Objective To evaluate the effect of combined laparoscopic and endoscopic treatment for cholelith of gallbladder and common bile duct(CBD).Methods Diagnosis was established in 44 patients by ERCP , and endoscopic Oddi′s sphincteromy (EST) was performed in all patients, then choledocholith was removed by endoscopic netbasket and balloon. 3～5 days after laparoscopic cholecystectomy(LC) was carried out. Results The success rate of combined treatment in this study was 98%(43/44), and stones were removed in 100%(44/44). There was no conversion to open surgery in our series, and no severe complications. All patients were discharged in 5～15 days postoperatively. Conclusions Combined laparoscopic and endoscopic procedure is a safe and effctive method to treat patients suffering from cholelith of the gallbladder and CBD.

OBJECTIVE：To analysis the correlation between chrom aticity value and quality index of Atractylodis chinensis decoction piece powder stir-fired with bran ，and to determine its processing time. METHODS ：The processed samples of 16 batches of A. chinensis decoction piece stir-fired with bran （S0-S15，S0 is the raw product of A. chinensis ）were prepared ，and chromaticity values of all samples were determined ，such as lightness value （L*），yellow blue value （b*），red green value （a*）. UPLC fingerprint of sample were analyzed ，and the contents of extract and volatile oil were also determined. Pearson correlation was used to analyze the correlation between the chromaticity value and quality index （relative peak area of each chromatographic peak in UPLC fingerprint ，water-soluble extract content ，alcohol-soluble extract content and volatile oil content ）. Multivariate statistical analysis （principal component analysis ，cluster analysis ，partial least squares discriminant analysis ）was carried out with chromaticity value and quality index ，and the processing time of A. chinensis decoction piece stir-fired with bran was determined by grey correlation method. RESULTS ：In the process of bran frying ，with the extension of processing time ，L* and b* of decoction pieces powder decreased ，and a* increased first and then decreased ；relative areas of peak 1 and peak 2 increased first and then decreased，while relative areas of peak 3（5-hydroxymethyl furfural ）increased，and the areas of the other peaks decreased. The content of the extract did not change significantly with time ，and the content of the volatile oil decreased. The results of correlation analysis showed that the relative peak area of peak 2-27，alcohol-soluble extract content and volatile oil content had a certain correlation with the chromaticity value ，while the relative peak area of peak 1 and water-soluble extract content had no linear correlation with the chromaticity value. Results of multivariate statistical analysis showed that the samples were divided into mild （S0-S5），excessive （S12-S15），moderate （S6-processing time of 18-33 min）. The results of grey correlation method showed that the processing time of A. chinensis decoction piece stir-fired w ith bran should be controlled in the range of 18-24 min，and the optimal processing time was 18 min. CONCLUSIONS ：There is a correlation between chromaticity value of A. chinensis decoction piece powder stir-fired with bran and the relative peak area of 27 chromatographic peaks ，and content of extract and volatile oil. It is suggested that the processing time should be 18 min.
