Objective:To further investigate the safety and efficacy of Belimumab in the treatment of patients with systemic lupus erythematosus (SLE).Methods:All SLE patients treated with Belimumab from May 1, 2020 to February 1, 2022 in Peking Union Medical College Hospital were retrospectively collected and analyzed. The clinical manifestations, the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2000) score, and laboratory test such as levels of anti-dsDNA antibody, the medication before and after Belimumab treatment, adverse events were collected. Normally distributed data were tested using the t-test, otherwise the Wilcoxon paired signed rank test was used. Results:A total of 81 patients were enrolled in this study. The use of belimumab could significantly decrease the SLEDAI-2000 score [10.00(7.75, 12.00) vs. 4.00(3.75, 6.00), Z=-5.38, P<0.001], ESR of SLE patients [19.50(12.75, 32.25) mm/1 h vs. 14.00(7.75, 20.25) mm/1 h, Z=-3.71, P=0.003], anti-dsDNA titer detected by CLIFT [300.00 (117.00, 864.00) vs. 183.00(100.00, 471.00), Z=-4.15, P=0.001], meanwhile, increase the complement C3 [0.78 (0.62, 0.97)g/L vs. 0.69 (0.55, 0.84)g/L, Z=-4.68, P<0.001], and the complement C4 [0.12 (0.08, 0.19)g/L vs. 0.10 (0.05, 0.14)g/L, Z=-4.78, P<0.001]. We also observed that with the use of Belimumab, the dosage of Glucocorticoids decreased significantly, which were [10.00(7.50, 22.50) mg vs. 7.50(5.00, 10.00) mg, Z=-4.90, P<0.001]. In addition, the antibody of IgG, IgA and IgM decreased significantly. Only one patient stopped the administration of Belimumab due to the low level of immunoglobulin. Conclusion:Belimumab can alleviate disease activity of patients with SLE and help in safely tapering the daily dose of glucocorticoid with good safety.

Background/Aims: Previous studies have shown that diet and physical activity can influence constipation. However, the combined effect of diet and physical activity on constipation remains unclear. Methods: Constipation was defined based on stool consistency and frequency, while overall diet quality was assessed using Healthy Eating Index (HEI)-2015 scores. Participants were categorized into low (metabolic equivalent [MET]-min/wk < 500) and high physical activitygroups (MET-min/wk ≥ 500). The association between diet and constipation across physical activity groups was analyzed using surveylogistic regression and restricted cubic splines. Results: Higher HEI-2015 scores were associated with reduced constipation risk in the high physical activity group when constipation was defined by stool consistency (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.97-0.99). However, in the low physical activity group, increased HEI-2015 scores did not significantly affect constipation risk (OR, 1.01; 95% CI, 0.97-1.05). Similar results were found when constipation was defined based on stool frequency. In the high physical activity group, increased HEI-2015 scores were significantly associated with a reduced constipation risk (OR, 0.96; 95% CI, 0.94-0.98). Conversely, in the low physical activity group, increased HEI-2015 scores did not affect the risk of constipation (OR, 0.96; 95% CI, 0.90-1.03). Conclusions Our findings suggest that a higher HEI-2015 score is negatively associated with constipation among individuals with high physical activity levels but not among those with low physical activity levels. This association was consistent when different definitions of constipation were used. These results highlight the importance of combining healthy diet with regular physical activity to alleviate constipation.

Objective:To compare the efficacy and safety of oral terbinafine versus itraconazole in the treatment of pediatric tinea capitis.Methods:From January 2021 to December 2021, a randomized clinical trial was conducted among 53 children with tinea capitis in Beijing Children′s Hospital. These patients were randomly divided into 2 groups by using a random number table: terbinafine group treated with oral terbinafine at different doses (weight <20 kg, dose: 62.5 mg/d; weight 20 - 40 kg, dose: 125 mg/d; weight >40 kg, dose: 250 mg/d), while itraconazole group treated with oral itraconazole at doses of 3 - 5 mg·kg -1·d -1. Statistical analysis was performed using the SPSS 23.0 software, and enumeration data were compared between groups by using chi-square test or Fisher′s exact test. Results:Totally, 27 patients were treated with oral terbinafine, including 17 with tinea alba and 10 with kerion; 26 were treated with oral itraconazole, including 17 with tinea alba and 9 with kerion. After treatment, 14 (51.85%) patients were cured in the terbinafine group, including 5 with tinea alba and 9 with kerion, while 25 (96.15%) were cured in the itraconazole group, including 16 with tinea alba and 9 with kerion. The response rate was significantly higher in the itraconazole group than in the terbinafine group ( χ2 = 13.37, P < 0.001) . Conclusion:The efficacy of itraconazole was superior to that of terbinafine in the treatment of pediatric tinea alba, but their efficacy was equivalent in the treatment of pediatric kerion.

Objective:To estimate the incidence and risk factors of acute kidney injury (AKI) in preterm infants, and provide basis for better evaluation and treatment of renal function in preterm infants.Methods:All the hospitalized premature infants who were admitted to three research centers (Department of Neonatology at Beijing Children′s Hospital; Department of Neonatology at Beijing Obstetrics and Gynecology Hospital; Department of Neonatology at Shunyi Maternal and Children′s Hospital of Beijing Children′s Hospital)from January 1, 2017 to June 30, 2019 and had more than two serum creatinine values or urine output were included.The incidence of AKI in preterm infants was calculated and the difference among different gestational weeks was compared.Preterm infants were divided into AKI and non-AKI groups according to AKI diagnostic criteria, and the clinical characteristics between two groups were compared, and the risk factors of AKI in preterm infants were analyzed.Results:A total of 763 premature infants were included in the analysis.Twenty two cases were diagnosed with AKI.The incidence of AKI in premature infants was 2.9%.The incidence of AKI was 33.3% (3/9), 3.7% (5/134), and 2.3% (14/620) in the 24-27 + 6 weeks, 28-31 + 6 weeks, and 32-36 + 6 weeks gestational age, respectively, and the difference was statistically significant ( χ2=31.010, P<0.001). Preterm infants in AKI group had a higher proportion of males(77.3% vs. 53.3%), lower gestational weeks[29(27, 33) weeks vs.31(29, 33)weeks], higher proportions of infants with diabetic mothers(40.9% vs.19.4%), lower Apgar scores at 1 and 5 minutes[8(7, 10) vs.9(8, 10), 9(9, 10) vs.10(9, 10), respectively], higher proportions of invasive and noninvasive respiratory support(45.5% vs.11.3%, 63.6% vs.19.2%, respectively), longer duration of invasive respiratory support[260(136, 742)h vs.72(18, 160)h], longer hospital stays[66(19, 88)d vs.42(26, 58)d], and higher rates of sepsis (27.3% vs. 6.5%), respiratory distress syndrome(40.9% vs. 11.6%), and patent ductus arteriosus that requiring ibuprofen or surgical closure(13.6% vs. 3.0%), diuretic(27.3% vs. 3.9%), and vasoactive drug use (22.7% vs. 3.6%) than those in non-AKI group, and the differences were statistically significant(all P<0.05). Multivariate regression analysis showed that sepsis was an independent risk factor for AKI in preterm infants ( P=0.039, OR=3.498, 95% CI 1.065-11.490) after adjustment of gestational age and birth weight. Conclusion:The incidence of AKI is relatively high in preterm infants with gestational age<28 weeks.Compared with preterm infants without AKI, preterm infants with AKI have smaller gestational weeks and longer hospital stay.Sepsis is an independent risk factor for AKI in preterm infants.

Objective To investigate the expression of LncRNA LINC00857 in pancreatic cells and the effect of lncRNA LINC00857 down-regulation on proliferation, migration and apoptosis of pancreatic cancer PANC-1 cells and possible mechanism. Methods The lentiviral vector GV112 was constructed and infected PANC-1 cells to obtain experimental group, while the blank plasmid was transfected as a negative control group and the cells without intervention were taken as normal control group. CCK-8 assay, Transwell assay, scratch test, flow cytometry, Western blot were used to detect the effect of LINC00857 down-regulation on cell proliferation, migration, apoptosis, cell cycle and EMT-related proteins. Results LINC00857 expression in pancreatic cancer cells were significantly higher than that in normal pancreatic epithelial cells (P < 0.001). Knockdown of LINC00857 could significantly inhibit the proliferation and migration of PANC-1 cells (P < 0.0001); compared with the negative control group, the apoptosis rates of cells in the experimental groups were significantly increased (P < 0.05), the number of cells in G₀/G₁ phase increased (P < 0.01), the number of cells in S phase decreased (P < 0.05), and the cells were blocked in the G₁ phase, E-cadherin expression was significantly up-regulated (P < 0.05) and N-cadherin and Vimentin expression were significantly down-regulated (N-cadherin: P < 0.01, Vimentin: P < 0.05). Conclusion LINC00857 can promote proliferation and migration of PANC-1 cells and inhibit its apoptosis by regulating G₁/S phase transition and EMT signaling pathway.

Lager yeast is the most popular yeast strain used for beer production in China. The flocculation of yeast plays an important role in cell separation at the end of fermentation. Therefore, appropriately enhancing the flocculation capability of the lager yeast without affecting its fermentation performance would be desirable for beer industry. Our previous study showed that the defect of gene RIM21 might contribute to the enhanced flocculation capability of a lager yeast G03. To further investigate the role of the RIM21 gene in flocculation of strain G03, this study constructed a RIM21-deleted mutant strain G03-RIM21Δ through homologous recombination. Deletion of RIM21 improved the flocculation capability of strain G03 during wort fermentation at 11 °C without changing its fermentation performance significantly. The expression of FLO5, Lg-FLO1 and some other genes involved in cell wall integrity pathway were up-regulated in strain G03-RIM21Δ. In addition, the disruption of RIM21 enhanced resistance of yeast cells to cell wall inhibitors. These results provide a basis for elucidating the flocculation mechanism of lager yeast under low-temperature fermentation conditions.

Objective:To explore the efficacy and safety of anti-tumor necrosis factor alpha (TNFα) monoclonal antibodies (mAbs) for severe/refractory vasculo-Behcet′s disease (BD).Method:The clinical data of severe/refractory vasculo-BD patients treated with anti-TNFα mAbs were retrospectively analyzed. Response of anti TNFα mAbs was analyzed. The dosage changes of glucocorticoid, the level of erythrocyte sedimentation rate (ESR) and hypersensitive C-reactive protein (hsCRP) before and after treatment were recorded, as well as side effects.Result:Sixteen patients were enrolled. Arterial lesions were reported in 12 patients, including 9 with arterial aneurysm, 6 with arterial dilation, 2 with stenosis and 2 with occlusion. Seven patients presented venous thrombosis, including lower extremity veins ( n=6), cerebral venous sinus ( n=2) and inferior vena cava system ( n=2). Two cases had both arterial and venous involvement. Before the application of TNFα mAbs, all 16 patients failed to response to prednisone or its equivalent dose of 40 (7.5-90) mg/d in combination with cyclophosphamide, methotrexate, thalidomide or azathioprine for median 4 (0-156) months. After a mean duration of treatment for (17.1±6.5) months, 15 patients achieved complete remission and 1 patient achieved partial remission. Three patients received surgery without any postoperative complications. After using anti TNFα mAbs, the dosage of prednisone [5(0-12.5)mg/d vs. 40(7.5-90)mg/d, P<0.01], ESR [(7.3±4.6) mm/1h vs. (33.5±26.7) mm/1h, P<0.01] and hsCRP [1.9(0.2-11.4) mg/L vs. 24.3(0.4-113.9) mg/L, P<0.01] were significantly decreased. Side effects were observed in 2 patients. One developed pulmonary infection 12 months after adalimumab with conventional treatment. Another patient had allergy to infliximab then switched to adalimumab. Conclusion:In combination with corticosteroids and immunosuppressants, anti-TNF α mAbs are effective and well-tolerated in severe/refractory vasculo-BD, with a favorable steroid -sparing effect and rare postoperative complications.
