Erectile dysfunction (ED) is prevalent among men, but its relationship with dietary habits is uncertain. The aim of our study was to assess whether dietary patterns enhance erectile function by reviewing the literature published before August 1, 2022, via PubMed, Web of Science, and EMBASE databases. The data compiled included author details; publication dates, countries, treatments, patient numbers, ages, follow-ups, and clinical trial outcomes, such as ED cases, odds ratios (ORs), confidence intervals (CIs), and International Index of Erectile Function-5 (IIEF-5) scores with means and standard deviations. An analysis of 14 studies with 27 389 participants revealed that plant-based diets (OR = 0.71, 95% CI: 0.66-0.75; P < 0.00001), low-fat diets (OR = 0.27, 95% CI: 0.13-0.53; P = 0.0002), and alternative diets such as intermittent fasting and organic diets (OR = 0.54, 95% CI: 0.36-0.80; P = 0.002) significantly reduced ED risk. High-protein low-fat diets (hazard ratio [HR] = 1.38, 95% CI: 1.12-1.64; P < 0.00001) and high-carb low-fat diets (HR = 0.79, 95% CI: 0.55-1.04; P < 0.00001) improved IIEF-5 scores. Combined diet and exercise interventions decreased the likelihood of ED (OR = 0.49, 95% CI: 0.28-0.85; P = 0.01) and increased the IIEF-5 score (OR = 3.40, 95% CI: 1.69-5.11; P < 0.0001). Diets abundant in fruits and vegetables (OR = 0.97, 95% CI: 0.96-0.98; P < 0.00001) and nuts (OR = 0.54, 95% CI: 0.37-0.80; P = 0.002) were also correlated with lower ED risk. Our meta-analysis underscores a strong dietary-ED association, suggesting that low-fat/Mediterranean diets rich in produce and nuts could benefit ED management.

Objective To explore the correlation between lung injury and human neutrophil lipocalin(HNL)in rats with sepsis.Methods 45 rats were randomly divided into a control group,a sham group,and a model group.The model group was to construct a rat sepsis lung injury model,the sham group was to free cecum laparotomy and then close abdomen without ligation and puncture,and the control group was with healthy rats.Serum interleukin(IL)-6,IL-1β,tumor necrosis factor-a(TNF-α),and HNL in each group of rats were detected with reagent kit.Oxygenation index was detected by blood gas analysis system.Lung wet/dry(W/D)ratio was calculated.Patho-logical morphology of lung tissue was observed by HE staining,and lung injury score was calculated.Results There were no significant differences in IL-6,IL-1β,TNF-α,HNL levels,oxygenation index,lung tissue wet/dry ratio,and lung injury score between the control group and the sham group at 12,24 and 36 hours(all P＞0.05).Compared with the sham group,IL-6,IL-1β,TNF-α,HNL levels,oxygenation index,lung tissue wet/dry ratio,and lung injury score in the model group increased at 12,24 and 36 hours,with significant differences(all P＜0.05).At 12,24 and 36 hours,lung tissue structure of rats was normal in the control group,with no edema ob-served;there were only a few inflammatory cells in the lung tissue of rats from the sham group;while in the model group,lung tissue structure of rats was severely injured,pulmonary alveoli collapsed,and inflammatory cells were severely infiltrated,but pathology improved with time.In rats with sepsis and lung injury,HNL was positively cor-related with IL-6,IL-1β,TNF-α,lung wet/dry ratio,and lung injury scores(all P＜0.05),while negatively corre-lated with oxygenation index(P＜0.05).Conclusion In rats with sepsis lung injury,HNL increases significantly,with severe inflammation and aggravation in lung tissue wet/dry ratio and lung injury,while oxygenation index de-creases.HNL level is positively correlated with IL-6,IL-1β,TNF-α levels,lung tissue wet/dry ratio and lung inju-ry,but negatively correlates with oxygenation index.

Objective To investigate the clinical effect of posterior femoral composite tissue flap pedicled with inferior gluteal artery for repair of huge sacrococcygeal pressure injuries.Methods The clinical data of 11 patients with huge sacrococcygeal pressure injuries admitted to our hospital were retrospectively analyzed,with a mean wounds area of(205.3±15.3)cm2,and the depth of the wounds all reached the sacrococcygeal bone surface with partial sacrococcygeal necrosis.The inferior gluteal artery and its perforating branch were investigated with ultrasonic Doppler flow detector before operation,the posterior femoral composite tissue flap pedicled with inferior gluteal artery was designed according to the wound surface,and then the chronic sacrococcygeal wound was repaired.The operation time,intraoperative blood loss,wound healing,postoperative skin flap survival and occurrence of complications were recorded.The skin flap color,temperature and two-point discernability were monitored to evaluate skin flap sensory sensitivity.The visual analog scale(VAS)was used to evaluate the satisfaction of appearance.Results The operation time of patients was(2.8±0.1)hours and the intraoperative blood loss was(235.4±10.2)mL.The posterior femoral composite tissue flap pedicled with inferior gluteal artery of all the 11 patients survived.The distal part of the flap was necrotic in 1 case,which healed well after local debridement and suturing by amplification;other wounds healed well in the first stage without complications such as infection,fat liquefaction or hematoma.The skin flap has good color,soft texture,and good elasticity,with good healing in the donor area.There were significant differences in the skin flap temperature,two-point discernability and VAS score of appearance satisfaction between 12 months after operation and other time points(P＜0.05).Conclusion The posterior femoral composite tissue flap pedicled with inferior gluteal artery has a constant blood supply,without damage to the main blood vessels.It can be transposed at anterograde or retrograde direction,with simple operation and less damage,which can reconstruct flap sense,and has significant clinical efficacy in repairing huge sacrococcygeal pressure injuries.

BACKGROUND: Myocardial ischemia-reperfusion (I/R) is a serious and irreversible injury. Bone marrow-derived mesenchymal stem cells (MSCs) is considered to be a potential therapy for I/R injury due to the paracrine effects. High-mobility group box 1 (HMGB1) is a novel mediator in MSC and regulates the response of inflammation injury. Signal Transduction and Transcription Activator 3 (STAT3) is a critical transcription factor and important for release of paracrine factors. However, the relationship between HMGB1 and STAT3 in paracrine effect of MSC remains unknown. METHODS: In vitro, hypoxia/reoxygenation injury model was established by AnaeroPack System and examined by Annexin V flow cytometry, CCK8 assay and morphology observation. Detection of apoptotic proteins and protein expression of HMGB1 and STAT3 by Western blot. RESULTS: The conditioned medium of MSCs with or without LPS pretreatment was cocultured with H9C2 cells for 24 h before hypoxia treatment and MSC showed obvious cardiomyocytes protect role, as evidence by decreased apoptosis rate and improved cells viability, and LPS pretreated MSC exhibited better protect role than untreated MSC. However, such effect was abolished in HMGB1 deficiency group, silencing HMGB1 decreased the secretion of vascular endothelial growth factor (VEGF), hepatocyte growth factor (HGF), insulin growth factor (IGF), cell viability, and the expression of STAT3. Furthermore, STAT3 silence attenuated the protective effect of LPS in MSC. CONCLUSIONS These findings suggested that LPS improved MSC-mediated cardiomyocytes protection by HMGB1/STAT3 signaling.

OBJECTIVE: To investigate the mechanism of nucleolin (NCL) involved in lymphoma proliferation by regulating thymidine kinase 1 (TK1). METHODS: Twenty-three patients with diffuse large B-cell lymphoma (DLBCL) were selected and divided into initial treatment group (14 cases) and relapsed/refractory group (9 cases). Serum TK1 and C23 protein in peripheral blood mononuclear cells were detected. Cell models of CA46-NCL-KD (CA46-NCL-knockdown) and CA46-NCL-KNC (CA46-NCL-knockdown negative control) were established by lentivirus vector mediated transfection in Burkitt lymphoma cell line CA46. The half maximal inhibitory concentration (IC₅₀) of CA46-NCL-KD, CA46-NCL-KNC, and CA46 to adriamycin were detected by cell proliferation assay (MTS). The expression of NCL mRNA and protein in CA46-NCL-KD and CA46-NCL-KNC cells were dectected by Q-PCR and Western blot, respectively. The cell cycle of CA46-NCL-KD, CA46-NCL-KNC, and CA46 cells were detected by flow cytometry. The expression of TK1 protein in CA46-NCL-KD and CA46-NCL-KNC cells was detected by an enhanced chemiluminescence (ECL) dot blot assay. RESULTS: The level of serum TK1 in the initial treatment group was 0.43(0-30-1.01) pmol/L, which was lower than 10.56(2.19-14.99) pmol/L in the relapsed/refractory group (P<0-01), and the relative expression level of NCL protein in peripheral blood was also significantly lower. The IC₅₀ of CA46-C23-KD cells to adriamycin was (0.147±0.02) μg/ml, which was significantly lower than (0.301±0.04) μg/ml of CA46-C23-KNC cells and (0.338±0.05) μg/ml of CA46 cells (P<0.05). Compared with CA46-NCL-KNC cells, the expression of NCL mRNA and protein, TK1 protein decreased in CA46-NCL-KD cells, and the proportion of S phase and G₂/M phase also decreased, while G0/G1 phase increased in cell cycle. CONCLUSION The increased expression of NCL in DLBCL and CA46 cells indicates low sensitivity to drug. NCL may participate in regulation of lymphoma proliferation by affecting TK1 expression, thereby affecting the drug sensitivity.

Objective: To compare the efficacy of two induction regimens, namely, idarubicin combined with cytarabine (IA) versus the combination of homoharringtonine, daunorubicin, and cytarabine (HAD) , in adult patients with newly diagnosed de novo acute myeloid leukemia (AML) . Methods: From May 2014 to November 2019, 199 patients diagnosed with AML receiving either the IA or HAD regimens were assessed for overall survival (OS) , relapse-free survival (RFS) , as well as the CR rate and the MRD negative rate after induction therapy. The differences in prognosis between the two induction therapy groups was assessed according to factors, including age, white blood cell (WBC) count, NPM1 mutation, FLT3-ITD mutation, 2017 ELN risk stratification, CR(1) transplantation, and the use of high-dose cytarabine during consolidation therapy, etc. Results: Among the 199 patients, there were 104 males and 95 females, with a median age of 37 (15-61) years. Ninety patients received the IA regimen, and 109 received the HAD regimen. Comparing the efficacy of the IA and HAD regimens, the CR rates after the first induction therapy were 71.1% and 63.3%, respectively (P=0.245) , and the MRD negative rates after the first induction therapy were 53.3% and 48.6%, respectively (P=0.509) . One patient in the IA group and two in the HAD group died within 60 days after induction. The two-year OS was 61.5% and 70.6%, respectively (P=0.835) , and the two-year RFS was 51.6% and 57.8%, respectively (P=0.291) . There were no statistically significant differences between the two groups. Multivariate analysis showed that the ELN risk stratification was an independent risk factor in both induction groups; CR(1) HSCT was an independent prognostic factor for OS and RFS in the IA patients and for RFS in the HAD patients but not for OS in the HAD patients. Age, WBC level, NPM1 mutation, and FLT3-ITD mutation had no independent prognostic significance. Conclusion: The IA and HAD regimens were both effective induction regimens for AML patients.

ObjectiveTo explore the mechanism of Xueniao capsule in the treatment of acute pyelonephritis （APN） by network pharmacology and experimental verification. MethodThe effect of Xueniao capsule on APN was investigated based on the APN model in rats. The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， Chemistryl Database， and SymMap were searched for the chemical components of Smilacis Chinae Rhizoma，Coicis Semen， and Trachycarpi Petiolus. The target information of the components was collected from PharmMapper and SwissTargetPrediction， and disease target information from Therapeutic Target Database （TTD）， DrugBank， DisGeNET， GeneCards， and Online Mendelian Inheritance in Man（OMIM）. The key genes of Xueniao capsule for APN underwent Gene Ontology（GO） and Kyoto Encyclopedia of Genes and Genomes（KEGG） pathway enrichment analyses by Metascap. Real-time quantitative polymerase chain reaction （PCR） and Western blot were employed to verify the prediction results. ResultCompared with the blank group and the sham operation group， the model group showed an increased ratio of the left kidney to the right kidney and organ index（P<0.05， P<0.01），up-regulated white blood cells （WBC），neutrophils （NEUT），monocytes （MONO）， and lymphocytes （LY）（P<0.05， P<0.01）， and elevated levels of nuclear factor-κB（NF-κB）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α）（P<0.05， P<0.01）. Compared with the model group， the norfloxacin group， the low- and high-dose Xueniao capsule groups showed a decreased ratio of the left kidney to the right kidney and organ index（P<0.05， P<0.01）， dwindled levels of WBC， NEUT， MONO， and LY（P<0.05， P<0.01）， and reduced levels of NF-κB， IL-6， and TNF-α（P<0.05， P<0.01）. The medium-dose Xueniao capsule group showed a decreased ratio of the left kidney to the right kidney and organ index（P<0.05， P<0.01）， reduced levels of WBC， NEUT， MONO， and LY（P<0.05， P<0.01）， and dwindled levels of IL-6 and TNF-α（P<0.05， P<0.01）. Network pharmacological analysis revealed 17 active compounds from Smilacis Chinae Rhizoma， 18 active compounds from Coicis Semen， six active compounds from Trachycarpi Petiolus， and 39 key genes for the treatment of APN in Xueniao capsule. GO enrichment analysis demonstrated 704 biological processes， 22 cellular components， and 59 molecular functions. Sixty-two pathways were enriched in KEGG enrichment analysis. The experimental verification results showed that compared with the blank group， the model group showed increased mRNA expression of prostaglandin-endoperoxide synthase 2 （PTGS2）， mitogen-activated protein kinase 1 （MAPK1）/extracellular signal-regulated protein kinase 2 （ERK2），phosphoinositide 3 kinase （PI3K），protein kinase B2（Akt2），Janus kinase 2 （JAK2），and signal transducer and activator of transcription 3 （STAT3）and protein expression of PI3K， Akt2， JAK2， and STAT3 （P<0.05， P<0.01）. Compared with the model group， the low-dose Xueniao capsule group showed decreased mRNA expression of MAPK1， PI3K， JAK2， and STAT3 and protein expression of PI3K， JAK2， and STAT3 （P<0.05， P<0.01）. The medium-dose Xueniao capsule group showed decreased mRNA expression of MAPK1， PTGS2， PI3K， JAK2， and STAT3， and protein expression of PI3K， JAK2， and STAT3 （P<0.05， P<0.01）. The high-dose Xueniao capsule group showed reduced mRNA expression of PTGS2， MAPK1， PI3K， Akt2， JAK2， and STAT3 and protein expression of PI3K， Akt2， JAK2， and STAT3 （P<0.05， P<0.01）. ConclusionXueniao capsule has a certain curative effect on APN via multiple targets and multiple pathways. The mechanism may be related to the inhibition of the PI3K/Akt signaling pathway and the JAK2/STAT3 signaling pathway.
