Objective To determine the diagnostic and assessment value of soluble urokinase plasminogen activator receptor (suPAR) level in septic patients.Methods Totally 82 septic patients in the Department of Intensive Care Unit of The First Affiliated Hospital,Sun Yat-Sen University were prospectively analyzed from June 2013 to March 2014.Another 29 patients with systemic inflammatory response syndrome (SIRS) and 15 healthy subjects served as controls.Septic patients were divided into sepsis group (n =27),severe sepsis group (n =27) and septic shock group (n =28) according to the severity,and there was no significant difference in age and sex among these groups.Measurement of plasma suPAR,serum procalcitonin (PCT) and C-reactive protein (CRP) levels,and calculation of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure assessment (SOFA) score were performed.Comparison of group differences for continuous variables was done by oneway ANOVA or nonparametric Kruskal-Wallis test.Spearman rank correlation analysis was applied to establish the relation between variables.Receiver operating characteristics (ROC) curve was created and area under curve (AUC) was calculated to determine the diagnostic value of these variables in sepsis.Results The levels of plasma suPAR in SIRS group,sepsis group,severe sepsis group,septic shock group,and healthy control group were (8.22±0.61),(11.45±1.12),(12.99±1.28),(15.75± 1.23) and (4.65 ±0.30) ng/mL,respectively.Plasma suPAR levels in SIRS group and sepsis group were higher than that in healthy control group (P < 0.01),and elevated plasma suPAR was accompanied by increased severity of sepsis (P < 0.05).PCT levels of sepsis group (17.66 ± 8.42) ng/mL,severe sepsis group (9.67 ±3.56) ng/mL and septic shock group (29.19 ± 10.78) ng/mL were greater than that in SIRS group (1.10 ± 0.78) ng/mL,P < 0.01.CRP levels elevated in all groups,but there were no significant differences among them.When suPAR and CRP were applied to distinguishing sepsis from SIRS,the AUC values from suPAR and combination of suPAR and PCT were 0.817 (P < 0.01,95 % CI:0.714-0.921) and 0.927 (P<0.01,95% CI:0.870-0.985),respectively.Using9.52 ng/mL suPAR as the best cut-off to distinguish sepsis from SIRS,there were 71.93% sensitivity and 95.46% specificity.The levels of plasma suPAR positively correlated with PCT levels (r =0.326),APACHE Ⅱ score (r =0.492) and SOFA score (r =0.386),P < 0.01.Conclusions Plasma suPAR levels significantly elevated in septic patients and correlated with the severity of sepsis.Sepsis and SIRS may be discerned by plasma suPAR levels.Joint use of suPAR and PCT could greatly increase the specificity of diagnosis of sepsis.

AIM: To study the neuroprotective effect and possible mechanism of ganglioside GM 1 on neonatal hypoxic-ischemic-encephalopathy(HIE). METHODS: A rat model of neonatal HIE was established, then the pathological changes and expressions of nitric oxide synthase (NOS) in the brain tissues were investigated in different periods after hypoxia-ischemia (HI) and the subseqent changes of the above results after GM 1 administrated. RESULTS: The damage of the brain exposed to HI were alleviated significantly after GM 1 administrated. The levels of NOS expressions in the brain tissue increased after HI. GM 1 could inhibit NOS expressions induced by HI. CONCLUSION: GM 1 may have some protective effects on neonatal HIE, and the possible mechanism is related to the partial inhibition of NOS expression.

Objective To test the effect of an APP in the adherence of inhalation medicines for children with asthma,improve the rate of inhalation medicines compliance,self management ability and the quality of life of children with asthma.Methods The research use self-control study.We use Medication Adherence Report Scale for Asthma (MARS-A) to test the adherence of inhalation medicines for children with asthma in outpatient department.After 2 months using the APP,the children with asthma may be re-tested by the MARS-A to compare the differences in medication adherence,asthma knowledge,use method and pulmonary function,etc.Finally,data analysis using paired t test.Results After using the APP,the inhalation medicines adherence rate is increased from 25.78 % to 68.75 %,the awareness rate of patients and their caregivers are increased from 25 % to 65 %,and the APP usage rate is 42.18%,there was significant difference (P<0.01).Conclusion The APP can effectively improve the adherence of inhalation drugs,standardized medication management,guarantee treatment effect and improve the quality of life of children with asthma.It could also reducing medical costs and improving work efficiency and service quality,thus deserves promotion.

OBJECTIVETo evaluate the clinical value of the four regions 12-core systemic prostate biopsy.
METHODSNinety-one patients suspected of prostate cancer received four regions 12-core systemic prostate biopsy, and the detection rate and complications were compared with those of the sextant method.
RESULTSMore positive results were obtained in detecting prostate cancer with the four regions 12-core method, and the complications were similar to those of the sextant biopsy.
CONCLUSIONThe four regions 12-core biopsy was suggested for patients suspected of prostate cancer with enlarged prostate gland above 40 ml.

Wound infection is becoming a considerable healthcare crisis due to the abuse of antibiotics and the substantial production of multidrug-resistant bacteria. Seawater immersion wounds usually become a mortal trouble because of the infection of Vibrio vulnificus. Bdellovibrio bacteriovorus, one kind of natural predatory bacteria, is recognized as a promising biological therapy against intractable bacteria. Here, we prepared a B. bacteriovorus-loaded polyvinyl alcohol/alginate hydrogel for the topical treatment of the seawater immersion wounds infected by V. vulnificus. The B. bacteriovorus-loaded hydrogel (BG) owned highly microporous structures with the mean pore size of 90 μm, improving the rapid release of B. bacteriovorus from BG when contacting the aqueous surroundings. BG showed high biosafety with no L929 cell toxicity or hemolysis. More importantly, BG exhibited excellent in vitro anti-V. vulnificus effect. The highly effective infected wound treatment effect of BG was evaluated on mouse models, revealing significant reduction of local V. vulnificus, accelerated wound contraction, and alleviated inflammation. Besides the high bacterial inhibition of BG, BG remarkably reduced inflammatory response, promoted collagen deposition, neovascularization and re-epithelization, contributing to wound healing. BG is a promising topical biological formulation against infected wounds.
