The clinical thinking modes of "integrative disease and Syndrome" and "integrative macroscopical Syndrome-differentiation and microscopical Syndrome-differentiation" formed in the past half century were merely the primary train of thought and methodology of integrative traditional Chinese and Western medicine. In order to develop them to a higher level, stress should be put on the unity and holism of disordered organism and unity of function, structure and metabolism. It has long been ignored that a parallel and correlated relationship exists between the TCM Syndrome and pathological process of Western medicine, which is a common, set-formed and regular pathophysiological changes with certain development phase, presented in various diseases. Both have common features as that the same pathological process can be seen in different diseases and several pathological progresses can present in one disease, the same Syndrome also can be seen in different diseases and several Syndromes can present in a disease. Moreover, they have the compatible connotation and denotation. The author deduced that pathophysiological basis of main Syndrome is indeed the basic pathological process. Essence of Syndrome is the related pathological processes including abnormal changes in function, metabolism and morphological structure.

To make a preliminary study on the mechanism of Coptidis Rhizoma(CR) and Rehmanniae Radix(RR) before and after the combined administration in treating type II diabetes mellitus. The type I diabetes animal model in rats was established by fat emulsion and intraperitoneal injection with streptozotocin, in order to compare the hpyerglycemic and hypolipidemic effects of CR, RR and their combined administration of different ratio. The urinary metabolic profiling in rats of Coptidis Rhizoma and Rehmanniae Radix before and after the combined administration was analyzed by using the gas chromatography-mass spectrometry. The differences among groups in metabolome were analyzed by the principal component analysis (PCA). The biochemical index results indicated that both CR and RR before and after the combined administration could lower high blood glucose, hypertriglyceride and high cholesterol. According to the analytical results of PCA of the rats' urine samples, the CR group was the most close to the normal group, with no significant difference in CR and RR group of different combination ratios. Twelve differentiated metabolites were identified to be related to type II diabetes. Compared with the normal group, the CR-treated group showed significant increase in seven differentiated metabolites. Among CR and RR drugs with different combination ratios, CR played a major role and thus acted as the monarch drug. Whereas RR served as the ministerial drug and assisted CR to show the efficacy. This study laid a foundation for the explanation of the combination mechanism of traditional Chinese medicines.

Fall down is related to stability of persons,especially in the aged.Poor stability usually results in fall down.Compared with the concept of static stability,dynamic stability theory emphasizes the velocity-position of center of mass(CoM)to predict feasible move-ments rather than CoM position only. Dynamic stability can help to estimate the risk of fall, and guide the exercise about fall prevention from improvements of adaption to regain balance.The training program still needs more studies.

This study was purposed to evaluate the sensitivity and specificity of G/(1, 3-β-D glucan)/GM (galactomannan) combined detection for early diagnosis of invasive fungal disease (IFD), determine the GM positive cut-off value, and investigate the change of diagnostic level before and after G/GM test and the relation of GM value with therapeutic effect. The ELISA with double antibody sandwich was used to detect the serum levels of G and G/M. The results showed that according to determined GM positive cut-off value, the sensitivity, specificity, positive and negative predictive value of G/GM combined detection were 100%, 65.7%, 67.6% and 100%, respectively. The case number of the clinical diagnosis of IFD increased from 1 to 24 cases, the diagnosis of 12 non-infective patients was changed as suspected IFD with the help of G/GM combined detection; the GM cut-off value decreased in patients whose GM cut-off value was higher before therapy and antifungal therapy was effective, while the GM cut-off value increased in patients no-responded to therapy. It is concluded that G/GM combined detection can increased the sensitivity of the diagnosis and reduce false negative rate in the early diagnosis of IFD. The dynamically monitoring G/GM cut-off value can be used as evaluation indicator of therapeutic efficacy.

AIMTo observe the change of potassium current on cultured neurons differentiated from hippocampus neural stem cells of the newborn rat.

METHODSNeural stem cells from newborn rat hippocampus were cultured in vitro and passaged continuously. Differentiation of the cell was induced by serum and removing mitogens. After differentiation cells were plated on plastic dishes and cultured for 1 d, 7 d, 14 d and 21 d. Whole-cell voltage patch clamp recording was used respectively to detect voltage-dependent K+ current.

RESULTSAfter 1 d culture, no current was detected, and on the 7th d, 14th d, 21st d after differentiation, the amplitude of K+ currents was (18.077 +/- 2.789)pA/pF, (13.099 +/- 2.742)pA/pF, (34.045 +/- 8.067)pA/pF at +50 mV. The recorded K+ current included two components that could be blocked by TEA and 4-AP separately, assumed the slowly inactivating delayed rectifier K+ current (IK) and the fast inactivating transient outward K+ current (IA).

CONCLUSIONThe function of potassium channels on the hippocampus neural stem cells of the newborn rat approaches mature gradually when the time of differentiation becomes longer in vitro.

This study was aimed to investigate the function defect of partial homing receptor on cord blood hematopoietic stem cells (CBHSC) and explore efficacy and feasibility of intervention in vitro. The expression and activity of active groups in P, E-selectin ligands on CD34+ cells from cord blood, bone marrow and peripheral blood were detected by flow cytometry; meanwhile the expression of active groups in selectin ligands on CD34+ cells treated by fucosyl transferase in vitro was determined by flow cytometry. The results indicated that the expression levels of CD26 on the surface of stem/progenitor cells (CD34+) from cord blood, bone marrow and peripheral blood were (7.62+/-0.63)%, (6.35+/-0.89)% and (6.18+/-0.91)% (p>0.05) respectively. And the activities of CD26 of the three sources of stem cells were 67.15 U/1000 cells (1 U=1 pmol/min), 26.85 U/1000 cells and 20.95 U/1000 cells respectively, in which the activity of CD26 on surface of CD34+ from cord blood was significantly higher than that from other both sources (p<0.01). The expression levels of P-selectin ligand on the stem/progenitor cells three kinds were (83.46+/-6.33)%, (15.65+/-0.89)% and (80.17+/-6.85)%, and the expression levels of E-selectin ligand on stem/progenitor cells of three kinds were (25.31+/-1.03)%, (26.34+/-0.89)% and (29.79+/-1.78)% respectively. The expression of E-selectin ligand on the surface of cord blood stem/progenitor cell CD34+ increased from (25.31+/-1.03)% to (63.23+/-1.08)% after glycosylation engineering. It is concluded that there is no significant difference of the expression of CD26 between the three sources of stem/progenitor cells, but the activity of CD26 in cord blood was obviously higher than that in bone marrow and peripheral blood. The expression of P-selectin ligand on bone marrow stem/progenitor cell was lower than that on stem cells of cord blood and peripheral blood. Glycosylation engineering can promote and elevate the expression of E-selectin ligand on the surface of CD34+ cells from cord blood.

A female infant, aged 43 days, had shortness of breath, cyanosis, groan, and dyspnea since birth. Physical examination showed cyanosis of lips and three-concave sign, and multiple lung imaging examinations showed diffuse ground-glass opacities in both lungs. The girl was given anti-infective therapy and continuous mechanical ventilation but there were no significant improvements in symptoms. Gene testing confirmed a compound heterozygous mutation, c.1890C>A(p.Tyr630Ter)+c.3208G>A(p.Ala1070Thr), in the ABCA3 gene, with the former from her father and the latter from her mother. Pathological examination of the lungs indicated pulmonary interstitial disease. The girl was diagnosed with infantile diffuse pulmonary interstitial disease caused by mutations in the ABCA3 gene. When full-term neonates experience shortness of breath and dyspnea after birth, pulmonary imaging suggests diffuse ground-glass changes, and conventional treatment is not effective (ventilator-dependent), congenital pulmonary surfactant metabolism defects needs to be considered. Gene testing, which can provide a basis for early intervention, prognostic evaluation, and genetic counseling, should be performed as early as possible.

OBJECTIVES: To study the metabolic mechanism of neonatal sepsis at different stages by analyzing the metabolic pathways involving the serum metabolites with significant differences in neonates with sepsis at different time points after admission. METHODS: A total of 20 neonates with sepsis who were hospitalized in the Department of Neonatology, Hunan Provincial People's Hospital, from January 1, 2019 to January 1, 2020 were enrolled as the sepsis group. Venous blood samples were collected on days 1, 4, and 7 after admission. Ten healthy neonates who underwent physical examination during the same period were enrolled as the control group. Ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry was used for the metabonomic analysis of serum samples to investigate the change in metabolomics in neonates with sepsis at different time points. RESULTS: On day 1 after admission, the differentially expressed serum metabolites between the sepsis and control groups were mainly involved in the biosynthesis of terpenoid skeleton. For the sepsis group, the differentially expressed serum metabolites between days 1 and 4 after admission were mainly involved in pyruvate metabolism, and those between days 4 and 7 after admission were mainly involved in the metabolism of cysteine and methionine. The differentially expressed serum metabolites between days 1 and 7 after admission were mainly involved in ascorbic acid metabolism. CONCLUSIONS The metabolic mechanism of serum metabolites varies at different stages in neonates with sepsis and is mainly associated with terpenoid skeleton biosynthesis, pyruvate metabolism, cysteine/methionine metabolism, and ascorbic acid metabolism.
