Objective To explore the advantage of the mini-incision doubling eyelid operation comparied with buried suture method.Methods 201 single eyelid cases were randomly divided into 2 groups:group A(101 cases)using mini-incision doubling eyelid operation,and group B(100 cases)using the double eyelid plasty with buried suture.Their effect was comparied.Results 157 cases were received postoperative follow-up.Group A(81 cases)contained 45 thin eyelids and 36 thick eyelids.Group B(76cases)included 32 thin eyelids and 44 thick eyelids.The postoperative follow-up for 1 month revealed that there was no statistically significant difference in the rate of satisfaction between group A and group B among the thin eyelid patients(P＞0.05).But statistic difference was found between A and B group among the thick eyelid patients(P＜0.05).The follow-up period for group A and group B was in the range of 2.5 to 3.5 years.The maintenance-well rate between the thin eyelid and the thick eyelid patients in both groups was significantly different(P＜0.05).Conclusion The mini-incision doubling eyelid operation is superior to the double eyelid plasty with buried suture in the rate of postoperative satisfaction and long-term effect.It is deserved to have more applications.

Objective investigate the correlation between plasma soluble receptor for advanced glycation endproducts (sRAGE) and arterial stiffness in patients with different types of metabolic syndrome (MS).Methods A total of 180 subjects were drawn from a epidemiologic follow-up study,including 60 cases non-metabolic syndrome (NMS),60 cases metabolic syndrome without diabetes mellitus (NDMMS),60 cases metabolic syndrome with diabetes mellitus (DMMS).Carotid femoral arterial pulse wave velocity (CFPWV) was assessed by the French KangPuLe atherosclerosis measurement instrument,and plasma sRAGE levels were measured by ELISA.Comparison of mean in multiple groups was conducted by analysis of variance.Multivariate analysis was done with multiple linear stepwise regression analysis.P ＜ 0.05 was considered as statistically significant difference.Results Compared with NMS group,plasma sRAGE levels were significantly lower in DMMS and NDMMS groups [(635.07 ± 229.20) pg/mL vs.(671.17 ± 358.16) pg/mL vs.(992.99 ± 427.83) pg/mL,P =0.001].CFPWV of DMMS group was significantly higher than that of NMDMS and NMS groups (14.22 ±3.14) m/s vs.(12.15 ±2.79) m/s vs.(11.66 ± 2.52) m/s,P =0.002).Plasma sRAGE level was negatively correlated with CFPWV (r =-0.278,P =0.005).(3) Multiple linear regression analysis demonstrated that age (β =-0.091,95％ CI-0.096 ～-0.095,P =0.031),HDL-C (β =1.295,95％ CI 1.231 ～ 1.360,P =0.022) and sRAGE (β =0.119,95％ CI 0.118 ～ 0.130,P =0.032) had a significant effect on CFPWV.Conclusions The increased arterial stiffness is closely related to the discreased plasma sRAGE levels in MS.Plasma sRAGE maybe a novel target for vascular disease prevention and treatment in patients with metabolic syndrome.

AIM:To study the correlation of serum uric acid ( UA) level with carotid plaques and arterial stiff-ness in the patients with essential hypertension ( EH) , and to explore the predictive value of serum UA for evaluating EH preclinically .METHODS:A total of 92 patients with EH and 30 healthy individuals were enrolled .The value of UA and other indicators were detected .B-mode ultrasound examination was performed to measure the common carotid artery intima -media thickness ( IMT) and the sites of plaque in the internal carotid-artery, external carotid artery and carotid bifurca-tions.Carotid-femoral arterial pulse wave velocity ( CFPWV) was assessed by Complior?atherosclerosis measurement in-strument.RESULTS:The serum level of UA in the patients with EH was higher than that in control group [(361.51 ± 83.81) μmol/L vs (317.03 ±62.22) μmol/L, P<0.05].The mean value and abnormal rate of IMT between hyperten-sion group and control group were significant difference [(0.69 ±0.14) mm vs (0.60 ±0.12) mm, 42.39%vs 10.00%, P<0.05].In 92 EH patients, 45 cases had carotid plaques .These 45 cases were divided into 3 groups according to the plaque severity, among which the serum UA level had statistically significant differences [(285.25 ±78.41) μmol/L, (341.19 ±63.99) μmol/L and (401.33 ±88.49) μmol/L, P<0.05].Compared with rigid plaque group ( n=34), the serum UA level in soft plaque group (n=11) was significantly higher [(389.00 ±69.45) μmol/L vs (323.03 ± 72.71) μmol/L, P<0.05].A stepwise multiple linear regression analysis demonstrated that age ( r=0.414), systolic blood pressure (r=0.224), pulse pressure (r=0.270) and uric acid (r=0.219) were predisposed factors for higher CFP-WV (P<0.05).CONCLUSION:UA is one of the risk factors causing hypertension .Serum UA level may reflect the sever-ity and stability of carotid plaques .The increased arterial stiffness is closely related to the increased serum UA level in EH .

Objective To investigate the distribution of water-borne fluoride and the current status of water defluoridation project by improving drinking water quality in endemic fluorosis areas in Shandong province,and to provide scientific basis for making strategies in prevention and control of the disease. Methods According to "the National Technical Scheme for Endemic Disease Control in 2004, 2005 and 2006", 113 endemic fluorosis diseased counties(cities, and districts) of the province's 17 cities were screened in order to investigate the fluoride level in drinking water in fluorosis villages, recheck the fluoride level after implementing the water defluoridation project, and investigate the current status of the water defluoridation project. The fluoride level in drinking water was determined by F-ion selective electrode. Results There were a total of 5816 water defluoridation projects in the province. Most of them were carried out by drilling a deep well to get under-ground water. The wells still in good condition were accounted for 72.80% (4234/5816). Intermittent operated wells were accounted for 3.11% (181/5816). Abandoned wells were accounted for 24.09%(1401/5816). Level of water fluoride was determined in 6940samples from fluorosis villages(villages that not carry out the water defluoridation project as well as villages carried out the water defluoridation project with abandoned wells were included) and the value that lower or equal to 1.00mg/L was determined in 2987 villages which accounted for 43.04% (2987/6940). Level of water fluoride that over 1.00 mg/L was found in 3953 villages which accounted for 56.96% (3593/6940), and the highest level of water fluoride was 11.33 mg/L. Level of water fluoride were determined in 4415 samples from water defluoridation project and the value lower or equal to 1.00 mg/L was in 2983 wells which accounted for 65.53%(2983/4415). The value over 1.00 mg/L was in 1522 wells which accounted for 34.47%(1522/4415), the highest value of water fluoride was 9.71 mg/L. Conclusions Level of water fluoride in up to 1/2 of the villages and 1/3 of the projects, is still higher than the standard in Shandong province. Nearly 1/4 of the project has been abandoned. The current situation for endemic fluorosis control is still not good in the province, countermeasures for endemic fluorosis must be carried out as soon as possible and surveillance of water defluoridation project must be strengthened.
