Objective:To investigate the infuluence of electroacupuncture on blood lipid and liver function in nonclcoholic fatty liver rats. Methods:Thirty-three male SD rats were randomly divided into 2 groups:normal control group (n=11,fed with normal food) and non-alcoholic fatty liver model group (NAFLD) (n=23,fed with high-fat food). Eight weeks later 1 rats were randomly selected from the normal control group and 2 rats were randomly selected from the NAFLD group and were killed to undergo pathological examination of the liver. When the establishment of experimental model of NAFLD rats was confi rmed the remaining 20 NAFLD rats were sublishment into 2 equal subgroups:NAFLD control group to be fed continuously with high-fat food ,acupuncture treatment group (to fed continuously with high-fat food). Take Zusanli,Hong Leong,Sanyinjiao,Taichong points,electroacupuncture -spacing parameters,2Hz frequency,intensity 4mV to the appropriate vibrating slightly lower limb. By the end of the 12th week,all rats were killed to isolate the samples of test the levels of serum total cholesterol (TC),serum triglyceride (TG),high-density lipoprotein cholesterol (HDL-L),low-density lipoprotein cholesterol (LDL-CH),liver index,Valley serum ALT(ALT),Aspartate aminotransferase (AST),and liver pathology. Results:Treatment of rats --serum total cholesterol (TC),serum triglyceride (TG),low-density lipoprotein cholesterol (LDL-CH),liver index,Valley serum ALT(ALT),Aspartate aminotransferase (AST) were significantly lower than those of NAFLD control group (P

Objective To assess the efficiency of algae extermination by the combined copper electrolysis technology. Methods The combined copper electrolysis technology and copper sulphate were used to treat the Synechocystissp strain PCC6803 in the steady stage of culture in different time and the efficiency of algae extermination was assessed. Results No alga in the water sample was detected after 0.5 and 1 hour of treatment with copper electrolysis technology and copper sulphate respectivly as the concentration of Cu2+ was at 0.3 mg/L. The extermination rate of algae was 80.75% after 12 days of treatment of combined copper electrolysis. This technology could effectively decrease the turbidity, smell, COD, ammonia nitrogen and increase the dissolved oxygen in the treated water. Conclusion The Cu2+ released by copper electrolyzing has a stronger efficiency of algae extermination compared with copper sulfate. The combined copper electrolysis technology will be a satisfactory method for algae extermination in the landscape water.

Objective To expore the clinical therapeutic effect of allergic rhinitis using endoscopic more nasal structures orthopedic surgery combined with steroid nasal spray. Methods Sixty allergic rhinitis patients accompanied by deviation of nasal septum, middle turbinate lesions, or/and inferior turbinate lesions, were divided into two groups: observation group with 30 cases, applying endoscopic more nasal structures orthopedic surgery combined with steroid nasal spray (mometasone furoate nasal spray) during perioperative period; control group with 30 patients, only applying steroid nasal spray (mometasone furoate nasal spray). Long-term effect was compared between two groups. Results Sixty cases were followed up for 1 year. The total effective rate was 90.0%(27/30) in observation group,22 cases of significant effect, 36.7% (11/30) in control group,3 cases of significant effect. The total effective rate had significant difference between two groups (P<0.01). Conclusion Using endoscopic more nasal structures orthopedic surgery combined with steroid nasal spray (mometasone furoate nasal spray) to treat allergic rhinitis has good long-term effect.

BACKGROUND: Endothelin(ET) -1 is a peptide with potent actions on blood vessels and nerve system. Its expression increases in the central nervous system(CNS) in a variety of pathological conditions, inducing harmful effects on the nervous tissue. However it is not clearly elucidated whether the over-expressed ET-1 can directly induce neuronal apoptosis.OBJECTIVE: To investigate whether ET-1 can directly induce apoptosis in primarily cultured brain neurons of rat, and which ET receptor subtype(s) is involved in this action.DESIGN: Completely randomized and controlled experimental study based on cells.SETTING: Neurological department in a university hospital, pathological department of a university and laboratory center of tissue transplantation and immunology, life science and technology college.MATERIALS: This study was completed in the Pathology Department, the Institute of Tissue Transplantation and Immunology, the Life Science and Technology College of Jinan University. The subjects were primarily-cultured neurons obtained from cerebral cortex of newborn rats that were provided by the Experimental Animal Center of the Medical College, Sun Yat-sen University.INTERVENTIONS: After culturing for five days, the neurons were treated with ET-1 (0. 2 nmol/L and 20 nmol/L) for 24 hours. Apoptotic neurons were semi-quantitatively measured with Annexin V and Hoechst 33258 staining respectively. ET-1(20 nmol/L), with BQ123(a selective antagonist for ET receptor A, 1 mmol/L) or with BQ788(a selective antagonist for ET receptor B, 1 mmol/L), was added respectively into the cultures simultaneously. And the apoptotic neurons were quantitatively measured with flow cytometry 24 hours later. Equal amount of PBS, instead of ET-1, waw added into the control subjects.MAIN OUTCOME MEASURES: The effect of ET-1 on apoptosis rate of cultured rat cortical neurons, and the ET receptor subtypes involved in this action.RESULTS: Twenty-four hours after treated with 0.2 nmol/L ET-1, the Annexin-V, and Hoechest 33258 positive stained cell rates[ (23.00 ± 9.96)%,(9.82 ±0.95)% ] were of no difference as compared with those of the controls[ (13.50 ± 3.35)%, (8.21 ± 2. 17)% ]. By contrast, after incubation with the higher dose of ET-1 (20 nmol/L), significant higher rate of apoptosis was measured in Annexin V staining[(50.50 ± 10.78)%, P=0.01, n=4] and Hoechest 33258 staining[(13.78±1.52)%, P= 0. 000, n = 8] . Analyzed with flow cytometry, the apoptosis rate was (0.20±0. 15)% in the control group, (26. 11 ±3.28)% in 20 nmol/LET-1 group, and(13.58 ±4. 92)% in BQ123 +ET-1 and(9.99 ±3.30)% in BQ788 +ET-1 respectively, indicating that BQ123 and BQ788 partially-blocked the apoptosis effect of ET-1 on. cultured neurons(BQ123 + ET-1 vs ET-1, P = 0. 005; BQ788 + ET-1 vs ET-1, P = 0. 001, n = 4, respectively).CONCLUSION: The higher dose of ET-1 (20 nmol/L) can directly induce apoptosis of primarily-cultured cerebral neurons of rats. The effect of ET-1 inducing neuronal apoptosis may be mediated via both ET receptors A and B.
