Qi Deficiency syndrome and Blood Stasis syndrome were the two syndrome elements seen most frequently. Conclusions: The syndrome elements extracted by entropy-based complex system partition method and their distribution rule can reflect the pathogenic characteristics of angina pectoris, which lays a base of quantify the diagnostic criteria of the angina pectoris syndrome.

Translational medicine, a kind of medical scientific practice oriented by patients'demands, emphasizes that basic theoretical study helps enhance clinical effect, transform into new drugs as well as meet major needs of social development and human health. It follows disciplinary development rules of TCM, persists in five-in-one (theory-clinic-new drug-experiment-evidence based) innovative new mode of TCM translational development, accelerates internal transformation of research findings, and promotes clinical effect and disciplinary development driven by the oretical innovation of collateral disease. In terms of the oretical research, establishment of new discipline of TCM collateral disease theory has become a practitioner and typical representative for promotion of TCM industry development. Important position and guiding role of theoretical innovation in disciplinary development has been valued. Systematically constructing ″collateral disease treatment based on syndrome differen?tiation″ and ″meridian-collateral theory″ lay a theoretical foundation for establishment of the discipline. With regard to clinical research, under the guidance of TCM theory-collateral disease theory, systematic researches on Chinese medical pathogenesis, intervention strategy and effective formula of major diseases are conducted; series of innovative Chinese medicines are developed. Through pharmacody?namics study, relevant action mechanisms are investigated and revealed in- depth. Evidence- based medical researches prove that representative activating-collateral drugs developed under guidance of collateral disease theory have great application values in prevention and treatment of major refractory diseases such as ischemic cardio-cerebrovascular disease, arrhythmia, chronic heart failure, influenza, tumors and diabetes, bringing about significant economic and social benefits. In this way, international cooperation is promoted and internationalization process of innovative Chinese medicine is accelerated. USA FDA phase-Ⅱ clinical research of Lianhua Qingwen Capsules has been successfully launched. Guided by inheritance and innovation of conventional theory of TCM, the new five- in- one mode of development is established. Such a mode conforms to disciplinary development rules of TCM, suffi?ciently exerts core driving effect of TCM theory, realizes combination of theoretical innovation with clinical practice, specialty construction with disciplinary development and clinical research with original new drug, as well as powerfully promotes progress of TCM collateral disease discipline.

Objective To investigate the relationship of fetal total bile acid (TBA) concentration with the change of fetal pancreas endocrine secretion and its impact on fetal growth and development in intrahepatic cholestasis of pregnancy(ICP). Methods The concentrations of TBA, insulin, glucagon and glucose in the cord blood were measured in 30 fetuses with maternal ICP (case group) and 30 fetuses of normogravidas(control group) after elective cesarean section during the same period in the Department of Obstetrics of Xiangya Second Hospital of Central South University from March 2007 to February 2008. The cord blood TBA concentration was investigated by enzyme method and the concentrations of insulin and glucagon were investigated by radioimmunoassay. The glucose was measured by oxidase-superoxide method. The neonatal weight, length and the ponderal index (PI) were measured after parturition. Results (1) The cord blood insulin concentration (9.0±3.3) mU/L and the ratio of insulin over glucagon 0. 048±0. 028 in the case group was significantly lower than that of controls(10.1±3.7) mU/L,0.050±0. 020 (P<0.05). The concentrations of TBA(10.3±3. 8)μmol/L and glucagon(235±57) ng/L in case group were obviously higher than that in controls (4.1±1.3)μol/L, (205±34) ng/L(P<0.05). But no difference was shown in the glucose concentration in cord blood between the ease and control groups [(3.4±1.1) mmol/L vs (3.6± 1.2 )mmol/L, P > 0.05]. (2)The neonatal weight and length in case group were significantly lower than that of control [(3163±478) g vs (3498±393)g, (46.5±2.3) cm vs (49.3±1.9)cm, P<0.01]; while the Ponderal index in ease group was significantly higher than that of control group (3.13±0. 23 vs 2. 92±0. 29,P <0.01). (3) The cord blood TBA concentration respectively showed a linear relationship with the cord blood insulin concentration, the cord blood glucagon concentration and the ratio of insulin over glucagon in the case group. With the increase in cord blood TBA concentration, the cord insulin concentration and the ratio of insulin over glucagon decreased; meanwhile the cord blood glucagon concentration rose(P<0.01). The cord blood insulin concentration and the ratio of insulin over glucagon in case group were respectively positively correlated with the neonatal weight and length, and were negatively correlated with the PI (P<0.01); while the cord glucagon concentration was respectively negatively correlated with the neonatal weight and length, and positively correlated with the P1 (P < 0.01 ).Conclusions In 1CP fetus pancreas, there are hypoinsulinism, glucagon oversecretion, and decrease of the ratio of insulin over glucagon, which is closely correlated with fetal TBA concentration. The endocrine function of fetal pancreas affects the fetal growth and development.

This paper uses the Luobing theory to guide the diagnosis and treatment of coronavirus disease-2019 (COVID-19), and states that lung collateral includes Qi collateral and blood collateral, and is the basis for playing the function of lung of dominating Qi, controlling breathing and connecting all vessels. The concept of Qi channel is different from that of Qi collateral, but its function is closely related to lung collateral. COVID-19 belongs to "pestilence" in traditional Chinese medicine. The epidemic pathogenic factor enters from mouth and nose and then causes the disease. The early characteristics of this disease include the invasion of the lung by the epidemic pathogenic factor, the obstruction of Qi channels, the prevailing of the evil and the retreat of the good, and the deficiency and stagnation of Qi collateral. Generation of toxic heat from inside, obstruction of Qi channels and dysfunction of "breathing and blood transfer" are the key links to the development and aggravation of this disease. Qi disease involves blood, blood wound intrudes into collateral, and blood consumption and hemorrhage are the late outcome of this disease. Based on the experience of doctors of all dynasties in the treatment and medication of pestilence, the treatment principle of active intervention in the early and middle stage is proposed, including focusing on pathogenesis and expelling of toxin, drug use before syndrome onset and active intervention, and the whole regulation and multi-target treatment. Lianhua Qingwen developed under the guidance of Luobing theory can inhibit the activity of novel coronavirus in vitro, relieve clinical symptoms (such as fever, cough, weakness, shortness of breath and so on) and reduce the rate of disease progression to severity. Lianhua Qingke can diffuse the lung, clear the lung heat, relieve cough and reduce sputum. It can be used to relieve the symptoms of cough and sputum in patients with COVID-19, which proves the important scientific value of Luobing theory and collateral-dredging drugs in epidemic prevention and control.

Objective To evaluate the clinical value of quantitative tissue velocity imaging (QTVI) in assessing left ventricular(LV) global and regional myocardial function in patients with mitral valve replacement(MVR).Methods Eighty patients having their implantations for more than six months were examined by echocardiography.QTVI-derived parameters such as peak systolic velocity(Sa,Sm) and early diastolic velocity(Ea,Em) of mitral annulus and LV wall were measured from the apical four-chamber,two-chamber and long axis corresponding myocardial segments in MVR groups decreased and LV ejection fraction but negative correlation between Ea' and isovolumic relaxation time(IVRT') in patients(P<0.01).Conclusions QTVI plays an important role in determining LV function of patients after MVR accurately.

Objective To study the effects of low power laser irradiation in nasal cavity on cerebral blood flow and cerebral function in patients with brain infarction. Methods Thirty-nine patients with cerebral infarction were divided into a intravenous laser irradiation group and a laser irradiation in nasal cavity group. For the group of intravenous irradiation (ILIB group,18 cases), the patients lay on the bed with their heads fixed and were treated with intravenous laser irradiation for 30 min. Both before and after the therapy they received a SPECT cerebral perfusion imaging separately. For the group of laser irradiation in nasal cavity (LINC group,21 cases), the patients received laser irradiation in nasal cavity for 30 min and also SPECT cerebral perfusion imaging tests both before and after therapy. BFCR% model was used to quantify the blood flow of the focal and mirror regions. Results SPECT showed that there was significant improvement in perfusion of the entire brain and cerebral function in both ILIB and LINC groups after 30 minutes of treatment,each compared to those before treatment; the changes in the focal rCBF and cerebral function were much more obvious (P0.05). BFCR% in focal region was significantly higher than that in mirror region (P0.05). Conclusion Low power laser irradiation in nasal cavity can improve the focal rCBF and cerebral function of the patients with brain infarction, which is similar to that of the ILIB.

Objective To examine the clinical effect of simultaneous intervention for heart and lung on chronic obstructive pulmonary disease (COPD) of stationary phase combined with stable angina pectoris with Qi deficiencyblood stasis-phlegm blockade syndrome.Methods Ninety-six COPD stationary phase combined with stable angina pectoris patients with Qi deficiency-blood stasis-phlegm blockade syndrome were randomized into control group,Juhong [Exocarpium Citri Rubrum] tablet group,the Tongxinluo (通心络) group and the Ju&Tong group,24 cases in each group.The control group was given western medicine routine therapy.In addition to the treatment of the control group,Juhong tablet 3.6 g was given to the Juhong tablet group orally,twice each day;Tongxinluo capsule 1.04 g was given to the Tongxinluo group orally,three times each day;Juhong tablet and Tongxinluo capsule were given to the Ju&Tong group.Each group was treated for 8 weeks.The following intems were compared before and after treatment including the scores of cough,cough up phlegm,dyspnea and St.George's Respiratory Questionnaire (SGRQ),anginal attacks,durante dolors,nitroglycerin consumption,pulmonary function [including forced expiratory volume in one second (FEV1) and forced vital capacity (FVC)],as well as the levels of serum C reactive protein (CRP),interleukin 1β (IL-1β) and interleukin 10 (IL-10).Results After treatment,the scores of cough,cough up phlegm,dyspnea and SGRQ decreased in the Juhong tablet group,the Tongxinluo group and the Ju&Tong group.FEV1 and FVC increased.Anginal attacks,durante dolors,nitroglycerin consumption,as well as the levels of serum CRP,IL-1 βand IL-10 decreased.Moreover,the effect of certain indexes in the Ju&Tong group was superior to those in the Juhong tablet group and the Tongxinluo group (P ＜ 0.05 or P ＜ 0.01).Conclusion Simultaneous intervention for heart and lung might improve clinical symptoms and pulmonary function of COPD stationary phase combined with stable angina pectoris with Qi deficiency-blood stasis-phlegm blockade syndrome patients.Inhibiting chronic persistent inflammation might be one of the important mechanisms.
