In order to acquire the information on the changes and improvement after the implementation of National Schistosomiasis Control and Prevention Regulation, a survey was performed. The awareness of schistosomiasis and the regulation, stool management and other related contents were carried out in the rural areas of Jiangsu, Anhui, Jiangxi, Hubei, Hunan, Sichuan and Yunan provinces. The results showed 98.9% of the residents knew about schistosomiasis, 89. 8% knew the regulation, 95. 1% supported the management of drinking water and lavatory, 45.3% used tap water as their ordinary drinking water supply, but there were 47.6% still drank well water, 51.1% used water closet and 40.0% used simple toilet. The work on improving water and sanitary conditions in mountain areas was left behind that in lake areas. It is indicated that there is still a lot we must do to promote the propaganda of the regulation.

OBJECTIVE: To explore the effect and mechanism of kidney-warming and astringent therapy in treating nephrotic syndrome patients with deficiency of spleen and kidney yang and overflow of water, and to observe the change of plasma endothelin and interleukin-2 receptor after treatment. METHODS: Forty-four patients were randomly divided into conventional steroid treated group (control group, 20 cases) and conventional steroid plus kidney-warming and astringent therapy treated group (treatment group, 24 cases). The levels of plasma endothelin (ET) and soluble interleukin-2 receptor (sIL-2) were observed. RESULTS: Before treatment, plasma ET and sIL-2 in the patients were significantly higher than those in healthy people (P<0.01). After treatment, the ET and sIL-2 levels were obviously improved in both treated groups (P<0.05) and the improvement in the treatment group was more obvious. The difference between the two treated groups after treatment was significant (P<0.05). CONCLUSION: Conventional treatment plus kidney-warming and astringent therapy can effectively improve the levels of plasma ET and sIL-2 in treating nephrotic syndrome patients with deficiency of spleen and kidney yang and overflow of water, and hence alleviate the damage of renal tissue.

Objective To construct the eukaryotic expression vector of pcDNA3.1-PEA-15 and express it in the human esophageal cancer (EC-109) cells,and to explore the effect of PEA-15 on EC-109 cells.Methods The PEA-15 gene was amplified from EC-109 by reverse transcriptase polymerase chain reaction (RT-PCR) and ligated to eukaryotic expression vector pcDNA3.1.After confirmation of recombinant plasmid was correctly by endonuc]eases digestion and DNA sequencing,the construct was transfected it into EC-109 through liposome inducing.The expression of PEA-15 in transfected EC-109 was detected by RT-PCR and Western blot.The cell growth inhibition ratio was evaluated by MTT assay.Results RT-PCR indicated that PEA-15 was highly expressed in EC-109 cells.The amplified fragment by RT-PCR was coincident with hypothesis enzyme digestion analysis and DNA sequencing confirmed that the pcDNA3.1-PEA-15 was constructed successfully.The expression of PEA-15 gene was increased obviously in the transfected EC-109 detected by RT-PCR and Western blot respectively (t =4.078,5.269,P ＜ 0.05).The cell growth inhibition ratio in the group which transfected pcDNA3.1-PEA-15 was significantly lower compared with the pcDNA3.1 transfect group after 72 hours (t =6.163,P ＜ 0.05).Conclusions The recombinant eukaryotic expression vector pcDNA3.1-PEA-15 is constructed successfully,and it can be expressed in EC-109.It also shows that PEA-15 has the function on cell growth which suggests that PEA-15 can inhibit the apoptosis of EC-109 cells and its expression involved in esophageal cancer development.

ObjectiveTo evaluate the accuracy and value of the ultrasonography and magnetic resonance imaging (MRI) in the diagnosis of agenesis of the corpus callosum in the newborns.MethodsConventional cerebral ultrasound screening was performed in 8086 newborns admitted to NICU in our hospital from January 2012 to June 2014 and agenesis of the corpus callosum was suspected or conifrmed in 31 newborns. The diagnostic accuracy of ultrasonography was assessed through the com-parison between the results of ultrasonography and MRI.ResultsIn 31 cases with suspected agenesis of the corpus callosum, ultrasonography showed 14 cases of complete agenesis of which 13 cases had the same diagnosis with MRI except one case of partial agenesis, meanwhile, ultrasonography showed 16 cases of partial agenesis of which 15 cases had the same diagnosis with MRI except one case of complete agenesis. One case of abnormal corpus callosum determined by ultrasonography was diagnosed as partial agenesis by MRI. MRI showed there were other brain malformations in 14 cases.ConclusionsUltrasonography and MRI has a high consistency in the diagnosis of agenesis of the corpus callosum in neonates, so the former can be used as a routine screening and the latter can be used as a method of accurate diagnosis. A combination of both has an important role in early diag-nosis and clinical evaluation.
