Bibliometric analysis of T-cells immunity in pulmonary hypertension from 1992 to 2022.

BACKGROUND: Adaptive immunity is an important disease mediator of pulmonary vascular remodeling during pulmonary hypertension (PH) development, especially T-cells lymphocytes. However, data for bibliometric analysis of T cell immunity in PH is currently vacant. This aimed to provide a comprehensive and visualized view of T-cells research in PH pathogenesis and to lay a solid foundation for further studies. METHODS: The data was acquired from the Web of Science Core Collection database. Web of Science analytic tool was used to analysis the publication years, authors, journals, countries, and organizations. CiteSpace 6.2.R3, VOSviewer 1.6.16, and Scimago Graphica 1.0.35.0 were applied to conduct a visualization bibliometric analysis about authors, countries, institutions, journals, references, and keywords. RESULTS: Nine hundred and eight publications from 1992 to 2022 were included in the analysis. The results showed that Humbert Marc was the most prolific author. American Journal of Physiology Lung Cellular and Molecular Physiology had the most related articles. The institution with the most articles was Udice French Research University. The United States was far ahead in the article output. Keywords analysis showed that "Pulmonary hypertension" was the most usually appeared keyword in the relevant literature, and included "T-cells", "Regulatory T cells", and "Activated T cell." "miRNA" of reference co-citation clustering analysis demonstrated the possible T-cell immunity activation mechanisms in PH. The most cited literature was published in the European Heart Journal by Galie N in 2016. The strongest citation burst of keyword is "gene expression" and terms such as "vascular remodeling," "growth," "proliferation," and "fibrosis" are among the list, indicating that T-cells interact with stromal vascular cells to induce pulmonary vascular remodeling. The strongest burst of cited reference is "Galie N, 2016." CONCLUSIONS: T-cell immunity is an important pathogenesis mechanism for PH development, which may have interaction with miRNAs and stromal vascular cells, but the possible T-cell immunity activation mechanisms in PH need to be investigated further.

Expression of GD2 and GD3 in peripheral neuroblastic tumors.

PURPOSE: The aim of this study was to explore the correlation between the expression of GD2 and GD3 and the histopathological types, risk groups, and chemotherapy in peripheral neuroblastic tumors (pNTs) and provide a theoretical basis for the selection of immunotargeted therapy for pNTs. MATERIALS AND METHODS: The expression of GD2 and GD3 in samples of pNTs in all 87 cases, including 39 neuroblastomas (NB), 13 ganglion neuroblastomas nodular (GNBn), 19 ganglion neuroblastomas intermixed (GNBi), 16 ganglioneuroma (GN), and 16 paired NB after chemotherapy, were detected by immunohistochemistry (IHC). SPSS 20.0 statistical software was used for statistical analysis, and P < 0.05 was considered statistically significant. RESULT: The expression of GD2 was higher than that of GD3 (P < 0.001) in all samples. In NB and GNBn, the expression of GD2 was higher than that of GD3 (P < 0.001 and P = 0.02, respectively). The expression of GD2 in NB was higher than that in GNBn (P = 0.015), and GNBn was higher than GNBi (P < 0.001). The expression of GD2 in the high-risk group was significantly higher than that in the medium-risk group and low-risk group (P = 0.019). The expression of GD2 before chemotherapy was higher than that after chemotherapy (P = 0.022). GD2 was expressed in different degrees in tumor-infiltrating lymphocytes. CONCLUSION: GD2 may be better than GD3 as a target of immunotherapy for pNTs, especially in the same pathological type. NB and GNBn may be more suitable for anti-GD2 immunotherapy. The expression of GD2 on tumor-infiltrating lymphocytes may be related to the side effects of anti-GD2 immunotherapy.

Bibliometric analysis of mucosal immunity in IgA nephropathy from 1990 to 2022.

OBJECTIVE: The study aimed to conduct a bibliometric analysis of mucosal immunity in IgA nephropathy (IgAN) and indicate its current status, hot sopts, and direction of future studies. METHODS: The literature data was collected from the Web of Science Core Collection. CiteSpace 6.1.R3 was employed to conduct a visualization bibliometric analysis of mucosal immunity in IgA nephropathy, including authors, countries, journals, keywords, organizations, references, the bursts of keywords and references, and the timeline of keyword clusters and reference clusters. RESULTS: A total of 315 publications from 1990 to 2022 were included. The number of articles in this field has increased in recent years. Suzuki H, Coppo R, and Feehally J took the first place parallelly with 18 articles. Japan contributes the most articles, accounting for 27.3% of all the publications. The institutions with the most publications were Juntendo University and University of Alabama Birmingham. 453 keywords were concluded in the analysis, which mainly focus on the mucosal pathogenesis and therapy of the IgAN. The top five co-cited reference cluster are "aberrantly glycosylated IgA," "corticosteroids," "animal models," "o-glycosylationm" and "microRNA-630." The most recently burst of keyword is "tonsillectomy" and "gut." CONCLUSION: This was the first bibliometric analysis to systematically analyze the mucosal immunity in IgAN, which obtained the current status and indicated the future research hotspots and development trends. The gut microbiota and the related therapy-targeted mucosal immunity might be the future research hotspot.

Cut-off values of haemoglobin and clinical outcomes in incident peritoneal dialysis: the PDTAP study.

BACKGROUND: To explore the cut-off values of haemoglobin (Hb) on adverse clinical outcomes in incident peritoneal dialysis (PD) patients based on a national-level database. METHODS: The observational cohort study was from the Peritoneal Dialysis Telemedicine-assisted Platform (PDTAP) dataset. The primary outcomes were all-cause mortality, major adverse cardiovascular events (MACE) and modified MACE (MACE+). The secondary outcomes were the occurrences of hospitalization, first-episode peritonitis and permanent transfer to haemodialysis (HD). RESULTS: A total of 2591 PD patients were enrolled between June 2016 and April 2019 and followed up until December 2020. Baseline and time-averaged Hb <100 g/l were associated with all-cause mortality, MACE, MACE+ and hospitalizations. After multivariable adjustments, only time-averaged Hb <100 g/l significantly predicted a higher risk for all-cause mortality {hazard ratio [HR] 1.83 [95% confidence interval (CI) 1.19-281], P = .006}, MACE [HR 1.99 (95% CI 1.16-3.40), P = .012] and MACE+ [HR 1.77 (95% CI 1.15-2.73), P = .010] in the total cohort. No associations between Hb and hospitalizations, transfer to HD and first-episode peritonitis were observed. Among patients with Hb ≥100 g/l at baseline, younger age, female, use of iron supplementation, lower values of serum albumin and renal Kt/V independently predicted the incidence of Hb <100 g/l during the follow-up. CONCLUSION: This study provided real-world evidence on the cut-off value of Hb for predicting poorer outcomes through a nation-level prospective PD cohort.

Pegmolesatide for the treatment of anemia in patients undergoing dialysis: a randomized clinical trial.

Background: Pegmolesatide, a synthetic peptide-based erythropoietin (EPO) receptor agonist, is being evaluated as an alternative to epoetin alfa for treating anemia of chronic kidney disease (CKD) in Chinese dialysis patients. There is a critical need for a long-acting, cost-effective erythropoiesis-stimulating agent that does not produce EPO antibodies. Methods: A randomized, open-label, active-comparator, non-inferiority phase three trial was conducted at 43 dialysis centers in China between May 17th, 2019, and March 28th, 2022. Eligible patients aged 18-70 years were randomly assigned (2:1) to receive pegmolesatide once every four weeks or epoetin alfa one to three times per week, with doses adjusted to maintain a hemoglobin level between 10.0 and 12.0 g/dL. The primary efficacy endpoint was the mean change in hemoglobin level from baseline to the efficacy evaluation period in the per-protocol set (PPS) population. Non-inferiority of pegmolesatide to epoetin alfa was established if the lower limit of the two-sided 95% confidence interval for the between-group difference was ≥ -1.0 g/dL. Safety assessment included adverse events and potential anaphylaxis reactions. This trial is registered at ClinicalTrials.gov, NCT03902691. Findings: Three hundreds and seventy-two patients were randomly assigned to the pegmolesatide group (248 patients) or the epoetin alfa group (124 patients). A total of 347 patients (233 in the pegmolesatide group and 114 in the epoetin alfa group) were included in the PPS population. In the PPS, the mean change (standard deviation, SD) in hemoglobin level from baseline to the efficacy evaluation period was 0.07 (0.92) g/dL in the pegmolesatide group and -0.22 (0.97) g/dL in the epoetin alfa group. The between-group difference was 0.29 g/dL (95% confidence interval: 0.11-0.47), verifying non-inferiority of pegmolesatide to epoetin alfa. Adverse events occurred in 231 (94%) participants in the pegmolesatide group and in 110 (89%) in the epoetin alfa group. Hypertension was the most common treatment-related adverse event. No fatal cases of anaphylaxis or hypotension were reported. Interpretation: Monthly subcutaneously injection of pegmolesatide was as effective and safe as conventional epoetin alfa administrated one to three times a week in treating anemia in Chinese dialysis patients. Funding: The study was supported by Hansoh Medical Development Group.

Combination of Rituximab and Low-dose Tacrolimus in the Treatment of Refractory Membranous Nephropathy: A Retrospective Cohort Study

Background: Conventional regimens for refractory idiopathic membranous nephropathy (IMN) still have limitations. Rituximab (RTX) has a good effect in the treatment of refractory IMN. However, whether RTX single or combined with immunosuppressive therapy is more effective and whether adverse events will increase are still inconclusive. Aims: To investigate the efficacy and safety of RTX combined with low-dose tacrolimus (TAC) versus RTX alone in the treatment of refractory IMN. Study Design: A retrospective cohort study. Methods: We retrospectively studied 91 cases of refractory IMN diagnosed between January 2018 and June 2021, all of which immunosuppressive regimens had failed. Thirty-four patients received RTX combined with TAC (RTX + TAC group), and 57 patients were treated with RTX alone (RTX group). The RTX + TAC group was given RTX 1 g once every 2 weeks, two times, and TAC 0.03 mg/kg/day orally. In the RTX group, RTX was given at the same dosage as the RTX + TAC group. Clinical data were collected at 12 months of follow-up to compare the complete and partial remission rates and the incidence of adverse reactions between the two groups. Results: The overall effectiveness rate of RTX + TAC in the treatment of refractory IMN was 87.14%, of which the partial and complete remission rates were 50.01% and 37.13%, respectively, and the median time to complete remission was 9 (interquartile range [IQR] 6.0, 12.0) months. The overall effectiveness rate of RTX was 65.87%, of which the partial and complete remission rates were 39.48% and 26.39%, respectively, and the median time to complete remission was 10.5 (IQR 6.0, 12.0) months. Adverse events occurred in 6 (17.65%) patients in the RTX + TAC group and in 11 (19.30%) in the RTX group (P = 0.473). Proteinuria and high titer of PLA2R are risk factors for non-remission. Conclusion: The complete and partial remission rates of RTX combined with low-dose TAC in the treatment of refractory IMN are higher than those of RTX alone, and no significant increase in adverse events was noted.

Efficacy and Safety of Sevelamer Carbonate in Chinese Nondialysis Chronic Kidney Disease Patients with Hyperphosphatemia: A Randomized, Double-Blind, Parallel-Group Study.

Introduction: Previous studies suggested that sevelamer carbonate is well tolerated with a favorable efficacy and safety profile in both dialysis and nondialysis patients in Europe; however, the efficacy remains controversial, and few studies have examined sevelamer carbonate therapy in other ethnic nondialysis CKD patients. This study assessed the efficacy and safety of sevelamer carbonate in Chinese nondialysis CKD patients with hyperphosphatemia. Methods: The multicenter, randomized, double-blind, parallel-group, placebo-controlled, and phase 3 clinical trial enrolled 202 Chinese nondialysis CKD patients with serum phosphorus ≥1.78 mmol/L. Patients were randomly assigned 1:1 to receive sevelamer carbonate (2.4-12 g per day) or placebo for 8 weeks. The primary outcome was the change in serum phosphorous between baseline and week 8. Results: Totally 482 Chinese patients were screened and 202 were randomized (sevelamer carbonate, n = 101; placebo, n = 101). The mean serum phosphorous decreased significantly in patients treated with sevelamer carbonate compared with placebo (-0.22 ± 0.47 vs. 0.05 ± 0.44 mmol/L, p < 0.0001). Significantly (p < 0.0001), decreases of serum total cholesterol, low-density lipoprotein cholesterol, and calcium-phosphorus (Ca × P) product levels from baseline to week 8 were shown in sevelamer carbonate group compared with placebo group. Serum intact parathyroid hormone was not significantly changed in the sevelamer carbonate group (p = 0.83). Patients in the sevelamer carbonate group experienced similar adverse events as the placebo group. Conclusion: Sevelamer carbonate is an effective and well-tolerated phosphate binder in advanced nondialysis CKD Chinese patients with hyperphosphatemia.

How the home learning environment contributes to children's social-emotional competence: A moderated mediation model.

Introduction: The home learning environment is the earliest contact learning environment in early childhood development, which plays an important role in the development of children's social-emotional competence. However, previous studies have not clarified the precise mechanisms by which the home learning environment influences children's social-emotional competence. Therefore, the purpose of the study is to explore the relationship between the home learning environment and its intrinsic structure (i.e. structural family characteristics, parental beliefs and interests, and the educational processes) and children's social-emotional competence, and whether gender plays a moderating role in the relationship. Method: The study randomly selected a sample of 443 children from 14 kindergartens in western China. The Home Learning Environment Questionnaire and the Chinese Inventory of Children's Social-emotional competence scale were used to investigate the home learning environment and social-emotional competence of these children. Results: (1) Structural family characteristics and parental beliefs and interests both had a significant positive predictive effect on children's social-emotional competence. (2) The educational processes fully mediate between structural family characteristics, parental beliefs and interests, and children's social-emotional competence. (3) Gender moderated the effect of the home learning environment on children's social-emotional competence. Gender moderates not only the indirect effects between parental beliefs and interests and children's social-emotional competence, but also the indirect effects between structural family characteristics and children's social-emotional competence. At the same time, gender also moderated the direct effects between parental beliefs and interests and children's social-emotional competence. Discussion: The results emphasize the crucial role of the home learning environment in the development of children's early social-emotional competence. Therefore, parents should pay attention to the home learning environment and improve their ability to create a home learning environment that promotes the positive development of children's social-emotional competence.

Infant-Type Hemispheric Glioma in a Chinese Girl: A Newly Defined Entity.

BACKGROUND: Infant-type hemispheric glioma is a newly defined entity in the updated 2021 WHO classification of tumors of the central nervous system. This lesion occurs in the cerebral hemispheres of newborns and infants and harbors molecular alterations in the NTRK family, ALK, ROS, or MET. Case report: A four-month-old female infant presented with a large space occupying lesion of the left cerebral hemisphere, whose histological manifestation was high-grade hemispheric infantile glioma. Tumor expressed panTRK, indicative of rearranged NTRK1, which was validated by next generation sequencing (NGS) as TPM3-NTRK1 fusion. There was homozygous deletion of CDKN2A/B, and there were ROS1, TLX3, FAT1, ABL1, MSH2, and PALB2 mutations. Conclusion: The additional genetic alterations in this case may expand the genotypic spectrum of this distinct cohort.

Primary resistance to first- and second-generation ALK inhibitors in a non-small cell lung cancer patient with coexisting ALK rearrangement and an ALK F1174L-cis-S1189C de novo mutation: A case report.

The effectiveness of the tyrosine kinase inhibitor ALK (TKI) for non-small cell lung cancer has been confirmed. However, resistance to ALK-TKIs seems inevitable. Mutations in the ALK kinase domain have been reported as an important mechanism of acquired resistance to ALK therapy. However, patients with de novo ALK kinase domain mutations and ALK rearrangements who were not treated with ALK inhibitors have rarely been reported. Here, we report a case of primary drug resistance to first- and second-generation ALK inhibitors in a NSCLC patient with ALK-rearrangement. The next-generation sequencing test of the pathological biopsy showed that the de novo ALK kinase domain mutation F1174L-cis-S1189C may be the cause of primary drug resistance.

Prognostic effect of pulmonary hypertension in patients with chronic kidney disease: Univariate and multivariate analyses of factors associated with survival.

Background: Prognostic effect of pulmonary hypertension (PH) in patients with chronic kidney disease (CKD) is not fully clear yet, this study was designed to elucidate baseline characteristics of CKD patients with different severities of PH, the association between kidney indicators and PH severity, and survival factors in CKD patients with PH. Methods: We extracted clinical data from electronic medical records of all patients diagnosed with PH in CKD from Jan 2016 to Dec 2020, and those with comorbid conditions causing PH were excluded. CKD stages were defined by estimated glomerular filtration rate thresholds. PH was defined as a systolic pulmonary artery pressure (sPAP) >35 mmHg estimated using echocardiograms. Demographics, clinical data, and test results were analyzed, and all-cause mortality data were obtained. Results: A total of 137 patients were included in the study. The mean age of the participants was 60 (42.5, 67) years, the mean sPAP was 58 (51, 69.5) mmHg, and 40.9% of the patients were women. Moderate PH group had more patients undergoing dialysis and higher frequency of coronary heart disease. Moderate-severe PH group had higher parathyroid hormone levels and lower low-density lipoprotein levels. Severe PH group had better kidney function parameters and lower serum phosphorus levels. PH severity had no direct relationship with CKD stages. In the univariate analysis, age and PH severity influenced survival. Multivariate analysis also showed independent prognostic effects for age and sPAP. Kaplan-Meyer curve intuitively displayed the survival differences among CKD patients with different PH severity. Predictor values of nomogram identified from survival analyses enabled calculation of death probabilities for CKD with PH patients. Nomogram was validated by ROC analysis. Conclusions: PH begins with early-stage CKD, and PH severity is not related to CKD progression. A higher pulmonary artery pressure and an older age are associated with an increased risk of death.

A scoring model for diagnosis of tuberculous pleural effusion.

BACKGROUND: Due to the low efficiency of a single clinical feature or laboratory variable in the diagnosis of tuberculous pleural effusion (TBPE), the diagnosis of TBPE is still challenging. This study aimed to build a scoring diagnostic model based on laboratory variables and clinical features to differentiate TBPE from non-tuberculous pleural effusion (non-TBPE). METHODS: A retrospective study of 125 patients (63 with TBPE; 62 with non-TBPE) was undertaken. Univariate analysis was used to select the laboratory and clinical variables relevant to the model composition. The statistically different variables were selected to undergo binary logistic regression. Variables B coefficients were used to define a numerical score to calculate a scoring model. A receiver operating characteristic (ROC) curve was used to calculate the best cut-off value and evaluate the performance of the model. Finally, we add a validation cohort to verify the model. RESULTS: Six variables were selected in the scoring model: Age ≤ 46 years old (4.96 points), Male (2.44 points), No cancer (3.19 points), Positive T-cell Spot (T-SPOT) results (4.69 points), Adenosine Deaminase (ADA) ≥ 24.5U/L (2.48 point), C-reactive Protein (CRP) ≥ 52.8 mg/L (1.84 points). With a cut-off value of a total score of 11.038 points, the scoring model's sensitivity, specificity, and accuracy were 93.7%, 96.8%, and 99.2%, respectively. And the validation cohort confirms the model with the sensitivity, specificity, and accuracy of 92.9%, 93.3%, and 93.1%, respectively. CONCLUSION: The scoring model can be used in differentiating TBPE from non-TBPE.

Case Report: A good response to furmonertinib second-line treatment of an advanced lung adenocarcinoma patient with a rare EGFR exon 20 N771_P772insH mutation: A case report and literature review.

Background: Lung adenocarcinoma with the classical EGFR 19 deletion and exon 21 L858R point mutations has exhibited good responses to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) treatment. However, the sensitivity of uncommon EGFR exon 20 insertion mutation to third-generation EGFR-TKIs has not been determined. Although emerging targeted therapies for EGFR exon 20 insertion mutation have been reported in recent years, such patients still have a poorer prognosis than those with typical or wild-type EGFR mutations. Case summary: Here, we report the case of a 57-year-old man with advanced non-small cell lung cancer (NSCLC) with a rare EGFR exon 20 N771_P772insH mutation. The patient was treated with furmonertinib as second-line therapy. Although his pleural effusion was more than before that during treatment, various examination results showed that the pleural effusion was closely related to hypoproteinemia; thus, local progression was not considered. His cough was significantly alleviated, and the dose was well tolerated. The patient was evaluated for a remarkable progression-free survival (PFS) of 10.0 months, a duration of response (DOR) of 8.0 months, and an overall survival (OS) of 22.0 months, which had not previously been achieved. Conclusion: The present study indicated that furmonertinib might be a good treatment option for first-line progressive NSCLC patients with EGFR exon 20 insertion mutation.

Telemedicine and Clinical Outcomes in Peritoneal Dialysis: A Propensity-Matched Study.

INTRODUCTION: Telemedicine (TM) has shown to provide potential benefits on clinical outcomes in patients with chronic kidney disease but limited evidences published in the peritoneal dialysis (PD) population. This study aimed to explore the long-term effects of TM on the mortality and technique failure. METHODS: The Peritoneal Dialysis Telemedicine-assisted Platform Cohort Study (PDTAP Study) was conducted prospectively in 27 hospitals in China since 2016. Patient and practice data were collected through the doctor-end of the TM app (Manburs) for all participants. TM including self-monitoring records, on-line education materials, and real-time physician-patient contact was only performed for the patient-end users of the Manburs. The primary outcome was all-cause mortality. The secondary outcomes were cause-specific mortality and all-cause and cause-specific permanent transfer to hemodialysis. RESULTS: A total of 7,539 PD patients were enrolled between June 2016 and April 2019, with follow-up till December 2020. Patients were divided into two cohorts: TM group (39.1%) and non-TM group (60.9%). A propensity score was used to create 2,160 matched pairs in which the baseline covariates were well-balanced. There were significantly lower risks of all-cause mortality (HR 0.59 [0.51, 0.67], p < 0.001), CVD mortality (HR 0.59 [0.49, 0.70], p < 0.001), all-cause transfer to hemodialysis (0.57 [0.48, 0.67], p < 0.001), transfer to hemodialysis from PD-related infection (0.67 [0.51, 0.88], p = 0.003), severe fluid overload (0.40 [0.30, 0.55], p < 0.001), inadequate solute clearance (0.49 [0.26, 0.92], p = 0.026), and catheter-related noninfectious complications (0.41 [0.17, 0.97], p = 0.041) in the TM group compared with the non-TM group. CONCLUSION: This study indicated real-world associations between TM usage and reduction in patient survival and technique survival through a multicenter prospective cohort.

Revealing the impacts on shaping scutate scales in goose skin.

Feather follicles and scales are two types of skin appendages distributed on different parts of avian skin. The morphogenesis and development of scales in waterfowl remain largely unknown. Here, we used H&E staining, ISH and RNA sequencing to reveal the morphological and molecular variations at the early development of scutate scales in goose shank skin. Transcriptome analysis produced 1824 differentially expressed genes (DEGs) regulating the induction of scales and further enriched gene function in cell adhesion and Wnt signaling pathway, etc. A total of 8 candidate genes (ALDOC, CSRP2, KRT15, KRT75, LGALS1, S100A6, OGN and SFRP2) were further detected by RT-qPCR to show upregulated (6 genes) and downregulated (2 genes) from pre-placodal to placode stage during the induction of goose scales. The localization of 7 candidate genes (ALDOC, CSRP2, CD109, KRT15, KRT75, S100A6, and OGN) by ISH suggests the potential roles for dermal and epidermal development during the induction of scutate scales. The dynamic molecular changes and specific gene expression patterns revealed in this report provide general knowledge of scale development in waterfowl as well as skin appendage diversity.

New Formulation to Accelerate the Degradation of Pesticide Residues: Composite Nanoparticles of Imidacloprid and 24-Epibrassinolide.

Pest control effectiveness and residues of pesticides are contradictory concerns in agriculture and environmental conservation. On the premise of not affecting the insecticidal effect, the pesticide residues in the later stage should be degraded as fast as possible. In the present study, composite nanoparticles in a double-layer structure, consisting of imidacloprid (IMI) in the outer layer and plant hormone 24-epibrassinolide (24-EBL) in the inner layer, were prepared by the W/O/W solvent evaporation method using Eudragit RL/RS and polyhydroxyalkanoate as wall materials. The release of IMI in the outer layer was faster and reached the maximum within 24 h, while the release of 24-EBL in the inner layer was slower and reached the maximum within 96 h. The contact angle of the composite nanoparticles was half that of the 5% IMI emulsifiable concentrate (EC), and the deposition of composite nanoparticles on rice was twice that of 5% IMI EC, which increased the pesticide utilization efficiency. Compared with the common pesticide, 5% IMI EC, the insecticidal effect of the composite nanoparticles was stronger than that of planthoppers, with a much lower final residue amount on rice after 21 days. The composite nanoparticles prepared in this study to achieve sustained release of pesticides and, meanwhile, accelerate the degradation of pesticide residues have a strong application potential in agriculture for controlling pests and promoting crop growth.

Recent advances in bronchial thermoplasty for severe asthma: a narrative review.

Background and Objective: Severe asthma refers to asthma that requires step 4 or 5 therapy recommended by Global Initiative for Asthma (GINA) to prevent it from becoming uncontrolled or remaining "uncontrolled" despite this therapy. The poor treatment effect of severe asthma has been perplexing clinicians, which reduces the quality of life (QoL) of patients with asthma, and increases the mortality of such patients, so improving the therapeutic effect of severe asthma is an urgent problem to be solved in the clinic. Bronchial thermoplasty (BT) is a new non-drug therapy for severe asthma that is difficult to control with medications. It has been approved for clinical practice in China and the United States. The article aims at providing a new treatment option for patients with severe asthma that is poorly controlled by medications, thus improving the QoL in these patients. Methods: An extensive literature search was performed in the PubMed database, with "bronchial thermoplasty" as the key term. The full texts of all potentially relevant articles were obtained, and relevant information was extracted. Key Content and Findings: We find that BT is suitable for patients with severe asthma poorly controlled by medications. Conclusions: This paper reviews the mechanism of action, procedure, safety and effectiveness, adverse effects and complications, problems, and prospects of BT, with an attempt to guide the practical application of this technique.

TMEM199-Congenital Disorder of Glycosylation With Novel Phenotype and Genotype in a Chinese Boy.

Background: TMEM199-congenital disorder of glycosylation (TMEM199-CDG) is a rare autosomal recessive inherited disease characterized by chronically elevated serum transaminase, decreased serum ceruloplasmin, steatosis and/or fibrosis, TMEM199 mutation, reduced level of TMEM199 protein, and abnormal protein glycosylation. Methods: The information of a Chinese patient with TMEM199-CDG in the Children's Hospital of Fudan University was reviewed. The patient's clinical, pathological, and molecular features were obtained by clinical data study, liver biopsy, immunohistochemistry, and molecular genetic analysis. Results: A 4-year-old Chinese boy presented with hypertransaminasemia, hypercholesterolemia, elevated alkaline phosphatase, decreased serum ceruloplasmin and serum copper level, and coagulopathy since birth. To the best of our knowledge, novel findings included strabismus, cirrhosis by liver biopsy, reduced expression of TMEM199 by immunohistochemistry, and a frameshift variant of c.128delA/p.Lys43Argfs*25 in the TMEM199 gene. Conclusion: This case added to the phenotypic and genotypic spectrum of TMEM199-CDG.

Effect of Tacrolimus vs Intravenous Cyclophosphamide on Complete or Partial Response in Patients With Lupus Nephritis: A Randomized Clinical Trial.

Importance: Lupus nephritis (LN) is typically treated with intravenous cyclophosphamide (IVCY), which is associated with serious adverse effects. Tacrolimus may be an alternative for initial treatment of LN; however, large-scale, randomized clinical studies of tacrolimus are lacking. Objective: To assess efficacy and safety of tacrolimus vs IVCY as an initial therapy for LN in China. Design, Setting, and Participants: This randomized (1:1), open-label, parallel-controlled, phase 3, noninferiority clinical trial recruited patients aged 18 to 60 years with systemic lupus erythematosus and LN class III, IV, V, III+V, or IV+V primarily from outpatient settings at 35 centers in China. Inclusion criteria included body mass index of 18.5 or greater to less than 27, 24-hour urine protein of 1.5 g or greater, and serum creatinine of less than 260 µmol/L. Of 505 patients screened, 191 failed screening (163 ineligible, 25 withdrawn consent, and 3 other reasons). Overall, 314 were randomized. The first patient was enrolled March 10, 2015, and the study finished September 13, 2018. The follow-up period was 24 weeks. Data were analyzed from December 2019 to March 2020. Interventions: Oral tacrolimus (target trough level, 4-10 ng/mL) or IVCY for 24 weeks plus prednisone. Main Outcomes and Measures: Complete or partial response rate at week 24 (prespecified). Results: A total of 314 patients were randomized (158 [50.3%] to tacrolimus and 156 [49.7%] to IVCY). Overall, 299 patients (95.2%) were treated (tacrolimus group, 157 [52.5%]; IVCY group, 142 [47.5%]). Baseline demographic and clinical characteristics were generally similar between groups (mean [SD] age, 34.2 [9.5] years; 262 [87.6%] female). Tacrolimus was found to be noninferior to IVCY for LN response at week 24. There was a complete or partial response rate of 83.0% (117 of 141 patients) in the tacrolimus group and 75.0% (93 of 124 patients) in the IVCY group (difference, 7.1%; 2-sided 95% CI, -2.7% to 16.9%; lower limit of 95% CI greater than -15%). At week 24, least-square mean change in Systemic Lupus Erythematosus Disease Activity Index score was -8.6 with tacrolimus and -6.4 with IVCY (difference, -2.2; 95% CI, -3.1 to -1.3). Changes in other immune parameters and kidney function were generally similar between groups. Serious treatment-emergent adverse events (TEAEs) were reported in 29 patients in the tacrolimus group (18.5%) and 35 patients in the IVCY group (24.6%). Most common serious study drug-related TEAEs were infections (14 [8.9%] and 23 [16.2%], respectively). Seven patients in each group withdrew due to AEs. Conclusions and Relevance: In this study, oral tacrolimus appeared noninferior to IVCY for initial therapy of active LN, with a more favorable safety profile than IVCY. Tacrolimus may be an alternative to IVCY as initial therapy for LN. Trial Registration: ClinicalTrials.gov Identifier: NCT02457221.
