OBJECTIVE:To study the synthesis technology of Ligustilide dipolymer (compound Ⅰ). METHODS:Using phthalic anhydride(compoundⅡ)as raw materials,sodium borohydride was reduced to phthalide(compound Ⅲ),and then syn-thesize ligustilide dipolymer after 4 steps. Ligustilide dipolymer was characterized by 1H-NMR and 13C-NMR. The synthesis technol-ogy of fifth step was optimized by orthogonal test with catalyzer,reaction temperature and reaction time as factors using yield as in-dex. The validation test was conducted. RESULTS:The optimal synthesis technology of fifth step was as follows as aluminium mu-riate of catalyzer,reaction temperature of 150 ℃,reaction time of 5 h. The average yield of validation test was 56.16%(RSD=1.23%,n=3). Total reaction yield was 24.4%,and the purity of target product was 99.4%. CONCLUSIONS:Ligustilide dipoly-mer is synthesized successfully;synthetic process is stable,and its quality is controllable.

ObjectiveTo explore the expression of miR-130b and RUNX3mRNA in human gastric carcinoma and the clinical significance. MethodsThe expression of miR-130b and RUNX3mRNA were detected by RT-PCR in 40 cases of gastric carcinoma and corresponding normal mucosa tissue. The expression of RUNX3protein was determined by immunohistochemistry SP method. ResultsThe expression of miR-130b was significantly up-regulated in gastric carcinoma than that in the adjacent normal gastric mucosa tissues (2.18 ± 3.75 ) vs.( 2.59 ± 3.45 ),P ＜ 0.05 ; The expression of RUNX3mRNA in gastric carcinoma tissues was significantly lower than that in adjacent normal gastric mucosa tissues( 8.76 ±2.82) vs.( 7.58 ± 2.87 ),P ＜ 0.05.The expression of miR-130b and RUNX3mRNA were positively correlated with lymph node metastasis and clinical stage ( P ＜ 0.05 ) ; No significant association was found between the expression and age,gender,tumor size,distant metastasis and depth of tumor invasion ( P ＞0.05 ).The expression of miR-130b was negatively correlated with RUNX3 protein expression in nuclei and cytoplasm (P ＜ 0.05 ).ConclusionsAbnormal expression of miR-130b and RUNX3mRNA correlates with prognosis of gastric carcinoma; Decreased RUNX3 protein expression may contribute to tumourigenesis.

Objective To investigate the expression of miR-21 and PDCD4mRNA in colorectal cancer and their correlation with clinicopathological characteristics,to elucidate relationship between PDCD4and miR-21 in vivo.Methods Expression of RNA (including miR-21and PDCD4mRNA) and PDCD4 protein were detected respectively by quantitative real-time reverse transcriptase-PCR and SP immunohistochemical staining in 43 cases of colorectal carcinoma and corresponding normal mucous membrane tissue.Results In colorectal carcinoma,expression of miR-21 was higher than that of the control ( P ＜ 0.05 ),and expression of PDCD4mRNA lower than the control ( P ＜ 0.05 ).Expression of miR21 was associated with lymph node metastasis and clinical stages ( Ⅰ + Ⅱ,Ⅲ + Ⅳ ) ( P ＜ 0.05 ).On the other hand,no significant differences were observed regarding sex,tumor site,size,local invasion,distant metastases,clinical stages( Ⅰ,Ⅱ ) (P ＞ 0.05 ).Expression of PDCD4mRNA was associated with local invasion,clinical stages ( Ⅰ,Ⅱ ) ( P ＜ 0.05 ).While no significant differences were found concerning sex,site,size,lymph node metastasis,distant metastases,clinical stages( Ⅰ + Ⅱ,Ⅲ + Ⅳ ) ( P ＞ 0.05 ).miR21 levels was negatively correlated with PDCD4 expression including nuclear and nuclear and cytoplasmic put together (P ＜ 0.05 ),in contrast to PDCD4mRNA and PDCD4 expression in cytoplasmic ( P ＞ 0.05 ).Conclusions ( 1 ) Abnormal expression of PDCD4 mRNA and miR-21 correlate with prognosis in colorectal cancer.(2) miR-21 suppress translation of PDCD4mRNA by binding to the 3'-untranslated region (3'-UTR)of target PDCD4mRNA.

Objective To investigate time distribution of pressure of footplate in each stage and vertical anti-force from ground of patients with knee osteoarthritis (KOA).Methods 40 KOA patients, 10 aged people, and 10 common saplings were selected to test time distribution of pressure of footplate in each stage and vertical anti-force from ground in period of monopodia support.Results To unilateral KOA patient, there was not obvious difference to be observed in initial contact phase and forefoot push off phase ( P>0.05), but there was a significant difference in forefoot contact phase and foot flat phase between health side and sick side ( P<0.001), and there was obvious difference decreased buffer time and buffer force coefficient between them ( P<0.01).Conclusion To KOA patients, the time decreases in weight-bearing phase and absorption shocks, and amortization coefficient also decreases. These indexes can be used as the walking index of functional assessment and the objective evidence of curative effect.

ObjectiveTo explore the effect of synthesized rehabilitation on detoxification addicts.Methods100 detoxification addicts were randomly divided into the rehabilitation group and control group with 50 cases in each group. Cases of the rehabilitation group were treated with "ten-step" rehabilitation treatment, but that of the control group did not. The rehabilitating treatment included cognitive psychotherapy, behavioral therapy, family treatment, social skill training and etc. The effects of two groups were evaluate with Symptom Checklist-90 (SCL-90) scale.ResultsExcept hostility, other factorial scores of the rehabilitation group including positive items, somatization, obsession, interpersonal sensitivity, depression, phobia, paranoid and psychotic factors were significantly higher than that of the control group (P<0.05～0.01).ConclusionThe synthesized rehabilitation can obviously improve the psychology of detoxification addicts.

OBJECTIVE: To detect potential variant in an ethical Han Chinese pedigree affected with breast cancer. METHODS: The proband and her relatives were subjected to next-generation sequencing using a target capture sequencing kit containing 121 cancer-related genes. Candidate variants were selected by analysis of their type, frequency in population, and segregation with the phenotype. Candidate variant was verified by Sanger sequencing and TA cloning. RESULTS: A c.2013_2014ins GT variant was detected in the BRCA1 gene among all breast cancer patients from this pedigree but not among healthy females. The variant was not recorded in the 1000 Genome Project database or the Exome Aggregation Consortium (ExAC) database. The frameshifting insertion was predicted to form an premature stop codon in gene transcript and can give rise to a truncated protein. CONCLUSION The BRCA1 c.2013_2014ins GT variant probably underlies the pathogenesis of breast cancer in this Chinese pedigree.
