Objective To explore the effectiveness of the cumulative sum (CUSUM) and the exponentially weighted moving average (EWMA) for early warning of influenza epidemic using two datasets of reported influenza cases and influenza-like illness (ILI) cases. Methods Using the reported cases of influenza and ILI in Daxing District, Beijing, from week 23 of 2018 to week 22 of 2024 as data sets, the CUSUM and EWMA models were established, respectively. The positive rate of influenza etiology was used as the ^“gold standard^”, and the Youden index was used as the evaluation index to compare the early warning effect of the two models under different data sets and different parameters. Results In CUSUM, the optimal Youden indices of the reported influenza cases set and the ILI cases set were 0.751 and 0.635, respectively. In EWMA, the optimal Youden indices of the reported influenza cases set and the ILI cases set were 0.544 and 0.464, respectively. The optimal EWMA and CUSUM models could both issue early warning signals in advance of the ^“gold standard^”. Conclusion In the influenza epidemic early warning in Daxing District, Beijing, the CUSUM model established with the reported cases of influenza can achieve good early warning effects, but the model parameters need to be dynamically adjusted according to the local epidemic characteristics.

Objective: To investigate the status and associated factors of sports supplement usage among grade 9 students, so as to provide a scientific basis for targeted supervision and health education regarding sports supplement usage among junior high school students. Methods: From June to September 2025, a stratified cluster random sampling method was used to select 2 261 grade 9 students from 10 provinces (autonomous regions, municipalities) in China. A questionnaire survey was conducted on their sports supplement usage and related factors. The Chi square test was used to compare the usage rates of sports supplements among different groups of students, and binary Logistic regression analysis was employed to investigate the related factors of sports supplement usage among grade 9 students. Results: Totally 59.7% of the grade 9 students used sports supplements. The usage rate (62.5%) was higher among boys than girls (56.3%), higher among students from rural areas and towns/counties (66.5%, 66.2%) than those from urban districts (52.9%), higher among boarding students (65.2%) than non resident students (54.3%), higher among students whose parents occupations were businessmen and workers (fathers: 65.0%, 63.7%; mothers: 63.6%, 61.1%) than those whose parents were farmers and civil servants (fathers: 57.5%, 54.1%; mothers: 58.8%, 55.7%), higher among students with a monthly family income of 5 000- 10 000 yuan (66.3%) than those in other income groups, and higher among students in the high score zone for the entrance physical examination to senior high school (67.7%) than those in the medium and low score zones ( 56.3% , 56.5%) ( χ 2=8.99, 42.21, 27.98, 20.55, 8.20, 22.74, 24.70, respectively, all P <0.05). Binary Logistic regression analysis showed that boys ( OR =1.26), those from rural areas ( OR =1.59), boarding students ( OR =1.36), those with a monthly family income of 5 000- 10 000 yuan ( OR =1.41), and those in the high score zone for entrance physical examination to senior high school ( OR =1.34) were more likely to use sports supplements during the entrance physical examination to senior high school; the probability of sports supplement usage was lower among students whose fathers were civil servants ( OR =0.74) (all P <0.05). Conclusions The usage of sports supplements is relatively common among grade 9 students. Intervention measures should be targeted at specific populations to reduce the risk of misuse.

This article systematically reviews and examines the historical evolution of Bambusae Succus as a medicinal material， covering aspects such as nomenclature， origin， geographical distribution， harvesting and processing methods， quality assessment， therapeutic effects and indications， by consulting ancient herbal texts， medical compendia， and modern literature. The aim is to provide a reference for the development and utilization of famous classical formulas containing this herb. Research indicated that Bambusae Succus was first documented in the Shennong Bencaojing during the Han dynasty， with Zhuli being the standard name used throughout history， alongside aliases like Zhuzhi， Zhuyou and Huoquan. Historically， the primary source of Bambusae Succus has been Phyllostachys nigra var. henonis（Danzhu）， although other species such as Pleioblastus amarus and Bambusa emeiensis have also been used medicinally. Ancient records predominantly noted its origin in Yizhou（present-day Chengdu and surrounding areas in Sichuan） and the Wuling region（between present-day Hunan， Guangdong， Guangxi and Jiangxi provinces）， while contemporary sources are mainly from regions south of the Yangtze River and southwestern China. Traditionally， Bambusae Succus was harvested from bamboo that had grown for exactly one year， today， it can be collected year-round without strict age requirements. Ancient preparation methods included direct fire roasting or dry distillation， whereas modern industrial production employs dry distillation， reflux extraction， and percolation. In terms of quality evaluation， ancient texts considered a sweet taste to be superior， while today， clarity and transparency are prioritized. Historically， Bambusae Succus was characterized as sweet and cold nature， targeting the lung and stomach meridians， with uses evolving from clearing heat and resolving phlegm to nourishing Yin， moistening dryness， and relaxing tendons and unblocking meridians. Modern descriptions classify it as sweet， bitter， and cold in nature， affecting the heart， liver， and lung meridians， with functions including clearing heat， resolving phlegm， and facilitating orifices. It is indicated for conditions such as stroke with phlegm confusion， lung heat with phlegm congestion， convulsions， epilepsy， excessive phlegm in febrile diseases， high fever with thirst， irritability during pregnancy， and tetanus， with more clearly defined applications. Based on the results of the research， it is recommended that when developing and utilizing famous classical formulas containing Bambusae Succus， the one-year-old Phyllostachys nigra var. Henonis， which has been highly praised throughout history， should be selected as the source material. Industrial production should adopt the dry distillation method. Furthermore， in-depth research should be conducted on the modern technological characterization of the traditional quality control indicator of sweet taste， and reasonable modern quality control standards should be established.

Complex tumors of the maxillofacial region are difficult and risky to operate due to the complex anatomical structure and the proximity of multiple important neurovascular vessels,which is a great challenge for surgeons.Traditional single-mode imaging often requires physicians to synthesize different image features for analysis,and this kind of detached diagnosis brings great inconvenience to clinical practice.In recent years,with the increasing application of digital technology in the treatment of maxillofacial tumors,it is pos-sible to display the tumor site,invasion range and its relationship with neurovascularity in a more three-dimensional and intuitive way,which greatly reduces the risk of surgery.In this paper,we focus on the clinical application of multimodal medical image fusion technol-ogy in complex maxillofacial tumors and its joint application with digital surgical technologies such as rapid prototyping technology,mixed reality technology,surgical navigation,surgical robotics,artificial intelligence,etc.,to give an overview and outlook.

Oocyte maturation disorders and fertilization failures are caused by a variety of factors, including complex factors such as chromosomal abnormalities and poor oocyte quality. With the widespread use of high-throughput sequencing technology, more and more genetic mutations have been found to be associated with oocyte maturation and fertilization process in infertile patients. This paper summarizes and discusses 11 key genes ( TRIP13, TBPL2, LHX8, PATL2, TUBB8, CDC20, WEE2, ZP, ASTL, JUNO and CD9) related to oocyte maturation and fertilization-related disorders in females, providing a basis for research on the prevention of diseases associated with oocyte maturation blockage and fertilization failure and the development of targeted therapies.

Inflammatory lung diseases are cur-rently a major challenge threatening human health and life.Imbalanced inflammation and excessive in-flammation can lead to tissue damage and trigger the occurrence and development of systemic dis-eases.Anti-inflammatory treatment is of vital im-portance for improving patient survival and quality of life.In recent years,significant progress has been made in the exploration and research of drug targeting strategies,effectively addressing issues such as slow onset,low bioavailability,and rapid in vivo clearance rates during drug delivery.Drug tar-geting can increase local drug concentrations,re-duce dosing frequency,and mitigate side effects.This review primarily elaborates on the classifica-tion and characteristics of inflammatory lung dis-eases.It comprehensively reviews targeted drug de-livery strategies for inflammatory lung diseases from three perspectives:local targeting,passive tar-geting,and active targeting.Furthermore,it dis-cusses the prospects and challenges of drug target-ed therapy for lung diseases,potentially providing new research and application ideas for the target-ed treatment of inflammatory lung diseases.

Objective:To compare the effects of various exercise intervention programs on executive function in children.Methods:Experimental studies on the impact of exercise intervention on children's executive function were searched from CNKI,Wanfang,Pubmed,Web of Science,Embase and Cochrane repositories until December 2022,and the quality of included literatures was assessed with Cochrane bias risk assessment tool.The inclusion and exclusion criteria were developed according to the PICOS principle,and standardized mean difference(SMD)was used as the effect indicator.Results:A total of 43 literatures(n=5 333)were included.The results of meta-analysis showed that the ball game with single exercise time≥51 min,twice a week,intervention cycle ≥ 17 weeks was the first choice for promoting children's inhibition control(SUCRA=86.8);the ball game with a single exercise time of 10-30 min,twice a week,intervention period of 5-8 weeks was the first choice for promoting children's work-ing memory(SUCRA=75.6).The ball game with a single exercise time of 31-50 minutes,twice a week,inter-vention period of 5-8 weeks was the first choice for promoting children's cognitive flexibility(SUCRA=89.4).Conclusion:Different exercise intervention programs have different effects on executive function in children.

Objective To analyze the epidemiological and clinical characteristics of scrub typhus in Liuyang People's Hospital Hunan Province for better diagnosis,treatment,prevention and control of scrub typhus.Methods A retrospective study was conducted on 159 confirmed cases of scrub typhus.The demographic data of patients,clinical manifestations of scrub typhus,laboratory tests,and chest CT findings,complications,treatment,and outcomes were analyzed.Results The 159 patients with scrub typhus included 142 males and 17 females.The average age of patients was(53.8±11.9)(18-82)years old.The peak incidence of scrub typhus was in the period from July to September(87.42％).The common clinical manifestations included fever(97.48％),headache(41.51％),and fatigue(23.90％).The most common signs were eschar(92.45％)on the lower limbs(25.16％),scrotum(15.72％),and buttocks(11.32％).Laboratory test results upon admission showed decreased platelet count(64.15％),elevated creatinine(38.36％),elevated AST(90.57％),ALT(80.50％),and LDH(90.57％).Pulmonary imaging study revealed pulmonary inflammation(22.64％),pleural effusion(13.21％),and pericardial effusion(6.29％).The common complications included liver impairment(69.81％)and decreased platelet count(50.94％),as well as other complications such as renal dysfunction,myocardial injury,sepsis,respiratory failure,and disseminated intravascular coagulation(DIC).Doxycycline-based therapies resulted in cure rate of 98.11％(156/159).Three patients died due to severe complications.Conclusions The peak incidence of scrub typhus was in the period from July to September in Hunan Province.Eschar is a key feature for clinical diagnosis.Scrub typhus can affect multiple organ systems,leading to various systemic complications.The cure rate is high with doxycycline treatment,but some patients may die from severe complications due to delayed medical treatment.
