BACKGROUND:Bioglass has good biocompatibility and biological activity, which can be combined with calcium phosphate bone cement to form an absorbable bioglass that has the advantages of both materials and is expected to have a better use of space. OBJECTIVE:To explore the mechamism of the new type of absorbable bioglass injection for vertebral body supporting and osteogenic induction in osteoporosis rats. METHODS:Twenty-seven female Sprague-Dawley rats were selected to make osteoporosis models by bilateral ovariectomy, and after 1 month, the rats were randomized into three groups. Bone defect models were established in the lumbar L4 segment of al the rats. Rats in the experimental group were subjected to absorbable bioglass injection; rats in the control group 1 underwent polymethylmethacrylate bone cement injection; and rats in the control group 2 were given injectable calcium phosphate. Twelve weeks after implantation, the compressive strength, degradation and osteogenesis of the implant materials were detected, and levels of serum bone morphogenetic protein-2 and transforming growth factor-β were measured. RESULTSAND CONCLUSION: The compressive strength, hydroxyapatite deposition amount, and weight loss ratio in the experimental group were significantly higher than those in the two control groups (P < 0.05); the relative volume, thickness and number of bone trabeculae in the experimental group were significantly higher than those in the control groups (P < 0.05); the bone morphogenetic protein-2 and transforming growth factor-β protein levels in the experimental group were significantly higher than those in the two control groups (P < 0.05). These findings indicate that the new-type absorbable bioglass can greatly strengthen the vertebral body supporting and promote osteogenic effect in osteoporosis by enhancing the bone morphogenetic protein-2 and transforming growth factor-β protein levels.

BACKGROUND:With the extensive application of cone-beam CT in oral and craniofacial surgery, a clear hyoid bone position indicator for normal population has important implications for the change of hyoid bone position before and after orthodontics. OBJECTIVE:To determine the cone-beam CT measurement range of hyoid bone position in populations aged 6-19 years from Shandong, so as to provide a reference marker for the change of hyoid bone position before and after orthodontics in local children and adolescents. METHODS:Totaly 254 healthy children (120 males and 134 females) aged 6-19 years from Shandong Province were subjected to cone-beam CT scan of the hyoid bone. Mimics10.01 was used to evaluate the linear and angular measurements of hyoid bone position, and then the normal value range was confirmed. Independent-samplet-test was used for analysis of gender difference and 95% confidence interval was calculated. RESULTS AND CONCLUSION: There were gender differences in a part of indicators of hyoid bone position among 14-15 years, 16-17 years, 18-19 years groups (P < 0.05). For children aged 12-13 years, the hyoid bone position vertical to the base of skul and upper jaw bone is lower in males than in females. For children aged 14-15 years and 18-19 years, the hyoid bone horizontal to the cervical spine is more forward in males than in females.

Objective To observe the effect of moxibustion on the proliferation of neural stem cells after cerebral ischemia- reperfusion in rat models.Method The middle cerebral artery occlusion (MCAO) model was developed by using modified Zea-Longa method. Seventy-two Wistar rats were randomized into group A (sham-operation group), group B (model group) and group C (moxibustion group). Each group was then further divided into 4 sub-groups according to different time points: 3 d, 7 d, 14 d, and 21 d, 6 rats in each sub-group. For each group, Baihui (GV 20) and bilateral Taiyang (EX-HN 5) were selected to study. The proliferated cells were marked by intraperitoneal injection of BrdU, and TTC staining and HE staining were adopted to detect the pathological changes of brain tissues after cerebral ischemia-reperfusion. Immunohistochemical method was used to dynamically detect the positive expressions of BrdU and Nestin cells in DG and SVZ zones at different time points, and microscope image analysis was taken to study the positive expressions.Result The neurological deficit score in group C was significantly lower than that in group B at each time point (P<0.05). The neurological deficit score in group C was significantly different from that in group B at the same time point (P<0.05). Moxibustion can up-regulate the expression of BrdU in SVZ and DG, and the increase started from the 3rd day and reached the peak on the 7th day. The increase of BrdU expression in group C was more significant than that in group B (P<0.05). Moxibustion can up-regulate the expression of Nestin in SVZ and DG, and the increase started from the 3rd day and reached the peak on the 7th day. The increase of Nestin expression in group C was more significant than that in group B (P<0.05).Conclusion Moxibustion can remarkably promote the recovery of nerve function and the proliferation of BrdU and Nestin after cerebral ischemia-reperfusion in rats.

Objective To identify the risk factors associated with incontinence-associated dermatitis (IAD) in ICU patients with enteral nutrition associated diarrhea (ENAD), and to provide information for taking evidence-based preventive measures. Methods We used a case-control study to collect data. Information of the patients (n=55) and controls (n=55) were retrieved from the medical records of 2 intensive care units (ICUs). The patients with IAD and the controls without IAD were matched with age, gender and ward. Information on disease-related information, perineal environment, drug use and nutritional status were collected. Results The simple factor analysis showed that the risks of IAD were related to coronary heart disease (CHD )(χ2=3.96), composite variable for perfusion (χ2=7.33), APACHE II score (χ2=9.87), FiO2 (Z=-2.96), artificial airway (χ2=93.91), ENAD days (Z=-5.45), stool property (χ2=8.46), antibacterial drug use (χ2=5.55), steroid medicine (χ2=11.34) and enteral nutrition days(Z=-3.33), P<0.05. Logistic regression analysis showed that FiO2(P<0.05,OR=1.03, OR95%CI=1.01-1.06), APACHE Ⅱscore(P<0.05,OR=3.12, OR95%CI=1.01-9.64)and ENAD days(P<0.01,OR=1.64, OR95%CI=1.29-2.10)was independent risk factors for IAD. Conclusions The higher of FiO2, APACHE II score over 15 points and the longer of ENAD days, patients are more likely to occur IAD. Early monitoring and prevention of IAD are recommended to promote skin health.
