Evaluation of the permeability mainly focuses on intestinal absorption in biopharmaceutics classification system (BCS). It is more complicated that the absorption and metabolism under multicomponent environment in biopharmaceutics classification system of Chinese materia medica (CMMBCS) compared with single component environment, which needs suitable mathematical models to be described. Therefore, with full consideration of existing single component mathematical algorithm combining with the characteristics of intestinal absorption and metabolism, we explored and designed a new mathematical algorithm of intestinal absorption and metabolism of multicomponent drug. Then we put forward a new coefficient, P (influence), the relative change rate of the single component's intestinal absorption and metabolism under multicomponent environment compared with single component environment, which described the influences of intestinal absorption and metabolism of the component under multicomponent environment. Moreover, P (influence) highlights the distinctive characteristics of multicomponent drug's intestinal absorption and metabolism, and lays the foundation for the construction of CMMBCS.

Objective To investigate the prognosis of patients with Kawasaki's disease complicated with coronary artery lesion and to provide evidence for diagnosis and treatment of these patients. Methods This study was conducted during January 2002 to June 2007. All patients diagnosed as Kawasaki's disease complicated with coronary artery lesions were from the Affiliated Hospital of Guilin Medical College, the Second People's Hospital of Guangxi Province and Guilin Women and Childrens' Hospital. All cases were echocardiogram examined in month 3, 6, 12, 24 and 36 in the purpose of observing the morphology of coronary artery. The study subjects were re-categorized to the groups of mild, moderate dilatation of coronary artery and giant coronary aneurysm, based on the severity of coronary artery lesion. The results of these results of the three groups were compared. Results Eighty-four cases in the mild group, 27 cases in the moderate group and 8 cases in the giant coronary aneurysm. The recovery cases were 23 (27%), 3 (11%) and 0 in the 3 groups respectively at month 3. The above numbers were 44 (52%), 8 (30%) and 0 respectively at month 6.The numbers were 69(82%), 13 (48%) and 1 (13%) at month 12. The numbers were 78 (93%), 19 (70%), 3 (38%) at month 24. The numbers were 82(98%), 20(74%) and 4(50%) at month 36. Thirteen patients were treated with adenosine-triphosphate (ATP) stress echocardiography examiantion, 5 patients were evaluated by coronary angiography,and 4 patients were tested by 64-slice CT coronary reconstruction. Part of the patients were found to have coronary stenosis or occlusion. Conclusion Patients of Kawasaki's disease often have concurrent coronary artery lesions. Patients with mild dilatation of the coronary artery are the most commonly seen and have the best prognosis. On the contrast, patients with giant coronary aneurysm are the lest common situation and is the worst in prognosis. Part of them will develop coronary artery stenosis or occlusion in late stage which may lead to ischemic heart disease. We should stress on close follow-up of patients with Kawasaki's disease complicated with coronary artery lesion. Appropriate and timely treatment will increase their clinical outcomes.

BACKGROUND: Fatty acid translocase/CD36 (FAT/CD36) in skeletal muscle has been proved to induce skeletal muscle contraction transport to the outer membrane stimulated by movement, which increases FAT/CD36 content in cellular membrane, further leading to more fatty acids into skeletal muscle cells. OBJECTIVE: To observe the effects of Glycyrrhiza Flavone administration before exercise on the pathological changes of quadriceps and FAT/CD36 in rats. METHODS: Thirty male Sprague-Dawley rats were randomly divided into quiet, exercise and combination groups. The rats in the combination group were administrated with 10 mL/(kg?d) Glycyrrhiza Flavone, while the other two groups were given the same volume of normal saline. The rats in the exercise and combination groups were subjected to 6-week training, 19.3 m/minute at the treadmill slope of 5°. The pathological changes of quadriceps were observed by hematoxylin-eosin staining, and the expression level of FAT/CD36 was detected by immunohistochemistry and Western blot assay. RESULTS AND CONCLUSION: Under light microscope, swollen, ruptured and necrotic muscle fibers in the quadriceps were found in the excise group. In the combination group, muscle fibers tightly arranged in the quadriceps with complete edge, which had no significant difference compared with the quiet group. Immunohistochemistry showed that the expression level of FAT/CD36 in the exercise group was significantly higher than that in the quiet group (P < 0.05); the expression level of FAT/CD36 in the combination group was slightly higher than that in the quiet group, but significnatly lower than that in the exercise group (P < 0.05), all above findings were consistent with the western blot assay. Our results indicate that exercise can induce fatty acid transport and accumulation. Due to the synergistic action of Glycyrrhiza Flavonoids, FAT/CD36 increases the efficiency of fatty acid transport, thereby maintaining lipid metabolism balance in the skeletal muscle, which avoids lipid metabolic disorders.

AIM: To evaluate the safety and efficacy of intravitreal bevacizumab ( avastin ) injection in patients with exudative age related macular degeneration ( AMD) .
METHODS: The records of patients treated with intravitreal injection of 1. 75mg bevacizumab for AMD were retrospectively reviewed. All patients were evaluated by complete ophthalmic examination, optical coherence tomography and fundus fluorescein and/or indocyanine green angiography. Observation was made on the best corrected visual acuity ( BCVA) , intraocular pressure, and the changes of lens, vitreous, central retinal thickness (CFT) and total macular volume (TMV), at 1d, 3d, 7d, 1mo and 6mo after the treatment and then compared with those of pre - operation. Repeated treatment with intravitreous bevacizumab occurred if there were signs of persistent or recurrent exudation. And all cases were followed up at least 6mo. An intravitreal injection of bevacizumab (1. 75mg) was given once every 6wk.
RESULTS:All 50 eyes of 48 patients with the average of 58±20. 46 years old were included. The mean baseline of BCVA and CFT were 0. 82±0. 53, and 364. 97±151. 83μm respectively. Although there was no significant decrease in mean CFT and TMV one week after the injection, the mean BCVA had significant improvement. At the last visit of 9. 7mo follow - up, BCVA, CRT and TMV showed significant improvements over baseline values. BCVA was improved by at least two lines in 32 eyes (64%),remained stabilization in 18 eyes (36%) at the last visit. A total of 98 injections were performed and the average number of injections was 1. 98 for each eye in the group. About 50%of re - injections gained at least two lines of vision improvement one week postoperatively. There were no serious adverse events during the treatment.
CONCLUSION: Intravitreal bevacizumab ( avastin ) injection for managing CNV due to age-related macular degeneration is safe and few side effects. Intravitreal avastin associated with improvement in visual acuity ( VA ) , which can reduce macular edema and choroidal neovascularization leakage. But a prolonged treatment effect needs further observation.

BACKGROUND: This study aimed to investigate the epidemiological and clinical characteristics of patients with heat-related il ness, and guide the prevention, diagnosis and treatment of heat-related il ness. METHODS: From June 2013 to August 2013, seventy patients with heat-related illness were treated at Jinshan Hospital of Fudan University, and their epidemiological characteristics, laboratory results, treatment and prognosis were retrospectively analyzed. RESULTS: In the 70 patients, 18 patients suffered from heat stroke and 52 patients from non-heat stroke. When the environmnent temperature was above 35 °C, the body temperature of the patients began to increase markedly. The patients with heat stroke were significantly older than those with non-heat stroke (P<0.05). The body temperature, heart rate, blood glucose, blood lactate dehydrogenase and blood creatine kinase in the patients with heat stroke were higher than those in the patients with non-heat stroke (P<0.05). Blood lactate dehydrogenase and blood creatine kinase were positively correlated with body temperature (r=0.801). CONCLUSION: When the environmental temperature goes above 35 °C, heat-related illness should be prevented, especially in the elderly. The body temperature, heart rate, blood glucose, blood lactate dehydrogenase and blood creatine kinase in patients with heat stroke are higher than those in patients with non-heat stroke. Blood lactate dehydrogenase and blood creatine kinase are positively correlated with body temperature, but their relationship with heat-related illness awaits further study.

Immunophenotype is critical for diagnosing common B-cell acute lymphoblastic leukemia (common ALL) and detecting minimal residual disease. We developed a protocol to explore the immunophenotypic profiles of common ALL based on the expression levels of the antigens associated with B lymphoid development, including IL-7Rα (CD127), cytoplasmic CD79a (cCD79a), CD19, VpreB (CD179a), and sIgM, which are successive and essential for progression of B cells along their developmental pathway. Analysis of the immunophenotypes of 48 common ALL cases showed that the immunophenotypic patterns were highly heterogeneous, with the leukemic cell population differing from case to case. Through the comprehensive analysis of immunophenotypic patterns, the profiles of patient-specific composite leukemia cell populations could provide detailed information helpful for the diagnosis, therapeutic monitoring, and individualized therapies for common ALL.

OBJECTIVETo investigate the effects of surgical treatment and prognosis of aneurysmal bone cyst (ABC) in mobile spine.
METHODSA total of 12 patients with ABC were operated on from 1996 to 2006, and the clinical data were retrospectively reviewed. The patients included 7 male and 5 female, aged from 16 to 52 years (mean, 29 years). Surgical interventions were selected according to WBB criteria. Seven patients underwent total spondylectomy, four underwent resection of posterior arch, one patient received sagittal resection only. Anti-poster or post-lateral approach reconstruction with bone-graft or bone cement and transpedicular screws fixation were performed in the cases. Eight cases received radiotherapy after the operation.
RESULTSThe mean operation blood lose was 3210 ml. The patients were followed-up for 10 to 116 months (mean, 41.8 months). Seven patients got complete recover of spinal cord function, 4 patients experienced local recurrence in 1-2 years post operation. One patient died of multiple metastasis of chondrosarcoma after radiotherapy.
CONCLUSIONSABC in spine is an aggressive disease with high local recurrence rate. Enbloc if possible provides the best result, with excellent prognosis. Radiotherapy should be selected carefully.
