Objective To study the clinic characters of patients with latent autoimmune diabetes in adults (LADA). Methods We evaluated the prevalence of acute and chronic complications in the LADA patients with serum antibodies to glutamic acid decarboxylase (GADA) or to islet cell cytoplasmic antigens (ICA). The prevalence of acute and chronic complications were further compared with that in patients with acute onset type 1 or type 2 diabetes. Results The mean age, BMI, fasting and postprandial C peptide levels of the LADA patients were higher than those of type 1 diabetes and lower than those of type 2 diabetes. Of the LADA patients, 29.3% had ketosis. Although the frequency of repeated attack of ketosis in the LADA patients was similar to that in type 1 diabetes, the duration from diabetic onset to first ketosis in the LADA patients was much longer. The prevalence of retinopathy in the LADA patients was 19.5%, which was similar to that in type 1 diabetes. The prevalence of cataract in the LADA patients was 48.8%, which was similar to that in type 2 diabetes. Less LADA patients had microalbuminuria, compared with the other groups. There was no difference in the prevalence of overt nephropathy, neuropathy and hyperlipidemia among the three groups. The prevalence of coronary heart disease in the LADA patients was similar to that in type 2 diabetes. The prevalence of hypertension in the LADA patients was higher than that in type 1 but lower than that in type 2 diabetes. Conclusion The clinic characters as well as acute and chronic complications in LADA patients are different from those in type 1 and type 2 diabetes.

Objective To evaluate the efficacy of puerarin for prevention of brain injury in the patients undergoing open heart surgery under cardiopulmonary bypass (CPB).Methods Thirty ASA physical status Ⅲ patients of both sexes,aged 50-64 yr,weighing 50-75 kg,scheduled for elective cardiac valve replacement under general anesthesia,were randomly divided into 2 groups (n =15 each) using a random number table:control group(group C) and puerarin group (group P).Puerarin 400 mg was infused intravenously over 30 min immediately at skin incision in group P and the equal volume of 5％ glucose-sodium chloride injection was given in group C.Before induction of anesthesia (T0),at 30 min of CPB (T1),immediately after aortic unclamping (T2),and at 6,12 and 24 h after termination of CPB (T3.5),blood samples were collected from the jugular venous bulb for determination of the plasma concentration of neuron-specific enolase (NSE) and S-100 β protein.P300 eventrelated potential latency and amplitude were determined and cognitive function was assessed by Mini-Mental State Examination (MMSE) score at 1 day before surgery and 7 days after surgery.The patients were diagnosed as having post-operative cognitive dysfunction when MMSE score before surgery-MMSE score after surgery ≥ 2,or when M MSE score≤ 24.Results Compared with group C,the concentrations of plasma NSE and S-100 β protein were significantly decreased at T15,and P300 event-related potential latency was shortened,P300 event-related potential amplitude was increased,and the incidence of postoperative cognitive dysfunction was decreased at 7 days after operation in group P.Conclusion Puerarin can prevent the brain injury in the patients undergoing open heart surgery under CPB.

Objective To observe the curative effect of abdominal acupuncture on postoperative pain of patients with mixed hemorrhoid after Milligan-Morgan hemorrhoidectomy.Methods A total of 100 mixed hemorrhoid patients with postoperative pain after Milligan-Morgan hemorrhoidectomy under spinal anaesthesia from September of 2014 to December of 2015 were included into the study.The patients were evenly randomized into trial group and control group.The trial group was treated with abdominal acupuncture at acupoints of Shuifen,Guanyuan,Qihai,Sanxing needles under Qihai,lower Fengshi,Tianshu for 15-30 min.The control group was treated with intramuscular injection of Tramadol Injection 0.1 g.Before treatment and 0.5,1,2,3 hours after treatment,the pain visual analogue scale (VAS) scores and body activity scores were recorded.Results (1) After treatment,pain VAS scores of the two groups at different time points were obviously decreased(P ＜ 0.05 compared with those before treatment),and the decrease of pain VAS scores of the treatment group 0.5 hours after treatment was superior to that of the control group (P ＜ 0.05),but there was no significant difference between the two groups at other time points (P ＞ 0.05).(2) After treatment,body activity scores of the two groups at different time points were obviously decreased(P ＜ 0.05 compared with those before treatment),but the difference was insignificant between the two groups(P＞ 0.05).(3) The average dose of Tramadol Injection used in the trial group was 0.013 ± 0.034 1 g,while was 0.103 ± 0.017 7 g in the control group,the difference being significant (P ＜ 0.05).Conclusion The analgesic effect of abdominal acupuncture is similar to that of Tramadol Injection.For its safety,and being cheap,practical and painless,abdominal acupuncture can be expected to be another option of effective analgesic method for the postoperative pain of patients with mixed hemorrhoid after Milligan-Morgan hemorrhoidectomy.

Objective To investigate the application of secondary prevention medication for patients with high risk of recurrent ischemic stroke in Changzhou city,analyze the reasons for decreased medication compliance,and evaluate the current secondary prevention medication.Methods We investigated 300 consecutive hospitalized patients with acute non-cardiogenic and ischemic stroke high risk.High risk of recurrent stroke was defined as ESSEN Stroke Risk Score (ESRS) ≥3.Different ESRS scales consisting of different parameters were analyzed.All of the patients received standard secondary prevention of ischemic stroke at discharge.After three months and a year follow up,antiplatelet therapy,therapy of risk factors (hypertension and diabetes mellitus),lipid lowering therapy,and medication compliance were investigated.Results Except for age (x2 =126.54,P =0.000) and previous cerebral ischemic stroke or transient ischemic attack (TIA) (x2 =21.27,P =0.000),there were no significant differences in other risk factors (hypertension,diabetes,previous myocardial infarction,heart diseases,smoke) in patients with different ESRS scale scores (all P＞ 0.05).Antiplatelet therapy utilization was 98.3％ (295/300),antihypertensive and antidiabetic drug use rates were 95.0％(255/268) and 100％(72/72),statin use rate reached to 99％ (297/300) at discharge.After three months follow up,medication compliance in hypertension and diabetes mellitus therapy was the best [88.1％(222/252)and 86.2％ (56/65)],followed by aspirin [82.0％ (228/278)],and clopidogrel [6.1％ (17/278)].The medication compliance in lipid lowering therapy was the worst [60.1％ (167/278)].After a year follow-up versus the previous three-month follow-up,the medication compliance in hypertension and diabetes mellitus therapy was increased,but had no significant difference [89.9 ％ (220/245) vs.88.1％ (222/252),93.4％(57/61)vs.86.2％(56/65),P＞0.05],and the medication compliances inantiplatelet therapy with aspirin and clopidogrel,and lipid lowering therapy were increased significantly [93.2％ (245/263)vs.82.0％ (228/278),30.8(81/263) vs.6.1％ (17/278),88.9％ (234/263) vs.60.1％ (167/278),all P＜0.01].The increment of use rate was higher in clopidogrel therapy than in aspirin therapy.Conclusions The secondary prevention medication achieves certain efficacies in patients with high risk of recurrent ischemic stroke in changzhou city.Long term follow-up and good communication between doctor and patient can effectively improve the medication compliance in secondary prevention,and can increase the use rate of antiplatelet therapy in patients with high risk of recurrent ischemic stroke.

Objective To investigate the association of the rs 2118181 polymorphism of FBN-1 gene ( encoding Fibrillin-1 ) and the risk of acute aortic syndrome ( AAS ) in Chinese Han population. Methods Genomic DNA was extracted from the blood of 206 patients suffering AAS and 209 individual-matched controls.The dideoxy chain termination method was used to determine the genotypes of rs 2118181 single nucleotide polymorphisms .Results The TT frequency of rs 2118181 genotype was significantly higher in the patients with AAS , especially with Intramural Haematoma ( IMH ) than in the controls ( 62.1%, 70.4% vs.52.5%, P<0.05).Carriers of CT or CC genotype had a less risk for AAS , especially for IMH, compared with carriers of TT genotype.The odds ratio were 0.66 (95%CI:0.45-0.98, P=0.040) and 0.46 (95%CI:0.24-0.87, P=0.016) respectively.After adjusting for age, sex, body mass index, hypertension , body mass index , smoking , diabetes mellitus , the odds ratio for AAS was 0.66 ( 95% CI:0.44-0.99 , P=0.048 ) .However , there was no significant difference on the frequencies of rs 2118181 genotype between the two subgroups of classical aortic dissection and intramural haematoma . Conclusions The rs2118181 polymorphism of FBN-1 gene is correlated to the sporadic AAS , especially to IMH, in Chinese Han population .The carriers of TT genotype are vulnerable to AAS , especially to IMH , compared with the non-carriers.

Objective: To access the risk for smoking on morbidity of acute ST-segment elevation myocardial infarction (STEMI) at different gender and age population. Methods: A case-control study was conducted in 2026 STEMI patients and 2026 control subjects with matched gender and age (±2 years) in our hospital from 2010-01-14 to 2016-02-27. The relationship between smoking and STEMI morbidity was analyzed. Results: Smoking was an important risk factor for STEMI morbidity in male gender and it was negatively related to age, as STEMI in young male smokers (≤45 years): adjusted OR=7.000, 95% CI 4.235-11.570; in middle age male smokers (46-59 years):adjusted OR=5.296, 95% CI 3.904-7.185 and in elder male smokers (≥60 years): adjusted OR=4.686, 95% CI 2.860-4.751. Conclusion: Smoking is a major risk factor for STEMI morbidity, while it is different from age and gender; the young male smokers have the highest risk to suffer from STEMI.

【Objective】 To investigate the effectiveness of current indicators in initial screening and retest before donation and access the optimal testing strategies. 【Methods】 Data of initial screening (rate method for ALT, colloidal gold method for HBsAg) and retest (rate method for ALT, ELISA for HBsAg) of 18 510 platelet donors in our center from January 2019 to December 2021 were collected, and the results were retrospectively analyzed and compared in terms of different years and number of donations. 【Results】 From 2019 to 2021, data of initial screening and retest of platelet donors were as follows: 1) the deferral rate of ALT and HBsAg was 12.98% (2 403/18 510) vs 0.26%(40/15 412); 2) the deferral rate of ALT was 13.19% (712/5 398) vs 0.20%(9/4 410)in 2019, 13.33% (873/6 549) vs 0.06%(3/5 387)in 2020 and 11.05% (725/6 563) vs 0.07%(4/5 615)in 2021; for initial screening, significant difference was noticed in ALT reactivity in 2021 as in comparison to other two years(P<0.05); 3) the reactive rate of HBsAg was 0.43% (23/5 398) vs 0.18%(8/4 410)in 2019, 0.66% (43/6 549) vs 0.20%(11/5 387)in 2020 and 0.41% (27/6 563) vs 0.09%(5/5, 615) in 2021. For initial screening, HBsAg deferral in 2021 was significantly different from 2019, while similar with 2020. 4) Among ALT deferral samples in the retest, 68.75% (11/16) were ALT≥45 U/L. Among HBsAg reactive samples, 91.67% (22/24) were reactive by single reagent. 【Conclusion】 Setting the threshold value of ALT for platelet donors in initial screening as less than 45 U/L can effectively reduce the reactive rate in the retest. HBsAg screening only for first-time platelet donors can reduce the detection cost. Adding pre-donation detection indicators according to local prevalence of transfusion transmitted diseases is conductive to reduce the discarding rate of platelets.

In order to investigate the effects of porin genes ompW,ompS and ompD on the biological properties and virulence of Salmonella typhimurium,the corresponding mutant strains were con-structed using the λ Red homologous recombination system,and the growth curves,motility,bio-chemical properties,in vitro genetic stability,biofilm-forming ability,drug resistance,and lethal dose at half capacity(LD50)between the standard strain and each mutant strain were detected by comparative assays for Salmonella typhimurium.The results showed that,compared with the standard strain,the ompD and ompW mutation had less effect on the growth rate and motility of the bacteria,while the ompS mutation significantly reduced the growth rate and motility;none of the three genetic mutation affected the biochemical characteristics of Salmonella typhimurium,nor the genetic stability,but affected its susceptibility to a variety of commonly used antibiotics to varying degrees and caused a highly significant decrease(P＜0.01)in the ability to form a biofilm,and the results showed that the three mutant strains had a significant reduction in the ability to form a biofilm.The result of LD50 virulence assay showed that all three genetic mutation led to a decrease in the virulence of Salmonella typhimurium,among which the ompS mutant strain showed the most obvious decrease in virulence,LD50 was 25 times that of the standard strain.In conclusion,mutations of the pore protein ompW,ompS,and ompD genes can affect some biological properties of Salmonella typhimurium.The results of this study laid an experimental foundation for further research on the biological functions of the pore protein ompW,ompS and ompD genes and Salmonella pathogenicity.
