AIDS has become a global disease,and a variety of drugs are used in the treatment of AIDS ,but the interindividual variabilities in efficacy and toxicity remain important limitations for the use of these drugs.Studies have shown genetic polymor-phism is the main reason for interindividual variabilities of drug reaction.In recent years,scholars focused on the pharmacog-enomics of anti-AIDS drugs and found that genetic polymor-phisms,in large part,determine the interindividual variabilities of the responese of these drugs.This paper reviews the research progress on pharmacogenomics of the four types of anti-AIDS drugs commonly used in China,including nucleoside reverse transcriptase inhibitors (NRTIs),non-nucleoside reverse tran-scriptase inhibitors (NNRTIs),protease inhibitors (PIs)and integrase inhibitors (raltegravir).

Objective To investigate the peripheral blood Th17 and CD4 + CD25 + regulatory T cell levels and their correlations in patients with primary hepatocellular carcinoma (PHC).Methods Peripheral blood samples were collected from 30 PHC patients and 25 healthy controls in the First Affiliated Hospital of Zhejiang University from June 2008 to May 2009.Mononuclear cells were isolated and the Th17 and CD4 + CD25 + regulatory T cells were detected by flow cytometry and compared between patients and controls by t test.Spearman test was performed to analyze the correlation of Th17 with CD4 + CD25 +regulatory T cell concentrations.Results The levels of Th17 and CD4 + CD25 + regulatory T cells in peripheral blood in healthy controls were (2.10 ± 0.87) ％ and (7.10 ± 2.32) ％ ; while those in PHC patients were (3.38±1.68)％ and (11.78±5.62)％ (t=3.640 and 4.162,P＜0.01).The level of Th17 cells was positively associated with that of CD4 + CD25 + regulatory T cells in PHC patients (r =0.821,P ＜0.01).Conclusion The levels of Th17 and CD4 + CD25 + regulatory T cells in peripheral blood are high in PHC patients and positively correlated with each other,which indicates that CD4 + CD25 + regulatory T cells may contribute to the disease progression and pathogenesis of carcinoma through inducing Th17 cells differentiation.

Since 1970's , lots of studies on biodegradation of chloroanilines (CAS) have been done, especially, in these aspects: spieces and capability of the microbes; metabolic pathway; gene cloning, expression of degradation plas-mid and pivotal metabolic emzymes. It is necessary for us to review the study on biodegradation of chloroanilines in order to summarize some useful results and the problems in this study.

Objective To study the clinical results of early surgery for acute cervical spinal cord injury. Methods 24 cases of acute cervical spinal cord injury were treated with early surgery in our hospital from 1999 to 2002. The average interval from injury to surgery was 67 hours. The injured cervical segments were reduced, decompressed and fixed through anterior approach, posterior approach or anterior posterior approach. Results 22 cases got follow ups of 12 to 38 months (mean 18 months), but 2 cases were lost. 2 cases of the 11 patients of ASIA Grade A did not experience any restoration, but all the other patients got significant restoration and an average improvement of 1.8 ASIA grades. Conclusion Operation should be performed as soon as possible for acute cervical spinal cord injury, for good results can be achieved by early surgery.

A total of 61 Strains were isolated from five perennial ryegrass(Lolium perenne L.)varieties——SR4000, CalypsoⅡ, Pinnacle, Topgun and Justus. By subculture, the stable strains were separated into four morphological groups(MGs). Based on the morphological characteristics and the results of AP-PCR, 57 strains of them were identified as Neotyphodium lolii.

10?) and delayed union of tibia in 4 sides. Conclusion Many factors can affect the prognosis of tibial Pilon fracture, but the key points for a successful operation are right procedure and timing of surgery.

Objective To determine the difference of macrophage RAW264.7 apoptosis induced by Brucella melitensis virulent strain 16M and attenuated strain M5-90 and elucidate the regulatory role of caspases 3,8 and 9.Methods The best multiplicity of infection (MOI) was determined through kinetic analysis of Brucella melitensis strain 16M and M5-90 induced mouse macrophages apoptosis(bacterium ∶ cell =100 ∶ 1,50 ∶ 1,10 ∶1).The infection model was established using the best MOI =50 ∶ 1.The numbers of in vivo bacteria by colony formation units were calculated after macrophages were infected for different times,including 2,4,8,12,24 and 48 h,and the infected cells were collected.The ratios of apoptosis were detected and the regulation of caspases 3,8 and 9 in apoptosis pathway was elucidated by flow cytometry.Results The numbers of 16M in vivo bacteria were 105.4,104.8,105.8,106.5,108.0 and 109.0,respectively and of M5-90 were 106.1,106.2,106.4,106.3,106.1 and 105.0,respectively.The number of in vivo bacteria of 16M was significantly increased than that of M5-90 after infected for 24 h to 48 h.The ratios of apoptosis induced by 16M after infected for 2,4,8,12,24 and 48 h was (2.67 ± 0.09)％,(13.13 ± 0.30)％,(6.56 ± 0.42)％,(6.49 ± 0.28)％,(16.07 ± 0.86)％ and (24.23 ± 1.67)％,respectively,and by M5-90 was (3.62 ± 0.02)％,(32.01 ± 2.59)％,(17.58 ± 0.44)％,(16.09 ± 0.10)％,(62.53 ± 2.70)％ and (85.53 ± 0.15)％,respectively,and by control group was [(1.90 ± 0.20)％,(1.92 ±0.16)％,(1.99 ± 0.03)％,(2.48 ± 0.11)％,(3.56 ± 0.07)％,(5.26 ± 0.33)％].The differences were statistically between groups in same time.The Brucella melitensis vaccine strain M5-90 was more powerful than virulent strain 16M in respect of inducing macrophage apoptosis after infected for 24 to 48 h.Twenty-four hours after infection,the expression of caspases 3,8 and 9 was (1.47 ± 0.05)％,(1.52 ± 0.02)％ and (2.47 ± 0.12)％,respectively,in control group and the expression was (9.70 ± 0.46)％,(6.08 ± 0.56)％ and (35.08 ± 1.64)％,respectively,after infected for 24 h induced by M5-90.The expression of caspases 3,8 and 9 was significantly higher than that control group (P ＜ 0.01).Twenty-four hours after given caspases 3,8 and 9 inhibitor,apoptosis rate in control group was (66.72 ± 1.28)％,in M5-90 group was (22.58 ± 0.55)％,(53.15 ± 1.85)％ and (29.18 ± 0.23)％,respectively,and compared with control group,apoptosis rate of caspases 3,8 and 9 was significantly lower(P ＜ 0.01).Conclusions Apoptosis of macrophage can be induced by Brucella melitensis virulent vaccine strain 16M and attenuated strain M5-90.M5-90 is stronger than that of strain 16M.Caspases 3,8 and 9 can regulate macrophage apoptosis after M5-90 infection.
