AIM: To investigate the effect of lowering intraocular pressure ( IOP ) and side effect of travoprost ( TA ) on phacoemulsification and intraoclular lens ( IOL ) implantation in primary open-angle glaucoma ( POAG) .
METHODS: Patients with POAG already received surgery of phacoemulsification and IOL implantation were selected by randomized, single - blind, parallel group trial. TA was applied once a day in 43 patients (43 eyes) of treatment group and brinzolamide was used twice in 43 patients ( 43 eyes ) of control group. All patients were observed for 12wk. IOP, ocular symptom and adverse reaction etc. were observed.
RESULTS: The daily average IOP ( mean ± standard deviation) in the treatment group decreased from (24. 20±3.01)mmHg (1mmHg=0.133kPa) to (16.77±2.89)mmHg and that in the control group was from ( 23. 87±3. 47 ) mmHg to ( 18. 81± 3. 07 ) mmHg. IOP pre- and pro-treatment within two groups had significant difference ( P<0. 01), IOP between the groups at each time point had statistical difference (P<0. 05). Conjunetival congestion increased and itching in treatment group was obviously more serious than that in the control group, but the treatment could continue. No other ocular and systemic adverse events related to the drugs were found.
CONCLUSION: It is demonstrated that travoprost is highly effective and safe in reducing IOP in POAG already received surgery of phacoemulsification and IOL implantation.

Objective To investigate the association between resting heart rate(RHR)and dyslipidemia. Methods A total of 772 subjects(average age:40. 1 ± 11.8 years;male:74. 7%)were recruited by random sampling method from medical checkup population. The survey data included resting heart rate,blood lipid and other metabolic parameters. The subjects were divided into three groups according to the RHR,as RHR ＜ 70 bpm,70 bpm ≤ RHR ＜ 80 bpm,RHR ≥ 80 bpm groups. Results RHR were positively correlated with triglyceides (TG),as well as total cholesterol(TC)(r = 0. 316 and r = 0. 110 respectively,all P value ＜ 0. 05). Low RHR had no significant correlation with HDL-C or LDL-C. The prevalences of hypertriglyceridemia and hypercholesterolemia increased significantly with RHR elevation(χ2 = 7. 214 and 5. 285 respectively,all P value ＜ 0. 05). By logistic regression analysis,adjusted for BMI,gender,serum creatinine,serum uric acid,fasting blood glucose and age,we found that compared with RHR ＜ 70 bpm group,the odds ratio(OR)values for hypertriglyceridemia was 1. 540 (95%CI:1. 086-2. 185,P=0. 016)in 70 bpm≤RHR ＜80 bpm group and 1.640(95% CI:1.067 -2.523,P =0. 024)in 80 bpm ≤ RHR group,and the OR values for hypercholesterolemia was 1.197(95 % CI: 0.749 - 1.913,P=0.453)in70 bpm≤RHR ＜80 bpm group and 1.814(95% CI:1. 036-3. 177,P =0.037)in 80 bpm≤RHR group. Conclusions RHR is independently and positively correlated with the prevalence of hypertriglyceridemia and hypercholesterolemia and the blood levels of both lipid. RHR has no significant correlation with HDL-C or LDL-C level.

OBJECTIVETo discuss that pathogenesis evolvement regularity of Chinese miniature swine with phlege-stasis cementation syndrome of coronary heart disease.

METHODEighteen Chinese miniature swine were randomly divided to the normal control group, the model group and the Danlou tablet group, with six swine in each group. Except for the normal control group, all of the other groups were fed with high fat diet for two weeks. The coronary heart disease model with phlegm-stasis cementation syndrome was established by injuring left anterior descending artery with interventional balloons and continuously feeding with high fat diet for eight weeks. The levels of BMI, hemorheological parameters, lipids in serum and inflammatory cytokines were observed at the 0th (before the experiment), 2nd (before operation or drug administration), 6th (four weeks after drug administration) and 10th week (eight weeks after drug administration) of study. The levels of TG and TC in liver and the pathological changes in coronary artery tissues were also observed at the end of study.

RESULTCompared with the normal control group, the model group had showed significant increase in the levels of TC, TG, LDL-C and VLDL-C in serum (P < 0.01) from the second week to the end of the experiment, with notable rise in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1). At the 6th week, the levels of BMI and TG and TNF-alpha in serum significantly increased. At the 10th week, the levels of BMI and hs-CRP, IL-6 and TNF-alpha in serum significantly increased as well, with remarkable increase in coronary stenosis, intimal thickness and the ratio between intimal thickness and media thickness (P < 0.05 and P < 0.01), and significant rise in TC and TG in livers (P < 0.01). Compared with the model group, the Danlou tablet group showed obvious reduction in severity of coronary artery lesion, intimal thickness and lumen stenosis ratio and ratio between intimal thickness and media thickness (P < 0.01), BMI, TC, TG, LDL-C and VLDL-C in serum, TC and TG in liver, as well as hs-CRP, IL-6 and TNF-alpha levels in serum (P < 0.05 and P < 0.01), with notable decline in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1).

CONCLUSIONThe interaction of phlegm, blood stasis and toxin syndromes helps promote the progress and development of AS plaques, which is the key pathogenesis of phlegm-stasis cementation syndrome in coronary heart disease.

Objective To understand the expiration date of alcohol-based hand disinfectant after it is opened for use,and provide reference for rational clinical application of alcohol-based hand disinfectant.Methods 20 bottles of the same brand alcohol-based hand disinfectant which opened at the same time by the clinical departments were selected as the study object,hand hygiene compliance in theses departments ranked fourth from the end in the hospital,specimens were taken on the first day after opening,and repeated every 10 days until the disinfectant was used up.Hand specimens were also taken after disinfected by disinfectant.Qualified condition of disinfectant and hand specimens was detected.Results A total of 98 disinfectant specimens were collected,by naked eye observation,20 bottles of alcohol-based hand disinfectant were free of discoloration,precipitation,and suspended matter during the whole study period.The qualified detection rates of alcohol-based hand disinfectant within 60 days after opening were all 100%.44 hand specimens were taken and detected after disinfection,3 of which were unqualified(all were disinfected by alcohol-based hand disinfectant 50 days after opening),then detected again after disinfected by the same batch of disinfectant,all were qualified,which suggested that unqualified detection result of hand specimens was not due to disinfectant.Conclusion Alcohol-based hand disinfectant still has a good bactericidal effect on the sixth day after opening.

To study bioadhesive property of carbomer 934 in dog alimentary tract, carbomer 934 and ethylcellulose were radiolabelled with technetium-99 m. The gastrointestinal emptying rate of these materials was measured by the technique of gamma scintiscan. The results showed that the empty rate of adhesive material (carbomer 934) was remarkably slower in dog alimentary tract compared to nonadhesive material (ethylcellulose). It is concluded that, in dog, the interaction between gastrointestinal mucus layer and adhesive material or nonadhesive material was significantly different. Carbomer 934 had stronger bioadhesive property in vivo than that of ethylcellulose.
