Objective To determine the incidence, clinical manifestation and risk factors of immune reconstitution inflammatory syndromes (IRIS) in highly active antirctroviral therapy (HAART) for HIV/AIDS patients. Methods Two hundred and twelve HIV/AIDS patients received HAART, and were followed up for 6 months. The incidence time and disease spectrum of IRIS were observed. Multiple logistic regression analysis was performed to identify the risk factors for IRIS. Results Among 212 patients, there were 59 (27.8%) experienced an IRIS event during the first 6 months of HAART, 2 of which died (2/59,3.39% ). Median time of IRIS onset was 21 days form HAART initiation. The disease spectrum included tuberculosis, herpes virus infections, pneumocystis jirovecii pneumonia, cryptococcal meningitis and penicillium marneffei infection. Risk factors of IRIS included baseline infections ( OR = 1. 655, P =0.010),fever during HAART ( OR = 2. 344, P= 0.006), and baseline CD4 + count ( OR = 1. 556, P = 0. 034).Conclusions IRIS usually occurred within the first month from HAART initiation, and tuberculosis and herpes virus infection are most common. The occurrence of IRIS is associated with the antigens burden and the decreased baseline CD4 + count.

OBJECTIVETo investigate effects of zearalenone (ZEA) on the proliferation of SK-N-SH human neuroblastoma cells in vitro and its possible mechanism.

METHODSSK-N-SH cells were cultured in estrogen-free improved minimum essential medium and divided into 5 groups based on different treatments: group 1, without treatment; group 2, treated with 17beta-estradiol (E(2)); group 3, treated with ZEA; group 4, treated with both E(2) and ICI 182780; group 5, treated with both ZEA and ICI 182780. Absorbance value (AV) was determined at the time point of 0, 24, 48 and 72 hours, and DNA proliferation index (PI) at 72 hours. Flow cytometer, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) were employed to monitor cell apoptosis.

RESULTSAt 24, 48 and 72 hours, the AV of group 3 were 1.39, 1.32, and 1.22 times to those of group 1, respectively. PI in group 3 was 1.43 times of that in group 1 at 72 hours. The results of group 2 were similar to those in group 3. At the same time, the growth of cells was inhibited by ICI 182780 despite the presence of E(2) and ZEA. Apoptosis cells were abundant in group 1 and ICI 182780 groups, but little in E(2) and ZEA groups.

CONCLUSIONZEA might promote the proliferation of SK-N-SH cells to a level similar to that of E(2), which might probably be brought about via estrogen receptor pathways and depressing apoptosis.

Objective: To investigate the influence of esculentoside A（EsA） on production of IL-1 and TNF by rabbit synovial cells induced by LPS. Methods: levels of IL-1 and TNF in the supernatant of rabbit synovial cell were determined by examining proliferation of thymic cells and by bioassay L929 cells as target cells, respectively. Results: EsA in 5-40 μg/ml could significantly inhibit the production of IL-1 and TNF from rabbit synovial cells induced by LPS. Conclusion: EsA can inhibit the production of IL-1 and TNF from synovial cells. It suggests that EsA may play a role in improving the rheumatoid arthritis.

Objective To investigate the efficacy and safety of vasopressin receptor antagonist tolvaptan for treating dilutional hyponatremia casused by decompensated liver cirrhosis.Methods Ninety-six subjects with decompensated liver cirrhosis complicated by dilutional hyponatremia were divided into test group (n =56) and control group (n =40) by double blind method.Test group were treated with a single dose of tolvaptan 15 mg orally in addition to routine therapy,while control group were treated with routine therapy plus placebo.The changes in serum sodium concentration,liver functions,ascites,and edema of lower extremities between the two groups were observed.Measurement data were compared by t test,and categorical data were compared by chisquare test.Results On day 7,36 (64.3％) patients in test group and 9 (22.5％) patients in control group reached normal serum sodium concentrations (x2 =5.241,P＜0.01).All the patients in test group and only 3 patients in control group had 24 hours' total urine volume above 3500 mL.Difference of 24 hours' total urine volume during 7-day treatment between the two groups was statistically significant (t=20.899,P＜0.01).Thirty-nine patients in test group and 15 patients in control group had reduced ascites (x2 =4.260,P=0.039),but improvement of edema in lower extremities of both groups was comparable (12 cases in test group and 7 cases in control group; x2 =0.227,P=0.634).Serum alanine aminotransferase (ALT),total bilirubin (TBil),potassium and creatinine levels of test group were improved after treatment,but were not significantly different from either baseline levels (t=1.509,0.783,1.107,1.237; both P＞0.05) or those of the control group (t=1.712,1.635,1.121,0.873; both P＞0.05).Conclusions Single dose of tolvaptan (15 mg) exerts a strong diuretic effect and is able to greatly increase serum sodium concentration,thus has distinct therapeutic effect for patients with decompensated liver cirrhosis complicated by dilutional hyponatremia.

Objective To determine the incidence, clinical manifestation and part of lymphokines which represent the balance of Th1 and Th2 in the role of the immunologic mechanisms for IRIS(immune restoration inflammatory syndromes)in patients initiating HAART(Highly Active Antiretroviral Therapy).Methods A prospective study of all patients initiating HAART was performed. A period of six months tracking initiating HAART was performed. The incidence of IRIS, time of occurrence and clinical disease spectrum were recorded. The main T lymphokines including IL-2, INF-γ, IL-4, IL-10 which on behalf of the balance of Th1 and Th2 were detected. To explore the immunopathologic mechanisms for IRIS, the levels of T lymphokines at pre-HAART, initiating HAART for 1 month, 3months and 6 months were compared in IRIS group and non-IRIS group, healthy group. Results A total of 212 patients were enrolled in this study. 59 patients were diagnosed as IRIS at a median of 21 days after HAART initiation (QR 19 days).The main disease spectrum included tuberculosis, herpes virus infections, pneumocystis jirovecii pneumonia. No matter in the IRIS group or non-IRIS group, the main lymphokines baseline of IL-2, INF-γ reduced and IL-4, IL-10 increased before HAART compared to healthy group (P ＜ 0. 05), which had the tendency to restore balance relations initiating HAART. The lymphokines levels had significant difference between baseline and 6 months initiating HAART (P ＜ 0. 05). The changed levels of lymphokines between IRIS group and non-IRIS group before HAART had significant difference compared to healthy group. IL-2, INF-γ increased level[(11.68 ± 2. 89) pg/ml vs (8.52 ±2.26) pg/ml; (22. 19 ± 6. 22) pg/ml vs (18.34 ±5. 35) pg/ml] and IL-10 decreased level [(19. 21 ± 4. 03) pg/ml vs (23. 19 ± 5.92) pg/ml] had significant difference between IRIS group and non-IRIS group initiating HAART I month(P ＜0. 05). Conclusions The incidence of IRIS during 6 months initiating HAART in HIV/AIDS was 27. 8%, IRIS usually occurred in 1 month initiating HAART. The most common disease spectrum was infectious disease, including tuberculosis and herpes virus infection. Lymphokine of Th1 and Th2 existed unbalance in IRIS group and non-IRIS group before HAART. The unbalance tendency in IRIS group was more obvious. All lymphokines had the trend to recover balance. IL-2, INF-γ significantly increased and IL-10 significantly decreased, which might involve the occurrence of the IRIS.
