Objective To explore the chest features of patients with the novel influenza type A H1N1 on HRCT. Methods One hundred and seventy-two chest HRCT examinations on 163 cases with Influenza type A H1N1 (9 cases were reexamed) were retrospectively analyzed using standard pulmonary window and mediastinal window, respectively. HRCT imaging appearances were summarized. Results Ninety-seven cases showed normal on chest HRCT, while the others showed abnormalities of parenchymal and interstitial. Among them, HRCT identified ground-glass opacity in 35 cases (53.0%), centrilobular nodules in 30 cases (45.5%), thickening of intralobular septa in 31 cases (47.0%), intralobular thin reticulation and micro-nodule in 8 cases (12.1%), single-lobular inflammation in 19 cases (28.8%), consolidation of lung(the large consolidation and multiple small consolidations)in 15 cases (22.7%), pulmonary atelectasis in 3 cases (4.5%), and irregular lines in 2 cases (3.0%). Pleurisy was also revealed including 8 cases with right pleurisy, 5 cases with left pleurisy, and 19 cases with bilateral pleurisy. Mediastinal and axillary lymphadenopathy were found in 7 cases, who were spared of pleural effusion. All above abnormalities resolved quickly after anti- virus treatment. Conclusion Parenchymal and interstitial abnormalities, mediastinum and axillary fossa lymphadenopathy, and pleural effusion were the common findings on HRCT in patients with Influenza type A H1N1, which were similar to those of other viral pneumonia.

Serum creatinine was determined by enzymatic method.99mTc-GFR was measured by 99mTc-DTPA dynamic renal imaging and considered as GFR marker in 210 males and 180 females with type 2 diabetes,eGFR was calculated by Cockcroft-Gault formula,MDRD equation7,abbreviated MDRD equation,modified MDRD equation for Chinese (c-7GFR4 and c-aGFR4),and CKD-EPI equation.They were analyzed by correlation,regression,Bland-Altman analysis and receiver operating characteristic (ROC) curve analysis.The correlation coefficients for Cockcroft-Gault formula,MDRD equation7,abbreviated MDRD equation,c-7GFR4,c-aGFR4,and CKD-EPI equation were 0.79,0.76,0.77,0.76,0.76,0.81 respectively.And the differences were-14.99,-18.85,-23.79,-25.85,-32.07,and-7.16,respectively.The area under ROC curves were 0.91,0.88,0.89,0.88,0.90,and 0.92,respeetively.Kappa values were 0.67、0.52、0.39、0.49、0.46、0.54respectively.The CKD-EPI equation seams to be the most accurate measurement among the six methods when the serum creatinine was determined by enzymatic method in Chinese type 2 diabetic patients.

ObjectiveTo assess the differential diagnostic value of serum intestinal fatty acid binding protein (I-FABP)in distinguishing intestinal ischemia patients from acute abdomen patients.MethodsA total of 151 patients with acute abdomen and 17 healthy controls from the PLA General Hospital were enrolled from November,2009 to August,2011. Serum I-FABP levels were measured by ELISA.According to the ROC curve,the cut-off value,sensitivity,specificity,positive likelihood ratio (PLR),negative likelihood ratio ( NLR),positive predietive value (PPV) and negative predictive value (NPV) were calculated. ResultsOf the 151 acute abdomen patients,there were 24 intestinal ischemia patients and 127 without intestinal ischemia.Serum I-FABP level in intestinal ischemia group [( 109.67 ±48.82) μg/L]was significantly higher than those in patients without intestinal ischemia [(36.78 ± 11.25) μg/L]and healthy controls[(8.33 ±6.25) μg/L]( all P values ＜0.01 ).The serum I-FABP cut-off value for the diagnosis of intestinal ischemia was 87.52 μg/L.Serum I-FABP was efficient in terms of sensitivity (0.762),NPV(0.963),PLR(3.05) and NLR (0.24) in the diagnosis of intestinal ischemia.ConclusionI-FABP is potentially useful for discriminating intestinal ischemia from acute abdomen.

Objective To study the relationship between MRI features and pathological characteristics of the renal clear cell carcinoma,and to conduct a comparative analysis.Methods 23 patients renal clear cell carcinoma who were proved by postoperative pathology were retrospectively analyzed. The preoperative MRI findings and the postoperative pathological characteristics were compared. Results MRI plain scan showed uniform signal was seen in 2 cases, and mixed signal was found in 21 cases with cystic and necrosis. Blood was seen in 11 cases and false envelope was present in 12 cases. Dynamic enhanced scanning revealed that solid part was enhanced obviously, it was lower than the renal cortex but higher than the renal medulla in cortical phase and continued to be enhanced in medullary phase and delay phase.Postoperative pathological characteristics showed that tumor profiles were yellow-white and cystic and necrotic structures were present within tumors, blood was found in 17 cases. Endoscopic tumor cells were present in solid nests or acinar structure, and mesenchyma was rich in thin-walled vessels involved in reticular interval.14 cases were found to have false envelope.Conclusion Renal clear carcinoma MRI imaging manifestion is related to organixational srructure. MR plain scan combined with dynamic enhanced scan has very high value in the diangnodis of renal cell carcoinoma.

Methods Young plants of E. breviscapus were planted under various color films and light intensities, their biomass and total flavonoid content were determined when plants flowered. Results The biomass and total flavonoid content of individuals under 100% and 80% sunshine were higher than those under 50% sunshine. The biomasses of plants under yellow, red, purple, or blue film were lower than those under white film. Under the blue film, the total flavonoid content of the plant was the highest; while under white film, the total flavonoid yield was the highest. Conclusion Light intensity and light quality significantly affect the growth and total flavonoid accummulation of E. breviscapus. The biomass and total flavonoid yield are the highest when under full sunshine.

Objective To evaluate the effects of facial nerve reconstruction surgery by reviewing the clinical information and follow-up results of 42 cases.Methods The clinical data of 42 patients who were diagnosed as facial schwannoma and received tumor resection and facial nerve reconstruction simultaneously from January 2004 to December 2015 in our department were studied.The surgeries included anastomosis between the two faical nerves(3 cases), facial nerve transplantation(4 cases), Hypoglossal/masseteric-facial nerve anastomosis(27 cases) and cross-facial nerve graft(8 cases).We evaluated the facial nerve function using H-B grade and Fisch score post-operation (1 week, 3 months,6 months and 1 year after surgery).Results The Fisch scores were significantly different between 1 week and 3 months, 3 months and 6 months post-operation for patients received cross-facial nerve graft.The facial nerve function became better as time went by.While there were no difference between 6 months and 1 year post-operation.On the other hand, the scores were significantly different between 6 months and 1 year post-operation for patients received hypoglossal/masseteric facial nerve anastomosis.Conclusion Most patients received tumor section and facial nerve reconstruction simultaneously could gain good results, it took a long time for the facial nerve function to return to a stable state and some of them were still in recovering 1 year after surgery.

Energy expenditure of five young adults worked in the hot desert environment were measured by the methods of indirect calorimetry in the Wuwei Gansou in July 1989.The results indicated that the basal metabolism rate, the resting metabolism rate and the energy cost of young adults marching in the desert and Gobi (15kg load, at rate of 3.5km/h) were 2.782,3.059,14. 188, 10.305 kJ? m-2?min-1 respectively. It was shown that under the similar conditions energy expenditure marching in the desert was 38% more than in the Gobi.Ambient temperature had a greater effect on energy expenditure but the effect was various at different activities. When at 24.5-38.4℃ during marchi-ng(15kg load),1℃increase in ambient temperature was associated with anincrease of about 0.86% energy consumption. While at 25-33℃ during quiet rest the energy consumption tended to decrease with an increase of ambient temperature. But at 33-40℃ it increased with ambient temperature again. It is suggested that the energy metabolism may be more easily influenced by ambient temperature when the metabolic heat production of human body is increased.The present study recommended the estimation of energy requirement for the adult with a moderate activity in hot desert environment should be approximate 15.062MJ/d
