RESUMO
@#AIM: To explore the correlation between age, OCT characteristics and the efficacy of anti-vascular endothelial growth factor(VEGF)drugs in the treatment of macular edema secondary to central retinal vein occlusion(CRVO).<p>METHODS: Retrospective case-control study. From July 2017 to July 2019,47 eyes of 47 patients with CRVO were included and divided into group A(elderly group, age>50y, <i>n</i>=27)and group B(young and middle-aged group, age≤50y, <i>n</i>=20). All patients were received anti-VEGF therapy(3+PRN)and followed up for at least 12mo. The best corrected visual acuity(BCVA), the number of hyper-reflective dots(HRD), the average retinal thickness(ART)and central retinal thickness(CRT)were observed before and after treatment. The number of injections, the recovery rate of outer membrane(ELM)and ellipsoidal zone(EZ)were compared between the two groups, and the related indexes affecting visual prognosis were analyzed. <p>RESULTS: After anti-VEGF treatment, BCVA was improved, the number of HRD decreased, CRT and ART thinned in both groups. During the follow up of 12mo after treatment, the frequency of injection of anti-VEGF drugs in the elderly group was higher than that in the young and middle-aged group(8.4±2.1 times <i>vs</i> 7.3±1.7 times, <i>P</i>=0.047), but there was no difference in the recovery rates of ELM and EZ between the two groups. BCVA in the elderly group was correlated with the age, HRD, ELM and EZ(all <i>P</i><0.05). BCVA was correlated with age, ART, HRD, ELM and EZ in young and middle-aged patients(all <i>P</i><0.05). <p>CONCLUSION: Intravitreal injection of anti-VEGF drugs can effectively treat macular edema secondary to CRVO and the prognosis of young and middle-aged patients is better than that of elderly patients. Age and OCT indexes such as HRD, ELM and EZ are related to visual prognosis.
RESUMO
In the current study, we sought to investigate whether T-type Ca channels (TCCs) in the brain are involved in generating post-anesthetic hyperexcitatory behaviors (PAHBs). We found that younger rat pups (postnatal days 9-11) had a higher incidence of PAHBs and higher PAHB scores than older pups (postnatal days 16-18) during emergence from sevoflurane anesthesia. The power spectrum of the theta oscillations (4 Hz-8 Hz) in the prefrontal cortex was significantly enhanced in younger pups when PAHBs occurred, while there were no significant changes in older pups. Both the power of theta oscillations and the level of PAHBs were significantly reduced by the administration of TCC inhibitors. Moreover, the sensitivity of TCCs in the medial dorsal thalamic nucleus to sevoflurane was found to increase with age by investigating the kinetic properties of TCCs in vitro. TCCs were activated by potentiated GABAergic depolarization with a sub-anesthetic dose of sevoflurane (1%). These data suggest that (1) TCCs in the brain contribute to the generation of PAHBs and the concomitant electroencephalographic changes; (2) the stronger inhibitory effect of sevoflurane contributes to the lack of PAHBs in older rats; and (3) the contribution of TCCs to PAHBs is not mediated by a direct effect of sevoflurane on TCCs.
RESUMO
Objective To evaluate the accuracy of different anatomic landmark methods in determining the size of nasopharyngeal airway.Methods Fifty-two patients of both sexes,aged 16-60 yr,of American Society of Anesthesiologists physical status Ⅰ to Ⅲ,with body mass index of 18-30 kg/m2,scheduled for elective awake craniotomy for supratentorial tumors under sedation-awake-sedation anesthesia,were included.For each patient,the distance from the apex of nose to the right tragus (NT),distance from apex of nose to the right mandibular angle (NM),and thyro-mental distance (TM) were measured and marked on a transnasal tube correspondingly.The patients were placed in supine position without pillow,topical anesthesia (nasal mucosal surface) was performed with 2% lidocaine,and patients were sedated with midazo1am,propofol and dexmedetomidine.When Observer's Assessment of Alertness/Sedation Scale score was 2 or 3 points,the tube was transnasally inserted to each marked depth.When the three marked depths mentioned above were reached,the positions of the tube's tip were checked using a fiberoptic bronchoscope and recorded as:above epiglottis (the tip of the tube was placed between the epiglottis and the free edge of soft palate) or below epiglottis (the tip of the tube placed at or beyond the epiglottis).Results When the depth reached the NT mark,the tube's tip was above epiglottis in 14 cases (27%),and the tube's tip was below epiglottis in 38 cases (73%).When the depth reached the NM mark,the tube's tip was above epiglottis in 31 cases (60%),and the tube's tip was below epiglottis in 21 cases (40%).When the depth reached the TM mark,the tube's tip was above epiglottis in 52 cases (100%).Compared with the NM and NT methods,the TM method had a higher probability with the tube's tip above epiglottis when used to determine the depth of insertion (P<0.01).Conclusion TM anatomic landmark method provides higher accuracy in determining the size of nasopharyngeal airway.
RESUMO
Objective To explore the effect of mindfulness decompression therapy on the house-bound elders with depression. Methods By the stratified random sampling method,screening 1 371 more than 60 year old people in the community,86 cases housebound elders with depression were randomly divided into intervention group and control group. Intervention group received mindfulness decompression therapy in-tervention,and control group with blank control. The housebound state assessment scale and the Geriatric Depression Scale (GDS) were evaluated before intervention,4 weeks after intervention and 8 weeks after in-tervention. Results During the intervention period,3 cases were dropped out,83 cases were all included (41 cases in the intervention group and 42 cases in the control group). There was no significant difference between the two groups in the general situation before the intervention (P>0. 05),and the balance between the two groups was comparable. After intervention,the total score of housebound (8. 4±2. 0) and the total score of depression (12. 2±4. 3) in the intervention group were lower than those in the control group,and the differences were statistically significant(P<0. 05). Conclusion Mindfulness-based stress reduction can ef-fectively improve the depression and housebound condition of the elderly.

RESUMO
<p><b>OBJECTIVE</b>To evaluate remineralization efficacy of an arginine containing dentifrice on initial enamel carious lesions in vitro.</p><p><b>METHODS</b>Human enamel blocks with early lesions were prepared and randomly divided into three treatment groups: negative control group (distilled and deionized water), positive control group (fluoride containing dentifrice and 0.14% sodium monofluorophosphate), and test dentifrice group (8.0% arginine and 0.14% sodium monofluorophosphate). The lesions were subjected to a pH-cycling regime for 10 days. Surface enamel microhardness of the enamel blocks from each group was measured before and after pH cycling, and the surface microhardness recovery was calculated. Then, specimens were analyzed for enamel fluoride uptake (EFU) through acid etching method, after which they were treated in demineralization solution for a 2 h period of acid challenge. The other specimens were sectioned and examined through polarized light microscopy.</p><p><b>RESULTS</b>In the test dentifrice group, microhardness recovery and EFU were significantly higher than those in the negative control and positive groups. The test dentifrice group was significantly resistant to the acid challenge compared with the other groups. Conspicuous remineralization of enamel subsurface lesions was observed under polarized light microscopy among samples treated with test dentifrice, whereas the control groups showed no significant changes on enamel subsurface lesions.</p><p><b>CONCLUSION</b>This study presents the potential superiority of Pro-Argin dentifrice over conventional fluoride dentifrice in promoting the remineralization of initial enamel lesions.</p>

Tooth bleaching agents may weaken the tooth structure. Therefore, it is important to minimize any risks of tooth hard tissue damage caused by bleaching agents. The aim of this study was to evaluate the effects of applying 45S5 bioglass (BG) before, after, and during 35% hydrogen peroxide (HP) bleaching on whitening efficacy, physicochemical properties and microstructures of bovine enamel. Seventy-two bovine enamel blocks were prepared and randomly divided into six groups: distilled deionized water (DDW), BG, HP, BG before HP, BG after HP and BG during HP. Colorimetric and microhardness tests were performed before and after the treatment procedure. Representative specimens from each group were selected for morphology investigation after the final tests. A significant color change was observed in group HP, BG before HP, BG after HP and BG during HP. The microhardness loss was in the following order: group HP>BG before HP, BG after HP>BG during HP>DDW, BG. The most obvious morphological alteration of was observed on enamel surfaces in group HP, and a slight morphological alteration was also detected in group BG before HP and BG after HP. Our findings suggest that the combination use of BG and HP could not impede the tooth whitening efficacy. Using BG during HP brought better protective effect than pre/post-bleaching use of BG, as it could more effectively reduce the mineral loss as well as retain the surface integrity of enamel. BG may serve as a promising biomimetic adjunct for bleaching therapy to prevent/restore the enamel damage induced by bleaching agents.

OBJECTIVE@#To determine the rules that apparent diffusion coefficient (ADC) changes with time and space in cerebral infarction, and to provide the evidence in defining the stage, guiding treatment or judging the prognosis in infarction.@*METHODS@#Eighty-eight work-ups in 69 patients with cerebral infarction (8 hyperacute, 35 acute, 20 subacute, and 25 chronic infarctions) were imaged with both conventional MRI and diffusion weighted imaging. The average ADC, the average relative ADC (rADC), and the ADC or rADC from the center to the periphery of the lesion were calculated.@*RESULTS@#The average ADC and the average rADC of hyperacute and acute infarction lesion depressed obviously. The average ADC and the average rADC of subacute infarction lesion were significantly higher than those of hyperacute and acute infarction lesion (P < 0.05), and some approached the values of uninjured side which appeared "pseudonormal values" at 10 to 14 days. The average ADC and the average rADC in chronic infarction lesion were the highest (P < 0.05). The longer the prognosis, the higher the average ADC and the average rADC of infarction lesion. The ADC and the rADC in 7 hyperacute and 26 acute lesions had gradient signs that these lesions increased from the center to the periphery. The ADC and the rADC in 15 subacute lesions had adverse gradient signs that these lesions decreased from the center to the periphery.@*CONCLUSION@#The ADC and the rADC of infarction lesions have evolution rules with time and space corresponding to the pathophysiological foundation. The evolution rules with time and those in space can be helpful to decide the clinical stage and pathophysiological phase of infarction, and to provide the evidence in guiding the treatment or judging the prognosis in infarction.
