BACKGROUND: Several studies have demonstrated that many American women who are at high risk of developing osteoporosis have higher levels of serum phosphorus. This indicates that some substances which can lower the serum level of phosphorus will supply a new and effective method to prevent and treat osteoporosis.OBJECTIVE: To observe the influences of porcine bone protein on bone mineral density (BMD) and serum levels of calcium and phosphorus in a rat model of osteoporosis.METHODS: Wistar rat models of osteoporosis were established by intramuscular injection of dexamethasone. Rat models were randomly divided into physiological saline, Jiegu Qili tablet, 50, 100, 200 mg/kg porcine bone protein groups. Rats that did not receive any treatments served as normal controls. After 12 weeks of treatment, serum was collected and serum levels of phosphorus and calcium were determined by biochemistry method. At the same time, tibia sections were made to determine tibial DMD by QDR-400 dual energy X-ray absorptiometry and to observe tibia marrow cavity by hematoxylin-eosin staining.RESULTS AND CONCLUSION: There was no significant difference in serum level of calcium among groups (P>0.05).Compared with the physiological saline group, serum level of phosphorus in the 50, 100, 200 mg/kg porcine bone protein groups was significantly decreased (P < 0.05). BMD was significantly higher in the 50, 100, 200 mg/kg porcine bone protein, Jiegu Qili tablet groups than in the physiological saline group (P < 0.05). The tibia marrow cavity was smallest in the normal control group and largest in the physiological saline group. The tibia marrow cavity was larger in the 50, 100, 200 mg/kg porcine bone protein,Jiegu Qili tablet groups than in the physiological saline group. These results indicate that porcine bone protein cannot change the serum level of calcium, but it lowers serum level of phosphorus, and increases BMD, in a rat model of osteoporosis. However, the dose-dependent effect of porcine bone protein was not observed within the present experimental dosage. In addition, porcine bone protein can also reduce the marrow cavity of the tibia of rats with osteoporosis.

Objective:To explore the visual fixation patterns during facial emotion recognition and the association between fixation duration percentage (FDP) of eye region with social impairment among high-functioning autism spectrum disorders (HFASD).Methods:Children were recruited from the Child and Adolescent Behavior Research Center of Sun Yat-sen University, Guangzhou, between July and December 2019 for case control study. A total of 42 children with HFASD and 23 age-and gender-matched typical development (TD) children were enrolled. Based on their performance during the facial emotion recognition task, HFASD children were further divided into ASD-1 group (correctly recognized both happy and fear emotions) and ASD-2 group (recognized happy emotions only). During the free viewing task, an infrared eye tracker was used to record the gazing data of children in the three groups. The social responsiveness scales (SRS) was utilized to evaluate HFASD children′s social impairment, with the cutoff score of 75 to differentiate those from mild and severe social impairment. The differences of FDP among the three groups were analyzed by the Analysis of Variance (ANOVA) model. Mixed linear regression model was conducted to evaluate the associations between social impairment and FDP of eye region among HFASD children.Results:The final sample consists of 25 ASD-1 (20 males, aged (7.9±1.0) years), 17 ASD-2(14 males, aged (7.2±1.2) years), and 23 TD (12 males, aged (7.7±1.3) years) children. There were no significant differences in age and gender among three groups ( F=2.05, χ2 =10.08, P=0.14 and 0.07, respectively). For the happy emotion, there are significant differences in eye FDP among the three groups (TD: 0.37±0.20, ASD-1: 0.35±0.20, ASD-2: 0.47±0.24, F=3.97, P=0.02). Mixed linear regression model revealed that, adjusting for emotion, gender, age and intelligence quotient, ASD children′s eye FDP negatively associates with social impairment ( OR=0.15, 95% CI: 0.06-0.35, P<0.01). Conclusions:Longer FDP is associated with milder social impairment among HFASD children. HFASD children with facial emotion recognition difficulties require longer fixation to recognize happy emotions.

Background::The clinical characteristics of patients with the comorbidities of hypertension and coronary artery disease (HT-CAD) and atrial fibrillation (AF) are largely unknown. This study aimed to investigate the prevalence of AF in patients with HT-CAD and clinical characteristics of patients with both HT-CAD and AF.Methods::This cross-sectional study was conducted in Chinese People’s Liberation Army General Hospital in Beijing, China, and included 20,747 inpatients with HT-CAD with or without AF from August 2008 to July 2018. We examined the overall prevalence, clinical characteristics, comorbidity profiles, treatment patterns, and blood pressure (BP) control of patients with both HT-CAD and AF. Multivariate logistic regression was used to investigate the associations of cardiovascular risk factors with AF in patients with HT-CAD.Results::The overall prevalence of AF in patients with HT-CAD was 4.87% (1011/20,747), and this increased with age; to be specific, the prevalence in women and men increased from 0.78% (2/255) and 1.02% (26/2561) at the age of <50 years to 8.73% (193/2210) and 10.28 % (298/2900) at the age of ≥70 years, respectively. HT-CAD patients who had AF had a higher prevalence of cardiovascular-related comorbidities than those without AF. Multivariate logistic regression showed that age, gender (male), body mass index, heart failure, and chronic kidney disease were independently associated with the risk of AF in patients with HT-CAD. For those with both HT-CAD and AF, 73.49% (743/1011) had a CHA 2DS 2-VASc score of ≥4, and only about half of them had the BP controlled at <140/90 mmHg, which indicated a high risk of thromboembolism and stroke. The use of oral anticoagulation increased during the study period (10.00% [20/200] in 2008 to 2011 vs. 30.06% [159/529] in 2015 to 2018, P < 0.01), but remained at a relatively low level. Conclusions::AF is highly prevalent among patients with HT-CAD. Patients with both HT-CAD and AF have a higher prevalence of cardiovascular-related comorbidities, lower BP control rate, and lower use of oral anticoagulation.

Objective:To explore the risk factors associated with tibia fractures in children with congenital anterolateral bowing of the tibia (ALBT).Methods:A retrospective analysis was conducted on data from 87 children diagnosed with ALBT at the Children's Hospital of Hunan Province from January 2012 to January 2020. The collected data included age at initial diagnosis, affected limb side, whether there was a concomitant type I neurofibromatosis, whether there was a concomitant fibular pseudoarthrosis, whether there was concomitant ankle joint deformity, whether there was bone cystic change in the region of tibial bowing deformity, location of the apex of the bowing deformity, diameter of the tibial bowing deformity on the affected side, diameter on the healthy side in the same plane as the tibial bowing deformity, angle of lateral bending deformity of the tibia, angle of anterior bending deformity of the tibia, occurrence of tibia fracture, history of trauma before fracture, location of fracture, and age at the time of fracture. The follow-up endpoint was January 2023. Receiver operating characteristic (ROC) curves were used to determine the optimal cutoff values for the angles of lateral and anterior bending deformity of the tibia and the ratio of cross-sectional areas. The correlation between the above factors and tibial fractures in children was analyzed by single factor survival analysis, and the indicators with statistical significance were included in multivariate Cox proportional risk regression analysis to determine the risk factors for tibial fractures in children with ALBT.Results:Of the 87 children diagnosed with ALBT, the median age at initial diagnosis was 14.0 months (range, 1-93 months), with 42 males and 45 females, 44 left-sided and 43 right-sided cases. The median follow-up time for non-fracture cases was 42.0 months (range, 1-124 months). At the last follow-up, 43 children had experienced fractures, while 44 had not. The average time to fracture-free survival was 70.3 months, the median fracture-free survival time was 55.0 months, and the median survival time without fractures was 42.0 months. The ROC curve results indicated a cutoff value of 25.55° for the lateral bending angle of the tibia and 32.63° for the anterior bending angle of the tibia, with no statistically significant significance for the cross-sectional area ratio [AUC=0.54, 95% CI (0.42, 0.66), P=0.530]. Single-factor analysis of fracture-free survival suggested that there were statistically significant differences in the intergroup fracture-free survival rates of four factors: lateral bending angle of the tibia (χ 2=7.06, P=0.008), anterior bending angle of the tibia (χ 2=8.96, P=0.003), history of trauma (χ 2=18.26, P<0.001), and tibial bone cystic change (χ 2=4.30, P=0.038). The results of the multivariate Cox proportional hazards regression analysis showed that a lateral bending angle of the tibia≥25.55° ( HR=2.73, P=0.007), tibial bone cystic change ( HR=2.35, P=0.018), and history of trauma ( HR=2.65, P=0.004) were all positively correlated with fractures. Conclusion:The main risk factors for tibia fractures in children with ALBT include trauma, tibial bowing deformity with concomitant bone cystic change, and lateral bending angle of the tibia≥25.55°.
