ObjectiveTo investigate expression distribution of mutant connexin 32 (Cx32) protein in human endothelial cells in patients with X-linked Charcot-Marie-Tooth disease type 1 ( CMTX1 ) .MethodsNerve biopsies were performed in 3 patients with CMTX1 and in 3 non-CMTX1 controls. Cx32 mutations of c. 379A ＞ T( I127F), c. 533A ＞ G(D178G) and c. 590C ＞ T(A197V) were identified in these 3 patients respectively.Immunofluorescent (IMF) staining of nerve blood vessel was processed with antibodies against Cx32, Yon Willebrand factor and Cx40. The mutant Cx32 was constructed in pEGFP-N plasmid (pEGFP-N1-Cx32) and was transfected in HeLa cells. Cx32 and GRP78, a marker of endoplasmic reticulum ( ER), were stained by IMF in HeLa cells to investigate expression of mutant Cx32. ResultsIn 3 control cases, Cx32 was visualized by IMF staining as dots along gap junction of vascular endothelial cells,and it was coexisted with Cx40.However, immunoreactivity of Cx32 in 3 patients was predominantly decreased and was not located in endothelial gap junction. The transfection of 3 Cx32 mutants into HeLa cells demonstrated thepathogenic changes.The cells withthemutationc. 379A ＞T found Cx32 accumulations in the cytoplasm; the cells with mutation c. 533A ＞G showed few staining positive dots surrounding the nuclear and the cells with c. 590C ＞ T showed dot-like expression of Cx32 both in the cytoplasmicand cell membrane. The mutant Cx32 was not overlapped with expression of the marker of ER.ConclusionsMutant Cx32 might cause dysfunction of endothelial gap-junctions due to the abnormal expression of Cx32 in level and location in the vascular endothelial cells of CMTX1 patients.

ObjectivesTo report pathological and genetic features of 6 Chinese families with Xlinked Charcot-Marie-Tooth disease type 1 ( CMTX1 ).Methods The index cases from 6 families with CMTX1 are males with onset of disease between 11 and 24 years old.All of them had distal leg muscle weakness,accompanied with areflexia and sensory loss in the feet.Additionally,the index 1 presented with recurrent encephalopathy and the index case 5 with cerebellar ataxia.Peripheral neuropathy was found in 12 family members,while other 7 members showed talipescavus and hyporeflexia.Sural nerve biopsies were performed in all index cases.Connexin 32(Cx32) gene was analyzed in the index cases,8 affected and 10unaffected family members as well as 50 healthy women control subjects.ResultsMild to moderate loss of myelinated fiber with axonal degeneration and regeneration clusters were found in all index cases. Thin myelin fibers were found in 5,small onion bulbs in 3 and inflammatory infiltrates in 2.Five novel mutations (I20T,I127F,D178G,A197V,403_404insT) and one L10L synonymous mutation were detected in the 6index cases and their affected family members.The same mutations,in heterozygous state,were detected in 4 female family members without clinical symptoms,but not found in 6 male unaffected family members.The same mutations were not found in healthy control subjects.ConclusionsThe CMTX1 patients in our study present predominantly axonal lesions.Frequent novel Cx32 gene mutations indicated that private mutations may be common in Chinese CMTX1 patients.

The levels of IL-6 (1.15 ±0.24 μg/L vs. 19.64 ±4.16 μg/L; t=9.527, P<0.001) and TNF-α(1.43 ±0.31 μg/L vs.26.17 ±4.32 μg/L; t=9.816, P<0.001) in the arterial wal in the control group were significantly lower than those in the intracranial aneurysm group. Conclusions The expression of IL-17 receptor in the arterial w al , the proportion of the Th17 cels and IL-17 level in peripheral blood were increased in patients with intracranial aneurysms. Immune inflammation may be involved in the formation of intracranial aneurysm.

This paper was aimed to discuss the application of content management system (CMS) Drupal in Chinese medicine information fusion. The modular functionality, scalability and strong management capabilities of Drupal can effectively manage and reasonably present information resources of Chinese medicine, which extended the application of Chinese medicine information fusion. Regarding CMS Drupal as the carrier of Chinese medicine information fusion, the Chinese medicine information fusion method can be used in the collection, organization and demonstration of Chinese medicine information in the platform. As one of network tools for Chinese medicine information fusion, Dru-pal will play its powerful function in content management and information publishing with the virtual technology. It will also enrich Chinese medicine information fusion, and promote the spread of Chinese medicine knowledge.

Salvia miltiorrhiza is a traditional Chinese medicine (TCM) and is widely used as a clinically medication for its efficiency in treating cardiovascular disease. Due to TCM is a comprehensive system, the mechanism of S. miltiorrhiza treating cardiovascular disease through integrated multiple pathways are still unclear in some aspects. With the rapid progress of bioinformatics and systems biology, network pharmacology is considered as a promising approach toward reveal the underlying complex relationship between an herb and the disease. In order to discover the mechanism of S. miltiorrhiza treating cardiovascular disease systematically, we use the auxiliary mechanism elucidation system for Chinese medicine, built up a molecule interaction network on the active component targets of S. miltiorrhiza and the therapeutic targets of cardiovascular disease to offer an opportunity for deep understanding the mechanism of S. miltiorrhiza treating cardiovascular disease from the perspective of network pharmacology. The results showed that S. miltiorrhiza treating cardiovascular disease through ten pathways as follows: improve lipid metabolism, anti-inflammation, regulate blood pressure, negatively regulates blood coagulation factor and antithrombotic, regulate cell proliferation, anti-stress injury, promoting angiogenesis, inhibited apoptosis, adjust vascular systolic and diastolic, promoting wound repair. The results of this paper provide theoretical guidance for the development of new drugs to treat cardiovascular disease and the discovery of new drugs through component compatibility.

To propose a formula method of medicated diet based on medicinal property combination patterns in this paper under the context of lack of innovation in medicated diets. By analyzing the property combination patterns of traditional Chinese medicine and commonly used foods recorded in the pharmacopoeia, medicated diet formulae were optimized by using the greedy algorithm, with the property combination patterns of classical formulae based on the syndrome differentiation and treatment. In this paper, the Baihu Rensheng decoction, which is a classical formula for treating lung and stomach heat-derived diabetes, was taken for example in the formula design. As a result, totally 18 medicated diet formulae were developed and proved to be rational in the analysis on traditional Chinese medicines and nutriology. This method expands the way of thinking for personalized diet therapies and provides theoretical basis the industrial development and clinical application of medicated diets.

The prescription combinations of traditional Chinese medicine (TCM) focuses on the taste and channel tropism, the Qi movement, as well as the compatibility according to multiple combination principles and medicinal property and flavor combination of several traditional Chinese medicines. With the in-depth study on the prescription compatibility, researchers have realized that the medicinal property theory is the core of TCM combinations. However, there is no definite method for combinations based on medicinal properties. In this paper, the authors put forward an method for designing prescription combinations based on bipartite graph and the greedy algorithm. With the medicinal property combinations of Siweilurong Pills for example, the authors proved this method could provide ideas for quickly choosing herbal medicines for prescription combinations, and discussed the prospect of this method in substituting previous and endangered herbal medicines and banned medicinal materials.
