The c-Jun N-terminal kinase （JNK） signaling pathway， a key member of the mitogen-activated protein kinase （MAPK） family， plays a central role in the pathogenesis and progression of central nervous system （CNS） diseases by regulating core biological processes such as apoptosis， inflammatory responses， synaptic plasticity， and autophagy. This article sorts out and analyzes relevant literature published domestically and internationally in recent years， summarizing the mechanisms of action of the JNK signaling pathway in common CNS diseases and the research progress in traditional Chinese medicine （TCM） interventions in CNS diseases through the regulation of the JNK signaling pathway. Studies have shown that active components of TCM， such as berberine， paeoniflorin， and astragaloside Ⅳ， as well as compound formulations like Heixiaoyao san， Ditan tang， and Buyang huanwu tang， can exert neuroprotective effects in various CNS disorders， including Alzheimer’s disease， Parkinson’s disease， cerebral ischemia-reperfusion injury， and epilepsy， by inhibiting the aberrant activation of the JNK signaling pathway， thereby alleviating neuroinflammation， oxidative stress， and neuronal apoptosis， while improving synaptic function and cognitive behavioral deficits， regulating autophagy， and maintaining blood-brain barrier integrity.

Prostate cancer is one of the most common malignant tumors of male genitourinary system. Prostate cancer has the following characteristics： insidious onset， early asymptomatic or not obvious symptoms， complex etiology and pathogenesis， long incubation period and so on. Therefore， the realization of its early diagnosis and treatment is of great significance to the prognosis of patients. Prostate-specific membrane antigen （PSMA） is a type 2 transmembrane glycoprotein that is highly expressed on the membrane of almost all primary and metastatic prostate cancer cells， and is an ideal target for prostate cancer imaging and treatment. In recent years， with the approval of urea-containing small molecule PET （positron emission computed tomography） radiopharmaceutical based on PSMA （⁶⁸Ga-PSMA-11， ¹⁸F-PSMA-1007）， PET-CT （positron emission computed tomography/computed tomography） has shown new potential for early diagnosis and accurate staging of prostate cancer patients. This review mainly summarizes the research progress of urea-containing PSMA PET imaging agents and finds that they have defects such as uptake in non-target tissues like the kidneys， lacrimal glands， and salivary glands. Thus， further optimizing their structure to reduce the uptake in non-target tissues， providing provide convenience for the labeling of therapeutic radiopharmaceuticals， thereby achieving the goal of integrated diagnosis and treatment， is an important development direction in this field.

Alzheimer’s disease （AD） is an age-related neurodegenerative disorder. Marrow-sea insufficiency serves as the fundamental basis for the onset of AD. Early syndrome differentiation-based intervention helps to delay disease progression， and improve patients’ cognitive function. Qifu yin is a representative specialized prescription for AD with marrow-sea insufficiency syndrome. Studies demonstrate that Qifu yin exerts neuroprotective effects through multiple pathways， including inhibiting the abnormal deposition of amyloid β -protein and hyperphosphorylation of tau protein， alleviating neuroinflammation， regulating oxidative stress and mitochondrial dysfunction， modulating the cholinergic system， and improving synaptic plasticity. Qifu yin combined with Western medicine such as donepezil， memantine， and butylphthalide， or combined with external therapies such as acupuncture， can effectively improve cognitive function and activities of daily living in AD patients with favorable safety. Future research should focus on the core pathogenesis and key targets of AD with marrow-sea insufficiency syndrome， provide in-depth elucidation of the scientific connotation of Qifu yin’s “tonifying the kidney to produce marrow”， and further conduct high-quality clinical studies to provide scientific evidence for the prevention and treatment of AD with marrow-sea insufficiency syndrome.

ObjectiveTo explore the changes in volatile components， total polysaccharides， enzyme activity， and chromaticity value of Myristicae Semen Koji（MSK） during the fermentation process， and conduct correlation analysis. MethodsBased on gas chromatography-mass spectrometry（GC-MS）， the changes of volatile components in MSK at different fermentation times were identified. The phenol sulfuric acid method， dinitrosalicylic acid method（DNS）， and carboxymethyl cellulose sodium salt method（CMC-Na） were used to investigate the total polysaccharide content， amylase activity， and cellulase activity during the fermentation process. Visual analysis technology was used to explore the changes in chromaticity values， revealing the fermentation process of MSK and the dynamic changes of various measurement indicators， partial least squares-discriminant analysis（PLS-DA） was used to explore the differential compounds of MSK at different fermentation degrees， and Pearson correlation analysis was used to explore the correlation between volatile components of MSK and total polysaccharides， enzyme activity， and chromaticity values. ResultsA total of 60 volatile compounds were identified from MSK， the relative contents of components such as （+）-α-pinene， β-phellandrene， β-pinene， （+）-limonene， and p-cymene obviously increased， while the relative contents of components such as safrole， methyl isoeugenol， methyleugenol， myristicin， and elemicin significantly decreased. During the fermentation process， the total polysaccharide content showed an upward trend， while the activities of amylase and cellulase showed an initial increase followed by a decrease， and reached their maximum value at 40 h. the overall brightness（L^*） and total color difference（ΔE^*） gradually increased， while the changes in red-green value（a^*） and yellow-blue value（b^*） were not obvious. PLS-DA results showed that MSK could be clearly distinguished at different fermentation times， and 13 differential biomarkers were screened out. Pearson correlation analysis results showed that the contents of α-terpinene， β-phellandrene， methyleugenol， β-cubebene and myristic acid had an obvious correlation with chromaticity values. ConclusionAfter fermentation， the volatile components， total polysaccharides， amylase activity， and cellulase activity of MSK undergo significant changes， and there is a clear correlation between them and chromaticity values， which reveals the dynamic changes in the fermentation process and related indicators of MSK， laying a foundation for the quality control.

Xiaoaiping (XAP) Injection demonstrates the anti-prostate cancer (PCa) effects, yet the underlying mechanism remains unclear. This study aims to investigate the impact of XAP on PCa and elucidate its mechanism of action. PCa cell proliferation was evaluated using a cell counting kit-8 (CCK-8) assay. Cell apoptosis was assessed through Hoechst staining and Western blotting assays. Proteomics technology was employed to identify key molecules and significant signaling pathways modulated by XAP in PCa cells. To further validate potential key genes and important pathways, a series of assays were conducted, including acridine orange (AO) staining, transmission electron microscopy, and immunofluorescence assays. The molecular mechanism of XAP against PCa in vivo was examined using a PC3 xenograft mouse model. Results demonstrated that XAP significantly inhibited cell proliferation in multiple PCa cell lines. In C4-2 and prostate cancer cell line-3 (PC3) cells, XAP induced cellular apoptosis, evidenced by reduced B-cell lymphoma 2 (Bcl-2) levels and elevated Bcl-2-associated X (Bax) levels. Proteomic, immunofluorescence, and quantitative reverse transcription-polymerase chain reaction (qRT-PCR) investigations revealed a strong correlation between forkhead box O3a (FoxO3a) autophagic degradation and the anti-PCa action of XAP. XAP hindered autophagy by reducing the expression levels of autophagy-related protein 5 (Atg5)/autophagy-related protein 12 (Atg12) and enhancing FoxO3a expression and nuclear translocation. Furthermore, XAP exhibited potent anti-PCa action in PC3 xenograft mice and triggered FoxO3a nuclear translocation in tumor tissue. These findings suggest that XAP induces PCa apoptosis via inhibition of FoxO3a autophagic degradation, potentially offering a novel perspective on XAP injection as an effective anticancer therapy for PCa.

Objective:To improve the isolation and culture method of seasonal influenza virus in embryonated chicken eggs (ECEs), and evaluate their isolation efficiency.Methods:We randomly selected 80 positive samples of H1N1 (H1N1pdm09) and seasonal H3N2 (H3N2snl) influenza virus nucleic acid, and inoculated them into the amniotic and urinary sac cavities of 10-day-old (traditional method) and 14-day-old (improved method) ECEs respectively to adapt the virus to the ECEs (E1-E2). Both method were used to inoculate 10-day-old urinary sac amplification virus (E2-E3), and the final virus isolation positive rates of the two method were compared; using fluorescence quantitative PCR method to detect viral nucleic acids in the improved amniotic and urinary sac cultures, and evaluate the viral proliferation at different inoculation sites; we analyzed the correlation between virus content and isolation positivity rate in the original specimen based on the CT value of nucleic acid testing and the final virus isolation positivity rate using the improved method.Results:The improved method obtained 42 strains of H1N1pdm09 strain, with a positive rate of 52.5% ( χ2=38.571, P<0.01); obtained 54 strains of H3N2snl strain, with a positive rate of 67.5% ( χ2=40.921, P<0.01). Significant differences were observed in the isolation efficiency of H1N1pdm09 samples when the improved method was applied to different inoculation sites of chicken embryos ( χ2=30.476, P<0.01), and similar differences were noted for H3N2snl samples ( χ2=4.928, P=0.026). There was no significant difference in the isolation rate of different CT value intervals of the original samples ( χH1N1pdm092=10.226, χH3N2snl2=3.764, P>0.05). Conclusions:The improved method of inoculating 14-day old ECEs adapted the virus, and the final number of strains obtained was significantly higher than the traditional method of inoculating 10 day old ECEs, which can significantly improve the positive isolation rate of H1N1pdm09 and H3N2snl influenza virus in ECEs. The amniotic cavity is more sensitive to H1N1pdm09 and H3N2snl influenza viruses, which helps the virus adapt in ECEs. There was no significant difference in the sample isolation rate and total positive rate of virus isolation among different CT value ranges, and further verification is needed.

Objective:To investigate the prevalence and risk factors of overweight and obesity among Chinese children aged 3-18 years from 11 provinces, antonomous regions, or municipalities.Methods:This national cross-sectional community health survey utilized a multistage stratified cluster-random sampling method to recruit 193 997 nationally representative participants from 11 provinces, autonomous regions, or municipalities between January 2017 and December 2019. All participants underwent physical examinations, and their caregivers completed questionnaires assessing participants′ dietary, lifestyle, familial, and perinatal information. Multilevel multinomial logistic regression models were employed to identify the potential risk factors.Results:The cohort comprised 193 997 children (102 178 boys, 91 819 girls),aged (10±4) years. Overall prevalence rates were 30 574(15.8%)overweight children and 17 217(8.9%) obesity children. Boys exhibited higher overweight and obesity rates than girls (17.0% (17 368/102 178) vs. 14.4% (13 206/102 178), 11.3% (11 553/91 819) vs. 6.2% (5 664/91 819), χ2=249.12,1 578.69,both P<0.001). The detection rates of obesity in Tanner stage 2 and 3 were the highest in boys and girls, with 13.4%(2 231/16 665) and 8.6%(880/10 221) respectively. Risk factors for obesity included parental overweight (paternal OR=2.34 and maternal OR=2.29), annual household income of 100 000-200 000 yuan (compared with<100 000 yuan, OR=1.04), higher paternal education (compared with below high school,high school and a college education OR=1.09,1.14), birth weight >4.0 kg (≤5 and>5 years old OR=1.74, 1.44,respectively), and western food consumption≥1 time/month (compared with<1, 1-2, 3-4,>4 times/month OR=1.36, 1.30, 1.67(≤5 years), 1.19, 1.16, 1.15 (>5 years), respectively) (all P<0.05). Conversely, coarse grain intake≥1 times/week (compared with<1 times/week, every day, 3-4, 1-2 times/week OR=0.74, 0.80, 0.71 (≤5 years), 0.75, 0.87, 0.90(>5 years), respectively, all P<0.05) was associated with reduced obesity risk. Conclusions:Obesity epidemiology in children demonstrates significant heterogeneity across age, gender, geographic regions, and pubertal stages. It is necessary to establish a personalized prevention and control strategy.

Objective:To observe the efficacy and safety of subcutaneous stripping combined with gold radiofrequency dot matrix microneedles in the treatment of atrophic acne scar.Methods:A total of 122 patients with atrophic acne scar in Dongying People′s Hospital from January 2023 to January 2024 were prospectively included and divided into two groups by random number table method: Observation group, 61 patients, including 37 males and 24 females, aged 20-43 (31.5±4.7) years, received subcutaneous stripping combined with gold radiofrequency dot matrix microneedles; Control group, 61 patients, including 33 males and 28 females, aged 22-44 (32.6±4.5) years, were treated with subcutaneous dissection. Patients in both groups were treated once every 4 weeks for a total of 3 times. The total effective rate, skin barrier function, wound recovery time, scar condition and adverse reactions were compared between the two groups.Results:The total effective rate of the observation group was 93.4% (57/61), which was higher than that of the control group [75.4% (46/61), P=0.005]. After treatment, the corneum protein content, lactate stimulation test score, skin erythema (a value), and transdermal water loss (TEWL) of the observation group were (29.52±3.22) μg, (1.72±0.18) min, 15.10±2.21, and (18.31±3.35) g/(h·m 2), respectively. They were lower than those (35.24±4.17) μg, (2.75±0.24) min, 19.14±2.57, and (21.23±4.52) g/(h·m 2) in the control group (all P<0.001). The wound healing time, shedding time and scab time in the observation group were (3.42±0.67), (6.57±1.21) and (1.73±0.32) d, respectively, which were shorter than those (5.31±0.99), (8.26±1.48) and (2.85±0.47) d in the control group (all P<0.001). The acne scar clinical score scale (ECCA) and Vancouver scar scale (VSS) scores in the observation group were (38.10±5.29) and (5.23±0.82) points, respectively, which were lower than those (43.65±6.44) and (6.34±0.97) points in the control group (all P<0.001). The incidence of adverse reactions was 11.5% (7/61) in the observation group and 8.2% (5/61) in the control group, the difference was not statistically significant ( P=0.540). Conclusion:Subcutaneous stripping combined with gold radiofrequency dot matrix microneedles is effective in the treatment of atrophic acne scars, which can improve skin barrier function, shorten wound recovery time, and improve scar symptoms with good safety.

Objective:To clarify the genetic associations between obesity, diabetes, smoking, non-alcoholic fatty liver disease, acute and chronic pancreatitis, and pancreatic cancer risk.Methods:Summary data from genome-wide association studies (GWAS) of individuals of European descent were used. Obesity, alcohol consumption, diabetes, and acute and chronic pancreatitis data for the UK population were obtained from the GWAS catalog, while alcohol consumption, non-alcoholic fatty liver disease, occasional smoking, and regular smoking data were obtained from the UK biobank. Pancreatic cancer-related data for the Finnish population were sourced from the latest R11 version of the Finnish database. Two-sample Mendelian randomization (MR) analysis was conducted on the associations between the aforementioned risk factors and pancreatic cancer using five MR methods, primarily inverse variance weighting. The robustness of the results was assessed through Q heterogeneity tests, pleiotropy tests, MR-PRESSO analysis, and reverse MR analysis.Results:Obesity showed a significant positive association with pancreatic cancer risk ( OR=1.407, 95% CI: 1.100-1.714, P=0.030), and the results were robust based on Q heterogeneity tests, pleiotropy tests, MR-PRESSO, and reverse MR analysis (all P>0.05). However, no significant associations were found between pancreatic cancer risk and alcohol consumption ( P=0.330), heavy drinking ( P=0.382), type 1 diabetes ( P=0.674), type 2 diabetes ( P=0.825), occasional smoking ( P=0.607), regular smoking ( P=0.758), non-alcoholic fatty liver disease ( P=0.287), acute pancreatitis ( P=0.336), or chronic pancreatitis ( P=0.545). Conclusion:This study further confirms the strong genetic association between obesity and increased pancreatic cancer risk.

AIM:This study aims to investigate the regulatory effect of the endocannabinoid 2-arachidonoyl glycerol(2-AG)on voltage-gated calcium channels(VGCCs)in caudate nucleus(CN)neurons subjected to kainic acid(KA)-induced damage,and to elucidate the underlying mechanisms involved.METHODS:Primary cultured CN neu-rons from neonatal Sprague-Dawley(SD)rats were treated with KA to establish an excitotoxic cellular model.The whole-cell patch-clamp technique was utilized to assess the effects of 2-AG on KA-induced excitotoxicity,along with the changes in the electrical properties of VGCCs.This included evaluations of current density,current-voltage relationships,and the kinetics of channel activation and inactivation.RESULTS:Treatment with KA significantly increased the current density and altered the electrical properties of VGCCs,as indicated by a reduction in the half-inactivation voltage and a shift of the inactivation curve towards depolarized potentials.Notably,KA did not affect the activation characteristics of VGCCs.Ad-ministration of exogenous 2-AG or the application of the monoacylglycerol lipase inhibitor URB602,which inhibits 2-AG degradation and elevates intracellular levels of 2-AG,effectively inhibited the KA-induced increase in VGCC current den-sity and the depolarization shift of the inactivation curve,highlighting the involvement of cannabinoid receptor 1(CB1R).CONCLUSION:The endocannabinoid 2-AG can modulate the function of VGCCs in CN neurons via the CB1R pathway,offering protective effects against excitotoxic damage induced by KA.
