Objective: 139 documents (10,646 cases of angina pectoris in patients with coronary heart disease) which were treated with traditional Chinese medicine (TCM) of angina pectoris were researched, the application and existing problems of TCM evaluation standards of the efficacy of angina pectoris were studied to determine constructive items (candidate indicatrix) of TCM evaluation standards. Methods: The efficacy evaluation database of angina pectoris was established by the literature search and the software Epidata2.0, recorded in the database, and statistical analysed. Results: There are many kinds of evaluation standards of TCM efficacy of angina pectoris, but the utilization rate of each standard is lower than 40%. The main constructive item in evaluation standards of angina pectoris should include: the effect of the disease, syndrome effects, physical and chemical indicatrix, important clinical event, quality of life, and so on. Conclusion: The current evaluation standards of TCM efficacy of angina pectoris can not meet the clinical needs. A received evaluation standard should be established. The evaluation of TCM efficacy of angina pectoris should adopt integrated multi-dimensional index system.

Objective To simulate the solution drought stress conditions with polyethylene glycol (PEG) 6000 for study on the seed germination of Cassia occidentalis.Methods The seed of C.occidentalis was treated with 5% and 10% PEG 6000,respectively,then the germination rate,the activity of superoxide dismutase (SOD),peroxidase (POD),and content of malondialdehyde (MDA) were measured.Results Compared with the same period of the control,soaking with 5% PEG 6000 for 5 h could increase the activity of SOD and POD,decrease the content of MDA.PEG Pretreatment could decrease free radical accumulation and make cell membrane system less damaged in the course of absorbing water in seed.Conclusion Soaking with 5% PEG 6000 for 5 h could increase the seed germination rate of C.occidentalis.

BACKGROUND:Currently, there are many studies on colapsed repair, but a systematic and horizontal comparison is not reported yet. OBJECTIVE: To compare the effect of conventional resin adhesive, resin adhesive+silane coupling agent and adjacent surface open part of the crown on colapsed repair through clinical trial and in vitro experiment. METHODS: (1) Clinical trial: 90 patients with porcelain colapse were randomized into three groups, and respectively treated with conventional resin adhesive, resin adhesive+silane coupling agent and adjacent surface open part of the crown. Success rate was measured and compared among three groups at 1 year after repair. (2) In vitro test: Twenty test specimens were equaly divided into two groups, and treated with conventional resin adhesive and resin adhesive+silane coupling agent, respectively. Then, shear strength was detected in the two groups. Twenty double-crown specimens were equaly divided into four groups. The first three groups were treated with sand blasting, silane coupling agent and their combination treatment, respectively; the rest group had no treatment (control group). After repair, the tensile strength of each specimen was detected.RESULTS AND CONCLUSION:The success rate of colapsed repair was 37% for conventional resin adhesive, 90% for resin adhesive+silane coupling agent and 100% for adjacent surface open part of the crown. The shear strength was (13.978±0.343) MPa for the conventional resin adhesive and (10.058±0.64) MPa for resin adhesive+silane coupling agent, and there was a significant difference between two methods (P < 0.01). The tensile strength was (0.68±0.04) kN in the control group, (1.00±0.02) kN in the sand blasting group, (1.31±0.08) kN in silane coupling agent group, and (1.09±0.04) kN in the combination group, and there was a significant differences between groups (P < 0.01). Experimental results show that the silane coupling agent+resin adhesive treatment and adjacent surface open part of the crown are superior to conventional resin adhesive.

Objective To investigate the effects of heme oxygenase-1 (HO-1) transduced by cell penetrating peptide PEP-1 on renal ischemia/reperfusion (I/R) injury in rats.Methods Eighteen male Sprague-Dawley rats,aged 7-9 weeks,weighing 210-260 g,were randomly divided into 3 groups (n =6 each):sham operation group (group S),renal I/R injury group (group I/R) and fusion protein PEP-1/HO-I + I/R group (group HO).I/R injury was produced by occluding bilateral renal arteries for 45 min followed by reperfusion for 6 h.The fusion protein PEP-1/HO-1 was injected via the left iliac vein 30 min prior to ischemia in group HO.Bilateral renal arteries were only exposed but not occluded in group C.Blood samples were collected from the right common carotid artery at 6 h of reperfusion for determination of serum blood urea nitrogen (BUN) and creatinine (Cr) concentrations.The malondialdehyde (MDA) content,superoxide dismutase (SOD) activity and HO-1 expression in renal tissues were measured.Results Compared with group S,the levels of MDA,serum BUN and Cr were significantly increased,the SOD activity was decreased,and HO-1 expression was up-regulated in groups I/R and HO (P ＜0.05).Compared with group I/R,the levels of MDA,serum BUN and Cr were significantly decreased,the SOD activity was increased,and HO-1 expression was up-regulated in group HO (P ＜ 0.05).Conclusion HO-1 protein can be successfully transduced into renal tissues by PEP-1 and transduced HO-1 protein reduces renal I/R injury by inhibiting lipid peroxidation response.

Objective To investigate the effects of RNA interference (RNAi) targeting angiotensinconverting enzyme (ACE) on blood glucose,insulin resistance,as well as oxidative stress in type 2 diabetic rats.Methods Type 2 diabetic rats were divided into diabetes control group (caudal intravenation with control adenovirus named Ad5),gene treatment group (caudal intravenation with recombinant adenoviral vectors named Ad5-ACE-shRNA,expressing ACE gene-specific shRNA),and enalapril group (intragastric administration with enalapril every day).At the same time,the normal blood glucose control group was set up.All rats were injected two times during the experiment period.Blood glucose was measured before and after the intervention.At the third day of the experiment,expressions of ACE mRNA and protein in pancreas were evaluated by RT-PCR and Western blot,and serum concentrations of ACE and Ang Ⅱ were measured by ELISA.By the end of the experiment,insulin sensitivity index was calculated and expressions of glucose transporter 4 (GLUT4) protein of epididymal adipose tissue and NAD (P) H (p22phox) protein of pancreas were measured.Results Blood glucose levels in the gene treatment group [(17.8 ±1.1) mmol/L] and the enalapril group [(17.9 ± 1.2) mmol/L] were lower than that in the diabetes control group [(24.9 ± 1.3) mmol/L] when the experiment was finished.ACE mRNA and protein expressions in pancreas of the gene treatment group were significantly decreased compared with the diabetes control group (P ＜ 0.05).Serum concentrations of ACE and Ang Ⅱ in the gene treatment group were (16.37 ± 3.01) ng/ml and (18.24 ± 3.69)pg/ml,significantly lower than those of the diabetes control group [(46.67 ± 3.92) ng/ml and (44.93 ± 4.12) pg/ml respectively,both P＜0.05].Insulin sensitivity indexes of the gene treatment group and the enalapril group were (-5.14 ± 0.41) and (-5.17 ± 0.38),being all significantly higher than that of the diabetes control group (-6.18 ±0.46,both P＜0.05).Expressions of GLUT4 protein in epididymal adipose tissue were higher and expressions of p22phox protein in pancreas were lower in the gene treatment group and the enalapril group than those of the diabetes control group (both P＜0.05).Conclusions RNAi targeting ACE gene may delay the progress of hyperglycaemia and improve the situation of insulin resistance and oxidative stress.The RNAi technology may be used as a new strategy of gene therapy for diabetes mellitus.
