Chinese Journal of Tissue Engineering Research 2015;19(20):3152-3157
BACKGROUND:Studies have shown that there is a certain correlation between blood lipid levels and bone mineral density in postmenopausal women, but their correlation in men is an open question, which has been less reported. OBJECTIVE:To investigate the relationship between blood lipid levels and bone mineral density in Han and Uygur men with hypertension in Urumqi of Xinjiang Uygur Autonomous Region, as wel as correlation of blood lipid levels with osteoporosis and osteopenia and difference between ethnics. METHODS: A total of 193 male patients with hypertension were categorized into Uygur (n=73) and Han (n=120) groups. Each group was subdivided into osteoporosis or osteopenia group and non-osteoporosis group. Bone mineral density and blood lipid level were analyzed and compared between groups. The correlation between osteoporosis and risk factors was analyzed using logistic regression method. RESULTS AND CONCLUSION:In Uygur hypertension men with osteoporosis or osteopenia, total cholesterol level was positively correlated with the bone mineral density of the femoral neck (r=0.43,P=0.01) and Ward's area (r=0.42, P=0.01); while there were no relationships between blood lipid levels and bone mineral density in Han hypertension men. When a Logistic regression analysis was performed, only total cholesterol level was found to be associated with the presence of osteoporosis or osteopenia after adjustment for body mass index, age and ethnics (OR=1.48,P=0.03). The blood lipid level is associated with bone mineral density in Han and Uygur men with hypertension from Urumqi of Xinjiang Uygur Autonomous Region, which can affect the presence of osteoporosis.

OBJECTIVETo compare clinical outcomes of minimally invasive percutaneous plate osteosynthesis (MIPPO) in treating distal tibial comminuted fractures at early and delayed stage.
METHODSFrom January 2006 to January 2012,66 patients with distal tibial comminuted fractures were treated by MIPPO. All patients were divided into primary group and delayed group according to operation time. There were 31 patients in primary group, including 18 males and 13 females aged 21 to 57 years old with an average of (39.0 +/- 17.8), treated by MIPPO at primary stage,according to Tscherne soft tissue injury, 18 cases were grade I ,12 cases were grade II and 1 case were grade III. Thirty-five patients were treated by MIPPO at delayed stage, including 16 males and 19 females aged 24 to 55 years old with an average of (39.5 +/- 15.2), according to Tscherne soft tissue injury, 6 cases were grade I, 26 cases were grade II and 3 cases were grade III. Operation time, blood loss, hospital stay, fracture healing time and complications of two groups were recorded and observed, Lowa scoring of ankle joint were used to evaluated therapeutic effects at final following and AP and lateral X-rays were used to evaluated fracture reduction and alignment.
RESULTSAll patients were followed up, the time of following-up of primary group was (13.5 +/- 3.5) months, (15.2 +/- 3.8) months in delayed group, there was no significant meaning between two groups (t = 1.882, P = 0.064). There was no significant differences between two groups in operation time and blood loss (P > 0.05), but hospital stay in primary group was shorter than that of delayed group(P<0.05). There was no significant meaning between primary group (5.5 +/- 2.8) and delayed group (6.2 +/- 3.1) in fracture healing time (t = 0.958, P = 0.342); there was no significant meaning between primary group (87.6 +/- 6.8) and delayed group (89.6 +/- 5.2) in Lowa scores at final following-up (t = 1.351, P = 0.182). Two cases occurred postoperative superficial inflammatory reaction around fibular incision in primary group, 1 case occurred postoperative superficial inflammatory reaction around fibular incision and 1 case occurred delayed deep incision infection in delayed group at four months after operation. There was no significant differences in incidence of postoperative soft tissue complications between primary group (6.5%) and delayed group (5.7%) (t = 0.016, P = 0.900).
CONCLUSIONFor distal tibial comminuted fractures with grade I and II of Tscherne soft tissue injury, MIPPO at primary stage can not increase incidence of soft tissue complications, also can obtain the same clinical outcomes just like delayed MIPPO.

Objective To explore the influence of stoves and mode of coal-burning on the prevalence of endemic fluorosis in Guizhou Province.Methods Three previous severe endemic villages and two mild villages(as control)were investigated by ways of random sampling in the present and retrospect epidemiological study on stove usage,coal burning mode and the severity of disease.Results Before the 1990's Of 20th century all the households in the previous severe endemic villages used the open stove without ventilated pipe(chimney)and dehydrated the corn over the coal-fire of the open stoves in house,which resulted in severe pollution of the corn and indoor air by fluoride.After the 1990's,each household,although still dried the corn with the coal fire,used the table stoves and iron stoves increasingly year by year,which resulted in the decrease of the emitted fluoride from the coal fire significantly,reduced the fluoride pollution of the indoor air and the main food,thus the incidence of endemic fluorosis consequently decreased. On the other hand, most of the households in the previous severe endemic villages such as Lianhe and Yuanzi still used the open, unventilated stove without chimney, very few installed chimney leading to outside of the room,the rates being 51.3%(41/80)and 41.7%(35/84),respectively.It was concordant to the high incidence of endemic fluorosis.Compared with 1979,the detective rates of dental fluorosis in the crowd aged above 8 years old were increased significantly in Hehua Village in 2006,90.51%(248/274)and 96.08%(392/408),respectively(χ2=7.85,P<0.01).Conclusions The usage of stoves and mode of coal-burning significantly influence the incidence of the endemic fluorosis caused by domestic coal-burningin Guizhou Province,and inappropriated use of stove and the mode of coal burning are the key factors in cause the prevalence of the severe fluorosis in endemic regions in Guizhou.

Objective To investigate the usage of fluorine-proof iron stove in regions with coal-burning borne endemic fluorosis of Guizhou province and to provide scientific basis for the project management. Methods According to "the local prevention programs against coal-burning borne endemic fluorosis-Guizhou iron stove usage survey scheme", in the 18 counties implemented the project of improving the iron stove from 2005 to 2008, 2 townships were selected randomly in each county of each project annually, 2 villages were selected in each township randomly, and 10 households were checked in each village. The project households were investigated using questionnaire of the related health knowledge and awareness as well as the satisfaction of the households.Results ①The improvement rate of iron stove was 100.00%(1286/1286). ②The overall utilization rate of the improved stove was 94.09% (1210/1286), in which winter was 62.21% (800/1286) and annual was 31.88%(410/1286). ③Among the households that did not use the project stove, 46.05%(35/76) households was due to switch to other clean energy, in addition, 19.74%(15/76) was due to sell or send to other households, and 14.47%(11/76) was still used to use the open kitchen without the ventilating pipe, and still 13.16%(10/76) was due to high coal prices, and 6.58%(5/76) was due to that the improved stove can not meet the needs of life and no longer used. ④Amoag 1261 households investigated, households with damaged furnace was 24.58%(310/1261 ), and the parts damaged were mainly chimney (ventilating pipe) and the furnace core, accounting for 51.94%(161/310) and 29.03%(90/310), respectively. Repair rate of the damaged parts was 32.58%(101/310). ⑤The health knowledge rate was about 82.74% (1064/1286), and the satisfaction of the iron furnace was 88.65% (1140/1286).Conclusions The improved stoves for the prevention of endemic fluorosis in the diseased area meet the people's living habits, and meet their basic livelihood needs. Most project households are still using the improved furnace.But we still need to further strengthen the project management and the health education intervention, establish and improve stove maintenance network, and reach the goal of sustainable control of coal-burning borne endemic fluorosis.
