Objective To explore the prediction efficiency of multilayer perception (MLP) model in prediction of diabetes mellitus (DM) complicated with coronary heart disease (CHD) by TCM personality and constitutions; To provide a new method for objective prediction. Methods This research utilized single factor logistic regression to filter out variables, which were significant factors of TCM personality and constitutions as analytic variables for MLP and multivariate logistic regression to establish TCM prediction model of personality and constitutions for DM complicated with CHD. The prediction efficiency of the above models were tested by receiver operating characteristic curve (ROC curve). Results The sensitivity, specificity and AUC of MLP were 0.915 (0.862, 0.968), 0.846 (0.793, 0.912) and 0.913 (0.806, 0.987) respectively, which was better than the logistic regression, while these indexes of logistic regression were 0.834 (0.695, 0.953), 0.762 (0.623, 0.901), and 0.869 (0.730, 0.941) respectively. Conclusion The MLP model is better than logistic regression model in prediction of DM complicated with CHD by TCM personality and constitutions.

OBJECTIVE To study the prediction effect of TCM physical personality and constitution on the risks of MD complicated with CHD.METHODS TCM physical personality and constitution of 110 T2MD patients were tested by five pat-tern personality inventor and five-five constitution.CHAID model of decision tree in EXCEL and SPSS was used to establish disease risk model of MD complicated with CHD predicted by TCM personality and constitution types.And the prediction ac-curacy of the model was evaluated.RESULTS Tested by cross validation,the prediction accuracy of MD disease model estab-lished with the Shao-yin personality,Yin-cold constitution and blood-stasis constitution as the predictor variables was relatively higher(93.6%),and three rules for predicting CHD risk were obtained.CONCLUSIONS The prediction rules of the MD complicated with CHD by TCM personality and constitution are consistent with the traditional understanding of Chinese medi-cine,which provides a reference for high-risk population's early screening,CHD prevention and treatment,clinical differentia-tion and treatment.

Objective:To analyze the mortality rate and morbidity rate of lymphoma among residents in Luwan District of Shanghai from 2004 to 2011.Methods:The data of lymphoma in permanent residents of Luwan District were collected from the database of cancer registration and management system in Shanghai.The mortality rate and morbidity rate of lymphoma were calculated.The rates were standardized by the demographic composition developed in the Fifth Nationwide Census in the year 2000.The temporal trend of lymphoma mortality rate and morbidity rate was assessed.Results:A total of 319 cases of lymphoma were diagnosed from 2004 to 2011, accounted for 3.06% of the total patients with malignant diseases.Of those cases, 10 cases were Hodgkin lymphoma (HL), 245 cases were non-Hodgkin lymphoma (NHL), and 64 cases were multiple myeloma (MM).The crude incidence of HL, NHL, and MM among males were 0.19/105, 5.43/105 and 1.28/105 respectively;and 0.34/105, 4.33/105 and 0.89/105 among females respectively.A total of 200 cases died of lymphoma during the 8 year period, including 2 deathed from HL, 148 deathed from NHL, and 50 deathed from MM.The crude mortality rates among males were 0.03/105, 3.50/105 and 0.93/105 respectively;and 0.01/105, 2.22/105 and 0.66/105 respectively among females.Both the mortality rate and morbidity rate of HL were very low.For NHL, both the mortality rate and morbidity rate increased significantly after 50 years of age;while for MM, the majority of cases and deaths occurred after 45 years of age.There were some fluctuations of lymphoma incidence during 2004-2011, but not significant.Standardized mortality showed an increasing trend from 2004 to 2011.Conclusions:Both the incidence and mortality rates of lymphoma in Luwan District of Shanghai from 2004 to 2011 were higher compared to the rates of Chinese urban areas during the same period.It is important to identify risk factors of lymphoma to take effective control measures.

OBJECTIVETo investigate the distribution of the single nucleotide polymorphisms (SNPs) in CAPN10 gene in Chinese population and their relation with type 2 diabetes mellitus in Han people of Northern China.

METHODSCAPN10 gene was sequenced to detect SNPs in 27 samples of different nationalities in China. 5 SNPs were genotyped with single-base extension (SBE) method to perform case-control study in 156 normal Han people of Northern China and 173 type 2 diabetes and the 3 positive loci reported in the article were performed haplotype analysis. One positive locus was also analyzed with transmission-disequilibrium test (TDT) and sib transmission-disequilibrium test (STDT) in 68 type 2 diabetes pedigrees (377 cases).

RESULTSA total of 40 SNPs were identified in length of 8,936 bp, with an average of 1 in every 223 bp; The SNPs in CAPN10 gene did not distribute evenly and the SNPs in Chinese was different from that reported in American Mexicans. There was no significantly statistical difference in the allele frequency of the 5 SNPs between case and control (P > 0.05), and the haplotype frequencies in the two groups were not much different (P > 0.05). There was no positive results in TDT and STDT analysis (P > 0.05).

CONCLUSIONSThe SNP distribution of CAPN10 gene varies with different nationalities. The studied SNPs in CAPN10 gene may not be the major susceptibility ones of type 2 diabetes mellitus in Han people of Northern China.

OBJECTIVETo study the function of 5 single nucleotide polymorphisms (SNPs) of the PRKCZ gene, a susceptibility gene for type 2 diabetes in Han population of North China, in the pathogenesis of the disease.

METHODSBioinformatic methods and reporter gene activity determination were used to analyze the function of the 5 SNPs.

RESULTSThe reporter gene activities of different alleles of 2 SNPs, rs427811 and rs809912, were obviously different, which implies that these 2 SNPs might be susceptibility loci of the disease.

CONCLUSIONThe PRKCZ gene is further confirmed to be a susceptibility gene for type 2 diabetes in Han population of North China. Two SNPs in the gene play a role in the pathogenesis of the disease by affecting the expression level of PRKCZ gene.

OBJECTIVETo improve the prognosis of patients with abdominal trauma.

METHODSBetween January 1993 and December 2005, 415 patients were enrolled in this research. The patients consisted of 347 males and 68 females with mean age of 36 years (ranging from 3-82 years). All abdominal traumas consisted of closed traumas (360 cases, 86.7%) and open traumas (55 cases, 13.3%).

RESULTSA total of 407 cases (98.1%) were fully recovered from trauma and the other 8 cases (1.9%) died of multiple injuries. The mean injury severity score (ISS) of all patients was 22 while the mean ISS of the patients who died in hospital was 42. Postoperative complications were seen in 9 patients such as infection of incisional wounds (6 cases), pancreatic fistula (2 cases) and intestinal fistula (1 case). All these postoperative complications were cured by the conservative treatment.

CONCLUSIONCareful case history inquisition and physical examination are the basic methods to diagnose abdominal trauma. Focused abdominal ultrasonography is always the initial imaging examination because it is non-invasive and can be performed repeatedly with high accuracy. The doctors should consider the severity of local injuries and the general status of patients during the assessment of abdominal trauma. The principle of treatment is to save lives at first, then to cure the injuries. Unnecessary laparotomy should be avoided to reduce additional surgical trauma.

OBJECTIVETo observe the effect of chronic arsenic exposure on cerebral cortex and serum metabolics of mice and explore the mechanism of arsenic neurotoxicity.

METHODSTwelve 3-week-old male C57BL/6J mice were randomly assigned into exposure group and control group and exposed to sodium arsenite (50 mg/L) via drinking water and deionized water for 12 weeks, respectively. After the exposure, arsenic level in the cerebrum was determined by hydride generation-atomic fluorescence spectrometry. The metabolites in the cerebral cortex and serum were determined using gas chromatography-mass spectrometry (GC/MS) analysis. Principal component analysis (PCA) was used to analyze the difference of the metabolites between the exposure and the control groups. Online tools for analyzing metabolic pathways were used to identify the related metabolites pathways.

RESULTSArsenic content in the brain of exposure group was significantly higher than that in the control group (P<0.05). The mice exposed to arsenic had a higher level of citric acid, phenylalanine, tyrosine, histidine and lysine in the cerebral cortex (P<0.05). Serum levels of serine, glycine, proline, aspartate and glutamate were significantly higher while α-ketoglutaric acid level was significantly lower in the exposure group than in the control group (P<0.05). PCA analysis showed a significant difference in cerebral cortex and serum metabolites between the two groups.

CONCLUSIONChronic arsenic exposure may affect the function of the central nervous system by interfering with amino acid metabolism and tricarboxylic acid cycle, which may be one of the mechanisms of arsenic neurotoxicity.

BACKGROUNDAcute kidney injury (AKI) has been recognized as a major healthcare problem affecting millions of patients worldwide. However, epidemiologic data concerning AKI in China are still lacking. The objectives of this study were to characterize AKI defined by RIFLE criteria, assess the association with hospital mortality, and evaluate the impact of AKI in the context of other risk factors.

METHODSThis prospective multicenter observational study enrolled 3,063 consecutive patients from 1 July 2009 to 31 August 2009 in 22 ICUs across mainland China. We excluded patients who were admitted for less than 24 hours (n = 1623), younger than 18 years (n = 127), receiving chronic hemodialysis (n = 29), receiving renal transplantation (n = 1) and unknown reasons (n = 28). There were 1255 patients in the final analysis. AKI was diagnosed and classified according to RIFLE criteria.

RESULTSThere were 396 patients (31.6%) who had AKI, with RIFLE maximum class R, I, and F in 126 (10.0%), 91 (7.3%), and 179 (14.3%) patients, respectively. Renal function deteriorated in 206 patients (16.4%). In comparison with non AKI patients, patients in the risk class on ICU admission were more likely to progress to the injury class (odds ratio (OR) 3.564, 95% confidence interval (CI) 1.706 - 7.443, P = 0.001], while patients in the risk class (OR 5.215, 95% CI 2.798-9.719, P < 0.001) and injury class (OR 13.316, 95% CI 7.507-23.622, P < 0.001) had a significantly higher probability of deteriorating into failure class. The adjusted hazard ratios for 90-day mortality were 1.884 for the risk group, 3.401 for the injury group, and 5.306 for the failure group.

CONCLUSIONSThe prevalence of AKI was high among critically ill patients in Chinese ICUs. In comparison with non-AKI patients, patients with RIFLE class R or class I on ICU admission were more susceptibility to progression to class I or class F. The RIFLE criteria were robust and correlated well with clinical deterioration and mortality.
