Objective To improve lesion detection of the radial head with adjusted elbow joint lateral position on X-ray.Methods (1)20 subjects underwent elbow joint CT three-dimensional reconstruction (average intensity projection),which was as X-ray radio-graphy image.The tilt angle of the humerus and the projection direction for fully display of the radial head in projection images and the tilt angle of the humerus against detector in X-ray radiography were measured.(2)20 subjects (patients and volunteers)with el-bow joint disease underwent routine and improved elbow joint lateral position were enrolled.And assessed the bare blocking rate of the radial head articular surface of the two positions.Results (1)The angle between the the humerus and the direction of projection were 49°-60°and 30°-41°in CT and X-ray,respectively.The average angle was (35.5±1)°.(2).The blocking rate and bare bloc-king rate of the radial head articular surface in routine elbow joint lateral position were 71.6%-100% and 0%-28.4%,respective-ly.The average rate of bare blocking was 14.2%.Fracture 13 cases and 5 cases of suspected fractures.The blocking rate and bare blocking rate of the radial head articular surface in improved elbow joint lateral position were 4.8%-25% and 75%-95.2%,re-spectively.The average rate of bare blocking was 85.1%.Fracture 1 7 cases and 1 case of suspectet fractures.Conclusion The im-proved elbow joint lateral position of X-ray can display the radial head articular surface better than the routine position.

Exosomes are tiny vesicles produced in cells which sizes between 40 to 100 nm. Exosomes are carriers of cell signal transduction. Thyroid cancer is the common malignant tumor in endocrine system. Exosomes show the regulatory role in thyroid cancer about occurrence, development and metastasis. This review focuses on the relevant characteristics of exosomes and the research progress of exosomes in thyroid cancer.

Wearable devices are used in the new design of the maternal health care system to detect electrocardiogram and oxygen saturation signal while smart terminals are used to achieve assessments and input maternal clinical information. All the results combined with biochemical analysis from hospital are uploaded to cloud server by mobile Internet. Machine learning algorithms are used for data mining of all information of subjects. This system can achieve the assessment and care of maternal physical health as well as mental health. Moreover, the system can send the results and health guidance to smart terminals.

Objective To evaluate the surgical treatments of refractory sclerosing peritonitis related peritoneal dialysis.Methods Clinical data of 15 patients with refractory sclerosing peritonitis related to peritoneal dialysis treated in the General Surgery Department of the 900th Hospital of the Joint Logistics Support Force of the People's Liberation Army from June 30,2014 to May 30,2018.Among them,5 cases underwent"open abdomen peritoneal catheter removal+intestinal adhesiolysis+abdominal infection flushing and drainage with catheter",4 cases underwent"laparoscopic peritoneal catheter removal+intestinal adhesiolysis+abdominal infection flushing and drainage with catheter",3 cases underwent"laparoscopic peritoneal dialysis catheter removal+abdominal infection flushing and drainage with catheter",2 cases underwent"open abdomen peritoneal dialysis catheter removal+abdominal infection flushing and drainage with catheter",and 1 case underwent"laparoscopic examination combined with laparotomy exploration and removal of lower abdominal catheter+intestinal adhesiolysis+abdominal infection flushing and drainage with catheter".Age,gender,clinical symptoms,abdominal CT examination,peripheral blood routine,blood biochemistry,blood C-reactive protein(CRP),white blood cells,biochemistry,and aetiology of peritoneal dialysis fluid were collected and followed up,and the therapeutic effect was evaluated.Results 15 patients were transferred to the Department of Surgery after ineffective treatment in the Department of Internal Medicine.Preoperatively(after 5 days of antibiotic treatment)compared to before antibiotic treatment,there were no significant changes in blood WBC,blood NEUT%,CRP,and peritoneal fluid WBC(P>0.05).Laparoscopic exploration or laparotomy exploration was performed,during which the peritoneal dialysis catheter was removed and the abdominal infection focus was cleared.A pelvic cavity washout drainage tube was left in place postoperatively.Fourteen patients had a good recovery after surgery,with effective control of peritonitis symptoms and no complications such as intestinal obstruction or enterocutaneous fistula.After the removal of the peritoneal dialysis catheter,all patients switched to hemodialysis.A comparison of inflammatory markers before and after surgery showed a significant decrease after surgery.Three days postoperatively compared to before surgery(after 5 days of antibiotic treatment),there were no significant changes in blood WBC,blood NEUT%,CRP,and peritoneal fluid WBC(P>0.05).Seven days postoperatively compared to before surgery(after 5 days of antibiotic treatment),there was a significant decrease in blood WBC[(7.43±2.65)× 109/L VS(10.17±5.24)× 109/L],blood NEUT%[(88.23±9.02)%VS(85.07±11.57)%],and CRP[(152.88±113.01)mg/L VS(114.49±92.97)mg/L](P<0.05);the peritoneal fluid WBC at 7 days postoperatively showed no significant change compared to before surgery(after 5 days of antibiotic treatment)(P>0.05).The cases were followed up for at least 22 months,and 13 patients did not experience peritonitis or intestinal obstruction again.One patient died 39 days after surgery due to multiple organ failure,and one patient died from other causes after a 2-year follow-up.Conclusion For refractory sclerosing peritonitis related peritoneal dialysis that is ineffective in medical conservative treatment,On the basis of reasonable and effective antibiotics to control infection,surgical intervention should be actively carried out and surgical methods such as surgery should be used to control the progress of peritonitis,reduce mortality and improve the cure rate.

The proteolysis targeting chimeras (PROTACs) technology has been rapidly developed since its birth in 2001, attracting rapidly growing attention of scientific institutes and pharmaceutical companies. At present, a variety of small molecule PROTACs have entered the clinical trial. However, as small molecule PROTACs flourish, non-small molecule PROTACs (NSM-PROTACs) such as peptide PROTACs, nucleic acid PROTACs and antibody PROTACs have also advanced considerably over recent years, exhibiting the unique characters beyond the small molecule PROTACs. Here, we briefly introduce the types of NSM-PROTACs, describe the advantages of NSM-PROTACs, and summarize the development of NSM-PROTACs so far in detail. We hope this article could not only provide useful insights into NSM-PROTACs, but also expand the research interest of NSM-PROTACs.
