OBJECTIVE To investigate the mechanism of inhibition of breast cancer lung metastasis by Shugan Yishen Recipe by studying the effects of Shugan Yishen Recipe(SGYSR)on gene expression in the lung microenvironment of mice with breast cancer.METHODS A high metastasis model of breast cancer was constructed,and the mice were randomly divided into saline group,low,medium,high(0.5,1,2 g·kg-1)Shugan Yishen Recipe groups,and docetaxel group(5 mg·kg-1),and intervened for 28 days.HE staining was used to observe the lung tissue structure;transcriptome analysis was performed on the metastatic foci,and the key differential gene expression was screened by bioinformatics analysis of the GO and KEGG pathway characteristics of the gene ex-pression profiles,and the expression of key immune genes was analyzed by qPCR and Western blot.The expression of MDSCs was de-tected by flow cytometry;the expression of cytokines and chemokines including Cxcl2,and GM-CSF was detected by ELISA.RE-SULTS Compared with the saline group,the number of metastatic nodules in lung tissues of the middle and high dose groups of Shu-gan Yishen Recipe and docetaxel group were correspondingly lower;HE staining suggested that the degree of lung pathology was im-proved.There were 814 differentially expressed genes in the lung microenvironment of the high-dose group of Shugan Yishen Recipe and the saline group,of which 713 genes were down-regulated and 101 genes were up-regulated;screening for key inflammatory medi-ator genes in the Shugan Yishen Recipe group,Nfkbiz,Tnfaip3,Maff,Hspa1a,Hspb1 and Cxcl2,the inflammatory genes in the Shu-gan Yishen Recipe,as compared with that of the saline group,were significantly down-regulated(P<0.05,P<0.01),and ultimately its results were consistent with the trend of the transcriptome results.Western blot was used to verify the results at the protein level,and it was found that compared with the saline group,the protein expression levels of Nfkbiz,Tnfaip3,Maff,Hspa1a and Cxcl2 in the Shugan Yishen Recipe group were decreased(P<0.05,P<0.01),while the protein expression of Hspb1 was up-regulated(P<0.01).Both the Shugan Yishen Recipe group and the docetaxel group could inhibit the expression of MDSCs(P<0.001),and the ex-pression of Cxcl2,and GM-CSF decreased to a certain extent(P<0.05,P<0.01).CONCLUSION Shugan Yishen Recipe can in-hibit breast cancer lung metastasis and regulate the lung immune microenvironment genes in a wide range.

With the continuous development of digital technology, three-dimensional (3D) facial scanning technology is becoming more and more widely used in dentistry, where it enhances the precision of various processes of clinical diagnosis and treatment, and provides new perspectives and tools for dental research and application. Nowadays, 3D facial scanning technology meets clinical needs in terms of accuracy, and most facial scanners have an accuracy of 140-1 330 μm, and the 3D facial scanning related applications of smartphones can also meet the clinical application needs to a certain extent. In the clinical field, the 3D scanner can be combined with a variety of technologies to achieve multi-modal data fusion and create virtual patients, and its prediction rate in obstructive sleep apnea hypopnea syndrome is as high as 91%, which has great clinical application value. This article aims to explore the research status, clinical applications, and accuracy analysis of 3D facial scanning techniques in the field of dentistry.

Objective To observe the clinical efficacy of shugan yishen recipe in the treatment of postmenopausal estrogen receptor-positive breast cancer patients during endocrine therapy.Methods A total of 110 postmenopausal breast cancer patients undergoing aro-matase inhibitor endocrine therapy at Shanghai Municipal Hospital of Traditional Chinese Medicine from July 2021 to September 2023 were divided into observation group and control group by random number table method,with 55 patients in each group..Both groups received standard treatment;the observation group also took shugan yishen recipe,while the control group also took shugan yishen recipe placebo,treatment for 12 weeks.The clinical efficacy,traditional Chinese medicine syndrome scores,bone metabolism,tumor markers,T-cell subsets(CD4+,CD8+,CD4+/CD8+)of the two groups were observed,and the safety was evaluated.Results A total of 106 patients completed the experiment,with 53 patients in each group.After treatment,the total clinical effective rate was 75.5％in the observation group,and 58.5％in the control group,the clinical effect of the observation group was better than that of the control group(P＜0.01).Compared with before treatment,TCM syndrome scores in both groups were decreased(P＜0.01).After treatment,β-c-terminal te-lopeptide of type-Ⅰ collagen(β-CTX),carbohydrate antigen 125(CA125),carbohydrate antigen 153(CA153)and CD8+were all decreased compared with those before treatment(P＜0.05);N-mid osteocalcin(N-MID),CD4+,CD4+/CD8+were higher than those before treatment(P＜0.01).After treatment,β-CTX,N-MID,CA153,CD8+and CD4+/CD8+in the observation group were significantly better than those in the control group(P＜0.01).Conclusion Shugan yishen recipe can improve bone metabolism abnor-malities caused by endocrine treatment in postmenopausal patients with estrogen receptor-positive breast cancer,reduce serum tumor marker levels,enhance immune function of patients,and is safe and effective.

The current treatment strategy for rectal cancer is a comprehensive treatment centered on surgery. The application of total mesorectal excision (TME) has significantly reduced the local recurrence rate and improved the survival prognosis, but a series of pelvic organ dysfunction caused by pelvic autonomic nerve injury during the operation will reduce the postoperative quality of life of patients. Pelvic autonomic nerve preserving (PANP) radical proctectomy has emerged, but the biggest challenge in the implementation process of this technology is the accurate identification of nerves. A series of studies have shown that pelvic intraoperative autonomic monitoring (pIONM) can effectively assist surgeons to identify nerves, The purpose of this article is to introduce the function of pelvic autonomic nerve, the clinical manifestation of postoperative pelvic dysfunction and its relationship with nerve injury, the key points of implementing PANP, and the current situation and research progress of pIONM technology application.

Objective To evaluate the long-term effect of surgical procedures for congenital choledochal cyst (CCC).Methods From 1986 to 2000, 120 cases of CCC were admitted and 73 of them underwent the primary operations in General Hospital of PLA. Three types procedures were performed,type I: external drainage of CCC in 7 cases; type II:cystojejunal Roux-en-Y anastomosis in 5 cases; type III: cyst excision with cystojejunal Roux-en-Y anastomosis or cystoduodenostomy in 57cases,and other procedures in 4 cases.Results 68 cases were followed-up for 6 months to 5 years (median 2.7 years). Three cases undergoing type I operations accepted reoperations;two cases undergoing type II operations accepted reoperations due to severe complications as cholongitis and hepatolithiasis; 57 cases treated by type III operation with the good results 88.7% and none reoperation.Conclusions External drainage is only a first-aid management on emergency basis. Internal drainage should never be done,because the effect is temporary,and severe complications result in reoperations. Cyst excision with biliary tract reconstruction is recommended as the optimal treatment of CCC.
