Anti-influenza properties of herbal extract of Althaea rosea in mice / 대한수의학회지

Althaea rosea has been used in traditional Chinese medicine to treat numerous diseases, but no studies have investigated its anti-influenza properties to date. In this study, we investigated the anti-influenza effects of Althaea rosea. BALB/c mice orally pretreated with Althaea rosea (200 µL, 0.1 mg/mL concentration in phosphate-buffered saline) and followed by infection of influenza A virus nasally showed higher survivability and lower lung virus titer against divergent subtypes of influenza A virus infection. We also found that oral administration of Althaea rosea elicited antiviral innate immune responses in serum, bronchoalveolar lavage fluid, small intestinal fluid, and the lungs. Taken together, these findings suggest that aqueous extracts of Althaea rosea are a potential candidate for use as an anti-influenza drug.

Study on the correlation of interferon induced virus-related genes and the clinical features of patients with systemic lupus erythematosus / 中华风湿病学杂志

Objective To investigate the expression of the genes correlated with interferon induced genes virus (MX1, OAS1, IFI44) in the peripheral blood leukocytes of patients with systemic lupus erythematosus (SLE), and to evaluate the relationships between the expression levels of these genes and diseaseactivity. Methods The clinical data of 100 SLE patients, 40 non-SLE patients with rheumatic diseases, and 40 normal controls were collected. Peripheral blood samples were collected. Total RNA was extracted and transcribed into cDNA. SYBR green dye based real-time quantitative PCR method was used to compare the expression levels (indicated as △CT value) of MX1, OAS1 and IFI44 in patients with SLE and those in the controls. Comparisons between groups were performed with ANOVA and Spearman correlations. Results ①The △CT value of MX1, OAS1 and IFI44 expression level of the SLE patients (3.4±1.8, 4.2±1.5, 8.8±2.2)was significantly higher than those of the non-SLE patients (2.4±0.4, 3.4±0.7, 5.4±2.1 ) and normal controls (2.3±1.1, 2.6±0.7, 5.2±2.0). ② The △CT value of OAS1 and IFI44 expression level of the SLE patients in severe disease was significantly higher than those of the SLE patients in mild disease and the SLE patients with stable disease. ③The ACT value of OASI and IFI44 were correlated with the SLEDAI scores (r=0.038,0.380). ④ The △CT values of MX1, OAS1 and IFI44 expression level of the SLE patients with arthritis were significantly higher than those of SLE patients without arthritis. ⑤ The △CT value of IFI44 expression level of the SLE patients with lupus nephritis (3.2±2.1,2.2±1.1) was significantly higher than that of the SLE patients without lupus nephritis. ⑥ There was correlations among these genes in SLE patients (P＜0.05). Conclusion The value of MX1, OAS1 and FFF44 expression level of SLE patients is up-regulated. The real time expression levels of OAS1, IFI44 genes are associated with SLE disease activity and there are close correlation among these genes with interferon induce virus-relationed genes (MX1, OAS1, IFI44) in SLE patients.

Tratamento do papiloma vírus humano na infância com creme de imiquimode a 5 por cento / Treatment of human papillomavirus in childhood with imiquimod 5 percent cream

Lesões decorrentes da infecção pelo papilomavírus humano na infância, em especial as verrugas anogenitais, são um importante problema epidemiológico e terapêutico. O tratamento das verrugas anogenitais na infância é um desafio terapêutico. Os tratamentos convencionais geralmente são dolorosos e necessitam de anestesia geral. O imiquimode, um imunomodulador tópico, constitui uma alternativa terapêutica. Serão descritos quatro casos tratados com sucesso utilizando creme de imiquimode a 5 por cento aplicado topicamente.

In children, lesions caused by the human papillomavirus (HPV) constitute a significant epidemiological issue and a therapeutic dilemma, particularly in the case of anogenital warts. The treatment of anogenital warts in children is a challenge, since standard treatments are generally painful and require the patient to be anesthetized. Imiquimod, a topical immune response modifier, constitutes an alternative therapeutic agent for the treatment of HPV. The present report describes four cases in which treatment with topically applied imiquimod 5 percent cream was implemented with successful results.

Treatment of herpes simplex keratitis with combination of poly Ⅰ: C, Vitamine C and a small dose of dexamethasone / 眼科

44 eyes (42 patients) of HSV keratitis were treated by a combined injection of poly Ⅰ: C, vitamine C and a small dose of dexamethasone with satisfactory results. 22 (88％) of 25 eyes of the superficial type were cured and 2 eyes(8％) improved; 13 (68.4％) of 19 eyes of the deep stromal type were cured and 3 eyes (15.8％) improved. The average therapeutic course was 13.6 days for the superficial type and 25.4 days for the deep stromal type. 4 eyes (19.1％) recurred during a follow-up of 6-22 months. The mechanism of curative effects and the significance of the small does of dexamethasone were discussed.
