Chinese Journal of Schistosomiasis Control 2016;28(3):264-268
Objective To evaluate the effects of 3 kinds of ELISA reagents on the detection of human paragonimiasis. Meth?ods A total of 45 serum samples from patients with paragonimiasis,218 serum samples from patients with other parasitic dis?eases as well as 80 serum samples from healthy people were detected by GD?ELISA(IgG antigen ELISA detection reagent),ES?ELISA(using excretory/secretory(ES)products of Paragonimus westermani),and sAg?ELISA(using semi?purified antigen (sAg)of P. westermani),respectively. The effects of the 3 reagents were evaluated and compared. Results The sensitivities of GD?ELISA,ES?ELISA,and sAg?ELISA were 95.6%(95%CI:89.6%~100.0%),93.3%(95%CI:86.0%~100.0%)and 86.7%(95%CI:76.8%~96.6%),respectively;the specificities of the above three reagents were 88.6%(95%CI:85.0%~92.2%),88.9%(95%CI:85.3%~92.5%)and 99.0%(95%CI:97.9%~100.0%),respectively,and the Youden indexes of them were 0.84,0.82 and 0.86,respectively. Conclusion sAg?ELISA is more suitable than GD?ELISA and ES?ELISA for clin?ical sample tests in paragonimiasis endemic areas in China.
2.Origin and development of microcosmic syndrome differentiation
Journal of Integrative Medicine 2005;3(5):342-6
The suggestion of microcosmic syndrome differentiation is to meet the needs of clinical diagnosis and treatment of traditional Chinese medicine (TCM), the needs of evidence based medicine and the needs of the development of syndrome differentiation in TCM. The possibility of microcosmic syndrome differentiation might be the development of integration of traditional Chinese and Western medicine as well as modern science and technology. Microcosmic syndrome differentiation has its superiority and limitation. There are some problems in developing microcosmic syndrome differentiation, such as lack of standard for syndrome differentiation, contradiction between single microcosmic index and the entirety, non-specificity of the relationship between microcosmic indexes and syndromes, and the influence of disease on microcosmic syndrome differentiation, discrepancy between the essence study of TCM syndromes and the clinical practice. It is suggested that the concept of TCM syndrome is a certain pathological process during the onset and development of disease, composed of some subjective and objective indexes. The objective indexes include the macrocosmic and the microcosmic indexes, the entirety and the part.

Hologram is a theory to study the properties and laws of the world under a holographic interaction.Traditional Chinese Medicine(TCM) shares many common fi elds with hologram theory.Although some originally diagnostic folk methods such as Zhejiang.sixian pulse theory,Kunlun?tianyuan pulse theory have been rarely known and have not been widely recognized in modern time,the diagnostic methods of Jiugong pulse and hologram pulse based on the two pulses theories have shown its uniqueness and effectiveness through hundreds of years of clinic practices.Based on holographic principles and holism,a physician can make diagnoses noninvasive,simple and rapid,which is benefi t for inheritance and development of TCM pulse methods.

Babesia parasites are obligate intracellular apicomplexan protozoa and important pathogens causing babesiosis of humans and animals. They have conserved subcellular structures and invasion mechanism. Rhoptry⁃associated proteins,which are released into the host cell,are considered to be the key molecules of invasion and replication of parasites in the host cell and are immunosuppressive factors of the host cell mediated immunity in the stage of parasitophorous vacuole(PV)formation. The knowledge about rhoptry⁃associated proteins has made a great progress with the development of genomics and proteomics,so we review the research progress in rhoptry⁃associated proteins of different Babesia including Babesia bovis,B. ovine,B. gibsoni,B. bigemina and B. orientalis,etc.

Schistosomiasis Control and Elimination(GB 15976-2015)and Diagnostic Criteria for Schistosomiasis(WS 261-2006)are the only two national health criteria related to schistosomiasis control program implemented in P. R. China. The roles of criteria to guide and accelerate the transition from schistosomiasis control to elimination are concluded ,based on this system?atic review how the criteria led the implementation of the medium?and long?term national plan and provided the guidance when drafting the thirteen?five years national plan for schistosomiasis,and the suggestion to draft more criteria related to schistosomia?sis elimination program and strengthening the implementation of current criteria,so as to precisely guide the schistosomiasis elimination program in P. R. China.

Some researchers focus on research of the nature of syndromes. The methods of combining traditional Chinese medicine syndrome and diseases and the correspondence between formulas and syndromes may be used in research of the nature of syndromes. According to combined theories of zang-organ state and seven emotions in traditional Chinese medicine with stress theory in modern medicine, the authors applied the methods of chronic immobilization stress to induce liver depression and spleen deficiency syndrome in rats based on the thinking of relativity on formula and syndrome. The research showed that the central neurobiology mechanism of liver depression and spleen deficiency syndrome closely correlates to the hypothalamic-pituitary-adrenal axis, brain-gut axis, myriad central neurotrophic factors, neurotransmitters, neuropeptides and hormones and their receptors, involving in many encephalic regions such as the hypothalamus, hippocampus, cortex, amygdale, etc. The authors will combine their previous work with multi-disciplinary research, such as genomics, proteomics, metabolomics and bioinformatics in future studies, to reveal the scientific connotations of liver depression and spleen deficiency syndrome.

OBJECTIVE: To determine the changes of the plasma metabolic phenotype in rats with chronic restraint stress (rats with syndrome of liver qi stagnation and spleen deficiency), so as to reveal the biological features of the syndrome of liver qi stagnation and spleen deficiency, and to examine potential application of metabonomic analysis in studies of syndromes in traditional Chinese medicine. METHODS: Twenty-four male Sprague-Dawley rats were randomly divided into four groups: group A, 7 d normal control group; group B, 21 d normal control group; group C, 7 d stress group; and group D, 21 d stress group, with 6 rats in each group. Chronic restraint was used to induce stress in rats. Blood was collected from the cardio-ventricle under anesthesia on the 8th (groups A and C) or 22nd day (groups B and D) and detected by using the Fourier variable superconducting nuclear magnetic resonance (NMR) spectrometer (Varian UnityInova 600 M). Free induction decay signals were transferred into one-dimensional NMR spectrogram via 32 k Fourier transformation. Segmental integral calculus (0.04 ppm per segment) was performed from 4.5-0.5 ppm (Carr-Purcell-Meiboom-Gill, CPMG) or 6.0-0 ppm (longitudinal eddy-delay, LED) as defaulted 1H spectra values by using the VNMR software. Data were saved as text or excel files after normalization and then used for pattern recognition analyses. All the data were analyzed by principal component analysis (PCA) using the SIMCA-P 10.0 software (Umetrics AB, Umea, Sweden). RESULTS: The PCA analysis of rat plasma (1)H NMR spectra revealed different metabolic spectra between stress and control groups, which were consistent with alterations of in vivo metabolisms in rats under stress stimuli. Compared with the normal control group, rats with repeated stress displayed significant changes in spectral peak shapes of acetate, lactate, tyrosine, low-density lipoprotein, and unknown compounds (3.44 ppm). These altered metabolites can be used as biomarkers of syndrome of liver qi stagnation and spleen deficiency for further studies. CONCLUSION: The (1)H NMR spectra of metabolites in the rat blood are differentially changed after chronic stress. Specific, characteristic metabolic products can be identified by analyses of metabonomics, which lead to interpretation of biological feature of Chinese medicine syndromes. Therefore, metabonomic analysis is an approach with good development prospects to studies of TCM syndromes.
