Objective To investigate the effect of total sleep deprivation (TSD) shown in the electroencephalogram (EEG) power spectra in healthy young men. Method 20 healthy young male volunteers (19～22 years old) were subjected to 50 hours of TSD. EEGs were recorded 8 times (6 hours intervals) during TSD. EEG power was calculated for six bands at all 16 derivations.Results 50 hour TSD induced an increase in ? power at the other derivations except both occipitals ( P

Acupuncture therapy for regaining consciousness activates soreness, numbness, distention, heaviness, radiating and moving, electric shock and ant climbing sensations at the specific acupoints in the stroke patients. Radiating and moving sensations are the summary of needling sensations such as soreness, numbness and twitching presenting during lifting and thrusting manipulation. These sensations are the essential factors of the therapeutic effect of regaining consciousness. Radiating sensation refers to the conduction along meridians and radiation of soreness and numbness. Moving sensation refers to the local muscular twitching at acupoints and the involuntary movement of limbs, joints and the distal. Acupuncture at the specific acupoints achieves radiating and moving sensations for promoting the circulation in meridians, regulating qi and mind and balancing yin and yang in stroke patients. This therapy was introduced in the paper in view of acupoint location, needle insertion and manipulation.

Objective To observe and compare the antiemetic effectiveness and adverse effects of magnetotherapy plus the 5 -hydroxytryptamine (5-HT3 ) receptor inhibitor granisetron hydrochloride with that of granisetron hydrochloride alone with chemotherapy patients. Methods Sixty-four patients were randomized to receive either granisetron hydrochloride alone ( control group: granisetron hydrochloride 3 mg intravenous infusion before chemotherapy, from the 1st day of chemotherapy until the day after the chemotherapy course was completed) or magnetotherapy plus granisetron hydrochloride ( treatment group: the same granisetron hydrochloride regimen plus rotatory magnetotherapy of 1 h/time every day after chemotherapy). The baseline characteristics of the two groups were similar. The patients' emesia was evaluated according to the WHO's criteria. The density of 5-HT, in serum was detected by enzyme-linked immunosorbent assay ( ELISA). Results In terms of acute vomiting, there was no significant difference between the two groups, but in terms of tardive vomiting, the effectiveness in the treatment group was significantly better than in the control group. The densities of S-HT, in serum in the treatment and the control group were (225.32±57.29 ) ng/ml vs (213.00±53.29 ) ng/ml before chemotherapy and (273.88±5.42) ng/ml vs ( 313.17±76.36 ) ng/ml after chemotherapy, a significant difference. The rates of adverse events were 36.36% and 48.39% respectively in the treatment group and control group, a difference which was not significant. Conclusions Magnetotherapy plus granisetron hydrochloride is more effective than granisetron hydrochloride alone, and the two therapies have a synergistic effect. Adverse events didn't rise in the treatment group.

Objective To discuss the clinical outcome of the modified super large dorsal metacarpal artery flap in reconstruction of circumferential fingertip avulsion. Methods Twenty-four patients with circumferential fingertip avulsion were treated by the modified super large dorsal metacarpal artery flap from January 2004 to August 2008. There were six index fingers, 11 middle fingers, five ring fingers and two little fingers with surface defects beyond the distal interphalangeal joint and the distal degloving length ranged from 0.8 cm to 3.1 cm. Emergency operation was performed on 22 fingers and stage Ⅱ surgery was done for distal skin necrosis of two fingers. Results Twenty-one patients with 21 fingers were followed up for 6-28 months, which showed that all flaps survived, with satisfactory appearance and function, and that the point discrimination of flap was for 6-9 mm ( average 7.6 mm). Conclusion Modified super large dorsal metacarpal artery flap is an ideal method for reconstruction of the circumferential fingertip avulsion with advantages of easiness, convenience and short treatment period.

Objective:To evaluate the clinical effect of retroperitoneoscopic renal pedicle lymphatic disconnection via extra-adipose capsule in the management of chyluria and to discuss the management of its complications.Methods:From August 2013 to June 2008,five patients with chyluria were admitted. All the patients were female,aged from 26 to 73 years,and disease course from 1 to 10 years.All the five patients had complained of intermittently voiding milky urine with varying degrees of weight loss,and fa-tigue,of whom two presented with flank pain and one with anemia.Their urine chyle tests were con-firmed to be positive.Preoperative cystoscopy found that chyluria was from the left side in 3 cases,and from the right side in 2 cases.Their proteinuria ranged from +to ++++.All the cases had been treated with the modified procedure by which lymphatic ligation was performed to hilar vessels and proximalureter via extra-adiposecapsule without disconnection of perirenal fat tissues.The operation time,intraoperative blood loss,postoperative intestinal function recovery,catheter time,drainage tube removal time and com-plications during operation were collected.Results:All the five cases were performed successfully.The operation time ranged from 75 to 170 minutes,mean (126.0 ±39.6)minutes,with the intraoperative blood loss 20 to 60 mL,mean (38.0 ±16.4)mL,and the postoperative intestinal function recovery time 1 to 3 days,mean (1.9 ±0.4)days.The catheter time was 1 to 4 days,mean (2.1 ±0.3)days and the drainage tube removal time ranged from 3 to 15 days,mean (9.3 ±1.8)days.Postoperatively lym-phorrhagia was found in two cases.No renal vessels injury occurred during operation.Chyluria of all the patients disappeared on the operation day with negative chyluria test after surgery.Furthermore,urine test revealed that proteinuria was totally negative.No recurrence was detected in our patients in the 9 to 31 months’follow-up.Conclusion:This modified procedure does not have to disconnect perirenal fat tissues and nephropexy during operation.It was characterized with shorter operation time,definitive effect and fewer complications.

Bones are stained into red color with feeding madder, but we do not know whether the fed madder can change the bone biomechanical properties and bone mineral contents in animals. In this research, we established a rat model with feeding madder. The bone biomechanical properties were detected by universal material mechanics, bone mineral contents were detected by inductively coupled plasma mass spectrometry and spectrometer, and red color material in bone was analyzed by high performance liquid chromatography. The results showed that bone biomechanical parameters in femur diaphysis in the 10% and 15% group rats were significantly higher than those in the control group after feeding madder for 6 months. The level of calcium, magnesium and zinc in femur diaphysis in 10% and 15% group rats were higher than those in the control group after feeding madder for 6 months. However, it was shown that the kidney congestion and hyperemia and the level of blood urea nitrogen and creatinine in the 15% group rats were significantly different compared to those in the control group rats after feeding madder for 6 months. The red colored material in bone is related to alizarin analyzed with high-performance liquid chromatography. The conclusion could be drawn that feeding 10% madder in diet was not toxic to the rats fed for 6 months, and it could improve bone biomechanical properties and increase bone mineral elements.
