OBJECTIVE: To retrieve and collate the earliest recorded texts in ancient acupuncture-moxibustion prescriptions for chest obstruction and heart pain, and explore the acupoint composition principles. METHODS: The Excel 2016 software was used to build a data set of ancient textual records on acupuncture-moxibustion prescriptions for chest obstruction and heart pain. After the terminology related to etiology, pathogenesis, accompanying symptoms, acupoints, and treatment methods unified, the frequency statistical analysis and association rule algorithms were applied to analyze the implicit association patterns among various elements of syndrome differentiation, treatment selection, and acupoint selection in ancient prescriptions from multiple dimensions. RESULTS: The basic acupoints of high frequency in ancient acupuncture-moxibustion treatment for chest obstruction and heart pain were Daling (PC7), Neiguan (PC6), Taixi (KI3), Taichong (LR3), Shangwan (CV13), Yongquan (KI1), and Xinshu (BL15). The prescription was mostly composed of yuan-source points. Besides, the combinations of two of five-shu points, five-shu points with luo-connecting points, and yuan-source points with luo-connecting points were common. The high-frequency points were from the pericardium meridian of hand-jueyin, conception vessel, kidney meridian of foot-shaoyin, liver meridian of foot-jueyin, and bladder meridian of foot-taiyang, generally distributed on the yin part of the arm, abdominal region, the yin part of foot, the back, and the yin part of the leg. Zhigou (TE6), Zusanli (ST36), Baihui (GV20), and Jiuwei (CV15), as well as the specific acupoint combinations, were used for chest obstruction and heart pain due to qi stagnation. Moxibustion was more suitable for chest obstruction and heart pain caused by qi reversion, cold and qi stagnation. Shaohai (HT3) was invariably selected when hand tremor was accompanied; Zhongchong (PC9) combined with Daling (PC7) was selected specially for feverish sensation in the palms. Moxibustion was exclusively applied to Shangwan (CV13), and Taixi (KI3) was often stimulated with moxibustion. At Neiguan (PC6) and Daling (PC7), moxibustion was delivered in combination with acupuncture (high confidence was presented in acupuncture). CONCLUSION In ancient acupuncture-moxibustion treatment for chest obstruction and heart pain, the points of the pericardium meridian of hand-jueyin are predominant, coordinated with those of the liver meridian of foot-jueyin, kidney meridian of foot-shaoyin, conception vessel, and bladder meridian of foot-taiyang. It follows the principles of acupoint selection, "the pericardium acting on behalf of the heart", "regulating qi as the priority", "combination of yuan-source points with luo-connecting points", and "selecting nearby points along the affected meridians".

OBJECTIVETo investigate the laws of eighteen incompatible medicaments of the chest pain prescriptions based on association rules mining.

METHODThe database of chest pain prescription was established and then the chest pain prescriptions composed of eighteen incompatible medicaments were screened. The dynasty, couplet medicines, the property and flavor of drugs and preparation form were analyzed with the frequent item sets and corresponding analysis methods.

RESULTEight hundred and fifty chest pain prescriptions were collected, and 88 of them contained eighteen incompatible medicaments, taking 10.3% of all; the applications of ancient and modern chest pain prescriptions containing eighteen incompatible medicaments are significant difference (P < 0.05). Ancient formulas, mainly focus on the eastern jin dynasty and tang dynasty, are more often used than the modern formulas. The most common anti-drugs is on the Fuzi-Pinellia, Chuanwu-Pinellia; the property and flavor of drugs is bitter cold most closely; the decoction of the formulas is mostly used.

CONCLUSIONEighteen incompatible medicaments account for about ten percent of the chest pain prescription, not an uncommon side. There are certain rules for application of anti-drug compatibility to treat chest pain.

PURPOSE: To evaluate the clinical presentations, radiological characteristics, and natural history of healthy adolescents presenting with idiopathic spontaneous pneumomediastinum. MATERIALS AND METHODS: We retrospectively reviewed the simple radiographs of 14 consecutive patients (11 males) with spontaneous pneumomediastinum, who were examined over a period of 8 years, and analyzed their clinical history, radiographic findings including distribution, combined subcutaneous emphysema, mediastinal widening, pneumothorax, pleural effusion, and resolving period on follow up chest radiographs. We also obtained CT images of 7 patients for the assessment of additional information. RESULTS:The most common complaint at the time of presentation was chest pain and chest discomfort (8/14), followed by neck discomfort (6/14). The chest radiograph was of diagnostic value in all cases. The main distribution of the pneumomediastinum was cervical (14/14), upper lung (13/14) and lower lung (6/14). Combined subcutaneous emphysema was observed in 6 patients. However, there were no cases of mediastinal widening, pneumothorax or pleural effusion. Complete resolution of the pneumomediastinum on the radiograph was observed after 10 days (mean 5.6), following purely conservative treatment. There was no additional information on the CT images, as compared with that on the radiographs. Conclusions: Idiopathic spontaneous pneumomediastinum is a benign entity that usually goes undiagnosed, but which responds very well to conservative treatment.

As classical acute aortic dissection, atherosclerotic penetrating ulcers and intramural hematoma have different pathophysiology and natural history, treatment strategy should be different and, therefore, accurate differential diagnosis is necessary. However, these three aortic diseases may be indistinguishable by clinical observation and even by various diagnostic modalities such as cardiac echocardiography, CT and MRI. The patients was a 71-year-old female with chief complaints of anterior chest pain, nausea and vomiting which occurred suddenly 3 days before admission. CT angiography with 3 dimensional reconstruction shows intramural hematoma in ascending aorta, aortic arch, descending thoracic aorta and right brachiocephalic trunk, hemopericardium, and blood in mediastinum and both pleural cavities. The CT angiographic finding of focal out-bulging in the ascending thoracic aorta was diagnosed as penetrating atherosclerotic ulcer. The patient underwent emergency operation under a preoperative diagnosis of penetrating atherosclerotic ulcer with a sign of aortic rupture. In the intraoperative findings, however, intimal tear was seen in the anterior portion of the ascending aorta about 1cm below the brachiocephalic trunk and falselumen appeared after hematoma was removed from the layer of tunica media. We report a case of type A aortic dissection which mimicked clinical and diagnostic features of penetrating atherosclerotic ulcer.

BACKGROUND AND OBJECTIVES: Primary (idiopathic) pulmonary hypertension is a rare, progressive and fatal disease. It has been defined, by the World Health Organization, as a mean pulmonary arterial pressure greater than 25 mmHg at rest, or greater than 30 mmHg during exercise, without the apparent cause of secondary pulmonary hypertension. This study was performed to better understanding the clinical presentation, natural history and prognosis of primary pulmonary hypertension. SUBJECTS AND METHODS: A total of 18 patients, who were diagnosed as primary pulmonary hypertension, at three University Hospitals, were retrospectively reviewed. All patients had undergone echocardiography and cardiac catheterization. RESULTS: With the patients there was a male: female ratio of 1:8, ranging in age between 10 and 50 years. The most common presenting symptom was dyspnea on exertion, with other symptoms comprising of fatigue in 11, chest pain in 5, syncope in 3 and hemoptysis in 2. The ECG & echocardiography reflected the presence of right-sided heart enlargement. The average right ventricular systolic pressure, from Doppler echocardiography, was 73.6+/-18.8 mmHg. The mean pulmonary artery pressure and pulmonary capillary wedge pressure were 52.9+/-18.4 and 9.2+/-3.1 mmHg, respectively. The survival times were within 30 and 21 to 60 months in 9 and the remaining patients, respectively. CONCLUSION: We conclude that primary pulmonary hypertension is common in female patients in their third to fifth decades. This study also showed a poor prognosis, as in other reports.

OBJECTIVE: Adenoid cystic carcinoma is a relatively slowly growing malignant tumor. Probably at least 40-50% of patients eventually develop distant metastases. We present the natural history and treatment modality of this malignancy from our experience and review of literature. METHODS: We report a case of a 30-year-old man who complained of a headache, facial pain and hearing disturbance in the right ear. Physical examination revealed soft, protruded mass and narrowed external auditory canal. The cranial MRI showed a well defined mass in the extradural middle cranial fossa. RESULTS: The patient underwent subtotal resection of the lesion after tumor embolization was performed. The pathological diagnosis was adenoid cystic carcinoma. The patient received postoperative radiation therapy(56Gy) resulting in a complete neurological recovery. Fifteen months later, the patient was readmitted for severe back pain. Bone scan disclosed hot uptakes at the upper cervical spine, the 4th lumbar vertebra, and the pelvic area. These areas were irradiated(40Gy) and the presenting symptoms were relieved. Twenty months later, he complained of respiratory difficulty and was found to have a multiple nodule(s) in the lung. He was given 10 cycles of chemotherapy but discharged because of unresponsivencess and development of new lesions. Brain MRI and bone scan were checked 10 months after his discharge due to more aggravated lung metastasis although local tumor was controlled. Adjuvant radiation therapy(18Gy) was performed and he continued to be functional independently, although he was no longer working as a registered nurse. Two months later, dyspnea and hemoptysis were more improved and chest X-ray showed decreased mass. During the follow up period, he complained of intercostal pain, chest X-ray showed more aggregated lung mass. Chest CT scan showed multiple lung metastases and liver metastasis. In spite of adjuvant radiotherapy, the patient died of multiple systemic metastases 47 months after the first operation. CONCLUSION: Surgery is essential in the treatment of adenoid cystic carcinoma. Radiotherapy has gained acceptance as a palliative therapy, as it reduces tumor bulk and relieves symptoms. The combined treatment do not, however, prevent further recurrence and distance metastasis.

STUDY OBJECTIVE: We evaluate the clinical characteristics and natural history of patients presenting with spontaneous pneumomediastinum (SPNM) . DESIGN: A retrospective case series was conducted to identify patients diagnosed with SPNM. ICD-7(J98.2) discharge codes were used for Jan. 1993 to Aug. 1996 at four institutions , and emergency department(ED) records and admission charts were reviewed. Clinical features, interventions, complications, setting, etiology, symptoms, and length of hospital stay were recorded. PARTICIPANTS: All ED patients more than 12 years old with a diagnosis of SPNM. RESULTS: Thirteen cases were identified. Age range was 14 to 58 years(mean 24 years). Presenting symptoms were chest pain in eight(62%), dyspnea in six(46%), both symptoms in three(23%), no complaints in three(23%). Seven(54%) patients complained only of throat discomfort. Seven(54%) had subcutaneous emphysema, and two(15.3%) had a small pneumothorax. Two(15.3%) were smokers. Three(23%) had normal esophagograms and another three had normal chest CT findings. Two cases(15.3%) were associated with inhalational drug use and three cases were due to exercise. Nine cases(69%) had a history of "Valsalva-type" maneuver. Two patients(15%) had a history of antituberculous treatment and one(7.7.%) had suffered from bronchial asthma. Mean hospital days were 7.3 days(range 3 to 14), none of all needed any intervention. Specifically, no patient developed a subsequent pneumothorax or airway compromise. Seven cases(54%) were received prophylactic antibiotics. CONCLUSION: Most simple SPNM cases are benign disease and most of them(78%) had shown typical chest pain, dyspnea and subcutaneous emphysema. Inhalational drug use is not a main cause of SPNM yet, but increase in use of bronchoinhalers is a suspicous cause of SPNM.

HCM(=Hypertrophic Cardiomyopathy) is a primary cardiac disease and its characteristic morphologic abnormality is a hypertrophied and nondilated left ventriclar in the absence of another cardiac or systemic disease that itself is capable of producing left ventricle hypertrophy. The symptoms of HCM are varied and include dyspnea, orthopnea, fatigue, chest pain, palpitations and impaired consciousness. The pathophysiologic components of the disease process are left ventricular outlofw obstruction, diastolic dysfunction, myocardial ischemia, and arrhythmia. Predicting the clinical course and outcome for individual patients HCM has been difficult because of variability in natural history and the complexity in disease expression. The present report describe a patient with am asymptomatic, pathologic Q wave in whom HCM was diagnosed by echocardiography, MIBI-SPECT, coronary angiography, and left ventriculography.
