To clarify the active components in Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma, main components were gradually knocked out from the capsules, the effects of knockout capsules on uterine contraction, TNF-α secretion, murine splenocytes (SPL) and hysteromyoma cells proliferation were evaluated, respectively. The inhibition of capsules on uterine contraction was weakened by gradient knockout of paeoniflorin, paeonol, and amygdalin. The suppression of capsulte on TNF-α secretion was reduced by gradient knockout of gallic acid, cinnamaldehyde, pentagalloylglucose, and pachyman. The promotion of SPL cells proliferation was reversed by gradient knockout of gallic acid, paeoniflorin, cinnamaldehyde, quercetin, and pachyman. The depression of capsules on hysteromyoma cells proliferation was attenuated by gradient knockout of paeoniflorin, paeonol, pentagalloylglucose, and albiflorin. In conclusion, the compounds mentioned-above could be the key active basis of Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma.

Objective To explore the effect of suledexide on renal injury and podocalyxin expression of podocytes in STZ diabetic desoxycorticosterone acetate (DOCA)-hypertensive rats. Methods Wistar rats were subjected to subcutaneous injection of streptozotocin(STZ), followed by uninephrectomy and subcutaneous administration of DOCA. Diabetic and hypertensive rats were randomly allocated to treatment with sulodexide or a combination of sulodexide and telmisartan for 8 weeks. Blood pressure (BP), 24-hour urinary albumin were measured every 2 weeks. Blood and urinary samples were collected to detect biochemical indexes of plasma and urinary β-acetyl-β-D-glucosaminidase (NAG) at the end of the study. Immunohistochemistry (IHC), RT-PCR and Western blot were performed to examine the expression and distribution of podocalyxin. Results STZ +DOCA-treated rats progressively developed hypertension, albuminuria and hyperglycemia. Hyperlipidemia and hypoinsulinemia were found in diabetic and hypertensive rats compared with controls. Albuminuia was significantly reduced in sulodexide group at week 8 and sulodexide plus telmisartan group at week 6 and week 8. Blood pressure decreased in sulodexide plus telmisartan group. No significant effects on lipid and glucose metabolism were observed in all treated groups. Histopathological index increased in STZ+DOCA-treated rats, but was significantly lower in sulodexide group as well as sulodexide plus telmisartan group. The number of podocytes on glomerular cross-section of the four groups were comparable. Segmental loss and down-regulation of podocalyxin were detected in STZ+DOCA-treated rats, which were greatly attenuated by sulodexinde, meanwhile, combination treatment preserved more podocalyxin expression in glomeruli than sulodexide monotherapy. Conclusion Sulodexide effectively reduces albuminuria, prevents loss of podocyte podocalyxin and alleviates renal damage in STZ diabetic DOCA-hypertensive rats.

OBJECTIVE:To investigate the effect of KCa3.1 channel on the function of EPCs. METHODS: The gene expression of KCa3.1, vWF and CD31 on EPCs were detected by qRT-PCR. CCK-8 kit, cell adherent method and Matrigel were used to detect the changes of cell proliferation, adhesion and in vitro angiogenesis; cell immunofluorescence or fluorescence activated cell sorter(FACS) was used to detect the protein expression of KCa3.1, vWF, CD31, integrin β1, integrin β3 separately. RESULTS: Blocking the function of KCa3.1 or interfering with the expression of KCa3.1 can attenuated EPC function of proliferation, adhesion and angiogenesis, but it can promote the differentiation of EPCs. Overexpression or activation of KCa3.1 channel can enhance EPCs proliferation, adhesion and angiogenesis but decrease the level of differentiation. The expression of integrin β1 on EPCs was attenuated with blocking KCa3.1 channel, but the expression effect was reversible by the activator. CONCLUSION: The alteration of KCa3.1 channel function or expression affect the biological characteristics and differentiation of EPCs.

Objective To determine the frequency of polymorphism at exon 26 (C3435T) of muhidrug resistance 1 gene (MDR1) in epileptic patients in the southern Chinese and to study the association of this polymorphism with pharmacoresistance.Methods DNA samples were obtained from 134 patients,of whom 72 were resistant to antiepileptic drug treatment and 62 were responsive to the treatment. Genotypes of the C3435T polymorphism were determined by polymerase chain reaction (PCR) followed by restriction digestion and gel electrophoresis.Genotype and allele frequencies in the drug resistant group were compared to those in the response group by Chi-square analysis.Results Of all 134 patients,33 (24.6%) had CC genotype,72 (53.7%) had CT genotype,and 29 (21.6%) had TT genotype.The frequency of CC genotype was significantly higher in the pharmaeoresistance group (33.3%) than that in the responsive group (14.5%,P=0.012).The frequency of the C allele was also significantly higher in the pharmacoresistance group (57.6%) than that in the responsive group (44.4%,P=0.03).When patients were divided by types of seizure into three groups:generalized seizure group,partial seizure group,and undefined seizure group,the CC genotype and C allele were associated with pharmacoresistance in the partial seizure group.Conclusions In the southern Chinese,the CC genotype and C allele are associated with resistance to the antiepileptic treatment.This finding needs to be verified in studies with larger sample size.

Objective To study whether ferulic acid can promote healing on chronic ischemic wounds and its possible mechanisms.Methods 40 male New Zealand white rabbits were randomly divided into 4 groups:vaseline group,ischemic control group,5％ ferulic acid group and recombinant bovine basic fibroblast growth factor for external use (rb-bFGF) group.Gross wounds were carefully observed and HE staining was used to observe the wound healing and immumohistochemical staining to observe the expression of the VEGF and CD31.The RNA was extracted to detect the expression of VEGF and HIF-1a by real-time PCR.Results The general observation and the HE staining of each specimen 11 days after operation all indicated that the duration of wound healing of the 5 ％ ferulic acid group was similar to that of the rb-bFGF group and markedly shorter than the ischemic control group and the vaseline smear group.The result of the immunohistochemical staining indicated that the content of the VEGF and CD31 expression of the 5 ％ ferulic acid groups and the rb-bFGF group made lit tle difference,but there was markedly less VEGF and CD31 in ischemic control group and the vaseline smear group.The result of the PCR showed that expression level of VEGF and HIF-1α in the 5 ％ fer ulic acid group was similar to that in the rb bFGF group and the vaseline smear group,but was obviously more than that of the ischemic control group and the vaseline smear group (P ＜ 0.05).Conclusions Ferulic acid can promote angiogenesis by increasing VEGF and HIF-1α which are closely related to angiogenesis and then promote the healing of chronic wounds.

Objective To discuss the growth suppressing, apoptosing effect of new type tumor-supressor gene-p33ING1 in stomach cancer cell strain, and to explore new strategies and methods in tumor therapy. Methods The PCDNA3/p33ING1 nuclear expressing microsome was constructed, p33ING1 and wt-p53 were implanted to human stomach cancer cell both and to evaluate the effect of p33ING1 and p53 toward stomach cancer cell and synergism between them. Results The PCDNA3/p33ING1 nuclear expressing microsome was successfully constructed. The human stomach cancer cell strain SSCG-7901 under implantation of p33ING1 and wt-p53 showed a significant decrease in cell growth, the coupling time was delayed, DNA synthetic phase was shortened and G0/G1 phase prolonged. The cell collapse increased. Conclusions Despite of the tumor-inhibiting effect and biochemical activation of p33ING1, it also plays a role with p53 gene in controling growth of stomach cancer cell, inducing cell collapse and hampering cell proliferation cycle. P33ING1 and p53 are synergistic to each other.
