Objective To compare the effects of Jianpi Shengxue Granule and Hexue Capsule in treating patients with iron deficiency anemia. Methods All 120 patients with iron deficiency anemia were randomly recruited into group A (treated with Jianpi Shengxue Granule) and group B (treated with Hexue Capsule), with 60 patients in each group. The levels of serum iron (Fe), total iron binding capacity (T IBC), transferrin saturation (TS), transferrin (Tf), ferritin (SF), hemoglobin (Hb) and serum soluble transferrin receptor(sTIR) were observed in both groups. Results Jianpi Shengxue Granule showed better results in treating patients with iron deficiency anemia than Hexue Capsule with significant difference (P<0.05). Conclusion Jianpi Shengxue Granule is effective in treating iron deficiency anemia.

This study examined the effects of Bangdeyun on the expressions of nuclear factor-kappaB (NF-kappaB), interferon-gamma (IFN-gamma) and interleukin-10 (IL-10) in the endometrium of mice with embryo implantation dysfunction (EID) during the implantation time (namely on pregnancy day 5, 6, 7 and 8) and explored the local immune regulatory effects of Bangdeyun. The gestational mice were randomly divided into normal group, model group and Bangdeyun-treated group. EID models of mice were established by using indomethacin. The endometrial expression of NF-kappaB was detected by immunohistochemistry and Western blotting. IFN-gamma and IL-10 were measured by enzyme-linked immunosorbent assay (ELISA). The results showed that in the normal group, NF-kappaB and IFN-gamma were weakly expressed and IL-10 was strongly expressed in the endometrium during the whole implantation period. In the model group, the expressions of NF-kappaB and IFN-gamma were increased on pregnancy day 5, 6 and 7, and IL-10 expression decreased during the whole implantation time when compared with those in the normal group (P<0.01 for all). In the Bangdeyun-treated group, little amount of NF-kappaB and IFN-gamma was expressed and IL-10 expression was strong, much the way they were expressed in the normal group (P>0.05). The expressions of NF-kappaB and IFN-gamma were much lower in the Bangdeyun-treated group than those in the model group on pregnancy day 5, 6 and 7 (P<0.01 for all), while the expression of IL-10 was much higher than in the model group during the whole implantation time (P<0.01). It was suggested Bangderun may favor a shift from Th1- to Th2-type immune response, therefore inhibiting the maternal immune rejection, inducing the immune tolerance and improving the fetal implantation.

BACKGROUND: Child neglect is one of the most important aspects of child abuse and has become a serious problem influencing children's development all over the world. Therefore, it is necessary to nderstand the current conditions and influential factors of child neglect and establish effective evaluation methods in China.OBJECTIVE: To investigate the current conditions and influential factors of urban child neglect in Suzhou city.DESIGN: A comparative analysis of sampling survey.SETTING: Department of Children's Health Care, Soochow University Affiliated Children's Hospital.PARTICIPANTS: This study was conducted in one public kindergarten and two private kindergartens of urban areas in Suzhou city between March and October 2003. Totally 370 children (196 boys and 174 girls) aged between 4 to 6 years old without obvious physical and mental diseases were voluntarily investigated, and they had been living with the person that answered the questionnaire regarding to child neglect in China in the recent 1 year. METHODS: Questionnaire regarding to child neglect in China was sent to each volunteer.he questionnaire evaluates the current conditions of child neglect by 20 items of 5 aspects including physical care (buy fruit for child, consider the nutritional need of child, care about the body height and body mass of child), emotional care (chat with child, play and tour with child, encourage child to do the things whatever they can, listen to what the child feels, introduce the child to the guests when they come to your home, let him or her stop immediately when child cries, care about the activities in kindergarten), education care (buy books for child, tell stories to child, recognize and correct the bad behavior of child, answer the questions asked by child seriously), safety care (protections against fire and electricity at home, warn child against matches, knives and other sharp things, teach child how to cross the road) and health care (prepare the common medicine for child at home, urge child to brush teeth, correct the bad posture). The volunteers were asked to answer each question objectively according to the conditions of child within the recent 1 year, and each question should be answered by selecting only one choice (never, occasionally, usually, always), and anyone should not be omitted. Meanwhile,the educational background and occupation of the parents were also investigated.MAIN OUTCOME MEASURES: The general status of child neglect and the effects of different family educational background and occupation of parents on child neglect were observed. RESULTS: Totally 370 questionnaires were sent out, and 370 qualified ones were recollected, the effective rate was 100%. ① In Suzhou city, the children were given better regards and good care in the aspects of education, medicine and safety, but neglects on children's physical and mental care still exists in a few families. ② Families of different educational background could think highly of the medical care, safety and psychical care of children, but neglects on education and emotional development more commonly existed in the families with the educational background under university. ③ All the families with different occupation could think highly of the medical care, safety and physical care of the children, but education and emotional development were better in the cadre families than in the ordinary families.CONCLUSION: In Suzhou city, the children are given better regards and good care in the aspects of education, medicine and safety, but some bad manifestations of child neglect exist in education and emotion, which are associated with the educational background and occupation of the parents.Further studies about the evaluation, prevention and intervention are needed for child neglect in China.

Objective To evaluate the effect and safety of the intermittent deferoxamine therapy on relieving iron overload caused by transfusion in senile. Method Twenty-three senile with iron overload caused by transfusion were administered in a total daily dose of 20 - 50 mg/ ( kg·d ) for 5 - 6 days per week every 4 -6 weeks,the maximal dose was 2000 mg/d, add in 0.9％ sodium chloride 500 ml, continuous intravenous drip for 6 h. Result Nine months after therapy, serum ferritin fell from (2771.5±735.3)μg/L to (2483.7 ±724.4) μg/L (P＜0.01), and urine ferritin elevated from (9.68 ±5.39)μg/L to (12.14±5.50) μ g/L (P＜0.01 ). Conclusion It shows that intermittent deferoxamine therapy can reduce the serum ferritin with no significant toxicity.

Objective To observe the effects of extracts of ginkgo leaves (EGL) on acute myocardial infarction, acute myocardial ischemia and blood hemorheology.Methods The effects of EGL on acute myocardial infarction were observed in dogs model induced by the ligation of anterior descending branch of left coronary artery; effects on acute myocardial ischemia were observed on rats model caused by intravenous injection of pituitrin and effects on blood hemorheology were observed in rabbits. Results EGL significantly reduced the myocardial infarction area, decreased the activities of lactate dehydrogenase and creatine phosphokinase in dogs, reduced the elevation of ST segment of electrocardiogram in rats with myocardial ischemia and decreased whole blood viscosity and plasma viscosity in rabbits. Conclusion EGL has protective effect against myocardial ischemic injury and can improve the parameters of blood hemorheology in rabbits. Its mechanism may be concerned with the reduction of the myocardial infarction area and infarction degree and the relief of acute myocardial ischemia.

Objective To investigate the effects of low density lipoprotein receptor (LDLr) pathway on podocyte injury in diabetic nephropathy (DN) under inflammatory stress.Methods Male db/db mice and db/m mice were randomly divided into four groups (8 mice in each group):db/m group (control),casein injected db/m group (db/m + casein),db/db group (db/db),and casein injected db/db group (db/db + casein).An inflamed model of DN was established according to our previous study.24-hour urinary protein was measured every week.The plasma lipid profile was detected by clinical biochemistry assay.Podocyte changes were evaluated by electron microscope and immunofluorescent staining.Lipid accumulation in the kidney was evaluated by oil red O staining and intracellular cholesterol quantitative assay.The protein expression of Wilm's tumor-1 (WT-1),nephrin,α-smooth muscle actin (t-SMA),and molecules correlated with LDLr pathway were examined by immunohistochemical staining or Western blotting.The colocalized protein expression of LDLr with WT-1 was examined by immunofluorescent staining and laser confocal microscopy.Results There were no differences in plasma levels of LDL and HDL among four groups.Compared with db/db group,the db/db+ casein group showed markedly increased 24-hour urinary protein,more significant podocyte foot process effacement and podocyte damage,increased lipid droplet accumulation in kidneys,increased protein expressions of LDLr,SCAP and SREBP-2 in kidneys (all P ＜ 0.05).Interestingly,increased LDLr protein expression in kidneys of db/db mice was negatively correlated with decreased nephrin protein expression (r =-0.855,P ＜ 0.01) and positively correlated with increased α-SMA protein expression (r=0.768,P ＜ 0.01).Conclusions The disruption of LDLr pathway induced by inflammation contributes to podocyte injuries in diabetic nephropathy.

Objective To explore the clinical application and curative effect of iron removal treatment with week-therapy in chronic iron overload related to blood transfusion.Methods Twenty patients who were diagnosed as chronic iron overload were retrospectively studied.The amelioration of liver and pancreatic fanctions in patients with chronic iron overload treated with week-therapy of iron chelating agent through intravenous drip.Results The changes in the level of serum ferritin [2693.7±709.9) μg/L] were not significant after treatment at six months,hut the cilinical symptoms were relieved obviously.The levels of serum ferritin in patients after the treatment at twelve months were significantly different from the level before treated [(2083.7±714.4) μg/L vs (2771.5±725.2) μg/L,t =3.35,P ＜ 0.01],and the decreases were significant in sixteen patients.The liver functions in seven patients were improved and pancreatic functions were better in five patients.Conclusion The study suggests that iron removal treatment with week-therapy is effective for chronic iron overload,and improves the functions of damaged organs.
