Objective:
To explore the prevalence of bone defect and alveolar bone thickness changes in the mandibular incisors of untreated adults and post-orthodontic treatment adults, with the aim of providing strategies for preventing and managing alveolar bone defects during orthodontic treatment.
Methods:
This study was reviewed and approved by the Medical Ethics Committee. Clinical records, panoramic radiographs, cephalometric radiographs, and cone beam computed tomography (CBCT) images and informed consent were obtained for 150 untreated adults and 150 post-orthodontic adults. The untreated adults and post-orthodontic adults were respectively divided into three subgroups: skeletal ClassⅠ, Class Ⅱ and Class Ⅲ, with 50 cases per subgroup. Meanwhile, 60 cases with completeness of pre- and post-orthodontic data were enrolled from 150 post-orthodontic adults, including 20 cases each of skeletal ClassⅠ, Class Ⅱ, and Class Ⅲ. Cephalometric radiographs were imported into Dolphin software to measure skeletal parameters. CBCT images were imported into Mimics software to assess alveolar bone defects and to measure alveolar bone thickness of mandibular incisors among three groups: 150 untreated adult groups, 150 post-orthodontic groups and the pre- and post-treatment status of 60 patients selected from the latter group.
Results:
Untreated adult patients: the prevalence of labial dehiscence and fenestration in the mandibular incisors was higher than that on the lingual side among skeletal ClassⅠ, Ⅱ, and Ⅲ malocclusion patients, and there was a statistically significant difference in the alveolar bone thickness of the mandibular incisors among the three classes. Post-orthodontic treatment adults: for skeletal ClassⅠ and Ⅱ patients, the prevalence of lingual bone dehiscence in the mandibular incisors was significantly higher in the extraction groups than in the non-extraction groups; correspondingly, the lingual alveolar bone was also thinner in the extraction groups; Class Ⅱ non-extraction patients showed a higher prevalence of labial bone fenestration but a lower prevalence of lingual bone fenestration in mandibular incisors compared to Class Ⅱ extraction patients; the orthodontic-orthognathic combined treatment group showed significantly higher prevalence of labial/lingual bone dehiscence and thinner alveolar bone at multiple sites in the mandibular incisors compared to the camouflage group in skeletal Class Ⅲ patients. Comparison of mandibular incisor bone defects and thickness before and after orthodontic treatment in adult patients: in skeletal ClassⅠ and Ⅱ patients treated with premolar extraction and Class Ⅲ patients treated with orthodontic-orthognathic combined treatment, the lingual alveolar bone of mandibular incisors exhibited significant resorption and thinned after treatment, and this was accompanied by an increased prevalence of dehiscence; in non-extraction patients, ClassⅠ non-extraction patients showed thinning of the crestal-labial bone and apical-lingual bone, Class Ⅱ patients showed thinning of the crestal-labial bone and middle-labial bone of the mandibular incisors, along with an increased prevalence of dehiscence
Conclusion
In malocclusion adults, alveolar bone defects were already present in the mandibular incisors before orthodontic treatment. The alveolar bone defects and thickness in mandibular incisors among post-orthodontic adults were influenced by the treatment plan and Class of skeletal malocclusion.

In recent years, the rising prevalence of obesity and its associated metabolic syndromes has emerged as a critical global public health concern. Sustained weight loss exceeding 10% of total body weight has been shown to ameliorate obesity-related comorbidities, including type 2 diabetes mellitus, hypertension, and hepatic steatosis. Recently, the potential of brown adipose tissue (BAT) to improve metabolism has garnered significant attention. However, evidence regarding weight loss therapies that promote BAT activation remains limited in preclinical models and is even scarcer in clinical studies, partly due to the paucity of appropriate BAT assessment techniques. This review aims to explore the potential impact of various weight loss therapies on BAT, with the goal of providing novel insights and strategies for the treatment of obesity.

Objective To investigate the cross-sectional associations between different fatty liver classifications and cardiac structure and function in people undergo health examination. Methods A total of 6 545 adults who underwent health examinations at the Health Management Center of Zhongshan Hospital, Fudan University between January 1 and December 31, 2017, were retrospectively included. Demographic characteristics and laboratory data were collected. The hepatic steatosis was graded by ultrasonography. And patients with fatty liver were further stratified according to alanine aminotransferase (ALT) or aspartate aminotransferase (AST) levels, as well as the degree of liver fibrosis. Cardiac morphology and function were assessed by transthoracic echocardiography, and left ventricular geometric patterns were classified accordingly. Multivariate logistic regression analysis was performed to evaluate the associations between fatty liver classifications and cardiac abnormalities. Results There were 2 795 patients (42.7%) with fatty liver, of whom 832 (29.8%) had significant cardiac structural alterations and 1 500 (53.7%) had diastolic dysfunction. Severe fatty liver was risk factor for concentric remodeling and increased relative wall thickness (RWT), with odds ratios (ORs) of 1.27 (P=0.012) and 1.27 (P=0.009), respectively. Fatty liver accompanied by elevated ALT or AST was risk factor for concentric remodeling (OR=1.45,1.56; P=0.001, 0.001), increased RWT (OR=1.48,1.57; P<0.001, <0.001), and diastolic dysfunction (OR=1.27, 1.32; P=0.035, 0.040), respectively. Fatty liver with liver fibrosis was risk factor for concentric remodeling (OR=1.83, P=0.046) and diastolic dysfunction (OR=2.64, P=0.034). Conclusions Advanced fatty liver, including severe hepatic steatosis, accompanied by elevated liver enzymes or liver fibrosis, could increase risks of cardiac remodeling and diastolic dysfunction, while systolic function is preserved. For patients with fatty liver, it is recommended to undergo regular ultrasonography examination.

Objective To explore the efficacy and safety of neoadjuvant immunotherapy combined with chemotherapy in patients with locally advanced resectable non-small cell lung cancer (NSCLC). Methods The clinical data of patients with stage ⅡA-ⅢB NSCLC who underwent surgical treatment after receiving neoadjuvant immunotherapy combined with chemotherapy or chemotherapy alone at the First People’s Hospital of Jining between April 2021 and January 2024 were retrospectively analyzed. According to the preoperative neoadjuvant regimens, the patients were divided into a combined group and a chemotherapy group, and the clinical data of the two groups were compared. Results A total of 66 patients were included, including 61 males and 5 females. There were 53 patients in the combined group with a mean age of (63.40±6.80) years, and 13 patients in the chemotherapy group with a mean age of (58.62±8.30) years. There was a statistical difference in age between the two groups (P<0.001), while no statistical difference was observed in other baseline data (P>0.05). The major pathological response rates in the combined group and the chemotherapy group were 54.7% and 23.1%, respectively (P=0.041), and the pathological complete response rates were 39.6% and 0.0%, respectively (P=0.006). The operative time in the combined group was shorter (P=0.039). There were no statistical differences between the two groups in intraoperative blood loss, duration of postoperative tube carrying, incidence of postoperative complications, overall survival, or event-free survival (P>0.05). Conclusion Surgical treatment following neoadjuvant immunotherapy combined with chemotherapy is safe and feasible, and its long-term efficacy requires further follow-up for confirmation.

Objective To observe the efficacy and safety of neoadjuvant sintilimab combined with chemotherapy in the treatment of patients with locally advanced resectable esophageal squamous cell carcinoma (ESCC). Methods Clinical data were collected from patients with locally advanced resectable ESCC who received neoadjuvant immunotherapy combined with chemotherapy followed by surgical treatment at the Department of Thoracic Surgery of Jining No.1 People's Hospital from April 2020 to April 2022. The endpoints included major pathological response (MPR), pathological complete response (pCR), R0 resection rate, safety, and postoperative survival. Results A total of 43 patients with ESCC who received at least one cycle of neoadjuvant immunotherapy before surgery were included. Among them, there were 31 males and 12 females with a median age of 65 years (interquartile range: 58-69). All patients successfully completed the surgery without any surgical delays. The pCR rate was 14.0% (6/43), the MPR rate was 58.1% (25/43), and the R0 resection rate was 97.7% (42/43). Patients exhibited reliable safety during neoadjuvant therapy and postoperatively. The 2-year overall survival and disease-free survival rates were 90.7% and 81.4%, respectively. Kaplan-Meier survival analysis and log-rank test revealed lower recurrence rates and better survival in the MPR patients compared to the non-MPR patients. Conclusion The combination of neoadjuvant sintilimab and chemotherapy in the treatment of patients with locally advanced resectable ESCC has demonstrated significant clinical efficacy, while also being safe and reliable.

Approximately 10% of the global adult population has diabetes, with accumulating evidence linking suboptimal vitamin D levels to an increased risk of type 2 diabetes and its complications. Current clinical studies suggest that vitamin D supplementation may enhance insulin sensitivity and improve glycemic control, prompting significant interest in its potential as a therapeutic intervention. However, further high-quality, large-scale randomized controlled trials are required to validate its efficacy in glucose metabolism regulation and clarify the underlying molecular mechanisms. These investigations will provide critical evidence to inform precision medicine approaches for diabetes prevention and management.

Esophageal cancer is one of the malignant tumors that poses a threat to human health, with both high incidence and malignancy. Currently, surgery following neoadjuvant chemoradiotherapy is the standard treatment for locally advanced esophageal cancer; however, the long-term prognosis remains unsatisfactory. In recent years, inhibitors of programmed death protein-1 (PD-1) and its ligand (programmed death ligand-1, PD-L1) have achieved breakthrough progress in other solid tumors, and research on esophageal cancer is gradually being conducted. With the demonstration of good efficacy of PD-1/PD-L1 inhibitors in the first-line and second-line treatment of advanced unresectable esophageal cancer, their incorporation into neoadjuvant treatment regimens has become a hot topic. Therefore, this article reviews the mechanism of action of PD-1/PD-L1 inhibitors and their application in the neoadjuvant treatment of esophageal cancer.

Pre-admission is a critical initiative to optimize medical service processes and alleviate the challenge of "difficult access to healthcare. "However, there is currently a lack of standardized protocols for pre-admission procedures. This study aims to systematically analyze key nodes and risk factors in pre-admission process design and propose optimization strategies, providing a foundation for policy formulation and hospital practices. By constructing a "forward-reverse" dual-process model of pre-admission and identifying risk points based on stakeholder theory (patients, hospitals, healthcare administration, and insurance), the study reveals that while pre-admission can reduce the average length of stay, improve bed turnover rates, and enhance patient satisfaction, it also presents risks such as cross-period financial settlement, challenges in insurance policy adaptability, demands for information system integration, and the need for defining medical safety boundaries. To optimize the pre-admission process and mitigate these risks, this study explores framework improvements in areas including eligibility criteria, mode selection, cost settlement, transition between pre-admission and inpatient status, and cancellation of pre-admission, offering practical guidance for public hospitals. The authors argue that pre-admission requires tripartite collaboration among hospitals, insurers, and healthcare administrations: hospitals should establish top-level design, continuously refine processes, and implement dynamic risk assessment mechanisms; insurance providers should support cross-period settlement policies; and healthcare administrations should issue guiding policies or standardized protocols. Through multi-department coordination and collaborative efforts, the optimization and innovation of pre-admission processes can be advanced, ultimately delivering more efficient and convenient healthcare experiences for patients.

OBJECTIVE To study the effects of milk processing method on the content of esculentoside A and hepatotoxicity in Mongolian medicine Phytolacca acinosa. METHODS High performance liquid chromatography-evaporative light-scattering detection was used to determine the content of esculentoside A in raw P. acinosa, milk-soaked P. acinosa and milk-boiled P. acinosa. The rats were randomly divided into normal group, raw P. acinosa group, milk-soaked P. acinosa group and milk-boiled P. acinosa group, with 10 rats in each group. Except for the normal group, the rats in the remaining groups were administered corresponding medicinal solutions at a dose of 0.8 g/kg once daily for 15 consecutive days. After the last administration, the levels of biochemical markers [alanine transaminase (ALT), aspartate transaminase (AST)] and inflammatory factors [interleukin-2 (IL- 2), IL-6, tumor necrosis factor- α (TNF- α)] in plasma of rats, as well as the levels of malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in liver tissue, were determined. The pathological changes of liver tissue in rats were observed. RESULTS The contents of esculentoside A in raw P. acinosa, milk-soaked P. acinosa and milk-boiled P. acinosa were 6.46-6.59, 4.79-4.89, 5.04-5.14 mg/g, respectively. Compared with the normal group, the plasma levels of ALT, AST, IL-2 and TNF-α in rats were increased significantly in the raw P. acinosa group (P<0.05), while the level of SOD in liver tissue was decreased significantly (P<0.05); scattered punctate necrotic foci were observed within the hepatic lobules, and hepatocytes exhibited slight vacuolar degeneration. Compared with the raw P. acinosa group, the levels of ALT and AST in plasma of rats and the level of MDA in liver tissue were all decreased significantly in the milk-soaked P. acinosa group and the milk-boiled P. acinosa group (P<0.05), while the level of SOD in liver tissue was increased significantly (P<0.05). The plasma level of TNF-α in the rats of the milk-soaked P. acinosa group and the plasma levels of IL-2 and IL-6 in the rats of the milk-boiled P. acinosa group were all decreased significantly (P<0.05); additionally, the degree of liver injury was markedly alleviated in both groups. CONCLUSIONS The content of esculentoside A and hepatotoxicity both decrease after processing Mongolian medicine P. acinosa using the milk processing method.
