This study aimed to explore the therapeutic mechanisms of Colquhounia Root Tablets(CRT) in treating diabetic kidney disease(DKD) by integrating biomolecular network mining with animal model verification. By analyzing clinical transcriptomics data, an interaction network was constructed between candidate targets of CRT and DKD-related genes. Based on the topological eigenvalues of network nodes, 101 core network targets of CRT against DKD were identified. These targets were found to be closely related to multiple pathways associated with type 2 diabetes, immune response, and metabolic reprogramming. Given that immune-inflammatory imbalance driven by metabolic reprogramming is one of the key pathogenic mechanisms of DKD, and that many core network targets of CRT are involved in this pathological process, receptor for advanced glycation end products(RAGE)-reactive oxygen species(ROS)-phosphatidylinositol 3-kinase(PI3K)-protein kinase B(AKT)-nuclear factor-κB(NF-κB)-NOD-like receptor family pyrin domain containing 3(NLRP3) signaling axis was selected as a candidate target for in-depth research. Further, a rat model of DKD induced by a high-sugar, high-fat diet and streptozotocin was established to evaluate the pharmacological effects of CRT and verify the expression of related targets. The experimental results showed that CRT could effectively correct metabolic disturbances in DKD, restore immune-inflammatory balance, and improve renal function and its pathological changes by inhibiting the activation of the RAGE-ROS-PI3K-AKT-NF-κB-NLRP3 signaling axis. In conclusion, this study reveals that CRT alleviates the progression of DKD through dual regulation of metabolic reprogramming and immune-inflammatory responses, providing strong experimental evidence for its clinical application in DKD.

This study primarily investigates the effect of Liuwei Dihuang Pills on the activation and proliferation of female germline stem cells(FGSCs) in the ovaries and cortex of mice with premature ovarian failure(POF), and how it improves ovarian function. ICR mice were randomly divided into the control group, model group, Liuwei Dihuang Pills group, Liuwei Dihuang Pills double-dose group, and estradiol valerate group. A mouse model of POF was established by intraperitoneal injection of cyclophosphamide. After successful modeling, the mice were treated with Liuwei Dihuang Pills or estradiol valerate for 28 days. Vaginal smears were prepared to observe the estrous cycle and body weight. After the last administration, mice were sacrificed and sampled. Serum levels of estradiol(E_2), follicle-stimulating hormone(FSH), luteinizing hormone(LH), and anti-Müllerian hormone(AMH) were measured by enzyme-linked immunosorbent assay(ELISA). Hematoxylin-eosin(HE) staining was used to observe ovarian morphology and to count follicles at all stages to evaluate ovarian function. Immunohistochemistry was used to detect the expression of mouse vasa homolog(MVH), a marker of ovarian FGSCs. Immunofluorescence staining, using co-labeling of MVH and proliferating cell nuclear antigen(PCNA), was used to detect the expression and localization of specific markers of FGSCs. Western blot was employed to assess the protein expression of MVH, octamer-binding transcription factor 4(Oct4), and PCNA in the ovaries. The results showed that compared with the control group, the model group exhibited disordered estrous cycles, decreased ovarian index, increased atretic follicles, and a reduced number of follicles at all stages. FSH and LH levels were significantly elevated, while AMH and E_2 levels were significantly reduced, indicating the success of the model. After treatment with Liuwei Dihuang Pills or estradiol valerate, hormone levels improved, the number of atretic follicles decreased, and the number of follicles at all stages increased. MVH marker protein and PCNA proliferative protein expression in ovarian tissue also increased. These results suggest that Liuwei Dihuang Pills regulate estrous cycles and hormone disorders in POF mice, promote the proliferation of FGSCs, improve follicular development in POF mice, and enhance ovarian function.

OBJECTIVES: To study the clinical characteristics of pediatric Behçet syndrome (BS). METHODS: A retrospective review was conducted on the medical records of children hospitalized in the Department of Pediatrics at the Second Hospital of Hebei Medical University between December 2014 and December 2024 who met diagnostic criteria for BS. RESULTS: Among 45 children with BS, 26 (58%) were male. Oral aphthous ulcers were the most common manifestation (43/45, 96%), followed by genital ulcers (23/45, 51%) and gastrointestinal involvement (18/45, 40%). Genital ulcers were more frequent in girls, whereas ocular involvement was more common in boys (P<0.05). The pathergy test was positive in 10 (22%), and HLA-B51 was positive in 13 (29%). Fecal calprotectin (FC) was elevated in 16 (36%); gastrointestinal involvement was more frequent in children with elevated FC than in those with normal FC (P<0.05). According to the respective criteria, 17 (38%) patients met the International Study Group criteria (1990), 33 (73%) met the International Criteria for Behçet Disease (2014), and 13 (29%) met the Pediatric Behçet Disease criteria (2015). CONCLUSIONS Pediatric BS shows marked clinical heterogeneity. HLA-B51 is associated with disease susceptibility.

Objective This study aimed to comprehensively survey the tick distribution in the natural scenic belts of various counties and districts in Huai'an City, Jiangsu Province, and to provide guidance on tick control measures. Methods From 2023 to 2024, questing ticks in 29 natural scenic belts spanning seven counties and districts of Huai'an City were collected using hand-scratching method. Further, parasitic ticks in the surrounding areas were collected using the animal search method. Collected ticks were subsequently identified to the species level in the laboratory. Results In total, 288 questing ticks were collected, all belonging to the genus Haemaphysalis of family Ixodidae. Hae. longicornis was the dominant species, accounting for 98.61%, followed by Hae. flava(1.04%)and Hae. phasiana(0.35%). The average tick density index in Lotus Lake Scenic Area(Jinhu County), All-People Fitness Theme Park(Lianshui County), Peach Blossom Valley(Qingjiangpu District), Huai'an Forest Park(Huai'an District), Qizu of Gaozhuang Village(Hongze District), Ancient Yellow River Sports Park(Huaiyin District), Putao Trench and(Xuyi County)was 0.022, 0.025, 0.01, 0.10,0.22,0.28, and 0.79 ticks/flag·100 m, respectively. In total,114 parasitic ticks were collected at the monitoring sites, with an average tick infestation rate of 69.25% in sheep and 100% in dogs at Tianquanhu Town in Xuyi County; all of these were Hae. longicornis. All parasitic ticks were from Xuyi County, and no parasitic ticks were found at the monitoring sites in Huai'an District, Hongze District, and Lianshui County. Conclusions Overall, with the advancement of eco-tourism resorts and urban greening construction in Huai'an City, the presence of ticks was confirmed by this study in previously unsurveyed areas. As the frequency of human-animal interactions increases in these areas, the potential risk of tick-borne diseases also rises. Furthermore, this study provides important clues for subsequent investigations into local tick-borne pathogens.

Objective To study the effect of drinking carbohydrate drinks before cesarean section on mothers and neonates,and to explore the application value of drinking carbohydrate drinks before cesarean section.Methods The clinical data of 206 singleton women who underwent selective cesarean section in Obstetrics and Gynecology Hospital,Fudan University from Jun 2020 to Jun 2021 were retrospectively studied.Patients were divided into enhanced recovery after delivery(ERAD)group and control group according to whether drinking carbohydrate drinks before cesarean section.A retrospective cohort study was conducted to analyze the effect of preoperative carb drinks on preoperative fluid supplementation,postoperative rehabilitation and neonatal prognosis.Results Among patients who fasted for less than 12 hours,the ERAD group had a lower fluid supplementation rate and a smaller average fluid supplementation volume compared to the control group(P＜0.05).The ERAD group had a lower rate of prokinetic agent using after surgery(P＜0.05).Among women without a history of abdominal surgery,the ERAD group had less blood loss 24 hours after surgery(P＜0.05).There were no significant differences in postoperative fever rate,incidence of nausea and vomiting,time of first flatus,neonatal apgar score,exit observation room neonatal blood,and neonatal neonatal intensive care unit(NICU)admission rate between the two groups.Among newborns with high-risk factors for hypoglycemia,the ERAD group had lower enter observation room neonatal blood compared to the control group,and a higher incidence of hypoglycemia(P＜0.05).Conclusion Oral intake of carbohydrate drinks before cesarean section may be beneficial in reducing fluid supplementation before elective cesarean section,promoting postoperative gastrointestinal function recovery,and reducing postoperative bleeding.However,it may be related to the occurrence of neonatal hypoglycemia.

Objective To analyze the influencing factors for intestinal colonization and secondary infection of car-bapenem-resistant Klebsiella pneumoniae(CRKP)in neonates,and provide a basis for formulating prevention and control strategies for CRKP infection.Methods Neonates who were admitted to the neonatal ward of a hospital from January 2021 to October 2022 were selected as the study subjects,and the first screening of CRKP was con-ducted within 48 hours after admission.In addition,active anal swab screening for carbapenem-resistant Ente-robacterales(CRE)was performed weekly during hospitalization,and the infection status of CRKP strains was mo-nitored.Clinical data of neonates in the colonization group,non-colonization group,and infection group were ana-lyzed.Intestinal colonized strains and the non-repetitive CRKP strains isolated from clinical specimens of neonates with secondary infection after colonization were performed carbapenemase gene detection,multilocus sequence ty-ping(MLST)and pulsed-field gel electrophoresis(PFGE)analysis.Results A total of 1 438 neonates were active-ly screened for CRE,174 were CRKP positive,CRKP colonization rate was 12.1％.Among 174 neonates,35 were with secondary infection,with the incidence of 20.1％.The independent risk factors for neonatal CRKP intestinal colonization were cesarean section(OR=2.050,95％CI:1.200-3.504,P=0.009),use of cephalosporins(OR=1.889,95％CI:1.086-3.288,P=0.024),nasogastric tube feeding(OR=2.317,95％CI:1.155-4.647,P=0.018).Protective factors were breast-feeding(OR=0.506,95％CI:0.284-0.901,P=0.021),oral probiotics(OR=0.307,95％CI:0.147-0.643,P=0.002),and enema(OR=0.334,95％CI:0.171-0.656,P=0.001).Independent risk factors for secondary infection after intestinal colonization of neonatal CRKP were carbapenem anti-biotic use(OR=19.869,95％CI:1.778-222.029,P=0.015)and prolonged hospital stay(OR=1.118,95％CI:1.082-1.157,P＜0.001).The detection results of drug resistance genes showed that carbapenemase-producing genes of CRKP strains were all blaKPC-2,all belonged to type ST11.Homologous analysis showed that intestinal CRKP colonization was highly homologous with the secondary infection strains after colonization.Conclusion CRKP intestinal colonization during neonatal hospitalization may increase the risk of CRKP infection.Risk and pro-tective factors of neonatal intestinal colonization and secondary infections after colonization should be paid attention,and corresponding preventive and control measures should be taken,so as to reduce the occurrence and transmission CRKP healthcare-associated infection.

The purpose of this study was to understand the prevalence of Neoehrlichia mikurensis in rodents in Yunnan commensal rodent plague foci.Lianghe Country,Mangshi City,and Mile City in Yunnan Province were chosen as sampling sites,where rodents were captured with dead-traps.The N.mikurensis groEL gene in rodent spleen samples was detected with nested PCR,and the positive products were sequenced with Sanger bidirectional assays.The infection rate of N.mikurensis a-mong plague foci,habitats,species,and sexes was compared with Chi-square tests or Fisher's exact probability method.Of 656 rodent spleen samples,12 N.mikurensis positive samples were detected in R.tanezumi,R.sladeni,N.confucianus,and B.bowersi.The positivity rate was 1.83％.No significant difference in the N.mikurensis positivity rate was observed a-mong plague foci,habitats,species,and sexes(P＞0.05).Genetic evolution analysis of the groEL gene indicated that the se-quence similarity of nucleic acid sequences in 12 positive samples was 99.5％-100％,and the nucleic acid sequences of N.mikurensis were in the same branch,belonging to cluster Ⅳ.Thus,four species of rodents were found to have low frequency infection with N.mikurensis in Yunnan commensal rodent plague foci.

Objective To investigate the occurrence of posterior femoral head tilt after clinical non-displaced femoral neck fracture,and to provide a reference basis for clinical surgery and improvement of disease prognosis.Methods Total of 165 pa-tients with non-displaced femoral neck fractures of Garden type Ⅰ and Ⅱ from January 2018 to June 2022 were selected as study subjects including 48 males and 117 females,with an average age of(71.5±8.5)years old ranging from 53 to 89,involving 97 cases of type Ⅰ and 68 of type Ⅱ.On the patient's preoperative sagittal or axial CT film of the hip,the angle formed by the ra-dius line of the femoral head and the midline of the femoral neck was used as the posterior tilt angle of the femoral head(α),and the posterior tilt femoral head angle was measured using the method proposed by Palm.The measured data were divided into 6 groups:α＜0°,0°＜α＜5°,5°≤α＜10°,10°≤α＜15°,15°≤α＜20°,α≥20°,and the incidence of different ranges of poste-rior tilt angle was compared.The sex composition ratio of 165 patients were analyzed and compared,and the age of 65 was used as the cut-off point to compare the incidence of fractures between genders.Patients were divided into the posterior tilt＜20° group for 135 cases and the posterior tilt ≥20°group for 30 cases according to the preoperative posterior tilt angle,the differ-ences between two groups in terms of gender and age were analyzed.Results Among 165 patients with non-displaced femoral neck fractures,143 cases with poaterior tilt of the femoral head occurred with an incidence of 86.7％.Posterior tilt 0°＜α＜5° ac-counted for 36 cases with an incidence of 21.8％;5°≤α＜10° accounted for 40 cases with an incidence of 24.2％;10°≤α＜15° accounted for 27 cases with an incidence of 16.4％;15°≤α＜20° accounted for 10 cases with an incidence of 6.1％;posterior tilt angle α≥20° accounted for 30 cases,the incidence was 18.2％,of which the maximum posterior tilt angle was 42.7°.Statis-tical analysis showed that the percentage of fractures in the 165 patients selected for this study was significantly higher in fe-male than in male,and that the female group was more likely to have fractures before the age of 65 years compared to the male group.However,gender,age and fracture subtypes(Garden Ⅰ,Ⅱ)were not influential factors for femoral neck fractures with a preoperative posterior femoral head tilt angle＞20°(P＞0.05).Conclusion The incidence of femoral head posterior tile in non-displaced femoral neck fractures is relatively high,in which severe posterior tile occurs,and the femoral head posterior tile an-gle ≥20° can reach 18.2％.In patients with closed reduction internal fixation,the fracture end needs to be repositioned as much as possible to reduce the risk of postoperative avascular necrosis of the femoral head.In order to prevent femoral neck frac-tures,special attention should be paid to anti-osteoporosis treatment for female.Preoperative assessment of posterior tilt is criti-cal for patients of different ages,genders and fracture subtypes(Garden Ⅰ,Ⅱ).
