Objective:Mobile X-ray radiographic Units to appear in the clinical application of high voltage circuit judge special case of failure, the analysis in order to provide effective and reliable service basis. Methods: Preliminary judgment based fault location fault code, using stepwise exclusion analyze, judge, and determine the cause of the failure lies. Results:The high-voltage inverter element models of mobile DR, the driver circuit, the output voltage discharge waveform judgment and other issues have a better understanding, to facilitate the exclusion of equipment failure. Conclusion:Special case of X-ray radiographic Units failure high voltage circuit analysis and troubleshooting, especially for the inverter circuit analysis, X-ray radiographic appear to take timely and appropriate repair method when high pressure overload.

Ventilator is the mechanism of the implementation of artificial ventilation and its function is respiratory support, respiratory therapy and oxygenation improving. It is an important life-support equipment in life-saving first aid. Mainly for emergency transporters, recovery room, emergency department, the ICU pediatric, adult ICU and other departments in the hospital. It used to support high-risk, life-sustaining equipment. The failure is mainly concentrated on the two parts of the gas line and electric circuit. The daily maintenance and preventive maintenance are an essential part for protection breathing machine to work properly.

Objective To investigate the expressions of the CD13 in gastric cancer and the relationships between it and the patients' prognosis.Methods The expressions of CD13 were detected by immunohistochemical (SP method) in 104 cases of gastric cancer and 16 cases of normal gastric mucosa.Results The expressions of CD13 in 104 cases of gastric carcinoma and 16 cases of normal gastric mucosa show positive rate were 74％ (77/104) and 0％,respectively.The expressions of CD13 in gastric cancer were higher than in normal gastric mucosa and the difference was statistically significant (P ＜ 0.01).The expressions of CD13 in gastric cancer were not relative to patients' age,gender,and lymph node metastasis (P ＞ 0.05),but to be correlative with tumor sizes,clinical stage,degree of differentiation,and patients' 5-year survival rate (P ＜ 0.05).Conclusions The abnormal expression of CD13 in the gastric cancer may be correlative with the occurrence and development of gastric cancer,which can be an important indicator to evaluate the degree of malignance,guide treatment and assess uncertain prognosis of gastric cancer.

In traditional Chinese medicine,medical practice is combined with qi,which forms special qi-theory.Body fluid which includes blood and Jin-ye is the fluid structure of human being.Nutrient qi and defensive qi depend on these two kinds of body fluid.Defensive qi not only maintains physiological functions of Jin-ye,but also participates pathomechanism such as Jin-ye consumption,retention,etc.The identity of defensive qi and Jin-ye plays an important role in theory and clinic.

OBJECTIVE: To construct the data envelopment analysis (DEA) inference model for word-computing. METHODS: Firstly, a syndrome assembly was established based on the Chinese medical patterns contained in Shanghanlun, then the subjective evaluation was set by the linguistic description for the corresponding patterns. Secondly, with the data of decoctions, the evaluation was modified according to the requirement of DEA to construct the inference model. Finally, the word-computing was completed by the inference function of this model. RESULTS: DEA model could describe the diagnostic thinking process of Shanghanlun theory. CONCLUSION: DEA model can upload the information embodied among the words of the corresponding classical doses and symptoms, and it provides a kind of method for modernization of traditional Chinese medicine.

Objective To realize job satisfaction of doctors from the secondary hospital and its influencing factors and put forward countermeasures for doctor job satisfaction.Methods 2066 doctors from the secondary hospital were investigated by self-made scale,and analyzed by analysis of variance,non-conditional logistic regression analysis and other methods.Results The average score of total job satisfaction of doctors was (3.44±0.95),in which about 57.6% of doctors expressed satisfaction with the current work.The scale of job itself satisfaction had the hisheet score,that was (3.91±0.79),while the scale of job retum satisfaction had the lowest score,that was (2.85±1.16).Leadership behavior played the most decisive role in doctors job satisfaction(sβ=0.7,P<0.01).Condusion The total job satisfaction of secondary hospital doctors is just above the average and doctors are most dissatisfied with the work concentrated in the areas of return and the practice environment.

Objective To fabricate rabbit endothelial progenitor cells(EPCs)-seeded stents in vitro and evaluate its feasibility.Methods The mononuclear cells of rabbit were separated by density-gradient centrifugation using lymphocyte isolation.Cells were seeded on fibronectin-coated 6-well plates and maintained on M199 with endothelial cell growth supplements(ECGS,30 ?g/mL).After 2 weeks,cultured cells were identified by immunofluorescence and immunocytochemistry.EPCs proliferation and migration were measured by drawing a growth curve and modified Boyden chamber assay.EPCs adhesion assay was performed by replating EPCs on fibronectin-coated dishes.VEGF and G-CSF were assayed by ELISA while NO was tested by nitrate reductase method.EPCs were poured on fibronectin-coated or uncoated stents.After 6 days,scanning electron microscopy and fluorescence microscopy observation were performed.Results About 14 days after seeding,a majority of spindle-like cells appeared which were characterized as cells,double positive for Dil-acLDL and FITC-UEA-I.EPCs were further confirmed by its expression of the endothelial cell marks of vWF.After 2 weeks culture,EPCs proliferated in exponential growth.They showed high ability of adhesion(96.7?3.2%),migration(15?4) and could secret VEGF,G-CSF and NO.Compared with uncoated stents group,more EPCs migrated and adhered on fibronectin-coated stents group(27.80?4.26 vs 6.10?3.07cells/?400 field,P

AIM:The present study is to observe the effect of Danshen Tablet combined with Simvastatin on hepatic function in patients with hypercholesterolemia.METHODS:Patients with hypercholesterolemia were randomly divided into Simvastatin treatment group(n=20)and Danshen Tablet combined with Simvastatin treatment group(n=20).Before study and after 12 weeks treatment,serum lipid(TC,TG,LDL-C,HDL-C,AST,ALT and CPK)were measured.RESULTS:After treatment,serum lipid in both groups were improved significantly,and there was no difference between them.In Simvastatin treatment group,there was a tendency to increase in ALT and AST,but we could reject at the significant level.In the same way,the serum lipid in combination treatment group decreased,but no statistic difference.Compared with Simvastatin treatment group,ALT and AST in combination treatment group reduced significantly.CPK in both groups did not change.CONCLUSION:Danshen Tablet can reduce liver injury by statin and could serve as an adjuvant in clinical hypolipidemic treatment.

For probing into therapeutic effect, action, and proper and effective administration way of Jiang Ni Fu Sheng Liquid for treatment of acute cerebral hemorrhage, 150 cases were assigned at random to two groups to receive different therapies. Integral of hyponeuria, change of disturbance of consciousness, change of blood pressure, CT and clinical therapeutic effect were observed before and after treatment in the two groups. Results showed that the therapeutic effect in the treated group was obviously superior to that in the control group, with a markedly effective rate of 51. 1% and an effective rate of 90. 0%. It is suggested that Jiang Ni Fu Sheng Liquid has the action of relieving disturbance of consciousness, promoting recovery of nervous function, keeping stability of blood pressure, accelerating absorption of cerebral hemorrage, alleviating cerebral edema and hemorrhage of digestive tract, and so on.
