Objective:To investigate the relationship of polymorphism of leptin receptor gene Gln223Arg with asthma and metabolic syndrome.Methods: Collected 120 asthma patients,92 metabolic syndrome patients,54 asthma combined metabolic syndrome patients and 81 normal controls.According to the severity,the asthma patients were divided into mild-medium group and severe group.The serum leptin level was measured by ELISA,the genotypes of leptin receptor were analyzed by the method of polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP),and statistcs of each subject′s MBI,blood pressure,lung function and fasting blood glucose were collected.Results: ①There were significant differences in genotype and allele frequency in leptin receptor gene Gln223Arg between the metabolic syndrome group,asthma combined metabolic syndrome group and normal control group(P<0.05).②The allele frequency and genotype in leptin receptor gene Gln223Arg were significant different between the severe asthma group and normal control group(P<0.05).③The serum leptin level,BMI and systolic blood pressure of AA+AG genotype group were significiant higher than GG genotype group(P<0.05),while the value of FEV1% and FEV1/FVC of lung function were lower than GG genotype group(P<0.05).Conclusion: Leptin receptor gene Gln223Arg polymorphism is correlated with asthma and metabolic syndrome,and by causing leptin resistance,the A allele might be the genetic factor that contribute to individual susceptibility for asthma and metabolic syndrome.

Objective To observe and investigate the therapeutic effect of thalidomide on gastrointestinal bleeding of angiodysplasia.Methods Eighteen patients with recurrent gastrointestinal bleeding of angiodysplasia were treated with thalidomide 100 mg daily for 4 months.Median follow-up time was 16.7 months.The changes of clinical setting and serum.vascular endothelial growth factor(VEGF)and tumor necrosis faetor-α(TNF-α)level between pre-therapy and post-therapy were compared.Results The clinical setting of patients in post therapy was significantly better than that in pre-therapy.The overall symptom score,the median bleeding frequency and median transfusion volume of patients after therapy was significantly lower than those before the therapy[(15.000±3.630)vs(5.330±3.325),(11.220±6.404)vs(1.000±1.237),(1422.22±1556.601)ml vs(100.00±240.098)ml,respectively,all P＜0.01],while median hemoglobin was obviously higher than that before the therapy[(5.950±1.656)g/ml vs(9.533±2.278)g/ml,P＜0.01].Serum VEGF and TNF-α levels decreased obviously after the therapy(118 pg/ml vs 58 pg/ml,116 pg/ml vs 34 pg/ml,P＜0.01).Conclusions Thalidomide can suppress the serum VEGF and TNF-α levels of the patients with recurrent gastrointestinal bleeding of angiodysplasia,then play a significantly role in preventing the rebleeding in patients with recurrent gastrointestinal bleeding of angiodysplasia.

To alleviate the shortage of excellent talents of traditional Chinese medicine (TCM), the State Administration of Traditional Chinese Medicine has decided to cultivate a group of talents with strong theoretical foundation, rich practical experience and exquisite skills who would like to devote themselves to TCM technology research. The national talent training program for inheritance of characteristic TCM technology is a major breakthrough in the history of new China in the cultivation of high-level TCM technology talents. A retrospective analysis was performed on the national talent training program for inheritance of characteristic TCM technology hold in training bases from Beijing, Shanghai, Guangdong Province, Jiangsu Province, Anhui Province, Xinjiang Uygur Autonomous Region, Inner Mongolia Autonomous Region, Heilongjiang Province, Yunnan Province, Sichuan Province, Shaanxi Province and Fujian Province. Based on the completion assessment work of 2014 and 2015 national talent training program for inheritance of characteristic TCM technology, and after knowledge exchange and discussion with the training subjects from 30 provinces and some teaching experts in the field of characteristic TCM technology, this paper summarizes the work of the national talent training program for inheritance of characteristic TCM technology. After trained in bases in China, training subjects' theoretical knowledge and practical skills as well as their comprehensive capacity have been greatly promoted. At the same time, there are also some problems and shortages. For example, characteristic TCM technology in some training bases is not prominent enough, some characteristic TCM technologies are not well inherited, and the affiliations of some training subjects do not pay enough attention to it. All of these problems should be solved and improved in future work.

Objective To explore the prognostic value of N-terminal pro-brain natriuretic peptide ( NT-pro-BNP) levels in critically ill infants. Methods Eighty-one critically ill infants were enrolled from January 2013 to January 2014 in pediatric intensive care unit. The minimum of pediatric critical illness score ( PCIS) and the number of dysfunction organs were calculated within 24 hour after admission. According to PCIS,the critically ill infants were divided into extremely critical group(PCIS≤70,n=25),critical group (PCIS 71-80,n=30)and non-critical group(PCIS>80,n=26). According to the prognosis,the critically ill infants were divided into survival group (n=68)and death group(n=13). The serum NT-pro-BNP levels were determined on the first day,third day and convalescent phase. The relationships of serum NT-pro-BNP levels with PCIS and the number of dysfunction organs and prognosis were observed. Results The study showed statistical significances of serum NT-pro-BNP levels among the extremely critical group, critical group and non-critical group,whether on the first day,or on the third day and convalescent phase(P<0. 01). There were statistical significances of serum NT-pro-BNP levels among different stages of the disease in each group(P<0. 01). Compared with survival group,PCIS was significantly lower and the serum NT-pro-BNP levels and the number of dysfunction organs were significantly higher in death group. The serum NT-pro-BNP level on the third day was higher than that on the first day in death group ( P<0. 01 ) , while no significant difference was found in survival group. The serum NT-pro-BNP levels on the first day and the third day and PCIS were negatively correlated(r= -0. 59,P<0. 01;r= -0. 66,P<0. 01). The serum NT-pro-BNP levels on the first day and the third day and the number of dysfunction organs were positively correlated(r=0. 40,P<0. 05;r=0. 57,P<0. 01). Conclusion The serum NT-pro-BNP levels of the critically ill infants are correlated with disease severity,and can be useful for assessing the severity of critical illness.

Pulmonary embolism is the cardiovascular disease caused by endogenous or exogenous emboli blocking the pulmonary artery system. Pulmonary embolism is clinically very common and has a high recurrence rate. Its etiology is complicated. Pulmonary embolism recurrence can be caused by many factors, which affect its prognosis. Complicated diseases, residual thrombosis, anticoagulation therapy and respiratory disorders are the main factors that lead to pulmonary embolism recurrence. Some blood test indicators can also reflect the recurrence of pulmonary embolism. This paper reviews the risk factors and prevention strategies of pulmonary embolism recurrence, with the purpose of reducing recurrence rate, improving prognosis and thereby providing objective evidence for clinical practice.

Objective To explore the correlation between lipoprotein-associated phospholipase A2 (Lp-PLA2) and perioperative myocardial injury (PMI),and to discuss the predictive value of Lp-PLA2 in patients with stable angina after percutaneous coronary intervention (PCI).Methods A total of 222 consecutive patients with stable angina,who were admitted to Yixing Municipal People's Hospital,Jiangsu Province,China to receive PCI during the period from June 2015 to March 2017,were enrolled in this study.The patients' baseline data as well as the distribution pattern of coronary lesions,were recorded.According to the paclitaxel-PCI and the surgical cooperative study (SYNTAX) score,the severity of target vascular lesions was assessed,which was classified into low score group (0 to 22 points),middle score group (23 to 32 points) and high score group (≥33 points).The preoperative blood lipid level and renal function,both preoperative and postoperative Troponin T (cTnT),high sensitive C reactive protein(hs-CRP),as well as the postoperative Lp-PLA2 were tested.Results After the procedure,the Lp-PLA2 levels in patients with normal cTnT value (n=155) and in patients with elevated cTnT value (n=67) were(122.21±43.80) ng/ml and (224.53±65.00) ng/ml respectively (P＜0.05).SYNTAX score analysis showed that low score group had 120 patients,middle score group had 78 patients and high score group had 24 patients,the Lp-PLA2 levels of the above three groups were (119.51±51.96) ng/ml,(178.67±61.49) ng/ml and (233.16±61.32) ng/ml respectively,the differences were statistically significant between each other among the three groups (P＜0.05).Pearson correlation analysis indicated that a parallel correlation existed between Lp-PLA2 levels and postoperative cTnT values (R=0.492,P＜0.05).Logistic regression analysis revealed that Lp-PLA2 was the independent risk factor for elevated cTnT value during the perioperative period of PCI (OR=7.377,95％CI=3.368-16.156,P＜0.05).The area under ROC curve of Lp-PLA2 was 0.896 (95％CI=0.874-0.945,P＜0.001),the best cut-off point was 179 ng/ml,and the sensitivity and specificity for the diagnosis of PMI were 92.2％ and 66.7％,respectively.Conclusion Lp-PLA2 levels are closely correlated with the increased cTnT values after PCI,and the preoperative high level of Lp-PLA2 is the independent risk factor for PMI after PCI.
