OBJECTIVETo study the effect of osteogenic inducer (dexamethasone, beta-sodium glycerophosphate and Vitamin C) carried by gelatin sponge on healing and remodeling of tooth extraction sockets.
METHODSFifty rabbits were selected. After extracting the first premolars of bilateral maxillary, the right side tooth extraction sockets were filled with gelatin sponge containing osteogenic inducer as experimental side, tooth extraction sockets on left side were filled with gelatin sponge as control. Every ten rabbits were executed at the end of 1, 2, 4, 8, 12 weeks after tooth extraction. Bone density was measured through digital X-ray images. The specimens were examined by histology. The absorption height of alveolar bone at 12 weeks was measured.
RESULTSX-ray measurement showed that the bone density of experimental side was higher than that of control side at 2, 4, 8, 12 weeks, the difference had statistical significance (P<0.01). The histology examination showed that new bone formation in tooth extraction sockets of experimental side was earlier than that in control side. The absorptional height of alveolar bone had significant difference between experimental side and control side (P<0.01), of which experimental side was less.
CONCLUSIONFilling the osteogenic inducer in tooth extraction sockets can promote the healing and new bone formation and prevent from alveolar bone absorption.

Objective To analyze the lumbar/hip imaging and surface electromyography data of professional equestrian riders,to understand the incidence of chronic diseases in the hip and lower back of the rider,and to explore the causes of chronic pain in riders.Methods Twenty-five equestrian riders from the Shanghai Equestrian Sports Management Center were divided into chronic lower-back pain and chronic hip pain groups.Twelve healthy subjects without hip or lower-back pain were included in the control group.Medical history,X-ray,and magnetic resonance imaging of the hip and lower back,and surface electromyography data of the core muscle were collected.Results The JOA score of the lumbar spine in patients with chronic lower-back pain was significantly lower than that in the control group(P<0.05).The riders had relatively mild chronic hip pain,but the Harris score was significantly lower than that of the control group(P<0.05).The JOA score of the equestrian rider's waist significantly correlated with the Pfirrmann grading.However,the visual analog scale and Harris hip pain scores were not significantly correlated with imaging parameters.The root mean square amplitudes of the rectus abdominis,erector spinalis,rectus femoris,gluteus medius,and multifidus were greater in the riding position than in the normal sitting position(P<0.05).Conclusions The cause of chronic lower-back pain in riders may be related to soft tissue overwork and lumbar degeneration.Changes in the lumbar-hip sagittal sequence pelvic and sacral inclination angles can reflect the degree of lumbar stiffness of the riders.

Radical prostatectomy(RP)was commonly used in localized prostate cancer. For patients with adverse pathological features (APF) after RP, it was controversial about choosing adjuvant radiotherapy or salvage radiotherapy (SRT). Recent studies have found that early salvage radiotherapy(ESRT) had both the same cancer control and reduced overtreatment compared to adjuvant radiotherapy. Nomogram and Gene Classifier(GC) could predict the risk of recurrence after RP and contribute to choose adjuvant radiotherapy or ESRT. PSMA PET/CT was more sensitive to detect distant metastasis after biochemical recurrence, which was helpful to decide whether to implement SRT.

Objective :
To investigate the effects of different root canal filling stop on quality of root canal filling and apical sealing in root canals obturated with GuttaFlow.
Methods:
60 teeth were randomly divided into three groups, using different root canal filling stops to shape the root canals with MTwo (25/06) file. All root canals were obturated with Gutta Flow, and the overfilling of the root canals were recorded and evaluated by X-ray. And the apical microleakage of teeth was evaluated by transparent teeth technique.
Results:
The roots were prepared with MTwo (25/06) as master apical file, the overfilling rate of the root canals in root canal filling stop was higher as the distance from the apex was shorter, but there was no significant difference. The under-filling rate of the root canals in root canal filling stop was higher as the distance from the apex was longer. And the under-filled root canals in root canal filling stop 0.5 mm from the apex showed a statistically significant difference with 2 mm. The mean dyeing penetration length in 0.5 mm and 1 mm group was significantly shorter than 2 mm group.
Conclusion
A suitable root canal filling stop could improve the quality of root canal filling in root canals obturated with GuttaFlow.

OBJECTIVETo observe the impacts of eye acupuncture on neurological deficit and Barthel index in the patients of infarction hemiplegia and explore its function mechanism.
METHODSNinety-six patients of infarction hemiplegia were randomized into an observation group and a control group, 48 cases in each one. In the control group, the routine western medicines such as thrombolysis and antiplatelet aggregation were used. In the observation group, on the basis of the treatment as the control group, eye acupuncture was added atandareas bilaterally, once a day, 5 times a week. Separately, before treatment and after 2 weeks' treatment the score changes of the modified Edinburgh Scandinavia stroke scale (MESSS) and the activity of daily life scale (ADL, Barthel index, BI) were observed and the efficacy was compared between the two groups. The plasma endothelin was determined and compared before and after treatment in the two groups.
RESULTSAfter treatment, the effective rate was 93.8% (45/48) in the observation group and was 79.2% (38/48) in the control group. The effective rate in the observation group was higher apparently than that in the control group (<0.05). The scores of neurological deficit were (13.29±1.45) and (18.24±1.33) in the observation group and control group respectively after treatment, which all lower apparently than (28.44±1.45) and (28.14±1.89) before treatment (both<0.05). Additionally, the difference was significant between the two groups after treatment (<0.05). The scores of Barthel index were (82.33±1.56) and (63.34±2.14) in the observation group and control group respectively, which all higher apparently than (38.53±1.54) and (38.14±2.56) before treatment (both<0.05), and the difference was significant between the two groups after treatment (<0.05). The levels of plasma endothelin were (54.55±11.48)ng/L and (62.44±9.88)ng/L in the observation group and the control group after treatment respectively, which were all lower apparently than (78.24±9.25)ng/L and (78.14±10.78)ng/L before treatment (both<0.05). Additionally, the difference was significant between the two groups after treatment (<0.05).
CONCLUSIONSEye acupuncture effectively improves the neurological deficit and Brathel index in the patients of infarction hemiplegia and comprehensively improves the efficacy. The effect mechanism is possibly relevant with reducing plasma endothelin.

Objective:To analyze the site of vestibular nerve damaged in patients with acute vestibular neuritis. Methods:Fifty-seven patients with acute vestibular neuritis were recruited, and each patient underwent caloric irrigation test, video head impulse test(vHIT) and vestibular evoked myogenic potentials(VEMPs). The results were further analyzed. Results:Analysis of abnormal rates of different vestibular function tests: the abnormal rate of caloric irrigation test, horizontal semicircular canal vHIT, anterior semicircular canal vHIT, and posterior semicircular canal vHIT were 92.98%, 92.98%, 92.98%, and 52.63%, respectively. The abnormal rate of cervical vestibular evoked myogenic potentials(cVEMP) and ocular vestibular evoked myogenic potentials(oVEMP) were 52.63% and 89.47%. The abnormal rate of caloric irrigation test, horizontal semicircular canal vHIT, anterior semicircular canal vHIT, and oVEMP were significantly higher than posterior semicircular canal vHIT and cVEMP(P<0.01). Combination analysis of different vestibular function tests: there are twenty-six patients(45.61%, superior and inferior vestibular nerve) with abnormal caloric irrigation test, video head impulse test, and VEMPs. There are twenty-five patients(43.86%, superior vestibular nerve) with abnormal caloric irrigation test, horizontal semicircular canal vHIT, anterior semicircular canal vHIT, and oVEMP. There are 4 patients(7.02%, inferior vestibular nerve) with abnormal posterior semicircular canal vHIT and cVEMP. There are two patients(3.51%, ampullary vestibular nerve) with abnormal caloric irrigation test, horizontal semicircular canal vHIT, and anterior semicircular canal vHIT. The rate of superior and inferior vestibular neuritis and superior vestibular neuritis were significantly higher than inferior vestibular neuritis and ampullary vestibular neuritis(P<0.01). Conclusion:Acute vestibular neuritis subtypes can be divided into four categories: superior and inferior vestibular neuritis, superior vestibular neuritis, inferior vestibular neuritis, and ampullary vestibular neuritis. Video head impulse test can accurately assess the site of vestibular nerve damage in patients with acute vestibular neuritis. In addition, vHIT combined with VEMPs can provide objective evidence for the diagnosis of ampullary vestibular neuritis.
