OBJECTIVETo explore protective effects of acupuncture at "Zusanli" (ST 36) on cerebral tissue in rats with sepsis.

METHODSCecal ligation and puncture (CLP) was applied to duplicate the rat model of sepsis. According to random number table, thirty SD rats were divided into a sepsis model group (group A), a sepsis model plus electroacupuncture (EA) group (group B), and a sepsis model plus non-acupoint EA group (group C), ten rats in each one. EA with the same frequency and intensity at "Zusanli" (ST 36) and non-acupoint (0.5 cm laterally to "Zusanli") for 30 min was applied in the group B and group C, respectively. No treatment was given in the goup A. 6 hours after CLP, blood was acquired from abdominal aorta to measure the levels of neuron specific enolase (NSE). Then the rats were sacrificed by abdominal aorta exsanguination to take their cerebral tissue for measuring the levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6).

RESULTSSix hours after CLP, the level of NSE was (3.51 +/- 0.39) ng/mL in group B, which was significantly lower than (7.72 +/- 0.64) ng/mL in group A (P<0.05). The level of NSE was (8.02 +/- 0.72) ng/mL in the group C, which had no statistical significance with group A (P>0.05). The levels of TNF-alpha, IL-6 in cerebral tissue in group B were significantly lower than that of group A and C (all P>0.05).

CONCLUSIONEA at "Zusanli" (ST 36) has certain protective effect on septic rat's brain, which has some relationship with decreasing levels of cerebral tissue proinflammatory cytokine and plasma NSE. EA at non-acupoint has no the same action.

Objective To explore the effects of maternal cypermethrin exposure during lactation on testicle development and steroidogenesis of weaning offspring, and to provide a theoretical basis for the toxicity study of cypermethrin on reproduction.Methods Twenty-one healthy pregnant mice(clean animal) were randomly divided into three groups.Maternal mice were orally administered with different doses of cypermethrin [0,6.25 and 25 mg(/kg?d),10 ml/kg] dissolved in corn oil daily from postnatal day 1(PND1) to PND21.Fifteen male pups were randomly selected from each group and sacrificed at PND21 after exposure.The testicle organ coefficients were calculated.Serum testosterone(T) and estrogen(E2),testicle T were measured by radioimmunoassay(RIA).Histopathological changes in the testicle tissues were observed by HE stain.Testicle cells apoptosis was detected by TdT-mediated dUTP nick end labeling(TUNEL).Results A significant decrease was observed in body weight and the testicle organ coefficients in cypermethrin-treated group was in a dose-dependent manner(P0.05).Histological examination showed that maternal cypermethrin exposure markedly decreased the number and layers of spermatogenic cells,increased the inside diameter(ID) of seminiferous tubules,and disturbed the array of spermatogenic cells in testicle sections of pups at PND21.No significant effect on apoptosis of testicle cells was seen.Conclusion Maternal cypermethrin exposure during lactation may damage testicles and steroidogenesis of weaning offspring.

ObjectiveTo observe the clinical sense of clock-drawing test(CDT) and Mini Mental Status Examination(MMSE) in Alzheimer's disease(AD). MethodsMMSE and CDT were used to assess the intellectual ability in AD group and control group. ResultsThe orientation force, immediate memory, ability of calculation, short-term memory and speech ability in AD group were significantly decreased than that of the control group(P<0.05). The score of CDT in AD group was markedly suppression than that of control group(P<0.01). ConclusionThe CDT and MMSE are the ideal cognitive screening test to determine the degree in Alzheimer's disease.

Objective To explore the effect of Melatonin(MT) on CD4+CD25+ regulatory T cell (CD4+CD25+Tr)and airway inflammation in asthmatic rat.Methods Thirty-two SD rats were randomly divided into 4 groups,8 rats in each group.Asthmatic group:rats were immunized on day 1 and 7 by intraperitoneal inject of mixture of ovalbumin(OVA) and aluminumhydroxide.From day 14,the animals were allenged with aerosolized OVA for 20 min per day for 7 consecutive days.MT group:OVA-sensitized rats were injected intraperitoneally with 0.1 mg/kg MT 30 min before each OVA challenge.Dexamethasone group:OVA-sensitized rats were injected intraperitoneally with 0.5 mg/kg Dexamethasone 30 min before each OVA challenge.Control group:OVA for inhalation and MT for intraperitoneal injection was replaced with saline.After the last challenge,peripheral blood was stained to count the percentage of eosinophil(EOS).Then the rats were lavaged and total leukocytes counts in bronchoalveolar lavage fluid(BALF) were performed after staining with Wright-Giemsa staining.The EOS counts around the airway was counted after the histological section of lung staining with hematoxylin and eosin staining.The serum level of immunoglobulin E(IgE) was detected by immunoenhancement.The change of CD4+CD25+Tr was assessed with flow cytometry.SPSS 10.0 software was applied to analyze data. Results In asthmatic rats,the CD4+CD25+ Tr/ CD4+T cells ratio had significant negative relationship with the EOS counts around the airway and the total leukocytes counts in BALF (r=-0.73 P0.05).There was a significant decrease in the percentage of the eosinophils in peripheral blood,the eosinophil counts around the airway,the total leukocytes counts in BALF and the serum level of IgE in MT group compared with asthmatic group (Pa

Food allergies, as a type of adverse immune-mediated reactions to ingested food proteins, have become a serious public health issue that harms children and adults health, with increasing incidence year by year. However, without effective therapy for food allergies, doctors-have mostly advised to avoid allergens and provided symptomatic treatment. According to the findings of many studies, allergic diseases are correlated with intestinal barrier function injury, as evidenced by the significant increase in the intestinal permeability among patients with food allergies. In this paper, recent studies on correlations between food allergies and intestinal barrier functions, intestinal barrier function injury mechanisms of allergic foods and food allergy intervention strategies based on intestinal barrier functions were summarized to provide reference for laboratory researches and clinical treatment of food allergic diseases.

OBJECTIVEAtopic dermatitis affects children's behavioral, emotional and psychological development. This study aimed to investigate the quality of life in infants with atopic dermatitis.

METHODSThe quality of life in 43 children with atopic dermatitis between the age of 3-6 months was assessed by the Childhood Atopic Dermatitis Impact Scale (CADIS). The severity of atopic dermatitis was determined by the SCORing Atopic Dermatitis (SCOARD).

RESULTSThe scores of SCORAD and CADIS in children with atopic dermatitis were 56.9+/-11.1 and 38.0+/-7.9 respectively. There was a positive correlation between the CADIS and SCORAD scores (rho=0.934, P<0.05). The CADIS score was positively correlated with the area of skin lesions (rho=0.581, P<0.01), erythema (rho=0.417, P<0.01), excoriations (rho=0.579, P<0.01), edema/exanthema papulosum (rho=0.595, P<0.01), oozing/crusts (rho=0.436, P<0.01), skin dryness (rho=0.343, P<0.01), pruritus and sleeplessness (rho=0.344, P<0.05).

CONCLUSIONSAtopic dermatitis adversely affects the quality of life in children with atopic dermatitis. The worse quality of life is associated with more severe atopic dermatitis.
