Since the oral rehydration salts solution(ORS) has been used to treat acute diarrhea of children, there are different kinds of ORS in order to satisfy the need of clinical work. They are the initial WHO-ORS, other substances-supplemented ORS and the reduced osmolarity ORS, each of which has their own efficiency and advantage.

Objective To investigate the association of serum ferritin and hemoglobin with the pathogenesis of primary restless legs syndrome(RLS). Methods Thirty-five patients with primary restless legs syndrome and twenty insomnia controls were included in this study. The level of serum ferritin and hemoglobin were measured, and the data have been analyzed using t-test. Results The level of serum ferritin in the primary RLS patients (89.77μg/L (SD:48.52)) was significantly lower than in the contruls (123.36 μg/L (SD:35.06)) (t=-2.713,P <0.01), whereas the level of hemoglobin have no statistical difference between the RLS group (142.77 g/L (SD: 11.79)) and the control group (139.05 g/L (SD: 12.33)) (t = 1.108, P > 0.05). Conclu-sions The decrease of serum ferritin may be a risk factor of primary restless legs syndrome, but the level of hemo-globin is not associated with primary restless legs syndrome.

Objective To investigate couple's personality similarity effect on the marital quality,and to explore the vairance of such effect under different levels of spouse's depression. Methods The cross?sectional da?ta of 4644 couple from the national survey of mental health database in china( 2009) was used. Couples completed Locke ?Wallance marital adjustment test,The CES?D scale a self?report depression scale and Eysenck personality questionnaire short scale for Chinese version (EPQ?RSC). Results The personality similarities of couples(0.44 ±0.27) and their marital quality (wife (103.71±27.54),husband (106.15±26.94))had significant positive corre?lation ( r=0.25~0.27, P<0.01). Regression analysis showed the effect of personality similarity on the marital quality were varied according to the level of spouse depression( β=0.09?0.22, P<0.05) . Among participants whose husband or wife had higher level of depression,couple's personality similarity had stronger effect on his/her per?ceived marital quality. Conclusion Husband and wife personality similarity is related to marital quality signifi?cantly,and the spouse depression plays a significant moderating role in this relationship.

Objective To explore the change of serum level of neuron specific enolase (NSE) in neonates with asphyxia before and after head mild hypothermia.Methods Eighty-two asphyxial neonates were selected,including 39 mild asphyxial neonates and 43 severe asphy-xial neonates,and 29 healthy neonates were selected as control group.Forty-three severe asphyxial neonates were randomly assigned into mild hypothermia treatment group and traditional treatment group.Neonates in traditional treatment group were just given traditional treatment.While neonates in mild hypothermia treatment group received head mild hypothermia therapy and their nasopharyngeal temperature were maintained at(34.0 ? 0.5) ℃ for 72 h.Before treatment and 72 h after treatment,2 mL blood was collected,and the serum NSE was determined by radio immunoassay.Results NSE levels in mild asphyxial neonates group[(34.83?6.17) ?g/L] and severe asphyxial group[(59.58?8.87) ?g/L] were significantly higher than that of control group[(30.57?4.88) ?g/L](t=3.07 P0.05).The level of NSE at 72 h in severe asphyxial neonates with head mild hypothermia therapy[(40.97?6.55) ?g/L] was significantly lower than that of traditional treatment group [(48.15?5.57) ?g/L](t=3.86 P

Objective To investigate the effect of plasmid pEGFP- hepatocyte growth factor (HGF)-C1 on rat acute ischemia of hindlimb.Methods The eukaryotic expressed plasmid pEGFPHGF-C1 carrying human HGF cDNA was constructed.The transfection efficiency and the expression level of HGF were evaluated by transfecting pEGFP-HGF-C1 into primary rat skeletal muscle cells.Ligation-induced ischemia of femoral artery of one hindlimb in Wistar rats was performed.The plasmids (200 μg/500 μl) were injected once directly into the ischemic limb muscle (5 sites around ligation position) immediately after ligation.HGF expression was detected in the muscle tissue of rats on days 3,6 and 9 by immunochemical stain and Western blot.At day 24,the muscles were removed and stained with CD31 to assess histologically the capillary formation.Results The primary rat skeletal muscle cells could be transfected 0efficiently with pEGFP-HGF-C1 using LipofectamineTM2000 (0.8％),and secreted HGF which peak concentration was (5402.0±227.9) ng/L at 4 d.HGF expression was detected clearly in muscle tissue on days 3,6,9 in pEGFP-HGF-C1 groups.Western blot semi-quantitied analysis showed the levels of HGF expression were higher than control groups on days 3,6,9(P＜0.05).A significant increase in capillary density was found in rats transfected with human HGF(10.81±2.35) as compared with sham group (6.11±0.90) and control group (5.45±0.90) at 24 d(P＜0.01).Conclusions Intramuscular injection of naked human HGF plasmid may induce therapeutic angiogenesis in rat ischemic hindlimb models,as potential therapy for peripheral arterial disease.

Objectives To understand the effect of intraperitoneal injection of naringenin,a SMAD3 inhibitor,on the skeletal muscle after acute contusion in a mouse model.Methods Seventy-two mice of 7-8 weeks old (20-24 g)were randomly divided into a control group,an acute contusion (B)group,an acute contusion+1％DMSO injection (C)group and an acute contusion+naringenin injection (D)group,each of 18.The acute contusion model was created by hitting the right tibialis anterior muscle in mice of all groups except the control group.Intraperitoneal injection of I％DMSO and naringenin were given to group C and D respectively every day until execution,while the 18 mice in the control group were fed without injury or injection.The time of injury was set as Day 0.After being fed for 28 days,all mice were executed and the right tibialis anterior was harvested.Western blotting was used to detect the difference of SMAD3,pSMAD3,Collagen Ⅰ,and α-SMA expression among the 3 groups.Hematoxylin-Eosin (HE)staining and Masson staining were used to detect the difference of pathological changes.Moreover,the appearance of fast twitch contraction and tetanic contraction were also documented to figure out the quality of the injured skeletal muscle.Results Compared with the control group,the SMAD3 and pSMAD3 level in injured skeletal muscle increased,but both were less in group D than group B and C.Similarly,the average level of Collagen Ⅰ and α-SMA in all three injury groups was higher than the control group,but the level of these indexes were lower in group D than that in group B and C.HE staining showed more mesenchyme in injury groups than the control group.Masson staining found the upregulation of fibrosis in injured muscles,with the area of fibrosis in group D significantly lower than group B and C.Compared with control,the injured skeletal muscle had significantly poorer fast twitch and tetanic contraction performance,with the condition of group D significantly better than group B and C.Conculsion The naringenin,a SMAD3 inhibitor,mitigates the phosphorylation of SMAD3 after acute contusion in a mouse model.The fibrosis and scar formation was alleviated,hence improving the healing of the injured skeletal muscles.

BACKGROUND: Progressive body mass losses and physical strength decrease are common complications of malignant tumors, and they are important factors that affect the quality of life of the patients.OBJECTIVE: To probe into the curative effect of a Chinese herbal compound Yiqi Xiaozheng granules combined with antitumor drugs in the treatment of malignant tumors and its effect on the quality of life.DESIGN: A randomized controlled observation.SETTING:Clinical Tumor College of Peking University.PARTICIPANT: Totally 61 patients with malignant pulmonary carcinoma,breast or intestinal carcinoma hospitalized in the Wards of Integrated Traditional Chinese and Western Medicine of Beijing Cancer Hospital from June 1999 to March 2002 were recruited.METHODS: Altogether 61 cases of malignant tumor were randomized into the treatment group (treated with Chinese herbal compound Yiqi Xiaozheng granules supplemented with chemotherapy)(n=34) and the control group (treated with only chemotherapy was used)(n=27). The difference in curative effect, survival period with tumor and the quality of life of the two groups were observed. The comparison of the curative effects of the two groups was performed according to Clinical Curative Effect Criteria for Solid Tumors stipulated by World Health Organization: completely response, partly response, stable disease, and progressive disease. X-ray examination was performed on the patients before the therapy and two courses of treatment after the therapy to evaluate the curative effect. Physical strength grading was made according to the evaluation criteria of Eastern Oneology Cooperative Group of the United States. The two groups were graded before and after the treatment. The group with decreased grade after the treatment was considered to be improving, but the group with increased grade after the treatment was considered to be worsening.symptom before and after therapyparison of the curative effect of the two groups: The cure rate of the treatment group was higher than that of the control group (partial response rate,stability rate and progression rate of the two groups was 36% ,7% ;52%,survival with tumors: The mean period of survival with tumors of the treatment group was longer than that of the control group until March 2002ing: Physical strength grading status was better after the therapy in the treatment group than that in the control group [ In the treatment group, 9cases (26%)were ameliorated, 25 (74%)appeared stable , none was aggravated; in the control group, 1 case (4%) was ameliorated, 25(93%) appeared of qi-deficiency symptoms in traditional Chinese medicine before and after the treatment between the two groups. Symptoms such as sweating and qi deficiency manifested as disclination to talk, listlessness, debility, etc. were significantly reduced in the treatment group (The numbers of cases before and after the treatment were 20, 9; 17,9; 20,13 respectively). In the control group, the cases either were stable or showed an increase in symptoms (There were 13, 13; 14, 17; 18, 20 respectively before and after treatment).CONCLUSION: Compared with the control group, in the treatment of malignant tumors, Yiqi Xiaozheng granules supplemented with chemotherapy not only enhanced curative effect, but also improved the quality of life and prolonged the period of survival with tumors.

The objective of the present study was to establish a novel rapid fluorescence focus inhibition test (RFFIT GFP)for the detection of rabies virus antibody, in which a chimeric rabies virus expressing green fluorescent protein (HEP GFP) was used as the basic virus strain in RFFIT GFP assay, and a few serum samples from human, dog and cat were detected by this new method .The optimal serum dilution, virus dosage and infection time were determined in 24 serum samples from human, dog and cat by using RFFIT GFP, RFFIT and ELISA assays. The result showed that these 3 methods gave a good consistency. But RFFIT GFP was found to be more convenient and economic for the detection of rabies virus antibody.

Objective To investigate the relationship between the genesis of hypertensive disorder complicating pregnancy and neurokinin B (NKB).Methods The serum NKB levels of 229 women including non-pregnant women (n = 62),normal pregnant women (n = 80) and pregnant women with preeclampsia (n=37) or gestational hypertension (n= 50) were examined by enzyme linked immunosorbent assay.The umbilical blood levels of NKB and the NKB mRNA expression in the pregnant women were also tested by fluorescent quantitative reverse transcription-polymerase chain reaction technique.ANOVA and paired t-test were applied.Results (1)The maternal plasma NKB levels of normal pregnant women,patients with gestational hypertension or preeclampsia were significantly higher than that of non-pregnant women,respectively [(28.2±6.6)μg/L,(31.5±5.2)μg/L,(70.5±8.9)μg/L vs(3.2±1.8)μg/L,P＜ 0.01].In preeclampsia,gestational hypertension and normal pregnancy group,the NKB level in umbilical blood [(121.4±9.3)μg/L,(60.5±7.2)μg/L,(40.8±6.3)μg/L] were significantly higher than that of maternal plasma(P＜0.01).(2) The maternal plasma NKB level in gestational hypertension group was higher than that in normal pregnancy group,while the difference had no statistical significance (P＞0.05).The maternal plasma NKB level in preeclampsia group was higher than that in gestational hypertension group and normal pregnancy group (P＜0.01).Forty-eight hours after delivery,the maternal plasma NKB levels significantly decreased in the normal pregnant,gestational hypertension and preeclampsia group [ (14.1±4.2) μg/L,(16.4±3.8) μg/L,(25.4±5.2) μg/L],compared to the values before delivery (P＜0.01).(3) The expression of NKB mRNA in placenta of preeclampsia group was significantly higher than that of gestational hypertension group and normal pregnancy group [(3.8±0.6) × 10-3 vs(1.7±0.4) × 10-3 and (1.6±0.3) × 10-3,P＜0.01].No statistical difference was found in the expression of NKB mRNA in placenta between gestational hypertension group and normal pregnancy group (P＞0.05).Conclusions Elevated NKB level in placenta and maternal or umbilical blood might play an important role in the development of hypertensive disorder complicating pregnancy.
