ObjectiveTo observe the effect of digital auditory activation and touching intervention on infants with cerebral dysfunction.Methods388 infants with perinatal high-risk factors and abnormal result of Denver Development Screening Test (DDST) were randomly divided into group A (n=135), group B (n=128) and group C (n=125), and treated with digital auditory activation combined with touching (group A), simple touching (group B) and simple drug (group C) with 10 days as a course. All infants were tested with DDST after one therapeutic course, and tested again with DDST after the infants of group B and group C treated continuously for six therapeutic courses; and all infants were assessed with the Gesell development quotient (DQ) after six months.ResultsAfter one therapeutic course, normal rate of DDST was 71.11% in group A, 26.69% in group B and 20.00% in group C. After six therapeutic courses, that was 90.37 % in group A, 62.50 in group B and 40.00% in group C. After six months, the children with the Gesell DQ over 86 scores was 125 (92.60%) in group A, 90 (70.31%) in group B and 62 (49.60%) in group C. There were significant differences among three groups ( P<0.01).ConclusionThe digital auditory activation combined with touching has short therapeutic course and high efficacy, so it is a good therapeutic method for infants with cerebral dysfunction.

In this study, nattokinase gene was amplified by PCR using bacillus subtilis chromosomal DNA as template and cloned into expressed vector pBV220. After transforming recombinant plasmid into E.coli HB101, the recombinant strain was yielded. It was proved that expression products was secretive and expression protein was 12% of total cell protein by SDS-PAGE. Optimum culture time and inducing time was determined as 6h and 5h respectively. The plasmid stability studies showed that recombinant plasmid has excellent segregational stability but the structural stability was not good in the host cell.

Aim To ascertain whether defibrase has the protective effect against reperfusion injury after cerebral ischemia.Methods 70 renovascular hypertensive rats(RHR) were randomly divided into defibrase group, control group and sham-operated group.Reversible middle cerebral artery occlusion(MCAO) models were produced by the modified. Longa's method,and reperfusion was begun 2 hours after occlusion.Rats in the defibrase group were given defibrase 10 U?kg-1 body weight via femonal intraveneous injection, and in the control group with the same amount of saline. The brain pieces were processed by TTC and HE staining and the infarct size,brain microvessels damage and secondary bleeding were compared between the two groups. Results The volume of infarction in the defibrase group was obviously smaller than in the control group, the damage of brain microvessels was less severe, and the bleeding lesions under optical microscope were less than in the control group. Conclusion Defibrase has protective effect against reperfusion injury post cerebral ischemia.

Objective To evaluate the clinical significance of bladder saline perfusion before catheter removal in TURP patients. Methods From 2009 to 2011,140 patients received TURP were enrolled in this study.Patients were divided into perfusion group (70 cases with bladder saline perfusion before catheter removal) and control group (70 cases without perfusion). Results Comparing with the control group (33.1 ± 5.4) min,the time waiting for urination was shorter in perfusion group ( 3.7 ± 0.2 ) min ( P ＜0.05 ).The recovering time to normal urination was shorter in perfusion group (7.7 ± 1.2 ) d than in control group (11.7 ± 1.3) d (P ＜ 0.05 ) as well.In the first urine after catheter removal and first urine on the next day morning,white blood cell count of 2 groups (4.5 ± 0.1 ) vs ( 6.9 ± 3.5 ) ; ( 3.7 ± 0.2 ) vs (4.3 ±0.5) had significant differences ( P ＜ 0.05 ). Conclusion Bladder saline perfusion before catheter removal in TURP patients is simple and effective for the restoration of normal voiding.

Objective To discuss the clinical value of 99Tcm-sestamibi(99Tcm-MIBI) myocardial perfusion imaging on detecting myocardial ischemia in children with Kawasaki disease(KD) at convalescence period.Methods Twenty-one children wih KD at convalescence period were divided into 2 groups according to results of echocardiography.Four cases with coronary artery dilation,17 cases without coronary artery dilation.All cases accepted dipyridamole stress myocardial perfusion imaging.These patients who had positive results were given rest myocardial perfusion imaging again next day.Results Among 21 cases,9 cases(42.8%) were positive in perfusion imaging.Four cases with coronary artery dilation showed myocardial ischemia in different degree detected by myocardial perfusion imaging.Among 17 cases without coronary artery dilation,5 cases(29.4%) were positive.Conclusions Compared to echocardiography,99Tcm-MIBI myocardial perfusion imaging can objectively evaluate the location,extent and degree of myocardial ischemia of children with KD.It will be a routine test in observing its phase development.

BACKGROUND: Acute pulmonary embolism (APE) is a disorder involving the pulmonary circulation resulting from a blockage of the pulmonary artery. The present study aimed to investigate the effects of aspirin on the nuclear factor-κB (NF-κB) activity in a rat model of APE. METHODS: A total of 108 healthy male Sprague-Dawley rats were randomly assigned into six groups (n=18 rats per group): control group, sham operation group, APE model group, and low-, medium- and high-dose aspirin groups. Six, 24, and 72 hours after the induction of APE, rats in the low-, medium- and high-dose aspirin groups were given aspirin at a respective daily dose of 150, 300, and 600 mg/kg by gavage for three consecutive days. Rats in the other groups were treated with equal volumes of normal saline. Six rats in each group were anesthetized with 10％ chloral hydrate solution at each time point, and then the lung tissues were colected and analyzed using immunohistochemical staining. RESULTS: Positive immunohistochemical staining was present in the bronchial epithelial cells, alveolar cells, macrophages, and surrounding bronchial smooth muscle cells. When compared with the APE model group, the number of positive cells was significantly lower in the other groups at each time point (P<0.001). Statistically significant differences were also observed among the aspirin-treated groups at 6 hours (P<0.05,P<0.001). Compared with the APE model group, NF-κB protein expression was reduced in the other groups at each time point (P<0.05,P<0.001). Rats from the APE model group had thrombosis, damaged alveolar walls, and pulmonary hemorrhage, along with different degrees of infl ammatory cellular infiltration at each time point. However, pathological changes such as pulmonary hemorrhage and infiltration of inflammatory cells were attenuated after the aspirin treatment. CONCLUSION: Aspirin can significantly inhibit NF-κB activity in the lung of rats with APE in a dose-dependent manner, and can alleviate lung injury after APE.

AIMTo evaluate the joint action of phoxim and fenvalerate on the reproductive function in male Sprague-Dawley rats.

METHODSThe 2 x 2 factorial analysis experiment was used in the study. The pesticides were orally given at daily doses of phoxim (Pho) 8.2 mg/kg, fenvalerate (Fen) 3.3 mg/kg and Pho 8.2+Fen 3.3 mg/kg (Pho:Fen = 5:2), 5 days a week for 60 days. Sperm motility was measured with computer-assisted sperm motility analysis (CASA) and daily sperm production estimated. Immunoenzymatic method and electron microscopy were used to evaluate the serum testosterone and the testicular morphology, respectively.

RESULTSThere were significant decreases in sperm motility parameters in the treated animals, including straight line velocity (VSL), beat cross frequency (BCF), linearity (LIN) and straightness (STR). After treated with Fen, significant decreases in VSL, LIN and STR were demonstrated. Significant decreases of daily sperm production were seen in animals treated with Pho and Pho+Fen in comparison with the controls. Serum testosterone levels were not significantly changed in the treated groups. Factorial ANOVA showed that no significant interactions were noted between Pho and Fen in sperm motility, sperm production and serum testosterone. Both the single and mixed pesticides caused various degrees of testicular lesions, involving vacuolation of endoplasmic reticulum and necrosis of Sertoli cells.

CONCLUSIONThe pesticides may cause sperm motility changes and testicular lesions in male rats. The action of Pho and Fen may be additive.

OBJECTIVETo study the expression changes of tumor necrosis factor-alpha (TNF-(alpha), interleukin-6 (IL-6), C-reactive protein (CRP), monocyte chemotactic protein 1 (MCP-1), and their correlation with obesity in 20 -50 years old population of phlegm-damp constitution (PDC) and of normal constitution (NC) using Luminex technique.

METHODSTotally 101 population were recruited from Health Examination Center of Puren Hospital from April to December 2011. Based on body mass index (BMI), the subjects were assigned to four groups, i.e., the obesity of PDC group (Group OBT, BMI > or = 24 kg/m2, 30 cases), the non-obesity of PDC group (Group NOBT, BMI < 24 kg/m2, 25 cases), the obesity of non-PDC group (Group OBNT, BMI > or = 24 kg/m2, 28 cases), the NC group (Group P, BMI < 24 kg/m2, 18 cases). The BMI and body fat percent (FAT%) were compared among the 4 groups. Serum levels of TNF-alpha, IL-6, CRP, and MCP-1 were measured with Luminex technique.

RESULTSBMI was significantly higher in Group OBT and Group OBNT than in Group NOBT and Group P (all P < 0.05). The FAT% was significantly higher in Group OBT and Group OBNT than in Group P (P < 0.01). The serum TNF-alpha level in Group OBT was higher than in Group P (P < 0.01). The serum CRP and MCP-1 levels were significantly higher in Group OBT, NOBT, and OBNT than in Group P (P < 0.05, P < 0.01). The score for PDC was positively correlated with TNF-alpha, IL-6, and MCP-1 levels (P < 0.05).

CONCLUSIONSAbnormal higher levels of inflammatory factors exist in 20 -50 years old population of PDC. Chronic inflammation exists in population of PDC and obesity people.
