This study was aimed to investigate the anti-inflammatory, diuretic effect and acute toxicity of Herb of Lanceolate Sedge. The mice were randomly divided into 5 groups, which were the physiological saline group, aspirin group (0.05 g·kg-1), high dose (HD), middle dose (MD) and low dose (LD) of water extract of Herb of Lanceolate Sedge (10, 5, 2.5 g crude drug per kg) group. Intragastric administration of medication was given to mice once a day for 3 days. Auricular swelling induced by dimethyl benzene was used in the model establishment to calculate the swollen ear degree and the swollen inhibiting rate. And rats were randomly divided into 5 groups, which were the physiological saline group, aspirin group (0.05 g·kg-1), high dose (HD), middle dose (MD) and low dose (LD) of wa-ter extract of Herb of Lanceolate Sedge (10, 5, 2.5 g crude drug per kg) group. Intragastric administration of medi-cation was given to rats once a day for 5 days. Carrageenan induced paw edema was used in the model establishment to calculate the paw swollen rate. And rats were randomly divided into 5 groups, which were the physiological saline group, Furosemide tablets group (0.01 g·kg-1), high dose (HD), middle dose (MD) and low dose (LD) of water extract of Herb of Lanceolate Sedge (10, 5, 2.5 g crude drug per kg) group. Intragastric administration of medication was giv-en to rats once a day for 5 days. Water-loaded was used in the model establishment to calculate the 5-hour urine amount. The maximum tolerance dose (MTD) was used in the determination of the acute toxicity. The results showed that the three groups of HD, MD and LD of water extract of Herb of Lanceolate Sedge had obvious inhibiting effects on the swollen ear degree and the swollen inhibiting rate among mice, and the paw swollen rate of rats. It had signif-icant increasing effect on the 5-hour urine amount. The MTD of intragastric administration of water extract of Herb of Lanceolate Sedge was 640 g crude drug per kg for mice. It was concluded that Herb of Lanceolate Sedge dis-played obvious effects on anti-inflammatory and dieresis with low acute toxicity.

This study was aimed to establish a HPCE method for the content determination of hesperidin and phillyrin in Bao-He-W an (BHW). Fused silica capillary (75 cm í 50 μm) was employed and 30 mmol·L-1 borax so-lution (8% acetonitrile, pH9.64) was served as the running buffer. Other conditions were as follows: electrokinetic injection was 50 kPa í 20 s; analytical voltage was 20 kV; temperature was 20℃; and detection wavelength was 254 nm. The silica capillary was flushed with 0.1 mol·L-1 sodium hydrate and the running buffer for 10 min before each injection, respectively.

A quantitative analysis method of multi-components with a single marker (QAMS) for simultaneous determination of six marker compounds (one from phenolic acids and five from phthalides) in Chuanxiong Rhizoma was established by applying HPLC and using butylidenephthalide as the internal reference substance. And also the feasibility and accuracy of the established method for quality evaluation and application of Chuanxiong Rhizoma were investigated and validated. The analysis was performed with the mobile phase consisting of acetonitrile - 0.2% aqueous formic acid. The flow rate was 1.0 mL . min-1 and the column temperature was maintained at 30 °C. The detection wavelengths were set at 252 nm (for ferulic acid, Z-ligustilide, and butylidenephthalide) and 266 nm (for senkyunolide I, senkyunolide A, and coniferyl ferulate), separately, and 20 µL was injected for analysis with gradient elution. The results showed that there were no significant differences observed between the HPLC-QAMS method and the external standard method (RSD <5%). The relative correction factors were credible (RSD < 5%) in changed chromatographic conditions. The established HPLC-QAMS method can be accurately used for simultaneously evaluating and controlling the quality of Chuanxiong Rhizoma with multi-components.

Objective: To summarize the short-term clinical experience of minimally invasive direct cardiac surgery (MIDCS) with right anterolateral thoracotomy incision by closed cardiopulmonary bypass. Methods: A total of 42 patients received MIDCS in our hospital from 2013-09 to 2015-05 were summarized. There were 18 male and 24 female patients including 16 with atrial septal defect (ASD) repair, 4 with ventricular septal defect (VSD) repair, 16 with mitral valve replacement (MVR), 1 with mitral valve plasty (MVP) and 5 with aortic valve replacement (AVR). Direct cardiac surgery was performed by cardiopulmonary bypass through femoral artery-vein and right jugular vein annulations. A right anterolateral thoracotomy incision (length 3-5 cm) was made to enter the chest and complete the operation.

OBJECTIVE: To observe the short and long-term efficacy of quick repositioning maneuver for posterior semicircular canal benign paroxysmal positional vertigo (PC-BPPV) in different age groups. METHOD: The clinical data of 113 adult patients with single PC-BPPV who underwent quick repositioning maneuver from July 2009 to February 2015 were retrospectively analyzed. The quick repositioning maneuver was to roll the patient from involved side to healthy side in the coronal plane for 180° as quickly as possible. The patients were divided into 3 groups according to different ages: young group (< 45 years), middle-age group (45 ≤ age < 60 years) and old group (≥ 60 years). The short and long term outcomes of the three groups were observed. RESULT: The left ear was involved in 58 cases (51.3%) and the right ear in 55 cases (48.7%). The short term improvement rates of the young, middle-age and the old groups were 92.5%, 93.6% and 92.3% respectively, and the long term improvement rate was 90.0%, 85.1% and 73.1% respectively. There was no significant difference among the three groups in short and long term outcomes (P > 0.05). The recurrence rate of the three groups was 5.0%, 6.4% and 15.4% respectively, also no significant difference (P > 0.05). CONCLUSION The quick repositioning maneuver along the coronal plane for PC-BPPV has a definite effect for every age groups.
