ABSTRACT

Background/Aims@#Intrabolus pressures are important for esophageal bolus transport and may detect obstructed bolus flow. This study measured the effect esophageal outflow obstruction experimentally induce by a leg-lift protocol. @*Methods@#Twenty-five gastroesophageal reflux disease patients referred for esophageal manometry and a normal motility diagnosis were included. Supine liquid swallows were tested. Leg-lift protocol generated esophageal outflow obstruction by increasing abdominal pressure. Esophageal pressure topography and intrabolus pressure metrics were calculated. These included, (1) mid-domain bolus distension pressure during esophageal emptying (DPE, mmHg) and (2) ramp pressure (mmHg/sec), generated by compression of the bolus between the peristaltic contraction and esophagogastric junction (EGJ). @*Results@#EGJ relaxation pressure was increased by leg-lift from 13 (11-17) to 19 (14-30) mmHg (P< 0.005) and distal contractile integral also increased from 1077 (883-1349) to 1620 (1268-2072) mmHg · cm · sec (P < 0.001) as a physiological response to obstruction. All bolus pressures were increased by leg lift; DPE increased from 17 (15-20) to 27 (19-32) mmHg (P< 0.001), and ramp pressure increased from 3 (1-4) to 5 (2-9) mmHg/sec (P < 0.05). @*Conclusion@#Measuring pressures within the intrabolus domain can quantify changes related to obstruction to outflow and may serve as adjunct measures for confirming a diagnosis EGJ outflow obstruction.

ABSTRACT

Objective:To study the effect of physical therapy and heel sound feedback on lower limbs motor function, mobility and activities of daily living (ADL) for stroke patients based on International Classification of Functioning, Disability and Health (ICF) core set. Methods:From April, 2018 to May, 2020, 113 stroke patients with motor dysfunction were divided into ischemia group (n = 67) and hemorrhagia group (n = 46) according to the cause of stroke. They received physical therapy for lower limbs and heel sound feedback for eight weeks, and assessed with ICF core set for stroke-gait, Fugl-Meyer Assessment-Lower Extremities (FMA-LE), Timed 'Up and Go' Test (TUGT), and modified Barthel index (MBI) before and after intervention. Results:The main effect of time was significant for qualifiers of ICF core set for stroke-gait, the scores of FMA-LE and MBI, and TUGT time (F > 100.59, P < 0.001), and it improved time by time as Post Hoc test. The main effect of groups was not significant (F < 2.29, P > 0.05), nor as Post Hoc test. The interactive effect between time and groups was significant for TUGT time (F = 6.45, P < 0.01), perhaps improved more in the hemorrhagia group, however, the interactive effect was not significant for the others. Conclusion:Physical therapy and heel sound feedback can improve motor function of lower limb, mobility and ADL for stroke patients.

ABSTRACT

OBJECTIVE@#To assess the association of CYP2C19 and CYP3A5 gene polymorphisms with the risk of myocardial infarction.@*METHODS@#Five hundred patients with myocardial infarction and 500 healthy controls were randomly selected. Fluorescent PCR and Sanger sequencing were used to detect the CYP2C19 and CYP3A5 gene polymorphisms. Logistic regression was used to analyze the correlation between the polymorphisms and myocardial infarction. Quanto software was used to evaluate the statistical power.@*RESULTS@#The two groups had significant difference in the frequency of AG, GG genotypes and A allele of the CYP2C19 gene rs4986893 locus and the AA, AG, GG genotypes and G allele of the CYP3A5 gene rs776746 locus ( P<0.05), but not in the frequency of genotypes and alleles of CYP2C19 gene rs4244285 and rs12248560 loci, and the AA genotype of the rs4986893 locus. After correction for age, gender, and body mass index, Logistic regression indicated that the AG genotype and A allele of the CYP2C19 gene rs4986893 locus, and the GG genotype and G allele of CYP3A5 gene rs776746 locus are associated with susceptibility of myocardial infarction, while rs4986893 GG genotype and AA and AG genotypes of rs776746 may confer a protective effect. Based on the sample size and allele frequency, analysis with Quanto software suggested that the result of this study has a statistical power of 99%.@*CONCLUSION@#CYP2C19 and CYP3A5 gene polymorphisms may increase the risk for myocardial infarction.

ABSTRACT

Objective:To evaluate the safety and long-term efficacy of endoscopic resection of gastric stromal tumors with a diameter of >2-4 cm.Methods:The clinical data of 307 patients, who underwent endoscopic or surgical resection and pathologically confirmed to be gastric stromal tumors with a diameter ≤4 cm in Fujian Provincial Hospital, Jinshan Branch of Fujian Provincial Hospital or Fujian Geriatric Hospital from January 2014 to December 2019, were collected. The propensity score matching (1∶1) was performed for the cases with the tumor size of >2-4 cm.Then the incidence of adverse events related to the operation and clinical outcomes were compared between 41 patients in the endoscopic group and 41 patients in the surgical group.Results:Compared with the surgical group, the median operation time in the endoscopic group was significantly shorter (58.0 min VS 108.0 min, Z=-4.789, P<0.001), and the median hospitalization cost was significantly lower (22.7 thousand yuan VS 42.0 thousand yuan, Z=-7.164, P<0.001). There were no significant differences in postoperative fasting time or postoperative hospitalization time between the two groups ( P>0.05). Complications occurred in 7 cases (17.1%) in the endoscopy group, including 5 cases of postoperative acute infection, 1 case of postoperative perforation, and 1 case of postoperative bleeding; all 9 cases (22.0%) in the surgical group developed postoperative acute infection. There was no significant difference in the overall incidence of complications between the two groups ( χ2=0.311, P=0.577). Tumors in both groups were completely removed with negative resection margins. The follow-up time of the endoscopy group was 34.3±15.6 months, and that of the surgical group was 42.2±20.2 months. No recurrence or distant metastasis was observed during the follow-up period in the two groups. Conclusion:Endoscopic resection of large gastric stromal tumor (range>2-4 cm) is safe and effective in the long term, which can be used as one of the methods for gastrointestinal stromal tumors.

ABSTRACT

OBJECTIVE: To observe the neurotoxicity and hematotoxicity of maternal exposure to 1-bromopropane(1-BP) on the offspring rats by the breast-feeding route. Method A total of eight specific pathogen free female rats and their 64 male newborn rats were divided into the control group and the exposure group, with four lactation female rats and their 32 male newborn rats in each group. The female rats in exposure group were intragastrically administered with 700.00 mg/kg body mass of 1-BP during lactation, and the control group was given equal volume of corn oil for 21 days, once a day. The body mass of female rats and their offspring rats were measured during the exposure period. After exposure, the Morris water maze and the open field tests were performed in male offspring. The blood samples of offspring were collected for blood routine and blood biochemical indexes detection. The histopathological examination was performed in the hippocampus in the male offspring. RESULTS: A litter of eight pups in the exposure group began to die one day after the mother rat was exposed to 1-BP, and all rats died on the ninth day after exposure. There was no significant difference in the body mass of female rats between the exposure group and the control group(P>0.05). The body mass of offspring rats in the exposure group was lower than that in the control group at the same time point from the first day to the 21 st day of the female rats exposed to 1-BP(all P<0.05). In the orientation navigation experiment, the escape latency time on the first, the second day and the total distance on the first day in the offspring of the exposure group were significantly prolonged than those in the control group at the same time points(all P<0.05). The number of times of crossing the platform of offspring rats in the exposure group was less than that in the control group in the spatial exploration test(P<0.01). In the open field test, there was not statistical significance of the activity, rest time ratio, total distance, the distance ratio and time ratio in the central region in the offspring between the two groups(all P>0.05). The counts of white blood cells, neutrophils, lymphocytes, and average red blood cell width, platelet ratio and average platelet volume of the offspring of the exposure group decreased(all P<0.05), the serum levels of globulin, total protein, triacylglycerol and total bilirubin decreased(all P<0.05), and the albumin/globulin ratio and serum glucose level increased(all P<0.05), when compared with that of the control group. Histopathological examination results showed that the nerve fibers were loose in the hippocampal dentate gyrus area, and there were necrotic neurons and loss of nerve fibers in the CA1 area of the offspring rats. CONCLUSION: Maternal exposure to 1-BP during lactation can induce neurotoxicity and hematotoxicity to offspring rats. The neurotoxicity mainly caused damage to the central nerve system, which affected the learning and memory function of the offspring rats. The reason may be related to the damage caused by 1-BP on the hippocampal function.

ABSTRACT

The origins of 9 species of the Chinese medicinal materials in the 2015 edition of the Chinese pharmacopoeia(ChP) has revised in the 2020 edition of ChP. The revision is based on the investigation and textual research on the problems found after screening the original plants, animals or minerals of all the Chinese medicinal materials in the 2015 edition. Among them the Chinese names of Alismatis Rhizoma, Cassiae Semen, Coicis Semen, Corydalis Bungeanae Herba and Echinopsis Radix all do not match to the Latin scientific names, and also do not match the name of the actual medicinal origins. In addition, Alismatis Rhizoma has the omission of original plant. There is confusion about the Chinese name and the family name of the original insect of Cera Chinensis. The original mineral of Gypsum Fibrosum has the wrong group names. Alumstone and melanterite, the original mineral of Alumen and Melanteritum respectively, of which the group names are missing. To solve these problems, field survey and literature research were conducted on the medicinal materials and their origins. The source of these problems are explored. The correct origins and the Chinese names or Latin names are all determined according to the research results to the situation, in which the Chinese and Latin names of the original plants of the medicinal materials do not match. The correct family name and group name are obtained through textual research by taxonomy if the names are confused or mis-sing. The scientific evidence and correct results of revision in the 2020 edition of ChP are determined at last.

ABSTRACT

Abstract Brazil has become the epicenter of the COVID-19 pandemic in the Global South-a pandemic that disproportionately affects vulnerable populations, especially those detained and imprisoned. Legal institutions are struggling to respond. In this paper, we focus on the National Council of Justice's Recommendation 62, issued March 17, 2020, which recommends that judges take several measures to reduce the risk of COVID-19 infection in prisons. We test this recommendation's impact by looking at habeas corpus decisions in the São Paulo Court of Justice. The exploratory findings presented here indicate that Recommendation 62 has little impact on habeas decisions. In general, citing the recommendation does not lead the Court to grant early release or house arrest to those detained, and most habeas actions are decided against petitioners. This is true even when petitioners claim to be part of a risk group, or their alleged offense did not involve violence or serious threat-factors that should favor habeas relief under Recommendation 62.


Resumen Brasil se ha convertido en el epicentro de la pandemia de COVID-19 en el Sur global, una pandemia que afecta desproporcionadamente a las poblaciones vulnerables, especialmente a las detenidas y encarceladas. A las instituciones jurídicas les resulta difícil ofrecer una respuesta adecuada. En este artículo, analizamos una de esas respuestas, la Recomendación 62 del Consejo Nacional de Justicia, emitida el 17 de marzo de 2020 y que recomienda que jueces tomen diferentes medidas para reducir el riesgo de infección por COVID-19 en las prisiones. Evaluamos el impacto de esta recomendación analizando las decisiones sobre habeas corpus del Tribunal de Justicia de São Paulo. Los hallazgos exploratorios presentados aquí indican que la Recomendación 62 tiene poco impacto en estas decisiones. En general, citar la recomendación no lleva al Tribunal a conceder la libertad anticipada o el arresto domiciliario a las personas detenidas y la mayoría de los habeas corpus son decididos en contra de los demandantes. Esto es cierto incluso cuando estas personas afirman ser parte de los grupos de riesgo o que su supuesto crimen no implica violencia o amenaza grave, factores que deberían favorecer las decisiones por la concesión de los habeas corpus, de acuerdo con la Recomendación 62.

Os achados exploratórios aqui apresentados indicam que a Recomendação 62 tem pouco impacto nestas decisões. Em geral, citar a recomendação não leva o Tribunal a conceder liberdade antecipada ou prisão domiciliar às pessoas presas e a maioria dos habeas corpus são decididos contra demandantes. Isso é verdade mesmo quando estas pessoas afirmam fazer parte de algum dos grupos de risco ou que seu suposto delito não envolvera violência ou grave ameaça — fatores que deveriam favorecer decisões pelo provimento do habeas corpus, segundo a Recomendação 62.

ABSTRACT

Objective:To evaluate the efficacy and safety of budesonide viscous suspension (BVS) in preventing extensive esophageal stenosis after endoscopic submucosal dissection(ESD).Methods:Data of 62 cases of early esophageal neoplasms or precancerous lesions receiving ESD whose postoperative mucosal defects were more than half the circumference of the esophageal lumen at Fujian Provincial Hospital from October 2014 to December 2018 were retrospectively studied. The patients were divided into the BVS group who received BVS therapy (n=24) and the control group who received no intervention (n=38). The incidence of postoperative stenosis, the number of bougie dilation procedures and complications were compared between the two groups. Risk factors for postoperative stricture were analyzed by logistic regression.Results:The incidence of postoperative stenosis [16.7% (4/24) VS 47.3% (18/38), P=0.005], the number of bougie dilation procedures (1.50±0.58 VS 2.70±1.09, P=0.039) in the BVS group were significantly lower than those in the control group. No serious adverse events such as perforation or massive hemorrhage related to BVS were observed in the BVS group. Multivariate logistic regression analysis showed circumferential extension ≥3/4 ( OR=37.970, 95% CI: 6.338-227.482) and non-intervention with BVS( OR=20.962, 95% CI: 3.374-130.243) were the independent risk factors for esophageal stricture after ESD. Conclusion:Administration of BVS is an effective and safe method to reduce the incidence of stenosis and the number of bougie dilation procedures for extensive esophageal stenosis after ESD.

ABSTRACT

Objective:To preliminarily study the effect of Q self-traction endoscopic submucosal dissection (Q-ESD) on treatment of large early esophageal cancer (EEC).Methods:A retrospective analysis was performed on the data of 82 cases of large EEC (single lesion>1/2 cross-section diameter or longitudinal diameter length >5 cm) who underwent ESD on Fujian Provincial Hospital between January 2015 and December 2018. According to the treatment schedule, patients were divided into the conventional ESD group (n=44) and the Q-ESD group (n=38). The procedural area, time, and speed, en bloc resection rate, complete resection rate and complications of the two groups were analyzed.Results:All of the 82 lesions were resected completely under endoscope. There was no statistical difference in the procedural area [779.8 (329.9-2 552.5)mm 2 VS 875.7 (417.8-1 914.8)mm 2, U=155, P=0.636], procedural time [63 (41-177)min VS 59 (42-169)min, U=171, P=0.167] and complete resection rate [94.7% (36/38) VS 93.2% (41/44), χ2=0.086, P=0.769] between the Q-ESD group and the conventional ESD group. Compared with the conventional ESD group, the Q-ESD group had a faster dissection speed [14.9 (5.4-20.8) mm 2/min VS 9.0 (5.0-19.5) mm 2/min, U=142, P=0.035], lower muscularis propria injury rate [7.9% (3/38) VS 27.3% (12/44), χ2=5.123, P=0.023], and a lower stricture rate [5.3% (2/38) VS 20.5% (9/44), χ2=4.051, P=0.044]. No other adverse events occurred except for one case of perforation in the conventional ESD group. Conclusion:The new traction technique of Q-ESD is a safe and effective treatment for large EEC.

ABSTRACT

Leukemia is a common and harmful disease for humans. Chemotherapy is the main treatment method. During the decades of experience, the clinicians have found that these drugs work well, but obvious individual differences occur in different patients. Some concerns of the clinicians exist such as how to learn more about the factors that may induce drug resistance and adverse reactions, and how to improve the efficacy of chemotherapy drugs, reduce drug resistance and side effects. This paper reviews the effect of genetic factors of commonly-used chemotherapeutic drugs for acute leukemia, aiming to provide a theoretical foundation for personalized administration of these chemotherapeutic drugs.

ABSTRACT

The compatibility of Chinese materia medica (CMM) studies the relations between herbs and their interacting effects. With complex medications for individuals and massive CMM data, it is difficult for traditional data mining methods to reveal the inherent rules in compatibility analysis. This paper with the theory of complex network constructs a “formulae-herb” network to analyze herb combinations based on the overlapping communities for internal rules in CMM classic formulae. Based on the complex network, the formulae can be abstracted to a graph and represented by nodes and edges, herbs as nodes, and the relationships of herbs as edges. The edges were weighted according to the frequency of co-occurrence of two herbs. “Formulae-herb” network was then constructed based on all formulae in the study. A definition “herb influence” was introduced into the network to identify important herb nodes, with which a method of “formulae-herb” network division was introduced based on overlapping communities to discover the structure of the herb relations. Finally, the inherent laws in the community were discussed. A “formulae-herb” network was constructed based on 112 formulae from Treatise on Cold Damage. Herbs with high influence are in line with Zhang Zhong-Jing's medication principle of “combining cold and warm, use of pungent, sweet and bitter together”. This paper also incorporates FCM (fuzzy C-means) algorithm to discover the commonly used herb groups hidden in the medication. A model of treating Shaoyin syndrom was constructed as an application. Herbs with high influence were in line with the treating method of “warming meridian and reinforcing yang, promoting urination and draining dampness”. The result showed that multiple herb groups were clearly classified. “Formulae-herb” network model showed high quality overlapping community structures, the analysis of inherent laws in the community can provide basis for the exploration of compatibility rules of herbs and internal rules in formulae regularities.

ABSTRACT

Anthraquinone and its derivatives are very important secondary metabolites in plants. They have many functions such as photoprotection and improvement of plant disease resistance. They also have very important applications in the fields of medicine and chemical engineering. Efficiently and quickly obtaining anthraquinones and improving the synthesis efficiency of anthraquinones in plants have become one of the research focuses of modern synthetic biology. However, the synthetic pathway of anthraquinones is more complicated. At present, it is generally believed that anthraquinones are formed in plants by the shikimic acid/o- succinylbenzoic acid pathway and polyketone pathway. This article focuses on the recent research advances in the skeleton synthesis of anthraquinone via shikimic acid/o-succinylbenzoic acid pathway and polyketone pathway in plants, and provides a certain theoretical basis for studying the synthesis and regulation of anthraquinone metabolites in plants.

ABSTRACT

Acute kidney injury (AKI) and hepatorenal syndrome (HRS) are serious complications in patients with end-stage liver disease, with renal injury as the main manifestation. They are interrelated, but also different from each other. There are several types of AKI, i.e., prerenal AKI, intrarenal or intrinsic AKI, and post-renal AKI, and type 1 HRS is considered a special type of AKI. There are different therapies for different types of AKI. With the improvement in the diagnostic criteria for AKI and chronic kidney disease in recent years, the diagnostic criteria and classification of HRS have also been updated. As for pathogenesis, systemic inflammation caused by intestinal bacterial translocation is attracting more and more attention. HRS was considered functional renal injury in the past, but recent evidence suggests the existence of structural injury. Vasoconstrictor combined with albumin is the main therapeutic drug for HRS. This article reviews the diagnosis and treatment of AKI in end-stage liver disease and the recent advances in the diagnostic criteria, classification, pathology, pathogenesis, and treatment of HRS.
