The interaction between the immune system and nervous sytem affcts nervous function.There is a close relationship between the episode of epilepsy and immunity,the molecular basis of which is the network of cytokines.In order to quest new methods of contolling epilepsy by regulating the network of cytokines,the roles of several cytokines in the ocurrence and onset of epilepsy were reviewed in this article.

Objective To analyze the clinical profiles of lupus mesenteric vasculitis (LMV).Methods Thirty-six SLE patients diagnosed with LMV and 72 SLE patients (1:2) without LMV at West China Hospital between October 2009 and January 2012 were enrolled.The imaging,clinical manifestation,laboratory examinations data were analyzed retrospectively.Quantitative differences were analyzed by the Student's t and Z tests and qualitative data were compared with Chi-square.P value less than 0.05 was considered as statistically significant.Results ① The prevalence of LMV in patients with SLE was 1.2％(36/3 051),while 47％(17/36) as the initial symptom of SLE.Thirty-six LMV patients were all female.The prevalence of abdominal pain was 78％(28/36),nausea or vomitting was 58％(21/36),abdominal distension was 50％(18/36),diarrhea was 47.2％ (17/36),intestinal perforation was 3％ (1/36) and incomplete obstruction was 8％ (3/36).Enhanced CT scan showed 81％(25/31) patients suffered from intestinal dilation and (or) mesenteric edema;SLEDAI (17±5),C3 (0.44±0.25) g/L,C4 (0.10±0.09) g/L,Z value on above items were 4.30,-3.85 and-2.94 respectively compared to SLE patients without LMV,and all P＜0.05,the differemces were significant.In addition,Also,the proportion of ANA and anti-ENA antibody showed no significant difference.68.6％(13/36) patients were also diagnosed with lupus nephritis;61％(22/36) patients were treated with methylprednisolone more than 200 mg/d resulting in relief of symptom.Conclusion Female patients with SLE may be more likely to suffer from LMV;Enhanced abdominal CT scan is still essential to the diagnosis of LMV.LMV is correlated with urinary system malfunction.LMV always occurs in active lupus with low C3 and C4 level.More than half patients should be treated with corticosteroid and cyclophosphamide pulse therapy.

Objective To evaluate the clinical outcome of stent placement in the superior vena cava (SVC) syndrome. Methods Twelve patients with stenosis of the superior vena cava and/or its main tributaries underwent placement of a self-expanding endovascular Wallstents (11 men,1 woman,mean age 51 years). Results Until death or completion of the study,the SVC syndrome was successfully controlled in 92% of the cases (11/12). There were no early procedure-related complications such as early occlusion,or migration of the stent. The recurrence rate was 16.7%. Conclusion Percutaneous venous stent placement in the superior vena cava is a relatively safe and simple procedure. In majority of cases,the symptoms of the SVC syndrome are relieved immediately and completely. Complications are rare.

Objective To investigate the effect of persistent ST-segment elevation after successful direct percutanous coronary intervention (PCI) on the late phase of left ventricular (LV) systolic function in acute anterior wall myocardial infarction.Methods Serial electrocardiograms were record before PCI and 1 hour after reperfusion in 72 patients with acute anterior wall myocardial infarction. The reduction of ST-segment elevation after successful PCI more than 50% was defined as ST-segment resolution (ST reduction group). Persistent ST-segment elevation was defined as ≥50% of peak ST elevation (ST elevation group). Echocardiography was performed on 2 to 3 weeks (early phase) and 5 to 6 months(late phase)after PCI to evaluate the LV function and ventricular wall motion abnormality (VWMA). Results Fifty-three patients (74%) had early ST segment elevation resolution and 19 patients (26%) did not. The LV function and VWMA were similar in two groups during early phase. But during the late phase, ST elevation group patients had lower LVEF and higher LVEDVI, LVESVI, VWMA index compared with ST reduction group (P

A number of studies have shown that migraine, particularly migraine with aura, has certain correlation with stroke.However, their related potential mechanism remains unclear. Migraine may be a cause and/or a risk factor for stroke. Stroke may cause the occurrence of migraine, and it may also be a disease with two clinical manifestations.

Carpal tunnel syndrome (CTS) is a common peripheral neuropathy, which include a series of symptoms results from median nerve injury. Electrical physical examination is the gold standard for diagnosis of CTS. More new technology, such as high frequency ultrasound and magnetic resonance imaging, provides more information for the diagnosis of CTS.

Objective To determine the expression levels of SOCS2 in the mouse livers under starvation, diabetes and obese conditions and to study the effect of SOCS2 on gluconeogenesis.Methods Animals were divided into 3 groups: C57BL/6J mice, the control group was fed ad libtum and the experimental group was fasted for 24 h.Diabetes model db/db and the control db/m mice were fed ad libitum.Obese model ob/ob and the control C57BL/6J mice were fed ad libitum.All the mice above were sacrificed and total RNA was isolated from mouse livers and reverse transcribed to cDNA.The expression of SOCS2 and gluconeogenesis genes in the mouse livers in the 3 groups above were detected by real-time quantitative PCR.SOCS2 was overexpressed in the primary C57BL/6J mouse hepatocytes by the adenovirus system.The effect of SOCS2 on glucose production was measured by glucose output assay.Results C57BL/6J mouse hepatic SOCS2 expression was suppressed by starvation status.The expression of SOCS2 was decreased in the livers of db/db and ob/ob mice.In contrast, the key regulators of gluconeogenesis, PGC-1α, PEPCK and G6Pase exhibited the opposite expression pattern as SOCS2 in the livers underidentical starvation, diabetes and obese conditions.The protein was Mr 23 000 and glucose production was inhibited after SOCS2 being overexpressed in the primary C57BL/6J mouse hepatocytes by adenovirus system.Conclusions SOCS2 may inhibit gluconeogenesis in the C57BL/6J mouse primary hepatocytes, and SOCS2 may be a potential target for the treatment of type Ⅱ diabetes.

Objective To investigate the expression of the genes correlated with interferon induced genes virus (MX1, OAS1, IFI44) in the peripheral blood leukocytes of patients with systemic lupus erythematosus (SLE), and to evaluate the relationships between the expression levels of these genes and diseaseactivity. Methods The clinical data of 100 SLE patients, 40 non-SLE patients with rheumatic diseases, and 40 normal controls were collected. Peripheral blood samples were collected. Total RNA was extracted and transcribed into cDNA. SYBR green dye based real-time quantitative PCR method was used to compare the expression levels (indicated as △CT value) of MX1, OAS1 and IFI44 in patients with SLE and those in the controls. Comparisons between groups were performed with ANOVA and Spearman correlations. Results ①The △CT value of MX1, OAS1 and IFI44 expression level of the SLE patients (3.4±1.8, 4.2±1.5, 8.8±2.2)was significantly higher than those of the non-SLE patients (2.4±0.4, 3.4±0.7, 5.4±2.1 ) and normal controls (2.3±1.1, 2.6±0.7, 5.2±2.0). ② The △CT value of OAS1 and IFI44 expression level of the SLE patients in severe disease was significantly higher than those of the SLE patients in mild disease and the SLE patients with stable disease. ③The ACT value of OASI and IFI44 were correlated with the SLEDAI scores (r=0.038,0.380). ④ The △CT values of MX1, OAS1 and IFI44 expression level of the SLE patients with arthritis were significantly higher than those of SLE patients without arthritis. ⑤ The △CT value of IFI44 expression level of the SLE patients with lupus nephritis (3.2±2.1,2.2±1.1) was significantly higher than that of the SLE patients without lupus nephritis. ⑥ There was correlations among these genes in SLE patients (P＜0.05). Conclusion The value of MX1, OAS1 and FFF44 expression level of SLE patients is up-regulated. The real time expression levels of OAS1, IFI44 genes are associated with SLE disease activity and there are close correlation among these genes with interferon induce virus-relationed genes (MX1, OAS1, IFI44) in SLE patients.

ObjectiveTo analyze the short-term efficacy of mastoscopic axillary lymph node dissection for the patients with early breast cancer who undergo breast-conserving surgery.MethodsThirty patients who met the standard of breast-conserving surgery were divided into two groups by random digits table with 15 cases each.All of these patients underwent breast-conserving surgery,then study group underwent mastoscopic axillary lymph node dissection while control group underwent open technique.The short-term efficacy was observed and compared between two groups.ResultsThe operation time in study group [(88.0 ± 18.0) min] was longer than those in control group [(68.0 ± 12.5) min] with significant difference (P =0.001 ).The incidence of upper extremity edema [ 6.7％ ( 1/15 ) ] and intercostobrachial nerve injury (0) in study group was lower than those in control group[60.0％(9/15),40.0％(6/15) ] with significant difference(P =0.002,0.022).There was no significant difference in blood loss,nodes harvest,total drainage volume and residual cancer cells between two groups [ ( 18.0 ± 12.2) ml vs.(21.3 ± 9.0) ml; 14.6 ±5.0 vs.16.4 ±3.6; (87.9 ±25.1) ml vs.(86.3 ±13.8) ml;6.7％(1/15) vs.13.3％(2/15)] (P ＞0.05).ConclusionsMastoscopic axillary lymph node dissection has the similar nodes harvest with open technique.The incidence of adverse reaction is lower,and the short-term effect is better.

Objective To investigate the effect of intermittent use of low molecular heparin (LMWH) on microembofic signal (MES) in patients with ischemic stroke on the basis of anti-platelet aggregation and statin therapy.Methods Ninety MES-positive patients with acute ischemic stroke detected by transcranial Doppler were randomly divided into a non-LMWH group (n =44) and a LMWH group (n =46).The non-LMWH group was treated conventionally with enteric-coated aspirin and atorvastatin.On the basis of conventional therapy,the LMWH group was treated with LMWH,subcutaneous injection of LMWH calcium 4 100 AXaIU every 3 months,twice a day,and one week as a course of treatment (a total of 3 courses).The number of MES,MES-positive rate and incidence of ischemic cerebrovascular events at 3 and 6 month were compared in both groups.Results There was no significant difference in the MES-positive rates at 3 month after treatment between the non-LMWH group and the LMWH group (70.45％ vs.61.36％ ;x2 =1.357,P =0.244),but the number of MES in the non-LMWH group was higher than that in the LMWH group (12.07 ± 10.16 vs.8.09± 8.13; t =1.470,P =0.043); the MES-positive rate at 6 month after treatment in the non-LMWH group was significantly higher than that in the LMWH group (36.96％ vs.19.57％;x2=3.982,P=0.046),and the number of MES in the non-LMWH group was also significantly higher than that in the LMWH group (10.32 ±9.93 vs. 1.46 ± 3.27; t =5.450,P =0.000).There was no significant difference in incidence of ischemic cerebrovascular events at 3 month (2.17％vs. 9.09％,P =0.198 ),but the incidence of ischemic cerebrovascular events at 6 month in the LMWH group was significantly lower than that in the non-LMWH group (4.35％ vs.20.45％,P =0.025).Conclusions On the basis of anti-platelet aggregation and statin therapy,the intermittent use of LMWH may decrease the MES-positive rate and the incidence of ischemic cerebrovascular events in the MES-positive patients with ischemic stroke at 6 month.
