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.

According to Chinese medicine, the atlantoaxial joint is a composite joint composed of tendons and bones, and the stability of the joint depends on the 'tendon-bone balance' involving tendons, ligaments, atlas and axis. Multiple causes of 'tendon off-position, joint subluxation' will lead to joint 'tendon-bone imbalance', which will evolve into atlantoaxial subluxation (AAS), endangering human health. Chinese therapeutic massage (tuina) is a very effective treatment for AAS in adults, but conventional manipulations are prone to ineffectiveness or accidents due to neglect of the causal relationship of the 'tendon-bone imbalance' and inappropriate manipulations. Compared with conventional manipulations, the rational choice of modified manipulations under the guidance of 'tendon-bone balance' theory is more effective and less risky, and more worthy of clinical promotion. From the 'tendon-bone balance' theory, we considered the shortcomings of conventional manipulations, and introduced several modified manipulations that have their own strengths in 'tendon smoothing' and 'bone setting', in order to provide new ideas for treatment of AAS in adults.

Objective:To establish a comprehensive and effective scoring model based on ultrasonic characteristics for predicting the restenosis risk after superficial femoral artery stenting, in order to assess the possibility of in-stent restenosis and to provide guidance for the selection of therapeutic strategies.Methods:A retrospective review of a database of 328 patients (381 limbs) undergoing superficial femoral artery stents in Xuanwu Hospital, Capital Medical University from January 2016 to January 2018 was made as a modeling group.In the modeling cohort, the multivariate logistic regression analysis was performed to screen independent risk factors for in-stent restenosis. A predictive scoring model of restenosis risk was established with weighted score of independent risk factors according to the odd ratio values. Based on the best cut-off value of the receiver operating characteristic (ROC) curves, the scoring table was divided into low-risk and high-risk groups of restenosis.Results:Multivariate logistic regression analysis showed that 8 factors were included in the score system to establish the scoring model of in-stent restenosis risk prediction including calcified plaque, peak systolic velocity of popliteal artery<40 cm/s, runoff scores≥4, ankle-brachial index<0.5, female (1 point each); complicated stroke, complicated chronic renal disease, total lesion length 15.0-24.9 cm (2 points each); total lesion length≥25.0 cm (3 points), a total of 12 points in the model. The validation indicated that the scoring system had good predictive value(AUC=0.775, 95% CI=0.727-0.824, P<0.001) and goodness of fit (Hosmer-Lemeshow χ 2=4.921, P=0.766). The agreement with digital subtraction angiography(DSA) was good (Kappa value=0.609). The scoring system was further divided into the low-risk restenosis (0-5 points) and high-risk restenosis (6-12 points) according to the best cut-off value of 5.5, with a sensitivity of 68.1%, a specificity of 74.6%, and the accuracy of 72.7%. Conclusions:The superficial femoral artery in-stent restenosis risk predicting score model based on ultrasonic characteristics may accurately predict the restenosis preoperatively. It provides a theoretical basis for the precise surgical plans.
