Objective To explore the effect of personality characteristics on the facial esthetic satisfaction of edentulous patients,in order to provide reference for improving esthetic satisfaction after complete denture restoration.Methods Twenty-two edentulous sub-jects were randomly selected.Before complete denture treatment,the emotional stability of patients was assessed by Eysenck personality questionnaire N scale score(EPQ-N).Before and three months after treatment,patients completed the orofacial esthetic questionnaire,and 3D stereophotogrammetry was performed to evaluate the changes in facial appearance.In addition,multiple linear regression model was established by using N scale score,changes in facial appearance and facial esthetic satisfaction score.Results After complete denture treatment,the difference in the ratio of the middle and lower parts of the face between patients and the normal group was re-duced by(3.85±2.63)%,and the difference of the nasolabial angle between patients and the normal group was reduced by(6.66°±5.39°).The multiple linear regression model showed that N scale score and changes of the differencein the facial proportion between edentulous subjects and normal population were influencing factors of patients'esthetic satisfaction on the facial appearance,and the N scale score and changes of the difference inthe nasolabial anglebetween patients and normal population were influencing factors of the patients'aesthetic satisfaction on the facial profile.Moreover,the effect of two independent variables(N scale score and facial soft tissue change)on the aesthetic satisfaction of facial appearance and facial profile was statistically significant(P＜0.001).Furthermore,when the N score increased,the patients'aesthetic satisfaction on the facial appearance and facial profile decreased(B＜0).Conclusion Personality can affect the aesthetic satisfaction of edentulous patients.Consequently,we should take reasonable measures for patients with different personality in the process of complete denture restoration,so as to achieve the goal of improving patients'aesthetic satisfaction.

Objective:To analyze the clinical efficacy and prognostic factors of comprehensive treatment for atypical teratoid / rhabdomyoma tumor (AT/RT).Methods:Clinical data of children diagnosed with AT/RT who underwent radiotherapy in Department of Oncology of Xinhua Hospital affiliated to Shanghai Jiao Tong University School of Medicine from November 2012 to September 2022 were retrospectively analyzed. Pearson Chi-square test or continuous-corrected Chi-square test or Fisher's exact probability method were used for inter-group comparison of categorical variables. Independent sample t-test or Wilcoxon rank-sum test were used for inter-group comparison of continuous variables. Kaplan-Meier method was used to calculate the 1-year and 2-year overall survival (OS) rate and progression free survival (PFS) rate. Univariate and multivariate Cox regression analyses were employed to determine relevant prognostic factors. Results:A total of 45 patients were included, with a male/female ratio of 1.65:1, including 27 children aged ≥3 years old. All patients received surgery and radiotherapy in which 39 patients received chemotherapy, 41 craniospinal irradiation (CSI), and 4 whole brain or focal radiation therapy. The median follow-up was 28 (13.5, 49) months. A total of 14 patients died after comprehensive treatment. The 1-year OS rate was 80.0% and the PFS rate was 71.1%. The 2-year OS rate was 75.5% and the PFS rate was 65.7%. Survival prognostic analysis showed negative imaging assessment after radiotherapy ( HR=0.087, 95% CI: 0.011-0.697, P=0.022) was a favorable factor for PFS. The primary tumor<4.8 cm ( HR=0.221, 95% CI: 0.052-0.935, P=0.040) and CSI ( HR=0.085, 95% CI: 0.011-0.651, P=0.018) were favorable factors for OS. In subgroup analysis, CSI also improved OS in children aged ≥3 years ( HR=0.014, 95% CI: 0-0.470, P=0.017), but there was no significant difference in PFS. In children without cerebrospinal fluid dissemination, negative radiographic results after radiotherapy ( HR=0.066, 95% CI: 0.009-0.481, P=0.007; HR=0.076, 95% CI: 0.008-0.695, P=0.024, respectively) and CSI (HR=0.105, 95% CI: 0.012-0.937, P=0.044; HR=0.054, 95% CI: 0.005-0.629, P=0.020, respectively) were favorable factors for PFS and OS in children, and the primary tumor<4.8 cm also suggested a longer OS ( HR=0.094, 95% CI: 0.013-0.690, P=0.020). Conclusions:Comprehensive treatment including radiotherapy improves clinical prognosis of children with AT/RT. Our study shows that negative imaging results after radiotherapy are associated with PFS improvement. The primary tumor<4.8 cm and CSI are favorable factors for OS. CSI is also a significantly positive prognostic factor in children aged ≥3 years and those without cerebrospinal fluid dissemination.

Objective:To analyze post-discharge coping difficulty of delivery women based on social ecosystem theory.Methods:From March to May 2022, 23 delivery women from Affiliated Hospital of Guilin Medical University were selected as research objects by the purpose sampling method. The phenomenological research method was used to conduct face-to-face semi-structured interview. The content analysis method was used to analyze the data and extract the theme.Results:A total of 3 themes and 11 sub-themes were extracted. The micro level included 1 theme, namely care stress and self recovery problems coexist, including difficulty in breastfeeding, feeling powerless to raise children, anxiety, disturbance in body recovery of delivery women, prominent sense of sleep deprivation, insufficient knowledge of infant care and body recovery. The mesoscopic level included 1 theme, namely changes in life atmosphere, including caregiver relationship conflict, lack of family support and sense of connection. The macro level included 1 theme, namely interaction of social environment, including living environment not meeting expectations, sense of economic burden, expectation of instant professional guidance.Conclusions:The post-discharge coping difficulty of delivery women is complex and varied. Medical staff should use information technology, family synchronous empowerment, social worker intervention and other methods to meet the needs of delivery women, reduce their post-discharge coping difficulties.

The purpose of this study was to understand the effect of gender on the traits of wool. One-year-old male and female Chinese merino sheep (JunKen type) were used to screen differentially expressed proteins in skin tissues by quantitative proteomics using liquid chromatography-tandem mass spectrometry (LC-MS/MS) and data independent acquisition (DIA) strategy. This was followed by GO function annotation, KEGG metabolic pathway and protein network interaction analysis on the differential proteins obtained. The result showed that there were 674 differentially expressed proteins between male and female groups, whereas 280 proteins were up-regulated and 394 proteins were down-regulated in the male group. Through further comparison and analysis, there were 43 differentially expressed proteins related to skin hair follicle development and wool phenotype, 30 up-regulated and 13 down-regulated. The GO annotation analysis of differentially expressed proteins were mainly enriched in 37 processes of molecular function such as oxygen binding, chondroitin sulfate binding, heme binding, glutathione peroxidase activity and glutathione transferase activity; 120 biological processes such as cellular oxidant detoxification, regulation of muscle contraction, notch signaling pathway, calcium ion transmembrane transport and glutathione metabolism; and 31 processes related to cellular components such as mast cell granule, nucleus, sarcoplasmic reticulum and endoplasmic reticulum lumen. KEGG analysis showed that the differentially expressed proteins were involved sixteen signaling pathways, among which MAPK and p53 signaling pathways were closely related to wool growth and development. The protein network interaction analysis discovered that COL1A1 was closely related to MMP2, SPARC, THBS1 and other differentially expressed proteins, which might play a key role in wool growth and development. Thus, this study obtained basic data for revealing the molecular mechanism of sheep wool traits of different gender.

Objective:To investigate the efficacy of CT imaging features in evaluating occult peritoneal metastasis (OPM) of diffuse infiltrating gastric cancer (Borrmann Type Ⅳ).Methods:Totally 101 patients with locally advanced Borrmann type Ⅳ gastric cancer were retrospectively collected who were admitted to Peking University Cancer Hospital from March 2014 to March 2021. The patients were divided into OPM group (53 cases) and the non-OPM group (48 cases) according to the results of preoperative CT and laparoscopic exploration/peritoneal cytology examination. The pathological examination results were recorded, including the degree of histological differentiation and Lauren classification. The evaluation indicators included the tumor center position, the number of tumor-occupied portions, involved orientation, mucosal broadband sign, stratified enhancement, serosa invasion, increased density of peripheral fat tissue, and enlarged lymph nodes. The maximum thickness of the primary tumor, average CT value of the primary tumor (arterial phase, venous phase, and delayed phase), difference between venous phase and arterial phase, difference between delayed phase and venous phase, and pattern of the enhanced curve were recorded. The Mann-Whitney U or Chi-square test was used to compare the differences of pathological and CT features between two groups. The multivariate logistic regression was used to screen independent predictors and establish a nomogram. The receiver operating characteristic curve was used to evaluate the performance of the nomogram in predicting OPM, and the Hosmer-Lemeshow test was used to test the model′s goodness of fit. Results:There was statistical significance in the seven indicators between the OPM and non-OPM groups, including tumor-occupied portions of stomach, mucosal broadband sign, stratified enhancement, serosa invasion, increased density of peripheral fat tissue, the enhanced curve pattern and the degree of histological differentiation ( P<0.05). Among them, the degree of histological differentiation (OR=0.19, P=0.033), stratified enhancement (OR=7.02, P=0.005) and serosa invasion (OR=14.27, P<0.001) were independent predictors of OPM. The nomogram was established based on the three significant features. The area under the curve for predicting OPM was 0.826 (95%CI 0.745-0.908), the sensitivity was 0.566 and the specificity was 0.938. The Hosmer-Lemeshow test showed a good agreement between the OPM risk predicted by the nomogram and the actual risk ( P=0.525). Conclusions:The CT features of Borrmann type Ⅳgastric cancer complicated with OPM have specific characteristics. The diagnosis model based on the degree of histological differentiation, stratified enhancement, and serosa invasion had high efficacy in evaluating OPM.

The general data, blood routine, liver and kidney function, glucose metabolism and lipid metabolism of 11 922 participants who underwent physical examination at the Health Management Center of the Second Xiangya Hospital of Central South University from January 2019 to December 2019 were collected. Clinical characteristics and independent factors of patients with discordance between HbA1c and FPG were evaluated and analyzed. The prevalence of HbA1c-defined diabetes and prediabetes (respectively 8.13%, 34.79%) were significantly higher than that in FPG-defined diabetes and prediabetes (respectively 4.70%, 8.97%) (χ2=2 635.940; P<0.001). The prevalence of inconsistence between HbA1c and FPG was 35.65% and increased with increasing age. This inconsistence mainly occurred in population with HbA1c:5.7%-6.0% and FPG<5.6 mmol/L, followed by population with HbA1c:6.1%-6.4% and FPG<5.6 mmol/L. The risk factors of inconsistency included advanced age, overweight or obesity, hypoalbuminemia, dyslipidemia and hyperuricemia. Among these special participants, compared with participants under 45 years old, participants with over 45 years of age ( OR=3.525, 95% CI: 3.216-3.863, P<0.001) were more likely to have inconsistence between HbA1c and FPG; and overweight participants ( OR=1.474, 95% CI: 1.341-1.620, P<0.001) or obese participants ( OR=1.856, 95% CI: 1.633-2.110, P<0.001) are prone to have the inconsistence than those with normal weight.

Objective:To investigate the effect of adenosine deaminase acting on RNA 1 (ADAR1) on 5-serotonin-2c receptor in alleviating aggression in socially isolated mice.Methods:Sixty healthy male BALB / c mice aged 21 days were randomly divided into six groups: social isolation group, social control group, ADAR1 inducer social isolation group, ADAR1 inhibitor social isolation group, ADAR1 inducer social control group and ADAR1 inhibitor control group.The mice fed in single cage for 4 weeks were used as social isolation model while the mice fed in group were used as control group.ADAR1 inducer (5.0×10 4 U/kg) and inhibitor (10 mg/kg) were given intraperitoneally to mice in the ADAR1 inducer social isolation group and the ADAR1 inhibitor social isolation group respectively.The aggressive behavior of mice was evaluated by resident-intruder test.The expression of ADAR1 and 5-serotonin-2c receptors in the brain of mice was detected by immunohistochemistry and Western blot. Results:The attack latency of social isolation group was significantly lower than that of social control group ((43.15±6.99) s, (542.40±30.50) s; t=15.906, P<0.01), and the latency of attack ((256.70±29.49) s) in the ADAR1 inducer social isolation group was significantly higher than that in the social isolation group ( t=7.046, P<0.01). The latency of attack ((15.25±2.18)s) in the ADAR1 inhibitor social isolation group was significantly lower than that in the social isolation group ( t=3.809, P<0.01). The optical density of ADAR1 immunoreactive cells in the amygdala of the social isolation group mice was significantly lower than that in the corresponding brain area of the social control group (BLA: (0.038±0.002), (0.074±0.004); LaDL: (0.033±0.002), (0.060±0.002); LaVM: (0.045±0.003), (0.073±0.004); Lavl area: (0.044±0.003), (0.070±0.003); t=8.428, 9.037, 6.462, 5.698, all P<0.01). The optical density of ADAR1 immunoreactive positive cells in the amygdala (BLA: (0.060±0.003), LaDL: (0.042±0.002), LaVM: (0.056±0.004), Lavl: (0.054±0.003) in the ADAR1 inducer social isolation group was significantly higher than those in the corresponding brain area of the social isolation group mice ( t=6.055, 2.876, 2.312, 2.492; all P<0.05). The expression of ADAR1 protein and 5-serotonin-2c receptor protein in amygdala of social isolation group were significantly lower than those of social isolation group ( t=11.37, 12.65; P<0.01). The expression of ADAR1 protein and 5-serotonin-2c receptor protein in the amygdala of the ADAR1 inducer social isolation group were significantly higher than those of the social isolation group ( t=3.02, 4.401; P<0.05). Conclusion:ADAR1 inducer alleviates the aggressive behavior of social isolated BALB / c mice by enhancing the protein expression of 5-serotonin-2c receptor in the amygdala of social isolated BALB/c mice.

Objective To explore the effects of ADAR1 inducer and inhibitor on cognition and ADAR1 expression of isolated BALB/c mice.Methods Sixty healthy BALB/c mice were divided into 6 groups according to randomized design with 10 animals each group,the gregarious control group (GH),social isolation model group (SI),ADAR1 inducer treated gregarious group (GH+IFN-γ),ADAR1 inhibitor treated gregarious group (GH+EHNA),ADAR1 inducer treated isolation group (SI+IFN-γ) and ADAR1 inhibitor treated isolation group (SI+EHNA).Mice in drug treatment groups were treated with ADAR1 inducer (5.0? 104 U/kg,20 ml/kg,ip) and inhibitor (10 mg/kg,20 ml/kg,ip).Objection recognition test was used to measure cognition.Immunohistochenmistry was used to measure ADARI immunoreactivity and Western blotwas used to measure ADAR1 protein expression.Results In the objection recognition test,the non-spatial discrimination index of mice in SI group (-0.16±0.09) was significantly lower than that of GH group (0.41 ±0.17,P＜0.01),the non-spatial discrimination index of mice in SI+IFN-γ group (0.20±0.09) and in SI+ EHNA group (-0.29±0.12) was higher (P＜0.01) and lower (P＜0.05) than that of the SI group respectively.The immunohistochemistry results showed that the ADAR1 immunoreactivity in hippocampus of mice in SI group (Hilus:(0.013±0.003),CAI:(0.021±0.005)) decreased significantly compared to those of GH group(Hilus:(0.021 ±0.002),(0.047±0.004);both P＜0.05).And GH+IFN-γgroup mice showed increased ADAR1 immunoreactivity obviously in Hilus ((0.013±0.003) vs (0.023±0.004),P＜0.01) and in CA1 ((0.021±0.005) vs (0.040±0.005),P＜0.01) compared with that of SI group,ADAR1 inducer recovered the above abnornal ADAR1 immunoreactivity.Western blot results showed that the ADAR1 protein expression of mice in SI group (0.48 ±0.07) in hippocampus was significantly decreased (P＜0.01) compared to that of GH group (1.00 ±0.00).The level of ADAR1 protein in SI+IFN-γgroup(0.82 ±0.04) increased compared with that of SI group.Conclusions Four weeks of social isolation can reduce the non-spatial cognitive ability of BALB/c mice and decrease the expression of ADAR1 in the hippocampus.The ADAR1 inducers and inhibitors can reverse and aggravate the cognitive impairment caused by social isolation respectively.The related mechanisms may be related to the expression of ADAR1.

Ovine somatic cell nuclear transfer (SCNT) efficiency remains lower. Therefore, we optimized the program before oocyte enucleation on ovine SCNT. Four experiments were done including exposure duration of ovaries (3 h or 3 to 5 h), duration of oocytes maturation (18 h and 24 h), rate of donor adherent and enucleation time of maturate oocyte. The maturation rates of oocyte, fusion rates and cleavation rates of cloned embryos were used to assess the efficiency of different procedures. The maturation rates of ovaries with 3 h exposure was higher than that of 3 to 5 h (60.18% vs 52.50%) (P<0.05). Embryonic development competence had no significant difference (P>0.05). The maturation rates were significantly different between group18 h and 24 h (53.81% vs 89.06%, P<0.01). Embryonic development competence had no significant difference (P>0.05); fusion rates of donor adherent 30% group was higher than that of 10% group. Embryonic development competence had no significant difference (P>0.05). Different adherent donor characterizes the difference in plateau phase. The cleavation rates of 18 hpm group was higher than that of 16 hpm group. Embryonic development competence had no significant difference (P>0.05), the enucleation of 16 hpm group obtained one clone fetus, we got four clone fetus to repeat the 16 hpm group. Five microsatellite was analyzed by PAGE, the bands indicated that fingerprint of cloned fetus were completely the same as those of donor cells. Our data therefore suggests program optimization before enucleation assurance quality of material which be able to improve the quantity and quality of clone embryos, and optimized scheme can obtain clone sheep offspring.
