This paper systematically reviews the current status of integrated traditional Chinese and western medicine in the treatment of Helicobacter pylori （Hp） infection， as well as recent progress in clinical and basic research both in China and internationally. It summarizes the advantages of traditional Chinese medicine （TCM） in Hp infection management， including improving Hp eradication rates， enhancing antibiotic sensitivity， reducing antimicrobial resistance， decreasing drug-related adverse effects， and ameliorating gastric mucosal lesions. These advantages are particularly evident in patients who are intolerant to bismuth-containing regimens， those with refractory Hp infection， and individuals with precancerous gastric lesions. An integrated， whole-process management approach and individualized， staged comprehensive treatment strategies combining TCM and western medicine are proposed for Hp infection. Future prevention and control of Hp infection should adopt an integrative Chinese-western medical strategy， emphasizing prevention， strengthening primary care， implementing proactive long-term monitoring， optimizing screening strategies， and advancing the development of novel technologies and mechanistic studies of Chinese herbal interventions. These efforts aim to provide a theoretical basis and practical pathways for the establishment and improvement of Hp infection prevention and control systems.

Pelvic organ prolapse (POP), whose etiology is influenced by genetic and clinical risk factors, considerably impacts women's quality of life. However, the genetic underpinnings in non-European populations and comprehensive risk models integrating genetic and clinical factors remain underexplored. This study constructed the first polygenic risk score (PRS) for POP in the Chinese population by utilizing 20 disease-associated variants from the largest existing genome-wide association study. We analyzed a discovery cohort of 576 cases and 623 controls and a validation cohort of 264 cases and 200 controls. Results showed that the case group exhibited a significantly higher PRS than the control group. Moreover, the odds ratio of the top 10% risk group was 2.6 times higher than that of the bottom 10%. A high PRS was significantly correlated with POP occurrence in women older than 50 years old and in those with one or no childbirths. As far as we know, the integrated prediction model, which combined PRS and clinical risk factors, demonstrated better predictive accuracy than other existing PRS models. This combined risk assessment model serves as a robust tool for POP risk prediction and stratification, thereby offering insights into individualized preventive measures and treatment strategies in future clinical practice.

Objective To assess knowledge,attitudes,and practices(KAP)of guardians of preschool children with re-spiratory infections and evaluate the effect of health education.Methods This study enrolled 169 guardians of pediatric inpa-tients at a tertiary hospital and implemented integrated online and offline health education as an intervention.KAP related to re-spiratory infection prevention and control were assessed before and after the intervention using questionnaires.Changes in KAP scores and factors influencing the intervention's effectiveness were analyzed.Results Before health education,69.8％of guardians achieved a passing score on the knowledge assessment,indicating limited awareness of respiratory infections among guardians.After health education,94.1％of them achieved the passing score,with significant improvements across all dimen-sions of respiratory infection-related KAP,as well as in the total score,with statistically significant differences before and after the intervention(P＜0.05).Univariate analysis revealed that the difference in knowledge scores before and after the intervention was statistically significant among guardians of different ages(P＜0.05).Conclusion Health education enhances guardians'awareness,attitudes,and behaviors regarding the prevention and control of respiratory infections in preschool children,playing a crucial role in reducing respiratory infection rates and promoting children's health.

Objective To analyze the diagnosis cases of occupational benzene poisoning in gas station industry, and to explore the application of GC-MS technology in occupational disease diagnosis.   Methods The epidemiological method was used to describe and analyze the occupational disease diagnosis of 15 gas station workers , and qualitative screening of occupational hazard factors was performed by GC-MS.   Results All the 15 workers had more than one year's occupation history of oil refueling and unloading.  The clinical manifestations were consistent with the characteristics of chronic benzene poisoning in diagnosis of occupational benzene poisoning.  However, due to lack of evidence of occupational exposure to benzene and incomplete diagnostic data, occupational chronic benzene poisoning was not diagnosed. GC-MS technology was used to screen the occupational hazard factors in the gas station workplace, and benzene, n-pentane, n-hexane and so on were found.  Conclusion GC-MS is recommended for qualitative screening of organic solvents such as benzene when diagnosing occupational diseases for gas station workers , so as to accurately identify occupational hazard factors in workplaces and provide reliable basis for diagnosis of occupational diseases.

OBJECTIVE To compare the efficacy and safety of icotinib and gefitinib in the treatment of epidermal growth factor receptor （EGFR）-mutated advanced non-small cell lung cancer （NSCLC）. METHODS The data of 146 patients with EGFR- mutant advanced NSCLC of our Hospital from December 2015 to September 2021 were retrospectively analyzed and divided into the gefitinib group （73 cases） and the icotinib group （73 cases） according to the drug use. Patients in the gefitinib group were given 0.25 g of gefitinib tablets once a day orally by single drug or combined with conventional chemotherapy， while patients in the icotinib group were given 125 mg of icotinib hydrochloride tablets three times a day orally by single drug or combined with conventional chemotherapy. Short-term efficacy， progression-free survival （PFS） were observed； Cox regression model was used to analyze the factors affecting the prognosis of patients； the occurrence of ADR were observed in the two groups. RESULTS There was no statistically significant difference in the objective remission rate， disease control rate， and the incidence of grade 1-2 and grade 3-4 adverse drug reactions between the two groups （P＞0.05）； median PFS was significantly better in the icotinib group than in the gefitinib group （P＝0.048）. Results of subgroup analysis based on patients basic information showed that compared with the gefitinib group， PFS of female [HR＝0.57，95%CI（0.34，0.96），P＝0.031] and non-brain metastatic patients [HR＝0.58，95%CI（0.36，0.91），P＝0.017] in icotinib group were prolonged significantly. Results of regression model analysis showed that EGFR19 exon Del mutation [HR＝0.50， 95%CI（0.25，1.00）， P＝0.049]， EGFR21 exon L858R mutation [HR＝0.44， 95%CI（0.21，0.89）， P＝0.022] and icotinib treatment [HR＝0.65， 95%CI （0.44，0.96）， P＝0.030] were influential factors for prognosis. CONCLUSIONS The short-term efficacy and safety of icotinib and gefitinib in the treatment of EGFR- mutant advanced NSCLC are comparable， but icotinib can significantly prolong the patients’ PFS； EGFR19 exon Del， EGFR21 exon L858R mutations and icotinib treatment are factors affecting patients’ prognosis.

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.

Objective To analyze the epidemiological characteristics of newly diagnosed occupational pneumoconiosis (hereinafter referred to as "pneumoconiosis") in Guangdong Province from 2011 to 2020. Methods Clinical data of newly diagnosed pneumoconiosis in Guangdong Province from 2011 to 2020 was collected from the “Health Hazards Monitoring Information System” under “China Disease Prevention and Control Information System”. The distribution of the cases was analyzed retrospectively. Results A total of 2 731 cases of newly diagnosed pneumoconiosis were reported from 2011 to 2020 in Guangdong Province, with cases at stages Ⅰ,Ⅱ, and Ⅲ accounting for 61.6%, 23.8%, and 14.6%, respectively. Except for talc pneumoconiosis, 12 other types of pneumoconiosis were reported. The top three incidence of diseases were silicosis, other pneumoconiosis, and welder's pneumoconiosis, accounting for 58.8%, 22.0% and 11.0%, respectively. Males accounted for 97.5%, and females 2.5%. The median age of onset was 47 years old. The median dust exposure duration was 9.8 years, with 19.4% of cases having a dust exposure duration less than 5.0 years. And 80.7% of the cases were distributed in the Pearl River Delta region. The industries with the new cases were mainly the manufacturing (accounting for 69.4%), and 34.8% of cases were found in private limited liability companies. Cases in medium- and small-sized enterprises accounted for 35.7% and 34.3% respectively. Conclusion Silicosis, other pneumoconiosis, and welder's pneumoconiosis are predominant in Guangdong Province. The prevention and control of pneumoconiosis should focus on small- and medium-sized private enterprises in the concentrated manufacturing industry in the Pearl River Delta region.

Objective To investigate the clinical effect of tenofovir alafenamide fumarate (TAF) on chronic hepatitis B (CHB) patients with low-level viremia (LLV) after entecavir (ETV) treatment. Methods A total of 160 CHB patients who received ETV antiviral therapy in Wuhan Jinyintan Hospital from March 2019 to October 2020 were enrolled and divided into experimental group and control group by propensity score matching, with 80 patients in each group. The patients in the experimental group were given TAF antiviral therapy, and those in the control group were given ETV treatment; the course of treatment was 24 weeks for both groups. The two groups were compared in terms of HBV-DNA clearance rate, HBeAg clearance rate, alanine aminotransferase (ALT) level, estimated glomerular filtration rate (eGFR), FIB-4 value, liver stiffness measurement, and adverse drug reactions after treatment. The t -test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. Results After 24 weeks of treatment, compared with the control group, the experimental group had significantly higher HBV DNA clearance rate (96.25% vs 16.25%, χ 2 =104.03, P < 0.001) and HBeAg clearance rate (34.78% vs 11.90%, χ 2 =6.32, P < 0.05). Compared with the control group, the experimental group had varying degrees of improvement in ALT, eGFR, FIB-4, and liver stiffness measurement ( t =5.77, 4.21, 8.45, and 4.58, all P < 0.05), and there was no significant difference in the incidence rate of adverse drug reactions between the control group and the experimental group during treatment (7.50% vs 8.75%, P > 0.05). Conclusion For CHB patients with LLV after ETV treatment, the change to TAF antiviral therapy can effectively increase their HBV DNA clearance rate and HBeAg clearance rate, improve liver and renal function, and reduce the degree of liver fibrosis, with good safety.

Unlike healthy, non-transformed cells, the proteostasis network of cancer cells is taxed to produce proteins involved in tumor development. Cancer cells have a higher dependency on molecular chaperones to maintain proteostasis. The chaperonin T-complex protein ring complex (TRiC) contains eight paralogous subunits (CCT1-8), and assists the folding of as many as 10% of cytosolic proteome. TRiC is essential for the progression of some cancers, but the roles of TRiC subunits in osteosarcoma remain to be explored. Here, we show that CCT4/TRiC is significantly correlated in human osteosarcoma, and plays a critical role in osteosarcoma cell survival. We identify a compound anticarin-β that can specifically bind to and inhibit CCT4. Anticarin-β shows higher selectivity in cancer cells than in normal cells. Mechanistically, anticarin-β potently impedes CCT4-mediated STAT3 maturation. Anticarin-β displays remarkable antitumor efficacy in orthotopic and patient-derived xenograft models of osteosarcoma. Collectively, our data uncover a key role of CCT4 in osteosarcoma, and propose a promising treatment strategy for osteosarcoma by disrupting CCT4 and proteostasis.

Objective:To analysis the expression of CD7 in NK/T-cell lymphoma as well as study the correlations between CD7 and clinical survival and prognosis.Methods:The clinical and pathological indicators of 112 NKTCL patients who were admitted to or consulted at the First Affiliated Hospital of Zhengzhou University between May 2008 and December 2019 were analyzed retrospectively. The CD7 expression in the tumor tissues was detected using immunohistochemistry staining, and the influence of CD7 expression on the survival and prognosis in the patients was analyzed.Results:The CD7 expression rate was 84.82% in 112 NKTCL patients, and its expression was not influenced by sex, age, and the primary site. An analysis of the complete clinical data of 72 patients showed that the CD7 expression was significantly correlated with the PINK score, tumor metastasis, and peripheral blood EBV-DNA level. However, the Ann Arbor stage, bone marrow involvement, B symptoms, IPI/aaIPI score, Ki-67, EBER, TIA-1, Granzyme B, LDH, and β 2-MG were not associated with the CD7 expression. The 1-year, 3-year, and 5-year overall survival (OS) rates of the 72 patients were 81.2%, 61.8%, and 58.8%, respectively, and the progression-free survival (PFS) rates were 53.5%, 29.4%, and 24.0%, respectively. The median overall survival (median-OS, mOS) was 81 mon, and the median progression-free survival (median-PFS, mPFS) was 14 mon. The 3-year OS rates in the CD7-positive group and the CD7-negative group were 58.1% and 83.9%, respectively, ( P>0.05) . The 3-year PFS rates were 21.7% and 51.9%, respectively ( P<0.05) . The univariate analysis showed that age, primary tumor site, Ann Arbor stage, IPI/aaIPI score, PINK score, LDH, β 2-microglobulin, EBV-DNA, Ki-67, and CD7 influenced patient prognosis. The multivariate analysis showed that Ann Arbor stage and CD7 were independent prognostic factors for PFS, while PINK score and Ki-67 were independent prognostic factors for OS. Conclusions:The expression rate of CD7 in NKTCL was high and was closely related to poor patient prognosis. The patients with high levels of EBV-DNA, metastatic disease, or high PINK score were more likely to express CD7.
