Objective To observe the effect of Weipixiao, a compound recipe which has the actions of strengthening spleen, resolving stasis and removing toxins, on the histopathological changes of gastric mucosal tissue in rats with gastric precancerous lesions ( GPL) . Methods SD rats were randomly divided into normal group, model group, Vitacoenzyme group (0.2 g·kg-1·d-1), and high-, middle-, and low-dose Weipixiao groups ( in the dose of 15, 7.5, 3.75 g·kg-1·d-1, respectively) . Except for the normal control group, the rats in other groups received spontaneous intake of N-methyl-N’-nitro-nitrosoguanidine ( MNNG) solution combined with irregular diet and oral use of purgative herbs for 18 weeks to induce GPL. From the 9th week, the mediation groups were simultaneously given corresponding medicine for 10 weeks. At the end of the experiment, the histopathological changes of gastric mucosal tissue in all groups were observed. Results Pathological scores of intestinal metaplasia and epithelial dysplasia in rat gastric mucosa of the model group were significantly increased ( P<0.01 compared with those of the normal group) , but were decreased in three Weipixiao groups to various degrees, particularly in low-dose Weipixiao group ( P<0.05 or P<0.01) . Conclusion Weipixiao can block and reverse gastric intestinal metaplasia and dysplasia in GPL rats to certain degrees, and low-dose Weipixiao may have better long-term effect for the prevention and treatment of GPL.

Objective:To explore the surgical method and clinical effect of forearm arterialized venous flap in repair of soft tissue defects of fingers.Methods:A total of 13 cases of finger soft tissue defects with exposure of deep tissue were repaired with forearm arterialized venous flap from January, 2013 to October, 2019. The flap was designed in the forearm, and 2 parallel superficial veins were selected, the diameter of vein was similar to that at recipient site. The long axis of the flap was the same as that of the vein, and the width of the flap was divided into 3 equal parts by the 2 superficial veins. The free flap was cut longitudinally in the middle between 2 vessels under microscope, and a width of about 2 mm of the subcutaneous tissue was removed to the subdermal vascular network. The communicating branch between 2 vessels was ligated, and the subcutaneous tissue between 2 vessels was cut completely. The flap was not inverted, and the cut area was 3.5 cm× 2.5 cm-7.0 cm×4.0 cm. The proximal ends of the 2 vessels in the flap were anastomosed with the arteries and veins of the recipient area.Results:Thirteen flaps survived, and 9 patient entered follow-up for an average of 11(3-23) months. The flaps were soft and had no effect on the joint movement, slightly bloated. The TPD of flaps was 9 - 18 mm, with an average of 13 mm.Conclusion:Forearm arterialized venous flap has the advantages of high survival rate, satisfactory function, finger pulp-type change, superficial location, easy harvest and no sacrifice of main artery. It is an ideal method for repairing finger soft tissue defects.

At present, implant surgery robots have basically achieved "surgical intelligence", but "brain-inspired intelligence" of robots is still in the stage of theory and exploration. The formulation of a clinical implantation plan depends on the timing of implantation, implantation area, bone condition, surgical procedure, patient factors, etc., which need to evaluate the corresponding clinical decision indicators and clinical pathways. Inspired by evidence-based medicine and the potential of big data and deep learning, combined with the data characteristics of clinical decision indicators and clinical pathways that can be quantitatively or qualitatively analyzed, this review simulates the cognitive behavior and neural mechanisms of the human brain and proposes a feasible brain-inspired intelligence scheme by predicting the decision indices and executing clinical pathways intelligently, that is, "select clinical indicators and clarify clinical pathways -- construct database -- use deep learning to intelligently predict decision indicators -- intelligent execution of clinical pathways -- brain-inspired intelligence of implant decision-making". Combined with the previous research results of our team, this review also describes the process of realization of brain-inspired intelligence for immediate implant timing decisions, providing an example of the comprehensive realization of brain-inspired intelligence of implant surgery robots in the future. In the future, how to excavate and summarize other clinical decision factors and select the best way to realize the automatic prediction of evidence-based clinical indicators and pathways and finally realize the complete intellectualization of clinical diagnosis and treatment processes will be one of the directions that dental clinicians need to strive for.
