World Science and Technology-Modernization of Traditional Chinese Medicine 2013;(3):617-619
Professor Zhang Yonghong thinks that the deficiency of lung qi always exists in advanced lung cancer cases. Pathogen infection, phlegm and blood stasis are key factors to the occurrence and development of lung cancer. Clinical treatment in advanced lung cancer should emphasize on the benefiting of qi and supplementing the lung as well as reducing phlegm, removing blood stasis and disintoxication. Attention should be paid to both syndrome differentiation and disease differentiation with the combination of strengthening the body resistance and eliminating evil factors according to different stages of lung cancer.

Objective To investigate the clinical manifestation,pathogenesis and imaging features of hemichorea associated with hyperglycemia in primary diabetes mellitus(DM).Methods Analyze the clinical manifestations,the neuroimaging features and the treatment of the three patients with hemichorea induced by hyperglycaemia in primary DM,and review the literatures about this disease.Results All of the three cases had a long history of uncontrolled diabetes,among whom,two were non-ketotic hyperglycemic patients and one was ketotic hyperglycemic patient.All of them had an acute onset hemichorea which was almost continuous during awakeness and ceased during sleep.The early CT findings in this disorder were high density in the caudate nucleus,putamen and/or globus pallidus on the side contralateral to the involved limbs,but showed decreased attenuation or completely resolved in about a month.T1-weighted MR images in all cases showed high-signal intensities without edema or mass effect in the diseased region which decreased after several months,while the T2-weighted images were more variable.Conclusion Hemichorea induced by hyperglycemia often happens in the patients with poorly controlled DM,and both of the non-ketotic hyperglycemic and the ketotic hyperglycemic state can be the cause.In the major affected region-corpora striata,CT shows hyperdense lesions,T1-weighted MR images show hyperintense lesions and T2-weighted images show variable lesions in the early time.

Objective To probe the surgical approach and effect on upper abdominal malignant tumor infiltrating pancrea. Methods Thirty patients with upper abdominal malignant tumor infiltrating pancreas or tissue around pancrea were treated by radical resection on primary tumor combined pancreaticoduodenectomy. Results Three patients died in 1 month after operation due to multiple organ failure. The patients with gallbladder cancer and metastatic lymph nodes fixed behind caput pancreatis were followed up averaged 35 months. The patients with gastric antrum carcinoma infiltrating caput pancreatis were followed up averaged 31 months. The patients with recurrent gastric cancer infiltrating caput pancreatis were followed up averaged 13 months. The patients with pancreatic and duodenal invasion by cancer of hepatic flexure of colon were followed up averaged 41 months. The patients with hilar cholangiocarcinoma and metastatic lymph nodes fixed behind caput pancreatis were followed up averaged 11 months. Conclusion The patients with upper abdominal malignant tumor infiltrating pancreas should be operated by radical resection on primary tumor combined pancreaticoduodenectomy, which can increase the rate of tumor resection, and be expected to prolong the survival period.

Objective To study the relationship between Tei index and the myocardial enzymes in newborns with myocardial damage due to asphyxia. Methods Forty-four newborns with mild asphyxia,27 newborns with severe asphyxia and 20 healthy newborns hospitalized in our hospital from January 2005 to December 2008 were enrolled in this study.The peak E and peak A and E/A ratio at mitral valve,the ejection fraction,isovolumetric contraction time,isovolumetric relaxation time and Tei index were measured by conventional echocardiography,and aspartate aminotransferase,creatine kinase,lactate dehydrogenase,hydroxybutyrate dehydrogenase and creatine phosphate kinase isoenzyme,and cardiac troponin T were tested also.One-way ANOVA was used to analyze the difference between groups. Results Tei index,isovolumetric contraction time and isovolumetric relaxation time in the severe asphyxia newborns were 0.62±0.13,(47±7)ms and(52±8)ms,higher than those in the mild asphyxia newborns[0.51±0.14,(41±6)ms and(43±6)ms],those in the mild asphyxia newborns were higher than in the healthy newborns[0.39±0.12,(34±6)ms and (37±6)ms] (all P<0.01).Aspartate aminotransferase,lactate dehydrogenase,hydroxybutyrate dehydrogenase,creatine kinase and its isoenzymes and cardiac troponin T in the severe asphyxia newborns were higher than in the mild asphyxia newborns and healthy group(P<0.01).Tei index,isovolumetric contraction time and isovolumetric relaxation time were positively related to the myocardial enzymes.The positive relationships were more statistically significant in Tel index,creatine kinase,its isoenzymes and cardiac troponin T(r=0.762,0.821,0.778,P<0.01).Conclusions Combination of Tei index and myocardial enzymes can not only be applied to assess the cardiac function in newborns with myocardial damage due to asphyxia,but also to evaluate the degree of cardiac dysfunction accurately and dynamically.
