Objective:To explore the effect of inherent depression on chronic visceral hypersensitivity. The differences of visceral sensitivity, colitis, and brain activation between Fawn-Hooded ( FH/Wjd) and Sprague-Dawley( SD) rats were identified after neonatal colon acetate stimulation.Methods:The specific pathogen free Fawn-Hooded (FH/Wjd) and Sprague-Dawley(SD) rats were used to establish irritable bowel syndrome (IBS) model.The visceral sensitivity was measured by colorectal distension (CRD). The expression of 5-hydroxytryptamine (5-HT), mast cell (MC), indoleamine 2,3-dioxygenase (IDO) in colon and IDO in specific cerebral regions were detected through immunohistochemistry.Results:Ab-dominal withdrawal reflex ( AWR) scores showed that visceral sensitivity of acetate-enema groups was sig-nificantly higher than that of saline-enema groups ( FH/Wjd:2.44 ±0.04 vs.1.96 ±0.07, P<0.05;SD:1.75 ±0.13 vs.1.32 ±0.05, P<0.05).Furthermore, FH/Wjd rats of IBS group scored signifi-cantly higher than SD rats of IBS group (2.44 ±0.04 vs.1.75 ±0.13, P<0.05).The MC amounts of both SD and FH/Wjd IBS group rats were significantly more than those of their control groups ( FH/Wjd:43.24 ±1.72 vs.24.92 ±1.38, P <0.01.SD:23.80 ±1.28 vs.14.24 ±0.92, P <0.01).
Besides, the MC amounts of control and IBS group of FH/Wjd rats were significantly more than that of SD IBS group rats ( P<0 .01 ) .The IDO and 5-HT positive cells in colonic mucosa of IBS group of both SD and FH/Wjd rats were significantly more than those of their control groups, respectively(P <0.01). The IDO, 5-HT positive cells in colonic mucosa of both control and IBS group of FH/Wjd rats were significantly more than those of both control and IBS group of SD rats ( control:IDO,24.64 ±2.22 vs. 15.52 ±1.39;5-HT,21.32 ±1.26 vs.12.72 ±1.12.IBS: IDO,44.92 ±2.31 vs.20.85 ±1.72;5-HT, 31.84 ±1.57 vs.19.65 ±1.09.P <0.01).The expression of IDO in prelimbic cortex (PrL) areas of FH/Wjd IBS rats was significantly higher than that of IBS group of SD rats (49.60 ±4.31 vs. 35.60 ±2.42, P <0.01) , and the expression of IDO in rostral anterior cingulate cortex ( rACC) areas of FH/Wjd IBS rats was significantly more than that of FH/Wjd control rats (45.44 ±1.16 vs.34.08 ± 2.76, P <0.01) .Conclusion:Inherent depressive FH/Wjd rats were more sensitive to neonatal colon acetate stimulation, presenting as visceral hypersensitivity which maybe associated with increased MC amounts and over-expression of 5-HT and IDO in colon, suggesting that depression disorder may aggra-vate functional disturbance of gastrointestinal tract by regulating the response to inflammatory stimulation.

Meningomyelocele combined with squamous cell carcinoma is rare in literature. In this article,we report the clinical and treatment of a patient with meningomyelocele and squamous cell carcinoma and discuss its mechanism,clinical feature,therapy and prognosis.The patient was a 11-year-old Chinese boy.At the time of his birth he was noted to have a lumbosacral meningomyelocele,which was disrupted and the cerebral spinal fluid flew out when the child was six.The wound surface abrased and exudated repeatedly.Two months before admission,the meningomyelocele was disrupted again and the condition got worse.Inspection showed a meningomyelocele in the lower lumbar region 10 cm in diameter,consisting of a cauliflower-shaped swelling and a central crater containing black slough.The area smelled foul and was constantly draining serosanguineous fluid.Magnetic resonance imaging showed meningomyelocele associa-ted with spinal dysraphism and tethered cord syndrome.After thorough preparation,operation was undertaken.A perpendicular skin incision,which was carried down to the lumbar aponeurosis,allowed the main bulk of the tumour to be undercut and removed.The quick frozen pathological examination confirmed that it was squamous cell carcinoma.The skin and subcutaneous tissue were fruther resected and the vertebral canal explored until frozen section showed the excision edge was clear.Skin closure was achieved by a bi-pedicle advancement flap,some 10 cm wide and the secondary defect was closed with a thigh skin graft.Histological examination showed that the massive outgrowth was a well-differentiated squamous cell carcinoma.The postoperative recovery was uneventful and the wounds healed by primary intention.Although meningomyelocele combined with squamous cell carcinoma is rare in literature,the possibility of can-cerization should be considered when there is a long-term and non-healing ulcer (Marjolin ulcer) with foul smell in a meningomyelocele patient.

Objective To explore the feasibility of inherent depressive Fawn-Hooded (FH/Wjd)rats as a comorbidity model of mental disorder and irritable bowel syndrome (IBS) by comparing visceral sensitivity of FH/Wjd rats and Sprague-Dawley (SD) rats. Methods Depression trait of FH/Wjd rats was validated through forced swimming test (FST) and sucrose preference test (SPT).Visceral sensitivity to colorectal distention (CRD) under various pressures was assessed by abdominal withdrawal reflex (AWR). The expression of 5-HT in rats' colon,c-fos expression in colon and brain areas of infralimbic cortex (IL),prelimbic cortex (PrL) and rostral anterior cingulated cortex (rACC)was tested with immunohistochemistry. Results FST indicated that the immobility time of FH/Wjd rats was significantly longer than that in SD rats (t=-8. 931,P<0. 01). SPT showed that the ratio of sucrose water in total liquid consumed was significantly lower in FH/Wjd rats than that of SD rats(t=4. 155,P=0. 01). At each CRD pressure gradient (20,40,60 and 80 mm Hg,1 mm Hg=0. 133kPa),AWR score was all significantly higher in FH/Wjd rats than that of SD rats (t=-2. 697,-3.464,-6.822 and -3. 976,P=0. 022,0.006,0.000 and 0.003). The expression level of 5-HT in FH/Wjd rats' control group was significantly higher than that of SD rats' control group (t=-11.371,P=0. 000). Compared with their own control group,5-HT expression increased both in FH/Wjd rats dilated groups and SD rats dilated groups,and the expression level in FH/Wjd rats was higher than that of SD rats (t= -3. 364,P= 0. 007). There was no significant difference of c-fos expression in colon and prefrontal brain areas between FH/Wjd rats' control group and SD rats'control group (colon:t=-0. 129,P= 0. 900;IL:t=-1. 316,P= 0. 218;PrL:t=1. 241,P = 0. 243;rACC:t=2. 151,P = 0. 057). Compared with their own control group,the expression of c-fos in colon and prefrontal brain areas significantly increased both in FH/Wjd rats dilated groups and SD rats dilated groups,and the expression level in FH/Wjd rats was higher than that of SD rats (colon: t=- 5.864,P= 0.000;IL:t=-2. 530,P = 0. 030;PrL:t=-7. 039,P= 0. 000;rACC:t=-6. 489,P=0. 000). Conclusions Inherent depressive FH/Wjd rats present visceral hypersensitivity. Meanwhile,the expression of 5-HT in colon is high,and with hyperreactivity to visceral noxious stimuli in colon and brain IL,PrL,and rACC areas. FH/Wjd rats might be a comorbidity animal model of mental disorder and IBS.

Objective:
To investigate the clinicopathologic characteristics of intractable epilepsy.
Methods:
Based on the classification criteria proposed by the International League Against Epilepsy (ILAE), a retrospective analysis of the pathological characteristics was done in 822 patients who underwent epilepsy surgery in Sanbo Brain Hospital, Capital Medical University, from June 2008 to December 2012.
Results:
The mean age of epilepsy onset was 9.9 years, mean duration of epilepsy was 11.9 years. Complex partial seizures were the main presenting features. Histopathological study showed 33 cases (4.01%) with mild forms of cortical malformations, 690 cases (83.94%) with focal cortical dysplasia (FCD) and 99 cases with others (including 39 pure hippocampal sclerosis, 20 cystosclerosis, 19 Sturge-Weber syndrome, 8 tuberous sclerosis complex, 6 without significant pathological changes, 5 gyral malformations and 2 hamartoma). Among the 690 FCD cases, 106 were FCD typeⅠ, 91 were FCD typeⅡ and 493 were FCDⅢ(Ⅲa: 160, Ⅲb: 106, Ⅲc: 26 and Ⅲd: 201).
Conclusions
FCDⅢd is the most common histopathological subtype causing intractable epilepsy, mainly due to focal hypoxia/ischemia in the perinatal period, which results in scarring of local brain tissue; this is followed by other isolated forms of FCD (FCDⅠand FCDⅡ), and then FCD Ⅲa and FCD Ⅲb. The reason to distinguish isolated forms of FCD (types Ⅰ and Ⅱ) from FCD Ⅲ and to subclassify FCD Ⅲ is to allow better definition of cortical dyslamination. Therefore, the pathogenic factors of intractable epilepsy can be grouped in greater details, and facilitate the diagnosis and potential curative treatment of intractable epilepsy.
