ABSTRACT

Objective:To assess the effectiveness of a model created using clinical features and preoperative chest CT imaging features in predicting the chronic obstructive pulmonary disease (COPD) among patients diagnosed with lung cancer.Methods:A retrospective analysis was conducted on clinical (age, gender, smoking history, smoking index, etc.) and imaging (lesion size, location, density, lobulation sign, etc.) data from 444 lung cancer patients confirmed by pathology at the Second Affiliated Hospital of Naval Medical University between June 2014 and March 2021. These patients were randomly divided into a training set (310 patients) and an internal test set (134 patients) using a 7∶3 ratio through the random function in Python. Based on the results of pulmonary function tests, the patients were further categorized into two groups: lung cancer combined with COPD and lung cancer non-COPD. Initially, univariate analysis was performed to identify statistically significant differences in clinical characteristics between the two groups. The variables showing significance were then included in the logistic regression analysis to determine the independent factors predicting lung cancer combined with COPD, thereby constructing the clinical model. The image features underwent a filtering process using the minimum absolute value convergence and selection operator. The reliability of these features was assessed through leave-P groups-out cross-validation repeated five times. Subsequently, a radiological model was developed. Finally, a combined model was established by combining the radiological signature with the clinical features. Receiver operating characteristic (ROC) curves and decision curve analysis (DCA) curves were plotted to evaluate the predictive capability and clinical applicability of the model. The area under the curve (AUC) for each model in predicting lung cancer combined with COPD was compared using the DeLong test.Results:In the training set, there were 182 cases in the lung cancer combined with COPD group and 128 cases in the lung cancer non-COPD group. The combined model demonstrated an AUC of 0.89 for predicting lung cancer combined with COPD, while the clinical model achieved an AUC of 0.82 and the radiological model had an AUC of 0.85. In the test set, there were 78 cases in the lung cancer combined with COPD group and 56 cases in the lung cancer non-COPD group. The combined model yielded an AUC of 0.85 for predicting lung cancer combined with COPD, compared to 0.77 for the clinical model and 0.83 for the radiological model. The difference in AUC between the radiological model and the clinical model was not statistically significant ( Z=1.40, P=0.163). However, there were statistically significant differences in the AUC values between the combined model and the clinical model ( Z=-4.01, P=0.010), as well as between the combined model and the radiological model ( Z=-2.57, P<0.001). DCA showed the maximum net benifit of the combined model. Conclusion:The developed synthetic diagnostic combined model, incorporating both radiological signature and clinical features, demonstrates the ability to predict COPD in patients with lung cancer.

ABSTRACT

Objective: T lymphocyte exhaustion is an important component of immune dysfunction. Therefore, exploring peripheral blood-exhausted T lymphocyte features in patients with hepatitis B virus-related acute-on-chronic liver failure may provide potential therapeutic target molecules for ACLF immune dysfunction. Methods: Six cases with HBV-ACLF and three healthy controls were selected for T-cell heterogeneity detection using the single-cell RNA sequencing method. In addition, exhausted T lymphocyte subpopulations were screened to analyze their gene expression features, and their developmental trajectories quasi-timing. An independent sample t-test was used to compare the samples between the two groups. Results: Peripheral blood T lymphocytes in HBV-ACLF patients had different differentiation trajectories with different features distinct into eight subpopulations. Among them, the CD4(+)TIGIT(+) subsets (P = 0.007) and CD8(+)LAG3(+) (P = 0.010) subsets with highly exhausted genes were significantly higher than those in healthy controls. Quasi-time analysis showed that CD4(+)TIGIT(+) and CD8(+)LAG3(+) subsets appeared in the late stage of T lymphocyte differentiation, suggesting the transition of T lymphocyte from naïve-effector-exhausted during ACLF pathogenesis. Conclusion: There is heterogeneity in peripheral blood T lymphocyte differentiation in patients with HBV-ACLF, and the number of exhausted T cells featured by CD4(+)TIGIT(+)T cell and CD8(+)LAG3(+) T cell subsets increases significantly, suggesting that T lymphocyte immune exhaustion is involved in the immune dysfunction of HBV-ACLF, thereby identifying potential effective target molecules for improving ACLF patients' immune function.

ABSTRACT

Objective To compare the prediction effect of combined model and single model in HFRS incidence fitting and prediction, and to provide a reference for optimizing HFRS prediction model. Methods The province with the highest incidence in China (Heilongjiang Province) in recent years was selected as the research site. The monthly incidence data of HFRS in Heilongjiang Province from 2004 to 2017 were collected. The data from 2004 to 2016 was used as training data, and the data from January to December 2017 was used as test data. The training data was used to train SARIMA , ETS and NNAR models, respectively. The reciprocal variance method and particle swarm optimization algorithm (PSO) were used to calculate the model coefficients of SARIMA, ETS and NNAR, respectively, to construct combined model A and combined model B. The established models were used to predict the incidence of HFRS from January to December 2017. The fitted and predicted values of the five models were compared with the training data and test data, respectively. Mean Absolute Percentage Error (MAPE), Mean Absolute Error (MAE), Root Mean Standard Deviation (RMSE), and Mean Error Rate (MER) were used to evaluate the model fitting and prediction effects. Results The optimal SARIMA model was SARIMA(1,0,2)(2,1,1)12. The optimal ETS model was ETS(M, N, M), and the smoothing parameter =0.738,=1*10. The optimal NNAR model was NNAR(13,1,7)12. The residuals of the three single models were white noise (P>0.05). The expression of combined model A was ŷ=0.134*ySARIMA+0.162*yETS+0.704*yNNAR; the expression of combined model B was ŷ=0.246*ySARIMA+0.435*yETS+0.319*yNNAR. The MAPE, MAE, RMSE, and MER fitted by SARIMA, ETS, NNAR, combined model A and combined model B were 24.10%, 0.11, 0.17, 23.29%; 17.14%, 0.08, 0.14, 17.96%; 6.33%, 0.02, 0.03, 4.25%; 9.03%, 0.03, 0.05, 7.51%; 13.16%, 0.06, 0.09, 12.33%, respectively. The MAPE, MAE, RMSE, and MER predicted by the five models were 18.70%, 0.05, 0.06, 19.62%; 23.83%, 0.06, 0.07, 24.49%; 28.30%, 0.07, 0.10, 29.21%; 21.69%, 0.06, 0.08, 22.63%; 17.39%, 0.05, 0.07, 18.76%, respectively. Conclusion The fitting and prediction effects of the combined models are better than the single models. The combined model based on PSO to calculate the weight of the single model is the optimal model.

ABSTRACT

Antibiotics are playing an increasingly important role in clinical antibacterial applications. However, their abuse has also brought toxic and side effects, drug-resistant pathogens, decreased immunity and other problems. New antibacterial schemes in clinic are urgently needed. In recent years, nano-metals and their oxides have attracted wide attention due to their broad-spectrum antibacterial activity. Nano-silver, nano-copper, nano-zinc and their oxides are gradually applied in biomedical field. In this study, the classification and basic properties of nano-metallic materials such as conductivity, superplasticity, catalysis, and antibacterial activities were firstly introduced. Secondly, the common preparation techniques, including physical, chemical and biological methods, were summarized. Subsequently, four main antibacterial mechanisms, such as cell membrane, oxidative stress, DNA destruction and cell respiration reduction, were summarized. Finally, the effect of size, shape, concentration and surface chemical characteristics of nano-metals and their oxides on antibacterial effectiveness and the research status of biological safety such as cytotoxicity, genotoxicity and reproductive toxicity were reviewed. At present, although nano-metals and their oxides have been applied in medical antibacterial, cancer treatment and other clinical fields, some issues such as the development of green preparation technology, the understanding of antibacterial mechanism, the improvement of biosafety, and the expansion of application fields, require further exploration.

ABSTRACT

Objective:To analyze the clinical characteristics and risk factors of impaired liver and renal function in hospitalized patients with gout.Methods:A total of 494 hospitalized patients with confirmed gout were selected and divided into four groups according to liver and renal function, control(Con), impaired liver function (ILF), impaired renal function (IRF), and both function impaired (ILRF) group. Multivariate logistic regression was used to analyze the risk factors related with impaired liver and renal function.Results:Compared to Con group, ILF group were younger with shorter gout duration, higher body mass index, waist circumference, homeostasis model assessment for insulin resistance (HOMA-IR), serum uric acid, low density lipoprotein-cholesterol (LDL-C), total cholesterol, triglycerides, C reactive protein, higher prevalence of dyslipidemia, obesity, fatty liver, and monosodium urate crystal (MSU) deposition (all P<0.05). IRF group were older and with higher serum uric acid, serum creatinine, C reactive protein, and hypertension, MSU deposition prevalence, with lower prevalence of fatty liver (all P<0.05). Compared to ILF group, IRF group were older, with longer gout duration, lower level of body mass index, waist circumference, HOMA-IR, LDL-C, total cholesterol, triglycerides, lower prevalence of obesity, fatty liver, and higher prevalence of hypertension and type 2 diabetes (all P<0.05). The univariate logistic regression analysis showed that age( OR=0.941, 95% CI 0.906-0.977, P<0.001), serum uric acid ( OR=1.002, 95% CI 1.000-1.005, P=0.043), HOMA-IR ( OR=1.147, 95% CI 1.024-1.285, P=0.018), and MSU deposition ( OR=1.959, 95% CI 1.154-3.326, P=0.013) were the independent risk factors of impaired liver function, while the independent risk factors of impaired renal function were age ( OR=1.104, 95% CI 1.048-1.162, P<0.001), serum uric acid ( OR=1.007, 95% CI 1.004-1.010, P<0.001), and MSU deposition ( OR=2.393, 95% CI 1.191-4.805, P=0.014). Conclusions:Serum uric acid and MSU deposition are the common independent risk factors for impaired liver and renal function in patients with gout. Younger patients with insulin resistance are susceptible to impaired liver function, older patients with hypertension and diabetes are susceptible to impaired renal function.

ABSTRACT

Objective:To analyze the influencing factors of gout patients and explore whether there is an interaction between serum uric acid and diastolic blood pressure affecting the onset of tophi.Methods:A total of 4 798 gout patients were retrospective selected in the outpatient Department of the Gout Clinical Medical Center of the Affiliated Hospital of Qingdao University from September 2016 to May 2020. It was divided into tophi group and non-tophi group to compare the differences in indicators. A logistic regression model was used to analyze the influencing factors of tophi, and an interaction model was constructed to analyze the interactions.Results:Multivariate logistic regression analysis showed significant associations between age, diastolic blood pressure, alcohol consumption history, gout family history, blood uric acid, urea nitrogen, and creatinine clearance and tophi formation. The results of blood uric acid-related interaction analysis showed a significant interaction between blood uric acid and diastolic blood pressure( Pinteraction=0.014), and the risk of developing tophi in low diastolic blood pressure and high diastolic blood pressure group increased by 34.4%( OR=1.344, 95% CI 1.105-1.635, P=0.003) and 95.4%( OR=1.954, 95% CI 1.558-2.450, P<0.001) in the high blood uric acid group compared with the low blood uric acid group. The results of diastolic blood pressure and blood uric acid subgroup analysis showed that there was no statistical difference in the risk of developing tophi in people with low uric acid levels( P=0.238), but in people with high uric acid levels, the risk of developing tophi was 67%( OR=1.670, 95% CI 1.379-2.022, P<0.001) higher than that in the low uric acid group. Conclusion:Age, diastolic blood pressure, combined alcohol consumption history and gout family history, blood uric acid, renal function are related to the occurrence of tophi. High uric acid and high diastolic blood pressure have interaction on the occurrence of tophi. Attention and proactive intervention shall be applied to this group of patients.

ABSTRACT

OBJECTIVE@#To evaluate the sensitivity and specificity of Pollard' s classification criteria(2010) for the diagnosis of rheumatoid arthritis (RA) patients withfibromyalgia (FM) in Chinese patients, and to assess the clinical features and psychological status of RA-FM patients in a real-world observational setting.@*METHODS@#Two hundred and two patients with rheumatoid arthritis were enrolled from the outpatients in Rheumatology and Immunology Department in Peking University People' s Hospital. All the patients were evaluated whether incorporating fibromyalgia translation occured using the 1990 American College of Rheumatolgy (ACR)-FM classification criteria. Forty two RA patients were concomitant with FM, while the other one hundred and sixty RA patients without FM were set as the control group.@*RESULTS@#There was no significant difference in general demography between the two groups (P>0.05). In this study, the Pollard' s classification criteria (2010) for RA-FM in Chinese patients had a high sensitivity of 95.2% and relatively low specificity of 52.6%. Compared with those patients without FM, RA patients with FM (RA-FM patients) had higher Disease Activity Scale in 28 joints (DAS-28) score (5.95 vs. 4.38, P=0.011) and much more 28-tender joint counts (TJC) (16.5 vs.4.5, P < 0.001).RA-FM patients had worse Health Assessment Questionnaire (HAQ) score (1.24 vs. 0.66, P < 0.001) and lower SF-36 (28.63 vs. 58.22, P < 0.001). Fatigue was more common in RA-FM patients (88. 1% vs. 50.6%, P < 0.001) and the degree of fatigue was significantly increased in RA-FM patients (fatigue VAS 5.55 vs. 3.55, P < 0.001). RA-FM patients also had higher anxiety (10 vs.4, P < 0.001) and depression scores (12 vs.6, P < 0.001). erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), morning stiffness time and 28-swollen joint counts (SJC) showed no difference between these two groups.@*CONCLUSION@#The Pollard' s classification criteria (2010) for RA-FM are feasible in Chinese rheumatoid arthritis patients. The Pollard' s classification criteria is highly sensitive in clinical application, while the relativelylow specificity indicates that various factors need to be considered in combination. RA patients with FM result in higher disease activity, worse function aland psychological status. RA patients with FM also have poorer quality of life. DAS-28 scores may be overestimated in RA patients with FM. In a RA patient thatdoes not reach remission, the possibility of fibromyalgia should be con-sidered.

ABSTRACT

The present study explored the underlying mechanism of Astragali Radix-Curcumae Rhizoma-Paridis Rhizoma(AR-CR-PR) in the treatment of colorectal cancer(CRC) by network pharmacology and molecular docking and animal tests and verified the core targets based on the orthotopic transplantation model in nude mice. The active components of AR-CR-PR were retrieved from databases such as TCMSP. The targets of drugs and the disease were obtained from PubChem, SwissTargetPrediction, TTD, and DrugBank, and the intersection targets were imported into STRING for the analysis of the protein-protein interaction(PPI). Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) analyses were performed through DAVID. AutoDock Vina was used to perform molecular docking and binding ability prediction between the active components and the core targets. The effects of AR-CR-PR on tumor growth, metastasis, and phosphorylation of core target proteins in tumor tissues based on the orthotopic transplantation model in nude mice. As revealed by network pharmacology, AR-CR-PR contained nine core components, such as quercetin, curcumin, and β-ecdysone, and the key targets included protein kinase B(AKT1), mitogen-activated protein kinase 3(MAPK3), MAPK1, and epithelial growth factor receptor(EGFR), which was indicated that the anti-CRC effect of AR-CR-PR was presumedly achieved by regulating tumor cell proliferation, apoptosis, migration, and angiogenesis through PI3 K-AKT, MAPK and other signaling pathways. The results of molecular docking showed that the nine core components had strong binding abilities to AKT1 and MAPK3. The results in vivo showed that AR-CR-PR could reduce the volume of the orthotopic tumor, inhibit liver metastasis, and decrease the phosphorylation of AKT1 and MAPK3 in the CRC model. The mechanism of AR-CR-PR in the intervention of CRC may be related to the activation of PI3 K-AKT and MAPK signaling pathway. This study provides a scientific basis for the clinical application of AR-CR-PR in the treatment of CRC and ideas for modern research on AR-CR-PR.

ABSTRACT

Astragali Radix-Curcumae Rhizoma(AR-CR) is a combination commonly used in the clinical treatment of tumors. Based on the T helper 17(Th17)/regulatory T cell(Treg) balance, the present study explored the possible mechanism of AR-CR combined with 5-fluorouracil(5-FU) on the tumor growth of orthotopic xenograft model mice of colorectal carcinoma. Ninety male BALB/c mice were randomly divided into nine groups, i.e., a blank group, a model group, a 5-FU group, high-, medium-, and low-dose AR-CR(2∶1) groups, and high-, medium-, and low-dose AR-CR+5-FU groups, with 10 mice in each group. The orthotopic xenograft model of CT26.WT colorectal carcinoma was induced in mice except those in the blank group. Twenty-four hours after the ope-ration, mice in the blank group and the model group received normal saline by gavage(10 mL·kg~(-1), once per day), and those in the 5-FU group received 5-FU by intraperitoneal injection(25 mg·kg~(-1), once every other day). Mice in the AR-CR groups received AR and CR decoctions by gavage(12, 6, and 3 g·kg~(-1), once a day) and those in the combination groups received AR and CR decoctions and 5-FU(doses and administration methods were the same as above). After intervention for three weeks, all mice were sacrificed and tumor tissues were collected. The tumor mass was weighed and the average tumor weight was calculated. The changing trend of Th17/Treg(%) in the CD4~+T lymphocytes of the spleen tissues of the mice in each group was detected. The mRNA expression in the blood and protein expression in the tumor tissues of transforming growth factor-β(TGF-β), tumor necrosis factor-α(TNF-α), interferon-γ(IFN-γ), Smad4, N-cadherin, matrix metalloproteinase-7(MMP-7) were detected. The experimental results revealed that compared with the model group, the groups with drug intervention showed reduced tumor mass(P<0.01), decreased CD4~+IL-17~+ in the spleen tissues to varying degrees(P<0.001), and increased proportion of CD4~+Foxp3~+(P<0.001 or P<0.05), indicating that Th17/Treg maintained dynamic balance, and the effect of the combination groups was predominant. Additionally, the mRNA expression in the blood and protein expression in the tumor tissues of TGF-β, TNF-α, IFN-γ, Smad4, N-cadherin, and MMP-7 declined to varying degrees in a dose-dependent manner(P<0.01 or P<0.001). The AR-CR combined with 5-FU can inhibit the tumor growth of orthotopic xenograft model mice of CT26.WT colorectal carcinoma. The mechanism may be related to maintenance of Th17/Treg dynamic balance in the body and down-regulation of TGF-β, TNF-α, IFN-γ, Smad4, N-cadherin, and MMP-7 expression.

ABSTRACT

Objective:To explore the application and effect of multidisciplinary collaboration in patients with tophi during perioperative period.Methods:Forty-five patients undergoing tophaceous gout surgery in our hospital from May to October 2020 were selected as the control group and treated with routine treatment.From November 2020 to April 2021, 41 patients undergoing tophaceous gout surgery in our hospital who were treated with multidisciplinary collaboration management mode were included as the intervention group. Postoperative pain, blood uric acid level, hospitalization expenses, hospitalization days and patient satisfaction were compared between the two groups.Results:After implementing the multidisciplinary integration man-agement mode, the pain score of the patients at 4 hours, 1 day and 3 days after operation was lower than that of the control group [(3.6±1.0) vs (4.1±1.0), t=2.33, P=0.022; (2.5±0.8) vs (3.0±0.6), t=3.85, P<0.001; (1.8±0.5) vs (2.2±0.7), t=3.52, P<0.001], the serum uric acid level was significantly lower than that of the control group at 1 month and 3 months after operation [(355±58) vs (3928±39), t=3.50, P=0.001; (316±48) vs (366±47), t=4.84, P<0.001], the hospitalization days and hospitalization expenses were significantly decreased [(8.90±2.48) d vs (10.62±3.96) d, t=2.44, P=0.017; (1.00±0.13) ten thousand yuan vs (1.11±0.17) ten thousand yuan, t=3.34, P=0.001], and the patient satisfaction was markedly improved (97.6% vs 82.2%, χ2=3.87, P=0.049). Conclusion:The multi-disciplinary collaboration mode in patients with tophi during perioperative period can effectively reduce the postoperative pain, improve the quality of care, promote reha-bilitation, improve the outcome, and reduce the economic burden of patients, which is worthy of popularization and being applied in clinic.

ABSTRACT

Objective:To evaluate the strategy and safety of the radiofrequency ablation (RFA) on ventricular arrhythmias (VAs) originating from the pulmonary sinus cusp (PSC) in pediatric patients.Methods:Retrospective study.Fifteen patients with VAs originating from the PSC who were intervened by RFA in the Department of Pediatric Cardiology, Guangdong Provincial People′s Hospital between March 2014 to July 2020 were enrolled.All the patients met the indication criteria for RFA in pediatric patients.The electrocardiogram, ablation method of ablation were analyzed.Different curved catheters were selected for RFA according to the age and weight of the patients.The catheter was then inserted in a " U" or inverted " P" shape to the PSC.The long-term effect of ablation were reviewed.Results:The mean age and body weight of 15 patients with VAs originating from the PSC were (11.6±2.6) (6-15) years and (39.9±12.2) (19-65) kg, respectively.The electrocardiogram recorded during VAs originating from the PSC showed left bundle branch block and inferior axis with monomorphic R pattern, as well as a QS-wave in aVR and aVL.The electrocardiogram characteristics varied in patients with VAs originating from the PSC.The ideal excitation point was not found in the right ventricular outflow tract or the ablation was unsuccessful in all patients, and the earliest target was mapped and RFA was successful.Among the 15 patients, the successful ablation site was in the lower regions of the PSC, involving the right cusp in 11 patients(73.3%), the anterior cusp in 3 patients(20.0%), and the left cusp in 1 patient(6.7%). The earliest potential recorded at the PSC ablation site preceded the QRS complex onset by (27.3±6.0) ms.During the follow-up period for (2.7±2.0) years, no recurrence of VAs or complications were recorded.Conclusions:Under the premise of gentle catheterization procedure and appropriate radiofrequency energy, ablation was effective, safe and with low recurrence rate to eradicate VAs originating from the PSC in children.

ABSTRACT

Substantial progress in the use of chemo-photodynamic nano-drug delivery systems (nano-DDS) for the treatment of the malignant breast cancer has been achieved. The inability to customize precise nanostructures, however, has limited the therapeutic efficacy of the prepared nano-DDS to date. Here, we report a structurally defined tandem-responsive chemo-photosensitive co-nanoassembly to eliminate primary breast tumor and prevent lung metastasis. This both-in-one co-nanoassembly is prepared by assembling a biocompatible photosensitive derivative (pheophorbide-diphenylalanine peptide, PPA-DA) with a hypoxia-activated camptothecin (CPT) prodrug [(4-nitrophenyl) formate camptothecin, N-CPT]. According to computational simulations, the co-assembly nanostructure is not the classical core-shell type, but consists of many small microphase regions. Upon exposure to a 660 nm laser, PPA-DA induce high levels of ROS production to effectively achieve the apoptosis of normoxic cancer cells. Subsequently, the hypoxia-activated N-CPT and CPT spatially penetrate deep into the hypoxic region of the tumor and suppress hypoxia-induced tumor metastasis. Benefiting from the rational design of the chemo-photodynamic both-in-one nano-DDS, these nanomedicines exhibit a promising potential in the inhibition of difficult-to-treat breast tumor metastasis in patients with breast cancer.

ABSTRACT

Objective:To analyze the effects of seasonal autoregressive integrated moving average model (SARIMA), generalized additive model (GAM), and long-short term memory model (LSTM) in fitting and predicting the incidence of hemorrhagic fever with renal syndrome (HFRS), so as to provide references for optimizing the HFRS prediction model.Methods:The monthly incidence data of HFRS from 2004 to 2017 of the whole country and the top 9 provinces with the highest incidence of HFRS (Heilongjiang, Shaanxi, Jilin, Liaoning, Shandong, Hebei, Jiangxi, Zhejiang and Hunan) were collected in the Public Health Science Data Center (https://www.phsciencedata.cn/), of which the data from 2004 to 2016 were used as training data, and the data from January to December 2017 were used as test data. The SARIMA, GAM, and LSTM of HFRS incidence in the whole country and 9 provinces were fitted with the training data; the fitted model was used to predict the incidence of HFRS from January to December 2017, and compared with the test data. The mean absolute percentage error ( MAPE) was used to evaluate the model fitting and prediction accuracy. When MAPE < 20%, the model fitting or prediction effect was good, 20%-50% was acceptable, and > 50% was poor. Results:From the perspective of overall fitting and prediction effect, the optimal model for the whole country and Heilongjiang, Shaanxi, Jilin, Liaoning and Jiangxi was SARIMA ( MAPE was 19.68%, 20.48%, 44.25%, 19.59%, 23.82% and 35.29%, respectively), among which the fitting and prediction effects of the whole country and Jilin were good, and the rest were acceptable. The optimal model for Shandong and Zhejiang was GAM ( MAPE was 18.29% and 21.25%, respectively), the fitting and prediction effect of Shandong was good, and Zhejiang was acceptable. The optimal model for Hebei and Hunan was LSTM ( MAPE was 26.52% and 22.69%, respectively), and the fitting and prediction effects were acceptable. From the perspective of fitting effect, GAM had the highest fitting accuracy in the whole country data, with MAPE = 10.44%. From the perspective of prediction effect, LSTM had the highest prediction accuracy in the whole country data, with MAPE = 12.23%. Conclusions:SARIMA, GAM, and LSTM can all be used as the optimal models for fitting the incidence of HFRS, but the optimal models fitted in different regions show great differences. In the future, in the establishment of HFRS prediction models, as many alternative models as possible should be included for screening to ensure higher fitting and prediction accuracy.

ABSTRACT

Objective:To analyze the clinical characteristics and risk factors associated with the formation of subcutaneous tophi among young gout patients.Methods:Gout patients treated at the Affiliated Hospital of Qingdao University from September 2016 to June 2020 were included. The clinical information was collected and relevant biochemical indices were detected. Fasting urine was collected to test urine pH value, urine uric acid and urine creatinine. Patients were divided into young tophi group and non-tophi group according to age. The measurement data of normal distribution was expressed as Mean±Standard deviation, and independent sample t test and one-way analysis of variance were used. The counting data was tested by Chi-square test. The risk factors were analyzed by logistic regression. Results:A total of 4 798 primary gout patients were collected. There were 915 patients with subcutaneous tophi, 2 308 young gout patients, 252 young gouty tophi patients among them. The average BMI, waist circumference, hip circumference, triglyceride level, serum uric acid level, glomerular filtration rate, alanineamino -transferase (ALT) and aspartate amino -transferase (AST) in the young tophi group were significantly higher than those in the middle-age tophi group ( F=46.074, 2.551, 9.203, 10.370, 15.118, 68.741, 35.023, 5.175, all P<0.05). Average age of disease onset, systolic blood pressure, fasting blood glucose, urine FEUA, Uua/Ucr and urea nitrogen level in young tophi group were significantly lower than those in middle-age tophi group ( F=474.876, 7.629, 6.441, 34.877, 3.633, 50.867, all P<0.05]. The age [(35±7) years old vs (33±7) years old], disease course [(7±4) years vs (4±3) years], blood pressure [(139±17) mmHg vs (135±16) mmHg], [(90±13) mmHg vs (86±12) mmHg], serum triglyceride [(2.6±2.1) mmol/L vs (2.4±2.0) mmol/L], total cholesterol [(4.9±1.4) mmol/L vs (4.6±1.4) mmol/L], serum uric acid [(547±171) μmol/L vs (490±160) μmol/L], urea nitrogen [(5.0±2.0) mmol/L vs (4.4±1.7) mmol/L], family history (27.0% vs 19.6%) and smoking rate(56.0% vs 48.9%) of tophi patients were significantly higher than those of non-tophi patients in young patients ( t=4.717, P<0.05; t=12.838, P<0.05; t=3.414, P<0.05; t=4.676, P<0.05; t=2.085, P<0.05; t=2.451, P<0.05; t=5.308, P<0.05; t=4.090, P<0.05; χ2=7.423, P<0.05; χ2=4.235, P<0.05) . The age of disease onset [(28±6) years vs (29±7) years] and glomerular filtration rate [(96±21) ml·min -1·1.73 m -2vs (103±21) ml·min -1·1.73 m -2] were statistically significantly lower than those of non-tophi patients ( t=-2.711, P<0.01; t=-4.907, P<0.01). Logistics regression analysis showed that age, course of disease, blood pressure, blood lipids level, serum uric acid level, family history of gout and smoking were risk factors for the formation of tophi in young people. After further adjusted for age, course of disease and family history of gout, it was found that serum uric acid, systolic blood pressure, diastolic blood pressure and urea nitrogen remined risk factors for tophi, while glomerular filtration rate remained a protective factor in young patients. Conclusion:Young tophi patients are always obese and have lipid metabolism disorder. Young patients with high level of serum uric acid and blood pressure, decreased renal function are prone to complicate with subcutaneous tophi. More attention should be paid in clinical practice to prevent or delay the formation of tophi.
