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.

Objective To investigate the importance of PTEN protein and CD44v6 detection to the prediction of laryngeal carcinoma differentiation and cervical lymph node metastasis. Methods The expressions of PTEN protein and CD44v6 were detected by immunohistochemical SP method in 97 specimens with laryngeal carcinoma and 97 specimens with a distance over 2.5 centimeters from laryngeal carcinoma. The relations between them and their clinical significance to the laryngeal squamous cell carcinoma above Glottis by the statistical analyses tools were revealed. Results The positive expression rates of PTEN protein were respectively 55.67 %, 100 % in laryngeal carcinoma and adjacent carcinoma tissue. There was a significant difference between them statistically (P<0.01). The positive expression rates of PTEN protein are notable difference among the high, middle and low differentiation of laryngeal carcinoma, but not between the positive metastasis of lymph node of neck and the negative one(P >0.05). For the expression of CD44v6, there were notable statistical difference not only among the different differentiation of laryngeal careinoma, but also between the positive metastasis of lymph node of neck and the negative one. The low expressions of PTEN protein and the high expression of CD44v6 in the same carcinoma cell has significant negative correlation (P< 0.05). Conclusion PTEN protein may have the importance to the differentiation of laryngeal carcinoma, but no means to cervical lymph node metastasis. CD44v6 may have great importance to both.

OBJECTIVE:To investigate the safety and effects of different doses of budesonide combined with ipratropium bro-mide on rational symptom,lung function and arterial blood gas indexes of patients with acute exacerbation of chronic obstructive pulmonary diseases (AECOPD). METHODS:186 AECOPD inpatients were selected and randomly divided into low-dose,medi-um-dose and high-dose groups,with 61 cases in each group. All groups received routine treatment as ipratropium bromide 500 μg+0.9%Sodium chloride injection(NS)2 ml,oral inhalation with oxygen drive atomization nebulizer,oxygen flow rate of 4-5 L/min, 15-20 min/time,tid. Low-dose,medium-dose and high-dose group were additionally given Budesonide suspension 0.5,1.0,2.0 mg+NS 2 ml respectively,oral inhalation with oxygen drive atomization nebulizer,oxygen flow rate of 4-5 L/min 20 min/time,bid. Pa-tients in 3 groups were treated for 7 days. Pulmonary function,MRC score,arterial blood gas indexes and ADR were compared among 3 groups before treatment,3 and 7 days after treatment. RESULTS:FEV1% of 3 groups were significantly improved after treatment;3 and 7 days after treatment,FEV1% of high-dose group was higher than that of medium-dose and higher than that of low-dose group,with statistical significance(P<0.05). The MRC scales of 3 groups were significantly decreased after treatment;3 days after treatment,MRC scale of high-dose group was lower than those of medium-dose and lower than that of low-dose group,with statistical significance(P<0.05). 7 days after treatment,MRC scales of medium-dose and low-dose groups were low-er than that of low-dose group,with statistical significance (P<0.05),but there was no statistical significance in MRC scale be-tween high-dose group and medium-dose group after treatment 7 days(P>0.05). After treatment,there was statistical significance in PaCO2 and PaO2 among 3 groups (P<0.05),and the improvement of high-dose group was better than those of medium-dose and better than that of low-dose group,with statistical significance(P<0.05). No severe ADR was found in 3 groups. CONCLU-SIONS:Aerosol inhalation of 2.0 mg budesonide combined with ipratropium bromide can effectively improve pulmonary function, rational symptoms and arterial blood gas indexes with good safety.

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.

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.

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.

The time-to-event index is a kind of common evaluation index. It measures the speed of intervention effect. It is different from other index in research design, source material filling, data checking and statistical analysis. To obtain the time-to-event index, investigators can fill in the table directly and statistical analyst can compute after clinical observation. When filling in the source material or data checking, it is should be noticed that the logical relation between the time-to-event index and the visiting point and between the time-to-event index and the correlative other indicator. When statistical analyzing, it is an important issue how to deal with the cases whose time-to-event index does not appear till the observation period ends. Understanding the difference clearly can make the time-to-event index evaluate the effect of the intervention truly and make the clinical observation results reliable.

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.
