Insulin receptor substrate(IRS)-1 and IRS-2 expression levels of liver tissues and skeletal muscle in intrauterine growth retarded(IUGR)rats were investigated by RT-PCR and immunohistochemistry.An IUGR animal model was established by maternal nutrition restriction during pregnancy.IRS-2 expression level of liver tissue and IRS-1 expression level of skeletal muscle in IUGR rats at 0 and 3 weeks old were significantly lower than those in normal rats at the same age respectively,and insulin resistance was induced in IUGR,and these findings might be the molecular mechanisms susceptible to metabolic syndrome in IUGR rats.

Objective To observe the effect of angiotensin-converting enzyme inhibitors (ACEI) on anemia and erythropoietin (EPO) requirements in maintenance hemodialysis patients. Methods Ninety maintenance hemodialysis patients with hypertension and anemia were divided into 2 groups by random digits table, observation group (45 cases, using ACEI as antihypertensive treatment), control group [45 cases,using calcium channel blocker (CCB) as antihypertensive treatment]. The follow-up period after starting ACEI or CCB therapy was one year. The hemoglobin concentration, serum EPO, EPO requirements were compared after 0, 2, 4, 6, 8, 10, 12 months' treatment. Results In response to ACEI, the mean hemoglobin value in observation group decreased progressively, reaching statistical significance after 6 months, and it had significant difference compared with that in control group [6 months: (94.21±9.20) g/Lvs. (105.55±9.16) g/L,12 months: (95.90±6.75) g/L vs. (105.81±4.45) g/L,P <0.05]. The EPO requirements experienced a progressive increase in observation group and reached statistical significance after 8 months, compared with those in control group [8 months: ( 10 090.75±1918.35) U/week vs. (7010.32±1600.15) U/week, 12 months: (11 586.39±2009.76) U/week vs. (7068.48±1615.35) U/week,P<0.05].Serum erythropoietin concentration remained stable during the study in two groups. Conclusion ACEI can worsen anemia and reduce the efficacy of EPO in maintenance hemodialysis patients.

This paper reported a new method of Armillaria mellea isolation-Gastrodia elata tissue isolating. Compared with normal isolating method-rhizomorph isolating method, it showed that the success rate of new method (78% ) was higher than the rhizomorph isolating method (16% ) , besides this, the new method was easier, and growth characteristic of obtained strain was superior to that obtained from rhizomorph isolating method.

Abstract: Objective To explore the effects of continuous light and benzene exposure on peripheral blood erythrocyte - Methods parameters and expression of miR 144/451 in the bone marrow of mice. This was a 2×2 factorial design. Photoperiod ， ， factor was set as normal and continuous light levels and mice were treated for 12 hours/12 hours light/dark or 24 hours light - respectively. The benzene exposure factor was set as non exposure and exposure levels. Mice were exposed to benzene by static 3 ， inhalation with a mass concentration of 0.0 and 32.5 mg/m for three hours per day five days per week for a total of four weeks. ， ， Specific pathogen free male C57BL/6 J mice were randomly divided into negative control group simple continuous light group - - ， ， simple benzene exposure group and combined exposure group with 12 mice per group. After benzene exposure peripheral ， blood was collected for the detection of erythrocyte parameters in four periods. After the mice were sacrificed the expression of - - - - miR 451a and miR 144 5p was detected by real time fluorescence quantitative polymerase chain reaction in bone marrow Results （ ）， ， tissues. The hematocrit volume HCT mean corpuscular volume mean corpuscular hemoglobin concentration （ ） - MCHC and mean corpuscular hemoglobin in peripheral blood and the relative expression of miR 451a in bone marrow tissue （ P< ） ， were statistically significant only in mice with benzene exposure all 0.05 . Among them the MCHC of benzene exposed （P< ）， （ P< ） - mice increased 0.05 but the other four indexes decreased all 0.05 compared with non benzene exposed mice. In thenegative control group the change of red blood cells count hemoglobin level and HCT in peripheral blood were rhythmical all P < ） ， （ P > ） rhythmical 0.05 . However the indexes above were out of rhythm all rhythmical 0.05 in the simple continuous light group and the - （ P > combined exposure group. The change of hemoglobin level and HCT of peripheral blood were also out of rhythm all rhythmical ） - - 0.05 in the simple benzene exposure group. The relative expression of miR 451a in bone marrow tissues of negative control （ P < ）， - group and simple continuous light group was rhythmical all rhythmical 0.05 while the relative expression of miR 451a in simple - - （ P > ）Conclusion benzene exposure group and combined exposure group was out of rhythm all rhythmical 0.05 . Benzene exposure ， induced changes in erythrocyte parameters of mice are independent effect and its mechanism may be related to the rhythmic - ， expression disorder of miR 451a in bone marrow tissues. Continuous light exposure benzene exposure and their interactions can ， interfere with the circadian rhythm of erythrocyte parameters such as red blood cell count hemoglobin and HCT to some extent.

To report a boy with reflex seizures induced by micturition.He suffered from seizures during micturition for four yesrs.The clinical symptoms consisted of head backwards,limbs dithering,sometimes accompanying tumble.During the episodes of the seizure,his consciousness did not lose.Few seizures showed only eyes up-staring for several seconds.The livelong process of micturition was often interrupted by seizures for several times.When he finished or stoped micturition,the seizures did not occur again.His seizures could not be induced by free of micturition or other stimulative factors.The interictal EEGs showed that background asymmetry manifested as the lower amplitude and irregular rhythm in the left hemisphere,sharp or sharp and waves in right hemisphere,especially mid and back temporal.There also had sharp,spike,and spike and waves in many regions of double spheres in interictal EEGs.The other assistant check-ups were normal.while this disease was infrenquncy,it would be worthy to regard.

Objective To investigate the role of electromyography(EMG) in diagnosis of nervous system diseases in children.(Met)-hods EMG tests were carried out in 354 patients with nervous system diseases,and the data and results of EMG tests were analyzed.Results One hundred and sixty-six patients′ results of EMG were abnormal.Among these abnormalities,36 cases were myogenic,47 cases were neurogenic,abnormalities of 69 cases were located in peripheral nerves,3 cases got positive in repetitive nerve stimulation(RNS),and 11 cases were on the borderline.In 36 myogenic patients,clinical diagnosis were as follow: progressive muscular dystrophy(PMD,18 cases),polymyositis(2 cases),mitochondrial encephalomyopathy(1 case), and the other 15 cases had no definite diagnosis.In 47 neurogenic patients,the diagnosis were spinal muscular atrophy(SMA,29 cases),sequela of poliomyelitis(2 cases),acute transverse myelitis(ATM,4 cases),and the other 12 patients had no definite diagnosis.In 69 cases of peripheral nerve abnormality,diagnosis were injury of brachial nerve(23 cases),hereditary motor sensory neuropathy(HMSN,2 cases),Guillain-Barre syndrome(GBS,9(ca)-ses),chronic inflammatory demyelinating polyradiculoneuropathy(CIDP,1 case),injury of facial nerve(4 cases),injury of common(pe)-roneal nerve(6 cases),metachromatic leukodystrophy(MLD,1 case),and the other 23 patients had no definite diagnosis.Three patients who got RNS positive were all diagnosed myasthenia gravis(MG),and ocular type(1 case),general type(2 cases).Eleven patients whose EMG results were borderline were all diagnosed indefinitely.One hundred and eighty-eight patients had normal results of EMG test.The diagnosis of these patients were included ocular MG(21 cases),cerebral palsy(CP,5 cases),ATM(2 cases),polymyositis((1 case)),and some other nervous system diseases(21 cases),and the other 138 were diagnosed indefinitely.Conclusions 1.EMG plays an important role in definite diagnosis of PMD,SMA,poliomyelitis and nerve injury;2.EMG can provide clue or basis in the differential(dia)gnosis of nervous system diseases which involved lower motor unit;3.EMG test has very low positive results in children with MG;(4.EMG) has little help in diagnosis of diseases involved upper motor unit only.
