Objective:To observe the effects of nutritional status on the surgical outcomes, nutritional indicators, and renal anemia of maintenance hemodialysis patients with secondary hyperparathyroidism undergoing parathyroidectomy.Methods:A retrospective study was conducted on 35 patients who underwent maintenance hemodialysis with secondary hyperparathyroidism at Huadu District People′s Hospital of Guangzhou from January 2016 to January 2021. All patients underwent total parathyroidectomy with autologous forearm transplantation due to ineffective drug treatment. Before surgery, patients were divided into three groups based on their nutritional status scores: no malnutrition group (0-1 points), mild malnutrition group (2-4 points), and moderate to severe malnutrition group (5-12 points). The changes in serum parathyroid hormone, blood calcium, blood phosphorus, blood albumin, and other indicators were observed at different time points before and after surgery in different groups of patients.Results:The serum parathyroid hormone, blood phosphorus, and calcium phosphorus product of maintenance hemodialysis patients with different nutritional status who underwent parathyroidectomy at 3, 6, and 12 months were significantly decreased compared with preoperative levels, and the differences were statistically significant (all P<0.05). There were no significant changes in albumin, lymphocyte count, and total cholesterol levels in patients without malnutrition at 3, 6, and 12 months after surgery compared with preoperative levels (all P>0.05); The lymphocyte count of patients with mild malnutrition increased significantly at 6 and 12 months after surgery compared to preoperative levels (all P<0.05). The levels of albumin and total cholesterol in patients with moderate to severe malnutrition increased significantly at 3, 6, and 12 months after surgery compared with preoperative levels (all P<0.05). The Hb levels of patients without malnutrition and those with mild malnutrition increased significantly at 6 and 12 months after surgery compared with preoperative levels (all P<0.05); The Hb levels of patients with moderate to severe malnutrition increased significantly at 3, 6, and 12 months after surgery compared with preoperative levels (all P<0.05). Conclusions:Nutritional status affects the long-term outcomes of parathyroidectomy in hemodialysis patients, and parathyroidectomy can significantly improve the nutritional and anemia status of hemodialysis patients with secondary hyperparathyroidism. This effect is more pronounced in patients with moderate to severe malnutrition before surgery.

Objective:To investigate the efficacy and safety of intravenous thrombolysis and antiplatelet therapy in patients with stroke warning syndrome (SWS), as well as influencing factors of the outcome in patients with SWS.Method:Patients with SWS admitted to the 521 st Hospital of Ordnance Group from June 1, 2018 to December 31, 2023 were retrospectively included. Some patients were treated with ateplase intravenous thrombolysis, followed by oral antiplatelet therapy; some patients only received antiplatelet therapy. The main outcome measure was the modified Rankin Scale score at 90 days after onset, with a score of 0-2 defined as good outcome. Results:A total of 35 patients with SWS were included, including 26 males (74.3%) with an age of 58.29±11.06 years. Nineteen patients (54.3%) received intravenous thrombolysis, and 27 (77.1%) had good outcome at 90 days. There was no statistically significant difference in demographic, baseline data, and good outcome between the intravenous thrombolysis group and the antiplatelet therapy group. One patient had new stroke and one had transient ischemic attack in the intravenous thrombolysis group. There were statistically significant differences in ABCD2 score, systolic blood pressure, low-density lipoprotein cholesterol, fasting blood glucose, highest National Institutes of Health Stroke Scale (NIHSS) score at onset, and symptom duration between the good outcome group and the poor outcome group (all P<0.05). Conclusions:The efficacy of intravenous thrombolysis is similar to that of antiplatelet drugs alone in treating SWS. ABCD2 score, systolic blood pressure, low-density lipoprotein cholesterol, fasting blood glucose, highest NIHSS score at onset, and duration of symptoms may be influencing factors for the outcome of patients with SWS.

Objective:To determine the clinical factors affecting Central lymph node metastases (CLNM) of single Papillary thyroid carcinoma (PTC). To predict the value of age for CLNM under different genders and the status of Hashimoto’s thyroiditis (HT) .Methods:The clinical data of 4 115 patients with PTMC (≤10.0 mm) and 664 patients with PTC (> 10.0 mm) in Hangzhou First People’s Hospital affiliated to Westlake University Medical School from Jan. 2010 to Aug. 2023 were retrospectively analyzed, and the independent risk factors of PTMC and PTC CLNM were identified by univariate and multivariate logistic regression analysis. According to different gender and HT status, the patients were divided into male group, female group, HT group and non-HT group. The optimal age threshold and diagnostic efficacy of CLNM in each subgroup were determined by Receiver operating characteristic area under the curve (AUC) .Results:The proportion of CLNM in 3451 PTMCs and 664 PTCs was 27.2% (937/3451) and 58.9% (391/664) ( χ2=256.565, P<0.050), respectively. Univariate and multivariate regression analysis showed that larger tumor ( OR 1.230), male ( OR 2.085), older age ( OR 0.960) and HT ( OR 0.697) were independent predictors of the occurrence of CLNM in PTMC. Only male ( OR 1.460) and older ( OR 0.963) PTC were independently associated with CLNM. Subgroup analysis showed that the age-predicted AUC of CLNM in male, HT and non-HT patients in PTC were higher than that of PTMC, which were 0.642-0.689 and 0.635-0.659, respectively. The age thresholds of female, HT and non-HT subgroups in PTC were lower than those in PTMC, which were 38.5 to 39.5 years old and 41.5 to 42.5 years old, respectively. Conclusions:Larger tumor, male, older patients and HT can independently predict the risk of CLNM in PTMC, while only male and older people can independently predict the risk of CLNM in PTC. There are certain differences in the age of CLNM occurrence between PTMC and PTC patients with different genders and HT combination status. It is of great significance to correctly understand these differences for providing personalized clinical treatment.

Objective:To investigate symptoms of anxiety and depression among primary and middle school students quarantined in hotels during the COVID-19 epidemic.Methods:Anxiety and depression symptoms among 726 primary and middle school students quarantined in hotels were investigated with The Screen for Child Anxiety Related Emotional Disorders(SCARED)and Depression Self-rating Scale for Children(DSRSC)from September to October 2022 in Chifeng City,Inner Mongolia Autonomous Region.There were 624 students completed investi-gation with response rate of 86％.The positive score of SCARED was ≥23 and DSRSC was ≥ 15.Results:The detection rates of anxiety and depression were 17.9％and 15.4％respectively.The detection rates of anxiety and depression were higherin middle school students than inprimary school students(Ps＜0.05).The scores of general-ized anxiety and social phobia factors were higher in female students than in male students(Ps＜0.05).The scores of dissociative anxiety factor and depression were higher in middle school students than in primary school students(Ps＜0.05).Conclusion:During the COVID-19 epidemic,middle school students quarantined in hotels are more likely to have anxiety and depression symptoms than primary school students,and female students are more likely to have anxiety symptoms than male students.

Small for gestational age (SGA) infants are more likely to experience neurocognitive impairments compared to appropriate for gestational age (AGA) infants. This paper reviews recent research on the neurocognitive development of SGA children. SGA can lead to a "brain-sparing effect" due to growth restriction, which may affect cerebral blood flow and brain structure. However, this does not guarantee normal brain development. Restrictive blood flow can result in changes in brain structure, such as reduced total white matter and gray matter volume in various brain regions, including the cerebral cortex, hippocampus and cerebellum, ultimately leading to decreased head circumference. SGA children also exhibit lower scores in all neurocognitive domains, including intelligence, attention, memory, and executive function. This may result in poor academic performance and an increased risk of social, behavioral, and neurological problems, such as cerebral palsy, epilepsy, visual and hearing impairments, as well as comorbidities like attention deficit hyperactivity disorder(ADHD), autism spectrum disorder(ASD), anxiety, depression, and schizophrenia. Several risk factors for SGA-related neurocognitive impairments have been identified, including gestational hypertension, abnormal gestational weight, smoking, and catch-up growth. Studies have shown that the best interventions to improve cognitive dysplasia include nutrient supplementation, continued breastfeeding, high-quality education, and appropriate early intervention (responsive parenting) are effective in improving cognitive outcomes for SGA children.

【Objective】 To explore the correlation between different feeding styles of caregivers and diet quality of children with nutritional problems, in order to provide reference for making effective feeding guidance and intervention strategy. 【Methods】 From January 2022 to August 2023, 2- to 6-year-old children who had been enrolled in kindergartens or nurseries and their caregivers from the combined outpatient department of Child Healthcare and Nutrition in Shanghai Children′s Hospital were selected into this study.The amount of dinner served and consumed was obtained through the three-day dinner intake survey, and the Chinese Healthy Eating Index (CHEI) was calculated.Feeding styles were divided into four groups through the Caregiver Feeding Style Questionnaire.Pearson correlation analysis was used to determine the correlation between served and consumed CHEI score.Chi-square test, t-test and ANOVA were used to compare the differences in CHEI score for dinner consumed in children with different feeding styles. 【Results】 1) Totally 133 parent-child pairs were included in this study.There were 68 boys (51.1%) and 65 girls (48.9%), with an average age of (4.6±0.6) years.2) CHEI scores for dinner served was highly correlated with that for dinner consumed (r=0.90, P<0.05).There was statistically significant difference between the CHEI score for dinner served and consumed by authoritative and authoritarian feeding styles (t=2.538, 1.732, P<0.05).3) After adjusting body shape, children in the authoritative feeding style actually completed a significantly higher diet quality CHEI score than those in the authoritarian feeding style (P<0.05).4)Authoritative and indulgent feeding styles had statistical differences in the distribution of children′s body size (χ²=13.587, P=0.035). 【Conclusions】 Parents with authoritarian feeding style and indulgent feeding style have worse control over their children′s dietary completion.Children with authoritative feeding style have higher dietary quality than those with authoritarian feeding style.Children with indulgent feeding style may have a higher proportion of non-low weight than those with authoritative feeding style.Although feeding style could not reverse the outcome of body shape deviation in children with disease, it may have some positive effects.

In recent years, the effects of air pollutants on the neurodevelopmental disorders in children have received widespread attention. Early life is a critical period of rapid brain development, and exposure to air pollutants during this period may permanently alter brain function. This paper reviewed the epidemiological studies on the association between exposure to air pollutants during early life and children's neurodevelopmental disorders in recent years, with focus on outdoor air pollutants (e.g., PM_2.5, PM₁₀, NOx, and CO) and indoor air pollutants (e.g., cooking oil fumes, tobacco and mosquito incense smoke, and formaldehyde from home decoration), and summarized their possible biological mechanisms. Most studies indicate that pollutants in different periods and at different levels of exposure during early life can negatively affect children's neurodevelopment and that there may be a dose-response relationship between certain air pollutants and children's neurodevelopment. Current research on the effects of indoor air pollutants on children's neurodevelopment focus on exposure to tobacco smoke, while other indoor air pollutants such as cooking oil fumes and organic compounds produced by interior decorative materials are less well reported and their underlying biological mechanisms are not yet clear. Further epidemiological studies, animal and cellular experiments are needed to provide evidence for the neurodevelopmental toxicity of air pollutant exposure in the future, aiming to provide a theoretical basis for environmental eugenics and promote healthy development of children.

ObjectiveTo explore the effects of after-school tutoring for school-age children on their emotions and behaviors， and to provide a basis for developing after-school tutoring and psychological support strategies for school-age children. MethodsFour elementary schools in a district of Shanghai were selected by simple random sampling method. Whole group sampling was conducted by class， and parents of students were surveyed by general questionnaire and the scale of strengths and difficulties. Information was collected on the basic conditions of children and families and the results were compared and analyzed. ResultsThis study showed that 88.26% of children attended extracurricular classes， of which 26.16% attended 3 or more classes， 42.5% attended cultural classes， 28.3% attended sports classes， and 59.8% attended art classes. Children who did not attend classes had higher pro-social scores. Children who attended reading class had lower scores for emotional problems that was a protective factor for emotional problems. Children who chose extracurricular programs in sports and reading also had lower overall scores for difficulties. Excessive use of electronic devices by school-age children on weekdays or weekends had a negative effect on emotional and conduct problem scores regardless of whether they chose extracurricular programs. It appeared that the choice of cultural programs， art programs and different levels of exercise intensity had no effect on children's emotions and behaviors. ConclusionFor children with low pro-social level， extracurricular classes should be carefully selected. For extracurricular classes， more reading and sports-related courses can be considered， which have positive effects on school-age children’s emotions and behaviors. Regardless of the choice of extracurricular classes， try to avoid excessive online classes.

As known, the benefits of photothermal therapy (PTT) are greatly limited by the heat tolerance of cancer cells resulting from overexpressed heat shock proteins (HSPs). Then HSPs further trigger the formation of stress granules (SGs) that regulate protein expression and cell viability under various stress conditions. Inhibition of SG formation can sensitize tumor cells to PTT. Herein, we developed PEGylated pH (low) insertion peptide (PEG-pHLIP)-modified hollow copper sulfide nanoparticles (HCuS NPs) encapsulating the SG inhibitor ISRIB, with the phase-change material lauric acid (LA) as a gate-keeper, to construct a pH-driven and NIR photo-responsive controlled smart drug delivery system (IL@H-PP). The nanomedicine could specifically target slightly acidic tumor sites. Upon irradiation, IL@H-PP realized PTT, and the light-controlled release of ISRIB could effectively inhibit the formation of PTT-induced SG to sensitize tumor cells to PTT, thereby increasing the antitumor effect and inducing potent immunogenic cell death (ICD). Moreover, IL@H-PP could promote the production of reactive oxygen species (ROS) by tumor-associated macrophages (TAMs), repolarizing them towards the M1 phenotype and remodeling the immunosuppressive microenvironment. In vitro/vivo results revealed the potential of PTT combined with SG inhibitors, which provides a new paradigm for antitumor and anti-metastases.

Glioblastoma (GBM) is the most common and aggressive malignant brain tumor in adults and is poorly controlled. Previous studies have shown that both macrophages and angiogenesis play significant roles in GBM progression, and co-targeting of CSF1R and VEGFR is likely to be an effective strategy for GBM treatment. Therefore, this study developed a novel and selective inhibitor of CSF1R and VEGFR, SYHA1813, possessing potent antitumor activity against GBM. SYHA1813 inhibited VEGFR and CSF1R kinase activities with high potency and selectivity and thus blocked the cell viability of HUVECs and macrophages and exhibited anti-angiogenetic effects both in vitro and in vivo. SYHA1813 also displayed potent in vivo antitumor activity against GBM in immune-competent and immune-deficient mouse models, including temozolomide (TMZ) insensitive tumors. Notably, SYHA1813 could penetrate the blood-brain barrier (BBB) and prolong the survival time of mice bearing intracranial GBM xenografts. Moreover, SYHA1813 treatment resulted in a synergistic antitumor efficacy in combination with the PD-1 antibody. As a clinical proof of concept, SYHA1813 achieved confirmed responses in patients with recurrent GBM in an ongoing first-in-human phase I trial. The data of this study support the rationale for an ongoing phase I clinical study (ChiCTR2100045380).
