RESUMO
Objective:To investigate the effects of Flexi-bar on nonspecific low back pain. Methods:From June, 2020 to January, 2021, 30 patients with nonspecific low back pain were enrolled. Firstly, all the patients performed core stabilization exercise (supine bridge, curl-up and four-point support) using Flexi-bar or not, respectively. And the difference of electromyography (EMG) root mean square (RMS) value of transversus abdominis and multifidus was observed. Secondly, they were randomly divided into control group (n = 15) and experimental group (n = 15). The control group performed core stabilization exercise, and the experimental group received Flexi-bar training in addition, 30 minutes a time, three times a week, for six weeks. They were evaluated with Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI), and measured the thickness of transversus abdominis and the area of multifidus before and after training. Results:Firstly, there was significant difference in RMS of transversus abdominis and multifidus between using Flexi-bar or not (|t| > 2.468, P < 0.05), except the RMS of transversus in supine bridge (|t| < 2.029, P > 0.05). Secondly, before training, there was no significant difference between the control group and the experimental group (|t| < 1.944, P > 0.05); after training, the scores of VAS and ODI significantly decreased (|t| > 6.808, P < 0.001), the thickness of transversus abdominis and the area of multifidus significantly increased (|t| > 5.937, P < 0.001), and all the indexes were better in the experimental group than in the control group (|t| > 2.411, P < 0.05)， except the thickness of transverse abdominis (t = -1.431, P > 0.05). Conclusion:Flexi-bar could facilitate to reduce pain and improve the function of patients with nonspecific low back pain.
RESUMO
Objective:To observe the efficacy and safety of repetitive transcranial magnetic stimulation (rTMS) in frequencies of 5 Hz and 10 Hz for post-herpetic neuralgia (PHN). Methods:From March, 2017 to March, 2018, 60 PHN patients were randomly divided into groups A (n = 20), B (n = 20) and C (n = 20), who accepted sham rTMS, 5 Hz rTMS and 10 Hz rTMS, respectively, ten times for two weeks. They were assessed with Visual Analogue Scale (VAS) of pain, Pittsburgh Sleep Quality Index (PSQI), Patients' Global Impression of Change Scale (PGIC), medication regulation (MR) and incidence of adverse events, before treatment (T0), immediately after stimulation (T1-T10), one month after treatment (T11) and three months after treatment (T12). Results:Compared with group A, VAS scores reduced in groups B and C at T3-T12 (P < 0.05), and reduced more in group C than in group B at T7-T12 (P < 0.05). The average VAS reduction was less in group B than in group C (χ2 = 5.347, P < 0.05). The PSQI and PGIS scores were less in groups B and C than in group A at T12 (P < 0.05), while it was less in group C than in group B (P < 0.05). There was no significant difference among three groups in MR and the incidence of adverse events. Conclusions:rTMS in either frequencies of 5 Hz or 10 Hz may relieve pain, and improve sleep for PHN patients, while 10 Hz rTMS seems more effective in terms of pain and sleep.

RESUMO
To explore the association of nucleotide binding oligomerization domain-like receptor family caspase recruitment domain containing 3 (NLRC3) with prognosis and tumor immunity in patients with stage III colorectal cancer. Methods: Data of 122 patients with stage III colorectal cancer, who underwent radical resection from 2012 to 2013 in Xiangya Hospital of Central South University, were retrospectively collected. The expressions of NLRC3 and CD8+ were examined by immumohistochemical (IHC) staining. The preoperative clinical data were used to obtain neutrophil to lymphocyte ratio (NLR), and the stability of microsatellite was determined. The relationship between NLRC3 and clinicopathological factors was analyzed by χ2 test, and the independent prognostic factors for patients with stage III colorectal cancer were determined by COX regression model. Results: The expression of NLRC3 was significantly associated with CD8+ T cells infiltration (χ2=27.79, P<0.01), NLR (χ2=6.35, P<0.05), lymph node metastasis (LN) (χ2=10.12, P<0.01) and microsatellite stability (χ2=6.05, P<0.05). NLRC3 (OR=0.066, 95% CI 0.020 to 0.218), vascular emboli (OR=3.119, 95% CI 1.547 to 6.286) and NLR (OR=5.103, 95% CI 2.465 to 10.563) had an effect on overall survival (OS) for patients with stage III colorectal cancer (all P<0.05). In addition, NLRC3 (OR=0.144, 95% CI 0.055 to 0.377), vascular emboli (OR=3.589, 95% CI 1.859 to 6.932) and NLR (OR=2.939, 95% CI 1.509 to 5.723) also had an effect on disease-free survival (DFS) for patients with stage III colorectal cancer (all P<0.05). Conclusion: NLRC3, intravascular emboli and NLR are independent prognostic factors for patients with stage III colorectal cancer. NLRC3 might be a good prognostic factor for patients with stage III colorectal cancer due to its capacity of inhibiting systemic inflammation and promoting local anti-tumor immunity.

Objective To investigate the effect of attention training on cortical activation area and lateralization index in interference ef-fect of dual-task paradigm as the poststroke nonfluent aphasiacs processing the Chinese character tasks. Methods 20 cases with nonfluent aphasia after stroke were divided into the training group and the control group, who accepted attention training and cognitive training respec-tively, 30 min a time, 5 times a week, for 4 weeks. They were investigated the cortical activation area and lateralization index caused by in-terference effect of dual-task paradigm under block design. Results The right inferior frontal gyrus, bilateral parietal and cerebellar cortex were activated before training in both groups, and more activated after attention training, but no change after cognitive training. Lateraliza-tion index suggested that the right brain was more activated before training, while the left side was activated after attention training, but no change after cognitive training. Conclusion The right inferior frontal gyrus, bilateral parietal and cerebellar cortex are very important in solv-ing the dual task interference in the attention stage, and they are activated after attention training. It indicates that attention training makes a significant functional reorganization on Chinese character processing in poststroke nonfluent aphasiacs.

@#Objective To explore the influence of attention training on Chinese character processing capability in poststroke nonfluent aphasiacs. Methods 60 stroke patients with nonfluent aphasia and cognition dysfunction were divided into control group (n=30) and experimental group (n=30). The trainings (attention training and cognition training) were respectively 30 minutes each time, 5 times each week for 4 weeks. The change of reaction time and error rate were compared before and after they were performing the orthographic, semantic and phonological tasks. Results In the dual-task paradigm the change of reaction time and error rate in orthographic and semantic tasks of the experimental group were all higher than the control group (P<0.001). But there was no difference between the two groups in the phonological task (P>0.05). In the single task paradigm there was no difference between the two groups (P>0.05). Conclusion 1. Attention training can improve the processing capacity significantly in orthographic and semantic tasks in the dual-task paradigm because the volume and distributive ability of attention improve significantly. 2. Attention training can't improve the processing capacity in phonological tasks in the dual- task paradigm because reading aloud and judging are required to process the vowel simultaneously. So that the competion intensifies and it is more difficult to finish the task. 3. In the single task paradigm, there is no significant difference between the influence of the two trainings in poststroke nonfluent aphasiac because the single task needs little attention and the change in the control group is enough.

RESUMO
<p><b>OBJECTIVE</b>To explore the predictive factors of sensitivity to preoperative concomitant radiochemotherapy for the local mid-low advanced rectal cancer in order to guide the individualized therapy.</p><p><b>METHODS</b>Clinicopathologic data of 44 patients with local mid-low advanced rectal cancer receiving preoperational concomitant radiochemotherapy were retrospectively analyzed. Expression of epidemical growth factor receptor (EGFR) in biopsy specimen was detected with SP immunohistochemistry (IHC). Downstaging of tumor TNM stage and tumor regression grade (TRG) after radiochemotherapy were used as the standards of sensitivity to preoperational concomitant radiochemotherapy. Association of EGFR expression and pathological change with clinicopathological data before radiochemotherapy (gender, age, pathological type, tumor TNM stage, serum CEA, CA199, radiation method, etc) was analyzed.</p><p><b>RESULTS</b>Percentage of downstaging of tumor TNM stage and 3-4 TRG in patients with negative or weak positive EGFR expression was significantly higher as compared to those with strong and moderate positive EGFR expression [86.7% (13/15) vs. 30.4% (7/23), P<0.01; 80.0% (12/15) vs. 8.7% (2/23), P<0.01]. Percentage of downstaging of tumor TNM stage and 3-4 TRG in patients with tubular adenocarcinoma was significantly higher as compared to those with mucous adenocarcinoma [61.8% (21/34) vs. 10.0% (1/10), P<0.01; 47.1 (16/34) vs. 0 (0/10), P<0.01]. EGFR expression was not associated with pathological type (P>0.05). Sensitivity to preoperative concomitant radiochemotherapy was not associated with age, gender, tumor stage, tumor differentiation, serum CEA, serum CA199 and radiation method (all P>0.05).</p><p><b>CONCLUSIONS</b>Pathological type and EGFR expression level may be two independent predictive markers of sensitivity to preoperative concomitant radiochemotherapy for patients with rectal cancer. Patients with tubular adenocarcinoma or low EGFR expression in tumor tissue may be more sensitive to concomitant radiochemotherapy.</p>

Results and Conclu-sion The tasks activated the right inferior frontal gyrus, bilateral parietal and cerebellar cortex. The laterality index showed that the left brains were more active in the tasks.
RESUMO
Objective To explore the effects and mechanism of repetitive transcranial magnetic stimulation (rTMS) applied to the right Broca's homologue of stroke patients with non-fluent aphasia.Methods One stroke patient with non-fluent aphasia received rTMS at 1 Hz and another received the same treatment at 10 Hz.The western aphasia battery (WAB) and functional magnetic resonance imaging (fMRI) were used to evaluate their language function before and after the intervention.Results After treatment,language function in both patients had improved significantly.The aphasia quotient (AQ) score of patient 1 had improved from 37.2 to 66.6,and the AQ score of patient 2 had improved from 36.2 to 60.8.Before treatment,patient 1's activated brain areas during a vocabulary reading task were the left anterior central gyrus and the left gyrus frontalis medius.After the 1 Hz rTMS treatment the activated brain areas were the left medial surface of the lobus frontalis,the left gyrus frontalis inferior,the left prefrontal area,the left preinsula,the left lobulus parietalis inferior,and the left middle/inferior temporal gyrus.Before the 10 Hz rTMS treatment,patient 2's activated brain areas with the same vocabulary reading task were the bilateral medial surface of the temporal lobe,and the bilateral anterior central gyrus.After treatment the bilateral medial surface gyrus,the frontalis medius and lobus frontalis,the right gyrus frontalis inferior,the left prefrontal area,the bilateral lobulus parietalis superior,and the right superior/middle temporal gyrus were activated.Conclusion rTMS can significantly improve language function in stroke patients with non-fluent aphasia.Patients with smaller lesions in the left hemisphere language area can achieve hemisphere function restructuring.Larger lesions in the left hemisphere language area will probably yield bilateral restructuring in both hemispheres.
