Objective To investigate the effect of continuous passive motion(CPM) and rehabilitation on flexion of the shoulder after intensive burn.Methods 36 patients with intensive burn on upper limb(including the skin around axilla fossa) were divided randomly into CPM group(n=19) and control group(n=17).The CPM group received both routine rehabilitation and continuous passive motion treatment,and the control group only underwent routine rehabilitation treatment.Their ranges of active or passive motion were assessed.Results There was a significant improvement both in the CPM group and the control group after treatment(P<0.01),but the CPM group improved more(P<0.05).Conclusion CPM can improve the efficacy of the routine rehabilitation on flexion of the shoulder after intensive burn.

Objective To observe the effect of reciprocating gait orthosis on walking ability and activities of daily living (ADL) of patients with C6～T6 spinal cord injury (SCI).Methods 20 cases with C6～T6 SCI and according with type A and type B of ASIA standard received rehabilitation therapy, including training of muscle power, cardiopulmonary function, transferring mobility, ADL, bladder function, etc., before assembling the reciprocating gait orthosis, and additional gait training after fixing orthosis. The timed walking function assessment (6-min walking test and timed 10 meters walking test), gait analysis, Modified Barthel Index (MBI) and Functional Independence Measure (FMI) were used to assess pre- and post-training.Results The ADL ability of all cases improved obviously after equipping reciprocating ambulation orthosis, the walking ability also improved (P＜0.05). The mean timed 10 meters was 99.21±75.24 s, mean 6-min walk test was 41.71±29.38 m. From all patients, 14 cases achieved practicability walking ability, 6 cases achieved domestic walking ability.Conclusion The reciprocating gait orthosis combined with comprehensive rehabilitation therapy has effect on walking ability and ADL of patients with C6～T6 SCI.

Objective To observe the effect of ankle-foot orthosis(AFO)on the activities of daily living(ADL)and walking ability of patients with low lumbar spinal cord injury.Methods29 cases with low lumbar spinal cord injury were trained by systematic rehabilitation.According to patients' condition,static AFO or dynamic AFO were assembled for them.All patients were evaluated with Modified Barthel Index(MBI)and Functional Independence Measure(FIM)before and after training,and the walking distances were also measured.ResultsAfter AFO dressed,the ADL scores of patients increased,especially walking ability increased significantly(P<0.05).Of 29 patients,26 cases had outdoor walking ability,3 cases had domestic walking ability.ConclusionSelecting different kinds of AFO according to condition of individual can help patients with low lumbar spinal cord injury to reconstruct their walking ability and improve ability of self-management.

The incidence and mortality rates of gastrointestinal (GI) cancer remain high. Despite constant improvements in diagnostic and therapeutic techniques, the early diagnosis, mid- and late-stage treatment, drug tolerance, and cancer recurrence and metastasis in GI cancer remain challenging. In this review article we summarize the recent research advance in the roles of keratins in GI cancer, with the hope that they will become efficient biomarkers for the prediction, diagnosis, or treatment of these malignancies.

Objective:To investigate the risk factors for early complications after laparoscopy-assisted gastrectomy in patients with gastric cancer.Methods:The retrospective case-control study was conducted. The clinicopathological data of 196 patients who underwent laparos-copy-assisted radical gastrectomy at Peking Union Medical College Hospital from March 2016 to March 2019 were collected. There were 144 males and 52 females, aged (61±10)years. Observation indicators: (1) early complications after laparoscopy-assisted radical gastrectomy and treatment; (2) analysis of risk factors for early complications after laparoscopy-assisted radical gastrectomy.Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M( P25,P75). Count data were represented as absolute numbers. Univariate analysis was conducted using the t test, Mann-Whitney U test or chi-square test. Multivariate analysis was conducted using the Logistic regressional model. Results:(1) Early complications after laparoscopy-assisted radical gastrectomy and treatment: 51 of 196 patients had early postoperative complications, including 7 cases of grade Ⅰ according to Clavien-Dindo classi-fication system, 32 cases of grade Ⅱ, 9 cases of grade Ⅲa, 3 cases of grade Ⅲb. There was no grade Ⅳ or Ⅴ complication. There were 25 cases with abdominal complications, 7 cases with thoracic complications, 3 cases with internal/catheter related complications and 16 cases with other unclassified complications. All patients with complications were improved after symptomatic and supportive treatments. (2) Analysis of risk factors for early complications after laparoscopy-assisted radical gastrectomy: results of univariate analysis showed that the lymphocyte count, neutrophil-to-lymphocyte ratio, radiotherapy, operation time, volume of intraoperative blood loss, T stage, lymph node metastasis were related factors for early complications after laparoscopy-assisted radical gastrectomy in patients with gastric cancer ( Z=?2.048, χ2=6.385, 4.168, 8.068, 6.336, 12.497, 7.522, P<0.05). Results of multivariate analysis showed that the neutrophil/lymphocyte ratio ≥1.96, operation time ≥222 minutes, and lymph node metastasis were independent risk factors for early complica-tions after laparoscopy-assisted radical gastrectomy in patients with gastric cancer ( odds ratio=2.279, 2.245, 2.226, 95% confidence interval as 1.149-4.519, 1.116-4.517, 1.125-4.402, P<0.05). Conclusions:The abdominal complications are the most common early complications after laparoscopy-assisted radical gastrectomy. The neutrophil-to-lymphocyte ratio ≥1.96, operation time ≥222 minutes, and lymph node metastasis are independent risk factors for early complications after laparoscopy-assisted radical gastrectomy in patients with gastric cancer.
