Obstetric and perinatal outcome of pregnancies with term labour and meconium-stained amniotic fluid 总被引:4,自引:0,他引:4
The purpose of this study was to evaluate the meconium staining of amniotic fluid (AF) in term of fetal distress, meconium
aspiration syndrome, and perinatal morbidity and mortality. In a prospective study at Princess Badeea Teaching Hospital from
April to November 1999, women with a singleton cephalic pregnancy of completed 37–42 weeks and with no pre-defined risk factor
were recruited into the study. Study patients comprised 390 (10%) patients with meconium and 400 patients as controls but
with clear amniotic fluid. Virtually meconium staining of the amniotic fluid was significantly associated with poor neonatal
outcome in all outcomes measures assessed. Perinatal mortality increased from 2 per 1000 births with clear AF to 10 per 1000
with meconium (P<0.001). Other adverse outcomes also increased; e. g. , severe fetal acidemia, Apgar score ≤3 at 1 min and 5 min, and meconium
aspiration syndrome. Delivery by cesarean section also increased with meconium from 7–14% (P<0.001). We concluded that meconium in the amniotic fluids associated with an obstetric hazard and significantly increase
risks of adverse neonatal outcomes. Women with thin meconium in the presence of normal fetal heart rate can be safely managed
at the clinical level. Mod-thick meconium alone should alert the obstetrician to a high risk fetal condition. Continuos fetal
heart rate monitoring during labour and reassurance of fetal well-being by acid-base assessment were most significant factors
in the reduction of meconium aspiration syndrome.

Clear cell sarcoma of kidney (CCSK) is a rare, highly malignant tumor. The clinical features and treatment outcome of 12 patients with CCSK are reported. From 1982 through December 1996, 12 cases of CCSK were seen at the Regional Cancer Centre, Trivandrum, India. Patients were staged according to NWTS III recommendation. They were treated with chemotherapy containing vincristine, actinomycin, and Adriamycin and radiotherapy. The survival curve was calculated by the Kaplan-Meier method. Mass and pain in the abdomen were the presenting symptoms. Male/female ratio was 3:1. Six had stage I, 4 had stage II, and 2 had stage III disease. Of the 12, 10 were evaluable, 6 are alive, and 3 recurred in 9 evaluable. Six patients are alive free of disease 10 to 108 months after diagnosis. The overall survival and disease-free survival of the 10 patients are 64 and 56%. It would appear that combined modality treatment can cure two thirds of children with CCSK. Effective treatment needs to be developed for children who fail after first line treatment. 相似文献

Clear cell "sugar" tumor (CCST) of the lung is a very rare benign neoplasm believed to arise from epithelioid cells of perivascular differentiation. This tumor is typically diagnosed by thoracotomy. To our knowledge, only 2 case reports of CCST have been previously published: one case in which cytologic findings were subsequently confirmed histologically and ultrastructurally to be CCST, and one case of CCST diagnosed preoperatively by transbronchial core-needle biopsy. We here depict an additional case of CCST of the lung that was preoperatively diagnosed by computed tomography-guided transthoracic fine-needle aspiration biopsy and core-needle biopsy. We underscore the importance of cytologic and histologic correlation and the role of ancillary studies in differentiating this lesion from other primary or metastatic clear cell tumors of the lung. 相似文献

目的:探讨中医药降尿酸(UA)理论思路和用药规律,从临床实际用药出发为开发降UA复方或单味中药提供思路。方法:收集整理具有降UA功效报道符合纳入标准的中药复方,对其用药规律及单味药成分进行分析。结果:收集符合条件的中药复方185首,相关研究报道最多的依次为四妙散(丸)、桂枝芍药知母汤、当归拈痛汤(丸)等;共使用中药218味,使用频次最多的分别是土茯苓、薏苡仁、牛膝等;从使用较多的10味中药中找到与降UA相关或有潜在降UA可能的活性成分53种。结论:中医药降UA以清热利湿配合活血化瘀及顾护脾胃之品为主。无论是从传统中医理论还是现代药理学研究,都可以证实中医药在降UA方面有着良好的效果和广阔的前景,值得深入挖掘推广。 相似文献

Purpose
To investigate the clinical value and potential molecular mechanisms of miR-1 in clear cell renal cell carcinoma (ccRCC).Methods
We searched the Gene Expression Omnibus (GEO), ArrayExpress, several online publication databases and the Cancer Genome Atlas (TCGA). Continuous variable meta-analysis and diagnostic meta-analysis were conducted, both in Stata 14, to show the expression of miR-1 in ccRCC. Furthermore, we acquired the potential targets of miR-1 from datasets that transfected miR-1 into ccRCC cells, online prediction databases, differentially expressed genes from TCGA and literature. Subsequently bioinformatics analysis based on aforementioned selected target genes was conducted.Results
The combined effect was ?0.92 with the 95% confidence interval (CI) of ?1.08 to ?0.77 based on fixed effect model (I2?=?81.3%, P?<?0.001). No publication bias was found in our investigation. Sensitivity analysis showed that GSE47582 and 2 TCGA studies might cause heterogeneity. After eliminating them, the combined effect was ?0.47 (95%CI: ?0.78, ?0.16) with I2?=?18.3%. As for the diagnostic meta-analysis, the combined sensitivity and specificity were 0.90 (95%CI: 0.61, 0.98) and 0.63 (95%CI: 0.39, 0.82). The area under the curve (AUC) in the summarized receiver operating characteristic (SROC) curve was 0.83 (95%CI: 0.80, 0.86). No publication bias was found (P?=?0.15). We finally got 67 genes which were defined the promising target genes of miR-1 in ccRCC. The most three significant KEGG pathways based on the aforementioned genes were Complement and coagulation cascades, ECM-receptor interaction and Focal adhesion.Conclusion
The downregulation of miR-1 might play an important role in ccRCC by targeting its target genes. 相似文献849.

2016年WHO正式将透明细胞乳头状肾细胞癌作为一种肾细胞癌新类型。该肿瘤可以为散发性也可以发生于终末期肾病或Von Hippel?Lindau综合征(VHL综合征),具有相对特征性的病理组织学形态、免疫表型和分子遗传学特点,诊断时应与透明细胞肾细胞癌、乳头状肾细胞癌以及Xp11.2易位/TFE3基因融合相关性肾癌相鉴别。鉴于透明细胞乳头状肾细胞癌生物学行为相对惰性或低度恶性,因此准确诊断对指导临床治疗和判断预后具有十分重要的意义。 相似文献
