ABSTRACT

Objective To study the correlation between traditional Chinese medicine(TCM)constitution and pathogenic factors in patients with ankylosing spondylitis(AS).Methods One hundred patients of AS and their family members who had medical consultation in the Fifth Hospital of Xi'an(i.e.,Shaanxi Hospital of Integrated Traditional Chinese and Western Medicine)in August 2019 and September 2020 were selected as the study subjects.The guidelines of Classification and Determination of Traditional Chinese Medicine Constitution issued by the China Association of Chinese Medicine were adopted to determine the traditional Chinese medicine(TCM)constitution types of the study subjects.The sociodemographic information,living habits,clinical symptoms,and TCM constitution types of the AS patients and their family members were collected by means of questionnaires and clinical investigations,and then the pathogenic factors of the patients with AS were investigated.The binomial Logistic regression model was used to analyze the correlation between TCM constitution types and pathogenic factors in patients with AS.Results(1)Among the 100 AS patients,the majority of them had the biased constitutions,and the biased constitutions with the occurrence frequency in descending order were yang deficiency constitution,qi deficiency constitution,and damp-heat constitution,which accounted for 33.00%,14.00%,and 18.00%,respectively.(2)The prevalence rates of AS in the first-,second-,and third-degree relatives of AS patients were 56.25%,40.00%and 25.00%,respectively.For the positive rates of human leukocyte antigen B27(HLA-B27)in AS patients and their family members,HLA-B27 in AS patients was all positive,while the positive rates of HLA-B27 in the first-,second-,and third-degree relatives of AS patients were 44.31%,30.67%and 15.63%,respectively.(3)The results of regression analysis showed that the disease duration of AS patients was significantly correlated with qi deficiency constitution,the grading of sacroiliac arthritis was correlated with qi stagnation constitution,and age was correlated with blood stasis constitution(P<0.05 or P<0.01).The results indicated that disease duration and age were the important factors affecting the constitution types of AS patients,and disease duration was closely related to qi deficiency while age was closely related to blood stasis.Conclusion AS is a highly hereditary autoimmune disease,and its onset is associated with HLA-B27.Yang deficiency is the basic constitution type of AS,and damp-heat constitution is the main constitution type in the progression of AS(especially in the active stage of the disease).The prolongation of the disease will exacerbate the illness condition of AS and then the manifestations of qi deficiency will be more obvious.

ABSTRACT

OBJECTIVE@#To investigate the role of proline 4-hydroxylase Ⅱ (P4HA2) in the occurrence and progression of liver cancer.@*METHODS@#GEPIA and Human Protein Atlas database were used to predict the expression of P4HA2 in hepatocellular carcinoma (HCC), and K-M plotter online database was used to analyze the relationship between P4HA2 expression and the prognosis of HCC. We also examined the expressions of P4HA2 in HCC cells and normal hepatocytes using qRT-PCR and Western blotting. With lentivirus-mediated RNA interference, P4HA2 expression was knocked down in hepatoma SNU-449 and Hep-3B cells, and the changes in cell proliferation, migration and invasion were assessed using cell counting kit-8 (CCK-8) assay, colony formation test, scratch test and Transwell assay. The changes in the expressions of epithelial-mesenchymal transition (EMT) and PI3K/Akt/mTOR signal pathway-related proteins were detected using Western blotting.@*RESULTS@#Online database analysis showed that the expression of P4HA2 was significantly higher in HCC tissues than in normal liver tissues (P < 0.05). The expression levels of P4HA2 mRNA and protein were also significantly higher in HCC cell lines than in normal hepatocytes (P < 0.01). Lentivirus-mediated RNA interference of P4HA2 significantly lowered the expression levels of P4HA2 mRNA and protein in the hepatoma cells (P < 0.05) and caused obvious inhibition of cell proliferation, migration and invasion. P4HA2 knockdown significantly increased the expression of E-cadherin protein, lowered the expressions of N-cadherin and Snail, and obviously decreased the expressions of phosphorylated PI3K, AKT and mTOR (P < 0.05).@*CONCLUSION@#P4HA2 enhances the proliferation, migration, invasion, and EMT of hepatoma cells by activating the PI3K/Akt/mTOR signaling pathway to promote the occurrence and progression of liver cancer.

ABSTRACT

Objective To explore the effect of metformin on learning and memory ability and hippocampal tissue structure in mice during aging induced by D-galactose, and the possible underling mechanisms. Methods Twenty-four SPF 7-month-old female ICR mice were randomly divided into three groups. Mice of the aging group and aging+metformin group were given subcutaneous injection with D-galactose on the back to induce senescence, and given intragastric gavage with 0. 9% saline or metformin. Mice of the control group were treated with 0. 9% saline. All treatments lasted for 16 weeks. The body weight and food intake were monitored, learning and memory ability and motor function were tested by Mirros water maze and shuttle box tests, HE staining was used to observe the pathology of hippocampus in the mice, and the levels of glutathione (glutathione, GSH) in hippocampus of mice were detected by colorimetry. Results Compared with the aging group, the aging+meformin group showed diverse differences:the body weight was decreased (P < 0. 05), the escape latency and swimming distance were decreased ( P < 0. 01 or P < 0. 05 ) , the swimming time in the target quadrant was prolonged (P < 0. 05) and swimming speed was accelerated (P < 0. 05) in the Morris water maze test. The numbers of active avoidance response were markedly increased in shuttle box test ( P < 0. 05 ) . The neurons with nuclear condensation and deep staining were obviously decreased in the dentate gyrus of hippocampus, however the GSH level was significantly increased ( P < 0. 05 ) . Conclusions Metformin can delay the decline of learning and memory ability, maintain the normal structure of hippocampus during the aging process in mice, which may be related to the reduction of body weight and enhancement of antioxidant levels in the hippocampus.

ABSTRACT

BACKGROUND: T?nnis classification is commonly used to quantify the severity of developmental dysplasia of the hip (DDH), which relies on the presence of the epiphyseal ossification centre. Thereafter, a new classification system (IHDI method) has been developed by the International Hip Dysplasia Institute (IHDI). However, the pathologic morphology has not been defined based on the IHDI grade.OBJECTIVE: To analyze the correlation of the pathologic changes of the hip on MRI with IHDI classification.METHODS: Image data of 65 infants (89 hips) with DDH were analyzed retrospectively, with an average age of 20.4 months. The radiographic severity was graded by IHDI system, and the correlation between IHDI classification and pathological changes of the hip was analyzed, by observing the morphology and position of the limbus, and the cartilaginous acetabular index.RESULTS AND CONCLUSION: (1) A positive correlation was detected between severity of the IHDI grades and age at reduction (r=0.456, P < 0.001). (2) Unexpectedly, the cartilaginous femoral epiphysis still remained contacting with the acetabulum in a part of type III DDH. The cartilaginous acetabular index was significantly increased with IHDI grade increasing (P=0.028). (3) The limbus was everted in all of the type I hips; however, inverted or mixed shape accounted about 60% in the type II hips, 86% in the type III, and 97% in the type IV, respectively. (4) These results manifest that the DDH was severer, and the limbus trended to be more inverted with the increasing in IHDI grade. Moreover,understanding the correlation of the pathologic morphology with the IHDI classification is of great significance for planning an appropriate treatment scheme for DDH.

ABSTRACT

Objective: To observe the serum level of fibroblast growth factor-23 (FGF-23) in patients with end stage renal disease (ESRD) and study its association with phosphorus and vitamin D metabolism. Methods: Serum FGF-23 level was determined by enzyme-linked immunosorbent assay (ELISA) in ESRD patients undergoing haemodialysis (HD, n=50) and peritoneal dialysis (PD, n=24) and in twenty healthy controls (control group, n=20). Serum level of 1,25-(OH) 2 VitD was measured by enzyme immunoassay(EIA). Serum intact parathyroid hormone (PTH), creatinine, and calcium and phosphorus were also measured. Results: Serum FGF-23 was obviously higher in HD group([88.51 ± 35.01] ng/L vs [11.76 ± 3.63] ng/L) and PD group([87.85 ± 33.65] ng/L vs [11.76 ± 3.63] ng/L) than in control group. Moreover, the serum level of 1,25-(OH)2 VitD was lower in HD and PD groups than in control group ([19.82 ± 4.99] pmol/L vs [48.37 ± 3.47] pmol/L; [24.31 ± 7.11] pmol/ L vs [48.37 ± 3.47] pmol/L), and the level of 1,25-(OH)2 VitD was much lower in HD group than in PD group. Pearson relativity analysis showed that serum FGF-23 level was positively correlated with serum creatinine, phosphorus, intact PTH and duration of dialysis(P<0.01); and was negatively correlated with 1,25-(OH)2 VitD(P<0.01). Conclusion: Serum FGF-23 is greatly up-regulated in patients with ESRD, and the level of serum 1,25-(OH)2 VitD is down-regulated. The changes of FGF-23 is associated with serum creatinine, phosphorus, intact PTH and 1,25-(OH)2 VitD.
