Objective With the goal of improving the patient experience of intravitreal injection,the diagnosis and treatment process is optimized and the waiting time is shortened.Methods In the medical records of patients who underwent intravitreal injection,the medical records of patients in the same period before and after the optimization of the process were extracted by systematic sampling method as the observation group(n=336)and the control group(n=150).The data of medical quality,medical efficiency and waiting time of patients were compared between the two groups.Results After the optimization a of the process,the appointment time of intravitreal injection surgery decreased from(67.77±29.95)h to(10.66±5.69)h,the time in hospital on the operation day decreased from(4.52±0.94)h to(2.55±0.67)h,the preoperative examination time decreased from(14.34±6.49)h to(5.19±1.60)h,and the number of surgeries per doctor half day owerage increased from(37.88±10.94)to(47.50±4.77),the difference was statistically significant(P＜0.01).There was no significant difference in the incidence of secondary glaucoma and endophthalmitis between the two groups(P＞0.05).Conclusion The process optimization of the intravitreal injection center around the patient experience has significantly reduced the waiting time and improved the patient experience.

Improving the entire outpatient clinic experience is an important measure in the new era to enhance patients'sense of gain from medical treatment.Beijing Tongren Hospital Affiliated to Capital Medical University explores the establishment of a full-process outpatient service management system based on continuous improvement of medical services.Through the concept of forward service,it focuses on the patient's pre-diagnosis experience;the process is simplified and intelligently guided to optimize the patient's in-diagnosis experience;and continuous diagnosis and treatment Model innovation improves patients'post-diagnosis experience and creates a Chinese-style modern outpatient medical service model to continuously meet the people's growing needs for a better life.

Objective To investigate the clinical manifestations,molecular genetics and gonadal pathol-ogy characteristics of patients with disorders of sex development(DSD),and to summarize the clinical experi-ence of identifying rare diseases from common symptoms.Methods The clinical data of 416 patients with DSD diagnosed and treated in the multidisciplinary center of DSD of Guangzhou Women and Children's Medical Cen-ter from May 2018 to August 2023 were retrospectively analyzed,summarized and discussed.Results Accord-ing to chromosome karyotype,416 cases of DSD were classified into three types:92 cases(22.1％)of abnormal sex chromosome karyotype,285 cases(68.5％)of 46,XY karyotype and 39 cases(9.4％)of 46,XX karyotype.Among the 92 patients with abnormal sex chromosome karyotype,59 cases were raised as males,18 cases(30.5％)complained of short penis with hypospadias and cryptorchidism.The most common karyotype was 45,X/46,XY(58 cases,63.0％).Among the 285 patients with 46,XY karyotype,238 cases were raised as males,and 63 cases(26.5％)complained of short penis and hypospadias;47 cases were raised as females,and 13 ca-ses(27.7％)complained of inguinal mass.A total of 216 patients with 46,XY karyotype were subjected to whole exome gene detection,and 155 cases(71.8％)were found to have molecular pathogenesis with the clinical phe-notype.Among the 39 patients with 46,XX karyotype,19 cases were raised as males,and 8 cases(42.1％)com-plained of short penis and hypospadias.In the 18 cases of gonad biopsy,17 cases showed testicular tissue in go-nads.Whole exome sequencing was performed in 14 cases.NR5A1 gene heterozygous mutation,SRY gene muta-tion and SOX3 gene mutation were found in 2 cases,respectively(14.3％).Twenty cases were raised as females,and 14 cases(70.0％)complained of clitoral hypertrophy.Gonad biopsy was performed in 8 cases,with 7 cases of ovotestis(87.5％)and 1 case of NR5A1 gene heterozygous mutation(14.3％).Conclusions The etiologies of DSD are complex and diverse,and the clinical manifestations are various,which can be manifested as hypospa-dias,micropenis,cryptorchidism and other common symptoms of the urinary system.Different etiologies have dif-ferent treatment options.Therefore,chromosome karyotype,molecular genetic testing and gonadal pathology can be used to clarify the cause of disease,especially for rare diseases,improve the detection rate,reduce the rate of missed diagnosis,and ensure reasonable treatment,especially sex selection.

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.
