Recent clinical outcomes of multi-regimen chemotherapy in patients with cholangiocarcinoma (CCC) have shown benefits in terms of overall survival. However, repeated endoscopic biliary drainage (EBD) and serious adverse events negatively affect prolongation of the survival period.The aim of this study was to investigate the prevalence of massive hemobilia and the outcomes of its management with fully covered self-expandable metal stents (FC-SEMSs) in patients with hilum-involving CCC receiving multi-regimen chemotherapy. The methods and effects of FCSEMS placement were retrospectively investigated following the occurrence of massive hemobilia during EBD. A total of 356 patients with CCC received multi-regimen chemotherapy. Among them, 181 patients had hilar invasion, and seven patients (3.9%) developed massive hemobilia during repeated EBD using removable stents. In all cases, the tumor encased the right hepatic artery. In six patients (85.7%), hemostasis was immediately and completely achieved by inserting one or two FC-SEMSs proximal to the hilar invasion area. Therefore, if the tumor encases the right hepatic artery, massive hemobilia is likely to occur during multi-regimen chemotherapy.Thus, prompt placement of a FC-SEMS would be an effective treatment option for massive hemobilia in patients with hilum-involving CCC.

Prolotherapy is a treatment that induces tissue regeneration. Traditionally, various stimulants have been used as proliferative agents, but currently, high-concentration dextrose solutions, which have relatively excellent safety and effectiveness, are mainly used. Prolotherapy induces inflammation by injecting a proliferant into a weakened ligament or tendon enthesis and uses the process of proliferation and remodeling of the damaged tissue. The effectiveness of prolotherapy for different musculoskeletal diseases has been reported, but each author reported a different protocol because the method, number of procedures, and cycle have not been standardized. Therefore, the authors conducted a systematic literature review on prolotherapy to analyze the protocols and clinical outcomes of prolotherapy. This paper presents the current knowledge on the diseases targeted by prolotherapy and the treatment methods for each disease.

Postoperative pain is one of the most common reasons for delayed discharge and can impede the recovery of joint motion and rehabilitation. Recently, an ultrasound-guided nerve block was shown to be the most effective method to control postoperative pain. Under ultrasound guidance, orthopedic surgeons can safely perform the nerve block procedure. This review discusses th

Journal of Lipid and Atherosclerosis 2022;11(1):55-72
Objective:
Glucagon in mammals and its homolog (adipokinetic hormone [AKH] in Drosophila melanogaster) are peptide hormones which regulate lipid metabolism by breaking down triglycerides. Although regulatory mechanisms of glucagon and Akh expression have been widely studied, post-transcriptional gene expression of glucagon has not been investigated thoroughly. In this study, we aimed to profile proteins binding with Gcg messenger RNA (mRNA) in mouse and Akh mRNA in Drosophila.
Methods:
Drosophila Schneider 2 (S2) and mouse 3T3-L1 cell lysates were utilized for affinity pull down of Akh and Gcg mRNA respectively using biotinylated anti-sense DNA oligoes against target mRNAs. Mass spectrometry and computational network analysis revealed mRNA-interacting proteins residing in functional proximity.
Results:
We observed that 1) 91 proteins interact with Akh mRNA from S2 cell lysates, 2) 34 proteins interact with Gcg mRNA from 3T3-L1 cell lysates. 3) Akh mRNA interactome revealed clusters of ribosomes and known RNA-binding proteins (RBPs). 4) Gcg mRNA interactome revealed mRNA-binding proteins including Plekha7, zinc finger protein, carboxylase, lipase, histone proteins and a cytochrome, Cyp2c44. 5) Levels of Gcg mRNA and its interacting proteins are elevated in skeletal muscles isolated from old mice compared to ones from young mice.
Conclusion
Akh mRNA in S2 cells are under active translation in a complex of RBPs and ribosomes. Gcg mRNA in mouse precursor adipocyte is in a condition distinct from Akh mRNA due to biochemical interactions with a subset of RBPs and histones. We anticipate that our study contributes to investigating regulatory mechanisms of Gcg and Akh mRNA decay, translation, and localization.

STUDY DESIGN: Literature review. OBJECTIVE: Ultrasound-guided injections are a common clinical treatment for lower lumbosacral pain that are usually performed before surgical treatment if conservative treatment fails. The aim of this article was to review ultrasound-guided injections in the lumbar and sacral spine. SUMMARY OF LITERATURE REVIEW: Ultrasound-guided injections, unlike conventional interventions using computed tomography or C-arm fluoroscopy, can be performed under simultaneous observation of muscles, ligaments, vessels, and nerves. Additionally, they have no radiation exposure and do not require a large space for the installation of equipment, so they are increasingly selected as an alternative method. MATERIALS AND METHODS: We searched for and reviewed studies related to the use of ultrasound-guided injections in the lumbar and sacral spine. RESULTS: In order to perform accurate ultrasound-guided injections, it is necessary to understand the patient's posture during the intervention, the relevant anatomy, and normal and abnormal ultrasonographic findings. Facet joint intra-articular injections, medial branch block, epidural block, selective nerve root block, and sacroiliac joint injections can be effectively performed under ultrasound guidance. CONCLUSIONS: Ultrasound-guided injections in the lumbar and sacral spine are an efficient method for treating lumbosacral pain.

PURPOSE: The purpose of this study was to analyze any effectiveness, advantages, and the procedure of an ultrasound-guided suprascapular nerve block via the proximal approach in patients suffering from shoulder pain. MATERIALS AND METHODS: A total of 51 patients treated with nerve block between November 2015 and November 2016 were analyzed. We identified the suprascapular nerve that branches off the superior trunk of the brachial plexus, and found the suprascapular nerve, which is located in the fascial layer between the inferior belly of the omohyoid muscle and the serratus anterior muscle. We then performed a nerve block. We evaluated the visual analogue scale (VAS) of pre- and post-nerve block, and the visualization of the nerve, depth from the skin to the nerve, angle of needle entry, as well as complications. Moreover, we measured the visualization of the nerve, depth from the skin to the nerve in a classic approach, and compared it with the proximal approach. RESULTS: There was significant improvement (p < 0.05) in the mean VAS, from 7.1 to 3.4, without any major complications. Compared with the classic approach, we were able to identify the suprascapular nerve much better (classic 25.5%/proximal 96.1%), and the mean distance from the skin to the nerve (classic 38 mm/proximal 12 mm) was significantly short (p < 0.05), and the mean angle of needle entry was 19 degrees in the proximal approach. CONCLUSION: In an ultrasound-guided suprascapular nerve block by proximal approach, the nerve and needle tip can be more easily identified, which increases accuracy; with a small amount of local anesthetic, more effective pain control can be achieved. Hence, this approach is an effective alternative pain control method for patients suffering from shoulder pain.
