ABSTRACT

Objective:To explore the feasibility of applying quantitative flow ratio(QFR) to assess the degree of coronary artery functional stenosis before surgery, and to guide coronary artery bypass grafting(CABG) revascularization strategy.Methods:The study prospectively included a total of 154 patients who were electively treated with CABG in the 11th ward of the Department of Cardiac Surgery of Beijing Anzhen Hospital from January 2019 to September 2020, and their coronary angiography visually showed stenosis of the coronary artery to perform QFR analysis to know the diseased blood vessels. For functional stenosis, the surgeon was blinded to the results of QFR analysis before surgery. Collect its baseline data, perioperative data and recent clinical outcomes for summary analysis.Results:One year later, the coronary artery CTA showed that the occlusion rate of functionally significant disease(QFR<0.8) was 5.5%, and that of non-functionally significant disease(QFR≥0.8) was 15.6%. There was no difference in angina class or repeat interventions between patients with or without occluded bypass grafts.Conclusion:According to QFR analysis, coronary arteries with functional non-significant disease have a higher risk of grafts failure than those with functionally significant disease. For coronary arteries with negative QFR lesions, the risk of occlusion of arterial grafts is higher than that of venous. However, this finding is not significantly related to clinical prognosis, because patients with patency or occlusion of the grafts in non-significant lesions have not found excessive angina pectoris or repeated coronary interventions. QFR-guided selection of coronary surgery strategies is safe and feasible.

ABSTRACT

ObjectiveWe aimed to investigate the efficacy and mechanism of Yishen Shengjing Prescription (YSP) in the treatment of oligoasthenospermia in rats. MethodThe oligoasthenospermia rat model was established by injection with cyclophosphamide (35 mg·kg-1·d-1) for 5 consecutive days. Rats were randomly assigned into control group (without treating with cyclophosphamide), model group, low- (YSP-L), medium- (YSP-M), and high- (YSP-H) dose (2.91, 5.83, and 11.66 g·kg-1, respectively) groups, Wuzi Yanzongwan (WYW, 1.03 g·kg-1) group, and L-carnitine (0.17 g·kg-1) group, with 8 rats in each group. After 28 days of drug intervention, the body weight, testicular weight, and testicular index of rats were recorded. The sperm quality in epididymis was detected by computer-assisted sperm analysis (CASA) system. Hematoxylin-eosin (HE) staining was employed for observation of testicular tissue morphology. The levels of malondialdehyde (MDA) and superoxide dismutase (SOD) in testicular tissue were detected by colorimetry. The levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (T) in serum were determined by enzyme-linked immunosorbent assay(ELISA). TdT-mediated dUTP nick-end labeling (TUNEL) was employed to detect the apoptosis of testicular cells. The protein levels of B cell lymphoma-2(Bcl-2), Bax, and cleaved Caspase-3 in testicular tissue were detected by Western blot. ResultCompared with the control group, the model group showed decreased body weight, testicular weight and index, sperm concentration and motility (P<0.01) and increased testicular pathological score (P<0.01). Compared with the model group, the YSP-M, YSP-H, WYW, and L-carnitine groups showed increased body weight, testicular weight, testicular index, sperm concentration and motility and decreased testicular pathological score. After modeling, the SOD level decreased (P<0.01) while the MDA content increased (P<0.01) in the testicular tissue. YSP-H, WYW, and L-carnitine reversed the SOD and MDA level changes caused by modeling. Compared with the control group, the model group exhibited declined T level (P<0.01) and increased FSH and LH levels (P<0.01). Compared with the model group, YSP, WYW, and L-carnitine increased the T level (P<0.01) and decreased the LH level (P<0.05, P<0.01). The apoptosis rate of spermatogenic cells in the model group was higher than that in the control group (P<0.01), whereas YSP-M, WYW, and L-carnitine reversed such changes (P<0.01). The model group rats showed decreased expression of Bcl-2(P<0.05) and increased expression of Bax and cleaved Caspase-3 (P<0.05, P<0.01). Compared the model group, YSP-M, YSP-H, WYW, and L-carnitine up-regulated the Bcl-2 expression and down-regulated the cleaved Caspase-3 expression (P<0.05, P<0.01). ConclusionYSP improved the sperm quality of oligoasthenospermia model rats by regulating the antioxidant system and sex hormone levels and inhibiting the apoptosis of spermatogenic cells.

ABSTRACT

ObjectiveTo investigate the effect of Biejiajian Wan (BJJW) on transforming growth factor-β1 (TGF-β1)-induced epithelial-mesenchymal transition (EMT) of HepG2 cells, and explore its mechanism against EMT of hepatocellular carcinoma cells. MethodHepG2 cells were randomly divided into a blank group, a TGF-β1 model group (10 μg·L-1 TGF-β1), a low-dose BJJW group (10 μg·L-1 TGF-β1+0.55 g·kg-1 BJJW), a medium-dose BJJW group (10 μg·L-1 TGF-β1+1.1 g·kg-1 BJJW), a high-dose BJJW group (10 μg·L-1 TGF-β1+2.2 g·kg-1 BJJW), and a sorafenib group (10 μg·L-1 TGF-β1+0.03 g·kg-1 sorafenib). The EMT model was induced by 10 μg·L-1 TGF-β1 in HepG2 cells. After treatment with corresponding medicated serum, cell counting kit -8 (CCK-8) assay was used to detect cell proliferation. Cell migration ability was detected by the Transwell assay and wound healing assay. The protein expression related to EMT and nuclear factor-kappa B (NF-κB) signaling pathway was detected by cell immunofluorescence assay and Western blot. ResultCompared with the blank group 4 days later, the TGF-β1 model group showed fusiform and loose cells with widened gap and antennae reaching out, decreased protein expression of E-cadherin (P<0.05), and increased protein expression of N-cadherin and vimentin (P<0.05), which indicated that the EMT model was properly induced in HepG2 cells by TGF-β1 stimulation for 4 days. After 48 hours of treatment with the corresponding medicated serum, each medication group showed inhibited proliferation of HepG2 cells that had undergone EMT, especially the low- and high-dose BJJW groups (P<0.01), and the medium-dose BJJW group showed increased E-cadherin protein expression (P<0.05) and decreased p-p65, N-cadherin, and vimentin protein expression (P<0.05), as compared with the TGF-β1 model group. As revealed by the transwell assay and wound healing assay, TGF-β1 enhanced the migration ability of HepG2 cells (P<0.05, P<0.01) compared with the results in the blank group, compared with the TGF-β1 model group, the medication groups showed inhibited migration ability of HepG2 cells (P<0.05, P<0.01). Compared with the blank group, the TGF-β1 model group promoted the expression of p65 and Snail into the nucleus. Compared with the TGF-β1 model group, the medication groups inhibited the expression of p65 and Snail into the nucleus. ConclusionBJJW may inhibit the EMT, proliferation, and migration of HepG2 cells induced by TGF-β1 by suppressing the NF-κB signaling pathway to exert an anti-hepatocellular carcinoma effect.

ABSTRACT

Impaired immunomodulatory capacity and oxidative stress are the key factors limiting the effectiveness of mesenchymal stem cell transplantation therapy. The present study was aimed to investigate the effects of jujuboside A (JuA) on the protective effect and immunomodulatory capacity of human umbilical cord mesenchymal stem cells (hUC-MSCs). Hydrogen peroxide was used to establish an oxidative damage model of hUC-MSCs, while PBMCs isolated from rats were used to evaluate the effect of JuA pre-treatment on the immunomodulatory capacity of hUC-MSCs. Furthermore, Hoechst 33258 staining, lactate dehydrogenase test, measurement of malondialdehyde, Western blot, high-performance liquid chromatography; and flow cytometry were performed. Our results indicated that JuA (25 μmol·L-1) promoted the proliferation of hUC-MSCs, but did not affect the differentiating capability of these cells. JuA pre-treatment inhibited apoptosis, prevented oxidative damage, and up-regulated the protein expression of nuclear factor-erythroid factor 2-related factor 2 and heme oxygenase 1 in hUC-MSCs in which oxidative stress was induced with H2O2. In addition, JuA pre-treatment enhanced the inhibitory effect of hUC-MSCs against abnormally activated PBMCs, which was related to stimulation of the expression and activity of indoleamine 2,3-dioxygenase. In conclusion, our results demonstrate that JuA pre-treatment can enhance the survival and immunomodulatory ability through pathways related to oxidative stress, providing a new option for the improvement of hUC-MSCs in the clinical setting.

ABSTRACT

OBJECTIVE:To study the toxicity mechanism of yunacotine-induced arrhythmia in rats. METHODS :Totally 32 rats were randomly divided by random number table method into normal control group ,yunacotine low-dose and high-dose groups (0.09,0.14 mg/kg),aconitine group (positive control ,0.88 mg/kg),with 8 rats in each group. Administration groups were given the corresponding drugs once a day ,and normal control group was given the constant volume of normal saline ,for consecutive 7 d. After last intragastric administration ,the changes of electrocardiogram (ECG) were observed. The contents of adenosine triphosphate(ATP)in myocardial tissue and Ca 2+ in myocardial cells ,the activities of Na +-K+-ATPase and Ca 2+-Mg2+-ATPase as well as the protein expression of ranolidine receptor 2(RyR2)and Ca 2+-ATPase(SERCA2)in myocardial tissue were determined. RESULTS:Compared with normal control group ,time limit of QRS wave and QTc intervals of rats were prolonged significantly in yunaconitine low-dose group (P<0.01). The content of Ca 2 + in myocardial cells , the ATP contents , the activities of Ca2+-Mg2+-ATPase and Na +-K+-ATPase as well as the protein expression of SERCA 2 in myocardial tissue were reduced significantly (P<0.05 or P<0.01). The heart rate of rats in yunaconitine high-dose group and aconitine group were increased significantly (P< 0.05 or P<0.01),and time limit of QRS wave and QTc intervals were significantly prolonged (P<0.01);the content of Ca 2+ in myocardial cells was increased significantly (P<0.01);ATP content ,the activities of Ca 2+-Mg2+-ATPase and Na +-K+-ATPase,and protein expression of RyR 2 and SERCA 2 in myocardial tissue were decreased significantly (P<0.01). CONCLUSIONS : Yunaconitine can induce arrhythmia in rats ,the mechanism of which may be associated with Ca 2+ overload that resulted from reducing the activities of Na +-K+-ATPase and Ca 2+-Mg2+-ATPase and down-regulating the expression of related calcium transporter RyR2 and SERCA 2.

ABSTRACT

Objective:To investigate the action mechanism of Yinchenhao Tang against type 2 diabetes mellitus (T2DM) complicated with non-alcoholic fatty liver disease (NAFLD) in MKR mice. Method:Forty eight-week-old MKR mice were fed a high-fat diet for eight weeks and then divided into the model group,original Yinchenhao Tang (17.16 g·kg<sup>-1</sup>) group,Yinchenhao Tang group at a specified dose (4.68 g·kg<sup>-1</sup>) in teaching materials,and positive drug [metformin + simvastatin, (65+2.6)×10<sup>-3</sup> g·kg<sup>-1</sup>] group. Another 10 MKR mice of the same age were classified into the blank group and 10 FVB mice into the normal group. After eight weeks of intragastric administration in each group,the liver wet weight,oral glucose tolerance test (OGTT),serum inflammatory factors interleukin-6 (IL-6) and tumor necrosis factor-<italic>α</italic> (TNF-<italic>α</italic>),and changes in blood lipid and liver function were determined. Hematoxylin-eosin (HE) staining was conducted for observing the morphological changes in liver tissue under a transmission electron microscope,followed by the detection of Toll-like receptor 4 (TLR4),myeloid differentiation factor 88 (MyD88),and nuclear transcription factor-<italic>κ</italic>B (NF-<italic>κ</italic>B) protein expression by Western blot. Result:Compared with the model group,the medication groups exhibited significantly reduced liver wet weight index (<italic>P</italic><0.01),improved OGTT result (<italic>P</italic><0.05),and down-regulated serum IL-6 and TNF-<italic>α</italic> levels (<italic>P</italic><0.01). In terms of morphological changes,Yinchenhao Tang protected the hepatocyte structure and alleviated hepatocyte steatosis. Moreover, Yinchenhao Tang obviously down-regulated the protein expression levels of TLR4,MyD88,and NF-<italic>κ</italic>B in liver tissue of MKR mice with T2DM combined with NAFLD (<italic>P</italic><0.05),and the down-regulation of TLR4 and NF-<italic>κ</italic>B in the original Yinchenhao Tang group was better than that in the Yinchenhao Tang group at a specified dose in teaching materials (<italic>P</italic><0.05). Conclusion:Yinchenhao Tang is able to reduce inflammatory factor levels and down-regulate TLR4,MyD88,and NF-<italic>κ</italic>B expression in liver tissue to relieve the pathological liver injury and interfere with T2DM combined with NAFLD of MKR mice. It exerts a certain liver-protective effect by lowering the blood lipids and delaying the hepatic inflammation.

ABSTRACT

Objective:To study the effect of Biejiajian Wan on the epithelial-mesenchymal transition (EMT) of rat hepatic oval cells induced by transforming growth factor- β1(TGF-β1), in order to explore its mechanism in reversing EMT. Method:WB-F344 cells were divided into five groups: blank group, TGF-β1 model group (10 μg·L-1TGF-β1), low-dose group (10 μg·L-1TGF-β1+0.55 g·kg-1Biejiajian Wan), medium-dose group (10 μg·L-1TGF-β1+1.1 g·kg-1Biejiajian Wan), high-dose group (10 μg·L-1TGF-β1+2.2 g·kg-1Biejiajian Wan). Except blank group, TGF-β1 was used to induce WB-F344 cells in all of the remaining groups to construct an EMT model. After the cells were treated with low, medium and high doses of Biejiajian Wan serum, the changes of migration ability of WB-F344 cells were detected by cell scratching test. The expressions of E-cadherin, N-cadherin and Vimentin were detected by Western blot. Real-time PCR was used to detect the changes in the expression of β-catenin mRNA. The expression of β-catenin was detected by cell immunofluorescence assay. Result:Compared with normal WB-F344 cells, the intercellular space of WB-F344 cells became loose from tight, and the morphology changed from cobblestone to fibroblast after TGF-β1 induced WB-F344 cells for 4 days, and the expression of E-cadherin protein decreased, while the expression of N-cadherin protein increased (P<0.01), indicating that the EMT model of WB-F344 cells was successfully built. Compared with the blank group, the migration ability of WB-F344 cells in TGF-β1 model group was enhanced (P<0.01), compared with TGF-β1 model group, Biejiajian Wan could significantly inhibit the migration ability of WB-F344 cells; specifically, the low-dose group had no statistical significance, and the medium and high-dose groups had statistical significance (P<0.05). Western blot results showed that compared with the blank group, the expression of E-cadherin decreased, whereas those of N-cadherin and Vimentin increased in the TGF-β1 model group (P<0.01), compared with TGF-β1 model group, E-cadherin protein expression was increased in the low, medium and high-dose groups, while the expressions of N-cadherin and Vimentin was decreased; specifically, the low-dose groups had no statistical significance, and the medium and high dose groups had statistical significance (P<0.05,P<0.01). Real-time PCR results showed that compared with the blank group, the mRNA expression of β-catenin in the TGF-β1 model group was increased (P<0.05), whereas compared with TGF-β1 model group, the mRNA expression of β-catenin in the low, medium and high-dose groups of Biejiajian Wan was reduced (P<0.01). The results of cellular immunofluorescence showed that compared with the blank group, the fluorescence expression of β-catenin in the cell nucleus was enhanced in the TGF-β1 model group; and compared with the TGF-β1 model group, the expression of β -catenin in the cell nucleus of the low, medium and high-dose groups of Biejiajian Wan decreased, and the inhibitory effect of Biejiajian Wan on β-catenin in the cell nucleus was positively correlated with its concentration. Conclusion:Biejiajian Wan may reverse the EMT process that TGF-β1 induced WB-F344 cells, and inhibit the migration of WB-F344 cells by inhibiting Wnt/β-catenin signaling pathway.

ABSTRACT

Accurate assessment of the degree of coronary artery stenosis is very important to guide the revascularization of patients with coronary heart disease. In recent years, functional assessment of the impact of coronary artery stenosis on the distal myocardium is changing the traditional concept of revascularization. The superiority of the fractional flow reserve(FFR) in guiding coronary interventional therapy has been widely verified in clinical practice. Due to its invasive operation, high cost, and high side effects of vasodilators during examinations, its application in my country is relatively limited. Quantitative flow ratio as a new, noninvasive, and rapid tool for assessing coronary stenosis, is being favored by researchers. This article reviews the clinical research progress of quantitative flow ratio and prospects its future clinical applications.

ABSTRACT

OBJECTIVES@#To establish mouse bone marrow transplantation by pretreatment with chemotherapy, and to explore the dynamic changes of immune cells in the early stage of allogeneic transplantation in the spleen of mice.@*METHODS@#Mice were divided into 4 groups (80 mg/kg group, 100 mg/kg group, 120 mg/kg group, and 150 mg/kg group) according to the difference in dose of busulfan. The mice were treated with busulfan and cyclophosphamide combined chemotherapy, and the appropriate dosage was determined by evaluating the myeloablative effect and drug toxicity. According to the type of the genetic transplantation, the mice were also divided into 4 groups: An allogeneic transplantation group, a homogenic transplantation group, a chemotherapy alone group, and a normal control group. The mice were pretreated with busulfan and cyclophosphamide before bone marrow transplantation. In the allogeneic transplantation group, the suspension of splenocytes was prepared at the first day, the 3rd day, the 5th day, and the 8th day after transplantation for flow cytometry detection, and the dynamic changes of splenic immune cells were analyzed. The homogeneic transplantation group served as the concurrent control, the normal control group served as the control of basic value of spleen immune cells, and the chemotherapy alone group was used to evaluate the myeloablative effect.@*RESULTS@#1) The optimal dose of busulfan was 100 mg/kg. The combination of busulfan and cyclophosphamide can restore the hematopoiesis of transplanted mice, and the toxicity associated with pretreatment is small. 2) In the allogeneic transplantation group: The hematopoietic reconstitution and high donor chimerism rate were achieved after transplantation. In the early phase of bone marrow transplantation, the T lymphocytes were the main cell group, while the recovery of B lymphocytes was relatively delayed. The dendritic cells and natural killer cells from donors were the earliest cells to recover and achieve high chimerism rate compared with T cells and B cells. Most T cells were in the initial T cell state within 5 days after allogeneic transplantation. However, in the 5th day after transplantation, these cells were mainly in the effective memory phenotype. The reconstruction of donor-derived naive T cells was slow, but the reconstruction of donor-derived effective memory T cells and regulatory T cells was relatively fast. 3) In the homogeneic transplantation group: The mice could recover hematopoiesis and the recovery of B lymphocytes was delayed. 4) In the chemotherapy alone group: All mice died in 12-15 days after chemotherapy, and the peripheral blood routine showed pancytopenia before death.@*CONCLUSIONS@#Pretreatment with chemotherapy can successfully establish the mouse model of bone marrow transplantation. There are difference in the proportion of T cells, B cells, natural killer cells, dendritic cells, effector memory T cells, initial T cells, and regulatory T cells after transplantation, and the relationship between donor and recipient is also changed.

ABSTRACT

Chronic myeloid leukemia with a significant increase of monocytes is rare and difficult to identify from chronic myelo-monocytic leukemia in clinic. A 31-year-old male patient with systemic pain was initially diagnosed as chronic myelo-monocytic leukemia, who was finally diagnosed as chronic myeloid leukemia by fusion gene and chromosome examination. In addition to the typical Ph chromosome, a rare chromosome translocation t(2; 7)(p13; p22) was observed. The detection of monocyte subsets by multi-parameter flow cytometry is a diagnostic marker to distinguish the above 2 diseases. The relationship between fusion genes and mononucleosis is not clear. Tyrosine kinase inhibitors or allogeneic hematopoietic stem cell transplantation can be used in the treatment for this disease.

ABSTRACT

Objective To explore the recovery mechanism of language network among post-stroke aphasic patients by investigating the difference of whole-brain amplitude of low frequency fluctuations (ALFF) and the Granger causality analysis (GCA) between the patients and the controls. Methods From May, 2019 to May, 2021, 19 patients with aphasia after left hemispheric stroke and 17 age- and sex- matched healthy controls finished functional magnetic resonance imaging scanning. All the patients assessed with Chinese version of Western Aphasia Battery (WAB). Restplus was used for fMRI data analysis. Regions with significant difference of ALFF between groups were chosen as regions of interests (ROI) for the following GCA analysis. Results ALFF in left inferior frontal gyrus triangle (LIFGtri) and left medial frontal gyrus (LMFG) were significantly lower in the patients than in the controls. Effective connectivity from LIFGtri to LMFG and from LMFG to the right cerebellar Crus I were significantly lower in the patients. Effective connectivity from right cerebellar Crus II to LIFGtri, from right cerebellar Crus I to LMFG were significantly greater in the patients. Conclusion Unidirectional negative regulatory pathway such as LIFGtri→LMFG might be injured in post-stroke aphasia, while, connectivities between right cerebellar Crus II→LIFGtri and right cerebellar Crus I →LMFG enhanced. Right cerebellum might be the potential target for the language recovery.

ABSTRACT

Objective:To investigate the value of real-time shear wave elastography (SWE) in the diagnosis of acute testicular torsion.Methods:A total of 30 rabbits were randomly divided into 3 groups including control group (Group S), complete torsion group (Group C) and incomplete torsion group (Group U), and corresponding animal models were built. Rabbits in each group were examined by gray scale and color Doppler ultrasound, SWE and contrast-enhanced ultrasound(CEUS) before and after operation. Mean values of elasticity modulus (Emean) of testicular capsule area, parenehyma testis, spermatic cord torsion section, torsion lower section and contrast-enhanced ultrasound parameters were recorded and then pathological examinations were performed.Results:There was no significant difference for Emean values of each group in all parts before operation( P>0.05). There was no significant difference for Emean value of S group at each period after operation( P>0.05). Emean value of postoperative testicular capsule area in U group increased obviously and rapidly compared with C group, yellow or red "hard ring signs" appeared within four to six hours after operation, there was significant difference of Emean value difference at various periods after operation in group U and C, and at 1 h, 1.5 h, 2 h, 2.5 h, 3 h and 3.5 h postoperatively between group U and C( P<0.05). Postoperative Emean value of parenchyma testis in group C and U increased about 5 kPa, expression of SWE was consistent blue. Postoperative Emean value of spermatic cord torsion section in group C increased more obviously compared with U group, a large patch of red signals appeared within five to six hours after operation, there was significant difference of Emean value at various periods after operation in group C and U, and at each period except instant, 2 h, and 3 h postoperatively between group C and U( P<0.05). Postoperative Emean value in spermatic cord torsion lower section in group U and C increased slowly ( P<0.05), expression of SWE changed from blue to blue green and green from original blue. CEUS showed blood pefusion in testis was "in and out slowly " in group U, pathological feature showed the testicular spermatogenic cells were in disorder with interstitial edema, distinct expansion of microvascular lumen, hyperemia and congestion and lots of erythrocyte leakage. CEUS showed postoperative contrast agent was not filling in testicular in group C, pathological feature showed the testicular spermatogenic cells were in disorder with interstitial edema, slight expansion of microvascular lumen, congestion and part erythrocyte leakage. Conclusions:The image changes of SWE after acute testicular torsion are related with the degree and time of torsion, the changes of testicular capsule area and spermatic cord torsion section are most significant. The use of SWE helps to get accurate hardness information of focus with effective clinical value for the diagnosis testicular torsion.

ABSTRACT

Objective:To explore the different functional connectivity of right caudate nucleus between adults with high myopia and normal vision controls.Methods:The resting-state functional magnetic resonance imaging(fMRI) data were collected from twenty-five high myopia(HM group) and twenty-seven normal vision subjects(NC group). Right caudate nucleus and their subregions(anterior and posterior subregions included) were used as seeds to perform seed-based functional connectivity (FC)analyses at group level under three different frequency bands: convention (0.010~0.080 Hz), slow-5(0.010~0.027 Hz) and slow-4(0.027~0.073 Hz).Results:(1)Compared with NC group, FC of right caudate nucleus with left middle occipital gyrus(MNI: x=-48, y=-84, z=9), left fusiform gyrus(MNI: x=-30, y=-63, z=-12), and right middle frontal gyrus(MNI: x=39, y=12, z=39) were stronger in HM group(all P<0.05, Alphasim Corrected). (2)In HM group, these changed FC were mainly detected in the anterior subregion of right caudate nucleus.(3)The increased FC of right caudate nucleus and its anterior subregion with left middle occipital in HM group were mainly reflected in the frequency band of slow-4(all P<0.05, Alphasim Corrected). Conclusion:The right caudate nucleus in adults with high myopia may play compensatory roles in visual perception and visual attention by enhancing its functional connectivity with visual and visual attentional brain areas.

ABSTRACT

Objective@#To investigate the clinical characteristics, memory and neuroimaging features of nonlesional temporal lobe epilepsy (TLE-NL).@*Methods@#Forty-four patients with TLE-NL and 53 patients with unilateral temporal lobe epilepsy with hippocampal sclerosis (TLE-HS) were recruited from the Second Affiliated Hospital of Zhejiang University from September 1st 2012 to August 31st 2017. The clinical characteristics were systematically analyzed and compared between TLE-NL and TLE-HS. Twenty healthy volunteers were also recruited. Memory assessment and high resolution magnetic resonance imaging (MRI) scanning were completed in the patients and healthy volunteers. Volume and shape of the hippocampus were compared between patients and healthy volunteers.@*Results@#Compared with the TLE-HS, TLE-NL patients showed later seizure onset ((24.3±12.6) vs (15.8±10.3) years; t=3.684, P<0.01), shorter duration of epilepsy ((4.00 (2.00, 8.75)) vs (14.00 (7.50, 22.00)) years; Z=-4.675, P<0.01), less history of febrile convulsions (4.5% (2/44) vs 62.3% (33/53); χ2=32.270, P<0.01) and lower incidence of pharmacoresistant epilepsy (47.7% (21/44) vs 84.9% (45/53); χ2=15.282, P<0.01). However, there were no statistically significant differences between TLE-NL and TLE-HS in sex ratio, family history of epilepsy, lateralization of the epileptogenic zone, presence of aura, seizure types and seizure frequency. TLE-NL patients had normal memory quotient compared to normal controls (105.2±17.4 vs 103.8±16.2; P=1.000), while TLE-HS patients had significant memory impairment compared to normal controls (84.5±20.3 vs 103.8±16.2; P<0.01). Compared to normal controls, TLE-NL patients did not have significant alteration in hippocampal volume and shape, while TLE-HS patients had significant atrophy in the ipsilateral hippocampus ((2 953±481) mm3 vs (4 431±505) mm3; P<0.01), and shape analysis showed significant atrophy in the head and body of the hippocampus.@*Conclusion@#TLE-NL has different characteristics compared with TLE-HS, including later seizure onset, shorter duration of epilepsy, less history of febrile convulsions, better response to antiepileptic drugs, and no significant memory impairment and hippocampal atrophy.

ABSTRACT

OBJECTIVE@#To investigate the understanding of speech sound disorder (SSD) among child health practitioners.@*METHODS@#The clinical data of 506 children with an initial diagnosis of SSD from January 2017 to May 2019 were retrospectively analyzed.@*RESULTS@#Of the 506 SSD children, 90.5% had a description of developmental behavior in their medical records; 97.6% received a developmental-behavioral evaluation, mostly intellectual and developmental screening tests, which were given to 95.8% (485/506) of the total children. A total of 116 (22.9%) children also had neurodevelopmental disorders, commonly presenting with language disorder, global developmental delay, and intellectual disability; however, 53 (45.7%) of the 116 children had no history records of such abnormal developmental behavior. The incidence of neurodevelopmental disorders was significantly higher in the children with abnormal hearing reported by their families than in the children with normal hearing reported by their families (P<0.001). The children with abnormal response to sound stimulation on physical examination had significantly more frequent neurodevelopmental disorders than those with normal response to sound stimulation (P<0.05). Among the 506 children with SSD, hearing condition was ignored in 33.2% in history records, and in 31.2% on physical examination. Ninety-two children (18.2%) completed the diagnostic hearing test, 12% (11/92) of whom were diagnosed with hearing loss. Of the 11 children with hearing loss, three had passed a hearing screening, three had family-reported normal hearing, and seven had normal response to sound stimulation on physical examination.@*CONCLUSIONS@#SSD is frequently comorbid with neurodevelopmental disorders in children. Children's communication performance is a key to the diagnosis of neurodevelop-mental disorders. It's necessary to the diagnosis of SSD to perform a medical history collection about neuropsychological development and a developmental-behavior evaluation. There is a high proportion of children with SSD receiving the developmental-behavioral evaluation, suggesting that child health practitioners pay close attention to the neuropsychological development of SSD children, but mostly, the evaluation merely involves intellectual developmental screening tests. The detection rate of hearing loss in children with SSD is high. However, child health practitioners underestimate this problem, and have an insufficient understanding of the importance of the diagnostic hearing test. The diagnostic hearing test should be the preferred recommendation for assessing hearing ability rather than past hearing screening results or children's response to sound stimulation in life scenes.

ABSTRACT

This study analyzed the effect of the Radix Bupleuri-Radix Paeoniae Alba herb pair on endogenous metabolites in rats with chronic unpredictable mild stress (CUMS)-induced depression by using LC-MS liver metabolomics. Rats were randomly divided into 5 groups: a normal control group, a CUMS model group, a venlafaxine-positive group, and a high-low dose group for the Radix Bupleuri-Radix Paeoniae Alba herb pair, with continuous modeling and administration over 28 days. The efficacy of Radix Bupleuri-Radix Paeoniae Alba herb pair was evaluated by measuring traditional pharmacodynamic indicators of depression (body weight, open field test, sucrose preference test and forced swimming test). Animal experimentation was approved by the Committee on the Ethics of Animal Experiments of Shanxi University (SXULL2016036). Liver metabolic profiles were obtained by the UHPLC-Q Exactive Orbitrap-MS metabolomics technique. The results show that the Radix Bupleuri-Radix Paeoniae Alba herb pair can significantly decrease depression-like behavior of rats in the CUMS model group. Increases in 25 depression-related metabolites were identified by LC-MS metabonomics, and the Radix Bupleuri-Radix Paeoniae Alba herb pair could significantly decrease 16 of them. Metabolic pathway analysis showed that D-glutamine and D-glutamate metabolism, arginine and proline metabolism, alanine, aspartate and glutamate metabolism, and glutathione metabolism were the main metabolic pathways altered by this herb pair in CUMS model rats.

ABSTRACT

Objective:To study the effect of Biejia Jianwan on expressions of signal molecules and target genes of transforming growth factor-β (TGF-β)/Smad pathway in diethylnitrosamine (DEN)-induced rat hepatocellular carcinoma, and explore the mechanisms of Biejia Jianwan suppressing the invasion of hepatocellular carcinoma. Method:The rats were divided into three group, namely normal group, model group and Biejia Jianwan group (2.2 g·kg-1·d-1). Rats in Biejia Jianwan group and model group received intraperitoneal injections of DEN to induce sequential chronic inflammation, cirrhosis and hepatocellular carcinoma. At the sign of cirrhosis, rats in Biejia Jianwan group began taking Biejia Jianwan by gavage for 6 weeks. Rat blood was collected to measure serum levels of biochemical markers of liver function tests, including alanine aminotransferase(ALT), aspartate aminotransferase(AST), total bilirubin(TBIL), albumin(Alb), γ-glutamyl transpeptadase(GGT), alkaline phosphatase(ALP). Rat livers were fixed in formalin and stained with hematoxylin-eosin (HE)staining, quantitative real-time PCR was used to test the mRNA expressions of TGF-β1, and Western blot was used to test protein expressions of TGF-β1, Smad2/3, p-Smad2/3, N-cadherin, E-cadherin and Vimentin. Result:All of the levels of biochemical markers showed no difference in Biejia Jianwan group and model group. Biejia Jianwan could improve the pathological changes of balloon-like degeneration, edema, and necrosis in liver cancer tissues. Importantly, the treatment dramatically decreased the mRNA expression of TGF-β1(P<0.01), and the protein expressions of TGF-β1, p-Smad2(P<0.01). Besides, the protein expression of N-cadherin and Vimentin were decreased significantly (P<0.01). Conclusion:Biejia Jianwan can inhibit epithelial-mesenchymal transition (EMT) in hepatocellular carcinoma cells activated via TGF-β/Smad pathway by reducing TGF-β1 expression, so as to suppress the metastasis and invasion of hepatocellular carcinoma.
