Objective To investigate whether the vohage-gated chloride channel CLC-2 gene— CLCN2 is associated with idiopathic generalized tonie-clonic seizures(often called a grand mal seizure, GME)of Jinuo people and Han people from Yunnan province.Methods Three regions,including Intron 2, Exon 5 and Exon 19(Intron 18),of CLCN2 were selected to conduct sequence analysis.The case-control study design was used to detect association between gene polymorphism and idiopathic generalized tonic- clonic seizures of Jinuo people and Han people from Yunnan province.Results No previously reported susceptible mutations were found in Intron 2,Exon 5 and Exon 19 in Jinuo people and Han people from Yunnan province.However we found a single nucleotide polymorphism(SNP)at site 146 of Intron 18. Case-control study were carried out,using this SNP.Distribution of the 3 genotypes(TT,TC,CC)has a significant difference between the IGTCS patients of Han people and the normal controls of Han people(9, 3,29 cases and 22,9,26,respectively,x~2=16.079,P

Objective To probe the effects of nuclear factor kappa B (NF-?B) on cell apoptosis and left ventricular segmental function in acute ischemia repeffusion in dogs.Method Twenty-four dogs were randomly divided into three groups:without left anterior artery (lAD) ligation group (C group),LAD was occluded 30 min following reperfusion 120 minutes in isehemical reperfusion group (IR group),and dogs were administered with PDTC before LAD ligation in ischemical reperfusion plus pyorrole dithitocarbamate group (PDTC group).The left ventricular segmental function was detected by echo cardiography using strain rate anlysis software.EF measured by Simpson's method.Cardiac myocyte apoptosis numbers were determined by terminal deoxynudeotidy transferease-mediated biotinylated deoxyuridine triphosphate nick end labeling (TUNEL).lmmunohistochemistry and western-blot anylysis of NF-?B protein expression.Results NF-?B was obviously expression on injury myocardium of IR group,and increased significantly in contrast to control group (P0.05)Conclusions NF-?B might play an important role in acute myocardial ischemia reperfusion.PDTC reduces myocardial iscbemia/repeffasion injury by preventing expression of factor NF-?B.

OBJECTIVETo evaluate the distribution of CD4+ CD25+ regulatory T-cells (T-regs) in tumor-draining lymph nodes (TDLN) in patients with non-small cell lung caner (NSCLC), and to investigate the effect of CD4+ CD25+ T regulatory cells on the immune status of TDLN and the progression of NSCLC.

METHODSRegional tumor-draining lymph nodes of 53 NSCLC patients were resected during the operation. The percentage of CD4+ CD25+ T-regs as a subset of CD4+ T cells and CD8+ T cells were detected by immunofluorescence and regular immunohistochemistry, respectively. The level of cytokines TGF-beta1 and IL-10 was detected by real time quantitative RT-PCR.

RESULTSCD4+ CD25+ T-regs in tumor-infiltrating lymph nodes from the patients with NSCLC accounted for 28.80% +/- 8.06% of total CD4+ T cells, and were significantly increased comparing with that (15.48% +/- 4.66%) in the tumor-free lymph nodes (P < 0.01). The percentage of CD4+ CD25+ T-regs in TDLN of NSCLC patients was negatively correlated with the amount of CD8+ T cells within the lymph nodes (r = -0. 756, P < 0.001), but positively correlated with the level of TGF-beta1 (r = 0.645, P < 0.001) and IL-10 (r = 0.769, P < 0.001). It also increased as NSCLC getting progressed, which was 30.42% +/- 7.47% in stage III versus 16.22% +/- 4.88% in stage I and III; 32.58% +/- 7.52% in N2 versus 22.76% +/- 4.67% in N1, with a significant difference between the two groups, respectively (P < 0.01).

CONCLUSIONThe population of CD4+ CD25+ T regulatory cells in tumor-draining lymph nodes in patients with non-small cell lung caner is positively correlated with the progression and infiltration of lung cancer, which might provide new immunologic method to evaluate the progression and prognosis of non-small cell lung caner. The outcomes of biotherapy for NSCLC may be improved in the future through regulating the CD4+ CD25+ T regulatory cells.

For a minimally invasive approach to access the facial nerve, we designed an extended epitympanotomy via a transmastoid approach that has proven useful in cases of traumatic facial nerve palsy and pre-cholesteatoma. To evaluate the surgical exposure through an extended epitympanotomy, six patients with traumatic facial nerve palsy were enrolled in this study. The same surgical technique was used in all patients. Patients were assessed and the degree of facial nerve paralysis was determined prior to surgery, 1-week post-operatively, and 6-months post-operatively using the House-Brackmann grading system. In all cases, surgical exposure was adequate. All patients with traumatic facial nerve palsy were male and the age range was 13 to 83 years. In all cases, the location of the facial nerve damage was limited to the area between the first and second genu. Symptoms of all the patients improved by 6 months post-operation (p=0.024). There were no complications in any of the patients. Extended epitympanotomy is useful for safe, rapid surgical exposure of the attic area, sparing the patient post-operative dimpling, skin incision complications, and lengthy exposure to anesthesia. We suggest that surgery for patients with facial nerve palsy secondary to trauma be performed using this described technique.

ObjectiveTo discusse the relationship between static balance in laboratory approaches and dynamic balance in clinical assessment and identify the value of static and dynamic balance at functional outcome in hemiparetic stroke patients. MethodsNineteen stroke subjects were assessed in this study. The static balance was measured by postural sway test, the dynamic balance was measured by Berg balance scale(BBS)and Time up to go test(TUGT),the outcome was measured by FIM and 10m maximum walking speed(MWS). The level of association between the parameters of postural sway test and clinical variables were examined with Pearson's correlation coefficients. ResultsThe parameters of postural sway test was significantly negative related to BBS(r=-0.705--0.475,P<0.05);The parameters of postural sway close-eye test was significantly positive related to TUGT(r=0.508-0.583,P<0.05);The parameters of postural sway test was no related to FIM and MWS (r=-0.048--0.296;r=-0.404--0.01,P>0.05);BBS was significantly positive related to FIM and MWS(r=0.752;r=0.700,P<0.001). TUGT was significantly negative related to FIM and MWS(r=-0.600,P<0.01;r=-0.817,P<0.001).ConclusionClinical and laboratory balance assessments are related and that dynamic rather than static balance measures are valid indicators of functional outcome performance in hemiparetic stroke patients.

Background:The preferred treatment for uncomplicated type B dissection (thoracic endovascular aortic repair [TEVAR] or medical) is still under debate.Since 2001,our center has performed TEVAR for uncomplicated type B dissection.Based on our data,5-and 10-year survival rates among patients with uncomplicated type B dissection after TEVAR were 96.5％ and 83.0％,respectively.We,therefore,believe that TEVAR is preferable for uncomplicated type B dissections.This study analyzed the impact of a pre-operative smoking history on long-term survival after TEVAR in patients with uncomplicated type B dissections.Methods:From May 2001 to December 2013,data from 751 patients with type B dissections were collected and analyzed.Patients were divided into two groups (337 smoking patients and 414 non-smoking patients).The Kaplan-Meier method and log-rank test were used to compare survival curves of the two groups.Multivariable analyses using the Cox proportional hazards model were used to estimate the effects of smoking on survival rates.Results:The 5-and 10-year survival rates of non-smokers were 97.6％ (95％ confidence interval [CI],96.0％-99.2％) and 87.0％ (95％ CI,81.6％-92.7％),respectively,and 94.9％ (95％ CI,92.2％-97.7％) and 73.8％ (95％ CI,62.3％-87.5％) for smokers,respectively (Log-rank test,P =0.006).Multivariable analyses showed that smoking increased the risk of death during follow-up,2.1-fold when compared to non-smokers (P =0.039).Conclusion:A pre-operative smoking history increases long-term mortality rates after TEVAR in patients with uncomplicated type B dissections.

Objective To investigate the CT findings of Madelung's disease in the head and neck region,and to evaluate the value of CT in demonstrating the Madelung's disease in the head and neck region.Methods CT findings of Madelung's disease in the head and neck region in 7 cases were analyzed retrospectively.All were males,with the age from 36 to 60 years,mean 51 years.All patients were underwent CT native scan,and enhanced CT scan was performed on 3 of them.Results CT images in the neck of all patients showed accumulation of nonencapsulated fat within the subcutaneous tissue and(or) deep to the platysma,and(or)within the spaces between the muscles.The fat deposits were ill-defined and symmetrical.In most cases the fat deposits involved the anterior part of the neck(infrahyoid and suprahyoid),submandibular region,the subcutaneous tissue of the nape and deep to the stenomastoid muscles.Conclusions Madelung's disease in the head and neck region have characteristic CT findings,and CT has great value in qualitative and quantitative diagnosis in Madelung's disease.

Objective To study the epidemical characteristics of influenza/novel influenza A (H1N1) in Shanxi province from 2009 to 2010, and to provide scientific foundations for predicting and controlling the pandemic outbreak of influenza/novel influenza A (H1N1) effectively. Methods All samples were collected from cases that resemble influenza cases in sentinel hospital and influenza outbreak.The influenza were detected by PCR and isolated by MDCK cell culture method. Finally, Shanxi province surveillance data from May, 2009 to April, 2010 of influenza like illness (ILI) cases and pathogen detections were analyzed. Results In Shanxi province, influenza viruses kept activation in whole year. The predominant pandemic strain in 2009 was novel influenza A (H1N1) virus. The strong peak was around November, 2009 [positive rate: 58.1% , novel influenza A( H1N1 ) of the total: 88. 1%]. As well, the people infected influenza caused by novel influenza A (H1N1) were mainly under 59-year-old, and the higher positive rates were concentrated in the people from 5-year-old to 24-year-old. In 2010, influenza B (Victoria) viruses were mainly detected from clinical specimens and became the dominant strain.Conclusion: Surveillance of Influenza liue illnes, (ILI) and etiology, which can promptly reflect the influenza epidemic situation, play a significant role for understanding epidemic rule of influenza/novel influenza A( H1N1 ).

OBJECTIVETo investigate risks and clinical effects of operative treatment for cervical vertebral fracture and dislocation associated with unilateral vertebral artery injury.

METHODSThis group consisted of 76 cases of closed cervical spine trauma combined with unilateral vertebral artery injury (23 cases of bilateral facet dislocation, 28 unilateral facet dislocation and 25 fracture). All patients underwent prospective examination of cervical spine MRI and vertebral artery two-dimensional time-of-flight (2D TOF) magnetic resonance angiography (MRA), and anterior cervical decompression. The healthy vertebral artery paths were evaluated before the surgery, and were protected during the surgery according to the anatomical signs.

RESULTSThere were no acute or chronic clinical damage symptoms in 76 cases after surgery. No neural damage symptoms were observed in patients with normal neural functions. The neural functions of incomplete paralyzed patients were improved in different grades.

CONCLUSIONSReliable anterior operation can produce good results for cervical fracture and dislocation with unilateral vertebral artery injury. Detecting the course of uninjured vertebral artery before operation and locating the anatomical site during operation are effective to avoid damaging vertebral artery of uninjured side.
