ABSTRACT

ObjectiveTo compare the functional connectivity of brain networks in stroke patients with upper limb motor dysfunction during unilateral or bilateral upper limb movement using functional near-infrared spectroscopy (fNIRS). MethodsFrom April to June, 2021, 40 stroke patients with upper limb motor dysfunction in Department of Rehabilitation Medicine, Huashan Hospital, finished unilateral (affected) and bilateral upper limb movement. Eight-minute fNIRS data were collected before and after movement, and the functional activities and connectivity of prefrontal cortex (PFC), upper limb and hand functional area (H), primary sensory cortex (S1) were analyzed based on oxygenated hemoglobin. ResultsFunctional activities increased in affected H after unilateral task (t = -3.135, P < 0.05), while the functional connectivity increased between affected H and affected S1, affected H and unaffected S1, and affected S1 and unaffected S1 (|t| > 3.218, P < 0.05). There was no significant difference in the functional activities and connectivity of all the areas after bilateral upper limb task (|t| < 2.385, P > 0.05). The improvement of affected H was more after unilateral task than after bilateral upper limb task (t = 2.026, P < 0.05). ConclusionUnilateral affected upper limb training is more effective on functional activities and connectivity for corresponding brain regions than bilateral task.

ABSTRACT

Objective:To compare the prognosis of fluoroucil combined with cisplatin and paclitaxel combined with cisplatin regimens with concurrent radiotherapy in treatment of esophageal squamous cell carcinoma.Methods:A total of 120 patients with esophageal squamous cell carcinoma who were admitted to Anyang Tumor Hospital of Henan Province from December 2012 to November 2018 were randomly divided into group A and group B by using a random number generator. Group A was given cisplatin combined with 5-fluorouracil, and group B was given cisplatin combined with paclitaxel. Both groups had the same radiotherapy regimen, and both used intensity-modulated radiation therapy (IMRT). Completions of 50 Gy radiotherapy and at least one cycle of chemotherapy were considered to be in line with the plan. Survival data was analyzed in the term of intention-to-treat (ITT) and per-protocol (PP) set.Results:Of the 120 patients, 114 patients were treated and the adverse reactions could be evaluated, including 55 cases in group A and 59 cases in group B. The incidence of grade Ⅲ-Ⅳ leukopenia in group B was higher than that in group A [49.2% (29/59) vs. 25.5% (14/55)], and the difference was statistically significant ( χ2 = 6.805, P = 0.012), and there were no statistical differences in the other adverse reactions between the two groups (All P > 0.05). A total of 113 cases can be analyzed for survival. According to ITT analysis, the median progression-free survival (PFS) time in group A and group B was 28.0 months (95% CI 15.5-34.5 months) and 27.0 months (95% CI 17.0-41.0 months), the median overall survival (OS) time was 28.0 months (95% CI 15.8-34.2 months) and not reached, the differences were not statistically significant (both P > 0.05). According to PP analysis, the median PFS time in group A and group B was 28.0 months (95% CI 15.8-34.2 months) and 29.0 months (95% CI 14.9-45.1 months), the median OS time in group A and group B was 28.0 months (95% CI 3.7-52.3 months) and not reached, the differences were not statistically significant (both P > 0.05). Conclusions:The fluorouracil combined with cisplatin regimen and paclitaxel combined with cisplatin regimen with concurrent radiotherapy have similar PFS and OS time in treatment of esophageal squamous cell carcinoma, the adverse reactions are different, but they are all tolerable. In individualized clinical practice, the toxicities and costs of the two regimens can be comprehensively considered.

ABSTRACT

Objective To study the effect and toxicity ofgefitinib combined with selected radiotherapy in the treatment of patients with advanced non-small-cell lung cancer (NSCLC). Methods From March 2006 to February 2009,10 of 13 advanced NSCLC patients who got benefit from gefitinib were enrolled to treatment group (gefitinib concurrent selected radiotherapy) and control group (gefitinib only), with 5 cases in each group. The response was evaluated as progression free survival (PFS) and overall survival (OS).Results No patient got complete remission (CR). Ten of 13 patients got partial remission (PR) and stable disease (SD). The 1 year and 2 years survival rate was 53.8%(7/13) and 46.2%(6/13) respectively. The median PFS in treatment group and control group was 24 months and 8 months respectively(P= 0.0019). The median OS was 32 months and 10 months respectively (P= 0.0062). The main toxicities were reversible skin rash and diarrhea,and 3 patients developed asymptomatic radiation pulmonary fibrosis. Conclusions Gefitinib combining with selected radiotherapy is effective and tolerated in patients with advanced NSCLC. It may prolong PFS and OS. It may be a rational choice for the standard and individualized treatment of NSCLC.

ABSTRACT

Objective To explore the effect of glutamine on changes in the expression of intercellular adhesion molecule-1(ICAM-1)and E-selectin and the characteristics of pulmonary vascular endothelial cells(VECs)in sepsis rats.Method Totally 56 Sprague-Dawley rats were randomly divided into three groups:a control group,a sepsis group and a treatment group.All experiments were performed at the animal research center at Sun Yat-sen University in Guangzhou.Sepsis was induced by injecting 4 mg/kg lipopolysaccharide(LPS).The treatment group was injected with 4 mg/kg LPS and 0.3 g/kg glutamine.The control group was not injected with either LPS or glutamine.The rats were killed at 6,12 or 24 h after treatment and pulmonary tissue samples were obtained.The expression of ICAM-1 and E-selectin in VECs was detected by reverse transcription-polymerase chain reaction and immunohistochemistry.Apoptosis of VECs lung tissue was analyzed by Hoechest-33258 staining.The ultramicrostructure of VECs was observed under an electron microscope.Data were analyzed using analysis of variance using SPSS 13.0.Results At 6,12 and 24 h,the expression of ICAM-1 and E-selectin was significantly higher in the sepsis group(relative expression;ICAM-1:0.0864 ± 0.0101,0.141 ± 0.0147 and 0.1677 ± 0.0127,respectively;E-selectin:0.1535 ±0.0180,0.0811 ±0.0107 and 0.0505 ± 0.0031,respectively)compared with the control group(ICAM-1:0.021 ±0.0032,0.0228±0.0042 and 0.0204±0.0059,respectively;E-selectin:0.0423 ±0.0108,0.0412 ±0.0066 and 0.0418 ±0.0092,respectively)(all:P<0.01).Glutamine treatment significantly decreased(P<0.01)the expression of ICAM-1(0.0646±0.0136,0.1202±0.0143 and 0.1378 ±0.0085,respectively)and E-selectin(0.1071 ±0.0189,0.0628±0.0088 and0.0463±0.0049,respectively)at all time points compared with the sepsis group.However,the expression of ICAM-1 and E-selectin remained significantly higher than that in the control group(all:P<0.05).There were similar changes in the expression of pulmonary ICAM-1,E-selectin mRNA and the results of VEC apoptosis.Electron microscopy confirmed these findings.Conclusions The expression of ICAM-1 and E-selectin was significantly increased in sepsis rats,leading to necrosis and apoptosis of VECs,and the onset of acute lung injury.Glutamine had a protective effect in VECs against lipopolysaccharide-induced sepsis.

ABSTRACT

AIM: To investigate the protective effect of ulinastatin on rats with hemorrhagic shock. METHODS: A prospective, controlled animal study was designed. The model of hemorrhagic shock in rats was produced by Chaudry method. After 60 min, rats were resuscitated by transfusion of shed blood and normal saline, but a half of them were treated with ulinastatin. At different time points after reperfusion, the levels of tumor necrosis factor-alpha (TNF-?), interleukin-6 (IL-6), malondialdehyde (MDA) and superoxide dismutase (SOD) in serum were detected. RESULTS: The levels of TNF-?, IL-6 and MDA significantly increased and the activity of SOD decreased. In the ulinastatin-treated groups, the blood pressure and heart rate were obviously improved; the levels of TNF-?, IL-6 and MDA significantly decreased and the activity of SOD had little change after hemorrhagic shock and reperfusion. CONCLUSION: Ulinastatin has a protection effect on rats with hemorrhagic shock by suppressing the production of inflammatory factors and reducing oxidative damage.
