OBJECTIVE:To prepare rapid-disintegrating oral tablets of indometacin and establish a method for its quality control.METHODS:The formula of the oral tablets was optimized by orthogonal test with the formula quality of CMS-Na(A),L-HPC(B),MCC(C),manniton(D) as factors,and the disintegrating time as index.The content of indometacin was determined by ultraviolet spectrophotometry.RESULTS:The optimal formula of the tablets was the following,A∶B∶C∶D=5∶5∶50∶5.The preparation was white in color and its quality was up to the related standard specified in Chinese Pharmacopeia (2005 edition) in identification.The linear range of indometacin was 2.08～41.6 ?g?mL-1 (r=0.999 9).The average recovery was 99.3%.The intra-day RSD=0.53% and inter-day RSD=0.74%.CONCLUSION:The preparation is simple and feasible in preparation process,and controllable in quality.

OBJECTIVE:To investigate the inhibitory effect of ligustrazine on the formation of macrophage-derived foam cells and its possible mechanism. METHODS:Human acute mononuclear cells (THP-1) were incubated with 160 nmol/L phorbol ester (PMA) for 24 h to differentiate into macrophages;and the macrophages were incubated with oxidized low-density lipoprotein (ox-LDL)culture solution containing 80 mg/L for 24 h to differentiate into macrophage-derived foam cells. And then the cells were randomly divided into blank control group(ox-LDL),model(AngⅡ)group,positive control(valsartan)group,and ligustrazine low,medium and high concentration groups(the mass concentration were 0.025,0.05 and 0.1 g/L). After all cells were respective-ly incubated with 80 mg/L ox-LDL culture solution for 48 h,oil red O staining was adopted to observe the transformation rate of foam cells,enzyme chemical method was used to determine the content of cholesterol,and real-time quantitative polymerase chain (RT-PCR)and Western blot were conducted to detect expression levels of Acyl-coenzyme A cholesterol acyltransferase-1(ACAT-1) mRNA and its protein. RESULTS:Compared with blank control group,the transformation rate of foam cells and content of choles-terol in model group were increased,and the expression levels of ACAT-1 mRNA and its protein were obviously strengthened,with significant differences(P<0.01 or P<0.05). Compared with model group,the transformation rate of foam cells and content of cho-lesterol in positive control group(valsartan)and ligustrazine low,medium and high concentration groups were decreased,and the expression levels of ACAT-1 mRNA and its protein were obviously weakened,with significant differences (P<0.01 or P<0.05). CONCLUSIONS:Ligustrazine can inhibit the macrophages differentiating into foam cells,by a mechanism that may be related to inhibiting expression of ACAT-1,and reducing content of cholesterol to reduce formation of foam cells.

Objective To explore the clinical value of multi-slice CT in distinguishing between benign parotid tumors and malignant parotid tumors. Methods CT scanning images of 72 parotid tumor patients were analyzed. The location, shape, density, edge, cystic necrosis and degree of enhancement of the tumors were analyzed, de-gree of cervical lymph node swelling were analyzed, and all the analysis results were compared to pathological re-sults. Results 80 lesions were diagnosed in tumors, among which 59(73. 8%) lesions were benign tumors and 21 (26. 2%) lesions were malignant tumors. The CT images of benign tumors showed that 42(71. 2%) of them were located in the superficial lobe and with regular shape and uniform density;62.7% of them had clear edge;57 . 6%of them showed mild or moderate enhancement. 2 cases of benign tumors presented cervical lymph node swelling, which were proved to be pathological inflammatory mass after operation. Whereas in the CT images of malignant tumors 12( 57. 1%) of them were located in the deep lobe or in both of the superficial lobe and the deep lobe. 15 (71. 4%) of them had irregular shape and uneven density. 81% of them had unclear edge. 71. 4% of malignant tumors were significantly enhanced. 9 cases of malignant tumor were with cervical lymph node metastasis. There was statistical difference between the shape, edge, density, cystic necrosis, degree of enhancement and cervical lymph node metastasis of the two groups of tumors(P<0.05), while the location and the degree of enhancement of the two groups of tumors showed no statistical difference ( P>0.05 ) . Conclusion Most of benign and malignant parotid tumors can be correctly diagnosed by analyzing multi-slice CT images.

Adiponectin is a kind of adipocyte-specific protein which is only inversely related with obesity by now. It is involved in enhancing insulin sensitivity,anti-atherogenic and antiinflammatory activities.Recent studies have reported that adiponectin is closely correlated with the genesis and development of a variety of obesity related malignant tumors,especially postmenopausal breast cancer.Obesity is an independent risk factor for the development of breast cancer.Recently researches about the correlation between adiponectin and breast cancer relations and the action mechanisms,signaling pathways have made a progress.

Objective To probe into the methods of postoperative nursing care for the patient undergoing domino liver transplantation.Methods The key of postoperative care included:monitoring of vital signs,the condition of cruor and the state of drainage rigorously; keeping the balance of intake and output; taking the immunosuppressive drugs correctly; proper diet; prevention of complication;giving psychological nursing.Results The patients passed the perioperative period successfully and were all cured.Conclusions To aim at the characteristic of this operation,implement holistic nursing care,is an important link to assure the patients of domino liver transplantation to recover smoothly after the operation.

Objective To investigate the incidence and the risk factors of the vascular disease in lower limbs of patients with type 2 diabetes(T2DM).Methods To retrospectively analyze 318 cases with T2DM patients.All the patients were checked on both lower limbs by color ultrasonic Doppler.The differences of ordinary and biochemical indicators between PVD group and non-PVD group were compared.Results There were 67.2％ (205/318) patients who had vascular disease in lower limbs with type 2 diabetes.Age,course of disease,HbAlC,TC,TG,SBP,DBP and BMI in PVD group were significantly higher than those in non-PVD group( P ＜ 0.01 ).Conclusion There was higher incidence of the vascular disease in lower limbs of patients with type 2 diabetes.And the independent risk factors were hypertension,hyperglycemia,hyperlipemia.It could help to prevent the development of lower limb blood vessel pathological changes in DM patients by controlling the levels of blood pressure,lipid and blood sugar strictly.

Objective To systematically review the effects of air or liquid in a loss of resistance technique for identification of the epidural space. Methods We searched the Cochrane Library, PubMed, EMBASE, Chinese Biomedical Database (CBM), CNKI, VIP and ChinaInfo for studies on the effects of air versus liquid in a loss of resistance technique for identification of the epidural space. The quality of the studies was evaluated by the method recommended by Cochrane Collaboration. Meta-analysis was conducted using the Cochrane Collaboration's RevMan 5.0.1 software. Results Seven prospective randomized controlled trials involving 5183 patients were included in our meta-analysis. The patients were randomly allocated into 2 groups according to the technique by which the epidural space was identified: loss of resistance with air group (group air, n = 2534) and loss of resistance with liquid group (group lidocaine, n = 2649). The results showed that the incidences of difficult catheterization, intravascular catheter insertion, incomplete block and post-operative headache were significantly lower in group liquid than in group air (P ＜ 0.05). There were no significant differences in the incidences of transient abnormal sense and accidental dural puncture between group liquid and air. Conclusion Loss of resistance with liquid can identify the epidural space more correctly than with air, with fewer complications and better analgesic efficacy.
