Objective To investigate the role of trichostatin A(TSA)in regulating CD4+T cell subpopulations during Escherichia coli(E.coli)inflammatory infections.Methods Male mice(8 weeks old,weighing 22~25 g)were randomly divided into 3 groups(n=16):a dimethyl sulfoxide(DMSO)control group,an infection group(DMSO+E.coli),and an intervention group(E.coli+TSA).E.coli was administered via intraperitoneal injection at a concentration of 3×10? CFU/mL to establish an infection model.The E.coli+TSA group was further subdivided into 3 subgroups based on different TSA concentrations(2.5,5.0,10.0 mg/kg).Then the samples were collected at different time points(12,24,48,96 h)after TSA intervention.The efficacy of TSA in treating E.coli-induced inflammatory responses and its relationship with CD4+T cell subsets were evaluated by survival rate observation,body weight monitoring,histopathological staining for small intestine,ELISA detection,transcriptomics sequencing,flow cytometry and RT-qPCR analysis.Results Compared with the E.coli group,5 mg/kg TSA significantly increased survival rate,suppressed body weight loss,improved pathological damage in the small intestinal,reduced serum TNF-α level in 24 h after infection(P<0.000 1),and elevated IL-10 level(P<0.05).Transcriptomic analysis revealed that 5 mg/kg TSA intervention for 24 h modulated the T cell differentiation signaling pathways,including those regulating FoxO,Th17,and Th1/2.Flow cytometry and RT-qPCR results showed that compared to the E.coli group,5 mg/kg TSA down-regulated the expression of the Th17 cell marker RORγt in mice 96 h after infection while significantly up-regulated the expression of the Treg cell marker Foxp3(P<0.05).Conclusion TSA may alleviate bacterial infectious inflammatory diseases by regulating the differentiation of CD4+T cells toward the Treg subset while simultaneously inhibiting their differentiation toward the Th17 subset,thereby suppressing the release of proinflammatory cytokines.

Objectives:
Hypoparathyroidism (HP) is a rare endocrine disorder caused by parathyroid hormone (PTH) defi ciency. The PTH is a candidate gene for familial isolated hypoparathyroidism (FIH). This study aimed to investigate the pathogenicity of two novel rare variants (RVs) ofPTH through in vitro functional study.
Methods:
Targeted next-generation sequencing was used to identify candidate gene mutations. Clinical data were retrospectively collected. Wild-type (WT) PTH was used as a template for site-directed mutagenesis to create mutant eukaryotic expression plasmids, which were transfected into cells. Treated with or without 4-phenylbu tyric acid (4-PBA), the levels of intact PTH (iPTH) and PTH (1-84) were measured by chemiluminescence, and protein expression was assessed using Western blotting.
Results:
Two patients carrying PTH mutations (c.154G > A: p.Val52Ile, c.270G > T: p.Leu90Phe) were identified.Patient 1, a 45-year-old male, presented with carpal and pedal numbness, muscle cramps, and low serum calcium (1.29 mmol/L). Patient 2, a 12-year-old female, had muscle twitches, convulsions, low calcium (1.50 mmol/L), and iPTH of 4 pg/mL. The iPTH or PTH (1-84) levels in the medium transfected with mutant Val52Ile and Leu90Phe PTH decreased by 31%–38%, and 51%–96% compared to WT (allP < 0.05), which were not rescued by 4-PBA. No significant changes in intracellular PTH expression were observed.
Conclusions
In this study, two novel RVs of PTH(Val52Ile and Leu90Phe) were identified that may impair hormone synthesis and secretion. Our study has broadened the mutation spectrum of the PTH and shed light on potential mechanisms underlying FIH.

With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

OBJECTIVE:
Varied acupoint selections represent a potential cause of the uncertainty surrounding the efficacy of acupuncture for knee osteoarthritis (OA). Skin temperature, a guiding factor for acupoint selection, may help to address this issue. This study explored thermal sensitization of acupoints used for the treatment of knee OA.
METHODS:
This cross-sectional case-control study enrolled cases aged 45-75 years with symptomatic knee OA and age- and gender-matched non-knee OA controls in a 1:1 ratio. All participants underwent infrared thermographic imaging. The primary outcome was the relative skin temperature of acupoint (STA), and the secondary outcome was the absolute STA of 11 acupoints. The Z test was used to compare the relative and absolute STAs between the groups. Principal component analysis was used to extract the common factors (CFs, acupoint cluster) in the STAs. A general linear model was used to identify factors affecting the STA in the knee OA cases. For the group comparisons of relative STA, P < 0.0045 (adjusted for 11 acupoints through Bonferroni correction) was considered to indicate statistical significance. For other analyses, P < 0.05 was used as the threshold for statistical significance.
RESULTS:
The analysis included 308 participants, consisting of 151 cases (mean age: [64.58 ± 6.67] years; male: 25.83%; mean body mass index: [25.70 ± 3.16] kg/m2) and 157 controls (mean age: [63.37 ± 5.96] years; male: 26.11%; mean body mass index: [24.47 ± 2.84] kg/m2). The relative STAs of ST34 (P = 0.0001), EX-LE2 (P < 0.0001), EX-LE5 (P = 0.0006), SP10 (P < 0.0001), BL40 (P = 0.0012) and GB39 (P = 0.0037) were higher in the knee OA group. No difference was found in the STAs of ST35, ST36, SP9, GB33 and GB34. Four CFs were identified for relative STA in both groups. The acupoints within each CF were consistent between the groups. The mean values of the relative STAs across each CF were higher in the knee OA group. In the knee OA cases, no factors were observed to affect the relative STA, while age and gender were found to affect the absolute STA.
CONCLUSION
Among patients with knee OA, thermal sensitization occurs in the acupoints of the lower extremity, exhibiting localized and regional thermal consistencies. The thermally sensitized acupoints that we identified in this study, ST34, SP10, EX-LE2, EX-LE5, GB39 and BL40, may be good choices for the acupuncture treatment of knee OA.
