Our findings suggested that Tai Chi exercise could improve the balance and decrease the fall risks in patients with Parkinson's disease.

Repurposing existing drugs for cancer treatment is an effective strategy. An approved antipsychotic drug, trifluoperazine (TFP), has been reported to have potential anticancer effects against several cancer types. Here, we investigated the effect and molecular mechanism of TFP in colorectal cancer (CRC). In vitro studies showed that TFP induced G0/G1 cell cycle arrest to dramatically inhibit CRC cell proliferation through downregulating cyclin-dependent kinase (CDK) 2, CDK4, cyclin D1, and cyclin E and upregulating p27. TFP also induced apoptosis, decreased mitochondrial membrane potential, and increased reactive oxygen species levels in CRC cells, indicating that TFP induced mitochondria-mediated intrinsic apoptosis. Importantly, TFP significantly suppressed tumor growth in two CRC subcutaneous tumor models without side effects. Interestingly, TFP treatment increased the expression levels of programmed death-1 ligand 1 (PD-L1) in CRC cells and programmed death-1 (PD-1) in tumor-infiltrating CD4+ and CD8+ T cells, implying that the combination of TFP with an immune checkpoint inhibitor, such as an anti-PD-L1 or anti-PD-1 antibody, might have synergistic anticancer effects. Taken together, our study signifies that TFP is a novel treatment strategy for CRC and indicates the potential for using the combination treatment of TFP and immune checkpoint blockade to increase antitumor efficiency.

Autophagy is a process the primary role of which is to clear up damaged cellular components such as long-lived proteins and organelles, thus participating in the conservation of different cells. Osteoporosis associated with aging is characterized by consistent changes in bone metabolism with suppression of bone formation as well as increased bone resorption. In advanced age, not only bone mass but also bone strength decrease in both sexes, resulting in an increased incidence of fractures. Clinical and animal experiments reveal that age-related bone loss is associated with many factors such as accumulation of autophagy, increased levels of reactive oxygen species, sex hormone deficiency, and high levels of endogenous glucocorticoids. Available basic and clinical studies indicate that age-associated factors can regulate autophagy. Those factors play important roles in bone remodeling and contribute to decreased bone mass and bone strength with aging. In this review, we summarize the mechanisms involved in bone metabolism related to aging and autophagy, supplying a theory for therapeutic targets to rescue bone mass and bone strength in older people.

Objective The aim of the study was to assess the effects of elastic taping on pain, physical function, range of motion, and muscle strength in patients with knee osteoarthritis. Design We searched the PubMed, the Cochrane Central Register of Controlled Trials, Web of Science, Physiotherapy Evidence Database, Scopus, EMBASE, OVID, CNKI, and WANFANG to identify relevant randomized controlled trials. The primary outcome measures were pain and physical function. The secondary outcome measures were range of motion and muscle strength. Results Eleven randomized controlled trials involving 490 patients with knee osteoarthritis were included. A statistically significant difference was detected in pain (standardized mean difference = −0.78, 95% confidence interval = 1.07 to −0.50, P < 0.00001), physical function (standardized mean difference = 0.73, 95% confidence interval = −1.03 to −0.43, P < 0.00001), range of motion (mean difference = 2.04, 95% confidence interval = 0.14 to 3.94, P = 0.04), and quadriceps muscle strength (mean difference = 2.42, 95% confidence interval = 1.09 to 3.74, P = 0.0004). No significant differences were found for the hamstring muscle strength. Conclusions Elastic taping has significant effects on pain, physical function, range of motion, and quadriceps muscle strength in patients with knee osteoarthritis. The current evidence is insufficient to draw conclusions on the effects of elastic taping combined with other physiotherapy for knee osteoarthritis. Further studies are needed to investigate the long-term effects of elastic taping combined with other physiotherapy compared with elastic taping alone for knee osteoarthritis.

IntroductionTranscranial direct current stimulation (tDCS) could potentially facilitate consciousness improvement in patients with disorders of consciousness (DOC). The aim of this study was to investigate the therapeutic efficacy of tDCS on consciousness recovery for patients with DOC.MethodsEight databases were systematically searched from their inception to June 2022. Quality of included studies were assessed using PEDro score and Cochrane’s risk of bias assessment. All statistical analyses were performed using RevMan software. Seventeen studies with 618 patients were identified eligible for this study, and fifteen studies with sufficient data were pooled in the meta-analysis.ResultsThe results of meta-analysis showed a significant effect on increasing GCS scores (MD = 1.73; 95% CI, 1.28–2.18; P &lt; 0.01) and CRS-R scores (MD = 1.28; 95% CI = 0.56–2.00; P &lt; 0.01) in favor of the real stimulation group as compared to sham. The results of subgroup analysis demonstrated that only more than 20 sessions of stimulation could significantly enhance the improvement of GCS scores and the CRS-R scores. Moreover, the effect of tDCS on CRS-R score improvement was predominant in patients with minimal conscious state (MCS) (MD = 1.84; 95% CI = 0.74–2.93; P &lt; 0.01).ConclusionAnodal tDCS with sufficient stimulation doses appears to be an effective approach for patients with MCS, in terms of CRS-R scores.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/, identifier CRD42022336958.
