[Purpose]To analyze the prevalence characteristics and disease burden of lung cancer in Hebei cancer registration areas from 2012 to 2020.[Methods]Lung cancer data were collected from the Hebei Provincial Cancer Registry from 2012 to 2020.The crude incidence/mortality rates,age-standardized incidence/mortality rates by Chinese standard population(ASIRC/ASMRC)and by world standard population(ASIRW/ASMRW)were calculated.The Joinpoint model was used to calculate the annual percentage change(APC)and average annual percentage change(AAPC).Years of life lost(YLL)and years lived with disability(YLD)and the disability-adjusted life years(DALY)were calculated.[Results]From 2012 to 2020,the ASIRW of lung cancer in Hebei can-cer registration areas was 33.13/105,44.56/105 for men and 22.54/105 for women,respectively;the incidence rates of urban and rural areas were 29.05/105 and 33.52/105,respectively.The incidence rates increased with ages,reaching a peak in the age group of 80～84 years old.There was a de-creasing trend in the ASIRW of lung cancer(AAPC=-3.99％,P＜0.05).From 2012 to 2020,the ASMRW of lung cancer was 25.80/105,36.56/105 for men and 15.96/105 for women,respectively;the mortality rates of urban and rural areas were 25.14/105 and 26.12/105,respectively.The mor-tality rates increase with ages,reaching a peak in the age group of 85 and above years old.There was a decreasing trend in the mortality of lung cancer(AAPC=-4.65％,P＜0.001)from 2012 to 2020.The DALY of lung cancer in Hebei Province from 2012 to 2020 was 484 194 person-years,with male accounting for 66.77％,female accounted for 33.23％,the DALY rate of lung cancer was 3.31‰,of which 35.57％in urban areas and 64.43％in rural areas.[Conclusion]Lung can-cer incidence and mortality rate in Hebei cancer registration areas from 2012 to 2020 showed a decreasing trend.The disease burden is gradually increasing with age in middle-aged and el-derly population.

Objective:To explore the relationship between general demographic characteristics,inflammatory indicators,nutritional indicators,pathological data and lymph node metastasis in endometrial cancer(EC)pa-tients,and to construct and validate a model for preoperative prediction of lymph node status in endometrial canc-er patients.Methods:The preoperative clinical data of 473 patients with EC who underwent surgical treatment in the Zhu Jiang Hospital of Southern Medical University from January 2010 to April 2024 were retrospectively ana-lyzed.The independent risk factors of lymph node metastasis of endometrial cancer were screened by univariate and multivariate Logistic regression analyses,and the nomogram prediction model was constructed by R soft-ware.The performance of the model was evaluated by the receiver operating characteristic(ROC)curve,calibra-tion curve and clinical decision curve.Results:Menopausal status,high grade biopsy pathology,CA125 ≥24.47U/ml,systemic immune inflammatory index(SII)≥710.91,and prognostic nutritional index(PNI)＜52.90 were in-dependent risk factors for lymph node metastasis in endometrial cancer(OR＞1,P＜0.05).The nomogram model constructed based on these five factors had an AUC of 0.853 in the training set and 0.871 in the test set.The cali-bration curve fitted well,and the clinical decision curve shows a positive benefit.Conclusions:The endometrial cancer lymph node metastasis prediction model constructed based on menopausal status,biopsy pathology,CA125,SII,and PNI has good accuracy and fit,with certain clinical application value.

Acute kidney injury (AKI) is a critical clinical condition characterized by rapid renal function decline, with high morbidity, mortality, and healthcare costs. Traditional Chinese medicine (TCM) has shown potential effects on mitigating oxidative stress and programmed cell death in AKI models. Scutellaria barbata D. Don (SB) and Scleromitrion diffusum (Willd.) R. J. Wang (SD), a classic TCM herbal pair exhibited anti-inflammatory and antioxidant activities. Using advanced chromatographic separation technology, we enriched the effective fractions of water extracts from SB-SD, obtaining self-assembled herbal nanoparticles (SB and SD nanoparticles, SSNPs) rich in flavonoids and terpenoids. These SSNPs demonstrated robust antioxidant properties in vitro and mitigated AKI progression in vivo by activating the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway. Oral administration of SSNPs in mice resulted in absorption into the bloodstream, formation of a protein corona, reduced macrophage phagocytosis, and enhanced bioavailability and renal targeting. Furthermore, we investigated the self-assembly principle of SSNPs using representative flavonoids and terpenoids. Kinetic studies and in situ transmission electron microscopy (in situ TEM) revealed that these compounds self-assemble via supramolecular forces like hydrogen bonding and π-π interactions, forming stable nanostructures. This study elucidates the renoprotective effects and mechanisms of SB and SD, and provides a novel approach for the development of TCM-based nanomedicines, highlighting the potential of nano-TCM in AKI treatment.

Hypoxemia is a common pathological state characterized by low oxygen saturation in the blood. This condition compromises mucosal barrier integrity particularly in the gut and oral cavity. However, the mechanisms underlying this association remain unclear. This study used periodontitis as a model to investigate the role of platelet activation in oral mucosal immunopathology under hypoxic conditions. Hypoxia upregulated methyltransferase-like protein 4 (METTL4) expression in platelets, resulting in N⁶-methyladenine modification of mitochondrial DNA (mtDNA). This modification impaired mitochondrial transcriptional factor A-dependent cytosolic mtDNA degradation, leading to cytosolic mtDNA accumulation. Excess cytosolic mt-DNA aberrantly activated the cGAS-STING pathway in platelets. This resulted in excessive platelet activation and neutrophil extracellular trap formation that ultimately exacerbated periodontitis. Targeting platelet METTL4 and its downstream pathways offers a potential strategy for managing oral mucosa immunopathology. Further research is needed to examine its broader implications for mucosal inflammation under hypoxic conditions.

[Purpose]To analyze the incidence,mortality and disease burden of malignant tumors in the cancer registration areas of Hebei Province in 2020.[Methods]The incidence and mortality data of cancer in 2020 were collected from the cancer registries of Hebei Province,and the quality of data was evaluated.The crude incidence(mortality)rate,age-specific incidence(mortality)rates and age-standardized incidence(mortality)rates by Chinese standard population(ASIRC/ASMRC)and world standard population(ASIRW/ASMRW)were calculated and analyzed.The disability-ad-justed life years(DALY)were calculated and analyzed according to the Excel disease burden cal-culation template recommended by the World Health Organization(WHO).[Results]In 2020,the crude incidence rate,ASIRC,ASIRW of malignant tumors in the cancer registration areas of Hebei Province were 229.36/105,147.06/105 and 143.74/105,respectively.The incidence rate in men was higher than that in women.The incidence rates in urban and rural areas were 230.26/105 and 228.84/105,and the age-standardized incidence rates reached a peak in the age group of 80～84 years old.The crude mortality rate,ASMRC,ASMRW were 146.38/105,85.33/105 and 84.79/105,respectively.The mortality rate in men was higher than that in women.The age-standardized mor-tality rate rose with age,reaching a peak in the age group of 85+years old,and the crude mortality rates in urban and rural areas were 143.82/105 and 147.84/105,respectively.The DALY of ma-lignant tumors in the cancer registration areas of Hebei Province were 345 030 person-years,reaching a maximum in the age group of 45～59 years old,with a DALY rate of 15.00/103,and the highest in the age group of 70～79 years old.Lung cancer had the heaviest disease burden,with DALY of 83 684 person-years,accounting for 24.25％of all malignant tumors,followed by stomach,liver,female breast,and colorectal cancers.The DALY in urban and rural areas were 122 062 and 222 993 person-years,respectively,and the trends in DALY rates were basically stable.[Conclusion]The disease burden of malignant tumors in Hebei Province is relatively heavy,cancer prevention and control should be further strengthened and focused on urban men and the elderly to reduce disease burden of malignant tumors in the future.

OBJECTIVE: To observe the effects of moxibustion at "Shenque" (CV8) on urodynamics and the expression of brain-derived neurotrophic factor (BDNF) and immediate early gene (c-fos) in pontine micturition center (PMC), periaqueductal gray (PAG), medial prefrontal cortex (mPFC) of neurogenic bladder (NB) rats after spinal cord injury. METHODS: Twenty-four SPF female SD rats were randomly divided into a sham-operation group (6 rats) and a modeling group (18 rats). In the modeling group, T₉ complete spinal cord transection method was used to establish a neurogenic detrusor overactivity model, and the 12 rats with successful modeling were randomized into a model group and a moxibustion group, with 6 rats in each group. The rats in the moxibustion group were treated with ginger/salt-insulated moxibustion at "Shenque" (CV8), and 4 consecutive moxa cones were delivered in one intervention. Moxibustion was operated once daily and for 14 days. After intervention completion, the urodynamic indexes of rats in each group were detected. Fluorescence quantitative PCR was used to detect the mRNA expression of BDNF and c-fos in PMC, PAG and mPFC in rats. Western blot was used to detect the protein expression of BDNF and c-fos in PMC, PAG and mPFC. RESULTS: The rats in the sham-operation group did not show phasic detrusor contraction during bladder filling. Compared with the model group, the frequency and amplitude of the phasic detrusor contraction were reduced 5 min before urine leakage in the rats of the moxibustion group (P<0.05), and the duration of the first phasic detrusor contraction during bladder filling was prolonged (P<0.05). Compared with the sham-operation group, the mRNA and protein expression of BDNF and c-fos in PMC, PAG and mPFC increased in the model group (P<0.05). Compared with the model group, the mRNA and protein expression of BDNF and c-fos in PMC, PAG and mPFC decreased in the moxibustion group (P<0.05). CONCLUSION Moxibustion at "Shenque" (CV8) can improve the phasic contraction during bladder filling in NB rats after spinal cord injury, possibly by down-regulating the mRNA and protein expression of BDNF and c-fos in PMC, PAG, and mPFC.

After being treated with acupuncture, some patients with idiopathic tinnitus may experience a short-term aggravation of tinnitus symptoms on the original basis. These symptoms can be gradually relieved and the overall condition fluctuates towards recovery. This phenomenon has brought some difficulties to patients and clinicians. Based on the academic view of TCM, "destroying pathogens and re-building balance", and in association with the existing understanding of acupuncture in modern medicine for tinnitus, this paper briefly discusses the mechanism and influencing factors of symptom fluctuation in patients with idiopathic tinnitus after acupuncture treatment in terms of both TCM and modern medicine, and proposes the future direction in the research of symptom fluctuation, so as to promote the recognition of clinicians and patients on symptom fluctuation and make rational use of its positive effects. Besides, it is hoped that more researchers will pay attention to symptom fluctuation and advance the exploration of it in academic field.

Depression and circadian rhythms exhibit bidirectional interactions,suggesting a close association with the biological clock system.The biological clock in the suprachiasmatic nucleus of the hypothalamus is regulated by circadian genes.Recent clinical and basic research has revealed multifaceted associations between depression and circadian genes.For instance,significant phase abnormalities in BMAL1,PER2,and PER3 were detected in brain tissue from depressed patients,while plasma levels of CRY1,ARNTL,and PER1 proteins showed marked reduction,demonstrating good diagnostic value.Mice with CLOCK and BMAL1 knockouts exhibited depression-like behaviors.Single nucleotide polymorphisms(SNPs)in genes such as PER1 and PER3 directly influence depression susceptibility.Methylation levels of BMAL1,PER3,and CLOCK genes correlate closely with depressive symptoms.Antidepressant mechanisms like ketamine exert their effects by downregulating PER2 and other genes.This review summarizes the differential expression patterns of circadian clock genes in depression and associated therapeutic approaches,aiming to provide new theoretical foundations for precision diagnosis and personalized treatment strategies for depression.

Objective:With the aggravation of population aging, the burden of malignant tumors in the elderly population is becoming more and more heavy. This study aims to analyze the incidence and mortality of malignant tumors in the elderly population in Hebei Province in the past decade.Methods:The incidence and mortality data of malignant tumors in people aged ≥60 years old in 38 cancer registration areas in Hebei Province from 2011 to 2020 were collected, and the incidence and mortality were analyzed by gender, urban and rural areas, and age groups. The age standardized rates were calculated using the 2000 Chinese population census and Segi′s world population. The trend of incidence and mortality was analyzed using the Joinpoint model and the average annual percent change (AAPC).Results:From 2011 to 2020, 216 200 new cases of malignant tumors were reported in the elderly population in the cancer registration areas of Hebei Province, and 170 700 deaths were reported. The peak ages of incident cases number for males and females were 65-69 years old and 60-64 years old, respectively. The crude incidence rate of malignant tumors in the elderly was 905.42/10 5, and the crude mortality rate was 714.96/10 5. In general, the incidence and mortality in rural areas were higher than those in urban areas, and the incidence and mortality in males were higher than those in females. The peak ages of incidence and mortality were 80-84 years old and 85+ years old, respectively. From 2011 to 2020, lung cancer, gastric cancer, esophageal cancer, female breast cancer, and colorectal cancer were the main malignant tumors of incidence rate in the elderly population in Hebei Province, and lung cancer, gastric cancer, liver cancer, esophageal cancer, and colorectal cancer were the main malignant tumors in the mortality rate. From 2011 to 2020, the incidence and mortality of malignant tumors in the elderly population in Hebei Province showed a decreasing trend, and AAPC for the age-standardized incidence and mortality were -4.69% and -5.53%, respectively. The rank of incidence and mortality rate of each cancer had changed, but the top two were still lung cancer and stomach cancer. Conclusions:The incidence and mortality of cancer in the elderly population in Hebei province have decreased, but the burden is still heavy. Lung cancer and stomach cancer are still the focus of prevention and treatment in the elderly population in Hebei province.
