AIM To investigate the changes of biochemical index of osteoporosis in rats induced by given total flavonoids of herba epimedii (HEF) . METHODS The rat osteoporosis was induced by given retinoic acid intragastrically, the biochemical index in serum (T, E 2, ALP, PTH, BGP, Osteocalcin ) and in urine (Ca, P, DPD and Cr) were determined after the rats were given HEF by low, middle and high dosages respectively, and were compared with the model group. The normal control and the positive control. RESULTS The E 2, T and BGP level in all three dosage groups were obviously higher than that of the model group. The Ca/Cr, DPD and PTH level were obviously lower than the model group. The content of Ca and P and the bone density in femur were similar with the normal control, and there was significant difference compared with the model group. CONCLUSION HEF prevents the rats treated by retinoic acid from becoming osteoporosis. The changes of biochemical index were consistent with the variation of bone density, indicating the great significance of biochemical index in diagnosis and treatment of osteoporosis.

Objective To explore the influence of the combination therapy of probucol with atorvastatin on levels of serum high sensitivity C-reactive protein (hs-CRP), oxidized low-density lipoproteins (ox-LDL), and marix metallopro? teinase-9 (MMP-9) and resolution of carotid plaque in patients with acute cerebral infarction (ACI). Methods One hun? dred-six patients with acute cerebral infarction who had carotid artery color Doppler ultrasound-confirmed atherosclerot? ic plaques , were included in the present study. The patients were randomly divided into two groups: conventional treat? ment group ( 40 cases) which received atorvastatin (20mg/d) and co-treatment group (40 cases) which received Atorvas? tatin (20mg/d) and Probucol (500mg/d). Levels of hs-CRP, ox-LDL and MMP-9 were detected in all patients before treat? ment and 1, 6 and 12 months after drug therapy. The Intima-media thickness, area and numbers of carotid plaques were evaluated by using Doppler ultrasonography during a 12 months follow-up period. Results ① Serum hs-CRP and MMP-9 levels were significantly decreased at 1, 6 and 12 months after treatment, (conventional treatment group:t =14.662, 23.586, 28.179 and co-treatment group:t =47.023, 50.239, 50.774,P <0.01). The ox-LDL levels was obviously de? creased in the combined treatment group (t =4.592, 5.011, 5.892,P <0.01) but not in conventional treatment group (P > 0.05) at 1, 6 and 12 months after treatment. Serum hs-CRP, ox-LDL and MMP-9 levels were significantly lower in com? bined treatment group than in the conventional treatment group at all time points after treatment (t =7.655, 5.271, 2.492, t =4.927, 3.772, 4.673 andt =16.862, 4.251, 2.045.P <0.01 orP <0.05). ②There were not statistically differences in the IMT, plaque area and plaque numbers between these two groups before treatment (P >0.05). The IMT, plaque area and plaque numbers were significantly smaller in combined treatment group than in conventional treatment group (t =6.117, 3.290, 2.158,P <0.05). Conclusions The combination therapy of probucol with atorvastatin can greatly reduce levels of serunl hs-CRP,ox-LDL and MMP-9, indicating that the combination therapy has a strong anti-oxidant function, thereby reversing and stabilizing the atherosclerosis plaque.

Objective To investigate the relationship between serum cholesterol levels and immunoglobin types and clinical stages in the patients with multiple myeloma (MM). Methods We retrospectively analyzed the blood lipid levels in 65 patients with MM at diagnosis, including total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), apolipoprotein Al (apo-Al) and apolipoprotein B (apo-B), and explored relationship between lipid parameters and immunoglobulin types or clinical stages in patients with MM. Thirty healthy persons were served as controls. Results Of the 65 MM patients, 53.85% were IgG type, 63.1 % were at stage Ⅲ. The levels of TC, HDL-C, LDL-C, apo Al and apo B in the patients with MM were significantly lower than that in the controls (P <0.05), and TG in MM patients was no difference with that in the controls (P >0.05). Except one case of IgD type, the levels of TC, HDL-C, LDL-C, apo Al and apo B in Ig G and Ig A types of patients were significantly lower than that in the light chain type among other 64 cases (P <0.05), and TG levels in different immunoglobulin types was found no statistical differences. The levels of TC, HDL-C, LDL-C and apo A1 in the patients with stage Ⅲ were lower than that of stage I and controls (P <0.05), furthermore, the level of LDL in stage Ⅱwas lower than that in stage Ⅰ. Conclusion Hypocholesterolemia are seen in the patients with MM and serum cholesterol levels are related to MM staging.

Objective To investigate the effect of simvastatin (SV) in combination with cytosine arabinoside (ARA-C) on the proliferation and apoptosis of K562 cells. Methods Human K562 cells were incubated with SV and cytosine arabinoside alone or in combination and K562 cells without any treatment were taken as normal control. Cells in different groups were collected at 24, 48 and 72 h after incubation for further detections. Morphological changes by Wright stain were performed. MTT method was used to assay the growth inhibition rate and cytoflowmetry was used to detect the early stage apoptosis ratio and cell necrosis ratio. Results Compared with Ara-C group and SV group, cells in the group treated with SV combined with Ara-C showed obvious karyopyknosis,apoptosis bodies formation and significant cell growth inhibition, which were positively correlated with culture time. Combination of 15 μmol/L SV and Ara-C showed the most significant cell growth inhibition with a inhibition rate of (72±1) % at 72 h of culture, as was significantly higher than that of 15 μmol/L SV group (45±2) % and 20 μmol/L Ara-C group (44±0) % (P <0.01),furthermore, combination of 15 μmol/L simvastatin and Ara-C showed synergistic inhibition with Q value of 1.24 and 1.19 at 24 h and 48 h in each. The apoptosis rates at early stage (AnnexinV) detected by flow cytometry in 20 μmol/L, 15 μmol/L and 10 μmol/L SV treated K562 cells were significantly higher than that in normal K562 cells (P <0.01), as were positively correlated with culture time and SV dose (P <0.05). There were no significant difference of early apoptosis rate between the 20 μmol/L SV and 15 μmol/L SV groups (P >0.05), yet the very two were both higher than that of 10 μmol/L SV group (P <0.05). There were no statistic differences of late apoptosis rate (PI) amongdifferent treated groups (P >0.05). Conclusion SV inhibited K562 cell proliferation and induced cell apoptosis in vitro, and combination of SV and Ara-C exhibited obvious synergistic inhibition and apoptosis, which may increase the sensitivity of K562 cell to chemotherapy. SV at 15 μmol/L may be the best concentration for K562 cells in vitro.

Purpose:
This study aimed to investigate the changes in microRNA-130a (miR-130a) and its correlation with cardiotoxicity during epirubicin/cyclophosphamide followed by docetaxel plus trastuzumab (EC-D+T) adjuvant chemotherapy in human epidermal growth factor receptor-2-positive (HER2+) breast cancer patients.
Methods:
A total of 72 HER2+ breast cancer patients who underwent resection and were scheduled to receive EC-D+T adjuvant therapy were consecutively enrolled. The expression of miR-130a and cardiotoxicity (defined as any of the following situations: 1) absolute decline of left ventricular ejection fraction (LVEF) ≥ 10% and LVEF < 53%; 2) heart failure; 3) acute coronary artery syndromes; and 4) fatal arrhythmia) were assessed every 3 months throughout the 15-month EC-D+T treatment.
Results:
The accumulating cardiotoxicity rate was 12 (16.7%), of which the incidence of heart failure, acute coronary syndrome, life-threatening arrhythmias, ΔLVEF ≥ 10%, and LVEF < 53% was 0 (0.0%), 1 (1.4%), 0 (0.0%), and 12 (16.7%), respectively. Baseline miR-130a expression was negatively correlated with LVEF (%) and positively correlated with cardiac troponin I. The expression of miR-130a gradually increased in both cardiotoxicity and noncardiotoxicity patients during EC-D+T treatment, while the increment of miR-130a was more obvious in cardiotoxicity patients compared with non-cardiotoxicity patients. Further logistic regression and receiver operating characteristic curve analysis indicated that miR-130a was an independent predictive factor for increased cardiotoxicity risk.
Conclusion
MiR-130a increases constantly and predicts high cardiotoxicity risk during ECD+T adjuvant chemotherapy in HER2+ breast cancer patients.
