1.Soluble ST2 and its prospects of clinical application in cardiovascular disease
Chinese Journal of Laboratory Medicine 2014;37(12):969-972
Soluble ST2 (sST2) is a decoy receptor of IL-33 in blood.sST2and ST2L (receptor on cell membrane) seem to be markedly induced in mechanically overloaded cardiac myocytes,especially the expression of sST2.A large number of sST2 bind IL-33 thus subtracting IL-33 from the interaction with ST2L,potentially attenuating the cardioprotective effects of IL-33/ST2L pathway.Recently,sST2 has emerged as a novel for heart failure biomarker.Though sST2 was a less robust marker for the diagnosis of heart failure than NT-proBNP,it has been implicated in the prognostication of patients with acute dyspnea,acute or chronic heart failure and myocardial infarction,with particular value for mid-and long-term prognosis.However,further studies are needed in order to better point out the evidence for a routine use of sST2 evaluation in patients suffering from cardiovascular diseases.

Objective To analyze the efficacy of umbilical one trocar laparoscopic appendectomy (UOTLA) in treatment of complicated appendicitis in children. Methods Clinical data of 78 cases of children patients with complicated appendicitis from January 2012 to October 2015 was summarized, including 44 cases as UOTLA group received umbilical one trocar laparoscopic appendectomy, 34 cases as OA group received open appendectomy. Then statistically analyzed all the patients' operation time, postoperative hospital stay, postoperative abdominal abscess, incision infection, early inflammatory intestinal obstruction and pain level. Results The laboratory test results of C reaction protein (CRP) had no significant difference between the two groups, while peripheral white blood cell count decreased more significantly in UOTLA group than that in OA group; the operation time of UOTLA group was shorter than that in OA group with no statistical difference [(66.59 ± 33.24) vs (72.86 ± 30.36) min, P > 0.05], but postoperative hospital stay was shorter [(8.21 ± 1.67) vs (9.21 ± 2.01) d, P < 0.05]. Abdominal abscess after operation: 3 cases in UOTLA group, while 1 case in OA group (P > 0.05); incision infection: 6 cases in UOTLA group, 9 cases in OA group (P > 0.05); early inflammatory intestinal obstruction: 1 cases in UOTLA group, 5 cases in OA group (P > 0.05); the pain level, postoperative recovery time was significantly shorter in UOTLA group compared with OA group (P < 0.05). The average expenses comparison of the two groups has no statistical difference [(10639.37 ± 2970.92) vs (10765.04 ± 2902.64) yuan, P > 0.05]. Conclusion UOTLA is safe and effective for complicated appendicitis in children due to minimally invasive, less pain and faster recovery without significant increase in the cost and postoperative complications. It can be applied in children with purulent, perforated appendicitis and gangrene, perforated appendicitis and other complicated appendicitis.

BACKGROUND: The full three-dimensional finite element model can not only establish a realistic three-dimensionalmodel, but also can simulate the osteotomy on the model. Analysis of biomechanics guides the clinical operation.OBJECTIVE: To establish a three-dimensional finite element model of ankylosing spondylitis kyphosis and provide an effective digital platform for further studies.METHODS: A 30-year-old male patient with ankylosing spondylitis kyphosis participated voluntarily in the current study. CTimages obtained from CT transverse scanning from C1 to the sacrococcyx were imported into Mimics 17.0 software toestablish a three-dimensional geometric model of the posterior spine. The geometric model was then imported into Studio Geomagic 2013 software. For the subsequent optimization of image processing, the posterior spine convex geometry wasestablished on the three-dimensional geometric model. We used Unigraphics NX 8.5 to establish the spinal kyphosis surfacemodel, then added modeling of calcification of the ligaments, partial resection of useless sacral bone, and finally, imported themodel into ANSYS 15.0 finite element analysis software, then added the ligaments and set the parameters of the material,generating a complete three-dimensional finite element model of ankylosing spondylitis.RESULTS AND CONCLUSION: A three-dimensional finite element model of complete ankylosing spondylitis wassuccessfully established. Using the ten-node approach, we generated 398370 tetrahedral elements, and 668538 nodes.This will provide a reliable digital platform for the next step of biomechanical analysis.

Objective To assess these in a consecutive series of patients with ICC treated surgically. Methods A retrospective study was conducted on 189 ICC patients undergoing surgery.Surgical results and survival were evaluated and compared among different subgroups of patients.Univariate and multivariate analyses were performed to identify prognostic factors.Results R0,R1,R2 resection and exploratory laparotomy were obtained in 63,84,31 and 11 patients,respectively.The overall 5 -year survival rates for the entire cohort were 16.8%,with corresponding rates of 26.3% for patients with R0 resection;14.3% for patients with R1 resection;6.8% for patients with R2 resection;and 0.0% for patients with an exploratory laparotomy.Independent factors for poor survival included positive resection margin,multiple tumors,beta - catenin nuclear expression and lymph node metastasis. Conclusion R0 resection offers the best possibility of long -term survival,but the chance of a R0 resection is low when surgery is performed for potential resectable ICC.Patients with characteristics of beta -catenin nuclear expres-sion,multiple tumors and lymph node metastasis are indicated to surgery which is needed to be further studied.
