Objective To investigate the antimicrobial properties of human amniotic homogenate supernatant (HAHS) in order to found a theoretical base for the use of human amniotic membrane in ophthalmological field. MethodsFresh human amniotic membranes were used to make HAHS and acellular amniotic membranes. Then, we observed their antimicrobial effects and antimicrobial spectrums, compared the antimicrobial capacity with 10 commonly used antibiotics in eyes, and investigated the effects of time, temperature and pH value on the antimicrobial capacity. Finally, transmission electron microscopy (TEM) was used to explore the possible targeting site of the antibiosis. ResultsHuman amnion membrane contained antimicrobial components locating in its epithelial cells. HAHS had a broad antimicrobial spectrum and was steady in nature. Its antimicrobial capacity was stronger than those of sulfasulfonamide, chloromycetin and cefuroxime sodium. TEM indicated that the antimicrobial effect were exerted through plasma membrane of microorganism. ConclusionHAHS can be an effective and convenient treatment for ocular surface infectious diseases. Traditional amnion transplantation should employ fresh human amniotic membranes containing complete epithelial lamina to reconstruct the ocular surface.

Objective To observe clinical curative effect of acupuncture combined with western medicine in treating acquired paralytic strabismus.Methods Randomly divided 60 patients with acquired paralytic strabismus into a treatment group and a control group,with 30 cases in each group.The control group accepted compound anisodine injection for subcutaneous injection beside superficial temporal artery and oral administration of neurotrophic drugs.The treatment group accepted acupuncture treatment in addition to the treatment of the control group.Both groups were treated for 4 weeks.Before and after treatment,measured the ocular symptom scores,including eye position deviation,eyeball movement obstacle,diplopia,the first squint angle being greater than the second,compensatory head posture and evaluated the clinical curative effect.Results The clinical curative rate in the treatment group was 40.0％ and the total effective rate was 93.4％,which in the control group were 10.0％ and 66.7％ respectively.The total effective rate and curative rate in the treatment group were significantly higher than those in the control group (P＜ 0.05).After treatment,the improvement in the total ocular symptom score and diplopia,deviation of eye position,eyeball movement disorder scores were superior to those in the control group (P ＜ 0.05).Conclusion Acupuncture combined with western medicine was superior to simple western medicine in treating acquired paralytic strabismus,and could significantly improve the eye symptom.

OBJECTIVE:To observe the efficacy and safety of eprosartan in the treatment of hypertensive patients with coro-nary heart disease. METHODS:160 hypertensive patients with coronary heart disease randomly divided into observation group and control group. All patients were given aspirin,nitroglycerin,low molecular weight heparin,statins and other conventional treat-ment;control group was additioanlly given 50 mg Losartan potassium tablet,orally,once a day. Observation group was additional-ly given 600 mg Eprosartan tablet,orally,once a day. The treatment course for both groups was 6 months. Clinical efficacy,sit-ting systolic blood pressure and diastolic blood pressure,alanine aminotransferase(ALT),aspartate aminotransferase(AST),urea (UREA),creatinine(Cr),uric acid(UA),total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol (LDL-C),the Mini-Mental status (MMSE) scale and activities of daily living (ADL) scale scores before and after treatment and incidence of adverse reactions in 2 groups were observed. RESULTS:There was no signifi-cant difference in the total effective rate between 2 groups(P>0.05). After treatment,the sitting systolic blood pressure and diastol-ic blood pressure,MMSE and ADL scale scores in 2 groups were significantly lower than before,and sitting systolic blood pres-sure in observation group was lower than control group,the differences were statistically significant(P<0.05),and there were no significant differences in sitting diastolic blood pressure,MMSE and ADL scale scores between 2 groups(P>0.05),and no signifi-cant differences in ALT,AST,UREA,Cr,UA,TC,TG,HDL-C and LDL-C between 2 groups before and after treatment(P>0.05). There were no obvious adverse reactions during treatment. CONCLUSIONS:Eprosartan can effectively reduce sitting systol-ic blood pressure in hypertensive patients with coronary heart disease,and improve cognitive function,with good safety.

OBJECTIVE:To study the effects and mechanism of propranolol on the myocardial abnormal electrophysiology sta-tion in diabetic model rats. METHODS:SD rats were randomly divided into normal control(normal saline)group,diabetic(nor-mal saline)group,PD98059(ERK inhibitor,10 mg/kg)group and propranolol low-dose,medium-dose and high-dose(1,20,50 mg/kg)groups,with 8 rats in each group. Except for normal control group,rats were given alloxan(20 mg/kg)intravenously via tail vein to induce diabetic model. They were given relevant medicine intragastrically,once a day,for consecutive 42 days. The car-diac index,electrocardiogram and action potential durations (APD) of rats were analyzed;the expression of TNF-α,IL-2,IL-6 and IL-10 protein in serum were detected,and the expression of Ras,Raf,ERK kinase(MEK)and ERK1/2 in myocardial tissue were detected. RESULTS:Compared with normal control group,cardiac index increased in diabetes group;heart rate decreased;QT interval and APD were prolonged;the relative expression of TNF-α,IL-2,IL-6,IL-10,Ras,Raf,MEK and ERK1/2 protein increased (P<0.01). Compared with diabetes group,cardiac index decreased in propranolol medium-dose and high-dose groups and PD98059 group,heart rate increased,QT interval and APD were shortened;the relative expression of TNF-α,IL-2,IL-6, IL-10,Ras,Raf,MEK and ERK1/2 protein decreased(P<0.05 or P<0.01). CONCLUSIONS:Propranolol can improve myocar-dial abnormal electrophysiology station of diabetic model rats by down-regulating inflammatory reactions in serum and inhibiting the activation of MEK/ERK signaling pathway.

OBJECTIVETo reveal the quality variation of polysaccharides, triterpenoids and proteins in spores and fruiting bodies of Ganoderma lucidum from producing areas, different varieties, harvesting parts and periods, and wall-breaking treatments.

METHODSpores and fruiting bodies from varieties of Longzhi No. 1 and Hunong No. 1 were collected as test samples, together with wall-broken spores sold in domestic main producing areas. The anthrone-sulfuric acid colorimetric method was used to determine the content of total polysaccharides. The vanillin-glacial acetic acid-perchloric acid colorimetric method was used to determine the content of total triterpenoids. The Lowry method was used to determine the content of total proteins.

RESULTThe content ranges of total polysaccharides, total triterpenoids, and total proteins from 6 domestic main producing areas were 0.40% - 2.25%, 1.36%-3.15% and 0.74% -1.91% respectively. The content ranges of total polysaccharides, triterpenoids, and proteins in the fruiting bodies from 2 varieties cultured in Zhejiang were 0.25% -1.42%, 0.44% -1.42% and 1.82% -3.67% respectively. In addition, the ranges of samples from wall-unbroken spores were 0.41% - 0.91%, 0.09% - 0.12%, 0.78% - 0.90% respectively and wall-broken spores are 1.03% - 2.25%, 1.89% - 3.15%, 0.96% - 1.04% respectively.

CONCLUSIONThere are significant differences in the contents of main chemical ingredients of wall-broken G. lucidum spores saled in the markets. The samples from Zhejiang contain high content of total polysaccharides and triterpenoids, and samples from Fujian contains more proteins. Between the 2 major varieties cultured in Zhejiang, Longzhi No. 1 contains higher content of triterpenoids, but Hunong No. 1 has more polysaccharides. Contents of triterpenoids and polysaccharides from wall-broken spores are much higher than those of fruiting bodies. The stipes from fruiting bodies contains more polysaccharides than those of the pileus, while the triterpenoids contents are higher in the pileus than stipes. The pileus and stipes collected in the second year contain higher content of polysaccharides than the first year's samples, but the contents of triterpenoids are lower. Wall-breaking treatment would significantly improve the extraction and dissolution rate of total triterpenoids and polysaccharides.
