Objective:To explore the spatial clustering of the mortality rate of cervical cancer in different counties (cities, districts) in Shandong Province from 1970 to 2021 and its 50-year changing trend, so as to provide basis for the implementation and evaluation of prevention and control strategies and programs such as cervical cancer screening, early diagnosis and treatment, human papilloma virus (HPV) vaccination, etc.Methods:The mortality data of cervical cancer were obtained from the death registration system of Shandong Province and the data of three retrospective surveys of death causes. The mortality rate and age-standardized mortality rate (using the population composition of China in 1964) are used to describe the changing trend of cervical cancer in different years. The contribution values of population factors and non-population factors in cervical cancer mortality change are calculated by mortality differential decomposition method. ArcGIS 10.8 software is used for spatial distribution and spatial autocorrelation analysis.Results:From 1970 to 2021, the crude mortality rate and age standardized mortality rate of cervical cancer in Shandong Province showed a trend of first rapid decline and then slow increase. The crude mortality rate and standardized mortality rate of female cervical cancer in Shandong Province in 1970-1974 were the highest, reaching 17.22/10 5 and 13.17/10 5, respectively. In 2004-2005, it dropped to the lowest levels of 1.50/10 5 and 0.83/10 5. Subsequently, it slowly rose to 4.12/10 5 and 1.56/10 5 in 2020-2021. The differential analysis of cervical cancer mortality in different years found that the change of cervical cancer mortality was caused by the combined action of population factors and non-population factors. Among them, demographic factors (aging population) led to the increase of cervical cancer mortality, but non-demographic factors (early diagnosis and treatment, HPV infection level, medical technology level, etc) lead to the decrease of cervical cancer mortality. Compared with 1970-1974, with the passage of time, the absolute values of the contribution values of population factors and non-population factors showed an increasing trend, while the contribution of non-population factors was greater than that of population factors, which led to the decline of cervical cancer mortality. From the perspective of spatial distribution, there were great regional differences in the mortality rate of cervical cancer in different counties of Shandong Province. In 2020-2021, the mortality rate of cervical cancer in all counties decreased to a great extent compared with that in 1970-1974, and the high-high and low-low concentration areas of cervical cancer mortality in different years changed obviously. The high-aggregation areas of the cervical cancer mortality rate in Shandong Province from 2020 to 2021 were mainly distributed in some counties and districts of Linyi City, Zaozhuang City, and Heze City in the southwest. Conclusions:There are significant temporal and spatial changes in the mortality rate of cervical cancer in Shandong Province from 1970 to 2021. According to these trends and their geographical and spatial clustering, prevention and control strategies of cervical cancer in different regions should be further formulated and evaluated.

Objective To explore the effect of esketamine on the early mental state of patients after modified radical mastectomy.Methods From August 2022 to September 2024,95 patients with breast cancer who received modified radical mastectomy in Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine were selected and divided into control group(48 cases)and experimental group(47 cases)according to random number table method.Patients in both groups were routinely anesthetised and underwent type Ⅱ thoracic nerve block under ultrasound guidance.The experimental group was given a single intravenous injection of esketamine 0.25mg/kg before incision,while the control group was injected with the same amount of physiological saline.The incidence of adverse reactions,visual analogue scale(VAS)score,brain-derived neurotrophic factor(BDNF),tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),Hamilton depression scale(HAMD)score,Hamilton anxiety scale(HAMA)score,functional assessment of cancer therapy-breast(FACT-B)score were all compared between two groups.Results On the 1st and 3rd day after surgery,the levels of TNF-α and IL-1β,the scores of HAMA and HAMD in experimental group were significantly lower than those in control group,and the level of BDNF was significantly higher than that in control group(P＜0.05).The FACT-B score of experimental group was significantly higher than that of control group at the first clinic after surgery(P＜0.05).On the first day after surgery,there were no significant differences in the incidence of nausea,vomiting,hallucination,nightmare,agitation,lethargy and VAS score between two groups(P＞0.05).Conclusion The subanesthetic dose of esketamine combined with type Ⅱ thoracic nerve block can improve the early postoperative mental status of patients undergoing modified radical mastectomy.

Objective:To explore the predictive value of triglyceride-glucose (TyG) index combined with low-density lipoprotein cholesterol (LDL-C) for major adverse cardiovascular events (MACE) in patients with coronary heart disease (CHD) complicated by type 2 diabetes mellitus (T2DM).Methods:A total of 248 patients with CHD and T2DM admitted to the First Affiliated Hospital of Xinjiang Medical University from July 2022 to January 2024 were retrospectively enrolled. All patients were followed up for 2 years and divided into MACE group (43 cases) and non-MACE group (205 cases) according to the occurrence of MACE. Indicators such as TyG index and LDL-C were compared between the two groups, and their correlations with MACE were analyzed. Multivariate logistic regression was used to screen the risk factors for MACE in patients with CHD and T2DM. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of TyG index, LDL-C, and their combination for MACE in these patients.Results:Compared with the non-MACE group, the MACE group had significantly higher LDL-C [2.63(2.23, 2.95)mmol/L vs 1.99(1.60, 2.66)mmol/L, P<0.001] and TyG index [9.30(8.80, 9.87) vs 8.60(8.09, 9.15), P<0.001]. Multivariate logistic regression showed that TyG index was an independent risk factor for MACE in patients with CHD and T2DM ( OR=10.49, P<0.001). ROC curve results indicated that the area under the curve (AUC) of TyG index and LDL-C for predicting MACE were 0.731 and 0.686, respectively. The combined AUC of the two indicators for predicting MACE was 0.769(95% CI: 0.698-0.840), showing better predictive performance. Conclusions:TyG index combined with LDL-C has high predictive value for the risk of MACE in patients with CHD complicated by T2DM.

Objective: To analyze the effects of health literacy on overweight and obesity among primary school students and their parents in terms of salt, oil and sugar reduction (referred to as the "three reductions"), so as to provide a theoretical basis for the development of obesity control measures. Methods: From March to April 2024, a total of 1 022 fourthgrade primary school students and 913 parents were surveyed in 24 classes in six counties in Shandong Province using multistage cluster random sampling, and physical measurements of primary school students were conducted. Pearsons correlation analysis and ordered multivariate Logistic regression were used to investigate the associations between health literacy of primary school students and their parents with overweight and obesity among children. Results: The detection rates of overweight and obesity primary school students in Shandong Province were 14.87% and 24.66%, respectively, with significant sex difference in obesity rate (29.46% for boys and 19.76% for girls) (χ2=12.93, P<0.01). In addition to students reducing oil scores, parental reducing salt,reducing oil,reducing sugar, comprehensive health literacy scores and students reducing salt,reducing sugar and comprehensive health literacy scores showed a negative relationship with students overweight and obesity (r=-0.10, -0.08, -0.07, -0.10, -0.04, -0.07, -0.03, P<0.05). The overweight and obesity rates among primary school students with high parental reducing salt,reducing oil,reducing sugar and composite health literacy scores were lower (OR=0.69, 0.69, 0.71, 0.63, P<0.05); and the overweight and obesity rate among students with high parental and low parental and high and low parental health literacy scores were lower (OR=0.68, 0.57, P<0.05). Conclusion Improving health literacy regarding "three reductions" for parents and children, especially parents, can effectively reduce the risk of childhood overweight and obesity.

OBJECTIVE To investigate the improvement effects and its mechanism of Bazheng powder on chronic urinary tract infection （CUTI） induced by Escherichia coli in rats. METHODS The rats were divided into normal control group， model group， levofloxacin group （45 mg/kg） and Bazheng powder group （4.95 g/kg）， with 10 rats in each group. Except for the normal control group， other groups were administered an intravesical injection of Escherichia coli suspension （1×10⁸ cfu/mL） via the urethra to establish CUTI model； at the same time， rats in each group were administered the corresponding medicinal solution or water by gavage once a day for 4 consecutive weeks. After the last medication， blood routine tests （white blood cell count and lymphocyte percentage）， the levels of serum inflammatory factors [interleukin-1β （IL-1β）， IL-6， IL-8， tumor necrosis factor-α （TNF-α）]， and immune indicators [CD4， CD8， secretory immunoglobulin A （SIgA）]， renal function indicators [cystatin C （Cys-C）， α1- microglobulin （α1-MG）， urea and creatinine] were all determined； the pathological changes in renal and bladder tissues in rats were observed. The protein expressions of Toll-like receptor 4 （TLR4）， nuclear factor-κB （NF-κB）， and nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 （NLRP3） in rat bladder tissues were detected. RESULTS Compared with the normal control group， the levels of IL-1β， IL-6， IL-8， TNF-α， CD8， Cys-C， α1-MG， urea and creatinine in serum， as well as the protein expressions of TLR4， NF-κB and NLRP3 in bladder tissues， were significantly elevated in the model group （P＜0.05）. Conversely， the levels of CD4 and SIgA were significantly decreased （P＜0.05）. Pathological changes， such as extensive infiltration of inflammatory cells， were observed in both renal and bladder tissues. Compared with the model group， the above quantitative indicators in the Bazheng powder group were significantly improved （P＜0.05）， with no obvious inflammatory lesions observed in either renal or bladder tissues. CONCLUSIONS Bazheng powder can alleviate inflammatory reaction and improve the immune function of CUTI rats， and its mechanism may be related to the inhibition of TLR4/NF-κB/ NLRP3 signaling pathway.

ObjectiveTo investigate the reversal effect of Cordyceps sinensis extract on immunotherapy resistance of non-small cell lung cancer （NSCLC）. MethodsELISA， flow cytometry， and co-culture assays were performed to evaluate the effects of Cordyceps sinensis extract on cytokine secretion， proliferation， and tumor cell killing activity of Jurkat （JKT） cells. Furthermore， the therapeutic effect of Cordyceps sinensis extract on programmed cell death ligand 1 （PD-L1） resistant lung cancer was evaluated through in vivo experiments both alone and in combination with anti-PD-L1 monoclonal antibody. ResultsCordyceps sinensis extract enhanced the secretion of cytokines interferon gamma（IFN-γ）， tumor necrosis factor-alpha（TNF-α） and interleukin-2 （IL-2）in JKT cells， promoted cell proliferation （P=0.006）， and boosted their killing function against tumors （P＜0.001）. Compared with the control group， in vivo study demonstrated that Cordyceps sinensis extract monotherapy effectively inhibited the growth of PD-L1-resistant tumors ［tumor growth inhibition value （TGI）=26.1%， P=0.090］， while its combination with anti-PD-L1 antibody significantly reversed PD-L1 resistance （TGI=50.6%， P＜0.001）. ConclusionThis study provides certain data support for the activation of anti-tumor immunity by Cordyceps sinensis extract， and offers a new treatment strategy for enhancing anti-tumor immunity and reversing immune resistance in lung cancer.

Background: Condyloma acuminatum (CA) is a common sexually transmitted disease caused by human papillomavirus (HPV). In recent years, research on anal CA has primarily focused on treatment rather than underlying mechanisms. The mechanism of HPV persistence and recurrence in CA require further exploration. It needs multiple researches in mechanisms to focalize treatment targets. Objective: To investigate the relationship between intestinal mucosal immunity and the relapse of anal CA and persistent infection. Methods: Levels of interferon gamma (IFN-γ) and secretory immunoglobulin A (sIgA) were measured using enzyme-linked immunosorbnent assay in anal mucosal cells obtained from patients treated at Tianjin Union Medical Center from September 2022 to December 2024. All the participants signed Informed Consent and the whole plan was approved by Institutional Review Board in Tianjin Union Medical Center (No. B155). Results: The levels of IFN-γ and sIgA significantly decreased after infection, and persistent infection exhibited even lower levels. These two factors increased following treatment, reaching peak concentrations at 4 weeks before decreasing again. Conclusion These findings demonstrate a significant association between persistent anal CA infection and dysregulation of intestinal mucosal immunity.

Objective:To understand spatial aggregation of lung cancer mortality and its changing trends over the past fifty years in different counties and districts of Shandong Province from 1970 to 2021.Methods:The mortality data of lung cancer were obtained from the death registration system of Shandong province and three retrospective surveys of death cause. The mortality rate and age-standardized mortality rate were used to describe the changing trend of lung cancer in different years, and the contribution value of population factors and non-population factors in lung cancer mortality change was calculated by the mortality differential decomposition method. GeoDa 1.20 and ArcGIS 10.8 software were used for spatial autocorrelation analysis and visualization map display.Results:The crude mortality rate of lung cancer in Shandong Province showed a significant upward trend from 1970 to 2021, rising from 7.22 per 100 000 in 1970-1974 to 62.73 per 100 000 in 2020-2021, with an increase of 7.69 times. Meanwhile, the standardized mortality rate of lung cancer exhibited a trend of increasing first and then decreasing. The differential analysis of lung cancer mortality in different years revealed that changes in crude mortality rates were the result of the combined effects of demographic and non-demographic factors. The proportion of population factors (aging population) leading to an increase in lung cancer mortality rate rose from 2.12% in 1990-1992 to 40.20% in 2020-2021. From a spatial distribution perspective, there were significant regional differences in lung cancer mortality rates among counties (cities, districts) in Shandong Province across different eras. Compared to the period of 1970-1974, the lung cancer mortality rates in all counties and districts in 2020-2021 showed a considerable increase, and there were noticeable changes in the areas of high-high and low-low clustering of lung cancer mortality rates across different eras.Conclusion:There have been significant temporal and spatial changes in the mortality rate of lung cancer in Shandong Province from 1970 to 2021. The crude mortality rate has shown an upward trend, while the standardized mortality rate increases first and then decreases. The concentration of lung cancer mortality rates in counties and districts has also undergone significant changes.

Objective Patients with acute coronary syndrome(ACS)combined with chronic kidney disease(CKD)are at high risk of major adverse cardiovascular events(MACE),and early prediction is crucial for improving prognosis.Non-invasive detection methods,due to their simplicity and safety,have become important tools for assessing risks in such patients.This study aims to evaluate the application value of non-invasive detection indicators in predicting MACE in ACS patients with CKD.Methods The study included 216 ACS patients with CKD,divided into a Non-MACE group(n=149)and a MACE group(n=67).General patient data,non-invasive detection indicators,electrocardiogram(ECG),and cardiac function indicators were collected.Univariate and multivariate logistic regression analyses were performed to explore the relationship between these indicators and MACE.A nomo-gram prediction model was constructed,and its performance was evaluated using ROC curve analysis,calibration curve,and decision curve analysis.Results Univariate analysis showed that age,BMI,SVR,SVRI,HRV,QTd,SDNN,LVEF,LVEDd,SCOPA-AUT score,and GRACE score were significantly associated with MACE.Multivariate analysis identified SVRI,QTd,SDNN,LVEF,LVEDd,SCOPA-AUT score,and GRACE score as independent risk factors for MACE.ROC curve analysis revealed that the model had an AUC value of 0.979,sensi-tivity of 0.925,specificity of 0.966,and accuracy of 0.9537,indicating high diagnostic accuracy.Calibration curve and decision curve analyses further confirmed the model's reliability.Conclusion Non-invasive detection indicators,including SVRI,QTd,SDNN,LVEF,LVEDd,SCOPA-AUT score,and GRACE score,have significant value in predicting MACE in ACS patients with CKD.The constructed prediction model provides an effective tool for clinical risk assessment.
