This article was aimed to study the intestinal absorption about main active ingredients of pectolinarin and pectolinarigenin in Carboned Cirsium japonicum DC. The absorption rate and absorption rate constant were taken as indicators. The intestinal absorption of pectolinarin and pectolinarigenin were compared by everted rat intestinal sac method among different parts of the small intestine. The results showed that the absorption rate constant of pectoli-narin among duodenum, jejunum, ileum and colon parts were 0.505 1 ± 0.192 7, 0.936 0 ± 0.187 2, 0.732 0 ±0.133 5, 0.251 3 ± 0.027 6 (μg·h-1·cm-2). The absorption rate constant of pectolinarigenin among the duodenum, je-junum, ileum and colon were 0.059 1 ±0.008 3, 0.093 3 ±0.029 2, 0.112 3 ± 0.035 6, 0.029 4 ± 0.009 1 (μg·h-1·cm-2). It was concluded that the absorption of both ingredients increased over time. The absorption of both ingredi-ents in the jejunum and ileum was higher than other parts of the small intestine. The absorption rate of pectolinarin in the entire small intestine was much higher than the absorption rate of pectolinarigenin.

Objective To explore the effects of the neotype hand-arm sling on shoulder subluxation and transferring movement in hemiplegic stroke patients.Methods Thirty hemiplegic stroke survivors with shoulder subluxation and poor elbow flexor muscle tone (＜2 on the Modified Ashworth Scale).were selected and randomly divided into three groups.Group 1 was trained in static upright standing,plus 10 min of sit-to-stand training and 20 min of walking training with no support for the hemiplegic,subluxed shoulder.Group 2 did the same training using a bagtype shoulder sling,and group 3 used the neotype hand-arm sling.Index finger palpation was used to evaluate the degree of shoulder subluxation,and the Five Times Sit-to-Stand (FTSST) and Timed Up-and-Go (TUG) times for the three groups were compared.Results In the static standing training,both the bag-type sling and the neotype hand-arm sling could effectively reduce shoulder subluxation.However,after 10 min of sit-to-stand training the neotype hand-arm sling was found to be significantly superior to the bag-type shoulder sling in improving shoulder subluxation,with the latter having no effect on shoulder subluxation.In the 20 rin of walking training,the neotype hand-arm sling provided significantly more effective support than the bag-type shoulder sling,although both could support the shoulders.Those using the neotype sling had shorter FTSST times,though there were no significant differences in the average TUG times.Conclusions The neotype slings can more effectively counter shoulder subluxation in upright stance,especially during sit-to-stand maneuvers and walking.It might have positive effects on transferring ability.

Objective To study liver regeneration of the non-ligated liver lobes following portal branch ligation (PBL). Methods Sixty male Wistar rats were randomly divided into PBL group and sham operation (SO) group. Under ether anesthesia, the rats were subjected to PBL and sham operation, respectively. The animals were sacrificed on the 1st, 2nd, 3rd, 7th and 14th day respectively. The blood sample was collected from heart and the livers were harvested to determine serum alanine aminotransferase (ALT) levels and total liver weight, respectively. The hepatic histopathology was studied through light microscopy. The number of liver cell nuclear mitosis index was counted. The number of proliferative cell nuclear antigen (PCNA) index was counted by immunohistochemistry. The hepatic ultrastructural changes were studied under electron microscope. Results Elevated serum ALT level was observed in the first postoperative day in PBL group compared with SO group (P

Objective To observe the effects of ICB orthopedic sole combined with rehabilitation training on balance and walking function in stroke survivors.Methods Thirty hemiplegic stroke patients were recruited and divided into a study group (n =15) and a control group (n =15) by using a random number table.Both groups took exercises based on the principles of a motor relearning program and conducted core stability control training,and the study group additionally undertook hemiplegic lower extremity weight-bearing exercises and walking with ICB orthopedic sole used in daily living.The program was administered 20 min twice per day for 4 weeks.All patients were evaluated with Rest Calcaneus Standing Position (RCSP),Malleolar Position (MP),Forefoot Position (FP),Berg Balance Scale (BBS),l0 m Maximum Walking Speed (MWS) and walking section of Motor Assessment Scale (MAS)before and after the program.Results After 4 weeks of intervention,all the measurements except the FP in both groups improved significantly,and significant differences were observed between the two groups.After 4 weeks of training,the average RCSP (1.78 ± 0.32) ° and MP (13.33 ± 2.51)° were improved significantly compared to those of the control group [(2.58 ± 0.59) ° and (12.45 ± 3.31) °,respectively].Moreover,the average BBS,MAS and MWS improved significantly compared to the control group.Conclusions ICB orthopedic sole combined with rehabilitation training can improve the weight-bearing,balance and ambulation abilities of stroke survivors.

In this paper, a novel registration method is presented for three-dimensional mapping of cardiac chambers and computed tomography (CT) segmented surfaces. The proposed method applies random perturbations to three-dimensional mapping of cardiac chambers in order to move out of local minima. It effectively solves the problem of the existing algorithm based on iterative closest point (ICP) in which the optimization often falls into local minima, and improves the registration accuracy and success rate. The registration experiment results show that the final registration accuracy and success rate of the proposed method are better than the existing ICP-based algorithm, and it can implement the registration when the three-dimensional mapping of cardiac chambers and CT segmented surface have a wide range of initial offset.

Objective To observe the nutritional biochemical indicators of paraquat poisoning patients, analyze and compare the nutritional status of patients and understand the changing trend of each indicator. Methods A total of 104 patients with acute paraquat poisoning who were admitted to the emergency department of the Second Hospital of Hebei Medical University from December 2015 to December 2017 were enrolled, and divided into the cure group (patients who survived >30 days) and the death group. Nutritional biochemical indicators including serum protein (ALB, PA, TP) and serum lipids (TCh, TG, LDL) were selected for dynamic observation. The observation time points were set as follows: immediate treatment of poisoned patients (day 1 on admission), on day 4, 7, 10, 13 and 16 after admission, and on day 30 after follow-up. The nutritional biochemical indicators of the two groups on day 1 and 4 were statistically analyzed and compared by t test. The nutritional status of the patients in the cure group was analyzed, and the Repeated Measures Anova was performed to understand the trend of each indicator over time. Results In the cure group, the TP level decreased from (73.34±5.75)g/L on day 1 to (51.95±6.05)g/L on day 4, t=20.34, P<0.01; and the TCh level decreased from (4.37±0.98) mmol/L on day 1 to (3.03±1.01)mmol/L on day 4, t=7.56, P<0.01. In the death group, the TP level decreased from (72.25±8.80)g/L on day 1 to (49.07±5.48)g/L on day 4, t=12.38, P<0.01, and the TCh level decreased from (4.38±0.88)mmol/L on day 1 to (2.51±1.07) mmol/L on day 4, t=7.94, P<0.01. Compared with the cure group, serum levels of ALB, TP and TCh in the death group decreased greater from day 1 to day 4 (all P<0.05). In addition, dynamic observation of the indicators in the cure group within 16 days after admission showed that, after treatment, the levels of ALB and TP recovered slowly and were still lower than normal . While the levels of PA and lipid rose rapidly after 10 days of admission. Conclusions Paraquat poisoning seriously affects the nutritional status of patients, and the serum protein levels decline significantly and can not be recovered easily. Therefore, sufficient attention should be paid to the treatment, and timely and appropriate nutritional support should be provided.

Objective To observe the effect of a walking correcting tape on the kinematics and temporal-spatial indicators of gait after a stroke. Methods Thirty hemiplegic stroke survivors were randomly divided into a control group ( n=15) and a correcting tape group ( n=15) . In addition to their routine rehabilitation program, the control group received 30 minutes of walking training five times a week for 3 weeks with any necessary oral guidance and posture correction. The correcting tape group performed the same walking training assisted by a self-made walking correcting tape. Before and after the treatment, the kinematics and temporal-spatial indicators of both groups were quantified using three-dimensional gait analysis. Results After the treatment, the peak angles of hip and knee flex-ion were significantly higher in the taped group than in the control group and in the taped group before the treatment ( P≤0.05) . After the treatment, the walking speeds, stride frequencies and stride lengths of both groups were signifi-cantly better than before the treatment, but those of the former group were all significantly better than the latter ( P≤0.05 for both) . Conclusions Correcting tape can improve the peak angles of hip and knee flexion of hemiplegic legs and improve the walking capacity of stroke patients.

OBJECTIVE: This study aimed to investigate the expression and clinical significance of proline-rich tyrosine kinase 2 (Pyk2) and phospho-protein kinase B (p-AKT) in tongue squamous cell carcinoma (TSCC) and adjacent nontumor tissues. METHODS: The Pyk2 and p-AKT protein levels were detected via immunohistochemistry in 45 cases of TSCC tissues and 30 cases of adjacent nontumor tissues. The relationships of the two protein levels and clinicopathological characteristics were also analyzed. RESULTS: Pyk2 and p-AKT levels were significantly higher in the TSCC tissues than in the adjacent nontumor tissues (P<0.05). Nontumor tissues showed poor or no expression. The expression levels of the two proteins were positively correlated (γs=0.412). The expression of Pyk2 was associated with histopathological differentiation type, regional lymph node metastasis, and TNM staging (P<0.05), but not with age and gender. The expression of p-AKT was only related to histopathological differentiation types (P<0.05). CONCLUSIONS The abnormal expression of Pyk2 and p-AKT proteins might be closely related to the development and progression of TSCC. Joint detection can be used as an indicator to estimate the degree of TSCC.
