Objective To study the relationship between peripheral blood hemoglobin (HB) and blood pres- sure.Methods We performed a cross-sectional analysis in 1153 subjects aged 29-83 years.Waist circumfer- ence,HB,blood pressure,high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL- C),triglycerides (TG),total cholesterol (TC) were determined.Results ①With the increasing of blood pres- sure,HB had a clearly increasing trend (HB,normotensive:137.5?14.7 vs prehypertension:143.4?14.4 vs hy- pertension:144.3?13.8 g/L,P

Lagerstroemia speciosa Pers,also known as banaba,belongs to Lythraceae and contains ursolic acid,corosolic ac?id,asiatic acid and 30 other kinds of effective components.It has multiple pharmacological activities,including hypoglycemic,hypo?lipidemic,anti-oxidant and anti-viral activities,and is mainly used for the treatment of obesity and diabetes in folk medcine.This re?view summarizes the recent advances in chemical composition and pharmacological effects of L.speciosa Pers,so as to provide the theo?retical basis and reference for its further research and application.

OBJECTIVETo observe a short-term clinical result of modified resin-bonded fixed partial denture(MRBFPD) utilizing tooth undercuts.

METHODSOne hundred and twenty-nine patients received restoration and totally 196 missing teeth were restored with 148 MRBFPD. According to the positions of abutments in the dental arch, all the MRBFPD were divided into three groups, namely anterior prostheses (40), posterior prostheses (95) and prostheses spanning anterior and posterior (13). The prostheses were examined at 2 weeks, 1 month, 3 months, 6 months, and every year after denture delivery. Retention and marginal integrity of MRBFPD, sensibility, secondary caries and gingival bleeding index were clinically evaluated. The evaluation results were graded as good, acceptable, and bad according to modified United States Public Health service (USPHS) criteria. Survival in this study was defined at two levels: "complete" survival (survival without any debonding), and "functional" survival (survival including loss of retention on one occasion and successful rebonding of the original MRBFPD without further debonding).

RESULTSThe average follow-up period was 26 months. Fifteen prostheses failed and were rated as bad with USPHS criteria, and ten prostheses were evaluated as "acceptable" because the gingival bleeding index has been rated as 3 or more at one appointment but reduced to 1 or 0 after treatment. The results of the other 123 prostheses were evaluated as "good". The "complete" survival rates were 80% (32/40) for anterior prostheses, 11/13 for prostheses spanning anterior and posterior, and 95% (90/95) for posterior prostheses, while the "functional" survival rates were 80% (32/40), 11/13 and 99% (93/95) respectively. The "complete" survival rate of posterior prostheses was statistically higher than that of anterior prostheses (χ(2) = 5.433, P < 0.05). The "functional" survival rate of posterior prostheses was not only higher than that of anterior prostheses (χ(2) = 13.179, P < 0.01)but also higher than that of prostheses spanning anterior and posterior (χ(2) = 4.143, P < 0.05) statistically.

CONCLUSIONSThe results of this preliminary study suggest that short term survival rate of MRBFPD in posterior area was statistically better than that in anterior area. The outstanding advantage of MRBFPD is the minimum need of dental tissue reduction. However, their long-term success needs further investigation.
