Mesalamine (5-aminosalicylic acid, 5-ASA) is used for ulcerative colitis, mild Crohn′s disease. The orally taken mesalamine is excreted primarily as N-acetyl-5-aminosalicylic acid (N-acetyl-5-ASA) via urine, renal damage and hematuria are rare. However, red-brown urine discoloration has been noted by some patients, which is associated with the reaction between N-acetyl-5-ASA and remaining hypochlorite in the disinfectant-containing water. This article reports a case of mesalamine-associated red-brown urine discoloration and reviews related literatures.

Objective To explore the effect of appreciation intervention on anxiety and complications in patients with renal biopsy. Methods A total of 197 cases of renal biopsy patients were divided into the control group (n=96) and the observation group (n=101). The observation group was given comprehensive nursing intervention with appreciation, the control group was only given comprehensive nursing care, the two groups were evaluated with Zung Self-rating Anxiety Scale (SAS) upon admission and 1 week after puncture. Results After intervention, the SAS score of the observation group was 30.87 ± 4.52, and the SAS score of the control group was 32.32 ± 3.72, and the difference between the two groups was statistically significant (t=2.45,P<0.05). Totally 97 patients in the observation group and 78 cases in the control group received bed urination exercises, and the difference between the two groups was statistically significant (χ2=9.412,P<0.01). The complications of two groups were collected, the complications in the observation group were 27 cases, and the complications in the control group were 50 cases, the difference between the two groups was statistically significant (χ2=13.285,P<0.01). Among the postoperative complications, 8 of the patients in the observation group had urinary retention, and 19 of the control group had urinary retention (t=2.446,P=0.015). In the observation group, 3 cases had abdominal distention, and 10 cases in the control group suffered from abdominal distension (t=2.117, P=0.035). In the observation group, 1 case had low back pain, and 6 cases in the control group suffered from lumbago (t=2.004, P=0.047); the difference was statistically significant. Conclusions Appreciate intervention for patients with renal puncture biopsy has a positive impact on the bed urination exercise in puncture before surgery. It can alleviate the anxiety of patients received renal biopsy, reduce urinary retention, abdominal distension and pain complications, and improve bedridden experience.

Objective:To know the work status of clinical pharmacy in medical institutions of Guizhou province. Methods:Ques-tionnaires were used to analyze the situation of clinical pharmacy in 108 medical institutions of Guizhou province. Results: A total of 246 questionnaires were taken back, and among the 231 valid questionnaires were received including gradeⅡor above hospitals. The main contents of clinical pharmacy work carried out in medical institutions included 7 aspects: pharmacists ’ participation in ward rounds, which accounted for 47. 11%; pharmacists’ participation in case consultation, which accounted for 16. 65%; pharmacists’ participation in teaching practice, which accounted for 38. 84%; pharmacists’ participation in prescription evaluation and analysis, which accounted for 72. 73%;pharmacists’ participation in antimicrobial drug monitoring and drug use evaluation, which accounted for 62. 37%;pharmacists’ participation in drug counsultation and education, which accounted for 58. 68%;pharmacists’ participation in adverse drug reaction monitoring and supervision, which accounted for 77. 32%. Conclusion:The development of clinical pharmacy in Guizhou province still lags behind, and the number of clinical pharmacists is insufficient, which can’ t meet the growing demand for personalized medicine. In particular, the development of clinical pharmacy is restricted by the limited pharmaceutical service. The cog-nition degree of pharmacist group in Guizhou province has been improved. However, the number and the service quality of clinical pharmacists need to be improved further.

Objective To evaluate the influence of highly active antiretroviral therapy ( HAART) on bone mineral density ( BMD ) of human immunodeficiency virus ( HIV) infected patients and correlating clinical factors. Methods The clinical data from 2007 to 2008 were analyzed, including 50 patients treated with HAART (named treated group) ,12 HIV-infected antiretroviral-naive patients (named untreated group) and 20 healthy people (named control group).Lumbar, femoral neck, femur, femoral greater trochanter and whole body BMD were measured by dual energy X-ray absorptiometry.The data were respectively analyzed.Results There were 19 (38.0% ) patients with osteopenia and 1(2.0% ) patient with osteoporosis in the treated group.There were 6(50.0% ) patients with osteopenia and 2 (16.7% ) patient with osteoporosis in the untreated group.There were 5(25.0% ) patients with osteopenia, no one with osteoporosis in the control group.The prevalence of osteopenia/osteoporosis was statistically higher in the untreated group than that in the control group (P = 0.02).The BMD of femur, femoral neck and greater trochanter [(0.97±0.14) , (0.91 ±0.13 ) , (0.76 ±0.12) g/cm2] in the HIV-infected group (including the treated and untreated group) were significantly lower than that in the control group [(1.04±.12) , (0.98±.14) , (0.84±0.11) g/cm2 ,P <0.05].There were no significantly differences in the BMD between the untreated group and the treated group.In the treated group, osteopenia/osteoporosis correlated with body weight less than 60 kg (r=0.074,P =0.004) and the viral load before HAART(r=5.103,P =0.021).Conclusions The prevalence of osteopenia and osteoporosis in antiretroviral-naive HIV-infected patients is higher.The BMD of HIV-infected patients are reduced compared with the healthy people.The BMD is similar among HIVinfected patients irrespective of antiretroviral treatment Body weight less than 60 kg and the viral load before HAART are the risk factors of osteopenia/osteoporosis for the HIV-infected antiretroviral patients.

Objective To study the profile of peripheral natural killer cells(NK cells)and γδT lymphocytes in human immunodeficiency virus(HIV)infected patients with different disease status and to explore the pathogenesis of acquired immunodeficiency syndrome(AIDS).Methods Three hundred and eleven HIV/AIDS patients without antiviral treatment were enrolled in this study.The percentages and absolute numbers of CD4+T lymphocytes,NK cells,and γδT ceils were measured by flow cytometry.The patients were divided into 3 groups based to their CD4+T lymphocytes counts:low CD4+T lymphocytes group(L),patients with CD4+T lymphocytes <0.20×109L;middle CD4+T lymphocytes group(M),CD4+T lymphocytes counts between 0.20×109and 0.35×109L;high CD4+T lymphocytes group(H),patients with CD4+T lymphocytes counts >0.35×109L.Rank sum test of independent samples of two-group and multiple-group was performed using Mann-Whitney U test and Kruskal-Wallis test.Correlation analysis was done by Spearman and Pearson test. Results The median percentage and cell counts of NK cells(8.4%,103×106L) and γδT cells(3.4%,41×106L)in HIV/AIDS patients were all significantly lower than those of healthy individuals(Z=-5.029,Z=-7.723,Z=-2.437,Z=-6.063;all P<0.01).The median cell counts of CD4+T lymphocytes in L,M,H groups were 0.062×109L,0.276×109L and 0.482×109L,respectively.The median cell counts of NK cells in these 3 groups were 89×106L,97×106L and 146×106L,respectively.NK cell counts were not significantly different between L and M groups,whereas both of them were much lower than that of H group(Z=-3.392,P=-0.001,Z=-4.849,P<0.01,respectively).The median γδT cell counts of L,M and H group were 29×106L,43×106L and 59×106L,respectively.The differences between any 2 groups were not significant.Conclusion These data suggest that the decreasing levels of peripheral NK cells and γδT cells are different after HIV infection.

Objective To investigate the clinical features, therapeutic approaches, outcomes and alterations of peripheral lymphecytos subsets in cytomegalovirus (CMV) infections in patients with AIDS.Methods Ninety-six cases of AIDS were treated in Peking Union Medical College Hospital and 23 of them had CMV infection. We analyzed the clinical features, peripheral lymphocytes subsets, outcomes, CMV pp65 antigen and/or specific anti-CMV lgM. Results In the 23 CMV patients, nonspacific symptoms including fever,cough,chest distress and diarrhea occurred in 18, 11,9 and 8 patients, respectively. Thirteen patients had retinitis identified by ophthalmofundoscepy, 7 of them had blurred vision or floating as primary symptoms. Pneumocystis pneumonia, tuberculosis infection and other infection appeared in 18 patients.Fifteen(65. 2% )of the patients had positive serum tests. The positive rates for CMV pp65 and specific anti-CMV-IgM were 43.5% and 30. 4%, respectively. CD4+T cell count in CMV patients was remarkably decreased than that in non-CMV patients [14 (4,39) cells/μl vs (48 ( 12,128 ) cells/p J, P = 0. 005] and the proportion of CD8+ CD38+ T cells in CMV patients was higher than that in non-CMV patients,whereas the difference of CD8+T cell was not statistically different between the 2 groups. Conclusions CMV infection often occurrs in advanced AIDS patients. In HIV/AIDS patients with CD4+ T cell count ≤ 100 cells/μl,routine check for CMV pp65 antigen, specific anti-CMV IgM and ophthalmofundoscopy are recommended.Whenever encountering a young patient presenting with fever, blurred vision or floating, CMV complicating AIDS should be considered.
