RESUMO
Objective:To explore the mechanism of epidural scar tissue hyperplasia induced by erythrocyte rupture and release of interleukin-33 (IL-33) after laminectomy in mice.Methods:In the zoological experiment, the operation group (Laminectomy) and the sham operation group were set, and HE staining and Masson staining were performed to test for blood accumulation in the operation area after laminectomy in mice. Then 12 wild-type mice with 6-8 week old were selected and divided into 4 groups: the sham operation group, the operation group (normal saline control), the pure red blood cell intervention operation group, the whole blood intervention operation group. The normal saline (100 mg/kg) was injected into the postoperative area. The red blood cells or whole blood with the same volume were injected into the postoperative area in the pure red blood cell intervention group and the whole blood intervention group. The postoperative recovery of mice in each group was observed. The levels of fibronectin in the postoperative scar tissues of mice in four groups were detected by western blot technology, and the degree of postoperative epidural scar hyperplasia was directly observed by immunohistochemistry. In the cytological experiment, the wild-type mouse erythrocyte normal saline group, the control group of IL-33 knockout mouse erythrocyte normal saline, the wild-type mouse erythrocyte lysis group, and the IL-33 knockout mouse erythrocyte lysis group were set. The levels of IL-33 in the red blood cells of four groups were detected by western blot. Then, a blank wild-type mouse erythrocyte control group, a wild-type mouse relative to the control group (only secondary antibody added to test for non-specific binding), a wild-type mouse erythrocyte group and an IL-33 knockout mouse erythrocyte group (to test for antigen specificity of the primary antibody) were set. Immunofluorescence staining was performed on the erythrocytes of four groups and the level of IL-33 was detected by flow cytometry.Results:HE staining and Masson staining after laminectomy showed that there was blood stasis in the local incision area of mice in the operation group. The epidural scar hyperplasia in the incision area of mice after whole blood or red blood cells intervention was higher, especially in the whole blood intervention group. IL-33 expression was almost undetectable in the wild-type erythrocyte normal saline control group, the IL-33-knockout erythrocyte normal saline control group, and the IL-33-knockout erythrocyte lysis group, while significant IL-33 expression was detectable in the wild-type erythrocyte lysis group. Immunofluorescence staining showed that IL-33 was expressed in and on the erythrocyte membrane of wild-type mice, while non-specific expression of IL-33 or a very small amount of IL-33 was almost undetectable in the other three groups. The immunofluorescence intensities of IL-33 in the four groups were 0.62±0.41, 60.17±4.39, 16.78±7.43 and 0.61±0.03, respectively ( F=281.90, P<0.001). The expression of IL-33 in the erythrocyte group of wild-type mice was the highest ( P<0.05). According to the results of flow cytometry, except for the trace amount of IL-33 detected in the wild-type mouse erythrocyte group, the expression of IL-33 in the other three groups was basically 0. The ratios of fibronectin to β-actin in the modeling area of the four groups gradually increased, and the ratios were 0.79±0.09, 1.26±0.23, 1.79±0.05 and 2.29±0.58, respectively, and the differences were statistically significant ( F=12.86, P=0.002). Fibronectin in the operation area of the three operation groups (normal saline control group, red blood cell intervention group and whole blood intervention group) was significantly higher than that of the sham operation group. The immunohistochemical staining results of fibronectin in the modeling area of the four groups were the same as those in western blot experiment. The average optical density values of fibronectin in each group were 0.09±0.01, 0.18±0.01, 0.22±0.01 and 0.24±0.01, respectively, and the difference was statistically significant ( F= 210.7, P<0.001). Conclusion:There is indeed blood accumulation in the surgical area after laminectomy in mice, and it can aggravate the hyperplasia of epidural scar tissue. Erythrocyte is the main component in blood, and there is a large amount of IL-33 expression in the inner and outer membrane of erythrocyte membrane. The mechanism of promoting the proliferation of epidural scar tissue may be related to the release of IL-33 by erythrocyte lysis.
RESUMO
Objective:To investigate the English learning efficacy and autonomous learning proficiency of postgraduates in universities of Traditional Chinese Medicine (TCM), explore whether there is a correlation between English learning efficacy and autonomous learning ability, and to analyze the influence of English learning efficacy on autonomous learning ability.Methods:A questionnaire survey was carried out to assess the levels of English learning efficacy and English autonomous learning in two levels of belief and behavior among 207 postgraduates in TCM universities. Statistical methods such as independent sample t-test, one-way ANOVA, nonparametric Mann-Whitney U-test, and Kruskal Wallis H-test were applied to analyze the data collected in the questionnaire survey. Results:The average score of subjects' English learning efficacy was 2.82 ± 0.60 (1 ≤ ≤ 5), and the average score of subjects' English autonomous learning ability was 3.24 ± 0.53 (1 ≤ ≤ 5). The scores of their autonomous English learning in the level of belief was significantly higher than those of the level of behavior ( t =14.10, P < 0.001). The scores of autonomous learning ability of subjects in Batch 2020 were significantly lower than those in Batch 2021 ( t = 2.64, P = 0.009). Linear correlation analysis showed that there was a moderately positive correlation between English learning efficacy and autonomous learning ability. Conclusion:The English learning efficacy of postgraduates in TCM universities is at the middle-low level and their English autonomous learning ability is at the middle level. Moreover, their English autonomous learning in the level of behavior underperforms the English autonomous learning in the level of belief, and the English autonomous learning ability decreases with the increase of the grades. In addition, the English learning efficacy has a moderate positive influence on autonomous English learning ability.
RESUMO
Objective:To investigate the expression and clinical relevance of micro RNA (miR)-324-5p in pancreatic cancer tissues, and to explore the effects and potential mechanisms of miR-324-5p on the proliferation and migration of pancreatic cancer cells.Methods:Real-time quantitative PCR was used to detect the expression of miR-324-5p in 34 pairs of pancreatic cancer and adjacent normal tissues resected at Peking University First Hospital from October 2018 to September 2019. The correlations between miR-324-5p expression and clinicopathological characteristics and prognosis of pancreatic cancer were analyzed using data from the Cancer Genome Atlas (TCGA) database. Real-time PCR was used to detect the expression of miR-324-5p in pancreatic cancer cell lines, and PANC-1 cell was used for functional study by overexpressing miR-324-5p via mimic transfection. CCK8 assay was used to evaluate cell proliferation. Both transwell and scratch wound healing assay were used to assess the cancer cell migration ability. Related proteins were detected by Western blot. The potential downstream target genes of miR-324-5p were selected using data from miRNA target genes predicted webs, in combination with functional analysis and their expressional correlation with miR-324-5p.Results:Data from TCGA database showed that the expression of miR-324-5p in tumor tissues was significantly lower than that in normal pancreatic tissues. And low level of miR-324-5p in pancreatic cancer was correlated with poor prognosis. Analysis of 34 pairs pancreatic cancer and adjacent normal tissues showed that miR-324-5p expression in tumor tissues (11.7±2.0) was significantly lower than that in adjacent normal tissues (70.9±14.4), and the pancreatic cancer patients who had the nerve invasion cancer showed low level of miR-324-5p (82.1%, 23/28) was significantly higher than that patients with high level of miR-324-5p (33.3%, 2/6). The expression of miR-324-5p in human pancreatic cancer cell line was also significantly lower than that in normal pancreatic ductal cells. CCK-8 assay showed that the proliferation ability of PANC-1 cell was significantly decreased when miR-324-5p was overexpressed. Transwell and wound healing assays showed that the capabilities of vertical migration and the horizontal movement were significantly inhibited in PANC-1 cell with miR-324-5p overexpressed [(30.11±5.2) and (174.6±27.0) μm, respectively] than those in control groups [(63.6±4.2) and (458.3±22.3) μm, respectively]. Moreover, Western blots showed a significant overexpression of miR-324-5p inhibited epithelial-mesenchymal transition (EMT). According to the data from miRNA target genes prediction and the functional analysis we found KLF3, MGAT3, PBX1 and ZNRF2 were considered as the potential downstream target genes of miR-324-5p.Conclusions:Our results indicated that miR-324-5p is lowly expressed and acts as the tumor suppressor gene in pancreatic cancer, and low level of miR-324-5p is correlated to a higher rate of nerve invasion and poor prognosis. In human pancreatic cancer cell, miR-324-5p may regulate EMT by directly inhibiting target genes such as KLF3, MGAT3, PBX1, ZNRF2, which in turn suppresses cancer cell proliferation and migration.

RESUMO
BACKGROUND: Total hip arthroplasty is a commonly used treatment, but it is difficult to accurately determine the position of the pelvis, which is easy to cause pelvic displacement postoperatively. Additionally, the implant is likely to present with angle deviation, and the precise location and direction of prosthesis is difficult to identify.OBJECTIVE: To study the position and biomechanical characteristics of prosthesis in total hip arthroplasty.METHODS: (1) One male volunteer received CT examination, and a finite element model of the pelvic was established.Three acetabular placement positions (abduction angles of 0°, 20° and 25° combined with anteversion angles of 35°, 15°and 10°) were used to perform total hip arthroplasty, and the peak von Mises stress was detected under a load of 240 N.(2) Six cadaver specimens were collected and received the same interventions with the former experiment, and the stress changes at the bone cortex surrounding femoral shaft and acetabular anterior and posterior wall were measured using resistance strain technology.RESULTS AND CONCLUSION: (1) The peak von Mises stress in the acetabulum at abduction angle of 25° combined with anteversion angle of 10° increased by 25.7%. The peak von Mises stress in the acetabular cup at abduction angles of 0°, 20° and 25° combined with anteversion angles of 35°,15° and 10° was 135.21, 68.3 and 134.2 MPa, respectively.The peak von Mises stress in the lining at abduction angles of 0°, 20° and 25° combined with anteversion angles of 35°,15° and 10° was 6.8, 3.9 and 6.7 MPa, respectively. The peak von Mises stress in the femoral shaft at abduction angles of 0°, 20° and 25° combined with anteversion angles of 35°,15° and 10° was 127.1, 100.2 and 128.2 MPa,respectively. (2) The stress at the bone cortex surrounding femoral shaft and acetabular anterior and posterior wall at abduction angles of 0° and 25° combined with anteversion angles of 35° and 10° was significantly higher than that at abduction angle of 20° combined with anteversion angle of 15°. To conclude, an abduction angle of 20° combined with anteversion angle of 15° is conductive for functional recovery of the joint.

RESUMO
Objective To compare the efficacy of laparoscopic-assisted hemicolectomy with that of open hemicolectomy for right colon carcinoma and to explore the safety and effectiveness of the formor procedure. Methods The clinical data on 46 patients who had undergone laparoscopic-assisted hemicolectomy and 68 patients who had received open hemicolectomy between December 2009 and December 2013 in our department were retrospectively analyzed. Length of postoperative hospital stay, surgical duration, amount of intraoperative blood loss, number of lymph node dissection, time to postoperative anal exhaust, surgical costs, postoperative complications, and survival rate were compared between the two groups. Results There were no statistical differences between the two grounps in gender, age, body mass index, pathological typing, depth of invasion, and total number of lymph node dissection. Length of hospital stay was 6.84 days in the group of laparoscopic-assisted hemicolectomy and 11.72 days in the group of open hemicolectomy , with a statistical significance. Surgical duration and treatment costs did not differ significantly between the two groups; while amount of intraoperative blood loss (76.63 mL vs. 141.5 mL) and time to postoperative anal exhaust differed significanly. Conclusions Laparoscopic-assisted hemicolectomy is safe and effective for treatment of colon cancer , It has advantages of small trauma, rapid postoperative recovery, and a nice-looking surgical incision.
RESUMO
BACKGROUND:The microRNAs are involved in regulation of stem cel proliferation, differentiation and aging. To study the effect of Let-7c, a member of Let-7, on the neural differentiation of bone marrow mesenchymal stem cels provides new ideas for stem cel therapy. OBJECTIVE: To investigate the role of Let-7c in the neural differentiation of bone marrow mesenchymal stem cels. METHODS: The lentiviral vectors of Let-7c-up and Let-7c-inhibition were constructed and transfected into rat bone marrow mesenchymal stem cels. Optimal multiplicity of infection was screened. The cels were divided into non-transfected group, negative control group (transfected with empty virus), transfected enhancement group (transfected with LV-rno-Let-7c-up), transfected inhibition group (transfected with LV-rno-Let-7c-5p-inhibition). Bone marrow mesenchymal stem cels were treated with fasudil as an inducer for triggering the cels to differentiate into neurons. The fluorescence expressed by transfected cels was observed under inverted fluorescence microscope. The expression of neuron-specific markers, neuron-specific enolase and microtubule-associated protein 2, were measured by immunocytochemical method. The mRNA expression of microtubule-associated protein 2 was detected by RT-PCR. The cel viability was determined by MTT method. RESULTS AND CONCLUSION:Under the inverted fluorescence microscope, the cels were successfuly transfected with LV-rno-Let-7c-up and LV-rno-Let-7c-5p-inhibition. Fasudil induced bone marrow mesenchymal stem cels to differentiate into neurons. The transfection efficiency and expression levels of neuron-specific enolase and microtubule-associated protein 2 in the transfected enhancement group were significantly higher than those in the negative control group (P < 0.05), while in the transfected inhibition group, they were lower than those in the negative control group (P < 0.05). These findings indicate that the differentiation percentage of bone marrow mesenchymal stem cels is increased by fasudil after transfection with LV-rno-Let-7c-up, and Let-7c may promote the differentiation of bone marrow mesenchymal stem cels into neurons.
RESUMO
Objective To explore the characteristics of attenuated plaque (AP) in culprit lesions for acute coronary syndrome (ACS) in elderly patients.Methods This study included 166 ACS patients meeting the conditions from Jan.1, 2013 to Sep.31, 2014.Clinical data, vascular lesions determined by coronary angiography and intravenous ultrasound (IVUS)-demonstrated characteristics of culprit plaque, which included presence of AP, maximum attenuation arc, extravascular elastic membrane area, lumen area, plaque area, plaque burden and remodeling index, were recorded.Results Compared with non-elderly group, elderly group had a higher proportion of multiple coronary-artery lesions (50.0％ vs.35.1％, x2=6.525, P =0.038), more attenuation plaques (62.0 ％ vs.45.9％, x2 =4.245, P=0.039), a larger maximum attenuation arc[(142±80)° vs.(115±54)°, t=5.254, P=0.000], larger plaque area[(14.2±3.9)mm2 vs.(12.3 ± 4.1) mm2, t=2.325, P=0.022], more plaque burden [(81.1±14.2)％ vs.(76.4±13.5)％, t=2.025, P=0.042] and higher remodeling index [(1.19±0.17) vs.(1.09±0.13), t=4.245, P=0.031].Conclusions The onset of ACS is more closely related with the unstable plaque in elderly patients, and strengthening the measures for plaque stabilization will be helpful in the prevention and treatment of ACS in the elderly.
RESUMO
BACKGROUND:There is no clear understanding about the effect of let-7f and interleukin-6 (IL-6) on the proliferation of bone marrow mesenchymal stem cels and their relationship. OBJECTIVE: To explore the effects of expression levels of let-7f and IL-6 on the proliferation of bone marrow mesenchymal stem cels and their relationship. METHODS:(1) LV-rno-let-7f-up and LV-rno-let-7f-down were constructed and transfected into bone marrow mesenchymal stem cels of Sprague-Dawley rats, respectively. Then, there were four groups in the study: transfection upregulation group transfected with LV-rno-let-7f-up), transfection inhibition group (transfected with LV-rno-let-7f-down), negative control group (transfected with FU-RNAi-NC-LV), and untransfected group. The expression level of let-7f in each group was detected by qRT-PCR. The proliferation ability of cels and expression levels of IL-6 when let-7f expression was at different levels were detected by MTT, flow cytometry and ELISA. The expression of Cyclin D1 at mRNA and protein levels was detected by qRT-PCR and western blot, respectively. (2) To predict the potential target gene of let-7f, the wild-type/mutant IL-6 3’UTR reporter gene vectors were constructed, and cotransfected with let-7f/let-7f inhibitor respectively into the 293T cels to measure the luciferase. RESULTS AND CONCLUSION: Compared with the negative control group, the proliferative and cloning capacities of cels in the transfection upregulation group were higher; the number of cels was significantly decreased at G1 stage and increased at S stage, and the apoptotic cels were reduced in number (P 0.05). Luciferase activity of cels transfected with wide-type IL-6 3’UTR and let-7f was significantly reduced (P < 0.05). These findings indicate that up-regulation of let-7f can promote the proliferative and cloning capacities of bone marrow mesenchymal stem cels and reduce cel apoptosis, but downrelation of let-7f exhibits an inhibitory effect. Overexpression of IL-6 can suppress the proliferation of bone marrow mesenchymal stem cels, which is considered to be a target gene of let-7f, and let-7f may suppress the expression of IL-6 to promote the cel proliferation.
RESUMO
ObjectiveTo investigate the effects of dopamine D1 receptor (D1R) tool drugs and combined acupuncture and medicine on striatal expressions of D1R and dopamine transporters (DAT) in middle cerebral artery occlusion (MCAO)-reperfusion rats.MethodForty-seven male SD rats were randomly grouped, used to make a model and given corresponding interventions. The materials were taken and fixed six hrs later. Striatal D1R and DAT expressions were detectedby an immunohistochemical method in different groups.ResultThe neurological deficit score was significantly higher in the model group than in the blank group. Electroacupuncture treatment decreased the score significantly (P0.05). DAT expression was significantly down-regulated in the other groups compared with the model group (P0.05).ConclusionCerebral ischemia-reperfusion can result in high D1R and DAT expressions in rat striatum on the ischemic side. Electroacupuncture, D1R antagonists and a combination of the two can significantly down-regulate D1R expression and have a protective effect on the brain. The effects of electroacupuncture and D1R antagonists can not be added to each other. D1R signaling pathway may be one of ways by which electroacupuncture produces a protective effecton the brain.
RESUMO
As a component of traditional Chinese medical therapies, the therapeutic effects of acupuncture for some nervous system diseases have been proven by a large number of clinical and experimental studies. But, the electrophysiological techniques of the commonly used EEG and evoked potentials are still not sufficient to reveal the functional mechanism of acupuncture therapy. The recording technique of microelectrode array (MEA), a kind of electrophysiological technique originated from the overseas biological electrical signal monitoring technique, can be used to record multiple electrical signals of the nervous cells in vivo or in vitro, and maintain the accuracy and stability of the recorded information at the same time, which greatly enriches the means of electrophysiological study. This technique has been already applied in the basic study and clinical treatment abroad, but it is very seldom used in the study of acupuncture field. In order to guide the application of MEA in the research field of acupuncture science, a general survey about the application of MEA technique in vivo was done, and the present situation and prospects of the application of the technique in acupuncture science was briefly analyzed.
RESUMO
BACKGROUND:Cortical electrical stimulation has achieved good effects in treatment of stroke through animal and clinical experiments. OBJECTIVE:To observe the effects of a ful y implanted cortical electrical stimulation device with long time, low intensity and various frequencies stimulation protocols on the neurological function recovery in a rat model of local cerebral infarction. METHODS:The cerebral infarction model was established through middle cerebral artery occlusion in 60 Sprague-Dawley adult male rats. Forty rats with 1-3 points by Bederson scale were detected with magnetic resonance imaging, which was used to confirm cortex infarction and to identify a location for implantation of stimulating electrode over the peri-infarct cortex. Twenty-three rats with cortex infarction were randomly divided into cortical electrical stimulation group (CES group, n=13) and no stimulation group (NS group;n=10). The device was implanted on 6 days after middle cerebral artery occlusion, and the stimulation was given for 16 days. The stimulation program consists of two sessions lasting half an hour each in the morning and in the afternoon respectively. Stimulator delivered biphasic charge balanced pulses (pulse width=200μs) with various frequencies of 50 Hz, 20 Hz and 5 Hz within 10 second blocks and then repeated. The rats of NS group were implanted with the device, but received no electrical stimulation. The behavioral tests, includingforelimb use asymmetry test and foot fault test were performed at 2 and 16 days after implantation. Final y, al of the devices were taken out to test if they were normal y working and al of the rats were sacrificed for hematoxylin-eosin staining, which can reflect the structure of peri-infarct cortex and cellmorphology. RESULTS AND CONCLUSION:There was only one stimulator in CES group cannot normal y work, and the remaining 22 ones worked wel . The skin covered the implanted stimulator was slightly ulcerated in one rat, and the incisions of the other rats were healed wel . Hematoxylin-eosin staining showed clear and intact structure in peri-infarction cortex (i.e., electrodes were implanted at the cortex), neurons arranged in neat rows, with abundant neuronal cytoplasm and clear nucleolus. The glial cells have complete structures, and there was no edema in the intercellular spaces. Foot-fault and forelimb use asymmetry tests showed the improved neurological function in rats of CES group than that of NS group. We designed a ful-implanted cortical electrical stimulator used in cerebral ischemic rats, and established an implanted method with long time, low intensity and various frequencies pulsed electrical stimulation. The results indicated the stimulation pattern in our study is safe and effective, and it can significantly promote functional recovery in local cerebral infarction rats.
RESUMO

RESUMO
Objective To investigate the effect of xuebijing injection applied after abdominal operation on the inflammatory reaction,infection rate,length of stay and hepatorenal function. Methods Sixty patients received abdominal operations were randomly divided into therapeutic group (30 cases) and control group (30 cases). The inflammatory reaction indexes (temperature,heart rate,leucocyte) and hepatorenal function indexes(aminopherase, total bilirubin, creatinine, blood urea nitrogen) were observed in both groups before operation and after operation 3,7 days respectively. The infection rate and length of stay were compared in two groups. Results Temperature and leucocyte post operative 3 days [temperature:(37.0 ± 0.2) ℃ vs. (37.9 ± 0.4) ℃ ;leucocyte: (8.8 ± 1.1 ) × 109/L vs. ( 10.3 ± 1.7) × 109/L, P＜ 0.05] and length of stay in therapeutic group was obviously better than that in control group[ (8.7 ± 1.9 ) d vs. ( 10.9±1.6) d, P ＜ 0.05 ]. The hepatorenal function indexes and infection rate in both groups had no significant difference(P ＞ 0.05). Conclusion Xuebijing injection could significantly palliate the inflammatory reaction after abdominal operation, shorten the length of stay and has no hepatorenal toxicity in short term.
RESUMO
Objective To study the relationship between interleukin-6(IL-6) and the newly diagnosed type 2 diabetes mellitus with Dampness-Heat Encumbering the Spleen syndrome and the relationship between overweight and IL-6. Methods The plasma levels of IL-6 were detected by radio immunoassay in 40 patients with the newly diagnosed type 2 diabetes mellitus (Dampness-Heat Encumbering the Spleen syndrome 10 cases and the deficiency of Qi and Yin syndrome 10 cases)and 10 healthy adults. The changes of body mass index (BMI) and waist-hip ratio (WHR) were observed and analyzed in each group. Results The level of IL-6 in blood plasma of patients with the newly diagnosed type 2 diabetes mellitus were obviously higher than that in normal group (P< 0.01); IL-6 level in patients with Dampness-Heat Encumbering the Spleen syndrome and overweight were obviously higher than those with the deficiency of Qi and Yin syndrome (P< 0.01). Conclusion Interaction between the high level of cytokines and (or) overweight may affect the normal immune function, and promote the development of diabetes, especially in patients with Dampness-Heat Encumbering the Spleen syndrome. The high level of IL-6 may indicate the large possibility of future T2DM and can be considered as a new diagnosis of T2DM syndrome differentiation.
