Aim The protective effect of total salvianolic acids (Sal) on cerebral hypoxia inmice was studied. Methods Acute cerebral hypoxia was induced by sodium nitrite scand decapitation.The effect of Sal on acute cerebral hypoxia in mice and neuronalhypoxia injury induced by sodium dithionite in primary cultures were ob-served. Results Sal in the doses of 10, 20 mg?kg-1 iv protected mice against theacute cerebral hypoxia and inhibited the production of lipid peroxidation in brain tis-sue of mice caused by cerebral hypoxia. Sal in the doses of 1~10 ?g? L-1 reduced therate of cell death and the content of MDA and lowered LDH content in extra-cellularbathing media in oxygen deprived cortical cultures.Conclusions Sal protects miceagainst cerebral hypoxia by suppressing the generation of lipid peroxide.

Though parched Chinese herbal medicines contain less effective or index components, their pharmacological actions do not reduce or even become improved to some extent. However, the current studies related to material basis could not explain the changes in property, flavour and efficacy of parched Chinese herbal medicines. Meanwhile, due to the lack of objective and specific evaluation indexes, the quality evaluation could not reflect features of parched Chinese herbal pieces. Therefore, how to break the bottleneck for the studies on parched Chinese herbal pieces, make further innovation and conduct in-depth studies on the material basis of parched Chinese herbal medicines are common problems that medical scholars are facing. According to the findings in the previous studies, the author proposed to explain the material basis of parched Chinese herbal medicines by studying Maillard reaction and establish specific quality evaluation indexes according to the features of parched Chinese herbal pieces, and conducted relevant studies.

Objective To explore the relationship between DNA repair gene XRCC1 and XPD polymorphisms and individual susceptibility to prostate cancer. Methods PCR-restriction fragment length polymorphism assay was used to analyze the XRCC1 (C26304T and G28152A) and XPD A35931C polymorphisms in 358 prostate cancer patients and 312 healthy controls. Unconditional logistic regression analysis was performed to calculate odd ratio (OR) and 95% confidence interval (CD for estimating the correlation between different genotypes and prostate cancer risks. Results Forty-seven(13.1%) cases present XRCC1 28152AA genotype in prostate cancer group, while 24 cases in the control group (7. 1%), individuals with this genotype had a significantly increased risk for prostate cancer (OR 1. 924, 95%CI=1.126 - 3. 288, P=0. 017). There was no significant difference between two groups at XRCC1 C26304T and XPD A35931C sites. Combined analysis of the three sites polymorphisms showed that individuals with XRCC1 28152 AA and XPD 35931AC+CC genotype had a higher risk of prostate cancer than those with three wild genotypes (OR = 3. 087,95%CI 1. 081 - 8.813;OR = 3. 376,95%CI 1.067-10.683;OR 3. 216,95%CI=1. 439-7.188,P = 0. 004). Analysis stratified by age of onset, PSA, Gleason score and T stage revealed that XRCC1 28152AA and XPD 35931 AC+CC high-risk genotype was especially associated with early age at onset of prostate cancer (P<0. 05). Conclusions The XRCC1 and XPD genotypes may be contributed to the risk of developing prostate cancer, particularly for younger patients.

BACKGROUND:Simvastatin enhanced the expression of bone morphogenetic protein-2(BMP-2),which plays an anabolic role in bone metabolism and osteoblastic lineage differentiation.However,little is known about the molecular mechanism of simvastatin on regulation of bone marrow stromal cells differentiation.OBJECTIVE:To investigated the effect of simvastatin on osteoblastic differentiation of bone marrow stromal cells based on genetics level.METHODS:Bone marrow stromal cells derived from femur and tibia were cultured in different mediums with simvastatin or Vehicle for 7 days Following extraction and purification,mRNA was reverse-transcripted into cDNA.Fluorescence labelina was employed and the samples were then hybridized with oligonucleotide chip to screen the different genes,which were utillzed to analyze osteogenesis-related factors.Alkaline phosphatase and Von Kossa staining were performed at days 14 and 21,respectively.RESULTS AND CONCLUSIONS:At day 14,alkaline phosphatase-positive cells were more in the experimental group than control group.Von Kossa staining demonstrated that simvastatin could promote BMSCs osteoblastic differentiation and mineralization.Comparative analysis showed that 103 genes out of 22 575 rat genes had differential expression (≥2 fold or≤ 0.5 fold),and some genes were related to cell proliferation and ostoeblastic differentiation,including C/EBP δ,Cited,Ascl2,Ptpnl6,Wisp2,Tieg,etc.Simvastatin could induce osteoblastic differentiation of bone marrow stromal cells,involving in many osteogenetic-related genes.

To investigate the epidemic and evolutionary trends of enterovirus (EV) in the external environment of Yunnan Province, China, molecular typing was performed on 4 EV strains that were isolated from environmental sewage in Yunnan. The VP1 region of isolates was amplified by RT-PCR using universal enterovirus primers, and the amplified VP1 region was sequenced for GenBank BLAST search and genotype analysis. The 4 EV strains were identified as ECHO7. Their nucleotide and amino acid homologies with the VP1 sequences of 68 ECHO7 strains retrieved from GenBank were measured by Mega software analysis. Our findings showed that ECHO7 strains from environmental sewage and population samples were in different evolutionary branches. These strains showed typical geographical and temporal differences; In addition, there were different transmission chains at the same time and in the same area. ECHO7 strains isolated from sewage water and patients with acute flaccid paralysis during the same period in Yunnan belonged to different clusters and evolved at different speeds. Special concerns are needed for this problem. Continuous molecular biological surveillance of human EV in the external environment of Yunnan will provide strong support for early warning of EV diseases.

OBJECTIVETo observe the clinical effect of Huikangling Tablet (HT, extracted from Scabrous Patrinia root) on peripheral blood micrometastasis of differentiated thyroid carcinoma (DTC) patients.

METHODSTotally 87 DTC patients with positive micrometastasis were randomly assigned to the treatment group (45 cases) and the control group (42 cases). DTC endocrine inhibition treatment standards were executed in all patients. They all took levothyroxine sodium (50 microg/tablet, from low dose, 25 microg each time, once per day, 0.5 h before breakfast), and its dosage was gradually added one week later. The dosage was adjusted according to tested results of TSH combined recurrence risk stratification and endocrine suppression induced adverse reactions risk stratification. Patients in the treatment group took HT (0.4 g per tablet, 3 tablets each time, three times per day for a total of 12 weeks) combined TSH suppression therapy, while those in the control group only received TSH suppression therapy. Peripheral micrometastatic cytokeratin 19 (CK19) and polymorphic epithelial mucin1 (MUC1) were detected by FCM at week 4 and 12. Meanwhile, distant metastasis and adverse reactions were observed.

RESULTSAfter 4-week treatment positive micrometastasis was shown in 18 cases (40%) of the treatment group and 29 cases (69%) in the control group with statistical difference (chi2 = 5.68, P < 0.05). After 12-week treatment positive micrometastasis was shown in 7 cases (15.6%) of the treatment group and 17 cases (44.7%) in the control group with statistical difference (chi2 = 8.49, P < 0.01). Pulmonary metastasis occurred in 2 cases and bone metastasis in 1 case of the control group at follow-ups. Cervical lymph node metastasis without accompanied recurrence of thyroid cancer occurred in one case of the treatment group. No obvious liver or renal abnormalities occurred.

CONCLUSIONHT inhibited peripheral blood micrometastasis of DTC patients and its mechanism needed to be further studied.
