ABSTRACT

Objective:To explore the application of Tongdu Tiaoshen acupuncture in patients with hemiplegia after stroke.Methods:Randomized controlled trial. A total of 70 patients who met the inclusion criteria for post-stroke hemiplegia in our hospital from January 2020 to December 2021 were divided into two groups, with 35 cases in each group, according to the random number table. The control group was given conventional treatment combined with rehabilitation exercise therapy, and the observation group was given Tongdu Tiaoshen acupuncture on the basis of the above, and both groups were treated continuously for 1 month. Compare of the two groups Fugl-Meyer Assessment (FMA), Modified Ashworth Scale (MAS), National Institutes of Health Stroke Scale (NIHSS), Activity of Daily Living (ADL) score; Brunnstrom stage method was used to assess the patient's motor ability, and Holden walking function grade was used to assess the patient's walking ability. The activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time(TT), and serum fibrinogen (FIB), D-dimer (D-D), plasminogen activator inhibitor 1 (PAI-1) levels were observed by ELISA. Adverse events were recorded and clinical efficacy was evaluated.Results:The total effective rates of the observation group and the control group were 97.14% (34/35) and 77.14% (27/35), respectively, and the difference between the two groups was statistically significant ( χ2=6.25, P=0.012). After treatment, the scores of FMA and ADL in the observation group were significantly higher than those in the control group ( t values were 9.23 and 9.54, respectively, P<0.01), the MAS and NIHSS scores were significantly lower than those in the control group ( t values were 10.23 and 11.97, respectively, P<0.01). After treatment, the distribution of patients in Brunnstrom stage Ⅴ and Ⅵand Holden functional walking stage Ⅳ and Ⅴ in the observation group was significantly higher than those in the control group ( χ2 values were 11.96 and 11.27, respectively, P<0.05). After treatment, APTT, PT and TT in the observation group were significantly longer than those in the control group ( t values were 10.37, 13.57 and 6.54, respectively, P<0.01); serum FIB, D-D and PAI-1 levels were significantly lower than those in the control group ( t values were 12.85, 11.94 and 27.39, respectively, P<0.01). No adverse reactions occurred in both groups. Conclusion:The treatment of post-stroke hemiplegia with Tongdu Tiaoshen acupuncture can improve the effect of clinical treatment and the ability of daily life, neurological function, limb function, movement and walking ability, and stabilize the clotting state.

ABSTRACT

Objective:To investigate the relationship between telomere length of bone marrow mononuclear cells and prognosis of patients with acute myeloid leukemia (AML) who received allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:Telomere length of bone marrow mononuclear cells before transplantation, after transplantation and before donor mobilization as well as information related to follow-up of 33 AML patients who received allo-HSCT in the Affiliated Hospital of Guizhou Medical University between June 2020 and June 2021 were retrospectively analyzed. Telomere length was detected by using telomeric terminal restriction fragment (TRF) method. Telomere length was compared among patients with different prognoses. The recurrence within 1 year was treated as the gold standard and receiver operating characteristic (ROC) curve was used to analyze the effect of telomere length before transplantation or before donor mobilization in the judgement of the recurrence within 1 year after transplantation. The patients were stratified according to the optimal threshold value of telomere length for patients or donors, and Kaplan-Meier method was used to compare the progression-free survival (PFS) of patients with different stratification, and log-rank test was performed.Results:The median age of 33 patients was 34 years (14-61 years), and there were 17 males and 16 females; 31 patients were initially diagnosed with AML, 1 patient transferred from myelodysplastic syndrome (MDS) to AML, and 1 patient transferred from chronic granulocytic leukemia (CML) to AML; 14 received identical sibling transplantation and 19 received haploidentical sibling transplantation. The median age of the donors was 30 years (20-65 years), including 24 males and 9 females. Telomere length of bone marrow mononuclear cells before mobilization in 33 donors was longer than that in patients before transplantation (33 cases) and at +30 d after transplantation (31 cases) [(6.67±0.31) kb, (6.40±0.33) kb, (6.48±0.33) kb, respectively; all P < 0.05], and the difference between patients before and at +30 d after transplantation was not statistically significant ( t = 0.89, P = 0.378), and the telomere length of bone marrow mononuclear cells in 11 patients +180 d after transplantation was (6.66±0.18) kb. The incidence of acute graft-versus-host disease (aGVHD) after transplantation was 45.5% (15/33), the incidence of infection with clear imaging and pathogenic basis was 39.4% (13/33), the mortality rate within 1 year after transplantation was 3.0% (1/33), and the recurrence rate within 1 year after transplantation was 15.2% (5/33). There were no statistically significant differences in telomere length of donor pre-mobilization bone marrow mononuclear cells between the groups with and without aGVHD and between the infected and non-infected groups (all P > 0.05).Compared with patients who had not relapsed within 1 year after transplantation, telomere length of donor pre-mobilization bone marrow mononuclear cells was shorter in patients who relapsed within 1 year after transplantation [(6.39±0.19) kb vs. (6.72±0.30) kb, t = -3.23, P = 0.011], telomere length was longer in patients before transplantation [(6.75±0.16) kb vs. (6.35±0.36) kb, t = 4.17, P = 0.001]. ROC curve analysis showed that the optimal threshold values for telomere length of pre-transplantation and donor pre-mobilization bone marrow mononuclear cells were 6.48 and 6.42 kb, respectively for patients who relapsed within 1 year after transplantation. PFS in patients with pre-transplantation bone marrow mononuclear cells telomere length < 6.48 kb was better than that in patients with telomere length ≥ 6.48 kb ( P = 0.003); PFS in patients with pre-mobilization bone marrow mononuclear cells telomere length>6.42 kb was better than that in patients with telomere length ≤ 6.42 kb ( P < 0.001). Conclusions:In allo-HSCT for AML, patients have an increased risk of relapse within 1 year after transplantation when their pre-transplantation bone marrow mononuclear cells telomere length is long and the donor bone marrow mononuclear cells telomere length is short.

ABSTRACT

Objective To investigate the correlation of miR-181a and miR-181b with fucosyltransferase FUT1, the functional mechanism was elucidated in a colorectal cancer ( CRC).Methods It collected 32 pairs of tissue samples , 18 males and 14 females in the first affiliated hospital of Dalian Medicinal University, from March 2014 to January 2016.The expression of miR-181a and miR-181b was detected by RT-PCR in CRC tissues , adjacent tissues , serum of colorectal cancer patients and healthy people, and CRC cell lines SW620 and SW480 with differently metastatic ability.The relationship of FUT1 and miR-181a, miR-181b expression were verificated by Pearson's correlation curve.FUT1 was identified the target of miR-181a and miR-181b by Network prediction softwares ( TargetScan Human 7.1, microRNA.org and Starbase v2.0) and luciferase assay.The effects of miR-181a and miR-181b expression on the proliferation, migration, invasion and angiogenesis of SW 480 and SW620 cells were further detected by CCK8, wound healing, transwell and tube foramtion assays.T-test was used for comparison between two independent samples , and one-way anova was used for comparison between multiple samples . Pearson correlation coefficient was used for correlation analysis .Results The levels of miR-181a and 181b in CRC tissues were much lower than in tumor-adjacent tissues (3.12 ±1.88 vs 6.44 ±2.32, t=11.74;3.16 ± 1.77 vs 5.52 ±2.45, t=3.24 ;P<0.05).The levels of miR-181a and 181b in serum of colorectal cancer patients were much lower than in healthy people (1.32 ±0.25,2.57 ±0.48,t=10.26;0.91 ±0.14,1.63 ± 0.29,t=5.19;P<0.05 ) .The levels of miR-181a and miR-181b in SW620, SW480 CRC cells were detected to be much lower than in normal colorectal epithelial cells [(0.65 ±0.10, 0.50 ±0.09) vs 1.0;(0.60 ±0.12,0.42 ±0.03)vs 1.0;t=3.08, P<0.05].FUT1 was highly expressed in CRC tissues and SW620 (t=5.23, P<0.05).Based on the network prediction softwares and luciferase assays , FUT1 was the common target of miR-181a and miR-181b.Over expression of miR-181a or miR-181b inhibited FUT1 level and attenuated the capacity of cell migration , invasion and proliferation in SW 620.Down-regulation of miRNAs in SW480 increased FUT1 expression and promoted the capability of cell migration , invasion and proliferation.Downregulation of the two miRNAs attenuated the capability of cell invasion in SW 480, which was blocked by the reductive FUT1.Conclusion MiR-181a and miR-181b mediated the progression of CRC cells by targeting FUT1.

ABSTRACT

BACKGROUND:Bone marrow mesenchymal stem cels can secrete a variety of factors in the local lesion, and these factors can promote cel proliferation and inhibit cel apoptosis. OBJECTIVE: To observe the curative effect of bone marrow mesenchymal stem cel transplantation on the aging heart of rats and to explore the possible mechanism of action. METHODS:Thirty Sprague-Dawley rats were randomized into three groups: normal blank group, model group and treatment group. Aging models were made in the latter two groups by injection of D-galactose. Rats in the treatment group were given alogeneic bone marrow mesenchymal stem cel injection, once a week, totaly four times. At 1 week after final injection, the heart tissues were sliced into sections to observe the pathological changes using hematoxylin-eosin staining. Western blot assay was used to detect the expression of basic fibroblast growth factor in the heart tissues. Real-time PCR was used to measure the expression of p53 mRNA in the heart tissues. RESULTS AND CONCLUSION:Bone marrow mesenchymal stem cel transplantation could improve the pathological morphology of the aging heart. Compared with the model group, the expression of basic fibroblast growth factor in the heart tissues was significantly higher in the treatment group (P < 0.05), but the mRNA expression of p53 was lower (P < 0.05). It is speculated that bone marrow mesenchymal stem cels can interact with heart cels to secrete basic fibroblast growth factor and reduce p53 mRNA expression, thereby playing a curative effect on the aging heart.

ABSTRACT

Objective:To examine the features of multislice spiral computed tomography (MSCT) in micropapillary-predominant lung adenocarcinomas to improve the understanding of this type of lung cancer. Methods:The MSCT features of 18 cases with micro-papillary-predominant lung adenocarcinoma (micropapillary component>50%) confirmed by histopathology were analyzed retrospec-tively. Results:Among the 18 cases of lung cancer, 1 was diffuse, 3 were central, and 14 were peripheral lung cancer (PLC). The size of the adenocarcinomas in the 14 PLC cases ranged from 1.3 cm to 8.5 cm, with an average of 3.56 cm, including the size of 8 cases greater than or equal to 3 cm. Among the 18 cases, 13 were lobulated, 9 showed spicule signs, 7 showed pleural indentation signs, 5 had pleural adhesions, 1 had bronchial truncation (i.e., cut-off sign), and 4 were surrounded by obstructive inflammation. In addition, calcifi-cation was observed in one case, uneven density in two large lesions, air bronchus sign in four, and solid and ground-glass mixed densi-ty in two. Among the total number of cases, a variety of the measurable enhanced CT values (ΔCT) of lesions were found in 16, ranging from 13 HU to 80 HU, with an average of 47.5 HU, of which 15 were cases ofΔCT≥15 HU and 15 were cases ofΔCT≥20 HU. Pleu-ral thickening was observed in two cases with pleural effusion, and pleural metastasis in one case was confirmed by histopathology. One case with pleural effusion suffering pleural metastasis was confirmed. Ground-glass density nodules in both lungs were observed in one case, with a few bilateral pleural and pericardial effusions. Eight cases had mediastinal or hilar enlarged lymph nodes with uneven density enhancement, and lymph node metastasis was pathologically confirmed in six cases. Lymph node metastasis was found in four cases, but no apparent enlargement of lymph nodes in MSCT was observed. Conclusion:Micropapillary-predominant lung adenocarci-nomas were common in non-smoking elderly female patients, whose lung cancer cases were mostly PLC. The typical features of PLC include lobulation, spicule, and pleural indentation signs. Solid density ranked first in the PLC cases, with evident enhancement and high rate of lymph node metastasis.

ABSTRACT

BACKGROUND:Bone marrow mesenchymal stem cels can differentiate into renal tubular epithelial cels. It is speculated that mesenchymal stem cels may have a therapeutic role in chronic renal dysfunction. OBJECTIVE: To study the effect of bone marrow mesenchymal stem cels on the aging kidney of rats and its possible mechanism. METHODS: Aging models were established in rats. Rat bone marrow mesechymal stem cels cultured in vitro were labeled by 5,6-carboxyfluorescein diacetate, succinimidyl ester, and then injected into the ratsvia the tail vein. Under a fluorescence microscope, the cellhoming was observed. The contents of urea nitrogen and creatinine in serum of rats were tested by automatic biochemical analyzer. The overlaying of blue fluorescent 2-(4-amidinophenyl)-6-indolecarbamidine dihydrochloride and the specific protein of red fluorescent tubular epithelial cels (keratin protein) was detected by indirect immunofluorescence and computer image stacking technique. RESULTS AND CONCLUSION: Bone marrow mesenchymal stem cels could arrive the kidney of rats. Compared with the model group, the contents of urea nitrogen and creatinine in serum were decreased in the treated group (P < 0.05). The treated group showed a smal amount of double positive cels. These findings indicate that rat bone marrow mesenchymal stem cels may differentiate into renal tubular epithelial cels, which may be one of mechanisms that improve the aging kidney of rats.

ABSTRACT

Objectives To study the effect of mesenchymal stem cells on the aging rat kidney and to explore the underlying mechanism. Methods Rat models of senile kidney were built with hypodermic injection of D-galactose daily. Injections of MSCs of 3 × 10<'6>were given to each rat through vena caudalis and CFSE was used as a tracing label to detect the distribution of MSCs in vivo. After 24 h, rats were dissected and their kidneys were frozen for section. MSCs were observed with Fluophot and quantitative analysis of the various parameters of kidney was performed under a light microscope with B12000 image analysis system.The contents of superoxide dismutase (SOD) and malondialdehyde (MDA) in serum and kidney were measured wtih hydroxylamine and chromatometry. The expression of VEGF and P16 mRNA in kidney tissue was detected with real-time PCR and Western blotting. Results MSCs was found homing in the rat kidney,and the glomerular size, sklerosis-rate and the average cell count of glomerulus in the treated group were different from those of the model group (P<0.05). In the treated group, the activity of SOD was significantly higher and the content of MDA was lower in serum and kidney than that in the model control group (P<0.05). The expression of VEGF mRNA and protein in the kidneys of MSCs group increased significantly as compared with the model group (P<0.05). The expression of P16 mRNA and protein in the kidney of MSCs group decreased significantly compared with the model group (P<0.05). Conclusion MSCs can increase the expression of VEGF while decrease the expression of P16, so as to play a key role in the anti-aging on rat kidney.

ABSTRACT

Objective To investigate the treatment of open vertebreplasty for unstabilized thoracic-lumbar fracture. Methods From September 2003 to May 2007, there were 31 patients of thoracic-lumbar burst fracture who had undergone operation and had been followed. According to the Denis classification, all the patient were burst fracture with the involvement of middle column. All of them were undergone posterior short segment transforminal interbody fusion and vertebreplasty filled with phosphate calcium bone cement. Results All of 31 patients had undergone operation successfully. The interbody were removed when fracture healed. There was no loss of vertebral height, no degenerative change of adjacent segment. They were followed for 9~35 months, the average was 24.2 month. 2 of 31(6.4%) were found collapse of the fracture vertebrae, 1 was found kyphosis and failure fusion, which led another operation. The reason may be the severe burst of vertebrae, insufficient filling of phosphate calcium bone cement or bearing weight early stage. Of all other patients, CT scan showed sufficient decompression of fracture vertebraes, retained height of fracture vertebraes and no collapse. There was no obvious difference between height of fracture vertebrae and normal vertebrae (P0.05). The loss of correction of kyphosis was not obvious. Conclusion posterior short segment transforminal interbody fusion and vertebreplasty filled with phosphate calcium bone cement is a effective treatment for unstabilized thoracic-lumbar fracture. The pain is relieved after operation, patient can exercise on the ground in the early stage, and the quality of life is improved.
