Evaluation of the permeability mainly focuses on intestinal absorption in biopharmaceutics classification system (BCS). It is more complicated that the absorption and metabolism under multicomponent environment in biopharmaceutics classification system of Chinese materia medica (CMMBCS) compared with single component environment, which needs suitable mathematical models to be described. Therefore, with full consideration of existing single component mathematical algorithm combining with the characteristics of intestinal absorption and metabolism, we explored and designed a new mathematical algorithm of intestinal absorption and metabolism of multicomponent drug. Then we put forward a new coefficient, P (influence), the relative change rate of the single component's intestinal absorption and metabolism under multicomponent environment compared with single component environment, which described the influences of intestinal absorption and metabolism of the component under multicomponent environment. Moreover, P (influence) highlights the distinctive characteristics of multicomponent drug's intestinal absorption and metabolism, and lays the foundation for the construction of CMMBCS.

The prescription combinations of traditional Chinese medicine (TCM) focuses on the taste and channel tropism, the Qi movement, as well as the compatibility according to multiple combination principles and medicinal property and flavor combination of several traditional Chinese medicines. With the in-depth study on the prescription compatibility, researchers have realized that the medicinal property theory is the core of TCM combinations. However, there is no definite method for combinations based on medicinal properties. In this paper, the authors put forward an method for designing prescription combinations based on bipartite graph and the greedy algorithm. With the medicinal property combinations of Siweilurong Pills for example, the authors proved this method could provide ideas for quickly choosing herbal medicines for prescription combinations, and discussed the prospect of this method in substituting previous and endangered herbal medicines and banned medicinal materials.

Objective To investigate the effects of enteral nutrition with galactooligosaccharides (GOS) on serum inflammatory cytokines in rats with severe acute pancreatitis (SAP). Methods SD rats were randomly divided into sham operation control group, SAP with enteral nutrition (EN) group and SAP with EN supplemented with GOS (GOS-EN) group, and each group was divided into 4 d and 7 d subgroups according to the time that animals were sacrificed (n=8 in each subgroup). Rat SAP models were established by injection of 38 g/L sodium taurocholate beneath the pancreatic capsule. The serum amylase, inflammatory cytokines TNF-α, IL-2 and IL-10 were detected. Results At each time point, the levels of serum amylase in all SAP groups were significantly higher than those in sham operation control group (P < 0.01), and the levels in GOS-EN group were significantly lower than those in EN group (P < 0.01). The levels of serum TNF-α and IL-10 in all SAP groups were significantly higher than those in sham operation control group (P < 0.01), while the levels of IL-2 in all SAP groups were significantly lower than those in sham operation control group. The levels of TNF-α in GOS-EN group were significantly lower than those in EN group (P <0.05), while the levels of IL-2 and IL-10 and the ratio of IL-10/TNF-α were significantly higher than those in GOS-EN group (P < 0.05). Conclusion Early EN supplemented with GOS could modulate the balance of pro- and anti-inflammatory response.

Objective To investigate the expression and significance of tumor necorisis factor related apoptosis induled ligand receptor(TRAILR) in human craniopharyngioma.Methods The expression of TRAILR was determined by immunohistochemistry and in situ hybridization in 24 samples of craniopharyngioma and 16 samples of normal brain tissue.Results With low decoy receptor(DcR) expression in partial craniopharyngioma cells and low death receptor(DR) expression in partial normal brain cells,DR was expressed highly in all craniopharyngioma samples while DcR in most normal brain tissue. High DR expression and low DcR expression in craniopharyngioma tissue differed from low DR expression and high DcR expression in normal brain tissue(P

Objective To investigate the prevalence of clonorchiasis among residents of Huachuan Country,Heilongjiang Province and to provide a basis for development of control strategies.Methods From 2011 to 2012,cluster random sampling was performed to survey the incidence of clonorchiasis in Huachuan Country.Fecal specimens were collected and examined the clonorchis sinensis eggs by Kato-Katz method.A questionnaire survey was conducted to collect related information such as age,gender,occupation and eating habits.The infection characteristic was analyzed.Results Totally 884 patients with clonorchiasis were found among 2248 residents,and the infection rate was 39.32％.The infection rate in male[47.15％(611/1296)] was significantly higher than females [28.68％(273/952),x2 =34.55,P ＜ 0.01].The infection rate increased with age,which was higher in the 20-69 years old people,with the highest infection rate in the 50-59 years old groups[45.34％ (219/483)].Of the occupational distribution,farmers had the highest infection rate [47.24％ (420/889)],followed by cadres and staffs[38.38％(190/495)].Of residents with fresh fish eating history,the prevalence of clonorchiasis was 53.38％(150/281).Conclusions The prevalence of clonorchiasis is still high in Huachuan County.To reduce the prevalence of clonorchiasis,comprehensive prevention measures,health education and group chemotherapy should be carried out.

Objective To observe the incidence and explore the potential factors of nonresponse to cardiac resynchronization therapy (CRT) in patients with severe chronic congestive heart failure. Method CRT was performed in 119 patients with NYHA function class Ⅲ - Ⅳ and left ventricular ejection fraction ≤35% [96 men and 23 women, age (60.5 ± 11.3 ) years ]. Results Seven patients died for different reasons between 1 - 6 months post CRT and clinical and echocardiographic (Echo) data at 6 months post CRT were analyzed from the remaining 112 patients. The incidence of nonresponse to CRT was 28.57%.Compared to the response group, complete right bundle branch block, longer course of congestive heart failure, higher pulmonary systolic pressure and serum creatinine level and non-optimal target vessels positioning of the left venticle lead( the great cardiac vein and the middle cardiac vein)were the independent predictors for nonresponse after CRT( all P ＜ 0.05). Compared with nonresponse group, the dosages of digoxin and diuretics used for heart failure were significantly reduced in response group ( P ＜ 0.01 ).Conclusions The incidence of nonresponse after CRT was 28.57% in this patient cohort Higher pulmonary systolic pressure and serum creatinine level and non-optimal target vessels positioning of the left venticle lead ( the great cardiac vein and the middle cardiac vein) were the independent predictors for nonresponse after CRT.

The purpose of this work was to investigate the effects of niflumic acid (NFA), a chloride channel blocker, on the proliferation of human hepatoma cell line (HHCC). Cell proliferation was analyzed by cell count and MTT assay. Cell cycle analysis was carried out by flow cytometry. [Ca(2+)](i) was determined by laser scanning confocal system. It was found that NFA decreased significantly the cell number and the MTT optical density (OD) of HHCC cells, and that the OD value was reversed after washout of NFA. Compared with control, NFA blocked cell cycle progression in G(1) phase. Extracellular application of NFA (100 micromol/L) induced a rapid decrease in [Ca(2+)](i). These findings demonstrate that blockage of chloride channels by NFA induces growth arrest of HHCC in G(1) phase, which may be due to the inhibition of Ca(2+)/CaM-dependent signaling pathways.

Currently, the herbal prescription therapy for corresponding constitutional diseases is a common constitution regulating method. This method has an obvious effect in treating and regulating constitution-related diseases. However, for people who do not have disease, they prefer to regulate constitution with dietary therapy. In this paper, the researchers came up with a design method of constitution regulating and healthcare foods based on medicinal property combination mode of clinical empirical formulas. With "Yupinfeng San", a common formula for Qi-insufficiency constitution and specific endowment constitution, as the example for constitution regulating and healthcare foods, the researchers proved the effectiveness and rationality of healthcare food schemes in terms of the efficacy of single herb and the modern pharmacological study.
