Forty-six XX disorder of sex development is an uncommon medical condition observed at times during the evaluation of a man＇s fertility. The following is a case series and literature review of phenotypically normal men diagnosed with this karyotype. Our goal is to comprehend the patients＇ clinical presentation as well as their laboratory results aiming to explore options available for their management. A formal literature review through PubMed and MEDLINE databases was performed using ＂46 XX man＂ as a word search. A total of 55 patients, including those conveyed in this article were diagnosed with a 46 XX karyotype during their fertility evaluation. The patients＇ mean age _＋ s.d. was 34 ＋ 10 years and their mean height ＋ s.d. was 166 ＋ 6.5 cm. Overall, they presented with hypergonadotropic hypogonadism. Sexual dysfunction, reduced hair distribution, and gynecomastia were reported in 20% （4120）, 25.8% （8/31）, and 42% （13131） of the patients, respectively. The SRYgene was detected in 36 （83.7%） and was absent in the remaining seven （16.3%） patients. We found that a multidisciplinary approach to management is preferred in 46 XX patients. Screening for remnants of the mullerian ducts and for malignant transformation in dysgenetic gonads is imperative. Hypogonadism should be addressed, while fertility options are in vitro fertilization with donor sperm or adoption.

传统中医的起源背景与西方常规医学的发展趋势存在诸多差异。中医强调系统论,而西医注重还原论。西医进步缘自解剖、生物、生物化学、分子生物学以及现代技术,其特点是依赖实验室测试的"非正常"及明显的病症,不接受"非可视"物质及量子纠缠概念。自上世纪70年代起在美国等西方国家迅速传播与引用的中医包括针灸技术,经过数十年的发展,仍不能被西方医学界和健康保险机构正确认识或完全接受。鉴于近几年西方个别医学杂志刊登片面认识中医和盲目否定针灸疗效的文章,误导读者对传统中医的片面认识或曲解。笔者利用一组临床病例,客观分析中医针灸治疗膝痛症的特点与综合效果。该临床针灸研究共包括36个病例,分成5个年龄组。每位患者经中医疗法整体诊断后给予个体化针灸治疗方案。每次治疗前后记录症状体征,采用自我评定及数字分级评价治疗效果。纳入患者须至少完成5次治疗或全部10次治疗后总结治疗结果。36例患者中,17例患者(47.2%)的主诉膝痛症得以根治。在膝痛症患者群中,原有的其他60多种疾病也意外得到改善(98.9%)或治愈(44.2%)。说明传统中医针灸疗法治疗膝痛症疗效显著。无论传统中医还是西方常规医学,其共同目的是增进人类健康。中医针灸的客观疗效不容否认和曲解。
