Objective To investigate the effects of atorvastatin on the experimental autoimmune encephalomyelitis(EAE)and the underlying mechanism of immunoregulation.Method The Wistar rats were used to establish EAE model.After oral administration of 2, 8 mg? kg~(1)?d~(1)of atorvastatin, the rats were examined for the development of neurological signs, changes of histopathology and the expression of IL-4 and MMP-9.Result Though high dose treatment with atorvastatin, the frequency of EAE attacks degreased from 76.67% to 33.33%(P=0.008);the extent of inflammation degreased from 3.2?1.1 to 1.3?0.4(P=0.01);and the number of MMP-9 positive cells degreased from 37?7 to 26?5(P= 0.001), the expression of IL-4 could be increased from(0.35?0.12)ng/ml to(0.68?0.23)ng/ml (P=0.05).Conclusion Atorvastatin can reduce the inflammation and produce the recover of the neurological harm because of the changes of MMP-9 and IL-4.

Objective To investigate the proportion of streptococus pneumonia(SP), haemophilus influenzae (Hi),branhamella catarrhalis (BC), chlamydia pneumonia (CP) and mycoplasma pneumonia (MP) in children with acute pneumonia.Methods Fifty-three hospital-treated children with acute pneumofmonia were included in a prospective study. The enzyme immunoassay was used to detect antibodies in paired sera against non-capsulated Hi, Hi type-B capsular polysaccharide and whole cell, antibodies against pneumococcal pneumolysin, C-polysaccharide and pneumococcal pneumolysin, C-polysaccharide, surface protein A in circulating immune complexes and antibodies against BC and MP. Antibodies against CP by immunofluorescence in paired sera as well as blood cultures were detected in these cases.Results The evidence of bacteria infection was demonstrated in 32 cases (60.4 %) among children with acute pneumonia, of which 11 cases had 2 or 3 organisms coinfection. In these causative agents,SP and CP were the most common organisms (11/53 cases respectively,20.8 %), followed by MP (7/42,16.7 %),Hi(7/53,13.2 %).Conclusion SP,Hi,CP and MP are common causative agents of children with acute pneumonia and multi-agents coinfection isn′t ingnored in our empiric antibiotic therapy for the disease.

OBJECTIVETo compare the difference of the clinical efficacy on common peroneal palsy between the comprehensive therapy of electroacupuncture, moxibustion and moving cupping method and western medication.

METHODSNinety cases of common peroneal nerve palsy were randomized into a comprehensive therapy group and a western medication group, 45 cases in each one. In the comprehensive therapy group, electroacupuncture was applied to Yanglingquan (GB 34), Zusanli (ST 36), Xuanzhong (GB 39), Jiexi (ST 41), Taichong (LR 3), Zulinqi (GB 41) and the others, combined with warm moxibustion and moving cupping on the lateral side of the affected leg. The comprehensive therapy was used once a day. In the western medication group, vitamin B1 , 10 mg each time, 3 times a day; and mecobalamine, 0. 5 mg each time, three times a day were prescribed for oral administration. In the two groups, 15 days made one session, and the efficacy was observed after 2 sessions treatment.

RESULTSThe total effective rate of the improvement of sensory function and motor nerve function was 97. 8% (44/45) in the comprehensive therapy group and was 82. 2% (37/ 45) in the western medication. The efficacy in the comprehensive therapy group was better than that of the western medication (P<0. 01). The electrophysiological examination showed that the amplitude of motor conduction of deep peroneal nerve and that of sensory conduction of surficial peroneal nerve after treatment were improved remarkably as compared with those before treatment in the comprehensive therapy group (both P<0. 05). The amplitude of motor conduction of deep peroneal nerve was improved significantly in the comprehensive therapy group as compared with that in the western medication group (P<0. 05).

CONCLUSIONThe comprehensive therapy of electroacupuncture, moxibustion and moving cupping method achieves the significant efficacy on common peroneal nerve palsy as compared with western medication.

BACKGROUND: Paraquat (PQ) is an effective herbicide and is widely used in agricultural production, but PQ poisoning is frequently seen in humans with the lung as the target organ. Clinically pulmonary pathological changes are often used to predict the severity and prognosis of the patients. In this study, we observed the expression of heat shock protein 70 (HSP70) in rat lung after PQ poisoning and to investigate the therapeutic effects of ulinastatin. METHODS: Seventy-two adult healthy SD rats were randomly divided into a control group (group A, n=24), a poisoning group (group B, n=24), and an ulinastatin group (group C, n=24). The rat models of acute PQ poisoning were established by intra-gastric administration of 80 mg/kg PQ to rats of groups B and C, and the rats of group C were intra-peritoneally injected with 100000 IU/kg ulinastatin 30 minutes after poisoning. The expression of HSP70 in lung tissue was observed, and W/D and histopathological changes in the lung tissue were compared 12, 24, 48 and 72 hours after poisoning. The expression of HSP70 in the lung tissue was assayed by using RT-PCR. All quantitative data were processed with one-way analysis of variance to compare multiple sample means. RESULTS: Compared to group A, the expression of HSP70 in the lung of rats in groups B and C increased significantly at all intervals (P<0.05). The pathological changes in lung tissue of rats with PQ poisoning included congestion, leukocytes infiltration and local hemorrhage, whereas those of group C were significantly lessened. CONCLUSION: Ulinastatin may ameliorate acute lung injury to some extent after PQ poisoning in rats by enhancing the expression of HSP70.

BACKGROUND: Paraquat (PQ) is an effective herbicide and is widely used in agricultural production, but PQ poisoning is frequently seen in humans with the lung as the target organ. Currently, there are many studies on lung injury after PQ poisoning. But the kidney as the main excretory organ after PQ poisoning is rarely studied and the mechanisms of this poisoning is not very clear. In this study, we observed the expression of caspase-3 and livin protein in rat renal tissue after PQ poisoning as well as the therapeutic effects of ulinastatin. METHODS: Fifty-four Sprague-Dawley (SD) rats were randomly divided into three experimental groups: control group (group A), paraquat poisoning group (group B) and ulinastatin group (group C), with 18 rats in each group. Rats in group B and group C were administered intragastrically with 80 mg/kg PQ, rats in group C were injected peritoneally with 100000 U/kg ulinastatin once a day, while rats in group A were administered intragastrically with the same volume of saline as PQ. At 24, 48, 72 hours after poisoning, the expression of livin in renal tissue was detected by Westen blotting, the expression of caspase-3 was detected by immunohistochemistry, and the rate of renal cell apoptosis was tested by TUNEL detection. The histopathological changes were observed at the same time. RESULTS: Compared to group A, the expression of caspase-3 in the renal tissue of rats in groups B and C increased significantly at any time point. Compared with group B, the expression of caspase-3 in renal tissue of rats in group C decreased. Compared with group A, the expression of livin in renal tissue in rats of groups B and C increased significantly at any time point (P<0.01), especially in group C (P<0.01). TUNEL method showed that the rate of renal cell apoptosis index was higher in group B at corresponding time points than in group A (P<0.01), and was lower in group C at corresponding time points than in group B (P<0.01). CONCLUSION: UTI has a protective effect on the renal tissue of rats after paraquat poisoning through up-regulating the expression of livin and down-regulating the expression of caspase-3, but the regulation path still needs a further research.
