In order to realize an individualized and specialized rehabilitation assessment of remoteness and intelligence, we set up a remote intelligent assessment system of upper limb movement function of post-stroke patients during rehabilitation. By using the remote rehabilitation training sensors and client data sampling software, we collected and uploaded the gesture data from a patient's forearm and upper arm during rehabilitation training to database of the server. Then a remote intelligent assessment system, which had been developed based on the extreme learning machine (ELM) algorithm and Brunnstrom stage assessment standard, was used to evaluate the gesture data. To evaluate the reliability of the proposed method, a group of 23 stroke patients, whose upper limb movement functions were in different recovery stages, and 4 healthy people, whose upper limb movement functions were normal, were recruited to finish the same training task. The results showed that, compared to that of the experienced rehabilitation expert who used the Brunnstrom stage standard table, the accuracy of the proposed remote Brunnstrom intelligent assessment system can reach a higher level, as 92.1%. The practical effects of surgery have proved that the proposed system could realize the intelligent assessment of upper limb movement function of post-stroke patients remotely, and it could also make the rehabilitation of the post-stroke patients at home or in a community care center possible.

OBJECTIVETo evaluate the efficacy and safety of Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion for pancreatic cancer with liver metastases (PCLM).

METHODSWe retrospectively selected 292 patients with PCLM who were treated by Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion at Tianjin Medical University Cancer Hospital from January 2001 to December 2010. All patients were assigned to the Western medicine treatment group (157 cases) and the integrative medicine treatment group (135 cases). Patients in the Western medicine treatment group were treated with gemcitabine (GEM)-based chemotherapy, and partial of them received regional arterial perfusion. Those in the integrative medicine treatment group additionally took Chinese herbs of clearing heat and eliminating mass for at least 4 weeks. The median survival time (MST) , adverse reactions and the incidence of complications were observed.

RESULTSThere was no statistical significance in general data between the two groups (P > 0.05). There was statistical difference in MST between the two groups (4.8 months vs 5.5 months, P < 0.05). No death occurred during chemotherapy or regional arterial perfusion. All toxic or adverse reactions were tolerable.

CONCLUSIONChinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion was effective and safe, and it could be optimally selected as palliative therapy for PCLM.

Objective To investigate the perioperative characteristics and changing trends of gastric electrical activity of thoracic (tube) stomach in patients with esophageal cancer.Methods The clinical data of 30 patients with esophageal cancer who were admitted to the Sichuan Cancer Hospital between March 2013 and November 2013 were prospectively analyzed.All the eligible patients underwent esophageal cancer resection by Ivor-Lewis according to the inclusion criteria.The electrogastrograms of patients were recorded at preoperative day 1 and at postoperative day 3,7, 11 and 30.The electrogastrograms of patients at preoperative day 1 were used as the control.The parameters of electrogastrogram were analyzed including main frequency, coefficient of dominant frequency instablility, main power, postprandial/preprandial power ratio, percentage of normal gastric slow wave,percentage of slow gastric slow wave and percentage of tachycardia gastric slow wave.Measurement data with normal distritution were presented as x ± s, and measurement data with skew distritution were presented as M (Qn).The postoperative time and pre-and post-prandial electrogastrograms were compared by the repeated measures two-way ANOVA.The comparison between groups were evaluated with the LSD test and analysis of variance.Results Thirty patients were screened for eligibility with a mean age of 62 years (range, 49-75 years), including 26 males and 4 females.The pre-and post-prandial main frequencies were changed from 2.83 ± 0.13 and 3.01 ± 0.17 before operation to 2.66 ± 0.10 and 2.82 ± 0.10 at postoperative day 30 with coherent changing trend.The main frequencies at postoperative each time points were significantly lower than those before operation while postprandial above indicators were higher than preprandial those, showing a significant increasing trend with the passage of postoperative time (F =285.62, P ＜ 0.05).There was no interaction between the time and meal (F =0.22, P ＞ 0.05).The pre-and post-prandial coefficients of dominant frequency instablility were changed from 0.133 ±0.031 and 0.045 ±0.019 before operation to 0.150 ±0.043 and 0.115 ±0.010 at postoperative day 30 with coherent changing trend, and coefficients of dominant frequency instablility at postoperative each time points were significantly higher than those before operation while postprandial above indicators were lower than preprandial those, showing a significant reducing trend with the passage of postoperative time (F =16.51, P ＜ 0.05).The pre-and post-prandial main powers were changed from (85 ± 15) μV and (149 ± 23) μV before operation to (74 ± 9) μμV and (98 ± 10) μV at postoperative day 30, and main powers at postoperative each time points were significantly lower than those before operation, showing a significant increasing trend with the passage of postoperative time (F =48.45, P ＜ 0.05).There was interaction between the time and meal (F =7.39, P ＜ 0.05).The postprandial/preprandial power ratio was changed from 3.00 ± 0.35 before operation to 2.52 ± 0.25 at postoperative day 30, and postprandial/preprandial power ratios at postoperative each time points were significantly lower than those before operation, showing a significant increasing trend with the passage of postoperative time (F =26.66, P ＜ 0.05).The pre-and post-prandial percentages of normal gastric slow wave were changed from 81％ ± 6％ and 94％ ± 5％ before operation to 57％ ± 5％ and 70％ ± 5％ at postoperative day 30 with coherent changing trend, and percentages of normal gastric slow wave at postoperative each time points were significantly lower than those before operation while postprandial above indicators was lower than preprandial those, showing a significant increasing trend with the passage of postoperative time (F =49.36,P ＜0.05).There was no interaction between the time and meal (F =0.24, P ＞ 0.05).The pre-and postprandial percentages of slow gastric slow wave were changed from 17％ ± 7％ and 4％ ± 4％ before operation to 32％±4％ and 21％±4％ at postoperative day 30 with coherent changing trend, and percentages of slow gastric slow wave at postoperative each time points were significantly higher than those before operation while preprandial above indicators were higher than postprandial those, showing a significant reducing trend with the passage of postoperative time (F =46.54, P ＜ 0.05).There was interaction between the time and meal (F =18.12, P ＜ 0.05).The pre-and post-prandial tachycardia gastric slow wave percentages were changed from 1.55％ (1.04％,2.21％) and 1.95％ (1.74％, 4.22％) before operation to 8.97％ (5.76％, 12.02％) and 12.41％ (8.04％,16.85％) at postoperative day 30 without completely coherent changing trend, and percentages of tachycardia gastric slow wave at postoperative each time points were significantly higher than those before operation while postprandial above indicators were higher than preprandial those, showing a significant difference between before operation and postoperative day 3 (Z =11.47, 13.28, P ＜ 0.05) and no significant difference among the postoperative day 7, 11, 30 (Z =1.88, 0.31, 0.03, P ＞ 0.05).There was no interaction between the time and meal (F=0.85, P＜0.05).Conclusions After the esophagectomy, gastric electrical activity of thoracic (tube) stomach is also retained before and after the meal.There are significant differences among the main frequency, main power, coefficients of dominant frequency instablility, postprandial/preprandial power ratio,percentage of normal gastric slow wave, percentage of slow gastric slow wave, percentage of tachycardia gastric slow wave of thoracis (tube) stomach, they have changed dynamically in the perioperative period.
