宫腹腔镜联合手术诊治不孕症150例分析

目的:探讨宫腹腔镜联合手术在诊治不孕症中的应用。方法:对150例不孕症患者行宫腹腔镜联合手术,对不孕症病因进行诊断,同时行治疗。结果:盆腔粘连和输卵管阻塞是不孕症的主要原因。子宫内膜息肉和正常盆腔占次要比例。子宫内膜异位症和多囊卵巢也是主要病因。150例同时行宫腹腔镜输卵管通液和各种疾病的治疗。联合手术后妊娠率为48.8%。结论:腹腔镜联合手术,在一次麻醉下,可以对不孕的原因全面评价和明确诊断,在诊断同时进行治疗,对不孕症的诊断和治疗有重大的意义,值得推广。     

Acute respiratory distress during Caesarean section under spinal anaesthesia A probable case of anaphylactoid reaction to Syntocinon

A case of life-threatening respiratory distress during a Caesarean section under spinal anaesthesia is reported. Possible causes of the event including anaphylactoid reactions and the methods of their diagnosis are discussed. The most likely cause of the episode was felt to be an anaphylactoid reaction to Syntocinon.     

The Rigiflex TTS: A New Method to Dilate Benign Esophageal Stenosis

Abstract: This paper dicusses the use of esophageal dilatation with a Rigiflex TTS balloon. This method was used 45 times on 11 patients affected by anastomotic or a severe grade peptic esophageal stenosis. Fluoroscopic guidance was used in 36 procedures (80%) without effecting the mean duration of the treatment (12 minutes). The results were considered satisfactory when these goals had been achieved: a) dilatation of the stenosis over 15 mm; b) a dysphagia free-time of more than 6 months. A satisfactory result was achieved in 10 patients (90.9%), without deaths and major complications. 5 patients received 1 dilatation and the other 5 needed, 3-3-4-7–11 procedures respectively to obtain a satisfactory result. On these basis we consider that its great efficacy, security and tolerability depend on the following characteristics of the Rigiflex TTS balloon: 1) “radial” dilatation; 2) the possibility of introducing the balloon through the operative channel of the fiberscope; 3) direct visualization of the stenosis during dilatation. The following disadvantages with this method are: the absence of a tactile sensation of dilatation and the elevated cost of the instrument. We conclude that the Rigiflex TTS balloon is an important alternative to guide-wire techniques, especially for the treatment of severe esophageal strictures.     

妊娠肝内胆汁淤积症患者血清一氧化氮和内皮素的变化及意义

目的：探讨妊娠肝内胆汁淤积症（ICP）患者外周静脉血清、新生儿脐静脉血清中一氧化氮（NO）、内皮素（ET）、丙二醛（MDA）和超氧化物歧化酶（SOD）含量的变化及在ICP发病中的作用。方法：以ICP组28例为研究组，测定其外周静脉血清及新生儿脐静脉血清中的NO、ET、MDA和SOD，以年龄相近的24例正常孕妇作为对照组。结果：ICP患者的MDA和ET含量较正常晚期妊娠显著增高（P＜0．01），ICP患者的NO和SOD含量与对照组相比无显著性差异（P＞0．05）。母血清中NO、ET、MDA含量均较新生儿脐静脉血清中的含量高，差异有显著性（P＜0．01）。结论：妊娠期体内氧化和抗氧化失衡及ET水平的增高可能与ICP的发生、发展有关。     

Functional and humor disorders as health indicators in adolescence

In 1988, an epidemiological study concerning self-perceived health problems was carried out on a sample of 3,288 adolescents aged 11 to 19. Eight functional and depressive symptoms (FDS) were investigated. Among girls, FDS (especially sleep disorders, headaches, feelings of nervousness or depression) appeared to be common and increased between ages 11 and 19. Among boys, FDS were less common and did not increase during adolescence. Thus, at age 18, sex differences were clearly established. Results suggest a link between FDS and intrafamilial relationships, especially the aggressive attitude or the rejection of the parents and their lack of interest. For the 11-15 age group, FDS are related to school behavior, but not to school performance.     

Anulus fibrosus in bulging intervertebral disks

In this investigation the association of radial tears of the anulus fibrosus and bulging of the intervertebral disk was studied. An index of disk bulging was measured in sagittal anatomic sections in 149 lumbar disks from 31 cadavers. The indexes of disk bulging were correlated with stages of disk development and the presence of an annular tear. The largest disk-bulging indexes were always associated with radial tears of the anulus. Eighty-four percent of the disks with radial tears had disk-bulging indexes greater than 2.5 mm. Most normal adult disks had an index of less than 2.5 mm. The results challenge the concept that the anulus fibrosus is intact in bulging disks, although ruptured in herniated disks.     

Aerobiology of the Colorado Rockies: pollen count comparisons between Vail and Denver, Colorado.

Pollen patterns were compared between Vail, CO (8,200 feet elevation), Aspen, CO (7,900 feet) and Denver, CO (5,280 feet) from 1984 through 1988. Counts were obtained at all sites with a volumetric intermittent cycling rotating impaction sampler. Aspen and Denver were compared in 1984, and Vail and Denver from 1985 through 1988. While counts were generally lower in the mountain sites than Denver, certain pollens, especially trees, were quite high. Ragweed was essentially absent from Aspen and Vail, and chenopod-amaranth counts were very low. Cedar, pine, and aspen frequently pollinated despite active snowfall.
