Objective To explore the correlation between osteocalcin (OCN) and visceral fat area (VFA) in overweight/obese population. Methods The data of 297 overweight/obese people who underwent health examinations in Health Management Department of Second Affiliated Hospital of Xi'an Jiaotong University from August 2021 to August 2024 were analyzed. According to the VFA value measured by InBody, the subjects were divided into an excessive group (VFA ≥100 cm²) and a normal group (VFA<100 cm2). The baseline data, glucose metabolism indicators, lipid metabolism indicators and OCN were compared between the two groups. Binary logistic regression analysis was used to analyze the independent risk factors affecting visceral fat deposition in overweight/obese people. Results According to the VFA value, there were 193 cases (64.98%) in the excessive group and 104 cases (35.02%) in the normal group. There were no statistical differences in gender, age and comorbidities between the two groups (P>0.05). The BMI, FPG, HbA1c, TC, TG, and LDL-C in the excessive group were higher than those in the normal group, while the HDL-C and OCN were lower than those in the normal group (P<0.05). Binary logistic regression analysis revealed that BMI, FPG, HbA1c, TC, TG and LDL-C were independent risk factors for visceral fat deposition in overweight/obese people, while HDL-C and OCN were protective factors (P<0.05). Conclusion Visceral fat deposition in overweight/obese people is closely related to OCN content, and is affected by abnormal glucolipid metabolism, which provides new ideas for the prevention and treatment of obesity-related diseases.

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.

Objective To investigate the mechanism underlying the effect of intra-articular injection of ozonated water on cartilage repair in knee osteoarthritis(KOA)rats via the miR-214-3p/nuclear factor(NF)-κB signaling pathway,to provide a theoretical basis for the clinical application of ozonated water.Methods Sixty male Sprague-Dawley rats were divided randomly into ozonated and experimental groups.Rats in the experimental group were further divided randomly into model,ozonated water,ozonated water+AAV-NC,and adeno-associated virus with ozonated water+AAV-miR-214-3p inhibitor groups.The articular cartilage repair status was evaluated after the respective treatments,using articular cartilage surface gross scoring,hematoxylin/eosin staining,and modified Mankin's score.Expression levels of interleukin(IL)-1β,tumor necrosis factor(TNF)-α,and matrix metalloproteinase(MMP)-13 were detected by enzyme-linked immunosorbent assay(ELISA).Protein expression levels of IκB kinase(IKK)β,p65,and phospho(p)-IκBα were detected in cartilage tissues by Western blot,and gene expression levels of IKKβ,p65,IκBα,and miR-214-3p were detected by real-time polymerase chain reaction(RT-PCR).Results Rats in all groups showed different degrees of cartilage damage compared with the control group,and the scores were significantly lower in the ozonated water and ozonated water+AAV-NC groups compared with the ozonated water+AAV-miR-214-3p inhibitor group(P＜0.05).IL-1β,TNF-α,and MMP-13 levels detected by ELISA were significantly lower in cartilage tissues from rats in the ozonated water and ozonated water+AAV-NC groups compared with the model and ozonated water+AAV-miR-214-3p inhibitor groups(P＜0.05).According to RT-PCR,IKKβ and p65 mRNA levels were significantly down-regulated while IκBα mRNA was significantly up-regulated in cartilage tissues from rats in the ozonated water and ozonated water+AAV-NC groups compared with the model and ozonated water+AAV-miR-214-3p inhibitor groups(P＜0.05).Similarly,IKKβ,p65,and p-IκBα protein expression levels detected by Western blot were significantly down-regulated while IκBα protein expression levels were up-regulated in cartilage tissues from rats in the ozonated water and ozonated water+AAV-NC groups compared with the model and ozonated water+AAV-miR-214-3p inhibitor groups(P＜0.05).Conclusions Ozone hydrotherapy significantly ameliorated cartilage damage in KOA rats,possibly via inhibiting activation of the NF-κB signaling pathway through up-regulation of miR-214-3p expression and promoting cartilage repair in KOA rats.

Magnetic particle testing, as an efficient non-destructive testing method, has been widely applied in the field of defect detection for precision components. This study reports a case of occupational ultraviolet cataract caused by prolonged exposure of a magnetic particle testing worker to ultraviolet radiation exceeding standard intensity levels. Insufficient awareness of the potential ocular damage caused by long-wave ultraviolet radiation, inadequate provision of protective goggles, and non-compliant occupational hygiene monitoring and health examinations were identified as the primary contributing factors to this case.

Objective:To observe the clinical efficacy of unilateral biportal endoscopy (UBE) assisted bilateral decompression in the treatment of lumbar disc herniation with imaging herniation on one side and clinical symptoms on the contralateral side.Methods:A total of 20 patients with lumbar disc herniation with imaging herniation on one side and clinical symptoms on the contralateral side treated with UBE from January 2022 to January 2024 in the Affiliated Hospital of Binzhou Medical University were retrospectively analyzed. There were 9 males and 11 females, aged 50.4±14.0 years (range, 23-72 years). The intervertebral disc herniation level included L 3-4 in 1 case, L 4-5 in 15 cases, and L 5S 1 in 4 cases. There were 10 cases on the left side and 10 cases on the right side. The duration of symptoms was 24.1±33.7 months (range, 1-120 months). Visual analogue scale (VAS) and Oswestry disability index (ODI) were used to evaluate postoperative pain relief and functional recovery. The clinical efficacy was evaluated by modified MacNab criteria at 6 months after operation. Results:All patients successfully completed the operation. The operation time was 90.3±24.6 min (range, 55-134 mins). The VAS scores of patients at 3 days, 1 month, 3 months and 6 months after operation were 3.6±0.9, 2.2±0.7, 1.2±0.5 and 1.0±0.6, respectively, which were lower than those before operation (6.4±0.8), and the differences were statistically significant ( F=668.728, P<0.001). The ODI at 3 days, 1 month, 3 months and 6 months after operation were 34.2%±4.7%, 28.7%±2.8%, 24.3%±2.1% and 20.5%±2.0%, respectively, which were lower than 69.4%±5.2% before operation, and the differences were statistically significant ( F=515.578, P<0.001). The clinical efficacy was evaluated by modified MacNab criteria at 6 months after operation. Among 20 patients, 18 cases were excellent, 1 case was good, and 1 case was fair. All patients were followed up for 9.1±2.1 months (range, 6-14 months). One patient had a dural tear during the operation, but the range was small and there was no defect, and no further treatment was performed. Numbness of the lower limbs occurred 1 day after operation, and the symptoms disappeared after symptomatic treatment. There was no recurrence of lower limb symptoms, lumbar instability, intervertebral space infection or other complications at the last follow-up. Conclusion:Bilateral decompression with UBE is effective in the treatment of lumbar disc herniation with imaging herniation on one side and clinical symptoms on the contralateral side, which can improve the lumbar pain and function of patients.

Objective:This study intends to analyze the differences of indexes between the death group and the survival group of CSA-AKI patients undergoing CRRT before, during, and after heart surgery, and at the beginning and the end of CRRT, and to study the risk factors affecting the death of patients, so as to provide guidance for improving the prognosis.Methods:From January 2020 to October 2022, a total of 101 patients (59 in the mortality group and 42 in the survival group) were admitted to the Department of Cardiac Surgery at the First Affiliated Hospital of Zhengzhou University for cardiac surgery complicated by acute kidney injury necessitating postoperative continuous renal replacement therapy (CRRT). A retrospective analysis of clinical data was conducted to ascertain the risk factors influencing the 30-day mortality rate.Results:The postoperative complications of the two groups showed that the mortality group had a large proportion of MODS and LCOS ( P<0.05). Multivariate regression analysis showed that intraoperative mean arterial depression, high SOFA score at the beginning of CRRT, high APACHE Ⅱ score at the beginning of CRRT, and low platelet at the end of CRRT were independent risk factors for death( P<0.05). ROC curve analysis shows that SOFA score and APACHE Ⅱ score at the beginning of CRRT have predictive value for the 30-day death risk of CSA-AKI patients receiving CRRT. Conclusion:Low intraoperative MAP, high SOFA and APACHE Ⅱ scores at the beginning of CRRT, and low platelets at the end of CRRT were independent risk factors for 30-day mortality risk in patients with CSA-AKI undergoing CRRT.

Objective To compare the clinical efficacy of digital 3D technology assisted and traditional one-hole split endoscopic surgery for lumbar spinal stenosis with degenerative scoliosis(LSS-DS).Methods Clinical data of 42 patients with LSS-DS who underwent one-hole split endoscopic surgery from January 2022 to December 2023 were retrospectively analyzed.Among them,20 cases were treated with digital 3D technology assisted one-hole split endoscopic surgery(3D group),and 22 cases were treated with traditional one-hole split endoscopic surgery(traditional group).The operation time,intraoperative blood loss,lateral articular surface preservation rate,Visual Analogue Scale(VAS)of lower extremity pain,Oswestry Disability Index(ODI)and modified MacNab criteria at the last follow-up were compared between the two groups.Results Both groups of patients were operated successfully.The operation time of the 3D group and the traditional group was(73.3±24.0)min and(65.7±23.8)min,respectively,with no significant difference(t=1.020,P=0.314).The intraoperative blood loss was(65.3±14.7)ml and(66.7±17.1)ml,respectively,with no significant difference(t=-0.298,P=0.767).The retention rate of lateral articular surface in the 3D group[(88.2±6.3)%]was significantly higher than that in the traditional group[(82.7±4.6)%,t=3.201,P=0.003].One patient in the traditional group had dural tear and was cured after conservative treatment.There were 3 cases of calf muscle venous thrombosis in the 3D group and 4 cases in the traditional group.All the 7 patients were given anticoagulant therapy and appropriately delayed time of ambulation.In the3D group,20 cases were followed up for6-13 months,with a mean of(8.2±2.0)months;in the traditional group,22 cases were followed up for 6-12 months,with a mean of(7.7±1.7)months.According to the modified MacNab criteria,the excellent and good rate was 95.0%(19/20)in the 3D group and 90.1%(20/22)in the traditional group at the last follow-up,and there was no significant difference between the two groups(Z=-0.311,P=0.756).The VAS score and ODI of the two groups were significantly improved at 3 months and 6 months after operation(all P=0.000),but there was no significant difference between the two groups at each time point(P>0.05).Conclusion The short-term efficacy of digital 3D technology assisted one-hole split endoscopic surgery in the treatment of LSS-DS is definite,and the symptoms of patients are significantly improved.
