Methods35 MCA moderate and severe stenosis or occlusion patients diagnosed by TCD were studied;the clinical and imaging features and infarct pattern were retrospectively analyzed. Results( 1 ) Clinical features :The clinical manifestations of 35 patients was hemiplegia symptoms,in which 16 cases(45.7％ ) involved to the face,upper and lower limb,11 cases(31.4％ ) involved to the upper and lower limb,3 cases(8.6％ ) involved to the facial and upper limb,2 cases(5.7％ ) involved only to the facial,2 cases(5.7％ ) involved to the facial and upper limb,1 cases(2.9％ ) involved only to the upper limb. (2) MRA imaging characteristics and infarct pattern: 29 cases ( 82.9％ ) of patients with stenosis or occlusion showed moderate severe stenosis,6 cases( 17.1％ ) showed MCA occlusion. 30 cases( 85.7％ ) showed ischemic infarction,in which perforating artery infarction was the most common infarct pattern of middle cerebral artery stenosis or occlusive patients( 53.3％ ) ,followed by water-shed infarct ( 26. 7) ％, pial infarct was ielatively small (20. 0％ ). ConclusionThe hemiplegia was the most common clinical symptoms in patients with MCA stenosis and occlusion, and mainly involves to the face,upper and lower limb;The perforating artery infarction was the most common infarct pattern,and its infarct mechanism was an artery-to-artery embolism or hemodynamic abnormalities.

Objective Glycodelin-A is one of glycoproteins secreted from endometrial epithelial cells , and it plays an im-portant role in embryo implantation , inhibition of reject reaction and pregnancy maintenance .Glycodelin-A will become an important potential marker in evaluating the endometrial receptivity and predicting the pregnancy outcome .The aim of this study was to investigate the correlation of glycodelin-A detected on the day of HCG and endometrial receptivity and the effects of glycodelin -A on the pregnancy outcome in the intrauterine insemination (IUI) period. Methods One hundred and seven woman patients with bilateral unobstruct-ed tubes and without endometrial lesions , endometrial polyps or intrauterine adhesions from Oct 2012 to Feb 2014 in our hospital were recruited in this study .Serum glycodelin-A in women receiving IUI on the day of HCG was measured by ELISA .Serum estradiol (E2), progesterone (P), and corpus luteum (LH) levels were measured by immunochemiluminometric assays .The condition of the endometrium was examined by transvaginalultrasonography . Results The serum glycodelin-A level on the day of HCG was higher in pregnant group [(1.47 ±0.38)ng/mL] than that in nonpregnant group ([0.62 ±0.13]ng/mL).The serum glycodelin-A level on the day of HCG was higher in endometrial thickness ≥7 mm group ([1.53 ±0.49]ng/mL) than endometrial thickness <7 mm group ([0.51 ±0.17]ng/mL). Conclusion The serum glycodelin-A level on the day of HCG may reflect endometrial receptivity to a cer-tain extent , which might have prognosis value for pregnancy following IUI .

The two verities of Crgptococcus neoforinans were first observed as well growing with brown color changes on Guizotia abyssinica seed agar(GASA)and caffeic acid commeal agar(CACA.Then,C.neoformans var.neoformans was found in 18/26 pigeon droppings by both two media.C.neoformans var.gattii was not isolated by the two media in 76 Eucalyptus camaldulensis samples.However,an,overgrowth of filamentous fungus was more frequently seen on GASA.Our results suggest that CACA be capable of selevtively isolating C.neoformans with the advantages of less interference fron the overgrowth of filamentous fungi.

Objective To explore the temporal trend of cancer death rates in different age and the influencing factors in Kunshan,Jiangsu province,1981 to 2015.Methods Data were derived from cancer rcgistry and vital registration system.The Chinese age structure in 2000 was used to calculate age-standardized death rates (ASR),and annual percentage changes (APC) and 95％ confidence interval (Cl) were used to estimate the temporal trend of cancer death rates.Difference decomposition method was applied to analyze the contribution of demographic and non-demographic factors for the change of cancer mortality.Results Between 1981 and 2015,the age standardized all cancers death rate decreased from 162.49 to 93.74 per 100,000 (APC=-l.6％,95％ CI:-1.8％--1.5％).However,the ASR for those aged 70 years or above was stable over time (APC=0.2％,95％ CI:-0.2％-0.5％),whereas aged 30-69 years was decreased from 240.01 in 1981 to 93.28 in 2015 (APC=-2.8％,95％ CI:-3.0％--2.6％).In addition,the proportion of leading cancers were changed obviously.The proportion of lung cancer increased from 1981 to 2015,while gastric cancer,liver cancer,esophageal cancer and colorectal cancer decreased.Compared with the crude cancer mortality in 1993,the effect of the demographic and non-demographic factors to the increased death rate in 2015 were 308.93％ and-208.93％,respectively.Conclusion The ASR death rate of all cancers was decreasing,and the rate in those aged 30 to 69 years decreased significantly,whereas stable in those aged 70 years or above.The effect of demographic characteristics on cancer mortality was significantly greater than that of non-demographic characteristics.

BACKGROUNDTo evaluate an enzyme linked immunospot (ELISPOT) method for testing the specific cellular immunity of patients with hepatitis B and preliminarily investigate into the difference of cellular immunity in patients with various types of hepatitis B.

METHODSThe patients with acute hepatitis B, chronic hepatitis B liver cirrhosis, healthy persons with HBV vaccine immunization, healthy persons with past HBV infection and HBV naive persons were enrolled in this study. Their peripheral blood mononuclear cells were tested by ELISPOT to determine the number of gamma-interferon secreting cells.

RESULTSThe number of gamma-interferon secreting cells was significantly different between the patients with acute hepatitis B and those with chronic hepatitis B, and between the patients with acute hepatitis B and those with liver cirrhosis (P=0.0209 and P=0.0211).

CONCLUSIONThe specific cellular immunity in the patients with hepatitis B could be evaluated by determining the number of gamma-interferon secreting cells with the method of testing their peripheral blood mononuclear cells by ELISPOT. The specific cellular immunity was stronger in the patients with acute hepatitis B than in those with chronic hepatitis B and liver cirrhosis.

AIMTo identify the main metabolites of stachydrine in rat.

METHODSThe ionization, cleavage and chromatographic characteristics of stachydrine were studied by using high-performance liquid chromatography-electrospray ionization ion trap tandem mass spectrometry (HPLC-ESI/MS) for the first time. These characteristics of stachydrine were used as the basis for the analyses of metabolites in rat urine. The 0 - 24 h urine samples of rats after ig 25 mg x kg(-1) stachydrine were collected and purified by using C10 solid-phase extraction cartridge, and then analyzed by HPLC-ESI/MS to identify stachydrine and its metabolites.

RESULTSThe parent drug (stachydrine), 6 phase I metabolites (N-demethyl, dehydrogenation, ring-oxidation) and 2 phase II metabolites (glycine conjugates of 2 ring-oxidation products) were identified existing in rat urine.

CONCLUSIONThe presented method was proved to be sensitive, rapid, high selective and specific for the identification of stachydrine and its metabolites in rat urine.

AIMTo establish a rapid and sensitive LC-MSn method for the identification of trigonelline and its main metabolites in rat urine.

METHODSAfter optimizing the detection conditions of LC-MSn chromatography and mass spectrometry using trigonelline, its ionization and cleavage in ESI-MS and ESI-MSn modes were summarized, then serving as the basis for the metabolite analysis of trigonelline in rat urine. The 0-48 h urine samples of rats were collected after iv 8 mg x kg(-1) trigonelline, then, the samples were purified through C18 solid-phase extraction cartridge. The purified samples were analyzed by LC-MSn.

RESULTSThe structures of trigonelline metabolites were elucidated according to the changes of the molecular weights of the metabolites (deltaM) and their cleavage pattern in ESI-ITMSn. As a result, two phase I metabolites and the parent drug were identified existing in rat urine, and two phase II metabolites were identified.

CONCLUSIONThe LC-MSn method is rapid and high sensitive and specific, it is suitable for the identification of trigonelline and its metabolites in rat urine.
