The leading cause of drug withdrawal from market and clinical trials failure is drug-induced liver injury (DILI). Varying clinical, histological and laboratory features of DILI, as well as undefined underlying mechanisms, hinder patients to be diagnosed in the early-stage of the disease and receive effective treatments. Conventional indicators, like serum transaminases and bilirubin, have inevitable limitations referring to sensitive prediction and specific detection of DILI. In order to reduce the occurrence of DILI, researchers have attempted to discover potential biomarkers with higher specificity and sensitivity from blood and urine in recent years. This article aims to review recent advances in biomarkers of DILI.

Objective:To investigate the characteristics of health-related risky behaviors in adolescents with bipolar disorder.Methods:Fifty adolescents aged 12 -18 years,fulfilled the International Statistical Classification of Diseases and Related Health Problems,Tenth Revision(ICD-10)criteria for bipolar disorder(29 in depressive state, 19 in manic state,and 2 in mixed state)and 100 healthy-matched controls were recruited.Their health-related risky behaviors were assessed using the Questionnaire for Adolescents Health-related Risky Behavior Inventory (AHRBI) and the Questionnaire for Adolescents Health-related Risky Behavior Inventory for Parent (AHRBI-P).Results:The bipolar group had higher AHRBI scores in the total scale and six subscales than controls,including Aggression and Violence (AV),Health-Compromising Behavior (HCB),Rule Breaking (RB),Unprotected Sex (US),Self-injury and Suicide (SS),and Smoking and Drinking(SD)[Total scores,55.5(38,119)vs.46(38,65);P <0.05].Besides, the scores of 26 items of bipolar group were all higher than controls(Ps <0.05).The scores in the total scale and six subscales had no difference between AHRBI and AHRBI-P.According to the partial correlation analysis (de-pressive state =0;manic state =1),the AHRBI and AHRBI-P scores of Self-injury and Suicide subscale were nega-tively associated with the episode state (r =-0.32,-0.33;Ps <0.05).The AHRBI scores of'destroy properties'which belongs to the Aggression and Violence subscale were positively associated with the episode state (r =0.32, P <0.05).Conclusion:The adolescents with bipolar disorder have more health-related risky behaviors than the healthy adolescents.The depressive patients have higher risk of suicide.While,the risky behavior of destroying properties tend to occur among the manic patients.

Objective To determine the clinical features and the factors affecting the recurrence of ovarian borderline epithelial tumors. Methods A retrospective data of 112 cases with ovarian borderline epithelial tumors admitted in General Hospital of Tianjin Medical University from 2000 to 2015 were analyzed. Results The average age was (50.59±16.90) years in 112 patients with FIGO stageⅠof 102 (91.07%) patients, stageⅡof 4 (3.57%) and stageⅢof 6 (5.36%). The serum tumor marker (CA125) was examined in 102 patients, and 27 cases with the elevated indicator (26.47%). Surgical treatment was performed in 112 patients. Younger patients were more likely to choose conservative surgery. Ninety-seven patients were followed up, and 5 of them relapsed. Non fertility preserving surgery was performed in patients with recurrence. The recurrence rates of patients with different clinical pathological factors were compared. The recurrence rate was higher in patients with micro infiltration than that of patients without micro infiltration [37.50%(3/8) vs. 2.25%(2/89), P=0.004]. And the recurrence rate was higher in patients with microemulsion type borderline serous tumor than that of patients with non-papillary tumors [40.00%(2/5)vs. 0(0/41),P=0.019]. Seven patients underwent conservative surgery had normal spontaneous pregnancy. Conclusion The fertility-sparing surgery can be used as the treatment procedures for young patients, which is safe and effective. It is necessary to be on alert of recurrence for the cases with micropapillary pattern, and microinvasive tumor.

To develop and validate a novel 6-dye STR(short tandem repeat) 25-plex DNA typing system for forensic DNA profiling and databases. In this study, a novel STR 25-plex DNA typing system that includes 24 autosomal STRs (D1S1656, D2S1338, D2S441, D3S1358, D5S818, D6S1043, D7S820, D8S1179, D10S1248, D12S391, D13S317, D16S539, D18S51, D19S433, D21S11, D22S1045, CSF1PO, FGA, Penta D, Penta E, TH01, TPOX, vWA, D11S4463) and Amelogenin was developed. Validation studies demonstrated the sensitivity, accuracy, and reproducibility of our novel STR 25-plex DNA typing system. The sensitivity of the STR 25-plex DNA typing system was demonstrated by the ability to obtain complete profiles from as little as 0.125ng of human DNA. Specificity testing was demonstrated by the lack of cross-reactivity to a variety of commonly encountered animal species and microbial pool. For stability testing, full profiles were obtained with humic acid concentration ≤60ng/μL and hematin ≤600μM. For forensic evaluation, the selected 24 autosomal STRs followed the Hardy–Weinberg equilibrium. Since 24 autosomal STRs were independent from one another, PM (Probability matching) was 3.5434×10-28, TDP (Total Probability of Discrimination Power) was 0.999999999999999999999999969863, and CEP (Cumulative probability of exclusion) was 0.99999999375. The new STR 25-plex typing system is sensitive, reproducible, and stable, therefore it is highly applicable for use in national DNA database and can help to facilitate international data sharing.

Objective To estimate the difference of PS、CBV/CBF in the evaluation pf angiogenesis and growth behavior of the C6 glioma.Methods Sixty adult Wistar rats were divided into 3 groups randomly.CT perfusion were performed at the time of 5,13,20 d after the rats were inoculated C6 glioma cells.Permeability surface(PS),cerebral blood volume(CBV),cerebral blood flow(CBF)of different part of the tumor(central part,peripheral part,adjacent part and contralateral normal parenchyma)were measured at different time.Results At the central parts of the lesions,there were obvious difference between different time of tumor growth among PS[(3.94?0.15),(8.47?0.34),(5.20?0.65)ml? 100g~(-1)?min~(-1)],CBF[(280.33?8.82),(388.33?14.00),(116.16?11.54)ml? 100g~(-1)?min~(-1)],CBV[(7.75?0.27),(12.73?0.98),(5.14?0.66)ml?100g~(-1)](F=4.421,P= 0.013;F=11.370,P=0.000;F=15.789,P=0.000).There were statistical difference of PS at the different time in both the peripheral and adjacent parts of the glioma.(F=13.567,P=0.000;F=12.470, P=0.000).No difference were detected in CBF or CBV at different time of the peripheral parts of the tumors(F=1.176,P=0.336;F=0.148,P=0.710).there were significant difference between different time of tumor growth among CBF[(175.33?12.95),(275.50?13.76),(246.33?12.81)ml? 100g~(-1)?min~(-1)],CBV[(4.15?0.47),(8.05?0.30),(7.54?0.89)ml?100g~(-1)]at the adjacent parts of the tumors(F=24.176,P=0.000;F=17.148,P=0.000;F=15.791,P=0.000). Coneluslon CBV,CBF can reflect the number and volume of the tumor vessels,while PS can directly reflect the function of the angiogenesis and the behavior of the glioma.

OBJECTIVETo investigate the clinicopathologic features, immunophenotyping, differential diagnoses and prognosis of histiocytic sarcoma (HS).

METHODSThe clinical and pathologic findings of 4 cases of HS were reviewed. The samples were used for paraffin section, HE stain, immunohistochemistry stain by EnVision method, electron microscope observation. Follow-up information was available in all patients.

RESULTSThe age of patients, 2 males and 2 females, ranged from 22 to 65 years old (median, 43.25 years). The sites of involvement included lymph node (2 cases), skin or soft tissue (1 case) and colon (1 case). The tumor cells were widespread infiltration, diffused distribution, no adhesion to each other. Tumor cells were middling and large, round, orbicular-ovate, polygon, epithelium appearance, plentiful cytoplasm and acidophilia, cystose. Nucelus was round, orbicular-ovate, dissymmetry. Nuclear chromatin was vacuole appearance, basophilia nucleolus, caryocinesia and pathological mitotic figure. Three of the cases showed conjugate nuclei, increased pleomorphism with multinucleated tumor giant cell formation. Focal cytoplasmic with foamy appearance was identified in 2 cases. One case demonstrated foci of spindly sarcomatoid appearance. Hemophagocytosis was identified in 2 cases. The tumor cells of 4 cases were often accompanied by various numbers of inflammatory cells. Immunohistochemical study showed that all cases were diffusely positive for α-1-ACT, CD68, CDl63 and lysozyme. Three of 4 cases also expressed CD45, CD45RO. The electron microscope results of 4 cases showed that the tumor cells were plentiful cytoplasm and a few cytolysosome in the cytoplasm, and no birbeck cytorrhyctes, cell-cell junction and digitation. Amongst the 4 patients with follow-up information available, three died of the disease 6-13 months after diagnosis. One patient, whose lesion was localized at the skin and soft tissue, survived at the present time.

CONCLUSIONHS was a scarce malignant tumor with mature histiocyte morphology and immunophenotype character. The diagnosis should be based on tissue morphology, immunohistochemistry and electron microscope observation to exclude other disorders.

OBJECTIVE: To establish a 15-plex rapid STR multiplex amplification system. METHODS: Fourteen auto-chromosome loci and one sex-chromosome were selected to compare the situations of allelic losses and nonspecific amplication under different conditions. FastStart Taq DNA polymerase and DNA standard sample 9947A were used during amplification and optimization process.15-plex rapid STR amplification system was achieved by performing various experiments including selection of amplification conditions and the volume of DNA polymerase, adjustment of inter-locus balance, optimization of rapid amplification, screening of reaction buffers, selection of reaction volume, and a variety of additives. RESULTS: Using 10 μL rapid PCR system, including 1 ng DNA templates, 0.4 μL polymerase and 10xFastStart high fidelity reaction buffer, a complete and well-balance DNA profile of 15 STR loci for standard genomic DNA was obtained in 32 minutes, without the allele drop-out and non-specific amplicons. Meanwhile, 5% glycerinum, 0.01% gelatin, 0.05% gelatin and 5 mmol/L ammonium sulfate could be used as the reactive additive during the amplification procedure. CONCLUSION The 15-plex rapid STR multiplex amplification system can be used to decrease reaction time and enhance sample throughput.
