Functional training effects on postural control capacity in sports dancers / Efeitos do treinamento funcional sobre a capacidade de controle postural nos dançarinos esportivos / Efectos del entrenamiento funcional sobre la capacidad de control postural en los bailarines deportivos

ABSTRACT Introduction Functional training can improve athletes' coordination and physical control. Some studies prove the improvement of the strength of the core muscles after functional training. However, the research that questions athletes' dynamic balance submitted to functional training is inconclusive. Objective To analyze the methods of postural control and the impact of functional training on sports dancers. Methods Young sports dancers were randomly divided into control and experimental groups. Both groups performed traditional fitness training, and a functional training protocol was added to the experimental group. Mathematical statistics were employed in the comparative analysis of the fitness of the two groups of athletes before and after training. Results The athletes in the functional training group rapidly achieved postural control ability, with high statistical relevance(P<0.05). Conclusion Athletes need to adopt a scientific and systematic training plan when performing sports dance training. The establishment of the test indexes for postural control ability in athletes can be diversified. Evidence Level II; Therapeutic Studies - Investigating the results.

Bipolarins A-H (1-8), eight new tetracyclic ophiobolin-type sesterterpenes featuring a rare oxaspiro[4.4]nonane moiety, were isolated from cultures of fungus Bipolaris sp. TJ403-B1. Their structures and absolute configurations were elucidated by comprehensive spectroscopic analyses, single-crystal X-ray diffraction experiments, electronic circular dichroism and C NMR calculations. Additionally, compound 5 exhibited significant selective antimicrobial activity against Enterococcus faecalis with an MIC value 8 μg·mL.

Mutation and Clinical Feature of IL-7R in Adult Patients with Acute Lymphoblastic Leukemia / 中国实验血液学杂志

OBJECTIVE@#To investigate the IL-7R gene mutation and clinical features of adult patients with acute lymphoblastic leukemia (ALL).@*METHODS@#One hundred sixty-four cases of newly treated adults with ALL from May 2016 to December 2018 were selected. Targeted and specific next-generation sequencing technology was used to detected a total of 16 types of Ph-like ALL mutations, which include IL-7R mutation, and the cilinical features, rate, types and sites of IL-7R were analyzed.@*RESULTS@#IL-7R mutation was determined in 10 cases of 164 adult patients with ALL and the total mutation frequency was 13 times (6.1%). Out of 10 cases 5 cases were male (50%), 5 cases were female (50%). 6 cases of B-ALL ( 60% ) and 4 cases of T-ALL (40%). The mutation site of all cases was located at exon 6, among which 6 cases had replacement mutations, 3 cases had deletion mutations and 4 cases had insertion mutations. In addition, 1 triple and 1 double mutation of IL-7R were found. Besides, six mutation sites were newly identified, including: c.720_724del, c.723_726del, c.721_722insAGTG, c.727_728insTAACGGCCCCCTGCT, c.727_728insATGCAGGGAGCGAA and c.728_729insAAGTGTCA.@*CONCLUSION@#Six novel mutation sites and a poor manifestation of IL-7R have been explored in this research. Thus more samples are required to study the effects of IL-7R mutation on ALL treatment.

Effect of ursolic acid combined with gemcitabine on proliferation and apoptosis of pancreatic cancer PANC-1 cells / 中国肿瘤生物治疗杂志

@#[Abstract] Objective: To study the effects of ursolic acid cooperated with gemcitabine on proliferation and apoptosis of pancreatic cancer PANC-1 cells. Methods: Human pancreatic cancer cell line PANC-1 was cultured in vitro with ursolic acid and gemcitabine respectively; and MTT assay was used to determine the IC50 of ursolic acid and gemcitabine, thus obtaining the best drug concentration. Ursolic acid (2 µmol/L) and gemcitabine (0.2 µmol/L) alone or in combination was used to treat PANC-1 cells; trypan blue assay was used to test cell viability, and PI staining was used to examine the cell apoptosis; wound healing was used to detect the proliferation and migration of PANC-1 cells. The protein expressions of P-JNK, Bcl-2, IL-6, P-Stat 3, NF-κB and Cox-2 in cells of each treatment group were detected using Western blotting. Results: Both ursolic acid and gemcitabine could significantly inhibit the proliferation of PANC-1 cells, and the IC50 is 13.67 and 2.78 µmol/L, respectively; and the final concentrations were determined at 2 and 0.2 µmol/L for ursolic acid and gemcitabine, respectively. Compared with single drug treatment, the combined treatment exerted a more prominent cell proliferation inhibition effect ([46.47±5.07]% vs [78.38±8.65]%, [76.12±3.23]%, all P<0.05), apoptosis-induction effect ([39.78± 7.01]% vs [20.35±8.51]%, [20.35±8.51]%, all P<0.01) and migration inhibition effect (P<0.01) on PANC-1 cells. Western blotting showed that the combined treatment strongly inhibited Bcl-2 and IL-6 expression, accelerated P-JNK protein expression compared with single drug treatment. Conclusion: The synergistic effect of ursolic acid and gemcitabine enhanced the inhibition on proliferation, migration, and promoted cell apoptosis of human pancreatic cancer cell line PANC-1, the mechanism may be associated with inhibition of Bcl-2, Il-6, P-stat 3 proteins and promotion of P-JNK protein.

Optimization of fermentation conditions for pristinamycin production by immobilized Streptomyces pristinaespiralis using response surface methodology

Response surface methodology was used to optimize the fermentation conditions for the production of pristinamycin by immobilization of Streptomyces pristinaespiralis F213 in shaking flask cultivation. Seed medium volume, fermentation medium volume and shaking speed of seed culture were found to have significant effects on pristinamycin production by the Plackett-Burman design. The steepest ascent method was adopted to approach the vicinity of optimum space, followed by central composite design for further optimization. A quadratic model was built to fit the pristinamycin production. The optimum conditions were found to be seed medium volume of 29.5 ml, fermentation medium volume of 28.8 ml, and shaking speed of seed culture at 204 rpm. At the optimum conditions, a production of 213 mg/l was obtained, which was in agreement with the maximum predicted pristinamycin yield of 209 mg/l. This is the first report on pristinamycins production by immobilized S. pristinaespiralis using response surface methodology.

Hereditary antithrombin deficiency and hyperhomocysteinemia in venous thromboembolic disease / 中国医学科学院学报

Hypercoagulability state is the result of the interplay of genetic predisposition and risk factors. Many key enzymes and reactions in coagulation and anti-coagulation system are involved. Hereditary antithrombin deficiency is one of the major risk factors of venous thromboembolic disease (VTE), whereas hyperhomocysteinemia may also play a role. This article reviews the recent researches on the contributions of these two factors to VTE.
