Referring to the statistical model for the SNP haplotype phasing which was based on the allele frequencies and advised by Browning SR, we investigated and deduced the phasing method of STR haplotype with linkage disequilibrium inpaternity testing preliminarily. Haplotype phasing of two X-STRs in linkage disequilibrium were illustrated. This method provides an idea for the haplotype phasing of STR markers, which is helpful for interpreting the typing results of STR more scientifically and accurately.

Objective:To explore the effect of the NNN-link nursing model combined with International Dysphagia Diet Standardisation Initiative (IDDSI) graded diet management in patients with post-stroke dysphagia.Methods:From May 2021 to May 2023, convenience sampling was used to select 160 post-stroke dysphagia patients admitted to the Second Affiliated Hospital of Wenzhou Medical University. Study subjects were divided into a control group and an observation group using the computer random number table method, with 80 cases in each group. The control group received routine nursing in Department of Neurology, while the observation group was treated with NNN-link nursing model combined with IDDSI graded diet management on this basis. This study compared the Standardized Swallowing Assessment (SSA) and Functional Oral Intake Scale (FOIS) scores of two groups of patients who underwent intervention for 1 day, 7 days and 14 days, and compared the Mini-Nutritional Assessment (MNA), Swallowing Nursing Outcome Assessment, Swallowing-Quality of Life (SWAL-QOL) score, clinical efficacy, and incidence of stroke associated pneumonia (SAP) between two groups before and after intervention.Results:In the end, 79 cases in the observation group and 78 cases in the control group completed the study. After 7 days and 14 days of intervention, the SSA score of the observation group was less than that of the control group, the FOIS score was more than that of the control group, and the nursing compliance was higher than that of the control group, the MNA, nursing outcomes, and SWAL-QOL scores were more than those of the control group, and the total effective rate was higher than that of the control group, the incidence of SAP was lower than that of the control group, and the above differences were statistically significant ( P<0.05) . Conclusions:The combination of NNN-link nursing model and IDDSI graded diet management can improve the swallowing function of post-stroke dysphagia patients, increase clinical efficacy and quality of life, and reduce the incidence of SAP.

Solute carrier (SLC) transporters meditate many essential physiological functions, including nutrient uptake, ion influx/efflux, and waste disposal. In its protective role against tumors and infections, the mammalian immune system coordinates complex signals to support the proliferation, differentiation, and effector function of individual cell subsets. Recent research in this area has yielded surprising findings on the roles of solute carrier transporters, which were discovered to regulate lymphocyte signaling and control their differentiation, function, and fate by modulating diverse metabolic pathways and balanced levels of different metabolites. In this review, we present current information mainly on glucose transporters, amino-acid transporters, and metal ion transporters, which are critically important for mediating immune cell homeostasis in many different pathological conditions.

Orthodontically induced tooth root resorption (OIRR) is a serious complication during orthodontic treatment. Stimulating cementum repair is the fundamental approach for the treatment of OIRR. Parathyroid hormone (PTH) might be a potential therapeutic agent for OIRR, but its effects still lack direct evidence, and the underlying mechanisms remain unclear. This study aims to explore the potential involvement of long noncoding RNAs (lncRNAs) in mediating the anabolic effects of intermittent PTH and contributing to cementum repair, as identifying lncRNA-disease associations can provide valuable insights for disease diagnosis and treatment. Here, we showed that intermittent PTH regulates cell proliferation and mineralization in immortalized murine cementoblast OCCM-30 via the regulation of the Wnt pathway. In vivo, daily administration of PTH is sufficient to accelerate root regeneration by locally inhibiting Wnt/β-catenin signaling. Through RNA microarray analysis, lncRNA LITTIP (LGR6 intergenic transcript under intermittent PTH) is identified as a key regulator of cementogenesis under intermittent PTH. Chromatin isolation by RNA purification (ChIRP) and RNA immunoprecipitation (RIP) assays revealed that LITTIP binds to mRNA of leucine-rich repeat-containing G-protein coupled receptor 6 (LGR6) and heterogeneous nuclear ribonucleoprotein K (HnRNPK) protein. Further co-transfection experiments confirmed that LITTIP plays a structural role in the formation of the LITTIP/Lgr6/HnRNPK complex. Moreover, LITTIP is able to promote the expression of LGR6 via the RNA-binding protein HnRNPK. Collectively, our results indicate that the intermittent PTH administration accelerates root regeneration via inhibiting Wnt pathway. The lncRNA LITTIP is identified to negatively regulate cementogenesis, which activates Wnt/β-catenin signaling via high expression of LGR6 promoted by HnRNPK.
