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.

Objective To observe the effect of health education and installation of improved stove in control of coal-burning-borne endemic fluorosis in Pingba County of Guizhou Province.Methods Two towns(Shizi and Qibo) of Pingba County that had implemented the health education and installed the improved stoves for control of coal-burning-borne endemic fluorosis were selected as the investigation sites.Two villages in each selected town and 30 householders as well as all students of grade 4-6 were investigated.Questionnaires were made by survey of the fluorosis control knowledge,household investigations were used to know the use of household stoves,corn and peppers drying method,and the dental fluorosis of children aged 8-12 were examined by Dean methods before the intervention(2006) and after implementation(2009) of health education and improvement of stoves.Results The awareness of fluorosis control among students and households after the intervention was 97.36％ (405/416) and 86.46％(415/480),respectively,and the difference was statistically significant(x2 =658.86,163.10,all P ＜ 0.01) compared with that before the intervention [32.19％(1083/3364),43.33％(130/300)].Correct using rate of the household stoves was 95.42％ (229/240) after the intervention and 45.85％ (3976/8672) before the intervention,the difference was statistically significant(x2 =230.25,P ＜ 0.01).The correct rates of drying corn and chili were 91.67％ (110/120) and 97.50％ (117/120) before the intervention,and 20.00％ (12/60),26.67％ (16/60) after the intervention,the difference was statistically significant(x2 =94.07,104.02,all P ＜ 0.01).The incidences of dental fluorosis of children aged 8-12 were 31.21％(1305/4182) after the intervention and 87.71％(2856/3256) before the intervention,the difference was statistically significant(x2 =2371.91,P ＜ 0.01).Conclusions The measures of health education and intervention of stove improvement in Pingba County of Guizhou Province for prevention and control of coal-burning-borne endemic fluorosis is effective.

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.

OBJECTIVETo understand preliminary relation between patient's confident degree in acupuncture and moxibustion with the therapeutic effect on pain.

METHODSFifteen cases with pain were investigated. The confident degree for acupuncture and moxibustion and pain degree were evaluated by the patient with visual analogue scale (VAS), and the pain VAS scores before and after acupuncture were recorded as the indexes for assessment of the therapeutic effect.

RESULTSAfter acupuncture treatment, the average pain VAS score was decreased by 3.3 +/- 2.8 (P< 0 . 5). There was no significant correlativity between the patient's confident degree VAS and the pain VAS change rate before and after the treatment (R = 0.62, P = 0.83).

CONCLUSIONThere is no significant correlativity between the confident degree of the patient of pain in acupuncture and moxibustion and clinical therapeutic effect.
