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.

Objective To study changes in ACE, LDH and AKP in BALF and blood after rapid decompression in rabbits. Methods Thirty healthy New-Zealand rabbits were randomly divided into low decompression group and rapid decompression group. The respective activity of ACE, LDH and AKP in BALF and blood of rabbits was measured. Results Various degrees of increase in activity of ACE, LDH and AKP in BALF were observed after rapid decompression. Conclusion The simultaneous enhancement of activity of these enzymes suggest that there was injury to the lung consistent with the degree of injury after rapid decompression.

Objective To research the relationship between quality of life among the elderly with chronic periodontitis (CP) and the severity of CP.Methods A total of 471 elderly patients seeking treatment in the affiliated Stomatology Hospital of Kunming Medical University from September 2013 to January 2014 and their companions were investigated using the questionnaire according to the Chinese version of the Oral health Impact Profile-14.Those who diagnosed with CP were separated into two groups according to Community periodontal index (CPI) through periodontal examination.Group A was diagnosed with the early CP,and Group B was diagnosed with the late CP.Database was established by Epidata and statistical analysis was performed by SPSS.Results A total of 237 elderly patients with early CP and 139 with late CP were recorded.The mean OHIP-14 scores of the former were 14.36 ± 6.67,and the score of the later were 15.65 ± 7.12 relatively.The two groups who lived through negative effects were compared.The results suggested in the 14 items of OHIP-14.The statistical significance existed in the following 4 items,obvious pain appeared,uncomfortable when eating anything,unsatisfied with own diet,become easy to lose one's temper to others (P＜0.05).Conclusion OHR-QOL of elderly patients with the late CP is lower than that of those with the early CP.

Modeling methodologies developed for studying pharmacokinetic(PK)/pharmacodynamic(PD) processes confront many challenges related in part to the severe restrictions on the number and type of measurements that are available from laboratory experiments and clinical trials, as well as the variability in the experiments and the uncertainty associated with the processes themselves. Bayesian methods have provided a framework for PK/PD modeling and drug development that can address some of the above-mentioned challenges. This paper presents two illustrations of the application of Bayesian methods: the first involves a population modeling study of the cellular kinetics of the antiretroviral compound Lamivudine in the PBMCs of HIV-1 infected adolescents; the second uses a population mixture modeling approach to identifying hidden subpopulations that can not be identified by available measured covariates.

The nutritional value of bread fortified with zinc, lysine, iron, and calcium was evaluated by biological method. The amount of the supplemented lysine, iron, calcium and zinc in the experimental diet was 0.3%, 0.008%, 0.3% and 0.008% respectively.32 Wistar rats were devided randomly into 4 groups; the control group was fed with ordinary bread and the other three groups were fed with bread fortified with lysine, Fe and Ca, or Zn or lysine, Ca, Fe and Zn respectively. All the rats in each group took thier respective diet and drank distilled water ad libitum.The results indicated that the body weight of the group fortified with zinc alone was increased more fast at the first two weeks, and then slow down, finally, slower than the control group obviously. The increase of body weight, FE, PER, NPU, BV, weight and length of long bones, iron status in the group fortified with lysine, iron, and Ca combind were better than the control group. The group, however, fortified with lysine, Fe, Ca and Zinc combined was the best among these four groups. It promoted the growth of the rats markedly and did not impede the utilization of iron, calcium and copper as well.

ObjectiveTo investigate the therapeutic effectiveness of defibrase in treating penumbra and reperfusion.MethodsIntraluminal suture method was used to develope reversible middle cerebral artery occlusion(MCAO). Rats were subjected to MCAO 3 hours followed by reperfusion for 3, 6, 24, 72 hours, and to MCAO 6 hours followed by reperfusion for 3, 6, 24 hours. The treatment groups rats were injected intravenously defibrase at 0.5 hour before reperfusion. Meanwhile, the control group received normal saline. Clinically Neurological Deficits Scale were evaluated every day. Infarction volume was measured by using 2,3,5-triphenyltetrazolium chloride staining. Pathologic change were examined microscopically in HE stained sections.ResultsThere were significant difference at treatment groups of reperfusion 3 hours after MCAO.Infarction volume and Clinically Neurological Deficits Scale was significant reduced as control group (P<0.05). There were no significant differences at treatment groups of reperfusion 6 hours after MCAO (P>0.05). Cerebral hemorrhage wasn't increased in defibrase treatment group.ConclusionsDefibrase was effective on Clinically Neurological Deficits of rats in reperfusion 3 hours after MCAO.

Aim To ascertain whether defibrase has the protective effect against reperfusion injury after cerebral ischemia.Methods 70 renovascular hypertensive rats(RHR) were randomly divided into defibrase group, control group and sham-operated group.Reversible middle cerebral artery occlusion(MCAO) models were produced by the modified. Longa's method,and reperfusion was begun 2 hours after occlusion.Rats in the defibrase group were given defibrase 10 U?kg-1 body weight via femonal intraveneous injection, and in the control group with the same amount of saline. The brain pieces were processed by TTC and HE staining and the infarct size,brain microvessels damage and secondary bleeding were compared between the two groups. Results The volume of infarction in the defibrase group was obviously smaller than in the control group, the damage of brain microvessels was less severe, and the bleeding lesions under optical microscope were less than in the control group. Conclusion Defibrase has protective effect against reperfusion injury post cerebral ischemia.

OBJECTIVETo study the protective effect of formula of removing both phlegm and blood stasis (TYTZ) on myocardial tissues of Chinese mini-swine with coronary heart disease of phlegm-stasis cementation syndrome.

METHODTotally 36 Chinese mini-swine were randomly divided to six groups: the normal control group, the model group, the Danlou tablet group, and TYTZ groups with doses of 2.0, 1.0, 0.5 g x kg(-1), with six in each group. Except for the normal control group, all of other groups were fed with high-fat diet for 2 weeks. Interventional balloons are adopted to injure their left anterior descending artery endothelium. After the operation, they were fed with high-fat diet for 8 weeks to prepare the coronary heart disease model of phlegm-stasis cementation syndrome in Chinese mini-swine. After the operation, they were administered with drugs for 8 weeks. The SOD activity and MDA content of each group were observed at the 0th week (before the experiment), the 2nd week after the high-fat diet (before the operation or drug administration) , the 6th week after the high-fat diet (4 weeks after the drug administration) and the 10th week after the high-fat diet (8 weeks after the drug administration). Meanwhile, the myocardial enzymogram test and the HE staining pathological observation were performed at the end of the experiment. The changes in the myocardial cell ultra-structure were observed under transmission electron microscope.

RESULTCompared with the normal control group, the model group showed significant decrease in serum SOD activity and notable increase in MDA content from the 2nd week to the end of experiment (P < 0.05 and P < 0.01). In the 10th week, the CK, LDH and CK-MB levels in serum also significantly increased in the model group (P < 0.05 and P < 0.01), with obvious structural abnormality in myocardial tissue pathologic morphology and ultra-structure. Compared with the model group, TYTZ groups showed specific increase in serum SOD activity and oblivious decrease in the MDA level (P < 0.05 or P < 0.01). Meanwhile, TYTZ could significantly decrease serum CK and LDH levels in the model group (P < 0.05 or P < 0.01), attenuate the ischemia injury of myocardial tissue, and improve the ultra-structure of cardiomyocytes.

CONCLUSIONTYTZ shows an obvious protective effect on the myocardial injury in Chinese mini-swine with coronary heart disease of phlegm-stasis cementation syndrome. Its mechanism is related to the resistance against free radical oxidation injury and the inhibition of the lipid per-oxidation.
