ABSTRACT
Spinal cord injury (SCI) causes motor, sensory, and autonomic dysfunctions. The gut microbiome has an important role in SCI, while short-chain fatty acids (SCFAs) are one of the main bioactive mediators of microbiota. In the present study, we explored the effects of oral administration of exogenous SCFAs on the recovery of locomotor function and tissue repair in SCI. Allen's method was utilized to establish an SCI model in Sprague-Dawley (SD) rats. The animals received water containing a mixture of 150 mmol/L SCFAs after SCI. After 21 d of treatment, the Basso, Beattie, and Bresnahan (BBB) score increased, the regularity index improved, and the base of support (BOS) value declined. Spinal cord tissue inflammatory infiltration was alleviated, the spinal cord necrosis cavity was reduced, and the numbers of motor neurons and Nissl bodies were elevated. Enzyme-linked immunosorbent assay (ELISA), real-time quantitative polymerase chain reaction (qPCR), and immunohistochemistry assay revealed that the expression of interleukin (IL)-10 increased and that of IL-17 decreased in the spinal cord. SCFAs promoted gut homeostasis, induced intestinal T cells to shift toward an anti-inflammatory phenotype, and promoted regulatory T (Treg) cells to secrete IL-10, affecting Treg cells and IL-17+ γδ T cells in the spinal cord. Furthermore, we observed that Treg cells migrated from the gut to the spinal cord region after SCI. The above findings confirm that SCFAs can regulate Treg cells in the gut and affect the balance of Treg and IL-17+ γδ T cells in the spinal cord, which inhibits the inflammatory response and promotes the motor function in SCI rats. Our findings suggest that there is a relationship among gut, spinal cord, and immune cells, and the "gut-spinal cord-immune" axis may be one of the mechanisms regulating neural repair after SCI.

Objective:To explore the effect of sciatic nerve derived exosomes(SN-EXO) on axon regeneration and functional recovery after peripheral nerve injury(PNI).Methods:From March 2021 to October 2022, the Department of Orthopedics of the First Affiliated Hospital of Zhengzhou University studied the effect of SN-EXO on the proliferation of Schwann cells(SCs) through EdU cell proliferation experiment. Twenty-one healthy male SD rats were randomly divided into 3 groups of sham operation, peripheral nerve injury(PNI) and SN-EXO treatment, with 7 rats in each group. The right sciatic nerves of rat models in sham group were exposed without injury. In the rat in PNI group and SN-EXO treatment group, PBS and SN-EXO were injected under the epineurium of right sciatic nerves following sciatic nerve crush. Sciatic nerve function index(SFI) was performed at 28 days after operation, and then sacrificed. Right sciatic nerves were removed for further exploration of nerve regeneration. The histopathological changes and axon arrangement of sciatic nerves were evaluated by HE staining. Regeneration efficiency of neurofilaments and SCs were obserred by NF200 and S100β double staining of sciatic nerve. The data obtained were statistically analyzed, and P<0.05 was statistically significant. Results:It was found that SN-EXO can significantly enhance the proliferation ability of SCs, with statistically significant difference( P<0.05). SFI in SN-EXO treatment group and PNI group were(-27.65±4.36) and(-57.33±7.49), respectively, and the difference was statistically significant( P<0.05). Axons in SN-EXO treatment group were arranged more closely and orderly than those in the PNI group at 28 days after operation, and there were less injury induced axon disintegration and vacuolation. Immunofluorescence assay indicated that NF200 and S100β fluorescence intensity in SN-EXO treatment group was significantly higher than that in the PNI group, and the difference was statistically significant( P<0.05). Conclusion:SN-EXO could enhance the proliferation of SCs to promote axon regeneration following peripheral nerve injury.
ABSTRACT
Objective To explore the effect of proprioceptive neuromuscular facilitation (PNF) rehabilitation training on functional recovery of athletic rotator cuff injury. Methods Twenty-two college students with athletic rotator cuff injuries were stratified according to their gender and randomly divided into resistance band + passive joint range of motion (ROM) training group (control group) and PNF training group (experimental group). The visual analog scale (VAS) was used to evaluate subjective pain intensity of the shoulder joint. Pain positive rate for each manipulation test of rotator cuff injury was observed, and active ROM and muscle strength of the shoulder joint were measured. Improved UCLA shoulder joint score was used to evaluate comprehensive function of the shoulder joint. Results After training, VAS scores and pain positive rate in two groups were lower than those before training, and VAS scores and pain positive rate in experimental group were lower than those in control group. Muscle strength, active ROM in all directions and improved UCLA score of the shoulder joint in two groups were also higher than those before training, and the internal rotation muscle strength, the internal rotation and external rotation active ROM, improved UCLA score of the shoulder joint in experimental group were higher than those in control group. Conclusions PNF rehabilitation training can reduce the pain of athletic rotator cuff injury, improve the active ROM, muscle strength and UCLA shoulder joint score. The function recovery effect of PNF training is better than that of resistance band + passive ROM training.

Objective: To investigate the efficacy of total hip arthroplasty (THA) assisted by the MAKO robotic arm via posterolateral approach. Methods: The clinical data of 70 patients treated with THA via posterolateral approach between March 2017 and March 2019 who met the selection criteria were retrospectively analyzed. According to different treatment methods, the patients were divided into two groups, 35 were treated with MAKO robotic arm assisted THA (MAKO group) and 35 with traditional THA (THA group). There was no significant difference in gender, age, body mass index, disease duration, etiology, perioperative time, preoperative activity of daily living (ADL) scale index, American Society of Anesthesiologists (ASA) classification, walking ability, comorbidities, hemoglobin, and other general data between the two groups ( P>0.05). The operation time, intraoperative blood loss, hospital stay, postoperative acetabular abduction and anteversion angles, postoperative length difference of bilateral lower limbs, and proportions of intraoperative blood transfusion, immediate postoperative loading, wound drainage time more than 2 days, and complications were recorded and compared between the two groups. According to the X-ray films at 6 months after operation, the reduction quality was judged. The forgotten joint score, Harris score, and proportions of independent walking and ADL index increased were used to evaluate the function recovery of patients. Results: Patients in both groups were followed up 6-18 months, with an average of 8 months. There was no significant difference ( P>0.05) between the two groups in operation time, intraoperative blood loss, hospital stay, acetabular abduction and anteversion angles, and length difference of both lower limbs at 6 months after operation. There was no significant difference in the proportions of intraoperative blood transfusion, immediate postoperative loading, and wound drainage time more than 2 days between the two group ( P>0.05). X-ray reexamination at 6 months after operation showed that there was no significant difference in the reduction quality between the two groups ( Z=4.191, P=0.123). Postoperative complications occurred in 7 patients (20.0%) in the MAKO group and 10 patients (28.6%) in the THA group, showing no significant difference in the incidence of complications between the two groups ( χ2=2.121, P=0.224). Two patients (5.7%) in the MAKO group and 4 patients (11.4%) in the THA group underwent revision within 6 months, showing no significant difference in the revision rate between the two groups ( χ2=0.729, P=0.673). At 3 and 6 months after operation, the proportions of independent walking and ADL index increased showed no significant difference between the two groups ( P>0.05). Harris scores in both groups improved significantly when compared with preoperative scores ( P0.05). Conclusion: Compared with traditional THA, MAKO robotic arm assisted THA has longer operation time and more intraoperative blood loss, but it has the advantages of accurate positioning and simple operation, and there is no significant difference in short-term postoperative function recovery.
ABSTRACT
Neurological damage caused by stroke is one of the main causes of motor dysfunction in patients, which brings great spiritual and economic burdens for society and families. Motor imagery is an important assisting method for the rehabilitation of patients after stroke, which is easy to learn with low cost and has great significance in improving the motor function and the quality of patient's life. This paper mainly summarizes the positive effects of motor imagery on post-stroke rehabilitation, outlines the physiological performance and theoretical model of motor imagery, the influencing factors of motor imagery, the scoring criteria of motor imagery and analyzes the shortcomings such as the few kinds of experimental subject, the subjective evaluation method and the low resolution of the experimental equipment in the process of rehabilitation of motor function in post-stroke patients. It is hopeful that patients with stroke will be more scientifically and effectively using motor imagery therapy.
ABSTRACT
Objective To study the clinical efficacy of platelet-rich plasma (PRP) in the treatment of acute Achilles tendon rupture.Methods A retrospective study was performed of the 21 patients who had been treated for acute Achilles tendon rupture at Department of Orthopaedics,The First Affiliated Hospital to Soochow University from January 2018 to January 2019.Of them,15 were treated by modified Kessler suture combined with PRP injection (PRP group) and 6 by simple modified Kessler suture (control group).The 2 groups were compared in terms of plantar flexion,dorsal expansion,visual analogue scale (VAS),Victorian Institute of Sport Assessment (VISA),and ankle-hindfoot score of American Orthopaedic Foot and Ankle Society (AOFAS) at 3,6,and 9 months postoperation.Results The 2 groups were comparable due to insignificant differences between them in the preoperative general data (P ＞ 0.05).All patients were followed up for 9 to 12 months (mean,11.3 months).At 3,6,and 9 months postoperation,the degrees of plantar flexion (33.5°±1.8°,38.1°±1.2°and41.6°±1.6°) and dorsal expansion (10.3°,16.5°and 21.5°) in the PRP group were all significantly larger than those in the control group (26.9°± 2.0°,31.5°±1.6°and35.6°±1.4°;5.3°,12.7°±0.6°and 18.2°),and the VISA scores (41.2±6.5,78.7±10.4 and 91.0 ± 4.1) and the AOFAS scores (75.5 ± 5.4,88.6 ± 5.2 and 95.2 ± 3.5) in the PRP group were all significantly higher than those in the control group (29.8 ±2.5,68.0 ±3.5 and 84.5 ±2.1;66.8 ±4.8,82.8 ±3.6 and 90.7 ± 1.1) (all P ＜ 0.05).At 3 and 6 months postoperation,the VAS scores in the PRP group (1.7 ± 0.9 and 1.3 ±0.4) were significantly lower than those in the control group (3.0±0.8 and 2.2 ± 0.7) (all P ＜ 0.05).Conclusion As PRP can release a high concentration of growth factors to promote recovery of Achilles tendon rupture and accelerate recovery of foot and ankle function,it can be considered a safe,practical and reliable treatment to use modified Kessler suture plus PRP injection.
ABSTRACT
Objective To explore the safety application of organs from infectious donors. Methods Clinical data of 67 donors and recipients undergoing orthotopic liver transplantation were retrospectively analyzed. According to the occurrence of infections and infection sites in donors, all recipients were divided into the bloodstream infection group (n=16, donors with non-drug resistant bacterial infections), non-bloodstream infection group (n=20, donors with other site infections) and non-infection group (n=31). Perioperative clinical parameters including preoperative model for end-stage liver disease (MELD) score, operative time, anhepatic phase, intraoperative blood loss and intraoperative blood transfusion were statistically compared among three groups. The recovery of liver function and coagulation function in the recipients was observed at postoperative 1, 3, 7, 14 and 21 d. The incidence rate of complications and mortality rate in the recipients were recorded within 1 month after liver transplantation. The recovery of postoperative infection-related parameters including white blood cell (WBC), neutrophil pet (NE%) and procalcitonin (PCT) level in the recipients was observed. The application rate and application time of restricted antibiotics were recorded. Results Perioperative clinical parameters in the recipients did not significantly differ among three groups (all P > 0.05). At each time point after liver transplantation, the liver function, coagulation function, incidence rate of complications and mortality rate in the recipients did not significantly differ among three groups (all P > 0.05). The NE% of recipients at postoperative 3 and 7 d in the bloodstream infection group was significantly higher than those in non-bloodstream infection and non-infection groups (all P < 0.05). The PCT levels of recipients at postoperative 3, 7 and 14 d in the bloodstream infection group were significantly higher than those in the non-bloodstream infection and non-infection groups (all P < 0.05). The application rate and application time of restricted antibiotics in the recipients with bloodstream infections were significantly higher or longer than their counterparts in the non-bloodstream infection and non-infection groups (all P < 0.05). Conclusions It is safe to apply liver grafts from donors with bloodstream infection of non-drug resistant bacteria or other site infections when antibiotics are applied as early as possible.
ABSTRACT
Objective • To investigate the effect of hyperthermic intraperitoneal chemotherapy on postoperative gastrointestinal function recovery in patients with gastrointestinal cancer. Methods • Sixty-two cases of gastrointestinal cancer patients were enrolled who accepted cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in Department of General Surgery, Shanghai Public Health Clinical Center, Fudan University, from July 2014 to June 2017. The gastrointestinal function of patients were evaluated according to the I-FEED scoring system. The patients were divided into normal recovery group (I-FEED score<6, n=38) and delayed recovery group (I-FEED score ≥ 6, n=24). Univariate and multivariate Logistic analyses were performed on characteristic factors that may affect the recovery of postoperative gastrointestinal function including gender, age, presence of diabetes, preoperative albumin, and so on. Results • There were significantly differences in the preoperative serum albumin level (P=0.040), intraoperative bleeding (P=0.044), the time of extraction of the peritoneal cavity drainage tube (P=0.026), the time of urethral tube extraction (P=0.021) and the time of hospitalization (P=0.017) in the two groups of patients with normal or delayed gastrointestinal function recovery. Multivariate Logistic regression results suggested that preoperative serum albumin level may be beneficial for the recovery of postoperative gastrointestinal function (OR=0.84, 95% CI 0.17-4.27, P=0.041). Conclusion • The preoperative serum albumin level can be used as an independent predictor of postoperative gastrointestinal functional recovery in patients with gastrointestinal cancer after cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy.

ABSTRACT
OBJECTIVE: To evaluate the effects of electric cortical stimulation (ECS) and transcranial direct current stimulation (tDCS) on motor and cognitive function recovery and brain plasticity in focal traumatic brain injury (TBI) of rats model. METHODS: Forty rats were pre-trained to perform a single pellet reaching task (SPRT), rotarod test (RRT), and Y-maze test for 14 days, then a focal TBI was induced by a weight drop model on the motor cortex. All rats were randomly assigned to one of the three groups: anodal ECS (50 Hz and 194 μs) (ECS group), tDCS (0.1 mA, 50 Hz and 200 μs) (tDCS group), and no stimulation as a control group. Four-week stimulation, including rehabilitation, was started 3 days after the operation. SPRT, RRT, and Y-maze were measured from day 1 to day 28 after the TBI was induced. Histopathological and immunohistochemistry staining evaluations were performed at 4 weeks. RESULTS: SPRT was improved from day 7 to day 26 in ECS, and from day 8 to day 26 in tDCS compared to the control group (p < 0.05). SPRT of ECS group was significantly improved on days 3, 8, 9, and 17 compared to the tDCS group. Y-maze was improved from day 8 to day 16 in ECS, and on days 6, 12, and 16 in the tDCS group compared to the control group (p < 0.05). Y-maze of the ECS group was significantly improved on day 9 to day 15 compared to the tDCS group. The c-Fos protein expression was better in the ECS group and the tDCS group compared to the control group. CONCLUSION: Electric stimulation in rats modified with a focal TBI is effective for motor recovery and brain plasticity. ECS induced faster behavioral and cognitive improvements compared to tDCS during the recovery period of rats with a focal TBI.

ABSTRACT
La parálisis cerebral infantil es una enfermedad neurológica no progresiva. Es una de las causas más comunes de discapacidad en niños. Son numerosas las técnicas de terapia física que se emplean en la actualidad para su tratamiento; el vendaje neuromuscular es una de ellas. El objetivo principal es revisar los resultados logrados por el vendaje neuromuscular en los estudios científicos publicados en pacientes pediátricos con parálisis cerebral y determinar la calidad metodológica de ellos. Se revisaron las principales bases de datos científicas, al igual que los estudios publicados en la página oficial de la Asociación Española de Vendaje Neuromuscular. Se admitieron nueve estudios, que han aportado resultados importantes. Estos estudios muestran la efectividad para recuperar funcionalidad en el miembro superior, problemas de deglución y funcionalidad motora que estos pacientes pudieran presentar, aunque la evidencia científica que mostraron puede incrementarse con mejoras en su metodología.

Objective To observe the influence of early involvement of rehabilitation treadmill on hip function and daily life after total hip arthroplasty (THA).Methods Totally 80 patients receiving THA in Foshan Hospital of Traditional Chinese Medicine from January 2013 to January 2016 were randomized into a trial group (40 cases) and a control group (40 cases).The control group underwent conventional rehabilitation treatment such as training of muscle strength,joint motion and daily life,and the trial group applied rehabilitation treadmill for early training besides above measures.The two groups were compared on Harris score,Barthel scaore and re-visiting rate at the time points of 1,3 and 6 months after THA.Results Follow-up was carried out for the two groups.Harris scores and Barthel scores of the two groups were significantly enhanced 3 and 6 months after THA (P＜0.05).Harris scores in the trial group were (83.08±2.38) and (88.05±2.54) respectively 3 and 6 months after THA,which were statistically higher than (69.03±2.39) and (74.85±3.39) of the control group.Barthel scores in the trial group were (79.25±3.31) and (90.25+2.25) respectively 3 and 6 months after THA,which were obviously higher than (75.13±3.10) and (84.88±3.84) in the control group.The trial group had the re-visiting rate (17.5％) significantly higher than that (37.5％) in the control group 6 months after THA (P＜0.05).Conclusion Early involvement of rehabilitation treadmill combined with conventional training promotes the recovery of hip function,lower limb muscle strength,walking ability and daily life,while decreases the re-visiting rate of the patient.
ABSTRACT
@#BACKGROUND:This systematic review aims to investigate the prediction value of diffusion tensor imaging for motor function recovery of ischemic stroke patients. METHODS:Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2016, Issue 9), PubMed, Embase, Clarivate Analytics, Scopus, CINAHL, Chinese Biomedical Literature Database, China National Knowledge Infrastructure and Google Scholar were searched for either motor recovery or corticospinal tract integrity by diffusion tensor imaging in different stroke phase from January 1, 1970, to October 31, 2016. The study design and participants were subjected to metrological analysis. Correlation coefficient (r) was used for evaluating the relationship between fractional anisotropy (FA) and motor function outcome. Correlation coefficient values were extracted from each study, and 95％ confidence intervals (CIs) were calculated by Fisher's z transformation. Meta-analysis was conducted by STATA software. RESULTS:Fifteen studies with a total of 414 patients were included. Meta-analysis showed that FA in the subacute phase had the significant correlation with motor function outcome (ES=0.75, 95％CI 0.62-0.87), which showed moderate quality based on GRADE system. The weight correlation coefficient revealed that an effect size (ES) of FA in acute phase and chronic phase was 0.51 (95％CI 0.33-0.68) and 0.62 (95％CI 0.47-0.77) respectively. CONCLUSION:This meta-analysis reveals that FA in the subacute phase after ischemic stroke is a good predictor for functional motor recovery, which shows moderate quality based on the GRADE system.
ABSTRACT
Objective:To evaluate the influence of different CO2 pneumoperitoneum pressure on intestinal mucosal injury and intestinal function recovery in patients undergoing laparoscopic radical gastrectomy.Methods:A total of 120 patients undergoing laparoscopic radical gastrectomy were randomly divided into group A,B and C.Each group included 40 patients.CO2 pneumoperitoneum pressure ingroup A,B and C were 8～10 mmHg,11～13 mmHg and 14～16 mmHg,respectively.The degree of intestinal mucosa damage,plasma D-lactate(2,24 and 48 hours after the treat-ment),intestinal function recovery and complication ration were compared between the three groups.Results:Damage degree of intestinal mucosa after operation in A,B and C groups were 0～1,1～2 and 2～3 respectively.There was significant change in intestinal mucosa injury after operation in both B and C groups.The level of D-lactic acid in group C (2,24 and 48 hours after the treat-ment) were significantly higher those in group A and group B (P＜0.05).The bowel sounds appeared time,exhaust time and intake time in group C were significantly longer than group A and group B (P＜0.05).The incidence of complications were not significantly difference during the three groups.Conclusion:The high pressure of CO2 pneumoperitoneum will cause intestinal mucosa damaged,and not conducive to the patients' intestinal rehabilitation.We suggest that the CO2 pneumoperitoneum pressure should be as low as possible under clear visualization during operation.
ABSTRACT
A reabilitação do membro superior do paciente com sequelas de acidente vascular encefálico é um dos desafios de maior complexidade para o fisioterapeuta. O objetivo deste estudo foi verificar o uso da Terapia de Contenção Induzida (técnica recente) isoladamente na melhora funcional do membro superior parético em pacientes pós-acidente vascular encefálico a partir de uma revisão sistemática sem metanálise das bases de dados PubMed,LILACS e SciELO, seguindo os critérios de inclusão: ano de publicação entre 2010 e 2015, estudos clínicos controlados e randomizados que avaliaram a funcionalidade do membro superior hemiparético, e estudos que utilizaram somente a Terapia de Contensão Induzida como técnica de tratamento no mesmo grupo estudado. Foram critérios de exclusão relativos à Terapia de Contensão Induzida: associada a outras técnicas de reabilitação no mesmo grupo estudado, modificada, realizada para fins que não para o membro superior parético, e realizada em crianças e adolescentes ou em pacientes com paralisia cerebral. Foram encontrados 352 artigos. Seis artigos se enquadraram nos critérios de inclusão e exclusão. Dos seis artigos, três apresentaram a comparação da Terapia de Contensão Induzida com outras técnicas, como Bobath, estimulação magnética transcraniana repetitiva de baixa frequência, terapia ocupacional e terapia intensiva bilateral. Dois artigos verificaram a Terapia de Contensão Induzida precoce e tardiamente; somente um avaliou o fluxo sanguíneo do hemisfério afetado durante tarefas motoras com e sem restrição. Conclui-se que a Terapia de Contensão Induzida utilizada precocemente oferece resultados satisfatórios quando comparados com técnicas mais tradicionais.
Upper limb rehabilitation in patients with stroke sequelae is one of the most complex challenges to the physiotherapist. The aim of this study was to investigate the use of constraint-Induced movement therapy (recent technique) alone in functional improvement of the paretic upper limb in post-stroke patients through a systematic review with no metanalysis of databases of PubMed, LILACS and SciELO. The inclusion criteria were: year of publication between 2010 and 2015; controlled and randomized clinical studies that evaluated the functionality of hemiparetic upper limb, and controlled and randomized clinical studies evaluating only the Constraint-induced Movement Therapy as a treatment technique in the same study group.Exclusion criteria related to the Constraint-induced Movement Therapy were: associated with other rehabilitation techniques in the same study group, modified, carried out for purposes other than for the paretic upper limb, and performed in children and teenagers or in patients with cerebral palsy. We found 352 articles. Six articles met the inclusion and exclusion criteria. Of the six articles, three had a comparison of Constraint-induced movement therapy with other techniques, such as Bobath,low-frequency repetitive transcranial magnetic stimulation,occupational therapy, and bilateral intensive therapy. Two articles observed early and late Constraint-induced Movement Therapy; only one evaluated the blood flow of the affected hemisphere during motor tasks with and without constraint. It was concluded that the Constraint-induced Movement Therapy use provides satisfactory results when compared with more traditional techniques

Objective To observe the effects of early-stage exercise on function recovery and ED1 expres-sion after spinal cord injury. Methods Twenty-two SD rats were randomly divided into a control group ( n=8) , an exercise group ( n=8) and a sham-operated group ( n=6) . The control and exercise groups received T9 spinal cord contusions. The sham-operated group received only T9 laminectomy without spinal cord injury. Two rats died within 6 hours after the operation and 3 others were abandoned because of motor function recovery just after the spi-nal cord contusion. The remaining 17 were included in the statistical analysis: a control group of 6, an exercise group of 5 and a sham-operated group of 6. BBB scoring was conducted 2 days later and then weekly until 8 weeks after the operation. The exercise group began treadmill and wheel running exercise on day 2 and continued 5 times per week until the 8th week. After paraformaldehyde perfusion, fixation and embedding, frozen spinal cord slices were Nissl stained for ED1 and GFAP immunofluorescence measurements. Results Compared with the control group, the average BBB score of the exercise group was significantly higher at each week except weeks 2 and 4. By weeks 7 and 8, the exercised rats showed 13.60 and 14.60 BBB punctuation, which means that those animals took frequent, consistent, weight-supporting plantar steps, consistent with FL-HL coordination. That motor behavior was not achieved by the control group even occasionally. In terms of the tissue morphology and immunohistochemical staining results, the empty area was not significantly reduced in the exercise group compared with the controls, but the damaged area was significantly reduced. In addition, ED1 positive cells in the lesioned area were significantly reduced in the exercised group compared with the controls. Conclusions Exercise can promote the recovery of motor function after spinal cord injury. The mechanism may involve reducing the lesioned area and inflammatory response.
ABSTRACT
Objective:To determine whether chewing gum during the postoperative period facilitates the recovery of bowel function in patients after radical cystectomy with ileum urinary diversion.Methods:In the study,60 patients who underwent radical cystectomy followed by ileum urinary diversions during Nov.2014 and Nov.2015 in Department of Urology of Peking University First Hospital were randomized into three groups:gum chewing group,placebo group treated with the abdomen physical therapy machine and control group treated with ordinary method.Time to flatus,time to bowel movement,incidence of postoperative distension of the abdomen and abdominal pain,and gut related complications (such as ileus,intestinal fistula,and volrulus)of all the patients were recorded and analysed.Results:In gum chewing group,the median time to flatus was 57 hours (49 -72 hours),and the median time to bowel movement was 95 hours (88 -109 hours),which were significantly shortened compared with the other two groups of patients (82 hours,109 hours in placebo group and 81 hours,108 hours in control group, respectively).No significant difference of the median time to flatus and to bowel movement was observed between placebo group and control group.There were no significant differences in the incidence of post-operative distension of the abdomen and abdominal pain,and gut related complications among the three groups.Conclusion:Chewing gum had stimulatory effect on bowel function recovery after cystectomy fol-lowed by ileum urinary diversion.Chewing gum was safe and simple,and could be routinely used for postoperative treatment after cystectomy and ileum urinary diversion.
ABSTRACT
Objective To explore pathological characteristics of different white matter tracts at core of the spinal cord injury (SCI) in adult rats. Methods 21 adult female Wistar rats were divided into normal group (n=3), sham group (n=3) and lesion group (n=15). The rats of the lesion group were severely injured at T7-8 using the NYU impactor of 10 g×50 mm. The pathology of spinal cord injury was detected using Luxol fast blue (LFB) staining and NF200 immunohistochemistry staining 1 day, 3 days, 7 days, 14 days and 28 days after injury, while the hindlimbs behavior of rats was rated with Basso-Beattie-Bresnahan (BBB) scores of open-field. Results The BBB scores recov-ered 3 days after injury and reached a platform from 14 to 28 days after injury. LFB showed that there were spared white matters on ventral white matter (VWM) and lateral white matter (LWM). The percentage of spared white matters area decreased to the lowest 3 days after inju-ry, and reached a platform from 7 to 28 days after injury. The number of NF200-IR axons reduced significantly in white matter tracts after SCI. Conclusion Ventral spared white matters plays a key role in the recovery of motor function in rat with SCI, and the first 3 days was a time window to protect the white matters from injury.
