The transmission electron microscopy revealed cryoglobulinemia associated renal damage .This report shows that the clinicopathological characteristics in patients with Rhupus syndrome associated nephropathy are complicated .The renal pathology can be used as a diagnostic tool .

Objective To investigate the effects of two different dosages of dexmedetomidine on short-latency somatosensory evoked potentials (SLSEP)in intracranial surgery.Methods Forty pa-tients,ASA Ⅰor Ⅱ,aged 20-65 years old,selected for intracranial surgery were randomly divided in-to two groups,20 patients in each group.Bolus dose of 0.5 μg/kg dexmedetomidine was infused within first 10 min and followed by continuous infusion of 0.5 μg·kg-1·h-1 for 10 min in group A;Bolus dose of 1.0 μg/kg dexmedetomidine was infused within first 10 mins and followed by continu-ous infusion of 1.0 μg·kg-1·h-1 for 10 min in group B.SLSEP indications include N20-P25 amplitute and N20 latent period were observed.MAP,HR,N20-P25 amplitute and N20 latent period were re-corded respectively before dexmedetomidine adminstraition (T0 )and 20 mins after dexmedetomidine adminstraition (T1 ).Results Compared with T0 ,MAP and HR at T1 significantly decreased in both groups(P <0.05).N20-P25 amplitude had no statistically significant difference in both groups,while N20 latent period significantly prolonged (P <0.05).Conclusion Both doses of 0.5 μg/kg and 1.0μg/kg dexmedetomidine can significantly prolong the latent period of N20.

This study is to investigate the sedative and hypnotic effects of a novel compound H1208. The sedative activity of H1208 was investigated by recording the spontaneous locomotor activity of mice. The hypnotic property was evaluated by the latency and duration of sleep (loss of righting reflex) in mice and the effect of hypnotics on sleep pattern of electroencephalogram were studied in conscious, freely moving mice with chronically implanted electrodes. The brain monoamine neurotransmitters levels in mice were measured by high performance liquid chromatography-electrochemical detection. The spontaneous locomotor activity was decreased by 56.7% and 80.2% in H1208 (5 and 25 mg x kg(-1), ip) treated mice, respectively. The loss of righting reflex was directly induced in mice after H1208 (60 mg x kg(-1), ip) administration. The non-rapid eye movement sleep increased significantly by 131% and 259%, respectively, within 3 hours after H1208 (30 and 60 mg x kg(-1), ip) administration. However, the rapid eye movement sleep decreased significantly. The contents of DA in the striatum and cortex and 5-HT in the cortex decreased significantly. These results demonstrated that H1208 has potent sedative and hypnotic effects, which may be closely related to the decreased contents of DA and 5-HT in mouse brain.

Four kinds of ionic liquids [BMIM] Br, [BMIM] BF4, [BMIM] PF6, [HMIM] PF6 were used to analyze the content of oleanic acid and paeoniflorin in Paeonia lactiflora with ultrasonic-assisted extraction coupled with HPLC. The chromatographic column, Purospher star RP-C18 (4.6 mm x 250 mm, 5 μm), was used. Acetonitrile and water (90:10) as mobile phase was used to determine the content of oleanic acid with a gradient elution and flow rate at 1.00 mL · min(-1), detection wavelength at 210 nm, chromatographic column temperature at room temperature. Paeoniflorin content was determined using acetonitrile and water (18:82) as mobile phase with a gradient elution and flow rate at 1.00 mL · min(-1), detection wavelength at 250 nm, the chromatographic column temperature at room temperature. The result show that oleanic acid has the highest extraction yield when the conditions are solid-liquid ratio of 1:80 (g · mL(-1)), and the [BMIM] Br methanol solution concentration of 0.6 mol · L(-1). Under the optimal extraction conditions, the content of oleanic acid from 0.24 to 3.76 μg showed a good linearity (r = 0.9999), the average recovery was 97.20%. Paeoniflorin has the highest extraction yield when the conditions are solid-liquid ratio of 1:130 (g · mL(-1)), and the [C4 MIM] PF6 methanol solution concentration of 0.6 mol · L(-1). Under the optimal extraction conditions, paeoniflorin content from 0.42 to 4.20 μg showed a good lin- earity (r = 1.000), the average recovery was 98.84%. This method is simple and reliable, its repeatability is also very good. It has important significance in the study P. lactiflora of ionic liquid microextraction.
