ABSTRACT

OBJECTIVE@#To investigate humanistic practice ability of nurses in a general hospital in Hunan Province and analyze the factors affecting their practices to provide evidence for interventions to improve humanistic practice ability of the nurses.@*METHODS@#A total of 1196 nurses were surveyed using a self-designed questionnaire and a nurse humanistic practice ability assessment scale questionnaire for assessment of their abilities for humanistic care practice, psychological adjustment, interpersonal communication, self-management, ethics and legal practice. Univariate and multivariate analyses were performed for analysis of the factors affecting the practice abilities of the nurses.@*RESULTS@#The total score of humanistic practice ability of the 1196 nurses was 105.69±16.45 (the full score of the scale was 130), and the scores of humanistic care practice ability, psychological adjustment ability, interpersonal communication ability, self-management ability, ethics and legal practice ability were 40.95±6.46, 16.41±2.66, 16.41±2.66, 11.32±2.05 and 12.43±2.00, respectively. Univariate analysis and multiple linear regression analysis showed that gender (P=0.033), age (P < 0.001), department (P=0.015), working years (P < 0.001), professional title (P < 0.001), first academic degree (P < 0.001), highest academic degree (P < 0.001), family location (P=0.010), marital status (P=0.023), number of patients to care for (P=0.022), number of children (P=0.001), previous humanities related training (P < 0.001), training times (P < 0.001), and care received from family members (P < 0.001) and colleagues (P < 0.001) were all the factors affecting humanistic practice ability of the nurses. Among these factors, age, working in department of obstetrics and gynecology and emergency department, professional title, humanities training, and care from family and colleagues explained 20.7% of the variance.@*CONCLUSION@#The humanistic practice ability of nurses in this general hospital is above the average level, but their self-management ability needs to be improved. Intervention measures should be implemented to improve the nurses' humanistic practice ability including more attentions to the key groups and departments, strengthening the training of humanistic practice ability, and improving the promotion assessment system.

ABSTRACT

In order to comprehensively evaluate the quality of Viticis Fructus, this study established HPLC fingerprints and evaluated the quality of 24 batches of Viticis Fructus samples from different species by similarity evaluation and multivariate statistical analysis(PCA, HCA, PLS-DA). On this basis, an HPLC method was established to compare the content differences of the main components, including casticin, agnuside, homoorientin, and p-hydroxybenzoic acid. The analysis was performed on the chromatographic column(Waters Symmetry C_(18)) with a gradient mobile phase of acetonitrile(A)-0.05% phosphoric acid solution(B) at the flow rate of 1 mL·min~(-1) and detection wavelength of 258 nm. The column temperature was 30 ℃ and the injection volume was 10 μL. The HPLC fingerprint of 24 batches of Viticis Fructus samples was established with 21 common peaks, and nine peaks were identified. Similarity analysis was carried out based on chromatographic data of 24 batches of chromatographic data of Viticis Fructus, and the results showed that except for DYMJ-16, the similarity of Vitex trifolia var. simplicifolia was ≥0.900, while that of V. trifolia was ≤0.864. In addition, the similarity analysis of two different species showed that the similarity of 16 batches of V. trifolia var. simplicifolia was 0.894-0.997 and that of the eight batches of V. trifolia was between 0.990 and 0.997. The results showed that the similarity of fingerprints of these two species was different, but the similarity between the same species was good. The results of the three multivariate statistical analyses were consistent, which could distinguish the two different species. The VIP analysis results of PLS-DA showed that casticin and agnuside contributed the most to the distinction. The content determination results showed that there was no significant difference in the content of homoorientin and p-hydroxybenzoic acid in Viticis Fructus from different species, but the content of casticin and agnuside was significantly different in different species(P<0.01). The content of casticin was higher in V. trifolia var. simplicifolia, while agnuside was higher in V. trifolia. The findings of this study show that there are differences in fingerprint similarity and component content of Viticis Fructus from different species, which can provide references for the in-depth study of the quality and clinical application of Viticis Fructus.

ABSTRACT

This study aims to investigate the expression, prognosis, and clinical significance of C5orf46 in gastric cancer and to study the interaction between the active components of C5orf46 and tarditional Chinese medicine. The ggplot2 package was utilized for differential expression analysis of C5orf46 in gastric cancer tissues and normal tissues. The survival package was used for survival analysis, univariate regression analysis, and multivariate regression analysis. Nomogram analysis was used to assess the connection between C5orf46 expression in gastric cancer and overall survival. The abundance of tumor-infiltrating lymphocytes was calculated by GSVA package. Coremine database, Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) database, and PubChem database were used to search the potential components corresponding to C5orf46 gene and tarditional Chinese medicine. Molecular docking was performed to explore the binding affinity of potential components to C5orf46. Cell experiments were performed to explore the expression of C5orf46 gene in cells of the blank group, model group, and drug administration groups. As compared with normal tissues, C5orf46 expression was higher in gastric cancer tissues, which had more significant predictive effects in the early stages(T2, N0, and M0). The more advanced the tumor node metastasis(TNM) stage, the higher the C5orf46 expression and the lower the probability of survival of patients with gastric cancer. The expression of C5orf46 positively correlated with the helper T cells1 in gastric cancer and the macrophage infiltration level in gastric cancer, and negatively correlated with B cells, central memory T cells, helper T cells 17, and follicular helper T cells. Seven potential components of C5orf46 were obtained, and three active components were obtained after the screening, which matched five tarditional Chinese medicines, namely, Sojae Semen Nigrum, Jujubae Fructus, Trichosanthis Fructus, Silybi Fructus, and Bambusae Concretio Silicea. Molecular docking revealed that sialic acid and adeno-sine monophosphate(AMP) had a good binding ability to C5orf46. The results of real-time quantitative polymerase chain reaction(RT-qPCR) and Western blot showed that, as compared with the model group, the mRNA and protein expression levels of C5orf46 were significantly lower in the drug administration groups. The lowest expression level was found at the concentration of 40 μmol·L~(-1). The results of this study provide ideas for the clinical development of traditional Chinese medicine compounds for the treatment of gastric cancer as well as other cancers.

ABSTRACT

Pellionia scabra belongs to the genus Pellionia in the family of Urticaceae, and is a high-quality wild vegetables with high nutritional value. In this study, high-throughput techniques were used to sequence, assemble and annotate the chloroplast genome. We also analyzed its structure, and construct the phylogenetic trees from the P. scabra to further study the chloroplast genome characteristics. The results showed that the chloroplast genome size was 153 220 bp, and the GC content was 36.4%, which belonged to the typical tetrad structure in P. scabra. The chloroplast genome encodes 130 genes, including 85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes in P. scabra. Among them, 15 genes contained 1 intron, 2 genes contained 2 introns, and rps12 had trans-splicing, respectively. In P. scabra, chloroplast genomes could be divided into four categories, including 43 photosynthesis, 64 self-replication, other 7 coding proteins, and 4 unknown functions. A total of 51 073 codons were detected in the chloroplast genome, among which the codon encoding leucine (Leu) accounted for the largest proportion, and the codon preferred to use A and U bases. There were 72 simple sequence repeats (SSRs) in the chloroplast genome of P. scabra, containing 58 single nucleotides, 12 dinucleotides, 1 trinucleotide, and 1 tetranucleotide. The ycf1 gene expansion was present at the IRb/SSC boundary. The phylogenetic trees showed that P. scabra (OL800583) was most closely related to Elatostema stewardii (MZ292972), Elatostema dissectum (MK227819) and Elatostema laevissimum var. laevissimum (MN189961). Taken together, our results provide worthwhile information for understanding the identification, genetic evolution, and genomics research of P. scabra species.

ABSTRACT

Heart failure with preserved ejection fraction (HFpEF) is a type of heart failure characterized by left ventricular diastolic dysfunction with preserved ejection fraction. With the aging of the population and the increasing prevalence of metabolic diseases, such as hypertension, obesity and diabetes, the prevalence of HFpEF is increasing. Compared with heart failure with reduced ejection fraction (HFrEF), conventional anti-heart failure drugs failed to reduce the mortality in HFpEF due to the complex pathophysiological mechanism and multiple comorbidities of HFpEF. It is known that the main changes of cardiac structure of in HFpEF are cardiac hypertrophy, myocardial fibrosis and left ventricular hypertrophy, and HFpEF is commonly associated with obesity, diabetes, hypertension, renal dysfunction and other diseases, but how these comorbidities cause structural and functional damage to the heart is not completely clear. Recent studies have shown that immune inflammatory response plays a vital role in the progression of HFpEF. This review focuses on the latest research progress in the role of inflammation in the process of HFpEF and the potential application of anti-inflammatory therapy in HFpEF, hoping to provide new research ideas and theoretical basis for the clinical prevention and treatment in HFpEF.

ABSTRACT

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.

ABSTRACT

OBJECTIVE Epilepsy is considered a cir-cuit-level dysfunction associated with imbalanced excita-tion-inhibition,it is therapeutically necessary to identify key brain regions and related circuits in epilepsy.The subic-ulum is an essential participant in epileptic seizures,but the circuit mechanism underlying its role remains largely elusive.METHODS Here we deconstruct the diversity of subicular circuits in mouse models of epilepsy.Fiber pho-tometry was used to detect intrinsic activities of subicular PV,SST-positive interneurons and CaMK Ⅱ α-positive pyramidal neurons.Optogenetics and chemogenetics were used to selectively active or inactive subicular neu-rons or their projecting terminals.We also used in vivo and in vitro electrophysiology to record membrane charac-teristics of single neuron in distinct sub-regions of the subiculum.Finally,single pulse test was used to detect synaptic transmission strength between the subiculum and its downstream target.RESULTS First,we found that two majority of subicular interneurons,which inner-vate local pyramidal neurons to constrain their excitability,PV and SST-positive neurons showcase distinct calcium dynamics during hippocampal seizures.This could be attributed to distinct neural inputs from para-hippocampal regions of these two neuronal types.During epileptogen-esis,PV and SST neurons undergo different circuit reor-ganization patterns,that is,remarkable increase of exter-nal input to subicular PV neurons are seen after seizures,while SST cells receive decimated neural input.As their downstream targets,excitatory subicular pyramidal neu-rons are also intrinsically activated during hippocampal seizures.Moreover,we found that the subiculum hetero-geneously controls the generalization of hippocampal sei-zures by projecting to different downstream regions.No-tably,anterior thalamus projecting subicular neurons bidi-rectionally mediate seizures,while entorhinal cortex-pro-jecting subicular neurons act oppositely in seizure modu-lation.These two subpopulations are structurally and functionally dissociable.An intrinsically enhanced hyper-polarization-activated current and robust bursting intensity in anterior thalamus-projecting neurons facilitate synaptic transmission,thus contributing to the generalization of hippocampal seizures.CONCLUSION These results demonstrate that subicular neurons and circuits have diverse roles in epilepsy,suggesting the necessity to pre-cisely target specific subicular circuits for effective treat-ment of epilepsy.

ABSTRACT

Purpose@#This study aimed to explore the impact of ABL1–tyrosine kinase inhibitors (TKIs) adherence on the survival of chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) children and clarify the potential predictors of patients’ prognosis from TKIs intake practices. @*Materials and Methods@#Ninety newly diagnosed Ph+ ALL patients who received TKIs were enrolled. We collected the baseline characteristics and adverse events in all children; moreover, TKIs adherence was measured by an eight-item Morisky medication adherence scale (MMAS-8). Progression-free survival (PFS) and overall survival (OS) analysis were performed, and risk factors for PFS and OS were evaluated. @*Results@#Among all patients, 69 cases were regarded as adherers, while 21 were non-adherers. The median duration of TKIs interruption was significantly prolonged in the non-adherence group than in the adherence group (13 [0-101] vs. 56 [11-128], p < 0.001). Additionally, dose reduction occurred in 55.2% of non-adherers versus 23.0% of adherers (p=0.002). The PFS and OS in adherers were significantly higher versus non-adherers (p=0.020 and p=0.039). MMAS-8 score was an independent risk factor for PFS (p=0.010) and OS (p=0.031). Among non-adherers, the median OS was only 23.1% (4.2%-42%) in patients aged ≤ 10 years versus 54.4% (38.8%-70%) in adolescents. Most of the patients who experienced TKIs non-adherence suffered pancytopenia. @*Conclusion@#TKIs adherence during treatment significantly influenced the survival of pediatric Ph+ ALL patients, and non-adherers with age ≤ 10 years were more vulnerable to TKIs disruption. The cumulative TKIs dose should be especially emphasized to patients with age ≤ 10 years, which may result in an inferior achievement of relevant treatment milestones.

ABSTRACT

This study focuses on the microbial quality control of the Chinese herbal decoction pieces. In view of the shortcomings of traditional culture methods such as slow detection speed and inability to detect unculturable microorganisms, a new method based on ATP bioluminescence technology combined with statistical analysis methods was established to rapidly predict and quantitatively detect the total aerobic microbial count (TAMC) and total yeast and mold count (TYMC) contaminated Bupleurum chinense DC. decoction pieces. Based on the optimized ATP bioluminesence detection system, accurate detection of pure bacterial solution of Escherichia coli, Bacillus subtilis and Staphylococcus aureus can be achieved, with detection limits of 47.86, 89.13 and 1 862.09 CFU·mL-1, respectively. The detection time was 6.5 h, and the detection cost was as low as 2 yuan/time. The upper and lower warning limits of TAMC were determined by the misjudgment rates of 10% and 20%, respectively. And the warning limit of TYMC was determined by the misjudgment rate of 20%. The proposed crossing method could quickly predict the amount of microbial contamination in Bupleurum chinense DC. decoction pieces. The constructed partial least squares regression (PLSR) model could accurately quantify the quantity of microbial contamination in Bupleurum chinense DC. decoction pieces. The optimal PLSR prediction model for TAMC had a correction coefficient (R2) of 0.826, a root mean square error of correction set (RMSEE) of 0.468 and a root mean square error of cross-validation set (RMSECV) of 0.465. The R2, RMSEE and RMSECV in the prediction model of TYMC were 0.778, 0.543 and 0.541, respectively. The aim of this study is to establish a kind of rapid detection method and prediction models for the microbial limit of traditional Chinese medicine and Chinese herbal decoction pieces, and to provide a more convenient and sensitive detection technology for the microbial quality process control of traditional Chinese medicine products.

ABSTRACT

The purpose of this study was to establish a suitable method for extracting cerebrospinal fluid (CSF) from C57BL/6 mice. A patch clamp electrode puller was used to draw a glass micropipette, and a brain stereotaxic device was used to fix the mouse's head at an angle of 135° from the body. Under a stereoscopic microscope, the skin and muscle tissue on the back of the mouse's head were separated, and the dura mater at the cerebellomedullary cistern was exposed. The glass micropipette (with an angle of 20° to 30° from the dura mater) was used to puncture at a point 1 mm inboard of Y-shaped dorsal vertebral artery for CSF sampling. After the first extraction, the glass micropipette was connected with a 1 mL sterile syringe to form a negative pressure device for the second extraction. The results showed that the successful rate of CSF extraction was 83.33% (30/36). Average CSF extraction amount was (7.16 ± 0.43) μL per mouse. In addition, C57BL/6 mice were given intranasally ferric ammonium citrate (FAC) to establish a model of brain iron accumulation, and the CSF extraction technique established in the present study was used for sampling. The results showed that iron content in the CSF from the normal saline control group was not detected, while the iron content in the CSF from FAC-treated group was (76.24 ± 38.53) μmol/L, and the difference was significant. These results suggest that glass micropipette vacuum technique of CSF sampling established in the present study has the advantages of simplicity, high success rate, large extraction volume, and low bleeding rate, and is suitable for the research on C57BL/6 mouse neurological disease models.

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

Objective:This study aimed to investigate the present status of professional identity in internship nursing students and to find the moderate role of mindfulness in the relationship between neuroticism and professional identity.Methods:This was a cross sectional investigation. From October to December 2021, 819 internship nursing students from four hospitals of Shandong Province were invited to participate in the study and to finish a questionnaire survey including the general information questionnaire, Professional Identity Questionnaire for Nurse Students (PIQNS), the Big Five Inventory(BFI) and Mindful Attention Awareness Scale (MAAS).Results:The average score of PIQNS was (61.41 ± 11.59). Pearson correlation analysis showed that professional identity was negatively associated with neuroticism ( r=-0.405, P<0.01) and positively associated with mindfulness ( r=0.301, P<0.01). Neuroticism was negatively associated with mindfulness ( r=-0.439, P<0.01). The hierarchical regression showed that mindfulness level could moderate the correlation between neuroticism and professional identity. Furthermore, the Johnson-Neyman technique revealed that the moderating role was significant only when the positive level was greater than 47.085. Conclusions:The professional identity of internship nursing students deserves attention. Mindfulness level could moderate the correlation between neuroticism and professional identity. It is suggested that clinical managers to carry out targeted training, to enhance the professional identity of internship nursing students during internship.

ABSTRACT

A retrospective case review was conducted of 3 cases with umbilical venous catheterization(UVC) related pericardial effusions in the Neonatal Intensive Care Unit of Zhongnan Hospital of Wuhan University from December 2020 to April 2022.All 3 cases were preterm infants with gestational ages of 33 + 4, 31 and 27 + 6 weeks, respectively.UVC was inserted routinely in 24 hours after birth.Three neonates developed tachycardia or bradycardia, dyspnea, decreased oxygen saturation and muffled heart sound at the 1 st to 4 th day after catheterization.Echocardiography indicated pericardial effusion, so the 3 neonates underwent pericardiocentesis and drainage.Among the 3 neonates, 2 cases improved and have good prognosis, 1 case died.UVC can cause pericardial effusion, which occurs mostly in the early stage after catheterization.Pericardial effusion and tamponade should be considered when patients show unexplained sudden clinical deterioration after catheterization, such as dyspnea, cyanosis, tachycardia or bradycardia, etc.Once diagnosed, umbilical vein catheter should be removed in time and pericardiocentesis and drainage should be performed for decompression.Early diagnosis and intervention can effectively improve the prognosis.

ABSTRACT

AIM: To evaluate the clinical effect of 25G pars plana vitrectomy(PPV)combined with dexamethasone intravitreal implant(DEX)on the treatment of vitreous hemorrhage and diabetic macular edema(DME)secondary to proliferative diabetic retinopathy(PDR).METHODS: Prospective clinical case study. A total of 40 patients(40 eyes)with vitreous hemorrhage and DME secondary to PDR who treated in Tianjin Eye Hospital from July 2020 to January 2022 were included in the study. All eyes underwent 25G PPV and cataract phacoemulsification. The patients were randomly divided into PPV group(20 eyes)and PPV+DEX group(20 eyes). Best corrected visual acuity(BCVA), intraocular pressure, and central macular thickness(CMT)of the patients before and 1, 3, 6mo after the operation were compared.RESULTS: All patients were followed up for 6mo. The BCVA of the patients in the PPV+DEX group improved better than that of the PPV group at 1, 3 and 6mo after surgery(P&#x003C;0.05). CMT of the PPV+DEX group was lower than that of the PPV group at 1mo after operation(P&#x003C;0.05). Retinal neovascularization or CMT regression with less than 5% was found in 8 eyes in the PPV group, who were supplemented with anti-vascular endothelial growth factor, while it was found in only 1 eye in the PPV+DEX group(P&#x003C;0.05).CONCLUSION: PPV combined with DEX could yield synergies, which provide better therapeutic effect for the patients with vitreous hemorrhage and DME secondary to PDR.

ABSTRACT

With the increasing number of obese patients worldwide, metabolic and bariatric surgery (MBS) has quickly become an effective way to treat obesity and related metabolic diseases such as type 2 diabetes, hypertension, lipid abnormalities, etc. Although MBS has become an important part of general surgery, there is still controversy regarding the indications for MBS. In 1991, the National Institutes of Health (NIH) issued a statement on the surgical treatment of severe obesity and other related issues, which continues to be the standard for insurance companies, health care systems, and hospital selection of patients. The standard no longer reflects the best practice data and lacks relevance to today's modern surgeries and patient populations. After 31 years, in October 2022, the American Society for Metabolic and Bariatric Surgery (ASMBS) and the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO), the world's leading authorities on weight loss and metabolic surgery, jointly released new guidelines for MBS indications, based on increasing awareness of obesity and its comorbidities and the accumulation of evidence of obesity metabolic diseases. In a series of recommendations, the eligibility of patients for bariatric surgery has been expanded. Specific key updates include the following: (1) MBS is recommended for individuals with BMI≥35 kg/m2, regardless of the presence, absence, or severity of co-morbidities; (2) MBS should be considered for individuals with metabolic diseases and BMI 30.0-34.9 kg/m2; (3) the BMI threshold should be adjusted for the Asian population:: BMI≥25 kg/m2 suggest clinical obesity, and BMI ≥ 27.5 kg/m2 population should consider MBS; (4) Appropriately selected children and adolescents should be considered for MBS.

ABSTRACT

Objective: To investigate and understand the medical security and quality of life of migrant workers with pneumoconiosis, so as to provide scientific basis for the prevention and control countermeasures of migrant workers with pneumoconiosis and targeted poverty alleviation. Methods: Using a stratified random sampling method, 200 migrant workers diagnosed with pneumoconiosis at the Shandong Academy of Occupational Health and Occupational Medicine from January 2016 to December 2021 were selected as the observation group, while 200 non migrant workers diagnosed with pneumoconiosis were selected as the control group. St. George's Respiratory Questionnaire (SGRQ) and Pneumoconiosis Questionnaire were used to collect and compare information on the age, working age of dust exposure, economic sources, employment status, income, medical security and quality of life of two groups of patients. Results: The age of migrant worker pneumoconiosis patients in the observation group was (58.1±8.1) years old, and the working age of dust exposure was (19.3±10.1) years. The main source of income was children support (85.5%, 171/200), employment status was mainly wait for employment or unemployed (69.0%, 138/200), personal monthly income was mainly non income (90.0%, 180/200), and family annual income was mainly less than 10000 yuan (48.0%, 96/200). The average personal annual medical expenditure of 5000-<10000 yuan accounted for 42.0% (84/200). The age of pneumoconiosis patients in the control group was (59.2±8.9) years old, and the working age of dust exposure was (20.2±10.5) years. The main source of income was retirement pension or salary (99.0%, 198/200), with retirement as the main employment status (66.0%, 132/200), the main personal monthly income was 2000-<4000 yuan (61.5%, 123/200), the main family annual income was 20000-<40000 yuan (44.0%, 88/200), and the average personal annual medical expenditure was mostly non-expenditure (92.0%, 184/200). There were statistically significant differences in the distribution of economic sources, employment status, personal monthly income, family annual income and average personal annual medical expenditure between the two groups (P<0.001). The main type of insurance for the observation group was rural cooperative medical care (68.5%, 137/200), and 87.0% (174/200) had no medical reimbursement and a proportion less than 50%. There were statistically significant differences in insurance type and medical reimbursement proportion between the two groups (P<0.001). The respiratory symptoms, activity ability, daily life influence and total quality of life scores of pneumoconiosis patients in the observation group were significantly higher than those in the control group, the differences were statistically significant (P<0.001) . Conclusion: Migrant workers with pneumoconiosis have low income, high medical expenditure, low medical reimbursement proportion and poor quality of life. Therefore, it is necessary to draw high attention from relevant departments and provide timely attention and assistance to improve the quality of life of migrant workers with pneumoconiosis.

ABSTRACT

Ingestion of corrosive substances can severely burn the upper digestive tract leading to bleeding or perforation, and may even be life-threatening. Less commonly, damage to the trachea and bronchi is involved. In this paper, a case of corrosive digestive tract injury and lung injury after oral administration of pipeline dredging agent (the main components are hydroxide, sodium carbonate, sodium hypochlorite, etc.) was analyzed. After active rescue treatment, the patient died of massive hemoptysis. It is suggested that serious complications may occur after ingestion of corrosive substances. Timely diagnosis and reasonable medical management are needed to improve the level of recognition and treatment of such diseases.

ABSTRACT

AIM: To study the role and mechanism of curcumol in neovascularization induced by vascular endothelial growth factor(VEGF).METHODS: Human umbilical vein endothelial cells were cultured in vitro and treated with 50ng/mL VEGF and curcumol at different concentrations. Cell proliferation was detected by CCK-8 and EdU assay, the migration ability of cells was analyzed by Transwell assay, the angiogenesis ability of endothelial cells was analyzed by tube formation assay, and the change of Akt/mTORC1 signal pathway was detected by Western blot.RESULTS: CCK-8 results showed that the OD450 value of cells in 400 and 800 μmol/L curcumol+VEGF group was significantly lower than that in VEGF group(all P<0.01). EdU results showed that the rate of cell proliferation in 400 μmol/L curcumol+VEGF group was significantly lower than that in VEGF group(P<0.001). Transwell assay and the formation assay results showed that the number of migratory cells in 400 μmol/L curcumol+VEGF group was decreased, and the number and length of tube branches were also reduced compared with VEGF group(all P<0.001). Western blot results showed that curcumol significantly inhibited the expression of p-Akt and p-S6, which were downstream targets of Akt/mTORC1 pathway in cells.CONCLUSION: Curcumol can inhibit VEGF-induced cell proliferation, migration and tube formation of vein endothelial cells, and has a strong inhibitory effect on angiogenesis, which can be further studied in the treatment of ocular fundus neovascularization.

ABSTRACT

OBJECTIVE@#To evaluate the changes of periodontal phenotype (width of keratinized gingiva, thickness and height of alveolar bone) of lower anterior teeth in patients with skeletal class Ⅲ malocclusion before and after the periodontal-orthodontic-orthognathic combined treatment.@*METHODS@#In the study, 20 patients with skeletal class Ⅲ malocclusion (6 males and 14 females) completed the periodontal-orthodontic-orthognathic combined treatment were included from March 2017 to June 2022, with 39 central incisors, 40 lateral incisors and 40 canines. The mean age was (25.40±4.27) years (20-34 years). The mean follow-up time was (3.70±1.05) years from the beginning of periodontal corticotomy regenerative surgery (PCRS) to the end of the combined treatment. Cone-beam computed tomography (CBCT) was used to measure the thickness, area and height of alveolar bone by the same researcher, taken before the PCRS (T0), 6 months after the PCRS (T1), 12 months after the PCRS (T2), before the orthognathic surgery (T3), and after the periodontal-orthodontic-orthognathic combined treatment (T4). The periodontal clinical parameters were used to evaluate changes in the soft tissue by another researcher, measured before the PCRS (T0) and after the combined treatment (T4). Changes of soft and hard tissue were evaluated by the periodontal phenotype.@*RESULTS@#The width of keratinized gingiva increased significantly (all P < 0.001) in lower anterior teeth, the central incisors, lateral incisors and canines increased by (1.82±1.57) mm, (2.03±1.48) mm and (2.05±1.27) mm, respectively. The proportion of thick periodontal biotype in the central and lateral incisors increased significantly (all P < 0.001), while the changes of periodontal biotypes in the lower canines were not obvious. The thickness of labial alveolar bone of lower anterior teeth all increased significantly after periodontal corticotomy regenerative surgery and the combined treatment (all P < 0.001). The area of labial alveolar bone of lower anterior teeth also increased significantly after the combined treatment (all P < 0.001). The whole area of labial and lingual alveolar bone of central and lateral incisors increased (P < 0.001), while the whole area of canines remained the same. All The height of the alveolar bone increased (all P < 0.001) on the labial side after the treatment.@*CONCLUSION@#The periodontal phenotypes of lower anterior teeth were significantly improved after the periodontal-orthodontic-orthognathic combined treatment in patients with skeletal Angle class Ⅲ malocclusion. The improvement was long-termly stable, and the periodontal risk was reduced.
