Objective To analyzes the CT manifestations of pulmonary Langerhans cell histiocytosis (PLCH). Methods CT features of 11 patients with PLCH proved pathologically were analyzed retrospectively. Results The main findings in 11 PLCHs were cysts and nodules. Two cases only had cysts,and 1 only had nodules, which most had cavitations. The other 8 cases showed cysts and nodules with 4 cases mainly manifested with cysts and nine mainly manifested with nodules. Two cases had pulmonary interstitial changes. One case only had cysts in the left upper lung field and 10 cases had lesions not only in the upper and middle but in the lower lung field, which 2 cases had more lesions in the lower and costophrenic angle field and 8 cases had less lesions in the costo-phrenic angle field. Three of these 8 cases had more lesions in the superior lobe and apical segment of lower lobe. Conclusion CT manifestations of PLCH are helpful for the early diagnosis.

0.05). Conclusions There was markedly immunoresponsiveness unbalance in acute phase of IM.The large number of mononuclear cells consisted mainly of activated CD8 + T cells.The decrease of CD4 +CD 25 + regulator T cells might be involved in pathogenesis of IM,which provided one of the new ways to treat EBV-associated diseases.

Objective To investigate the clinical application value of the laparoscopic intraoperative cholan-giography in laparoscopic cholecystectomy,and summarize the experience.Methods The clinical data of 169 cases of laparoscopic cholecystectomy intraoperative cholangiography were analyzed retrospectively.Results 169 patients were successfully completed,131 cases recovered well and no complications occurred after operation.29 patients showed hyperamylasemia,of which 3 patients had intractable hyperamylasemia,8 patients complicated with secondary acute pancreatitis,with fasting,gastrointestinal decompression,enzyme inhibition(plus somatostatin)and acid,analgesic, anti infection,rehydration treatment after remission.Conclusion Laparoscopic cholecystectomy intraoperative cholan-giography is a safe and reliable diagnostic technique,on the occurrence of biliary residual stones in prevention of post-operative prevention and timely detection of bile duct injury during operation and improves the success rate of repair of bile duct injury has important clinical value;control adaptation of intraoperative cholangiography has important clinical significance of reasonable application license.

Objective To discuss the intensive gastric cavitary lavage method in treatment of stress ulcer bleeding(SUB).Methods The therapeutic effects of 100 patients with severe SUB in intensive care unit (ICU)from July 2005 to February 2008 treated with intensive gastric cavity lavage method were observed and analyzed.Results In these 100 cases,the bleeding was stopped successfully in 97 cases,the therapeutic effective rate being 97%;there were 17 cases died of complicated pulmonary infection(17%)and 3 cases of bleeding(3%),the total fatality rate being 20%.All the other cases were cured.Conclusion Intensive gastrointestinal lavage therapy is an effective method as acid inhibitor for treatment of SUB,but it can decrease the inhabitant flora in the stomach to pass through gastric-pulmonary route,thus the incidence of pulmonary infection was reduced.

Sodium houttuyfonate (SH) is a derivative of effective component of a Chinese material medica, Houttuynia cordata, which is applied in anti-infection of microorganism. But, the antimicrobial mechanisms of SH still remain unclear. Here, we firstly discovered that SH effectively inhibits the three types of virulence related motility of.Pseudomonas aeruginosa, i.e., swimming, twitching and swarming. The plate assay results showed that the inhibitory action of SH against swimming and twitching in 24 h and swarming in 48 h is dose-dependent; and bacteria nearly lost all of the motile activities under the concentration of 1 x minimum inhibitory concentration (MIC) (512 mg x L(-1) same as azithromycin positive group (1 x MIC, 16 mg x L(-1)). Furthermore, we found that the expression of structural gene flgB and pilG is down-regulated by SH, which implies that inhibitory mechanism of SH against motility of P. aeruginosa may be due to the inhibition of flagella and pili bioformation of P. aeruginosa by SR Therefore, our presented results firstly demonstrate that SH effectively inhibits the motility activities of P. aeruginosa, and suggest that SH could be a promising antipseudomonas agents in clinic.

Objective To investigate the feasibility and safety of retroperitoneal laparoendoscopic single-site (LESS) donor nephrectomy using home-made single-port device.Methods From January 2011 to June 2012,11 consecutive LESS left donor nephrectomies using home-made single-port device with conventional laparoscopic instrument were performed through retroperitoneal access in our center.Results The procedures were completed and no complications occurred in all donors.Mean operative time was 149.5 min.Estimated blood loss was 30-350 ml.Warm ischemia time was 2-4 min.The urine output was prompt in all cases.Recipient graft function was normal within 2 weeks.Donor hospital stay was 5-6 days after operation.Conclusion LESS donor nephrectomy using home-made single-port device in our initial experience is feasible and safe.It is also cost-effective and minimally invasive with conventional laparoscopic donor nephrectomy.This technique is a good option for living donor nephrectomy.

Objective To analyze the clinical and CT manifestations of lung involvement of microscopic polyangiitis (MPA). Methods The clinical manifestations,laboratory ANCA examinations and CT features of 16 patients with lung involvement of MPA were retrospectively reviewed. Results (1) Clinical manifestations: 11 cases had hemoptysis or bloody sputum. Eight cases, who first presented with lung symptoms, were misdiagnosed with other lung diseases. All cases had mulfiorgans injuries involved kidney, cardiovascular and endocrine system, etc. (2) Laboratory examinations: all cases were pANCA positive and 14 cases were MPO-ANCA positive. (3) CT examinations: all cases had interstitial changes, 15 cases were interstitial predominately and 1 case was parenchymal predominately. Eight cases had pulmonary interstitial fibrosis and 11 cases had consolidation and 6 of them had both interstitial and consolidation. Two case had accompanied multiple nodulesand one of them had multiple cavitates. Six cases had mediastinal lymphoadenopathy. Conclusions Most of MPA patients have clinical manifestations of hemoptysis and bloody sputum, the CT examination show interstitial lung disease. Middle or advanced age population presented with above-mentioned manifestations should be alert to MPA, whether or not they have kidney and other organs injury.
