Objective:To discuss the bacteria detection before and after disinfection by using central negative pressure suction device terminal socket, reduce cross infection probability in hospitals and provide evidence for disinfection management specification. Methods:one hundred and thirty clinical central terminal devices with negative pressure were disinfected spirally with iodine swabs and among them, Department of respiration 48, Department of cerebral surgery 46, and Pediatrics 36, were sampled and sent to be cultured by clinical laboratory personnel before and after disinfection. The specimens were administered in a sterile blood AGAR plate culture medium, and the bacterial growth conditions were observed to detect the bacteria number as pollution standards. Results: The pollution rates of clinical equipment central pressure suction into the terminal socket after disinfection were: Department of respiration 8.33%; Department of cerebral surgery 6.52%; Pediatrics 5.56%, and the average pollution rate was 7.69%.The detected cases of pathogenic bacteria were gram-negative bacteria pollution, and contrasting the pollution rates before and after disinfection was statistically significant(x2=14.08, P<0.05). Conclusion: Using based iodine swabs disinfection central pressure suction mouth terminal socket can reduce the cross infection between the patients with risk and provide patients with safe medical environment.

Objective To observe the effect of enzymes-hydrolyzed wheat bran(EHWB) on antioxidant system in diabetic rats.Methods Diabetes mellitus models were induced by alloxan injection and EHWB was used to test its effect on anti-oxidative capacity;the EHWB was given intragastrically(i.g.),sodium ferulate(SF) as a positive group.The level of blood glucose,total anti-oxidative capacity(T-AOC),the activities of superoxide dismutase(SOD),glutathione peroxidase(GSH-Px),and xanthine oxidase(XOD),and the content of malondiadehyde(MDA) were detected respectively in serum and liver of rats.Results EHWB significantly decreased the level of blood glucose and increased the level of T-AOC,as well as the activities of GSH-Px and SOD,and decreased the activity of XOD and the content of MDA.However,there was no difference between the groups feeding SF and EHWB.Conclusion EHWB can be used to decrease blood glucose and improve antioxidant ability in diabetes mellitus rats,the effect of EHWB is similar to SF.The effect of decreasing blood glucose of EHWB is related to protecting liver.

To embark on a standard,systematic and legal metrology work in grassroots medical units,it is recommended that the position of a full-time gauger should be set and more effort should be put into publicity and supervision of metrology law,which is an indispensable part of equipment management.[Chinese Medical Equipment Journal,2008,29(2):108-109]

Objective To investigate the differences in clinical features between primary liver cancer (PLC) patients with positive and negative hepatitis B virus (HBV) and discuss the correlation of positive HBV and TNM staging.Methods Clinicopathological data of 430 patients with primary liver cancer who underwent partial hepatectomy in Henan Cancer Hospital from November 2012 to December 2015 were retrospectively reviewed.The cases were divided into HBV-positive PLC group (n =362) and HBV-negative PLC group (n =68) in according to the HBV infection status.x2 test was performed to analyze the clinical feature differences of the two groups.Spearman rank correlation was used to assess the differential clinical features and TNM staging of HBV-positive PLC.Results There were statistic differences in gender,age,AFP level,tumor numbers,tumor size,histopathological types and TNM staging between two groups (P ＜0.05).Furthermore,AFP level,tumor numbers,tumor size and histopathological types showed positive correlation with TNM staging (all P ＜ 0.05).Conclusions A number of remarked differences in clinical feature of gender,age,AFP level,tumor numbers,tumor size,histopathological types and TNM staging could be observed in HBV-positive PLC patients compared with HBV-negative patients.HBV-positive PLC patients may have positive correlations of AFP level,tumor numbers,tumor size,histopathological types and TNM staging.

Objective: To investigate the understanding of other' s mind in children with autism in Beijing.Method: The instrument of this study was experimental test story. Results: Children with autism could understand other person' s physical and social desire, and predict behavior of others in accordance with desires. They basically unerstood other' s positive and negative emotions. However, they had a special difficult in understanding other' s cognitive mental states such as false belief. Concluslon: It indicated that the development of understanding other' s mental state is much more gradual and complex. Understandding other' s false belief is not all or nothing. The difference in understanding other's false belief between children with autism is not absolute, but relative.

Objective To observe the influences of Siwu Decoction on perioperative hidden hemorrhage in senile patients with intertrochanteric fractures, and to supply evidence for Chinese medicine in treating the hidden hemorrhage of senile intertrochanteric fractures patients. Methods By following the inclusion and exclusion standard, 36 patients were admitted into the study. With reference to the medication of Chinese medicine, the patients were divided into treatment group and control group. All of the patients were given conventional anti-infection medicine, symptomatic treatment and dietary guidance. In addition, the treatment group took Siwu Decoction orally, 10 days constituting a period of treatment from the third day after surgery. Before and after treatment, we observed hemoglobin (Hb) level, hematocrit (Hct) and hidden blood loss (intraoperative and postoperative) . Results Hb level was increased and hidden blood loss was decreased in the treatment group ( P<0.05 compared with those before treatment) , but the changes were not obvious in the control group (P>0.05) . The improvement of Hb level and hidden blood loss in the treatment group was superior to that in the control group (P<0.05) . Conclusion Siwu De-coction can increase Hb and Hct levels in senile patients with intertrochanteric fractures, which results into the im-provement of perioperative hidden blood hemorrhage to some extent.

Objective To explore the application of transanal drainage tube in decompression of acute left- sided colorectum obstruction and its nursing.
