Objective This study aimed to assess the effects of active and passive smoking on chronic kidney disease (CKD) in patients with type 2 diabetes mellitus (T2DM).Methods Seven hundred and five patients with T2DM were recruited in the study and were divided into three groups based on smoking status as active smokers,passive smokers and non-smokers.Twenty-four hour urinary albumin excretion (24hUAE) was measured,and estimate glomerular filtration rate (eGFR) was calculated with age and blood creatinine levels.Results (1) The proportion of CKD in T2DM in the present study was 31.63％ (223/705) with 28.6％ (22/77),30.0％ (15/50) and 29.6％ (73/247) for non-smokers,passive smokers and active smokers in men,and 29.9％ (40/134),35.9％ (66/184) and 7/13 for non-smokers,passive smokers and active smokers in women,respectively.In comparison with non-smokers,a higher risk of CKD was found in both passive and active smokers (OR =1.07 and OR =1.05 in men ; OR =1.31 and OR =2.74 in women,respectively).(2) Compared with non-smokers,passive smokers had a significant higher risk for albuminuria in women (OR =2.02,P =0.016).(3) After adjusting for gender,age,duration of T2DM,BMI,systolic blood pressure,glycosylated hemoglobin A1C and lipids,there was a significant decrease in eGFR between active and never smokers (P =0.018)or passive smokers (P =0.000) in women.No differences could be found in eGFR between each smoking statues in men.Conclusions Smoking exposure alone confers a high risk for CKD in patients with T2DM.Our results highlight an importance in implementation of a smoke-free environment for patients with T2DM.

Acute suppurative thyroiditis (AST) is a rare non-specific infectious disease of thyroid gland.The signs and symptoms of AST may mimic those of a variety of noninfectious inflammatory conditions or other anterior neck infectious diseases.AST is a progressive disease and is also potentially life threatening if devoid of prompt diagnosis and proper treatment.Herein,we report a case in order to call attention to the diagnosis and treatment of AST.

Objective To discuss the relationship between prognosis and different surgical procedures for gallbladder cancer in different stages. Methods The clinical data of 107 patients with gallbladder cancer from January 2001 to May 2007 were retrospectively analyzed. The surgical procedure was chosen according to different stages. Results Eighty-one of the 107 patients (75.6%) were followed up with the median time of 5 years. Of the 10 patients with stage Ⅰ gallbladder cancer who had underwent simple cholecystectomy, 9 survived. Of the 8 patients with stage Ⅱ gallbladder cancer, 3 received palliative cholecystectomy and the median survival time was 12 months, which was significantly shorter than 24 months of the remaining 5 patients who received radical operation (X2= 5.698, P <0.05). Of the 42 patients with stage Ⅲ gallbladder cancer, 18 received radical operation, and the median survival time was 24 months, which was not significantly different from 18 months of the 5 patients who received extended radical operation (X2=0.238, P>0.05). The remaining 19 patients received palliative operation, and the median survival time was 6 months, which was significantly shorter than those of patients received radical operation or extended radical operation (X2=5.772, 6.318, P <0.05). There were 47 patients with stage Ⅳ gallbladder cancer. Seventeen patients received extended radical operation and 30 received palliative operation, and no significant difference upon the median survival time was observed among different surgical procedures (X2=0.001,0.694, P>0.05). The complication recurrence after the extended radical operation was significantly higher than palliative operation (X2=6.039, P<0.05). Conclusions For patients with stage Ⅰ gallbladder cancer, simple cholecystectomy is preferred. Radical operation is good for patients with stage Ⅱ gallbladder cancer. The choose of radical operation or extended radical operation for patients with stage Ⅲ gallbladder cancer should be based on the condition of invasion. Palliative operation could be used to patients with stage Ⅳ gallbladder cancer.

Objective To explore the effects of inducible co-stimulator (ICOS) gene on the cytotoxic activity of cytokine-induced killer (CIK) cells against cholangiocarcinoma cells. Methods CIK-ICOS cells were obtained by stable transfecting ICOS genes into CIK cells through the adenovirus vector whereas untransfected and EGFP-transfected CIK cells were treated as controls. The proliferation and apoptosis of different CIK cells, as well as their cytotoxicity against cholangiocarcinoma cells in the three groups were detected. The expressions of IFN-T, IL-2 and TNF-α in the supernatant of different CIK cells were measured by ELISA. SCID mice with cholangiocarcinoma were randomly divided into CIK group, CIK-EGFP group, CIK-ICOS group and normal saline group. The cytotoxic activity of CIK-ICOS cells against cholangiocarcinoma cells in vivo was observed. Results CIK-ICOS cells displayed better proliferation than CIK cells and CIK-EGFP cells. At day 20 and 23 of culture, the apoptosis rate of CIK-ICOS cells was 0.69% and 0.89%, respectively, while that of the CIK cells was 2.90% and 4.92%. The cytotoxic effect of CIK-ICOS cells at different E: T ratio against cholangiocarcinoma cells was significantly stronger than that of CIK cells and CIK-EGFP cells (F=13.37, 6.46, 25.51, P<0.05). The concentration of IFN-γ in CIK-ICOS cultured supernatant was (49.50±4.73)μg/L, which was significantly higher than that in the cultured supernatant of CIK cells [(30.53±3.73)μg/L] and CIK-EGFP cells [(30.12±2.64)μg/L](F=38.89, P<0.05). The growth of cholangiocarcinoma was significantly slower in CIK-ICOS group than that in CIK group and CIK-EGFP group, whereas the necrosis area of tumor was larger and the CIK cells in CIK-ICOS group was more than those in the other two groups. Conclusions CIK cells had the function of killing cholangiocarcinoma cells in vitro and in vivo. After ICOS genes were transfected into CIK cells, the survival time of CIK cells in vitro was prolonged and the proliferation of CIK cells was enhanced, as well as the secretion of IFN-γ was increased so that the cytotoxicity of CIK cells against cholangiocarcinoma cells in vitro and in vivo was enhanced.

Objective : o evaluate the association between Crohn's disease (CD) and frailty using a Mendelian randomization (MR) approach, so as to provide the evidence for prevention and control strategies. Methods: Genetic association data for CD were collected through the International Inflammatory Bowel Disease Genetics Consortium, with 20 883 samples and 12 276 506 single nucleotide polymorphism (SNP), and genetic association data for frailty were collected through a meta-analysis including 175 226 samples and 7 589 717 SNPs. A forward MR analysis was performed using the inverse-variance weighted (IVW) method with 37 CD-associated SNPs as instrumental variables, and frailty as the study outcome, and a reverse MR analysis was performed with 13 frailty-associated SNPs as instrumental variables and CD as the study outcome. The heterogeneity was assessed using the Cochran's Q test, and the horizontal pleiotropy was assessed using the MR-PRESSO global test and MR-Egger regression. In addition, the robustness of the results was verified with the leave-one-out. Results: Forward MR analysis results showed that patients with genetically predicted CD had an increased risk of frailty index relative to those without CD (β=0.018, 95%CI: 0.011-0.026, P<0.05). Cochran's Q test detected no heterogeneity (P>0.05), and neither the MR-PRESSO test nor the MR-Egger regression revealed horizontal pleiotropy of instrumental variables (both P>0.05). Leave-one-out analysis showed robustness of the MR analysis results. Reverse MR analysis showed no association between frailty index and the risk of CD (OR=0.740, 95%CI: 0.206-2.661, P>0.05). Conclusions Genetically predicted CD is associated with an increased risk of frailty. It is suggested that screening and prevention of frailty should be reinforced among CD patients.

Objective To investigate the association of monocyte chemoattractant protein-1 (MCP-1) promoter -2518A/G gene polymorphism with coronary lesions and in stent restenosis in Tianjin Chinese population. Methods Two hundred and seventy six patients who underwent percutaneous coronary intervention (PCI) and coronary angiography during follow-up were enrolled in the study. The MCP-1 gene promoter polymorphism at position -2518 was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Results The frequencies of three genotypes of MCP-1-2518A/G polymorphism were 21.0% AA, 34. 1% GG,44.9% AG, respectively. There were no statistical differences in the number and the mean degree of stenosis vessels before PCI among 3 genotype groups (all P＞0.05). 113 cases developed in-stent restenosis and 163 cases were free from restenosis. In restenosis group, the AA, AG and GG genotype frequencies were 23.9%, 40.7%, 35.4%, against 19.0%, 47.9% and 33.1% in nonrestenosis group (P = 0. 446) . The frequencies of -2518A and G allele were 44.2%, 55.8% in restenosis group versus 42.9%, 57. 1% in non-restenosis group(P=0. 761). Conclusions The polymorphism of MCP-1-2518 A/G gene may be associated with neither atherosclerosis nor the in-stent restenosis.

Objective To investigate the establishment,operation and performance of external quality assessment(EQA) system for microbial morphology and detection of special drug-resistance in clinical laboratory,and explore the value of the developed system in clinical application.Methods The pictures of known bacteria and fungi colony,gram staining and acid-fast staining from clinical microbiology were distributed to the participating laboratories in Gansu province twice a year at regular intervals.The pictures of standard knowledge points from CLSI,such as special drug resistance were distributed simultaneously.All the participating laboratories were required to complete the interpretation for the pictures and report their resuhs in a scheduled time.Then the resuhs were summarized and analyzed as 3 modes:complete consistency,general consistency and non-consistency.Results During the 2 years when the EQA system for microbial morphology and detection of special drug-resistance were performed for 24 times,the rate of annual complete consistency increased year by year and reached to 91.3％ in 2015.Conclusion The EQA system based on the examinations of microbial morphology and CLSI standard knowledge points for clinical laboratory may supervise the staff of clinical microbiology laboratories in the hospitals at second grade or above to master the skills of morphological identification and learn CLSI knowledge points,so their professional skills of clinical microbiology could be comprehensively improved.
