One hundred and four patients aged of 65 years or above with cardiocerebral vascular diseases admitted from March to September 2008 were enrolled in the study. The fast plasma glucose (FPG) and 2 hours postprandial blood glucose (2 hPG) were tested. For patients with undiagnosed diabetes, if FPG≥7.0 mmol/L, 2 hPG≥11.1 mmol/L, their blood sugar index was checked again; if 2hPG was 7.8 mmol/L to 11.1 mmol/L, FPG from 6.1 mmol/L to 7.0 mmol/L, Oral glucose tolerance test (OGTT) was performed. Among the 104 patients, 30 cases of diabetes were diagnosed previously accounting for 28.8 %; 7 cases were newly diagnosed accounting for 6.8%; 21 cases were diagnosed as impaired glucose regulation accounting for 20.2%, with a total rate of sugar metabolism abnormality of 55.8%. The results indicate that blood glucose index should be regularly checked for elderly patients with cardiocerebral vascular diseases.

OBJECTIVETo explore the surgical method and its clinical effects of minimally invasive osteosynthesis on the treatment of complex ankle fractures.

METHODSFrom January 2007 to December 2011, 53 patients with complex ankle fractures were treated with minimally invasive osteosynthesis. There were 31 males and 22 females, with an average age of 38.2 years old (ranged, 18 to 65). According to the system of Lauge-Hansen, 32 fractures were supination external rotation injury (grade WV), 13 fractures were pronation external rotation (grade III or IV), 5 fractures were pronation abduction (grade III); and 3 fractures can not be classified due to serious comminution fracture of fibula. According to the system of Denis-Weber, there were 4 cases with type A, 34 cases with type B and 15 cases with type C. Seven cases were open fractures. The duration from injuries to operation ranged from 2 hours to 14 days with an average of 5 days. The sequence of reduction and fixation of ankle fractures was firstly posterior malleolus, then medial malleolus and lateral malleolus, and inferior tibiofibular syndesmosis lastly. The fractures of posterior malleolus were reduced and fixed through anterior ankle approaches; the fractures of medial and lateral malleolus were percutaneously fixed with bolts or blade plate or tensile force band; and inferior tibiofibular syndesmosis were firmly fixed if necessary. Baird-Jackson scoring system was used to evaluate clinical effects.

RESULTSForty-eight patients were followed up from 10 to 36 months with an average of 13 months. The fractures got healing with an average time of 12 weeks (ranged, 10 to 18). According to the Baird-Jackson scoring system, the mean score of ankle function was 94.7 +/- 4.2, and 28 cases obtained excellent results, 15 good, 3 fair and 2 poor. One case experienced superficial infections and was cured by changing dressings, 2 cases experienced fixed syndesmosis screw breakage.

CONCLUSIONThe surgical method of minimally invasive osteosynthesis can ensure the anatomical join restoration, protect the blood supply of fracture end, rebuild the function of ankle joint, obtain satisfactory clinical results in treating complex ankle fractures.

Plant samples were collected and investigated periodically. According to the growth of different parts and the characteristics of dry substance accumulation of Scrophularia ningpoensis, the development of S. ningpoensis could be divided into four stages: seeding stage, stem and leaf growth stage, expanding period of root tubers, and dry substance accumulation stage of root tuber. Leaf numbers of S. ningpoensis grew gradually from one at first to 370 at the final stage, main stem leaf were 50 pieces. Leaf size increasesed with the fastest growth at the stem and leaf growth stage, average daily increase amount was 225 cm2. By the middle of August, leaf size reached to 16,270 cm2. Leaf area indexrose sharply in the seeding stage, and remained above 8 among stem and leaf growth stage and expanding period of root tubers, and rapidly reduced to zero in the stage of dry substance accumulation of root tuber. Leaf area ratio has a tendency of obvious dropping. The net assimilation rate had a small change ranges, two small peak were seeding stage and dry substance accumulation of root tuber. The value of specific leaf area was higher in seeding stage, and in the earlier stage of dry substance accumulation of root tuber. Relative growth rate changed with large ranges, higher in seeding stage, rapid decrease in stem and leaf growth stage, rose in expanding period of root tubers, and declined again in the stage of dry substance accumulation of root tuber. Crop growth rate was higher in the first and last stages, and smaller in interim stage. The growth parameters of S. ningpoensis such as relative growth rate, net assimilation rate, leaf area index, leaf area ratio, specific leaf area, crop growth rate changed along with the growth. The rule of dry matter accumulation was as follows: the dry matter increased slowly during the seeding stage and speeded up in the middle and late stages, and in dry substance accumulation of root tuber increased slower, the growth of dry matter all appeared an "S" curve, and accorded with logistic equation. Cultivation technologies of S. ningpoensis and the relevant management methods could be established according to the growth of different parts of S. ningpoensis and the characteristics of dry substance accumulation in different stage.

AIM:To observe the pathological changes of the lower segment of nasolacrimal duct mucosa in rabbits at different stages after retrograde lachrymal dilated drainage tube implantation.
METHODS:Totally 14 New Zealand rabbits were used in the present study. One side of nasolacrimal duct was obstructed to produce an experimental model and operated the reverse implantation of nasolacrimal duct intubation. Histological changes of the lower segment of nasolacrimal duct mucosa were observed by routine light microscope at 2, 4, 6, 8, 10, 12 and 14wk after the operation.
RESULTS: Compared with the control side, the group of 2 and 4wk after surgery presented the inflammatory cytokine. The group of 12wk after the operation presented isolated granuloma. Group 12 and 14wk presented scattered granuloma. The size of the granulomas was smaller and the density of epithelioid cell and fibroblast were lower in group 12wk than those in group 14wk by HE and Masson trichrome stain.
CONCLUSION:Recurrent Silicone Tube is used to treat nasolacrymal duct obstruction. Nasolacrimal duct can be narrowed and blocked again by granuloma, progressive fibrosis and adhesion of surrounding tissues when tube is in the duct more than 12wk.

Objective To explore the effect of fluoride and arsenic pollution on bone metabolism in exposed population. Methods One hundred and fifty-two fluoride and arsenic exposed people were selected from Jiaole village, Yuzhang town, Xingron county, Guizhou province in 2006, and 59 not exposed people from Daguoduo village 13 km away from Jiaole village were selected as control. Urinary fluorine(UF), urinary arsenic (UAs), urinary hydroxyproline (UHYP), cross-linked N-telopeptides of type I collagen (UNTX) and bone strength index(STI) were detected. Results The main effect of fluoride on UHYP and UNTX were statistically significant (F = 9.785, 4.225, P < 0.01 ), but was not significant on STI(F = 0.183, P > 0.05). The main effect of arsenic on UNTX was statistically significant (F = 2.660, P < 0.05 ), but was not significant on UHYP and STI(F = 2.012, 0.183,all P > 0.05). The interaction between fluoride and arsenic on UNTX was statistically significant (F= 2.429, P <0.01), but was not significant on UHYP and STI(F= 1.218, 1.001, all P> 0.05). Conclusions Fluoride exposure can affect the metabolism of collagen and bone resorption, and Arsenic exposure main affect bone resorption, fluoride and arsenic co-exposure have more significant effect on bone resorption. UNTX may be used as biological biomarker of bone metabolism for population co-exposed to fluoride and arsenic in health monitoring.
