Autologous blood patch pleurodesis (ABPP) was first proposed in 1987. Now it is mainly used to treat intractable pneumothorax and persistent air leakage after pneumonectomy, and also used to treat pneumothorax in children and other rare secondary pneumothorax. Persistent air leakage and pneumothorax of various causes are essentially alveolar pleural fistula. It can usually be treated by closed thoracic drainage, continuous negative pressure suction and surgery. Pleurodesis is a safe and effective alternative to surgery for patients who have failed conventional conservative treatment and can not receive operations. Compared with other pleurodesis adhesives, autologous blood (ABPP) is safer and more effective, and it is simple, painless, cheap and easy to be accepted by patients. But in the domestic and foreign researches in recent years, many details of ABPP treatment have not been standardized. For further research and popularization of ABPP, this article reviews the detailed regulations, efficacy and safety of this technology.

Objective To investigate the expression of aquaporin-1（AQP-1） on pleura in rats with carrageenan-induced pleural effusion and explore the role of AQP-1 in effusion formation.Methods Fifty-six healthy Wistar rats were randomly divided into a normal control group and 6 pleuritis groups（6，12，24，36，48 and 72 h groups respectively）.The rat model of inflammatory pleurisy was induced by injecting l-Carrageenan into the pleural cavity.The expression of AQP-1 on pleura was detected with immunohistochemistry.The mRNA and protein expression of AQP-1 on visceral pleura and parietal pleura were measured by RT-PCR and Western blot assay respectively.The volume of pleural effusions were measured.Results The volume of pleural effusion was 2.10±0.22，4.10±0.15，4.40±0.36，3.20±0.27，2.60±0.18，0.12±0.02 mL in the 6，12，24，36，48 and 72 h pleuritis groups respectively.AQP-1 were mainly expressed on visceral and parietal pleural mesothelial cells and capillary endothelial cells，and significantly increased in all pleuritic rats The mRNA and protein expression of AQP-1 on parietal pleura increased after 6 h and reached peak level at 24 h in pleuritic groups.The mRNA and protein expression of AQP-1 on visceral pleura increased after 12 h and reached peak level at 24 h in pleuritic groups.The expression of AQP-1 on parietal pleura at 12 h and 24 h in pleuritic groups was correlated positively with the volume of pleural effusion（r=0.857，r=0.846，all Plt;0.01）.The expression of AQP-1 on visceral pleura at 24 h in pleuritic groups was positively correlated with the volume of pleural effusion（r=0.725，Plt;0.05）.Conclusion The expression of AQP-1 on pleura were increased in rats with e carrageenan-induced pleural effusion.AQP-1 may play a role in pleural fluid transportation in pleural effusion.
ObjectiveTo compare the influence of intrathoracic and retrosternal esophagogastric anastomosis on pulmonary function in aged patients after esophagectomy. MethodsForty patients (older than 62 years) with upper or middle thoracic esophageal carcinoma (EC) who underwent esophagectomy in Fengtian Hospital of Shenyang Medical College between February 2009 and May 2011 were enrolled in this study. According to different surgical approach, all the patients were divided into an intrathoracic esophagogastric anastomosis (IEGA) group and a retrosternal esophagogastric anastomosis (REGA) group. There were 20 patients in IEGA group including 16 males and 4 females with their age of 62-79 (64.70±11.47) years, who received cervical anastomosis after EC resection and intrathoracic gastric tube reconstruction. There were 20 patients in REGA group including 17 males and 3 females with their age of 63-77 (65.90±12.72) years, who received cervical anastomosis after EC resection and retrosternal gastric tube reconstruction. Pulmonary function test (PFT) was performed preoperatively and on the 15th and 30th postoperative day, and compared between the 2 groups. ResultsThere was no statistical difference in preoperative PFT between the 2 groups (P > 0.05). PFT of IEGA group on the 15th and 30th postoperative day was significantly worse than preoperative PFT (P < 0.05). PFT of REGA group on the 15th and 30th postoperative day was not statistically different from preoperative PFT (P > 0.05). PFT of REGA group on the 15th and 30th postoperative day was significantly better than PFT of IEGA group (P < 0.05). In IEGA group, postoperative complications included anastomotic leak in 1 patient, anastomotic stenosis in 1 patient, pneumonia in 5 patients and atelectasis in 1 patient. In REGA group, postoperative complications included anastomotic leak in 1 patient, anastomotic stenosis in 1 patient, gastric outlet obstruction in 1 patient and pneumonia in 3 patients. All the patients were followed up for 1 year. There was no statistical difference between PFT at 1 year after discharge and PFT on the 30th postoperative day in either group. ConclusionsIEGA can significantly reduce postoperative PFT. REGA has less negative influence on postoperative PFT, is suitable for aged patients and patients with unsatisfactory preoperative PFT, can reduce postoperative complications and improve postoperative quality of life.
ObjectiveTo investigate the diagnostic value of internal medicine thoracoscope combined with pleural GeneXpert MTB/RIF for tuberculous pleurisy.MethodsEighty patients with tuberculous pleurisy admitted to hospital with pleural effusion were treated as tuberculous pleurisy group, and 20 patients with clinical diagnosis of malignant pleural effusion were used as control group. After admission to the hospital, the pre-operative examination of internal medicine thoracoscope were analyzed. All patients were extracted pleural effusion with thoracic puncture in order to send pleural tuberculosis smear and culture. Patients who had no contraindications were arranged internal medicine thoracoscope to get pleural effusion which will be sent to GeneXpert MTB/RIF and pathological tissue biopsy.ResultsIn the tuberculous pleurisy group, nine patients were positive in pleural tuberculous smear, and the positive rate was 11.3%; 4 patients were positive in pleural tuberculous culture, and the positive rate was 5.0%; 75 patients were diagnosed with pathological biopsy, and the positive rate was 93.8%; 69 patients were positive with pleural GeneXpert MTB/RIF, and the positive rate was 86.3%. The positive rate of internal medicine thoracoscopic pleural biopsy combined with pleural GeneXpert MTB/RIF could reached 96.3%. The pleural GeneXpert MTB/RIF lifampin resistance gene was positive in 5 patients, 4 of them were positive for tuberculosis culture, and the drug sensitivity results showed rifampicin resistance. In the control group, patients had negative result in pleural effusion tuberculosis smear, tuberculosis culture and the pleural GeneXpert MTB/RIF.ConclusionsThe diagnosis of tuberculous pleurisy by the combination of internal medicine thoracoscope and pleural GeneXpert MTB/RIF has high specificity and sensitivity. The diagnosis of tuberculous pleurisy by the combination of internal medicine thoracoscope and pleural GeneXpert MTB/RIF has high specificity and sensitivity, which has the value of rapid and accurate diagnosis and early guidance of anti-tuberculosis chemotherapy based on the early judgment of whether rifampin resistance exists.
ObjectiveTo investigate the overall accuracy of interleukin-12 (IL-12) for diagnosis of tuberculous pleurisy. MethodsWe searched in PubMed, Embase, Web of Science, China National Knowledge Infrastructure databases, WanFang Data, and VIP Information for qualified studies that reported diagnostic accuracy of IL-12 for tuberculous pleurisy up to February 2014. The methodological quality of each study was evaluated by Quality assessment of diagnostic accuracy studies. Statistical analyses were performed by Meta-Disc 1.4 software and the pooled sensitivity, specificity and other diagnostic indexes. Meta-analysis of the reported accuracy of each study and summary receiver operating characteristic (SROC) curve were also performed. ResultsEight studies met the inclusion criteria for the analysis. The summary estimates for IL-12 in the diagnosis of tuberculous pleurisy were:sensitivity 0.80 [95% CI (0.76, 0.84)], specificity 0.76 [95% CI (0.71, 0.81)], positive likelihood ratio 3.23 [95% CI (2.26, 4.60)], negative likelihood ratio 0.30 [95% CI (0.20, 0.45)], diagnostic odds ratio 13.57 [95% CI (6.66, 27.64)], and the area under the curve of SROC was 0.86. ConclusionIL-12 plays a valuable role in the diagnosis of tuberculous pleurisy, and IL-12 may be a useful diagnostic marker for tuberculous pleurisy.
