Résumé

Abstract Objectives: To analyze bone mineral content (BMC) and area bone mineral density (aBMD) accrual in adolescent male footballers who started their first football season. Methods: 17 athletes (14.8 ± 0.4 years) were monitored across 15 weeks of football training. Participants were evaluated for somatic maturation (HPHV), BMC, and aBMD at three time points: before (M1) and after (M2) a preparatory phase, and at the end of the competitive phase (M3). BMC and aBMD were measured using DXA scans. Participants were divided into groups according to maturation status (circa-PHV and post-PHV), and the amount of accumulated training load (median split). Results: A significant effect (12.1 g/week, standard error (SE) = 2.6 g/week) was observed for lower limbs BMC across the three time points. There were no significant effects of time for upper limbs BMC. There was a significant effect of time for total body aBMD (0.007, SE = 0.003 g/cm2/week) across the three time points. Adolescents at post-PHV had a significant 245.6 g (SE = 56.1 g) higher BMC compared to adolescents at circa-PHV. No significant effects were observed for the accumulated training load. Conclusion: Systematic football training, even during the growth spurt, has a positive impact on adolescent bone markers despite the accumulated training load and maturation.

Résumé

SUMMARY: Diabetes is a form of endocrine disease. Dual-energy X-ray Absorptiometry (DXA) provides a detailed view of the body composition to find out what makes people with diabetes different from those with other diseases. We scanned 371 patients with DXA to analyze their body composition parameters. Three hundreds and seventy one patients (178 women/193 men), who with different diseases, with a mean±SD Body Mass Index (BMI) of 25.32±8.3 kg/m2 were included. The body composition of 371 patients was assessed. Bone Mineral Density (BMD), Fat Weight, Lean Weight, waist-to-hip ratio, Lean Mass Index (LMI), Fat Mass Index (FMI), the relationship between Fat percentage and BMI were analyzed. The 371 patients included 156 diabetics and 215 non-diabetics. Non-diabetic patients also included 5 obesity patients, 9 patients with fatty liver, 39 patients with hypertension, 22 patients with hyperlipidemia, 18 patients with cardiovascular disease, 11 patients with chest and lung disease, 4 patients with chronic disease, 14 patients with brain disease and 93 patients with other diseases. Among 156 diabetic patients, 129 had VAT > 100 cm2 and 27 had VAT ≤100 cm2. The lean weight (LW) of male diabetic patients was significantly higher than that of female diabetic patients. The fat weight (FW) of female patients with diabetes was significantly higher than that of male patients. The waist-hip ratio (WHR) was 1.37 ± 0.25 in male diabetic patients and 1.18 ± 0.21 in female diabetic patients. Among the 215 non-diabetic patients, the obese and fatty liver patients, which the weight (WT) (obesity: 83.87 ± 8.34 kg fat liver: 85.64±28.60 kg), FW (obesity: 28.56 ± 4.18 kg fat liver: 28.61 ± 10.79 kg), LW (obesity: 52.62 ± 9.64 kg fat liver: 54.29±17.58 kg), BMI (obesity: 28.76 ± 1.88 kg/m2 fat liver: 29.10 ± 5.95 kg/m2), was much higher than other patients. Diabetes patients had less fat mass than non- diabetic patients; the difference was around 2 kg. BMI is also a modest number. BMD doesn't differ all that much. Non-diabetic patients with fatty liver obesity and cardiovascular disease had higher fat mass and BMI than patients with other illnesses. Body composition can provide precise information on the makeup of different body areas, but further in-depth exams are required to ascertain the body's endocrine profile.


La diabetes es una enfermedad endocrina. La absorciometría de rayos X de energía dual (DXA) proporciona una vista detallada de la composición corporal para descubrir qué diferencia a las personas con diabetes de aquellas con otras enfermedades. Escaneamos a 371 pacientes con DXA para analizar sus parámetros de composición corporal. Se incluyeron 371 pacientes (178 mujeres/193 hombres), con diferentes enfermedades, con un Índice de Masa Corporal (IMC) medio ± DE de 25,32 ± 8,3 kg/m2. Se evaluó la composición corporal de 371 pacientes. Se analizaron la densidad mineral ósea (DMO), el peso graso, el peso magro, la relación cintura-cadera, el índice de masa magra (LMI), el índice de masa grasa (FMI), y la relación entre el porcentaje de grasa y el IMC. De los 371 pacientes 156 eran diabéticos y 215 no diabéticos. Los pacientes no diabéticos también incluyeron 5 con obesidad, 9 con hígado graso, 39 con hipertensión, 22 con hiperlipidemia, 18 con enfermedad cardiovascular, 11 con enfermedad torácica y pulmonar, 4 con enfermedad crónica, 14 con enfermedad cerebral y 93 pacientes con otras enfermedades. Entre los 156 pacientes diabéticos, 129 tenían un IVA > 100 cm2 y 27 tenían un IVA ≤100 cm2. El peso magro (PV) de los hombres diabéticos fue significativamente mayor que el de las mujeres diabéticas. El peso graso (FW) de las mujeres diabéticas fue significativamente mayor que el de los hombres diabéticos. El índice cintura-cadera (ICC) fue de 1,37 ± 0,25 en hombres diabéticos y de 1,18 ± 0,21 en mujeres diabéticas. Entre los 215 pacientes no diabéticos, los pacientes obesos y con hígado graso, cuyo peso (WT) (obesidad: 83,87 ± 8,34 kg hígado graso: 85,64 ± 28,60 kg), FW (obesidad: 28,56 ± 4,18 kg hígado graso: 28,61 ± 10,79 kg), PV (obesidad: 52,62 ± 9,64 kg, hígado graso: 54,29 ± 17,58 kg), IMC (obesidad: 28,76 ± 1,88 kg/m2, hígado graso: 29,10 ± 5,95 kg/m2), fue mucho mayor que otros pacientes. Los pacientes diabéticos tenían menos masa grasa que los pacientes no diabéticos; la diferencia fue de alrededor de 2 kg. La DMO no difiere mucho. Los pacientes no diabéticos con obesidad debido al hígado graso y enfermedades cardiovasculares tenían mayor masa grasa e IMC que los pacientes con otras enfermedades. La composición corporal puede proporcionar información precisa sobre la composición de diferentes áreas del cuerpo, pero se requieren exámenes más profundos para determinar el perfil endocrino del cuerpo.

Résumé

SUMMARY: The identification of children and adolescents who are at risk of sarcopenic obesity development often requires specialized equipment and expensive test procedures. Therefore, the establishment of cheaper and faster methods would be greatly useful, especially if they could be applied in the field. The study's objective was to establish if identification of female adolescents who suffer the risk of developing sarcopenic obesity can be obtained through the standing-long-jump test application. To achieve the research objectives, various anthropometric and body composition measurements were performed and lower limb explosive strength was assessed using the standing long jump fitness test. The research was conducted on a sample of 535 female respondents randomly selected from 9 elementary schools in the Skopje region of the Republic of North Macedonia. The respondents were divided into quintiles according to BMI z-scores, and the arithmetic means and SD about muscle-to-fat ratio were calculated for each quintile. The cutoff was determined based on the mean and standard deviation of the muscle-to-fat ratio for the 3rd quintile of BMI and the percentage of respondents with sarcopenic obesity was examined. The optimal cut-off value of the long jump fitness test results for predicting sarcopenic obesity in an adolescent girl showed that the area under the ROC curve was 0.781 (95 % CI 0.743-0.815). The standing-long-jump test values, on grounds of odds ratio (OR 95 % CI) about the girls at risk of sarcopenic obesity development, which was identified on muscle-to-fat ratio base, were 8.76 (4.39 - 17.54, p 0.001). It can be used to predict sarcopenic obesity presence in female adolescents, which can be vital in case of health intervention.


La identificación de niños y adolescentes que corren riesgo de desarrollar obesidad sarcopénica a menudo requiere equipos especializados y procedimientos de pruebas costosos. Por lo tanto, el establecimiento de métodos más baratos y rápidos sería de gran utilidad, especialmente si pudieran aplicarse en el campo. El objetivo del estudio fue establecer si la identificación de mujeres adolescentes que sufren riesgo de desarrollar obesidad sarcopénica se puede obtener mediante la aplicación de la prueba de salto de longitud de pie. Para lograr los objetivos de la investigación, se realizaron diversas mediciones antropométricas y de composición corporal y se evaluó la fuerza explosiva de los miembros inferiores mediante la prueba de aptitud de salto de longitud de pie. La investigación se realizó con una muestra de 535 mujeres encuestadas seleccionadas al azar de 9 escuelas primarias de la región de Skopje, en la República de Macedonia del Norte. Los encuestados se dividieron en quintiles según las puntuaciones z del IMC, y se calcularon las medias aritméticas y la DE sobre la relación músculo-grasa para cada quintil. El límite se determinó en función de la media y la desviación estándar de la relación músculo-grasa para el tercer quintil del IMC y se examinó el porcentaje de encuestados con obesidad sarcopénica. El valor de corte óptimo de los resultados de la prueba de condición física de salto de longitud para predecir la obesidad sarcopénica en una adolescente mostró que el área bajo la curva ROC fue 0,781 (IC del 95 %: 0,743-0,815). Los valores de la prueba de salto de longitud de pie, sobre la base del odds ratio (OR IC del 95 %) sobre las niñas en riesgo de desarrollar obesidad sarcopénica, que se identificó sobre la base del ratio músculo-grasa, fueron 8,76 (4,39 - 17,54, p. 0,001). Puede utilizarse para predecir la presencia de obesidad sarcopénica en adolescentes, lo que puede ser vital en caso de intervención sanitaria.

Este estudio transversal se desarrolló con una muestra de 50 estudiantes de odontología de 19 a 34 años de edad, 58% mujeres y 42% hombres. Se recogieron muestras de saliva entera sin estimular en la mañana (6:30-7:30 a.m.) y en la tarde (4:00-6:00 p.m.). Los valores de AAs se determinaron mediante método cinético y se expresaron como media ± desviación estándar. Se realizaron análisis descriptivo de datos, prueba de chi-cuadrado, prueba de correlación de Pearson y prueba t de muestras pareadas. Resultados. El IMC promedio fue de 23,85 ± 3,30 kg/m2, 66% de los participantes presentó peso normal (IMC ≤ 25 kg/m2). Los niveles de AAs por la tarde (282,74 ± 59,60 U/ml) fueron mayores a los de la mañana (190,84 ± 61,80 U/ml), (t = 16,51, p < 0,0001). Los hombres mostraron niveles de AAs más altos que las mujeres (p < 0,0001). La edad no mostró asociación con los niveles de AAs. Los valores de IMC y AAs presentaron una correlación positiva (AM: r = 0,35, p = 0,0121; PM: r = 0,40, p = 0,0036). Conclusión. El nivel de actividad de AAs se puede utilizar como posible biomarcador para evaluar el IMC en relación con el sexo, especialmente en los adultos jóvenes.


Objective. To determine the presence and direction of the relationship between salivary alpha-amylase (sAA), age, sex, and body mass index (BMI) in young adults. Methods. This cross-sectional study was developed with a sample of 50 dental students from 19 to 34 years of age, 58% women and 42% men. Unstimulated whole saliva samples were collected in the morning (6:30-7:30 a.m.) and in the afternoon (4:00-6:00 p.m.). sAA values were determined by the kinetic method and expressed as mean ± standard deviation. Descriptive data analysis, chi-square test, Pearson correlation test, and paired samples t-test were made. Results. Mean BMI was 23.85 ± 3.30 kg/m2, 66% of the participants presented normal weight (BMI ≤ 25 kg/m2). Levels of sAA in the afternoon (282.74 ± 59.60 U/ml) were higher than those in the morning (190.84 ± 61.80 U/ml), (t = 16.51, p < 0, 0001). Men showed higher levels of sAA than women (p < 0.0001). Age did not show an association with sAA levels. BMI and AAs values presented a positive correlation (AM: r = 0,35, p = 0,0121; PM: r = 0,40, p = 0,0036). Conclusions. AAs activity level can be used as a potential biomarker to assess BMI in relation to sex, especially in young adults.

Résumé

Introducción. El aneurisma de la aorta abdominal (AAA) es la dilatación de la aorta abdominal mayor de 1,5 veces el diámetro esperado. Su prevalencia es variable, con tasas reportadas de hasta el 12,5 %. Se considera como causa de muerte de más de 10.000 personas al año en los Estados Unidos. El objetivo de esta revisión de la literatura fue describir los factores de riesgo y las herramientas de tamizaje de AAA. Métodos. Se realizó una búsqueda de la literatura utilizando dos ecuaciones en bases de datos electrónicas, empleando términos seleccionados de "Medical Subject Heading" (MeSH) y "Descriptores en Ciencias de la Salud" (DeCS). Se evaluó la calidad de los estudios con la herramienta STROBE (Strengthening the Reporting of Observational Studies in Epidemiology). Resultados. Se recolectaron 40 artículos y a partir de ellos se construyó el texto de revisión, identificando en estos, los factores de riesgo asociados al desarrollo de AAA, tales como sexo masculino, tabaquismo, hipertensión arterial, antecedente familiar y obesidad, entre otros. La diabetes mellitus parece actuar como factor protector. Dentro de los instrumentos de tamizaje, el ultrasonido abdominal es uno de los más usados. Conclusión. El AAA es una patología multifactorial. En la actualidad la ultrasonografía de aorta es el método de elección para el tamizaje, permitiendo la detección precoz. El tamizaje de AAA con métodos no invasivos, como el ultrasonido, es útil sobre todo en zonas con prevalencia alta de la patología y en pacientes con determinados factores de riesgo.


Introduction. Abdominal aortic aneurysm (AAA) is a dilation of the abdominal aorta greater than 1.5 times the expected diameter. Its prevalence is variable, with reported rates of up to 12.5%. It is considered the cause of death of more than 10,000 people a year in the United States. The objective of this literature review was to describe risk factors and screening tools for AAA. Methods. A literature search was conducted using two equations in electronic databases, using terms selected from "Medical Subject Heading" (MeSH) and "Descriptors in Health Sciences" (DeCS). The quality of the studies was evaluated with the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) tool. Results. Forty articles were collected and from them the review text was constructed, identifying the risk factors associated with the development of AAA, such as male sex, smoking, high blood pressure, family history and obesity, among others. Diabetes mellitus seems to act as a protective factor. Among the screening instruments, abdominal ultrasound is one of the most used. Conclusion. AAA is a multifactorial pathology. Currently, aortic ultrasonography is the method of choice for screening, allowing early detection. Screening for AAA with non-invasive methods, such as ultrasound, is useful especially in areas with a high prevalence of this pathology and in patients with certain risk factors.

Résumé

SUMMARY: In our study, we aimed to reveal the relationship between the anatomical localizations measured and the Body Mass Index (BMI) in patients scheduled for upper gastrointestinal endoscopy. In this study, anatomical localizations of the hiatal clamp and oesophagogastric junction in 189 female and 137 male patients who applied to the hospital with different gastrointestinal system complaints and underwent esophagogastroduodenoscopy (EGD) were investigated depending on BMI. In addition, the data were compared with the patients' complaints before EGD and the diagnoses they received after EGD. SPSS Statistics 22 (IBM Corp. Turkey) program was used for statistical analysis and p0.05). On the other hand, it was determined that the hiatal clamp distance and the distance of the oesophagogastric junction increased as the height and weight increased (p38. As a result of the study, it can be said that BMI values, hiatal clamp distance and oesophagogastric junction localizations may change in relation to height and weight.


En este estudio, buscamos revelar la relación entre las localizaciones anatómicas y el Índice de Masa Corporal (IMC) en pacientes programados para endoscopía digestiva alta. Se investigaron las localizaciones anatómicas de la pinza hiatal y la unión esofagogástrica en 189 mujeres y 137 hombres que acudieron al hospital con diferentes problemas del sistema gastrointestinal los cuales fueron sometetidos a una esofagogastro- duodenoscopia (EGD) dependiendo del IMC. Además, los datos se compararon con las quejas de los pacientes antes de la EGD y los diagnósticos que recibieron después de la EGD. Se utilizó el programa SPSS Statistics 22 (IBM Corp. Turquía) para el análisis estadístico y el valor de p0,05). Por otro lado, se determinó que la distancia de la pinza hiatal y la unión esofagogástrica aumentaba con la altura y el peso corporal (p38. Como resultado del estudio, se puede decir que los valores de IMC, la distancia de pinzamiento hiatal y las localizaciones de la unión esofagogástrica pueden cambiar en relación con la altura y el peso.

Résumé

Expanding uterine masses can be the cause of pregnancy loss and add technical difficulties to uterus evacuation due to the intense anatomical distortion of the endocervical canal and uterine cavity. The literature is scarce in the peculiarities of the management of missed abortions in uterus with important distorted anatomies. We report a case of a primigravida patient who presented a rapid and expressive increase of abdominal volume due to a giant uterine mass, evolving to miscarriage. Ultrasound can be a useful tool, allowing visualization of the endocervical path and uterine cavity, helping to perform uterine evacuation in the presence of anatomical distortion without compromising the reproductive future. To the best of our knowledge, no such case has been previously reported.

Résumé

Background: Peripheral neuropathy is a serious complication of diabetes, which has socioeconomic consequences as well as a reduced quality of life. Early neuropathic process recognition and management could alter its course and considerably reduce the associated morbidity and mortality. This study determines the effect of long-term glycemic control on diabetic peripheral neuropathy in people with type 2 diabetes (T2DM). Methods: A hospital-based study was carried out at the National Centre of Neurosciences and Ibrahim Malik Hospital in Khartoum. All individuals who were older than 18 years and have had T2DM for less than 10 years were recruited. Using accepted techniques, the BMI, HbA1c level, and nerve conduction studies (NCS) were measured. Data were analyzed using the Statistical Package for Social Sciences (SPSS), version 25.0 software. P-value ≤ 0.05 was considered significant. Results: Of the 95 patients with T2DM, 52 were male patients. Our findings showed that as the duration of diabetes increased, the sensory velocity reduced from 64.07 ± 3.22 to 54.00 ± 5.34 and the motor nerve from 63.39 ± 2.38 to 53.87 ± 2.08 (P = 0.05, P = 0.003, respectively). Additionally, with increased duration of diabetes, a significant decrease was seen in both motor nerve amplitude from 8.79 ± 3.11 to 6.94 ± 1.84 (P = 0.05) and sensory nerve amplitude from 25.71 ± 5.70 to 19.51 ± 6.51 (P = 0.003). Also, all parameters of NCS (velocity and amplitude) decreased when Hb A1c was >6 ­ sensory velocity from 63.96 ± 2.36 to 55.49 ± 2.43 (P = 0.03) and motor velocity from 63.00 ± 2.59 to 51.44 ± 1.66 (P = 0.02). And sensory amplitude decreased from 26.91 ± 1.26 to 20.85 ± 2.1 (P = 0.05), while motor amplitude decreased from 6.88 ± 3.55 to 6.61 ± 3.29 (P = 0.05). Additionally, there is a substantial (P = 0.05) correlation between sensory and motor amplitudes and the BMI. Conclusion: High BMI and poorly controlled (high HbA1c) long-term diabetes had a negative impact on all nerve conduction study parameters

Résumé

italic>Schisandra chinensis is a traditional Chinese medicine with the functions of reinforcing deficiency, strengthening, and inducing astringency, appliable to treat the chronic cough and deficiency in breath, palpitation, and insomnia, etc. A hybrid mass spectrometry scanning strategy (high-definition data-independent/data-dependent acquisition, HDDIDDA), enabling the ion mobility separation and alternating data-independent acquisition/data-dependent acquisition, was established, which, in combination with in-house library-driven automatic peak annotation workflows facilitated by the UNIFI software, was utilized to systematically characterize the multi-classes of chemical components from S. chinensis. The use of an HSS T3 column (100 mm × 2.1 mm, 1.8 μm), 0.1% formic acid in H2O-acetonitrile as the mobile phase running at the flow rate of 0.3 mL·min-1, and column temperature at 35 ℃, could enable good separation of the S. chinensis components within 42 min. HDDIDDA scan in both the positive and negative ion modes was employed for data acquisition. Based on the automatic peak annotation, reference standards comparison, MS2 data interpretation, and literature analysis, we were able to identify or tentatively characterize 105 compounds in the S. chinensis decoction, involving 56 terpenoids, 42 lignans, five glycosides, one organic acid, and one flavonoid. HDDIDDA scanning can improve the coverage of data acquisition and improve the accuracy of identification, while CCS prediction analysis provides the possibility to distinguish isomers by the ion mobility technology. The results provide reference for the intelligent material basis research of TCM.

ObjectiveThrough the correlation analysis between intestinal absorption profile and inhibition of macrophage foaming, the pharmacodynamic components of Zhuriheng dripping pills(ZRH) were explored to provide a basis for establishing its quality standard. MethodIntestinal absorption fluids with 0, 5, 10, 15, 20 times clinical equivalent doses were prepared by a rat everted gut sac(EGS), and the oxidized low density lipoprotein(ox-LDL)-induced RAW264.7 macrophage foaming model was used to investigate the effect of intestinal absorption fluid with different doses on the accumulation of lipids in RAW264.7 cells by oil red O staining and cholesterol content determination, and to screen for the optimal dose. Ultra performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry(UPLC-Q-Exactive Orbitrap MS) was used to analyze and identify intestinal absorption fractions of ZRH intestinal absorption fluids, and partial least squares-discriminant analysis(PLS-DA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were performed on different doses of ZRH intestinal absorption fluids using SIMCA 13.0 with peak area as the independent variable and the pharmacodynamic indicators as the dependent variables to screen the compounds with variable importance in the projection(VIP) value>1.0 as contributing components, and Pearson correlation analysis was used to determine the spectral effect relationship, determined the compounds and positive correlation with pharmacodynamic were as active ingredients. Molecular docking was used to verify the binding energy of peroxisome proliferator-activated receptor α(PPARα), PPARγ, PPARβ, human retinoid X receptor α(RXRA) and nuclear transcription factor-κB(NF-κB) with the active ingredients in ZRH intestinal absorption fluids. Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) was performed to detect the mRNA levels of PPARγ, scavenger receptor A1(SRA1) and adenosine triphosphate-binding cassette transporter A1(ABCA1) in RAW264.7 cells, Westen blot was used to detect the expression level of PPARγ protein in RAW264.7 cells, and enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of interleukin(IL)-1β and NF-κB in RAW264.7 cells. ResultAccording to the results of oil red O staining and cholesterol content determination, the ZRH intestinal absorption fluids could significantly reduce macrophage foaming, and intestinal absorption fluids with 15, 20 times clinical equivalent doses had the best effect, the 15-fold ZRH intestinal absorption fluid was finally determined as the study subject. Spectral effect relationship showed that 52 corresponding peaks in the ZRH-containing intestinal fluid were positively correlated with the efficacy, including organic acids, phenylpropanoids, iridoids, flavonoids, bile acids, coumarins and chromones. Target validation results showed that 86.9%-96.2% of the total components processed good binding activities with the key targets of PPARα, PPARγ, PPARβ, RXRA and NF-κB, and the docking energy values were all less than -6.0 kcal·mol-1(1 cal≈4.19 J). The results of validation showed that, compared with the normal group, the model group showed a significant increase in the levels of SRA1 and PPARγ mRNA expression, a significant decrease in ABCA1 mRNA expression, a significant increase in the level of PPARγ protein expression, and a significant increase in the levels of IL-1β and NF-κB(P<0.01), compared with the model group, the 15-fold intestinal absorption fluid group showed a significant decrease in the levels of SRA1 and PPARγ mRNA expression(P<0.05, P<0.01), ABCA1 mRNA expression level was significantly up-regulated, the levels of IL-1β and NF-κB were significantly reduced(P<0.01), and PPARγ protein expression level was significantly reduced(P<0.05). ConclusionThis study identifies 52 components and their metabolites in ZRH intestinal absorption fluid that are positively correlated with the inhibition of macrophage foaming, which may be related to the regulation of the PPARs pathway in cells and the reduction of the levels of inflammatory factors, and can provide a reference for the quality control and clinical application of ZRH.

Résumé

ObjectiveTo study the changing characteristics of secondary metabolic compounds accumulated in Dendrobium nobile stems at different growth years, a simulated wild stone plant, in order to provide a theoretical basis for rational planning of the harvesting period of D. nobile. MethodUltra-high performance liquid chromatography-mass spectrometry(UPLC-MS/MS) was used to detect and analyze the secondary metabolites in the stems of 1-year-old, 2-year-old, and 3-year-old D. nobile. The mass spectrometry data were processed using Analyst 1.6.3 software, and all samples were subjected to principal component analysis(PCA), cluster heat map analysis, partial least squares-discriminant analysis(PLS-DA), and differential secondary metabolites were screened based on variable importance in projection(VIP) values>1, fold change(FC)≥2 and FC≤0.5. Then differential secondary metabolites were identified based on relative molecular weight, fragmentation ions and mass spectrometry database, and enriched pathways were identified based on the Kyoto Encyclopedia of Genes and Genomes(KEGG) database. ResultA total of 1 317 secondary metabolites were identified in the stems of D. nobile at three growth stages, with flavonoids, phenolic acids, alkaloids and terpenoids accounting for 76.55% of the total. Compared with the 1-year-old stems of D. nobile, 289 differential secondary metabolites were identified in the 2-year-old stems, of which 255 were up-regulated and 34 were down-regulated, 682 differential secondary metabolites were identified in the 3-year-old stems, of which 502 were up-regulated and 180 were down-regulated. Compared to the 2-year-old stems, the 3-year-old stems had 602 differential secondary metabolites, with 405 up-regulated and 197 down-regulated. As the growth stage of D. nobile increased, the top 10 up-regulated differential metabolites mainly included flavonoids, phenolic acids, phenylpropanoids and terpenoids, such as kaempferol derivatives, asperulosidic acid, apigenin derivatives, chrysoeriol derivatives, isorhamnetin derivatives, taxifolin derivatives, quercetin derivatives. KEGG enrichment analysis showed significant enrichment of secondary metabolites in the flavonoid biosynthesis, flavone, and flavonol biosynthesis, secondary metabolite biosynthesis, and phenylpropanoid biosynthesis pathways with the increase of growth years. ConclusionWith the increase of the growth years, the levels of secondary metabolites such as flavonoids, phenolic acids, phenylpropanoids and terpenoids in the wild-grown D. nobile have been significantly enhanced. In practical production, grading based on different growth years can be carried out to improve the medicinal and economic values of D. nobile.

Résumé

ObjectiveTo evaluate the effect of women's body mass index (BMI) on pregnancy outcomes of ovulation induction intrauterine insemination (OI-IUI) in patients with unexplained primary infertility. MethodsThe study included 764 OI-IUI cycles from January 2016 to December 2022 in reproductive center of Sun Yat-sen Memorial Hospital. According to BMI,patients were divided into three groups:low BMI (BMI<18.5 kg/m2), normal BMI (18.5 kg/m2 ≤BMI<23.0 kg/m2), and high BMI (BMI≥23.0 kg/m2). Comparison of clinical data and pregnancy outcomes was performed between the groups. Logistic regression was used to analyze the association between BMI and live birth rate. ResultsFrom the low BMI group to the high BMI group, the HCG positive rate (7.08%,9.74%, 13.19%), clinical pregnancy rate(5.51%, 7.91%, 13.19%), and live birth rate (4.72%, 6.90%, 12.50%) increased. Among them, the live birth rate of the high BMI group was significantly higher than that of the low BMI group and the normal BMI group, with a statistically significant difference (P=0.034). While the early miscarriage rate (14.28%, 10.26%, 5.26%) decreased from the low BMI group to the high BMI group. The binary logistic regression analysis revealed that BMI was an independent factor in live birth, and high BMI resulted in a better live birth rate than low BMI (OR=3.15,95%CI=1.191-8.329,P=0.021). ConclusionLow BMI is associated with poor OI-IUI outcomes in patients with unexplained primary infertility. These patients are encouraged to gain weight in a healthy manner.

Résumé

AIM: To investigate the clinical features of acute exacerbation chronic obstructive pulmonary disease (AECOPD) of complicated with type 2 diabetes mellitus (T2DM), and analyze the related clinical features and risk factors. METHODS: This was a single-center cross-sectional study. From March 2020 to January 2023, 479 hospitalized patients with AECOPD in the department of respiratory and critical care medicine, Suining Central Hospital were included. There were 215 patients in AECOPD group and 60 patients in AECOPD with T2DM group. The collected variables included demographic data, complications, blood routine, infection index, random blood glucose, blood gas analysis and lung function. The adoption rate and constituent ratio of the basic description classification data were expressed as mean standard deviation for the normal distribution measurement data and median interquartile range for the skew distribution measurement data. T-test was used for normal distribution and non - parameter test was used for non-normal distribution. The categorical variables were tested by chi-square test. Rank sum test was used for rank variable data. Binary logistic regression model was used to investigate the independent factors associated with T2DM in patients with AECOPD. Finally, the results of logistic regression were verified and visualized by nomogram, validation curve, ROC curve and DCA curve. P0.05). The results of logistic regression were verified and visualized by Nomogram and its-associated ccurves. The MAE and AUC curves were 0.021 and 0.847 respectively, indicating that the model had good prediction consistency and accuracy. The DCA curve showed that Nomogram's risk threshold ranged from 0.01 to 0.99, suggesting that nomogram's model had better clinical predictive value. CONCLUSION: Our results showed that increased BMI, PaCO2 and random glucose, decreased blood lymphocyte, and atrial fibrillation is an independent clinical feature of AECOPD with T2DM. These results suggest that the immune function of patients with AECOPD and T2DM are more severely impaired and more likely to be accompanied by atrial fibrillation, which is a potential cause of poor prognosis in these patients. Meanwhile, this conclusion needs to be further verified in multicenter study with large sample size.

Résumé

@#Detection of an adnexal mass during pregnancy has increased during the last decade due to liberal use of sonographic examination during the first trimester. While most are benign or physiologic, the probability of a malignant tumor should always be considered. Deciduosis, a phenomenon related to pregnancy, refers to the presence of decidua outside the uterine cavity, most commonly seen within the pelvis. It is a benign condition, which usually regresses during the postpartum period. However, during pregnancy, this ectopic decidua may enlarge and mimic malignancy.

Résumé

ObjectiveTo investigate the effects of Aconiti Coreani Radix and Typhonii Rhizoma on the urinary metabolites of gerbils with stroke by non-targeted metabolomics technique, and then to clarify the mechanism of the two, as well as their similarities and differences. MethodTwenty-four gerbils were randomly divided into control group(CG), model group(MG), Aconiti Coreani Radix group(RA) and Typhonii Rhizoma group(RT). Except for the CG, ischemic stroke model was constructed using right unilateral ligation of gerbil carotid artery in the remaining groups. Except for the CG and MG, rats in the other groups received whole powder suspension(0.586 mg·g-1) was administered for 14 days. The neurological deficit in each group was scored by Longa scoring on days 0, 3, 7 and 14. After the end of administration, the serum, brain tissue and urine of gerbils in each group were collected, and the rate of cerebral infarction was detected by 2,3,5-triphenyltetrazolium chloride(TTC), and the levels of interleukin(IL)-6, tumor necrosis factor(TNF)-α, malondialdehyde(MDA), superoxide dismutase(SOD), glutathione(GSH), and nitric oxide(NO) in serum and brain tissue were determined by enzyme-linked immunosorbent assay(ELISA). The urine metabolomics of gerbils in each group was studied by ultra performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry(UPLC-Q-Orbitrap-MS), and the data were processed by multivariate statistical analysis, and differential metabolites were screened based on value of variable importance in the projection(VIP) of the first principal component>1 and t-test P<0.05. Metabolic pathway analysis of the screened differential metabolites was performed using Kyoto Encyclopedia of Genes and Genomes(KEGG) database and Metaboanalyst 5.0. ResultCompared with the CG, the neurological deficit score was significantly increased in the MG(P<0.05), compared with the MG, the neurological deficit scores in the RA and RT were significantly reduced after 7 d and 14 d(P<0.05). Compared with the CG, the rate of cerebral infarction was significantly increased in the MG(P<0.05), compared with the MG, the rates of cerebral infarction in the RA and RT were significantly reduced(P<0.05). Compared with the CG, the levels of IL-6, TNF-α, and MDA in the serum and brain tissue of gerbils from the MG were significantly increased(P<0.05), and the levels of SOD, GSH and NO were significantly reduced(P<0.05). Compared with the MG, Aconiti Coreani Radix and Typhonii Rhizoma could down-regulate the levels of IL-6, TNF-α and MDA, and up-regulated the levels of SOD, GSH and NO. A total of 112 endogenous differential metabolites were screened by urine metabolomics, of which 16 and 26 metabolites were called back by Aconiti Coreani Radix and Typhonii Rhizoma, and could be used as potential biomarkers for both treatments in stroke gerbils, respectively. The results of the pathway analysis showed that both Aconiti Coreani Radix and Typhonii Rhizoma had regulatory effects on arginine and proline metabolism, pyrimidine metabolism, and aminoacyl-tRNA biosynthesis. In addition, Aconiti Coreani Radix could also regulate riboflavin metabolism, Typhonii Rhizoma could also regulate purine metabolism, glycine, serine and threonine metabolism, arachidonic acid metabolism, biosynthesis of pantothenate and coenzyme A, and β-alanine metabolism. ConclusionBoth Aconiti Coreani Radix and Typhonii Rhizoma have better therapeutic effects on stroke, with Aconiti Coreani Radix having stronger effects. From the metabolomics results, the main metabolic pathways regulated by Aconiti Coreani Radix involve amino acid metabolism, oxidative stress and so on, while Typhonii Rhizoma mainly involve amino acid metabolism, lipid metabolism, energy metabolism, etc.
