Objective To evaluate the value of the peripheral capillary fasting plasma glucose examined by glucometer on screening of type 2 diabetes.Methods With the proportion stratified group sampling,all residents aged 15-75 years in Wuqing district were selected and detected on their capillary fasting plasma glucose(CFPG) by clucometer,and those whose CFPG was higher than 5.0mmol/L should have a 2-hour postprandial glucose(2 h PG) test.Data were analyzed by SPSS 11.5 software.Results The detection rates of diabetes,impaired glucose tolerance and impaired fasting blood glucose were 42.83%,27.88% and 3.74%,respectively.Making two ROC curve with test variable(FPG) and state variables(2 h PG≥11.1 mmol/L and 7.8 mmol/L≤2 h PG≤11.0 mmol/L),the areas under the curve were 0.862 and 0.405,respectively.Conclusion It is suggested to use the sensitivity standard that nears to 99% FPG≥5.0 mmol/L to screen diabetes.

Parkinson's disease (PD) is a neurodegenerative disease commonly found in middle-aged and elderly people,and its onset is attributable to both genetic and environmental factors. The gene mutation and oxidative damage of DJ-1 correlate with familial and sporadic PD,respectively. The mechanisms by which DJ-1 gene mutation and oxidative damage lead to PD include oxidative stress,mitochondrial dysfunction and proteasome dysfunction.Furthermore,DJ-1 is a biomarker of sporadic PD and it may become a new potential target of anti-PD drugs.

Objective To determine the risk factors for coronary artery lesions (CALs) in patients with Kawasaki disease (KD).Methods The clinical records of 2331 patients with KD from January 2005 to December 2014 in Beijing Children's Hospital,Capital Medical University were retrospectively analyzed.The relationship between the following factors and CALs was analyzed by univariate and multivariable Logistic regression analysis:age,gender,incomplete KD,total fever duration,intravenous immunoglobulin(IVIG) treatment resistance,white blood cell count,C-reactive protein (CRP),platelet count,sodium and albumin.Results The incidence of CALs was 36.0%(840/2331 cases).Univariate Logistic regression analysis indicated that male patients,incomplete KD,total fever duration ≥10days,IVIG treatment resistance,CRP>100mg/L,platelet count>300×109/L and albumin<35 g/L were associated with CALs (all P<0.05).Multivariable Logistic regression analysis identified that male patients (OR=1.698,95% CI 1.383-2.084,P<0.001),incomplete KD (OR=2.730,95% CI 2.121-3.515,P<0.001),total fever duration ≥10 days (OR=2.556,95% CI 1.975-3.307,P<0.001),CRP>100 mg/L (OR=1.556,95% CI 1.274-1.900,P<0.001) and albumin<35 g/L (OR=1.665,95% CI 1.323-2.096,P<0.001) were the independent risk factors for CALs.Conclusions The main damage in patients with KD is CALs.The male children with KD,incomplete KD,total fever duration ≥10 days,CRP>100 mg/L and albumin<35 g/L were prone to CALs.

Objective:To evaluate the effects of Er,Cr:YSGG laser on the root surface of periodontally involved teeth and healthy teeth,concerning the microstructure and the roughness.Methods:Eight freshly extracted teeth due to severe periodontitis and eight freshly extracted teeth due to orthodontic rea-sons or being third molar were chosen in this study.The root surface of each tooth was divided into four areas,and received four treatment methods:no treatment (control group );root planing with Gracey scaler for 30 seconds;irradiation by the lower power Er,Cr:YSGG laser;irradiation by the higher power Er,Cr:YSGG laser.Four periodontally involved teeth and four healthy teeth were used for the evaluation of microstructure using scanning electron microscope (SEM).The other four periodontitis teeth and four healthy teeth were used for the evaluation of roughness (Ra value )using 3 D profiler.Results:Smear layer was found on the teeth scaled by Gracey scaler,while the teeth irradiated by Er,Cr:YSGG laser demonstrated a melting surface with less smear layer.In the periodontitis teeth irradiated by the higher power,opening dentinal tubules could be observed.For the periodontally involved teeth,the Ra values of groups 1 to 4 were (237.4 ±20.0)nm,(1 35.7 ±1 1 .9)nm (P=0.01 ),(463.6 ±49.3)nm (P<0.001 )and (486.0 ±59.0)nm (P<0.001 )respectively.For the healthy teeth,the Ra values of groups 1 to 4 were (1 91 .4 ±44.5)nm,(1 31 .6 ±21 .5)nm (P=0.482),(463.7 ±34.6)nm (P<0.001 )and (470.3 ±1 21 .3)nm (P<0.001 )respectively.Conclusion:Er,Cr:YSGG laser can affect the microstructure of the cementum of the periodontitis teeth and healthy teeth.Irradiation by the Er,Cr:YSGG laser resulted in a melting surface with less smear layer and increased the roughness in the surface of root.

Objective To investigate the clinical characteristics of skin lesions of tsutsugamushi disease.Methods The skin lesions and clinical characteristics of 17 hospitalized patients with tsutsugamushi disease were analyzed. Results Of the patients, 88.2% (15/17) developed eschar and skin ulcer, 64.7% (11/17) had skin rashes. The patients often developed solitary, painless and nonpruritic eschar 4 to 10 days after the occurrence of fever, with indefinite locations and average diameter of 1.2 cm (range: 0.5 - 3.0 cm). The eschar was covered with a black and dry surface and surrounded by a ring-shaped erythematous halo, and usually shedded 5 to 9 days after the appearance with the formation of shallow ulcer. Superficial lymphadenectasis was observed near the eschar in 80% of the patients with eschar, and no eschar was observed at the first visit in 66.7% of the patients. Skin rashes mainly included nonpruritic congestive papules (45.5%) and maculopapular rashes (54.5%), and often subsided 2 to 5 days after emergence. Conclusions The skin lesions of tsutsugamushi disease include eschar and skin rashes. Eschar is an important characteristic and highly suggestive of this entity.

Objective To discuss the role of interleukin (IL)-12 in capillary bronchiolitis disease.Methods Fifty-nine cases of capillary bronchiolitis children under 2 years old were enrolled as the bronchiolitis group Ⅰ(n =28) and bronchiolitis group Ⅱ(n =31),36 cases of children with bronchopneumonia of the same age and 31 cases of children suffered from non-infectious diseases such as hernia and renal calculus of the same age were enrolled as bronchopneumonia control group and normal control group respectively.The peripheral blood IL-12 levels of four groups were detected by enzyme-linked immunosorbent assay.Results The levels of the peripheral blood IL-12 in bronchiolitis group Ⅰ,bronchiolitis group Ⅱ,bronchopneumonia control group and normal control group were (34.72±7.96) pg/ml,(55.30 ±6.72) pg/ml,(56.79±10.36) pg/ml and (61.23 ± 11.51) pg/ml respectively.The level of the peripheral blood IL-12 in bronchiolitis group I was significantly lower than that in bronchiolitis group Ⅱ,bronchopneumonia control group and normal control group respectively (P <0.05),and the level of the peripheral blood IL-12 in bronchiolitis group ⅡⅡ was significantly lower than that in bronchopneumonia control group and normal control group respectively (P < 0.05),but there was no significant difference between bronchopneumonia control group and normal control group (P > 0.05).Conclusion The level of IL-12 is one of the important factors for bronchiolitis disease,the reducing of serum level of IL-12 in children who have a high risk factor of capillary bronchiolitis is more obvious.

Aim The goal is to make a further comprehension of the pathogenesis of Parkinsons disease (PD) and hence add further knowledge for PD diagnosis by observing the functions of nitric oxide (NO) in striatum (STR). Method Microelectrodes were used to observe the effects of sodium nitroprusside (SNP), L-glutamic acid (GLU) and ?-aminobutyric acid (GABA) on STR neurons' spontaneous firing rates, and at the same time, we observed the effects of NO on GLU and GABA. Results 77% (51/66) of the tested neurons were excited by SNP, NO synthase inhibitor L-NAME antagonized the excitatory effect of SNP. Duringthe periods of microelectrophoresis GLU and GABA, SNP amplified the excitatory effect of GLU and weakened the inhibitory effect of GABA. L-NAME antagonized the excitatory effect of GLU.Conclusion These results demonstrated clearly that NO, GLU and GABA functions might converge in the same STR neurons. NO and GLU functions are excitatory whereas GABA function is inhibitory on the firing activities in STR neurons.
