The primary importance of magnetic resonance (MR) imaging in evaluating anal fistulas lies in its ability to demonstrate hidden areas of sepsis and secondary extensions in patients with fistula in ano. MR imaging is relatively expensive, so there are many healthcare systems worldwide where access to MR imaging remains restricted. Until recently, computed tomography (CT) has played a limited role in imaging fistula in ano, largely owing to its poor resolution of soft tissue. In this article, the different imaging features of the CT and MRI are compared to demonstrate the relative accuracy of CT fistulography for the preoperative assessment of fistula in ano. CT fistulography and MR imaging have their own advantages for preoperative evaluation of perianal fistula, and can be applied to complement one another when necessary.

Objective: To compare the effectiveness and clinical safety between the two through the observation of Orthokeratology lens and multifocal soft lens. Methods: By using prospective longitudinal design, sixty patients (120 eyes) with orthokeratology lens and multifocal soft lens were selected. After 1, 3, 6 and 12 months, our tests were conducted, including ocular surface disease index (OSDI) questionnaire, tear break up time(BUT), corneal fluerescein staining (CSF) and meibomian gland function assessment, before and after wearing glasses, ocular axis and refraction in 6,12 and 18 months after were evaluated to assess the effect of myopia control. Results: But in the orthokeratology lens group was lower than the soft lens group after two months. The difference was statistically significant( t=4.35, P <0.05). After 1 month of wearing glasses, BUT in the orthokeratologylens group was shorter than before( F=305.83, P <0.05). In the group of soft lens, there was no statistically significance before and after wearing glasses( F= 0.38, P >0.05). There was no difference in corneal fluorescence staining (CSF) and meibomian gland function between the two groups before and after wearing glasses.( F time=1.55, 1.38, 10.15, 1.50, P >0.05, F group=2.31, 0.02， P >0.05). After 18 months of wearing orthokeratology lens, the average degree of spherical lens increased by -0.53 D, which was different from that before wearing( F=6.54, P <0.05). After wearing soft lens 18 month, the average degree of spherical lens increase by -0.34 D, which was different from that before wearing( F=2.88, P <0.05). After 18 months of wearing glasses, there were differences in the growth of ocular axis between the two groups( F =2.73, 2.83, P <0.05). Conclusion Orthokeratology lens and multifocal soft lens are both safe and effective measures to control myopia.

Objective:To observe and determine the gene mutation site and clinical phenotype of a NDP gene mutant family, and provide a basis for the prenatal diagnosis of offspring. Methods:A pedigree investigation study. Two patients and 6 family members of a third-generation Han family with NDP gene mutation who were admitted to the Maternal and Child Health Hospital of Gansu Province from July 2019 to December 2021 were included in the study. The patients and their parents underwent the examination of pupil light reflex, strip light imaging, visual acuity evaluation, fundus color photography, and wide-field fluorescein fundus angiography (FFA). Peripheral blood of all the subjects was collected, the pathogenic genes were screened by whole exome sequencing, and NDP genes were detected by amplification of multiple ligated probes. DNA prenatal diagnosis was performed by amniocentesis at 19th weeks of the mother's third gestation. Results:Proband (Ⅲ1), male, 4 years old, full term natural delivery. At about 40 days after birth, B-mode ultrasonography indicated total retinal detachment in both eyes. Normal hearing and intelligence. Fundus examination was not performed. First sibling of proband (Ⅲ2, big younger brother), ophthalmologic examination 30 days after birth, retinal detachment in both eyes. Proband's mother (Ⅱ2) had unvascularized peripheral temporal retina in both eyes. Wide-angle FFA examination showed no vascularization of the peripheral temporal retina in both eyes, and slight leakage of peripheral vascular fluorescein. The proband's second sibling (Ⅲ3, little younger brother) was screened for neonatal eye disease 1 day after birth. No abnormalities were observed outside both eyes. Cornea and lens transparent. No abnormalities were observed in the optic disc and macula in both eyes. No vascular curvature was observed in the peripheral retina. The results of gene detection showed that there was hemizygote deletion in exon 2 of NDP gene of the proband (Ⅲ1) and its big younger brother (Ⅲ2). His mother (Ⅱ2) had heterozygosity deletion in exon 2 of NDP gene. The phenotype and genetic test results of the proband's father (Ⅱ1), uncle (Ⅱ3), maternal grandfather (Ⅰ1) and maternal grandmother (Ⅰ2) were not abnormal. Conclusions:The hemizygote deletion in exon 2 of NDP gene is a pathogenic variation in the native family. The clinical phenotypes of different genders are different. Prenatal diagnosis is an effective way to block hereditary diseases in families.

PURPOSE: Breast cancer is the most commonly occurring cancer among women worldwide, and therefore, improved approaches for its early detection are urgently needed. As microRNAs (miRNAs) are increasingly recognized as critical regulators in tumorigenesis and possess excellent stability in plasma, this study focused on using miRNAs to develop a method for identifying noninvasive biomarkers. METHODS: To discover critical candidates, differential expression analysis was performed on tissue-originated miRNA profiles of 409 early breast cancer patients and 87 healthy controls from The Cancer Genome Atlas database. We selected candidates from the differentially expressed miRNAs and then evaluated every possible molecular signature formed by the candidates. The best signature was validated in independent serum samples from 113 early breast cancer patients and 47 healthy controls using reverse transcription quantitative real-time polymerase chain reaction. RESULTS: The miRNA candidates in our method were revealed to be associated with breast cancer according to previous studies and showed potential as useful biomarkers. When validated in independent serum samples, the area under curve of the final miRNA signature (miR-21-3p, miR-21-5p, and miR-99a-5p) was 0.895. Diagnostic sensitivity and specificity were 97.9% and 73.5%, respectively. CONCLUSION: The present study established a novel and effective method to identify biomarkers for early breast cancer. And the method, is also suitable for other cancer types. Furthermore, a combination of three miRNAs was identified as a prospective biomarker for breast cancer early detection.

Objective To evaluate computed tomography venography (CTV) in diagnosis of iliac vein stenosis or occlusion.Methods From Jun 2015 to Jun 2017,168 CVD patients with CEAP clinically graded at 4 to 6 underwent evaluation with digital subtraction angiography (DSA) CTV and colour Doppler ultrasound.Taking DSA as standard,the diagnostic value of CTV and colour Doppler ultrasound were analyzed and compared.Results DSA established diagnosis of 95 cases,compared with DSA,CTV's and colour Doppler ultrasound's sensitivity,specificity,positive likelihood ratio and negative likelihood ratio was 87.4％ and 64.2％,94.5％ and 98.6％,15.89 and 45.86 and 0.13 and 0.36.Compared with colour Doppler ultrasound,CTV's sensitivity was significantly higher (P ＜ 0.05,the 95 ％ confidence intervals were 0.764-14.257),and there was no significant difference between them in aspect of specificity (P =0.375,the 95％ confidence intervals were 0.943-0.986),Kappa value was 0.809(P ＜0.05,the 95％ confidence intervals were 0.714-0.893),0.597 (P ＜ 0.05,the 95％ confidence intervals were 0.464-0.717).Conclusion In the diagnosis of CVD combined with iliac and femoral venous stenosis,CTV has outstanding sensitivity,specificity,and good conformancy with that of DSA.

Objective To explore the predictive value of the expression of CD44v6 and EGFR on the efficacy of neoadjuvant chemotherapy (NACT) in stageⅡ-Ⅲ cervical cancer. Methods A total of 53 patients with stageⅡ-Ⅲ cervical cancer diagnosed by pathology were selected. All patients received two cycles of paclitaxel+platinum NACT. The pathological tissue samples of cervical tumors before NACT treatment were collected. The expression of CD44v6 and EGFR were detected by the immunohistochemical SP method, and we analyzed their predictive value of NACT in stageⅡ-Ⅲ cervical cancer. Results Among the 53 patients, 38 were in the NACT effective group (CR+PR), and 15 were in the NACT ineffective group (SD+PD). The expression of CD44v6 in the ineffective group was significantly higher than that in the effective group (P < 0.05). The expression of CD44v6 was significantly different in patients with CR, PR, and SD (P < 0.05). The AUC of CD44v6 to NACT effect on stage Ⅱ-Ⅲ cervical cancer was 0.74 (P < 0.05). The patients in the high expression group of CD44v6 had worse efficacy in NACT than those in the low expression group of CD44v6 (P < 0.05). Pearson test showed that CD44v6 and EGFR expression were correlated (R=0.34, P < 0.05). Conclusion High expression of CD44v6 may reduce the efficacy of NACT in stageⅡ-Ⅲ cervical cancer, suggesting that the expression of CD44v6 has a certain predictive value and clinical significance in the efficacy of paclitaxel+platinum NACT on cervical cancer. Moreover, CD44v6 is positively correlated with EGFR expression.

Objective To collect the serum samples of patients with nonalcoholic fatty liver disease (NAFLD), and to investigate the changes in serum metabolic biomarkers before and after lifestyle intervention. Methods A total of 23 patients who were diagnosed with NAFLD in Department of Gastroenterology and Inpatient Department, Putuo District Central Hospital of Shanghai, from January 2019 to January 2020 were enrolled, and all patients received the intervention with aerobic exercise and equicaloric low-carbohydrate high-protein diet. A total of 13 healthy volunteers who underwent physical examination in Physical Examination Center were enrolled as control group. For the patients with NAFLD, basic information was collected before and after intervention, blood samples were collected twice to measure liver function, blood glucose, and blood lipids, and part of serum was used for serum metabolomics analysis. The serum samples were analyzed by ultra-performance liquid chromatography/tandem high-resolution mass spectrometry. The data collected were processed in Compound Discover, and then principal component analysis (PCA) and orthogonal partial least squares discriminant analysis were used to establish the profile of differentially expressed blood metabolites between patients and healthy people and perform the enrichment analysis of differentially expressed metabolic pathways. The independent samples t -test was used for comparison of normally distributed continuous data between two groups, and the Wilcoxon non-parametric test was used for comparison of non-normally distributed continuous data between two groups. Results After lifestyle intervention, the patients had significant reductions in body mass index ( P < 0.01), body weight ( P < 0.01), and serum biochemical parameters alkaline phosphatase, albumin, gamma-glutamyl transpeptidase, and alanine aminotransferase (all P < 0.05), as well as a significant reduction in total protein ( P < 0.01), while there were no significant improvements in cholinesterase, aspartate aminotransferase, and glucose. As for the four items for blood lipids, there was a significant reduction in triglyceride ( P < 0.01), while there were no significant improvements in high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and total cholesterol. The metabolomics analysis showed that 33 serum metabolites changed significantly after lifestyle intervention. In addition, PCA results showed that after intervention, the level of metabolites in patients tended to be normal. The signaling pathway analysis showed that exercise and diet mainly affected the pathways of bile acid, unsaturated fatty acid synthesis, and phenylalanine metabolism. Conclusion Lifestyle intervention can achieve varying degrees of reduction in the body weight of patients with NAFLD, improve serum biochemical parameters, and regulate the abnormal metabolic pathway in patients with NAFLD, which has important clinical value and significance for guiding clinicians to formulate reasonable diet and exercise strategies for patients with NAFLD and prevent the progression of NAFLD.
