Pulmonary lymphangioleiomyomatosis is a rare disease characterized by the abnormal proliferation of pulmonary lymphatic smooth muscle cells. It is common in women and often accompanied by recurrent pneumothorax, chylothorax and progressive dyspnea, imaging characterized by diffuse cystic lesions in both lungs. Pulmonary lymphangioleiomyomatosis progresses aggressively and has a very poor prognosis, with a lack of effective medical treatment options in the advanced stages. Lung transplantation is a safe and effective method for the treatment of advanced pulmonary lymphangioleiomyomatosis, which may significantly improve the survival rate and quality of life of patients. The median survival period after surgery can reach 12 years. This article reviews the pathogenesis, diagnosis, treatment of pulmonary lymphangioleiomyomatosis, and the current status and existing problems of lung transplantation in pulmonary lymphangioleiomyomatosis, aiming to provide a reference for the clinical treatment and subsequent research of pulmonary lymphangioleiomyomatosis.

Rejection after lung transplantation, including acute rejection (AR) and chronic rejection manifested with chronic lung allograft dysfunction (CLAD), is the main factor affecting the long-term survival of allografts. Exosome, a type of extracellular nanovesicle for intercellular communication among eukaryotic cells, could carry complex biological information and participate in various physiological and pathological processes. Exosome has become a critical immune medium in rejection, regulates the incidence and development of rejection through multiple pathways, and also plays a key role in the monitoring and management of rejection. In this article, the type of rejection after lung transplantation, the mechanism underlying the role of exosome in regulating rejection, exosome acting as biomarkers and the application in rejection treatment were reviewed, aiming to provide a novel direction for comprehensive diagnosis and treatment of rejection following lung transplantation.

Objective To improve the surgical efficacy of bilateral lung transplantation for pediatric cystic fibrosis through multi-disciplinary team (MDT). Methods Preoperative MDT consultation was delivered for a 10-year-old child with rare end-stage cystic fibrosis to establish the corresponding treatment protocol. Results The child was diagnosed with cystic fibrosis for 5 years, and the indication of lung transplantation were confirmed. After preoperative MDT consultation, bilateral lung transplantation via a Clam-shell incision was determined. The vital signs were maintained stable during operation. Postoperatively, ventilator-assisted ventilation, anti-infection, immunosuppression, acid suppression, prevention of stress ulceration and other treatments were delivered. Individualized treatment was given according to the characteristics of the child, and the child was well recovered. Conclusions Through preoperative MDT consultation, lung transplantation yields satisfactory surgical efficacy in treating pediatric cystic fibrosis and lowers the risk of postoperative complications, which deserves application in clinical practice.

Objective To investigate the selection of recipients,operative technique, and perioperative management of lung transplantation.Methods From June 2013 to September 2016, 9 patients with pulmonary lymphangioleiomyomatosis un-derwent lung transplantation at Affiliated Wuxi People's Hospital.There were 9 females aged from 23 to 52 years.Chest en-hancement of CT in 9 patients prior to transplantation suggests multiple different sized thin-walled cystic shadows in whole lung. Nine patients received bilateral sequence lung transplantation ( BSLT) .The pathological findings after the operation indicated that cells of the abnormal proliferation of smooth muscle diffused around the bronchi , vessels and lymphatics , and widened the alveolar septum, which was consistent with the pathological changes in the patients with PLAM .We analyzed the differences of oxygenation index, forcedexpiratory volume at 1 sec(FEV1), and DLCO％ pred.Using paired t test to compare these indica-tors, P<0.05 was considered statistically significant.Results The oxygenation index was increased from(210 ±55) mmHg (1 mmHg=0.133 kPa) to(400 ±80)mmHg after treatment, the difference was statistically significant(P<0.05).The FEV1 was increased from(1.0 ±0.2)L to(2.8 ±0.4)L, and the difference was statistically significant(P<0.05).The DLCO％pred was increased from(27.5 ±2.5)％ to(75.0 ±10.0)％, and the difference was statistically significant(P<0.05).Fi-nally, 8 patients were discharged from the hospital, and the pulmonary function was good.1 patients died of infection and acute rejection on the 13 day after operation.Conclusion Lung transplantation is effective in the treatment of chronic thromboem-bolic pulmonary hypertension , and long-term survival requires further investigations .Lung transplantation is the only effective means for the treatment of end-stage pulmonary lymphangioleiomyomatosis .Bilateral sequence lung transplantation is the first choice.

Cordyceps militaris exopolysaccharides (EPS) have many pharmacological activities such as boosting immunity and antifatigue. To obtain EPS efficiently, we added moderate Vernonia amygdalina leaf powder as inducer to the fermentation medium to promote the production of Cordyceps militaris EPS and studied the infrared absorption spectrum and antioxidant activities of the EPS after optimization. The optimum liquid fermentation conditions were as follows: addition of Vernonia amygdalina leaf powder of 8 g/L, fermentation duration of 9 d, initial pH of 6.5, inoculation quantity of 5.0 mL. Under such a condition, the yield of Cordyceps militaris EPS reached (5.24±0.28) mg/mL, increased by 205.20% compared to the control group without adding Vernonia amygdalina leaf powder. Results of infrared analysis and antioxidant activity showed that the Vernonia amygdalina leaves had little effect on the structure and activities of Cordyceps militaris EPS. The results of this research suggest that Vernonia amygdalina leaf can enhance the production of Cordyceps militaris EPS effectively, and provides a novel method for efficient production of EPS in Cordyceps militaris.

Objective To study the influence of pulmonary artery hypertension (PAH) on survival of patients with advanced chronic obstructive pulmonary disease (COPD) on the waiting list of lung transplantation.Methods The characteristics of 143 patients with COPD receiving lung transplantation evaluation from January 2014 to August 2016 were queried.Mild PAH was defined as mean pulmonary artery pressure (mPAP) ≥25 mmHg and severe ≥35 mrnHg by right heart catheterization measurements.The incidence of PAH was studied,and the patients were divided to different groups to determine the effect of PAH on survival prior to transplantation on the basis of different definitions of PAH.Kaplan Meier method was used to draw survival curves,and a log-rank test was used to analyze the effect of PAH on survival of COPD patients on the waiting list of pulmonary transplantation.Univariate and multivariate Cox proportional hazard models were performed to test the relationship between each main covariate and the hazard of mortality.The waiting time was tracked from wait list entry date until death or censoring,and the censoring issues were as follows:receiving lung transplantation,removing from the waiting list without transplant,and still wating for donor until the last follow-up day (2016-08-30).Results Of 143 COPD patients,there were 119 males and 24 males,with mean age of 61.73 years old;46 patients received lung transplantation,and the remaining 97 not;50 had mPAP ≥25 mmHg and 21 had mPAP ≥35 mmHg.A total of 23 cases (22.88％) died on the waiting list.Thirty-eight patients were removed from the list prior to transplantation,and 36 were still on the waiting list.Kaplan-Meier survival function showed suvival of patients with mild PAH or severe PAH was significantly shorter than that of patients without PAH (P＜0.001).Using Cox proportional hazards models,univariate analysis revealed significant differences in survival for mild PAH (HR =2.147,95％CI 1.429-3.157,P＜ 0.001) and severe PAH (HR =3.458,95 ％ CI 2.518-4.859,P＜0.001).Multivariate Cox models identified significant risk for death for mild PAH (HR=2.518,95％CI 1.728-3.364,P＜0.001) and severePAH HR=4.027,95％ CI 3.257-4.703,P＜0.001).Conclusion The incidence of PAH among COPD patients waiting for lung transplantation was high.PAH is associated with significantly increased risk of death among COPD patients waiting for lung transplantation.

OBJECTIVETo explore the role of eukaryotic translation elongation factor 1A1 (eEF1A1) in regulating the invasion and metastasis of hepatocellular carcinoma (HCC) cells and the possible mechanism.

METHODSqRT-PCR and Western blotting were used to detect the mRNA and protein expression of eEF1A1 and NOB1 in different HCC cell lines and normal liver cells. The invasion and migration abilities of HCC cells with eEF1A1 knockdown or overexpression were examined using Transwell chamber assay and RTCA assay, and the changes in NOB1 mRNA and protein expressions in the cells were detected. The effects of increasing NOB1 expression in HCCLM3-sheEF1A1 cells and decreasing NOB1 expression in eEF1A1-overexpressing MHCC97h cells on eEF1A1 expression and cell invasion and migration abilities were analyzed using Western blotting, Transwell chamber assay and RTCA assay.

RESULTSThe expressions of eEF1A1 and NOB1 were significantly increased in positive correlation in HCC cells as compared with normal hepatocytes. Knockdown of eEF1A1 significantly decreased the invasion and migration of HCC cells and reduced the mRNA and protein expression of NOB1 ( < 0.01). Overexpression of eEF1A1 significantly enhanced invasion and migration of HCC cells and increased NOB1 mRNA and protein expressions ( < 0.01). Increasing NOB1 expression in HCCLM3-sheEF1A1 cells led to the restoration of NOB1 expression and cell invasion and migration abilities ( < 0.01), whereas decreasing NOB1 in MHCC97h-eEF1A1 cells resulted in inhibition of NOB1 expression and cell invasion and migration ( < 0.01).

CONCLUSIONSeEF1A1 positively regulates the expression of NOB1 to promote the invasion and migration of HCC cells .
