The disease incidence of aortic dissecting aneurysm showed an increasing tendency.Recently,the clinical application of endovascular stent-graft implantation received good results in treating aortic dissecting aneurysm,which is characterized by minimally invasive,safe,with high success rates.However,the chosen of anesthesia is still in dispute.Local anesthesia,intraspinal anesthesia and general anesthesia can be used in this operation.The investigation demonstrated that intubation general anesthesia is more security in this operation with less complication,which is conductive to controlling blood pressure and braking conditions.

OBJECTIVE: To discuss the distribution laws of traditional Chinese medicine (TCM) syndrome factor and their combination in coronary heart disease (CHD), and to study the correlation between the TCM syndrome factor combination and cardiac function as well as blood-lipid. METHODS: The parameters of the cardiac function of 300 patients with a final diagnosis of CHD by coronary angiography were measured by echocardiography, and the levels of blood lipids in the CHD patients were detected. An analysis of the correlation was done between the TCM syndrome factor combination and cardiac function as well as blood-lipid in CHD. RESULTS: The TCM syndrome factor combinations of CHD were blood stasis due to qi deficiency, qi and yin deficiency, intermingled phlegm and blood stasis, and yang deficiency and blood stasis. The ejection fraction of CHD patients with yang deficiency and blood stasis was markedly decreased. The levels of triglyceride and low-density lipoprotein cholesterol in CHD patients with intermingled phlegm and blood stasis were markedly increased, and the level of triglyceride in CHD patients with qi and yin deficiency was markedly increased too. CONCLUSION: The treatment of CHD should aim directly at the symptoms and causes. It is also proved that some compound traditional Chinese herbal medicines for supplementing qi and activating blood circulation, nourishing yin and resolving phlegm, and activating yang should be used in treatment of CHD. In cases of CHD with low cardiac function, particular emphasis should be laid on activating yang and blood circulation, while in cases of CHD with blood-lipid disturbance, particular emphasis should be laid on resolving phlegm and activating blood circulation, replenishing qi and nourishing yin.

Objective To observe the clinical therapeutic efficacy of prescription of supplementing qi and activating yang on sick sinus syndrome. Methods According to the random number table, 231 patients with sick sinus syndrome were randomly divided into treatment group and control group. One hundred and fifty patients in the treatment group were given the Chinese herbal medicine while the other 81 patients in the control group were given atropine. The therapeutic course was four weeks in each group. The changes of clinical manifestations and electrocardiogram (24 h Holter monitoring ECG) of two groups were compared. Results The total effectiveness of treatment group was 98.67% (148/150), the control group was 41.98% (34/81), there was a significant difference in the clinical curative efficacy (P<0.01). The total effective rate of the treatment group was 87.3%(131/150) and that of the control group was 35.9%(29/81), and the average increases of heart rates in 24 hours were 9/min and 4/min, respectively. There was significant difference between the two groups (P <0.05). Conclusion The prescription of supplementing qi and activating yang was effective in improving the clinical symptoms and heart rates of patients with sick sinus syndrome.

The sodium hydrogen exchanger 1 (NHE1), which functions in maintaining the ratio of Na+ and H+ ions, is widely distributed in cell plasma membranes. It plays a prominent role in pH balancing, cell proliferation, differentiation, adhesion, and migration. However, its exact subcellular location and biological functions in Toxoplasma gondii are largely unclear. In this study, we cloned the C-terminal sequence of T. gondii NHE1 (TgNHE1) incorporating the C-terminal peptide of NHE1 (C-NHE1) into the pGEX4T-1 expression plasmid. The peptide sequence was predicted to have good antigenicity based on the information obtained from an immune epitope database. After induction of heterologous gene expression with isopropyl-b-D-thiogalactoside, the recombinant C-NHE1 protein successfully expressed in a soluble form was purified by glutathione sepharose beads as an immunogen for production of a rabbit polyclonal antiserum. The specificity of this antiserum was confirmed by western blotting and immunofluorescence. The antiserum could reduce T. gondii invasion into host cells, indicated by the decreased TgNHE1 expression in T. gondii parasites that were pre-incubated with antiserum in the process of cell entry. Furthermore, the antiserum reduced the virulence of T. gondii parasites to host cells in vitro, possibly by blocking the release of Ca2+. In this regard, this antiserum has potential to be a valuable tool for further studies of TgNHE1.

【Objective】 To analyze the metagenomics and microbiology of voluntary blood donors in China, so as to assess the potential threats of emerging infectious diseases to the safety of blood transfusion. 【Methods】 12 300 plasma samples (10 mL each) collected by central blood stations in Chongqing, Liuzhou, Urumqi, Mianyang, Wuhan, Nanjing, Mudanjiang, and Dehong Prefecture area from 2012 to 2018 were subjected to total DNA extraction after ultracentrifugation (32 000 rpm/min, centrifugal radius 91.9 mm) in minipools of 160 donations. The metagenomic library was constructed, and deep sequencing was conducted by Illumina Hiseq 4 500. By comparing with reference sequences of bacteria, fungi, parasites and viruses, metagenomic data were analyzed, classification of microbes were identified, and potentially harmful pathogens were evaluated. 【Results】 A total of 632 GB clean data were obtained by deep sequencing, and the top three pathogens were Pseudomonas(0.561 1%), Burkholderia(0.468 7%) and Serratia(4.242 0%). Pathogens with potential threat which could be transmitted by blood transfusion or blood products were found, such as human parvovirus B19(0.126 6%), Leishmania spp(1.348 5%) and Toxoplasma gondii(0.615 8%). 【Conclusion】 Our study analyzed metagenomics of voluntary blood donors in parts of China and revealed pathogens that may cause potential harm to blood safety, which were helpful for targeted prevention and control of emerging infectious diseases.
