Objective:To explore the vailation of serum sP-selectin,sE-selectin,levels in the patients of pre-diabetic,simple type 2 diabetes mellitus (T2DM) and T2DM with coronary heartdisease(CAD).To investigate the possible mechanism that sP-selectin, sE-selectin accelerate type 2 diabetes mellitus.Methods: Level of serum sP-selectin, sE-selectin was assayed by ELISA in type 2 diabetes with or without coronary heart disease (32 and 34 cases respectively),pre-diabetic (32 cases) and control group(32 cases). Meanwhile BMI,BP,FBS,FINS,TG,CHO,HDL-C,LDL-C,HbA1C were determined in all cases as well as in control group.Results:The serum levels of sP-selectin and sE-selectin in pre-diabetic,type 2 diabetes mellitus with or without coronary heart disease groups were significantly higher than the control group ( P<0.01 ).There was significant positive correlation between serum levels of sP-selectin,sE-selectin and these items including FBG ,FINS,TG,HbA1C,HOMA-IR(P<0.01);but sE-selectin was negatively correlated with HDL-C (P<0.05).Conclusion:sP-selectin,sE-selectin,are risk factors in the initiation and progression of pre-diabetic,type 2 diabetes with or without coronary heart disease;sP-selectin and sE-selectin possibly accelerate type 2 diabetes by inducing insulin resist-ance.

Objective To explore the influence of age factor on the treatment of cutaneous hemangioma with (90Sr-90Y) applicator.Methods A total of 224 babies and children of different ages with cutaneous hemangioma were treated by using 90Sr-90 Y applicator.Then,the relation between their therapeutic effects and ages were analyzed respectively.Results The differences in the therapeutic effect between group of one month to less than one year and group of one to less than five years,and group of one month to less than one year and group of five to ten years,and between group of one to less than five ages and group of five to ten years (P＜0.05),were statistically significant.With an increase of the age,the recovery rate gradually decreased,but their effective rate,improvement rate and ineffective rate increased.In the 199 well-healed or effective patients,the differences in the distribution of treatment course between group of one month to less than one year and group of one to less than five years,and group of one month to less than one year and group of five to ten years,were statistically significant (P＜0.05); but the difference in the distribution of treatment course between group of one to less than five ages and group of five to ten years was not statistically significant (P＞0.05).The number of treatment course presented an increased tendency with an increase of the age for patients.Conclusions The age of patients is a factor influencing the therapeutic effect on cutaneous hemangioma with 90 Sr-90Y applicator.The younger the patients,the better their therapeutic effects,the shorter their courses of treatment,and the smaller the adverse reaction of beta ray.

Aim To establish a LC-MS/MS method for the determination of pirfenidone(BT)and its major metabolite 5-carboxy-pirfenidone(SBT)in human plasma.Methods Human plasma samples containing BT and SBT,as well as their corresponding deuterium-labeled internal standards pirfenidone-d5(dBT)and 5-carboxy-pirfenidone-d5(dSBT),were precipitated using methanol.Chromatographic separation was carried out on an Agilent ZORBAX SB C18(3.0 mm×100 mm,3.5 μm)column with the mobile phase of water(0.5％formic acid)and acetonitrile(50/50).The detection of analytes was performed on a tandem mass system equipped with an electrospray ionization source in positive ion mode using multiple-reaction monitoring.The MS/MS ion transitions monitored were m/z 185.958→77.1 for BT,m/z 215.944→77.0 for SBT,m/z 190.965→81.1 for dBT and m/z 220.948→99.1 for dSBT.Results There was no remarkable interference in blank solvent,plasma,and there was no mutual interference between analytes or internal standards.The proposed method showed good linearity over the concentration range of 0.020 59～25.14 mg·L-1 for BT and 0.016 73～20.42 mg·L-1 for SBT.The intra-batch and inter-batch precision and accuracy were proved to be acceptable.Human samples kept stable after 4 h at room temperature,the three freeze-thaw cycles and 10,29 and 52 days at-70 ℃,and the processed samples remained stable after 24 h in the autosampler.The average extraction recovery and matrix effect were precise,reproducible and acceptable.Conclusion Our current LC-MS/MS method is proved to be sensitive,accurate and convenient,and could be suitable for the clinical pharmacokinetic studies of BT-related preparations.

Aim To establish a LC-MS/MS method for the determination of hydroxysafflor yellow A ( QA ) in human plasma. Methods After being added into 0. 2M ammonium acetate (1∶1,V/V), QA was extrac-ted using solid-phase extraction technique, and the eluent was directly injected into LC-MS/MS systems. Agilent ZORBAX SB C18 (3. 0 × 100 mm, 3. 5 μm) column and isocratic elution system composing of meth-anol and 0. 2 mM ammonium acetate (70 ∶ 30, V/V) provided chromatographic separation of QA and internal standard isorhamnetin-3-O-neohespeidoside ( SLS) fol-lowed by detection with mass spectrometry. The mass transition ion-pair was followed as m/z 611 . 131→490. 900 for QA and m/z 623. 032→298. 800 for SLS. Results The retention time of QA and SLS was 2. 7 min and 3. 9 min respectively, with no interference in human blank plasma. The proposed method showed good linearity over the concentration range of 8. 57 ~4185 μg·L-1 for QA with a correlation coefficient≥ 0 . 9949 . The lower limit of quantitation was 8. 570 μg ·L-1 . The intra-batch and inter-batch precision and accuracy were within 7%. The average matrix effect ranged from 115. 72% to 119. 06% with RSD less than 5%. The average extraction recovery ranged from 77. 75% to 80. 76% with RSD less than 5%. Stability of human samples after 4 h at room temperature, after the three freeze-thaw cycles and after 31 days at -70℃, and post-preparative stability of the processed sam-ples after 24 h was acceptable. Plasma samples with the concentration beyond the upper quantitation limit could be accurately determined after being diluted using 6. 25 times ( V/V ) of human blank plasma. Conclusion Our current LC-MS/MS method is sensitive, accurate and convenient, and is proved to be suitable for the sys-tematic study on clinical pharmacokinetics of QA.

Aim To establish a combined method ofβ-glucuronidase hydrolysis and LC-MS-MS analysis for the determination of scutellarein in human plasma, and investigate the pharmacokinetics of scutellarin prepara-tion in healthy male volunteers. Methods Plasma samples were prepared by enzymolysis with β-glucu-ronidase and protein precipitation with methanol. The analytes scutellarein and quercetin ( IS ) were separa-ted on an Agilent ZORBAX SB C18 column ( 2. 1 mm × 150 mm, 5 μm) with the mobile phases consisting of acetonitrile, methanol and water. Multiple reaction monitoring ( MRM) on MS was used to monitor precur-sor to produce ion transitions of m/z 285. 0→136. 8 for scutellarein and m/z 301. 1→120. 8 for IS. After method validation, this method was applied to deter-mine the plasma concentration of scutellarein in 12 male volunteers following single oral administration of 120 mg scutellarin preparation. Drug And Statistic soft-ware (1. 0) was used to process data and the pharma-cokinetic parameters were calculated. Results The assay was validated with linear range of 4 . 01-513. 38μg · L-1 for scutellarein. The intra- and inter-batch precisions ( RSD%) were within 7. 22%. The absolute recoveries were more than 84. 23%. The pharmacoki-netic parameters after a single dose were as follows:Cmax (μg · L-1 ): 159. 97 ± 58. 14; AUC(0-19) (μg · L-1·h):1151. 37 ±279. 80; AUC(0-∞)(μg·L-1· h):1194. 13 ± 264. 51; Tmax ( h):6. 33 ± 1. 67; T1/2 (h):2. 83 ± 0. 60. Conclusion The assay method is proved to be sensitive, accurate and convenient. It can be successfully applied to a pharmacokinetic study of scutellarin in healthy male volunteers.

From 2006 to 2008, the susceptibility of different species of animal hosts to Campyebacter jejubni infection was observed in various areas of Jiangsu province, in which the API Campy System was used to perform the biochemical identification and the multiple PCR assay was employed to analyse the C.jejuni isolates from 3010 specimens of fouls. Cattle, pigs and monkeys, and in addition, the susceptibility of isolates to various antibiotics was also determined. In these specimens investigated 402 samples were found to be positive in the detection of C.jejuni with a positive detection rate of 13.36%. The positive detection rates in chicken, water fouls, milk cows, pigs, monkey, red crowned crane and wapiti were 15.83% (258/1630), 10.4% (52/100), 8.24% (42/510), 15.63% (25/160), 15% (15/100), 12.5% (15/80) and 0% (0/30) respectively. Meanwhile, the antibiotics to which the isolates from different hosts showed high rate of sensitivity to 27 antibiotics of 10 varieties included: chloromycetin (100%), Almocylin (99.7%), amicarcin (92.59%), cefprozil (91.67%), alchimycin (90.74%); while the antibiotics to which these isolates showed high rate of resistance were compound neoromin (99.7%), cefoperazone (99.07%), trimethoprim (97.22%), cepronatin (91.67%), cepromondo (99,07%) respectively. It is evident that the susceptibility of different hosts to C.jejuni infection and the status of drug-resistance of the isolates appear to be quite different and more complicated in Jiangsu province.

To understand the possibility of schistosomiasis transmission on the East Route Project of the South-to-North Water Diversion Project, a survey of endemic status of schistosomiasis in Weishan Lake area was conducted. A cluster sampling of 2086 boatmen were screened with DDIA Kit, and the positive ones were examined with Kato-Katz technique. Meanwhile, a questionnaire survey about schistosomiasis control was carried out to collect the data about the boatmen's general information and knowledge , attitude and practice (KAP). The results showed there were no schistosomiasis patients. However, there exist potential risk factors for schistosomiasis transmission because of the bad hygiene habits and the poor knowledge of schistosomiasis prevention in boatmen.

Objectives To evaluate the clinical features, treatment scheme and long-term outcomes of stage 1、2 childhood neuroblastoma (NB). Methods The retrospective study included 49 newly diagnosed NB stage 1、2 patients from June 1998 to December 2010. Clinical data and long-term outcomes were analyzed. Results Twenty-four patients with stage 1 NB and twenty patients with stage 2 NB were found among all 237 patients with NB enrolled in this study. The median age at diagnosis was 25 months( 2 week to 9 year old),29 males and 20 females. Thirty-one patients (63.6%) without symptoms were discovered with tumor by physical or imaging examination. Thorax and abdomen were the most common sites of primary tumor (21 and 22 cases, accounting for 42.9% and 44.9% of all patients, respectively). Forty (81.6%) NB patients had favorable pathology classification. One patient was of MYCN amplification status. Urine vanilla mandelic acid was normal in 32 (91.4%) patients, and serum lactate dehydrogenase was less than five times of the normal value in all patients. Ten NB patients were treated ac-cording to the low-risk protocol who received surgery alone.Thirty-nine patients were treated according to intermediate-risk protocol who received both surgery and chemotherapy. All the patients achieved very good partial remission (100%).The medi-an follow-up period was 60 months(22 months to148months). Nine patients were lost after a follow up of 3 months in medi-an. The 2-、3-、5-year event free survival and overall survial of all 49 patients was 100%. Conclusions The prognosis for neu-roblastoma of stage 1、2 in this study was with 100%survival, which provides opportunity for further reduction of dosage and/or duration of episodes in chemotherapy.
