Objective: Based on nationwide cardiovascular surgery registry database, to analyze the current status and future development of minimally invasive cardiovascular surgery (MICS) in China.
Methods: There were 45 institutions from 19 provinces nationwide involved in Chinese cardiovascular surgery technique registry study. A total of 16480 adult patients with cardiovascular surgery from 2010-09 to 2012-03 were divided into 2 groups, Conventional surgery group, n=14503 and MICS group, n=1977. The basic clinical conditions were analyzed and compared between 2 groups in order to explore the current status and future development of MICS in China.
Results: Compared with Conventional surgery group, the patients in MICS group had the younger age, better and stable pre-operative condition. In MICS group, compared with 4 other common procedures, the patients who received hybrid procedure had obviously shorter cardiopulmonary bypass (CPB) time, aortic occlusion time, ventilator using time, ICU and in-hospital stay time, meanwhile decreased post-operative drainage volume;except for Robotic surgery, it required less red blood cells and plasma at during and post-operative time, all P<0.01. There were 12 (0.6%) in-hospital death in MICS group, the total complication rate was at 4%.
Conclusion: MICS are widely used in China, its short-term safety and efifcacy are conifrmed. Upon cardiovascular disease spectrum changing, the MICS procedures will be adjusted accordingly.

[Summary] The aim of this study was to examine the association between obstructive sleep apnea-hypopnea syndrome ( OSAHS ) and microalbuminuria in type 2 diabetes mellitus patients. We found that severe OSAHS significantly increases the risk of early renal damage in type 2 diabetes mellitus patients with HbA1C<7% ( lowest oxygen saturation:OR=2. 41, 95% CI 1. 19-8. 08; apnea hyponea index: OR=2. 91, 95% CI 1. 50-9. 11), suggesting that OSAHS may increase the risk for early renal damage in type 2 diabetes mellitus, especially in those with successful control of glucose.

OBJECTIVETo investigate the value of computer-assisted slide-screening system (ThinPrep imaging system, TIS) in the diagnosis of cervical Thinprep smears.
METHODSA total of 19 600 ThinPrep smears were collected, including 9800 slides by TIS-assisted screening from September 2011 to March 2012 and 9800 slides by manual screening from September 2010 to April 2011 as control. The detection rates of abnormal cells and common microbial infection by the different screening methods were compared. With histopathological diagnosis of colposcopic biopsy as the gold standard, the screening efficiency and correlation of cytologic diagnosis among different screening methods were analyzed.
RESULTSCompared with manual screening, the detection rate of abnormal cells in 9800 cases by TIS-assisted screen was increased from 5.4% (525/9800) to 6.8% (665/9800), mainly in the categories of ASCUS and LSIL (P < 0.05). TIS had a higher accordance rate between cytologic diagnosis and histopathological diagnosis in the NILM and ASCUS than that by manual screening. False-negative rate of finding abnormal cells by TIS decreased from 8.5% (17/200) to 0.7% (2/289, P < 0.01) with an increased sensitivity compared to manual screening, although the specificity was similar. Both TIS and manual screening had advantages and disadvantages respectively in the detection of microbial organisms. TIS improved screening efficiency by 50%.
CONCLUSIONTIS improves not only the screening efficiency but also the detection of abnormal cells with a reduced false negativity, and it therefore has a broad application prospect.

OBJECTIVETo observe the effect of Kanglaite injection(KLT) on the proliferation and telomerase activity of mesangial cells in rats.
METHODMTT, telomere repeat amplification protocal (TRAP), ELISA, PAGE and silver-stain were applied to detect the growth rate and telomerase activity of MC after stimulation of KLT and IL-1.
RESULTThe growth rate of MC was enhanced by IL-1 stimulation, which was accompanied with a redection of the activity of telomerase. Adversely, the growth rate of MC was reduced by KLT, which was accompanied with an enhancement of activity of telomerase. Moreover, the growth rate of MC and the activity of telomerase were both inhibited by the combinative use of IL-1 and KLT without any influence from the sequence of their administration.
CONCLUSIONKLT could inhibit proliferation and telomerase activity of MC with or without pre-stimulation with IL-1. KLT might be useful to prevent and treat glomerular nephritis related to MC proliferation.

OBJECTIVETo investigate the relationship between respiratory diseases onset and the meteorological factors in the same period and in a specific environment. METHODS METHODS: By using the data of daily incidence of respiratory diseases obtained from Dongzhimen Hospital Affiliated to Beijing University of Chinese Medicine from January 1, 1998 to December 31, 2007, and the data of 16 items of meteorological factors (such as the average, maximum, and minimum temperatures, etc., including meteorological factors derived) obtained from the Beijing Municipal Meteorological Observatory, mathematical statistical methods were applied to achieve the non-linear correlation analysis, or the correlation test, between the incidence of respiratory diseases and the time-related meteorological factors.
RESULTSThe simple correlation coefficients of the relationship between the incidence of respiratory diseases and 9 meteorological elements, including the average values of temperature, maximum temperature, minimum temperature, degree of comfort, precipitation, vapor pressure, low cloud cover, change of vapor pressure, and change of wind speed, were all greater than 0.8286, in which one of the relationship between the incidence of respiratory diseases and the maximum temperature is as high as 0.9670. Statistical tests showed R>Rα=0.05 and F>Fα=0.05.
CONCLUSIONSThe incidence of respiratory diseases was closely correlated to meteorological factors, such as air temperature, vapor pressure, precipitation, wind speed, etc. To a certain extent, this conclusion confirmed the scientificity and objectivity of the theory of five evolutive phases and six climatic factors (Wu Yun Liu Qi ) in Huang Di Nei Jing (The Yellow Emperor's Canon of Internal Medicine).

OBJECTIVETo study the effect of bitter-cold herbs easing dampness method (BCHEDM) plus Sanhuang Yilong Decoction (SYD) combined with methotrexate (MTX) on expression levels of interleukin-1 (IL-1), IL-6, and IL-17 in rheumatoid arthritis (RA) patients of accumulated dampness-heat syndrome (ADHS).
METHODSFrom January 2011 to January 2013 recruited were 90 RA inpatients of ADHS at Department of Integrative Medicine on Rheumatoid Disease, General Hospital of Chengdu Military Region. They were assigned to the treatment group (45 cases) and the control group (45 cases) according to the random digit table produced by SPSS 11.5 Software. Patients in the treatment group were treated by heavy bitter-cold herbs plus SYD combined with MTX, while those in the control group were treated by MTX alone. Expressional levels of IL-1, IL-6, and IL-17 in serum were detected by enzyme linked immunosorbent assay (ELISA) before treatment, at week 2 and 4 after treatment. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and disease activity score in 28 joints (DAS28) were detected as well.
RESULTSAfter two or four weeks of treatment, ESR, CRP, and DAS28 decreased more in the treatment group than in the control group with statistical difference (P < 0.05, P < 0.01). After four weeks of treatment, IL-1, IL-6, IL-17, ESR, CRP, and DAS28 in the treatment group were all lower than before treatment and those of the control group at corresponding time points with statistical difference (P < 0.01).
CONCLUSIONSYD combined MTX could play roles of improving inflammatory indices within 2 weeks, and inhibiting the expression of IL-1, IL-6, and IL-17 within 4 weeks.
