RESUMEN
BACKGROUND:Most scholars now believe that children with cerebral palsy who have severe spinal deformities in early childhood(<15 years of age)may have a higher risk of progression of spinal deformities,which may result from imbalances in movement due to pelvic tilt,pain,etc. OBJECTIVE:To investigate the relationship between lumbar spine development and hip joint development in children with spastic cerebral palsy. METHODS:A retrospective analysis was performed in 102 children with spastic cerebral palsy admitted at Dongzhimen Hospital Affiliated to Beijing University of Chinese Medicine from January 2014 to December 2021.All admitted children had X-rays of the pelvic position and the lumbar lateral position.Anteroposterior X-ray of the pelvis was performed to measure femoral head migration percentage,central edge angle,neck-shaft angle,and acetabular index.The sagittal Cobb angle,sacral slope,arch-top distance,and lumbar lordosis index were measured by the lateral X-ray of the lumbar spine.Correlation of the two sets of indicators was further analyzed.All children were divided into normal group,risk group,hip subluxation group and total hip dislocation group according to their femoral head migration percentage,and the differences in lumbar spine indexes between groups were evaluated. RESULTS AND CONCLUSION:Pearson correlation analysis showed that the femoral head migration percentage was moderately positively correlated with sagittal Cobb angle and arch-top distance,and weakly positively correlated with lumbar lordosis index;the central edge angle was moderately negatively correlated with the arch-top distance and weakly negatively correlated with the sagittal Cobb angle;the neck-shaft angle was weakly positively correlated or not correlated with the sagittal Cobb angle and lumbar lordosis index;and the acetabular index was weakly positively correlated with the sagittal Cobb angle and arch-top distance.No statistically significant correlation was found between the remaining indicators.According to the femoral head migration percentage,the children were divided into four groups,including 25 cases in the normal group,41 cases in the risk group,27 cases in the hip subluxation group,and 9 cases in the total hip dislocation group.The sagittal Cobb angle was significantly increased in the risk group,the hip subluxation group and the total hip dislocation group compared with the normal group,showing an increasing trend group by group,and there were significant differences between groups(P<0.05).Compared with the normal group,the lumbar lordosis index in the risk group and the hip subluxation group increased significantly,and there were significant differences between groups(P<0.05).There was an increase trend in the lumbar lordosis index of the total hip dislocation group compared with the normal group.Compared with the normal group,the arch-top distance in the hip subluxation group and the total hip dislocation group increased significantly(P<0.05),and there was a stepwise increasing trend.There was no significant difference in sacral slope between groups.To conclude,the development of the lumbar spine in children with cerebral palsy is closely related to the development of the pelvic hip joint,and the most obvious relationship is between lumbar lordosis and hip dislocation.
RESUMEN
ObjectiveThis study aims to investigate the therapeutic effect of Tangbikang granules（TBK） on type 2 diabetes mellitus （T2DM） complicated with non-alcoholic fatty liver disease （NAFLD） and to elucidate the underlying mechanism. MethodT2DM and NAFLD were induced in ZDF rats， which were then respectively treated （ig） with low-dose （0.625 g·kg-1）， medium-dose （1.25 g·kg-1）， and high-dose （2.5 g·kg-1） TBK for 12 weeks. Fasting blood glucose （FBG） and body mass were recorded every 4 weeks during the treatment. One week before sampling， the feed intake of rats was detected， and after 12 h night fasting， oral glucose tolerance test （OGTT） was performed. The area under the curve （AUC） was used to evaluate glucose tolerance， and the homeostatic model assessment for insulin resistance （HOMA-IR） was calculated. Blood in abdominal aorta and liver were collected for determination of blood glucose and lipid metabolism indexes： Fasting serum insulin （FINS）， serum total cholesterol （TC）， triglyceride （TG）， low density lipoprotein cholesterol （LDL-C）， high density lipoprotein cholesterol （HDL-C）， and nonesterified fatty acids （NEFA）. The liver was weighed to calculate the liver index， and the liver tissue morphology was observed and analyzed based on hematoxylin-eosin （HE） staining and periodic acid-Schiff （PAS） staining. The protein levels of insulin receptor substrate （IRS）， phosphatidylinositol 3-kinase （PI3K）， protein kinase B （Akt） and phosphorylated IRS and Akt were detected by Western blotting. All data were analyzed by SPSS 20.0. ResultThe feed intake of the model group was higher than that in the normal group （P<0.01）， and the feed intake the administration groups was lower than that in the model group （P<0.05， P<0.01）. At the 8th and 12th week， the body mass in the model group was lower than that in the normal group （P<0.01）. Compared with the model group， TBK reduced FBG in a concentration-dependent manner. The blood glucose level in OGTT and AUC in the model group were higher/larger than those in the normal group （P<0.01）. The blood glucose value in OGTT was decreased in TBK groups and the metformin group compared with that in the model group， and AUC in the administration groups was significantly different from that in the model group （P<0.01）. The serum level of FINS and HOMA-IR in the model group were higher than those in the normal group （P<0.01）， and they were lower in the TBK groups than in the model group （P<0.01）. Serum levels of TG， TC， HDL-C， NEFA （P<0.05， P<0.01）， and LDL-C were higher in the model group than in the normal group. Serum levels of TG， TC， LDL-C， and NEFA in the TBK groups were lower than those in the model group， and the levels of TG， LDL-C， and NEFA in TBK groups were concentration-dependent （lowest levels in high-dose TBK group）. Compared with the model group， high-dose TBK significantly increased the level of HDL-C （P<0.05）. Liver index of the model group was higher than that in the normal group （P<0.01）. The liver index of the administration groups showed a decreasing trend with no significant difference from that in the model group. As for the HE staining result of liver， the model group had unclear structure of liver lobule， enlarged cells of different sizes， and obvious steatosis of hepatocytes. TBK of all doses alleviated liver injury， particularly the high dose. For the PAS staining， compared with the normal group， the model group demonstrated significant fat vacuoles and significant reduction in purplish red glycogen granules in the cytoplasm. The staining results of high- and medium-dose groups of TBK were more similar to the normal group. Western blot was used to detect the protein expression of liver tissue. The expression of PI3K protein， p-IRS1/IRS1， and p-Akt/Akt in the model group were lower than those in the normal group （P<0.01）， and they were higher in the high-dose TBK group than in the model group （P<0.01）. ConclusionTBK exerts therapeutic effect on T2DM combined with NAFLD in ZDF rats by activating the typical PI3K signaling pathway.
RESUMEN
ObjectiveTo explore the mechanism of Tangbikang granules （TBK） against diabetic peripheral neuropathy （DPN） based on network pharmacology and in-vivo experiment. MethodThe active components in medicinals of TBK and their target genes were searched from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）. The active components of the medicinals which are not included in TCMSP were searched from previous research. After the analysis of drug-likeness by SwissADME， the target genes of them were predicted with SwissTargetPrediction. DPN-related target genes were retrieved from GeneCards. The common targets of the disease and the prescription were the hub genes of TBK against DPN， which were uploaded to Metascape for Gene Ontology （GO） term enrichment and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis. High-sugar and high-fat diet and low-dose streptozotocin （STZ， ip） were employed to induce diabetes in rats， and then the model rats were respectively treated with low-dose （0.625 g·kg-1）， medium-dose （1.25 g·kg-1）， and high-dose （2.5 g·kg-1） TBK for 12 weeks. Sensory nerve conduction velocity （SNCV） was evaluated. After hematoxylin and eosin （HE） staining， the sciatic nerve was observed under light microscope to examine the nerve damage. Real-time PCR was performed to detect the gene expression of adenosine monophosphate-activated protein kinase （AMPK） pathway-related targets in rat sciatic nerve， and Western blot to measure the protein expression of AMPK and phosphorylated （p）-AMPK in rat sciatic nerve. ResultThe main active components of TBK， such as quercetin， kaempferol， β-sitosterol， leech pteridine A， stigmasterol， and baicalein were screened out， mainly acting on interleukin-6 （IL-6）， tumor necrosis factor （TNF）， protein kinase B （Akt）， JUN， and HSP90AA1 and signaling pathways such as AMPK， nuclear factor-κB （NF-κB）， and Janus kinase/signal transducer and activator of transcription （JAK/STAT）. Molecular docking results showed that β-sitosterol and stigmasterol had high binding affinity with IL-6， TNF， JUN， and HSP90AA1. As for the animal experiment， compared with the normal group， model group had low SNCV of sciatic nerve （P<0.01）， disordered and loose myelinated nerve fibers with axonotmesis and demyelinization， low mRNA expression of AMPKα， AMPKβ， peroxisome proliferator-activated receptor γ coactivator-1α （PGC-1α）， Sirtuin 3 （SirT3）， mitochondrial transcription factor A （TFAM）， and low p-AMPK/AMPK ratio in sciatic nerve （P<0.05， P<0.01）. Compared with the model group， TBK of the three doses raised the SNCV （P<0.01）， restored nerve morphology and nerve compactness， and increased the mRNA expression of AMPKα， AMPKβ， PGC-1α， SirT3， and TFAM （P<0.05， P<0.01）. The ratio of p-AMPK/AMPK in the high-dose and medium-dose TBK groups was higher than that in the model group （P<0.01）， while the protein expression in the low-dose TBK group was insignificantly different from that in the model group. ConclusionTBK exerts therapeutic effect on DPN through multiple pathways and targets. The mechanism is that it activates and regulates AMPK/PGC-1α/SirT3 signaling， which lays a basis for further study of TBK in the treatment of DPN.
RESUMEN
ObjectiveTo explore the effect of Tangbikang granules （TBK） on sciatic nerve inflammation in diabetic rats through modulation of adenosine monophosphate-activated protein kinase （AMPK）/nuclear factor （NF）-κB pathway. MethodSD rats were fed with high-fat and high-sugar diet for 8 weeks and then treated with streptozotocin （STZ， ip） at 35 mg·kg-1 for modeling. Then the rats were randomized into diabetes group， low-dose （0.625 g·kg-1）， medium-dose （1.25 g·kg-1）， and high-dose （2.5 g·kg-1） TBK groups， and lipoic acid group （0.026 8 g·kg-1） according to body weight and blood glucose level， and a normal group was designed. After modeling， administration began and lasted 12 weeks. The body mass， blood glucose level， and thermal withdrawal latency （TWL） of the rats were detected before treatment and at the 4th， 8th， and 12th week of administration. At the 12th week， the sciatic nerve was collected for hematoxylin-eosin （HE） and Luxol fast blue （LFB） staining， and the structural changes of sciatic nerve were observed under scanning electron microscope. The levels of interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α） in sciatic nerve were measured by enzyme-linked immunosorbent assay （ELISA）， and the levels of AMPK， phosphorylated （p）-AMPK， and NF-κB proteins in the sciatic nerve were measured by Western blot. ResultThe blood glucose concentration and TWL in the model group were higher than those in the normal group at each time point （P<0.01）. The levels of IL-1β， TNF-α， and NF-κB protein in sciatic nerve in the model group were higher than those in the normal group （P<0.01）， and the p-AMPK/AMPK ratio was smaller than that in the normal group （P<0.01）. Compared with the model group， TBK of the three doses lowered the TWL （P<0.05， P<0.01） and the levels of IL-1β， TNF-α， and NF-κB protein in sciatic nerve of rats （P<0.05， P<0.01）， and high-dose and medium-dose TBK raised p-AMPK/AMPK （P<0.05， P<0.01）. The sciatic nerve fibers were orderly and compact with alleviation of demyelination in rats treated with TBK compared with those in the model group. ConclusionTBK improves the function of sciatic nerve and alleviates neuroinflammation in diabetic rats. The mechanism is the likelihood that it up-regulates the expression of AMPK in the AMPK/NF-κB pathway and inhibits the expression of downstream NF-κB， thereby alleviating the neuroinflammation caused by high levels of inflammatory factors such as IL-1β and TNF-α due to NF-κB activation.
