1.Daidzein and Genistein produced by a marine Micromonospora carbonacea FIM02-635
Chinese Journal of Marine Drugs 1994;0(01):-
Objective To study the active secondary metabolites from marine microorganism FIM02-635.Methods The producing strain was identified by taxonomical and phylogenetic studies.Two compounds FW635I1 and FW635I2 with immunosuppressive activities were extracted by organic solvents from the culture broth and purified by silica gel column chromatography and high speed counter current chromatography.The structures of the two compounds were determined by physico-chemical properties and spectral analyses,the biological activities were assayed in vitro.Results and Conclusion The producing strain was named as Micromonospora carbonacea FIM 02-635. Two compounds FW635I1 and FW635I2 were determined to be isoflavone Daidzein and Genistein,respectively,showed immunosuppressive and antitumor activities,but not antimicrobial activities.

Objective To investigate the relation of the associated biomarkers and the early clinicaloutcomes in acute cerebral infarction. Methods Three hundred and seventeen patients with cerebral infarctionwere enrolled after the first onset. Coagulation function, liver, kidney function, blood cholesterol, andelectrolytical were tested within 24 hours of onset. Chinese Stroke Scale (CSS) and National Institutes of HealthStroke Scale (NHISS) were scored on admission, and NHISS on the tenth day after admission were scored.Evaluated the severity on admission and early functional recovery on the tenth day after admission with CSS andthe difference of NHISS. According to CSS, patients were divided into three groups: mild, moderate and severegroup. According to scale margin of NHISS between on admission and the tenth day after admission , patients weredivided into three groups: improved group, unchanged group and worsened group. Difference of biomarkers amongdifferent groups were statistical analyzed. Results Serum calcium (SC), TBIL, FIB, HCY, SUA levels amongmild, moderate and severe group were significantly different (P < 0.05). The more severe, the higher TBIL,FIB, HCY, SUA levels and the lower SC level. The SC, FIB, SUA levels were significantly different amongimproved group, unchanged group and worsened group (P < 0.05). SC level were the lowest in worsened group,while FIB, SUA levels were the highest. Conclusions In acute cerebral infarction patients, SC, FIB, SUAlevels are closely related to the severity and early clinical prognosis.

Objective To investigate clinical effects of video assisted thoracoscopic lung volume reduction surgery(LVRS) for severe emphysema. Methods Six patients with severe emphysema underwent lung volume reduction surgery by video assisted thoracoscopy.The LVRS was performed unilateraly in 4 and bilateraly in 2 through median stemination.20%~30% of total volume of lung was resected. Results There was no operative death.All patients were followed up for 3 to 17 months.After LVRS,the mean forced expiratory volume in 1 second(FEV 1) and PaO 2 increased by 24 6% and 8 3%,respectively,Total lung capacity(TLC),residual volume(RV) and ventilatory assistance decreased by 24 6%,20 3% and 47 1% respectively Conclusions LVRS by video-assited thoracoscopy is an effective and safe technique for patients with severe emphysema.It can relieve dyspnea and improve excise tolerance and the quality of life.

Objective To study the risk factors related to early neurological deterioration (END) in patients with recurrent cerebral infarction (RCI). Methods Three hundreds and twenty-six RCI patients admitted to our hospital from January 2014 to March 2015 were divided into END group (n = 66) and non-END group (n =260). The clinical and laboratory data were collected, and their cerebrovascular lesions were accessed according to the angiographic findings. Results (1) Single factor analysis showed the level of cholesterol was significantly higher in the END group than that of the non-END group (P < 0.05). The proportion of patients suffering from smoking, arterial occlusions, early onset stroke associated pneumonia (SAP) and hyponatremia was also higher in the END group (all P < 0.05). (2) Logistic regression analysis showed that arterial occlusions (OR = 2.137, 95%CI 1.093~4.181), SAP (OR=2.001, 95%CI 1.023~3.912) and hyponetremia (OR=2.467, 95%CI 1.217~ 5.000) were independent risk factors for END of RCI patients (all P < 0.05). Conclusion Arterial occlusions, SAP and hyponatremia may be used as predictors of the early development of RCI patients.
