OBJECTIVE: To observe the effect of electroacupuncture combined with enhanced recovery after surgery (ERAS) protocol on promoting intestinal function in patients after gastric cancer surgery. METHODS: Forty-four patients who underwent radical gastrectomy for gastric cancer were randomly divided into an experimental group (22 cases, 3 cases were excluded) and a control group (22 cases, 4 cases were excluded). Both groups received treatment under ERAS protocol, the experimental group was given electroacupuncture at bilateral Neiguan (PC6), Hegu (LI4), Zusanli (ST36) and Quchi (LI11), disperse-dense wave was selected, with frequency of 2 Hz/100 Hz. The control group received placebo electroacupuncture intervention, with the same acupoints as the experimental group, electrode pads were placed on the acupoints without electrical stimulation. Each session lasted 30 min, starting from 1 h after surgery, once every 24 h, until the patient resumed anal flatus. The intestinal sound rate of both groups was observed 24 h before surgery and 24, 48 h after surgery. The bowel sound recovery time (BSRT), time to first anal flatus, time to first defecation, and tolerance to oral enteral nutrition suspension were compared between the two groups. The levels of serum C-reactive protein (CRP), interleukin (IL)-2, IL-4, IL-6, IL-10, IL-12, IL-17, tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) were measured 24 h before surgery and 24 h after surgery in both groups. RESULTS: The intestinal sound rate 24 h after surgery was decreased compared with that 24 h before surgery in the two groups (P<0.05), the intestinal sound rate 24, 48 h after surgery in the experimental group was higher than that in the control group (P<0.05). The BSRT in the experimental group was earlier than that in the control group (P<0.05) .The levels of serum CRP, IL-6, IL-10 24 h after surgery in the experimental group were higher than those 24 h before surgery (P<0.05), while the levels of serum CRP, IL-4, IL-6, IL-10, IFN-γ in the control group were higher than those 24 h before surgery (P<0.05); the levels of serum CRP、IL-4、IFN-γ 24 h after surgery in the experimental group were lower than those in the control group (P<0.05) .The tolerance rate of oral enteral nutrition suspension in the experimental group was 84.2% (16/19), which was higher than 50.0% (9/18) in the control group (P<0.05). CONCLUSION Electroacupuncture combined with ERAS protocol can improve the intestinal motility, shorten the BSRT, enhance the tolerance of oral intake, and reduce inflammatory response in patients after gastric cancer surgery.

Loss-of-function variants of low-density lipoprotein receptor-related protein 5 (LRP5) can lead to reduced bone formation, culminating in diminished bone mass. Our previous study reported transcription factor osterix (SP7)‍-binding sites on the LRP5 promoter and its pivotal role in upregulating LRP5 expression during implant osseointegration. However, the potential role of SP7 in ameliorating LRP5-dependent osteoporosis remained unknown. In this study, we used mice with a conditional knockout (cKO) of LRP5 in mature osteoblasts, which presented decreased osteogenesis. The in vitro experimental results showed that SP7 could promote LRP5 expression, thereby upregulating the osteogenic markers such as alkaline phosphatase (ALP), Runt-related transcription factor 2 (Runx2), and β‍-catenin (P<0.05). For the in vivo experiment, the SP7 overexpression virus was injected into a bone defect model of LRP5 cKO mice, resulting in increased bone mineral density (BMD) (P<0.001) and volumetric density (bone volume (BV)/total volume (TV)) (P<0.001), and decreased trabecular separation (Tb.‍Sp) (P<0.05). These data suggested that SP7 could ameliorate bone defect healing in LRP5 cKO mice. Our study provides new insights into potential therapeutic opportunities for ameliorating LRP5-dependent osteoporosis.

Autoimmune diseases, cancers, and viral infections pose significant global health threats, characterized by chronic pathology, unregulated cellular proliferation, and rapid transmission, respectively, requiring urgent early warning and treatment strategies. Antibodies, primarily classified into autoantibodies and therapeutic antibodies based on their clinical roles, provide essential information and show considerable value in the precise diagnosis and treatment of these serious diseases. Among the technologies utilized in bioanalysis, electrochemical biosensors, with their unique advantages of rapid response, high sensitivity, miniaturization, cost-effectiveness and user-friendly operation, have been developed as a trending technology for precise diagnostic and therapeutic drug monitoring. This review systematically summarizes the relationships and roles of clinically relevant antibodies in autoimmune diseases, cancers, and viral infections, while detailing the composition, strategies, development, and application trends of relevant electrochemical biosensors. Furthermore, it highlights the remaining challenges and opportunities for the advancement and prospects of electrochemical sensors in the context of clinically relevant antibodies.

In order to delve into the molecular mechanism underlying the increased pathogenicity of the recombinant Muscovy duck parvovirus(rMDPV)towards Muscovy ducklings,two sub-genom-ic fragments of the rMDPV strain ZW were cloned into the plasmid pBluescript Ⅱ(SK)to gener-ate the recombinant plasmid pZW.A single nucleotide mutation was engineered in the VP3 gene of pZW to discriminate from the parental strain ZW.pZW plasmid-lipid complex was transfected into the chorioallantoic membrane of 11-day-old embryonated Muscovy duck embryos,resulting in res-cue of infectious virus,rZW,carrying the genetic marker.The rescued virus was passaged in 12-day-old embryonated Muscovy duck embryos and exhibited the similar medium embryo lethal dose(ELD50)value and growth curve compared to the parental strain ZW.Both rZW and strain ZW led to 100％mortality in the infection tests performed with 3-day-old Muscovy duckling.Postmortem necropsy revealed a characteristic intestine embolism formed in the rZW-infected ducklings.Taken together,the generation of the infectious clone pZW lays a solid foundation for deciphering the pathogenesis of rMDPV.

Objective To evaluate the feasibility of early postoperative bathing within the framework of Enhanced recovery after surgery(ERAS)perioperative management.Methods A total of 156 patients who underwent laparoscopic appendectomy or cholecystectomy in the Department of General Surgery between December 2024 and May 2025 were included in the study.Based on the postoperative bathing protocol selected 24 hours after surgery,patients were randomly assigned to one of three groups:the early bathing-exposed group,the early bathing-covered group,or the control group.In the early bathing-exposed group,patients were permitted to bathe with the surgical incision uncovered 24 hours postoperatively.In the early bathing-covered group,sterile,waterproof dressings were applied to the incision site during bathing to maintain aseptic conditions.The control group followed conventional postoperative care guidelines,which restricted bathing until at least three days after suture removal.The outcomes,including the incidence of surgical site infection,postoperative complications,length of hospital stay,and follow-up data,were systematically recorded and analyzed across all three groups.Results Finally,54 patients were included in the early bathing-exposed group,52 in the early bathing-covered group,and 50 in the control group.No statistically significant differences were observed among the three groups in terms of baseline clinical characteristics,including gender,age,primary disease,comorbidities,body mass index(BMI),surgical procedure,operative duration,or incision classification(all P>0.05).Similarly,postoperative comparisons of time to first bathing,incisional infection rates,complication incidence,and length of hospital stay showed no significant intergroup differences(all P>0.05).However,with respect to patient satisfaction during hospitalization,both early bathing groups reported significantly higher satisfaction scores compared to the control group,and these differences were statistically significant(all P<0.05).Conclusions Compared with the conventional principle of postoperative water restriction,early bathing does not increase the incidence of surgical site infection and contributes to improved patient satisfaction during hospitalization.This approach broadens the scope of early postoperative interventions within the ERAS protocol and warrants further clinical implementation.

Objective To investigate the association between serum magnesium levels,serum phosphorus concentrations,vascular calcification,and cardiovascular disease mortality in maintenance hemodialysis patients.Methods This study enrolled 200 hemodialysis patients admitted to Nanjing Drum Tower Hospital from May 2020 to May 2022 as subjects,with an additional 200 healthy individuals from the same period selected as a control group.The biochemical indicators between the two groups were compared;their correlations were analyzed.Binary logistic regression was used to investigate the independent factors of serum magnesium and phosphorus levels in relation to vascular calcification and cardiovascular events in maintenance hemodialysis patients.ROC curve analysis was employed to assess the predictive value of serum magnesium and phosphorus for vascular calcification and cardiovascular events.Results The research group's patients exhibited significantly elevated levels of blood phosphorus,calcium-phosphorus product,iPTH,AACS,and 25-(OH)-VitD compared to the control group.In contrast,their blood magnesium and BMP-7 levels were notably lower than those of the control group,with statistical significance(P<0.05).Pearson correlation showed positive correlations between serum magnesium and serum calcium,phosphorus,calcium-phosphorus product,25-(OH)-VitD3,and BMP-7(r=0.385,0.183,0.141,0.131,0.458,P<0.05);between serum calcium and serum phosphorus,calcium-phosphorus product,iPTH,AACS,25-(OH)-VitD3,and BMP-7(r=0.318),correlation(r=0.318,0.311,0.098,0.170,0.277,0.485,P<0.05);between serum phosphorus and calcium-phosphorus product,iPTH,AACS,25-(OH)-VitD3(r=0.362,0.506,0.367,0.461,P<0.05);between calcium-phosphorus product and iPTH,AACS,25-(OH)-VitD3(r=0.542,0.373,0.434,P<0.05);between iPTH and AACS,25-(OH)-VitD3 showing positive correlations(r=0.553,0.616,P<0.05)and a negative correlation with BMP-7(r=-0.373,P<0.05);between AACS and 25-(OH)-VitD3 showing a positive correlation(r=0.402,P<0.05),and a negative correlation with BMP-7(r=-0.155,P<0.05),with statistically significant differences(P<0.05).Statistically significant differences were noted between the two groups in age,diabetes,serum magnesium,serum calcium,serum phosphorus,calcium-phosphorus product,25-(OH)-VitD3,and hs-CRP(P<0.05).Logistic regression analysis showed that age,serum magnesium,serum calcium,serum phosphorus,calcium phosphate product,25-(OH)-vitamin I were all risk factors for cardiovascular disease(CVD)mortality in maintenance hemodialysis(MHD)patients(P<0.05).ROC curve analysis showed that serum magnesium,serum calcium,and serum phosphorus had predictive areas under the curve(AUC)of 0.895,0.802,and 0.851 for CVD mortality in MHD patients,with sensitivities and specificities of 87.5%/98.7%,66.7%/90.8%,and 72.9%/100%,respectively.The combined prediction for CVD mortality in MHD patients showed an AUC of 0.921,with a sensitivity of 81.3%and specificity of 93.4%.Conclusion MHD patients exhibit low blood magnesium levels,elevated serum phosphorus concentrations,and increased calcium-phosphorus product,with complex correlations among these biomarkers.Age,magnesium,calcium,and phosphorus levels were all associated with CVD mortality.ROC curve analysis demonstrates that magnesium,calcium,and phosphorus,both individually and in combination,have high predictive value for CVD mortality risk.

Objective To examine the role and mechanism of clopidogrel in the development of salt-sensitive hypertension.Methods 8-week-old Dahl salt-sensitive(Dahl SS)rats and control salt-resistant(SS13BN)rats were divided randomly into six groups and fed for 8 weeks with normal salt(0.4％NaCl,NS),high salt(8％NaCl,HS),or high salt combined with clopidogrel gavage(8％NaCl+10 mg/(kg·d))clopidogrel,HS+CLO).Arterial systolic blood pressure was measured continuously over 8 weeks by the tail-cuff method,and systolic blood pressure was measured by carotid cannulation after 8 weeks(56 days).Renal histopathology was observed by hematoxylin and eosin staining,and renal inflammatory cell infiltration was detected by immunohistochemistry.Peripheral blood platelet activation and platelet-leukocyte aggregation were analyzed by flow cytometry,and the renal inflammation-related proteins tumor necrosis factor-α,interleukin(IL)-1β,IL-6,and key proteins in the p38MAPK/nuclear factor(NF)-κB signaling pathway were detected by Western blot.Results Compared with the NS group,Dahl SS HS rats had significantly increased blood pressure(P＜0.05),aggravated renal tissue damage,increased inflammatory cell infiltration,increased expression of inflammatory cytokines(P＜0.05),elevated peripheral blood platelet activation(P＜0.05)and platelet-leukocyte aggregation(P＜0.05),and increased expression of p38MAPK/NF-κB signaling pathway proteins(P＜0.05).Clopidogrel effectively alleviated these phenotypes induced by high salt in Dahl SS rats.Conclusions Clopidogrel alleviated high-salt-induced salt-sensitive hypertension and decreased renal inflammatory responses and dysfunction in Dahl SS rats by inhibiting platelet activation and the p38MAPK/NF-κB signaling pathway.
