Objective By using PEG-PLL and OPG-expressing plasmid to synthesize a nanocompound PEG-PLL-OPG (PPO), to investigate its effects on osteoblasts (OB) and arteriosclerosis (AS) in mice. Methods The incidences of osteoporosis (OP) and AS were studied in people. Collect people′s serum , and divide them into different groups According to the results of diagnosis, the patients were grouped into the groups of Control, AS, OP, and AS. PPO was used to deal with OB in different groups. The cell apoptosis, cell activity, the adhersion and calcification to scaffold PCL were determined by flow cytometry, MTT, alizarin red stain and SEM,respectively. PPO was also injected intp the ApoE-/-RANKL+/+ mice via caudal vein to demonstrate its effects on BMD and AS. Results PPO could increase the cell activity , inhibit OB apoptosis and promote cell adhersion and calcifica-tion on scaffold PCL in vitro. PPO could also decrease the area and calcification of atheromatous plaque , and in-crease the BMD of collum femoris in vivo. Conclusion PPO may be a new drug for OP and AS treatments.

Objective To explore the effect of traditional Chinese massage on upper limbs spasticity in stroke patients who accepted Botulinum toxin type A (BTX-A) injection. Methods 74 stroke patients with upper limbs spasticity were divided into treatment group (n=36)and control group (n=38). The control group received BTX-A injection, and the treatment group received massage after injection. Both groups received rehabilitation training after injection and were assessed with modified Ashworth scale, Fugl-Meyer assessment and modified Barthel index before and 2 weeks, 4 weeks, 8 weeks and 12 weeks after treatment. Results All the scores of assessments improved in both groups after treatment (P<0.001), and there was no significant difference between them (P>0.05). Conclusion Addition of traditional Chinese massage doesn't work more on spasticity of upper limbs after stroke when accepted BTX-A injection.

Due to the special physiological and pathological characteristics of gliomas, most therapeutic drugs are prevented from entering the brain. To improve the poor prognosis of existing therapies, researchers have been continuously developing non-invasive methods to overcome barriers to gliomas therapy. Although these strategies can be used clinically to overcome the blood‒brain barrier (BBB), the accurate delivery of drugs to the glioma lesions cannot be ensured. Nano-drug delivery systems (NDDS) have been widely used for precise drug delivery. In recent years, researchers have gathered their wisdom to overcome barriers, so many well-designed NDDS have performed prominently in preclinical studies. These meticulous designs mainly include cascade passing through BBB and targeting to glioma lesions, drug release in response to the glioma microenvironment, biomimetic delivery systems based on endogenous cells/extracellular vesicles/protein, and carriers created according to the active ingredients of traditional Chinese medicines. We reviewed these well-designed NDDS in detail. Furthermore, we discussed the current ongoing and completed clinical trials of NDDS for gliomas therapy, and analyzed the challenges and trends faced by clinical translation of these well-designed NDDS.
