Pharmacological method state is a method to explain the principle of Chinese herb according to its external phenomenon such as shape, color, texture, features, and so on. The natural attribute of Chinese herb include shape, color, texture, smell, harvesting time, medicinal parts, chemical components, and so on. Though both of them have different key points, the natural attribute of Chinese herb can also be used to explain its medicinal mechanism. Therefore, the correlation research between pharmacological method state and the natural attribute of Chinese herb has some significance.

UNLABELLEDOBJECTIVE : To study the anti-atherosclerotic mechanism of bear bile powder (BBP) in Shexiang Tongxin Dripping Pill (STDP) , and to provide scientific evidence for treating atherosclerosis (AS) by its therapeutic characteristics of cool resuscitation.

METHODSAS model was duplicated using ApoE-/- gene knocked mice fed with high-fat diet. Thirty ApoE-/- deficient male mice were divided into four groups according to body weight using random digit table, i.e., the model group (A, n =9), the STDP group (B, n=E7), the STDP without BBP group (C, n =7), and the BBP group (D, n =9). Besides, another 9 C57BL/6J male mice of the same age were recruited as a normal control group (E). All mice in Group B, C, and D were respectively administered with corresponding drugs (30, 30, and 0. 33 mg/kg) by gastrogavage. Equal volume of normal saline was administered to mice in Group A and E. All medication lasted for 8 successive weeks. Serum levels of inflammatory cytokines such as interleukin 2 (IL-2), interleukin 6 (IL-6), tumor necrosis factor a (TNF-α), interferon y (IFNγ), and oxidized low-density lipoprotein (ox-LDL) were measured by ELISA. Serum levels of malondialdehyde (MDA), activities of glutathione (GSH) and superoxide dismutase (SOD) were determined using biochemical assay. Contents of reactive oxygen species (ROS) in the aortic root was detected by dihydroethidum (DHE) fluorescent probe. Expression levels of microRNAs (such as miR-20, miR-21, miR-126, and miR-155) were detected by real-time PCR.

RESULTSThe fluorescence intensity of the aorta was obviously enhanced in Group A. But it was obviously attenuated in Group B, C, and D, and the attenuation was the most in Group B. Compared with Group E, serum levels of IL-2, IL-6, TNF-α, IFN-γ, oxLDL, and MDA all increased (P <0. 01), GSH contents and SOD activities decreased (P <0. 01), expression levels of miR-126, miR-21, and miR-155 in aorta increased (P <0. 01), and the expression level of miR-20 decreased in Group A (P<0. 01). Compared with Group A, serum levels of IL-2, IL-6, TNF-α, IFN-γ, oxLDL, and MDA were all down-regulated (P <0. 01), GSH contents and SOD activities were up-regulated (P <0. 01), expression levels of miR-126, miR-21, and miR-155 in aorta were down-regulated in Group B, C, and D (P <0. 01). The expression level of miR20 was up-regulated in Group B and D (P <0. 01). Compared with Group B, serum levels of IL-2, IL-6, TNF-α, IFN-γ increased (P <0.01); GSH contents and SOD activities decreased, levels of MDA and oxLDL increased (P <0. 01) in Group C and D. Expression levels of miR-20 and miR-155 were down-regulated in Group C and D (P <0. 01).

CONCLUSIONSSTDP played roles in significantly regulating inflammatory factors and oxidative stress factors. Its mechanism might be possibly associated with regulating expressions of miR-126, miR-21, miR-155, and miR-20 in aorta. BBP played significant roles in STDP.

s: The onset of Crohn’s disease (CD) is the interaction of environment, heredity, infection, immune and other factors. It is also closely related to abnormal immune functions. Without special treatment, CD is identified as a modern refractory disease. By syndrome differentiation and treatment, traditional Chinese medicine (TCM) can effectively relieve disease conditions, improve the quality of life and reduce side effects of modern medication. The core compatibility ofBai-Zhu andFu-Ling can reinforce spleen-qi and dispel dampness, which met the common pathogenesis of CD. Therefore, the combination is comprehensively used in the compound prescription. Our previous study found thatBai-Zhu Fu-Ling decoctioncan reduce the vasoactive intestinal peptide (VIP) of animal model of spleen-qi deficiency, downregulate VIP receptors, decrease the affinity of VIP receptors and improve animal model’s sIgA. To further clarify the effects about neurotransmitters and their correlation with the immune system in the pathogenesis of CD and the intervention mechanism treated by different proportional compatibility ofBai-Zhu Fu-Ling decoction, we studied influences of the decoction on related transmitters of nerve- immune network and functions of receptors, as well as cytokine secretion and signal transduction of TLR4-NF-κB. Our studies can provide references and foundations to further explore TCM treatment of CD.

Objective To analyze the differential expressions ofmicroRNAs in patients with methylmalonic acidemia (MMA) and explore the expression rule ofmicroRNAs in MMA pathogenesis primarily to find the new biomarkers and therapeutic evaluation index of MMA represented by microRNAs.Methods Ten patients,admitted to our hospitals and diagnosed as having delayed onset vitamin B12 valid MMA from August 2011 to June 2013,were chosen as experimental group (MMA group);and their 8 healthy relatives were chosen as negative control group (NC group).Plasma microRNAs were routinely extracted and filed,and samples quality was evaluated with real-time quantitative PCR;microarray gene chip was employed to detect the expression levels ofmicroRNAs;R software of prediction analysis ofmicroarrays (PAM) was used to filter differentially expressed miRNAs.Results The results of GC/MS showed that the urine methylmalonic acid zoom ratio of MMA group was significantly higher than that of NC group.And the urine methylmalonic acid zoom ratio of MMA group had remarkable difference between before and after treatment.Real-time PCR showed the RNAs extracted from plasma samples conformed to the requirement of experiment and could be delivered to downstream chip experiment.The chip statistical analysis suggested that there were many micrornas enjoying significant differences between MMA group and NC group (P＜0.05),and differences in MMA group before and after treatment (P＜0.05).The resluts of R software of PAM indicated that mir-483 and mir-144 were strongly raised in MMA group as compared with those in NC group (P＜0.05),while mir-151,mir-30 and mir-146 were remarkably reduced in MMA group as compared with those in NC group (P＜0.05).Conclusion There are several abnormal expressions of plasma circulation microRNAs in patients with methylmalonic acidemia;the plasma circulation microRNAs might be biomarkers of methylmalonic acidemia.

Objective A/H1N1(pdm09) viruses were the dominant strains in Shanghai during 2018-2019 influenza surveillance year.This study is to provide a scientific reference for clinical drug use by investigating the susceptibility of A/H1N1(pdm09) viruses to neuraminidase inhibitors(NAIs). Methods Sixty strains of A/H1N1(pdm09) viruses were randomly selected for testing the susceptibility and drug resistance to Oseltamivir and Zanamivir by means of neutaminidase inhibition and neuraminidase (NA) gene sequencing. Results The 60 epidemic strains all proved to be susceptible to Oseltamivir and Zanamivir and the susceptibility was not observed to be decreased or remarkably decreased.In genetic sequencing, NA was not observed to present amino acid mutation at the key sites and auxiliary sites in catalytic activity, which confirmed the results of the phototypic detection of neuraminidase inhibition. Conclusion The subtype influenza viruses A/H1N1(pdm09) circulating in Shanghai during 2018-2019 surveillance year are still sensitive to NAIs, which provides a scientific reference for clinical use of drugs.However, we monitored only a number of strains and think that the work monitoring antiviral susceptibility should be continued with the wide use of the drugs.

OBJECTIVETo study the surgical indications, approaches and the clinical results of the total spondylectomy and instrumentation reconstruction in the treatment of cervical spinal tumor.

METHODSFrom October 1998 to October 2003, 39 patients with lower cervical bone tumors, including 34 cases with primary tumor and 5 cases with metastatic tumor, were admitted and operated on with total spondylectomy. The patients underwent anteroposterior total spondylectomy including anterior cervical plating, titanium mesh reconstruction and posterior instrumentation based on the location of tumor lesions in the lower cervical spine. One vertebral level total spondylectomy was performed in 29 cases, two level in 7 cases and three level in 3 cases.

RESULTSThe postoperative follow-up ranged from 6 months to 4 years. A majority of patients achieved good results postoperatively. Nineteen cases had complete relief of neurological status. One patient died of multiple metastases and systemic failure 24 months later. One case with malignant neurilemmoma developed local recurrence one year postoperatively.

CONCLUSIONAnteroposterior total spondylectomy and reconstruction can reduce local recurrence, improve neurological function and increase operation therapeutic effect. Meanwhile, the technique of cervical total spondylectomy carries relatively greater risks and should be more attention to the operation indication.

OBJECTIVETo study the influence of Radix aconiti lateralis preparata and Rhizoma zingiberis, two species of Chinese medicinal herbs with hot property, on energy metabolism and gene expression spectrum, and to analyze the possible mechanism of their effects.

METHODSForty-eight specific pathogen free Wistar rats were randomly divided into a Radix aconiti lateralis preparata group, a Rhizoma zingiberis group, and a control group. They were intragastrically treated with concentrated decoction of Radix aconiti lateralis preparata, Rhizoma zingiberis and normal saline respectively for 20 days. Toe temperature (TT), energy intake (EI), digestible energy (DE), and metabolizable energy (ME) were measured. The content of adenosine triphosphate (ATP) and energy charge (EC) in hepatic tissue were measured with high performance liquid chromatography (HPLC). The activity of ATPase and succinate dehydrogenase (SDH) in the liver were detected with chemical colorimetry. The gene expression in the liver was detected with Illumina's rat Ref-12 gene array. The differential expression genes were selected, annotated and classified based on Gene Ontology (GO). Real-time quantitative reverse-transcriptase PCR (Q-RT-PCR) was used to test the accuracy of results.

RESULTSCompared with the control group, the TT on the 10(th) day after the beginning of administration and ATP in the Radix aconiti lateralis preparata and Rhizoma zingiberis groups increased significantly (P<0.05). EI/body mass (BM), DE/BM, ME/BM, the hepatic EC and the activity of Na(+)-K(+)-ATPase, Ca(2+)-Mg(2+)-ATPase and SDH of liver increased significantly only in the Radix aconiti lateralis preparata group (P<0.05). There were 592 differential expression genes in the Radix aconiti lateralis preparata group and 1 159 in the Rhizoma zingiberis group compared with the control group. Among the differential expression genes, genes related to metabolic processes were the most significant based on GO analysis. There were 337 strips of gene differential expression in common in both Radix aconiti lateralis preparata and Rhizoma zingiberis groups compared with the control group.

CONCLUSIONSHerbs with hot property such as Radix aconiti lateralis preparata and Rhizoma zingiberis could improve the energy metabolism in rats, through influencing the metabolic process of sugar, lipid, and amino acid. It could also promote the production, storage, and utilization of energy by regulating the gene expression related to metabolism, which may be the main molecular mechanism of warming yang and dispelling cold for the treatment of the cold syndrome according to Chinese medicine theory.
