Literatures on pain intervention with transcutaneous electrical acupoint stimulation (TEAS) were collected by searching the databases both in Chinese and English, and summarized to understand the research progress of TEAS effects on pain mediators in recent years. This will provide a more objective and scientific theoretical basis for clinical practice of TEAS to treat pain syndrome, thus promoting the clinical application of TEAS. Our literature analysis indicated that TEAS effectively regulated the release levels of various pain factors such as prostaglandin, 5-hydroxytryptamine, interleukins, substance P and tumor necrosis factor-α to achieve the analgesic effects by affecting the conduction pathways. TEAS is a safe, non-invasive and effective treatment for pain syndrome. However, further research is necessary due to the lack of rigor of the current clinical trial design.

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.

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 study the role of serum from asphyxiated neonates in the inducement of human renal proximal tubular epithelial cells (HK-2) adhesion to neutrophils and possible mechanisms.

METHODSHK-2 cells were cultured randomly with 20% serum from neonates (1, 3, and 7 days after asphyxia), pyrrolidine dithiocarbamate (PDTC) or placebo. The activity of myeloperoxidase (MPO), an indicator of adhesion ability of HK-2 cells to neutrophils in suspensions, was detected by the biochemistry assay. Intercellular adhesion molecule-1 (ICAM-1) and nuclear factor-kappaB (NF-kappaB) of HK-2 cells were examined with the immunohistochemical staining.

RESULTSThe expression of MPO in the post-asphyxial 1-day serum treatment group were significantly higher than that in the PDTC treatment and the control groups as well as the post-asphyxial 3 and 7-day serum treatment groups (P<0.01). The expression of ICAM-1 and NF-kappaB in the post-asphyxial 1-day serum treatment group was also significantly higher than that in the other groups (P<0.01).

CONCLUSIONSSerum from asphyxiated neonates can induce HK-2 cell adhesion to neutrophils, possibly through activating NF-kappaB and increasing the synthesis and expression of ICAM-1 on the surface of renal tubular epithelial cells.

Objective To investigate the clinical effectivity of the muscular flap transposition and induced membrane technique in the emergency treatment for the limb salvage of Gustilo type Ⅲ B/C open fracture of lower leg. Methods From July, 2015 to December, 2017, 10 cases of Gustilo type Ⅲ B/C fracture of lower leg with bone defects were performed limb salvage surgery. Induced membrane technique was used to fill the bone defects in the emergency room.The gastrocnemius and/or soleus muscular flaps were transposed to cover the bone cement or ex-posed bone simultaneously in emergence treatment. After the wound healed completely, traditional bone grafting was used to repair the bone defects. There were 4 cases of Gustilo type Ⅲ B and 6 cases of Gustilo type Ⅲ C. The aver-age length of bone defect was (5.25±1.70) cm ranging from 3.0 cm to 11.0 cm. The gastrocnemius medial head flaps were performed in 5 cases, the combined application with the gastrocnemius medial head flaps and the medial hemimuscular flaps of soleus were performed in 2 cases, and medial hemimuscular flaps of soleus were transposed in 3 cases. Results The wounds in 6 cases were healed at one stage, but 2 cases healed by dressing because the exudate after skin grafting.In 1 case, the cross-leg flap was used to cover the exposed bone cement due to the necro-sis of soleus flap. The other 1 was performed the transposition of the lateral gastrocnemius flaps because the exposure of bone cement after the necrosis of the upper and lateral muscles in lower leg. In the second-stage, the bone defects were reconstructed by traditional bone grafting. The average healed time of bone was 7.2 months ranging from 5 months to 9 months. At the last followed-up time, all patients recovered their function of weight-bearing. The Paley's score of the adjacent joints: excellent in 8 cases and good in 2 cases. Conclusion The combination with induced membrane technique and local muscular flap transposition in emergency surgery is an effective method to limb salvage for the Gustilo type Ⅲ B/C open fracture of lower leg.

OBJECTIVETo investigate the influence of molecular imprinting phenomena of traditional Chinese medicines (TCMs) on basic theories of TCMs according to current situations of molecular imprinting technology and experimental studies.

METHODFundamental principles of molecular imprinting theory were followed to analyze the material basis for TCM molecules to generate the imprinting phenomena, in order to find other material basis with more direct efficacy in line with the requirements of basic theories and modernization of TCMs.

RESULTCompared with single-component structures, TCMs and their compound components could create super-molecular compounds through complexation, composition, chelation, inclusion, neutralization, self-assembly and chemical reaction. The material basis of TCMs was super-molecular compounds including single ingredients, and there was an inter-molecule imprinting phenomenon. Therefore, special attention should be paid to inter-super-molecule imprinting actions in studies on TCM property, quality control, processing, drug preparation and pharmacology. The compatibility of TCM compounds could significantly change the action.

CONCLUSIONThe material basis of TCMs is super-molecular compounds based on single molecular groups. Super-molecules and molecular groups act rules, which is another difference between TCM compounds and single molecular drugs.

The qualitative and quantitative analysis on traditional Chinese medicine and formula components can be made by chemical and instrumental analysis methods. Of both, the instrumental analysis methods play a dominant role, including HPLC, HPLC-MS, HPLC-NMR, GC, GC-MS, biochemical and biological effect. But because traditional Chinese medicines and formula have complicated components, chemical methods are so unspecific that they shall be used less or with caution. While instrumental analysis methods are so specific that they are appropriate for analyzing complicated single component. The analysis techniques for multiple components of traditional Chinese medicines and formula focus on fingerprints, but all of these analysis techniques are limited by the pre-requisite of separation and the lack of general-purpose detectors and therefore being hard to realize the determination of all components of traditional Chinese medicines and formula. In the natural world, however, organisms identify native and alien components through specificity and non-specificity of clusters decided by antigens and antibodies. For example, components of traditional Chinese medicines are directly or indirectly synthesized into antigens and injected into animals, in order to generate specific antibodies and then collect cross reaction information of these components to specific antibodies. As for components without cross reaction, their contents shall be directly read out on the basis of the inhibition rate curve of competitive reaction for specificity of antigens and antibodies. Besides, a cross inhibition rate matrix shall be established first, and them a multiple regression linear equation between cross component concentration or concentration logarithm and inhibition rate by labeling the immunity competitive reaction between antibodies and haptens of traditional Chinese medicine and compound components, and then solved to obtain concentration of each component. The two results are combined to establish the synthetic immunity chip method for traditional Chinese medicine and formula components.
