Science: Assailants Attack China's Science Watchdog
China's self-appointed science fraud buster was assaulted yesterday afternoon in Beijing. Fang Shimin, better known by his pen name Fang Zhouzi, has used his Web site New Threads and his microblog to expose scientific misconduct, debunk crackpot medicine and pseudoscience claims, and catch cheaters who falsify resumes with fake degrees and nonexistent publications.Fang has been slammed with libel suits contesting his often-acerbic exposes. But yesterday's attack--if it was linked to his antifraud crusade--takes things to a new level...
Fang Shimin received his Ph. D. under my direction at Michigan State University. I am deeply troubled and saddened by this attack on Shimin. I wish him a rapid recovery from his injuries and a return to his work.

Fang Zhouzi Attacked near his Residence in Beijing
At 3pm of August 29, I met with two reporters from the Liaoning Satellite TV near my residence in Beijing and we went into a tea house nearby to do an interview. It was the same tea house which had been described in detail by the Chinese Entrepreneurs magazine [edit: during a previous interview]. The interview completed at around 5pm. I saw the two reporters off by a taxi. Just as I turned around and walked a couple of steps, a man suddenly came to my face and sprayed some misty material. It had acute smell, I felt dizzy and weakness in my legs and almost fainted. I immediately held my breath and ran across street. Another man came chasing me from behind with a hammer aimed at my head. I ran as fast I could, the man could not chase up to me. He then threw the hammer at me twice. The first time he was aiming at my head, it missed. I heard the sound of hammer falling into the ground and looked back. He picked up the hammer and threw it at me again. This time it hit on my waist area and blood came out there. I ran a couple of hundred meters and the guy stopped chasing. I called for emergency as soon as I reached our subdivision. Police came very fast and went about to look for eye witnesses. After interviewing with police, I went to a hospital nearby for an exam. Except for a couple of scratches near my waist, my body appeared to be fine.I first thought the misty substance used by the hooligan was pepper spray. But after discussing with medical expert, new I think it is a kind of anesthesia with ether in it. I had used ether in labs before and it smelled similar. Their plan was to have one guy make me faint and another murder me with the hammer. Maybe they had learned the lesson from a previous failed attack to reporter Fang Xuanchang. It was fortunate that I reacted quickly, ran fast, and got away.I have no personal enemies. This is obviously an attempt of someone who was exposed by me seeking revenge. They had scouted the area near my residence and waited for long and finally got this opportunity to attack. I could not speculate who was behind this. I have given the police all the hints I am aware of. This case is now being handled by the Shijingshang police station. The head of the station has called several times and appear to be diligent on the case. I hope they could find the attacker soon, as well as those who attacked Fang Xuanchang.

Beaumont Hospital's Result of Xiao Procedure Questioned in Journal of Urology
At 1 year 7 patients (78%) had a reproducible increase in bladder pressure with stimulation of the dermatome. Two patients were able to stop catheterization and all safely stopped antimuscarinics. No patient achieved complete urinary continence. The majority of subjects reported improved bowel function. One patient was continent of stool at baseline and 4 were continent at 1 year. Of the patients 89% had variable weakness of lower extremity muscle group at 1 month. One child had persistent foot drop and the remainder returned to baseline by 12 months.
The authors present the first North American experience with lumbar to sacral nerve rerouting for patients with spina bifida. The results from this study and previous animal and clinical studies by Xiao clearly demonstrate that nerve rerouting produces a somatic-autonomic or cutaneous/bladder reflex with stimulation of the lower extremity dermatome. What is also clear is that the clinical benefit of the procedure is not at all similar to previous reports.Although the authors did an excellent job of following the patients and characterizing their changes, the results are hard to validate without a control population going through the same rigorous surveillance regimen. In particular the improved bowel continence and minimal changes in bladder compliance may not be statistically significant. The fact that most patients were still on clean intermittent catheterization and none achieved complete urinary continence is troubling in light of the report of 87% success with 110 children with spina bifida presented by Xiao. One has to wonder if most of these children are not voiding volitionally or using the newly developed cutaneous reflex, and how much reinnervation has a role in this surgery. Is it possible that unilateral denervation of the S3 ventral motor nerve produced improved compliance and continence, as previously reported in numerous clinical series?I congratulate the authors for taking on this challenge. I hope this study leads to a rebirth or refocus regarding neurosurgical treatments of neuropathic bowel and bladder. I strongly agree with the authors that this procedure should remain on a research protocol only.
One of the most curious findings is the discrepancy between urodynamic data and subjective voiding. One patient exhibited a decrease in capacity and an absence of reflex arc, and yet he subjectively reported improved bladder and bowel function! I could not help but speculate that his voiding after the procedure could simply be the bladder emptying via intra-abdominal pressure generation against an open bladder neck, given his preoperative stress incontinence. Xiao reported that more than 87% of 110 patients gained sensation and continence within 1 year (reference 7 in article). In comparison, the current patients undergoing the identical procedure with the help of Xiao himself only showed a modest improvement in objective urodynamic studies and subjective reporting. Unless the innovators provide a sound argument and data for the validity of the procedure, there is a great danger of its improper and rapid adaptation by patients and the medical community at large.

USA Today: Plagiarism Shuts Down US School in China
"The college is extremely concerned with the welfare of the Chinese students involved in the program, but must note that its review revealed evidence of widespread plagiarism among other issues, at a level that ordinarily would have resulted in students' immediate dismissal from the college," Debra Albanese, Centenary's vice president for strategic advancement, said in a statement. "Despite that, in an effort to afford students every fair possibility, the college has opted to attempt to reach an amicable solution, in lieu of any such dismissal. The students were offered a choice to receive a tuition refund in exchange for a standard release in higher education or take a comprehensive exam in order to earn a degree."

A "Success" that Could be Easily Replicated
Foreign Policy: Who Tried to Kill Fang Xuanchang?
A chilling attack on a controversial science journalist in Beijing bodes poorly for scientific progress.
BY SAM GEALL | JULY 6, 2010
On the evening of June 24, Fang Xuanchang, a 37-year-old science and technology editor at China's Caijing magazine, finished work around 10 p.m. and began his walk home. Half an hour later he was nearing his apartment by Beijing's third ring road when he felt a sudden blow to his back. Fang turned to see two large men behind him brandishing steel bars.
Fang tried to run away and then shield himself as the men, ignoring his attempts to communicate with them, struck him repeatedly across his back and head. Brawny and adept in martial arts, Fang not only remained conscious, but also managed to fight back. Finally, as Fang stumbled toward a taxi, his clothes soaked in blood, the attackers left the scene.
Later that night at Beijing's Navy General Hospital, doctors sutured a 2-inch gash on the back of his head. His assailants behaved like professionals, carrying out the brutal ambush in about four minutes and showing little concern about passersby witnessing the attack. "Their goal was clear," Fang told me in a June 30 email. "It was to kill me on the spot, or stop me from reaching the hospital in time so that I would bleed to death."
Why would someone try to kill Fang Xuanchang? No one knows, or even seems to care. The attackers remain at large, despite an ongoing police investigation and Caijing's best efforts to cooperate with the police and involve the All-China Journalists Association. The attack was covered in brief in Beijing-based newspapers, including a brief editorial in a state-run newspaper arguing that journalists shouldn't be attacked. But no one in the Chinese media has gotten into the question of who would attack Fang -- and more importantly, why exactly Fang might have been attacked.
For Fang's colleagues, however, the message is clear: Reporting on controversial topics, as Fang has done, is unsafe. Journalists who are abused don't necessarily find out who has attacked them or why, but the message sent to their friends and colleagues is clear: Don't go there, or you could be next. It has a chilling effect on a wide circle of people. In the case of science journalism, the financial and political stakes are increasingly high, and the personal risks might be increasingly high as well.
Fang is one of the leading figures among China's scientific muckrakers -- a scourge of academic and government-sponsored pseudoscience and a critic of public and private quackery. For more than 10 years as a journalist, editor, and blogger on the influential (although frequently blocked) Chinese watchdog website New Threads, Fang has taken on academics listing faked awards and publishing plagiarized papers; hawkers of herbal cancer "cures," such as Wang Zhenguo, peddler of the Tian Xian herbal cancer treatment; and Chinese scientists who claim to predict earthquakes, among other targets. But paranoia and anger, even violence, mark some recent responses to Fang's work.
Several weeks ago Fang, previously science editor at China Newsweek (unrelated to the U.S. magazine Newsweek), appeared alongside a fellow rationalist, the biochemist-turned-columnist Fang Shimin (no relation, better known by his pen name Fang Zhouzi), on a Shenzhen TV debate about earthquake forecasting -- a largely discredited practice that remains an article of faith for many Chinese scientists and officials. One speaker, an official from China's national earthquake administration, a significant bureau under the State Council, spoke positively about parrots that can predict temblors and the paranormal abilities of a man who claimed he heard ringing in his ears before the quake in Yushu, in northwest China, in April. One guest on the show, Ren Zhenqiu of the Chinese Academy of Meteorological Sciences, accused the science activists of accepting U.S. money to stifle Chinese innovation. Fang Shimin claimed on his blog that after the recording, Ren Zhenqiu called him a "big Chinese traitor" and threw a punch at him.
And this is not the full extent of the threats against Fang Shimin. On July 2, Fang said on his Sina microblog that he had received a threatening phone call. "Be careful in the next few days," the voice said. "Someone is going to fix you."
Scientific ideas have a complex life in China. Today an important government slogan is the "scientific view of development," yet academic fraud is widespread. In January, the scientific journal Acta Crystallographica Section E, a peer-reviewed international journal based in Britain, announced the wholesale retraction of more than 70 papers by Chinese scientists who had falsified data. Three months later, the same publication announced the removal of another 39 articles "as a result of problems with the data sets or incorrect atom assignments." According to New Threads, 37 of these were entirely produced at Chinese universities. One Chinese-government study cited by Nature found that about one-third of more than 6,000 scientists surveyed at six top Chinese institutions said they had practiced "plagiarism, falsification or fabrication."
Critics have blamed the pressure to produce fraudulent papers on unrealistic publication targets set by bureaucrats. But for Fang Xuanchang, the problem goes deeper still, as he told me when we met in May. It represents a slide backward from the scientific spirit of the anti-imperialist May 4th Movement -- the early 20th-century uprising that championed democracy, critical thought, and innovation. Speaking after the attack, Fang described himself and his colleagues as "quixotic." "Not many people understand the work we are doing," he said. "Most Chinese people's attitudes to science are superstitious and fearful." Things might be even worse at the elite level, he said, where science is encouraged in the abstract, without a grasp of the scientific method. Regarding scientific and critical thinking, Fang added, "Chinese people need a new enlightenment."
Such issues are not only of parochial concern: Renewing China's oft-cited historical reputation for scientific innovation is a matter of urgency for the world. Last month a report from Britain's National Endowment for Science, Technology and the Arts suggested that as China enters a new phase of economic and geopolitical might, the country's potential to roll out new, low-carbon technologies becomes an increasingly important factor in global efforts to address climate change.
Harnessing scientific prowess requires promoting good academic practice, scientific education, critical thinking -- and science journalism.
