Objective To study the effect of Alemtuzumab on acute rejection (AR) and graft survival after kidney transplantation.Method Published domestic and foreign literatures regarding the effects of Alemtuzumab used on acute rejection and graft survival were reviewed,and Meta analysis was employed to analyze the Results.Odds ratio (OR) and its 95％ confidence interval (95％ CI) were used as the parameters to evaluate the therapeutic effects.The statistical analyses were performed with RevMan 5.1 software.Result A total of 9 pertinent research articles were reviewed.Meta-analysis of pooled results indicated that Alemtuzumab prevented the recipients of kidney transplantation from acute rejection effectively with half year prevention of OR 0.37 and 95％ CI 0.24-0.58 (P＜0.01),one year prevention of OR 0.43 and 95 ％ CI 0.29-0.64 (P＜0.01),and two year prevention of OR 0.69 and 95％ CI 0.47-1.02 (P ＜ 0.01),respectively.It was revealed that Alemtuzumab could reduce the incidence of acute rejection by 55％ in half year,51％ in one year and 28％ in two years,respectively.No statistically significant difference in graft survival was found between Alemtuzumab group and control group (OR =1.18,95％ CI 0.76-1.85,P =0.46).No statistically significant difference in patients' survival was found between Alemtuzumab group and control group (OR =0.94,95 ％ CI 0.52-1.72,P =0.85).Conclusion Alemtuzumab may effectively prevent the recipients of kidney transplantation from acute rejection,but not obviously influence the graft and patient survival.

Objective To study influence of tongxinluo on blood endothelial microparticles(EM Ps) and matrix metalloprotei‐nase‐9(MMP‐9) in patients with acute myocardial infarction after percutaneous coronary intervention(PCI) .Methods One hundred and twenty‐eight hospitalized patients with acute myocardial infarction after per‐cutaneous coronary intervention were recruited from January 2012 to December 2014 ,All patients were randomly divided into tongxinluo group (n=65) and control group (con‐ventional treatment ,n=63) .Tongxinluo group was on the basis of conventional treatment group with tongxinluo capsules 2 plus ,3 times a day .We detected the EMPs and MMP‐9 of two groups preoperatively and on the 7th postoperatively day .Results Com‐pared with the conventional treatment group ,blood EMPs and MMP‐9 in tongxinluo group were lower after 7 days treatment ,the difference was statistically significant (P<0 .05) .There was a positive correlation between the EMPs and MMP‐9(P<0 .05) .Con‐clusion For patients with acute myocardial infarction after percu‐taneous coronary intervention ,tongxinluo could further inhibit in‐flammatory reaction ,make the plaque stability and improve the function of endothelial cells on the basis of conventional treatment groups .

Objective To examine the effect of modified electroconvulsive therapy (MECT) on the plasma oxida-tive stress level in bipolar depression. Methods Forty-two patients with bipolar depression were randomly divided into two groups. The intervention group (n=18) received antidepressants and 12 times MECT for 6 weeks and the control group (n=24) received antidepressants and Li2CO3 for 6 weeks. The Chinese versions of the 17 items Hamilton Depression Rating Scale (HAMD-17), Young Mania Rating Scale (YMRS), Clinical Global Impression Scale (CGI-S) and Treatment Emergent Symptom Scale (TESS) were used to assess participants at baseline and after 6 weeks of treatment. The plasma levels of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA)were detected at baseline and after 6 weeks to assess the level of oxidative stress. Results Repeated measures analysis of variance showed that the plasma level of SOD was higher in MECT group than in Li2CO3 group (F=15.26, P<0.01), and the level of MDA was higher in Li2CO3 group (F=18.18, P<0.01). The interactive effect of group and time was significant in GSH-Px level (F=6.39, P=0.02). The level of GSH-Px was lower in MECT group than in Li2CO3 group after 6 weeks (P<0.05). The CAT level was higher in the response patients than in non-response patients after 6 weeks (P<0.05). Con-clusions Both MECT treatment and Li2CO3 treatment can alter oxidative stress levels in patients with bipolar depression. The mechanisms underlying its therapeutic regimen may correct the imbalance of the plasma CAT level.

Objective To investigate the characteristics of auditory P300 amplitude and latency and cognition in patients with clinical high-risk of psychosis (CHR). Method Thirty six CHR (study group) and thirty five healthy con?trols (control group) were included. Oddball paradigm and MATRICS Consensus Cognitive Battery (MCCB) were used to record auditory P300 and to evaluate the cognition, respectively. The structured interview for psychosis-risk syndromes (SIPS) was used to evaluate the clinic symptoms of patients. Result The cognition of CHR was significantly lower than healthy controls in information processing, attention/vigilance, working memory, verbal learning, visual learning, reason?ing and problem solving and social cognition (P<0.01). The study group showed decreased amplitude in Fz, Cz and Pz and delayed latency in Pz (P<0.05). P300 latency of CHR in Fz positively correlated with positive score of SOPS (r=0.544, P=0.001), while P300 amplitude positively correlated with verbal fluency (r=0.339,P=0.043). Conclusion Cogni?tion and P300 is abnormal in CHR. The correlation between P300 and clinical symptoms, cognitive dysfunction reminds that we should put more attention on the role of P300 in CHR subjects.

Objective To explore the optimized method of venous anastomosis for right donor kidney transplantation in rats.Methods Sprague Dawley (SD) rats were used as donors and recipients for homologous rat kidney transplantation.Both bilateral kidneys were harvested from the donor rats (n =45).Ninety rats were used as recipients and divided into 4 groups according to randomly digital table:In groups AC (n =15 each),the right donor kidneys were transplanted into the left nephridial pit of recipients,and endto-side,venous bypass and modified end-toend (donor's proximal end of vena cava was anastomosed to recipients renal Vein followed by ligation of its distal end) venous anastomosis was done,respectively; In the control group (n =45),the left donor kidneys were transplanted into the same side of the recipients,and the conventional end-to-end venous anastomosis was used.Then the intra-operative findings,successful operation rate and postoperative complications were compared between two groups.Results The venous anastomosis time in group B was longer than in groups A,C and control group (P＜0.05),which significantly increased warm ischemia time of donor kidneys and operative time of recipients (P＜0.05).The venous anastomosis time,warm ischemia time of donor kidneys and operative time of recipients showed no significant difference between groups A or C and control group (P＞0.05).The successful operation rate in group C (93.3％)was similar to that in control group (86.7％) (P＞0.05),but higher than in group A (53.3％) and group B (53.3％) (P＜0.05).There was no significant difference in postoperative complications between group A and group C.Conclusion For right donor kidney transplantation,the method of harvesting the right donor kidney with a part of vena cava,and then anastomosing the proximal end to recipients renal vein and ligating the distal end,is highly feasible,efficient and economic.
