ABSTRACT Introduction As a high-intensity physical sport, athletics can easily cause serious physical injuries and even psychological problems if not diagnosed after sports fatigue. Objective Study the relationship between sports fatigue and nutritional intervention in track and field. Methods One hundred track and field athletes in a province were investigated. Through literature survey, questionnaire survey, and other data testing, track and field athletes’ sports fatigue and nutritional status were analyzed to determine the necessary relationship between sports fatigue and nutritional intervention. Results The coach’s judgment of sports fatigue during athletes’ training is characterized by a lack of technical accuracy, leading to the decline of athletes’ physical recovery ability and aggravating sports fatigue to a certain extent. As a high-intensity physical exercise, athletics must diagnose sports fatigue in time and provide effective nutritional intervention. Conclusion The research shows that after high-intensity exercise, the diagnosis of sports fatigue in track and field athletes is of great importance in judging the athletes’ physical function, and scientific nutritional intervention plays an important role in athletes’ excessive physical function, improving their sports ability and relieving sports fatigue.

Abstract Hibiscus Sabdariffa L. has important nutritional and medicinal value. Currently, a safe process extraction of reducing sugar from Hibiscus Sabdariffa L. calyx by biological complex enzyme system is seldom investigated. In this experiment, the pectinase and cellulase complex enzyme system was used to optimize the enzymatic hydrolysis of Hibiscus Sabdariffa L. and Box behnken was used to design the experiment. The results showed that there was significant difference in enzymolysis effect of Hibiscus Sabdariffa L under different conditions (p < 0.05). When the enzymolysis temperature was 45 °C, pH 4.5, and the mass volume ratio of material to liquid was 5g:100ml, the optimum conditions were obtained by response surface methodology: the addition amount of pectinase and cellulase complex enzyme was 0.011 g/kg, the ratio of mixed enzyme was 1.36:1, the enzymolysis time was 2.09 h, and the reducing sugar content of Hibiscus Sabdariffa L extract was 3.56 mg/ml. The experimental results of reducing sugar content of Hibiscus Sabdariffa L (3.54 ± 0.1mg / ml) were in good agreement with the predicted value of the equation fitted by response surface. The mixed enzyme system of pectinase and cellulase has the advantages of environmental protection and energy saving, which can provide guidance for industrial production.

Abstract Objective To explore the molecular mechanism of neuropathologic damage induced by radiofrequency ablation at different temperatures. Methods This is basic research, and 36 SD rats were used to construct the neuropathological injury model. The rats were subjected to radiofrequency stimulation at different temperatures and were divided into 6 groups according to the temperature injury: 42°, 47°, 52°, 57°, 62°, and 67°C groups. Conduction time, conduction distance, and nerve conduction velocity were recorded after temperature injury. HE-staining was used to observe the histopathological morphology of the sciatic nerve. The expression of SCN9A, SCN3B, and NFASC protein in sciatic nerve tissue were detected by western blot. Results With the increase in temperature, nerve conduction velocity gradually decreased, and neurons were damaged when the temperature was 67°C. HE-staining showed that the degrees of degeneration of neurons in rats at 47°, 52°, 57°, 62°, and 67°C were gradually increased. The expression of SCN9A, SCN3B protein in 57°, 62°, 67°C groups were much higher than that of NC, 42°, 47°, 52°C groups. However, the expression of NFASC protein in 57°, 62°, 67°C groups was much lower than that of the NC, 42°, 47°, 52°C groups. Conclusion There was a positive correlation between temperature caused by the radiofrequency stimulation to neuropathological damage. The mechanism is closely related to the expression of SCN9A, SCN3B, and NFASC protein in nerve tissue caused by heat transfer injury.

RESUMO Contexto: devido a vários fatores incertos e inesperados da vida, como doenças, desastres naturais, acidentes de trânsito e defeitos congênitos, o número e a proporção de amputações de membros inferiores ainda estão aumentando por muitos motivos, portanto, a pesquisa sobre próteses de membros inferiores é particularmente importante. Objetivo: Este trabalho teve como objetivo estudar a relação entre o exercício em altitude e a função cardiopulmonar. Métodos: Um modelo de alterações anormais da função cardiopulmonar foi estabelecido e, em seguida, 40 praticantes de exercícios de platô foram selecionados, todos chegaram ao Tibete em março de 2017. A relação entre o volume de circulação pulmonar e a pressão interna no tórax foi observada e comparada. A relação entre o reflexo sensorial cardiopulmonar e a respiração do exercício (altitude) e a frequência cardíaca foi analisada. A comparação da função cardiopulmonar de indivíduos de diferentes gêneros foi implementada. Além disso, a influência de diferentes altitudes na função cardiopulmonar dos indivíduos e as mudanças na função cardiopulmonar dos indivíduos antes da partida e durante a primeira, segunda e terceira semanas após a partida foram observadas e comparadas. Resultados: I. À medida que a pressão na cavidade torácica aumentou, o volume de sangue da circulação pulmonar dos indivíduos diminuiu gradualmente, e a diminuição foi mais óbvia no estágio de pressão torácica −50 a 0. II. À medida que o coeficiente do reflexo cardiorrespiratório aumentou, a respiração dos indivíduos e a aceleração compensatória da frequência cardíaca apareceram. III. O rastreamento e o monitoramento dos indicadores cardiopulmonares dos indivíduos revelaram que, com o aumento da altitude, a pressão arterial média, a frequência respiratória e a frequência cardíaca dos indivíduos mostraram uma tendência ascendente, enquanto o valor de saturação de oxigênio no sangue mostrou uma tendência descendente. 4. Por mais alta que fosse a altitude, a pressão arterial média, a frequência respiratória e a frequência cardíaca monitoradas dos indivíduos em exercício foram significativamente superiores aos valores do indicador em repouso, enquanto o valor da saturação de oxigênio no sangue apresentou tendência oposta. V. A pressão arterial média, respiração e frequência cardíaca dos indivíduos na primeira semana foram maiores do que em outros períodos de tempo, mas a saturação de oxigênio no sangue foi relativamente menor. Na segunda e terceira semanas, as mudanças na função cardiopulmonar foram relativamente suaves (todos P <0,05). VI. As mudanças no índice de função cardiopulmonar de sujeitos de diferentes gêneros foram pequenas (p> 0,05).

ABSTRACT Introduction: Due to various uncertain and unexpected factors in life such as diseases, natural disasters, traffic accidents, and congenital disabilities, the number and proportion of lower limb amputations are still rising for many reasons, so the research on lower limb prostheses is particularly important. Objective: This work aimed to study the relationship between altitude exercise and cardiopulmonary function. Methods: A model of abnormal changes in cardiopulmonary function was established, and then 40 plateau exercisers were selected, all of whom arrived in Tibet in March 2017. The relationship between pulmonary circulation volume and internal pressure in the chest was observed and compared. The relationship between cardiopulmonary sensory reflex and exercise (high altitude) breathing and heart rate was analyzed. A comparison of the cardiopulmonary function of subjects of different genders was implemented. Moreover, the influence of different altitudes on the subjects’ cardiopulmonary function and the subjects’ cardiopulmonary function changes before departure and during the first, second, and third week after departure were observed and compared. Results: I. As the pressure in the thoracic cavity increased, the subjects’ pulmonary circulation blood volume gradually decreased, and the decrease was most obvious in the stage of thoracic pressure −50 to 0. II. As the cardiorespiratory reflex coefficient increased, the subjects’ breathing and heart rate compensatory acceleration appeared. III. Tracking and monitoring of the subjects’ cardiopulmonary indicators revealed that with the increase in altitude, the subjects’ average arterial pressure, respiratory frequency, and heart rate all showed an upward trend, while the blood oxygen saturation value showed a downward trend. IV. No matter how high the altitude was, the average arterial pressure, respiratory rate, and heart rate monitored of the subjects under exercise were significantly superior to the indicator values under resting state. In contrast, the blood oxygen saturation value showed the opposite trend. V. The subjects’ average arterial pressure, respiration, and heart rate in the first week were higher than other periods, but the blood oxygen saturation was relatively lower. In the second and third weeks, the changes in cardiopulmonary function were relatively smooth (all P<0.05). VI. The changes in the index of the cardiopulmonary function of subjects of different genders were small (p>0.05). Conclusion: Through modeling, the results of the plateau environment on the cardiopulmonary function of the body were made clearer, and these research data provided theoretical references for the training of the sports field in the plateau area. Level of evidence II; Therapeutic studies - investigation of treatment results.

This study aimed to perform a meta-analysis to determine the efficacy and safety of emricasan. Nine databases were searched for clinical trials investigating the efficacy of emricasan treatment in patients with liver cirrhosis or fibrosis. A manual search was conducted to identify the missing trials. The quality of the included studies was assessed using the revised Cochrane risk of bias tool. Efficacy of emricasan treatment was defined as a positive change in apoptosis-related parameters from baseline to the last follow-up visit. Overall, emricasan treatment is more effective in patients with liver cirrhosis or fibrosis than placebo (standardized mean difference [SMD] [95% confidence intervals (CI)]=0.28 [0.14; 0.41]). No significant change in model for end-stage liver disease (MELD) score between the emricasan and placebo groups was noted (SMD [95% CI]=0.18 [-0.01; 0.36]; p=0.058). A 50 mg dose of emricasan had the highest efficacy rate compared to placebo (SMD [95% CI]=0.28 [0.06; 0.50]; p=0.012), followed by the 5 mg dosing regimen (SMD [95% CI]=0.28 [0.06; 0.50]; p=0.012). Treatment with emricasan resulted in significant reductions in ALT (mean difference (MD) [95% CI]=-5.89 [-10.59; -1.20]; p=0.014) and caspase3/7 levels (MD [95%CI]=-1215.93 [-1238.53; -1193.33]; p<0.001), respectively. No significant increase in the rate of overall adverse events was noted (OR [95% CI]=1.52 [0.97; 2.37]; p=0.069). Treatment with emricasan is more effective in improving liver function and apoptosis parameters compared to placebo, with a well-tolerated safety profile. However, due to the poor quality of the analyzed studies, the small number of trials and patients, and the short follow-up periods, more robust trials are still warranted.

Abstract Papaver setigerum is an annual herb that is closely related to the opium poppy, P. somniferum. Genetic resources for P. setigerum are scarce. In the present study, we assembled the complete chloroplast (cp) genome of P. setigerum based on genome skimming data, and we conducted comparative cp genome analyses to study the evolutionary pattern in Papaveraceae. The cp genome of P. setigerum is 152,862 bp in length with a typical quadripartite structure. Comparative analyses revealed no gene rearrangement in the Papaveraceae family, although differences were evident in genome size, gene losses, as well as inverted repeats (IR) region expansion and contraction. The rps15 gene has been lost from the genomes of Meconopsis racemosa, Coreanomecon hylomeconoides, P. orientale, P. somniferum, and P. setigerum, and the ycf15 gene is found only in C. hylomeconoides. Moreover, 13 cpDNA markers, including psbA-trnH, rps16-trnQ, trnS-trnG, trnC-petN, trnE-trnT, trnL-trnF, trnF-ndhJ, petA-psbJ, ndhF-rpl32, rpl32-trnL, ccsA-ndhD, ndhE-ndhG, and rps15-ycf1, were identified with relatively high levels of variation within Papaver, which will be useful for species identification in this genus. Among those markers, psbA-trnH is the best one to distinguish P. somniferum and P. setigerum.

Abstract In this work, the vapor-liquid equilibrium experimental data for the systems of isopropyl chloroacetate + isopropanol, isopropyl chloroacetate + cyclohexane and isopropyl chloroacetate + benzene were measured by a modified Rose-type recirculating still under the pressure of 101.3 kPa. The thermodynamic consistency of the measured data was verified by the Herington and van Ness methods, respectively. The experimental data were correlated by the NRTL, Wilson, and UNIQUAC activity coefficient models, and the corresponding interaction parameters of the three models were obtained. The root-mean-square deviations between the experimental data and calculated results for the temperature and the mole fraction of the vapor phase were less than 0.58 K and 0.0066, respectively. In addition, the excess Gibbs energy was calculated for the three systems.

Abstract A selective and sensitive liquid chromatography tandem with mass spectrometry was developed and validated for accurate determination of monotropein in rat plasma and tissues. All biological samples were prepared by simple protein precipitation method using catalpol as an internal standard. The analyte and internal standard were separated on a C18 analytical column with 2 min of run time, at flow rate of 0.5 ml/min. The detection was performed on a triple-quadrupole tandem mass spectrometer equipped with negative-ion electrospray ionization by selected-reaction monitoring of the transitions at m/z 389→147 for monotropein and m/z 361→169 for the internal standard. The calibration curves for plasma and tissue samples were linear over the concentration range of 4–2000 ng/ml, with a lower limit of quantification of 4 ng/ml. The method was successfully applied to a pharmacokinetic and tissue distribution study of monotropein in rats.

Abstract The leaves of Syringa oblata Lindl., Oleaceae, had been extensively used as a folk medicine to treat various infections, heal inflammations, icteric hepatitis and acute mastitis. The study was designed to evaluate the hepatoprotective activity of S. oblata leaves ethanol extract against CCl4-induced hepatotoxicity in primary hepatocytes and mice with the indicator of glutathione S-transferase alpha 1. The hepatoprotective effects of S. oblata leaves ethanol extract were evaluated on the basis of liver histopathology and biochemical parameters as well as hepatic oxidative stress markers. The results showed that CCl4 negatively modulated biochemical parameters and liver antioxidant activities. However, the use of S. oblata leaves ethanol extract restored altered-serum biochemical parameters and liver antioxidant activities in a dose-dependent manner. Importantly, the trends in S-transferase alpha 1 were similar to alanine aminotransferase and aspartate aminotransferase level, and S-transferase alpha 1 was suggested to be a marker for the evaluation of hepatoprotective activity of S. oblata leaves ethanol extract. Histopathological examination showed that CCl4 causes significant hepatic injury relative to control group. The above findings suggested that S. oblata leaves ethanol extract has hepatoprotective effects against CCl4-induced hepatic injury and S-transferase alpha 1 may be an indicator to evaluate the protective effects of S. oblata leaves ethanol extract.

ABSTRACT The enzyme 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR; EC1.1.1.34) catalyzes the first committed step of isoprenoids biosynthesis in Mevalonate (MVA) pathway. Here we report for the first time the cloning and characterization of a full-length cDNA encoding HMGR from Fritillaria cirrhosa (FcHMGR), a bulbous medicinal plant. The full-length cDNA of FcHMGR was 2072 base pair (bp), containing a 1680-bp open reading frame. Bioinformatical analyses revealed that FcHMGR had HMG CoA-binding domains and two NADPH binding domains, which are required for HMGR activity. Quantitative real-time PCR (qRT-PCR) analysis revealed that FcHMGR expressed high in mature bulbs. A truncated version of FcHMGR protein lacking the N-terminal 249-bp GC rich area was expressed in Escherichia coli. The crude cell lysate containing the recombinant protein showed a better HMGR activity than the control and the relative enzyme activity was calculated to be 1.62 U/mg. The cloning, characterization and functional analysis of FcHMGR gene allowed us to further understand the role of FcHMGR involved in steroidal alkaloid biosynthetic pathway in F. cirrhosa at the molecular level.

Background Cysteine proteinase inhibitor (cystatin, CPI) is one of the most important molecules involved in plant development and defense, especially in the regulation of stress responses. However, it is still unclear whether the Jatropha curcas CPI (JcCPI) gene functions in salinity response and tolerance. In this study, the sequence of the JcCPI gene, its expression pattern, and the effects of overexpression in Escherichia coli and Nicotiana benthamiana were examined. The purpose of this study was to evaluate the regulatory role of JcCPI in salinity stress tolerance. Results The CPI gene, designated JcCPI, was cloned from J. curcas; its sequence shared conserved domains with other plant cystatins. Based on a transcription pattern analysis, JcCPI was expressed in all tissues examined, but its expression was highest in the petiole. Additionally, the expression of JcCPI was induced by salinity stress. A potential role of JcCPI was detected in transgenic E. coli, which exhibited strong CPI activity and high salinity tolerance. JcCPI was also transferred to tobacco plants. In comparison to wild-type plants, transgenic plants expressing JcCPI exhibited increased salinity resistance, better growth performance, lower malondialdehyde (MDA) contents, higher anti-oxidase activity, and higher cell viability under salinity stress. Conclusions Based on the results of this study, overexpression of JcCPI in E. coli and N. benthamiana conferred salinity stress tolerance by blocking cysteine proteinase activity. The JcCPI gene cloned in this study will be very useful for the development of stress-tolerant crops.

MÉTODOS: Entre junho de 2008 e outubro de 2010, 76 pacientes foram submetidos à reconstrução do LCA em feixe único pelo enxerto autógeno de tendão semitendíneo egrácil.Todos os casos foram divididos aleatoriamente em dois grupos de acordo como método de preparação do túnel femoral: grupo transtibial (TT) (n=38) e grupo ântero-medial (AM) (n=38). Foi usado o escore Lysholm para joelho. O relaxamento anterior do joelho a 30° sob força tênsil de 133,32N foi determinado com o medidor KT-1000 no pré e no pós-operatório nos dois grupos. RESULTADOS: Sessenta e cinco pacientes (grupo TT, 34; grupo AM,31)foram acompanhados por mais de 12 meses, com uma taxa de follow-up de 86%.A pontuação do Lysholm para joelho e do relaxamento anterior medido pelo KT-1000 aos 12 meses de pós-operatório foi significativamente melhor do que antes da reconstrução.As pontuações de Lysholme do relaxamento KT-1000 não foram significativamente diferentes comparando os grupos TT e AM após a operação. CONCLUSÃO: A preparação do túnel femoral através do túnel tibial ou da porta ântero-medial na reconstrução do ligamento cruzado anterior em feixe único mostrou os mesmos efeitos terapêuticos.

PURPOSE: To prospectively compare therapeutic effect of femoral tunnel preparation through the tibial tunnel and the anteromedial (AM) portal in single-bundle anterior cruciate ligament (ACL) reconstruction. METHODS: Between June 2008 and October 2010, 76 patients underwent single-bundle ACL reconstruction by autogenous grafting of semitendinosus and gracilis tendon. All cases were randomly divided into two groups according to the method of femoral tunnel preparation: transtibial (TT) group (n=38) and anteromedial (AM) group (n=38). Lysholm knee score and the KT-1000 anterior laxity at 30° of pre-and post-operation were assessed for two groups. RESULTS: Sixty-five patients (TT group, 34; AM group, 31) were followed up for more than 12 months, with a follow-up rate of 86%. The Lysholm knee score and the KT-1000 anterior laxity 12 months after operation were significantly better than before reconstruction. The Lysholm knee score and the KT-1000 anterior laxity were not significantly different between the TT and AM groups after operation. CONCLUSION: Femoral tunnel preparation through tibial tunnel or the anteromedial portal in single-bundle anterior cruciate ligament reconstruction shows same therapeutic effects.

OBJECTIVE: The aim of this study was to determine whether and how the diameter of the vein that gives rise to the inflowing vein of the esophageal and gastric fundic varices secondary to posthepatitic cirrhosis, as measured with multidetector-row computed tomography, could predict the varices and their patterns. METHODS: A total of 106 patients with posthepatitic cirrhosis underwent multidetector-row computed tomography. Patients with and without esophageal and gastric fundic varices were enrolled in Group 1 and Group 2, respectively. Group 1 was composed of Subgroup A, consisting of patients with varices, and Subgroup B consisted of patients with varices in combination with portal vein-inferior vena cava shunts. The diameters of the originating veins of veins entering the varices were reviewed and statistically analyzed. RESULTS: The originating veins were the portal vein in 8% (6/75) of patients, the splenic vein in 65.3% (49/75) of patients, and both the portal and splenic veins in 26.7% (20/75) of patients. The splenic vein diameter in Group 1 was larger than that in Group 2, whereas no differences in portal vein diameters were found between groups. In Group 1, the splenic vein diameter in Subgroup A was larger than that in Subgroup B. A cut-off splenic vein diameter of 8.5 mm achieved a sensitivity of 83.3% and specificity of 58.1% for predicting the varices. For discrimination of the varices in combination with and without portal vein-inferior vena cava shunts, a cut-off diameter of 9.5 mm achieved a sensitivity of 66.7% and specificity of 60.0%. CONCLUSION: The diameter of the splenic vein can be used to predict esophageal and gastric fundic varices and their patterns.
