Objective To explore the acupoint selection law for acupoint stimulation to improve gastrointestinal function after colorectal cancer surgery based on data mining technology.Methods Literature about acupoint stimulation to improve gastrointestinal function was retrieved from CNKI,VIP,Wanfang Data,SinoMed,PubMed,Web of Science and Cochrane Library from the establishment of databases to July 1,2023.Data extraction and analysis were performed using Excel 2021.Association rule analysis and clustering analysis were conducted using R language.Results Totally 197 articles were collected,with 242 combinations of acupoints involving 69 acupoints and the total use frequency of acupoints was 878 times.The top 3 acupoints used in frequency were Zusanli(ST36),Shangjuxu(ST37),and Neiguan(PC6).The top 3 involved meridians were the stomach meridian,Conception Vessel,and spleen meridian.The acupoints were mainly distributed in the lower limbs,and the most commonly used intervention method was needle punching.The association analysis discovered a combination of acupoints centered around Zusanli(ST36),which included Shangjuxu(ST37),Neiguan(PC6),and Sanyinjiao(SP6).Clustering analysis identified 4 effective cluster combinations.Conclusion Acupoint stimulation improves gastrointestinal function after colorectal cancer surgery.Multiple acupoint selection ideas are used,and the summarized acupoint selection and compatibility law in this study can provide reference for clinical research and application.

Objective To systemically evaluate the efficacy of all kinds of therapies of cerebral venous sinus thrombosis (CVST) associated with intracranial hematoma (ICH) and provide reference for making treatment scheme.Methods We searched English databases (Pubmed,ISI Web of science and Cochrane library databases) for publications on CVST associated with ICH and the relevant references of those articles.Retrieval time deadline was up to January 2015,and the language was set to English.All publications were searched without restrictions of publication type or published fields.Documents were screened to extract data and to analyze systemically.Results In total,17 articles fulfilled the inclusion criteria and included 31 patients.Because of the severities of reported cases were greatly different and treatments were varied,these patients were divided into 3 levels to get a better understanding of the efficacy.In 6 patients of stage Ⅰ,3 accepted anticoagulation,1 operative treatment,1 endovascular intervention and the left one used more than one methods;the prognosis was good and modified Rankin scale (mRS) score was 0 no matter which kind of therapy was performed.In 11 patients of stage Ⅱ,2 accepted anticoagulation enjoyed mRS scores of 0 and 6,3 operative treatment enjoyed mRS scores of 0,1 and 6,1 endovascular intervention enjoyed mRS scores of 0,and the left 5 used more than one method enjoyed mRS scores of 0,1,1,2 and 2.In 8 patients of stage Ⅲ,1 accepted anticoagulation enjoyed mRS scores of 2,3 operative treatment enjoyed mRS scores of 1,2 and 4,and 4 endovascular intervention enjoyed mRS scores of 0,1,1 and 1.Conclusion It seems that anticoagulation therapy alone may not be effectively enough for those patients that with severe clinical or imaging features;individualized therapy strategies with different types would be more effective.

Objective To explore the application value of three-dimensional (3D) printing in skull base tumor resection.Methods Fourteen patients accepted resection of skull base tumors in our hospital from May 2016 to November 2017 were chosen in our study;before surgery,solid models of the tumors,having bones of the skull base,tumor tissues and main blood supply arteries,were established by 3D printing;resection was simulated in these models and the surgical approaches and surgical methods were determined accordingly.The disease history,preoperative and postoperative imaging data were analyzed retrospectively.Results The mean time for making a solid model of the tumors was 18.5 h,and the cost was about 5,000 Yuan.Postoperative CT and MR imaging showed that total excision was achieved in 8 patients,subtotal excision was achieved in 5 patients,and one with tumor of the jugular foramen achieved total excision of the intracranial tumor and subtotal excision of the extracranial tumor.One patient had large hemispheric infarction after operation and decompressive craniectomy was performed;the other 13 patients recovered well without serious complications or death.Conclusion The 3D printing technique can assist the preoperative simulation and formulation of skull base tumor resection,and improve the efficiency and safety of the operation.
