Objective To observe the influence of environment stimulation on learning and memory ability and hippocampal pathology of neonatal rats with hypoxic-ischemic brain damage (HIBD).Methods The models of HIBD SD rats were established by the method of Rice, and were divided randomly into three groups: enriched environment stimulation group (EE), impoverished environment stimulation group (IE), and standard environment stimulation group (SE). The sham-operation rats were served as control group. Different environment stimulation was administrated to the rats since day 1 after HIBD.On the day 28,Morris water maze was used to evaluate the learning and memory ability. HE staining and nissl stain were employed to observe the pathological change and the number of neurons in hippocampus of rats.Results The learning and memory ability of EE group was significantly higher than that of SE group (P0.05), and the ability of SE group was higher than that of IE group ( P0.05). The number of SE group was lower than that of Sham group (P

Objective To investigate parenteral nutrition and enteral nutrition therapy for esophageal cancer patients nutritional status improvement.Methods Totally 63 patients with esophageal cancer were chosen,preoperative Nutritional Risk Screening 2002 (NRS2002) nutritional screening through joint after parenteral nutrition and enteral nutrition therapy.Patients with intestinal tolerability and complications after surgery on days 1 and 7 days nutrition indicators were observed,including total serum protein,albumin,prealbumin,hemoglobin,and lymphocyte count.Results Preoperative risk malnutrition occurred in 39 patients.Compared to patients on day 1 after the first 7 days,serum levels had no significant difference in total protein.Albumin,prealbumin,hemoglobin,and lymphocyte counts were significantly different statistical significance (P ＜ 0.05).Conclusions NRS2002 for nutritional screening patients at risk of malnutrition can be determined,and the combined parenteral and enteral nutrition therapies can improve nutritional status of patients with esophageal cancer.

Objective To discuss the impact on nursing ward rounds with doctor in psychiatric clinical practice.Methods Since 2005,our hospital has carried out the nursing ward rounds with doctor,it has compared with the three aspects of patient satisfaction,accidents,complaints of patients or their families foreand-aft.Results Patient satisfaction was improved(χ2=85.369,P=0.000),and varioustypes accidents and complaints dropped after the nursing ward rounds with doctor.Conclusions Nursing ward rounds with doctor promoted establishing"communication-collaboration-complement"relationship between nurses and doctors,improved patient satisfactions,reduced accidents,improved self-sense of worth of nurses.

Objective Overexpressions of epidermal growth factor(EGF)and EGF receptor have been associ- ated with progression and invasive phenotype of pancreatic cancer.However,the underlying molecular mechanism by which EGF worked in pancreatic cancer cells has not been completely understood.In this study,effect of EGF on the invasion and metastasis of pancreatic cancer cells and its regulatory mechanism were investigated.Methods The effects of EGF on the proliferation,adhesion and invasion of pancreatic cancer cells were detected by WST-1 prolif- eration assay,adhesion assay and invasive assay,respectively.The activity and expression of MMP-2 and MMP-9 were examined by zymography,Western blot and RT-PCR,respectively.The activity of NF-?B was examined by EMSA.Results EGF could significantly promote the invasiveness of pancreatic cancer cells but did not affect cell proliferation or adhesion.The expressions of NF-?B and MMP-9 were significantly increased by EGF,but EGF did not affect the activity and expression of MMP-2.Furthermore,EGF stimulated the NF-?B binding activity.Pre- treatment with NF-?B inhibitors,pyrrolidine dithiocarbamate(PDTC),could significantly inhibit the activity of NF-?B induced by EGF.Meanwhile,the EGF-induced expression and activity of MMP-9,as well as cell invasiveness were also inhibited by NF-?B inhibitor.Conclusion EGF could increase the expression and promote the invasiveness of MMP-9 via the activation of NF-?B in pancreatic cancer cells,which implies that NF-?B inhibitant,such as PDTC,may diminish the invasiveness of pancreatic cancer cells.

Objective To investigate the changes and clinical significance of plasma N‐terminal pro‐brain natriuretic peptide (Nt‐proBNP) in patients with asphyxia of newborns combined with myocardial injury .Methods Fifty‐eight term neonates with neonatal asphyxia born within 24 h were included in our study ,18 of the 25 severe asphyxia cases were combined with myocardial injury ,15 of 33 mild asphyxia cases were with myocardial injury ,there were 25 subjects were not cardiac injured after asphyxia to‐tally .Patients of the same age without asphyxia or any cardiovascular disease were recruited into the control group .Levels of plasma Nt‐proBNP and creatine kinase isoenzyme (CK‐MB) were detected on the first ,third and the fifth days after birth for statistical a‐nalysis .Results On the first and third days after birth ,levels of plasma Nt‐proBNP in severe and mild asphyxia combined with my‐ocardial injury group were significantly higher than the groups without myocardial injury and the control (P<0 .05) .Levels of plas‐ma Nt‐proBNP in severe asphyxia myocardial injured group were significantly higher than those of the mild asphyxia myocardial in‐jured ones (P<0 .05) .On the fifth day ,the levels of plasma Nt‐proBNP in severe asphyxia myocardial injured group were signifi‐cantly higher than others (P<0 .05) .There was no difference in Nt‐proBNP levels between mild asphyxia myocardial injured group and the ones without myocardial injury (P>0 .05) .On the first day after birth ,levels of Nt‐proBNP ,CK‐MB were positively corre‐lated in the mild asphyxia group (r=0 .58 ,P<0 .05) and severe asphyxia group (r=0 .47 ,P<0 .05) .On the first day after birth , the cutoff value for myocardial injury was 695 .87 fmol/mL ,the area under the ROC curve was 0 .763 ,with the sensitivity of 71 .9%and specificity of 65 .4% ,the positive predictive value was 73 .3% and negative predictive value was 63 .8% .Conclusion The Nt‐proBNP level has important clinical value for early evaluation of the severity of myocardial injury after asphyxia .

OBJECTIVETo observe the clinical efficacy of Shugan Yiyang Capsules in the treatment of asthenospermia and its action mechanisms.

METHODSWe randomly assigned 135 asthenospermia patients to groups A (n = 47), B (n = 45), and C (n = 43) to be treated with Shugan Yiyang Capsules, oral levocarnitine, or combination of the two. We observed sperm quality and the level of α-glucosidase in the seminal plasma before and after medication.

RESULTSThe total effectiveness rate was 70.21% in group A (markedly effective in 16 cases and effective in 17), 68.89% in group B (markedly effective in 15 cases and effective in 16), and 83.72% in group C (markedly effective in 16 cases and effective in 20), significantly higher in C than in A and B (P < 0.05). Both sperm quality and the level of α-glucosidase in the seminal plasma were improved in the three groups of patients, most obviously in group C.

CONCLUSIONShugan Yiyang Capsules can be used for the treatment of asthenospermia, and its effect can be enhanced in combination with oral levocarnitine.
