ObjectiveTo investigate the effect and mechanism of modified Sini San in ameliorating intestinal mucosal barrier by observing its effects on short chain fatty acids （SCFAs） and high mobility group protein B1 （HMGB1）/receptor of advanced glycation end products （RAGE） signaling pathways in chronic stress rats. MethodsThe 50 male SD rats were randomly divided into control group，model group，low-dose modified Sini San group （7.34 g·kg^-1·d^-1），high-dose modified Sini San group （14.68 g·kg^-1·d^-1），and Fructo-oligosaccharides group （3.15 g·kg^-1·d^-1），with 10 rats in each group. Except for the control group，all other groups were subjected to chronic unpredictable stress/social isolation to create a chronic stress model for 6 weeks. After 4 weeks of modeling，each treatment group was given corresponding drugs by gavage for 2 weeks while modeling. The control group and model group were given the same volume of physiological saline. The effects of Modified Sini San on behaviors，body weight，Bristol score in feces and fecal moisture content in chronic stress rats were observed. Hematoxylin and eosin （HE） staining was used to observe the pathological changes in the cecum. The content of SCFAs in the cecal contents of rats were detected by Gas chromatography-mass spectrometry （GC-MS）. Immunohistochemistry and Western blot were used to detect the expression of HMGB1/RAGE pathway related proteins in cecal tissue. The levels of ZO-1，Occludin，and Claudin-1 in the cecal tissue were detected by enzyme linked immunosorbent assay （ELISA）. ResultsCompared with the model group，the sucrose preference rate，total distance traveled and the number of grid crossings in the open field test of rats in the low-dose modified Sini San group were obviously increased （P<0.05， P<0.01），and the immobility time in the open field test and the immobility time in the forced swimming test of rats in the low-dose and high-dose modified Sini San groups were obviously reduced （P<0.05， P<0.01）. Meanwhile，the Bristol score and fecal moisture content of rats in the low and high dose groups of modified Sini San were obviously increased （P<0.05）. The low-dose group of modified Sini San had intact mucosal layer structure in the cecal tissue and reduced infiltration of inflammatory cells. The content of SCFAs in the cecal contents increased，with a obviously increase in the content of acetic acid，propionic acid，butyric acid，and isovaleric acid （P<0.05， P<0.01） and the expression levels of HMGB1，RAGE，Toll-like receptor 2（TLR2），Toll-like receptor 4（TLR4），tumor necrosis factor-α（TNF-α），and nuclear factor kappa-B p65（NF-κB p65） proteins in cecal tissue were significantly decreased （P<0.05， P<0.01） in low-dose group of modified Sini San. Meanwhile，the contents of ZO-1，Occludin，and Claudin-1 in the cecal tissue were obviously increased （P<0.01） in low-dose group of modified Sini San. ConclusionModified Sini San can improve the function of intestinal mucosal barrier in chronic stress rats by increasing the content of SCFAs in the intestine and inhibiting the HMGB1/RAGE pathway.

This article summarized the clinical experience of MEI Guoqiang in treating lung cancer of phlegm-heat obstructed in the lung syndrome with modified Xiaoxianxiong Decoction （小陷胸汤）. It is believed that the key pathogenesis of lung cancer with phlegm-heat obstructed in the lung syndrome is the phlegm-heat toxin accumulation. According to the different pathogenic effects of qi stagnation， blood stasis， pathogenic toxin， phlegm-damp， qi deficiency， yin deficiency in the occurrence and development of the disease， it is advocated to clear heat and resolve phlegm， and additionally the methods of diffusing the lung and relieving cough， resolving toxins and dissipating masses， rectifying qi and activating blood， dispelling dampness， supplementing and boosting qi and yin are used if necessary. Multiple methods are used together and flexibly matched. In clinical practice， Xiaoxian-xiong Decoction with the function of clearing heat and relieving phlegm is recommended as the basic formula for further modification. For patients with mild lung symptoms， modified Xiaoxianxiong Decoction is commonly used， while for those with obvious symptoms， self-made Maxing Xianxiong Decoction（麻杏陷胸汤） in modifications is suggested. For patients with Shaoyang （少阳） diseases， modified Chaihu Xianxiong Decoction （柴胡陷胸汤） is often used.

According to related literature on the treatment of functional dyspepsia by the combination of syndrome differentiation of traditional Chinese medicine and western medicine in recent years, the general rule was summerized. In this paper, the relevant literature was summarized from the traditional Chinese medicine on disease, etiology and pathogenesis, syndrome differentiation and clinical treatment of functional dyspepsia.

OBJECTIVETo use a lectin microarray to study the alteration of glycan affinity profiles of serum glycoproteins during the hepatitis B e antigen (HBeAg) and hepatitis B surface antigen (HBsAg) seroconversion in patients with chronic hepatitis B (CHB) following treatment with antiviral therapy,and to explore its biological significance.

METHODSCHB patients were divided into the following four groups:untreated HBeAg-positive,HBeAg seroconversion after anti-HBV therapy,HBsAg loss after anti-HBV therapy,and healthy individuals (controls).Serum samples were collected from each participant,depleted of high abundance proteins and analyzed by a lectin microarray containing 50 lectins.The lectin-affinity glycan profiles of serum proteins were partially verified by lectin blotting.Between-group differences were analyzed by one-way analysis of variance,and pairwise comparisons were carried out with the Student-Newman-Keuls (SNK) method.

RESULTSThe results from the lectin microarray and lectin blotting assay showed significantly reduced affinity for 16 lectins in the untreated HBeAg-positive group compared to the control group (P less than 0.05);in addition,the specific glycan profiles of the untreated HBeAg-positive group included decreased terminal and core fructose,GalNAc alpha-Thr/Ser (T,Tn-antigen),GalNac alpha,terminal beta1-4,and beta-D galactose,bisecting and/or GlcNAc,mannose and Sia.However,the HBeAg seroconversion after anti-HBV therapy group showed enhanced binding of PSA,MPL and the above-mentioned 16 lectins (P less than 0.05),suggesting that the reduced serum glycoprotein glycan structures returned to normal or slightly higher than healthy levels after the therapy-induced seroconversion.Comparison of the group with HBsAg loss after anti-HBV therapy to the group with HBeAg seroconversion after anti-HBV therapy showed the binding ability of ten lectins (AAL,ACL,HAL,HPL,RCA-I,LEL,STL,PHA-E,NML and PCL) were weakened to near control levels and six lectins (VAL,LCA,GNL,PSA,MPL and JAC) were significantly strengthened (all P less than 0.05). These findings implied that the glycan containing terminal fructose, GalNacalpha, terminal beta1-4 galactose,and bisecting GlcNAc glycan structures dropped to near control levels, while the terminal beta-D-galactose residues and core fructose structure increased significantly.

CONCLUSIONThe glycan structures of serum glycoproteins are closely related to HBeAg and HBsAg seroconversion in CHB patients.It is possible that a special lectin binding glycan involving the terminal beta-D-galactose residues and core fructose may act as sugar markers associated with the disappearance of serum HBsAg during anti-HBV therapy for CHB.
