UNLABELLEDTo observe the efficacy of adefovir dipivoxil(ADV) in combination with Anluohuaxian capsule in the treatment of chronic hepatitis B (CHB) patients.

METHODS72 cases with CHB were randomly divided into two groups. 36 cases of treatment group were given ADV combined with Anluohuaxian capsule for 48 weeks. 36 cases of control group were given ADV. The levels of serum ALT, AST, Alb, TBil, HA, LN, CIV, HBV DNA and hepatic tissue were compared before and after being treated.

RESULTSAfter 48 weeks treatment,the liver function, serum fibrosis index and histology of treatment group and control group all have improved. After treatment, the two groups in the levels of ALT(t=0.746, P=0.342), AST (t=0.369, P=0.713), TBil (t=0.146, P=0.684), Alb(t=0.148, P=0.883), liver tissue inflammation mobility scoring (t=1.666, P=0.100) and HBV DNA negative rate (x2=0.141, P=0.708) were no evident difference.The level of HA, LN, CIV were significantly lower in treatment group(101.58+/-30.11, 147.89+/-41.72, 38.75+/-9.50) compared with control group(182.25+/-117.59, 181.50+/-56.96, 74.92+/-31.14) (P less than 0.05). After the treatment, the liver tissue fibrosis scoring was significantly lower in treatment group (10.61+/-2.37) compared with before the treatment (12.28+/-3.16) (P less than 0.05).There was no difference found between after the treatment (11.36+/-2.93) and before the treatment (12.17+/-3.01) in control group (P more than 0.05).

CONCLUSIONSThe results show that the treatment with ADV in combination with Anluohuaxian capsule can play promoting antifibrotic effect and significant improved liver histology of chronic hepatitis B patients.

OBJECTIVETo observe the therapeutic effect of TCM syndrome-typing based therapy (TCM-STBT) combined with cyclosporin on myelodysplastic syndrome (MDS) and investigate the correlation of efficacy with TCM syndrome type and MDS type.

METHODSFifty-eight MDS patients were classified into refractory anemia (RA) and RA with excess blast (RAEB) by FAB standard and randomly divided into the cyclosporin group (the treated group) and the alltransretinoic acid group (the control group), and both were subjected to STBT additionally. The therapeutic effect and changes of peripheral hemogram were observed and compared.

RESULTSThe total effective rate and the total remission rate was 73% and 33% in the treated group, higher than that in the control group (39% and 0) respectively. Hemoglobin level, white blood cell and blood platelet count increased significantly in the treated group after treatment (P < 0.05), while only hemoglobin level rose obviously in the control group (P < 0.05). The total effective rate and markedly effective rate in patients with qi-blood deficiency syndrome type were higher than those with other syndrome types.

CONCLUSIONTCM-STBT combined with cyclosporin has good efficacy in treating MDS and there is well correlation between the therapeutic efficacy and type of TCM syndrome or of MDS, indicating the STBT is necessory for TCM therapy.

OBJECTIVETo study the feasibility and rationale of using a generalized regression neural network model integrated with multiple disease indicators for diagnosing alcoholic liver disease (ALD).

METHODSALD indicators were identified by reviewing the clinical testing results of 40 ALD patients from the literature and 135 patients from the Second Xiangya Hospital of Central South University, who were also classified by physician experts upon clinical consultation. Seven indicators were selected as diagnosis indexes and applied to a general regression neural network diagnostic model. Thirty-four of the reported patients and 120 of the clinical patients were selected for use as training samples to establish the indicator recognition pattern for the model, and the remaining six and 15 patients from the two respective groups were selected for use as testing samples to determine the model's diagnostic ability.

RESULTSThe model provided a correct diagnosis of ALD sub-classification for 94.1% (32/34) of the reported patients and 100% (120/120) of the clinical patients in the training set. The correct diagnosis rates achieved with the training sets were 100% for both the reported patient group (6/6) and the clinical patient group (15/15), indicating that the results of the diagnostic model were in good agreement with the ALD classifications generated by the clinical expert consultations.

CONCLUSIONThe general regression neural network model based on multiple indicators of ALD is capable of providing accurate and comprehensive diagnosis of ALD and may be feasible for clinical applications.

OBJECTIVETo find out how GATA-1 and GATA-2 behave in the bone marrow of patients with Monge's disease.

METHODSThe levels of mRNA in mononuclear cells (MNC) and proteins of GATA-1 and GATA-2 in the bone marrow of patients with Monge's disease and controls were determined by RT-PCR and immune cytolysis chemical method.

RESULTS(1) All patients and controls expressed GATA-1 mRNA (Monge's disease 1.033 +/- 0.146, Control 0.458 +/- 0.076) and GATA-2 mRNA (Monge's disease 0.451 +/- 0.073, Control 0.185 +/- 0.074). All patients expressed both GATA-1 (positive cell counts 77.3 +/- 33.3, positive score 135.4 +/- 75.4) and GATA-2 ( positive cell counts 29.4 +/- 11.4, positive score 48.4 +/- 19.7). All the controls expressed GATA-1 (positive cell counts 18.1 +/- 11.3, positive score 24.2 +/- 13.4) while 12 of 20 controls expressed GATA-2 ( positive cell counts 5.4 +/- 3.0, positive score 7.3 +/- 4.2). The expression of mRNA and proteins of GATA-1 and GATA-2 in Monge's disease were higher than in controls (P < 0.01). (2) There was a positive correlation between GATA-1 and Hb (P < 0.01), as did between mRNA and proteins of GATA-1 and GATA-2. (3) Both the proteins of GATA-1 and GATA-2 located only in the cytoplasm but not the nucleus.

CONCLUSIONSTwo of inherent genes, GATA-1 and GATA-2 which were expressed at higher levels in patients with Monge's disease than in controls might play significant roles in the pathogenesis of Monge's disease.

OBJECTIVETo investigate the effect of phenylephrine (an α-adrenergic agonist) on alveolar fluid clearance (AFC) in ventilator-induced lung injury and the possible mechanism involved.

METHODSA total of 170 male Wistar rats were randomly allocated into 17 groups (n=10) using random number tables. Short-term (40 minutes) mechanical ventilation with high tidal volume (HVT) was performed to induce lung injury, impair active Na+ transport and lung liquid clearance in the rats. Unventilated rats served as controls. To demonstrate the effect of phenylephrine on AFC, phenylephrine at different concentrations (1×10(-5), 1×10(-6), 1×10(-7), 1×10(-8), and 1×10(-9) mol/L) was injected into the alveolar space of the HVT ventilated rats. To identify the influence of adrenergic antagonists, Na(+) channel, and microtubular system on the effect of phenylephrine, phenylephrine at 1×10(-5) mol/L combined with prazosin (an α1-adrenergic antagonist, 1×10(-4) mol/L), yohimbine (an α2-adrenergic antagonist, 1×10(-4) mol/L), atenolol (a β1- adrenergic antagonist, 1×10(-5) mol/L), ICI-118551 (an β2-adrenergic antagonist, 1×10(-5) mol/L), amiloride (a Na+ channel blocker, 5×10(-4) mol/L), ouabain (a Na(+)/K(+)-ATPase blocker, 5×10(-4) mol/L), colchicine (a microtubular disrupting agent, 0.25 mg/100 g body weight), or β-lumicolchicine (an isomer of colchicine, 0.25 mg/100 g body weight) were perfused into the alveolar space of the rats ventilated with HVT for 40 minutes. AFC and total lung water content were measured.

RESULTSBasal AFC in control rats was (17.47±2.56)%/hour, which decreased to (9.64± 1.32)%/hour in HVT ventilated rats (P=0.003). The perfusion of phenylephrine at 1×10(-8), 1×10(-7), 1×10(-6), and 1×10(-5) mol/L significantly increased the AFC in HVT ventilated rats (all P<0.05). This effect of phenylephrine on AFC was suppressed by prazosin, atenolol, and ICI-118551 in HVT ventilated rats by 53%, 31%, and 37%, respectively (all P<0.05). The AFC-stimulating effect of phenylephrine was lowered by 33% and 42% with amiloride and ouabain, respectively (both P<0.05). Colchicine significantly inhibited the effect of phenylephrine (P=0.031).

CONCLUSIONPhenylephrine could increase the AFC in HVT-ventilated rats and accelerate the absorption of pulmonary edema.

BACKGROUNDRecent research suggests that beta(2)-adrenergic agonists increase alveolar fluid clearance (AFC) under physiologic and pathologic conditions. It is unknown whether beta(3)-adrenergic agonists also increase AFC under pathologic conditions. The aim of this study was to investigate the effect of beta(3)-adrenergic agonists on AFC following hypoxic lung injury and the mechanisms involved.

METHODSHypoxic rats were exposed to 10% oxygen. BRL-37344 (beta(3)-adrenergic agonist) or CGP-12177 (selective beta(3)-adrenergic agonist) alone or combined with beta receptor antagonists, sodium channel blockers, or Na(+)/K(+)-ATPase blockers were perfused into the alveolar space of rats exposed to 10% oxygen for 48 hours. Total lung water content (TLW) and AFC were measured.

RESULTSAFC did not change for the first 24 hours but then decreased after 48-hour exposure to 10% oxygen. The perfusion of BRL-37344 or CGP-12177 significantly increased AFC in normal and hypoxic rats. The AFC-stimulating effect of CGP-12177 was lowered with amiloride (a Na(+) channel blocker) and ouabain (a Na(+)/K(+)-ATPase inhibitor) by 37% and 49%, respectively. Colchicine significantly inhibited the effect of CGP-12177.

CONCLUSIONSThese findings suggest that beta(3)-adrenergic agonists can increase AFC during hypoxic lung injury in rats and accelerate the amelioration of pulmonary edema.

OBJECTIVETo compare and assess the effectiveness of leukocyte-filtered platelet and standard platelet concentrates transfusion in preventing platelet transfusion refractoriness (PTR) and human leukocyte antigen (HLA)-alloimmunization.

METHODSRandomized controlled trials (RCTs) or quasi-RCTs comparing leukocyte-filtered platelet with standard platelet concentrates transfusion (up to December 31, 2009) were searched and identified from Medline, EMBASE, The Cochrane Library, and CBM. A meta-analysis was conducted with Cochrane Collaboration's RevMan 5. 0.

RESULTSThe search identified 558 citations in total, in which 7 articles in English were finally included in the meta-analysis. The analysis showed that compared with standard platelet concentrates transfusion, leukocyte-filtered platelet transfusion significantly decreased PTR [ RR = 0. 59, 95% CI (0. 42, 0. 82) , P = 0. 002 ] and HLA-alloimmunization [ RR = 0. 49,95% CI (0. 33, 0. 74) , P =0. 0006]. Subgroup analysis showed that HLA-alloimmunization was significantly reduced by leukocyte-filtered platelet transfusion among the patients with acute myelocytic leukemia [ RR =0.42, 95% CI (0.32, 0.56), P <0. 00001], while no significant difference was detected in patients with acute lymphoblastic leukemia because of the limited sample size [ RR = 0. 50, 95% CI (0. 10, 2.41) , P =0. 39].

CONCLUSIONSThe current evidence shows that leukocyte-filtered platelet transfusion can prevent PTR and HLA-alloimmunization more effectively than standard platelet transfusion. Well-designed large-scale RCTs are still needed to further confirm this finding.

OBJECTIVETo study the anatomy of the anterolateral thigh perforators flap and explore its clinical application in the reconstruction of head and neck defects.

METHODSFive adult fresh cadavers were prepared, and morphosis and blood supply of anterolateral thigh flap perforators were examined by microsurgery anatomy. During dissections, the following parameters were recorded: number and type of perforators vessels, diameter of perforators, pedicle length, diameter of the original vessels, route (infra fascia and supra fascia); its position were located by anatomical landmark.

RESULTSThere were an average of (4.4 +/- 1.8) anterolateral thigh perforators flaps (ALTP flap) in each specimen with 68.2% musculocutaneous perforator and 31.8% septocutaneous perforator. The mean pedicle length of the largest perforator was (10.86 +/- 1.18) cm (8.29-14.44) cm, and its location was constantly concentrated in the superolateral region of the midpoint of the line linking the anterosuperior iliac spine and superolateral border of the patella. The distance between surface location of the largest perforator and the midpoint was (3.25 +/- 0.69) cm. Original vessel was mostly descend branch of lateral circumflex femoral artery/vein with average diameter of (3.16 +/- 0.59) / (3.08 +/- 0.02) mm.

CONCLUSIONALTP flap has constant position, large caliber, and long pedicle and therefore is useful for operation and option in reconstruction of head neck defects.

This study is to explore the possible mechanisms of the antidepressant-like effect of agmatine. By using two traditional "behavior despair" model, tail suspension test and forced swimming test, we examined the effects of some monoamine receptor antagonists (including beta-adrenergic receptor antagonist propranolol, beta-adrenergic receptor antagonist/5-HT1A/1B receptor antagonist pindolol, alpha2-adrenergic receptor antagonists yohimbine and idazoxan and 5-HT3 receptor antagonist tropisetron) on the antidepressant-like action of agmatine in mice. Activity of adenylate cyclase (AC) in the synapse membrane from rat frontal cortex was determined by radioimmunoassay. Single dose of agmatine (5-40 mg x kg(-1), ig) dose-dependently decrease the immobility time in tail suspension test in mice, indicating an antidepressant-like effect. The effect of agmatine (40 mg x kg(-1), ig) was antagonized by co-administration of beta-adrenergic receptor antagonist/5-HT1A/1B receptor antagonist pindolol (20 mg x kg(-1), ip), alpha2-adrenergic receptor antagonists yohimbine (5-10 mg x kg(-1), ip) or idazoxan (4 mg x kg(-1), ip), but not beta-adrenergic receptor antagonist propranolol (5-20 mg x kg(-1), ip) and 5-HT3 receptor antagonist tropisetron (5-40 mg x kg(-1), ip). Agmatine (5-40 mg x kg(-1), ig) also dose-dependently decrease the immobility time in forced swimming test in mice. The effect of agmatine (40 mg x kg(-1), ig) was also antagonized by pindolol (20 mg x kg(-1), ip), yohimbine (5-10 mg x kg(-1), ip), or idazoxan (4 mg x kg(-1), ip). Incubation of agmatine (0.1-6.4 micromol x L(-1)) with the synaptic membrane extracted from rat frontal cortex activated the AC in a dose-dependent manner in vitro. While the effect of agmatine (6.4 micromol x L(-1)) was dose-dependently antagonized by pindolol (1 micromol x L(-1)) or yohimbine (0.25-1 micromol x L(-1)). Chronic treatment with agmatine (10 mg x kg(-1), ig, bid, 2 w) or fluoxetine (10 mg x kg(-1), ig, bid, 2 w) increased the basic activity, as well as the Gpp (NH)p (1-100 micromol x L(-1)) stimulated AC activity in rat prefrontal cortex. These results indicate that regulation on 5-HT1A/1B and alpha2 receptors, and activation AC in the frontal cortex is one of the important mechanisms involving in agmatine's antidepressant-like action.
