The on-line monitor for the changes in the content of baicalin in Scutellariae Radix formula particles during the extraction process was conducted by using near infrared spectroscopy (NIR). High performance liquid chromatography (HPLC) was used as a reference method. Kennard-Stone (KS) was used to divide sample sets, so as to compare different pretreatment methods. The synergy interval partial least squares (SiPLS) was used to screen out modeling wave band to establish partial least-squares models. The relative error method was applied to predict forecast set samples of Scutellariae Radix in three extraction phases. The results showed that the model established by Savitzky-Golay smoothing with 11 points (SG11 points) was the best, with the root mean square with cross validation (RMSECV), root mean square error of correction (RMSEC) and root mean square error of prediction (RMSEP) of baicalin of 0.092 7, 0.134 4 and 0.114 8, respectively, the determination coefficient R2 of greater than 0.99, and the relative error of baicalin content of less than 5%. This indicates that the on-line near infrared reflectance spectroscopy could be applied in on-line monitor and quality control of the extraction process of Scutellariae Radix formula particles.

To investigate the role of immediate-early gene c-fos in sodium selenite-induced apoptosis and its position in a possible cascade of apoptogenic genes, we compared the time-courses of expression for 5 related genes, including c-fos, during the apop- tosis induced by sodium selenite with or without blockage of c-fos expression by adding c-fos antisense oligodeoxynucleotide ( ASO) in cultured cortical neurons. The results showed that: (1) in control experiments without c-fos ASO adding, 0. 5 μmol/ L sodium selenite-induced apoptosis as revealed by electrophoretic and flow cytometric examinations; at the same time, sodium selenite also induced down-regulation of bcl-2 mRNA expression and up-regulations of mRNAs related to bax, c-fos, p53, and acetylcholinesterase (AChE) genes; (2) in similar experimental conditions with c-fos ASO cotreatment, the sodium selenite-in- duced apoptosis was blocked with the up-regulation of p53 expression still emerging as before, while the changes in expressions of bcl-2, bax, AChE genes were reversed at the same time. The results suggest that c-fos ASO could play a protective role upon cortical neurons from suffering apoptosis induced by sodium selenite, and there might exist a cascade of gene expressions with p53 and c-fos genes being regulated upstream and then bcl-2, bax, and AChE genes being regulated downstream.

To propose a formula method of medicated diet based on medicinal property combination patterns in this paper under the context of lack of innovation in medicated diets. By analyzing the property combination patterns of traditional Chinese medicine and commonly used foods recorded in the pharmacopoeia, medicated diet formulae were optimized by using the greedy algorithm, with the property combination patterns of classical formulae based on the syndrome differentiation and treatment. In this paper, the Baihu Rensheng decoction, which is a classical formula for treating lung and stomach heat-derived diabetes, was taken for example in the formula design. As a result, totally 18 medicated diet formulae were developed and proved to be rational in the analysis on traditional Chinese medicines and nutriology. This method expands the way of thinking for personalized diet therapies and provides theoretical basis the industrial development and clinical application of medicated diets.

OBJECTIVETo observe the effect of Chinese herbal therapy on T-lymphocyte subsets in patients with IgA nephropathy (IgAN).

METHODSTotally 36 inpatients and outpatients at Department of Nephropathy, Xiyuan Hospital, China Academy of Chinese Medical Sciences, from June 2011 to June 2013 were recruited in the treatment group, while 20 volunteers were recruited as the healthy control group. Patients in the IgAN group only took Chinese herbal decoctions by syndrome typing for 3 months (except those accompanied with hypertension additionally took antihypertensive agents such as angiotensin-converting enzyme inhibitor and/or dihydropyridines calcium antagonist). No intervention was performed in the healthy control group. The values of Th1, Th2, and CD4+ CD25+ Treg, and red blood cell number in urine were detected using flow cytometry before and after treatment. 24 h urine protein was detected using inmmunoturbidimetry.

RESULTSCompared with the healthy control group, the CD4+ CD25+ Treg level obviously decreased in the IgAN group, showing statistical difference (P < 0.01). In the IgAN group, Th1, 24 h urine protein, and urine red blood cell counts were obviously lower after treatment, showing statistical difference when compared with before treatment (all P < 0.05).

CONCLUSIONChinese herbal therapy could reduce urine erythrocyte number and 24 h urine protein of IgAN patients, and down-regulating Th1 expression might be its mechanism.

Background Oxidative damage may cause the functional dysfunction and death of retinal vascular endothelial cells(RVECs),and further leads to the development of retinal vascular diseases.Fufang xueshuantong has a therapeutic effect on retinal vascular diseases,but little is known about its molecular mechanism.Objective The goal of this study was to investigate the protective effects and mechanism of fufang xueshuantong on injury of human RVECs induced by tert-butyl hydroperoxide(t-BHP).Methods Human RVECs were isolated from healthy donor eyes and primarily cultured and then identified by flow cytometry.The third to fifth generations of cells were used in this experiments.The fufang xueshuantong solution of 0.0625,0.1250,0.2500,0.5000 and 1.0000 g/L were added in the cuhure plate with 5 × 104/L cells respectively in the experimental groups,and t-BHP of 75,100,200 and 300 μ.mol/L were added in the model control groups.MTT was used to detect the A490and survival rate of RVECs.The apoptotic rate and death rate of the cells were evaluated by double staining of Annexin V-FITC/PI.Morphology of human RVECs were examined using invert microscopy and Hoechst33258 staining.The expressions of nitro tyrosine (a marker of oxidative damage of protein)and 8-OHdG(a marker of oxidative damage of DNA)in human RVECs were assessed by the immunofluorescence staining.Western blot was used to detect the expressions of nuclear factorkappa B(NF-KB),p53,bcl-2 and bax after 6,12,24 hours t-BHP action.This study was approved by the Ethic Committee of Zhongshan Ophthalmic Center.Results No significant difference was found in A490value among the normal control group,0.0625,0.1250,0.2500,0.5000 and 1.0000 g/L fufang xueshuantong groups(F =1.989,P＞0.05).The survival rates of the cells were lower in 75,100,200 and 300 μmol/L t-BHP groups compared with corresponding fufang xueshuantong groups(t =14.57,13.82,21.51,32.64,P＜ 0.01).The percentages of normal cells were evidently lower in 75,100,200 and 300 μmol/L t-BHP compared with corresponding fufang xueshuantong groups(t=14.908,5.495,17.165,26.330,P＜0.01).The numbers of deformation and death of the human RVECs increased as the elevated concentration of t-BHP,but those in fufang xueshuantong groups were less than the t-BHP groups under the invert microscopy.Compared with t-BHP groups,the expressions of nitro tyrosine,8-OHdG,NF-KB,p53 and bax were lower but the expression of bcl-2 was higher in human RVECs with the statistically significant differences(P＜0.05).Fufang xueshuantong at the concentration of 0.2500 g/L showed maximally protective effect on human RVECs.Conclusions Fufang xueshuantong protects human RVECs against the t-BHP-induced injury through downregulating the expression of NF-kB,p53,bax and up-regulating the express of the bcl-2 protein.

Near-infrared (NIR) was used as rapid analysis method to identify the sulfur fumigated Puerariae Lobatae Radix. NIR spectra of the cross-sectional and longitudinal selection of samples were acquired. Principal component analysis was conducted. The samples were randomly selected. The different pretreatment methods were compared. Discriminant models were established for every type of spectra to calculate the recognition rate. The orthogonal test and nonparametric test were used to test data normality. The result showed that absorbance values of different sections were different due to the different structure, and the raw spectra were analyzed by PCA method. The result founded that the cumulative contribution rate was arrived at 99.2% while the PC numbers were arrived at 3. The pretreatment method based on the MSC + 1D + Savitzky-Golay was the best to establish the model. For the 50 models constructed with cross-section and longitudinal spectra and total spectra, the recognition rate were (94.4 ± 0.66)%, (94.4 ± 0.66)%, (95.3 ± 0.65)%, respectively, and no difference was observed. The NIR method could be used to identify the sulfur fumigated Puerariae Lobatae Radix.

The combined application of statins that inhibit HMG-CoA reductase and fibrates that activate PPAR-α can produce a better lipid-lowering effect than the simple application, but with stronger adverse reactions at the same time. In the treatment of hyperlipidemia, the combined administration of TCMs and HMG-CoA reductase inhibitor in treating hyperlipidemia shows stable efficacy and less adverse reactions, and provides a new option for the combined application of drugs. In this article, the pharmacophore technology was used to search chemical components of TCMs, trace their source herbs, and determine the potential common TCMs that could activate PPAR-α. Because there is no hyperlipidemia-related medication reference in modern TCM classics, to ensure the high safety and efficacy of all selected TCMs, we selected TCMs that are proved to be combined with statins in the World Traditional/Natural Medicine Patent Database, analyzed corresponding drugs in pharmacophore results based on that, and finally obtained common TCMs that can be applied in PPAR-α and combined with statins. Specifically, the pharmacophore model was based on eight receptor-ligand complexes of PPAR-α. The Receptor-Ligand Pharmacophore Generation module in the DS program was used to build the model, optimize with the Screen Library module, and get the best sub-pharmacophore, which consisted of two hydrogen bond acceptor, three hydrophobic groups and 19 excluded volumes, with the identification effectiveness index value N of 2. 82 and the comprehensive evaluation index CAI value of 1. 84. The model was used to screen the TCMD database, hit 5,235 kinds of chemical components and 1 193 natural animals and plants, and finally determine 62 TCMs. Through patent retrieval, we found 38 TCMs; After comparing with the virtual screening results, we finally got seven TCMs.

Objective To observe the histological change of different waves in treating SD rats of the long-pulse 1064nm Nd:YAG laser and the 560～1200 nm intense pulse light,in order to provide the theory bases of non-ablative rejuvenation.Methods Two waves were used on experimental mice.The dermic thickness and the expression of collagen typesⅠand Ⅲwere detected by HE stain and immunohistochemical methods. Semiquantitative analysis was used to determine the mean of absorbance.Results Thedermal thicknesses and the mean of absorbance of collagen typesⅠandⅢin two different waves were higher than those in common control groups(P＜0.05).The effect of Nd:YAG laser groups were higher than IPL groups(P＜0.05).The expression of collagen typeⅠwas higher than that of collagen type Ⅲ(P＜0.001).Conclusion After Nd:YAG laser or IPL irradiation,the dermal thickness and collagen typesⅠandⅢof SD rats are increased.The effects of Nd:YAG laser are better than those of 560～1 200 nm IPL.The expression of collagen type Ⅲ is obviously more than that of collagen typeⅠin the early,whereas the expression of collagen typeⅠis obviously more than that of collagen type Ⅲin the later.It proves that the mechanism of dermal remodeling of non-ablative skin rejuvenation is mainly correlation with raising range and time of collagen typeⅠ.
