The synaptic organization of monoaminergic and peptidergic fibers in the lateral horn of the rat spinal cord was studied under electron microscopy by immunocytochemistry ABC method. TH, 5-HT, SP and L-ENK immunoreactive fibers in the lateral horn were unmyelinated. In the cell clusters of the lateral horn these fibers appeared in the space between cell bodies and some pressed on the soma, but axosomatic synapses were seldom found. Many immunoreactive fibers ran along the dendrites, especially in the dendritic bundle. Occasionally a small bundle of unmyelinated fibers all contained the same kind of substance. Majority of the immunoreactive boutons formed axodendritic synapses. All the four kinds of neuroactive substancecontaining boutons or varicosities contained almost round clear vesicles or plus a few large granular vesicles. The SP and L-ENK varicosities included more large granular vesicles than the boutons did. Both symmetrical and asymmetical contacts were encountered in TH, 5-HT, SP and L-ENK boutons.

OBJECTIVE:To provide reference for rational use of glucocorticoid in the clinic. METHODS:The glucocorti-coid outpatient prescriptions collected from clinical departments of a hospital during Jan. 2013 to Jun. 2015 were analyzed statisti-cally in respects of glucocorticoid use,department distribution,DDDs,distribution of prescription diagnosis,etc. RESULTS:Of 15 000 prescriptions,there were 1 562 glucocorticoid prescriptions,with utilization rate of 10.4%;189 prescriptions were recog-nized as irrational ones,with irrational rate of 12.1%. The proportion of glucocorticoid in otorhinolaryngology department was the highest(27.66%),and irrational drug use was the highest in pediatrics department(16.12%);Dexamethasone injection was the most widely applied(44.88%);most of glucocorticoid prescriptions were used for acute bronchitis and bronchitis(267 pre-scriptions). CONCLUSIONS:The irrational glucocorticoid application has existed in the hospital,which deserved special atten-tion. Hence,prescription check and evaluation should be strengthened to promote the safety and efficacy of glucocorticoid in clini-cal application.

OBJECTIVE:To observe clinical efficacy and safety of nitric oxide (NO) combined with sildenafil in the treatment of neonatal pulmonary hypertension. METHODS:66 cases of neonatal pulmonary hypertension were selected and randomly divided in-to observation group and control group,with 33 cases in each group. 2 groups of patients were given Dopamine injection 5 μg/(kg· min),ivgtt. Control group was given NO 5-20 ppm;observation group received oral or nasal feeding of Citric acid sildenafil tab-lets,0.5-1.0 mg/kg,96 h,on the basis of control group. Both group received 3 d of treatment. Clinical efficacy of 2 groups were observed as well as the level of PaO2,PaCO2,SaO2,PAP,NO,ET-1,HIF-1α,EPO and Ca2+before and after treatment. The inci-dence of ADR was compared between 2 groups. RESULTS:Total effective rate of observation group was 96.97%,which was sig-nificantly higher than that of control group(75.76%),with statistical significance(P<0.05). There was no statistical significance in the levels of PaO2,PaCO2,SaO2,PAP,NO,ET-1,HIF-1α,EPO and Ca2+between 2 groups before treatment(P>0.05);com-pared to before treatment,PaO2,SaO2,No and Ca2+ levels of 2 groups increased significantly after treatment,while PaCO2,PAP, EPO,HIF-1,ET-1 significantly lowered and the observation group was better than the control group,with statistical significance (P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Sildenafil combined with NO is effective in the treatment of neonatal pulmonary hypertension and can effectively improve pulmonary hypertension and blood gas indexes with good safety.

0.05). Conclusion:There is bigger difference process of tumor apoptosis between different cell types in the same topography site. Survivin may play adjuvant roles and Bcl-2 may play main roles in the inhibition of cell apoptosis in SCLC while the case is just reversed in NSCLC,it suggests that there were different apoptosis inducing factor and different apoptosis pathway due to different cell type in NSCLC and SCLC.

Objective To summarize the features of multiple sclerosis (MS) in China. Methods The clinical manifestations and inducements of 413 MS patients are comprehensively analyzed using clinical statistical method. Other parameters are also analyzed by electromyography and brainstem auditory evoked potential. Results MS in China mainly invades young and middle-aged people, with a higher ratio in female than in male. MS was found mostly acute or subacute in onset and usually due to an inducement mainly consisting of common cold, fever, cyesis and fatigue. The first seen symptoms were various and complicated, but mainly showed different types of visual disturbance such as the acuity of vision decrease, constriction of visual field and diplopia. Limb paralysis, sensory abnormality and visual disturbance were found the commonest symptoms. Lhermitte’s sign was common. Paroxysmal symptoms as algospasm and seizure were relatively common. Electromyography and brainstem evoked potential showed that peripheral nervous system damage might occur in MS. Spinal cord and visual nerve were found the mostly invaded according to the clinical data. Conclusion The features of MS in China should be different from those in the western countries.

The ultrastructural characteristics of the lateral horn of the cat and rat revea-led by present study included:(1)The neurons of cell clusters in the lateral hornwere fusiform or oval,oriented rostrocaudally and possessed similar fine structures.The dendrites often protruded from the rostral and caudal poles of the cell bodies.The synapses on neuronal somata were sparse,for usually only 0-5 buttons contac-ted the plasmalemma in each neuronal profile.A little amount of neuropil existedbetween cell bodies in the cell clusters,even sometimes the plasma membranes ofadjacent cell bodies apposited directly.(2)Most dendrites in the lateral horn ranlongitudinally and paralleled with one another.Numerous dendrites aggregated inthe ventral part of the cell clusters,constituting a dendrite bundle in which adja-cent dendrites apposited directly and were surrounded by glial processes.(3)Manyunmyelinated fibers and fiber bundles ran longitudinally in the lateral horn.Theywere parallel with the neuronal and dendritic profiles.Unmyelinated fiber bundlesconsisted of the fibers with diameter less than one micron,and their terminal bottonsoften compacted together.(4)The majority of the synapses in the lateral horn wereaxodendritic synapses.A small number of axosomatic and axoaxonic synapses werefound,occasionally synaptic glomeruli and serial synapses were observed.Most ofthe buttons contained round clear vesicles and some plus a few granular vesicles.

Objective TO explore the etiology and pathogenesis of multiple sclerosis. Methods The information of pa-tients from 413 MS was analyzed comprehensively by the clinical statistical methods. Results Common cold was the com-monest factor causing MS, and fever,fatigue and childbirth were also the common causes. Immunological disturbance exis-ted in MS. CD~+_4 cell decreased in most of MS patients, but the distribution of CD~+_8 cell was not regular. The level of sexhormones was abnormal in MS,but it was not the same in male and female. There were three patients having family histo-ry of MS. Conclusion Virus infection,sex hormones and heredity factors are all related to MS through facilitating immu-nological disturbance.

Objective To compare the therapeutic effect of electroacupuncture, warm needling therapy and acupuncture on the third lumbar transverse process syndrome. Methods 90 patients were assigned to receive electroacupuncture therapy (n=30), warm needling therapy (n=30) and acupuncture therapy (n=30) for 20 times. They were assessed with Visual Analogue Scale (VAS) and Japanese Orthopaedic Association (JOA) scoring systems for lower back pain before and after treatment. Results The scores of JOA increased and the scores of VAS decreased significantly in all the groups after treatment (P<0.001). Both the scores were better in the electroacupuncture group (P<0.05). Conclusion Electroacupuncture, warm needling therapy, and acupuncture are effective on the third lumbar transverse process syndrome, among which the electroacupuncture is most effective.

Objective:To search for proteins interacting with ARA267-? with the yeast two-hybrid system in order to further investigate the function of ARA267-?. Methods:We screened a pretransformed human brain cDNA library with the pGBKT7-PHD-SET recombinant plasmid as a bait which express four PHD(plant homeodomain) and one SET[Su(var)3-9, Enhancer-of-zeste, Trithorax] conserved domains in ARA267-?.The plasmids in positive yeast clones were selectively identified by restriction analysis and DNA sequencing. The interactions were retested by yeast two-hybrid assay. Results: There were about six hundreds positive yeast clones on SD/-Ade/-His/-Leu/-Trp/2.5 mmol/L 3-AT/ X-?-Gal high-stringency selection plates. The pACT2-cDNA plasmids in sixty-five yeast clones were isolated and thirty-five cDNA inserts were sequenced. Sixteen different genes,including DR6(death receptor-6), PIAS3 (protein inhibitor of activated STAT3)and RanBPM(Ran-binding protein in the microtubule-organizing center), were identified after BLAST in GenBank. The yeast two-hybrid retest showed that all but RanBPM were true interactors of ARA267-?-PHD-SET. Conclusion: The ARA267-?-PHD-SET can interact with several distinct proteins. This suggests that ARA267-? is a protein having multiple functions. RanBPM might be a transcriptional factor.
