METHODSWe retrieved papers of Chinese Journal of Applied Physiology from 2009 to 2013 from CNKI, and performed a statistical analysis of papers information contained in the text using bibliometrics method. Papers information such as document type, found support, author affiliation type, and discipline classification, etc. was analyzed.

RESULTSSeven hundred and forty two papers including 27 full English articles in total were published in Chinese Journal of Applied Physiology from 2009 to 2013. More papers were supported by national, provincial, and the other foundation, it was about 82.6% of all papers.

CONCLUSIONChinese Journal of Applied Physiology has stable manuscript resources, various discipline papers, and play an important role for development of applied physiology in China.

Objective To estimate the frequency of heart valvular involvement in Chinese patients with Takayasu arteritis (TAK) and its correlation with other clinical features. Methods Ninety-one patients with TAK were studied and their clinical manifestations, laboratory test, vascular images and echocardio - gra-phic findings were retrospectively reviewed. The data were compared between patients who had heart valvular involvement and those who had not. Mann-Whitney U-test or Student's t-test, Chi-squared test or Fisher's exact test were used for analysis. Results Aortic regurgitation and mitral regurgitation were both confirmed in 20 (22%) patients. Tricuspid regurgitation and pulmonary valve regurgitation were observed in 10 (11%) and 2 (2%) patients, respectively. Older age at onset, longer disease duration, hypertension and involvement of the ascending aorta were all significantly more frequent in TAK patients with aortic regurgitation (t=2.903, P<0.01; Z=-2.759, P<0.01; χ2=7.918, P<0.01; Z=-4.454, P<0.01) than those without. However, the constitutional symptoms and acute phase reactants [erythrocyte sedimentation rate (ESR) and C reactive protein (CRP)] were not statistically different between patients with and without valvular regurgitation (P>0.05). Aortic valvular pathology examination of the three TAK patients who had underwent aortic valve replacement showed no inflammatory cell infiltration. Conclusion This study has demonstrated that heart valve involvement is common in patients with TAK, mainly in the form of regurgitation, and which may be secondary to hypertension and other cardiovascular complications. We should pay more attention to the screening and treatment of heart valvular involvement in TAK patients.

Molecular methods and fluoroscopic techniques suggest that rich microbial diversity exist in the marine environment, but less than 1% of these microbes can be cultured in the laboratory conditions, and that the cultivable dominant species were even less. This limitation has long been a barrier to the development of environmental microbiology and the utilization of marine resources. In the past decade, novel methods for culture and detection of these uncultured marine microbes have successfully applied to obtain several conventionally-uncultured microbes including those from extreme environments. Those progresses have inspired researchers greatly. Developments in the research of marine microbial resources are an important basis for the study of the micro-world and deserve increasing scientific attention.

Objective: To detect the systolic and diastolic velocity in patients with idiopathic premature ventricular beat(PVB)by pulsed wave-tissue Doppler imaging (PW-TDI) techniques.Methods: There were two groups involved in this study. PVB group,n=30,patients with idiopathic PVB,and Control group,n=30,of healthy subjects. The changes of cardiac function were measured and compared between two groups by the index of myocardial motion velocity using PW-TDI techniques.Results: A total of 7 sites were studied,there were no significant differences in systolic peak velocities (Sm),time velocity integral (TVI),peak velocity of the early relaxation wave (Em),peak velocity of the later relaxation wave (Am) and Em/Am ratio (Em/Am) between the Control group and PVB group in the normal sinus beat (P＞0.05).Compared with the normal sinus beat,Sm,TVI,Em and Em/Am were significantly lower in PVB (P<0.01),while Sm,TVI,Em in the post-PVB sinus beat were significantly higher than that in normal sinus beat (P<0.01). However,there were no significant differences of Am in each site among the normal sinus beat,PVB and the post-PVB sinus beat. Conclusion: PVB and PVB-induced compensational interval could significantly influence the systolic and diastolic function of the ventricle.

Objective To investigate the prevalence of anxiety and depression among the persons with disabilities in Shanghai and the factors related to them. Methods From November to December, 2014, 731 persons with disabilities were consecutively enrolled in this cross-sectional study. They were assessed with Self-rating Anxiety Scale (SAS) and the Self-rating Depression Scale (SDS). Binary Logistic regression analysis was employed to reveal potential related factors of anxiety and depression. Results The prevalence rates of anxiety and depression among the disabled in Shanghai were 9.58%and 8.48%, respectively. The duration (OR=0.967, P<0.05) and severity (OR<1, P<0.05) of disability were associated with depression, whereas retiral (OR=2.047, P<0.05), living alone or in care unit (OR=3.073, P<0.01) and duration of disability (OR=0.956, P<0.01) were associated with anxiety. Conclusion The frequency of anxiety and depression is mild among the persons with disabilities in Shanghai, and a special intervention is needed.

Objective To construct Fas-targeting siRNA-expressing plasmid, and explore the significance of Fas inhibition in the treatment of acute aplastic anemia. Methods U6 promoter cassette and siFas sequence were obtained by PCR method, and cloned into modified pcDNA3.1 to produce plasmid pU6-siFas, which was transfected into P815 cells with limpofectin 2000, and then Fas expression was detected by immunohistochemistry. Results The plasmid pU6-siFas could efficiently reduce the expression of Fas and confer G-418 resistance in P815 cells. Conclusion The successful construction of the siRNA expressing plasmid will facilitate the application of RNA interference technique, and lay foundation for further studies of the therapeutic effect of Fas inhibition on acute aplastic anemia.

Objective The aim of this retrospective study was to analyze the role of surgery in the management of limited-stage-Ⅱ small cell lung cancer.Methods A retrospective review of 82 patients with limited-stage Ⅱ small cell lung cancer between January 2001 and December 2009 was performed.The prognostic impact of different therapy and the clinicopathologic factors were analyzed.Using SPSS 16.0 statistical software for data analysis.Log-rank test for the difference of survivale rate.Using the Cox model for muliti-factor survival analysis.Chi-square test for local recurrence and distant metastasis rate.Results The overall median survival time and the 1-,3-,and 5-year overall survival rates were 27.0 months,62.1％,35.9％,and 21.0％,respectively.Median survival was 34.0 months in surgical patients vs 16.0 months in nonsurgical patients (P =0.000).Median survival after lobectomy or pneumonectomy was significantly longer than after wedge resection (P =0.048).However,survival after wedge resection was still significantly longer than survival in nonsurgical patients(P =0.024).Survival analysis confirmed that the operation,chemotherapy and radiotherapy were showed to be independent prognostic factors.The local-regional recurrencer rates of lobectomy or pneumonectomy group was lower than wedge resection group(P =0.030).The distant metastasis rates of lobectomy or pneumonectomy group was lower than nonsurgical grou (P =0.021).Conclusion This study suggests that lobectomy or pneumonectomy combined with adjuvant radio-chemotherapy should be recommended for patients with limited-stage Ⅱ small cell lung cancer.

Objective To investigate the correlation between the number of resected lymph nodes(LNs) and the prognosis of patients with node-negative esophageal carcinoma.Methods A retrospective review of 429 patients receiving esophagectomy with morden two-field lymphadenectomy for cancer between January 1998 and December 2008 was performed.All patients were proved without lymph node involvement histopathologically.The prognostic impact of the number of negative LNs and the clinicopathologic factors were analyzed.Results The overall median survival time was 63.0 months,and the 1-,3-,and 5-year overall survival rates were 78.5％,64.0％ and 51.2％,respectively.Survival analysis confirmed that the number of negative LNs and the depth of tumor invasion were showed to be independent prognostic factors.Patients with a high number of negative LNs had better overall survival than patients with a low number of negative LNs(P ＜ 0.05).The patients had better long-term survival outcomes with dissected LNs counts of more than 15 for cases with pT1 tumor(P ＜ 0.05),and more than 20 for cases with pT2-3 tumor(P ＜ 0.05).Conclusion The number of negative lymph nodes is an independent prognostic predicting factor for node-negative esophageal carcinoma.Sufficient dissection of LNs is recommended to improve the survival of patients with node-negative esophageal carcinoma.
