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.

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.

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.

Pancreatic cancer has a strong ability of invasive and metastasis,and the mechanism is still not completely clear.It has been demonstrated that aberrant expression of microRNAs(miRNA) is closely associated with the occurrence,development and metastasis of pancreatic cancer.The reveal of miRNA mechanism related to the metastasis of pancreatic cancer would provide a new approach to the treatment of pancreatic cancer.

Objective To study the effect of 3％ hypertonic saline(HS) and 20％ mannitol on cerebral oxygen metabolism in patients undergoing neurosurgery for supratentorial glioma.Methods 56 patients undergoing neurosurgery for supratentorial glioma were evenly divided into two groups.Group A(n =28) was treated by 3％ hypertonic saline(5.35ml/kg).Group B (n =28) was treated by 20％ mannitol(1 g/kg).CSFP was tested before hypertonic saline or mannitol infusion (T0),immediately (T1),15,30,60,120min after infusion (T2 ～5).Various blood-gas indexes were observed at To,T3 ～5.CaO2,CjvO2,Da-jvO2 and CERO2 were calculated.Results CSFP significantly dropped from T2 to T5 in both groups (P ＜ 0.05).Da-jvO2 and CERO2 were significantly reduced at T4～5 in both groups (P ＜ 0.05).There was no significant difference between the two groups.Conclusion 3 ％ HS is as efficient as 20％ mannitol in reducing intracranial pressure and improving cerebral oxygen metabolism in patients undergoing neurosurgery for supratentorial glioma.

Objective To determine the brain protective effects of inhalation anesthetic pretreatment in infants undergoing open-heart surgery under extracorporeal circulation (ECC).Methods Forty-five infants (no more than 3 years old) with congenital heart diseases who received surgical treatment were divided into 3 groups by table of random digit,sevoflurane pretreatment group (group S,15 cases),isoflurane pretreatment group (group Ⅰ,15 cases) and control group (group C,15 cases).In pretreatment group,all infants had been inhaled 1.0-1.5 MAC sevoflurane or isoflurane continually for over 60 min after intubation,while group C did not receive pretreatment.Blood samples were taken before (T1) and in 5 min after ECC (T2),occlusion of aorta (T3),30 min after ECC (T4),end ofECC (T4),and 6 and 24 h after the end of ECC (T6 and T7).Serum levels of S 100 β protein and neurone specific enolase (NSE) were measured by enzyme-linked immunosorbent assay.Results There was no significant difference in the serum levels of S100β protein and NSE among the 3 groups in T1 (P＞0.05).There was no significant difference in the serum levels of S100β protein and NSE in group S and group Ⅰ between T1 and T2-7 (P＞ 0.05).There was no significant difference in the serum levels of S100 β protein and NSE in T2-7 between group S and group Ⅰ (P ＞ 0.05).In group C,there were significant differences in the serum levels of S100 β protein in T4-6 and NSE in T4-7 than those in T1 (P＜ 0.05).In T4-6,the serum levels of S100 β protein and NSE in group S and group Ⅰ were significantly lower than those in group C [S100 β protein:(0.45 ± 0.31),(0.47 ± 0.35) μ g/L vs.(0.73 ± 0.31) μ g/L,(0.53 ± 0.33),(0.54 ± 0.36) μ g/L vs.(0.91 ± 0.30) μ g/L,(0.47 ± 0.34),(0.49 ±0.35) μ g/L vs.(0.79 ± 0.40) μ g/L,P ＜ 0.05； NSE:(3.26 ± 1.34),(3.32 ± 1.34) μ g/L vs.(7.20 ± 2.71)μ g/L,(5.57 ± 1.49),(5.61 ± 1.52) μ g/L vs.(7.68 ± 3.68) μ g/L,(2.29 ± 1.21),(2.34 ± 1.22) μ g/L vs.(9.46 ± 4.61) μg/L,P ＜ 0.05].Conclusion Sevoflurane or isoflurane pretreatment significantly decreases the serum levels of S100 β protein and NSE during open-heart operation in infants with ECC.
