ABSTRACT
The purpose of this study was to explore the improving effect of Anshen Dingzhi Prescription (ADP) on Alzheimer's disease (AD)-like behavior in mice and its mechanisms. The main chemical components of ADP were identified by ultra performance liquid chromatography-time-of-flight mass spectrometry (UPLC-Q-TOF-MS). The AD-like mouse model was induced by D-galactose (D-gal) combined with Aβ1-42 oligomer (AβO). The effect of ADP on AD-like behavior in mice was assessed using various behavioral experiments; pathomorphological changes in mouse hippocampal tissue were observed by Nissl staining and transmission electron microscopy; ELISA was used in the assessment of oxidative stress factors and inflammation-related factor levels; Western blot was performed to detect the expression of Aβ, Tau and glial fibrillary acidic protein (GFAP) proteins. The active components of ADP were screened according to TCMSP and HERB database, and the action targets of active components were predicted by Swiss Target Prediction platform. In addition, the targets of AD were predicted through DisGeNET database. Further, GO and KEGG enrichment analysis of common targets was carried out by Metascape database. Combined with the results of GO and KEGG analysis, in vivo experiments were carried out to explore the potential mechanism of ADP improving AD-like behavior in mice from the PI3K/Akt, calcium signal pathway and synaptic function. Finally, the core components of ADP were molecularly docked to the validated targets using Autodock Vina. Animal experiments were approved by the Animal Ethics Committee of Anhui University of Chinese Medicine (approval number: AHUCM-mouse-2021080). The results showed that the five chemical components, including ginsenoside Rg1, ginsenoside Rb1, tenuifolin, poricoic acid B and α-asarone were found in the ADP. ADP significantly improved the anxiety-like behavior and memory impairment, protected hippocampal neurons, decreased the levels of oxidative stress and inflammation, and inhibited the expression of Aβ and p-Tau induced by D-galactose combined with AβO in mice. The results of network pharmacology suggested that PI3K/Akt, calcium signal pathway and cell components related to postsynaptic membrane might be the key factors for ADP to improve AD. Animal experiments revealed that ADP up-regulated N-methyl-D-aspartate receptor 2A (GluN2A), postsynaptic density protein 95 (PSD95), calpain-1, phosphorylated protein kinase B (p-Akt), phosphorylated cAMP response element binding protein (p-CREB), brain-derived neurotrophic factor (BDNF) expression and inhibited p-GluN2B and calpain-2 expression in the hippocampus of AD-like mice. The molecular docking results demonstrated that the core components of ADP, such as panaxacol, dehydroeburicoic acid, deoxyharringtonine, etc. had a high binding ability with the validated targets GRIN2A, GRIN2B, PSD95, etc. In summary, our results indicate ADP improves AD-like pathological and behavioral changes induced by D-galactose combined with AβO in mice, and the mechanism might be related to the NMDAR/calpain axis and Akt/CREB/BDNF pathway.
ABSTRACT
Objective: To analyze the pathological classification of malignant peritoneal mesothelioma (MPeM) and screen the immunohistochemical markers that can distinguish MPeM from peritoneal metastatic carcinoma (PC) . Methods: In June 2020, the pathological results of peritoneal biopsy of 158 MPeM and 138 PC patients from Cangzhou Central Hospital, Cangzhou People's Hospital, and Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine from May 2011 to July 2019 were retrospectively analyzed, and the pathological classifications of MPeM in Cangzhou were summarized. Immunohistochemical markers of MPeM and PC patients were analyzed, and receiver operating characteristic curve (ROC curve) was drawn for differential diagnosis of MPeM and PC. Results: There were 55 male and 103 female MPeM patients in Cangzhou, with an average age of 57.1 years old. The asbestos exposure rate was 91.14% (144/158). The most common pathological classifications were cutaneous type, accounting for 90.51% (143/158). There were significant differences in the expression of calreticulum protein, CK5/6, vimentin, D2-40, carcinoembryonic antigen (CEA) and tail type homologous nuclear gene transcription factor 2 (CDX-2) between MPeM and PC (P<0.05). Among the 6 positive markers, the sensitivity of calreticulum protein was the highest (0.905) and CEA was the lowest (0.428) . Conclusion: Calreticulum protein, CK5/6, vimentin, D2-40, CEA and CDX-2 may be used as specific markers to distinguish the diagnosis of MPeM from PC.

BACKGROUND@#Available research about the anatomic patterns of intertrochanteric fractures is lacking, and fracture mapping has not previously been performed on intertrochanteric fractures. This study aimed to determine the major trajectories of intertrochanteric fracture lines using computed tomography data from a series of surgically treated patients.@*METHODS@#In this study, 504 patients with intertrochanteric fractures were retrospectively analyzed. Fracture patterns were graded according to Arbeitsgemeinschaft für Osteosynthesefragen (AO) classification. Fracture lines were transcribed onto proximal femoral templates and graphically superimposed to create a compilation of fracture maps that were subsequently divided into anterior, posterior, lateral, and medial fracture maps to create a three-dimensional (3D) pattern by reducing fragments in the 3D models. The fracture maps were then converted into frequency spectra. The major fracture patterns were assessed by focusing on the lateral femoral wall, lesser trochanter, intertrochanteric crest, and inner cortical buttress.@*RESULTS@#Anterior, posterior, lateral, and medial fracture maps were created. The majority of fracture lines (85.9%, 433/504) on the anterior maps were along the intertrochanteric line where the iliofemoral ligament was attached. In the medial plane, the majority of fracture lines (49.0%, 247/504) shown on the frequency spectrum included the turning point involving the third quadrant. In the posterior plane, the majority of fracture lines (52.0%, 262/504) involved the intertrochanteric crest from the greater to the lesser trochanter. In the lateral plane, the majority of fracture lines (62.7%, 316/504) involved the greater trochanter at the gluteus medius attachment.@*CONCLUSIONS@#The fracture patterns observed in the present study might be used to describe morphologic characteristics and aid with management strategies. Further classifications or modifications that incorporate the fracture patterns identified in this study may be used in future research.

<p><b>Background</b>Myocardial ischemia injury is one of the leading causes of death and disability worldwide. Cardiac fibroblasts (CFs) have central roles in modulating cardiac function under pathophysiological conditions. Activating transcription factor 3 (ATF3) plays a self-protective role in counteracting CF dysfunction. However, the precise function of CF-specific ATF3 during myocardial infarction (MI) injury/repair remains incompletely understood. The aim of this study was to determine whether CF-specific ATF3 affected cardiac repair after MI.</p><p><b>Methods</b>Fifteen male C57BL/6 wild-type mice were performed with MI operation to observe the expression of ATF3 at 0, 0.5, 1.0, 3.0, and 7.0 days postoperation. Model for MI was constructed in ATF3TGfl/flCol1a2-Cre+ (CF-specific ATF3 overexpression group, n = 5) and ATF3TGfl/flCol1a2-Cre- male mice (without CF-specific ATF3 overexpression group, n = 5). In addition, five mice of ATF3TGfl/flCol1a2-Cre+ and ATF3TGfl/flCol1a2-Cre- were subjected to sham MI operation. Heart function was detected by ultrasound and left ventricular remodeling was observed by Masson staining (myocardial fibrosis area was detected by blue collagen deposition area) at the 28 day after MI surgery in ATF3TGfl/flCol1a2-Cre+ and ATF3TGfl/flCol1a2-Cre- mice received sham or MI operation. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect cell proliferation/cell cycle-related gene expression in cardiac tissue. BrdU staining was used to detect fibroblast proliferation.</p><p><b>Results</b>After establishment of an MI model, we found that ATF3 proteins were increased in the heart of mice after MI surgery and dominantly expressed in CFs. Genetic overexpression of ATF3 in CFs (ATF3TGfl/flCol1a2-Cre+ group) resulted in an improvement in the heart function as indicated by increased cardiac ejection fraction (41.0% vs. 30.5%, t = 8.610, P = 0.001) and increased fractional shortening (26.8% vs. 18.1%, t = 7.173, P = 0.002), which was accompanied by a decrease in cardiac scar area (23.1% vs. 11.0%, t = 8.610, P = 0.001). qRT-PCR analysis of CFs isolated from ATF3TGfl/flCol1a2-Cre+ and ATF3TGfl/flCol1a2-Cre- ischemic hearts revealed a distinct transcriptional profile in ATF3-overexpressing CFs, displaying pro-proliferation properties. BrdU-positive cells significantly increased in ATF3-overexpressing CFs than control CFs under angiotensin II stimuli (11.5% vs. 6.8%, t = 31.599, P = 0.001) or serum stimuli (31.6% vs. 20.1%, t = 31.599, P = 0.001). The 5(6)-carboxyfluorescein N-hydroxysuccinimidyl ester assay showed that the cell numbers of the P2 and P3 generations were higher in the ATF3-overexpressing CFs at 24 h (P2: 91.6% vs. 71.8%, t = 8.465, P = 0.015) and 48 h (P3: 81.6% vs. 51.1%, t = 9.029, P = 0.012) after serum stimulation. Notably, ATF3 overexpression-induced CF proliferation was clearly increased in the heart after MI injury.</p><p><b>Conclusions</b>We identify that CF-specific ATF3 might contribute to be MI repair through upregulating the expression of cell cycle/proliferation-related genes and enhancing cell proliferation.</p>

ABSTRACT
AIM To establish an HPLC method for determining the contents of three constituents in Polygoni multiflori Radix Praeparata in plasma of atherosclerosis rats.METHODS After the rats were intragastrically administrated with Polygoni multiflori Radix Praeparata CMC-Na solution,the plasma was collected.The HPLC analysis was carried out on a 30 ℃ thermostatic Hypersil C1s column (250 mm ×4.6 mm,5 μm),with the mobile phase comprising of acetonitrile-0.03％ phosphoric acid flowing at 0.9 mL/min in a gradient elution manner,and the detection wavelength was set at 280 nm.DAS2.0 software was applied to drawing concentration-time curves and calculating pharmacokinetic parameters.RESULTS Stilbene glucoside,emodin and physcion showed good linear relationships within the ranges of 61.25-6 125 μg/L (r =0.999 8),12.6-3 150 μg/L (r =0.999 3) and 24.1-6 030 μg/L (r =0.999 5),respectively.The method recoveries were 99.5％-105.8％ with the RSDs of 1.3％-3.3％,while the extraction recoveries were 87.2％-96.3％ with the RSDs of 3.2％-5.9％.The pharmacokinetic behaviors of three constituents all accorded with two-compartment model,but their contents in plasma were much lower than those in medicinal material.CONCLUSION The bioavailabilities of stilbene glucoside,emodin and physcion are relatively low in plasma of atherosclerosis rats,which may be related to constituents' intestinal absorption after intragastric administration with Polygoni multiflori Radix Praeparata.
ABSTRACT
Polysaccharides from numerous traditional Chinese medicines have been proven as the bioactive ingredients and are hence used as the quality control markers. However, the assessment criteria always show a poor specificity, due to the lack of systematic comparison among the analogous herbs. In the present study, two similar materials, namely sea-tangle and sargassum, were selected as the model herbs to develop more specific methods for quality control. Two well-established methods, determination of the total polysaccharides content and monosaccharides composition analysis, were both employed. Based upon the quantitative results, the evaluation criteria of the polysaccharides contents of not less than 2.0% and 1.7% were proposed for sea-tangle and sargassum, respectively. Nine identical monosaccharide derivatives appeared on the HPLC chromatograms of the hydrolysis and derivatized solutions of the two drugs. Principal component analysis and orthogonal partial least squares discriminant analysis using the peak areas of monosaccharides derivatives as the variables were performed, and the results indicated that mannuronic acid and xylose with the opposite concentrations in the two drugs were the differential components. A discriminative criterion using the peak area ratio of these two monosaccharides derivatives was proposed for the qualitative identification. In conclusion, a more specific and quantitative quality control method was developed for sea-tangle and sargassum.

<p><b>OBJECTIVE</b>To evaluate the effect of arthroscopy-assisted minimally invasive management of bunion and hallux valgus deformities.</p><p><b>METHODS</b>Total 50 patients (53 feet) with bunion and hallux valgus deformities were treated under arthroscopy from July 2008 to July 2011, with an average age of 42.3 years old (ranging from 30 to 65 years old) involving 19 left feet, 28 right feet and 3 both feet. The American Orthopedic Foot and Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal(MP-IP) Scale Score was used to evaluate the therapeutic effect.</p><p><b>RESULTS</b>There were no complications such as hallux varus, hallux rigid and nerve or blood vessel injury. Clinically, AOFAS MP-IP Scale Score was increased from 62.19 ± 6.01 preoperatively to 88.26 ± 6.81 postoperatively.</p><p><b>CONCLUSION</b>Arthroscopy-assisted minimally invasive management appears to be a good procedure with advantages of less complication, little trauma and early rehabilitation for bunion and hallux valugs deformities.</p>

OBJECTIVES: Our study aimed to investigate the impact of fatigue on the severity of stroke and to explore the underlying mechanisms. METHODS: Fatigued male rats underwent middle cerebral artery occlusion and the infarcted brain area was determined. Then, coagulation parameters were assessed in the fatigued group and a control group. In addition, the level of fibrinogen was determined in rats deprived of sleep for various numbers of days. To study whether interleukin-6 was involved in fibrinogen synthesis during fatigue, we also measured levels of interleukin-6 in rats deprived of sleep for various numbers of days. Furthermore, brain injury by middle cerebral artery occlusion was measured in wild-type mice, interleukin-6-/- mice and wild-type mice treated with bezafibrate. RESULTS: More severe cerebral infarction was observed in the fatigued rats, resulting in an infarct ratio of 23.4%. The infarct ratio was significantly increased in the fatigued rats compared with that in the control group (8%, p<0.05). The level of fibrinogen was increased significantly in the fatigued rats compared with that in the control group. In addition, a marked reduction in fibrinogen level was observed in the fatigued interleukin-6-/- mice compared to their wild-type counterparts, whereas no difference was observed between fatigued wild-type mice and interleukin-6-/- rats treated with recombinant human interleukin-6. The reduction in brain injury due to middle cerebral artery occlusion during fatigue was observed in interleukin-6-/- mice and wild-type mice treated with bezafibrate. CONCLUSION: Fatigue could increase stroke severity and was associated with the interleukin-6-induced expression of fibrinogen. .

<p><b>OBJECTIVE</b>We aimed to analyze the impact of cardiovascular disease (CVD) deaths on life expectancy (LE) in Chinese population and estimate the percentage reduction in CVD mortality needed to increase LE by 1 year from the current level, a national target of health improvement.</p><p><b>METHODS</b>We used life tables, cause-elimination life tables, and age decomposition of LE with corrected mortality data from the National Disease Surveillance System in 2010.</p><p><b>RESULTS</b>LE at birth of Chinese people was 73.24 years in 2010. Women had a longer LE than men, and urban population had a longer LE than rural population. CVD deaths resulted in a 4.79-year LE loss and premature deaths in people aged 25 to 64 years were responsible for a substantial part of LE loss from CVD. Death from ischemic heart disease and cerebrovascular diseases accounted for 69.2% of LE loss from CVD deaths and death from cerebrovascular diseases was the largest contributor. In rural men, 51.1% LE loss from CVD deaths was caused by cerebrovascular diseases. If there were no changes in mortality rates for all other diseases, a 27.4% reduction in CVD mortality would increase LE by 1 year in Chinese population.</p><p><b>CONCLUSION</b>There is a considerable impact of CVD deaths on LE. A 1-year LE increase in the future requires at least a 27.4% reduction in CVD mortality from the current level. Targeting the rural population and tackling cerebrovascular diseases are important for reaching the national goal of health improvement.</p>
