Objective To explore the changes and influencing factors of serum NT-proBNP level in aged patients with severe brain dysfunction in acute phase, and the corresponding clinical significance. Methods The serum NT-proBNP and cTn-I levels of patients with severe brain dysfunction at day 1, 3, 5 and 7 were measured respectively. The correlation between acute neurological dysfunction caused by brain dysfunction and serum NT-proBNP and cTn-I levels were analyzed, and the impact on prognosis was explored. Results The serum NT-proBNP levels were significantly higher in death group at day 3[(759±341)ng/L], 5[(1980±839)ng/L] and 7[(2490±1862)ng/L] than in survival group[(594±612)ng/L,(733±424)ng/L,(315±346)ng/L]. Serum NT-proBNP and cTnI levels were associated with progressive cerebral edema in both groups. Location of early intracranial lesions was significantly different between two groups. Death group had higher ratio of intracranial lesions in basal ganglia and brainstem than did survival group. High serum NT-proBNP level after day 7 suggested poor prognosis. Serum NT-proBNP level was not associated with serum cTn-I level. Conclusions Progressively increased serum NT-proBNP level in aged patients with severe brain dysfunction in acute phase suggests poor prognosis. The increased degree of serum NT-proBNP in aged patients with severe brain dysfunction in acute phase is associated with the location of intracranial lesions.

Results Compared with model group , the hepatocyte viability in SAA high or low dose group and Vit E group were significantly increased (P <0.01), and the activities of ALT, AST and LDH in SAA high dose group were significantly lowed ( P <0.01 ) .The activity of SOD in SAA high dose group and Vit E group was significantly increased ( P <0.05), while MDA content was decreased (P <0.05).Vivo test showed that the levels of serum LN and HA in SAAhigh dose group were significant lower than those of hepatic fibrosis rat model group (P <0.05).Moreover, the activity of SOD in SAA high or low dose group was significantly increased (P <0.05, P <0.01), while MDA content was lowed (P <0.05, P <0.01), and can improve the pathological of liver tissues .Conclusions SAA injection can anti-lipid peroxidation and thereby protect hepatocyte and reduce hepatic fibrosis .

Objective To investigate the effects of enteral nutrition with galactooligosaccharides (GOS) on serum inflammatory cytokines in rats with severe acute pancreatitis (SAP). Methods SD rats were randomly divided into sham operation control group, SAP with enteral nutrition (EN) group and SAP with EN supplemented with GOS (GOS-EN) group, and each group was divided into 4 d and 7 d subgroups according to the time that animals were sacrificed (n=8 in each subgroup). Rat SAP models were established by injection of 38 g/L sodium taurocholate beneath the pancreatic capsule. The serum amylase, inflammatory cytokines TNF-α, IL-2 and IL-10 were detected. Results At each time point, the levels of serum amylase in all SAP groups were significantly higher than those in sham operation control group (P < 0.01), and the levels in GOS-EN group were significantly lower than those in EN group (P < 0.01). The levels of serum TNF-α and IL-10 in all SAP groups were significantly higher than those in sham operation control group (P < 0.01), while the levels of IL-2 in all SAP groups were significantly lower than those in sham operation control group. The levels of TNF-α in GOS-EN group were significantly lower than those in EN group (P <0.05), while the levels of IL-2 and IL-10 and the ratio of IL-10/TNF-α were significantly higher than those in GOS-EN group (P < 0.05). Conclusion Early EN supplemented with GOS could modulate the balance of pro- and anti-inflammatory response.

Objective To investigate the development trend of drinking-water-borne endemic fluorosis in Jiangsu Province,and to provide the basis for further prevention and treatment of the disease.Methods In 2009,eight major counties were chosen,and in each county all diseased villages were classified into light,moderate and severe disease types according to water fluorine content based on historical data,and one village was chosen from each type.In monitoring villages with improved water,one source water and three tap water samples were collected,respectively.Five water samples were collected in water unimproved monitoring villages according to water well locations of the east,the west,the south,the north and the center.The fluorine content in water was determined according to the Standard Testing Methods for Drinking Water (GB/T 5750-2006).Children aged 8 to 12 were examined for dental fluorosis by Dean method.Residents over the age of 16 were examined for clinical osteofluorosis,and two monitoring counties were chosen,then one village was respectively chosen in each county,and clinically diagnosed patients with skeletal fluorosis were examined again by X-ray.Both clinical and X-ray diagnosis were on the basis of Diagnostic Criteria of Endemic Skeletal Fluorosis (WS 192-2008).Urine samples of 30 children aged 8 to 12 and of 20 adults over the age of 16 were randomly collected and urinary fluoride was determined by F-ion selective electrode method(WS/T 89-1996).Results Of all the 24 villages of 8 counties,20 villages were water improved,and water-improvedprojects ran normally in 18 villages,while scrapped in the rest 2 villages.One hundred and two samples were tested,and the mean of water fluoride in water-improved villages was 1.10 mg/L,while in water unimproved villages and villages with water improved projects scrapped was 1.90 mg/L.The prevalence of dental fluorosis was 42.51％(854/2009).The prevalence of clinical skeletal fluorosis was 23.23％ (2024/8713) and the X-ray detection rate was 32.00％ (24/75).Six hundred and sixty-four urine samples of children were determined,and geometric mean of urinary fluorine was 1.59 mg/L,while 370 adult urine samples were determined,and geometric mean of urinary fluorine was 2.20 mg/L.Conclusions Endemic fluorosis in Jiangsu Province has not been fully controlled and there are signs of recovery.We must pay attention to water improvement measures to reduce fluoride and the management and maintenance of water improvement projects,and further strengthen the prevention and control of endemic fluorosis.
