Objective To evaluate the effect of microinvasive puncturatio in therapy of hypertensive intracerebral hemorrhage. Methods In 112 cases of hypertensive intracerebral hemorrhage,with CT orientation, the appropriate length of YL-1 type of intracranial hematoma puncture needle was penetrated into the hematoma. Washing, drainage and Urokinase were applied. Results 21 patients died, 91 patients' consciousness and physical function got better in 1-5 days, and 2 patients were in a vegetable state. Conclusion In therapy of hypertensive intracerebral hemorrhage, microinvasive puncturation can improve efficiency of clinical treatment, recovery of nerve function and daily living of patients,with advantages of safety,convenience,cheaper costs and minimal trauma.

Objective:To explore the relationship between the expressions of MCM5 and E2F-1 with the genesis,clinicopathological parameters of gastric carcinoma.Methods:Immunohistochemistry SP method was used to detect the expressions of MCM5 and E2F-1 in gastric car- cinoma tissues of 57 cases and in normal gastric mucosa of 20 cases.The correlation between expressions of MCM5 and E2F-1 and clinicopathological parameters of gastric carcinoma was analysed. Results:The positive expression rate of MCM5 in cancer tissues was 71.9%(41/57),while in normal mucosa it was 0(0/20).The difference between the two groups was statistically significant (P0.05).The correlation between MCM5 and E2F-1 expressions in gastric carcinoma was highly significant positive(r=0.635,P=0.000).Conclusion: Overexpression of MCM5 and E2F-1 corelates with occurence and development of gastric carcinoma.MCM5 and E2F-1 may work in the early phase in carcinogenesis of gastric carcinoma.

Objective To study the bystander effects and associated mechanisms through irradiated conditioned medium(1CM). Methods Natural kilhr(NK) cells were obtained from peripheral blood samples. ICM irradiated with different doses of 60Coγ-rays was used for culturing K562 cell strain. The degree of injury of K562cells by activated NK cells was observed, as well as the apoptosis frequency of K562 cell was investigated. Results Severe injury was induced in K562 cells cultured in ICM than the control (sham-irradiated) as shown by increased sensitivity to NK cells (P < 0.05). The apoptosis frequency of K562 cell was increased significantly compared with the control cells (P < 0.05). Conclusions The bystander effect induced by irradiation is existent. ICM can trigger the bystander effect on K562 cell strains.

Objective To investigate the basic data of risk estimation of lung cancer among non-uranium miners in China.Methods 2836 workers from 24 mines in 9 provinces/regions were face-to-face interviewed to collect information including age at exposure,exposure duration,cigarette smoking among others.Results Age of the investigated non-uranium miners ranged from 17 to 72(36.9±8.0)years.The miners received low and poor education,3% of them were illiterate,58% with primary and middle school education,only 7% with junior college and higher education.Seventy-five percent of the uranium miners are migrant rural workers.Ethnic minority miners accoungted for 16% of all the investigated miners.Among the migrant rural workers age at initial exposure was estimated to be 29.6±8.0 years.By the time of the investigation,46.7% of the miners had worked in the mine for five years and longer,working years in the mine was 6.7±6.8 years with a median of 4.1years.3.4% of the non-uranium miners began the initial radon exposure in mines before their 18 years of old.17.5% of the investigated miners reported working more than 8 h every working day.Among the males,58.0% were current smokers with a median of 16 cigarettes per day.Age to begin the cigarette smoking was 20 years on average.Current smoking rate was age-dependent,the rate as high as 69.2% for the males aged 15-19 years.Current smoking rate was significantly statistically lower in coal mines than that in other mines,49.0% vs 62.5%.Compared with other miners,more frequent mechanical ventilations were reported by coal miners,Conclusions In China non-uranium mines,75% were migrant rural workers,by the time of the investigation about half of them had worked in the mines for at least five years.Non-uranium miners began their mining at 30 years on average,with a very small percentage of 3%,exposed to the mining radon before their 18 years.Current cigarette smoking rate in non-uranium male miners was the same as the general male population in China.

The pathogenic microorganism laboratory is the main workplace for the detection of pathogenic microorganisms, including bacterium and virus, or related samples, which plays an important supporting role in the prevention and control of infectious disease and the fight against biological terrorist attacks. Unified biosecurity standard and sound biosecurity standard system should be established for the laboratory experiment of pathogenic microorganisms.

Objective:
To investigate the daily learning time status of elementary school students and understand the implementation of Health Requirements of Daily Learning Time for Secondary and Elementary School Students (GB/T 17223-2012) in schools, so as to provide a reference for strengthening and improving school health and health education in the new era.
Methods:
A stratified cluster random sampling method was used to select 7 776 primary school students in Shandong Province, and a survey questionnaire was designed based on the Health Requirements for Dayily Learning Time for Secondary and Elementary School Students(GB/T 17223-2012) standard to investigate their daily learning arrangements, sleep and physical activities, and breaks between classes. Comparison of intergroup differences were used by Chi square test and Kruskal-Wallis H test.
Results:
About 55.88 % of primary school students for daily learning time met the standard. There was a statistically significant difference in the daily learning time achievement rate among primary school students in three grades for first and second grade, third and fourth grade and fifth and sixth grade ( Z=1 629.47, P <0.01), and the fifth and sixth grade had the highest proportion of achieving the standard (85.92%). Specifically, the proportions of students whose class hours, class numbers and morning reading time meeting the standards were 30.07%, 10.20% and 42.19%, respectively. The sleep deficiency rate of primary school studnets was 58.69%, and the physical activity deficiency rate was 65.78%; and there was a statistically significant difference in the rate of insufficient sleep time and physical activity time among primary school students of different grades ( χ 2=56.39, 95.95, P <0.01), with sixth grade students showing the highest rates for both sleep and physical activity deficiencies (64.35%, 73.37%). Additionally, 49.78% of students had recess time below the standard requirements.
Conclusion
The health status of daily learning time among primary school students in Shandong Province is poor, with insufficient implementation of school standards, and the implementation of standards needs to be further strengthened.
