Abstract
AIM Para-aminosalicylic acid (PAS) is effective in the treatment of manganism-induced neurotoxicity (manganism). In this study we investigated the roles of P-glycoprotein (MDR1a) and multidrug resistance protein (MRP) in transporting PAS and its N-acetylated metabolite AcPAS through blood-brain barrier. METHODS MDR1a-null or wild-type mice were intravenously injected with PAS (200 mg/kg). Thirty minutes after the injection, blood samples and brains were collected, and the concentrations of PAS and AcPAS in brain capillaries and parenchyma were measured using HPLC. Both MDCK-MDR1 and MDCK-MRP1 cells that overexpressed P-gp and MRP1, respectively, were used in two-chamber Transwell transport studies in vitro. RESULTS After injection of PAS, the brain concentration of PAS was substantially higher in MDR1a-null mice than in wild-type mice, but the brain concentration of AcPAS had no significant difference between MDR1a-null mice and wild-type mice. Concomitant injection of PAS with the MRP-specific inhibitor MK-571 (50 mg/kg) further increased the brain concentration of PAS in MDR1a-null mice, and increased the brain concentration of AcPAS in both MDR1a-null mice and wild-type mice. Two-chamber Transwell studies with MDCK-MDR1 cells demonstrated that PAS was not only a substrate but also a competitive inhibitor of P-gp, while AcPAS was not a substrate of P-gp. Two-chamber Transwell studies with the MDCK-MRP1 cells showed that MRP1 had the ability to transport both PAS and AcPAS across the BBB. CONCLUSION P-gp plays a major role in the efflux of PAS from brain parenchyma into blood in mice, while MRP1 is involved in both PAS and AcPAS transport in the brain.

Abstract
AIM: To compare the effects of transthoracic and transabdominal hiatal approaches for the treatment of Siewert types Ⅱ and Ⅲ adenocarcinoma of the esophago-gastric junction.
METHODS: A total of 350 patients who were pathologically diagnosed with Siewert type Ⅱ or type Ⅲ adenocarcinoma of the esophago-gastric junction and underwent surgical treatment at our hospital were included, of whom 148 received surgery via the transthoracic approach (transthoracic group) and 202 received surgery via transabdominal hiatal approach (transabdominal hiatal group). Intraoperative parameters, postoperative recovery and complications were compared between the two groups of patients.
RESULTS: The number of patients receiving multi-visceral resection was more in the transabdominal hiatal group than in the transthoracic group (χ2 = 12.744, P = 0.002), but the operative time, intraoperative blood loss, length of esophageal resection and number of patients receiving transfusion were lower in the transabdominal hiatal group (P = 0.039, 0.011, 0.009, 0.000). Postoperative pain score and antibiotic use duration in the transthoracic group were significantly higher than those in the transabdominal hiatal group (t = 5.879, 9.388, P = 0.005, 0.000), and the length of hospital stay, postoperative hospitalization cost, reoperation, and readmission rate showed the same trend (P = 0.027, 0.021, 0.048, 0.025). Although the rates of abdominal cavity infection and anastomotic stenosis showed no statistical differences between the two groups (χ2 = 1.524, 0.149, P = 0.217, 0.700), the rates of lung infection, postoperative bleeding and anastomotic leakage were significantly higher in the transthoracic group than in the transabdominal hiatal group (χ2 = 9.031, 9.031, 4.215, P = 0.003, 0.040, 0.024).
CONCLUSION: Patients with type Ⅱ or Ⅲ adenocarcinoma of the esophago-gastric junction treated via the transabdominal hiatal approach suffered from less intraoperative trauma and had quicker recovery and lower incidence of complications.

Abstract
This study aimed to investigate the value of magnetic resonance spectroscopy (MRS) imaging in assessing nasopharyngeal carcinoma radiotherapy during the early delayed reaction period. Eighty cases of nasopharyngeal cancer treated with radiotherapy within the same period underwent MRS imaging before or after radiotherapy. Of the 80 cases, 47 underwent MRS imaging on the 3rd, 4th, 6th, and 12th months after radiotherapy. The trends of the primary metabolite concentration at different time points were monitored and compared with the corresponding data after radiotherapy. Repeated measures analysis of variance was performed. At the end of radiotherapy, the N-acetyl aspartate (NAA)/creatine (Cr), choline (Cho)/Cr, and NAA/Cho ratios were reduced to the lowest levels after 3 months. However, increasing trends were observed from the 4th to the 12th month. On the 12th month, stable levels were reached with statistically significant differences (F = 316.02, 53.84, 286.68; P < 0.01). MRS reflected the radiation injury-repair process in the brain of a nasopharyngeal cancer patient during early delayed reaction. This non-invasive monitoring of changes in brain tissue metabolite concentrations provides valuable information for prognosis.

Abstract
The objective of the present study was to examine the antitumor efficacy of the ethanol extract from Artemisia dracunculus as well as the compounds isolated from it on cultured EC‑109 esophageal squamous cell carcinoma (ESCC) cells. Apoptotic activities of the compounds were also studied using flow cytometry. EC‑109 esophageal cancer cells were treated with varying concentrations of compounds 1-7 isolated from the plant as well as the ethanol extract of Artemisia dracunculus. The cytotoxicity was evaluated by MTT assay and the apoptotic studies of the compounds were determined using flow-cytometry. Effect on mitochondrial membrane potential loss ΛΨ m induced by compounds 2 and 4 was also studied in these cells. Bioassay-guided fractionation of the ethanol extract from the shoot and root parts of Artemisia dracunculus led to the isolation of 7-methoxycoumarin (1), scopoletin (2), dracumerin (3), sakuranetin (4), elimicin (5), davidigenin (6) and 6-methoxycapillarisin (7). All the compounds as well as the extract showed mild to potent cell proliferation inhibitory activities against the esophageal cell line. Sakuranetin and 6-methoxycapillarisin were found to have the most potent effects in inhibiting the cell proliferation. The 2 potent compounds, sakuranetin and 6-methoxycapillarisin were evaluated for their effects on cell cycle phase distribution (DNA damage) as well as their effects on mitochondrial membrane potential loss ΛΨ m. Both compounds induced DNA damage as well as mitochondrial membrane potential loss in esophageal cancer cells. The study suggests that compounds, Sakuranetin and 6-methoxycapillarisin isolated from Artemisia dracunculus possess potent anticancer effects by inducing DNA damage in these cells.

Abstract
Literature data indicate that bone is a major storage organ for manganese (Mn), accounting for 43% of total body Mn. However, the kinetic nature of Mn in bone, especially the half-life (t(1/2)), remained unknown. This study was designed to understand the time-dependence of Mn distribution in rat bone after chronic oral exposure. Adult male rats received 50 mg Mn/kg (as MnCl2) by oral gavage, 5 days per week, for up to 10 weeks. Animals were sacrificed every 2 weeks during Mn administration for the uptake study, and on day 1, week 2, 4, 8, or 12 after the cessation at 6-week Mn exposure for the t(1/2) study. Mn concentrations in bone (MnBn) were determined by AAS analysis. By the end of 6-week's treatment, MnBn appeared to reach the steady state (T(ss)) level, about 2-3.2 fold higher than MnBn at day 0. Kinetic calculation revealed t(1/2)s of Mn in femur, tibia, and humerus bone of 77 (r=0.978), 263 (r=0.988), and 429 (r=0.994) days, respectively; the average t(1/2) in rat skeleton was about 143 days, equivalent to 8.5 years in human bone. Moreover, MnBn were correlated with Mn levels in striatum, hippocampus, and CSF. These data support MnBn to be a useful biomarker of Mn exposure.

Abstract
AIMS Biliary tract obstruction is a common clinical lesion. However, the effect of biliary tract obstruction on intestinal secretion is poorly understood. In this study, we made an investigation on intestinal HCO3 (-) and Cl(-) secretions in an experimental model of murine biliary duct ligation. METHODS Murine intestinal mucosal HCO3 (-) and Cl(-) secretions were examined in vitro in Ussing chambers by pH-stat and short-circuit current (Isc ) techniques. The mRNA and protein expressions of the cystic fibrosis transmembrane conductance regulator (CFTR) and the Na(+) -K(+) -2Cl(-) cotransporter (NKCC1) were analysed by real-time PCR, western blot and immunohistochemistry. RESULTS Basal Cl(-) secretion and forskolin-stimulated duodenal and jejunal mucosal HCO3 (-) and Cl(-) secretions in mice with common biliary duct ligation were markedly elevated, compared with controls (P < 0.05 and P < 0.01). Further experiments showed that basal Cl(-) secretion and forskolin-stimulated duodenal and jejunal mucosal HCO3 (-) and Cl(-) secretions in mice with external bile drainage were also markedly elevated. CFTRinh -172 inhibited forskolin-stimulated HCO3 (-) and Cl(-) secretions. The mRNA and protein expression levels of CFTR and NKCC1 in the intestinal mucosa with both biliary duct ligation and external bile drainage were markedly higher than those in controls (P < 0.001). Bile acid administration restored the changes in function and expression of CFTR and NKCC1 in the intestinal mucosa. CONCLUSION Bile deficiency in the intestine up-regulates the expressions of intestinal mucosal CFTR and NKCC1 and enhances intestinal mucosal HCO3 (-) and Cl(-) secretion capacity, which contributes to the understanding of intestinal physiological function for patients with biliary duct obstruction.

Abstract
The objective of this study was to explore the feasibility and methods of screening the residual normal ovarian tissue adjacent to orthotopic ovarian carcinomas in nude mice. Human epithelial ovarian cancer cells (OVCAR3) were subcutaneously implanted for a tumor source and ovarian orthotopic transplantation. The cancer tissue, proximal paraneoplastic tissue, middle paraneoplastic tissue, remote paraneoplastic tissue, and normal ovarian tissue were removed. CK-7, CA125, p53, survivin, MMP-2, and TIMP-2 expression was detected by reverse transcription polymerase chain reaction. We obtained 35 paraneoplastic residual ovarian tissues with normal biopsies from 40 cases of an orthotopic epithelial ovarian carcinoma model (87.5%). CK-7, CA125, p53, survivin, MMP-2, and TIMP-2 expression was lower in proximal paraneoplastic tissue than in cancer tissue (P < 0.05) and higher than in middle and remote paraneoplastic tissue (P < 0.01). There was no statistically significant difference between the expression of these genes in middle and proximal paraneoplastic tissue as well as among residual normal ovarian tissues with different severity (P > 0.05). In ovarian tissues of 20 normal nude mice, the expression of CK- 7, CA125, p53, survivin, MMP-2, and TIMP-2 was negative. Overall, the expression levels of CK-7, CA125, p53, survivin, MMP-2, TIMP-2, and other molecular markers showed a decreasing trend in the non-cancer tissue direction. The expression levels can be used as standards to screen residual normal ovarian tissue. We can obtain relatively safe normal ovarian tissues adjacent to epithelial ovarian cancer.

Abstract
Acute alcohol intoxication affects cerebellar motor regulation possibly by altering the transfer and integration of external information in cerebellar cortical neurons, resulting in a dysfunction of cerebellar motor regulation or a cerebellar atexia. However, the synaptic mechanisms of ethanol induced impairments of sensory information processing in cerebellar cortical neurons are not fully understand. In the present study, we used electrophysiological and pharmacological methods to study the effects of ethanol on the sensory stimulation-evoked responses in cerebellar granule cells (GCs) in vivo in urethane anesthetized mice. Air-puff stimulation of the ipsilateral whisker-pad evoked stimulus-on (P1) and stimulus-off responses (P2) in GCs of cerebellar Crus II. Cerebellar surface perfusion of ethanol did not alter the onset latency of the sensory stimulation-evoked responses, but reversible reduced the amplitude of P1 and P2. The ethanol-induced reduction of the GCs sensory responses was concentration-dependent. In the presence of ethanol, the mean half-width, area under curve, rise Tau and decay Tau of P1 were significantly decreased. Blockade of gamma-aminobutyric acid type A (GABA(A)) receptors activity induced an increase in amplitude of P1, and abolished the ethanol induced inhibition of the GCs sensory responses. These results indicate that ethanol inhibits the tactile evoked responses in cerebellar GCs through enhancement of GABA(A) receptors activity.

Abstract
OBJECTIVE The aim of this study was to compare the characteristics of two orthotopic xenograft models established with human epithelial ovarian cancer solid tumor tissue slices and human ovarian carcinoma cell line OVCAR-3. MATERIALS AND METHODS Tumor tissues and cell line OVCAR3 of human epithelial ovarian cancer were grown in subcutaneous tissue and the subcutaneous tumor source was fetched and inoculated in ovarian capsule of nude mice under microscope to establish the orthotopic implantation model. At four and eight weeks after modeling, the orthotopic tumor formation rate, tumor diameter, metastasis rate outside the ovary, incidence rate of ascites, and CA125 levels in the two models were observed. RESULTS The orthotopic tumor formation rate in the solid tumor slices group (60.0%) was significantly lower than that in the cell line group (85.0%, p < 0.05). However, the tumor diameter, metastasis rate outside the ovary, incidence rate of ascites, and CA125 levels in the solid tumor slices group (2.4 +/- 0.61 cm, 75.0%, 50.0%, and 80.13 +/- 11.26 U/ml, respectively) were remarkably higher than those in the cell line group (1.6 +/- 0.53 cm, 52.9%, 29.4%, and 36.5 +/- 6.71 U/ml, respectively) (p < 0.05, respectively). CONCLUSION There are differences between the two orthotopic xenograft models established with human epithelial ovarian cancer solid tumor tissue slices and human ovarian carcinoma cell line OVCAR-3. The biological characteristics of the solid tumor slices model are more similar to human ovarian cancer.

Abstract
OBJECTIVES To investigate the effect of multimodality treatment of advanced paediatric hepatoblastoma and the factors affecting the prognosis. PATIENTS AND METHODS 35 childhood patients were treated with multimodality treatments consisting of chemotherapy, surgery, interventional therapy, and autologous peripheral blood stem cell transplantation. Patients were followed up every month. RESULTS 33 patients completed the follow-up, of which 17 were in complete remission, 5 were in partial remission, 1 case got worse, and 10 died. The remission rate was 66.7% (22/33), and the overall survival rate was 69.7% (23/33). 1 patient with advanced hepatoblastoma got high-dose chemotherapy combined with autologous peripheral blood stem cell transplantation (APBSCT) treatment, and a primary lesion by 18 x 15 x 9 cm reduced to 10 x 8 x 4 cm. Remote metastases significantly alleviated, and partial remission reached six months. The overall survival was 9 months after transplantation. Patients with the mixed phenotype of hepatoblastoma had a worse prognosis than with the epithelial phenotype (p < 0.001), and patients in stage IV had a lower survival rate than in stage III (p < 0.001). CONCLUSIONS Multimodality treatment can effectively improve remission rate and prolong the survival of children with the advanced hepatoblastoma. In addition, alpha-fetoprotein (AFP), hepatoblastoma pathological classification and staging are of great use in prediction of prognosis.

Abstract
Abstract
Purpose
To evaluate the effect of adjuvant chemotherapy (CTX) on acute and late toxicity among women undergoing hypofractionated radiation therapy (HRT) following breast-conserving therapy and to assess the relative impact of breast size.
Materials and Methods
In this retrospective study, patients treated with HRT to the whole breast (42.4 Gy in 16 fractions) followed by a boost (9.6 Gy in 4 fractions) between 2005 and 2009 were evaluated for inclusion. Early-stage (I-II) patients who underwent post-lumpectomy CTX prior to HRT were included. Patients who underwent neoadjuvant CTX were excluded; node positive patients and larger-breasted women (chest wall separation of >25 cm) were included. Toxicity evaluations during HRT and at 2-4 weeks, 3, 6, 9 months, and at yearly intervals were collected and graded using the RTOG Acute and Late Toxicity scales. Relevant data was available in 43 women. The median age was 60 years (35 – 71), and women were primarily of African American (55.8%) and Hispanic (27.9%) ethnicity. The majority of patients had high-grade lesions (69.8%), were Stage II (60.4%), and had T1 primaries (55.8%). Slightly more than half the patients (53.5%) were ER+; 20% were Her2 positive, and 37.2% were triple negative. Thirty-three (76.7%) were treated in the prone position. Lumpectomy cavity boosts were given via photons (58.2%) or electrons. Chemotherapy regimens included ACT (Adriamycin, Cytoxan, and Taxol) in 33/43 (76.7%) and CMF (Cytoxan, methotrexate, and 5FU) in the remainder. The median interval between completion of adjuvant CTX and the start of HRT was 41 days. The median BMI of the women was 31.8 (18.2 – 44.4; normal weight defined as BMI of 18.5 – 24.9); 11 women (25.6%) had a separation of more than 25 cm, and the median PTV volume was 1353cc (589-4213). STATA v 11 was used for all statistical analyses.
Results
The median cosmetic evaluation follow-up was 33.5 months. Forty women (93%) experienced an acute toxicity. The majority of these (31/40) were Grade 1 dermatitis with the remainder Grade 2 dermatitis (moist desquamation). There were no reported acute toxicities > Grade 2. Thirteen women (30.2%) were reported to have a late toxicity: Grade 1 skin in 9, Grade 1 subcutaneous tissue in 5, and Grade 2 subcutaneous in 2 of the 9 women with Grade 1 skin. There were no late toxicities > Grade 2. The acute and late toxicity rates of our main cohort and those with larger breasts were similar to those reported in the literature. On univariate analysis, there was no significant correlation (p>0.05) between toxicity and age, race, BMI, separation, tumor size, grade, or hormone receptor status, CTX regimen, and treatment position and duration. There was, however, a trend toward increased toxicity with a shorter interval between CTX completion and HRT start (p = 0.052).
Conclusions
The addition of adjuvant chemotherapy to the treatment regimen of breast conservation using HRT does not appear to lead to worse cosmetic outcomes. In addition, larger-breasted women, excluded from prior reports on HRT, were at no increased risk of acute or late toxicity. We found a trend toward significance suggesting that shorter intervals between CTX and HRT may be associated with increased toxicity.

Abstract
Herein, we report the design, syntheses and in vitro anti-microbial activity of two series of rhodanines with chalcone moiety. Anti-microbial tests showed that some of the synthesized compounds exhibited good inhibition (MIC = 1-8 µg/mL) against multi-drug-resistant Gram-positive organisms, including methicillin resistant and quinolone-resistant Staphylococcus aureus, in which the compound 4g was found to be the most potent with minimum inhibitory concentration (MIC) value of 1 µg/mL against two methicillin-resistant S. aureus.

Abstract
Parasitic plants can adversely influence the growth of their hosts by removing resources and by affecting photosynthesis. Such negative effects depend on resource availability. However, at varied resource levels, to what extent the negative effects on growth are attributed to the effects on photosynthesis has not been well elucidated. Here, we examined the influence of nitrogen supply on the growth and photosynthesis responses of the host plant Mikania micrantha to infection by the holoparasite Cuscuta campestris by focusing on the interaction of nitrogen and infection. Mikania micrantha plants fertilized at 0.2, 1 and 5 mM nitrate were grown with and without C. campestris infection. We observed that the infection significantly reduced M. micrantha growth at each nitrate fertilization and more severely at low than at high nitrate. Such alleviation at high nitrate was largely attributed to a stronger influence of infection on root biomass at low than at high nitrate fertilization. However, although C. campestris altered allometry and inhibited host photosynthesis, the magnitude of the effects was independent of nitrate fertilizations. The infection reduced light saturation point, net photosynthesis at saturating irradiances, apparent quantum yield, CO2 saturated rate of photosynthesis, carboxylation efficiency, the maximum carboxylation rate of Rubisco, and maximum light-saturated rate of electron transport, and increased light compensation point in host leaves similarly across nitrate levels, corresponding to a similar magnitude of negative effects of the parasite on host leaf soluble protein and Rubisco concentrations, photosynthetic nitrogen use efficiency and stomatal conductance across nitrate concentrations. Thus, the more severe inhibition in host growth at low than at high nitrate supplies cannot be attributed to a greater parasite-induced reduction in host photosynthesis, but the result of a higher proportion of host resources transferred to the parasite at low than at high nitrate levels.

Abstract
OBJECTIVE To explore the personality-adjusting effect of electro-acupuncture treatment for depression and compared this treatment with paroxetine treatment. METHODS A non-blinded, randomized controlled trial was adopted. Sixty depressed patients, who met trial criteria, were randomly assigned to the treatment and the control groups. In the treatment group, electro-acupuncture treatment was used, and paroxetine treatment was used in the control group. During the 24-week study period, 12 patients dropped out and 48 patients completed the study. The Minnesota Multiple Personality Inventory (MMPI) was adopted as the evaluation tool. At the same time, the Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS) and Montgomery-Asberg Depression Rating Scale (MADRS) were used to evaluate the psychological state. Evaluations were done before and after treatment. RESULTS After treatment, patients' psychological state improved significantly in both groups (P<0.01). For the treatment group, within-group comparison between baseline and after 24 weeks of treatment showed that severity of depression had significantly decreased (P<0.01). MADRS and SDS scores decreased significantly (P<0.05) and MMPI subscale scores for hypochondriasis, depression, psychopathic deviate, psychasthenia, social introversion and fake decreased significantly (P<0.05). For the control group, severity of depression also decreased significantly. MADRS and SDS scores decreased significantly (P<0.05); and MMPI subscale scores for hypochondriasis, depression, hysteria, paranoia, and psychasthenia decreased significantly (P<0.05). Between-group comparison demonstrated that for the MMPI subscales paranoia and social introversion, the decrease of score was greater in the treatment group than in the control group (P<0.05). However, there were no other significant differences between the control group and the treatment group. CONCLUSION Electro-acupuncture is effective for treating depression and affects personality traits.

Abstract
Excess body weight (body mass index >25 kg/m(2)) is common in patients with esophageal adenocarcinoma. In this study, a meta-analysis was performed by searching PubMed, Cochrane Library, EMBASE, and Science Direct databases from 1960 to June 2012. Data were extracted from studies comparing survival in obese (body mass index >30), overweight (body mass index 25-29), and normal-weight (body mass index 20-24) patients undergoing esophagectomy. A total of six studies with 1988 cases were suitable for this global meta-analysis. Compared with patients of normal weight, the hazard ratio of postoperational survival for overweight and obese patients was 0.79 (95% confidence interval 0.65-0.95, P = 0.108) and 0.80 (95% confidence interval 0.68-0.93, P = 1.00), respectably. Taken together, the excess body weight did not have the value of predicting survival for patients with esophageal adenocarcinoma.

Abstract
Mikania micrantha is a successful invasive weed in many parts of the world. Twelve polymorphic microsatellite loci were isolated and characterized from an AC-enriched genomic library of this species. Twenty-eight individuals from one population in Dongguan were tested for polymorphism. The average allele number of these microsatellites was three per locus, ranging from two to five. The expected and observed heterozygosities ranged from 0.275 to 0.742, and from 0.250 to 1.000, respectively. These microsatellite markers can be applied to study the population genetics in the native and invasive ranges of this species, and to trace its invasion history.

Abstract
The ethylene response factor (ERF) family are members of the APETALA2 (AP2)/ERF transcription factor superfamily; they are known to play an important role in plant adaptation to biotic and abiotic stress. ERF genes have been studied in Arabidopsis, rice, grape, and maize; however, there are few reports of ERF genes in sorghum. We identified 105 sorghum ERF (SbERF) genes, which were categorized into 12 groups (A-1 to A-6 and B-1 to B-6) based on their sequence similarity, and this new method of classification for ERF genes was then further characterized. A comprehensive bioinformatic analysis of SbERF genes was performed using a sorghum genomic database, to analyze the phylogeny of SbERF genes, identify other conserved motifs apart from the AP2/ERF domain, map SbERF genes to the 10 sorghum chromosomes, and determine the tissue-specific expression patterns of SbERF genes. Gene clustering indicates that SbERF genes were generated by tandem duplications. Comparison of SbERF genes with maize ERF homologs suggests lateral gene transfer between monocot species. These results can contribute to our understanting of the evolution of the ERF gene family.

Abstract
OBJECTIVES To investigate the possibility of culturing dendritic cells (DCs) and cytokine-induced killer (CIK) cells, obtained at initial diagnosis of AML in elderly patients, and to investigate the safety and efficacy of treatment with autologous DCs and CIK cells when administered to these patients in combination with low-dose chemo therapy. METHODS DCs and CIK cells obtained at initial diagnosis of AML in elderly patients were cultured and used in combination with low-dose chemo therapy to treat these patients (immunotherapy group). Elderly patients with AML treated only with low-dose chemotherapy served as the control. Before treatment and on day 7 after treatment with autologous DCs and CIK cells, T cell subsets and cytokine levels were evaluated in the immunotherapy group. RESULTS A total of 21 elderly patients with AML were included in the immunotherapy group and 23 in the control group. The clinical efficacy in the immunotherapy group was greater than in the control group. The percentages of T cell subsets and cytokine levels after immunotherapy treatment were significantly higher than before the treatment. CONCLUSION Immuno therapy with autologous DCs and CIK cells was found to be a promising candidate for treatment of AML in elderly patients.

Abstract
With an intention to synergize the anti-bacterial activity of 5-aryloxy pyrazole and rhodanine derivatives, eight series of hybrid compounds have been synthesized and evaluated for their antibacterial activity. The majority of the synthesized compounds showed good inhibitory activity against selected methicillin resistant and quinolone-resistant Staphylococcus aureus (MRSA, QRSA) with minimum inhibitory concentration (MIC) values in the range of 1-32 μg/mL. The cytotoxicity test suggests that these compounds exhibited in vitro antibacterial activity at non-cytotoxic concentrations. These studies therefore suggest that rhodanine-based 5-aryloxy pyrazoles are interesting scaffolds for the development of novel Gram-positive antibacterial agents.

Abstract
OBJECTIVE Nude mice with orthotopic transplantation of human ovarian epithelial cancer were used to investigate screening criteria for paraneoplastic normal ovarian tissue and the security of the freezing and thawing for ovarian tissue transplantation. METHODS Expression of CK-7, CA125, P53, survivin, MMP-2/TIMP- 2 in paraneoplastic normal ovarian tissues were detected by RT-PCR as well as immunohistochemistry. The tissues of the groups with all negative indicators of RT-PCR, all negative indicators of immunohistochemistry, negative expression of CK-7, CA125 and survivin, positive expression of CK-7, CA125 and survivin, cancer tissues and normal ovarian tissues of nude mice were used for freezing and thawing transplantation, to analyze overt and occult carcinogenesis rates after transplantation. RESULTS When all indicators or the main indicators, CK-7, CA125 and survivin, were negative, tumorigenesis did not occur after transplantation. In addition the occult carcinogenesis rate was lower than in the group with positive expression of CK-7, CA125 and survivin (P<0.01). After subcutaneous and orthotopic transplantation of ovarian tissues, rates did not change (P>0.05). There was no statistical significance among rates after transplantation of ovarian tissues which were obtained under different severity conditions (P>0.05). CONCLUSION Negative expression of CK-7, CA125 and survivin can be treated as screening criteria for security of ovarian tissues for transplantation. Immunohistochemical methods can be used as the primary detection approach. Both subcutaneous and orthotopic transplantation are safe. The initial severity does not affect the carcinogenesis rate after tissue transplantation. Freezing and thawing ovarian tissue transplantation in nude mice with human epithelial ovarian carcinoma is feasible and safe.

Abstract
The herbal ingredients of isocorydine and protopine were isolated from Dactylicapnos scandens. This study was aimed at developing a liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) method to quantify isocorydine and protopine in rat plasma and tissues for pharmacokinetic, tissue distribution and excretion studies. Biological samples were processed with ethyl acetate extraction, and corydaline was chosen as the internal standard (IS). The analytes were separated by a C(18) column and detected with a triple quadrupole mass spectrometer using positive ion ESI in the multiple reaction monitoring (MRM) mode. The MS/MS ion transitions monitored were m/z 342.0→278.9 for isocorydine, 354.1→188.0 for protopine and 370.0→192.0 for IS, respectively. Excellent linearity was observed over the concentration range between 10 and 3000 ng/mL for isocorydine and 10-300 ng/mL for protopine. The lower limit of quantification (LLOQ) was 10 ng/mL for both isocorydine and protopine. This novel method was rapid, accurate, high sensitive and high selective. It was successfully applied to the pharmacokinetic, tissue distribution and excretion studies of D. scandens. These preclinical data of D. scandens would be useful for the clinical reference.

Abstract
BACKGROUND We used a model of vascularized thymus lobes as a whole isolated organ transplantation in rats. MATERIALS AND METHODS Male Fisher rats (F344, RT11v1; n = 10) and male homozygous Rowett nude rats (rnu/rnu; n = 10) were used as donors and recipients, respectively. Both vascular lobes of the thymus as a whole isolated organ were heterotopically transplanted to the neck of recipients. The right common carotid artery of the donor thymus was anastomosed end-to-end to the homonymous artery of the recipient. The anterior vena cava and the left brachiocephalic vein of the donor thymus were anastomosed end-to-side to the right and left external jugular veins of the recipient, respectively. Histological examination was used to monitor graft viability; graft function was assessed using flow cytometry (FCM) and immunologic effects by skin grafts in vivo. RESULTS All recipients survived. Preparation of the donors and recipients took 35.6 ± 5.5 minutes and 60.3 ± 15.1 minutes, respectively. The blood supply to the thymus graft was patent. Histology of the thymus on postoperative days 14, 56, and 112 revealed viable grafts with preserved microarchitecture. FCM analysis showed 37.18 ± 11.1% CD3+ T cells at day 21 after transplantation. Skin grafts from F344 and Rowett rats survived 8-10 and more than 30 days, respectively, whereas all third-party Sprague Dawley grafts were rejected within 5 days. CONCLUSION We developed a novel model of isolated, direct vascularized whole thymus transplantation in nude rats, in which both lobes of the fully vascularized thymus were harvested en bloc for successful transplantation.

Abstract
Previous studies in humans and animals have suggested a possible association between lead (Pb) exposure and the etiology of Alzheimer's disease (AD). Animals acutely exposed to Pb display an over-expressed amyloid precursor protein (APP) and the ensuing accumulation of beta-amyloid (Aβ) in brain extracellular spaces. This study was designed to examine whether in vivo Pb exposure increased brain concentrations of Aβ, resulting in amyloid plaque deposition in brain tissues. Human Tg-SWDI APP transgenic mice, which genetically over-express amyloid plaques at age of 2-3 months, received oral gavages of 50mg/kg Pb acetate once daily for 6 weeks; a control group of the same mouse strain received the same molar concentration of Na acetate. ELISA results revealed a significant increase of Aβ in the CSF, brain cortex and hippocampus. Immunohistochemistry displayed a detectable increase of amyloid plaques in brains of Pb-exposed animals. Neurobehavioral test using Morris water maze showed an impaired spatial learning ability in Pb-treated mice, but not in C57BL/6 wild type mice with the same age. In vitro studies further uncovered that Pb facilitated Aβ fibril formation. Moreover, the synchrotron X-ray fluorescent studies demonstrated a high level of Pb present in amyloid plaques in mice exposed to Pb in vivo. Taken together, these data indicate that Pb exposure with ensuing elevated Aβ level in mouse brains appears to be associated with the amyloid plaques formation. Pb apparently facilitates Aβ fibril formation and participates in deposition of amyloid plaques.

Abstract
Although diet composition has been implicated as a major factor in the etiology of various gastrointestinal diseases, conclusive evidence remains elusive. This is particularly true in diseases such as necrotizing enterocolitis where breast milk as opposed to commercial formula appears to confer a "protective effect" to the "immature gut." Yet the mechanism by which this occurs continues to remain speculative. In the present study we hypothesize that the basic chemical composition of diet fundamentally selects for specific intestinal microbiota which may help explain disparate disease outcome and therapeutic direction. Complimentary animal and human studies were conducted on young piglets (21 d.)(n = 8) (IACUC protocols 08070 and 08015) and premature infants (adjusted gestational age 34-36 weeks) (n = 11) (IRB Protocol 15895A). In each study, cecal or stool contents from two groups (Breast milk-fed (BF) vs. Formula-fed (FF)) were analyzed by gas chromatography/mass spectrometry (GC/MS) and comprehensive metabolic profiles generated and compared. Concurrently, bacterial community structure was assayed and respective representative microbiota of the groups determined by 16S rRNA gene amplicon pyrosequencing. Statistical modeling and analysis was done using SIMCA-P+ and R software. GC/MS metabolomics identified clear differences between BF and FF groups in the intestinal environment of piglets and humans. Sugars, amino-sugars, fatty acids, especially unsaturated fatty acids, and sterols were identified as being among the most important metabolites for distinguishing between BF and FF groups. Joint analysis of microbiota and metabolomics pinpointed specific sets of metabolites (p < 0.05) associated with the dominant bacterial taxa. The chemical composition of diet appears to have a significant role in defining the microbiota of the immature gut. Tandem analysis of intestinal microbial and metabolic profiles is potentially a powerful tool leading to better understanding of the role of diet in disease perhaps even leading to specific strategies to alter microbial behavior to improve clinical outcome.

Abstract
AIMS Ouabain has been reported to increase the secretion of atrial natriuretic peptide (ANP) in vitro. However, the mechanism by which ouabain increases ANP secretion is not well known. Therefore, the purpose of the present study was to investigate the underlying mechanism of ouabain-stimulated ANP secretion. MAIN METHODS A perfused beating rabbit atrial model was used. The ANP and ET-1 levels in the atrial perfusates were measured by radioimmunoassays. KEY FINDINGS Ouabain (1.0, 3.0 and 6.0 μmol/L) significantly increased atrial ANP secretion in a dose-dependent manner, while the endothelin (ET)-1 levels were increased by the higher doses (3.0 and 6.0 μmol/L) of ouabain. Ouabain-increased atrial ET-1 release was blocked by PD98059 (30.0 μmol/L), an inhibitor of mitogen-activated protein kinase (MAPK). Nifedipine (1.0 μmol/L), an inhibitor of L-type Ca(2+) channels, completely abolished ouabain-increased ANP secretion without changing the ouabain-induced atrial dynamics. KB-R7943 (3.0 μmol/L), an inhibitor of Na(+)-Ca(2+) exchangers, completely blocked the effects of ouabain-increased atrial dynamics, but did not modulate ouabain-increased ANP secretion. ET-1 significantly stimulated atrial ANP release in a dose-dependent manner. The effects of ET-1 and ouabain on ANP secretion were completely blocked by BQ788 (0.3 μmol/L), an inhibitor of ET-1 type B (ET(B)) receptors, but not by BQ123 (0.3 μM), an inhibitor of ET-1 type A receptors. Ouabain-increased atrial ANP secretion was blocked by PD98059 and indomethacin (30.0 μmol/L), an inhibitor of cyclooxygenase. SIGNIFICANCE Ouabain significantly stimulated atrial ANP secretion via an ET-1-ET(B) receptor-mediated pathway involving MAPK signaling pathway activation and prostaglandin formation.
