Objective: To explore The effect of rate responsive pacemaker in old patients with sick sinus symptom on Quality of life.Methods: 96 patients with sick sinus syndrome and atrioventricular block were enrolled and divided into rate responsive pacing-group and non-rate responsive pacing-group,the Quality of life were analyses by means of GQOLI-74.Results: The heart function were no different in the two groups;The daily maximum movement time and distance,Quality of life were improved significantly in rate responsive pacing-group.Conclusion: The implantation of rate responsive pacemaker can improve health-raltaed quality of life,meet with requirement of life in the elderly patients.

The article introduces a set of efficient English teaching methods through continuous practice and reform.The methods are based on the characteristics of the foreign students.It includes choosing the book in English and compiling English-Chinese bilingualism textbook,question-based and quiz-based teaching in class and reviewing after class and so on.The methods have shown good effects in raising quality of teaching to the international students.At the same time there are some problems in the Lemology teaching.

Objective: To observe the effect of Dan Chi Drink on the changes of CA125,Tumor necrosis factor-a(TNF-?)and Estradiol(E2) Progesterone(P) in patients with endometriosis(EMT).Methods: Forty-two cases with endometriosis were taken in control by themselves,to observe the changes of clinical symptoms and signs of patients with endometriosis and the activity changes of peripheral blood serum CA125,TNF-? and Estradiol(E2) Progesterone(P) before and after therapy.Results: After treatment,the level of CA125 and Estradiol(E2) Progesterone(P) were decreased(P

Objective To explore the therapeutic mechanism of endometriosis (EM) by the treatment of Danchiyin. Methods Forty-two cases with endometriosis were taken in control by themselves, to observe clinical symptoms and signs of patients with endometriosis before and after treatment. The activity of natural killer cell, EMAb and stream of peripheral blood were determined. Results After treatment, the activity of natural killer cell of peripheral blood were significantly increased (P

Objective To reaserch the effect of Danchi capsule on the changes of monocyte chemotactic protein-1 (MCP-1) and tumor necrosis factor-? (TNF-?) and solution intercellular adhesion molecule-1 (sICAM-1) of cell supernatant of eutopic endometrium in patients with edndometriosis. Methods Cells were divied into five groups:Danchi large, medium, small dosage group, blank group and dannazol group in control, detected by ELISA method and MTT method. To observe the levels of MCP-1, TNF-?and sICAM-1 of eutopic endometrial cells and cell activity. Results The group of DanChi large dosage decreased significantly the level of TNF-?, the group of Danchi large and medium dosage decreased the level of MCP-1 significantly. Conclusion Danchi capsule may descend and inhibite the production and activity of these cytokines which involved in three steps: adhesion and implantation-angiogenesis-progression and infiltration, then inhibit adhesion and implantation of endometrial cells.

Objective To investigate the effect on thyrotropin (TSH) levels of pregnant women and their newborns in different delivery ways. Methods The serum TSH levels of 213 pregnant women and the umbilical cord blood TSH levels of their newborns (140 cases from normal vaginal delivery, 38 cases from cesarean section, 35 cases from low forceps delivery) were tested by immunoradiometric assay. Urinary iodine was detected from pregnant women before delivery. Results In pregnant women, the mean serum level of TSH in the forceps group [(4 13?0 69) mU/L] was significantly higher than those of the normal birth group [(2 58?0 87) mU/L, P

The achievements in recent research on osteogenetic induction of extracorporeal shock wave (SW) are introduced. The mechanism of osteogenesis inducted by SW and its effect of bone repairing are explained emphatically. Besides, the development prospects of SW in healing human disease are described and is indicated that SW will maybe a clinical method for osteoporosis and other disease in orthopedics according to its osteogenetic mechanism.

Seed cell, biomaterials, constructing of tissue are three essential elements of tissue engineering. The core is the technology of tissue constructing. Bioreactor for tissue engineering is a sort of systematic equipment constructing ttissues in vitro. Cardiac tissue engineering may hold great potentials for not only replacing or supporting an infarcted cardiac tissue but also treating and saving the lives of patients with heart diseases. This paper mainly introduced the progress of domestic and international technology for constructing engineered cardiac tissue in vitro, especially in the research of bioreactors used for engineered cardiac tissue construction.

BACKGROUND:It needs strong anchorage for shifting mandibular molar in orthodontics,which is a difficult problem to clinical orthodontic doctors.OBJECTIVE:To evaluate clinical effects and the characters by micro-implant anchorage during mandibular molars mesialization in Class Ⅰ malocclusal patients.METHODS:A total of 24 micro-implants were embedded mandibular bones between mandibular second premolar and mandibular first premolar of 15 Angle Ⅰ malocclusal patients as clinical anchorages for mesializing mandibular molars.The position changes of mandibular molars were measured from mesiodistal direction and vertical direction,and the implant anchorage loss was evaluated by maxillary central incisor.RESULTS AND CONCLUSION:The course of treatment was 10.4 months,and the velocity of mandibular second molar mesializing was 0.8 mm per month,with 8.5 mm in mesiodistal direction,there was no changes in the vertical direction.The distal tipping angle of molar was 2.5°,and the mandibular central incisor did not move.The method successfully mesialized mandibular molars to appropriate positions.No anchorage loss was found,The implant plays absolute anchorage during mandibular molar mesialization.
