OBJECTIVE To discuss the diagnosis and treatment of Burkholderia cepacia(BCE) pneumonia. METHODS The 31 cases of inpatients and outpatients in our hospital were analyzed from Jul 2005 to Dec 2007. RESULTS From them 11 cases were with community-acquired pneumonia and 20 cases with hospital-acquired pneumonia,the underlying diseases in 27 cases.Of these cases,19 cases were kidney transplant recipients,four cases with chronic obstructive pulmonary disease,seven cases with non-insulin dependent diabetes,three cases with cerebral vascular diseases,and two cases were with malignant tumors.All cases were diagnosed by bronchoscopy,bronchial lavage,and BCE positive in douche liquid.At last there were 24(77.4%) cases cured,2 cases discharged(6.5%) and 5 cases deceased(16.1%). CONCLUSIONS BCE is a multi-drug resistant bacteria.BCE pneumonia often appears severe.It appears non-specific clinical symptoms in early stage and higher mortality.It should be treated as soon as possible by using piperacillin /tazobactam-based combined anti-infection treatment.

Objective To validate the repeatability of the simplified cough score and its responsiveness to effective treatment and investigate the relationship between the simplified cough score and cough symptom score.MethodsA total of 119 patients with chronic cough referred to our respiratory clinic were recruited into the study between June 2010 and February 2011. Cough severity was evaluated by the simplified cough score,cough symptom score,Leicester cough questionnaire,and cough reflex sensitivity detection,and the correlations among them were analyzed.The change ratio,effect size,and standardized response mean of the simplified cough score were calculated after a 2-week course of effective treatment.The repeatability of the simplified cough score was assessed in 99 untreated patients with stable chronic cough.ResultsThe intraclass correlation coefficient in a 3-day test-retest interval of simplified cough score was 0.90 ( 95 ％ CI =0.84 - 0.92,P =0.00 ) for daytime and 0.89 ( 95 ％ CI =0.91 - 0.96,P =0.00 ) for nighttime. There was an obvious positive linear correlation between the simplified cough score and cough symptom score ( daytime:r =0.82,P =0.00 ; nighttime:r =0.92,P =0.00 ),a significant negative linear correlation between the cough score and Leicester cough questionnaire,and a weak but significant negative correlation between the simplified cough score and cough threshold C2 or C5 to capsaicin. After a 2-week course of effective treatment,the change ratio,effect size,and standardized response mean were 46.71％,1.16,and 1.05 for daytime and 71.87％,1.09,and 1.10 for nighttime,respectively.ConclusionThe simplified cough score is a reliable and valid tool for evaluation of cough severity in clinical practice.

Objective To investigate the inhibitory effect of carbon-coated iron nanoparticles carrying cisplatin on the growth of NCI-H446 lung cancer cells and expressions of Caspase 3 and Survivin mRNA.Methods NCI-H446 lung cancer cells were treated with iron-carbon nanoparticles and/or cisplatin.The cell viability was detected by MTT method,and the mRNA expressions of Caspase 3 and Survivin were measured with RT-PCR.Results Cisplatin could inhibit the growth of NCI-H446 lung cancer cells,and the inhibitory effect was stronger when it was combined with the iron-carbon nanoparticles.The cells had apoptosis.The mRNA expression of Caspase 3 of NCI-H446 lung cancer cells was remarkably enhanced after treatment with iron-carbon nanoparticles combined with cisplatin,while the mRNA expression of Survivin was notably weakened (P＜0.05).Conclusion Carbon-coated iron nanoparticles carrying cisplatin could significantly increase the chemotherapy sensitivity of cisplatin on NCI-H446 lung cancer cells and enhance the therapeutic efficacy of chemotherapy drugs.

Objective:To analyze the sleep quality before treatment and related risk factors of sleep disorder in patients with nasopharyngeal carcinoma (NPC). Methods: Totally 143 patients first diagnosed as nasopharyngeal carcinoma were selected [ average age (43 ± 10) years, 100 males and 43 females] in a NPC ward of one hospital, the Chinese version of Pittsburgh Sleep Quality Index (PSQI, total score ＞ 5 diagnosed as sleep disorder) was used to investigate the sleep quality before treatment, and the logistic regression analysis was used to analyze related factors of the sleep disorder before treatment Results: The rate of sleep disorder was 50.3％. The logistic regression analysis showed that age was a risk factor of sleep disorder before treatment in patients with NPC (OR = 1.04, 95％ CI: 1.01-1.08), while gender, culture degree, clinical stage, body mass index were not correlated with sleep disorder (Ps＞0.05). Conclusion: It suggests that patients with NPC may have a higher incidence of sleep disorder before treatment, and older patients may be more prone to pre-treatment sleep disorder.

OBJECTIVETo investigate the complications in intra-operative radiotherapy (IORT) for patients with local advanced pancreatic cancer.

METHODSThe clinical data, operation material, overall dose of IORT, postoperative therapy, complications, treatment and prognosis were retrospectively analyzed in all the in-hospital pancreatic cancer patients from Nov 2008 to Jan 2012.

RESULTSThere were 115 patients with local advanced pancreatic cancer treated with IORT in this study. 81 cases had a tumor in the head of pancreas and 34 cases in the pancreatic body and tail. The operation method was IORT combined with internal drainage surgery. The intra-operative radiotherapy was performed using Mobetron mobile electron accelerator, with a total dose of 12-20 Gy. Bilioenteric anastomosis and/or gastrointestinal anastomosis were included in the internal drainage surgery. Gastroparesis syndrome (10.4%), hemorrhage (3.5%), abdominal infection (2.6%), pancreatic fistula (0.9%) and renal failure (1.7%) were the common postoperative complication of IORT. All patients were cured except one who died of digestive tract hemorrhage.

CONCLUSIONSMajor complications of IORT are gastroparesis syndrome, abdominal infection and hemorrhage. The incidence of gastroparesis syndrome is at the top of the list. However, early complications have a relatively better prognosis, indicating that IORT is a safe and reliable therapy for patients with locally advanced pancreatic cancer.

Objective To investigate the value of Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity(POSSUM)and a modification of the POSSUM system(P?P0SSUM) scoring system in predicting the surgical operative risk of pancreaticoduodenectomy for periampullary tumors. Methods POSSUM and P?POSSUM scoring systems were used to retrospectively evaluate the clinical data of 432 patients with periampullar tumors who underwent pancreaticoduodenectomy in the Department of Abdominal Surgery, Cancer Hospital,ChineseAcademy of Medical Sciences from January 1985 to December 2010. The predictive occurrence of postoperative complications and mortality rate were calculated according to the formula. ROC curve analysis and different group of risk factors were used to determine the discrimination ability of the two score systems, and to determine their predictive efficacy by comparing the actual and predictive complications and mortality rates, using Hosmer?Lemeshow test to determine the goodness of fit of the two scoring systems. Results The average physiological score of the 432 patients was 16.1±3.5, and the average surgical severity scorewas 19.6±2.7. ROC curve analysis showed that the area under ROC curve for mortality predicted by POSSUM and P?POSSUM were 0.893 and 0.888, showing a non?significant difference ( P>0. 05 ) between them. The area under ROC curve for operative complications predicted by POSSUM scoring system was 0. 575. The POSSUM score system was most accurate for the prediction of complication rates of 20%?40%, showing the O/E value of 0.81. Compared with the POSSUM score system, P?POSSUM had better ability in the prediction of postoperative mortality, when the predicted value of mortality was greater than 15%, the predictive result was more accurate, and the O/E value was 1.00. Conclusions POSSUM and P?POSSUM scoring system have good value in predicting the mortality of patients with periampullary tumors undergoing pancreaticoduodenectomy, but a poorer value of POSSUM score system in prediction of complications. We can establish a more suitable scoring system for pancreaticoduodenectomy by modifying the score constant and weight, to better predict surgical risk and reduce the operative complications and mortality.

Objective To explore the learning curve for middle pancreatectomy by comparing the outcomes of middle pancreatectomy operated by a single treatment group at different stages. Methods A total of 48 patients received middle pancreatectomy by single treatment group between January 2006 and April 2014 at our hospital. These 48 cases were divided into 10 stages ( 5 cases in each) according to the operation sequence. The operation time, blood loss, surgical complications, rate of negative margin and postoperative hospital stay were analyzed retrospectively. Results There was no significant difference among the 10 stages in respect to surgical complications, rate of negative margin and postoperative hospital stay ( P>0.05) . The median operation time and blood loss in the first stage was 375 min and 530 ml, respectively. The median operation time and blood loss in the second stage was 280 min and 330 ml, respectively. There were significant differences between these two stages and the other later stages in median operation time and blood loss ( P<0.01) . However, there was no significant difference among the stages 3 to 10 in the median operation time and blood loss ( P>0.05 for all) . Conclusion After 10?15 cases of middle pancreatectomy, a surgeon can be skilled and experienced in this surgical procedure with few surgical complications.
