Objective:To understand the epidemiological characteristics of severe fever with thrombocytopenia syndrome (SFTS) in Shandong province from 2010 to 2022, analyze the trends in morbidity and mortality, and provide a scientific basis for the prevention, control, diagnosis, and treatment of SFTS.Methods:The data on SFTS cases and deaths were retrospectively collected through the China Disease Control and Prevention Information System′s infectious disease surveillance system and the Shandong province all-cause mortality surveillance system. Descriptive epidemiological method was used for epidemiological analysis, and the Joinpoint regression model was applied to analyze trends in morbidity and mortality.Results:From 2010 to 2022, 6 714 SFTS cases were reported in Shandong, with an average crude incidence rate (CIR) and age-standardized incidence rate (ASIR) of 0.52/100 000 and 0.43/100 000, respectively. Among these, 1, 064 cases died within 30 days of onset, with an average crude mortality rate (CMR) and age-standardized mortality rate (ASMR) of 0.08/100, 000 and 0.06/100 000, respectively, and an average case fatality rate of 15.85%. The average incidence rates for males and females were 0.52/100 000 and 0.53/100 000, respectively, with no statistically significant difference ( P>0.05). The average annual mortality rate for males (0.09/100 000) was higher than that for females (0.08/100 000), and the average annual case fatality rate for males (17.21%) was higher than that for females (14.48%), with statistically significant differences ( P<0.05); 93.95% of the cases were over 45 years old, and 86.56% of the deaths were over 60 years old. Both cases and deaths were primarily among farmers, accounting for over 85% of the total. From 2010 to 2022, the incidence rate of SFTS in Shandong showed an overall upward trend, with an average annual percentage change (AAPC) in CIR of 23.58% and an AAPC in ASIR of 19.97%, P<0.05. The mortality rate of SFTS cases in Shandong from 2010 to 2022 showed a continuous and significant upward trend, with a CMR AAPC of 27.64% and an ASMR AAPC of 22.70%, P<0.05. SFTS incidence and mortality in Shandong exhibited clear seasonality, with high occurrence from May to October, primarily concentrated in the Jiaodong Peninsula and the hilly areas of central Shandong. The number of affected counties increased in a wave-like pattern, expanding from 6 in 2010 to 79 in 2021 for cases and from 2 in 2010 to 53 in 2022 for deaths. Conclusions:From 2010 to 2022, the incidence and mortality of SFTS in Shandong showed an upward and expanding trend, with a particularly heavy disease burden among middle-aged and elderly farmers.

Objective To investigate the relationship between the levels of serum suppressor of cytokine signaling 3(SOCS3),growth differentiation factor-15(GDF-15)and liver fibrosis in patients with type 2 dia-betes mellitus(T2DM)combined with non-alcoholic fatty liver disease(NAFLD).Methods A total of 320 patients with T2DM combined with NAFLD who were hospitalized in this hospital from May 2023 to May 2024 were selected as the study group,and another 320 patients with simple T2DM admitted during the same period were selected as the control group.The levels of serum SOCS3 and GDF-15 were determined by en-zyme-linked immunosorbent assay(ELISA).Pearson correlation analysis was used to analyze the correlation between SOCS3,GDF-15 levels and liver fibrosis indicators.Logistic regression analysis was used to analyze the factors affecting the degree of liver fibrosis.The receiver operating characteristic(ROC)curve was used to analyze the diagnostic value of serum SOCS3 and GDF-15 for the degree of liver fibrosis in patients.Results Compared with the control group,the levels of serum SOCS3,GDF-15,5,type Ⅲ procollagen peptide,laminin and type Ⅳ col-lagen in the study group were significantly increased(P＜0.05).There were statistically significant differ-ences in the levels of type Ⅲ procollagen peptide,laminin and type Ⅳ collagen between the mild to moderate group and the severe group(P＜0.05).Compared with the mild to moderate group,the levels of serum SOCS3 and GDF-15 in the severe group were significantly increased(P＜0.05).The results of Pearson corre-lation analysis showed that serum SOCS3 and GDF-15 in patients with T2DM combined with NAFLD were positively correlated with type Ⅲ procollagen peptide,laminin,and type Ⅳ collagen(P＜0.05).Serum SOCS3,GDF-1 5,type Ⅲ procollagen peptide,laminin and type Ⅳ collagen are risk factors affecting the degree of liver fibrosis in patients with T2DM combined with NAFLD(P＜0.05).The results of the ROC curve showed that the combined diagnosis of serum SOCS3 and GDF-15 for the degree of liver fibrosis in patients with T2DM complicated with NAFLD had the highest area under the curve(AUC),which was superior to the individual diagnosis of each(both P＜0.05),with a corresponding sensitivity of 69.08％and a specificity of 85.71％.The combined diagnosis of the degree of liver fibrosis in patients with T2DM complicated with NAFLD by serum SOCS3,GDF-15,type Ⅲ procollagen peptide,laminin,and type Ⅳ collagen had the highest AUC,which was superior to the individual diagnosis of each index(all P＜0.001),with a corresponding sensi-tivity of 89.47％and a specificity of 97.02％.Conclusion The levels of serum SOCS3 and GDF-15 are elevated in patients with T2DM combined with NAFLD,.The combined diagnosis of serum SOCS3,GDF-15,type Ⅲ procolla-gen peptide,laminin,and type Ⅳ collagen has a high value in the degree of liver fibrosis in patients.

Objective Methyltransferase 3(METTL3)mediated N6-methyladenosine(m6A)methylation modifica-tion of transient receptor potential cation channel subfamily M member 7(TRPM7)regulates ferroptosis and malig-nant progression in cervical cancer(CESC).Methods Totally 40 patients with cervical cancer were collected.Cer-vical cancer tissues and adjacent normal tissues(≥3 cm from the edge of the tumor tissue)were sampled at opera-tion and then divided into experimental group and control group,respectively.RT-qPCR and Western blot were used to detect the differences in TRPM7 mRNA and protein expression between the two groups.TRPM7-interfering cell lines were constructed to investigate the effects of TRPM7 on CESC cells.Cell proliferation and apoptosis were assessed using 5-ethynyl-2'-deoxyuridine(EdU)assay and flow cytometry,respectively.Transwell chamber assays were employed to evaluate cell invasion and migration capabilities.The levels of ferroptosis in CESC cells were measured using kits for reactive oxygen species(ROS),malondialdehyde(MDA),glutathione(GSH),and Fe2+.Bioinformatics tools were utilized to predict methyltransferases associated with TRPM7.The interaction between METTL3 and TRPM7 was examined through RNA immunoprecipitation(RIP)and methylated RNA immunoprecip-itation quantitative PCR(Me-RIP qPCR).The effect of METTL3 on the stability of TRPM7 expression was assessed using actinomycin D assay.Results TRPM7 was highly expressed in CESC tissue and cells.Knockdown of TRPM7 significantly inhibited cell proliferation,promoted cell apoptosis,suppressed cell migration and invasion capabilities,and enhanced ferroptosis levels(P＜0.05).Bioinformatics predictions suggested that METTL3 might act as a methyltransferase for TRPM7.Interference with METTL3 gene expression significantly reduced TRPM7 pro-tein levels,decreased TRPM7 m6A modification levels,and impaired TRPM7 gene stability(P＜0.05).Conclusions METTL3 regulates CESC proliferation,apoptosis,migration,invasion,and ferroptosis by m6A meth-ylation modification of the TRPM7 gene.

Spondyloarthritis (SpA) is a group of chronic inflammatory diseases which predominantly involve spine and/or peripheral joints. SpA can be disabling and seriously affect the quality of life and function of patients. With the increasing clinical use of targeted drug therapy, precise and standardized use becomes the focus. China's first Consensus on Targeted Drug Therapy for Spondyloarthritis was developed by National Clinical Research Center for Dermatologic and Immunologic Diseases using international norms for consensus development. The consensus addresses 13 important clinical questions, ranging from principles, patient eligibility, pre-treatment screening, treatment initiation, drug selection and switch, co-medication, to adverse event monitoring of targeted drug therapy in SpA, and recommends treatment for specific patients, playing a key role in guiding clinical practices.

Objective:To analyze the surveillance data of population in rabies exposure and post-exposure prophylaxis (PEP) clinics in Shandong province from 2019 to 2023, explore risk factors for exposure, and provide a basis for further standardizing PEP.Methods:Based on surveillance data from the rabies exposure treatment clinic vaccination information system, population, and spatial administrative division data in Shandong province from 2019 to 2023, descriptive epidemiological methods were applied to analyze using SPSS 18.0.Results:The number of individuals receiving post-exposure treatment at PEP clinics in Shandong province from 2019 to 2023 was over 1 million annually and showed an increasing trend year by year, with the highest number of visits occurring from May to August each year. The number of female patients is increasing year by year. The 15-year-old and younger age group accounted for 31.69%-36.86% of clinic visits. Grade Ⅲ exposures accounted for 53.40%, and limbs accounted for approximately 89.81% of exposed areas. Approximately 1.94% is multi site exposure. The main injuring animals were dogs, followed by cats, and the proportion of cats is increasing year by year. The proportion of doctor′s office visitors who self-treated wounds increased from 32.32% to 45.46%, while the proportion of outpatient wound treatment decreased from 76.07% to 66.24%. The whole course vaccination rate after initial exposure is 63.79%. The whole course vaccination rate for the 15-29-year-old age group was lower than that for other age groups. The usage rate of passive immune preparations among grade Ⅲ exposed individuals is 35.66%. From 2019 to 2023, 8 cases of rabies were reported, none of whom received standard post-exposure treatment.Conclusions:The epidemic characteristics and exposure risk of people exposed to suspected rabies animals in Shandong province have changed. It is necessary to pay attention to the female population, the population with low vaccination rate between 15 to 29 years of age, cat bitten people, and carry out continuous monitoring on the exposed population, and timely adjust the prevention and control strategies.

Objective To analyze the effect of dexmedetomidine(Dex)on biological behavior of A549 cells through expression of miR-1307.Methods Human lung cancer A549 cells were randomly divided into four groups after being cultured for 24 hours:Lung cancer A549 cell group,Dex 20μg/ml group,Dex 40μg/ml group and Dex 80μg/ml group;Each group has 6 parallel samples per hole.After each group of cell culture,we detected the cell proliferation by CCK-8 method,cell apoptosis by flow cytometry,mir-1307 expression by qRT-PCR,cell invasion and cell migration(Transwell)respectively Results Dex inhibits the viability of lung cancer A549 cells in a concentration-and time-dependent manner.Dex can promote the apoptosis of lung cancer A549 cells,and the apoptosis rate can be increased to 22.23%when the concentration of Dex reaches 80μg/ml,the apoptosis rate can rise to 22.23%.Dex inhibits the migration and invasion of lung cancer A549 cells in a concentration-dependent manner.In addition,the relative expression of miR-1307 in A549 cells after Dex treatment decreased significantly comparing to the control group,and the decline was more noteworthy with the increase of Dex concentration.Conclusion Dex can effectively inhibit the proliferation,invasion,metastasis,and apoptosis of humen A549 cells in a dose-dependent manner,and its efficacy may be related to its regulation of miR-1307 expression.

Cervical cancer is a malignant tumor of the female reproductive system, which is closely related to persistent infection with high-risk human papillomavirus (HPV). Locally advanced cervical cancer (LACC) refers to cervical cancer of stage IB3 to IVA [International Federation of Gynecology and Obstetrics (FIGO) 2018 staging], characterized by tumor diameter greater than 4 cm or invasion of adjacent tissues. The standard treatment for LACC is concurrent chemoradiotherapy, with cisplatin as the preferred chemotherapeutic agent. However, there is still a clinical need for further improvement of the overall prognosis of LACC, and exploring effective adjuvant treatment strategies after concurrent chemoradiotherapy to increase the cure rate and quality of life of LACC patients is an important topic in clinical practice. This article reviews the types, indications, effects and existing problems of adjuvant treatment after concurrent chemoradiotherapy for LACC.

Objective To explore the health promotion behaviors among patients with pulmonary tuberculosis(TB),and to analyze its relationship with health locus of control,in order to provide scientific references for improving TB patients'health-promotion behaviors in clinical nursing care.Methods The interpretive sequence mixed method design was utilized.A convenient sampling was used to enroll 300 TB patients from 2 TB specialized tertiary hospitals in Xi'an as research subjects from January to April 2023.General information questionnaire,Health promoting lifestyle profile-Ⅱ,and Multidimensional health locus of control scale were used to collect data,and single-factor analysis and multiple linear regression analysis were conducted.Purposeful sampling was used to select 11 TB patients for a semi-structured interview,and the Colaizzi 7-step method was used to extract themes.Results In the quantitative study,the total score of health promoting behaviors in 294 TB patients was(110.26±15.74).Patients'intemal health locus of control,chance health locus of control,and occupational status significantly influenced their health-promotion behaviors(P＜0.05).In the qualitative study,4 themes were extracted,including awakening self-awareness of health,the desire to establish a normal life,the distress of multiple uncertainties,and the immediate effect of authoritative guidance.The qualitative and quantitative studies complemented each other and further verified the relationship between health promotion behaviors and health locus of control of TB patients.Conclusion The level of health-promotion behaviors in TB patients needs to be further improved.Nurses need to take systematic health education as an opportunity by the catalytic effect of individual health awareness,to improve their internal locus of control,reduce their opportunity control tendency due to multiple uncertainties,with the ultimate purpose of helping TB patients form and maintain health promotion behaviors.

OBJECTIVE: To explore the genetic etiology of a child with D bifunctional protein deficiency (DBPD) born to a consanguineous pedigree. METHODS: A child with DBPD who was admitted to the First Affiliated Hospital of Hainan Medical College on January 6, 2022 due to hypotonia and global developmental delay was selected as the study subject. Clinical data of her pedigree members were collected. Peripheral blood samples of the child, her parents and elder sisters were collected and subjected to whole exome sequencing. Candidate variant was validated by Sanger sequencing and bioinformatic analysis. RESULTS: The child, a 2-year-and-9-month-old female, had featured hypotonia, growth retardation, unstable head lift, and sensorineural deafness. Serum long-chain fatty acids were elevated, and auditory brainstem evoked potentials had failed to elicit V waves in both ears with 90 dBnHL stimulation. Brain MRI revealed thinning of corpus callosum and white matter hypoplasia. The child's parents were secondary cousins. Their elder daughter had a normal phenotype and no clinical symptoms related to DBPD. Elder son had frequent convulsions, hypotonia and feeding difficulties after birth, and had died one and a half month later. Genetic testing revealed that the child had harbored homozygous c.483G>T (p.Gln161His) variants of the HSD17B4 gene, for which both of her parents and elder sisters were carriers. Based on the guidelines from the American College of Medical Genetics and Genomics, the c.483G>T (p.Gln161His) was rated as a pathogenic variant (PM1+PM2_Supporting+PP1+PP3+PP4). CONCLUSION The homozygous c.483G>T (p.Gln161His) variants of the HSD17B4 gene caused by the consanguineous marriage probably underlay the DBPD in this child.
