Objective:To investigate the clinicopathological characteristics and prognostic factors of biliary neuroendocrine neoplasms (NENs).Methods:The retrospective cohort study was conducted. The clinicopathological data of 36 patients who underwent surgical treatment for biliary NENs at The First Hospital of Jilin University from January 2013 to December 2023 were collected. There were 22 males and 14 females, aged (59±9)years. Observation indicators: (1) clinicopatholo-gical characteristics of patients; (2) follow-up; (3) prognostic factors analysis of patients. Compari-son of measurement data with normal distribution among multiple groups was conducted using the ANOVA. Comparison of measurement data with skewed distribution among multiple groups was conducted using the Kruskal-Wallis H test. Comparison of count data between groups was conducted using the chi-square test or Fisher exact probability. The Kaplan-Meier method was used to calculate survival rate and plot survival curve, and Log-rank test was used for survival analysis. The Cox risk regression model was used for univariate and multivariate analyses. Results:(1) Clinicopatholo-gical characteristics of patients. None of the 36 patients with biliary NENs had carcinoid syndrome. There were 11 cases with tumor located at gallbladder, 14 cases with tumor located at bile duct, and 11 cases with tumor located at ampulla of Vater. There were significant differences in weight loss and TNM stage among biliary NENs patients with different tumor location ( χ2=9.14, 6.54, P<0.05). Of the 36 patients, there were 12 cases with neuroendocrine tumors, 16 cases with neuroendocrine carcinomas, and 8 cases with mixed neuroendocrine-non-neuroendocrine neoplasms. (2) Follow-up. All 36 patients were followed up for 39(range, 10-93)months. Of the 36 patients, 19 patients experienced tumor recurrence and 16 patients experienced tumor metastasis. There were 18 patients died. The median overall survival time of 36 patients was 30 months, with the 1-, 2-, 3-year overall survival rates of 63.9%, 51.0%, and 35.7%, respectively. The 1-, 2-, 3-year recurrence-free survival rates were 47.5%, 34.1% and 21.3%, respectively. The 1-, 2-, 3-year overall survival rates of 19 patients with tumor recurrence were 55.6%, 55.6% and 27.8%, respectively. The 1-, 2-, 3-year overall survival rates of 17 patients without tumor recurrence were 71.3%, 50.4% and 42.0%, respectively. There was no significant difference in overall survival between patients with and without tumor recurrence ( χ2=0.24, P>0.05). (3) Prognostic factors analysis of patients. Results of multivariate analysis showed that pathological type as neuroendocrine carcinomas and mixed neuroendocrine-non-neuroendocrine neoplasms, non-R 0 margin were independent risk factors influencing overall survival time of patients ( hazard ratio=5.50, 5.33, 14.04, 95% confidence interval as 1.32-23.01, 1.17-24.35, 2.67-73.79, P<0.05). Conclusions:Biliary NENs lack specific clinical manifestations. Poorly differentiated neuroendocrine carcinomas are the most common pathological type. Pathological type as neuroendocrine carcinomas and mixed neuroendocrine-non-neuroendocrine neoplasms, non-R 0 margin are independent risk factors influencing prognosis of patients.

Objective:To study whether the bone age of the left and right limbs in children was consistent when the ossification ratio was measured by ultrasound,and to compare this consistency between ultrasound bone age of left and right limbs,and the bone age that was determined by X-ray. Method:A total of 526 children aged 3 to 18 years,who were treated at the Affiliated Hospital of Guizhou Medical University from October 2022 to November 2023,were retrospectively included. The ossification ratios of the left and right ulna,radius,and femur of these children were measured by using ultrasound to calculate the bone age of ultrasound. Simultaneously,all children underwent X-ray examination on left-hand for bone age within two weeks before and after the ultrasonic examination for bone age. The differences in ossification ratios of the ulna,radius and femur of dual sides in assessing bone age by using ultrasound were compared,and the differences of assessing bone age among left ultrasound,right ultrasound and X-ray were further compared. Results:In the ultrasound test,Ossification rate of the left ulna was 48.0％,Less than 49.5％ on the right side,The difference was statistically significant (W=25425.5,P<0.001),the left femoral ossification rate was 77.0％,Higher than 76.0％ on the right side,The difference was statistically significant (W=57829,P=0.041). The overall ossification rate of the left ulna,radius,and femur was 184.0％,Below 185.0％ on the right side,The difference was statistically significant (W=46314.5,P<0.001). The ultrasound bone age of the left limb was 10.1 years,Below 10.3 years on the right,The difference was statistically significant (W=67958.5,P<0.001). The median X-ray bone age of the included children was 10.2 years between ultrasound bone age and X-ray bone age (P>0.05). Conclusion:There is difference in the bone age between left and right side of limbs in assessing bone age by using ultrasound to detect ossification ratio. Therefore,the left and right sides should be assessed by using ultrasound to assess bone age.

A scientific and efficient comprehensive operation system for the transformation of clinical research achievements is an important guarantee to fully release the capability of public hospitals of the achievement transformation. A public hospital, focusing on the bottleneck problems faced in the process of transforming scientific and technological achievements, began to explore the construction of a comprehensive operation system for the transformation of clinical research achievements and implemented it throughout the hospital from October 2023. By improving the organizational structure and setting up full-time management positions; formulating supporting policies and perfecting the incentive mechanism; drawing a systematic portrait and creating a standard pathway; expanding the transformation platform and promoting coordinated development; innovating management services and strengthening digital empowerment; and highlighting publicity and education to enhance the capability of transformation, the hospital has effectively promoted the transformation of clinical research achievements. This practice can provide a reference for other hospitals to improve the management of clinical research achievements transformation and promote high-quality hospital development.

Chronic temporomandibular joint disorders(TMD)patients usually suffer from persistent pain and physical, behavioral, psychological, and social symptoms. Effective control and treatment method are needed to restore their jaw function and manage pain. With the concept of biosupplementation proposed, plasma matrix products have gradually become popular in articular disease treatment and have become one of the core method of regenerative therapy. This paper mainly introduces the application characteristics and action mechanism of injectable platelet-rich plasma fibrin. It analyzes several research reports on the effect of injectable platelet-rich fibrin on pain control, mouth opening improvement and joint morphology restoration in TMD patients. It proposes that differences exist in current clinical trials such as different centrifugation schemes for plasma matrix products, injection times, and disease classification selection, providing a reference for the research and application of injectable platelet-rich fibrin in the treatment of TMD.
