OBJECTIVE： To investigate the effects of rosuvastatin on in-stent restenosis in middle-aged patients with acute coronary syndrome（ACS）after percutaneous coronary intervention （PCI）. METHODS： Totally 400 middle-aged ACS patients underwent PCI were selected from Xuchang Central Hospital during Mar. 2016 to Apr. 2017， and then divided into control group and observation group according to random number table， with 200 patients in each group. Both groups were given conventional drugs for secondary prevention of coronary heart disease. Control group were given Clopidogrel hydrogen sulfate tablets 75 mg， once a day+Aspirin enteric-coated tablets 100 mg， once a day+Atorvastatin calcium tablets 20 mg， once at bed time every day orally after PCI. Observation group was given Clopidogrel hydrogen sulfate tablets 75 mg， once a day+Aspirin enteric-coated tablets 100 mg， once a day+Rosuvastatin calcium tablets 10 mg， once at bed time every day orally after PCI. Both groups were treated for consecutive 12 months. The serum levels of TG， TC， LDL-C， hs-CRP and IL-35 were recorded in 2 groups before surgery， 1， 3， 6 and 12 months after surgery； in-stent minimum lumen diameter （MLD） was observed immediately after surgery and 12 months after surgery. The occurrence of in-stent restenosis， major adverse cardiovascular events （MACE） and adverse drug reaction （ADR） were recorded. RESULTS： Totally 14 patients dropped out from control group and 18 from observation group， and 368 patients completed the study. Before surgery and immediately after surgery， there was no statistical significance in the serum levels of TG， TC， LDL-C， hs-CRP IL-35 or MLD （P＞0.05）. One day after surgery， the levels of hs-CRP were increased significantly in 2 groups， compared with before surgery （P＜0.05）. One， three， six and twelve months after surgery， the serum levels of TG， TC， LDL-C and hs-CRP were decreased significantly in 2 groups， while the levels of IL-35 were increased significantly， compared with before surgery； and the serum levels of TG and TC （1 and 3 months after surgery）， LDL-C （3 and 6 months after surgery） and hs-CRP （1 month after surgery） in observation group were significantly lower than control group； the level of IL-35 in observation group （1 month after surgery） was significantly higher than control group （P＜0.05）. Twelve months after surgery， MLDs of 2 groups were decreased significantly， and observation group was significantly higher than control group （P＜0.05）. There was no statistical significance in the incidence of in-stent restenosis or the total incidence of MACE and ADR between 2 groups after surgery （P＞0.05）. CONCLUSIONS： Rosuvastatin can effectively improve the levels of blood lipid and inflammatory factor in meddle-aged patients with ACS after PCI， and its effect is better than that of atorvastatin. The drug can delay in-stent restenosis after PCI in these patients， which is better than the effect of atorvastatin. At the same time， rosuvastatin can not increase the risk of MACE and ADR with good safety.

Objective:To study the effects of resveratrol on the expressions of Caspase-3 and Bcl-2 in the retina tissue of the rats with retinal ischemia-reperfusion injury(RIRI),and to investigate the therapeutic effect of resveratrol on the RIRI and its mechanism.Methods:A total of 90 SD rats were randomly divided into sham operation group,model group and treatment group,30 rats in each group.The RIRI models were established by pressing the anterior chamber of the rats.The rats in model and treatment groups received ischemia-reperfusion for 1,6,12,24,and 48 h;the rats in treatment group were treated with micro-syringe intravitreal injection of 0.5 nmol·L-1of resveratrol 5 μL.The retinal tissue structure was observed by inverted microscope.The expression levels of Caspase-3 and Bcl-2 in retina tissue were detected by immunohistochemistry and Western blotting methods.Results:The retinal tissue edema of the rats in model group was found with vacuolar degeneration of the ganglion cells,and the arrangement of the cell layer was loose;the number of retinal ganglion cells was decreased,the boundary was blurred,and the nerve fiber layer thinned obviously.The degree of retinal tissue structure,the degree of injury and the degeneration of ganglion cells in treatment group were lighter than those in model group.The results of immunohistochemistry showed that the expressions of Caspase-3 and Bcl-2 in the retina tissue of the rats in treatment group were significantly increased compared with model group.The results of Western blotting method showed that the expression levels of Bcl-2 protein in the retina tissue of the rats in treatment group at different time points were increased compared with model group;and there were significant differences at 24 and 48 h(P<0.05);the expression levels of Caspase-3 protein in treatment group at different time points were lower than those in model group(P<0.05).Conclusion:Resveratrol can improve the retinal tissue structure of the RIRI rats,and its mechanism may be related to decreasing the expression level of Caspase-3 and increasing the expression level of Bcl-2 in the retinal tissue.

Objective To study the ketone luo acid tromethamine analgesia in patients with knee osteoarthritis joint replacement in advance of inflammatory factor and the influence of stress state. Methods Choice for knee osteoarthritis knee joint replacement patients 61 cases, were randomly divided into control group (30 caese) and the observation group (31caese), the control group only received intravenous anesthesia compound epidural block, on the basis of the observation group receied ketone luo acid tromethamine analgesia in advance, the contrast analysis of two groups of patients with preoperative and postoperative VAS score, cytokines and cortisol levels. Results The observation group of patients with postoperative pain VAS score (24 h, 48 h, 72 h) were significantly lower than control group (P<0.05);Observation group with 24h after IL - 8, TNF alpha level significantly lower than the control group (P<0.05), the observation group after 48h of IL-6, IL-8, TNF-a levels were significantly lower than control group (P<0.05).0bservation group 24h after surgery in patients with Cor significantly lower than the control level (P<0.05), after 48 h Cor and ACTH level observation group were significantly lower than the control group (P<0.05).Conclusion Ketone luo acid tromethamine analgesia in advance can obviously relieve knee osteoarthritis pain after joint replacement, and can significantly reduce inflammatory factor levels, reduce the postoperative patients with stress state.

Objective To evaluate the curative effect and safety of dibutyl phthalate on demodicidosis. Methods A single blinded and controlled study of human demodicidosis treated with dibutyl phthalate was conducted. One hundred and forty three patients with demodicidosis, including 81 acne and 62 rosacea, randomly divided into trial and control groups. The trial group was treated with dibutyl phthalate and control group with "new fumanling" cream twice a day in the early morning and evening respectively for six weeks consecutively. Results The rates of excellent, good, and fair efficacy and total effective rate in the trial group with acne were 53^7%, 41^5%, 4^9% and 100% respectively, with a significant difference to the control group (P0^05). No complaint of side effects in the trial group was recorded. Conclusion Dibutyl phthalate is highly effective to demodicidosis without prominent adverse reactions.
