Polycyclic aromatic hydrocarbons ( PAHs) are ubiquitous environmental pollutants, whose carcinogenicity is determinated.The mechanism of their carcinogenicity: PAHs are able to combine with aryl hydrocarbon hydrocarbon receptor ( AhR ) , resulting in some toxicity and carcinogenicity.AhR is a ligand-dependent activation transcription factor, which is activated by a large variety of ligands, regulating the expression of a series of gene involved in metabolism, and participating in important biological processes, such as singal transduction, cell proliferation,differentiation and apoptosis,and so on.Besides, it's closely related with the tumor development.Thus, it will provide a new approach for cancer prevention and treatment to study the role of PAHs and AhR in the development of tumor.

Objective: To study the effects of pharmaco-serum from rabbits administrated intragastrically with Fuzheng Jiedu decoction(FJD) on injured human bronchial epithelial(16HBE) cells exposed to nickel sulfate(NiSO4).Methods: Cultured 16HBE cells were treated with both NiSO4 and different doses of FJD pharmaco-serum in vitro.The detections of cell activities and viabilities were carried out.Meanwhile,activities of glutathione peroxidase(GSH-Px) and superoxide dismutase(SOD) as well as maleic dialdehyde(MDA) contents were measured.Results: FJD pharmaco-serum could decrease mortalities and increase viabilities of 16HBE cells exposed to NiSO4.In cells co-treated with NiSO4 and FJD pharmaco-serum,the content of MDA was decreased,while GSH-Px and SOD activities were increased at the same time.High dose of FJD pharmaco-serum had the most dramatic effect.Conclusion: This study suggested that FJD could antagonize NiSO4-induced toxicity,which may be involved in its antioxidant function.

Objective To analyze factors affecting quality of life (QOL)in patients with chronic hepatitis B (CHB),and provide reference for improving QOL of patients. Methods The MOS 36-item short form health sur-vey (SF-36)was adopted to survey QOL of patients with CHB,Morisky medication adherence scale was used to measure patients'adherence to medication,factors affecting QOL of patients with CHB were analyzed. Results Of 357 CHB patients,271(75.91% )were married,107(29.97% )received college or above education,163(45.66% ) patients'average household monthly income were ￥ 2000-￥ 5000,138(38.66% )patients'family members were also with CHB,198 (55.46% )patients smoked,150 (42.02% )drank. The average score of CHB patients' adherence to medication was (2.15±1.29). Factors affecting QOL in patients with CHB were age,education level, duration of disease,whether or not hospitalized,whether or not drink,as well as adherence to medication. Age, drink,and duration of hepatitis B,and previous hospitalization were negative factors affecting QOL in patients with CHB,education level and adherence to medication were positive factors affecting QOL in patients with CHB. Conclusion Strengthening CHB patients'understanding on disease and improving their medication adherence can help them to improve QOL.

With the quick development of information network,a new disease-Internet Addiction has been paid more and more attention,and how to prevent and cure it has become one important problem that need to be resolved.At present,the rate of Internet Addiction among medical students is rising year by year,so we should make a united effort to prevent and control Internet Addiction among medical students.This article tries to explore how to prevent and control medical students'Internet Addiction from the point of view of law and ethics and expect to prevent them form being patients of Internet Addiction and help them thrive promptly.

As a social problem, Internet Addiction becomes more and more serious,and it has caused wide attention. This paper will state the diagnosis,types,causes,harm,integrated prevention and treatment of Internet Addiction.

Objective To assess the renal protective effects of mycophenolate mofetil(MMF) in diabetic model rats and to explore its mechanism. Methods SD rats were divided randomly into there groups: control group,diabetic model group and diabetic group treated with MMF. In 12 weeks, blood glucose(BG), blood urea nitrogen(BUN), serum creatinine(Scr), index number of kidney hypertrophy(kidey weight to body weight, KW/BW),creatinine clearance(Ccr) and 24- hour urinary protein (24Upro) were detected. Kidney tissure were examined by microscopy. The protein exprssion of intercellular adhesion molecule-1 (ICAM-1) and proliferating cell nuclear antigen(PCNA) in renal tissure were determined by immunohistochemical technique. The mRNA expression of ICAM-1 in kidney tissure were semi-quantitatively determined with reverse transcription-polymerase chain reaction(RT-PCR). Results Compared with control group, BG、KW/BW、24Upro、BUN、Scr and Ccr were significantly increased in diabetic model rats(P

Objective To explore the procedures of 3Q validation for blood coagulation analyzer under the good laboratory prac‐tice(GLP) system based on the Sysmex CA7000 automatic blood coagulation analyzer .Methods Four test indicators of PT ,APTT , TT and FIB were chosen to conduct the performance verification in the within‐run precision ,between‐day precision ,accuracy ,linear‐ity ,carry‐over contamination rate of the automatic blood coagulation analyzer .They were prothrombin time(PT) ,activated partial thromboplastin time(APTT) ,thrombin time(TT) ,and fibrinogen(FIB) .Results The within‐run precision CV values of PT , APTT ,TT and FIB were 1 .33% ,1 .57% ,1 .47% and 1 .90% ,respectively ;the inter‐day precision CV values of PT ,APTT ,TT and FIB were 1 .73% ,1 .52% ,1 .55% and 2 .14% respectively ;in terms of accuracy ,the normal quality control CV values were 7 .45% ,3 .88% ,-4 .98% and 4 .36% respectively ;the abnormal quality control CV values of PT and APTT were 8 .11% and 8 .77% respectively ;the r value of FIB linear correlation coefficient was 0 .999 3 ,the a value was 1 .02 ;the highest CV value of car‐ry‐over contamination rate was 2 .15% ;the detected results all conformed to the general industry standards and requirements of in‐strument manufacturer .Conclusion The 3Q validation under the GLP system proves that the Sysmex CA7000 automatic blood co‐agulation analyzer is good in performance and is appropriate for the laboratory work of clinical laboratory department .

Aryl hydrocarbon receptor (AhR) is a ligand-dependent activation of transcription factor, which is activated by a large variety of ligands, resulting in the expression of metabolic enzymes and a series of downstream gene activation, and closely related with tumor development . Now a review for AhR ligands with different structural and functional and its relationship with tumor, in order to provide a new target for tumor therapy.

Objective To detect plasma amino-terminal pro-brain natriuretic peptide (NT-ProBNP) ,D-Dimer levels in the pa-tients with acute pulmonary embolism (APE) in order to investigate their change characteristics and significance .Methods Among 60 patients with suspected APE ,40 cases diagnosed by CT and meeting the thrombolytic condition were set as the experimental group and other 20 cases of excluded APE by CT as the control group .Plasma NT-ProBNP and D-dimer before treatment in the two groups and after 2-week thrombolytic therapy in the experimental thrombolysis were detected and compared .Results The diagnos-tic sensitivity of NT-ProBNP for early APE was 92 .3% and the specificity was 65% ,while the diagnostic sensitivity of D-dimer for early APE was 100% and the specificity was 70% ;the plasma NT-ProBNP and D-dimer levels before thrombolysis in the experi-mental group were significantly higher than those in the control group with statistical differences (P<0 .01) .Conclusion Plasma NT-ProBNP and D-dimer has important clinical significance for APE and can provide the basis for the early diagnosis and the cura-tive effect observation of the patients with APE .
