Visceral hypersensitivity is the core pathogenesis process of functional gastrointestinal disorders( FGIDs). Numerous studies showed that psychological stress plays a key role in the development of visceral hypersensitivity. Brain center is the key part involved in psychological stress-induced visceral hypersensitivity, especially senior central sensitization. However,the specific pathophysiological mechanism remains unclear. This article reviewed studies on central role mechanism of psychological stress-induced visceral hypersensitivity.

Thioredoxin-interacting protein (TXNIP), also known as vitamin D3-up-regulated protein (VDUP1), is an endogenous inhibitor of thioredoxin (Trx), which regulates the cellular reduction-oxidation (redox) state. TXNIP regulates cellular survival, apoptosis and inflammation induced by glucotoxicity, heat shock and mechanical pressure. The above functions of TXNIP are regulated by carbohydrate response element binding protein (ChREBP) and AMP-dependent protein kinase (AMPK). In recent years, numerous studies showed that TXNIP is involved in diabetes and diabetic complications. On the one hand, TXNIP functions in diabetes by increasing insulin resistance and hepatic gluconeogenesis. TXNIP expression is induced by high glucose, which is implicated in pancreatic beta cell glucotoxicity and endothelial cells dysfunction. TXNIP may contribute to the development and progression of diabetes and its vascular complications. TXNIP may be a new target for diabetes and its vascular complications therapy.

Objective To explore the effect of Mcl-1 small interference RNA ( siRNA) on tumor necrosis factor-re-lated apoptosis-inducing ligand ( TRAIL)-induced apoptosis in gastric cancer HGC-27 cells. Methods The apop-totic rates of cells treated with TRAIL and pan-caspase inhibitor ( z-VAD-fmk) alone or combination were measured by propidium iodide (PI) method using flow cytometry. The activation of caspase-3, cleavage of PARP-1, as well as the protein level of anti-apoptotic Bcl-2 proteins Bcl-2, Bcl-XL and Mcl-1 before and after TRAIL treatment were monitored by Western blot analysis. Transfection of Mcl-1 siRNA was performed using Lipofectamine 2000 reagent. The efficiency of gene silencing was quantified by Western blot and the effect of Mcl-1 siRNA on TRAIL-induced apoptosis was measured using PI method. Results HGC-27 cells were resistant to TRAIL-induced apoptosis, and z-VAD-fmk pretreatment could block apoptosis nearly completely. Activation of caspase-3 and cleavage of PARP-1 occurred in the late stage of apoptosis. The expression levels of Bcl-2, Bcl-XL and Mcl-1 were not altered after exposure to TRAIL. Transfection with Mcl-1 siRNA could obviously downregulate the expression evel of Mcl-1 in HGC-27 cells and enhanced the sensitivity of cells to TRAIL-induced apoptosis. Conclusion Overexpression of Mcl-1 may account for the resistance of HGC-27 cells to TRAIL.ownregulationof Mcl-1 by siRNA can effectively enhance the sensitivity of HGC-27 cells to TRAIL-induced apoptosis.

BACKGROUND: A considerable number of epilepsy patients cannot be treated sufficiently by drug. Epilepsy surgery is a treatment option in these cases. However, precisely localizing epileptogenic zone in epileptic patients is a successful element of epilepsy surgery. Its goal is to remove a minimum volume to control the seizures without cognitive impairment. Presurgical evaluation typically involves electroencephalogram (EEG), video-EEG monitoring, magnetic resonance imaging (MRI), single photon emission computed tomography and neuropsychological testing. Magnetoencephalography (MEG) has been as a noninvasive technique to be used to epilepsy surgical planning and brain functional study in many countries.OBJECTIVE: To preoperatively localize epileptogenic zone in patients with lesion-associated epilepsy using magnetoencephalography, compare with noninvasive video-EEG, and assess its localizing value according to the surgical outcomes. DESIGN, TIME AND SETTING: A retrospective case analysis was performed at the Magnetoencephalography Laboratory, Guangdong 999 Brain Hospital, China between November 2001 and December 2005.PARTICIPANTS: A total of 618 epileptic patients undergoing magnetoencephalography. Spontaneous magnetic field signal was collected to analyze single dipole location. Of them, 149 patients with MRI-documented epilepsy underwent surgery. The history of disease was at least 2 years. The course of disease ranged 2-35 years, with an average of 9.5 years. METHODS: MEG was recorded by a 148-channels whole head type MEG system (Magnes WH2500, 4-D Neuroimaging, San Diego, CA, USA) in Magnetically Shielded Room (MSR, Germany). Sampling rate: 508.63 Hz, 30-minutes interictal MEG (Bandpass: 1.0-100 Hz). For magnetic source imaging, the nasion and preauricular points were applied as fiducials. Single equivalent current dipole (ECDs) and head sphere model were applied for analysis. Estimated ECDs were overlaid on T1-weighted MRI of each subject.MAIN OUTCOME MEASURES: Preoperative MEG, MRI, and video-EEG and postoperative follow-up were measured. RESULTS: The sensitivity of the interictal MEG for detecting epileptiform activity was found in 91% of the patient. In most cases, the equivalent dipoles were mainly distributed over the border and neighborhood of the structural lesions. By MEG, we were able to localize the resected region in a greater proportion of patients (62.4%, 93/149) than with noninvasive vedio-EEG (38.9%, 58/149) in all patients with MRI-documented lesions. A total of 89 patients were followed up from 3-35 months, averagely 9 months. Of the 89 patients, 72 patients (80.9%) had no postoperative seizures (EngelⅠ); 7 (7.9%) cases obtain Engel Ⅱ and Engel Ⅲ outcomes. Favorable outcomes were not seen in 10 patients (11.2%) cases (Engel Ⅳ and Engel Ⅴ). Total effective rate was 88.8% (EngelⅠ-Ⅲ). CONCLUSION: MEG is not only most useful for presurgical planning in epilepsy patients with MRI-documented lesions, but is also a noninvasive method to identify the spatial relationship between the lesion and epileptogenic zone, a precise localization of the epileptogenic zone is correlated to a favorable outcome.

Silent brain infarction (SBI) is mainly diagnosed by brain imaging which is more common in the elderly population.It is considered as the early clinical stage of symptomatic cerebral infarction and cognitive impairment.Its risk factors include age,history of smoking,hypertension,diabetes,metabolic syndrome,carotid atherosclerosis,chronic kidney disease,atrial fibrillation,and obstructive sleep apnea.The related serum biological markers include high-sensitivity C reactive protein,homocysteine,cholesterol,uric acid,and soluble intercellular adhesion molecule-1.This article reviews the advances in research on the imaging characteristics,risk factors,serum biological markers and clinical significance of SBI.

This study was aimed to investigate the effect of Rheum tanguticum on expression of serum endothelial nitric oxide synthase (eNOS), endothelin (ET) and 6-keto-prostaglandin F1α (6-Keto-PGF1α) in uric acid nephropathy rat model. After 3 weeks of treatment with different extractions of Rheum tanguticum on uric acid nephropathy rat model, levels of serum BUN, Cr and UA were measured by biochemical analyzer. ELISA method was used to measure the expression of serum eNOS, ET and 6-Keto-PGF1α. Meanwhile, pathological changes of renal tissues were observed by light microscope. The results showed that compared with the normal control group, the levels of serum BUN, Cr, UA and renal index were higher in the model group (P< 0.05). Compared with the model group, the concentration of eNOS in the model group was obviously higher in the rhubarb ethanol extraction group, rhubarb water extraction group, and allopurinol group (P< 0.05). Concentration of ET was obviously reduced in the rhubarb water extraction group and allopurinol group (P< 0.05). There was no statistical difference with the rhubarb ethanol extraction group. There was no significant difference in the concentration of 6-Keto-PGF1α among groups. Lots of inflammatory cells and uratic crystallization were observed by light microscope in renal tissues among rats in the model group. Damages of renal tissues in medication groups were alleviated than the model group. It was concluded that Rheum tanguticumcan alleviate the damage of uratic crystallization and inflammatory cell infiltration, increase the concentration of serum eNOS, and decrease the concentration of serum ET. Thus, it can reduce the damage of renal endothelial cells and protect renal functions. The effect of rhubarb ethanol extraction on reducing ET expression was less than the water extraction.

Objective To investigate the changes and significance of platelet parameters and leucocyte in the children suffered from mycoplasma pneumoniae pneumonia (MPP).Methods The platelet parameters (PLT),the platelet volume(MPV),the platelet distribution width (PDW),and the white blood cell count(WBC) were detected by automatic blood cell analyzer respectively in 300 children with MPP before and after the treatment by macrolides antibiotics for a week as well as in 40 normal children.The comparison was made among them.Results There were 156 cases that suffered from thrombocytosis (PLT ＞ 300 × 109/L) in MPP group,the incidence rate was 52.0％(156/300).While there was 1 case with thrombocytopenia,the incidence rate was 0.3％ (1/300).The WBC,MPV and PDW in MPP group before and after one-week treatment were higher than the control group.And the PLT was higher than the initial stage of hospitalization and the control group.The differences had statistical significance.Conclusion The incidence rate of thrombocytosis was high in the children suffered from MPP.The dynamic observation of platelet parameters and WBC in children with MPP could be used as the elementary basis of judging MP infection.

Objective To investigate the changes of the anion gap(AG)in the premature suffered from hyperbilirubinemia,to provide the basis for treatment.Methods The serum electrolyte,the renal function and the liver function in 94 premature babies suffered from hyperbilirubinemia were tested,and then calculated the value of AG,while the arterial blood gas analyses were done in 36 cases.Results 44 cases had high AG(46.81％),44 cases had normal AG(46.81％)and 6 cases had low AG(6.38％).The increase of AG was directly proportional to the concentration of Na+in blood,while was inversely proportion to the concentration of HCO3-.There was no close relationship between the AG and BUN,Scr in the serum.Conclusion The incidence rate of metabolic acidosis poisoning was high in premature suffered from hyperbilirubinemia with high AG,so the routine test of blood electrolyte,renal function and arterial blood gas should be done.Calculate the value of AG to guide the treatment,and to avoid correcting the acid by the alkali blindly.
