Objective:To observe influence of alprostadil injection on contrast-induced nephropathy (CIN) in high risk patients after percutaneous coronary intervention (PCI).Methods: A total of 263 CIN high risk (CIN risk score ≥16 scores) patients were selected.According to random number table, patients were randomly divided into routine treatment group (n=121, received routine hydration therapy) and alprostadil group (n=142, received additional alprostadil injection based on routine treatment group).Serum creatinine (SCr), glomerular filtration rate(GFR), cystatin C (CysC) and β trace protein (β-TP) level before, 48h and 72h after PCI were measured and compared, and incidence rate of CIN, percentage of blood purification therapy and mortality were compared between two groups.Results: Compared with before PCI, there was significant rise in SCr level and significant reduction in GFR in both groups on 48h and 72h after PCI (P<0.01 all);Compared with routine treatment group, there were significant reductions in levels of SCr [72h: (190.04±28.92) μmol/L vs.(141.10±21.18) μmol/L], and significant rise in GFR [72h: (26.0±4.4) ml/min vs.(36.4±4.9) ml/min], and levels of CysC[72h: (1.75±0.74) mg/L vs.(1.47±0.55) mg/L] and β-TP [72h: (1.53±0.50) mg/L vs.(1.22±0.38) mg/L] significantly decreased in alprostadil group on 48h and 72h after PCI, P<0.05 or <0.01;there were significant reductions in incidence rate of CIN (30.6% vs.18.3%) and percentage of blood purification therapy (10.7% vs.3.5%) in alprostadil group, P=0.001, 0.045 respectively.There was no significant difference in mortality between two groups, P=0.728.Conclusion: Alprostadil injection can significantly improve kidney function, reduce incidence rate of CIN and percentage of blood purification therapy in CIN high risk patients after PCI, which is worth extending.

Genomic instability is one of the most pervasive characteristics of cancer cells,and DNA damage response (DDR) pathway plays a crucial role in genomic stability.The DDR pathway is a complex signaling network,which involves cell DNA repair,apoptosis and cell cycle regulation.Deficiencies in these repair pathways can result in several different genetic disorders,including cancer.Targeted therapy based on inhibiting the DDR pathway in cancers offers a novel therapy strategy for patients with tumors lacking specific DDR functions.Many small-mole-cule compounds targeting DDR pathway are typically developed for solid cancer therapy.The poly (ADP-ribose) polymerase (PARP) inhibitor is a kind of DDR inhibitors which exploits the principle of synthetic lethality to selectively kill cancer cells.This review highlights the molecular mechanisms of PARP inhibitor action,the progress of PARP inhibitors in cancer therapy,drug resistance and the challenge of PARP inhibitor in the future.

Objective To evaluate early and dynamic changes of the left ventricular systolic function of patients with septic shock by two-dimensional speckle tracking imaging (2D-STI), and to provide guidance for treatment and prognosis.Methods Fifty-eight septic shock patients admitted to intensive care unit (ICU) of Subei People's Hospital from January 2016 to April 2017 were enrolled. The septic shock patients were given early fluid resuscitation. The left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), early diastolic mitral flow velocity/early diastolic mitral annular peak velocity (E/Em) were obtained by conventional echocardiography, and the left ventricular global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS) were obtained by 2D-STI before fluid resuscitation and 1, 3, 7, 14 days after fluid resuscitation. According to the 28-day survival, the septic shock patients were divided into survival group (38 cases) and death group (20 cases). Thirty normal subjects with age and sex matched were selected as control group.Results① Compared with control group, heart rate (HR) and LVESV were increased [HR (bpm): 92.71±12.51 vs. 73.07±5.52, LVESV (mL): 42.50±7.89 vs. 38.73±4.23, bothP < 0.05], while LVEF, GLS, GCS were decreased [LVEF: 0.57±0.06 vs. 0.61±0.03, GLS: (-17.72±1.35)% vs. (-22.07±1.95)%, GCS: (-17.08±1.49)% vs. (-22.98±1.97)%] in septic shock group (allP < 0.01). ② Compared with the data before fluid resuscitation, heart rate was declined (bpm: 87.83±11.50vs. 92.71±12.51,P < 0.01), while LVEDV and LVEF were increased [LVEDV (mL): 102.32±9.23 vs. 99.24±8.86, LVEF: 0.59±0.05 vs. 0.56±0.06] in patients of the septic shock after fluid resuscitation (allP <0.01). ③ With the extension of treatment time, HR, LVEDV, LVESV, E/Em were increased gradually, and LVEF, GLS, GCS, GRS were decreased gradually in dead patients. In septic shock patients, compared with survival group, GCS was significantly different on day 1 [(-15.98±1.41)% vs. (-17.66±1.22)%,P < 0.05], HR, LVEDV, LVESV, GLS were significantly different on the 3rd day [HR (bpm): 104.60±10.94 vs. 88.71±5.06, LVEDV (mL): 109.69±10.00 vs. 103.99±5.74, LVESV (mL): 47.78±7.21 vs. 42.29±5.13, GLS: (-14.44±0.92)% vs. (-16.36±1.00)%, allP < 0.05], LVEF, GRS were significantly different on the 7th day [LVEF: 0.47±0.07 vs. 0.58±0.04, GRS: (28.27±3.23)% vs. (31.48±3.12)%, bothP < 0.05], and E/Em was significantly different on the 14th day (12.81±1.56 vs. 10.61±1.27) in dead group (P < 0.05).Conclusions Our study demonstrates myocardial dysfunction at the early phase in septic shock patients, and 2D-STI GCS can be more sensitive than the conventional echocardiography to determine prognosis. 2D-STI GCS, GLS, GRS were not volume-load dependent parameter. Low levels of GLS, GCS might suggest a poor prognosis.
