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.

In control group, the correlation coefficients of urinary Cu to Zn, Se, and Ba, those of Zn to Se and Ba, and those of Cr to Mn and Ba were all bigger than 0.516(all P ＜ 0.05), those of hair Al to Mn,Fe, Cu, As, and Se, and those of hair Se to Fe, Cu, and As, those of hair Fe to Mn, Cu, and As, those of hair Cu to Zn and As, and that between Zn and As were bigger than 0.739(all P ＜ 0.05). The correlation coefficient of urinary F to Se in patient group(0.762) was significantly different from that in control group( - 0.469, u = 2.079,P ＜ 0.05). Conclusions The burden of F and Al of osteomalacia malformation children in endemic fluorosis area of Shuicheng county is too high. The contents of multi-elements in urine and hairs and their correlation are coincident with high levels of Al and F and they cause network increase of multi-element content changes and their correlation. According to bone X-ray features combining with the living environment, the diagnosis of endemic Al-F fluorosis can be made. The biological significance of reducing urinary and hair Se levels and the correlations of F and Al need to be further studied.

To develop an analytic method for qualitative and quantitative analysis of dodecatetraenamides A, B in 42 samples of two official species of Asari Radix et Rhizoma( ARR) (37 samples of Asarum heterotropoides var. mandshuricum with different collection time and 5 samples of Asarum sieboldiivar. seoulense). The HPLC-IT-TOF-MS/MS methods for the qualitative and UPLC-PDA methods for the quantitative analysis were established. Dodecatetraenamides A, B were identified by comparing the retention time, UV absorption spectrum and quasi-molecular ion peak [ M + H]+ with the reference compound using HPLC-IT-TOF-MS/MS. The content of dodecatetraenamides A and B in ARR were determined by UPLC-PDA. The separation was successfully carried out on a ACQUITY UPLC BEH C18 (2.1 mm x 100 mm, 1.7 µm) column eluted with mobile phases of water (A) and acetonitrile (B) in gradient program (0-3 min, 35% B; 3-5 min, 35%-36% B; 5-6 min, 36%-43% B; 6 min-11 min 43% B; 11-12 min, 43%-100% B). The column temperature was 45 °C, and the detection wavelength was set at 254 nm. The flow rate was 0.6 mL · min(-1). On one level mass spectrometry scanning, the results showed that the quasi-molecular ion [M + H] + of both dodecatetraenamides A and B were m/z 248.20. The quantitative method with UPLC-PDA has made the baseline separation of the constituents, which were reported as mixtures in the most literatures. The average recovery of dodecatetraenamides A and B were 97.90% and 99.86%, the relative standard deviation were 0.4% and 1.1%, respectively. The contents of dodecatetraenamides A, B in all ARR samples was in the range of 0.11-3.89 and 0.24-6.65 mg · g(-1). Their contents reduced with the extension of storage time. Compared with the samples of 2013, the average content of the two constituents in the samples collected in year 2002-2003 reduced 34% and 36%, respectively (P < 0.05). Compared the A. sieboldii var. seoulense and A. heterotropoides var. mandshuricum with the same collective time and production area, the average contents of the two constituents in latter were up to (1.59 ± 0.75) mg · g(-1) and (2.90 ± 1.17) mg · g(-1), respectively, significantly higher than that in A. sieboldii var. seoulense (dodecatetraenamide A were (0.78 ± 0.52) mg · g(-1), dodecatetraenamide B were (1.69 ± 0.83) mg · g(-1)) (P < 0.05). The content of the dodecatetraenamide A in overground part was in the range of 0.11-0.33 mg · g(-1), dodecatetraenamide B was 0. 24-0.60 mg · g(-1), which were much lower than that of the underground part of ARR (dodecatetraenamide A was in the range of 0.73-3.89 mg · g(-1), dodecatetraenamide B was 2.11-6.24 mg · g(-1)). The method was certified to be simple, accurate and reliable and could be used for qualitative and quantitative analysis of dodecatetraenamide A and B in different species of ARR, also can be used for the comprehensive quality control of traditional Chinese medicine, Asari Radix et Rhizoma.

As one of the major sources of infection, viruses could infect all organisms including bacteria, plants, animals, and humans. Infectious diseases caused by viruses pose a great threat and damage to human health and economic activities all over the world. Adaptor-associated protein kinase 1 (AAK1) is a member of the Ark1/Prk1 family of serine/threonine kinases and a specific key kinase regulating the phosphorylation of AP-2 protein μ2 subunit T156. In the past, AAK1 has been regarded as a feasible biological target for the treatment of nerve pain. Recently, scientists have found that inhibiting AAK1 can regulate endocytosis and inhibit virus invasion into cells. Therefore, AAK1 could be the potential target of anti-virus therapy. This paper reviews the research progress of small molecule AAK1 inhibitors in the field of antiviral, analyzes the future research directions and challenges, and provides new ideas for the development of antiviral drugs targeting AAK1.

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 6-week study was conducted to evaluate the effects of seven different levels of dietary chromium (Cr) (0, 75, 150, 300, 450, 600, and 1 200 ppb Cr) in the form of Cr nanoparticle (CrNano) on growth, body composition, serum hormones and tissue Cr in Sprague-Dawley (SD) rats. Seventy male SD rats (average initial body weight of (83.2+/-4.4) g) were randomly assigned to seven dietary treatments (n=10). At the end of the trial, body composition was assessed via dual energy X-ray absorptiometry (DEXA). All rats were then sacrificed to collect samples of blood, organs and tissues for determination of serum hormones and tissue Cr contents. The results indicated that lean body mass was significantly increased (P<0.05) due to the addition of 300 and 450 ppb Cr from CrNano. Supplementation of 150, 300, 450, and 600 ppb Cr decreased (P<0.05) percent body fat significantly. Average daily gain was increased (P<0.05) by addition of 75, 150, and 300 ppb Cr and feed efficiency was increased (P<0.05) by supplementation of 75, 300, and 450 ppb Cr. Addition of 300 and 450 ppb Cr decreased (P<0.05) the insulin level in serum greatly. Cr contents in liver and kidney were greatly increased (P<0.05) by the addition of Cr as CrNano in the dosage of from 150 ppb to 1 200 ppb. In addition, Supplementation of 300, 450, and 600 ppb Cr significantly increased (P<0.05) Cr content in the hind leg muscle. These results suggest that supplemental CrNano has beneficial effects on growth performance and body composition, and increases tissue Cr concentration in selected muscles.

OBJECTIVETo investigate the effects of electromagnetic radiation on the physiological indices and immune function of operators.

METHODSThe general conditions and electromagnetic radiation awareness rate of 205 operators under electromagnetic radiation were evaluated using a self-designed questionnaire. Physical examination, electrocardiography, and routine urine test were performed in these operators. Peripheral blood was collected from the operators under electromagnetic radiation for blood cell counting and biochemical testing, and their peripheral blood lymphocytes were cultured for determination of chromosomal aberrant frequency and micronucleus frequency. The data from these operators (exposure group) were compared with those of 95 ordinary individuals (control group).

RESULTSThe chief complaint of giddiness, tiredness, dizziness, and amnesia showed significant differences between the exposure group and control group (P < 0.01), and the difference in headache became larger with an increase in working years. The awareness rate of electromagnetic radiation damage was significantly higher in the exposure group than in the control group. The difference in bradycardia was significant between the two groups (P <0.01), and the incidence was higher with longer working years. Significant differences between the two groups were also found in the numbers of individuals with elevated alanine aminotransferase, total bilirubin, and direct bilirubin (P < 0.01), populations with increased lymphocyte ratio and decreased neutrophil ratio (P < 0.01), populations with positive occult blood, urobilinogen, and bilirubin tests, and the number of individuals with increased micronucleus frequency of cultured peripheral blood lymphocytes (P < 0.01). In addition, the exposure group had significantly increased complement C3 and C4 (P < 0.01), significantly increased IgG (P < 0.05), and significantly decreased IgM (P < 0.01), as compared with the control group.

CONCLUSIONElectromagnetic radiation may lead to the changes in physiological indices, genetic effects, and immune function and affect the health and immune function in operators. The adverse effects are increased as the working years increase. So it is important to strengthen occupational protection of operators under electromagnetic radiation.
