Abstract Objective: The objective of this study was to investigate the effects of activity-based locomotor training (ABLT) on motor function and walking ability in children with spinal cord injury (SCI). Materials and methods: The Chinese National Knowledge Infrastructure, WanFang, VIP, PubMed, and Web of Science databases were searched for related studies, with two reviewers subsequently evaluating the literature quality using the Cochrane Handbook. Results: A total of 11 studies were eligible, while only one met the ABLT standard program criteria. Overall, ABLT significantly improved the lower limb motor function, increased walking speed and distance, and improved the daily living ability of children with SCI. Conclusions: The ABLT strategy is of great significance to the motor function and walking ability of children with SCI. At present, there exist few studies on the application of ABLT for pediatric SCI. Further control studies with a larger sample size are required to improve the ABLT program guidelines for children with SCI.

Abstract A Qingzhi compound-flavor Baijiu (QZCF Baijiu) was developed and the physiochemical factors and microbial community structure in Jiupei (fermented grains) during Baijiu fermentation were revealed. Physiochemical factors of ethanol, moisture and acidity significantly increased in the fermentation, while starch and reducing sugar decreased. The results of high-throughput sequencing showed that Weissella, Pediococcus, Bacillus, Pantoea, Streptococcus, Sphingobacterium, Saccharomyces, Rhizopus, Issatchenkia and Wickerhamomyces were the dominant microorganisms in Jiupei. Moreover, correlation analysis between the physicochemical factors, the dominant microorganisms and the important flavor compounds in QZCF Baijiu production highlighted that the changes of physiochemical factors would lead to the corresponding changes of core microbiota and important flavor substances. Physiochemical factors of starch, reducing sugar and temperature could significantly affect the microbial community structure at the early stage of fermentation, while the influences of ethanol content and acidity became greater at the later stage, resulting in the differences of flavor compounds in Jiupei. Therefore, the growth and metabolism of microbial communities could be regulated by purposefully adjusting the physiochemical factors, thereby improving the flavor and quality of Baijiu. This work enriched the flavor types of Baijiu and provided a reference for the Baijiu-making industries to manage their production process.

Abstract Objectives: This study aimed to compare progression-free survival, overall survival, clinical benefits, and adverse effects in postmenopausal women with hormone receptor-positive and HER2-negative breast cancer who received buparlisib plus fulvestrant against those of women who received dalpiciclib plus fulvestrant, considering ribociclib plus letrozole treatment as the reference standard. Methods: Women received buparlisib plus fulvestrant (BF cohort, n = 108), dalpiciclib plus fulvestrant (DF cohort, n = 132), or ribociclib plus letrozole (RL cohort, n = 150) until unacceptable toxicity was observed. Results: A total of 117 (89 %), 80 (74 %), and 84 (56 %) women in the BF, DF, and RL cohorts, respectively, had clinical benefits. After treatment, the clinical benefits for women and after 42 months of follow-up progression-free survival and overall survival were higher in the DF cohort than in the BF and RL cohorts (p < 0.05 for all). Neutropenia, vomiting, constipation, nausea, diarrhea, and anorexia were reported higher in women of the DF and BF cohorts than in women of the RL cohort. Leukopenia and increased levels of alanine aminotransferase and aspartate aminotransferase were reported to be higher in women in the RL cohort than in women in the DF and BF cohorts. Depression, anxiety, and increased levels of alanine aminotransferase and aspartate aminotransferase were reported to be higher in women in the BF cohort than in women in the DF and RL cohorts. Conclusions: Dalpiciclib plus fulvestrant is effective and comparatively safe in postmenopausal women with hormone receptor-positive and HER2-negative breast cancers. Dalpiciclib, buparlisib, fulvestrant, and ribociclib cause neutropenia, severe depression, adverse gastroenterological effects, and adverse hepatological effects, respectively.

ABSTRACT The objective of this study was to assess the effect of Suanzaoren decoction on stress response of horses in transportation. A total of six male Ili horses were equally divided into Suanzaoren decoction treatment group (n = 3; basal diet supplemented with Suanzaoren decoction, three times/day) and control group (n = 3; basal diet, three times/day). After feeding for five days, all horses were transported for 8 h to simulate stress. Blood and serum samples were obtained before transport (BT), during transport (T), and after transport (AT). Results showed that there was significant interaction between road transport and dietary Suanzaoren decoction supplementation for the white blood cells (WBC), intermediate cell ratio (MID%), granulocyte ratio (GRAN%), alanine aminotransferase (ALT), glucose (GLU), aspartate transaminase (AST), creatine (CK), cortisol (COR), human growth hormone (HGH), adrenocorticotropic hormone (ACTH) and arginine vasopressin content, insulin (INS), and thyronine 4 (T4) in blood and serum. The highest WBC was found in T group. The highest GRAN%, ALT, GLU, AST, CK, T4, ACTH, and INS contents were observed in serum from AT groups, which was decreased by treatment. In conclusion, dietary Suanzaoren decoction supplementation did relieve horse transportation stress. This study provides a useful clinical therapy for relieving transportation stress of horses.

Abstract In this paper, the relationship between Kernel average misorientation (KAM), geometrically necessary dislocation (GND) density and dislocation structures of Nb-bearing austenitic stainless steel under low cycle fatigue (LCF) was studied at 600°C at the total strain amplitude ranged from 0.3% to 1.0%. The results based on EBSD analysis show that the GND density in fatigue specimens gradually increases with the increase of strain amplitude. Under LCF loading, the dislocation structures are mainly planar slip bands (PSBs) and the cell structures. With the increase of strain amplitude, the number of PSBs increases with decrease in width, and the average diameter of cells also decreases. The PSBs originate due to the dynamic strain aging (DSA) effect, and DSA is more significant under high strain amplitude. The average diameter of cell structures has a specific relationship with GND density.

ABSTRACT Purpose: To explore the potential immunomodulatory effects of total extract and different polar parts from Blaps rynchopetera Fairmaire. Methods: Phagocytic activity was evaluated by neutral red assay, and the effect of the immune function was investigated by normal and immunocompromised mice models. Results: In vitro, total extract, as well as chloroform, ethyl acetate, n-butanol and water fractions could individually enhance the phagocytic ability of mouse peritoneal macrophages; in addition, chloroform and ethyl acetate fractions had an increasing tendency when combined stimulation with lipopolysaccharide (LPS). In vivo, ethyl acetate fraction (EAF) could enhance the immune organ index, increase the serum hemolysin level and peripheral blood immune cells of immunocompromised mice, while for normal mice, the effect was inconspicuous. Conclusions: Blaps rynchopetera extracts had noteworthy immunomodulatory effect, especially for individuals with immune disorders.

Abstract The main feature of insomnia is difficulty in starting or maintaining sleep. 5-HT1A receptor and 5-HT2A receptor are two subtypes of the classic central 5-HT neurotransmitter closely related to sleep and wakefulness. To observe the effects of Evodia rutaecarpa acupoint sticking therapy on the mRNA expressions of 5-HT1A and 5-HT2A in the hypothalamus, brainstem, and hippocampus of insomnia rats induced by para-chlorophenylalanine (PCPA). Ten rats were randomly selected as the normal group, and 80 PCPA insomnia model rats were randomly divided into eight groups, including a model group, a positive control group (diazepam group), a low-dose E. rutaecarpa acupoint sticking therapy group (Yongquan acupoint group and Shenque acupoint group; the same applied below), a middle-dose E. rutaecarpa acupoint sticking therapy group, and a high-dose E. rutaecarpa acupoint sticking therapy group. The normal group and the model group did not receive treatment. The positive control group was given diazepam through intragastric administration, and the three-dose E. rutaecarpa acupoint sticking therapy groups were divided into the Yongquan acupoint group and the Shenque acupoint group. After seven days of administration, the rat hypothalamus, brainstem, and hippocampus tissues were taken, and a real-time polymerase chain reaction method was used to detect the mRNA expressions of 5-HT1A and 5-HT2A. E.rutaecarpa acupoint sticking therapy significantly upregulated 5-HT1A mRNA expression and downregulated 5-HT2A mRNA expression in rats with insomnia caused by PCPA. No significant differences were found in the expression between the two acupoints and the expression among the three brain tissues. E. rutaecarpa acupoint sticking therapy can improve insomnia. The mechanism may be related to the upregulation of 5-HT1A mRNA expression and the downregulation of 5-HT2A mRNA expression in brain tissue.

Abstract Due to the good functional characteristics and nutritional value, ovalbumin (OVA) has a widely ranges of applications in food industry. But the characteristics of being susceptible to external conditions, such as processing, storage conditions and food ingredients, makes it display a relative lower functional property and limits its applications. Glycosylation is a natural, green approach of protein modifications that has an impact on its functional properties. In this work, we prepared the OVA-pectin conjugates through wet-heating and ultrasound glycosylation to investigate the effects on the functional and structural properties of OVA. Both wet-heating and ultrasound treated OVA at present of pectin showed higher emulsify and foam properties than untreated OVA. The results of particle size, SDS-PAGE, FT-IR, and SEM indicated that the covalent binding of pectin with OVA molecule. This study suggests that wet-heating and ultrasound glycosylation with pectin are promising method to improve the functional properties of OVA.

Abstract Prodigiosin, a secondary metabolite extracted from Serratia marcescens (S. marcescens), could induce apoptosis in various cancer cells, with however low toxicity on normal cells. The red pigment was extracted from a strain S. marcescens NJZT-1 isolated from soil, which had antibacterial activity. Spectral analyses (LC-ESI-MS, UV-VIS spectrophotometry, infrared spectra and HPLC) and TLC indicated the presence of prodigiosin in the extracellular bacterial culture extracts. The red pigment effectively killed the TSC2-null cells, whose mutation resulted in the progressive and systemic disease LAM. Our findings provide interesting evidence and important basis for the development of new therapeutic compounds with high potential effects against TSC2-null cells.

Abstract Freshness, a very important criterion for pork quality control, is normally assessed by the index of K value. In this paper, Terahertz (THz) spectroscopy was employed to predict K value of pork nondestructively. The THz spectra (0.2~2.0THz) of 80 pork samples with different freshness in the attenuated total reflectance (ATR) mode were acquired. Simultaneously, their K values were determined by high performance liquid chromatography (HPLC). A back propagation artificial neural network (BP-ANN) prediction model of K value was established. The precision of BP-ANN was further improved after optimization by the algorithm of Adaptive boosting (AdaBoost), whose root mean square error of prediction (RMSEP) and correlation coefficient (RP) were 9.89% and 0.84 respectively in the prediction set, indicating that the non-linear models (BP-ANN and BP-AdaBoost) were superior to the linear principal component regression (PCR) model. The topological neural network architecture was much more suitable for analyzing complicated regression relationship between K value and THz spectra. It can be concluded that the THz spectral coupled with BP-AdaBoost algorithm is capable of predicting the pork K value.

Microstructural phase of linepipe steels depends on different isothermal conditions. Thermal cycling testing of X90 linepipe steel was conducted using a thermomechanical simulator. The results have shown that with increased holding time, the microstructure constituents change from the martensite and bainitic ferrites to granular bainite and polygonal ferrite. There was the amount of martensite in the microstructure for isothermal holding times of 5 and 10 s at 700ºC. The effects of the martensite strengthening were weak. The changes of the hardness curve are decided by microstructural phase and the precipitation behavior. The interphase precipitation seems to begin for isothermal holding times greater than 30 s. It has a peak value for isothermal holding time of 600 s. Some fcc (Ti, Nb) (N, C) particles which belong to the MX-type precipitates were obtained at this condition. It is a major microstructural contributor to the hardness. The beneficial effects of the precipitates decreased considerably due to coarsening of the precipitates with prolonged holding, which results in the hardness quickly dropping. As a result, the hardness exhibited a low value after isothermal holding for 3600 s because the extent of precipitation strengthening was lessened and a lot of polygonal ferrites were formed.

Abstract The use of antimicrobial agents is an efficient method to prevent dental caries. Also, nanometric antibacterial agents with wide antibacterial spectrum and strong antibacterial effects can be applied for prevention of dental caries. Objectives: The aim of this study was to evaluate the inhibitory effect of reduced graphene oxide-silver nanoparticles (rGO/Ag) composite on the progression of artificial enamel caries in a Streptococcus mutans biofilm model. Material and Methods: Enamel specimens from bovine incisors were divided into eight treatment groups (n = 13), as follows: group 1 was inoculated with S. mutans grown in Brain Heart Infusion containing 1% sucrose (1% BHIS), as negative control; groups 2-4 were inoculated with S. mutans grown in the presence of different rGO/Ag concentrations (0.08, 0.12, 0.16 mg/mL) + 1% BHIS; group 5-7 were inoculated with S. mutans grown in the presence of different agents (0.16 mg/mL reduced graphene oxide, 0.16 mg/mL silver nanoparticles, 10 ppm NaF) + 1% BHIS; group 8 was mixed with 1% BHIS, without inoculation. Artificial enamel carious lesions were produced by S. mutans biofilm model for 7 days. Confocal laser scanning microscopy and atomic force microscopy were used to analyze roughness and morphology of the enamel surface. Polarized light microscopy and confocal laser scanning microscopy were employed to measure the lesion depth and the relative optical density (ROD) of the demineralized layer. Results: Compared with the control groups, the rGO/Ag groups showed: (a) reduced enamel surface roughness; (b) much smoother and less eroded surfaces; (c) shallower lesion depth and less mineral loss. Conclusion: As a novel composite material, rGO/Ag can be a promising antibacterial agent for caries prevention.

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.
