目的:探讨子宫平滑肌瘤的发生与细胞凋亡的关系.方法:采用凝胶电泳技术对子宫平滑肌瘤患者的肌瘤核组织(实验组)及其周围的正常肌组织(对照组)进行DNA片段分析;采用碘化丙啶(PI)对DNA染色,流式细胞仪检测两组细胞的凋亡率,进行细胞凋亡的定量分析.结果:实验组有9例出现DNA断裂的梯形条带(9/30,30.0%),对照组有20例出现DNA梯形条带(20/30,66.7%),二者比较有明显差异;实验组凋亡率明显低于对照组.结论:子宫肌瘤的发生与细胞凋亡异常有关.     

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)

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.     

Linear parameters of normal and abnormal cava septi pellucidi: a post-mortem study

Anatomical variations in the dimensions of different brain structures have been correlated with clinical syndromes. This study on the parameters of normal and abnormal cavum septi pellucidi (CSP) can be of clinical significance. We obtained 479 brains from autopsied persons (310 males and 169 females, 377 normal or asymptomatic and 102 abnormal or symptomatic persons, aged 22-89 years) and observed that 110 brains (75 males and 35 females) had CSP. These cava were classified into two groups depending on the past medical histories of the autopsied person: 40 asymptomatic and 70 symptomatic cava. We have defined symptomatic cava as those in autopsied persons who had known past medical history of psychiatric or neurological disease. Asymptomatic cava were in autopsied persons who had no known past medical history of psychiatric or neurological disease. The CSP parameters (length, width, depth) of the symptomatic and asymptomatic groups were measured and were statistically analyzed. Analysis showed that the cava in the symptomatic group were significantly longer and wider. Discriminant function analysis was used to derive a mathematical formula to classify CSP into an asymptomatic or symptomatic group based on length and width measurements of the cavum.     

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.

TNFalpha expression in hyperplastic endometrium

PROBLEM: Tumor necrosis factor-alpha (TNFalpha) is produced by the endometrium, and it has been shown that this cytokine has cyclic variations through the menstrual cycle. METHOD OF STUDY: In this study we assessed TNFalpha, estradiol and progesterone levels in the endometrium and serum of 21 patients with recent abnormal uterine bleeding (AUB). Eleven women showed histological diagnosis of endometrial hyperplasia, and ten women showed normal endometrium. RESULTS: The TNFalpha value in the serum of patients with hyperplasia and in normal endometrium did not show significant differences (64.8 +/- 21.4 vs 77.6 +/- 14.8 pg). The amounts of TNFalpha released by hyperplastic endometrial tissue were significantly higher than in control patients (258.8 +/- 78.0 vs 140.6 +/- 79.8 pg/g; P < 0.001). Immunohistochemistry of hyperplastic endometria showed a stronger staining than normal ones. Serum E2 levels in patients with hyperplastic endometrium were 49.5 +/- 31.6 ng/mL, and in controls were 107.3 +/- 66.0 ng/mL. The levels of estradiol released by hyperplastic endometria were significantly lower than in normal endometria (152.7 +/- 60.0 vs 279.9 +/- 178.7 ng/g; P < 0.003). CONCLUSIONS: Hyperplastic endometria produce higher amounts of TNFalpha with respect to controls. These findings may explain the frequent bleeding observed in the patients with endometrial hyperplasia, since TNFalpha promotes apoptosis and endometrial shedding.     

Pregnancy following treatment of symptomatic myomas with laparoscopic bipolar coagulation of uterine vessels

BACKGROUND: Laparoscopic bipolar coagulation of uterine vessels (LBCUV) has been employed for women with symptomatic uterine myomas, but its effect on subsequent pregnancy has not been characterized. METHODS: Four-hundred and twenty-three women entered the study between March 1999 and December 2001. Of these, 142 women (33.6%) were under the age of 40 years at the time of LBCUV, 36 of whom (36/142, 25.3%) were sexually active without contraception. In a prospective study of 142 patients (<40 years old) undergoing LBCUV for symptomatic myomas, 15 women became pregnant (17 total pregnancies) and were evaluated by physical and ultrasound examinations. RESULTS: The volume of the dominant myoma was 117.4 +/- 118.4 and 36.8 +/- 56.8 cm(3) before and after LBCUV respectively. Volume of the dominant myoma after pregnancy was 46.2 +/- 76.7 cm(3) (mean +/- SD). There was a significant difference in myoma volume before and after LBCUV (P = 0.002), but no significant difference in myoma volume when comparing post-partum size with post-LBCUV size (P = 0.269). Pregnancy outcomes included seven miscarriages in the first trimester and one premature rupture of membrane (PPROM). Although the other pregnancies were regarded as uncomplicated, only two women were delivered of normal neonates as the other seven pregnancies were terminated secondary to patient request. CONCLUSIONS: The pregnancy and term pregnancy rates in sexually active women without contraception were 41.6% (15/36) and 5.6% (2/36) respectively. Because a relatively high rate (7/17, 41.2%) of early miscarriages was observed, we recommend that this procedure be employed only for women who do not desire additional children.
