OBJECTIVE: To identify prognostic genes associated with lysosome-dependent cell death (LDCD) in patients with gastric cancer (GC). METHODS: Differentially expressed genes (DEGs) were identified using The Cancer Genome Atlas - Stomach Adenocarcinoma. Weighted gene co-expression network analysis was performed to identify the key module genes associated with LDCD score. Candidate genes were identified by DEGs and key module genes. Univariate Cox regression analysis, and least absolute shrinkage and selection operator regression and multivariate Cox regression analyses were performed for the selection of prognostic genes, and risk module was established. Subsequently, key cells were identified in the single-cell dataset (GSE183904), and prognostic gene expression was analyzed. Cell proliferation and migration were assessed using the Cell Counting Kit-8 assay and the wound healing assay. RESULTS: A total of 4,465 DEGs, 95 candidate genes, and 4 prognostic genes, including C19orf59, BATF2, TNFAIP2, and TNFSF18, were identified in the analysis. Receiver operating characteristic curves indicated the excellent predictive power of the risk model. Three key cell types (B cells, chief cells, and endothelial/pericyte cells) were identified in the GSE183904 dataset. C19orf59 and TNFAIP2 exhibited predominant expression in macrophage species, whereas TNFAIP2 evolved over time in endothelial/pericyte cells and chief cells. Functional experiments confirmed that interfering with C19orf59 inhibited proliferation and migration in GC cells. CONCLUSION C19orf59, BATF2, TNFAIP2, and TNFSF18 are prognostic genes associated with LDCD in GC. Furthermore, the risk model established in this study showed robust predictive power.

Objective To investigate the efficacy of flupentixol combined with ondansetron in preventing postoperative nausea and vomiting(PONV)in patients receiving sufentanil and dezocine patient-controlled intravenous analgesia(PCIA).Methods Surgical patients receiving sufentanil and dezocine PCIA were randomly divided into treatment and control groups using a random number table.The control group received sufentanil 150 μg,dezocine 20 mg,and ondansetron 8 mg for PCIA,while the treatment group received sufentanil 150 μg,dezocine 20 mg,flupentixol 5 mg,and ondansetron 8 mg for PCIA.The incidence of PONV,severity of PONV,heart rate(HR),mean arterial pressure(MAP),blood oxygen saturation(SPO2)levels at different time points after surgery,surgery-related indicators,visual analogue scale(VAS)scores,Ramsay scores,PCIA pressing times,and incidence of adverse drug reactions were compared between the two groups.Results The incidence of PONV in the treatment group and the control group at 2,12,24,36 and 48 hours after surgery were 1.64％,4.84％,6.56％,3.28％,0 and 14.75％,18.03％,19.67％,16.39％,9.84％,respectively.The HR at 24 hours after surgery in the treatment group and the control group were(91.42±8.75)and(98.13±9.62)beat·min-1,respectively;the MAP were(91.98±4.56)and(99.05±4.17)mmHg;SPO2 were(98.13±1.65)％and(98.95±1.82)％;VAS scores were 2.68±0.49 and 2.97±0.63;Ramsay scores were 2.27±0.65 and 2.05±0.32;PCIA pressing times were(2.14±0.37)and(4.36±0.78)times,respectively.The differences in the above indicators between the treatment group and the control group were statistically significant(all P＜0.05).The incidence of total adverse drug reactions after surgery in the treatment group and the control group were 13.12％and 8.20％,respectively,with no statistically significant difference(P＞0.05).Conclusion Flupentixol combined with ondansetron can reduce the risk of PONV caused by sufentanil combined with dezocine PCIA after surgery,ensuring good analgesic effects and safety.

Standardized reporting is a crucial factor affecting the use of patient guidelines （PGs）， particularly in the reporting and presentation of recommendations. This paper introduced the current status of PG reporting， including the research on PG content and presentation formats， and provided comprehensive recommendations for PG reporting from aspects such as overall framework， recommendations， presentation format， and readability. First， the presentation of PG recommendations should include clearly defined clinical questions， recommendations and their rationale， and guidance on how patients should implement the interventions； for specific content in the PG， such as level of evidence， level of recommendation， it is recommended to explain in text the reasons for giving different levels of recommendation， i.e.， to present the logic behind giving the level of recommendation to the patient； additional information needed in the recommendation framework should be supplemented by tracing references or authoritative textbooks and literature that support the recommendations. Subsequently， the PG text should be written based on the Reporting Checklist for Public Versions of Guidelines （RIGHT-PVG） reporting framework. Finally， to enhance readability and comprehension， it is recommended to refer to the Patient Education Materials Assessment Tool （PEMAT） for translating PG content. To enhance the readability of PGs， it is suggested to present the PG content in a persona-lized and layered manner.

Objective To investigate the basic conditions of non-medical radiation institutions and their current status of occupational health management of radiation workers and radiation protection in workplaces in Tianjin City, China, and to clarify the key points of occupational health management and radiation protection efforts. Methods A comprehensive survey was conducted to assess the basic conditions of non-medical radiation institutions and their status of occupational health management for radiation workers across 16 districts in Tianjin in 2023. Then, some non-medical radiation institutions were chosen according to their industrial sections as sentinel institutions to investigate radiation protection in workplaces. Results In 2023, there were a total of 431 non-medical radiation institutions in 16 districts of Tianjin, primarily in the industries of nuclear instrument, industrial radiography, and others. In these institutions, there were a total of 5264 radiation workers, with 93.8%, 93.0%, and 93.7% participating in the training of radiation protection, the occupational health examination, and the personal dose monitoring, respectively. Eighty-six non-medical radiation institutions were chosen as the sentinel institutions for investigation of radiation protection conditions in workplaces. The resulting data met the stipulated limits according to relevant standards. Conclusion The current status of occupational health management and radiation protection in non-medical radiation institutions in Tianjin is satisfactory. However, there is a need for further management enhancements, particularly in key industries such as nuclear instrumentation and industrial radiography.

Since the concept of patient versions of guidelines （PVGs） was introduced into China， several PVGs have been published in China， but we found that there is a big difference between the concept of PVG at home and abroad， and the reason for this difference has not been reasonably explained， which has led to ambiguity and even misapplication of the PVG concept by guideline developers. By analyzing the background and purpose of PVGs， and the understanding of the PVG concept by domestic scholars， we proposed the term patient guidelines （PGs）. This refers to guidelines developed under the principles of evidence-based medicine， centered on health issues that concern patients， and based on the best available evidence， intended for patient use. Except for the general attribute of providing information or education， which is typical of common health education materials， PGs also provide recommendations and assist in decision-making， so PGs include both the patient versions of guidelines （PVG） as defined by the Guidelines International Network （GIN） and "patient-directed guidelines"， i.e. clinical practice guidelines resulting from the adaptation or reformulation of recommendations through clinical practice guidelines.

At present， the process and methodology of patient guidelines （PGs） development varies greatly and lacks systematic and standardised guidance. In addition to the interviews with PG developers， we have sorted out the relevant methodology for the adaptation and development of existing clinical practice guideline recommendations and facilitated expert deliberations to achieve a consensus， so as to finally put forward a proposal for guidance on the process and methodology for the development of PGs. The development of PGs can be divided into the preparation stage， the construction stage， and the completion stage in general， but the specific steps vary according to the different modes of development of PGs. The development process of Model 1 is basically the same as the patient version of the guideline development process provided by the International Guidelines Network， i.e.， team formation， screening of recommendations， guideline drafing， user testing and feedback， approval and dissemination. The developer should also first determine the need for and scope of translating the clinical practice guideline into a patient version during the preparation phase. Model 2 adds user experience and feedback to the conventional clinical practice guideline development process （forming a team， determining the scope of the PG， searching， evaluating and integrating evidence， forming recommendations， writing the guideline， and expert review）. Based on the different models， we sort out the process and methods of PG development and introduce the specific methods of PG development， including how to identify the clinical problem and how to form recommendations based on the existing clinical practice guidelines， with a view to providing reference for guideline developers and related researchers.

BACKGROUND:Host immune response triggered by plaque biofilm is an initiator of periodontitis progression and destruction.Macrophages are an important component of the innate immune response,which play an important role in inflammation occurrence and development. OBJECTIVE:To review the relationship between macrophage polarization and periodontitis and the related progress in the treatment of periodontitis by regulating macrophage polarization. METHODS:PubMed and CNKI databases were searched for relevant literature published from 1990 to 2023,with"macrophage polarization,M1/M2 macrophage,periodontitis,periodontitis treatment,macrophage polarization and periodontitis,osteoimmunology,ferroptosis,macrophage polarization and ferroptosis,periodontitis and ferroptosis"as the English and Chinese search terms.After the initial screening,96 articles were selected for review. RESULTS AND CONCLUSION:The switch between different phenotypes of macrophages is closely related to the tissue destruction caused by periodontitis,and various cytokines and inflammatory mediators secreted from macrophages are involved in the destruction and repair of periodontal tissue.Therefore,regulation of macrophage polarization and cytokine secretion in inflammatory state helps to alleviate periodontitis inflammation and improve the periodontal microenvironment,thereby reducing tissue destruction or promoting periodontal tissue regeneration.Many studies have been conducted to develop drugs or biomaterials to modulate macrophage function for the purpose of immunomodulatory treatment of periodontitis.However,macrophages act throughout the development of periodontitis and play an important role in the process of anti-infection,bone destruction and bone repair,and polarization is a complex and dynamic process influenced by many factors.Therefore,further exploration on possible mechanisms is still needed to clarify the interaction between materials or drugs and macrophages.

Objective To understand the HIV/AIDS burden and the disease burden attributed to various risk factors in four countries with different socio-demographic index (SDI) (China, United States, Russia, and Afghanistan) from 1990 to 2019, and to predict the HIV/AIDS attributable disease burden from 2020 to 2029. Methods The 2019 Global Burden of Disease Study data was used to describe and compare the incidence, prevalence, death, and DALYs of HIV/AIDS in the four countries. The standardized DALYs attributed to various risk factors in different age groups of HIV/AIDS in the four countries in 1990 and 2019 were compared. R4.3.0 was used to construct an autoregressive moving average mixed model to predict the attributable disease burden in each country over the next decade. Results Compared with 1990, in 2019, the standardized incidence rate, standardized prevalence rate, standardized mortality rate, and standardized DALYs rate in China and the other two countries, except the United States, showed an increase. People aged 10 to 49 years old were a key group for disease burden, and the main risk factors for disease burden varied among different countries and age groups. The autoregressive moving average mixed model predicted that the main risk factor for Russia in the next decade would be injecting drugs, while unsafe sexual behavior would occur in the other three countries. Conclusion There are differences in disease burden and risk factors among different genders and age groups globally and in the four different SDI countries. Therefore, differences should be fully considered to determine the focus of HIV/AIDS prevention and control and rationally allocate health resources.

Objective To investigate the relationship between the expression of long non-coding RNA HOXA-AS2(lncRNA HOXA-AS2),long non-coding RNA FOXD2-AS1(lncRNA FOXD2-AS1),and long non-coding RNA CRNDE(lncRNA CRNDE)in endometrial carcinoma and the clinical pathological character-istics and prognosis of patients.Methods Collect samples of endometrial carcinoma cancer tissues and adja-cent tissues excised during surgery from 119 endometrial carcinoma patients admitted to a hospital from Octo-ber 2017 to February 2020.The relative expression levels of HOXA-AS2,FOXD2-AS1 and CRNDE in tissues were retrospectively analyzed,as well as their relationship with clinicopathological features and 3-year survival rate of patients.Results The relative expression levels of HOXA-AS2,FOXD2-AS1 and CRNDE in cancer tissues of endometrial carcinoma patients were higher than those in adjacent tissues,with statistical signifi-cance(P＜0.05).The relative expression levels of HOXA-AS2,FOXD2-AS1 and CRNDE in cancer tissues of endometrial carcinoma patients were positively correlated(rHOXA-As2 vs.FOXD2-AS1=0.384,P=0.001;rHoXA-AS2 vs.CRNDE=0.576,P＜0.001;rFoXD2-AS1 vs.CRNDE=0.326,P=0.003).In the HOXA-AS2,FOXD2-AS1 and CRNDE high expression group,the proportion of patients with international federation of gynecology and ob-stetrics(FIGO)stage Ⅲ+Ⅳ,lymph node metastasis,deep infiltration and low differentiation was higher than that in the low expression group,with statistical significance(P＜0.05).The 3-year survival rate of low HOXA-AS2 expression group in endometrial cancer patients(52/60,86.67％)was higher than that of high HOXA-AS2 expression group(40/59,67.79％),the difference was statistically significant(x2=6.039,P＜0.05).The 3-year survival rate of patients with endometrial cancer with low FOXD2-AS1 expression group(53/59,89.83％)was higher than that of patients with endometrial cancer with high FOXD2-AS1 expression group(39/60,65.00％),and the difference was statistically significant(x2=10.456,P＜0.05).The 3-year sur-vival rate of low CRNDE expression group in endometrial cancer patients(51/60,85.00％)was higher than that of high CRNDE expression group(41/59,69.49％),and the difference was statistically significant(x2=4.079,P＜0.05).HOXA-AS2,FOXD2-AS1,and CRNDE were risk factors for death in endometrial carcinoma patients(P＜0.05).Conclusion The expression of HOXA-AS2,FOXD2-AS1,and CRNDE in endometrial carcinoma cancer tissue is closely related to the clinical pathological characteristics and prognosis of patients.
