Trauma is one of the main reasons for the death and disability in children.Ultrasonic tech-nology has been applied in the early assessment and diagnosis of trauma.it is quick,effective,non-invasive, fast imaging,mobile and suitable for different patients and different parts of the body.It has been used to as-sess the organs in patients with severe trauma widely.

Objective To investigate effects of driving fatigue on working memory. Methods The control group included 12 taxi drivers after adequate rest while the fatigue group included 27 taxi drivers who had been driving for 10h. Digit memory span, words span, Digit Subtraction Test, Random Number Generation test were used. Results Compared with the control(6.60 ±0.40,90.67 ±6.65,158.27 ±29.12,0.30 ±0.06,24.29 ±10.59,35.90 ± 10.64 ), driving fatigue group were significantly( P ＜ 0.05 )different in the number of backward number memory span( 5.37 ± 0.72 ), percentage of number of right reaction of the number of total reaction of Digit Subtraction Test(79.95 ± 8.04), total number of RNG( 88.33 ± 19.48 ), RNG(0.40 ± 0.05 ), Coupon( 12.35 ±12.88), NSQ(49.72 ± 8.06). Conclusion Driving fatigue can decline the working memory.

Objective:To assess the value and indication of endoscopic intervention for acute severe pancreatitis(ASP).Methods:A series of consecutive patients with (26 cases) was treated mainly with endoscopic naso-biliary drainage(ENBD),sphincterotomy (EST) as well as drugs,Abdominal pain duration:raised serum amylase period surgical intervention rate mortality rate and average be in hospital number of days.Results:Abdominal pain duration was (2.5±1.5) days in treatment group with endoscopic and (5.1±2.4) days in control group respectively (P<0.05),raised serum amylase period was (2.8±1.3) days in treatment group with endoscopic and (4.8±1.8) days period in control group respectively(P<0.05),mortality rate was 3.85% (1/26) in treatment group with endoscopic while 16.67% (5/30),P<0.05,average be in hospital number of days was (17.2±5.2) days in treatment group with endoscopic and (26.2±18.2) days in control group respectively.Conclusion:ENBD+EST the intraductal pressure can be lowered and the cause of occlusion be relieved with therapeutic effect.It is considered that endoscopic intervention is a practic of choice for selected.

The detection wavelength was at 344nm.Results: The recovery of the added sample was 102.8% and RSD was 2.2%. Conclusion: This method is simple and the result is reliable.

Objective To review the results of operative treatment of the distal radius fractures. Methods The group of 12 cases were classified accorded to universal classification. There was 1 case of type Ⅲ, 3 cases type ⅣA,2 cases type ⅣB, 5 cases type ⅣC and 1 case type ⅣD. Five of them were checked preoperatively by spiral CT and three dimensional evaluation. They were given respectively treatment by external fixation, by volar or dorsal buttress plate, with or without percutaneous K wires. Results The average period of follow up was 12 months. 9 cases were excellent and 2 cases were good. The excellent and good rate was 91.7%. Conclusions Operative interventions for intra articular fractures of distal aspect of the radius should be considered when non operation management failed. The spiral CT and three dimensional evaluation can reveal enough information about the fracture preoperatively. The proper operative method should be chosen according to the fracture type.

Objective To appraise the efficacy,survival rate and toxicity of GEM+NVB regimen in retreatment of 24 Advanced NSCLC treated by TAX+DDP regimen.Methods 24 patients with Advanced NSCLC received chemotherapy of GEM+NVB regimen.We evaluate the efficacy,survival rate and toxicity after two periods.Results Among these 24 patients,there was no complete response.Rates of partial response is 29.2 %,the average survival period is 28 weeks.One year survival rate is 34.3 %.Conclusions GEM+NVB regimen is effective as second-line chemotherapy for the Advanced NSCLC patients that have ever been treaded by TAX+DDP regimen.

ObjectiveTo investigate the applying value of nerve root retractor in lumbar intervertebral disc operation.Methods116 consecutive patients underwent lumbar discectomy performed with a new approach using a series of semi-tubular retractor with consecutively increasing diameters, and their clinical data was analyzed retrospectively.ResultsThe mean operative time was 30～90 min per level, average 50 minutes and estimated blood loss was 50～200 ml per level, average 120 ml, no complications occurred. All patients were followed up 3 to 18 months after operation. All patients had substantial relief of their lumbago and radiculopathy, in which 96 without any symptoms, 3 cases with gently lumbago and limb numbness, 8 cases with gently lumbago, and 9 cases with lightly limb numbness.ConclusionThe nerve root retractor for lumbar discectomy made specially by ourselves can facilitate a good exposure to lumbar disc and intervertebral space, prevent injury of nerve roots or cauda equina and decrease volume of bleeding during operation, so as to make the procedure safe and effective.

Objective To study the characteristics of the central part of the nociceptive system in acute myelitis (AM) with contact heat evoked potentials (CHEPs) and to document the potentials in patients with AM.Methods Twenty patients with AM were recruited in this study as an experimental group,and twenty healthy subjects were chosen as a control group.A heat foil was used to elicit pain and CHEPs.Thermal stimuli were applied at 54.5 ℃ at five sites:the dorsum of the hand,the proximal volar surface of the forearm,the skin of the leg 5 cm proximal to the medial malleolus,and at the C7 and T12 acupuncture locations.The latency and waveform of the evoked potentials were recorded.The conduction velocity of the A8 fibers of the peripheral nerves and of the spinal part of the spinothalamic tract were analyzed.The somatosensory evoked potential (SEP) and sensory conduction velocity (SCV) of the limbs were also examined,and the results were compared with the CHEP results.The results were compared between the two groups.Results The N 550 latencies of the CHEP on the dorsum of the hand,the inside of the leg,and at C7 and T12 were prolonged significantly in the patients with AM compared to the healthy controls.There were no significant differences in the nerve conduction velocity of the Aδ fibers and the velocity or amplitude of sensory nerve conduction in the limbs between the groups.The conduction velocities of the spinothalamic tract were significantly reduced in the patients with AM compared to the control group,while the peak latencies of N13 and the interpeak latencies of N9-N13 and N13-N20 in the AM patients were significantly prolonged compared to the healthy persons.In the patients with AM,CHEP abnormality in the lower limbs (17/20,85％) was significantly higher than in the upper limbs,total CHEP abnormality and CHEP abnormality in the lower limbs were significantly greater than SEP abnormality.Conclusion Persons with AM have abnormalities in the central part of the nociceptive system.When used with MRI and other electrophysiological examinations,CHEP may contribute to diagnosing AM.It could be helpful in the differential diagnosis of AM from motor neuron diseases and peripheral nerve lesions.It is of great potential value in clinical practice.

Objective The research aimed to probe into the complications of the treatment that endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy (ERCP/EST) combined with laparoscopic cholecystectomy (LC) for the patients suffered from gallstone disease combined with common bile duct stones and investigate the nursing methods.Methods One hundred and twenty-four patients suffered from gallstone disease combined with common bile duct stones were included in this retrospective analysis.At first,they underwent the treatment of ERCP/EST,and underwent LC in 1 to 5 days later.All the clinical data were collected and analyzed.Results Of all the patients,104 patients successfully underwent the treatment of ERCP/EST.And of the 104 patients,100 patients successfully underwent LC,the other 4 patients underwent open cholecystectomy.Nineteen complicated with acute pancreatitises,one with hemorrhage and two suffered from infections of bile duct were observed in this study.Conclusions Combination of ERCP/EST with LC is a safe and effective treatment for gallstone disease combined with common bile duct stones.The preoperative psychological counseling,and the surveillance and nursing of complications play significant roles in the successful treatment.
