Promotion of compound fujian tablet on the motor function rehabilitation and neurotization in rats with cerebral infarction / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the effects of Compound Fujian Tablet (FJT)on the neurotization in the cerebral infarction rats and to explore its mechanisms for promoting the motor skills.</p><p><b>METHODS</b>Totally 90 Wistar rats were randomly divided into the drug group, the model group, and the sham-operation group, 30 in each group. The rat model of middle cerebral artery occlusion (MCAO) was successfully established by electrocoagulation. Six hours after successful modeling, the rats of the drug group were orally administered with 9 g/kg FJT water solution, and the other groups were orally administered with equal volume of normal saline, once a day for two weeks. The motor skills of rats were examined by beam walking test. The expressions of nestin, polysialic acid neural cell adhesion molecule (PSA-NCAM), microtubule-associated protein 2 (MAP-2), growth-associated protein (GAP-43), and synaptophysin (Syn) in the brain tissue around the infarction were observed by in immunohistochemical assay. The mean staining gray or the optical density value were detected.</p><p><b>RESULTS</b>The 86 rats were recruited in the result analysis. After two weeks of administration, the neural function scoring was obviously higher in the drug group than in the model group with statistical difference (P < 0.01). The expressions of nestin, PSA-NCAM, MAP-2, GAP-43, and Syn in the brain tissue around the infarction were more obviously enhanced in the drug group than in the model group, showing statistical difference (P < 0.01).</p><p><b>CONCLUSION</b>FJT can promote neurotization and improve the motor skill recovery after cerebral infarction.</p>

Studies on the vascular endothelial cell injury model of blood stasis syndrome from the angle of combination of disease identification and syndrome differentiation / 中国中西医结合杂志

To study and analyze the model types, methods, and prospective of the vascular endothelial cell injury model of blood stasis syndrome from the angle of combination of disease identification and syndrome differentiation. We believe that studies on the vascular endothelial cell injury model of blood stasis syndrome should manifest the features of the combination of disease identification and syndrome differentiation. Following microscopic path and applying macroscopic theory could become an important technological platform for screening drugs of activating blood stasis and removing stasis, and providing beneficial clues for studies of Chinese medicine syndrome modeling.

Uncoupling protein 2 combats oxidative damage to human sperm / 中华男科学杂志

<p><b>OBJECTIVE</b>Germ cells are much more susceptible to oxidative stress than somatic cells. Accumulating evidence indicates that uncoupling protein 2 (UCP2) prevents the apoptosis of multiple types of cells induced by reactive oxygen species (ROS). The present study aimed to evaluate the protective effect of uncoupling protein 2 (UCP2) against oxidative damage to human sperm.</p><p><b>METHODS</b>Semen parameters were obtained from 97 semen samples by computer assisted sperm analysis (CASA), and the samples, based on the percentage of grade a + b sperm, allotted to Groups I (n = 25, grade a + b sperm > 50%), II (n = 24, grade a + b sperm 25%-50%), III (n = 24, grade a + b sperm 10-25%) and IV (n = 24, grade a + b sperm < 10%). The expressions of sperm UCP2 mRNA was detected by RT-PCR, and the malonaldehyde (MDA) content in ROS was determined in the sperm suspension.</p><p><b>RESULTS</b>The expressions of UCP2 mRNA in sperm were 1.51 +/- 0.24, 1.28 +/- 0.15, 1.17 +/- 0.20 and 0.69 +/- 0.18, and the MDA contents were (14.66 +/- 2.55), (16.00 +/- 2.09), (17.44 +/- 1.40) and (21.20 +/- 3.50) nmol/10(8) sperm in Groups I, II, III and lV, respectively. There was a significant negative correlation between the expression of UCP2 mRNA and the content of MDA (r = -0.633, P < 0.01), the former obviously reduced while the latter remarkably increased in the groups of lower sperm motility (P < 0.01).</p><p><b>CONCLUSION</b>UCP2 plays an important protective role against oxidative stress damage to human sperm by diminishing ROS production.</p>

Expression of uncoupling protein 2 on macrophages and its relation to interleukin-10/interferon ratio in patients with unexplained recurrent spontaneous abortion / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the relationship between the expression of uncoupling protein 2 (UCP2) and ratio of interleukin-10/interferon-gamma (IL10/IFNgamma) in the macrophages from patients with unexplained recurrent spontaneous abortion (URSA).</p><p><b>METHODS</b>Twelve women undergoing selective termination of normal early pregnancy (control) and 11 having URSA were included in this study. Magnetic cell sorting (MACS) was used to isolate the macrophages in the decidua, and the expression of UCP2 was detected with flow cytometry. Cytokine (IL10 and IFNgamma) secretion by the macrophages was detected by enzyme-linked immunosorbent spot-forming (ELISPOT) cell assay.</p><p><b>RESULTS</b>Compared to the control group, the women with URSA showed significantly decreased expression of UCP2 on decidual macrophage (136-/+25 vs 201-/+31, P<0.01), and the expression of UCP2 was positively correlated to the ratio of IL10/IFNgamma(r=0.73, P<0.01).</p><p><b>CONCLUSION</b>UCP2 may play an important role in the regulation of macrophage activity and cytokine secretion to contribute to spontaneous abortion.</p>

Studies on chromosome numbers of Salvia miltiorrhiza, S. flava and S. evansiana / 中国中药杂志

<p><b>OBJECTIVE</b>To study the numbers of chromosome in Chinese herb Salvia miltiorrhiza from 7 provinces in China, and S. flava as well as S. evansiana from Yunnan province in China.</p><p><b>METHOD</b>The young root was treated with the mixture of ice and water for 24 h, fixed with Carony's fixative for 6-12 h. After differentiating for 10-12 min with 1 mol x L(-1) hydrochloric acid at 60 'C and staining with carbol fuchsin,the section was observed under microscope.</p><p><b>RESULT</b>Chromosome numbers of S. miltiorrhiza and S.flava were 2n = 2x = 16. The numbers of S. evansiana were 2n = 4x = 32. The basic numbers of the chromosomes were x = 8. And tetraploids were observed in S. miltiorrhiza from Sichuan provices and Shandong provices.</p><p><b>CONCLUSION</b>The basic number of the chromosomes are x = 8. The chromosome numbers of S. miltiorrhiza, S.flava and S. evansiana are 16,16 and 32 respectively. As the chromosomes are the small or micro-small ones, it is difficult to use them for karyotype.</p>

Clinical study on effect of Xiaoyao Nose Drops in stopping episode of migraine / 中国结合医学杂志

<p><b>OBJECTIVE</b>To observe the effect of Xiaoyao Nose Drops (XYND) in stopping episode of migraine.</p><p><b>METHODS</b>Adopted was the randomized double-blinded placebo-controled method, with the 126 patients equally assigned to two groups, the treated group treated with XYND and the control group with placebo, and the therapeutic course was 30 days for all. The clinical total effective rate and effect in alleviating headache were observed. And hemorrheological parameters as well as the blood flow of the anterior cerebral artery (ACA), median cerebral artery (MCA) and posterior cerebral artery (PCA) were measured before and after treatment.</p><p><b>RESULTS</b>The clinical total effective rate and headache alleviating rate in the treated group were 93.33% and 96.67% respectively, while those in the control group were 18.33% and 20.00% respectively, and comparison between the two groups showed significant difference (all P < 0.01). The blood viscosity (high, middle and low shear), plasma viscosity and fibrinogen got lowered significantly in the treated group after treatment, showing significant difference in comparison either with those before treatment or with those in the control group after treatment (P < 0.05 or P < 0.01). The velocity of blood flow in all cerebral arteries lowered significantly, also showing significant difference in comparison either with those before treatment or with those in the control group after treatment (P < 0.05 or P < 0.01).</p><p><b>CONCLUSION</b>XYND is effective in stopping the headache of patients with migraine, and worth applying in clinical practice.</p>
