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.

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.

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 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.

OBJECTIVE:To investigate the anti-inflammatory and analgesic effects of mongolian medicine Cymbaria dahurica extract. METHODS:96 KM mice(or SD rats)were randomly divided into model group(water),positive control group(aspirin, 0.5 g/kg),C. dahurica ethanol extract (70% ethanol) low-dose,medium-dose and high-dose groups (0.325,0.650,1.300 g/kg, calculated by crude drug) and C. dahurica aqueous extract of the residue of alcohol extraction low-dose, medium-dose and high-dose groups(0.325,0.650,1.300 g/kg,calculated by crude drug). They were given relevant medicine intragastrically,once a day,for consecutive 7 d. The xylene-induced ear edema method was used to determine the degree of ear edema,and egg white-in-duced paw edema method was used to determine paw edema after inducing inflammation 1,2,4,6 h;anti-inflammatory activity of C. dahurica extract was investigated. 96 KM mice were grouped and given medicine with same method;the number of writhing within 20 min was determined by acetic acid writhing method. Another 64 KM mice were grouped with same method,with 8 mice in each group;except positive control group was given tramadol hydrochloride(0.5 g/kg)intragastrically,other groups were given relevant medicine with same method. Pain thresholds of mice were determined by hot-plate test before and after medication 30,45, 60,90 min,and analgesic effects of C. dahurica extract were investigated. RESULTS:Compared with model group,C. dahurica extract could obviously restrain the ear edema of mice and paw edema of rats 6 h after egg white-induced inflammation. Except paw edema of rats in C. dahurica aqueous extract of the residue of alcohol extraction high-dose group was decreased slightly,there was statistical significance among other groups (P<0.05 or P<0.01). C. dahurica extract decreased the number of writhing in mice within 20 min,and extended pain thresholds of mice 30,60,90 min after medication (P<0.05). CONCLUSIONS:Both C. dahurica ethanol extract and aqueous extract of the residue of alcohol extraction posses certain anti-inflammatory and analgesic effects.
