Objective:To investigate the value of CT radiomics mode in differential diagnosis of benign and malignant thyroid nodules.Methods:The clinical and imaging data of 179 patients with thyroid nodules confirmed by pathology from May 2017 to August 2018 were retrospectively analyzed in the Affiliated Huaian First People′s Hospital of Nanjing Medical University. Among the patients, 89 cases were benign nodules and 90 cases were malignant nodules. All patients underwent unenhanced and enhanced CT scan before operation. The stratified random sampling method was used to divide patients into a training group (143 cases) and a testing group (36 cases) according to a ratio of 8∶2. The A.K software was used to extract 378 imaging omics features based on preoperative CT images, and then Spearman correlation analysis and least absolute shrinkage and selection operator regression analysis were used for feature selection and model construction. The receiver operating characteristic (ROC) curve was used to verify the model in the training group and the testing group, and the efficacy of imaging omics features to predict benign and malignant thyroid nodules was evaluated.Results:After feature screening, 16 radiomics features were used to construct an identification model between benign and malignant thyroid nodules. In the training group, the area under the ROC curve (AUC) was 0.92 [95% confidence interval (CI): 0.88-0.97], the sensitivity and specificity were 88.7%, 82.0%, and the diagnostic accuracy of the model was 91.1%. In the testing group, AUC was 0.90 (95 %CI: 0.81-0.98), sensitivity and specificity were 88.5%, 84.6%, and the diagnostic accuracy of the model was 88.2%. Conclusion:The CT radiomics mode has a good diagnostic performance in the identification of benign and malignant thyroid nodules.

One case of knee infection after anterior cruciate ligament reconstruction caused by the gram-positive anaerobic bacterium Finegoldia magna was reported. The patient was admitted to hospital due to fever and knee joint swelling and pain after anterior cruciate ligament reconstruction. Through medical history, physical examination, imaging examination and next-generation sequencing, it was confirmed that the infection was caused by Finegoldia magna. Through literature review, 37 literatures on infectious diseases caused by Finegoldia magna was retrieved and analyzed, and the identification points of anaerobic bacteria, the application of second-generation sequencing technology and the treatment status of infection after anterior cruciate ligament reconstruction were reviewed. The incidence of infection after arthroscopic anterior cruciate ligament reconstruction is low, while anaerobic infection is even more rare and difficult to culture. The next-generation sequencing can be used to assist the diagnosis. On the basis of giving priority to the preservation of the reconstructed ligament, the combined use of arthroscopic debridement, irrigation and sensitive antibiotics is the main treatment method.

Histone deacetylases are involved in many biological processes and have roles in regulating cell behaviors such as cell cycle entry, cell proliferation and apoptosis. However, the effect of histone deacetylases on the development of hair cells (HCs) has not been fully elucidated. In this study, we examined the influence of histone deacetylases on the early development of neuromasts in the lateral line of zebrafish. Hair cell development was evaluated by fluorescent immunostaining in the absence or presence of histone deacetylase inhibitors. Our results suggested that pharmacological inhibition of histone deacetylases with inhibitors, including trichostatin A, valproic acid and MS-275, reduced the numbers of both HCs and supporting cells in neuromasts. We also found that the treatment of zebrafish larvae with inhibitors caused accumulation of histone acetylation and suppressed proliferation of neuromast cells. Real-time PCR results showed that the expression of both p21 and p27 mRNA was increased following trichostatin A treatment and the increase in p53 mRNA was modest under the same conditions. However, the expression of p53 mRNA was significantly increased by treatment with a high concentration of trichostatin A. A high concentration of trichostatin A also led to increased cell death in neuromasts as detected in a TUNEL assay. Moreover, the nuclei of most of these pyknotic cells were immunohistochemically positive for cleaved caspase-3. These results suggest that histone deacetylase activity is involved in lateral line development in the zebrafish and might have a role in neuromast formation by altering cell proliferation through the expression of cell cycle regulatory proteins.

Objective To explore the transformation of three-dimensional curve,and to observe effect of three-dimensional remodeling surgery in order to find an ideal method to achieve upper eyelid rejuvenation.Methods Retrospective analysis was conducted after surgical correction for three-dimensional reconstruction in 48 patients with upper eyelid that were female,aged 58 to 76 years;all of them had simultaneous surgery of both eyes.Using double eyelid crease incision to remove loose and redundant skin,we transplanted the herniated fat of the medial orbital septum to the deep surface of the orbicularis oculi muscle in the distinct bony structure of the extra-supraorbital margin,folded and lifted orbital septum fascia;at the same time lifted eyebrow through eyebrow incision,transplanted and filled dermis and muscle fascia flap to remodel the transverse S-shaped stereo curve of the coronal plane of the upper eyelid.Results A lot of 41 cases were followed up more than 6 months from 48 patients,except that one patient had a second surgery due to double eyelid asymmetry after one year,eyelid rejuvenation in 40 patients were improveed.Effect of 33 cases was satisfactory.Satisfaction rate was 80.49％.Less satisfaction were 6 cases,accounting for 14.63％.No satisfaction was 1 case,ac counting for 2.44 ％.Conclusions The surgery can reshape the concavity inside,the full crown outside of upper eyelid by the skin removing,fat shifting,leather fat muscle flap filling,and restore the upper eyelid to three-dimensional full round young shape.It is an ideal surgical method for eye anti-aging treatment.

A 24-year female with abdominal pain and fever for 4 days was admitted. The blood culture showed Leuconostoc growth, and sputum culture showed positive Acinetobacterbaumannii. The diagnosis Leuconostoclactis bacteremia following small intestinal perforation was confirmed; surgical treatment was performed and the infection was controlled by piperacillin sodium and tazobactam combined with tegacycline. Wanfang database, CNKI, PubMed and Embase database up to September 2020 were searched with the keywords of " Leuconostoc lactis" "infection" "bacteraemia" for relevant literature. A total of 32 cases were reported in the literature, of whom 13 (39.4%) were infants, 17 (51.5%) had catheter-related bloodstream infection, and one healthy adult male had bacteremia through gastrointestinal perforation. In 20 patients treated with penicillins-based antibiotics, 18 were cured with an effective rate of 90.0%. The results suggest that Leuconostoc infection is likely to occur in the infants, but adults can still get community-acquired Leuconostoc infection. Most β-lactams are susceptible to Leuconostoc, but some exhibit resistance, so it is recommended to select antimicrobial agents based on drug susceptibility.

Chronic high-salt diet-associated renal injury is a key risk factor for the development of hypertension. However, the mechanism by which salt triggers kidney damage is poorly understood. Our study investigated how high salt (HS) intake triggers early renal injury by considering the ‘gut-kidney axis’. We fed mice 2% NaCl in drinking water continuously for 8 weeks to induce early renal injury. We found that the ‘quantitative’ and ‘qualitative’ levels of the intestinal microflora were significantly altered after chronic HS feeding, which indicated the occurrence of enteric dysbiosis. In addition, intestinal immunological gene expression was impaired in mice with HS intake. Gut permeability elevation and enteric bacterial translocation into the kidney were detected after chronic HS feeding. Gut bacteria depletion by non-absorbable antibiotic administration restored HS loading-induced gut leakiness, renal injury and systolic blood pressure elevation. The fecal microbiota from mice fed chronic HS could independently cause gut leakiness and renal injury. Our current work provides a novel insight into the mechanism of HS-induced renal injury by investigating the role of the intestine with enteric bacteria and gut permeability and clearly illustrates that chronic HS loading elicited renal injury and dysfunction that was dependent on the intestine.
