Objective To evaluate urinary nucleosides determination for the diagnosis of colorectal carcinoma. Methods The concentrations of 14 different urinary nucleosides from 42 colorectal carcinoma patients, 10 patients with villous adenoma and 62 normal adults were determined by high-performance liquid chromatography (HPLC); Principal component analysis was applied to classify colorectal cancer patients and normal adults. Results The levels of Pseu、 C、 m1A、 mU、 m22G、 I、 m1G、 ac4C、 m6A in colorectal carcinoma group were (42.67?21.89)、(0.44?0.51)、(2.72?0.83)、(0.13?0.08)、(1.79?0.55)、(0.50?0.36)、(1.44?0.52)、(0.82?0.30)、(0.07?0.08)nmol/(?mol creatinine) respectively, which were much higher than those in normal adults (P

Objective To evaluate the effect of lappaconitine on renal ischemia-reperfusion (I/R) injury in mice.Methods Thirty-six male Wistar rats,weighing 180-220 g,were randomly divided into 3 groups (n=12 each) using a random number table:sham operation group (group S),group I/R and lappaconitine group (group LA).Renal I/R was induced by occlusion of the left renal pedicle for 45 min with atraumatic microclips followed by reperfusion,and the right kidney was removed after atraumatic microclips were released.At 30 min before reperfusion,lappaconitine 4 mg/kg was injected intraperitoneally in group LA,and normal saline 2 ml was given in S and I/R groups.In group S,the left renal pedicle was only isolated.At 5 and 24 h of reperfusion,blood samples were taken from the inferior vena cava for determination of serum creatinine (Cr) and blood urea nitrogen (BUN) concentrations,and kidney specimens were obtained for histopathologic examination (with light microscope) and for determination of the expression of cyclooxygenase-2 (COX-2) and matrix metalloproteinase-2 (MMP-2) in renal tissues (by immunohistochemistry).Results Compared with group S,the serum Cr and BUN concentrations were significantly increased,and the expression of COX-2 and MMP-2 in renal tissues was up-regulated at 5 and 24 h of reperfusion in I/R and LA groups.Compared with group I/R,the serum Cr and BUN concentrations were significantly decreased,the expression of COX-2 and MMP-2 in renal tissues was down-regulated at 5 and 24 h of reperfusion and histopathologic changes were reduced in group LA.Conclusion Lappaconitine can attenuate renal I/R injury through inhibiting the expression of COX-2 and MMP-2 in rats.

Objective To evaluate the efficacy and safety of de novo combination of tenofovir (TDF) plus lamivudine (LAM) based highly active antiretroviral therapy (HAART) for HBV-HIV coinfected patients.Methods Sixty patients with HBV-HIV co-infections admitted to Wuxi Fifth People's Hospital and Shanghai Public Health Clinical Center during January 2009 and December 2012 were enrolled.The patients were randomly divided into TDF + LAM based HAART group (TDF + LAM group,n =30) and LAM based HAART group (LAM group,n =30).All patients were treated for 72 weeks.SPSS 17.0 was used to compare the ALT normalization rate,HBV DNA negative conversion rate,serological response,HIV RNA negative conversion rate and CD4 + lymphocyte counts elevation rate between two groups at 24-,24-,48-and 72-week.Drug resistance and adverse reaction were observed.Results ALT normalization rates in TDF + LAM group at 24-,48-and 72-week were 83.3％,90.0％ and 93.3％,respectively,which were higher than those in LAM group (x2 =5.079,4.812 and 5.455,P ＜0.05).After 48 weeks of treatment,there were 28 patients (93.3％) in TDF + LAM group with the elevation of CD4 + lymphocyte counts ≥ 150 cells/μL,the rate was higher than that in LAM group (21/30,70.0％) (x2 =5.455,P ＜ 0.05).HBV DNA negative conversion rates in TDF + LAM group at 12-,24-,48-and 72-week were 60.0％,90.0％,93.3％ and 96.7％,respectively,which were higher than those in LAM group (x2 =4.800,5.963,5.455 and 9.017,P ＜0.05).No drug resistance and severe adverse reaction was observed in TDF + LAM group.Conclusion TDF + LAM based HAART is better in HBV viral suppression and liver function normalization,and has lower HBV resistance and higher CD4 + T lymphoeyte counts elevation rate than LAM based HAART for HBV-HIV co-infected patients.

Objective To evaluate the safety and tolerance of the first-line hiighly active antiretroviral therapy(HAART)regimen in Chinese HIV/AIDS patients.Methods The clinical data and laboratory results were retrospectively reviewed in 95 HIV/AIDS outpatients receiving first-line HAART regimen of zidovudine,lamivudine and efavirenz(or nevirapine)in Public Heahh Clinical Center Affiliated to Fudan University during January 2005 and August 2008.Mixed effects model and X2 test or Fisher test were used to analyze panel data and ratio data respectively.Results Totally 81%(77/95)patients had adverse events in the course of treatment,11.6%(11/95)developed grade 3 or higher adverse effects.Hematological adverse events and hepatotoxity were the most common in term of laboratory events with the total incidence of 46.3%(44/95)and 27.4%(26/95)respectively;8.4%(8/95)and 6.3%(6/95)were grade 3 or higher.In clinical events,30.5%(29/95),37.8%(36/95)and 27.4%(26/95)patients had dermatological,gastrointestinal and neurological adverse events respectively,however,only 1.1%(1/95)experienced grade 3 or higher dermatological adverse events.Conclusion The first line HAART regimen is safe and well tolerated in Chinese HIV/AIDS patients.

Objective To determine the concentrations of amphotericin B in serum and cerebrospinal fluid from patients with AIDS-associated cryptococcal meningitis.Methods Ten patients with AIDS-associated cryptococcal meningitis were enrolled in the study.Blood samples were collected before drug administrated at the 7th.14th and 21 th day after maintenance dose achieved.Cerebrospinal fluid samples were collected from lumbar puncture or taken before intrathecal drug administration at least one week after maintenance dose achieved.The concentrations of amphoteriein B in blood and cerebrospinal fluid samples were determined using RP-HPLC.Results When maintenance doses varied from 25 to 40 mg/d,the blood steady-state trough concentration range of amphotericin B was 1.34-2.27 ms/L,and that of cerebrospinal fluid was 44.0-9 1.7μg/L.Conclusions The concentrations of amphotericin B in the cerebrospinal fluid would be lower than the desired concentration if amphotericin B administrated only through intravenous or integrated with irregular intrathecal administration.It suggests that higher dosage of intravenous injection and regular intrathecal administration should be applied to achieve the desired concentration.

Objective To prepare a kind of superparamagnetic iron oxide (SPIO) and doxorubicin loaded multifunctional polymer microbubbles (MPMBs),and to explore its potential application as an ultrasound(US)/magnetic resonance (MR) imaging contrast agent in vitro.Methods The MPMBs and normal polymer microbubbles (PMBs) were made by double emulsion and freeze-drying methods.The physical property,drug encapsulation efficiency and the drug-loading efficiency of MPMBs were determined,and the release property and US/MR imaging enhancement of MPMBs were observed.Results The MPMBs had a regular shape and narrow size distribution.The drug encapsulation efficiency was (60.20±2.69) ％,and the drug-loading efficiency was (6.02 ± 0.27) ％.The in vitro release experiment showed that ultrasound can promote the release of doxorubicin in MPMBs.US imaging in vitro showed that the enhancement of MPMBs was better than PMBs,and MR imaging in vitro conformed that MPMBs could well enhance MR imaging.Conclusions The MPMBs is a multifunctional contrast agent with the treatment function as well as US/MR dual-mode imaging enhancement effect.
