ABSTRACT
Objective To study the variation of the level of lipids, OX-LDL and vascular intimal injury in diet-induced hyperlipidemic and chronic Cpn-infected mice and the interventional functions of berberine. Methods C57BL/6J mice were divided randomly into 6 groups: Berl group, Ber2 group, azithromycin group, atorvastain group, cholesterol + Cpn group, and normal group. Mice were inoculated intranasally with Cpn for three times, every 2 weeks over a 6-week period and feeding with high cholesterol diet. Berl group was administrated with berberine at the beginning of CPn infecting, while ber2 group, azithromycin group and atorvastain group were administrated with the drug after the 3rd CPn infecting. The serum index, HE dye of the aortas and electron microscopic examination were observed. Results Lipids disorder, increased level of OX-LDL and vascular intimal injury were found. The level ofTC, LDL, TG OX-LDL in Bet group, azithromycin group, and atorvastain group declined in different extent. Conclusion Berberine has effects of regulating lipids disorder, OX-LDL and protecting vascular intima of diet-induced hyperlipidemic and chronic Cpn-infected mice.
ABSTRACT
<p><b>OBJECTIVE</b>To study the influence of Chlamydia pneumonia (Cpn) infection on haemorheology and atherosclerosis and the intervention of Huanglian Jiedu decoction (HJT).</p><p><b>METHOD</b>At the beginning of the experiment, all the sixty New-Zealand rabbits were token blood to test Cpn IgG and all the results were negative. Eight New-Zealand rabbits were randomized into normal group F, and all other rabbits were fed with forage containing 2.5 g x kg(-1) cholesterol and infected with Cpn via nasophrynx for three times during 6 weeks. At the end of the sixth week, forty-four rabbits with serum Cpn IgG positive were randomized into four groups: Group A treat with HJD 2 g x kg(-1) d(-1) by gastric gavage, group B with HJT 1 g x kg(-1) x d(-1), group C with azithromycin 20 mg x kg(-1) x d(-1), model group D with normal saline for six weeks. Group E was set up in eight rabbits with serum Cpn IgG negative and served as the control. At the end of 18th week, blood was token from middle ear artery to test haemorheology such as whole blood viscosity, plasma viscosity, haematocrit, erythrocyte aggregation index (EAI), erythrocyte rigidity index (IRI), and erythrocyte deformability index (EDI). After that, all the rabbits were executed and the pathological features of aorta tissue were observe under microscope.</p><p><b>RESULT</b>Haemorheological disorder and atherosclerotic changes were obvious in both group D and E. while maximum intimal thickness (MIT) (23.65 +/- 8.19 vs 12.76 +/- 4.06), atherosclerotic damage percentage (P(LCI)) (41.08 +/- 12.51 vs 22.43 +/- 9.45), plaque area index (I(PA)) (9.57 +/- 1.82 vs 2.84 +/- 0.25) in group D was much higher than that in group E (all P < 0.01). Compare with group D, haemorphological disorder and atherosclerotic changes were much improved in group A, B and C. MIT (6.45 +/- 1.27 vs 23.65 +/- 8.19), (P < 0.01), P(LCI) (22.39 +/- 6.74 vs 41.08 +/- 12.51), (P < 0.05) and I(PA) (1.44 +/- 0.33 vs 9.57 +/- 1.82), (P < 0.01) in group A was much lower than that in group D. And MIT (12.65 +/- 3.63 vs 23.65 +/- 8.19), (P < 0.01) and I(PA) (4.43 +/- 1.17 vs 9.57 +/- 1.82), (P < 0.05) in gruoup B was much lower than that in group D too.</p><p><b>CONCLUSION</b>Cpn infection could aggravate the haemorheology disorder in cholesterol-supplemented-diet rabbits, and both antidotal decoction of Coptis and azithromycin can alleviate it.</p>

BACKGROUND: Brain-awakening nasal sprayer is composed of many herbs,such as Chuanxiong and Shichangpu, which were regarded by "Shennong Bencaojing" as having the function of "preventing stroke in the brain".OBJECTIVE: To observe the changes of free radicals and nitric oxide synthase in rat brain following focal ischemic-reperfusional injury due to brain-awakening nasal sprayer intervention and compare with that due to classical nimodipine.DESIGN: A randomized controlled study.SETTING: Department of internal medicine of a hospital affiliated to a traditional Chinese medical university.MATERIALS: Seventy adult male Wistar rats of clean grade, were randomly divided into seven groups: brain-awakening nasal sprayer of higher dosage group, moderate dosage group, lower dosage group, nimodipine intraperitoneal injection group, physical saline nasal sprayer group, menstruum nasal sprayer group, and sham operation group with 10 rats in each.METHODS: Focal brain ischemia-reperfusion model was established by blocking the left cerebral middle artery in rats of all the groups except sham operation group. Three days before model establishment and during reperfusion, rats were given different dosages of brain-awakening nasal sprayer composed of Chuanxiongqin and Shichangpu of 5.4, 2.7, 1.08 mg/(kg · d) and 1.35, 0. 54, 0.27 g/(kg· d), respectively, three times a day; which was replaced by physical saline and menstruum nasal sprayer of 0. 18 mL/ (kg · d),three times a day in physical saline nasal sprayer group and menstruum nasal sprayer group; rats in nimodipine intraperitoneal injection group received intraperitoneal injection of nimodipine by 0. 8 mg/(kg · d) twice a day. Rats in sham operation group were routinely raised. The content of prodialdehyde, superoxide dismutase and nitric oxide synthase were measured with colorimetric method.MAIN OUTCOME MEASURES: ① The changes of prodialdehyde content, superoxide dismutase and nitric oxide synthase activity in rat brain following focal ischemic-reperfusional injury in groups of different dosage of brain-awakening nasal sprayer and other groups. ② Comparison between different dosage brain-awakening nasal sprayer intervention groups and nimodipine intraperitoneal injection group.RESULTS: Eight rats died during model establishment and the other 62 rats entered the results analysis. ① Content of prodialdehyde: It was significantly lower in higher dosage group and nimodipine intraperitoneal injection group than in physical saline nasal sprayer group [ (0.92 ± 0. 32), (0. 87 ± 0. 39)vs(1.35 ±0. 34) μmol/g, P ＜ 0.05], but there was no difference between higher dosage group and nimodipine intraperitoneal injection group. ② Activity of superoxide dismutase: It was obviously higher in higher dosage group and nimodipine intraperitoneal injection group than in physical saline nasal sprayer group[ (35.64 ± 11.67), (33.88 ± 7. 15) vs(20. 70 ± 3.88) NU/mg,P ＜ 0. 05 ], but no difference could be observed between higher dosage group and nimodipine intraperitoneal injection group. ③ Activity of nitric oxide synthase and superoxide dismutase: It was found obviously higher in higher dosage group and nimodipine intraperitoneal injection group than in physical saline nasal sprayer group[ (4.64 ± 1.22), (5.00 ± 1.10) vs (3.08 ± 1.12) mkat/g, P ＜ 0.05], but no difference could be observed between higher dosage group and nimodipine intraperitoneal injection group.④ The activity of nitric oxide synthase and superoxide dismutase slightly increased while prodialdehyde slightly decreased in moderate dosage group,lower dosage group and menstruum nasal sprayer group, which did not differ significantly from physical saline nasal sprayer group.CONCLUSION: Brain-awakening nasal sprayer intervention exerts multiple effects such as preventing lipo-peroxidation following brain ischemic- reperfusional injury, in addition to suppressing prodialdehyde production, attenuating injury induced by free radicals and increasing nitric oxide synthase activity, thereby playing a similar role to nimodipine in protecting against brain ischemic-reperfusionaldamage

ABSTRACT
Objective To assess the effect of sodium hyaluromate (HA) on degenerative disorders of the knee joint (KJ). Methods A prospective randomized controlled clinical trial was conducted. The experimental group received injections in the compartments of the involved KJ with 1% HA 20mg, whereas the control group received prednisolone (PS) of 75mg once a week with five injections as one course. One week before and after the treatment , clinical symptoms, amount of interleukin-6 (IL-6) and total protein of synovial fluid were measured and compared. Results Both drugs could relieve the clinical symptoms of KJ degenerative disorders. In HA group, marked improvement rate was 52.78% and failure rate was 2.86%, whereas marked improvement rate was 39.29% and failure rate 17.86% in PS group. The declined levels of IL-6 in synovial fluid were notably greater in HA group than those in PS group. Conclusion Intra-articular injection of HA is effective and safe in treating KJ dgenerative disorders with mild adverse reactions.
