Background: Both sodium-glucose cotransporters (SGLTs) and Na+/H+ exchangers (NHEs) rely on a favorable Na-electrochemical gradient. Gastrin, through the cholecystokinin B receptor (CCKBR), can induce natriuresis and diuresis by inhibiting renal NHEs activity. The present study aims to unveil the role of renal CCKBR in diabetes through SGLT2-mediated glucose reabsorption. Methods: Renal tubule-specific Cckbr-knockout (CckbrCKO) mice and wild-type (WT) mice were utilized to investigate the effect of renal CCKBR on SGLT2 and systemic glucose homeostasis under normal diet, high-fat diet (HFD), and HFD with a subsequent injection of a low dose of streptozotocin. The regulation of SGLT2 expression by gastrin/CCKBR and the underlying mechanism was explored using human kidney (HK)-2 cells. Results: CCKBR was downregulated in kidneys of diabetic mice. Compared with WT mice, CckbrCKO mice exhibited a greater susceptibility to obesity and diabetes when subjected to HFD. In vitro experiments using HK-2 cells revealed an upregulation of glucose transporters after incubation with high glucose, a response that was significantly attenuated following gastrin intervention. The glucose uptake from the culture medium of cells was altered accordingly. Moreover, gastrin administration effectively mitigated hyperglycemia in WT diabetic mice by inhibition of SGLT2 mediated glucose reabsorption, but this effect was compromised in the absence of CCKBR, as seen in CckbrCKO mice. Mechanistically, gastrin/CCKBR substantially reduced SGLT2 expression in HK-2 cells exposed to high glucose, via modulating Erkuclear factor-kappa B (NF-κB) pathway. Conclusion Our study underscores the crucial role of renal gastrin/CCKBR in SGLT2 regulation and glucose reabsorption, and renal gastrin/CCKBR can be a promising therapeutic target for diabetes.

ObjectiveTo investigate the analgesic effect of Tuina at the "Weizhong （BL 40）" on neuropathic pain in a rat model of chronic constriction injury （CCI） of the sciatic nerve and its potential central spinal mechanisms. MethodsThirty-two Sprague-Dawley rats were randomly divided into four groups （8 rats in each group）， sham-operated group， model group， Tuina group， and blockade group. The CCI model was established in the model group， Tuina group， and the blockade group by ligating the sciatic nerve with catgut， while the sham-operated group underwent only sciatic nerve exposure without ligation. From postoperative day 4 to day 14， rats in the Tuina group and the blockade group received Tuina manipulation at the "Weizhong （BL 40）" using a dynamic pressure distribution measurement system （5 N pressure， 2 Hz frequency， 10 min per session， once daily）. The blockade group also received intraperitoneal injections of the microglial inhibitor minocycline （10 mg/kg） once daily. The sham-operated and the model group underwent the same handling and fixation as the Tuina group without actual Tuina. Mechanical withdrawal threshold （MWT） and paw withdrawal latency （PWL） were measured before surgery and on day 3， 7， 10， and 14 post-surgery. Transmission electron microscopy was used to evaluate sciatic nerve injury and repair， measuring axon diameter and total myelinated fiber diameter to calculate the g-ratio. Western Blotting was performed to detect the protein levels of ionized calcium-binding adapter molecule 1 （Iba-1）， CD206， CD68， interleukin-10 （IL-10）， and β-endorphin （β-EP） precursor pro-opiomelanocortin （POMC） in the ipsilateral spinal dorsal horn. ResultsCompared with the sham-operated group， the model group showed significantly reduced MWT and PWL on day 3， 7， 10， and 14 （P＜0.01）. Compared with the model group， the Tuina group and the blockade group showed increased MWT and PWL on day 10 and 14 （P＜0.05）. Compared with the Tuina group， the blockade group exhibited higher MWT on day 7， 10， and 14， and higher PWL on day 10 （P＜0.05）. Sciatic nerve pathological morphology revealed intact and well-structured myelin in the sham-operated group， while the model group exhibited myelin collapse， distortion， and myelin ovoid formation. The Tuina group displayed partially irregular myelin with occasional myelin collapse， whereas the blockade group exhibited partial myelin irregularities and phospholipid shedding. Compared with the sham-operated group， the model group showed a decreased g-ratio and increased levels of Iba-1 and CD68 in the spinal dorsal horn （P＜0.05 or P＜0.01）. Compared with the model group， the Tuina group and the blockade group exhibited an increased g-ratio and reduced Iba-1 and CD68 levels. Additionally， the Tuina group showed elevated levels of CD206， IL-10， and POMC， whereas the blockade group had decreased CD206 levels （P＜0.05）. ConclusionTuina at "Weizhong （BL 40）" alleviates neuropathic pain in CCI rats， potentially by regulating microglial activation in the spinal cord， inhibiting M1 polarization while promoting M2 polarization， and activating the IL-10/β-EP pathway to exert analgesic effects.

Objective:To investigate the iodine nutrition status of children aged 8 to 10 in Hefei City, Anhui Province, and to provide a theoretical basis for scientific supplementation of iodine for children.Methods:Using multi-stage stratified cluster random sampling method, from 2020 to 2023, in 9 counties (cities and districts) of Hefei City, each counties (cities and districts) were divided into 5 sampling areas according to east, west, south, north and center each year, with one township (street) selected from each area, and one primary school was selected from each township (street), forty non-boarding students aged 8 to 10 years old (half male and half female, with balanced age distribution) were selected from each primary school. Household edible salt samples and one random urine sample were collected for iodine level testing. B-ultrasound method was used to examine the thyroid of children and goiter rate was calculated.Results:A total of 7 200 children's household edible salt were tested, the salt iodine level [ M( Q1, Q3)] was 22.6 (20.6, 24.5) mg/kg, the coverage rate of iodized salt was 98.0% (7 057/7 200), the qualified rate of iodized salt was 96.1% (6 784/7 057), and the qualified iodized salt consumption rate was 94.2% (6 784/7 200). The qualified iodized salt consumption rate was 87.7% (1 578/1 800) in 2023, which did not meet the standard for eliminating iodine deficiency disorders. A total of 7 200 urine samples were tested, the urinary iodine level was 236.0 (161.0, 327.0) μg/L. There were statistically significant differences in the urinary iodine levels among children from different years ( H = 57.96, P < 0.001), ages ( H = 10.01, P = 0.007), and gender ( Z = - 9.01, P < 0.001). A total of 7 200 children were tested for goiter, of which 135 had goiter, with a goiter rate of 1.9%. Conclusions:From 2020 to 2023, the iodine nutrition of children aged 8 - 10 years in Hefei City is generally at an appropriate level. The urinary iodine and goiter rate of children have reached the standard for eliminating iodine deficiency disorders, but the qualified iodized salt consumption rate has not reached the standard for eliminating iodine deficiency disorders, which should be highly valued.

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.
