生殖道沙眼衣原体感染与不孕和自然流产的关系

采用荧光染色技术对１１０例不孕症和３２例自然流产病例的宫颈刮片标本进行检测，其中有３５例（３１．８％）不孕症和１４例（４３．７％）自然而产病人的宫颈上皮细胞内检出沙眼衣原体包涵体。与此同时，对这些阳性病例的配偶进行尿道粘膜印片检查，分别检出尿道粘膜上皮细胞内沙眼衣原体包涵体２９例（８２．６％）和１１例（７８．８％）。对照组系１３６例正常妊娠的孕妇和２００例妇女病普查的病例，分别检出衣原体包涵体５．８％和９．０５％。研究结果表明不孕和自然流产与生殖道沙眼衣原体感染有关。     

子宫内膜异位症并发不孕患者子宫内膜超微结构观察

目的：探讨子宫内膜异位症（EM）并发不孕患者围着床期子宫内膜的超微结构。方法：选择轻度子宫内膜异位症并不孕患者10例为研究组，已生育妇女7例作为对照组，选择在月经周期第19－22天刮取少量子宫内膜，进行扫描及透射电镜观察。结果：异位症患者围着床期子宫内膜出现超微结构改变，内膜表面腺体开口数少，纤毛再生不全，分泌细胞表面微绒毛极少，子宫内膜着床窗的形态学标记－细胞表面胞饮小泡减少 或缺失；胞质肿胀疏松，有的细胞出现核固醇，结论：异位症患者围着床期在位子宫内膜出现超微结构改变，细胞出现轻度变性，可能是其不孕的原因之一。     

棉酚服用者睾丸活检的形态及定量组织学研究

对48例服棉酚者睾丸活检组织进行形态学及定量组织学研究。光镜下可见紊乱型、脱落型和严重障碍型三种精子发生障碍。电镜下可见除精子细胞、精母细胞改变外,精原细胞及支持细胞结构也有明显改变。自动图象分析结果表明:三种类型生精障碍曲细精管横截面平均面积和平均细胞总面积与正常对照相比,存在非常显著差异:三种类型生精障碍之间的曲细精管横截面平均面积和平均细胞总面积也有非常显著差异。     

Musical obsession or pseudohallucination: Electrophysiological standpoint

Reported herein is a case of obsessive–compulsive disorder with persistent and distressing musical obsessions along with other symptoms. Advanced source analysis of electroencephalographic data indicated high spectral power over the bifrontal region. The musical symptoms were resistant to pharmacotherapy but there was some reduction in frequency and duration of musical obsessions with thought-stopping technique.     

Bulbar and spinal muscular atrophy (Kennedy's disease): a review

Bulbar and spinal muscular atrophy (BSMA) is an adult-onset, X-linked recessive trinucleotide, polyglutamine disorder, caused by expansion of a polymorphic CAG tandem-repeat in exon 1 of the androgen-receptor (AR) gene on chromosome Xq11-12. Pathogenetically, mutated AR accumulates in nuclei and cytoplasm of motor neurons, resulting in their degeneration and loss. Phenotypically, patients present with amyotrophic, proximal or distal weakness and wasting of the facial, bulbar and limb muscles, occasionally sensory disturbances, and endocrinologic disturbances, such as androgen resistance, gynecomastia, elevated testosterone or progesterone, and reduced fertility. There may be mild hyper-CK-emia, abnormal motor and sensory nerve conduction studies, and neuropathic and myopathic alterations on muscle biopsy. The golden standard for diagnosing BSMA is genetic analysis, demonstrating a CAG-repeat number >40. No causal therapy is available, but symptomatic therapy should be provided for tremor, endocrinologic abnormalities, sensory disturbances, or muscle cramps. The course is slowly progressive, the ability to walk lost only late in life, only few patients require ventilatory support, and life expectancy only slightly reduced.     

The Effect of Reduced Somatosensation on Standing Balance: A Systematic Review

The objective of this review is to identify and review publications describing the impact of reduced somatosensation on balance. Based on knowledge of the association between specific somatosensory loss and deterioration of balance, conclusions can be made about role of somatosensation in standing balance.A systematic literature review is presented in which publications from the years 1993 through 2007 were searched in Medline and Embase. Medical Subject Headings (MESH) terms and free text words (related to balance, somatosensory loss, and lower limb) were used to perform the searches. Fifteen articles were selected for detailed review based on predetermined inclusion criteria, and three of the included articles described the effect of experimentally reduced somatosensation on balance in healthy subjects. Ten of the articles described balance in diabetic neuropathy (DN). The last two included articles described balance in Charcot-Marie-Tooth (CMT) disease type 1A (CMT1A) or type 2 (CMT2).The literature indicates that the tactile sensation is reduced in DN, CMT1A, and CMT2 and when the plantar surface of the feet was hypothermically anesthetized. Joint motion sensation seems to be impaired in patients with DN, and passive joint position sensation appears to be reduced in healthy subjects with anesthesia of ankle and foot from prolonged ischemia. This reduced somatosensation seems to have a negative effect on balance in patients with DN and CMT2; however, this appeared not to be the case in patients with CMT1A and in healthy subjects.     

A schema-focused approach to group psychotherapy for outpatients with borderline personality disorder: A randomized controlled trial

This study tests the effectiveness of adding an eight-month, thirty-session schema-focused therapy (SFT) group to treatment-as-usual (TAU) individual psychotherapy for borderline personality disorder (BPD). Patients (N = 32) were randomly assigned to SFT-TAU and TAU alone. Dropout was 0% SFT, 25% TAU. Significant reductions in BPD symptoms and global severity of psychiatric symptoms, and improved global functioning with large treatment effect sizes were found in the SFT-TAU group. At the end of treatment, 94% of SFT-TAU compared to 16% of TAU no longer met BPD diagnosis criteria (p < .001). This study supports group SFT as an effective treatment for BPD that leads to recovery and improved overall functioning.     

学习障碍患儿血清BDNF水平的研究

目的探讨学习障碍血清脑源性神经营养因子(BDNF)水平的变化,及其与学习障碍病理基础的关系。方法患者组为22例未治疗过且不共患其他疾病的学习障碍患儿,对照组为16例年龄性别匹配正常儿童,以瑞文标准推理测验(SPM)测定智商,BDNF采用酶联夹心免疫吸附法检测。结果LD患者血清BDNF浓度为:平均(4.603±3.620)ng/ml高于对照组(1.843±0.728)ng/ml(t=3.326,P=0.003<0.01)。边缘智商组(4.523±4.618)ng/ml,与正常对照组比较差异有非常显著性(P=0.008<0.01)。结论学习障碍患儿血清BDNF浓度高于正常儿童,边缘智商者升高更明显。     

Chromosomal Rearrangements in Three Infertile Men

Summary:  Three chromosomal rearrangements: a balanced reciprocal translocation, t(14;10) (q22;q13), a Y-autosome translocation, t(Y;16) (q11;p13) and a deleted Y chromosome, Yq- were detected among 100 infertile men. The autosomal translocation, associated with oligozoospermia was found to be familial with various effects on the female carriers and the proband's father. The patients with the chromosome Y abberations were found to be azoospermic and might have lost the genes necessary for normal sperma-togenesis.
Zusammenfassung:  Unter 100 infertilen Männern wurden drei Chromosomenneuan-ordnungen entdeckt: eine balancierte reziproke Translokation, t(14;10) (q22;q13), eine Y-autosome Translokation, t(Y;16) (q11;p13) und eine Deletion des Y-Chromosoms, Yq-. Die autosomale Translokation bei Oligozoospermie zeigte sich familiär mit verschiedenen Auswirkungen bei den weiblichen Überträgern und dem Vater des Probanden. Die Patien-ten mit chromosomalen Y-Aberrational wiesen eine Azoospermie auf und scheinen die zur normalen Spermatogenese notwendigen Gene verloren zu haben.
