BACKGROUND:Chinese medicine therapy is effective for patients with mild-to-moderate lumbar spinal stenosis and also has a better long-term effect than surgical patients, which can enhance perioperative efficacy and prevent spinal restenosis. OBJECTIVE:To evaluate the clinical efficacy of “Tongmai songjin yigu” massage therapy on lumbar spinal stenosis. METHODS:Eighty-four patients with degenerative lumbar spinal stenosis were randomly and equaly divided into treatment group and control group. Treatment group were treated with “Tongmai songjin yigu” massage therapy; patients in the control group were treated according to the guidelines for diagnosis and treatment of common disease in orthopedics and traumatology promulgated by China Association of Chinese Medicine, once a day, continuous for 2 weeks. RESULTS AND CONCLUSION:After treatment, the visual analog scale score in the treatment group was improved significantly (P < 0.05), and there was a significant difference in the Japanese Orthopaedic Association Scores on subjective symptom and daily life between the treatment and control groups (P < 0.05). The effective rate of the treatment group was higher than that of the control group (P< 0.05). These findings indicate that “Tongmai songjin yigu” massage therapy is better than traditional massage, but clinical large-sample studies are required.

AIM: To evaluate cell proliferation, apoptosis and migration of human retinal pigment epithelial cells ( RPE) when co - cultured with human marrow mesenchymal stem cells ( hMSCs ) in condition of hypoxia and hyperglycemia so as to explore possible mechanisms of diabetes aggravating choroidal neovascularization ( CNV) preliminarily.
METHODS:Both hMSCs and RPE cells were co-cultured in a transwell system. The experiment was divided into four groups: 21% O2 with 5. 56mmol/L glucose ( control group, A ), 21% O2 with 30mmol/L glucose ( hyperglycemia and normoxia group, B ) , 5% O2 with 5.56mmol/L glucose ( normoglycemia and hypoxia group, C ) and 5% O2 with 30mmol/L glucose ( hyperglycemia and hypoxia group, D) . Cell Counting Kit-8 (CCK-8) was used to detect the proliferation of RPE cells in each group at 12, 24 and 48h respectively. Flow cytometry was performed to observe apoptosis of RPE cells at 24h. Additionally, we assessed migration
capabilities of RPE via transwell assay under the condition of hyperglycemia and hypoxia by co-culturing of hMSCs.RESULTS:In this co-culturing system, at 12, 24 and 48h, group B (1. 61±0. 41, 1. 80±0. 34;1. 91±0. 35), C (1.34±0. 46, 1. 94±0. 40, 2. 14±0. 41) and D (1. 98±0. 47, 2.26±0.42, 2. 55±0. 40) showed significantly higher proliferation rate than group A (0. 92±0. 45, 1. 27±0. 32, 1.59±0. 41, P<0. 05). The migration capabilities of RPE in group B (149. 5±9. 19), C (140±9. 90) and D (170. 5±7. 78) increased dramatically compared with group A ( 114. 5±7.78, P<0.05) at 24h, whereas there was no significant difference of apoptosis ratio among four groups (P>0. 05).
CONCLUSION:By coexistence with hMSCs, the synergy of hyperglycemia and hypoxia can improve migration and proliferation of RPE cells, and have no effect on apoptosis of RPE cells within short period.

Objective: To study the correlation between expression of oncogene C-MYC protein and gene abnormality in diffuse large B-cell lymphoma (DLBCL). Methods: The expression of C-MYC protein and gene abnormality were detected by immunohistochemistry and fluorescence in situ hybridization (FISH), respectively, in 42 cases of paraffin-embedded DLBCL. All cases were collected at Department of Pathology, Weifang People′s Hospital during January 2015 to October 2016. Results: The positive rate of C-MYC protein expression was 47.6% (20/42) and the rate of abnormal C-MYC gene by FISH was 26.2%(11/42), including translocation (23.8%, 10/42) and gene amplification (2.4%, 1/42). There was a close relationship between the protein expression and gene translocation (χ²=11.813; P=0.001) and gene translocation occurred primarily in GCB (χ²=4.029; P=0.045). Conclusion The high expression (≥40%) of C-MYC protein is associated with its gene translocation, suggesting that C-MYC protein detection can be used as a surrogate marker for C-MYC gene translocation in DLBCL.

OBJECTIVETo study the possible relationship between serum ferritin levels and susceptibility to attention deficit hyperactivity disorder (ADHD) in children.

METHODSThe papers relating to the relationship between serum ferritin levels and susceptibility to childhood ADHD were searched in the Database CBM, CNKI, VIP and PubMed. The Meta-analysis software RevMan 5.0 was used for the heterogeneity test and for the pooled OR calculation. Sensitivity and publication bias analysis were performed.

RESULTSFive control studies were included for the Meta analysis, including 258 cases of ADHD and 138 control cases. There was heterogeneity in the studies on the relationship between serum ferritin levels and susceptibility to childhood ADHD (P=0.003). So the studies were analyzed using the random-effect model. The pooled OR of serum ferritin levels and susceptibility to childhood ADHD was -23.09 (95%CI:-33.06-13.13; P<0.00001). The funnel plots did not indicate the existence of publication bias.

CONCLUSIONSThe results from present Meta analysis can prove that serum ferritin levels are associated with susceptibility to childhood ADHD.

Objective:To clarify the specificity of patient blood type and blood type antibody through patient blood type serological tests and molecular biology results,and to search for matching blood for patients.Methods:Blood type serological methods were used for the identification of red blood cell ABO,RhD,and p blood type.Salt water method,microcolumn gel method and IAT method were used for irregular antibody screening and antibody specificity identification.Forward and reverse sanger sequencing was used to amplify specifically the third exon(CDS sequence)of the A4GALT gene,identify the mutation site and genotype of the gene.Results:The patient's serological blood type was positive for type B and D,indicating a p phenotype.At the same time,anti-Tja was detected in the serum,and further sequencing of the A4GALT gene exon was performed,the homozygous mutation with G＞C occurred at base 559,and the genotype ISBT was named A4GALT*01N.10.Molecular biology verification confirmed it to be p blood group.Serological methods confirm that the patient's serum contains anti-Tja.Conclusion:The joint identification of the rare blood type—p blood type by serological and molecular biological methods is of great significance for safe clinical blood transfusion.
