The aim of this study is to examine the effect of 18-month Baduanjin exercise on shoulder joint function in maintenance hemodialysis (MHD) patients. 60 MHD patients aged 18-75 will included in this study and randomly divided into two groups (intervention group and control group). The intervention group will be led by a professional person and underwent Baduanjin exercise three times a week before hemodialysis. The control group maintained routine treatment and daily activities.
Essential tremor (ET) is one of the most common movement disorders in adults. The prevalence rate among the elderly over 65 years old is about 4.6%. Tremor usually worsens with age, leading to disability and loss of independence, which has an adverse impact on the quality of life of patients. However, the traditional first-line treatment drugs are neither effective enough nor completely safe for ET patients. Although surgical procedures such as deep brain stimulation (DBS) and thalamotomy can be used to better control unilateral limb tremor, many patients are reluctant to choose surgical treatment because it's invasive. Therefore, there is an urgent need to develop new drugs or non-invasive therapies as a better treatment option for ET. The pathology of the disease is not yet clear, it is generally believed that genetic, aging and environmental factors are related to ET. Hyperactivity of cerebellar function and changes of cerebello-thalamo- cortical (CTC) pathways are currently considered to be the most important pathophysiological mechanisms of ET. Therefore, the cerebellum and cortex may be the best targets for the treatment of tremor. Continuous theta burst stimulation (cTBS) is one of the non-invasive electrophysiological techniques characterized by plexus stimulation, which is similar to low-frequency repetitive transcranial magnetic stimulation (rTMS) but closer to the physiological state of neural activity, and may inhibit the excitability of the stimulated cortex. The stimulation duration is greatly shortened, which is simpler and easier than the low-frequency rTMS of 20-30 minutes. In addition, functional near infrared spectroscopy (fNIRS) is a new non-invasive functional neuroimaging technique. It mainly uses the difference characteristics of oxyhemoglobin and deoxyhemoglobin in brain tissue for near-infrared light absorption at different wavelengths of 600-900nm. The efficacy, safety, and mechanisms involved in non-invasive stimulation therapy for ET patients are still unclear. There are few studies on the treatment of ET with cTBS, and the sample size is small (the largest sample includes only 23 ET patients). Additionally, there was a lack of exploration on the therapeutic mechanism of cTBS for ET patients. Therefore, the investigators conducted a double-blind, randomized, sham-controlled clinical trial to evaluate the safety and efficacy of cTBS in the treatment of ET patients over both cerebellar and cortical area.
Melasma is a hyperpigmentary disorder of the skin especially of the face. Compared with normal skin, histologic features of melasma include the enhanced activity of melanocytes, higher solar elastosis in upper dermis, basement membrane disruption which promotes melanocytes and melanin into the dermis, increased vascularization, and an increased number of mast cells. 1927nm fractional laser was approved to treat melasma with no major side effects, however,hyperpigmentation and recurrence occasionally happened after laser therapy. Mast cells may paly a key role in the refractory melasma and hyperpigmentation. We hypothesized that laser treatment may stimulate the activation of pre-existing mast cell in melasma skin and promote mast cell proliferation and degranulation to release mediators such as histamine (HA). HA has been demonstrated to increase the melanin content and tyrosinase activity of melanocytes and induce melanogenesis and morphological changes by activating cAMP-PKA pathway through H2 receptors on melanocytes5. H2R antagonist(H2RA) can suppress pigmentation by reducing the increase of activated melanocytes by UVB irradiation. In the present study, the investigators speculated that H2RA can enhance the efficacy of laser treatment of melasma and block the histamine-mediated melanogenesis and dendricity to prevent postoperative hyperpigmentation. The investigators combined 1927nm fractional laser with topical famotidine for melasma as a new therapeutic strategy to treat melasma.The investigators performed a split-face, single-blinded study to evaluate the efficacy and safety of 1927nm fractional laser with topical famotidine for the treatment of facial melasma.
The study aims to examine the effectiveness of individual and family health literacy enhancement program among older persons with physical multimorbidity. Specific objectives are: 1. To compare self-management, treatment burden, and symptom burden of older persons with physical multimorbidity between before and after receiving the individual and family health literacy enhancement program. 2. To compare self-management, treatment burden, and symptom burden of older persons with physical multimorbidity between those receiving the individual and family health literacy enhancement program and those receiving usual care. Participants in the control group will receive usual care by physician and nurses during the experimental period. The usual care consists of physical examination, regular treatment protocol, patient education and telephone follow-up by community nurses. Participants in the interventional group will receive the program which is a group-based intervention developed by the researcher based on the Individual and Family Self-Management Theory (IFSMT) (self-management skills) and the principle of Medagogy (PITS model: Pathophysiology, Indications, Treatments, Specifies) to improve patients' and their families' understanding of disease-related information and self-management skills consisting of goal setting and action plan, self-monitoring, solving problems and decision-making, and emotional control.The program will be divided into 8 sessions. Each session will be lasted for 2 hours with 1 intermittent break (10 minutes), and it will be held twice a week, and the last session will be held 1 week after the 7th session. Therefore, it will last for 5 weeks in total.
