Journal of China Medical University 2017;46(3):219-222
Objective To summarize and discuss the laboratory characteristics of children with incomplete Kawasaki disease(IKD)in recent 10 years and provide some evidence for early diagnosis. Methods A retrospective review was performed on 67 children with IKD and 67 children with respiratory tract infection(bacterial infection)from 2005 to 2015 in the First Hospital of China Medical University. Results The age of chil-dren with IKD varied from 2 months to 11.3 years,with the average age of 31 months. Totally 86.5%of the children were less than 5 years old. The male to female ratio was 2:1. The incidence of the disease in spring and summer was 72%. The incidences of the increasing of white blood cell ,C-reactive protein,alanine aminotransferase,aspartate aminotransferase,glutamyl transpeptidase,and platelet and the decreasing of hemoglobin and serum albumin were 82%,94%,27%,24%,45%,72%,61%,and 94%,respectively. Conclusion The levels of the hemoglobin(<109 g/L), serum albumin(<34 g/L),platelet(>393×109/L),C-reactive protein(>74 mg/L),alanine aminotransferase(>51 U/L),and glutamyl transpepti-dase(>43 U/L)may have a certain reference value for the early diagnosis of IKD.

Chinese Traditional and Herbal Drugs 2018;49(15):3516-3522
Objective: To investigate the potential molecular mechanism of Drynariae Rhizoma in the treatment of osteoarthritis based on network pharmacology and bioinformatics. Methods: The potential active constituents and targets of Drynariae Rhizoma were screened and predicted through the traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP). Using TTD and four other osteoarthritis related disease databases, combining the topological analysis, the specific target of Drynariae Rhizoma in the treatment of osteoarthritis was filtered. And the further possible molecular mechanism of Drynariae Rhizoma was analyzed through ClueGo method. Results: Seventy-one corresponding compounds of Drynariae Rhizoma were retrieved from TCMSP. According to the values of oral bioavailability (OB) and drug likeness (DL), 18 possible bioactive components were screened out, and 92 potential targets were obtained by using the related target prediction technique. A total of 168 known targets closely related to the development of osteoarthritis were retrieved from the disease-related databases. A total of 99 key genes were screened out through network topological analysis. The ClueGo analysis showed that the action mode of Drynariae Rhizoma in treating osteoarthritis was mainly working on 31 signaling pathways related to cell cycle, inflammation, infection and cancer etc. Conclusion: Drynariae Rhizoma has the characteristics of multisystem, multiple targets, and multicomponent in the treatment of osteoarthritis. Through analysis, the possible mechanism includes not only directly acting on proliferation, apoptosis, differentiation of cells related to bone reconstruction and regulation of the balance of bone metabolism, but also affecting and interfering the bone and cartilage microenvironment through regulating immunity, inflammation, and other systems, which is consistent with the current mechanism of osteoarthritis treatment.

Objective To detect the expression of translationally controlled tumor protein (TCTP) in squamous cell carcinoma (SCC) tissue and cell lines A431 and SCL-1,and to evaluate the effect of TCTP on apoptosis in and proliferation of SCC cells.Methods An immunohistochemical method was used to measure the expression of TCTP in tissue specimens from 65 patients with SCC.Western blot was performed to detect the expression of TCTP in A431 and SCL-1 cells.Three small interference RNAs (siRNAs) targeting the TPT1 gene were designed,synthesized,and transfected into A431 cells.Then,reverse transcription (RT)-PCR and Western blot were conducted to measure the expression of TPT1 mRNA and TCTP,respectively,methyl thiazolyl tetrazolium (MTT) assay and flow cytometry were carried out to detect cell proliferation and apoptosis,respectively.Results TCTP was overexpressed in SCC tissue specimens,and the expression level was positively correlated with the histologic grading of SCC (P < 0.05).Western blot showed that TCTP was expressed in both A431 and SCL-1 cells,and the expression was relatively high in A431 cells.The transfection efficiency of siRNAs varied from 90% to 95%.A decrease in the expression of TPT1 mRNA and TCTP was induced by the siRNAs in A375 cells (all P < 0.05).Conclusion The downregulation of TCTP expression may increase the apoptosis in and suppress the proliferation of A431 cells.

Objective: To investigate the function and mechanism of phospholipase Cγ1 (PLCγ1) in cell-matrix adhesion in colorectal cancer. Methods: Highly metastatic colorectal cancer cell line LoVo and lowly metastatic colorectal cancer cell line SW480 were subjected to cell-matrix adhesion assay. U73122 (a specific inhibitor of PLC) and pyrrolidine dithiocarbamate (PDTC) (an inhibitor of NF-κB) were used to study the effect of PLCγ1 and NF-κB on cell-matrix adhesion. Furthermore, Western blot and gel electrophoresis mobility shift assay (EMSA) were performed to detect the mechanism of PLCγ1 in colorectal cancer cell adhesion to matrix. Results: Inhibition of PLCγ1 or NF-κB resulted in reduction of cell-matrix adhesion in a dose-dependent manner in LoVo cells(P<0.05), but had no marked effect on SW480 cells. Western blot analysis showed that epidermal growth factor (EGF) stimulated the phosphorylation of PLCγ1 in LoVo. The results of EMSA indicated that inhibition of PLCγ1 signaling pathway also down-regulated the activity of NF-κB while EGF reversed the function. Conclusion:These data suggest that PLCγ1 plays a pivotal role in the EGF-induced cell-matrix adhesion of highly metastatic colorectal cancer cells and that NF-κB is also functional in this signaling pathway.

ObjectiveTo investigate the clinical efficacy of continual needle knife treatment for cervical spondylosis and whether it increases adverse reactions and the number of treatments.MethodNinety-two patients with cervical spondylosis were randomly allocated to a treatment group of 47 cases and a control group of 45 cases. The treatment group received continual needle knife therapy once every day and the control group, interrupted needle knifetherapy once 10 days.ResultThere were no statistically significant differences in the number of treatments, the total efficacy rate and postoperative adverse reactions between thetwo groups (P>0.05). There were statistically significant differences inthe treatment period and cure rate between the two groups (P<0.05). The treatment period was significantly shorter in the treatment group than in the control group(P<0.05). The cure rate was significantly higher in the treatment group than in the controlgroup(P<0.05).ConclusionContinual needle knife therapy cannot increase postoperative adverse reactions and the number of treatments. It can significantly shorten the treatment period, avoid another injury and increase the cure rate in the patients.
