Objective To investigate the clinical effects of the pulse indicator continuous cardiac output (PiCCO) in goal-optimized fluid management on patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with respiratory failure.Methods A total of 71 AECOPD patients with respiratory failure who were hospitalized in department of Critical Care Medicine in our hospital were selected from October 2010 to September 2013.The PiCCOtechnology was applied to monitor intrathoracic blood volume index (ITBI) and extravascular lung water index (ELWI).We compared the relationship of ELWI with ITBI and oxygenation index,and a simple correlation analysis was used for statistical analysis.Results A significantly negative correlation was found between ELWl and oxygenation index (r=-0.743,P＜0.01).ELWI =14 ml/kg was defined as the cutoff value for the subgroup analysis.A negative correlation still was found between ELWI and oxygenation index in the subgroup with ELWI ＜ 14 ml/kg,but it had no significant difference (r=-0.533,P=0.080),while a significantly negative correlation was found in the subgroup with ELWI≥14 ml/kg (r=-0.961,P＜0.01).There was no significant correlation between ELWI and ITBI (r=0.477,P=0.072).ITBI=1 000 ml/m2 was defined as the cutoff value for the subgroup analysis.There is no significant correlation between ELWI and ITBI in the subgroup with ITBI＜1 000 ml/m2(r=0.338,P=0.116),but in the subgroup with ITBI≥1 000 ml/m2,a significantly positive correlation between ELWI and ITBI was found (r=0.677,P＜ 0.01).Conclusions The results suggest that when ELWI is higher than 14 ml/kg,ELWI becomes an important influencing factor for oxygenation,which can be decreased to improve oxygenation in patients with AECOPD,and when ITBI≥ 1 000 ml/m2,ITBI can be reduced by decreasing ELWI.PiCCO has an important clinical significance on a goal-optimized fluid management in AECOPD patients with respiratory failure.

Objective To explore the effect of early goal-directed therapy (EGDT) according to pulse indicated continuous cardiac output (PiCCO) on septic shock patients.Methods Eighty-two septic shock patients in Subei People's Hospital of Jiangsu Province from January 2009 to December 2012 were enrolled and randomly divided into two groups using a random number table,standard surviving sepsis bundle group (n=40) and modified surviving sepsis bundles group (n =42).The patients received the standard EGDT bundles in standard surviving sepsis bundle group.PiCCO catheter was placed in modified surviving sepsis bundles group.Fluid resuscitation was guided by intrathoracic blood volume index (ITBVI) with the aim of 850-1 000 mL/m2.Dobutamine was used to improve the heart function according to left ventricular contractile index (dPmax) and stroke volume index (SVI).The mean arterial blood pressure (MAP) was maintained 65 mmHg (1 mmHg=0.133 kPa) or above with norepinephrine.Extra-vascular lung water was monitored for the titration of liquid and diuretics.The acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score,sequential organ failure assessment (SOFA) score,the number of patients needed vasopressor,serum procalcitonin (PCT),lactic acid and lactate extraction ratio,the amount of fluid resuscitation,duration of mechanical ventilation,duration of intensive care unit (ICU) stay,hospital mortality were recorded in both groups.Results After treatment,the APACHE Ⅱ score,SOFA score and the number of patients needed vasopressor were gradually reduced in both groups,and those in modified surviving sepsis bundle group were significantly lower than those of standard sepsis bundle group at 72 hours (APACHE Ⅱ score:13.1 ± 6.5 vs.20.9 ± 7.5,SOFA score:8.8 ± 4.3 vs.14.6 ± 4.9,the number of patients needed vasopressor:8 vs.17,all P＜0.05).Arterial blood lactate clearance rate was gradually increased after treatment in both groups.Lactate clearance rate in modified surviving sepsis bundle group was significantly higher than that of standard surviving sepsis bundle group [6 hours:(18.2 ± 8.3)％ vs.(10.8 ± 7.5)％,t=-6.036,P=0.001 ; 12 hours:(22.6 ± 7.3)％ vs.(12.4 ± 8.1)％,t=-4.536,P=0.001 ; 24 hours:(27.8 ± 5.6)％ vs.(16.4 ± 9.5)％,t=-5.882,P=0.000].The amount of fluid resuscitation within 6 hours in modified surviving sepsis bundle group increased significantly compared with standard surviving sepsis bundle group (mL:3 608 ± 715 vs.2 809 ± 795,t=-3.865,P=0.033).The amount of fluid resuscitation within 24,48 and 72 hours in modified surviving sepsis bundle group was significantly less than that of standard modified surviving sepsis bundle group with the nadir at 72 hours (mL:918 ± 351 vs.1 805 ± 420,t=5.907,P=0.037).Duration of mechanical ventilation (hours:98.4 ± 20.3 vs.143.3 ± 29.6,t=9.766,P=0.001) and ICU stay (days:7.1 ± 3.1 vs.9.5 ± 2.5,t=2.993,P=0.004) were significantly reduced in modified surviving sepsis bundle group compared with standard surviving sepsis bundle group.The hospital mortality in modified surviving sepsis bundle group was slightly lower than that in standard surviving sepsis bundle group [16.7％(7/42)比 17.5％(7/40),x2=0.010,P=0.920].Conclusions Modified surviving sepsis bundle treatment according PiCCO can reduce the severity of disease in patients with septic shock,can make more accurately guide fluid resuscitation,and can reduce lung water and duration of mechanical ventilation and ICU stay.It has great clinical significance.

Objective To evaluate the compliance of sepsis bundles and its impact on the mortality rate in patients with sepsis shock.Methods Fifty-eight adult patients with sepsis shock admitted in the intensive care units from January to December 2007 were enrolled in the study,and the compliance with the 6-h bundle was analyzed.Age,gender,sites of infection,acute physiology and chronic health evaluation II (APACHE II)score,duration of mechanical ventilation,ICU stay and the mortality rate were compared between patients completed 6-h bundles and those not completed 6-h bundles.Results Compliance with the 6-h bundle was obtained in 22 out of 58 patients(37.9%).Patients receiving bundle care had shorter duration of mechanical ventilation and shorter length of ICU stay than non-bundle patients(t=-2.225 and -3.702,P=0.037 and 0.001,respectively),and the mortality rate in 6-h bundle patients was also lower (X2=10.236,P=0.000).Conclusion The application of 6-h bundle care can reduce the mortality rate of the patients with sepsis shock.and the compliance should be improved.

Objective To review the treatment of repair gastroschisis with autogenous umbilical cord and evaluate its effect. Methods Thirty newborns who underwent the repair gastroschisis with autogenous umbilical cord between August 1992 to October 2007, 26 cases survived under observed and followed-up, observing physical growth, intelligence measuring and whether the area of operated in abdomen need staged repair or not. Compared with 15 cases who underwent traditional operation method at the same time. Results Two cases died, 2 cases abandoned, and 26 ease received survive (survive rate 86.7%)and their growth was well in 26 cases. But in those 15 cases who underwent traditional operation method, 5 cases survived (survive rate 33.3%). There were significant difference in the survive rate, the mean operative time and postoperative hospital stay time between the two operation methods (P <0.05).Conclusion The material is adopted easily in the operation, autogenous umbilical cord is elastic tissue and no toxicity, it can relax the abdominal press effectively after the operation, the survive rate is high.

Using the Gram-positive Staphylococcus aureus as the indictor bacterium,fourteen antibacterial strains were initially obtained by the bilayer-media screening method from the raw milk samples,and one isolate was found to exhibit the higher antibacterial activity against the indicator. This isolate was further studied on its individual and cultural morphology features,partial physiological and biochemical reaction activities,G+C content,the sequence features of the 16S rDNA and the species-specific N-acetylmuraminidase gene(acmA) ,consequently,it was identified as the Lactococcus lactis subsp. lactis strain,named as MB191. An evaluation of the antimicrobial spectra of MB191 was subsequently performed,it showed the remarkable activities against not only the tested Gram-positive bacteria,but also several Gram-negative bacteria including Pseudomonas syringae and P. fluorescens,as well as the yeast Debaryomyces hansenii,which was a distinctive feature that was not reported prior to this study.

Objective To study the clinicopathologieal features and expression of cyclin D1 and p53 in epithelial ovarian tumors,and to investigate the correlation between pathogenesis of ovarian cancer and epithelial borderline tumors.Methods Fifty four cases of ovarian borderline tumors and 45 cases of ovarian carcinomas from the People's Hospital,Peking University were reviewed retrospectively.The clinical data and pathological findings were analyzed.Immunohistochemical study of cyclin D1 and p53 was performed in all 99 cases.Results(1)In borderline tumors,the age of patients ranged from 14-82 (mean age=42.5)years.International Federation of Gynecology and Obstetrics(FIGO)stage of borderline tumors was stage Ⅰ in 48 cases,stage Ⅱ in 3 cases,and stage Ⅲ in 3 cases.In ovarian carcinomas,the age of patients ranged from 26-80(mean age=53.5)years.FIGO stage of carcinoma was stage Ⅰ in 6 cases, stage Ⅱ in 8 cases,stage Ⅲ in 26 cases,and stage Ⅳ in 5 cases.In follow-up of 54 cases with borderline tumors the 5-year survival rate was 98% and of 45 cases with carcinomas a 5-year survival rate of 51% was noted.(2)In 54 cases of borderline tumors,mucinous types accounted for 56%(30/54)and serous types accounted for 30%(16/54).There were 5 cases with micropapillary pattern,3 cases with peritoneal implants,3 cases with lymph node involvement,6 cases with microinvasion,one case with intraepithelial carcinoma,and one case with mural nodules.In 45 cases of carcinomas,serous carcinoma was the most (49%,22/45).The remainder included 3 cases of mucinous types,8 cases of endometrioid types,6 cases of transitional cell types,3 cases of mixed phenotype and 3 cases of undifferentiated types.(3) Overexpression of cyclin D1 and p53 was observed in 31%(14/45)and 56%(25/45)of ovarian carcinomas, respectively.There was a significant association between p53 overexpression and tumor grade.In the borderline tumor group,69%(37/54)had overexpression of cyelin D1 and 6%(3/54)had overexpression of p53.There were significant differences in expression of cyclin D1 and p53 between conventional serous borderline tumors and high-grade serous carcinomas(cyclin D1:91% vs 26%;p53:0 vs 58%).However, micropapillary serous borderline tumors and low-grade serous carcinomas showed remarkably similar expression of cyelin D1 and p53.Conclusions Epithelial ovarian borderline tumors are distinct from ovarian cancer in clinical progress and prognosis,and histological types.Overexpression of cyclin D1 is common in ovarian borderline tumors and low grade carcinomas.And overexpression of p53 is more common in high grade ovarian carcinomas.Conventional serous borderline tumors are distinct from high-grade serous carcinomas in pathogenesis.Micropapillary serous borderline ovarian tumors may be closely related to low grade serous carcinomas.
