ObjectiveTo investigate the causal relationship between gut microbiota and cholelithiasis using a two-sample Mendelian randomization method. MethodsThe genome-wide association studies (GWAS) data of gut microbiota from the MiBioGen study and the GWAS data of cholelithiasis from the FinnGen Biobank were utilized. Genetic variants significantly associated with the relative abundance of gut microbiota were identified as instrumental variables (IVs) based on a specified threshold. The inverse variance weighted (IVW) method was employed as the primary analytical approach, with results assessed based on the odds ratio (OR) and 95% confidence interval (CI). The robustness and reliability of the findings were ensured through quality control measures, including sensitivity analysis, assessment of heterogeneity, and evaluation for horizontal gene pleiotropy. ResultsClostridiumsensustricto1 [OR=1.160, 95%CI (1.023, 1.314), P=0.020], Coprococcus3 [OR=1.136, 95%CI (1.014, 1.272), P=0.028] and Peptococcus [OR=1.074, 95%CI (1.023, 1.128) , P=0.004] increased the risk of cholelithiasis. Bacilli [OR=0.897, 95%CI (0.818, 0.984), P=0.022], Family Ⅹ ⅢAD3011group [OR=0.908, 95%CI (0.830, 0.992), P=0.033] and Lactobacillales [OR=0.884, 95%CI (0.802, 0.974), P=0.013] were protective factors for cholelithiasis. ConclusionThe study has identified 6 kinds of specific gut microbiota that are causally linked to the development of cholelithiasis, providing new ideas for the diagnosis and treatment of cholelithiasis.

Objective To evaluate the effectiveness and safety of Chinese medicine treatment of cholelithiasis. Methods We searched electronic databases including MEDLINE (1966 to Feb. 2009), EMbase (1974 to Feb. 2009), The Cochrane Library (Issue 4, 2008), Chinese Biomedical Literature Database (CBM, 1978 to Feb. 2009), CJFD (CNKI, 1994 to Feb. 2009), the Chinese Scientific and Technical Journals database (VIP, 1989 to Feb. 2009), and a database of Chinese biomedical journals (CMCC, 1994 to Feb. 2009). At the same time, we searched references of the included studies. Metaanalysis was performed using RevMan 5 if there was no significant heterogeneity. We described the date which could not be combined. Results A total of 18 randomized controlled trials involving 2 276 patients were included. According to measurement indicators and interventions, subgroup analysis was performed. Efficacy was reported in 10 studies, which showed that part of proprietary Chinese medicines had a higher efficiency for cholelithiasis. Gallbladder emptying index and the trend of bile into the stone were compared in 5 studies, suggesting that the bile of proprietary Chinese medicines reduced the stone index, which eased the bile tendency to rock. Three studies reported the rate of cholecystokinin. Metaanalysis results suggested that the difference was significant. Two studies reported adverse drug reactions (ADRs), such as epigastric discomfort and diarrhea. Most ADRs were slight, and could be self relieved. Conclusion Results suggest that Chinese medicines produce effects on clinical symptoms of cholelithiasis, gallbladder function and reduce the trend of bile into stones. However, the therapeutic effects for long-term are rarely reported. The conclusion needs further verification due to low methodological quality and apparent heterogeneity.
The conectration of cholecystokinin infasting serum was determined by radioimmunoessay in 30 patients with gastric antrum cancer before and after radical sbutotal gastrectomy.It was 119.6±142.2pmol/L before the operation and 78.5±149.2pmol/L after the operation,which was significantly lower than that before the operation,P=0.022. The result suggests that the reduction of cholecytokinin secretion after gastrectomy was one of the important causes in the bile stasis,the disturbance of gallbladder emptying funcion and the formation of gallstone.
【Abstract】ObjectiveTo improve curative effects in the treatment of hilar bile duct stricture. MethodsIntrahepatic cholelithiasis was associated with the development of hilar bile duct stricture.Plastics of hilar bile duct stricture (PHBDS) using pedicled cholecystic graft and Roux-en-Y cholangiojejunostomy (RYCJ) were performed. The patients with hepatolithiasis treated with PHBDS or RYCJ between Jan. 1994 and Jan. 2004 were retrospectively analyzed.ResultsFollow-up was carried out from 16 months to 87 months with an average of 47 months. The postoperative morbidity of cholangitis was 5.66% and 21.88% (P=0.010) and recurring rate of hepatolithiasis was 3.77% and 16.67%(P=0.021).ConclusionPHBDS can preserve the physiological compatible, convenient and effective in treatment of hilar bile duct stricture. The late result after operation of PHBDS is better than that of RYCJ.
ObjectiveTo study the clinical value of procalcitonin (PCT), WBC count, and C-reactive protein (CRP) in diagnosis of common bile duct stones with acute bile duct infection and systemic inflammatory response syndrome (SIRS).MethodsA total of 80 patients with bile duct stones were retrospectively analyzed, which were divided into two groups, SIRS group (n=40) and non-SIRS group (n=40). The numerical value of PCT, WBC count, and CRP were detected on 1, 4, and 7 day after admission, and calculated the score of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) on 1 day after admission. Then analyzed the clinical value of PCT, WBC count, and CRP in diagnosis of common bile duct stones with acute bile duct infection and SIRS.ResultsEach area under the ROC curve of PCT, CRP, and WBC count were 0.81, 0.78, and 0.72, respectively, with significant difference (P<0.05). The PCT, CRP, and WBC count had a certain accuracy in diagnosis of common bile duct stones with acute bile duct infection and SIRS. The positive-relationship between PCT, CRP, WBC count and APACHE Ⅱ score was significant (r=0.91, P<0.01; r=0.88, P<0.01; r=0.69, P<0.01).ConclusionTo detect the numerical value of PCT, WBC count, and CRP had significant clinical value in diagnosis of common bile duct stones with acute bile duct infection and SIRS.
Objective To investigate the recurrence of hepatolithiasis and reoperation and their relation to the location of intrahepatic stone. MethodsTwo hundred and twentysix patients of hepatolithiasis operated upon in the period of 1990-1995 were retrospectively analysed.ResultsAmong those patients, there were 101 patients (44.7%) had previous operation for the gallstones diseases including cholecystectomy for gallbladder stones (n=21, 20.8%), choledocholithotomy (n=72, 71.3%),liver segmentectomy (n=6， 5.9%), and choledochojejunostomy (n=2, 2.0%). The operative mortality was 5.0% for the reoperation group and none for the first time operation for hepatolithiasis.Conclusion Although the liver resection is an ideal surgical method to eradicate the diseased lesion and to minimize the malignant changes especially in primary hepatolithiasis (type I, or IE)， choledochojejunostomy is only recommended for the secondary type (type IE or IE) where possible. In the management of hepatolithiasis, the complete information of biliary tract is needed for the choice of surgical methods.
目的:探讨门静脉高压症(Portal hypertension,PHT)合并胆石症的合理处理方式。方法:回顾分析2003年9月于2008年9月64例PHT合并胆石症患者不同方式手术治疗的结果。根据手术方式不同将64例患者分为三组。A组:仅行胆道手术(n=20);B组:在行PHT手术的同时行胆道手术(n=20);C组:在行PHT手术时对胆囊或胆道结石未作处理(n=24)。结果:死亡率A组10%,B组28.5%,C组4.3%。并发症:A组40%,B组70%,C组25%。结论:PHT合并胆石症无论仅行胆道手术或同期行PHT手术和胆道手术,手术死亡率和术后并发症均显著增加,尤以同期手术为明显。根据患者情况选择正确的手术方式,可有效降低手术风险。
Objective To evaluate the methodological and reporting quality of randomized controlled trials involving traditional Chinese medicine in the treatment of cholelithiasis. Methods We searched CNKI (1994 to 2007), CMCC (1994 to 2007), VIP (1989 to 2007), MEDLINE (1966 to April 2007) and The Cochrane Library (Issue 4, 2006). Data from randomized controlled trials (RCTs) and quasi-RCTs were extracted by two reviewers independently. The methodological quality of included trials was assessed by using the quality assessment criteria recommended by The Cochrane Collaboration, and the reporting quality was assessed by using the CONSORT for TCM checklist. Results Seventeen studies including 16 RCTs and one quasi-RCT were included. The methodological and reporting qualities of included studies were generally low. All studies were graded C. The highest score evaluated by the CONSORT for TCM checklist was 18. Conclusion The quality of RCTs and quasi-RCTs involving traditional Chinese medicine for cholelithiasis is generally low, with a high risk of biases. The reporting of these trials is also incomplete, which would affect a reader’s understanding and evaluation of the validity, importance and applicability of the study results. Therefore, new randomized controlled trials of high quality are required to provide reliable evidence.
