The Philippines’ medical system is mainly based on the provincial responsibility system and the limited hierarchical. The Philippine government implement Philhealth program which can provide medical insurance for most people. The top 10 fatal diseases in this country includes ischemic heart disease, stroke, lower respiratory tract infection and so on. Of these diseases, the increasing rate of hypertensive heart disease, chronic kidney disease and diabetes are fast. Bone setting, massage and herbal medicine are the major form of traditional medicine in the Philippines. The acceptance of acupuncture and moxibustion by the government and local people is relatively high acupuncture and moxibustion therapy has been included in its medical insurance. There are many limitations on the development of Traditional Chinese Medicine (TCM) theory and Chinese herbal medicine in the Philippines, and the clinical application of acupuncture and Chinese herbal medicine is still limited. TCM education in the Philippines is still not systematic. Therefore, it is suggested to improve the education system of TCM, strengthen the promotion of acupuncture and moxibustion, give full play of the advantages of TCM for native high-risk diseases, and to make use of modern technologies such as telemedicine.

Objective To explore the feasibility, safety and preliminary efficacy of radioactive gastric tube of 125Ⅰ seeds in the treatment of advanced esophageal carcinoma. Methods For 10 cases with advanced esophageal carcinoma, the tumor target area was outlined in the TPS system according to preoperative CT images. Prescription dose was 60 Gy with 125Ⅰ seed radioactivity of 2. 22 × 107 Bq. Accordingly, the 125Ⅰ seeds number and the appropriate gastric tube was decided. Then, depending on the location of the tumor and certain rules, 125Ⅰ seeds were fixed in the tube wall to make the radioactive 125Ⅰ seeds gastric tube. Under the C-arm X-ray fluoroscopy, the radioactive 125Ⅰ seeds gastric tubes were placed into esophageal carcinoma site of the patients. Results The radioactive 125Ⅰ seeds gastric tubes of 10 patients were successfully placed, without esophageal perforation, bleeding complications and so on. In one month after operation, all patients with dysphagia′s Stooler classification score were 2 -3 level,of which one case died of other basic diseases in three months after operation, and six cases achieved 0 -1 level while the other three cases achieved 1 -2 level in four months after operation. There were no cases of postoperative chest pain, bleeding, pneumonia and other related complications. Conclusions The radioactive 125Ⅰ seeds gastric tube could not only help to solve nutrition problems, but also the intracavitary brachytherapy inhibit the growth of tumor, which is safe and feasible in clinical use. It can be used as a palliative treatment for patients with advanced esophageal carcinoma.

Meridian theory plays an important role in the guidance of clinical practice of acupuncture and moxibustion. Since the publication of(), the meridian theory has been developed. In the paper, in view of complex science, the topological properties of acupoint-symptom network were analyzed quantitatively by taking acupoint as node and indication as the connection, such as high clustering coefficient and the small world effect. It was the first time to give the abstraction for the topological proof of the high efficiency information transmission property of acupoint-symptom network meridian system at different times. Its quantitative and digitalized significance was analyzed on the development of meridian theory under the complex scientific background so as to provide a new thought and method for the study of meridian theory and acupuncture modernization.

OBJECTIVE To study the “property-effect” correlation material basis of the classic famous prescription Taohe chengqi decoction in removing blood stasis and purging heat. METHODS The rat model of blood storage syndrome was established to investigate the effects of Taohe chengqi decoction （17.29 g/kg） and its property grouping components [bitter-cold property group （Rhei Radix et Rhizoma+Natrii Sulfas） 9.43 g/kg， pungent-warm property group （Cinnamomi Ramulus+Persicae Semen） 4.71 g/kg， sweet-flat property group （Glycyrrhizae Radix et Rhizoma） 3.14 g/kg] on coagulation indexes （prothrombin time， prothrombin activity， activated partial thrombin time， fibrinogen， thrombin time and endothelin-1） and inflammation indicators （C- reactive protein， tumor necrosis factor-α and superoxide dismutase） in rats. On the basis of determining the dominant property groups， ultra-performance liquid chromatography-quadrupole-orbitrap high-resolution mass spectrometry was used to identify the components. The molecular docking was performed， and the components with binding energy ≤－5.0 kcal/mol were selected as the basis of “property-effect” correlation material basis. RESULTS Taohe chengqi decoction total prescription group and pungent-warm property group could significantly improve the coagulation indexes of model rats （P＜0.05 or P＜0.01）， and the total prescription group and bitter-cold property group could significantly improve the inflammation indexes of model rats （P＜0.05 or P＜0.01）. The pungent-warm property group was the dominant property group for removing blood stasis，and the bitter-cold property group was the dominant property group for purging heat. Thirty-two and thirty-five components were identified from the pungent-warm property group and bitter-cold property group， respectively. With binding energy ≤－5.0 kcal/mol， there were 10 components （abscisic acid， 3，4-dihydroxypheny- lethanol， procyanidin B1， etc.） in the pungent-warm property group and 13 components （baicalein， aloe-emodin， demethylwedelolactone， etc.） in the bitter-cold property group. CONCLUSIONS Taohe chengqi decoction has the effect of removing blood stasis and purging heat， and its material basis comes from pungent-warm property group （Cinnamomi Ramulus， Persicae Semen） and bitter-cold property group （Rhei Radix et Rhizoma， Natrii Sulfas） respectively.
