Objective To explore the feasibility of applying ATP bioluminescence technology to disinfection quality monitoring of the flexible endoscope.Methods Totally 30 flexible endoscopes used repeatedly from October 2014 to March 2015 were randomly selected,and had the disinfection quality monitored by ATP bioluminescence technology and bacterial culture method respectively.Parallel comparison was carried out to evaluate the feasibility of applying ATP bioluminescence technology to disinfection quality monitoring of the flexible endoscope.Results ATP bioluminescence technology showed that the qualification rate of the disinfection was 93.3％,and bacterial culture method found it was 96.7％.The two methods proved the outer surface of the endoscope had the disinfection acceptable while the biopsy hole and intracavity not.There was no significant correlation between the two methods while high consistency between the detection results by the two methods.Conclusion ATP bioluminescence technology can be used for preliminary screening in field,instant and daily monitoring of the medical flexible endoscope,which assists bacterial culture method in disinfection quality monitoring of the flexible endoscope.

Objective To observe the clinical efficacy of bloodletting and cupping at Fengchi (GB 20) plus acupuncture in treating peripheral facial paralysis in acute stage.Method Sixty patients with peripheral facial paralysis in acute stage (disease duration ≤7 d) were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened by bloodletting and cupping at Fengchi (GB 20) plus acupuncture, while the control group was treated with ordinary acupuncture. The two groups were treated once a day, 5 times a week, 2 weeks as a treatment course and 3 treatment courses in total. The House-Brackmann (H-B) facial nerve grading system was observed before and after the intervention, and the clinical efficacies in the two groups were compared. Result The total effective rate was 96.7% in the treatment group versus 93.3% in the control group, and the difference was not statistically significant (P>0.05). There were statistically significant differences in the H-B score between the two groups respectively after 2 and 3 treatment courses (P<0.05).Conclusion Bloodletting and cupping at Fengchi (GB 20) plus acupuncture is an effective approach in treating peripheral facial paralysis in acute stage.

Objective:To analyze the job preference of doctors at township health center ( THC) and provide references for formulating effective policy. Methods:238 cases of doctors were sampled from Shandong, Anhui and Shaanxi provinces. Using a discrete choice experiment, we analyzed the data with a conditional logit model. Results:The most important job attribution was salary, followed by education for children, permanent post, work location, training opportunity, and years before promotion. The OR value of the monthly income of 8 000 yuan is 7. 0 compared to 2 000 yuan. Doctors will pay 3 857 yuan and 3 294 yuan respectively for better education for children and perma-nent posts. Monthly income increasing to 8 000 yuan will reduce the quitting rate from 35% to 8%, and providing better education for children and permanent posts will reduce 5%. The permanent posts at township health center and non-permanent posts in county hospital have the same appeal to the doctor. Conclusion:When choosing a job, doc-tors at THCs valued salary the most. Improving the education level for children can be beneficial for attracting and re-taining doctors at THCs. A permanent post is more attractive to doctors than non-permanent posts at THCs.

Objective To prepare the Target-directed probe(Hab18-SPIO) and to test its phisichemical characteristics. Methods The McAb Target-directed probe(Hab18-SPIO) was prepared through hepatocellular carcinoma(HCC) McAb(Hab18) conjugated toSPIO using chemical method,while negative McAb probe(SED-SPIO) was also prepared using the same method.These agents weretested by high-performance liquid chromatography(HPLC) and electron microscope. Results The results of HPLC and electronmicroscope proved that Hab18 was conjugated SPIO effectively.The diameter of particles was between 50 and 70 nm.The binding rate of Hab18 was 97.5%. Conclusion The probe targeted to membrane-associated antigen of HCC(Hab18g) has been successfully prepared,which has novel physiochemical property.It is of great value in specific MR diagnosis of early HCCs.

Objective To improve the understanding of malignant triton tumor on imaging findings.Methods CT and MRI findings of rare malignant triton tumor in 3 cases confirmed histologically were analysed with review of the literatures.Results 3 tumors included prostatic malignant triton tumor with pulmonary metastatic tumors and neurofibromatosis-I in 1 case,left haunch malignant triton tumor in 1 case and right maxillary sinus malignant triton tumor with destruction of maxillary sinus paries in 1 case.The imaging appearances of tumors were the huge soft tissue mass which strongly suggested malignant tumors,high signal intensity on T2WI,circular septa inside the tumors with low signal intensity.Conclusion Although the qualitative diagnosis of malignant triton tumor depends on pathological examination,CT and MRI play a useful role in diagnosis and differential diagnosis of this tumors.

A outbreak of disease with symptoms of evisceration and skin ulteration led to mass mortality in sea cucumber Apostichopus japonicus cultivated in indoor ponds near the Dalian coast from December 2004 to April 2005. Spherical virus particles with a diameter of 75-200 nm were found in the cytoplasm of cells in the water-system, the alimentary canal and in the respiratory trees of the diseased and dying sea cucumber individuals by electron microscopic observation of ultrathin sections. Examination by negative stained samples revealed that all the diseased sea cucumbers were infected by the virus, while the healthly ones cultivated outside the contagious area were not. Two bacterial strains were also isolated from the diseased animals. When exposed to a medium containing the virus particles, regardless of whether the bacterial suspension was added,healthy sea cucumbers exhibited identical disease symptoms as the ones in the indoor ponds, and had a mortality of 90%-100%. However, when exposed to a medium in which there was only one of the two bacterial strains, 30%-80% of the sea cucumbers were infected and nearly 20% died. Negative staining showed that the viral particles were detected only in the bodies of the tested animals that were exposed to the viral medium. Histopathologically, the diseased sea cucumbers are characterized by karyopycnosis, and disintegration of the endoplasmic reticula and mitochondria in the epithelial cells in the water-system, the respiratory tree and the alimentary canal.

Purpose To evaluate the correlation among diffusion weighted imaging (DWI), tumor Cellularity and hypoxia-inducible factor-1α (HIF-1α) for the high and low grade astrocytoma. Materials and Methods DWI was applied with 33 patients with astrocytoma confirmed by pathology, and ADC value was measured. Tumor Cellularity was measured using Scion Image 4.0.3.2. The expression of HIF-1α was tested using immunohistochemisty. Results Mean ADC value was higher in the low grade astrocytoma than that in the high grade astrocytoma (t=7.300, P<0.001). The tumor Cellularity was higher in the high grade astrocytoma than that in the low grade astrocytoma (t=-3.845, P<0.01). HIF-1αexpression could be demonstrated in the low grade [(20.08±10.01)%] and high grade [(47.91±19.03)%] astrocytoma. The negative correlation was demonstrated between ADC value and HIF-1αand tumor Cellularity (r=-0.756,-0.617;P<0.001). The positive correlation was demonstrated between HIF-1αand tumor Cellularity (r=0.622, P<0.001). Conclusion ADC value can be used to discriminate the low and high grade astrocytoma, and the role of HIF-1αshould be further to study with enlarged sample.
