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.

ObjectiveTo investigate the mechanisms by which Bushen Tongluo Jiangzhuo prescription improves renal fibrosis in rats with chronic kidney disease (CKD) through the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway. MethodsSeventy specific pathogen-free (SPF) Sprague-Dawley (SD) rats were randomly divided into a control group (n=15) and a modeling group (n=55). Rats in the modeling group were administered a 2.5% adenine suspension at a dose of 200 mg·kg-1·d-1 by gavage for 4 weeks to establish a CKD model. Successfully modeled rats were randomly divided into a model group, an irbesartan group (20.25 mg·kg-1·d-1), and Bushen Tongluo Jiangzhuo prescription low-, medium-, and high-dose groups (5.82, 11.64, and 23.28 g·kg-1·d-1, respectively), with 10 rats in each group. Each group was administered an equal volume of physiological saline, the corresponding concentration of irbesartan, or Bushen Tongluo Jiangzhuo prescription by gavage for 12 weeks. Body weight and renal function indices were dynamically monitored. Serum creatinine (SCr), blood urea nitrogen (BUN), urine albumin-to-creatinine ratio (ACR), 24-hour urinary total protein (24 hUTP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) levels were measured using an automatic biochemical analyzer. Renal histopathological changes were observed by hematoxylin-eosin (HE) and Masson staining. Immunohistochemistry (IHC) was used to detect the expression of PI3K, Akt, phosphorylated Akt (p-Akt), and mTOR in renal tissues. Western blot was performed to assess the protein expression of PI3K, p-Akt, Akt, phosphorylated mTOR (p-mTOR), and mTOR in renal tissues. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to determine the mRNA expression levels of PI3K, Akt, and mTOR in renal tissues. ResultsCompared with the model group, rats in the irbesartan group and the low-, medium-, and high-dose Bushen Tongluo Jiangzhuo prescription groups showed significantly decreased levels of SCr, BUN, ACR, 24 hUTP, IL-1β, IL-6, and TNF-α (P<0.01). AST levels were significantly increased (P<0.01), while no significant difference was observed in ALT levels. Histopathological examination revealed that, compared with the model group, renal tubular epithelial cell edema and necrosis and Bowman's capsule dilation were alleviated, inflammatory cell infiltration was reduced, and interstitial and glomerular fibrosis was markedly improved in all treatment groups, with the most pronounced effect observed in the high-dose Bushen Tongluo Jiangzhuo prescription group. Real-time PCR results showed that mRNA expression levels of PI3K, Akt, and mTOR were significantly downregulated in the high-dose group (P<0.01). IHC results demonstrated that PI3K and p-Akt expression levels in renal tissues were significantly decreased in the high-dose group (P<0.01). Western blot analysis further confirmed that the expression levels of PI3K, p-Akt/Akt, and p-mTOR/mTOR were significantly reduced in the high-dose group (P<0.01). ConclusionBushen Tongluo Jiangzhuo prescription improves renal function indices in CKD rats, reduces collagen deposition in renal tissues, and decreases serum inflammatory factor levels. Its protective effect on renal function may be achieved by activating autophagy through downregulation of the PI3K/Akt/mTOR signaling pathway, thereby alleviating renal fibrosis.

ObjectiveTo investigate the mechanism of Tangbikang dry paste in the prevention and treatment of type 2 diabetic peripheral neuropathy (DPN) based on the glyoxalase-1 (GLO-1)/advanced glycation end products (AGE)/receptor for advanced glycation end products (RAGE) pathway. MethodsA total of 56 Sprague-Dawley rats were randomly divided, with eight assigned to the normal group. The remaining 48 rats were fed a high-fat diet combined with intraperitoneal injection of streptozotocin (STZ) to induce a type 2 diabetes mellitus (T2DM) model. Based on blood glucose levels, the rats were randomly assigned to the model group, Tanglin group (13.5 mg·kg-1), metformin group (135 mg·kg-1), and Tangbikang dry paste low-, medium-, and high-dose groups (3, 6, 12 g·kg-1). Successful modeling of DPN was confirmed by a decrease in mechanical pain threshold in the model group at week 4. Fasting blood glucose, body weight, and mechanical pain threshold were measured every 4 weeks. After 16 weeks of intervention, the pathological morphology of the sciatic nerve was observed using hematoxylin-eosin (HE) staining. The expression of RAGE, AGE, protein kinase C (PKC), and collagen (COL) in the sciatic nerve was assessed by immunohistochemistry. The mRNA expression of RAGE, PKC, Toll-like receptor (TLR), COL, and GLO-1 was detected using real-time quantitative PCR (Real-time PCR). Serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine (CREA), urea (UREA), interleukin-6 (IL-6), and tumor necrosis factor (TNF)-α were measured by enzyme-linked immunosorbent assay (ELISA). ResultsCompared with the normal group, the model group showed significantly increased fasting blood glucose (P<0.01), decreased body weight and mechanical pain threshold (P<0.01), and elevated serum AST, ALT, CREA, UREA, IL-6, and TNF-α levels (P<0.01). The expression of RAGE, AGE, and PKC in the sciatic nerve was significantly increased (P<0.01), while COL expression was decreased (P<0.01). The mRNA expression of TLR, RAGE, and PKC was upregulated (P<0.01), whereas COL and GLO-1 mRNA levels were downregulated (P<0.01). Histological examination showed irregular nerve morphology, axonal alterations, and myelin degeneration. Compared with the model group, fasting blood glucose levels in the Tangbikang dry paste high-dose group at all time points and in the medium-dose group at weeks 4 and 16 were significantly reduced (P<0.05, P<0.01). No significant changes in body weight were observed across all Tangbikang dose groups. The mechanical pain threshold was elevated at different time points after administration in all Tangbikang groups (P<0.05, P<0.01). Serum IL-6 and TNF-α levels were decreased in all dose groups (P<0.05, P<0.01). The expression of RAGE, AGE, and PKC in the sciatic nerve was reduced (P<0.01), while COL expression was increased (P<0.01). The mRNA expression of TLR, RAGE, and PKC was downregulated (P<0.01), whereas GLO-1 mRNA expression was upregulated (P<0.05, P<0.01). Additionally, COL mRNA expression was significantly increased in the low- and high-dose groups (P<0.01). Pathological changes in the sciatic nerve were milder in all Tangbikang groups compared to the model group. ConclusionTangbikang dry paste significantly improves DPN, and its mechanism may be associated with the regulation of the GLO-1/AGE/RAGE signaling pathway.

To review the randomized controlled trials (RCTs) at home and abroad on digital intelligence (DI)-driven rehabilitation in patients of neuromuscular disease, compare the effects of DI-driven rehabilitation with traditional rehabilitation, summarize the special needs and challenges faced by patients in rehabilitation of rare neuromuscular diseases, and provide evidence for the development and quality improvement of rehabilitation for rare neuromuscular diseases. We searched PubMed, Web of Science, Embase, CNKI, VIP, and Wanfang databases for literature on neuromuscular diseases, rare diseases, digital and intelligent technologies, and rehabilitation published from the inception of the databases to June 2024. Basic and research-related information from the retrieved literature was extracted and analyzed. A total of 43 RCTs in English from 14 countries were included. The most studied diseases were Parkinson′s disease and multiple sclerosis. The application of DI-driven technologies in rehabilitation of rare neuromuscular diseases was still limited. The commonly used technologies were virtual reality (VR) games, intelligent treadmill assistance, gait training robots, hybrid assistive limb (HAL), wearable sensors and tele-rehabilitation (TR) systems. These technologies were applied in patients′ homes or rehabilitation service centers. The VR games significantly improved both static/dynamic balance functions and cognitive functions. The intelligent treadmill assistance significantly enhanced gait speed and stride length. The gait training robots significantly improved balance, gait speed and stride length of patients. The wearable exoskeletons significantly enhanced walking ability. DI-driven rehabilitation measures have great value and potential in the field of neuromuscular disease rehabilitation. Their advantages and characteristics can meet the diverse needs of rare disease patients. In the future, a hierarchical and collaborative rehabilitation service system should be established to meet the urgent needs of the rehabilitation of rare neuromuscular diseases. Combining the advantages of digitization and intelligence will provide standardized, scientific, convenient and affordable rehabilitation services to patients.

To provide references to and give suggestions to the development and optimiza-tion of Digital Intelligence (DI) technology in management of non-hospitalized patients by systematical review the application of digital technology in non-hospital settings. We designed the search strategy and used the words " rare diseases"" patient management"" non-hospitalized management"" community management"" digital intelligence"" big data"" telemedicine" as MESH terms or free words. We searched the database of PubMed, Science-Direct, Web of Science, CNKI, Wanfang and VIP from the beginning of the database to July 2024 and used computer retrieval to get the literatures on the application of DI technology in the management of patients with rare diseases in non-hospital setting. We extracted the information of the first author, country or region, publication time, research participants, DI technology application, and application effect for summary analysis. A total of 13 articles were included in this study, which were from 8 countries or regions. We found that DI technologies used were in the following forms: Internet information platform, wearable devices, telemedicine management platform and electronic database. The DI technology was used by the patients with rare diseases, patient caregivers and professional medical staffs. The application of all the forms above in different populations had good effect. The Internet information platform helped patients and their caregivers learn more about the disease and improved their self-management ability. The wearable device helped monitor the health status of patients in real time and predict the risk of emergent events. The telemedicine management platform facilitated to optimize the allocation of medical resources and strengthen doctor-patient communication. The electronic health database promoted the interconnection of data inside and outside the hospital and improved the accuracy of decision-making through data sharing. The application of DI technology in the management of patients with rare diseases in non-hospitalized settings has shown positive results. In the future, it is necessary to correct the shortcomings and to deal with the challenges in terms of accuracy, readiness, applicability, and privacy protection. Besides, the DI can be integrated into the tri-level management system of patients known as the "patient-community-hospital". It is advisable to take the advantages of digital intelligence technology to improve the efficiency and quality of management of patients in non-hospitalized settings.
10.Role of Innate Trained Immunity in Diseases

The innate immune system can be boosted in response to subsequent triggers by pre-exposure to microbes or microbial products, known as “trained immunity”. Compared to classical immune memory, innate trained immunity has several different features. Firstly, the molecules involved in trained immunity differ from those involved in classical immune memory. Innate trained immunity mainly involves innate immune cells (e.g., myeloid immune cells, natural killer cells, innate lymphoid cells) and their effector molecules (e.g., pattern recognition receptor (PRR), various cytokines), as well as some kinds of non-immune cells (e.g., microglial cells). Secondly, the increased responsiveness to secondary stimuli during innate trained immunity is not specific to a particular pathogen, but influences epigenetic reprogramming in the cell through signaling pathways, leading to the sustained changes in genes transcriptional process, which ultimately affects cellular physiology without permanent genetic changes (e.g., mutations or recombination). Finally, innate trained immunity relies on an altered functional state of innate immune cells that could persist for weeks to months after initial stimulus removal. An appropriate inducer could induce trained immunity in innate lymphocytes, such as exogenous stimulants (including vaccines) and endogenous stimulants, which was firstly discovered in bone marrow derived immune cells. However, mature bone marrow derived immune cells are short-lived cells, that may not be able to transmit memory phenotypes to their offspring and provide long-term protection. Therefore, trained immunity is more likely to be relied on long-lived cells, such as epithelial stem cells, mesenchymal stromal cells and non-immune cells such as fibroblasts. Epigenetic reprogramming is one of the key molecular mechanisms that induces trained immunity, including DNA modifications, non-coding RNAs, histone modifications and chromatin remodeling. In addition to epigenetic reprogramming, different cellular metabolic pathways are involved in the regulation of innate trained immunity, including aerobic glycolysis, glutamine catabolism, cholesterol metabolism and fatty acid synthesis, through a series of intracellular cascade responses triggered by the recognition of PRR specific ligands. In the view of evolutionary, trained immunity is beneficial in enhancing protection against secondary infections with an induction in the evolutionary protective process against infections. Therefore, innate trained immunity plays an important role in therapy against diseases such as tumors and infections, which has signature therapeutic effects in these diseases. In organ transplantation, trained immunity has been associated with acute rejection, which prolongs the survival of allografts. However, trained immunity is not always protective but pathological in some cases, and dysregulated trained immunity contributes to the development of inflammatory and autoimmune diseases. Trained immunity provides a novel form of immune memory, but when inappropriately activated, may lead to an attack on tissues, causing autoinflammation. In autoimmune diseases such as rheumatoid arthritis and atherosclerosis, trained immunity may lead to enhance inflammation and tissue lesion in diseased regions. In Alzheimer’s disease and Parkinson’s disease, trained immunity may lead to over-activation of microglial cells, triggering neuroinflammation even nerve injury. This paper summarizes the basis and mechanisms of innate trained immunity, including the different cell types involved, the impacts on diseases and the effects as a therapeutic strategy to provide novel ideas for different diseases.
