OBJECTIVE:To investigate the characteristics of adverse drug reactions (ADR) caused by quinolones in our hospital and to promote their rational use in clinic. METHODS: By a retrospective review,a total of 199 quinolones-induced ADR cases collected from May 2004 to December 2007 in our hospital were analyzed statistically in respect of patients' gender and age,drug species involved,past ADR history,route of administration,clinic manifestations,etc. RESULTS: A total of 9 kinds of quinolones involved in the 199 ADR cases,of which,118 cases were induced by levofloxacin,16.1% had past ADR history,93.5% of the ADR cases were induced via intravenous drip,and most common presentations of the ADR were lesions of skin and its appendants as well as digestive system. There were 7 serious ADR cases. CONCLUSION: The indications of quinolones should be controlled strictly,which should be preferably administered orally and monitoring of its administration should be emphasized in clinical practice to decrease and avoid the occurrence of ADR.

Objective To study the cytotoxic activity of Chinese compound prescription (Xiaozheng Yiliu Decoction) combined with cisplatin on human ovarian cancer OVCAR/DDP cells and its molecular mechanism. Methods The xenograft model was established by injection of OVCAR/DDP cells. Forty nude mice were randomly allocated into four groupsincluding control group, cisplatin treatment group, low-dose Xiaozheng Yiliu plus cisplatin treatment group,and high-dose Xiaozheng Yiliu plus cisplatin treatment group.The apoptosis was determined by TUNEL analysis.The survivin expression was detected by RT-PCR analysis.Results The inhibit rates in cisplatin treatment group, low-dose Xiaozheng Yiliu plus cisplatin treatment group,and high-dose Xiaozheng Yiliu plus cisplatin treatment group,were(5.56±1.14) %,(18.42±7.73) %,and (31.59±12.58) %,respectively,and there were significant differences among the groups(F=8.64,P<0.01 ).The TUNEL analysis showed that the percentages of cell apoptosis were(2.35±1.04) %,(4.56±1.61) %,(12.42±3.68) %,(21.59±5.17) % in four different groups,respectively.After treated by Xiaozheng Yiliu Decoction,the mRNA expression of survivin was found to be down-regulated by RT-PCR analysis. Conclusion Xiaozheng Yiliu Decoction could iucrease the cytotoxic activity of cisplatin on ovarian cancer OVCAR/DDP cells, which may be related to the down-regulation of survivin gene expression.

Objective To establish a TaqMan probe-based real-time fluorescent quantitative PCR ( real-time PCR) for the quantitative and rapid detection of viral reservoir in peripheral blood mononuclear cells (PBMCs) isolated from rhesus monkeys with simian immunodeficiency virus (SIV) infection and to evaluate its preliminary application. Methods A pair of primers and one TaqMan probe were designed ac-cording to the conserved sequence of SIVmac239 strain for real-time PCR amplification. A length of 2 090 bp of nucleotide fragment was digested from the plasmid p239SpSp5 containing 5′-end long segments of SIV-mac239 strain by restriction enzymes EcoRⅠand SpeⅠ. The standards used for quantitative detection of SIV DNA in peripheral blood samples were prepared by a 10-fold serial dilution and used for graphing the stand-ard curve. The numbers of SIV DNA ( copies per 106 PBMCs) in rhesus monkeys during acute and chronic phases of SIVmac239 infection were determined and the virological characteristics of SIV DNA at different phages of infection were analyzed. Results A linear positive correlation between cycle threshold ( Ct) val-ues and concentrations (10 copies/μl to 109 copies/μl) of the standards was found. High levels of SIV DNA were monitored in SIV-infected monkeys 14 to 22 days after acute infection. The levels of SIV DNA in the acute phase of infection were about 1 to 2 logs higher than those in the chronic phase of infection. The num-bers of SIV DNA ( copies per 106 PBMCs) were 1 log lower than the SIV viral load in peripheral blood of the same monkey. The ratios of SIV DNA load to SIV RNA load ( DNA/RNA) in chronic phase of infection were higher than those in the acute phase. Conclusion The established TaqMan probe-based real-time fluorescent quantitative PCR was a highly sensitive and specific assay for the detection of SIV DNA with an advantage of wide linear range. It could be used for the quantitative evaluation of latent reservoirs of SIV.

Objective To study the effect of Shaoyao Gancao Grain on serum prolactin level in female schizophrenia patients with high prolactin induced by risperidone.Methods 100 patients were randomly divided into the control group 50 cases,which were given risperidone. The study group 50 cases,which were given Shaoyao Gancao Grain on the basis of the control group. The two groups were treated for 12 weeks. Positive And Negative Syndrome Scale,serum prolactin and Estrogen level were measured by immunohistochemistry before and after 12 weeks of treatenmt.Results After 12 weeks of treatenmt,serum prolactin levels were decreased in the study group than control group (46.28 ± 14.06 ng/mlvs. 117.89 ± 22.11 ng/ml;t=10.242,P<0.01). PANSS score were decreased in the study group copare with before treatenmt (67.45 ± 7.00vs. 96.53 ± 11.88;t=7.125,P<0.01). PANSS score were decreased in the control group copare with before treatenmt (68.73 ± 7.71vs. 9 7.93 ± 12.65;t=6.541,P<0.01). But there were no difference in PANSS score between the two groups after treatenmt (t=0.682,P>0.05). ConclusionsShaoyao-Gancao grain can decrease serum prolactin level in female schizophrenia patients with high prolactin induced by risperidone,does not affect estrogen levels.

Objective To investigate the relationship between the concentration of plasma (1→3)-?-D-glucan (?-D-glucan) and deep fungal infection. Methods Thirteen patients were recruited in this study, who were suspected with deep fungal infection. G-test TE reagent for ?-D-glucan measurement was used to detect the plasma (1→3) ?-D-glucan in the patients by using UV-2450 spectrophotometer at 545 nm wavelength. The final concentrations were calculated according to concentration conversion formula. Results Nine of thirteen patients were confirmed as deep fungal infection by positive tissue culture, in whom high concentrations of ?-D-glucan were detected, the highest concentration was 352.94 pg/mL (mixed infection), with a mean value of 203.47 pg/mL. In the other four patients with negative culture, the ?-D-glucan concentration was over 54.40 pg/mL in three patients and 16.16 pg/mL in the another. Our results showed that the sensiti-vity, specificity, positive predictive value and negative predictive value of this test were 92.31%, 100%, 100% and 98.36%, respectively. Conclusion G-test TE method is a simple and rapid test and may be used for the diagnosis of patients with deep fungal infection.

Objective To analyze the incidence of the disease, clinical features, diagnostic criteria, therapy and prognosis of Penicilliosis marneffei found in Guangdong province. Methods To analyze patients data, clinical features, laboratory findings, response to therapy, and prognosis of 15 cases Penicilliosis marneffei found in Guangdong province of China. Results The male was predominant compared with the female (ratio 2 to 1) and without occupational preference, but the patients with AIDS as underlying disease were mostly drivers and the unemployed. Thirteen patients were immunocompromised such as AIDS, connective tissue disease, and kidney transplant. Clinical features showed different manifestations, such as high fever, loss of weight, skin lesion, and respiratory system symptoms. Biopsy of the skin lesion showed PAS stain positive yeast-like, or sausage-form spores. Four patients were localized infection of the skin, eleven patients were systemic infection. Nine patients died, five recovered, 1 patient refused to be treated. Fifteen isolates from different anatomic sites of the patients were identified to be Penicillium marneffei by morphology and dimorphism in the culture, and eleven isolates among these 15 isolates were also confirmed by DNA sequence analysis. Conclusion The incidence rate of Penicilliosis marneffei become higher in the recent years and many patients were accompanied with AIDS in Guangdong province. Attention should be paid to the disease.
