Inflammatory bowel disease (IBD) is a chronic nonspecific inflammatory gastrointestinal tract disease. Sarcopenia is one of the most easily overlooked complications of inflammatory bowel disease, which can lead to decline of therapeutic efficacy and poor prognosis of patients. Therefore, the inclusion of assessment and prevention of sarcopenia in the treatment of inflammatory bowel disease is of great importance in clinical practice. This article reviewed the presence of sarcopenia in inflammatory bowel disease.

Nonalcoholic fatty liver disease (NAFLD) is a clinical syndrome characterized by hepatic steatosis and fat deposition in hepatocytes in the absence of significant alcohol use. A growing number of studies have shown significant dysregulation of intestinal microbiota in patients with chronic liver disease and cirrhosis. Small intestinal bacterial overgrowth (SIBO) is a clinical syndrome induced by excessive bacteria in small intestine. This article reviewed the correlation between SIBO and NAFLD, as well as the effect of probiotics on treatment of NAFLD.

Objective To investigate and evaluate the changes of T lymphocytes and red cell immunity of peripheral blood in patients with primary hepatocyte carcinoma (PHCC) after radiofrequency ablation(RFA) treatment. Methods The pre- and post- RFA(3d,7d,14d) peripheral blood T lymphocyte subsets(T3,T4,T8,T4/T8) and red cell immunity (RBC C3 receptor flower and RBC-immuocomplex formation rate) were investigated in 120 patients with PHCC treated by RFA. Results On 7d, 14d after RFA, T3, T4 lymphocytes and T4/T8 were higher than those on preoperative day significantly(P

Objective To observe the cortical functioning of healthy volunteers during acupuncture as a way of exploring acupuncture's neural mechanisms.Methods Twenty healthy volunteers received acupuncture applied to the left hegu and waiguan acupoints while their cortical activity was examined using blood oxygenation level-dependent functional magnetic resonance imaging (BOLD-fMRI).Brain activation,especially of the regions related to motor function,were observed and analyzed.Results Acupuncture applied to the left hegu and waiguan acupoints was observed to significantly activate the left middle frontal gyrus and the inferior frontal gyrus,with many activated regions in the left insula and a few in the left cerebellum,the left precentral gyrus,the left postcentral gyrus,the left inferior parietal lobule,the left medial frontal gyrus,the left precuneus,the left anterior cingulate gyrus and the left claustrum.The right side of the brain was excited mainly in the right middle frontal gyrus and the right medial frontal gyrus.The right inferior parietal lobule and the right precentral gyrus were also activated to some extent.There was slight activation of the right middle temporal gyrus,the right superior temporal gyrus,the right insula,the right inferior frontal gyrus and the right postcentral gyrus.The negatively activated regions were mainly located on both sides of the limbic lobe,including the hippocampus,the parahippocampal gyrus and the cingulate gyrus.The left superior temporal gyrus,the left middle temporal gyrus and the right middle frontal gyrus also had small negative activation zones.Conclusions In brain regions associated with motor function,in addition to partial activation of the contralateral primary sensorimotor area,acupuncture at these two points clearly generates bilateral activation of secondary motor areas with some activation in the ipsilateral cerebellum.This may serve as a neuropathological basis for acupuncture treatment of motor dysfunction.BOLD-fMRI imaging displays the neural effects of acupuncture in an intuitive way.It can be a useful technique for further study of the neural effects of acupuncture on pathological conditions.

Objective To summarize MRI findings of focal cortical dysplasia (FCD), analyze MRI characteristics of various pathological subtypes of focal cortical dysplasia. Methods Forty-four patients with FCD were collected. Their MRI findings were analyzed retrospectively. According to pathologic findings, these patients were divided into FCD type Ⅰ group and FCD type Ⅱ group. The following MR signs were observed in the two types of FCD: ( 1 ) Focal thickening of the cortex. ( 2 ) Blurring of the gray matter-white matter junction. ( 3 ) Tapering of white matter signal intensity alteration toward the ventricle on FLAIR and on T2WI. (4)Focal brain hypoplasia. (5)Increased signal intensity of gray matter on FLAIR. (6)Increased signal intensity of gray matter on T2 WI. ( 7 ) Increased signal intensity of subcortical white matter on FLAIR.(8) Increased signal intensity of subeortical white matter on T2WI. (9) Decreased signal intensity of subcortical white matter on T1 WI. The χ2 tests and corrected χ2 tests were used for comparison between the two groups. Results In the 44 cases, there were 30 cases with FCD type Ⅰ and 14 cases with FCD type Ⅱ. FCD was identified by MRI in 32 cases. Blurring of the gray-white matter junction is the most common sign of FCD (23 cases). There were 21 cases identified by MRI in FCD type Ⅰ group. Focal brain hypoplasia is a typical sign of FCD type Ⅰ , which was found in 11 cases in FCD type Ⅰ group but none in FCD type Ⅱ group. There was statistically significant difference between the two groups (continuity corrected χ2 =5. 0286,P =0. 0249) . In FCD type Ⅱ group, 11 cases were identified by MRI. Increased cortical thickness was found in 10 eases in FCD type Ⅱ group and 11 cases in FCD type Ⅰ group ( χ2 =4. 6234 ,P =0. 0315). Increased signal intensity of subcortical white matter on FLAIR was found in 9 cases in FCD type Ⅱ group and 7 cases in FCD type Ⅰ group (χ2 =6.9180,P =0.0085). Tapering of white matter signal intensity alteration toward the ventricle was found in 4 cases in FCD type Ⅱ group and none in FCD type Ⅰ group ( continuity corrected χ2 = 6. 2883, P = 0. 0122). The above-mentioned three MRI findings showed statistically significant difference between the two groups and were features of FCD type Ⅱ.All of the other MRI findings showed no statistically significant difference between the two groups. Conclusions Different pathological subtypes of FCD have different MRI characteristics. It is helpful to make preoperative diagnosis and planning.

Objective To investigate the pattern of the cerebral white matter lesions in patients with mild and moderate Alzheimer's disease(AD)and healthy controls using proton magnetic resonance spectroscopy(~1H-MRS)and diffusion tensor imaging(DTI).Methods Twenty AD patients and Twenty healthy controls were recrnited.All subjects underwent clinical examination,neuropsychological assessment.The quantitative analysis of N-acetylaspartate(NAA),myoinositol(mI),Chotine(Cho)and Creatine(Cr)resonance signals in region of interests(ROIs)located in the paraventricular white matter region bilaterally were measured.Ratios of NAA/Cr,mI/Cr and Cho/Cr were calculated in two groups.In addition,conventional MRI and DTI scanning were received,fractional anisotropy(FA)and mean diffusivity(MD)values of white matter in the same regions were measured respectively.Results No significant difference between two groups were observed in NAA/Cr ratio(P＞0.05).A significantly increased mI/Cr and Cho/Cr were found in AD patients than in controls(P＜0.05).FA and MD values in AD patients were 0.470±0.082 and 0.771±0.099,and in controls were 0.539±0.068 and 0.691±0.064,respectively.FA value decreased significantly in AD patients(P＜0.05),M D value increased significantly in AD patients(P＜0.05).After controlling for age-related,partial correlation analysis revealed a negtive correlation between mI/Cr and FA value in the patients with AD(P＜0.05).No correlation between mI/Cr and MD was found(P＞0.05).Conclusion The results suggest that not only the gray matter is injured,but also the white matter is abnormal in AD patients.Combining ~1H-MRS with DTI alterations could provide the valuable informations about white matter lesions in AD patients.

Objective To explore the relationship of serum levels of β-amyloid precursor protein (β-APP) with degree of traumatic brain injury (TBI) and the traumatic time.Methods Sprague-Dawley (SD) rats were randomly divided into normal control and injury group.The rats in injury groups suffered from TBI after free-falling percussion with different pressure (wild-injury,moderate-injury and severe-injury group).Then serum was collected at 0.5 h,2 h,6 h,and 24 h and subject to β-APP detection by ELISA.All data were analyzed statistically with completely randomized design multiple factor repeated measure of variance analysis and least significant difference (LSD) test.Results The serum levels of β-APP were higher after injury.The serum levels of β-APP were significantly higher in moderate-injury or severe-injury group than those in normal group or slight-injury group (P＜0.05).The serum levels of β-APP were higher in severe-injury group than that in moderate-injury group with no statistical difference (P＞0.05).There was no statistical difference in serum β-APP levels between normal control and slight-injury group (P＞0.05).Conclusion The serum level of P-APP is increasingly higher with traumatic brain injury more serious and could be employed as an indicator of TBI degree.It implies that β-APP has the potential as an early diagnosis marker for TBI.
