Objective To discuss the effect of community nursing intervention on medication compliance and control rates of blood pressure in patients with essential hypertension.Methods Community nursing intervention was conducted to 73 community patients with essential hypertension. The patients' medication compliance was compared before and after intervention and their control of blood pressure was also observed. Results The difference was statistically significant in the comparison of patients' knowledge of antihypertension and the proper use of antihypertensive drugs before and after intervention. Blood pressure control rate was 80.82%.Conclusions Community nursing intervention can improve patients' medication compliance and effectively control the blood pressure of the patients.

Objective To observe the clinical contraeeption effects of GyneFix IN IUD,MCu IUD and TCu220C IUD.Methods From January 2005 to December 2006,comparative study was carried out by randomly applying 3 different types of IUDs(GyneFix IN,MCu and TCu220C IUD) for 300 healthy women.Follow-up survey was taken after 1,3,6,and 12 months.Results The pregnancy rates with IUD among 3 types of IUDs showed no significant difference(P>0.05).The expulsion rates of GyneFix IN IUD and MCu IUD were lower than that of TCu220C IUD(P<0.01).The removal rate of GyneFix IN IUD and MCu IUD were lower than that of TCu220C IUD(P<0.05).The 12 months cumulative continuation rates of GyneFix IN IUD and MCu IUD were higher than that of TCu220C IUD(P<0.01).Conclusions GyneFix IN IUD and MCu IUD can be recommended for clinical use based upon the advantages of lower pregnancy rate,lower removsl rate because of side-effect and higher cumulative continuation rate.Proper IUD should be selected depending on individuals,in order to increase the contraception effects and decrease the side-effects.

Objective To investigate the effect of plant estrogen on serum hormone levels, NOS and oxidative stress products in patients with uterine fibroids with iron deficiency anemia.Methods 80 cases of hysteromyoma patientswith uterine fibroids with iron deficiency anemia were selected, according to the different medication were randomly divided into experiment group and control group,40 cases in each group.Two groups were treated with anemia correction , mifepristone oral ,and the experiment group were treated on the base of the control group with plant estrogen, 12 weeks for a course.serum sex hormone, NOS, SOD and MDA level were detected.ResuIts Compared with the control group, the indexes of patients in the experimental group were lower(P<0.05), level of serum NOS were higher(P<0.05), level of serum SOD were higher(P<0.05), level of serum MDA were lower ( P<0.05 ) .ConcIusion Plant estrogen can improve the serum levels of serum hormone, NOS and oxidative stress levels of the treatment of uterine fibroids, worthy of clinical promotion.

Objective To study nuclear factor E-2 related factor 2(NrF-2) and heme oxygenase -1(Ho-1) expression and to explore its clinical significance.Methods From February 2016 to June 2016, 176 cases human gastric tissue paraffin blocks selected in department of pathology in Hangzhou Cancer Hospital, including 78 cases of gastric cancer, 78 cases of normal tissue were analyzed.And the expressions of NrF-2 and Ho-1 were detected by immunohistochemistry in two groups of human gastric tissue.Results The levels of NrF-2 and Ho-1 in gastric cancer group were(0.752 ± 0.098),(0.862 ±0.081) were significantly higher than those in normal group(0.381 ±0.068),(0.412 ±0.083);NrF-2, the positive expression rate of Ho-1 in gastric wall invasion degree of T3 +T4 with lymph node metastasis, NTM stage III and IV gastric cancer tissues were significantly increased.The differences were statistically significant ( P <0.05 ) .Conclusion NrF-2 and Ho-1 play the important role in the development of gastric cancer and NrF-2, the positive expression rate of Ho-1 in the gastric carcinoma and gastric wall invasion, lymph node metastasis and NTM staging are closely related.The clinical diagnosis if the combined detection of NrF-2 and Ho-1, is conducive to the early diagnosis of gastric cancer and the prognosis of the disease.

AIM: To observe the effects of ?-MSH on the expression of CD14 and TLR4 mRNA in mou se peritoneal macrophages induced by LPS and explore the mechanisms of ?-MSH ag ainst LPS. METHODS: BALB/C mouse peritoneal macrophages were cultured in the presence of LPS or LPS plus ?-MSH, and the expressions of CD14 and TLR4 mRNA were detected with the m ethod of reverse transcription polymerase chain reaction (RT-PCR). RESULTS: It was found that native murine macrophages o nly expressed a small amount of CD14 and TLR4 mRNA. Both CD14 and TLR4 mRNA expr ession to LPS in mouse macrophages increased significantly than those of contro l group at 6 h and maintained high level until 24 h when they reached to the pea k. Then the expression of CD14 mRNA backed to the normal gene expression baselin e, while TLR4 mRNA had excessive expression at 48 h. In presence of LPS and ?- MSH, the expression of CD14 and TLR4 mRNA decreased remarkably than those of L PS group (P0.05). Only when the dose s of ?-MSH attained to 1, 10 or 100 nmol/L,?-MSH could affect LPS-stimulated e xpression of CD14 and TLR4 mRNA (P0.05). CONCLUSION: These studies suggest that effects of ?-MSH against LPS are associated with its suppressing the critical receptor (CD14 and TLR4) expression of the LPS signal transduction and inhibiting the activation of macrophages.

Probimane was first synthesized and developed in Shanghai Institute of Materia Medica, Chinese Academy of Science as a novel antit umor agent. Male mice were injected iv 〔14C〕 probimane 3.7?105Bq/20g( 5.62? 107Bq/g ) . At 0.5h,higher radioactivities were found in S87 tumor, kidney, bladder, and vertebra, moderate in skim, lung, liver, blood vessel and gut. The radioactivities tended to decre-aseafter 3h except in the tumor, kidney, and gut in which radioactivities persisted. After 12h, only a trace of radioactivity was detected n intestine. The distribution of probimane correlated with its therepeutic efficacy and toxicity.
