RESUMO

Central retinal artery occlusion(CRAO), also known as eye stroke, always results in acute and painless visual loss. At present, conservative treatments, such as eye massage, lowering intraocular pressure and vasodilators have little effect on reducing visual loss. Intra-arterial thrombolysis(IAT)has significantly improved prognosis in patients with acute ischemic stroke, thus IAT has been gradually applied in the treatment of CRAO. IAT injects fibrinolytic drugs directly into the ophthalmic artery by a microcatheter, and dissolves the emboli that block the central retinal artery to restore the blood flow of the retina. Theoretically, IAT may be effective for CRAO as what has been found for stroke, but existing clinical studies exhibited inconsistent results. This paper summarizes the feasibility, efficacy, and safety of IAT treatment in CRAO. It will also analyze related factors that affect the prognosis, putting forward potential development directions and providing insights for the further clinical application of IAT.

RESUMO

Intestinal flora imbalance and abnormal glucose and lipid metabolism are important risk factors and pathological mechanisms of colorectal polyps. "Spleen deficiency and dampness accumulation" is the core pathogenesis of colorectal polyps. The imbalance of intestinal flora is related to spleen deficiency, and the application of Chinese herbs for invigorating spleen is helpful to the recovery of intestinal flora balance. Abnormal glucose and lipid metabolism is related to dampness accumulation, and it is effective to treat it with bitter and spicy herbs or spleen-invigorating and dampness-eliminating herbs. The interaction between intestinal flora imbalance and abnormal glucose and lipid metabolism changes intestinal microenvironment, damages intestinal epithelial cells, causes abnormal proliferation of intestinal stem cells and leads to colorectal polyps, which is consistent with the pathogenesis of spleen deficiency and dampness accumulation in Traditional Chinese Medicine. Thus, we tried to explore the biological connotation of the pathogenesis of "spleen deficiency and dampness accumulation" of colorectal polyps from the perspective of the interaction of intestinal flora and glucose and lipid metabolism, in order to provide reference for identifying high-risk population and analyzing the therapeutic mechanism of compound prescription for invigorating spleen and removing dampness.

RESUMO

BACKGROUND: Diverse groups, including college students, are being encouraged to practice yoga. Research suggests that college students fail to attain the mental and physical benefits of yoga practice. OBJETIVE: The purpose of this study was to utilize the fourth-generation, multi-theory model (MTM) of health behavior change to explain change regarding yoga practice of asanas, shava asana, pranayama, dhyana, yama and niyama among college students. METHOD: This cross-sectional study relied on a quota sample of students 18 years and older attending Jackson State University, a historically black college in Jackson, Mississippi, United States. MEASURES: A 36-item face and content valid instrument was used to collect data. Stepwise multiple regression was used to analyze the survey data for identifying the best possible predictors of yoga practice. A statistical significance level of 0.05 was set a priori. RESULTS: A total of 70 participants, mean age 28.62 years (SD, 6.11), predominately female (84%) and black (87%) completed the survey. The initiation model constructs- changes in the physical environment (ß = 3.99, P = .002) and behavioral confidence (ß = 0.331, P = .008)-were significant, explaining 40% of the variability in the dependent variable. Practice change was statistically significant (F1,65 =7.569; P = .0001; adjusted R2 = 0.460) for the maintenance model, explaining 46% of the variability. CONCLUSION: The MTM model of health behavior change is effective for explaining the intent to initiate and maintain yoga behavior among college students.

RESUMO

In the clinical practice of rheumatic immune diseases in traditional Chinese medicine (TCM),it`s still unclear about the dominant diseases and breakthrough points. It`s urgent missions to formulate TCM diagnosis and treatment guidelines widely recognized and integrated by traditional Chinese medicine and Western medicine. In order to clarify the dominant diseases and breakthrough points in rheumatism,China association of Chinese medicine initiated a research group covering experts in the field of rheumatism of traditional Chinese medicine and Western medicine. Based on questionnaire survey and on-site discussion,experts had reached the following consensus. Evidence-based medicine research using modern medical methods and scientific methods should be carried out to provide objective clinical evidences. "Four mutuality" were put forward as the basis for the work of integrated traditional Chinese and Western medicine,that is the mutual communication using the exchangeable context,the mutual explanation using common theories,the mutual certification using common standards,and the mutual integration using common means. Key works should focus on solving refractory rheumatism in the future. In terms of dominant diseases and breakthrough points,this paper introduces 21 breakthrough points in 6 dominant diseases,including rheumatoid arthritis,ankylosing spondylitis,Sjogren's syndrome,hyperuricemia and gout,systemic lupus erythematosus and fibromyalgia syndrome. Advice on this discussion can provide valuable references for developing the treatment scheme of rheumatism with TCM and integrated Chinese and Western medicine and clinical practice and scientific research.

RESUMO

OBJECTIVE@#Herbal medicine is an important therapeutic option for benign prostatic hyperplasia (BPH), a common disease in older men that can seriously affect their quality of life. Currently, it is crucial to develop agents with strong efficacy and few side effects. Herein we investigated the effects of the extract of Rauwolfia vomitoria, a shrub grown in West Africa, on BPH.@*METHODS@#Rats with testosterone-induced BPH were treated with R. vomitoria. Prostates were histologically analyzed by Hematoxylin and eosin staining. Proliferation index and the expression levels of androgen receptor and its associated proteins were quantified through immunohistochemistry and immunoblotting. Androgen receptor target genes were examined by quantitative real-time polymerase chain reaction. The sperm count and body weight of rats were also measured.@*RESULTS@#The oral administration of R. vomitoria extract significantly reduced the prostate weight and prostate weight index in BPH rats, supported by the decreased thickness of the prostate epithelial layer and increased lumen size. Similar effects were observed in the BPH rats treated with the reference drug, finasteride. R. vomitoria extract significantly reduced the testosterone-induced proliferation markers, including proliferating cell nuclear antigen and cyclin D1, in the prostate glands of BPH rats; it also reduced levels of androgen receptor, its associated protein steroid 5α-reductase 1 and its downstream target genes (FK506-binding protein 5 and matrix metalloproteinase 2). Notably, compared with the finasteride group, R. vomitoria extract did not significantly reduce sperm count.@*CONCLUSION@#R. vomitoria suppresses testosterone-induced BPH development. Due to its milder side effects, R. vomitoria could be a promising therapeutic agent for BPH.

RESUMO

Tea is one of the most popular beverages worldwide. Its categories have a great relationship to its beneficial medicinal properties. The present work attempted to study the feasibility to use multispectral imaging technique as a rapid and non-destructive method to discriminate tea varieties. Two categories of tea discriminated hardly by naked eye were sorted. The images were 1 036 pixels vertically by 1 384 pixels horizontally with 24-bit depth, and were captured using a red (R) waveband, near infrared (NIR) waveband and green (G) waveband multispectral digital imager, MS3100 (Duncan Technologies, Inc., CA, USA). The three wavebands of image (Red, Green, NIR) can be composed into one image which contains more information than images recorded by ordinary digital cameras, especially, the NIR image is more sensitive to the color of organic matter than visible spectrum. The three images of one sample can be obtained simultaneously. The color features of tea were calculated using the standard notations: mean and mean square deviation. Then, the two color features of 3CCD and ordinary digital cameras were extracted and calculated by Matlab 7. 3 software respectively, and were contrasted. A total of 60 samples were adopted, and the features of mean and mean square deviation of NIR waveband image were applied as inputs to a back propagation neural network (BP-ANN) with one hidden layer. The forty samples (twenty for each category) were selected randomly to build BP-ANN model, and this model was used to predict the varieties of 20 unknown samples (ten for each category). The two categories of tea can be discriminated by the information of color of images of 3CCD, but can not by the ordinary digital cameras. The result indicted that the discrimination rate of classification set of BP-ANN model was up to 100% within 0.3 of threshold. It concluded that multi-spectral imaging technique has a high potential to identify categories of green tea fast and non-destructively.

RESUMO

OBJECTIVE@#To screen the differentially expressed gene profile from the smooth muscles in the fundus uterus at the active stage of labor, and to provide candidate genes for picking out the drug targets related to uterine contraction.@*METHODS@#Differentially expressed genes of uterine smooth muscles in the corpus from pro and post spontaneous parturition and those induced by oxytocin,as well as those from the corpus and the lower portion spontaneous parturition,were scanned respectively by human full-length genetic cDNA microarray with 8064 probe sets. Semi-quantitative RT-PCR was applied to testify the expression of voltage dependent calcium channel-L subtype (CACNA). The differentially expressed genes in the structure and function of the drug targets were picked out by bio-informatics to serve as candidate drug targets related to uterine contraction.@*RESULTS@#The expressions of 29 genes were upregulated in fundus smooth muscles from the pro and post natural parturition, the pro and post inductive parturition of oxytocin, and the natural parturition. The expression of CACNA gene in RT-PCR was in accordance with that in the microarray. Among the 29 genes, neuromedin B receptor (NMBR) gene and neuropeptide Y (NPY) gene were the genes which not only had the targets of uterine contracted medicine, but also could contract the uterine. The differential expression ratios of NMBR in the above 3 types of uterine myometrium were 6.9,11.3, and 9.0, respectively while those of NPY were 6.0,29.8, and 2.9 respectively.@*CONCLUSION@#NMBR, whose expression in the uterine smooth muscles is always up-regulated at different parturition conditions, is likely to be an ideal candidate target of uterotonic drugs.

<p><b>OBJECTIVE</b>To observe the clinical efficacy of Xiaoshui Decoction (XSD) in treating ascites in patients suffered from primary liver cancer of Pi-deficiency with damp harassment syndrome (PDDHS) as well as to study the effect through the experiment in mice.</p><p><b>METHODS</b>Sixty-one patients confirmed to be primary liver cancer of PDDHS and accompanied with ascites were randomly divided into the treated group (n=33) and the control group (n=28). The treated group was treated by XSD combined with chemotherapy by locally applying of DDP via abdominal infusion, while the control group treated by DDP infusion alone. The treatment lasted for two months. The conditions of ascites, quality of life (QOL), survival period, and TCM syndrome after treatment were observed. In the experimental study, the mice models of ascites were grouped and treated to observe the conditions of ascites and their survival period.</p><p><b>RESULTS</b>The short-term total effective rate of the treated group and the control group was 42.4% and 21.4%, the interval of aspirating ascites after treatment was 17.95 +/- 9.63 days and 10.87 +/- 7.76 days, and the 1-year survival rate 33.3% and 14.3%, respectively, significant difference was shown between the two groups in the three parameters (all P < 0.05 ). QOL was improved in both groups with insignificant difference (P > 0.05). Besides, the main symptoms were improved in patients of both groups, especially in the ameliorating of fatigue, abdominal distension, nausea and vomiting. Evaluation on safety of treatment showed that XSD had no obvious toxic and adverse reaction, and so it was safe in use. Experimental study showed that on the two mice models of ascites induced by inoculating two kinds of tumor cell, the effect of XSD was superior to that of the control group in aspects of reducing ascites and prolonging survival period, showing significant difference (P < 0.05).</p><p><b>CONCLUSION</b>Satisfactory short-term efficacy in treating primary liver cancer with ascites of the Pi-deficiency with damp harassment syndrome could be obtained by XSD. Its effect in prolonging survival period was confirmed by experimental study. XSD can also improve the symptoms and QOL of patients, therefore, it is an effective and reliable remedy for treatment of primary liver cancer with ascites.</p>
