Paeoniflorin is the main active ingredient of Chinese herbaceous peony. This study is to investigate the protective effect of paeoniflorin (Pae) on acute brain damage induced by lipopolysaccharide (LPS) in mice. The mice were randomly assigned to the normal control, model control (LPS), as well as groups of paeoniflorin and lipopolysaccharide (Pae + LPS). Then the mice were administered intraperitioneally with normal saline or Pae (10, 30 mg · kg(-1)) once daily for 6 d. One hour after intrapertioneally treatment on the seventh day, each group were injected LPS (5 mg · kg(-1)) to establish the endotoxin lipopolysaccharide inflammation model except the normal group. The mice were sacrificed after 6 h and the brain homogenates were prepared and measured. The malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), total antioxidant capacity (T-AOC), hydrogen peroxide (H2O2), succinatedehydrogenase (SDH), Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase were dectected by the colorimetric method. The levels of HO-1 and Nrf2 protein in subcellular fractions of brain tissue were detected by Western blot. The results demonstrated that the administration with paeoniflorin reduced the levels of the MDA production; significantly increase the activities of antioxidant enzyme (SOD and GSH-PX). In addition, paeoniflorin could enhance the total antioxidant capacity, decrease the level of H2O2, and increase the activities of SDH, Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase. Furthermore, paeoniflorin can increase the expression of HO-1 and activate the nuclear transfer of Nrf2. Taking together, these findings suggest that paeoniflorin alleviate the acute inflammation in mice brain damage induced by LPS, which is related with its antioxidant effect and improvement of energy metabolism.

Objective To investigate the clinicopathological features and prognostic factors in patients with low grade glioma. Methods Eighty- seven patients with low grade glioma confirmed by cytological examination were retrospectively analyzed. Results Among 87 patients, male accounted for 62.1%(54/87), and the average age was 36.2 years. The average followed- up time was 51.4 months (3-135 months), and 5 cases were lost in follow-up. The follow- up rate was 94.3% (82/87). The 3- year survival rate was 84.1%, and the 5- year survival rate was 66.7%. The 3- year survival rate was related to clinical symptoms, maximum diameter of tumor and the extent of resection (P<0.01 or<0.05);and the 5- year survival rate was related to years, Karnofsky score, clinical symptoms, maximum diameter of tumor, the pathology classification and extent of resection (P<0.05 or<0.01). Conclusions Low grade glioma is more common in male patients and patients under the age of 40 years. Age below 40 years, Karnofsky score ≥ 70 scores, only epilepsy symptom, tumor diameter below 6.0 cm, oligodendrogliomas, complete resection or subtotal resection are positive prognostic factors. Postoperative radiotherapy can reduce the rate of tumor progression.

Objective To evaluate the effect of co -administration of the loop diuretic furosemide (Fur) and kanamycin (KM ) in the rats in order to establish a reliable animal model of sensorineural hearing loss .Methods Thirty -two Sprague-dawley (SD) rats were randomly divided into 4 groups with 8 rats in each group .Rats in group A ,B and C received a single intraperitoneal injection of kanamycin sulfate (KM ,500 mg/kg) ,followed by an-other intraperitoneal injection of furosemide (Fur ,0 .2 ml/kg ) 30 minutes later .While ,rats in control group D re-ceived same doses of normal saline .Auditory brain responses (ABRs) were recorded at 1 ,7 and 14 day after the in-jections ,which were group A ,group B and group C ,respectively .Hair cell loss ,the spiral ganglions and microstruc-ture were observed by immunofluorescence and scanning electron microscopy .Results The ABR thresholds in group A ,B and C were significantly higher than that of in control group D (P<0 .05) .There were no differences of ABR thresholds among group A ,B and C(P>0 .05) .Immunofluorescence and scanning electron microscopy showed obvi-ous hair cell loss in the basal turn in each kanamycin groups ,with cilia disarrangement and fusion ,compared to the same areas in animals from the control group .The expression of cleaved caspase -3 significantly increased in each experimental group than that of in the control group(P<0 .05) .Conclusion Co -administration of furosemide and kanamycin intraperitoneally induces profound hearing loss in rats and is an effective method of establishing acute hearing loss model in animal experiments .

Objective To analyze effects of antithymocyte globulin(ATG) in preventing the occurrence of graft-versus-host disease(GVHD) in allogeneic stem cells transplantation. Methods Twenty-seven patients with leukemia were divided into two groups.The source of the transplantation donor and the type of acute leukemia were similar between the two groups,including HLA-sibling donors,HLA-unrelated donors and HLA-haploidentical donors.The 12 patients in group A adopted the classic method(CsA + MTX) to prevent GVHD.The 15 patients in group B adopted CsA + MTX +ATG to prevent the occurrence of GVHD. Results The 15 patients in group B have been all survived.Four of them presented Ⅱ0 acute GVHD(aGVHD),while the rest 11 patients only presented Ⅰ0 GVHD in approximately 30 d after transplantation with control very soon.In group A,Ⅳ? ultra-acute GVHD occurred in 3 HLA-haploidentical patients at day 7,9 and 10 after transplantation.One HLA-unrelated patient presented Ⅲ? aGVHD.The 4 patients above mentioned died due to pulmonary infection secondary to severe GVHD.The rest 8 HLA-sibling patients presented Ⅱ?-Ⅲ? aGVHD. ConclusionUsing ATG before allogeneic stem cells transplantation can efficiently prevent the occurrence of GVHD or relieve its severity.It can significantly diminish the transplantation related mortality rate.

Objective To evaluate the effect of digital subtraction angiography and transcatheter embolization for gastrointestinal hemorrhage.Methods Twenty patients with gastrointestinal hemorrhage received celiac arteries,superior mesenteric arteries and inferior mesenteric arteries angiography. Superselective angiography were performed when the arteries were suspicious by clinic or angiogrraphy.Ten patients with definite diagnosis and manifestation of hemorrhagic arteries by angiography were embolized after superseleetive catheterization with gelfoam particles,gelfoam particles and coils,polyvinyl alcohol particles. Results The positive signs were observed in 13 cases.The DSA features including contrast medium accumulation in the gastrointestinal tract outside vascular,aneurysm,tumorous vascularization and staining, artery affect and local vasospasm.The bleedings were stopped immediately in 8 patients.No rebleeding and intestinal ischaemia or necrosis were observed in 30 days.One patient died in the second day after embolization from multiple organ failure.Rebleeding occurred 3 days after embolization in another patient, and was recovered after surgical operation.Conclusion DSA is more effective for the diagnosis of gastrointestinal vascular malformation and tumors complicating acute bleeding.Transcatheter embolization is effective and safe to control the hemorrhage.

Objective To investigate the incidence of auditory nerve pathway injury complicated with cere- bral palsy(CP) and its related factors relationship between the incidence rate of it and sexes,classification and risk factors. Methods The clinical data of 272 children with CP,including the data of brainstem auditory evoked po- tentials,were retrospectively reviewed.The incidence of auditory nerve pathway injury and the related factors were analyzed.Results In the 272 CP children,the incidence of auditory nerve pathway injury was 29.8% (81:272), which had a significantly relationship with the clinical types of CP (P0.05).In addition,it was found that the pathological jaundice (OR=2.945,95% CI:1.649-5.260) and intrauterine infection (OR=3.319,95% CI:1.037-10.625) were significantly related to auditory nerve pathway injury. Conclusion The auditory nerve pathway injury is common in CP children,especially in those with athetosis and mixed CP.Pathological jaundice and intrauterine infection are the risk factors of auditory nerve pathway injury.

OBJECTIVETo clarify the role of waist circumference (WC) in estimating organ damage and assessing the prognosis in young and middle-aged patients with cardiovascular disease undergoing cardiac rehabilitation program (CRP).

METHODSWe recruited 147 young and middle-aged patients with cardiovascular disease to participate in the CRP for 4 or 5 weeks. The baseline clinical data and results of routine fasting blood test and ultrasonic cardiography were evaluated for these patients.

RESULTSWC had a linear correlation with the indices reflecting cardiac structure alteration (LVSd and LVPWd) of the patients after CRP but showed a negative correlation with their HDL-C levels. The fasting blood glucose (FBG) and serum uric acid (UA) levels showed a positive correlation with WC before CRP but not after CRP.

CONCLUSIONWC monitoring allows accurate assessment of organ damage in patients undergoing CRP after cardiovascular disease and has special value in evaluating the changes in cardiac structure and function.
