Chlorogenic acid displays several important roles in the therapeutic properties of many herbs, such as antioxidant activity, antibacterial, antiviral, scavenging free radicals and exciting central nervous system. Only about one-third of chlorogenic acid was absorbed in its prototype, therefore, its gut metabolites play a more important role in the therapeutic properties of chlorogenic acid. It is necessary to consider not only the bioactivities of chlorogenic acid but also its gut metabolites. This review focuses on the potential activities and mechanisms of chlorogenic acid and its gut metabolites on central nervous system diseases.

OBJECTIVETo study the effect of arsenic trioxide (As2O3) and all-trans retinoic acid (ATRA) on human cervical carcinoma HeLa cell line.
METHODSHeLa cells were treated with As2O3 and ATRA. The cell proliferation was evaluated by MTT assay. The expressions of NDRG-1 protein and mRNA were determined by Western blot and RT-PCR analysis.
RESULTSMTT assay showed that As2O3 and ATRA inhibited the growth of human cervical carcinoma HeLa cells in vitro in a dose- and time-dependent manner. Western blot and RT-PCR techniques showed that As2O3 and ATRA down-regulated the expressions of NDRG-1 protein and mRNA (P < 0.05).
CONCLUSIONAs2O3 and ATRA can significantly inhibit the growth and proliferation of HeLa cells. The reason of these changes may be related with the down-regulation of expression of NDRG-1.

On the basis of the chromogenic reaction between Hg and CuI, a semi-quantitative solid sampling Hg analyzer comprising the catalytic furance, Hg testing tube, air pump and smart cellphone was developed. White carrier 101 was chosen as the adsorbent for CuI to react with Hg from the catalytic furnace. The established Hg analyzer can not only visually recognize the coloration when Hg exceeding the limit standard, but also semi-quantitatively detect the Hg content in cosmetics fast using a smart cellphone and RGB analysis software, after direct solid sampling introduction of cosmetics sample. The instrumental detection limit ( LOD) of mercury was 50 ng, the linearity ranged from 50 ng to 2500 ng, the linear regression coefficient ( R2) was higher than 0. 97, and the RSD of the corresponding RGB values was 6% ( n=11 ) . Nine real cosmetics samples were measured by the established method, whose relative differences of Hg contents with that by the standard method (Safety Technical Specification for Cosmetics, 2015 edition) were less than 10% . The whole analytical time can be controlled within 5 min. The established instrumental method is simple, fast, accurate and visual, and extremely suitable to fast and on-site monitoring of Hg in cosmetics samples.

Objective To assist clinical diagnosis of Demodex blepharitis and other related ocular surface disease.Methods 42 cases were collected from the patients diagnosed of blepharitis,dry eye or blepharitis related keratoconjunctivitis (BKC) from the outpatient of the First Hospital of Xi'an City from April and July 2016.The eyelashes were pulled out and detected for the Demodex under microscopy after adding a drop of ethanol.Results 30 cases in 42 patients were detected for the Demodex (the positive rate was 71 %),while only 1 case in 10 healthy volunteers was detected for the Demodex with the positive rate of 10 %.The difference between the two groups was statistically significant (x2 =10.23,P< 0.01).Conclusion There is a high incidence rate of Demodex blepharitis.The early rapid laboratory diagnosis for Demodex blepharitis should be paid attention to and reinforced,in order to guide the timely and accurate treatment and avoid the occurrence and development of the Demodex related blepharitis,dry eye,BKC or other ocular complications.

OBJECTIVEExercise induced oscillatory ventilation (EIOB) during cardiopulmonary exercise testing (CPET) is associated with severity and prognosis of disease, but clinical approach for the character of EIOB due to circulatory dysfunction are seldom reported.
METHODSThis retrospective analysis of symptom-limited maximum CPET data with an increment of 10-20 W/min in 38 patients with CHF. We calculated the duration, frequency, amplitude and other parameters of EIOB.
RESULTSThere were 31 presenting with EIOB (82%) in all patients with CHF. In EIOB group, VE amplitude were (12.4 ± 4.4)L/min (accounting for 81% ± 30% of mean) and duration were (77.0 ± 20.0)s. The number of patients whose EIOB presenting at rest, exercise, recovery stage and the whole eriod were 24, 31, 4 and 4, respectively. Except VE, there were VO2, VCO2, RER and PETO2 presenting EIOB in all 31 patients; VE/VCO2, VO2/VE and breath frequency in 29 patients; PETCO2 in 26 patients; VT and VO2/HR in 25 patients; and HR in 2 patients.
CONCLUSIONEIOB may occur in any period of CPET, mostly in severe patient with CHF, and presenting in many variables. Due to it is resulted from the circulatory dysfunction, we should call it circulatory (cardiac) oscillatory breathing abnormality.

OBJECTIVETo investigate the value of dual-source computed tomography (DSCT) angiography in the examination of congenital coronary artery anomalies.
METHODSWe retrospectively examined 2530 patients by DSCT angiography between January 2008 and September 2010. Congenital coronary artery anomalies were shown by maximum intensity projection, curved planar reconstruction, and volume rendering.
RESULTSA total of 284 segments with congenital coronary artery anomalies in 225 patients were displayed. The anomalies included those originated from the main branch of coronary artery (n=121, including 35 segments of right coronary artery with high take-off origin and 24 segments of left coronary artery, 17 segments of right coronary artery dated from left aortic sinus, 4 segments of left coronary artery dated from right aortic sinus, 2 segments of left coronary artery dated from posterior aortic sinus, 2 segments of single coronary artery, and 37 segments of para-coronary artery) , coronary artery dysplasia (n=18) , coronary artery fistula (n=9, including 4 segments of right coronary artery-right ventricle fistula, 2 segments of right coronary artery-pulmonary artery fistula, 2 segments of left coronary artery-left ventricle fistula, and 1 segments of left coronary artery-pulmonary artery fistula) , and myocardial bridge (n=136) . In addition, 818 segments of left sinuatrial nodal artery original anomalies in 1720 patients whose sinuatrial nodal artery were well shown.
CONCLUSIONDSCT can be helpful in detecting the anomalies of coronary artery.

OBJECTIVETo analyze the volatile components of YL2000 decoction, which contain four herbs: rhizome and root of the Notopterygium incisum, the root of the Angelica pubescens f. biserrata, Scutellaria baicalensis and Coptis chinensis and investigate the changes of volatile constituents from those four herbs before and after compatibility of the herbal medicines.
METHODThe volatile components of YL2000 decoction were extracted by water-steam distillation, separated and identified by GC-MS. The relative percent content of each volatile component was quantified by area normalization method. The volatile components of YL2000 decoction were compared with the composition of the volatile oil from individual herb respectively.
RESULT39 of the 146 separated constituents in volatile oil of YL2000 decoction, accounting for 85.66%, were identified and quantified. After compatibility of the herbal medicines, most volatile oil components reported by high proportion in individual herb were not detected, in the mean time, some components in volatile oil of YL2000 decoction have never been reported before in those of all four herbs.
CONCLUSIONThe changes of volatile oil from those four herbs before and after compatibility of the herbal medicines indicate that solubilization, chemical reactions and evaporation of some volatile components during decocting may induce changes of several components.
