Childhood obesity is an escalating public health concern，with its prevalence rising year by year.This condition can lead to a series of metabolic disorders such as type 2 diabetes mellitus，hypertension，hyperlipidemia，and hyperuricemia.While various factors contribute to obesity，genetics plays a significant role，accounting for 40% to 70% of childhood obesity cases.Most of the identified loci harbor genes are involved in pathways affecting neuro-circuits that regulate appetite and satiety，insulin secretion and action，adipogenesis，and lipid metabolism.To date，using genome-wide association studies，over 1 100 obesity susceptibility loci have been identified，with notable examples being leptin，leptin receptor，and melanocortin-4 receptor gene.In this review，the correlation between genetic factors and childhood obesity and the possible mechanisms are elaborated to provide potential directions for its clinical management.

Objective:To compare the clinical features and prognosis between newly diagnosed diffuse large B-cell lymphoma(DLBCL)patients with and without hemophagocytic syndrome(HPS).Methods:The clinical data of 45 DLBCL patients in Gansu Provincial Hospital from January 2012 to December 2021 were retrospectively analyzed.The patients were divided into HPS group(15 cases)and non-HPS group(30 cases).The clinical features and prognosis of the two groups were compared,and survival analysis was performed using Kaplan-Meier method.Results:Patients with HSP were mostly characterized by fever,cytopenia and splenomegaly.The levels of ferritin and soluble CD25 increased in all patients.The level of fibrinogen decreased in 66.67％patients,while triglyceride increased in 53.33％patients,and bone marrow hemophagocytosis occurred in 80.00％patients.Compared with non-HSP group,the proportions of patients with advanced stage(Ann Arbor stage Ⅲ/Ⅳ)and lactate dehydrogenase(LDH)≥ 240 U/L were higher in HSP group(both P＜0.05).The median survival time of HSP group was 8.0 months,which was significantly shorter than 45.5 months of non-HSP group(P＜0.001).Conclusion:The DLBCL patients with HPS have later Ann Arbor stage,higher LDH and shorter overall survival time compared with patients without HPS.

Objective:To investigate the clinical characteristics and prognosis of primary bone marrow lymphoma.Methods:The clinical data of 6 patients with primary bone marrow lymphoma admitted to Gansu Provincial People's Hospital from February 2011 to March 2023 were collected,and their clinical characteristics and prognosis were retrospectively analyzed and summarized.Results:The median age of 6 patients was 61(52-74)years old.There were 2 males and 4 females.All patients had fever and abnormal blood routine examination.Physical examination and imaging examination showed no lymphadenopathy,no extranodal lesions in lung,gastrointestinal,liver and spleen,skin,etc.After strict exclusion of systemic lymphoma involvement in the bone marrow,the diagnosis was confirmed by bone marrow examination,5 cases were primary myeloid diffuse large B-cell lymphoma and 1 case was primary myeloid peripheral T-cell lymphoma(NOS).1 case abandoned treatment,5 cases received CHOP-like or combined R regimen,including 1 case of autologous stem cell transplantation.4 cases died and 2 case survived.The median OS was 5.5(1-36)months.Conclusion:The prognosis of primary marrow lymphoma is poor,and bone marrow-related examination is an important means of diagnosis.Diffuse large B-cell lymphoma is the most common histomorphologic and immune subtype,and autologous hematopoietic stem cell transplantation may improve the prognosis.

High-risk human papillomavirus (HPV)-related cancers consist of cervical cancer, anal cancer, penile cancer, vulvar cancer, vaginal cancer, and head and neck cancer (HNC). Of these, the disease burden of HNC is second only to cervical cancer. HNC mostly originates from malignant lesions of squamous epithelial cells and mainly includes oral cavity cancer, pharyngeal cancer (including nasopharyngeal cancer, oropharyngeal cancer, and hypopharyngeal cancer), and laryngeal cancer. Tobacco use, alcohol abuse, and HPV infection are three primary risk factors. Recently, there is an upward trend of HNC incidence globally, especially in high-income countries. In China, the disease burden and trends of HPV-related HNC are still not clear. A few small sample size and single-center studies suggest a high HPV prevalence and increasing trend in HNC. Methodological differences in HPV testing and regional variabilities still exist among these studies. Among the anatomic sites, oropharyngeal cancer has been shown to be caused by HPV infection, but the association of HPV with other sites is still under debate. In addition, there is a paucity of relevant studies. Here, this review narrates the association between HPV infection and HNC, compares the differences between global and Chinese studies, and then explores the importance of HPV infection in various anatomical sites. The main objective is to highlight the research on HPV-related HNC and promote relevant prevention and treatment programs.

The present study observed the regulatory effect of total flavonoids of Ziziphora clinopodioides on autophagy and the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt)/mammalian target of rapamycin(mTOR) signaling pathways in ApoE~(-/-) mice and explored the mechanism of total flavonoids of Z. clinopodioides against atherosclerosis(AS). ApoE~(-/-) mice were fed on a high-fat diet for eight weeks to induce an AS model. The model mice were randomly divided into a model group, a positive control group, and low-, medium-and high-dose groups of total flavonoids of Z. clinopodioides, while C57BL/6J mice fed on a common diet were assigned to the blank group. The serum and aorta samples were collected after intragastric administration for 12 weeks, and the serum levels of total cholesterol(TC), triglyceride(TG), low density lipoprotein-cholesterol(LDL-C), and high density lipoprotein-cholesterol(HDL-C) were detected by an automatic biochemical analyzer. The serum expression levels of intercellular adhesion molecule-1(ICAM-1), vascular cell adhesion molecule-1(VCAM-1), matrix metalloproteinase-2(MMP-2), and matrix metalloprotei-nase-9(MMP-9) were detected by enzyme-linked immunosorbent assay(ELISA). Oil red O staining was used to observe the aortic plaque area in mice. Hematoxylin-eosin(HE) staining was used to observe the aortic plaque and pathological changes in mice. The expression of P62 and LC3 in the aorta was detected by the immunofluorescence method. The protein expression of LC3Ⅱ/Ⅰ, Beclin-1, P62, p-PI3K, p-Akt, and p-mTOR in the aorta of mice was detected by Western blot. The results showed that compared with the blank group, the serum levels of TC, TG, LDL-C, ICAM-1, VCAM-1, MMP-2 and MMP-9 in the model group were significantly increased(P<0.01 or P<0.05), the content of HDL-C was decreased(P<0.05), intra-aortic plaque area was enlarged(P<0.01), the expression of LC3 in the aorta was significantly down-regulated, P62 expression was up-regulated(P<0.01 or P<0.05), the expressions of LC3Ⅱ/Ⅰ and Beclin-1 in the aortic lysate were significantly down-regulated, and the expressions of p-PI3K, p-Akt, p-mTOR and P62 were significantly increased(P<0.01). The medium-and high-dose groups of total flavonoids of Z. clinopodioides could reduce the serum levels of TC, TG, LDL-C, ICAM-1, VCAM-1, MMP-2, and MMP-9 in AS model mice(P<0.01 or P<0.05), and increase the content of HDL-C(P<0.01 or P<0.05). The aortic plaque area of mice after middle and high doses of total flavonoids of Z. clinopodioides was significantly reduced(P<0.01), the content of foam cells decrease, and the narrowing of the lumen decreased. The total flavonoids of Z. clinopodioides significantly increased the expression of LC3 in the aorta and the expression of LC3Ⅱ/Ⅰ and Beclin-1 in the lysate, and decreased the expression of P62 in the aorta and the expression of p-PI3K, p-Akt, p-mTOR and P62 in the lysate(P<0.01 or P<0.05). The results showed that the total flavonoids of Z. clinopodioides could improve the content of blood lipids and inflammatory factors, and reduce the generation of foam cells and plaques in aortic tissue, and the mechanism may be related to the regulation of PI3K/Akt/mTOR signaling pathway.

The pandemic of COVID-19 threatens the health and safety of the people all over the world. COVID-19 vaccine is the key public product to establish population immune barrier and achieve the global contain of the pandemic. The World Health Organization, the Global Alliance for Vaccines and Immunization and the Coalition for Epidemic Preparedness Innovations established COVID-19 Vaccines Global Access Facility (COVAX) in 2020, aiming to enable the fair access to COVID-19 vaccine by all countries in the world, especially the low- and middle-income countries. Although COVAX has facilitated the production and research of COVID-19 vaccine by coordinating the global supply chain, the implementation of COVAX is still facing many difficulties in financing, implementation and the awareness of public, revealing the problems of global health governance. Taking COVAX as an example, this paper analyzes the difficulties faced by global health governance and explore the underlying causes, so as to suggest feasible short and long-term paths for China's participation in global governance.

Objective: We aim to evaluate the morbidity and mortality of cancer attributable to human papillomavirus (HPV) infection in China in 2016. Methods: Based on the cancer incidence and mortality rates, national population data, and population attributable fraction (PAF) in China, we calculated the number of incidence and death cases attributed to HPV infection in different areas, age groups, and gender in China in 2016. The standardized incidence and mortality rates for cancer attributed to HPV infection were calculated by using Segi's population. Results: In 2016, a total of 124 772 new cancer cases (6.32 per 100 000) were attributed to HPV infection in China, including 117 118 cases in women and 7 654 cases in men. Of these cancers, cervical cancer was the most common one, followed by anal cancer, oropharyngeal cancer, penile cancer, vaginal cancer, laryngeal cancer, oral cancer, and vulvar cancer. A total of 41 282 (2.03 per 100 000) deaths were attributed to HPV infection, of which 37 417 occurred in women and 3 865 in men. Most deaths were caused by cervical cancer, followed by anal cancer, oropharyngeal cancer, penile cancer, laryngeal cancer, vaginal cancer, oral cancer, and vulvar cancer. The incidence and mortality rates of cervical cancer increased rapidly with age, peaked in age group 50-54 years, then decreased obviously. The morbidity and mortality rates of non-cervical cancer increased with age. The cancer case and death numbers in rural areas (57 089 cases and 19 485 deaths) were lower than those in urban areas (67 683 cases and 21 797 deaths). However, the age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) of cervical cancer were higher in rural areas than in urban areas. There were no significant differences in ASIR and ASMR of non-cervical cancers between urban areas and rural areas. Conclusions: The incidence of cancers attributed to HPV infection in China was lower than the global average, but the number of incidences accounted largely, furthermore there is an increasing trend of morbidity and mortality. The preventions and controls of cervical cancer and male anal cancer are essential to contain the increases in cancer cases and deaths attributed to HPV infection.
