Internal experiences of financial toxicity in cancer patients: a Meta-synthesis / 中国实用护理杂志

Objective:This study aims to investigate the inner experiences of cancer patients when confronting financial toxicity through a Meta-analytical approach. The goal is to provide evidence-based insights and theoretical references for clinical healthcare professionals to fully understand the feelings and experiences associated with financial toxicity in cancer patients, thereby laying a foundation for targeted interventional measures.Methods:A computerized search was conducted across databases including CINAHL, PubMed, PsycINFO, Embase, Scopus, Web of Science, CNKI, WanFang, VIP, Sinomed and other databases, collecting qualitative studies related to the inner experience of financial toxicity among cancer patients, up until April 12, 2023. Quality appraisal of the included literature was carried out according to JBI′s standards for qualitative research, and results were synthesized using Meta-aggregation methods.Results:Twenty-three studies were included, from which 82 specific outcomes were extracted. These were categorized into 11 new thematic groups and ultimately synthesized into four integrated findings: the impact of objective costs, subjective burden, and unreasonable expectations; diverse cognitive attitudes and management coping strategies; multiple pressures and challenges on patients and their families; and the articulation of needs and perceptions of beneficial growth.Conclusions:Healthcare professionals should pay attention to the financial toxicity issues that patients face at the initial stage of cancer diagnosis. Timely communication about economic issues between patients and healthcare providers is essential to help patients have a preliminary understanding of the impending financial toxicity at the onset of the disease. A comprehensive intervention that emphasizes different aspects of objective and subjective financial toxicity, coupled with multi-dimensional mitigation strategies, can promote active coping in patients, enhance familial emotional and financial support to overcome challenges together, and prioritize patients′ needs and expectations to guide them towards reinforcing positive experiences and minimizing the impact of financial toxicity.

Predictors of a forgotten joint after medial open wedge high tibial osteotomy / 中国组织工程研究

BACKGROUND:Medial open wedge high tibial osteotomy is an effective procedure for preserving the knee joint in patients with medial compartmental osteoarthritis.Previous studies have demonstrated that the forgotten joint score provides a lower ceiling effect and consistency of medial open wedge high tibial osteotomy outcomes compared to traditional assessment tools. OBJECTIVE:To identify predictive factors associated with the occurrence of a forgotten joint after medial open wedge high tibial osteotomy. METHODS:117 patients with medial open wedge high tibial osteotomy who were treated at First Affiliated Hospital of Guangzhou University of Chinese Medicine were selected,including 35 males and 82 females,with an average age of 61 years.They were followed up for at least 2 years.Patients were divided into a forgotten joint group(n=28)and a non-forgotten joint group(n=89)by evaluating whether they achieved forgotten joint after surgery.Univariate and multivariate logistic regression analyses were performed with preoperative patient characteristics and surgery-related factors as potential predictors. RESULTS AND CONCLUSION:(1)There were significant differences in the proximal medial tibial angle between the two groups before surgery(P<0.05).There were significant differences in the forgotten joint score,Knee Injury and Osteoarthritis Outcome Score,knee society knee score,function score,and patients joint perception between the two groups after surgery(P<0.05).There was a significant difference between the hip-knee-ankle angle and the medial proximal tibial angle after operation(P<0.05).(2)Univariate Logistic regression analysis showed that the medial proximal tibial angle had a significant influence on the forgotten joint before operation[OR=0.755,95%CI(0.635-0.897),P<0.001].There were significant effects on the forgotten joint of hip-knee-ankle angle and medial proximal tibial angle[OR=1.546,95%CI(1.242-1.924),P<0.001;OR=0.815,95%CI(0.713-0.931),P=0.003].(3)Multivariate logistic regression analysis showed that preoperative K-L grade 1 was a favorable factor for obtaining forgotten joints.Preoperative medial proximal tibial angle and postoperative hip-knee-ankle angle were independent predictors of forgetting joints,and they had a curvilinear relationship with the probability of achieving forgetting joints.When preoperative medial proximal tibial angle increased by 1°,the probability of achieving a forgotten joint decreased by 27.7%[OR=0.723,95%CI(0.593-0.882),P<0.001].Conversely,when postoperative hip-knee-ankle angle increased by 1°,the probability of achieving a forgotten joint increased by 46.4%[OR=1.464,95%CI(1.153-1.860),P=0.002].(4)The results showed that patients with preoperative knee osteoarthritis K-L grade 1,small medial proximal tibial angle(<85.5°),and large postoperative hip-knee-ankle angle(>176.0°)were predictors of forgotten joint.

Quantitative evaluation of lumbar facet arthritis-induced cartilage injury by MR T2* mapping / 中国组织工程研究

BACKGROUND:Lumbar facet arthritis is one of the main causes of low back pain.At present,MRI is mainly used for preliminary diagnosis,and there is still a certain probability of missed diagnosis and misdiagnosis.Therefore,MR T2* mapping imaging technology is expected to become an important means of quantitative detection of cartilage damage in lumbar facet arthritis. OBJECTIVE:To investigate the application value of MR T2* mapping imaging technique in quantitative analysis of cartilage damage and degeneration of lumbar facet joint. METHODS:A total of 110 outpatient or inpatient patients with low back pain in Fourth Affiliated Hospital of Nanjing Medical University from April 2020 to March 2022 were collected and set as case group.At the same time,80 asymptomatic volunteers were recruited as the control group.T2* mapping transectal images and T2WI images were obtained by 3.0T MR Scanning for the facet joints of all included subjects L1-S1.Weishaupt grading and T2* value measurement were performed for all facet joint cartilage,and the data were collected for parallel statistical analysis.The comparison of T2* values of facet joint cartilage between different articular Weishaupt grades was performed by one-way analysis of variance. RESULTS AND CONCLUSION:(1)Statistical analysis found that the T2* value of lumbar facet joint cartilage in the case group(17.6±1.5)ms was significantly lower than that in the control group(21.4±1.3)ms(P<0.05).(2)In the case group,with the hierarchical increase of lumbar facet joint Weishaupt,the T2*value of facet joint cartilage also showed a gradual decreasing trend,and the difference was statistically significant(P<0.05).(3)It is concluded that T2*mapping can better display the early pathological changes of lumbar facet joint cartilage injury,and T2* value of lumbar facet joint cartilage can quantitatively evaluate the degree of lumbar facet joint cartilage injury.T2* mapping imaging technique can provide a good theoretical basis for the imaging diagnosis of the early cartilage injury induced by lumbar facet arthritis and has important clinical application value.

The consistency study of quantitative coronary flow fraction and cardiac magnetic resonance imaging in evaluating myocardial ischemia in patients with coronary heart disease / 中国医师杂志

Objective:To evaluate the correlation and consistency between quantitative coronary flow fraction (QFR) and cardiac magnetic resonance imaging (CMR) in assessing myocardial ischemia in patients with coronary heart disease (CAD).Methods:A retrospective analysis was conducted on the data of coronary heart disease patients who underwent load CMR examination and coronary angiography at the Beijing Anzhen Hospital, Capital Medical University from August 2017 to March 2022. CMR examination includes cardiac cine, load/rest myocardial perfusion imaging, and delayed enhancement sequence. According to the results of CMR examination, the patient′s left ventricular myocardial segments were divided into normal segment group and abnormal segment group (further divided into ischemic segment group and infarcted segment group). On the basis of coronary angiography, an artificial intelligence based platform (AngioPlus system) was applied to calculate the preoperative coronary artery QFR value of patients undergoing percutaneous coronary intervention treatment. Kappa test was used to evaluate the consistency of QFR and CMR in diagnosing abnormal myocardium; Mann Whitney U test was used to compare the differences in QFR between groups; The receiver operating characteristic (ROC) curve was used to evaluate the efficacy of QFR in diagnosing abnormal myocardium; Spearman correlation analysis was used to clarify the relationship between myocardial infarction area and QFR value of the supplying coronary artery in patients.Results:Among the 70 CAD patients enrolled, there were 60 males and 10 females, aged (54.1±11.1)years. At the vascular level, the consistency between QFR and CMR in diagnosing myocardial injury (including ischemia and infarction) is moderate (Kappa value=0.514). The sensitivity and specificity of detecting abnormal myocardial segments in CAD patients were 57% and 91%, respectively. The area under the curve (AUC) value of QFR predicting abnormal myocardium in CAD patients was 0.769, and the optimal cutoff value was QFR=0.865. At this time, the sensitivity and specificity of QFR predicting myocardial injury in CAD patients were 67.2% and 84.3%, respectively. The difference in vascular QFR between the normal segment group, ischemic segment group, and infarcted segment group was statistically significant ( P<0.001), with the infarcted segment group having significantly lower QFR values than the other two groups (all P<0.01). The range of myocardial infarction was negatively correlated with the QFR value of the supplying coronary artery ( r=-0.45, P<0.001). At the patient level, the consistency between QFR and CMR in diagnosing myocardial injury (including ischemia and infarction) was moderate (Kappa value=0.445), with a sensitivity of 74% and a specificity of 81% for diagnosing myocardial injury in CAD patients. Conclusions:Compared with CMR, QFR has better specificity in detecting myocardial injury in CAD patients. The QFR value of the infarcted segment group is significantly lower than that of the ischemic group and the normal group. The area of myocardial infarction is negatively correlated with the QFR value of the supplying coronary artery.

Objective Based on the process theory of stress effect,the structural equation model of the influencing factors of self-regulatory fatigue in maintenance hemodialysis patients is constructed,which provides theoretical bases and references for the formulation of intervention programs to relieve self-regulatory fatigue in patients.Method A total of 420 maintenance hemodialysis patients were surveyed using General Information Questionnaire,Self-Regulatory Fatigue Scale,Dialysis Symptom Index,Life Orientation Test-Revised,Perceived Social Support Scale,Brief Illness Perception Questionnaire and Medical Coping Styles Questionnaire.Results Total score of self-regulatory fatigue in maintenance hemodialysis patients was(49.52±10.93),and self-regulatory fatigue showed significant positive correlation with symptom distress,the illness perception,avoidance coping style,yieldly coping(r=0.476,0.428,0.303,0.611,all P＜0.01);self-regulatory fatigue showed significant negative correlation with perceived social support and dispositional optimism(r=-0.410,-0.652,all P＜0.01);it showed no significant correlation with facing coping(r=-0.032,P＞0.05).The Bootstrap analysis revealed that the mediation effect of yielding coping,dispositional optimism,perceived social support,and illness perception between symptom distress and self-regulatory fatigue was significant(95％CI:0.027～0.203).The overall effect of symptom distress on self-regulatory fatigue was(P＜0.001,95％CI:0.576～0.751);the direct effect was(P＜0.001,95％CI:0.170～0.357);the indirect effect was(P＜0.001,95％CI:0.332～0.485);the mediation effect accounted for 61.1％of the total effect value.Conclusion Maintenance hemodialysis patients have a high degree of self-regulatory fatigue,which needs to be further improved.Medical staff should timely identify and evaluate the symptom distress of patients,focus on guiding patients to adjust optimistic disease,provide patients with psychological guidance and stress coping strategies,reduce the negative coping behavior tendency,guide the patients correctly perceive support and care in social relations,help patients set up the correct disease cognition,thus reducing the patient's self-regulatory fatigue.

Icariin Regulates Glucocorticoid-induced Autophagy of Bone Microvascular Endothelial Cells Through PI3K/Akt/mTOR Pathway / 中国实验方剂学杂志

ObjectiveTo investigate the impact of icariin （ICA） on autophagy in glucocorticoid-induced bone microvascular endothelial cells （BMECs） mediated by the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR） signaling pathway. MethodBMECs were isolated and cultured from femoral heads obtained during total hip arthroplasty and identified using immunofluorescence staining. The experimental cells were divided into four groups： A control group， a glucocorticoid group （100 mg·L-1 hydrocortisone）， an ICA group （100 mg·L-1 hydrocortisone+6.7×10-3 mg·L-1 ICA）， and a Rapamycin group （100 mg·L-1 hydrocortisone+6.7×10-3 mg·L-1 ICA+1 mg·L-1 rapamycin）. Autophagy in BMECs was induced using 100 mg·L-1 hydrocortisone. LC3 fluorescence staining was used to observe the peak of autophagy at different time points. Western blot analysis was employed to analyze the expression of autophagy-related proteins and PI3K/Akt/mTOR pathway proteins in each group. Electron microscopy was used to observe autophagosomes and autolysosomes in the cells. ResultHydrocortisone at 100 mg·L-1 induced autophagy in BMECs， reaching a peak at around 5 hours， which then declined with further intervention. Compared to the control group， the glucocorticoid group showed cell membrane damage， disordered organelle arrangement， and a large number of autophagosomes and autolysosomes. Compared to the glucocorticoid group， the ICA group had more intact cell membranes， sparser organelle arrangement， and fewer autophagosomes and autolysosomes. Compared to the ICA group， the Rapamycin group showed cell membrane damage， disordered organelle arrangement， and more autophagosomes and autolysosomes. Compared to the control group， the glucocorticoid group had significantly increased expression of light chain 3B （LC3B）， Atg4B， and p62 （P<0.01）. Compared to the glucocorticoid group， the ICA group showed significantly decreased expression of LC3B， Atg4B， p62， and Beclin-1 （P<0.01）. Compared to the ICA group， the Rapamycin group had significantly increased expression of Atg4B and p62 （P<0.01）. Compared to the control group， the glucocorticoid group had significantly decreased expression of p-PI3K/PI3K， p-Akt/Akt， and p-mTOR/mTOR （P<0.01）. Compared to the glucocorticoid group， the ICA group showed significantly increased expression of p-PI3K/PI3K， p-Akt/Akt， and p-mTOR/mTOR （P<0.01）. Compared to the ICA group， the Rapamycin group had significantly decreased expression of p-PI3K/PI3K， p-Akt/Akt， and p-mTOR/mTOR （P<0.01）. Ubiquitination levels were significantly decreased in the glucocorticoid group compared to the control group （P<0.01）. Compared to the glucocorticoid group， ubiquitination levels were significantly increased in the ICA group （P<0.01）， and significantly decreased in the Rapamycin group compared to the ICA group （P<0.01）. ConclusionThe glucocorticoid-induced autophagy in BMECs is time-dependent. ICA inhibits glucocorticoid-induced autophagy in BMECs， and this effect may be related to the regulation of the PI3K/Akt/mTOR pathway.

MethodThe patients with sequelae of pelvic inflammatory disease （syndrome of combined dampness，heat，and stasis） treated from May 2022 to August 2023 were included in this study and randomized into two groups （79 cases）. The control group was treated with conventional Western medicine，and the observation group was treated with Qingre Huashi Sanjie enema prescription on the basis of the therapy in the control group. Both groups were treated for 12 weeks. The serum levels of monocyte chemoattractant protein-1 （MCP-1），transforming growth factor-β1 （TGF-β1），and interleukin-6 （IL-6） were measured by enzyme linked immunoserbent assay （ELISA） before and after treatment in both groups. The erythrocyte sedimentation rate （ESR） and fibrinogen （FIB） were measured by an automatic blood rheology analyzer before and after treatment in both groups. The serum levels of CD4+，CD4+/CD8+ before and after treatment in both groups were measured by flow cytometry. The traditional Chinese medicine （TCM） symptom score and the 36-item short form survey （SF-36） score were assessed before and after treatment. The uterine artery resistance index （RI），uterine artery pulsatility index （PI），and uterine artery peak systolic velocity （PSV） were measured by Doppler before and after treatment. The clinical efficacy and the occurrence of adverse reactions were compared between the two groups. ResultAfter treatment，the levels of MCP-1，TGF-β1，IL-6，ESR，and FIB decreased in both groups （P<0.01），and the decreases were larger in the observation group than in the control group （P<0.05，P<0.01）. After treatment，the serum levels of CD4+ and CD4+/CD8+ elevated in both groups （P<0.01） and the observation group had higher levels of CD4+ and CD4+/CD8+ than the control group （P<0.05，P<0.01）. The treatment in both groups decreased the TCM symptom score and TCM sign score and increased the SF-36 score （P<0.01），and the changes were more significant in the observation group than in the control group （P<0.05，P<0.01）. In addition，the treatment lowered RI and PI and elevated PSV （P<0.01），and the changes in these indicators were more significant in the observation group than in the control group （P<0.01）. The total response rate in the observation group was 93.67% （74/79），which was higher than that （79.75%，63/79） in the control group （χ2=6.645，P<0.05）. There was no significant difference in the occurrence of adverse reactions between the two groups. ConclusionFor the patients with sequelae of pelvic inflammatory disease （syndrome of combined dampness，heat，and stasis），Qingre Huashi Sanjie enema prescription can reduce inflammation，attenuate hypercoagulability，improve hemodynamics，and regulate the immune function，demonstrating a definite therapeutic effect.

Systematic review and Meta-analysis of efficacy and safety of Tangmaikang Granules in treatment of diabetic peripheral neuropathy / 中国中药杂志

This study aimed to explore the efficacy and safety of Tangmaikang Granules in the treatment of diabetic peripheral neuropathy(DPN). PubMed, Cochrane Library, EMbase, SinoMed, CNKI, Wanfang and VIP were retrieved for randomized controlled trial(RCT) of Tangmaikang Granules in the treatment of DPN. Cochrane handbook 5.3 was used to evaluate the quality of the inclu-ded studies, and RevMan 5.4.1 and Stata 15.1 were employed to analyze data and test heterogeneity. GRADEpro was used to assess the quality of each outcome index. Clinical effective rate was the major outcome index, while the improvement in numbness of hands and feet, pain of extremities, sluggishness or regression of sensation, sensory conduction velocity(SCV) and motor conduction velocity(MCV) of median nerve and peroneal nerve, fasting blood glucose(FBG), 2 h postprandial blood glucose(2hPBG), and glycated hemoglobin(HbA1c) and incidence of adverse reactions were considered as the minor outcome indexes. A total of 19 RCTs with 1 602 patients were eventually included. The Meta-analysis showed that the improvements in clinical effective rate(RR=1.45, 95%CI[1.32, 1.61], P<0.000 01), pain of extremities(RR=1.70, 95%CI[1.27, 2.27], P=0.000 3), MCV of peroneal nerve(MD=4.08, 95%CI[3.29, 4.86], P<0.000 01) and HbA1c(SMD=-1.23, 95%CI[-1.80,-0.66], P<0.000 1) of Tangmaikang Granules alone or in combination in the experimental group were better than those in the control group. Compared with the conditions in the control group, numbness of hands and feet(RR=1.42, 95%CI[1.12, 1.80], P=0.003), sluggishness or regression of sensation(RR=1.41, 95%CI[1.05, 1.91], P=0.02), SCV of median nerve(MD=4.59, 95%CI[0.92, 8.27], P=0.01), SCV of peroneal nerve(MD=4.68, 95%CI[3.76, 5.60], P<0.000 01) and MCV of median nerve(MD=5.58, 95%CI[4.05, 7.11], P<0.000 01) of Tangmaikang Granules in combination in the experimental group were improved by subgroup analysis. The levels of FBG(MD=-0.57, 95%CI[-1.27, 0.12], P=0.11) and 2hPBG(MD=-0.69, 95%CI[-1.70, 0.33], P=0.18) in the experimental group were similar to those in the control group after treatment with Tangmaikang Granules alone or in combination. There was no difference in the safety(RR=1.28, 95%CI[0.58, 2.82], P=0.54) of Tangmaikang Granules in the treatment of DPN between the experimental group and the control group. Tangmaikang Granules could significantly increase clinical effective rate and nerve conduction velocity as well as improve symptoms of peripheral nerve and blood glucose level, and no serious adverse reactions were identified yet. Further validation was needed in future in large-sample, multicenter, high-quality RCTs.

Influence of bronchopulmonary dysplasia on cerebral blood flow in preterm infants: a prospective study based on arterial spin labeling / 中国当代儿科杂志

OBJECTIVES@#To investigate local cerebral blood perfusion in preterm infants with bronchopulmonary dysplasia (BPD) based on cerebral blood flow (CBF) values of arterial spin labeling (ASL).@*METHODS@#A prospective study was conducted on 90 preterm infants with a gestational age of <32 weeks and a birth weight of <1 500 g who were born in the Department of Obstetrics and admitted to the Department of Neonatology in the Third Affiliated Hospital of Zhengzhou University from August 2021 to June 2022. All of the infants underwent cranial MRI and ASL at the corrected gestational age of 35-40 weeks. According to the presence or absence of BPD, they were divided into a BPD group with 45 infants and a non-BPD group with 45 infants. The two groups were compared in terms of the CBF values of the same regions of interest (frontal lobe, temporal lobe, parietal lobe, occipital lobe, thalamus, and basal ganglia) on ASL image.@*RESULTS@#Compared with the non-BPD group, the BPD group had a significantly lower 1-minute Apgar score, a significantly longer duration of assisted ventilation, and a significantly higher incidence rate of fetal distress (P<0.05). After control for the confounding factors such as corrected age and age at the time of cranial MRI by multiple linear regression analysis, compared with the non-BPD group, the BPD group still had higher CBF values of the frontal lobe, temporal lobe, parietal lobe, occipital lobe, basal ganglia, and thalamus at both sides (P<0.05).@*CONCLUSIONS@#BPD can increase cerebral blood perfusion in preterm infants, which might be associated with hypoxia and a long duration of assisted ventilation in the early stage.

The Nucleus Accumbens CRH-CRHR1 System Mediates Early-Life Stress-Induced Sleep Disturbance and Dendritic Atrophy in the Adult Mouse / 神经科学通报·英文版

Adverse experiences in early life have long-lasting negative impacts on behavior and the brain in adulthood, one of which is sleep disturbance. As the corticotropin-releasing hormone (CRH)-corticotropin-releasing hormone receptor 1 (CRHR1) system and nucleus accumbens (NAc) play important roles in both stress responses and sleep-wake regulation, in this study we investigated whether the NAc CRH-CRHR1 system mediates early-life stress-induced abnormalities in sleep-wake behavior in adult mice. Using the limited nesting and bedding material paradigm from postnatal days 2 to 9, we found that early-life stress disrupted sleep-wake behaviors during adulthood, including increased wakefulness and decreased non-rapid eye movement (NREM) sleep time during the dark period and increased rapid eye movement (REM) sleep time during the light period. The stress-induced sleep disturbances were accompanied by dendritic atrophy in the NAc and both were largely reversed by daily systemic administration of the CRHR1 antagonist antalarmin during stress exposure. Importantly, Crh overexpression in the NAc reproduced the effects of early-life stress on sleep-wake behavior and NAc morphology, whereas NAc Crhr1 knockdown reversed these effects (including increased wakefulness and reduced NREM sleep in the dark period and NAc dendritic atrophy). Together, our findings demonstrate the negative influence of early-life stress on sleep architecture and the structural plasticity of the NAc, and highlight the critical role of the NAc CRH-CRHR1 system in modulating these negative outcomes evoked by early-life stress.

Mechanosensitive Ion Channel TMEM63A Gangs Up with Local Macrophages to Modulate Chronic Post-amputation Pain / 神经科学通报·英文版

Post-amputation pain causes great suffering to amputees, but still no effective drugs are available due to its elusive mechanisms. Our previous clinical studies found that surgical removal or radiofrequency treatment of the neuroma at the axotomized nerve stump effectively relieves the phantom pain afflicting patients after amputation. This indicated an essential role of the residual nerve stump in the formation of chronic post-amputation pain (CPAP). However, the molecular mechanism by which the residual nerve stump or neuroma is involved and regulates CPAP is still a mystery. In this study, we found that nociceptors expressed the mechanosensitive ion channel TMEM63A and macrophages infiltrated into the dorsal root ganglion (DRG) neurons worked synergistically to promote CPAP. Histology and qRT-PCR showed that TMEM63A was mainly expressed in mechanical pain-producing non-peptidergic nociceptors in the DRG, and the expression of TMEM63A increased significantly both in the neuroma from amputated patients and the DRG in a mouse model of tibial nerve transfer (TNT). Behavioral tests showed that the mechanical, heat, and cold sensitivity were not affected in the Tmem63a-/- mice in the naïve state, suggesting the basal pain was not affected. In the inflammatory and post-amputation state, the mechanical allodynia but not the heat hyperalgesia or cold allodynia was significantly decreased in Tmem63a-/- mice. Further study showed that there was severe neuronal injury and macrophage infiltration in the DRG, tibial nerve, residual stump, and the neuroma-like structure of the TNT mouse model, Consistent with this, expression of the pro-inflammatory cytokines TNF-α, IL-6, and IL-1β all increased dramatically in the DRG. Interestingly, the deletion of Tmem63a significantly reduced the macrophage infiltration in the DRG but not in the tibial nerve stump. Furthermore, the ablation of macrophages significantly reduced both the expression of Tmem63a and the mechanical allodynia in the TNT mouse model, indicating an interaction between nociceptors and macrophages, and that these two factors gang up together to regulate the formation of CPAP. This provides a new insight into the mechanisms underlying CPAP and potential drug targets its treatment.

Advances in the role of circular RNA in schizophrenia / 上海交通大学学报（医学版）

Schizophrenia is a complex and severe mental disorder,the precise cause of which remains unknown.Circular RNA(circRNA),a type of non-coding RNA with a loop-like structure,is abundant in eukaryotic cell transcriptomes.Recent advancements in molecular genetics have allowed researchers to gain a better understanding of circRNA's expression profile and biological functions.These molecules play critical roles in various biological processes,including regulation of gene expression,synaptic plasticity,and cognitive flexibility.Due to its high concentration in the mammalian brain,circRNA is involved in neurodevelopment and the maintenance of neural function.Changes in circRNA levels,both within and outside of cells,have been linked to numerous neuro-psychiatric disorders,including schizophrenia.As such,circRNA has a crucial and distinctive function in neuro-psychiatric disorders.Given its characteristics,biological functions,and regulatory roles in diseases,researchers are exploring the abnormal expression of circRNA in schizophrenia and its connection to the onset and progression of the disease.Among them,exosomal circRNA,due to its high stability,disease specificity,and abundant content,is poised to become a potential biological marker for diagnosing schizophrenia.This article provides an extensive overview of the recent circRNA and schizophrenia research,discussing the possibility of using exosomal circRNA as a diagnostic biomarker and therapeutic target for schizophrenia.

Influence of periventricular-intraventricular hemorrhage on cerebral blood flow of preterm infants in the late postnatal period observed by arterial spin labeling: a prospective study / 中华实用儿科临床杂志

Objective:To study the influence of periventricular-intraventricular hemorrhage (PVH-IVH) on cerebral blood flow (CBF) of preterm infants in the late postnatal period using arterial spin labeling (ASL) magnetic resonance imaging (MRI).Methods:From January 2023 to June 2023, 65 preterm infants (gestational age <32 weeks, birth weight <1 500 g) who were born in the Department of Obstetrics, Third Affiliated Hospital of Zhengzhou University and transferred to the Neonatal Intensive Care Unit were included in the prospective study.They were examined by the brain MRI and ASL at the corrected gestational age of 35-40 weeks.According to the results of the brain ultrasound within 1 week after birth, they were divided into the mild IVH group (25 cases) and the non-IVH group (40 cases). The CBF values in regions of interest (frontal lobe, temporal lobe, parietal lobe, occipital lobe, thalamus, and basal ganglia) on ASL images were compared.Multiple linear regression analysis was used to analyze the effect of PVH-IVH on CBF values in different ASL regions of interest, including frontal cortex, temporal cortex, parietal cortex, occipital cortex, thalamus, and basal ganglia.Results:Compared with those of non-IVH group, infants in the mild IVH group presented significantly older gestational age [29.0 (28.5, 30.4) weeks vs.28.2 (27.0, 31.0) weeks, Z=-2.398, P=0.016], higher hematocrit (HCT) in the latest examination prior to the brain MRI [29.6(26.4, 32.3)% vs.27.8 (25.6, 30.5)%, Z=-2.155, P=0.031], and larger body weight at the time of examination [2 015.0 (1 930.0, 2 127.5) g vs.1 950.0 (1 900.0, 1 997.5) g, Z=-3.314, P=0.001]. After adjustment for confounding factors of gestational age at birth, latest HCT and weight at the time of examination, the multivariable linear regression analysis showed that CBF values in the frontal lobe (95% CI: -8.367--4.042; P<0.001), temporal lobe (95% CI: -19.077--2.854; P=0.008), parietal lobe (95% CI: -8.344--3.502; P<0.001), occipital lobe (95% CI: -9.446--3.645; P<0.001), basal ganglia (95% CI: -7.543--1.963; P=0.001) and thalamus (95% CI: -8.051--2.372; P<0.001) were significantly lower in infants of the mild IVH group than those of non-IVH group. Conclusions:At the same corrected gestational age, mild IVH is correlated with low CBF values in local cerebral cortex and subcortical gray matter in premature infants.However, the predictive potential of CBF values in long-term neurological prognosis requires further explorations.
