Objective:To investigate the effects of different doses of rosuvastatin on lipid levels in elderly patients with CHD complicated with hyperlipidemia.Methods:120 elderly patients with coronary heart disease admitted in our hospital were retrospectively chosen.By lipid examination,they were all hyperlipidemia.According to the dose of rosuvastatin,they were divided into three groups,and 40 cases in each group.They were given 5 mg,10 mg and 20 mg treatment,respectively.After 2 months,the changes of blood lipid level and the clinical effective rate were compared before and after the treatment.Results:①The blood lipid levels HDL-C [(1.17 ± 0.62) mmol / L] was significantly higher than the other two groups.LDL-C [(3.67 ± 0.83) mmol / L],TC [(4.36 ± 0.96) mmol / L] and TG [(1.68 ± 0.94) mmol / L] were significantly lower than those of the other two groups (P ＜0.05).②The effective rate of treatment in the 20mg group (97.5％) was significantly higher than that in the 5mg group (87.5％) and the 10mg group(85.0％).Conclusions:Rosuvastatin can treat coronary heart disease complicated with hyperlipidemia in elderly patients.The dosage of 20 mg can improve the blood lipid level of the patients,is an effective and convenient method,and with high therapeutic efficiency.

BACKGROUND:Cervical Open-door laminoplasty with unilateral mass screw fixation and laminectomy with bilateral mass screw fixation are both procedures that treat cervical spondylotic myelopathy by expanding the space available for the spinal cord. Effectiveness and safety of two operative methods remain unclear. OBJECTIVE:To investigate the biocompatibility of implant and host between open-door laminoplasty with unilateral mass screw fixation and laminectomy with bilateral mass screw fixation to treat multi-segment cervical spondylotic myelopathy. METHODS: Data of 117 patients with multi-segment cervical spondylotic myelopathy (≥ 3 segments) were retrospectively analyzed. Sixty-five cases underwent open-door laminoplasty with unilateral mass screw fixation (laminoplasty group). Fifty-two cases underwent laminectomy with bilateral mass screw fixation (laminectomy group). Clinical outcomes were evaluated by the Japanese Orthopaedic Association scoring system and by recovery rate. Cervical curvature index and cervical range of motion were assessed by X-ray films in both groups. RESULTS AND CONCLUSION:The average folow-up time was 28 months (range 12-59 months) in both groups. No C5 nerve root palsy occurred in the two groups. Japanese Orthopaedic Association scores were greater during final folow-up than pre-fixation in both groups (P < 0.01). No significant difference in Japanese Orthopaedic Association score, recovery rate, and final folow-up cervical curvature index was detected in both groups (P > 0.05). Cervical range of motion was lower during final folow-up than pre-fixation in both groups (P < 0.01). Results confirmed that open-door laminoplasty with unilateral mass screw fixation and laminectomy with bilateral mass screw fixation have similar effectiveness in the improvement of neurological function, relieving pain and reducing complications, but wil greatly reduce the cervical range of motion.

Twelve patients with advanced gastric cancer were recruited to the study. The dose of S-1 for each patient was determined according to his/her body surface area (BSA). The dose for single administration was 60 mg every subject. The dose for multiple administration for one subject was as follows: 100 mg x d(-1) or 120 mg x d(-1), 28-days consecutive oral administration. The pharmacokinetic parameters of tegafur, 5-fluorouracil, gimeracil, potassium oxonate and uracil after single oral administration were as follows: (2,207 +/- 545), (220.0 +/- 68.2), (374.9 +/- 103.0), (110.5 +/- 100.8) and (831.1 +/- 199.9) ng x mL(-1) for Cmax; (11.8 +/- 3.8), (4.4 +/- 3.3), (7.8 +/- 5.1), (3.1 +/- 0.9) and (8.8 +/- 4.1) h for t1/2, respectively. After six days oral administration, the average steady state plasma concentrations (Cav) of tegafur, 5-fluorouracil, gimeracil, potassium oxonate and uracil were (2,425 +/- 1,172), (73.88 +/- 18.88), (162.6 +/- 70.8), (36.89 +/- 29.35) and (435.3 +/- 141.0) ng x mL(-1), respectively, and the degree of fluctuation (DF) were (1.0 +/- 0.2), (2.5 +/- 0.4), (3.1 +/- 0.8), (2.4 +/- 0.8) and (1.5 +/- 0.3), respectively. The cumulative urine excretion percentage of tegafur, 5-fluorouracil, gimeracil and potassium oxonate in urine within 48 h were (4.2 +/- 2.8) %, (4.7 +/- 1.6) %, (18.5 +/- 6.0) % and (1.7 +/- 1.2) %, repectively, after single oral administration of S-1. The results exhibited that tegafur had some drug accumulation observed, and gimeracil, potassium oxonate, 5-fluorouracil and uracil had no drug accumulation observed.
