BACKGROUND:It is confirmed that the characteristics of soft and hard tissue development vary largely in different vertical facial types, which reflect the development trend of the patients and the control ing degree on anchorage.
OBJECTIVE:To evaluate the influence of different vertical facial types on the aesthetic evaluation of facial profiles in young females, and analyze the perception of facial attractiveness from different people.
METHODS:Three beautiful females, with high, average and low mandibular angle, respectively were selected according to the measurement data of projection and the orthodontist’s aesthetic appreciation. They were yel ow race, bilateral facial appearance was basical y symmetrical, and no other maxil ofacial disease was found. They also received no orthodontic or orthognathic treatment. The profile digital photographs and cephalograms of three females were col ected. The positions of soft tissue lip and soft tissue chin were altered incremental y with Dolphin Imaging and Management software. Twenty-five new pictures were generated by the smal scale (2 mm per unit) modification in the sagittal direction. By using“acceptable facial appearance”as a filter, 15 orthodontists selected 11 from 25 pictures. Fifty parents of orthodontic patients, 50 orthodontic patients, and 50 amateurs were taken as the evaluators for subjective aesthetic ratings and for the assessment of the influence of vertical facial types on the facial profile attractiveness.
RESULTS AND CONCLUSION:With low and average angle, straight profile, slightly protrude chin was perceived to be beautiful. With high angle, straight profile, slightly protrude profile was perceived to be beautiful, and evaluation results are consistent between men and women. Evaluators are in agreement when it comes to evaluating the perception of facial attractiveness of three different vertical facial types profile in young females. They also have certain difference in aesthetic tendencies, but when it comes to straight profile they share the same preference. Although different vertical facial types profile has an impact on the profile of lip and chin, but it can’t represent the aesthetic preference of al evaluators.
6.Effects of CP154526,the corticotropin releasing hormone receptor 1 antagonist,on rat hippocampal neuron apoptosis
Chinese Pharmacological Bulletin 2015;(4):504-508,509
Aim To investigate the effects of CP1 54526,a corticotropin releasing hormone (CRH) receptor 1 antagonist,on the hippocampal neuron ap-optosis.Methods Rat hippocampal neurons were primarily cultured.Cell viability was estimated using MTT assays.Neurons were randomly divided into four groups:Normal cultures (Control);CRH-exposed cul-tures (CRH);CRH and CP1 54526 co-exposed cul-tures (CRH + CP ); CP1 54526-exposed cultures (CP).Cell apoptosis was examined by TUNEL or flow cytometry Annexin Ⅴ-PI staining.The protein levels of Bax,Bcl-2 and Caspase-3 were investigated by West-ern Blotting.Results 1 0 -8 mol·L -1 CRH decreased cell viability of cultured hippocampal neuron (P <0.05),while 50 mmol ·L -1 CP1 54526 significantly increased neuron viability (P <0.05).Compared with Control group,cell apoptotic rate,the ratio of Bax and Bcl-2 and the protein level of Caspase-3 were elevated in hippocampal neuron induced by CRH.Combined with CP1 54526 reversed the effects of CRH.Applica-tion of CP1 54526 alone had no obvious effects on cell apoptosis.Conclusions A certain concentration of CRH can induce hippocampal neuron apoptosis,and its receptor 1 antagonist CP1 54526 can effectively re-duce the apoptosis and play a neuroprotective role.

Objective: To explore the burden of spouse caregivers of patients with dementia at home and factors having influence.Methods:Forty-two patients with dementia were collected from psychiatric out-clinic consecutively. Trained investigators did home visit to collect data on severity of the disease (CDR, MMSE), pathological behavior (BEHAVE-AD), activity of daily living (ADCS-ADL) and burdens of their spouse as caregiver (CBI). The caregivers' anxiety, depression (Zung's Anxiety Scale and Depression Scale) and knowledge about dementia were also collected.Results:The caregivers felt big burden (BDI total score: 30.7?15.1). Nearly half of them (42.9%) were in depression and one quarter (23.8%) were anxious. They were lack of knowledge about dementia and unskillful in care-giving. 26.2% caregivers thought dementia is curable or equal to normal aging, 57.1% of them did not believe it is an improving disease. The burden of caregivers was correlated positively with pathological behavior of patients (r=0.40, P

China is entering into an aging society, and the incidence of hypertension and atherosclerosis were increased year by year. The incidence of transient ischemic attack (TIA) patients with carotid stenosis increased year by year. Carotid artery stenosis or occlusion can cause reduction of local brain tissue perfusion resulting from TIA. CT cerebral perfusion imaging and SPECT could detect earlier the chronic hyper fusion of carotid stenosis TIA, forecast risk coefficient and intervention and prevent the occurrence of cerebral infarction, to evaluate effect of carotid endarterectomy and carotid s carotid artery stenting. It is very important to monitor cerebral hemodynamic changes. The technology has the features of blood infusion situation, advantages, curative effect evaluation and development trend in carotid stenosis TIA reviewed by CT perfusion imaging and SPECT.

Polymorphonuclear neutrophil leukocyte (PMN) is an important member of the human immune cells. Recentyears, the recognition of the PMN function and the relationship between PMN and periodontitis have been updated. Besidesthe pathogens killing and phagocytosis, PMN also play an important role in immunoregulation and proresolving. The maintaining of PMN homeostasis is an intricate process and the precondition of defense function, which involves activation, adhesion, recruitment, apoptosis and efferocytosis. The regulatory mechanism of PMN homeostasis called neutrophil rheostat, it works through several cytokines and cells. Any factors that break the homeostasis will result in the damage of host immunity,and may relate to the occurrence of periodontitis. Moreover, PMN dysfunction, because of host factors or microorganism factors, is closely related to periodontitis, especially those associated with systemic diseases and gene defect.
