AIM:To investigate the predictive value of aqueous humor stromal cell-derived factor-1(SDF-1)and epithelial neutrophil-activating peptide-78(ENA78)for visual impairment following vitrectomy in patients with diabetic retinopathy(DR).METHODS: Patients with DR who underwent vitrectomy in the ophthalmology department of our hospital from March 2022 to March 2024 were enrolled as study group. According to the results of uncorrected visual acuity examination during the 1-year follow-up after surgery, they were further divided into visual impairment group and good visual acuity group. In addition, patients with cataracts who were treated in our hospital during the same period were recruited as control group. The levels of SDF-1 and ENA78 in aqueous humor were detected by enzyme-linked immunosorbent assay(ELISA). Pearson correlation analysis was used to evaluate the correlation of indicators. Multivariate Logistic regression analysis was performed to identify the influencing factors of postoperative visual impairment in DR patients. Relative risk analysis was conducted to assess the impact of different aqueous humor SDF-1 and ENA78 levels on postoperative visual impairment in DR patients. Receiver operating characteristic(ROC)curve analysis was applied to determine the predictive value of aqueous humor SDF-1 and ENA78 levels for postoperative visual impairment in DR patients.RESULTS: Totally 156 cases(156 eyes)were enrolled in the study group, including 87 males and 69 females, with a mean age of 60.65±8.91 years old; and 91 cases(91 eyes)were enrolled in the control group, including 53 males and 38 females, with a mean age of 58.72±8.43 years old. The levels of SDF-1 and ENA78 in aqueous humor of the study group were significantly higher than those of the control group(P<0.001). According to the results of uncorrected visual acuity during the 1-year follow-up after surgery, the study group was further divided into the visual impairment group(n=49)and the good visual acuity group(n=107), including 28 males and 21 females in the visual impairment group, with a mean age of 63.73±7.41 years, and 59 males and 48 females in the good visual acuity group, with a mean age of 59.24±8.47 years. The age and glycated hemoglobin(HbA1c)levels of the visual impairment group were higher than those of the good visual acuity group(all P<0.05). Compared with the good visual acuity group, the levels of SDF-1 and ENA78 in aqueous humor of the visual impairment group were significantly elevated(all P<0.05). A positive correlation was found in the study group between the levels of SDF-1, ENA78 in aqueous humor and HbA1c(r=0.314, 0.362, all P<0.05). Elevated levels of aqueous humor SDF-1(OR=2.936, 95% CI: 1.628-5.296)and ENA78(OR=3.092, 95% CI: 1.738-5.502)were identified as risk factors for postoperative visual impairment in DR patients(all P<0.05). High levels of SDF-1 and ENA78 increased the risk of postoperative visual impairment by 1.958-fold and 2.030-fold compared with the low-level groups, respectively; the area under the curve(AUC)of combined detection of aqueous humor SDF-1 and ENA78 for predicting postoperative visual impairment in DR patients was 0.936, which was superior to the predictive value of SDF-1 or ENA78 alone(Zcombination-SDF-1=2.850, Zcombination-ENA78=2.445, all P<0.05).CONCLUSION: Elevated levels of aqueous humor SDF-1 and ENA78 are risk factors for postoperative visual impairment in DR patients, and the combined detection of SDF-1 and ENA78 has high clinical application value for predicting postoperative visual impairment in DR patients.

AIM: To investigate the correlation of serum leukocyte-derived chemotaxin 2(LECT2)and complement C1q/tumor necrosis factor-related protein 5(CTRP5)with diabetic retinopathy(DR).METHODS:A single-center cross-sectional analysis was conducted on 138 patients with type 2 diabetes mellitus(T2DM)admitted to our hospital from April 2023 to April 2025. According to the diagnostic results, they were divided into a non-DR group(60 cases)and a DR group(78 cases). The DR group was further divided into a proliferative DR(PDR)group(29 cases)and a non-proliferative DR(NPDR)group(49 cases). Pearson correlation analysis was used to assess the correlation of LECT2 and CTRP5 with glucose-lipid metabolism indicators. Logistic regression analysis was conducted to identify the influencing factors for the occurrence of DR in T2DM patients. ROC curve analysis was performed to evaluate the diagnostic value of serum LECT2 and CTRP5 for DR in T2DM patients.RESULTS: A comparison of general patient data between the two groups showed no significant differences. The DR group had higher serum levels of LECT2, CTRP5, total cholesterol(TC), triglycerides(TG), low-density lipoprotein cholesterol(LDL-C), and homeostatic model assessment of insulin resistance(HOMA-IR)than the non-DR group, while high-density lipoprotein cholesterol(HDL-C)was lower(all P<0.05). The serum levels of LECT2 and CTRP5 in the PDR group were higher than those in the NPDR group(all P<0.05). Serum LECT2 and CTRP5 positively correlated with TC, TG, LDL-C, and HOMA-IR, and negatively correlated with HDL-C(all P<0.001). Logistic results showed that duration of diabetes, TC, TG, LDL-C, HOMA-IR, LECT2, and CTRP5 were risk factors for DR occurrence in T2DM patients(all P<0.05). The ROC curve showed that the AUCs for serum LECT2, CTRP5 alone, and combined in diagnosing DR in T2DM patients were 0.830, 0.839, and 0.915, respectively. The AUC for the combined diagnosis was higher than that of LECT2 or CTRP5 alone according to the DeLong test(Z=2.818, 2.824, P=0.015, 0.012).CONCLUSION:Serum LECT2 and CTRP5 levels are closely related to the development of DR in T2DM patients, and joint detection has certain clinical value in diagnosing DR in T2DM patients.

OBJECTIVE To explore the effect of fluconazole on proteomics of Trichosporon asahii so as to reveal the responding process of T.asahii to fluconazole stress and the resistance mechanisms to azoles on the protein level.METHODS T.asahii AS 2.2174 was chosen as the research subject,the minimum inhibitory concentration(MIC)of fluconazole was determined by broth microdilution assay.The protein abundance of T.asahii was detec-ted by means of tandem mass tag(TMT)technique combined with liquid chromatography-tandem mass spectrom-etry(LC-MS/MS)before and after the treatment with fluconazole(1× MIC).The differentially expressed pro-teins(DEPs)were identified based on the screening standards of fold change ≥1.20 or ≤0.83 and P＜0.05.Gene ontlogy(GO)and Kyoto encyclopedia of genes and genomes(KEGG)enrichment analysis were performed for the DEPs so as to understand the biological property of the DEPs and the major biological pathways that the DEPs in-volved in.Finally,the targeted validation was carried out for the targeted differentially expressed proteins by using multiple reaction monitoring(MRM).RESULTS The MIC of fluconazole to T.asahii AS 2.2174 was 8 μg/ml.Totally 196 DEPs were identified,including 93 upregulated DEPs and 103 downregulated DEPs.The function en-richment analysis showed that the DEPs mainly participated in synthesis and metabolism of sterols,drug metabo-lism,stress response,energy metabolism and intertranslation.The targeted DEPs showed the consistent expres-sion trends in MRM target validation and TMT-LC-MS/MS.CONCLUSIONS The protein abundance of T.asahii has remarkable change under the fluconazole stress.The bioinformatics analysis reveals the complicated molecular mechanisms of T.asahii in response to the fluconazole stress,which may offer valuable ideas for understanding the drug resistance to azoles and developing new drug targets.

The global incidence of head and neck cancer (HNC) is rising, with over 60% of patients presenting at a locally advanced stage. Radiotherapy remains a cornerstone of HNC treatment, and advancements in modern techniques and concurrent chemotherapy have improved local control and survival rates of HNC patients. However, these benefits also bring challenges in the management of toxicities. Due to the proximity of salivary glands and tumors, especially the highly radiosensitive parotid and submandibular glands, this condition is among the most common adverse effects of radiotherapy. Radiation damages acinar cells and ducts, causing glandular atrophy, fibrosis, and reduced saliva secretion, thereby leading to xerostomia and related complications. The risk and severity of injury are associated with the radiation dose and volume affecting the glands. Prevention and management strategies emphasize precise radiotherapy planning, target optimization, and supportive care. Emerging multimodal imaging techniques offer potential for non-invasive prediction and early diagnosis and treatment of radiation-induced salivary gland injury. Future research in regenerative medicine, tissue engineering, and molecular biology aims to elucidate molecular mechanisms, such as signaling pathways and genomics, facilitating personalized strategies to mitigate radiotherapy-induced toxicities and enhance the quality of life of patients.

Skeletal class Ⅱ malocclusion is characterized by maxillary protrusion,mandibular retrognathia,or a combination of both,and often accompanied by vertical dimensional discrepancies;treatment is complex,and combined orthodontic-orthognathic surgery is needed for the adult patients.Clear aligner therapy has gradually been applied in complex orthodontic cases.However,limited cases have been reported domestically and internationally regarding the application of clear aligner therapy combined with orthognathic surgery.This article presented a case of a patient with skeletal class Ⅱ high-angle malocclusion treated with the combined therapy and analyzed the clinical efficacy of the treatment appraoch to provide reference for the clinical practice.Extraction of impacted wisdom teeth 18,28,38,and 48,as well as orthodontic teeth 15,25,34,and 44,was performed in stages before orthodontic treatment.Clear aligner therapy was used for preoperative orthodontics.In sagittal plane,a super-complete class Ⅱ canine and molar relationship and a 13-14 mm overjet of the anterior teeth were established.The maxillary and mandibular arch morphology was matched horizontally.The orthognathic surgery included maxillary LeFort Ⅰ osteotomy,bilateral sagittal split ramus osteotomy(BSSRO)and chinplasty.Fine occlusal adjustment was conducted after operation.After treatment,the skeletal relationship between upper and lower jaw was corrected to normal;subspinale-nasion-supramental angle(ANB)was improved from 12.3° to 4.7°;the patient established the class Ⅰ canine and molar relationship,with normal overjet and overbite;root parallelism was good and there was no obvious root resorption;the facial soft tissue profile was significantly improved,and nasion-subnasale-pogonion angle(N-Sn-Pg)was improved from 143.9° to 162.8°.The curative effect was stable 1 year after operation.Clear aligner therapy can efficiently complete combined orthodontic and orthodontic surgery in the complex cases.Compared with the fixed appliance,it is more beneficial to the patients'need for beauty and the maintenance of periodontal health.

The grade of histological severity is a determining factor to evaluate the prognosis and survival rate in primary biliary cholangitis (PBC). However, liver biopsy is limited by sampling error, invasiveness, high cost, and poor compliance. Therefore, in order to overcome the limitations of liver biopsy, some non-invasive evaluation methods have been studied and applied to evaluate the progression of liver fibrosis in PBC. The prognostic score can be calculated using routine laboratory test results obtained at the time of diagnosis, which are characterized by their simplicity, affordability, ease of acquisition, and superior reproducibility. Recent studies have reported that the prognostic score can be employed as a non-invasive liver fibrosis model to diagnose the liver fibrosis stage in PBC and predict the transplant-free survival rate, in addition to being used to evaluate the patient prognosis and transplant-free survival (TFS). This paper reviews, summarizes, and explores the research progress of different prognostic scores as non-invasive liver fibrosis models via their diagnostic performance and predictive accuracy for PBC.

The thalamic reticular nucleus (TRN) plays a crucial role in regulating sensory encoding, even at the earliest stages of visual processing, as evidenced by numerous studies. Orientation selectivity, a vital neural response, is essential for detecting objects through edge perception. Here, we demonstrate that somatostatin (SOM)-expressing and parvalbumin (PV)-expressing neurons in the TRN project to the dorsal lateral geniculate nucleus and modulate orientation selectivity and the capacity for visual information processing in the primary visual cortex (V1). These findings show that SOM-positive and PV-positive neurons in the TRN are powerful modulators of visual information encoding in V1, revealing a novel role for this thalamic nucleus in influencing visual processing.

Osteoporosis is a prevalent skeletal condition characterized by reduced bone mass and strength, leading to increased fragility. Buqi-Tongluo (BQTL) decoction, a traditional Chinese medicine (TCM) prescription, has yet to be fully evaluated for its potential in treating bone diseases such as osteoporosis. To investigate the mechanism by which BQTL decoction inhibits osteoclast differentiation in vitro and validate these findings through in vivo experiments. We employed MTS assays to assess the potential proliferative or toxic effects of BQTL on bone marrow macrophages (BMMs) at various concentrations. TRAcP experiments were conducted to examine BQTL's impact on osteoclast differentiation. RT-PCR and Western blot analyses were utilized to evaluate the relative expression levels of osteoclast-specific genes and proteins under BQTL stimulation. Finally, in vivo experiments were performed using an osteoporosis model to further validate the in vitro findings. This study revealed that BQTL suppressed receptor activator of NF-κB ligand (RANKL)-induced osteoclastogenesis and osteoclast resorption activity in vitro in a dose-dependent manner without observable cytotoxicity. The inhibitory effects of BQTL on osteoclast formation and function were attributed to the downregulation of NFATc1 and c-fos activity, primarily through attenuation of the MAPK, NF-κB, and Calcineurin signaling pathways. BQTL's inhibitory capacity was further examined in vivo using an ovariectomized (OVX) rat model, demonstrating a strong protective effect against bone loss. BQTL may serve as an effective therapeutic TCM for the treatment of postmenopausal osteoporosis and the alleviation of bone loss induced by estrogen deficiency and related conditions.
