Andrographolide sulfonate (AS) is a sulfonated derivative of andrographolide extracted from Andrographis paniculata (Burm.f.) Nees, and has been approved for several decades in China. The present study aimed to investigate the novel therapeutic application and possible mechanisms of AS in the treatment of rheumatoid arthritis. Results indicated that administration of AS by injection or gavage significantly reduced the paw swelling, improved body weights, and attenuated pathological changes in joints of rats with adjuvant-induced arthritis. Additionally, the levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and IL-1β in the serum and ankle joints were reduced. Bioinformatics analysis, along with the spleen index and measurements of IL-17 and IL-10 levels, suggested a potential relationship between AS and Th17 cells under arthritic conditions. In vitro, AS was shown to block Th17 cell differentiation, as evidenced by the reduced percentages of CD4⁺ IL-17A⁺ T cells and decreased expression levels of RORγt, IL-17A, IL-17F, IL-21, and IL-22, without affecting the cell viability and apoptosis. This effect was attributed to the limited glycolysis, as indicated by metabolomics analysis, reduced glucose uptake, and pH measurements. Further investigation revealed that AS might bind to hexokinase2 (HK2) to down-regulate the protein levels of HK2 but not glyceraldehyde-3-phosphate dehydrogenase (GAPDH) or pyruvate kinase M2 (PKM2), and overexpression of HK2 reversed the inhibition of AS on Th17 cell differentiation. Furthermore, AS impaired the activation of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signals in vivo and in vitro, which was abolished by the addition of lactate. In conclusion, AS significantly improved adjuvant-induced arthritis (AIA) in rats by inhibiting glycolysis-mediated activation of PI3K/AKT to restrain Th17 cell differentiation.

OBJECTIVES: To explore the mechanism through which moxibustion promotes endometrial repair in rats with in thin endometrium (TE). METHODS: Female SD rats were randomized into control group, 95% anhydrous ethanol-induced TE model group and moxibustion (at "Guan Yuan") group. High-throughput sequencing was used to identify the target genes of TE, and the targeting relationship between miR-223-3p and NLRP3 was verified using a dual luciferase assay. Histopathological of rat uterus was observed with HE staining, and expressions of miR-223-3p and NLRP3 were detected using RT-qPCR; serum levels of IL-1β and IL-18 of the rats were detected using ELISA, and protein expressions of NLRP3, ASC, caspase-1 and GSDMD in the uterus were detected with Western blotting. The pregnancies of the rats after treatment were counted. RESULTS: Enrichment analysis of the differential genes suggested up-regulated inflammatory response in TE, and dual luciferase assay verified targeted inhibition of NLRP3 expression by miR-223-3p. The rat models of TE had significantly decreased endometrial thickness and reduced endometrial glands and blood vessels with enhanced mRNA expression of NLRP3, increased serum levels of IL-1β and IL-18, up-regulated protein expressions of NLRP3, ASC, caspase-1 and GSDMD, lowered pregnancy rates on both the affected and unaffected sides and the overall number of pregnancies. Treatment of the rat models with mo-xibustion obviously increased the endometrial thickness and the density of glands and blood vessels, up-regulated miR-223-3p expression, lowered serum IL-1β and IL-18 levels and the protein expressions of NLRP3, ASC, caspase-1 and GSDMD, and significantly increased the number of pregnancies. CONCLUSIONS Moxibustion at "Guan Yuan" acupoint up-regulates the expression of miR-223-3p, which results in targeted inhibition of NLRP3 to suppress pyroptosis and promote endometrial repair in rat models of TE.

Objective:To investigate the clinical significance of elevated cytokeratin 19 fragment (CYFRA21-1) in patients with dermatomyositis associated with positive anti-melanoma differentiation-associated gene 5 (MDA5) antibody.Methods:142 consecutive cases with newly onset anti-MDA5(+) (MADEDM)-DM admitted to the first affiliated hospital of Zhengzhou University from June 2018 to October 2021 were enrolled. They were divided into two groups, the low serum CYFRA21-1 group (CYFRA21-1≤4 ng/ml) and the high serum CYFRA21-1 group (CYFRA21-1>4 ng/ml). The clinical manifestations, laboratory tests results, imaging examinations treatment and outcome were collected for statistical analysis. Enumeration data were expressed as the number of cases and percentage (%). Normally distributed parameters were tested by t-test. Parameters with skewed distribution were tested by Mann-Whitney Wilcoxon analysis. Categorical variables were compared by the Chi-square test or Fisher′s exact test. Risk factor analysis was performed using Logistic regression. Cumulative survivals were described by Kaplan-Meier curves. Results:The age of onset in the high CYFRA21-1 group [(56±9)years vs. (50±10) years, t=-3.50, P=0.001] was higher than that in the low CYFRA21-1 group. Fever [63.3% (38/60) vs. 40.2% (33/82), χ2=7.39, P=0.007] was more common in the high CYFRA21-1 group, and arthritis [41.7% (25/60) vs. 69.5%(57/82), χ2=11.01, P=0.001] was less common. Myalgia, myasthenia, rashes, Raynaud′s phenomenon and skin ulcers had no significant difference between the two groups. The WBC count [5.2(4.1, 6.9)×10 9/L vs. 4.3(3.2, 6.2)×10 9/L, Z=-2.57, P=0.010], neutrophil count [4.0(2.9, 5.5)×10 9/L vs. 2.9(2.1, 4.5)×10 9/L, Z=-3.25, P=0.001] and neutrophil/lymphocyte ratio [5.75(3.50, 9.20) vs. 3.55(2.64, 5.41), Z=-3.77, P<0.001] in high CYFRA21-1 group were significantly higher than those in low CYFRA21-1 group. At the same time, LDH [384(302, 519)U/L vs. 318(260, 405)U/L, Z=-2.98, P=0.003], ferritin [1 204(677, 2 039)ng/ml vs. 570(229, 846)ng/ml, Z=-4.78, P<0.001], KL-6 [995(658, 1 491)U/ml vs. 750(563, 1 197)U/ml, Z=-2.49, P=0.013], ESR [36(22, 61)mm/1 h vs. 28(15, 46)mm/1 h, Z=-2.18, P=0.029] and CRP [9.2(4.7, 31.5)mg/L vs. 3.1(1.1, 11.6)mg/L, Z=-3.53, P<0.001] were significantly increased in the high level of CYFRA21-1 group, while serum albumin[(32±5)g/L vs. (35±5)g/L, t=3.92, P<0.001] was significantly decreased. There was no significant difference in the titers of serum anti-MDA5 antibodies between the two groups. The positive rate of anti-RO52 antibody [44(74.6%) vs. 44(53.7%), χ2=6.40, P=0.011] in high CYFRA21-1 group was higher than that in low CYFRA21-1 group. The ground glass opacity (GGO) score [1.75(1.33, 2.42) vs. 1.09(0.67, 1.67), Z=-4.60, P<0.001] based on high resolution CT (HRCT) was also significantly increased in the CYFRA21-1 high level group. Compared with the low CYFRA21-1 group, the high CYFRA21-1 group had a higher probability of RP-ILD [48.3%(29/60) vs. 23.2%(19/82), χ2=9.80, P=0.002] and a higher 6-month mortality rate[48.3%(29/60) vs.13.4%(11/82), χ2=19.70, P<0.001]. Logistic regression analysis showed that age ≥53 years old [ OR(95% CI)=5.197(1.781, 15.165), P=0.003], duration < 2 months [ OR(95% CI)=3.314 (1.058, 10.378), P=0.040], NE/LYMP >5 [ OR(95% CI)=3.443(1.120, 10.586), P=0.031], CRP>5 mg/L[ OR(95% CI)=6.271(1.749, 22.480), P=0.005], CA125>14 U/ml[ OR(95% CI)=7.500 (2.409, 23.345), P=0.001] and CYFRA21-1>4 ng/ml[ OR(95% CI)=3.665(1.258, 10.676), P=0.017] were independent risk factors for death within 6 months in MDA5-DM patients. Kaplan-Meier survival curve showed that the survival rate of the high CYFRA21-1 group was significantly lower than that of the low CYFRA21-1 group( P<0.001). Conclusion:Elevated CYFRA21-1 is an independent risk factor for early mortality in MDA5-DM patients and can serve as a novel serological marker for risk stratification in these patients.

Objective To compare the reparative effects of moxibustion at"Guanyuan"and"Shenshu"points in rats with a thin endometrium.Methods Thirty-two female Sprague-Dawley rats were divided randomly into control(CON),model(MOD),Guanyuan(GY),and Shenshu(SS)groups.A thin endometrium model was established using 95％anhydrous alcohol.The Guanyuan and Shenshu groups underwent moxibustion at the Guanyuan and Shenshu points,respectively,and the other two groups of rats were fixed in the same way.Temperature changes at the acupoint area were measured at different time points.The pathological morphology of the uterus was observed by hematoxylin and eosin(HE)staining,and serum levels of inflammatory factors and hormone levels were detected by enzyme-linked immunosorbent assay(ELISA).Expression levels of proliferation and endometrial receptivity factors were detected by immunohistochemistry(IHC),and angiogenesis factors were detected by Western blot.Results The temperatures immediately after moxibustion and after 5 min were higher at the Shenshu compared with the Guanyuan acupoint(P＜0.01).Endometrial thickness and numbers of glands and blood vessels were decreased in the MOD group compared with the CON group(P＜0.01),serum interleukin 1 β(IL-1 β)was increased(P＜0.01)and PROG was decreased(P＜0.01),and Ki67,proliferating cell nuclear antigen(PCNA),leukemia inhibitory factor(LIF),integrin β3(ITG-β3),angiopoietin-1(ANG-1),and CD34 protein in uterine tissue were all decreased(P＜0.01).Endometrial thickness and numbers of glands and blood vessels were increased in the GY and SS groups compared with the MOD group(P＜0.01),while serum IL-1 β was decreased(P＜0.05),E2 and PROG were increased(P＜0.05),and serum interleukin 10(IL-10)was increased in the SS group(P＜0.05).Ki67,PCNA,LIF,and ITG-β3 were all increased in both treatment groups compared with the MOD group(P＜0.01).PCNA was higher in the GY group compared with the SS group(P＜0.05),while LIF and ITG-β3 were higher in the SS group compared with the GY group(P＜0.01,P＜0.05,respectively).CD34 and VEGFA levels were increased in the two treatment groups compared with the model group(P＜0.01).ANG-1 was higher in the GY group than that in the SS group(P＜0.01),while CD34 was higher in the SS group than that in the GY group(P＜0.05).Conclusions Moxibustion at the Guanyuan and Shenshu points could help to repair the pathological thin endometrium in rats.The GY group may be superior to the SS group for reducing the levels of serum IL-1 β,increasing E2,and promoting the expression of proliferation factors,while the SS group may be superior to the GY group for increasing the levels of PROG and promoting the expression of endometrium receptor-related factors.Both acupoints can promote the expression of angiogenesis factors,potentially acting via different pathways.

Objective:To investigate the clinical efficacy and safety of ferric derisomaltose injection versus iron sucrose injection in the treatment of iron deficiency anemia (IDA) .Methods:A total of 120 patients with iron deficiency anemia admitted from June 2021 to March 2023 were given intravenous iron supplementation with ferric derisomaltose to assess the efficacy and safety of hemoglobin (HGB) elevation before and after treatment. Simultaneously, the clinical effects of iron supplementation with iron sucrose were compared to those of inpatient patients during the same period.Results:Baseline values were comparable in both groups. Within 12 weeks of treatment, the elevated HGB level in the ferric derisomaltose group was higher than that of the iron sucrose group, with a statistical difference at all time points, and the proportion of HGB increased over 20 g/L in the patients treated for 4 weeks was higher (98.7%, 75.9% ). During the treatment with ferric derisomaltose and iron sucrose, the proportion of mild adverse reactions in the ferric derisomaltose group was slightly lower than that of the iron sucrose group, and neither group experienced any serious adverse reactions. The patients responded well to the infusion treatment, with no reports of pain or pigmentation at the injection site.Conclusion:The treatment of IDA patients with ferric derisomaltose has a satisfactory curative effect, with the advantages of rapidity, accuracy, and safety. Therefore, it is worthy of widespread clinical use.

Objective:This study aimed at investigating the efficacy and safety of eltrombopag in the treatment of adult primary immune thrombocytopenia (ITP) and evaluated the factors influencing its efficacy and side effects.Methods:A total of 198 patients with adult ITP who were admitted to Tianjin Medical University General Hospital between January 2018 and March 2022 were retrospectively analyzed. The efficacy of each starting dose of eltrombopag was evaluated, and adverse events were analyzed. The factors influencing efficacy were investigated, including sex, age, adult ITP type, platelet antibodies, and combined drug treatments.Results:Of the 198 patients, 70 males and 128 females with a median age of 45 years (18-88 years) were included; 130 (65.7%) had newly diagnosed adult ITP, 25 (12.6%) had persistent adult ITP, and 43 (21.7%) had chronic adult ITP. The bleeding event scores at baseline were assessed; 84.3% had scores of<4 and 15.7% had scores of ≥4. The eltrombopag response rate (initial response) at 6 weeks was 78.8% (complete response [CR]: 49.0%; CR1: 14.6%; CR2: 15.2%). The median response time to eltrombopag was 7 (7, 14) days. The initial response rates to 25, 50, and 75 mg eltrombopag were 74.1%, 85.9%, and 60.0%, respectively ( P=0.031). The initial response rate to the 50 mg dose was significantly higher than that of the 25-mg and 75-mg doses. Two patients received 100 mg as the starting dose, and their initial response was 0. Regarding dose adjustment, 70.7% of the patients remained on the starting dose, 8.6% underwent dose adjustment to 50 mg, and 6.1% underwent dose adjustment to 75 mg. Another two patients underwent dose adjustment to 100 mg. After dose adjustment, the persistent response rates were 83.6%, 85.3%, and 85.7% for the 25-, 50-, and 75-mg doses, respectively, with no significant difference. After dose adjustment, the sustained efficacy rate for the 100-mg dose (4 patients) was 100.0%. After 6 weeks of treatment with eltrombopag, the overall bleeding score of patients with ITP decreased. The number of patients with a score of ≥4 decreased to 0, the number of patients with a score of<4 decreased, and there was no significant change in the number of patients with a score of 1-2. The most common adverse event associated with eltrombopag was impaired liver function (7.7%). No thrombosis events or other adverse events were observed. ITP type and number of megakaryocytes significantly affected the initial response to eltrombopag. The initial response rates to eltrombopag for newly diagnosed adult ITP, persistent adult ITP, and chronic adult ITP were 85.3%, 56.0%, and 76.2%, respectively ( P=0.003). For megakaryocytes, the initial response rates were 61.8%, 87.1%, and 84.3% ( P=0.009) for the decreased, normal, and increased megakaryocyte groups, respectively. Conclusion:Eltrombopag, as a second-line or higher treatment for adult ITP, has a rapid onset of action and good safety. The initial response rate is significantly higher with a dose of 50 mg than with a dose of 25 mg. Patients with newly diagnosed ITP and those with normal or increased megakaryocyte numbers have a higher initial response rate to eltrombopag.

Objective:To analyze the distribution and drug resistance of pathogens of bacterial bloodstream infection in patients with hematological diseases in the Department of Hematology of Tianjin Medical University General Hospital, and to provide etiological data for clinical empirical anti-infection treatment.Methods:A retrospective analysis was conducted on the general clinical information, pathogenic bacteria and drug susceptibility test results of patients with hematological diseases diagnosed with bacterial bloodstream infection by menstrual blood culture in our center from January 2016 to December 2022.Results:Patients included 498 inpatients, with a total of 639 bacterial strains. Among the patients, 86.9% patients had malignancies, and 76.7% had agranulocytosis. Symptoms of concurrent infections, including those of the respiratory tract, oral mucosa, skin and soft tissues, and abdominal sources were observed in 68.3% patients. Gram-negative bacteria (G -) accounted for 79.0% of the isolated bacteria, and gram-positive bacteria (G +) accounted for 21.0%. The top five isolated pathogens were Klebsiella pneumoniae (22.5%), Escherichia coli (20.8%), Pseudomonas aeruginosa (15.0%), Enterococcus faecium (5.5%), and Stenotrophomonas maltophilum (5.0%). Escherichia coli exhibited a decreasing trend of resistance to quinolones, cephalosporins, and carbapenems. Klebsiella pneumoniae exhibited increasing rates of resistance to quinolones and cephalosporins between 2016 and 2018, but the rated decreased after 2019. The resistance rate to carbapenems exhibited by Pseudomonas aeruginosa was approximately 20%. Carbapenem-resistant strains of Pseudomonas aeruginosa strains were first detected in 2017, with a peak resistance rate of 35.7%, detected in 2019. A 60.0% resistance rate to methicillin was observed in methicillin-resistant coagulase-negative staphylococci (MRCNS), and one case of linezolid-resistant MRCNS was detected. Conclusions:Pathogenic bacteria of bacterial bloodstream infections were widely distributed in our center, and precautions are warranted against carbapenem resistant P. aeruginosa and Klebsiella pneumoniae.

Objective:To analyze and compare the association between different obesity-related indices and vitamin D deficiency in middle-aged and elderly population dwelled in Lanzhou city.Methods:From May, 2011 to September, 2012, middle-aged and elderly individuals with complete baseline data were included via randomly cluster sampling from 3 communities in Lanzhou. The subjects were divided into 4 subgroups by vitamin D levels and various obesity-related indices were compared across subgroups with the same gender. The relationship between the obesity-related indices and the severity of vitamin D deficiency was analyzed using Spearman correlation analysis, and the effects of different obesity-related indices on the severity of vitamin D deficiency was analyzed using multivariate logistic regression analysis.Results:A total of 9 437 residents were included. The overall prevalence of vitamin D deficiency was 97.7%. Compared with the group with lower vitamin D level, participants in the group with higher vitamin D level showed evidently lower body mass index (BMI), waist circumference (WC), lipid accumulation product (LAP), visceral adiposity index (VAI) and triglyceride/ high density lipoprotein cholesterol (TG/HDL-C) ratio in the total population and females, while only WC, LAP, VAI and TG/HDL-C in the males (all P<0.05). Spearman correlation analysis showed that BMI, WC, LAP, VAI and TG/HDL-C were positively correlated with the severity of vitamin D deficiency in the total population and the females, while only LAP, VAI and TG/HDL-C in the males (all P<0.05) . Multivariate logistic regression analysis showed that higher levels of these obesity related indices were correlated with more severe vitamin D deficiency in the total population and the females, while only higher LAP, VAI and TG/HDL-C in the males (all P<0.05). The effects of higher LAP was the most prominant in the total population ,the females and the males. Conclusion:Various obesity phenotypes are closely related to vitamin D deficiency in middle-aged and elderly women, while only visceral obesity and abnormal lipid metabolism are related to vitamin D deficiency in middle-aged and elderly men, with LAP being the most important influencing factor.
