This study was to explore a better three-dimensional (3-D) culture method of chondrocyte. The interpenetrating network (IPN) gel beads were developed through a photo-cross linking reaction with mixed barium ions and calcium ions at the ratio of 5:5 with the methacrylic alginate (MA), which was a chemically conjugated alginate with methacrylic groups. The second generation of primary cartilage cells was encapsulated in the MA gel beads for three weeks. In the designated timing, HE stain, Alamar blue method and Scanning electron microscopic were used to determine the cartilage cells growth, proliferation and the cell distribution in the scaffolds, respectively. The expression of type II collagen was investigated by an immunohistochemistry assay and the glycosaminoglycan content was quantitatively evaluated with the spectrophotometry of 1, 9 dimethylene blue assay. Compared to the alginate control group, the deposition of glycosaminoglycan was significantly upregulated in IPN-MA gel beads with higher cell proliferation. The secretion of extracellular matrix and proliferation of chondrocyte in methacrylic alginate gel beads were higher than that in Alginate beads. Cells were able to attach, to grow well on the scaffolds under scanning electron microscopy. The result of immunohistochemistry staining of collagen type II was positive, confirming the maintenance of chondrocyte phenotype in methacrylic alginate gel beads. This study shows a great potential for three-dimensional culture of cartilage.

BACKGROUND:Abnormal gaits are very common in children with cerebral palsy, and how to improve the gait is the focus of rehabilitation therapy. OBJECTIVE:To analyze the biomechanical parameters of gaits in cerebral palsy children and to observe the effects of brace control on the exercise capacity of dyskinetic cerebral palsy children. METHODS:In this paper, we compared the biomechanical parameters of children with cerebral palsy and normal children in the initial process of walking and during walking. Biomechanical parameters in the initial process of walking include spatial and temporal parameters, kinematic and kinetic parameters of the range of motion of the knee and ankle. Biomechanical parameters during walking include spatial and temporal parameters. With the aid of hand brace, dyskinetic cerebral palsy received postural control, gait training, and sling exercise therapy for 3 months. The Gross Motor Function Measure (GMFM-88) assessment and video control were conducted for evaluation of therapeutic efficiency. RESULTS AND CONCLUSION:Biomechanical parameters in the initial process of walking showed significant differences between children with cerebral palsy and normal children except for the peak of ground reaction force at frontal axis with the right foot to start walking. Biomechanical parameters during walking showed that the stance phase and bipedal stance phase were prolonged, while the step length and stride length were shortened in the children with cerebral palsy compared with the normal children. For cerebral palsy children with brace control, the GMFM-88 scores were significantly decreased after treatment, involuntary movements were reduced shown on the video, the neck and body were stable, and life skil s were improved. Children with epilepsy and cognitive impairment or who had imaging changes in the basal ganglia showed a little improvement, and children with dance-athetoid type and dystonia type had a better progress than those with athetoid spasm.

Objective To design a mathematical calculation model for better understanding and grasping the logical problem of replacement fluid and citric acid anticoagulant infusion in continuous veno-venous hemofiltration (CVVH). Methods ① Parameter definition: A, B, and T were respectively called the main part of pre-replacement fluid, 5% sodium bicarbonate solution, and 4% sodium citrate infused before filter. And a and b were respectively called the main part of post-replacement fluid, and 5% sodium bicarbonate solution infused after filter. ② Logic conversion:The liquid in back terminal (Z) was artificially divided into two parts. One (X) was the original residual plasma after filtration. The second (Y) was the part excluding the plasma, including the left part of pre-replacement fluid with sodium citrate, and the post-replacement fluid. ③The mathematical formulas of liquid volume and electrolyte concentration at X, Y and Z in unit time were listed according to the principle of CVVH and the screening coefficient of filter for different substances. ④The calculation formulas were entered into Excel form, and a mathematical calculation model was made, and a simulation calculation with examples was carried out. Results An Excel model was established by inserting the calculation formulas of volume, electrolyte, and total calcium at X, Y and Z. And it was found that the concentration of Na+, K+, Cl-, HCO3- at Y point remained unchanged only when A, B and (or) a, b was kept in same side and proportion even with the change of blood flow and other parameters without sodium citrate as anticoagulant. Once any of the parameters (such as blood flow, replacement fluid volume, etc.) were adjusted in other infusion methods (such as different ratios, different directions of the same year, etc.), the calculation results at Y would vary, and the electrolyte concentration at Z would change accordingly. A change of dilution model or parameter would result in the change of the electrolyte concentration at Y and Z with sodium citrate as anticoagulant. The concentration of total calcium scarcely changed no matter in what model and parameters. Conclusions All kinds of infusion ways could be included in the Excel model. The infusion results of all kinds of infusion matching could be intuitively evaluated. It is helpful for the medical staff to make a logical analysis and risk prediction in CVVH.

Objective:To explore the impact of social support, self-efficacy, and neurological function on disease acceptance in stroke patients.Methods:From September 2022 to February 2023, convenience sampling was used to select 322 stroke patients from Shanghai Hospital of Traditional Chinese Medicine and Yueyang Hospital of Integrated Traditional Chinese and Western Medicine as participants. The survey was conducted using the General Information Questionnaire, Perceived Social Support Scale (PSSS), Stroke Self-Efficacy Questionnaire (SSEQ), Acceptance of Illness Scale (AIS), and National Institute of Health Stroke Scale (NIHSS) .Results:The AIS, PSSS, SSEQ, and NIHSS scores of stroke patients were (21.88±10.66), (52.64±13.80), (73.92±28.91), and (5.37±3.64), respectively. Social support of patients had a positive impact on disease acceptance ( P<0.01). Self-efficacy partially mediated the relationship between social support and disease acceptance, with indirect effects accounting for 48.84% of the total effect. The second half of the mediating effect of "social support→self-efficacy→disease acceptance" (self-efficacy→disease acceptance) was regulated by neurological function ( β=-0.020, P<0.01) . Conclusions:Medical and nursing staff can increase patients' social support, enhance their self-efficacy, and strengthen targeted interventions for patients with high levels of neurological deficits, thereby improving their disease acceptance.

Objective:To investigate whether in vitro cultured human bone marrow mesenchymal stem cells (BMSCs) express sodium taurocholate cotransporting polypeptide (NTCP), assess their susceptibility to hepatitis B virus (HBV) infection and analyze the role of NTCP during HBV infection. Methods:BMSCs were infected with HBV-positive serum under different conditions. HBV DNA load in cell culture supernatants as well as in BMSCs and the amount of hepatitis B virus surface antigen (HBsAg) and hepatitis B virus e antigen (HBeAg) in cell culture supernatants were detected. To analyze the role of NTCP, BMSCs were first transfected with small interfering RNA targeting NTCP (NTCP-siRNA) and then infected with HBV-positive serum under different conditions. Virus loads and the amount of HBsAg and HBsAg were also detected. Western blot assay was performed to measure the expression of NTCP in BMSCs in each group.Results:In vitro cultured adherent BMSCs were susceptible to HBV infection albeit with a really low efficiency, but the infection efficiency was significantly increased when infecting the BMSCs in suspension. NTCP was expressed in BMSCs and the expression could be upregulated during HBV infection, especially in BMSCs in suspension. HBV infection was blocked when BMSCs were transfected with NTCP-siRNA. Conclusions:In vitro cultured human BMSCs were susceptible to HBV infection and the expressed NTCP served as a functional receptor for HBV. Human BMSCs could be used as a highly susceptible and stable cell model that needed no molecular adjuvant modification for research on the early stages of the HBV life cycle and for development of antiviral therapy.
