The value of radiomics based on contrast-enhanced MRI in predicting the recurrence of acute pancreatitis / 中华放射学杂志

Objective:To evaluate the value of radiomics analysis based on enhanced MRI in predicting the recurrence of acute pancreatitis (AP).Methods:From January 2017 to December 2020, 201 patients diagnosed with AP were collected retrospectively in the Affiliated Hospital of North Sichuan Medical College. These patients underwent plain and enhanced MRI within 7 days after onset. After clinical follow-up, 102 cases were classified as non-recurrence AP group and 99 cases were classified as recurrent acute pancreatitis (RAP) group. They were divided into training set (140 cases, 71 cases in non-recurrence AP group, 69 cases in RAP group) and validation set (61 cases, 31 cases in non-recurrence AP group, 30 cases in RAP group) using a random number table method. The independent sample t-test, Mann-Whitney U test or χ 2 test were used to compare the clinical characteristics between the two groups, and the clinical characteristics with statistical differences were included in logistic regression to construct the clinical model. The quantitative features of radiomics were extracted based on the late arterial-phase images of contrast-enhanced MRI. The best radiomics features retained after dimensionality reduction were used to construct the radiomics model through logistic regression analysis, and a combined model was constructed by combining the clinical features. The prediction ability of the models was evaluated by the receiver operating characteristic curve, and the area under the curve (AUC) was compared by DeLong test. Results:There were statistical differences in gender, severity, local complications, hyperlipidemia and smoking between non-recurrence AP group and RAP group (all P<0.05). Hyperlipidemia was an independent risk factor for AP recurrence (OR=5.236, 95%CI 2.710-10.101). The 9 best radiomics features by dimensionality reduction were selected to construct a radiomics model. The AUCs of clinical model, radiomics model and combined model in the training set were 0.803, 0.944 and 0.978 respectively, and those in the validation set were 0.678, 0.940 and 0.955 respectively. In the training set and the validation set, the prediction ability of the radiomics model and combined model were higher than those of the clinical model (training set: Z=3.28, 4.83, P=0.001,<0.001; validation set: Z=3.48, 4.05, both P<0.001). Conclusions:The radiomics model based on late arterial-phase enhanced MRI has good quantitative prediction ability for the recurrence of AP, which can provide a reference for the prevention and treatment of RAP.

Objective:To explore the effects of small-incision carpal tunnel release on postoperative functional recovery and electrophysiological indexes in carpal tunnel syndrome (CTS).Methods:A total of 75 patients with CTS treated in Shulan (Hangzhou) Hospital were enrolled as the research objects between April 2016 and April 2021. According to different surgical methods, they were divided into group A (34 cases, small-incision carpal tunnel release) and group B (41 cases, traditional carpal tunnel release). The operation time, hospitalization time, time to resume work, electrophysiological indexesbefore and after surgery, and postoperative complications were compared between the two groups.Results:Compared with group B, operation time, hospitalization time and time to resume work were shorter in group A: (12.32 ± 3.26) min vs. (34.65 ± 7.49) min, (5.15 ± 1.68) d vs. (7.83 ± 2.24) d, (18.22 ± 2.03) d vs. (37.35 ± 3.16) d ( P<0.05). After surgery, electrophysiological indexes in both groups were improved ( P<0.05), but there was no significant difference between the two groups ( P>0.05). The incidence rates of scar pain, decreased grip strength and hand piercing pain in group A were lower than those in group B: 2.94%(1/34) vs. 19.51%(8/41), 0 vs. 21.95%(9/41), 0 vs. 12.20%(5/41) ( P<0.05). Conclusions:Compared with traditional carpal tunnel release, clinical curative effect of small-incision carpal tunnel release is comparable on CTS patients. However, it can shorten operation time, hospitalization time and time to resume work, reduce incidence of postoperative complications.

Akinesia deformation sequence in a fetus suspected by prenatal ultrasound and confirmed after mid-term termination / 中华围产医学杂志

We report a case of fetal akinesia deformation sequence (FADS), which was prenatally suspected on ultrasound and confirmed by whole exome sequencing and Sanger sequencing after mid-term termination. Prenatal ultrasonography revealed multiple abnormalities in a fetus at 21 +4 weeks of gestation, consisting of fixed posture of limbs, narrow thorax, markedly shrunken gastric vacuole, and thickened nuchal fold. After genetic counseling, the pregnancy was terminated, and the appearance of the fetus was consistent with the ultrasound findings. Whole exome sequencing and Sanger sequencing of the fetal tissue verified a compound heterozygous variation of the RAPSN gene--c.149_153delins AGATGGGCCGCTACAAGGAGATGG (p.V50Efs*114) and c.227T>C (p.L76P), which were inherited from the father and mother, respectively, ultimately confirming the diagnosis of FADS.

Tantalum rod implantation versus fibular fixation in the treatment of osteonecrosis of the femoral head at early stage / 中国组织工程研究

BACKGROUND: Fibular fixation and tantalum rod implantation are two commonly used methods for the treatment of early osteonecrosis of the femoral head (ONFH), both of which can effectively delay or even reverse the progress of ONFH. However, further comparative evaluation on their mechanical properties and therapeutic efficacy is required.OBJECTIVE: To compare the clinical efficacy of fibular fixation and tantalum rod implantation on ONFH at early stage.METHODS: Fifty-eight patients (81 hips) suffered from ONFH with ARCO stage 1 and stage 2, and underwent fibular fixation (30 cases, 41 hips) or tantalum rod implantation (28 cases, 40 hips). Postoperatively, both groups were followed up for over 2 years. The Harris scores of the hip were compared between two groups before and after treatment. With femoral head collapse and the collapse distance > 4 mm as observation points, the survival rate of the femoral head was compared between two groups.RESULTS AND CONCLUSION: The postoperative Harris scores of the two groups were significantly improved than before (P 4 mm collapse as the observation point, the Kaplan-Meier survival curve showed that overall survival rate of the hip was 95% in the fibular fixation group and 83% in the tantalum rod implantation group. After examined by log-rank (Mantel-Cox), there was a significant difference in the survival rate of the hip at Stage IIC between two groups (P=0.0418). To conclude, both fibular fixation and tantalum rods implantation applied to ONFH at early stage can effectively improve the hip function, and the survival rate of the hip at ARCO Stage IIC is better in patients undergoing fibular fixation than tantalum rod implantation.
