Objective To investigate the value of the model for end-stage liver disease (MELD) and Child-Turcotte-Pugh (CTP) score in predicting the prognosis of patients with liver cirrhosis.Methods Seventy patients with liver cirrhosis were selected.The MELD and CTP score before surgery was calculated and was analyzed the correlation between the two models was analyzed.The prognosis ability by the area under the receiver operating characteristic (ROC) curve was evaluated.Results Twenty three cases (32.9％,23/70) appeared post operative serious complication.The scores of MELD and CTP in complication group (23 cases) was (19.58 ±5.90),(8.84 ± 1.87) scores,the scores of MELD and CTP in without complication group (47 cases) was ( 12.27 ± 2.94),(6.10 ± 1.12) scores,there were significant differences between two groups (P ＜ 0.01 ).According to the MELD score,70 patients was divided into ＜ 14 scores group(30 cases),14 - 23 scores group(28 cases),＞ 23 scores group( 12 cases),the rate of complication was 10.0％(3/30),35.7％( 10/28 ) and 83.3％(10/12),there were significant differences among three groups(P＜ 0.05).According to the CTP score,70 patients were divided into A grade(29 cases),B grade (25 cases) and C grade( 16 cases),the rate of complication was 10.3％ ( 3/29 ),36.0％ (9/25) and 68.8％ ( 11/16 ),there were significant differences among three groups (P ＜ 0.05 ).The results of Pearson correlation analysis showed that the MELD score and CTP score had significant correlation (r =0.874,P ＜ 0.01 ).The area under the ROC curve of the MELD score and CTP score in prognosis the perioperative complication was 0.877 (95％ CI:0.84 - 0.95 ) and 0.852 (95％ CI:0.83 - 0.94),there was no significant difference ( U =0.157,P ＞ 0.05 ).Conclusion Both MELD and CTP score can accurately predict the short term prognosis of patients with liver cirrhosis.

Objectives To explore the clinical significance of autoantibodiesin individuals who accept a routine physical examination.Methods From April to June 2012, the serum of 932 individualsincluding 649 males and 283 females, from department of routine physical examination center of Peking Union Medical College Hospitalwerecollected , it uesd IIF for ANA, line immunoassay ( LIA) for specific ANAs antibodies and ELISA for the other antibodies , includinganti-CCP antibodies , AMA-M2, ACL antibodies and anti-anti-β2GPⅠantibodies.Chi-square test was used for data measurement of positive rate of autoantibodies in men and women;Fisher′s exact test was used when the data not meet the conditions of Chi-square test.Individualswith high-risk of autoimmune disease according to the results ofautoantibodies ( Titersof autoantibodies≥2-fold cut-off and accompanied with other autoimmune diseases related laboratory abnormalities) were recalled to visit doctor.Results Of the 932 cases, the overall positive rate of ANA was 11.27%.The positive rate of ANA was19.79%inwomen, which was significantly higher than thatin men (7.09%)(χ2 =32.6, P<0.01); the overall positive rate of ANAswas 8.69%, and the positive rate of ANA was13.43%inwomen, whichwas significantly higher than that in men ( 6.63%) (χ2 =11.49, P <0.01);the overall positive rates of AMA-M2, anti-CCP antibodies , anti ACL antibodies and anti β2GPⅠantibodies were 3.22%, 0.54%, 2.90%and 0.21% respectively , which were 2.83%, 0.71%, 3.18%and 0.71 % in women , and 3.39%, 0.46%, 2.77% and 0.00% in men respectively , there was no statistically significant of positive rate between female and male 58 patients accounting for 6.22% in high-risk of autoimmune disease were recalled , of which 15 cases, accounting for 1.61% were diagnosed or highly suspected of autoimmune diseases (AID) of the 15 patients, 11 patients accounting for 1.18% were diagnosed AID, including 6 CTD, 3 pSS, 1 RA and 1 pSS/PBC;4 patients were highly suspected as AID , including 3 suspected CTD and 1 suspected pSS.The titers concentration of the positive antibodies in patients with confirmed or suspected AID ≥ 3 times cut-off.Conclusions The positive rate of autoantibodies in individuals of physical examination is high , but there is clinical significance when the titers concentration of positive autoantibodies ≥ 3 times of the cut-off.Positive-autoantibodies patients with high-risk of autoimmune disease need professional clinician to provide follow-up, consulting and health education for early discovery, timely diagnosis, and proper treatment of AID.

Objective To analyze the risk factors influencing the occurrence of atherosclerosis in patients with type 2 diabetes, and to construct and evaluate a nomogram prediction model. Methods Multivariate logistic regression was used to analyze the risk factors of atherosclerosis in type 2 diabetes mellitus, and R software was used to build a nomogram prediction model. The accuracy and clinical validity of the model were verified by using H-L fit curve, area under ROC curve and calibration curve. Results The prevalence rate of atherosclerosis was 56.37%. Independent risk factors for atherosclerosis in type 2 diabetes mellitus (P<0.05) were body weight (OR=1.42，P<0.05), glycated serum protein (OR=1.35, P<0.05), lactate dehydrogenase (OR=1.17, P<0.05), alkaline phosphatase (OR=0.79, P<0.05), hyperlipidemia (OR=2.30, P<0.05), stroke (OR=4.20, P<0.05), coronary heart disease (OR=64.54, P<0.05), lower extremity artery disease (OR=24.52, P<0.05), and other endocrine diseases (OR=1.65 , P<0.05). The area under ROC curve was 0.91, the slope of the calibration curve was close to 1, and the H-L fit curve χ²=3.11. The internal verification result of the constructed nomogram prediction model was P=0.93. External verification of patients in the test set showed that the area under ROC curve was 0.91, indicating good differentiation and accuracy of the model. Conclusion The prediction model established by using the risk factors screened in this study has a high accuracy and differentiation, and medical staff can take effective prevention measures according to the individual factors of patients.

ObjectiveTo observe the regulatory effect of Yuyetang on Ghrelin level in rats with type 2 diabetes mellitus （T2DM）-induced cognitive impairment （DCI） and explore the pathway in the prevention and treatment of DCI. MethodThe T2DM model was induced in rats by intraperitoneal injection of streptozotocin （STZ） combined with the high-fat and high-sugar diet （STZ）. The model rats were divided into model group， metformin group （200 mg·kg^-1）， and low-，medium-， and high-dose Yuyetang groups（4.575，9.15， 18.3 g·kg^-1）according to the blood glucose， with 10 rats in each group. A normal group was also set up. The rats were administered with corresponding drugs by gavage for 30 days， and the body weight and blood glucose of the rats in each group were observed and recorded. After drug intervention， the learning and memory abilities of rats were tested by the Morris water maze. After the test， the whole brains of rats were sampled for hematoxylin-eosin （HE） staining to observe the pathological changes in the hippocampal CA1 region， and the expression of Ghrelin in gastric tissues and hippocampal CA1 region was detected by immunohistochemistry. ResultCompared with the normal group ， the model group showed increased blood glucose（P<0.01），reduced body weight（P<0.01），prolonged escape latency（P<0.05，P<0.01）， shortened retention time and movement distance in the target area，decreased number of platform crossings（P<0.01）， abnormal morphology and structure of cells with disordered arrangement and reduced number in the hippocampal CA1 region， and decreased expression of Ghrelin in the serum，hippocampal CA1 region， and gastric tissues（P<0.05， P<0.01）. Compared with the model group， the medium- and high-dose Yuyetang groups showed increased body weight， while all Yuyetang groups showed reduced blood glucose（P<0.01）， shortened escape latency （P<0.05）， prolonged retention time and movement distance in the target area，increased platform crossings （P<0.05， P<0.01）， improved morphology and structure of cells， increased number of normal cell in the hippocampal CA1 region， and elevated Ghrelin levels in the serum， gastric tissues， and hippocampal CA1 region（P<0.05， P<0.01）. ConclusionYuyetang can effectively improve the cognitive ability of DCI rats， and its mechanism may be related to the regulation of Ghrelin levels in the serum， hippocampal CA1 region， and gastric tissues.
