Objective: To study the compressive strength of 3 kinds of composite resin veneer so as to provide a scientific basis forclinical application. Methods: Thirty anterior teeth were just extracted and then, their labial surfaces of crowns were restoredwith 3 kinds of light cured composite resin veneer. The most stress and compressive strength of the 3 kinds of prosthesiswere tested. Results: The compressive strength of Tetric ceram was higher than those of Charisma and Durafill (P ＜0.05).There was no significant difference between Charisma and Durafill (P＞0.05). Conclusion: The Tetric ceram is a kind ofexcellent prosthetic material as veneer constraction.

Objective To observe the therapeutic effect of astragalus injection on viral myocarditis.MethodsThe treatment group was treated with astragalus injection.The control group was treated with energy mixture and fructose.The Clinical symptoms,physical signs,electrocardiogram outcomes,X-ray films,myocardial enzymes and serum troponin were recorded before and after treatment.ResultsThe total effective rates were 94% and 74% in the treatment and control group respectively(P

Objective To observe the therapeutic efficacy of Le-Mai-Ke-Li in patients with angina pectoris.Methods 50 patients with angina pectoris were treated by Le-Mai-Ke-Li and the symptoms,ECG(ischemic ST-T changes),holter ECG,blood viscosity and blood fat were recorded.Results The total efficacy of Le-Mai-Ke-Li of improving angina pectoris amounted to 94%,of improving ECG amounted to 72%.The improving time(minutes) of holter ECG was from(146.27土20.16) to(39.14土5.86).The therapeutic efficacy of Le-Mai-Ke-Li was higher than that of isosorbidi mononitratis with significant difference between these two drugs(P

After 56 cases of infantile constipation were divided into the pattern of stagnation of heat in the stomach and intestines, pattern of obstruction of qi activity and pattern of deficiency in both qi and yin, the treatments were given by infantile Tuina techniques on the infantile points of Dachang (Extra),Zhongwan (CV 12), Bagua (Extra), Qijiegu (Extra), Chengshan (BL 57), Zusanli (ST 36) and Yingxiang (LI 20). The results showed cure in 45 cases, effectiveness in 9 cases, failure in 2 cases and the total effective rate was 96.5%.

OBJECTIVE To detect the effect of AcasinTM dressing on surgical incision healing.METHODS Eighty cases with types Ⅰand Ⅱsurgical incision operation at outpatient clinic were divided into study group and control group.AcasinTM dressing was applied to study group while common aseptic dressing was applied to control group.The bacterial test results and the healing condition of the incision were observed.RESULTS The bacterial tests were negative in study group,the average healing time was 7.32?1.74 days,the healed rate of stage Ⅰ was 100.00%.The bacterial tests were positive in 10 cases of control group,10 cases had redness in incision,5 cases with drainage leakage,the average healing time was 10.12?2.24 days,The healed rate of stage Ⅰ was 90.00%.CONCLUSIONS AcasinTM dressing can eridicate pathogenic organism in surgical incision and suture,It can effectively prevent incision infection,and promote stage Ⅰincision healing.It is worth spread in clinic.

Chitosan, deacetylated derivative of chitin, is a kind of natural polysaccharide polymer. It has advantages of rich source, good biocompatibility and biodegradation. Chitosan can be processed into porous scaffolds used for cell transplantation and tissue regeneration in bone tissue engineering, control-released carrier of growth factors and delivery vector of exogenous genes. Meanwhile, it can also be processed into injectable scaffolds used in bone tissue engineering in the form of microspheres or hydrogel. Chitosan and its derivatives will have broad application prospects in the research field of bone tissue engineering. However, chitosan composite scaffold has poor mechanical function, difficult accuracy control of In vivo degradation, and low efficiency for genetic carrier, chitosan research stays in in vitro tests and in vivo animal experiments. With the development of materials science and life science, chitosan will be widely used for clinical application of bone tissue defect.

The variation of active compounds caused by geographicaland morphological factors are discussed,and a comprehensive evaluation of drug quality of E' sagittatum isgiven.

Objective To isolate and identify the chemical constituents in the polar part of the Ancecotochilus roxburghii.Methods The flavonoids were isolated by column chromatography and their structures were elucidated through spectral analyses such as FAB-MS and NMR.Results Five flavonoids were isolated and identified as quercetin 7-O-?-D-glucoside(Ⅰ),quercetin 3-O-?-D-rutinoside(Ⅱ),isorhamnetin-3,4′-O-?-D-diglucoside(Ⅲ),isorhamnetin-3,7-O-?-D-diglucoside(Ⅳ),and isorhamnetin-7-O-?-D-diglucoside(Ⅴ).Conclusion All the compounds are obtained from A.roxburghii for the first time.

Objective To observe the effect of Guanxin Ⅱ Hao on plasma NO and NOS in dog with myocardial ischemia. Methods 20 dogs of myocardial ischemia were divided into the control group, isosorbidi mononitratis group and the Guanxin Ⅱ Hao group by random. The NO and NOS of serum were measured, before and after treatment. Results In the control group, the level of NO and NOS were higher than that of the isosorbide mononitrate group. There was significant difference between the control group and the Guanxin II Hao groups (P
