Objective:To investigate the characteristics of voice-personality perception in blind persons and its relationship with their self-evaluation of personality.Methods:A total of 68 blind persons and 68 sighted peers were respectively recruited to rated 30 short voice recordings on traits of voice-personality perception(including maturi-ty,sunshine,cuteness,indolence,seriousness,simpleness and honestness,gentleness,kindness,self-confidence and optimism).Meanwhile,data on self-evaluations of the above participants and speakers in those recordings,along with acquaintance's ratings on speakers'personality were collected.Results:The research found that compared to sighted peers,blind individuals had a lower voice-personality rating on speakers in traits of sunshine,seriousness,gentleness,kindness,self-confidence and optimism(Ps＜0.005).It also detected that the voice-personality ratings on these speakers by blind individuals had a greater deviation from the rating by these speakers/acquaintances in sunshine;gentleness;kindness and optimism(Ps＜0.005).Meanwhile,blind individuals had lower self-rating on personality in sunshine and optimism(Ps＜0.005).Furthermore,self-ratings of sunshine from blind individuals were positively associated with their voice-personality ratings of optimism on speakers(r=0.28,P＜0.05),and their self-ratings of optimism were positively related to their voice-personality ratings of sunshine and self-confi-dence on speakers(r=0.27,0.28,Ps＜0.05).Conclusion:The study shows that blind individuals have lower voice-personality ratings on others than their sighted peers,which might be due to some of their more negative per-sonality characteristics.

Objective To investigate the application value of transumbilical single-port total laparoscopic hysterectomy by conventional instrument without uterine-lifting in the treatment of cervical lesions.Methods We selected 60 cases of total laparoscopic hysterectomy due to cervical high-grade squamous intraepithelial lesion(HSIL)or cervical cancer stage ⅠA1 from December 2021 to June 2023.According to the patients'preference,30 cases of single-port laparoscopy through the umbilicus and 30 cases of multi-port laparoscopy were performed,both using conventional instruments without uterine-lifting.The surgical indicators of the two groups were compared.Results No conversion to open surgery occurred in both groups,and no intraoperative injuries to the urinary system,bowel,or major blood vessels occurred.As compared with the multi-port group,the single-port group had significantly reduced amount of bleeding during surgery[(54.6±20.5)ml vs.(67.5±27.0)ml,P = 0.041],earlier anal exhaust time[(27.6±8.0)h vs.(32.2±9.0)h,P =0.040],and shorter total hospitalization time[(4.4±1.5)d vs.(5.1±1.2)d,P = 0.044].There were no significant differences in uterine weight,surgical time,and postoperative complications between the two group(P>0.05).The healing of the abdominal wall puncture wounds in both groups of patients were satisfied.There were no short-term complications related to the puncture device(such as puncture wound infection and bleeding)or long-term complications(such as umbilical hernia and incisional hernia).Conclusion Transumbilical single-port total laparoscopic hysterectomy without uterine-lifting presents advantages of less intraoperative bleeding,faster postoperative recovery,and almost no scarring,with complications similar to traditional laparoscopic surgery.

Objective To investigate the basic conditions of non-medical radiation institutions and their current status of occupational health management of radiation workers and radiation protection in workplaces in Tianjin City, China, and to clarify the key points of occupational health management and radiation protection efforts. Methods A comprehensive survey was conducted to assess the basic conditions of non-medical radiation institutions and their status of occupational health management for radiation workers across 16 districts in Tianjin in 2023. Then, some non-medical radiation institutions were chosen according to their industrial sections as sentinel institutions to investigate radiation protection in workplaces. Results In 2023, there were a total of 431 non-medical radiation institutions in 16 districts of Tianjin, primarily in the industries of nuclear instrument, industrial radiography, and others. In these institutions, there were a total of 5264 radiation workers, with 93.8%, 93.0%, and 93.7% participating in the training of radiation protection, the occupational health examination, and the personal dose monitoring, respectively. Eighty-six non-medical radiation institutions were chosen as the sentinel institutions for investigation of radiation protection conditions in workplaces. The resulting data met the stipulated limits according to relevant standards. Conclusion The current status of occupational health management and radiation protection in non-medical radiation institutions in Tianjin is satisfactory. However, there is a need for further management enhancements, particularly in key industries such as nuclear instrumentation and industrial radiography.

Objective To explore the current status of posttraumatic growth (PTG) among nurses at psychiatric department and analyze its latent profiles and population characteristics. Methods A total of 357 nurses from psychiatric departments of five tertiary Grade A hospitals were selected as the research subjects using the convenience sampling method. The PTG and professional quality of life were studied using the Posttraumatic Growth Inventory and the Chinese version of the Compassion Fatigue Scale. Results The PTG score of the nurses was (56.6±23.2). The scores of compassion satisfaction, burnout, and secondary traumatic stress among nurses were (32.6±7.2), (26.9±5.9), and (26.0±5.4), respectively. The result of potential profile analysis showed that the nurses could be divided into three latent profiles based on PTG levels: low PTG group (34.4%), moderate PTG group (44.0%), and high PTG group (21.6%). The results of multinomial logistic regression analysis showed that the nurses who slept 7-8 hours per day were at higher risk of being in the high PTG group compared with those who slept more than eight hours per day (P<0.05). Psychiatric nurses who took regular exercise were at higher risk of being in the high PTG group compared with those who took irregular exercise (P<0.05). The nurses who had high job satisfaction scores were at higher risk of being in the high PTG group compared with those who had low job satisfaction scores (P<0.01). The nurses with higher compassion satisfaction scores increased the risk of being in the high PTG group compared with those with lower compassion satisfaction scores (P<0.01). The nurses with higher burnout scores increased the risk of being in the low PTG group compared with those with lower burnout scores (P<0.01). Conclusion The PTG characteristics of the nurses exhibit heterogeneity and can be categorized into three distinct profiles. Sleep duration, regular exercise, job satisfaction, compassion satisfaction, and burnout are influencing factors for the PTG latent profiles of nurses working at psychiatric department.

The integration of regional medical centers and community health service centers is an effective way to improve the professional ability of general practitioners in post-practice training. Its major advantage lies in the establishment of a regional general practitioner ability improvement system integrating assessment, practice and teaching under the unified health administrative department. This article introduces the path of general practitioner post-training developed by Shanghai Tongren Hospital in forms of a regional medical center combined with the community health service center under the "integrated dual-drives" model, which was carried out in Shanghai Changning District; and its preliminary accomplishment is also discussed. It may provide reference for regional medical centers to improve the ability of general practitioners through practice-driven and teaching-driven.

Objective:To analyze the clinical knowledge and training needs of general practitioners from subjective perception and objective assessment, and to analyze their relationship.Methods:A survey was conducted among general practitioners from community health service centers in Shanghai Changning district from September to December 2020. Based on the general practitioner competency indicator system designed by the project team, 17 clinical knowledge competency evaluation indicators were developed through expert consultation, and used for subjective perception and objective assessment of clinical knowledge and learning needs among general practitioners. The influencing factors of objective assessment scores were analyzed, and the relationship between subjective perception and objective assessment scores was analyzed using the four quadrant method.Results:A total of 136 general practitioners participated in the study with the mean age of (39.25±5.90) years, most of whom were attending physician (67.65%, 92/136) and had undergraduate education (88.20%, 122/136). The average daily application frequency score was (1.55±0.21), and the training needs score was (1.65±0.09) for 17 clinical knowledge items; the average objective evaluation score was (74.21±14.0) points. The older the age ( OR=1.25, 95% CI:1.14-1.37), the higher the educational level ( OR=2.11, 95% CI:1.57-2.83), and the longer the working years ( OR=1.16, 95% CI:1.04-1.30) were significantly correlated with the higher objective evaluation scores (all P<0.05). The objective evaluation scores of endocrine diseases such as diabetes, cerebrovascular diseases and respiratory diseases are the highest, and the daily application frequency and learning needs are high (the first quadrant); The objective evaluation scores of common orthopedic diseases, common psychological diseases, and planned immunity indicators were relatively low, but their daily application frequency and learning needs were relatively high (second quadrant). The objective evaluation scores of indicators such as common malignant tumors, common dermatology diseases and health problems, and common ENT diseases were low, and the daily application frequency and learning needs were also low (the third quadrant). The objective evaluation scores of indicators such as hospice and palliative care are relatively high, but their daily application frequency and training needs are relatively low (listed in the fourth quadrant). Conclusions:The clinical knowledge levels of general practitioners are correlated with age, education level, and years of practice. There is a certain overlap between the objective evaluation results of clinical knowledge and the frequency of knowledge usage and training needs of general practitioners, and a targeted training mechanism should be established.

Objective:To construct an evaluation scale for post competence of family doctors based on knowledge-skill-management model.Methods:The evaluation dimensions and indicators for post competency of family doctors were preliminarily developed through literature review, internal group meeting and brainstorming, and in-depth interviews of experts. And 16 experts in the fields of general practice and health management were invited for 2 rounds of Delphi consultation from December 2020 to April 2021. A competency evaluation scale for family doctors based on the dimensions of knowledge, skills and management was finally constructed.Results:The age of the experts was (47.9±7.3) years with a working experience of (24.6±7.8) years. The Cronbach′s α of the questionnaires was 0.891 and the KMO was 0.844. The positive coefficients for 2 rounds of expert consultation were 100%; the familiarity level of experts was 0.86 and authority level was 0.89 in the first round consultation, and those were 0.84 and 0.90 in the second round consultation. After 2 rounds of consultation, the coordination coefficient of expert opinions in the knowledge and skill dimensions was>0.5, and that in the management dimension and overall evaluation system was>0.3. After discussion 2 indicators were deleted in the first round of consultation. The finally constructed family doctor post competency evaluation scale included 3 dimensions, 8 secondary indicators and 61 tertiary indicators. Conclusion:Through the Delphi consultation, we have successfully constructed an evaluation scale for post competence of family doctors based on the three dimensions of knowledge, skills and management.

Objective:To study the level of CT dose to paediatric patients in Tianjin, and to provide basic data for establishing the diagnostic reference levels for paediatric patients from CT examinations in Tianjin.Methods:In 2022, a general survey was carried out of the CT doses to the head, chest, abdomen and pelvis of the scanned paediatric patients in two tertiary pediatric hospitals and seven tertiary general hospitals in Tianjin. The scanned pediatric patients were divided into four age groups in terms of the age of -1, -5, -10 and -15 years, and 20 patients were investigated in each age group in each hospital. The basic information were collected on the scanned patients, CT scanning parameters, volume CT dose index (CTDI vol), dose length product (DLP), and the differences in CTDI vol and DLP on the same site among different age groups and different types of hospitals were analyzed. Results:There were significant differences in CTDI vol and DLP between different age groups at the same site (head, chest, abdominal and pelvic, CTDI vol:χ2=296.51, 193.82, 291.72, P<0.001; DLP: χ2=291.22, 263.63, 344.97, P<0.001). There were significant differences in CTDI vol and DLP among different types of hospitals on the same site (head, chest, abdominal and pelvic, CTDI vol:Z=-13.13, -7.57, -15.27, P<0.001; DLP: Z=-9.07, -6.15, -11.57, P < 0.001). Conclusions:The 75 th percentile values of CTDI vol and DLP for pediatric head, chest, abdomen and pelvis CT scanning in tertiary hospitals in Tianjin are at a good level, and the dose on some examination sites are relatively high. Further optimization of pediatric CT scanning procedures is necessary.

Objective:To evaluate the clinical effect of anterior clinoid process grinding in the treatment of ophthalmic / superior clinoid process aneurysms and sellar tumors.Methods:The clinical data of 16 patients who underwent anterior clinoid process grinding in Sanbo Brain Hospital, Capital Medical University from January 2015 to July 2021 were analyzed retrospectively. There were 1 patient with recurrent craniopharyngioma, 1 patient with recurrent pituitary adenoma, 13 patients with aneurysms, and 1 patient with suprasellar granulosa cell tumor combined with ophthalmic aneurysm of right internal carotid artery. The Modified Rankin Scale (mRS) score was used to evaluate the situation at discharge and in the medium-and-long term.Results:Sixteen patients underwent anterior clinoidprocess grinding. At discharge and the latest follow-up, the mRS scores of the patients were 0-2. A total of 15 aneurysms were treated, and there were no symptoms of visual loss or visual field defect after operation. No cerebrospinal fluid leakage occurred in all patients.Conclusions:The grinding of anterior clinoid process can effectively and fully stretch the optic nerve and internal carotid artery, and can observe the tumor neck at the lower end of pituitary stalk and the ocular segment/superior clinoid process of internal carotid artery under direct vision. It is one of the important auxiliary methods for the treatment of sellar lesions.
