Chinese Journal of Rehabilitation Theory and Practice 1998;4(2):64-66
Articulation disorders that inhibit the communicative ability in children can be classified into three types. In the past, we have done much work in dysarthria and organic articulation disorders. Now we begin to explore the treatment of functional articulation disorders. In this paper, we described 10 patients between four to ten years old with functional articulation disorders and approached from different angles. We have positive answers in definition, diagnose standard and treatment procedure. We also find that the cure effect is very good, 9 of 10 patients have regained normal communlcative ability after speech therapy of one to three months.We hope to do much more work in the etiology and incidence of functional articulation disorders of children in China in the future.

ObjectiveTo explore the effect and mechanism of Zuogui Jiangtang Tongmai prescription (ZGJTTMP) on astrocytes (ASs) injured by advanced glycation end products(AGEs) combined with oxygen-glucose deprivation (OGD). MethodCell counting kit-8 (CCK-8) was used to determine the optimal concentration of AGEs and the action time of OGD, and the optimal blood concentration of ZGJTTMP was selected for follow-up experiments. ASs were divided into normal group, model group (AGEs + OGD), ZGJTTMP group, an adenosine 5'-monophosphate-activated protein kinase (AMPK) inhibitor (Compound C) group, AMPK activator (AICAR) group, and combination group (ZGJTTMP + AICAR). The morphological changes in ASs in each group were observed under an inverted microscope. The cell survival rate in each group was detected by CCK-8. The content of interleukin-1β(IL-1β), interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α) was detected by enzyme-linked immunosorbent assay (ELISA). The number of autophagosomes in each group was counted under an electron microscope. The expression of microtubule-associated protein light chain 3 (LC3) was observed by immunofluorescence. The protein expression of LC3, p62, p-AMPK, AMPK, p-mammalian target of rapamycin (mTOR), mTOR, p-UNC-51 like kinase 1 (ULK1), and ULK1 was detected by Western blot. ResultAccording to the results of cell survival rate, 200 mg·L-1 AGEs and OGD for 6 h were selected as the optimal modeling conditions for the model group, and 5% was selected as the optimal blood concentration of ZGJTTMP. Under the inverted microscope, the cells were severely damaged after modeling, but the cell injury in the ZGJTTMP group and the Compound C group was significantly improved. As revealed by ELISA results, the content of IL-1β, IL-6, and TNF-α in the model group increased (P<0.01), and the content of inflammatory factors in the ZGJTTMP group and the Compound C group decreased (P<0.01). Under the electron microscope, the number of autophagosomes in the model group increased significantly. The immunofluorescence results showed that the expression area of LC3 increased in the model group (P<0.01), and the ZGJTTMP group and the Compound C group showed decreased number of autophagosomes and reduced expression area of LC3 (P<0.01). As demonstrated by the results of Western blot, compared with the normal group, the model group showed increased expression of LC3Ⅱ/LC3Ⅰ and p-AMPK/AMPK (P<0.01) and decreased p62, p-mTOR/mTOR, and p-ULK1/ULK1 (P<0.01). Compared with the model group, the ZGJTTMP group and the Compound C group showed decreased expression of LC3Ⅱ/LC3Ⅰ and p-AMPK/AMPK (P<0.01) and increased p62, p-mTOR/mTOR, and p-ULK1/ULK1 (P<0.01). ConclusionZGJTTMP possesses a protective effect on ASs with inflammatory injury by AGEs combined with OGD, which may be achieved by inhibiting the activation of the AMPK/mTOR/ULK1 pathway related to autophagy, thus inhibiting the overexpression of autophagy.

ObjectiveTo investigate the effects and mechanism of Zuogui Jiangtang Tongmai prescription (ZJTP) on human umbilical vein endothelial cells (HUVECs) damaged by high glucose combined with lipopolysaccharide (LPS). MethodThe survival rate of cells was determined by cell counting kit-8 (CCK-8), and the level of tumor necrosis factor-α (TNF-α) was determined by enzyme-linked immunosorbent assay (ELISA) to determine the optimal injury concentration and action time of LPS, as well as the optimal action concentration of ZJTP drug-containing serum. HUVECs were divided into a blank control group, a model group, a ZJTP drug-containing serum group, and an SCFA mixed liquid group. ELISA was used to detect the level of endothelin-1 (ET-1), nitric oxide (NO), interleukin-1β (IL-1β), interleukin-6 (IL-6), and TNF-α. Western blot was performed to detect the protein expression of G protein-coupled receptor43 (GPR43), β-suppressor protein-2 (β-arrestin-2), nuclear factor-κB suppressor α (IκBα), and nuclear factor κB p65 (NF-κB p65). The nucleation of NF-κB p65 was observed by immunofluorescence staining (IF). The role of GPR43 in the regulation of inflammatory injury was observed by means of small interfering ribonucleic acid (siRNA). The cells after intervention were divided into an empty carrier group, a ZJTP drug-containing serum group, a Si-GPR43 group, and a Si-GPR43 + ZJTP drug-containing serum group. The content of IL-1β, IL-6, and TNF-α was detected by ELISA. The protein expression of pathways was detected by Western blot. IF was used to observe the nucleation of NF-κB p65. ResultThe optimal molding condition was 1 mg·L-1 LPS for 24 h. The optimal drug intervention condition was 5% ZJTP drug-containing serum for 24 h. Compared with the blank control group, the content of ET-1 in the model group was significantly increased, and the content of NO was significantly decreased (P<0.01). The levels of inflammatory factors were significantly increased (P<0.01). The expressions of GPR43 and IκBα were significantly decreased, while the protein expressions of β-arrestin-2 and NF-κB p65 were significantly increased (P<0.01). NF-κB p65 protein was transferred from the extranuclear to the intranuclear (P<0.01). Compared with the model group, the content of ET-1 in the ZJTP drug-containing serum group was decreased, and the content of NO was increased (P<0.05). The levels of inflammatory factors decreased (P<0.05). The protein expressions of GPR43 and IκBα were increased, while the expressions of β-arrestin-2 and NF-κB p65 were decreased (P<0.05). The amount of NF-κB p65 transferred from the intranuclear to the extranuclear decreased (P<0.01). The mechanism study showed that compared with the Si-GPR43 group, the content of IL-1β, IL-6, and TNF-α were significantly decreased after treatment with ZJTP drug-containing serum (P<0.01). The protein expressions of GPR43 and IκBα were significantly increased (P<0.01), while the protein expressions of β-arrestin-2 and NF-κB p65 were significantly decreased (P<0.01). The amount of NF-κB p65 transferred from the extranuclear to the intranuclear decreased (P<0.01). ConclusionZJTP has a protective effect on HUVECs with high glucose and LPS-induced inflammatory injury, which may be related to the regulation of GPR43/β-arrestin-2/IκBα/NF-κB pathway.
