ObjectiveTo evaluate the application effect of clinical pathways in hospitalized inguinal hernia patients by using the Meta- analysis. MethodsPublished randomized controlled trials (RCT)in hospitalized inguinal hernia patients were searched and screened in CNKI、VIP、CBMdisc and Wanfang datebase under present standards.The quality of the included studies were evaluated and statistically analyzed by RevMan5.0 software. ResultsTotally 16 literatures including 1649 cases were eligible to the criteria (816 in clinical nursing pathways group and 833 in the traditional health education group)altogether.The Meta-analysis showed there were significant difference between the clinical pathway group and the traditional health education group in grasp of health knowledge,rate of patients,satisfaction degree,length of hospital stay and hospitalization expenses. ConclusionsClinical pathways is superior compared with the traditional health education for hospitalized inguinal hernia patients.

Objective To screen the prevalence of nutritional risk in cirrhotic inpatients by Nutritional Risk Screening 2002 (NRS 2002) and explore the relationship between nutritional risks and outcomes.Methods NRS 2002 was used to identify the nutritional risk of 200 cirrhotic inpatients between May 2010 and May 2011.The Child-Turcotte-Pugh (CTP) grade,fatality,complications,and length of stay within 6 months were followed up to explore the relationship between nutritional risks and outcomes.Results The prevalence of nutritional risk screened by NRS 2002 was 53.5％ in cirrhotic patients.The prevalence of nutritional risk was 39.0％,59.4％,and 60.0％ respectively in patients with CTP grade A,B,and C (P =0.029).Compared with those without nutritional risks,patients with nutritional risks had significantly higher incidences of complications and fatality (P =0.000 and 0.013) and longer hospital stay (P =0.001).Conclusion The nutritional risk increases along with the CTP grade.Patients with nutritional risks tend to have poorer outcomes.The influence of nutrition support on the outcome of patients with liver diseases needs further research.

Hypoxic-ischaemic brain injury is a main cause to neonatal death and children neural handicap,and therapeutic efficacy is bad for the completely injured nerve cells.The development research of mesenchymal cells transplantation has a good prospect to treat this disease.

Vasculogenic mimicry (VM) is a term that describes a novel form of angiogenesis, channels of which are patterned networks of interconnected loops of periodic acid-Schiff (PAS)-positive extracellular matrix forming by highly aggressive tumor cells instead of endothelial cells. VM is closely correlated with the invasiveness, metastasis and prognosis of related tumors. However, traditional anti-vascular therapies aiming at endothelial cells have no remarkable effects on malignant tumor with VM. Therefore, VM should be an important factor to consider in design of anti-angiogenesis therapies of highly aggressive tumors and it is expected to become a potential target for tumor therapy. Some recent progresses of anti- vasculogenic mimicry therapy are reviewed in this article.

ObjectiveTo investigate the effects of X-linked inhibitor of apoptosis (XIAP) siRNA or XIAP antagonist Embelin on the growth inhibition and apoptosis of hepatcellular cancer cell line HepG2,which was treated by tumor necrosis factor-related apoptosis (TRAIL). Methods HepG2 cells were tranfected either by XIAP siRNA or a negative control,followed by treatment with TRAIL,Embelin or a combination of the two.XIAP expression,cell growth,and caspase-3 activity were determined by Western blot,MTT assay and fluorescent caspase-3 assay,respectively.Cleaved PARP expression levels of were measured by Western blot.ResultsThe XIAP protein expression was significantly downregulated by transfection with XIAP siRNA.Compared with the negative control,the XIAP siRNA significantly inhibited the growth of HepG2 cells treated by 100ng/ml(6.8％ ±1.2％ vs.11.8％±4.0％,P＜0.05)and 1000 ng/ml (18.9％ ±2.0％ vs.26.6％ ±1.5％,P＜0.01)by TRAIL.TRAIL-induced caspase-3 activation and PARP cleavage were also increased significantly by XIAP siRNA transfection.In addition,Embelin also significantly inhibited cell growth (P＜0.01),activation of caspase-3 (P＜ 0.01) and TRAIL-induced PARP cleavage.Conclusions Both XIAP siRNA and Embelin may potentially contribute to clinical treatment of hepatocellular carcinoma.

Induced pluripotent stem (iPS) cell based on recently developed stem cell reprogramming technique holds great hope for regenerative medicine,in vitro disease modeling and drug evaluation.Recent progress on clinical hematology includes in vitro generation of hematopoietic progenitors and mature blood cells from somatic cells,iPS cells derived from chronic myeloid leukemia cells for the better understanding of the resistance mechanisms of bcr-abl inhibitor imatinib,and moreover,correction the monogenic inherited disease using gene-targeted strategies.However,whether the iPS cells can fully replace human embryonic stem cells still needs further investigation.

Objective Statistics and analyze the effect of comprehensive prevention measures for the ventilator associated pneumonia (VAP) morbidity and mortality,and investigate its actual applicate situation in the clinical.Methods Statistics and analyze the clinical date of 183 cases of our ICU mechanical ventilation patients in 2012 (group A),including morbidity,mortality,time of endotracheal intubation,length of stay and the primary pathogenic bacteria,and to compared with the relevant clinical data of 192 cases of our ICU mechanical ventilation patients in 2011 (group B),summarize and analysis the actual applicate situation of the comprehensive prevention measures in the clinical through the data contrast.Results The incidence of VAP in group A was lower than that in group B [31.7％(58/183) vs.58.3％(112/192)] (P ＜ 0.05),but the mortality was no statistical difference in both groups (P ＞ 0.05) ; the endotracheal intubation time and the average length of stay in group A were less than those in group B [6.3 d vs.10.6 d,7.6 d vs.11.9 d](P＜0.05); the main pathogenic bacterium of VAP with mainly gram-negative bacilh.Conclusions Comprehensive prevention measures can effectively reduce the incidence of VAP,but the mortality rate has no significant effect,need further clinical research;comprehensive prevention measures to reduce patients with tube time also confirm its effectiveness.Comprehensive prevention measures are economical and practical,is worth in clinical promotion.

BACKGROUND:Chronic ankle instability affects normal life severely. Therefore, chronic ankle instability causes more and more attention of experts, and choice of reasonable and effective diagnosis and targeted treatment method for chronic ankle instability in early stage has become an important issue in the clinic.
OBJECTIVE:To review literature research on the diagnosis and treatment of chronic ankle instability in recent years, and to provide reference and evaluation criteria for the diagnosis and reasonable and effective treatment of chronic ankle instability in clinical practice.
METHODS:We searched PubMed database, China National Knowledge Infrastructure, Wanfang database and VIP database for clinical and basic experimental research on chronic ankle instability. Keywords were“chronic ankle, instability, diagnosis, rehabilitation exercises, surgery methods, research progress”in Chinese and“chronic ankle, instability, diagnosis, rehabilitation exercises, surgical methods, research”in English. Total y 40 literatures were analyzed.
RESULTS AND CONCLUSION:Because of the special anatomical features and biomechanical advantages of the ankle, we should first consider the early diagnosis and effective treatment in chronic ankle instability patients. The treatment should focus on the anatomic characteristics, biomechanic characteristics, etiology of chronic ankle and diagnostic methods of the ankle joint. Conservative treatment and rehabilitation exercises after surgery play a major role in the recovery of chronic ankle instability. The use of balance board, tilting board, and climbing machines is an effective rehabilitation exercises for chronic ankle instability. The application of AOFOS-hind foot and ankle fibula reaction time is important for the assessment of functional recovery of the ankle joint. The emergence of arthroscope is an important clinical research direction of ankle surgery. This plays a significant effect on the treatment of chronic ankle instability.
