Objective To make a status survey on type2 diabetic patients with metabolic Syndrome in middle-aged inhabitants.Methods 338 inpatients with type 2 DM including 179 male and 159 female,aged 46?5 years,with complete records in the computer database.Results The prevalent rates of the complications in group of 40～yrs type2 diabetic patients were 17.8% combined with coronary atherosclerotic heart disease,50.9% with hypertension,18.1% with left ventricular dilatation,53.6% with hypertriglyceridemia,46.2% with lower HDL,54.7% with obesity and 38.8% with metabolic Syndrome,respectively.These prevalent rates in the 40-year-old group were all lower than those in groups above 60 years,and the rates was higher in patients whose BMI was above 25(kg/m2).Conclusion There was high prevalence in type 2 diabetic patients with metabolic Syndrome,and was related with the age and obesity.Obesity was an independent risk factor for MS.

AIM:To study the clinical effect of silica gel drainage tube combined with lomefloxacin hydrochloride eye ophthalmic gel in the treatment of lacrimal duct obstruction.METHODS:Totally 86 cases (138 eyes) of lacrimal duct embolism treated in our hospital from February to December 2015 were divided into 43 cases (68 eyes) as control group and 43 cases (70 eyes) of the observation group according to whether they were treated with lomefloxacin hydrochloride eye ophthalmic gel.Patients in the control group were treated with silica gel drainage, while the observation group was treated with lomefloxacin hydrochloride eye ophthalmic gel on the basis of the control group.The total effective rate, serum hypersensitivity C-reactive protein (h-CRP) level, complications and recurrence rate were observed and compared between the two groups.RESULTS:The total effective rate in the patients with obstructive nasolacrimal duct, common lacrimal duct obstruction, and lacrimal duct obstruction in observation group were 95.2%, 100.0%, 96.7%, higher than those in control group (P<0.05).There was no significant difference between the two groups in preoperative serum h-CRP levels (P>0.05).The serum levels of h-CRP in patients in the observation group at 3d and 7d after operation respectively were 2.40±0.84g/mL, 1.94±0.84g/mL, lower than those of control group at the same time (P<0.05).The complication rate of the observation group was 1.4%, which was lower than that of the control group (P<0.05).Follow up for 6-18mo, the recurrence rate was 11.4% in the observation group, which was significantly lower than the control group (P<0.05).CONCLUSION:The combination of silica gel drainage tube and lomefloxacin hydrochloride eye ophthalmic gel in the treatment of obstruction of lacrimal duct has good clinical efficacy, low inflammatory reaction, low complication rate and low recurrence rate.

Objective To explore different socio-demographic and clinical characteristics for early onset patients (EOP) with psoriasis and late onset patients (LOP) with psoriasis in Chinese population and to provide scientific evidences for establishing comprehensive prevention and treatment strategy for psoriasis.Methods Cross-sectional study was performed.A total of 942 diagnosed psoriasis patients who paid a visit to outpatient clinic in a tertiary hospital in China from 12th September 2013 to 19th May 2015 was consecutively enrolled and investigated.Exploratory analysis was conducted to detect the association between disease onset age and patients features.Results Among 942 enrolled psoriasis outpatients,the average age was (40.6 ± 13.6) years with a range from 5 to 80 years.The sex ratio was 2.1 in favor of male.The most observed type of psoriasis in the present study was psoriasis vulgaris (98.3％).The average psoriasis area and severity index (PASI) for patients were 9.47 ±7.63.Comorbidity was combined in 20.2％ cases.Patients with EOP had a significantly higher likelihood of family history of disease.Compared EOP to LOP,LOP had a significantly higher likelihood of comorbidities involvement (P ＜ 0.05) and significant higher BMI index (P ＜ 0.05).Conclusions The present study supports the hypothesis that there are clinical differences between EOP and LOP in Chinese population.Both dermatologists and patients should pay more attention to psoriasis-associated features,such as family history and comorbidity diseases involvements.

Objective To assess the association of subclinical thyroid dysfunction with fractures. Methods Medline, Embase, Pubmed, Cochrane Library, CBM, CNKI, Wan Fang, and VIP databases were systematically searched from January 1990 to August 2015 to identify prospective cohort studies which have studied the risk of fracture in patients with subclinical thyroid dysfunction. The relative risks ( RR) of cohort studies were pooled respectively, depending on the result of heterogeneity test among the individual studies search. The Stata (version 13. 0) software was used for meta-analysis. Results Nine prospective cohort studies including 292460 participants were identified as eligible for the meta-analysis. RR of subclinical hyperthyroidism for fracture was 1. 39(95%CI 1. 24-1. 55);for hip fracture, RR was 1. 24(95%CI 1. 10-1. 40);for nonspine fracture, RR was 1. 32 (95%CI 1. 09-1. 60). Different gender for subclinical hyperthyroid was associated with higher fracture rates:for females, RR was 1. 15(95%CI 1. 04-1. 27); for males, RR was 1. 31 (95% CI 1. 08-1. 59). The incidence of fracture in patients with subclinical hyperthyroidism was higher during the follow-up. For subclinical hypothyroidism, the RR was 1. 21(95% CI 1. 03-1. 42). Subgroup analysis indicated that there were significant differences between endogenous/exogenous subclinical hyperthyroidism and euthyroid, but no differences between endogenous/exogenous subclinical hypothyroidism and euthyroid were found. Conclusion Subclinical hyperthyroidism is associated with an increased risk of fracture in the population, especially hip fracture and nonspine fracture. During the course of subclinical hyperthyroidism, the incidences of fracture should be noticed both in females and males. However, there is no evidence which could prove a definite association between subclinical hypothyroidism and the risk of fracture.

Objective To evaluate the regulatory effect of OX40 co-stimulatory signal on the expression of Foxp3 in inductive regulatory T cells (iTreg) in vitro.Method CD4+ CD25+ naive T cells were isolated from C57BL/6 mouse lymphocyte suspension by MASC CD4+ CD25+ regulatory T cell isolation kit.Inductive Tregs were generated by stimulation of naive T cells in the presence of transforming growth factor beta (TGFβ1),anti-CD3,anti-CD28 and IL-2.The regulatory effect on iTregs was shown by use of OX40 stimulation monoclonal antibody (OX86) or control antibody.Using flow cytometric analysis (FACS),we examined the antibody-based identification of Tregs surface markers CD4 and CD25,along with the intracellular activation marker FoxP3.Results The ratio of CD4+ CD25+ nTregs isolated from mouse lymphatic node was (5.0 ± 0.4)％ vs.(71.8 ± 13.4)％ of TGFβ1-driven iTregs.The ratio of CD4+ CD25+ Tregs was (80.0 ± 1.6) ％ in OX40 stimulation McAb group vs.(86.0 ± 1.4)％ in control antibody group.Furthermore,the expression of Foxp3 was (59.2 ± 0.7) ％ in OX40 stimulation McAb group vs.(70.0 ± 0.8) ％ in control antibody group (P＜0.05).Conclusion TGFβ1-dependent protocol may induce the conversion of naive CD4+ T cells into CD25+ Foxp3+ iTregs.OX40 stimulation can down-regulate the expression of Foxp3 in CD4+ CD25 + iTreg significantly.Thus OX40 molecular may become an attractive target in Tregs-induced transplant tolerance.Further study should be performed to increase the suppressive activity of iTregs through blockade of OX40 signal.

A new wood-degrading fungus Monodictys asperospera(Cooke & Massee) Ellis with a high level of laccase production was chosen to study.This laccase was purified by ammonium sulfate precipitation,DEAE-cellulose and sephacryl S-300.Purification of about 8.1 fold was achieved with an overall yield of 5.7%.Its molecular weight was estimated to be about 77 kD.The optimum temperature and pH of the lac-case activity were 55?C and 6.0,respectively.Kinetic studies of the laccase showed that the Km and the Vmax for using syringaldazine as substrate was 0.163 mmol/L and 0.194 mmol/(L.min),respectively.The carbo-hydrate content was 18.14%.In addition,it was found that laccase activity was significantly inhibited by Cu2+.

Objective In order to master the current situation of Keshan disease in Yunnan province and to provide scientific basis for Keshan disease control and prevention. Methods Eighteen villages were selected as the investigation sites in 6 counties across all the Keshan disease wards in Yunnan province,where the residents were investigated. Then,the villages census data was collected,clinical examination aiming mainly on cardiovascular system was carried out,including electrocardiography and X-ray to the suspected patients. Correct diagnose of Keshan disease was made by the Diagnostic Standard of Keshan Disease(GB 17021-1997). At the same time,10 food samples and 10 hair samples for detecting selenium content in every investigation site. Results There were 9818 residents investigated in the 18 investigation sites in 6 counties,and 34 eases of Keshan disease were found,the total incidence rate was 0.35%(34/9818). Among the 34 Keshan disease eases,32 cases were latent Keshan disease,the incidence rate was 0.33%(32/9818); 2 cases were chronic Keshan disease,the incidence rate was 0.02%(2/9818). There was no any acute and sub acute cases be found. Most Keshan disease cases aged from 5 to 14,67.65% (23/34). Abnormal ECG rate was 6.90% (677/9818). Among 56 X-ray films,47 cases had a cardiothoracic ratio less than or equal to 0.50,83.93%(47/56),5 cases from 0.51 to 0.55,8.93%(5/56),4 cases from 0.56 to 0.60,7.14%(4/56). Selenium content was detected in 180 food samples and 180 hair samples. The average food selenium content (mg/kg) was 0.013±0.010,the lowest content in Yongsheng county (0.006± 0.001),the highest content in Tonghai county(0.027±0.009). The average hair selenium eontentwas(0.252± 0.078)mg/kg,with the lowest(0.145±0.043)mg/kg in Yoagsbeng county,the highest (0.297±0.062)mg/kg in Tonghai county. Conclusions The detected ratio of Keshan disease is low in Yunnan province. Most of Keshan disease patients age from 5 to 14. It was presented that the Keshan disease infectious agents were still strong and active. The foodstuffs and hair Selenium content is low in food and hair sample,and varies in different investigation site. It is necessary to supply selenium for prevent Keshan disease in the severe areas.

Objective To study the current incidence of Keshan disease in Yunnan Province,and provide scientific basis for Keshan disease(KD) prevention and control. Methods Based on the Scheme of KD Surveillance, 16 villages in 11 counties were chosen as surveillance sites by the historical data. An survey was made to the residents in the 16 surveillance sites by filling in the questionnaire, inquiry medical history, clinical examination, electrocardiogram and 2 meters post-anterior chest X-ray for suspected cases. KD cases were diagnosed according to the Diagnostic Criteria for Keshan Disease(GB 17021-1997). The prevalence data of KD in the whole province were collected from the KD case report in 2007 and the trace surveys. Results There were 6877 residents in 16 surveillance sites of 11 surveillance counties and totally 39 KD cases were diagnosed with a detection ratio of 0.57% (39/6877). The detection ratio of latent and chronic KD were 0.41%(28/6877) and 0.16%(11/6877), respectively and no acute or subacute cases were found. The cases aged 5 to 14 years old accounting for 66.67% (26/39). Electrocardiogram examination of 6877 residents were made and 5.25% (361/6877) abnormal electrocardiograms were detected in the 16 surveillance sites. Fifty-five people were checked by chest X-ray and there were 31 cases with heart-chest ratio ≤0.50, 16 cases with heart-chest ratio from 0.51 to 0.55 and 8 cases with heart-chest ratio from 0.56 to 0.60. The prevalence rate and incidence rate of chronic KD were 4.24 per 100 000 and 0.50 per 100 000 in Yunnan. No acute or subacute cases were found and the latent cases were listed. The prevalence rate and incidence rate were 7.76 per 100 000 and 1.18 per 100 000 in the 16 surveillance sites. Conclusions The incidence of KD is low incidence in Yunnan Province. Higher ineidence of chronic KD was detected in the some areas and the corresponding control measures need to be adopted.

Patients with hypoxia pulmonary hypertension (HPH) are often accompanied by dyspnea, fatigue, and headache. With the development of the disease, the right ventricle gradually collapses and eventually leads to death. Hypoxic pulmonary vascular remodeling is an important pathological basis of HPH, and the remodeled pulmonary vessels will form permanent thickening. The mechanism of hypoxic pulmonary vascular remodeling is relatively complex. At present, there are few studies on drugs for pulmonary vascular remodeling on the market, mainly focusing on the alleviation of pulmonary vasoconstriction. It was found that hypoxia induces calcium overload in pulmonary artery smooth muscle cells (PASMCs), resulting in the proliferation of PASMCs. The main mechanisms include: ① abnormal expression of calcium pumps; ② abnormal calcium channels in the plasma membrane of pulmonary artery smooth muscle cells; ③ overexpression of calcium-sensitive receptors in cells; ④ the expression of Na⁺/Ca²⁺ exchanger type-1 was abnormal. This review summarized several mechanisms of hypoxia induced calcium overload leading to pulmonary artery remodeling, hoping to provide a new idea for the treatment of HPH.
