Objective To investigate the relation between positive fluid balance and the prognosis in severe sepsis patients with acute kidney injury (AKI).Methods A retrospective analysis of clinical data of 90 patients in our department was carried out.According to the final outcome,patients were divided into survival group (n =26) and non-survival group (n =64),in which the relation between patients' positive fluid balance and the prognosis was evaluated.Results (1) There was no statistically significant difference in the age and severity between survival group and non-survival group of patients with severe sepsis and consequent AKI,but the patients in non-survival group had greater volume overload.Compared with the survival group,higher mean fluid balance [(1 112.12±546.85) mLvs.(644.69±474.93) mL,P=0.00],and less urine output [(1 224.07 ± 708.79) mL vs.(2 032.36 ± 723.53) mL,P =0.00) in non-survival group.(2) There was no significant difference in mortality between early and late continuous renal replacement therapy (CRRT) during ICU care.However,the average daily fluid load in late CRRT patients was significantly greater than that in early CRRT patients [(1178.81 ±397.03) mLvs.(287.22 ± ± 433.53) mL,P =0.00] and the lung oxygenation index in late CRRT patients was significantly worse thanthat in early CRRT patients [(211.22±42.56) vs.(169.46±57.40),P=0.04] (3) The relevant variables to 28-day mortality in AKI patients with severe sepsis included CRRT treatment,oxygenation index and the average daily fluid balance ＞ 500 mL.Among them,fluid balance ＞ 500mL was an independent risk factor for AKI patients with severe sepsis.Their prognosis was worse if they had greater positive fluid balance.CRRT was the protective factor which could affect the prognosis of patients with severe sepsis complicated by AKI.Conclusions Patients with severe sepsis complicated by AKI has a high mortality.Persistent fluid overload can lead to increased mortality in patients with severe sepsis complicated by AKI.Early CRRT can reduce fluid retention in patients with renal failure and improve oxygenation index.

Objective To investgate role of TLR2 in the activation, the innate immune and inflammation of human platelets. Methods Human washed platelets were separated from healthy people(n=5) and were stimulated with different concentrations(1μg/ml, 5μg/ml, 10μg/ml) of TLR2 agonistPam3CSK4(a synthetic bacterial lipoproteins). Then the platelet aggregation rate, the expression of CD62p and TLR2 on the platelet surface were measured. Results The platelet aggregation rate were (28.32±5.67)%, (52.56±8.54)% and (76.24±11.23)%, respectively, at concentration of 1μg/ml, 5μg/mland 10μg/ml of Pam3CSK4, more than (12.83±2.43)% at 0μg/ml of it. In addition, the expression of CD62p were (18.45±2.66)%, (22.45±2.04)%, (29.53±4.08)%, respectively at above concentration of Pam3 CSK4, more than (11.20±1.67)% of CD62p at control group(P<0.01). The expression of TLR2 was not significantly increased at a lower concentration of Pam3CSK4(1μg/ml) with (16.85±6.10)% compared with(10.81±3.99)% at the control group. However, it were (21.15±9.90)% and (22.52±9.26)%, respectively, at a higher concentration(5μg/ml, 10μg/ml)more than(10.81±3.99)% at the control group(P<0.05). Conclusion Pam3CSK4 induce aggregation, activation and the up-regulation of TLR2 of platelet by stimulating TLR2 receptor of it. Thereafter, TLR2 play an important role in the innate immune of platelet.

Objective To evaluate the diagnostic value of conventional ultrasound and ultrasonic elastography (UE) in differentiating benign and malignant hepatic lesions.Methods One hundred and forty-five patients with 159 hepatic tumors were included in the study.Conventional ultrasound scan and UE were performed on each patient.Pathological results were as the golden standard.The diagnostic performance of the 2 methods were evaluated with receiver operating characteristic (ROC) curves and the interobserver agreements were analysed.Results A better interobserver agreement was achieved in UE (κ =0.325 at conventional ultrasound versus κ =0.782 at UE).The area under ROC curve of conventional ultrasound,ultrasonic elastography and the combination of both methods were 0.76,0.77 and 0.87,respectively.After the combination of the 2 methods,the sensitivity and accuracy could be enhanced significantly ( P ＜0.05).Conclusions Conventional ultrasound combined with UE may be more helpful in differentiating malignant from benign hepatic tumors.

Objective To understand the current situation of iodine deficient disorder(IDD) 10 years after achieving the stage goal of eliminating IDD in Longyan city and to evaluate the effect of prevention and treatment measures, and to provide the basis for the development of control strategies. Methods There were 7 counties in the city, and each county(city, district) was as a unit to carry out the inspection for organization and leadership,iodine salt management, monitoring and control, health education (referred to as the four management indicators)according to "The County-Level Assessment and Evaluation Implementation Detailed Rules of Realizing the Goal to Eliminate IDD in Fujian Province". According to the east, west, south, north and middle positions in each county,a village and a primary school were selected. Forty 8 to 10 year-old students in each school were randomly selected to check thyroid and among them 20 students were collected urine samples to determine urinary iodine. Nine townships were selected in the 7 counties of the city and among which 4 administrative villages were selected in each township. Eight edible salt samples from each household in each administrative village were collected to test salt iodine. Goiter was examined by palpation, the level of urinary iodine was examined by arsenic and cerium spectrophotometry, salt iodine was detected by direct titration. Results The average score of the four management indicators was 94.1 in Longyan city. The adjusted goiter rate of children aged 8 - 10 years old was 1.9%. The median of urinary iodine was 278.6 μg/L, among which less than 100 μg/L accounted for 4.57%(32/700), 100 -＜ 200 μg/L accounted for 24.00%(168/700), 200 - ＜ 300 μg/L accounted for 25.29%(177/700), and higher than 300 μg/L accounted for 46.14%(323/700). The using rate of qualified iodized salt was 98.86%. The coverage rate of iodized salt was 99.50%, the qualified rate of iodized salt was 99.35%, and the rate of non-iodized salt was 0.50%. All the indicators had reached the national standard to eliminate IDD. Conclusions After achieving the stage goal of eliminating IDD, the disease is stable and the effect of control measures are significantly. But the iodine provided has a trend of more than suitable. Therefore, it is reasonable to reduce the current salt iodine content.
