Objective To explore the role of CD73 in Toxoplasma gondii (T. Gondii) infection; To verify the host cells absent with CD73 would have less infection and replication of T. Gondii. Methods CD73 knockout and wild-type mice were infected with 20 cysts of ME 49 by oral gavage. The survival rate, clinic symptoms, pathology in the gut, and cytokine production were investigated in infected mice. Macrophages and dendritic cells with CD73-/- and CD73+/+ were infected with RH-YFP. The infective rates, the number of intracellular RH-YFP in the host cells, and the replication of intracellular RH-YFP were detected in these two type cells. Results CD73 knockout mice had a higher survival rate and milder clinic presentation with less morphologies in the gut in the acute T. Gondii infection compared with wild-type mice. CD73-/- macrophages and dentritic cells had less T. Gondii infection, and less intracellular parasite number and replication compared with CD73+/+ macrophages and dentritic cells in vitro. Conclusions CD73 as a GPI-anchored surface protein of host cell might be involved in forming the parasite vacuole, and promote the parasite's attachment and invasion of host eeUs. Host cells absence with CD73 would be less infection and replication of T. Gondii, and relative resistant parasites infection.

Objective To examine the differentially expressed invasion-related genes in two anchorage-independent uterine cervical carcinoma cell lines derived from the same patient using a cDNA array. Methods Two human uterine cervical carcinoma subclonal cell lines CS03 and CS07 derived from a single donor line CS1213 were established by limited dilution procedure. The two cDNA samples retro-transcribed from total RNA derived from CS03 and CS07 cells were screened by a cDNA microarray carrying 234 human cell-cycle related genes and 1011 human signal transduction and membrane receptor -associated genes, scanned with a ScanArray 3000 laser scanner. Results The cDNA microarray analysis showed that 12 genes in CS03 were up-regulated compared to CS07, and 24 genes in CS07 were up-regulated. The function of a number of differentially expressed genes was consistently associated with cell-cycle, cell proliferation, migration, apoptosis, signal transduction and tumor metastasis, including p34cdc2, TSC22, plasminogen activator inhibitor I (PAI-1)and desmosome associated protein(Pinin). Conclusion Multiple genes are differentially expressed in uterine cervical carcinoma cell lines even came from the same patient. It is suggested that these genes are involved in the different phenotypic characteristics and development of cervical carcinoma.

BACKGROUND: Herbal wines are an important part of the traditional Chinese medicine. The traditional medicated wine, lishizhen herbal wine,which can strengthen the immune function, has long been used for some chronic diseases. But,its mechanism remains unclear.OBJECTIVE: To explore the immune pharmacodynamics of lishizhen herbal wine and to observe its effect on the immune organs (spleen,pancreas) and lymphocyte transformation rate in mice.DESIGN: A randomized controlled experiment based on the observation of the experimental animals.SETTING: Department of integrated traditional Chinese and western medicine and the department of pharmacology of a university hospital MATERIALS: The experiment was completed at the Central Laboratory of Zhongnain Hospital of Wuhan University from September 2000 to December 2000. A total of 90 healthy Kuming mice were involved in the study.METHODS: Different doses of the herbal wine,cartinellin and the same volume of distilled water were given to the experimental animals. The drug administration was orally injected directly to the stomach of the animals once a day and 10 days consecutively. One hour after the last administration,the animals were put to death. Then,the thymus gland and the spleen were taken out and weighed to calculate the indexes of the thymus gland and the spleen. In the last three days of the administration phytohemagglutinin(PHA)was injected intramuscularly at a dose of 10 mg/kg once per day. Two hours after the last administration, the tails of the mice were cut out, the blood samples were taken to perform the Wright' s staining,and 100 lymphocytes were counted under immersion and the transformation rate was calculated.MAIN OUTCOME MEASURES: Primary results: ① The effect on the immune organs of normal mice; ② The effect of PHA on stimulating the lymphocyte transformation in mice. Secondary results: ③ The death condition of the experimental animalsRESULTS: Different doses of the herbal wine increased the spleen index in different degrees. The effect of medium dose group was obvious[(3.71± 0.78) g/kg] (P <0.05),and the thymus gland index increased a little (P>0.05). The cartinellin in the positive control group increased the spleen index[(3.79±0.91 ) g/kg] and there was no impact on thymus gland index. The transformation rates of the lymphocytes of different groups were increased to a different degree and presented a good quantity-effect relationship,especially the group administered a large dose[(45±14)%] (P<0. 01).CONCLUSION: Lishizhen herbal wine has an effect of increasing cellular immune function.

Objective:To determine the relationship between injury risk and alcohol drinking. Methods:Totally 531 patients (age≥18 years) who were treated for the ifrst time and came to the emergency room within 6 h atfer the injury were included. hTe American National Institute of Health questionnaire was used to investigate the trauma type, intentional injury, drinking before the injury, drinking volume, and drinking history in the past years and so on. hTe case-crossover method was used to analyze the data and relationship between alcohol drinking and injury.Results:Compared with the non-drinkers, subjects who drank alcohol 6 h before the injury had a higher risk of intentional injury (OR=2.79, 95%CI: 1.61–4.84). Male, drunken, patients with positive alcohol test results were more likely to suffer from intentional injury. Compared with the non-drinkers, victims who drank alcohol 6 h before injury had a higher risk of injury in traffc accidents (OR=2.41, 95%CI: 1.29–4.51). Compared with the non-drinkers, subjects who drank alcohol 6 h before injury had a higher risk of injury (OR=11.86, 95%CI: 5.48–25.65). Subjects who drank more than 6 standard drinks of alcohol 6 h before injury had much higher risks than non-drinkers (OR=24.52, 95%CI: 5.84–102.86). Conclusion:Alcohol drinking before injury is associated with increased the risk of trauma, intentional injury and injury related to traffc accidents.

Objective To study the feature of neonatal infections and characteristics of antibiotic treatment in a tertiary children ' s hospital. Methods Clinical data including incidence of infection, primary disease,species of bacteria, complication and antibiotic utilization in hospitalized patients from Jan. 2010 to Dec. 2012 were retrospectively reviewed using their medical records. Results Among 1826 patients admitted to neonetal surgery ward, 542 infants ( 29. 7%) were with infection. The incidence of antibiotic resistance was 23. 51%. The top five infectious diseases were:perianal abscess, necrotizing enterocolitis, colicitis, omphalitis and subcutaneous gangrene. 12 cases of multi-resistant infection were cured by non-restricted antibiotics. 109 were cured by restricted antibiotics. And other 7 were cured by special antibiotics. No death nor multi-resistant nosocomial infection were found. Risk factors including multi-site infection, premature or low birth weight infants, liver, kidney or heart dysfunction,fever lasting more than 3 days after antibiotic therapy, septic shock, sepsis, digestive tract perforation and peritonitis,were vital in choosing specific antibiotics. Conclusions Infection is one of the most common diseases in neonatal surgery ward, with major pathogens sensitive to antibiotics. The clinical characteristics and drug sensitive test are conductive to the reasonable use of antibiotics. Special antibiotics can be used directly in patients with risk factors Clinical doses of antibiotics in neonates depend on the monitoring of drug concentration.
