Sini decoction (SND), a classical traditional Chinese medicine emergency formula recorded in Shanghan Lun (Treatise on Febrile Diseases), which is composed of Aconiti Lateralis Preparata Radix, Glycyrrhizae Preparata Radix and Zingiberis Rhizoma. Modern clinical and pharmacological researches have shown that SND can protect the myocardium effectively during myocardial ischemia reperfusion injury (MI-RI). A myocardial ischemia reperfusion injury model of H9c2 cardiomyocytes in vitro has been established. Four groups, control group, MI-RI Model group, SND group and SND without Glycyrrhizae Radix group, were arranged. The livability, the level of LDH and CK activity in H9c2 cardiomyocytes in different groups were tested. By combining with principal components analysis (PCA), partial least squares discriminant analysis (PLS-DA), orthogonal partial least squares projection of latent structures-discriminant analysis (OPLS-DA), 17 biomarkers in extracellular fluid were identified and 15 of them were related to the pathway of biological processes. The results showed that the attenuate and synergistic mechanism between Aconiti Lateralis Praeparata Radix and Glycyrrhizae Radix for toxicity reduction was related with the glycolysis, lipid metabolism, citrate cycle and nitrogen metabolism of amino acids metabolism. The study proved the effect on H9c2 cardiomyocyte treated by MI-RI injury both SND group and SND without Glycyrrhizae Radix group, and compared with the SND without Glycyrrhizae Radix, the protective effect of myocardial ischemia reperfusion injury model of H9c2 cardiomyocyte from SND was stronger.

To purify recombinant human nucleoside diphosphate kinase A (rhNDPK-A) efficiently in pilot scale, cells of rhNDPK-A producing E. coli were homogenized by high pressure under 4 degrees C, 950 Pa. The insoluble debris was removed by microfiltration and the soluble portion was concentrated by ultrafiltration. The resulted crude sample was loaded on DEAE-sepharose Fast Flow. The target fraction was collected and then load on Cibacron Blue 3GA Sepharose CL-4B. Eluted with buffer containing ATP from the AC column, rhNDPK-A was polished with ultrafiltration. The results showed that after homogenized 2 rounds, 1500g cells of E. coli brought crude sample containing 47.6g NDPK-A. Treated with microfiltration and ultrafiltration, 27.3g of NDPK-A were recovered from this bacteria homogenate. After 2-step purification with column chromatography and then polished with ultrafiltration, 17.2 g rhNDPK-A were collected with purity of 96.3%. The recovery of the whole purification process was 36.2%, and the productivity of rhNDPK-A was 1.15 g per 100 g wet cells. Comparing the recovery of each purification step, it was found that the recovery of polish is higher than that of affinity chromatography, which is higher than that of ion exchange chromatography. The limit step was the process of sample pretreatment among the 4 purification steps. Combine with the fermentation results reported before, it was deduced that the productivity of rhNDPK-A was 510 mg/L. In conclusion, an easily controlled purification condition with high yield provides material for the translation researches of NDPK; In addition, it was suggested the crucial step determine the recovery of non-secretive recombinant proteins might be the process of sample pretreatment, not be the process of column chromatography.

OBJECTIVEThis study was to explore the correlations between genetic variants in MMP2-1306C/T, TIMP2 2379C/T, TIMP2 303G/A and the genetic susceptibility to gastric carcinoma (GC) in Fujian province, China.

METHODSA case-control study was conducted. Polymorphisms of MMP2-1306C/T, TIMP2 2379C/T, TIMP2 303G/A in 479 gastric carcinoma patients and 469 cancer-free controls, frequency-matched by age and sex, were determined by Matrix-Assisted Laser Desorption/Ionization Time of Flight Mass Spectrometry (MALDI-TOF-MS). Multivariate logistic regression analysis was used to evaluate the correlations between the polymorphisms with the susceptibility to gastric cancer. Tests for an interaction between the MMP2-1306C/T and TIMP2 2379C/T or TIMP2 303G/A were performed using the likelihood ratio test.

RESULTSThe frequencies of GG, AG, AA of TIMP2 303G/A in gastric cancer group were 55.9% (267/478), 38.7% (185/478) and 5.4% (26/478); and those in control group were 53.1% (243/458), 36.9% (169/458) and 10.0% (46/458), which showed a significant difference between the patient and control groups (χ(2) = 7.0, P = 0.03). As compared with AA genotype, patients with GG + AG had a significantly higher risk of the cancer with OR of 1.94 (95%CI: 1.2 - 3.2). The frequencies of GG + AG and AA of TIMP2 303G/A in the muscle group were 87.5% (70/80), 12.5% (10/80), however, those in the serosa and beyond group were 96.0% (382/398), 4.0% (16/398), respectively, which showed a significant difference between the patient in muscle group and the serosa and beyond group (χ(2) = 9.32, P = 0.002). As compared with AA genotype, patients with GG + AG had a significantly higher risk in tumor invasion with OR of 3.4 (95%CI: 1.5 - 7.8). The frequencies of CC + CT, TT of TIMP2 2379C/T in the lymphoma node non-metastasis group were 93.4% (113/121), and 6.6% (8/121), but those in the lymphoma node metastasis group were 98.6% (349/354) and 1.4% (5/354), respectively, which showed a significant difference between the patient in the lymphoma node non-metastasis group and in the lymphoma node metastasis group in genotype distributions of TIMP2 2379C/T) χ(2) = 9.16, P = 0.002). As compared with TT genotype, patients with CC + CT had a significantly higher risk in lymph node metastasis with OR of 4.9 (95%CI: 1.6 - 15.3). MMP2-1306C/T genotype was not associated with tumor size, tissue differentiation, invasion, TNM nor lymph node metastasis of gastric carcinoma (χ(2)(tumor size) = 0.05, P = 0.98; χ(2)(depth of invasion) = 1.87, P = 0.39; χ(2)(histological type) = 0.55, P = 0.76; χ(2)(LN metastasis) = 0.44, P = 0.80; χ(2)(TNM) = 2.6, P = 0.28). There was no significant interaction between the polymorphisms of the two genes observed (χ(2) values were 0.98 and 0.80, P values were 0.81 and 0.85).

CONCLUSIONPolymorphism of TIMP2 is significantly related with occurrence and development of GC and maybe acts as a new biomarker of GC in prognosis.

Dioscin is a natural steroid saponin derived from several plants, showing potent anti-cancer effect against a variety of tumor cell lines. In the present study, we investigated the anti-cancer activity of dioscin against human LNCaP cells, and evaluated the possible mechanism involved in its antineoplastic action. It was found that dioscin (1, 2 and 4 μmol/L) could significantly inhibit the viability of LNCaP cells in a time- and concentration-dependent manner. Flow cytometry revealed that the apoptosis rate was increased after treatment of LNCaP cells with dioscin for 24 h, indicating that apoptosis was an important mechanism by which dioscin inhibited cancer. Western blotting was employed to detect the expression of caspase-3, Bcl-2 and Bax in LNCaP cells. The expression of cleaved caspase-3 was significantly increased, and meanwhile procaspase-3 was markedly decreased. The expression of anti-apoptotic protein Bcl-2 was down-regulated, whereas the pro-apoptotic protein Bax was up-regulated. Moreover, the Bcl-2/Bax ratio was drastically decreased. These results suggested that dioscin possessed potential anti-tumor activity in human LNCaP cells through the apoptosis pathway, which might be associated with caspase-3 and Bcl-2 protein family.

Novel uniform-sized magnetic molecularly imprinted polymers (MMIPs) were synthesized for selective recognition of active antitumor ingredients of kaempferol (KMF) and protoapigenone (PA) in Macrothelypteris torresiana (M. torresiana) by surface molecular imprinting technique in this study. Super paramagnetic core-shell nanoparticles (γ-MPS-SiO2@Fe3O4) were used as seeds, KMF as template molecule, acrylamide (AM) as functional monomer, and N, N'-methylene bisacrylamide (BisAM) as cross-linker. The prepared MMIPs were characterized by X-ray diffraction (XRD), Fourier transform infrared spectrum (FTIR), transmission electron microscopy (TEM) and thermo-gravimetric analysis (TGA), respectively. The recognition capacity of MMIPs was 2.436 times of non-imprinted polymers. The adsorption results based on kinetics and isotherm analysis were in accordance with the pseudo-second-order model (R (2)=0.9980) and the Langmuir adsorption model (R (2)=0.9944). The value of E (6.742 kJ/mol) calculated from the Dubinin-Radushkevich isotherm model suggested that the physical adsorption via hydrogen-bonding might be predominant. The Scatchard plot showed a single line (R (2)=0.9172) and demonstrated the homogeneous recognition sites on MMIPs for KMF. The magnetic solid phase extraction (MSPE) based on MMIPs as sorbent was established for fast and selective enrichment of KMF and its structural analogue PA from the crude extract of M. torresiana and then KMF and PA were detected by HPLC-UV. The established method showed good performance and satisfactory results for real sample analysis. It also showed the feasibility of MMIPs for selective recognition of active structural analogues from complex herbal extracts.
