The paper reviews the evolution of the theory related to meridians and zangfu organs during the Warring States, Qin and Han dynasties, so as to reveal the rules and value of its development. By analyzing historical documents, especially Zubi Shiyimai Jiujing (Moxibustion Classics of Eleven Meridians of Legs and Arms), Yinyang Shiyimai Jiujing (Moxibustion Classic on Eleven Yin and Yang Meridians), Laoguanshan bamboo medical slips of Han Dynasty and lacquer figure of meridian points, the evolutionary stages, i.e. the germination, development, and maturity of meridian-zangfu theory, are explored. In the time of the Warring States, Qin and Han dynasties, the meridian-zangfu related theory was developed from the germination to the maturity. In the classics of the early time, Zubi Shiyimai Jiujing and Yinyang Shiyimai Jiujing demonstrated the preliminary relationship between meridians and zangfu organs, focusing on the physiological connection and pathogenesis of three yin meridians of foot and zangfu organs. In the literature of Laoguanshan bamboo medical slips of Han Dynasty and lacquer figure of meridian points, the physiological connection between the yin meridians of hand and foot, and five zang organs, as well as the related diseases were further clarified; additionally, the meridian-zangfu theory had been developed in the field of diagnosis and treatment. In the era of Chapter of Meridians in Lingshu (Miraculous Pivot), there were up to 31 descriptions relevant with the connection of meridian distribution and zangfu physiological functions. It marks the construction of the "circular" flow of meridians and the interior-exterior communication of zang and fu organs; and enriches the knowledge in diseases, diagnosis and treatment with meridians and zangfu organs involved. The review on the evolution of the meridian-zangfu theory is conductive to supplementing and improving the development history of this theory of early time, and further recognizing its development rules and value. The maturity of this theoretical system not only links the meridians with the five zang and six fu organs, but also provides an important theoretical basis for the diagnosis and treatment of traditional Chinese medicine.

Objective To explore the effects of different acupoints,different target organs,and different interventions on acupoint efficacy based on ACU&MOX-DATA platform;To illustrate and visualize whether the above factors have the characteristics of"specific effect"or"common effect"of acupoint efficacy.Methods The multi-source heterogeneous data were integrated from the original omics data and public omics data.After standardization,differential gene analysis,disease pathology network analysis,and enrichment analysis were performed using Batch Search and Stimulation Mode modules in ACU&MOX-DATA platform under the conditions of different acupoints,different target organs,and different interventions.Results Under the same disease state and the same intervention,there were differences in effects among different acupoints;under the same disease state,the same acupoint and intervention,the responses produced by different target organs were not completely consistent;under the same disease state and acupoint,there were differences in effects among different intervention measures.Conclusion Based on the analysis of ACU&MOX-DATA platform,it is preliminary clear that acupoints,target organs,and interventions are the key factors affecting acupoint efficacy.Meanwhile,the above results have indicated that there are specific or common regulatory characteristics of acupoint efficacy.Applying ACU&MOX-DATA platform to analyze and visualize the critical scientific problems in the field of acupuncture and moxibustion can provide references for deepening acupoint cognition,guiding clinical acupoint selection,and improving clinical efficacy.

Neuropsychiatric disorders such as Parkinson disease,Alzheimer disease,and schizo-phrenia may induce hallucinations,delusions,and other psychiatric symptoms during the course of disease development.These symptoms are highly prevalent and difficult to cure,and have a impact on the lives of patients.Classical antipsychotic drugs such as chlorpromazine,sulpiride and perphenazine can con-trol related symptoms,but they can also cause uncontrollable extrapyramidal system reactions and side effects such as hyperprolactinemia.In recent years,it has been found that non-classical antipsy-chotics such as olanzapine,clozapine,risperidone and pimovanserin can treat hallucinatory symptoms in neuropsychiatric disorders by antagonising the 5-hydroxytryptamine 2A(5-HT2A)receptor,or by antago-nising both the 5-HT2A receptor(strong)and the dopamine 2(D2)receptor(weak).In preclinical studies,non-classical antipsychotic drugs have shown great therapeutic effects against hallucination induced by multiple factors.Clinical studies have confirmed that these drugs improve psychotic symptoms(mainly hallucinations and delusions)significantly.In patients who are insensitive or tolerant to clozapine and risperidone,pimavanserin still shows therapeutic effects.At the same time,the incidence and severity of adverse reactions to non-classical antipsychotic drugs are reduced,and they are well tolerated.This article reviews the research progress in the role of 5-HT2A receptor antagonists in attenuating hallucino-genic symptoms so as to provide reference for the design and development of new therapeutic drugs.

Objective To explore how to achieve isolation of clinical trial fees and general medical expenses of hospitalized subjects through information technology.Methods This article analyzed various methods for separating clinical trials fees from medical insurance and suggested that all methods need to protect subjects'medical insurance reimbursement rights and ensure that they do not occupy medical insurance funds.Based on this principle,A clinical trial cost segregation information module was developed based on inpatient's workstation.Results Through this information module,subjects could choose their medical status according to the actual medical situation.Doctors could issue medical orders in hospital information system(HIS)according to normal medical or trail needs,change the nature of the orders by adding or deleting clinical trial tags.The system automatically intercepts the clinical trial orders for reimbursement of medical insurance,while other expenses are reimbursed according to rules of medical insurance.Conclusion The application of this information module has improved the subjects'enthusiasm and compliance to participate in clinical trials,reduced their economic burden,and ensured their rights to enjoy reimbursement of medical insurance,which can be used as a reference example for newly registered clinical trial institution.

Objective:To observe the effects of ointment and massage on inflammation, oxidative stress and angiogenesis after skeletal muscle trauma, and to explore their mechanisms.Methods:Forty-two adult male Sprague-Dawley rats were randomly divided into a blank group ( n=6), an ointment and massage (O&M) group ( n=18) and a model group ( n=18). The blunt contusion model of gastrocnemius malformation was established in both the O&M and model groups using self-made percussion instruments. Two hours after successful modeling, the anti-inflammatory pain-relieving cream was applied to the injured area, and massaged evenly and gently for 5 minutes. That was repeated with an interval of 12 hours. No treatment was given to the model and blank groups. On the 1st, 3rd and 7th days after modeling, injured gastrocnemius muscles were resected after collecting abdominal blood. Hematoxylin-eosin (HE) staining and immunofluorescent (CD34) staining were applied, and serum superoxide dismutase (SOD) and malondialdehyde (MDA) contents were detected. Results:HE staining showed that at each time point the gastrocnemius muscle fibers of the model group were significantly more swollen and deformed, collapsed and dissolved than those of the blank group, with a large number of inflamed cells. The O&M group had better recovery, with more newly-generated muscle cells, less inflammatory infiltration and more normal cell shapes than the model group. Fluorescence was stronger in the O&M and model groups than in the blank group at each time point, with that of the O&M group significantly stronger than in the model group. The average SOD and MDA levels in the model and O&M groups were significantly higher than in the blank group, and on the 1st and 3rd days the O&M group′s average SOD level was significantly higher than the model group′s average, though by the 7th day there was no significant difference. The average MDA content of the O&M group was significantly lower than the model group′s average at each time point.Conclusion:Ointment and massage can effectively reduce the local inflammatory response and oxidative stress after a skeletal muscle injury. They can accelerate local angiogenesis, promoting the repair of damaged tissues.

Clinical undergraduates generally have the following problems during their radiology internship: short internship period, low motivation, teachers using traditional teaching mode, and insufficient hardware and software facilities for image reading. In this study, RadiAnt DICOM Viewer and case-based learning (CBL) model were applied in online practice teaching for clinical undergraduates in the radiology department, which achieved good results. The results showed that the clinical undergraduates had a pass rate of 91.18% (124/136) in the image reading quiz and a mean score of (85.71±10.99) in the in-class quiz, with a pass rate of 91.91% (125/136). The satisfaction survey showed that 84.56% (115/136) of the students were more satisfied with the application of RadiAnt DICOM Viewer in image reading teaching; 80.88% (110/136) of the students expressed more interest in radiology after this training course; 90.44% (123/136) of the students thought that online practice teaching of radiology is feasible.

ObjectiveThe functional model of six major components of Astragali Radix-Angelicae Sinensis Radix combination against the proliferation of vascular smooth muscle cells （VSMCs） was constructed by uniform design， the relationship between the compatibility of these six main components and the inhibition of VSMCs proliferation was analyzed， and the effect of the compatibility of these main components of Astragali Radix-Angelicae Sinensis Radix on the proliferation of VSMCs as well as the feasibility of uniform design test in the study of multi-component compatibility of Chinese medicines were discussed. MethodCell proliferation and toxicity assay kit （CCK-8） method was used to determine the inhibitory effect of the six components of Astragali Radix-Angelicae Sinensis Radix on platelet derived growth factor-BB （PDGF-BB）-induced VSMCs proliferation in rats and the half inhibitory concentration （IC₅₀） of each component were obtained. Six chemical components of Astragali Radix-Angelicae Sinensis Radix （formononetin， astragaloside Ⅰ， astragaloside Ⅳ， calycosin， ferulic acid and calycosin-7-O-β-D-glucoside） were taken as the independent variables X₁， X₂， X₃， X₄， X₅， X₆， respectively， and the cell proliferation inhibition rate as the dependent variable Y. U24*（24⁹） uniform design table and mathematical models （including linear and quadratic polynomial） were selected， the stepwise regression method was used to screen the variables， and the better equations were obtained in theory. The actually better relationship equations were screened by setting the different dose compatibility of these six components for verification tests. According to the purpose of the experiment， the selected regression equation was processed by data centralization， so as to compare the regression coefficients of the data centralization equation and analyze the correlation between components and efficacy. ResultThe six components of Astragali Radix-Angelicae Sinensis Radix could inhibit abnormal proliferation of VSMCs in a dose-dependent manner. IC₅₀ values of formononetin， astragaloside Ⅰ， astragaloside Ⅳ， calycosin， ferulic acid and calycosin-7-O-β-D-glucoside were 123.453， 113.184， 81.655， 141.159， 101.187， 151.016 mg·L^-1， respectively. Two superior models were selected by experimental verification， including equation 1 of Y₁=73.137 897-0.207 888X₁+0.000 508X₂²+0.000 347X₁X₆ and equation 2 of Y₂=70.038 433-0.236 665X₁+0.000 577X₂²+0.000 260X₁X₄+0.000 415X₁X₆+0.000 370X₃X₅. After data centralization， equation 2 was adjusted to Y=-1.480 260-0.146 281X₁+0.000 673X₂²+0.000 314X₁X₄+0.000 456X₁X₆+0.000 737X₃X₅， the regression coefficients showed that the astragaloside Ⅰ had a positive effect on the inhibition rate of cell proliferation， formononetin-calycosin， formononetin-calycosin-7-O-β-D-glucoside and astragaloside Ⅳ-ferulic acid had an interaction effect on the inhibition rate of cell proliferation， and the synergistic effect of astragaloside Ⅳ and ferulic acid was higher than other interaction items. ConclusionThe combination of six main components of Astragali Radix-Angelicae Sinensis Radix can inhibit the abnormal proliferation of VSMCs， and it is demonstrated that the uniform test design can be used to predict the correlation between the chemical composition of Chinese medicines with their pharmacological effects， which can provide an experimental basis for the rational use of uniform design and regression analysis to construct mathematical models to study the compatibility relationship of Chinese medicines.

Objective To investigate the clinical effects of reparing the complicated soft tissue defects of limbs with free thoracodorsal artery perforator (TDAP) flaps.Methods From April,2009 to March,2014,19 limbs (including 8 upper limbs and 11 lower limbs) soft tissue defects with bone and tendon exposure were repaired with free TDAP flaps in the secondary stage.There were 12 thoracodorsal artery perforator flaps,5 polyfoliate perforator flaps,1 chimeric muscle flap,and 1 chimeric muscle polyfoliate flap.The sizes of the flaps ranged from 5.0 cm×6.0cm-20.0 cm×l 1.0 cm.Seventeen wounds of the dornor site were closed directly,and the other 2 were closed with skin grafts.Results Sixteen flaps survived successfully.Two flaps had venous congestion and survived at last after taking the stitches out.One flap had partial necrosis and repaired by skin graft finally.The clinical results were satisfactory after 12-18 months following-up,and the scars of the dornor sites of all but 3 patients were not obvious.All the shoulder function were normal.Conclusion The TDAP flap has dependable blood supply,good texture,less dornor site morbility.The polyfoliate TDAP flap can be used for repairing irregular defect.The chimeric latissimus TDAP flap can be used for the function reconstruction.The free TDAP flap is suited for repairing soft tissue defects of the limbs.
