Objective:To understand the status quo of emotional intelligence, emotional labor, and humanistic caring ability of medical staff, and to clarify their internal relationship.Methods:Convenience sampling was used to select 713 medical staff from a grade A tertiary hospital in Chengdu, Sichuan Province, China. Emotional Intelligence Scale, Humanistic Caring Scale, and Emotional Labor Scale were used to measure the emotional intelligence, humanistic caring ability, and emotional labor of medical staff. SPSS 22.0 software was used to establish a database for statistical description and analysis. Process 3.2 software was used to analyze the mediating effect.Results:In humanistic caring ability, the average score of comprehension dimension was the highest (75.62±8.20) and the average score of patience dimension was the lowest (58.53±5.01). In emotional labor, the average score of the deep action dimension was the highest (23.39±3.85) and the average score of the surface action dimension was the lowest (17.73±3.18). In emotional intelligence, the average score of self-emotion evaluation dimension was the highest (21.76±3.30) and the average score of other-emotion evaluation dimension was the lowest (20.07±3.71). Positive correlations were found between humanistic caring ability and emotional intelligence, between humanistic caring ability and emotional labor, and between emotional intelligence and emotional labor ( P<0.01). Humanistic caring ability had a partial mediating effect between emotional intelligence and emotional labor. Humanistic caring ability had direct and indirect effects on emotional labor, and the effect sizes were 0.279 and 0.029, respectively. Conclusion:Emotional intelligence has a direct positive predictive effect on emotional labor, humanistic caring ability as an intermediary variable indirectly and positively predicts emotional labor. Humanistic caring ability plays a partial mediating role between emotional intelligence and emotional labor. Attention should be paid to the emotional labor of medical staff, and the emotional labor of medical staff should be improved through targeted training on emotional intelligence and humanistic caring ability. These efforts will improve the current situation and establish a harmonious doctor-patient relationship.

Methods:Two thousand standard sections images werre collected from 2 000 clinical retrospective pediatric hip ultrasound videos from January 2019 to January 2021. All standard sections were annotated by the annotation team through the self-designed software based on Python 3.6 environment for image cross-media data annotation and manual review standardization process with unified standards. Among them, 1 753 were randomly selected for training the deep learning system, and the remaining 247 were used for testing the system. Further, 200 standard sections were randomly selected from the test set, and 8 clinicians independently completed the film reading annotation. The 8 independent results were then compared with the AI results.Results:The testing set consists of 247 patients. Compared with the clinician's measurements, the area under the receiver operating characteristic curve (AUC) of diagnosing hip joint maturity was 0.865, the sensitivity was 76.19%, and the specificity was 96.9%. The AUC of AI system interpretation under Graf detailed typing was 0.575, the sensitivity was 25.90%, the specificity was 89.10%.

The 95% LoA of β-angle, of -7.7191 to 6.8777 ( Bias -0.42, P=0.077). Compared with those from 8 clinicians, the results of AI system interpretation were more stable, and the β-angle effect was more prominent. Conclusion:The AI system can quickly and accurately measure the Graf correlation index of standard DDH ultrasonic standard diagnosis plane.

Objective:To explore the application effect of family-centered empowerment model (FCEM) in rehabilitation nursing of children with femoral shaft fractures treated by skin traction.Methods:A retrospective case-control study was conducted to analyze the clinical data of 107 children with femoral shaft fractures treated with skin traction in Anhui Children′s Hospital from April 2019 to October 2021, including 67 males and 40 females; aged 1.5-5.0 years [2.8(2.0, 3.5)years]. Fracture types included oblique fracture ( n=50), comminuted fracture ( n=26), transverse fracture ( n=14) and spiral fracture ( n=17). FCEM nursing was implemented in 55 patients (family empowerment group) and routine home rehabilitation nursing guidance was performed in 52 patients (routine nursing group). The face, legs, activity, cry, consolability (FLACC) behavioral score on admission and at days 1, 3 and 7 after skin traction, treatment compliance rate at 1 month after skin traction, complication rate at 1 month after skin traction, length of hospital stay and fracture healing time were compared between the two groups. Results:All patients were followed up for 12-18 weeks [13.4(12.7, 13.9)weeks]. There was no significant difference in FLACC behavioral score between the two groups on admission ( P>0.05). The FLACC behavioral score was (4.0±0.7)points,(3.4±0.6)points and (2.4±0.6)points in family empowerment group at days 1, 3 and 7 after skin traction, lower than (4.8±0.7)points, (3.9±0.8)points and (3.3±0.5)points in routine nursing groups (all Ρ<0.01). One month after skin traction, treatment compliance was excellent in 51 patients, good in 4, poor in 0, with treatment compliance rate of 92.7% (51/55) in family empowerment group, and was excellent in 40 patients, good in 9, poor in 3, with treatment compliance rate of 76.9% (40/52) in routine nursing group ( Ρ<0.05). The complication rate was 5.4% (3/55) in family empowerment group, lower than 21.2% (11/52) in routine nursing group ( Ρ<0.05). The length of hospital stay and fracture healing time were (15.6±0.3)days and (7.1±0.8)weeks in family empowerment group, shorter than (16.8±0.3)days and (8.2±0.4)weeks in routine nursing group (all Ρ<0.01). Conclusion:For children with femoral shaft fractures treated by skin traction, nursing using FCEM can alleviate pain, improve treatment compliance, reduce complication rate, reduce hospital stay and shorten fracture healing time.

Objective To investigate the association of rs523349(V89L),rs9282858(A49T)and TA repeat polymorphisms in testosterone 5-alpha-reductase Ⅱ(SRD5A2) gene with prostate cancer(PCa) in the population of Yi nationality in Yunnan Province. Methods Sanger sequence detection technique was used to detect rs523349(V89L),rs9282858(A49T)and TA repeat polymorphisms of SRD5A2 gene in 122 subjects with confirmed PCa and 135 age-matched healthy controls in the Yunnan Yi population,then the association of these polymorphisms with prostate cancer was analyzed. Results The AA genotype of rs9282858 site in SRD5A2 gene was not found between the Pca patients and the healthy controls in the Yunnan Yi population. The genotypic and allelic frequency distributions of rs523349 and rs9282858 were not significantly varied between the Pca patients and the controls(P>0.05). But the genotypic and allelic frequency distributions of TA repeat site were significantly varied(P < 0.05). The genotype containing(TA)9 allele was more common in the Pca patients than the healthy controls(P=0.033). Compared with(TA)0 allele subjects,(TA)9 allele subjects had a higher PCa risk(OR=2.181, 95% CI :1.111~4.281,P=0.021). Conclusion The TA repeat polymorphisms of SRD5A2 gene was associated with PCa risk in the Yunnan Yi population,which could be used as a risk factor to screen the high-risk individuals.

Interactions between chromatin segments play a large role in functional genomic assays and developments in genomic interaction detection methods have shown interacting topological domains within the genome. Among these methods, Hi-C plays a key role. Here, we present the Genome Interaction Tools and Resources (GITAR), a software to perform a comprehensive Hi-C data analysis, including data preprocessing, normalization, and visualization, as well as analysis of topologically-associated domains (TADs). GITAR is composed of two main modules: (1) HiCtool, a Python library to process and visualize Hi-C data, including TAD analysis; and (2) processed data library, a large collection of human and mouse datasets processed using HiCtool. HiCtool leads the user step-by-step through a pipeline, which goes from the raw Hi-C data to the computation, visualization, and optimized storage of intra-chromosomal contact matrices and TAD coordinates. A large collection of standardized processed data allows the users to compare different datasets in a consistent way, while saving time to obtain data for visualization or additional analyses. More importantly, GITAR enables users without any programming or bioinformatic expertise to work with Hi-C data. GITAR is publicly available at http://genomegitar.org as an open-source software.

Objective To investigate the effect of lentivirus carrying shRNA-VDR vector on GLi1 in pros-tate cancer PC-3 cells. Methods The cells were cultured according to the culture conditions of PC-3 cells. Expression of VDR and GLi1 in PC-3 cells was detected by fluorescence quantitative PCR and immunocytochemistry SP method.The efficiency of PC-3 cell virus infection was evaluated.The effect of VDR gene interference and GLi1 transcription level on PC-3 cells was detected by RT-PCR.Results Cell culture,cell status was recorded and PC-3 cells were in good condition and the passages was 4 days. Fluorescence quantitative and immunocytochemi-cal SP showed that VDR and GLi1 were expressed in PC-3 cells.The virus infection efficiency showed that the in-fection efficiency was about 95% when adding LV3-NC lentivirus to PC-3 cells at 1:10 ratio. RT-PCR showed that VDR-shRNA lentivirus successfully disturbed VDR expression and decreased by 85%(P < 0.05)compared with the control group after 72 days of VDR-shRNA lentivirus transfection. Transcription level of GLi1 gene in the experimental group increased by 9% compared with the control group(P < 0.05). The transcription level of GLi1 gene in the experimental group increased by 248% compared with the control group(P < 0.05). Conclusion The cultured PC-3 cells were in good condition. VDR and GLi1 genes were expressed in PC-3 cells. Lentivirus showed highest efficiency in infecting PC-3 at 1:10 ratio. When VDR was disturbed,the expression of GLi1 in-creased.In prostate cancer cells,vitamin D can inhibit the Hh signaling pathway and cause GLi1 expression down expression.

Objective To investigate the correlation of self perceived burden, family cohesion and adaptability in advanced cancer patients. Methods The Chinese version self perceived burden scale (SPBS), Chinese version of family cohesion and Adaptability Scale (FACES-CV) were used to investigate 139 cases of patients with advanced cancer, and to analyze their correlation with family cohesion and adaptability compared with the norm. Results Patients' self perceived burden score (35.83 ± 5.59) points in the moderate level. The 3 dimensions of the item score from high to low was economic burden (4.12 ± 0.86), body burden (3.63 ± 0.53), emotional burden (3.49 ± 0.63); survey of patients with family cohesion and adaptability, intimacy score (67.96 ± 9.35) points, the ideal intimacy score (83.68 ± 6.05), satisfaction score (15.71 ± 9.39) points, were higher than the national norm, the actual adaptability score (48.00 ± 6.92) and ideal adaptability score (56.47 ± 4.99) points lower than the national norm, the difference was statistically significant (P<0.01 or 0.05). Patients' self perceived burden score and intimacy was negatively correlated (r=-0.186, P<0.05), and positively correlated with intimacy satisfaction (r=0.175, P<0.05). Regression analysis, gender (B=0.236, P<0.01), family medical burden (B=0.183, P<0.05), actual family cohesion (B=-0.111, P<0.05) was the influencing factors of patients' self perceived burden. Conclusions The burden of self perception in advanced cancer patients is closely related to family cohesion and adaptability. It is suggested that the medical staff should pay attention to the family psychological intervention and provide emotional connection for the patients and their families, so as to reduce the negative emotion of the patients with advanced cancer.

BACKGROUND:Femoral neck fracture is mainly fixed by three inverted triangle cannulated screws. Scholars have proposed to add a cannulated screw to enhance the fixation strength of femoral neck fracture of Pauwels III type based on three cannulated screw fixation, but the stability is not verified. OBJECTIVE:To analyze the biomechanical stability and stress of the three and four cannulated screws for the treatment of the Pauwels III femoral neck fractures. METHODS:The CT imaging results of the fourth generation of artificial bone sawbones were imported into the Mimics software wherein a three-dimensional finite element model of the proximal femur was prepared and introduced in the 3-matic software. Models of middlesegment of femoral neck with Pauwels III fractures were established. Cannulated screw models were established with UG 8.0 software and introduced in the fractures models. Finally, finite element models of Pauwels III femoral neck fractures fixed with three and four screws were established. In the same condition, an axial load of 411 N was applied on the femoral head with Abaqus software. The displacement of two markers of the broken ends and internal fixation system Von Mises stress distribution were compared between the two models. RESULTS AND CONCLUSION:(1) The displacement was 0.42 mm in three screws model, and 0.17 mm in the four screws model. (2) Von Mises stress peak was 547 MPa and 27.8 MPa in both models. The peak value was lower in models of fourscrews than that of three screws. Stress concentration position was at the fracture site in both models. The stress range of models of four screws was more extensive and scattered. (3) Finite element analysis results demonstrated that four-screw implantation for Pauwels III femoral neck fractures had strong anti-shearing force and biomechanical stability. Clinical advantages need further clinical comparative study.

Objective To evaluate the clinical efficacy of transurethral resection of ureteral orifice invaded by advanced prostate cancer caused hydronephrosis. Methods A retrospective study was done in 15 patients who were diagnosed by advanced prostate cancer with invasion of ureteral orifice and treated by transurethral resection of ureteral orifice and maximal androgen blockade. 24 kidneys were diagnosed as hydronephrosis by ultrasound. Before the procedure, the average serum BUN was 13.2 mmol/L (8.9~28.5), the average serum Cr was 243.3 μmol/L (126.7~369.2), the average GFR evaluated by renal radionuclide imaging was 48.6 mL/min (31.1~66.2), and the upper urinary tract was obstructed in kidneys with hydronephrosis. Results All 15 patients underwent successfully transurethral resection of ureteral orifice and discharged after 4 days stay. The average procedure time was 65 min (50~100 min) and mean blood loss was 45 mL (30~65 mL) . The patients were followed up for 2~4 weeks. Hydronephrosis examined by ultrasound was ameliorated in 18 kidneys (75%) and not obviously changed in 6 kidneys (25%) in one week after procedure. Hydronephrosis examined by ultrasound was ameliorated in 20 kidneys (83.3%) and not obviously changed in 4 kidneys (16.7%) in two weeks after procedure. Within two weeks after procedure,the average serum BUN was 10.75 mmol/L (6.6~21.30 mmol/L), the average serum Cr was 187.3μmol/L (97.5~286.6 μmol/L), the average GFR evaluated by renal radionuclide imaging was 58.1 mL/min (37.8~79.2 mL/min),and upper urinary tract was unobstructed. Conclusion Upper urinary tract obstruction and renal function were ameliorated and improved in a short time by transurethral resection of ureteral orifice invaded by advanced prostate cancer which caused hydronephrosis.

Objective To study the correlation between marital adjustment and personality characteristics in infertile patients. Method The Locke-Wollance marital adjustment measurement scale and Eysenck personality questionnaire(EPQ)were used among 156 patients with infertility to investigate the correlation between marital adjustment and personality characteristics in infertile patients. Results The total score on the marital adjustment was(100.7±15.5). The rate of good marital adjustment was 51.3%and the rate of marital maladjustment was 48.7%. Those with a marital time of shorter than 5 years were better at marital adjustment compared to those with more than 5 years adjustment(P<0.01). In the characteristics of personality,the items of psychoticism(P)and neuroticism(N)fell at the mode of propensity. The scores on introversion and covering were at the middle level. The groups between the marriage age of shorter than 5 years and more than 5 years were significantly different in psychoticism,introversion and extroversion and nervousness(P<0.01). The marital adjustment were negatively correlated with psychoticism and nervousness,but positively correlated with extraversion. The marriage adjnstmc-nt were positively correlated to cpsychoticism and nervousness,but postively correlated with extroversion. The marriage age was positively correlated with psychoticism and nervousness,but negatively related to extraversion and covering with statistically significant difference (P<0.01).Conclusions In the infertile patients,there are many cases of family marriage disorder. The marriage adjustment and age can affect the personality traits of infertile patients. It indicates that infertility affects the physical and mental health.
