Medical imaging plays a more important role in diagnosis and treatment of diseases with the rapid development of big data technologies and hospital information systems.It is thus quite necessary to develop the effective and accurate medical imaging retrieval systems.The key techniques for text-based, contents-based and semantic-based medical imaging retrieval methods were thus elaborated and analyzed with the prospects put forward for the future development direction of medical imaging retrieval techniques.

Objective To analyze on the efficacy and toxicity of MAAE (MIT ,Ara-C,AMSA,VP16)regimens on treating refractory and relapsed acute leukemia in adult patients. Methods MAAE (MIT, Ara-C,AMSA, VP16) regimen, which consisted of MIT 10mg/d (d1～3), intravenousdrop, Ara-C 200mg/d (d1～7),intravenousdrop, AMSA 75 mg/d (d1～3), intravenousdrop VP16 100 mg/d(d1～4), intravenousdrop were used to treat 25 cases of adults with refractory and relapsed acute leukemia (AL). G-CSF 5 μg/kg were used every day when WBC＜0.5×109/L. Results In the 25 cases with refractory and relapsed acute leukemia, 14 cases (56 %) reached complete remission, 5 patients(20 %) reached partial remission, the total effective rate was 76 %. Conclusion MAAE regimen was a very effective alternative treatment for CR induction in adult patients with refractory and relapsed AL and low toxicity.

Clinical guidelines,coming into being with the development of evidence-based medicine,are of great significance in reducing medical malpractice and regulating medical behaviors.However,more effective and intelligent measures should be taken for their development and application due to their low utilization and poor compliance of doctors in their implementation.The emergence and structure of clinical guidelines were elaborated with related problems summarized.The knowledge expression models of digital clinical guidelines were analyzed and compared with the challenges faced by the current knowledge expression models of clinical guidelines pointed out.

In chronic kidney disease (CKD), inflammatory responses during the progression of renal tissue and tissue injury related causes its progression to end-state renal disease. Among them, nuclear factor (nuclear factor, NF)-kappaB signaling pathway by regulating the corresponding nuclear expression of target gene transcription, as well as affecting the synthesis of inflammatory mediators, induction of inflammation lead to kidney damage and renal fibrosis. Some single herbs and their extracts (such as Astragali Radix, Scutellariae Radix, Ginkgo Folium) and some traditional Chinese medicine (such as Danggui Buxue decoction, Qilian decoction) can reduce the inflammatory damage induced by renal tissue NF-kappaB signaling pathway and delay the progression of CKD.

Re-evaluation of bioequivalence of generic drugs is one of the key research focus currently. As a means to ensure consistency of the therapeutic effectiveness of drug products, clinical bioequivalence has been widely accepted as a gold standard test. In vitro dissolution testing based on the theory of the BCS is the best alternative to in vivo bioequivalence study. In this article, the conventional dissolution method and flow-through cell method were used to investigate the dissolution profiles of domestic amoxicillin capsules in different dissolution media, and the absorption behavior of the drugs with different release rates (t85% = 15-180 min) in the gastrointestinal tract was predicted by Gastro Plus. The flow-through cell method was thought better to reflect the release characteristics in vivo, and amoxicillin capsules with regard to the release rates up to 45 min (t85% = 45 min) were having a satisfied bioequivalence with the oral solution according to the C(max) and AUC. Although two different dissolution profiles of domestic amoxicillin capsules were found by flow-through cell methods, prediction results revealed that domestic capsules were probably bioequivalent to each other.

Objective To investigate the impact of 1,25(OH)2D3 on histological changes and activation of STAT3 in BLM?induced pulmonary fibrosis mice. Methods 30 male C57BL/6 mice were randomly divided into control group ,BLM group and BLM+VD group. Mice in BLM group and BLM+VD group received intratracheal injection of BLM(3 U/kg). Control group were intratracheally injected equal volume of sterile saline. From the first day after the surgery,mice in BLM+VD group received intraperitoneal injection of VD (5μg/kg·d). After 21 days, H&E and Masson′s trichrome staining were carried out. Aschroft score were used to evaluate histological changes in lungs. IL?6,IL?4 and INF?γin BALF were assessed by Elisa. p?STAT3,α?SMA and Collagen I were detected by western blot (WB) and immunohistochemistry. Results Fibrosis score and level of α?SMA,Collagen I in BLM group were significantly higher than that in control group (P < 0.05). However ,treatment with VD effectively at?tenuated fibrosis (P<0.05). IL?6 and IL?4 increased while INF?γwas decreased in BALF of BLM group (P<0.05). VD could ameliorate these changes. Upregulation and neuclear translocation of p?STAT3 were observed in BLM group,while VD intervention could inhibit phosphorylation of STAT3. Conclusions VD attenuate BLM?induced pulmonary fibrosis and regulate inflammatory cytokines probably by blocking STAT3 activation.

A comprehensive physician authorization management system has been established at Renmin Hospital of Wuhan University in its effort of promoting the clinical standardization.This system covers authorization of prescription,disposition,surgery,and medical report among others,adhering to the principle of clear,complete quantitative competence-based,authorization.The training and assessment of physicians in parallel canimprove physicians' competence and quality of care.

Objective To investigate the operational technique of laparoscopic splenectomy and pericardial devascularization (LSPD) and evaluate the clinical efficiency of this method for the treatment of portal hypertension.Methods With the new understanding of anatomical space around the spleen,the cardia and the fundus,two gaps and two tunnels can be created in LSPD.Retrospective analysis was made on the clinical data of patients who underwent LSPD from Jun 2013 to Mar 2015.The operative time,intraoperative blood loss,postoperative hospital stay,conversion rate and postoperative complication rate were measured.Results A total of 189 cases underwent surgery successfully,including 34 cases of splenomegaly and 21 cases of severe esophageal varices.The operative time was (125 ± 52) min,intraoperative blood loss (58 ± 32) ml,postoperative hospital stay (7.5-2.1) d.There were 4 conversion cases in this study.Conclusions The splenic pedicle and stomach pedicle can be safely dissected with the two gaps and two tunnels principle,which makes LSPD safe and convenient.

Objective To systemically review the effect of ulinastatin on lung function in pediatric patients undergoing cardiopulmonary bypass.Methods PubMed,Embase,Cochrane Controlled Trials Reg-istry,China National Knowledge infrastructure,China Biology Medicine disc,VIP and Wanfang databases were searched from their inception to October 2015.Articles regarding the use of ulinastatin on lung function in patients undergoing cardiopulmonary bypass were searched.Studies were screened by two independent re-viewers and then the data were extracted.The methodological quality was evaluated according to the inclusion and exclusion criteria.Meta-analysis was then performed using RevMan 5.1 software. Results Nineteen eligible studies (n = 657 patients)were identified.The results of meta analysis showed that ulinastatin could improve the oxygen partial pressure(SMD=0.90,95%CI 0.52-1.28,P <0.01)and oxygenation index (SMD=1.01,95%CI 0.45-1.56,P <0.01),decrease the PA-a O2 (SMD= -0.87, 95%CI -1.70--0.03,P =0.04),reduce the respiratory index (SMD=-0.81,95%CI -1.51--0.11, P =0.02),Lower the airway peak pressure (SMD=-0.83,95%CI -1.18--0.48,P <0.01),improve the dynamic compliance (Cd)(SMD=1.10,95%CI 0.57-1.62,P <0.01),and shorten the breathing ma-chine ventilation time (SMD=-0.98,95%CI -1.59--0.36,P <0.01).Conclusion This meta-analysis showed that ulinastatin treatment had a certain degree of protective effects on lung function in pediatric pa-tients undergoing cardiac surgery with CPB,but further research was needed for all these studies which were not multicenter,strictly controlled.
