OBJECTIVE To discuss the occupational hazard factors and protection measures of Central Supply Unit.METHODS The occupational hazard factors in the Central Supply Unit were analyzed and some suggestion on the occupational protections to decrease occupational risk was done.RESULTS It is necessary to give some special training about the occupational safety,reinforce the precaution of occupational hazard with regard to biology,physics,chemistry and motor function to establish some protection and countermeasures.CONCLUSIONS The pertinent occupational protection strategy according to the actual hazard factors is more efficient and more benefit for high quality management of Central Supply Unit which will enhance the standardization,quality and working efficiency,and ensure the work safety and quality.

Periodical assessment over the actual situation of physician work in a Class One Grade A hospital in Beijing is performed, and some ideas to improve the work are proposed in view of the problems existing in the work.

Objective To investigate the nalaxone treating first acute right heart failure.Methods52 patients with FARHF were divided into the naloxone group(30cases)and control group(20cases)at random.Patients in control group were given general comprehensively treating.Patients in naloxone group were given naloxone as well as comprehensively treating,were given intravenously 0.8 mg of first dose,if it was necessary,repeated 0.8 mg of dose,and continuously dropped for 1.2 mg was added into liquid 500 mL.After treatment of 24 hours,were compared the changes of HR、SBP、SV and heart function.ResultsIn the naloxone group,the total effective rates were 84.4%,the mortality rates were 6.6%;in control group.The total effective rates were 60%,the mortality rates were 18.3%.The difference of the effective rate of the naloxone group be treatment was statistically significant(P

Objective To study the expression and clinical significance of proliferating cell nuclear antigen(PCNA) and PTEN in endometrial carcinoma.Methods The expression of PTEN and PCNA of 18 cases of proliferative endometrium(normal group),21 cases of atypical hyperplasia of endometrium(precancerous lesion group),and 22 cases of endometrial carcinoma(endometrial carcinoma group) was determined immunohistochemically(SP method).Results PCNA expression in the normal group(16.1%),precancerous lesion group(71.4%),and endometrial carcinoma group(95.5%) was significantly different(P

Objective To study the effect and safety of controlled-release dinoprostone on the induced labor of late pregnancy . Methods 60 cases of late pregnancy puerpera were treated in our hospital from February 2014 to September 2015, and divided into the control group and the experimental group with reference to the stochastic indicator method, 30 cases in each group. The control group were given induced labor by oxytocin, and the experimental group were given induced labor by controlled-release dinoprostone, Changes of Bishop score, effects of promoting cervical mature, induced labor situation, and adverse reaction were compared between two groups. Results After medication, the cervical Bishop score of the group (8.35±0.93) points were significantly higher than (6.64±0.72) of the control group (P<0.05). The total effective rate 96.67％(29/30) of promoting cervical mature in the experimental group was significantly higher than 80.00％ (24/30) of the control group (P<0.05). Medicine to clinical time (14.89±1.57)h and total labor time (6.94±1.52) h of the experimental group were significantly better than (21.48±2.35) h and (9.30±1.31) h of the control group (P<0.05). The rate of delivery by vagina of the experimental group 83.33％ (25/30) was significantly higher than 60.00％ (18/30) of the control group (P<0.05). There was no different on adverse reaction rate between two groups. Conclusion There was good effects of Controlled-release dinoprostone on the induced labor of later pregnancy, with high rate of delivery by vagina and better safety.

Objective To apply fluorescence-activated cell sorting (FACS) and magnetic activated cell sorting (MACS) in sorting natural killer (NK) cells from human peripheral blood. The efficiency of these two methods were compared so that the basic conditions for the further study on the lower proportion of peripheral blood cells could be created. Methods Twenty cases of normal peripheral blood and 3 cases of post-hematopoietic stem cell transplantation (post-HSCT) were collected and NK cell were sorted by FACS and MACS. Results Before sorting the normal peripheral blood, the proportion of the NK cell in the leukocyte was (12.86±3.62) %, the purity of NK cell was up to (96.15±2.03) % and the recovery was (95.08±2.16) %after sorting by FACS, the purity was up to (93.35±3.61) % and the recovery was (94.11±3.01) % by MACS.And before sorting the post-HSCT peripheral blood, the proportion of the NK cell in the leukocyte was (11.01±2.08) %, the purity of NK cell was up to (96.22±2.16) % and the recovery was (95.27±1.18) % after sorting by FACS. The purity was up to (90.98±1.94) % and the recovery was (94.54±3.52) % by MACS. Thereis difference in purity of NK cell (t = 5.925, P ＜0.05), while no difference in rate of recovery between 2methods (t = 0.789, P ＞0.05). Conclusion FACS is more efficient, rapidly and easily than MACS in sorting NK cell, especially for post-HSCT cases.

Diabetic retinopathy (DR) is one of the most common and serious diabetic complications, which is the main cause of vision loss in adults. The specific vascular and neuropathology mechanism of DR is not clear. It has been demonstrated that Inflammatory reaction might be take effects in the development and progression of DR. Monocyte chemoattractant protein-1 (MCP-1), as an important chemokine in the inflammatory response process, promotes chemotactic and activating factors, destroys the blood-retinal barrier, causes retinal vascular disease, and activates microglia, which is related to the severity of the disease. With further research on MCP-1, it is possible to use chemokines and their receptors as target cells to control or slow down the progression of DR by reducing or inhibiting the production of MCP-1 in diabetic patients in the early stages of the disease. This study can provide new ideas and new methods about preventing and treating DR.

Objective:To understand the current situation of human resources in the hemodialysis centers of different levels of hospitals in Beijing, and to provide reference data for themedical institutions at all levels to adjust the related human resources programs.Methods:Based on the self-designed questionnaire, the basic situation of 123 hemodialysis centers and the allocation of human resources of doctors, nurses and engineers in medical institutions of Beijing were investigated and analyzed.Results:Each nurse in hemodialysis center was responsible for (4.98± 0.74) hemodialysis patients at the same time in each treatment shift. The specialized nurses accounted for 23.32% of the total registered nurses. The ratio of engineers to dialysis machines was 1∶25.76. The proportion of doctors, nurses and engineers with intermediate professional titles or above was 82.47%, 33.08% and 29.81% respectively. The proportion of doctors with graduate education or above was 51.13%. The proportion of nurses and engineers with bachelor degree or above was 56.12% and 51.56% respectively. The differences in the professional titles and the highest academic qualifications of the employees (doctors, nurses and engineers) between tertiary hospitals and non-tertiary hospitals were statistically significant ( P < 0.05). Conclusion:The number of personnel in Beijing hemodialysis centers is basically in a similar proportion, but there are some differences between the hemodialysis centers of tertiary hospitals and those of non-tertiary hospitals in terms of age composition, working years, professional titles and educational background. It is necessary to optimize the allocation of human resources in hemodialysis centers of different levels of hospitals, further strengthen the training of professional talents and the cooperation of multidisciplinary teams, to promote the sustainable development of medical service quality.
