Objective: The purpose of this research is to investigate the relationship between computer game addiction,a subtype of internet addiction,and parental Rearing styles.Methods: Using Computer Game Addiction Inventory(CGAI) and EMBU,we investigate a sample of 747 senior high school students in Beijing.According to whether participants' sum score of five dimensions of CGAI is larger than 1.5 SD,we divide them into two groups: tendency to addiction and non-tendency to addiction.Then we analyze the data with methods of MANOVA and Canonical Correlation.Results: There is significant difference in sex distributing between tendency to addiction and non-tendency to addiction.There is also significant difference in parental rearing styles between two groups.Under authoritarian rearing styles,children score higher on nearly every dimension of CGAI.Conclusion: Boys are more likely to get addicted to computer games than girls.Negative parental rearing styles associate closely with computer game addiction.

Objective To perform the serological identification of anti‐E and anti‐Mur found in the detection before blood trans‐fusion and to analyze its clinical significance in blood transfusion .Methods The reaction pattern of serum with the antibody screen‐ing spectrum was detected by using the micro‐column gel method for identifying the antibody type and specificity .Results The 3 kinds of antibody anti‐E IgG combined with anti‐Mur IgG + IgM existed in the serum of 2 patients .Conclusion Anti‐E and anti‐Mur all are easier to lead to the hemolytic blood transfusion reaction .Selecting the suitable donor on the basis of the accurate anti‐body identification can provide guarantee for blood transfusion safety .

Objective To evaluate the application of Erytra automatic blood analyzer (Erytra) on blood grouping and cross matc‐hing .Methods 9 860 cases of EDTA‐K2 anticoagulant specimens for blood grouping test and 5 099 cases of EDTA‐K2 anticoagu‐lant specimens for cross matching were both detected by Erytra and manual tube method .Results There was no significant differ‐ence in the accuracy of blood grouping detected by Erytra and manual tube method (P>0 .05) .Both of the positive rate and the false positive rate of cross matching detected by Erytra were higher than those detected by manual tube method .Conclusion Erytra automatic blood analyzer can be applied for the detection of blood grouping and cross matching ,and its performance can meet the needs of blood safety in clinic .

[Objective]To investigate the biomechanical properties of transpedicular impacted grafting(TPIG) after bone loss calculation in the treatment of thoracolumbar compression fracture.[Method]Six fresh human thoracolumbar spine(T12-L2) specimens were tested as 6 models: normal control(group A),compression fracture(group B),TPIG after bone loss calculation(group C),transpedicular grafting(TPG)(group D),TPIG after bone loss calculation + pedicle fixation(group E),TPG + pedicle fixation(group F).Biomechanical analysis was carried out to test the intensity,stiffness,stability and torsion properties between different groups.[Result]The intensity,stiffness and stability of vertebral body and intervertebral disc in group E were higher than those in group F,with significant difference(P

Objective The purpose of this study was to examine the status quo of the perceptions of professional benefits in the clinical teachers of nursing,analyze the influencing factors and put forward effective measures to improve it.Methods A convenience sample of 117 nurse preceptors in 4 teaching hospitals participated by completing a two-part questionnaire the Preceptor's Perception of Benefits and Rewards Scale and a demographic questionnaire.Results The total average score of benefits and rewards to the preceptor role was(63.64±9.93) points,low than the study done by Hyrkas(2007) in American.Nurse preceptors in different nursing unit felt different benefits and rewards to the preceptor role.Medicine unit and surgical unit were higher than Pediatrics unit.The longer time of being preceptor,the higher score of benefits and rewards to the preceptor role.Conclusions The score of benefits and rewards to the preceptor role is low.Hospitals should increase support for clinical teaching program,particularly pediatrics.Nurse managers should adjust promotion opportunities,workload,rewards of nurse preceptors to meet the needs of nurses in clinical teaching and to improve teaching effectiveness.

Objective To observe the clinical efficacy of midnight-noon ebb-flow needling based on individualized timing in treating senile chronic gastritis. Method Seventy-eight elderly patients with chronic gastritis were randomized into a treatment group of 39 cases and a control group of 39 cases. The treatment group was intervened by midnight-noon ebb-flow needling based on individualized timing, while the control group was by midnight-noon ebb-flow needling based on local mean solar time, 10 d as a treatment course. The clinical efficacies were observed after 2 treatment courses. Result The total effective rate was 94.9% in the treatment group versus 89.7% in the control group, and the difference was statistically insignificant (P>0.05); the recovery rates were respectively 46.2% and 28.2%, and the difference was statistically significant (P<0.05). Conclusion Midnight-noon ebb-flow needling based on individualized timing can produce a significant efficacy in treating senile chronic gastritis, and is worth promoting in clinic.

Objective To explore the correlation between the length of peristaltic break (LPB) and the severity of the symptoms in patients with non-erosive reflux disease (NERD) and negative pH monitoring.Methods A total of 35 patients with NERD and negative pH monitoring were enrolled,and at same time 10 healthy individuals were selected as controls.The LPB of esophageal body of both groups was measured by high resolution manometry (HRM).Meanwhile,the symptom of NERD patients with negative pH monitoring was scored.The LPB of esophageal body between the two groups was compared by t test.The correlation between the LPB and the severity of the symptoms in NERD patients with negative pH monitoring was analyzed by Pearson correlation analysis.Results The average LPB of esophageal body of NERD patients with negative pH monitoring was (3.3±0.9)cm,which was longer than that of healthy controls ((1.2 ± 0.4) cm),and the difference was statistically significant (t=9.17,P＜0.01).The symptom score of NERD patients with negative pH monitoring was 21.6± 7.8.There was a positive correlation between the LPB and NERD symptom score (r=0.894,P＜ 0.01).Conclusion The LPB of esophageal body is a kind of expression of esophageal motility dysfunction,which is correlated with the symptom of NERD.

The potency and safety of thyroid artery embolization by Pingyangmycin Lipiodol Emulsion(PLE) were observed. The results suggested that PLE is a potential embolization agent in interventional therapy of hyperthyroidism with relative safety and efficacy.

Objective To investigate the sleep quality state of people who did physical examination,and its correlation with brachial-ankle Pulse Wave Velocity (baPWV).Methods The indexes of Pittsburgh sleep quality index (PSQI) and baPWV were used.The people who did physical examination were divided into sleep disorders group (284 cases) and normal sleep group (608 cases) according to the results of PSQI survey.Results (1) There were 31.84％ of the people who had sleep quality problems.(2) The PSQI total score and the score of subjective sleep quality (SSQ),sleep duration (Sdu),daytime dysfunction (DD) of females were higher than males (t =6.71,3.46,2.45,3.96,P ＜0.05).The PSQI total score and the score of sleep latency (SL),habitual sleep efficiency (HSE),use of sleeping medication (USM) among different age groups were statistically analyzed (F =12.23,8.31,7.50,7.11,P ＜ 0.05).(3) The score of baPWV of sleep disorders group was higher than normal sleep group (t =5.14,P ＜ 0.05).There were significantly positive correlation between baPWV and total PSQI score,subjective sleep quality,sleep time,daytime dysfunction (r =0.28,0.45,0.30,0.36,0.35,P ＜ 0.05).Conclusions 1/3 of the physical examination people have sleep quality problems.Sleep quality of females is worse than males.There are different styles among different age groups.There is significantly positive correlation between sleep quality and baPWV.
