ABSTRACT
Objective To investigate the expression of Scinderin(SCIN myoprotein) in breast cancer tissues and adjacent tissues,and to explore the relationship between the expression of Scinderin and different molecular subtypes of breast cancer as well as the clinical factors.Methods Immunohistochemical staining method was used to detect the expression of SCIN in 120 cases of breast carcinoma and 30 adjacent tissues.The relation between SCIN expression in breast cancer tissue and molecular subtypes,pathologic stage,age,tumor size,lymph node metastasis was analyzed.Results SCIN expression level in breast cancer tissue was lower than in the tissues adjacent to carcinoma (6.06±3.32 vs 7.77±3.32,P＜0.05).SCIN expression was associated with breast cancer molecular subtypes (P＜0.05),and it was irrelevant with age,tumor size,histological grade,lymph node metastasis,or clinical stage (P＞0.05).Conclusions The expression of SCIN in breast cancer tissues was lower than in the adjacent tissues.It is associated with breast cancer molecular subtypes.SCIN could become the protein markers of breast cancer molecular targeted therapy.
ABSTRACT
Objective To investigate the risk factors of thrombopenia(TP)in septic patients complicated with acute kidney injury (AKI).Methods Two hundred and sixty five septic patients complicated with AKI admitted in Intensive Care Unit ICU of Zhejiang Provincial People''s Hospital during January 2012 and December 2016 were enrolled in the study.The clinical data, results of laboratory tests, Acute Physiology and Chronic Health Evaluation (APACHEII) scores, Sequential Organ Failure Assessment (SOFA) scores, therapeutic intervention, and 28-day mortality were documented.Among 265 patients, TP occurred within 7 days in 112 cases (TP group) and did not occur in 153 cases (non-TP group).Multivariable Logistic regression analysis was performed to analyze the risk factors of TP.Results The 28-day mortality rate in TP group was higher in TP group than that in non-TP group (47.3% vs.33.3%, χ2=5.307,P<0.05).Univariate analysis showed that age, C-reactive protein (CRP), procalcitonin (PCT) and APACHEII score, SOFA score, continuous renal replacement therapy (CRRT), heparin anticoagulation, shock, usage of linezolid and bloodstream infections were associated with TP in septic patients with AKI(all P<0.05).Multivariable Logistic regression analysis showed that age≥65 (OR=4.53, 95%CI 1.23-9.24,P<0.05), CRRT(OR=5.24,95%CI 2.14-14.56,P<0.01), heparin anticoagulation(OR=4.56,95%CI 2.13-8.46,P<0.01), usage of linezolid(OR=2.35,95%CI 1.25-5.24,P<0.01), shock(OR=2.15,95%CI 1.03-4.96,P<0.01)and bloodstream infections(OR=4.26,95%CI 1.36-12.48,P<0.01)were independent risk factors for septic patients with TP.Conclusion For septic patients with AKI having these risk factors, the platelet counts should be closely monitored, and intervention measures should be given to reduce the occurrence of TP.
ABSTRACT
Objective To develop an Modified Early Warning Score (MEWS) table suitable for professional characteristics and to predict the occurrence of complications in the percutaneous coronary intervention (PCI). Methods This is a retrospective study. PCI patients in catheter room of Qingdao International Center Hospital from July to December, 2015 and July to December, 2016 were selected as the research object. The former was set as the control group, and the latter as the experimental group, traditional MEWS and modified MEWS were applied in the two groups respectively. The incidence of complications were compared between two groups. Results The incidence rates of cardiac arrest, drop of blood pressure, arrhythmia, slow blood flow or no complex flow, perforation, interlayer were 0.83％(3/362), 0.55％ (2/362), 0.55％ (2/362), was 0.55％ (2/362), 2.21％ (8/362) , 4.42％ (16/362) , and were 2.51％(9/358), 5.31％(19/358), 8.66％(31/358) , 3.07％(11/358) , 2.51％(9/358) , 2.79％(10/358) in the control group, the differences were statistically significant (χ2= 4.603-5.302, P<0.05). Conclusions The MEWS score of PCI can be used to predict the occurrence of complications in PCI, and for the patients with MEWS score above 5, they should be given medical and nursing intervention in order to reduce the complications in the operation.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the short-term outcomes and complication management of submucosal tunneling endoscopic resection(STER) for esophageal submucosal tumors (SMTs) originating from the muscularis propria(MP) layer.</p><p><b>METHODS</b>Clinical data of 48 patients with esophageal SMTs from MP layer undergoing STER in the Department of Gastroenterology, the First People's Hospital of Xiangshan, Zhejiang, and the Endoscopy Center of Zhongshan Hospital, Fudan University, Shanghai between September 2013 and August 2014 were retrospectively analyzed. The clinicopathological features, complication management, and short-term outcomes were evaluated.</p><p><b>RESULTS</b>All the patients underwent STER successfully. The complete resection rate was 100%. The mean maximum diameter of the lesions was (22.9±12.1) mm (range 9.0-60.0 mm), and the mean operation time 41.8 min (range 15.0-140.0 min). Intraoperative mucosal injury occurred in 5 patients (10.4%), which was successfully clipped, pneumoperitoneum in 2 patients (4.2%) and subcutaneous emphysema in 3 patients(6.3%), which were successfully controlled with conservative treatments. Five patients (10.4%) had postoperative severe chest pain. Seven patients (14.6%) developed fever, among them, 5 were managed by conservative therapy, and 2 were submucosal tunnel infection, who were successfully treated after reclosing the ruptured tunnel entry with clips. All the removed tumors had tumor-free resection margins. The average length of postoperative hospital stay was 2.4 days (range 1-13 days). Local recurrence and distant metastasis did not occur during mean 6.8 months (range 2-12 months) follow up.</p><p><b>CONCLUSIONS</b>STER appears to be a safe and effective option for esophageal SMTs originating from MP layer. Common complications related to STER often can be successfully controlled with conservative treatments.</p>

Objective To observe the blood biochemical and histological changes before and after pancreas freezing, to provide evidence for cryosurgery for pancreatic cancer. Methods Fifteen healthy pigs were divided into deep frozen group (n = 5), shallow frozen group (n = 5), non-frozen group (n = 3) and normal group (n = 2). After anesthesia and Iaparotomy, a probe of the Argon-Helium Surgical System was inserted into the pancreas, 100% and 10% argon output power were used in deep and shallow frozen group, respectively;and the temperature were - 130 ～ - 140℃ and - 110 ～ - 120℃, respectively;which results in an ice-ball with 15 ～ 20 mm in diameter. Then helium gas was inputted to increase the temperature to 10 ～ 20℃ for three minutes;then the whole process was repeated. A probe was inserted into the pancreas in the non-frozen group only and only laparotomy was performed in non-grozen group normal group and normal group. Serum amylase, IL-6, CRP levels before and after the experiment was determined;the pigs were sacrificed at day 7 and the pancreas was harvested for light microscope and electron microscope examination. Results The frozen pancreatic tissue became pitchy necrosis zone, and it could be distinguished from non-frozen tissue;there were obvious tissue necrosis in the center and para-center of frozen area, and the ultra-structure were destroyed and disappeared, mitochondria degranulation and rough endoplasmic reticulum degrannlation were observed. Serum amylase was elevated in 13 (86.7%) pigs and most returned to normal at 6th day. Serum IL-6 was slightly elevated in 5 (33.3%) pigs. There was no significant difference among all the groups in term of serum CRP. All the pigs were alive until the time of sacrifice. Conclusions Cryosurgery has affirmative fatal ablative effects on pancreatic tissue, and it is safe with no serious complications.
