Wingless type protein (Wnt protein) is a group of protein which plays an important role in the process of animal growth and hemopoiesis,the signaling pathway they conducted was called Wnt signaling pathway,and its abnormal activation can lead to many tumors,include lung caner.As a tumor suppressor gene,WIF-1 can restrain the activation of Wnt signaling pathway,which can avoid lung cancer.WIF-l's methylation can downregulate the expression of WIF-1,which can activate Wnt signaling pathway and cause lung cancer.So the detection of WIF-1's methylation may contribute to clinical diagnose of lung cancer,and therapy of WIF-1 's methylation may be one of the treatment metheds of lung cancer.

Methods 34 patients were diagnosed as sactosalpinx with sonography. They were confirmed by sactosalpingography. Results Sactosalpinx showed long-bar or a cystic shape twisty liquid dim areas in adnexa site. There were incomplete septaligth band in it.Conclusions sactosalpinx can be detected by transvaginal sonography. It has great significance to guide the treatment and other examinations related to infertility.

In order to assess colonic motility of chronic constipation, colonic transit test was carried out in 34 patients with chronic constipation and in 20 healthy subjects. 20 radiopaque markers are ingested at 8 am before the day test, and plain abdominal films were obtained at 24 h, 48 h and 72 h. The normal value of colonic transit test was 16(80%), or more markers passed after 72 h. By means of transit time study, 34 constipated patients were classified into 2 groups: 12 normal transit patients and 22 slow transit patients. There was no difference in colonic transit time between normal transit patients and controls (P＞0.05). Patients with slow transit had more markers left in right colon, left colon and rectosigmoid colon at 48 h (P＜0.01, respectively) and 72 h (P＜0.01, respectively). According to the transit index, 22 slow transit patients were divided into 3 types: 10 cases colonic stasis, 8 cases outlet obstruction and 4 cases colorectal stasis. The study suggests that chronic constipated patients have abnormalbilities of colonic transit.

Objective To explore the feasibility and effect of intervention therapy for patients subclavian steal syndrome.MethodsThe data of 35 patients with subclavian artery steal syndrome in neurology department of our hospital from October 2014 to March 2016 were retrospectively analyzed.All patients treated with pecutaneous transtuminl angioplasty and stenting.The degree of vascular stenosis was measured by digital subtraction angiography, the inter-arm blood pressure was tested by mercury sphygmomanometer.And the clinical manifestations before and after surgery were compared.All patients were followed up for 1 to 12 months,the clinical manifestations,blood flow and vascular stenosis degree in patients were observed.Results All patients were finished pecutaneous transtuminl angioplasty and stenting successfully,7 patients with serious vascular stenosis treated with percutaneous intravascular balloon dilatation at first.The average artery stenosis before operation was(74.73±10.42)%,while it decreased to(8.60+3.16)% after surgery,which were measured by DSA,the difference was significant(P<0.01).The result from mercury sphygmomanometer showed that the inter-arm blood pressure from preoperative(44.43±10.12)mmHg to postoperative (10.09+4.80)mmHg (2~7 days),systolic blood pressure differential minified significantly,the difference was significant(P<0.01).All patients were followed up for 1 to 12 months,support forms of 34 cases were in good conditions without new narrow,1 case appeared narrow in postoperative 7 months,then recovered after reoperation;symptoms of 28 cases significantly improved or disappeared,5 cases partly alleviated,2 cases had recurrence,no serious complications such as thrombosis and severe infarction occurred.Conclusion The pecutaneous transtuminl angioplasty and stenting is stable,high successful and low short-term recurrence rate for subclavian steal syndrome,which is good to alleviate vascular stenosis,reduce interrm blood pressure difference and improve clinical manifestation.

Objective To analyze the medium and long-term results of tricuspid valve replacement (TVR)and summarize the operative experience for tricuspid valve disease.Methods Clinical data of 27 patients with severe tricuspid valve disease from September 2005 to May 2010 were retrospectively reviewed.Biological valve prosthesis was replaced in 23 patients,while mechanical valve prosthesis was replaced in 4 patients.Accompanying procedures included mitral valve replacement in 8 cases,mitral valve replacement and aortic valve replacement in 4 cases,and repair of atrial septal defect in 4 cases.Results The operative mortality was 11.1％(3/27),among these patients,2 cases died of serious low cardiac output syndrome,1case died of muhiorgan failure on the 7th day after operation,1 case who underwent reoperation for hemorrhage postoperative was improved after treatment.During follow-up,1 patient died of biological valve prosthesis dysfuncion 3 years after operation,1 patient died of cerebral embolism 19 months after operation.Six cases were in New York Heart Association(NYHA)class Ⅰ,and 14 cases in NYHA class Ⅱ during the period of follow-up.Conclusions Because operative and follow-up mortality is high,TVR is the last selection for the treatment of tricuspid valve disease.Appropriate operative technique and perioperative therapy are the key for clinical success.For those older than 50 years,follow-up inconvenience and reproductive-age female patients,biological valve prosthesis should be recommended as a preferential choice.

Objective To explore the clinic effect of intravascular stent angioplasty for extracranial internal carotid artery dissection(ICAD).Methods From July 2015 to December 2016, 25 cases of patients with extracranial ICAD were admitted into our hospital.Among them, there were 15 cases of head and neck pain,12 cases with transient ischemic or cerebral infarction symptoms (limb hemiplegia.etc.),6 cases of Horner syndrome,1 case with pulsatile tinnitus and syncope,2 cases with no obvious clinical symptoms which were found by the neck vascular ultrasound accidentally.All patients were treated with intravascular stent angioplasty.Calculated the degree of stenosis through digital subtraction angiography(DSA),measured the blood flow velocity with transcranial doppler(TCD),and observed the clinical manifestations.Reviewed those patients after six months.Results Totally 24 patients with ICAD fulfilled the intravascular stent angioplasty with no complications such as lining damage,bleeding and embolism.And one patient with ICAD abandoned intravascular stent angioplasty for the vascular is too circuity.DSA showed the average artery stenosis decreased from (76.70±10.57)% preoperatively to (11.07±4.18)% immediately after operation,and the difference was statistically significant(P<0.01).TCD measured the peak systolic velocity (PSV) of internal carotid artery stenosis segment,and the PSV changed from (189.55±54.27)cm/s averagely before operation to (88.41±17.06)cm/s on average one week after operation.The difference was statistically significant (P<0.01).Reviewed the head and neck CT angiography (CTA) after 6 months.There were 23 cases without new stenosis and 1 case had stent restenosis compared with CTA immediately after operation.Symptoms of 19 cases obviously remitted or disappeared,4 cases partially remitted,and recurrence occured in 1 patient.There was no appearance of infarction and other serious complications.Conclusion The intravascular stent angioplasty is relatively safe and effective for extracranial ICAD, which can remit the degree of stenosis,slow down the blood flow and relieve the clinical symptoms with low recent recurrence rate and adverse reaction.But it does not apply to patients with severe vascular circuity.
