The high performance liquid chromatography-fluorescence micelle assay (HPLC-FMA) method for the content determination of polysorbate 80 in monoclonal antibody drugs was validated to study its applicability and transferability between various laboratories, and the feasibility to be included in the Chinese Pharmacopoeia. Both J.T. Baker and Nanjing Well-sourced polysorbate 80 was used in the collaborative validation of polysorbate 80 content analysis in seven different laboratories. The results show that when the protein concentration was no more than 20 mg·mL^-1 and the concentration of polysorbate 80 ranged from 0.05 to 0.5 mg·mL^-1, the method had good specificity. The recovery rates of the spiked samples ranged from 92.20% to 117.70% for J.T.Baker and from 93.90% to 117.20% for Nanjing Well. The intra-laboratory precision (%RSD) was less than 4.30% for J.T. Baker, and less than 2.60% for Nanjing Well, while the overall precision was less than 5.45% for J.T. Baker, and less than 6.70% for Nanjing Well. The linear correlation coefficient was more than 0.98 for J.T. Baker and more than 0.99 for Nanjing Well. The results of the collaborative validation prove that the HPLC-FMA method has good accuracy, precision, linearity, and specificity, and could be used for release control analysis of polysorbate 80 content in monoclonal antibodies across different laboratories.

Aim To establish a simple, rapid and accurate electroanalytical method for water soluble porphyrin meso-tetrakis-(4-sulfonatophenyl) porphyrin (TPPS4);to clarify the reaction between water soluble porphyrins and bovine serum albumin (BSA);and to determine the interaction of TPPS4 with BSA in the absence of presence of cyclodextrins (CDs) , separately. Methods Three methods including LSV,UV spectroscopy and fluorescence spectroscopy bad been employed to the relevant experiments. The way of employing three methods at the same time could make the experiment results more reliable. Results In the supporting electrolyte of NaH2 PO4-Na2 HPO4 ( pH 7. 18 ), a sensitive reduction peak of TPPS4 was found by linear sweep voltammetry (LSV), the peak potential (Ep) was-0. 70 V (vs SCE). The relationship between the second derivative peak of LSV (ip") and the concentration of TPPS4 was linear from 1.0 × 10-7mol·L-1 to 1.0 × 10-5mol· L-1,the square of correlation coefficients (r2) were 0. 998 3 and 0. 999 3, respectively. The relative standard deviation (RSD) was 0. 56% ( n = 5 ). The mean recovery of TPPS4 was 99.59％. In NH4C1-NH3· H2O buffers (pH 9.05), it was proved that BSA and TPPS4 could interact with each other and form 1:1 TPPS4-BSA supramolecular system. Moreover, the interaction between TPPS4 and BSA had been investigated by adding cyclodextrins (CDs). The interaction of TPPS4 with BSA was facilitated both by hydroxypropyl-β-CD (HP-3-CD) and sulforbutylether-β-CD (SBE-3-CD). Conclusion An electroanalytical method for TPPS4 has been established by LSV. The porphyrin drugs included by CDs could react with protein existing inside the human body easier. The consequences of this article also show that CDs will play important role in controlling and releasing the porphyrin drugs.

Objective To study the changes of P-selectin and E-selectin in pediatric patients with critical illness ,and analyze their relationship with the severity and prognosis of diseases.Methods Forprospective study,42 critically ill patients admitted in pediatric intensive care unit (PICU ) from September,2012 to March,2013 as critically ill group were enrolled,and blood specimens were collected with 24 hours after admission.Another 42 cases blood samples were collected from children's physical examination as control group.The severity of the critically ill patients were evaluated by Pediatric Critical illness Score (PICS)and Pediatric risk of score mortality (PRISM)-III.The levels of serum P-selectin and serum E-selectin were measured by double antibody sandwich enzyme-linked immunoassay (ABC-ELISA). Results P-selectin and E-selectin in control group children and critically ill patients group were (37.23 ± 8.99)ng/mL,(36.24 ±17.82)ng/mL,and (107.24 ±35.53)ng/mL,(114.93 ±40.17)ng/mL, respectively.There were statistical differences between two groups (P=0.000).The levels of P-selectin and E-selectin in acute phase were higher than that of levels in recovery phase in critically ill group (P =0.000).Negative correlation was observed between P-selectin concentration and the PCIS score (r =-0.673,P=0.000),as well as E-selectin (r=-0.548,P=0.000).P-selectin level and E-selectin level based upon PRISMⅢ≥10 group were significantly higher than they in PRISMⅢ <10 group (P=0.003,P=0.014).In critically ill children,the differences in P-selectin,E-selectin were significant higher in death patients (P=0.003;P =0.000).Compared with the non-sepsis illness group,the level of P-selectin and E-selectin in the severe sepsis patients were significantly higher (P =0.04,P =0.025 ). Conclusions The levels of P-selectin and E-selectin are closely related to the severity and prognosis in critically ill children.Measuring the level of P-selectin and E-selectin could be used as a judegment the severity and to understand pathological physiological process.

AIM:To investigate the effect of nuclear factor E2-related factor 2 (Nrf2) activation by 18α-gly-cyrrhetinic acid (18α-GA) on the proliferation and self-renewal of adult neural stem cells (aNSCs), and to explore an ef-fective way of maintaining the viability of aNSCs .METHODS:NSCs were dissociated from subventricular zone of the mice at postnatal days 0, 60, and 300.The expression levels of Nrf2 in the NSCs at various ages were compared .After treatment with 18α-GA, the expression of Nrf2 was examined by real-time PCR and Western blot.shRNA lentiviral vector (LV) car-rying green fluorescent protein (GFP) gene was constructed to knock down Nrf2 expression.The knockdown efficiency in the aNSCs was detected by real-time PCR and Western blot .Subsequently , the aNSCs were divided into DMSO group , 18α-GA group, LV-GFP group and LV-Nrf2-shRNA group.BrdU incorporation assay , Tuj1 staining, CCK-8 assay, Hoechst 33342/PI staining and detection of reactive oxygen species ( ROS) were performed to analyze the proliferation , dif-ferentiation, viability, apoptosis and oxidative stress levels of the NSCs .RESULTS:The mRNA expression level of Nrf2 in adult and aged NSCs was significantly lower than that in newborn NSCs (P<0.01), while the ROS level of aNSCs was significantly higher (P<0.05).After treatment with 18α-GA, the expression level of Nrf2 in the aNSCs was significantly up-regulated as compared with DMSO group ( P<0.01).Increased number of BrdU +and Tuj1 +cells was observed in 18α-GA group, indicating that 18α-GA-treated cells had higher viability (P<0.05).Meanwhile, there were fewer apop-totic cells and lower ROS level in 18α-GA group than those in DMSO group (P<0.05).After knockdown of Nrf2 in aNSCs and then treated with 18α-GA, there were less BrdU +and Tuj1 +cells, as well as the aNSCs with lower viability in LV-Nrf2-shRNA group (P<0.05).Moreover, the ROS level was increased in LV-Nrf2-shRNA group as compared with LV-GFP group (P<0.05).CONCLUSION:Activation of Nrf2 by 18α-GA elevates the antioxidant capacity of aNSCs , thus ameliorating the cell proliferation and differentiation potentials .

In this article, the research of chemical constituents and bioactivities in recent ten years has been reviewed of plants from the 12 genera in Flacourtiaceae related to the medicinal resources in China. The research in China about the plants from Flacourtiaceae was done very little, but many literatures have been reported abroad. The plants from Flacourtiaceae mostly contain the constituents such as aromatic glucosides, lignanoid glucosides, diterpenoids and cyclopentenoid cyanohydrin glucosides et al. These compounds or plant extracts mainly show antibacterial, antiviral, antitumor, hypolipidemic and hypoglycemic activities. The research of plants from Carrierea, Itoa and Bennettiodendron of Flacourtiaceae in China is still blank. The systemic research about chemical constituents and bioactivities of plants from these genera will play important roles in the discovery of novel natural products and active constituents, and provide valuable reference for the classifying of plants from these genera.

OBJECTIVETo observe the therapeutic effect of Xiaozheng Rongmu Powder (XRP) for the treatment of progressive CCl4-induced liver cirrhosis in rats.

METHODSRat liver cirrhosis model was established by subcutaneous injection of 50% CCl4-olive oil 2 mL/kg twice a week for 12 weeks. Experimental rats were divided into the control group treated by saline and the two treatment groups, treated with XRP and Xiaochaihu Decoction, respectively, with the treatment starting from the 9th week of modeling. Rats were sacrificed at the terminal of experiment, the death rate, character of ascites, liver histological changes, liver function, mRNA expression of hepatocyte mitosis and the liver fibrosis associated markers in rats were observed.

RESULTSAt the end of the 8th week of modeling, serum levels of ALT, AST and TBil were increased, and Alb decreased significantly in rats (P < 0.01), cirrhosis formation with ascites could be seen in all rats. Meantime, levels of vascular smooth muscle alpha-actin, transforming growth factor-beta1, collagen I A2, tumor necrosis factor-alpha, tissue inhibitor of melalloproteinase-1 mRNA increased, while matrix melalloproteinase-13 mRNA were decreased significantly (P < 0.01), with visible liver proliferation to some extents. Further changes of above-mentioned abnormalities and clear suppression of hepatocytes mitosis were found in the modeled rats at the end of the 12th week. As compared to those occurred in the control group, changes in the XRP treated group were significantly milder at the corresponding duration, and clearly active hepatocytes mitosis was shown.

CONCLUSIONXRP, a Chinese drug with the effect of dissolving phlegm, removing stasis and supplementing qi, could reverse the progress of cirrhosis formation induced by CCl4, and it brings potential new hope for the treatment of advanced cirrhosis by Chinese medicine.

AIM: To determine whether hydroxyapatite modified titanium promotes superior adhension and proliferation of rabbit corneal fibroblast in comparison with pure titanium.METHODS: We used bioactive hydroxyapatite to modify titanium surfaces. Fourth passage fibroblasts of rabbit cornea were seeded on hydroxyapatite modified titanium surfaces, pure titanium and glass surfaces. Cell adhension, proliferation and morphology were detected at 24 hours, 48 hours, and 72hours using a acridine orange stain. Further studies of cell morphology were performed using scanning electron microscopy.RESULT: Ceil counts were significantly greater on hydroxyapatite modified titanium surfaces at each time point(P＜0.05).At 24 hours, cell spreading was greater on hydroxyapatite-coated titanium and glass than on the pure titanium. At 72 hours, compared with pure titanium and glass surfaces, the cells on hydroxyapatite modified titanium surfaces had greater spreading area and longer stress fibers.CONCLUSIONS: Hydroxyapatite modified titanium promotes superior adhension and proliferation of rabbit corneal fibroblast in comparison with pure titanium.
