Objective To determine the relationship between the polymorphism of D2S140 gene and type 2 diabetes mellitus.Methods D2S140 region polymorphism were analyzed with the polymerase chain reaction and short tandem repeat methods in 103 subjects with type 2 diabetes mellitus and 105 nondiabetic subjects.All subjects were biologically unrelated Chinese without a family history of DM.Results There were 7 alleles ranging from 151bp to 163bp in all subjects.The frequencies were 0.01 to 0.37,2 alleles were more common in diabetic patients than in nondiabetic subjects (RR=16.04, P

Objective To investigate the relationship between polymorphisms of candidate genes 〔glucokinase (GCK) gene, NIDDM1(D2S140) gene, fatty acid bindingprotein2(FABP2)gene〕and type 2 diabetes mellitus (DM) in Shandong Chinese Han population. Methods Short tandem repeat (STR) region polymorphisms of GCK gene, NIDDM1 gene and FABP2 gene were analyzed with the polymerase chain reaction and polyacrylamide sequencing gel in 107 patients with type 2 diabetes mellitus and 105 normal subjects. The subjects studied were unrelated and they are Chinese Hans living in Shandong province and no diabetes family history was revealed. Results A5 allele of GCK gene and B2 allele of NIDDM1 gene were positively related with type 2 diabetes (RR=15.70, P0.05). Logistic regression analysis showed that A5 allele and B2 allele were among the risk factors of type 2 diabetes. Conclusion Polymorphic microastellite repeat markers at the glucokinase gene and the NIDDM1 (D2S140) gene locus are associated with type 2 diabetes in Chinese. The polymorphism at the FABP2 locus is not a genetic marker for type 2 DM in Chinese Hans.

Objective To investigate the change of renal tubular function in elderly patients after use of β lactam antibiotic. Methods The elderly patients with pulmonary infection were treated with β lactam antibiotic,the dosage was 50%-70% of normal use. The renal tubular function indicated by urine α1-MG, β2-MG, pro/Cre, NAG/Cre and glomerulus function marked by eGFR, serum creatinine (Cre)), cystatin C were detected during drugs treatment and 7 days after stopping medications. Results The infection was controlled well in 3-7 days after treatment. Urine α1-MG, β2-MG, pro/Cre and NAG/Cre were abnormal before treatment, were elevated in 3, 14 days after using antibiotic, and came down to the level before treatment on 7 days after stopping treatment. The level of Cre and eGFR was (89.0±25.97) μmol/L and (26.39±8.17) ml/min before treatment, then elevated and decreased in 14 days after treatment, respectively, and down to the level before treatment on 7 days after stopping of antibiotic. Cystatin c was abnormal before treatment and did not change significantly after treatment and after stopping antibiotic. Conclusions It is important to protect renal tubular function and to adjust antibiotic dosage according to eGFR during using antibiotic in elderly patients to control infection.

Objective To screen the risk factors of liver metastasis in patients with postoperative colorectal cancer and to set up a mathematic model.Methods One hundred and sixty-eight patients received radical surgery were retrospectively analyzed.Logistics model regression was used to identify the risk factors and ROC test to complete a mathematic model.Results The 3 and 5-year incidence rate of liver metastasis was 25.0％ and 33.3％,respectively.The risk factors of liver metastasis were lymph node metastasis (LNM),tumor invasive depth (TID),histological grading (G) and preoperative serum tumor markers (PSMs).The mathematic model was:logit (P) =-0.931 + 0.973 × LNM + 0.302 x TID + 0.637 x G + 0.042 x PSMs.Conclusion The risk factors of liver metastasis were LNM,TID,G and PSMs,and the mathematic model could be set up.

Objective:To analyze the association of clinical characteristics and laboratory indicators at initial maintenance hemodialysis(MHD)with long-term prognosis in advance-aged patients, and to find influencing factors for the prognosis in advance-aged MHD patients.Methods:This retrospective study was conducted at the Nephrology Department of Beijing Hospital between April 2007 and January 2018.A total of 61 patients receiving first-time hemodialysis at ≥ 80 years of age and undergone regular dialysis for 3 months or longer were enrolled.All patients were followed-up until death or the end of July 1, 2018.Patients were divided into the survivor and non-survivor groups, and differences in clinical characteristics and laboratory indicator values were compared between the two groups.Influencing factors for prognosis in advance-aged MHD patients were analyzed by using multivariate Cox regression.Results:For the 61 subjects, the median follow-up time was 25.8 months.During the follow-up, 32 patients died(52.5%). The main death causes were infectious diseases(40.6%, n=13)and cardiovascular and cerebrovascular diseases(37.5%, n=12). The 1-, 2-, 3-, 4-, and 5-year cumulative survival rates were 75.4%(46/61), 54.1%(33/61), 37.7%(23/61), 22.9%(14/61)and 16.4%(10/61), respectively.The median survival time was 25.8 months for all patients, 27.5 months for patients aged 80-84 years, and 14.9 months for patients aged 85 years and over.The non-survivor group had a higher male ratio(65.6% or 21/32 vs.37.9% or 11/29, χ2=4.678, P=0.031)and lower levels of hemoglobin(85.4±13.0 vs.95.0±17.6 g/L, t=2.867, P=0.019)and albumin(30.3±5.0 vs.34.6±4.8 g/L, t=3.039, P=0.001)than the survivor group.Kaplan-Meier curves indicated that the survival rate decreased with age, and subjects aged less than 85 years had a higher survival rate than subjects aged 85 years and older(the median survival time: 14.9 months vs.27.5 months, Log Rank P=0.006); patients who received continuous renal replacement therapy(CRRT)before dialysis had lower survival rates than patients who did not receive CRRT(the median survival time: 7.8 months vs.29.2 months, Log Rank P=0.002); patients with high serum levels of albumin(≥33 g/L)had higher survival rates than patients with low serum levels of albumin(<33 g/L)(the median survival time: 29.2 months vs.18.9 months, Log Rank P=0.003). Multivariate Cox regression analysis showed that age at initial dialysis( HR=1.136, 95% CI: 1.005-1.285, P=0.041), female( HR=0.409; 95% CI: 0.169-0.994, P=0.048), serum albumin level( HR=0.836, 95% CI: 0.772-0.906, P<0.001)and CRRT before dialysis( HR=6.161, 95% CI: 1.848-20.538, P=0.003)were independent predictors of all-cause mortality in advance-aged patients. Conclusions:Advance-aged patients undergoing hemodialysis have complicated clinical conditions and poor prognosis.Age, gender and serum albumin level at initial dialysis and CRRT before dialysis are independent predictors of prognosis in these patients.

Objective To investigate the clinical characteristics and laboratory examinations in incident dialysis effect on the prognosis of elderly patients undergoing hemodialysis.Methods Ninety-three patients aged 65 years or older initiating hemodialysis were enrolled from Hemadialysis Center of Beijing Hospital from January lst,2007 to June 30th,2016.The duration time of HD of all patients was more than three months.Patients were divided into death group and non-death group.The clinical characteristics and laboratory examinations were compared between the two groups.Cox proportional hazards regression was used for the multivariate analysis to determine independent prognosis factors.Results The average year of patients was 74.2±6.5 years old with 43 months of median time of follow-up.The first two causes of death were infection (n =25,49.0％) and cardiovascular and cerebrovascular diseases (n =16,31.4％).Cox single factor regression analysis showed that the older ages,diabetic nephropathy being the cause of end-stage renal disease (ESRD),complicating with diabetes mellitus or congestive heart failure,the higher Charlson cardiovascular diseases score,ALB being under 35 g/L were correlated with poor outcome respectively(P＜0.05).Cox multivariate regression analysis indicated that older ages (HR =1.056,P =0.021),diabetic nephropathy being the cause of ESRD (HR =2.661,P =0.001),the higher Charlson cardiovascular diseases score (HR =1.675,P =0.010),central venous catheters being vascular access(HR=1.167,P=0.048) on incident dialysis were the main risk factors for mortality in elderly patients.Conclusion The older ages,diabetic nephropathy being the cause of ESRD,the higher Charlson cardiovascular diseases score,central venous catheters being vascular access on incident dialysis are independent risk factors influencing survival of elderly patients.

Objective To explore the clinical pathological characteristics and prognostic factors of patients with neuroendocrine tumor of the appendix.Methods Data of 42 cases of the appendiceal neuroendocrine tumor from June 2006 to June 2016 at Tianjin Police Hospital were analyzed.Tumors were classified according to 2010 WHO classification.The survival curves were drawn using Kaplan-Meier method.Univariate analysis was performed by the Log-rank test.Results There were 27 males and 15 females,with median age of 60 years.Tumors located in the head of the appendix in 37 cases,in the body in 2 cases and at the base in 3 cases.The median of tumor sizes were 1.2 cm.G1 in 17 cases,G2 in 21 cases,G3 in 4 cases.The follow-up rate was 100％.The overall 1-year survival rate was 92％.Conclusions The clinical symptoms of appendiceal neuroendocrine tumors are most often nonspecific.The diagnosis depends on pathological examination and immunohistochemistry,and prognosis varies with pathological grades.
