AIM:To observe the effect of acupuncture on adenosine A1 receptor(A1R)in the caudate puta-men(CPu)of complete Freund's adjuvant(CFA)rats,and to explore the potential mechanism of acupuncture in treat-ment of inflammatory pain.METHODS:Sixty-four 6～8-week-old male Wistar rats were randomly divided into saline group,model group(CFA group),CFA+manual acupuncture(MA)group,CFA+solvent dimethyl sulfoxide(DMSO)group,CFA+A1R agonist 2-chloro-N6-cyclopentyladenosine(CCPA)group,CFA+A1R antagonist 8-cyclopentyl-1,3-di-propylxanthine(DPCPX)group,CFA+MA+DMSO group and CFA+MA+DPCPX group.In MA groups,on the 2nd day af-ter modeling,the rats were needled at Zusanli points on both sides,30 min at a time,once per day,for 7 d.Pain threshold of plantar thermal radiation was used to observe the pain response of the rats.The content of cyclic adenosine monophos-phate(cAMP)in the CPu was detected by ELISA.The protein expression and phosphorylation levels of protein kinase A(PKA)and cAMP response element-binding protein(CREB)were detected by Western blot.The expression of A1R in the CPu was detected by immunofluorescence staining.RESULTS:Compared with saline group,CFA modeling signifi-cantly lowered the thermal pain threshold of the rats(P<0.01).Compared with CFA group,the thermal pain threshold of the rats in CFA+MA group and CFA+CCPA group was significantly increased(P<0.05 or P<0.01).Compared with CFA+ MA+DMSO group,the thermal pain threshold of the rats in CFA+MA+DPCPX group was decreased(P<0.05).Compared with CFA group,A1R protein relative expression level and positive cells in the CPu of the rats in CFA+MA group were in-creased(P<0.05 or P<0.01).Compared with saline group,cAMP content and p-CREB protein level in the CPu of the rats in CFA+MA group were decreased(P<0.05).Compared with CFA+DMSO group,cAMP content and p-CREB pro-tein level in CFA+MA+DMSO and CFA+CCPA groups were significantly decreased(P<0.01).Compared with CFA+MA+ DMSO group,the levels of cAMP,p-PKA and p-CREB in CFA+MA+DPCPX group were significantly increased(P<0.05 or P<0.01).CONCLUSION:Acupuncture on bilateral Zusanli can relieve inflammatory pain in CFA rats,and its mech-anism may be related to A1R/cAMP/p-CREB signaling pathway.

Objectives:To examine the proportion and trends of cervical adenocarcinoma in cervical cancer (ICC), mainly including cervical adenocarcinoma (CADC) and squamous cervical cancer (SCC) in China, and to analyze the distribution of human papilloma virus (HPV) in CADC and SCC.Methods:Published studies reporting HPVs distribution in various histological types or relative proportions of CADC in ICC in China were identified manually and searched systematically in Medline, Embase, Cochrane Library databases, CNKI and Wanfang since the databases were established until October 2022. Meta-analysis was performed using Stata 16.0 software. And we applied the random-effects models to estimate the combined effect values due to the high heterogeneity.Results:Twenty-three studies were eligible. The relative prevalence of CADC was 9.0% (95% CI, 7.7%－10.3%). According to the diagnosis time of ICC, the patients were divided into three time periods, which is 1979-2005, 2006-2011, 2012-2022 respectively. The prevalence of CADC by time was: 6.0% in 1979-2005, 8.1% in 2006-2011, and 9.5% in 2012-2022, respectively, with no statistically significant trend in proportions over time (χ 2=5.03, P=0.081). Meanwhile, the percentage of CADC also varies by regions, and the highest percentage of CADC was found in the eastern region (11.2%), followed by the western region (7.3%) and the central region (5.9%). The total prevalence of HPV infection in CADC was 72.3%, which was lower than 92.0% in SCC, and the difference was statistically significant (χ 2=300.89, P＜0.01). To be specific, the top three HPV types prevalent in CADC were HPV18 (45.0%), HPV16 (22.0%), and HPV52 (7.3%), and those prevalent in the SCC were HPV16 (64.2%), HPV52 (5.6%), HPV18 (5.4%). The results of the Egger's test, and Begg's test showed that there was no publication bias in this study and sensitivity analysis showed that the results of this study were fairly stable. Conclusions:The proportion of CADC in China has increased in a limited way in the past decades, and there are regional differences in the proportion of CADC. The predominant type is HPV18 in CADC and HPV16 in SCC. To eliminate the limitations of the secondary literature, a multicenter study with consistent diagnostic levels and identical HPV genotyping tests is still needed in the future to better characterize the relative proportion of cervical adenocarcinoma and the trend of HPV changes, which will provide a basis for the improvement of HPV vaccine and screening policies.

Objective To investigate the cognition of colorectal cancer-related knowledge and influencing factors of patients with middle- and advanced-stage colorectal cancer in ethnic minority areas of Inner Mongolia. Methods According to the national population and the prevalence of colorectal cancer, 277 patients with colorectal cancer were selected by stratified and random sampling in Inner Mongolia. The patients were surveyed in Baotou, Chifeng, Bayannaoer, and other hospitals. The questionnaire included patients' basic information, cognition of colorectal cancer risk factors and screening knowledge, screening information, etc. Results Before suffering from the disease, the patients' knowledge of colorectal cancer (risk factors, early screening knowledge, treatment methods) was low. About 54.9% of patients were unaware of high risk factors for colorectal cancer, 75.8% of patients did not understand the knowledge of early screening of colorectal cancer, and 37.5% of patients did not underst and the treatment of colorectal cancer. The main influencing factors of colorectal cancer cognition were education level and occupation. Patients who work in institutions and enterprises and with higher education level had better cognition. Conclusion Patients with middle- and advanced-stage colorectal cancer in Inner Mongolia have poor knowledge and awareness of risk factors and screening of colorectal cancer before diagnosis. Education level and occupation are factors influencing colorectal cancer cognition, therefore, people with low knowledge rate of colorectal cancer and low education level as well as unemployed laid-off people should be given priority intervention.

MSM are a high-risk population for HPV infection and related diseases. MSM can be effectively protected by quadrivalent and nine-valent HPV vaccines. This paper outlines the significance of providing HPV vaccination to MSM, summarizes the basis of HPV vaccination in MSM, and puts forward the following recommendations. First, China should expedite the development and approval of the HPV vaccine for male use. Second, HIV-positive MSM should vaccinate against HPV as soon as possible. Third, prioritize HPV vaccination for MSM individuals aged 26 or less. Fourth, for MSM aged over 26, catch-up vaccination or opportunistic vaccination should be provided when HPV vaccine resources are sufficient. Implementing this vaccination strategy can provide protection for the MSM and control the spread of sexually transmitted diseases.

Human papillomavirus (HPV) is the most common sexually transmitted virus, of which high-risk HPV mainly infects mucosal epithelial cells causing malignant transformation of the cells. HPV infection could ultimately develop to malignant tumors including cervical, head and neck, anal, penile, vulvar, and vaginal cancers. The burden of cervical cancer is highest among these cancers and high-risk HPV persistent infection is considered an etiologic factor in its development. Therefore, it is crucial to identify early infected cases and determine HPV infection status by HPV testing. HPV testing can also be used for prophylactic HPV vaccine efficacy assessment, triage of women with cytological abnormalities, prediction of post-treatment efficacy and identification of HPV-attributable malignant lesions. There is the scarcity of studies elucidating the existing HPV detection methodologies. Through providing a comprehensive landscape of the currently available HPV detection methodologies, including their principles, applications, and clinical use, the ultimate objective is to provide information for the clinical practice of HPV detection, so as to reduce the incidence and mortality rates of HPV-associated diseases.

Esophageal cancer (EC) is one of the most fatal cancers worldwide. According to GLOBOCAN 2020, it was estimated that there were 600, 000 new EC cases and 540 000 EC deaths, while nearly half of all newly diagnosed cases of EC and associated deaths worldwide occurred in China. The annual incidence and mortality of EC have been reduced in the last 20 years in China. However, the early symptoms and signs of EC are not easily distinguished and the disease tends to be within the middle and late stage of pathogenesis when identified, leading to its low 5-year survival rate. Therefore, it could help effectively reduce the burden of EC by clarifying its etiology and risk factors, as well as taking preventive and early diagnosis measures. This article reviews the epidemiology, etiology, screening and early diagnosis of EC in China, to provide systematic references for EC prevention and control.

Objective To understand and evaluate the knowledge, attitude and practice of female human papillomavirus and HPV vaccine in Chinese mainland. Methods We searched the relevant studies about the knowledge, attitude and behavior factors of HPV infection and HPV vaccine published in PubMed, MEDLINE, CNKI and Wanfang databases about Chinese mainland women from January 1, 1995 to January 31, 2021.Two researchers independently screened the literatures, extracted data and the literatures with quality score≥5 points.Chi square test was used to evaluate its heterogeneity.Begg' s test was used to evaluate publication bias. Results A total of 33 literatures were included, with a total number of 46013 people.The results showed that the total awareness rate of HPV in the population was 65.9%, the lowest rates were 16.0%, 41.2% and 14.4% in Northeast, rural areas and middle school students, respectively; while the highest rates of HPV were 77.4%, 56.3% and 71.0% in Central China, cities and towns and college students, respectively.The main source of HPV knowledge was the network/WeChat official account number (38.9%), and the lowest was family/friend (4.5%).The population's awareness rate of HPV vaccine related knowledge was 41.4%, the highest rates were 51.8% and 69.7% in East China and medical staff, respectively, while the lowest were 23.6% and 12.7% in Southwest and middle school students. Conclusion In order to achieve the total elimination of cervical cancer in China by 2030 as soon as possible, people should strengthen their awareness of HPV and HPV vaccine related knowledge.
