In recent years, the targeted protein degradation technology has developed quickly, with proteolysis-targeting chimera (PROTAC) as the best-known strategy through exploring the ubiquitin-proteasome system. A number of new targeted protein degradation strategies have been emerging to expand the scope of protein degradation technology, including lysosome-targeting chimeras (LYTACs), autophagy-targeting chimeras (AUTACs), autophagosome-tethering compounds (ATTECs) and chimeras based on chaperone-mediated autophagy (CMA). The emerging methodologies have explored another important protein degradation system in eukaryotes-lysosomal systems, such as the endosome-lysosome pathway and the autophagy-lysosome pathway. This review summaries the mechanisms and features of different strategies for targeted protein degradation, with a special emphasis on the new targeted protein degradation technologies, such as their current status, advantages and limitations.

To study the name of Wenyujin Rhizoma Concisum and Film Turmeric by literature research methods provide the basis for correct application of Cuba in modern clinical application. Wenyujin Rhizoma Concisum and Film Turmeric often called each other mutual generation and used as the same kind of medicine in the ancient prescriptions books. They were often recorded and stated as the same species of Curcumae Longae Rhizoma. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma also often called each other mutual generation in the ancient prescriptions books and used as the same kind of medicine. Wenyujin Rhizoma Concisum was often recorded and stated under the Curcumae Longae Rhizoma articles in the ancient materia medica literatures. Ancient literatures on Wenyujin Rhizoma Concisum records were almost the same, the modern literatures on the records of the sources of Wenyujin Rhizoma Concisum were inconsistency. Inconsistency of Wenyujin Rhizoma Concisum source records in modern literatures was related to the changes of the modern records on source records about Curcumae Longae Rhizoma, Root-tuber of Aromatic Curcumae Longae Rhizoma and Zedoray. The author thinks that Wenyujin Rhizoma Concisum is the ancient Film Turmeric which referes to the same medicine as Curcumae Longae Rhizoma. The source of it just as the Curcumae Longae Rhizoma is not only one kind. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma have been recorded as two medicines at the present, and the source of them simply referes to the original plant Curcuma wenyujin. When using ancient prescriptions, we need to understand the changes that Curcumae Longae Rhizoma and Wenyujin Rhizoma Concisum are the same in ancient but different today in order to choose medicine correctly in the clinical.

Orobanche caerulescens is an important medicinal resource in Orobanchaceae. The present study aims to establish methods for determination of acteoside, crenatoside, and total phenylethanoid glycosides in O. caerulescens, and determine the content in 15 samples to evaluate the resource utilization of this medicinal plant. The content of acteoside and crenatoside were quantitatively determined by HPLC, while total phenylpropanoid glycosides was estimated by UV-VIS spectrophotometry. According to the results, the content of acteoside was the highest in O. caerulescens, followed by crenatoside. The contents of acteoside, crenatoside, and total phenylethanoid glycosides were between 1.15% - 15.60%, 0.83% - 4.47%, and 6.78% - 27.43%, respectively, which had significant differences. The acquisition time has great influence on the content of main components of O. caerulescens. The content of phenylethanoid glycosides is higher in the samples which were collected at the flowering stage. The two determination methods were proved to be simple, accurate and reliable, and can be used to evaluate the quality and resource utilization of O. caerulescens.

Objective To discuss the value of double-row allograft bone suture anchor in repair of rotator cuff injury. Methods Under assistance of arthroseope, 16 cases of rotator cuff lesions were repaired by using double-row allograft bone suture anchors. There were 10 males and 6 females at average age of 44 years (32-58 years). According to Bigliani classification, there were 6 cases of small ruptures, 8 medial ruptures and 2 large ruptures. After rotator cuff was trimmed and acromial bone was re-shaped under arthroscopy, 2 bone anchors attached to suture lines were implanted in the attachment point of rotate cuff of humerus greater tuberosity side by side. Then, the 4 ends of the 2 suture lines were vertically sutured through tendon of supraspinatus mnscle and tied separately, crossing the 4 ends of 2 knots and penetrated each 2 ends into one bone anchor. Finally, these 2 bone anchors were embedded into 2 predrilled bone holes which were parallel to the former 2 anchors and lower in humerus greater tuberosity. Thus, a web was formed and overlapped on the ruptured rotator cuff. The number of bone anchors was according to the size of rupture. Results All cases were followed up for average 14 months (6-23 months). The mean UCLA score was (21.30±5.6) points preoperatively and (32.4±5.8) points postoperatively. The function of shoulders recovered well, with no pain, recurrence or pulling out of bone anchor. Function was excellent in 10 cases, good in 5 and fair in 1. Conclusions As for repair of rotator cuff injury, double-row bone-anchors under arthroscope can provide a tendon-bone interface better suited for biologic healing of rotator cuff. Bone suture anchor can not leave any foreign object residual and costs less.

Objective To study the impact of Paeoniflorin (PF) on α-synuclein degradation pathway. Methods PC12 cells were treated with or without MPP+ (0.5mM) for 24 h, then treated with Paeoniflorin (50 uM) or Rapamycin (0.2 μg/ml) for 24 h. The proliferative activity of cells was detected with the MTT method , and then the protein expression levels of α-synuclein, microtubule-associated protein light chain 3 (LC3-II) and E1 were detected by Western Blot. The expressions of α-synuclein and LC3 were detected by confocal microscopy. Results (1) CAT and SOD activity were significantly decreased after PF and RAPA treatment compared with MPP+ (P < 0.001). (2)MPP+ activated both LC3-Ⅱand E1. MPP+ promoted the increase ofLC3-Ⅱ but inhibited E1. PF significantly upregulated both LC3-Ⅱ (autophagy) and E1 expression (ubiquitin-proteasome pathway) (P < 0.001), promoted degradation of α-synuclein, and reduced cell damage. (3) MPP+enhanced immunofluorescence signal of intracellular α-synuclein and LC3. Fluorescence intensity of α-synuclein decreasedafter PF treatment. Conclusion PF may significantly upregulate both autophagy and ubiquitin proteasome pathways, promote the degradation of α-synuclein and reduce cell damage. These findings suggest Paeoniflorin may be a potential therapy for neurodegenerative diseases.
