A number of methods are currently employed to assess the functional properties of CFTR channels and their response to pharmacological potentiators, correction of the defective CFTR trafficking, and vectorial introduction of new proteins. Here we review the most common methods used to assess CFTR channel function. The suitability of each technique to various experimental conditions is discussed. 相似文献

The historical evolution of the pylorus-preservation resection of the head of the pancreas is traced from the first resections
early in this century to relative standardization of the operation, to a lowering of the operative mortality, and to an interest
in improving nutritional status after resection. There are many theoretical advantages for the function of the upper gastrointestinal
tract after pylorus and gastric preservation, such as maintenance of gastric capacitance and equilibration of osmotic pressure
in gastric digestants, foodstuff digestion and absorption, and bowel motility. After the pylorus-preserving resection, gastric
emptying is normal, pyloric function to prevent duodenal reflux is often normal, and gastric acids and serum levels of duodenal
hormones are at normal levels, whereas after standard pancreatoduodenectomy, all of these are often abnormal. No prospective
blinded studies have been published comparing nutritional values after the two operative procedures, but evidence is presented
of a satisfactory result with regard to gastric capacitance, body weight gain, and lack of postgastrectomy symptoms. An undoubted
advantage of the pylorus-preserving feature is a simplification of the operation. These gains are achieved without increase
in operative mortality, without increase in the incidence of jejunal ulcer, and without theoretical or actual decrease in
value of the procedure as a cancer operation, except in patients with duodenal carcinoma proximal to the ampulla of Vater. 相似文献

目的:研究下颌牙弓的有效后移量及找寻下颌牙弓移动的后界。方法:选取涉及拔除下颌第三磨牙或下颌第三磨牙缺失的病例18例(男6例,女12例)。采用种植支抗牵引下牙弓向远中,治疗完成时所有病例均明确到达下颌牙弓后界,即下颌第二磨牙远中到达下颌升支前缘软组织交界处。应用治疗前后的曲断片测量下颌第二磨牙远中到升支前缘的距离。结果:下颌第二磨牙后移量为(3.49±1.21)mm;治疗后磨牙后间隙的长度为(4.43±0.97)mm。结论:下颌牙弓可确定性地实现整体后移;最大后移量由磨牙后间隙的长度决定;其最后界止于下颌第二磨牙远中与下颌升支前缘软组织交界处。 相似文献

ObjectiveComplex base fractures of the fifth metacarpal bone and dislocation of the fifth carpometacarpal joint are more prone to internal rotation deformity of the little finger sequence after fixation with a transarticular plate. In the past, we have neglected that there is actually a certain angle of external rotation in the hamate surface of transarticular fixation. This study measured the inclination angle of the hamate surface relative to the fifth metacarpal surface for clinical reference.MethodsIn a prospective single‐center study, we investigated the tilt angle of 60 normal hamates. The study included thin‐layer computed tomography (CT) data from 60 patients from the orthopaedic clinic and inpatient unit from January 2017 to March 2020, including 34 men and 26 women who were 15~59 years old, average 35 years old. The CT data of 60 cases in Dicom format of the hand was input into Mimics and 3‐Matics software for three‐dimensional (3D) reconstruction and measuring the angle α between hamate surface and the fifth metacarpal surface. According to the possible placement of the transarticular plate on the fifth metacarpal surface, we measured the angle β between the hamate surface 1 and the fifth metacarpal surface and the angle γ between the hamate surface 2 and the fifth metacarpal surface.ResultsThe average angle between the hamate surface and the fifth metacarpal surface was 11.66°. The hamate surfaces 1 and 2 have an external rotation angle of 7.30° and 7.51° on average with respect to the fifth metacarpal surface, respectively. There is no statistically significant difference in the angles between the two groups (P > 0.05).ConclusionsThe horizontal angle of the dorsal side of the hamate is different from the back of the fifth metacarpal surface, and the hamate has a certain external rotation angle with respect to the fifth metacarpal surface. No matter how the transarticular plate is placed, the plate always has a certain external rotation angle relative to the fifth metacarpal surface. When the fixation is across the fifth carpometacarpal joint, if the plate does not twist and shape, it will inevitably cause internal rotation of the fifth metacarpal, resulting in internal rotation deformity of the little finger sequence. 相似文献

Whipple's pancreatoduodenectomy was the standard operation for diseases of the head of the pancreas for more than 40 years,
but the results were vitiated in part by poor gastrointestinal function and malnutrition. Reintroduced in 1978, pylorus-preserving
proximal pancreatoduodenectomy (PPPP) has had an increasing impact on pancreatic surgery as its benefits have been recognized:
improved nutritional status, decreased incidence of postgastrectomy syndromes, and a technically easier operation. Postoperative
mortality rates and 5-year survival rates are comparable with those of the classic Whipple procedure. PPPP is indicated for
most patients with chronic pancreatitis of the pancreatic head. It is also appropriate for patients with periampullary cancer
and for those with pancreatic cancer arising from the lower part of ‘the head and the uncinate process. More than 650 patients
have now undergone PPPP: 31% for chronic pancreatitis and 66% for periampullary and pancreatic cancers. We assess the indications
for PPPP, outline the operation, and review the results. 相似文献
