To investigate the suitable site environment for Atractylodes lancea, field trials in different niches was carried out, and the seedling growth, biomass and volatile oil components in different microhabitas was studied. The study found that the survival rate, plant height, volatile oil content of those which growing under the bamboo were significantly higher than those exposed in the open field. The survival rate understory was (76 ± 15.1) %, plant height understory was (77 ± 14. 8) cm and the summation of the four kinds of volatile oil content understory reached up to 4.09%; The same evaluation values of these indicators of the four faces in the open field respectively: survival rate is 30%, plant height was (77 ± 14.8) cm and the summation of the four kinds of volatile oil content was 2.24%. But, the yield of the understory (41 ± 22.3) g was significantly lower than those four faces in the open field (104.5 g) on the contrary. For the four open field towards, the yield of the east facing, which organic matter and other nutritional conditions were better than others, was significantly higher than those in the other facings. A. lancea was found to be an anti-poor and shading-like or growing in east facing slope herb through the correlation analysis of light, temperature, soil and leaf nutrients with seedling growth, biomass and volatile oil components. It also reminds us that the understory herb with high survival rate, low incidence, low management costs, and high medicinal ingredients, although it's production is not so high, but it can be improved by increased organic fertilizer. So the ecological planting patterns which can intercropping herbs with the forest was proposed.

OBJECTIVETo investigate the clinical efficacy, adverse reaction and safety of Jieyu pill (JYP) in treating depression.
METHODSThe randomized controlled trial was conducted in 28 patients in the treated group and 29 patients in the control group treated with maprotiline (Map). The efficacy of treatment was evaluated before treatment and 14, 28 and 42 days after treatment, with Hamilton depression rating scale (HAMD), self-rating scale for depression (SDS), self-rating scale for anxiety (SAS) and clinical global impression (CGI), the adverse reaction was assessed by Asberg Rating Scale (ARS).
RESULTSJYP was effective in treating depression, the markedly effective rate being 78.8%, corresponded to that of Map (82.8%, P > 0.05). After treatment, the scores assessed by HAMD, SDS and SAS were all lower than those before treatment (P < 0.01) respectively, but comparison between the two groups showed insignificant difference (P > 0.05). However, scores of ARS were significantly lower in the treated group than that in the control group, and the efficacy index of JYP was significantly higher than that of Map (P < 0.01).
CONCLUSIONJYP in treating depression shows the efficacy corresponded to that of Map and with less adverse reaction.

Objective To understand the current situation of iodine deficiency diserders(IDD) in Longyan City and to evaluate the effect of prevention and control measures of IDD in order to provide evidence for formulating prevention and control tactics. Methods During the year of 2006 and 2007, the 30 primary schools were screened by population proportion survey(PPS) from the 7 counties of Longyan City. Forty children aged 8-10 years in each school were randomly selected as a group to examine thyroid, and 7 children in each group were selected to measure the urine iodine and the salt iodine at the same time. The goiter rote, the median urinary iodine, the consumption rate of qualified iodized salt, the iodine salt coverage rate, the rate of qualified iodized salt and the non-iodized rate were detected. Results The goiter rate of children aged 8-10 years old in Longyan City was 0.94%(79/8438). The median urinary iodine was 259.12 μg/L. The consumption rate of qualified iodized salt was 97.86% (1462/1494). The iodine salt coverage rate was 99.46%(1486/1494). The rate of qualified iodized salt was 98.38 (1462/1486), and the non-iodized rate was 0.54% (8/1494). Conclusions All indicators have reached the national standard of eliminating IDD in Longyan City.

AIMTo study the effects of ginkgolides (Gin) on the expression of hypoxia-inducible factor-1alpha (H1F-1alpha) in primary cultured cortical neurons treated with CoCl2 and the relationship with ERK signal pathway.
METHODSWe observed the effects of Gin (37.5 mg/L) on morphology and viability on primary cultured cortical neurons with treatment of CoCl2 (125 micromol/L). The expression of HIF-1alpha and p-ERK of neurons induced by CoCl2 pretreated with Gin were assessed by Western-blot. We analyzed the relationship between HIF-1alpha expression activated by Gin and ERK signal pathway with treatment of PD98059 (100 micromol/L), a selective inhibitor of ERK.
RESULTSIt was shown that Gin had protective effects on CoCl2 damaged neurons by raising the neuronal viability. Some basic expression of HIF-1alpha and p-ERK were observed in normal cultured cortical neurons. The expression of HIF-1alpha and p-ERK increased strikingly when treated with CoCl2 for 4 h. The levels of HIF-1alpha and p-ERK increased even more in the neurons pretreated with Gin for 24 h before CoCl2. The levels of HIF-1alpha and p-ERK were notably inhibited with pretreatment of PD98059, while Gin could prevent this inhibition.
CONCLUSIONGin has protective effects on neurons damaged by CoCl2 which might be related to the increase of the level of HIF-1alpha and the activation of ERK signal pathway.

OBJECTIVETo investigate the growth and development of brain derived neurophic factor(BDNF)-positive neurons in the frontal lobe of human fetus.
METHODSThe expression of the BDNF-positive neurons in the frontal lobe of human fetus in the 2(nd),3(rd),and 4(th) month of gestation were observed with the streptavidin-biotin-complex/immunoperoxidase(SABC)method.
RESULTSBy the second month of gestation,BDNF-positive neurons were seen in the subventricular layer of the frontal lobe of cerebellum.By the third month of gestation,BDNF-positive neurons in the central layer were in various shapes,with big nucleus,less cytoplasm,and small processes.By the fourth month of gestation,BDNF-positive neurons in the central layer grew larger in size,cytoplasm increased,the BDNF-positive expression was enhanced with deeper dyeing,and the nerve fibers and particles were distributed between neurons;also,the BDNF-positive neurons were seen in the marginal layer of the frontal lobe of cerebrum.
CONCLUSIONBDNF-positive neurons may participate in the early development of the frontal lobe of cerebrum of human fetus.

OBJECTIVESTo explore a sensitive and specific method for detection of bcl-2/IgH gene rearrangement in diffuse large B cell lymphoma (DLBCL), and verify the credibility of the established method.
METHODSbcl-2/IgH hemi-nested PCR primers were designed using the professional primer design software. Fifty-two samples of pathologically diagnosed DLBCL and 10 fresh tonsil tissues were amplified using hemi-nested touch down-PCR to detect bcl-2/IgH gene rearrangement. The PCR products were cloned and sequenced.
RESULTSbcl-2/IgH gene rearrangement was detected in 6 of 52 DLBCL samples and 2 of 10 fresh tonsil tissues using one-way method. By using the hemi-nested PCR for the second round amplification, 5 of DLBCL were positive, but all of the fresh tonsil tissues were negative. The positive PCR products were sequenced and analyzed on the Internet, 3 of 8 cases obtained by one-way method were false positive, 5 positive cases amplified using hemi-nested PCR were all bcl-2/IgH gene rearrangement. PCR products of 3 false positive cases were homologous to BAC331191 and LLNLR-245D11 in human chromosome 19 and RP11-498P10 in chromosome 1.
CONCLUSIONThere are false positive results using common primers for detecting bcl-2/IgH gene rearrangement. The mechanism may be that highly homologous sequences to human genome exist in commonly used primers. The specificity of the diagnosis could be improved by hemi-nested PCR using the combination of primers we designed and the traditional ones.
