Objective To investigate the role of synaptic plasticity on the formation of visceral hypersensitivity induced by transient intestinal infection in rats. Methods Thirty male Sprague-Dawley rats were divided into normal control, acute infection and chronic infection groups with 10 each. The area under curve (AUC) of electromyography (EMG) in 10 s was used to evaluate the visceral sensitivity induced by different eolorectal distention (20,40,60 and 80 mmHg). Histological change of the colon was evaluated by H-E staining. Synaptic uhrastrueture such as synaptic cleft and synaptic vesicles was observed using transmission electron mieroseope. The mRNA and protein expressions of synaptophysin and postsynaptic density protein-95 (PSD-95) were examined by RT-PCR and Western blot, respectively. significantly higher than those of normal controls(P=0. 012, 0. 005, respectively ). In contrast, AUC of acute infection were significantly lower than those of normal controls ( P = 0. 018,0. 012, respectively ). Under the distention of 20 and 80 mmHg, no significant difference was observed among three groups (P= rats compared to normal controls(23.45±4.10 vs. 9.10±2.42, P=0. 027),but there was no statistical difference between chronic infection rats and normal controls (13. 95±7.96 vs. 9.15±2.42, P=0.78). increased. In acute infection rats, mitochondria cristae disappeared, synaptic vesicles and the length of controls, mRNA and protein of synaptophysin in ileocecum, proximal colon and distal colon were significantly increased in chronic infection rats (P＜0. 05 ), but decreased in acute infection rats with no significant difference. Compared with controls, no significant downregulation was noted in the expression protein expressions of PSD-95 were both increased in chronic infection rats (P＜0.05), and decreased in acute infection rats (P＜0.05). Conclusion Synaptic plasticity plays an important role in the formation of visceral hypersensitivity induced by transient intestinal infection in rats.

Objective Rheumatoid arthritis (RA) is a typical type Ⅲ hypersensitivity with a large number of immune complexes (IC) and complement deposits in the synovial tissue , but its specific pathogenesis is not yet clear.This article was to explore the expression of the antigenic profile of serum ICs in RA.Methods ICs were isolated from the serum of 55 patients with RA (41 cases of anti-CCP antibody [+] and 14 cases of anti-CCP antibody [-]), 41 with systemic lupus erythematosus (SLE), and another 41 healthy controls by polyethylene glycol (PEG) precipitation, separated by immunoprecipitation, digested with trypsin in gel, and then subjected to mass spectrometry for identification.The levels of total proteins were compared among different groups using Vennny 2.1.0.The protein expression was considered to be up-regulated when the total protein level of the RA group was >2 times and down-regulated when it was <0.5 times that of the control.Further functional analysis was performed on the differential proteins in RA using the STRING software.Results Totally, 277 proteins were identified in the serum ICs of the RA patients, including 162 in the anti-CCP (+) and 248 in the anti-CCP (-) RA group.Compared with the SLE and healthy control groups, only 129 proteins were found in the RA patients, including 38 in the anti-CCP (+), 109 in the anti-CCP (-) RA group, and 18 in both the two groups.Among the proteins identified in the RA patients and healthy controls, 2 and 11 were up-regulated while 17 and 21 down-regulated in the anti-CCP (+) and anti-CCP (-) RA group, respectively.Conclusion More differentially expressed proteins were identified in the anti-CCP (-) than in the anti-CCP (+) RA patients.The identification of differentially expressed proteins provides a new idea and direction for the investigation of the pathogenesis and new biomarkers of RA.

This study was aimed to observe the safety and effectiveness ofShugan Jieyu Capsules in the treatment of vasovagal syncope (VVS) with mild-to-moderate depression and anxiety, and to compare the effect with Flupentixol and Melitracen Tablets. A total of 89 VVS cases with mild-to-moderate depression and anxiety were randomly divided into 3 groups, which were group A (Shugan Jieyu Capsules group), group B (Flupentixol and Melitracen Tablets) and group C (control group). Based on the conventional therapy of VVS treatment, treatments were given to all three groups for 8 weeks. And the negative conversion ratio of VVS in each group was observed. Hamilton Depression Scale (HAMD 24 items) and Hamilton Anxiety Scale (HAMA) were evaluated for the calculation of reductive rate. Treatment emergent symptoms scale (TESS) was used in the evaluation of adverse reactions of both medications during the treatment. In the 12-month follow-up after treatment, the recurrence rate of syncope was observed in each group. The results showed that compared with pretreatment, HAMD-24 and HAMA scores of group A and group B after treatment were significantly reduced (P < 0.05). Compared with group C, the heat-up tilt testing-negative rate, HAMD-24 and HAMA reductive rate of group A and group B after treatment were significantly increased (P < 0.05). Compared with group B, the negative rate, HAMD-24 and HAMA reductive rate of group A were more significant (P < 0.05). After treatment, scores for TESS of group A was significantly lower than group B (P< 0.05). In the 24-month follow-up, the recurrence rate of syncope of group A and group B was significantly lower than group C (P < 0.05); and group A was obviously better than group B (P < 0.05). It was concluded thatShugan Jieyu Capsules can be used in the treatment of VVS with mild-to-moderate depression and anxiety. Its effectiveness and safety may be better than Flupentixol and Melitracen Tablets.

This study was aimed to investigate the effect ofDanlou pills on prevent atherosclerosis from hypercholesterolemia rabbit and its relationship with inflammatory factors as well as PI3K/AKT signal pathways. A total of 24 Japanese male white rabbits were randomly divided into the control group (CL), model group (M) and Danlou group (DL), with 8 in each group. Normal diet was given to CL rabbits. High-fat diet was given to rabbits in other groups to establish the atherosclerosis model. Danlou pills (0.5 g·kg-1·d-1) were also given to DL rabbits. Rabbits were sacrificed after 9-week medication. The contents of blood lipid, TNF-α and IL-6 were detected. HE staining was used in the observation of histological changes in the aorta. Western blot was used to observe PI3K and p-AKT expression in the aorta. The results showed that compared with CL, the contents of TG, TC, LDL, IL-6 and TNF-α were significantly increased in M (P < 0.01); PI3K and p-AKT expression in the aorta were significantly decreased (P < 0.01). Compared with M, blood lipid, IL-6 and TNF-α were significantly reduced in DL (P < 0.05, orP < 0.01); PI3K and p-AKT expression were significantly increased (P < 0.01). It was concluded thatDanlou pills had prevention effects on atherosclerosis through reducing blood lipid and inflammatory factors. The action mechanism maybe related to the activation of PI3K/AKT signal pathways.

[Objective] To investigate combined application of multiplex reverse transcription-polymerase chain reaction(mRT-PCR)and karyotype analysis detect of clonal chromosomal aberrations in acute lymphoblasfic leukemia (ALL),and explore the expression of common fusion genes.Methods 189 ALL patients were examined by multiplex RT-PCR and R or G banding techniques.[Results]10 fusion genes were detected in 69 out of 189 ALL patients(36.5％),including E2A/PBX1,TEL/AML1,BCR/ABL,MLL/AF4,MLL/AF6、MLL/AF9,MLL/AF10,MLL/ELL,SIL/TAL1,TLS/ERG.R or G banding techniques could find chromosome structural and numeracy abnormalities in 86 out of 152 patients (56.6％) available for analysis.Combination of mRT-PCR and R or G banding could raise the rate of detecting clonal chromosomal abnormalities to 69.3％.Fusion genes were detected in 33 out of 90 (36.7％) patients with adult ALL and 36out of 99 (36.4 ％) patients with children ALL,there were 22 patients with positive BCR/ABL but no TEL/AML1 in adult ALL group,while there were 24 patients with positive TEL/AML.1 and 2 with positive BCR/ABL in children ALL group.There was significant statistical difference for the expression of RCR/ABL and TEL/AML1 between adult ALL and children ALL (P＜0.01),but no difference for MLL related fusion gene,E2A/PBX1,SIL/TAL1 and TLS/ERG(P＞0.05).BCR/ABL and TEL/AML1 fusion gene could be detected in 66 ALL patients with normal karyotype (36.3％).[Conclusion]There were different biological characteristics between adults and children with ALL.mRT-PCR technique can quickly screen chromosome structural aberrations in patients with newly diagnosed leukemia.It is useful in detection of fusion genes in ALL with normal karyotypes and it would refine the karyotype analysis and provide imrootramt prognosis-relevant information.
