Morphological analyses and a novel de novo DLX3 mutation associated with tricho–dento–osseous syndrome in a Chinese family

Tricho–dento–osseous (TDO) syndrome, an autosomal‐dominant disorder, affects the morphological appearance of the tooth enamel, hair, and bone. Previous studies have confirmed that mutations in the DLX3 gene are responsible for TDO. In this study, we describe a Chinese patient with the typical traits of TDO – kinky hair, enamel hypoplasia, skull and jaw bones thickening, and sclerosis. Unfortunately, as a result of excessive attrition, we were unable to assess taurodontism. Examination of the tooth ground section showed a thin layer of enamel with no rods on the patient's tooth and abnormalities in Tomes' granular layer and the dentinal tubules. Scanning electron microscopy and energy‐dispersive X‐ray spectroscopy of the tooth enamel showed significant differences between the patient and the control individuals. A hair sample from the patient observed under a laser‐scanning microscope showed longitudinal grooves in the hair shaft. Dual‐energy X‐ray absorptiometry measurement showed that the bone mineral density values of the patient's bones was much higher than normal. Finally, genetic analysis revealed a novel de novo missense mutation c.533A>G (p.Q178R) in the conserved homeodomain of the DLX3 gene. This DLX3 mutation is the sixth causative mutation for TDO to be identified so far.

经导管肾动脉化疗栓塞联合射频消融术治疗肾癌的疗效分析

目的评价TACE联合射频消融术(RFA)治疗肾癌的疗效。方法回顾性分析我中心收治的23例肾癌患者资料。全部患者均首先行肾TACE治疗,并在3~4周后在超声及CT的联合引导下行RFA术。评价患者术前术后的卡氏功能状态评分(KPS评分)及肾功能变化情况,同时在随访期内定期对患者行腹部超声、CT/MR增强扫描评价其疗效。结果至随访终止,全部23例患者中生存21例(21/23,91.30%),死亡2例(2/23,8.70%)。全部患者在术前和随访期结束时的KPS评分及血肌酐水平差异无统计学意义(P均0.05)。至随访结束,23例患者肾内病灶的治疗效果为完全缓解16例、部分缓解5例、进展2例。结论 TACE联合RFA治疗肾癌创伤小、疗效确切、围术期并发症少,是一种较为安全有效的方法。     

Molecular Mechanisms of Vacuum Therapy in Penile Rehabilitation: A Novel Animal Study

Background

Penile rehabilitation (PR) is widely applied after radical prostatectomy. Vacuum erectile device (VED) therapy is the one of three PR methods used in the clinical setting that improve erectile function (EF) and is the only PR method which may preserve penile length. However, its unknown mechanism hampered doctors’ recommendations and patients’ compliance.

Objectives

To assess the effects of VED therapy on erectile dysfunction (ED) in a rat model of bilateral cavernous nerve crush (BCNC) and to investigate the molecular mechanism of VED in postprostatectomy ED.

Design, setting, and participants

This was an experimental study using Sprague-Dawley rats in three groups: sham, BCNC, and BCNC plus VED.

Intervention

Intervention included BCNC, electrical stimulation of the cavernous nerve (CNS), and VED therapy.

Measurements

At the end of a 4-wk period, CNS was used to assess EF by maximum intracavernosal pressure (ICP)/mean arterial pressure (MAP) ratio and duration (area under the curve [AUC]). For the structural analyses, whole rat penis was harvested. Terminal deoxynucleotidyl transferase biotin-dUTP nick end labeling assay was used for the assessment of apoptotic indices (AI). Immunohistochemistry was performed for endothelial nitric oxide synthase (eNOS), α-smooth muscle actin (ASMA), transforming growth factor beta 1 (TGF-β1), and hypoxia inducible factor-1α (HIF-1α). Staining for Masson's trichrome was utilized to calculate the smooth muscle/collagen ratios.

Results and limitations

EF was improved with VED therapy measured by ICP/MAP ratios and AUC. VED therapy reduced HIF-1α expression and AI significantly compared with control. Animals exposed to VED therapy had decreased TGF-β1 expression, increased smooth muscle/collagen ratios, and preserved ASMA and eNOS expression.

Conclusions

To our knowledge, this is the first scientific study to suggest that VED therapy in the BCNC rat model preserves EF through antihypoxic, antiapoptotic, and antifibrotic mechanisms.     

强制婚检政策取消前后我国出生缺陷发生率变动的meta分析

目的:了解2003年强制婚检政策取消前后我国出生缺陷发生率的变动情况.方法:整理文献,将2002年和2003年的出生缺陷数和围产儿数分别合并后得出的出生缺陷发生率作为对照组,与2005年的相应出生缺陷发生率利用meta方法进行分析比较.结果:取消强制婚检后2005年出生缺陷发生率是取消前2002年和2003年合并出生缺陷发生率的1.11倍(D+L pooled RR=1.11,95％ CI=1.04 ～1.18),差异具有统计学意义.结论:取消强制婚检后,我国出生缺陷发生率有所上升,取消婚检与这一趋势可能存在一定关系.提倡婚前检查,同时加强孕前生殖健康保健服务及孕检对改善我国出生缺陷发生有帮助.
