Objective To investigate the effect of Xing-Zhi-Yi-Nao (XZYN) particles on the expressions of Nogo and OMgp proteins in brain of rats after acute carbon monoxide (CO) poisoning.Methods A total of 120 Sprague-Dawley rats were randomly divided into normal group,CO poisoning group and XZYN particles treatment group (40 rats in each group).The rats in CO poisoning group and treatment group of acute CO poisoning were established by using an animal chamber,and then received hyperbaric oxygen therapy.Meanwhile,rats in treatment group were further given additional XZYN particles twice a day by gavage.At 1 day,1 week,1 month and 2 months after CO poisoning,the neurobehavioral score of rats was evaluated by a Morris water maze test and a shuttle box test,and the expressions of neurite outgrowth inhibitor (Nogo) and oligodendrocyte-myelin glycoprotein (OMgp) were investigated in rat brain tissue by immunohistochemistry staining and western blotting assay,respectively.Results Compared with those in normal control group((11.6±8.4)s,(41.8±4.4)%,(16.1±2.3)s,and (1.2±0.2)s),the escape latency in CO group was significantly prolonged ((14.1±6.1)s),and the T1/ T total was obviously decreased (23.6±2.4) %,the escape time ((26.3±3.8)s),the active escape latency ((2.3±0.3)s) were notably extended at 1 d (P<0.05).The cognitive dysfunction caused by CO poisoning was more obvious in the later stage of poisoning (from 1 week to 2 months,P<0.05).Compared with those in CO group,the escape latency was significantly shortened (from (3.5±0.6)s to (3.1±0.5)s),the T1/ T total was gradually increased (from (29.7±3.2)% to (36.7±3.2)%),the escape time (from (39.7±5.4)s to (18.1±2.0)s) and the active escape latency were obviously decreased (from (4.3±0.4)s to (2.1±0.2)s) in the later stage (>1 week) in Xing-Zhi-Yi-Nao treatment group (P<0.05).The expressions of Nogo and Omgp proteins in brain tissue in CO poisoning group were gradually increased as time went by.The increased expressions of Nogo and Omgp proteins were still observed at 1 month after CO poisoning.By contrast,XZYN particles could significantly improve cognitive function,reduce the expression of Nogo protein,and there was statistical difference compared with the poisoning group (P<0.05).However,the level of Omgp protein in XZYN treatment group was slightly lower than that in CO poisoning group,but there was no difference between the two groups (P>0.05).Conclusion The expression of Nogo and Omgp proteins may be associated with brain injury and demyelination in rats induced by CO poisoning.XZYN particles can down-regulate the expression of Nogo,and pave a way for the treatment of acute brain damage and delayed encephalopathy after CO poisoning.

Objective To explore the effect of individualized chemotherapy plans which was designed depend on secific genetic characters in patients with advanced cancer.Methods The surgery or biopsy specimen samples from 25 patients with advanced recurrent tumors (study group) were analyzed.Different gene mRNA expressions were detected by PCR and sequencing.According to detection results,the most appropriate chemotherapy would be applied on 25 cases patients of study group.The chemotherapy from traditional experience and evidence-based medical evidence were applied for 20 cases patients of control group.The difference of RR and disease control rate (DCR) between two groups were compared.Results The DCR and RR were 84 ％ (21/25) and 44 ％ (11/25) in study group,35 ％ (7/20) and 15 ％ (3/20) in control group.The DCR and RR in study group were significantly higher than those in control group (P ＜ 0.01).Conclusion Individualized chemotherapy could improve the efficient and prolong the survival period of the patients with advanced recurrent tumors.

ObjectiveTo explore the effect of community based rehabilitation on chronic schizophrenia. Methods60 patients of chronic schizophrenia were randomly divided into the community based rehabilitation group (the study group) and the inpatients group (the control group). The study used prospective design for 1 year with brief psychiatric rating scale (BPRS),nurses' observation scale for inpatients evaluation (NOSIE) and social disability screening schedule (SDSS).ResultsCompared with the control group at the end of 6 month and 1 year, scores of BPRS, NOSIE and SDSS in the study group were significantly different (P<0.05-P<0.001). The relapse rate of the study group (0%) also lowered than that of the control group( 20%).ConclusionsCommunity based rehabilitation therapy can control the chronic schizophrenia effectively. It also promotes the life quality and social function of patients, and lowers the relapse rate significantly. It is an important rehabilitation method for chronic schizophrenia.

Objective To evaluate the efficacy and safety of terlipressin for septic shock.Methods A randomized double-blind placebo-controlled pilot study was carried out in the general ICU of the First Affiliated Hospital of Zhengzhou University from June 1st 2015 to May 31st 2016.The septic shock patients with a mean arterial pressure below 65 mmHg despite adequate volume resuscitation were enrolled.Patients were randomized (random number) to give continuous infusions of either terlipressin[0.6-2.6 μg/(kg·h)] or norepinephrine(7-30 μg/min).Open label norepinephrine or other catecholamines were additionally infused if the mean arterial pressure failed to reach 65 mmHg.Treatment was continued until shock corrected,death or withdrawn from this study.Correcting rate of shock was the primary end point,the secondary end points included open labeled norepinephrine requirements,the 28 d survival rate and adverse events.The quantitative data of the two groups were compared by t test or Wilcoxon rank sum test.The enumeration data were compared by chi square test or Fisher exact probability method,and the survival data were analyzed by Kaplan-Meier method.Results A total of 28 patients were enrolled.The full analysis set was 28,the per-protocol set was 25,and the safety set was 28.The key demographics and baseline characteristics were similar between the two groups(P＞0.05).The results for the per-protocol set were followed up.The correcting rate of shock between the two groups were similar at the end of treatment[81.82％(9/11)vs.57.14％(8/14),P=0.190].The open label norepinephrine requirements of the trial group and control group for the 0,6,12,24,48 h time point were 0.661,0.921,1.583,1.241,2.143,1.371,1.071,1.261,0.370,1.001 μg/(kg·min),respectively with no significant difference(P＞0.05).The 28 d survival rate of the trial group and control group were 63.64％(7/11)and 50.00％(7/14) respectively with no statistical significance(P＞0.05).There was no significant difference in 28 d survival analyzed using Kaplan-Meier plot between two groups(P=0.470).There were two patients with ischemia of fingers,one patient with hyponatraemia and one patient with ischemia of intestine accompanied by hyponatraemia occurred after treatment with terlipressin,and one patient with isehemia of fingers occurred after treatment with norepinephrine.The incidence of adverse event for the trial group and control group were 30.77％(4/13) and 6.67％(1/15) with no significant difference(P=0.122).Conclusions Terlipressin is an effective agent for treating septic shock.The total adverse event rate of terlipressin was similar to that ofnorepinephrine.
