2.Advances in Rehabilitation Therapy for Dysphagia after Stroke (review)
Chinese Journal of Rehabilitation Theory and Practice 2016;22(2):160-163
The rehabilitation therapeutic method of dysphagia after stroke included movement therapy and compensatory technology (including neurodevelopmental therapy), neuromuscular electrical stimulation, surface electromygraphy biofeedback training, non-invasive brain stimulation, balloon ductal dilatation technique, acupuncture and moxibustion, drug, and surgical treatment. The movement therapy and compensatory technology were the basis of therapy and the upward and forward movements of tongue-throat complex were the core of therapy. The combined treatments of early, initiative, individual, and various methods were emphasized, while the nutrition and the preven-tion and cure of aspiration pneumonia of patients should be paid attention to.

AIM To investigate the effect of cisplatin on apoptosis in Scaber cell. METHODS The apoptotic cells were detected by TUNEL,HE,eletronic micrpscopy. RESULTS Treatment of Scaber cells with CDDP resulted in characteristics typical of apoptosis. CDDP induced apoptosis of Scaber cells in time and concentration dependent manner. To further investigate the mechanism of apoptosis induced by CDDP, the expressions and activity of apoptosis associated proteins such as bcl 2, bax and caspase 3 were examined using S P method.The results showed: CDDP caused time and concentration dependent decreases in bcl 2 and increased in bax proteins.CDDP bcl 2 and its translocation to perinuclei and nuclei. The expression of caspase 3 in Scaber cell were determined during apoptosis induced by CDDP. CONCLUSION Our investigetion showed that the apoptosis induced by CDDP is related to the increase of bax protein, and the decrease of bcl 2 protein. and its translocation to perinuclei and nuclei.

Objective To study the association of the expression of bone morphogenetic protein (BMP) antagonist gremlin and vascular calcification in radial arteries of patients with stage 5 of chronic kidney disease (CKD).Methods Radial arteries of 40 patients with stage 5 of CKD were collected as specimens of the study group,which were trimmed off during arterial venous fistula operations.Splenic trabecular arteries were collected as specimens of the control group,which were removed from 38 patients with simple traumatic splenic rupture.All the arteries were examined histologically for calcification with yon Kossa stain.Expressions of gremlin and BMP-2,-7were detected by immunohistochemistry and their serum concentrations were detected by ELISA.Images of histological sections were semi-quantitatively analyzed by Image-Pro Plus 6.0.SPSS 19.0software was used to perform statistical analysis.Results Significantly positive von Kossa stain was found in radial arteries from 12 of 40 patients (30%) in study group,which located in the layer of medial smooth muscle cells.However,there was no obvious positive stain in control group.Additionally,in study group,significant expressions of gremlin and BMP-2 were detected in those radial arteries of positive yon Kossa stain,which also located in the layer of medial smooth muscle cells.Positive correlations were found among gremlin expression level,BMP-2 expression level and yon Kossa stain intensity.However,the BMP-7 expression intensity in arteries of study group was much weaker as compared to control group.Conclusions Both gremlin and BMP-2 may be involved in the process that the smooth muscle cells of radial arteries in patients with stage 5 of CKD phenotypically transform into osteoblast-like cells.However,BMP-7 possibly prevents this process.

Impairment of neuronal mitochondria following hypoxia of brain not only result in nerve cell's energy-deprivation and dysfunction, mitochondria also play key roles in apoptosis of neurons. A central step being the release of cytochrome c (cyt c) across the outer mitochondrial membrane into the cytoplasm through opening of the mitochondrial permeability transition pore. Releasing of cytochrome c induce to downstream consequences of specific caspase activation. The antiapoptotic and proapoptotic members of the Bcl-2 family regulate mitochondrial activities relevant to apoptotic signaling by influencing the realaseing of cyt c.

To explore methods of maintaining the self-renewal capacity of hematopoietic stem cells, inhibiting their overdue differentiation and expanding hematopoietic cells massively, the murine bone marrow stromal cells were coated on microcarriers, then co-cultured with hematopoietic cells from murine bone marrow as group 2 (G2). The G2 contents were wrapped by sodium alginate, then cultivated as group 1 (G1). The only microcarriers coated with stromal cells as group 3 (G3) and the only bone marrow cells as group 4 (G4) were cultivated as control groups. Contrasting observation and microphotograph were performed; the number of total marrow cells, the colony efficiency of CFU-GM and the percentages of CD34(+) cells were determined. Three repeated experiments indicated that the colony efficiency of CFU-GM before culture (G0) were 118.8 +/- 38.1/10(5) marrow cells, and the total outputs of CFU-GM (G0) were 9 501.3 +/- 3 049.0. After culture for two weeks, hematopoietic cells were adhered to or embedded in stromal cells coating the microcarriers, and had formed hematopoietic focus. The colony efficiency of CFU-GM per 10(5) mononuclear cells in group G1, G2, G3 and G4 averaged 30.9 +/- 13.7, 147.3 +/- 66.0, 23.4 +/- 23.1 and 15.9 +/- 8.1, respectively; the total outputs of CFU-GM in group G1, G2, G3 and G4 averaged 273.8 +/- 75.3, 9 424.8 +/- 7 933.7, 419.1 +/- 305.6 and 140.7 +/- 20.7, respectively; the measured CFU-GM output in group G2 was significantly higher than that in group G4, and still significantly higher than the sum of groups G3 and G4 (t = 6.553, t = 5.494; P < 0.05). The percentage of CD34 cells before culture was 10.0 +/- 1.0; after cultuer for two weeks, the percentages of CD34(+) cells in G1, G2, G3 and G4 averaged 4.0 +/- 1.0, 11.0 +/- 1.0, 3.3 +/- 1.5 and 2.2 +/- 0.8, respectively. The percentage of CD34 positive control (3T3 cells) was 17.0 +/- 1.0. This result was consistent with the result of CFU-GM outputs measured. These data suggest that microcarriers coated with stromal cells can perfectly support the ex vivo hematopoiesis at least to four weeks, while hematopoietic cells fixed by alginate are not significantly different from control groups. The hematopoiesis-simulating model of microcarriers is successful, whereas the hematopoiesis-simulating model of alginate macrocarriers can not support the ex vivo hematopoiesis.

BACKGROUNDAwake fiberoptic intubation (AFOI) is usually performed in the management of the predicted difficult airway. The aim of this study was to evaluate the feasibility of dexmedetomidine with midazolam (DM) and sufentanil with midazolam (SM) for sedation for awake fiberoptic nasotracheal intubation.
METHODSFifty patients with limited mouth opening scheduled for AFOI were randomly assigned to two groups (n = 25 per group) by a computer-generated randomization schedule. All subjects received midazolam 0.02 mg/kg as premedication and airway topical anesthesia with a modified "spray-as-you-go" technique. Group DM received dexmedetomidine at a loading dose of 0.5 μg/kg over 10 min followed by a continuous infusion of 0.25 μg·kg-1·h-1, whereas Group SM received sufentanil at a loading dose of 0.2 μg/kg over 10 min followed by a continuous infusion of 0.1 μg·kg-1·h-1. As necessary, since the end of the administration of the loading dose of the study drug, an additional dose of midazolam 0.5 mg at 2-min intervals was given to achieve a modified Observers' Assessment of Alertness/Sedation of 2-3. The quality of intubation conditions and adverse events were observed.
RESULTSThe scores of ease of the AFOI procedure, patient's reaction during AFOI, coughing severity, tolerance after intubation, recall of the procedure and discomfort during the procedure were comparable in both groups (z = 0.572, 0.664, 1.297, 0.467, 0.895, and 0.188, respectively, P > 0.05). Hypoxic episodes similarly occurred in the two groups, but the first partial pressure of end-tidal CO2after intubation was higher in Group SM than that in Group DM (45.2 ± 4.2 mmHg vs. 42.2 ± 4.3 mmHg, t = 2.495, P < 0.05).
CONCLUSIONSBoth dexmedetomidine and sufentanil are effective as an adjuvant for AFOI under airway topical anesthesia combined with midazolam sedation, but respiratory depression is still a potential risk in the sufentanil regimen.
