OBJECTIVE: To explore the curative effect of pediatric chronic sinusitis and analyze its relative factors, so that the best treatment plan and operation time can be choose. METHOD: Two hundred and twenty cases of pediatric chronic sinusitis were divided into 4 groups: group A with only simple chronic sinusitis, group B accompanied adenoid hypertrophy. Among group B, group B1 with no nasal cavity structural abnormalities but group B2 on the contrary. Group C accompanied only nasal cavity structural abnormalities. According to the documents, all patients were administered with standard and systematical three-stage treatment. The curative effect of each group was calculated and analyzed in each treated stage. RESULT: After the first stage treated in 220 pediatric chronic sinusitis, a statistical significance of curative effect could be observed between group A and B, A and B1, A and B2, A and C (P < 0.01), but none between group B and C, B1 and B2, B1 and C, B2 and C (P > 0.01). Ninety-four patients in group B were accepted the second stage treated: adenoidectomy after first treatment failed. There was a statistical significance of curative effect between group B1 and B2 (P < 0.01). Once the above management both failed, endoscopic sinus surgery (FESS) was carried out. The total effective rate of FESS was 89.65%. CONCLUSION The systemic, disciplinary medical management has some referred value in the treatment for children with chronic sinusitis. Adenoid hypertrophy and nasal cavity structural abnormalities are two relative factors of the curative effect in pediatric chronic sinusitis. The time and cost of therapy can be saved if adenoidectomy and FESS are done for cases with adenoid hypertrophy or (and) nasal cavity structural abnormalities with the systemic, disciplinary medical management simultaneously.

This article reviews the impacts of the oral health knowledge level, behavior habits, gender, socioeconomic status, and other factors related to grandparenting on children s oral health, in order to reduce the negative impact of grandparenting involvement on children s oral health, and to provide theoretical basis and guidance.

Objective:To investigate the epidemiology of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in patients with maintenance hemodialysis (MHD) in Jiangsu province during SARS-CoV-2 pandemic in China from December 7, 2022 to January 27, 2023, and to analyze the influencing factors of all-cause death.Methods:It was a multi-center cross-sectional investigation. Structured questionnaire was used to collect patient information by medical staff of each hemodialysis center (room) as investigators. Part of the demography data and laboratory examination data came from the Jiangsu Province Hemodialysis Data Information System. MHD patients from hemodialysis centers (rooms) at all levels of medical institutions and independent hemodialysis institutions in Jiangsu province during the outbreak of SARS-CoV-2 infection were included, and the clinical characteristics and all-cause mortality of confirmed and suspected cases of SARS-CoV-2 infection were analyzed.Results:Questionnaire surveys and data analysis on 57 278 patients in 407 hemodialysis centers (rooms) were completed, accounting for 90.41% of the total number of MHD patients (63 357 cases) in Jiangsu province during the same period. There were 24 038 cases (41.97%) of SARS-CoV-2 infection and 14 805 cases (25.85%) of suspected infection, which were widely distributed in all dialysis centers in Jiangsu province. After clinical classification of 38 843 confirmed and suspected SARS-CoV-2 infection cases, 3 662 cases were severe and critical cases, accounting for 9.43% of the infected and suspected cases. Among the patients who had completed the questionnaires, there were 1 812 all-cause deaths, with an all-cause mortality rate of 3.16%. Multivariate logistic regression analysis showed that elderly (taking ≤50 years as a reference, 51-59 years: OR=1.583, 95% CI 1.279-1.933, P=0.001; 60-69 years: OR=3.972, 95% CI 3.271-4.858, P<0.001; 70-79 years: OR=7.236, 95% CI 5.917-8.698, P<0.001; ≥80 years: OR=11.738, 95% CI 9.459-14.663, P<0.001), male ( OR=1.371, 95% CI 1.229-1.529, P<0.001), and co-infection with hepatitis B virus (HBV) (positive serum HBV surface antigen, OR=0.629, 95% CI 0.484-0.817, P<0.001) were independent influencing factors for all cause mortality. Receiver-operating characteristic curve analysis showed that the area under the curve for male, age and current HBV infection prediction of all-cause death was 0.529 ( P<0.001), 0.724 ( P<0.001) and 0.514 ( P=0.042), respectively, and the cut-off value for age prediction of all-cause death was 65.5 years old. Compared with patients without HBV infection, MHD patients with HBV infection significantly reduced the proportion of severe and critically ill patients, all-cause hospitalizations and all cause deaths when infected with SARS-CoV-2 (4.99% vs. 6.41%, χ2=6.136, P=0.013; 8.90% vs. 11.44%, χ2=11.662, P<0.001; 2.01% vs. 3.37%, χ2=10.713, P=0.001, respectively). Conclusion:The MHD patients in Jiangsu province are susceptible to SARS-CoV-2. Elderly age and male gender are independent risk factors for death in MHD patients during the epidemic, while the HBV infection may be a protective factor for death of MHD patients infected with SARS-CoV-2.

This article reviews relevant literature on the prevention and treatment of cancer with hesperidin published in the past 10 years by searching electronic databases such as China National Knowledge Infrastructure（CNKI）， Wanfang， and PubMed， and summarizes the research progress on the anticancer mechanism of hesperidin. Hesperidin has a wide range of pharmacological effects， including anti-inflammatory， antioxidant， antibacterial， antiviral， anticancer， immune-regulatory， anti-radiation， neuroprotective and cardiovascular protective properties and so on. Its anticancer mechanisms mainly include inhibiting cancer cell proliferation， promoting apoptosis， reducing angiogenesis， inhibiting invasion and migration of cancer cells， regulating immunity and autophagy， and exerting antioxidant and anti-inflammatory effects. As a broad-spectrum anticancer drug， hesperidin manifests chemo-preventive and therapeutic effects across various cancers， contingent upon its multifaceted anticancer mechanisms. Furthermore， this article summarizes the synergistic effects of hesperidin in combination with cisplatin， doxorubicin， cyclophosphamide and paclitaxel. It elucidates that hesperidin can enhance the cytotoxicity of these anticancer drugs against cancer cells while mitigating drug resistance and adverse side effects. Nonetheless， the clinical use is somewhat constrained due to its poor water solubility and limited bioavailability. Therefore， this article also outlines the current strategies for enhancing hesperidin's bioavailability， including structural modification， combination with other chemical substances， and utilization of nano drug carriers.The discovery of derivatives of hesperidin not only preserves the anticancer efficacy of hesperidin, but also effectively overcomes the shortcomings of poor water solubility and low bioavailability of hesperidin, effectively predicting the good application prospects of hesperidin and its derivatives.

Objective: To evaluate the implementation effect of the Beijing Tobacco Control Regulation. Methods: An observational study was conducted in a multi-stage randomly selected sample of 93 restaurants in Dongcheng and Chaoyang districts, Beijing. Undercover visits to the restaurants were paid by investigators at lunch or dinner time. The incidence of smoking behavior and the posters of no-smoking signs were observed, waiters were interviewed about awareness of the regulation, and comparisons with the baseline data of 6 months before and 1 month after regulation implementation were made. Results: The pasting rate of no-smoking signs was 76.3%. The awareness of the regulation in the waiters surveyed was high. The incidence rate of smoking in restaurants (29.0%) was lower than that before the regulation implementation (36.7%), but it was significantly higher than that one month after regulation implementation (14.8%). No active interventions from the restaurant staff were observed when smoking occurred. The incidence of smoking in restaurants within commercial buildings (3.3%) was significantly lower than that in non-commercial buildings (41.3%), the difference was significant (P<0.05). Conclusions The effect of the regulation weakened 3 years after implementation compared with that in 1 month after the implementation. The enforcement degree of the regulation was conflicted with pasting rate of no-smoking signs and the regulation awareness level in waiters in restaurants in Dongcheng and Chaoyang districts.
