OBJECTIVETo observe early rehabilitation of two different acupuncture programs for hemiplegia due to stroke.

METHODSSeventy cases of early hemiplegia due to stroke were randomly divided into a treatment group and a control group. The treatment group were treated by acupuncture at acupoints of both the healthy and affected sides, twice each day, respectively, and the control group by acupuncture at the affected side, once daily. Their therapeutic effects were evaluated by the brief Fugl-Meyer movement scale and the modified Barthel indexes.

RESULTSThe patients with over grade IV for FMA accounted for 68.6% and the good rate for ADL was 74.3% in the treatment group, and 31.4% and 42.8% in the control group, respectively, the therapeutic effect of the treatment group being better than that of the control group (P<0.01 or P<0.05).

CONCLUSIONThe acupuncture program in which acupoints at both the healthy and affected sides are applied alternately is more beneficial to recovery of motor function and activity daily living (ADL) of the patient with hemiplegia due to stroke.

To explore the genetic characteristics of viral quasispecies in HIV-1 CRF07_BC infections among intravenous drug users (IDU), the gp120 fragments of HIV-1 env gene were amplified from plasma samples collected from 6 CRF07_BC infected persons using single genome amplification and sequencing (SGA/ SGS) method, and 11 to 28 sequences were obtained from these samples, respectively, A neighbor-joining phylogenetic tree was reconstructed to describe the genetic characteristics of viral quasispecies. The Simplot, segments' phylogenetic trees and diversity plots based on average pairwise distance (APD) were used to identify the recombination events between quasispecies. The SGA sequences derived from single specimen formed a large monophyletic cluster in the neighbor-joining phylogenetic tree and showed the complex topologic structures of viral quasispecies. Of the 6 CRF07_BC infected patients, only one possessed the high genetic homogeneity, whereas the other five individuals showed high heterogeneity, with two to four subclusters inside the monophyletic cluster for each specimen. In addition, the recombinant events were identified among viral quasispecies from 3 cases. The results show SGA technique and phylogenetic analyses are useful tool to investigate the intrahost CRF07_BC gp120 complex quasispecies variation and high genetic diversity.

Objective To investigate the effect of preconditioning with cannabinoid CB2 receptor agonist AM1241 on microglial activation and injury induced by lipopolysaccharide ( LPS) and interferon-γ (IFN-γ). Methods The microglial cells were chosen and assigned to control group,AM1241 treatment group, LPS/IFN-γ inducement group and AM1241+LPS/IFN-γ treatment group. Cells of control group were cultured in normal medium;cells of AM1241 treatment group were preconditioned with AM 1241 for 2 h, and then the medium was changed with normal medium;cells of LPS/IFN-γ inducement group were exposed to the medium containing 1 μg/mL LPS plus 50 U/mL IFN-γ for 24 h;cells of AM1241+LPS/IFN-γ treatment group were preconditioned with AM1241, then the medium were changed with normal medium for 2 h, and at last, cells of this group were exposed to 1 μg/mL LPS plus 50 U/mL IFN-γ for 24 h. Microglial metabolism was assessed by MTT assay;NO release was measured by Reagent Kit;microglial shapes were observed through microscope. Results CB2 receptor agonist preconditioning can up-regulate the microglial CB2 receptor expression markedly;cell metabolism of AM1241+LPS/IFN-γ treatment group (92.55 ±8.37%) was obviously higher than that of LPS/IFN-γ inducement group (75.04±3.01%, P<0.05);AM1241+LPS/IFN-γ treatment group (43.44±5.52 μmol/L) released significantly less NO than LPS/IFN-γ inducement group (90.87±4.28 (μmol/L, P<0.05). Cells of the LPS/IFN-γ inducement group were destroyed seriously with enlarged soma and thickened and shortened pseudopodium;cells of the AM1241+LPS/IFN-γ treatment group were destroyed slightly with slightly enlarged soma and thickened and shortened pseudopodium. Conclusion Preconditioning with cannabinoid CB2 receptor agonist AM1241 reduces microglial activation and injury induced by LPS plus IFN-γ.

OBJECTIVETo investigate the preventive and therapeutic effects of enalapril maleate (Enalaprilat) (E) on myocardial damage in early stage after burns.

METHODSA total of 60 SD rats were subjected to 30% TBSA III degree scald injury, and randomly divided into scald group (with conventional fluid transfusion after scald) and ENA group (with intraperitoneal injection of 1 mg/kg Enalaprilat after scald). Normal control consisted of 6 rats. Plasma levels of cTnI and CK-MB were determined in all the groups at 1, 3, 6, 12, 24 post-scald hours (PSH) by enzyme linked immunosorbent assay. The pathological changes in myocardium were observed at the same time-points.

RESULTS(1) The serum level of cTnI and CK-MB in scald group were significantly higher than that of normal controls at each time-point (P < 0.01). The serum level of cTnI and CK-MB in ENA group were (1.32 +/- 0.12 microg/L to 2.47 +/- 0.22 microg/L) and (438 +/- 68 U/L to 5569 +/- 322 U/L), respectively, which were obviously lower than those in B group (6.42 +/- 0.96 microg/L to 15.10 +/- 3.69 microg/L) and (2556 +/- 74 U/L to 8047 +/- 574 U/L, P < 0.05 or P < 0.01) at different time-points. (2) Compared with normal controls, cloudy swelling, stromal blood vessel dilatation and congestion inflammatory cell infiltration were observed in scald group, but these pathological changes were less marked in ENA group.

CONCLUSIONSevere myocardial damage in rat occurred early after burns. Enalaprilat injection can markedly alleviate myocardial damage.

This study was purposed to investigate the reversal effect of gambogic acid (GA) on multidrug resistance of K562/A02 cells and its mechanism. The IC(50) (half maximal inhibitory concentration) of adriamycin (ADM) was evaluated by MTT. Cell apoptosis was detected by flow cytometry. Morphological changes of K562/A02 cells were observed by fluorescent microscopy with DAPI staining. The expressions of Survivin and P-gp were determined by Western blot. The results showed that the IC(50) of ADM on K562 and K562/A02 cell proliferation were (1.42 ± 0.07) µg/ml and (28.42 ± 1.40) µg/ml respectively. GA ≤ 0.0625 µmol/L had no inhibitory effect on proliferation of K562 and K562/A02. 0.0625 µmol/L GA could enhance the sensitivity of K562/A02 cells to ADM (P < 0.05) and the reversal multiples was 1.53. The apoptotic rate was raised after treating with ADM combined with 0.0625 µmol/L GA for 48 h (P < 0.05). Morphological differences were typical and obvious between cells of control and treated groups under fluorescence microscopy using DAPI staining. After treating K562/A02 cells with ADM combined with 0.0625 µmol/L GA for 48 h, the expressions of Survivin and P-gp were down-regulated at protein levels. It is concluded that GA can enhance the sensitivity of K562/A02 cells to ADM, which may be related to increasing cell apoptosis and down-regulating expressions of Survivin and P-gp.
