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.

OBJECTIVE To establish the HPLC fingerprint of Xintong granules and the quantitative analysis of multi- components by single-marker method (QAMS) to determine the contents of 7 components, so as to provide a scientific basis for their quality control. METHODS HPLC method was used to establish the fingerprints for 10 batches of Xintong granules (No. S1- S10), and similarity evaluation, cluster analysis (CA) and partial least squares-discriminant analysis (PLS-DA) were performed. At the same time, the contents of seven components, including puerarin, daidzin, calycosin-7-O- β -D-glucoside, stilbene glycoside, naringin, icariin and tanshinone ⅡA, were determined by QAMS method, and were compared with the results of external standard method. RESULTS A total of 18 common peaks were marked and 7 peaks were identified in the HPLC fingerprints for 10 batches of Xintong granules, namely puerarin (peak 4), daidzin (peak 7), calycosin-7-O-β-D-glucoside (peak 9), stilbene glycoside (peak 10), naringin (peak 12), icariin (peak 17), and tanshinone ⅡA (peak 18); the similarities among them were more than 0.990, and CA and PLS-DA results showed that S4-S5,S8-S10,S1-S3 and S6-S7 were clustered into three categories, respectively. Using naringin as the internal standard, the contents of puerarin, daidzin, calycosin-7-O-β-D-glucoside, stilbene glycoside, icariin and tanshinone ⅡA were determined to be 7.868 1-10.181 2, 1.709 2-2.374 1, 0.285 2-0.326 3, 1.024 1- 1.523 9, 0.140 2-0.290 4, and 0.077 1-0.219 4 mg/g, respectively, by the QAMS. These results showed no significant differences compared to those obtained by the external standard method. CONCLUSIONS Established HPLC fingerprint and QAMS method are convenient, stable and accurate, which can provide a basis for the quality evaluation of Xintong granules.

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 investigate the efficacy of color Doppler ultrasound-guided percutaneous nephrostomy in the treatment of anastomotic leakage after laparoscopic pyeloplasty.Methods:A retrospective analysis was performed for the data of 15 children with peritoneal irritation after LP who were admitted to the First Affiliated Hospital of Zhengzhou University from January 2018 to January 2023, of which 10 cases were anastomotic leaks and 5 cases were with renal pelvic blood clots. There were 12 males and 3 females. Age (4.2±2.7) years. The lesions were located on the left side of 11 cases and on the right side of 4 cases. All 15 cases had varying degrees of nausea, vomiting, abdominal pain and other symptoms. Physical examination: the children all showed painful faces and tense abdominal muscles. 15 patients had a preoperative pain score of 9.5 (8, 10). Ultrasound examination showed that the anterior and posterior diameters of renal pelvis separation were (34.93±4.86) mm, the anterior and posterior diameter/renal parenchymal thickness of renal pelvis separation was 15.66±1.02, renal dynamic nuclear imaging shows the renal function of the affected side was (29.69±1.71)%. Thirteen cases had the above symptoms before the abdominal drainage tube was removed, and the time of symptom onset was (3.3±1.1) days after surgery, of which 8 cases had a large increase in abdominal drainage, and color Doppler ultrasonography showed a large amount of fluid in the intra-abdominal intestinal space (about 500 ml). In 5 cases, the intraperitoneal drainage volume did not increase, and color Doppler ultrasonography showed strong echo in the renal pelvis, and blood clots were considered. All 13 patients were placed in the prone position under local anesthesia and underwent color Doppler ultrasound-guided percutaneous nephrostomy. The remaining 2 cases had abdominal drainage tube removed on the 3rd day after surgery, and peritoneal irritation signs appeared on the 4th and 6th days after surgery, respectively. Color Doppler ultrasonography showed that there was a large amount of fluid in the intra-abdominal intestinal space, and color Doppler ultrasound-guided peritoneal puncture and drainage + prone percutaneous nephrostomy was performed in the supine position under local anesthesia, and the biochemical analysis of the peritoneal puncture drainage fluid was confirmed to be anastomotic urine leakage. The drainage volume and urine output of 15 cases of peritoneal puncture drainage and pyelostomy were recorded, and the relief of nausea and vomiting symptoms and the score of postoperative pain after percutaneous nephrostomy were recorded. The changes of hydronephrosis and renal function before and after percutaneous nephrostomy were compared.Results:In this study, 15 patients underwent percutaneous nephrostomy with a duration of (16.8±1.9) min. The symptoms of nausea and vomiting disappeared after operation, and the pain scores were 3.2(2, 4) and 0.4(0, 2) at 2 h and 12 h after operation, respectively, which were statistically significant compared with those before operation ( P<0.01). In 13 children with simple percutaneous nephrostomy, the abdominal drainage tube was removed on (3.6±0.8) days and (8.6±1.0) days after percutaneous nephrostomy. In 2 children with peritoneal puncture and drainage plus percutaneous nephrostomy, the abdominal drainage tube was removed 3 days after the fistula operation, and the pyelostomy tube was removed 8 days after the fistula operation. The anterior and posterior diameters of renal pelvis separation were (10.87±4.05), (10.13±3.50) and (9.13±3.11) mm by color Doppler ultrasound at 3, 6 and 12 months after LP operation, respectively, and there were statistically significant differences compared with preoperative comparisons ( P<0.01).The diameter before and after renal pelvis separation was (7.60±2.86) mm, the diameter before and after renal pelvic separation/renal parenchymal thickness was 1.97±0.22, and the renal function was (39.23±2.66)% at 24 months after operation, which was statistically significant compared with that before operation ( P<0.01). Conclusions:Color Doppler ultrasound-guided percutaneous nephrostomy can effectively alleviate symptoms in the early stage, which could help to the healing of ureteral anastomosis, and has less trauma and short operation course.

Levetiracetam (LEV) is the second generation of broad-spectrum anti-epileptic drug. LEV has the advantages of rapid absorption, short half-life, precise efficacy, good tolerance and few drug interactions. In order to improve the clinical efficacy of LEV, and reduce the occurrence of adverse reactions, children, pregnant women, the elderly, and patients with renal insufficiency should receive therapeutic drug monitoring (TDM). Clinically, the samples are usually plasma or serum, and the TDM methods are mostly immunoassay or chromatography. There is currently no consensus on the effective concentration range of LEV, and the correlation between plasma concentration and adverse reactions is also unclear. The main factors affecting LEV plasma concentration include age, pregnancy, and patient compliance. How to interpret TDM results and adjust dosage based on the results will be the focus of future work.

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.
