Objective To investigate the safety,therapy and prophylactic effect of Omeprazole on stress ulcer in children with epidemic type B encephalitis.Methods Before and after medication,chest X-ray examination was performed.The result of occult blood(OB) was confirm by Colloidal gold assay in stool and/or gastric juice.Based on the result of OB,the patients were divided into therapy group[besides conventional therapy for encephalitis,Cimitidine group and Omeprazole group with positive result OB,was administered with 0.9% normal sodium 100 mL+Cimitidine 20-40 mg/(kg?d),iv,q12 h and normal sodium 100 mL+Omeprazol 0.5-0.8 mg/(kg?d),iv,qd,respectively] and prophylaxis group(Cimitidine group,Omeprazole group and control group,with negative result OB,were administered with same medicines as therapy group,respectively.Except control group being administered only 0.9%NS 100 mL,iv,(q12 h)).The effects of drugs on hemostasis,preventing hemorrhage,and the potential risk of acquired pneumonia result from drugs used were observed.Results In therapy group,the average time of hemostasis in Omeprazole group was obviously shorter than that of in Cimitidine group,there was significant difference between two groups(P0.05).Conclusions Both of the drugs is safety and effect to therapy or prophylaxis for the latent stress ulcer in short term.The effect of Omeprazole is better than those of Cimitidine.Using Cimitidine and Omeprazole,neither therapy nor prophylaxis for stress ulcer increaseds the potential risk of acquired pneumonia in children with epidemic type B encephalitis in this study.

Gadd45a, a p53 and BRCA1-regulated growth arrest and DNA damage gene, plays important roles in suppressing cell transformation and tumor malignancy. Gadd45a maintains the genomic stability through inhibiting the cell growth and promoting the DNA repair etc, by which it suppresses the tumor development. Additionally, Gadd45a is involved in some important signaling pathway, contributing to its function in tumor suppressing.

Objetive To study the effect of Paeonol on PGI,TXA2,ET and NO in diabetic rats.Methods Streptozocin was used in dosage of 60 mg/kg on rats to make diabetic animal model.Defferent dosages of Paeonol were used on diabetic animal models.6-Keto-PGF1?,TXB2,ET and NO were tested after 30 days. Results Compared to the control group,6-Keto-PGF1?(pg/mL)of Paeonol groups increased from 89.75? 2.75,89.97?7.28,89.97?11.36 to 120.03?13.85,108.34?11.25,105.32?8.85 respectively;TXB2 (pg/mL)decreased from 157.64?10.36,156.64?11.35,153.33?19.40 to 124.46?18.67,136.40?18.15, 138.40?22.20 respectively;ET(pg/mL)decreased from 181.68?5.10,181.27?4.76,181.04?4.19 to 140.55?3.01,150.51?2.22,161.02?3.76.The change of 6-Keto-PGF1?,TXB2 and ET was related to the dosage of Paeonol.NO has no significant change.Conclusions Paeonol can decrease the ET and TXB2 in diabetic rats,and increase 6-Keto-PGF1?in diabetic rats.

[Objective]To detect the effect of constant magnetic field on metal ion Co2+,Cr3+ induced TNF-? secreted by human mononuclear cells,and to search a method for prevention and treatment of aseptic loosening. [Methods]CoCl2 powder and CrCl3 powder were dissolved in the asepsis injecting water. Mononuclear cells from human peripheral blood,were taken and cultured with Co2+,Cr3+ ions in different magnetic field of 10Gs,100 Gs,1000Gs for 12,24 and 48 hs. There were nine groups:control group,Co2+ group,Cr3+ group,Co2+andCr3+ with various intensities of constant magnetic field,respectively.ELISA method was applied to detect tumor necrosis factor (TNF-?) in serum via the absorbance (A).[Results]Co2+ and Cr3+ ions stimulated human mononuclear cell to secrete TNF-?

Indoleamine 2,3-dioxygenase 1 (IDO1) and tryptophan 2,3-dioxygenase (TDO) catalyze the initial and rate limiting step in the catabolism of tryptophan, which is related to tumor immune tolerance and poor prognosis in patients. In this regard, two enzymes have become important therapeutic targets for tumor immunotherapy. So far, nine IDO1 inhibitors and three IDO1/TDO dual inhibitors have entered clinical trials. This review summarizes the research progress of IDO1 inhibitors, TDO inhibitors and IDO1/TDO dual inhibitors from the perspective of medicinal chemistry.

Medical English is an indispensible tool subject for medical students.However,the limited in-class teaching hours fail to provide adequate opportunities for students to participate in a diversity of subject-based tasks to practice medical English.Therefore,extracurricular activities serve as a complement to in-class teaching.Moreover,the features of extracurricular activities conform to those of Content-based instruction ( CBI),a teaching mode adopted in the teaching of ESP ( English for special purposes).The specific forms of extracurricular activities can be designed based on need analysis to cultivate the students' language competence in communicating biomedicine in Medical English.

The language of English medical papers should be accurate, precise, clear and objective. Unfamiliar with these features and influenced by mother tongue, Chinese authors are prone to use unnecessary words, subjective expressions and long and confusing sentences, etc. To avoid those mistakes, they are suggested to practice a lot, keep a good reading habit and equip themselves with necessary searching skills, etc.

The latest results from our research group in the biotransformation of triptolides and bufadienolides were reviewed. The trends in the development of biotransformation in the future were also briefly discussed.

Objective To investigate the effect of blood-flow-activating and blood-stasis-removing herbal medicine on the vision of primary glaucoma patients.Methods A retrospective study was carried out in 60 eyes of primary glaucoma from 32 cases.The cases were allocated to Group A and Group B.Group A(n=33 eyes)was treated with routine drugs of lowering intraocular pressure and operation and Group B(n=27 eyes)with blood-flow-activating and blood-stasis-removing herbal medicine additionally.Results After treatment,the vision of 8 eyes( 24.24%)in Group A and 16 eyes ( 59.26%)in Group B was improved,and the difference was significant(P 0.05).Conclusion Blood-flow-activating and blood-stasis-removing herbal medicine combined with routine treatment is helpful for the increase of vision of primary glaucoma.
