?Objective: To evaluate the mechanical properties of low noble alloy Au Pd and Ag Pd developed by Stomatological College,Fourth Millitaly Medical University and Xi'an University of Architecture & Techuology. Methods:The two low noble alloys were cast by means of a centrifugal induction furnace into the tensile bars whose dimensions accorded with the standards of China for Dental Casting Precious Metal Alloys. Tensile properties (?b)were determined by means of a conventional testing machine. The 0.2% offset yield strength(?0.2), elongation(?) and microhardness (HV)were determined in a conventional manner. All data were the average of four specimens of each alloy. Results:?b(MPa),?0.2(MPa),?(%) and HV of Au Pd were 485?12.9,365 ?14.8,7.8?1.1 and 220?14.3;those of Ag Pd 550?9.5,435?8.2,13.5?5.4 and 245?15.1,respectivey.Conclusion:The mechanical properties of the two low noble alloys meet the demands of standards and have lower microhardness than natural tooth enamel.

Due to the latent and highly invasive characteristics of liver carcinoma,a majority of patients are frequently not diagnosed until moderate or advanced stage in the disease process,and usually complicate with cirrhosis.Only 15％ -30％ of the patients are eligible for radical resection.The overall survival time is about 3-4 months.Therefore,on the basis of early diagnosis and treatment of liver carcinoma,how to improve the treatment effect of the moderate and advanced liver carcinoma,ameliorate the quality of life and prolong the survival time,becomes the focuses and difficulties both at home and abroad.

The preliminary identification indicated thai there were 15 and 32 kinds of chemical compositions in flowers and leaves of Radix Ginseng, respectively. Meanwhile, their relative content has also been determined.

Objective To compare the contents of Ferulic Acid and Polysaccharide in Angelica Sinensis oliv. with Lotiform Angelica sinensis because of the morphosis related to lateral bud of Angelica Sinensis. Method The contents of Polysaccharide was determined by Polysaccharide-Phenol-Sulfuric acid reaction system. The content of ferulic acid was determined by HPLC. Result There is no significantly difference in the contents of Ferulic Acid and Polysaccharide between Angelica sinensis and lotiform Angelica sinens. Conclusion The contents of Ferulic Acid and Polysaccharide between Angelica Sinensis oliv. and Lotiform Angelica sinensis has no significantly difference because of the morphosis related to lateral bud of Angelica Sinensis.

Objective To observe the clinical efficacy of combining Yuan-Primary and Luo-Connecting points in treating insomnia due to imbalance between heart and kidney, for providing novel method and evidence for the treatment of insomnia with acupuncture-moxibustion.Method Totally 100 insomnia patients due to imbalance between heart and kidney were randomized into a treatment group and a control group, 50 in each. The treatment group was intervened by acupuncture at Yuan-Primary and Luo-Connecting points, while the control group was by conventional acupuncture. The Pittsburgh Sleep Quality Index (PSQI), self-rating anxiety scale (SAS), and self-rating depression scale (SDS) were observed before and after intervention for efficacy evaluation.Result The PSQI item scores were significantly changed after intervention in both groups (P<0.05). The SAS and SDS scores were significantly different from that before treatment in both groups (P<0.05). After treatment, the SAS and SDS scores of the treatment group were significantly different from that of the control group (P<0.05). The recovery rate and total effective rate were 26.0% and 92.0% in the treatment group versus 12.0% and 86.0% in the control group, and there was a significant difference in comparing the recovery rate (P<0.05).Conclusion Combining use of Yuan-Primary and Luo-Connecting points is an effective approach in treating insomnia due to imbalance between heart and kidney.

To introduce composition,the testing principle of the urine analyzer,To reduce the failure rate, extend the service life of the instrument and improve the accuracy of diagnosis. Make the maintenance system ,according to the system of equipment maintenance maintain the urine analyzer daily and monthly. The maintenance plays an important role in reducing the failure rate, extending equipment life and improving the accuracy of diagnosis.

Objective To study the chemical constituents from the roots of Zanthoxylum nitidum.Methods The constituents were isolated and purified by column chromatography.Their structures were identified on the basis of physiochemical properties and spectral data.Results Two benzophenanthridine alkaloids,1,3-bis(8-dihydronitidinyl)-acetone(1)and 8-acetonyldihydrofagaridine(2),have been iso-lated from the roots of Z.nitidum.Conclusion Compounds 1 and 2 are new compounds named nitidumtone A and nitidumtone B.

The human ovarian mucinous cystadenocarcinoma (hOMC) cells were co-cultured with antisense oligodeoxynucleotide (antisense ODN), nonsense ODN, and follicle-stimulating hormone (FSH) at different concentrations for the purpose of observing the effects of antisense ODN to FSH receptor (FSHR) on the proliferation and apoptosis of cultured hOMC cells in vitro. The inhibitory rates of growth were measured by using MTT method on the 2nd, 4th, 6th, 8th and 10th days after the interference of antisense ODN, nonsense ODN, and FSH, respectively. The apoptotic rates and the cell cycles were determined by means of flow cytometry, the apoptosis indexes were detected by using TUNEL, and the expression of caspase-3 was measured by using SP immunohistochemistry. Compared with that in the control group, the proliferative activity of hOMC cells was increased obviously in FSH groups (P<0.05 or P<0.01), decreased distinctly in antisense ODN groups (P<0.05 or P<0.01), and unchanged in nonsense ODN groups, respectively. Meanwhile, antisense ODN could significantly antagonize the FSH-promoted cell proliferative activity (P<0.01). Compared with those in the control group, the apoptotic rates and the expression of caspase-3 were dramatically increased in the mid-and high-dose antisense ODN groups (P<0.05 or P<0.01), while the number of cells in G(1)/G(0) phase was significantly decreased and that in S phase distinctly increased (P<0.01). There was no change in nonsense ODN groups (P>0.05). It was suggested that FSH may improve the development of hOMC cells. However, antisense ODN could inhibit proliferative activity and the FSH-promoted proliferative activity in hOMC cells, at the same time, antisense ODN could inhibit hOMC cell growth by inducing apoptosis.

Objective To study the role of laparoscopic ventrohysteropexy in the treatment of endometriosis with a retroverted uterus. Methods 64 patients with endometriosis diagnosed under laparoscopy were retrospectively analyzed.After performing conservative operative procedures for the treatment of endometriosis,21 patients underwent ventrohysteropexy(group Ⅰ) and 43 patients didn't(groupⅡ).

Objective To explore the causes and possible treatment for subacute coronary stent thrombosis (SST) after percutaneous coronary interventions (PCI) in the races of Han, Uygur and Kazak in Xin Jiang Province. Methods The variables of hemodynamic, blood coagulation, lesions characteristics, the course of operation and relative treatment of 21 cases of different races (Han. Uygur and Kazak) were reviewed and underwent logistic regression analysis.
