Objective: To assess the effect of 12-year-old children s pit and fissure sealants on the health of first permanent molars, so as to provide evidence for optimizing caries prevention strategies among children. Methods: In March 2025, a cluster random sampling method was used to conduct oral examinations on 965 students aged 12 from Chengdu s 2021 Comprehensive Intervention Program for Pediatric Oral Diseases. Data from the Comprehensive Intervention System for Children s Oral Diseases were referenced. Participants were divided into a sealed group ( n =755) and an unsealed group ( n =210) based on whether they had received sealants on their first permanent molars. Chi square test or analysis of variance were used to compare indicators such as caries incidence, new caries detection rate, and new caries mean (DMFT increment) between the two groups Results: The sealed group showed significantly lower caries incidence, new caries detection rate, and new caries mean (33.38%, 17.65%, 0.59±1.00) compared to the unsealed group (43.81%, 24.70%, 0.87±1.22)( χ 2/F =7.79, 18.26, 9.55, all P <0.05). However, no significant difference was found in the filled teeth ratio between the two groups (20.38% , 20.16%; χ 2=0.01, P =0.94). In girls, the sealed group exhibited significantly lower caries incidence, new caries detection rate, and new caries mean (36.78%, 20.99%, 0.69± 1.10 ) than the unsealed group (57.55%, 33.52%, 1.15±1.29) ( χ 2/F =14.42, 23.76, 10.92, all P <0.05), whereas no significant differences were observed between boys in the sealed (30.47%, 14.85%, 0.50±0.89) and unsealed groups (29.81%, 16.18%, 0.59± 1.08) ( χ 2/F =0.02, 0.41, 0.74, all P >0.05). Boys had significantly lower new caries detection rates and new caries means than girls in both groups ( χ 2/F =16.20, 6.94; 29.93, 11.84, all P <0.05). In urban areas, the sealed group had lower new caries detection rates and new caries means (19.37%, 0.68±1.04) than the unsealed group (24.66%, 0.90±1.20) ( χ 2/F =6.86, 3.94, both P <0.05). In suburban areas, all indicators for the sealed group (24.71%, 13.77%, 0.42±0.87) were significantly lower than those for the unsealed group (38.81%, 24.77%, 0.82±1.28) ( χ 2/F =5.28, 15.36, 6.00, all P <0.05). Indicators from specialized dental institutions (11.25%, 4.81%, 0.16±0.56) were significantly lower than those from county level or above general hospitals (33.33%, 19.11%, 0.38±1.00) and primary healthcare institutions (37.59%, 19.24%, 0.67±1.05) ( χ 2/F =20.99, 34.31, 21.08 , all P <0.01). Conclusions The 12-year-old children s pit and fissure sealants effectively reduce the caries incidence in first permanent molars, particularly showing significant effectiveness in girls and suburban children. Intervention strategies should be optimized according to gender.

Objective To systematically evaluate the risk prediction models for anastomotic leakage (AL) in patients with esophageal cancer after surgery. Methods A computer-based search of PubMed, EMbase, Web of Science, Cochrane Library, Chinese Medical Journal Full-text Database, VIP, Wanfang, SinoMed and CNKI was conducted to collect studies on postoperative AL risk prediction model for esophageal cancer from their inception to October 1st, 2023. PROBAST tool was employed to evaluate the bias risk and applicability of the model, and Stata 15 software was utilized for meta-analysis. Results A total of 19 literatures were included covering 25 AL risk prediction models and 7373 patients. The area under the receiver operating characteristic curve (AUC) was 0.670-0.960. Among them, 23 prediction models had a good prediction performance (AUC>0.7); 13 models were tested for calibration of the model; 1 model was externally validated, and 10 models were internally validated. Meta-analysis showed that hypoproteinemia (OR=9.362), postoperative pulmonary complications (OR=7.427), poor incision healing (OR=5.330), anastomosis type (OR=2.965), preoperative history of thoracoabdominal surgery (OR=3.181), preoperative diabetes mellitus (OR=2.445), preoperative cardiovascular disease (OR=3.260), preoperative neoadjuvant therapy (OR=2.977), preoperative respiratory disease (OR=4.744), surgery method (OR=4.312), American Society of Anesthesiologists score (OR=2.424) were predictors for AL after esophageal cancer surgery. Conclusion At present, the prediction model of AL risk in patients with esophageal cancer after surgery is in the development stage, and the overall research quality needs to be improved.

Autophagy is a conservative lysosome-dependent material catabolic pathway, and exists in all eukaryotic cells. Autophagy controls cell quality and survival by eliminating intracellular dysfunction substances, and plays an important role in various pathophysiology processes. Erectile dysfunction (ED) is a common male disease. It is resulted from a variety of causes and pathologies, such as diabetes, hypertension, hyperlipidemia, aging, spinal cord injury, or cavernous nerve injury caused by radical prostatectomy, and others. In the past decade, autophagy has begun to be investigated in ED. Subsequently, an increasing number of studies have revealed the regulation of autophagy contributes to the recovery of ED, and which is mainly involved in improving endothelial function, smooth muscle cell apoptosis, penile fibrosis, and corpus cavernosum nerve injury. Therefore, in this review, we aim to summarize the possible role of autophagy in ED from a cellular perspective, and we look forward to providing a new idea for the pathogenesis investigation and clinical treatment of ED in the future.

Non-human primates are the closest relatives of human beings and possess similar morphological， anatomical， physiological， and behavioral characteristics， making them indispensable in fields such as neuroscience， reproduction， infectious diseases， and drug research and development. Currently， the restrictions on using non-human primates in experiments are becoming increasingly stringent in Europe and the United States. These experiments have ethical particularities that are different from those involving ordinary animals， and they also pose ethical challenges such as lack of necessity assessment， no unified assessment standards， and ethical dumping hazards. Supervision and ethical review should be strengthened. The key points of their ethical review include the necessity of the experiments， the assessment of the harm-benefit ratio， and the implementation of the “3R” principles.

Objective To examine the current status and trends of colorectal cancer (CRC) burden among Chinese residents from 1990 to 2021. Methods Data on CRC burden in China, Asia, and the global population from 1990 to 2021 were retrieved from the Global Burden of Disease database for descriptive analysis. An age-period-cohort model was employed to estimate the effects of age, period, and cohort on CRC mortality and to forecast changes in disease burden. Results In 2021, China’s age-standardized mortality rate, prevalence rate, and DALY rate for CRC were higher than global and Asian averages. The estimated annual percentage changes (EAPC) from 1990 to 2021 were −0.49% (95%CI: −0.55% to −0.43%) for mortality, 3.17% (95%CI: 3.03%−3.31%) for prevalence, and −0.62% (95%CI: −0.71% to −0.54%) for DALYs. Areas with high and medium-high sociodemographic indexes (SDIs) showed significant decreases in standardized mortality and DALY rates, but these rates remained higher compared with other regions. CRC mortality increased with age in the Chinese population, more prominently in males than in females. Using the 2002–2006 period as a reference (RR=1), the period effect on CRC mortality risk for women was higher than that for men until 2004, after which it declined considerably. With the 1957 birth cohort as a reference (RR=1), CRC mortality risk generally decreased across subsequent birth cohorts. Predictions indicate that by 2035, the standardized prevalence rate will be 267.21 per 100 000, and the standardized mortality rate will be 12.29 per 100 000. Conclusion From 1990 to 2021, China’s age-standardized CRC mortality and DALY rates have decreased, while the standardized prevalence rate has increased. These findings suggest the government to establish a comprehensive multi-level CRC prevention network.

ObjectiveTo investigate the influence of platelet-albumin-bilirubin （PALBI） score on the textbook outcome （TO） of patients with hepatocellular carcinoma （HCC） after hepatectomy， as well as the association of different PALBI scores before surgery with the achievement of TO after hepatectomy in HCC patients. MethodsA retrospective analysis was performed for the data of HCC patients who underwent hepatectomy in West China Hospital of Sichuan University and Ziyang Central Hospital from January 2013 to January 2022. TO was defined as no serious complication within 30 days after surgery， no death within 90 days， no rehospitalization within 30 days after discharge， no blood transfusion in the perioperative period， RO resection， and no prolongation of hospital stay. The chi-square test was used for comparison of categorical data between two groups. The univariate and multivariate Logistic regression analyses were used to investigate the influencing factors for the achievement of TO after hepatectomy in HCC patients. The Kaplan-Meier method was used to plot the survival curves of HCC patients， and the Log-rank test was used for comparison. ResultsA total of 3 599 patients were included in this study， among whom 2 369 （65.8%） achieved TO. The multivariate Logistic regression analysis showed that PALBI grade （PALBI grade 2： odds ratio ［OR］=1.562， 95% confidence interval ［CI］： 1.308‍ ‍—‍ ‍1.864， P<0.001； PALBI grade 3： OR=2.216， 95%CI： 1.463‍ ‍—‍ ‍3.359， P<0.001） was an independent risk factor for achievement of TO after surgery in HCC patients. The proportion of patients achieving TO decreased with the increase in PALBI grade. Among the patients with PALBI grade 1， 2 or 3， the patients achieving TO accounted for 70.2%， 54.2%， and 38.4%， respectively （χ²=106.295， P<0.001）. The incidence rate of serious complications within 30 days， the mortality rate of patients within 90 days after hepatectomy， readmission rate within 30 days after discharge， perioperative blood transfusion rate， and the rate of prolonged hospital stay all increased with the increase in PALBI grade （all P<0.05）. For the patients achieving TO， the 1-， 3-， and 5-year relapse-free survival rates were 79.5%， 60.6%， and 51.5%， respectively， and the overall survival rates were 92.1%， 80.0%， and 71.1%， respectively； for those who did not achieve TO， the 1-， 3-， and 5-year relapse-free survival rates were 68.5%， 52.7%， and 46.2%， respectively， and the overall survival rates were 83.3%， 66.0%， and 57.1%， respectively. The patients who achieved TO had significantly better relapse-free survival rate and overall survival rate than those who did not achieve TO （χ²=18.936 and 79.371， both P<0.001）. ConclusionPreoperative PALBI grade can affect the achievement of TO after hepatectomy in HCC patients， and it is more difficult for patients with a higher PALBI grade to achieve TO. Preoperative PALBI score can be used to early identify the patients with a high risk of postoperative complications， provide early intervention， and enhance perioperative management， thereby improving the perioperative safety and long-term prognosis of HCC patients after hepatectomy.
