Objective To evaluate the vestibular function in patients with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Methods Seventeen CADASIL patients were recruited in the present study and 17 healthy volunteers served as control subjects. Electronystagmogram examinations including gaze nystagmus test, spontaneous nystagmus test, saccade test, pursuit test, optokinetic nystagmus test and caloric test were performed in the subjects. Results Neither patients nor controls had gaze nystagmus or spontaneous nystagmus. There was no difference in the latency and velocity of saccade movement between patients and controls. The accuracy of the saccade movement, the accuracy in leftward saccade, was significantly lower in CADASIL group compared with controls. The pursuit movement gains was also significantly lower in CADASIL group than in control group(G_L:0.79±0.08, G_R:0.76±0.12)(t=-3.739、-2.911,P <0.05) compared with controls(G_L:0.87±0.04, G_R:0.86±0.06).The optokinetic nystagmus gains were significantly decreased in CADASIL group(G_L:0.79±0.17,G_R:0.78±0.18)(t=-2.342、-2.335,P<0.05) compared with controls(G_L:0.90±0.08,G_R:0.89±0.09). The caloric test was performed in one CADASIL patient and the result revealed an incomplete fixing inhibition. CADASIL group was further divided into normal subgroup and abnormal subgroup based on the pursuit curve. The comparison between those two subgroups demonstrated a significant correlation between the pursuit movement and the symptoms of vertigo or dizziness(P<0.05). Conclusions The central vestibular function is impaired in CADASIL patients and the abnormal vestibular function is related to the symptom of vertigo or dizziness in CADASIL patients.

OBJECTIVETo observe the curative effect of integrative medicine for treatment of systematic lupu erythematosus (SLE).
METHODSTotally 110 cases of SLE were randomized into two groups, 50 in the control group and 60 in the treated group, both were treated with prednisone, but to the treated group, integrative medica treatment was given additionally according to syndrome differentiation. The course for both groups was 6 months. Clinical symptoms, immunological indexes, peripheral blood figure, erythrocyte sedimentation rate (ESR), levels of C-reactive protein (CRP) and creatinine (Cr) in blood, and 24 h urinary total protein (u-TP/24 h) were observed before and after treatment.
RESULTSOf the 60 patients in the treated group, the treatment on 29 was evaluated as clinical remission, 18 as remarkably effective, 9 as effective, and 4 as ineffective, the total effective rate being 93.33% (56/60), while that in the control group was clinical remission in 11, remarkably effective in 10, effective in 19, ineffective in 10 respectively, and the total effective rate 80% (40/50), the difference on total ef fective rate between the two groups was significant (chi2 = 4.36, P <0.05). Besides, the improvement in the treated group was superior to that in the control group in terms of clinical symptoms such as fever, arthralgia and baldness (P <0.05, P <0.01); the negative reversion rate of anti-nuclear antibody (ANA, 51.3% vs 28.1%), antidouble-stranded DNA (ds-DNA, 53.6% vs 26.1%), anti- ribonucleoprotein (RNP, 63.2% vs 29.4%) and circulating immnue complexes (CIC, 63.2% vs 29.4%, all P <0.05); lowering of immunoglobulin (for IgG, P < 0.05; IgA, P <0.01; IgM, P <0.01); as well as bettering in peripheral blood figure, ESR, CRP, Cr and u-TP/24 h (P <0.05 or P <0.01).
CONCLUSIONIntegrative medical treatment is obviously effective for SLE patients.

Mesaconitine was incubated with rat liver microsomes in vitro. The metabolites of mesaconitine in rat liver microsomes were identified by ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method with high resolution power. A typical reaction mixture of 100 mol L-1 Tris-HCI buffer (pH 7.4) containing 0.5 gL-1 microsomal protein and 50 micro molL-1 mesaconitine was prepared. The above reaction mixture was divided into six groups, and the volume of each group was 200 micro L. The incubation mixture was pre-incubated at 37 degrees C for 2 min and the reactions were initiated by adding NADPH generating system. After 90 min incubation at 37 degrees C, 200 micro L of acetonitrile was added to each group to stop the reaction. The metabolites of mesaconitine were investigated by UPLC-MS/MS method. Mesaconitine and 6 metabolites M1-M6 were found in the incubation system. The structures were characterized according to the data from MS/MS spectra and literatures. The metabolic reactions of mesaconitine in rat liver microsomes included the demethylation, deacetylation, dehydrogenation and hydroxylation. The major metabolic pathways of mesaconitine in rat liver microsomes were determined by UPLC-MS/MS on multiple reaction monitoring (MRM) mode combined with specific inhibitors of cytochrome P450 (CYP) isoforms, including alpha-naphthoflavone (CYP1A2), quinine (CYP2D), diethyldithiocarbamate (CYP2E1), ketoconazole (CYP3A) and sulfaphenazole (CYP2C), separately. Mesaconitine was mainly metabolized by CYP3A. CYP2C and CYP2D were also more important CYP isoforms for the metabolism reactions of mesaconitine, but CYP1A2 and CYP2E1 haven't any contribution to MA metabolism in rat liver microsomes.

Middle East respiratory syndrome coronavirus (MERS-CoV) has caused outbreaks of SARS-like disease with 35% case-fatality rate, mainly in the Middle East. A more severe outbreak of MERS occurred recently in the Republic of Korea, where 186 people contracted the infections, causing great concern worldwide. So far, there has been no clinically available drug for the treatment of MERS-CoV infection. The potential drugs against MERS-CoV mainly consist of monoclonal antibodies, peptides and small molecular agents. Small molecular agents have an advantage of easier synthesis, lower cost in production and relatively higher stability. There is better chance for those candidates to gain a quick development. This article reviews the progress of developing small molecular MERS-CoV agents.
