Objective To investigate the expression level of monocytes ATP-binding cassette transporter A1(ABCA1) stimulated by oxidized low-density lipoprotein (ox-LDL) in patients with coronary heart disease (CHD) for exploring the mechanism of ABCA1 in the pathogenesis of atherosclerosis (AS). Methods Human monocytes of patients in CHD group (n=42) and normal control group (n=40) were isolated by density gradient centrifugation with separating medium (1.077). ABCA1 was labeled by immune reaction PE fluorescence, then the expression of ABCA1 before and after being incubated with the ox-LDL (30mg/L) for 24 hours was investigated by flow cytometer, and the changes in ABCA1 expression were observed. The differences between the two groups and the correlation between ABCA1 expression and blood lipids were analyzed. Results The high-density lipoprotein cholesterol (HDL-C) and apolipoprotein A1 (apoA1) levels in CHD group (1.15?1.40 and 1.19?0.17, respectively) were significantly lower than that in control group (1.36?0.40 and 1.34?0.22, respectively, P0.05). Conclusions ABCA1 expression in the patients with CHD may be inhibited by high concentration of ox-LDL. The lowered expression of ABCA1 and the abnormal lipids spectrum may decrease the reverse cholesterol transport (RCT), and contribute to the development of AS and CHD.

To summarize the etiological factor and to assess the therapeutic effect for neovascular glaucoma(NVG).Methods A retrospective study of 28 cases (29 eyes) with NVG was performed. The mean age, proportion of sex and primary ocular disease, incidence of symptom, sign and postoperative complication were analyzed. Results 78 6% of the patients were over 40 years old. 62% of the patients were secondary to the ocular ischemic disease such as central retina vein occlusion and proliferative diabetic retinopathy. The clinical characters included intraocular pressure (IOP) increasing, pain, mixed conjunctival congestion and rubeosis iridis. The mean IOP reduction was 19.5 mmHg in 29 eyes after antiglaucomatous drags treatment and 19.13mmHg in 23 eyes after Hunan aqueous humor drainage (HAD) implantation. The common postoperative complications were flat anterior chamber and choroidal detachment. The success rate of HAD implantation was 87%.Conclusions NVG was commonly secondary to ocular ischemic disease. Although prevention was the principal, reducing IOP and ameliorating ischemic situation were as the same important.

Transcatheter arterial chemoembolization (TACE) is the first choice of patients with hepatocellular carcinoma (HCC) missed opportunity of exairesis.Angiogenesis is one of the key factors that affect prospective efficacy.Counter-measures against angiogenesis mainly contain complete embolization of tumor blood supply and integration with angiogenesis inhibitors.The angiogenesis after TACE and the corresponding countermeasures were reviewed in this article.

Microwave ablation(MWA) is a significant progress in tumor non-surgical treatment in the 1990s.It is characterized by high thermal efficiency,fast heating rate,high uniform temperature field,complete necrosis of coagulation area and small influencing factors.The local treatment of the tumor shows a great advantage.In recent years,with the maturity of MWA technology,it has been widely used in the treatment of liver tumors(hapatic tumor,HT),has achieved good clinical efficacy.The aim of this study is to review the progress of treatment of HT in MWA to improve its therapeutic efficiency.

Hematoma growth is an independent risk factor for the prognosis of htracerebral hemorrhage.It is very common in the acute stage of intracerebral hemorrhage.There are many uncertainties about the definition,mechanisms,and influential factors of hematoma growth,and the effective therapy is lacking,therefore,early prevention and identification are critical.

OBJECTIVE:To investigate the characteristics of serious ADR in psychiatric hospital,and to provide reference for effective and safe use of drugs in the clinic. METHODS:114 cases of serious ADR in our hospital from 2004 to 2015 were ana-lyzed retrospectively in terms of general information,primary disease,route of administration,dosage form,drug types,organs or systems involved in ADR and clinical manifestations,top 5 ADR-inducing drugs and main clinical manifestations,etc. RESULTS:Of 114 serious ADR cases,the number of female was more than that of male(71/43). Patients aged 21-30 years old took up the greatest proprotion(35 cases,30.70%). The main involved primary disease was schizophrenia(54 cases,47.37%). Oral adminis-tration-induced ADR was most common(103 cases,90.35%). The main involved drugs were antipsychotics,occupying the great-est proportion(75 cases,65.79%). Digestive system involved was the most common(53 cases,42.74%), Olanzapine tablets had the highest incidence of serious ADR (23 cases,18.55%),the main clinical manifestation were both abnormal liver function. There were 8 cases of new serious ADR (7.02%). Most of the ADR can be cured after drug withdrawal or countermeasures,no death case was found. CONCLUSIONS:Psychiatric drugs can induce serious ADR as treat psychiatric disease,among which the in-cidence of ADR induced by Olanzapine tablets is the highest and mainly manifestes digestive system symptoms. It is suggested to strengthen serious ADR monitoring to promote the safe use of drugs.

Objective To study the stability of alkaline and degraded products of curcumin by high performance liquid chromatography(HPLC) and HPLC-mass spectrometry (MS) for the optimization of alkaline-dissolved process parameters of the Jianghuang Qingzhi Tablets and for the quality control of the tablets.Methods HPLC was performed for the determination of the alkaline-dissolved stability of curcumin with acetonitrile-acetic acid at volume coefficient of 4％ (48 ∶ 52) as mobile phase,the detection wavelength being 430 nm.The alkalinedegraded products were tested by HPLC-MS assembling with electron spray ionization (ESI) and quadrupole timeof-flight (Q-TOF) in the scan range of 100-2 000 m/z.Results The degradation of curcumin in the alkaline solution was increased with the temperature.When the temperature was below 20 ℃,the degradation slowed down,while when the temperature reached to 80 ℃,curcumin was degraded completely within 2 h.The probable degradation products in the alkaline solution were p-hydroxy benzaldehyde,vanillin,p-coumaric acid,ferulic acid,et al.Conclusion Curcmin compounds are instable in aqueous alkali.To obtain the high-quality of Jianghuang Qingzhi Tablets with high content of curcumin and less degraded products,the alkaline-solution temperature should be controlled below 20 ℃.

Objective To investigate the effects and anti-atherosclerotic mechanism of rosiglitazone on the expression of ATP-binding cassette transporter A1 (ABCA1) and reverse cholesterol transport (RCT) in atherosclerotic rabbits. Methods Twelve rabbits were randomly divided into two groups (6 each): control group (only high cholesterol diet for 6 weeks), rosiglitazone group [high cholesterol diet plus rosiglitazone 0.5mg/(kg?d) for 6 weeks]. ABCA1 expression and [3H] cholesterol efflux rates were evaluated by flow cytometry and liquid scintillation spectrometry, respectively. Enzymatic methods were used to assay serum lipids levels and cholesterol contents in tissues, and the atherosclerotic area of aorta was calculated by professional image analysis software. Results For the rabbits of both control and rosiglitazone group, the serum levels of high-density lipoprotein cholesterol (HDL-C), non-high-density lipoprotein cholesterol (NHDL-C) and apolipoprotein A1 (apoA1) significantly went up when they took their cholesterol rich diet for 6 weeks (P0.05). Compared with control group, the ABCA1 expressions in monocytes, peritoneal macrophages, adipocytes and hepatocytes, as well as the cholesterol efflux rates in peritoneal macrophages, adipocytes and hepatocytes increased significantly (P
