Infection and inflammatory response can induce the brain damage in neonate,but the mechanism involved in it has not been elucidated completely.Proposed mechanisms include inflammatory response,cytokine and free radical-mediated injury,and excitatory amino acids-induced injury.The activation of microglia and selective vulnerability of immature oligodendrocyte play an important role in the whole process.Recent researches show that the fetal inflammatory response and complex gene regulation are also involved in the infection-induced brain damage.

Objective To study the epidemiological features of the endemic arsenism in Hohhot of Inner Mongolia in 2004-2006 in order to get scientific evidence for the control and prevention. Methods The historical data in Huhhot revealed that 51 arsenic villages in 3 counties(Tumotezuo,Tuoketuo and Helingeer) were investigated. When arsenic content in drinking water was 0.05-0.15 mg/L,the situation of endemic arsenism was investigated in the households having high arsenic contents of water. When arsenic content in drinking water was greater than 0.15 mg/L,the survey was conducted to investigate arsenic patients with census. Census rate was not lower than 90%. Patients of endemic amenism were diagnosed by The Standard of Diagnosis for Endemic Arsenism (WS/T 211-2001). Results A total 28 083 people were examined,3978 were determined to be patients with arsenism,including 1722 being suspicious, 1897 mild,329 secondary and 30 severe. The total incidence of arsenism was 14.17% (3978/28 083),while the incidence of suspicious,mild,secondary and severe disease was 6.13% (1722/28 083) ,6.75% (1897/28 083),1.17% (329/28 083) and 0.11% (30/28 083),respectively. Suspicious and mild patients were most frequently seen. The incidence of dyspigmentation,pigmentation,ketatoses,both dyspigmentation and pigmentation and all of skin disorders was 8.65% (2428/28 083),3.19% (895/28 083),6.48% (1821/28 083),2.13%(598/28 083) and 0.94%(265/28 083),respectively. The most seen skin disorders were dyspigmentation and ketatoses. The disease mostly occurred in those aged over 40 years,the incidence was 89.52% (3561/3978). The incidence of male [15.08%(2209/14 644)]was more than that of female[13.16%(1769/13 439)].Conclusions Current condition of arsenism in Hohhot is mild,arsenic disease surveillance should keep going. Prevention and control needs to be reinforced in the future.

Ribavirin is a broad-spectrum antiviral agent and glycyrrhizin has activities of anti-inflammation, immunoregulation and anti-viral infections. To enhance antiviral efficacy and weaken side-effects of ribavirin, antiviral effects of the combination of glycyrrhizin and ribavirin were studied in the present study. Firstly, a mouse model of viral pneumonia was established by inoculation of influenza H1N1 virus. Protective effects of glycyrrhizin and ribavirin used alone or in combination against H1N1 virus infection in mice were evaluated based on the survival rate, lung index and virus titer in lungs of mice. Results showed that the combination of glycyrrhizin and ribavirin significantly inhibited the lung consolidation with a 36% inhibition ratio on the lung swell of infected mice. The combination of the two drugs exhibited synergetic effects on survival of infected mice. The combination of 50 mg · kg(-1) · d(-1) glycyrrhizin and 40 mg · kg(-1) · d(-1) ribavirin resulted a 100% protection for infected mice with a synergetic value of 36, which was significantly higher than the control group and each drug alone. This combination also resulted a significant drop of lung virus titer (P < 0.01), as well as inhibition on the production of proinflammatory cytokines IL-6 (P < 0.01), TNF-α (P < 0.01) and IL-1β (P < 0.05) induced by virus infection compared to the control. The treatment of ribavirin plus glycyrrhizin was more effective in influenza A infection in mice than either compound used alone, which suggested a potential clinical value of the combination of the two agents.

Objective To evaluate the neuroprotective effect and safety of neonatal hypoxic-ischemic encephalopathy(HIE)treated with recombinant human erythropoietin(rhEPO).Methods Fifty-three neonates with HIE were randomly divided into rhEPO treated group(n=29) with the dosage of 300 U/(kg?time),three times a week for 2 weeks and control group(n=24)without rhEPO.All supportive measures were same between 2 groups.Neurological scoring was evaluated at d3,d5 and d7 Neonatal behavioral neurological assessment(NBNA) was evaluated at d7,d14 and d28.The neurodevelopment quote was evaluated at age of 3 and 6 months.Blood pressure,liver and renal function,blood electrolytes and blood hemoglobin,platelet and reticular red blood cell count were monitored before and after treatment in all infants.Results The neurological scoring between two groups had no difference at d3.The significant difference was found at d7(P0.05).Conclusions Teraphy with rhEPO on neonatal HIE infants can promote neurological recovery,and there is no serious side effect with rhEPO treatment.

Objective To investigate the effects of Pulmicort Respules on the airway resistance and airway remodeling in rats with allergic asthma. Methods Thirty-two SD rats were randomly divided into blank control group,asthma model group,Pulmicort Respules group and normal saline control group,with 8 rats in each group.On the 14th day of allergization,rats were challenged by ovalbumin inhalation and were treated correspondingly.On the 28th day,airway resistance was determined,HE staining was conducted in lung tissues of each group,and airway remodeling related parameters were also measured. Results The airway resistance of Pulmicort Respules group was significant lower than that of blank control group,asthma model group and normal saline control group(P

Objective To explore the clinical manifestations of ultrasonography(US),99mTc-methoxyisobutylisonitrile(99mTc-MIBI),and 131I whole body scan(131I-WBS)of patients with differentiated thyroid carcinoma(DTC)and cervical lymph node metastasis.Methods A total of 117 cases received examinations of US and 99mTc-MIBI before uses of 131I and received 131I-WBS after 6 d of 131I treatment.Combined with serum thyroglobulin(Tg),131I-SPECT/CT,lymph node biopsy and clinical follow-up of patients,cervical lymph node metastases were identified.Results In 117 patients,the sensitivity of US,99mTc-MIBI and 131I-WBS were 76.5%,67.1% and 83.5%(P

AlM: To analyze personality traits in preoperative patients who undergolaser in situ keratomileusis ( LASlK) and to provide psychological basis for the selection of refractive surgery.
METHODS: Eligible patientswere seeking customized LASlK (group A n=53), conventional LASlK(group B n=75)and non-operation patients with ametropia (group C n=71 ) , who completed 16 personality factor questionnaires (16PF). Statistical analyses were performed with one-way ANOVA by SPSS11. 0 software package.
RESULTS: Compared to group C, patients in group A scored high on dominance and tension levels, and low on emotional stability level(P<0. 05), while patients in group B were more venturesome and more experimenting, but were less vigilant ( P<0. 05 ). Additionally, there were statistical differences between group A and group B on dominance, gallantry and vigilance respectively(P<0. 05). CONCLUSlON: The data indicates that personality profiles of LASlK patients with refractive error influence their decision for correction. Patients need suitable psychological assessment before surgery who actively chose customized LASlK seem to be more assertive and suspicious.

Objective:The aim of this study was to detect the P2X7 receptor (P2X7R) protein expression in pancreatic carcinoma and to analyze its association with clinicopathology features of pancreatic carcinoma.And furtherly to explore the effects and underlying mechanisms of P2X7R on invasion and migration of PANC-1 cell line.Methods:P2X7R expression was determined by immunohistochemistry in specimens of primary cancer and adjacent noncancerous tissues respectively,and analyzed the relationship between P2X7R expression and clinicopathology features of pancreatic carcinoma.The transwell assay and wound healing assay were used for investigating cell invasion and migration ability of PANC-1,and western blotting was performed to measure the expresions of MMP2 and MMP9.Results:P2X7R protein was highly expressed in both PANC-1 cell line and tumor tissue,and associated positively with the histological differentiation and lymph node staging.The active P2X7R could increase the cell migration and invasion ability of PANC-1 cell line through up-regulated MMP2 and MMP9.Conclusions:The overexpression of P2X7R plays crucial roles in the migration and invasion of pancreatic carcinoma,and may represent a novel molecular target in pancreatic carcinoma therapy.
