Objective To evaluate the effect of recombinant human erythropoietin (rHuEPO) on lung injury induced by hepatic ischemia-reperfusion (I/R) in rats.Methods Sixty healthy male SpragueDawley rats, aged 6-8 weeks, weighing 220-280 g, were randomly divided into 3 groups (n=20 each) using a random number table: sham operation group (group S) , hepatic I/R group (group I/R), and rHuEPO group (group E).I/R and E groups underwent I/R of 70 percent of the liver.The rHuEPO 4 000 U/kg was injected intraperitoneally at 24 h before I/R in group E, while the equal volume of normal saline was given in S and I/R groups.The rats were sacrificed at 3 h of reperfusion, and lungs were removed and cut into sections which were stained with haematoxylin and eosin and examined under light microscope.Wet to dry lung weight ratio (W/D ratio) was calculated.The expression of heme oxygenase-1 (HO-1) and inducible nitric oxide synthase (iNOS) in lung tissues was determined by immunohistochemistry.The content of malondialdehyde (MDA), and activities of superoxide dismutase (SOD) and myeloperoxidase (MPO) in lung tissues were detected.Results Compared with group S, the W/D ratio, MDA content, and MPO activity were significantly increased, the SOD activity was decreased, the expression of HO-1 and iNOS was up-regulated (P＜0.05) , and the pathological changes of lung tissues were obvious in E and I/R groups.Compared with group I/R, the W/D ratio, MDA content, and MPO activity were significantly decreased, the SOD activity was increased, the expression of HO-1 was up-regulated, the expression of iNOS was down-regulated (P＜0.05) , and the pathological changes of lung tissues were reduced in group E.Conclusion The rHuEPO can alleviate hepatic I/R-induced lung injury in rats, and the mechanism may be related to up-regulated expression of HO-1 and down-regulated expression of iNOS.

Objective To explore the anticancer mechanism of esophageal cancer vaccines and clinical effect.Methods Esophagus cancer cells (Eca109) were cultured and the soluble antigen were extracted from the cells.Esophagus cancer vaccine was constructed with the antigen and superantigen SEC.Lymphocytes were isolated from peripheral blood and then stimulated with the vaccine in vitro.Phenotypes of the cells were checked by FCM and killing activity was tested with cytotoxic assays.One hundred and six early esophageal cancer patients were selected after surgery,who were divided into the observation group of 53 cases with esophageal cancer vaccine therapy and 53 cases in the control group with conventional treatment.Then clinical effect was observated and 3 year follow-up survival rate was observed of the of two groups of patients.Results Proliferation of vaccine stimulated lymphocyte group was the strongest,and high peaked at 72 h (A =0.22),and raise CD8+ T cell populations of CTLs.The killing activity of lymphocyte group stimulated by the vaccine against target cells was significantly higher than that of lymphocyte group ((97.36±2.11) ％) vs.(79.27±5.57) ％,F =38.62,P＜0.01).Three years follow up shows that the survival rates of experiment group were 48.27％ (male) and 45.83％ (female) respectively,and control group were 21.43％ (male) and 24.00％ (female),and the difference was significant (x2 =5.06,6.28,P ＜ 0.05).Conclusion The tumor vaccine constructed with esophagus cancer antigen and superantigen SEC can induce PBMC to activate and proliferate into CD8+ CTL with specific cytotoxicity against the cells which the antigen comes from.The vaccine may raise the survival rate of the patients with Esophagus cancer.

Objective To investigate the clinical features, diagnosis and treatments of pelvic abscess with endometriosis. Methods A retrospective analysis was performed on 129 cases of pelvic abscess in Peking Union Medical College Hospital from January 2000 to January 2016. Among them, 34 women with endometriosis were divided into the study group and the others were in the control group. The clinical characteristics, therapeutic regimens and outcomes were compared. Results (1) General conditions:there were no statistic differences between the two groups in age, WBC, serum CA125, intrauterine device in use, pelvic inflammatory disease history;while incidence rates of dysmenorrhea (65%, 22/34) and infertility (21%, 7/34) in the study group were higher than those in the control group (all P<0.05). (2) Clinical manifestations:fever, abdominal pain and pelvic mass were the main symptoms in two groups. The incidence rates of septic shock were 12%(4/34) in the study group and 2%(2/95) in the control group (P<0.05). (3) Treatment:treatment with puncture all failed in the study group (7/7) and surgeries were required. In contrast, there was only 1/19 treatment failure with puncture in the control group. The puncture failure rates were statistically significant (P<0.05). Compared with the study group and the control group, there were significant differences (P<0.05) in the operation time of laparoscopic surgery [(76±41) versus (53±21) minutes] and of laparotomy [(168±58) versus (116±35) minutes], intra-operative blood loss of laparoscopic surgery [(216±296) versus (43±36) ml] and of laparotomy [(448 ± 431) versus (145 ± 24) ml]. Conclusions Pelvic abscess in women with endometriosis is more severe and refractory to antibiotics and puncture treatment. Active surgical intervention is required. Although surgical procedures are often difficult, prognosis is comparatively satisfied.

Objective To investigate the effects of 3％ and 7.5％ hypertonic saline (HS) on hemorrhagic shock patients in Emergency Department.Methods From December 2008 to February 2012,patients older than 15 years with severe trauma and systolic blood pressure (SBP) ≤70 mmHg or 70 to 90 mmHg with heart rate≥ 108 per minute were divided into three groups randomly (random number).Group A:patients treated with 3％ hypertonic saline (HS) 300 mL + lactated Ringer' s solutions (LRS).Group B:patients treated with 7.5％ HS 300 mL + LRS.Group C:patients treated with LRS.The mean arterial pressure (MAP),blood pressure (BP),heart rate (HR) were recorded before infusion and at 10,30,45,60 minutes successively after infusion.Incidence of complications and mortality rates were compared between groups.Results Atotal of 148 patients were enrolled in this study.Compared with LRS grouop,MAP was restored more promptly and maintained persistently in 3％ HS group and 7.5％ HS group,and the total volume of fluid infused was decreased to almost 50％ of LRS in the first 1 hour.No significant differences in MAP levels were observed between group A and B except 30 minutes after infusion.Single bolus of 7.5％ HS infusion resulted in increased of HR to mean 127 beats per minute at 10 minutesafter fluid resuscitation.Higher incidence of arrhythmia and transient hypotension occurred in 7.5％ HS group.There were no statistical differences of changes of electrolytic indices,mortality rates,incidences of ARDS and MODS among three groups.Conclusions Resuscitation with 3％ HS provide similar benefits and lower risk of complications compared with 7.5％ HS and LRS.This study demonstrates the practicability and safety of 3％ HS for fluid resuscitation of patients with hypovolemic shock.
