Objective To analyze comprehensively the investigation data of the national schistosomiasis surveillance sites from 2005 to 2007, in order to provide the evidence for mastering the endemic situation and pattern of schistosomiasis. Methods Eighty surveillance sites were selected, and the investigation data about schistosomiasis in residents and domestic animals and the status of Oncomelania snails in these sites were collected and analysed. Results From 2005 to 2007, the total infection rate in residents decreased by 54.90% (average decreased by 18.30% each year). The sites where the infection rate in residents was higher than 5% decreased year by year. In 2007, there was no site where the infection rate in residents was higher than 5% in all the 80 surveillance sites. All the infection rates in different age groups decreased for three years in succession, and the peak appeared at 30-50 age group in 2005, but moved to 50-60 age group in 2007. The infection rate in domestic animals decreased by 69.22%, and the infection rate in cattle and buffaloes remarkably decreased. For the three years, the areas with snails reduced by 8.84%, and the areas with infected snails reduced by 53.23%. The average densities of living snails and infected snails decreased year by year, but the infection rate of snails fluctuated during the three years. Conclusion The endemic situation of schistosomiasis in residents and cattle, and the status of snails, in general, remarkably decreased from 2005 to 2007.

Objective To survey and understand the endemic situation of schistosomiasis in China in 2007,so as to provide the evidence for decision-making of schistosomiasis control.Methods The data of investigation on schistosomiasis in residents,domestic animals,Oncomelania snails and other relative factors were collected and analysed in the 80 national surveillance sites,2007. Results In 2007,the total infection rate of the residents was 0.92%,which decreased by 42.31% compared with that in 2006. There was no site where the resident infection rate was more than 5% among all the 80 surveillance sites. The peak of the resident infection rate with different age groups appeared at the 50-60 age group. The cattle and buffalo were still the main infection targets. The infection rate of domestic animals was remarkable decreased. The density of living snails was 0.430 0/0.1 m2. The percentage of frames with living snails was 0.06%. The density of infected snails was 0.000 7/0.1 m2,and the snail infection rate was 0.16%. All of them were decreased compared with those of 2006. Conclusion The schistosomiasis endemic in the residents,cattle and snails was remarkable decresed in the national surveillance sites,2007.

This article is based on the searching from the United States Library of Congress Web Search science 2005 for the literature on the birth femoral fractures,reviewing its incidence,pathogenesis and treatment of such fractures of the latest developments,for the purpose of the provision of orthopedic and obstetric physician reference.Literature showed that neonatal birth femoral fractures might occur whether deli-veries were through the birth canal or by cesarean section.Whenever faced with fetal asphyxia,intracranial hemorrhage,such as critical state,it is critical to save the life of fetal babies,regardless of treatment.The prognosis of neonatal femoral shaft fractures is normally good without deformity left.

Objective To understand the endemic situation of schistosomiasis among 80 national surveillance sites for schistosomiasis in 2006,so as to provide scientific evidence for making out schistosomiasis prevention and control measures. Methods According to the national surveillance protocol, the endemic situation of schistosomiasis in residents and livestock, and the status of Oncomelania snails and other factors were investigated in the 80 national surveillance sites for schistosomiasis, and all the data were collected and analysed. Results Among the 80 national surveillance sites,the average positive rate of residents with sera examination was 13.60% and the average positive rate with stool examination was 1.59%.The average positive rate of floating population with sera examination was 5.79%. There were 143 advanced patients among the national surveillance sites, and 12 acute patients were reported in 2006, but no breaking-out epidemic reported. The proportion of domestic animals stable breeding were about 4.74% of 5 365 examined animals in 2006, and the others were not.The infection rate of domestic animals was 5.93% that declined by 34.49% compared with that in 2005 and especially for the infection rate of cattle and sheep. A total of 7 429.63 hm2 of areas were surveyed. The areas of snail habitats, infected snail habitats and the new snail habitats were 4 994.01,621.75 hm2 and 21.75 hm2,respectively. The density of living snails and infection rate of snails were 0.544 8/0.1 m2 and 0.37%, which increased compared with infection rate of 0.26% in 2005. Conclusion The endemic situation of residents, cattle and snail habitats declined in 2006 compared with those in 2005 in the national surveillance sites.

The progressive injury of retinal ganglion cells ( RGCs) is a common occurrence in several eye diseases, which ultimately may lead to irreversible blindness. Currently, there are still no effective or ideal treatments for it in practice, however some recent studies show that stem cell transplantation may provide a promising new idea for neuroprotection and replacement of retinal ganglion cells. This paper will review the research progress of stem cell transplantation-based treatment.

Objective To survey and understand the endemic situation of schistosomiasis among 80 national surveillance sites in China in 2008, so as to provide the evidence for decision-making of schistosomiasis control. Methods According to the National Surveillance Protocol for Schistosomiasis, the data of schistosomiasis in residents, domestic animals and Oncomelania snails and other relevant factors were collected and analyzed in the 80 national surveillance sites. Results Among the 80 national surveillance sites, the average positive rate of residents with sera examination and the average infection rate of the residents were 9.86% and 0.67% , respectively, and the infection rate of domestic animals was 1.62% , all remarkably decreased compared with the rates of 2007, but the proportion of domestic animals stable breeding was only 6.07% . The areas of infected snail habitats and the new snail habitats were 177.70 hm~2 and 7.64 hm~2, respectively. The mean density of living snails and infection rate of snails were 0.32/0.1 m~2 and 0. 15% , respectively. Conclusions The endemic situation of residents, domestic animals and snails decreased in 2008 compared with those in 2007, and domestic animals are still the main infection sources of schistosomiasis, the management of domestic animals need to be further strengthened, meanwhile the surveillance and control of snails should be focused on.

With the popularization of ureteroscopy, ureteral avulsion has become a common complication of urological surgery in recent years. In the study, we reviewed the clinical management of 2 patients who underwent emergency ureterostomy and selective operation of ileoureteral substitution, emergency repair and selective operation of Boari-flap ureteroneocystostomy respectively. After 22 and 17 months of follow-up, no ureter stricture were found, and hydronephrosis were relieved compared with preoperative in both.

The leaves of Rumex dictyocarpus Boiss et Buhse are used for treatment in acute abdomen. From this plant four constituents have been isoiated and identified as emodin、chrysophanol、quercetin、quercitrin by chemical and spectroscopic methods. These constituents were known to possess antibacterial, anti-inflammatory or hemoslatic actions, it seems that the clinie effects are related to the presense of these constituents.
