Abstract
OBJECTIVE To investigate the effect of electroacupuncture(EA) stimulation on proliferation and diffe-rentiation of endogenous neural stem cells as well as Jagged1/Notch1 pathway in AD model mice, so as to explore its mechanism underlying amelioration of AD. METHODS A total of 40 6-week-old male APP/PS1 transgenic AD mice were randomly divided into EA group (n=20) and AD model group ( n=20), and other 20 normal C57BL/6J mice of the same age were used as the normal control group. The mice in the EA group received EA (10 Hz, 2 mA) at "Baihui"(GV20), "Fengfu"(GV16) and bilateral "Shenshu" (BL23) for 20 min, once daily, 6 days a week for 16 weeks. The mice's learning-memory ability was detected by Morris water maze tests. The Aβ senile plaques in the hippocampal CA1 region were detected by Congo red staining, the immunofluorescence double label of BrdU, neuronal nuclear antigen (NeuN) and astrocyte specific protein GFAP in dentate gyrus of hippocampus was performed for detecting the proliferation and differentiation of the endogenous neural stem cells. The expression levels of Nestin (neuron specific protein) and GFAP were detected by Western blot, and those of Jagged1 and Notch1 mRNAs and proteins in the hippocampus were detected by real-time fluorescence quantifative PCR and Western blot. RESULTS Compared with the normal control group, the escape latencies at 2nd, 3rd and 4th day, and Aβ senile plaques were significantly increased (P<0.05, P<0.01), whereas the platform crossing times and time spent in the target quadrant, the expression levels of Jagged1 mRNA and Nestin protein were remarkably down-regulated (P<0.05) in the model group. Following EA intervention, the escape latencies at the 3rd and 4th day, Aβ senile plaques, immunofluorescence density of BrdU/GFAP, and GFAP protein expression were pronouncedly decreased (P<0.05, P<0.01), while the platform crossing times, platform quadrant residence time, immunofluorescence density of BrdU/NeuN, expression levels of Jagged1 and Notch1 mRNAs and proteins and Nestin protein evidently increased (P<0.05, P<0.01), suggesting an enhancement of proliferation and diffe-rentiation of endogenous neural stem cells into neurons and a suppression of the proliferation and differentiation towards astrocytes in the hippocampus. CONCLUSION EA at GV20, GV16 and BL23 can improve the learning-memory ability, promote the proliferation and differentiation of endogenous neural stem cells towards neurons and inhibit the proliferation and differentiation of endogenous neural stem cells towards astrocytes in the hippocampus, which may be achieved by regulating Jagged1/Notch1 pathway.

Abstract
Radiation-induced brain injury is a serious complication after cranio-cerebral radiotherapy, which affects the patient's quality of life and survival. A large number of studies have shown that various mechanisms such as neuronal apoptosis, blood-brain barrier damage, and synaptic dysfunction may be related to radiation-induced brain injury. Acupuncture has an important role in clinical rehabilitation of various brain injuries. As a new type of acupuncture, electroacupuncture has the characteristics of strong control ability, uniform and long-lasting stimulation, and is widely used in clinic. This article reviews the effects and mechanisms of electroacupuncture on radiation-induced brain injury, in order to provide a theoretical basis and experimental support for reasonable clinical application.

Abstract
Psoriatic arthritis is a chronic systemic autoimmune disease, characterized by psoriasis skin lesions and inflammation of the spine and joint. It has complicated clinical manifestations and individual variations. Nearly half of the patients will have joints erosion in two years, which is crippling. The severity of the skin and joint disease frequently do not correlate with each other. Currently, the understanding of the disease is insufficient in China with the lack of standardized diagnosis and treatment. Therefore, researchers from the Chinese Rheumatology Association formulated this specification based on the diagnosis and management experience together with guidelines at home and abroad. The specification summarizes the present situation of domestic diagnosis and treatment, aiming to standardize the diagnosis process and treatment protocols of psoriatic arthritis. Furthermore, it can reduce misdiagnosis and missed diagnosis, as well as improve the prognosis.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal malignancies with high mortality and short survival time. Computed tomography (CT) plays an important role in the diagnosis, staging and treatment of pancreatic tumour. Pancreatic cancer generally shows a low enhancement pattern compared with normal pancreatic tissue.
AIM To analyse whether preoperative enhanced CT could be used to predict postoperative overall survival in patients with PDAC.
METHODS Sixty-seven patients with PDAC undergoing pancreatic resection were enrolled retrospectively. All patients underwent preoperative unenhanced and enhanced CT examination, the CT values of which were measured. The ratio of the preoperative CT value increase from the nonenhancement phase to the portal venous phase between pancreatic tumour and normal pancreatic tissue was calculated. The cut-off value of ratios was obtained by the receiver operating characteristic (ROC) curve of the tumour relative enhancement ratio (TRER), according to which patients were divided into low- and high-enhancement groups. Univariate and multivariate analyses were performed using Cox regression based on TRER grouping. Finally, the correlation between TRER and clinicopathological characteristics was analysed.
RESULTS The area under the curve of the ROC curve was 0.768 (P < 0.05), and the cut-off value of the ROC curve was calculated as 0.7. TRER ≤ 0.7 was defined as the low-enhancement group, and TRER > 0.7 was defined as the high-enhancement group. According to the TRER grouping, the Kaplan-Meier survival curve analysis results showed that the median survival (10.0 mo) with TRER ≤ 0.7 was significantly shorter than that (22.0 mo) with TRER > 0.7 (P < 0.05). In the univariate and multivariate analyses, the prognosis of patients with TRER ≤ 0.7 was significantly worse than that of patients with TRER > 0.7 (P < 0.05). Our results demonstrated that patients in the low TRER group were more likely to have higher American Joint Committee on Cancer stage, tumour stage and lymph node stage (all P < 0.05), and TRER was significantly negatively correlated with tumour size (P < 0.05).
CONCLUSION TRER ≤ 0.7 in patients with PDAC may represent a tumour with higher clinical stage and result in a shorter overall survival.

Abstract
OBJECTIVE To observe the effect of electroacupuncture (EA) on the proliferation of endogenous neural stem cells in the hippocampus of young mice with Alzheimer's disease (AD), so as to explore its mechanisms underlying improvement of AD. METHODS Forty 1.5-month-old APP/PS1 transgenic male mice were randomly divided into an EA group and a model group, 20 mice in each group, and other 20 C57BL/6J male mice of the same age were used as the normal control group. EA (intermittment wave 10 Hz, 2 mA) was applied to "Baihui" (GV 20), "Fengfu" (GV 16) and "Shenshu" (BL 23) for 20 min, once a day, 6 days a week for 16 weeks. H.E. staining was used to assess histopathological changes of neurons of the hippocampal dentate gyrus. Immunohistochemical stain was used to detect the expression of 5-bromodeoxyuridine (BrdU)-positive in the hippocampus, and immunofluorescence double-labeled technique was used to detect the number of proliferated positive neurons of hippocampal neural stem cells. The expression levels of brain derived neurotrophic factor (BDNF) and Nestin mRNA and protein were detected by using real-time PCR and Western blot, separately. RESULTS The immunoactivity of BrdU, and the expression levels of BDNF and Nestin mRNA and protein in the hippocampus in the model group were significantly lower than in the normal control group (P<0.01, P<0.05), and considerably higher in the EA group than in the model group (P<0.01, P<0.05). The number of BrdU/NeuN dual labeled neurons was slightly increased in the model group than in the normal control group (P>0.05), and evidently increased in the EA group relevant to the model group (P<0.05), suggesting a proliferation of hippocampal neural stem cells. After modeling, the neurons of hippocampal dentate gyrus were arranged loosely and irregularly and their structure was fuzzy, with an appearance of different degrees of nuclear pyknosis, whereas in the EA group, the neuronal contour was clear and the nuclear structure was relatively distinct. CONCLUSION EA can activate the proliferation of neural stem cells in the hippocampus in AD mice, which may contribute to its function in improving the neuronal structure by upregulating the expression of BDNF.

Abstract
The aim of the present study was to investigate the effects of different courses of electroacupuncture on synaptic structure and synaptic function-related proteins expression in the hippocampal CA1 region of radiation-induced brain injury mice. Sixty C57BL/6J male mice were randomly divided into control group, radiation-induced brain injury model group, 1-week electroacupuncture group (EA1), 2-week electroacupuncture group (EA2), 3-week electroacupuncture group (EA3), and electroacupuncture-control (EA-Ctrl) group. The mice in model group were exposed to X-ray irradiation (8 Gy, 10 min) to establish radiation-induced brain injury model. The mice in EA groups were acupunctured at electroacupuncture points (Baihui, Fengfu and bilateral Shenshu) for 1 week, 2 weeks and 3 weeks respectively after radiation. Immunohistochemistry was used to observe synaptic structure in hippocampal CA1 region. The expressions of brain-derived neurotrophic factor (BDNF), synapsin-1 and postsynaptic density 95 (PSD95) in the hippocampal CA1 region of each group were detected by RT-PCR and Western blotting. The results showed that the nuclear gap in model and EA-Ctrl groups was significantly decreased compared to control group, however nucleus to cytoplasm ratio was significantly increased. The synaptic cleft, postsynaptic density (PSD) thickness, the mitochondrial surface density, volume density and specific surface area were significantly reduced. Compared with model group, the nucleus to cytoplasm ratio of EA2 group was significantly decreased, the PSD thickness and mitochondrial volume density were significantly increased; the nuclear gap of EA3 group was significantly increased, nucleus to cytoplasm ratio was significantly decreased, synaptic cleft and PSD thickness were significantly increased, and the mitochondrial surface density and specific surface area were all increased significantly. In addition, compared with the control group, the gene and protein expressions of BDNF, synapsin-1 and PSD95 in the hippocampal CA1 region of the model group and EA-Ctrl group were significantly decreased. However, compared with the model group, the gene expression of synapsin-1 in EA groups was significantly up-regulated, the gene expression of BDNF in EA1 and EA2 groups was significantly up-regulated, and the gene expression of PSD95 in EA2 group was significantly up-regulated. Moreover, the protein expressions of BDNF, synapsin-1 and PSD95 of EA groups were significantly up-regulated compared with the model group. These results indicate that the synaptic structure and the expression of synaptic function-related proteins in hippocampal CA1 region were injured by radiation exposure, whereas electroacupuncture intervention can significantly improve the synaptic structure and function damage caused by radiation.

Abstract
Garlic (Allium sativum L.) and its constituents have been shown to modify rumen fermentation and improve growth performance. Garlic skin, a by-product of garlic processing, contains similar bioactive components as garlic bulb. This study aimed to investigate the effects of garlic skin supplementation on growth performance, ruminal microbes, and metabolites in ruminants. Twelve Hu lambs were randomly assigned to receive a basal diet (CON) or a basal diet supplemented with 80 g/kg DM of garlic skin (GAS). The experiment lasted for 10 weeks, with the first 2 weeks serving as the adaptation period. The results revealed that the average daily gain and volatile fatty acid concentration were higher (P < 0.05) in lambs fed GAS than those in the CON group. Garlic skin supplementation did not significantly (P > 0.10) affect the α-diversity indices, including the Chao1 index, the abundance-based coverage estimator value, and the Shannon and Simpson indices. At the genus level, garlic skin supplementation altered the ruminal bacterial composition by increasing (P < 0.05) the relative abundances of Prevotella, Bulleidia, Howardella, and Methanosphaera and decreasing (P < 0.05) the abundance of Fretibacterium. Concentrations of 139 metabolites significantly differed (P < 0.05) between the GAS and the CON groups. Among them, substrates for rumen microbial protein synthesis were enriched in the GAS group. The pathways of pyrimidine metabolism, purine metabolism, and vitamin B6 metabolism were influenced (P < 0.05) by garlic skin supplementation. Integrated correlation analysis also provided a link between the significantly altered rumen microbiota and metabolites. Thus, supplementation of garlic skin improved the growth performance of lambs by modifying rumen fermentation through shifts in the rumen microbiome and metabolome.

Abstract
OBJECTIVE To screen protein target in prevention and treatment with electroacupuncture (EA) for Alzheimer's disease (AD) and explore the potential mechanism of EA in prevention of AD. METHODS A total of 40 APP/PS1 transgenic young male mice, 1.5-month old, were randomized into an EA group and a model group, 20 mice in each one, and 20 C57BL/6J mice were chosen as the normal control group. After adaptive housing for 1 week, the mice in the EA group were stimulated with EA at "Baihui" (GV 20), "Fengfu" (GV 16) and "Shenshu" (BL 23), with intermittent wave, 10 Hz in frequency and 2 mA in electric intensity. EA was given once daily, 20 min each time. There was 1 day at interval after EA for 6 days each week. Totally, the intervention lasted for 16 weeks. On day 3 after the end of EA intervention, Morris water maze test was adopted to detect learning and memory abilities of mice in each group. After water maze test, the label-free method was used to measure the difference expressions in cerebral cortex and hippocampus. Using Western blot method, the expressions of guanylate binding protein beta 5 (GNB 5) and histone-H 3 in cerebral cortex and hippocampus were verified. Using immunohistochemical method, the expressions of amyloid beta protein (Aβ) in cerebral cortex and hippocampus were detected. RESULTS Compared with the normal control group, the escape latency (on day 2, 3 and 4) was prolonged, the frequency of crossing platform and the duration of platform stay were decreased in the mice of the model group (P<0.05). Compared with the model group, the escape latency (on day 3 and 4) was shortened, the frequency of crossing platform and the duration of platform stay were increased in the mice of the EA group (P<0.05). By the comparison among the three groups, the high mobility group nucleosome-binding domain-containing protein 5, band 3 anion transport protein, histone-H 3, epoxide hydrolase 4 (fragment), neurolysin (mitochondria), phosphoglycerate mutase 2, GNB5 and Aβ were the differential proteins with the larger fold-change difference in expression. Compared with the normal control group, the expression of histone-H 3 in cerebral cortex and hippocampus was reduced (P<0.001) and the expressions of GNB 5 and Aβ were increased (P<0.001, P<0.01) in the mice of the model group. Compared with the model group, the expression of histone-H 3 in cerebral cortex and hippocampus was increased (P<0.001) and the expressions of GNB 5 and Aβwere reduced (P<0.001, P<0.05) in the mice of the EA group. CONCLUSION The intervention with EA effectively prevents from the decline of learning and memory ability and the formation of Aβ senile plaques in cerebral cortex and hippocampus in young mouse models of AD after growing up. Besides, EA plays a regulatory function for protein expression differences induced by AD model.

Abstract
OBJECTIVE To investigate the effect of electroacupuncture (EA) at "Baihui"(GV20), "Fengfu"(GV16) and bilateral "Shenshu"(BL23) on learning-memory ability, apoptosis in the hippocampus and expression of Aβ, Caspase 3, Bax and Bcl-2 proteins in the hippocampus and cerebral cortex in immature mice with Alzheimer's disease (AD), so as to explore its mechanism underlying improvement of AD. METHODS Forty APP/PS1 transgenic male young mice were equally randomized into model and EA groups and 20 C57BL/6J male young mice were used as the normal control. EA (10 Hz, about 2 mA) was applied to GV20-BL23 and GV16-BL23 for 20 min, once daily, 6 days a week for 16 weeks. The Morris water maze swimming test was used to evaluate the animals' learning-memory ability. Congo red staining and immunohistochemical staining were used to detect senile plaques in the hippocampus (dentate gyrus) and cerebral cortex tissues. Terminal deoxynucleotidyl transferase-mediated dUTP Nick-end Labeling (TUNEL) was used to detect the cellular apoptosis of hippocampus. The expression levels of apoptosis related factors Caspase 3, Bax and Bcl-2 were detected by Western blot. RESULTS After modeling, the escape latency of place navigation test of Morris water maze swimming tasks was significantly increased (P<0.05), while the number of platform crossing and residence time in the platform quadrant of spatial exploration test were significantly decreased in the model group in contrast to the normal control group (P<0.05). The number of apoptotic cells in the hippocampus and expression levels of Aβ, Caspase 3 and Bax proteins in the hippocampus and cerebral cortex were significantly up-regulated in the model group relevant to the normal control group (P<0.05). Following EA intervention, the escape latency of place navigation test of Morris water maze swimming tasks was significantly decreased (P<0.05), while the number of platform crossing and residence time in the platform quadrant of spatial exploration test were significantly increased in the EA group in contrast to the model group (P<0.05). The hippocampal apoptotic cells, the expression of Aβ, Caspase 3 and Bax proteins in hippocampus and cerebral cortex were evidently down-regulated in the EA group in contrast to the model group (P<0.05). Whereas the ratio of Bcl-2/Bax was significantly decreased in the model group relevant to the normal control group (P<0.05) and considerably increased in the EA group in contrast to the model group (P<0.05). No significant changes were found in the expression levels of Bcl-2 after modeling and after EA intervention (P>0.05). CONCLUSION EA of GV20, GV16 and BL23 can effectively improve the learning-memory ability in AD mice, which may be related to its function in inhibiting neuronal apoptosis in the hippocampus and down-regulating the expression levels of Aβ, Caspase 3 and Bax proteins in both hippocampus and cerebral cortex.

Abstract
Calcitonin gene-related peptide (CGRP) is a neuropeptide coded by the calcitonin gene and divided into α and β subtypes. CGRP is widely distributed throughout the human body and highly expressed in the peripheral and central nervous system. Studies have shown that CGRP plays a role in a variety of physiological and pathophysiological activities, such as the formation and transmission of nociceptive signal, as well as the regulation of cardiovascular function. Recently, more and more researches have shown that CGRP is involved in the regulation of synaptic plasticity, cognitive function and learning memory in the central nervous system. This paper reviews the role of CGRP in regulation of synaptic plasticity and process of emotional memory, hoping to provide a new molecular target and theoretical basis for clinical treatment of neurological diseases.

Abstract
Diogenites are a group of meteorites that are derived from the interior of the largest protoplanet Vesta. They provide a unique opportunity to understanding together the internal structure and dynamic evolution of this protoplanet. Northwest Africa (NWA) 8321 was suggested to be an unbrecciated noritic diogenite meteorite, which is confirmed by our oxygen and chromium isotopic data. Here, we find that olivine in this sample has been partly replaced by orthopyroxene, troilite, and minor metal. The replacement texture of olivine is unambiguous evidence of sulfur-involved metasomatism in the interior of Vesta. The presence of such replacement texture suggests that in NWA 8321, the olivine should be of xenolith origin while the noritic diogenite was derived from partial melting of pre-existing rocks and had crystallized in the interior of Vesta. The post-Rheasilvia craters in the north-polar region on Vesta could be the potential source for NWA 8321.

Abstract
The purpose of this study was to explore the effects of calcitonin gene-related peptide (CGRP) on the long-term depression (LTD) of hippocampus in mice. Sixty C57BL/6J mice (30 days old) were randomly divided into control group, three CGRP (50, 100, and 200 nmol/L) groups, CGRP + CGRP8-37 group and CGRP + APV group (10 mice for each group). The effects of exogenous application of different concentrations of CGRP on synaptic plasticity and LTD in hippocampus of mice were detected by in vitro recording of local field potential. The results showed that higher doses (100 and 200 nmol/L) of CGRP significantly enhanced the induction of LTD in the hippocampus. Moreover, CGRP increased the magnitude of N-methyl-D-aspartate (NMDA) receptor-mediated excitatory postsynaptic currents. The above-mentioned effects of CGRP were blocked by either CGRP selective antagonist CGRP8-37 or NMDA receptor antagonist APV. These results suggest that CGRP can dose-dependently enhance the induction of LTD in hippocampus of mice, and the underlying mechanism involves the mediation of NMDA receptor function.

Abstract
OBJECTIVE To observe the influence of different courses of electroacupuncture (EA) intervention on recognition memory and the proliferation and differentiation of hippocampal neural stem cells in mice with radiation-induced brain injury, so as to explore its mechanisms underlying improving radiation-induced brain injury. METHODS Se-venty 30-day old C57BL/6J mice were randomly divided into control, model and EA groups, and the latter two groups were further divided into 1 week (W), 2 W and 3 W subgroups (n=10 in the control group and each subgroup). The ra-diation-induced brain injury model was established by radiating the mouse' left head at a dose of 8 Gy for 10 min by using a radiation linear accelerator. EA (1.5 V, 2 Hz/10 Hz) was applied to "Baihui" (GV20), "Fengfu" (GV14) and bilateral "Shenshu" (BL23) for 30 min, once daily for 1, 2 and 3 weeks, respectively. The learning-cognition memory ability was detected by using novel object recognition test in an open test box to record the time for exploring a novel object (TN) and a familiar object and to calculate the recognition index (RI). The neural stem cells' proliferation and differentiation in the hippocampus tissues were evaluated by counting the number of bromodeoxyuridine (BrdU)-labeled cells, neuronal nuclei (NeuN)/BrdU-positive cells and BrdU/glia fibrillary acidic protein (GFAP)-positive cells under microscope after immunofluorescence stain. RESULTS After modeling, the TN at 90 min and 24 h and RI of the model subgroup 3 W at 90 min and RI of the model subgroup 1, 2 and 3 W at 24 h were significantly decreased in comparison with those of the control group (P<0.01, P<0.05). Moreover, the number of BrdU-positive cells in the model subgroup 1 W and 2 W, the BrdU/NeuN double-labeled cells in the 3 model subgroups and BrdU/GFAP double-labeled cells in the model subgroup 1 W and 3 W were significantly decreased (P<0.01, P<0.05). Following EA interventions, the TN in the 3 EA subgroups at both 90 min and 24 h, and RI of EA subgroup 3 W at 90 min and EA subgroup 2 W and 3 W at 24 h were considerably increased compared with those of the corresponding 3 model subgroups (P<0.05, P<0.01). The numbers of BrdU-positive cells as well as BrdU/NeuN and BrdU/GFAP double-labeled cells were significantly increased in the 3 EA subgroups (P<0.05, P<0.01, P<0.001). CONCLUSION EA of GV20, GV14 and BL23 can improve the recognition memory ability of mice with radiation-induced brain injury, which may be related to its effect in promoting the proliferation and differentiation of stem cells in the hippocampus.

Abstract
Objective: To Effects of n-hexane on learning and memory and the expressions of nerve growth factor (NGF) mRNA and nerve growth factor receptor (NGFR) mRNA of brain tissue in mice exposed to N-hexane. Methods: 40 Kunming mice were randomly divided into low-dose group, meddle-dose group, high-dose dose group and control group, with 10 mice in each group. All the groups were orally exposed to n-hexane in different doses: low-dose group with 43.5 mg/kg, middle-dose group with 86.5 mg/kg and high-dose group with 173.0 mg/kg, 1 time per day for 20 d. After the poisoning, the Y-arm test and the expressions of NGF mRNA and NGFR mRNA and the concentrations of NGF and NGFR in the brain tissues of each group were measured. Results: In the first Y-arm test, there existed a significant difference in correct reaction rate generally in all groups (P<0.05), and correct reaction rate in the middle-dose group and the high-dose group were low significantly compared with that in the control group(P<0.05). In the second Y-arm test, there existed a significant differences in total electric shock time and correct reaction rate generally in all groups (P<0.01), and the total electric shock time prolonged significantly and the correct response rate decreased significantly in 3 dose groups compared with those of the control group(P<0.05). The expression levels of NGF mRNA in brain tissues of low, meddle and high dose-groups were 0.81±0.66, 0.67±0.37 and 0.69±0.26, and the expression levels of NGFR mRNA were 1.22±0.42, 1.98±0.84 and 2.01±2.01, respectively. Compared with the control group, the expressions of NGF mRNA in the 3 dose groups decreased significantly (P<0.05), and the expression of NGFR mRNA in middle-and high-dose groups increased significantly (P<0.05). The concentrations of NGF in brain tissues of low,meddle and high dose-groups were 39.97±7.24 ng/L, 39.26±7.88 ng/L,31.70±8.21 ng/L,and the concentrations of NGFR were 17.37±6.82 ng/L,21.37±7.16 ng/L, 22.46±7.70 ng/L, respectively. Compared with the control group, the concentrations of NGF in high-dose groups decreased significantly(P<0.05), and the concentrations of NGFR in middle-and high-dose groups increased significantly (P<0.05). Conclusion: N-hexane exposure can result in decrease of learning and memory in mice, which may be related to abnormal expression of NGF mRNA and NGFR mRNA in brain tissue.

Abstract
The present study was aimed to investigate the effects and mechanisms of electro-acupuncture (EA) on proliferation and differentiation of neural stem cells in the hippocampus of C57 mice exposed to different doses of X-ray radiation. Thirty-day-old C57BL/6J mice were randomly divided into control, irradiation, and EA groups. The control group was not treated with irradiation. The irradiation groups were exposed to different doses of X-ray (4, 8 or 16 Gy) for 10 min. The EA groups were electro-acupunctured at Baihui, Fengfu and bilateral Shenyu for 3 courses of treatment after X-ray radiation. Immunohistochemistry was used to evaluate proliferation and differentiation of the hippocampal neural stem cell. RT-PCR and Western blot were used to detect mRNA and protein expressions of Notch1 and Mash1 in the hippocampus, respectively. The results showed that, compared with the control group, the numbers of BrdU positive cells (4, 8 Gy subgroup) and BrdU/NeuN double-labeling positive cells (3 dose subgroups) were decreased significantly in the irradiation group, but the above changes could be reversed by EA. Compared with the control group, the number of BrdU/GFAP double-labeling positive cells in each dose subgroup of irradiation group was decreased significantly, while EA could reverse the change of 4 and 8 Gy dose subgroups. In addition, compared with the control group, the expression levels of Notch1 mRNA and protein in hippocampus were up-regulated, and the expression levels of Mash1 mRNA and protein were significantly decreased in each dose subgroup of irradiation group. Compared with irradiation group, the expression levels of Notch1 mRNA and protein in hippocampus of EA group were decreased significantly in each dose subgroup, and the expression levels of Mash1 mRNA and protein were increased significantly in 4 and 8 Gy subgroups. These results suggest that irradiation affects the proliferation and differentiation of neural stem cells in hippocampus of mice, whereas EA may significantly increase the proliferation and differentiation of hippocampal neural stem cells via the regulation of Notch signaling pathway.

Abstract
Traditional bulk polymerization imprinted technology and existing surface imprinted technology have some congenital defects. Therefore, it is necessary to design more efficient surface imprinted technology. In this paper, novel surface imprinting technology with higher imprinting efficiency is well designed. It fully realizes the synchronization of polymer crosslinking and template imprinting. Then the surface imprinted polymers (SIPs) are synthesized using metal ions as a template. The physicochemical characteristics of the SIPs are characterized by scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET) studies, Fourier transform infrared spectroscopy (FTIR) and elemental analysis. The adsorption performances and recognition selectivity of the SIPs towards the template are investigated by a batch method. The experimental results show that the SIPs possess excellent adsorption ability and selectivity towards the template. The selectivity coefficients of the SIPs prepared in this study are higher than those of IIPs prepared by other imprinting methods. The adsorption process could be well described by the Lagergren-first-order model and Langmuir monolayer chemical adsorption. The SIPs have good chemical stability and reusability. Consecutive adsorption–desorption experiments show that the exhausted SIPs could be effectively regenerated, and the regenerated SIPs could be reused without a significant reduction in adsorption capacity or selectivity coefficient. SIPs have good chemical stability and reusability. They could be reused without a significant reduction in adsorption capacity and selectivity coefficient.![]()

Abstract
The purpose of this study was to explore the effects of different concentrations of calcitonin gene-related peptide (CGRP) on long-term potentiation (LTP) in the hippocampus of mice. C57BL/6J mice (30 days old) were randomly divided into control group, three CGRP groups, and CGRP + CGRP8-37 group (10 mice for each group). Different concentrations of CGRP (50, 100 and 200 nmol/L) were given to the hippocampal slices of mice. The presynaptic release of neurotransmitters and the induction of LTP were measured by extracellular field recording techniques. The result showed that different concentrations of CGRP did not affect the presynaptic release of neurotransmitters, but 100 and 200 nmol/L CGRP increased the amplitude of LTP induced in the hippocampus of mice. This facilitation effect of CGRP was blocked by its specific antagonist CGRP8-37. These results suggest that CGRP dose-dependently facilitates the induction of LTP in the hippocampus of mice through its specific receptor.

Abstract
The aim of the present study was to explore the effects of different doses of calcitonin gene-related peptide (CGRP) injected into the central nucleus of amygdala on cognitive function, learning and memory of mice. C57BL/6J mice (30 days old) were randomly divided into control, sham, and three CGRP groups (10 mice for each group). Three doses of CGRP (200, 400 and 800 ng) were bilaterally administered into the central nucleus of the amygdala. Open field test was used to assess cognitive function. Novel object recognition and Morris water maze test were used to evaluate learning and memory of the mice. The results of open field test showed that 800 ng CGRP significantly increased the locomotive score. The results of novel objective recognition test showed that 400 ng CGRP significantly increased the recognition index. Compared with control group, 400 and 800 ng CGRP groups showed significantly shortened latency period and increased crossing times. Simultaneously, the latency periods of 400 and 800 ng CGRP groups were shorter than that of 200 ng CGRP group. These results suggest that bilateral injection of CGRP into amygdala dose-dependently enhances the learning and memory function of mice.

Abstract
STUDY HYPOTHESIS Is it possible to immunologically activate human cervical epithelial cells to produce antiviral factors that inhibit herpes simplex virus type 2 (HSV-2) replication? STUDY FINDING Our results indicate that human cervical epithelial cells possess a functional TLR3/RIG-I signaling system, the activation of which can mount an Interferon-λ (IFN-λ)-mediated anti-HSV-2 response. WHAT IS KNOWN ALREADY There is limited information about the role of cervical epithelial cells in genital innate immunity against HSV-2 infection. STUDY DESIGN, SAMPLES/MATERIALS, METHODS We examined the expression of toll-like receptors (TLRs) and retinoic acid-inducible I (RIG-I) in End1/E6E7 cells by real-time PCR. The IFN-λ induced by TLR3 and RIG-I activation of End1/E6E7 cells was also examined by real-time PCR and ELISA. HSV-2 infection of End1/E6E7 cells was evaluated by the real-time PCR detection of HSV-2 gD expression. The antibody to IL-10Rβ was used to determine whether IFN-λ contributes to TLR3/RIG-I mediated HSV-2 inhibition. Expression of interferon regulatory factor 3 (IRF3), IRF7, IFN-stimulated gene 56 (ISG56), 2'-5'-oligoadenylate synthetase I (OAS-1) and myxovirus resistance A (MxA) were determined by the real-time PCR and western blot. End1/E6E7 cells were transfected with shRNA to knockdown the IRF3, IRF7 or RIG-I expression. Student's t-test and post Newman-Keuls test were used to analyze stabilized differences in the immunological parameters above between TLR3/RIG-I-activated cells and control cells. MAIN RESULTS AND THE ROLE OF CHANCE Human cervical epithelial cells expressed functional TLR3 and RIG-I, which could be activated by poly I:C and 5'ppp double-strand RNAs (5'ppp dsRNA), resulting in the induction of endogenous interferon lambda (IFN-λ). The induced IFN-λ contributed to TLR3/RIG-I-mediated inhibition of HSV-2 replication in human cervical epithelial cells, as an antibody to IL-10Rβ, an IFN-λ receptor subunit, could compromise TLR3/RIG-I-mediated inhibition of HSV-2. Further studies showed that TLR3/RIG-I signaling in the cervical epithelial cells by dsRNA induced the expression of the IFN-stimulated genes (ISGs), ISG56, 2'-5'-oligoadenylate synthetase I (OAS-1) and myxovirus resistance A (MxA), the key antiviral elements in the IFN signaling pathway. In addition, we observed that the topical treatment of genital mucosa with poly I:C could protect mice from genital HSV-2 infection. LIMITATIONS, REASONS FOR CAUTION Future prospective studies with primary cells and suitable animal models are needed in order to confirm these outcomes. WIDER IMPLICATIONS OF THE FINDINGS The findings provide direct and compelling evidence that there is intracellular expression and regulation of IFN-λ in human cervical epithelial cells, which may have a key role in the innate genital protection against viral infections.

Abstract
C-repeat-binding factor (CBF)/dehydration-responsive element (DREB) transcription factors play key roles in plant stress responses. However, little information is available on the regulation of CBF/DREB expression. In this study, we isolated and characterized the FeDREB1 promoter sequence from the common buckwheat accession Xinong 9976. To identify the upstream region of the FeDREB1 gene required for promoter activity, we constructed a series of FeDREB1 promoter deletion derivatives. Each deletion construct was analyzed through Agrobacterium-mediated transient transformation in tobacco leaves treated with 4°C cold or drought stress. Promoter-beta-glucuronidase fusion assays revealed that the pCD1 (-270 bp) deletion in the upstream region of FeDREB1 could activate expression of the GUS gene at 4°C. The pCD1 (-270 bp), pCD2 (-530 bp), and pCD3 (-904 bp) deletion induced low-level GUS expression under drought stress. However, the pCD4 (-1278 bp) deletion clearly activated GUS gene expression. Our results suggest that sections pCD1 (-270 bp) and pCD4 (-1278 bp) in the FeDREB1 gene promoter are new sources of induced promoters for adversity-resistance breeding in plant genetic engineering.

Abstract
Chlorfenapyr is a promising pyrrole insecticide with a unique mechanism of action that does not confer cross-resistance to neurotoxic insecticides. The effect of chlorfenapyr on pyrethorid-resistant Culex pipiens pallens Coq (Diptera: Culicidae) has not been fully investigated under laboratory conditions. In this study, cypermethrin-resistant C. p. pallens exhibited 376.79-fold and 395.40-fold increase in resistance to cypermethrin compared with susceptible strains after exposure for 24 and 48h, respectively. Larvae and adults were tested for susceptibility using dipping, topical, and impregnated paper methods as recommended by the WHO. No cross-resistance to chlorfenapyr was found. Increased mortality was apparent between 48 and 72h, indicating a slow rate of toxic activity. Synergism experiments with piperonyl butoxide (PBO) showed an antagonistic effect on chlorfenapyr toxicity. Mixtures of chlorfenapyr and cypermethrin could therefore provide additional benefits over either insecticide used alone. Mixtures of 5ng/ml chlorfenapyr and 500ng/ml cypermethrin exhibited a slight synergistic effect on cypermethrin-resistant mosquitoes (3.33, 6.84 and 2.34% after 24, 48 and 72h exposure, respectively. This activity was lost when the chlorfenapyr concentration was increased to 10 or 20ng/ml. Chlorfenapyr showed quite good results for pyrethroid-resistant C. p. pallens, and could improve public health by reducing the occurrence of mosquito bites and subsequently protecting against transmission of lymphatic filariasis and Japanese encephalitis.

Abstract
Epidermal growth factor receptor (EGFR) is considered to be one of the key driver genes in non-small cell lung cancer (NSCLC). Several clinical trials have shown great promise of EGFR tyrosine kinase inhibitors (TKIs) in the first-line treatment of NSCLC. Many advances have been made in the understanding of EGFR signal transduction network and the interaction between EGFR and tumor microenvironment in mediating cancer survival and development. The concomitant targeted therapy and radiation is a new strategy in the treatment of NSCLC. A number of preclinical studies have demonstrated synergistic anti-tumor activity in the combination of EGFR inhibitors and radiotherapy in vitro and in vivo. In the present review, we discuss the rationale of the combination of EGFR inhibitors and radiotherapy in the treatment of NSCLC.

Abstract
Stored poultry manure can be a significant source of ammonia (NH) and greenhouse gases (GHGs), including nitrous oxide (NO), methane (CH), and carbon dioxide (CO) emissions. Amendments can be used to modify physiochemical properties of manure, thus having the potential to reduce gas emissions. Here, we lab-tested the single and combined effects of addition of reed straw, zeolite, and superphosphate on gas emissions from stored duck manure. We showed that, over a period of 46 d, cumulative NH emissions were reduced by 61 to 70% with superphosphate additions, whereas cumulative NO emissions were increased by up to 23% compared with the control treatment. Reed straw addition reduced cumulative NH, NO, and CH emissions relative to the control by 12, 27, and 47%, respectively, and zeolite addition reduced cumulative NH and NO emissions by 36 and 20%, respectively. Total GHG emissions (as CO-equivalents) were reduced by up to 27% with the additions of reed straw and/or zeolite. Our results indicate that reed straw or zeolite can be recommended as amendments to reduce GHG emissions from duck manure; however, superphosphate is more effective in reducing NH emissions.

Abstract
Previous DNA sequencing of BAC clones covering entire ovine MHC (OLA) region resulted in identification of approximately 130 functional genes in the region, of which 8 were predicted by computer software to be exclusively existed in sheep, but not in any other species known to date. In the present study, we successfully identified and cloned cDNA sequence of OaN2, OaN5, and OaN6 from representative sheep tissues, confirmed their existence in reality. The sequences obtained experimentally exactly identical to those predicted previously. The length of cDNA fragments for OaN2, OaN5, and OaN6 was 270 bp, 309 bp, and 205 bp, respectively, with GenBank accession number assigned as JF330782 (OaN2), JF330783 (OaN5), and JF330784 (OaN6). Northern analyses indicated that the mRNA transcripts of OaN2 were mainly seen in ovine mesenteric lymph nodes and spleen, while OaN5 was observed in only in mesenteric lymph nodes. In contrast, OaN6 transcripts were detected in all tissues except for liver and heart. Western blot showed that OaN2 protein expression level was detected in mesenteric lymph nodes, spleen, and liver, essentially consistent with that of mRNA transcripts. Immunohistochemistry analysis showed that OaN2 protein was highly expressed in ovine mesenteric lymph nodes, moderately expressed in, and not expressed in heart, liver, and pancreas, consistent with the results of Western blotting. The cloning and expression analysis of 3 novel genes provide a basis for revealing their specificities and would be helpful to further study of their expression profile and their potential functions.

Abstract
OBJECTIVE To elucidate the mechanism of angiogenesis after cerebral ischemia/reperfusion (I/R) in the aged rats by observing the changes in expressions of basic fibroblast growth factor (bFGF) and transformation growth factor-β1 (TGF-β1). METHODS Young Sprague-Dawley (SD) rats were classified into groups by random digits table, and aged SD rats were stratified by different body weight. Rats were randomly divided into groups of sham operation, ischemia (I) 3 hours, I/R 1, 3, 6, 12 days, with 6 rats in each group. Focal cerebral I/R model was reproduced by intraluminal filament technique. Microvessel density (MVD) of brain tissue, sum area of lumens were observed, and the expressions of bFGF protein, TGF-β1 protein and TGF-β1 mRNA were assessed with immunohistochemistry and hybridization in situ. RESULTS MVD in young model group began to increase at I 3 hours, peaking at I/R 6 days, maintained up to I/R 12 days. MVD in aged model group began to descend at I 3 hours and continued to I/R 12 days. Sum area of lumens in young model group increased markedly at I/R 1 day, gradually lowered at I/R 1-6 days, and increased obviously again at I/R 12 days. Sum area of lumens in aged model group reached peak at I/R 1 day, gradually decreased subsequently. MVD in aged sham operation group were higher than that in young sham operation group (6.88±1.60 vs. 5.50±1.53, P<0.01). MVD and sum area of lumens in aged model group at I/R 1, 3, 6, 12 days were lower than young model group. Expressions of bFGF protein, TGF-β1 protein in young and aged model group were both gradually up-regulated, all of them reaching peak at I/R 3 days, and lowered gradually at I/R 3-12 days subsequently. Expressions of bFGF protein (grey level) in both aged sham operation group and those of model group at I 3 hours, I/R 1, 3, 12 days were lower than those of young sham operation and those of the model group at the same time points (176.80±5.10 vs. 172.82±1.53, 171.81±2.43 vs. 167.85±2.41, 167.99±5.51 vs. 164.90±2.15, 152.98±4.11 vs. 150.75±1.11, 165.67±3.55 vs. 161.73±1.29, P<0.05 or P<0.01). Expressions of TGF-β1 protein (grey level) in both aged sham operation and those of model group at I 3 hours, I/R 1, 3, 6, 12 days were all lower than those of young sham operation and those of model group at the same time points (182.69±3.12 vs. 176.13±4.08, 176.89±2.30 vs. 170.56±7.47, 171.74±2.70 vs. 165.43±2.91, 157.17±5.20 vs. 150.43±4.28, 161.72±4.81 vs. 155.37±2.92, 167.69±2.18 vs. 160.28±3.59, all P<0.01). TGF-β1 mRNA expressions in both young model group and aged model group reached peak at I/R 1 day, gradually lowered subsequently. Expressions of TGF-β1 mRNA (gray level) in both aged sham operation and those of model group at I 3 hours, I/R 3, 6, 12 days were lower than those of young sham operation and also model group at the same time points (176.51±9.52 vs. 169.09±5.08, 176.75±5.74 vs. 165.36±4.78, 177.33±5.68 vs. 165.25±8.14, 178.46±4.91 vs. 170.51±4.29, 203.95±4.51 vs. 181.98±5.59, all P<0.01). CONCLUSION Angiogenesis is obviously weak after cerebral I/R in the aged, and the mechanism of which might be related to the down-regulation of expressions of bFGF protein, TGF-β1 protein and TGF-β1 mRNA. Aging factor may be one of the main reasons which induce the down regulation of expressions mentioned above.

Abstract
OBJECTIVE To study the effects of Naomaitong Recipe, a compound Chinese herbal medicine, on the expressions of nuclear factor-kappaB (NF-kappaB) and nitric-oxide synthases (NOSs) in brain tissue after focal cerebral ischemia reperfusion in aged rats and the dosage-effect relationship. METHODS We adopted the middle cerebral artery occlusion (MCAO) in aged rats as the focal cerebral ischemia model, with 3-hour ischemia and 12-day reperfusion, and observed the changes of the nerve dysfunction score, the water content of cerebral constitution and the expressions of NF-kappaB, heat-shock protein 70 (HSP70) and NOSs in cerebral cortex. RESULTS The nerve dysfunction score, the water content of cerebral constitution, the expressions of NF-kappaB, HSP70, neuronal nitric-oxide synthase (nNOS), endothelial nitric-oxide synthase (eNOS) and inducible nitric-oxide synthase (iNOS) in the untreated group were higher than those of the sham-operated group. The nerve dysfunction score, the water content of cerebral constitution, the expressions of NF-kappaB, iNOS and nNOS were lower, while the expressions of HSP70 and eNOS were higher in the high-, medium- and low-dose Naomaitong-treated groups and nimodipine-treated group than those of the untreated-group. The nerve dysfunction score and the expression of nNOS were lower, while the expression of eNOS was higher in the medium-dose Naomaitong-treated group than those of the nimodipine-treated group. The expressions of HSP70 and eNOS were higher, while the other indices were lower in the medium-dose Naomaitong-treated group than those of the low-dose Naomaitong-treated group. CONCLUSION Naomaitong Recipe can protect the brain cells from damage after focal cerebral ischemia reperfusion injury by adjusting the expressions of NF-kappaB, HSP70 and NOSs, and the medium-dose Naomaitong Recipe is more effective.

Abstract
In order to achieve fuzzy control of nitrification in a Sequencing Batch Reactor (SBR) brewery wastewater was used as the substrate. The effect of alkalinity on pH variation during nitrification was systematically studied, at the same time the variations of DO and ORP were investigated. Alkalinity and pH of the wastewater were adjusted by adding sodium bicarbonate at five levels and sodium hydroxide at two levels. Unadjusted wastewater was also studied. According to the results, variation of pH could be divided into rising type and descending type. When bicarbonate alkalinity was deficient or sufficient, the descending type happened. If alkalinity was deficient, the pH decreasing rate got slower when nitrification nearly stopped; if alkalinity was sufficient, at the end of nitrification pH turned from decrease to increase. This was the most common situation and pH could be used to control the end of nitrification. When alkalinity was excessive, the rising type happened, pH was increasing at nearly a constant rate during and after nitrification and could not be used to control the nitrification time, but if the aeration rate was moderate DO could be used to control the nitrification time. This situation seldom happened. Therefore the variation of pH could not only be used to control the nitrification time but also to judge whether the alkalinity was enough or not. On the basis of this, the fuzzy controller of nitrification in SBR was constructed. When discussing the influence of pH on nitrification rate the composition and concentration of alkalinity must be considered or else the results may be incomprehensive. And to some extent the influence of alkalinity on nitrification rate was more important than pH.

Abstract
In order to achieve fuzzy control of denitrification in a Sequencing Batch Reactor (SBR) brewery wastewater was used as the substrate. The effects of brewery wastewater, sodium acetate, methanol and andogenous carbon source on the relationships between pH, ORP and denitrification were investigated. Also different quantities of brewery wastewater were examined. All the results indicated that the nitrate apex and nitrate knee occurred in the pH and ORP profiles at the end of denitrification. And when carbon was the limiting factor, through comparing the different increasing rate of pH whether the carbon was enough or not could be known, and when the carbon should be added again could be decided. On the basis of this, the fuzzy controller for denitrification in SBR was constructed, and the on-line fuzzy control experiments comparing three methods of carbon addition were carried out. The results showed that continuous carbon addition at a low rate might be the best method, it could not only give higher denitrification rate but also reduce the re-aeration time as much as possible. It appears promising to use pH and ORP as fuzzy control parameters to control the denitrification time and the addition of carbon.

Abstract
A number of studies show that environmental stress conditions increase abscisic acid (ABA) and hydrogen peroxide (H2O2) levels in plant cells. Despite this central role of ABA in altering stomatal aperture by regulating guard cell ion transport, little is known concerning the relationship between ABA and H2O2 in signal transduction leading to stomatal movement. Epidermal strip bioassay illustrated that ABA-inhibited stomatal opening and ABA-induced stomatal closure were abolished partly by externally added catalase (CAT) or diphenylene iodonium (DPI), which are a H2O2 scavenger and a NADPH oxidase inhibitor respectively. In contrast, internally added CAT or DPI nearly completely or partly reversed ABA-induced closure in half-stoma. Consistent with these results, whole-cell patch-clamp analysis showed that intracellular application of CAT or DPI partly abolished ABA-inhibited inward K+ current across the plasma membrane of guard cells. H2O2 mimicked ABA to inhibit inward K+ current, an effect which was reversed by the addition of ascorbic acid (Vc) in patch clamping micropipettes. These results suggested that H2O2 mediated ABA-induced stomatal movement by targeting inward K+ channels at plasma membrane.

Abstract
Epidermal bioassay demonstrated that benzylamine, a membrane-permeable weak base, can mimick hydrogen peroxide (H2O2) to induce stomatal closure, and butyric acid, a membrane-permeable weak acid, can partly abolish the H2O2-induced stomatal closure. Confocal pH mapping with the probe 5-(and-6)-carboxy seminaphthorhodafluor-1-acetoxymethylester (SNARF-1-AM) revealed that H2O2 leads to rapid changes in cytoplasmic and vacuolar pH in guard cells of Vicia faba L, i. e. alkalinization of cytoplasmic areas occur red in parallel with a decrease of the vacuolar pH, and that butyric acid pretreatment can abolish alkalinization of cytoplasmic areas and acidification of vacuolar areas of guard cells challenged with H2O2. These results imply that the alkalinization of cytoplasm via efflux of cytosol protons into the vacuole in guard cells challenged with H2O2 is important at an early stage in the signal cascade leading to stomatal closure.

Abstract
The methods of confocal laser scanning microscopy (CLSM) and microinjection were used to study ABA-induced H2O2 in guard cells (Vicia faba), which were labeled with H2O2 specific probe-2, 7-dichlorofluorescin diacetate(H2DCFDA). The results indicated 100 U/mL catalase (CAT) could inhibit partly stomatal closure induced by ABA. 10(-3) mmol/L ABA could significantly induce H2O2 production in chloroplast in guard cells of Vicia faba following microinjection, and 100 U/mL CAT could partly abolish the effects following simultaneous microinjection of ABA and CAT. These suggest that H2O2 is possibly involved in ABA signaling leading to stomatal closure.

Abstract
The article describes the effectiveness of compatible application of heat-clearing and detoxifying drugs with blood circulation improving drugs to the animal model with endotoxemia and nonspecific inflammation. The compatible application reduces PGE2, endotoxin blood concentration and reduced viscosity of whole blood, decreases Evans blue extravasation volume and pes swelling percentage, increases serum cortisol content and enhances fibrinolytic activity. The experimental result shows that in most cases these two drugs work better when used in combination which implies that compatible application is more effective in detoxification, antiinflammation and inflammation recovery.

Abstract
The spatial distribution of the hippocampus-cerebellar projection and the connection between the projection area of hippocampus in the cerebellum and cerebellar nuclei were studied by means of electrophysiological and HRP labelling techniques. Polysynaptic responses of Purkinje cell's simple and complex spike in the lobule VI could be evoked by stimulation of the area CA1/CA3 of the dorsal hippocampus. These results suggest that there are polysynaptic projections from CA1 and CA3 areas of dorsal hippocampus to the lobule VI of cerebellar cortex, and the last relay fibers for these projections are mossy fiber and/or climbing fiber. It is also shown that this hippocampus-cerebellar projection predominantly terminates at the lobule VI of cerebellar cortex, 0.8-1.4 mm lateral to the midline. The projection from CA1 area is mainly contralateral, whereas the projection from CA3 area is mainly ipsilateral. The results with HRP labelling indicate that the projection area of hippocampus is an interpositus zone of the lobule VI. Reciprocal connections may exist between this cortical area and the interpositus nucleus.
