Autologous bone marrow stem cell transplantation for the treatment of type 2 diabetes mellitus.
Autologous peripheral stem cell transplantation was first reported in 2007 to treat type 1 diabetes mellitus (DM) and achieved encouraging effect, but whether similar outcome can be achieved in type 2 DM is not well demonstrated. The objective of this study was to determine the effect of combination of autologous bone marrow stem cell transplantation (BMT) and hyperbaric oxygen treatment on type 2 DM. ⋯ Combined therapy of intrapancreatic BMT and hyperbaric oxygen treatment can improve glucose control and reduce the dose of insulin and/or oral hypoglycemic drugs in type 2 DM patients, but it only improve pancreatic β-cell function transiently. Further randomized controlled clinical trials involved more patients will be required to confirm these findings and the mechanism needs to be illustrated deeply.

Genetic variability in adapter proteins with APPL1/2 is associated with the risk of coronary artery disease in type 2 diabetes mellitus in Chinese Han population.
Adaptor proteins containing PH domain, PTB domain, and leucine zipper motif 1 and 2 (APPL1/2) play a key role in cell proliferation in many tissues. APPL1 or APPL2 as an adaptor for adiponectin receptors mediates the signaling pathway of adiponectin which acts as an anti-atherosclerotic adipokine. This study aimed to investigate whether genetic variations in the APPL1/2 genes affect the risk of coronary artery disease (CAD) in Chinese patients with type 2 diabetes mellitus (T2DM). ⋯ Genetic variation(s) in APPL1/2 may be associated with CAD risk in T2DM in Chinese population.

Radiofrequency thermocoagulation rhizotomy for recurrent trigeminal neuralgia after microvascular decompression.
Microvascular decompression (MVD) is a well accepted surgical treatment strategy for trigeminal neuralgia (TN) with satisfying long-term outcome. However, considerable recurrent patients need more effective management. The purpose of this study was to evaluate the effectiveness of radiofrequency thermocoagulation rhizotomy (RTR) on patients with recurrent TN after MVD. ⋯ RTR was effective in alleviating the pain of TN cases suffering from unsuccessful MVD management. With the help of virtual reality imaging technique or neuronavigation system, the patients could attain better long-term pain relief.

Quantify work load and muscle functional activation patterns in neck-shoulder muscles of female sewing machine operators using surface electromyogram.
Work-related musculoskeletal disorders (WMSDs) have high prevalence in sewing machine operators employed in the garment industry. Long work duration, sustained low level work and precise hand work are the main risk factors of neck-shoulder disorders for sewing machine operators. Surface electromyogram (sEMG) offers a valuable tool to determine muscle activity (internal exposure) and quantify muscular load (external exposure). During sustained and/or repetitive muscle contractions, typical changes of muscle fatigue in sEMG, as an increase in amplitude or a decrease as a shift in spectrum towards lower frequencies, can be observed. In this paper, we measured and quantified the muscle load and muscular activity patterns of neck-shoulder muscles in female sewing machine operators during sustained sewing machine operating tasks using sEMG. ⋯ Female sewing machine operators were exposed to high sustained static load on bilateral neck-shoulder muscles; left neck and shoulder muscles were held in more static positions; the 7th, 16th, and 20th time windows were muscle fatigue period that ergonomics intervention can protocol at these periods.
