Abstract
Objective: To retrieve, evaluate, and summarize the best evidence for the treatment of hypoxemia in patients with COVID-19 infection using the awake prone positioning, with the aim of guiding healthcare professionals in the standardized implementation of this therapy. Methods: A systematic search was conducted in databases including UpToDate, BMJ Best Practice, JBI Evidence-Based Healthcare Center, American Association of Critical-Care Nurses, Intensive Care Society, European Respiratory Society, World Health Organization website, Cochrane Library, PubMed, China National Knowledge Infrastructure (CNKI), and Wanfang. The retrieved literature was subjected to quality assessment and evidence extraction. Results: A total of ten publications were included, consisting of one thematic evidence summary, one guideline, two systematic reviews, three randomized controlled trials, and three expert consensus statements. This summary synthesizes thirty key pieces of evidence in five categories: organizational management and training, risk assessment, preparatory operations, implementation key points, and risk control. Conclusions: Awake prone positioning is beneficial for improving hypoxemia in patients with COVID-19 and is easy to implement. Medical institutions should develop nursing management systems, operational standards, and best practices for awake prone positioning based on evidence-based evidence in order to improve the quality of care management for such patients.

Abstract
The dynamic progression of metabolic syndrome (MetS) includes developmental deterioration and reverse recovery; however, the key factors in this bidirectional progression have not been identified. Our study aimed to use the data obtained from the China Health and Retirement Longitudinal Study (CHARLS) and construct a Bayesian network to explore the causal relationship between influential factor and the development and recovery of MetS. Followed up at 4 years, forward progression of MetS occurred in 1543 and reverse recovery of MetS occurred in 1319 of 5581 subjects. Bayesian Networks showed that hyperuricemia and body mass index (BMI) levels directly influenced progression of MetS, and gender, exercise and age play an indirect role through hyperuricemia and BMI levels; high hemoglobin A1c (HbA1c) and BMI levels directly influenced recovery of MetS, and gender and exercise play an indirect role through BMI levels. Bayesian Network inference found that the rate of progression of MetS in subjects with hyperuricemia increases from 36 to 60%, the rate of progression of MetS in subjects with overweight or obese increases from 36 to 41% and the rate of reverse recovery rate of MetS in subjects with high HbA1c decreased from 33 to 20%. Therefore, attention to individuals at high risk of hyperuricemia, high HbA1c levels, and overweight/obesity should be enhanced, with early detection and following healthy behavioral interventions to prevent, control and delay the progression of MetS and its components.

Tunnel construction in shallow soft rock using the pipe shed support. Sci Rep 2024; 14:3401. [PMID: 38336812 PMCID: PMC10858042 DOI: 10.1038/s41598-024-53634-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Accepted: 02/03/2024] [Indexed: 02/12/2024] Open
Abstract
In order to clarify the impact mechanism of shallow buried soft rock tunnel excavation on the upper existing highway, as well as the mechanism of pipe shed reinforcement, a combination of theoretical analysis and on-site monitoring was used to conduct in-depth research on the Diantou Tunnel Crossing the existing highway project of Dayong Expressway. The impact of shallow buried soft rock tunnel crossing construction on the existing highway and safety control issues were studied, a new deformation control index, namely deformation difference rate, was introduced. The results show that the main lateral area of influence of rock deformation is within a distance of one diameter, and the overall area of influence is within a distance of twice the diameter. From the perspective of axial tunnel deformation, the deformation of surrounding rock tends to be stable when the excavation face passes through the monitoring section about twice the tunnel diameter. Effectively controlling rock deformation depends on the total amount of settlement deformation, the change rate of deformation, and the difference rate of deformation. For V-class shallow buried tunnel surrounding rock, in order to prevent cracks on the surface, the cumulative deformation of the surrounding rock needs to be less than 50 mm, the change rate needs to be less than 3 mm/day, and the difference rate needs to be less than 5 mm/m. Finally, the proposed control standard for surface subsidence is given for similar engineering reference.

Abstract
Myxobacteria have a complex life cycle and unique social behavior, and obtain nutrients by preying on bacteria and fungi in soil. Chitinase, β-1,3 glucanase and β-1,6 glucanase produced by myxobacteria can degrade the glycosidic bond of cell wall of some plant pathogenic fungi, resulting in a perforated structure in the cell wall. In addition, isooctanol produced by myxobacteria can lead to the accumulation of intracellular reactive oxygen species in some pathogenic fungi and induce cell apoptosis. Myxobacteria can also perforate the cell wall of some plant pathogenic oomycetes by β-1,3 glucanase, reduce the content of intracellular soluble protein and protective enzyme activity, affect the permeability of oomycete cell membrane, and aggravate the oxidative damage of pathogen cells. Small molecule compounds such as diisobutyl phthalate and myxovirescin produced by myxobacteria can inhibit the formation of biofilm and lipoprotein of bacteria, and cystobactamids can inhibit the activity of DNA gyrase, thus changing the permeability of bacterial cell membrane. Myxobacteria, as a new natural compound resource bank, can control plant pathogenic fungi, oomycetes and bacteria by producing carbohydrate active enzymes and small molecular compounds, so it has great potential in plant disease control.

Study on Quench Sensitivity during Isothermal Treatment of 7A65 Aluminum Alloy. MATERIALS (BASEL, SWITZERLAND) 2023; 17:193. [PMID: 38204046 PMCID: PMC10779591 DOI: 10.3390/ma17010193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Revised: 12/17/2023] [Accepted: 12/27/2023] [Indexed: 01/12/2024]
Abstract
The quenching sensitivity of 7A65 aluminum alloy was investigated using interrupted quenching experiments. The time-temperature transformation (TTT) and time-temperature performance (TTP) curves of the alloy were determined. The results indicate that the nose temperature is about 320 °C and the quenching sensitivity temperature range is from 240 °C to 360 °C. During the isothermal treatment, the supersaturated solid solution resolves to the equilibrium phase of η (MgZn2), and the precipitation rate is the largest at about 320 °C. Through transmission electron microscope (TEM) observation and X-ray diffraction (XRD) tests, it was found that with the extension of the isothermal holding time, the originally dispersed η' phase gradually decreases until disappear, and the number of η phase increases and gradually grows up at the grain boundary or around the Al3Zr particles. The rod-like η phase at the grain boundary is distributed from discontinuous distribution to chain-like continuous distribution, and the precipitation free zone (PFZ) is gradually generated and widened as the holding time is extended. At the nose temperature, the driving force of nucleation is high, and the diffusion rate is fast, which promotes the precipitation and growth of η phases. The coarse η phase weakens the mechanical properties. According to the results, it is recommended to increase the cooling rate at the sensitivity temperature range to reduce the precipitation of the η phase and decrease the quenching cooling rate from solution temperature to 360 °C to reduce residual stresses in the components.

Abstract
We studied the effect of TFP5 on MIN6 cells (cultured mouse islet β cells) treated with different concentrations of glucose (5 or 25 mM). The results were verified in C57BL/6J mice (control; n=12) and db/db mice with type 2 diabetes mellitus (n=12). To synthesize TFP5, peptide p5 (a derivative of p35 protein, activator of cyclin-dependent kinase 5, Cdk5) was conjugated with a FITC tag at the N-terminus and an 11-amino acid TAT protein transduction domain at the C-terminus. TFP5 was employed to inhibit Cdk5 activity and then to evaluate its efficiency in treating experimental type 2 diabetes mellitus. TFP5 effectively inhibited the pathological hyperactivity of Cdk5, enhanced insulin secretion, and protected pancreatic β cells from apoptosis in vitro and in vivo. In addition, TFP5 inhibited inflammation in pancreatic islets by reducing the expression of inflammatory cytokines TGF-β1, TNFα, and IL-1β. These novel data indicates that TFP5 is a promising candidate for treatment of type 2 diabetes mellitus.

Abstract
Objective: To compare the predictive efficacy of the two thrombosis risk assessment scores (Padua and IMPEDE scores) in venous thromboembolism (VTE) within 6 months in patients with newly diagnosed multiple myeloma (NDMM) in China. Methods: This study reviewed the clinical data of 421 patients with NDMM hospitalized in Beijing Jishuitan Hospital from April 2014 to February 2022. The sensitivity, specificity, accuracy, and Youden index of the two scores were calculated to quantify the thrombus risk assessment of VTE by the Padua and IMPEDE scores. The receiver operating characteristics curves of the two evaluation scores were drawn. Results: The incidence of VTE was 14.73%. The sensitivity, specificity, accuracy, and Youden index of the Padua score were 100%, 0%, 14.7%, and 0% and that of the IMPEDE score was 79%, 44%, 49.2%, and 23%, respectively. The areas under the curve of Padua and IMPEDE risk assessment scores were 0.591 and 0.722, respectively. Conclusion: IMPEDE score is suitable for predicting VTE within 6 months in patients with NDMM.

Abstract
AIM To evaluate the presentations of Müllerian duct anomalies (MDAs) associated with unilateral renal agenesis (URA) on magnetic resonance imaging (MRI). MATERIALS AND METHODS From 2014 to 2021, 92 patients with MDAs coexisting with URA who had undergone MRI were reviewed, and imaging patterns were analysed. RESULTS Based on the different imaging patterns, there were 74 cases of Herlyn-Werner-Wunderlich (HWW) syndrome (80.4%), nine cases of unicornuate uterus (10.9%), and nine cases of Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome (8.7%). In HWW syndrome, URA was ipsilateral to the vaginal or cervical obstruction. All the nine cases of unicornuate uterus were obstructive, and the most common subtype was unicornuate uterus with a non-communicating functioning rudimentary horn. The other two cases of unicornuate uterus with no rudimentary horn were obstructed due to cervical os obliteration, one of which was complicated with contralateral absent ovary. URA was contralateral to the unicornuate uterus in all cases. In MRKH syndrome, seven patients had bilateral rudiments and ovaries, all of which were unilaterally or bilaterally located above the pelvic brim, and URA was ipsilateral to the ectopic ovary in all cases. The other two patients had unilateral absent rudiment, ovary, and ipsilateral URA. CONCLUSIONS MRI presentations of URA-associated MDAs are diverse, with HWW syndrome being the most common form, followed by different patterns of unicornuate uterus and MRKH syndrome. An ectopic or absent ovary might be associated with URA in MRKH syndrome and unicornuate uterus.

Abstract
In nature, the production of plant stress resistance traits is often induced by extreme environmental conditions. Under extreme conditions, plants can be irreversibly damaged. Intervention with phytostimulants, however, can improve plant stress resistance without causing damage to the plants themselves, hence maintaining the production. For example, exogenous substances such as proteins and polysaccharides can be used effectively as phytostimulants. Chitooligosaccharide, a plant stimulant, can promote seed germination and plant growth and development, and improve plant photosynthesis. In this review, we summarize progress in the research of chitooligosaccharide-induced plant stress resistance. The mechanism and related experiments of chitooligosaccharide-induced resistance to pathogen, drought, low-temperature, saline-alkali, and other stresses are classified and discussed. In addition, we put forward the challenges confronted by chitooligosaccharide-induced plant stress resistance and the future research concept that requires multidisciplinary cooperation, which could provide data for the in-depth study of the effect of chitooligosaccharide on plants.

Abstract
Chitooligosaccharides (COS) with two different molecular weights are acylated with four nonpolar amino acids: glycine (Gly), alanine (Ala), valine (Val) and leucine (Leu) to obtain 2-aminoacetyl-chitooligosaccharide (2-GlyCOS), 2-aminopropionyl-chitooligosaccharide (2-AlaCOS), 2-amino-3-methylbutyryl-chitooligosaccharide (2-ValCOS), and 2-amino-4-methylpentanoyl-chitooligosaccharide (2-LeuCOS). The structure of the derivatives was characterized by FT-IR spectroscopy, 13C NMR spectroscopy, and elemental analysis. The antioxidant activities of the derivatives, such as hydroxyl radical (·OH) scavenging ability, superoxide anion (O2·-) scavenging ability, reducing ability, and DPPH radical scavenging ability, were investigated using various established systems. Compared with chitooligosaccharide and nonpolar amino acids, all derivatives have strong scavenging ability toward hydroxyl radicals and superoxide anions, and the clearance rate was 19.05% and 67.70% separately. The reducing ability and DPPH free radical scavenging ability of the derivatives are only 0.021Abs and 32.97%. Among them, only 2-AlaLCOS has significant reducing ability, and the value can reach 0.143Abs. The above results showed that the antioxidant activity of some derivatives was higher than that of chitooligosaccharide. The water solubility of the new derivatives was also greatly improved compared to that of nonpolar amino acids. Therefore, the application of 2-aminoacyl-chitooligosaccharides (2-AACOS) in antioxidants has laid a foundation and has certain potential application value in the fields of medicine, agriculture, and animal husbandry.

Abstract
PURPOSE Tuberculosis (TB) treatment is associated with Vitamin D. This study aimed to explore the relationship between Vitamin D receptor (VDR) gene polymorphisms and second acid-fast bacilli (AFB) smear-positive during treatment for TB patients. METHODS This was a cross-sectional study. Seven hundred and thirty-one TB patients whose single nucleotide polymorphism site (SNPs) of VDR gene were detected from December 2019 to December 2020 in XinJiang of China. The genotypic distributions in each group were tested separately for Hardy-Weinberg equilibrium. The tetragram test was used to construct haplotypes to evaluate the association between each haplotype and second AFB smear-positive occurrence. RESULTS No significant deviations were observed with all the four polymorphism sites in the genotypic distributions (P>0.05). Linkage disequilibrium (LD) analysis showed that there was LD between SNPs of VDR gene (r2=0.74, D`>0.9). Each haplotype was not considered to be the influencing factor of second AFB smear-positive. CONCLUSIONS There is no association between VDR gene polymorphism (ApaI, BsmI, FokI and TaqI) and second AFB smear-positive.

Abstract
Chitooligosaccharides with two different molecular weights are acylated with three containing benzene carboxylic acids: salicylic acid (BHA), α-naphthylacetic acid (NAA) and indole-3-butyric acid (IBA) to obtain o-hydroxybenzoyl-chitooligosaccharide, α-naphthylacetyl-chitooligosaccharide, and 3-Indolebutyryl-chitooligosaccharide. The structure of the derivatives was characterized by FT-IR spectroscopy, 13C NMR spectroscopy and elemental analysis. According to several amide characteristic absorption peaks between 1750 cm-1-1500 cm-1 in the FT-IR spectrum, it can be determined that the target group has been successfully grafted. And there are obvious characteristic absorption peaks of aromatic ring at 900-650 cm-1. The six chemical shifts of 98.02, 76.42, 74.83, 72.00, 60.39, 55.37 ppm in 13C NMR proved that the chitooligosaccharide did not destroy its own sugar ring structure during the reaction. The antioxidant activities of the derivatives, such as hydroxyl radical (·OH) scavenging ability, superoxide anion (O2·-) scavenging ability, reducing ability, and DPPH radical scavenging ability were investigated using various established systems. Comparing with chitooligosaccharide and containing benzene carboxylic acids, most derivatives have strong scavenging ability toward superoxide anions and DPPH radicals, and the clearance rate up to 47.44% and 80.27% separately. The reducing ability and hydroxyl free radical scavenging ability of the derivatives are only 0.032 Abs and 11.43%. The above results showed that the antioxidant activity of some derivatives was higher than that of chitooligosaccharide. The water solubility of the new derivatives was also greatly improved than that of containing benzene carboxylic acids. Therefore, the application of phenyl-acyl-chitooligosaccharide in antioxidants has laid a foundation, and has certain potential application value in the fields of medicine and agriculture and animal husbandry.

Abstract
OBJECTIVE The internal workings ofmachine learning algorithms are complex and considered as low-interpretation "black box" models, making it difficult for domain experts to understand and trust these complex models. The study uses metabolic syndrome (MetS) as the entry point to analyze and evaluate the application value of model interpretability methods in dealing with difficult interpretation of predictive models. METHODS The study collects data from a chain of health examination institution in Urumqi from 2017 ~ 2019, and performs 39,134 remaining data after preprocessing such as deletion and filling. RFE is used for feature selection to reduce redundancy; MetS risk prediction models (logistic, random forest, XGBoost) are built based on a feature subset, and accuracy, sensitivity, specificity, Youden index, and AUROC value are used to evaluate the model classification performance; post-hoc model-agnostic interpretation methods (variable importance, LIME) are used to interpret the results of the predictive model. RESULTS Eighteen physical examination indicators are screened out by RFE, which can effectively solve the problem of physical examination data redundancy. Random forest and XGBoost models have higher accuracy, sensitivity, specificity, Youden index, and AUROC values compared with logistic regression. XGBoost models have higher sensitivity, Youden index, and AUROC values compared with random forest. The study uses variable importance, LIME and PDP for global and local interpretation of the optimal MetS risk prediction model (XGBoost), and different interpretation methods have different insights into the interpretation of model results, which are more flexible in model selection and can visualize the process and reasons for the model to make decisions. The interpretable risk prediction model in this study can help to identify risk factors associated with MetS, and the results showed that in addition to the traditional risk factors such as overweight and obesity, hyperglycemia, hypertension, and dyslipidemia, MetS was also associated with other factors, including age, creatinine, uric acid, and alkaline phosphatase. CONCLUSION The model interpretability methods are applied to the black box model, which can not only realize the flexibility of model application, but also make up for the uninterpretable defects of the model. Model interpretability methods can be used as a novel means of identifying variables that are more likely to be good predictors.

[PMID: 35507601 PMCID: PMC9067663 DOI: 10.1371/journal.pone.0267917] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Accepted: 04/18/2022] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Vitamin D is related to human immunity, so we used Bayesian network model to analyze and infer the relationship between vitamin D level and the acid-fast bacilli (AFB) smear-positive after two months treatment among pulmonary tuberculosis (TB) patients. METHODS This is a cross-sectional study. 731 TB patients whose vitamin D level were detected and medical records were collected from December 2019 to December 2020 in XinJiang of China. Logistic regression was used to analyze the influencing factors of second AFB smear-positive. Bayesian network was used to further analyze the causal relationship among vitamin D level and the second AFB smear-positive. RESULTS Baseline AFB smear-positive (OR = 6.481, 95%CI: 1.604~26.184), combined cavity (OR = 3.204, 95%CI: 1.586~6.472), full supervision (OR = 8.173, 95%CI:1.536~43.492) and full management (OR = 6.231, 95%CI:1.031~37.636) were not only the risk factors and can also be considered as the reasons for second AFB smear-positive in TB patients (Ensemnle > 0.5). There was no causal relationship between vitamin D level and second AFB smear-positive (Ensemnle = 0.0709). CONCLUSIONS The risk factors of second AFB smear-positive were baseline AFB smear-positive, combined cavity, full supervision and full management. The vitamin D level in TB patients was not considered as one of the reasons for the AFB smear-positive.

Abstract
Background We aimed to construct simple and practical metabolic syndrome (MetS) risk prediction models based on the data of inhabitants of Urumqi and to provide a methodological reference for the prevention and control of MetS. Methods This is a cross-sectional study conducted in the Xinjiang Uygur Autonomous Region of China. We collected data from inhabitants of Urumqi from 2018 to 2019, including demographic characteristics, anthropometric indicators, living habits and family history. Resampling technology was used to preprocess the data imbalance problems, and then MetS risk prediction models were constructed based on logistic regression (LR) and decision tree (DT). In addition, nomograms and tree diagrams of DT were used to explain and visualize the model. Results Of the 25,542 participants included in the study, 3,267 (12.8%) were diagnosed with MetS, and 22,275 (87.2%) were diagnosed with non-MetS. Both the LR and DT models based on the random undersampling dataset had good AUROC values (0.846 and 0.913, respectively). The accuracy, sensitivity, specificity, and AUROC values of the DT model were higher than those of the LR model. Based on a random undersampling dataset, the LR model showed that exercises such as walking (OR=0.769) and running (OR= 0.736) were protective factors against MetS. Age 60 ~ 74 years (OR=1.388), previous diabetes (OR=8.902), previous hypertension (OR=2.830), fatty liver (OR=3.306), smoking (OR=1.541), high systolic blood pressure (OR=1.044), and high diastolic blood pressure (OR=1.072) were risk factors for MetS; the DT model had 7 depth layers and 18 leaves, with BMI as the root node of the DT being the most important factor affecting MetS, and the other variables in descending order of importance: SBP, previous diabetes, previous hypertension, DBP, fatty liver, smoking, and exercise. Conclusions Both DT and LR MetS risk prediction models have good prediction performance and their respective characteristics. Combining these two methods to construct an interpretable risk prediction model of MetS can provide methodological references for the prevention and control of MetS.

Evolution of MET and NRAS gene amplification as acquired resistance mechanisms in EGFR mutant NSCLC. NPJ Precis Oncol 2021; 5:91.

Abstract
EGFR mutant non-small cell lung cancer patients' disease demonstrates remarkable responses to EGFR-targeted therapy, but inevitably they succumb to acquired resistance, which can be complex and difficult to treat. Analyzing acquired resistance through broad molecular testing is crucial to understanding the resistance mechanisms and developing new treatment options. We performed diverse clinical testing on a patient with successive stages of acquired resistance, first to an EGFR inhibitor with MET gene amplification and then subsequently to a combination EGFR and MET targeted therapies. A patient-derived cell line obtained at the time of disease progression was used to identify NRAS gene amplification as an additional driver of drug resistance to combination EGFR/MET therapies. Analysis of downstream signaling revealed extracellular signal-related kinase activation that could only be eliminated by trametinib treatment, while Akt activation could be modulated by various combinations of MET, EGFR, and PI3K inhibitors. The combination of an EGFR inhibitor with a MEK inhibitor was identified as a possible treatment option to overcome drug resistance related to NRAS gene amplification.

Experimental study of land subsidence in response to groundwater withdrawal and recharge in Changping District of Beijing. PLoS One 2020; 15:e0232828.

Abstract
Over exploitation of groundwater in Changping District of Beijing city has caused serious land subsidence in the past decades. In recent years, the operation of the South-to-North Water Transfer Project has reduced the land subsidence rate. In this paper, Experimental tests are performed using the GDS Consolidation Testing System to characterize the compression and rebound of soils at depths of less than 100 m caused by groundwater withdrawal and recharge in Changping District. The results indicate that the compressible layers are the main contributors to land subsidence. The first compressible layer experiences greater deformation and more considerable hysteresis than the other compressible layers with the same decrease in the pore water pressure. Therefore, the exploitation of the adjacent aquifer should be controlled in the future. The deformation in the second and third compressible layers is a gradual and long-term process with little rebound; therefore, the subsidence should be seriously addressed when the groundwater in the two compressible layers is exploited on a large scale. In the same compressible layer, silty clay is more compressible and hysteretic than silt. For the same soil sample, the deformation rate decreases gradually as the pore water pressure decreases, whereas the creep deformation shows an overall increasing trend. A parameter named the subsidence index Cw is proposed in this paper to describe the soil compressibility during groundwater withdrawal. All the soil samples are characterized by elastic-plastic deformation, and the shallow soil samples with less pore water pressure decrease are more likely to rebound.

Abstract
Meniscus is a semilunar fibrocartilaginous tissue, serving important roles in load buffering, stability, lubrication, proprioception, and nutrition of the knee joint. The degeneration and damage of meniscus has been proved to be a risk factor of knee osteoarthritis. Mechanical stimulus is a critical factor of the development, maintenance and repair of the meniscus fibrochondrocytes. However, the mechanism of the mechano-transduction process remains elusive. Here we reported that cyclic hydrostatic compress force (CHCF) treatment promotes proliferation and inhibits apoptosis of the isolated primary meniscus fibrochondrocytes (PMFs), via upregulating the expression level of integrin α5β1. Consequently, increased phosphorylated-ERK1/2 and phosphorylated-PI3K, and decreased caspase-3 were detected. These effects of CHCF treatment can be abolished by integrin α5β1 inhibitor or specific siRNA transfection. These data indicate that CHCF regulates apoptosis of PMFs via integrin α5β1-FAK-PI3K/ERK pathway, which may be an important candidate approach during meniscus degeneration.

Abstract
Objective: To evaluate the efficacy and safety of Vesselplasty in the treatment of osteoporotic vertebral fractures and vertebral metastases. Methods: From June 2010 to December 2016, data of 81 patients with spinal diseases treated with Vesselplasty in Department of Spinal Surgery, Beijing Friendship hospital, Capital Medical University were retrospectively analyzed. There are 49 cases of vertebral fractures with age (70.2±8.2) years. Among them, 16 cases have posterior vertebral wall breakage, but no symptoms of nerve injury. Clinical result were evaluated with Visual Analogue Scale(VAS) , the kyphotic angle(Cobb's angle) and Oswestry disability index(ODI) was measured preoperatively, postoperatively and follow-up. At the same time, the operation time and cement leakage were recorded. There were 32 patients with vertebral metastases, with age of (69.6±11.1) years old. The posterior wall of the vertebral body was damaged in 22 cases. The VAS scores were recorded and compared preoperatively and postoperatively. The operation time was recorded also. Results: All patients were completed the operation safely and with no complications. Compared with preoperative VAS, postoperative VAS was significantly decreased in all subjects(P<0.05). The average operation time of each vertebral body was 16.2±4.6 min, and the postoperative VAS score significantly decreased (P<0.05), Cobb 's angle from preoperative (13.9±6.0) ° to( 5.2±4.0) ° (P<0.05) in 49 cases of vertebral fracture(58 vertebrae). The clinical results were still satisfied in follow-up . In 32 cases of vertebral metastases(38 vertebrae), the average operation time was (17.6±5.4) min. The postoperative VAS score was obviously decreased also(P<0.05). A small amount of bone cement leakage occurred in 4 cases of 4 vertebrae. The rate of bone cement leakage was 4.2%, but there were no clinical symptoms in these cases. Conclusion: Vesselplasty is a safe and effective treatment of osteoporotic vertebral fractures and vertebral metastases. It can lead to satisfactory clinical effect, partial recovery of vertebral height. Besides, the bone filling mesh can reduce the risk of bone cement leakage, which can provide a new choice for minimally invasive treatment of vertebral fracture and metastases.

Abstract
The division of stages on the formation and development of Mongolian medicine is a major issue on the history of Mongolian medicine. Based on Mongolian social, economic and cultural development and the characteristics of Mongolian medicine itself, Professor B. Jigmed creatively puts forward the three stages of development of ancient and modern times of Mongolian medicine. He also reasonably sorts out historical materials to comprehensively and systematically display the general picture of its development. This approach exerts great effect on restructuring the body of Mongolian medicine itself, unveils its rule of development, and promotes its disciplinary construction.

Abstract
BACKGROUND With the continuous improvement of liver transplantation technology, the survival rate of liver transplantation has been improved, but recurrent or de novo malignancy remains one of the major factors affecting the long-term survival of liver transplant recipients. CASE REPORT A 45-year-old Chinese man had a plastic biliary stent placed on account of biliary anastomotic stenosis after 3 years of piggyback liver transplantation. He came to our hospital because of recurrent fever and jaundice for 2 weeks, and his carcinoembryonic antigen-199 had increased. The patient's duodenal papillary was cauliflower-like at endoscopic retrograde cholangiopancreatography to replace the biliary stent. He was initially suspected of having duodenal papillary carcinoma after liver transplantation. However, the pathology from endoscopic retrograde cholangiopancreatography and endoscopic ultrasound-guided biopsy showed inflammation. While awaiting the result of biopsy, his CA-199 decreased significantly after anti-infection and symptomatic treatment. The patient was diagnosed with biliary anastomotic stenosis and duodenal papillitis. He was discharged uneventfully; to date, there is no evidence of malignant tumor. CONCLUSIONS We report this case to provide helpful information to clinicians about the management of the duodenal papilla cauliflower-like neoplasm after liver transplantation, which should be considered as inflammatory first. Perhaps our view can avoid the risk of bringing an excessive medical treatment and unnecessary economic burden to patients and their families.

Abstract
Primary splenic pregnancy is a rare type of ectopic pregnancy, which could easily rupture in the early stage of pregnancy, causing life-threatening intraabdominal haemorrhage. Rupture of splenic pregnancy due to trauma is even rarer. We reported a case of splenic pregnancy occurring in a female patient of reproductive age. She was injured by the handlebar on the upper left abdomen while riding a bicycle, causing intraabdominal haemorrhage. Ultrasound showed splenic rupture. The patient underwent emergency surgery, and was diagnosed with a rupture of splenic pregnancy by postoperative pathology. It is an extremely rare case where the patient was diagnosed splenic pregnancy due to a traumatic rupture and haemorrhage. We hope this case can be helpful in the evaluation and diagnosis of acute abdomen in women of reproductive age. (Hong Kong j.emerg.med. 2015;22:312-315)

Abstract
UNLABELLED In this meta-analysis, evidence of an association between type 2 diabetes mellitus (T2DM) and low-energy fractures has been evaluated including 12 observational studies. The results suggested that T2DM patients had an enhanced risk of low-energy fractures. INTRODUCTION Type 1 diabetes mellitus (T1DM) patients have been shown to be at enhanced risk of fracture injury, but less is known about low-energy fractures among patients with T2DM. METHODS We performed a meta-analysis of 12 observational studies identified in Medline and EMBASE that included 938,742 participants, including 30,827 low-energy fracture cases. The incidence rate ratios (IRRs) of low-energy fractures were determined using a random-effects model. RESULTS The IRRs of low-energy fracture for men and women were 1.37 (95% confidence interval [CI], 0.94-2.00; p = 0.096) and 1.22 (95% CI, 1.09-1.35; p = 0.000), respectively, and the overall IRR was 1.23 (95% CI, 1.12-1.35; p = 0.000). The IRRs for hip and vertebral fractures were 1.08 (95% CI, 1.02-1.15; p = 0.007) and 1.21 (95% CI, 0.98-1.48; p = 0.073), respectively. The IRRs of low-energy fracture in case-control, prospective, retrospective, and cross-sectional studies were 1.18 (95% CI, 0.81-1.72; p = 0.380), 1.17 (95% CI, 1.05-1.32, p = 0.006), 1.15 (95% CI, 1.02-1.29; p = 0.020), and 1.60 (95% CI, 1.21-2.12; p = 0.001), respectively. The IRRs of low-energy fracture for less than 5 years, 5 to 10 years, and more than 10 years were 1.30 (95%, CI 1.13-1.50; p = 0.000), 1.05 (95% CI, 1.03-1.08; p = 0.000), and 1.19 (95% CI, 1.00-1.41; p = 0.049), respectively. CONCLUSIONS Patients with T2DM had a greater risk of low-energy fracture especially of the hip, compared with that in non-diabetic subjects. However, since according to our funnel plot a publication bias may be present and due to study heterogeneity as well as the limited number of publications, the finding needs to be interpreted with caution.

Abstract
BACKGROUND Androgenetic alopecia (AGA), or male pattern baldness (MPB), is the most common form of hair loss in males. A combination of genetic and androgen causes have been suggested as factors that contribute to the development of AGA. However, the specific molecular mechanisms that underly AGA remain largely unknown. Long non-coding RNAs (lncRNAs), a new class of regulatory non-coding RNAs that are longer than 200 nucleotides, have been shown to play important roles in a number of cellular processes, including transcription, chromosome remodelling and post-transcriptional processing. The dysregulation of lncRNAs is associated with many forms of diseases, but it remains unknown whether lncRNAs are associated with AGA. OBJECTIVE The aim of this study was to identify AGA-associated lncRNAs and predict the potential roles of these lncRNAs in AGA. METHODS A genomewide microarray was used to identify lncRNAs that are differentially expressed between AGA and adjacent normal tissues. Real-time qRT-PCR was used to validate the microarray data. RESULTS A large number of lncRNAs were differentially expressed (fold change >2.4) between AGA and adjacent normal tissues. Of these, 770 were upregulated and 1373 were downregulated. Moreover, pathway analysis revealed that 53 functional pathways were associated with the upregulated transcripts, while 11 pathways were associated with the downregulated transcripts. CONCLUSION To our knowledge, this is the first study to investigate AGA-associated lncRNAs. lncRNA profiles are altered in AGA, and these lncRNAs and their target genes may serve as novel candidates for preventing and treating AGA.

Abstract
BACKGROUND The composition of ingested food is important for the gut microbiome and intestinal homeostasis. We have previously demonstrated that the structure and mechanical properties in the small intestine remodel significantly during fasting. However, it is not clear to what extent the intestinal mechanical properties changes when the composition of food is changed. This study aimed to investigate the passive biomechanical properties and intestinal tissue remodeling in rabbits fed a low-residue diet. METHODS New Zealand rabbits (control group n=6, intervention group n=7) were studied. Segments from duodenum, jejunum and ileum were excised. The intestinal diameter and length were obtained from digitized images of the segments at preselected luminal pressure levels and at no-load and zero-stress states. Circumferential and longitudinal stresses (force per area) and strains (deformation) were computed from the length, diameter and pressure data referenced to the zero-stress state geometry. Histomorphometric data were also obtained. KEY RESULTS The wet weight-per-unit length, wall thickness and wall area decreased in the intervention group (P<.05, P<.01). Histological measurement confirmed that the wall thickness decreased in all three segments, which was primarily due to mucosal thinning (P<.05). The opening angle tended to increase in all segments in the intervention group. Significant difference between the two groups was found for the jejunum (P<.05). Feeding the low-residue diet shifted the circumferential stress-strain curves in the intervention group to the right, indicating intestinal wall softening. CONCLUSIONS & INFERENCES Low-residue diet in rabbits for 1 month induces location-dependent histomorphometric and biomechanical remodeling of the intestine.

Abstract
Breast cancer, which derives from the epithelium of the mammary glands, is one of the most common cancers diagnosed in women globally. To date, the authors of many studies have reported that the deregulation of microRNAs (miRNAs) plays a crucial role in the occurrence, development, and metastasis of tumors. Here, we discovered that miR-660-5p was upregulated in the breast cancer cell lines MCF7 and MDA-MB-231 compared with that in the normal control cell line CCD-1095Sk. We then inhibited the expression of miR-660-5p to investigate its biological function in cancer development, progression, and metastasis. We determined the changes in the levels of expression of transcription factor CP2 (TFCP2) and CDKN1A to further clarify the specific mechanism involved. The results showed that downregulation of miR-660-5p significantly suppressed the proliferation, migration, and invasion of MCF7 breast cancer cell. Moreover, inhibition of miR-660-5p promoted cell cycle G1 arrest and reduced apoptosis in breast cancer cells. The specific mechanism studies confirmed that TFCP2 was a direct downstream target of miR-660-5p. Aberrant expression of miR-660-5p repressed TFCP2 expression, whereas inhibition of miR-660-5p decreased TFCP2 protein expression, which is a vital factor in the downstream signaling pathway. In conclusion, miR-660-5p can regulate the proliferation, migration, and invasion of human breast cancer cells, and is a novel potential therapeutic target for the clinical treatment of breast cancer.

Abstract
OBJECTIVE To observe the clinical characteristics of bone disease in patients with multiple myeloma (MM) and the clinical significance of monitoring bone metabolic markers. METHODS The data of 178 MM cases newly diagnosed in Beijing Ji Shui Tan Hospital from January 2009 to June 2014 were reviewed to analysis the types and classification of bone disease and to observe the clinical characteristics of patients with different grades of bone disease. The levels of bone metabolic markers total procollagen type Ⅰ N-terminal peptide (tPINP) and β C-terminal telopeptide of type Ⅰ collagen (β-CTX) were monitored regularly in the two years following treatment in 66 cases. RESULTS (1) Among the 178 newly diagnosed MM cases, 167 cases complained of pain in bones on first visit, 35 cases combined with hypercalcemia, 83 cases combined with osteoporosis, 154 cases combined with osteolytic bone destruction, and 73 cases combined with pathologic fracture. The most common osteolytic location was the spine. The most common fracture sites was the spine. (2) According to bone disease grading, the 178 cases were divided into group A (bone grade 0-2, n=51) and group B(bone grade 3-4, n=127). There were no significant differences between group A and group B in gender, median age, therapeutic effect/ineffec, median overall survival, median progress-free survival, mean serum lactic dehydrogenase, mean albumin, urine light chains and serum creatinine(all P>0.05). Compared with group A, group B had lower hemoglobin level[(99.78±29.93)vs (108.84±29.30) g/L], and higher blood calcium level[(2.47±0.40)vs (2.30±0.29) mmol/L], serum β2-microglobuin level[(6.04±4.84)vs (4.12±3.97)mg/L], and bone marrow plasma cells percentage(33.30%±24.87% vs 23.51%±22.67%)(all P<0.05). (3) Before treatment, the levels of β-CTX and tPINP in patients of group B(n=47) were higher than those in group A(n=19)(median 0.78 vs 0.42 μg/L, 60.95 vs 43.47 μg/L, both P<0.05). The ratio of β-CTX /tPINP in group B was higher than that in group A (median 0.017 vs 0.012, P<0.05). After chemotherapy for 3 months, there were no differences in the level of tPINP compared with that before treatment in both group A and group B (both P>0.05), the level of β-CTX decreased significantly compared with that before treatment in both groups(median 0.16 vs 0.42 μg/L, 0.26 vs 0.78 μg/L, both P<0.05); the ratio of β-CTX /tPINP decreased significantly compared with that before treatment in both group A and in group B(median 0.008 vs 0.012, 0.011 vs 0.017, both P<0.05). There were no differences in the level of β-CTX, tPINP and β-CTX/tPINP ratio after treatment for 6 months, 1 year and 2 years compared with that after 3 months in both group A and group B (all P>0.05). (4)All patients were divided into two groups according to the therapeutic effect: effective group included patients who reach the effect of partial remission or better remission(n=48), while ineffective group included patients who did not reach the effect of partial remission(n=18). Before treatment there were no differences in the level of β-CTX, tPINP and β-CTX/tPINP ratio between the effective groupand the ineffective group (all P>0.05). After chemotherapy for 3 months, there were no differences in the level of tPINP compared with that before treatment in both effective group and ineffective group (all P>0.05), but the level of β-CTX decreased significantly compared with that before treatment both in effective group and ineffective group (median 0.24 vs 0.60 μg/L, 0.44 vs 0.95 μg/L, both P<0.05). The ratio of β-CTX /tPINP decreased significantly compared with that before treatment both in effective group and ineffective group (median 0.005 vs 0.012, 0.005 vs 0.011, both P<0.05). There were no differences in the level of β-CTX, tPINP and β-CTX/tPINP ratio after treatment for 6 months, 1 year and 2 years compared with that for 3 months both in effective group and ineffective group (all P>0.05). CONCLUSIONS Pain in bones, osteolysis and pathological fracture are the most common clinical manifestations in myeloma-related bone disease. The severity of bone disease can reflect the tumor load, but may not affect the therapeutic effect and the overall survival. The bone metabolic markers tPINP and β-CTX can be used to evaluate the severity of myeloma-related bone disease at diagnosis and to monitor the effect of treatment for bone disease.

Abstract
OBJECTIVE To investigate the prognostic significance of proportion of the blasts in bone marrow on day 14 (D14) during induction chemotherapy in patients with adult Ph-negative acute lymphoblastic leukemia (Ph (-) ALL). METHODS Newly diagnosed Ph (-) ALL patients with bone marrow morphology analysis on day 14 during induction chemotherapy were analyzed retrospectively. The proportion of the D14 blasts which had an impact on achieving a CR by the first induction chemotherapy and outcomes were determined by ROC curve. RESULTS 166 ALL patients including 94 male and 72 female were analyzed. The median age was 32 years (range, 18-64 years). The CR rate by the first induction chemotherapy was 74.7% with a total CR rate as 93.3%. By ROC analysis, 7.5% of the D14 blasts had the best sensitivity and specificity. The patients with D14 blasts ≥7.5% had lower CR rates after the first and overall induction chemotherapy compared with those with D14 blasts <7.5% (42.7% vs 85.9%, P<0.001 and 75.9% vs 95.6%, P=0.001 respectively). The probabilities of 5-year disease free survival (DFS) and 5-year overall survival (OS) were higher in the patients with D14 blasts<7.5% than those with D14 blasts ≥7.5% (49.8% vs 29.6%, P=0.006 and 52.4% vs 32.6%, P=0.010 respectively). Multivariate analysis showed that higher WBC or central nervous system leukemia at diagnosis, D14 blasts ≥7.5%, no CR after the first induction chemotherapy and receiving consolidation and maintenance chemotherapy rather than transplant were associated with poor outcomes. CONCLUSIONS Higher proportion of D14 blasts in bone marrow during the first induction therapy indicated poor prognosis in adult Ph(-) ALL.

[Comparison of efficacy and prognostic factors in elderly acute myelogenous patients with MA or CAG induction chemotherapy regimen]. ZHONGHUA XUE YE XUE ZA ZHI = ZHONGHUA XUEYEXUE ZAZHI 2016; 37:194-200. [PMID: 27033755 PMCID: PMC7342949 DOI: 10.3760/cma.j.issn.0253-2727.2016.03.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/26/2015] [Indexed: 11/26/2022]
Abstract
OBJECTIVE To analyze the difference of efficacy and prognostic factors between MA and CAG induction chemotherapy in elderly acute myelogenous leukemia (AML) patients. METHODS From April 2009 to September 2015, 103 consecutive hospitalized 60-plus-year-old AML patients were retrospectively analyzed. NPM1 positive FLT3-ITD negative accounted for 17 cases (16.7%). Sixty-five patients received MA regimen and thirty-eight patients received CAG regimen. MA group had higher WBC and FLT3-ITD positive mutations at diagnosis compared with CAG group (P=0.001, P=0.005; respectively). The median follow-up was 13 months for all patients and 17 months for the survivors. RESULTS Six patient (5.8%) died in early phase. Complete remission (CR) rate after the first cycle of induction chemotherapy was 51.5% (50/97). Overall CR rate was 70.1% (68/97). CR rate after the first cycle of induction chemotherapy and overall CR rate were indiscriminate between MA and CAG regimen. The time to neutrophil count recovery, the time to platelet count recovery and the number of platelet transfusions were indiscriminate between MA and CAG regimen. Among 68 CR patients, 23 patients relapsed at median 9 months, and cumulative incidence of relapse (CIR) at 3 years was (52.5±10.1)%. Median overall survival (OS) was 20 months. OS rate at 3 years was 32.2%. Median disease-free survival (DFS) was 28 months. DFS rate at 3 years was 43.7%. CIR, DFS and OS at 3 years were indiscriminate between MA and CAG regimen. Multivariate analysis showed that less than 70 years of age (P=0.001), achieved CR (P<0.001), and NPM1 (+) FLT3-ITD(-) mutation (P=0.044) were the independent factors for increasing OS. NPM1(+) FLT3-ITD(-) mutation was the independent factor for increasing DFS (P=0.042). Patients were classified by three prognosis factors: <70 ages, CR, and NPM1(+)FLT3-ITD(-) mutation. Patients with no poor prognosis factors were classified as low risk (n=13), with one factor as medium risk (n=52) and with two and more factors as high risk (n=31). There were significant differences in OS rate and DFS rate at 3 years for 3 groups patients (60.5% vs 48.1% vs 0, P<0.001; 60.2% vs 39.4% vs 0, P=0.045; respectively). OS and DFS at 3 years for 3 groups' patients were indiscriminate between MA and CAG regimen. CONCLUSIONS There was indiscrimination of efficacy among MA and CAG induction chemotherapy in old AML patients. Less than 70 years of age, CR and NPM1(+)FLT3-ITD(-) mutation were the independent factors for better survival.
