Objective:To compare the efficacy and safety of biologics versus methotrexate in the treatment of severe pediatric plaque psoriasis.Methods:A retrospective matched case-control study was carried out. Twenty children with severe plaque psoriasis from Beijing Children′s Hospital, Capital Medical University from June 2016 to November 2021 were included in this study, and the patients treated with biologics (adalimumab or secukinumab) were matched with those treated with methotrexate at a ratio of 1∶1 according to the psoriasis area and severity index (PASI) score and age. PASI, physician′s global assessment (PGA) , and body surface area (BSA) scores were assessed at weeks 4, 8 and 12 after the start of treatment, and adverse drug reactions were recorded. Statistical analysis was mainly carried out by using Mann-Whitney U test, Fisher′s exact test and generalized estimating equations. Results:At weeks 4 and 8, the proportions of patients achieving PASI75 and PASI90 were significantly higher in the biologics group (PASI75: 7/10, 10/10, PASI90: 5/10, 9/10, respectively) than in the methotrexate group (PASI75: 1/10, 5/10, PASI90: 0, 1/10, respectively; all P < 0.05) , while there was no significant difference between the biologics group and methotrexate group at week 12 (PASI75: 10/10 vs. 8/10, PASI90: 9/10 vs. 4/10, both P > 0.05) . There were no significant differences in the PASI, BSA or PGA scores between the two groups at baseline (all P > 0.05) , while the biologics group showed significantly decreased PASI and BSA scores at weeks 4, 8 and 12, and significantly decreased PGA score at week 8 compared with the methotrexate group (PASI: Z = 2.50, 3.56, 2.63, respectively; BSA: Z = 2.87, 3.57, 2.40, respectively; PGA: Z = 2.81; all P<0.05) . Analysis of changes over time showed that the PASI, PGA and BSA scores in the biologics group significantly decreased at weeks 4, 8 and 12 compared with those at baseline (all P<0.01) ; the PASI and PGA scores significantly decreased at weeks 8 and 12 compared with the corresponding scores at week 4 (all P<0.05) ; however, there were no significant differences in the PASI, PGA or BSA scores between week 12 and 8 (all P>0.05) . In the methotrexate group, the PASI, PGA and BSA scores at weeks 4, 8 and 12 were all significantly lower than the corresponding scores at the previous adjacent time points (all P<0.05) . There was no significant difference in the incidence of adverse reactions between the two groups ( P = 0.650) , and no serious adverse reactions occurred in either group. The main adverse reaction was infection in the biologics group, while infection and elevation of transaminase levels were common in the methotrexate group. Conclusion:Biologics and methotrexate were both effective and safe for the treatment of severe pediatricplaque psoriasis, and biologics facilitated rapider achievement of PASI75 and PASI90 compared with methotrexate.

Rapamycin is a mammalian target of rapamycin(mTOR) receptor inhibitor. Advances in the understanding of the mTOR signaling pathway and its downstream effects on tumorigenesis and vascular proliferation have broadened the clinical applications of mTOR receptor inhibitors in treating many challenging diseases. Rapamycin is used orally for the treatment of kidney transplantation, lymphatic leiomyomatosis of lung, tuberous sclerosis complex(TSC), and etc. But systemic therapy using the rapamycin has significant side effects. To mitigate the side effects of systemic rapamycin for dermatologic applications, clinicians have used topical therapy. In recent years, research publications on the topical rapamycin in the treatment of a variety of diseases have increased, as on such diseases of facial angiofibroma of tuberous sclerosis complex, lymphatic malformation, Kaposi hemangioendothelioma, tufted angiomas, and etc. Topical rapamycin can be used as an effective long-term therapy while avoiding systemic side effects, providing a new treatment method for dermatologists. This paper discusses the progress in the treatment of topical rapamycin preparations.

Objective:To effectively express the receptor binding domain (RBD) of SARS-CoV-2 spike protein in Pichia pastoris and to evaluate its immunogenicity. Methods:The gene encoding the RBD protein was synthesized and cloned into the pPICZαA plasmid. After linearization, the plasmid was transferred and integrated into the genome of Pichia pastoris. The expressed RBD protein in culture supernatant was analyzed by Western blot and Biolayer interferometry. After screening, a single clone expressing the RBD protein was selected. The high-level expression of RBD protein was achieved by optimizing the fermentation process, including the salt concentration adjusting of the medium and induction condition optimization (pH, temperature and duration). The immunogenicity of the expressed RBD protein was evaluated in a mouse model. Results:A single clone with a high expression level of RBD protein was obtained and named RBD-X33. The expression level of RBD protein in the fermentation supernatant reached up to 240 mg/L after optimization of the induction condition (HBSM medium, pH=6.5±0.3, 22℃ and 120 h). In the mouse experiment, the recombinant RBD protein was formulated with Alum+ CpG dual adjuvant and injected into mice. The binding IgG antibody levels were up to 2.7×10 6 tested by ELISA and the neutralizing antibody levels were up to 726.8 tested by live virus neutralizing antibody assay (prototype). Conclusions:The RBD protein could be efficiently expressed in Pichia pastoris and induce stronger immune response in animals. This study suggested that the recombinant SARS-CoV-2 RBD protein expressed in Pichia pastoris could serve as a candidate antigen in the development of SARS-CoV-2 vaccine.

Objective:To compare the growth speed of pulmonary artery and left ventricle after the repair of tetralogy of Fallot(TOF) with valve-sparing and transannular patch.Methods:The clinical data of children with tetralogy of Fallot admitted to our hospital from January 2015 to October 2020 were reviewed. According to the way of relieving right ventricular outflow tract stenosis, they were divided into two groups: valve-sparing and transannular patch. Independent sample t test or non- parametric test was used to compare the pulmonary artery and left ventricular growth indexes before operation and at the last follow-up between the two groups. The paired t test was used to compare preoperative and postoperative indexes. Results:A total of 104 children with tetralogy of Fallot, including 58 males and 46 females, had surgery at a median age and weight of 6.7(4.1, 10.3) months and 7.0(5.8, 8.4) kg, respectively. The preoperative Nakata index, McGoon ratio, pulmonary artery Z-score, left ventricular end diastolic volume(LVEDV) index and Z-score in valve-sparing were higher than those in transannular patch( P=0.001, 0.000, 0.003, 0.000, 0.000). At the last follow-up, the Z-scores of pulmonary arteries in both groups were greater than those before operation( P=0.016, 0.000), the LVEDV Z-score in transannular patch was greater than that before surgery( P=0.000), while the LVEDV Z-score of valve-sparing was not significantly different from that before operation( P=0.581), there was no significant difference in pulmonary artery Z-score and LVEDV Z-score between two groups( P=0.468, 0.884). The difference between the last follow-up and preoperative of pulmonary artery Z-score and LVEDV Z-score in valve-sparing was smaller than that in transannular patch( P=0.000, 0.000). Conclusion:Compared with valve-sparing, the pulmonary artery and left ventricle grow faster in transannular patch during the early stage after TOF repair.

Objective To summarize the experience and lessons of right ventricular decompression in children with pulmonary atresia and intact ventricular septum (PA/IVS) and to reflect on the strategies of right ventricular decompression. Methods The clinical data of 12 children with PA/IVS who underwent right ventricular decompression in our hospital from March 2015 to December 2019 were reviewed retrospectively. There were 10 males and 2 females with a median age at the time of surgery was 5 d (range, 1-627 d). Correlation analysis between the pulmonary valve transvalvular pressure gradient and changes in Z score of tricuspid valves after decompression was performed. Results One patient died of refractory hypoxemia due to circulatory shunt postoperatively and family members gave up treatment. There were 2 (16.67%) patients received postoperative intervention. The pulmonary transvalvular gradient after decompression was 31.95±21.75 mm Hg. Mild pulmonary regurgitation was found in 7 patients, moderate in 2 patients, and massive in 1 patient. The median time of mechanical ventilation was 30.50 h (range, 6.00-270.50 h), and the average duration of ICU stay was 164.06±87.74 h. The average postoperative follow-up time was 354.82±331.37 d. At the last follow-up, the average Z score of tricuspid valves was 1.32±0.71, the median pressure gradient between right ventricle and main pulmonary artery was 41.75 mm Hg (range, 21-146 mm Hg) and the average percutaneous oxygen saturation was 92.78%±3.73%. Two children underwent percutaneous balloon pulmonary valvoplasty at 6 and 10 months after surgery, respectively, with the rate of reintervention-free of 81.8%. There was no significant correlation between pulmonary transvalvular gradients after decompression and changes in Z score of tricuspid valves (r=–0.506, P=0.201). Conclusion For children with PA/IVS, the simple pursuit of adequate decompression during right ventricular decompression may lead to severe pulmonary dysfunction, increase the risk of ineffective circular shunt, and induce refractory hypoxemia. The staged decompression can ensure the safety and effectiveness for initial surgery and reduce the risk of postoperative death.
