The objective of the study is to identify the effective common Chinese herbal medicines used in treating chronic cholecystitis with liver-gallbladder dampness-heat syndrome(CCLGDHS) through reviewing relevant clinical studies published in the past 10 years. Data were collected from Science Direct and Chinese National Knowledge Infrastructure. Data screening was carried out for the abstracts and full texts of the data. The top 15 Chinese herbal medicines with the highest occurring frequency were selected, statistically analyzed, and classified by their medicinal properties, actions, and indications according to the Chinese Pharmacopoeia 2015 edition. The top 15 effective common Chinese herbal medicines comprise Chai Hu, Huang Qin, Jin Qian Cao, Bai Shao, Yin Chen, Yu Jin, Chuan Lian Zi, Yan Hu Suo, Zhi Shi, Ban Xia, Bai Zhu, Pu Gong Ying, Gan Cao, Zhi Zi, and Qing Pi. The predominant natures were cold, cool, and warm. This combination can clear stagnant heat, warm Yang, and regulate Qi dynamics. In addition, bitter, pungent, and sweet were the predominant flavors. They can clear dampness-heat, regulate Qi dynamics to relieve cramps and pain, as well as tonify the deficiency. Along with entering the liver and gallbladder meridians, these herbal medicines also entered the spleen, stomach, and lung meridians to prevent potential disease transmission. The combinatorial medicinal actions of the effective common Chinese herbal medicine highlight the importance of the holistic concept of traditional Chinese medicine when treating CCLGDHS. In addition, the inclusion of activating blood to promote blood circulation, relieving cramps and alleviating pain, and tonifying the spleen and stomach represents a new finding in the treatment principle for CCLGDHS.

This paper presents an effective approach for updating finite element dynamic model from incomplete modal data identified from ambient vibration *** proposed method is based on the relationship between the perturbation of structural parameters such as stiffness and mass changes and the modal data measurements of the tested structure such as measured mode shape *** updating parameters including both stiffness and mass parameters are employed to represent the differences in structural parameters between the finite element model and the associated tested *** updating parameters are then evaluated by an iterative solution procedure,giving optimised solutions in the least squares sense without requiring an optimisation *** order to reduce the influence of modal measurement uncertainty,the truncated singular value decomposition regularization method incorporating the quasi-optimality criterion is employed to produce reliable solutions for the structural updating ***,the numerical investigations of a space frame structure and the practical applications to the Canton Tower benchmark problem demonstrate that the proposed method can correctly update the given finite element model using the incomplete modal data identified from the recorded ambient vibration measurements.

BACKGROUND Majority of adhesive small bowel obstruction(SBO)cases can be managed ***,a proportion of patients failed non-operative *** To evaluate the predictors of successful non-operative management in adhesive *** A retrospective study was performed for all consecutive cases of adhesive SBO from November 2015 to May *** collated included basic demographics,clinical presentation,biochemistry and imaging results and management *** imaging studies were independently analyzed by a radiologist who was blinded to the clinical *** patients were divided into group A operative(including those that failed initial non-operative management)and group B non-operative for *** Of 252 patients were included in the final analysis;group A(n=90)(35.7%)and group B(n=162)(64.3%).There were no differences in the clinical features between both *** tests of inflammatory markers and lactate levels were similar in both *** the imaging findings,the presence of a definitive transition point[odds ratio(OR)=2.67,95%confidence interval(CI):0.98-7.32,P=0.048],presence of free fluid(OR=2.11,95%CI:1.15-3.89,P=0.015)and absence of small bowel faecal signs(OR=1.70,95%CI:1.01-2.88,P=0.047)were predictive of the need of surgical *** patients that received water soluble contrast medium,the evidence of contrast in colon was 3.83 times predictive of successful non-operative management(95%CI:1.79-8.21,P=0.001).CONCLUSION The computed tomography findings can assist clinicians in deciding early surgical intervention in adhesive SBO cases that are unlikely to be successful with non-operative management to prevent associated morbidity and mortality.
