Based on the ecological and economic problems in Good Agriculture Practice (GAP) of Chinese material medica, we introduced the origin, concept, features and operative technology of eco-agriculture worldwide, emphasizing its modes on different biological levels of landscape, ecosystem, community, population, individual and gene in China. And on this basis, we analyzed the background and current situation of eco-agriculture of Chinese materia medica, and proposed its development ideas and key tasks, including: (1) Analysis and planning of the production pattern of Chinese material medica national wide. (2) Typical features extraction of regional agriculture of Chinese materia medica. (3) Investigation of the interaction and its mechanism between typical Chinese materia medica in each region and the micro-ecology of rhizosphere soil. (4) Study on technology of eco-agriculture of Chinese materia medica. (5) Extraction and solidification of eco-agriculture modes of Chinese materia medica. (6) Study on the theory of eco-agriculture of Chinese materia medica. Also we pointed out that GAP and eco-agriculture of Chinese material medica are both different and relative, but they are not contradictory with their own features. It is an irresistible trend to promote eco-agriculture in the GAP of Chinese material medica and coordinate ecological and economic development.

Objective To study the gas analysis of umbilical cord artery blood and radial artery blood on predicating the prognosis of asphyxia neonate?Methods From September 2014 to September 2015, 328 neonates were divided into groups by Apgar score:290 patients in the control group and 27 patients in the mild asphyxia group,11 patients in the severe asphyxia group?After birth,umbilical artery blood,radial artery blood gas analysis was perfomed, oxygenation index was calculated, Outcome of neonatal behavioral neurological assessment ( NBNA) in neonates with asphyxia was regular follow?uped,the relationship between pH value and umbilical artery blood gas analysis was analyzed?Results The pH, PO2, PCO2 and oxygenation index of umbilical cord blood and radial artery blood in the severe asphyxia group was(7?11±0?25,(73?93±23?35) mmHg,(51?36±16?37) mmHg,206?23±98?12),significant different than the mild group(7?24±0?05,(86?35 ±12?56) mmHg,(45?89± 9?21) mmHg,411?22±57?94) and the control group(7?28±0?08,(87?80±12?07) mmHg,(43?68± 6?45) mmHg,426?23±73?30)(P<0?05)?The pH,PO2,PCO2 and oxygenation index of umbilical cord blood and radial artery blood in the severe asphyxia group was(7?25±0?18,(74?66±24?09) mmHg,(51?42±17?83) mmHg,332?03±65?19),significant different than the mild group(7?31±0?09,(87?24 ±11?75) mmHg,(45?73±10?21) mmHg,405?67±82?65) and the control group(7?32±0?06,(87?99±11?81) mmHg,(42?84± 9?32) mmHg,439?89±60?76)(P<0?05)?The NBNA scores of the severe asphyxia group was (34?09±5?02) points,lower than the mild group(36?62±2?04)(F=21?65,P<0?05)?The NBNA scores showed significant relationship with umbilical cord blood pH in the severe asphyxia group( r=0?877,P<0?01)?Conclusion The pH,PO2 and oxygenation index of umbilical cord blood and radial artery blood was lower while PCO2 was markedly high in the severe asphyxia group than other groups?For neonates, there is a correlation between umbilical cord blood pH and NBNAs core, neonates borned with hypoxia and acidosis should monitor blood gas analysis and oxygenation index dynamically

In this study, we investigate the bioaccessibility of heavy metals (Cu, Pb, As, Cd and Hg) in wild Artemisia annua and use target hazard quotients (THQ) proposed by US Environmental Protection Agency to assess the health risk under the heavy metal exposure. The results showed that the bioaccessibility of Cu, Pb, As, Cd and Hg in A. annua are 0.77, 0.66, 0.46, 0.68 and 0, respectively, and that the value of THQ for adults and children were 0.030 and 0.025 calculated by risk assessment model. The results indicated that the heavy metals in A. annua were not able to be completely absorbed by human body and that their contents were in a safe range. In this study, by combining the bioavailability of heavy metal and health risk assessment, we assessed the security of heavy metals of wild A. annua, which will provide reference for the standard of heavy metals for medicinal materials.

OBJECTIVETo investigate the current cognition of occupational exposure to human immunodeficiency virus (HIV) and the personal occupational protection awareness in healthcare workers in Liuzhou, China.

METHODSA total of 270 healthcare workers were selected from 10 hospitals in Liuzhou by stratified random sampling for a cross-sectional study. And a self-administered questionnaire of occupational exposure to HIV was designed to conduct a survey. The descriptive analysis of data was carried out by Excel. And a logistic regression analysis was done to analyze the effects of different factors on healthcare workers' cognition of occupational exposure to HIV using the statistical analysis software SPSS 19.0.

RESULTSA total of 260 usable questionnaires (96.3%) were returned. Among them, 220 healthcare workers (84.6%) had received the trainings on occupational exposure to HIV; 223 healthcare wofkers (85.8%) were aware of the rules and regulations on prevention of occupational exposure to HIV and the operation procedures in their hospitals. The healthcare workers who had not received the trainings or had not known the rules and regulations and the operation procedures were mainly from primary or secondary hospitals. A total of 106 healthcare workers (40.8%) had directly contacted patients' blood or body fluids; 154 healthcare workers (59.2%) were injured by sharp instruments, and most were hollow needle stick injuries (98/154, 63.6%). A total of 168 healthcare workers (68.08%) had better cognitive awareness of occupational exposure to HIV, and 76 healthcare workers (29.2%) had moderate cognitive awareness. Some healthcare workers had poor knowledge in the common sense of AIDS/HIV and occupational exposure to HIV, the personal protection awareness of occupational exposure, or the disposal measures after occupational exposure. The univariate analysis using chi-square test showed that occupation and professional title were significantly correlated with the cognition (P<0.05). The multivariate logistic regression analysis showed that the doctors (OR3.8; P<0.05), nurses (OR3.04, P<0.05), and laboratory technicians (OR=9.51, P<0.05) had better awareness compared with the others. The healthcare workers with a primary or lower professional title had poorer awareness compared with the healthcare workers with a higher professional title (OR=0.47, P<0.05).

CONCLUSIONHealthcare workers have the risk of occupational exposure to HIT. They do not have comprehensive and systematic knowledge related to occupational exposure to HIV, and they have a high demand for training.

Objective To observe the effect of acupuncture on ghrelin,estradiol (E2) and bone mineral density (BMD) in postmenopausal osteoporosis rats.Methods According to the random number table method,60 female Sprague-Dawley rats aged 3 months,were randomly divided into surgery group (40 rats) and sham group (20 rats).The osteoporosis model was established by bilateral ovariectomy.Three months after the operation,a significant decrease in BMD of lumbar vertebrae and femur of the model rats as measured by dual energy X-ray absorptionmetry against the sham group indicated successful establishment of the osteoporosis model.Then surgery group was randomly divided into a model subgroup,a acupuncture subgroup and an estrogen subgroup,with 10 rats in each subgroup.The acupuncture subgroup was treated with electroacupuncture,estrogen subgroup with subcutaneous injection of estradiol benzoate,sham group and model subgroup without any treatment.After 3 months of intervention all the rats were sacrificed,BMD of the lumbar vertebrae and femur was measured,ghrelin and E2 were determined.Results Serum ghrelin in acupuncture subgroup (399 pg/ml) and estrogen subgroup (276 pg/ml) were significantly lower (P ＜ 0.01) than that in model subgroup (546 pg/ml); serum E2 in acupuncture subgroup (128.02 pg/ml) and estrogen subgroup (182.89 pg/ml) increased significantly (P ＜ 0.05) than that in model subgroup (72.10 pg/ml) ;lumbar vertebrae BMD in acupuncture subgroup (0.212 g/cm2) and estrogen subgroup (0.231 g/cm2) increased significantly (P ＜ 0.05) than that in model subgroup (0.191 g/cm2),but in acupuncture subgroup the effect on improving the level of E2,ghrelin and lumbar vertebrae BMD was less than that in estrogen subgroup (P ＜ 0.05).Conclusions Acupuncture intervention can improve lumbar vertebrae BMD and serum E2 level of postmenopausal osteoporosis rat model,down regulate serum ghrelin level,but the overall effect of acupuncture is less than estrogen.

Objective To observe the effect of electroacupuncture (EA) on intestinal vitamin D receptor (VDR) mRNA and protein expression in ovariectomized rat model,and to explore the possible mechanism of acupuncture treatment for postmenopausal osteoporosis.Methods Sixty 3-month-old female SD rats were randomly divided into operation group and sham group.3 months after osteoporosis model was successfully produced,rats in operation group were randomly divided into model group,EA sham group,EA group and drug group.12 weeks after intervention,bone mineral density (BMD) of lumbar spine and femur were detected,then rats were all sacrificed to extract the small intestinal mucosa.VDR mRNA and protein expressions were determined by real-time quantitative PCR and Western blotting.Results The model of postmenopausal osteoporosis was successfully established.The bone mineral density was significantly improved in EA group and drug group as compared with the model group at 12 weeks after intervention.Western blotting and realtime quantitative PCR showed that small intestinal VDR mRNA and protein expressions were increased in EA group and drug group,but the increment of VDR mRNA expression was less in EA group than in drug group.Conclusions One of the mechanisms of acupuncture treatment for postmenopausal osteoporosis may be related with increasing the intestinal VDR mRNA and protein expression levels and enhancing the bioactivity of vitamin D.

Neurogenesis is a process in which the neuronal stem cells differentiate into functional neurons including the cell proliferation,differentiation and migration.Previously,it was believed that neurogenesis is a prenatal process and the adult ependymal cells are incapable of regeneration.Now it is clear that mammalian brain retains the ability to generate new ceils in specific regions.One of the regions is subventricular zone of the lateral ventricles,new generated neurons and glial cells later migrate to olfactory and repair dysosmia through the RMS road.Here we will review the advances in adult neurogenesis in mammal subventficular zone.
