Objective:To observe the proliferation and the free intracellular calcium ion concentration of osteoblast under the effect of static magnetic field and discuss the possible mechanism of the static magnetic field on promoted the proliferative function. Methods: The MTT assay was used to measure the rate of the proliferation on different magnetic field intensity(0, 0.026, 0.044, 0.090 T)and action time(24, 48, 72 h).The fluorescence double wavelength spectrophotometer was used to measure the concentration of intracellular calcium ion. The data obtained were analyzed for ANOVA and t-test using SPSS 11.0 software package. Results: Osteoblasts in group 0.044 T appeared significant proliferation within 48 h(P

Extensive use of tributyltin (TBT) has caused serious environmental pollution, which is harmful to human and other organisms. As a cytotoxic chemical, an important mode for TBT effects on the cells is to induce apoptosis. The present paper mainly reviewed the mechanism by which TBT induces apoptosis at low concentration.

Objective To observe the clinical efficacy of breeze heat treatment with site blood circulation for abdominal purpura allergic acupoint application therapy. Methods 96 patients were randomly divided into treatment and control group ,with 48 people in each. Both groups received traditional Chinese medicine with conventional therapy. Control group was given oral medicine treatment and acupoint application while the treatment group was given enema treatment. Clinical parameters observed includes degree of symptoms released ,the number of days in hospital and laboratory test results. Results The number of days in treatment group and hospital stay significantly decreased compared with control group (P<0.05). In terms of laboratory tests,the degree of improve?ment of the treatment group than the control group was statistically significant (P<0.05). Conclusions Treatment of dispersing heat blood circulation acupoint sticking with the treatment for abdominal type allergic purpura can sig?nificantly improve symptoms and laboratory tests ,with no obvious adverse reactions.

Intrahepatic cholangiocarcinoma is an uncommon malignant tumor,and its incidence has been increasing in the recent 30 years. Since patients have no specific clinical manifestations in early stage,the diagnosis of this disease is often very difficult,with a low rate of radical resection in late stage and poor prognosis.Therefore,as for patients with intrahepatic cholangiocarcinoma,early screening and diag-nosis is of vital importance.Imaging examination is an important method for the diagnosis of intrahepatic cholangiocarcinoma,and when com-bined with laboratory markers and pathological examination,it can increase diagnostic rate and reduce the rate of missed diagnosis.It is im-portant in clinical practice to select reasonable methods based on the patient′s actual condition.

Objective To evaluate the result of radiotherapy for primary cardiac neoplasm.Methods A patients with primary malignant mucinous Schwannoma in th left ventriclular wall had been treated by conservative surgery. He,then,received fast neutron radiotherapy one year after wards. Radiotherapy was given through opposing anterior and posterior fields of 7.8 cm?7.8 cm. The total radiation dose was 1?004.95 ncGy with 11 fractions of 100 ncGy in 48 days.Results The function of the patient's heart recovered after treatment. The patients has been followed for 5 years without evidence of recurrence or distance metastased. Conclusion Fast neutron radiotherapy is effective in the treatment of primary cardiac neoplasms by surgery combined with postoperative radiotherapy. It could improve the prognosis of patients with primary cardiac neoplasms.

Objective To investigate the signaling transduction mechanisms of inhibiting effect of radiation on vascular smooth muscle cells(VSMC).Methods Cell culture in vitro and semi quantitative reverse transcription polymerase chain reaction(RT PCR) were used to observe the dynamic change of VSMC focal adhesion kinase(FAK) on the mRNA expression level and result of the control group as compared to those of the irradiation ones at 2.5,10,15,20 Gy.Results Dose of 2～20?Gy irradiation down regulated the expression of FAK mRNA. At hour 48 after 2～20?Gy irradiation,the FAK mRNA expressions were all less than the control ones(F=364.21,P

Purpose: To observe the long-term and recent clinical effect of needle-warming method plus functional training in the treatment of osteoarthritis of the knee joint. Methods:After 106 cases of the patients were divided into the needle-warming group and comprehensive group by the order of their first visit, the needle-warming group was treated by the needle-wanning method and the comprehensive group was treated by the needle-warming method plus functional training. After ten treatments, the clinical data in the two groups were evaluated upon Lequesne scale before and after the treatments. Three months later, follow-up survey was given to process the statistic management of the reoccurrence rate of the symptoms.Results: In the two groups after the treatment, the symptoms of the knee joint and daily life ability were obviously improved than the respective conditions before the treatment, and the integral decreased (P＜0.05), with no significant difference (P＞0.05) between the two groups. In the follow-up survey, there was a difference (P＜0.05) between the two groups in the positive rate of the recurrent symptoms. Conclusion: Certain therapeutic effect exists in the treatment of osteoarthritis of the knee joint by the needle-warming method. If functional training is combined,the therapeutic effect would be more stable, without easy reoccurrence.

Objective: To study the role of adrenomedullin(ADM) in normal early pregnancy. Methods: Plasma concentrations of ADM were measured in 30 normal early pregnancy and 10 non-pregnant women by radioimmunoassay. The expression of ADM?ADM mRNA and ADMR mRNA in villus of normal early pregnancy were determined by immunohistochemistry and in situ hybridization respectively. Results: The plasma concentration of ADM in normal early pregnancy was significantly higher than that of normal non-pregnant women (P

OBJECTIVE To strengthen the management of medical refuse in order to control the onset of hospital(infection.) METHODS It has been done including setting up special tissue,formulating supervising system,strengthening training,carrying out supervising measures and strengthening examination and inspection.(RESULTS) It could prevent hospital infection effectively to regulate the whole course of the medical refuses(collection,) storage,dealing with and registration.CONCLUSIONS It is very important to strengthen the management of medical refuse in order to prevent hospital infection.

2 months) was 93%(14/15); both 1- and 2-year local control rates were 83%; and 1- and 2-year survival rates were 72.9% and 62.5%, respectively. The median survival time was 32 months. Three patients had distant metastasis. Five patients died of lung metastasis (1 case) or multiple organ failure (4 cases). No complication or side-effect was observed in the patients, except skin ulceration in one patient. Conclusions Interstitial implantation of ~(125)I seed combined with or without external beam radiation therapy is convenient, effective, safe, and minimally invasive for soft tissue tumor, especially for metastatic or recurrent tumors.
