OBJECTIVETo explore the protection of high intensity microwave radiation on hypothalamo-pituitary-adrenal axis (HPAA) activity and hippocampal CA1 structure in rats and the protectiveeffect of Qindan Granule (QG) on radiation injured rats.

METHODSTotally 48 Wistar rats were randomlydivided into 8 groups, i.e., the normal control group, post-radiation day 1, 7, and 10 groups, 7 and 10days prevention groups, day 7 and 10 treatment groups, 6 in each group. Rats in prevention groups wererespectively administered with QG liquid (1 mL/100 g, 4. 75 g crude drugs) for 7 days and 10 days bygastrogavage and then microwave radiation. Then preventive effect for radiation injury was statisticallycalculated with the normal control group and the post-radiation day 1 group. Rats in treatment groupswere firstly irradiated, and then administered with QG liquid (1 mL/100 g, 4.75 g crude drugs). Finally preventive effect for radiation injury was statistically calculated with the normal control group, post-radiation day 7 and 10 groups. Contents of corticotrophin releasing hormone (CRH), beta endorphin (beta-EP), adrenocorticotropic hormone (ACTH), and heat shock protein 70 (HSP70) were detected. Morphological changes and structure of hippocampal CA1 region were observed under light microscope.

RESULTSCompared with the normal control group, contents of CRH and beta-EP significantly decreased in each radiation group. Serum contents of ACTH and beta-EP significantly increased in post-radiation day 1 and 7 groups (P < 0.05). Compared with radiation groups, beta-EP content in serum and pituitary significantly increased, and serum ACTH content significantly decreased in prevention groups (P < 0.05). Pituitary contents of CRH and beta-EP significantly increased in prevention groups. Serum contents of ACTH, beta-EP, and HSP70 were significantly lower in day 7 treatment group than post-radiation day 7 group (P < 0.05). Morphological results showed that pyramidal neurons in the hippocampal CA1 region arranged in disorder, with swollen cells, shrunken and condensed nucleus, dark dyeing cytoplasm, unclear structure. Vessels in partial regions were dilated with static blood; tissues were swollen and sparse. In prevention and treatment groups pathological damage of hippocampal CA1 region was obviously attenuated; neurons were arranged more regularly; swollen, pycnotic, or deleted neuron number were decreased; vascular dilatation and congestion was lessened.

CONCLUSIONQG could affect HPAA function and activity of high intensity microwave radiated rats, showing certain preventive and therapeutic effects of microwave radiated rats by adjusting synthesis and release of partial bioactive peptides and hormones in HPAA, improving pathological injury in hippocampal CA1 region.

OBJECTIVESTo observe the effects of NS-398 on proliferation of hepatic stellate cells (HSCs) in vitro, and to investigate the possible molecule mechanism.

METHODSHSCs were incubated with different concentrations of NS-398. The effects of NS-398 on cell proliferation was detected by MTT colormetric assay. The cell cycle of HSCs was analyzed by Flow Cytometry (FCM), cyclooxygenase-2 (COX-2) and proliferating cell nuclear antigen (PCNA) proteins in HSCs were detected by immunocytochemistry.

RESULTSAdministration of 20-160 micromol/L NS-398 significantly inhibited HSCs proliferation in dose-dependent manner compared with the control group (P less than 0.01). After treated with NS-398 at concentrations of 90, 120, and 150 micromol/L for 48 h, the number of HSCs in G(2)/M phase increased and the number of HSCs in G(0)/G(1) phase decreased (P less than 0.05); Incubated with 120 micromol/L NS-398 for 48 h, percentage of masculine cell of PCNA was 28.91%+/-0.11%, which was significantly lower than that of the control group (85.99%+/-0.13%) (P less than 0.01). Percentage of masculine cell of COX-2 was 13.80%+/-0.43%, which was not significantly different from that of the control group (14.07%+/-0.59%) (P more than 0.05).

CONCLUSIONSNS-398 could inhibit the proliferation of HSC-T6 and arrest HSCs in G2/M phase. Down-regulation of PCNA protein may partially accounted for the proliferation inhibition effect on HSCs induced by NS-398.

OBJECTIVETo carry out genotype analysis of enterovirus type 71, detected from hand-foot-mouth disease patients in Shenzhen in 2004.

METHODSAll samples were tested by reverse transcription-polymerase chain reaction (RT-PCR) using EV71 specific primer. The VP1 and VP4 of EV71 were cloned and sequenced. A phylogenetic tree was constructed by comparing the sequences with genogroups A, B and C genotypes using TreeView and PHYLIP software (3.6b).

RESULTSThe VP1 nucleotide sequence of 4 strains isolated from Shenzhen shared 87.8% - 92.0% identity with genogroup C, while the homogeneity of the VP4 nucleotide sequence was between 85.9% - 87.4%. The homogeneity of the VP1 nucleotide sequence with genotypes A and B was between 81.9% - 84.2% and was 80.6% - 85.0% with VP4. Among the 4 strains, the homogeneity of the VP1 nucleotide sequence was between 94.1% - 99.8% and was 100% with VP4 which formed a small group and could denominate EV71 genetype C4.

CONCLUSIONSimilar results were obtained from phylogenetic analysis of EV71 based on VP1 and VP4 nucleotide sequence. The four EV71 strains causing epidemic in Shenzhen could be named as C4 subgroups.
