Objective To explore continuous renal replacement therapy(CRRT) machine for plasma exchange in critical disease in children.Methods Retrospective study of 8 patients(8 month to 14 years,mean 5.7 years) and 32 plasma exchange treatments,after(adowble) lumen catheter inserted into the subclayian venous,using the Baxter BM25 machine with commercially available plasma filters.Results Five patients(3 ABO-incompatibility in bone marrow transplantation,1 thrombotic thrombocytopaenic purpura TTP,1 sepsis) gained full recovery.One systemic lupus erythematosus(SLE) and 1 sepsis experienced moderate improvement while 1 case of acute disseminated encephalomyelitis failed PE treatment.The average total exchange volume was 80-100 mL/kg,achieved at a blood flow rate of 5-10 mL/(kg?min) and a turnover rate of 60-120 mL/(kg?h) over a 3-hours duration.Thirty-one PE treatments were finished smoothly,one of which experienced the serious complication involving plasma filter.Conclusion Plasma exchange therapy is a safe and effective procedure for severe autoimmune abnormalities and pathogen removal in children.

Objective To investigate the influence of Helicobacter pylori(Hp) infection on gastric mucin MUC5AC and MUC6 expression in children.Methods Sixty-six cases with gastric biopsy specimens were obtained from 66 children undergone gastroscopy from Jan.2005 to Jun.2006 for episodic or continuous abdominal pain,nausea,vomiting,abdominal distension,retching and dyspepsia,and so on.Among these children,39 cases were male and 27 cases were female,owning a average age(8.8?3.0)years.These specimens were divided into 2 groups followed by the presence of Hp,which was detected by rapid urease tests and Hp-PCR.Gastric mucin MUC5AC and MUC6 mRNA were also measured by reverse transcription PCR(RT-PCR),and Hematoxylin and Eosin staining were used for pathology observation.Comparisons between every groups were performed using t test and ?2 test,and statistical significance was defined as P

Objective To evaluate the effects of ulinastatin on acute lung injury during ortho- topic liver transplantation(OLT).Methods Twenty ASAⅢ-Ⅳpatients with end-stage liver disea- ses.undergoing OLT were randomly divided into two groups.Ulinastatin group received intravenous infusion of ulinastatin(3?10~4 IU in 100 normal saline)after skin incision and every 4 h thereafter(n =10).Control group received same amount of normal saline instead of ulinastatin(n=10).Blood sam- pies were taken before skin incision,120 min after skin incision,30 min after liver was removed,5 min and 60 min after reperfusion of the graft and at the end of operation for determination of plasma IL-6, IL-8,TNF-?,MDA concentrations and SOD activity.Respiratory index(RI)[P_(A-a)DO_2/PaO_2]was cal- culated before skin incision,30 min after liver was removed,5 min and 60 min after reperfusion of the graft and at the end of operation.After anesthesia was induced,cardiac output,mixed venous oxygen saturation and central venous temperature were continuously monitored during operation.ECG,CVP, SpO_2,P_(ET)CO_2,radial artery and MPAP were also continuously monitored during operation.P_(ET)CO_2 was maintained at 35-40 mm Hg during operation.Blood temperature was maintained above 35.5℃during operation.Results In group C plasma IL-6 and IL-8 concentrations were significantly increased from 120 min after skin incision to the end of operation as compared with the baseline values(P0.05).RI was significantly lower at 60 min after reperfusion of the graft and at the end of operation in group U than in group C(P

Objective To investigate the effects of ulinastatin on the expression of neutrophil CD_(11b) and CD_(18) during orthotopic liver transplantation(OLT).Methods Forty patients with liver diseases,ASAⅢorⅣ, undergoing OLT were randomly divided into two groups.Ulinastatin group(n=20)received intravenous infusion of ulinastatin 3?10~5 IU in 100 ml normal saline after skin incision and repeated every 4 hours thereafter.Control group received same amount of normal saline instead(n=20).Blood samples were taken immediately before skin incision,120 min after skin incision,30 min of anhepatic phase,60 min of neohepatic phase and at the end of operation for measurement of CD_(11b) and CD_(18) expression of neutrophil by flow cytometry.Results CD_(11b)/CD_(18) expression was increased significantly in control group 60 min of neohepatic phase and at the end of operation compared to the level before skin incision,but in ulinastatin group there was no significant change in CD_(11b)/CD_(18) expression during the whole procedures(P＞0.05).CD_(11b)/CD_(18)expression was significantly lower 60 min of neohepatic phase and at the end of operation in ulinastatin group than in control group(P＜0.01).Conclusion Ulinastatin can inhibit the increase in CD_(11b)/CD_(18)expression during OLT,and be helpful for reducing the inflammatory response.

Taking application of some isolation and purification technologies, such as solvent extraction, preliminary solvent isolation, column chromatographies over silica gel and Sephadex LH-20 gel and preparative HPLC, 10 compounds were obtained from Gynura nepalensis cultivated in the suburban area of Beijing. Their structures were identified by spectroscopic methods and comparison with literature as (3R) -3-hydroxy-β-ionone (1), (3S,5R, 6S, 7E) -5, 6-epoxy-3-hydroxy-7-megastigmen-9-one (2), (+) -boscialin (3), 3, 6-trans-3-hydroxy-α-ionone (4), 3, 6-cis-3-hydroxy-α-ionone (5), 3, 4-cis-3, 4-dihydroxy-β-ionone (6), ethyl caffeate (7), loliolide (8), 1H-indole-3-carbaldehyde (9), and 3-(hydroxyacetyl)indole (10), respectively. All compounds were isolated from the title plant for the first time, and with compounds 1, 2, 4-7, 9 and 10 being isolated from Gynura species for the first time. Structurally, the above compounds 1-6 belong to C13 nor-sesquiterpenoids, sharing the same carbon skeleton of megastigmane. According to this study, they are one of major kinds of chemical constituents of Gynura nepalensis and have important reference value for the investigation on phytotaxonomy of this species.

Objective To investigate the molecular characteristics of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) patients receiving antiretroviral therapy (ART) in Guizhou Province. Methods Using a convenience sampling strategy, 8 583 samples were collected in Guizhou and an investigation was conducted including face-to-face questionnaire interview and HIV testing. Results 1 511 cases failed in HIV suppression (viral load, VL>1 000 copies/ml). 1 410 cases (93.31%) were successfully genotyped with HIV pol gene, among which 51.42% were genotyped as CRF01_AE, 26.67% as CRF07_BC and 16.1% as CRF08_BC. Conclusion The subtype changes caused by HIV gene mutation should precede the changes of main transmission routes of HIV through the analysis in recent years. Timely monitoring the changes of HIV subtypes can be one of the main bases for the prevention and control of AIDS.

Objective The aim of this study is to evaluate the efficacy and safety of preoperative CT-guided hardening agent localization.Methods From December 2010 to January 2012,27 patients with 29 solitary pulmonary nodules who had undergone CT-guided hardening agent localization and video-assisted thoracoscopic surgery (VATS) were studied.Results All cases were underwent CT-guided hardening agent localization successfully,and no patient had serious complication that required any intervention.The diameter of nodules ranged from 3 to 21 mm as measured by CT[mean (11.27 ± 6.32) mm].The distance between the center of nodule and visceral pleural ranged from 4 to 38 mm[mean (14.45 ± 4.32) mm].Conversion from VATS to thoracotomies was not necessary during the diagnostic resection procedure nodules.29 solitary pulmonary nodules underwent thoracoscopic wedge resection,and no intra-or postoperative mortality or morbidity was recorded.Conclusion CT-guided hardening agent localization before video-assisted thoracoscopic solitary pulmonary nodule resection is a safe and effective procedure for accurate diagnosis and resection of indeterminate solitary pulmonary nodules.
