Objective: To analyze the trajectories of body mass index for age z-score (BAZ) and its influencing factors among children with congenital hypothyroidism (CH) based on latent class growth modeling (LCGM), so as to provide the evidence for improving treatment measures and optimizing growth management among children with CH. Methods Children with CH aged 0 to 3 years from the Newborn Disease Screening Center of Shanxi Children's Hospital (Shanxi Maternal and Child Health Hospital) between 2017 and 2022 were selected as the research subjects. Basic information, height and weight data from 3 to 36 months of age, age at treatment initiation, thyroid-stimulating hormone (TSH) levels at diagnosis, and family information were retrospectively collected. BAZ for children with CH at each month of age was calculated based on the WHO Child Growth Standards. The trajectories of BAZ were analyzed using LCGM, and factors affecting the trajectories of BAZ among children with CH were analyzed using a multinomial logistic regression model. Methods: Children with CH aged 0 to 3 years from the Newborn Disease Screening Center of Shanxi Children's Hospital (Shanxi Maternal and Child Health Hospital) between 2017 and 2022 were selected as the research subjects. Basic information, height and weight data from 3 to 36 months of age, age at treatment initiation, thyroid-stimulating hormone (TSH) levels at diagnosis, and family information were retrospectively collected. BAZ for children with CH at each month of age was calculated based on the WHO Child Growth Standards. The trajectories of BAZ were analyzed using LCGM, and factors affecting the trajectories of BAZ among children with CH were analyzed using a multinomial logistic regression model. Results: A total of 299 children with CH were included. There were 140 boys (46.82%) and 159 girls (53.18%). The median of BAZ was 0.50 (interquartile range, 1.68). The LCGM analysis categorized the subjects into three groups: the persistent high-growth pattern group with 24 cases (8.03%), the slow-growth pattern group with 39 cases (13.04%), and the appropriate-growth pattern group with 236 cases (78.93%). Multinomial logistic regression analysis showed that compared to the children with CH in the appropriate-growth pattern group, those who started treatment at the age of 30 to 60 days (OR=0.109, 95%CI: 0.016-0.732; OR=0.166, 95%CI: 0.032-0.852) had a lower risk of persistent high-growth and slow-growth patterns; CH children with TSH levels of 50 to 150 mIU/L at diagnosis (OR=3.554, 95%CI: 1.201-10.514) and those whose paternal had a senior high school/technical secondary school education (OR=2.975, 95%CI: 1.003-8.823) exhibited a higher risk of the persistent high-growth pattern. Conversely, CH children whose paternal reproductive age was 30 to 35 years (OR=0.166, 95%CI: 0.034-0.806) had a lower risk of the persistent high-growth pattern. Conclusions The BAZ trajectory of children with CH aged 0 to 3 years exhibited three patterns: persistent high-growth, slow-growth, and appropriate-growth. The persistent high-growth and slow-growth patterns were associated with treatment timing, TSH levels at diagnosis, paternal reproductive age, and paternal education level. It is recommended to strengthen early treatment interventions and provide family follow-up guidance.

Obesity is a significant risk factor for cancer and is associated with breast cancer metastasis. Nevertheless, the mechanism by which alterations in systemic metabolism affect tumor microenvironment (TME) and consequently influence tumor metastasis remains inadequately understood. Herein, we found that perturbations in circulating metabolites induced by obesity promote metastasis-like phenotypes in breast cancer. Oleoylcarnitine (OLCarn) concentrations were elevated in the serum of obese mice and humans. Administration of exogenous OLCarn induces metastasis-like characteristics in breast cancer cells. Mechanistically, OLCarn directly interacts with the Arg176 site of adenylate cyclase 10 (ADCY10), leading to the activation of ADCY10 and enhancement of cAMP production. Mutations at Arg176 prevent OLCarn from binding to ADCY10, disrupting the ADCY10-mediated activation of cyclic adenosine monophosphate (cAMP) signaling pathway. This activation promotes transcription factor 4 (TCF4)-dependent kinesin family member C1 (KIFC1) transcription, thereby driving breast cancer metastasis. Conversely, the neutralization of both ADCY10 and KIFC1 through knockdown or pharmacological inhibition abrogates the oncogenic effects mediated by OLCarn. Hence, obesity-induced systemic environmental changes lead to the aberrant accumulation of OLCarn within the TME, making it a potential therapeutic target and biomarker for breast cancer.

Objective To investigate the relationship between serum micro RNA(miRNAs)-873 and micro RNA-138-5p expression and tumor immune microenvironment(TIME)and prognosis in patients with non-small cell lung cancer(NSCLC).Methods A total of 108 NSCLC patients(NSCLC group)and 65 healthy volunteers(control group)who were admitted to Ba'nan Hospital Affiliated to Chongqing Medical University from February 2019 to February 2021 were selected.Real-time quantitative fluorescence polymeric chain reaction(qRT-PCR)was used to detect the expression of miR-873 and miR-138-5p in serum,and multiple immunofluorescence staining was used to detect tumor immune microenvironment indicators.Regular follow-up was conducted after discharge.Pearson analyzed the correlation between the expression of miR-873 and miR-138-5p in serum and the TIME index,and Kaplan-Meier and COX proportional risk regression analyzed the relationship between miR-873 and miR-138-5p and the prognosis of NSCLC patients.Results Comparison with control group,the expressions of miR-873(1.02±0.23 vs 3.15±0.82)and miR-138-5p(1.21±0.26 vs 3.54±0.92)in serum of NSCLC group were decreased,and the differences were statistically significant(t=-25.426,-24.769,all P＜0.05).The expressions of serum miR-873 and miR-138-5p of patients with low-to-moderate differentiation in TNM stages Ⅲ to Ⅳ were lower than those with highly differentiated patients in TNM stages Ⅰ to Ⅱ(t=9.615,10.253;6.889,3.361,all P＜0.05).The expressions of miR-873 and miR-138-5p in serum were negatively correlated with the values of PD-1,PD-L1,CD4 and CD8 H(r=-0.418～-0.673,all P＜0.05).The OS survival rate of NSCLC patients with low expression of miR-873 and miR-138-5p was lower than that of those with high expression of miR-873 and miR-138-5p(Log-Rankχ2=4.724,5.607,P＜0.05).TNM stage Ⅲ～Ⅳ was a risk factor for poor prognosis in patients with NSCLC(P＜0.05),and miR-873 and miR-138-5p were protective factors(P＜0.05).Conclusion The expressions of miR-873 and miR-138-5p in serum of NSCLC patients are down-regulated,which is related to TIME and low survival rate.

Objective: To evaluate the effectiveness and safety of modified Xiaoyao powder for postpartum depression (PPD) by conducting a systematic review of randomized controlled trials (RCTs). Methods: The Chinese National Knowledge Infrastructure Databases (CNKI), the Chinese Scientific Journals Database (VIP), Wanfang, Google Scholar, the SinoMed, Embase, Cochrane Library, and PubMed databases were searched from their inception to April 25, 2023. The Cochrane Risk of Bias tool was used to assess the quality of the trials. We applied the risk ratio to present dichotomous data and the mean difference to present continuous data. Data with similar characteristics were pooled for meta-analysis and heterogeneity was assessed using I2. Results: This review included 35 trials involving 2848 participants. The quality of the included studies was low (unclear randomization processes and insufficient reporting of blinding). Participants treated with modified Xiaoyao powder plus Western medicine showed lower Hamilton Depression Scale (HAMD) depression score than those who used Western medicine alone (mean difference = −2.15; 95% confidence interval:−2.52 to 1.78; P < .00001), and higher effective rate (relative risk = 1.19; 95% confidence interval: 1.15 to 1.24; P < .00001), When comparing modified Xiaoyao alone with Western medicine, the HAMD depression score remained low, however, the efficacy rate was higher in the modified Xiaoyao group. Regarding adverse events, the modified Xiaoyao group reported weight gain, nausea, and diarrhea, but no severe adverse events were reported. Conclusion Modified Xiaoyao may help relieve depression in PPD when used alone or in combination with Western medicine, with minor side effects. Therefore, future high-quality, large-sample size RCTs are warranted.

Objective To explore the network structure of anxiety,depression and sleep among individuals under long-term high-altitude exposure.Methods A total of 303 subjects who had resided at high altitudes for more than 6 months on end were selected.The insomnia severity index(ISI),patient health questionnaire(PHQ-9),and generalized anxiety disorder scale(GAD-7)were employed to assess insomnia,depression and anxiety before network analysis was conducted to identify the central and bridge nodes in the symptom network.Results The incidence of moderate or severe depression,anxiety and insomnia were 38.9％[95％confidence interval(CI):33.4％-44.5％],23.1％(95％CI:18.3％-27.9％),and 18.5％(95％CI:14.1％-22.9％),respectively."Noticeability of sleep problems by others"had the highest expected influence centrality,followed by"sleep maintenance""uncontrollable worry""restlessness"and"sleep problems".Five bridge symptoms were identified:"sad mood""sleep problems""restlessness""feeling afraid"and"trouble relaxing".Conclusion Sleep-related symptoms play a crucial role in the overall network structure,serving as both central and bridge nodes.Additionally,the"feeling down or depressed"acts as a bridge node and holds importance in the comorbidity network of anxiety and depression.Targeting these key symptoms through intervention and prevention strategies may improve the psychological well-being of individuals with long-term residence in high-altitude regions.

This study was designed to explore the correlation between alterations in NLRP3 levels and Th17/Treg imbalance in asthmatic mice undergoing epithelial-mesenchymal transition(EMT).A murine model of asthma was established by intraperitoneal injection combined with nebulization of ovalbumin(OVA).Mice were randomly grouped into asthma model group and normal control group.The airway reactivity was detected with non-invasive lung function instrument.Hematoxylin and Eosin(HE)and Masson's trichrome staining were applied to evaluate the histopathological injury of lung tissue and the extent of lung fibrosis;RT-qPCR was applied to detect EMT-related biomarkers(Snail,E-Cadherin,N-Cadherin),the specific transcription factors of T cell subsets(RoRγt,Foxp3)and NLRP3 in lung tissue of mice;Western blot was used to detect the protein expression of E-cadherin,N-Cadherin and NLRP3 in lung tissue of mice.The Th17 and Treg cell populations in the spleen were enumerated via flow cytometry.Furthermore,the expression levels of NLRP3,IL-17 and IL-10 in bronchoalveolar lavage fluid(BALF)were analyzed by Giemsa staining.Compared with the control group,the asthma model group showed higher level of airway resistance,coupled with an obviously decrease in pulmonary ventilation compliance.Pathological alterations in lung tissue were evident,characterized by thickening of the airway epithelium,airway stenosis,infiltration of inflammatory cells,higher expression levels of N-Cadherin and NLRP3 proteins(P<0.05),lower expression level of E-Cadherin(P<0.001)and higher levels of marker genes(Snail and N-Cadherin)in lung tissue.Furthermore,model mice demonstrated higher level of NLRP3 in BALF(P<0.05),higher level of Th17 in spleen,and higher levels of retinoic acid orphan receptor(ROR)-γt mRNA(P<0.05)and Th17-related cytokines(IL-17)(P<0.01).Concurrently,model mice also showed an obviously decrease in the prevalence of Treg cells,Forkhead box Foxp3 mRNA(P<0.001),and Treg-related cytokine IL-10(P<0.05).The results of the Pearson correlation analysis indicated that the level of NLRP3 mRNA was positively correlated the ratio of RoR γt mRNA,but negatively correlated with Foxp3 mRNA in the lung tissue of asthmatic mice.Additionally,NLRP3 in BALF demonstrated a positive correlation with IL-17 and a negative correlation with IL-10.In conclusion,These findings suggest that NLRP3 may trigger bronchial EMT by exacerbating the immune imbalance of Th17/Treg cells.

Objective·To investigate the effects of multiple sevoflurane exposures on the proliferation and differentiation of primary oligodendrocytes.Methods·Oligodendrocyte precursor cells(OPCs)were extracted from the cortex of rats on the day of birth and cultured in vitro.The cells were divided into control and sevoflurane groups.To simulate the clinical situation of sevoflurane exposure,cells in the sevoflurane group were exposed to 3%sevoflurane for 3 consecutive days,2 h for each time.After the OPCs were differentiated and matured,immunofluorescence staining and Western blotting were used to detect the expression of myelin basic protein(MBP)and the myelin-associated glycoprotein(MAG).Cell proliferation assays(BrdU and Ki67)and a cell viability assay(CCK8)were used to detect the effects of sevoflurane on the proliferation ability of OPCs and the survival rate of oligodendrocytes.Western blotting was used to detect the protein content of caspase-3.Lentiviral transfection technology was used to overexpress YTH N6-methyladenosine RNA binding protein F1(YTHDF1)in OPCs,and then CCK8 was used to detect cell proliferation and survival.Results·Immunofluorescence results showed that multiple sevoflurane exposures led to a decrease in the number of primary oligodendrocytes expressing mature myelin surface markers(MBP,MAG);Western blotting results showed that these exposures led to upregulation of caspase-3 expression in primary OPCs;CCK8 results showed that the survival rate of primary OPCs decreased with the increase in the number of sevoflurane treatments;however,BrdU and Ki67 staining results showed that the proliferation ability of primary OPCs was enhanced after sevoflurane exposure.In addition,overexpression of YTHDF1 could partially improve the decreased survival rate of primary OPCs caused by multiple sevoflurane exposures(all P<0.05).Conclusion·Multiple sevoflurane exposures impair the myelinating ability and survival rate of primary oligodendrocytes,manifested by apoptosis of some primary OPCs.In contrast,sevoflurane exposure compensatorily increases the proliferation ability of surviving primary OPCs.

During the procedure, made into transverse double bone tunnels on the base of the distal phalanx with 0. 8 mm Kirschner wire, bundling bone fragment with figure-of-eight suture through double bone tunnels, then fixed with Kirschner wire elastic compression. Removal of the Kirschner wire 3 weeks after the procedure, the active flexion and extension range of the joints of the affected finger and the corresponding finger were measured at the last follow-up, then the range of motion (ROM) of the distal interphalangeal joint (DIPJ) and total action movement (TAM) of the fingers (affected and healthy finger) were recorded. The curative effects were evaluated according to the TAM system of the American Association of Hand Surgeons, including 4 grades: excellent, good, fair, and poor. SPSS 13. 0 software was used for statistical analysis of the data, and the measurement data conforming to normal distribution were expressed as Mean ± SD. The ROM of DIPJ and TAM of the affected finger were compared with the corresponding healthy finger 6 months after surgery by a paired sample t test. P<0. 05 indicates that the difference is statistically significant. Results:A total of 30 patients (30 digits) were enrolled, including 19 males and 11 females, and the age ranged from 18 to 62 years old, with an average age of 31 years old. The time from injury to operation was 24 to 65 days (mean of 35 days) . According to Wehbe and Schneider classification, there were 8 cases of type Ⅰa, 6 cases of type Ⅰb, 7 cases of type Ⅱa, 5 cases of type Ⅱb, 2 cases of type Ⅲa and 2 cases of type Ⅲb. All incisions healed well, the intraoperative blood loss was minimal, with no infection. All 30 cases were followed up for 6 to 7 months. All fractures were well aligned and healed, malformed fingers were completely corrected, and no needle tunnel infection or needle breakage were observed. At the last follow-up, the differences of the ROM of the DIPJ [ (30. 2±3. 5) °vs. (30. 4±3. 3) °, t=2. 57, P=0. 463] and the TAM [ (235. 3± 3. 6) ° vs. (237. 7± 4. 2) °, t=1. 78, P= 0. 247 ] between the affected and healthy fingers were not statistically significant. Finger function assessment: 27 cases were excellent, and 3 cases were good, and the excellent and good rate was 100%. Conclusion:Satisfactory therapeutic outcome for the treatment of chronic bong mallet finger deformity can be achieved by bundling bone fragment with figure-of-eight suture through double bone tunnels. It is an effective and practical method.
