The calibration curves of menthol was also obtained with a good linear relationship within the range of 0.234-1.17 μg (r 2=0.997 4), the average recovery was 97.0%. Conclusion The methord is simple and accurate. It can be used to control the quality of Keyou nanoemulsion.

Objective To investigate the relationship between the severity of diabetic retinopathy and serum bilirubin level. Methods From August 1 2008 to December 31 2009, hospitalized patients of 1062 cases with type 2 diabetes were divided into three groups according to fundus examination: no diabetic retinopathy (NDR) group (457 cases), non-proliferative diabetic retinopathy (NPDR) group (484 cases)and proliferative diabetic retinopathy (PDR) group ( 121 cases). The difference in serum bilirubin level was compared. Results Total bilirubin in PDR, NPDR and NDR group were (9.96 ± 3.84), ( 11.41 ± 3.82),( 13.38 ± 3.98) μ mol/L respectively. There was significant difference among three groups (P ＜ 0.01 ). Logistic multivariate regression analysis showed that a drop in serum total bilirubin level was an independent risk factor of diabetic retinopathy. Conclusions Bilirubin level and the severity of diabetic retinopathy have some relationship. The antioxidant bilirubin and anti-inflammatory effect should be paid attention to.

Objective:To study the influence of vitamin C ( VC) on dendritic cells ( DC) ,and detect DC maturation,to provide a feasible method and thought for quickly preparating DC vaccines.Methods:Collected the peripheral blood (about 50 ml) from healthy volunteers,and isolated peripheral blood mononuclear cells with lymphocyte separation medium and obtain DC.With stimulating with different concentrations of VC for (24 h),then washed with PBS,and set up blank control group (V0).The expression of DC surface co-stimulating molecules CD80/86 and HLA-DR, CD40 was detected by flow cytometry.By setting the concentration gradient and time gradient, exciting optimal concentration and stimulating time of VC on DC, and analyzed the reasons of VC promoting DC maturation.Results:VC could effectively stimulate DC,CD80/86 expression had significantly increased contrast to the blank control group (V0).And the experiments show that VC’s best stimulating concentration was 1 mmol/L,and on the third day,the CD80/86 expression rate of VC group was (78.6±4.6) %,and blank control group V0 was (34.1±5.7) %.DC surface HLA-DR expression:VC (56.8± 4.4) %,blank control group V0 (25.4 ±4.7) %,the difference between two groups was statistically significant,P<0.05.CD40 and CD40L expression and results show that VC 2.5 mmol/L group of CD40 expression rate up to (59.3±3.7) %,while V0 group was only (11.1 ±2.4) %,that illustrate VC could significantly regulate CD40 expression on DC surface,but CD40L not reflect.Fluorescence mi-croscope results showed that DC’ s antigen catching ability was also significantly promoted.Conclusion:VC can significantly regulate DC maturity,and may up regulate CD40,thus promoting the express of CD80/86 and HLA-DR.When the concentration is 1 mmol/L,VC expresses the strongest regulation function on DC.

Objective To investigate the type 2 diabetic patients with glomerular filtration rate and urinary albumin value as renal finction evaluation.Methods A total of 1217 patients with type 2 diabetic nephropathy from August 1,2010 to June 31,2012 were selected.Evaluated glomerular filtration rate (eGFR) was calculated according to the currently recommended simplified modification of diet in renal disease study (MDRD) formula.According to the K/DOQI guidelines for chronic kidney disease,patients were divided into three groups:group A [eGFR ≥90 ml/ (min ·1.73 m2)] of 891 cases,group B [60 ml/(min· 1.73 m2) ≤eGFR ＜ 90 ml/(min· 1.73 m2)] of 256 cases,group C[eGFR ＜ 60 ml/(min· 1.73 m2)]of 70 cases,respectively.Eight-hour urinary albumin excretion rate (UAER) was compared between and among the groups; according to 8-hour UAER,patients were divided into three groups:group a (8-hour UAER ＜20 μg/min) of 946 cases,group b (20 μg/min≤8-hour UAER ＜200 μg/min) of 193 cases,group c(8-hour UAER ≥ 200 μ g/min) of 78 cases.eGFR was calculated and compared between and among the groups.Results Eight-hour UAER was (32.71 + 79.62),(57.56 + 130.59),(107.50 + 222.64) μ g/min in group A,B,C,and the difference among three groups was statistically significant (P＜0.05).eGFR was (110.78 ±32.75),(108.26 ±45.78),(94.96 ±32.30) ml/ (min ·1.73 m2) in group a,b,c,and the difference between group a and group c,or between group b and group c was statistically significant (P ＜0.05),but the difference between group a and group b was not statistically significant (P ＞0.05).Conclusion When evaluating the function of type 2 diabetic nephropathy,two indicators should be considered:glomerular filtration rate and urinary albumin.

Objective To explore the efficiency of endoscopic septoplasty with submucous resection for the treatment of 220 patients with deviated nasal septum and report our experience in this field. Methods From May 2006 to May 2010, 220 patients with deviated nasal septum were treated by endoscopic septoplasty with submucous resection to decompress the stress points, resect the deviated parts and implant the reshaped bone of nasal septum, while retaining the normal structure of nasal septum with minimally invasive technique. Results Satisfactory effects were achieved in all the 220 patients, showing centered septal structure and disappeared symptoms such as nasal obstruction, headache and nasal hemorrhage, but no complications including perforation of nasal septum, depressed nasal bridge and septal chalasia and flaring. Conclusion Rhino-endoscopic septoplasty with submucous resection can substantially retain the original structure of nasal septum and thus is proven to be a desirable operation with multiple advantages including minimal invasiveness, quicker healing and fewer complications.

ObjectiveTo explore the value of simvastatin in improving endothelial function in the patients with acute coronary syndromes in shorter time.Methods60 patients with acute coronary syndrome(acute myocardial infarction and unstable angina/non-ST elevation myocardial infarction) were randomized to be treated with placebo(n=30) or simvastatin 20 mg daily(n=30) for 3～5 d.At the admission and endpoint,Brachial ultrasound was used to measure endothelium-dependent flow-mediated dilatation(FMD) and response to endothelium-independent nitroglycerin. ResultsFMD was unchanged with placebo,but increased with simvasatin,from(2.65±2.95)% to(4.19±2.59)%(P=0.027).Responses to nitroglycerin were similar during the time course of the study in the 2 groups.The improvement of FMD was not correlated with the level of TC(R2=0.081,P=0.37),LDL-C(R2=0.056,P=0.46) or HDL-C(R2=0.073,P=0.40).ConclusionSimvastatin initiated early after acute coronary syndromes rapidly improves endothelial function in short course.No correlation has been detected between the pharmacological effects of simvastatin with the fall in TC and LDL-C.
