Objective To study the blood concentration of hydroxychloroquine in patients with systemic lupus erythematosus (SLE) treated with different doses, and analyze the relationship between blood concentration of hydroxychloroquine and disease activity, and evaluate its safety.Methods Forty SLE patients were randomly divided into 2 groups, each group contained 20 cases.The patients in group A were treated with hydroxychloroquine (0.4 g, qd), while patients in group B were treated with hydroxychloroquine (0.2 g, qd).The treatment lasted more than six months in every patient.The blood concentrations of hydroxychloro-quine were detected by high performance liquid chromatography.The clinical and laboratory indices were collected.The systemic lupus erythematosus disease activity index (SLEDAI) score was recorded.The doses and varieties of combined hormone, immunosuppressant were recorded.The correlation of blood concentration of hydroxychloroquine and disease activity was analyzed.The significance was determined by Student's t test and Pearson correlation analysis.Results In SLE patients, the average blood concentration of hydro-xychloroquine was (402±190) ng/ml in group A and (150±60) ng/ml in group B (t=7.471, P＜0.01).The disease activities of patients in the two groups showed no significant difference (t=-0.172, P＞0.05).The platelet counts of patients in group A were significantly higher than those in group B[(188±88)×109/L vs (158 ±87) ×109/L] (t=4.375, P＜0.05).However, the other laboratory parameters showed no significant difference between the two groups (P＞0.05).Conclusion The results of this study indicate that the blood concentrations of hydroxy-chloroquine are significantly different in different dosages.The high dose of hydroxy-chloroquine is related to high platelet number in lupus patients.These findings suggest that hydroxychloroquine is safe and effective for SLE patients.

Objective:To find the reasons for the low dissolution of clarithromycin tablets and study the interference from filter film adsorption at various time points to explore the appropriate processing approach for dissolution solution of clarithromycin tablets. Meth-ods:Clarithromycin tablets from two different manufacturers were used. The dissolution solution was prepared according to Japanese Orange Book. The dissolution was determined after different processing and the adsorption rate of the filter film was calculated. Re-sults:Totally 14 kinds of filter films were tested with different adsorption for clarithromycin, and the adsorption rate of some kinds of filter films exceeded the prescribed limit. Conclusion:The absorption rate of filter films for clarithromycin can be decreased by boiling the films and using American membranes. The interference from filter film adsorption can be reduced and inhibited by rejecting the first filtrate above 5ml or centrifuging dissolution solution.

Objective To investigate clinical characteristics,diagnosis,treatment and prognosis of mucormycosis in patients with renal failure. Methods We reported a 65-year old case of mucormycosis with chronic renal failure. The patient was successfully treated with amphotericin B. Mucormycosis complicated with renal failure were reviewed excluding mucormycosis peritonitis associated with peritoneal dialysis and desferrioxamine-related mucormycosis. Results Fifteen cases including our case were involved with mean age of 49.87?15.84 years old. Rhinocerebral,pulmonary,and disseminated forms accounted for 46.7%,33.3% and 20% respectively. Autopsy was made in 46.7% of patients. Mortality was 73.3% in all of them and 42.9% in seven patients who received antifungal therapy. All patients without treatments died. Conclusion Mucormycosis is a lethal invasive infection in patients with renal failure. The management to improve prognosis are early diagnosis,surgical debridement,drainage and aggressive antifungal chemo-therapy.

The present study aims to predict the action targets of antidepressant active ingredients of Xiaoyaosan to understand the "multi-components, multi-targets and multi-pathways" mechanism. Using network pharmacology, the reported antidepressant active ingredients in Xiaoyaosan (saikosaponin A, saikosaponin C, saikosaponin D, ferulic acid, Z-ligustilide, atractylenolide I, atractylenolide II, atractylenolide III, paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid and pachymic acid), were used to predict the targets of main active ingredients of Xiaoyaosan according to reversed pharmacophore matching method. The prediction was made via screening of the antidepressive drug targets approved by FDA in the DrugBank database and annotating the information of targets with the aid of MAS 3.0 biological molecular function software. The Cytoscape software was used to construct the Xiaoyaosan ingredients-targets-pathways network. The network analysis indicates that the active ingredients in Xiaoyaosan involve 25 targets in the energy metabolism-immune-signal transmutation relevant biological processes. The antidepressant effect of Xiaoyaosan reflects the features of traditional Chinese medicine in multi-components, multi-targets and multi-pathways. This research provides a scientific basis for elucidation of the antidepressant pharmacological mechanism of Xiaoyaosan.

Bactericidal/permeability-increasing protein (BPI) can bind to and specifically neutralize lipopolysaccharide (LPS) from the outer membrane of Gram-negative bacteria. In order to evaluate potent LPS-neutralizing activity of bovine BPI, the full-length coding sequence (1 449bp) or 714 bp N-terminal coding sequence (BPI714) of bovine BPI was transfected into mHEK293 cells and the expression of LPS-induced inflammatory cytokines was studied. First, we constructed the lentiviral expression vectors and generated mHEK293 cells stably expressing recombinant bovine BPI or BPI714. Then, we detected the expression of IL-8, IL-1β, TNF-α, NF-κB-1 and NF-κB-2 genes by real-time PCR at 0, 1, 3, 6, 12, 24, 36 and 48 h post of LPS induction in cells with or without recombinant bovine BPI or BPI714 ectopic expression, respectively. In response to LPS, the robust abundance of inflammatory cytokines including IL-8, IL-1β, TNF-α and NF-κB-2 was observed in wild type mHEK293 cells at eachtime point. On the contrary, mRNA abundance of IL-8, TNF-α and NF-κB-2 in transfected mHEK293 cells showed no significant changes at each indicated time point. Our results demonstrated that recombinant bovine full length BPI or BPI714 down-regulated the expression of inflammatory cytokines and revealed that either of bovine BPI or BPI714 was able to inhibit the immune respond stimulated by LPS. This study provides evidence for further investigating the mechanisms and application of BPI/LPS-neutralizing activity and also documents a reliable approach for analysis of the efficacy of antibacterial proteins.
