To investigate the association between neutrophil to lymphocyte ratio (NLR) andestimated glomerular filtration rate (eGFR) in patients with diabetes using large-scale data. Across-sectional analysis was conducted using data from diabetic patients in the National Health and Nutrition Examination Survey database from 2009 to 2014. Differences in NLR between patients with and without chronickidney disease (CKD) were compared. Pearson correlation analysis and multiple linear regression models wereapplied to assess the relationship between NLR and eGFR. A total of 857 diabetic patients were included, with 190 (22.2%) having CKD and 667 (77.8%) without CKD. NLR was significantly higher in patients with CKD compared to those without CKD (2.94±1.69 vs.2.36±1.98, NLR is independently negatively associatedwith eGFR in diabetic patients, demonstrating potential clinical value as an indicator of kidney function declineand CKD risk in this population.

AIM: To investigate the abnormal conditions and change patterns of accommodative facility in patients with different refractive states before and after small incision lenticule extraction(SMILE)surgery.METHODS:A prospective clinical cohort study was conducted. A total of 59 patients(118 eyes)who underwent SMILE surgery and had visual function files established in our hospital from June to December 2023 were randomly selected, including 37 males and 22 females, aged 18-35 years(with an average age of 25.19±5.65 years). According to the preoperative spherical equivalent(SE), they were divided into two groups: the low-to-moderate myopia group(SE≥-6.00 DS)with 40 patients(80 eyes), and the high myopia group(SE<-6.00 DS)with 19 patients(38 eyes). The monocular and binocular accommodative facility before surgery and at 1 wk and 1 mo after surgery were compared, and the changes in accommodative facility before and after SMILE surgery in the two groups of patients were analyzed.RESULTS:All surgeries were completed successfully. In the low-to-moderate myopia group, 33 cases(66 eyes)completed the 1-month follow-up after surgery, with a loss to follow-up rate of 17.5%(7/40). In the high myopia group, 15 patients(30 eyes)completed the 1-month follow-up after surgery, with a loss to follow-up rate of 21.1%(4/19). After SMILE surgery, the uncorrected visual acuity and SE of both low-to-moderate myopia and high myopia were significantly improved(all P<0.05). The accommodative facility of the right eyes in all the patients at 1 mo after surgery was better than that before surgery and at 1 wk after surgery(P=0.002, 0.006), the accommodative facility of the left eyes was significantly increased at 1 mo after surgery than that at 1 wk after surgery(P=0.005), and the binocular accommodative facility at 1 mo after surgery was significantly increased compared with that before surgery(P<0.017). Furthermore, there were statistical significance in accommodative facility of the right eyes in the low-to-moderate group at 1 mo compared with that before surgery and at 1 wk after surgery(P=0.011, 0.004); it was significantly increased in the left eyes at 1 mo after surgery compared with that at 1 wk after surgery(P=0.001), and binocular accommodative facility at 1 mo after surgery was significantly better than that before surgery(P<0.001). Furthermore, there was no statistical significance in the right, left and binocular accommodative facility of patients in the high myopia group(all P>0.017).CONCLUSION: After SMILE surgery, the monocular accommodative facility shows a transient decrease and then exceeds the preoperative level at 1 mo after surgery, and the binocular accommodative facility gradually improves after surgery. SMILE surgery has a positive impact on the monocular and binocular accommodative facility in patients with low-to-moderate myopia, but has no significant impact on the accommodative facility in patients with high myopia. It is of clinical significance to strengthen the detection of monocular and binocular accommodative facility before and after SMILE surgery.

Objective To investigate the bone protective effects and underlying mechanisms of 900MHz radiofrequency radiation (RF) at different power densities (50, 150, and 450 μW/cm²) on an ovariectomy-induced osteoporosis mouse model. Methods Sixty 3-month-old C57BL/6 female mice were randomly divided into Sham group (sham exposure), OVX group (ovariectomy), OVX + LRF group (OVX + 50 μW/cm2 RF), OVX + MRF group (OVX + 150 μW/cm2 RF), OVX + HRF group (OVX + 450 μW/cm2 RF), and OVX + E2 group (OVX + estradiol). Ovariectomized mice in the OVX + RF groups were exposed to RF of varying power densities for 4 hours daily. Ovariectomized mice in the OVX + E2 group received intramuscular injections of estradiol (0.04 mg/kg) every two days. After four weeks of intervention, Micro-CT, ELISA, RT-PCR, and immunohistochemistry were employed to analyze bone density, bone microstructure, serum bone metabolic markers, and the expression of related genes and proteins. Results Compared with the Sham group, the OVX group showed significantly decreased bone mineral density (BMD) and bone microstructure indicators such as BV, BV/TV, Tb.Th, and Tb.N, significantly increased bone microstructure indicator Tb.Sp, significantly decreased serum estradiol, significantly increased serum CTX-I, TRACP-5b, BGP, and OPG, significantly increased Nfatc1 and Runx2 mRNAs, and significantly increased OPG and RANKL. Compared with the OVX group, the OVX + MRF group and OVX + E2 group exhibited significantly increased BMD, BV, BV/TV, Tb.Th, and Tb.N, significantly decreased Tb.Sp, significantly increased serum OPG, Runx2 mRNA, and OPG, and significantly decreased serum CTX-I, TRACP-5b, Nfatc1 mRNA, and RANKL. Compared with the OVX group, the OVX + LRF group showed significantly increased cortical bone BMD and Tb.Th, the OVX + HRF group showed significantly increased cortical bone BMD and serum CTX-I and TRACP-5b, and the OVX + MRF group showed significantly increased serum BGP. Among the three power densities, the 150 μW/cm2 RF showed the most significant effect. Conclusion The 150 μw/cm2 900 MHz RF can counteract the abnormalities in serum bone metabolism biomarkers, the decrease in BMD, the degeneration of bone microstructure, and the increase in bone resorption caused by ovariectomy in mice.

ObjectiveTo investigate the effect and molecular mechanism of exosomes derived from bone marrow mesenchymal stem cells(BMSC-exos) modified with Bushen Yisui capsule(BSYS)-containing serum on promoting the differentiation and maturation of OLN-93 oligodendrocytes by regulating miR-15b/Wnt signaling pathway. MethodsOLN-93 cells were divided into 5 groups, including the normal(NC) group, BMSC-exos group, BSYS-BMSC-exos group, BSYS-BMSC+LV-miR-15b-5p inhibitor-exos group, and BSYS-BMSC+LV-miR-15b-5p NC-exos group. DiR staining was used to observe the uptake of Exos by OLN-93 cells. The effective dosage of BSYS-BMSC-exos on OLN-93 cells was assessed by cell proliferation and activity assay(CCK-8). Stable BMSCs lentiviral transfection strains were established to inhibit miR-15b-5p expression in both BMSCs and their exos, and transfection efficiency was verified by real-time fluorescent quantitative polymerase chain reaction(Real-time PCR) detection of miR-15b-5p. The expressions of 2′,3′-cyclic nucleotide 3′-phosphodiesterase(CNPase) and myelin proteolipid protein(PLP) in OLN-93 cells were detected by immunocytochemistry(ICC) and Western blot. The mRNA expressions of miR-15b-5p and Wnt3a in OLN-93 cells were detected by Real-time PCR, and the protein expression of Wnt3a was measured by Western blot. The expression levels of key molecules in the Wnt/β-catenin signaling pathway of OLN-93 cells, including glycogen synthase kinase(GSK)-3β, β-catenin, and T-cell specific transcription factor 4/transcription factor 7-like 2(TCF4/TCF7L2), were measured by Real-time PCR and Western blot. ResultsDiR-labeled Exos were efficiently taken up by OLN-93 cells. The CCK-8 assay results indicated that 20 mg·L-1 of BSYS-BMSC-exos exhibited the most significant effect in enhancing OLN-93 cell viability(P<0.01) and this dosage was selected for subsequent experiments. Following lentiviral transfection of BMSCs, Real-time PCR results revealed that miR-15b-5p was significantly suppressed in BMSCs(P<0.01), and miR-15b-5p was also notably inhibited in BSYS-BMSC-exos(P<0.01). ICC analysis further revealed an increase in the number of differentiated, mature CNPase and PLP-positive cells following BSYS-BMSC-exos treatment(P<0.01). Western blot results demonstrated that the protein expression of CNPase and PLP was significantly enhanced with BSYS-BMSC-exos treatment(P<0.01). Additionally, BSYS-BMSC-exos also increased the expression levels of miR-15b-5p and p-β-catenin proteins in OLN-93 cells, while decreased the mRNA and protein expressions of Wnt3a, as well as the mRNA expressions of β-catenin and TCF4/TCF7L2, and the protein expression level of p-GSK-3β(Ser9) was significantly reduced(P<0.05, P<0.01). After the transfection of miR-15b-5p inhibitor into BSYS-BMSC-exos, the above effects were significantly diminished(P<0.05, P<0.01). ConclusionBSYS-BMSC-exos facilitate the differentiation and maturation of OLN-93 cells, and its mechanism is related to the upregulation of miR-15b-5p in OLN-93 cells, which inhibits the expression of Wnt3a and thereby suppresses the Wnt signaling pathway.

Background::Breast cancer (BC) risk-stratification tools for Asian women that are highly accurate and can provide improved interpretation ability are lacking. We aimed to develop risk-stratification models to predict long- and short-term BC risk among Chinese women and to simultaneously rank potential non-experimental risk factors.Methods::The Breast Cancer Cohort Study in Chinese Women, a large ongoing prospective dynamic cohort study, includes 122,058 women aged 25-70 years old from the eastern part of China. We developed multiple machine-learning risk prediction models using parametric models (penalized logistic regression, bootstrap, and ensemble learning), which were the short-term ensemble penalized logistic regression (EPLR) risk prediction model and the ensemble penalized long-term (EPLT) risk prediction model to estimate BC risk. The models were assessed based on calibration and discrimination, and following this assessment, they were externally validated in new study participants from 2017 to 2020.Results::The AUC values of the short-term EPLR risk prediction model were 0.800 for the internal validation and 0.751 for the external validation set. For the long-term EPLT risk prediction model, the area under the receiver operating characteristic curve was 0.692 and 0.760 in internal and external validations, respectively. The net reclassification improvement index of the EPLT relative to the Gail and the Han Chinese Breast Cancer Prediction Model (HCBCP) models for external validation was 0.193 and 0.233, respectively, indicating that the EPLT model has higher classification accuracy.Conclusions::We developed the EPLR and EPLT models to screen populations with a high risk of developing BC. These can serve as useful tools to aid in risk-stratified screening and BC prevention.

Membranous nephropathy(MN)is the predominant cause of primary nephrotic syn-drome(NS)among adults.The identification of PLA2R as target antigen has brought about a pro-found transformation in the management of MN,offering a basis for the utilization of B-cell deplet-ing agents such as rituximab(RTX).The question of whether early intervention targeting antibodies can effectively impede the progression of MN,contrib-uting to enhanced disease control and long-term renal outcomes for patients,remains further explo-ration.We analyzed demographic data,laboratory parameters,and renal involvement in 13 patients with PLA2R antibody-related MN who received at least one RTX treatment at our center from Octo-ber 2019 to March 2023.Early-stage medium-to-high-risk MN was defined as baseline or admission anti-PLA2R antibody levels exceeding 50 RU/mL,ex-cluding patients who already presented with ne-phrotic syndrome at baseline.The median duration of MN at the initiation of the first RTX treatment was 4.1 months(IQR 1-7.7),and the median follow-up time after RTX therapy was 27 months(IQR 23-45).All patients had commenced renin-angiotensin system inhibitors before receiving RTX.Following RTX therapy,none of the 13 patients progressed to NS during the follow-up period,and 12 patients achieved complete or partial remission at the 2-year follow-up or the last visit.No deaths,severe infections,or other serious adverse reactions oc-curred during the follow-up period.In conclusion,RTX demonstrates favorable efficacy and safety in early-stage,medium-to-high-risk MN patients.Initi-ating antibody clearance therapy in these patients may be beneficial for long-term disease control and distant renal outcomes.

Objective:To evaluate the effect of patient-controlled intravenous analgesia (PCIA) with esketamine mixed with hydromorphone on the postoperative sleep quality in pediatric patients.Methods:This was a prospective randomised controlled study. One hundred pediatric patients of both sexes, aged 4-12 yr, with a body mass index of 13-26 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, undergoing elective abdominal surgery with general anesthesia, who agreed to use postoperative patient-controlled intravenous analgesia in our hospital from January to November 2023, were divided into esktamine mixed with hydromorphone group (EH group) and hydromorphone group (H group), with 50 patients in each group. PCIA solution contained esketamine 1 mg/kg and hydromorphon 0.1 mg/kg in 100 ml of 0.9% sodium chloride in EH group and hydromorphone 0.2 mg/kg in 100 ml of 0.9% sodium chloride in H group. The Pittsburgh Sleep Quality Index was used to evaluate the preoperative sleep quality by asking pediatric patients themselves or their guardians. On the morning of 1-3 days after surgery, the numeric rating scale (NRS) was used to evaluate the sleep quality of the first 3 nights after surgery. At 24 and 48 h after surgery, the FLACC pain scale was used to evaluate the intensity of pain. The consumption of hydromorphone within 48 h after surgery and the incidence of postoperative adverse reactions such as nausea, vomiting, itching and delirium were recorded. Results:Compared with group H, the NRS score was significantly increased on the 1st postoperative night, the ratio of poor sleep quality was decreased ( P<0.05), and no significant change was found in the NRS score on the 2nd or 3rd postoperative night and ratio of poor sleep quality ( P>0.05), and the FLACC pain scale score at 24 and 48 h after surgery and consumption of hydromorphone within 48 h after surgery were decreased in group EH ( P<0.05). There was no significant difference in the incidence of postoperative adverse reactions between the two groups ( P>0.05). Conclusions:PCIA with esketamine mixed with hydromorphone can improve the postoperative sleep quality in pediatric patients.

Objective:To investigate the expression levels of serum KLK5, IL-17 and IL-18 in patients with rosacea and their clinical significance.Methods:A prospective study included 65 patients with rosacea from the Department of Dermatology, Sichuan Provincial People's Hospital, from May to October 2022. There were 8 males and 57 females with an average age of (30.9±9.8) years, including 47 cases of erythematotelangiectatic type and 18 cases of papulopustular type. Twenty healthy individuals from the same hospital's physical examination during the same period were included as control group, consisting of 3 males and 17 females with an average age of (33.8±10.0) years. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression levels of serum KLK5, IL-17, and IL-18. Investigator's global assessment (IGA) score was used to assess the severity of papules and pustules, and clinical erythema assessment (CEA) score was used to assess the severity of persistent erythema. The expression levels of serum KLK5, IL-17, and IL-18 were compared between the two groups, and the correlation between the severity of the disease and the expression levels of KLK5, IL-17, and IL-18 was analyzed. Additionally, the expression levels of KLK5, IL-17, and IL-18 in different subtypes of rosacea were compared.Results:The expression levels of serum KLK5, IL-17, and IL-18 in the rosacea group were (3134.01±448.82), (154.78±37.64), (236.24±38.81) pg/ml, respectively, all of which were higher than those in the healthy control group (2421.54±340.07), (95.36±24.94), (181.61±23.88) pg/ml, with statistically significant differences (all P<0.05). The levels of serum KLK5, IL-17, and IL-18 in patients with rosacea were positively correlated with IGA scores ( r=0.534, 0.767, 0.417) and CEA scores ( r=0.852, 0.459, 0.309) (all P<0.05). There were no statistically significant differences in the expression levels of serum KLK5, IL-17, and IL-18 between the erythematotelangiectatic and papulopustular subtypes of rosacea (all P>0.05). Conclusions:The expression levels of serum KLK5, IL-17 and IL-18 in patients with rosacea are higher than those in the healthy control group and are positively correlated with the severity of rosacea.
