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.

Objective To explore the changes of T-lymphocyte subsets,D-Dimer and immunoglobulin in mycoplasma pneumonia children and its significance.Methods The levels of T lymphocyte subsets (CD3 +、CD4 +、CD8 +、CD4 +/CD8 +)in 50 children with mycoplasma pneumonia (MPP Group)and 50 healthy children were detected by flow cytometry;The levels of D-Dimer were detected by immunoturbidimetry;The levels of serum immunoglobulin were detected by immune turbidimetric method.Results The results of T lymphocyte subsets:Compared with normal control group, CD3 +and CD4 +peripheral blood cells in MPP group were significantly declined(P<0.001)、CD8 +cells were increased slightly,but with no significant difference、CD4 +/CD8 +ratios were decreased slightly.The results of D-Dimer:Compared with normal control group,the levels of D-Dimer in MPP group were significantly escalated(P<0.001).The results of immunoglobulin:IgA and IgMin MPP group were both significantly higher than those of normal group,but IgG was not different from that in normal group.Conclusion Children with mycoplasma pneumonia have immune disorder,which may generate abnormal clotting.Therefore,besides the conventional anti-mycoplasma pneumonia treatment,we need to detect the levels of D-Dimer according to the clinical symptoms and disease progression and strength the regulation and treatment of the immune system.

Objective To investigate the effect of mycophenolic acid (MPA) on the proliferation of rat pulmonary microvascular endothelial cells (PMVECs) and the effects of MPA on the secretion of endothelin-1 (ET-1) and interleukin-6 (IL-6).Methods PMVECs were cultured by tissue-sticking method.Cells were divided into 5 groups,named as the control group,low-dose MPA group,moderate-dose MPA group,highdose MPA group and super high-dose MPA group,according to the final concentration of MPA (0,0.1,1,10 and 100 μmol/L,respectively).The proliferation of rat PMVECs was detected by cell counting kit-8 (CCK-8).The ET-1 and IL-6 secretion were assessed by radio-immunoassay.One-way analysis of variance was used to detect the differences between the group means.Results The cultured PMVECs of rats in vitro showed fusiform or polygonal in shape,and the expressed factor Ⅷ associated antigen stain was positive.At 24 h,the A values of the 5 groups (from control group to super high-dose MPA group) were 1.15±0.20,1.20±0.13,0.88±0.20,0.62±0.05 and 0.56±0.10,respectively,there was no significant difference in the A values on 450 nm between the control group and the low-dose MPA group (P=0.388),as well as the high-dose MPA group and super high-dose MPA group (P=0.292),but there were significant differences between any other two groups (P＜0.01).At 48 h,the A values of the 5 groups (from control group to super high-dose MPA group)were 2.61±0.21,2.52±0.23,1.99±0.17,0.84±0.16 and 0.65±0.12,respectively,there was no significant difference in the A values on 450 nm between the control group and low-dose MPA group (P=0.094),but there were significant differences in the A values between any other two groups (P＜0.01).At 72 h,the A values of the 5 groups (from control group to super high-dose MPA group) were 2.62±0.24,2.62±0.19,2.37± 0.38,0.79±0.17 and 0.61±0.17,respectively,there was no significant difference in the A values on 450 nm between the control group and low-dose MPA group (P=0.931),but there were significant differences in the A values between any other two groups (P＜0.05).There were no significant differences in the ET-1 concentrations between the control group and low-dose MPA group (P=0.156),and high-dose MPA group and super high-dose MPA group (P=0.262),but there were significant differences in the concentrations between any other two groups (P＜0.01).There were no significant differences in the IL-6 concentrations of the five groups between any of the two groups (P＞0.05).Conclusion MPA can inhibit fetal bovine serum induced rat PMVECs proliferation and the secretion of ET-1 in a dose-dependent manner.

The assessment of right heart function plays an important role in diagnoses, therapeutic decision-making, curative effects and prognoses of many congenital and acquired heart diseases. Recently, a lot of new techniques of echocardiography have been used to evaluate right heart function, such as DTI, MPI, 3-DE, AQ and CUS, which all have their own advantages and disadvantages.

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 discuss the death causes in patients diagnosed initially as mild to moderate craniocerebral trauma. Methods A retrospective study was done on 44 deaths, who arrived at the emergency department with a mild or moderate craniocerebral trauma from 2004 to 2008. There were 35males and nine females at age range of 19-85 years (average 53 years). There were 17 patients with Glasgow coma score (GCS) 13-15 points and 27 with GCS 9-12 points. The causes of injury included road traffic accidents in 18 patients, tumbling in 18, falling from height in six and unknown factors in two respectively. Of all, 18 patients underwent surgical intervention and 26 received conservative therapy.Results The causes of death were cerebral hernia in 25 patients (57%), various complications in 15(34%), multiple trauma in two (5%) and sudden death in two (5%) respectively. Conclusions The primary death cause is cerebral hernia in the patients with mild to moderate craniocerebral trauma.Attention should be paid to prevention and control of complications and multiple trauma during treatment of primary head injury. The prognosis may be badly affected by human factors.
