To analyze and compare the protective effects of active components in different ethyl acetate extracts (EAEEPs) from Eclipta prostrate, in order to study the comparison of materials bases protecting normal human bronchial epithelial (NHBE) cells. The MTT assay was taken to compare the protective effect of different EAEEPs on cigarette smoke extracts (CSE) -induced NHBE cells. The ultra-performance liquid chromatography (UPLC) was applied to analyze the content of phenolic acid, coumaric grass ether and flavonoid in EAEEPs. According to the results, all of the eight EAEEPs (0-200 mg x L(-1)) showed certain protective effect on NHBE cells, with statistical difference. Specifically, the total mass of EAEEP VII (89.15 mg x L(-1)) and EAEEP VIII (57.44 mg x L(-1)), which showed the strongest activity, was not the highest, while EAEEP III (132.25 mg x L(-1)) displayed the highest total mass. In the combination with the "component structure" theory, the analysis showed a significant difference in the mass structure among phenolic acid, coumaric grass ether and flavonoid in EAEEP VIII and EAEEP VIII, which were 1.0: 1. 0: 0.5 and 1.0: 1.9: 0.8, respectively. The results suggested a specific optimal "component structure" relationship may exist in EAEEP, which could provide reference for the material base study and quality control.

Objective To investigate the geographical distribution of excessive iodine in drinking water and to demarc aI|e the excessive iodine regions in Hebei Province.Methods In 173 counties of Hebei Province, town was surveyed as an elementary unit.Five villages were sampled according to the direction of east,west, south,north,center in every town.If the water sources were more than 5 in a village,water was sampled according to the direction ofeast,west, south,north, center, respectively;If the water sources were less than 5 in a village, all were sampled:If the village used water of cental supply,only one sample wag collected.Arsenic-cerium catalysis was used to determine the iodine concentration of drinking water.Results Two thousands and forty-nine towns were investigated and 19 352 water samples were determined in Hebei Province.One hundred and seventy- two towns were confirmed to be excessive iodine areas,where the range of water iodine Wag 0.1～2840.4μg/L The water 8amDle with 18 358 had a water iodine median less than 150.0μg/L The areas with water iodine median less than 150.0μg/L,in between 150.0μg/L and less than 300.0μg/L,and equal to or more than 300.0 μg/L accounted for 94.86%,2.92%and 2.22%,respectively.There were 110 towns with water iodine median being between 150.0μg/L and iess than 300.0 μg/L and 62 towns with water iodine median equal to or more than 300 gμ/L.Exeessive iodine towns distributed in 33 counties of 6 cities involving 5 854 960 residents in'Hebei Provmce. MOBt of the water sources with excessive iodine Cangzhou were deep wells and there was a positive correlation between we depth and water iodine concentration (r=0.430,P<0.01), while they were shallow wells in Handan, Xingtai.Hengshui,and no correlation was found between well depth and water iodine concentration(r=-0.060,-0.119.-0.121,P>0.05).Conclusions Six cities have excessive iodine water resotlrees in Hebei Province, mostly in Handan.xingtai,Hengshui and Cangzhou Cities,which all are low-lying land.The water with excessive iodine is hypogene,and the towns with excessive iodine water distributein patchy or spot pattern.

OBJECTIVETo investigate the prognosis of adenoid cystic carcinoma (ACC) in salivary gland and its influencing factors.

METHODSClinical and following-up data of 76 patients with ACC in salivary glands were reviewed. Major gland tumors represented 35.5% whereas minor gland tumors comprised 64.5% of the cohort, with 8 cases (10.5%) in stage I, 23 (30.3%) in stage II, 18 (23.7%) in stage III and 27(35.5%) in stage IV. Survival rates were calculated by Kaplan-Merier method. Cumulative survival curves were evaluated using the Log-rank test. Multivariate analysis was performed by Cox proportional hazard model.

RESULTSThe regional recurrence rate was 28.9% and distant metastasis rate was 21.1%. The overall 5-year survival rate, tumor-free survival rate and tumor-related survival rate were 73.7%, 61.8% and 74.9% respectively. The overall 10-year survival rate, tumor-free survival rate and tumor-related survival rate were 48.2%, 39.8% and 56.2% respectively. Univariate survival analysis showed pathological type, clinical stage and perineural invasion were relevant to the prognosis of ACC and multivariate analysis showed they were the independent prognostic factors of ACC in salivary gland.

CONCLUSIONSClinical stage, pathological type and perineural invasion were the independent prognostic factors for adenoid cystic carcinoma in salivary gland. Surgery was the first choice for the treatment of adenoid cystic carcinoma in salivary gland, and postoperative radiotherapy may prolong the tumor-free survival time of patients in stage III and IV.

INTRODUCTIONHigh levels of toxicities have been observed when docetaxel is administered at the standard dose of 75 mg/mevery 3 weeks (Q3W) in the real-world treatment of Asian patients with metastatic castrate-resistant prostate cancer (CRPC). This study aimed to evaluate the efficacy and tolerability of 2 attenuated regimens more widely used in an Asian setting to minimise toxicity - 60 mg/mQ3W and weekly docetaxel (20 mg/mto 35 mg/m).

MATERIALS AND METHODSMedical records of 89 CRPC patients between December 2003 and April 2013 were reviewed. Pairwise statistical analysis was performed, comparing efficacy and safety outcomes of 75 mg/mQ3W and weekly docetaxel with 60 mg/mQ3W. Treatment endpoints used were prostate-specific antigen (PSA) response (decrease of ≥50% from baseline), pain improvement after cycle 2, overall survival, time to disease progression and radiological response.

RESULTSPatients who received docetaxel at 75 mg/mQ3W were younger than those who received 60 mg/mQ3W (62 years and 66 years, respectively;= 0.0489). Both groups had similar response rates. Compared with patients on 60 mg/mQ3W, more patients on weekly regimens were symptomatic at baseline (63.2% and 87.5%, respectively;= 0.0173). Longer overall survival was observed in the 60 mg/mQ3W arm than the weekly docetaxel arm (16.9 months and 10.6 months, respectively;= 0.0131), though other measures of response did not differ significantly.

CONCLUSIONOur data supports the use of 60 mg/mQ3W docetaxel which has similar efficacy and an acceptable toxicity profile compared to the standard 75 mg/mQ3W regimen. Weekly docetaxel has significant palliative benefits among symptomatic patients despite lower overall survival.

OBJECTIVETo observe the impacts of doxapram on anesthetic efficacy and respiratory and circulatory functions during anesthesia with remifentanil given by target-controlled infusion (TCI) combined with propofol in painless artificial abortion.

METHODSA total of 120 ASA I women requiring voluntarily painless artificial abortion were randomized into two equal groups. One group was given remifentanil by TCI at 2 ng/ml and propofol 1mg/kg (group I), and the other given remifentanil by TCI, propofol, and doxapram 0.6 mg/kg (group II). The anesthetic efficacy and respiratory and circulatory suppression during anesthesia were observed.

RESULTSBoth of the two groups showed satisfactory anesthetic efficacy with comparable the BIS values (P>0.05). No significant difference was noted in the induction time and awaking time between the two groups (P>0.05), but group I had more serious respiratory and circulatory depression than group II (P<0.05).

CONCLUSIONDoxapram may attenuate respiratory and circulatory depression during anesthesia with remifentanil given by TCI combined with propofol in painless artificial abortion, and provide comparable anesthetic efficacy.

OBJECTIVETo develop a method performed on an oligonucleotide array for HLA-DR53 group genotyping.

METHODSAccording to the specific allelic frequency and sequence of HLA-DRB loci in Chinese Han population, HLA-DR53 group typing probes which were immobilized on a glass supports were synthesized. A pair of group-special primers labeled by the Cy5-dCTP were designed, and the primers were used in the PCR, thus the PCR products were labeled with Cy5. The labeled PCR products were hybridized with array. The signals were scanned by scanner and analyzed by image software. The typing results were confirmed by standard DNA and PCR-SSO. One hundred and eleven samples were typed by this array.

RESULTSThere were 72 HLA-DR53 group loci typed by oligonucleotide array. Among them, 34 loci were DR9, 25 were DR4, and 13 were DR7. No false positive or false negative typing results were observed. The specificity and reproducibility were 100% and the overall time of genotyping was 5 hours.

CONCLUSIONThe oligonucleotide array technique is a precise, rapid molecular method for HLA-DR53 genotyping, suited for clinical practice.

A simple and quick method is described for the determination of ferulic acid, senkyunolide I, senkyunolide H, senkyunolide A and ligustilide in rhizomes of Ligusticum chuanxiong. The 5 active ingredients in the sample was extracted using 40% ethanol and analyzed by reversed-phase high performance liquid chromatography (HPLC). Chromatography separation was performed using Agilent 1100 series HPLC system with a Symmetry C18 column and gradient elution with a mixture of three solvents : solvent A, acetonitrile, solvent B, methanol and solvent C, 1% aqueous acetic acid, 0 min to 5 min A: B: C 20: 40: 40, 5 min to 30 min A: B: C 60 to 100 : 0 : 40 to 0. The effluent was monitored using a VWD detector set at 321 nm (0-4.3 min) and 275 nm (4.31-30 min). The flow rate was set at 1 mL x min(-1) and the injection volume was 10 microL. The column temperature was maintained at 35 degrees C. The calibration curve was linear (r > or = 0.99) over the tested ranges. The average recovery was 94.44%-103.1% (n = 6). The method has been successfully applied to the analysis in different harvest periods of L. chuanxiong samples. In this paper, single-factor randomized block design to study the 5 components content of L. chuanxiong on ten collecting stages. For the L. chuanxiong collected from April 15th to May 30rd, the content of 5 ingredients increased primarily, and then decreased. Determine the appropriate harvest time has important significance to the promotion of the quality of L. chuanxiong.
