ABSTRACT
The development of information technology in the medical industry is accelerating the construction of 3-level rehabilitation networks centering on community-based rehabilitation, which is based on the Internet and in combination with the Internet of things(IOT). A municipal rehabilitation hospital cooperated with the health centers of sub-district communities in the city to build a remote rehabilitation network based on IOT technology, for rehabilitation training of community stroke patients. The two sides worked out a cooperation scheme on project management, designed and built a remote community rehabilitation management model. Under the remote monitoring and equipment data IOT, the medical team of the municipal rehabilitation hospital could formulate the therapeutic plan according to the immediately obtained relevant functional evaluation data, and the medical team of the community health service center was responsible for the implementation of the plan. Fifty-three patients in the experimental group received the training of remote lower limb intelligent feedback system based on IOT together with routine rehabilitation training. After 8 weeks of treatment, the functional evaluation data of the two groups were improved in varying degrees( P< 0.05), but the improvement of the experimental group was significantly better than that of the control group( P < 0.05). Remote rehabilitation under the construction path of remote rehabilitation network based on IOT technology could significantly promote the improvement of post-functional rehabilitation of community stroke patients. This study can provide reference for the construction of three-level remote rehabilitation networks based on IOT and the implementation of home-based remote rehabilitation therapy in the future.
ABSTRACT
Objective To evaluate the clinical efficacy of berberine for the treatment of insulin resistance (IR) in women with polycystic ovary syndrome (PCOS).Methods Sixty PCOS-IR women were randomized into treatment group and control group,30 cases in each group.At the end of the trial,26 cases in the treatment group (4 cases dropped out) and 29 cases in the control group (one case dropped out) completed the trial.The treatment group was treated with berberine orally,and the control group was treated with metformin orally,the treatment for the two groups lasting 3 months.Before and after treatment,we observed the parameters of body mass index (BMI),homeostasis model of assessment for insulin resistance index (HOMA-IR),fasting plasma glucose (FPG),fasting insulin (FINS),2-hour postprandial glucose after oral glucose tolerance test (OGTT2hPG) and 2-hour postprandial insulin after OGTT (OGTT2hINS),blood lipid levels of total cholesterol (TC),triglyceride (TG),low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C),and sexual hormones of follicle-stimulating hormone (FSH),luteotropic hormone (LH),testosterone (T) and LH/FSH ratio.Results BMI,HOMA-IR,TC,TG and LDL-C of the two groups were decreased after treatment (P ＜ 0.05 or P ＜ 0.01 compared with those before treatment),but the differences between the two groups were insignificant(P ＞ 0.05).Serum levels of T and LH as well as LH/FSH ratio in the treatment group were also decreased (P ＜ 0.05 or P ＜ 0.01 compared with those before treatment and those in the control group after treatment).Conclusion Berberine can improve HOMA-IR,decrease serum sexual hormones levels,and regulate the blood metabolism in PCOS-IR women,and its effect is similar to that of metformin.
ABSTRACT
Articular cartilage is a connective tissue consisting of a specialized extracellular matrix (ECM) that dominates the bulk of its wet and dry weight. Type II collagen and aggrecan are the main ECM proteins in cartilage. However, little attention has been paid to less abundant molecular components, especially minor collagens, including type IV, VI, IX, X, XI, XII, XIII, and XIV, etc. Although accounting for only a small fraction of the mature matrix, these minor collagens not only play essential structural roles in the mechanical properties, organization, and shape of articular cartilage, but also fulfil specific biological functions. Genetic studies of these minor collagens have revealed that they are associated with multiple connective tissue diseases, especially degenerative joint disease. The progressive destruction of cartilage involves the degradation of matrix constituents including these minor collagens. The generation and release of fragmented molecules could generate novel biochemical markers with the capacity to monitor disease progression, facilitate drug development and add to the existing toolbox for in vitro studies, preclinical research and clinical trials.

AIM To investigate whether ginsenoside Rg1 can reverse chronic lead-induced impairment of long-term potentiation (LTP) in the CA1 region of rat hippocampus. METHODS Neonatal Wistar rats were exposed to lead from parturition to weaning via milk of dams whose drinking water (20 mL per day) contained 0.2% lead acetate. Field excitatory postsynaptic potentials (fEPSP) were recorded and LTP was induced in the CA1 region in rat hippocampal slices on postnatal 20-25 d. RESULTS In hippocampal slices from both control and lead-exposed rats, perfusion with ginsenoside Rg1 50 μmol·L-1 for 20 min induced enhancement of fEPSP (LTP), while the amplitude of LTP in lead-exposed rats was lower than that of controls. In hippocampal slices from chronic lead-exposed rats, LTP induced by high-frequency stimulation (HFS, 1s, 100 Hz) was significantly reduced, while perfusing with ginsenoside Rg1 (50 μmol·L-1) for 20 min increased the amplitudes of LTP induced by HFS by 47.1%. CONCLUSION Rg1 can increase basic synaptic transmission and partially reverse chronic lead-induced impairment of HFS-LTP.
