ABSTRACT
Purpose@#The consequences of severe traumatic injury extend beyond hospital admission and have the potential for long-term functional, psychological, and economic sequalae. This study investigated patient outcomes 6 months following major trauma. @*Methods@#Using the National Trauma Registry, database of patients who were admitted between 2016-18 in a tertiary trauma hospital for major trauma [Injury Severity Score (ISS) ≥ 16] a review was performed on 6-month outcomes [including functional outcomes, self-reported state of health and outcome scores (EuroQol-5 Dimension score and Glasgow Outcome Scale Extended)].Result: There were 637 patients who were treated for major trauma (ISS ≥ 16); the median age was 64 years (range 16-100) and 435 (68.3%) patients were male. The most common injury mechanisms included falling from height (56.5%) and motor vehicle accident (27.0%). The median ISS was 24 (range 16-75). After 6 months, 87.6% of responders were living at home, 25.0% were back to work, and 55.1% were ambulating independently. The median self-rated state of health was 73 at baseline and 64 at 6 months. Age and length of stay were independent predictors of return to ambulation using multivariate analysis. Age, Abbreviated Injury Scale external, Glasgow Coma Scale on Emergency Department arrival, heart rate, and need for transfusion were independent predictors of failure to return to work at 6 months using multivariate analysis. Charlson Comorbidity Index, Glasgow Coma Scale on arrival, temperature, pain and need for inpatient rehabilitation were independent predictors of mortality at 6 months. @*Conclusion@#Recovery from major trauma is multi-faceted and requires a team-based approach well beyond discharge.
ABSTRACT
Objective:To investigate characteristics of the 18F-flurodeoxyglucose ( 18F-FDG) uptake intensity and ranges in distinct hepatic alveolar echinococcosis lesions. Methods:The clinical data of 39 patients with position emission tomography during Jan 2017 to Dec 2019 in the First Affiliated Hospital of Xinjiang Medical University were enrolled. Among them, there were 17 males and 22 females, aging from 15 to 65 years (median 34 years). Lesions were classified into six groups based on heterogenic scales of calcification and liquefaction: A. non-calcified and non-liquefied ( n=7); B. obvious calcified and non-liquefied ( n=7); C. partial calcified and partial liquefied( n=10); D. obvious calcified and partial liquefied ( n=5); E. partial calcified and subtotal liquefied ( n=5); F. obvious calcified and subtotal liquefied ( n=5). Tumor to background ratio (TBR) and width (W) of lesion infiltrative boundary were measured and calculated. Statistical comparison using Mann-Whitney U test as well as correlation analysis was performed. Results:TBR values [ M( Q1, Q3)] for each group were 4.40(3.66, 7.03), 2.55(1.69, 3.60), 3.73(3.37, 5.21), 2.90(2.75, 3.60), 3.80(3.49, 6.36), 2.49(2.21, 3.97), among which A>B, A>D, A>F, C>B, E>B ( U=3.0, 4.0, 4.5, 11.0, 5.0, all P<0.05); From the perspective of the calcification in each group, it was found that the lighter the calcification was, the greater the TBR value was. W values [ M( Q1, Q3)] for each group were [12.5(10.0, 19.5), 11.2(10.5, 12.5), 12.2(10.9, 13.2), 7.8(7.3, 9.3), 10.0(7.3, 13.4), 7.3(6.8, 7.6)] mm, among which A>D, A>F, B>D, B>F, C>D, C>F (all U=0, all P<0.05); According to the degree of calcification and liquefaction of lesions in each group, the lighter the calcification was, the greater the W value was; The heavier the liquefaction was, the smaller the W value was. A mild strength linear correlation has been observed between the TBR value and W value ( r=0.4136, P<0.05). Conclusions:Less calcification and liquefaction implicated higher 18F-FDG uptake intensity and wider range. Radical resection margins and tissue sampling should be individualized based on different lesion features in surgical treatment.
ABSTRACT
Coronary heart disease （CHD） with atherosclerosis is a common chronic disease worldwide， and anxiety and depression are potential and crucial risk factors for adverse prognosis in CHD. Chaihu Longgu Mulitang （CLMT）， first mentioned in the Shang Han Lun （《伤寒论》）， is a classic prescription for treating Shaoyang diseases combined with disturbance of the mind and spirit， with the effects of harmonizing Shaoyang and calming the mind. Current research on mechanisms has shown that CLMT can play a role in CHD complicated with anxiety and depression through multiple pathways， including regulating related signaling pathways， inhibiting the expression of inflammatory factors， improving oxidative stress damage， modulating neurotransmitter levels， suppressing the hypothalamic-pituitary-adrenal axis， promoting mobilization of mesenchymal stem cells from the bone marrow， and inhibiting platelet activation. Clinical studies have demonstrated that CLMT significantly improves symptoms such as angina and insomnia caused by CHD complicated with anxiety and depression， effectively reduces negative emotions， improves traditional Chinese medicine （TCM） syndrome scores， and decreases levels of inflammatory factors. Furthermore， it has fewer adverse reactions and higher safety than conventional western medicine treatments. This article provides a review of the mechanisms and clinical studies of CLMT in the treatment of CHD complicated with anxiety and depression based on a comprehensive analysis of literature from the China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， PubMed， and other databases in the past 15 years， in order to provide references for further research on the use of CLMT in the management of CHD complicated with anxiety and depression.
ABSTRACT
Our studies were aimed to explore the effect and mechanism of the inhibition of the formation of vasculogenic mimicry (VM) in human glioblastoma cells by Xihuang pill (XHP) medicated serum through regulating the hypoxia inducible factor-1α (HIF-1α)/vascular endothelial growth factor A (VEGFA)/vascular endothelial growth factor receptor 2 (VEGFR2) signaling pathway. The medicated serum of XHP was prepared by gavage for 7 days to male SD rats (approval number of animal experiment ethics: 202105A051). The hypoxia model of U251 cells was established using 200 μmol·L-1 of CoCl2. After treatment with XHP-medicated serum, cell viability and proliferation of U251 cells were detected by CCK-8 and cell cloning experiment. Cell apoptosis and cell cycle of U251 cells were determined by flow cytometry. Cell migration and invasion were evaluated by wound healing and Transwell invasion assay. The formation of VM was assessed by three-dimensional cell culture of U251 cells. The protein expression levels of HIF-1α, VEGFA, VEGFR2, phosphorylated-VEGFR2 (p-VEGFR2), vascular endothelial-cadherin (VE-cadherin), Eph receptor tyrosine kinases A2 (EphA2), matrix metalloproteinase 2 (MMP2), matrix metalloproteinase 14 (MMP14) and laminin γ2 in U251 cells were detected by Western blot. The results showed that 10% XHP-medicated serum had little effect on the cell viability, proliferation, apoptosis and cell cycle of U251 cells under hypoxia. Compared with the model group, 10% XHP-medicated serum at 1.0, 1.5 and 2.0 h significantly decreased the migration rate (P < 0.01) and the number of invading U251 cells (P < 0.01). 10% XHP-medicated serum at 2.0 h significantly suppressed the formation of VM tubular structures in U251 cells under the condition of hypoxia (P < 0.01). Western blot experiment showed that 10% XHP-medicated serum significantly down-regulated the expression of HIF-1α, VEGFA, phospho-VEGFR2, VE-cadherin, EphA2 and MMP14 proteins (P < 0.05). In conclusion, XHP could inhibit the formation of VM in human glioblastoma U251 cells to suppress the angiogenesis by down-regulating the HIF-1α/VEGFA/VEGFR2 signaling pathway.

ABSTRACT
Pear is one of the main fruits with thousands of years of cultivation history in China. There are more than 2000 varieties of pear cultivars around the world, including more than 1200 varieties or cultivars in China (Legrand et al., 2016). Xinjiang Uygur Autonomous Region is an important pear production region in China with 30 of varieties or cultivars. Pyrus sinkiangensis is the most popular variety, which is mainly distributed in Xinjiang (Zhou et al., 2018). Chlorogenic acid (CGA), p-coumaric acid, and arbutin are the main polyphenols in pear fruit, and their levels show great differences among different varieties (Li et al., 2014). CGA is a potential chemo-preventive agent, which possesses many important bioactivities including antioxidant, diabetes attenuating, and anti-obesity (Wang et al., 2021). Therefore, the specific CGA content of a variety is considered the embodiment of the functional nutritional value of pears.

Objective:To explore a fast and accurate method to diagnose children's pneumonia according to respiratory signals, so as to avoid the cancer induction caused by traditional X-ray examination.Methods:A Mach Zehnder optical fiber sensor was used to build a respiratory signals(RSPs) detection system, and the RSPs of the monitored children were extracted according to the vibration signal generated by the children's lung rales. Preprocessing methods such as the discrete cosine transform(DCT) were used to compress and denoise the RSPs. Multi-feature extraction of RSPs was conducted through signal processing methods such as the Hilbert transform and autoregressive (AR) model spectrum estimation. A support vector machine (SVM) classification model was constructed to classify the collected RSPs.Results:The accuracy rate of the proposed RSP classification of children with or without pneumonia was 94.41%, which was higher than the previous methods.Conclusions:The children's pneumonia diagnosis system based on an optical fiber sensor has a higher detection accuracy, and is expected to be widely used in clinical practice.
ABSTRACT
Objective:To investigate the relationship between phase behavior of curcumin （CUR） from self-nanoemulsion drug delivery system （SNEDDS） and stability of the formed nanoemulsion in artificial gastrointestinal fluid. Method:The growth rate of precipitation after dispersion of CUR-SNEDDS was expressed by the change tendency of CUR supersaturation-time curve. The effect of drug loading on crystal nucleation and growth was investigated by ultraviolet-visible spectrometry and polarized light microscope， respectively. X-ray powder diffraction （XRD） and differential scanning calorimetry （DSC） were used to analyze the precipitation forms of CUR-SNEDDS with different drug loading in artificial gastrointestinal fluid. At the same time， the effect of drug loading on the quality stability of nanoemulsion formed by CUR-SNEDDS in artificial gastrointestinal fluid was investigated. Result:In the artificial gastrointestinal fluid， with the increase of drug loading， the area under the supersaturation-time curve of CUR was increased （100% drug loading≈90% drug loading>75% drug loading）， the crystallization nucleation and growth rate were accelerated （100% drug loading>90% drug loading>75% drug loading）， the amorphous proportion in the precipitation composition decreased， the nanoemulsion droplets adhered and distributed unevenly， the particle size and dispersivity were increased. Conclusion:High drug loading promotes the nucleation and growth of crystals， and increases the proportion of crystal forms in the precipitation composition， which leads to the decrease in the stability of the formed nanoemulsion. Therefore， it is suggested that the drug loading of CUR-SNEDDS needs to be controlled below 90%.
ABSTRACT
The study is aiming at investigating the application of entropy weight TOPSIS method in the comparison of the scavenging effect of DPPH, ABTS and hydroxyl radical and the inhibition effect of xanthine oxidase(XOD) and lipoxygenase(LOX) of Chrysanthemum indicum. The DPPH, ABTS, salicylic acid and spectrophotometry were used to determine the scavenging effect of DPPH, ABTS and hydroxyl radical and the inhibition effect of xanthine oxidase(XOD) and lipoxygenase(LOX) of Ch. indicum from 31 different areas in vitro. Take the half inhibition rate of as the evaluation index, two principal components were extracted by the principal component analysis, and their cumulative contribution rate reached at 92.4%. The different areas of Ch. indicum could be divided into Dabei Mountain and Qinling-Taihang Mountain by use principal component to analysis. The entropy weight TOPSIS method was used to objectively assign weights to five indexes, calculate the weight of each index and set up the best and worst scheme of the evaluation object, and the relative proximity(C_i) was used as the measure to construct the multi-index comprehensive evaluation model of Ch. indicum. And then sort with the relative proximity value. The results showed that the relative proximity was between 0.098 and 0.983 which represents there were significant differences in the scavenging effect of DPPH, ABTS and hydroxyl radical and the inhibition effect of xanthine oxidase(XOD) and lipoxygenase(LOX) between extracts of Ch. indicum from different areas. The Ch. indicum from Dabie Mountain area have a relatively high relative degree of measurement and high-quality ranking. Taken together, the quality of Ch. indicum.from the Dabie Mountain area is better. The index weight coefficient and the classification result of producing area are basically consistent with the result of principal component analysis. The results show that the TOPSIS method based on entropy weight method can be used to evaluate the comprehensive quality of Ch. indicum.

ABSTRACT
Human alveolar echinococcosis is a chronic infectious disease caused by Echinococcus multilocularis infection. It predominantly injuries the liver and grows like the malignant tumor. The therapeutic options and prognosis depend on types of human alveolar echinococcosis, clinical stages, biological activity, vascular invasion, pathological characteristics, and patient's immune status. However, despite of multiple classification methods, there are still lacking of comprehensive typing schemes. which leads to inappropriate diagnosis and therapy. This research systematically reviewed the recent studies on human alveolar echinococcosis at home and abroad and analyzed the classifications based on ultrasound, computer tomography, magnetic resonance imaging, positron emission computed tomography, serology and pathology, and some novel technologies and summarized the individual advantage and disadvantage for each classification Relationships and their advantages plus disadvantages have been assessed comprehensively. Meanwhile, the possible reference factors or theoretical basis for optimized future classification are proposed, in order to establish a unified classification system to provide guidance for clinical diagnosis and treatment.
ABSTRACT
ObjectiveTo investigate the influence of endoplasmic reticulum stress (ERS) on some inflammatory mediators during the progression of hepatic alveolar echinococcosis (HAE) and its clinical significance. MethodsA total of 15 patients with HAE who underwent partial liver resection in Qinghai University Affiliated Hospital from June 2018 to September 2019 were enrolled, and the marginal zone of HAE lesion was resected as AE group; 15 normal liver tissue samples collected during the same period of time were selected as control group. Western blot and qRT-PCR were used to measure the protein and mRNA expression of protein kinase R-like ER kinase (PERK), CCAAT/enhancer-binding protein homologous protein (CHOP), caspase-12, and glucose-regulated protein-78 (GRP-78), and q-PCR was used to measure the mRNA expression of interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor (TNF). The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the t-test was used for comparison of normally distributed continuous data between two groups; a Pearson correlation analysis was performed to investigate the correlation between two variables. ResultsCompared with the control group, the AE group had significantly higher protein expression levels of PERK, CHOP, caspase-12, and GRP78 (U=4.165, 3.461, 2.577, and 3.344, all P＜0.001) and their mRNA expression levels (t= 34003, 4.461, 53.573, and 55.224, all P＜0.001). The AE group had significantly higher mRNA expression levels of IL-1β, IL-6, and TNF than the control group (t=6.090, 12.578, and 53.573, all P＜0.001). The protein expression levels of PERK, CHOP, caspase-12, and GRP-78 were positively correlated with the mRNA expression levels of IL-1β, IL-6, and TNF (all r＞0.700, all P≤0.05). ConclusionPositive correlation is observed between the activation of ERS and inflammatory mediators in HAE, and excessive activation of ERS can change the secretion of several inflammatory mediators to exacerbate liver injury, while further studies are needed to clarify the specific mechanism.

OBJECTIVES@#To study the clinical features and prognosis of children with acute leukemias of ambiguous lineage (ALAL) under different diagnostic criteria.@*METHODS@#A retrospective analysis was performed on the medical data of 39 children with ALAL who were diagnosed and treated from December 2015 to December 2019. Among the 39 children, 34 received treatment. According to the diagnostic criteria for ALAL by World Health Organization and European Group for the Immunological Characterization of Leukemias, the 39 children were divided into two groups: ALAL group (@*RESULTS@#The 34 children receiving treatment had a 3-year event-free survival (EFS) rate of 75%±9% and an overall survival rate of 88%±6%. The children treated with acute myeloid leukemia (AML) protocol had a 3-year EFS rate of 33%±27%, those treated with acute lymphoblastic leukemia (ALL) protocol had a 3-year EFS rate of 78%±10%, and those who had no remission after induction with AML protocol and then received ALL protocol had a 3-year EFS rate of 100%±0% (@*CONCLUSIONS@#ALL protocol has a better clinical effect than AML protocol in children with ALAL, and positive MRD after induction therapy suggests poor prognosis. Hyperleukocytosis and adverse genetic changes are not observed in children with myeloid expression, and such children tend to have a good prognosis, suggesting that we should be cautious to take it as ALAL in diagnosis and treatment.

The effects of four natural organic soil amendments on the quality and pesticide residues of Panax notoginseng were investigated through field experiments and the suitable dosage ratio of each soil amendment was selected to provide a new idea for the pollution-free cultivation of P. notoginseng. The four natural organic soil amendments used in this study were Jishibao, Jihuo, Fudujing, and omnipotent nutrients, which were produced by mixed fermentation of aboveground parts of different plants, biological waste residue, and biochar. During the experiments, only four soil amendments were applied to P. notoginseng instead of any pesticides and fertilizers. The experiment was designed as four factors and three levels. There were three dosage gradients(low, medium, and high) for Jishibao(A), Jihuo(B), Fudujing(C), and omnipotent nutrients(D). When the dosage of one soil amendment changed, the do-sage of the other soil amendments remained medium. There were 10 groups in addition to the soil amendment-free group as control(CK). The results showed that the four soil amendments could significantly improve the growth environment of P. notoginseng and increase the seedling survival rate and saponin content of P. notoginseng. The seedling survival rates of the treatment groups increased by 8.24%-30.05% as compared with the control group. Furthermore, the content of pesticide residues in P. notoginseng was too low to be detected, and that of heavy metals in P. notoginseng was far lower than the specified content in the Chinese Pharmacopoeia(2020). The optimal effect was achieved at medium dosage for all the soil amendments with the highest content of saponins, high seedling survival rate, and significantly reduced heavy metals, such as lead, cadmium, arsenic, and mercury.

OBJECTIVE@#To compare the clinical effect on intestinal dysfunction of spinal cord injury (SCI) between the comprehensive therapy of moxibustion (moxibustion for opening the governor vessel and regulating the spirit) and rehabilitation training and the simple treatment with rehabilitation training.@*METHODS@#A total of 60 patients with intestinal dysfunction of SCI were randomized into a comprehensive therapy group and a rehabilitation group, 30 cases in each one (3 cases were dropped out in each group). On the base of the routine western medicine treatment and rehabilitation training, the bowel training and rectal function training were provided, once a day in the rehabilitation group. In the comprehensive therapy group, on the base of the treatment as the rehabilitation group, the moxibustion was exerted at Yaoyangguan (GV 3), Mingmen (GV 4), Zhiyang (GV 9), Dazhui (GV 14) and Baihui (GV 20), etc, once a day, 30 min each time. In both groups, the treatment for 4 weeks was as one course and 3 courses of treatment were required. Separately, before treatment, after 4, 8 and 12 weeks of treatment, the scores of neurogenic bowel dysfunction (NBD) and World Health Organization quality of life scale (WHOQOL-BREF) were observed and the clinical effect was evaluated after 12 weeks of treatment.@*RESULTS@#After treatment, the total effective rate was 88.9% (24/27) in the comprehensive therapy group, which was higher than 74.1% (20/27) in the rehabilitation group (<0.05). After 4, 8 and 12 weeks of treatment, NBD scores were all reduced obviously as compared with those before treatment in the two groups (all <0.01). After 8 and 12 weeks of treatment, NBD scores in the comprehensive therapy group were lower than the rehabilitation group (both <0.05). After 4, 8 and 12 weeks of treatment, the scores of all of the domains (psychology, physiology, social relations and environment) in WHOQOL-BREF were higher than those before treatment in the two groups (all <0.01). After 4 weeks of treatment, the scores in the psychology and physiology domains in the comprehensive therapy group were higher than the rehabilitation group (all <0.05). After 8 and 12 weeks of treatment, the scores of all of the domains in the comprehensive therapy group were higher than the rehabilitation group (all <0.05).@*CONCLUSION@#The comprehensive treatment of moxibustion and rehabilitation training achieves the better effect on intestinal dysfunction of SCI than the simple rehabilitation training and greatly improves the quality of life in SCI patients.

OBJECTIVE@#To study the occurrence of serious adverse events (SAEs) related to chemotherapy with CCCG-ALL-2015 regimen in children with acute lymphoblastic leukemia (ALL) and the risk factors for death after the SAEs.@*METHODS@#A retrospective analysis was performed on the medical data of 734 children with ALL. They were treated with CCCG-ALL-2015 regimen from January 2015 to June 2019. The occurrence of SAEs during the treatment was investigated. The children with SAEs were divided into a death group with 25 children and a survival group with 31 children. A multivariate logistic regression analysis was used to analyze the risk factors for death after the SAEs.@*RESULTS@#Among the 734 children with ALL, 56 (7.6%) experienced SAEs (66 cases) after chemotherapy, among which 41 cases occurred in the stage of remission induction therapy. Of all 66 cases of SAEs, 46 (70%) were infection-related SAEs, including 25 cases of septic shock (38%), 20 cases of severe pneumonia (30%), and 1 case of severe chickenpox (2%), and 87% of the children with infection-related SAEs had neutrophil deficiency. The most common infection sites were blood and the lungs. The most common pathogens were Gram-negative bacteria, viruses, fungi, and Gram-positive bacteria. There were 16 cases (24%) of hemorrhage-related SAEs, with 11 cases of gastrointestinal bleeding (17%), 4 cases of pulmonary bleeding (6%), and 1 case of intracranial bleeding (2%). Of all 734 children with ALL, 66 (9.0%) died, among whom 25 died due to SAEs. The treatment-related mortality rate was 3.4%, and infection (72%) and bleeding (24%) were the main causes of death. Severe pneumonia was an independent risk factor for treatment-related death in ALL children (OR=4.087, 95%CI: 1.161-14.384, P=0.028).@*CONCLUSIONS@#SAEs often occur in the stage of remission induction therapy, and infection-related SAEs are more common in ALL children accepting chemotherapy with CCCG-ALL-2015 regimen. The development of severe pneumonia suggests an increased risk for death in these children.

Objective: The study was designed to assess the beneficial role of mangiferin (MGN) in lead (Pb)-induced neurological damages in the activation of Nrf2-governed enzymes, genes and proteins. Methods: A total of 96 weaned Wistar rats (48 males and 48 females, 26- to 27-day-old), weighing 50−80 g were used. The experiment was performed in six groups: normal group (control, n = 16), model group (chronic Pb exposed, n = 16), Dimercaptosuccinic acid (DMSA)-treated group (positive control, Pb + DMSA, n = 16), three MGN-treated groups with different doses (Pb + MGN, n = 48). Normal group freely had access to purified water. DMSA-treated group was given DMSA, which was clinically used as the standard treatment for moderate Pb poisoning, at 50 mg/kg (2 mL suspension with purified water) by intragastric gavage (ig) 4 continual days a week for 4 weeks, MGN-treated groups were given MGN at 50, 100, or 200 mg/kg (2 mL suspension with purified water) by ig daily for 4 weeks. At the end of the treatment, all rats were sacrificed and the brain samples were collected. The haematoxylin and eosin (H&E) staining was used for observation of histopathology. Commercial kit, real-time quantitative polymerase chain reaction (RT-qPCR), Western-blot and immunohistochemistry (IHC) detection were used to detect the mRNA and protein expression. Results: Eight weeks exposure to Pb-containing water resulted in pathological alterations, anti-oxidative system disorder in the brain, all of which were blocked by MGN in a Nrf2-dependent manner. Nrf2 downstream enzymes such as HO-1, NQO1, γ-GCS were activated. Nrf2, GCLC, GCLM, HO-1 mRNA and total Nrf2, Nuclear Nrf2, γ-GCS, HO-1 protein expression were affected too. Conclusion: MGN ameliorated morphological damage in the hippocampus. Its neuroprotective effects were achieved by the activation of the Nrf2 downstream genes. The data from this in vitro study indicates that MGN targeting Nrf2 activation is a feasible approach to reduce adverse health effects associated with Pb exposure. Thus, MGN could be an effective candidate agent for the Pb-induced oxidative stress and neurotoxicity in the human body.
