The formation of macrophage-derived foam cells is a typical feature of atherosclerosis (AS). Reverse cholesterol efflux (RCT) is one of important factors for the formation of macrophage foam cells. In this study, macrophage form cells were induced by oxidized low density lipoprotein (ox-LDL) and then treated with different concentrations of ferulic acid, so as to observe the effect of ferulic acid on the intracellular lipid metabolism in the ox-LDL-induced macrophage foam cell formation, the cholesterol efflux and the mRNA expression and protein levels of ATP binding cassette transporter A1 (ABCA1) and ATP binding cassette transporter G1 (ABCG1) that mediate cholesterol efflux, and discuss the potential mechanism of ferulic acid in resisting AS. According to the findings, compared with the control group, the ox-LDL-treated group showed significant increase in intracellular lipid content, especially for the cholesterol content; whereas the intracellular lipid accumulation markedly decreased, after the treatment with ferulic acid. The data also demonstrated that the mRNA and protein expressions of ABCA1 and ABCG1 significantly increased after macrophage foam cells were treated with different concentrations of ferulic acid. In summary, ferulic acid may show the anti-atherosclerosis effect by increasing the surface ABCA1 and ABCG1 expressions of macrophage form cells and promoting cholesterol efflux.

A questionnaire survey on awareness of child health management was conducted in 238 family members ( 236 were parents) of children aged 0 - 36 months; among whom 92 of children aged 0 to 6 months,85 of children aged 7 to 12 months,33 of children aged 13 to 18 months,16 of children aged 19 to 24 months and 12 of children aged 24 to 36 months.52.1％ of the surveyees had college education level.The awareness about medical examination in last half year in female subjects was higher than males ( P ＜ 0.05).There were no differences in other health management knowledge.The results showed that the average times of medical examination was 2.8 ± 1.9 in last half year; the age for supplement of meat in food was 7.4 ± 2.4 mouths; supplement of meat,animal liver and eggs was more than 7 time a week.The subjects with college education or above paid more attention to the children's growth,risk for rickets and anemia than other peoples.Pure breast feeding accounted for only 37.0％ (88/238).The study indicates that strengthening the knowledge and awareness is necessary to improve the children health management.

The preparation method, serum stability, efficiency of cellular uptake and apoptosis induction of the cell penetrating peptide TAT and cleavable PEG co-modified liposomes loaded with paclitaxel (C-TAT-Lipo) were investigated. The best preparation procedure was performed by orthogonal test based on single factor screening method. First, the paclitaxel (PTX)-loaded liposomes were prepared by filming-rehydration method, evaluated with entrapment efficiency and polydispersity index. The morphology of C-TAT-Lipo was characterized by transmission electron microscopy. Turbidity variations were monitored in the presence of fetal bovine serum (FBS) to evaluate the serum stability of the liposomes developed here. Next, the efficiency of cellular uptake of different Rho-PE-labeled liposomes on B16F1 cells in vitro was evaluated by confocal laser scanning microscopy (CLSM) and flow cytometry. The quantitative analysis of apoptosis induced by different PTX-loaded liposomes was performed by Annexin V-FITC/PI double staining. The optimal formulation was as follows: Chol : lipid: 1 : 8 (molar ratio); drug : lipid: 1 : 40 (mass ratio); lipid concentration: 3 mmol x L(-1); temperature of hydration: 25 degrees C. The mean size and polydispersity index of C-TAT-Lipo were about (97.97 +/- 3.68) nm and 0.196 +/- 0.037, the zeta potential was (-0.89 +/- 0.45) mV, the entrapment efficiency of paclitaxel was (90.16 +/- 1.53)%. The particle sizes did not exhibit significant variations in 50% FBS over 24 h at 37 degrees C. The efficiency of cellular uptake of the C-TAT-Lipo increased 1.40 fold following the cleavage of PEG. Apoptosis analysis showed 59.3% increase of the apoptosis and necrosis profile of C-TAT-Lipo after the detachment of PEG shells, which was markedly higher than that of N-TAT-LP with or without glutathione and SL, respectively. The results indicate that the C-TAT-Lipo is successfully prepared by filming-rehydration method and shows significant antitumor activities.

Objective To explore the method for establish the temporal lobe epilepsy model in SD rats with stereotactic technique and to study the characteristic of electroencephalography (EEG) after epileptic seizure. Methods Kainic acid was injected into right hippocampus via stereotactic technique in 20 rats, and the behavior of rat was recorded by a video camera. The electrical activity changes of brain were recorded by EEG in bilateral hippocampus, amygdala and frontal lobe. Results According to Racine's scale, 6 rats were typeⅤ,10 rats were type Ⅳ,3 rats were type Ⅲ,1 rat was type Ⅱ. The spike wave was originated from hippocampus and spread to amygdala and frontal lobe. Pathologic changes showed that prolonged seizures induced pyramidal cell loss and death in hippocampus. Conclusions The method to establish kainic acid induced temporal lobe epilepsy model with stereotactic technique was credible, economical and useful. The spike wave originated from hippocampus was the basic feature of EEG of temporal lobe epilepsy model in rats.

Objective To investigate the expression pattern of hypoxia inducible factor-1?(HIF-1?) in fetal vertebra development of the mouse. Methods The development of mouse fetal vertebra was observed dynamically,and the expression of HIF-1? mRNA at various stages was also detected by reverse transcription-polymerase chain reaction. Results The cartilaginous spine column began to form at E13.5.The primary ossification center was observed at E15.5,then the osteogenesis expanded and extended to both sides.HIF-1? mRNA began to express at E13.5,and more significantly at E14.5(P

Objective To explore the safety and effectiveness of transurethral resection of the prostate (TURP) for large benign prostatic hyperplasia.Methods A total of 56 cases of patients with large benign prostatic hyperplasia were analyzed retrospectively.Results The weight of prostate tissue resected with TURP was 60.2 g (48-122 g).The resection rate was 60％,operation time 113.4 min (70-180 min).The lower urinary tract symptoms (LUTS) after TURP was improved significantly.The international prostate symptom scores (IPSS) of 38 cases were decreased from (25.6±1.5) before operation to (6.0± 2.0) after operation.The maximum urine flow rate were increased from (5.0±1.9) ml/s to (18.0±4.5) ml/s.The mean residual urine volume of 22 cases were reduced from 95 ml (40-250 ml) to 10 ml (0-60 ml).Conclusions Skilled TURP technology for large benign prostatic hyperplasia is a safe treatment with good effect and low complications rates.

Objective To evaluate the efficacy of gabapentin for prevention of post-thoracotomy pain syndrome (PTPS).Methods Sixty-nine ASA physical status Ⅰ or Ⅱ patients of both sexes,aged 46-69 yr,weighing 47-78 kg,scheduled for elective resection for lung cancer under general anesthesia combined with epidural block,were randomly divided into 2 groups using a random number table:group A (n =36) and group B (n =33).In group A,gabapentin 300 mg was given orally at 2 h before operation and gabapentin 100 mg was given orally three times a day from 1st day after operation until 10th day after operation.Group B received placebo instead of gabapentin.Epidural blockade with ropivacaine and sufentanil was performed before induction of anesthesia and the level of block was controlled at T4-10.Patient-controlled epidural analgesia (PCEA) was performed within 3 days after operation and VAS scores were maintained ≤ 3.The development of pain (numeric rating scale score ＞ 4) within 6 months after operation and the duration were recorded.The consumption of propofol and remifentanil during operation and the number of attempts for PCEA after operation were recorded.The adverse reactions such as postoperative drowsiness,dizziness,fatigue were also recorded.Results Compared with B group,the incidence of pain within 6 months after operation was significantly decreased,the duration of pain was shortened (P ＜ 0.05),and no significant changes were found in the consumption of propofol and remifentanil during operation and the number of attempts for PCEA after operation in A group (P ＞ 0.05).No adverse reactions developed in group B.Mild dizziness and fatigue occurred in 2 patients in group A.Conclusion Gabapentin (continuous application at 2 h before operation and 10 days after operation) can reduce the development of PTPS in patients with no obvious adverse reactions.
