Physical growth and neurodevelopment of preterm infants at the corrected age of 18-24 months / 中国当代儿科杂志

OBJECTIVES@#To investigate the levels of physical growth and neurodevelopment in preterm infants at the corrected age of 18-24 months.@*METHODS@#The physical growth data and neurodevelopment data of 484 preterm infants at corrected age of 18-24 months were prospectively collected by a post-discharge follow-up system for preterm infants. The infants were regularly followed up in Shenzhen Bao'an Maternal and Child Health Hospital Affiliated to Jinan University from April 2018 to December 2021. The neurodevelopment was evaluated by the Children Neuropsychological and Behavioral Scale-Revision 2016. A total of 219 full-term infants served as controls. The infants were divided into groups (extremely preterm, very preterm, moderate late preterm, and full-term) based on gestational age, and the groups were compared in the levels of physical growth and neurodevelopment.@*RESULTS@#Except that the moderate preterm group had a higher length-for-age Z-score than the full-term group (P=0.038), there was no significant difference in physical growth indicators between the preterm groups and the full-term group (P>0.05). Each preterm group had a significantly lower total developmental quotient (DQ) than the full-term group (P<0.05). Except for the social behavior domain, the DQ of other domains in the extremely preterm and very preterm groups was significantly lower than that in the full-term group (P<0.05). The <32 weeks preterm group had a significantly higher incidence rate of global developmental delay than the full-term group (16.7% vs 6.4%, P=0.012), and the incidence rate of global developmental delay tended to increase with the reduction in gestational age (P=0.026).@*CONCLUSIONS@#Preterm infants can catch up with full-term infants in terms of physical growth at the corrected age of 18-24 months, but with a lower neurodevelopmental level than full-term infants. Neurodevelopment monitoring and early intervention should be taken seriously for preterm infants with a gestational age of <32 weeks.

In 180 patients, 18 cases developed two hematologic malignancies successively, and 11 patients developed more than 3 primary cancers (among them, 2 female patients were diagnosed with 4 primary cancers). Patients with lymphoma and multiple myeloma (MM) as the second primary malignancy had poorer survival than patients with lymphoma and MM as the first primary malignancy. Patients with chronic myeloid leukemia as the second primary malignancy were also associated with inferior overall survival.@*CONCLUSION@#In this study, 2.3% of hematologic malignancy patients had multiple mali-gnancies, lymphoma and MM as the second primary malignancy had poor survival.

Mechanism of Qilongtian Capsules in treatment of acute lung injury based on network pharmacology prediction and experimental validation / 中国中药杂志

This study aimed to explore the mechanism of Qilongtian Capsules in treating acute lung injury(ALI) based on network pharmacology prediction and in vitro experimental validation. Firstly, UPLC-Q-TOF-MS/MS was used to analyze the main chemical components of Qilongtian Capsules, and related databases were used to obtain its action targets and ALI disease targets. STRING database was used to build a protein-protein interaction(PPI) network. Metascape database was used to conduct enrichment analysis of Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG). AutoDock software was used to perform molecular docking verification on the main active components and key targets. Then, the RAW264.7 cells were stimulated with lipopolysaccharide(LPS) for in vitro experiments. Cell viability was measured by MTT and ROS level was measured by DCFH-DA. NO content was measured by Griess assay, and IL-1β, IL-6, and TNF-α mRNA expression was detected by RT-PCR. The predicted targets were preliminarily verified by investigating the effect of Qilongtian Capsules on downstream cytokines. Eighty-four compounds were identified by UPLC-Q-TOF-MS/MS. Through database retrieval, 44 active components with 589 target genes were screened out. There were 560 ALI disease targets, and 65 intersection targets. PPI network topology analysis revealed 10 core targets related to ALI, including STAT3, JUN, VEGFA, CASP3, and MMP9. KEGG enrichment analysis showed that Qilongtian Capsules mainly exerted an anti-ALI effect by regulating cancer pathway, AGE-RAGE, MAPK, and JAK-STAT signaling pathways. The results of molecular docking showed that the main active components in Qilongtian Capsules, including crenulatin, ginsenoside F_1, ginsenoside Rb_1, ginsenoside Rd, ginsenoside Rg_1, ginsenoside Rg_3, notoginsenoside Fe, notoginsenoside G, notoginsenoside R_1, notoginsenoside R_2, and notoginsenoside R_3, had good binding affinities with the corresponding protein targets STAT3, JUN, VEGFA, CASP3, and MMP9. Cellular experiments showed that Qilongtian Capsules at 0.1, 0.25, and 0.5 mg·mL~(-1) reduced the release of NO, while Qilongtian Capsules at 0.25 and 0.5 mg·mL~(-1) reduced ROS production, down-regulated mRNA expression of IL-1β, IL-6, TNF-α, and inhibited the inflammatory cascade. In summary, Qilongtian Capsules may exert therapeutic effects on ALI through multiple components and targets.

Application of two noninvasive scores in predicting the risk of respiratory failure in full-term neonates: a comparative analysis / 中国当代儿科杂志

OBJECTIVES@#To study the value of Silverman-Anderson score versus Downes score in predicting respiratory failure in full-term neonates.@*METHODS@#The convenience sampling method was used to select the full-term neonates with lung diseases who were hospitalized in the neonatal intensive care unit from July 2020 to July 2021. According to the diagnostic criteria for neonatal respiratory failure, they were divided into a respiratory failure group (65 neonates) and a non-respiratory failure group (363 neonates). Silverman-Anderson score and Downes score were used for evaluation. The receiver operating characteristic analysis was used to compare the value of the two noninvasive scores in predicting respiratory failure in full-term neonates.@*RESULTS@#Among the 428 full-term neonates, 65 (15.2%) had respiratory failure. The Silverman-Anderson score had a significantly shorter average time spent on evaluation than the Downes score [(90±8) seconds vs (150±13) seconds; P<0.001]. The respiratory failure group had significantly higher points in both the Silverman-Anderson and Downes scores than the non-respiratory failure group (P<0.001). The Silverman-Anderson score had an AUC of 0.876 for predicting respiratory failure, with a sensitivity of 0.908, a specificity of 0.694, and a Youden index of 0.602 at the optimal cut-off value of 4.50 points. The Downes score had an AUC of 0.918 for predicting respiratory failure, with a sensitivity of 0.723, a specificity of 0.953, and a Youden index of 0.676 at the optimal cut-off value of 6.00 points. The Downes score had significantly higher AUC for predicting respiratory failure than the Silverman-Anderson score (P=0.026).@*CONCLUSIONS@#Both Silverman-Anderson and Downes scores can predict the risk of respiratory failure in full-term neonates. The Silverman-Anderson score requires a shorter time for evaluation, while the Downes score has higher prediction efficiency. It is recommended to use Downes score with higher prediction efficiency in general evaluation, and the Silverman-Anderson score requiring a shorter time for evaluation can be used in emergency.

Historical evolution and research advance in processing adjuvant--vinegar / 中国中药杂志

Processing of Chinese medicinals with vinegar is one of the characteristic processing techniques. Vinegar is vital for the quality of vinegar-processed decoction pieces. However, there have been no specified standards for adjuvants. Through consulting relevant literature and monographs, we comprehensively reviewed the historical evolution of processing with vinegar in records, selection and application of vinegar, and summarized the relevant standards and current status of vinegar as an adjuvant in China. According to the records in literature, vinegar is effective in activating blood, moving qi, dispersing blood stasis, removing toxin, promoting appetite, and nourishing the liver. Traditionally, rice vinegar is chosen in processing. Nowadays, the vinegar made from rice under solid-state fermentation should be chosen. At present, only food standards can be taken for reference for vinegar in the processing. Integrative and specific inspection indicators are lacking, so the standards for adjuvants need to be improved urgently. In addition, the inadequacy in quality control and management is also a major problem to be solved. Through literature research, we reviewed the historical evolution and research advance in vinegar to provide a reference for the standardization and further research of vinegar used in the Chinese medicinal processing.

Assessment of growth pattern of preterm infants up to a corrected age of 24 months / 中国当代儿科杂志

OBJECTIVES@#To assess the growth of preterm infants up to a corrected age of 24 months, and to understand the growth trend and pattern of preterm infants.@*METHODS@#A preterm infant follow-up database was established based on the Internet Plus follow-up system. A total of 3 188 preterm infants who were born from April 2018 to April 2021 were enrolled. Their length, weight, and head circumference were recorded at birth and at the corrected ages of 1, 3, 6, 12, 18, and 24 months. The preterm infants were grouped by perinatal factors. The growth curves of these infants were plotted and compared with the International Fetal and Newborn Growth Consortium for the 21st Century (INTERGROWTH-21st) standard and World Health Organization (WHO) standard.@*RESULTS@#The weight, length, and head circumference curves of each group of preterm infants grouped by various perinatal factors all rose rapidly within the corrected age of 6 months, but the growth rate slowed down after the corrected age of 6 months. Based on the actual age for the groups of preterm infants with different gestational ages (<28 weeks, 28-31@*CONCLUSIONS@#The physical growth rate of preterm infants is faster within the corrected age of 6 months, and the growth rate slows down after the corrected age of 6 months. Preterm infants with a smaller gestational age need longer time to catch up in weight and head circumference. More attention should be paid to the physical growth of extremely preterm infants, extremely low birth weight infants, and small-for-gestational-age infants.

Outcomes of 138 myelodysplastic syndrome patients with HLA-matched sibling donor allogeneic hematopoietic stem cell transplantation / 中华血液学杂志

Objective: To evaluate the outcomes of myelodysplastic syndromes (MDS) patients who received HLA-matched sibling donor allogeneic peripheral blood stem cell transplantation (MSD-PBSCT) . Methods: The clinical data of 138 MDS patients received MSD-PBSCT from Sep. 2005 to Dec. 2017 were retrospectively analyzed, and the overall survival (OS) rate, disease-free survival (DFS) rate, relapse rate (RR) , non-relapse mortality (NRM) rate and the related risk factors were explored. Results: ①After a median follow-up of 1 050 (range 4 to 4 988) days, the 3-year OS and DFS rates were (66.6±4.1) % and (63.3±4.1) %, respectively. The 3-year cumulative incidence of RR and NRM rates were (13.9±0.1) % and (22.2±0.1) %, respectively. ②Univariate analysis showed that patients with grade Ⅲ-Ⅳ acute graft-versus-host disease (aGVHD) or hematopoietic cell transplantation comorbidity index (HCT-CI) ≥2 points or patients in very high-risk group of the Revised International Prognostic Scoring System (IPSS-R) had significantly decreased OS[ (42.9±13.2) %vs (72.9±4.2) %, χ(2)=8.620, P=0.003; (53.3±7.6) %vs (72.6±4.7) %, χ(2)=6.681, P=0.010; (53.8±6.8) %vs (76.6±6.2) %vs (73.3±7.7) %, χ(2)=6.337, P=0.042]. For MDS patients with excess blasts-2 (MDS-EB2) and acute myeloid leukemia patients derived from MDS (MDS-AML) , pre-transplant chemotherapy or hypomethylating agents (HMA) therapy could not improve the OS rate[ (60.4±7.8) %vs (59.2±9.6) %, χ(2)=0.042, P=0.838]. ③Multivariate analysis indicated that the HCT-CI was an independent risk factor for OS and DFS (P=0.012, HR=2.108, 95%CI 1.174-3.785; P=0.008, HR=2.128, 95%CI 1.219-3.712) . Conclusions: HCT-CI was better than the IPSS-R in predicting the outcomes after transplantation. The occurrence of grade Ⅲ-Ⅳ aGVHD is a poor prognostic factor for OS. For patients of MDS-EB2 and MDS-AML, immediate transplantation was recommended instead of receiving pre-transplant chemotherapy or HMA therapy.

Clinical application of midpiece facial nerve dissection in regional parotidectomy / 华西口腔医学杂志

OBJECTIVE@#To propose and evaluate the clinical effect of midpiece facial nerve dissection through transparotid approach in regional parotidectomy.@*METHODS@#A total of 136 patients with benign parotid tumors were categorized into three groups according to the way of facial nerve dissection: anterograde dissection from main trunk (anterograde, n=70), retrograde dissection from distal branches (retrograde, n=34), and midpiece dissection through transparotid approach (middle dissection, n=32). Surgery duration, facial nerve injury, salivary fistula, earlobe sensation, Frey's syndrome, and aesthetic evaluation were compared.@*RESULTS@#The surgery duration in the middle dissection group was significantly shorter than that in the other two groups. The proportion of salivary fistula was higher in the anterograde group (9 cases, 12.9%; P<0.05) compared with that in the other groups. Postoperative facial nerve injury was similar between the middle dissection (1 case, 3.1%) and anterograde groups (3 cases, 4.3%) with lower injury rate compared with the retrograde group (7 cases, 20.6%). The anterograde group had more cases of hypoesthesia of the earlobe (12 cases, 17.1%; P<0.05) than the other two groups. Aesthetic score was higher in the anterograde and middle dissection groups compared with that in the retrograde group (P<0.05).@*CONCLUSIONS@#Midpiece facial nerve dissection is technically feasible and clinically viable in regional parotidectomy.

Bromodomain and extraterminal proteins-a novel class of therapeutic targets in epigenetics / 药学学报

Bromodomain and extraterminal (BET) proteins are a class of proteins that can interpret epigenetic codes and play an important role in regulating gene transcription through identifying and binding acetylated histones or non-histones proteins. The BET inhibitors have emerged with good therapeutic effects in preclinical disease models such as cancer and inflammation. Some of them have entered clinical studies, demonstrating that there is considerable prospect for drug development with BET as a potential therapeutic target. This review briefly describes the structures and functions of the BET proteins, the BET inhibitors in various diseases, as well as molecular mechanisms involved.

Analysis of Hematopoietic Reconstitution in Auto-Peripheral Blood Hematopoietic Stem Cell Transplantation / 中国实验血液学杂志

<p><b>OBJECTIVE</b>To explore the factors which may have influences on hematopoietic reconstitution of the auto-peripheral blood stem cell transplantation(auto-PBHSCT).</p><p><b>METHODS</b>The successful rate, the time of hematopoietic reconstitution and implantation status at 28 days after transplantation of 177 patients received auto-PBSCT were retropectively analyzed, in order to explore the factors which may have influences on hematopoietic reconstitution.</p><p><b>RESULTS</b>The median time of neutrophil recovery was 12 days (8-21 days), implantation rate was 98.9%, all patients' neutrophil were recovered in 28 days. The median time of platelet recovery was 17 days (7-420 days), implantation rate was 95.5%, the cumulative incidence of platelet recovery at day 28 was 80.8%. Univariate analysis showed that the CD34cell number and the use of TPO had effect on neutrophils recovery time; the disease kinds, conditioning regimen and the infused CD34cell number had influence on platelets recovery time. Multivariate analysis showed that the CD34cell number was the independent influencing factor of neutrophils reconstitution time; the disease kinds, the CD34cell number were the independent influencing factors of platelet reconstitution time. Disease kinds and the CD34cell number were the independent influencing factors of hematopoietic reconstitution status of 28 days after transplantation.</p><p><b>CONCLUSION</b>In auto-PBHSCT patients, disease kinds, conditioning regimen, the infused CD34cell number and the use of TPO have been confirmed to be independent influencing factors on hematopoietic reconstitution.</p>

Analysis of clinical features of 56 cases with Terrien's marginal degeneration / 国际眼科杂志(Guoji Yanke Zazhi)

?AIM:To analyze the clinical features of Terrien marginal degeneration ( TMD) .?METHODS:Fifty-six patients(90 eyes) admitted in our hospital from January 2013 to January 2015 were selected as observation group.At the same period, 56 healthy (88 eyes) for corneal examination were as control group to analyze the clinical features of TMD. With immunohistochemistry and enzyme linked immunoassay method ( ELISA), the levels of HLA-DR, HLA-DQ and tumor necrosis factor-α( TNF-α) in blood samples of TMD patients were tested.?RESULTS:The transparent degree of the eye, lipid deposition in TMD patients with early, advanced, swelling and hole-wearing period were significantly different (χ2=10.85,χ2=65.32, P<0.05).Astigmatism in TMD patients with early and advanced, swelling and hole -wearing period were significantly different (P<0.05).The levels of HLA-DR, HLA-DQ and TNF-αin blood samples between the two groups were significantly different ( t=45.326, t=23.564, t=19.86, P<0.05).?CONCLUSION: Terrien's marginal degenerative is an inflammatory disease characterized by increased levels of TNF-α, HLA-DQ, and HLA-DR in peripheral blood, decreased corneal transparency, astigmatism and lipid deposition.This research provides experiment evidence for the mechanism of TMD.
