Shanghai Journal of Acupuncture and Moxibustion 2015;(12):1159-1161
ObjectiveTo observe the clinical efficacy of electroacupuncture at Huiyang (BL35) and Zhongliao (BL33) plus scalp acupuncture in treating female stress urinary incontinence (SUI), for providing clinical evidence in the treatment of SUI.Method Ninety eligible female SUI patients were randomized into an observation group and a control group. The observation group was intervened by electroacupuncture at Huiyang and Zhongliao plus scalp acupuncture, while the control group was asked to practice contracting anus. The urine leakage degree, residual urine volume in bladder and clinical efficacy were compared.ResultAfter treatment, there was a significant difference in comparing urine leakage degree between the two groups (P<0.05); there was a significant between-group difference in comparing the residual urine volume (P<0.05); the cured and markedly-effective rate was 62.2% in the observation group versus 35.6% in the control group, and the difference was statistically significant (P<0.05). ConclusionElectroacupuncture at Huiyang and Zhongliao plus scalp acupuncture can produce a more significant clinical efficacy compared with rehabilitation training in treating female SUI.

Objective Measuring the displacement and deformation of the fifth screw under different tensile force before or after adultal internal fixation with compressing steel plate for femoral fractuer by digital speckle correlation method.And analysis of the displacement and deformation after reducing the number of screws.Aimed at providing a theoretical basis for clinical femoral internal fixation with compressing steel plate about the number of screws. Methods Taking the antisepsis femoral specimen of grown-ups, embedding and fixing with tooth powder after removing the soft tissue, producing a fixed model in the 1/2 femur.Fixing steel plate below the lateral femur subperiosteal with five screws through the fourth floor of cortical bone on both sides of the fractures, samples were divided into 10 states, group A-J were measured by orders, under the rally of 400 N,500N , measuring the displayment of the fifth screw with CSS-44100-e-universal test machine for loading rally experiment ,and automatic data processing. Results For analysis of variance, the mean displacement measurements of the fifth screw under rally of 400N,500N, B-J group and A group have significant differences(P<0.05). The mean deformation measurements of the fifth screw under rally of 400N,500N, group A and group F-J group have significant differences(P<0.05);group A and B-E group have no significant differences.Conclusion In a certain range, the fracture displacement and the numuber of the screws show negative correlation. The screws near the fracture line for femoral compression plate internal fixation of femoral fractuer is easily broken because of the too large deformation.

BACKGROUND:Anticancer drug and organic metal complexes wil form a new structure or a change in ion concentration, thus changing both the activity and toxicity to produce a synergistic effect. OBJECTIVE:To synthesize new high-efficient and low-toxic metal-fluorouracil complexes as anticancer drugs. METHODS:Copper, zinc and iron salts and fluorouracil were used to synthesize four copper, zinc and iron-fluorouracil complexes that were [Cu(5-Fu)2Cl2], [Cu(5-Fu)2(NO3)2], [Fe(5-Fu)3]SO4 and [Zn(5-Fu)2Cl2]. Preliminary chemical structures of the four complexes were confirmed by elemental analysis and mass spectrometry. Their inhibitory activity on human cancer cells, human leukemia cellline K562 and human colon cancer cellline HCT-116, was measured by MTT colorimetric assay. RESULTS AND CONCLUSION:[Cu(5-Fu)2Cl2], [Cu(5-Fu)2(NO3)2], [Zn(5-Fu)2Cl2] and [Fe(5-Fu)3SO4] were successful y synthesized. These four complexes at a mass concentration of 0.1-100 mg/L inhibited the proliferation of K562 and HCT-116 to different extents. The IC 50 values of these four complexes on K562 and HCT-116 cells were lower than those of fluorouracil, and their cytotoxicity was 1.5-7.8 times higher than that of fluorouracil. To conclude, copper/iron/zinc-fluorouracil complexes exhibit synergic inhibitory effects on cancer cellproliferation.

Objective To investigate the correlation of the polymorphisms of angiotensin Ⅱtype 1 receptor (AT1R)gene A1166C and angiotensinogen(AGT)gene M235T and blood biochemical indicators with essential hypertension(EH)in the male of Yi nationality in Yunnan province. Methods 92 hypertensive and 70 normotensive of Yi people were recruited in Yunnan province. Their basic information and blood biochemical indicators were obtained by questionnaire and standardized physical examination. The genes polymorphisms were determined by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)technique. Results(1)For the male EH patients of Yi nationality,1166C and 235T allele frequencies were 0.038 and 0.772. No significant differences in allele frequency or genotype frequency were observed between the two groups(P > 0.05).(2)The levels of TC,LDL-C and TG in EH were significantly higher than those in controls(P < 0.05). Conclusion The AT1R A1166C and AGT M235T polymorphisms were not related to the pathogenesis of EH in the male of Yi people. However,the high levels of TC,TG and LDL-C might be the risk factors of EH.

This study aims to explore possible effect of RNA polymerase I subunit D (POLR1D) on proliferation and angiogenesis ability of colorectal cancer (CRC) cells and mechanism herein. The correlation of POLR1D and Yin Yang 1 (YY1) expressions with prognosis of CRC patients in TCGA database was analyzed. Quantitative realtime polymerase chain reaction (qRT-PCR) and Western blot were applied to detect expression levels of POLR1D and YY1 in CRC cell lines and CRC tissues. SW480 and HT-29 cells were transfected with si-POLR1D or pcDNA3.1-POLR1D to achieve POLR1D suppression or overexpression before cell migration, angiogenesis of human umbilical vein endothelial cells were assessed. Western blot was used to detect expressions of p38 MAPK signal pathway related proteins and interaction of YY1 with POLR1D was confirmed by dual luciferase reporter gene assay and chromatin immunoprecipitation (ChIP). TCGA data showed that both POLR1D and YY1 expressions were up-regulated in CRC patients. High expression of POLR1D was associated with poor prognosis of CRC patients. The results showed that POLR1D and YY1 were highly expressed in CRC cell lines. Inhibition or overexpression of POLR1D can respectively suppress or enhance proliferation and angiogenesis of CRC cells. YY1 inhibition can suppress CRC progression and deactivate p38 MAPK signal pathway, which can be counteracted by POLR1D overexpression. JASPAR predicted YY1 can bind with POLR1D promoter, which was confirmed by dual luciferase reporter gene assay and ChIP. YY1 transcription can up-regulate POLR1D expression to activate p38 MAPK signal pathway, thus promoting proliferation and angiogenesis ability of CRC cells.
