Objective To classify the segmental bronchial patterns of the left upper lobe by combining three post-processing images from 64 slice spiral CT and to study how to identify different ramifications in transverse thin-section CT.Methods Totally 204 patients with routine thorax scans were enrolled.The segmental bronchi were demonstrated in terms of bronchial tree,virtual bronchoscopy and thin-section CT three post-processing images.Integrated with the three post-processing images,the segmental bronchial patterns of the left upper lobar bronchi were classified into several main types,and displayed in transverse thin-section CT.Results The segmental bronchial ramifications of the left upper lobe were classified into three types mainly:common stem of apical and posterior segmental bronchi(64%,130/200),trifurcation(23%,45/200),common stem of apical and anterior segmental bronchi(10%,21/200),and they could be identified in two typical slices of transverse thin-section CT.There were two dominating types in the left basilar segmental bronchi:bifurcation(75%,163/216),trifurcation(18%,39/216),and they could also be identified in two typical slices of transverse thin-section CT.Conclusion The segmental bronchi of the left lung can be definitely classified by three post-processing images from 64 slice spiral CT.

Objective To classify the segmental bronchial patterns of the right upper lobe by combining bronchial tree and CT virtual bronchoscopy(CTVE)post-processing techniques from 64-slice spiral CT.Methods Two hundred and four patients with routine thorax scans were enrolled.The segmental bronchi were demonstrated in terms of bronchial tree and CTVE.First,we checked how many patients can be classified with any one of the above post-processing approaches.Then,integrating the two methods,we classified the fight upper segmental bronchial patterns of the 204 patients.At last,the patterns of the right upper bronchus were analyzed.Results bronchial tree post-processing images were stereoscopic and intuitive.It could be used to identify common stem of bifurcation easily,however,it was hard to be used to differentiate short common stem of bifurcation from trifurcation.CTVE demonstrated segmental bronchi from inside of lumen,and can readily show the short common stem of bifurcation and trifurcation of bronchi.Combining two post-processing techniques,the segmental bronchial ramification of the right upper lobe was mainly classified in three types:trifurcation in 76 patients(37.3%),common stem of apical and posterior segmental bronchi in 50 patients(24.5%)and others in 78 patients(38.2%).Conclusion The combination of multiple post-processing of 64-slice CT posses great superiority to classify the pattern of the right upper lobe bronchi.

Objective To evaluate the plasma amino acid level alteration and determine amino acid loss in patients with abdominal inflammation and acute renal failure during continuous veno-venous hemofiltration (CVVH). Methods Ten patients with abdominal infection and acute renal failure were admitted to the Nanjing General Hospital of Nanjing Military Command of PLA from September 2008 to September 2009. CVVH was performed with AV600S polysulfone hemofilter for 24 hours. Samples of plasma amino acid were obtained before,at 12 and 24 hours after the beginning of CVVH. High pressure liquid chromatography was used to detect amino acid concentrations in plasma and replacement fluid. All data were analyzed using t test or Wilcoxon rank sum test. Results Of the ten patients, three died of septic shock and three died of multi-organ dysfunction syndrome.The level of plasma amino acids decreased significantly after CVVH, and the levels of histidine, isoleucine, cysteine and glutamine decreased from (22.1 ±10.3), (20.0 ±7.6), (10.3±4.7), (122.3 ±72.2)μmol/L to (5.6 ±3.4), ( 6.4 ± 2.5 ), ( 2.9 ± 2.4 ), (42.5 ± 33.6) μ mol/L. The total plasma amino acid levels significantly reduced by 52% at 12 hours after the beginning of CVVH and by 59% at 24 hours after the beginning of CVVH.The mean amino acid loss was (9631± 1089)mg/d. The mean losses of essential and non-essential amino acids were ( 5072 ± 618 ) mg/d and ( 3747 ± 654 ) mg/d, respectively, with a significant difference ( t = 4. 52,P ＜0.05 ). There was a positive correlation between individual amino acid loss and the plasma concentrations of respective amino acids at 12 hours after the beginning of CVVH ( r = 0. 68, P ＜ 0.05 ). Conclusions Plasma amino acid would be cleared through hemofilter during CVVH in patients with abdominal inflammation and acuterenal failure. As a result, it is necessary to take account of the ultrafiltrate amino acid loss when setting nutritional schedule, especially increasing the non-essential amino acid content of total parenteral nutrition.

Objective To investigate the incidence of diseases in member of rescue teams in the Wenchuan earthquake in Sichuan Province.Method Twenty days afer the Wenchuan earthquake in 2008,5 068 resucing staff of rescue learns as random and cluster sample were investigated and analyzed to find the factors impacting their fitness associated with their characters,diseases,work,and encampment styles.Results Members of rescue teams suffered from the following diseases:insect dermatitis (18.37%),tinea pedis (10.83%),acute upper respiratory infection (10.56%)and solar dermatitis (6.20%).Contrasted by work tasks,staff resucing on the front line had the highest incidence of acute upper-respiratory infection(11.04%) ,logistics workers had the highest incidence of tinea pedis(15.21% ),and more patients of acute gastroenteritis,insect dermatitis,gingivitis emerged from medical personnel group(P<0.05).The encampment sites were devided into three sorts:plain land,hillside and valley.The staff stayed at valley had higher incidence of acute upper respiratory infection (24.90%),insect dermatitis (36.50%) and tinca pedis (20.02%)than those worked at plain land and hillside (P<0.01).The incidence of acute gastroerrteritis(1.26%) ha staff resides hillside is lower than that in valley or plain land (P<0.05).Conclusions In the period of rescue actions in the guake-hit region,the members of rescue teams suffered from famihar diseases such as dermatitis and acute upper-respiratory infection,etc.The incidence of diseases is associated with their work tasks and the topography of cantonment.

Objective:To observe the protective effect of deproteinized extract of calf blood (DECB)on the ethanol-induced liver injury of the mice,and to preliminaryly discuss its mechanism. Methods:Sixty healthy ICR mice were divided into control group,model group,positive drug group,low,medium and high doses of DECB groups (n=10).By intragastric administration,the mice in control group were given 20 mL·kg-1 saline solution, the mice in low,medium and high doses of DECB groups were administrated with 0.125,0.250,0.500 g·kg -1 DECB,and the mice in positive drug group were administrated with 0.63 g·kg -1 Hugan Tablets;once a day for 30 d. 1 h after the last administration,except control group,the mice in other groups were administrated with one-time grant of 50% ethanol 14 mL·kg -1 ,and fasted for 16 h to establish the models of acute alcohol liver injury.The endurance alcohol time and drunk time of the mice were determined,the activities of aspartate aminotransferase (ALT)and alanine transaminase (AST)activity in serum of the mice were detected,the levels of triglyceride (TG),glutathione (GSH)and malonic dialdehyde (MDA)in liver tissue were determined,and the pathological changes of liver tissue were detected.Results:Compared with model group,the drunk symptoms of the mice in different doses of DECB groups were obviously reduced,the endurance time of the mice in high dose of DECB group and positive drug group was prolonged (P <0.05),and the drinking time was shortened (P <0.05);the ALT and AST activities in serum in mediun and high doses of DECB groups were significantly lower than those in model group (P <0.05).Compared with model group,the MDA and TG levels in liver tissue of the mice in medium and high doses of DECB groups and positive drug group were obviously reduced,and the GSH levels were increased (P <0.05);compared with model group,the pathological damages of liver tissue of the mice in high dose of DECB group caused by ethanol were significantly reduced.Conclusion:DECB can improve ethanol-induced liver injury which may be related to the inhibition of hepatic oxidative stress response.

BACKGROUND: Vitiligo is a common acquired pigmentary disease caused by destruction of epidermal melanocytes in underlying autoimmune response. Few studies have been focused on the role of chemokines in non-segmental vitiligo (NSV) concomitant with autoimmune thyroid disease (AITD) and alopecia areata (AA). OBJECTIVE: The aim of this study was to determine the best serum biomarker for predictive role in the progression of vitiligo and to evaluate the influence of AA and/or AITD on vitiligo by using the biomarker. METHODS: This prospective cohort study recruited 45 NSV patients: 14 without either AITD or AA, 12 with AITD, 11 with AA, and 8 with both AITD and AA. Serum levels of CXCL1, CXCL8, CXCL9, CXCL10, CXCL12, CXCL13, and CXCL16 were analyzed by ELISA. CXCR3 mRNA expression was detected on PBMCs by RT-PCR. Improvement was evaluated using repigmentation scales. RESULTS: Serum CXCL10 levels, along with the expression of CXCR3 mRNA were higher in NSV patients with AITD or AA alone than in those without AITD or AA. Moreover, serum CXCL10 levels, along with the expression of CXCR3 mRNA were higher in NSV patients with both AITD and AA than in those with AITD or AA alone. Poorer repigmentation was observed in NSV patients with both AA and AITD than in those with AA or AITD alone. CONCLUSION: CXCL10 could be a biomarker to predict the progression of NSV. Dermatologists should pay much attention to those NSV patients concomitant with AITD and/or AA, for comorbidity might lead to more active autoimmune reaction.
