ObjectiveTo investigate the effects of Huanglian Jiedutang （HLJDT） on cognitive function in mice with ischemic stroke （IS） and to elucidate whether its neuroprotective effects are mediated by inhibition of the nuclear factor-κB （NF-κB） signaling pathway and subsequent suppression of NF-κB-regulated neuronal apoptosis. MethodsAn IS model was established using middle cerebral artery occlusion （MCAO）. Sixty C57BL/6J mice were randomly assigned to five groups （n =12 per group）， i.e.， sham operation， model， HLJDT low-dose （3.9 g·kg^-1·d^-1）， HLJDT high-dose （7.8 g·kg^-1·d^-1）， and Ginkgo biloba extract （GBE， 31.2 mg·kg^-1·d^-1）. Post-operatively， neurological deficit scores （Longa score）， cerebral infarct volume assessed by 2，3，5-triphenyltetrazolium chloride （TTC） staining， and brain water content were evaluated. Learning and memory were assessed using new object recognition （NOR） and fear conditioning （FC） tests. Hippocampal pathology was examined via hematoxylin and eosin （HE） staining. Immunofluorescence detected expression of glial fibrillary acidic protein （GFAP， astrocyte marker）， cellular oncogene Fos （c-Fos， neuronal activation marker）， and glutamate decarboxylase 65 （GAD65）. Western blot measured nuclear factor-κB inhibitor protein α （IκBα）， phosphorylated IκBα （p-IκBα）， NF-κB p65， phosphorylated NF-κB p65 （p-NF-κB p65）， ionic calcium binding adapter molecule 1 （Iba-1）， tumor necrosis factor （TNF）-α， interleukin （IL）-1β， and apoptosis-related proteins， such as cleaved cysteinyl aspartate-specific protease 3 （Caspase-3）， B-cell lymphoma 2 （Bcl-2）， and Bcl-2-associated X protein （Bax）. Real-time quantitative PCR （Real-time PCR） was used to assess mRNA levels of Iba-1， TNF-α， IL-1β， NF-κB p65， cleaved Caspase-3， Bax， and Bcl-2. ResultsCompared with the sham group， the model group exhibited significantly increased neurological deficit scores， brain water content， and cerebral infarct volume （P<0.01）. Hippocampal CA1 neurons were disorganized， showing nuclear pyknosis and karyolysis. NOR exploration time and FC freezing time were significantly reduced （P<0.01）. GFAP and c-Fos expression were increased， while GAD65 expression was decreased （P<0.01）. Cleaved Caspase-3 and Bax were upregulated， Bcl-2 was downregulated， and the Bax/Bcl-2 ratio was elevated （P<0.01）. Expression levels of p-IκBα， p-NF-κB p65， IL-1β， TNF-α， and Iba-1 were significantly increased （P<0.01）. Compared with the model group， HLJDT high-dose， low-dose， and GBE groups showed significant improvements in all parameters （P<0.01）. Among them， the HLJDT high-dose group showed the most pronounced neuronal structural recovery and superior performance in NOR and FC tests （P<0.01）. In this group， GFAP and c-Fos decreased， GAD65 increased （P<0.01）， apoptosis-related protein expression was reversed， and NF-κB signaling and related inflammatory factor expression were suppressed （P<0.01）. ConclusionHLJDT ameliorates cognitive dysfunction in mice after IS， potentially by inhibiting the NF-κB signaling pathway， thereby reducing neuroinflammation and hippocampal neuronal apoptosis.

Objective: To systematically analyzes the impact of blood donor characteristics on red blood cell (RBC) quality and transfusion outcomes, and to provide a scientific basis for optimizing donor selection criteria and developing personalized transfusion strategies. Methods: A literature search was conducted across electronic databases including CNKI, VIP, Wanfang Data, PubMed, and Embase using combinations of keywords such as "donor characteristics", "blood storage lesion", "blood quality", and "transfusion outcomes" for summary and analysis. Results: Factors associated with the blood donor characteristics including demographic characteristics (sex, age, body mass index), lifestyle habits (smoking, alcohol consumption, exercise), and dietary or pharmacological exposures significantly influence blood storage stability and transfusion efficacy by modulating erythrocyte metabolism, oxidative stress levels, and immune properties. Conclusion: The complexity and diversity of the blood donor characteristics are associated with blood quality and transfusion outcomes. Future efforts should focus on refining donor selection criteria and establishing personalized transfusion strategies to enhance blood product quality and improve patient outcomes.

Objective:To investigate the phenomenon of hippocampal ferroptosis and its change in a rat model of chronic constriction injury(CCI)of the sciatic nerve,as well as the association between hippocampal ferroptosis and emotional disorders induced by neuro-pathic pain.Methods:A total of 32 male Sprague-Dawley rats were randomly divided into Sham group,CCI group,CCI+F group,and CCI+E group,with 8 rats in each group.The rats in the CCI+F group and the CCI+E group were given intraperitoneal injection of Ferrostatin-1(10 mg/kg)and Erastin(10 mg/kg),respectively,since day 7 after surgery for two consecutive days.Mechanical with-drawal threshold(MWT),paw withdrawal latency(PWL),and open field test(OFT)were measured before surgery and on days 7 and 14 after surgery.On day 14 after surgery,the rats were sacrificed to col-lect hippocampal tissue;Western blot was used to measure the levels of GPX4,xCT,and FTH1;related kits were used to measure the expression levels of MDA and GSH;HE staining,Nissl staining,and immunofluorescent staining were performed;transmission electron microscopy was used to observe the structural changes of the mito-chondria.Results:In terms of behavioristics,compared with the Sham group,the CCI group had significant reductions in MWT and PWL on day 7 after surgery(P<0.001),with further reductions from day 7 to day 14 after surgery(P<0.001);compared with the CCI group,the CCI+F group had significant increases in MWT and PWL on day 14 after surgery(P<0.001),and the CCI+E group had no significant change in MWT and a significant reduction in PWL(P<0.01).In terms of the OFT test,compared with the Sham group,the CCI group had significant reductions in total distance and number of central squares crossed(P<0.001)and a significant increase in immobility time(P<0.001);compared with the CCI group,the CCI+F group had significant increases in total distance and number of central squares crossed and a significant reduction in immobility time,while the CCI+E group had no significant changes in these indi-ces.In terms of biochemical results,compared with the Sham group,the CCI group had significant reductions in GPX4,xCT,and FTH1(P<0.01),a significant increase in MDA,and a significant reduction in GSH;compared with the CCI group,the CCI+F group had sig-nificant increases in GPX4,xCT,and FTH1(P<0.05),a significant reduction in MDA(P<0.001),and a significant increase in GSH(P<0.01),and the CCI+E group had significant reductions in xCT and FTH1,with no significant changes in MDA and GSH.In terms of morphology,compared with the Sham group,the CCI group had damage and necrosis of hippocampal neurons,significant reductions in Nissl bodies and c-Fos level(P<0.05),and significantly damaged mitochondrial cristae on day 14 after surgery;compared with the CCI group,the CCI+F group had intact structures of hippocampal neurons,significant increases in Nissl bodies and c-Fos(P<0.05),and relatively intact mitochondria,while there were no significant differences in c-Fos and Nissl bodies between the CCI+E group and the CCI group.The pairwise linear correlation analysis of PWL,MWT,GPX4,OFT,and c-Fos on day 14 after surgery showed a signifi-cantly positive correlation between any two indicators(P<0.01).Conclusion:Peripheral nerve injury triggers ferroptosis in the hippo-campus and causes anxiety and depression,thereby aggravating ferroptosis and accelerating the development of central hyperalgesia.

Objective To investigate the effect of diosmine on semen quality and sex hormone concentra-tion in patients with spermatovenous ligation.Methods Clinical data were retrospectively collected from January 2019 to January 2022 on patients with varicocele admitted to Department of Urology,General Hospital of Southern Theater Command,divided into a control group and a study group based on whether they had a history of Diosmine use after surgery.Clinical data from both groups were matched using propensity score matching.Sperm quality and sex hormone tests were then compared before surgery,three months after surgery and six months after surgery.Results There were 73 in the control group and 73 in the study group.Both groups were balanced in terms of age,BMI,seminal fluid volume and testosterone(P＞0.05).Sperm motility,forward motility and testosterone were all increased 3 and 6 months after surgery,and sperm malformations,sperm DNA fragment index,follicle stimulating hormone and luteinizing hormone were all reduced significantly(P＜0.05).The results were also better than those in the control group for total sperm motility,forward motility,testosterone,sperm DNA fragment index,follicle stimulating hormone and luteinizing hormone(P＜0.05).Conclusions Diosmine can help to restore semen quality and improve sex hormone concentration in patients with varicocele after Laparoscopic varicocelectomy.

Objective:To investigate preliminary results of chest wall reconstruction with local kiss flap following mastectomy for locally advanced breast cancer (LABC).Methods:Clinical data of the LABC patients receiving treatment at the Department of Breast Surgery, the First Affiliated Hospital of Zhengzhou University between June 2020 and July 2021 was retrospectively analyzed. All patients underwent modified radical mastectomy after neoadjuvant chemotherapy. And the local kiss flap was used for reconstruction of the secondary chest wall soft tissue defects. Two small local flaps were designed intraoperatively and harvested from inferior (flap A) and lateral (flap B) to the defect, respectively, resurfacing a large chest wall soft tissue defect side by side with primary closure of both two donor sites. The flap perfusion was routinely monitored postoperatively. Adjuvant systemic therapies were implemented based on both pre- and post-operative pathological results. And the adjuvant radiotherapy was started immediately after wound healed completely. All cases were followed up regularly.Results:A total of five female patients were included, with an average age of 53.4 (ranging from 41 to 71). Stage Ⅲ (T 3-4N 2-3M 0) breast cancer was diagnosed in all cases. After mastectomy, chest wall soft tissue defect was presented in all cases, ranging from 12.0 cm × 12.0 cm to 22.0 cm × 20.0 cm. The flap A measured from 7.0 cm × 7.0 cm to 14.0 cm × 13.0 cm and the flap B from 5.0 cm × 4.0 cm to 11.0 cm × 7.0 cm. Only 1 flap A suffered tip necrosis and the remnant flaps survived totally. All donor sites recovered uneventfully and no donor-site morbidity was noted. The mean post-operative follow-up period was 15.8 months (ranging from 13 to 20 months). No tumor recurrence or metastasis was noted in all patients, except one patient, who did not receive radiotherapy, suffered local recurrence 4 months after surgery. Conclusion:Given its simplicity and satisfying results, the local kiss flap is a feasible and reliable reconstructive option for chest wall soft tissue defect reconstruction after mastectomy in selected LABC patients.

Objective:To investigate the characteristics of primary catheter malposition (PCM) following totally implantable venous access port (TIVAP) implantation via the internal jugular vein (IJV) and management strategies.Methods:Clinical data of 587 consecutive breast cancer patients undergoing TIVAP implantation via the IJV performed by single team at the Department of Breast Surgery, the First Affiliated Hospital of Zhengzhou University from Aug 2017 to Aug 2022 was retrospectively analyzed.Results:A total of 593 TIVAP were implanted and PCM was found in 18 cases (3.0%). Four hundred and twenty five TIVAP were implanted via the right IJV with one PCM case (0.2%). One hundred and sixty eight TIVAP implantations were performed via the left IJV and PCM occurred in 17 cases (10.1%). The interventional management with a pigtail catheter was performed as a first-line strategy in 11 of the 18 PCM cases, with a success in 10 cases and failure in one. Three cases were successfully managed with the digital subtraction angiography (DSA)-guided open approach. Four cases underwent blind open procedure firstly and 2 suffered a failure.Conclusions:A higher incidence of PCM is found in TIVAP implantations via the left IJV than the right one. The interventional management with a pigtail catheter or the DSA-guided open procedure proves to be feasible for the correction of PCM.
