肖传国和方舟子就肖氏手术(“肖氏手术”)试验项目在美国的境遇各执一词。到底真相如何?由于肖方是宿敌,双方观点皆不可采信。其真相或可从文献研读做点判断。由于涉及非常专门知识,先从英文词汇开始,然后呈现双方证据,再提一些疑惑,希望有人解惑,以期得出结论。

疑惑:

1、双方的依据是否真实?

2、两个项目的关系是什么?

3、方舟子提到的项目为什么是“Withdrawn” 而不像下列图中有的的项目是“Completed”?



4、科学原理是谁首先提出?(将来如果获诺贝尔奖,他是首位获奖者)

5、科学原理转化为实用技术还需要做很多实验研究。这些研究的成果的知识产权归谁?归美国的话,肖教授是不是不能无偿地在中国应用?

6、从项目名称上看,不涉及膀胱(Bladder)的项目是处于“ongoing”,而涉及膀胱(Bladder)的项目是处于“withdrawn”,是不是这样?

美国国家卫生院称肖氏手术的试验方案是不可接受的

  作者:新语丝志愿者

  三年前,美国卫生与人类服务部(HHS)人类研究保护办公室(OHRP)回复新语丝志愿者代表程鹗,该办公室已开始调查评估新语丝志愿者所举报的有关“肖氏手术”事项(见《美国开始调查肖氏手术临床试验,停止招募病人参与临床研究(XYS20101022)》,并称待调查评估结束后将通知结果。近日,该办公室致函程鹗:美国国家卫生院(NIH)决定,经过对试验方案的长时间评估,根据外部专家组的意见建议,招募患者参加神经改道手术(即“肖氏手术”)的试验方案被认定为不可接受。对此前已由民间资助做过肖氏手术的儿童,研究者将研究其长期影响。  

该NIH资助的多中心临床试验项目,由William Beaumont医院牵头,原计划由多家医院参加,原定2009年底启动。2010年6月,Duke大学Wiener医生在学术会议中透露,NIH担心手术可能伤害患者而搁置该项目。2010年10月,人类研究保护办公室接受新语丝志愿者举报后回复,该试验已停止招募患者。2010年11月,试验主持人Peters医生向《科学》确认,NIH已成立监督委员会复核该试验,该医院将提交修改过的试验方案。2011年8月,该项目临床试验信息表明,参与该项目的亚特兰大Emory大学已退出,“多中心临床试验”参与者仅剩Beaumont医院。2012年3月,Peters医生在学术会议中透露,该试验已搁置两年,他们一直与出资机构密切合作,希望尽快解除搁置。2012年3月,该项目临床试验信息中的试验目标被删改,观察指标降低。2013年8月,该项目临床试验信息注明,“本研究已于注册患者前撤销”,试验终止原因是“研究者提供的试验方案未获NIDDK【NIH下属出资机构】批准”。  

关于该试验项目及其他肖氏手术试验项目近年来的状况,请参考《肖氏手术国外临床试验情况》http://xysblogs.org/yush/archives/9774  

我们将向有关机构索取该试验的详细资料,特别是该项目的复核评估文件及专家组的意见建议。  

附录:OHRP邮件翻译及原文  

亲爱的程先生:  

关于你所关注的William Beaumont医院的“肖氏神经改道手术”,人类研究保护办公室(OHRP)已接到国家卫生研究院国立糖尿病、消化道和肾脏疾病研究所(NIDDK)的通知:经过长时间评估主持人Kenneth Peters博士所提出的试验方案,以及外部专家组(EEP)成员们提出的意见建议,该研究所决定,招募患者参加该外科手术的试验方案被认定为不可接受。当然,对于此前由非政府机构资助的研究中已做过神经改道手术的儿童,研究者们将研究神经改道的更长期影响。  

OHRP认为这些措施得当。我们预计不再参与此事。  

OHRP感谢你对人类研究受试者保护的关注。如果你有任何疑问,或希望提供更多信息,请尽管随时与我联系,  

真诚的,

Subject: "Xiao Procedure"  


Dear Mr. Cheng:  

Regarding your concerns about the "Xiao nerve-rerouting procedure" at William Beaumont Hospital, the Office for Human Research Protections (OHRP) has been informed by the National Institutes of Health, National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) that after lengthy evaluations of the protocols proposed by Dr. Kenneth Peters, the PI, and the advice NIDDK received from the members of the External Expert Panel (EEP), the Institute decided that the protocol submitted to enroll patients for this surgical procedure was not found acceptable. However, the investigators will study the longer term effects of nerve rerouting in children who had the nerve rerouting operation performed in a previously conducted study not supported by the government.  

OHRP finds these actions to be appropriate.  We anticipate no further involvement in the matter.  

OHRP appreciates your concern about the protection of human research subjects.  Please do not hesitate to contact me at any time should you have any questions or wish to provide additional information.  

Sincerely,  

Kristina C. Borror, Ph.D.

Detailed Description:

Spinal cord injury (SCI) and spina bifida is a source of irreversible injury to the spinal cord often resulting in paralysis and loss of sensation below the waist. The inability to urinate normally is a consequence of both conditions (neurogenic voiding dysfunction). In spina bifida and spinal cord injury, the nerve that controls the bladder and sphincter (the muscle that squeezes the bladder neck to prevent leaking) may no longer work properly resulting in patients who cannot urinate or are constantly wet.


Most patients will maintain high pressures in their bladder and these elevated pressures will eventually take its toll by causing recurrent urinary tract infections, backup of urine to the kidneys, and marked dilatation of possible further damage to the kidneys. Many patients eventually suffer from irreversible renal (kidney) damage, where dialysis or kidney transplant is the only way to sustain life.


Spinal bifida (present at birth) and SCI (occurs most often early in the fourth decade of life) predominately affect young individuals and longevity and quality of life may be greatly reduced by the presence of bladder, bowel, and sexual dysfunction. In the recent past, medications and catheters were the only way to help cord injured patients empty their bladders. Although clean intermittent catheterization (CIC) provides good maintenance results, medications can help conserve low bladder pressures, and antibiotics sustain an infection free urinary tract, these are difficult bladder management programs to uphold. They are expensive, time consuming, and outcomes are inconsistent.


A new surgical procedure has potential for treatment of spinal cord injuries/ spinal bifida. Recently, Dr. Chuan-Guo Xiao from China developed a surgical procedure of rewiring the nerves in the spinal cord to gain better control of urination and avoid complications of neurogenic bladder. The procedure reconnects live wires (nerves) to dead wires.

Study Start Date:January 2013

Study Completion Date:January 2013

Primary Completion Date:January 2013 (Final data collection date for primary outcome measure)

Intervention Details:

Procedure: Nerve Rerouting

All subjects will receive the unilateral nerve rerouting procedure.


Detailed Description:

Spina Bifida (a congenital defect of the spinal cord), causes nerve damage and a loss of sensation and muscle function below the waist resulting in bowel and bladder dysfunction. Patients cannot urinate or are constantly wet, and this continues throughout life causing major quality of life and health problems. Clean intermittent catheterization (draining urine from the bladder with a tube) is usually needed to empty the bladder properly. Medications are routinely required to alleviate high urinary tract pressures that can cause irreversible kidney damage, where dialysis or kidney transplant is the only way to sustain life.


A Chinese urologist developed a novel procedure to connect a functioning, healthy lumbar spinal nerve to the sacral nerve that controls the bladder. Hundreds of these procedures have been done in China. The end result is the creation of a new reflex where the bladder can be emptied by scratching or stimulating the skin (over the hip or thigh) supplied by that spinal nerve root. The Chinese physician had reported that of 92 SCI patients, 88% regained bladder control within one year after the nerve rerouting surgery and in 110 children with spina bifida, the reported success was 87% at one year. However, in China rigorous follow up is challenging, therefore much is still unknown about how the nerves regenerate post surgery, complications and results occurring in the first year in particular, and the potential role that central nervous system remodeling may play in achieving successful outcomes. Beaumont urologists were the first in the US to perform this surgery on children with spina bifida. Our preliminary data are very promising, and in 9 subjects at 12 months post procedure, 7/9 subjects could void either voluntarily or by stimulating the new reflex mechanism.


This current project aims to expand upon our pilot experience to conduct a larger and more rigorous study to establish the safety and effectiveness of the proposed somatic-autonomic reflex pathway procedure in gaining bladder and bowel control in patients with spina bifida. We will also collaborate with and train investigators at another site(s) to determine the training needed to achieve similar safety and effectiveness outcomes, and evaluate possible methods to stimulate the new reflex to improve bladder emptying. Achieving the aims outlined in this multicenter proposal will help firmly establish the procedure as safe and effective, and revolutionize the treatment of bladder and bowel dysfunction in patients with spina bifida in the US.
