Objective To explore the curative effect of coronary artery bypass graft (CABG) in the treatment of acute coronary syndrome (ACS).Methods Clinical data of 64 patients with ACS were retrospectively analyzed,41 patients received CABG (CABG group) and 23 patients received percutaneous coronary intervention (PCI,PCI group).Mainly cardiac events and secondary cardiac events were compared.Results The incidence rate of cadiovascular and cerebrovascular events during hospitalization in CABG group was 7.32％(3/41),in PCI group was 8.70％ (2/23),there was no significant difference (P ＞ 0.05).All patients accomplished follow-up and follow-up time was 12-48 months.The meta follow-up time in CABG group was 35.26 months,in PCI group was 33.19 months.The incidence rate of cadiovascular and cerebrovascular events during follow-up in CABG group was 19.51％ (8/41),in PCI group was 30.43％(7/23),there was no significant difference (P＞ 0.05).The incidence rate of death,myocardial infarction,cerebrovascular events,angina pectoris and total cadiovascular and cerebrovascular events between two groups had no significant difference(P＞ 0.05).Conclusions The surgery treatment in ACS is feasible,the curative effect of CABG and PCI is therapeutic equivalence.The choice of operation should be based on patients' condition and individual choice.Appropriate revascularization can get the best treatment efficiency.

Objective To investigate the effect of nursing interventions on the quality of life after radiotherapy in nasopharyngeal cancer. Methods 56 patients with nasopharyngeal cancer who received radiotherapy were randomly divided into control group and intervention group. All the patients were given conventional nursing interventions, and those in the intervention group were given accurate evaluation, enhanced psychological guide, reasonable dietary guide, and special nursing for preventing and treating complications. All the patients were evaluated by using quality of life questionnaire core 30 items(QOL-C30). Results The scores of the dimensions of somatic function,psychological function, social function and material life after interventions in the intervention group were significantly higher than those in the control group (P＜0.05 ). Conclusion Nursing interventions can improve the quality of life, and the therapy can be completed smoothly.

Objective To observe the clinical efficacy of skin needling plus flash cupping for hemifacial spasm. Method Forty patients were randomized into a treatment group and a control group, 20 in each group. For both groups, the following acupoints were selected: Baihui (GV20), Sishencong (EX-HN1), Yifeng (TE17), Xiaguan (ST7), Cuanzhu (BL2), Yangbai (GB14), Taiyang (EX-HN5), Quanliao (SI18), Jiache (ST6), Dicang (ST4), Hegu (LI4), and Waiguan (TE5). Skin needling plus flash cupping was used for the treatment group, while even reducing-reinforcing needling method was used for the control group. Seven-day treatments were considered as a treatment course, and the therapeutic efficacy was analyzed after 3 courses. Result The cure rate was 65.0%in the treatment group versus 45.0% in the control group, and the difference was statistically significant (P<0.05). Conclusion Skin needling plus flash cupping can produce a significant efficacy in treating hemifacial spasm, better than ordinary needling method.

Objective To determine the effect of NS3 and NS4A proteins of Zika virus on the neuronal migration in vivo.Methods To identify the coding sequence of NS3 and NS4A,the genome of Zika SZ01 was sequenced by rapid amplification of cDNA ends (RACE) and reverse-transcription PCR,then NS3 and NS4A was constructed in pCIG vector fused with Flag-tag to express these proteins.And then these plasmids was transfected into the embryo brain of E13.5 mice by in utero electroporation,the distribution of the cells which express these proteins in the cortex was detected by Flag,eGFP and TBR1 fluorescence in E18.5 mice through immunohistochemistry so as to assess the influence of viral proteins on the neuronal migration of mouse cortex.Results 1) Sequence results showed that the amino acid sequence of NS4A is consistent with NCBI data,while NS3 has 1 amino acid mutant.2) As the fluorescence of Flag and eGFP can co-localization,the eGFP fluorescence signal marks the cells that have expressed these virus proteins in cortex.3) TBR1 fluorescence shows the distribution of the cells that express NS4A in vivo are significantly different from pCIG control and NS3 (P＜0.001).Conclusions The NS4A protein of Zika virus may affect the neuronal migration in vivo.

Objective To investigate the association between the presence of cerebral microbleeds and chronic kidney disease in patients with ischemic stroke.Methods Patients with ischemic stroke within 1-6 months were consecutively recruited.Cranial MRI was taken within two weeks after recruitment.Cerebral microbleeds were assessed using Microbleed Anatomical Rating Scale on gradient echo MRI.Demographics including sex,age and risk factors were obtained.Chronic kidney disease was defined and classified according to National Kidney Fundation-Kidney Disease Outcome Quality Initiative Guideline.Glomerular filtration rate (GFR) was estimated by using the abbreviated Modification of Diet in Renal Disease equation.Results Of the 636 patients included,mean age was (59.8 ± 10.1) years,435 (68.4％) were male.Sixty-six had decreased estimated GFR (eGFR; ＜ 60 ml · min-1 · 1.73 m-2).Two hundred and one (31.6％) patients had cerebral microbleeds,which were most commonly located in deep or infratentorial location (133/201,66.2％).The presence of cerebral microbleeds was much higher in patients with decreased eGFR than the others (48.5％ (32/66) vs 29.6％ (169/570),x2 =9.709,P =0.002).Age,history of hypertension and decreased eGFR were associated with the presence of cerebral microbleeds in univariate analysis.In multivariate analysis,decreased eGFR was independently associated with the presence of cerebral microbleeds in deep or infratentorial location (OR =1.457,95％ CI 1.044-2.034,P =0.027),but not associated with the presence of cerebral microbleeds in pure lobe.Conclusion Impaired kidney function is associated with the presence of cerebral microbleeds in deep or infratentorial regions in patients with ischemic stroke.

Objective To investigate the incidence and risk factors of cerebral microbleeds(CMB) in ischemic stroke patients.Methods Patients with cerebral infarction for 1～6 months were recruited.Clinical data were recorded.MRI was reviewed blindly to determine the number of CMB and lacunar infarcts and the white matter lesions(WML).The independent risk factors of CMB were analyzed with the Logistic multivariable regression.Results 636 subjects were included.CMB were found in 250 cases(39.3%).The incidence of CMB in patients of ≤50,50～65 and >65 years old were 27.2%,38.1% and 47.6% respectively(P<0.05).CMB was more frequent in patients with more lacunar infarcts(P<0.05).The incidence of CMB in patients with negative,mild,moderate and severe WML were 21.9%,33.8%,46.9%and 63.1% respectively(P<0.05).Logistic regression analysis showed that history of hypertension(OR=1.523,95% CI 1.019～2.276),severity of WML(OR=1.535,95% CI 1.258～1.874) and lacunar infarcts(OR=1.517,95% CI 1.087～2.118) were the independent risk factors for presence of CMB.Conclusion CMB was frequent in ischemic stroke.The frequency of CMB increased with aging,grade of lacunar infarcts and WML.History of hypertension,severity of WML and lacunar infarcts were the independent risk factors for CMB presence.

Objective To compare two verification tools for intensity modulated radiotherapy (IM-RT) and to investigate the feasibility of a new three dimensitional verification tool. Methods Five patients receiving IMRT were randomly chosen for the quality assurance plans with MapCHECK Model 1175 (SunNu-clear, Melbourne, FL,USA) and Delta4(ScandiDos, Sweden) by using Philips Pinnacle 8.0D treatment planning system. Dose verification was measured with the Varian Clinical 23EX LA. Results The overall average percentages of pass points in DD2% DTA2 mm, DD3% DTA3 mm and DD4% DTA4 mm were 84.7%, 97. 1% and 99.3% with MapCHECK Model 1175, 86.2%, 98.2% and 99.6% with Delta4 re-spectively. The differences were statisticically significant (t = 3.94, P = 0.003 ; t = 3.17, P = 0.011 ; t = 3.05 ,P =0.014,respectively). The gantry angle was changed to zero degree with MapCHECK, but not with Delta. The effects were embodied with Delta, such as the gravity on leaf position accuracy of MLC, the treat-ment table on dose distribution and the earth magnetism on dose system. Conclusion Delta4 is an ideal verification tool for intensity modulated radiotherapy.

Objective To explore the optimal power of experimental pancreatic endoscopic ultrasonography (EUS)-guided radiofrequency ablation (RFA) therapy.Methods Six healthy live minipigs were randomly divided into two groups according to random number table,which received RFA under EUS or in laparotomy.Each pig in each group was randomly allocated to received RFA at different power (5 W,10 W,15 W).The impedance was monitored and the time for each therapy was recorded.The width diameter of coagulation necrosis from RFA was measured by EUS and gross pathology.Results RFA was completed in all pigs smoothly with stable life signs and without complications.Gross and micro pathologic observation confirmed formation of coagulation necrosis lesions.The width diameter of lesions from EUS-RFA was similar to that from surgery RFA,both having a maximum value at 10 W power (11 nun VS 10 mm).Conclusion The optimal power of experimental pancreatic EUS-RFA in pig is 10W,which should be further explored for the clinical purpose.

BACKGROUND:Wnt5a is able to inhibit canonical Wnt signaling and activate non-canonical Wnt signaling pathway. In recent years, it has been found that non-classical Wnt5a/PCP signaling pathway mediated by Wnt5a plays an important role in the process of bone marrow mesenchymal stem cel proliferation and differentiation, but the underlying mechanism is unclear.
OBJECTIVE:To summarize the progress in downstream effector molecules related to Wnt5a/PCP signaling pathway, and its roles in the chondrogenic and osteogenic differentiation of bone marrow mesenchymal stem cel s.
METHODS:A computer-based online search of CqVip, CNKI and PubMed databases between January 2000 and February 2016 was performed using the Chinese keywords of“BMSCs, Wnt signaling pathways, chondrogenic differentiation, osteogenic differentiation”and English keywords of“BMSCs, chondrogenic differentiation, osteogenic differentiation, Wnt, Fzd, Ror2, RhoA, ROCK, JNK”, respectively. Literatures related to bone marrow mesenchymal stem cel chondrogenic and osteogenic differentiation were selected. Final y, 43 eligible articles were included for analysis through excluding the old and repeated research.
RESULTS AND CONCLUSION:Wnt5a, a representative protein in non-canonical Wnt signaling pathway, paticipates in the cytoskeleton, cel migration and cel polarization and other activities by mediating its downstream signaling molecules such as Fzd, Ror, RhoA, ROCK, JNK, thereby regulating its proliferation and differentiation. But it is unclear how Wnt5a/PCP participates in the bone marrow mesenchymal stem cel chondrogenic and osteogenic differentiation and how the downstream effector molecules interact or function independently, which requires further studies.
