Objective To compare the effect of underwater treadmill training (UWTT), body weight support treadmill training (BWSTT) and conventional gait training (CGT) for walking ability and balance function in hemiplegic patients after stroke. Methods 43 patients were divided into CGT group (n=14), BWSTT group (n=13) and UWTT group (n=16). Based on conventional gait training, the UWTT group and BWSTT group respectively accepted UWTT and BWSTT for 4 weeks. They were assessed with Functional Ambulation Category (FAC), maximum walking speed (MWS), 6 Minute Walk Test (6MWT), and dynamic balance function and static balance function with Active Balancer before and after training. Results All the patients improved in all items after training (P<0.05), while the UWTT group improved more in the 6MWT and balance function items than the BWSTT group (P<0.05). Conclusion UWTT is more effective for hemiplegic patients after stroke in walking ability and balance function than BWSTT.

Objective To determine the optimal cut-off value of critical-care pain observation tool (CPOT) in assessing degree of pain in patients undergone craniotomy, and to determine the sensitivity and specificity of CPOT with this cut-off value. Methods A prospective observational study was conducted in Beijing Tiantan Hospital. A total of 118 patients admitted to intensive care unit (ICU) after craniotomy was consecutively enrolled during August 2014 to August 2015. CPOT and visual analogue scale (VAS) were used to assess the pain before, during and 20 minutes after the removal of central venous catheters, and the difference was compared between two scores at three time points. Receiver operating characteristic (ROC) curve was used to determine the optimal cut-off values for evaluation of the sensitivity and specificity of CPOT. Patients' complaint of pain was considered the gold-standard. Results CPOT values (inter-quartile range) before, during and after the procedure were 0 (0-3), 0 (0-6) and 0 (0-2), respectively; while VAS values were 4 (1, 6), 3 (1, 6) and 4 (1, 6), respectively. CPOT value during the procedure was significantly higher than CPOT values before and after the procedure (both P < 0.01). When the optimal cut-off value of CPOT was 1, CPOT showed the highest Youden index before, during and after the procedure (1.183, 1.515, and 1.438, respectively), and showed high specificity (all 100%) and low sensitivity (18.3% and 43.8%, respectively) when assessing the pain before and after the removal of the catheter. The sensitivity and the specificity were high when assessing the pain during the procedure, the sensitivity was 69.4%, and the specificity was 82.1%. When the optimal cut-off value of VAS was 2 before and during the procedure, and was 4 after the procedure, VAS showed the highest Youden index, 1.568, 1.452, and 1.509, respectively. VAS demonstrated high sensitivity and specificity before, during and after the procedure (sensitivity was 97.2%, 95.2% and 75.0%, respectively; specificity was 59.6%, 50.0% and 75.9%, respectively). The area under ROC curve (AUC) of CPOT before, during and after the procedure were 0.592 [95% confidence interval (95%CI) = 0.490-0.693], 0.778 (95%CI= 0.693-0.863) and 0.719 (95%CI = 0.627-0.811), respectively; the AUC of VAS before, during and after the procedure were 0.846 (95%CI = 0.771-0.920), 0.767 (95%CI = 0.681-0.854) and 0.838 (95%CI = 0.767-0.909), respectively. The AUC of VAS before and after the procedure was significantly higher than the AUC of CPOT (P < 0.001 and P = 0.006), while there was no significant difference between the AUC of VAS and CPOT during the procedure (P = 0.826). Conclusion CPOT can be used to assess the pain during painful procedure, and it shows high accuracy, but with poor evaluation effect on pain in rest.

Objective To investigate the effects of intestinal ischemia-reperfusion (I/R) on the brain in rats. Methods Sixty-four healthy male SD rats weighing 250-300 g were randomly allocated to one of 2 groups (n = 32 each): sham operation group (S) and intestinal I/R group (I/R). Intestinal I/R was produced by occlusion of superior mesenteric artery (SMA) for 90 min followed by reperfusion. Eight animals were sacrificed at each of the following time points: 2, 6, 12 and 24 h of reperfusion (T1-4) in each group. After a median sternotomyblood samples were taken from left ventricle for measurement of plasma TNF-α and IL-6 (by ELISA). Intestine and brain tissue was harvested for microscopic examination and detection of apoptosis ( by TUNEL). The cognitive function was tested using Morris water maze at 24 h. Results No abnormality was found in intestine and brain tissue in group S. Intestinal damage and neurodegeneration were detected in group I/R. Intestinal I/R significantly increased cerebral apoptosis in group I/R compared with group S. Plasma TNF-a and IL-6 concentrations were significantly higher at T1-4 in group I/R than in group S. The escape latency and swimming distance were significantly increased, while the number of crossing the platform was decreased in group I/R compared with group S. There was no significant difference in the swimming speed between the 2 groups. Conclusion Intestinal I/R can induce brain injury and lead to cognitive dysfunction. I/R-induced release of inflammatory mediators and neuronal apoptosis are involved in the underlying mechanism.

Objective To observe the effect of forearm crutches on motor function of children with spastic cerebral palsy. Methods 60 children with spastic cerebral palsy were divided into observation group (n=30) and control group (n=30). The control group accepted rou-tine rehabilitation, while the observation group were also trained to use forearm crutches. They were assessed with Gross Motor Function Measure-88 (GMFM-88) and Balancer. The way of item 70 of GMFM-88 was used to assess the mobile capability. Results The scores of GMFM-88 significantly improved in both groups after treatment (t>6.002, P<0.001), and improved more in the observation group than in the control group (t=2.317, P<0.05). The whole path length and the circumference area reduced in both groups after treatment (P<0.05), and reduced more in the observation group with the assist of the forearm crutches (P<0.01). The incidence of walking was more in the observa-tion group with the assistant of the forearm crutches (χ2=25.87, P<0.01). Conclusion Forearm crutches assistant can improve the recovery of motor function, balance and walking ability in children with spastic cerebral palsy.

OBJECTIVETo investigate the mortality rates of hepatocellular carcinoma (HCC) in Nantong,China from 1999 to 2011, in order to uncover dynamic trends and provide reasoned advice on intervention strategies to decrease HCC incidence and mortality in Nantong in the future.

METHODSVersions 10 and 9 of the WHO International Classification of Diseases (ICD-10 and ICD-9) were used to determine the number of HCC deaths in Nantong,China for the study's range of years. Thex2 test was applied to compare the HCC mortality rates according to sex and age. The Grey system GM(1,1) model was used to predict the next-5-year HCC mortality for Nantong.

RESULTSAnalysis of the standardized mortality in Nantong showed a slight decreasing trend from 1999 to 2011 (x2=57 545.98, P less than 0.001),with males showing a steeper decrease than females. The total mortality of HCC during these years was 53.41 per 100,000 people,with mortality among males being significantly higher than that among females (80.81 per 100,000 people vs. 26.94 per 100,000 people; x2=13 625.42, P less than 0.001). In general, HCC mortality increased with increase in age (general trend:x2=57 545.98, P less than 0.001; male trend: x2=39 878.8, P less than 0.001; female trend: x2=20 105.3, P less than 0.001). However,HCC mortality increased significantly in women after the age of 40 and in men after the age of 35. The GM(1,1) equation was: Yt=-1265.28e(-0.0375t)+1315.5, which predicted that the HCC mortality will decrease to 25.56 per 100,000 people in 2016.

CONCLUSIONAlthough HCC mortality generally decreased from 1999 to 2011, the rate remained high. Public health intervention strategies may be more effective if they focus on males over the age of 35 and females over the age of 40.
