Expression and significance of HERG protein in Cajal interstitial cells of gallbladder tissue in patients with gallbladder stones / 中华肝胆外科杂志

Objective:To investigate the expression and significance of human ether-a-go-go related gene (HERG) protein in interstitial cells of Cajal (ICC) in patients with gallbladder stones.Methods:The gallbladder tissues of 60 patients with gallbladder diseases who underwent cholecystectomy from January 2018 to December 2020 in the Faculty of Hepato-Pancreato-Biliary Surgery, Chinese PLA General Hospital were collected, including 36 males and 24 females, aged (46.0±14.0) years. They were divided into two groups according to whether there were gallstones: gallstone group and control group (patients with gallbladder polyps and gallbladder adenomyosis), with 30 cases in each group. Color ultrasound was used to detect and calculate the gallbladder contraction rate. The neck, body and bottom tissues of the gallbladder were excised and sectioned. The expression of HERG protein and CD117 ( marker of ICC) was detected by immunofluorescence staining, immunohistochemistry and Western blot.Results:The gallbladder contraction rate in the gallstone group was (65.8±4.1)%, lower than that in the control group (73.8±5.3)%, with a statistically significant difference ( t=4.14, P<0.001). Immunohistochemistry showed that HERG protein was mainly distributed in the mucosal layer of gallbladder tissue, which was pale brown. The relative expression of HERG protein at the bottom of gallbladder in the gallstone group was (0.293±0.102), lower than that in the control group (0.694±0.059), with a statistically significant difference ( t=3.38, P=0.027). Immunofluorescence staining showed that HERG protein was mainly distributed in ICC of gallbladder epithelium. HERG protein expression in ICC at the bottom of gallbladder in gallstone group was lower than that in control group, while HERG protein expression at the neck and body of gallbladder had no significant difference. Conclusion:There are ICC and HERG protein in gallbladder tissue of patients with gallstone. The decrease of gallbladder contraction rate may be related to the decrease of HERG protein expression in ICC in gallbladder bottom tissue.

Effect of Modified Chaihu Shugansan on Gallbladder Function and Inflammatory Cytokines Levels in Treatment of Chronic Cholecystitis Cholelithiasis / 中国实验方剂学杂志

Objective:To observe the clinical efficacy and influence of modified Chaihu Shugansan combined with ursodeoxycholic acid tablets on inflammatory factors in treatment of chronic cholecystitis cholelithiasis （stagnation of liver and gallbladder Qi）. Method:One hundred and ten patients were randomly divided into control group （60 cases） and observation group （60 cases）. Both groups received lifestyle intervention， and oral ursodeoxycholic acid tablets， 50 mg/time， taken in the morning and evening meals. Patients in control group additionally took Yidanshu capsules orally， 4 capsules/time， 3 times/day. Patients in observation group additionally took modified Chaihu Shugansan orally， 1 dose/day. The treatment courses continued 3 months in both groups. Before and after treatment， traditional Chinese medicine （TCM） symptom scores were graded， the ultrasound status of chronic gallbladder inflammation， gallbladder contraction function and stones was graded， the levels of interleukin-6 （IL-6）， IL-8， tumor necrosis factor-<italic>α</italic> （TNF-<italic>α</italic>） and nuclear transcription factor-<italic>κ</italic>B（NF-<italic>κ</italic>B）Were detected， and safety was evaluated. The efficacy for TCM syndromes， imaging efficacy and the efficacy for eliminating gallbladder stones were compared between the two groups. Result:The efficacy for TCM syndrome， efficacy on color ultrasound for chronic cholecystitis and the efficacy on imaging for cholelithiasis in the observation group were all better than those in the control group（<italic>Z</italic>=2.104<italic>，Z</italic>=2.076，<italic>Z</italic>=2.101，<italic>P</italic><0.05）. The thickness of gallbladder wall and volume of the gallbladder of the observation group were smaller than those of the control group （<italic>P</italic><0.01）， and gallbladder contraction function was higher than that in control group （<italic>P</italic><0.01）. Levels of IL-6， IL-8， TNF-<italic>α</italic> and NF-<italic>κ</italic>B in observation group were lower than those in control group （<italic>P</italic><0.01）. Conclusion:modified Chaihu Shugansan combined with ursodeoxycholic acid in the treatment of chronic cholecystitis and cholelithiasis （liver and gall Qi stagnation） is better than Yidanshu capsule combined with ursodeoxycholic acid sour scheme in terms of clinical efficacy， imaging efficacy， and elimination of gallbladder stones. It can reduce inflammation， and enhance gallbladder contraction， with high safety in clinical use.

Prospective study on changes in the donor gallbladder contraction function after left lateral lobe hepatectomy.

This study aimed to evaluate the feasibility of donor gallbladder preservation in liver transplantation. Conventional removal of the donor gallbladder is applied in a majority of pediatric liver transplantation. A total of 42 donors who underwent gallbladder preservation in liver transplantation from October 2013 to December 2015 at the Beijing Friendship Hospital, China, were enrolled for the study. The changes in gallbladder volume and the gallbladder EF of donors before and after surgery were measured through ultrasound, and the changes in the donor gallbladder contraction function before and after surgery were evaluated to help verify the feasibility of gallbladder preservation in living donor left lateral lobe hepatectomy. The gallbladder emptying index dropped to 42.67% in 2 weeks after surgery and gradually increased with the length of recovery time, which could reach 69.14% in 3 months after surgery. At that time, 97.6% of the donors were considered to have recovered their gallbladder contraction function. The gallbladder contraction function at an early stage after gallbladder preservation in liver transplantation is not obviously improved, but it can recover to a normal level in 1 month after surgery, indicating that the gallbladder preservation in hepatectomy of living donor can effectively guarantee the gallbladder contraction function.

A case of biliary atresia with pancreaticobiliary maljunction.

BACKGROUND: The pathogenesis of biliary atresia (BA) is still unknown. There are several reports on the etiology of BA, including pancreaticobiliary maljunction (PBM). We experienced a case of Kasai type IIIa BA with PBM, in which we found elevation of pancreatic enzymes in the gallbladder. We evaluated whether PBM is related to the pathogenesis of BA based on our findings. CASE PRESENTATION: The patient was born at 40 weeks of gestation. His body weight at birth was 2850 g. At the age of 4 days, he had an acholic stool and was referred to our hospital. Abdominal ultrasonography showed that triangular cord sign was negative. The gallbladder was isolated with a diameter of 19 mm, and it contracted in response to oral feeding. His ultrasonographic findings were atypical for BA, but his jaundice did not improve. Therefore, we performed an operation at the age of 56 days. Intraoperative cholangiography showed a common bile duct and pancreatic duct and a common channel patent, while the common hepatic duct or intrahepatic duct was not visualized. Bile in the gallbladder contained colorless fluid, which showed elevated lipase level (34,100 IU/L). We performed Kasai portoenterostomy under the diagnosis of Kasai type IIIa BA with PBM. The patient's postoperative course was uneventful, and he was discharged on day 30 after the operation. Histopathological evaluation showed that the lumens of the common bile duct and cystic duct were patent. However, the common hepatic duct was closed, and only bile ductules with diameters of less than 50 µm were isolated. Infiltration of lymphocytes was detected in the porta hepatis. No apparent inflammation was observed around the cystic duct, which was constantly exposed to pancreatic juice because of reflux through PBM. CONCLUSIONS: Reflux of pancreatic juice through PBM might not be an etiological factor for BA, but might be associated with patency of the common and cystic bile ducts in Kasai type IIIa BA.

A New Reliable Method for Evaluating Gallbladder Dynamics: The 3-Dimensional Sonographic Examination.

OBJECTIVES: The purpose of this study was to compare conventional 2-dimensional (2D) B-mode sonography with 3-dimensional (3D) sonography for assessing gallbladder volume and contractility. METHODS: Gallbladder volume and contractility were evaluated in 32 healthy volunteers after fasting and abstinence from smoking for 8 hours and after a standardized balanced liquid meal. The gallbladder was evaluated with 2D sonography (with the use of the ellipsoid method) and with 3D sonography using a volumetric matrix probe. Both measurements were made by an operator who was skilled in sonography and an unskilled operator. The group of volunteers was subdivided into 2 subgroups including 16 participants, which represented the "2 moments" of acquisition by the techniques, particularly for the unskilled operator. RESULTS: The postprandial volumes obtained with 3D sonography were significantly lower in comparison to the volumes obtained with 2D sonography (P= .013), and there was a significant difference between the measurements made by the skilled and unskilled operators only for 2D sonography (P< .001), whereas between the 2 moments of acquisition by the 3D technique, there was no significant difference. The reproducibility of the technique for evaluation of gallbladder volumes was higher for 3D sonography than 2D sonography, particularly for the postprandial evaluation. CONCLUSIONS: The new 3D sonographic method using a volumetric matrix probe is a simple, reliable, and more reproducible technique than conventional 2D sonography, even if performed by an unskilled operator, and it allows a reliable stimulation test for a gallbladder dynamic study.
