GUANGZHOU , Jan. 28 (Xinhua) -- As surgeons were busy boring a hole in his skull, a 57-year-old man plucked the delicate strains of "Romance De Amor" from his guitar.

It's not a fictional scenario. It happened earlier this week in an operating theater in the southern city of Shenzhen, as neurologists operated on a patient suffering from focal dystonia.

For the past days, images of Li, with his head immobilized by an elaborate arrangement of medical hardware, playing the guitar have been circulated on social media.

While some doubted publicity purposes of the medical team , Cai Xiaodong, chief neurosurgeon at Shenzhen No.2 People's Hospital, insisted that it was a necessary step of deep brain stimulation (DBS), one of the most advanced neurological treatments.

The new technique, combining neurology, neurosurgery and electrical engineering , allows doctors to implant tiny electrodes in patients' brains to affect abnormal cells, chemicals or impulses behind a number of neurological conditions such as tremors, dementia and, in Li's case, dystonia.

Once a classical guitarist, Li developed dystonia in his right hand two decades ago. The condition , sometimes known as "musician's cramp," has prevented him from playing guitar ever since, despite years of medication.

Cai decided that DBS was appropriate for Li, as it had little chance of causing paralysis, a common side-effect of brain surgery.

After Cai explained to Li how DBS works, the patient agreed to have the procedure.

Once the electrodes are in place , they deliver a weak but constant current that will reduce or eliminate his symptoms. The most challenging part of DBS is to locate precise spot in the brain. That's why patients must remain conscious during the procedure.

"It is essential for doctors to identify the exact spot where the electrodes will do the most good," Cai said. "We need to track the effects of the surgery in real time."

During the operation, Cai required Li to play the guitar and from time to time to describe what he was feeling.

As shown in a short video clip, Li was able to play immediately after four hours of surgery.

Li's right hand has recovered 80 percent of its function, and the remaining 20 percent might work too after a rehabilitation program.

Cai said DBS has been widely used to treat Parkinson's disease, but he claimed it was the first time the technique had been used to treat hand dystonia in China.

Despite Cai's enthusiasm , DBS is still far from being an instant therapy. The electrodes are powered by battery packs sewn into Li's left chest, and it requires follow-up surgeries every ten years to sustain energy for the devices.

Meanwhile, the cost of the surgery, as Cai said, is "far beyond the reach of many people."

For the 2008 model year Swedish car manufacturer Saab will come out with a redesigned Saab 9-3 range. The new variants of the 9-3 will come with more aggressive styling cues than their predecessors. Aside from exterior design changes, the new 9-3 range will also offer an all-wheel drive configuration and a selection of powerful gasoline engines.

On the outside , Saab revised the front, side, and rear styling cues of the 9-3. The front of the new 9-3 exhibits styling cues was taken out of the Aero X Concept which was unveiled at the 2006 International Geneva Motor Show. The ?Clamshell? hood is the most notable similarity that the third generation 9-3 has with the Aero X Concept.

Aside from the new hood design, the 9-3 also comes with new bumper moldings for the 2008 model year. The headlight and taillight configuration of the new 9-3 also received modifications. The extent of the redesign on the exterior of the Saab 9-3 includes the new design for the doors and their corresponding door handles. For the Sport Sedan trim level of the 9-3, 70 percent of the external body panels are new. This shows that the company has changed a lot in the exterior of the car.

Other notable external changes made to the Saab 9-3 include the flat wiper blades and new alloy wheels. The flat wiper blades produce less noise when battered by strong winds as compared to the previous wiper blades used on the 9-3 range. Two external colors are also added to the range according to Saab. One of the two new colors is the same as that used on the Aero X Concept which is Snow Silver.

In terms of performance, the 2008 Saab 9-3 range boasts of 100 percent rear torque transfer. The new all-wheel drive configuration gives better stability and handling for the new 9-3. The all-wheel configuration provides an improved traction for the car in any road condition.

Engine choice for the 2008 Saab 9-3 range includes the 2.8-liter V6 turbocharged engine which can produce as much as 280 horsepower. With the Sports Sedan trim level , the uprated V6 engine can propel the 9-3 to 60 miles per hour from a standstill in just 6.3 seconds. From 50 miles per hour to 75 miles per hour, the engine will only take the engine 7.9 seconds.

According to Saab, the new engine features a lightweight, all aluminum construction, variable inlet valve timing, twin scroll turbocharger , and hydroformed exhaust manifolds. The new manifold features stainless steel liners and improved air injection for a better cold starting capability.

The Saab 9-3 also comes standard with a Tire Pressure Monitoring system which warns drivers if their tires are under inflated. The system pinpoints which tire have a pressure below the set standard. The entertainment system that comes with the Saab 9-3 is a Bose Centerpoint Surround Sound audio system.

?We are introducing significant developments across three key areas: design, performance and handling," says Jan ?ke Jonsson, the Managing Director of Saab Automobile.
