ObjectiveThis paper aims to make a research over clinical meaning of VMC with PVB and HRV.Methods22 kids who suffer from VMC with PVB and 28 kids who suffer from HRV and to compare and research their Heart Rate Variability within 24 hours.ResultsThe HRV of the VMC with PVB sufferers had decreased apparently within 24 hours( with discrepancy P ＜0.01 ).ConclusionThere exists apparent DIND in the VMC with PVB sufferers.HRV could be used to check the severness of the disease and prognosis.

This paper describes the clinical epidemiologic features, main pathogenesis, early diagnostic biomarkers and managements of septic acute kidney injury in children. It is suggested that pediatric clinicians should increase awareness of the treatment of septic acute kidney injury in children.

AIM: To investigate the role of angiotensin II (Ang II)and Ang II receptor (Ang II R) in the ischemic injury of kidney.METHODS: The expression of renal Ang II type 1 receptor (AT 1R) gene in renovascular hypertensive rats was detected by reverse transcriptase-polymerase chain reaction (RT-PCR), and levels of Ang II in the kidney and plasma were examined by radioimmunoassay.RESULTS: The study showed that the contents of Ang II in plasma and renal tissue in experimental group were increased signifiantly ( P

OBJECTIVE To conclude and analyze epidemiology,etiology,diagnostic,treatment and prognostic factors of local adult hospitalized patients with severe pneumonia.METHODS A retrospective analysis with case-control study was designed.All the medical records of consecutive patients aged ≥18 yrs with diagnosis of pneumonia from Sep 2000 to Sep 2005 in the First Affiliated Hospital of Sun Yat-sen University were searched.Contribution of the factors to prognosis was determined by multivariate analysis with Logistic regression.RESULTS In the severe community-acquired pneumonia(SCAP) subgroup,mortality was 45.0%;and in the severe hospital-acquired pneumonia(SHAP) subgroup,mortality was 54.8%.In the SCAP subgroup,there were five factors associated with prognosis on multivariate analysis: age(≥75yrs),heart failure,intubation and septic shock were risk factors;initial combined antibiotic therapy was protective factors.In the SHAP subgroup, factors associated with prognosis on multivariate analysis were heart failure,septic shock and heart rate ≥100bpm;all were risk factors.CONCLUSIONS Septic shock and heart failure are associated with mortality both in SCAP and SHAP,which suggest that severe systemic inflammatory response associated with the pulmonary infection be an important prognostic factor in the outcome of severe pneumonia.Initial appropriate antibiotic empiric therapy was important to the prognosis.

Point-of-care testing(POCT)is a kind of testing technology that uses portable testing instruments to test and quickly report the detection results at the bedside of testing object.Critically ill children need bedside examination, diagnosis and treatment in time according to the changes of their condition because of their critical condition and rapid progress.Therefore, the application of POCT in pediatric intensive care medicine has developed rapidly.Blood purification technology and extracorporeal membrane oxygenation(ECMO)are important treatment methods for critically ill children, while POCT is a necessary technology and an important link in the management of extracorporeal circulation.In this review, the application of POCT in blood purification and ECMO therapy is summarized.

DC-12 is a Bacillus strain with strong fibrinolytic activity was screened from Douchi.A novel breeding technology——whole genome shuffling was applied to enhance the production of fibrinolytic enzyme.First of all,a candidate mutant library was constructed by treating DC-12 with ultraviolet rays andhNO2,respectively.Based on studying the optimum conditions for protoplast preparation and regeneration of DC-12,multi-parental whole genome shuffling with 4 strains was conceded by protoplasts electrical fusion,then combines with the screening method of double-inactive protoplast,two strains withhigher yield of fibrinolytic enzyme were obtained effectively,which can descend stably after five generations,and their enzyme production reached 2710 IU/ml,which was increased by 4~5 fold compared with the mutants,respectively.

Objective To observe different effects of cyclic and continuous nutrition infusion on serum nutritional indicators, peripheral white blood cell counts (WBC), arterial partial pressure of oxygen (PaO2), arterial partial pressure of carbon dioxide (PaCO2) and acute physiology and chronic health evaluation Ⅲ (APACHE Ⅲ ) score in patients with mechanical ventilated respiratory failure (MVRF).Methods A cross-over and self-controlled trial was conducted in 48 patients with MVRF treated in a medical intensive care unit during December 2006 to June 2009, and continuous nutrition (group A) and cyclic nutrition (group B) were infused respectively for patients of the two groups.Serum levels of albumin (ALB), pre-albumin (PA), transferrin (TR), PaO2, PaCO2, WBC and APACHE Ⅲ score were measured for the patients with 24-hour continuous nutrition (group A) and 16-hour cyclic nutrition (group B)infusion.Effects of the two nutritional therapies were compared.Results After nutrition infusion, serum levels of ALB, PA and TR were (34±3)g/L, (196±28)mg/L and (2.1±0.3 ) g/L in group A, and (35 ±4) g/L, (198 ±25) mg/L and (2.0 ±0.4) g/L in group B, respectively; and PaO2 and PaCO2levels were (92 ± 12) mm Hg ( 1 mm Hg =0.133 kPa) and (42 ± 10) mm Hg in group A, and (91 ±9)mm Hg and (42 ± 10) mm Hg in group B, respectively.WBC and APACHE Ⅲ score were ( 11.8 ± 1.7) ×109/L and 38 ±7 in group A, and ( 12.6 ± 1.2) × 109/L and 40 ±6 in group B, respectively.Significant difference in serum levels of PA and TR was found between the two groups (PPA =0.019 and PTR =0.013),while there was no significant difference in other indictors between the two groups.Conclusions 24-hour continuous nutrition infusion for patients with MVRF can obviously improve their serum levels of PA and TR,but has no effect on serum level of ALB, PaO2, WBC and APACHE Ⅲ score in critical ill patients, as compared to those with 16-hour cyclic nutrition infusion.
