Our goal was to assess the effectiveness of fine-needle aspiration thyroglobulin (FNA-Tg) in detecting malignant lymph nodes (LNs) in patients with differentiated thyroid cancer (DTC). We also aimed to determine the factors that affect the accuracy of FNA-Tg. We conducted a retrospective cohort study using the laboratory, ultrasonographic, histopathological, FNA cytology (FNA-C), and FNA-Tg results of 176 DTC patients. ⋯ Serum Tg positivity and serum thyroid-stimulating hormone were positively correlated with FNA-Tg levels in detecting malignant LNs. Our study demonstrated that FNA-Tg is a reliable method for detecting LN metastases in DTC patients, with a 3.14 ng/mL cutoff value. However, each center should take into account factors such as serum thyroid-stimulating hormone, serum Tg, and the presence of thyroid tissue when interpreting FNA-Tg results and determining the appropriate cutoff level.

Case Reports
Bile duct injury with formation of right hepatic duct-duodenal fistula after cholecystectomy: A case report.
The management of bile duct injury (BDI) remains a considerable challenge in the department of hepatobiliary and pancreatic surgery. BDI is mainly iatrogenic and mostly occurs in laparoscopic cholecystectomy (LC). After more than 2 decades of development, with the increase in experience and technological advances in LC, the complications associated with the procedure have decreased annually. However, bile duct injuries (BDI) still have a certain incidence, the severity of BDI is higher, and the form of BDI is more complex. ⋯ The successful diagnosis and treatment of this case and the summarization of the imaging features and diagnosis of postoperative BDI have improved the diagnostic understanding of postoperative BDI and provided clinicians with a particular clinical experience and basis for treating such diseases.

Glioma is one of the malignancy brain tumors, which deeply threaten the health of patients. Although the traditional therapies for glioma have improved, the outcome is still far from satisfactory. Bone Marrow Stromal Cells (BMSC)-based therapy provided novel insight in the treatment for glioma. ⋯ Our data suggested that BMSC-derived exosome inhibited the proliferation and contributed to apoptosis of human U87 cells after culturing with miR-506 mimic. Overexpression of miR-506 in BMSC-derived exosome inhibited the invasion of human glioma U87 cells, while these effects were deeply suppressed in the presence GW4869. Our present study demonstrated that BMSC inhibited the growth and metastasis of human glioma U87 cells through delivering exosomal miR-506, and provided the evidences to develop the BMSC-based therapy for glioma.

Mutations in the gene encoding type VI collagen cause Bethlem myopathy (MIM 158810) and Ullrich congenital muscular dystrophy (MIM 254090); 2 diseases previously recognized as completely independent, and have been increasingly recognized. However, collagen-related myopathy caused by intron variation in the COL6 gene is rarely reported in China. Ullrich congenital muscular dystrophy is an autosomal recessive disorder that leads to severe muscle weakness with early onset. Thus, children may never walk independently, with proximal joint contractures and significant hyperelastic distal joints, and have early respiratory failure. Therefore, timely diagnosis and treatment are important. We report a spontaneous mutation in the COL6A2 gene causing Ullrich congenital muscular dystrophy type 1 in a pediatric patient. ⋯ We report a case of spontaneous mutation in the COL6A2 gene causing Ullrich congenital muscular dystrophy type 1 in a pediatric patient, expanding the phenotypic spectrum of the disease and enriching the human gene pool.

We aimed to investigate the validity, reliability, and clinical relevance of Amadeo hand-finger robotic rehabilitation system measurements for evaluating spasticity and strength in hemiplegic patients. In total, 161 participants (107 hemiplegic patients and 54 sex- and age-matched healthy controls) were included in this study. Spasticity was evaluated using the Modified Ashworth Scale, hand motor functions were evaluated using the Fugl-Meyer Assessment Hand Subscale, and hand grip and pinch strength were evaluated using the Jamar hand grip and pinch dynamometer. ⋯ There was a statistically significant positive correlation between the clinical and robotic device results of the Modified Ashworth Scale (r = .72; P < .01). There was a statistically significant positive correlation between the hand strength values measured with the robotic device, Jamar grip, pinch, and Fugl-Meyer Assessment Hand Subscale scores (P < .01) in the patient group. Hand finger spasticity and strength measurements of the Amadeo hand-finger robotic rehabilitation system were valid, reliable, and clinically correlated in stroke patients.
