Objective To prepare the pH-dependent Yuchangning Tablet for colon-specific delivery(PYTCSD) used in treating the ulcerative colitis and evaluating the releasing property in vivo and in vitro.Methods The coating prescription was screened by the in vitro delivery of matrine and oxymatrine.The in vitro releasing property of the preparation was examined by the method of in vitro delivery. The in vivo releasing property of the preparation was evaluated by the shadowgraph technique of barium sulfate.Results The preparation method of the PYTCSD was obtained.The core of the tablet was coated by the alcohol solution mixed with 3.70%(g/mL) Eudragit Ⅲ,0.37%(g/mL) DEP,and 0.93%(g/mL) talcum power.The weight of the core was increased 8%.From the in vitro delivery,matrine and oxymatrine were not detected in the simulated gastric fluid after 2 h.The quantities of matrine and oxymatrine were less 10% in the simulated intestinal fluid after 4 h.The quantities of matrine and oxymatrine were 86.5% and 86.8% in the simulated colon fluid after 1 h.On the basis of the in vivo delivery by treating eight volunteers,the PYTCSD could completely get to the ileocecum or ascending colon and disintegrate in that part.Conclusion The PYTCSD can be prepared and the preparation is significantly delivered in the specific colon.

Objective To investigate the effect of Rho kinase inhibitor,fasudil,on pulmonary fibrosis induced by paraquat in rats in order to elucidate the underlying mechanisms.Methods A total of 72 SpragueDawley male rats of specific pathogen free (SPF) were randomly (random number) divided into four groups:the normal control group (NS group,n =18),fasudil control group (FS control group,n =18),paraquat poisoning group (PQ poisoning group,n =18) and fasudil intervention group (FS intervention group,n =18).On days 7,14,28 after paraquat exposure,six rats were respectively selected from each group.These rats were anesthetized and sacrificed immediately,and their lung tissues were collected.The hydroxyproline (HYP) in the lung tissue was detected by using alkaline hydrolysis.The expressions of type Ⅰ,Ⅲ collagen protein,connective tissue growth factor (CTGF) and ROCK1 mRNA in Rho/ROCK signaling pathway were assayed by using the real-time quantitative PCR (RT-PCR),and the levels of type Ⅰ,Ⅲ collagen protein,connective tissue growth factor (CTGF) and Rho / ROCK signaling pathway ROCK1 protein were measured by using Western blotting.The pathological changes of lung tissue were observed under light microscope.Results There were no significant differences in the observed biomarkers between FS control group and NS group (P > 0.05).While in PQ poisoning group and FS intervention group on days 7,14,28 (all P < 0.05),the amount of HYP increased obviously (P < 0.05),the expressions of type Ⅰ,Ⅲ collagen protein,CTGF,ROCK1 mRNA and protein levels were increased significantly (P < 0.05).Compared with the PQ poisoning group,the amount of HYP decreased significantly,and the expressions of type Ⅰ,Ⅲ collagen protein,CTGF,ROCK1 mRNA and protein levels were decreased significantly in FS intervention group on days 7,14,28 (all P < 0.05).The pathological changes of lung tissue revealed that the degree of pulmonary fibrosis in the PQ poisoning group were most serious on 28 d after paraquat exposure,and the degree of pulmonary fibrosis were lessened in FS intervention group on days 7,14,28.Conclusions ROCK inhibitor,fasudil,has obvious therapeutic effects on paraquat-induced lung fibrosis,by regulating Rho / ROCK signaling pathway with downregulated expression of CTGF,and decrease in the levels of type Ⅰ,Ⅲ collagen protein,thus reducing protein deposition.

Objective To explore the epidemiology of different subgroups of respiratory syncytial virus (RSV) in hospi-talized children with acute respiratory infections in Suzhou. Methods RSV antigen in nasopharyngeal secretions specimens ob-tained from 42 208 hospitalized children with acute respiratory infections from January 2006 to December 2012 were detected using direct immunofluorescence assay. RT-PCR was used to differentiate subgroups A and B of RSV from the positive samples which were randomly selected in the epidemic season of different years. Results RSV infection had a seasonal trend. The peak season of RSV occurred between November and following year’s March and the detection rate of RSV was low between May and September. There was difference in RSV positive rates of peak seasons among different years from 2006 to 2012 (χ2=280.09,P<0.01). In 398 RSV antigen positive samples obtained from peak seasons of different years, 80.15%(319/398) were differentiated as subgroup A and 15.83%(63/398) were subgroup B except 16 samples (4.02%). There was significant difference in distribution of RSV subgroups in peak seasons among different years (P<0.01). Subgroup A of RSV was prevalent in most years. Both subgroup A and B were prevalent in peak season of 2008~2009 with lowest positive rate of RSV. In 2009~2010, subgroup B was prevalent. Conclusions From 2006 to 2012 in Suzhou area, the RSV detection rates in the first four prevalent seasons present an increase trend every other year and then sustain a high prevalence in the following two prevalent seasons. Subgroup A of RSV was the predominant pathogen in hospitalized children with acute respiratory infections.

AIM To determine the contents of arillanin A,tenuifoliside A and tenuifoliside C in raw Polygalae Radix (root barks),Polygalae Radix duramen,Glycyrrhizae Radix et Rhizoma-processed Polygalae Radix,waterboiling Polygalae Radix and honey-processed Polygalae Radix.METHODS The analyses of 50% methanol extracts from samples were performed on a 30 ℃ thermostatic Kromasil C18 column (250 mm ×4.6 mm,5 μm),with the mobile phase comprising of acetonitrile-0.1% formic acid flowing at 1.0 mL/min in a gradient elution manner,and the detection wavelength was set at 330 nm.RESULTS The contents of three oligosaccharide esters were the highest in raw Polygalae Radix,followed by those in honey-processed Polygalae Radix,and those in water-boiling Polygalae Radix were the lowest.These constituents also existed in Polygalae Radix duramen,but their contents were lower than those in root barks.CONCLUSION The ester bonds of oligosaccharide esters in Polygalae Radix may be hydrolyzed during processing,followed by the generation of small molecular organic acids.The medication of whole Polygalae Radix (root barks and duramen) can be taken into consideration in clinical practice to reduce toxicity and enhance efficacy.

AIM: A new HPLC-MS method was developed to determine finasteride in human plasma. METHODS: Two formulations of finasteride tablets were given to 20 healthy male volunteers according to a randomized 2-way cross-over design. The samples were extracted by ethyl acetate under basic conditions, then were separated by C18 column and determined by mass detector. RESULTS: The calibration curve of finasteride was linear and intra-day and inter-day RSD were less than 10 %. The pharmacokinetics parameters of the two formulations (4.5 ± 0.5) h for t1/2; (3.0 ± 0.7) and (2.8 ± 0.9) h for tmax, respectively. The results indicated that there was no significant difference on cmax, A UC0-24, t1/2 or tmax values between the two formulations. CONCLUTION: The relative bioavailability of tablets I with respect to tablets Ⅱ is (99.3 ± 9.2) % by the A UC0-24 measurement, and bioe quivalence is observed between the two tablets.

Different endophytes isolated from the seeds of Sophora flavescens were tested for their ability to produce matrine production. Response surface methodology (RSM) was applied to optimize the medium components for the endophytic fungus. Results indicated that endophyte Aspergillus terreus had the ability to produce matrine. The single factor tests demonstrated that potato starch was the best carbon source and the combination of peptone and NH₄NO₃ was the optimal nitrogen source for A. terreus. The model of RSM predicted to gain the maximal matrine production at 20.67 µg/L, when the potato starch was 160.68 g/L, peptone was 24.96 g/L and NH₄NO₃ was 2.11 g/L. When cultured in the optimal medium, the matrine yield was an average of 20.63 ± 0.11 µg/L, which was consistent with the model prediction. This study offered an alternative source for the matrine production by endophytic fungus fermentation and may have far-reaching prospect and value.
