Objective To explore the correlation between serum homocysteine (Hcy) level and diabetes mellitus combined with cerebral infarction (DMCI) in patients. Methods A total of 144 patients with type 2 diabetes mellitus (T2DM) were selected and divided into two groups, patients without cerebral infaction (group A, n=64) and patients with cerebral infaction (group B, n=80). Thirty healthy people were used as control group (group C). The serum Hcy level was detected by enzymatic cycling assay in three groups. The serum levels of cholesterol (TC) and triglyceride cholesterol (TG) were detected by enzymatic determination. The serum levels of high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were detected by homogeneous phase method. The serum level of creatinine (Cr) was detected by creatine oxidase method. The level of uric acid (UA) was detected by urinary enzyme peroxidase coupling method. Glycosylated hemoglobin (HbA1c) was detected by high performance liquid chromatography. The carotid artery intima media thickness (IMT) was examined by color Doppler ultrasound, and patients were divided into mild and no stenosis group, moderate stenosis group and severe stenosis group according to the
results. The levels of Hcy were compared between all groups. The correlation of Hcy level and other indicators was analyzed. Results The levels of Hcy and HbA1c were group C0.05). There were no significant differences in UA and Cr levels between the three groups (P>0.05). The level of Hcy was positively correlated with age (rs=0.411), HbA1c (rs=0.219) and Cr (rs=0.242), and negatively correlated with gender (rs=-0.202) and HDL-C (rs=-0.278, P<0.05). There were no significant correlation between Hcy level and other variables (P>0.05). With the increased degree of carotid artery stenosis, the Hcy level and the proportion of HHcy showed a rising trend in patients (P<0.01). The level of Hcy was positively correlated with IMT(rs=0.781, P<0.001). Conclusion Hcy is a risk factor for the onset of DMCI. The high level of Hcy is closely related to the occurrence and progression of atherosclerosis. Hcy has great value for early screening and prevention of DMCI.

Clinical epidemiological studies have shown that vitamin D deficiency is associated with infectious diseases, which is confirmed by recent studies implying the role of vitamin D as a key regulator of host defense against infections. Bioactive vitamin D triggers antimicrobial pathways against pathogens in mucous membrane and cells of the human innate immune system. In addition, vitamin D also attenuates excessive inflammation and acquired immunity, and thus limits collateral tissue damage. The observed effects of vitamin D on infectious diseases, particularly airway infections, should be addressed in the management of viral infections. Findings from cross-sectional studies should be confirmed by prospective research. In this review, we summarize the current knowledge regarding the effect of vitamin D on innate and acquired host defense against infections.

Objective To investigate the effects of losing ratio of orthodontic brackets bonding after prolonged etching time (prolonged etching time method) and microabrasion with normal acid etching time (etching after microabrasion method) to different degree of dental fluorosis.Methods A total of 30 patients with dental fluorosis were selected from the cases treated in the Department of Stomatology,Lianyungang Hospital of Traditional Chinese Medicine.They were classified as 3 groups from mild to severe degree according to Dean's criteria,10 people per group.Patients within each group were randomly assigned to 2 subgroups,5 people per subgroup;prolonged etching time method and etching after microabrasion method were used,respectively,in each subgroup.The total and first losing ratios of brackets at five time points (1,2,4,12 and 24 weeks) were observed.The losing ratio differences of orthodontic brackets between the two disposing measures bonding to different degree of dental fluorosis were analyzed.Resuts The total bracket loss rates were 38.3％ (46/120) and 21.4％ (25/117),respectively,in severe dental fluorosis disposed by prolonged etching time method and etching after microabrasion method.It was significantly higher than that of the same processing method of mild and moderate dental fluorosis groups,in which the total bracket loss rates were 12.5％ (15/120),18.1％ (21/116),7.6％ (9/118) and 5.8％ (7/120),respectively,and the differences were statistically significant (x2 =21.12,11.87,8.96,12.24,all P ＜ 0.01).The total loss rate of etching after microabrasion method was lower than that of prolonged etching time method in mild dental fluorosis group,the difference was not statistically significant (x2 =1.56,P ＞ 0.05).The total loss rates of etching after microabrasion method were lower than that of prolonged etching time method in moderate and severe dental fluorosis groups,and the differences were statistically significant (x2 =8.49,8.13,all P ＜ 0.05).The medians of first bracket loss rates were 8.3％ and 4.3％,respectively,in severe dental fluorosis disposed by prolonged etching time method and etching after microabrasion method.They were significantly higher than that of the same processing method of mild and moderate dental fluorosis groups,in which the medians of first bracket loss rates were 2.5％,4.3％,1.7％ and 0.8％,respectively,and the differences were statistically significant (U =2.619,2.627,2.312,2.627,all P ＜ 0.05).The average percentage of first bracket loss rates of etching after microabrasion method was lower than that of prolonged etching time method in mild dental fluorosis group,the difference was not statistically significant (U =-0.949,P ＞ 0.05).The average percentages of first bracket loss rates of etching after microabrasion method were lower than those of prolonged etching time method in moderate and severe dental fluorosis groups,and the differences were statistically significant (U =-2.214,-2.410,all P＜ 0.05).Conclusions Whether in prolonged etching time method subgroup or etching after microabrasion method subgroup,the more serious injury of dental fluorosis is,the higher loss rate of orthodontic bracket will be.For the clinical treatment of mild and severe dental fluorosis,the effect of etching after microabrasion method is better than prolonging etching time method.

Objective To investigate the surgical treatment of Maisonneuve injury associated with posterior malleolus fracture under direct visualization via the posterolateral approach.Methods Between January 2008 and June 2015,27 patients with Maisonneuve injury associated with posterior malleolus fracture were treated at our department.They were 18 men and 9 women,aged from 20 to 60 years (average,40.1 years).All fractures and syndesmoses received open reduction under direct visualization and internal fixation via the posterolateral approach.The posterior malleolus fractures were fixed with screws or plate and the syndesmoses fixed using cortical bone screws.Functional results were evaluated using the Baird-Jackson ankle scoring system.Results The patients were followed up for 8 to 30 months (average,18 months).No wound infection,necrosis,dehiscence,lose of reduction or implant failure was found during follow-up visits.All cases got bony union at the last visit.The excellent and good rate was 92.6％.Conclusion Since the posterolateral approach allows good access to the Maisonneuve injury and posterior malleolus fracture under direct visualization,it facilitates accurate direct fracture reduction,stable fixation and early exercise.

Objective To study the correlation between ?-fibrinogen gene variation (-455G/A) and plasma fibrinogen level and cerebral infarction.Methods 86 hypertension patients with cerebral infarction(infarction group),85 hypertension patients without cerebral infarction(hypertension group) and 90 healthy people(control group) were enrolled in this trial. The polymorphism of ?-fibrinogen gene-455G/A located at the start of transcription from all subjects was analyzed by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) technique. Plasma fibrinogen level was measured with prothrombin time (PT) assay.Results The fibrinogen level in infarction group(4.82?0.26 g/L) was significantly higher than that in control group(4.37?0.19 g/L)( P 0.05).The A-455 allele frequency in infarction group was significantly higher than those in control group and hypertension group (all P 0.05). Conclusion Plasma fibrinogen level is affected by the ?-fibrinogen gene -455G/A polymorphism. The fibrinogen A-455 allele may be an independent risk factor of cerebral infarction.
