ABSTRACT

There have been recent extensive studies and rapid advancement on the pathogenesis underlying idiopathic pulmonary fibrosis (IPF), and intricate pathogenesis of IPF has been suggested. The purpose of this study was to clarify the logical relationship between these mechanisms. An extensive search was undertaken of the PubMed using the following keywords: "etiology," "pathogenesis," "alveolar epithelial cell (AEC)," "fibroblast," "lymphocyte," "macrophage," "epigenomics," "histone," acetylation," "methylation," "endoplasmic reticulum stress," "mitochondrial dysfunction," "telomerase," "proteases," "plasminogen," "epithelial-mesenchymal transition," "oxidative stress," "inflammation," "apoptosis," and "idiopathic pulmonary fibrosis." This search covered relevant research articles published up to April 30, 2020. Original articles, reviews, and other articles were searched and reviewed for content; 240 highly relevant studies were obtained after screening. IPF is likely the result of complex interactions between environmental, genetic, and epigenetic factors: environmental exposures affect epigenetic marks; epigenetic processes translate environmental exposures into the regulation of chromatin; epigenetic processes shape gene expression profiles; in turn, an individual's genetic background determines epigenetic marks; finally, these genetic and epigenetic factors act in concert to dysregulate gene expression in IPF lung tissue. The pathogenesis of IPF involves various imbalances including endoplasmic reticulum, telomere length homeostasis, mitochondrial dysfunction, oxidant/antioxidant imbalance, Th1/Th2 imbalance, M1-M2 polarization of macrophages, protease/antiprotease imbalance, and plasminogen activation/inhibition imbalance. These affect each other, promote each other, and ultimately promote AEC/fibroblast apoptosis imbalance directly or indirectly. Excessive AEC apoptosis and impaired apoptosis of fibroblasts contribute to fibrosis. IPF is likely the result of complex interactions between environmental, genetic, and epigenetic factors. The pathogenesis of IPF involves various imbalances centered on AEC/fibroblast apoptosis imbalance.

ABSTRACT

Objective@#To investigate the prevalence of hyperactive behavior and risk factors among preschool children, and to provide a reference for early intervention of problem behavior.@*Methods@#A total of 7 982 children aged 3-6 were selected from 30 kindergartens by multi stage stratified cluster random sampling in 5 areas, Anhui Province, and their parents were surveyed with Conners Parent Rating Scales(PSQ) and Related factors questionnaire from June to July 2020.@*Results@#A tollay of 126 children were detected with hyperactivity behaviors, with a detection rate of 1.6%. The detection rate of boys (2.2%) was higher than that of girls (0.8%). The difference was statistically significant ( χ 2=26.51, P <0.01). Among 126 hyperactive children, 40(31.7%)had another type of behavior problem, and 82(65.1%)had two or more additional behavior problems. The results of Logistic regression analysis showed that boy( OR =2.85, 95% CI =1.88-4.30), sleep deprivation( OR =1.87, 95% CI =1.31-2.68), occupation of mother being farmer or otherwise( OR =1.81, 95% CI =1.11-2.94) were associated with more hyperactivity behavior. While, living with parents in the past six months ( OR =0.61, 95% CI =0.40-0.92) was associated with less hyperactivity behavior( P <0.05).@*Conclusion@#Early intervention of preschool children s behavior problems should focus on boys, maintain reasonable sleep time and increase parental care.

ABSTRACT

Objective To analyze the diagnosis and treatment of two imported cases with schistosomiasis haematobia, so as to provide insights into improving the diagnosis and treatment and avoiding misdiagnosis and mistreatment of imported schistosomiasis haematobia. Methods The medical records and epidemiological data pertaining to the two cases were collected. The stool and urine samples were collected for identification of Schistosoma eggs using the Kato-Katz technique and direct smear method after centrifugal precipitation, and blood samples were collected for detection of anti-Schistosoma antibody. Following definitive diagnosis, the patients were given praziquantel therapy. Results The patient 1, a Malagasy, was infected in Madagascar and returned to China for delivery. The case presented intermittent painless terminal hematuria symptoms, and showed no remarkable improvements following multiple-round treatments in several hospitals. In January 2017, she was found to be positive for anti-Schistosoma antibody, negative for feces test, and positive for S. haematobium eggs in urine test, and miracidia were hatched from eggs. Then, the case was diagnosed as schistosomiasis haematobia. Patient 2 worked in Republic of Malawi for many years, and presented intermittent painless terminal hematuria since October 2018; however, no definite diagnosis or effective treatment was received after admission to multiple hospitals. In March 2019, pathological examinations showed a number of eggs in the interstitium of the bladder mass, accompanied by a large number of eosinophils, which was consistent with schistosomiasis cystitis. In April 2019, he was tested positive for serum anti-Schistosoma antibody, negative for the fecal test, and had S. haematobium eggs in urine samples, with miracidia hatched from eggs. Then, the case was diagnosed as schistosomiasis haematobia. Following treatment with praziquantel at a dose of 60 mg/kg, all symptoms disappeared. Conclusions Overseas imported schistosomiasis haematobia is likely to be misdiagnosed. The training pertaining to schistosomiasis control knowledge requires to be improved among clinical professionals, in order to avoid misdiagnosis and mistreatment.

ABSTRACT

OBJECTIVE@#To study the effect of low-concentration paclitaxel (PTX) on transforming growth factor-β1 (TGF-β1)-induced collagen deposition outside rat pulmonary artery smooth muscle cells (PASMCs) and related mechanism.@*METHODS@#Primary rat PASMCs were divided into a blank control group (n=3), a model group (n=3), and a drug intervention group (n=3). No treatment was given for the blank control group. The model group was treated with TGF-β1 with a final concentration of 10 ng/mL. The drug intervention group was treated with PTX with a final concentration of 100 nmol/L in addition to the treatment in the model group. MTT colorimetry was used to measure cell proliferation. Quantitative real-time PCR was used to measure the relative mRNA expression of collagen type I (COL-I) and collagen type III (COL-III). ELISA was used to measure the OD value of COL-I and COL-III proteins. Western blot was used to measure the relative protein expression of COL-I, COL-III, and the key proteins of the TGF-β1/Smad3 signaling pathway (Smad3 and p-Smad3).@*RESULTS@#Compared with the blank control group, the model group had significant increases in proliferation ability, relative mRNA and protein expression of COL-I and COL-III, and relative protein expression of p-Smad3 (P0.05).@*CONCLUSIONS@#Low-concentration PTX exerts a marked inhibitory effect on TGF-β1-induced collagen deposition outside PASMCs, possibly by regulating the phosphorylation of Smad3 protein.

ABSTRACT

<p><b>BACKGROUND</b>Repetitive transcranial magnetic stimulation (rTMS) and event-related potentials (ERPs) are a noninvasive technique that widely used in neurophysiological field. Although rTMS has shown clinical utility for a number of neurological conditions, Recently,there was little understanding of the the efficacy of rTMS on Schizophrenia(SZ) and the change of ERP between before and after rTMS treatment. The objective of this study was to investigate the characteristics of N400, mismatch negativity (MMN), and P300 before and after treatment with rTMS in SZ.</p><p><b>METHODS</b>One hundred and twenty-seven SZ patients hospitalized in Shanghai Mental Health Center from March 2015 to July 2017, divided into two groups (85 patients were recruited as rTMS group and 42 were recruited as sham rTMS [ShrTMS] group) and 76 normal controls (NCs) who were the staff and refresher staff in our hospital were recruited at the same time. A Chinese-made rTMS and a Runjie WJ-1 ERPs instrument were used in the present experiment. N400 was elicited by congruent and noncongruent Chinese idioms. After rTMS treatment, N400, P300, and MMN characteristics were compared with those before treatment and NC group.</p><p><b>RESULTS</b>Compared with NC, the SZ patients exhibited delays in N400, P300, and MMN latency and decreased N400, P300, and MMN amplitudes in their frontal area (P < 0.05). After 25 rTMS treatments, N400 amplitudes in the frontal area (elicited by idioms with same phonic and different shape and meaning and with different phonic, shape, and meaning) were increased in the SZ patients (P < 0.05). However, there was no significant change in N400 before and after treatment with ShrTMS in SZ patients (P > 0.05). Amplitudes for MMN and target P300 also increased in SZ patients after rTMS treatment (P < 0.05).</p><p><b>CONCLUSIONS</b>Based on our preliminary findings, we believe that the combined usage of N400, MMN, and P300 could be a valuable index and an electrophysiological reference in evaluating the effects of rTMS treatment in SZ patients.</p>

ABSTRACT

Holistic integrative medicine (HIM), as one of the important ideas in the field of medicine, arouses great concern recently. HIM regards the human body as a whole, turns data and evidence in medical research back to facts, integrates technologies and experience developed in clinical research into medical skills. The repeated practices at the levels of fact, experience, and medical skills will generate true knowledge to solve the wide spread problems brought by linearized thinking and fragmented knowledge. With the development of highly divided medical disciplines, how to utilize and practice HIM has become a common concern of the medical community. Specialization of stomatology, which is a first level discipline like medicine, has also become a trend for years. However, holistic concept cannot be overlooked, especially in the development of oral medicine. This article aims at the communication and exchange of knowledge about HIM among dental professionals. In order to serve the patients better, the authors look forward to practicing the HIM concept in the field of oral medicine through the efforts of us all.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of direct moxibustion at Ganshu (BL18) on the serum concentrations of tumor specific growth factor (TSGF) and tumor necrosis factor α (TNF-α) in a rat model with precancerous lesion of primary hepatocellular carcinoma (HCC), so as to explore the mechanism of moxibustion underlying improvement of HCC.</p><p><b>METHODS</b>Sixty male Wistar rats were randomly divided into control group (n=10), model group (n=20), prevention group 1 (n=15) and prevention group 2 (n=15). The normal rats were injected with physiological saline as blank control. At the same time, the rats of other three groups were injected with diethylnitrosamine to establish the HCC model. Direct moxibustion with grain-sized moxa was applied to bilateral Ganshu acupoint of the rats in the prevention group 1 (1 treatment course, 20 days) and prevention group 2 (2 treatment courses, 40 days), 5 doses for each acupoint, 0.5 mg/dose, once every other day. At each time point (before model establishment, the end of 1st course prevention, the end of 2nd course prevention and the end of model establishment), serum levels of TSGF and TNF-α were detected using enzyme-linked immunosorbent assay.</p><p><b>RESULTS</b>Compared with the control group, there was a remarkably increase of serum TSGF and TNF-α contents in the model group at the end of the experiment (P<0.05). At the end of the 1st course of direct moxibustion, the contents of serum TSGF and TNF-α of rats in the prevention group 1 were significantly increased compared with that of the model group (P<0.05). At the end of the 2nd course of direct moxibustion, serum TSGF and TNF-α levels of rats in the model group were higher than the normal group with significantly difference (P<0.05), and the levels of TSGF and TNF-α in the prevention group 2 were significantly reduced in comparison with the model group (P<0.05).</p><p><b>CONCLUSION</b>It was possible that direct moxibustion could inhibit precancerous lesion and postpone hepatocarcinogenesis, and the therapeutic effect of two courses were better than one course.</p>

Positive c-met expression was significantly correlated with advanced TMN stages and lower tumor differentiation. Kaplan-Meier survival curve showed that the median survival time of c-met-positive patients was significantly reduced compared with that of c-met-negative patients (30.9 vs 48.2 months, P<0.05). COX regression analysis showed that c-met was a independent risk factor for the overall survival of the patients (HR: 2.34, 95% CI: 1.63-4.54, P<0.05).</p><p><b>CONCLUSION</b>A positive expression of c-met protein is significantly correlated with an advanced TMN stage, lower tumor differentiation and a poor prognosis, and may serve as a indicator for predicting the prognosis of ESCC.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigated the effects of bisoprolol pretreatment on hypoxia/reoxygenation (H/R)-induced injury in H9c2 cardiomyocytes.</p><p><b>METHODS</b>Cultured H9c2 cells were exposed to hypoxia for 6 h followed by reoxygenation for 2 h with or without pretreatments with bisoprolol or bisoprolol + LY294002. The cell survival was measured by MTT assay, and the cell apoptosis and levels of radical oxygen species (ROS) were evaluated with flow cytometry. The protein levels of phosphyorylated AKT and phosphorylated GSK3β in the cells were determined by Western blotting.</p><p><b>RESULTS</b>Compared with the normal control cells, the cells exposed to H/R injury showed significantly decreased cell survival and increased cell apoptosis and ROS production; pretreatment of the cells with bisoprolol significantly decreased the cell apoptotic rates and ROS production and obviously enhanced the cell survival and protein levels of p-AKT and p-GSK3β in the exposed cells. The protective effect of bsioprolol against H/R-induced cell injury was significantly attenuated by LY294002.</p><p><b>CONCLUSION</b>Bisoprolol can protect H9c2 cells against H/R-induced injury and oxidative stress by activating PI3K/AKT/Gsk-3β pathway to increase the phosphorylation of AKT and GSK3β and reduce ROS production.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the anesthetic effect and safety of ultrasound-guided thoracic paravertebral blockade in video-assisted thoracoscopic sympathectomy for treatment of palmar hyperhidrosis.</p><p><b>METHODS</b>A total of 120 patients undergoing video-assisted thoracoscopic sympathectomy for moderate or severe hyperhidrosis were randomized to receive ultrasound-guided thoracic paravertebral blockade (group A, n=60) or general anesthesia with tracheal intubation (group B, n=60). In both groups routine monitoring and radial artery catheterization were used. The patients in group A were given oxygen inhalation via a nasal tube after thoracic paravertebral blockade, and those in group B had intratracheal intubation. Blood gas analyses were conducted 5 min before and 5 min after the operation and the clinical outcomes and complications were recorded in each group.</p><p><b>RESULTS</b>All the patients completed the operations safely and none of the patients with thoracic paravertebral blockade required conversion to general anesthesia. Significant differences were recorded between groups A and B in anesthetic preparation time (6.26∓2.09 vs 46.32∓15.76 min), awakening time (6.26∓2.09 vs 46.32∓15.76 min), and mean hospitalization expense (6355.54∓426.00 vs 8932.25∓725.98 RMB Yuan). Compared with those in group B, the patients in group A showed a significantly lower rate of postoperative throat discomfort (0% vs 100%), a shorter monitoring time (2 h vs 12 h), and faster recovery time for food intake (2 h vs 6 h). The parameters of artery blood gas analysis both before and after the operation were similar between the two groups, but the postoperative variations differed significantly between the two groups in pH value and PaCObut not in PaO.</p><p><b>CONCLUSION</b>Ultrasound-guided thoracic paravertebral blockade is safe and effective in video-assisted thoracoscopic sympathectomy for palmar hyperhidrosis and is associated with less complications and better postoperative recovery.</p>

ABSTRACT

Objective Previous studies have shown that vitamin D deficiency is closely related to cardiac remodeling. How?ever, the underlying mechanisms have not been fully elucidated. Moreover, oxidative stress plays an important role on the pathologies of cardiac remodeling. The aim of this study was to explore the influence of VD deficiency on cardiac oxidative stress and the potential sig?nal pathway. Methods The male C57 mice ( 3 weeks old) were randomly divided into three groups: vitamin D deficiency ( VDD ) group ( vitamin D deficiency feed for 10 weeks) , vitamin D deficiency ( VDA) group ( vitamin D sufficiency feed for 10 weeks) and VDD+calcitriol ( CAL) group ( vitamin D deficiency feed for 10 weeks and then vitamin D sufficiency feed and calcitriol treatment for 10 weeks) . Results There were significant differences between the VDD group and the VDA group in the left ventricular end?diastolic diameter and left ventricular mass index (3.82±0.125 mm vs 3.748±0.092 mm, P<0.05) (119.30±8.54 vs 97.60±3.65, P<0.05). The number of myocardial cells stained with 8?OHDG was higher in the VDD group compared with the VDA group ( 65. 4 ± 2. 3 vs 21. 8 ± 1. 6, P<0.05) whereas was lower after calcitriol supplement. Furthermore, the expression of thioredoxin interacting protein (TXNIP) was sig?nificantly up?regulated and the ratio of p?ASK?1/ASK?1, cytochrome C release, and caspase3 activation were increased in the VDD group . Conclusion VDD can lead to cardiac oxidative injury and the up?regulation of TXNIP and the activation of ASK?1 related apoptotic signal cascade may be involved in this procedure.

ABSTRACT

Objective To evaluate the effect of high load application of atorvastatin on the clinical outcome of patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI).Methods Eighty patients diagnosed with AMI were continuously enrolled in this study and randomly divided into two groups:high dose group(n=40) and control group(n=40).Application of high load atorvastatin before operation in loading group.The levels of serum lipid and cardiac function were measured and analyzed.Results The levels of BNP((204±60.3) pg/mL vs.(328.3±67.5) pg/mL;t=1.938,P=0.0315) on 7 days after PCI and levels of LVEF((50.3±6.0)% vs.(56.9±7.3)%;t=2.169,P=0.019) on 1 month after PCI in high dose group were significantly better than those in control group.Correlation analysis showed that the administration of statin was negatively associated with levels of BNP(r=-0.157,P=0.021) on 7 days after PCI and positively associated with LVEF(r=-0.328,P=0.026) on 1 month after PCI.Conclusion The treatment of high dose statin before PCI may reduce the ischemia-reperfusion injury and prevent the no-reflow development,which therefore improve the cardiac function of AMI patients.
