A growing body of evidence has indicated the important role of autophagy receptors in directing ubiquitinated or non-ubiquitinated cargos towards autophagy. Autophagy receptors bind to LC3 (microtubule-associated protein 1 light chain 3) on phagophore and autophagosome membranes, and recognize signals on cargoes in the delivery system of autophagy. However, the diverse domains in the receptor structures determine that their roles would never be limited to autophagy. Up to date, increasing numbers of the receptor proteins have been demonstrated to serve as a molecular link or switch participating in autophagic degradation, apoptosis or cell survival signals. Here, we highlight the non-autophagic roles of these receptor proteins to draw attention to this growing research topic.

Henoch-Scholein purpura(HSP)is a common systemic vasculitis of the small vessel in children,with a variety of clinical manifestations.The main diagnostic criteria include palpable skin purpura.Patients who have gastrointestinal tract as the main symptoms suffer clinically abdominal pain and gastrointestinal bleeding,they are easily misdiagnosed before skin purpura,the rate of misdiagnosis can be as high as 87.5%,and the main treatment is early application-oriented glucocorticoids.This review include etiopathogenisis,pathogenesis,pathology,clinical manifestations,auxiliary examination and treatment about gastrointestinal manifestations in HSP.

Objective To study the risk factors in elderly moderate-severe thermal burn patients with acute ischemic stroke (AIS).Methods Forty-two elderly moderate-severe thermal burn patients with AIS served as an observation group and 47 elderly moderate-severe thermal burn patients without AIS served as a control group in this study.Risk factors in thermal burn patients with AIS were analyzed by univariate and multivariate logistic regression analysis respectively.Results The number of neutrophils and platelets,hematocrit,serum levels of fibrinogen,thromboxane A2,creatinine,procalcitonin,C-reactive protein,TNF-α and interleukin-6 (IL-6) were significantly higher while the systolic blood pressure (SBP) on admission was significantly lower in observation group than in control group (P＜0.01).Logistic regression analysis showed that SBP on admission,serum levels of fibrinogen,thromboxane A2,TNF-α and IL-6 were the independent risk factors in elderly moderate-severe thermal burn patients with AIS (OR =1.106,95％CI:1.007-1.501,P=0.007;OR=3.316,95 ％ CI:1.251-8.792,P=0.016;OR=1.077,95％CI:1.003-1.156,P=0.041;OR=2.901,95％CI:1.109-2.799,P=0.013;OR=1.502,95％CI:1.581-2.031,P=0.021).Conclusion SBP on admission,serum levels of fibrinogen,thromboxane A2,TNF-α and IL-6 are the independent risk factors in elderly moderate-severe thermal burn patients with AIS.

Objective To observe the changes of MEP(motor evoked pontential) and neurologic function after Erigeron beviscapus(EBHM) preconditioning on spinal cord ischemia-reperfusion injury in rabbits, and provide substructural experimental theory.Methods Twenty-four domestic rabbits were randomly divided into four groups with six rabbits each. In sham group (group A) only the abdominal aorta was exposed. In the blank group (group B), the abdominal aorta was occluded 40 minute followed by reperfusion. In the methylprednisolone group (group C), it was occluded 30 minute before the abdominal, methylprednisolone (30 mg/kg) was injected into the rabbit by vein, which was used for two days after the surgeon. In the EBHM group (group D), EBHM(50 mg/kg) was injected into the rabbit by vein, the following procedure was the same as group C. MEP was measured in each observed point and neurologic function was observed everyday for 7days.Results At every observed point after SCI, the MEP changed regularly, and compared with group B, there was significant difference in groups C and D(P<0.05). 7 days later, the neurologic function changed significantly in each group(P<0.05).Conclusion MEP monitoring can reflect the early change on spinal cord ischemia-reperfusion injury. EBHM preconditioning can protect the rabbit from spinal cord ischemia reperfusion injury.

Objective To investigate the preoperative management and the clinical effeciency of Lichtenstein tension-free hernioplasty in adult patients with inguinal incarcerated hernia.Methods Clinical data of 86 patients with inguinal incarcerated hernia were analyzed retrospectively.Hernia was repaired with Lichtenstein tension free after reposition.Results There were 59 male patients and 27 female patients with median age of (63 ± 18) years.There were 8 patients with liver cirrhosis.The operation was performed successfully in all patients.Segmental bowel resection with end-to-end anastomosis was performed in 38 emergency cases.Operative time was 20-120 min,with an average time of 54 min.The postoperative hospitalization was 5-17 d,with an average of 8 d.There were 7 cases of skin ecchymosis at the scrotum,there were no intestinal perforation,hepatic encephalopathy and upper gastrointestinal hemorrhage after operation.In early series of 24 cases without drainage tube left in place,there were 10 cases of fat liquefaction,10 cases of hydrops of hernial sac,6 cases of seroma and 3 cases of wound infection after operation.After 12 to 48 months of follow-up,there was no mortality after 2 years,no hernia recurrence.Conclusions Tension free repair in the treatment of incarcerated inguinal hernia is safe and feasible.

Objective To evaluate the usefulness of CT and US in the diagnosis of gastrointestinal involvement in children with rheumatoid purpura. Methods Abdominal CT and US findings in 14 cases of clinical and laboratory confirmed of rheumatoid purpura were analyzed. There were 9 males and 5 females with the age ranged from 6 months to 14 years. All patients was hospitalized because of acute abdominal emergency, and the clinical presentations included paroxysm of abdomen pain, vomiting, without skin rashes and subcutaneous hemorrhage. CT examination was done in 7 cases, and contrast enhancement was performed in 1 case. Abdominal ultrasound was done in 9 cases. Both CT and US were done in 2 cases. Results All patients demonstrated multiple or single areas of bowel-wall thickening, localized intraluminal narrowing, mesenteric edema, and liquid in abdominal cavity by CT and ultrasound. Conclusion Abdominal CT and US examination have important values in differential diagnosis of acute abdominal disorders in children patients with rheumatoid purpura. Before appearing skin rashes, classical picture can help for the diagnosis and clinical treatment. Abdominal CT and US examination can also find the intussusception, bowel obstruction, and perforation in rheumatoid purpura.

Objective To evaluate the value and limitation of Gd-DTPA enhanced MRI for neuroblastoma staging in children. Methods Twelve cases of neuroblastoma proved by operation or bone marrow aspiration were examined by gadolinium-enhanced MRI. The age ranged from seven months to five years, mean 3.7 years. Eight tumors originated from adrenal, and four from posterior mediastinum. Conventional sequences, double dose gadolinium-enhanced MRI, and 3D CEMRA were used in all patients. Six cases were examined by CT in same time. Imaging staging on surgic-histopathological-based International Neuroblastoma Staging System (INSS) was performed. Results Six patients were staged by CT, including stage Ⅰ-Ⅱ in 2 cases, stage Ⅲ in 4 cases, and stage Ⅳ in none. Twelve patients were staged by conventional MRI, including stage Ⅰ-Ⅱ in 2 cases, stage Ⅲ in 9 cases, and stage Ⅳ in 1 case. Twelve patients were staged by double dose gadolinium-enhanced MRI, including stage Ⅰ-Ⅱ in 1 case, stage Ⅲ in 1 case, and stage Ⅳ in 10 cases. Conclusion Gadolinium-enhanced MRI was a single best imaging modality for neuroblastoma, most useful for distal to diaphragm metastasis, dumbbell tumor intraspinal extension, and bone marrow metastasis that was not detected by aspirate examination. Enhancement MRI was important in evaluating the therapy and was also helpful in assessing the therapeutic efficacy and relapse. 3D CEMRA helps demonstrate large vascular encasement and tumor erosion into important organs, and it is useful in assessing the respectability. Long examination time and lack in showing the characteristic calcium were the limitations.
