Hospital Administrative Moral Standard has effects of guide, encouragement, harmonization and rectification. Administration should reflect principles of respect, justice and benefit. It should connect unith the purpose and the way of setting up the hospital, with the aim of educating health staff. The institution of the standard should combine administrative power with its function. The nucleus is to rectify opinion, action, discipline and attitude of the health staff.

Objective To observe and analysis the features of images of fundus fluorescein angriography (FFA) in low-perfused retinopathy caused by cephalo-cervical peripheral vascular stenosis or occlusion. Methods The results of FFA of 27 patients diagnosed with carotid artery stenosis or occlusion by digital subtraction angiography (DSA) and examination of Doppler and vascular-pulsation were retrospectively analyzed. Result All of the patients had a delayed arm-retinal circulation duration from 20.0 to 81.08 seconds with the mean of 32.1 seconds; a delayed retinal arteriovenous filling duration from 6 to 64.0 seconds with the mean of 24.2 seconds. Delayed arm-retinal circulation duration and retinal arteriovenous filling duration in 10 cases (37.0%); microangioma, vascular wall staining, nonperfused capillary area in 11 (40.7%); and anterior ischemic syndrome in 6 (22.2%) were found. In the 6 patients with anterior ischemic syndrome, 4 cases had narrow retinal artery, segmental changes of blood stream, vascular atresia, and abnormal arterio-venous anastomosis, and 2 cases had bold vascular loops. Conclusions The main manifestations of FFA in patients with low-perfused retinopathy are malperfusion and retinal ischemia, whose degrees relate to the extend of carotid artery stenosis or atresia, and the process of the disease.Serious retinal ischemia may combined with anterior ischemic syndrome.

Objective To explore the role of connective tissue growth factor(CTGF)in the mechanism of liver fibrosis.Methods Liver fibrosis models of rats were made by subcutaneously injecting with CCl4.On the other hand,32 human liver cirrhosis and 12 normal liver tissues were collected too.Immunohistochemical staining was used to detect the expression of CTGF in these tissues.Results The expression of CTGF in rats after injection with CCl4 was found mainly in hepatic stellate cells(HSC) and hepatocytes are all significantly higher than those in normal rats.Moreover,it presents with progressive tendency for the expression of CTGF in rats respectively at 1st,4th and 8th week after injection of CCl4.The same tendency was found in human normal and fibrotic liver tissues(P

Objective To investigate the distribution and virologic characteristics of HBV genotypes,and possible association with the severity of liver disease.Methods HBV genotype was determined,using oligonuleotides(oligo) microarray method.Results 37patients were differentiated as genotype B,69 genotype C.The clinical manifestations demonstrated that the serum lever of HBVDNA and HBeAg positive rate in patients of genotype C was 7.02?1.26 and 60.87% higher than 5.62?1.02and 32.43% in those of genotype B,the serum HBeAb positive rate in patients of genotype B was 67.57% higher than 39.13% in those of genotype C.The occurrence rates of those developed to chronic hepatitis B liver cirrhosis and hepatoma in those of genotype C were 46.38%,30.44% and 11.59% highter than that of 40.54%,13.51%and 8.11% in those of genotype B.Patients with genotype B were much younger than those with genotype C.Conclusions Genotype B and C exsited in Hangzhou,genotype C is a predominated genotype.The serum leverl of HBVDNA in those of genotype C is highter than that of genotype B.The positive rate of HBeAg in those of genotype B is highter than that of genotype C.The damage to liver induced by genotype C is severe than that of genotype B.

Objective To research the effects of different titers of bacteriophage D29 on growth and function of airway epithelial cell 9HTE.Methods Cell viability rates was analyzed after applying high(109 PFU/mL)and low(107 PFU/mL)titers of bacteriophage D29 and phage buffer respectively by MTT colorimetry.Additionally,the secretion levels of IL-6,IL-8 in cell culture supernatant were detected by ELISA.RT-PCR was performed to detect the expression of ICAM-1 mRNA.Cell apoptosis rate was analyzed by flow cytometry.Results There was no difference in cell growth,secretion levels of IL-6,IL-8,ICAM-1 mRNA and cell apoptosis rate between cells treated with high and low titers of D29 and phage buffer(P>0.05).Conclusion Neither high nor low titer of bacteriophage D29 exerts effect on growth and function of airway epithelial cell 9HTE in vitro.

Objective To analyze the short-term impact of fast track surgery (FTS) combined with minimally inva-sive surgery on elderly patients with colorectal cancer. Methods 200 patients with colorectal cancer received laparo-scopic surgery from July 2013 to July 2015 were selected and randomly divided into control group and FTS group. Patients in control group received conventional perioperative treatment and patients in FTS group received perioper-ative management according to fast track surgery. Status of intraoperative, postoperative recovery and the postopera-tive complication rate were compared between the two groups. Patients' quality of life were analyzed after two weeks of operation. Results Compared with the control group, the blood loss, operation time and number of lymph node dissection of patients in FTS group showed no significant difference ( > 0.05). Flatus time, ambulation time, start eating time, the infusion time and length of hospital stay in FTS group was significantly shorter than the control group, the difference was statistically significant ( <0.05). The total cost of hospitalization of FTS group was signifi-cantly lower than the control group ( <0.05). The incidence of sore throat, abdominal distension, lung infections and overall complications incidence rate in FTS group were significantly lower than the control group, the difference was statistically significant ( <0.05). The satisfaction rate in FTS group was 96.0%(96/100), and was significantly high-er than the control group 82.0 %(82/100), the difference was statistically significant ( < 0.05). QLQ-C30 results showed that scores of overall health, emotional function and social function of FTS group were significantly higher than the control group ( <0.05), and scores of nausea and vomiting, pain, insomnia, anorexia, constipation were sig-nificantly lower than the control group ( < 0.05). Conclusion Laparoscopy combined with FTS is safe and effective in treatment of colorectal cancer in the elderly patients, which can promote postoperative rehabilitation, improve pa-tient satisfaction and quality of life in short term.

Objective To provide imaging anatomy basis for percutaneous nephrolithotomy ( PCNL) by measuring relative displacement and changes in anatomical position of kidney and colon under the prone and low-oblique supine positions.Methods Forty-six patients scheduled for PCNL underwent 64-slice spiral CT scan under the prone and low-arch oblique supine position before the PCNL.The horizontal distance of kidney and colon,the distance from colon and analog puncturing line,the distance between the kidney and colon were measured and compared between the 2 positions.Results The distance from colon and analog puncturing line under the low-oblique supine and prone positions were as follows,the left (26.56 ±15.36) mm versus (12.25 ±13.16) mm (t=3.527,P<0.05),the right (25.85 ±14.26) mm versus (13.57 ± 12.53) mm (t=3.234,P<0.05).The differences of the rest distances between the 2 positions were not significant ( P>0.05).Conclusions The distance between colon and analog puncturing line increases in the low-arch oblique supine position,because the colon shifts to the ventral.The PCNL in low-arch oblique supine position may reduce the incidence of colon injury,and improve surgical safety.
