OBJECTIVE To evaluate the efficacy and safety of rituximab （RTX） in the treatment of primary Sjögren syndrome （pSS）. METHODS Randomized controlled trials （RCTs） on the effects of RTX （trial group） versus placebo （control group） in the treatment of pSS were searched from the Cochran Library， PubMed， Embase， Medline， Web of Science， VIP， CNKI， Wanfang， and other databases during the inception to February 2024. After literature screening and quality evaluation， meta-analysis was performed by using RevMan 5.3 software. RESULTS Seven RCTs were finally included， involving a total of 518 patients. Results of meta-analysis showed that European League Against Rheumatism Sjögren syndrome disease activity index （ESSDAI） score [MD＝－1.17， 95%CI（－1.52， －0.82）， P＜0.000 01] and oral dryness visual analogue scale （VAS） score [MD＝－3.97， 95%CI （－5.08， －2.86）， P＜0.000 01] in the trial group were significantly lower than the control group； unstimulated salivary flow rate [SMD＝0.64， 95%CI（0.41， 0.87）， P＜0.000 01] and Schirmer score [MD＝0.19， 95%CI（0.18， 0.20）， P＜0.000 01] were significantly higher than the control group. There was no statistical significance in response rate [RD＝0.10， 95%CI（－0.04， 0.23）， P＝0.16]， fatigue VAS score [MD＝－12.50， 95%CI（－35.14， 10.15）， P＝0.28]， European League Against Rheumatism Sjögren syndrome patient reported index （ESSPRI） score [MD＝0.33， 95%CI（－0.53， 1.18）， P＝0.46]， Short-form 36 health survey physical component summary （SF36-PCS） score [MD＝0.90， 95%CI（－2.97， 4.78）， P＝0.65]， SF-36 mental component summary （SF36-MCS） score [MD＝0.11， 95%CI（－0.41， 0.63）， P＝0.68]， total salivary gland ultrasound score [SMD＝－1.91， 95%CI（－4.01， 0.19）， P＝0.07] or the incidence of adverse drug reactions [OR＝1.15，95%CI（0.62，2.13），P＝0.66] between 2 groups. CONCLUSIONS RTX has advantages in the improvement of ESSDAI score， unstimulated salivary flow rate， Schirmer score and oral dryness VAS score in pSS patients， and has a good safety profile. However， it did not exhibit significant improvement in fatigue VAS score， ESSPRI score， SF36-PCS score， SF36-MCS score or response rates.

OBJECTIVE To analyze the influential factors for clinical efficacy of polymyxin B combined with other antibiotics in the treatment of carbapenem-resistant Acinetobacter baumannii （CRAB） pulmonary infection. METHODS A retrospective analysis was conducted on the clinical data of patients with CRAB pulmonary infection in our hospital from May 2021 to October 2024. Information such as age， gender， admitting department， infection status， underlying medical conditions， mechanical ventilation time， combination anti-infective treatment regimens， and the Acute Physiology and Chronic Health Evaluation Ⅱ （APACHE-Ⅱ） score 24 h before medication was compiled. Based on the effectiveness of the treatment， patients were divided into treatment-effective group and treatment-ineffective group. Univariate analysis and multivariate Logistic regression analysis were employed to identify independent factors influencing clinical efficacy. RESULTS A total of 156 patients were included， and 108 patients were treated effectively， with an effective rate of 69.23%. The results of univariate analysis indicated that there were statistically significant differences between 2 groups in terms of the duration of mechanical ventilation time， APACHE-Ⅱ score 24 h before medication， the number of complication types， the proportion of abnormal coagulation function， anti-infective treatment course， and hospital stay before medication （P＜0.05）. The results of multivariate Logistic regression analysis showed that APACHE-Ⅱ score≥15 points 24 h before medication [OR＝2.965， 95%CI （1.284， 6.845）， P＝0.020]， mechanical 20251606） ventilation time≥10 d [OR＝3.577， 95%CI （1.185， 10.793）， P＝0.037] and hospital stay≥14 d before medication [OR＝2.422， 95%CI （1.036， 5.654）， P＝0.041] were independent 15120420253@139.com risk factors， and anti-infective treatment course＞7 d was a protective factor [OR＝0.445， 95%CI （0.221， 0.895）， P＝0.043]. CONCLUSIONS This study shows that the effective rate of polymyxin B combined with other antibiotics in the treatment of CRAB pulmonary infection is less than 70%. The mechanical ventilation time≥10 d， APACHE-Ⅱ score≥15 points 24 h before medication， and hospital stay≥14 d before medication may lead to treatment failure， whereas anti-infective treatment course＞7 d may be associated with treatment success.

OBJECTIVE To analyze the clinical characteristics and influential factors of drug-induced liver injury （DILI） in children caused by intravenous azithromycin. METHODS Clinical data of 157 DILI pediatric cases caused by intravenous azithromycin， reported by the Hengshui Adverse Drug Reaction Monitoring Center from January 2015 to January 2025， were collected as the observation group. Clinical data of pediatric patients who received intravenous azithromycin but did not develop DILI during the same period at Hengshui People’s Hospital were collected in a 1∶1 ratio to serve as the control group. The clinical classification， severity and prognosis of DILI in pediatric patients from the observation group were analyzed. Univariate and multivariate Logistic regression analyses were used to screen the independent risk factors for DILI in children caused by intravenous azithromycin. RESULTS Among 157 DILI cases， 92 cases （58.60%） had hepatocellular injury-type， 51 cases （32.48%） had cholestatic-type， and 14 cases （8.92%） had mixed-type. DILI severity was grade 1 in 117 cases （74.52%）， grade 2 in 33 cases （21.02%）， and grade 3 in 7 cases （4.46%）. Liver function had all recovered after stopping medication and symptomatic treatment. Combined with acetaminophen [OR＝3.769， 95%CI （1.615， 8.235）， P＝0.021]， daily dose of azithromycin＞10 mg/kg [OR＝ 2.237， 95%CI （1.075， 4.655）， P＝0.034] were independent risk factors for DILI in children caused by intravenous azithromycin. CONCLUSIONS Hepatocellular injury-type and cholestatic-type are relatively common in children with DILI caused by intravenous azithromycin， with mild severity being predominant and showing a favorable prognosis. Combination with acetaminophen and daily dose＞10 mg/kg are independent risk factors for azithromycin-induced DILI in children.

Objective: To understand the level of health literacy and influencing factors of Chinese general high school students, so as to provide scientific evidence for health promotion of high school students. Methods: A multistage stratified cluster sampling method was used to conduct an on site survey on the health literacy status of 8 265 high school students in 31 provinces of China by using the National Health Literacy Monitoring Questionnaire from October 2018 to June 2019. SPSS 25.0 software was used to conduct one way test and multifactor Logistic regression analysis of different demographic characteristics. Results: The health literacy level of Chinese general high school students was 7.1%; the three dimensions of literacy were ranked in descending order as follows: basic skills (21.3%), healthy lifestyles and behaviors (20.5%), and basic knowledge and concepts of health (7.8%); and the literacy levels of the six categories of health issues, in descending order, were basic medical care (88.3%), health information (75.9%), safety and first aid (51.0%), infectious disease prevention (44.2%), scientific health concept (39.0%) and chronic disease prevention (5.5%). Multifactorial Logistic regression analysis showed that ethnicity, region, family residence, school type, grade level, and father s education were the factors influencing the health literacy level of Chinese high school students( OR=2.08, 0.60/0.24, 0.44, 0.71, 1.41 /0.51, 1.37, P <0.05). Conclusions The overall health literacy level of Chinese high school students is low，ethnicity, region, family residence, school type, grade level and father s education are factors influencing the health literacy level of Chinese high school students. It is recommended that all departments at all levels focus on categorized governance to improve the health literacy level of high school students, taking into account the realities and characteristics of high school students health literacy level.

Objective:To investigate the current situation of sitting time and health literacy among high school students in China,in order to provide a basis for improving their physical and mental health levels.Methods:A stratified random cluster sampling method was used to investigate the length of sitting time and health literacy of first and second grade high school students from 31 provinces,cities,and au-tonomous regions in China(data did not include that of Hong Kong and Macao Special Administrative Re-gion,and Taiwan Province of China).The Kruskal-Wallis H method,independent sample Mann-Whit-ney U test,and regression model were used to analyze the influencing factors of sitting time and total health literacy score.Results:(1)The total score of health literacy was statistically significant(P＜0.01)in different regions,urban and rural distribution,annual family income,parents'educational background,age,and gender.(2)The length of sitting was statistically significant(P＜0.01)among multiple groups in different regions,family annual income,parental education,and gender.However,there was no statistically significant difference between groups of different ages and urban-rural distribution(P＞0.05).(3)The analysis of multiple linear regression model showed that the total score of health literacy was positively correlated with the family's annual income and the mother's education,and nega-tively correlated with the father's education and the length of sitting.Standardized regression coefficientβcomparison:Father's education(-0.32)＞family annual income(0.15)＞mother's education(0.09)＞average daily sitting time(-0.02),with father's education having the greatest impact,fol-lowed by family annual income.The length of sitting was positively related to the family's annual income and the mother's educational background,and negatively related to the total score of health literacy.Standardized regression coefficientβ comparison:Annual family income(0.14)＞education background of mother(0.13)＞total score of health literacy(-0.02),with the impact of annual family income the largest,followed by education background of mother.Conclusion:China's first and second grade high school students generally spend a long time sitting every day,and the level of health literacy is generally low.The level of health literacy and sitting time are negatively correlated with each other,and are most in-fluenced by the educational background of high school students'parents and their family economic levels.

Endometriosis (EM) refers to the implantation or growth of endometrial glands and stroma outside the uterus. The pathological mechanism of EM includes immunoinflammatory changes,oxidative stress,epithelial-stromal transition and neovascularization. EM tends to occur in women of reproductive age and seriously affects the reproductive health and quality of life of patients. At present,it is mainly treated through surgery and long-term drug management. Melatonin is an endogenous indoleamine hormone,which has various physiological functions such as antioxidant,anti-inflammatory,immune regulation and apoptosis promotion through different signaling pathways. It has attracted much attention in the treatment of cancer,cardiovascular diseases and nervous system diseases. Recent studies have found that melatonin can also inhibit the development of EM by inhibiting estrogen synthesis and antagonizing angiogenesis,and can effectively relieve pelvic pain. This article reviews the research progress on melatonin in EM in order to provide new ideas for drug therapy of EM.

Objective To investigate the correlation between random urinary albumin-to-creatinine ratio(ACR)and 24 hour urine total protein quantification(24h UTP)in patients with immunoglobulin A nephropathy(IgAN),and analyze the consistency of these methods in clinical diagnosis.Methods A total of 230 patients with primary IgAN admitted to Peking University Shenzhen Hospital from January 2019 to December 2020 were selected as the research subjects.Correlation analysis and intraclass correlation coefficient(ICC)were used to assess the correlation between ACR and 24h UTP and their consistency in clinical diagnosis.Subgroup analysis was performed using different chronic kidney disease(CKD)stages and urine protein levels.Receiver operating characteristic(ROC)curves were plotted with 24h UTP=0.5 g/24h,1.0 g/24h and 3.5 g/24h as boundary points to determine the optimal cut-off values for ACR.Results There was a positive correlation between ACR[0.79(0.41～1.45)g/g]and 24h UTP[1.02(0.58～1.80)g/24h]in patients with IgAN(r=0.85,P<0.01),and the consistency in clinical diagnosis between the two methods was moderate(ICC=0.63,P<0.01).Subgroup analysis revealed that the correlation and consistency between ACR and 24h UTP was not affected by CKD stages,with correlation coefficients(r)of different CKD staging ranging from 0.76 and 0.86(all P<0.01)and ICC values ranging from 0.53 and 0.72 across different CKD stages.However,it was affected by urine protein level.When 24h UTP was≤0.5 g/24h,there was no significant correlation between ACR and 24h UTP(r=0.08,P>0.05).In subgroups with 24h UTP≤0.5 g/24h,0.5 g/24h<24h UTP≤1 g/24h and 24h UTP>3.5 g/24h,the consistency between the two methods was negligible(all ICC<0.20).ROC curve results showed that when 24h UTP=0.5 g/24h,1.0 g/24h and 3.5 g/24h,the optimal cut-offvalues of ACR were 0.30 g/g,0.57 g/g and 1.28 g/g,respectively.Conclusion In IgAN patients,ACR cannot simply replace 24h UTP for urine protein level evaluation.Especially when 24h UTP≤1 g/24h and 24h UTP>3.5 g/24h,ACR may not accurately reflect the true urine protein level.

Objective:To assess the quality of low-keV monoenergetic images using deep learning image reconstruction (DLIR) algorithm combined with dual energy CT (DECT) in gastric cancer and to compare them with images from the conventional adaptive statistical iterative reconstruction (ASiR-V) algorithm.Methods:In this cross-sectional study, DECT images of 31 gastric cancer patients in the First Affiliated Hospital of Zhengzhou University were prospectively collected from September 2022 to March 2023. The 55 keV monoenergy images were reconstructed using the DLIR algorithm at low-, medium-, and high-intensity levels (DLIR-L, DLIR-M, and DLIR-H) based on arterial phase and venous phase images, respectively. The 70 keV 40% mixing coefficient (ASiR-V40%) images were reconstructed using the ASiR-V algorithm. In the objective evaluation of images, the signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) for both lesions and muscle were calculated across four sets of reconstructed images. In the subjective evaluation of images, scores were assigned to the overall image quality, lesion visibility, and diagnostic confidence for each set of reconstructed images. Comparisons of SNR and CNR between the 4 groups were made by One-way repeated-measures ANOVA or Friedman′s test. Comparisons of scores were made by Friedman′s test. The P value of pairwise comparison was adjusted using Bonferroni correction methods. Results:In the objective evaluations, CNR lesion, SNR lesion and SNR muscle were highest on the 55 keV DLIR-H images in the arterial and venous phases, and showed a gradually increasing trend on the 70 keV ASiR-V40%, 55 keV DLIR-L, DLIR-M, DLIR-H images ( P<0.05). In subjective evaluations, compared to the 70 keV ASiR-V40% images, overall image quality scores were numerically higher for the 55 keV DLIR-H ( P>0.05), similar or slightly worse for the 55 keV DLIR-M, and significantly lower for the 55 keV DLIR-L ( P<0.05). The lesion visibility and diagnostic confidence on the 55 keV DLIR reconstruction images were higher in both arterial and venous phases than 70 keV ASiR-V40% images ( P<0.05). Conclusions:Compared to the conventional 70 keV ASiR-V40% images, the 55 keV DLIR-H images had higher lesion contrast and diagnostic confidence with lower image noise. The 55 keV DLIR-M images had comparable overall image quality to 70 keV ASiR-V40% images, but the former had higher lesion contrast and diagnostic confidence. The 55 keV DLIR-L was unable to improve image quality to the level of 70 keV ASiR-V40%.
