Objective To study the diagnostic and distinguishing diagnostic value in primary hepatic carcinoma (PHC)and metastatic hepatic carcinoma (MHC)by the serum sialic acid (SA)detection.Methods During January 2012 to June 2014, 100 cases of patients with PHC,91 cases of patients with MHC,155 cases of benign liver disease patients,and 139 healthy people in Wuyi Traditional Chinese Medicine Hospital were included into the study.The concentration of serum SA and AFP were detected by chemical enzymatic method and chemiluminescence method,SPSS1 9.0 was used to analysis the results.Re-sults The concentration of serum SA in PHC patients (701.08±189.33 mg/L)were significantly higher than benign liver disease patients (588.38±98.51 mg/L)and healthy people (572.37±89.13 mg/L),there was statistical significance (P=0.000),the significantly statistical differences were also in MHC (790.20±162.29 mg/L)and PHC patients (P=0.027). Serum SA in the diagnosis of MHC sensitivity,specificity and AUC were 84.6%,85.2% and 0.895,compared with serum AFP (sensitivity 22.2%,specificity 29.6% and AUC 0.301)had statistically significance (P=0.000).Conclusion The se-rum SA has important clinical significance in the diagnosis and distinguishing diagnosis of PHC and MHC.

Objective To study the diterpene alkaloids from the roots and processed products of Aconitum pendulum.Methods The chemical constituents were isolated and purified using silica gel column chromatography.Their structures were determined on the basis of NMR and mass spectra.ResultsTwelve compounds were isolated and identified as deoxyaconitine(1),3-acetylaconitine(2),aconitine(3),15?-OH-neoline(4),8-acetyl-15-hydroxyneoline(5),neoline(6),14-benzoyl-8-O-methylaconine(7),benzoylaconine(8),polyschistine D(9),benzoyldeoxyaconine(10),polyschistine A(11),and aconine(12).Conclusion Diterpene alkaloids are the main chemical constituents of A.pendulum and compounds 4—8 are found in this plant for the first time.Compared to raw materials,some boiled processed products change into new components:polyschistine D(9),benzoyldeoxyaconine(10),polyschistine A(11),and aconine(12).Identification of these components provides basis for the processing principles.

Objective:There is a large of population of macrophages resident in the testicular interstitial tissue under normal conditions and they are increased during inflammation.The mechanisms involved are unclear.This study focused on the expression of monocyte chenoattractant protein-1 (MCP-1) in the mouse testis before and after an intraperitoneal injection of LPS.Methods:The expression of MCP-1 in testis was detected by using reverse transcription-polymerase chain reaction and Western blot,the immunofluorescent technique was used to detect the localization of MCP-1 protein in testis.Results:In the normal testis,the expression of MCP-1 mRNA and protein was detectable by RT-PCR and immunofluorescent technique,respectively.The level of testicular MCP-1 mRNA increased dramatically at 3-24 h after LPS treatment,the level of MCP-1 protein increased at 12 h after LPS treatment.The MCP-1 was localized in the testicular interstitial tissue.Conclusion:MCP-1 may play a role in maintaining the resident macrophage population in normal testis and regulating monocyte and macrophage influx in inflammatory testis.

OBJECTIVETo study the processing principles of different processed products of Aconitum pendulum.

METHODUsing high performance liquid chromatography and acute toxicity test to compare the changes in chemical composition and toxicity of the roots and processed products of A. pendulum.

RESULTThe main toxic components of the roots of A. pendulum were aconitine, deoxyaconitine and 3-acetylaconitine. The contents of these three alkaloids were significantly reduced in processed products, while benzoylaconitine significantly increased. In addition, processed products emerged aconine, polyschistine-D, beyzoyldeoxyaconine, 16-epi-pyroaconitine and 16-epi-pyrodeoxyaconitine. From the structural analysis, these new emerged compounds transformed from the aconitine, deoxyaconitine and 3-acetylaconitine.

CONCLUSIONDifferent processing methods can reduce the toxicity of the roots of A. pendulum. Processing principle is ester hydrolysis and high-temperature pyrolysis.

Objective To report the diagnosis of a canine distemper virus outbreak among a colony of cynomolgus monkeys at an experimental monkey farm in 2019. MethodsA total of 46 samples were collected from 21 diseased cynomolgus monkeys (exhibiting symptoms such as facial rash, skin scurf, runny nose, and diarrhea) and from one deceased monkey at an experimental monkey breeding farm in South China in late 2019, including serum, skin rash swabs, and anticoagulated whole blood, liver, lung, and skin tissues were submitted for testing. All submitted samples were tested for canine distemper virus gene fragments using real-time quantitative PCR, while immunohistochemical staining was performed to detect canine distemper virus nucleoprotein in lung tissues. The skin tissue of the deceased monkey was ground and sieved. The filtrate was inoculated into a monolayer MDCK cell line for virus isolation. Then, whole-genome sequencing was performed to identify the isolated virus. The Clustal Omega tool was used to align and analyze the homology of different Asian canine distemper virus isolates. A phylogenetic tree was constructed, followed by genetic evolutionary analysis. ResultsClinical retrospective analysis revealed that the diseased cynomolgus monkeys exhibited symptoms similar to those observed in cynomolgus monkeys infected with measles virus. Necropsy findings showed red lesions in the lungs and significant hemorrhage in the colonic mucosa. Real-time quantitative PCR detected canine distemper virus nucleic acid in the serum, skin rash swabs of the infected monkeys, and various tissue samples of the deceased monkey, all of which tested positive. Calculation based on the standard curve formula indicated the viral load was highest in the skin tissue. Immunohistochemical staining of the deceased monkey's lung tissue demonstrated aggregation of CDV nucleoprotein in alveolar epithelial cells, bronchi, and bronchioles. A CDV strain was isolated from the skin tissue of the deceased monkey. Phylogenetic analysis indicated that this strain shares the closest relationship (98.86%) with the Asian-1 type canine distemper virus strain CDV/dog/HCM/33/140816, previously identified in dogs in Vietnam. ConclusionBased on comprehensive analysis of clinical symptoms, nucleic acid detection, viral protein immunohistochemistry, and whole-genome sequencing results, the diagnosis confirms that the cynomolgus monkeys in this facility are infected with canine distemper virus. It is recommended to include canine distemper virus as a routine surveillance target in captive monkey populations. Additionally, this study provides a foundation for further research on the molecular biological characteristics of canine distemper virus.
