Objective To detect beta-human papilloma virus (HPV) and determine its genotype in actinic keratosis (AK) lesions.Methods Tissue specimens were collected from the lesions of 39 patients with AK and normal skin of 40 healthy controls.A nested PCR was performed to detect alpha-HPV and beta-HPV DNA in these specimens.The genotype of beta-HPV was determined in beta-HPV DNA-positive specimens by a common PCR using specific primers targeting 12 HPV genotypes,including HPV 5,8,15,17,19,20,21,23,36,38,49 and 80.Results The detection rate of beta-HPV DNA was 84.6％ (30/39) in the patients with AK,and 30.0％ (12/40) in the healthy controls (x2 =6.76,P ＜ 0.05),while no significant difference was observed in the detection rate of alpha-HPV DNA between the two groups (12.8％ vs.7.5％,x2 =0.91,P ＞ 0.05).HPV 38 was the predominant genotype of beta-HPV in these patients with a detection rate of 36％ (12/33),followed by HPV36.The prevalence of all the 12 genotypes of HPV was consistently low in the healthy controls.Mixed HPV infections were observed in 10 AK lesions,but in none of the healthy controls.No statistical difference was noted in the positivity rate of beta-HPV among patients at different ages,of different genders,with different occupations or clinical courses (x2 =0.53,0.94,0.81,0.73,respectively,all P ＞ 0.05).Conclusions Compared with healthy controls,the patients with AK showed a higher beta-HPV infection rate,with HPV38 as the predominant genotype.

ObjectiveTo observe the lung injury of rats caused by PM2.5 induced imbalance of TH17/Treg immune system and the intervention effect of two different TCM treatments.Methods Wistar male rats were randomly divided into normal group, model group, TCM-treated group1 and TCM-treated group 2. PM2.5-induced lung injury model was established by airway instillation. Model group was given normal saline for gavage. TCM- treated group 1 and 2 were given Yupingfeng Powder and Guomin Decoction combined with Zhisou Powder for gavage. The pathological changes of bronchial and lung tissues, the contents of IL-8, IL-10, IL-17, NE, and MUC5AC in serum and BALF were compared, and the expressions of Foxp3 and IL-17 in lung tissue of each group were analyzed.Results Compared with normal group, the contents of IL-8, IL-17, NE and MUC5AC in serum and BALF of model group increased significantly, while IL-10 decreased significantly (P<0.05,P<0.01); the expression of IL-17 increased significantly and the expression of Foxp3 decreased significantly in lung tissue (P<0.01). Compared with model group, the contents of IL-8, IL-17, and NE decreased in TCM-treated group 1 and 2, while the content of BALF IL-10 increased significantly (P<0.05). The content of IL-10 in serum increased significantly in TCM-treated group 2 (P<0.05); the protein expression of IL-17 of lung issue decreased significantly, and the protein expression of Foxp3 increased significantly (P<0.01). The pathological changes were improved significantly.Conclusion PM2.5 can induce lung injury caused by the imbalance of TH17/Treg. Both two treatments can significantly improve the lung injury induced by PM2.5 and the imbalance of TH17/Tregs immune system.

Objective To study the process conditions of purifying the total flavonoids from Cacumen Platycladi by AB-8 resin. Methods Spectrophotometric method was used to detect the total flavonoids,and HPLC was used to determine quercitrin and analyze the characteristic peaks of Fingerprint. Results The purification effect was satisfactory when the concentration of original solution of the extract of Cacumen Platycladi was 0.20 g?mL-1,the loading amount was 0.375 g of Cacumen Platycladi per 1 mL of wet AB-8 resin,the adsorption velocity was 1 mL?min-1,the eluant was 70 %alcohol being 4 times as much as the resin volume,and the elution velocity was 2 mL?min-1. AB-8 resin could be used for 3 times repeatedly after being reproduced by 95 %of ethanol and 1 moL?L-1 of natrium hydroxydatum (NaOH). The remaining rate of the total flavonoids and quercitrin was over 70 %and 95 %respectively,and the remaining rate of peaks 1～3 was over 90 %. After being purified by the B-8 resin,the contents of the total flavonoids and quercitrin were raised 2.48 times and 3.29 times more than those before purification respectively. Conclusion AB-8 resin is fit for separating and purifying the total flavonoids from Cacumen Platycladi.
