Method ELISA was used to test cord blood EPO and ET-1 in 54 high risk neonates as subjects and 14 healthy neonates as controls.Results The cord blood EPO levels in amniotic fluids turbid Ⅲ degree group and group eclampsia/pre - eclampsia were higher than those in control group (t= 4.0842,3 680 allP

Objective To explore the difference of pathogenesis between chronic hepatitis B (CHB) and asymptomatic hepatitis B virus(HBV) carriers(ASCs) in children.Methods Subtracted libraries was constructed by suppression subtractive hybridization (SSH) from peripheral blood mononuclear cell (PBMC) of two groups, beta-2-microglobulin (?_2-MG) was screened as one of differentially expressed genes. Serum was collected from children with CHB and ASCs, the differential expression of ?_2-MG was confirmed by enzyme immunoassay.Results Subtractive libraries were constructed successfully, the differentially expression of ?_2-MG and lactroferrin were up-regulated in CHB children.And the differentially expression of ?_2-MG on the level of protein was confirmed.Conclusion The up-regulation of ?_2-MG in CHB children is involved in the pathogenesis mechanisms.

Objective To evaluate the effect of combination transfer pump and single blood pump to 32 cases of renal failure patient who need blood purification therapy.Methods The combination transfer pump and single blood pump were used.According to the clinical requirement,the parameters of transfer pump were set such as therapy time,replacement liquid flow rate,dialysate flow rate,temperature of warmer and filtrate flow rate,etc.Results 32 patients with varying degrees of illness have been alleviated.Patients' acute left heart failure,water and electrolyte turbulences,acid intoxication and azotemia caused by liquid retention were corrected,which ensured a role for further treatment.Conclusion It is the functions of adjustable time and transfusion volume that are used in the combination transfer pump,the task of which is accomplished by several transfer pumps together.This method is easy to implement and can meet the clinical requirement largely without special CBP instrument.

Objective To explore the influence of different positive end-expiratory pressure (PEEP) levels on cerebral blood flow (CBF) and cerebrovascular autoregulation in patients with acute respiratory distress syndrome (ARDS).Methods A prospective study was conducted.Moderate or severe ARDS patients admitted to Department of Critical Care Medicine of Jiangxi Provincial People's Hospital from January 1st,2013 to October 1st,2013 were enrolled.The changes in hemodynamics,respiratory mechanics and gas exchange under different levels of PEEP were observed.CBF velocity of middle cerebral artery (MCA) was measured using transcranial Doppler (TCD),and breath-holding index (BHI) was also calculated.Results 35 patients with ARDS were included.The oxygenation index (OI),peak inspiratory pressure (PIP),plat pressure (Pplat) and central venous pressure (CVP) were markedly elevated [OI (mmHg,1 mmHg=0.133 kPa):324.7± 117.2 vs.173.4± 95.8,t=5.913,P=0.000; PIP (cmH2O):34.7 ± 9.1 vs.26.1 ± 7.9,t=4.222,P=0.000; Pplat (cmH2O):30.5 ± 8.4 vs.22.2 ± 7.1,t=4.465,P=0.000; CVP (mmHg):12.1 ± 3.5 vs.8.8 ± 2.2,t=4.723,P=0.000] when PEEP was increased from (6.4 ± 1.0) cmH2O to (14.5-± 2.0) cmH2O (1 cmH2O=0.098 kPa).But no significant difference in the heart rate (beats/min:85.5 ± 19.1 vs.82.7 ± 17.3,t=0.643,P=0.523),mean arterial pressure (mmHg:73.5 ± 12.4 vs.76.4 ± 15.1,t=0.878,P=0.383) and CBF velocity of MCA [peak systohc flow velocity (Vmax,cm/s):91.26 ± 17.57 vs.96.64 ± 18.71,t=1.240,P=0.219; diastolic flow velocity (Vmin,cm/s) 31.54 ±7.71 vs.33.87 ±8.53,t=1.199,P=0.235; mean velocity (Vmean,cm/s) 51.19 ± 12.05 vs.54.27 ± 13.36,t=1.013,P=0.315] was found.18 patients with BHI＜0.1 at baseline demonstrated that cerebral vasomotor reactivity was poor.BHI was slightly decreased with increase in PEEP (0.78 ± 0.16 vs.0.86 ± 0.19,t=1.905,P=0.061).Conclusions Some of moderate or severe ARDS patients without central nervous system disease have independent of preexisting cerebral autoregulation impairment.However,independent of preexisting cerebral autoregulation may not further be impaired when a high PEEP was chosen.

Objective To approach the effect of different vasopressor on hemodynamics, volume responsiveness, fluid volume balance, renal function and prognosis in patients with acute respiratory distress syndrome (ARDS) complicated with septic shock.Methods A prospective single-blind randomized controlled trial was conducted. ARDS patients with septic shock admitted to the Department of Critical Care Medicine of Jiangxi Provincial People's Hospital from January 1st, 2015 to May 1st, 2016 were enrolled. The patients satisfied ARDS Berlin diagnostic criteria, over 15 years old, needing vasopressor after fluid resuscitation were enrolled. The patients were divided into norepinephrine group (NE group) and terlipressin group (TP group) by randomise number table derived by computer. Patients in TP group were given terlipressin (0.01-0.04 U/min) with an intravenous pump, while those of NE group were given norepinephrine (> 1μg/min) with an intravenous pump, and the target mean arterial pressure (MAP) was maintained at 65-75 mmHg (1 mmHg = 0.133 kPa). Hemodynamics and extravascular lung water index (EVLWI) were monitored by pulse indicator continuous cardiac output (PiCCO). The volume responsiveness of patient was evaluated by passive leg raising (PLR) test, and cardiac index (CI) change (ΔCI ≥ 10%) served as positive volume responsiveness. The differences in hemodynamics, EVLWI, oxygenation index (OI), lactate clearance rate (LCR), rate of positive volume responsiveness, urinary output, fluid volume balance, renal function, and prognostic indicators were compared between the two groups.Results Fifty-seven patients with ARDS complicated with septic shock were enrolled, with 26 patients in NE group, and 31 patients in TP group, thebaseline data in both groups was balanced with comparability. Compare with NE group, 48-hour and 72-hour heart rate (HR) in TP group was significantly slowed (bpm: 82.1±6.8 vs. 87.6±7.4, 81.3±6.1 vs. 85.6±8.3, bothP < 0.05), 72-hour central venous pressure (CVP) was significantly decreased (mmHg: 9.4±2.6 vs. 10.9±3.0,P < 0.05), but no significant difference was found in HR, MAP, CVP, CI, EVLWI, OI and LCR at other time points between the two groups. 48-hour and 72-hour positive volume responsiveness rate in TP group were significantly increased as compared with those of NE group (74.2% vs. 46.2%, 64.5% vs. 38.5%, both P < 0.05), urinary output on the 2nd day (mL/24 h: 2342.8±704.1 vs. 1944.6±684.3) and fluid volume balance (mL: -319.7±54.8 vs. -169.6±27.2) were significantly decreased (bothP < 0.05). There was no significant difference in positive volume responsiveness rate, urine output, fluid volume balance, and the level of serum creatinine at other time points between the two groups. There was no statistically significant difference in the following features between TP group and NE group: duration of mechanical ventilation (days: 8.41±2.97 vs. 9.67±3.56), length of intensive care unit (ICU) stay (days: 12.84±4.47 vs. 14.77±5.01), total length of hospital stay (days: 19.34±7.37 vs. 21.07±8.41), and 28-day mortality (29.0% vs. 30.8%, allP > 0.05).Conclusions Compared with norepinephrine, terlipressin for ARDS patients with septic shock is more conducive to restrict fluid load, improve the renal perfusion and increase urine output. However, in both groups therewas no significant difference in the efficiency of stabilizing hemodynamics, shortening the duration of mechanical ventilation, reducing ICU or hospital days and decreasing 28-day mortality.

Racemic (±)-F18 (10-chloromethyl-11-demethyl-12-oxo-calanolide A), an analog of nature product (+)-calanolide A, is a new anti-HIV-1 nonnucleoside reverse transcript inhibitor (NNRTI). A successful enantioseparation of (±)-F18 offering (R)-F18 and (S)-F18 was achieved by a chiral stationary phase prepared HPLC. Their absolute configurations were determined by measurement of their electronic circular dichroisms combined with modem quantum-chemical calculations. Further investigation revealed that (R)-F18 and (S)-F18 shared a similar anti-HIV activities, however, (R)-F18 was more potent than (S)-F18 against wild-type virus, K101E mutation and P225H mutation pseudoviruses.
