Objective To investigate clinical characteristics and outcome of patients with liver cirrhosis complicated with diabetes,and to explore the differences of clinical characteristics and prognosis between hepatogenous diabetes (HD) and type 2 diabetes mellitus (T2DM).Methods From November 2010 to April 2012,246 patients with liver cirrhosis were collected and divided into liver cirrhosis complicated with diabetes (LC-DM) group (n=72) and liver cirrhosis without diabetes (LC) group (n=174).LC-DM group was then sub-divided into HD group (n=33) and T2DM group (n =39).All the patients were followed up until death or the study endpoint.The clinical characteristics,prognosis and indicators of glucose metabolism were compared and analyzed.Oral glucose tolerance test and insulin C-peptide release test were conducted in part of patients in LC-DM group.Student t test was performed for mean comparison between two groups.Chi-square test was used for count data and rate comparison between two groups.The death related factors of liver cirrhosis were analyzed by Logistic regression analysis.Results The percentage of alcoholic liver cirrhosis of LC-DM group was 18.1 ％ (13/72),which was higher than that of LC group (6.9％,12/ 174) and the difference was statistically significant (x2=6.946,P=0.008).In HD group,the percentage of patients with diabetes family history was 9.1％ (3/33),which was lower than that of T2DM group (30.8％,12/39),the percentage of alcoholic liver cirrhosis was 30.3％ (10/33),which was higher than that of T2DM group (7.7％,3/39),the total bilirubin level ((43.4±57.7) μmol/L) was higher than that of T2DM group ((22.6 ± 13.3) μmol/L),the total cholesterol level ((3.3 ±1.2) mmol/L) was lower than that of T2DM group ((4.0±1.6) mmol/L),and the differences were statistically significant (x2=5.093 and 6.177,t=2.178 and 2.014,P=0.024,0.013,0.033 and 0.048).The duration of hospitalization,Chiid-Pugh score,the incidence of upper gastrointestinal bleeding,the incidence of hepatic encephalopathy,electrolyte disturbances and mortality of LC-DM group were all higher than those of LC group and the differences were statistically significant(t=2.389 and 2.270,x2 =6.496,5.572,5.194,19.646,all P＜0.05),and there was no significant difference between HD group and T2DM group(all P＞0.05).The blood glucose levels of HD group at different time point (0,30,60,120,180 min) were all lower than those of T2DM group and the differences were statistically significant (t=3.175,2.345,3.444,3.090,3.542,all P＜0.05).The fasting insulin level of HD group was close to that of T2DM group,the insulin levels of HD group at other time point (30,60,120,180 min) were all higher than those of T2DM group and the differences were statistically significant (t =3.084,2.881,3.648,2.840,all P＜ 0.05).There was obvious hyperinsulinemia in HD group.At 0,30,60,120,180 min,C-peptide level of HD group was at normal levels,and which of T2DM group was lower than normal.Child-Pugh grade C was an independent predictor factor of death in patients with liver cirrhosis (OR =3.056,95 ％ CI:1.268 ～ 7.346,P=0.013).Conclusions Compared with liver cirrhosis patients without diabetes,the liver function of patients complicated with diabetes was worse,and the incidence of complication and mortality was higher.However there was no significant difference between HD group and T2DM group.

Objective To investigate recurrence of colorectal adenoma (CRA)after polypectomies and colonoscopic surveillance,and to explore risk factors related to CRA recurrence.MethodsFrom June 2005 to December 2009,in the Fist Affiliated Hospital of Anhui Medical University,the clinical data of 283 hospitalized patients who underwent CRA polypectomy and met the study criteria were collected and followed up.The recurrence rate of CRA after polypectomies,the relationship between colonoscopic surveillance interval and CRA recurrence and risk factors related to recurrence were analyzed.The colonoscopic surveillance interval,frequency and the reason for no colonoscopic surveillance were also analyzed.ResultsA total of 235 post-polypectomies CRA patients were successfully followed up,the follow-up rate was 83.0％ (235/283).The shortest follow-up period was 12 months and the longest was 66 months,the median follow-up time was (35.1 ± 14.2)months.A total of 115 patients were underwent colonoscopic surveillances,the surveillance rate was 49.4％ (115/233).The recurrence rate was 45.0％ (50/111) in colonoscopic surveillance group.A total of 118 patients were without colonoscopic surveillances.Age over 60 years,body mass index over 25 kg/m2 and multiple adenomas (≥ 2) were significantly related with CRA recurrence,and the difference was statistical significant (P＜ 0.05).The rate of awareness that CRA needed regular surveillance group without surveillonce was significantly lower than that of group with surveillance.(P＜0.01).ConclusionThe recurrence rate of CRA after polypectomies is high.Age,high body mass index and multiple adenomas are predicted independent risk factors for CRA recurrence.Lacking awareness of the importance of regular surveillances after polypectomies is the main reason for low colonoscopic surveillance rate after polypectomies in our hospital.

Objective To screen the prevalence of nutritional risk in cirrhotic inpatients by Nutritional Risk Screening 2002 (NRS 2002) and explore the relationship between nutritional risks and outcomes.Methods NRS 2002 was used to identify the nutritional risk of 200 cirrhotic inpatients between May 2010 and May 2011.The Child-Turcotte-Pugh (CTP) grade,fatality,complications,and length of stay within 6 months were followed up to explore the relationship between nutritional risks and outcomes.Results The prevalence of nutritional risk screened by NRS 2002 was 53.5％ in cirrhotic patients.The prevalence of nutritional risk was 39.0％,59.4％,and 60.0％ respectively in patients with CTP grade A,B,and C (P =0.029).Compared with those without nutritional risks,patients with nutritional risks had significantly higher incidences of complications and fatality (P =0.000 and 0.013) and longer hospital stay (P =0.001).Conclusion The nutritional risk increases along with the CTP grade.Patients with nutritional risks tend to have poorer outcomes.The influence of nutrition support on the outcome of patients with liver diseases needs further research.

Objective To explore the risk factors associated with surgery and postoperative recurrence in patients with Crohn's disease (CD).Methods A total of 183 patients diagnosed as CD from January 2008 to December 2013 were enrolled.Forty-six patients after surgery were assigned to surgery group,and 137 non-surgical CD patients were assigned to control group.All the patients were followed up until the endpoint of the study or death,and the follow-up period was at least 12 months.Typing was according to the Montreal classification.The risk factors associated with surgery and postoperative recurrence were analyzed by Logistic regression.Results The surgery rate of CD patients was 25.1 ％ (46/183),the postoperative clinical recurrence rate of surgery group was 39.1％ (18/46),and the recurrence time was 20 months (7～42 months).Before surgery,the rate of definite diagnosis of CD was only 13.0％ (6/46).Stricture (odd ratio (OR)=5.836,95％ confidence interval (CI) 2.199 to 15.487,P＜0.01) and penetration (OR=25.706,95％oo CI 7.091 to 93.190,P＜0.01) were independent risk factors for the surgery.Furthermore,perianal disease(OR=23.550,95％CI 1.311 to 422.912,P=0.032) and lack of prophylaxes treatment after surgery (OR=58.701,95％CI 1.803 to 1 991.000,P=0.022) were independent risk factors for postoperative clinical recurrence.Conclusions Stricture and penetration are risk factors for surgery.Perianal disease and lack of prophylaxes treatment after surgery are risk factors for postoperative clinical recurrence.

Objective To evaluate the role of serum immunoglobulin G4 (IgG4) in differentiating autoimmune pancreatitis (AIP) from pancreatic cancer(PC).Methods The database,including Medline,EMBASE,Science Direct,Springer link,CBM,Wanfang,VIP and Cnki were searched by computer and the publication date was before April 1,2015.The studies on evaluating the accuracy of IgG4 in differentiating AIP from PC were screened and selected according to strict determined inclusion and exclusion criteria.Quality assessment was made by QUADAS scale.The publication bias were assessed by Stata12.0 software.The heterogeneity of included articles,calculate the pooled sensitivity,specificity,positive likelihood,negative likelihood were anylyzed by Meta-Disc1.4 software,respectively,and draw the summary ROC (SROC) curve.Results A total of 13 English articles were included and 1403 patients were involved.The pooled sensitivity was 74％ (95％ CI 70％ ～ 78％),the pooled specificity was 93％ (95％ CI 91％ ～ 95％),the positive likelihood ratio was 10.74 (95％ CI 7.16 ～ 16.11),the negative likelihood ratio was 0.25 (95％ CI 0.17 ～0.35) and the area under SROC curve was 0.9340.Conclusions IgG4 has high diagnostic efficacy but low misdiagnosis rate in differentiating AIP from PC,which can be used as one of early diagnostic markers for AIP.

Objective To evaluate the value of fecal calprotectin (FC) and stool lactoferrin (SL) for detecting endoscopic activity and monitoring postoperative recurrence of Crohn disease.Methods Publications in Pubmed,Embase,Science Direct,Springer Link,CBM,Cnki,Wan fang and VIP database before January 1 st 2016 were searched manually.Papers were screened according to inclusion and exclusion criteria.Quality assessment was conducted by QUADAS-2 scale.Meta-Disc 1.4 was used to analyze the heterogeneity of included articles.The pooled sensitivity,specificity,positive likelihood,negative likelihood were calculated respectively and the SROC curve was drawn.Stata 12.0 was used to assess the publication bias.Results A total of 19 papers in English language were included.The pooled sensitivities of FC,SL in detecting endoscopic activity and FC in monitoring postoperative recurrence of Crohn disease were 86％ (95％ CI:84％-88％),72％ (95 ％ CI:66％-79％),80％ (95％ CI:75％-84％),respectively.The specificities were 71％ (95％CI:67％-75％),84％ (95％ CI:74％-91％),65％ (95％ CI:59％-70％),respectively.The areas under the SROC curve were 0.865 6,0.834 6,0.811 0 respectively.The cut-off values of FC in detecting endoscopic activity of Crohn disease were set to ＜ 100 μg/g,100-＜200 μg/g or ≥ 200 μg/g with the area under the SROC curve being 0.898 7,0.788 8,0.888 8,respectively.The cut-off values of FC in monitoring postoperative recurrence of Crohn disease were set to 100-＜ 150 μg/g,150-＜200 μg/g or ≥ 200 μg/g with the areas under the SROC curve being 0.677 4,0.859 4 and 0.759 5,respectively.Conclusion FC and SL have higher diagnostic efficiency than C-reaction protein and are worthy of clinical promotion in detecting endoscopic activity and monitoring postoperative recurrence of Crohn disease.However,endoscopy cannot be replaced.

Objective To investigate the accuracy of prognosis risk assessment and clinical applicability of Rockall (RS) and Blatchford scoring system (BRS) for acute nonvariceal upper gastrointestinal bleeding (ANVUGIB). Methods From January 2009 to December 2009, the clinical date 195 ANVUGIB patients who met the standards with complete information and treated in The First Affiliated Hospital of Anhui Medical University were recorded. Each patient's scores of RS and BRS were calculated for risk stratification. Patients were followed up for 30 days after discharged.Death or the prognosis of disease in 30 days after discharged was considered as clinical study endpoints.Checked prognostic capacity of these two scoring system. Results In the 195 patients, there were 150 years, mean age was 53.97±18.34 years. 90 patients' age was over sixty (elderly group), 105 less than sixty (non-elderly group). 182 patients survived (93.3%), while 13 dead (6.7%). In survival patients, 11were re-bleeding (5.6 %). Mortality ( 12.2 %, 11/90), the percentage of patients with comorbidities (43.3%, 39/90) and taking aspirin (24. 4%, 22/90) were higher in elderly patients than non-elderly patients (1.9%, 2/105; 16.2%, 17/105; 11.4%, 12/105 respectively)(P＜0.05).The AUC of RS in predicting risk of death was 0.742 (P=0.004) and re-bleeding was 0.469 (P=0.101). For BRS score system, the AUC of predicting risk of death was 0. 493 (P= 0. 067)and rebleeding was 0.341(P=0.092). The RS score was positively correlated with length of hospital stay,however there was no statistically significant between BRS score and length of hospital stay.Conclusion RS score system was good at predicting the risk of death, and the score was positively correlated with length of hospital stay. While it was poor in predicting the risk of re-bleeding. BRS performed poorly in predicting the risk of both death and re-bleeding, so it was not suitable for predicting the risk of hospitalized patients.

Objective To explore the clinical characteristics and medicine treatment of patients with severe ulcerative colitis (UC),the efficacy of rescue treatment in patients with glucocorticoid (GCS) resistant severe UC,and the clinical risk factors in patients with GCS-refractory severe UC.Methods From January 2001 to December 2012,clinical,laboratory,endoscopy,imaging data and medication of treatment of 106 patients with severe UC were retrospectively analyzed.Then the patients were followed up,and the clinical efficacy and under endoscopic presentation of Mayo score were evaluated.Logistic regression analysis was performed to analyze the high risk factor of GCS-refractory severe UC.Results Among 106 patients with severe UC,95 were chronic relapse type accounting for 89.6 ％.The percentage of patients with defecation times over six was 73.6％ (78/106),with severe purulent bloody stool was 51.0％ (54/106),and with moderately or severe abdominal pain was 83.0％ (88/106).The percentage of diffuse colon type was 83.0％ (88/106),endoscopic presentation of Mayo score over two was 87.7％ (93/106).Hemoglobin decreased in 65.1％ (69/106) patients,blood platelet increased in 48.1％ (51/106) patients,C-reaction protein elevated in 88.7％ (94/106) patients,and hypoalbuminemia decreased in 42.5％ (45/106) patients.Account to 89.6％ (95/106) of patients with severe UC received GCS treatment,and the percentage of induced remission was 64.2％ (61/95),effective rate was 16.8％ (16/95),and ineffective rate was 18.9％ (18/95).The percentage of GCS refractory was 35.8％(34/95).There were 23 patients with GCS resistance and 11 patients with GCS dependence.Ten patients with GCS resistant severe UC accepted medicine rescue therapy.Five cases were treated with cyclosporin A,of which two cases induced remission,one case was effective,and two cases were ineffective.Another five cases were treated with infliximab,of which three cases induced remission,and two cases were ineffective.The results of Logistic regression analysis showed that severe anemia (OR=6.750,95％CI:2.656 to 17.152,P＜0.01),elevated blood platelets (OR=4.032,95％CI:1.226 to 13.261,P=0.015) and albumin level less than 25 g/L (OR =3.022,95 ％ CI:1.236 to 7.390,P =0.022) were risk factors of GCS-refractory severe UC.Conclusions GCS resistant or dependent occurred in part of patients with severe UC.Patients with G-CS resistant severe UC receive rescue treatment of cyclosporin A or infliximab.Severe anemia,elevated blood platelets,albumin less than 25 g/L may be clinical predicting factors in patients with GCS-refractory severe UC.

Objective To explore the clinical correlation of the variation of plasma homocysteine (HCY), melatonin (MLT) and ulceative colitis (UC). Methods The clinical data of 112 UC patients was collected, and 110 normal healthy persons as control. The level of plasma HCY and MLT was detected by high pressure liquid chromatography-fluorescence detection (HPLC-FD) method. The level of plasma folate ( FA) and vitamin B12 was detected by enzyme-linked immunosorbent assay (ELISA) method. The correlation of these four indexes and UC was analyzed. Results The serum level of HCY in UC patients was significantly higher than that in normal healthy persons [(11. 27± 7.26) μmol/L vs (8. 19±4. 81) μmol/L, P = 0. 000]. The serum level of MLT in UC patients was significantly lower than that in normal healthy persons [(49. 06 + 31. 40) pg/ml vs (64. 28±41. 16) pg/ml,P=0. 008]. The serum level of FA in UC patients was significantly lower than that in normal healthy persons [(7. 64 + 1.95) nmol/L vs (9. 14 + 1.23) nmol/L, P = 0. 005]. The serum level of vitamin B12 in UC patients was significantly lower than that in normal healthy persons [(108. 64 ±32. 22) pmol/L vs (112. 64±33. 33) pmol/L, P = 0. 004]. There was no correlation between plasma HCY, MLT and UC disease activity degree, range, disease duration, erythrocyte sedimentation rate (ESR), or C reactive protein (CRP) in UC patients. There was no significant correlation between MLT and HCY in UC patients. Conclusions The serum level of HCY is higher in UC patients than that in normal control, and MLT is lower than that in normal control. However there is no significant correlation between them.
