Research progress on the manifestations and prognosis of neonatal lupus erythematosus in various systems / 中国当代儿科杂志

Neonatal lupus erythematosus (NLE) is caused by the transmission of maternal anti-Ro/SSA antibodies, anti-La/SSB antibodies, and other autoantibodies to the fetus through the placenta. Usually, with the disappearance of autoantibodies in the children's body, abnormal changes in the mucocutaneous, blood system, and digestive system can spontaneously subside, but the damage to various systems caused by autoantibodies may persist for a long time. This article provides a comprehensive review of the manifestations and prognosis of NLE in various systems, including mucocutaneous, blood system, circulatory system, nervous system, digestive system, respiratory system, aiming to provide reference for clinical work.

Progress on study of factors influencing the prognosis and complications of surgery for discoid meniscus injury in children / 中国骨伤

The discoid meniscus is a common congenital meniscal malformation that is prevalent mainly in Asians and often occurs in the lateral discoid meniscus. Patients with asymptomatic discoid meniscus are usually treated by conservative methods such as observation and injury avoidance, while patients with symptoms and tears need to be treated surgically. Arthroscopic saucerization combined with partial meniscectomy and meniscus repair is the most common surgical approach., and early to mid-term reports are good. The prognostic factors are the patient's age at surgery、follow-up time and type of surgery. Some patients experience complications such as prolonged postoperative knee pain, early osteoarthritis, retears and Osteochondritis dissecans. The incidence of prolonged postoperative knee pain was higher and the incidence of Osteochondritis dissecans was the lowest. Retears of the lateral meniscus is the main reason for reoperation.

Analysis of 9 cases of drug induced hypersensitivity syndrome related hemophagocytic lymphohistiocytosis / 中华儿科杂志

Objective: To analyze the clinical features,treatment and prognosis of drug induced hypersensitivity syndrome related hemophagocytic lymphohistiocytosis (DIHS-HLH). Methods: This was a retrospective case study. Clinical characteristics, laboratory results, treatment and prognosis of 9 patients diagnosed with DIHS-HLH in Beijing Children's hospital between January 2020 and December 2022 were summarized. Kaplan-Meier survival analysis was used to calculate the overall survival rate. Results: Among all 9 cases, there were 6 males and 3 females, with the age ranged from 0.8 to 3.1 years. All patients had fever, rash, hepatomegaly and multiple lymph node enlargement. Other manifestations included splenomegaly (4 cases), pulmonary imaging abnormalities (6 cases), central nervous system symptoms (3 cases), and watery diarrhea (3 cases). Most patients showed high levels of soluble-CD25 (8 cases), hepatic dysfunction (7 cases) and hyperferritinemia (7 cases). Other laboratory abnormalities included hemophagocytosis in bone marrow (5 cases), hypofibrinogenemia (3 cases) and hypertriglyceridemia (2 cases). Ascending levels of interleukin (IL) 5, IL-8 and interferon-γ (IFN-γ) were detected in more than 6 patients. All patients received high dose intravenous immunoglobulin, corticosteroid and ruxolitinib, among which 4 patients were also treated with high dose methylprednisolone, 2 patients with etoposide and 2 patients with cyclosporin A. After following up for 0.2-38.6 months, 7 patients survived, and the 1-year overall survival rate was (78±14)%. Two patients who had no response to high dose immunoglobulin, methylprednisolone 2 mg/(kg·d) and ruxolitinib died. Watery diarrhea, increased levels of IL-5 and IL-8 and decreased IgM were more frequently in patients who did not survive. Conclusions: For children with fever, rash and a suspicious medication history, when complicated with hepatomegaly, impaired liver function and high levels of IL-5 and IL-8, DIHS-HLH should be considered. Once diagnosed with DIHS-HLH, suspicious drugs should be stopped immediately, and high dose intravenous immunoglobulin, corticosteroid and ruxolitinib could be used to control disease.

In order to explore the medical and social problems related to postoperative lymphedema in breast cancer patients, improve the compliance of rehabilitation treatment and help patients return to society. The self-designed questionnaire was used to investigate 76 patients who met the criteria of lymphedema after breast cancer and refused or failed to adhere to rehabilitation threapy. According to the relevant measurement scale theory and method, the computer-aided software was used to analyze the data to find out the problem and analyze the cause. The prominent problems of poor compliance in patients with breast cancer after operation were successively: subjective factors, objective factors, family social and ethical factors, multidisciplinary factors, hospital management and policy issues. For the above ethical problems, we should adopt positive coping strategies to increase the compliance of patients and improve their quality of life.

The Uptake and Distribution Evidence of Nano- and Microplastics in vivo after a Single High Dose of Oral Exposure / 生物医学与环境科学（英文）

OBJECTIVE@#Tissue uptake and distribution of nano-/microplastics was studied at a single high dose by gavage in vivo.@*METHODS@#Fluorescent microspheres (100 nm, 3 μm, and 10 μm) were given once at a dose of 200 mg/(kg∙body weight). The fluorescence intensity (FI) in observed organs was measured using the IVIS Spectrum at 0.5, 1, 2, and 4 h after administration. Histopathology was performed to corroborate these findings.@*RESULTS@#In the 100 nm group, the FI of the stomach and small intestine were highest at 0.5 h, and the FI of the large intestine, excrement, lung, kidney, liver, and skeletal muscles were highest at 4 h compared with the control group ( P < 0.05). In the 3 μm group, the FI only increased in the lung at 2 h ( P < 0.05). In the 10 μm group, the FI increased in the large intestine and excrement at 2 h, and in the kidney at 4 h ( P < 0.05). The presence of nano-/microplastics in tissues was further verified by histopathology. The peak time of nanoplastic absorption in blood was confirmed.@*CONCLUSION@#Nanoplastics translocated rapidly to observed organs/tissues through blood circulation; however, only small amounts of MPs could penetrate the organs.

Artesunate Combined with Other Medications and Action Mechanism： A Review / 中国实验方剂学杂志

A sesquiterpene natural substance called artemisinin was discovered in Artemisia annua. One of its derivatives， artesunate （ART）， has the properties of economy， immediate effect， low toxicity， and good tolerance. Since it has a quick and powerful killing effect on plasmodium in the erythrocyte phase and can quickly handle clinical seizure and symptoms， it is currently mostly utilized to treat cerebral malaria and other severe instances of malaria. In addition， it has antitumor， antivirus， anti-hepatic fibrosis， anti-inflammatory， antibacterial， hepatocyte protection， immunological modulation， and other pharmacological properties and can inhibit cell proliferation， induce cell apoptosis， and reduce the incidence of sepsis. In many countries， artemisinin-based combination therapies （ACTs）， such as artemether-benflumetol， artesunate-amodiaquine， and artemether-lumefantrine， are the first-line treatments for malaria. Recent research on artesunate by Chinese and international scholars has revealed that compared with monotherapy， artesunate combination therapy offers more benefits in terms of improving pharmacological effects， shortening the duration of medicine， and minimizing adverse effects. Through systematic retrieval of Web of Science Core Collection and integration through CiteSpace （6.2.1） software， this article reviewed the mechanism of artesunate combined with other medications with regard to antimalarial， antitumor， antibacterial， and antiviral features in the previous five years， so as to provide some theoretical basis for rational development and utilization of ART and new drug research and development.

The 501st case: elevated blood glucose, chronic pancreatitis, and post- pancreatoduodenectomy malnutrition / 中华内科杂志

A 50-year-old man with a 15-year history of elevated blood glucose and an approximately 2-year history of diarrhea was admitted to the Peking Union Medical College Hospital. The initial diagnosis was type 2 diabetes. After repeated pancreatitis and pancreatoduodenectomy, severe pancreatic endocrine and exocrine dysfunction including alternating high and low blood glucose and fat diarrhea occurred. Tests for type 1 diabetes-related antibodies were all negative, C-peptide levels were substantially reduced, fat-soluble vitamin levels were reduced, and there was no obvious insulin resistance. Therefore, a diagnosis of pancreatic diabetes was clear. The patient was given small doses of insulin and supplementary pancreatin and micronutrients. Diarrhea was relieved and blood glucose was controlled. The purpose of this article is to raise clinicians' awareness of the possibility of pancreatic diabetes after pancreatitis or pancreatic surgery. Timely intervention and monitoring may reduce the occurrence of complications.

Performance of screening of contacts of COVID-19 cases in same flight / 中华流行病学杂志

Objective: To understand the performance of 2019-nCoV nucleic acid detection in screening of contacts of COVID-19 cases in same flights and provide evidence for the effective screening of persons at high risk for the infection in domestic flights. Methods: The information of passengers who took same domestic flights with COVID-19 cases in China from April 1, 2020 to April 30, 2022 were retrospectively collected,and χ2 test was used to analyze positive nucleic acid detection rates in the passengers in different times before the onsets of the index cases, in different seat rows and in epidemic periods of different 2019-nCoV variants. Results: During the study period, a total of 433 index cases were identified among 23 548 passengers in 370 flights. Subsequently, 72 positive cases of 2019-nCoV nucleic acid were detected in the passengers, in whom 57 were accompanying persons of the index cases. Further analysis of the another 15 passengers who tested positive for the nucleic acid showed that 86.67% of them had onsets or positive detections within 3 days after the diagnosis of the index cases, and the boarding times were all within 4 days before the onsets of the index cases. The positive detection rate in the passengers who seated in first three rows before and after the index cases was 0.15% (95%CI: 0.08%-0.27%), significantly higher than in the passengers in other rows (0.04%, 95%CI: 0.02%-0.10%, P=0.007),and there was no significant difference in the positive detection rate among the passengers in each of the 3 rows before and after the index cases (P=0.577). No significant differences were found in the positive detection rate in the passengers, except the accompanying persons, among the epidemics caused by different 2019-nCoV variants (P=0.565). During the Omicron epidemic period, all the positive detections in the passengers, except the accompanying persons, were within 3 days before the onset of the index cases. Conclusions: The screening test of 2019-nCoV nucleic acid can be conducted in the passengers took the same flights within 4 days before the onsets of the index cases on board. Passengers who seated within 3 rows from the index cases can considered as the close contacts at high risk for 2019-nCoV, for whom screening should be conducted first and special managements are needed. The passengers in other rows can be classified as general risk persons for screening and management.

Objective: To investigate the feasibility and value of histogram analysis based on two-dimensional gray-scale ultrasonography in the differential diagnosis of medullary thyroid carcinoma (MTC) and thyroid adenoma (TA). Methods: The preoperative ultrasound images of 86 newly diagnosed MTC patients and 100 TA patients treated in the Cancer Hospital of Chinese Academy of Medical Sciences from January 2015 to October 2021 were collected. Histograms were performed based on the regions of interest (ROIs) delineated manually by two radiologists, thereafter, mean, variance, skewness, kurtosis, percentiles (1st, 10th, 50th, 90th, 99th) were generated. The histogram parameters between the MTC group and the TA group were compared, and the independent predictors were screened by multivariate logistic regression analysis. Receiver operating characteristic (ROC) analysis was used to compare the individual diagnostic efficacy and joint diagnostic efficacy of independent predictors. Results: Multivariate regression analysis showed that mean, skewness, kurtosis and 50th percentile were independent factors. The skewness and kurtosis in the MTC group were significantly higher than those in the TA group, and the mean and 50th percentile were significantly lower than those in the TA group. The area under the individual ROC curve of mean, skewness, kurtosis and 50th percentile is 0.654-0.778. The area under the combined ROC curve is 0.826. Conclusion: Histogram analysis based on two-dimensional gray-scale ultrasonography is a promising tool to distinguish MTC from TA, in which the joint diagnosis value of mean, skewness, kurtosis and 50th percentile is the highest.

ZHANG Lei's Experience in Treating Scleroderma from “Extraordinary Pathogens Entering Collaterals” / 中医杂志

This paper summarized professor ZHANG Lei′s experience in treating scleroderma from “extraordinary pathogens entering collaterals”. The basic pathogenesis of scleroderma is “extraordinary pathogens entering the collaterals”， and extraordinary pathogens can be divided into external and internal categories. External extraordinary pathogens are mostly exogenous wind， cold and damp pathogens， and the pathogenesis is wind， cold and damp invading skin stria and retaining collaterals. Most of the endogenous extraordinary pathogens are turbid phlegm and blood stasis， and the pathogenesis is endogenous phlegm and stasis leaving the channels and overflowing the collaterals， and blocking the collaterals. Blocked by extraordinary pathogens for a long time， the long illness will lead to deficiency and develop into a syndrome of collaterals excess and channels deficiency. Therefore， professor ZHANG creats Tengluo Beverage （藤络饮） as the basic formula to unblock collaterals and dispel pathogens， and recommends to add or subtract it according to the different syndrome and pathogenic characteristics of the edema stage， sclerosis stage， and atrophy stage. In the edema stage， it is advised to expel wind， remove dampness and unblock the collaterals， while in the sclerosis stage， the method of dissolving phlegm， expelling stasis and unblocking collaterals should be used； in the atrophic stage， it is suggested to differentiate the deficiency of qi， blood， yin and yang， and eliminate extraordinary pathogens on the basis of reinforcing healthy qi .

In the control group, the systolic blood pressure of children with TT genotype increased more than those with GT and GG genotype( β=-2.86, 95%CI=-5.63--0.83, P <0.05). There was an interaction between rs 12145833 polymorphism of SDCCAG 8 gene and intervention on systolic blood pressure, diastolic blood pressure and body fat percentage in children( P <0.05).@*Conclusion@#Children with TT genotype of rs 12145833 in the SDCCAG 8 gene are more sensitive to obesity intervention than those with GG and GT genotypes, especially in the improvement of systolic blood pressure, diastolic blood pressure and body fat percentage. Further trials to study the role of rs 12145833 polymorphism of SDCCAG 8 gene in the intervention of childhood obesity among different ethnic populations are needed.

Alterations of β-γ coupling of scalp electroencephalography during epilepsy / 生物医学工程学杂志

Uncovering the alterations of neural interactions within the brain during epilepsy is important for the clinical diagnosis and treatment. Previous studies have shown that the phase-amplitude coupling (PAC) can be used as a potential biomarker for locating epileptic zones and characterizing the transition of epileptic phases. However, in contrast to the θ-γ coupling widely investigated in epilepsy, few studies have paid attention to the β-γ coupling, as well as its potential applications. In the current study, we use the modulation index (MI) to calculate the scalp electroencephalography (EEG)-based β-γ coupling and investigate the corresponding changes during different epileptic phases. The results show that the β-γ coupling of each brain region changes with the evolution of epilepsy, and in several brain regions, the β-γ coupling decreases during the ictal period but increases in the post-ictal period, where the differences are statistically significant. Moreover, the alterations of β-γ coupling between different brain regions can also be observed, and the strength of β-γ coupling increases in the post-ictal period, where the differences are also significant. Taken together, these findings not only contribute to understanding neural interactions within the brain during the evolution of epilepsy, but also provide a new insight into the clinical treatment.

Therapeutic effect and mechanism of non-polysaccharide fraction of Bletillae Rhizoma in treatment of gastric ulcer based on network pharmacology and animal experiment / 中国中药杂志

The present study aimed to explore the therapeutic effect and mechanism of non-polysaccharide fraction of Bletillae Rhizoma in the treatment of gastric ulcer by network pharmacology and animal experiments. UPLC-Q-TOF-MS/MS was employed to chara-cterize the chemical components of non-polysaccharide fraction of Bletillae Rhizoma, and the common targets of Bletillae Rhizoma and gastric ulcer were screened out by network pharmacology. The "drug-component-target-disease" network was constructed. Protein-protein interaction(PPI) network was established by STRING. Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses were performed based on Matescape database to predict the therapeutic effect and mechanism of Bletillae Rhizoma. Finally, the gastric ulcer model was induced in mice by alcohol to verify the therapeutic effect and mechanism of non-polysaccharide fraction of Bletillae Rhizoma on gastric ulcer. Forty-seven chemical components were identified from non-polysaccharide fraction of Bletillae Rhizoma, among which gymnoside Ⅰ, gymnoside Ⅱ, militarine, bletilloside A, and shancigusin I might be the main active components of non-polysaccharide fraction of Bletillae Rhizoma against gastric ulcer. PPI network analysis revealed core targets such as albumin(ALB), serine/threonine kinase 1(AKT1), tumor necrosis factor(TNF), and epidermal growth factor receptor(EGFR). The KEGG enrichment analysis showed that non-polysaccharide fraction of Bletillae Rhizoma mainly exerted the therapeutic effect by regulating the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(AKT) signaling pathway, mitogen-activated protein kinase(MAPK) signaling pathway, and Ras signaling pathway. The results of animal experiments showed that non-polysaccharide fraction of Bletillae Rhizoma could significantly improve alcohol-induced ulceration in mice to increase ulcer inhibition rate, decrease the levels of TNF-α, interleukin(IL)-1β, IL-6, vasoactive intestinal peptide(VIP), and thromboxane B2(TXB2), elevated the le-vels of IL-10, prostaglandin E2(PGE2), epidermal growth factor(EGF), and vascular endothelial growth factor(VEGF), down-re-gulate the protein levels of PI3K and AKT, and up-regulate the protein levels of p-PI3K and p-AKT. This study indicates that Bletillae Rhizoma may play a role in the treatment of gastric ulcer through multiple components, targets, and pathways and verifies partial prediction results of network pharmacology. The findings of this study provide a scientific and experimental basis for clinical application.

Evolution and development of potent monobactam sulfonate candidate IMBZ18g as a dual inhibitor against MDR Gram-negative bacteria producing ESBLs

A series of new monobactam sulfonates is continuously synthesized and evaluated for their antimicrobial efficacies against Gram-negative bacteria. Compound 33a (IMBZ18G) is highly effective in vitro and in vivo against clinically intractable multi-drug-resistant (MDR) Gram-negative strains, with a highly druglike nature. The checkerboard assay reveals its significant synergistic effect with β-lactamase inhibitor avibactam, and the MIC values against MDR enterobacteria were reduced up to 4-512 folds. X-ray co-crystal and chemoproteomic assays indicate that the anti-MDR bacteria effect of 33a results from the dual inhibition of the common PBP3 and some class A and C β-lactamases. Accordingly, preclinical studies of 33a alone and 33a‒avibactam combination as potential innovative candidates are actively going on, in the treatment of β-lactamase-producing MDR Gram-negative bacterial infections.

There was no in-hospital death and perioperative cardiovascular events. Perioperative cerebral infarction occurred in 3 patients. 1 patients was reoperated for bleeding. Intra-aortic balloon pump (IABP) assistance was used in 21 patients. Poor wound healing occurred in 2 cases and healed well after debridement. Follow-up of 2 to 20 months after discharge showed no internal mammary artery occlusion and 4 radial artery occlusions; no major adverse cardiovascular and cerebrovascular event (MACCE) occurred, and the survival rate was 100%. There was no significant difference in the above perioperative complications and follow-up endpoints between the two age groups.@*CONCLUSIONS@#By adjusting the order of bypass anastomosis and optimizing the preoperative evaluation method, radial artery combined with internal mammary artery can obtain better outcome early in TAR, and can be safely and reliably applied to elderly patients.

Research progress on long-term developmental outcomes of offspring of pregnant women with systemic lupus erythematosus / 中国当代儿科杂志

Systemic lupus erythematosus (SLE) is an autoimmune connective tissue disease that affects multiple organs and systems. It is more common in women of childbearing age. Compared with the general population, pregnant women with SLE are at a significantly increased risk of adverse perinatal outcomes such as preterm birth and intrauterine growth restriction. In addition, the offspring of SLE patients may also be adversely affected by in utero exposure to maternal autoantibodies, cytokines, and drugs. This article summarizes the long-term developmental outcomes of offspring of pregnant women with SLE in terms of the blood system, circulatory system, nervous system, and immune system.
