OBJECTIVETo understand the relationship between the HIV-1 viral sequence variation and host factors associated with HIV-1 disease progression.
METHODSEnv and gag fragments of HIV-1 were amplified with PCR, cloned and sequenced. Bioinformatics was employed to find the genetic variation, N-linked glycosylation, hypermutation etc. Host gene polymorphism was analysed by using restricted fragment length polymorphism (RFLP).
RESULTSSignificant difference was found in genetic divergence between Env PCR dominant and clonal sequences (0.1 and 0.06, respectively) in non-treated group, but no significant difference was found in the HAART treated group. V3 GPGQ accounted for the most part in both treated and nontreated groups, rare V3 loop such as GPGH, GQGR and GLGR was found in treated group, V3 substitutions of I/V (position 12) and Y/H (position 21) was associated with the relatively rapid progression (RRP). Glycosylation was significantly higher in RRP than in TP for Env region, GA substitution in RRP was also significantly higher than that in TP group. SDF1-3primeA and CCR2 V64I gene frequency was higher in TP than in RRP, but the difference was not significant.
CONCLUSIONDisease progression was associated with V3 AA change, glycosylation and GA substitution in env gene. SDF1-3primeA, CCR2 V64I and CX3CR1 V249I/M280T was not associated with disease progression significantly.

OBJECTIVETo study the correlation factors of acute paraquat intoxication prognosis.
METHODSThe early paraquat concentration in plasma and urine, leukocyte count, hepatic and renal function, amylase, electrolyte and the parameters of arterial blood gas were analyzed retrospectively in 111 patients with acute paraquat intoxication.
RESULTS43 cases (38.7%) of all the 111 patients survived and the other 68 cases (61.3%) died. The patient, whose paraquat concentration was not more than 8.0 µg/ml in plasma and 276.0 µg/ml in urine, could survive. But some patients could die, only if there was no paraquat found in plasma. The paraquat levels in plasma and urine were significantly lower in survivors [(0.82 ± 1.70), (28.12 ± 51.17) µg/ml] than in nonsurvivors [(9.32 ± 12.04), (384.53 ± 597.93) µg/ml, respectively] (P < 0.01). The levels of leukocyte count, serum creatinine, aspartate aminotransferase (AST), and amylase were significantly higher in nonsurvivors than in survivors (P < 0.05, P < 0.01). In addition, metabolic acidosis was easier to appear in nonsurvivors. The multiple logistic regression analysis indicated that the paraquat concentration in plasma and urine, leukocyte count, creatinine and base excess were all related to survival.
CONCLUSIONThe higher paraquat concentration in plasma and urine, leucocytosis, renal dysfunction and metabolic acidosis are all important factors for the prognosis of paraquat intoxication.

Atorvastatin is proven to ameliorate cardiac hypertrophy induced by chronic intermittent hypoxia (CIH).However,little is known about the mechanism by which atorvastatin modulates CIH-induced cardiac hypertrophy,and whether specific hypertrophyrelated microRNAs are involved in the modulation.MiR-31 plays key roles in the development of cardiac hypertrophy induced by ischemia/hypoxia.This study examined whether miR-31 was involved in the protective role of atorvastatin against CIH-induced myocardial hypertrophy.H9c2 cells were subjected to 8-h intermittent hypoxia per day in the presence or absence of atorvastatin for 5 days.The size of cardiomyocytes,and the expression of caspase 3 and miR-31 were determined by Western blotting and RT-PCR,respectively.MiR-31 mimic or Ro 31-8220,a specific inhibitor of protein kinase C epsilon (PKCε),was used to determine the role of miR-31 in the anti-hypertrophic effect of atorvastatin on cardiomyocytes.PKCε in the cardiomyocytes with miR-31 upregulation or downregulation was detected using RT-PCR and Western blotting.The results showed that CIH induced obvious enlargement of cardiomyocytes,which was paralleled with increased atrial natriuretic peptide (ANP),brain natriuretic peptide (BNP),and slow/beta cardiac myosin heavy-chain (MYH7) mRNA levels.All these changes were reversed by the treatment with atorvastatin.Meanwhile,miR-31 was increased by CIH in vitro.Of note,the atorvastatin pretreatment significantly increased the mRNA and protein expression of PKCε and decreased that of miR-31.Moreover,overexpression of miR-31 abolished the anti-hypertrophic effect of atorvastatin on cardiomyocytes.Upregulation and downregulation of miR-31 respectively decreased and increased the mRNA and protein expression of PKCε.These results suggest that atorvastatin provides the cardioprotective effects against CIH probably via up-regulating PKCε and down-regulating miR-31.

Objective To study the directional migration of bone rnarrow-derived stenl cells (BMSCs)towards the glioma and the distribution of tbe migrated BMSCs in the brain. Methods In vitro cultured BMSCs isolated from the bone marrow of male Wistar rats were identified using immunofluorescence technique. and their stem cell properties wcrc assessed by means of induced differentiation in vitro into adipocytes and osteoblasts.Wistar rat models bearing glioma were established by stereotactic injection of C6 glioma cells into the basal ganglia,and 7 days later.Brdu-labeled BMSCs werc injected stereotaetically into the contralateral hemisphere or the contralateral ventricle, or intravenously via the tail vein.The rats were sacrificed 14 days afterthe BMSC injection,and coronal paraffin sections(5 μm thick)of the brain tissue were prepared.HE staining was used to observe the extent of intracranial glioma growth,and the distribution of the BMSCs in the glioma tissue as well as in the brain tissue was identified With immunofluorescent staining. ResuIts The BMSCs implanted into either the contrahteral hemisphere or the contralateral ventricle were found to migrate towards the glioma mostly along the needle tract,and distinct green fluorescence emitted by the labeled BMSCs Was detected on the boundary between the glioma and the normal brain tissue.A few fluorescent BMSCs were also seen around the glioma tissue after intravenous injection of the cells. Conclusion BMSCs injected into the cerebral parenchyma,contralateral ventricle,or the tail vein are capable of directional migration into the glioma tissue,suggesting their potential as a new vehicle for delivering therapeutic genes into the glioma tissue.

OBJECTIVETo investigate influence of electroacupuncture at "Zusanli" (ST 36) on pharmacokinetics after oral administration of Paracetamol in rats and explore the effect and mechanism of acupuncture combined with medicinal drugs.
METHODSForty-eight SD rats, in half respectively male and female, were randomly divided into 6 groups: Paracetamol groups of low, moderate, and high doses (oral dose of Paracetamol 300, 600 or 1200 mg/kg, respectively), and electroacupuncture plus Paracetamol groups of low, moderate, and high doses (electroacupuncture at "Zusanli" (ST 36) acupoint for 20 min after oral dose of Paracetamol 300, 600 or 1 200 mg/kg, respectively). Serum specimens of rats in each group were obtained at different time points to determine the concentrations of Paracetamol by RP-HPLC after oral administration of Paracetamol at different dosage, and the pharmacokinetic parameters were calculated by software 3P87, so as to observe the influence of electroacupuncture on absorption and metabolism of Paracetamol.
RESULTSExcept in electroacupuncture plus Paracetamol groups of high doses group showing a non-linear dynamics model, the pharmacokinetics parameters of Paracetamol in the other fives groups were all fitted to first order grade absorption of two-compartment open model. Compared with the Paracetamol groups of low and moderate doses, the time to peak concentration (T(max)) was advanced (P < 0.01), the peak values of plasma concentration (C(max)) were significantly higher (P < 0.01), and the absorption half-life (T1/2ka) speeded up apparently (P < 0.01), but the elimination half-life (T1/2ke) remained basically unchanged (P > 0.05), and the area under the curve (AUC) increased significantly (P < 0.01), and plasma clearance (Cl(s)) was lower (P < 0.01) in the electroacupuncture plus Paracetamol groups of low and moderate doses. Compared with the Paracetamol group of high doses, the AUC also increased significantly (P < 0.01) and the mean residence time (MRT) postponed relatively (P < 0.05) in the electroacupuncture plus Paracetamol group of high doses.
CONCLUSIONIt indicates that clinical consideration must be given to the drug dosage and the possible influence of electroacupuncture on the metabolism of some drugs in order to avoid and reduce adverse reactions.

ObjectiveTo explore the effect of Qingfei Jiangmai decoction (QJD) on the content of mercapturic acids in urine in healthy people amid PM2.5 (particles 2.5 microns or less in size) pollution. MethodA total of 84 healthy students of 18-30 years old in Beijing were recruited and they were randomized into the test group (42 in total, with 1 dropout) and control group (42 in total, with 3 dropouts). During the pollution, the test group and the control group respectively took QJD granules and placebo for 7 days (1 bag/time, 2 times/day), and another 7-day intervention with the same drugs was performed at an interval of 4 weeks. The time-activity patterns were recorded during the intervention. On-line solid phase extraction-liquid chromatography/tandem mass spectrometry (SPE-LC-MS/MS) was performed to detect the content of PM2.5-related metabolites S-phenylmercapturic acid (SPMA), 3-hydroxypropylmercapturic acid (3-HPMA), 3-hydroxy-1-methylpropylmercapturic acid (HMPMA), N-acetyl-S-(2-nitrile ethyl)-L-cysteine (CEMA), and N-acetyl-S-(2-hydroxy ethyl)-L-cysteine (HEMA) in urine before and after intervention. Statistical analysis was followed. ResultThe content of CEMA, HEMA, 3-HPMA, and HMPMA in the test group was all higher after the intervention than before the intervention, with the significant difference in HEMA (P<0.05). After intervention, content of HEMA and SPMA was significantly higher in the test group than in the control group (P<0.05), and the difference in HEMA (Z=-3.614, P<0.01) and HMPMA (Z=-1.988, P<0.05) before and after invention in the test group was significantly larger than that in the control group. After the intervention, HEMA in the test group was significantly higher than that in the control group (F=7.597, P<0.01). ConclusionDuring PM2.5 pollution, QJD can increase the excretion of HEMA, a metabolite of ethylene oxide, in the urine of healthy people in Beijing, and enhance the detoxification process of toxic components in PM2.5, which is of great value in preventing and treating haze-related illnesses.

OBJECTIVETo demonstrate the effect of bromoxynil on membrane potential and respiratory control rate (RCR) in isolate mitochondria from mice liver tissue in vitro and the intervention of NAC.
METHODSThe mitochondrial was randomized to control group, bromoxynil-poisoned group and NAC-protected group. S3, S4 and RCR of the mitochondria in each sample was detected by the method of oxygen electrode. Each sample was stained by JC-1 and the changes of membrane potential of mitochondria were observed under fluorescence microscope.
RESULTSThe S3 [(0.031 +/- 0.008) nano atoms oxygen x mg(-1) x min(-1)], RCR (1.820 +/- 0.181) of bromoxynil-poisoned group and RCR (4.253 +/- 0.210) of NAC-protected group were significantly lower than those of control group (P<0.01); the S4 [(0.017 +/- 0.004) nano atoms oxygen x mg(-1) x min(-1)] of NAC-protected group was significantly higher than control group (P<0.01). The S3 [(0.046 +/- 0.005) nano atoms oxygen x mg(-1) x min(-1)] and RCR of NAC-protected group were significantly higher than group B (P<0.01), S4 [(0.011 +/- 0.001) nano atoms oxygen x mg(-1) x min(-1)] of NAC-protected group was significantly lower than bromoxynil-poisoned group (P< 0.01). Observation under fluorescence microscope: the red fluorescence of mitochondria was dim or disappeared in bromoxynil-poisoned group while brightened in NAC-protected group but still dimmer than control group.
CONCLUSIONIn vitro, the mitochondrial RCR and the mitochondrial membrane potential are decreased after the mitochondria is incubated with bromoxynil, and NAC could improve it.
