Objective To investigate the relation between serum leptin/tumor necrosis factor-α (TNF-α)and malnutrition in patients with chronic obstructive pulmonary disease (COPD) and stable chronic cor pulmonale (CCP) at high altitude. Methods Totally 162 COPD and CCP patients and 40 normal controls (group C) were studied. COPD and CCP patients were divided into malnutrition group (group A, n = 104) and normal nutrition group (group B, n =58) according to the nutritional parameters. Levels of serum leptin and TNF-α were measured by enzyme-linked immunosorbent assay (ELISA). Results Body mass index (BMI), percentage of normal body weight (NW%), triceps skinfold thickness (TSF), mid-upper arm circumference (MAC), serum albumin (ALB) ingroupA[(17.4±1.8) kg/m2, (82.3±4.3)%, (7.0±2.6) mm, (17.8±2.8) cm, (30.3±3.9)g/L, respectively] were significantly lower than those in group B and group C [(21.8 ± 2.0) kg/m2,(98.6±5.5)%, (9.3±2.6) mm, (21.5±2.9) cm, (36.2±3.8) g/L, and (23.1±2.3) kg/m2,(102.2±5.2)%, (9.7±3.8) mm, (22.1±2.8) cm, (36.8±3.9) g/L, respectively; all P＜0. 01].The levels of serum leptin and TNF-α in group A [(9.5 ±1. 8) ng/ml and (17.3 ±2. 2) ng/ml, respectively]were significantly higher than those in group A and group C [(7.3 ± 2. 0) ng/ml, (13.5 ± 2. 3) ng/ml; and (6. 7 ±2. 3) ng/ml, (12. 8 ±2. 1) ng/ml, respectively; all P ＜0.01). However, they were not significantly different between group A and group B (all P ＞ 0. 05). The level of leptin was negatively correlated with BMI (r=-0.745, P=0. 0005), NW% (r= -0.887, P=0. 0005), TSF (r= -0.725, P=0. 0005), MAC (r= -0. 761, P=0. 0005), serum albumin (r= -0. 558, P=0. 0005) in group A, and was positively correlated with TNF-α (r = 0. 527, P = 0. 0005). Conclusion Serum leptin and TNF-α correlate with malnutrition in patients with COPD and CCP at high altitude.

As a treatment method for advanced hepatic alveolar echinococcosis (AE),liver transplantation has been gradually performed.One patient with hepatic AE recurrence after liver transplantation was admitted to the Fourth Hospital of PLA in November 2012.The patients received liver transplantation in 2006 for the treatment of hepatic AE.Recurrent lesions were found in the head of the pancreas and the right lung.The patient was also associated with liver dysfunction.Liver function was improved obviously after liver-protective treatment,and continuous albendazole treatment was giving to the patient.Based on a full discussion of the patient,we thought that hepatic AE patients who met the following conditions could receive liver transplantation:(1) Severe hepatic insufficiency.(2) Inability to receive radical liver resection.(3) Absence of extra-hepatic metastasis of AE.Albendazole should be administered for at least 2 years after liver transplantation,and the patient should be monitored for a minimum of 10 years for the prevention of possible recurrence of AE.

Objective: To explore the relationship between plasma level of B-type natriuretic peptide (BNP) and short term prognosis in patients of sudden cardiac arrest with successful cardiopulmonary resuscitation (CPR). Methods:A total of 60 relevant patients were divided into 3 groups based on their plasma levels of BNP. Group A, the patients with plasma level of BNP < 200 pg/ml at immediately, 3 hours and 12-24 hours after CPR,n=16. Group B, the patients with consistently increased BNP and at 3 hours, 12-24 hours after CPR and the BNP level > 200 pg/ml , n=22. Group C, the patients with obviously increased BNP at 3 hours after CPR, while at 12-24 hours after CPR, BNP level decreased to lower than 3 hours level,n=22. All patients were followed-up for 6 months to compare the mortality incidence among different groups. Results: There was no patient died in Group A, the mortality incidence in Group B was 11 and in Group C was 3. The 6 months survival rate in Group A was higher than that in Group B (χ2 = 11.337,P=0.001), the survival rates were similar between Group A and Group C (χ2 = 2.330,P=0.127), and the survival rate in Group B was lower than that in Group C (χ2=7.435,P= 0.006). Conclusion: Consistently increased plasma level of BNP may imply heart failure in patients of sudden cardiac arrest with successful CPR, those patients could have poor short term prognosis. It is critical to improve the cardiac function and increase the important organ infusion to make better recent clinical prognosis.
