有重要的意义。     

Surgery in Jehovah’s Witnesses

This is a retrospective study of the outcome of surgical procedures in patients who were Jehovah's Witnesses. Over a 75-month period, 58 Jehovah's Witness patients had 78 surgical procedures at the Vancouver General Hospital. Three patients had preexisting anaemia of less than 100 g.L-1 haemoglobin. Postoperative haemoglobin concentration decreased below 50 g.L-1 in three patients. One patient had a postoperative haemoglobin of 34 g.L-1 (haematocrit 10.1 per cent) and survived. One patient died from uncontrollable postoperative haemorrhage. Perioperative morbidity was not uncommon, including significant hypotension (eight cases), cardiac arrhythmias (six), myocardial ischaemia (three), excessive bleeding (four), postoperative nausea or syncope (four), and wound or urinary tract infection (four).     

子宫阔韧带内静脉的解剖学研究及其临床意义

子宫底和体上部的静脉汇集于子宫角处浅出,应称子宫上静脉。该静脉续为卵巢静脉。子宫上静脉1条者占30%,2条者占56.7%,3条者占13.3%。子宫上静脉与输卵管峡部中点相对处的口径是3.7±0.2mm,卵巢丛与子宫上静脉汇合后的口径为5.0±0.4mm。输卵管峡部中点与子宫上静脉的间距为6.3±0.6mm。在输卵管系膜中见有输卵管静脉汇入子宫上静脉。本文研究结果认为盆腔静脉淤血症的发生,与结扎手术中损伤子宫上静脉和输卵管静脉有关。     

Fetal cervical hyperextension in arthrogryposis

Perhaps the most dramatic position of a newborn after delivery is when there is hyperextension of the neck and spine. It will have been presented in utero and today, almost always, such babies will have been delivered by C‐section. The associated anomalies are variable. The process(es) that can lead to cervical hyperextension is/are largely unknown. The outcome is variable from lethal to completely resolve. Individuals with arthrogryposis and in particular with Amyoplasia appear to have an increased frequency of neck, cervical, and spine hyperextension at birth. We present here 41 cases of arthrogryposis (mainly Amyoplasia) with fetal cervical hyperextension. The outlook is surprisingly good if spinal cord trauma does not occur. Ultrasound late in pregnancy when arthrogryposis is recognized prenatally should determine whether cervical hyperextension has developed, so that appropriate preventive measures can be taken.     

Changes in the withdrawal bleeding pattern and endometrial histology during 17β-estradiol —dydrogesterone therapy in postmenopausal women: a 2 year prospective study

Objective: To describe changes in the withdrawal bleeding pattern and endometrial histology during a sequential 17β-estradiol —dydrogesterone regimen in postmenopausal women. Design: Open-label, non-comparative, prospective study. Setting: Gynecological outpatient department of a university hospital. Patients: Twenty-seven healthy nonhysterectomized postmenopausal women. Interventions: Continuous micronized 17β-estradiol supplementation, 2 mg daily, and cyclic administration of dydrogesterone, 10 mg daily for the first half of each 28 day treatment cycle. Main Outcome Measures: Changes in the characteristics of the withdrawal bleeding pattern and the endometrial biopsy histology during 2 years of treatment. Results: The initial withdrawal bleeding was comparable to normal menstruation with respect to amount and duration. During the 2 years of treatment the bleeding showed a significant tendency to become shorter with less blood loss. This was mainly the result of the decrease (P < 0.001) in the number of days per cycle with bleeding grade II (normal menstruation). None of the women developed endometrial hyperplasia, and in almost all women the given hormone replacement therapy regimen induced secretory or atrophic changes of the endometrium. Conclusions: This sequential 17β-estradiol —dydrogesterone regimen can be regarded as safe with respect to the prevention of endometrial disease and appeared to foster patient compliance.     

A functionally active complement system is present in uterine secretion of the mouse prior to implantation.

Sephadex beads were placed carefully in the uterus on days 2 and 3 and left for 6 to 8 h to absorb uterine secretion. The beads were then removed with volatile silicon oil and mounted on small pieces of nitrocellulose paper. Immuno-staining of these bead blots showed they contained the complement components C1q, C3, C4, and C5. We demonstrated that complement component C3 in the uterine secretion could be activated and deposited on model immune complexes, and also that antibody-coated erythrocytes were lysed in utero, that is, a membrane attack complex was produced. Thus, the mouse uterine secretion at the preimplantation stage contains a functionally active complement system.
