This articles summarized the clinical experience of national TCM master Professor Yan Shiyun in using ointment prescriptions to treat chronic pharyngitis.Professor Yan Shiyun believes that the etiology and pathogenesis of chronic pharyngitis are based on inflammation of the deficiency fire,with phlegm heat accumulation as the symptoms.Dysfunction of organs such as the liver,gallbladder,spleen and stomach,lungs and kidneys,as well as retention of wind pathogens,are also important pathological mechanisms.Based on the differentiation of Tibetan symptoms,the clinical approach advocates for a comprehensive understanding of the patients'condition,focusing on the core pathogenesis.The main treatment methods include regulating yin and yang,clearing phlegm and heat,regulating spleen and stomach,dispelling wind and clearing throat,and comprehensively considering other syndromes.The use of compound prescriptions for comprehensive treatment has shown significant therapeutic effects.The commonly used medicinal combination is Physalis Calyx Seu Fructus,Chebulae Fructus Immaturus and Arctii Fructus.

Hepatitis B surface antigen (HBsAg) carrying preS sequences could be an ideal candidate for a new hepatitis B virus (HBV) vaccine with higher efficacy. Here we report the success in achieving efficient and stable expression of hepatitis B virus S antigen and preS1 epitope fusion protein (S/preS1) in CHO cells. The HMRCHEF53u/Neo-S/preS1 expression vector carrying S/preS1 gene was constructed and transfected into CHO-S cells. A stable and high-expression CHO cell line, named 10G6, was selected by ELISA and limiting dilution analysis. Western blotting analysis showed S/preS1 expressed from 10G6 cells possessed both S and preS1 antigenicity. 10G6 cells displayed characters of favorable growth and stable S/preS1 expression in repeated batch cultures as evaluated by viable cell density, viability and S/preS1 concentration. And cultivation of 10G6 cells in fed-batch mode resulted in S/preS1 production at 17-20 mg/L with viable cell density at 7 x 10(6)-10 x 10(6) cells/mL.
