BACKGROUND:There is no unified conclusion on the efficacy of immediate implantation and restoration. Some studies have shown that the success rate and aesthetic effect of immediate implantation are better than those of delayed implantation. However, in other studies, the immediate implantation has no difference from the delayed implantation, and it also has safety hazards. OBJECTIVE:To observe the clinical efficacy and safety of BLB implant for immediate implantation and delayed implantation. METHODS:Eighty patients undergoing denture implantation and restoration, 35 males and 45 females, aged 20-52 years were equaly divided into research group treated with immediate implantation of BLB implant and control group treated with delayed implantation. Crown restoration was completed at 3 months after implantation. Then, the patients were folowed up for 6 months to observe the implant stability, implantation efficacy and adverse effects. RESULTS AND CONCLUSION:There was no intra-group or intergroup difference in the implant stability quotients of two groups at 1, 3, 6 months after restoration (P> 0.05). The total effective rate was 95% in the research group and 90% in the control group, and there was no significant difference between the two groups (P > 0.05). In the research group, there was one case of gingivitis and one case of lower lip numbness; in the control group, there were two cases of wound infection and one case of lower lip numbness, but there was no difference in the incidence of complications between the two groups (P > 0.05). These findings indicate that BLB implant has good efficacy and safety both in immediate implantation and delayed implantation.

OBJECTIVE:To study the new factor for marketing competition of pharmaceutical enterprises-CSI.METHO_DS:Analysis was based on the domestic and foreign documents,and combined with the actual situations of pharmaceutical enterprises in China.RESULTS & CONCLUSIONS:Only by increasing the level of CSI and establishing the CS ideas,do the medical enterprises succeed in the furiously competitive market.

OBJECTIVE: To study relation between the packaging of pharmaceutical products and the safety of drug use. METHODS: Analysis was based on the relevant documents, and combined with the actual situations in China. RESULTS & CONCLUSION: Only by selecting the appropriate packaging materials, controlling the packaging process effectively and man- aging the package labels, will the safety of drug use be ensured.

Objective To evaluate the relevance between transthoracic echocardiography(TTE)and cardiac catheterization in measuring diameter of patent ductus arteriosus(PDA)and assessing pulmonary artery pressure.Methods The diameter of PDA and the pulmonary artery pressure in 105 patients were observed by TTE and cardiac catheterization,respectively.Results The di-ameter of the narrowest segment of the ductus and pulmonary artery pressure measurements by TTE and cardiac catheterization showed excellent correlation(r=0.782,P<0.01;r=0.810,P<0.01,respectively).Conclusion TTE and cardiac catheterization for measuring diameter of PDA and pulmonary artery pressure show excellent correlation.TTE plays an important role in evaluating pulmonary artery pressure and selecting patients efficiency of PDA occlusion.

Objective To evaluate the diagnostic value of treadmill exercise test for coronary heart disease. Methods The results of coronary angiography, exercise treadmill test, and the main risk factors of 447 patients suspected of coronary heart disease were analyzed. Results Treadmill exercise test for coronary artery stenosis resulted in 90 3% sensitivity, 19 6% specificity, 65 1% positive predictive value, and 55 0% negative predictive value. Compared with patients with single vessel disease, lower, earlier, and longer lasting ST segment depression and less exercise burden for the maximum heart rate were found in those with multiple vessel disease. A total of 72 5% patients with coronary artery lesion (including coronary stenosis and coronary tunica intima lesion) had more than 2 risk factors. Conclusion Treadmill exercise test is a good non invasive method for screening of coronary heart disease: (1) negative result of treadmill exercise test can be used to exclude coronary heart disease, but positive result of treadmill exercise test plus more than 2 risk factors can predict the likelihood of coronary heart disease; (2) the treadmill exercise test can also reflect the degree and the range of coronary artery lesion.

After a description of the demand for qualified health information professionals, the employment of graduates from department of information management and information system in medical colleges and universities, and the importance of writing graduation thesis, the problems in teaching how to write graduation thesis were analyzed with suggestions put forward for their solution. A new teaching model of writing graduation thesis was established according to the growth assessment theory.

Objective To observe the effect of functional exercise guided by self muscle strength in early rehabilitation on patients after total knee arthroplasty (TKA). Methods From September, 2014 to September, 2015, 62 patients after TKA were randomly divided into ex-perimental group (n=31) and control group (n=31). The control group received conventional rehabilitation training, while the experimental group received rehabilitation training under the guidance of their own muscle strength standard. The degrees of swelling and pain seven days after TKA; the muscle strength seven and 15 days after TKA; the range of motion (ROM), the Keen Society Score (KSS) 15 days after TKA;and the postoperative hospital stay were compared. Results There was no significant difference in all the indexes above between two groups before TKA (t<0.960, P>0.05), and all of them improved after TKA (t>3.470, P<0.01). There was no significant difference in the de-grees of swelling (t=1.800, P=0.077) and pain (t=0.840, P=0.404) seven days after TKA. The score of quadriceps strength was higher in the experiment group than in the control group (t>2.280, P<0.05) seven and 15 days after TKA. There was no significant difference in the ROM of the knee and the score of knee between two groups (t>0.850, P>0.05), and the functional score was higher in the experiment group than in the control group (t=5.870, P<0.001) 15 days after TKA. The postoperative hospital stay was shorter in the experiment group (t=7.65, P<0.01). Conclusion Functional exercise under the guidance of their own muscle strength standard could contribute to the improvement of postoperative muscle strength and knee joint function, and shorten the hospitalization stay.
