Abstract
OBJECTIVE To analyze the correlation of lymph node metastasis with clinicopathological parameters and outcomes of colorectal adenocarcinoma, and to explore its clinicopathological significance. METHODS The lymph node metastasis and clinicopathological features of 133 colorectal adenocarcinoma patients whose specimens were interpreted in Department of Pathology of Beijing Tongren Hospital between February 2011 and August 2015 were retrospectively analyzed. The relationship between the lymph node metastasis and clinicopathological features as well as outcomes was also analyzed according to the follow-up data of these patients. RESULTS Among the 133 cases, 69 had lymph node metastasis, and the other 64 had no lymph node metastasis. Compared with the non-lymph node metastasis group, the lymph node metastasis group had higher prevalence of neural invasion (20.29% vs 3.13%) and vascular invasion (36.23% vs 3.13%), deeper tumor invasion (beyond the serosa: 1.45% vs 0), lower tumor differentiation (poorly differentiated: 26.09% vs 14.06%), higher mortality (11.59% vs 1.56%) and distant metastasis (17.39% vs 4.69%) (all P<0.05). In the lymph node metastasis group, intra-group comparison among patients of different lymph node N staging (N0, N1a, N1b, N2a, N2b) also showed statistically significant differences in neural invasion, vascular invasion, circumferential resection margin, maximum diameter of the tumor, depth of tumor invasion, tumor differentiation, survival, and distant metastasis (all P<0.05). There were no statistically significant differences between the patients with lymph node metastases <12 and those with lymph node metastases ≥12 in these clinicopathological parameters(all P>0.05). CONCLUSIONS Presence/absence of lymph node metastasis and lymph node stage may be correlated with neural invasion, vascular invasion, depth of tumor invasion, tumor differentiation, survival, and distant metastasis. However, no marked relationship was detected of the number of lymph node metastases (<12 or ≥12) with clinicopathological parameters and outcomes.

Abstract
INTRODUCTION Necrotizing cellulitis of dental origin is a serious disease and requires prompt and effective management to avoid adverse outcomes. The purpose of this work is to describe the diagnostic and therapeutic difficulties encountered in this condition. METHODS This was a prospective study in the thoracic surgery department of Mali Hospital from January 2011 to February 2015. We collected consecutively 19 cases of complicating cervico-facial cellulitis of dental origin. The anatomical and clinical aspects, therapeutic modalities and difficulties are described. RESULTS Dental pain and fever were the predominant symptoms followed by cervical edema. Chest CT-scan was the basis for the diagnosis in all cases. Cervicotomy with debridement was the most performed surgical procedure. Pleural drainage was performed in 6 cases. Three patients (15.8%) died. CONCLUSION Necrotizing cellulitis of dental origin is a serious disease with high morbidity and mortality. The key radiological examination is the thoracic CT-scan. Early medico-surgical management by emergency care, tailored antibiotic therapy, removal of necrotizing tissues and drainage of collections are required to deliver a good outcome.

Stimulatory effect of the secretogranin-ll derived peptide secretoneurin on food intake and locomotion in female goldfish (Carassius auratus). Peptides 2016; 78:42-50.

Abstract
Secretoneurin (SN) is a conserved peptide derived by proteolytic processing from the middle domain of the ∼600 amino acid precursor secretogranin-II (SgII). Secretoneurin is widely distributed in secretory granules of endocrine cells and neurons and has important roles in reproduction as it stimulates luteinizing hormone release from the pituitary. A potential new role of SN in goldfish feeding is the subject of this study. Firstly, we established that acute (26 h; p<0.0001) and short-term (72 h; p=0.016) fasting increased SgIIa precursor mRNA levels 1.25-fold in the telencephalon, implicating SN in the control of feeding. Secondly, we determined that intracerebroventricular injections of the type A SN (SNa; 0.2 and 1 ng/g BW) increased food intake and locomotor behavior by 60 min. Fish injected with the lower and higher doses of SNa (0.2 and 1 ng/g) respectively exhibited significant 1.77- and 2.58-fold higher food intake (p<0.0001) than the saline-injected control fish. Locomotor behavior was increased by 1.35- and 2.26-fold for 0.2 ng/g SNa (p=0.0001) and 1 ng/g SNa (p<0.0001), respectively. Injection of 1 ng/g SNa increased mRNA levels of hypothalamic neuropeptide Y 1.36-fold (p=0.038) and decreased hypothalamic cocaine-and amphetamine-regulated transcript by 33% (p=0.01) at 2h and 5h post-injection, respectively. These data suggest interactions of SNa with stimulatory and inhibitory pathways of food intake control in fish.

Abstract
It is expensive to induce experimental autoimmune myasthenia gravis (EAMG) by active immunity, and difficult to obtain natural acetylcholine receptor (AChR). We sought a new method of inducing EAMG by immunizing rats with artificially synthesized AChR. The AChR mRNA in TE671 cells was extracted and reverse transcribed. The inclusion body was purified and protein concentration was determined, and the EAMG animal model was used for induction. The serum was extracted from rat blood. The antibody titer was determined using enzyme-linked immunosorbant assay (ELISA). The concentration of decay accelerating factor (DAF) in the rat serum was determined by ELISA, and the metabolism of serum rDAF was determined by western blot. We evaluated the inhibition of rDAF by determining the 50% complement hemolysis unit in the rat serum. The extracellular domain (ECD) nucleotide sequence clone produced by polymerase chain reaction was completely consistent with that in the human gene bank; it was induced by isopropyl β-D-1-thiogalactopyranoside to express the protein after insertion into vector pET16b. Sodium dodecyl sulfate polyacrylamide gel electrophoresis demonstrated that the inclusion body protein was the exact target. The ECD protein was able to bind with mAb35 after dialysis and renaturation, which demonstrated protein activity. The soluble ECD protein was used to immunize rats and obtain the EAMG models. The inhibitory effect of the complement was unsatisfactory owing to high decay rate after rDAF injection into the EAMG models. It is easy to induce the EAMG model by obtaining the AChRTEα1 subunit ECD protein using the substitution method.
