Objective To investigate the clinicopathological characteristics and surgical treatment of intrathoracic Castleman disease(CD). Methods Clinical data of 14 cases pathologically diagnosed as CD as analysed retrospectively. There were 6 males and 8 females, with an average age of 29 years(17-58). All were undergone surgical resection or biopsy. Among the 12 patients who had unicentric CD, 11 were performed open thoracotomy and lymphadenectomy with posterolateral or sternum approach, and one was treated by video assisted mini thoracotomy(VAMT). For the diagnosis of multicentric CD, one of the 2 patients had video assisted thoracic surgery(VATS) and wedge resection of the lung, and the other had video mediastinoscopy. Results No patient died perioperatively. All were successfully restored except two complications. One had dyspnea in the second postoperative day, as a result of the softening and collapse of bronchial wall in the entrance of the right main bronchus, which revealed by bedside fiberoptic bronchoscopy. One who had lymphadenopathy in the aortopulmonary window suffered from transient hoarseness after surgery. They recovered after symptomatic treatment finally. Regarding pathological classification, there were 11 cases of hyaline vascular type, 2 cases of plasma cell type and 1 case of mixed cellularity type. 13 cases were followed up for 8-110 months and longterm survive was achieved. No recurrence was observed in the 11 cases with unicentric CD and no relapse was occurred in the 2 cases with multicentric CD. Conclusion Both freezing pathology during operation and paraffin pathology postoperation are important for establishing the diagnosis. For unicentric CD, the clinical symptoms are significantly alleviated and it can be universally cured after operation. Multicentric CD needs multiple therapies after the diagnostic procedure and close follow-up.

ObjectiveTo study the value of hepatitis B virus surface antigen (HBsAg) in the evaluation of antiviral efficacy and its influencing factors under a complex population background resulting from various nationalities in Xinjiang. MethodsWe retrospectively analyzed patients with chronic hepatitis B (CHB) admitted and administrated with nucleot(s)ide analogues (NAs) for the first time in Traditional Chinese Medical Hospital of Xinjiang Uygur Autonomous Region from January 2012 to August 2013. The biological, virological, and serological responses were analyzed as well as the possible factors related to HBsAg levels and its reduction levels. ResultsThere were 63 CHB patients enrolled. After 48 weeks' treatment, all patients achieved biological response, and 59 of them achieved complete virological response in spite of 4 patients with partial response. In all the 30 hepatitis B virus e antigen (HBeAg) positive patients, 5 achieved HBeAg seroconversion. After correlation and regression analysis, it turned out that the history (P=0.033) and HBeAg levels at week 48 (P<0.001) were independent impact factors for HBsAg level at week 48. And the reduction degree of HBsAg at week 48 was influenced by HBsAg at week 48. In 21 patients counting to week 72 maintaining biological response, 18 achieved complete virological response. Unfortunately, all 8 HBeAg positive patients encountered no HBeAg loss or seroconversion. After correlation and regression analysis, it turned out that HBsAg level at week 72 was influenced by HBsAg at week 48 (r=0.700, P<0.001). And the decline degree of HBsAg at week 72 was related to baseline HBsAg level. ConclusionSatisfactory efficacy can be achieved via NAs treatment in CHB patients. But when HBsAg is used separately as an indicator for therapeutic efficacy, we should be aware that intrahepatic covalently closed circular DNA (cccDNA) is not only the impact factor of HBsAg variation, the history, the variations of HBeAg and HBsAg itself during the treatment should also be considered.
Objective To evaluate the clinical efficacy and safety of endovascular therapy for spontaneous isolated superior mesenteric artery dissection (SISMAD). Methods The clinical data of 17 patients with SISMAD, who were treated at author's hospital during the period from March 2009 to May 2016, were retrospectively analyzed. According to the Sakamoto angiographic classification, patients were divided into typeⅠ (n=3), typeⅡ (n=5), and type Ⅲ (n=9). Three patients with type Ⅰ were treated with conservative treatment first, and then 2 were treated with endovascular therapy as the poor reaction. The other patients were treated with endovascular treatment right a way. Results Conservative treatment was success in 1 case, 16 patients were treated with endovascular treatment, the technical success rate was 100%, one stent was used in 11 patients and two stents were used in 5 patients, and the blood in the true lumen of superior mesenteric artery (SMA) restored, no major complications occurred. Seventeen patients were followed-up for 3-36 months (mean of 19 months) and the followed-up rate was 100%, no abdominal pain occurred in 17 cases, CTA showed that no dissecting aneurysm was observed and the stents were patent of SMA. Conclusion Interventional therapy is a safe and effective method for SISMAD.
ObjectiveTo evaluate the effectiveness of Othofix pertrochanteric fixator for fixation of intertrochanteric fracture. MethodA retrospective analysis was made on the clinical data from 36 cases of intertrochanteric fracture treated with Othofix pertrochanteric fixator (OPF group) and 47 cases treated with Gamma nail (Gamma group) between October 2012 and March 2015. There was no significant difference in gender, age, cause of injury, side, AO fracture classification, combined medical disease, and injury to operation time between 2 groups (P>0.05) . The operation time, intraoperative blood loss, hospitalization time, fracture union time, and complication rate were recorded and compared between 2 groups. Hip function was evaluated with Sanders post-trauma criteria. ResultsThe operation time, intraoperative blood loss, and hospitalization time of the OPF group were significantly less than those of the Gamma group (P<0.05) . All the cases were followed up 6-12 months (mean, 8.8 months) in 2 groups. Healing of incision by first intention was obtained. Bone union was achieved in 2 groups, and the fracture union time of the OPF group was significantly shorter than that of the Gamma group (t=14.780, P=0.000) . There was no deep wound or pin track infection in 2 groups. Superficial skin reactions developed around the screw and the pins in 14 cases (38.9%) of the OPF group, but no incision infection in the Gamma group, showing significant difference (χ2=22.010, P=0.001) . Mild varus of the hip and pin cutting-out occurred in 3 cases (8.3%) and 2 cases (5.6%) of the OPF group, and in 4 cases (8.5%) and 3 cases (6.4%) of Gamma group, showing no significant difference (χ2=0.001, P=0.960; χ2=0.025, P=0.830) . According to Sanders post-trauma criteria, the results were excellent in 16 cases, good in 15 cases, fair in 3 cases, and poor in 2 cases, with an excellent and good rate of 86.1% in the OPF group; the results were excellent in 22 cases, good in 20 cases, fair in 4 cases, and poor in 1 case, with an excellent and good rate of 89.4% in the Gamma group; and there was no significant difference (χ2=0.200, P=0.610) . ConclusionsThe Othofix pertrochanteric fixator has good effectiveness in the treatment of intertrochanteric fracture, which has the advantages of simple operation, less operation time, little bleeding, and early functional recovery.
ObjectiveTo investigate clinical characteristics and surgical treatment of patients with non-malignant esophageal-tracheal/bronchial fistula.?Methods?We retrospectively analyzed clinical data of 12 patients with non-malignant esophageal-tracheal/bronchial fistula who underwent surgical repair in Peking Union Medical College Hospital from January 2002 to October 2011. There were 6 males and 6 females with a mean age of 49.8 years (ranging from 32 to 72 years). There were 7 patients with esophagotracheal fistula，1 patient with esophagobronchial fistula，2 patients with gastro-bronchial fistula after esophagectomy for esophageal cancer，and 2 patients with esophageal diverticulum bronchial fistula. Nine patients underwent surgical repair via right thoracotomy approach，and 3 patients via left thoracotomy approach. Seven patients underwent esophageal fistula and tracheal fistula repair，1 patient underwent esophageal fistula and bronchial fistula repair，2 patients underwent gastric fistula and bronchial fistula repair，1 patient underwent esophagectomy, gastroesophageal anastomosis and left lower lobectomy, and 1 patient underwent esophageal diverticulum repair and left lower lobectomy.?Results?All the patients recovered well from surgery with no perioperative complication or in-hospital death，and resumed oral intake 7-10 days after surgery. Three months to 1 year postoperatively, regular examinations including upper gastroenterography and fibrobronchoscopy found no sign of tracheal/bronchial stenosis or esophageal stenosis，and no patients needed stent implantation or dilatation treatment. All the patients were followed up from 3 months to 10 years and had a good quality of life during follow-up.?Conclusion?Excluding malignant etiology and determining the exact fistula location are key points of clinical diagnosis for esophageal-tracheal/bronchial fistula. Adequate preoperative nutritional support and 1-stage surgical repair can lead to satisfactory clinical outcomes.
