Resumen: Cuando se habla del renacimiento del budismo a finales de la dinastía Ming, los estudiosos echan en falta el estudio de ricos registros locales, regiones específicas y casos típicos. El templo de Jingshan, en Hangzhou, proporciona una muestra de este tipo. Una manifestación destacada del templo de Jingshan a finales de la dinastía Ming es la emergencia de todo un conjunto de anales. Diferentes grupos, como los monjes, los magistrados y la alta burguesía, participaron en la redacción de la historia de Jingshan de forma diacrónica en el mismo espacio. Las diferentes versiones de los Anales de Jingshan revelan el entrelazamiento de los acontecimientos históricos, las tendencias de la época y los deseos de varios grupos en distintas regiones, lo que arroja luz sobre el desarrollo que los registros históricos budistas empezaron a tener con otros clásicos ajenos al budismo en lugar de centrarse únicamente en los sutras budistas. Este proceso pone de manifiesto que el renacimiento del budismo a finales de la dinastía Ming es también un estado activo diacrónico alcanzado por las actividades de personas con diferentes propósitos en un área específica.

Abstract: When discussing the revival of Buddhism in the late Ming Dynasty, scholars lack the study of rich local records, specific regions and typical cases. Jingshan temple in Hangzhou provides such a sample. An outstanding manifestation of Jingshan Temple in the late Ming Dynasty is the emergency of a whole bunch of annals. Different groups such as monks, magistrates, and gentry all participated in the writing of the history of Jingshan diachronically in the same space. Different versions of Jingshan Annals reveal the interweaving of historical events, trends of the times, and the wishes of various groups in distinct regions, shedding light on the development that Buddhist historical records began to involve other classics outside Buddhism instead of only focusing on Buddhist sutras. This process manifests that the revival of Buddhism in the late Ming Dynasty is also a diachronic active state achieved by the people’s activities with different purposes in a specific area.

Abstract To investigate the imaging features and clinic value of magnetic resonance imaging (MRI) and computed tomography (CT) in the diagnosis of clear cell renal cell carcinoma (ccRCC). 139 RCC patients underwent MRI and CT examination before surgery, and the sensitivity, specificity, accuracy, positive and negative predictive values of MRI and CT in diagnosing ccRCC were analyzed and compared. There were 93 true-positive, 11 false-positive, 11 false-negative and 24 true-negative in MRI screening with sensitivity, specificity, accuracy, positive predictive value and negative predictive value of 89.42%, 68.57%, 84.17%, 89.42% and 68.57% respectively. Whereas there were 72 true-positive, 4 false-positive, 32 false-negative and 31 true-negative in CT screening with the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of 69.23%, 88.57%, 74.10%, 94.74% and 49.21% respectively. The sensitivity and negative predictive value of MRI were better than those of CT, while the specificity of CT was better than that of MRI. MRI and CT have respective advantages in the diagnosis of ccRCC. The sensitivity and negative predictive value of MRI are superior to those of CT, while the specificity of CT is superior to that of MRI. Clinically, different examinations are selected according to different situations.

Abstract In order to promote the development and application of small molecule oligopeptides from tilapia (SMOT), its anti-fatigue effect was evaluated by using exhaustive swimming in mice. The results showed that compared with the negative control group, SMOT could significantly prolong the exhausted swimming time of mice, reduce blood lactic acid, blood urea nitrogen and malondialdehyde content, and could significantly improve liver glycogen storage status. Meanwhile, the activities of superoxide dismutase and glutathione peroxidase of the mice gavaged with SMOT were significantly higher than those in the negative control group. In addition, SMOT could increase the activity of immune factor IL-2, stimulate the secretion of sIgA and regulate the level of inflammatory factors. So SMOT had significant anti-fatigue effect. Its anti-fatigue effect was exerted by increasing energy reserves, eliminating the accumulation of metabolites, reducing oxidative stress, and improving the body’s immune function.

Abstract Auxis thazard meat was hydrolyzed by alkaline protease. Auxis thazard hydrolysate (ATH) obtained was isolated by ultrafiltration, size exclusion chromatography and reversed-phase high-performance liquid chromatography. Two peptides with high XOD inhibitory activity purified from ATH were identified as Pro-Asp-Leu (PDL, 344.87 Da) and Ser-Val-Gly-Gly-Ala-Leu (SVGGAL, 504.26 Da) by UPLC-MS/MS, which possessed high in vitro XOD inhibitory activity with the IC50 values of 4.37 ± 0.11 mg mL-1 and 5.59 ± 0.09 mg mL-1, respectively. Molecular simulation indicated that PDL and SVGGAL binded to XOD mainly through hydrogen bond and hydrophobic interaction, thereby inhibiting XOD activity. The research results suggested that the two peptides had potential application prospects as a safe XOD inhibitor substance for hyperuricemia treatment.

Abstract Rosa roxburghii Tratt polysaccharide (RRTP) has various physiological functions that benefit the human body. Therefore, improving the extraction rate of RRTP is of crucial for its promotion and application. In this study, RRTP was extracted using an intermittent ultrasound-assisted enzymatic method, and the effects of five factors on the extraction rate of RRTP were studied using a single factor test and response surface methodology. The regression equation model was significant and had good reliability, and the enzyme concentration, liquid-solid ratio and ultrasonic temperature exhibited a positive and significant effect on the RRTP content. The optimal extraction conditions were a power of 360 W, an enzyme concentration of 2.0%, a liquid-solid ratio of 40 mL/g, an ultrasonic temperature of 60 °C and an ultrasonic time of 25 min. Under these conditions, the crude polysaccharide of RRT (CRRTP) yield was 15.03%, and the RRTP content was 4.50%. The RRTP comprised mannose, rhamnose, galacturonic acid, glucose, galactose and arabinose with molar percentages of 3.39%, 2.91%, 26.73%, 35.16%, 21.21% and 10.61% by High Performance Liquid Chromatography (HPLC), respectively. These results suggested that the intermittent ultrasonic-assisted enzymatic method can improve the extraction rate of RRTP.

Abstract Cassava (Manihot esculenta Crantz) is worldwide the sixth-largest food crop and highly drought resistant. The expression of the myeloblastosis (MYB) family protein MeMYB26 in cassava was previously reported to be significantly up-regulated under water deficit. To study the basic characterization, natural variations and potential functions of MeMYB26 for drought resistance in cassava, the protein was subjected to bioinformatics analysis, multiplex-PCR with next-generation sequencing and candidate association studies. The results indicated that MeMYB26 is a typical transcription factor, with two MYB DNA-binding and transcriptional activation domains. One stop-gained and five nonsynonymous variations in the genomic region of MeMYB26 were significantly associated with drought resistance traits. The results of the scale-free coexpression network showed that the MeMYB26 gene plays a critical role in plant stress resistance, growth and biomass development. It was concluded that MeMYB26 is a reliable candidate gene associated with drought tolerance and biomass storage in cassava.

The aim of this study was to elucidate the concise effects of a traditional herb pair, Curcumae rhizoma-Sparganii rhizoma (CRSR), on uterine leiomyoma (UL) by analyzing transcriptional profiling. The UL rat model was made by intramuscular injection of progesterone and gavage administration of diethylstilbestrol. From 11 weeks of the establishment of the model, rats of the UL+CRSR group were gavaged daily with CRSR (6.67 g/kg). The serum concentrations of progesterone (P) and estradiol (E2) were determined by radioimmunoassay, the uterine index was measured by caliper measurement, and the pathological status was observed by hematoxylin and eosin stain. Gene expression profiling was checked by NimbleGen Rat Gene Expression Microarrays. The results indicated that the uterine mass of UL+CRSR rats was significantly shrunk and serum P and E2 levels significantly reduced compared to UL animals and nearly to the level of normal rats. Results of microarrays displayed the extensive inhibition of CRSR upon the expression of proliferation and deposition of extracellular matrix (ECM)-related genes, and significantly regulated a wide range of metabolism disorders. Furthermore, CRSR extensively regulated key pathways of the UL process, such as MAPK, PPAR, Notch, and TGF-β/Smad. Regulation of the crucial pathways for the UL process and ECM metabolism may be the underlying mechanisms of CRSR treatment. Further studies will provide clear clues for effectively treating UL with CRSR.

ABSTRACT: The impacts of continuous cropping of banana on soil microbiological and biochemical properties are little understood. In this study, we evaluated the variations in soil bacterial community abundance and diversity, microbial biomass carbon (MBC) and nitrogen (MBN) as well as soil enzyme activities involved in C, N and P cycles as affected by continuous cropping of banana. An initial increase in bacterial 16S rRNA copy and soil microbial biomass was observed in the second cropping and then decreased until the fourth cropping. The diversity of bacterial community showed a continuous decrease throughout the experiment. In addition, continuous cropping of banana caused shifts in bacterial community composition and structures. Soil urease and invertase exhibited the highest activities in the second cropping and then decreased gradually from the second to the fourth cropping. The phosphatase activity showed a gradual increase from the first to the third cropping. The bacterial 16S rRNA copy was positively correlated with the contents of MBN and urease activities. The results indicated that continuous cropping of banana was responsible for the disturbance of the bacterial community and that the effect on enzyme activity varies depending on the type of soil enzyme.

L-3-n-butilftalida (L-NMP) é um antioxidante natural, que pode ser utilizado para o tratamento do acidente isquêmico agudo e demência vascular. Este estudo avaliou segurança, tolerância e farmacocinética de comprimidos de L-NBP em chineses voluntários sadios. Este foi um estudo monocêntrico, randomizado, duplo cego, com controle por placebo e doses única e múltipla. Os indivíduos receberam dose única de comprimido de L-NBP de 80, 160, 320 ou 480 mg (n=40) e doses múltiplas de 160 mg duas vezes ao dia, por sete dias (n=12). Amostras de plasma foram analisadas com LC-MS/MS. Os parâmetros farmacocinéticos do L-NBP foram calculados utilizando análise não compartimental, com o programa WinNonlin. A análise estatística foi realizada utilizando-se o programa SPSS. Todos os eventos adversos (EAs) foram moderados e de duração limitada. EAs nesse estudo ocorreram menos frequentemente e mais moderadamente do que os EAs relacionados para cápsulas moles de DL-NBP. Não se observaram eventos adversos graves (EAG), morte ou abandono do estudo. Com dose única, atingiu-se o Cmax em cerca de 1 hora e o t1/2 médio foi de, aproximadamente, 13,76 h. A área sob a curva (ASC) e o Cmax aumentaram com o aumento da dose, mas não se observou proporcionalidade na faixa acima de 160 a 480 mg. No estudo de dose múltipla, o equilíbrio foi alcançado em três dias, com pequeno acúmulo. Em resumo, o comprimido de L-NMP foi bem tolerado em indivíduos chineses saudáveis. O acúmulo pequeno apareceu após doses repetidas.

L-3-n-butylphthalide (L-NBP) is a naturally occurring antioxidant, which can be used for the treatment of acute ischemic stroke and vascular dementia. This study evaluated the safety, tolerability and pharmacokinetics of L-NBP tablets in healthy Chinese volunteers. This was a single-center, randomized, double-blind, placebo-controlled, single- and multiple-dose study. Subjects were assigned to receive a single dose of L-NBP tablet at either 80, 160, 320, or 480 mg (n=40), or multiple doses of 160 mg twice daily for 7 days (n=12). Plasma samples were analyzed with LC-MS/MS. Pharmacokinetic parameters of L-NBP were calculated using non-compartmental analysis with WinNonlin software. Statistical analysis was performed using SPSS software. All adverse events (AEs) were mild and of limited duration; AEs in this study occurred less frequently and more mildly than AEs listed for the DL-NBP soft capsule. No serious adverse event (SAE), death or withdrawal from the study was observed. In the single-dose study, Cmax was reached at about 1 h, and the mean t1/2 was approximately 13.76 h. Area under curve (AUC) and Cmax increased with dose escalation, but dose proportionality was not observed over the range of 160 to 480 mg. In the multiple-dose study, the steady-state was reached within 3 days with slight accumulation. In summary, the L-NBP tablet was well tolerated in healthy Chinese subjects. Slight accumulation appeared after repeated doses.

OBJETIVO: A cirurgia torácica vídeo-assistida (CTVA) tem sido uma intervenção de escolha para o tratamento de pneumotórax espontâneo (PS) com bolha pulmonar. Nosso objetivo foi apresentar uma abordagem de CTVA uniportal unilateral para bulectomia bilateral e avaliar sua eficácia terapêutica. MÉTODOS: Entre maio de 2011 e janeiro de 2012, cinco pacientes foram submetidos a bulectomia bilateral por essa abordagem. Todos apresentavam PS bilateral. A TCAR pré-operatória mostrou que todos os pacientes tinham bolhas bilaterais no pulmão apical. As indicações cirúrgicas, os procedimentos de operação e os desfechos foram revisados. RESULTADOS: Todos os pacientes foram submetidos com sucesso a essa abordagem para bulectomia bilateral, sem complicações intraoperatórias. A mediana de tempo para a retirada do dreno torácico foi de 4,2 dias, e a mediana do tempo de hospitalização no pós-operatório foi de 5,2 dias. A mediana de seguimento pós-operatório foi de 11,2 meses. Um paciente teve recidiva de PE do lado esquerdo três semanas após a cirurgia e foi submetido a abrasão pleural. CONCLUSÕES: A bulectomia bilateral utilizando CTVA uniportal combinada com acesso contralateral ao mediastino anterior é tecnicamente confiável e promove desfechos favoráveis para pacientes com PS que desenvolvem bolhas bilaterais no pulmão apical. Entretanto, para a realização desse procedimento cirúrgico, são necessários cirurgiões com experiência em CTVA, instrumentos toracoscópicos longos, entre outras exigências.

OBJECTIVE: Video-assisted thoracoscopic surgery (VATS) has been a surgical intervention of choice for the treatment of spontaneous pneumothorax (SP) with lung bulla. Our objective was to introduce a uniportal VATS approach for simultaneous bilateral bullectomy and to evaluate its therapeutic efficacy. METHODS: Between May of 2011 and January of 2012, five patients underwent bilateral bullectomy conducted using this approach. All of the patients presented with bilateral SP. Preoperative HRCT revealed that all of the patients had bilateral apical bullae. We reviewed the surgical indications, surgical procedures, and outcomes. RESULTS: All of the patients were successfully submitted to this approach for bilateral bullectomy, and there were no intraoperative complications. The median time to chest tube removal was 4.2 days, and the median length of the postoperative hospital stay was 5.2 days. The median postoperative follow-up period was 11.2 months. One patient experienced recurrence of left SP three weeks after the surgery and underwent pleural abrasion. CONCLUSIONS: Bilateral bullectomy through uniportal VATS combined with contralateral access to the anterior mediastinum is technically reliable and provides favorable surgical outcomes for patients with bilateral SP who develop bilateral apical bullae. However, among other requirements, this surgical procedure demands that surgeons be experienced in VATS and that the appropriate thoracoscopic instruments are available.
