Objective To evaluate the diagnostic value of tissue Doppler imaging (TDI) in classification of fetal arrhythmias, and conclude characters of each type of arrhythmias by analyzing wave forms of TDI. Methods Fifty-five fetuses suffered arrhythmia were included in study group. By comparing the results with control standard(M and PW), the sensitivity, specificity and reliability of TDI in diagnosis of fetal arrhythmias was calculated. At last, the character of waves by TDI of each type of arrhythmia was concluded. Fetal kinetocardiogram was made to identify the origin of arrhythmias. All cases were asked to perform electrocardiography and echocardiography examination after birth. Results The sensitivity, specificity and reliability of TDI was 98%, 100% and 100%, respectively. The character of atrioventricular waves and kinetocardiogram of 8 types fetal arrhythmias were conclude. Conclusions TDI has great value in classification of fetal arrhythmias.

Objective To study the structural features and characteristics of a novel gene Schistosoma japonicum 79(Sj79), and observe its effect of RNA interference(RNAi),so as to provide the experimental basis for its further function study and mechanism study of anti reproductive development of schistosome. Methods The gene structure and characteristics of Sj79 were analyzed by bioinformatics methods. Then the expressions of Sj79 messenger RNA(mRNA)during the different develop?mental stages of schistosome were analyzed and the effects of RNAi silencing were observed by the soaking method. The tran?scriptional levels of Sj79 after RNAi were detected by real time PCR. Results The open reading frame of Sj79 contained 696 base pairs with an exon structure. The gene had obvious stage specificity,and its transcriptional level in mature female worms was the highest. After soaking for 3 d,the Sj79 mRNA level[(41.0 ± 12.3)%]in the siRNA?1 group with low dosage(20 nmol/L) was lower than that in the siRNA?NC group[(103.2 ± 14.4)%],the difference was statistically significant(t=3.28,P<0.05). When with high dosage(200 nmol/L ),both the Sj79 mRNA levels in the siRNA?1 group[(15.8 ± 10.9)%]and siRNA?2 group [(11.1 ± 8.8)%]were significantly lower than that in the siRNA?NC group[(100.1 ± 6.3)%](t=13.44,27.84,both P<0.01). After soaking for 7 d,only the Sj79 mRNA levels in the siRNA?1group[(43.4 ± 4.5)%]and siRNA?2 group[(62.5 ± 5.4)%]with low dosage were lower than that in the siRNA?NC group[(100.4 ± 5.2)%],and the differences had statistical sig?nificance(t=8.33,5.07,both P<0.01). Conclusion Through this study,we have improved the mRNA sequence and genom?ic information of Sj79 gene,and understood its structural features,as well as selected out two effect fragments siRNA?1and siR? NA?2 which will provide the basic evidences for the further study on egg laying interference of the female adult worm of schisto?some in vitro.

Objective: To investigate the therapeutic effect of creatine phosphate sodium (CP, Neoton) at early stage of myocardium diastolic dysfunction. Methods: A total of 138 cases with myocardium diastolic dysfunction were divided into CP group (n=109) and routine treatment group (n=29). All the patients received routine treatment. The CP group received CP treatment based on routine treatment(CP 2g+5%glucose or 0.9% sodium chloride 100ml, iv. drip, for patients with mild diastolic dysfunction was 1time/d, patients with moderate diastolic dysfunction was 2 times/d), duration was 7~14 days. Color-coded Doppler echocardiography was used to detect transmitral peak early diastolic velocity (E-wave),transmitral peak late diastolic velocity (A-wave),peak early diastolic velocity of mitral annulus (Ea), and peak late diastolic velocity of mitral annulus(Aa), and the value of E/A ,Ea/Aa and E/Ea were calculated. Symptoms, signs and items from echocardiography were compared between the two groups before and after treatment. Results: After treatment, all symptoms and signs of patients in two groups significantly improved (P<0.05~0.01), and the marked effective rate in CP group was significantly higher than that of routine treatment group (96.2% vs. 57.1%, P<0.01). In CP group, the marked effective rate of E/A (81.65% vs. 10.34%), Ea/Aa (83.49% vs. 13.79%) and E/Ea (92.86% vs. 12.00%) were significantly higher than those in routine treatment group (P<0.01all). Conclusion: Creatine phosphate possesses marked effect for improve patient’s condition and diastolic dysfunction.

OBJECTIVE:To investigate the risk factors for secondary pulmonary fungal infection in patients with severe craniocerebral trauma after tracheotomy,and to provide reference for clinical prevention and treatment. METHODS:In retrospective study,87 severe craniocerebral trauma patients with secondary pulmonary fungal infection after tracheotomy were selected from Ezhou Municipal Central Hospital(called"our hospital"for short)during Jan. 2014-Jun. 2017 as observation group;87 severe craniocerebral trauma inpatients without secondary pulmonary fungal infection after tracheotomy were selected as control group. The distribution and drug resistance of infected fungal in observation group were analyzed. χ2 test and binary Logistic analysis were adopted to investigate risk factors of secondary pulmonary fungal infection in patients with severe craniocerebral trauma after tracheotomy. RESULTS:Totally 174 clinical specimens were detected in observation group of our hospital;7 kinds of fungus were detected and isolated from 87 strains,and the fungi with high detection rate were Candida albicans(41 strains,47.13%)and Candida glabrata(23 strains,26.44%). The resistance rates of C. albicans and Candida tropicalis to commonly used antifungal agents as fluconazole,itraconazole and fluoncytosine were lower than 20%;resistance rates of C. glabrata to fluconazole,itraconazole and fluoncytosine were more than 25%,to amphotericin B and nystatin were lower than 20%. χ 2test and binary Logistic analysis showed that independent risk factors of secondary pulmonary fungal infection included hypoproteinemia,Glasgow coma score(GCS,<8 points)at admission,serum creatinine clearance(<30 mL/min)at admission,tracheal incision ventilation time(≥7 days),the time of antibiotics use(≥14 days),combined use of antibiotics,the use of carbapenems and systemic glucocorticoid [odd ratios were 3.02,2.98,2.21, 2.05,2.48,2.35,4.74,5.97;95%CI were(1.59,5.74),(1.58,5.63),(1.18,4.41),(1.11,3.78),(1.34,4.59),(1.27,4.34), (2.49,8.35),(3.08,11.49),P<0.05]. CONCLUSIONS:The fungus of secondary pulmonary fungal infection in patients with severe craniocerebral trauma after tracheotomy in our hospital are mainly C. albicans and C. glabrata,which are sensitive to commonly used antifungal agents. Hypoproteinemia,GCS at admission,serum creatinine clearance rate at admission,tracheal incision ventilation time,the time of antibiotics use,combined use of antibiotics,the use of carbapenems and systemic glucocorticoid are independent risk factors of secondary fungal infection in patients with severe craniocerebral trauma after tracheotomy. It is necessary to pay attention to predictive value of above risk factors,improve sensitivity and specificity of diagnosis and treatment. Antifungal agent should be selected rationally according to the results of drug sensitivity test. At the same time,early prophylactic or empirical antifungal treatment should be given in time for high risk patients with above factors.

Objective:To compare the clinical utility of mammography with automated breast ultrasound system (ABUS) for detecting breast lesions. Methods:Data of 142 patients with 149 breast lesions who underwent both mammography and ABUS in Tianjin Medi-cal University Cancer Institute and Hospital were collected from Jnly 2016 to September 2016. The detection rates of the two methods were then determined. Results:The overall detection rate using ABUS was significantly higher than that of mammography (mammog-raphy: 87.2% vs. ABUS: 98.0%, P<0.05). However, no significant difference was observed in breast cancer detection rates between mammography and ABUS (mammography:91.1%vs. ABUS:97.0%, P<0.05). Moreover, the benign lesion detection rate was significant-ly higher in ABUS than in mammography (mammography:79.2%, vs. ABUS:100%, P<0.05). In dense breasts, the detection rates of overall lesions, breast cancers, and benign lesions for ABUS were 97.7%, 96.5%, and 100.0%, respectively;whereas those for mammog-raphy were 86.0%, 90.6%, and 77.3%, respectively (P<0.05). Owing to overlapping dense breast tissue and deep anatomic location, sev-eral lesions were missed on mammography. Conversely, most lesions missed on ABUS presented as calcifications. Conclusion:Com-pared with mammography, ABUS can detect more lesions especially in dense breasts. However, ABUS failed to detect calcifications, whereas mammography had distinct advantages in this regard. Overall, the two methods had potential supplementary value for breast cancer screening.

Background and objective All the advanced NSCLC patients that received EGFR-TKI therapy will eventually relapse after a period of efficacy. The aim of this study is to investigate the serum biomarkers as potential predictive factors for the efficacy of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) targeted therapy in advanced non-small cell lung cancer. Methods Twenty serf-paired serum samples were collected from 9 advanced NSCLC patients that evaluated as disease control (SD or PR) after gefinitib therapy, at the time points of before and after gefinitib treatment but 2 weeks before being evaluated as disease progress. AII samples were pre-separated by WCX microbeads, and then detected on the MALDI-TOF-MS platform of Bruker AutoflexTM. ClinProTools (Version: 2.1) was used to analyze the differentially expressed proteins. Results There were 7 protein peaks (m/z), 3 242.09, 8 690.36, 2 952.64, 3 224.04, 1 450.51, 1 887.8 and 3 935.73 found statistically differentially expressed between the self-paired samples. Three proteins (3 242.09, 2 952.64 and 3 224.04) were down-regulated and four proteins (8 690.36, 1 450.51, 1 887.8 and 3 935.73) up-regulated in gefinitib treated sera. Conclusion The data here suggest that several specific protein peaks might indicate gefinitib resistance, yet the identities of these proteins and the mechanisms underlying the responsiveness to gefinitib treatment need further investigation.

PURPOSE: The aim of this study is to explore signal transducer and activator of transcription 3 (STAT3) expression in breast cancer and to analyze the detailed mechanism that STAT3 contributes to the progression of breast cancer. METHODS: We retrospectively analyzed the clinicopathologic characteristics and overall survival (OS) of 140 breast cancer patients after curative surgery, and detected STAT3 expression, phosphorylated STAT3 (pSTAT3) expression, Ki-67 expression, vascular endothelial growth factor (VEGF)-C and -D expression in breast cancer tissues, and adjacent nontumor tissues. Survival analysis and relationship analysis were adopted for demonstrated the important mechanism of STAT3 contribution to progression of breast cancer. RESULTS: STAT3 expression, pSTAT3 expression, Ki-67 expression, VEGF-C expression, and VEGF-D expression in breast cancer tissues were significantly higher than those in adjacent nontumor tissues, respectively. With survival analysis, only number of lymph node metastasis (N stage) was identified as the independent predictors of the OS of breast cancer patients. Besides, we demonstrated there was the most prominent correlation between STAT3 expression and lymph node metastasis in breast cancer tissues by using the multinominal regression method. CONCLUSION: STAT3, a poor survival biomarker potential association with lymph node metastasis, was suitable for predication the OS of breast cancer patients after curative resection.
