Objective: To analyze the disease burden and trends of oral diseases among China’s elderly population (1990-2021) and provide evidence for developing targeted intervention strategies Methods : Using data from the Global Burden of Disease (GBD) 2021 study, we extracted prevalence, incidence, and disability-adjusted life years (DALYs) for oral conditions (permanent dental caries, edentulism, periodontal diseases, and other oral disorders) in individuals aged ≥60 years in China. Due to data limitations, other oral diseases only included DALYs and prevalence. Age-standardized rates (ASR)—including age-standardized prevalence rate (ASPR), age-standardized incidence rate (ASIR), and age-standardized DALYs rate (ASDR)--were calculated. Trends were assessed via Joinpoint regression using average annual percentage change (AAPC), stratified by sex and age groups (60-64, 65-69, 70-74, 75-79, 80-84, 85-89, 90-94, 95+ years). Results: From 1990 to 2021, China’s elderly population exhibited distinct trends in oral disease burden. Overall oral diseases showed declining ASDR and ASPR, yet ASIR slightly increased. Permanent dental caries demonstrated significant rises across ASDR, ASIR, and ASPR. Edentulism showed declining ASDR and ASPR alongside stable ASIR. 95+ age group saw rising rates. Periodontal diseases remained largely stable in ASDR and ASPR but experienced a slight ASIR decline. Other oral disorders showed mild ASDR decline and stable ASPR. Notably, sex and age disparities persisted. Women consistently bore higher burdens for overall oral diseases, caries, edentulism, and other oral diseases but lower periodontal disease rates compared to men. 85-89, 90-95, 95+ age group faced rising DALYs and prevalence for overall oral diseases, while all other age groups demonstrated declining trends in both DALYs and prevalence; for permanent caries, the 60-64 age group showed the largest increases in DALY rate, incidence, and prevalence; edentulism demonstrated the most pronounced and sustained rises in DALY rate and prevalence in the 95+ group, while declining most rapidly in the 60-64 age group; for periodontal disease, both DALY rates and prevalence declined in the 90-94 and 95+ age groups, but increased across all measures (DALY rate, incidence, and prevalence) in the 70-74 and 75-79 age group; other oral conditions exhibited relatively stable burden distributions or minor changes, with no significant age-specific shifting trends observed. Conclusion From 1990 to 2021, China’s elderly oral disease burden declined overall, but caries surged, edentulism improved, periodontal diseases stabilized, and other oral diseases slightly declined. Prioritizing older women and the adults aged 85+ is critical to addressing evolving oral health needs.

Objective: To investigate the trend in disease burden of injuries among children and adolescents in China from 1990 to 2021, so as to provide a basis for formulating prevention and control strategies and reducing this disease burden. Methods: Data on mortality, disability-adjusted life years (DALY) rate, incidence, and prevalence of injuries among children and adolescents aged <20 years in China from 1990 to 2021 were collected from the Global Burden of Disease (GBD) 2021 database. All rates were standardized using the GBD 2021 world standard population. The trend in incidence of disease burden of injuries among children and adolescents across differents genders and ages from 1990 to 2021 was evaluated using average annual percent change (AAPC). Results: From 1990 to 2021, the standardized mortality (AAPC=-5.435%), standardized DALY rate (AAPC=-5.311%), standardized incidence (AAPC=-0.466%), and standardized prevalence (AAPC=-0.810%) of injuries among children and adolescents in China showed downward trends (all P<0.05). Among these, the standardized mortality of animal contact (AAPC=-9.138%) and the standardized DALY rate of medical side effects (AAPC=-8.389%) decreased at a relatively fast pace, while the standardized incidence of falls (AAPC=0.083%) and the standardized prevalence of exposure to natural forces (AAPC=2.656%) showed upward trends (all P<0.05). The standardized mortality, standardized DALY rate, standardized incidence and standardized prevalence of injuries were higher in males than in females. The trend in males showed a downward trend (all P<0.05), consistent with the total population. The crude incidence of injuries in the group aged 15-<20 years showed an upward trend (AAPC=0.391%, P<0.05), while the trend in the group aged 10-<15 years was not statistically significant (P>0.05). The crude incidence of injuries in the groups aged 5-<10 years and <5 years showed downward trends (AAPC=-0.488% and -2.275%, both P<0.05). In 2021, the <5 years age group had the highest crude mortality and crude DALY rate of injuries, at 13.94/100 000 and 1 257.26/100 000, respectively. The 15-<20 years age group exhibited the highest crude incidence and crude prevalence, at 4 874.05/100 000and 4 050.35/100 000, respectively. Drowning and falls were major components of the disease burden across all age groups. Conclusions From 1990 to 2021, the disease burden of injuries among children and adolescents in China showed an overall downward trend. The disease burden was consistently higher in males than in females. Children aged <5 years face a high risk of fatality and disability, while adolescents aged 15-<20 years experience a high incidence and frequency of injuries. Drowning and falls were key priorities for prevention and control.

ObjectiveTo evaluate the implementation effect of the basic public health service project in Jiangbei District of Chongqing， so as to provide a basis for further improving the service content and social/economic benefits of the project. MethodsThe evaluation was conducted according to the “National Basic Public Health Service Regulations”， “National Basic Public Health Service Project Performance Evaluation Guidance Plan” and the assessment indicators， indicator requirements and weights of each project. The items were evaluated one by one， and each item was calculated and compared to obtain the trends in the three years from 2018 to 2020. ResultsThe evaluation results showed that the twelve contents of the basic public health service projects in Jiangbei District either met or exceeded the national requirements. The overall effect increased year by year， from 71.73 to 78.74 points. Eight of the twelve service contents have improved year by year， among which the report and processing of information related to infectious diseases and public health emergencies reached 100%， and the vaccination rate of “eight vaccines” reached 97%. Maternal and children （0-6 years old） health care increased significantly， rising by 39.89% and 36.62% respectively. Chronic disease health management was unsatisfactory. ConclusionThe effects of implementation of the basic public health service project is significant， and the service quality has improved year by year. The service content and assessment indicators are still imperfect and is worth of further research.

Objective:To establish an animal model of chronic systemic inflammation with long-term high expression of circulating IL-6 by introducing exogenous IL-6 gene transfer vector.Methods:Recombinant murine IL-6-encoding adeno-associated virus (AAV-IL-6) was constructed. Twenty-one 24-week-old male C57BL/6J mice were randomly divided into three groups with seven in each group: AAV-IL-6 group, vector control (AAV-ctrl) group and blank control group. At 0, 8 and 16 weeks of intervention, the mice in the three groups were injected with AAV-IL-6 (100 μl 0.5×10 10 vp/ml), unloaded AAV (100 μl 0.5×10 10 vp/ml) and the same volume of saline in the tail vein, respectively. IL-6 levels in mouse serum were measured by ELISA. The general condition of mice was observed and blood routine tests were performed. Changes in blood biochemical parameters and C-reactive protein (CRP) levels were detected. At the end of 24-week intervention, the mice were sacrificed and the myocardium, liver, spleen, quadriceps femoris, knee joint and middle femur were taken for HE staining. Results:At 4, 8, 16 and 24 weeks after intervention, serum IL-6 levels were (75.41-169.28) pg/ml in the AAV-IL-6 group, while in the two control groups, the levels were below the lower limit of detection (7.8 pg/ml). At 24 weeks after intervention, the body weight of mice in the AAV-IL-6 group was significantly lower than that of mice in the two control groups; the neutrophil counts and CRP level in the AAV-IL-6 group were higher than those in the two control groups, while the levels of albumin, creatinine, triglyceride and cholesterol were lower than those in the two control groups. There were no differences in the aforementioned parameters between the two control groups. Compared with the blank control group, both AAV-IL-6 and AAV-ctrl groups showed increased lymphocyte counts. All mice had normal liver and kidney functions at the end of intervention. Histopathological findings indicated that the mice in the AAV-IL-6 group had focal infiltration of lymphocytes in the central venous area of the liver and around the myocardial and the skeletal muscle fibers, diffuse infiltration of multinucleated giant cells in the spleen, atrophic skeletal muscle, disorganized growth plate, reduced chondrocyte hypertrophic zone, thinner bone cortex and trabecular, and reduced osteoid. There were no histopathological changes in mice of the two control groups.Conclusions:Repeated tail vein injection of AAV-IL-6 could achieve long-term high expression of circulating IL-6 in mice, which manifested the phenotype of chronic systemic inflammation in preliminary detection and provided a safe, effective and simply accessible animal model for related studies.

All 6 patients had good prognosis after antibiotic therapy.Conclusion:The clinical manifestations of neurological brucellosis are diverse; the combined application of cerebrospinal fluid culture, cerebrospinal fluid brucella agglutination test, and next-generation sequencing is of great value in the diagnosis of neurobrucellosis.

Objective:To explore the difference of high-risk factors between early-onset and late-onset pre-eclampsia, and to further understand high-risk factors of pre-eclampsia.Methods:Clinical data of pre-eclampsia pregnant women in 160 medical institutions in China in 2018 were retrospectively analyzed, including 8 031 cases of early-onset pre-eclampsia and 12 969 cases of late-onset pre-eclampsia. The proportion of high-risk factors, different body mass index (BMI) and age stratification between early-onset group and late-onset group were compared.Results:(1) Univariate analysis of high-risk factors: the proportions of high-risk factors in early-onset group and late-onset group were compared, and the differences were statistically significant (all P<0.05). Among them, the proportions of primipara and multiple pregnancy in early-onset group were lower than those in late-onset group, while the proportions of pregnant women with advanced age, irregular antenatal examination, obesity, family history of hypertension, pre-eclampsia, diabetes, kidney diseases, immune system diseases and assisted reproductive technology were higher than those in late-onset group. (2) Hierarchical analysis of BMI: the proportion of pregnant women with BMI≥24 kg/m 2 in early-onset group [48.2% (2 828/5 872) vs 45.5% (4 177/9 181), respectively; P=0.001] and the proportion of pregnant women with BMI ≥28 kg/m 2 in early-onset group [19.5% (1 143/5 872) vs 18.0% (1 656/9 181), respectively; P=0.028] were significantly higher than those in late-onset group. (3) Age stratification analysis: the proportion of pregnant women aged 35-39 years in the early-onset group [21.8% (1 748/8 023) vs 17.5% (2 110/12 068), respectively; P<0.01], the proportion of pregnant women 40-44 years old [6.8% (544/8 023) vs 5.4% (648/12 068), respectively; P<0.01], and the proportion of pregnant women ≥45 years old [0.7% (58/8 023) vs 0.5% (57/12 068), respectively; P=0.021] were significantly higher than those in the late-onset group. (4) Multivariate analysis: advanced age (≥35 years old), multiple pregnancy, irregular antenatal examination or transfer from other hospitals, family history of hypertension (including paternal, maternal and parental lines), previous history of pre-eclampsia, kidney diseases, immune system diseases (systemic lupus erythematosus, antiphospholipid antibody syndrome) and assisted reproductive technology pregnancy were the risk factors affecting the severity of pre-eclampsia (all P<0.05). Conclusion:Pregnant women with high risk factors such as age ≥35 years old, BMI ≥24 kg/m 2 before pregnancy, family history of hypertension, history of pre-eclampsia, chronic kidney diseases, immune diseases (mainly including systemic lupus erythematosus and antiphospholipid syndrome) and assisted reproductive technology are more likely to have early-onset pre-eclampsia.

Objective To observe the clinical effect of Yanshu compound radix sophore injection combined with radiotherapy in treatment of patients with bone metastases from lung cancer. Methods A total of 116 patients with bone metastases from lung cancer admitted to the Department of Radiation Oncology of Gansu Provincial Cancer Hospital from January 2014 to December 2018 were selected. The 58 patients were treated by using three-dimensional conformal radiotherapy (3D-CRT), zoledronic acid and oxycodone sustained-release tablets (control group); the others 58 patients were treated radix sphore injection on basis of control group (integrated Chinese and western medicine). The two groups were treated continuously for 10 days as 1 course of treatment, taking a rest for one week in the middle, then they took the second course of treatment; after the end of 2 courses, the therapeutic effects were evaluated in the two groups. The pain grading, Karnofsky functional status (KPS) score and myelosuppression were observed before and after treatment in two groups, respectively. Results The proportions of patients with painless and mild pain after treatment in the integrated Chinese and western medicine group were significantly lower than those in control group [painless: 22.41% (13/58) vs. 39.66% (23/58), mild pain: 10.35% (6/58) vs. 46.55% (27/58)], while the proportions of patients with moderate pain and severe pain in the integrated Chinese and western medicine group were significantly higher than those of the control group [moderate pain: 53.45(31/58) vs. 12.07% (7/58), severe pain: 13.79% (8/58) vs 1.72% (1/58), both P < 0.05]. After treatment, the proportion of patients with improved KPS score in integrated Chinese and western medicine group was significantly higher than that in control group [55.17% (32/58) vs. 36.21% (21/58), P < 0.05], and the proportion of patients with stable and decreased KPS score were less than that of control group [stable KPS score:18.97%(11/58) vs. 27.59%(16/58), decreased KPS score:25.86% (15/58) vs. 36.21% (21/58)]. The proportions of patients with blood cell count (WBC), hemoglobin (Hb) and platelet count (PLT) showing no myelosuppression (at the zero degree) after treatment in integrated Chinese and western medicine group were obviously higher than those in control group [WBC: 77.59% (45/58) vs. 36.21% (21/58), Hb: 77.59% (45/58) vs. 70.69% (41/58), PLT: 58.62% (34/58) vs. 32.76% (19/58), all P < 0.05]. Conclusion Yanshu compound radix sphore injection combined with radiotherapy can reudce bone metastasis pain, reduce bone marrow suppression and improve quality of life in patients with advanced lung cancer and bone metastasis.

Objective To analyze the trend and epidemiological features of human brucellosis from 2010 to 2016 in Weinan,Shaanxi Province,and to provide scientific data for effective control of human brucellosis.Methods The data were obtained from the China Disease Surveillance Information Management System and the brucellosis monitoring and epidemic survey of Weinan City from 2010 to 2016.The "three distribution" of brucellosis,the positive rate of serological test of the key group and the infecting route of the epidemic were analyzed using descriptive epidemiology method.Results A total of 1 624 brucellosis cases were reported in Weinan City from 2010 to 2016 and none death case occurred.The morbidity rose from 1.96/100 000 in 2010 to 11.16/100 000 in 2014.The morbidity fallen from 5.46/100 000 in 2015 to 3.33/100 000 in 2016.The reported cases distributed in 10 counties of Weinan and mainly concentrated in Dali County (682 cases),Chengcheng County (269 cases) and Pucheng County (225 cases),accounting for 72.41％ (1 176/1 624).There were brucellosis occurring in all months of the year.The age group distributed mainly from 40 to 64 years old which accounted for 63.67％ (1 034/1 624) of the total reported cases.The peasants accounted for 91.75％ (1 490/1 624) in all cases.Men were significantly higher than women and the morbidity ratio of male to female was 3.28 ∶ 1.00 (1 245 ∶ 379).A total of 15 126 key occupational persons were tested and the positive rate of serology was 2.21％ (335/15 126) annually.The feeding and delivery process were the main ways of infection.Conclusions The brucellosis epidemic in Weinan shows a trend from rise to decline.The middle-aged male peasants account for major population in all cases and the ways of infection are diversified.

Objective To investigate the correlation between the incidence of thyroid carcinoma and TSH, and to provide evidence for clinical application.MethodsSelect 450 cases of patients with thyroid from August 2014 to August 2016 in our hospital as the object of study in this group, the analysis of gender and age of patients, lymph nodes, tumor, laboratory examination results, to explore the relationship between TSH levels and thyroid cancer.ResultsThyroid patients with TSH was significantly higher than that in benign tumor group (P<0.05);the level of TSH and patients with lesion diameter, tumor stage, lymph node metastasis and capsule invasion was significantly correlated (P<0.05), but the level of TSH and age, gender, tumor number, vascular invasion and no significant correlation;TSH the level of thyroid cancer patients were significantly increased (P<0.05).ConclusionThe level of TSH in serum is closely related to the occurrence and development of thyroid cancer, and is closely related to lymph node metastasis and tumor stage, and the higher TSH level can increase the risk of thyroid cancer.

Objective To investigate the molecular genetic causes and their characteristics of deafness from patients with nonsyndromic hearing loss in Gansu province.Methods Peripheral blood samples were obtained from a total of 375 patients with nonsyndromic hearing loss to extract genomic DNA.Three genes of GJB2, mitochondrial DNA 12SrRNA, and SLC26A4 were screened for mutations in our study cohort using SNPscan technology.Results Among 375 patients, 23 patients were found to carry the homoplasmic mtDNA12SrRNA A1555G mutation, and 2 patients were detected to carry the homoplasmic mtDNA12SrRNA C1494T mutation.Forty-two cases(11.2%) were caused by GJB2 mutations, including 31cases(8.3%) of homozygous mutations, 11 patients(2.9%) of compound heterozygous mutations, and 25 cases(6.7%) of single homozygous mutations.c.235delC was the most prevalent GJB2 mutation with the allele frequency of 8.8%.Twenty-nine cases (7.7%) were caused by SLC26A4mutations, including 17cases(4.5%) of homozygous mutations, 12 patients(3.2%) of compound heterozygous mutations, and 16 cases(4.3%) of single homozygous mutations.c.919-2A>G and c.2168A>G were the most common SLC26A4 mutation, the allele frequencies were 5.2% and 2.0%, respectively.Conclusion A high incidence of mtDNA12SrRNAA1555G mutation is found in nonsyndromic hearing loss patients from Gansu province, while the incidence of GJB2 and SLC26A4 mutations is similar to the level of the overall Chinese deaf population.These findings demonstrate that a total of 25.6% of deaf patients have inherited hearing impairment caused by GJB2, SLC26A4, and mitochondrialDNA12SrRNA mutations.As a result 36% patients and family member can acquire effective genetic counseling.
