To investigate the influence of mixing ratios on the hardness,wear resistance and compressive strength of the cements clinically used,Zinc Oxide Eugenol cement,Glass ionomer cements,Zinc Phosphate Cement,and Dual-curing composite cement were mixed at different ratios separately,then made into test pieces.Vickers hardness,wear resistance and compressive strength of these test pieces were measured by related machines.The results showed that vickers hardness,wear resistance and compressive strength of Zinc Oxide Eugenol cement,Glass ionomer cements and Zinc Phosphate Cement reduced with the decrease of powder/liquid ratios.As to Dual-curing composite cement,Vickers hardness,wear resistance and compressive strength decreased with the difference between A/B ratio and 1∶1 increase.Conclusively,mixing ratios could influence the mechanical proprieties of the cements clinical used,so the use of cements should be under the instructions of the product.

Objective To observe the curative effect in patients with systemic lupus erythematosus(SLE) complicated by moderate or severe thrombocytopenia with a blood platelet count(BPC) of under 50 × 109/L and analyze its related factors. Methods We retrospectively analyzed the clinical data on 109 SLE patients with mod-erate or severe thrombocytopenia. Results Of the 109 patients,82(75.2%)had complete response(CR),15 (13.8%)had partial response(PR),and 12(11.0%)had no response(NR),respectively. As compared with the CR+PR group,the NR group had a higher incidence rate of decreased bone marrow megakaryocyte(P < 0.05). However,there were no significant differences between the two groups in SLEDAI scores,rates of positive PAIg and ACA,and levels of C3 and C4(P>0.05 for all comparisons). The total effectiveness rate did not differ signifi-cantly between MP pulse therapy and high-dose corticosteroid therapy. Conclusions A decrease in bone marrow megakaryocytes can be an adverse factorfor affecting the efficacy in patients with SLE complicated by moderate or severe thrombocytopenia.

Objective To investigate the numbers, sizes and types distribution of diatoms in drowned and postmortem immersed rabbits’ lungs. Methods Sixty-two rabbits were randomly divided into drowning group (n=30), postmortem immersion group (n=30) and land death group (n=2), and the diatoms in each lung lobe were analyzed quantitatively and qualitatively by microwave digestion and scanning electron microscopy. Results In the drowning group, the diatoms were detected in each lung lobe with Cyclotella and Melosira in the majority. In the postmortem immersion group, Cyclotella was in the majority. And the diatoms weren’t detected in some lung lobes in postmortem immersion. There were significant dif-ferences in the detection rates of upper lobe of left lung, middle lobe and cardiac lobe of right lung in two groups (P<0.05). Conclusion Based on the microwave digestion and scanning electron microscopy, the numbers, sizes and types distribution of diatoms in drowned and postmortem immersed rabbits ’ lungs can be analyzed and used as references for testing theory.

Oversea students with rare languages are characterized by severe language barrier,difficulty in study,difficulty in administration,weakness of basic medicine teaching,and lack of standardized clinical manipulation.Based on these characters,reform of clinical teaching was undertaken during the teaching process.Definite teaching principles were made,teaching methods were innovated,and teaching materials of various media were carefully chosen according to the teaching situation,and were renewed continuously.Good teaching effect was achieved,and all the oversea students with rare languages were satisfied with our teaching.

Objective To discuss the clinical significance of postoperative application of gastrointestinal decompression after anastomosis of lower digestive tract. Methods Three hundred and sixty-eight patients undergoing excision and anastomosis of lower digestive tract were divided into two groups: the group with postoperative gastrointestinal decompression and the group without it. The clinical therapeutic outcomes and incidences of complications were compared between the two groups. Results The volume of gastric juice in the decompression group was about 200 ml every day after operation. Both groups had a smaller abdomenal circumference before operation than after operation ( P

Objective To investigate the acute effect of dialysate calcium concentration on calcium balance and blood pressure(BP) of maintenance hemodialysis(MHD) patients with normal serum tCa,and to provide scien- tific basis for individualized calcium concentration dialysate formula.Methods For 4 weeks,dialysate with different calcium concentrations as DCa 1.25,DCa 1.5 and DCa 1.75 was used in 15 stable MHD patients.Arterial blood pressure was measured before and after each dialysis session,and every 30 minutes during hemodialysis session.Serum total calcium and ionized calcium were assessed before and after each dialysis session with different calcium concen- trations dialysate.Results With the DCa 1.2.5,BP,serum tCa and iCa decreased as compared with pre-dialysis val- ues(P
