Objective To compare the effectiveness and safety of ultra-early (< 24 h)and delayed (≥ 24 h ) endovascular embolization of ruptured intracranial aneurysms with systematic review. Methods PubMed,Embase,the Cochrane Library,VIP,Wanfang Data,and China National Knowledge Internet (CNKI)were retrieved according to inclusion,exclusion criteria and retrieval strategies,and the clinical literature of ultra-early and delayed endovascular embolization for the treatment of ruptured intracranial aneurysms were obtained. The Review Manager 5. 3 software was used to conduct Meta-analysis for good prognosis rate,postoperative mortality,and postoperative rebleeding rate. Results A total of 10 articles were included,9 of them were retrospective control studies and 1 was prospective control study. A total of 2 021 patients were enrolled,including 970 patients treated with ultra-early treatment;1 051 patients treated with delayed treatment. There was significant difference in the good prognosis rate (OR,2. 67,95% CI 2. 07 -3. 44,P < 0. 01)and the postoperative rebleeding rate (OR,0. 23,95% CI 0. 11 -0. 47)between the ultra - early embolization group and the delayed embolization group (all P < 0. 01). There were no significant difference in the mortality between the two groups (OR,0. 76,95% CI 0. 51 -1. 13,P = 0. 17). The subgroup analysis showed that there were significant differences in the good prognosis rate in the ultra-early group compared with the early group (< 3 d,OR,1. 98,95% CI 1. 33 -2. 95)and the middle and late group (≥3 d,OR,4. 66,95% CI 2. 21 -9. 81,all P < 0. 01). Conclusion Compared with the delayed group, ultra-early embolization of ruptured intracranial aneurysms may improve the good prognosis rate,reduce the rebleeding rate,and not increase the mortality after procedure at the same time. However,more high quality and large sample randomized controlled trials are needed to confirm them.

The identity of higher-order neurons and circuits playing an associative role to control renal function is notwell understood.We identified specific neural populations of rostral elements of brain regions that project multisynaptically to the kidneys in 3~ days after injecting a retrograde tracer pseudorabies virus (PRV)-614 into kidney of 13 adult male C57BL/6J strain mice.PRV-614 infected neurons were detected in a number of mesencephalic (e.g.central amygdala nucleus),telencephalic regions and motor cortex.These divisions included the preoptic area (POA),dorsomedial hypothalamus (DMH),lateral hypothalamus,arcuate nucleus (Arc),suprachiasmatic nucleus (SCN),periventricular hypothalamus (PeH),and rostral and caudal subdivision of the paraventricular nucleus of the hypothalamus (PVN).PRV-614/Tyrosine hydroxylase (TH) double-labeled cells were found within DMH,Arc,SCN,PeH,PVN,the anterodorsal and medial POA.A subset of neurons in PVN that participated in regulating sympathetic outflow to kidney was catecholaminergic or serotonergic.PRV-614 infected neurons within the PVN also contained arginine vasopressin or oxytocin.These data demonstrate the rostral elements of brain innervate the kidney by the neuroanatomical circuitry.

OBJECTIVETo explore the procedures of dynamic infusion cavernosometry and cavernosography (DICC) and their application in the diagnosis and classification of venous erectile dysfunction (VED).

METHODSThis study included 103 ED patients, aged 20 to 43 years, highly suspected of VED, with disease courses of 4 months to 6 years. DICC was performed and analyses were made on the results, especially the parameters of flow-to-maintain (FTM) and pressure decay (PD) in the corpus cavernosum.

RESULTSBased on the parameters of FTM and PD, 21 of the patients were normal, 5 were suspected of VED, 39 had mild VED, 25 had moderate VED, and 13 had severe VED. Penile subcutaneous hematoma was found in 4 of the patients, all recovered after 3 to 5 days, with no other complications.

CONCLUSIONDICC is a reliable, safe and minimally invasive method for the diagnosis and classification of VED.

Objective To study the correlation of ~(18)F-fluorodeoxyglucose (FDG) PET/CT with pathological changes of the VX2 rabbit tumors after treatment of Ar-He knife,and to explore the evolution of the Ar-He knife curative effect for VX2 rabbit tumors.Methods Thirty-six Japanese white rabbits had successfully been implanted with VX2 tumors in thighs.Four weeks later,the rabbits with VX2 tumors were imaged with FDG PET/CT before they were treated with Ar-He cryoablation.The rabbits were evenly and randomly divided into 6 groups (6 rabbits in each group) and imaged with FDG PET/CT respectively on the first day,third day,seventh day,fourteenth day,thirtieth day and sixtieth day after cryoablation.The rabbits in each group were sacriftced after post-treatment FDG PET/CT imaging for pathology and immunohistochemistry studies.The standardized uptake value (SUV) of tumor regions were calculated and compared with pathology and immunohistochemistry findings in the cryoablative area in each group.Paired-samples t-test and bivariate correlation analysis were evaluated by statistical software SPSS 16.0.Results After ArHe cryoablation,pathological changes of "necrosis-inflammatory response→organization" were found.On CT imaging,the tumors enlarged during 3-14 d after treatment and then shrank gradually.On FDG PET imaging,the maximum SUV (SUV_(max)) dropped dramatically on the first day after the operation(from 2.54±1.12 to 0.67±0.12),and increased slightly on the third day (1.71±0.82),and then continually dropped to 0.51±0.32 (60 d afterthe operation).The differences of SUV_(max) between pre-and after cryoablationin each stage were significant,respectively (t=5.471,8.716,11.388,5.713,7.144 and 7.213,all P＜0.05).The size and SUV_(max) of the targeting area did not correlate with each other(r=0.259,P=0.675).The change of the MVD closely correlated with SUV_(max)(r=0.865,P=0.032).Conclusion FDG PET/CT can reveal the pathological change of tumor tissue after Ar-He cryoablation therapy and therefore may be a potential tool for evaluating the curative effect of this treatment modality.

AIM:To explore the association of the mutation in PPP2R3A exons and retinoblastoma.METHODS:Hospital-based case control study was taken.Retinoblastoma patients (15 cases, as case group) and matched controls (30 controls, as control group) were recruited in this study.Genomic DNA obtained from formalin fixed paraffin embedded (FFPE) and peripheral blood were used as template.PPP2R3A gene exon sequences were detected by PCR-sequencing.Homology analysis was performed using blastn in GenBank.RESULTS:Analyzing PPP2R3A DNA sequences (1001bp) from 15 cases, two reported SNPs had been detected, including rs34629706 and rs144802055.Rs34629706 also occurred in the control group.Rs144802055 appeared only in the case group.CONCLUSION:PPP2R3A gene SNPs of rs34629706 is unrelated to the incidence of retinoblastoma.Relations between rs144802055 and RB needs to be further explored.

Objective To investigate the effects of quetiapine and risperidone in the treatment of behavior and psychiatric symptom of dementia(BPSD).Methods 56 cases of Alzheimer's disease and vascular dementia pa- tients were all met for the classification and diagnostic criteria for mental illness in China(CCMD-3)and randomly divided into two groups(27 in quetiapine group,29 in risperidone group),experimental dosage were 0.05～0.3g/d and 1～2mg/d,respectively.The treatment lasted for 8 weeks.Results The total efficiency of quetiapine was 66.67% and that of risperidone was 65.5%,and the statistical difference was significant.As for the adverse effects, there was no significant difference,but incidence of EPS in quetiapine group was less than that of risperidone group. Conclusion Quetiapine can be widely administrated in clinic application as the high efficacy of control BPSD with low minor adverse effect.

Objective: To investigate the effect of insulin-like growth factor-Ⅰon osteocalcin secretion in periodontal ligament cells. Methods: Human periodontal ligament cells were cultured by tissue explant in vitro, and the concentration of osteocalcin were determined with radio-immunological method. Results: Under the condition of L-ascorbic acid and β-glycerophosphate in culture medium, human periodontal ligament cells secreted osteocalcin time-dependently and peaked at the third week; IGF-Ⅰ3.125 ng/ml，6.250 ng/ml, 12.500 ng/ml, 25.000 ng/ml could promote the secretion of osteocalcin dose dependently. Conclusion: IGF-Ⅰ can increase the secretion of osteocalcin in human periodontal ligament cells.

OBJECTIVETo investigate the feasibility of applying harmonic scalpel in tonsillectomy by comparing it with the conventional tonsillectomy.

METHODSThirty-five patients were treated by harmonic scalpel assisted tonsillectomy (harmonic scalpel group) and 35 patients were treated by conventional tonsillectomy (control group). The operating time and blood loss during operation and the degree of pain and post-tonsillectomy hemorrhage as well as the time of defining were observed.

RESULTSThe data of the operating time and blood loss during operation and the degree of pain in harmonic scalpel group were lower than that in the conventional group, the harmonic scalpel group had less perioperative bleeding (median 1 ml), short operation time (median 20 min), postoperative pain during 5 days with visual analogue scale was lighter (median from 5 scores down to 1 score), there was statistical difference (P < 0.01). Neither primary hemorrhage nor secondary hemorrhage occurred in harmonic scalpel group, while one primary hemorrhage and one secondary hemorrhage occurred in conventional group. No difference was found in the beginning time of defining (P > 0.05).

CONCLUSIONThe application of harmonic scalpel in tonsillectomy was safe, efficient and feasible, which had a nice application prospect in the field of otolaryngology.
