Objective:To investigate the multimorbidity of myopia and obesity, as well as myopia and malnutrition, among children and adolescents aged 7-18 in Guangdong Province and analyze their epidemiological characteristics and related factors.Methods:A stratified random cluster sampling method was used to select 274 939 children and adolescents aged 7-18 from 21 cities in Guangdong Province in 2023. Physical examination information such as height, weight, distance vision, and diopter, as well as questionnaire survey information on dietary behavior, physical activity, screen behavior, sleep time, etc., were collected to analyze the current status and trends of multimorbidity between myopia and obesity, myopia and malnutrition. The multivariate logistic regression model was used to analyze the related factors of multimorbidity.Results:The multimorbidity rates of myopia and obesity, myopia and malnutrition in children and adolescents aged 7-18 in Guangdong Province in 2023 were 4.43% and 6.40%, respectively. The multimorbidity rates for males were 5.44% and 6.88%, respectively, which were higher than those for females, about 3.31% and 5.88% (both P<0.001). The multimorbidity rates of urban students were 5.03% and 6.73%, respectively, which were higher than those of county students at 4.03% and 6.18% (both P<0.001). The multimorbidity rates of myopia and obesity, myopia and malnutrition increased with the increase of academic stage (all P<0.001). The multimorbidity rates of myopia and obesity, as well as myopia and malnutrition, fluctuated with age, with the first decrease occurring at the age of 12. The multivariate logistic regression analysis showed that compared to children and adolescents aged 7-18 who had daily after-school tutoring <2 hours, daily screen time <2 hours, did not consume sugary drinks every day, sleep time that could meet health requirements daily, and exercised≥60 minutes of moderate-to vigorous-physical activity ≥60 minutes for at least 3 days per week, those who had daily after-school tutoring ≥2 hours ( OR=1.18, 95% CI: 1.11-1.26), daily screen time ≥2 hours ( OR=1.09, 95% CI: 1.02-1.16), consumed sugary drinks every day ( OR=1.20, 95% CI: 1.11-1.30), daily sleep time that could not meet the health requirements ( OR=1.16, 95% CI: 1.09-1.23), and no exercise per week ( OR=1.09, 95% CI: 1.01-1.18) had a higher risk of multimorbidity of myopia and obesity. Compared to children and adolescents who exercised≥60 minutes of moderate-to vigorous-physical activity ≥60 minutes for at least 3 days per week, those who exercised <3 days per week ( OR=1.20, 95% CI: 1.17-1.34) had a higher risk of multimorbidity of myopia and malnutrition. Conclusion:The multimorbidity rates of myopia and obesity, as well as myopia and malnutrition, in children and adolescents aged 7-18 in Guangdong Province are relatively low and fluctuate with age. Physical activity, screen time, consumption of sugary drinks, and sleep time may be associated with these multimorbidities.

Objective To confirm the clinical effectiveness of Duntu Lishui stage acupuncture on polycystic ovary syndrome insulin resistance(PCOS-IR),and to examine the relationship between changes in inflammatory factor levels and improvements in PCOS-IR clinical indicators.Methods 70 individuals with PCOS-IR were randomly assigned to one of two groups:metformin(control)or Duntu Lishui stage acupuncture(Guan Yuan,Zhong Ji,San Yinjiao,Zu Sanli,Feng Long were selected every other day)combined with metformin(acupuncture).35 individuals for each group.TCM symptom scores and sign scores(hirsutism)were collected before and after therapy for a period of three months.Sex hormones,blood lipids,fasting blood glucose,fasting insulin,and serum levels of inflammatory factors IL1β and IL18 were all measured.Results The effective rate of the control group was 48.57%,and the effective rate of the acupuncture group was 94.29%,with a statistically significant difference(P<0.01).Compared within the group before and after treatment,the scores of TCM symptoms,signs,FPG,FINS,and HOMA-IR,TG,LDL-C,LH,LH/FSH,T,PRL,IL18 and IL1β all decreased,while the levels of E2 and P increased,with statistical difference(P<0.05);comparison between groups,acne score,Acanthus nigricans score,FINS,HOMA-IR,TG,LDL-C,LH,LH/FSH,T,IL18 and IL1β decreased,while HDL-C and FSH levels increased,with statistical difference(P<0.05).Pearson correlation analysis revealed that changes in IL1β and IL18 levels prior to and after therapy were significantly positively linked with changes in BMI,LH,T,FINS,HOMA-IR,and TG(R value>0.40,P<0.05).Conclusion Duntu Lishui acupuncture combined with metformin can considerably improve glucose and lipid metabolism,reduce insulin resistance,and control sex hormone levels in patients with PCOS-IR,and the therapeutic impact is superior to that of Western treatment alone.According to Pearson correlation research,inflammatory variables may be a significant target for the therapeutic effects of acupuncture and moxibustion.

Dental implantology has developed rapidly for over half a century,since pure titanium(99.7％)dental cylindrical threaded implants were exploited and osseointegration was introduced in 1960s by Prof.Br?nemark.The long term retention rates of 10 years or more are over 95％.However,the biological complications jeopardize the long term effects of dental implant treatment seriously.The prevalence of dental implant biological complications varies greatly among different reports resulting from the disparities on the defini-tions of dental implant biological complications.After analyzing and summarizing the major opinions proposed internationally in recent years,the consensus for the definition of dental implant biological complications has been reached.Generally the dental implant biologi-cal implications can be classified into early stage(before restoration)biological complications and late stage(after restoration)biological complications.The early stage biological complications include acute and chronic infections,pain,soft tissue deficiency,and osseointegration failure,etc.The late stage complications include peri-implant diseases(peri-implant mucositis and peri-implantitis),soft tissue deficiency around implant,implant loosening and dropping off,etc.The various risk factors related to different dental implant biological complications,the strategies of the prevention and treatment for the dental implant biological complications have been discussed comprehensively,and the consensus has been reached.It is aimed to advocate the dentist to pay more attention to the early prevention of the biological implant complications,to promote more researches on the implant biological complications,and to help elevate the level of dental implantology in our country.

In China, the number of chronic pain patients has exceeded 300 million, making chronic pain the third major health problem after tumors and cardiovascular diseases. Particularly concerning is the gradual emergence of hypertension and chronic low back pain as public health problems that threaten public health and increase the global economic burden. Modern research shows that the incidence of coexisting hypertension is higher among patients with chronic low back pain. Additionally, evidence indicates that the use of NSAIDs for pain relief can have adverse effects on blood pressure, and some antihypertensive medications may trigger symptoms of low back pain. Thus, addressing chronic pain in hypertensive patients while stabilizing blood pressure is one of the important research questions in the modern treatment of hypertension among middle-aged and elderly individuals. From ancient to modern traditional Chinese medicine(TCM) theory, kidney deficiency has been regarded as the core pathogenesis of low back pain. Recent clinical practices and literature indicate that kidney deficiency plays a crucial role in the modern pathogenesis of hypertension. Both hypertension and chronic low back pain are closely associated with kidney deficiency in TCM theory, revealing a potential mechanism linking the two conditions. Combining the theories of " kidney-essence-marrow" and " nourishing water to moisten wood", a therapeutic strategy centered on tobifying kidney was proposed, including selecting single drugs with kidney-tonifying effects as well as compound formulations and elaborating modern research evidence. The aim is to achieve stable blood pressure control in hypertension patients with chronic low back pain while providing a new treatment perspective for chronic low back pain. This article systematically elaborates on the understanding of hypertension combined with chronic low back pain from both TCM and modern medicine, as well as the therapeutic strategy involving kidney-tonifying drugs, to offer useful references for clinical practice.

This study aims to explore the mechanism of lung and gut protection by Tanreqing Capsules on the mice infected with influenza virus based on "the lung-gut axis". A total of 110 C57BL/6J mice were randomized into control group, model group, oseltamivir group, and low-and high-dose Tanreqing Capsules groups. Ten mice in each group underwent body weight protection experiments, and the remaining 12 mice underwent experiments for mechanism exploration. Mice were infected with influenza virus A/Puerto Rico/08/1934(PR8) via nasal inhalation for the modeling. The lung tissue was collected on day 3 after gavage, and the lung tissue, colon tissue, and feces were collected on day 7 after gavage for subsequent testing. The results showed that Tanreqing Capsules alleviated the body weight reduction and increased the survival rate caused by PR8 infection. Compared with model group, Tanreqing Capsules can alleviate the lung injury by reducing the lung index, alleviating inflammation and edema in the lung tissue, down-regulating viral gene expression at the late stage of infection, reducing the percentage of neutrophils, and increasing the percentage of T cells. Tanreqing Capsules relieved the gut injury by restoring the colon length, increasing intestinal lumen mucin secretion, alleviating intestinal inflammation, and reducing goblet cell destruction. The gut microbiota analysis showed that Tanreqing Capsules increased species diversity compared with model group. At the phylum level, Tanreqing Capsules significantly increased the abundance of Firmicutes and Actinobacteria, while reducing the abundance of Bacteroidota and Proteobacteria to maintain gut microbiota balance. At the genus level, Tanreqing Capsules significantly increased the abundance of unclassified＿f＿Lachnospiraceae while reducing the abundance of Bacteroides, Eubacterium, and Phocaeicola to maintain gut microbiota balance. In conclusion, Tanreqing Capsules can alleviate mouse lung and gut injury caused by influenza virus infection and restore the balance of gut microbiota. Treating influenza from the lung and gut can provide new ideas for clinical practice.

This study investigated the therapeutic effects and mechanisms of Modified Yiyi Fuzi Baijiang Powder on ulcerative colitis(UC) in rats from the perspective of dampness. SD rats were randomly allocated into six groups(n=10): control, model, mesalazine, and Modified Yiyi Fuzi Baijiang Powder at low(3.96 g·kg~(-1)·d~(-1)), medium(7.92 g·kg~(-1)·d~(-1)), and high(15.84 g·kg~(-1)·d~(-1)) doses. UC was induced in all groups except the control by administration with 3% dextran sulfate sodium(DSS) solution for 7 days. The disease activity index(DAI) was recorded, and the colon tissue was collected for analysis. Histopathological changes were assessed by hematoxylin-eosin staining. Serum levels of D-lactic acid(D-LA) and diamine oxidase(DAO) were measured by ELISA. Immunohistochemistry and PCR were employed to evaluate the expression of aquaporins(AQP3, AQP4) and tight junction proteins [zonula occludens-1(ZO-1) and occludin] at both protein and mRNA levels. Compared with the control group, the model group showed an increased DAI scores(P<0.05), intestinal mucosal damage, elevated serum levels of DAO and D-LA(P<0.05), and decreased expression of AQP3, AQP4, ZO-1, and occludin(P<0.05). Treatment with Modified Yiyi Fuzi Baijiang Powder reduced the DAI scores(P<0.05), lowered the serum levels of D-LA and DAO(P<0.05), and upregulated the expression of AQP3, AQP4, ZO-1, and occludin at both protein and mRNA levels compared with the model group. These findings suggest that Modified Yiyi Fuzi Baijiang Powder exerts therapeutic effects on UC by reducing the intestinal mucosal permeability, promoting colonic mucosal repair, and regulating abnormal intestinal water metabolism, which may involve the upregulation of AQP3 and AQP4 expression.

OBJECTIVES: To study the clinical characteristics of pediatric Behçet syndrome (BS). METHODS: A retrospective review was conducted on the medical records of children hospitalized in the Department of Pediatrics at the Second Hospital of Hebei Medical University between December 2014 and December 2024 who met diagnostic criteria for BS. RESULTS: Among 45 children with BS, 26 (58%) were male. Oral aphthous ulcers were the most common manifestation (43/45, 96%), followed by genital ulcers (23/45, 51%) and gastrointestinal involvement (18/45, 40%). Genital ulcers were more frequent in girls, whereas ocular involvement was more common in boys (P<0.05). The pathergy test was positive in 10 (22%), and HLA-B51 was positive in 13 (29%). Fecal calprotectin (FC) was elevated in 16 (36%); gastrointestinal involvement was more frequent in children with elevated FC than in those with normal FC (P<0.05). According to the respective criteria, 17 (38%) patients met the International Study Group criteria (1990), 33 (73%) met the International Criteria for Behçet Disease (2014), and 13 (29%) met the Pediatric Behçet Disease criteria (2015). CONCLUSIONS Pediatric BS shows marked clinical heterogeneity. HLA-B51 is associated with disease susceptibility.
