In this paper, based on the special influence of supramolecular chemistry on the basic theory of Chinese medicines ( CM) , the authors further analyzed the history of meridian tropism and natural origins of CM organisms and explained CM ingredients and the universal regularity of the automatic action of the supramolecular "imprinting templates" hole channel structure. After entering human bodies, CMs, as the aggregation of supramolecular "imprinting templates" , automatically seek supramolecular subjects that are matched with their "imprinting templates" in human meridians and organs for the purpose of self-recognition, self-organization, self-assembly and self-replication, so as to generate specific efficacy in meridians and organs, which is reflected as the meridian tropism phenomena at macro level. This regularity can be studied by in vitro and in vivo experimental studies. In vitro methods are mostly supra molecular structure analysis and kinetic and thermodynamic parameter calculation; Whereas in vivo methods are dominated by the analysis on object component distribution, chromatopharmacodynamic parameters and network chromatopharmacodynamic parameters; Particularly, the acupoint-medicine method can simplify to study the supramolecular subject-object relations. Consequently, CM's'meridian tropism reveals the universal regularity for interactions of macromolecular and micromolecular "imprinting templates" of subjects and objects in natural organisms. As the first barrier for the material base of the CM theory and breakthrough in the modernization of the basic CM theory, meridian tropism plays an important role in studies on basic theories of the basic CM theory.

The paper aimed to elucidate the specific impact of supramolecular chemistry on the Chinese medicine theories (CMT) in their modernization, after had summarized up the research status of supramolecular chemistry and analyzed the possible supramolecular forms of Chinese medicine (CM), as well as considered the problems in modernization of CM theories. On comparison of the classical chemistry that delt with chemical bonds among atoms, the supramolecular chemistry was rather concerned with varietes of weak noncovalent bonds intermolecules, and reflected the macro-apparent chemical properties of each molecules, and was the most appropriate chemical theories to explain the CMT and microcosmic materials. The molecules in the human body and Chinese material medica (CMM) formed supramolecules by way of self-assembly, self-organization, self-recognition and self-replication, with themselves or with complexation, composition, chelation, inclusion, neutralization etc. Meridian and Zang-fu viscera in CMT might be a space channel structure continuously consisted of unique molecules cavity that was imprinted with the supramolecularly template inside and outside of cells, through which the molecules in CMM interacted with the meridian and Zang-fu viscera. When small molecules in human body imprinted with macromolecules in meridian and Zang-fu viscera, in other words, they migrated along within imprinting channels of meridian and Zang-fu viscera on behavior of "Qi chromatography" impulsed by the heart beat, finally showed up on macroscopic the anisotropy of tissue and organ, as described namely as visceral manifestation in Chinese medical science. When small molecules in CMM interacted with imprinting channel on meridian and Zang-fu viscera, the natural properties and efficacy regularities of CMM was reflected on macroscopic. Therefore, the special representation forms of basic CMT is based on the macroscopic expression of "Qi chromatography" abided by imprinting effect regularities, and on whether the imprinted template of small molecules matched with cavity template of macromolecules in meridian and Zang-fu viscera, only is the adequate representation of supramolecular chemistry for them. The CMM materials is the mixture including single molecules and supramolecules. The compatibility for CM prescriptions can significantly change the function rules. Therefore in the study of basic CMT, we should pay special attention to the laws of supramolecular chemistry. It is the most essential differences of the CMT from the modern medicine which established by the laws of single molecular theories.

OBJECTIVETo investigate the changes in plasma levels of vascular endothelial growth factor (VEGF) and stromal cell-derived factor-1 (SDF-1) and in peripheral CD34(+) cells in patients with acute myocardial infarction (AMI), and explore their role in AMI.

METHODSEnzyme-linked immunoassay (ELISA) was employed for measuring the levels of VEGF and SDF-1 in AMI patients on days 1, 3, 7, 10, and 14 of onset and in normal control subjects. The absolute counts of CD34(+) in the peripheral blood were measured on days 1, 7, and 14 by flow cytometry in AMI patients, with their myocardial enzyme and troponin I detected and electrocardiography (ECG) and echocardiography (UCG) recorded.

RESULTSPeripheral CD34(+) cells obviously increased on day 7 after AMI onset (2.35-/+0.72/microl vs 1.48-/+0.49/micro, P<0.05). VEGF levels were significantly higher in AMI patients than in the control subjects, reaching the peak level and on day 14 (197.56-/+39.87 vs 53.79-/+18.12 pg/ml, P<0.01). SDF-1 level obviously decreased on day 1 after AMI onset (1683.12-/+224.79 vs 2178.67-/+265.34 pg/ml, P<0.01), followed by gradually increased to the control level. Obvious correlation was noted between the level of VEGF on day 7 and the peak level of peripheral CD34(+) cells, and the peak plasma VEGF level was obviously associated with the peak serum CK-MB and troponin I levels.

CONCLUSIONThe stem cells are mobilized into the peripheral blood in the event of AMI. Obviously increased VEGF level following AMI may persist for at least 2 weeks, whereas SDF-1 level undergoes temporary decrement after AMI. The dynamic changes of VEGF and SDF-1 can be related to the mobilization and homing of the stem cells to the injured myocardium.

OBJECTIVETo investigate the effects of hydroxycamptothecin (HCPT) on proliferation and apoptosis of rat hepatic stellate cells (HSC).

METHODSRat HSC line (HSC-T6) and rat hepatocyte line (BRL-3A) were treated with different concentrations of HCPT (0, 0.008, 0.016, 0.031, 0.125, 0.25, 0.5, 1, 2, 4, 8, 16, 32 mg/L respectively) for 24 h. Cell proliferation was assessed by MTT colorimetric assay, apoptosis was detected with PI staging followed by flow cytometry, and by DNA ladder assay. The morphological change of apoptosis was observed under transmission electron microscopy (TEM).

RESULTSMTT assay indicated that HCPT significantly inhibited the proliferation of HSC-T6 and BRL-3A in a dose-dependent manner. 24 h after the treatment with different concentrations of HCPT (0.25, 0.5, 1 mg/L), the apoptosis rate (13.46%+/-2.42%, 26.25%+/-5.65%, 47.05%+/-8.76%, respectively) in HSC-T6 was significantly higher than that in control cells (4.89%+/-1.80%, F = 34.24, P less than 0.01). 24 h after 0.5 mg/L HCPT treatment, cell shrinkage, nucleoli disappearance, chromatin condensation were found under TEM, and DNA ladder was demonstrated by agarose gel electrophoresis.

CONCLUSIONHCPT could significantly inhibit proliferation and induce apoptosis of HSC-T6 in a dose-dependent manner.

The paper, based on the previous publication as special impact of Chinese medicine theories on supramolcular chemistry, aims to analyze the natural origination for the Chinese medicine and to explain the special impact of "Qi chromatography" reaction on "imprinting templates" in supramolcular host of human being with Chinese medicine, in order to reveal the CM's properties of "medical element" with "imprinting templates" autonomisation generally took place in natural supramolecules, and also to discover that the CM's pharmacology are satisfied with its own approaches different form western pharmacology. It was decided, for CM's pharmacology guided by CM's theories, to "Qi chromatography" relations between the CM's ingredient groups and the meridian zang-fu viscera. The supramolcular chemistry played an all-through role in procession of making macro-regularities and special presentation on behavior of "Qi chromatography" impulse owning to the matching action of all kinds of ingredients on the meridian zang-fu viscera with similar "imprinting templates". The CM's pharmacology were guided by CM's theories, owing to its interpretation of supramolecular chemistry. The pharmacology was achieved to construct up completely on base of classical chemical single molecular bonds whereas the CM's pharmacology be configured to big building by way of "imprinting templates" as multi-weak bonds among "supramolecular society". CM's pharmacology was supramolcular pharmacology dealt with "molecular society" on the base of western pharmacology, and employed to double research approaches both math-physical quantitative representation on macroscope and qualitative analyses in microscope.

OBJECTIVETo evaluate the effect of chronic virus infection on laboratory tests results in patients with osteoarticular tuberculosis.

METHODSA total of 121 patients with osteoarticular tuberculosis, who were hospitalized in Shenzhen Third People's Hospital during June 2008 to June 2012, were recruited for analysis. Clinical laboratory tests results were collected for comparison between patients with or without chronic co-infection with virus.

RESULTSAmong the 121 patients, thirty patients were co-infected with hepatitis B virus (HBV), two were with Human immunodeficiency virus (HIV), and one was co-infected with HBV, HIV and hepatitis C virus (HCV). Compared to patients with osteoarticular tuberculosis without HBV/HCV/HIV infection, patients with chronic HBV/HCV/HIV virus infection had similar positive rate of laboratory tests including tissue smear acid-fast bacilli (AFB) staining, tissue Mycobacterium tuberculosis (Mtb) culture, tissue Mtb DNA detection, serological test of antibodies against Mtb, and Mtb. antigen-specific interferon-gamma release assay. Similar results were also found for erythrocyte sedimentation rate, C-reative protein level and liver function including Alanine aminotransferase and Aspartate Aminotransferase.

CONCLUSIONChronic infection with HBV/HCV in patients with have no obvious effect on clinical laboratory tests related to tuberculosis.

Objective To investigate the frequency of CD4~+CD25~+FoxP3~+regulatory T cells (Treg)and the expression of the functional protein,FoxP3,in patients with active tuberculosis and the relationship between Treg and the pathogenesis of tuberculosis.Methods Forty-five patients with active tuberculosis(including 25 cases of pulmonary tuberculosis and 20 tuberculous lymphadenitis), 20 healthy controls,20 recovered tuberculosis patients and 6 patients with reactive hyperplasia in cer- vical lymph node were enrolled.The frequency of CD4~+ CD25~+ FoxP3~+ Treg in the peripheral blood was measured by flow cytometry.FoxP3 mRNA expression was determined by real-time reverse transcriptase-polymerase chain reaction(RT-PCR)and the expression of FoxP3 protein in lymphoid tissues was measured by immunohistochemistry.Results The frequency of natural Treg in the peripheral blood from the patients with active tuberculosis was 2.91%?0.23%,which was signifi- cantly higher than that of healthy control group(1.22%?0.18%)and recovered tuberculosis patients(1.50%?0.17%,P

OBJECTIVE: To evaluate the clinical efficacy and toxicity of priming induction regimen of CAG for newly diagnosed acute myeloid leukemia (AML) in elderly patients. METHODS: Seventy-five patients with newly diagnosed AML were divided into 2 groups: 34 were treated with priming induction regimen CAG and the other 41 were treated with 2 classic routine chemotherapy regimens including pirarubicin+cytarabine (TA) and homoharringtonine+cytarabine (HA). All patients had a 14 day interval between the 2 courses of chemotherapy. RESULTS: The complete remission rate after 2 courses of induction therapy in patients with the priming induction regimen CAG and the total efficacy rate was significantly higher than that of the routine chemotherapy patients(67.6% vs. 39%; 82.4% vs. 56.1%). Patients with unfavorable karyotypes had poor chemotherapy efficacy. The 3-year disease-free-survival (DFS) time was longer in patients with AML treated with priming induction regimen CAG than in patients treated with 2 classic routine chemotherapy regimens. Except for the muscular soreness, the hematological and non-hematological side effects in the CAG priming induction group were significantly fewer than those in the routine chemotherapy group. CONCLUSION The priming induction regimen of CAG has a significantly higher complete remission rate and an efficacy rate, fewer side effects, milder chemotherapy intensity and is more sensitive to chemotherapeutic drugs than those of the routine chemotherapy. It can shorten the duration of agranulocytosis and decrease infectious complications and increase the sensitivity of leukemia blast cells to chemotherapeutic drugs.

OBJECTIVETo explore the potential application of IFN-gamma enzyme-linked immunospot (ELISPOT) assay in the diagnosis of tuberculous epididymitis (TE) by comparing ELISPOT assay with the traditional purified protein derivative (PPD) tuberculin skin test.

METHODSWe examined 13 TE patients using an in-house ELISPOT kit, another 11 TE patients by PPD skin testing, and 57 healthy male volunteers by parallel test with both the methods.

RESULTSTwelve (92.3%) of the 13 TE cases were positive on ELISPOT assay, and 10 (90.9%) of the 11 TE cases positive on PPD skin test, with no statistically significant differences between the two groups (P > 0.05). Among the 57 healthy male volunteers, 8 (14.0%) were positive on ELISPOT, and 28 (49.1%) positive on PPD test, the latter significantly higher than the former (P < 0.001).

CONCLUSIONIn terms of sensitivity, ELISPOT assay is similar to PPD test in the examination of tuberculous epididymitis. As for specificity, ELISPOT assay seems better than PPD test in differentiating tuberculous epididymitis patients from healthy males.
