The animal experiments,clinical researches and epidemiological investigations indicated that genistein has the effect for prevention and treatment of osteoporosis,cardiovascular disease and cancer.Genistein can inhibit cellular and humoral immunity and can regulate cell apoptosis.The chemical structure,biological effects and the mechanism of genistein attracted much attention.The current research advance on genistein was summarized and the prospect on the theoretical significance,clinical importance was presented in this paper.

Hypothyroidism is one of the most common endocrine disorders in childbearing or pregnant women.Gestational hypothyroidism can increase the incidence rate of the variety of pregnancy complications and adverse pregnancy outcome.It also can make adverse effects on the fetus and neonate,such as death,placental abruption,fetal malformation,intrauterine growth retardation and preterm,low birth weight,neonatal respiratory distress syndrome,it can also cause abnormal thyroid function of neonate,severely can cause nerve,mental,physical and mental developmental abnormalities and even death.Therefore,it is recommended that childbearing women who are at high risk for pregnancy should strengthen to monitor pregnancy thyroid function and treat as soon as possible in order to reduce the adverse effects on offspring.

OBJECTIVE: To evaluate the current situation and trend of narcotic drug use in our hospital where the authors work in order to provide the reference for scientific management and rational use of these drugs. METHODS: The yearly amount of narcotic drugs administered in the whole hospital, the yearly amount in the separate departments, as well as drug expenditures and ratios between January 2002 and November 2005 were added up and analyzed statistically. RESULTS: The amount of bucinnazine use dominated in the first. The amount of morphine for oral use was increasing year by year. The amount of fentangl transdernal patch use was also bigger and increasing rapidly. However, the amount of pethidine and morphine for injection use was decreasing. CONCLUSION:Analgetics for oral and transdermal use will be the main categories of analgetics in the future.

Long non-coding RNA was initially identified as "noises" of gene transcriptions. However, with the developing researches of ENCODE, it was found that the long non-coding RNAs can regulate the genomic expressions in the form of RNAs in epigenetic, transcription, and post transcriptional levels, which is involved in the regulation of diverse cellular processes and has significant influences on occurrence and precaution of human diseases. This paper introduces functions and features of the long non-coding RNAs, and sums up the internal relation between long non-coding RNAs, diabetes and diabetic complications on the basis of existing researches. These advances can provide the basis for the further understanding of molecular medicine on occurrence and evolution of diabetes.

Vertical root fracture (VRF) is different from odontoclasis caused by trauma or injury. VRF is defined as a complete or incomplete fracture of roots caused by long-term and persistent stimulus, such as excessive forces from mastication or occlusion, improper tooth anatomy, and tooth treatment accident. Early diagnosis of VRF is essential to prevent the absorption of alveolar bone, thereby improving prognosis. Radiographic examination is the most common and effective evaluation method for VRF. Cone beam computed tomography can provide three-dimensional information for fracture details, which are more precise than traditional periapical films. In this paper, we present the radiographic features, differential diagnosis, and new treatment techniques for VRF.

0.05). Other raw scores of MMSE in the vascular dementia group were lower than those in the cerebral infarction group and the normal control group ( P 0.05). P 300 peak latency in the vascular dementia group prolonged significantly as compared with that in the cerebral infarction group and the normal control group ( P

With the increasingly wide application of advanced science and technology, medical equipment, which reflects the overall strength of the hospital and medical activities, becomes more and more important. Medical equipment raises the level of medical care and increases the hospital income; while meantime, it is also bound to be accompanied by a range of purchase and management problems. The problems of medical equipment purchase and management in hospital are analyzed, and improvement opinions about equipment purchase, approval, use, maintenance and rejection are proposed in order to improve the actuality of equipment purchase and management.

OBJECTIVE:To observe the effect of the side-hole hollow bone cement nail on promoting bone fracture healing. METHODS:This experiment was performed in the Third Hospital of Hebei North College from July 2006 to December 2008. Femoral neck samples were obtained from 60 adult corpses of which the patients were dead one year at most with the mean age of 70 years. X-ray examination showed a significant osteoporosis,but no other abnormalities. Hollow nail was provided by Sanyou Medical Apparatus Co.,Ltd.,Shanghai; self-cohesion methyl methacrylate bone cement was provided by Dental Material Factory,the Second Medical University of Shanghai. In the maximal axial pulling-out force group,the hollow nails were directly implanted into 10 femoral neck samples after drilling at the axial center. The polymethyl methacrylate bone cement was inserted into other 10 femoral neck samples after drilling at the axial center,and the side-hole hollow nail were then implanted. The pulling out experiment was performed by AGS-10KN material testing machine to measure the maximal axial pulling-out strength of hollow nail and the maximal loading when the nail was loose during anti-bending cycle experiments. RESULTS:① The maximal axial pulling-out force of 10 femoral neck samples implanting the hollow nail was 471.5-1 070.5 N,with the mean value of (855.0 ? 207.5) N; the maximal axial pulling-out strength of femoral neck samples implanting the side-hole hollow nail added by poly-methyl methacrylate bone cement was 2 023.7-3 572.1 N,with the mean value of (2 943.3 ? 535.8) N. The maximal axial pulling-out strength in the combined group was significantly greater than hollow nail implantation group (P

Bone marrow stromal cells(BMSCs) is a kind of adult stem cells which exists widely in human mesenchymal tissues and have active abilities of self-replication and multi-differentiation. When intervened individually or jointly by certain inducing agents and by the kind of genes, it can differentiate into specific lineage of cells in vitro and the capacity of multilineage differentiation and proliferation does not change. At the same time, with the unique immunological characteristics,it is an ideal seed cell for tissue engineering. In recent years, a lot of studies have proved that BMSCs can not only be induced and differentiate into nerve cells under certain conditions but have a certain structure and function of the nerve cells, which provide a new way in the treatment of nerve system diseases.This paper gives a review of studies on induced differentiation of BMSCs into nerve cells and the functions.
