The anti-inflammatory of waterand fat-soluble alkoloids of Leon-tice Kiagnanensis (WSALK, FSALK ) were described after sc of WSALK (150, 300 mg/kg ) and FSALK (13, 26mg/kg ) . The increased capillary permeability in abdominal cavity and skin of mice induced respectively by 0.7% HAc and histamin were inhibited abviously. WSALK (75, 150, 300mg/kg, ip ) and FSALK (6.5, 13, 26mg/Kg, ip ) markedly inhibited the ear inflammation induced by xylene in mice, carrageenin-iaduces swelling of the ankle in normal on adrenalecto-mized rats, and carrageenin-induced pleurisy in rats. Both compound also inhibited the granuloma induced by cotton pellet after sc of WSALK 300, 600 mg/kg and FSALK 13, 26 mg/kg qd ? 7d.Both compound decreased the content of PGE in exudate formed after injecting carrageenin into the hind paw of rats. These results suggest that both compounds passesses the anti-inflammatory activity and their actions might be relatied to their inhibiting the synthesis or relase of pro-staglandin E.

OBJECTIVETo investigate the effects of spironolactone on the concentration of collagen type I, III in the myocardium of spontaneous hypertension rats (SHR).

METHODSTwenty 8-week male SHR were assigned randomly into spironolactone (SHR-SPIRO, n=10) and control groups (SHR-CON, n=10), sex-age matched Wistar Kyoto rats (WKY group, n=7) were also served as controls. The rats of SHR-SPIRO group were given 20 mg/(kg*d) of spironolactone, the rats of SHR-CON and WKY groups were given the same volume of distilled water. After 16 weeks, the concentration of collagen type I was analyzed with Western blot. The areas of collagen type I and III were observed under polarized light microscopy and the ratio of type I/III collagen was calculated through accumulation score.

RESULTSCompared with WKY group,the concentration of collagen type I in SHR-CON group was significantly higher (1.87 ±0.2 Compared with 1.21 ±0.7, P<0.05). After 16 weeks of treatment the concentration of collagen type I (1.42 ±0.05 Compared with 1.87 ±0.2, P<0.05) and I/III ratio in SHR-SPIRO group were significantly reduced (15.64 ±1.34 Compared with 20.8 ±3.04, P<0.05) compared with SHR-CON group; but there were no differences in accumulation area scores of collagen type III among three groups (368.3 ±30.2 Compared with 481.6 ±32.4 Compared with 406.2 ±45.3, P>0.05).

CONCLUSIONThe deposition of collagen type I in myocardium may be involved in myocardial fibrosis of SHR, and spironolactone can decrease the concentration of collagen type I, which may be one of the mechanisms for its therapeutic effects.

Objective:To analyze results of microbiological culture of lesion exudates and drug sensitivity test in patients with pemphigus, and to optimize the management protocol of pemphigus.Methods:Inpatients with pemphigus were collected from Department of Dermatology and Venereology, the First Affiliated Hospital of Anhui Medical University from January to December in 2008, and the results of microbiological culture of skin lesion exudates and drug sensitivity test were retrospectively analyzed.Results:A total of 176 patients were collected, and skin lesion exudate culture yielded 25 kinds of bacteria and 11 kinds of fungi in 156 (88.64%) patients. Of the 156 patients, 1 kind of pathogen was yielded in 104 (66.67%), and 2 or more kinds of pathogens were yielded in 52 (33.33%). Gram-positive cocci were detected in 134 (76.14%) cases, including Staphylococcus aureus in 80, Staphylococcus hemolyticus in 21, and Staphylococcus epidermidis in 16; Gram-negative bacilli were detected in 66 (37.50%) cases; fungi were detected in 24 (13.64%) cases. In addition, 89 (93.68%) of 95 relapsed patients showed positive culture results, 67 (82.72%) of 81 patients with newly developed pemphigus had positive culture results, and the positive rate significantly differed between the two groups ( χ2 = 5.22, P <0.05). Drug sensitivity test for Staphylococcus aureus isolates showed that 71 (97.26%) of 73 were sensitive to vancomycin, 69 (97.18%) of 71 to linezolid, and 61 (87.14%) of 70 to rifampin. Conclusion:Cutaneous infection, especially Gram-positive cocci infection, is very common in patients with pemphigus, and Staphylococcus aureus clinical isolates were highly sensitive to vancomycin, linezolid and rifampicin.

ObjectiveTo investigate the modulating effect of modified Wumeiwan （MWMW） on the ulcerative colitis （UC）-associated intestinal helper T cell 17 （Th17）/regulatory T cell （Treg） balance and intestinal flora by using a human flora-associated model of UC patients with dampness-heat obstruction syndrome， thus providing a new idea for the UC-related research and therapeutic strategies. MethodsThe 24 male C57BL/6J mice were randomized into normal control， model， and MWMW groups （n=8）. Model and MWMW groups were first treated with an antibiotic cocktail （vancomycin， 0.1 g·kg^-1； neomycin sulfate， 0.2 g·kg^-1； ampicillin， 0.2 g·kg^-1； metronidazole， 0.2 g·kg^-1） for 21 days. At the end of antibiotic treatment， the gavage of fecal microbiota suspension from UC patients with dampness-heat obstruction syndrome was started at a dose of 0.2 mL·d^-1 for 19 consecutive days， by which a human flora-associated model of UC was obtained. The MWMW group was administrated daily with MWMW liquid （12.5 g·kg^-1）， while the normal control and model groups were administrated by gavage with an equal amount of sterile water for 7 consecutive days. The symptoms of dampness-heat obstruction were observed. The colon length and spleen index were measured and calculated， and the proportions of Th17 and Treg cells were detected by flow assay. The intestinal flora was analyzed by 16S rRNA high-throughput sequencing. ResultsCompared with the normal control group， the model group showed shortened colon （P<0.05） and increased spleen index （P<0.01）. Compared with the model group， the MWMW group showed prolonged colon （P<0.01） and decreased spleen index （P<0.05）. After the intervention of MWMW， the Th17 proportion and Th17/Treg ratio in the colon decreased （P<0.01）， and the proportion of Treg cells increased （P<0.05）. The number of species and alpha and beta diversity of intestinal flora in mice were regulated by MWMW （P<0.05）. In terms of intestinal flora composition， MWMW increased the relative abundance of several phyla （Firmicutes， Proteobacteria， Fusobacteriota， Actinobacteriota， and Gemmatimonadota）， the genus Bacteroides， and two species （Bacteroides thetaiotaomicron and B. fragilis） in model mice. Moreover， Spearman's correlation analysis showed that the relative abundance of B. thetaiotaomicron and B. fragilis were negatively correlated with the Th17 level （P<0.05）. In addition， the above changes in intestinal flora caused the changes in microbial genes involved in 14 pathways， such as glycolysis， amino acid degradation， inorganic nutrient metabolism， biosynthesis of pyrimidine deoxyribonucleotides， antibiotic resistance， and degradation of polysaccharides. ConclusionsThe human flora-associated model successfully simulated the changes （marked by a decrease in the abundance of Bacteroides） of intestinal flora in UC patients with dampness-heat obstruction syndrome. MWMW can enrich the abundance of beneficial bacteria such as B. thetaiotaomicron and B. fragilis and promote the synergistic intestinal immune modulation with the metabolic functions centered on glycolysis， amino acid metabolism， and nucleotide synthesis through bacterial polysaccharide utilization sites to reduce the Th17/Treg ratio， thereby exerting a protective effect on UC.
