ObjectiveTo investigate the mechanism of Tangbikang dry paste in the prevention and treatment of type 2 diabetic peripheral neuropathy （DPN） based on the glyoxalase-1 （GLO-1）/advanced glycation end products （AGE）/receptor for advanced glycation end products （RAGE） pathway. MethodsA total of 56 Sprague-Dawley rats were randomly divided， with eight assigned to the normal group. The remaining 48 rats were fed a high-fat diet combined with intraperitoneal injection of streptozotocin （STZ） to induce a type 2 diabetes mellitus （T2DM） model. Based on blood glucose levels， the rats were randomly assigned to the model group， Tanglin group （13.5 mg·kg^-1）， metformin group （135 mg·kg^-1）， and Tangbikang dry paste low-， medium-， and high-dose groups （3， 6， 12 g·kg^-1）. Successful modeling of DPN was confirmed by a decrease in mechanical pain threshold in the model group at week 4. Fasting blood glucose， body weight， and mechanical pain threshold were measured every 4 weeks. After 16 weeks of intervention， the pathological morphology of the sciatic nerve was observed using hematoxylin-eosin （HE） staining. The expression of RAGE， AGE， protein kinase C （PKC）， and collagen （COL） in the sciatic nerve was assessed by immunohistochemistry. The mRNA expression of RAGE， PKC， Toll-like receptor （TLR）， COL， and GLO-1 was detected using real-time quantitative PCR （Real-time PCR）. Serum levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， creatinine （CREA）， urea （UREA）， interleukin-6 （IL-6）， and tumor necrosis factor （TNF）-α were measured by enzyme-linked immunosorbent assay （ELISA）. ResultsCompared with the normal group， the model group showed significantly increased fasting blood glucose （P<0.01）， decreased body weight and mechanical pain threshold （P<0.01）， and elevated serum AST， ALT， CREA， UREA， IL-6， and TNF-α levels （P<0.01）. The expression of RAGE， AGE， and PKC in the sciatic nerve was significantly increased （P<0.01）， while COL expression was decreased （P<0.01）. The mRNA expression of TLR， RAGE， and PKC was upregulated （P<0.01）， whereas COL and GLO-1 mRNA levels were downregulated （P<0.01）. Histological examination showed irregular nerve morphology， axonal alterations， and myelin degeneration. Compared with the model group， fasting blood glucose levels in the Tangbikang dry paste high-dose group at all time points and in the medium-dose group at weeks 4 and 16 were significantly reduced （P<0.05， P<0.01）. No significant changes in body weight were observed across all Tangbikang dose groups. The mechanical pain threshold was elevated at different time points after administration in all Tangbikang groups （P<0.05， P<0.01）. Serum IL-6 and TNF-α levels were decreased in all dose groups （P<0.05， P<0.01）. The expression of RAGE， AGE， and PKC in the sciatic nerve was reduced （P<0.01）， while COL expression was increased （P<0.01）. The mRNA expression of TLR， RAGE， and PKC was downregulated （P<0.01）， whereas GLO-1 mRNA expression was upregulated （P<0.05， P<0.01）. Additionally， COL mRNA expression was significantly increased in the low- and high-dose groups （P<0.01）. Pathological changes in the sciatic nerve were milder in all Tangbikang groups compared to the model group. ConclusionTangbikang dry paste significantly improves DPN， and its mechanism may be associated with the regulation of the GLO-1/AGE/RAGE signaling pathway.

The Spt-Ada-Gcn5-acetyltransferase (SAGA) is an ancillary transcription initiation complex which is highly conserved. The ADA1 (alteration/deficiency in activation 1, also called histone H2A functional interactor 1, HFI1) is a subunit in the core module of the SAGA protein complex. ADA1 plays an important role in plant growth and development as well as stress resistance. In this paper, we performed genome-wide identification of banana ADA1 gene family members based on banana genomic data, and analyzed the basic physicochemical properties, evolutionary relationships, selection pressure, promoter cis-acting elements, and its expression profiles under biotic and abiotic stresses. The results showed that there were 10, 6, and 7 family members in Musa acuminata, Musa balbisiana and Musa itinerans. The members were all unstable and hydrophilic proteins, and only contained the conservative SAGA-Tad1 domain. Both MaADA1 and MbADA1 have interactive relationship with Sgf11 (SAGA-associated factor 11) of core module in SAGA. Phylogenetic analysis revealed that banana ADA1 gene family members could be divided into 3 classes. The evolution of ADA1 gene family members was mostly influenced by purifying selection. There were large differences among the gene structure of banana ADA1 gene family members. ADA1 gene family members contained plenty of hormonal elements. MaADA1-1 may play a prominent role in the resistance of banana to cold stress, while MaADA1 may respond to the Panama disease of banana. In conclusion, this study suggested ADA1 gene family members are highly conserved in banana, and may respond to biotic and abiotic stress.

Objective:To evaluate the effect of nutrition care process and model (NCPM) intervention on the quality of life and nutritional status in patients with non-small cell lung cancer.Methods:A case-control study was conducted among 80 patients with non-small cell lung cancer treated at The 903 Hospital of the PLA Joint Logistics Support Force between January 2023 and February 2024. Based on different intervention methods, these patients were divided into a control group and a study group, with 40 patients in each group. The control group received traditional intervention, while the study group underwent intervention using the NCPM. Negative emotions, anthropometric indices (upper arm muscle circumference, triceps skin thickness, body mass index), blood indices (total serum protein, hemoglobin, serum albumin), quality of life, and immune function indices were compared between the two groups before and after the intervention.Results:After the intervention, the scores on the Self-Rating Depression Scale and Self-Rating Anxiety Scale in the study group were (17.37 ± 1.78) points and (16.48 ± 1.27) points, respectively, which were significantly lower than those in the control group [(26.21 ± 2.01) points, (25.11 ± 1.36) points, t = 20.82, 29.33, both P < 0.001]. The body mass index, triceps skin thickness, and upper arm muscle circumference in the study group were (19.62 ± 0.18) kg/m 2, (9.85 ± 0.23) mm, and (25.81 ± 0.40) cm, respectively, which were significantly higher than those in the control group [(19.32 ± 0.25) kg/m 2, (9.71 ± 0.16) mm, (25.16 ± 0.33) cm, t = 6.16, 3.16, 20.12, all P < 0.05]. The hemoglobin, total serum protein, and serum albumin levels in the study group were significantly higher compared with those in the control group ( t = 3.93, 4.41, 6.15, all P < 0.05). The scores for social function, material life, physical function, and psychological function in the study group were significantly higher than those in the control group ( t = 8.64, 3.44, 3.62, 7.71, all P < 0.05). The study group had significantly higher CD 4+ and CD 4+/CD 8+ values, with (44.12 ± 5.93)% and (1.94 ± 0.43), respectively, compared with the control group [(40.08 ± 5.21)% and (1.52 ± 0.28), t = 3.24, 5.18, both P < 0.05]. The CD 8+ value in the study group was (23.18 ± 2.11)%, which was significantly lower than that in the control group [(27.01 ± 2.73)%, t = 7.02, P < 0.05]. Conclusion:The intervention utilizing the NCPM model effectively enhances the diet structure in patients with non-small cell lung cancer, standardizes the nutritional management process for these patients, and ultimately improves their overall quality of life.

Objective:To analyze the correlation between Cutibacterium acnes (C. acne) ribotypes (RTs) on the skin surface and epidermal barrier function in patients with acne vulgaris.Methods:Sixty patients with acne vulgaris were enrolled in this prospective study from the Department of Dermatology, the Affiliated Hospital of Southwest Medical University from November 2018 to May 2019, including 23 males and 37 females, aged (21.6±2.6) years. According to the General Acne Grading System (GAGS) score, the patients were divided into three groups: 28 mild cases, 14 moderate cases, and 18 severe or above cases. Twenty healthy controls aged 18 to 30 years were recruited in the same period from the community, including 5 males and 15 females, aged (24.2±2.3) years. The VISIA skin testing device was used to detect the percentage of red areas and porphyrins on the facial skin of all subjects. The hydration of the stratum corneum (SCH), transepidermal water loss (TEWL), PH value and the skin surface sebum level on the facial skin were detected by CK system. The RTs of C. acne were further analyzed based on the 16s rDNA sequences. The correlation between the abundance of each RT and epidermal barrier function was analyzed using Pearson correlation analysis.Results:Compared with the healthy controls, the percentage of porphyrins [(41.69±23.10) % vs (61.33±24.27) %, t=2.98, P<0.01] and the percentage of red area [(26.71±17.13) % vs (67.97±15.22) %, t=10.78, P<0.01] decreased in the acne vulgaris patients. Meanwhile, the patients of different severity levels had decreased SCH ( P<0.01), but increased TEWL, pH value, and the skin surface sebum level ( P<0.05) compared to healthy controls. Six different RTs (RT1, RT2, RT7, RT12, RT13 and RT14) were found in both healthy controls and acne vulgaris patients with varying degrees of severity, while there was no statistically significant difference of C. acne abundance between the mild patients and the controls ( P>0.05). As the severity of disease increased, the abundance of the above RTs showed a changing trend, with the gradually decreasing abundance of RT1 and the gradually increasing abundance of RT2, RT7, RT12, RT13, and RT14 (all P<0.05). The abundance of RT1 was negatively correlated with pH value ( r=-0.33, P=0.04) and GAGS score ( r=-0.39, P=0.01). The abundance of RT2 ( r=0.39, P=0.02) and RT7 ( r=0.39, P=0.01) were positively correlated with GAGS score. The abundance of RT13 was negatively correlated with SCH ( r=-0.34, P=0.02) and positively correlated with TEWL ( r=0.30, P=0.05). Conclusions:As the severity of disease increases, the abundance of various RTs of C. acne on the skin surface of acne vulgaris patients shows a trend of gradually increasing or decreasing, and the abundance of differential RTs of C. acne is closely related to the function of the epidermal barrier.

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.

Objective:To explore the relationship between serum albumin (ALB), erythrocyte sedimentation rate (ESR), platelet/lymphocyte ratio (PLR), neutrophil/lymphocyte ratio (NLR) and coronary artery disease in children with Kawasaki disease (KD).Methods:120 KD children diagnosed in the Affiliated Hospital of Jining Medical College from December 2016 to November 2021 were selected as the research objects. They were divided into observation group (KD with coronary artery disease) and control group (KD with coronary artery disease) according to whether they had coronary artery disease, with 60 cases in each group; the serum ALB, ESR, PLR, NLR values of the two groups of children were compared. Receiver operating characteristic (ROC) curve was used to analyze the value of the above indicators in diagnosing KD children with coronary artery disease. The serum ALB, ESR, PLR, NLR levels of KD children with different degrees of coronary artery disease were analyzed.Results:The main manifestations of coronary artery disease in 60 children with KD combined with coronary artery disease were left main coronary artery and left anterior descending branch widening [56.67%(34/60)], left main coronary artery and left anterior descending branch widening [20.00%(12/60)], left anterior descending branch widening [16.67%(10/60)], left main coronary artery widening [11.67%(7/60)]. The serum ALB in the observation group was significantly lower than that in the control group ( P<0.05), and ESR was significantly higher than that in the control group ( P<0.05). There was no significant difference in serum PLR and NLR between observation group and control group (all P>0.05). The sensitivity, specificity and area under curve (AUC) value of serum ALB in diagnosing coronary artery disease in KD children were 73.61%, 78.42% and 0.813 respectively; The sensitivity, specificity and AUC of ESR in diagnosing coronary artery disease in KD children were 88.36%, 83.14% and 0.892 respectively; The sensitivity, specificity and AUC value of ESR combined with ALB in diagnosing coronary artery disease in KD children were 90.67%, 97.54% and 0.953 respectively. Among 60 children with KD complicated with coronary artery disease, 39 were diagnosed as coronary artery dilatation and 21 had coronary artery aneurysm. The serum ALB of children in the coronary artery aneurysm group was significantly lower than that in the coronary artery dilatation group ( P<0.05), and ESR was significantly higher than that in the coronary artery dilatation group ( P<0.05). There was no significant difference in PLR and NLR between the coronary artery aneurysm group and the coronary artery dilatation group (all P>0.05). Conclusions:Children with KD and coronary artery disease have lower serum ALB levels and higher ESR level. The above two indicators are of great value for the diagnosis of children with KD and coronary artery disease.

The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.

Glutamate receptor-like (GLR) is an important class of Ca²⁺ channel proteins, playing important roles in plant growth and development as well as in response to biotic and abiotic stresses. In this paper, we performed genome-wide identification of banana GLR gene family based on banana genomic data. Moreover, we analyzed the basic physicochemical properties, gene structure, conserved motifs, promoter cis-acting elements, evolutionary relationships, and used real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) to verify the expression patterns of some GLR family members under low temperature of 4 ℃ and different hormone treatments. The results showed that there were 19 MaGLR family members in Musa acuminata, 16 MbGLR family members in Musa balbisiana and 14 MiGLR family members in Musa itinerans. Most of the members were stable proteins and had signal peptides, all of them had 3-6 transmembrane structures. Prediction of subcellular localization indicated that all of them were localized on the plasma membrane and irregularly distributed on the chromosome. Phylogenetic analysis revealed that banana GLRs could be divided into 3 subclades. The results of promoter cis-acting elements and transcription factor binding site prediction showed that there were multiple hormone- and stress-related response elements and 18 TFBS in banana GLR. RT-qPCR analysis showed that MaGLR1.1 and MaGLR3.5 responded positively to low temperature stress and were significantly expressed in abscisic acid/methyl jasmonate treatments. In conclusion, the results of this study suggest that GLR, a highly conserved family of ion channels, may play an important role in the growth and development process and stress resistance of banana.
