Abstract
AIMS The short-term effects of different organic manure nitrogen (N) input on soil ammonia-oxidizing archaea (AOA) and bacterial (AOB) activity and community structure at maturity stages of early rice and late rice were investigated in the present paper, in a double-cropping rice system in southern China. METHODS AND RESULTS A field experiment was done by applying five different organic and inorganic N input treatments: (i) 100% N of chemical fertilizer (M0), (ii) 30% N of organic manure and 70% N of chemical fertilizer (M30), (iii) 50% N of organic manure and 50% N of chemical fertilizer (M50), (iv) 100% N of organic manure (M100) and (v) without N fertilizer input as control (CK). Microbial community changes were assessed using fatty acid methyl esters, and ammonia oxidizer (AO) changes were followed using quantitative PCR. The results showed that AOA were higher than that of AOB based upon amoA gene copy at maturity stages of early rice and late rice. Also, the abundance of AOB and AOA with M30, M50 and M100 treatments was significantly higher than that of CK treatment. Manure N input treatments had significant effect on AOB and AOA abundance, and a higher correlation between AOB and manure N input was observed. AOB correlated moderately with soil organic carbon content, and AOA correlated moderately with water-filled pore space. CONCLUSIONS This study found that abundance of AOB and AOA was increased under the given organic N conditions, and the soil AOB and AOA community and diversity were changed by different short-term organic manure N input treatments. SIGNIFICANCE AND IMPACT OF THE STUDY Soil microbial community and specific N-utilizing microbial groups were affected by organic manure N input practices.

Abstract
BACKGROUND Postoperative hypocalcaemia due to dysfunction of the parathyroid glands is the most common complication after total thyroidectomy plus central neck dissection (CND). There is a lack of surgical techniques described to help preserve the inferior parathyroid gland in situ during CND. The objective of this study was to introduce the 'TBP layer' (layer of thymus-blood vessel-inferior parathyroid gland) concept for preserving the inferior parathyroid gland in situ during CND, and to evaluate its effectiveness. METHODS The study group included patients with primary papillary thyroid cancer who underwent total thyroidectomy with CND using the new surgical concept between January and December 2014. The control group included sex- and age-matched patients who underwent conventional total thyroidectomy with CND between January 2012 and December 2013. The proportion of inferior parathyroid glands preserved in situ and postoperative hypoparathyroidism rates in the two groups were compared. RESULTS There were 181 patients in the study group and 306 in the control group. There were no significant differences between the groups in tumour size, multifocality, extrathyroidal extension, and number of harvested and metastatic central lymph nodes. The rate of inferior parathyroid gland preservation in situ was significantly improved from 37·9 to 76·3 per cent on the left side (P < 0·001), and from 52·0 to 77·9 per cent on the right side (P < 0·001), in the study group compared with the control group. The incidence of transient hypoparathyroidism decreased significantly from 35·0 to 7·2 per cent (P < 0·001). CONCLUSION Applying the proposed surgical concept improved the rate of inferior parathyroid gland preservation in situ and decreased the incidence of transient postoperative hypoparathyroidism.

Abstract
The clinical significance of serum S-100β levels in neonates with hypoxic-ischemic encephalopathy (HIE), as a reference index to assess HIE severity, was evaluated in this study. On the basis of our strict inclusion and exclusion criteria, relevant high-quality case-control studies reporting the association between HIE and S-100β protein were selected from electronic database searches. The STATA version 12.0 software was used for the statistical analyses. The database search initially retrieved 93 studies (37 in English and 56 in Chinese), and following a multistep screening process, 13 high-quality studies were eventually included in our meta-analysis. The 13 case-control studies included a total of 646 HIE neonates and 381 healthy controls. The results of this meta-analysis revealed that serum S-100β levels in mild, moderate, and severe HIE neonates were significantly higher than those in healthy controls, and the differences were statistically significant. Importantly, the serum S-100β levels increased incrementally with HIE severity. Our results support the hypothesis that S-100β is an important biological indicator of HIE and serum S-100β levels can be used as a reference index to assess HIE severity.

Abstract
The present study investigates the effects of electroacupuncture (EA) on urinary bladder pressure (UBP) in patients with acute gastrointestinal injury (AGI). Twenty patients with AGI admitted to the First Hospital of Jiaxing intensive care unit from December 2011 to June 2013 were evaluated. Conventional group patients (n = 10) were administered moderate enteral nutritional support, and electroacupuncture group patients (n = 10) were administered enteral nutritional support followed by EA at bilateral Zusanli (ST-36), Shangjuxu (ST-37), Hegu (LI-4), and QuChi (LI-11) acupoints. UBP was then measured every 6 h and the serum creatinine once daily for 7 days. There were no statistically significant patient demographic differences in the study groups (P > 0.05). The initial UBP of both patient groups was ≥12 mmHg. On days 6 and 7, the UBP significantly decreased in the EA group compared to the conventional group (P < 0.05). The serum creatinine concentration on day 7 was significantly lower in the EA group than in the conventional group (P < 0.05). Based on these results, electroacupuncture contributed to gastrointestinal motility recovery in patients with AGI. This procedure may reduce UBP and provide organ-protective effects in AGI patients.

Abstract
To investigate the influence of histone deacetylases on nuclear reprogramming after nuclear transfer, we treated the cloned embryos with a histone deacetylase inhibitor, Trichostatin A (TSA). In the present study, global changes in acetylation of histone H3-lysine 14, histone H4-lysine 12, and histone H4-lysine 5 were studied in rabbit in vivo fertilized embryos, somatic cell nuclear transfer (SCNT) embryos, and TSA-treated SCNT embryos. From the pronuclear to the morula stage, the deacetylation-reacetylation changes in acetylation of histone H3-lysine 14 and histone H4-lysine 12 occurred in both fertilized embryos and TSA-treated cloned embryos; however, the distribution pattern in untreated cloned embryos failed to display such changes. More interesting, the signal of acetylation of histone H4-lysine 12 in cloned embryos was detected in both the inner cell mass and the trophectoderm, whereas TSA-treated cloned embryos showed the same staining pattern as fertilized embryos and the staining was limited to the inner cell mass. The histone acetylation pattern of TSA-treated SCNT embryos appeared to be more similar to that of normal embryos, indicating that TSA could improve nuclear reprogramming after nuclear transfer.

Abstract
To investigate the role of basal ganglia in locomotion, a multiple-channel, single-unit recording technique was used to record neural activity simultaneously in the dorsal lateral striatum (STR), globus pallidus (GP), subthalamic nucleus (STN) and substantia nigra pars reticulata (SNr) during spontaneous and treadmill locomotion tasks in freely moving rats. Active and quiescent phases appeared alternately in a spontaneous movement session that lasted 60 min. Principal component analysis of the ensemble neural activity from each region revealed a close correlation with spontaneous motor activity. Most of the neurons in these four basal ganglia areas increased their firing rates during the active phase. In the treadmill locomotion task, the firing rates of neurons in all recording areas, especially in the STN, increased significantly during locomotion. In addition, neural responses related to tone cue, initiation and termination of treadmill were observed in a subset of neurons in each basal ganglia region. Detailed video analysis revealed a limb movement related neural firing, predominantly in the STR and the GP, during treadmill walking. However, the proportion of neurons exhibiting limb movement related firing was significantly greater only in the STR. A few neurons in the STR (4.8%) and the GP (3.4%) discharged in an oscillatory pattern during treadmill walking, and the oscillatory frequency was similar to the frequency of the step cycle. This study demonstrates a variety of neural responses in the major basal ganglia regions during spontaneous and forced locomotion. General activation of all major basal ganglia regions during locomotion is more likely to provide a dynamic background for cortical signal processing rather than to directly control precise movements. Implications of these findings in the model of basal ganglia organization are discussed.

Abstract
The effects of Delta-9-tetrahydrocannabinole (Delta-9-THC) on locomotor activities and related basal ganglia neural responses were investigated in rats. A multiple-channel, single unit recording method was used to record neuronal activity in the dorsal lateral striatum, the globus pallidus, the subthalamic nucleus, and the substantia nigra pars reticulata simultaneously during spontaneous movement and treadmill locomotion. Delta-9-THC treatment (0.05-2.0 mg/kg, i.p.) dose-dependently decreased spontaneous motor activity and altered walking patterns in treadmill locomotion in that stance time was increased and step number was decreased. In parallel with the behavioral effects, Delta-9-THC treatment inhibited neural activity across all four basal ganglia areas recorded during both motor tests. Further, this inhibition of basal ganglia neural activity was behavioral context-dependent. Greater inhibition was found during resting than during walking periods in the treadmill locomotion test. Delta-9-THC treatment also changed firing patterns in the striatum and globus pallidus. More neurons in these regions discharged in an oscillatory pattern during treadmill walking with Delta-9-THC, and the oscillatory frequency was similar to that of the step cycle. Synchronized firing patterns were found in few basal ganglia neurons in the control condition (approximately 1%). Synchronized firing patterns increased during the treadmill resting phase after Delta-9-THC treatment, but still represented a very small proportion of the total neural population (1.9%). The drug treatment did not change neural responses to the tone cue proceeding treadmill locomotion. This study demonstrates dose-dependent inhibitory effects of cannabinoid injection on motor activity. This effect may be related to the behavioral context-dependent inhibition observed in the basal ganglia system where CB1 receptors are densely distributed.

Abstract
The PGE2 concentration of sera and tumor tissues in human hepatocellular carcinoma (hHCC) xenografts in nude mice was examined by radio-immuno-assay (RIA) and the effect of intraperitoneal administration of exogenous of PGE2 as well as indomethacin on tumor growth was studied. The results showed that: (1) Plasma and tumor tissue PGE2 levels of hHCC-bearing nude mice were significantly increased for 1 or 2 weeks after tumor inoculation. (2) Exogenous administration of indomethacin markedly suppressed the elevation of plasma and tissue PGE2 levels and prolonged the latent period of tumor growth. (3) Exogenous PGE2 shortened the latent period of tumor growth. This study indicates that there is intimate relation between PGE2 and hHCC growth.
