The traditional Chinese medicine (TCM) theory of "treating heart and brain diseases with same methods (Nao Xin Tong Zhi: NXTZ)" has great significance to the treatment of cardiovascular and cerebrovascular diseases. It has been proven effective by a great deal of clinical researches. However, the underlying mechanism for this theory is still unclear. To provide insights into the potential mechanism of "NXTZ", this study attempts to deeply investigate the mechanism from two representative cardiovascular and cerebrovascular diseases, coronary heart disease (CHD) and cerebral apoplexy. First, various data resources were integrated to obtain different types of biomedical entities including drugs, targets, pathways and diseases. Then, three different approaches including text mining, biological network and enrichment analysis were utilized to recognize the potential common features between CHD and cerebral apoplexy, and the corresponding functions of drugs which could treat both diseases, thus unveiling the mechanism of NXTZ.

OBJECTIVEThe theory of treating heart and brain simultaneously is from the theory of traditional Chinese medicine, and there aren't enough explanations for this theory from the perspective of molecular mechanism. As one successful case of this theory, the Chinese medicine formula--Buchang Naoxintong can achieve the goal of treating coronary heart disease and stroke at the same time. To illustrate the mechanism of the theory of treating heart and brain simultaneously, it is necessary to find out the molecular mechanism of this formula.

METHODUsing the network analysis method, together with two data mining methods-clustering and apriori algorithm, the frequent gene combinations interfered by the chemicals of the formula based on the protein-protein interaction networks related with coronary heart disease and stroke disease were figured out respectively. To find out the molecular mechanism of the theory of treating heart and brain simultaneously, the results got from two diseases were compared and analyzed.

RESULTBased on comparing two results from these two different diseases, the mechanism of the theory of treating heart and brain simultaneously was explained from molecular level by finding out key genes targeted by the components of this formula for both diseases and some particular genes interfered by the components for each disease. In addition, genes interfered indirectly by the chemicals for different diseases were found out based on the protein-protein interaction network.

CONCLUSIONIt can help to explain the molecular mechanism of the theory by our methods. By finding out the molecular mechanism of this theory, it can promote the progress of combination of Chinese traditional and Western medicine.

OBJECTIVETo explore the diagnosis and treatment of delayed traumatic epistaxis and put forward a concept of arteriola pseudoaneurysmal epistaxis originated from maxillofacial medium-sized artery.

METHODSThe clinical data of 53 patients who had the typical symptoms of delayed traumatic epistaxis and received digital subtraction angiography examination and treated in recent 10 years were retrospectively analyzed.

RESULTSAmong the 53 patients, 8 patients suffered from interval carotid artery pseudoaneurysm. For these 8 patients, 1 died of massive epistaxis before embolization, 7 received transcatheter arterial embolization( 6 cured and 1 died). Twenty patients suffered from traumatic carotid cavernous fistula, all were cured with endovascular occlusion by detachable balloon. Twenty-five patients suffered from maxillofacial artery hemorrhage. For these 25 patients, 21 were treated by transcatheter arterial embolization with gelatin sponge and coils, 4 by anterior ethmoidal artery ligation. The followed-up ranged from 6-72 months (median 5 years). All patients were successfully treated without serious complications and recurrent hemorrhage, except one patient who had recurred hemorrhage three weeks after transcatheter arterial embolization. This patient was again successfully treated by artery ligation.

CONCLUSIONSInterval carotid artery pseudoaneurysm, carotid cavernous fistula and maxillofacial medium-sized artery and arteriola pseudoaneurysm are the main causes of delayed traumatogenic epistaxis. Early diagnosis by digital subtraction angiography examination and transcatheter arterial embolization or artery ligation are the useful methods to treat delayed traumatic epistaxis and pseudoaneurysm.

Objective To evaluate the efficacy and safety of memantine in the treatment of patients with Alzheimer' s disease (AD).Methods This was a 16-week,multi-center,randomized,double blind, placebo-controlled clinical trial (Study 10116).A total of 258 AD patients (MMSE score 5—18) were randomized in a 1:1 ratio into either memantine 10—20 mg/day (MEM,n=128) or placebo (PBO,n= 130) group for 16 weeks.Efficacy was primarily assessed in terms of changes of severe impairment battery (SIB) score in patients from baseline up to SIB assessment in the 16th week (16-week completers set, CS16).While ehanges of MMSE,ADCS-ADL_(19),and NPI (neuropsychiatric inventory) were evaluated as secondary efficacy parameters on both CSI6 and full-analysis set (FAS).Safety was assessed by physical examination,lab assays,ECG,and adverse events.Results 236 subjeets (CS16:MEM n=117,PBO n=119) were eligible for the efficacy assessment.No statistically significant difference between the treatments was observed on the primary and seeondary efficacy analysis,although both treatment groups had a slight increase from baseline in SIB total score.Post hoe evaluation of the data identified two bias factors that had a significant impact on the results of the pre-protoeol specified primary and secondary analyses.In a re-analysis of the data (CS16_(modified),MEM n=94,PBO n=95) excluding patient data affeeted by these factors,memantine-treated patients showed a statistically significant improvement related to placebo in the 16th week on the SIB (MEM 2.2 vs PBO 0.3,P=0.04),MMSE (MEM 1.0 vs PBO 0.1,P=0.03),and ADL (MEM 0.1 vs PBO-1.6,P=0.02) scales,indicating that memantine improved the cognitive function of AD patients and stabilized the activity of daily life.Memantine was well tolerated with an adverse event profile similar to that of placebo.Conclusion This study provides further support for pre-existing data,showing that memantine is efficacious,safe,and well-tolerated in patients with moderate to severe AD.

Objective To analyze the epidemic features of anemia among students aged 6-11 years old in Minghang District,to provide basis for the control and prevention strategies of anemia among school students.Methods Surveillance on hemoglobin concentration was conducted among 42 872 students aged from 6 to 11 years old between 2012 and 2015.All data analyses were completed by SPSS 18.0 statistical software.Results The prevalence rate of anemia among school students 6-11 years old was 5.05％ (95％CI:4.84-5.26).The prevalence rate of anemia among girls was 5.28％,which was significantly higher than that 4.84％ among boys (x2 =4.24,P =0.037).Six-year-old boys and girls were most susceptible to anemia.Compared to students in Hope Schools,public school students are more vulnerable to anemia (boys:OR =2.37,95 ％ CI:2.03-2.76;girls:OR =2.08,95 ％ CI:1.74 -2.49).Overweight and obese students had a lower risk of anemia than average students (boys:OR =0.65,95 ％ CI:0.55-0.76;girls:OR =0.75,95 ％ CI:0.61-0.92).The three-year cumulative incidence of anemia was 12.80％ (95 ％CI:12.49-13.12).The cumulative incidence among girls was 14.52％,which was significantly higher than that of 11.28％ among boys (x2 =100.26,P＜0.001).Six-year-old boys have the highest three-year cumulative risk among all students,while 10-11-year-old girls have the highest three-year cumulative incidence.The risk of anemia in Hope School was found highest in all schools (boys:RR =1.93,95％CI:1.72-2.16;girls:RR =1.20,95 ％CI:1.04-1.39).Overweight and obesity were considered protective factors to anemia (boys:RR =0.75,95％CI:0.67-0.84;girls:RR =0.77,95％CI:0.68-0.88).The primary and recurrent detection rates of anemia were 14.58％ and 2.54％.The anemia among students was mainly detected during the first examination despite the differences in ages,schools and nutrition conditions (P ＜ 0.05).Conclusions The prevalence of anemia among primary school students in Minhang District is at a mild level.Control measures should be adopted,including monitoring of hemoglobin in all school children and adolescents,taking individual intervention measures based on results,promoting the health education for adolescent girls and parents of school children,and paying special attention to Hope School and students with recurrent and continuous anemia.

OBJECTIVE:To explore the association between the mitochondrial DNA(mtDNA)3537A/G,5351A/G variant and type 2diabetes mellitus(T2DM)in northem Chinese population.METHODS:The subjects including 614 patients with T2DM in Dalian City,61 of them were collected from family survey,497 of them were collected from Department of Endocrine,Dalian Municipal Central Hospital,and the remained 56 were selected from diverging T2DM patients in Dalian City.Additional 344 cases with normal carbohydrate toierance were served as controls.The mtDNA 3537A/G.5351A/G variants in 614 patients with T2DM and 334 healthy control subjects were examined.By sequencing the mtDNA in 24 cases and 26 controls,2 candidate SNPs in mtDNA were determined,and then genotyping was carried out by using PCR restriction fragment length polymorphism(PCR-RFLP)analysis.RESULTS:The frequency of mtDNA A3537G and A5351G mutation was 2.0%and 2.6% in T2DM patients,respectively,which was 2.1%and 4.2% in the control group.No significant difference had been observed between case and control(P＞0.05).After stratifying by body mass index and blood pressure,we found that the frequency of A5351 G in obesity patients with T2DM was 1.61%,and in obesity control was 15.38%,which had significant difference(P_(Fisher)=0.02,OR=2.76),however,A3537G stili showed no significant difference in all groups(P＞0.05).CONCLUSION:5351A/G in mtDNA ND2 gene may be a variance associated with T2DM in northem Chinese.

This study was purposed to investigate the ratio of Th17 cells and CD4(+)CD25(+)Foxp3(+) regulatory T (Treg) cells in peripheral blood of patients with chronic lymphocytic leukemia (CLL) and to explore their roles in the pathogenesis and clinical diagnosis. Based on the number of peripheral lymphocytes and treatment condition, the CLL patients were divided into 2 groups: untreated group (n = 30) and remission group (n = 15), the healthy control group (n = 20) was set up as well. The frequencies of Th17 and Treg cells of all cases were detected by flow cytometry (FCM). The results showed that frequencies of CD3(+)CD4(+)T cells and Th17 cells were significantly higher in untreated group than that in healthy control group (P < 0.05), the frequencies of CD3(+)CD8(+)T cells and Treg cells were significantly lower in untreated group than that in healthy control group (P < 0.05), the ratio of Th17/Treg was significantly higher in untreated group than that in healthy control group (P < 0.05). The frequencies of Th17 were not statistically different between remission and healthy control groups, the frequencies of Treg cells were significantly lower in remission group than that in healthy control group (P < 0.05), the ratio of Th17/Treg was significantly higher in remission group than that in healthy control group (P < 0.05), frequencies of Th17 cells were markedly lower in remission group than that in untreated group (P < 0.05). It is concluded that Th17/Treg imbalance exists in patients with CLL, which may play a key role in pathogenesis and development of CLL.
