Hypertensive renal damage is based on the extent and duration of hypertension, renal damage caused by varying severity. Hypertensive renal damage due to various causes imbalance of vascular active substances, renal arteriosclerosis, so that the abnormal renal hemodynamic, renal ischemia, low specific gravity of urine, low osmotic pressure and urine. The rapidly increasing incidence of hypertensive renal damage has become one of the most important reasons of end stage renal disease (ESRD). Effective treatment of hypertension is limited by poor compliance and significant adverse reaction of antihypertensive drugs. Therefore, some patients have turned to Chinese medicine (CM), hoping that such treatments might improve the efficiency. The author reviews relevant theory and the latest researches, on the basis of combining diseases and syndrome, discusses state and achievement of hypertensive renal damage with Chinese herbal medicines from fundamental and clinical research and action mechanism from standpoints of Chinese herbal compound and herbal effective chemical composition to take future research for important reference.

Objective To further understand the cellular events of myocarditis,we have examined the myocardial mitochondria structure and activity of ATPase in mice with myocarditis,and observe the interventional effect of different doses of carptopril.Methods Sixty male Balb/c mice were randomly divided into 5 groups:infected coxsackie B3 virus(CVB3)group,infected CVB3 and treated with carptopril(in a dose of 10,30,or 100 mg/kg,twice a day)groups and control group.Captopril was administered after infection.The activity of Na+-K+-adenosine triphosphatase(Na+-K+-ATPase)and Ca2+-adenosine triphosphatase(Ca2+-ATPase)of myocardial mitochondrial as well as the morphological of myocardial mitochondrial were investigated on day 14.Results The activity of mitochondrial Na+-K+-ATPase and Ca2+-ATPase were significantly higher(Pa0.05).Conclusions The favorable effects of captopril exerts on myocyte mitochondria were shown in a dose-dependent manner.Thirty and 100 mg/kg,twice a day captopril protecs the membrane integrity and thus plays a role at the recovery of depressed mitochondrial Na+-K+-ATPase and Ca2+-ATPase activity and also in myocytes injury.

Objective To evaluate the feasibility of cell free fetal DNA(cffDNA)-based noninvasive prenatal diagnosis,we developed a precise technique for fetal sex determining region of Y chromosome(SRY)gene detection using size-fractionated cell-free DNA in maternal plasma.Methods Peripheral blood samples were collected form 117 pregnant women.cffDNA was extracted based on a column absorbent method and isolated by agarose gel electrophoresis.A dulex-polymerase chain reaction(PCR)was used to detected SRY gene and glycerol-dehyde-phosphate dehydrogenase(GAPDH)gene.Results Both SRY and GAPDH gene were detected in 86 cffDNA samples from women bearing male fetuses.And only GAPDH gene was detected in 71 cffDNA samples from women bearing female fetuses.These results had a coincidence whit those of villus or amniotic fluid samples.The specificity and sensitivity reached 100%(117/117)and 100%(66/66),respectively.Conclusion By agarose gel electrophoresis,re-extratedand and dulex PCR,size-fractionated cell-free fetal DNA in maternal plasma can be selective enriched and used to noninvasive prenatal diagnosis of sex-linked disorders and single gene disorders.

Objective To investigate the anti-tumor effect and mechanism of tamoxifen on rat C6 glioma cells. Methods C6 cells were cultured in Dulbecco's modified Eagle's medium (DMEM) with 3% fetal calf serum (FCS), and treated with tamoxifen of different concentrations, i.e. group A (1.25μmol/L), group B (2.50 μmol/L), group C (5.00 μmol/L), group D (10.00 μmol/L), group E (20.00 μmol/L) and control group (0.00 μmol/L). Morphological changes, MTT assay and 5-bromo-2'-deoxyuriding labeling ratio were assessed. Apoptosis was observed by flow cytometry. Results C6 cells treated with different doses of tamoxifen for 24, 48, and 72 hours became irregular in shape, while cells treated with vehicle grew normally. MTT assay showed that tamoxifen did not suppress C6 cell growth until 72 hours after treatment. Seventy-two hours after treatment, there were significant differences in cell viable rate between group A versus groups C, D and E; so did group B versus group D as well as group E (P<0.05). BrdU incorporation assay indicated significant difference of BrdU labbled index (BrdU LI) among groups A, C, E and control group 48 hours after treatment (P<0.05). And the BrdU LI decreased with the increased concentration of tamoxifen. Flow cytometry (FCM) showed significant difference between treated group and control group at 24, 48, and 72 hours after treatment (P<0.05). Conclusion Tamoxifen significantly suppresses the growth of C6 glioma cells in a time- and dose-dependent manner. The mechanism of tamoxifen suppressing C6 glioma cells may be inhibiting proliferation and inducing apoptosis. Therefore, tamoxifen can be a candidate as a chemotherapy agent for glioma.

Objective To explore the value of susceptibility-weighted imaging (SWI) for the assessment of chronic renal injury. Methods Thirty-nine patients with clinical diagnosis of chronic renal injury (RI group) who underwent routine renal MRI and SWI examination were retrospectively analyzed. They were divided into mild injured group (15 cases) and moderate to severe injured group (24 cases) by estimated glomerular filtration rate (eGFR). At the same time, 17 volunteers without chronic renal injury who had normal serum creatinine (Scr) and blood urea nitrogen were recruited as control group. All subjects underwent routine renal MRI and SWI examination. The ratios of cortex to medulla were measured and calculated in both kidneys' magnitude image and susceptibility weighted image, which were indicated as C/MMAG and C/MSWI. Independent sample t test was used to compare the differences of C/MMAG and C/MSWI between control group and RI group, and paired sample t test was used to compare the differences betweenC/MMAG and C/MSWI in each group. One-way ANOVA was used to compare the difference of C/MMAG and C/MSWI between the control group and the different RI groups. ROC was employed to assess the diagnostic efficacy of C/MMAG and C/MSWI in renal injury. Pearson linear correlation analysis was used to evaluate the correlation between C/MMAG, C/MSWI and eGFR, Scr in patients with renal injury. Results The C/MMAG and C/MSWI in the RI group were 1.101±0.039 and 1.071±0.046, respectively. C/MSWI was obviously lower than C/MMAG, and the difference was statistically significant (t=5.056, P<0.01). There was no significant difference between C/MMAG and C/MSWI in the control group (P>0.05). The C/MMAG and C/MSWI in the RI group were obviously lower than those in the control group, and the difference was statistically significant (t=4.564, 6.122;P<0.01).The C/MMAG and C/MSWI in the mild injured group and the moderate to severe injured group were significantly lower than those in the control group, the difference was statistically significant (P<0.05). While the differences of those between mild injured group and moderate to severe injured group showed no statistical significance (P>0.05). The area under ROC of C/MMAG and C/MSWI in diagnosis of renal injury were 0.853 and 0.952, respectively. C/MMAG was positively correlated with eGFR (r=0.460,P<0.01). Conclusions Susceptibility-weighted imaging can be used to assess chronic renal injury. Although it cannot reflect the degree of renal function damage, it has some value in the early diagnosis of mild renal injury.
