Objective:To develop the Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with Inflammatory Bowel Disease (IBD), and test its reliability and validity.Methods:Guided by the theory of knowledge, attitude, and practice, a preliminary draft of the scale was formed through literature review, Delphi expert consultation, and pre-survey. From May to August 2022, convenience sampling was used to select 200 IBD patients who visited the Gastroenterology Clinic of three ClassⅢ Grade A comprehensive hospitals in Jiangsu Province as the research subject for a questionnaire survey. The critical ratio method, correlation analysis method, internal consistency method, commonality and factor loadings were used for item analysis of the scale. Exploratory factor analysis, content validity index, and internal consistency reliability were applied to test the reliability and validity of the scale.Results:A total of 200 questionnaires were distributed, and 181 valid questionnaires were collected, with an effective response rate of 90.50% (181/200). The Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with IBD included three dimensions of knowledge, attitude and practice, with a total of 21 items. The content validity index at the scale level was 0.917, and the content validity index at the item level ranged from 0.833 to 1.000. Exploratory factor analysis extracted three common factors, with a cumulative variance contribution rate of 74.197%. The Cronbach's α coefficient of the total scale was 0.951, and the coefficients of each dimension were 0.914 to 0.942. The test-retest reliability coefficient of the total scale was 0.918, and the test-retest reliability coefficients of each dimension ranged from 0.737 to 0.833.Conclusions:The Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with IBD has good reliability and validity, which can help medical and nursing staff evaluate patients' understanding and acceptance of microbial transplantation, so as to provide a basis for personalized communication in shared decision making between doctors and patients.

Objective To analyze the epidemic characteristics of varicella and the genetic characteristics of varicella zoster virus (VZV) in Yangzhou in 2021, and to provide a theoretical basis for the scientific prevention and control of varicella in Yangzhou. Methods Descriptive epidemiological analysis was carried out on the varicella outbreaks reported in Yangzhou in 2021. Throat swabs or herpes fluid samples from varicella cases in 2021 were collected, and the viral nucleic acid was detected by real-time fluorescent quantitative PCR. The genotype and evolutionary relationship of the virus strain were determined according to the 6 SNPs in the ORF22 gene fragment sequence. Results In 2021, there were 20 varicella outbreaks in Yangzhou, involving 147 cases, all of which occurred in kindergartens and primary and secondary schools, and the peak incidence was in the age group of 4-7 years old. The high incidence time of the outbreaks was from May to July, and from November to January of the next year. The varicella vaccination rate of the cases was low, and all were 1-dose vaccination. The gene sequencing results of 8 samples were J/clade 2, and 3 of them had A-C synonymous mutation at position 37997 in ORF22 sequence. Conclusion In 2021, varicella outbreaks in Yangzhou occurred mainly in kindergartens and schools. Preschool children are susceptible, all of which are caused by J/clade 2 varicella-zoster virus. It is suggested to strengthen the monitoring and management of the varicella epidemic situation in schools in the city, and at the same time incorporate the varicella vaccine into the routine immunization program of the city and strengthen 2 doses of varicella vaccination.

The article reports a rare case of isolated persistent left superior vena cava (PLSVC) found during the catheterization of a dialysis catheter in an end-stage renal disease patient and the occurrence of guidewire entrapment in Chiari net. The patient was scheduled to have emergency dialysis due to end-stage renal disease and acute left heart failure. And a tunnel-cuffed catheter (TCC) for dialysis insertion was planned. Isolated PLSVC was found firstly by the imaging process. Then the guidewire was entrapped at the right atrium in the further operation. During the operation of the guidewire, the guidewire loosened and withdrawn with a fine fiber, which was considered a possibility of Chiari net. In the follow-up after one week, the TCC worked well, and the heart function improved after dialysis.

Objective:To analyze the clinical and pathological characteristics, treatment and prognosis of renal changes in patients with Kimura disease and improve the clinicians′ understanding on renal manifestations of Kimura disease.Methods:The clinical data of Kimura disease patients with definite diagnosis and detailed data in Peking Union Medical College Hospital from January 1980 to August 2020 were retrospectively analyzed. The patients were divided into renal impairment group and non-renal impairment group according to whether the kidney was involved or not and the related clinical data between the two groups were compared. The patients presenting with nephrotic syndrome were followed up.Results:There were 60 patients with Kimura disease confirmed by pathological diagnosis with 48 males. The median age was 33(3, 62) years old, and the median duration was 36(12, 111) months. There were 18 cases complicated with renal injury in 49 patients with complete routine urine and renal function examination and the main manifestations of renal injury were proteinuria and/or microscopic hematuria. There was no significant difference at age, sex and absolute value of eosinophils between the two groups (all P>0.05). Compared with the renal inpairment group, patients in non-renal inpairment group had longer course of disease, higher levels of hypersensitive C-reactive protein and erythrocyte sedimentation rate, and lower median values of total eosinophils and total IgE, but there was no statistically significant difference (all P>0.05). Among the patients with renal involvement, 6 patients met the diagnostic criteria for nephrotic syndrome, and 5 of them completed renal biopsies. The renal pathological diagnosis was membranous nephropathy in 2 cases and minimal change disease in 3 cases, and no interstitial eosinophil infiltration was found in renal biopsy tissues. These patients had a good response to glucocorticoids and/or immunosuppressive therapy, and achieved complete remission of nephrotic syndrome; at the same time, lymphadenopathy caused by Kimura disease could be well controlled. Conclusions:Kimura disease can combine with various renal lesions, and the pathology of nephrotic syndrome can be membranous nephropathy or minimal change nephropathy. After energetic treatment of glucocorticoids and/or immunosuppressive therapy, nephrotic syndrome can be completely relieved, and lymphadenopathy can be well controlled. The relationship between Kimura disease and renal disease needs further study.

Two patients with Gitelman syndrome were admitted to the Department of Endocrinology, Third Xiangya Hospital of Central South University. The genomic DNA from the patients' peripheral blood was extracted and the whole-exome sequencing was performed to detect the possible mutations. The function of the mutation sites was analyzed by bioinformatics software. Through whole-exome sequencing and Sanger sequencing, we have found that 2 patients with Gitelman syndrome carried compound heterozygous mutations of SLC12A3 gene, which were c.486_490delTACGGinsA, p.R943W, p.D486N, and p.R928C. Among them, c.486_490delTACGGinsA insertion deletion mutation causes frame shift and protein truncation. The p.R943W, p.D486N, and p.R928C of SLC12A3 gene were predicted to be pathogenic mutations by SIFT, PolyPhen2, and Mutation Taster. These 4 mutations were all reported, but p.R943W was first reported in Chinese population. Gitelman syndrome is rare in clinic and the rate of missed diagnosis is high. Early genetic analysis in patients with Gitelman syndrome is helpful to determine the etiology and guide the treatment.

Objective:To analysis effectiveness of the "14 plus 7 day quarantine" and "nucleic acid plus total antibody testing" strategy (combined screening strategy) for screenin the imported patients with COVID-19 in Xiamen.Methods:The study populations were overseas travelers arriving in Xiamen from March 17 to December 31, 2020, and overseas travelers who had quarantine outside Xiamen for less than 21 days from July 18 to December 31, 2020. Data were collected and analyzed on the timing of detection, pathways, and test results of the imported patients with COVID-19 after implementing combined screening strategy.Results:A total of 304 imported patients with COVID-19 were found from 174 628 overseas travelers and 943 overseas travelers from other cities. A total of 163 cases (53.6%) were diagnosed by multitime, multisite intensive nucleic acid testing after positive finding in total antibody testing. Among them, 27 (8.9%) were first positive for nucleic acid in 14 plus 7 day quarantine and 136 were first positive for nucleic acid in 14-day quarantine. Only 8 of these individuals were tested positive for nucleic acid after positive total antibody testing. The other 128 individuals were tested positive for nucleic acid after being negative for average 2.3 times (maximum of 6 times). Aditional 155 cases might be detected by using the combined "14 plus 7 day quarantine" and " nucleic acid plus total antibody testing" strategy compared with "14-day quarantine and nucleic acid testing" strategy, accounting for 51.0% of the total inbound infections. So the combined screening strategy doubled the detection rate for imported patients with COVID-19. No second-generation case caused by overseas travelers had been reported in Xiamen as of February 26, 2021.Conclusions:Xiamen's combined screening strategy can effectively screen the imported patients with COVID-19 who were first positive for nucleic acid after 14 day quarantine. Compared with "14 day quarantine and nucleic acid testing", the combined screening strategy improved detection rate and further reduced the risk of the secondary transmission caused by the imported patients with COVID-19.

To construct and develop the home self-sampling processes of cervical human papillomavirus (HPV) detection and evaluate its application effect. An integrated HPV self-sampling detection platform is scheduled to include three terminals: a user terminal, a detection terminal and a medical terminal. It covers a wide range of functions of self-sampling kit acquisition of user, sample logistics tracking, inspection services, report query, medical consultation, health management, and follow-up tracking. A total of 8 053 users applied for self-sampling kits and all completed online user information registration from January to November 2020. The average age of users ranged from 17 to 84 with a median age of 42 years old. Registered users of the platform were distributed in Jiangsu, Jiangxi, Hebei, Shanxi, Shanghai, Ningxia, Anhui, Zhejiang, Inner Mongolia, Beijing and Xinjiang. 8 045 users completed self-sampling with a kit return rate of 99.9%. Six users lost the kits during the express delivery, and 2 users had the kits contaminated due to improper application; The amount of exfoliated cells collected from 8 045 cases in the sample kits were all within the endogenous internal standard of the nucleic acid kit, and the qualified rate of kits was 100%. The proportion of test report issued by the detection platform within 3 d accounts for 96.93% (7 799/8 054). Among the 763 positive users, 742 completed 6-month reexamination, with a reexamination rate of 97.25%. Unfortunately, 21 cases were lost to follow-up. Taken together, HPV home-based self-sampling is simple, convenient and efficient in use. It can expand the coverage of cervical cancer screening and may help promote HPV screening.

OBJECTIVE: To evaluate the effect of standardized health education on the sputum specimen collection rate for nucleic acid detection of coronavirus disease 2019 (COVID-19). METHODS: Two hundred and twenty-seven patients in fever clinics and isolation wards of Sir Run Run Shaw Hospital of Zhejiang University and 307 migrant workers returning to 5 enterprises in Shanghai from February 3 to March 14, 2020 were enrolled in the study. Through clarifying the procedures of collecting sputum specimens, making graphic/video health education materials, standardizing the contents and methods of health education, we conducted education to the subjects. The subject expectorated spontaneously or with medical assistance. For patients, the number of sampling attempts and sputum acquisition times were documented before and after the implementation of the standardized expectoration method; for the returning migrant employees in the enterprises, only the number of collected samples after the implementation of the standardized expectoration method were recorded. RESULTS: A total of 378 sputum samples were collected from 227 patients. The sputum sampling rates before and after the implementation of health education were 40.9%and 58.4%, respectively ( CONCLUSIONS The education for standardized sputum sample collection method can effectively increase the sputum collection rate.
