??Objective    To discuss the influence of basic periodontal therapy on the level of IL-8?? IL-10 in serum and gingival crevicular fluid in patients who have chronic periodontitis complicated by coronary heart disease. Methods     A total of 65 cases of patients with chronic periodontitis complicated by coronary heart disease were selected and divided into two groups randomly??Group A of 35 patients who received the basic periodontal therapy and cardiac medical treatment??Group B of 30 patients who received cardiological treatment only. Then??select 25 patient who had developed chronic severe periodontitis with non-systematic disease to establish group C and give them the basic periodontal therapy only. Observe the changes of the IL-8??IL-10 levels in serum and gingival crevicular fluid and the periodontal infection indexes??BI??PD??. Results    The results showed that after three months of basic periodontal therapy the periodontal clinical indices of both group A and group C became better and the IL-8 level obviously reduced??while the IL-10 level obviously increased. There was no obvious difference between group A and group B in each examination index before the therapy. After three months??we found that the periodontal infection index??SBI PD??of group A was obviously better than group B. Compared to group B??the IL-8 level of group A obviously reduced??and the IL-10 level obviously increased. The difference was statistically significant??P < 0.05??. Conclusion    The basic periodontal therapy can effectively improve periodontal conditions of the patients with chronic periodontal diseases??and reduce the risk of breaking the normal cardiovascular function.

运用胰门板降低技术取出嵌顿于胰腺段胆总管的巨大结石

目的 探讨胰门板降低技术处理胰腺段胆总管巨大结石的应用价值。方法 回顾性分析上海交通大学医学院附属仁济医院近期收治的1 例利用胰门板降低技术取出胰腺段胆总管巨大结石的患者临床资料，并复习文献资料。结果 该例患者胰腺段胆总管内嵌顿一颗直径约2.5 cm质硬结石，纵行切开十二指肠上段胆总管前壁后采用液电碎石仪和取石钳难以碎石和取石，最终笔者首次利用胰门板降低技术显露胰腺段胆总管前壁后，继续纵行切开胰腺段胆总管才取出结石。术后经抗感染、补液等对症支持治疗痊愈出院，随访1 年半无结石复发和胆管狭窄。结论 胰门板降低技术可安全显露胰腺段胆总管，有助于取出胰腺段胆总管内嵌顿结石。     

鼻内镜术后鱼腥草滴鼻液与糠酸莫米松鼻喷雾剂联合局部应用对鼻黏膜组织重塑的影响研究

目的　探讨鼻内镜术后鱼腥草滴鼻液与糠酸莫米松鼻喷雾剂联合局部应用对黏膜组织修复与重塑的影响。方法　将46例行鼻内镜手术的慢性鼻-鼻窦炎伴和不伴鼻息肉患者，通过随机数表随机分为3组，分别为鱼腥草滴鼻液+糠酸莫米松鼻喷联合治疗组（16例）、单用糠酸莫米松鼻喷雾剂组（15例）及单用鱼腥草滴鼻液组（15例），在鼻内镜术后给予相应治疗，3个月后评估患者术后治疗有效率情况。采用免疫组化法评估鼻黏膜上皮细胞损伤分级，并分别计数鼻黏膜上皮细胞中转化生长因子β1（transforming growth factor-β1，TGF-β1）、成纤维细胞生长因子-2（fibroblast growth factor-2，FGF-2）、基质金属蛋白酶-9（matrix metalloproteinase-9，MMP-9）阳性细胞数。结果　治疗3个月后，联合治疗组患者治疗后的病情完全控制率优于单药治疗组（P 均<0.05），联合治疗组患者中无鼻黏膜损伤比例显著高于单药治疗组，且基底膜厚度较单药治疗组薄，TGF-β1阳性细胞数较单药治疗组少（P 均<0.05）。治疗后联合治疗组鼻黏膜上皮细胞中FGF-2阳性细胞数和MMP-9阳性细胞数较单药治疗组明显减少（P 均<0.05）。结论　鼻内镜术后鱼腥草滴鼻液与糠酸莫米松鼻喷雾剂联合局部应用，较局部单用以上两种药物有更好疗效，可促进黏膜上皮化，能明显减缓鼻黏膜重塑过程的发生与发展，促进鼻黏膜功能恢复，对鼻内镜术后鼻黏膜修复及预后具有积极意义。     

基于LC-MS的甘草炮制雷公藤降低肝毒性的代谢组学研究

目的 观察甘草炮制雷公藤Tripterygium wilfordii后对小鼠血清中代谢产物的影响，初步探讨其降低肝毒性的可能代谢通路。方法 将C57BL/6小鼠随机分为对照（Con）组、雷公藤（Raw）组、甘草炮制雷公藤（Pro）组，观察小鼠肝组织病理变化，检测小鼠肝功能生化指标、炎症因子水平；利用液质联用（LC-MS）技术结合代谢组学方法，对各组间的代谢差异进行表征。结果 与Raw组相比，Pro组小鼠肝组织损伤显著改善，肝功能生化指标、炎症因子水平显著降低，表明甘草炮制雷公藤后可以降低小鼠肝毒性；共筛选出脂肪酸、磷脂酸、甘油酯、磷脂酰胆碱、胆酸等12个潜在生物标志物，主要涉及脂肪酸生物合成、甘油磷脂代谢、花生四烯酸代谢等9个代谢通路。结论 甘草炮制雷公藤可有效降低小鼠的肝毒性，其机制可能与调节脂肪酸代谢等通路相关，为其临床合理应用提供参考依据。
