Objective To observe the effect of robot-assisted upper limb training on the recovery of upper limb motor function after stroke.Methods One hundred patients within one month of suffering a stroke were randomly divided into a control group (50 cases) and a therapy group (50 cases).Both groups were given conventional drug therapy and rehabilitation training,while the therapy group also received robot-assisted training once a day,5 days per week for 12 weeks.The Fugl-Meyer assessment for the upper extremities (FMA-UE),the modified Ashworth scale (MAS) and the modified Barthel index (MBI) were used to evaluate the subjects before the experiment and after 4,8 and 12 weeks of treatment.Results During the treatment,the average FMA-UE scores and the average MBI of both groups increased gradually.The treatment group's averages were significantly better than those of the control group at each time point,except that there was no significant difference in elbow and wrist MAS scores.Conclusion Upper limb robots can be used with acute stroke patients in a clinical setting,and they may be beneficial for improving upper limb function and ability in the activities of daily living.

Objective To compare the short-time effect of 3 different regimens of neoadjuvant chemotherapy (NACT) in patients with FIGO stage Ⅰb2-Ⅱb cervical squamous carcinoma.Methods A total of 50 patients with FIGO stage Ⅰb2-Ⅱb cervical squamous carcinoma were divided into 3 groups:systemic chemotherapy group (n=13) ,trans-arterial chemotherapy group (TAC,n=19) ,trans-arterial chemoembolization group (TACE,n=18) .After 1-3 periods of NACT,all patients received surgical operation.Tumor response and reduction ratio after NACT,side effects,hemorrhage volume in surgery and bad prognostic factors (including intraluminal tumor thrombi,pelvic lymph node metastasis,parametrial involvernent,positive surgical margin,ovary metastasis) of operation sample were statistically analyzed.Results Tumor response,reduction ratio and hemorrhage volume in surgery were significantly better in TAC group and TACE group than those in systemic chemotherapy group (P＜0.05) ,but no significant difference was found between TAC group and TACE group (P＞0.05) .The incidence rate of intraluminal tumor thrombi and lymph node metastasis was lower in TACE group than in systemic chemotherapy group and TAC group,but there was no statistical difference.No difference of parametrial involvement,positive surgical margin,ovary metastasis and side effects was found among 3 groups.Conclusion For stage Ⅰb2-Ⅱb cervical squamous carcinoma,preoperative TAC and TACE have more advantages than systemic chemotherapy.In comparison with TAC,TACE is expected to reduce the incidence rate of bad prognostic factors such as intraluminal tumor thrombi and pelvic lymph node metastasis.

Objective To observe the effects of a decoction of buzhong yiqi in conjunction with rehabilitation training in relieving post-stroke fatigue.Methods A group of 115 stroke patients was enrolled and randomly divided into a simple rehabilitation group and a combination therapy group.Both groups received conventional rehabilitation treatment and appropriate treatment of any primary diseases.In addition,those in the combination therapy group were given a decoction of buzhong yiqi twice daily for a total of 4 weeks.EMG signals,subjective evaluations of fatigue severity,active rehabilitation exercise duration,motor function and ability in the activities of daily living (ADL) were assessed before treatment and after 4 weeks of treatment.The slope of the surface electromyogram's mean power frequency (KMPF) and median frequency (KMF) were used to quantify fatigue.Subjective fatigue severity was estimated using a fatigue severity scale (FSS).The active rehabilitation exercise lasted,on average,90 minutes daily.The Fugl-Meyer assessment (FMA) was used to evaluate motor function and the modified Barthel index (MBI) ADL ability.Results There were no statistically significant differences between the groups before treatment.After 4 weeks of treatment all the outcomes in both groups had improved (except the FSS scores of the simple rehabilitation group).The KMPF,KMF,FSS,exercise duration,FMA scores and MBI scores in the combination therapy group were all significantly better than those in the simple rehabilitation group.Conclusion Taking buzhong yiqi can significantly improve the clinical effects of conventional rehabilitation training on post-stroke fatigue.It helps relieve fatigue,improve active participation in rehabilitation exercise,and also improve motor function and ADL ability.

Objective To investigate the short-term efficacy of compound gargle solution chlorhexidine giuconatie and kangfuxin liquid in treatment of recurrent aphthous ulcer (RAU).Methods Eighty patients clinically diagnosed with RAU were chosen and randomly divided into two groups.Test group 1 (40 cases) and Test group 2 (40 cases) were treated with compound gargle solution chlorhexidine giuconatie and kangfuxin liquid respectively until ulcer has been healed completely to evaluate the difference of two groups in clinical efficacy.Return visit and follow-up visit were conducted 7 days and 30 days after the initial treatment,respectively.Results The analgesic onset time of Test group 1 [(6.24 ± 1.09) min] was shorter than that of Test group 2 [(8.62 ± 1.04) min],with statistically significant difference (P ＜ 0.01).The analgesic maintenance time of Test group 1 [(29.47 ± 3.45) min] was longer than that of Test group 2 [(21.61 ±2.18) min],with statistically significant difference (all P ＜ 0.01).The duration of ulcer of Test groups 1 and 2 was (5.97-± 0.87)days and (4.76 ± 1.14)days,with statistically significant difference (P ＜0.01).Conclusions Compound gargle solution chlorhexidine giuconatie and kangfuxin liquid both have a certain level of clinical efficacy for RAU,with the former featuring shorter analgesic onset time and longer duration and the latter advantageous in promoting RAU healing short-term usage of compound gargle solution chlorhexidine giuconatie and kangfuxin liquid cannot prolong RAU dormancy.

Objective:To evaluate the effect of using a walking support band on the gait of stroke survivors.Methods:Sixty stroke survivors were randomly divided into a walking support band group ( n=20), an ankle foot orthosis (AFO) group ( n=20) and a conventional rehabilitation group ( n=20). All three groups received conventional rehabilitation therapy, while the AFO group members were additionally provided with an ankle-foot orthosis and the walking support band group members received training wearing a walking support band. Before and after 4 weeks of treatment, all three groups were evaluated using three-dimensional gait analysis. Results:A total of 57 patients finished the study. After the interventions, the average step speed, frequency and step length of the three groups had all increased significantly, while the average stride width, the percentage of double stance phase, unaffected and affected side stance phase, and the ratio between unaffected and affected side stance phase had all decreased significantly. After the intervention, the average step speed, frequency and length of the AFO and walking support band groups had increased significantly compared with the conventional rehabilitation group, while the average stride width of the AFO group, and the stride width, the percentage of double stance phase and unaffected side stance phase of the walking support band group had decreased significantly. After the treatment, the average percentages of double stance phase and unaffected side stance phase of the walking support band group had decreased significantly more than in the AFO group.Conclusions:A walking support band can significantly improve the abnormal gait of stroke survivors and is superior to an ankle-foot orthosis when combined with conventional rehabilitation therapy.

Endothelial cell injury is a major contributor to cardiovascular diseases.The 2,3,5,4’-Tetrahydroxystilbene-2-O-β-D-Glucoside (TSG) contributes to alleviate human umbilical vein endothelial cells (HUVECs) injury through mechanisms still know a little. This study aims to clarify the TSG effects on gene expression (mRNA and microRNA) related to oxidative stress and endoplasmic reticulum stress induced by H2O2 in HUVECs. We found that TSG significantly reduced the death rate of cells and increased intracellular superoxide dismutase activity. At qRT-PCR, experimental data showed that TSG significantly counteracted the expressions of miR-9-5p, miR-16, miR-21, miR-29b, miR-145-5p, and miR-204-5p. Besides, TSG prevented the expression of ATF6 and CHOP increasing. In contrast, TSG promoted the expression of E2F1. In conclusion, our results point to the obvious protective effect of TSG on HUVECs injury induced by H2O2, and the mechanism may through miR16/ATF6/ E2F1 signaling pathway.

Objective:To analyze the characteristics and surgical outcomes of Shone′s syndrome in children, and to explore the surgical treatment strategy and technical key.Methods:Retrospective study.Children with Shone′s syndrome treated in the Pediatric Heart Center, Beijing Anzhen Hospital, Capital Medical University from May 2013 to June 2019 were retrospectively analyzed for their baseline characteristics and surgical data.The data were compared by Student t-test. Results:A total of 22 children with Shone′s syndrome were recruited, involving 15 males (68.2%) and 7 females (31.8%). There were 6 cases (27.3%) of complete form of Shone′s syndrome and 16 cases (72.7%) of incomplete form.No deaths were reported.The postoperative mitral valve velocity [(149.7±38.2) cm/s vs.(234.9±34.0) cm/s, t=7.341, P<0.05], left ventricular outflow tract velocity [(202.0±105.0) cm/s vs.(328.6±120.3) cm/s, t=6.575, P<0.05] and aortic arch coarctation velocity [(186.1±60.9) cm/s vs.(347.9±100.8) cm/s, t=7.630, P<0.05]were significantly lower than those of preoperative levels.There were no complications occurred at 1-year follow-up, and 91.7% of the patients were followed up for 3 years, and 80.2% were followed up for 5 years without complications, 2 cases needed reoperation. Conclusions:Surgical treatment of Shone′s syndrome achieved satisfactory outcomes.Early diagnosis and early intervention are beneficial to children with Shone′s syndrome, although they need to be followed up and have the risk of reoperation in the long term.

Objective:This study aims to review two surgical techniques results of the reoperation for left atrioventricular valve(LAVV) failure in repaired atrioventricular septal defect.Methods:All consecutive patients with repaired atrioventricular septal defect(AVSD) who underwent redo-LAVV surgery from 2005 to 2019 were included. Patients with single ventricles, banding, atrial isomerism, and complex associated anomalies were excluded. Univariate analysis included repair and replacement. Data analyzed included number and year of primary AVSD and redo-LAVV operation, morphology of AVSD, mortality, and reoperation, early and long-term survival.Results:There were a total of 28 patients including 7 boys(25%) with age of 114.5 months(63.0-194.5 months). The mean body weight was 28.55 kg(15.5-55.9 kg). There were 11(39.3%) patients with complete AVSD and 17(60.7%) with partial AVSD, and 21(75%) patients with LAVV valvuloplasty(LAVVP), 7(25%) patients with LAVV replacement(LAVVR). The aortic cross clamp time was significantly longer in patients who underwent LAVVR compared to LAVVP[LAVVR 94 min(79-107)min vs. LAVVP 66 min(45-83 min), P<0.05]. The technique of cleft closure with LAVVP 18(87.5%) more than LAVVR 2(28.6%), P<0.05. Conclusion:The postoperative left atrio-ventricular valve(LAVV) regurgitation is the main reason of the reoperation. The technique of cleft closure with LVVR-Repair is favorable. At follow-up, survivors with re-LVVR-Repair have high rates with numerous operations.

Objective    To explore the anatomical characteristics and surgical strategies of atrioventricular septal defect (AVSD) with left ventricular outflow tract (LVOT) stenosis. Methods    The clinical data of 11 AVSD patients with LVOT stenosis who underwent surgeries in our hospital from 2008 to 2019 were retrospectively analyzed, including 6 males and 5 females with a median age of 15.0 (7.6-22.0) years. Results    There were 3 patients of complete AVSD and 8 patients of partial AVSD. Subaortic stenosis resulted from discrete subaortic membrane in 3 patients, diffused subaortic membrane in 4 patients, hypertrophied muscle bundles in 3 patients and distorted valve frame in 1 patient. Among these patients, 5 patients underwent LVOT stenosis and AVSD repairs simultaneously for the first time, 5 patients underwent LVOT stenosis repair for the second time and 1 patient for the third time. No postoperative death occurred. The postoperative LVOT flow velocity decreased dramatically after LVOT stenosis repair compared with preoperative one [449.0 (393.0, 507.5) cm/s vs. 212.0 (183.0, 253.5) cm/s, P<0.05]. Conclusion    Surgical results of AVSD combined with LVOT stenosis are satisfactory, but the restenosis should be paid attention to via long-term follow-up.
