Objective:To analyze the surveillance results of brucellosis in Shanxi Province, to gain a understanding of the epidemic characteristics and changing trend of brucellosis in Shanxi Province, and to provide scientific basis for formulating prevention and control strategies and measures for brucellosis.Methods:The surveillance data of brucellosis in Shanxi Province from Infectious Disease Reporting Information Management System of China Disease Prevention and Control Information System, and the active surveillance results of 5 national brucellosis surveillance sites from 2018 to 2023 were collected for descriptive analysis.Results:From 2018 to 2023, a total of 24 041 cases of human brucellosis were reported in Shanxi Province, with the number of cases increased from 2 800 in 2018 to 5 131 in 2023. The annual reported incidence was 11.22/100 000, ranging from 7.56/100 000 to 14.74/100 000, showing an overall upward trend (χ 2trend = 1 377.43, P < 0.001). The epidemic had affected all counties (cities and districts) in the province, mainly concentrated in Linfen City, Jinzhong City, Datong City, and Shuozhou City, with a total of 13 489 cases of human brucellosis reported, accounting for 56.11%. The population distribution was mainly composed of individuals aged 40 - 69 (17 682 cases), males (18 513 cases), farmers (20 295 cases), and household and unemployed individuals (1 017 cases). The onset of the disease showed obvious seasonality, with the peak time from March to August, accounting for 66.39% (15 961/24 041). A total of 14 130 occupational individuals were investigated at the surveillance sites, and 11 141 underwent serological tests, with a positive rate of 5.25% (585/11 141), including 299 new cases. The positive rate of serological tests was relatively high in Qinyuan County, at 8.51% (241/2 832). Etiological culture was conducted on 338 human blood samples, and 43 strains of Brucella were isolated, with a detection rate of 12.72%. All strains were Brucella melitensis, including 42 strains of Brucella melitensis biovar 3. Conclusions:The overall trend of human brucellosis epidemic in Shanxi Province from 2018 to 2023 is on the rise, and it is still at a high level. It is suggested to continue strengthening monitoring, study the epidemic situation in a timely manner, take comprehensive prevention and control measures, and effectively control the spread of brucellosis.

Objective To discuss the effect of different particle activities and tumor shrinkage speed on the dosimetric parameters of the target area at the same prescription dose after 125I particle implantation.Methods A 6cm-sized cube tumor model was outlined by using a computerized three-dimensional treatment planning system(3D-TPS)with a prescription dose(PD)of 100 Gy,and 125I particle activities of 0.4 mCi and 0.8 mCi were selected.Assuming that the tumor shrinks centripetally after seed implantation and that the 125I particles were uniformly and centripetally concentrated without shedding or wandering,the tumor volume shrank at different rates every month after implantation(0,5％,10％,15％,20％,25％,30％,35％,40％,45％and 50％),according to the different activities of 125I particles,the experiments were divided into A1-K1 group(0.4 mCi)and A2-K2 group(0.8 mCi).Based on the 125I particle decay law,the validation program(using TPS simulation of the A1-K1 group and A2-K2 group at postoperative 1,2,3,4,5 and 6 months)obtained the dose received by 90％of the target volume(D90)in the two groups with different 125I particle activities at different postoperative time points,the percentages of the target volume covered by the 100％,150％and 90％prescription dose(V100,V150,V90),and the mean dose(Dmean).By comparing the differences in D90,V100,V150,V90 and Dmean after tumor implantation of 125I particles with different activities,the dosimetric impact of the tumor target area shrinking at a rate of 0～50％after implantation of 125I particles with different activities into tumor tissues was analyzed.Results When the monthly shrinkage rate of the tumor target area was≤30％,there was no obvious difference in D90 between the 0.4 mCi group and 0.8 mCi group in 1～6 months after surgery.When the monthly shrinkage rate of the tumor target area was＞30％,the D90 of 0.8 mCi group was higher than that of 0.4 mCi group;when the monthly shrinkage rate of the tumor target area was＜25％,the V90 of 0.4 mCi group was higher than that of 0.8 mCi group,and the changes of V90 of the two groups tended to be the same in the 5th～6th month after surgery.When the monthly shrinkage rate of the tumor target area was ≥30％,the V90 of 0.8 mCi group was higher than that of 0.4 mCi group,and with the increasing of shrinkage rate,the difference between the two groups become more and more significant,the results of V100 were consistent with those of V90.When the monthly shrinkage rate of tumor target area＜35％,V150 of 0.4 mCi group was higher than that of 0.8 mCi group,when the monthly shrinkage rate of tumor target area ≥35％,V150 of 0.8 mCi group was higher than that of 0.4 mCi group,and with the increasing of shrinkage rate,the difference between the two groups become more and more prominent.When the monthly shrinkage rate of tumor target area＜25％,Dmean of 0.4 mCi group was higher than that of 0.8 mCi group,when the monthly shrinkage rate of tumor target area ≥25％,Dmean of 0.8 mCi group was higher than that of 0.4 mCi group,and with the increasing of shrinkage rate,the difference between the two groups become more and more obvious.Conclusion With the same prescription dose,when the tumor target area shrinks at a rate of＜30％per month,the activity of 125I particles has little effect on D90,and all V90,V100,V150 and Dmean in the low activity group are higher than those in the high activity group,meanwhile the homogeneity of the target area is relatively good;when the monthly shrinkage rate of tumor target area ≥35％,all D90,V90,V100,V150 and Dmean in the high activity group are higher than those in the low activity group,and the duration of the presence of high-dose area is long.This difference becomes more obvious with the increasing of the monthly shrinkage rate of the target area.

Objective To investigate the epidemiological characteristics and influencing factors of Femoral Artery Compression-Related Skin Complications Around the Puncture Site(FACR-SCAPS)in patients with primary hepatocellular carcinoma(HCC)undergoing transarterial chemoembolization(TACE).Methods A multicenter cross-sectional study was conducted using convenience sampling.A total of 1 573 HCC patients who underwent TACE between April 2023 and October 2024 were recruited from interventional radiology departments,oncology units,and specialized centers across 10 hospitals in Beijing,Tianjin,Shandong,Hebei,Qinghai,and Inner Mongolia.Descriptive statistics,univariate analysis,and multivariate logistic regression were used to explore the epidemiological characteristics and influencing factors of FACR-SCAPS in this population.Results Among the 1 573 primary HCC patients undergoing TACE interventional therapy,FACR-SCAPS occurred in 28.99％(456/1 573),with a total of 476 complication instances recorded(30.26 per 100 patients).Patients with a single complication accounted for 96.93％,whereas those with multiple complications constituted 3.07％.The most prevalent types of complications were skin erythema,skin ecchymosis,and hard lumps formation,collectively accounting for 96.49％of all complications.Hematoma,blisters,and rupture complications collectively accounted for only 4.61％.Logistic regression analysis revealed that peak diastolic blood pressure during compression(OR=1.024,95％CI:1.013-1.035,P＜0.001),use of rotary compression hemostasis devices(OR=3.220,95％CI:2.120-4.891,P＜0.001),elevated PT-INR(OR=19.630,95％CI:6.039-63.810,P＜0.001),and anticoagulant use within the last three months(OR=1.909,95％CI:1.064-3.427,P=0.030)were significant influencing factors associated with FACR-SCAPS post-TACE.Conclusion FACR-SCAPS is commonly seen among primary HCC patients after TACE,its risk factors include peak diastolic blood pressure during compression,use of rotary compression devices,elevated PT-INR,and recent anticoagulant use.

Objective:To evaluate the role of nemo-like kinase (NLK) in lipopolysaccharide (LPS)-induced inflammatory responses of mouse bone marrow-derived macrophages (BMDMs) and the relationship with glycolysis.Methods:BMDMs were extracted from the wild type (WT) and NLK knockout (NLK -/-) C57BL/6 mice of either sex, aged 6-8 weeks, weighing 20-25 g, were used in this study. After induction, differentiation, maturation and purity identification, BMDMs were divided into phosphate buffer solution (PBS) control group (WT+ PBS group, NLK -/-+ PBS group, n=18) and LPS group (WT+ LPS group, NLK -/-+ LPS group, n=18) by a random number table method. LPS at a final concentration of 1 μg/ml was added to stimulate mature BMDMs for 6 h in LPS group, while the equal volume of PBS was given instead in PBS group. The cell viability was measured by Calcein/PI staining, and the expression of cellular NLK, inflammatory factors (tumor necrosis factor-alpha [TNF-α], interleukin-1 beta [IL-1β] and IL-6) and key glycolytic enzymes (hexokinase 2 [HK2], pyruvate kinase M2 (PKM2) and lactate dehydrogenase A [LDHA])mRNA was detected by real-time fluorescent quantitative polymerase chain reaction. Western blot was used to detect the expression of NLK, HK2, PKM2 and LDHA. The concentrations of TNF-α, IL-1β and IL-6 in the supernatant were determined by enzyme-linked immunosorbent assay. Glucose uptake and lactic acid production were measured by hexokinase method and colorimetric method respectively. Results:Compared with WT-type BMDMs, the expression of NLK protein and mRNA in NLK -/--type BMDMs was significantly down-regulated ( P<0.05). Compared with WT+ PBS group, the BMDM viability was significantly decreased, the expression of TNF-α, IL-1β and IL-6 was up-regulated, the concentrations of TNF-α, IL-1β and IL-6 in the supernatant were increased, the expression of NLK, HK2, PKM2 and LDHA protein and mRNA was up-regulated, and the glucose uptake and lactic acid production were increased in WT+ LPS group ( P<0.05). Compared with WT+ LPS group, the BMDM viability was significantly increased, the expression of TNF-α, IL-1β and IL-6 was down-regulated, the concentrations of TNF-α, IL-1β and IL-6 in the supernatant were decreased, the expression of NLK, HK2, PKM2 and LDHA protein and mRNA was down-regulated, and the glucose uptake and lactic acid production were decreased in NLK -/-+ LPS group ( P<0.05). Conclusions:NLK may enhance LPS-induced inflammatory responses of BMDMs by promoting glycolysis in BMDMs of mice.

Objective:To explore the prevalence and risk factors of insomnia in Chinese Air Force servicemen deployed to highland areas.Methods:A total of 718 Air Force servicemen deployed to Qinghai-Tibetan plateau were recruited at May 2024.Sleep quality was assessed with the Pittsburgh Sleep Quality Index.Social-demograph-ic,military service,and psychological characteristics were measured with a self-administered general question-naire.Bivariable and multivariable logistic regressions were performed to identify independent risk factors.Missing data were handled by the multiple imputation.Results:The average sleep duration was(6.9±1.2)h and the aver-age PSQI score was(5.9±4.1).Totally 53.8％of participants experienced clinically significant insomnia.The multivariable analysis revealed that age≥35(aOR=4.07,95％CI=1.11-17.76),stressful event(aOR=3.27,95％CI=2.00-5.49),dysfunctional sleep beliefs and attitudes(aOR=2.59,95％CI=1.75-3.85),and caffeine product usage(aOR=1.69,95％CI=1.17-2.43)were risk factors for insomnia,while Tibetan-indigenous ethnic(aOR=0.44,95％CI=0.20-0.91),higher perceived social support(aOR=0.96,95％CI=0.96-0.99),and positive coping style(aOR=0.96,95％CI=0.93-0.99)were protective factors.Conclusion:Air force service-men deployed to highland areas have sufficient sleep time,but reduced sleep quality.Age,exposed to stress event during deployment,dysfunctional sleep beliefs and attitudes,and caffeine product usage are risk factors for insomni-a,while Tibetan-indigenous ethnic,higher perceived social support and positive coping style act as protective fac-tors.

Lens injury is an important etiological factor in the reduction of visual function following ocular trauma.Currently, there are no clear standards for the classification of lens injury, and comprehensive diagnostic tools are lacking.This deficiency leads to numerous controversies and challenges in critical areas, such as diagnosis and preoperative evalution, timing of surgery, surgical strategy, and assessment of postoperative prognosis.Tomographic imaging technology, such as computed tomography, magnetic resonance imaging, optical coherence tomography, has introduced a new dimension to the evaluation of lens injury, which is crucial for assessing the transparency, texture, location, morphology, and integrity of the lens, as well as the zonules and nearby intraocular structures.However, the use of tomographic imaging technology is somewhat limited due to the limitations of relying on a single method.With the ongoing advancement of imaging technologies and the rapid development of big data and artificial intelligence, tomographic imaging will become an increasingly essential tool in the future management of lens injury.Our expert group reviewed the epidemiological characteristics and classification of lens injury and the major challenges currently faced in the diagnosis and treatment of lens injury, and provided expert recommendations mainly focusing on the application, shortcomings and limitations of current tomographic imaging technology in the diagnosis and treatment of lens injury, and future development directions.

Objective:To investigate the surgical technique and initial outcomes of distal derotational femoral osteotomy (DDFO) combined with knee extension device reconstruction in adolescents with habitual patellar dislocation and severe lower limb torsional deformity.Methods:A retrospective study was conducted on 10 adolescent patients (12 knees) treated at Beijing Jishuitan Hospital and its Guizhou branch from June 2016 to June 2022. There were 6 males and 4 females with an average age of 12.0±1.5 years (range: 10.0-14.5 years) Surgical treatment included DDFO and knee extension device reconstruction (lateral retinacular release, medial retinacular plication, Roux-Goldthwait distal realignment, and MPFL reconstruction). Clinical outcomes were assessed using Lysholm scores, incidence of redislocation and complications, and imaging parameters (lateral patellofemoral angle, Insall-Salvati index, TT-TG distance, and femoral anteversion angle) preoperatively and at 1 year postoperatively.Results:All 12 knees were successfully operated on, with an average surgery time of 2.0±0.5 h (range 1.0-2.5 h), intraoperative blood loss of 47.1±17.1 ml (range 20-80 ml), and follow-up time of 46.2±18.7 months (range 24-72 months). The Lysholm knee score improved from 58.25±8.80 preoperatively to 89.17±5.32 at final follow-up ( t=-9.096, P<0.001) with significant difference. The lateral patellofemoral angle improved from -64.92±4.68 preoperatively to 6.08±2.27 at final follow-up ( t=39.178, P<0.001) with significant difference. The femoral anteversion angle decreased from 34.08±3.06 preoperatively to 14.50±2.65 at final follow-up ( t=16.916, P<0.001) with significant difference. No patellar redislocation, skin necrosis, wound infection, or limited joint mobility occurred during follow-up. Conclusion:DDFO combined with knee extension device reconstruction is an effective and safe treatment for adolescent habitual patellar dislocation with severe torsional deformity, resulting in significant clinical and radiographic improvement with low complication rates.

Objective:To systematically evaluate qualitative research on weight regain experiences in post-bariatric surgery patients and provide insights for targeted weight management interventions.Methods:A comprehensive search was conducted in PubMed, Scopus, CINAHL, China National Knowledge Infrastructure, China Biology Medicine disc, and Wanfang data for qualitative studies on the experiences, perceptions, and feelings of post-bariatric surgery patients regarding weight regain. The search covered all available literature up to December 6, 2023. The 2016 Joanna Briggs Institute critical appraisal tool for qualitative research was used for quality assessment. Data were synthesized using the aggregative integration method.Results:A total of nine studies were included, yielding 17 core themes, which were categorized into five subcategories and further synthesized into two overarching themes: patients' awareness of weight management improved, but knowledge gaps, misconceptions, and inappropriate behaviors persisted; negative experiences were prevalent in the weight management process.Conclusions:The awareness of weight management in post-bariatric surgery patients needs to be strengthened. Healthcare professionals should identify high-risk individuals for weight regain, provide informational and social support, and help patients correct misconceptions and unhealthy behaviors to effectively prevent and manage weight regain.
