Objective To investigate the effects of total flavonoids of litchi chinensis sonn (TFL) on cell proliferation and the molecular mechanism in rat hepatic stellate cells (HSC-T6) activated by growth factor-β1 (TGF-β1). Methods HSC-T6 cells were treated by 0.25%Trypsin-EDTA and then were digested into single cell suspension by DMEM (10%FBS included), which were mixed with TGF-β1 (5μg/L). (1) MTT method was used to detect the proliferation of HSC-T6 cells. Cells were cultured in 96-well plate and were treated by different concentrations of TFL including TGF-β1 group, the control group (5‰DMSO included), and different concentrations of TFL groups (80, 160, 320, 640 and 800 mg/L TFL). Each group has three wells. The absorbance (A) value was measured by enzyme standard meter at the 490 nm wavelength after 24 h, 48 h and 72 h treatment. The cell inhibitory rate was calculated. The subsequent experimental drug concentration and drug treatment time were determined according to half inhibitory concentration (IC50). (2) The expression levels of NF-κB andα-SMA mRNA were detected by PCR (for mRNA) and Western blot assay (for protein). Cells were cultured in the 10 cm culture dish and were divided into different TGF-β1 groups, including TGF-β1 group, the control group (5‰DMSO included), and different concentrations of TFL groups (125, 250 and 500 mg/L TFL). After 48 h, related indicators were measured. Results At the same treatment time point, with the increased concentrations of TFL, A values were gradually decreased, and the cell inhibitory rates were gradually increased. There were no significant differences in the expressions of NF-κB andα-SMA mRNA between TGF-β1 group and control group. And there were no significant differences in the expressions of NF-κB andα-SMA mRNA between TFL125 group, TGF-β1 group and control group. There was a gradually decrease in the expressions of NF-κB andα-SMA mRNA and protein with the increased concentrations of TFL. Conclusion TFL can inhibit TGF-β1-induced HSC-T6 cell proliferation, which is involved in the inhibited expressions of NF-κB andα-SMA to anti-fibrotic effects in liver fibrosis.

Objective To observe the effects of total flavone from litchi chinensis sonn (TFL) on the liver function in-cluding p16 protein, pro collagen type 3 (PC3) and pro collagen typeⅠ(PCⅠ) in model rats with liver fibrosis induced by bile duct ligation. Methods Forty rats were randomly divided into four groups:sham operation (SO) group, bile duct liga-tion (BDL) group, TFL group and silibinin (SIL) group. Rats were gavaged with saline (5 mL·kg-1·d-1) in SO and BDL group, rats were gavaged with TFL (200 mL·kg-1·d-1) in TFL group and rats were gavaged with SIL (5 mL·kg-1·d-1) in SIL group for four weeks. The serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin direct (BILD) and bilirubin total (BILT) were detected in four groups. The liver tissues were stained by HE and Masson methods. The ex-pression levels of p16, PC3 and PCⅠin liver tissues were determined by Western blot assay. Results The serum levels of ALT (44.6 IU/L±8.0 IU/L), AST (103.8 IU/L±18.1 IU/L), BILD (0.76 μmol/L±0.28μmol/L) and BILT (1.48μmol/L±0.35μmol/L) were lower in SO group. There was a higher level of ALT in BDL group (147.4 IU/L±86.3 IU/L) than that of TFL group (92.9 IU/L±47.3 IU/L). The serum level of ALT was higher in AST group (362.7 IU/L±106.6 IU/L) than that of TFL group (290.1 IU/L ± 171.7 IU/L) and SIL group (250.2 IU/L ± 54.9 IU/L). The serum level of BILD was lower in BDL group (99.71μmol/L±40.87μmol/L) than that of SIL group (137.01μmol/L±38.86μmol/L). The serum levels of BILD and BILT were significantly lower in TFL group (81.48μmol/L±47.50μmol/L, 106.64μmol/L±61.04μmol/L) than those of SIL group (P<0.05). There were small amount of new bile duct and no obvious cells degeneration, small amount of infiltration of in-flammatory cells and collagen deposition in TFL group. The liver fibrosis improved significantly in TFL group than that of BDL group. There were more new bile duct in hepatic portal area in SIL group than those of TFL group. The expression levels of p16, PC3 and PCⅠwere significantly higher in BDL group than those of TFL group. The expression level of PC3 was significantly lower in BDL group than that of SIL group. The expression level of PCⅠwas significantly higher in BDL group than that of SIL group (P<0.05). There was no significant difference in the expression level of p16 between BDL group and SIL group. The expression levels of PC16 and PC3 were significantly lower in TFL group than those of SIL group (P<0.05). There was no significant difference in the ex-pression level of PCⅠbetween TFL group and SIL group. Conclusion TFL can improve the liver function in model rats with choles-tatic liver fibrosis and reduce liver fibrosis, which may be related with inhibitory effects on the expressions of p 16, PC3 and PCⅠ.

Objective To observe the effect of botulinum toxin A combined with exercise program sit-to-stand training on lower limb spasticity and balance ability in patients with stroke.Methods A total of 84 patients with stroke admitted to our hospital from Janu-ary 2020 to December 2021 were randomly divided into control group(n=42)and treatment group(n=42).The control group was trea-ted with the exercise program sit-to-stand training alone.The treatment group was treated with botulinum toxin A combined with exer-cise program start-up training.The modified Ashworth scale(MAS),Fugl-Meyer assessment(FMA),Berg balance scale(BBS),Barthel index(BI),and stroke-specific quality of life(SS-QOL)were compared between the two groups before treatment,and 4,8,and 12 weeks after treatment.Results No significant difference in clinical baseline data was found between the two groups(P＞0.05).The MAS of the two groups at 4,8 and 12 weeks after treatment was significantly lower,while the FMA,BBS,BI,and SS-QOL were significantly higher than those before treatment(P＜0.05).Compared with the control group,the improvement of MAS,FMA,BBS,BI,and SS-QOL at 4,8 and 12 weeks after treatment was better than those in the control group(P＜0.05).Conclusion Botulinum toxin A combined with exercise program sit-to-stand training can significantly alleviate lower limb spasticity in patients with stroke,improve motor function and balance ability,and improve the ability of daily life and quality of life,which is worthy of clinical promotion and appli-cation.

ObjectiveTo compare the effect of proprioceptive neuromuscular training methods on pain and motor ability of knee in patients with early knee osteoarthritis (KOA) . MethodsFrom November, 2022 to May, 2023, 60 early KOA patients from Beijing Bo'ai Hospital and community were randomly divided into groups A, B and C, with 20 patients in each group. Group A received proprioceptive neuromuscular facilitation (PNF), group B received neuromuscular exercise (NEMEX), and group C received PNF and NEMEX, for six weeks. They were assessed with Visual Analogue Scale for pain (VAS), angle reappearance test, difference of pre-motor reaction time (VM-VL), active range of motion (AROM) of knee flexion, 10-meter walk test (10MWT), and Knee Injury and Osteoarthritis Outcome Score (KOOS) before and after treatment. ResultsAll the indexes improved in all the groups after treatment (|t| > 2.532, P < 0.05). Among the groups, the VAS score was the least in group A, and then groups C and B; the angle reappearance error was the least in group C, and similar in groups A and B; the VM-VL was the least in groups A and C, followed by group B. ConclusionPNF, NEMEX and PNF+NEMEX can relieve the pain and improve the motor function of knee in patients with early KOA, however, PNF is the most effective on relieving pain, and PNF+NEMEX is the most effective on improving knee function.
