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 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.

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.

Morinda citrifolia L.(noni) has been used as a folk remedy for thousands of years and reported to have a broad range of therapeutic effects.Recent studies of noni have indentified some of its useful pharmacologic compounds and indicated its anti-cancer and anti-oxidation mechanisms.The recent advances in noni researches are reviewed.

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 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 survey the effects of repetitive transcranial magnetic stimulation (rTMS) on learning,memory and the dendrite morphology of neurons in the CA1 area of the hippocampus in rats with vascular dementia.Methods Thirty-six male SD rats were divided into a control group,a model group and a rTMS group randomly,12 rats in each group.A model of vascular dementia (VaD) was established using the two vessel occlusion method.The rats in the rTMS group were given rTMS treatment.The rats in the other two groups had no therapy.The Morris water maze (MWM) test was used to evaluate the rats' learning and memory abilities on the 30th day after the operation.After the MWM test the dendrite morphology of the pyramidal cells in the CA1 area of the hippocampus was detected after Golgi-Cox staining using light microscopy and the expression of brain-derived neurotrophic factor (BDNF) was detected using immunohistochemistry methods.Results The average MWM escape latency in the rTMS group was shorter than in the model group on the 1 st,2nd,3rd and 4th day.The number of crossings of the platform quadrant in the rTMS group was significantly more than in the model group.The number of branch segments,their total length and the dendritic spine density of pyramidal cell dendrites in the CA1 area of the hippocampus were all significantly lower in the model group than in the control group,but in the rTMS group all these indicators were significantly improvedcompared with the model group.The expression of BDNF in the CA1 area in rTMS group was significantly higher than in the model group.Conclusions rTMS can improve learning and memory in VaD,at least in rats.The mechanism may be associated with rTMS promoting the expression of BDNF in the hippocampus and so improving the dendrite morphology of pyramidal cells.

Objective To evaluate the effect of multiple adhesion molecules ICAM-1、CD_ 44 V6、CD_ 28 、E-cad and CEA in organic selection of gastric carcinomatous metastasis.Methods Eighty-four gastric carcinoma cases(32 cases without metastases,52 cases with transfer to liver、marrow、lymphonode、lung、kidney or belly cavity),were take operation sample or tissue under gastroscopy,being made cells single by primary culture,then were detected the expression of 5 kinds of adhesion molecules by ABC immunohistochemistry,positive rate was recorded.Results ICAM-1 had high expression in cases with marrow or lung metastasis,while low expression in cases with lymphonode metastasis.CD_ 44 v6 had high expression in cases with lymphnode or liver metastasis.CD_ 28 had high expression in cases with liver、lung or kidney metastasis.E-cad had high expression in cases with marrow metastasis,while low expression in cases with other metastasis.CEA had especially high expression in cases with liver、belly cavity or lymphnode metastasis.Conclusion High or low expression of adhesion molecules ICAM-1、CD_ 44 V6、CD_ 28 、E-cad and CEA plays a certain role in organic selection of gastric carcinomatous metastasis.
