Carotid ultrasound examination is a very mature examination method, it is widely used in clinical diagnosis and health checkup. Carotid ultrasound examination plays an important role in the prediction of the occurrence of cardiovascular disease. However, there are still certain problems in the application of the examination in the domestic health checkup population, which mainly include that the method and the standard are not unified, and the reporting form is not standardized. Carotid ultrasound examination must be standardized as soon as possible.

Objective: To screen for proteins which can interact with phosphotyrosine-interacting domain (PID) of differentially expressed gene in human ovarian cancer cell line DOC-2 by yeast-two hybrid technique, so as to provide evidence for the signal pathway of DOC-2. Methods: The cDNA sequence of human DOC-2 gene was amplified and its PID domain (nDOC-2) was subcloned into the bait vector pGBKT7 of yeast two-hybrid system; the product was then used to screen an embryo brain cDNA library and the proteins interacting with nDOC-2 were identified. Quadrople dropout(QDO) medium and X-?-gal were used for selecting the positive clones. PCA was used to analyze the amplified sequence. After elimination of the false positive clones, the positive clones were sequenced and analyzed by bioinformatic methods. Results:Twenty-one candidate positive clones were obtained and 3 of them were plasmids encoding Homo sapiens partial mRNA for betaglycan (TBR III gene), Homo sapiens protocadherin gamma subfamily C 3 (PCDHGC3), and APLP1(amyloid beta precursor-like protein 1).Conclusion: The proteins obtained in this study may play important roles in the signal pathway of DOC-2, which provides a new orientation for DOC-2 gene therapy of ovarian cancers

Objective To investigate the prevalence rate of nosocomial infections and the use of antibacterial agents in Zhejiang Cancer Hospital.Methods The cross-sectional survey on nosocomial infections was conducted among inpatients in Zhejiang Cancer Hospital on August 11,2011 and June 19,2012.The differences in prevalence rates of nosocomial infections,purposes of antibacterial agents use (for treatment,for prevention,or for both treatment and prevention),methods of medication (single or combined medication),and pathogen detections between 2011 and 2012 were analyzed with x2 test.Results There were 854 and 886 patients enrolled in the study in 2011 and 2012,and the prevalence rates of nosocomial infections were 5.27％ (45/854) and 5.08％ (45/886),respectively (x2 =0.186,P ＞ 0.05).Lower respiratory tract infection was the most common nosocomial infections both in 2011 and 2012,which accounted for 28.89％ and 36.96％ of all infections,respectively; and there was no significant difference in infection sites between 2011 and 2012 (x2 =1.415,P＞0.05).Totally 154 out of 854 patients (18.03％)in 2011 and 186 out of 886 patients (20.99％) in 2012 received antibacterial agents,and single medication was the most common.There were no significant differences in the purposes and methods of medication between 2011 and 2012 (x2 =1.994 and 3.042,P ＞ 0.05).Pathogen detections were performed in 56 out of 59 patients (94.92％) and 57 out of 65 patients (87.69％) who received antibacterial agents for treatment in 2011 and 2012,respectively.The most common pathogens were Escherichia coli,Pseudomonas aeruginosa,and Acinetobacter baumanni.Conclusion The prevalence rate of nosocomial infection in Zhejiang Cancer Hospital is of the satisfactory level,which is due to the good management of antibacterial agents use.

Background and purpose:Anastomotic leakage and low anterior resection syndrome(LARS) are both common complications in dual-anastomosis for patients with low rectal cancer. The aim of this study was to observe and explore the signiifcance and role of vertical cutting of the closed distal rectum in dual-anastomosis for patients with low rectal cancer.Methods:A total number of 120 patients with mid-low rectal cancer who admitted to and completed laparoscopic rectal cancer resection in the Department of General Surgery, the First Afifliated Hospital of Soochow University from Feb. 2010 to Jun. 2014 were pair-matched into Groups A and B based on their gender,age, tumor size, the distance of lower edge to the dentate line and tumor staging, etc. For the 55 patients in Group A (observation group), the rectum distal end was closed vertically instead of horizontally while disposing “the ifrst intestinal anastomosis”, intestine-intestine anastomosis was conducted in an “end-corner” approach when dealing with “the second intestinal anastomosis”, upper corner (“dog ear”) of the closed line in the distal end of the rectum was removed, the lower corner (“dog ear”) of the closed line in the distal end of the rectum was removed using vascular occlusion clamp method, and the T-shaped interchanges (“dangerous triangle”) of stapled sutures formed after anastomosis were strengthened with absorbable suture. For the 65 patients in Group B (control group), laparoscopic dual anastomosis was conducted using conventional method, and the two “dog-ears” and “dangerous triangles” were kept without any treatment. The clinical outcomes of the two groups of patients were analyzed retrospectively. Results:In group A, It was convenient to complete the operation when the “dog ears” and “dangerous triangle” on the vertical line after cutting the closed distal rectum vertically by “end-corner” anastomosis. The axis of intestine formed a certain angle making the closed distal rectum into “ampulla” sample without “dog ears”. the “dangerous triangle” were strengthened with absorbable suture. In group B, The distal and proximal intestine located on the same axis after intestine-intestine anastomosis leaving two “dog ears” and a “dangerous triangle”. The general clinical data of patients in the two groups were comparable and not signiifcantly different (P>0.05). The two groups of patients showed no signiifcant differences in blood loss, postoperative drainage, postoperative anastomotic bleeding, anal exhaust time, and length of hospital stay (P>0.05). However, the operation time as well as the numbers of anastomotic ifstula occurrence, defecation, tenesmus and post-operation re-ostomy differed significantly (P<0.05).Conclusion:Vertical cutting of the closed distal rectum with dual anastomosis made the “new” intestine closer to the physiological bending and morphology of the rectum, meanwhile, it simpliifed the approach of removing “dog ear” and strengthening “dangerous triangle”, ifnally it signiifcantly reduced the incidence of post-surgical complications.

BACKGROUND:At present, the internal fixation and fusion surgical treatment of lumbar degenerative disease tends to diversify, but posterior lumbar interbody fusion within a single bilateral pedicle screw fixation is stil common in clinical practice; the two ways after treatment can achieve satisfactory clinical efficacy, but which way has advantages is stil controversial. OBJECTIVE:To evaluate the efficacy and safety of unilateral and bilateral pedicle screw fixation and single segment lumbar interbody fusion in the repair of lumbar degenerative disease by a meta-analysis system. METHODS: According to the Cochrane Colaboration search strategy, we searched MEDLINE, PubMed, EMBASE, CBMdisc, CNKI, VIP and WanFang Data. Randomized controled trials concerned unilateral and bilateral pedicle screw fixation and single segment lumbar interbody fusion in the treatment of lumbar degenerative diseases. By two reviewers, in strict accordance with inclusion and exclusion criteria, literatures were screened, data were extracted, and the methodology quality of included trials was criticaly assessed. RevMan5.1 software was used for meta-analysis. RESULTS AND CONCLUSION: Six randomized controled trials involving 507 patients were included. The results of meta-analysis showed that fixed unilateral and bilateral pedicle screw between single lumbar fusion and surgery in the treatment of lumbar degenerative diseases, significant differences were detected in surgical time [WMD=-40.29, 95% CI (-43.79, -36.79)], intraoperative blood loss [WMD=-74.13, 95%CI (-86.13,-62.13)], length of hospital stay [WMD=-1.04, 95%CI (-1.30,-0.79)], final folow-up Visual Analogue Scale score [WMD=0.33, 95% CI (0.24, 0.42)], final folow-up Oswestry dysfunction index [WMD=-1.07, 95%CI(-1.57, -0.56)]; unilateral side was better than bilateral side (P < 0.000 1). There was no significant difference in complication rate [RR=0.54, 95% CI(0.25, 1.17)] and fusion rate [RR=0.53, 95%CI (0.22, 1.28)] (P=0.12 andP=0.16). These results suggested that unilateral and bilateral pedicle screw fixation and single lumbar fusion in the treatment of lumbar degenerative disease has achieved satisfactory results. Unilateral pedicle screw fixation can reduce operation time, intraoperative blood loss and length of stay. Visual Analogue Scale score and Oswestry dysfunction index improved significantly in a short period after treatment.

Purpose To explore the clinical value of ultrasound in charactering brain anomalies in open spina bifida at 11-13+6 weeks of gestation.Materials and Methods Abdominal and transvaginal ultrasound was performed in 125 cases of normal fetus and 4 cases of confirmed open spina bifida at 11-13+6 weeks of gestation to compare the morphology of intracranial translucency (IT), diencephalon and midbrain.Results Fetal IT was readily recognized in all 125 normal cases, with diencephalons and midbrain showing number 8 shape. In 4 cases of open spina bifida, fetal IT cannot be identified, and the expected 8 shape of diencephalon and midbrain was distorted.Conclusion Fetal brain characteristics including intracranial translucency and the shape of diencephalon and midbrain in 11-13+6 weeks gestation are valuable ultrasound screening indicators for open spina bifida.

Aim To express h-ERA and h-ERA C-terminal domain in E.coli and prepare antiserum against human ERA. Methods Human era(h-era) cDNA and h-ERA C-terminal domain gene were amplified by PCR and ligated with prokaryotic expression vector pRSET-C and pDH respectively. E.coli TAP106 transformed with the recombinant plasmid pDH-h-era-C was induced at 42℃ to express h-ERA C-terminal domain protein. Antiserum against h-ERA was prepared by immunizing rabbit with h-ERA C-terminal domain protein purified by SDS-PAGE. E.coli BL21(DE3) transformed with the recombinant plasmid pRSET-C-h-era was induced with IPTG to express (His)6-h-ERA fusion protein for Western-blot analysis.Results The expressed h-ERA C-terminal domain and (His)6-h-ERA fusion protein occupied about 40％ and 80％ of total bacterial protein respectively. The(His)6-h-ERA fusion protein expressed in E.coli can be detected with the rabbit antiserum. Conclusion The h-ERA C-terminal domain protein and (His)6-h-ERA fusion protein were expressed with high efficiency in E.coli, and the rabbit antiserum against h-ERA was prepared successfully.
