Objective To explore the curative effect of modified closed negative pressure drainage on abnormal abdominal incision. Methods Sity-three patients with abnormal healing of abdominal incision in our hospital from January 2012 to June 2013 were selected as the observation group. Another 50 patients from January to December 2011 were assigned to the control group. The former was treated after debridement with human recombinant surface growth factor and modified closed negative pressure drainage,while the latter after debridement with anti-infection and dressings of ethacridine or gentamicinsolution as well as with infrared therapy. The two groups were compared in terms of the frequency,time and cost of changed dressings,and the healing time of the incisions.Results There was insignificant difference in the cost of changed dressings between the two groups(P>0.05). However,the differences were statistically significant in terms of the frequency and time of changed dressings and the healing time of the incisions(P<0.05). The observation group was significantly superior to the control group.Conclusions Modified closed negative pressure drainage is effective in accelerating the healing in abnormal abdominal incisions,reducing the frequency and the time of changed dressings,and easing the economic burdens of the patients,which is suggested to be popularized and applicable in the pimary hospitals.

Objective To investigate the effect of pregnancy on the potency of bupivacaine for spinal anesthesia in rats. Methods Female non-pregnant SD rats weighing 180-220 g and 17 day pregnant SD rats weighing 350-400 g were used in this study. The rats ( 18 non-pregnant, 18 pregnant) in which PE-10 catheter were successfully placed without complications were selected. The 18 non-pregnant rats were randomly divided into 3 groups (n =6 each): control group (group C), 2% bupivacaine group (group B2 ) and 4% bupivacaine group (group B4). The 18 pregnant rats were also randomly divided into 3 groups (n = 6 each): control group (group PC),2% bupivacaine group (group PB2 ) and 4% bupivacaine group (group PB4 ). Group C and PC received intrathecal (IT) normal saline 30 μl, and the other 4 groups received 2% or 4% bupivacaine 30 μl intrathecally. Analgesia was determined using the taifllick latency (TFL) before IT administration (baseline), and at 10 min, 20 min,30 min, 1 h, 2 h, 4 h, 1 d, 2 d, 3 d and 4 d after IT administtation. The percentage of the maximal possible effect (MPE) was calculated. Hind-limb motor function (MF) was also assessed. Results Compared with the baseline value, MPE at 10 min-2 h after administration and MF scores at 10 min-1 h after administration were significantly increased in group B2, MPE at 10 min-4 h after administration and MF scores at 10 min-1 h after administration were significantly increased in group B4;MPE at 10 min-1 d after administration and MF scores at 10 min2 h were significantly increased in group PB2 and MPE at 10 min-1 d after administration and MF scores at 10 min4 h were significantly increased in group PB4 ( P ＜ 0.05 ). Conclusion Pregnancy can enhance the potency of bupivacaine for spinal anesthesia in rats.

Objective To investigate immunogenicity and protection efficacy of the recombinant hypoxanthine-guanine-xanthine (HGXPRT) of Plasmodium falciparum expressed in Pichia pastoris. Methods 35 BALB/c mice were divided randomly into five groups: HGXPRT+ISA720 experiment group, HGXPRT+Freund experiment group, ISA720 adjuvant control group, Freund adjuvant control group, and blank control group. BALB/c mice were subcutaneously immunized three times with the HGXPRT protein formulated by either Freund or ISA720 adjuvants at a three weeks interval. Mice were bled via tail vein at 2 weeks after each immunization. Specific antibodies were detected by ELISA as well as IFAT using cultured parasites. The immunized mice were challenged with 105 P.yoelii 10 days after the third immunization and parasitemia was monitored daily by examining Giemsa-stained thin film. Results Strong immune response was induced by the HGXPRT antigen formulated with the adjuvant. Antibody titers of more than 1∶105 were detected after the third immunization while no specific antibody was detected in the mice immunized with adjuvants only. The antibodies against HGXPRT recognized the cultured parasite by IFAT. Four days after mice were challenged with P.yoelii, high parasitemia appeared in the two control groups, which were 24 h earlier than experiment groups. The mean parasitemia of HGXPRT+ISA720 experiment group(29.3%) was significantly lower than that of control groups (70.0%) (P

Objective To compare the difference of immune responses to hepatitis B virus (HBV) vaccine in human immunodeficiency virus (HIV)-1-infected patients with different CD4+ T-lymphocyte counts.Methods HIV-1-infected patients who visited clinic at the Public Health Clinical Center of Chengdu were enrolled and divided into two groups according to CD4+ T-lymphocytes counts.CD4+ T-lymphocytes ＜200/μL,which were and ≥200/μL.All patients were injected intramuscularly with 20 μg of HBV vaccine at month 0,1 and 6,respectively.Vaccination responses were measured at1 and 7 months after first dose.The serum anti-hepatitis B sarface antigen titers of ≥ 10 mIU/mL were considered positive.The serum anti-HBs positive rates was compared by Chi-square test and anti-HBs titers was compared by Mann-Whitney test.Results Ninety-five HIV-1-infected patients were finally enrolled into the analysis,with 55 patients in group of CD4+ T-lymphocytes ＜200/μL and 40 patients in group of CD4+ T-lymphocytes ≥200/μL.The serum anti-HBs positivity rates at 1 and 7 months after first dose in group of CD4+ T-lymphocytes ＜200/μL were 40.0％ (22/55) and 50.9％ (28/55),respectively,which were 47.5％ (19/40) and 75.0％ (30/40) in group of CD4+ Tlymphocytes ≥200/μL.There was no significant difference of serum anti-HBs positivity rates between two groups after 1 month (x2 =5.652,P=0.017).But a significant higher positivity rate was found in group of CD4+ T-lymphocytes ≥200/μL than in group ofCD4+ Tlymphocytes＜200/μL after 7 months (x2=0.531,P=0.466).The median titers of anti-HBs at 7 months were 10.44 mIU/mL in grouP of CD4+ T-lymphocytes ＜ 200/μL and 222.73 mIU/ml in group of CD4+ T-lymphocytes ≥200/μL.There was significant difference of anti-HBs titers between two groups (Z=-3.600,P＜0.01).No patients experienced side effects to HBV vaccine.Logistic regression model analysis indicated that only CD4+ Tlymphocytes was related to anti-HBs positivity after HBV vaccination.Conclusions HIV-1-infected patients with CD4+ T-lymphocytes ≥200/μL have higher serum anti-HBs positivity rates and higher anti HBs titers than patients with CD4+ T-lymphocytes ＜200/μL.However,patients with CD4+ T lymphocytes ＜200/μL also have relatively low immune response.Thus,HBV vaccination should be conducted in all these patients at high risk.

Objective To investigate the effects of hydrogen on post - cardiac arrest brain injury in rabbits.Method Sixty New Zealand rabbits were randomly divided into two groups,namely experiment group ( group A,n =30 ) and control group ( group B,n =30 ).Inhalation of 2％ hydrogen gas was conferred to rabbits immediately at the end of cardiac arrest modeling for 72 hours in the group A. Air instead was given to rabbits in the group B.Blood samples were collected before cardiac arrest (CA),and 4,12,24 and 72 hours after restoration of spontaneous circulation (ROSC) in all rabbits for determining the levels of hydrogen,tumor necrosis factor - α ( TNF - α),neuron - specific enolase (NSE) and protein S100β.At the same time,rectal temperature,mean arterial pressure,heart rate and respiration rate were recorded,and the neurologic deficit scoring (NDS) was carried out.The rate of systemic inflammatory response syndrome ( SIRS ) and the rate of survival of rabbits were analyzed. Results There was no significant difference in level of TNF - α activation between group A and group B within12 h of cardiopulmonary resuscitation (CPR).In group A,TNF - α level and the rate of SIRS peaked at 24 hours after CPR,which were higher than those in group B,and then decreased gradually,and the rate of survival was higher than that in group B in 72 hours after ROSC,the NSE was lower than that in group B at 24 hours after ROSC.In group B,S100β level began to increase significantly 4 hours after CPR,which was higher than that in group A,the level of NDS in group B was higher than that in group A 72 hours after ROSC.Conclusions Inhalation of hydrogen gas lessened inflammation and alleviated the brain injury after CPR.

Objective To probe into the psychological resilience and its influencing factor among parents of children with cancer.Methods A total of 125 parents were investigated by self-designed general information questionnaire,Connor-Davidson psychological resilience scale (CD-RISC),Chinese version of Parents' Perception Uncertainty in Illness Scale (PPUS),Social Support Rating Scale (SSRS),self-rating depression scale (SDS) and self-rating anxiety scale (SAS).Results The total score of psychological resilience was (54.86±12.88) and the illness uncertainty score was (91.52±14.66).The social support score was moderate with a total score of (39.86±7.99).The anxiety and depression among parents got a total score of (40.08±7.19) and (44.61±7.38) respectively.Psychological resilience was negatively correlated with illness uncertainty and depression,and was positively correlated with the social support.The depression,illness uncertainty,residence,children's age,clinical diagnosis entered into the multiple linear regression equation of psychological resilience,predicting 30.1％ of total variation in psychological resilience.Conclusions Social support,illness uncertainty and depression are the important factors which affect psychological resilience among parents of children with cancer.Nurses should assess the social support that parents receive,the level of depression and the disease feeling of the parents,and provide targeted interventions to relieve it,help to establish effective coping style and improve their psychological state.
