Abstract Objective: To investigate the safety and efficacy of short-term (7-day) Dual Antiplatelet Therapy (DAPT) with intensive rosuvastatin in Acute Ischemic Stroke (AIS). Methods: In this study, patients with AIS in the emergency department of the hospital from October 2016 to December 2019 were registered and divided into the control group (Single Antiplatelet Therapy [SAPT] + rosuvastatin) and the study group (7-day DAPT + intensive rosuvastatin) according to the therapy regimens. The generalized linear model was used to compare the National Institute of Health Stroke Scale (NIHSS) scores between the two groups during the 21-day treatment. A Cox regression model was used to compare recurrent ischemic stroke, bleeding events, Statin-Induced Liver Injury (SILI), and Statin-Associated Myopathy (SAM) between the two groups during the 90-day follow-up. Results: Comparison of NIHSS scores after 21-day treatment: NIHSS scores in the study group decreased significantly, 0.273-times as much as that in the control group (Odds Ratio [OR] 0.273; 95% Confidence Interval [95% CI] 0.208–0.359; p < 0.001). Comparison of recurrent ischemic stroke during the 90-day follow-up: The therapy of the study group reduced the risk of recurrent stroke by 65% (7.76% vs. 22.82%, Hazard Ratio [HR] 0.350; 95% CI 0.167–0.730; p = 0.005). Comparison of bleeding events: There was no statistical difference between the two groups (7.79% vs. 6.71%, HR = 1.076; 95% CI 0.424–2.732; p = 0.878). No cases of SILI and SAM were found. Conclusions: Short-term DAPT with intensive rosuvastatin effectively relieved the clinical symptoms and significantly reduced the recurrent stroke for patients with mild-to-moderate AIS within 90 days, without increasing bleeding events, SILI and SAM.

SUMMARY: To investigate the correlation between the anatomical morphology of palatal rugae and sex. The study sample consisted of 120 students studying from Shanxi Medical University, of which 60 were females and 60 were males. The digital model of the palatal rugae was obtained by the 3 Shape TRIOS intraoral scanner. And the shapes of palatal rugae were recorded. Association between palatal rugae shape and sex were tested using Chi-square analysis. And logistic regression analysis (LRA) was carried out to calculate the accuracy of gender prediction using rugae shapes. There was a statistically significant difference between males and females in terms of the distribution of wavy and circular palate rugae. The use of logistic regression analysis obtained a sex predictive value of 65 % when all the rugae shapes were analyzed. Digital images of the palatal rugae morphology contribute to more accurate and convenient for data collection and transformation. It was found that rugae patterns can moderately identify the sex of the specific population when multivariate statistics such as LRA is applied. The palatal rugae morphology can be utilized as an assistant measure for sex identification.

En la muestra de este estudio se incluyeron 120 estudiantes de la Universidad Médica de Shanxi, (60 mujeres y 60 hombres). El modelo digital de las rugas palatinas se obtuvo mediante escáner intraoral 3 Shape TRIOS, y se registraron las formas de las rugas palatinas. La asociación entre la forma de las rugas palatinas y el sexo se evaluó mediante un análisis de Chi-cuadrado; para calcular la precisión de la predicción de sexo se llevó a cabo un análisis de regresión logística (ARL) Se observó una diferencia estadísticamente significativa entre hombres y mujeres en términos de la distribución de las rugas palatinas onduladas y circulares. El uso de análisis de regresión logística obtuvo un valor predictivo de sexo del 65 % cuando se analizaron todas las formas de las rugas. Las imágenes digitales de la morfología de las rugas palatinas contribuyen a una recopilación de datos más precisa. En este análisis se determinó que los patrones de rugas pueden identificar relativamente el sexo de una población específica, cuando se aplican estadísticas multivariadas como ARL.

Efeitos da dieta e idade da fêmea em relação à prole e à razão sexual do parasitoide solitário Pachycrepoideus vindemmiae (Rondani) (Hymenoptera, Pteromalidae). As teorias predizem que as fêmeas parasitoides de vespas ajustam a relação razão sexual dos descendentes, de acordo com condições ambientais, em cada oviposição. Entretanto, a dieta e idade das fêmeas também podem afetar o ajuste da razão sexual. Nosso foco foi testar os efeitos da dieta e idade da fêmeas em relação a razão sexual da prole da vespa parasitoide Pachycrepoideus vindemmiae (Rondani, 1875). Nossos resultados mostraram que as fêmeas alimentadas com mel apresentaram uma razão sexual significativa menor de fêmeas, do que aquelas alimentadas apenas com água. A razão sexual (percentagem dos machos) diminuiu com a idade ou longevidade das fêmeas no início da oviposição, mas com aumento no final. Deve haver uma limitação de esperma nas fêmeas de P. vindemmiae no final da oviposição e uma maior frequência de posturas de ovos infertilizados. As fêmeas também fazem posturas de um número maior de ovos infertilizados no início da oviposição, que seria necessário para assegurar o acasalamento entre os descendentes. A prole masculina desenvolverá mais rapidamente e emergirá mais cedo, o que também reduziria o risco de virgindade da prole, com a tendenciosa proporção de razão sexual maior das fêmeas.

Effects of female diet and age on offspring sex ratio of the solitary parasitoid Pachycrepoideus vindemmiae (Rondani) (Hymenoptera, Pteromalidae). Theories predict that females of parasitoid wasps would adjust the offspring sex ratio to environmental conditions in the oviposition patch, but the diet and age of females would also affect the sex ratio adjustment. Our focus was to test the effects of female diet and age on offspring sex ratio of the solitary parasitoid wasp, Pachycrepoideus vindemmiae (Rondani, 1875). Our results showed that females fed with honey had significantly less female biased offspring sex ratio than those fed only with water. Offspring sex ratio (male percentage) decreased with female age or female longevity at the beginning of oviposition but increased at the end. There should be a sperm limitation in P. vindemmiae females at the end of oviposition, and a higher frequency of unfertilized eggs were laid then. Females also laid more unfertilized eggs at the beginning of oviposition, which would be necessary to insure the mating among offspring. Male offspring developed faster and emerged earlier, which would also reduce the risk of virginity in offspring with female-biased sex ratio.

Objective: We aimed to explore the effect of Mycophenolate mofetil (MMF) on loss of renal function and cyst progression compared to rapamycin in Han: SPRD rats. We also sought to assess whether the effect of combination therapy of MMF plus rapamycin was better than that of monotherapy. Methods: Sixty heterozygous (Cy/+) and littermate control (+/+) male Han: SPRD rats were weaned at 4 weeks of age, then divided into four groups randomly to receive different treatments by intragastric administration for 2 months: vehicle-treated group as control, MMF-treated group (20mg/kg/day), rapamycin-treated group (2mg/kg/day), and MMF+Rapa- treated group (MMF 20mg/kg/day plus Rapamycin 2mg/kg/day). Resulls: After 2 months of treatment, rapamycin caused a 22 % decrease in body weight in comparison to the control group, whereas MMF had no significant effect on weight gain. The steady increase of BUN in Cy/+ rats was reduced by 15% in MMF-treated Cy/+ rats. However, rapamycin and combination therapy reduced BUN by 42% and 43%, respectively. CCr was 0.93±0.11ml/min in vehicle-treated Cy/+ rats, 1.67±0.23 ml/min in MMF-treated Cy/+ rats (P<0.05), 1.72±0.44 ml/min and 1.83±0.21 ml/min in rapamycin- and MMF+Rapa-treated Cy/+ rats, respectively (.P<0.01). Cyst volume density was 57.1 % in vehicle-treated Cy/+ rats, 45.2% in MMF-treated Cy/+ rats (P<0.05), 32.9% and 37.7% in rapamycin- and MMF+Rapa-treated Cy/+ rats, respectively (P<0.01). MMF markedly ameliorated interstitial inflammation and fibrosis. Rapamycin showed a similar effect on interstitial inflammation and fibrosis, but to a lesser degree. Conclusion : MMF is more tolerable than rapamycin and can retard deterioration of renal function in Han: SPRD rats, though its effect is weaker than that of rapamycin. Combination therapy does not exert more favorable effect than monotherapy.
