Objective To statistically analyze data of blood transfusion from General Hospital of Chengdu Military Command,Mianyang field blood station,Deyang field blood station and other military medical institutions from May 12 to June 30,2008 so as to provided certain references for reasonable blood supportability in wartime and disaster.Methods A statistical analysis was done on data of blood collection and supply including self-taken blood and assembled blood,total amount of blood supply as well as the transfusion information of inpatients injured by earthquake in our hospital.Results The amount of self-taken blood was 5 111 U,the amount of assembled blood 3 380 U and the total amount of blood supply 1 0405.5 U.But blood transfusion was 4 090.6 U in 132 patients admitted into General Hospital of Chengdu Military Command.In addition,the crest-time of transfusion appeared at 96 hours after earthquake.Moreover,patients with fractures received the highest rate of blood transfusion and crush syndrome patients received the most blood transfusion and the highest per capita transfusion.Conclusions Blood supportability in earthquake is different from that in wartime and other disasters in aspects of transfusion time,blood types and blood transfusion volume.It is important to analyze the characteristics of transfusion in patients injured by earthquake for national strategy of blood supportability in disasters and for blood supportability in the wartime.

Objective To explore the distribution of pathogens, bacterial drug resistance, clinical features and prognosis of bacterial meningitis (BM) in children.MethodsThe clinical data of children diagnosed with BM during January 2011 to July 2015 were retrospectively analyzed. Children were divided into good outcome group and poor outcome group by the outcome at discharge. The distribution of pathogens, bacterial drug resistance, clinical features, and prognosis were analyzed among different groups.ResultsThere were included 95 children diagnosed with BM,. among whom 69 (72.6%) children had Gram-positive bacterial infections with predominantStreptococcus pneumonia (43 cases, 45.3%) and 26 (27.4%) children had Gram-negative bacterial infections with predominantEscherichia coli (13 cases, 13.7%). More than 50%Streptococcus pneumonia andEscherichia coli were resisted to penicillin. The neurological complications in children with BM included subdural effusions, hydrocephalus, cerebral parenchyma injury, and hearing and visual impairment, et.al. Multivariate logistic regression analysis showed that consciousness, coma, and low level of glucose in cerebrospinal lfuid were the independent risk factors for adverse outcome at discharge.ConclusionStreptococcus pneumonia andEscherichia coli were the predominant pathogens in children with BM with high resistance rate to penicillin. BM children may have varying degrees of neurological sequelae. The unconsciousness and low level of glucose in cerebrospinal lfuid were associated with unfavorable outcomes at discharge.

Objective To analyze the expression of serum anti M phospholipase A2 receptor (PLA2R)antibody in idiopathic membranous nephropathy (IMN),and to investigate its value in the diagnosis and evaluation of idiopathic membranous ne-phropathy.Methods One hundred and eighteen patients with biopsy-proved glomerular diseases were involved in this study, including 97 cases with IMN,21 cases with IgA nephropathy (IgAN)and 19 healthy people.ELISA was used to detect ser-um anti-PLA2R antibodies.Correlations of anti-PLA2R antibody level with laboratory parameters,including serum albumin, 24-hour urine protein of IMN patients were evaluated.Results The median of anti PLA2R antibody in IMN group,IgAN group and healthy group was 45.2(3.6~705.9)RU/ml,5.9(2.3~10.6)RU/ml and 1.2(0.6~9.3)RU/ml.The levels of serum anti PLA2R antibody in IMN group were higher than those in IgA nephropathy group and healthy control group.The difference was statistically significant (t=-5.027,-3.077;P=0.05).Among 97 cases with IMN,76 cases showed posi-tive anti-PLA2R antibodies (positive rate 78.35%).There was none patient showed positive anti-PLA2R antibody respec-tively in IgAN and healthy people.Furthermore,anti-PLA2R antibody level was negatively correlated with serum albumin (r=-0.453,P=0.000)and positively correlated with CREA,TC,ESR,24 hour urine protein (r=0.233,0.234,0.363, 0.586;P=0.004,0.217,0.021,0.000)in IMN patients.Conclusion Serum anti PLA2R antibody may be used as a IMN specific marker for the diagnosis of IMN,and it has important reference value for evaluating the severity of IMN.

Objective To investigate platelet-derived growth factor ( PDGF ) protection on blood flow and mitochondrial function of hemorrhagic shock rats. Methods Ninety-six SD rats were randomly divided into six groups including shock group, lactated ringer's solution (LR) resuscitation group,PDGF treatment groups(1,3. 5,7,15μg/kg). Laster-Doppler and oxygen concentration determination method were applied to observe the protective effect of PDGF treatment on animal survival,blood flow and mitochondrial function in liver and kidney. Re-sults As compared with LR resuscitation group,PDGF treatment increased animal survival rate and also improved blood fiow of liver and kindy,mitochondrial respiration control ration(RCR),of which the group with 3. 5μg/kg had the best result. Conclusion This finding sug-gests that PDGF may be a potential agent to treat acute critical such as hemorrhagic shock.

Objective To analyze the significance of postoperative radiotherapy for lymph node positive patients after radical resection of esophageal carcinoma.Methods Two hundred and sixty patients with esophageal squamous cell cancer,aged ≤70,with the performance status score of0 -1,who had undergone radical resection were divided into 2 equal groups:surgery alone group (Group A ) and surgery plus radiotherapy group (Group B).Group A was classified into 3 sub-groups:Group A1 (n =42)without lymph node involvement,Group A2 (n =43 ) with 1 to 3 involved lymph nodes,and Group A3(n =45) with ≥4 involved lymph nodes.Group B was classified into 3 sub-groups:Group B1 (n =43 )without lymph node involvement,Group B2 (n =44) with 1 to 3 involved lymph nodes,and Group B3(n =43 ) with ≥4 involved lymph nodes.The patients were followed up till death.Results The 1-,3-,and 5-year overall survival rates of Group A were 71.5％,35.4％ and 20％,respectively,all significantly lower than those in Group B (76.2％,48.5％ and 36.2％,respectively,x2 =7.822,P ＜0.05).The 1-,3-,and 5-year survival rates of Groups A1 were 83.3％,52.3％,and 38.1％,respectively,all not significantly different from those of Group B1 (81.3％,58.1％,and 46.5％,respectively,x2 =0.283,P ＞ 0.05 ).The 1-,3-,and 5-year survival rates of Groups A2 were 69.8％,34.9％,and 18.6％,respectively,all significantly lower than those of Group B2 (77.3％,47.7％,and 40.9％,respectively,x2 =4.188,P ＜ 0.05).The 1-,3-,and 5-year survival rates of Groups A3 were 62.2％,20％,and 4.4％,respectively,all significantly lower than those of Group B3 ( 69.8％,39.5％,and 20.9％,respectively,x2 =6.168,P ＜ 0.05).The 5-year metastatic lymph node rates of Groups A1 to A3 were 30.9％,53.4％,and 66.7％,respectively,all significantly higher than those of Groups B1 to B3 ( 11.6％,22.7％,and 30.2％,respectively,x2 =4.753,8.741,and 11.682,respectively,all P ＜0.05).The 5-year distant metastasis rates of Groups A1 to A3 were 11.9％,20.9％,and 31.1％,respectively,all not significantly different from those of Groups B1 to B3 (13.9％,20.4％,and 25.6％,respectively,x2 =0.079,0.003,and 0.203,respectively,all P ＞ 0.05 ).Conclusions Postoperative radiotherapy increases the survival rate of lymph node positive patients,but shows little efficacy on the lymph node negative patients.It reduces the occurrence of lymph node metastasis,even in the lymph node negative patients,and does not increase the morbidity of complications,especially that of anastomotic stenosis.The number of metastatic lymph node is one of the important factors affecting the survival of esophageal carcinoma.Distant metastasis increases along with the number of metastatic lymph nodes.

Objective To observe the efficacy and safety of recombinant human interleukin-11 (rnIL-11) in the treatment of thrombocytopenia induced by chemoradiotherapy in patients with solid tumor.Methods Solid tumor patients whose PLT count was lower than 50 × 109/L from December 2010 to December 2012 in PLA general hospital of Chengdu Commond were studied.They were divided into two groups randomly.The observed group was given subcutaneous injection of recombinant human interleukin-11 (Ⅰ) at the dose of 25 g · kg-1 · d-1,until the PLT rising subsolute value was more than 50 × 109/L.The control group was given usual treatment.The vital signs,hepatorenal function,coagulation function and cardio-pulmonary function of the patients were recorded during the whole process of treatment.Results The patients after chemotherapy had the platelet lowest average of (27.4 ± 7.6) × 109/L,and the average of the control group was (28.1 ± 7.9) × 109/L.The difference was not statistically significant (t =1.083,P ＞ 0.05),but treatment after the observation of elevated had the platelet highest average of (116.3 ± 22.8) × 109/L,which was significantly higher than that of (76.2 ± 21.3) × 109/L; the difference was significant (t =21.092,P ＜ 0.05).Platelets of patients in the observation group were ＜50 × 109/L for several days with an average of (4.3 ± 1.7) d,while platelets rose from the lowest value of the average absolute value greater than 50 000 hours (6.8 ± 2.4) d,shorter than the control group.By comparing the two groups,the differences were significant (t =11.347,P ＜ 0.05 ; t =15.196,P ＜ 0.05).Two groups of patients can tolerate adverse reactions.Ⅲ,Ⅳ degree of adverse reaction was not observed.Conclusion This study shows that rhIL-11 is well tolerated and has thrombopoietic activity in the treatment of thrombocytopenia.

Objective To explore the effects and the molecular mechanism of synergistic hepatocarcinogenesis of HBV and AFB1 in the development of HCC by studying the difference in protein expression profiles in hepatocellular carcinoma exposed to hepatitis B virus and Aflatoxin B1.Method 32 HCC specimens were labeled under four categories based on their biomarkers of HBV and AFB1 exposure:group A:HBV(+)/AFB1 (+),10 cases,group B:HBV(+)/AFB1 (-),10 cases,group C:HBV(-)/AFB1(+),6 cases,groupD:HBV(-)/AFB1(-),6 cases.Normal hepatic tissues from 10 cases of hepatic hemangioma,liver resection and liver transplant donor were chosen as the normal control group.Isobaric Tagging Reagent Quantitative (iTRAQ) Proteomics together with 2DLC MS/MS were applied to analyze the differentially expressed proteins among the 4 groups.Result (1) A total of 117 unique differentially expressed proteins including 53 up-regulated proteins and 64 down-regulated proteins were identified in the four groups.The number of unique differentially expressed proteins,including up-regulated and down-regulated proteins,in group A,group B,group C and group D were 106,97,104 and 74 respectively.(2) Among the 117 differentially expressed proteins,9 proteins were heat shock proteins or chaperones,and they were up regulated in group A,B and C.Besides,15 proteins were detoxification and drug metabolism pathway related proteins,12 of them were down-regulated in group A,and more than half of them were also down-regulated in group B and C.(3) The Reverse Transcriptase PCR result showed the mean expression level of AKR1B10 mRNA in group A was significantly higher than group B,C and D (all P＜0.05,respectively).Group C also showed significantly a higher expression level of AKR1B10 mRNA than group D (P＜0.05).The Western-blot results showed the mean expression level of AKR1B10 protein in group A was significantly higher than group B and D (all P＜0.05,respectively).Conclusions The up-regulated expression of heat shock protein and the down-regulated expression of most protein enzymes related to detoxification and drug metabolism were the common molecular biological events of HCC associated with exposure to HBV and AFB1.This suggested the synergistic hepatocarcinogenesis effects of HBV and AFB1 may be related to dysregulation of protein enzymes related to detoxification and drug metabolism.The overexpression of AKR1B10 may be involved in the AFB1-related hepatocarcinogenesis process.

Objective To evaluate the diagnostic and therapeutic role in bladder pain syndrome/interstitial cystitis (BPS/IC) of random bladder biopsy and hydrodistention with cystoscopy under anesthesia.Methods A retrospective review of cases in our BPS/IC center was performed from 2005 to 2010. One hundred and nineteen patients were included who are diagnosed as the bladder pain syndrome/interstitial cystitis (BPS/IC).There were 32 male patients,aged 47 to 64 years,and 56 years on average; 87 female cases,aged 23 to 67 years,49 years on average.Patients with bladder pain symptoms underwent a thorough evaluation which include voiding diary,pelvic pain、urgency and frequency questionnaire,urine culture,cytology,acid fast bacilli and upper tract imaging.Cystoscopy and random bladder biopsy had been undertaken with general anesthesia.Before and after hydrodistention with cystoscopy,the patients daily frequency of urination,the maximum urine volume,pain scores,symptom scores,QOL score were observed to understand whether there are significant improvement. Results One hundred and nineteen BPS/IC cases underwent random bladder biopsy and hydrodistention with cystoscopy under anesthesia,and finally 102 cases were confirmed of IC; 17 cases were not IC. Eight patients who were previously diagnosed as BPS/IC were found bladder transitional cell carcinoma as the cause of bladder pain symptoms( including 4 cases carcinoma in situ,1 case Low grade non-invasive bladder cancer,3 cases High grade invasive bladder cancers),and 4 of whom had no hematuria. Mean time from the occurrence of BPS to diagnosis of transitional cell carcinoma was 10.8 months. Three patients previously diagnosed as BPS/IC were found tuberculous cystitis as the cause of symptoms,and one eosinophilic cystitis,three chemical cystitis,two radiation cystitis were also detected.Before hydrodistention with cystoscopy under anesthesia,the daily frequency of urination in 102 cases diagnosed for IC patients was 42.1 ±5.6; the maximum urine volume was 141.0 ± 8.3 ml; pain score 7.6 ± 3.0; O'Leary-Sant questionnaire symptom score was 27.7 ± 4.2; QOL score was 7.6 ± 2.4.After hydrodistention with cystoscopy under anesthesia,the daily frequency of urination in 102 IC patients was 23.3 ± 3.4,and the maximum urine volume was 352.0 ± 1.7 ml ; pain score was 3.3 ± 4.3 ; O'Leary-Sant questionnaire symptom score was 12.5 ± 7.3 ; QOL score was 3.2 ± 5.1. Before and after hydrodistention with cystoscope under anesthesia,all of the daily frequency of urination,the maximum urine volume,pain scores,symptom scores,QOL score in 102 IC patients were significant improved (P ＜ 0.05 ). Conclusions BPS/IC remains a diagnosis of exclusion.Random bladder biopsy and hydrodistention with cystoscopy under anesthesia play an important diagnostic and therapeutic role in BPS/IC.
