Objective To assess the situation and influencing factors of occupational burnout among the staff at the Center for Disease Control and Prevention (CDC) in Sichuan Province. Methods A total of 1 038 CDC staff members in Sichuan Province were selected as the study subjects using the stratified random sampling method. Occupational burnout of the staff was assessed using the Maslach Burnout Inventory General Survey via an online questionnaire. Results The detection rate of occupational burnout was 42.3% (439/1 038). Binary logistic regression analysis result showed that, after controlling for confounding factors such as education level and alcohol consumption, CDC staffs aged at 20-<31, 31-<41, and 41-<51 years were at higher risk of occupational burnout compared with those ≥51 years (all P<0.05). CDC staffs with 5-<10 or ≥10 years of service had higher occupational burnout risk compared with those with <5 years (both P<0.05). CDC staffs with poor or fair health status, irregular diet, and poor sleep quality had higher risk of occupational burnout compared with those healthy, have regular diet, and good sleep quality (all P<0.05). The risk of occupational burnout increased with higher overtime frequency (all P<0.05). Conclusion Occupational burnout among CDC staffs in Sichuan Province is relatively high. Age, years of service, health status, diet, sleep quality, and overtime frequency are key influencing factors.

Vascular damage plays a significant role in the onset and progression of Alzheimer's disease (AD). However, the precise molecular mechanisms underlying the induction of neuronal injury by vascular damage remain unclear. The present study aimed to examine the impact of fibrinogen (Fg) on tau pathology. The results showed that Fg deposits in the brains of tau P301S transgenic mice interact with tau, enhancing the cytotoxicity of pathological tau aggregates and promoting tau phosphorylation and aggregation. Notably, Fg-modified tau fibrils caused enhanced neuronal apoptosis and synaptic damage compared to unmodified fibrils. Furthermore, intrahippocampal injection of Fg-modified tau fibrils worsened the tau pathology, neuroinflammation, synaptic damage, neuronal apoptosis, and cognitive dysfunction in tau P301S mice compared to controls. The present study provides compelling evidence linking Fg and tau, thereby connecting cerebrovascular damage to tau pathology in AD. Consequently, inhibiting Fg-mediated tau pathology could potentially impede the progression of AD.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective: To investigate the trend in disease burden of diabetes mellitus among population aged 15 to 39 years in China from 1990 to 2021. Methods: Data on the incidence, prevalence, mortality, and disability-adjusted life year (DALY) rate of diabetes mellitus among population aged 15 to 39 years in China from 1990 to 2021 were collected from the Global Burden of Disease Study 2021 database. The disease burden of diabetes mellitus was analyzed by gender and age. The trend in disease burden among population aged 15 to 39 years was analyzed by average annual percent change (AAPC). Results: The incidence, prevalence and DALY rate of diabetes mellitus increased from 142.63/100 000, 1 826.41/100 000, and 138.04/100 000 in 1990 to 287.68/100 000, 5 245.93/100 000, and 316.82/100 000 in 2021, respectively, showing significant upward trends (AAPC=2.313%, 3.502% and 2.734%, all P<0.05). In contrast, the mortality decreased from 0.67/100 000 in 1990 to 0.57/100 000 in 2021, demonstrating a significant downward trend (AAPC=-0.518%, P<0.05). From 1990 to 2021, the incidences (AAPC=2.404% and 2.160%), prevalences (AAPC=3.576% and 3.389%), and DALY rates (AAPC=2.936% and 2.454%) of diabetes mellitus among males and females showed upward trends (all P<0.05). The mortality among females demonstrated a downward trend (AAPC=-1.809%, P<0.05), while the trend among males was not statistically significant (P>0.05). In 2021, the age group of 20 to <25 years had a relatively high incidence of diabetes mellitus, at 525.57/105. From 1990 to 2021, the incidences (AAPC=4.064%, 3.828%, 1.757%, 1.026% and 0.810%), prevalences (AAPC=2.374%, 3.625%, 3.371%, 2.985% and 2.647%), and DALY rates (AAPC=1.045%, 2.723%, 2.787%, 2.289% and 1.876%) of diabetes mellitus in age groups of 15 to <20 years, 20 to <25 years, 25 to <30 years, 30 to <35 years, and 35 to 39 years showed upward trends (all P<0.05). Conversely, the mortality (AAPC=-2.480%, -1.164%, -0.724%, -0.979% and -1.139%) in these age groups demonstrated downward trends (all P<0.05). Conclusion The overall disease burden of diabetes mellitus among population aged 15 to 39 years in China showed an upward trend, with males and the age group of 20 to <25 years being key target populations for diabetes mellitus prevention and control.

G protein-coupled receptor 120(GPR120)is one of the membrane receptors for long chain free fatty acids and is distributed in alveolus macrophages and airway epithelial Club cells.GPR120 activation alleviates the inflammation of respiratory tract,improves airway hyper-responsiveness,stimulates proliferation of Club cells and promotes the repair of respiratory epithelium,which may attenuate asthma and acute lung injury.

Objective To compare the effects of functional end-to-end esophagojejunostomy(FETE method)and side-to-side esophagojejunostomy with cis-peristalsis(overlap method)on post-operative rehabilitation,anastomotic leakage,and inflammatory-oxidative stress factors in patients un-dergoing laparoscopic radical resection for esophageal cancer.Methods A total of 115 patients with esophageal cancer were selected as study subjects,and were randomly divided into overlap group(n=57)and FETE group(n=58)using random number table method,and both groups underwent lapa-roscopic radical resection for esophageal cancer.The overlap group received the overlap method,and the FETE group received the FETE method.The surgical-related indicators,postoperative recovery indicators,incidence of anastomotic leakage,inflammatory factors[interleukin-10(IL-10),interleu-kin-6(IL-6),tumor necrosis factor-α(TNF-α)],oxidative stress factors[malondialdehyde(MDA),superoxide dismutase(SOD)],pulmonary function indicators[forced vital capacity(FVC),forced expiratory volume in one second(FEV1),FEV1/FVC],and the scores of the esophageal cancer-specific quality of life questionnaire(QLQ-OES18)were compared between the two groups.Results There was no statistically significant difference in intraoperative blood loss between the two groups(P＞0.05).The FETE group had shorter operative time and intraoperative anastomosis time,and a lar-ger number of lymph node dissection compared with the overlap group,with statistically significant differences(P＜0.05).The FETE group had earlier postoperative first flatus time,first oral intake time,and drainage tube removal time compared with the overlap group,with statistically significant differences(P＜0.05).The incidence of anastomotic leakage was 1.72％in the FETE group and 7.02％in the overlap group,with no statistically significant difference(P＞0.05).One week after surgery,the serum levels of IL-10,IL-6,TNF-α and MDA in the FETE group were lower than those in the overlap group,while the serum SOD level was higher,with statistically significant differences(P＜0.05).One week after surgery,the FVC,FEV,and FEV1/FVC in the FETE group were higher than those in the overlap group,with statistically significant differences(P＜0.05).Three months after surgery,the QLQ-OES18 functional domain scores in the FETE group were higher than those in the overlap group,while the symptom domain and single symptom domain scores were low-er,with statistically significant differences(P＜0.05).Conclusion Both the FETE method and the overlap method can reduce intraoperative blood loss and the incidence of anastomotic leakage when applied in laparoscopic radical resection for esophageal cancer.However,FETE method has shorter operative time,larger number of intraoperative lymph node dissections,faster postoperative recovery,and patients have less inflammatory-oxidative stress response and pulmonary function im-pairment,as well as higher quality of life after surgery,showing greater advantages compared with the overlap method.

Pectus excavatum (PE) is a common congenital chest malformation in children, manifested by inward depression of the anteriorthorax wall, which can compress the normal tissues and organs in the chest and cause adverse effects on the physiology and psychology of patients. Surgery is the most important means of treating PE, and with the invention of Nuss surgery, the surgical treatment of PE has entered the minimally invasive era. At present, there are many indexes to evaluate the severity of thoracic malformations in PE patients, and selecting appropriate evaluation indexes is of great significance for the formulation of surgical protocols. As a physical and mental disease, PE's deformed thoracic appearance not only affects the function of thoracic organs, but also affects the psychological state of patients. Therefore, there is still controversy over whether the role of orthopedic surgery is to improve function or cosmetic plastic surgery. At the same time, the orthopedic efficacy and postoperative complications of the existing modified and novel surgical methods need to be further observed and evaluated. In addition, the design of surgical plan and the selection of surgical timing for PE combined with other diseases are also critical and controversial issues in clinical practice. Therefore, this article explores and reviews the controversial points in the current surgical treatment of PE.

Chronic Guillain-Barre syndrome, also known as chronic inflammatory demyelinating polyradiculoneuropathy(CIDP), is an immune-mediated demyelinating peripheral neuropathy. This article analyzes the clinical data of a CIDP patient presenting primarily with limb numbness, pain, and weakness. Along with literature review, this study explores the differential diagnosis between CIDP and diabetic peripheral neuropathy in terms of the pathogenesis, clinical manifestations, laboratory tests, and treatment.

Objective To investigate the inhibitory effects of pyruvate-ferredoxin oxidoreductase(PFOR)by luteolin and its anti-Clostridium difficile effect.Methods The PFOR encoding sequence of Clostridium difficile was cloned into the expression vector pET-2a and transformed into competent Escherichia coli.The crude enzyme was prepared after induction with IPTG(Isopropyl β-D-Thiogalactoside).The inhibitory rate of the test compounds on PFOR was determined after an 8-hour anaerobic reaction between PFOR and 40 μmol·L-1 of test compounds at 25℃.The minimum inhibitory concentration(MIC)of PFOR inhibitors against C.difficile strains(ATCC BAA 1382 and ATCC BAA 1870)was determined by monitoring the OD600 of the bacterial culture.Molecular docking was performed to investigate the possible interaction mechanisms between PFOR and inhibitors.Results Among the tested compounds,the luteolin showed the strongest inhibitory activity against PFOR,with a single-point inhibition rate of approximately 33%,which is comparable to that observed with the positive inhibitor nitazoxanide(40%).Molecular docking revealed that luteolin could form hydrogen bonds with Asp428,Val431,Gly429,Asp456,Lys458,Lys459,and other residues in the PFOR domain.The MIC of luteolin against C.difficile was approximately 32 μg·mL-1.Conclusion Luteolin exhibits good activity against C.difficile,and PFOR may be a target for its antibacterial action.
