Cytotoxic effects of crotoxin from Crotalus durissus terrificus snake in canine mammary tumor cell lines

Background: Mammary gland tumors are the most prevalent neoplasm in intact female dogs, and they are good natural models to study comparative oncology. Most canine mammary malignancies, as in women, are commonly refractory to conventional therapies and demand continuous new therapeutic approaches. Crotalus durissus terrificus, also called rattlesnake, has more than 60 different proteins in its venom with multiple pharmaceutical uses, such as antitumor, antiviral, and antimicrobial action. Crotoxin, a potent β-neurotoxin formed by the junction of two subunits, a basic subunit (CB-PLA2) and an acidic subunit (crotapotin), has already been reported to have anticancer properties in different types of cancers. Methods: In this work, we describe the cytotoxic potential of crotoxin and its subunits compared to doxorubicin (drug of choice) in two canine mammary carcinoma cell lines. Results: Crotoxin, CB-PLA2, crotalic venom, and doxorubicin decreased cell viability and the ability to migrate in a dose-dependent manner, and crotapotin did not present an antitumoral effect. For all compounds, the predominant cell death mechanism was apoptosis. In addition, crotoxin did not show toxicity in normal canine mammary gland cells. Conclusion: Therefore, this work showed that crotoxin and CB-PLA2 had cytotoxic activity, migration inhibition, and pro-apoptotic potential in canine mammary gland carcinoma cell lines, making their possible use in cancer research.

Comparison between the ion-specific electrode and SPADNS methods for analysis of fluoride concentration in the water supply

The maintenance of adequate fluoride (F) concentration in the public water supply is fundamental for ensuring that the community use of F can reach the maximum benefit for caries control and minimum risk for dental fluorosis. Thus, surveillance systems must use accurate and valid analytical methods to determine F concentration and, according to the literature, give preference to the ion-specific electrode (F- ISE) analysis. Aim: The objective of this study was to compare the accuracy of the ISE and SPADNS methods in the determination of the F concentration in the same water sample. Methods: Duplicate water samples were taken from 30 sampling sites in the municipality of Maringá, state of Paraná, monthly for 12 months, totaling 276 samples. An aliquot was analyzed by the FOP-UNICAMP Oral Biochemistry laboratory, using the F- ISE method, and the other one, by the SANEPAR laboratory in Maringá/PR, using the SPADNS method. Descriptive analysis and Pearson's correlation test were applied, with a significant level of p<0.05. Results: Results were expressed as ppm F (mg F/L), and a very strong positive correlation (r= 0.91; p<0.001) was detected between the two methods of analysis. Conclusion: Our findings suggest that the determination of f luoride concentration in water can be made with accuracy by the SPADNS method, a standardized analysis protocol

A comparative analysis between Mexican and Chinese health systems / Un análisis comparativo entre los sistemas de salud de México y China

Abstract Objective: The comparative network analysis of national health macrosystems is an area whose academic development has not reached due relevance if its influence on decision-making related to the design of public health policies is considered; the establishment of comparative elements between two socially, economically and culturally distant countries, such as Mexico and China, is a complex process given the difficulty of locating equivalent evaluation indicators among some of its elements. Materials and methods: The present work reflects on the similarities and dissimilarities between the national health systems, with an impact on the care provided to the most vulnerable population segments, applying a comparative nodes and networks analysis considering social and economic factors. Results: The network analysis shows that, for practical purposes, the nodes considered in the Mexican health system is superior to those nodes identified in the Chinese health system in terms of quality, mainly in nodes such as convenience of the location, using cutting-edge technology in health institutions and the skill and competence of medical personnel; conversely, the Chinese system is superior to the Mexican in terms of efficiency, mainly involuntary co-payment insurance systems to reduce the catastrophic health expenditure of the vulnerable rural population. Conclusions: The conclusions drawn may serve for subsequent studies to identify opportunities for improvement, correlations and/or trends that could be implemented in the Mexican health system, once the pertinent feasibility studies have been carried out.

Resumen Objetivo: El análisis de redes comparativo de macrosistemas nacionales de salud es un ámbito cuyo desarrollo académico no ha alcanzado la relevancia debida si se considera su influencia en la toma de decisiones relativas al diseño de políticas de salud pública. Así, el establecimiento de elementos comparativos entre dos países social, económica y culturalmente distantes, como México y China, es un proceso complejo dada la dificultad de ubicar indicadores equivalentes de evaluación entre algunos de sus elementos. Materiales y método: El presente trabajo reflexiona sobre las similitudes y diferencias entre los mencionados sistemas nacionales de salud, con incidencia en la atención que se brinda a los segmentos poblacionales más vulnerables, aplicando un análisis comparativo de nodos y redes considerando factores sociales y económicos. Resultados: El análisis de red muestra que, para efectos prácticos, los nodos considerados en el sistema de salud mexicano son superiores a los nodos identificados en el sistema de salud chino en términos de calidad, principalmente en nodos como conveniencia de la ubicación, utilizando tecnología de punta en instituciones de salud y la habilidad y competencia del personal médico; Por el contrario, el sistema chino es superior al mexicano en términos de eficiencia, principalmente sistemas de seguro de copago involuntario para reducir el gasto catastrófico en salud de la población rural vulnerable. Conclusiones: Las conclusiones extraídas podrán servir a estudios posteriores para identificar oportunidades de mejora, correlaciones y/o tendencias que pudieran implementarse en el sistema mexicano de salud, una vez efectuados los estudios de viabilidad pertinentes.

Deep anterior lamellar keratoplasty versus penetrating keratoplasty: comparison of clinical outcomes in contralateral eyes / Ceratoplastia lamelar anterior profunda versus ceratoplastia penetrante: comparação dos resultados clínicos em olhos contralaterais

ABSTRACT Purpose: This study aimed to compare the clinical outcomes following deep anterior lamellar keratoplasty and penetrating keratoplasty in contralateral eyes of the same patients. Methods: In this retrospective, comparative case series, clinical outcome data included best-corrected visual acuity, refractive spherical equivalent, refractive astigmatism, endothelial cell density, endothelial cell loss, central corneal thickness, and intraocular pressure, which were evaluated at 6, 12, 24, and 36 months after deep anterior lamellar keratoplasty and penetrating keratoplasty. Additionally, complications were assessed. Results: Fifty-two eyes (26 patients) were included, of which 19 patients had keratoconus, 6 had stromal dystrophy, and 1 had post-laser-assisted in situ keratomileusis ectasia. The mean follow-up was 44.1 ± 10.5 months in the deep anterior lamellar keratoplasty Group and 47.9 ± 11.9 months in the penetrating keratoplasty Group. No significant differences were observed in the mean best-corrected visual acuity, refractive spherical equivalent, refractive astigmatism, and central corneal thickness between the deep anterior lamellar keratoplasty and penetrating keratoplasty Groups during follow-up. The endothelial cell density was significantly higher in the deep anterior lamellar keratoplasty Group than in the penetrating keratoplasty Group at 24 and 36 months postoperatively (p=0.022 and 0.013, respectively). Endothelial cell loss was significantly lower in the deep anterior lamellar keratoplasty Group than in the penetrating keratoplasty Group at 24 and 36 months postoperatively (p=0.025 and 0.001, respectively). Intraocular pressure was significantly lower in the deep anterior lamellar keratoplasty Group than in the penetrating keratoplasty Grroup at 6 months postoperatively (p=0.015). Microperforation occurred in 4 eyes (15%) during deep anterior lamellar keratoplasty surgery; however, penetrating keratoplasty was not required. No endothelial rejection occurred in the penetrating keratoplasty Group during follow-up. Conclusions: Over the 3-year follow-up, endothelial cell loss and intraocular pressure in the deep anterior lamellar keratoplasty Group were significantly lower than those in the penetrating keratoplasty Group, while visual and refractive results were similar.

RESUMO Objetivo: Este estudo teve como objetivo comparar os resultados clínicos após ceratoplastia lamelar anterior profunda e ceratoplastia penetrante nos olhos contralaterais dos mesmos pacientes. Métodos: Nesta série de casos comparativa e retrospectiva, avaliaram-se os seguintes dados de resultados clínicos: melhor acuidade visual corrigida, equivalente esférico refrativo, astigmatismo refrativo, densidade de células endoteliais, perda de células endoteliais, espessura central da córnea e pressão intraocular. Esses dados foram avaliados aos 6, 12, 24 e 36 meses após ceratoplastia lamelar anterior profunda e ceratoplastia penetrante. Também foram avaliadas as complicações. Resultados: Foram incluídos 52 olhos (26 pacientes), sendo que 19 pacientes apresentavam ceratocone, 6 apresentavam distrofia estromal e 1 apresentava ectasia após ceratomileuse in situ assistida por laser. O tempo médio de acompanhamento foi de 44,1 ± 10,5 meses no grupo da ceratoplastia lamelar anterior profunda e 47,9 ± 11,9 meses no grupo da ceratoplastia penetrante. Nenhuma diferença significativa foi observada nas médias da melhor acuidade visual corrigida, equivalente esférico refrativo, astigmatismo refrativo e espessura central da córnea entre os grupos da ceratoplastia lamelar anterior profunda e da ceratoplastia penetrante durante o acompanhamento. A densidade de células endoteliais foi significativamente maior no grupo da ceratoplastia lamelar anterior profunda que no grupo da ceratoplastia penetrante aos 24 e 36 meses de pós-operatório (p=0,022 e 0,013, respectivamente). A perda de células endoteliais foi significativamente menor no grupo da ceratoplastia lamelar anterior profunda que no grupo da ceratoplastia penetrante aos 24 e 36 meses de pós-operatório (p=0,025 e 0,001, respectivamente). A pressão intraocular foi significativamente menor no grupo da ceratoplastia lamelar anterior profunda que no grupo da ceratoplastia penetrante aos 6 meses de pós-operatório (p=0,015). Ocorreu microperfuração em 4 olhos (15%) durante a cirurgia de ceratoplastia lamelar anterior profunda; entretanto, a ceratoplastia penetrante não foi necessária. Não ocorreu nenhuma rejeição endotelial no grupo da ceratoplastia penetrante durante o período de acompanhamento. Conclusões: Durante o acompanhamento de 3 anos, a perda de células endoteliais e a pressão intraocular foram significativamente menores no grupo da ceratoplastia lamelar anterior profunda que no grupo da ceratoplastia penetrante, mas os resultados visuais e refrativos foram semelhantes.

Pediatric canalicular laceration repair using the Mini Monoka versus Masterka monocanalicular stent / Correção de laceração canalicular pediátrica usando os stents monocanaliculares Mini-Monoka versus Masterka

ABSTRACT Purpose: One of the most important disadvantages of using Mini Monoka stents in pediatric canalicular laceration repair is premature stent loss. In this study, we aimed to compare clinical outcomes between the use of Mini Monoka and Masterka monocanalicular stents in children and discuss the potential causes of premature stent loss. Methods: The medical records of 36 patients who underwent surgical repair of canalicular lacerations were retrospectively reviewed. Children aged <18 years who underwent canalicular laceration repair with either Mini Monoka or Masterka and had at least 6 months of follow-up after stent removal were included in the study. The patients' demographics, mechanism of injury, type of stent used, premature stent loss, and success rate were analyzed. Success was defined as stent removal without subsequent epiphora and premature stent loss. Results: Twenty-seven children fulfilled our study criteria, and their data were included in the analyses. Mini Monoka was used in 14 patients (51.9%), whereas Masterka was used in 13 patients (48.1%). The preoperative clinical features, including age, sex, and mechanism of injury, were similar between the two groups. The mean age was 8.3 ± 5.5 years in the Mini Monoka group and 7.8 ± 5.9 years in the Masterka group (p=0.61). Three patients in the Mini Monoka group (21.4%) underwent reoperation due to premature stent loss. No premature stent loss was observed in the Masterka group. As a result, the rate of success was 78.6% in the Mini Monoka group, whereas it was 100% in the Masterka group (p=0.22). Conclusions: Even though the two groups did not show any statistically significant difference in success rate, we did not observe any premature stent loss in the Masterka group. Further studies with larger and randomized series are warranted to elaborate on these findings.

RESUMO Objetivo: Uma das desvantagens mais importantes do uso de stents Mini Monoka no reparo de lacerações canaliculares pediátricas é a perda prematura do stent. Neste estudo, objetivamos comparar os resultados clínicos dos stents monocanaliculares Mini Monoka e Masterka em crianças e discutir as possíveis causas da perda prematura do stent. Métodos: Foram incluídos nesta revisão retrospectiva 36 pacientes <18 anos de idade que se submeteram ao reparo cirúrgico de uma laceração canalicular com um stent Mini Monoka ou Masterka e tiveram pelo menos 6 meses de acompanhamento após a remoção do stent. Foram analisados os dados demográficos, o mecanismo da lesão, o tipo de stent utilizado, a ocorrência de perda prematura de stent e o sucesso da intervenção. O sucesso foi definido como a ausência de epífora após a remoção do stent, sem a perda prematura deste. Resultados: Vinte e sete pacientes preencheram os critérios do presente estudo e foram incluídos nas análises. O stent Mini Monoka foi usado em 14 pacientes (51,9%), enquanto o Masterka foi usado em 13 pacientes (48,1%). As características clínicas pré-operatórias, incluindo idade, sexo e mecanismo de lesão, foram semelhantes entre os dois grupos. A média de idade foi de 8,3 ± 5,5 anos no grupo Mini Monoka e de 7,8 ± 5,9 anos no grupo Masterka (p=0,61). Três pacientes do grupo Mini-Monoka (21,4%) tiveram que ser operados novamente por perda prematura do stent. Nenhuma perda prematura do stent foi observada no grupo Masterka. Como resultado, a taxa de sucesso foi de 78,6% no grupo Mini Monoka e de 100% no grupo Masterka (p=0,22). Conclusões: Embora nenhuma diferença estatisticamente significativa tenha sido detectada entre os dois grupos em termos de taxas de sucesso, não observamos nenhuma perda prematura de stent no grupo Masterka. São necessários mais estudos, com séries maiores e randomizadas, para chegar a maiores conclusões sobre esses achados.

A neglected normal anatomical structure in mammal: a study in bats and tree shrews / Una estructura anatómica normal desatendida en mamíferos: un estudio en murciélagos y musarañas arborícolas

SUMMARY: The myodural bridge is a dense connective tissue connecting muscles and ligaments to the spinal dura mater in the atlanto-occipital interspace. Some researchers believe that the myodural bridge may play a vital physiological role. It is possible, for instance, that the prevention of spinal dura mater infoldings might be involved in regulated cerebrospinal fluid circulation. For instance, it is possible to prevent spinal dura mater infoldings, regulating cerebrospinal circulation. Bats are nocturnal and the only mammals that can perform a genuine and sustained flight, whereas tree shrews are arboreal mammals that often climb to a high altitude of about 10,000 feet. Both animals have lifestyles that are different from other previously studied mammals. The study of these two animals will shed further light on the existence of the myodural bridge in mammals. Gross anatomical dissection was used to observe the connections between the deep muscles of the neck and the dura mater at the level of the atlanto-occipital interspace. The existing structures were analyzed using conventional and special histological staining techniques. The suboccipital regions in bats and tree shrews contained the rectus capitis dorsal major (RCDma), rectus capitis dorsal minor (RCDmi), oblique capitis anterior (OCA), and oblique capitis posterior (OCP). Dense connective tissue connects the RCDmi to the posterior atlanto-occipital membrane (PAOM) and the latter to the spinal dura mater. The myodural bridge in these mammals shares a similar structure to the myodural bridge in humans. Histological analyses confirmed that the connective fibers of the myodural bridge were primarily type I collagen fibers. In this study, it is supplemented by the existence of the myodural bridge in mammals. This further demonstrates that myodural bridge widely exists in the normal anatomy of mammals. This provides morphological support for a comparative anatomical study of the physiological function of the myodural bridge.

El puente miodural es un tejido conjuntivo denso que conecta los músculos y los ligamentos a la duramadre espinal en el espacio atlanto-occipital. Algunos investigadores creen que el puente miodural puede desempeñar un papel fisiológico vital. Es posible, por ejemplo, que la prevención de los pliegues de la duramadre espinal pueda estar involucrada en la circulación regulada del líquido cefalorraquídeo. En esta instancia, es posible prevenir los pliegues de la duramadre espinal, regulando la circulación cerebro espinal. Los murciélagos son animales nocturnos y los únicos mamíferos que pueden realizar un vuelo real y sostenido, mientras que las musarañas arborícolas son mamíferos arbóreos que a menudo ascienden a una gran altura de unos 10 000 pies. Ambos animales tienen estilos de vida diferentes a los de otros mamíferos previamente estudiados. El estudio de estos dos animales ofrecerá más información sobre la existencia del puente miodural en los mamíferos. Se realizó una disección anatómica macroscópica para observar las conexiones entre los músculos profundos del cuello y la duramadre a nivel del espacio atlanto-occipital. Las estructuras existentes se analizaron mediante técnicas de tinción histológica convencionales y especiales. Las regiones suboccipitales en murciélagos y musarañas arbóreas presentaban el músculo recto dorsal mayor de la cabeza (RCDma), el recto dorsal menor de la cabeza (RCDmi), el oblicuo anterior de la cabeza (OCA) y el oblicuo posterior de la cabeza (OCP). El tejido conjuntivo denso conecta el RCDmi con la membrana atlanto- occipital posterior (PAOM) y esta última con la duramadre espinal. El puente miodural en estos mamíferos comparte una estructura similar al puente miodural en humanos. Los análisis histológicos confirmaron que las fibras conectivas del puente miodural son principalmente fibras de colágeno tipo I. Esto demuestra además que el puente miodural existe ampliamente en la anatomía normal de los mamíferos. Esta investigación proporciona apoyo morfológico para un estudio anatómico comparativo de la función fisiológica del puente miodural.

Do politics and administration affect innovation performance? A comparative analysis / ¿La política y la administración afectan el desempeño de la innovación? Un análisis comparativo / A política e a administração afetam o desempenho da inovação? Uma análise comparativa

Abstract The paper's primary goal is to analyze the effects of politics and administrative capacity on countries' innovative performance. The inquiry comparatively examines possible correlations between democracy, political competition, income inequality, bureaucratic capacity, and corruption/transparency with countries' innovation results. The dependent variables are three performance indicators of the Global Innovation Indexes (GII). After presenting the theory and the descriptive data analysis on the research variables, the paper runs multivariate regression models to test the hypotheses. The empirical analysis reinforced that political and administrative dimensions are relevant to understanding the national innovation systems' achievements. However, democracy, bureaucracy quality and corruption/transparency are not influential factors in countries' innovative results as the normative assumptions would suppose. On the contrary, political competition and inequality considerably impact how economies innovate. In conclusion, the paper brought original and intriguing findings that put in perspective the claim that there is a unique path or rule of thumb for innovation growth. Consequently, the inferences provide insights to scholars and stakeholders, public and private, to improve the debates and decisions regarding the priorities for government actions in times of evidence-based policymaking.

Resumen El objetivo principal del documento es analizar los efectos de la política y la capacidad administrativa en el desempeño innovador de los países. La investigación examina comparativamente las posibles correlaciones entre democracia, competencia política, desigualdad de ingresos, capacidad burocrática y corrupción/transparencia con los resultados de innovación de los países. Las variables dependientes son tres indicadores de desempeño de los Índices Globales de Innovación (GII). Después de presentar la teoría y el análisis descriptivo de los datos sobre las variables de investigación, el documento ejecuta modelos de regresión multivariados para probar las hipótesis. El análisis empírico reforzó que las dimensiones política y administrativa son relevantes para comprender los logros de los sistemas nacionales de innovación. Sin embargo, la democracia, la calidad de la burocracia y la corrupción/transparencia no son factores influyentes en los resultados innovadores de los países como lo supondrían los supuestos normativos. Por el contrario, la competencia política y la desigualdad afectan considerablemente la forma en que las economías están innovando. En conclusión, el documento presentó hallazgos originales e interesantes que pusieron en perspectiva la afirmación de que existe un camino único o regla general para el crecimiento de la innovación. En consecuencia, las inferencias brindan información a académicos y partes interesadas, públicas y privadas, para mejorar los debates y las decisiones sobre las prioridades de las acciones gubernamentales en tiempos de formulación de políticas basadas en evidencia.

Resumo O objetivo principal do artigo é analisar os efeitos da política e da capacidade administrativa sobre o desempenho inovador dos países. A pesquisa examina comparativamente possíveis correlações entre democracia, competição política, desigualdade de renda, capacidade burocrática e corrupção/transparência com os resultados de inovação dos países. As variáveis dependentes são três indicadores de desempenho dos Índices de Inovação Global (GII). Após apresentar a teoria e a análise descritiva dos dados das variáveis da pesquisa, o trabalho emprega modelos de regressão multivariada para testar as hipóteses. A análise empírica reforçou que as dimensões política e administrativa são relevantes para entender as realizações dos sistemas nacionais de inovação. No entanto, democracia, qualidade da burocracia e corrupção/transparência não são fatores influentes nas performances inovadoras dos países como supõem os pressupostos normativos.

Transcriptome analysis of Saposhnikovia divaricata and mining of bolting and flowering genes / 中草药·英文版

OBJECTIVE@#Early bolting of Saposhnikovia divaricata has seriously hindered its medicinal value and sustainable development of resources. The molecular mechanism of bolting and flowering of S. divaricata is still unclear and worth of research. In our study, we explored the transcriptome of the genes related to the bolting and flowering of S. divaricata.@*METHODS@#The transcriptome library was constructed, sequenced, assembled and annotated from the bolting and unbolting leaves of S. divaricata by high-throughput sequencing at the bud and flowering stage. Focus on the pathways related to bolting and flowering in plants, and exploring genes. The expression of seven candidate genes was verified by real-time fluorescence quantitative PCR (qRT-PCR).@*RESULTS@#Transcriptome results showed that 249 889 422 high-quality clean reads were obtained. A total of 67 866 unigenes were assembled with an average length of 948.1 bp. Trinity de Novo assembly produced 67 866 unigenes with an average length of 948.1 bp. Among 993 differentially expressed genes, 484 genes were significantly up-regulated and 509 genes were down-regulated in the SdM group. A total of 79 GO terms were significantly enriched for differentially expressed genes. KEGG results showed that 11 154 unigenes were enriched in 89 pathways. And 21 candidate genes related to bolting and flowering of S. divaricata were excavated. The qRT-PCR results showed that expression trends of HDA9, PHYB, AP2, TIR1, Hsp90, CaM, and IAA7 were consistent with transcriptomic sequencing results. In addition, RNA-seq had identified 10 740 transcription factors and classified them into 58 families by their conserved domains. Further studies showed that the transcription factors regulating the flowering of S. divaricata were mainly distributed in the NAC, MYB_related, HB-other, ARF, and AP2 families.@*CONCLUSION@#Based on the results of this study, it was found that the plant hormone signal transduction pathway was one of the decisive factors to control bolting and flowering. Among them, auxin related genes IAA and TIR1 are the key genes in the bolting and flowering process of S. divaricata.

Using transporter to enhance the acid tolerance of Bacillus coagulans DSM1 / 生物工程学报

As the precursor of polylactic acid (PLA), optically pure l-lactic acid production is attracting increasing attention. The accumulation of lactic acid during fermentation inhibits strain growth. Therefore, it is necessary to improve the acid tolerance of lactic acid producers. In this study, comparative transcriptomic analysis was performed to investigate the effects of transporters on lactic acid tolerance of Bacillus coagulans DSM1, which is an l-lactic acid producer. The genes with more than two-fold up-regulation in transcriptional profile were further verified using real-time PCR. The transcriptional levels of RS06895, RS10595, RS10595, RS00500, RS00500, RS10635 and RS10635 were enhanced during lactic acid fermentation. Strain overexpressing RS10595 exhibited a retarded cell growth and low lactic acid production at pH 6.0, but an improved lactic acid production at pH 4.6. This study may facilitate the investigation of the acid tolerance mechanism in B. coagulans DSM1, as well as the construction of efficient lactic acid producers.

Comparative Study of the Distal Transverse Arch of the Hand Between the Dominant and Non-Dominant Hands and By Age and Sex / The Japanese Journal of Rehabilitation Medicine

Introduction：The range of motion (ROM) of the distal transverse arch of the hand has not been established and cleared sufficiently.Purpose：The aim of this study was to clarify the differences in the distal transverse arch of the hand in ROM between the dominant and non-dominant hands and by sex and age.Participants：We enrolled 118 healthy participants aged 20-69 years.Results：The average active and passive ROMs of the distal transverse arch of the hand were 135.4° ± 10.3°/168.9° ± 12.1° on the dominant side and 131.8° ± 9.8°/166.9° ± 13.2° on the non-dominant side. Active and passive ROMs were significantly larger on the dominant side than on the non-dominant side (p＜0.001, p＝0.009). The active or passive ROM of the distal transverse arch of the hand on either side did not differ significantly between men and women. However, the ROM of the ring finger component was significantly larger in women than in men on both sides (p＝0.02～0.003). The active and passive ROMs of the distal transverse arch in both hands were significantly smaller in participants aged over 60 years than in those aged up to 60 years (p＜0.05). Moreover, compared to participants in their 20s, participants in their 30s and 40s showed lower passive ROMs of the dominant hand and little finger component of the transversal arch in both hands (p＜0.05).Discussion：Our results suggested that handedness, sex, and age should be considered when managing the distal transverse arch of the hand.

Risk assessment of clinical trials is of great significance to improve the quality of clinical trials. Through systematic comparative analysis of risk assessment tools for clinical trials in Britain, Germany and France, this paper found that the three countries’ risk assessment tools were consistent in terms of legal system guarantee and assessment process, but there were obvious differences in the basic risk classification and risk grading standards of clinical trials. Based on the experience of Britain, France and Germany, this paper proposed to improve the relevant regulations and documents of clinical trial risk management in China from the perspective of Chinese national conditions, further explore the factors affecting clinical trial risk, and develop and design clinical trial risk assessment tools with different discipline characteristics according to the specialties of the discipline to improve the quality and level of clinical trials.

Efficacy and safety of endoscopic retrograde cholangiopancreatography during pregnancy and puerperium： A comparative analysis / 临床肝胆病杂志

ObjectiveTo investigate the efficacy and safety of endoscopic retrograde cholangiopancreatography （ERCP） during pregnancy and puerperium through a comparative analysis. MethodsA retrospective analysis was performed for the clinical data of 22 patients in pregnancy and 39 patients in puerperium who received ERCP in Digestive Endoscopy Center of The First Affiliated Hospital of Nanchang University from January 2007 to August 2022. The two groups of patients were compared in terms of baseline data， diagnosis during ERCP， interventions， laboratory results before and after ERCP， post-ERCP complications， and delivery and fetal outcomes. The independent-samples t test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsThere were no significant differences between the patients in pregnancy and those in puerperium in all baseline data （all P>0.05） except the rate of CT examination （22.73% vs 58.97%， χ2=7.44， P=0.006）. During the ERCP procedure， compared with the patients in puerperium， the patients in pregnancy had a significantly lower proportion of the patients who underwent biliary stone extraction or endoscopic papillary balloon dilation （χ2=4.007 and 4.315， both P<0.05） and a significantly higher proportion of the patients who did not receive X-ray fluoroscopy （χ2=12.103， P=0.001）. After ERCP， both groups had significant improvements in white blood cell count， total bilirubin， direct bilirubin， alanine aminotransferase， and aspartate aminotransferase （all P<0.05）. The overall incidence rate of post-ERCP complications was 7.04% （5/71） for all patients， with post-ERCP biliary infection as the most common complication （3/71，4.23%）， and there was no significant difference in the incidence rate of post-ERCP complications between the two groups （P>0.05）. As for delivery and fetal outcomes， compared with the patients in puerperium， the patients in pregnancy had a significantly higher proportion of patients with early termination of pregnancy （50.00% vs 0，χ2=20.528， P<0.001） and a significantly lower proportion of patients with cesarean section （36.36% vs 76.92%， χ2=4.756， P=0.029）. There were no significant differences in the incidence rates of adverse events such as abnormal fetal development and stillbirth between the two groups （P>0.05）. ConclusionWith strict control of ERCP indications and timing， ERCP is effective and relatively safe in both pregnancy and puerperium and has a comparable incidence rate of post-ERCP complications to that in the general population， with relatively good delivery and fetal outcomes.

A comparative study of the original articles about the springs in the explanatory literature on the Ma la ya'i mystery / Монголын Анагаах Ухаан

Introduction@#There is a sutra named “Detail explanatory of Ma la ya'i mystery and the giver everything wanted” (Ma la ya'i dka' 'grel 'dod pa 'jo ba) written by Mi'i nyi ma mthong ba don ldan, a Tibetan, which is considered as one of the undisputed ancient articles of Indian and Tibetan Medicines and to which Mongolian medical researchers in Mongolia and in Inner Mongolia, China haven't paid attention yet, so it is still not included in the scope of medical research work until now. </br>The sutra has an advantage that the place where the spring comes out is written in detail. Therefore, we now should thoroughly analyze the source place and features of the springs in order to convey a clear orderly understanding to future scholars by summarizing the research aligning it with traditional medical theory, and schematically mapping. @*Goal@#To make clearer the scholars' views of the four mountains included in the book “Rsta b’ai rgyud” and its theoretical and other concepts, as well as to analyze and conclude the interrelationships and features of springs in Ma la ya'i mountain. @*Materials and Methods@#In this research, I have studied the theory of Four mountains included in the book “Rsta b’ai rgyud” using the analyzing methods for original and source documents and summarized by the method of analysis and synthesis, as well as chosen the literature named “Detail explanation of Ma la ya'i mystery and the giver everything wanted” by sampling method and shown making sketch for the interrelations and features of springs by Hermeneutic method. @*Results@#As descried by a person named Gyutog yontan mgonpo (Gyutog yontan mgonpo) in terms of Foreign, Domestic and Secret Medicine Palaces, and according to the relevant sutras and mantras that said about them, the springs have the ability to heal diseases with the participation of earth directions, flora and fauna around the mountain and other factors. The sketch was clearly shown for the springs. @*Conclusion@#I believe that the debates about the Medicine Palace are highly dependent on the chronology in which the researchers lived and their own traditional ways. Currently, the five explanatory manuscripts written through XII - XX centuries about Medicine Palaces and Springs in Ma la ya'i Mountain have been found, among which, specially, the section written about the springs in the sutra named “Detail explanatory of Ma la ya'i mystery and the giver everything wanted” is a big thick book that was made at the level of "Great Explanation" in terms of its content. Therefore, I consider that this literature has become a new cognitive valuables added to the modern research resource because the knowledge of springs was presented greatly in depth and detail in this paper work.

Characteristics of the chloroplast genome of Dracaena marginata and phylogenetic analysis / 生物工程学报

Dracaena marginata is a widely cultivated horticultural plant in the world, which has high ornamental and medicinal value. In this study, the whole genome of leaves from D. marginata was sequenced by Illumina HiSeq 4000 platform. The chloroplast genome were assembled for functional annotation, sequence characteristics and phylogenetic analysis. The results showed that the chloroplast genome of D. marginata composed of four regions with a size of 154 926 bp, which was the smallest chloroplast genome reported for Dracaena species to date. A total of 132 genes were identified, including 86 coding genes, 38 tRNA genes and 8 rRNA genes. Codon bias analysis found that the codon usage bias was weak and there was a bias for using A/U base endings. 46 simple sequence repeat and 54 repeats loci were detected in the chloroplast genome, with the maximum detection rate in the large single copy region and inverted repeat region, respectively. The inverted repeats boundaries of D. marginata and Dracaena were highly conserved, whereas gene location differences occurred. Phylogenetic analysis revealed that D. serrulata and D. cinnabari form a monophyletic clade, which was the closest relationship and conformed to the morphological classification characteristics. The analysis of the chloroplast genome of D. marginata provides important data basis for species identification, genetic diversity and chloroplast genome engineering of Dracaena.

Genetic and Phenotypic Variation of Campylobacter jejuni NCTC11168 Caused by flhA Mutation during Laboratory Passage / 生物医学与环境科学（英文）

OBJECTIVE@#Campylobacter jejuni NCTC11168 is commonly used as a standard strain for flagellar biosynthesis research. In this report, two distinguished phenotypic isolates (CJ1Z, flhA mutant strain, lawn; CJ2S, flhA complemented strain, normal colony) appeared during laboratory passages for NCTC11168.@*METHODS@#Phenotypic assessments, including motility plates, transmission electron microscopy, biofilm formation assay, autoagglutination assay, and genome re-sequencing for these two isolates (CJ1Z, flhA mutant strain; CJ2S, flhA complemented strain) were carried out in this study.@*RESULTS@#Transmission electron microscopy revealed that the flagellum was lost in CJ1Z. Phenotypic assessments and genome sequencing of the two isolates were performed in this study. The capacity for biofilm formation, colony auto-agglutination, and isolate motility was reduced in the mutant CJ1Z. Comparative genomic analysis indicated a unique native nucleotide insertion in flhA (nt, 2154) that caused the I719Y and I720Y mutations and early truncation in flhA.@*CONCLUSION@#FlhA has been found to influence the expression of flagella in C. jejuni. To the best of our knowledge, this is the first study to describe the function of the C-terminal of this protein.
