ABSTRACT

Major natural disasters seriously threaten human life and health. After earthquakes and other catastrophes, survivors are often trapped in the confined spaces caused by the collapse of ground and buildings, with relative separation from the outside world, restricted access, complex environment, and oncoming or ongoing unsafety, leading to the rescue extremely difficult. In order to save lives and improve the outcome more efficiently in the confined spaces after natural disasters, it is very important to standardize and reasonably apply the trauma assessment and first aid workflow. This study focuses on trauma assessment and first aid. From the aspects of trauma assessment, vital signs stabilization, hemostasis and bandaging, post-trauma anti-infection, and the transportation of patients, a trauma first aid work process suitable for a small space of a major natural disaster is formed, It is helpful to realize the immediate and efficient treatment of trauma in the confined spaces after natural catastrophes, to reduce the rate of death and disability and improve the outcome of patients.

ABSTRACT

BACKGROUND@#Butylphthalide (NBP) and edaravone (EDV) injection are common acute ischemic stroke medications in China, but there is a lack of large real-world safety studies on them. This study aimed to determine the incidence of adverse events, detect relevant safety signals, and assess the risk factors associated with these medications in real-world populations.@*METHODS@#In this study, data of acute ischemic stroke patients were extracted from the electronic medical record database of six tertiary hospitals between January 2019 and August 2021. Baseline confounders were eliminated using propensity score matching. The drugs' safety was estimated by comparing the results of 24 laboratory tests standards on liver function, kidney function, lipid level, and coagulation function. The drugs' relative risk was estimated by logistic regression. A third group with patients who did not receive NBP or EDV was constructed as a reference. Prescription sequence symmetry analysis was used to evaluate the associations between adverse events and NBP and EDV, respectively.@*RESULTS@#81,292 patients were included in this study. After propensity score matching, the NBP, EDV, and third groups with 727 patients in each group. Among the 15 test items, the incidence of adverse events was lower in the NBP group than in the EDV group, and the differences were statistically significant. The multivariate logistic regression equation revealed that NBP injection was not a promoting factor for abnormal laboratory test results, whereas EDV had statistically significant effects on aspartate transaminase, low-density lipoprotein cholesterol and total cholesterol. Prescription sequence symmetry analysis showed that NBP had a weak correlation with abnormal platelet count. EDV had a positive signal associated with abnormal results in gamma-glutamyl transferase, alanine aminotransferase, aspartate aminotransferase, prothrombin time, and platelet count.@*CONCLUSIONS@#In a large real-world population, NBP has a lower incidence of adverse events and a better safety profile than EDV or other usual medications.

ABSTRACT

Pentaxin 3 (PTX3), as a multifunctional glycoprotein, plays an important role in regulating inflammatory response, promoting tissue repair, inducing ectopic calcification and maintaining bone homeostasis. The effect of PTX3 on bone mineral density (BMD) may be affected by many factors. In PTX3 knockout mice and osteoporosis (OP) patients, the deletion of PTX3 will lead to decrease of BMD. In Korean community "Dong-gu study", it was found that plasma PTX3 was negatively correlated with BMD of femoral neck in male elderly patients. In terms of bone related cells, PTX3 plays an important role in maintaining the phenotype and function of osteoblasts (OB) in OP state;for osteoclast (OC), PTX3 in inflammatory state could stimulate nuclear factor κ receptor activator of nuclear factor-κB ligand (RANKL) production and its combination with TNF-stimulated gene 6(TSG-6) could improve activity of osteoclasts and promote bone resorption;for mesenchymal stem cells (MSCs), PTX3 could promote osteogenic differentiation of MSCs through PI3K/Akt signaling pathway. In recent years, the role of PTX3 as a new bone metabolism regulator in OP and fracture healing has been gradually concerned by scholars. In OP patients, PTX3 regulates bone mass mainly by promoting bone regeneration. In the process of fracture healing, PTX3 promotes fracture healing by coordinating bone regeneration and bone resorption to maintain bone homeostasis. In view of the above biological characteristics, PTX3 is expected to become a new target for the diagnosis and treatment of OP and other age-related bone diseases and fracture healing.

ABSTRACT

This study retrieved Croci Stigma related literature from CNKI, Wanfang, VIP, and Web of Science database, and used bibliometrics and CiteSpace 6.1.R2 software to analyze the published Croci Stigma related articles in Chinese and English from 2000 to 2022. The authors, research institutions, and keywords were visualized and analyzed, and the current status and development trend of Croci Stigma research was summarized by combining the information extraction methods. A total of 1 846 Chinese articles and 2 703 English articles were screened out and included. The results showed a generally steady increase in the number of Croci Stigma related articles. The results of the visualization analysis showed that there were more collaborations between researcher teams and major research institutions in English articles than Chinese articles. The Chinese articles was mainly published by China Pharmaceutical University, and most of the inter-institutional collaborations occurred in neighboring regions. The English articles was mainly published by Iranian institutions, and most of the cooperation occurred within the country, with less transnational cooperation. Keywords analysis showed that the research on Croci Stigma was mainly focused on chemical compositions, pharmacological effects, mechanisms, quality control, etc. It was predicted that the future research hotspots of Croci Stigma would mainly focus on pharmacological mechanism and clinical efficacy. The current research related to Croci Stigma still needs to be developed, cooperation should be strengthened, and more in-depth research should be conducted.

ABSTRACT

Arrhythmia is an external manifestation of cardiac electrophysiological disorder. It exists in healthy people and patients with various heart diseases, which is often associated with other cardiovascular diseases. The contraction and diastole of myocardium are inseparable from the movement of ions. There are many ion channels in the membrane and organelle membrane of myocardium. The dynamic balance of myocardial ions is vital in maintaining myocardial electrical homeostasis. Potassium ion channels that have a complex variety and a wide distribution are involved in the whole process of resting potential and action potential of cardiomyocytes. Potassium ion channels play a vital role in maintaining normal electrophysiological activity of myocardium and is one of the pathogenesis of arrhythmia. Traditional Chinese medicine(TCM)has unique advantages in treating arrhythmia for its complex active components and diverse targets. A large number of TCM preparations have definite effect on treating arrhythmia-related diseases, whose antiarrhythmic mechanism may be related to the effect on potassium channel. This article mainly reviewed the relevant studies on the active components in TCM acting on different potassium channels to provide references for clinical drug use and development.

ABSTRACT

The purity of 4,4′-dimethoxy-5,6,5′,6′-bis (methylenedioxy)-2′-morpholine methylenebiphenyl-2-methyl formate methanesulfonate (IMH), a new drug for fatty liver treatment, was determined through differential scanning calorimetry (DSC). Analysis of two-factor non repeatability method was performed in the investigation the effects of two factors (heating rate and sample weight) on purity determination. The DSC experimental parameters were optimized as follows: heating rate was 10 ℃·min-1, temperature range was 150-300 ℃, sample weight was 2.0-4.1 mg, and N2 flow rate was 80 mL·min-1. The linear correlation coefficient (r) of this DSC method was 0.999 8. The RSD value (n = 6) of precision was 0.03%. The standard value and uncertainty of the purity results of the multiple batches of IMH drugs were (99.74 ± 0.29)%, (99.91 ± 0.28)%, (99.90 ± 0.28)%, and (99.81 ± 0.28)% with inclusion factor (K) of 2 and confidence probability (P) of 0.95. The results were basically consistent with the results of the mass balance method. The DSC mehod is a simple, rapid and accurate method, and provides a new reference method for determining the purity of IMH drugs, improves the accuracy and reliability of purity determination.

ABSTRACT

Interpretation and consideration of “Substitution of in vivo method(s) by in vitro method(s) for the quality control of vaccines” in General Texts of European Pharmacopoeia@#Potency is a critical quality attribute for controlling relevant biological properties and batch consistency of vaccines.The methods can be divided into in vivo and in vitro methods according to whether animals are used.The in vivo methods are large consuming of animals and time,as well as have large variant detection results.In contrast,the in vitro alternative methods have been the hotspot of research due to their simple operations,in line with 3Rs principles,and more stable results.However,owing to the complexity of experimental design and the lack of corresponding guidance,the research progress of alternative methods is slow.Recently,“Substitution of in vivo method(s) by in vitro method(s) for the quality control of vaccines” was adopted in the European Pharmacopoeia(10th Edition),which clarifies the critical points of consideration for substitution.This paper interprets the chapter and puts forward some thoughts on that in China,which is expected to speed up the alternative methods research and improve the ability of vaccine quality control and supervision in China.

ABSTRACT

Objective:To analyze the biological characteristics, phylogenic features and clinical significance of SQ219 and SQ220 isolated from clinical sputum and midstream urine specimens.Methods:The culture and biochemical characteristics of the two strains were observed. VITEK2 System, drug sensitivity testing and MALDI-TOF mass spectrometry were used for bacterial identification. Phylogenetic analysis based on 16S rRNA and core genome was performed. The average nucleotide identity (ANI) based on whole genome sequences was calculated.Results:SQ219 and SQ220 were Gram-stain-negative, aerobic, catalase- and oxidase-positive, and non-motile bacteria. Their optimum growth was observed in NaCl-free medium at 30℃ and pH7. Flexirubin-type pigments were produced by SQ220 on Colombia blood agar, but not by SQ219. Both SQ219 and SQ220 were resistant to aztreonam, amikacin, tobramycin and colistin, which was consistent with the drug resistance phenotype of genus Chryseobacterium. The genome sequences of SQ219 and SQ220 were 5.08 Mb and 4.80 Mb in length, and the G+ C contents were 36.72% and 36.36%, respectively. Both strains carried β-lactam resistance gene ( blaCGA). 16S rRNA phylogenetic analysis showed that SQ219 and SQ220 were closely related to Chryseobacterium gambrini DSM18014 T with the similarities of 98.93% and 98.36%, respectively. Core genome phylogenetic analysis revealed that SQ219 and SQ220 were highly homologous to Chryseobacterium gambrini DSM18014 T. However, the ANI values between the two strains and Chryseobacterium gambrini DSM18014 T were 92.49% and 93.27%, respectively, below the threshold for prokaryotic species identification. Conclusions:Based on the phenotypic and phylogenetic data, SQ219 and SQ220 represent a novel species of the genus Chryseobacterium. This study would help promote the understanding of the evolution of Chrysobacterium and provide reference for the identification of new species of Chrysobacterium.

ABSTRACT

Objective:To explore any effect of the single- and dual-task treadmill training on the functioning of children with bilateral spastic cerebral palsy.Methods:Fifty children with bilateral spastic cerebral palsy were randomly divided into a single-task treadmill training group (the control group, n=25) and a dual-task treadmill training group (the observation group, n=25). All of the children also received routine rehabilitation training, and the control and observation groups also conducted single- and dual-task treadmill training in addition to the routine rehabilitation training, respectively. Before and after 2 months of treatment, each child′s gross motor functioning was quantified using sections D (standing) and E (walking, running and jumping) of the Gross Motor Function Measurement-88 (GMFM-88) instrument. Balance was quantified using the Pediatric Balance Scale (PBS) and walking mobility was quantified using a 1 minute walking test (1MWT). Modified and dual task Timed Up and Go (mTUG) tests and dual-task effects (DTE) tests were also administered. Results:There were no significant differences in average test scores between the two groups before the treatment. After the treatment significant improvement was observed in both groups. There was no significant difference between the two groups in terms of average GMFM-88, PBS and 1MWT scores, but significantly greater improvement was observed in the average dual-task mTUG and DTE results of the observation group.Conclusion:Both single- and dual-task treadmill training are effective supplements to routine rehabilitation training for children with bilateral spastic cerebral palsy. Dual-task treadmill training is more effective than the single-task version.

ABSTRACT

Objective:To explore the value of conventional ultrasonography combined with cervical compression in the diagnosis of orbital venous malformation (OVM).Methods:A total of 43 patients with suspected OVM were admitted in sequentially from January 2019 to July 2022 in the Third Medical Center of PLA General Hospital. All patients were examined by ultrasonography combined with cervical compression and demonstrated by operation or digital subtraction angiography (DSA). The conventional ultrasound features of OVM were summarized, and the value of conventional ultrasonography combined with cervical compression in the diagnosis of OVM was discussed.Results:The features of the conventional ultrasound combined with cervical compression for diagnosis of OVM were as follows: the interior of lesion was mainly tubular structure, and the compression test was positive. After cervical compression, the lesion enlarged and the inner diameter of the internal tubular structure widened. Doppler flow imaging showed that the interior of lesion was mainly venous blood flow. Compared with the results of postoperative pathology or DSA, the sensitivity, specificity, accuracy and positive predictive value of ultrasonography combined with cervical compression were 0.952, 1.000, 95.3% and 100%, respectively. The results of Fisher exact diagnosis showed that there was no significant difference between ultrasonography and operation or DSA of OVM( P>0.05). Conclusions:Conventional ultrasound combined with cervical compression can be used as an effective method for the diagnosis of OVM.

ABSTRACT

Objective:To investigate the influences of Dixon anus preserving surgery on the curative effect, anorectal function and stress response of patients with low rectal cancer.Methods:A total of 150 patients with low rectal cancer admitted to Zhangjiakou Fifth Hospital from May 2016 to March 2019 were retrospective analysis as the study subjects. According to the different surgical methods, the patients were divided into the study group (75 cases) and the control group (75 cases). The patients in the study group received Dixon operation, and the patients in the control group received Miles operation. The general condition of operation, postoperative urination function, stress response [C reactive protein (CRP), interleukin-6 (IL-6), cortisol (Cor) and adrenocorticotropic hormone (ACTH)], anorectal function [anal resting pressure (ARP), maximal squeeze pressure (MSP), anal longest contraction time (ALCT)], quality of life (PAC-QOL score), postoperative complications, local recurrence rate, distant metastasis rate, 3-year tumor free survival rate and 3-year overall survival rate were compared between the two groups.Results:The operation time, intraoperative blood loss and postoperative drainage volume in the study group were lower than those in the control group: (172.28 ± 23.45) min vs. (189.57 ± 23.68) min, (177.39 ± 21.23) ml vs. (191.35 ± 22.67) ml, (342.36 ± 52.89) ml vs. (489.42 ± 63.33) ml, there were statistical differences ( P<0.05). The levels of CRP, IL-6, Cor and ACTH in the study group were lower than those in the control group: (22.35 ± 4.75) mg/L vs. (35.65 ± 5.28) mg/L, (58.74 ± 15.11) μg/L vs. (79.63 ± 20.23) μg/L, (145.36 ± 27.48) ng/L vs. (156.48 ± 32.55) ng/L, (44.58 ± 5.27) ng/L vs. (49.62 ± 5.68) ng/L, there were statistical differences ( P<0.05). The urination function and anorectal function of the patients in the study group were obviously better than those in the control group 6 months after operation, and the PAC-QOL score was obviously lower than that in the control group: (22.53 ± 2.86) scores vs. (27.54 ± 3.21) scores ( P<0.05); there was no obvious difference between the study group and the control group in the incidence of postoperative complications, local recurrence rate, distant metastasis rate, 3-year tumor free survival rate and 3-year total survival rate ( P>0.05). Conclusions:Dixon operation is effective in the treatment of low rectal cancer. It can preserve the anorectal function of patients to the greatest extent, protect urination function, reduce stress reaction of patients, and it is more conducive to rapid rehabilitation of patients.

Objective:To investigate the clinical efficacy of da Vinci Xi surgical system assisted programmed six-hole method anterior resection of rectal cancer.Methods:The retrospec-tive cohort study was conducted. The clinicopathological data of 102 patients with middle and low rectal cancer who were admitted to the Affiliated Hospital of Xuzhou Medical University from August 2020 to June 2021 were collected. There were 62 males and 40 females, aged (53±12)years. Of the 102 patients, 51 cases undergoing da Vinci Xi surgical system assisted programmed six-hole method anterior resection of rectal cancer were divided into the robotic group and 51 cases undergoing laparoscopic anterior resection of rectal cancer were divided into the laparoscopic group. Observa-tion indicators: (1) treatment; (2) postoperative pathological examination; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Repeated measurement data were analyzed using the repeated ANOVA. Results:(1) Treatment. All patients of the two groups under-went radical resection of rectal cancer successfully, and none of patient with intraoperative blood transfusion, conversion to open surgery, and death within 30 days after surgery.

(2) Postoperative patho-logical examination. The tumor diameter, length of specimen resected, distance of upper resection margin to tumor, distance of lower resection margin to tumor, cases with mesorectal specimens as integrity and mostly integrity, cases with tumor differentiation as high differentiation, moderate differentiation, low differentiation, cases with postoperative TNM staging as stage Ⅰ, stage Ⅱ, stage Ⅲ were (3.8±1.1)cm, (18.7±3.2)cm, (11.8±3.6)cm, (2.7±0.8)cm, 48, 3, 4, 41, 6, 6, 17, 28 in patients of the robotic group, versus (3.7±1.0)cm, (18.3±2.8)cm, (10.2±2.7)cm, (2.5±0.6)cm, 46, 5, 6, 39, 6, 5,20, 26 in patients of the laparoscopic group, showing no significant difference in the above indicators between the two groups ( t=1.72, 1.29, 1.64, 1.11, χ2=0.14, Z=-0.42, -0.26, P>0.05). Cases with positive circumferential margin and cases with destruction of mesentery was 0 and 0 in patients of the robotic group, versus 1 and 1 in patients of the laparoscopic group, showing no significant difference in the above indicators between the two groups ( P>0.05). (3) Follow-up. All patients in the two groups were followed up for 12 months after surgery and none of patient had postoperative local recurrence and distant metastasis of tumors. The anal incontinence score, low anterior resection syndrome score, international prostate symptom score, night urination score, international index of erectile score, female sexual function index score in patients of the robotic group were 0, 12.25±1.08, 4.43±0.33, 0.49±0.09, 24.07±2.75, 65.84±1.79 before surgery and 1.34±0.11, 18.11±3.54, 4.03±0.26, 1.08±0.28, 22.63±2.03, 38.57±6.13 at postoperative 12 months, respectively. The above indicators in patients of the laparoscopic group were 0, 12.60±1.11, 4.56±0.36, 0.46±0.07, 23.11±2.77, 66.31±1.73 before surgery and 1.99±1.33,20.85±6.19, 6.43±1.78, 2.27±0.23, 21.00±2.73, 27.62±8.20 at postoperative 12 months, respectively. There were significant differences in the above indicators between the two groups ( P<0.05). Conclusions:The oncological effects of da Vinci Xi surgical system assisted programmed six-hole method anterior resection of rectal cancer and lapa-roscopic anterior resection of rectal cancer are comparable. However, robotic surgery is superior to laparoscopic surgery in terms of intraoperative bleeding, lymph node dissection, gastrointestinal function recovery, and pelvic autonomic nerve protection.

ABSTRACT

Objective:To formulate a ladder type early activity program in order to provide a theoretical and practical basis for improving the current activity status of tumor patients with pulmonary embolism.Methods:This research was conducted experimentally. A total of 92 tumor patients diagnosed as pulmonary embolism from January 1, 2021 to March 31, 2022 in Sichuan Cancer Hospital were divided into control group and experimental group with 46 cases each by random number table method. In the control group, a routine activity program was carried out, and the patients were confined to bed for 7 days. The experimental group obtained the best evidence of early pulmonary embolism activity plan through evidence-based nursing, formed a nurse-led ladder type early pulmonary embolism activity team, and finally constructed and implemented the ladder type early activity plan. The mortality rate, new thrombosis in ICU for 3 days and 7 days, length of stay in ICU and patients′ comfort were compared between the two groups.Results:The mortality rates within 30 days after the diagnosis of pulmonary embolism were 4.35% (2/46) and 2.17% (1/46) respectively in the control group and the experimental group, with no significant difference between the two groups ( χ2=0.35, P>0.05). The rates of new thrombosis were 15.22% (7/46) and 26.09% (12/46) in the control group, and 4.35% (2/46) and 4.35% (2/46) in the experimental group, respectively at 3 and 7 days after ICU admission, with a significant difference between the two groups at 7 days after ICU admission ( χ2=8.43, P<0.05). The length of stay in ICU and the score of General Comfort Questionnaire (GCQ) were (15.74 ± 11.11) days and (64.30 ± 15.54) points in the experimental group, respectively, while those in the control group were (11.07 ± 5.63)days and (73.84 ± 11.73) points, respectively. The difference between the two groups was statistically significant ( t=-2.55, -3.32, both P<0.05). Conclusions:The evidence-based ladder type early activity program for patients with pulmonary embolism caused by tumor will not increase the mortality of patients, but can ensure the safety of patients, reduce the incidence of new thrombosis and the length of ICU stay, improve the comfort of patients during the treatment of pulmonary embolism. It is worthy of clinical application.

ABSTRACT

Objective:To investigate the indication, effectiveness, tolerance, and safety of levosimendan in patients with acute heart failure (AHF) in 20 hospitals in Beijing, China.Methods:This prospective, observational, and multicenter study consecutively enrolled AHF patients who were treated with levosimendan at 20 hospitals in Beijing from April 2020 to March 2022. Baseline demographics, laboratory parameters, clinical presentation, concomitant diseases and medications were collected. After initiation of levosimendan, levosimendan administration, laboratory parameter pre- and post-administration, symptoms improvement, and adverse events were also collected.Results:Totally 800 AHF patients were included, 67% of whom were male, aged (65 ±17) years, 50% of whom had ischemic heart disease, and the left ventricular ejection fraction (LVEF) was (36±11)%. The dose of levosimendan was (11.84 ±2.11) mg and the mean infusion time was (1 450±307) min. Dyspnea was improved in 83.4% of AHF patients at 24 h after treatment. The level of B-type natriuretic peptide (BNP) significantly decreased from 689 (406-1509) pg/mL to 410 (156-697) pg/mL in all patients at 24-72 h after treatment ( P<0.001), and the level of N-terminal pro-brain natriuretic peptide (NT-pro BNP) decreased from 6910 (3 715-13 914) pg/mL to 2 851 (1 288-6 191) pg/mL ( P<0.001). Meanwhile, LVEF level also improved significantly [(40±11)% vs. (36±11)%, P<0.001]. During levosimendan administration, adverse events occurred in 74 (9.3%) patients, including hypotension (5.9%), arrhythmia (1.9%), and other symptoms (1.1%). Among them, 7 patients ( 2 patients with hypotension and 5 patients with ventricular tachycardia) interrupted levosimendan administration. Conclusions:The use of levosimendan is safe, and can improve symptoms reduce BNP or NT-pro BNP levels and increase LVEF level in AHF patients.

ABSTRACT

Objective Aiming at the medial prosthetic loosening failure and lateral cartilage degeneration after unicompartmental knee arthroplasty ( UKA), the effects of prosthetic installation errors of joint line in UKA on knee contact mechanics and kinematics during different physiologic activities were studied using musculoskeletal multi-body dynamic method. Methods Taking the medial natural joint line as 0 mm error, six installation errors ofjoint line including ±2 mm, ±4 mm and ±6 mm were considered respectively, and seven musculoskeletal multi body dynamic models of medial UKA were established, to comparatively study the variations in knee contact mechanics and kinematics during walking and squatting. Results At 70% of walking gait cycle, compared with 0 mm error, the medial prosthetic contact force was increased by 127. 3% and the contact force of the lateral cartilage was decreased by 12. 0% under 2 mm elevation in joint line, the medial prosthetic contact force was close to 0 N, but the lateral cartilage contact forces were increased by 10. 1% under 4 mm reduction in joint line. The tibiofemoral total contact forces were increased by 19. 7% and decreased by 14. 2% under 2 mm elevation and 2 mm reduction in joint line, respectively. At the 100°knee flexion during squatting, compared with 0 mm error, the medial prosthetic contact force and the tibiofemoral total contact force increased by 31. 6% and 11. 1% under 2 mm elevation in joint line, and decreased by 24. 5% and 8. 5% under 2 mm reduction in joint line, respectively. The change in the lateral cartilage contact force was not marked. Moreover, at 70% of walking gait cycle, the varus angle decreased, the internal rotation and the anterior translation increased along with the elevation of joint line in UKA, while it was just the opposite along with the reduction of joint line in UKA. The trends of the varus valgus movement and anterior-posterior translation during squatting were consistent with those during swing phase of walking, but the trend of the internal-external rotation was opposite. Conclusions In order to reduce the risk of medial prosthetic loosening failure and lateral cartilage degeneration, it is recommended that the installation error of joint line in UKA should be controlled in the range of -2 mm to +2 mm. This study provides theoretical basis for UKA clinical failure caused by changes in joint line

ABSTRACT

To explore the digital manufacturing process of distal extension removable partial denture. From November 2021 to December 2022, 12 patients (7 males and 5 females) with free-ending situation were selected from the Department of Prosthodontics, School of Stomatology, The Fourth Military Medical University. Three-dimensional model of the relationship between alveolar ridge and jaw position was obtained by intraoral scanning technique. After routine design, manufacturing and try-in of metal framework for removable partial denture, the metal framework was located in the mouth and scanned again to obtain the composite model of dentition, alveolar ridge and metal framework. The free-end modified model is obtained by merging the digital model of free-end alveolar ridge with the virtual model with the metal framework. The three-dimensional model of artificial dentition, and base plate was designed on the free-end modified model, and the resin model were made by digital milling technology. The removable partial denture was made by accurately positioning the artificial dentition and base plate, bonding metal framework with injection resin, grinding and polishing the artificial dentition and resin base. Compared with the design data after clinical trial, the results showed that there was an error of 0.4-1.0 mm and an error of 0.03-0.10 mm in the connection between the resin base of artificial dentition and the connecting rod of the in-place bolt and the connection between artificial dentition and resin base. After denturen delivery, only 2 patients needed grinding adjustment in follow-up visit due to tenderness, and the rest patients did not find any discomfort. The digital fabrication process of removable partial denture used in this study can basically solve the problems of digital fabrication of free-end modified model and assembly of artificial dentition with resin base and metal framework.

ABSTRACT

Objective To evaluate the role and potential mechanism of interleukin (IL)-18/IL-18 binding protein (BP) in mediating the killing effect of natural killer (NK)-92MI cells upon endothelial cells from α-1, 3- galactosyltransferase gene-knockout (GTKO) porcine models. Methods NK-92MI cells were divided into the NK, NK+IL-18, NK+GTKO, IL-18+NK+GTKO and IL-18+IL-18BP+NK+GTKO groups. The messenger ribonucleic acid (mRNA) levels of inflammation-related genes in NK-92MI cells were detected by quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR). The killing effect of NK-92MI cells on endothelial cells from GTKO porcine models was evaluated by lactate dehydrogenase (LDH) assay. The apoptosis of endothelial cells from GTKO porcine models was assessed by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay. The expression levels of proteins with killing effect and apoptosis-related proteins were determined by Western blot. Results Compared with the NK, NK+IL-18 and NK+GTKO groups, the expression levels of interferon (IFN)-γ, tumor necrosis factor (TNF)-α, IL-8, IL-3, IL-6 and granulocyte-macrophage colony stimulating factor (GM-CSF) mRNA were up-regulated in NK-92MI cells in the IL-18+NK+GTKO group, and the differences were statistically significant (all P < 0.05). Compared with the IL-18+NK+GTKO group, the expression levels of IFN-γ, TNF-α, IL-8, IL-3, IL-6 and GM-CSF mRNA were down-regulated in NK-92MI cells in the IL-18+IL-18BP+NK+GTKO group, and the differences were statistically significant (all P < 0.05). Compared with the NK+GTKO group, the expression levels of perforin, granzyme B and IFN-γ proteins in NK-92MI cells were up-regulated, the killing rate of NK-92MI cells against endothelial cells from GTKO porcine models was enhanced, the apoptosis rate of endothelial cells from GTKO porcine models was increased, and the ratios of B cell lymphoma-2 (Bcl-2)-associated X protein (Bax)/Bcl-2 and cleaved Caspase-3/Caspase-3 in endothelial cells from GTKO porcine models were elevated in the IL-18+NK+GTKO group, and the differences were statistically significant (all P < 0.05). Compared with the IL-18+NK+GTKO group, the expression levels of perforin, granzyme B and IFN-γ proteins were down-regulated, the killing rate of NK-92MI cells against endothelial cells from GTKO porcine models was decreased, the apoptosis rate of endothelial cells from GTKO porcine models was decreased, and the ratios of Bax/Bcl-2 and cleaved Caspase-3/Caspase-3 in endothelial cells from GTKO porcine models were declined in the IL-18+IL-18BP+NK+GTKO group, and the differences were statistically significant (all P < 0.05). Conclusions IL-18BP may block the expression of inflammation-related genes in NK-92MI cells induced by IL-18 and the killing effect of NK-92MI cells on endothelial cells from GTKO porcine models.

ABSTRACT

OBJECTIVE@#To screen the risk factors for death in patients with nasopharyngeal carcinoma (NPC) using artificial intelligence (AI) technology and establish a risk prediction model.@*METHODS@#The clinical data of NPC patients obtained from SEER database (1973-2015). The patients were randomly divided into model building and verification group at a 7∶3 ratio. Based on the data in the model building group, R software was used to identify the risk factors for death in NPC patients using 4 AI algorithms, namely eXtreme Gradient Boosting (XGBoost), Decision Tree (DT), Least absolute shrinkage and selection operator (LASSO) and random forest (RF), and a risk prediction model was constructed based on the risk factor identified. The C-Index, decision curve analysis (DCA), receiver operating characteristic (ROC) curve and calibration curve (CC) were used for internal validation of the model; the data in the validation group and clinical data of 96 NPC patients (collected from First Affiliated Hospital of Bengbu Medical College) were used for internal and external validation of the model.@*RESULTS@#The clinical data of a total of 2116 NPC patients were included (1484 in model building group and 632 in verification group). Risk factor screening showed that age, race, gender, stage M, stage T, and stage N were all risk factors of death in NPC patients. The risk prediction model for NPC-related death constructed based on these factors had a C-index of 0.76 for internal evaluation, an AUC of 0.74 and a net benefit rate of DCA of 9%-93%. The C-index of the model in internal verification was 0.740 with an AUC of 0.749 and a net benefit rate of DCA of 3%-89%, suggesting a high consistency of the two calibration curves. In external verification, the C-index of this model was 0.943 with a net benefit rate of DCA of 3%-97% and an AUC of 0.851, and the predicted value was consistent with the actual value.@*CONCLUSIONS@#Gender, age, race and TNM stage are risk factors of death of NPC patients, and the risk prediction model based on these factors can accurately predict the risks of death in NPC patients.
