摘要：Zhi Ling Tang (ZLT [symbol: see text], a TCM prescription designed for replenishing essence, supplementing marrow, invigorating qi, warming yang, removing blood stasis and phlegm, tonifying the brain, and invigorating mental activity) was used in 32 cases of senile dementia (SD). After treatment, the levels of serum cholesterol (Tch), triglyceride (TG), and plasma lipid peroxides (LPO) were lowered; the content of high density lipoprotein (HDL) and the activity of superoxide dismutase (SOD) in RBC significantly elevated, the cerebral blood flow was increased; latent period of P300 and P3 waves was shortened while the amplitude of P3 elevated; and topographic electroencephalogram, revised Hasegawa dementia scales (HDS) scores (P

摘要：OBJECTIVE: To study the application of dental implant distractor (DID) in mandibular functional reconstruction. METHODS: We designed a new device named DID, which includes the permanent dental implant and the temporary distractor in itself. It is specially designed for fibula wider distraction in mandible reconstruction. Twenty-five sets of DID devices were put into 8 patients (6 men and 2 women) during operation. Two patients suffered from ameloblastoma of the mandible, 2 from odontogenic cyst of the mandible, 1 from fibrous dysplasia, and the other 3 from malignant tumor of the mandible. The age of 8 patients ranged from 19 to 67 (mean 46.8) years. RESULTS: During postoperative 2 - 15 months follow up, 7 patients were found to be successful. The clinical examination and X-ray film showed the normal shape of the mandible and the osteointegration of the implants were solid enough to withstand the denture force. Others had the DID removed because of inflammation. Two of the patients successfully worn the fixed dental prosthesis. The outcomes was satisfying. CONCLUSION: The DID device specially designed for mandibular reconstruction with fibular flap can help to simplify convenient procedures to a single surgery.

摘要：OBJECTIVE: To study the potential and advantages of internal distraction osteogenesis in mandibular functional reconstruction. METHODS: Three types of mandibular distractors were used in eight patients with various mandibular defects due to tumor or cyst resection. The average age of the patients was 31.5 years old (ages ranged from 8 to 54 years). For two patients with ramus defects, specially designed distractors were used to restore the normal ramus height. In two other patients, specially designed trifocal distractors were used. In three patients, vertical distractors were used. RESULTS: All the mandibles were successfully reconstructed in accordance with the direction and distance designed before operation except in one patient. In that patient the distal 23 mm defect failed to be corrected because of loosening of transport block fixation screws. CONCLUSIONS: Mandibular defects can be successfully corrected using internal distraction osteogenesis. Performing mandibular reconstruction using distraction osteogenesis is best done at the time of tumor or cyst resection.

摘要：OBJECTIVE: To apply fractionated-clamping for repair of thoracoabdominal aortic aneurysm (TAA), and evaluate its effects in decreasing surgical mortality and severe complications, such as renal failure and paraplegia, a modified crawford procedure were prospectively evaluated. METHODS: Using modified shunting and cross-clamping techniques, modified Crawford repair in 13 thoracoabdominal aorta patients were performed in the Vascular Division at Peking Union Medical College Hospital. TAA Crawford classification: 1 type I, 2 type II, 2 type III and 3 type IV TAA. Debakey classification: 1 type I, 4 type III (including 2 ruptured aneurysms), and 1 aortic coarctation. RESULTS: Thirteen procedures were performed successfully. One died of ventricular fibrillation just before completing the operation. Surgical mortality rate was 7.7% (1/13). Postoperative complications included 1 acute necrotic pancreatitis, 1 ARDS, 1 paraplegia, 1 acute renal failure, and 2 thoracic cavity bleeding. Total complication rate was 53.8% (7/13). CONCLUSIONS: Fractionated-clamping in thoracoabdominal aortic aneurysm repair is our modified Crawford procedure and aortic bypass. Clinical results demonstrate that our procedure decreased surgical mortality and major complication rate, and also alleviated viscera ischemic injury. Fractionated-clamping in aorta replacement is a practical procedure for TAA repair under general anesthesia at normal temperature.

摘要：OBJECTIVE: To analyse the characteristics and therapies of patients with acute ischemic syndrome in China.　 METHODS: This study is part of the international multicentre registry for acute ischemic syndrome. Since April 1999, the data of patients admitted to designated hospitals with acute ischemic cardiac chest pain were collected by filling in Case Report Forms offered by the Canadian Cardiovascular Collaboration. The main clinica l characteristics and in　hospital events of the patients were recorded.　 RESULTS: Fifteen hundred and nine cases of acute ischemic syndrome from 34 hospitals nationwide were enrolled in the registry (including unstable angina and non Q-wave myocardial infarction).The mean age of the patients was 62.3. male dominance (62.2%) was noted. The percentages of patients with chest pain at presentation and abnormal ECG were 47.8% and 89.5%, respectively. The most common clinical diagnosis on admission was unstable angina, accounting for 91.3% of the patients and non Q-wave myocardial infarction (MI), accounting for the other 8.7%. During hospitalization, the following interventions were given: thrombolytic therapy in 50 cases (3.3%), coronary angiography in 528 cases (35.0%), percutaneous transluminal coronary angioplasty (PTCA) in 253 cases (16.8%) and coronary artery bypass graft surgery (CABG) in 62 cases (4.1%). Nitrate (oral or patch ) and anti-platelet therapy were used in 1460 cases (96.8%) and 1441 cases (95.5%), respectively. The incidence of in　hospital major events was 18.8%, in cluding 18 deaths (1.2%), with the most common causes being severe arrhythmias and sudden death.　 CONCLUSIONS: Patients with acute ischemic syndrome in China have mostly been diagnosed as cases of unstable angina. A relatively high PTCA rate but low CABG rate was noted in China. The most common cause of in　hospital death is severe arrhythmias or sudden death.
