Objective To investigate the dynamic changes of Th 17 ,NK and IFN-γ,IL-17 in periop-erative patients with lung cancer .Methods Twenty cases of patients with lung cancer surgery were chosen ran-domly.Ten cases of healthy were used as control .We detected the express of Th17,NK,IFN-γand IL-17.Re-sults Compared with the control group , the levels of Th17 and IL -17 increased significantly in lung cancer group(P<0.05);Compared with the pre -operation,the levels of Th17 and IL-17 increased significantly after 1st day of lung cancer surgery .However,the levels of NK and IFN -γdecreased significantly .The expression of Th17 and IL-17 decreased obviously after 5 days of lung cancer surgery .However,the levels of IFN -γin-creased significantly(P<0.05).The correlation analysis showed that there was a positive correlation between Th17 and IL-17A,NK and IFN-γof peripheral blood with lung cancer patients (P<0.01),negative correla-tion between Th17 and NK,IFN-γof peripheral blood with lung cancer patients (P<0.05).Conclusion The immune suppress before activating at perioperative ,it is important for lung cancer patients to detect the levels of Th17,IL-17,NK,IFN-γin peripheral blood .

Objective To study the changes of CD4 +/CD8 +T cells ratio and TGF -β,IL-4,IL-6 levels in lung cancer patients during the perioperative period and to analyze the clinical significance .Methods Flow cytometer and Elisa were used to analyze the CD 4 +/CD8 +T cells ratio and TGF-β,IL-4,IL-6 levels in peripheral blood sapmles from 20 patients with lung cancer during the perioperative period and 10 healthy con-trolsR. esults Before operation ,the ratios of CD4 +T and CD8 +T cells from 20 patients with lung cancer were (46.26 ±4.26)%and(43.15 ±5.18)%, respectively.On the fifth day after operation ,the ratios of CD4 +T and CD8 +T cells were(44.30 ±4.25)%and(39.80 ±2.53)%.TGF-β,IL-4 and IL-6 levels in 20lung cancer patients were(240.51 ±46.37)pg/mL,(19.85 ±2.52)pg/mL,and(129.28 ±33.06)pg/mL,respectively.On the fifth day after operation,TGF-β,IL-4 and IL-6 levels were(210.79 ±36.94)pg/mL,(17.37 ±2.57) pg/mL,and(107.28 ±27.83) pg/mL.The differences of above parameters between the preoperative period and the fifth day after operation were statistically significant ( P<0.05) . Conclusion The immune suppression oc-curs before its recovery during perioperative period ,the changes of CD4 +/CD8 +T cells ratio and TGF-β,IL-4 and IL-6 levels have significance on monitoring the progress and prognosis of patients with tumor .

Background::Hypothermia therapy has been suggested to attenuate myocardial necrosis; however, the clinical implementation as a valid therapeutic strategy has failed, and new approaches are needed to translate into clinical applications. This study aimed to assess the feasibility, safety, and efficacy of a novel selective intracoronary hypothermia (SICH) device in mitigating myocardial reperfusion injury.Methods::This study comprised two phases. The first phase of the SICH was performed in a normal porcine model for 30 minutes ( n = 5) to evaluate its feasibility. The second phase was conducted in a porcine myocardial infarction (MI) model of myocardial ischemia/reperfusion which was performed by balloon occlusion of the left anterior descending coronary artery for 60 minutes and maintained for 42 days. Pigs in the hypothermia group ( n = 8) received hypothermia intervention onset reperfusion for 30 minutes and controls ( n = 8) received no intervention. All animals were followed for 42 days. Cardiac magnetic resonance analysis (five and 42 days post-MI) and a series of biomarkers/histological studies were performed. Results::The average time to lower temperatures to a steady state was 4.8 ± 0.8 s. SICH had no impact on blood pressure or heart rate and was safely performed without complications by using a 3.9 F catheter. Interleukin-6 (IL-6), tumor necrosis factor-α, C-reactive protein (CRP), and brain natriuretic peptide (BNP) were lower at 60 min post perfusion in pigs that underwent SICH as compared with the control group. On day 5 post MI/R, edema, intramyocardial hemorrhage, and microvascular obstruction were reduced in the hypothermia group. On day 42 post MI/R, the infarct size, IL-6, CRP, BNP, and matrix metalloproteinase-9 were reduced, and the ejection fraction was improved in pigs that underwent SICH.Conclusions::The SICH device safely and effectively reduced the infarct size and improved heart function in a pig model of MI/R. These beneficial effects indicate the clinical potential of SICH for treatment of myocardial reperfusion injury.

Scars are classified into 5 types:Superficial scars,hypertrophic scars,atrophic scars,depressed scars,and keloid.These types are primarily characterized by abnormal production of fibroblasts and collagen,as well as the disorderly arrangement of connective tissue.Laser treatment for scars involves the coordinated activation of various signaling pathways and cytokines.However,the exact pathological mechanism for scar formation remains unclear,leading to a lack of radical treatment.Recently,laser treatment has gained popularity as a new minimally invasive approach for scar treatment.The emergence of new theories such as fractional,picosecond laser,and laser-assisted drug delivery has led to continuous advance in laser treatment.Up to now,it has been developed numerous novel treatments,including combined with drug,physical,and other treatments,which have shown superior therapeutic effects.In order to optimize laser treatment in the future,it is crucial to combine new materials with postoperative care.This will help clinicians develop more comprehensive treatment strategies.Therefore,it is important to explore treatment options that have broader applicability.
