Objective To evaluate the occupational health literacy (OHL) level and its influencing factors among individuals of six key industries from Jiulongpo District, Chongqing City. Methods A total of 2 022 frontline workers from six key industries in the Jiulongpo District of Chongqing City were selected as the research subjects using a cluster sampling method. The OHL level of the workers were assessed using the Occupational Health Literacy Questionnaire of National Key Populations. Results The overall OHL level among the 2 022 frontline workers was 51.43%. The OHL level in the four dimensions of basic knowledge of occupational health protection, healthy work practices and behaviors, legal knowledge of occupational health, and basic skills of occupational health protection were 81.45%, 56.08%, 43.42%, and 37.59%, respectively. The OHL levels of the six key industries from high to low were electrical machinery and equipment manufacturing, healthcare, education, express delivery/food delivery, transportation, and environmental hygiene, accounted for 91.43%, 61.98%, 52.64%, 40.58%, 36.70% and 31.15% (P<0.01). The results of logistic regression analysis showed that population of Han had higher OHL level than ethnic minorities (P<0.01), married individuals had lower OHL level than unmarried individuals (P<0.05), individuals with college education or above had higher OHL level than those with junior high school education or below (P<0.01), and higher personal monthly income was associated with higher OHL levels (all P<0.05). The OHL levels of workers of environmental hygiene, transportation, education, express delivery/food delivery, and healthcare were lower than those in electrical machinery and equipment manufacturing (all P<0.01). Conclusion The OHL level among occupational populations in the six key industries in Jiulongpo District, Chongqing City, needs to be further improved. And the OHL monitoring and intervention should be focused on the occupational population of express delivery/food delivery industry, transportation, environmental hygiene, and occupational population with low income, low educated, and ethnic minorities.

OBJECTIVE To compare the efficacy and safety of Cefazolin sodium for injection， Cefuroxime sodium for injection， and Ceftazidime for injection from nationally organized centralized drug procurement （hereinafter referred to as “centralized procurement”） and non-centralized procurement in patients with bacterial infection. METHODS The case data of hospitalized patients who had used 3 kinds of Cephalosporins for injection from centralized procurement or non-centralized procurement in the treatment of bacterial infections were retrospectively collected from 19 medical institutions in Kunming from January 2020 to September 2022. After balancing the baseline differences between the groups with the propensity score matching method， the effectiveness and safety differences of 3 kinds of Cephalosporins for injection from centralized procurement or non- centralized procurement were compared respectively. RESULTS After balancing the baseline differences among the groups， 394 cases in each group of Cefazolin sodium for injection from centralized procurement or non-centralized procurement， 472 cases in each group of Cefuroxime sodium for injection from centralized procurement or non-centralized procurement， 504 cases in group of Ceftazidime for injection from centralized procurement and 590 cases in group of non-centralized procurement were included in the analysis. In terms of effectiveness， there were no significant differences in clinical response rate， 72 h response rate， bacterial clearance rate， and the recovery rate of body temperature， white blood cell count， neutrophil count， neutrophil percentage， C-reactive protein， procalcitonin recovery between the centralized procurement group and non-centralized procurement group of Cefazolin sodium for injection and Cefuroxime sodium for injection （P＞0.05）. The proportion of patients in centralized procurement group of Ceftazidime for injection with C-reactive protein restored to normal reference range was significantly higher than that in non-centralized procurement group （46.9% vs. 27.9%， P＜0.05）， but there were no statistically significant differences in other effectiveness indicators among groups （P＞0.05）. In terms of safety， there was no statistical difference in the incidence of adverse drug reactions between centralized procurement group and non-centralized procurement group of 3 kinds of Cephalosporins for injection （P＞0.05）； the incidence of platelet count reduction in centralized procurement group of Cefazolin sodium for injection was significantly higher than non-centralized procurement group （20.7% vs. 7.1%， P＜0.05）， the incidence of eosinophilia elevation in centralized procurement group of Ceftazidime for injection was significantly higher than non-centralized procurement group （5.3% vs. 1.9%， P＜0.05）. In addition， there was no statistically significant difference in the abnormal rates of other laboratory indicators among the three types of injection Cephalosporins （P＞ 0.05）. CONCLUSIONS The efficacy of 3 kinds of Cephalosporin for injection from centralized procurement is not inferior to non- centralized procurement varieties， and the safety is equivalent to that of non-centralized procurement varieties.

Objective:To conduct a multidimensional quantification and analysis of the development trajectory of both "quality" and "quantity" in China's higher education from 2001 to 2021, and lay a solid foundation for the construction of a high-quality education system.Methods:Based on macro statistical data on education in China from 2001 to 2021, a comprehensive indicator system for the development level of higher education was established. This system included six dimensions: educational conditions, financial support, institutional safeguards, scientific research, social services, and international collaboration. Methods such as entropy-weighted TOPSIS, general difference index, spatial autocorrelation, and hot spot analysis were used to evaluate the level of high-quality development of higher education and its spatial differentiation. Additionally, an obstacle degree analysis model was used to evaluate the factors hindering the high-quality development of higher education.Results:The high-quality development level of China's higher education has steadily improved, with a growth rate of 2.85%. The spatial distribution exhibited a clustering pattern, with stable hotspot regions established in the eastern region characterized by significant "spillover" effects. Concurrently, the western regions narrowed the development gap compared with other areas. Scientific research represents the primary challenge to achieving high-quality development in higher education, with an average obstacle degree of 18.46%. Books per student, fixed assets per student, foreign technology imported per institution, research & development project funds, research & development projects per institution, and personnel investment in research & development projects were important constraints on the development of higher education in China and the provinces.Conclusions:Resource sharing and linkage need to be guaranteed by policy and institutional support, and each subject of higher education should give full play to its own advantages to contribute to the high-quality development of higher education through interregional linkage development, mutual synergy, and common progress.

Biliary atresia is a rare infant disease that predisposes patients to liver transplantation and death if not treated in time. However, early diagnosis is challenging because the clinical manifestations and laboratory tests of biliary atresia overlap with other cholestatic diseases. Therefore, it is very important to develop a simple, safe and reliable method for the early diagnosis of biliary atresia. Herein, a novel NIR-II fluorescence probe, HZL2, with high quantum yield, excellent biocompatibility, low cytotoxicity and rapid excretion through the liver and gallbladder was developed based on the oil/water partition coefficient and permeability. A simple fecal sample after injection of HZL2 can be used to efficiently identify the success of the mouse model of biliary atresia for the first time, allowing for an early diagnosis of the disease. This study not only developed a simple and safe method for the early diagnosis of biliary atresia with great potential in clinical translation but also provides a research tool for the development of pathogenesis and therapeutic medicines for biliary atresia.

Objective To investigate the correlation between serum levels of antiphospholipid antibody(aPL)(ACA-IgG,ACA-IgM,β2-GPI-IgG,β2-GPI-IgM),LAC,ds-DNA,and ANA and preterm labor with pre-maturity,and to analyze the prediction of preterm labor with the combination of age,week of gestation,history of delivery,and history of miscarriage,so as to provide references for the prevention and treatment of preterm la-bor and to promote eugenics.Methods Through a retrospective study design,43 pregnant women with preterm la-bor with preeclampsia diagnosed and treated at Guangdong Provincial People's Hospital from June 2018 to Decem-ber 2020 were collected as a case group,and 47 healthy pregnant women of the same period and similar gestational age were randomly selected as a control group.aPL(ACA-IgG,ACA-IgM,β2-GPI-IgG,β2-GPI-IgM)and ds-DNA were detected by enzyme immunoassay(ELISA)using an enzyme immunoassay instrument,lupus anticoagulant(LAC)in plasma was detected by coagulometer,and ANA was detected by indirect immunofluorescence using an immunofluorescence analyzer,and the application of SPSS 24.0 software was used to statistically analyze the gen-eral information and laboratory test data.the age of the patients was combined,gestational week,birth history,miscarriage history and other general information,logistic regression analysis was performed to find the indepen-dent influencing factors related to preterm labor;the analysis was performed by using the subjects'work charac-teristic curve(ROC curve)to determine the area under the ROC curve(AUC),the best predictive value,sensi-tivity and specificity,and to analyze the predictive value of preterm labor with preterm labor.Results In this study,the pregnant women in the group of pregnant women with preterm labor with preeclampsia were aged 27～40 years,with a mean age of(29.93±3.91)years,and the gestational weeks at the time of blood collection were 27-36 weeks,with a mean gestational week of(31.96±2.35)weeks,while the pregnant women in the healthy control group during the same time period were aged 25～40 years,with a mean age of(30.74±3.44)years,and the gestational weeks at the time of blood collection were 28～36 weeks,with a mean gestational week of(32.84±2.13)weeks.In the same period,healthy control group pregnant women were aged 25～40 years,with a mean age of(30.74±3.44)years,and were 28～36 weeks pregnant at the time of blood collection.The β2-GPI-IgM level of pregnant women in the case group with preterm labor was significantly higher than that of pregnant women in the healthy control group at the same time,with statistically significant differences(P<0.05),while the differences in the levels of β2-GPI-IgG,ds-DNA,and LAC between the two groups were not statistically significant(P>0.05).The analysis of the ROC curves showed that the AUC of β2-GPI-IgM was 0.642(P<0.05),which was the highest in the preterm group,and the AUC was 0.642(P<0.05).0.05),which was an independent influencing factor of preterm labor;age,gestational week,labor history,and miscarriage history could not be used as independent in-fluencing factors of preterm labor.Conclusion β2-GPI-IgM is associated with threatened preterm labor,it can be used as a predictor of threatened preterm labor,and has clinical utility in the monitoring of threatened preterm labor in pregnant women.

Objective:To explore the predictive value of exhaled nitric oxide (FeNO) for the risk of acute exacerbation in stable chronic obstructive pulmonary disease (COPD) patients over the next year and evaluate whether it can guide the use of inhaled corticosteroids (ICS).Methods:This study was a multicenter, retrospective and observational cohort study. The subjects of this study were stable COPD patients who were hospitalized in 12 hospitals in Hunan Province and Guangxi from January 2017 to December 2021. The patient′s basic Demography information, previous acute exacerbation history, pulmonary function, FeNO, chronic obstructive pulmonary disease assessment test questionnaire (CAT) score, modified British Medical Research Council dyspnea questionnaire (mMRC) score, chronic obstructive pulmonary disease control questionnaire (CCQ) score, and detailed treatment plan were collected. Based on FeNO 25 ppb, patients were divided into a high FeNO group and a normal FeNO group. All patients were followed up for 1 year and information on acute exacerbation was recorded.Results:A total of 825 patients were included, aged (63.5±9.1)years, with a median of 25 ppb of FeNO. A number of 825 patients were followed up for 1 year, of which 262(31.8%) experienced acute exacerbation. Multivariate logistic regression found that FeNO, CAT score, smoking cessation, and past history of acute exacerbation were independent factors predicting acute exacerbation in COPD patients in the next year (all P<0.05). High FeNO was a protective factor for acute exacerbation in COPD patients in the next year, with an OR value of 0.10 ( P<0.001). Further analysis found that the proportion of patients in the high FeNO group using ICS was significantly higher than that in the normal FeNO group [58.8%(247/420) vs 48.6%(197/405), P=0.003]. In the high FeNO group, using ICS can reduce the incidence of acute exacerbation of COPD in the next year [8.9%(22/247) vs 15.6%(27/173), P<0.05], while in the normal FeNO group, there was no statistically significant difference in the frequency of acute exacerbation between patients using ICS and those not using ICS ( P>0.05). Conclusions:FeNO is an independent factor predicting the acute exacerbation of COPD in the next year, and patients with high FeNO levels may consider using ICS in combination.

Peripheral T-cell lymphoma (PTCL) is a highly heterogeneous disease with numerous subtypes, and the overall prognosis is poor, especially in relapsed/refractory patients, and the patients are generally older with limited treatment options that can be tolerated. At the 64th American Society of Hematology (ASH) Annual Meeting in 2022, studies on relapsed/refractory PTCL include the combination of epigenetic agents or combination of immune checkpoint inhibitors, CD30 antibody-drug conjugate (ADC) brentuximab vedotin combined with chemotherapy, targeted drugs PI3K inhibitors and JAK1 inhibitors, etc., providing more choices and opportunities for relapsed/refractory patients.

Objective:To conduct a comparative analysis of the efficacy, safety, and cytokine changes associated with three distinct dose escalation regimens of allergen-specific immunotherapy (AIT), and to provide valuable insights into the implementation of safer and more effective accelerated immunotherapy in clinical practice.Methods:A prospective study of subcutaneous immunotherapy (SCIT) was conducted at Renmin Hospital of Wuhan University, involving patients with allergic rhinitis visited from 2019 to 2022. Participants were allocated to one of three treatment groups based on their preferences: conventional immunotherapy (CIT, 23 cases), cluster immunotherapy (CLIT, 25 cases), or rush immunotherapy (RIT, 18 cases). The RIT group received a single subcutaneous injection of 150 mg of omalizumab one week before commencing treatment. Subjective evaluation indices, including the Combined Symptom and Medication Score (CSMS), Visual Analogue Scale (VAS), and single symptom score, were recorded alongside objective evaluation indices (e.g., sIgE, tIgE, Th1/2 and Th17 cytokines) and adverse reactions. Assessments were conducted at baseline, and at 1, 7, and 15 weeks after treatment. SPSS 22.0 software was used for data processing and analysis.Results:The study included a total of 66 patients, comprising 37 males and 29 females, who completed the treatment regimen. In all three groups, CSMS and VAS scores showed significant reductions at 1, 7, and 15 weeks post-treatment (all P<0.05). Notably, the RIT group demonstrated a significantly lower VAS score (4.33±0.94) compared to the CIT (9.48±1.37) and CLIT (9.44±1.33) groups at 1 week post-treatment ( P<0.05). Additionally, the RIT group (0.62±0.23) exhibited a lower CSMS score than the CIT (1.54±0.21) and CLIT (1.06±0.22) groups at 15 weeks post-treatment ( P<0.05). Furthermore, at the point of reaching the maintenance dose, the RIT group (0.61±0.20) demonstrated superior improvement in nasal itching symptoms compared to the CIT (1.78±0.38) and CLIT groups (1.56±0.32), with P<0.05. The incidence of local adverse reactions in the RIT group (36/11.76%) was lower than that in the CIT (69/20.00%) and CLIT groups (62/16.53%), with P<0.05. Notably, none of the three groups reported grade 3/4 systemic adverse reactions, and there was no statistically significant difference in systemic adverse reactions among the three groups. Following treatment, IL-4, IL-5, IL-6, IL-17, sIgE, sIgE/tIgE, and Eos% exhibited varying degrees of decrease in all three groups, whereas IL-10, TNF, and IFN-γ did not show significant changes. Conclusions:All three distinct dose escalation regimens of SCIT demonstrated substantial clinical efficacy. Of note, the approach of combining a single injection of omalizumab with RIT significantly improved early-stage efficacy and exhibited the advantages of safety, effectiveness, and convenience, establishing it as a reliable immunotherapy method.

Objective:To observe the clinical characteristics and guideline compliance of chronic obstructive pulmonary disease (COPD) patients with initial triple therapy in real-life world.Methods:This study is a cross-sectional study. The subjects of the study were COPD patients admitted to 13 hospitals in Hunan Province and Guangxi Zhuang Autonomous Region from December 2016 to December 2021. The initial treatment was triple inhaled drugs. The data collected included gender, age, diagnosis, body mass index (BMI), history of acute exacerbation (AE) in the past year, pulmonary function, COPD Assessment Test (CAT) score, modified British Medical Research Council Dyspnea Questionnaire (mMRC), inhaled drugs and other indicators. The characteristics and differences of COPD patients before and after 2020 were analyzed.Results:7 184 patients with COPD were enrolled in this study, including 2 409 COPD patients treated with initial triple therapy, accounting for 33.5%(2 409/7 184). Taking January 1st, 2020 as the cut-off point, 1 825 COPD patients (75.8%) received initial treatment with triple inhaled drugs before 2020 and 584 patients (24.2%) after 2020 were included in this study. Compared with COPD patients before 2020, the COPD patients after 2020 had higher FEV 1% [(40.9±15.5 )% vs (39.3±15.5)%, P=0.040], lower CAT [(15.8±6.5)point vs (17.5±6.2)point, P<0.001], less AE in the past year [1(0, 2)times vs 1(0, 2)times, P=0.001] and higher rate of non-AE [255(43.7%) vs 581(37.1%), P=0.006]. In addition, before 2020, patients with COPD were mainly treated with open triple drugs (1 825/1 825, 100%); after 2020, 306 patients (52.4%) received open triple inhaled drugs, and 278 patients (47.6%) received closed triple inhaled drugs. Conclusions:In real-life world, most of patients with COPD treated with triple therapy have severe lung function, obvious symptoms and high risk of acute exacerbation. The real-world prescribing of triple therapy in patients with COPD does not always reflect recommendations in guidelines and strategies, and overtreatment is common. After 2020, prescribing triple therapy for COPD patients is more positive and worse consistency with guideline.
