Objective To investigate the effect of atorvastatin on the curative effect and cardiovascular events in patients with unstable angina pectoris.Methods128 patients with UAP were enrolled in Jinhua Central Hospital from August 2014 to August 2016, and 128 patients with UAP were randomly divided into observation group and control group.All the patients were given low salt and low fat diet.Two groups of patients were anti-platelet aggregation, blood pressure, lipid-lowering and other conventional treatment, observation group on the basis of simultaneous atorvastatin calcium 40mg/d, oral, once every month.The levels of TC, TG and LDL-C, HDL-C and the incidence of cardiovascular events were compared between the two groups before and after treatment.ResultsThere was no case of cardiac death in the observation group and the control group.The incidence of cardiovascular events in the observation group was 9.38%, which was significantly different from that in the control group (P<0.05).The levels of TC, TC and LDL-C in the observation group were significantly higher than those before treatment and control group, respectively.The clinical effect of the observation group was significantly better than that of the control group, the difference was significant (P<0.05).ConclusionAtorvastatin can significantly improve the efficacy of unstable angina treatment, and reduce blood lipid levels, reducing the incidence of cardiovascular events, improve the prognosis.

Objective To investigate the relationship between the expression of Fas or FasL and the apoptosis of peripheral blood T and B lymphocytes in systemic lupus erythematosus (SLE) patients. Methods The expression rates of Fas and FasL and apoptosis rates of peripheral blood T and B lymphocytes were detected by flow cytometry (FCM) in 30 active SLE patients and 30 inactive SLE patients and 30 healthy controls. Results There were significant difference in the expression rates of Fas of T and B lymphocytes among three groups (P0.05). In addition, the activity of SLE had no correlation with the expression rates of Fas or FasL on T or B lymphocytes but has positive correlation with the apoptosis rates of T or B lymphocytes. And no correlation was found between the expression rate of Fas or FasL and the apoptosis rate of neither T nor B lymphocytes. Conclusion The apoptosis of peripheral blood lymphocytes is influenced by many factors in SLE patients, but is abnormally increased at last, especially in active SLE. It is inferred that the increase of apoptosis rate of peripheral blood lymphocytes plays an important role in the pathogenesis of SLE.

BACKGROUND: Calcium phosphate cement (CPC) can strengthen the immediate and early fixation of screws by improving the quality of bone and the surface of screws. OBJECTIVE: To evaluate the biomechanical efficacy of CPC in augmentation of anterior cervical unicortical screw fixation. DESIGN: A study of controlled observation. SETTING: Department of Orthopaedics of First Xiangya Hospital of Xiangya Medical College of Central South University. MATERIALS: Experiments were performed at the Room of Electromechanical Tensile Property of College of Material Science and Engineering of Central South University from September 2003 to January 2004. Anterior cervical unicortical screw (pure titanium) was produced by Zhangjiagang Xinda Medical Equipment Co., Ltd. Injectable calcium phosphate cement was produced by Shanghai Ruibang Biomaterial Co., Ltd. Axial pull-out sleeve was produced by Machine Manufacture Center of Central South University. METHODS: ①Sixteen cervical vertebrae (C3-6) of four fresh young man cadavers with fine results in bone mineral density (BMD) test and sixteen cervical vertebrae (C3-6) of 4 fresh old man cadavers with poor results in BMD test were selected. Specimens were provided by Department of Anatomy of Xiangya Medical College of Central South University. Mortal remains of the deceased were donated according to the will of the dead. Informed consents were obtained from their family members. Twelve vertebrae were selected in each group for three tests. Six vertebrae were selected in pull-out test, and six vertebrae in cyclic bending test and shearing test. Screw holes, which were 8 mm apart from the midline and 5°inclined centrally, were made on both sides in the front part of the vertebra. Cortical bone was not penetrated. ②A screw was randomly inserted into one side hole, which was considered to be a control group. Pull-out test was performed on material testing machine at 5 mm/min. The screw hole was filled with CPC (0.10-0.15 mL) to repair the screw hole, and then the screw was implanted, which was considered to be a restoration group. The screw hole was injected with CPC, and then the screw was implanted, which was considered to be a augmentation group. 24 hours later, pull-out test was conducted again at 37 ℃. ③The screw was randomly implanted into one side hole (as a control group). The screw hole was injected with CPC, and then screw was implanted (as an augmentation group). Both groups received cyclic bending test and shearing test. MAIN OUTCOME MEASURES: ①The maximal axial pull-out strength of screws, ②displacement of screws after cycle bending test, ③the maximal shear strength after cycle bending test. RESULTS: ①The axial pull-out test: In normal vertebrae, axial pull-out strength was (313±64)N, (376±88)N and (446±121)N in the control group, the restoration group and the augmentation group respectively. In osteoporotic vertebrae, axial pull-out strength was (106±47)N, (154±67) N and (191±80)N in the control group, the restoration group and the augmentation group respectively. The axial pull-out strength in the restoration group and augmentation group was significantly bigger than in the control group (P < 0.05). ②The cyclic bending test: The displacement of the unicortical screw in the augmentation group was much smaller than in the control group (P < 0.05). ③ In normal vertebrae, the maximal shear strength was (301±79)N and (395±105)N in the control group and the augmentation group respectively. In the osteoporotic vertebrae, the maximal shear strength was (87±39)N and (149±63)N in the control group and the augmentation group respectively. The maximal shear strength was significantly bigger in the augmentation group than in the control group (P < 0.05).CONCLUSION:CPC can enhance the axial pull-out strength and shearing ability of the screw. The augmentation is more evident in osteoporosis patients.
