Functional gastrointestinal disease is a group of clinical syndrome of non-organic disease. Its various clinical symptoms have a certain specificity and overlap phenomenon, and the mechanism is not clear. TCM believes thatphychological factorsare an important cause. Emotion failurecan effect spleen and stomach functionthrough liver and heart directly or indirectly.At present, the phychological factors and the relationship between functional gastrointestinal disease are getting attentiongradually. It is recognized that the mechanism of phychological factorsmay be related to brain axis dysfunction, mast cell activation, intestinal flora and so on. This article expounded the above-mentioned mechanism and reviewed the detailed TCM intervention measures to functional gastrointestinal disease in recent years.

Irritable bowel syndrome( IBS)is a common functional gastrointestinal disease,relevant investigations on pathogenesis of IBS mainly focus on genetic susceptibility, social psychological stress, visceral hypersensitivity, dysregulation of brain-gut axis,dysbiosis of intestinal flora,and dysimmunity of intestinal mucosa. This article reviewed the correlation between dysbiosis of intestinal microbiota and dysregulation of brain-gut axis in IBS.

Aim To investigate the effect of flavonoids from Prinsepia utilis Royle( FPR) on the histomorphol-ogy of kidney in diabetic mice, and to investigate its protective mechanism. Methods Diabetic mice in-duced by alloxan were given FPR orally each day for four weeks. After the administration for two and four weeks, ten mice in each group were randomly sacri-ficed. The kidneys were removed and weighed. The extracted renal tissue was embedded with paraffin and sectioned, the sections were stained with Hematoxylin and Eosin(HE)、Periodic acid Schiff(PAS) and Go-mori, and then observed under the microscopy. 1mm3 of renal cortex fixed with glutaral in four centi-degree , and then the ultrastructure of each group was observed under the electron microscope respectively after four weeks′ treatment. Results Compared with the model control group, in the treatment group, observation un-der the microscopy showed that glomerular volume and mesangial cells reduced, FPR could relieve thickening of the glomerular basement membrane ( GBM ) , little inflammatory cells infiltrated in the interstitium,tubular epithelial cells almost became normal, renal tubule had little glucogen, fiber decreased in the interstitium of renal tubule. Observation under the electron micro-scope indicated that foot process in podocytes lined up in order, mitochondria of the renal tubule’ s epithelial cell almost recovered. Conclusion FPR can relieve the changes of renal pathology,improve renal function, and delay the progression of pathologic changes of kid-ney in diabetic mice partly through reducing the blood glucose and the blood lipid.

Objective To investigate the dynamic changes and its significance of inflammatory factors in cervical secretions and prior cervical tissues after cervical conical resection.Methods Women who received prior cervical conization during December 2013 and December 2015 in this hospital were selected,then the cervical tissue and secretion were collected regular interval after the conization.The expression of tumor necrosis factor-α(TNF),interleukin 6 (IL-6) and high mobility group protein 1 (HMGB1) were quantitative detected and analyzed.The expression and infiltration of inflammatory cell were detected by HE and immunohistochemical staining.Results The expression of TNF-α,IL-6 and HMGB1 in cervical tissues and secretions increased gradually after priorcervical conization,which reached the peak at 1 to 2 weeks after priorcervical conization,and then gradually decreased,the differences were statistically significant when compared with the preoperative control group (P＜0.05).The inflammatory cell infiltration and the inflammatory response were most severe at 1st week after the conization.The expression of TNF-α,IL 6 and HMGB1 was at 1st week after the conization were significantly higher than that of the 4thweek group.Conclusion The cervical inflammatory were most severe after the prior cervical conization about 1-2weeks,and the hysterectomy should be avoided at this stage.

Objectives To investigate the clinical significance of dual energy spectral CT (DESCT) in quantitatively differentiating peripheral lung cancers from pulmonary inflammatory masses.Methods Sixty patients with 35 lung cancers and 25 inflammatory masses underwent DESCT to get arterial phase (AP) images and venous phase (VP) images.Iodine concentrations in the central and peripheral zone of the masses were measured and normalized to the aorta as normalised iodine concentration (NIC).The difference of NIC between central and peripheral zone of the masses (dNIC) was calculated.The spectral attenuation curve was obtained automatically and the slope of curve (λHU) was also calculated in the two groups.The quantitative parameters was presented as M (Q1,Q3),and Wilcoxon signed rank test was used to compare above two independent samples.Receiver operating characteristic (ROC) curves were generated to calculate the sensitivity and specificity.Results NICs in the central zone of peripheral lung cancers were significantly lower than that of inflammatory masses:mean NICs were 0.03 (0,0.05) versus 0.12 (0.07,0.20) in AP,and 0.14 (0.12,0.19) versus 0.30 (0.21,0.57) in VP (Z=-4.14,-3.70,respectively,P＜0.01).While the dNIC values of lung cancers were significantly higher than that of inflammatory masses:dNIC values were 0.08 (0.05,0.11) versus 0.04 (-0.02,0.08) in AP,and 0.23 (0.17,0.34)versus 0.07 (-0.04,0.08) in VP(Z=-2.56,-4.00,respectively,P＜0.05).Mean λHU values of lung cancers were also lower than inflammatory masses:1.03 (0.67,1.67)versus 2.75 (1.61,3.19) in AP,and 1.58 (1.30,2.17) versus 3.25 (2.37,4.54) in VP (Z=-3.90,-4.42 respectively,P＜0.01).According to ROC curves,cutoff value of λHU =2.11 in VP had the highest sensitivity (89％) and specificity (91％) in differentiating peripheral lung cancers from inflammatory masses.Conclusions Contrast-enhanced dual energy spectral CT imaging with some quantitative parameters such as normalised iodine concentration,dNIC,and the slope of spectral attenuation curves may be a promising new method for differentiating peripheral lung cancers from inflammatory masses.

Objective To assess the diagnostic value of CT spectral imaging using quantitative iodine-based material decomposition images in the evaluation of pulmonary embolism. Methods Fifty-three patients underwent CT angiography with spectral imaging mode on a GE Discovery CT750HD scanner. Iodine distribution in the lung parenchyma using the iodine-based material decomposition images was quantitatively measured by post-processing. Monochromatic CT angiographic images were reconstructed from the same data sets and thee images were reviewed for the identification and localization of pulmonary embolism as well as the degree ( partial or complete) of the embolic occlusion. The number and location of perfusion defects were recorded. The iodine content of perfusion defects and normal lung parenchyma on the iodine maps were measured by one reader using an ROI analysis. Comparative analyses were obtained using the Chi-square test for categorical data. Two independent samples rank test and 2 related samples signed-rank test were used to compare iodine densities between different groups. Results CT angiography showed no pulmonary embolism in 33 patients, and iodine distribution was homogeneous. A total of 93 clots with lobar ( n = 26), segmental (n = 54) and sub-segmental (n=13) distribution were detected in 19 patients; Fifty-one clots were occlusive and 42 clots were non-occlusive. The iodine-based material decomposition images of all occlusive clots showed lobar, segmental or sub-segmental iodine distribution defects; whereas eleven of 42 non-occlusive clots had evidence of iodine distribution defects. There was significant difference ( x2 = 39. 94,P＜0. 01 ) in the perfusion defects between occlusive and non-occlusive clots. There was a significant difference in iodine content between normal lung parenchyma [ (1.92 ±0. 54) g/L] and perfusion defects [ (0. 30 ± 0. 20)g/L] (Z= -5.63, P ＜ 0. 01 ). There was a significant difference in the iodine content of peffusion defects before [ (0. 26 ± 0. 23 )g/L] and after anticoagulation [ (0. 94 ± 0. 50 )g/L ] ( Z = -3.93,P ＜ 0. 01 ). Conclusion With the ability of iodine mapping, CT spectral imaging is areliable method in the evaluation of pulmonary embolism both qualitatively and quantitatively, and may be a useful tool in providing information regarding the severity of PE and monitoring therapeutic efficacy.
