Objective To evaluate the effect of Kaixin San(KXS)combined with fluoxetine on hippocampal neural stem cells in mice with chronic stress stress and depression.Methods A mouse model of depression was constructed using the method of chronic unpredictable stress stress,and the highest dose of KXS water extract and fluoxetine for clinical application was given for 28 days,and behavioral tests were carried out.Nissl staining was used to detect the pathological status of hippocampal tissues in mice.The expression of TUNEL and Nestin in mouse hippocampus was determined by immunofluorescence.Western blotting was used to detect the expressions of apoptotic proteins cleaved caspase-3 and caspase-3,pyroptosis proteins GSDMD and cleaved caspase-1,as well as the expression of neural stem cell marker Nestin in the hippocampus,and the expression of Wnt/β-catenin signaling pathway-related proteins in the hippocampus.Results The combination of KXS extract and fluoxetine can significantly improve the depression-like behavior of model mice,and the effect is better than fluoxetine alone.The combination inhibited the activation of apoptosis and pyroptosis signaling pathways in the hippocampus when used alone with high-dose fluoxetine,significantly upregulated the expression of Nestin,and regulated the expression of Wnt/β-catenin signaling pathway protein.Conclusion The combination of KXS and high-dose fluoxetine can improve apoptosis and pyroptosis in the hippocampus of stress stress and depression model mice,and upregulate the expression of neural stem cell marker Nestin by regulating the Wnt/β-catenin signaling pathway,which may be a key link to improve the antidepressant effect of the combination drug.

Background and Aims:Laparoscopic pancreaticoduodenectomy(LPD)has become a preferred approach for periampullary tumors,yet delayed gastric emptying(DGE)remains a frequent complication that hampers postoperative recovery.The nasojejunal feeding tube(NJT)is commonly used for early enteral nutrition,but its impact on DGE is controversial.This study aimed to evaluate whether intraoperative NJT placement increases the risk of DGE after LPD and to assess its influence on postoperative recovery outcomes.Methods:A retrospective cohort of 319 patients who underwent LPD at Provincial Hospital Affiliated to Shandong First Medical University from April 2017 to November 2023 was analyzed.Patients were divided into two groups based on intraoperative NJT placement(NJT group,n=200;non-NJT group,n=119).The incidence of DGE and postoperative outcomes were compared.Multivariate logistic regression and propensity score matching(PSM)were performed to identify independent risk factors for DGE.Results:The incidence of grade B/C DGE was significantly higher in the NJT group than in the non-NJT group(36.5%vs.21.8%,P=0.006).NJT placement was associated with longer postoperative hospital stay and higher hospitalization costs(both P<0.05).Multivariate analysis revealed intraoperative NJT placement(OR=1.960,95%CI=1.142-3.363,P=0.015)and intraoperative blood loss>400 mL(OR=1.921,95%CI=1.155-3.194,P=0.012)as independent risk factors for DGE.These findings were consistent after PSM.Conclusions:Prophylactic intraoperative NJT placement confers no additional benefit for postoperative recovery after LPD and is associated with a higher risk of DGE,prolonged hospitalization,and increased medical costs.Routine NJT placement should therefore be avoided,and individualized strategies should be adopted to minimize postoperative complications and enhance recovery.

Objective To investigate the beneficial effect of Kai-Xin-San combined with fluoxetine in improving depression-like behaviors on chronic unpredictable mild stress(CUMS)induced depression model mice.Methods The present study aimed to assess the potential of Kai-Xin-San in combination with fluoxetine to ameliorate depression-like behaviors in a CUMS induced mouse depression model.Behavioral tests,such as the sucrose preference test were employed to evaluate the efficacy of the treatment.Additionally,the levels of suppressed stress factors were measured using the ELISA method.The morphology of hippocampal tissue was evaluated using the HE staining method,Nissl Staining and TUNEL staining methods.Furthermore,western blotting analysis was utilized to determine the expression levels of proteins such as Caspase-3,and Caspase-9.Results The co-administration of Kai-Xin-San and fluoxetine resulted in a significant increase in sucrose preference rate in model mice.This effect was comparable to that of fluoxetine alone at the standard clinical dose.Furthermore,the combination treatment up-regulated the levels of suppressed stress factors,reduced the apoptosis of hippocampus induced by depression and regulated the apoptosis signaling pathway in hippocampus.Conclusion The combination of Kai-Xin-San and fluoxetine has been shown to be an effective treatment for depression-like behavior in animal models,resulting in a reduction in the required clinical dosage of fluoxetine.This effect may be attributed to the up-regulation of neurotransmitter expression,inhibition of stress axis activation,and central nervous inflammation.

Osteoarthritis(OA)is a chronic progressive osteoarthropathy in the elderly.Osteoclast activation plays a crucial role in the occurrence of subchondral bone loss in early OA.However,the specific mechanism of osteoclast differentiation in OA remains unclear.In our study,gene expression profiles related to OA disease progression and osteoclast activation were screened from the Gene Expression Omnibus(GEO)repository.GEO2R and Funrich analysis tools were employed to find differentially expressed genes(DEGs).Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses demonstrated that chemical carcinogenesis,reactive oxygen species(ROS),and response to oxidative stress were mainly involved in osteoclast differentiation in OA subchondral bone.Furthermore,fourteen DEGs that are associated with oxidative stress were identified.The first ranked differential gene,heme oxygenase 1(HMOX1),was selected for further validation.Related results showed that osteoclast activation in the pathogenesis of OA subchondral bone is accompanied by the downregulation of HMOX1.Carnosol was revealed to inhibit osteoclastogenesis by targeting HMOX1 and upregulating the expression of antioxidant protein in vitro.Meanwhile,carnosol was found to alleviate the severity of OA by inhibiting the activation of subchondral osteoclasts in vivo.Our research indicated that the activation of osteoclasts due to subchondral bone redox dysplasia may serve as a significant pathway for the advancement of OA.Targeting HMOX1 in subchondral osteoclasts may offer novel insights for the treatment of early OA.

Objective:To investigate the effect of preoperative use of diuretics on cardiac surgery-associated acute kidney injury(CSA-AKI)in elderly patients.Methods:In this single-center retrospective study, 1 638 patients aged ≥60 years and undergone cardiac surgery(including coronary artery bypass grafting, valve replacement and valvuloplasty)in the Department of Cardiovascular Surgery, Linyi People's Hospital between January 2015 and December 2022 were recruited.The last preoperative serum creatinine(SCr)level was taken as the baseline value, and AKI was diagnosed according to the Kidney Disease Improving Global Outcomes(KDIGO)criteria.Patients were divided into an AKI group and a non-AKI group according to whether AKI occurred after surgery.The clinical characteristics of the two groups were compared, and the effect of preoperative use of diuretics on CSA-AKI was evaluated by multivariate Logistic regression analysis.Results:Of 1638 patients enrolled in the study, 284 patients(17.3%)developed CSA-AKI.Compared with the non-AKI group, there were higher proportions of patients in the AKI group receiving furosemide(62.7% or 178/284 vs.46.2% or 626/1 354, χ2=25.397, P<0.001), spironolactone(70.1% or 199/284 vs.49.9% or 676/1 354, χ2=38.284, P<0.001), and hydrochlorothiazide(8.1% or 23/284 vs.3.5% or 47/1354, χ2=12.288, P<0.001). The number of diuretics in the AKI group was higher than in the non-AKI group[2(0, 2) vs.1(0, 2), Z=-6.381, P<0.001], and the proportion of patients using ≥2 diuretics was higher in the AKI group than in the non-AKI group(70.1% or 199/284 vs.49.0% or 664/1354, χ2=41.652, P<0.001). Multivariate Logistic regression analysis showed that, after adjusting for hypertension, diabetes mellitus, hypoalbuminemia, NYHA functional class Ⅲ/Ⅳ, cardiopulmonary bypass during surgery, operative duration≥6 h, postoperative blood transfusion>600 ml, postoperative use of >3 vasoactive drugs and other variables, preoperative use of ≥2 diuretics remained an independent risk factor for CSA-AKI in elderly patients( OR=1.580, 95% CI: 1.042-2.396, P=0.031). Conclusions:AKI is a common complication after cardiac surgery in elderly patients.Preoperative use of ≥2 diuretics used may be an independent risk factor for CSA-AKI.

Objective:To compare ultrasound (US) guided versus computed tomography (CT) guided radiofrequency ablation (RFA) in treatment of early hepatocellular carcinoma (HCC).Methods:The data of 133 patients with early HCC treated by RFA in the Department of Hepatobiliary Surgery of Shandong Provincial Hospital from February 1, 2015, to January 31, 2017, was analyzed retrospectively. These patients were divided into two groups: the US-guided group and the CT-guided group. The clinical data was collected and the factors affecting prognosis were analyzed.Results:Compared with the CT-guided group, the operation time of the US-guided group was significantly shorter [(29.0±12.0)min vs. (55.0±19.0)min, P<0.05], but the number of ablation sessions per tumor was significantly less [(1.1±0.3) vs. (2.0±0.6), P<0.05]. There was no significant difference in the complete ablation rates, postoperative complication rates and postoperative length of hospital stay between the two groups ( P>0.05). The CT-guided group was superior to the US-guided group in the local tumor recurrence and progression-free survival rates ( P<0.05). On multivariate analysis, CT-guided RFA was an independent protective factor for local tumor recurrence ( HR=0.266, 95% CI: 0.073-0.967, P<0.05) and progression-free survival ( HR=0.415. 95% CI: 0.213-0.806, P<0.05), while AFP >20 ng/ml ( HR=4.821, 95% CI: 1.714-13.560, P<0.05) was an independent risk factor for progression-free survival. Conclusion:CT-guided percutaneous RFA was superior to US-guided RFA in local treatment of early HCC, probably related to more needle placements and longer ablation time under CT guidance.

AIM: To investigate the clinical application value of trazodone combined with cognitive behavioral therapy on heroin addicts during the period of community detoxification. METHODS: A total of 140 heroin addictive patients treated by community detoxification management were randomly divided into four groups, 35 patients were given trazodone combined with cognitive behavioral therapy (T+P group), 35 patients were given a single trazodone therapy (T group), 35 patients were given a single cognitive behavioral therapy (P group), and 35 patients were only given community detoxification management (S group), the course of the treatment lasted for 12 weeks. At the time-point of baseline and the weekends 4, 8 and 12 after treatment, four groups were scored by Hamilton anxiety rating scale (HAMA), Hamilton depression rating scale (HAMD), Pittsburgh sleep quality index scale (PSQI), psychological craving rating scale (PCS), Chinese perceived stress scale (CPSS), and urine morphine positive rate. The safety was evaluated with Treatment Emergent Side-effect Scale (TESS) and laboratory test. RESULTS: A total of 125 patients completed the 12 weeks of treatment. HAMA, HAMD and PSQI scores of T+P group and T group on weekends 4, 8 and 12 were significantly reduced when compared with baseline, respectively (P< 0.05). HAMA and HAMD scores of P group on weekends 4, 8 and 12 were significantly decreased when compared with baseline, respectively (P< 0.05). PSQI scores of P group on weekends 8 and 12 were significantly decreased when compared with baseline, respectively (P< 0.05). HAMA, HAMD and PSQI scores of S group on weekend 12 were significantly reduced when compared with baseline, respectively (P< 0.05). There were significant differences on the PCS and CPSS scores between T+P group, T group, P group and S group on weekends 4, 8 and 12, respectively (P< 0.05). There also showed statistically significant differences on the urine morphine positive rates between T+P group and S group on weekends 4, 8 and 12, respectively (P< 0.05). There was no significant difference on the TESS score between T+P group and T group (P> 0.05). CONCLUSION: Trazolone combined with cognitive behavior therapy can significantly improve the negative emotions, sleep quality and other related mental symptom of heroin addiction patients in the community detoxification period, and play a positive role in improving the quality of community detoxification management.

Objective: To investigate the clinical effect of the reserve-flow anterolateral thigh perforator flap based on aesthetics concept to repair soft tissue defect around the knee joint. Methods: From June 2016 to April 2017, 10 patients with skin and soft tissue defects around the knee joint were admitted to Mingzhou Hospital of Zhejiang University. The area of the soft tissue defects around the ankle were ranged from 5.0 cm × 3.0 cm to 11.0 cm × 7.5 cm after debridement. The anterolateral thigh perforator flaps were designed on the ipsilateral lateral thigh, according to the results of preoperative perforator detection. The reserve-flow anterolateral thigh perforator flaps based on aesthetic concept were used to repair the wound through the subcutaneous tunnel. The flaps were 5.5 cm × 3.5 cm to 12.0 cm × 8.0 cm in size. The donor sites were directly closed. Results: The flaps of 9 patients completely survived, however, epidermal necrosis occurred to 1 patient, at the distal end of the flap, about 1 cm × 1 cm in size. It completely healed after dressing change for 1 week. The follow up time was from 8 to 15 months (mean 12 months). The flaps were satisfactory in appearance, good in the elasticity, nearly normal in color, and had protective sensation. The two-point discrimination perception ranged from 9 to 13 mm(mean 10 mm). The donor and recipient sites only remained linear scars, with no depression deformity. The lower limb functions were normal. Conclusions The reverse-flow anterolateral thigh flap based on aesthetic concept, is an alternative method to repair the soft tissue defect around the knee joint, and protect the donor site to the maximum extent.
