Generic Association Analysis on "Prescription-Formula-Dosage-Property" of Tibetan Medicine Based on Partial Order Structure and Property Theory / 中国实验方剂学杂志

Objective:In view of the complexity of the "Prescription-Formula-Dosage-Property" relationship of Tibetan medicine and the outstanding common relationship，it is difficult to reveal the hidden and specific rules of clinical medication of Tibetan medicine. Method:Based on the attribute partial order structure and the vector structure model of "Ro-Nus-Zhu-Rjes"（Taste，Post-Digestive Tastes and Potency），clustering analysis and other methods and software，this study analyzed the "Prescription-Formula-Dosage-Property" relationship of 184 commonly used prescriptions in the 1995 edition of the standards issued by the Ministry of Tibetan medicine（SIMTM）. Result:Among them，the analysis of the relationship between prescription and formula found that 11 prescriptions with the largest common attribute，such as Chebulae Fructus and Carthami Flos，were the key components of classification and compatibility，which could effectively classify the 8 kinds of prescriptions for the treatment of lung disease，tripa disease and blood fever. Among them，the san Yin and auxiliary viscera function prescriptions，such as Sanguotang powder and Liuwei Liangyao powder，had the strongest commonality. According to the analysis of relationship between formula and dosage ，the dosage of Chebulae Fructus，Carthami Flos，pomegranate seed，Phyllanthi Fructus was the highest，which suggested that these drugs were often used as primary drugs，while the Liuwei Liangyao powder，such as Amomi Fructus Rotundus and Tsaoko Fructus，had a higher frequency but a lower dose，which mainly played a role in regulating the overall drug property of the prescription and protecting the viscera. The Tibetan medicine-specific drugs including Moschus，Bovis Calculus，and Zhaxun，which were used in a high frequency but very low dose，had the effect of enhancing the drug property and guiding the affected part. According to the analysis of the relationship between dosage and property，there were many prescriptions belonging to cool nature，accounting for 75.6%. It was found that 67 prescriptions did not conform to the efficacy due to their different dosage. Conclusion:There are many common components and common usages in Tibetan medicine prescriptions. If these common associations are not treated，it will lead to the result that all diseases take these common associations as the core，but the hidden key factors cannot be solved. Therefore，it is necessary to pay attention to sensitivity and specificity at the multi-dimensional level of "prescription-formula-dosage-property"，so as to reveal the clinical medication thought of Tibetan medicine more effectively.

Construction of Tibetan Medicine Prescription Database for Treating "Gnyan-rims" and Analysis of Their Medication Law Based on Python Language / 中国实验方剂学杂志

Objective:To construct the database of Tibetan medicine prescriptions for "Gnyan-rims" disease， and to explore the invisible medication law of Tibetan medicine in the treatment of "Gnyan-rims" disease， such as prescription compatibility and combination of drug properties. Method:The prescriptions for treating "Gnyan-rims" were retrieved from four Tibetan medical literatures such as <italic>The Four Medical Tantras</italic>，<italic> Kong-sprul-zin-tig，</italic> <italic>Phyag-rdor-gso-rig-phyogs-bsgrigs</italic> and <italic>Sman-sbyor-lag-len-phyogs-bsgrigs</italic>， and the database was constructed under Python code， and the Apriori algorithm and the vector structure model of taste property flavor transformation were used for analysis. Result:According to the characteristics of Tibetan medicine prescription data， with six fields of prescription name， formula， dosage， efficacy， source and original text as the core， a Tibetan medicine treatment "Gnyan-rims" prescription database with functions of cleaning， searching and exporting was established. A total of 7 602 prescriptions were included in the database， among which 598 prescriptions had therapeutic effects of "Gnyan" and "Rims". The results of compatibility analysis showed that Shexiang， Hezi， Honghua， Mukuer Moyao， Tiebangchui， Tianzhuhuang and Bangga were the most frequently used drugs， while the correlation degrees of Shexiang-Mukuer Moyao， Honghua-Tianzhuhuang， Shexiang-Hezi and Shexiang-Tiebangchui were the strongest， and all the drug composition of Wuwei Shexiang pills appeared in the top ten correlations. According to the property analysis of 40 prescriptions containing high-frequency drugs， 19 prescriptions were found to have excessive bitter taste， followed by 9 prescriptions such as Sanchen powders with excessive sweetish taste， and the ratios of sweetish and bitter tastes in six tastes were >35%. The total of sweetish and bitter prescriptions accounted for 70% of the total prescriptions. Among the three flavors， the bitter flavor was the most abundant. The cool effect， dull effect and heavy effect were prominent among the seventeen effects. Conclusion:The prescription database of Tibetan medicine for "Gnyan-rims" can promote the high-quality development of research on prevention and treatment of plague with ethnic medicine. Tibetan medicine treatment of "Gnyan-rims" focuses on the composition of Wuwei Shexiang pills， with the property combination of "cool-bitter and sweet-bitter flavor-cool， dull and heavy"， which mainly treats diseases such as "heat sharp light-mkhris pa-heat". These studies can provide data basis and theoretical reference for the selection of Tibetan medicine prescription and its composition for treating plague.

Advances in Research on Different Compatibility Ratios of Coptidis Rhizoma-Evodia Fructus / 中国实验方剂学杂志

Coptidis Rhizoma-Evodia Fructus is a classic herb pair in traditional Chinese medicine prescriptions, the famous prescription is called Zuojinwan, which comes from Danxi Xinfa, is composed of Coptidis Rhizoma-Evodia Fructus (6∶1). In this formula, Coptidis Rhizoma has the effect of clearing heat and drying diuresis, purging fire to remove toxin and clearing heart. Evodia Fructus has the effects of expelling cold and alleviating pain, checking upward adverse flow of Qi tostop vomiting, and assisting yang to stop diarrhea. Coptidis Rhizoma has the properties of bitter and cold, and Evodia Fructus has the properties of pungent and calidus. Pungent drugs have divergent effects, and bitter drugs have sedimentation effect, when used in combination, they can clear the liver and purge fire, calm the adverse-rising energy and stop vomiting. On the basis of Zuojinwan, Coptidis Rhizoma-Evodia Fructus medicine has derived different compatibility ratios. Different ratios are different in terms of efficacy, usage, clinical application. Although with the application of modern analytical instruments and the development of molecular pharmacology theory, the chemical constituents and Pharmacological effects of Coptidis Rhizoma and Evodia Fructus have been fully studied, as to the principle of compatibility, and the study of pharmacological effects and chemical constituents after the compatibility of the two drugs in different proportions, there is still no comprehensive system summary. This article makes a systematic and comprehensive explanation of Coptidis Rhizoma-Evodia Fructus from the aspects of famous literature, chemical composition, pharmacological effects and clinical applicationthrough querying literature and ancient books. In order to make this herb pair more standardized, and provide reference materials for further research and development for this herb pair.

Study of novel coating strategy for coronary stents: simutaneous coating of VEGF and anti- CD34 antibody / Estudo da nova estratégia de revestimento para stents coronários: revestimento simultâneo de VEGF e anticorpo anti-CD34

Abstract Introduction: Intravascular coronary stenting has been used in the treatment of coronary artery disease (CAD), with a major limitation of in-stent restenosis (ISR). The 316 stainless steel has been widely used for coronary stents. In this study, we developed a novel coating method to reduce ISR by simultaneously coating vascular endothelial growth factor (VEGF) and anti-CD34 antibody on 316L stainless steel. Methods: Round 316L stainless steel sheets in the D-H group were polymerized with compounds generated from condensation reaction of dopamine and heparin using N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide (EDC) and N-hydroxysuccinimide (NHS). Sixteen sheets from the D-H group were further immersed into 1ug/ml VEGF165 and 3mg/ml heparin sodium one after another for 10 times, and named as the D-(H-V)10 group. Eight sheets from the D-(H-V)10 group were coated with anti-CD34 antibody and termed as the D-(H-V)10-A group. Immunofluorescence assay and ELISA were used to evaluate whether the 316L stainless steel disks were successfully coated with VEGF and anti-CD34 antibody. Results: The results of immunofluorescence assay and ELISA showed that VEGF could be detected in the D-(H-V)10 and D-(H-V)10-A group, suggesting the steel sheets were successfully covered with VEGF. Anti-CD34 antibody could only be observed in the D-(H-V)10-A group, which was the only group coated with CD34 antibody. Both results suggested that the 316L stainless steel sheets were successfully coated with VEGF and anti-CD34 antibody. Conclusion: Our study developed a method to simultaneously coat VEGF and anti-CD34 antibody to stainless metal steel. This research serves as a fundamental role for a novel coating strategy. .

Resumo Introdução: O stent coronário intravascular tem sido utilizado no tratamento de doença arterial coronária, com uma maior limitação de restenose intra-stent (RIS). O aço inoxidável 316 tem sido amplamente utilizado para stents. Neste estudo, foi desenvolvido um novo método de revestimento para reduzir a RIS para revestir simultaneamente o fator de crescimento endotelial vascular (VEGF) e anti-CD34 em aço inoxidável 316L. Métodos: Placas de aço inoxidável 316L redondas no grupo DH foram polimerizadas com compostos gerados a partir da reacção de condensação de dopamina e heparina utilizando N- (3-dimetilaminopropil) -N'-etilcarbodiimida (EDC) e N-hidroxissuccinimida (NHS). Dezesseis folhas a partir do grupo DH foram ainda imersas em 1 ug/ml de VEGF 165 e 3 mg/ml de heparina sódica, um após outro por 10 vezes, sendo denominado como o grupo D-(HV)10. Oito folhas de D-(HV)10 foram revestidas com anticorpo anti-CD34 e denominado como grupo D-(HV)10-A. Testes de imunofluorescência e ELISA foram usados para avaliar se os discos de aço inoxidável 316L foram revestidos com sucesso com VEGF e anticorpo anti-CD34. Resultados: Os resultados dos testes de imunofluorescência e ELISA mostraram que o VEGF pôde ser detectado nos grupos D-(HV)10 e D-(HV)10-A, evidenciando que as chapas de aço foram cobertas com VEGF com sucesso. O anticorpo anti-CD34 podia apenas ser observado no grupo D-(HV)10-A, o único grupo revestido com anticorpo CD34. Ambos os resultados sugerem que as chapas de aço inoxidável 316L foram revestidas com sucesso com VEGF e anticorpo anti-CD34. Conclusão: Nosso estudo desenvolveu um método para revestir simultaneamente VEGF e anti-CD34 de aço inoxidável. Esta pesquisa tem um papel fundamental para a nova estratégia de revestimento. .

Association of CASP3 gene single nucleotide polymorphisms with Kawasaki disease in Chinese children patients / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>The minor allele T of rs113420705 (C/T) in caspase-3 gene (CASP3) has been found to significantly increase the risk of Kawasaki disease (KD) and complicate coronary artery lesions (CALs) in Japanese children. In this study, we have explored association of single nucleotide polymorphisms (SNPs) of CASP3 gene and clinic phenotypes of KD.</p><p><b>METHODS</b>A total of 238 unrelated KD patients and 364 healthy controls with matched age, gender and ethnic origins were recruited. Genotypes of the 3 SNPs were determined with PCR-restriction fragment length polymorphism (PCR-RFLP) and DNA sequencing. Allelic, genotypic and haplotypic frequencies were compared between patients and controls, patients with and without CALs, and patients resistant to and responsive to intravenous immunoglobulin (IVIG) treatment.</p><p><b>RESULTS</b>The T allele and T carriers of rs113420705 were significantly more common in KD patients than controls. A significant difference was also detected in haplotype distribution between patients and controls, where two haplotypes involving the T allele of rs113420705 showed higher frequencies in the patient group. Allelic and genotypic frequencies of the 3 SNPs were similar between patients with and without CALs and those resistant to and responsive to IVIG treatment.</p><p><b>CONCLUSION</b>Our results suggested that CASP3 probably plays an important role in KD. The T allele of rs113420705 may provide a useful marker for KD susceptibility, although no association between this SNP and clinical prognosis and treatment effect of KD has been found among the selected Chinese children patients.</p>

Association study of a functional SNP rs28493229 of ITPKC gene and Kawasaki disease in a Chinese population / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>Kawasaki disease (KD) is a form of acute multi-systemic vasculitis with unknown etiology. It is the leading cause of acquired heart disease in children due to the frequent occurrence of coronary artery lesions (CALs). Recently, a C allele of rs28493229 (G/C) in inositol 1,4,5-trisphosphate 3-kinase C (ITPKC) gene was found to significantly increase the risk for KD/CALs in Japanese population. It is important to confirm such finding in Chinese population to enable prognosis and personalized therapy for KD.</p><p><b>METHODS</b>A case-control study was performed. The patient group has included 206 unrelated patients with KD, and the control group included 285 age, gender and ethnically matched children who never had KD. Genotyping of rs28493229 was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and DNA sequencing. The allele, genotype and C allele carrier frequencies were compared between the two groups, patients with or without CALs, and patients who were resistant or responsive to (intravenous immunoglobulin, IVIG) treatment.</p><p><b>RESULTS</b>Frequency of the C allele of rs28493229 was significantly lower in both groups than that in the Japanese population (P< 0.01). No significant difference was detected between the two groups in terms of allele, genotype and C carrier of rs28493229 frequencies. Such frequencies were also similar between patients with or without CALs, resistant or responsive to IVIG treatment.</p><p><b>CONCLUSION</b>Our study has failed to prove any association between rs28493229 and KD/CALs in Chinese patients, which indicated that the C allele of rs28493229 may not be used as a molecular marker for determining KD susceptibility, prognosis and effect of treatment. The much lower frequency of C allele does not support its significance in the occurrence of KD/CALs in Chinese population. It is still necessary to find functional SNPs in ITPKC gene which is associated with KD/CALs in Chinese population.</p>

The Assessment of Bladder and Urethral Function in Spinal Cord Injury Patients / 华中科技大学学报（医学）（英德文版）

The correlation between the anatomic site of spinal cord injury and real-time conditions of bladder and urethral function was assessed in order to provide a reasonable basis for the clinical treat-ment of neurogenic bladder. A total of 134 patients with spinal cord injuries (105 males, 29 females;averaged 34.1 years old) were involved in this retrospective analysis, including urodynamic evaluation,clinical examination and imaging for anatomical position, and Bors-Comarr classification. The associa-tions between the levels of injury and urodynamic findings were analyzed. The results showed that mean follow-up duration was 16.7 months (range 8-27 months). Complete spinal cord injuries occurred in 21 cases, and incomplete spinal cord injuries in 113 cases. Of the 43 patients with upper motor neu-ron (UMN) injuries, hyperreflexia and (or) detmsor sphincter dyssynergia were demonstrated in 30 (69.8%), 31 (72.1%) suffered low bladder compliance (less than 12.5 mL/cmH2O), 28 (65.1%) had high detrusor leak point pressures (greater than 40 cmH2O), and 34 (79.1%) had residual urine. Of the 91 pa-tients with lower motor neuron (LMN) injuries, areflexia occurred in 78 (85.7%), high compliance in 75 (82.4%), low leak point pressures in 80 (87.9%), and residual urine in 87 (95.6%), respectively. The as-sociations between the anatomical site of spinal cord injury and urodynamic findings were ill defined. In patients with spinal cord injury, this study revealed a significant association between the level of injury and the type of voiding dysfunction. The anatomical site of spinal cord injury can not be predicted in real-time condition of bladder and urethral function. Management of neurogenic bladder in patients with spinal cord injury must be based on urodynamic findings rather than inferences from the neurologic evaluation.
