BACKGROUND:Operation is the main therapy for protrusion of lumbar intervertebral disc.The researches have indicated that non-operation therapy can improve effectively its clinical symptoms.OBJECTIVE:To observe the effect of "three points and five methods"therapy on analgesia of radiculalgia in protrusion of lumbar intervertebral disc and on recovery of motor function in lumbar region and lower limbs.DESIGN:Non-randomized concurrent control study based on the patients.SETTING:Orthopedic department and college of acupuncture and massage of one university-affiliated Hospital.PARTICIPANTS:Totally 210 inpatients of lumbar vertebral disorders were selected from Orthopedic Department of First Affiliated Hospital of Henan College of Traditional Chinese Medicine and Department of Acupuncture and Massage of Third Affiliated Hospital from March 1999 to June 2003,which were randomized into experimental group (n=108) and control group(n=102).METHODS:"Three points and five methods" therapy was adopted in experimental group and the traditional manipulation was for the control.The evaluation on pain and motor function was carried on at minutes 5,10,30,and hours 1,2,...,24 successively for statistical analysis.RESULTS:Total effective rate was 94.44% and the average time of analgesia was(18.40±2.11) hours in the experimental group.Total effective rate was 82.35% and the average time of analgesia was (10.60±2.63) hours in the control group. The analgesia effect and evaluation results on comprehensive function in the experimental group were superior to that in the control group(t=4.86,4.42,P < 0.01).CONCLUSION: "Three points and five methods" therapy releases lumbar pain, improves lumbar symptoms and recovers motor function of lower limbs for the patients with radiculalgia in protrusion of lumbar intervertebral disc.

The people died from H5N1 avian influenza virus,which was diagnosed by serological test.The remarkable pathohistology change is as follows:thick and homogeneous things dyed red can be seen on the face of pulmonary alveoli;the alveolar septum become wider and there are a lot of inflammatory cells in the pulmonary alveoli.Above all,we think that the histology changes can provide evidence to help coroners identify people died from H5N1 avian influenza virus or not.

The Neutral detergent method (AACC method) for determining insoluble dietary fiber in cereals and cereal foods has been used in this experiment. The results showed that the suitable size of the sample was 40-mesh and the better period for digestion in hot neutral detergent solution was one hour for determination. Decahydronaphthalene as a defoaming agent was better than n-octane. The average recoveries of two different ways were from 94.1% to 100.4%. The coefficient of variation for eight wheat samples was 1.8%. Because of its simple equipment, easy operation and good accuracy, this method would be suitable for determination of cereals and cereal foods.

Objective To observe the effect of changes in CD34+ cell level on various degrees of chronic heart failure (CHF) in the elderly. Methods The enrolled patients were divided into four CHF groups according to the New York Heare Association(NYHA) functional class: NYHA class I (n=23), Ⅱ (n=27), Ⅲ (n = 20) and IV group (n= 16) , and there were 41 healthy controls over the same period. The levels of peripheral blood CD34+ cells were measured, and the tumor necrosis factor-α (TNF-α). its soluble receptors (sTNFR-1 and sTNFR-2) and vascular endothelial growth factor (VEGF) were also measured. Results The levels of CD34+ cells were elevated in the early CHF and depressed in the advanced CHF in elderly patients. The levels of CD34+ cells were (0. 6± 0.2) 109/L in control group, (2.4±0. 4) 109/L in NYHA class I group, (1.9±0.2)×109/L in NYHA class Ⅱ group, (1.3±0.1)×109/L in NYHA class Ⅲ group and (0.5±0.2)×109/L in NYHA class Ⅳ group, respectively (all P<0.01).And TNF-α, sTNFR-1, sTNFR-2 and VEGF were increased in severe chronic left ventricular failure CNYHA class IV vs. I group:TNF-α: (61.4± 15.7) ng/L vs. (28.4±10.8)ng/L; sTNFR-1: (2820.9±1282.8)ng/L vs. (690.8±62.7) ng/L; sTNFR-2: (4113.1±1102.2) ng/L vs. (740.8± 112.3)ng/L; VEGF: (996.3±487.1)ng/L vs. (423. 3±147. 9)ng/L, all P<0. 013.
