To study the protective effect and the mechanism of asiatic acid (AA) from Potentilla chinensis on alcohol hepatic injury in rats. Male Wistar rats were randomly divided into six groups: the normal control group, the AA control group (8 mg · kg(-1) AA), the model group (5.0-9.0 g · kg(-1) alcohol) and high, medium and low-dose AA-treated groups (alcohol + 8, 4, 2 mg · kg(-1) AA). Each group was orally administered with the corresponding drugs once a day for 24 weeks. Approximately 1. 5 hours after the final administration, all rats were killed, and their blood samples and hepatic tissues were collected. The AST and ALT in rat serum and the contents of MPO, TNF-α, IL-1β, SOD, GSH-Px, GSH-Rd and MDA in hepatic tissues were detected. The expressions of NF-κB, TLR4, CD14, MyD88, TRIF and protein expression in hepatic tissues were measured by western blot. The pathological changes in liver tissues were observed by histological examination. The results showed that compared with the model group, the AA-treated groups showed significant decreases in serum ALT, AST and MDA and increases in the activities of SOD, GSH-Px, GSH-Rd and MPO. Moreover, AA markedly inhibited the expressions of TNF-α, IL-1β, TLR4, CD14, MyD88 and NF-κB. The histological examination showed alleviated hepatic issue ijury to varying degrees. In short, asiatic acid (AA) from P. chinensis could protect alcohol-induced hepatic injury in rats. Its mechanism may be related to the inhibition of NF-κB inactivation and the reduction of inflammatory response.

OBJECTIVETo observe the effect of sesamin (Ses) on pulmonary vascular remodeling in rats with monocrotaline ( MCT)-induced pulmonary hypertension (PH).
METHODTotally 48 male Sprague-Dawley (SD) rats were fed adaptively for one week and then divided into the normal control group, the MCT group, the MCT +Ses (50 mg x kg(-1)) group and the MCT + Ses (100 mg x kg(-1)) group, with 12 rats in each group. The PH rat model was induced through the subcutaneous injection with MCT(60 mg x kg(-1)). After the administration for four weeks, efforts were made to measure the right ventricular systolic pressure( RVSP) and mean pulmonary artery pressure (mPAP) through right jugular vein catheterization, and isolate right ventricle( RV) and left ventricle( LV) +septum (S) and measure their length to calculate RV/ ( LV + S) and ratio of RV to tibial length. Pathologic changes in arterioles were observed by HE staining. Masson's trichrome stain was used to demonstrate changes in collagen deposition of arterioles. The alpha-smooth muscle actin (alpha-SMA) expression in pulmonary arteries was measured by immunohistochemisty. The total antioxidative capacity (T-AOC) and malondialdehyde (MDA) content in pulmonary arteries were determined by the colorimetric method. The protein expressions of collagen I, NOX2 and NOX4 were analyzed by Real-time PCR and Western blot.
RESULTAfter the administration for 4 weeks, Ses could attenuate RVSP and mPAP induced by MCT, RV/ (LV + S) and ratio of RV to Tibial length, alpha-SMA and collagen I expressions and remodeling of pulmonary vessels and right ventricle. Meanwhile, Ses could obviously inhibit the expressions of NOX2, NOX4 and MDA content and increase T-AOC.
CONCLUSIONSesamin could ameliorate pulmonary vascular remodeling induced by monocrotaline in PH rats. Its mechanism may be related to expressions of NOX2 and NOX4 expression and reduction in oxidative stress injury.

Metastatic epidural compression of the spinal cord is a significant source of morbidity in patients with systemic cancer. With improvment of oncotheray, survival period in the patients is improving and metastatic cord compression is en- countered increasingly often. Surgical management performed for early circumferential decompression for the spinal cord com- pression with spine instability, and spine reconstruction performed. Patients with radiosensitive tumours without spine instabili- ty, radiotherapy is an effective therapy. Spinal stereotactic radiosurgery and minimally invasive techniques, such as vertebro- plasty and kyphoplasty, percutaneous pedicle screw fixation, radiofrequency ablation are promising options for treatment of cer- tain selected patients with spinal metastases.

Objective To discuss the clinical characteristic and diagnosis of children with moyamoya disease(MMD).Method The clinical features of 4 children with MMD were analyzed.Results The early clinical spectrum in children with MMD was transiently ischemic attack,and presented with injured neuron manifestations after some seizures,such as paralysis,extremity sensory disturbance, seizure of epilepsy,language disorder,involuntary movement and psychotic symptoms.Magnetic resonance angiography(MRA) and DSA demonstrated multiple cerebral vessels occlusion or stenosis and moyamoya vessels,so MRA became the first choice for detec- ting MMD.Conclusions The clinical symptom and neuron symptom of children MMD may not be typical,and it is easily misdiagnosed.Its correct diagnosis depends on thorough physical examination,appropriate laboratory tests,and the general knowledge of this disease.

Objective To make a reasonable evidence-based nursing scheme for the oxygen non-humidified of continuing nasal cannula oxygen therapy. Method Adopting the JBI clinical evidence application system, make sure the evidence baseline investigated before application, used during clinical application, and reviewed after application. Based on the now available best evidence, making examination standard and apply it to clinical care. During the application of evidence, 81 continuing low-flow (oxygen flow≤4L/min) nasal cannula oxygen patients were taken. Making assessment on the experiment group(oxygen non-humidified) and control group (oxygen humidified) in three aspects: the comfort level and effect of oxygen therapy, and humidification bottles contamination. Results During the application of evidence, the difference between experiment group and control group shows no statistical significance (P>0.05);the experiment group in oxygen therapy operating time was (162.93±40.18) s, the control group operating time was (258.60 ± 56.97) s, the difference of two groups in shows statistical significance (t=8.752, P<0.01). Conclusion The continuing low-flow (oxygen flow≤4L/min) nasal cannula oxygen therapy do not need humidification. And the clinical application of this best evidence standardizes the clinical nurses oxygen nursing behavior, reduces the nursing cost and enhances the quality of clinical nursing.
