Covered in the paper is the development of the hospital's surgical information acquisition system during the healthcare reform and upgrading of its performance assessment scheme.Such a system is designed to precisely collect surgery scheduling, daytime surgery, and outpatient surgery workload, conducive to developing a performance assessment scheme based on surgery workload, motivating medical workers, and improving quality of care.

Objective To investigate the presence of radial displacement of the meniscus in knee joint, and discuses its clinical significance. Methods From January 2000 to February, 398 cases underwent MRI because of different symptoms, and were analyzed retrospectively. Of them, 312 were recruited to the study, whose age was more than 18 years without knee operation, serious deformity, bone destruction, fracture, dislocation and tumor. Non-weight-bearing magnetic resonance images (MRI) of 312 patients with symptoms, including 125 males and 187 females aging from 19 to 85 years, were used to evaluate retrospectively for the radial displacement of the meniscus in knees by Kenny's method. The macroscopic observation for menisci were noted separately during total knee replacement(TKR) and knee arthroscopy in 21 and 35 patients respectively. Results In the 312 cases, MRI examinations demonstrated that 52 patients were found with the radial displacement of the meniscus(16.7%),including 47 medial menisci and 6 lateral menisci. There was a statistically difference among each age group (?2=10.18,P

Objective To observe the effect of ultrafiltrated components of three kinds of serum containing phlegm-resolving prescriptions (Huanglian Wendan Decoction, Gualou Xiebai Banxia Decoction, and Erchen Decoction, respectively) on viability of human leukemic monocytic cell line THP-1 derived macrophages and macrophage differentiation to foam cells. Methods THP-1 cells were induced to differentiate into macrophages with phorbol-12-myristate-13-acetate ( PMA) . And then the achieved macrophages were used for the establishment of the atherosclerotic foam cell model after co-incubation with oxidized low density lipoprotein ( ox-LDL ) . Three kinds of serum containing phlegm-resolving prescriptions and blank serum were prepared and ultrafiltered by 10 KD ultrafiltrator, and then were co-cultured with the foam cell model, respectively. The viability of macrophages and the macrophage differentiation to foam cells were tested by methyl thiazolyl tetrazolium ( MTT) assay and oil red staining. Apoptotic rate of macrophages was determined by flow cytometry. Results After THP-1 cells were induced by PMA (100 nmol/L) for 20 hours and then were co-incubated with ox-LDL (50 μg/mL) for 24 hours, a typical atherosclerotic foam cell model was established successfully. The ultrafiltrated components of serum containing Huanglian Wendan Decoction had obvious effects on increasing the macrophage survival rate, decreasing macrophage apoptotic rate, and inhibiting macrophage differentiation to foam cells. The ultrafiltrated components of serum containing Gualou Xiebai Banxia Decoction or Erchen Decoction had an effect on enhancing the macrophage differentiation to foam cells but had no anti-apoptosis action. Conclusion Huanglian Wendan Decoction has anti-atherosclerosis action, which may be related to resisting macrophage apoptosis and decreasing macrophagic lipid-endocytosing function. Erchen Decoction and Gualou Xiebai Banxia Decoction are effective on increasing macrophagic lipid-endocytosing function.

Objective To analyze the spatial distribution characteristics of non-iodized salt at household level based on geographic information system (GIS) in Chongqing.Methods The database of non-iodized salt at county level from 2001 to 2010 was established in Chongqing.By using GIS technology,the spatial distribution and spatial autocorrelation were analyzed by ArcGIS 9.3 software.Results The rate of non-iodized salt was fluctuated between 2.35％-5.78％ during 2001-2006 and the rate was reduced to less than 2.00％ after 2007.The result of spatial autocorrelation analysis on non-iodized salt from 2001 to 2006 indicated that Moran's Ⅰindex was 0.145578,0.078801,0.108033,0.091957,0.127749,0.214302,respectively(Z value was 3.066275,1.977321,2.541619,2.309972,2.900446,3.874203,respectively,all P ＜ 0.05).The spatial distribution of non-iodized salt had marked spatial cluster through Chongqing region from 2001 to 2006.The result of local spatial autocorrelation analysis from 2001 to 2006 indicated that Fengdu and Fuling were two high-risk areas(all P ＜ 0.05).Dianjiang,Yubei,Jiangbei,Wulong and Banan were also confirmed as high-risk areas in 2001,2005 and 2006(all P ＜ 0.05).The results also indicated that the distribution of non-iodized salt in the seven high-risk areas was positively correlated.The result of spatial autocorrelation analysis on non-iodized salt from 2007 to 2010 indicated that Moran's Ⅰ index was 0.018361,0.016186,0.040769,-0.059691,respectively (Z value was 1.093310,0.787361,1.071811,-0.583820,respectively,all P ＞ 0.05).The spatial distribution of non-iodized salt was at random on the whole from 2007 to 2010.However,there were four local high-risk areas.The distribution in Fengdu and Dianjiang was positively correlated,while that in Jiangjin and Shizhu was negatively correlated.Conclusions The distribution of non-iodized salt at households level in Chongqing is changed from spatial distribution before 2006 to random distribution after 2007,but there are high value areas,which should be taken as the focus of monitoring.

Background The multipotent differentiation features of induced pluripotent stem cells (iPSCs) offer a new option for cell replacement therapy of many clinical diseases.In ophthalmology,iPSCs are a good model in studying the pathogenic mechanism of degenerative ocular diseases.A better identification method for iPSCs is critical for analyzing the in vivo biological characteristics of iPSCs.Objective This study was to investigate the feasibility and stability of labeling iPSCs with quantum dots.Methods Human umbilical mesenchymal stromal cells-iPSC lines were cultured and amplified on matrigel,and the characteristics of iPSCs were evaluated by immunofluorescence.Different concentrations (5.0,7.5 and 10.0 nmol/L) of quantum dots with a CdSe/ZnS nuclear shell structure were used to label iPSCs after passaging and proliferation.The labeling outcome was observed with a three-dimensional deconvolution real-time live cells imaging system.The labeled iPSCs were subsequently cultivated,and then changes in fluorescence intensity were examined 7 days after the first and the second passaging of iPSCs.Results iPSCs were observed to grow in a clonal manner under the inverted microscope.The iPSC markers,OCT4 and Nanog,were detected by immunofluorescence.With increasing concentrations of quantum dots,the fluorescence intensities representing the levels of OCT4 and Nanog in iPSCs were gradually elevated,with optimal levels of fluorescence observed at a concentration of 10 nmol/L of quantum dots.The fluorescent labeling of OCT4 and Nanog in iPSCs remained and weakened gradually till day 7 even after the second passage.Conclusions Quantum dots labeling could be used to track iPSCs in a dose-independent manner.The fluorescent signal from the quantum dots labeling the iPSCs lasts 2 weeks at least.

OBJECTIVETo observe the synergic or antagonistic effect of needling acupoints Fengchi (GB 20) and Tianzhu (BL 10), and Jiaji C4-C6 (EX-B2) on vertebro-basilar insufficiency (VBI).

METHODSSelf-control method was used and 20 cases of VBI were respectively treated with acupuncture at Fengchi (GB 20) and Tianzhu (BL 10), Jiaji (EX-B2). Their combination and the changes of vertebro-basilar artery's (VBA) systolic velocity of blood flow was detected.

RESULTSThe VBA's systolic velocity of blood flow after acupuncture were increased in all the 3 groups (P < 0.05 or P < 0.01), with no significant difference among the 3 groups (P > 0.05).

CONCLUSIONAcupuncture at Fengchi (GB 20) and Tianzhu (BL 10) or Jiaji (C4-C6 ) or their combination can increase VBA's systolic velocity of blood flow, improving blood supply of vertebro-basilar artery, but they have no synergic or antagonistic effects.
