Abstract
OBJECTIVE Lung cancer is a common tumor in the clinic. Hypoxia is an important biological characteristic in the solid malignant tumor. MiRNA participates in cell proliferation, differentiation, and apoptosis. This study tested hypoxia-inducible factor 1-α (HIF-1α) in lung cancer patients and analyzed the microRNA-15a (miR-15a) expression in A549 cells under different local hypoxia microenvironments. PATIENTS AND METHODS A total of 40 non-small cell lung cancer (NSCLC) patients in First Affiliated Hospital of Zhengzhou University between Jan 2015 and Jan 2016 were involved in this study. The serum and tissue samples of lung cancer were collected. Serum HIF-1α level was tested by enzyme-linked immunosorbent assay (ELISA) assay. HIF-1α expression in tissue was evaluated by using the immunohistochemistry. A549 cells were cultured under normoxic, hypoxic, and anaerobic environment, respectively. HIF-1α mRNA and miR-15a levels were determined by RT-PCR. RESULTS HIF-1α levels were up-regulated in serum and tissue (p<0.05). HIF-1α mRNA increased, while miR-15a down-regulated in A549 from hypoxia and anaerobic groups compared with control (p<0.05). HIF-1α shRNA transfection significantly reduced HIF-1α and elevated miR-15a level (p<0.05). MiR-15a shRNA transfection exhibited no statistical impact on HIF-1α expression (p>0.05). CONCLUSIONS HIF-1α highly expressed in lung cancer patients. MiR-15a levels were down-regulated in A549 cells under hypoxia and anaerobic conditions.

Abstract
Cryptorchidism is the most common congenital anomaly in male children. Its aetiology remains unknown in the majority of cases. Because HOXA11 plays a vital role in regulating testicular descent, genetic variants in HOXA11 genes may contribute to the risk of cryptorchidism. In this study, mutation analysis was performed on the HOXA11 gene in a cohort of 89 patients with cryptorchidism. Furthermore, an association analysis of the HOXA11 tag single nucleotide polymorphism rs6461992 was performed in 168 patients with unilateral cryptorchidism and 193 controls. No pathogenic mutations were found. A significant difference in genotype and allele distribution was detected between cases and controls (p = .029 and .022 respectively). These results suggest that mutations in the coding sequence of HOXA11 might not be a common cause of cryptorchidism, while common polymorphisms in the HOXA11 gene might contribute to the risk of developing unilateral cryptorchidism.

Abstract
Pharmacokinetic–pharmacodynamic (PK/PD) integration and modelling were used to predict dosage schedules of oxytetracycline for two pig pneumonia pathogens, Actinobacillus pleuropneumoniae and Pasteurella multocida. Minimum inhibitory concentration (MIC) and mutant prevention concentration (MPC) were determined in broth and porcine serum. PK/PD integration established ratios of average concentration over 48 h (Cav0–48 h)/MIC of 5.87 and 0.27 μg/mL (P. multocida) and 0.70 and 0.85 μg/mL (A. pleuropneumoniae) for broth and serum MICs, respectively. PK/PD modelling of in vitro time–kill curves established broth and serum breakpoint values for area under curve (AUC0–24 h)/MIC for three levels of inhibition of growth, bacteriostasis and 3 and 4 log10 reductions in bacterial count. Doses were then predicted for each pathogen, based on Monte Carlo simulations, for: (i) bacteriostatic and bactericidal levels of kill; (ii) 50% and 90% target attainment rates (TAR); and (iii) single dosing and daily dosing at steady‐state. For 90% TAR, predicted daily doses at steady‐state for bactericidal actions were 1123 mg/kg (P. multocida) and 43 mg/kg (A. pleuropneumoniae) based on serum MICs. Lower TARs were predicted from broth MIC data; corresponding dose estimates were 95 mg/kg (P. multocida) and 34 mg/kg (A. pleuropneumoniae).

Abstract
A rat model was used to determine the bioavailability of iron and zinc in bean seeds and rice grain from enriched genotypes of these globally important staple foods. Seed and grain from the genotypes tested (intrinsically radiolabelled with either 59Fe or 65Zn) were cooked, homogenized in water, and lyophilized to dryness. The dried, radiolabelled powder was fed to young male rats in single meals. Bioavailability was calculated from the amount of radiolabelled iron and zinc retained in the rats over a 10-day period as determined each day by whole-body gamma spectrometry assay. The data collected demonstrate that increasing the amount of iron or zinc in enriched rice grain and bean seed significantly increases the amount of iron or zinc bioavailable to rats. Although a rat model is not ideal for determining iron and zinc bioavailability to humans, because rats are much more efficient at absorbing iron and zinc from plant foods than humans, rats can be used to give relative estimates of bioavailable iron and zinc in plant foods. These estimates can be used to rank promising genotypes of staple foods for use in later feeding trials with humans, greatly reducing the numbers of genotypes that would have to be tested in humans without use of the rat model. Ultimately, because of the complexities of determining the bioavailability to humans of iron and zinc in plant foods, human feeding trials performed under free-living conditions should be conducted with the most promising genotypes before these genotypes are released for distribution to breeding programmes worldwide

Abstract
Iron and zinc deficiencies are common in populations dependent on cereal-based diets because of the poor bioavailability of these minerals in those foods. Selective breeding of high-mineral grains can improve the total intake of iron and zinc. However, the additional iron and zinc from those grains may not be available for absorption because of the high phytate content of cereals. Iron and zinc bioavailability needs to be measured before the high-mineral crops are promoted. Iron or zinc bioavailability can be measured from the response of a physiological variable, assessment of body retention, tissue or blood uptake, changes in pool size, or rates of absorption. Iron bioavailability is preferentially measured from erythrocyte uptake of oral radioactive or stable iron tracers; zinc bioavailability is measured from the rate of absorption of an oral isotopic tracer compared with an intravenous tracer. The oral label, which is required for studies of both iron and zinc, may be intrinsically added to the plant during growth or extrinsically added before feeding. Iron and zinc bioavailability from intrinsically and extrinsically labelled normal and high-mineral common bean varieties was tested in young women with low iron stores. The absorption of intrinsic and extrinsic labels of iron and zinc did not differ. The bioavailability of iron and zinc from both varieties was low, about 1.5% and 13%, respectively. Methods to improve the bioavailability of iron and zinc from plant foods need to be developed.

Abstract
The aim of this study was to investigate the association between four single nucleotide polymorphisms in NR3C1 (Tth111I, BclI, ER22/23EK, and N363S), which encode the glucocorticoid receptor, and asthma susceptibility in patients from the Henan Province of China. Three hundred and twenty-eight patients with asthma and 60 healthy volunteers were recruited to this study. The target SNPs were genotyped by polymerase chain reaction (PCR)-high resolution melting and PCR-restriction fragment length polymorphism. The frequencies of the AA (8.84%) and GG (30.79%) genotypes of Tth111I were higher, and that of the AG genotype was lower (60.37%), in the asthma patients compared to that seen in healthy controls (5.00, 26.67, and 68.33%, respectively). On the other hand, asthma patients showed higher frequencies of the AA genotype (78.05%) of N363S, and lower frequencies of the AG and GG genotypes (15.55 and 6.40%), compared to healthy volunteers (71.67, 18.33, and 10.00%, respectively). Neither of these differences were found to be statistically significant. Moreover, we observed no significant differences in the genotype or allele frequencies of the BclI and ER22/23EK SNPs between the patient and control groups. In conclusion, SNPs in NR3C1 were not significantly associated with asthma in patients from the Henan Province. Patients showed higher frequencies of the AA and GG genotypes of Tth111I and the AA genotype of the N363S SNP compared to healthy volunteers, although these differences were not significant.

Abstract
OBJECTIVE Uterine artery occlusion is often used to treat symptomatic uterine myomas, as this is a minimally invasive approach. However, alternative methods for uterus-sparing therapy are in development. This study aimed to compare the clinical effects of laparoscopic uterine artery occlusion (LUAO) in combination with laparoscopic myomectomy (LM) with LM alone for the management of symptomatic uterine leiomyomas. STUDY DESIGN This multicentre study was a retrospective controlled investigation. In total, 618 patients with symptomatic uterine myomas from six hospitals in Eastern China underwent LUAO+LM or LM alone between June 2011 and December 2012. Operative time, blood loss, transfusion, highest temperature, postoperative hospital stay, complications and follow-up results were compared between the two groups. RESULTS Complete clinical data were available for 504 patients. Among these, 324 patients underwent LUAO+LM and 180 patients underwent LM alone. Mean±standard deviation blood loss, transfusion, highest peri-operative temperature and duration of hospital stay were significantly lower in the LUAO+LM group compared with the LM group (83.61±53.70ml vs 109±58.43ml, 1.85% vs 6.11%, 37.6±0.40°C vs 37.9±0.45°C and 5.11±0.62 days vs 6.10±0.83 days, respectively). The mean duration of follow-up was 38.97±5.82 months in the LUAO+LM group and 37.30±2.25 months in the LM group (p>0.05). The relief of abnormal uterine bleeding, reduction of uterine volume and recurrence of myomas were more remarkable in the LUAO+LM group than the LM group (97.22% vs 83.75%, 62.42% vs 51.83% and 3.47% vs 10.63%, respectively). CONCLUSIONS LUAO in combination with LM was associated with higher surgical quality, greater relief of abnormal symptoms and less recurrence of myomas compared with LM alone. LUAO in combination with LM is recommended for women with symptomatic uterine myomas who wish to preserve their uterus.

Abstract
Depression is a common neuropsychiatric disorder which has been associated with a wide range of structural and functional changes within specific brain regions. Ginsenoside Rg1 has been shown to exert a number of neuroprotective effects as demonstrated in various in vivo and in vitro studies. However, little information is available regarding the site and mechanisms of ginsenoside Rg1 in promoting antidepressant effects. The present study aimed to investigate the neuroprotective and ameliorating effects of ginsenoside Rg1 on depression-like behavior as induced by chronic unpredictable mild stress (CUMS). The results showed that CUMS was effective in producing depression-like behaviors in rats as indicated by decreased responses in sucrose preference and forced swim tests which were associated with ultrastructural changes in neurons within the amygdala. Moreover, levels of PKA and CREB phosphorylation and the expression of brain-derived neurotrophic factor (BDNF) were decreased in the amygdala of CUMS rats. Remarkably, chronic ginsenoside Rg1 (40 mg/kg, i.p., 5 weeks) treatment significantly ameliorated these behavioral and biochemical alterations associated with CUMS-induced depression. Taken together, the results of the present study demonstrate that ginsenoside Rg1 exhibits antidepressant-like effects against CUMS-induced depression. This amelioration of depression-like behaviors by ginsenoside Rg1 appears to be mediated, at least in part, by a CREB-regulated increase of BDNF expression in the amygdala of rats. Therefore, these findings reveal the therapeutic potential of ginsenoside Rg1 for use in clinical trials in the treatment of depression.
