If you saw Dr. Jing-Mei ''Deb'' Chen (Ming-Na) storm off the job in a huff to care for her ailing father on Thursday night's ER, you'd better have taken a good look because it's the last you'll see of her. It's the third time the character has left the show — ''She's just a spoiled brat who can't handle the pressure,'' the actress tells TV Guide — but this time, she's leaving for good. Ming-Na calls her departure from the long-running medical drama a mutual decision. ''The producers definitely talked about running out of stuff to do with the character. I felt like it's been that way for the past year; I wondered if there's anything left. We both decided it's time to finish the character.''

Ming-Na says she has several items on her career plate. One is promoting an all-Asian boy band called At Last. Another is developing her own cooking show. ''I grew up in a Chinese restaurant and both my parents are chefs,'' she says. ''You know 'Jenny from the Block?' Now there's Ming-Na with a wok!'' As for acting, she says she'd like to do a 180 from ER and star in a sitcom. ''No more kids being thrown out the window, no more blood and gore.''
