Researchers in China and the United States have developed a new cataract(白内障)treatment with cells that has restored vision in babies in a trial and may eventually be used in adults.

The treatment- by doctors and staff members at the University of California, San Diego School of Medicine and Sichuan and Sun Yat-sen universities in China-was published in March 9 edition of the scientific journal Nature.

A cataract is a clouding of the normally clear lens(晶体)of an eye. Typical cataract operation involves the removal of the cloudy lens and the insertion of an artificial one. The new operation has been tested in animals and during a small, human trial. It resulted in fewer complications(并发症)than the current harmful operation, and in regrown lenses with superior visual function in all 12 of the baby cataract patients who received the procedure.

A congenital cataract- lens clouding that occurs at birth or shortly after- is important cause of blindness in children. In the new research, Kand Zhang, head of ophthalmic genetics at US San Diego’s Shiley Eye Institute, and his colleagues relied on the regrown potential of endogenous(同源的)stem cells.

According to Zhang, endogenous stem cells are different from other stem cells that are typically grown in a laboratory, transplanted into a patient, and can have risks of immune（免疫的）rejection, infection or cancers. Zhang told CBS News, “We invented a new operation to make a very small opening at the side of a cataractous lens bag, remove the cataract inside, allow the opening to heal, and promote potential lens stem cells to regrow an entirely new lens with vision.”

The human trial involved 12 babies under the age of 2 who were treated with the new method, while 25 babies received thee standard operation care.. The latter group experienced a higher incidence of pos- operation danger, early- onset eye high blood pressure and increased lens clouding. The scientists reported fewer complications and faster healing among the 12 babies who has the new procedure.

A conflict at work is common. If you can avoid conflict, it means you will win what you want regardless of what the other person wants. Since the potential issue has not been removed, it will simply reappear later. Here are the necessary steps to effectively get rid of conflicts at work.

★Be aware of the fact that some conflicts are unavoidable at work. On numerous occasions, conflict and disagreement are likely to happen. But when a conflict happens it's not the end of the world. On the contrary, it can be the beginning of an interesting learning process. Conflicts mean that people care enough to disagree strongly. The trick is not to allow the conflict to go on forever.

★ Deal with conflicts sooner rather than later. Solve a conflict when it starts, as it only gets worse with time going by. Conflicts at work arise not from something that was said, but from something that wasn't said! Everyone's waiting for the other to admit he's wrong and gets more unpleasant after the conflict has lasted a while. It's essential to interrupt the "waiting game" before it gets to that point.

★ Ask nicely. If somebody has done something that made you angry, or if you don't understand their viewpoint or actions, simply asking nicely about it can make a world of difference. Never assume that people do what they do to annoy or hurt you. Sometimes there's a good reason why that person does what he or she does, and a potential conflict disappear right there. Do remember to make an inquiry, not an accusation of any sort.

★ Appreciate. Praise the other part in the conflict. Tell them why it's worth it to you to solve the conflict. This can be difficult as few people find it easy to praise and appreciate a person they disagree strongly with, but it's a great way to move forward.
