With the development of medical radiography, cone beam computed tomography (CBCT) has been widely used in stomatology because of its numerous advantages, such as adequate spatial resolution, low radiation, undistorted three- dimensional tissue information, and good applicability for hard tissue imaging. Traditional periapical radiography is based on two-dimensional image which displays the three-dimensional object and its surrounding structures. Periapical radiography can only show the overlapping mesio-distally direction bone destruction, can't show buccolingual direction bone destruction. As a kind of three-dimensional imaging technology, CBCT can show three-dimensional structure of the organization from sagittal, coronal and axial direction, to overcome the defect of two-dimensional image such as overlap and deformation. CBCT has a unique advantage than periapical radiography in the diagnosis and treatment for periapical disease. This review will summarize the difference between CBCT and periapical radiography in the periapical disease.

Objective:To establish a nomogram model for predicting the risk of intracranial hemorrhage in patients with acute cerebral infarction after mechanical thrombectomy.Methods:The clinical data of 251 patients with acute cerebral infarction who underwent mechanical thrombectomy in Shengjing Hospital Affiliated to China Medical University from January 2017 to December 2019 were retrospectively analyzed. Logistic regression model was used to analyze the independent risk factors of intracranial hemorrhage after mechanical thrombectomy. A nomogram prediction model based on independent risk factors was established to verify the prediction and accuracy of the model.Results:The analysis results of logistic regression model were as follows: age ( OR=1.303, 95% CI:1.184-1.433), the time from infarction to re-canalization ( OR=4.306, 95% CI:2.497-7.425), preoperative NISS score ( OR=7.584, 95% CI:2.221-25.900), preoperative computer tomography (CT) low-density lesions ( OR=7.954, 95% CI:1.176-53.792) were independent risk factors for intracranial hemorrhage after mechanical thrombectomy in patients with acute cerebral infarction ( P<0.05). Based on the above 4 independent risk factors, a nomogram predictive model of intracranial hemorrhage risk after mechanical thrombectomy was established. The Bootstrap internal verification method proved that the model had good prediction accuracy, and the receiver operating characteristic (ROC) curve analysis testified that area under curve (AUC) area was 0.966. Conclusions:The risk nomogram prediction model has good accuracy, discrimination and good prediction ability, which can improve the diagnostic efficacy of intracranial hemorrhage after mechanical thrombectomy in patients with acute cerebral infarction.

Objective To observe the clinical efficacy of acupuncture-moxibustion in treating endometriosis (EM). Method Fifty EM patients were randomized into two groups, 25 cases in each group. The treatment group was intervened by acupuncture-moxibustion, while the control group was intervened by oral administration of Mifepristone tablets. Abdominal pain, pelvic lump, and relevant indicators were observed before and after the treatment, and the therapeutic efficacies were compared.Result After 6-month treatment, symptoms including abdominal pain obviously subsided in the treatment group and the total effective rate was 92.0%, versus 52.0% in the control group, and the between-group difference was statistically significant (P<0.01). The pelvic lump size was significantly changed after the treatment in both groups (P<0.05), suggesting that the lump size became smaller in both groups after the treatment;there was a significant difference in comparing the pelvic lump size between the two groups after the treatment (P<0.05), indicating that the lump size was reduced more significantly in the acupuncture-moxibustion group. The level of serum CA125 changed significantly after the treatment in both groups (P<0.05), suggesting that serum CA125 dropped in both groups after the treatment; there was a significant difference in comparing the level of serum CA125 between the two groups after the treatment (P<0.05), indicating that serum CA125 dropped more significantly in the acupuncture-moxibustion group. A year later, there was a significant difference in comparing the relapse rate between the two groups (P<0.05), revealing that the relapse rate was significantly lower in the acupuncture-moxibustion group than in the medication group.Conclusion Acupuncture-moxibustion can produce a marked therapeutic efficacy in treating EM.

Fast-track surgery is a new concept in general surgery nowadays.Fluid therapy,one part of fast-track surgery,is an important part,which go through with the whole perioperative process.Fluid therapy includes short time of fasting,no bowel preparation,appropriate postoperative fluid management,new monitoring technologies of hemodynamics,and so on.This new approach benefits preventing postoperative complications such as postoperative insulin resistance and cardiopulmonary failure.Still,this is a new concept which needs to be examed in clinical practices.In the future,the challenges lie within procedure-specific approaches,goaldirected therapy,the balance between the amount and composition of colloid vs crystalloid and the developments of the optimal techniques to monitor intra-and post-operative hemodynamics.

Objective To investigate the acaroid mite pollution in houses in Huaibei area,Anhui province and to prevent allergic diseases caused by acaroid mites. Methods The samples of acaroid mites were collected from the houses,hotels and undergraduate dormitories,then the acaroid mites were separated,classed and counted. Results Fifteen kinds of acaroid mites were detected from the samples,belonging to 5 families,11 genera. The analysis showed that average density of acaroid mites in the common houses ranked the first,32.5. The values of the species richness index R was 1.36,the species diversity index was 2.16,the species evenness index was 0.9. Conclution The density of acaroid mites in the common houses is higher in Huaibei area and the effective measure should be taken to control the acaroid mites.

Objective To observe the efficacy and prognosis of aconite-cake-partitioned moxibustion plus acupuncture in treating peptic ulcer.Method Thirty-four patients in the treatment group were intervened by aconite-cake-partitioned moxibustion plus acupuncture, while thirty-three patients in the control group were by Omeprazole Enteric-coated Capsules. The clinical efficacy, the effect on ulcer under gastroscope and Hp, and the therapeutic efficacy 12 months after the intervention were evaluated.Result The total effective rate was 91.2% in the treatment group versus 72.7% in the control group, and the difference was statistically significant (P<0.05). For ulcer by gastroscopy, the total effective rate was 85.3% in the treatment group versus 69.7% in the control group, and the difference was statistically significant (P<0.05). After intervention, the Hp level didn’t show significant change (P>0.05). The relapse rate of the control group was higher than that of the treatment group 12 months after the intervention.Conclusion Aconite-cake-partitioned moxibustion plus acupuncture can produce a higher efficacy than Western medication in treating peptic ulcer.
