OBJECTIVETo study whether the analgesis of oxymatrine (OMT) affects N-type voltage-gated calcium channels (VGCCs).

METHODSTotally 45 mice were randomly divided into the sham-operation group, the model group [established by partial sciatic nerve ligation (PSNL)] , and the OMT treatment group according to random digit table, 15 in each group. The dorsal root ganglions (DRG) were separated in PSNL pain model mice. Intracellular calcium concentration ([Ca2+]i) was determined with Fluo-3 AM immunofluorescent probe in cultured DRG neurons. Different protein expression levels of N-type (Cav2. 2) and L-type ( Cav1. 3) among VGCCs from brain and DRG tissues were detected with Western blot.

RESULTSCompared with the sham-operation group, [Ca2+]i, increased in cultured DRG neurons (P <0. 05) , protein expression levels of Cav2. 2 in the brain tissue increased (P <0. 05), protein expression levels of Cav2. 2 in DRG tissues decreased in the model group (P <0. 01). Compared with the model group, [Ca2+]i, decreased in cultured DRG neurons (P < 0. 05), protein expression levels of Cav2. 2 in the brain tissue decreased (P <0. 01), protein expression levels of Cav2. 2 in DRG tissues increased in the OMT treatment group (P <0. 01). There was no statistical difference in Cav1. 3 expressions in cultured DRG neurons and the brain (P >0. 05).

CONCLUSIONAnalgesic effect of OMT might be related to Cav2. 2 channel mediated calcium ion flux.

Through collecting and collating the development process of traditional Chinese medicine dispensing, the development of modern Chinese medicine dispensing on the basis of experience could be promoted. "Heyaofenji", "Hehe", " Heji" in ancient Chinese medicine, herbal medicine literature and law were collected, and then things were sorted out according to traditional Chinese medicine dispensing theory, skills and legal norms. Firstly, "Tang Ye Jing Fa" is the earliest book which marks the rudiment of traditional Chinese medicine dispensing. Secondly, traditional Chinese medicine dispensing theory formed in "Shen Nong's herbal classic". Thirdly, Zhang Zhongjing's "Treatise on Febrile Diseases" marked the formation of Chinese medicine dispensing skills. Lastly, Provisions in Tang Dynasty law marks the development of traditional Chinese medicine dispensing.

OBJECTIVETo explore the analgesia of oxymatrine (OMT) affecting high voltage-dependent calcium channels (HVDCCs) and GABA release under neuropathic pain condition.

METHODSTotally 66 C57BL/6 mice were randomly divided into the sham-operation group, the model group, and the OMT group, 22 in each group. Neuropathic pain models were established by partial sciatic nerve ligation (PSNL). Hind paw plantar mechanical response threshold (MWT) was measured by up-and-down method with Von-Frey filament. mRNA expression of HVDCCs in brains and spinal cords was detected with Real-time PCR and concentration of GABA was determined using ELISA kit.

RESULTSCompared with day 0, the left hind paw MWTwas decreased on day 7, 10, and 14 in the model group (P < 0.05). Compared with the sham-operation group, the left hind paw MWT was significantly reduced in the model group on day 7 (P < 0.05). The MWT of PSNL ipsilateral hind paw was decreased on day 7 before OMT administration, when compared with day 0 (P < 0.05), and increased after OMT administration (P < 0.05). Compared with the sham-operation group, mRNA levels of Cav1.2, Cav1.3, Cav2.1, and Cav2.3 in brain tissues were increased and those of Cav2.2 were decreased significantly in the model group (P < 0.05). In spinal cord tissues, mRNA levels of Cav1.2 and Cav1.3 were increased, but those of Cav2.1, Cav2.2, and Cav2. 3 were decreased significantly in the model group, when compared with those of the sham-operation group (P < 0.05). Compared with the model group, mRNA levels of Cavl.2, Cavl.3, Cav2.1, and Cav2. 3 in brain tissues were decreased, and those of Cav2.2 were increased significantly in the OMT group (P < 0.05). In spinal cord tissues of the OMT group, mRNA levels of Cav1.3 decreased and those of Cav2.1, Cav2.2, and Cav2.3 increased significantly with statistical difference, when compared with those of the model group (P < 0.05). Compared with the sham-operation group, GABA levels in brain tissues decreased in the model group (P < 0.05). Compared with the model group, GABA levels in brain tissues increased in the OMT group (P < 0.05). There was no statistical difference in GABA levels of spinal cord tissues among these groups (P > 0.05).

CONCLUSIONSOMT had analgesic effect on neuropathic pain, which might be probably related to HVDDCs. Cav2.2 might directly affect GABA release.

Based on the results of the Kirkwood high-dose interferon alpha-2b (HDI) adjuvant therapy trial of the Eastern Cooperative Oncology Group 1684, the US Food and Drug Administration (FDA) approved HDI as the postoperative adjuvant therapy for high-risk melanoma. Unfortunately, controversies continue regarding the use of interferon (IFN) as adjuvant therapy for melanoma owing to the inconsistent results of subsequent trials. Numerous trials of adjuvant interferon therapy demonstrated a benefit in terms of relapse-free survival (RFS), but without confirmed significant effect on overall survival (OS). The optimal timing, dose, and type of interferon are not yet defined. Therefore, adjuvant interferon treatment is preferentially applied in the randomized clinical trials in specialized centers. Decisions about the appropriateness of adjuvant interferon alfa-2b treatment for patients should be made on an individual basis, after discussion with the patient, including an explanation of the potential benefits and side effects of interferon therapy. Moreover, we also need to use available regimens reasonably, seek feasible and predictable prognostic factors to serve patients with individualized therapy.

Objective To identify and rename one strain stored in National Center for Medicine Culture Collections ( CMCC) and used for tracheitis vaccine production. Methods The test strain CMCC (B)29108 and the type strain DSM30007T were cultured on NA medium. Characteristics in morphology, physiology, biochemistry and fatty acid profile were compared between the two strains. Phylogenetic analysis was based on 16S rRNA and rpoB gene sequences, together with the DNA-DNA hybridization assay. Results A Comparative analysis of a partial sequence of the 16S rRNA gene sequence revealed that the CMCC( B) 29108 strain was closed to the Acinetobacter species and showed the highest similarity with the type strain Acinetobacter baumannii DSM30007T. Moreover, the CMCC(B)29108 strain was highly similar to type strain DSM30007T in morphology, physiology, biochemistry and fatty acid profile. On the phylogenetic tree based on 16S rRNA and rpoB gene of all Acinetobacter members, the CMCC(B)29108 strain steadily clustered into one independent branch only with the DSM30007 T strain with a DNA-DNA hybridization value of 100%. Conclusion The CMCC(B)29108 strain that is one of the strains used for the production of tracheitis vac-cine should be assigned to the species of Acinetobacter baumannii based on its phenotypic, phylogenetic and chemotaxonomic characteristics.
