Objective To investigate the clinical features and treatment ofBrucellosis disease in children in recent years.Methods The clinical data of 24 children withBrucellosis disease admitted during January 2011 to December 2015 were retrospectively analyzed.Results In 24 children, 18 was male and 6 was female and average age was 9.8±3.13 years (4-14 years). Twenty-four children were diagnosed withBrucellosis disease by positive tiger red plate agglutination tests and their antibody titer was 1:800-1:100. The children lived mainly in the pastoral areas; four cases (16.67%) had sick family members and cattle and sheep; three cases (12.5%) had histoty of contact only with sick family members; 12 cases (50.00%) had cattle and sheep exposure history; 3 cases (12.5%) had raised cattle or sheep at home in the past 2 years; 2 cases (8.33%) had not have clear transmission route. The onset of the disease occurred year round, with the highest incidence in June and July. The common clinical symptoms were fever, arthralgia, weak, sweat, and anorexia, combined with hepatomegaly and splenomegaly. Patients younger than 8 years old were treated with rifampin and sulfamethoxazole. Patients equal to or older than 8 years old were treated with doxycycline and rifampin. Twenty-three children had been cured after treatment. Only one child stopped taking the drugs 3 weeks after discharge, which resulted in recurrence.Conclusion For children living in pasturing area suffered with unexplained recurrent fever, brucellosis disease should be considered and ruled out.

ObjectiveTo describe the modified (narrowed) gastric tube and two methods on the establishmentof enteral feeding pathway in esophagectomy.MethodsFrom July 2003 to April 2006,we made traditional gastric tube for patients underwent esophagectomy to substitute the dissected esophagus while from May 2006 to November 2009,we made modified gastric tube for the same purpose.From July 2003 to November 2009,enteral nutrition tubes for all these patients are placed intraoperatively by two different ways,which made early post-operative nutrition support possible for these patients.ResultsNo perioperative death occurred among the patients.The length of the modified gastric tube ensured the anastomosis by circular stapler at the apex thorax or in the bases of cervical region.No statistical differences were found between the two group in terms of survival rate.The intraoperative establishment of enteral nutrition pathway ensured the early enteral nutrition support after the operation.ConclusionThe utility of the modified gastric tube extends the length of gastric tube to make mechanical anastomose easier and safer; meanwhile,the intraoperative establishment of enteral nutrition pathway ensures the early enteral nutrition support after the operation.

BACKGROUND: Bronchopleural fistula (BPF) is one of the most serious and rare postoperative complications, especially the bronchial stump fistula after lobectomy/pneumonectomy. Common treatment options include conservative medical treatment combined with surgery. However, due to the delayed healing of the fistula, the chest cavity continues to communicate with the outside world, and the patient is prone to complicated with severe thoracic infection and respiratory failure, so that the physical condition can hardly tolerate the second surgical procedure. Endoscopic treatment provides a new option for the treatment of this complication. METHODS: A case of right pulmonary squamous cell carcinoma was admitted to the Department of Thoracic Surgery II, Peking University Cancer Hospital in June 2016. The diagnosis and treatment was retrospectively analyzed, and the literature was reviewed. RESULTS: A 65 year old male patient was admitted to hospital because of "cough with blood in sputum for 3 months". Chest computed tomography (CT) showed soft tissue density mass shadow in the right lower lobe. A tumor could be seen in the opening of the right middle lobe and basal segment of lower lobe. Biopsy confirmed squamous cell carcinoma. Diagnosis consideration: squamous cell carcinoma of the middle and lower lobe of the right lung (cT2aN2, IIIa). Patients received gemcitabine plus cisplatin neoadjuvant chemotherapy for 2 cycles, and the effect of chemotherapy showed stable disease (SD). Four weeks after chemotherapy, the patient underwent video-assisted thoracic surgery (VATS) assisted right middle and lower lobectomy and mediastinal lymph node dissection. On the 5th day after operation, the patient developed acute respiratory distress syndrome (ARDS) and was transferred to intensive care unit (ICU) again after endotracheal intubation. On the 7th day after operation, the patient developed a right intermediate trunk bronchial stump fistula, but due to ARDS, the patient's physical condition could not tolerate the second operation. Under the support of extracorporeal membrane oxygenation (ECMO), a membrane covered, expandable, hinged stent was inserted into the intermediate trunk bronchial stump through rigid bronchoscope, and was successfully blocked. Due to no improvement in ARDS and irreversible pulmonary interstitial fibrosis, the patient received double lung transplantation successfully after systemic anti-infection treatment. CONCLUSIONS Endoscopic implantation of covered stent is a simple, safe and effective method for closure of bronchial stump fistula. When the patient's clinical situation is not suitable for immediate surgery, endoscopic stent implantation can be used as a preferred treatment method to create opportunities for follow-up treatment.

BACKGROUND: MiR-148b-3p is an important microRNA that has been reported to be significantly related to various types of cancer, but its role in lung adenocarcinoma remains elusive. The purpose of this study is to detect the expression level of miR-148b-3p in lung adenocarcinoma specimens, and to analyze its correlation with the clinicopathological features as well as the prognosis of patients with lung adenocarcinoma. METHODS: A total of 123 tumor specimens from lung adenocarcinoma patients who underwent surgical resection in our department from January 2011 to December 2012 were collected. The expression of miR-148b-3p was detected by quantitative real-time PCR (qRT-PCR), and its correlation with clinicopathological features of patients with lung adenocarcinoma was analyzed. Multivariate Cox proportional hazard models were used to analyze independent predictors of overall survival in patients with lung adenocarcinoma. The overall survival (OS) of patients in miR-148b-3p high expression group and miR-148b-3p low expression group were estimated by means of the Kaplan-Meier method and were compared using the Log-rank test method. RESULTS: Of the 123 patients with lung adenocarcinoma, 71 were in miR-148b-3p high expression group and 52 in low expression group. MiR-148b-3p was significantly associated with tumor grade (P=0.001) and tumor size (P=0.007), but not with age, gender, smoking history, history of alcohol, tumor thrombus, pleural invasion, node status or metastasis status. Multivariate Cox proportional hazard model analysis showed that tumor size (P=0.032), node status (P=0.005) and miR-148b-3p expression level (P=0.047) were significant independent predictors of overall survival of patients with lung adenocarcinoma. Kaplan-Meier survival analysis showed that the overall survival of patients with high expression of miR-148b-3p was significantly better than that of patients with low expression (P=0.010). CONCLUSIONS MiR-148b-3p was significantly associated with tumor grade and tumor size in lung adenocarcinoma, and served as an independent predictor of overall survival of patients with lung adenocarcinoma. The overall survival of patients with high expression level of miR-148b-3p was significantly better than that of patients with low expression.

Objective    To evaluate the prognosis of different node status on the basis of the eighth TNM classification for lung cancer. Methods    We retrospectively reviewed the clinical data of 1 851 non-small cell lung cancer (NSCLC) patients who underwent radical resection between January 2005 and December 2014. There were 1 078 males and 773 females at age of 16–86 (59.7±9.7) years. Survival probability was estimated by the Kaplan-Meier method and significance was assessed by the log-rank test. Results    This cohort study was consisted of 1 209 patients with N0, 305 with N1 and 337 with N2. N0 patients were divided into a N0a group and a N0b group according to whether the 13 and 14 level of lymph nodes were examined. The survival rate of the N0a group was significantly higher than that of the N0b group, and the 5-year survival rate was 88.9% and 81.3% (P<0.001), respectively. According to the number of lymph node metastasis stations, N1 was divided into a N1a (single) group and a N1b (multiple) group. And no significant difference was observed between the two groups in survival rate (P=0.562). Based on the presence of lymph nodes of 10–12 level, N1 was divided into a negative group and a positive group. And the negative group was found with significantly higher survival rate than the positive group (5-year survival rate of 78.4% vs. 64.3%, P=0.007). The N2 patients were divided into a single station metastasis group (a N2a1 group), a single station with N1 positive group (a N2a2 group) and a multiple station group (a N2b group), and the percentage was accounted for 22.0% (74/337), 37.7% (127/337) and 40.3% (136/337), respectively. There was a statistical difference in 5-year survival rate (62.2% vs. 56.5% vs. 37.3%) among the three groups (P=0.001). Conclusion    Subgroup analysis of N staging in NSCLC patients shows significant survival differences which may be more consistent with multidisciplinary therapy under precise staging patterns.

To investigate whether postoperative therapy can bring survival benefits to patients with locally advanced esophageal squamous cell carcinoma who have received neoadjuvant chemotherapy with TP regimen. Methods     We retrospectively reviewed clinical data of 115 patients with locally advanced esophageal squamous cell carcinoma who received neoadjuvant chemotherapy with TP regimen and underwent esophagectomy in our hospital from January 2007 through December 2016. Patients were divided into two groups including a non-receiving treatment group (54 patients with 47 males and 7 females) and a receiving treatment group (61 patients with 52 males and 9 females). There were 31 patients with postoperative chemotherapy, 14 with postoperative radiotherapy, and 16 with postoperative chemotherapy and radiotherapy in the receiving treatment group. Results     In the non-receiving treatment group, the 5-year median disease free survival (DFS) rate was 54.7%, and the 5-year overall survival (OS) rate was 55.3%. In the receiving treatment group, the median DFS was 46.0 months (95% CI 22.9–69.1), the 5-year DFS rate was 42.3%; and the   median OS was 68.0 months (95% CI 33.0–103.0), the 5-year OS rate was 51.3%. Furthermore, there was no statistical difference between the two groups with regards to DFS (P=0.641) or OS (P=0.757) using Kaplan-Meier method. Besides, in each subgroup, the results of Cox proportional hazard model analysis showed postoperative treatment did not improve survival (P>0.05, respectively). Conclusion     Postoperative treatment does not bring survival benefits to patients with esophageal squamous cell carcinoma who have received neoadjuvant chemotherapy with TP regimen.

Objective     To observe and describe anatomical types of the pulmonary arteries to keep safety of lung resection. Methods     Between November 25, 2005 and January 22, 2013, 194 patients who underwent right upper lobectomy/sleeve lobectomy or combined lung resection including right upper lobectomy were included in Peking University Cancer Hospital. There were 128 males with a median age of 59 (37-86) years and 66 females with a median age of 60 (42-77) years. We separated the pulmonary arteries and recorded the number and positions of them. Some patients were recorded photographically. Results     There were 10 types of right upper lobe pulmonary artery branches in this study. Type 1: 1 apicoanterior segmental artery, 1 ascending segmental artery, 96 patients (49.5%); Type 2: 1 apicoanterior segmental artery, 2 ascending segmental arteries, 48 patients (24.7%); Type 3: 2 apicoanterior segmental arteries, 1 ascending segmental artery, 28 patients (14.4%); Type 4: 2 apicoanterior segmental arteries, 2 ascending segmental arteries, 9 patients (4.6%); Type 5: 1 apicoanterior segmental artery only, 6 patients (3.1%); Type 6: 1 apicoanterior segmental artery, 3 ascending segmental arteries, 3 patients (1.5%); Type 7: 4 apicoanterior segmental arteries, 1 ascending segmental artery, 1 patient (0.5%); Type 8: 3 apicoanterior segmental arteries, 1 ascending segmental artery, 1 patient (0.5%); Type 9: 2 apicoanterior segmental arteries, 1 patient (0.5%); Type 10: 3 apicoanterior segmental arteries, 2 ascending segmental arteries, 1 patient (0.5%). Conclusion     The types of pulmonary artery branches are predictable in some way. It would be helpful to reduce the risk of pulmonary artery injury and improve the operation safety by following   the rules. Variations of pulmonary artery should be noticed to avoid the major bleeding due to the pulmonary artery injury.

BACKGROUND: Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE). METHODS: This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE. RESULTS: This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively. CONCLUSIONS Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.
