CONCLUSIONS:Compared with chemotherapy alone group,Shenqi fuzheng injection combined with chemo-therapy can effectively improve the quality of life,and it is worth of spending more money on Shenqi fuzheng injection from the perspective of the pharmacoeconomics.

BACKGROUND: Dopamine is closely associated with occurrence of epilepsy and transmission in central nerval system, and its various functions are determined by specific receptors.OBJECTIVE: To establish temporal epilepsy model so as to probe into the influences of SCH23390, the antagonist of dopamine D1 receptors and haloperidol, the antagonist of dopamine D2 receptors injected in substantia nigra on temporal epileptic seizure induced by kainic acid and on electroencephalic activityDESIGN: Randomized controlled verified experiment.SETTING: Neurology Medicine Institute of Zhujiang Hospital Affiliated to Southern Medical University.MATERIALS: The experiment was performed in General Military Neurology Medicine Institute of Zhujiang Hospital Affiliated to First Military University of Chinese PLA from August to December 2004, in which, 30SD adult male rats were employed, massed varied from 250 to 300 g.METHODS: ① 30 rats were randomized into physiological saline (control) group (6 rats), kainic acid (KA) group (6 rats) and experimental group (18 rats). The experimental group was divided into 3 subgroups, named the antagonist of dopamine D1 receptors, SCH23390 + kainic acid group (D1 +KA group), the antagonist of dopamine D2 receptors,haloperidol + kainic acid group (D2+KA group) and physiological saline + kainic acid group (PS + KA group), 6 rats in each. In the control, physi ological saline 2 μL was injected in the right cerebral ventricle unilaterally. In KA group, kainic acid 2 μL was injected in the right ventricle. In each of experimental group, SCH23390, the antagonist of dopamine D1 re ceptors, haloperidol, the antagonist of dopamine D2 receptors and physio logical saline 1 μL for each was injected in substantia nigra on the right side successively and simultaneously, kainic acid 2 μL was injected in the right ventricle. ② Observed items: alters of EEG on the 0.5th 1st, 2nd, 6th and 24th hours after medication in each experimental group (compared with EEG of non-epileptic behavior, appearance of sharp wave, spike wave,sharp (spike) slow comprehensive wave and multi-spike slow wave determines epileptic activity) and changes in animal behaviors (0 grade: normal; Ⅰ grade: wet dog-like trembling, paroxysmal facial spasm, like winking,beard moving, rhythmic chawing; Ⅱ grade: rhythmic nodding; Ⅲ grade:paroxysmal spasm of anterior limbs; Ⅳ grade: paroxysmal spasm of bilateral anterior limbs when standing; Ⅴ grade: falling down, loss of balance and convulsion of four limbs). Cerebral hippocampal neural cell apoptosis was observed and the rats were sacrificed on the 5' day of medication. Cerebral hippocampal section was prepared and determined after in situ end labeling staining.MAIN OUTCOME MEAUSRES: ① Changes in behavior in rats before and after epilepsy and electroencephalogram (EEG) alters. ② Results of cerebra hippocampal neural cell apoptosis.RESULTS: Thirty rats entered result analysis. ① Epilepsy seizure: In the control group, there was no epilepsy attacked. In KA group, all of rats ap pear seizure, which attacked 10 minutes after KA injected in brain ventricle, reached the peak in 1 hour and stopped in 3 to 6 hours. ② EEG record: In the control group, there was not epileptic activity manifestations,like sharp wave, spike wave, spike slow comprehensive wave, etc. In KA group, epileptic wave presented in 10 minutes after injection, the seizure developed to the peak in about 1 hour, the wave amplitude was decreased in 3 to 6 hours, presenting paroxysmal slow and spike slow waves and no epileptic wave appeared after 12 hours. ③ Neuronal apoptosis: In the control group, few neural cell apoptosis was visible in hippocampus after injection.In KA group, neural cell apoptosis was visible obviously in hippocampus in 5 days after injection (P =0.00). With SCH23390, the antagonist of dopamine D1 receptors, hippocampal cell apoptosis was not reduced remarkably (P ＞0.05) and with haloperidol, the antagonist of dopamine D2 receptors injected in substantia nigra, hippocampal cell apoptosis was aggravated (P =0.00).CONCLUSION: Injection of SCH23390, the antagonist of dopamine D1 receptors in substantia nigra cannot block kainic acid inducing epilepsy and epileptic electroencephalic activity is not weakened remarkably. Injection of haloperidol,the antagonist of dopamine D2 receptors enhances epileptic electroencephalic activity in kainic acid induced epilepsy and increases cell apoptosis remarkably in cerebral hippocampal CA3 area.It is to explain that it is dopamine D2 acceptor that is involved in regulation of temporal epilepsy in substantia nigra rather than D1 acceptor.

Cerebrovascular disease and infection are the main causes of death.

Objective To explore the role and mechanism of microRNA-15b in the regulation of epithelial-mesenchymal transition (EMT) of human peritoneal mesothelial cells (HPMCs).Methods PCR assay was used to determine the expression of microRNA-15b in the HMrSV5 induced by 138mmol/L high glucose for 24 h.MicmRNA-15b mimic or inhibitor was transfected into human peritoneal mesothelial cells (HMrSV5) to over-express or down-regulate microRNA-15b.The cells were then incubated with 138 mmol/L high glucose for 24 h,and the expressions of E-cadherin(E-Cad),Vimentin (VIM),Fibronectin(FN) and Smad7 were detected by real-time PCR and Western blotting respectively.Results microRNA-15b in the HMrSV5 ceils was over-expressed and down-regulated.Increased level of microRNA-15b was obtained in HMrSV5 cells treated with high glucose.In vitro,high glucose led to the up-regulation of vimentin as well as fibronectin and the down-regulation of E-cadherin in HMrSV5 cells (all P ＜ 0.05),which indicated EMT and fibrosis.Suppression of microRNA-15b by transfection with microRNA-15b inhibitor partially reversed the EMT and fibrosis changes (P ＜ 0.05),while over-expression of microRNA-15b by transfection with microRNA-15b mimic obviously enhanced the EMT and fibrosis changes (P ＜ 0.05).Conclusions MicroRNA-15b mediates high glucose induced EMT in human peritoneal mesothelial cells by the inhibition of Smad7 possibly.MicroRNA-15b maybe a new target for the prevention and treatment of peritoneal fibrosis during peritoneal dialysis (PD).

Objective To evaluate the effect of ilaprazole enteric tablets on intragastric pH in duodenal ulcer patients. Methods A randomized, double blind, positive controlled clinical trial was carried out. A total of forty-two patients with duodenal ulcer were randomized into low dose ilaprazole group (5 mg/d), medium dose ilaprazole group (10 mg/d), high dose ilaprazole group(20 mg/d) and omeprazole group(20 mg/d). An ambulatory 24 hour intragastric pH study was performed at the fifth treatment day. Fraction time pH above 3, 4 or 5, median values of 24 hour diurnal pH and 12 hour nocturnal pH, the percentage of patients with total time pH above 3, 4 or 5 at least for 18 hours were evaluated. Results There were no significant differences of fraction time pH above 3 or 4, median values of 24 hour diurnal pH and 12 hour nocturnal pH and the percentage of patients with total time pH above 3, 4 or 5 at least for 18 hours among all the groups with different doses of ilaprazole and the omeprazole group. The fraction time pH above 5 in medium and high dose ilaprazole groups were (87.96 ± 12. 29)% and (89.86±15. 18)% respectively, which was higher than that in low dose ilaprazole group [(67. 17± 30. 16)%] and omeprazole group[(76. 14 ± 16. 75)%], P <0. 05. Conclusion Ilaprazole has a strong effect on intragastric acid control with a dose dependent trend.

OBJECTIVETo produce anti-19-Nortestosterone (NT) monoclonal antibodies and identify their immunological characteristics.

METHODSHybridomas were prepared by fusing NS0 mouse myeloma cells with splenocytes isolated from immunized BALB/c mice. Noncompetitive and competitive indirect ELISA were employed to screen positive cell clones. A caprylic acid ammonium sulphate (CAAP) method was used to purify NT mAb, and the Batty saturation method was used to determine the affinity constant (Kaff).

RESULTSFive hybridoma cell lines, named NT-1, NT-2, NT-3, NT-4, and NT-5, were identified and their corresponding mAbs were of the IgG(1) isotype with a k light chain. The Kaffs of all mAbs were between 2.6 and 4.7 × 10(9) L/mol. The titers and IC(50) values of purified ascite fluids were in the range of (0.64-2.56) × 10(5) and (0.55-1.0) ng/mL, respectively. Of all the cross-reacting steroids, (-NT was the most reactive with the mAbs at 62% with NT-1 mAb and 64% with NT-2 mAb. Negligible cross-reactivity (<0.01%) with other steroids was observed.

CONCLUSIONThe establishment of these hybridomas allows the potential development of a rapid test kit, and may provide an alternative method for the detection of NT residues in food producing animals.

OBJECTIVETo establish a peptide nucleic acid clamping PCR assay for detecting hepatitis B virus (HBV) drug resistance mutation.

METHODSRtM204I (ATT) mutant, rtM204V (GTG) mutant and rtM204 (ATG) wild-type plasmids mixed at different ratios were detected for mutations by PNA clamping PCR assay and direct sequencing, and the sensitivity and specificity of the two methods were compared. Serum samples from 85 patients with chronic HBV infection were detected for drug resistance using the two methods.

RESULTSThe sensitivity of PNA-PCR assay was 0.001% in a 10(5)-fold excess of wild-type HBV DNA with a detection limit of 10(1) copies. The sensitivity of direct sequencing was 10% with a detection limit of 10(4) copies. Mutants were detected in 73 of the 85 serum samples (85.9%), including YIDD in 40 samples, YVDD in 23 samples, and YIDD+YVDD in 10 samples. The agreement of PNA-PCR assay with direct sequencing was only 40% (34/85, YIDD in 21 samples, YVDD in 11 samples, and YIDD+YVDD in 2 samples). Neither of the two methods yielded positive results for the negative control samples, suggesting their good specificity.

CONCLUSIONPNA-PCR assay appears to be a more sensitive and rapid assay for detection of HBV genotypic resistance.
