Objective To discover the operating problems through analysis of the financial situations of the rehabilitation institutions. Methods According to the different regions and different levels of rehabilitation institutions, 416 representative institutions from 26 provinc-es, municipalities and autonomous regions were surveyed. Results 329 effective questionnaires were recalled. 57.75%institutions relied on the superior departments in charge of funding, 51.09%institutions were in breakeven state. They were lack of sustainable development pow-er, and the capital expenditure was mainly used for staff salaries and equipment purchase. Conclusion To solve the shortage of funds in the development of rehabilitation institutions, we should establish a long-term mechanism of internal and external compensation.

In this research was developed high efficiency method using 125I for directly labeling KH901, a tumor-specific oncolytic recombinant adenovirus, biodistribution of 125I-labeled compound in normal mice was investigated. 125I-KH901 was prepared by N-bromosuccinimide labeling method to find the optimal ratio of labeling response. The compounds were isolated and purified by Sephadex-G10 agarose and the radiochemical purity of compounds was analyzed by paper chromatography. The radioactivity biodistribution in mice was measured at different times after caudal vein injection with 0.1ml 125I-KH901. The labeling yield of 125I-KH901 was 78% and the radiochemical purity was 95% after purification by Sephadex-G10 agarose. Biodistribution revealed that the uptake of 125I-KH901 in liver was higher than in other organs at all time points of the experiment. 125I-KH901 was mainly concentrated in liver, kidneys, spleen and lung. It can be seen that N-bromosuccinimide labeling method is an optimal method with simple steps and high labeling yield in labeling KH901 with 125I. 125I-KH901 has a biodistribution trait which is an advantage to treating liver tumors.

This review aims to evaluate the quality of studies assessing the value of 99mTc-MIBI myocardial perfusion imaging in the diagnosis of coronary artery disease. OVID (1956 to 2006), CBMdisc (1978 to 2006), CNKI (2005 to 2006) and VIP (2005 to 2006) for relevant studies in English and Chinese were searched and identified. Quality assessment of diagnostic accuracy studies (QUADAS) items were used. Studies were classified and Meta-disc software was used to analyze sensitivity, specificity, positive likelihood ratio and negative likelihood ratio for the pooled analysis and heterogeneity test, then Asymmetric SROC curves were drawn for those without heterogeneity. In 29 articles included, the results of the pooled analysis showed that, as for rest, exercise and drug myocardial perfusion imaging, the pooled LR + were 2.209, 4.334 and 5.508, the pooled LR- were 0.224, 0.141 and 0.195, and for dipyridamole myocardial perfusion imaging, the pooled LR+ and LR- were 5.031 and 0.193, respectively. Besides, for stress myocardial perfusion imaging among the patients without myocardial infarction history, the pooled LR+ and LR- were 6.176 and 0.199, respectively. The biases from the 29 studies were mainly due to diagnostic test results review bias; variations were probable and were correlated with the spectrum of disease and inclusion criteria; the quality of report was moderate. The conclusion is that 99mTc-MIBI stress MPI, especially dipyridamole MPI, is valuable for diagnosing coronary artery disease.

For a long time past viruses have been recognized as being tumoricidal. At present, researchers are still pursuing studies and constructing more suitable oncolytic viruses for treating different malignant tumors. Herpes simplex virus type 1 (HSV-1) has been known as the most potential oncolytic virus among all the viruses. In this overview, we summarize the current situation of oncolytic viruses, the biology of HSV-1, its construction and application of its recombinant, and we debate on the feasibility and prospect of HSV-1 mutants labeled with radionuclides for cancer therapy.

In order to evaluate the biological activity in vitro and the antitumor effects of 131I-conditionally replicating oncolytic adenovirus KH901 on HepG2 human hepatoma xenografts, the leves of GM-CSF expression were determined by ELISA method. A panel of tumor and normal cells was infected with recombinant adenovirus KH901 at MOI of 10 PPC. The medium was harvested to determine the bioactivity of GM-CSF after 24 hours. Nude mice bearing HepG2 human hepatoma xenografts were given 131-KH901. Antitumor effects were assessed using endpoints of tumor growth delay. The data showed that after 24 hours 131-KH901 replicated hugely in tumor cells and produced significant amount of GM-CSF 183.27 +/- 6.90 pg/ml, while producing very small amount of GM-CSF 20.44 +/- 0.77 pg/ml in normal cells. In the treatment of tumor, 131I-KH901 showed higher restraint rate (71.3%) compared to 131I (22.7%) or KH901 (52.7%). Therefore, 131-KH901 can inhibit the growth of human hepatoma cell in nude mice and it may be a potential drug for treating liver cancer.

Objective To evaluate the probability of siblings identification in Identifiler system by using the software of automatic analysis.Methods Using the software of automatic analysis in siblings jdentification.STP genetic typing of 151 pairs of full siblings and 31224 pairs of unrelated individuals from manual simulation were analyzed in 15 STR loci of ldentifiler system.Results Kin probability(W_(FS))of 39.07% full siblings were more than 99.999% while W_(FS) of unrelated individual pairs were 0% .W_(FS) of 60.93% full siblings and 21.3% unrelated individual pairs were all at the range from 99.999% to 1% .W_(FS) of 78.7% unrelated individual pairs 0% full siblings individuals were less than 1% .Therefore,there were notability difference between full siblings and unrelated individual pairs.In addition,testing of 15 STR loci of Identifiler system,it suggested that the pair were siblings when the locus number of the entirely-same is not less than 5 or that of the entirely-different is not more than 1,and that the pair were unrelated individuals when the locus number of the entirely-different is not less than 6 or that of the entirely-8alne is not more than 1.Conclusion The software of automatic analysis and the Identifiler system call be used to siblings identification.
