Objective:To evaluate the effect of remote ischemic conditioning (RIC) on left ventricular (LV) myocardial perfusion, myocardial viability, LV remodeling, regional and global LV function serially following acute myocardial infarction (AMI) in Chinese mini-pigs.Methods:AMI was established in 12 Chinese mini-pigs (8 males, 4 females; age: 6-8 months) and they were randomly divided into RIC group ( n=6) and non-RIC group ( n=6). RIC was performed in pigs by blood pressure inflation on the lower limbs for 5 min period and 4 cycles immediately after surgery. A series of myocardial perfusion imaging and gated 18F-fluorodeoxyglucose (FDG) myocardial metabolism PET/CT imaging were performed longitudinally at the 1st, 14th, 28th and 56th days after AMI, and parameters including total perfusion defect (TPD), hibernating myocardium (HM), Scar, left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), summed motion score (SMS), summed thickening score (STS) and changes of these parameters were obtained. Independent-samples t test and Mann-Whitney U test were used to analyze data. Results:Nine Chinese mini-pigs survived after surgery and were performed imaging. Compared to non-RIC group ( n=4), HM at the 28th ((6.0±2.4)% vs (17.0±4.6)%; t=-4.158), TPD 14th-1st ((-11.8±5.4)% vs 9.0%(4.5%, 15.0%); z=2.449), TPD 28th-1st ((-15.3±3.9)% vs (12.0±3.0)%; t=-10.071), TPD 56th-1st ((-18.0±6.5)% vs 9.0%(4.5%, 12.0%); z=2.449), HM 28th-1st ((-10.5±6.9)% vs (8.3±2.1)%; t=-4.507), HM 56th-1st (-15.0%(-17.5%, -8.5%) vs 2.0%(0%, 7.0%); z=2.449) and LVEDV 14th-1st (-0.5(-2.5, 0) ml vs (13.0±4.4) ml; z=2.470) were reduced in RIC group ( n=5; all P<0.05). Conclusion:RIC can improve myocardial perfusion, delay LV remodeling in the acute stage and salvage hibernating myocardium in the subacute stage and chronic stage.

Objective To investigate the effect of sub-anesthesia dose of isoflurane in 60％ oxygen on acute lung injury in aged rats with sepsis.Methods Ninety male Sprague-Dawley rats,aged 12-14 months,weighing 500-800 g,were divided into 3 groups (n=30 each) using a random number table:sham operation group (Sham group),sepsis group (S group),and sepsis plus isoflurane plus oxygen treatment group (S+I+O group).Sepsis was induced by cecal ligation and puncture in S and S+I+O groups.In group S+I+O,0.7％ isoflurane in 60％ oxygen was inhaled for 1 h starting from 1 and 6 h after operation.Eighteen rats were selected in each group and observed for 7 days after operation,and the survival rate was recorded.Six rats were selected in each group at 24 h after operation,and bronchoalveolar lavage fluid (BALF) was collected to determine the protein concentrations (by BCA protein assay),blood samples were collected from the femoral artery for blood gas analysis,PaO2 was recorded,and the oxygenation index was calculated.Six rats in each group were sacrificed at 24 h after operation,the left lung specimens were obtained and stained with hematoxylin and eosin for examination of pathological changes,the right lung specimens were obtained for determination of wet to dry weight ratio (W/D ratio),and blood samples were collected from the right atrium for measurement of the concentrations of interleukin-1β (IL-1β),IL-6,tumor necrosis factor-α (TNF-α),high-mobility group box 1 protein (HMGB1) and IL-10 in serum (by enzyme-linked immunosorbent assay).Results Compared with group Sham,the survival rate was significantly decreased,and the concentrations of IL-1β,IL-6,TNF-α,HMGB1 and IL-10 in serum were increased in S and S+I+O groups,and W/D ratio and protein concentrations in BALF were significantly increased,and the oxygenation index was decreased in group S (P＜0.05).Compared with group S,the survival rate was significantly increased,W/D ratio and protein concentrations in BALF were decreased,the oxygenation index was increased,the concentrations of IL-1β,IL-6,TNF-α and HMGB1 in serum were decreased,and the concentration of serum IL-10 was increased (P＜0.05),and the pathological changes were significantly attenuated in group S+I+O.Conclusion Sub-anesthesia dose of isoflurane in 60％ oxygen can reduce acute lung injury in aged rats with sepsis,and the mechanism may be ralated to inhibiting systemic inflammatory responses.

Despite its more than 100-year history in experimental and clinical use, photodynamic therapy (PDT) is only starting to be appreciated for its full potential. PDT combines a photosensitizer and light in the presence of oxygen to treat cancer and other disorders. This paper reviews the molecular mechanism of PDT at the cellular level as well as in therapeutic settings in vivo. The availability of multiple photosensitizers with different structures and functional properties makes PDT an extremely versatile and, conversely, a challenging approach to cancer therapy. The advancing understanding of molecular pathways helps to design improved regimens. As most cancers are being treated with combined therapies, PDT is being integrated into rationally designed regimens that exploit molecular responses to PDT for improved efficacy.

Objective: Victims with shock-able initial arrest rhythms (ventricular fibrillation or pulse-less ventricular tachycardia, VF/VT) have much better outcomes from out-of-hospital cardiac arrest (OHCA) than those with non-shock-able initial rhythms (pulse-less electrical activities, PEA or asystole). Prompt defibrillation is believed pivotal to terminate lethal shock-able arrest rhythms. In this study, we were to identify those pre-hospital epidemiological factors which were associated with likelihood of shock-able rhythms first recorded when out-of-hospital cardiac arrest occurred. Methods: A multicenter, secondary, retrospective and observational analysis was performed on all adult non-traumatic OHCA in the Resuscitation Outcome Consortium (ROC) PRIMED study from June 2007 through November 2009. Of a total of 17 177 OHCA cases in PRIMED study, 13 421 of them were enrolled in this study when those OHCA patients with DNR order, or initial rhythms unknown, or arrest caused by obvious cause were excluded. We reported their demographics and episode characteristics for all enrolled cases. Multivariable logistic regression was employed to identify factors which were associated with likelihood of VF/VT recorded as shock-able initial rhythms. Results: Among 13 421 adult non-traumatic OHCA cases with initial rhythms recorded, 3 527 (26.3%) of them had shock-able rhythms, while 9 894 (73.7%) patients were in non-shock-able rhythms. Of the OHCA with shock-able arrest rhythms, 1 850(52.5%) obtained return of spontaneous circulation (ROSC) in the field, while 912 (25.9%) survived to hospital discharge. On the other hand, 2489(25.2%) of the OHCA with non-shock-able arrest rhythms obtained ROSC in the field, while 325 (3.3%) of them survived to hospital discharge. Multivariable regression analysis revealed those factors which indicated likelihood of shock-able rhythms recorded were: age(OR: 0.991,95%CI 0.988-0.993), male gender (OR1.887,95%CI1.718-2.073), pre-hospital Emergency Medical System(EMS) response time(OR0.950,95%CI 0.931-0.970), cardiac arrest witnessed by EMS providers(OR1.709,95%CI 1.423-2.054) or bystander(OR3.199,95%CI 2.921-3.504) and those with bystanders CPR (OR1.357,95%CI 1.239-1.487),public place of cardiac arrest (OR2.705,95%CI 2.437-3.003). Conclusions Some demographics and pre-hospital characteristics were proved associated with likelihood of shock-able arrest rhythms first recorded in OHCA victims, which might help develop corresponding strategies to deliver prompt shock on initially shock-able patients and improve their outcomes.

Objective To investigate the efficacy of sakubatril valsartan combined with tolvaptan in the treatment of heart failure patients with reduced ejection fraction(HFrEF)and the effects on echocardiography and cardiovascular events.Methods According to the random number table method,400 patients with HFrEF admitted to the First People's Hospital from September 2017 to January 2022 were divided into the control group and the combination group with 200 cases each.Both groups were given conventional treatment,based on which the control group was given sacubitril valsartan and the combination group was given sacubitril valsartan combined with tolvaptan.The efficacy,echocardiographic indexes[left ventricular ejection fraction(LVEF),left ventricular end-diastolic internal diameter(LVEDD),left ventricular end-systolic internal diameter(LVESD)],myocardial injury indexes[serum brain natriuretic peptide(BNP),high-sensitivity troponin T(hs-CTnT),growth transforming factor-15(GDF-15)],urine output,neuroendocrine factors[antidiuretic hormone(ADH),angiotensin(PRA),angiotensin Ⅱ(Ang Ⅱ)],cardiovascular events and adverse effects were compared between the two groups.Results The total effective rate was 94.50%(189/200)higher in the combined group than 86.00%(172/200)in the control group(P＜0.05);LVEF was high-er in the combined group than in the control group after treatment,and LVEDD and LVESD were lower than in the control group(P＜0.05);BNP,hs-CTnT,GDF-15,ADH PRA,and Ang II were lower in the combined group than in the control group,and urine volume was higher than in the control group(P＜0.05);at 6-month follow-up after treatment,there were no statistically significant differences in the rehospitalization rate of heart failure,the incidence of non-fatal infarction,post-discharge cardiovascular mortali-ty and all-cause mortality in the combined group compared with those of the control group(P＞0.05);there were no statistically significant differences in the incidence of adverse events in the combined group compared with that of the control group(P＞0.05).Conclusion Sacubitril valsartan combined with tolvaptan is effective in treating HFrEF,by reducing myocardial inju-ry,promoting urination,and improving patients'cardiac function without increasing the risk of cardiovascular events and adverse reactions.

Poly ADP-ribose polymerase-1 (PARP-1) plays a vital role in organisms, including regulating repair of DNA, maintaining genome stability, regulating cell proliferation, differentiation, and death.At present, PARP inhibitors have been made some breakthrough in the treatment of breast cancer, ovarian cancer, prostate cancer and pancreatic cancer.However, PARP inhibitors have certain limitations in other malignant tumors and patients who are resistant to PARP-1 inhibitors.This article summarizes the research on PARP inhibitors in lung cancer, hepatocellular carcinoma, glioblastoma, leukemia and cervical cancer, and introduces the strategies of combining other anti-tumor drugs such as DNA repair inhibitors, immune checkpoint inhibitors, anti-angiogenic drugs and other chemotherapeutic drugs to solve their drug resistance, which provides some reference for the wide clinical application of PARP inhibitors in the future.
