Objective:
To investigate the trend in incidence and change in age at onset of lung cancer in in Wujiang District, Suzhou City, Jiangsu Province from 2012 to 2021, so as to provide a basis for strengthening targeted prevention and control of lung cancer.
Methods:
Data of lung cancer incidence from 2012 to 2021 were collected through the Wujiang District Tumor Follow-up Registration Information System. The crude incidence, truncated incidence for 35 to 64 years, and cumulative incidence for 0 to 74 years were calculated. Chinese population-standardized incidence, Chinese population-standardized average age at onset, and Chinese population-standardized incidence proportion were calculated using the age structure of the standard population from the Fifth National Population Census in 2000. The trend in incidence of lung cancer from 2012 to 2021 was evaluated using average annual percent change (AAPC). The trend in the Chinese population-standardized average age at onset of lung cancer from 2012 to 2021 was evaluated using a linear regression model.
Results:
From 2012 to 2021, the crude incidence, the Chinese population-standardized incidence and truncated incidence for 35 to 64 years of lung cancer in Wujiang District were 84.57/100 000, 37.28/100 000 and 52.10/100 000, respectively, all showing upward trends (AAPC=2.489%, 2.034% and 4.654%, all P<0.05). The cumulative incidence for 0 to 74 years was 4.48%, showing no significant trend (P>0.05). The Chinese population-standardized incidence was higher in males than in females (48.16/105 vs. 26.81/105). The Chinese population-standardized incidence of lung cancer in females showed an upward trend (AAPC=8.174%, P<0.05), while the trend in males was not statistically significant (P>0.05). The crude incidence of lung cancer showed upward trends in the total population and females aged 0-<45 years (AAPC=18.287% and 25.343%, both P<0.05) and those aged 45-<55 age group (AAPC=8.003% and 17.629%, both P<0.05). The Chinese population-standardized average age at onset of lung cancer in total population and females decreased from 67.58 and 65.48 years in 2012 to 60.15 and 54.88 years in 2021, with an average annual reduction of 0.611 and 0.964 years, respectively (both P<0.05). The Chinese population-standardized incidence proportion showed upward trends for the total population and females under 65 years (AAPC=3.879% and 4.639%, both P<0.05). No statistically significant trends were observed in the Chinese population-standardized average age at onset or incidence proportion in males (both P>0.05).
Conclusions
From 2012 to 2021, the incidence of lung cancer in Wujiang District showed an increasing trend and a trend toward younger onset age. Young and middle-aged females had emerged as a key target population for lung cancer prevention and control.

The aim of this study was to investigate the risk factors for brucellar spondylitis.Electronic medical record data for patients with brucellosis at Yidu Central Hospital in Weifang City were retrospectively collected from January 2018 to April 2024,including general data,clinical characteristics,and laboratory examinations.The patients were divided into a spinal in-volvement group and a no spinal involvement group.The risk factors for brucellar spondylitis were determined through multi-factorial logistic regression model analysis.Of the 124 patients with brucellosis,59 had brucellar spondylitis,and 65 had bru-cellosis alone.There were more patients with age ≥55 years(x2=17.71),time from onset to diagnosis ≥30 days(x2=26.17),and low back pain(x2=52.71)in the spinal involvement group than in the group without spinal involvement,and the difference was statistically significant(all P<0.001);there were more patients with headaches in the group without spinal in-volvement than in the group with spinal involvement,and the difference was statistically significant(x2=8.34,P<0.05).and there were more patients in the spinal involvement group with neutrophil percent(NEU%)(t=2.94),platelet count(PLT)(t=122.00),blood sedimentation rate(ESR)(Z=-6.74),C-reactive protein(CRP)(Z=-5.74),and interleukin-6(IL-6)(Z=-2.08)were higher in the spine-involved group than in the group without spine-involvement,and the differences were all statistically significant(all P<0.05);Lactate dehydrogenase was significantly lower in the spine-involved group(LDH)than the group without spinal involvement(t=-2.04,P<0.042).A multifactorial logistic regression analysis indicated that a du-ration of out-of-hospital symptoms ≥30 days(OR=6.265,95%CI 1.181-33.241),symptoms of low back pain(OR=14.885,95%CI 3.144-70.472),elevated PLT(OR=1.013,95%CI 1.004-1.023),and elevated ESR(OR=1.053,95%CI 1.008-1.100)were risk factors for brucellar spondylitis(all P<0.05).The optimal cut-off values for ROC analysis were PLT>278.5 ×109/L(sensitivity 89.2%,specificity 59.3%)and ESR>16.5 mm/h(sensitivity 69.2%,specificity of 86.4%);using both PLT and ESR for diagnosis yielded an AUROC of 0.891(95%CI 0.831-0.950),a sensitivity of 86.2%,and a specificity of 84.7%.When patients with brucellosis present with symptoms of low back pain,a time from onset to diagnosis of ≥30 days,and markedly elevated ESR and PLT,lumbar magnetic resonance examination is recommended to rule out brucellar spondylitis,to enable early diagnosis and timely treatment,improve patient prognosis,shorten illness duration,and improve patient quality of life.

As the world's second largest vector of pathogens,ticks can spread a variety of pathogens by sucking the host's blood.Ticks not only threaten human life and health,but also cause great economic losses in animal husbandry.Artificial breeding of ticks can provide a stable environment for the growth and reproduction of ticks,thereby generating sufficient exper-imental materials for understanding ticks'biological characteristics,studying tick-borne pathogens,and developing anti-tick drugs and vaccines.Current methods of breeding ticks in the laboratory can be roughly divided into two categories:breeding methods using host animals or artificial membranes.The selection of breeding method must be comprehensively considered,ac-cording to tick types,blood-sucking habits,living environments,and other aspects.The development processes of the two methods,and their respective advantages and disadvantages,are described and discussed,to assist laboratories in artificial breeding of ticks.

The construction of the National Medical Center and the National Regional Medical Center in the Chengdu-Chongqing Economic Circle (referred to as the dual medical center construction) faces the challenges of insufficient integration of industry, academia, research, and medicine, as well as limited joint development and sharing of high-quality resources. It is urgent to promote the integration and coordinated development of regional education and technology talent resources through the integration of higher medical education, and to enhance the "four chains" synergy with the integration of industry and education as the core, thereby promoting the dual medical center construction. This study investigated and summarized the key issues in the dual medical center construction and the integration of higher medical education in the Chengdu-Chongqing Economic Circle. Based on the theoretical framework of four chain coordination (industry chain-talent chain-education chain-city chain), this study clarified the mechanisms by which integrated higher medical education can promote dual medical center construction. The study found that the integration of higher medical education can effectively promote the optimization of resources for dual medical center construction by constructing a collaborative mechanism of "industry education integration-joint talent cultivation-coordinated discipline construction-intercity cooperation". Based on the strengths in higher education resources in Chengdu and Chongqing, a five-dimension collaborative path was proposed: integrated development; technological leadership; talent oriented; government guidance; and market assistance. The research conclusion not only enhances the understanding of the integration of higher medical education, but also provides theoretical basis and practical reference for the dual medical center construction in the Chengdu-Chongqing Economic Circle. The proposed coordinated development also has reference value for the construction of medical centers in urban agglomerations such as the Beijing-Tianjin-Hebei Urban Agglomeration and the Yangtze River Delta.

With the continuous increase in global obesity prevalence,the impact of obesity on reproduc-tive physiology has garnered widespread societal attention.As a metabolic disorder,obesity is typically accompanied by multiple abnormal physiological phenomena,such as excessive adipose accumulation and exacerbated inflammatory responses,which severely compromise the reproductive health of humans and animals.Reproductive damage induced by obesity involves a series of complex biochemical reactions and in vivo metabolic pathways,manifesting as impaired male sperm quality and female fertility.To better un-derstand the relationship between obesity and reproductive physiology,this review summarizes the repro-ductive injuries caused by obesity and their underlying mechanisms.In the obese state,conditions such as oxidative stress,insulin resistance,and hyperinsulinemia are induced,with adipokines(leptin,adi-ponectin,resistin,etc.)and inflammatory factors(TNF-α,IL-6,IL-1β,etc.)interacting synergisti-cally to affect the reproductive system.Oxidative stress activates the MAPK and NF-κB pathways,inter-fering with insulin signaling,while chronic inflammation leads to adipocyte secretory disorders and dis-rupts the hypothalamic-pituitary-gonadal regulatory axis.Studies have shown that obese males exhibit sig-nificantly decreased testosterone levels and impaired sperm quality,whereas obese females suffer from re-productive hormone imbalance,ovulation disorders,and polycystic ovary syndrome.This review discus-ses how obesity-induced metabolic disorders lead to impaired reproductive physiology in both males and females,along with the underlying mechanisms,providing a theoretical basis for the prevention and treat-ment of obesity-related reproductive disorders in the future.

Objective To compare the accuracy differences of three-dimensional reconstruction of zygomatic-maxillary complex using cone beam computed tomography(CBCT)and multi-slice spiral computed tomography(MSCT)in the parameters related to zygomatic implantation.Methods Five adult skull specimens(10 zygomatic-maxillary complexes in total)were selected.According to the clinical application characteristics of zygomatic implantation,the parameter location for each skull specimen was conducted,and then CBCT and MSCT were used for scanning and three-dimensional reconstruction.Four parameters were measured on both skull specimens and reconstructed models:the thickness of the maxillary zygomatic process at the intersection of the zygomatic implant path and zygomaticomaxil-lary suture(LB-B1),the thickness of the zygomatic bone at the intersection of the zygomatic implant path and the midpoint of the zygomatic bone surface(LC-C1),the width of the alveolar ridge between the second premolar and the first molar(LAR),and the buccolingual width of the first molar(LM).The specimen group was measured by electronic vernier caliper,and the CBCT group and MSCT group were measured based on CBCT and MSCT.The absolute and relative errors of these four parameters were calculated,and the accuracy of the CBCT and MSCT three-dimensional reconstruction models were analyzed.Results All parameters demonstrated excellent measurement reliability and repeatability,with intra-class correlation coefficient(ICC)≥0.90.The measurement results of each parameter in the CBCT group and the MSCT group showed statistically significant differences compared with those in the specimen group(P<0.05).The measurement result of LM in the CBCT group was smaller than that in the MSCT group,and the difference was statistically significant(P<0.05).However,the measurement results of LB-B1,LC-C1 and LAR in the CBCT group showed no statistically significant difference compared with those in the MSCT group(P>0.05).The mean absolute error and relative error of the LM measurement results to the specimen group in the CBCT group were both smaller than those in the MSCT group,and the differences were statistically significant(P<0.05).There was no statistically significant difference in the mean absolute error or relative error of the LB-B1,LC-C1 and LAR measurement results to the specimen group between the CBCT group and the MSCT group(P>0.05).Conclusion CBCT and MSCT demonstrat comparable accuracy in three-dimensional reconstruction of the zygomatic-maxillary complex.However,CBCT exhibits superior accuracy for fine structures such as dental tissues,which is recommended as the primary choice for imaging data acquisition in zygomatic implantation.
