Objective To evaluate the efficacy and toxicity of docetaxel combined with Cisplatin(DDP) and 5-fluorouracil(5-Fu) in the treatment of advanced gastric cancer. Methods 35 patients with advanced gastric cancer,which were confirmed by pathological diagnosis,were treated with docetaxel + DDP +5-Fu regimen:docetaxel 70 mg/m2 iv infusion for 4 hours on day 1, DDP 20 mg/m2 iv infusion on day 1 to 5,5-Fu 750 mg/m2 iv infusion for 6 hours on day 1 to 5 every 3 ～ 4weeks. Patients responsing to the chemotherapy finished at least 4 ～ 6 cycles or proceeded the therapy until progression of the disease (PD). Results 32 cases (91.4% ) were available for response evaluation with CR0;PR 15;SD7;PD 10. The rate of total remission( CR + PR) was 46.9% (15/32) ,and rates of CR and SD were 0 and 21.9% respectively. Leucopenia was seen in 40% patients,in which 13.6% cases were in grade III -IV. One patient had fever with neutropenia and improved after active treatment. There was no systemic infection or therapy-related death in all patients. Conclusion Docetaxel + DDP +5-Fu regimen has an assured response for advanced gastric cancer with tolerable toxicity and could be an effective candidate in clinical treatment.

Objective To explore the expressions of autophagy-related gene Beclin-1 and LC3 in adriamycin induced eardiomyopathy rats,to prnve that autophagy might take part in the development of adriamycin induced eardiomyopathy in rats,so as to provide experimental and theoretical evidence for preventing and treating adriamycin induced cardiomyopathy.Methods Forty-five male SD rats were randomly divided into 3 groups,control groups,ADR group and ADR+3-MA group.The model of adriamycin induced cardiomyopathy rats was established.The tissue sample taken from the left ventricle wall was checked for the morphons of autophagosome by electron microscope. The expressions of Beelin-1 and LC3 of myocardium were detected.Results The morphons of autophagosome in ADR group was significantly increased compared with that in control and ADR +3-MA groups. The expression of Beclin-1 in myocardium of ADR group was significantly inereased compared with that in control and ADR +3-MA groups (P < 0.05).The level of LC3 in myocardium of ADR group was significantly increased compared with that in control and ADR+3-MA groups (P < 0.05).Conclusions Autophagy plays an important role in adriamycin induced cardiomyopathy.

Aim To determine whether pranlukast (ONO-1078), a cysteinyl leukotriene receptor antagonist, possesses therapeutic effect when administered after focal cerebral ischemia in mice. Methods Persistent focal cerebral ischemia was induced by middle cerebral artery occlusion. Pranlukast and edaravone, a positive control drug, were ip injected 1, 6 and 24 h after ischemia. The neurological deficits were evaluated by neurological scores and inclined plane test 24 and 48 h after the surgery. Forty-eight h later, the brain slices were prepared for measurements of infarct volume and the ratio of ischemic/non-ischemic hemispheres. Brain sections were cut and examined for neuron densities in different regions of the brain. The effects of pranlukast and edaravone were evaluated by the changes of these variables. Results Pranlukast (0.1 and 0.2 mg?kg -1) and edaravone (3 and 10 mg?kg -1) significantly reduced the neurological deficits, infarct volume (maximally 82.3%), ratio of ischemic/non-ischemic hemispheres, and attenuated the reduction of neuron densities in hippocampal CA1 region, cortex and striatum. Conclusion Pranlukast possesses therapeutic effect on ischemic insults when administered after ischemia as effective as edravone, indicating a therapeutic potential in the treatment of ischemic stroke.

AIM:To confirm the action of the light transmission method in evaluating focal ischemic cerebral infarction on persistent focal cerebral ischemia in mice. METHODS:Persistent focal cerebral ischemia was induced by middle cerebral artery occlusion (MCAO). Bederson's neurological scores, climbing board and hanging test were performed 24 h after ischemia, and infarct volume, brain hemisphere area, neuron density of cortex and subcortex were measured with computer-assisted imaging. Pranlukast ( 0.1 mg?kg -1) or nimodipine ( 0.4 mg?kg -1) were injected ip once daily for 3 days and to 1 h before MCAO assess the neuroprotective effect. RESULTS:The infarct volumes measured by light transmission closely correlated with that measured by TTC staining and neuron densities. The infarct volumes measured by light transmission well correlated with the neurological scores measured by integrated graded approach, too. Both pranlukast and nimodipine significantly attenuated infarct volumes and the ratio of ischemic/non-ischemic hemispheres, and reduced neurological deficits and neuron death. CONCLUSION:Light transmission and integrated graded approach can be used not only for qualitative analysis of focal cerebral ischemia, but also for evaluating the neuroprotective effect of drugs.

Based on the development trends of nursing care in the ongoing healthcare reform, the PEST model was called into play to analyze the macro-environment of nursing development in terms of such aspects as political, economic, social-cultural, and science and technology factors. Based on such, policy suggestions are raised to tackle the following challenges, namely incomplete political and legal environment for nursing, relative shortage of nursing resources, low social recognition, and poor capability of nursing technique innovation. These suggestions aim to further improve the political and legal system for nursing, explore highly efficient nursing resource allocation, enhance nursing service capability, and nurture nursing technique innovation talents.

Objective:To study the role of myocardial work parameters in early identification of myocardial injury in neonatal asphyxia.Methods:From July 2020 to December 2021, neonates diagnosed with mild neonatal asphyxia admitted to the Department of Neonatology of our hospital within 24 h after birth were prospectively enrolled into the asphyxia group. Neonates without asphyxia during the same period were selected as the control group and matched with the asphyxia group for gender, gestational age and birth weight at a ratio of 1:1~1:2. The asphyxia group was subgrouped into preterm asphyxia group and term asphyxia group. All neonates received echocardiography within 24 h after birth. Multiple parameters were measured including M-mode, two-dimensional image, Doppler image, global longitudinal strain (GLS) and myocardial work parameters [global work index (GWI), global constructive work (GCW), global wasted work (GWW), global work efficiency (GWE)]. The level of serum N-terminal pro brain natriuretic peptide (NT-proBNP) was recorded in the asphyxia group. The data were compared between the asphyxia group and the control group. Correlations between myocardial work parameters and other parameters were analyzed.Results:A total of 33 cases were in the asphyxia group and 43 cases were in the control group. The preterm asphyxia group (18 cases) showed significantly lower GWI and GCW than the preterm control group (18 cases) [GWI: (702±153) mmHg vs. (879±205) mmHg, GCW: (1 016±221) mmHg vs. (1 200±271) mmHg] ( P<0.05). No differences existed in GLS, GWW and GWE. The term asphyxia group (15 cases) showed significantly lower GWW than the term control group (25 cases) [45.0 (30.0, 65.0) mmHg vs. 71.0 (35.5,85.5) mmHg] ( P<0.05). No differences existed in GLS, GWI, GCW and GWE. GWI was negatively correlated with serum NT-proBNP level ( r=-0.327, P<0.05). Conclusions:GWI and GCW may indicate myocardial injury in preterm neonates with mild asphyxia.

Purpose To use two-dimensional speckle tracking imaging(2D-STI)to evaluate left ventricular myocardial strain in term and preterm neonates.Materials and Methods A total of 81 neonates who accepted echocardiography in Soochow University Affiliated Children's Hospital from February to August 2018 were retrospectively enrolled,including 42 term neonates and 39 preterm neonates.Longitudinal and circumferential peak strain of each segment of left ventricle were measured by 2D-STI,and the average global longitudinal peak strain(GLPS-avg)and the average global circumferential peak strain(GCPS-avg)of left ventricular were measured too.Left ventricular ejection fraction(LVEF-M,LVEF-Simpson),short-axis shortening rate(LVFS-M),left ventricular end-diastolic diameter(LVEDD),and tissue Doppler imaging parameters(E',A' and E'/A')of the septal mitral annulus were also measured.The differences in each segment of left ventricle and echocardiography between term neonates and preterm neonate were further compared.Results There were statistically significant differences in GLPS-avg,the global longitudinal peak strain from the apical two-chamber view(GLPS-a2c),GCPS-avg and the global circumferential peak strain in the middle and apical segments(GCPS-M ang GCPS-A)(t=-3.60--2.18,all P<0.05)between term neonates and preterm neonates,while there were no significant differences between the global longitudinal peak strain from the apical four-chamber and three-chamber view(GLPS-a4c and GLPS-a3c),the global circumferential peak strain in the basal segments(GCPS-M)(all P>0.05).There were statistically significant differences in GLPS-a4c,GLPS-a2c,GLPS-a3c in preterm neonates group(F=3.20,P=0.044),and the strain value GLPS-a4c was the highest.There were statistically significant differences in GCPS-B,GCPS-M,GCPS-A in preterm neonates group(F=79.15,P<0.001).There were statistically significant differences in GCPS-B,GCPS-M,GCPS-A in term neonates group(F=97.95,P<0.001),and the strain value increased from the basal segment to the apical segments.There was statistically significant difference in LVEDD between term neonates and preterm neonates(all P<0.05).There were no statistically significant differences in LVEF-M,LVEF-Simpson,LVFS-M,E',A' and E'/A' between term neonates and preterm neonates(all P>0.05).Conclusion 2D-STI may be a useful method of measuring left ventricular myocardial systolic function and can provide early detection of differences in left ventricular myocardial contraction between term and preterm neonates.
