BACKGROUND:With the development of oral implantology,implant restoration has gradually become the first choice of restoration after missing teeth,and bone augmentation procedures have led to the expansion of implant indications and the improvement of the success rate of implant restoration.However,the long-term stability of bone height,width and volume after bone augmentation surgery has been one of the clinical difficulties for oral implantologists.OBJECTIVE:To measure and analyze the bone width,height,and volume of different sites in the bone augmentation area at different time points using cone-beam CT and an automatic image alignment program.METHODS:Seventeen patients with severe bone defects in the upper anterior region who underwent Onlay bone block grafting in the external oblique region were recruited from the Department of Stomatology,Zhejiang Tongde Hospital.There were 10 males and 7 females,with a mean age of(45.88±12.47)years.The cone-beam CT scans of the patients' Onlay bone grafts were taken at five time points:preoperatively,immediately postoperatively,6 months postoperatively,immediately post implantation,and 6 months post implantation,and then were statistically analyzed for alveolar bone volume,width,and height in the bone augmentation area,as well as for the difference in the alveolar bone volume of the bone incremental area between patients of different sexes and age.RESULTS AND CONCLUSION:(1)The alveolar bone volume in the bone augmentation area was higher immediately and 6 months after bone grafting than before bone grafting(P＜0.05)as well as was higher immediately after bone grafting than 6 months after bone grafting(P＜0.05).The alveolar bone height in the bone augmentation area was higher immediately and 6 months after bone grafting than before bone grafting(P＜0.05).The horizontal width of the alveolar bone at various sites in the bone augmentation area immediately and 6 months after bone grafting was higher than that before bone grafting(P＜0.05).(2)There was no significant difference in the volume of bone graft resorption at various sites in the bone augmentation area between males and females immediately and 6 months after bone grafting(P＞0.05).Pearson correlation analysis showed a positive correlation between age and the change in bone augmentation area volume immediately and 6 months after bone grafting,but the difference was not statistically significant(P＞0.05).(3)Twenty-five dental implants with completed implant restorations functioned normally,and the survival rate of the implants was 100％.To conclude,Onlay bone graft implant restoration in the upper anterior region can significantly improve insufficient bone with favorable outcomes.However,there is some amount of bone resorption in the bone augmentation area at 6 months after Onlay bone grafting and it is necessary to open up the second surgical area.Clinicians should consider different bone augmentation procedures in accordance with the specific circumstances.

Diabetes mellitus, characterized by glucose metabolism disorders and marked by insulin deficiency or insulin resistance, has seen a continuous rise in prevalence. In recent years, islet transplantation has matured as a therapeutic approach for diabetes, becoming an important method for glycemic control and the reduction of diabetes-related complications. Donor selection directly influences transplant outcomes, and various research institutions worldwide have proposed multiple scoring systems to optimize donor assessment, such as the University of Alberta scoring system and the North American Islet Donor Score. This article explores the impact of key factors such as donor age, body mass index and ischemia time on islet transplantation. Combining practical experience in pancreatic donor selection from Shanghai Changzheng Hospital, it proposes screening criteria for pancreatic donors suitable for China, aiming to provide new evidence for improving the success rate of islet transplantation.

Background: and Purpose In patients with large vessel occlusion (LVO), intravenous thrombolysis (IVT) frequently alters thrombus location; however, the clinical impact of this phenomenon remains unclear. We aimed to compare post-IVT thrombus dynamics between tenecteplase and alteplase and to evaluate the association between thrombus dynamics and 3-month outcomes. Methods: This retrospective study analyzed prospectively collected, multicenter data from consecutive patients with LVO who underwent bridging therapy between January 2022 and December 2024. Thrombus dynamics were classified as resolution, migration, or stability. Analyses incorporated propensity score matching with weighting to balance baseline characteristics. Results: Of the 806 initially included patients, 746 were included after matching (373 treated with tenecteplase and 373 treated with alteplase). The incidence of thrombus migration was significantly higher in the tenecteplase group than in the alteplase group (19.3% vs. 11.3%; odds ratio [OR]: 1.92; 95% confidence interval [CI] 1.27–2.91). The advantage of tenecteplase over alteplase was restricted to patients with an IVT-to-puncture time of <60 minutes (18.6% vs. 6.2%; p=0.001) and was no longer significant when the interval ≥60 minutes (19.7% vs. 15.0%; p=0.204; pinteraction=0.043). Additionally, thrombus migration was associated with a better functional outcome (OR: 1.62; 95% CI 1.04–2.53). Finally, tenecteplase was associated with improved functional independence compared with alteplase (OR: 1.43; 95% CI 1.04–1.95). Conclusions Tenecteplase demonstrated superior efficacy in inducing thrombus migration compared with alteplase, particularly within 60 minutes of IVT administration. Thrombus migration independently predicted improved functional independence. These findings support the preferential use of tenecteplase for bridging therapy in patients with LVO.

Objective: To investigate the trends in incidence and mortality of lung cancer in Huangpu District, Shanghai Municipality from 2002 to 2019, so as to provide the evidence for formulating lung cancer prevention and control measures. Methods: Data of lung cancer incidence and mortality among residents in Huangpu District from 2002 to 2019 were collected through the Shanghai Cancer Registration and Reporting Management System. The crude incidence and mortality of lung cancer was calculated, and standardized by the data from the Chinese Fifth National Population Census in 2000 (Chinese-standardized rate) and the Segi's world standard population in 1960 (world-standardized rate). The trends in incidence and mortality of lung cancer among residents by age and gender were evaluated using annual percent change (APC). Results: A total of 12 965 cases of lung cancer were reported in Huangpu District from 2002 to 2019, and the crude incidence rate was 80.66/105, the Chinese-standardized incidence rate was 34.54/105, and the world-standardized incidence rate was 31.30/105, all showing upward trends (APC=4.588%, 2.933% and 3.247%, all P<0.05). A total of 10 102 deaths of lung cancer were reported, and the crude mortality rate was 62.30/105, showing an upward trend (APC=0.959%, P<0.05); the Chinese-standardized mortality was 25.93/105, and the world-standardized mortality was 22.05/105, both showing downward trends (APC=-1.282% and -1.263%, both P<0.05). The crude incidence and mortality rates of lung cancer in males were higher than those in females (101.39/105 vs. 60.52/105, 85.45/105 vs. 39.87/105, both P<0.05). The crude incidence and mortality rates of lung cancer showed upward trends with age (both P<0.05), reaching their peaks in the age groups of 80-<85 years (341.37/105) and 85 years or above (355.97/105), respectively. Conclusions The incidence of lung cancer showed an upward trend, while the mortality showed a downward trend in Huangpu District from 2002 to 2019. Elderly men were the high-risk group for lung cancer incidence and mortality.

BACKGROUND:Alveolar bone defects can jeopardize patients'oral and jaw function and physical and mental health,and reduce their quality of life.Melatonin can be used for the prevention and treatment of bone defect diseases due to its properties of promoting bone regeneration,and also has important applications in osseointegration and peri-implant inflammation related to oral implants.OBJECTIVE:To explore the mechanism by which melatonin promotes bone regeneration,the potential application of melatonin in the field of oral implantation,and to provide new ideas for the utilization of melatonin's osteogenic properties in oral implantation.METHODS:With"melatonin,bone defect,osteoblast,osteoclast,reactive oxygen species,periodontitis,osseointegration,peri-implantitis"as Chinese and English search terms,the relevant literature was searched in CNKI and PubMed databases.The timeframe of the search was from January 2019 to August 2024,while a few classical early documents were included.Screening was carried out by reading the titles and abstracts,and 91 papers were finally included for review.RESULTS AND CONCLUSION:(1)Melatonin promotes bone regeneration by promoting the proliferation and differentiation of osteoblasts,chondrocytes and vascular endothelial cells,inhibiting bone resorption and limiting oxidative stress.(2)Melatonin,as a promoter of bone formation,plays a role in promoting osseointegration and preventing peri-implantitis in oral implants.(3)More research is needed in the future to completely reveal the osteogenic mechanisms of melatonin and to make guidelines for optimal administration conditions and safety of melatonin in osseointegration and peri-implantitis.

Objective To investigate the risk factors of infection of Pseudomonas aeruginosa combined with Elizabethkingia anophelis in patients with cerebral hemorrhage and the antimicrobial treatment plan.Methods Clinical pharmacists participated in the treatment of pulmonary infection caused by Pseudomonas aeruginosa combined with Elizabethkingia anophelis in a patient with cerebral hemorrhage.The risk factors of Elizabethkingia anophelis infection and antimicrobial treatment plan were analyzed by referring to literature and combining the patient's condition,medical history,drug use history and related examination results.Results Based on the infection site,the characteristics of mixed bacterial infection,and the metabolic/pharmacodynamic characteristics of antimicrobial agents,clinical pharmacists made drug recommendations for clinicians in the adjustment of anti-infection protocols,and patients'systemic infections were effectively controlled.Conclusion Elizabethkingia anophelis is a conditional pathogen with low virulence and is not easy to infect healthy people.When the patient's immunity is low,it is easy to transform into pathogenic bacteria,which should be paid attention to.

Primary adrenal lymphoma (PAL) is a rare extranodular lymphoma. It is subject to misdiagnosis due to atypical clinical and imaging features. Histopathology is required to establish the diagnosis. Patients often present to the Endocrinology Department upon revelation of adrenal incidentalomas by imaging. PAL is often accompanied by invasion of other tissues and organs, with a high mortality rate and a poor prognosis. In this paper, the clinical features of a patient with primary adrenal lymphoma and intracranial invasion were summarized, and the pathogenesis, clinical manifestations, diagnosis and treatment of this disease were reviewed.

Objective:To compare the clinical efficacy and safety of intra-articular platelet rich plasma combined with hyaluronic acid and platelet rich plasma alone in the treatment of knee osteoarthritis.Methods:The relevant literatures published between January 2010 and December 2021 on the randomized control study of intra-articular injection of platelet rich plasma and hyaluronic acid and injection of platelet rich plasma only in the treatment of knee osteoarthritis were searched. The bias risk of all the literatures included in the study was evaluated by Revman 5.3 software, and the data were processed and analyzed by Stata 16.0 software. The standardized mean difference ( SMD) was calculated for the difference of efficacy indexes, and the difference was compared by t- test. The odds ratio ( OR) was calculated for the difference of safety in-dex, and the difference was compared by t- test. Results:①A total of 7 relevant research literatures were in-cluded, all of which were in English. ②A total of 675 patients were included in the study, of which 330 patients were treated with intra-articular injection of platelet rich plasma and hyaluronic acid, and 345 patients were treated with intra-articular injection of platelet rich plasma only. ③The VAS scores of patients with platelet rich plasma and hyaluronic acid injection combined with injection and platelet rich plasma injection alone were compared. After 1 and 3 months of injection, the VAS scores of patients with platelet rich plasma combined with hyaluronic acid injection were compared with those of patients with platelet rich plasma injection only. There was no significant difference[ SMD(95% CI)=-0.02(-0.30, 0.27), t=-0.12, P=0.902; SMD(95% CI)=-0.40(-0.80, 0.00), t=-1.97, P=0.051]. After 6 months of injection, the VAS scores of patients with combined injection of platelet rich plasma and hyaluronic acid were significantly lower than those of patients with injection of platelet rich plasma only, and the difference was statistically significant [ SMD(95% CI)=-0.33 (-0.55, -0.11), t=-2.98, P=0.012]. ④The WOMAC scores of patients with combined injection of platelet rich plasma, hyaluronic acid and platelet rich plasma only were compared. After 12 months of treatment, the WOMAC scores of patients with combined injection of platelet rich plasma and hyaluronic acid were significantly higher than those of patients with PRP only, and the difference was statistically significant [ SMD(95% CI)=-0.30(-0.58, -0.03), t=-2.14, P=0.033]. ⑤The incidence of adverse events of platelet rich plasma combined with hyaluronic acid was lower than that of platelet rich plasma only [ OR(95% CI)=0.55(0.33, 0.93), P=0.021]. Conclusion:Compared with intra-articular injection of platelet rich plasma only, the short-term clinical efficacy of combined injection of platelet rich plasma and hyaluronic acid is equivalent to that of injection of platelet rich plasma only, but the long-term clinical efficacy is significantly better, and the safety of combined injection of platelet rich plasma and hyaluronic acid is significantly better.
