ABSTRACT
The anticipatory postural adjustments can be more precise in reflecting the ability of posture control,which associate with two kinds of neuromuscular model.Anticipatory postural adjustments disorders are found in stroke patients with hemiplegia,such as delay of muscle activation time,decrease of muscle activation,degradation of muscle recruitment order and reduction of adaptability.
ABSTRACT
Objective To determine the level and clinical significance of 5-hydroxytryptamine (5-HT) and intestinal fatty acid binding protein (iFABP) in patients of severe acute pancreatitis (SAP) with intestinal dysfunction. Methods The serum and urine in 42 cases of SAP with intestinal dysfunction were collected at day 1, 3 and 7 after admission, respectively. The numbers of bowel sounds were recorded. 20 health subjects were selected as the control. Results The numbers of bowel sounds in health subjects were 5.6 ± 2.3/min. The numbers of bowel sounds in SAP patients at day 1,3 and 7 were 2.3 ± 0.7/min, 1.7 ± 0.2/min and 3.1 ± 1.1/min, respectively;which were significantly lower than that in the control group (P < 0.01). The level of 5-HT in the control group was(86.7 ± 9.5)ng/ml, while the levels of 5-HT in the SAP patients at day 1, 3 and 7 were (112.0 ± 17.8) ng/ml, (130.5 ± 19.7) ng/ml, (107.9 ± 16.3) ng/ml. The level of urine iFABP in the control group was (90.5 ± 19.8) pg/ml, while the levels of urine iFABP in the SAP patients were (1250.2 ± 425.3) pg/ml, (1586.9 ± 523.4) pg/ml, (1154.6 ± 394.0) pg/ml. The levels of 5-HT and urine iFABP in the SAP patients all were significantly higher than those in the control group (P <0.01). The levels of 5-HT and urine iFABP in the SAP patients at day 3 were significantly higher than those in the day 1 and day 7, while there was no significant difference between the two groups. Conclusions Determination of serum 5-HT and urine iFABP in patients with early SAP could effectively evaluate the intestinal function, and it may have potential clinical significance.
ABSTRACT
Objective To investigate the effect of Da-Cheng-Qi decoction on enteric functional disturbance in rats with acute experimental pancreatitis and its potential mechanism. Methods Seventy-two SD rats were randomly divided into sham operation group, acute pancreatitis (AP) group and Da-Cheng-Qi decoction treated group with 24 each. The AP model was induced by retrograde injection of sodium taurocholate (0.1 ml/100 g) into bitiopancreatic duet. Before modeling, the rats in treatment group received Da-Cheng-Qi decoction (2 g/100 g), and the rats in other two groups received 0.9% NaCl solution. The rats were sacrificed at 3, 6 and 12 hours with 8 each, and the blood samples were taken for detecting the level of amylase and the contents of 5-hydroxytryptamine (5-HT) by enzyme-linked immunosorbent assay. The colonic tissues 10 cm apart from trans-ligament incluing jejunum, terminal ileum and sigmoid colon were collected for examining the expressions of 5-HT_3 and 5-HT_4mRNA and proteins by RT-PCR and Western blotting respectively. Results ① The levels of serum amylase and 5-HT in AP group and treatment group were significantly higher than those in sham operation group (P<0. 01), but they were lower in treatment group than in AP group at each time points (P<0. 05). The level of 5-HT was increased in the initial stage and then decreased gradually both in AP group and treatment group. ③ The expressions of 5-HT_3 and 5-HT_4 mRNA and proteins were significantly decreased in the jejunum, terminal ileum and sigmoid colon in AP group compared with sham operation group (P<0. 01). Whereas the expressions of 5-HT_3 mRNA and protein,but not 5-HT_4, were increased in the treatment group in comparison with AP group (P<0.05). Conclusions The level of 5-HT is significantly increased in acute pancreatitis, but its receptors (5-HT_3 and 5-HT_4) are decreased, which may induce enteric functional disturbance. The Da-Cheng-Qi decoction may improve enteric dynamic failure by increasing the expression of 5-HT_4 and may be a choice for treatment of acute pancreatitis with enteric dynamic failure
ABSTRACT
Objective To investigate the therapeutic effect of Da-Cheng-Qi Decoction on gut dysfunction in patients with severe acute pancreatitis (SAP). Methods Forty-eight SAP patients complicated with gut dysfunction were randomly divided into two groups according to the number of admission, which were treatment group and control group. The therapy in t reatment group was Da-Cheng-Qi Decoction infusion through gastric tube (one paste/day, b. i. d), however the therapy of control group was normal saline infusion through gastric tube (the amount was the same as the former, b. i. d), and other management in the two groups was similar. The first passage of gas by anus and defecation after treatment was observed. Serum amylase, C-reactive protein (CRP), tumor necrosis factor (TNF)-α, interleukin (IL)-6 were examined before and one week after treatment;complications and mortality were compared between the two groups. Results The first passage of gas by anus and defecation in the treatment group was ( 12.3 ± 5.7 ) h and ( 24.8 ± 11.2 ) h, respectively, and shorter than ( 22. 1 ± 9.7 ) h and 46.2 ± 17.4) h of control group ( P <0.01) ;the numerical values of serum amylase, CRP, TNF-α and IL-6 one week after treatment were ( 120.3 ± 35.8 ) U/L, ( 10.8 ±2.0) ng/ml, (36.3 ± 5.8) U/L and (4.8 ± 1.0) U/L, which were significantly decreased when compared with the values before treatment, and these values were significantly lower than (267.2 ± 78.9 )U/L, ( 19.5 ± 2.7 ) ng/ml, (80.1 ± 9.0) U/L, ( 10.5 ± 1.2 ) U/L of the control group ( P < 0.05 ). The total complications and mortality of treatment group was 12.5% and 4.4%, respectively, which were significantly lower than those in the control group (37.5% and 25%, P <0.05). Conclusions Treatment with Da-Cheng-Qi Decoction in SAPpatients complicated with gut dysfunction was effective to reverse gut dysfunction and reduce total complications and mortality.

ABSTRACT
<p><b>OBJECTIVE</b>The expressions of caspase-1 and cytokines activated by caspase-1 are associated with the pathophysiology of many diseases for its proinflammatory and proapototic peculiarity. However its relationship to brain injury of developing rats following recurrent seizures has not yet been identified. This study aimed to investigate the role of caspase-1 and cytokines activated by caspase-1 in brain injury of developing rats following recurrent seizures.</p><p><b>METHODS</b>A total of 96 postnatal 20 day Sprague-Dawley rats were randomly assigned into Control and Seizure groups. Seizures were induced in the Seizure group by flurothyl inhalation daily for six days. Brain tissues were sampled at 6 hrs, and at 1, 3, and 7 days after last seizure. The expressions of caspase-1, interleukin (IL)-18 and IL-1beta mRNA in the cerebral cortex were detected by RT-PCR. The water content of the brain and the pathological changes of cortex nerve cells were observed. Brain injury was evaluated using a semiquantitative neuropathological scoring system.</p><p><b>RESULTS</b>The levels of caspase-1 and IL-18 mRNA in the cerebral cortex of the Seizure group were obviously higher than those in the Control group at 6 hrs, and at 1, 3, and 7 days after seizure (P < 0.05 or P < 0.01). The expression of IL-1beta mRNA in the Seizure group exhibited a biphasic pattern: increased significantly at 6 hrs, and at 1 and 7 days post-seizure (P < 0.01), but was not significantly different from the Control group at 3 days post-seizure. Edema, degeneration and necrosis of nerve cells in cerebral cortex, accompanying by inflammatory cell infiltration and apoptosis of nerve cells, were observed under a light microscope in the Seizure group after recurrent seizures. The water content of the brain in the Seizure group increased significantly compared with that in the Control group at 6 hrs, and at 1 and 3 days after recurrent seizures (P < 0.01). The Seizure group had significantly higher neuropathological scores than the Control group at each time point (P < 0.01).</p><p><b>CONCLUSIONS</b>Caspase-1 and cytokines activated by caspase-1 play an important role in the developing brain injury after recurrent seizures.</p>

<p><b>OBJECTIVE</b>This study investigated the effects of flurothyl-induced neonatal recurrent seizures on gamma-aminobutyric acid B1 receptor (GABAB1R) expression in neonatal and adult rat brain, and explored the possible relationship between the alterations of GABAB1R in mature brain and the changes of spatial memory and seizure susceptibility in adult rats.</p><p><b>METHODS</b>Forty-eight postnatal day (P) 7 Sprague-Dawley rats were randomly assigned into two groups: Control and Seizure group (n=24 each). Seizures were induced by inhalant flurothyl daily for six consecutive days in rat pups from the Seizure group. Twelve rats selected randomly in each group were sacrificed on the 7th day after the last seizure for detecting the expressions of GABAB1R mRNA and protein in cerebral cortex and hippocampus by reverse transcription-polymerase chain reaction (RT-PCR) and immuno-histochemistry method. The spatial memory was tested by using the Morris water maze task during P61 to P64 and the seizure threshold was measured at P75 following intraperitoneal injection of pentylenetetrazol ( PTZ ) in the remaining rats. The rats were then sacrificed for detecting the expressions of GABAB1R mRNA and protein in cerebral cortex and hippocampus.</p><p><b>RESULTS</b>The expressions of GABAB1R mRNA and protein in the cerebral cortex on the 7th day after the last seizure and at P75 decreased significantly in the Seizure group when compared with the Control group (P < 0.05). The GABAB1R protein expression in the dentate gyrus on the 7th day after the last seizure in the Seizure group was significantly lower than that in the Control group (P < 0.05), but the GABAB1R mRNA expression in the hippocampus was not different from that in the Control group. There were no significant differences in the expressions of GABAB1R mRNA and protein in the hippocampus between the two groups at P75. The escape latencies in water maze of the rats in the Seizure group at P64 were significantly longer than those in the Control group (98,533.8 +/- 27,205.4 ms vs 46,723.3 +/- 40,666.5 ms; P <0.05). There were no differences in the seizure threshold between the two groups.</p><p><b>CONCLUSIONS</b>The expressions of GABAB1R mRNA and protein in the cerebral cortex and hippocampus of neonatal rats with recurrent seizures decreased significantly, suggesting the changes of GABAB1R may be related to acute brain injury following neonatal recurrent seizures and the memory deficit in adult rats caused by neonatal recurrent seizures.</p>
