Objective To explore the association of single nucleotide polymorphism-SNP44 of Calpain 10 gene with genetic susceptibility to type 2 diabetes in Kunming.Methods The polymorphism of site UCSNP44(T/C) in Calpain 10 gene was detected by Polymerase chain reaction and Allele specific amplification(PCR-ASA)in 131 type 2 diabetic patients and 131 non-diabetic controls who were selected using case-control study in the Kunming urban communities.Results The frequency of"C"allele and"TC"gene of SNP44 in type 2 diabetic patients was significantly higher than that in the controls.Conclusion The study suggested that the polymorphism-SNP44 of Calpain10 gene may be associated with genetic susceptibility to type 2 diabetes in Kunming population.

To study the antiarrhythmic effect of the newly developed alpha/beta-blocker TJ0711, a variety of animal models of arrhythmia were induced by CaCl2, ouabain and ischemia/reperfusion. Glass microelectrode technique was used to observe action potentials of right ventricular papillary muscle of guinea pig. The onset time of arrhythmia induced by CaCl2 was significantly prolonged by TJ0711 at 0.75, 1.5 and 3 mg x kg(-1) doses. TJ0711 (1.5 and 3 mg x kg(-1)) can significantly shorten the ventricular tachycardia (VT) and ventricular fibrillation (VF) duration, the incidence of VF and mortality were significantly reduced. On ischemia-reperfusion-induced arrhythmic model, TJ0711 (0.25, 0.5, 1 and 2 mg x kg(-1)) can significantly reduce the ventricular premature contraction (PVC), VT, VF incidence, mortality, arrhythmia score with a dose-dependent manner. At the same time, rats serum lactate dehydrogenase (LDH) and creatine kinase (CK) activities decreased significantly by TJ0711 (1 and 2 mg x kg(-1)). Ouabain could cause arrhythmia in guinea pigs, when TJ0711 (0.375, 0.75, 1.5 and 3 mg x kg(-1)) was given, the doses of ouabain inducing a variety of arrhythmia PVC, VT, VF, cardiac arrest (CA) were significantly increased with a dose-dependent manner. In the TJ0711 0.1-30 micromol x L(-1) concentration range, guinea pig right ventricular papillary muscle action potential RP (rest potential), APA (action potential amplitude) and V(max) (maximum velocity of depolarization) were not significantly affected. APD20, APD50 and APD90 had a shortening trend but no statistical difference with the increase of TJ0711 concentration. TJ0711 has antiarrhythmic effect on the sympathetic nerve excitement and myocardial cell high calcium animal arrhythmia model. Myocardial action potential zero phase conduction velocity and resting membrane potential were not inhibited by TJ0711. APD20, APD50 and APD90 were shortened by TJ0711 at high concentration. Its antiarrhythmic action mechanism may be besides the action of blocking beta1 receptor, may also have a strong selective blocking action on alpha1 receptor and reducing intracellular calcium concentration.

Nimesulide is a new non-steroidal anti-inflammatory drug (NSAID). In this paper, its antiinflammatory, analgesic and antipyretic effects in mice rat or rabbit were evaluated. Nimesulide inhibited the ear oedema induced by croton oil in mice (ED50=49. 2 mg ? kg-1). It inhibitated rat hind paw oedema induced by carragreenin (ED50= 2.75 mg ? kg-1). Oral dose (0. 6 mg ? kg-1) showed sup-pressive effect on adjuvant arthritis in rat. Oraldose (100 mg ? kg-1) decreased writhing induced by acetic acid. Similar effect was observed in hot plate test on mice. Nimesulide (2 mg ? kg-1) decreased body tempreture elevated by injecting peptone in rabbit (P

Objective:To examinethe absolute numbers of cluster of differentiation (CD4) + T cell subsets in peripheral blood of patients with rheumatism and further to develop a new immunomodulatory therapies which aimed to restore their imbalanced CD4 + T lymphocyte subpopulation. Methods:A total of 6 395 rheumatic patients [4 430 females, 1 965 males, mean age (49±15) years] and 206 healthy controls (HCs) were enrolled in this retrospective cross-sectional study, which included rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), ankylosing spondylitis (AS), Psoriatic arthritis (PsA), systemic sclerosis (SSc), primary Sj?gren′s syndrome (pSS), Be?het's disease (BD), dermatomyositis/polymyositis (DM/PM), gout and vasculitis. Some patients received treatment combined with immunoregulatory drugs (IMiDs) such as low-dose interleukin (IL)-2, rapamycin, metformin, retinoic acid and coenzyme Q10. The absolute numbers of T helper cell (Th)1, Th2, Th17 and regulatory T cell (Treg) in peripheral blood (PB) of these individuals were measured by Flow Cytometery (FCM). Independent sample t test and paired sample t test were used to compare the levels of CD4 + T cell subsets in PB of patients and HCs, before and after treatment respectively, and P<0.05 was considered statistically significant. Results:Compared with HCs, the mean absolute number of Treg was significantly decreased [(31±15) cell/μl vs (27±17) cell/μl, t=3.407, P<0.01] and the ratio of Th17/Treg was increased in all patients [(0.3±0.2) vs ( 0.4±0.7), t=-9.508, P<0.01]. There was a significant increase in the number of Th17 in patients with AS [(10±8) cell/μl, t=-5.403, P<0.01], PsA[ (11±11) cell/μl, t=-3.829, P<0.01], SSc [(7±6) cell/μl, t=3.114, P<0.01], BD [(11±9) cell/μl), t=-4.774, P<0.01] and gout [(11±9) cell/μl, t= -4.604, P<0.01) , and we observed lower level of Treg in patients with RA[(28±15) cell/μl, t=3.032, P<0.01], SLE [(21±21) cell/μl, t=6.836, P<0.01], AS [(28±15) cell/μl, t=2.216, P<0.05], SSc [(27±16) cell/μl, t=3.698, P<0.05], BD [(27±17) cell/μl, t=2.502, P<0.05], DM/PM [(27±22) cell/μl, t=2.974, P<0.01) and gout [(28±15) cell/μl, t=2.079, P<0.05). After IMiDs combination treatment, the levels of CD4 + T subsets were increased. Interestingly, the expansion of Treg was much more dramatical than those of other effector T cells, resulting in a decrease in ratios of Th17/Treg, especially in SLE [(0.6±1.0) vs (0.5±0.4), t=3.157 , P<0.01]. Conclusion:Impaired balance of pro- and anti-inflammatory immune cells, especially insufficiency of Treg, might be a cornerstone of the pathogenesis of rheumatism. The new immunomodulatory therapies could relatively specifically promote Treg proliferation and restored patients' autoimmune tolerance, which isexpected to provide a new strategy for the treatment of rheumatism.

Objective To evaluate the efficacy and safety of the bundles of treatment protocol for patients with acute brain injury (ABI) complicated by acute lung injury (ALl)/acute respiratory distress syndrome (ARDS).Methods A total of 83 patients with acute brain injury complicated by ALI/ARDS were randomly divided into experimental group (n =41) and control group (n =42).The control group was treated with the routine bundle protocol while the experimental group was treated with an intensive bundle protocolin addition to the routine bundle protocol.The data was collected,and the effectiveness and safety of the two bundles of treatment protocol were evaluated.Results The results of heart rate (HR),SpO2,and PO2/FiO2 in the two groups showed significant differences before and after treatment.The improvement of PO2/FiO2 in the experimental group occurred earlier and was more significant compared tothe control group,24 hours after treatment.The mechanical ventilation time,ICU stay time,and total hospitalization time for the experimental group were significantly different (P ＜ 0.05) from the control group.The 28-day mortality and morbidity of ventilator-associated pneumonia showed no significant difference (P ＞ 0.05) between the two groups.Conclusion The treatment of acute brain injury complicated by ALI/ARDS by the two bundles of treatment protocol is effective.Compared to the conventional treatment bundles,the intensive treatment bundles can significantly improve oxygenation,and shorten the mechanical ventilation time required,as well as ICU and total hospital stay.

Objective To investigate the clinical significance of homocysteine(Hcy) and glycated hemoglobin (HbA1c) in patients with diabetic retinopathy.Methods From March 2013 to February 2015,a total of 168 patients with diabetes from Beijing Jishuitern Hospital were divided into diabetic retinopathy group (76 cases,32 male,44 female,average age 62.97 ± 12.46) and non-diabetic retinopathy group (92 cases,46male,46 female,average age 58.14 ± 13.71),and 65 cases of healthy subjects (46male,46 female,average age 60.24 ± 10.85) were enrolled as normal control group as well.Hcy and HbA1c were detected in all groups.Multiple independent samples nonparametric tests were used to compare the difference between groups.The concentrations of Hcy and HbA1c between DR group and NDR group were analysised by ROC curve analysis.Result The Hcy levels in normal control group,NDR group and DR group were 7.00 (4.55-10.50) μmol/L,12.45 (10.30-15.10) μmol/L,20.10 (16.63-25.68) μmol/L respectively.The HbA1c levels in normal control group,NDR group and DR group were 5.30 (5.00-5.70) ％,6.80 (5.83-8.03) ％,7.25 (6.50-8.60) ％ respectively.There was no significant difference in Hay and HbA1c levels between groups (P ＜ 0.01);Compared with non-diabetic retinopathy group,levels of Hcy,HbA1c in diabetic retinopathy group were obviously higher;The optimal diagnostic cut-off values of Hcy was 14.35 μmol/L,at this cut-off value,the sensitivity was 96.05％,specificity was 68.48％;The optimal diagnostic cut-off values of HbA1c was 6.05％,at this cut-off value,the sensitivity was 98.68％,specificity was31.25％.Conclusion Patients with Diabetic retinopathy might have hyperhomocystinemia,and detection of Hcy may contribute to the early diagnosis of diabetic retinopathy.

Objective To retrospectively review the epidemiological data from 159,242 patients hospitalized after traumatic brain injury in traffic accidents and provide epidemiological evidences for the prevention and treatmentmeasures.Methods Patient data were collected using the Chinese Trauma Database for the years 2001-2007.Epidemiological features of age,gender,time distribution,length of hospital stay,state of injury,and treatment outcome were recorded.Results Age of the patients was (33.01 ± 15.20) years and ratio of male to female patients was 2.39∶ 1.The majority were aged 21-50 years with the 31-40 age group were more vulnerable.Annual average growth of age was 3.92％.Within a year,number of the patients accounted for 54.10％ from July to December with it reached the peak in October.Mean length of stay was 20.20 days with the longest stay in the ≥90 age group and shortest stay in the ≤10 age group.Mean hospital charges was 13 689.8 yuan with the ≤10 age group occupying the least and 51-60 age group occupying the most.Overall cure rate was 66.92％ and mortality was 4.22％.Proportion of severe traumatic brain injury in traffic accidents increased and related cure rate decreased with increased age.Male patients showed higher death rate and lower cure rate compared with female patients.Conclusions Incidence of traffic accidents-related traumatic brain injury is the most in the young and middle-aged population and is prevalent in the second half year.There should be emphasis on the aged or male patients.Measures to prevent and treat the injury may produce better results when defined based upon these epidemiologic features.
