OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

Objective To describe the changing trend and related factors of prevalence rates of healthcare-associa-ted infection(HAI)in a tertiary hospital in the past 10 years,and analyze the influencing factors for HAI.Methods A cross-sectional survey on HAI was conducted for 10 consecutive years from 2013 to 2022(one day was selected as the survey day each year),data were collected.The distribution and related factors of prevalence rates of HAI were analyzed by trend-x2 test and Pearson correlation coefficient.Multivariate logistic regression and multilayer percep-tron(MLP)models were constructed to analyze the independent effect and significance of factors.Results From 2013 to 2022,the prevalence rates of HAI ranged from 4.66％to 8.07％in this hospital,showing a linear upward trend.The proportions of ICU patients and utilization rate of central venous catheters within 2 days before the sur-vey showed linear upward trends,while the proportion of patients with urinary catheters within 2 days before the survey and proportion of patients undergoing surgery within 30 days before the survey decreased.The MLP model revealed that the top 3 important factors for HAI were length of hospital stay＞10 days,admission in ICU,and in-dwelling central venous catheters within 2 days before the survey.Multivariate logistic regression model indicated that length of hospital stay＞10 days,indwelling central venous catheters or urinary catheters within 2 days before the survey,surgery within 30 days before the survey,and admission in ICU were independent influencing factors for HAI.Conclusion The incidence of HAI in this hospital presents a linear increase in recent 10 years,the causes should be further analyzed and the direction of intervention should be determined through targeted surveillance.Adopting trend test statistical analysis method,logistic regression,MLP multi-factor model can further explore the data value of HAI prevalence survey.

ObjectiveTo investigate the mRNA expression levels of various aquaporins （AQPs） in luteinized granulosa cells from follicles of different diameters. MethodsFrom March 25， 2022 to September 23， 2022 in our reproductive medicine center， 48 women undergoing in-vitro fertilization （IVF） were enrolled and divided into the antagonist group and the agonist group according to the ovarian stimulation protocol. Follicular fluid samples were collected on the day of oocyte pick-up and granulosa cells were extracted from follicles of different diameters： small （<13 mm）， medium （13~18 mm） and large （≥18 mm）. After RNA quantification， 22 cases （66 samples） were included for analysis and mRNA expression levels of AQPs were compared among the three follicle groups. ResultsThe mRNA expression of aquaporin 2 （AQP2） in luteinized granulosa cells increased with the increase of follicle diameter （linear trend P = 0.004） and the difference was statistically significant between two groups of large and small follicles （P = 0.017）. Statistical difference was found in the antagonist group （P = 0.049 6）， but not in the agonist group （P = 0.108）. ConclusionThe mRNA level of AQP2 in luteinized granulosa cells increases with the increase of follicle diameter and its expression is related to the ovarian stimulation protocol， suggesting that AQP2 may play a role in follicle growth and follicular fluid formation， and its mRNA expression level may be regulated by follicle stimulating hormone （FSH） and luteinizing hormone （LH）.

OBJECTIVES: To explore a new method for electroencephalography (EEG) background analysis in neonates with hypoxic-ischemic encephalopathy (HIE) and its relationship with clinical grading and head magnetic resonance imaging (MRI) grading. METHODS: A retrospective analysis was performed for the video electroencephalography (vEEG) and amplitude-integrated electroencephalography (aEEG) monitoring data within 24 hours after birth of neonates diagnosed with HIE from January 2016 to August 2022. All items of EEG background analysis were enrolled into an assessment system and were scored according to severity to obtain the total EEG score. The correlations of total EEG score with total MRI score and total Sarnat score (TSS, used to evaluate clinical gradings) were analyzed by Spearman correlation analysis. The total EEG score was compared among the neonates with different clinical gradings and among the neonates with different head MRI gradings. The receiver operating characteristic (ROC) curve and the area under thecurve (AUC) were used to evaluate the value of total EEG score in diagnosing moderate/severe head MRI abnormalities and clinical moderate/severe HIE, which was then compared with the aEEG grading method. RESULTS: A total of 50 neonates with HIE were included. The total EEG score was positively correlated with the total head MRI score and TSS (r_s=0.840 and 0.611 respectively, P<0.001). There were significant differences in the total EEG score between different clinical grading groups and different head MRI grading groups (P<0.05). The total EEG score and the aEEG grading method had an AUC of 0.936 and 0.617 respectively in judging moderate/severe head MRI abnormalities (P<0.01) and an AUC of 0.887 and 0.796 respectively in judging clinical moderate/severe HIE (P>0.05). The total EEG scores of ≤6 points, 7-13 points, and ≥14 points were defined as mild, moderate, and severe EEG abnormalities respectively, which had the best consistency with clinical grading and head MRI grading (P<0.05). CONCLUSIONS The new EEG background scoring method can quantitatively reflect the severity of brain injury and can be used for the judgment of brain function in neonates with HIE.

OBJECTIVE: To analyze the clinical efficacy of haploidentical hematopoietic stem cell transplantation (haplo-HSCT) by using parental donors on thalassemia patients. METHODS: The 13 thalassemia patients treated by haplo-HSCT using parental donors in our hospital from July 1, 2016, to July 1, 2020 were retrospectively reviewed. Hematopoiesis reconstitution, the incidence of GVHD, infections and the long-term survival of the patients were analyzed. RESULTS: Twelve of the 13 patients were successfully implanted, the success rate of implantation was 92.3%. The median time of neutrophil and platelet engraftment was 12.5 days (range, 9-22 days) and 21 days (range,12-34 days), respectively. One patient achieved primary graft failure. Three (25%) patients developed to acute GVHD (aGVHD) and achieved complete remission after treatment. Chronic GVHD developed in three (25%) patients, one of them was extensive and under treatment, while one patient developed to severe bacterial infection (7.7%). CMV viremia was diagnosed in two patients (15.4%). There were no patients developed to CMV disease. Three (23.1%) patients achieved EB viremia after transplantation, one of them developed to EBV-related lymphocytic proliferative disease, while there were no patients showed invasive fungal infection. At the last follow-up, all patients survived, twelve of them were free from transfusion dependency. There were no transplant-related deaths. Projected overall and thalassemia-free survival at three years was 100% and 92.3%, respectively. CONCLUSION The transplant protocol of haplo-HSCT by using parental donors in patients with thalassemia has reliable source of donors, high incidence of successful implantation and low incidence of GVHD, which can be used as an effective way to increase the source of donors in children with thalassemia.

OBJECTIVE: To retrospectively analyze the efficacy and safety of ruxolitinib therapy for children with thalassemia after unrelated or haploidentical stem cell transplantation. METHODS: From March 2020 to March 2021, 22 patients received successfully allogeneic hematopoietic stem cell transplantation in the Zhongshan Hospital of Xiamen University, from +30 to 100 days,those patients received ruxolitinib therapy (2.5 mg, twice daily) and all adverse reactions were observed, include aGVHD, cGVHD, CMV and EBV infection. RESULTS: 22 patients underwent allogeneic stem cell transplantation, 5 patients were diagnosed as aGVHD, 3 patients had grade I－II skin GVHD and 2 patients had grade II intestinal GVHD, those patients were cured. All patients were followed up for more than 21 weeks, 4 cases developed cGVHD, including 3 cases of localized liver GVHD and 1 case of pulmonary GVHD, those were relieved after active treatment. 8 patients had elevated EBV copies (>3×10³/ml), and 3 patients had increased CMV copies, the patients recovered after immunosuppressant and antiviral treatment. There was no CMV infection and EBV related post-transplantant lymphoproliferative disorders(PTLD), and no transplant related deaths. CONCLUSION Ruxolitinib can effectively reduce the incidence and severity of GVHD without affecting the hematopoietic recovery, and improve the survival status of thalassemia children after transplantation.

Objective: To investigate the effect of maternal exposure to lipopolysaccharide during pregnancy on allergic asthma in offspring in mice. Methods: Animal experimental research was carried out from June 2019 to June 2021.Pregnant C57BL/6J mice were randomly divided into 2 groups by intraperitoneal injection with 7 μg/kg lipopolysaccharide (LPS) or phosphate buffered saline (PBS) at day 15.5 of gestation. After birth, 6 offspring were randomly chosen from each group at the age of 4 weeks, and stimulated with house dust mites (HDM) or PBS, further divided into 4 groups, such as LPS+PBS group, LPS+HDM group, PBS+PBS group, PBS+HDM group, with 3 mice in each group. The cough and wheezing were observed, the histological changes in lung tissue were examined after HE staining, and the expression of inflammatory factors including interleukin (IL)-4, IL-6, IL-17A, IL-23, interferon (IFN)-α and IFN-β in the lung tissue were detected by high-throughput liquid protein chip detection. T test or rank sum test was used for the comparison among these groups. Results: The asthma-like airway inflammation was more obvious in PBS+HDM group after stimulated by HDM than that in PBS+PBS group, nevertheless, this manifestation in LPS+HDM group was milder than that in PBS+HDM group. HE staining showed that inflammatory cell aggregation in the lung tissue in PBS+HDM group was significantly higher than that in PBS+PBS group (4.0 (3.5, 4.0) vs. 0 (0, 0.5), Z=2.02, P=0.043), while it was much lower in LPS+HDM group compared to PBS+HDM group (1.0 (0.5, 1.5) vs. 4.0 (3.5, 4.0), Z=1.99, P=0.046). High-throughput liquid protein chip detection of lung tissue showed that IL-6, IL-23 and IFN-β levels were significantly higher in PBS+HDM group when compared to those in PBS+PBS group ((114±3) vs. (94±4) ng/L, (210±4) vs. (173±7) ng/L, (113±2) vs. (94±4) ng/L, t=4.37, 4.84, 3.96, all P<0.05), while the levels of IL-6, IL-23, IFN-α, IFN-β in LPS+HDM group were significantly lower than those in PBS+HDM group ((87±5) vs. (114±3) ng/L, (171±7) vs. (210±4) ng/L, (16.1±0.6) vs. (20.9±0.3) ng/L, (95±1) vs. (113±2) ng/L, t=5.07, 5.07, 7.28, 7.47, all P<0.05). Conclusions: Prenatal low dose LPS exposure can reduce offspring's airway inflammatory reactions and prevent the development of allergic disease. Maternal infection during pregnancy may affect the occurrence and development of allergic asthma in offspring.

Carboxyl CoA ligases(CCLs) is an important branch of adenylate synthetase gene family, which mainly has two-step catalytic reactions. Firstly, in the presence of adenosine triphosphate, it can catalyze the pyrophosphorylation of carboxylateswith diffe-rent structures to form corresponding acyl adenosine monophosphate intermediates. Secondly, adenosine monophosphate was replaced by free electrons in the mercaptan group of enzyme A or other acyl receptors by nucleophilic attack to form thioesters. In this study, on the basis of the transcriptome database of Arnebia euchroma, two genes were selected, named AeCCL5(XP_019237476.1) and AeCCL7(XP_019237476.1). Bioinformatics analysis showed that their relative molecular weights were 60.569 kDa and 60.928 kDa, theoretical PI were 8.59 and 8.92, respectively. They both have transmembrane domains but without signal peptide. By multiple sequence alignment and phylogenetic tree analysis, we found that the similarity between AeCCLs and other plant homologous proteins was not high, and the substrate binding sites of AeCCLs were not highly conserved. The reasons might be that the sequence and structure need to adapt to the changes of new substrates in the process of evolution. In this study, the full-length of AeCCL5 and AecCCL7 were cloned into the expression vector pCDFDuet-1. The proteins of AeCCL5 and AeCCL7 with His-tag were expressed in Escherichia coli. The proteins of AeCCL5 and AeCCL7 were purified by nickel column. In vitro enzymatic reactions proved that both AeCCL5 and AeCCL7 can participate in the upstream phenylpropane pathway of shikonin biosynthesisby catalyzing 4-coumaric acid to produce 4-coumarin-CoA, and then to synthesis p-hydroxybenzoic acid, which is an important precursor of shikonin biosynthesis in A. euchroma.
