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.

Background and Objectives: Real-world clinical data, outside of clinical trials and expert centers, on adverse events related to the use of SyncCardia total artificial heart (TAH) remain limited. We aim to analyze adverse events related to the use of SynCardia TAH reported to the Food and Drug Administration (FDA)’s Manufacturers and User Defined Experience (MAUDE) database. Methods: We reviewed the FDA’s MAUDE database for any adverse events involving the use of SynCardia TAH from 1/01/2012 to 9/30/2020. All the events were independently reviewed by three physicians. Results: A total of 1,512 adverse events were identified in 453 “injury and death” reports in the MAUDE database. The most common adverse events reported were infection (20.2%) and device malfunction (20.1%). These were followed by bleeding events (16.5%), respiratory failure (10.1%), cerebrovascular accident (CVA)/other neurological dysfunction (8.7%), renal dysfunction (7.5%), hepatic dysfunction (2.2%), thromboembolic events (1.8%), pericardial effusion (1.8%), and hemolysis (1%). Death was reported in 49.4% of all the reported cases (n=224/453).The most common cause of death was multiorgan failure (n=73, 32.6%), followed by CVA/other non-specific neurological dysfunction (n=44, 19.7%), sepsis (n=24, 10.7%), withdrawal of support (n=20, 8.9%), device malfunction (n=11, 4.9%), bleeding (n=7, 3.1%), respiratory failure (n=7, 3.1%), gastrointestinal disorder (n=6, 2.7%), and cardiomyopathy (n=3, 1.3%). Conclusions Infection was the most common adverse event following the implantation of TAH. Most of the deaths reported were due to multiorgan failure. Early recognition and management of any possible adverse events after the TAH implantation are essential to improve the procedural outcome and patient survival.

Objective To investigate the prognosis of adenoid cystic carcinoma (ACC) in salivary gland and its influencing factors.Methods Clinical 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.Results The 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.Conclusions Clinical 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.

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.

The effect and underlying mechanism of Bu-Shen-An-Tai recipe on ovarian apoptosis in mice with controlled ovarian hyperstimulation (COH) implantation dysfunction were studied.The COH implantation dysfunction model in mice was established by intraperitoneal injection of 7.5 IU pregnant mare's serum gonadotrophin (PMSG),followed by 7.5 IU human chorionic gonadotrophin (HCG) 48 h later.Then the female mice were mated with male at a ratio of 2:l in the same cage at 6:00 p.m.The female mice from normal group were injected intraperitoneally with normal saline and mated at the corresponding time.Day 1 of pregnancy was recorded by examining its vaginal smears at 8:00 a.m.of the next day.Fifty successfully pregnant mice were equally randomly divided into 5 groups:normal control pregnant group (NC),COH implantation dysfunction model group (COH),low dosage of Bu-Shen-An-Tai recipe group (LOW),middle dosage of Bu-Shen-An-Tai recipe group (MID) and high dosage of Bu-Shen-An-Tai recipe group (HIGH).Then from day 1,the mice in different groups were respectively intragastrically given corresponding treatments at 9:00 a.m.for 5 consecutive days.The concentrations of 17β-estradiol (E2) and progesterone (P4) were determined by radioimmunoassay (RIA).The ultrastructural changes of ovarian tissues were observed by transmission electron microscope (TEM).The histopathological changes of ovarian tissues were observed by HE staining.The number of atretic follicles and pregnant corpus luteum were also recorded.TUNEL was applied to measure apoptotic cells of ovarian tissues.Western blotting was used to detect the protein expression of apoptosis-related factors like Bax,Bcl-2 and cleaved-caspase-3 in ovarian tissue of mice.The results showed that ovarian weight,the concentrations of E2 and P4,the number of atretic follicles and pregnant corpus luteum,as well as the apoptosis of granulosa cells were significantly increased in the COH group.The ultrastructures of ovarian tissues in the COH group showed that chromatin in granulosa cells was increased,agglutinated,aggregated or crescent-shaped.The focal cavitation and the typical apoptotic bodies could be seen in granulosa cells in the late stage of apoptosis.After the treatment with different doses of Bu-Shen-An-Tai recipe,the ultrastructural changes of ovarian granulosa cells apoptosis were dramatically improved and even disappeared under TEM.Visible mitochondria and mitochondrial cristae were increased and vacuoles were significantly reduced.The lipid dropltes were shown in a circluar or oval shape.The protein expression levels of Bax and cleaved-caspase-3 were decreased,and the expression of Bcl-2 protein was increased after treatment.It was concluded that Bu-Shen-An-Tai recipe can inhibit the apoptosis of ovarian granulosa cells,probably by up-regulating the protein expression of Bcl-2 and down-regulating Bax and cleaved-caspase-3,which contributes to the formation and maintenance of ovarian corpus luteum.It's helpful to promote the embryonic implantation,to reduce embryo loss and ultimately to improve the success rate of pregnancy.
