ABSTRACT

Objective To understand the periodicity of the incidence of hand, foot and mouth disease (HFMD) in representative provinces from different climatic zones in China, and to analyze the seasonality and the factors influencing the HFMD transmission rate, to provide a scientific reference for the prevention and treatment of HFMD. Methods Five climate-representative provinces including Hainan, Hunan, Shandong, Qinghai and Inner Mongolia were selected as research objects. Wavelet analysis was used to analyze the cyclic pattern of HFMD incidence. Time series susceptible infected recovered (TSIR) model was established to examine the HFMD transmission rate of the five provinces and of the entire country. The parameters in the TSIR model were estimated by markov chain monte carlo (MCMC). Linear regression model was used to analyze the effects of climate factors, school terms and the Spring Festival travel rush on the transmission rate of HFMD. Results (1) HFMD incidence in the provinces and the entire country exhibited annual or semi-annual cycles and the transmission rates in all provinces showed obvious seasonality with similar patterns. February to May was the peak period of HFMD transmission rate. (2) The transmission rate of HFMD was affected by the climate or the contact rate, depending on which factor was dominant. Conclusions The transmission rate of HFMD had obvious seasonality, which had increased significantly in February, and it was necessary to strengthen its prevention and control during the Spring Festival.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the analgesic and sedative effects of inhaling a mixture of nitrous oxide and oxygen on burn patient during and after dressing change.</p><p><b>METHODS</b>A total of 240 burn patients hospitalized in the Institute of Burn Research of Changhai Hospital Affiliated to the Second Military Medical University, Department of Burns of the First People's Hospital in Zhengzhou, and Department of Burns and Plastic Surgery of General Hospital of Ningxia Medical University from October 2011 to September 2012 were enrolled in our study, and they were all in accordance with the inclusion criteria. The 240 patients were divided into control group (n = 60, treated with inhalation of oxygen during dressing change) and treatment group (n = 180, treated with inhalation of a mixture of 65% nitrous oxide and oxygen during dressing change) according to the computer-generated list of random number. The other treatments in control group and treatment group were the same. Before, during, and after dressing change, heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), oxygen saturation (SO2), and adverse effects were observed. The degree of pain and anxiety felt by the patients were respectively evaluated with the visual analogue scale (VAS) and Chinese version of the burn specific pain anxiety scale (C-BSPAS) at the same time points as above. Data were processed with analysis of covariance, chi-square test, analysis of variance, and rank sum test.</p><p><b>RESULTS</b>There were no significant differences between control group and treatment group in the levels of HR, SBP, DBP, and SO2 before dressing change (with F values respectively 0.76, 0.06, 1.11, 0.70, P values all above 0.05). Compared with those of control group, the levels of HR, SBP, DBP, and SO2 in treatment group were significantly ameliorated during dressing change (with F values respectively 81.78, 146.36, 226.44, 205.62, P values all below 0.01). After dressing change, the levels of DBP in the two groups were close (F = 0.31, P > 0.05), but the levels of HR, SBP, and SO2 showed statistical differences (with F values respectively 7.02, 8.69, 12.23, P < 0.05 or P < 0.01). Before dressing change, the VAS scores were approximate between control group and treatment group (Z = 0.21, P > 0.05). Compared with those in control group (9.4 ± 0.7, 1.7 ± 2.5), the VAS scores were significantly lowered in treatment group during and after dressing change (1.6 ± 1.3, 0.7 ± 1.1, with Z values respectively 11.84, 3.35, P values all below 0.01). There was no significant difference in C-BSPAS score between control group and treatment group before dressing change (Z = 0.62, P > 0.05). Compared with those in control group (75 ± 13, 73 ± 12), the C-BSPAS scores in treatment group were decreased during and after dressing change (9 ± 15, 9 ± 14, with Z values respectively 11.91, 12.28, P values all below 0.01). There were no obvious adverse effects in two groups before, during, and after dressing change.</p><p><b>CONCLUSIONS</b>A mixture of nitrous oxide and oxygen seems to have obvious analgesic and sedative effects on burn patients during dressing change, and it can be widely used.</p>

ABSTRACT

<p><b>BACKGROUND</b>Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation at the synovial membrane. Although great progress has been made recently in exploring the etiology and pathogenesis of RA, its molecular pathological mechanism remains to be further defined and it is still a great challenge in determining the diagnosis and in choosing the appropriate therapy in early patients. This study was performed to screen candidate RA-associated serum proteins by comparative proteomics to provide research clues to early diagnosis and treatment of RA.</p><p><b>METHODS</b>Sera isolated from 6 RA patients and 6 healthy volunteers were pooled respectively and high-abundance proteins were depleted by Plasma 7 Multiple Affinity Removal System. The protein expression profiles between the two groups were then compared by two-dimensional gel electrophoresis (2-DE) and the proteins over/under-expressed by more than 3-fold were identified by mass spectrometry analysis. To validate the differential expression levels of the identified proteins between the two groups, ELISA was performed in two of the identified proteins in individual sera from 32 RA patients and 32 volunteers.</p><p><b>RESULTS</b>Eight proteins which over/under-expressed in sera of RA patients were identified. Among them, chain A of transthyretin (TTR) was under-expressed, while serum amyloid A protein, apolipoprotein A (ApoA)-IV, ApoA-IV precursor, haptoglobin 2, ceruloplasmin (Cp), immunoglobulin superfamily 22 and HT016 were over-expressed. ELISA test confirmed that Cp expressed remarkably higher while TTR obviously lower in RA group compared with volunteer group.</p><p><b>CONCLUSION</b>There were 8 identified proteins differentially expressed between RA group and volunteer group, which might be candidate RA-associated proteins and might be promising diagnostic indicators or therapeutic targets for RA.</p>

ABSTRACT

Group A,the differences among the three groups were statistically significant(P0.05). TCR,CCR,DAP,OD,BRC in Groups B and C showed trends of increasing,the differences in terms of the contents of BMP-RⅠamong the 3 phases were statistically significant(P0.05);the ER in Group B and C showed a trend of decreasing,thee difference between 4- and 8-week and 4- and 12-week were signifieantly dif- ferent(P0.05).Conclusion After application of glucocorticoid for a short term,pathological changes maintained and showed trends of inereasing in early stage.HBO can reverse these changes.The outcome of 3-course HBO therapy is better than that of 1-course therapy.
