3.Research advances of precision treatment for pancreatic cancer
Chinese Journal of Digestive Surgery 2021;20(4):385-394
Pancreatic cancer is the third leading cause of cancer-related death in the world due to its high malignancy, difficult in early diagnosis, poor treatment efficacy, and high mortality. In recent years, benefiting from the progress of combined chemotherapy and neoadjuvant therapy, the prognosis of patients with pancreatic cancer has been improved to a certain extent. However, compared with other tumors, progress of precision medicine in pancreatic cancer is slow. The authors introduce the latest progress and difficulties in precision medicine of pancreatic cancer including molecular classification based on single gene and omics, monitoring tumor progression and guide treatment by minimally invasive liquid biopsy, as well as targeting therapy and immuno-therapy, in order to accelerate the development of precision medicine of pancreatic cancer.

AIM: To study the infiltration of polymorphonuclear neutrophils ( PMNs ) after conjunctival flap covering in alkali-burned cornea.
●METHODS: Rabbit cornea alkali-burned model was made, then 50 rabbits were randomly divided into the experimental group ( n=25 ) and the control group ( n=25 ) . At the same time the surgery of conjunctival flap covering was given to rabbits of the experimental group. The condition developing of alkali-burned cornea was observed by slit lamp biomicroscopy, and took photos in two groups. The infiltration of PMNs was identified by hematoxylin eosin ( HE) staining in different periods.
●RESULTS:The quantity of PMNs increased on the 3d, reached the lower level on 7d, shown a peak on the 14d, then decreased gradually. PMNs level of the experimental group was significantly lower than that in the control group, and the difference of 3, 14 and 21d was significant (P<0. 05).
●CONCLUSION: During the wound healing process, alkali - burned cornea has close relation with the infiltration of PMNs. The treatment of conjunctival flap covering for the severe alkali-burned cornea was found to have good effect.

This study analyzed the current clinical terminology standardization, systematization research status of traditional Chinese medicine(TCM). The previous version of the TCM clinical term system had some problems including imperfect classification structure, unclear relationship between concepts and so on, which made the TCM clinical terminology system(TCMCTS) difficult to support the clinical practice of TCM. The suggestions for system improvement were using ontology method to build TCMCTS concept model bases on the previous researches and data extracted from TCM clinical electronic medical record, and top-level-ontology accordance with ISO standards. The study also tried to summarize the ‘semantic network between classes’ through semantic relationships.

Objective To investigate the thermal effects on tissue structures during microwave endometrial ablation(MEA)and seek a feasible method of endometrial thinning and a fitting mode of applicator radiating microwaves.Methods Operations were performed between the group of thorough uterine curettage and the group of early follicular phase in in vitro or in vivo uterus.The former was treated with MEA after thorough uterine curettage;while the latter was treated with MEA in the early follicular phase directly.The applicator radiating microwaves were moved in "Z" or "Z+W" shape inside uterine cavity.At the same time the serosal temperature was measured in the uterine fundus,tael cornua uteri,the posterior wall and the lower part of anterior wall.After operations the uterine specimens were stained by hematoxylin- eosin,and respiratory enzyme dehydronicotinamide adenine dinucleotide phosphate diaphorase(NADH-d) methods.The morphologic changes and the depth of tissue thermal damage were evaluated using an optical microscope and electron microscope.Results(1)Under the optical microscope the endometrial glands became distorted,the cell boundaries disappeared,the nucleoli turned condensed and were stained darker. A large number of acute inflammatory cells appeared in fibrous tissue.In the shallow muscle layer cells were arrayed thickly,nucleoli were solidified and condensed,and cellular plasm were concentrated.The endometrial and the superficial muscle layers were damaged and colorless with NADH-d staining.The scope of the tissue thermal damage was clearly seen.Under an electron microscope,some smooth muscle ceils, chromatin,karyotheca and cellular membranes were destroyed.The mitochondria were swollen,membranes were ruptured,and the crista disappeared.Many organelles were destroyed.The chromatin was lightly wrecked in the transitional area between putrescence and the normal smooth muscle tissue.Karyotheca and cellular plasm still existed,the mitochondria were highly edematous and the crista were disappeared,and the granular endoplasmic reticula were slightly expanded and degranulated.(2)The serosal temperature in in vitro uterus was significantly higher than that in in vivo uterus(P0.05).The injury depth of the "Z+ W" radiation group increased significantly than that of the " Z" radiation group(P
