To establish an HPLC-MS/MS method for the analysis of quercetin, kaempferid and isorhamnetin in rats plasma and study its pharmamacokinetics after an intragastrical administration of Hippophae rhamnoides extracts. Five healthy male Sprague-Dawley (SD) rats were given single doses of H. rhamnoides extracts (quercetin 26.35 mg x kg(-1), kaempferid 4.040 mg x kg(-1), isorhamnetin 31.37 mg x kg(-1)), and then their orbital sinus blood samples were collected at different time points. The drug plasma concentration of the three flavonoids was determined by HPLC-MS/MS method. After that, the main pharmacokinetics parameters were calculated by using Kinetica 5. 0. 11 software. The methodological test showed that the linear concentration ranges of quercetin, kaempferid and isorhamnetin were 7.500-600.0 μg x L(-1) (R2 = 0.998 5), 1.000-80.00 μg x L(-1) (R2 = 0.998 5 ) and 10.00-800.0 μg x L(-1) (R2 = 0.998 0), respectively. The inner and inter-days precisions were both less than 14.0%. The plasma samples showed a good stability and consistency with the requirement of biological sample analysis after the samples were frozen once and placed at - 20 degrees C for 15 d and room temperature for 6 h and the treated analytes were placed at -20 degrees C for 24 h. For quercetin, the pharmacokinetic parameter t(½β), AUC(0-∞), MRT(0.∞), C.(max) and T(max) were (113.3 ± 19.37) min, (12 542.14 ± 3 504.05) μg x h x L(-1), (119.6 ± 13.29) h, (164.6 ± 27.33) μg x L(-1) and (5.199 ± 0.840 3) h, respectively. For kaempferid, the pharmacokinetic parameters t(½β), AUC(0-t), MRT(0-∞), C(max) and T(max) were (79.85 ± 17.15) min, (934.51 ± 94.59) μg x h x L(-1), (81.50 ± 13.75) h, (80.15 ± 14.24) μg x L(-1) and (3.827 ± 0.902 7) h, respectively. For isorhamnetin, the pharmacokinetic parameters t1,2,, AUC(0-t), MRT(0-∞), C(max) and T(max) were (118.3 ± 20.73) min, (26 067.77 ± 4 124.60) μg x h x L(-1), (129.0 ± 16.30) h, (269.6 ± 29.32) μg x L(-1) and (6.513 ± 1.450) h, respectively. The HPLC-MS/MS analysis method established in this study was proved to be sensitive and accurate and could be applied in the pharmacokinetic study of quercetin, kaempferid and isorhamnetin in rat plasma.

OBJECTIVETo investigate the impact of ethanol extracts from Sedum sarmentosum (ESB) on STAT-3 signaling and its probable molecular mechanism in inducing apoptosis.

METHODMTT assay was used to detect the impact of ESB on HepG2 cell proliferation. FITC-Annexin V-FITC /PI double-labeling were used to investigate the impact on hepatoma carcinoma cell apoptosis. Western blot analysis was used to test the expression levels of cell apoptosis-related proteins Caspase-3, Caspase-9, PARP, P-STAT-3 (Tyr705) , STAT-3, Bcl-2, Mcl-1.

RESULTESB could notably inhibit proliferation of HepG2 cells, and induce HepG2 cell apoptosis, with the dose-dependent inhibitory effect. In addition, ESB could inhibit STAT-3 signaling, down-regulate Mcl-1 and Bcl-2 expressions, and induce degradation/activation of apoptosis-related proteins Caspase-3 and Caspase-9 and PARP degradation in a dose-dependent manner.

CONCLUSIONESB inhibits HepG2 cell proliferation and induces apoptosis by inhibiting STAT-3 signaling and Mcl-1 and Bcl-2 expressions.

To explore the effect of Kudiezi injection on renal function in the real world, in order to provide the basis for the clinical medication safety. Patient aged between 18-80 were selected from 18 large hospitals information system (HIS) databases established by clinical research institute for basic traditional Chinese medicine of China academy of Chinese medical sciences. The patients who were treated with Kudiezi injection (24 225 cases) were defined as the exposed group, whereas those who were not treated with Kudiezi injection (14,191 cases) were defined as the non-exposed group. The propensity score method was used to balance the confounding factors. Classic logistic regression, GBM weighted propensity score logistic regression, GBM propensity score weighted logistic regression with covariate and sensitivity analysis were adopted to study the effect of Kudiezi injection on renal function. The results showed no significant difference in the possibility in abnormality in serum creatinine (Scr) (P = 0.940, 0.679, 0.834) and urea nitrogen (BUN) (P = 0, 0.045, 0.164) between both groups. Therefore, the existing data indicated no damage of Kudiezi injection on renal function. Because this study is a retrospective study based on the real world, there may be unknown confounding factors and potential bias. Therefore, further studies shall be conducted to monitor whether Kudiezi injection causes damage on renal function, in order to ensure the clinical medication safety.

Objective To explore the effect of fluoride and arsenic pollution on bone metabolism in exposed population. Methods One hundred and fifty-two fluoride and arsenic exposed people were selected from Jiaole village, Yuzhang town, Xingron county, Guizhou province in 2006, and 59 not exposed people from Daguoduo village 13 km away from Jiaole village were selected as control. Urinary fluorine(UF), urinary arsenic (UAs), urinary hydroxyproline (UHYP), cross-linked N-telopeptides of type I collagen (UNTX) and bone strength index(STI) were detected. Results The main effect of fluoride on UHYP and UNTX were statistically significant (F = 9.785, 4.225, P < 0.01 ), but was not significant on STI(F = 0.183, P > 0.05). The main effect of arsenic on UNTX was statistically significant (F = 2.660, P < 0.05 ), but was not significant on UHYP and STI(F = 2.012, 0.183,all P > 0.05). The interaction between fluoride and arsenic on UNTX was statistically significant (F= 2.429, P <0.01), but was not significant on UHYP and STI(F= 1.218, 1.001, all P> 0.05). Conclusions Fluoride exposure can affect the metabolism of collagen and bone resorption, and Arsenic exposure main affect bone resorption, fluoride and arsenic co-exposure have more significant effect on bone resorption. UNTX may be used as biological biomarker of bone metabolism for population co-exposed to fluoride and arsenic in health monitoring.

Dendritic cells (DCs)are the most potent antigen presenting cells,which play crucial roles in initiating and amplifying both the innate and adaptive immune responses.In DCs' whole life,the dynamics of cytoskeleton is involved in the regulation of their deformation,migration,adhesion,endocytosis and antigen presentation.The cytoskeleton is a complex system and regulated by lots of cytoskeletal proteins.With the research going,our understanding on cytoskeleton system is getting clear.Based on these,we summarized the effects of filamentous actin (F-actin)cytoskeleton remodeling on the morphology and immune functions of DCs.

italic>Alangium chinense is a commonly used medicinal plant of Alangiaceae Alangium, one of the characteristic Miao medicines in Guizhou. The genus is strongly differentiated and has complex morphological variation, with significant differences in active ingredients and potency among herbs. In this paper, we sequenced the chloroplast genomes of Alangium chinense subsp. Pauciflorum, Alangium chinense subsp. Strigosum and Alangium kurzii Craib using Illumina high-throughput sequencing technology. The genomes of Alangium chinense subsp. Pauciflorum, Alangium chinense subsp. Strigosum and Alangium kurzii Craib chloroplasts were sequenced, their assembly annotation and structural characterization were completed, and the genomes of the congeners Alangium chinense and Alangium alpinum were downloaded from NCBI for comparative analysis. Finally, the phylogenetic tree was constructed by selecting published species with close affinity to Alangium chinense family from NCBI. The results were as follows: Alangium chinense subsp. Pauciflorum, Alangium chinense subsp. Strigosum and Alangium kurzii Craib chloroplast genomes were 156 670, 156 672 and 156 871 bp in length, with a typical four-segment structure, all containing one long single copy region (LSC), one short single copy region (SSC) and two inverted repeat regions (IRa and IRb). All of them were annotated to 133 genes, including 88 protein-coding genes, 37 tRNA genes and 8 rRNA genes. Three types of long repeat sequences and SSR loci, forward repeats, palindrome repeats and reverse repeats, were found in all chloroplast genomes. Comparative genomic analysis showed that there was diversity in the boundary transition regions of the five species, no rearrangements or inversions were found in the chloroplast genome, and there were significant differences in the coding regions of ndhA, ycf1, rpl16, ycf2, and petD genes, which provided new loci for molecular identification of Patagonia. In the phylogenetic analysis, Alangium kurzii var. kurzii clustered as a single species, and Alangium chinense subsp. Pauciflorum and Alangium chinense subsp. Strigosum clustered as a single species, with a support rate of 93 and close affinity, indicating that the phylogenetic tree can be used for the species identification. This paper can provide a basis for the taxonomic identification of Alangium, ensure the safety of clinical use of anise herbs and regulate the market of Alangium chinense herbs.

OBJECTIVETo investigate the factors associated with postoperative fecal incontinence after anorectal procedures.

METHODSA total of 1074 patients underwent anorectal procedures in the Department of Colorectal Surgery at the Coloproctology Hospital of Shenyang. Factors associated with postoperative fecal incontinence were analyzed retrospectively.

RESULTSFollow-up was available in all the patients. One hundred and forty-four(13.4%) patients developed mild incontinence, and 57(5.3%) moderate incontinence. There was no complete incontinence. The overall incontinence rate was 18.7%. The incontinence rate was 41.8%(107/256) after fistula procedures, higher than that after hemorrhoid procedures(12.4%,73/591) and fissure procedures(9.2%,21/227), and the differences were statistically significant (P<0.01). Among 490 patients who received injection therapy for internal hemorrhoids, patients who received 10 ml of Xiaozhiling or more had a mild incontinence rate of 10.4%(27/259) and a moderate incontinence rate of 2.3%(6/259), and in those who received less than 10 ml of Xiaozhiling, the mild incontinence rate was 9.5%(22/231) and moderate incontinence rate was 4.3%(10/231). The differences were not statistically significant (all P>0.05). In 354 patients who underwent hemorrhoidectomy, the mild incontinence rate and moderate incontinence rate were both 14.1% in those who had excision of 3 or more hemorrhoids, and were 3.9%(11/283) and 2.1% (6/283) in those who had excision of less than 3 hemorrhoids, and the differences were statistically significant (P<0.01). There was no difference in Incontinence rate was not associate with fistula or fissure procedure (P>0.05).

CONCLUSIONSThe incidence of incontinence is high after fistula procedures. Excision of hemorrhoids should not exceed 3 hemorrhoids. Wider adoption of injection therapy is encouraged.
