四川省人感染猪链球菌病潜伏期分析

目的探索人感染猪链球菌病潜伏期、感染方式与发病的关系,为人感染猪链球菌病防治提供科学依据。方法对个案病例调查中的暴露时间、感染途径、手部是否受伤、发病时间等进行分类整理和统计分析。结果180个病例发病前均有接触病死猪史,主要是屠宰,潜伏期3.5h～9d中位数为2d,参与宰杀者潜伏期短于洗切加工者,其他感染途径者潜伏期最长;手部有明显外伤者其潜伏期短于无外伤病例。结论切断人与病死猪的直接接触是控制人感染猪链球菌病的最佳途径。

Anti-inflammatory effects of Pulvis Fellis Suis extract in mice with ulcerative colitis

Ethnopharmacological relevance

Pulvis Fellis Suis is used in folk medicines to treat intestinal diseases, acute pharyngitis, whooping cough and asthma in China. Although several reports indicate that Pulvis Fellis Suis display diverse biological activities, such as antibacterial, anti-inflammatory and anti-infusorian effects, its effects on ulcerative colitis have not been previously explored.

Aim of the study

The purpose of the present study is to assess the anti-inflammatory effect of Pulvis Fellis Suis (PFS) extract in acute ulcerative colitis model induced by trinitrobenzene sulfonic acid (TNBS) in mice.

Materials and methods

Different doses of Pulvis Fellis Suis extract (100, 200 and 400 mg/kg/day) and sulfasalazine (500 mg/kg/day) were administered by gavage for 7 days after the induction of colitis with TNBS. The efficacy of PFS was studied by macroscopical and histological scoring systems as well as myeloperoxidase (MPO) activity. Serum levels, including tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were assayed by enzyme-linked immunoassay. The expression of cyclooxygenase (COX)-2 in the colons was assessed by immunohistochemical analysis.

Results

Treatment with PFS significantly attenuated macroscopic damage as compared with TNBS (P < 0.01). Histological analysis showed that PFS improved the microscopic structure and preserved some areas of the colonic mucosa structure. In addition, administration of PFS effectively inhibited COX-2 protein expression and MPO activity accumulation. TNF-α and IL-6 levels were also diminished dose-dependently (P < 0.05, P < 0.01), and IL-6 level obtained had no significant results by small dose of PFS. All the effects of these parameters were comparable to that of the standard sulfasalazine, especially at the highest dose level.

Conclusions

We have shown for the first time that PFS has an anti-inflammatory effect in TNBS-induced ulcerative colitis which might be related to the reduction of up-regulated TNF-α and IL-6 production, and that it may have therapeutic value in the setting of inflammatory bowel disease (IBD).     

12例人感染猪链球菌病患者的护理

目的：探讨人感染猪链球菌病患者的护理评估和有效的护理措施。方法：回顾12例人感染猪链球菌病患者的临床资料,总结分析其护理措施及其预后。结果：对不同类型的患者进行积极治疗和有效的护理措施后,10例发热患者平均约1周体温恢复正常,4例头昏、头痛症状消失,4例瘀斑、瘀点消退,1例听力恢复,1例口周疱疹消退,1例并发多器官功能衰竭死亡,1例放弃治疗;均无护理并发症发生。结论：做好护理评估（重点询问流行病学史）、并加强消毒隔离、一般护理、病情观察、症状护理、心理护理及其健康教育指导等护理措施,对提高本病治愈率、减少并发症非常重要。
