ABSTRACT
Objective To investigate the clinical efficacy of felodipine combined with irbesartan in the treat-ment of hypertension and its effect on atherosclerosis in remission .Methods 100 patients with hypertension were divided into the observation group and the control group .The control group was given the felodipine treatment ,the obser vation group was given felodipine treatment based on the control group .The treatment effect ,changes of blood control and carotid artery intima-media thickness were compared between the two groups .Results The total effective rate of the observation group was 90.0%,which was significantly higher than 72% of the control group (χ2 =3.85,P<0.05).After treatment,the systolic pressure,diastolic pressure of the observation group were significantly lower than those in the control group(t=4.21,5.05,all P<0.05).After treatment,the size,thickness of carotid artery plaque of the observation group were significantly lower than those of the control group (t =1.98,5.05,all P <0.05). Conclusion Felodipine combined with irbesartan can significantly improve the therapeutic effect of hypertensive patients,and can improve the control of blood pressure ,slow the progression of atherosclerosis .
ABSTRACT
The bones are the most common sites of breast cancer metastasis. Upon arrival within the bone microenvironment, breast cancer cells coordinate the activities of stromal cells, resulting in an increase in osteoclast activity and bone matrix degradation. In late stages of bone metastasis, breast cancer cells induce apoptosis in osteoblasts, which further exacerbates bone loss. However, in early stages, breast cancer cells induce osteoblasts to secrete inflammatory cytokines purported to drive tumor progression. To more thoroughly evaluate the role of osteoblasts in early stages of breast cancer metastasis to the bones, we used green fluorescent protein-labeled human breast cancer cell lines MDA-MB-231 and MDA-MB-435, which both induce osteolysis after intra-femoral injection in athymic mice, and the murine pre-osteoblastic cell line MC3T3-E1 to modulate osteoblast populations at the sites of breast cancer metastasis. Breast cancer cells were injected directly into the femur with or without equal numbers of MC3T3-E1 cells. Tumors grew significantly larger when co-injected with breast cancer cells and MC3T3-E1 cells than injected with breast cancer cells alone. Osteolysis was induced in both groups, indicating that MC3T3-E1 cells did not block the ability of breast cancer cells to cause bone destruction. MC3T3-E1 cells promoted tumor growth out of the bone into the extraosseous stroma. These data suggest that breast cancer cells and osteoblasts communicate during early stages of bone metastasis and promote tumor growth.

Objective: To evaluate the therapeutic effect of combining use of acupuncture and drugs on rheumatoid arthritis(RA) in the early and the active stages of by the imaging of bone and joint with 99m TC-methlene diphosphate(MDP). Methods: 102 cases of RA in the early and the active stages were randomly allocated into the compound Fengshining group (Group A),acupuncture group(Group B), and compound Fengshining plus acupuncture group(Group C).They were treated for 30 days. All patients were examined before treatment and after treatment by 99m TC-MDP imaging of the whole body, hands and feet, and analyzing method of random interested region was used to count the ratio of radioactivity in the affected area of RA to radioactivity in adjacent normal bone(T/TN). Meanwhile, joint swelling index, joint tenderness index, morning stiffness, gripping force, and erythrocyte sedimentation rate (ESR) were also observed. Results: T/TN of the Group A after treatments had no significant difference comparing with that before treatment(t = 1.35, P＞0.05), while the Group B and C had significant differences(t = 5.31, t=8.97, P＜0.01). The changes of clinical and experimental examination in the Group C had more significant differences than those in the Group A and B(P＜0.05).Conclusion: Acupuncture therapy could promote RA recovery, and combining use of acupuncture and compound Fengshining had better effect.
ABSTRACT
Objective: In order to observe the clinical therapeutic effect of acupuncture plus ear point-sticking for simple obesity. Methods: Fifty-two cases of the patients with simple obesity were treated by acupuncture and ear point-sticking method for one course. Results:After the treatments, the results showed remarkable effect in 22 cases, effect in 25 cases and failure in 5 cases, and the total effective rate was 90.4%. There was no obvious change in various indexes of the body in the male and female patients before and after the treatment.Conclusion: Acupuncture plus ear point-sticking for simple obesity is stable in the therapeutic effect, simple and safe in application, without side effects, and cheap in cost and needs to be greatly popularized.
