ABSTRACT

@#AIM: To evaluate the efficacy of EX-PRESS drainage device implantation combined with phacoemulsification for chronic primary angle-closure glaucoma(CPACG)with cataract and compare with trabeculectomy combined with phacoemulsification. METHODS: A retrospective case control design was used in this study. The patients underwent combined operation of glaucoma and cataract in the ophthalmology department of our hospital from January 1st, 2017 to January 1st, 2019 were collected and divided into two groups according to different operation methods. The study group(13 cases, 16 eyes)was treated with EX-PRESS drainage device implantation combined with phacoemulsification and intraocular lens implantation. The control group(16 cases, 20 eyes)was treated with trabeculectomy combined with phacoemulsification and intraocular lens implantation. The best corrected visual acuity(BCVA)and intraocular pressure(IOP)at 1wk, 1, 3, 6mo after surgery, central anterior chamber depth(ACD)at before surgery, 1, 6mo after surgery, central corneal endothelial cell count, the duration of operation, length of hospital stays after surgery were compared between the two groups. RESULTS:The demography was matched between the two groups(all <i>P</i> >0.05). The number of eyes with visual improvement was significantly raised 6mo after treatment in study group(<i>Z</i>=-2.066,<i>P</i>=0.039). There were no significant differences in BCVA between two groups 6mo after treatment(<i>Z</i>=-0.319,<i>P</i>=0.765). The IOP of study group at 1wk, 1, 3 and 6mo was significantly lower than that before operation(all <i>P</i><0.001). There were no significant differences in IOP between the two groups(<i>F</i>=0.003, <i>P</i>=0.956). The anterior chamber significantly deepened at 1 and 6mo after operation in two groups respectively(all <i>P</i><0.001). There were no significant differences in ACD and central corneal endothelial cells count between two groups(all <i>P</i>>0.05). The duration of operation was 26.1±4.5min in study group and 31.5±5.1min in control group, which showed significant differences(<i>t</i>=-3.307, <i>P</i>=0.002). The length of stays after surgery was 7.2±1.6d in study group and 7.7±1.5d in control group, and there was no significant difference between the two groups(<i>t</i>=-0.880, <i>P</i>=0.388). One eye EX-PRESS touched the iris in study group. Since the IOP was normal, it didn't receive therapy. In control group, the anterior chamber of 2 eyes was 2 degrees shallow after surgery, which recovered in 1wk by pupil dilation and pressurized bandage. At 6mo point after operation, one eye in each group was treated with one IOP drop to maintain normal IOP. In control group, one case received EX-PRESS drainage device implantation again 12mo later for recurrent glaucoma, another case underwent ciliary body photocoagulation 8mo later. CONCLUSION: EX-PRESS drainage device combined with phacoemulsification is effective in improving visual acuity and controlling IOP for CPACG, and it takes shorten operation time compared with trabeculectomy combined with phacoemulsification.

ABSTRACT

Objective: To observe the therapeutic effect of mild moxibustion on irritable bowel syndrome (IBS) visceral hyperalgesiamodel rats and its regulatory effect on P2X3 receptors in the spinal cord, anterior cingutate cortex (ACC) and thalamic ventral posterolateral nucleus (VPL). Methods: Thirty 8-day-old newborn rats were randomly divided into a normal group (n=6) and a modeling group (n=24) according to the completely random number table method. Rats in the normal group were bred routinely, and those in the modeling group were subjected to preparing IBS chronic visceral hyperalgesia model using colorectal distention (CRD) in stimulation method. Rats successfully modelled were re-divided into a model group, a mild moxibustion group, a P2X3 receptor antagonist group, and a normal saline group according to the completely random number table method with 6 rats in each group. Rats in each group received corresponding interventions from the 37-day old, once a day for 7 consecutive days. Immunohistochemistry and Western blot assays were used to detect P2X3 protein expressions in the spinal cord, ACC and VPL of rats. Results: Under different intensities of CRD stimulation, the abdominal withdrawal reflex (AWR) scores of the model group were significantly increased versus the normal group (all P<0.05); the AWR scores of the mild moxibustion group and the P2X3 receptor antagonist group were significantly reduced versus the model group (all P<0.01). The P2X3 protein expressions in rat spinal cord, ACC and VPL tissues of the model group were significantly increased versus the normal group (all P<0.01); the P2X3 protein expressions in rat spinal cord, ACC and VPL tissues of the mild moxibustion group and the P2X3 receptor antagonist group were significantly reduced versus the model group (all P<0.01). Conclusion: Mild moxibustion can inhibit the P2X3 receptor expressions in the spinal cord, ACC, and VPL tissues of IBS visceral hyperalgesia model rats, which may be the mechanism of mild moxibustion in relieving the central sensitization of rats with IBS visceral hyperalgesia.

ABSTRACT

Objective:To analyze the endoscopic and histological characteristics of Helicobacter pylori ( HP)-negative early gastric cancer (EGC) and high grade intraepithelial neoplasia (HGIN). Methods:Data of patients diagnosed as having EGC or HGIN confirmed by pathology at the Seventh Medical Center of Chinese People′s Liberation Army General Hospital from January 2013 to January 2020 were collected. Patients were included according to the diagnostic criteria of HP-negative gastric cancer, and their endoscopic features and histopathological characteristics were retrospectively analyzed. Results:Among 469 lesions of EGC/HGIN, HP-negative lesions accounted for 2.1% (10/469), which included 3 signet ring cell carcinomas, 3 fundic gland type carcinomas, 1 foveolar adenocarcinoma, 1 HGIN of the cardia, 1 familial adenomatous polyposis with gastric HGIN, and 1 Lynch syndrome with gastric HGIN. The 3 cases of signet ring cell carcinoma were all whitish flat/depressed lesions and commonly seen in the lower part of the stomach (2/3). Most of the 7 cases of differentiated EGC/HGIN were elevated type (5/7) and commonly seen in the upper and middle stomach (6/7). Conclusion:HP-negative EGCs are usually solitary lesions under gastroscopy. Undifferentiated type mostly appears whitish flat/depressed in the lower part of the stomach, while differentiated type appears elevated in the upper and middle part.

ABSTRACT

Objective:To explore the effect of respiratory muscle endurance training on the blood pressure, lung function, respiratory muscle strength and motor capacity of persons with hypertension.Methods:Sixty persons with essential hypertension were randomly divided into an experimental group and a control group, each of 30. The experimental group received 8 weeks of inspiratory resistance training with an intensity of 55% of their maximum inspiratory air pressure (MIP) while the control group had an intensity of 10% MIP with the other training conditions the same as those of the experimental group. Both groups practiced 30 times as a set, two sets a day, 4 days a week. Blood pressure, lung function and respiratory muscle strength were measured before and after the intervention, and motor capacity was measured using the 6-minute walk test (6MWT).Results:After the intervention, the average MIP of the experimental group had increased significantly (to 123.6±13.9 from 83.5±9.8cmH 2O). The average 6MWT time of the experimental group had also improved significantly, but there were no significant differences in any of the control group observations. Conclusion:Eight weeks of respiratory muscle endurance training can improve the inspiratory muscle strength and motor capacity of patients with essential hypertension, but it has no effect on blood pressure or lung functioning.

ABSTRACT

Objective:To explore the relationship between seizure cluster of temporal lobe epilepsy with hippocampal sclerosis (TLE-HS) and cortisol (COR) rhythm, and understand its mechanism from the perspective of neuroendocrine.Methods:Fifty-seven patients with unilateral TLE-HS were recruited from the Qinghai Provincial People′s Hospital from May 1st 2012 to December 31st 2020. According to the history of seizure clusters one month before admission, 27 patients were enrolled in seizure clusters group (SC group), 30 patients were included in without seizures cluster group (NSC group). The clinical characteristics were systematically analyzed and compared between the SC and NSC groups. Plasma COR levels were measured at 8:00, 16:00 and 24:00 (COR8, COR16 and COR0) on the same day, and bilateral magnetic resonance spectroscopy (MRS) diagnosis was performed in two groups. Independent sample t test, chi-square test, repeated analysis of variance, covariance analysis, and multivariate Logistic regression were used for statistical analysis. Results:Time effect, grouping effect and the interaction effect of the time and grouping in the level of COR were statistically significant. Covariance analysis excluded age as an influential factor, COR16, COR0 and the slope of COR8-16 in the SC group [(126.22±19.98) μg/L, (51.63±21.43) μg/L, -7.78±4.54] were higher than the NSC group [(97.70±18.55) μg/L, (31.90±10.73) μg/L, -12.40±4.16], and the difference was statistically significant ( F=5.587, 4.320, 4.013, all P<0.05). The slope of COR0-8 in the SC group (17.11±6.32) was lower than that in the NSC group (20.62±6.54), and the difference was statistically significant ( F=-2.065, P<0.05). There was no significant difference in lateralization of hippocampal sclerosis between the two groups, and there was no significant difference in the ratio of N-acetyl aspartic acid(NAA)/[choline(Cho)+creatinine(Cr)] in the unilateral hippocampal sclerosis zone of the two groups, but the NAA/(Cho±Cr) ratio of the contralateral hippocampus in the SC group (0.71±0.03) was lower than that in the NSC group (0.76±0.06),and the difference was statistically significant ( t=4.999, P=0.029). Multivariate Logistic regression analysis showed that COR16 ( OR=1.328, 95% CI 1.073-1.642, P=0.009), COR8-16 ( OR=3.657, 95% CI 1.404-9.525, P=0.008) were independent risk factors of seizure clusters in TLE-HS. Conclusion:COR rhythm disturbance may be the neuroendocrine basis of seizure clusters in patients with TLE-HS.

ABSTRACT

Objective:To analyze the risk factors for early neurological deterioration(END)in elderly patients with acute ischemic stroke(AIS)after intravenous thrombolysis.Methods:Clinical data of 118 patients with AIS who had received thrombolysis were collected retrospectively.According to the occurrence of END, cases were divided into the END group(n=28)and the non-END group(n=90). Univariate analysis was used to compare general characteristics, clinical data, laboratory test results, TOAST classification, infarct location, and degree of culprit vessel stenosis between the two groups.Multivariate Logistic regression analysis was used to analyze the related factors for END.Results:Univariate analysis showed that the proportion of patients with diabetes mellitus and previous cerebral infarction was higher in the END group than in the non-END group( χ2=4.000 and 8.056, P=0.046 and 0.005). There were significant differences in National Institutes of Health Stroke Scale(NIHSS)score, time from onset to thrombolysis, thrombolysis time, swallowing dysfunction, albumin, leukocyte count, neutrophil count, lymphocyte count, glycosylated hemoglobin(HbA1c), creatinine, total cholesterol(TC), low density lipoprotein cholesterol(LDL-C), high density lipoprotein cholesterol(HDL-C)and lipoprotein(a)levels between the two groups(all P<0.05). There were also significant differences between the two groups in TOAST classification, infarct location and degree of culprit vessel stenosis( χ2=13.109 and 9.509, Z=2.912, P=0.004, 0.023 and 0.004). Multivariate Logistic regression analysis showed that NIHSS score, HbA1c, cardiogenic stroke, degree of culprit vessel stenosis and leukocyte count on admission were independent risk factors for END( OR=1.122, 2.131, 1.965, 1.876 and 1.563, P=0.036, 0.024, 0.028, 0.030 and 0.041). Conclusions:NIHSS score, HbA1c, cardiogenic stroke, degree of culprit vascular stenosis and leukocyte count on admission are independent risk factors for END, which should be closely monitored and managed with well formulated preventive measures in order to improve the prognosis of AIS patients.

ABSTRACT

Objective:To investigate and analyze the correlation between blood pressure and serum creatinine (Scr) and glomerular filtration rate (GFR).Methods:This research was a cross-sectional study, a total of 46792 people over 20 years old with relatively complete data in the health management center of the First Affiliated Hospital of Xinjiang Medical University from January to December 2018 were included as the research subjects, and baseline data of these study subjects were obtained by on-site questionnaire, collection of blood pressure, creatinine and other physiological and biochemical indicators. The subjects were divided into 20-64 years old group and ≥65 years group according to their age; being treated as the continuous variables (systolic blood pressure, diastolic blood pressure, five categories), their blood pressure indicators were analyzed. The F test, t test, χ2 test and logistic regression model were used to analyze the baseline characteristics of Scr level and GFR, as well as the correlation between blood pressure and Scr and GFR. Results:(1) The average Scr level was (72.89±16.84) μmol/L in the study population aged 20-93. The average GFR was (102.17±17.01) ml·min -1·(1.73 m 2) -1. The average Scr of men was higher than that of women, the average GFR of men was lower than that of women (all P<0.001). (2) Among the subjects above, there were 514 cases (1.10%) with abnormal Scr level and 657 cases (1.40%) with abnormal GFR, the incidence of abnormal Scr and GFR was higher in men, subjects with age ≥65 years old, or diabetes, or hypertension (all P<0.05). (3) There were significant differences in Scr level and GFR in subjects with different gender, age, blood pressure and body mass index (BMI) (all P<0.05). (4) With the increase of blood pressure, among the crowd of 24-64 years old, the relative risk of abnormal Scr and GFR in the group with baseline blood pressure ≥180/110 mmHg was 8.434 and 5.168 times higher than that in the group with baseline blood pressure<120/80 mmHg, respectively, after adjusting variables such as sex, age, nationality, BMI, hypertension, diabetes. However, among the crowd of ≥65 years old, only the relative risk in the group with baseline blood pressure of 160-179/100-109 mmHg was statistically significant compared with<120/80 mmHg. Conclusion:The blood pressure is bound up with Scr and GFR in the crowd of 24-64 years old.

ABSTRACT

Objective:To investigate epithelial-mesenchymal transition and to explore the effects of mitochondrial dysfunction and increased expression of TGF-β1 pathway on epithelial-mesenchymal transition (EMT) in pancreatic adenocarcinoma after X-ray irradiation.Methods:Split-dose irradiations of total 40 Gy (2 Gy × 20 and 4 Gy × 10) of 6 MV X-rays were performed on PATU1 988 t cells. The migration of the cells were examined through transwell filter chambers. Real-time PCR was adopted to detect the expression of EMT-related factors E-cadherin, Vimentin, N-cadherin, and MMPs (MMP2 and MMP9), critical subunits of mitochondrial complex I, and TGF-β1. The expression of EMT-related factors and content of TGF-β1 was detected after carbonylcyanide-m-chlorophenylhydrazone(CCCP) treatment. Meanwhile, the migration potential of pancreatic cells was detected after small interfering RNA (siRNA) knockdown of the expression of TGF-β1.Results:After irradiation, the migration capacities of the cancer cells increased ( t=21.90, 35.64, P<0.05). The expression of N-cadherin ( t=4.42, 4.77, P<0.05), Vimentin ( t=4.57, 3.02, P<0.05), MMP2 ( t=7.27, 26.08, P<0.05), and MMP9 ( t=13.26, 7.29, P<0.05) all increased, while the expression of E-cadherin deceased ( t=8.37, 6.77, P<0.05). The expression of TGF-β1 ( t=90.49, 35.17, P<0.05) increased. The expression of TGF-β1 decreased with small interfering RNA, which paralleled the inhibition of the epithelial-mesenchymal transition and migration ( t=38.66, 11.54, P<0.05). Mitochondrial dysfunction was reflected by the decline in the membrane potential ( t=6.94, 29.71, P<0.05) and complex-related subunits. The expression of TGF-β1 ( t=47.93, P<0.05) and EMT-related factors further increased after mitochondrial function was destroyed ( t=16.51, P<0.05). Conclusions:Radiation-induced mitochondrial dysfunction can increase the expression of TGF-β1, which promotes epithelial-mesenchymal transition, and result in the migration of pancreatic cancer cell line.

ABSTRACT

Objective:To investigate the mRNA level of adiponectin in patients with gallstone of Hui and Han nationality in Qinghai Province and its clinical significance.Methods:From August 2017 to August 2018, 108 patients with gallbladder cholelithiasis and 91 patients with other benign diseases who were hospitalized in the Affiliated Hospital of Qinghai University from August 2017 to August 2018 were selected as the research objects. According to gallbladder cholesterol stone and the classification criteria of adult obesity, they were divided into gallstone-obesity group (56 cases), gallstone non-obesity group (52 cases), non gallstone obesity group (48 cases) and non gallstone non obesity group (43 cases). The levels of serum lipid (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), blood glucose (GLU), uric acid and high-sensitivity C protein (hs-CRP) were measured. Meanwhile, the adiponectin mRNA levels in omental adipose tissue and abdominal subcutaneous adipose tissue were detected by real time fluorescent quantitative polymerase chain reaction (qRT-PCR).Results:Compared with non gallstone and non obesity group, the serum TC [(4.57±0.49)mmol/L vs (5.63±0.53)mmol/L, (6.12±0.51)mmol/L, (6.85±0.43)mmol/L], TG [(1.50±0.32)mmol/L vs (2.06±0.33)mmol/L, (2.53±0.39)mmol/L, (2.96±0.34)mmol/L], LDL-C [(2.14±0.35)mmol/L vs (2.65±0.33)mmol/L, (3.05±0.37)mmol/L, (3.54±0.38)mmol/L], uric acid [(188.63±13.52)mmol/L vs (257.69±14.63)mmol/L, (306.96±18.96)mmol/L, (359.96±16.58)mmol/L], hs-CRP [(228.32±18.96)μmol/L vs (298.96±19.96)μmol/L, (354.96±19.96)μmol/L, (405.98±19.47)μmol/L] were increased in gallstone-obesity group, gallstone non-obesity group, non gallstone obesity group ( P<0.05), while the adiponectin mRNA [subcutaneous adipose tissue: (1.76±0.25) vs (1.43±0.23), (0.98±0.23), (0.68±0.29); omental adipose tissue: (2.15±0.29) vs (1.88±0.28), (1.56±0.27), (1.12±0.25)] and HDL-C levels [(2.15±0.11)mmol/L vs (1.79±0.15)mmol/L, (1.42±0.12)mmol/L, (1.15±0.09)mmol/L] were decreased ( P<0.05). Compared with the non gallstone obesity group, the serum levels of TC, TG, LDL-C, GLU, uric acid were increased in the gallstone non obesity group, gallstone obesity group, while the adiponectin mRNA and HDL-C levels were decreased ( P<0.05). Compared with the gallstone non obese group, the serum levels of TC, TG, LDL-C, GLU, uric acid and hs-CRP were increased in gallstone obese group, while the levels of adiponectin mRNA and HDL-C were decreased ( P<0.05). Adiponectin in omental adipose tissue and abdominal subcutaneous adipose tissue was positively correlated with HDL-C and negatively correlated with TC, TG, LDL-C, uric acid and hs-CRP ( P<0.05). Logistic regression analysis showed that low level of subcutaneous adiponectin, omental adiponectin and high level of TG were risk factors for gallstone in non obese population ( OR=2.340, 1.931, 2.784, P<0.05), while low level of subcutaneous adiponectin, omental adiponectin and high level of LDL-C were risk factors for gallstone in obese population ( OR=2.358, 2.596, 2.115, P<0.05). Conclusions:The adiponectin mRNA is decreased in the patients with gallstone of Hui/Han nationality in Qinghai Province. The low level of subcutaneous adiponectin and omental adiponectin are the risk factors for gallstone in obese or non obese people of Hui/Han nationality in Qinghai Province.

ABSTRACT

Objective:To investigate the roles and underlying mechanisms of mixed lineage kinase domain like (MLKL)-mediated inflammatory response induced by NOD-like receptor protein 3 (NLRP3) inflammatory corpuscles in the acute lung injury (ALI) after sepsis.Methods:Eighteen BALB/c mice were randomly divided into sham operation group (Sham group), cecal ligation and perforation (CLP)-induced sepsis model group (CLP group) and specific inhibitor Necrostatin-1 intervention group [CLP+Nec-1 group, Necrostatin-1 solution (20 mg/kg) was injected intravenously 10 minutes before modeling], with 6 mice in each group. The mice were sacrificed by neck amputation at the 2nd day after operation, and the serum and lung tissue samples were collected. The morphological changes of lung tissue were observed by hematoxylin-eosin (HE) staining. The water content of lung tissue was detected by dry-wet weight method. The pulmonary vascular permeability was measured by Evans blue (EB) staining. The protein expressions of MLKL and NLRP3 in the lung tissue were detected by Western blotting, and the level of serum interleukin-1β (IL-1β) was detected by enzyme linked immunosorbent assay (ELISA).Results:HE staining showed that the lung morphological structure in Sham group was normal. In CLP group, congestion and edema in the alveolar cavity and interstitium, infiltration of neutrophils and thickening of alveolar wall were observed. The histopathological changes of lung tissue in CLP+Nec-1 group were better than those in CLP group. Compared with Sham group, the water content of lung tissue [(88.00±0.00)% vs. (78.00±0.01)%], pulmonary vascular permeability [EB content (mg/L): 11.82±1.15 vs. 4.00±0.71], the protein expressions of phosphorylated MLKL (p-MLKL) and NLRP3 in lung tissue (p-MLKL/GAPDH: 0.34±0.04 vs. 0.12±0.01, NLRP3/GAPDH: 0.47±0.07 vs. 0.16±0.04), and the level of serum IL-1β (ng/L: 183.56±9.61 vs. 44.14±6.95) in CLP group were all significantly increased (all P < 0.01). Compared with CLP group, the water content of lung tissue [(81.00±0.01)% vs. (88.00±0.00)%], pulmonary vascular permeability [EB content (mg/L): 7.90±0.00 vs. 11.82±1.15], protein expressions of p-MLKL and NLRP3 in lung tissue (p-MLKL/GAPDH: 0.13±0.03 vs. 0.34±0.04, NLRP3/GAPDH: 0.18±0.04 vs. 0.47±0.07), and the level of serum IL-1β (ng/L: 113.81±6.62 vs. 183.56±9.61) were all significantly decreased (all P < 0.01). Conclusion:MLKL-NLRP3-mediated necroinflammation was significantly up-regulatedin the lung tissue of septic mice, which could be attenuated by specific inhibitor Necrostatin-1.

ABSTRACT

Objective:To compare the effect of SMOF lipids composed of soybean oil, medium chain triglycerides, olive oil, and fish oil with medium-long chain mixed fat emulsions(Lipofundin) on parenteral nutrition-associated cholestasis(PNAC) in premature infants.Methods:Clinical data were collected from premature infants hospitalized in the neonatal intensive care unit of Shanghai Children′s Hospital from January 2018 to December 2019 with gestational age ≤34 weeks, birth weight ≤2 000 g, and duration of parenteral nutrition ≥14 days.They were devided into SMOF lipid group and Lipofundin group, and the incidence of PNAC, neonatal necrotizing enterocolitis(NEC), bronchopulmonary dysplasia(BPD), retinopathy of prematurity(ROP), periventricular-intraventricular hemorrhage(PVH-IVH), late-onset sepsis and liver function were compared between two groups.Results:The incidence of PNAC in the SMOF lipid group was significantly lower than that in Lipofundin group( P=0.042). The average level of ALT and AST in SMOF lipid group were markedly lower than those in Lipofundin group( P<0.05). The time to reach full enteral feeding of SMOF lipid group was shorter than that of Lipofundin group( P=0.005). There was no significant difference in the incidence of NEC, BPD, ROP, PVH-IVH, and late-onset sepsis between two groups( P>0.05). Conclusion:Compared with lipofundin, SMOF lipid can reduce the incidence of PNAC in premature infants, and has no significant effect on the incidence of NEC, BPD, ROP, PVH-IVH and late-onset sepsis.

ABSTRACT

Objective:To study the effect of Jieyu Qutan Huazhuo prescription(JQHP) on the gut microbiota of rats with high-fat diet,and to explore the effect of Chinese medicine on the regulation of gut microflora and the restoration of gut-liver axis balance. Method:Seventy male SPF Wistar rats were randomly divided into a normal group of 10 and a model group of 60. Mice in the normal group were fed with normal diet and mice in the model group were fed high-fat diet. After 12 weeks,the model group was randomly divided into 6 groups with 10 animals in each group,namely the model group,Xuezhikang group,Liputuo group,and low,medium and high-dose groups of JQHP. The JQHP low-dose,medium-dose and high-dose rats were intragastrically daministered with 0.4,0.8,1.6 g·kg<sup>-1</sup>,respectively, rats in Liputuo group with Liputuo 2 mg·kg<sup>-1</sup>,rats in Xuezhikang group with Xuezhikang 0.1 g·kg<sup>-1</sup>. The rats in the normal group and the model group were intragastrically administered with the same amount of distilled water. Stool were collected after continuous gavaging for 8 weeks,16S rRNA gene sequencing was performed,blood was collected from the abdominal aorta to detect blood lipids,and the liver tissue and ileum tissue were collected for hematoxylin and eosin (HE) staining for pathomorphological observation. Result:Compared with the normal group,the total cholesterol (TC),triglyceride (TG),and low-density lipoprotein (LDL-C) in the model group were significantly increased,while the high-density lipoprotein (HDL-C) was decreased (<italic>P</italic><0.01). Compared with the model group,TC and TG values were decreased significantly in Xuezhikang group (<italic>P</italic><0.01),HDL-C value was increased (<italic>P</italic><0.05),and in the Liputuo group TC and TG were decreased significantly (<italic>P</italic><0.01). Compared with the model group,the middle-dose group of JQHP had a certain alleviating effect on liver steatosis and could reduce the infiltration of inflammatory cells. The JQHP could improve the proliferation of lymphoid tissues in the ileal structure,and the middle-dose group has the most significant effect. The results of Shannon curve showed that compared with the normal group,the middle-dose group of JQHP increased significantly (<italic>P</italic><0.01). Compared with the model group,the middle and high-dose group of JQHP increased (<italic>P</italic><0.05,<italic>P</italic><0.01). Compared with the middle-dose group of JQHP,the other drug group decreased (<italic>P</italic><0.05,<italic>P</italic><0.01). Principal component diversity analysis(PCA) showed that the diversity and abundance in the middle-dose JQHP group were higher than those in other drug groups. In linear discriminant analysis(LDA),compared with the normal group,Bacteroidia,Ruminococcaceae,<italic>Bacteroides </italic>S24-7,and <italic>Rumenococcus </italic>UCG-005 were down-regulated in the model group(<italic>P</italic><0.01),while the orders of Desulfovibrionales,Erysipelotrichales and<italic> </italic>Lachnospiraceae were up-regulated in the model group (<italic>P</italic><0.05,<italic>P</italic><0.01). Compared with the model group,the Bacteroidia,Ruminococcaceae,<italic>Bacteroides</italic> S24-7,and <italic>Rumencoccus</italic> UCG-005 in the middle-dose JQHP group were increased (<italic>P</italic><0.05,<italic>P</italic><0.01),and the orders of Erysipelotrichales were decreased (<italic>P</italic><0.01). Compared with the middle-dose JQHP group,Bacteroidia,Ruminococcaceae,<italic>Bacteroides</italic> S24-7,and <italic>Rumencoccus</italic> UCG-005 in other drug groups were reduced(<italic>P</italic><0.05,<italic>P</italic><0.01),and the order of Erysipelotrichales and Lachnospiraceae were increased (<italic>P</italic><0.05,<italic>P</italic><0.01). Conclusion:JQHP can regulate the abundance and diversity of the gut microbiota,improve the state of liver tissue and ileum mucosa,regulate blood lipid levels,and restore the normal intestinal ecological environment. It may be related to the regulation of inflammation-related gut microbiota in order to restore the balance of the gut-liver axis,and the middle-dose JQHP group has the best effect.

ABSTRACT

Objective:To solve the issue regarding a low correlation between visual and haptic feedback provided by the current upper-limb rehabilitation training system, this study was implemented based on the end-effector based upper-limb rehabilitation robot developed in the lab. A novel visual and haptic feedback fusion technology based on force tracking was investigated and its effect on upper-limb training was also studied. Methods:Based on the force model constructed in a virtual environment, two types of haptic feedbacks correlated to the visual feedback were designed, including the repulsive force when two objects getting close and the friction force when the object moving above medium surfaces. The haptic feedback constructed in the virtual environment was delivered to the trainees by using force tracking based on robot controlling algorithm. Eight health subjects were recruited and trained with and without feedback fusion. In the training process, the actual and expected haptic feedbacks as well as the surface electromyography (EMG) signals from anterior deltoid, posterior deltoid, biceps, and triceps were collected. The root means square error (RMSE) between the actual and expected haptic feedback was calculated under the feedback fusion training mode to characterize the force tracking-based multi-sensory feedback fusion technology. The integrated EMG values (iEMG) and EMG amplitudes per unit time (EMG/T) under two training modes were measured to explore the effect of feedback fusion technology on the upper-limb motor training. Results:Under feedback fusion training mode, the RMSE between actual and expected haptic feedback was (0.757±0.171) N. The values of iEMG from four muscles were significantly higher (|t| > 7.965, P < 0.001), and the values of EMG/T from the biceps, triceps and anterior deltoid were significantly larger under feedback fusion training mode than under the training mode without feedback fusion. Conclusion:The proposed upper-limb rehabilitation robot training system could accurately transmit the haptic feedback constructed under the virtual environment to the trainees. This system could increase the stimulation to trainees' peripheral nervous function through visual and haptic feedback fusion as well as increase the trainees' training effort. The advantages of force tracking-based visual and haptic feedback fusion technology are to freely construct the force model under the virtual environment and the haptic feedback mode is not constrained by the spatial position. Moreover, two or more types of force models can be superimposed in the same spatial position by using this technology that could improve the matching effect between haptic feedback and visual feedback under a virtual environment. The trainees' motor rehabilitation interest could be stimulated and the experience feeling of human-robot interaction could also be enhanced.

ABSTRACT

Objective:To construct a testing system for the effects of plantar surface vibration stimulation on the human postural adjustments, and to explore its practicability. Methods:The mechanical device and control system providing vibration stimulation were designed and built. Twenty-five healthy teachers and students (aged 19~29 years) were recruited from our college to participate in the experimental study from 2nd to 6th, October, 2019. The amplitudes of postural response were compared following non-stimulation and stimulation at left forefoot, left heel, right forefoot, right heel, left foot, right foot, double forefoot, double heels of each subject at the 20 Hz, 40 Hz, 60 Hz and 80 Hz vibrations, respectively. Results:The amplitude of the center of pressure response under foot cutaneous stimulation increased compared with the response amplitude under non-vibration conditions (P < 0.05). Conclusion:The locations of vibration as well as different vibration parameters (such as frequency, amplitude) could be adjusted, and the information of postural response to vibratory stimulation of the plantar surface, especially the excursion of center of pressure could be collected in the system which can be applied in the experimental study on the human posture control.

ABSTRACT

BACKGROUND@#We previously found that atorvastatin (ATV) enhanced mesenchymal stem cells (MSCs) migration, by a yet unknown mechanism. CXC chemokine receptor 4 (CXCR4) is critical to cell migration and regulated by microRNA-146a (miR-146a). Therefore, this study aimed to assess whether ATV ameliorates MSCs migration through miR-146a/CXCR4 signaling. @*METHODS@#Expression of CXCR4 was evaluated by flow cytometry. Expression of miR-146a was examined by reverse transcription-quantitative polymerase chain reaction. A transwell system was used to assess the migration ability of MSCs. Recruitment of systematically delivered MSCs to the infarcted heart was evaluated in Sprague–Dawley rats with acute myocardial infarction (AMI). Mimics of miR-146a were used in vitro, and miR-146a overexpression lentivirus was used in vivo, to assess the role of miR-146a in the migration ability of MSCs. @*RESULTS@#The results showed that ATV pretreatment in vitro upregulated CXCR4 and induced MSCs migration. In addition, flow cytometry demonstrated that miR-146a mimics suppressed CXCR4, and ATV pretreatment no longer ameliorated MSCs migration because of decreased CXCR4. In the AMI model, miR-146a-overexpressing MSCs increased infarct size and fibrosis. @*CONCLUSION@#The miR-146a/CXCR4 signaling pathway contributes to MSCs migration and homing induced by ATV pretreatment. miR-146a may be a novel therapeutic target for stimulating MSCs migration to the ischemic tissue for improved repair.

ABSTRACT

Compounds that selectively modulate multiple targets can provide clinical benefits and are an alternative to traditional highly selective agents for unique targets. High-throughput screening (HTS) for multitarget-directed ligands (MTDLs) using approved drugs, and fragment-based drug design has become a regular strategy to achieve an ideal multitarget combination. However, the unexpected presence of pan-assay interference compounds (PAINS) suspects in the development of MTDLs frequently results in nonspecific interactions or other undesirable effects leading to artefacts or false-positive data of biological assays. Publicly available filters can help to identify PAINS suspects; however, these filters cannot comprehensively conclude whether these suspects are "bad" or innocent. Additionally, these

ABSTRACT

OBJECTIVE@#To explore the effects of Eriodictyol to the growth, apoptosis and oxidative stress of Burkitt lymphoma (BL) cells and phosphorylation of protein kinase B (AKT) in children.@*METHODS@#The effects of Eriodictyol (0, 1.25, 2.5, 5, 10, 20, 40, 80, 160, 320 μmol/L) to viability of BL cell line DG-75 cells were detected by CCK-8. The effects of Eriodictyol (0, 10, 20, 40 μmol/L) to the proliferation activity of DG-75, apoptosis rate, levels of apoptosis-related proteins, oxidative stress indexes [superoxide dismutase (SOD), malondialdehyde (MDA)], mitochondrial membrane potential (MMP) and phosphorylation level of phosphatidylinositol-3-kinase (PI3K)/AKT/mammalian target of rapamycinm (mTOR) were detected by clony formation assay and Wester blot.@*RESULTS@#When the treatment concentration of Eriodictyol was 20 μmol/L, the proliferation activity of the cells was decreased (P<0.05). The concentrations at 10, 20, 40 μmol/L were selected for subsequent experiments. Compared with 0 μmol/L Eriodictyol, the proliferation activity of DG-75, SOD activity, MMP, phosphorylation levels of PI3K, AKT and mTOR in 20 and 40 μmol/L Eriodictyol treatment groups were significantly decreased (P<0.05), while cells apoptosis rate, Cleaved-Caspase-3/Caspase-3, Bax/Bcl-2 and MDA level were significantly increased (P<0.05).@*CONCLUSION@#Eriodictyol may promote the mitochondrial apoptosis pathway by inhibiting the abnormal activation of PI3K/AKT/mTOR to reduce the proliferation activity of DG-75, and inhibit oxidative stress response to increase the apoptosis rate and play anti-tumor roles.

ABSTRACT

With the development of precision medicine, therapies of targeting driver genes have significantly prolonged survival in advanced non-small cell lung cancer (NSCLC) patients. Among them, BRAF gene mutation is relatively rare, and the traditional regimen follows the treatment plan of NSCLC without driver gene mutation, which is far from meeting the clinical needs. In recent years, targeted therapy for NSCLC patients with BRAF V600E mutations has shown good efficacy when we are still exploring the better targeted therapies for other BRAF-mutated subtypes. Immunotherapy also showed positive antitumor activity in V600E and non-V600E subtypes of BRAF-mutated NSCLC. This article reviewed the progress of immunological and targeted therapy for patients with BRAF-mutated NSCLC.
