Objective:To explore the prognostic values of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio(PLR)and NLR-PLR score for carcinoma(HCC)patients undergoing liver transplantation(LT).Methods:From July 2015 to October 2021, clinical data are retrospectively reviewed for 110 HCC patients undergoing orthotopic LT at Third Hospital of Hebei Medical University.The values of NLR and PLR were calculated.And the cut-off values of NLR and PLR were obtained by receiver operating characteristic (ROC) curve and then grouped according to the cut-off values.Survival time is analyzed by Kaplan-Meier method and Log-rank test performed for inter-group comparison.Univariate and multivariate analyses are performed based on Cox proportional risk regression model.NLR <3.37 and PLR <105.96 are denoted as 0 point while NLR ≥3.37 and PLR ≥105.96 as 1 point.Two points are added up as NLR-PLR score.According to NLR-PLR score, they are divided into 3 groups of 0, 1 and 2.Results:Median overall survival(OS)is 27 months in patients with NLR-PLR score 0, 26.5 months in patients with NLR-PLR score 1 and 6 months in patients with NLR-PLR score 2.Median OS in patients with NLR-PLR score 2 is significantly shorter than that in those with NLR-PLR score 0/1.And the difference is statistically significant( P<0.001).Median disease-free survival(DFS)is 24.5 months in NLR-PLR 0 group, 24 months in NLR-PLR 1 group and 6 months in NLR-PLR 2 group.The difference is statistically significant( P=0.002).Univariate analysis show that Child-Pugh grade, MELD score, NLR/PLR level, NLR-PLR score, complying with University of California San Francisco Criteria(UCSF)criteria and absence/presence of microvascular invasion(MVI)have an impact on patient survival.Further multivariate analysis show that NLR-PLR score, complying with UCSF criteria and MELD score are independent risk factors affecting patients' prognosis and survival. Conclusions:NLR, PLR and NLR-PLR score may predict long-term survival of patients.And NLR-PLR score is an independent risk factor for patient survival.It has more predictive value than NLR/PLR.

Objective: To investigate the role of Portulaca oleracea (POL) in promoting revascularization and re-epithelization as well as inhibiting iron aggregation and inflammation of deep tissue pressure injury (DTPI). Methods: The hydroalcoholic extract of POL (P) and aqueous phase fraction of POL (PD) were prepared based on maceration and liquid–liquid extraction. The number of new blood vessels and VEGF-A expression level were assessed using H&E stain and Western blot on injured muscle to examine the role of POL different extracts in vascularization. The iron distribution and total elemental iron of injured muscle were detected using laser ablation inductively coupled plasma mass spectrometry (ICP-MS) and Perls’ staining to determine whether POL extracts can inhibit the iron accumulation. Besides, the ability of POL extracts to promote wound healing by combining re-epithelization time, inflammation degree and collagen deposition area were comprehensively evaluated. Results: In vitro, we observed a significant increase in HUVEC cell viability, migration rate and the number of the tube after P and PD treatment (P < 0.05). In vivo, administration of P and PD impacted vascularization and iron accumulation on injured tissue, evident from more new blood vessels, higher expression of VEGF-A and decreased muscle iron concentration of treatment groups compared with no-treatment groups (P < 0.05). Besides, shorter re-epithelization time, reduced inflammatory infiltration and distinct collagen deposition were associated with administration of P and PD (P < 0.05). Conclusion: POL extract administration groups have high-quality wound healing, which is associated with increased new blood vessels, collagen deposition and re-epithelization, along with decreased iron accumulation and inflammatory infiltration. Our results suggest that that POL extract is beneficial to repair injured muscle after ischemia–reperfusion, highlighting the potential of POL in the DTPI treatment.

Objective:To observe the changes of plasma oxytocin (OT), arginine vasopressin (AVP) and anxiety after exercise intervention in male opioids-dependent patients.Methods:Forty-five male opioids addicts who met the inclusion criteria and voluntarily participated in exercise rehabilitation were enrolled.According to stratified random sampling, all subjects were divided into exercise group ( n=22) and control group( n=23). Exercise group attended aerobic exercise combined with resistance training intervention, 5 times per week for 8 weeks.Aerobic exercise was mainly treadmill and elliptical, while resistance training was based on strength and endurance training.Subjects completed self-rating anxiety scale (SAS) and Chinese perceived stress perception scale (CPSS) before and after intervention, as well as physical fitness tests. Besides, plasma OT and AVP levels were detected.Independent sample t-test, paired sample t-test, and Chi-square test were conducted by using SPSS 20.0 software. Results:Before the intervention, there were no significant differences between the two groups in demography, drug history, SAS, CPSS, plasma OT and AVP(all P>0.05). The overall anxiety detection rate was 66.67%, the scores of SAS and CPSS were both higher than the Chinese norm, and the difference was significant(both P<0.01) . After the intervention, the levels of plasma AVP, the scores of SAS and CPSS in the exercise group (AVP(19.57±2.23)pg/ml, SAS(50.17±10.09), CPSS(36.59±6.36)) were significantly lower than those in the control group (AVP(22.53±2.56)pg/ml, SAS(57.12±12.00), CPSS(43.09±5.57), all P<0.05), and plasma OT((61.98±5.27) pg/ml) was significantly higher than that in the control group ((54.64±7.62) pg/ml)( P<0.01). Compared with baseline, maximal oxygen uptake(VO 2max), 1 min push-ups and sitting body flexion increased significantly in the exercise group (all P<0.05). Conclusion:Opioids drug addicts were prone to excessive stress and anxiety and other negative emotions in the process of drug withdrawal. Eight-week aerobic combined with resistance exercise changed the plasma OT and AVP levels of opioids addicts, effectively alleviated the perceived stress, improved the anxiety state and their health related fitness level.

Objective To study appliction value of quantitative dynamic contrast enhanced MRI(T1-DCE MRI)in preoperative grading of brain glioma.Methods 80 patients who were pathologically confirmed with a tumor grade (WHO grade Ⅰ 20 cases, grade Ⅱ 20 cases,grade Ⅲ 20 cases and grade Ⅳ 20 cases).All patients were examined with MR enhancements and T1-DCE MRI. The original perfusions imaging datas were analyzed using the GE Omni Kinetic software,which produced the transfer constant (Ktrans )map,the rate constant (Kep )map and fractional volume (Ve )map.Choose ROI and get values of Ktrans ,Kep and Ve .Pearson correlation was carried out to analyze the correlation between values of Ktrans ,Kep ,Ve of different grades of gliomas and pathology classifications.The Ktrans ,Kep and Ve values of the different grade gliomas were statistically analyzed using an ANOVA .Receiver operator characteristics (ROC)curve was used to analyze sensitivity and specificity of permeability parameters.Results The Ktrans ,Kep and Ve values of each levels has a strong correlation with pathological grading (r=0.95 1,0.804,0.766).There was obviously statistically significant difference between different grade groups(P < 0.01 )by Ktrans .Kep values have statistically difference between different grades except grade Ⅱ and Ⅲ.Ve values were different between different grades except grade I andⅡand grade Ⅲ and IV.Accord-ing to ROC curve,Ktrans seemed to be a better parameter for evaluating the tumor grade with the highest sensitivity and specificity. With the cutoff thresholds of Ktrans of 0.1 60,0.420 and 0.935,different grades of glioma can be differentiated with sensitivities of 90%,95%,95% and specificities of 95%,95%,85% respectively.Conclusion Quantitative analysis of microcirculation perfusion status of different grade gliomas by Ktrans values obtained from T1-DCE MRI can assessment the degree of the destruction of the blood brain barrier and evaluate the grade of gliomas more accurately before operation.

BACKGROUND:Ischemia microenvironment contributes mostly to the low survival rate of rat bone marrow mesenchymal stem cells after transplantation. Hydrogen sulfide (H2S) can protect various cells and tissue models against apoptosis and injury.
OBJECTIVE:To detect the cellapoptosis and viability, content of H2S in supernatant, and the expression of H2S synthetase after different time of hypoxia and serum deprivation cultivation of rat bone marrow mesenchymal stem cells.
METHODS:The passage 3 rat bone marrow mesenchymal stem cells were divided into five different cultivation time groups:0-, 3-, 6-, 12-and 24-hour groups. After enough hypoxia and serum deprivation cultivated time, the cellapoptosis was detected by SubG1, the cellviability was determined by cellcounting kit-8, the content of H 2S in supernatant was measured by N,N-dimethyl-p-phenylenediamin and the expression of H2S synthetase by RT-PCR and western blot.
RESULTS AND CONCLUSION:Compared to the normal cultivation group, after different hypoxia and serum deprivation cultivated time, the cellapoptosis increased and cellviability decreased significantly. The longer hypoxia and serum deprivation cultivated time caused the more cellapoptosis and the lower cellviability. The contents of H2S and its synthetase were also suppressed by hypoxia and serum deprivation cultivation. The difference was statistical y significant. These findings suggest that hypoxia and serum deprivation cultivation can inhibit the generation of H 2 expression of its synthetase.

Objective To observe the effect of interventional occlusion for the treatment of residual leak after repaired of patent ductus arteriosus (PDA).Methods A total of 23 patients with residual leak after repaired of PDA underwent interventional occlusive procedures.Original operative methods:15 patients performed surgical ligation of PDA,4 patients performed neoplasty under cardiopulmonary bypass,4 patients performed transcatheter occlusion.Twenty-three patients were treated by standard interventional occlusion.The lateral descending aortographies and echocardiography were performed to evaluate the immediate results after occlusion 15 min.Echocardiography was rechecked after occlusion 1 week,1 month to find whether there was residual shunt and recanalization.Results Twenty-three patients per formed aortographies in operation showed residual leak.The mean minimum diameter of the residual leak was 2-8 (3.7 ± 1.4) mm.After occlusion 15 min,heart murmur disappeared,the form of interventional occlusive procedures was better.One patient had little residual leak,22 patients (95.65％,22/23) residual leak disappeared.Aftertreated 1 week,1 month,aortographies and echocardiography showed the form of interventional occlusive procedures was better,all patients had no residual leak.Conclusion Residual leak after repaired of PDA can be treated safely and effectively with interventional occlusive procedures.
