ObjectiveTo systematically evaluate the safety of Tianzhi granules used in the treatment of mild-to-moderate vascular dementia. MethodA randomized, double-blind, double-simulated, positive drug/placebo parallel controlled multi-center phase Ⅳ clinical trial and an open multi-center phase Ⅳ clinical trial of Tianzhi granules in the treatment of mild-to-moderate vascular dementia were conducted. Safety data of 1 492 patients were included and analyzed according to inclusion and exclusion criteria. The main evaluation measures were the incidence rate of adverse events/adverse reactions, laboratory indicators, vital signs, and electrocardiogram (ECG) results. ResultA total of six adverse events possibly related to the test drug occurred in 520 patients of the double-blind trial, and the symptoms were all mild and recovered. The incidence of adverse events was not statistically different among Tianzhi granules, donepezil, and placebo groups. Nine adverse events possibly related to the test drug were observed in 972 patients of the open trial, and the symptoms were mild and recovered. Laboratory tests (blood routine, urine routine, liver function, kidney function, and coagulation) and vital signs were compared before treatment (baseline) and after treatment of 12 and 24 weeks, respectively. There was no statistical significance in the main indicators before and after treatment. In the double-blinded trial, there was no significant difference in safety indicators between different groups before and after treatment. The most frequent adverse reaction was gastrointestinal discomfort, with an incidence rate of 6.64‰. ConclusionAdverse reactions occasionally occur in patients using Tianzhi granules, and it is safe to use Tianzhi granules to treat mild-to-moderate vascular dementia clinically.
2.Changes of volume and dose in target volume and organ at risk for nasopharyngeal carcinoma during intensity modulated radiotherapy
Journal of International Oncology 2016;43(3):201-203
At present,intensity modulated radiation therapy has been the main treatment of nasopharyngeal carcinoma.In the course of 6-7 weeks,most physicians use the initial formulation of the radiotherapy plan.Studies have indicated that the reduction of primary tumor and lymph nodes,as well as the reduction of normal tissue and body surface profile due to the weight loss,will affect the dose distribution of the target and the organs at risk,so as to influence the therapeutic effect of some patients.Therefore,it is necessary to reset and modify the target volumes during the radiotherapy for nasopharyngeal carcinoma.

Objective To report our first clinical experience with a novel modified culotte technique for the treatment of true coronary bifurcation lesions. Methods The novel modified culotte technique (the mono-ring culotte) stenting was done in which the side branch (SB) stent was deployed firstly followed by ex vivo wiring of a most proximal cell of SB stent with the hard end of main branch (MB) wire. Secondly, the MB stent was deployed through the most proximal cell of SB stent. The procedure was ended with kissing balloon dilation. From June 2014 to March 2015, 15 patients with true coronary bifurcation lesion were treated with mono-ring culotte stenting in our center. Results The procedures were successful in all cases without procedural complication and in-hospital major adverse cardiovascular events. The procedural time was (34. 3 ± 9. 6) min, fluoroscopic time was (18. 1 ± 3. 8) min, and contrast volume was (112. 0 ± 24. 5) ml, respectively. Post-procedurally, the residual stenosis of the main and the side branch were (10. 0 ± 2. 5)% and (10. 2 ± 5. 3)% , respectively. Conclusions The mono-ring culotte stenting is safe and feasible for treatment of true coronary bifurcation lesions, and may be superior to the conventional culotte stenting.

Objective:To investigate frequency and position characteristics of the vestibular dysfunction in vestublar neuritis patients. Method:Colaric test (CT), head impulse test (HIT), cervical vestibular evoked myogenic potential (cVEMP) and ocular vestibular evoked myogenic potential (oVEMP) were applied in 43 vestublar neuritis patients to assess their vestublar dysfunction. Superior vestublar nerve (S-VN), inferior vestibular nerve (I-VN), total vestibular nerve (T-VN) and each vestibular end organ incidence rate were calculated and statistically analyzed. Result:CT incidence rate (93.0%) was statistically higher than that of HIT (72.1%) (P<0.01). Total frequency incidence rate (72.1%) was statistically higher than that of low frequency (20.9%) (P<0.01). No high frequency only case was observed. The incidence rate of S-VN only, I-VN only and T-VN was 44.2%, 4.7% and 51.2% respectively. Among them, the incidence rate of I-VN was significantly lower than the others (P<0.01). The incidence rate of vestibular end organs was 17.4% (S-SCC), 44.2% (H-SCC), 20.9% (P-SCC), 39.5% (utricule) and 26.7% (saccule) respectively. The incidence rate of H-SCC was remarkably higher than the other semicircular canals (P<0.01). The difference between utricule and saccule was not statistically significant. Conclusion:The semicricular canal dysfunction in vestibular neuritis patients mainly involves total frequency of vestibular function, low frequency is more common than high frequency. Total vestibular nerve and single S-VN are mostly involved in vestibular neuritis.

Objective:To explore the clinical value of vestibular autorotation test (VAT) in the treatment for otogenic vertigo patients. Method:One hundred and twenty-nine definite otogenic vertigo patients were included. All patients underwent the VAT and caloric test (CT). The results were analyzed statistically. Result:In VAT examination, 89 (69.0%) cases were abnormal. In CT examination, 56 (43.4%) cases were abnormal. In the contrast test of VAT and CT, VAT results were abnormal in 47 (36.4%) patients and CT results were abnormal in 14 (10.9%) patients. The number of patients whose both VAT and CT results were abnormal was 42 (32.6%). The total number of patients with various abnormal results was 103 (79.8%). According to statistical analysis, the abnormal result rate of VAT was higher than that of CT. The abnormal result rate of both VAT and CT was higher than that of each single test. There was statistic significance in the difference (χ²=1.670, P<0.05). Conclusion:For otogenic vertigo patients, their abnormal result rate of VAT is higher than that of CT. VAT and CT can be mutually complementary. The combination of VAT and CT can help to understand the function of semicircular canal in the general and provide reference for the treatment of otogenic vertigo diseases.

OBJECTIVETo investigate the application of microsurgical technique in the replantation of amputated ear.
METHODS7 cases of amputated ears were analyzed from June 2009 to April 2015 in our department. We used microsurgical technique to anastomose about five vessels and nerves. The blood supply of auricle was restored within three to six hours. All subjects underwent treatments including anti-freezing, anti-spasm and anti-infection treatment after the emergency surgery.
RESULTS7 amputated ears were all survived after replantation. The patients were followed up for one month to six months ( average for 28 months). The appearances of survived ears body were fully recovered without any significant atrophy or pigmentation. The sensory function of ears recovered to normal after 1 year.
CONCLUSIONSThe application of microsurgical technique in the replantation of amputated ear can expect the high success rate of ear replantation. However, skilled and high-quality anastomosis technique of small vascular are required.

OBJECTIVETo characterize the effect of omeprazole on the spectrum of gene expression in the cultured human umbilical vein endothelial cell (HUVEC) line (EA.hy926), and explore the underlying molecular mechanism.
METHODSAffymetrix U133 plus2.0 oligonucleotide microarray was used to detect the alteration in the gene expression profiles induced by 1×10(-5) mol/L omeprazole in HUVECs. Real-time PCR was employed to verify the results of selected differentially expressed genes, and Western blotting was performed to test the expression levels of the related proteins.
RESULTSA total of 282 genes were found to show at least 1.5-fold changes in EA.hy926 cells after treatment with omeprazole for 48 h, including 236 up-regulated and 46 down-regulated ones. These genes were involved in the regulation of transcription, inflammatory response, immune response, cell adherence, anti-apoptosis, and signal transduction.
CONCLUSIONOmeprazole modulates the function of endothelial cells by regulating the gene expression profiles of multiple pathways.

OBJECTIVETo compare the effects of clopidogrel combined with dihydropyridine calcium-channel blockers (CCBs) or non-dihydropyridine CCBs on coronary artery disease (CAD) in elderly patients.
METHODSThe study cohort was defined as all patients ≥60 years old hospitalized for CAD with the prescription of clopidogrel between January 2001 and February 2011. The primary endpoint was death of all causes, and the secondary endpoints were nonfatal myocardial infarction (MI), hospitalization for unstable angina, stroke, transient ischemic attack, or repeat revascularization (PCI or coronary artery bypass graft).
RESULTSA total of 1021 patients were enrolled, among whom 402 patients were prescribed with clopidogrel and 619 with clopidogrel combined with CCB (dihydropyridine in 547 and non-dihydropyridine in 72). In clopidogrel group and clopidogrel with CCB group, the incidence density of death was 50.55 per thousand and 42.02 per thousand, respectively. The crude RR was 0.83 (95%CI: 0.55-1.26), and the multivariable-adjusted RR was 0.47 (95%CI: 0.14-1.6), showing no statistical significance in the rate of deaths of call causes between the two groups (P>0.05); the incidence density of composite thromboembolic events showed no significant difference between the two groups, either (P>0.05). After weighting of the propensity score, the patients with clopidogrel coadministered with non-dihydropyridine CCB showed a significant increase in composite thromboembolic events than those taking dihydropyridine CCB, with a SMRW-adjusted OR of 1.97 (95%: 1.2-3.23, P=0.007). No significant difference was observed in death or composite thromboembolic events between Pgp-inhibiting CCBs and non-Pgp-inhibiting CCBs.
CONCLUSIONCompared with clopidogrel without CCB, clopidogrel with CCB does not increase the mortality or composite thromboembolic events in elderly CAD patients, but clopidogrel combined with non-dihydropyridine CCB is associated with significantly increased composite thromboembolic events in comparison with dihydropyridine CCB.
