The expression level of NOD-like receptors(NLRP3)inflammasome is significantly elevated in breast cancer tissues,and a high level of NLRP3 inflammasomes is closely associated with breast cancer metastasis.Activation of NLRP3 inflammasome can induce the release of inflammatory factors into the tumor microenvironment(TME).These inflammatory factors,by signaling to cancer cells,reshape the TME to promote tumor growth and invasion,ultimately facilitating the process of epithelial-mesenchymal transition.This equips cancer cells with the ability to establish distant metastases and increase the formation of metastatic lesions.This review addresses the current research status and prospects of NLRP3 inflammasomes in the breast cancer TME and their role in breast cancer metastasis.The goal is to provide new insights for the study of breast cancer metastasis mechanisms and treatment strategies.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

ObjectiveTo investigate the quality variation of Lonicera japonica flower from different harvesting periods by ultraviolet visible(UV-Vis) fingerprint combined with chemometrics. MethodTwenty-five L. japonica flower samples from five harvesting periods, including young bud stage,green bud stage,white bud stage,silver and golden flower stages, were collected, with five samples for each stage. UV-Vis fingerprints of L. japonica flower from different harvesting periods were established in the context of the optimum extraction method based on the single factor experiment. The results showed that the absorption values at 209,216,226,250,280,303,318, and 350 nm were significantly different. Moreover,after data pretreatment and normalization,multivariate statistical analyses, such as principal component analysis (PCA),partial least squares discriminant analysis (PLS-DA),and orthogonal PLS-DA (OPLS-DA)were performed by SIMCA-P+ to establish the quality variation model of L. japonicas flower from harvesting periods. ResultAs revealed by PCA and PLS-DA, L. japonicas flower samples from five harvesting periods were clustered separately and closely in a harvesting time-dependent manner, suggesting that the content of components contained in samples from different harvesting periods was highly distinct and correlated with harvesting periods. The pairwise comparison of OPLS-DA indicated that triterpenoids or volatile oils were the main components causing the changes from the young bud stage to the green bud stage,and the content of them decreased. The main components from the green bud stage to the white bud stage were triterpenoids (or iridoids),volatile oils,phenolic acids, or flavonoids,and the content of them decreased, which was consistent with the HPLC result of chlorogenic acid. From the white bud stage to the silver flower stage, the main components were iridoids (increasing in content) and triterpenoids (or volatile oils) (decreasing in content). The main altered components from the silver flower stage to the golden flower stage were triterpenoids (or volatile oils) whose content increased. ConclusionThis method is simple and feasible, which can provide references for the quality control of Chinese medicine.

Objective: To analyze the influencing factors of healthy life expectancy (HLE). Methods: Seven Chinese and English databases were used for the retrieval of related literatures published by May 7, 2022 to identify influencing factors of HLE, including diseases and injuries and their risk factors. Based on the ecological model of health determinants, this study classifies the risk factors of diseases and injuries into five levels: personal characteristics, individual behavior and lifestyle, social network, living and working conditions, and macroscopic socio-economic, cultural and environmental conditions. Contents of research area, HLE indicators, research population, influencing factors, data sources and results were extracted. The frequencies of reported documents of different HLE indicators and influencing factors of different dimensions were visualized by using evidence map, and the empirical studies of four authoritative English medical journals and Chinese core medical journals were further compared and described. Results: A total of 90 studies were selected, in which 26 were conducted in China (28.9%). Fifty-three studies are about diseases and injuries in the first dimension, and all of them have studied non-communicable diseases, accounting for the highest proportion (58.9%). There were 77 studies about the analysis on the determinants of health at five levels by an ecological model, all the studies reported multi-level results. Among them, 53 studies reported personal characteristics (58.9%), 47 studies reported individual behavior and lifestyle (52.2%), 10 studies reported social networks (11.1%), 35 studies reported living and working environment (38.9%), 8 studies reported social economy, culture status and environment condition (8.9%). The literatures about HLE published by 4 authoritative English medical journals and 21 Chinese core medical journals in recent three years were selected. Non-communicable diseases and personal characteristics were the top two most commonly studied factors of HLE, and 11 (52.3%) and 12 (57.1%) studies reported these two kinds of factors respectively. The most important factor contributing to the global disability-adjusted life years of non-communicable diseases was individual behavior and lifestyle, which was the most changeable factor. Conclusions: In recent three years, studies involving influencing factors of HLE were mainly non-communicable diseases and personal characteristics. In the future, individual behavior, lifestyle and working environment should be strengthened.

The advancement of the next generation sequencing (NGS) technology has promoted the development of ancient DNA research. Ancient DNA has made outstanding contributions in various fields such as human origin, animal evolution, etc. How to effectively extract and mine the genetic information from fossil and sub-fossil remains excavated from specific locations is a prerequisite for optimizing their important roles in many fields. In this study, we correlated the two main indicators of DNA damage (terminal base replacement rate, average fragment length) with the possible factors such as the burial time, geological epochs, tissue types, and sequencing library construction methods. The results show that the end base replacement rate of ancient DNA from Northeastern China is positively correlated with the water content of the environment and the ages of the samples. Among samples of different geological epochs, ancient DNA end base replacement rates have significant differences. On the contrary, different tissue types of the remains have no significant effects on the end base replacement rate of ancient DNA. The average fragment size of the molecules has no obvious correlation with the factors mentioned above. The results provide both solid data for investigating the characteristics of ancient DNA from specimens collected in Northeastern China, and valuable information for collecting appropriate samples from different geographical locations and the downstream storage before wet lab procedures after excavation.

Objective:
: Shunt infection is a common complication while treating hydrocephalus. The antibiotic-impregnated shunt catheter (AISC) was designed to reduce shunt infection rate. A meta-analysis was conducted to study the effectiveness of AISCs in reduction of shunt infection in terms of age, follow-up time and high-risk patient population.
Methods:
: This study reviewed literature from three databases including PubMed, EMBASE, and Cochrane Library (from 2000 to March 2019). Clinical studies from controlled trials for shunt operation were included in this analysis. A subgroup analysis was performed based on the patient’s age, follow-up time and high-risk population. The fixed effect in RevMan 5.3 software (Cochrane Collaboration) was used for this meta-analysis.
Results:
: This study included 19 controlled clinical trials including 10105 operations. The analysis demonstrated that AISC could reduce the infection rate in shunt surgery compared to standard shunt catheter (non-AISC) from 8.13% to 4.09% (odds ratio [OR], 0.48; 95% confidence interval [CI], 0.40–0.58; p=0.01; I2=46%). Subgroup analysis of different age groups showed that AISC had significant antimicrobial effects in all three groups (adult, infant, and adolescent). Follow-up time analysis showed that AISC was effective in preventing early shunt infections (within 6 months after implant). AISC is more effective in high-risk population (OR, 0.24; 95% CI, 0.14–0.40; p=0.60; I2=0%) than in general patient population.
Conclusion
: The results of meta-analysis indicated that AISC is an effective method for reducing shunt infection. We recommend that AISC should be considered for use in infants and high-risk groups. For adult patients, the choice for AISC could be determined based on the treatment cost.

Prunella vulgaris(PV) is an edible and traditional medicinal herb which has a wide range application in fighting inflammation and oxidative stress, and protecting liver. Now it has been used to treat various types of liver diseases and has significant clinical efficacy. This study aims to investigate the effects of PV on ethanol-induced oxidative stress injury in rats and its metabolic mechanism. The rats were divided into control group, model group, PV group, and VC group. The liver protection of PV was identified by measuring pharmacological indexes such as antioxidant and anti-inflammatory activity. The metabolic mechanism of long-term ethanol exposure and the metabolic regulation mechanism of PV treatment were studied by LS-MS metabonomics. The pharmacological investigation indicated that ethanol could significantly decrease the contents of SOD, GSH-Px, CAT and other antioxidant enzymes in liver and increase the content of MDA. At the same time, PV could significantly reduce the contents of inflammatory factors(TNF-α, IL-6 and IL-1β) and liver function markers(ALT, AST, ALP) in serum. What's more, long-term ethanol exposure could significantly cause liver injury, while PV could protect liver. Metabolomics based on multiple statistical analyses showed that long-term ethanol exposure could cause significant metabolic disorder, and fatty acids, phospholipids, carnitines and sterols were the main biomarkers. Meanwhile, pathway analysis and enrichment analysis showed that the β oxidation of branched fatty acids was the main influencing pathway. Also, PV could improve metabolic disorder of liver injury induced by ethanol, and amino acids, fatty acids, and phospholi-pids were the main biomarkers in PV treatment. Metabolic pathway analysis showed that PV mainly regulated metabolic disorder of ethanol-induced liver injury through phenylalanine, tyrosine and tryptophan biosynthetic pathways. This study could provide a new perspective on the hepatoprotective effect of natural medicines, such as PV.
