Objective To evaluate the morphological differences of the glenoid fossa in adult patients with Angle's Class Ⅱ maloc-clusions.Methods The cone-beam computed tomography(CBCT)images of bilateral temporomandibular joints in 82 patients with av-erage mandibular angle were selected.The patients were divided into 4groups including skeletal class Ⅰ with Angle's Class Ⅱ division 1,skeletal class Ⅰ with Angle's Class Ⅱ division 2,skeletal class Ⅱ with Angle's Class Ⅱ division 1 and skeletal class Ⅱ with Angle's Class Ⅱ division 2.Angular and linear measurements of the glenoid fossa were evaluated and the differences among the groups were statis-tically analyzed.Results The functional articular eminence inclination(AEI-BFL)showed statistical differences between skeletal classⅠ and skeletal class Ⅱ groups with the same occlusal relationship and between the two Angle's Class Ⅱ groups with the same sagittal skele-tal relationships(P＜0.05),while the anatomical articular eminence inclination(AEI-TRL)showed no statistical differences among groups(P＞0.05).The width of the glenoid fossa(GFW),the depth of the glenoid fossa(GFD),the ratio of the GFW to the GFD(GFW/GFD)showed no statistical differences among different groups(P＞0.05).Conclusion The morphology of the glenoid fossa re-vealed differences in the Angle's Class Ⅱ with skeletal class Ⅰ and class Ⅱ patients.

Objective:To evaluate the efficacy and safety of Neuroform Atlas stent-assisted coil embolization in patients with middle cerebral artery bifurcation aneurysms.Methods:A retrospective analysis was performed; the clinical data of 46 patients with middle cerebral artery bifurcation aneurysms accepted Neuroform Atlas stent-assisted coil embolization in First Affiliated Hospital of Zhengzhou University, Beijing Tiantan Hospital Affiliated to Capital Medical University, First Affiliated Hospital of Harbin Medical University, Zhujiang Hospital of Southern Medical University and First Affiliated Hospital of Chongqing Medical University from January 2022 to March 2024 were collected. There were 28 ruptured aneurysms (60.87%) and 18 unruptured aneurysms (39.13%). Follow-up was performed for more than 3 months; Raymond-Roy grading was used to evaluate the aneurysm embolization immediately after embolization and during follow-up; perioperative hemorrhagic or ischemic complications were recorded; modified Rankin Scale (mRS) was used to evaluate the prognosis of the patients at discharge and during follow-up (mRS score≤2: good prognosis, and mRS score>2: poor prognosis).Results:Coil embolization was successful in all 46 patients. DSA immediately after embolization showed that 41 patients (89.13%) had completely occluded aneurysms (Raymond-Roy grading I), 2 patients (4.35%) had residual aneurysm neck (Raymond-Roy grading Ⅱ) and 3 patients (6.52%) had partially occluded aneurysms (Raymond-Roy grading Ⅲ). Perioperative complications occurred in 5 patients, including 2 with postoperative cerebral infarction, 1 with hydrocephalus, 1 with postoperative pneumonia leading to respiratory failure, and 1 with stent thrombosis during embolization. Both at discharge and 3 months after embolization, 43 patients (93.48%) had good prognosis and 3 patients (6.52%) had poor prognosis. No obvious ischemic complications (such as stent restenosis) or hemorrhagic complications (such as re-rupture of the aneurysms) were found in all patients. Thirty patients (65.22%) had imaging follow-up for 6-12 months: 26 (86.67%) had Raymond-Roy grading I, 3 (10.00%) had Raymond-Roy grading II, and 1 (3.33%) had Raymond-Roy grading III.Conclusion:Neuroform Atlas stent-assisted coil embolization has good short-term efficacy and high safety in middle cerebral artery bifurcation aneurysms, but long-term follow-up observation is still needed to verify its efficacy.

Objective:To analyze the research trends and hotspots of anti-Müllerian hormones (AMH) from 2006 to 2020, and to provide reference for future research in related fields.Methods:Based on the PubMed database, the literatures related to AMH collected from January 1st, 2006 to December 31st, 2020 were retrieved, and the bibliometric method was used to analyze the relationship between each stage and AMH with every 5 years as the time node. The publication trends, high-frequency main MeSH/subheadings co-occurrence and research hotspots related to AMH were discussed and forecasted.Results:A total of 4 276 related literatures were retrieved in this paper, and the total number of published papers showed an increasing trend. Relevant research hotspots were gradually increasing. The core research from 2005 to 2010 was the biomarker effect of AMH; from 2011 to 2015 and 2016 to 2020, the core research hotspots were all AMH and polycystic ovary syndrome.Conclusion:While the research hotspots related to AMH have been continuously expanded and enriched, there are also certain changes and alternations, and some emerging hotspots still have the value and significance of further research. AMH type Ⅱ receptor and fertility preservation may become an emerging hotspot in this field in the future.

Objective:To investigate the cognition and demands of parents of premature infants on family integrated care (FICare) and to provide reference for formulating appropriate FICare programs.Methods:Using the convenient sampling method, a total of 160 parents of premature infants who were followed up in Neonatal Integrated Clinic of Children 's Hospital of Chongqing Medical University from March to July 2021 were selected as the research objects. The parents of premature infants were surveyed using a self-designed Questionnaire on the Cognitive Needs of Parents of Premature Infants on FICare. A total of 160 questionnaires were distributed and 140 valid questionnaires were recovered, with the effective recovery rate of 87.5%. Results:Among 140 parents of premature infants, 135 parents thought FICare was beneficial. 71.9% (97/135) parents chose to participate in 1 to 4 hours of care every day, but 31.1% (42/135) parents lacked confidence in care. Among the FICare providers selected by the parents, 94.1% (127/135) were neonatologists, 88.9% (120/135) were neonatal nurses, 62.2% (84/135) were breast-feeding counselors and 62.2% (84/135) were dietitians. 66.7% (90/135) parents and 58.5% (79/135) parents chose simulation teaching and online course as the ideal training mode. Discharge guidance was the service that parents urgently needed, with a score of 74.5%.Conclusions:Parents of premature infants have multi-level and multi-dimensional demands for FICare, so it is necessary to develop multi-level and all-round FICare services based on parents ' demands in the future to improve the outcomes of families of premature infants.

Rotator cuff tears are one of the three most prevalent musculoskeletal disorders, with the supraspinatus tendon as the most common lesion site. It may lead to chronic shoulder pain, weakness and limited joint motion, and eventually to secondary degeneration of the shoulder. As traditional biomechanical experiments are limited by measurement techniques and ethical issues, it is almost impossible to clarify the stress distributions at the rotator cuff under physiological and pathological conditions. Recently, advances in computer science, software development and image processing have rapidly improved finite element models of shoulder joint which promote the researches into pathogenesis of rotator cuff tears and their surgical techniques, making finite element analysis an indispensable means in the biomechanic research of rotator cuff. This paper reviews the recent literature available in China and abroad to expound on the element models of shoulder joint applied in the researches into pathogenesis and surgery of rotator cuff tear.

Objective To evaluate the clinical efficacy of antibiotic -impregnated shunt catheters in hydrocephalus shunt. Methods A retrospective analysis of clinical data from patients with hydrocephalus shunt surgery in our hospital during the period from May 2011 to August 2016. Based on the types of catheters, patients were divided into common conduit (not AISCs group) and antibiotics infiltrating pipe groups (AISCs group). All patients were followed up for 6 months after shunt surgery. The diversion and infection was recorded. Results The data of 193 patients with hydrocephalus shunt were analyzed, including 124 cases of non-AISCs group and 69 cases of AISCs group. Compared with non-AISCs group,the incidence of postoperative infection of AISCs was significantly decreased(P<0.05). There was no significant difference in the incidence of shunt and reoperation between the two groups (P>0.05). In addition, there was no significant difference in the rupture, displacement and exposure of the two groups (P>0.05).Conclusion ASICs can effectively reduce the incidence of hydrocephalus shunt infection.
