[Objective] To analyse and predict the tendencies of using erythrocyte blood in Changsha based on the autoregressive integrated moving average (ARIMA) model, long short-term memory (LSTM) and ARIMA-LSTM combination model, so as to provide reliable basis for designing a feasible and effective blood inventory management strategy. [Methods] The data of erythrocyte usage from hospitals in Changsha between January 2012 and December 2023 were collected, and ARIMA model, LSTM model and ARIMA-LSTM combination model were established. The actual erythrocyte consumption from January to May 2024 were used to assess and verify the prediction effect of the models. The extrapolation prediction accuracy of the models were tested using two evaluation indicators: mean absolute percentage error (MAPE) and root mean square error (RMSE), and then the prediction performance of the model was compared. [Results] The RMSE of LSTM model, optimal model ARIMA(1,1,1)(1,1,1)12 and ARIMA-LSTM combination model were respectively 5 206.66, 3 096.43 and 2 745.75, and the MAPE were 18.78%,11.54% and 9.76% respectively, which indicated that the ARIMA-LSTM combination model was more accurate than the ARIMA model and LSTM model, and the prediction results was basically consistent with the actual situation. [Conclusion] The ARIMA-LSTM model can better predict the clinical erythrocyte consumption in Changsha in the short term.

In recent years, the worldwide incidence rate of peripheral arterial and aortic diseases has increased year by year, significantly increasing the cardiovascular mortality and incidence rate of the whole population. In the past, peripheral arterial and aortic diseases were often more prone to missed diagnosis and delayed treatment compared to coronary artery disease. The 2024 ESC guidelines for the management of peripheral arterial and aortic diseases for the first time combines peripheral arterial and aortic diseases, integrating and updating the 2017 guidelines for peripheral arterial disease and the 2014 guidelines for aortic disease. The aim is to provide standardized recommendations for the management of systemic arterial diseases, ensuring that patients can receive coherent and comprehensive diagnosis and treatment, thereby improving prognosis. This article interprets the main content of the guideline in order to provide reference and assistance for the clinical diagnosis and treatment of peripheral arterial and aortic diseases in China at the current stage.

OBJECTIVES:
To investigate the clinicopathological characteristics and prognostic factors of pediatric Hodgkin lymphoma (HL).
METHODS:
A retrospective analysis was conducted on the clinical data of children with newly diagnosed HL from January 2011 to December 2023 at four hospitals: Fujian Medical University Union Hospital, Fujian Medical University Zhangzhou Hospital, First Affiliated Hospital of Xiamen University, and Fujian Children's Hospital. Patients were categorized into low-risk (R1), intermediate-risk (R2), and high-risk (R3) groups based on HL staging and pre-treatment risk factors. The patients received ABVD regimen or Chinese Pediatric HL-2013 regimen chemotherapy. Early treatment response and long-term efficacy were assessed, and prognostic factors were analyzed using the Cox proportional hazards regression model.
RESULTS:
The overall complete response (CR) rates after 2 and 4 cycles of chemotherapy were 42% and 68%, respectively. Compared with the ABVD regimen group, patients treated with the HL-2013 regimen in the R1 group showed significantly higher CR rates after both 2 and 4 cycles (P<0.05). However, no statistically significant differences in CR rates were observed between the two regimens in the R2 and R3 groups (P>0.05). The 5-year event-free survival (EFS) rate, overall survival rate, and freedom from treatment failure rate were 83%±4%, 97%±2%, and 88%±4%, respectively. Cox analysis indicated that the presence of a large tumor mass at diagnosis and failure to achieve CR after 4 cycles of chemotherapy were independent risk factors for lower EFS rates (P<0.05).
CONCLUSIONS
Pediatric HL generally has a favorable prognosis. The presence of a large tumor mass at diagnosis and failure to achieve CR after 4 cycles of chemotherapy indicate poor prognosis.

Cholangiocarcinoma (CCA) is a malignant tumor originating from cholangiocytes. However, it remains unclear about the pathogenesis of this carcinoma, which may be related to multiple factors. Currently, CCA is mainly treated by surgery, chemotherapy, and radiotherapy. Among them, surgery is the only potentially curative option for CCA. Nevertheless, the high malignancy and asymptomatic nature of CCA may lead to poor treatment outcomes. It has been demonstrated that Chinese medicine (CM) plays a significant role in various antitumor applications. Meanwhile, CM exhibits fewer side effects and high availability. Moreover, the in vitro application of CM monomers has been explored in many domestic and foreign studies. This article mainly reviews the signaling pathways and molecular mechanisms of CM monomers in the treatment of CCA in recent years. These findings are expected to provide new insights into the treatment of CCA.

OBJECTIVE:
To analyze the clinical characteristics of elderly patients with sepsis, identify the key factors affecting their clinical outcomes, construct a death risk assessment scale for elderly patients with sepsis, and evaluate its predictive value.
METHODS:
A retrospective case-control study was conducted. The clinical data of sepsis patients admitted to intensive care unit (ICU) of the First Affiliated Hospital of Wenzhou Medical University from September 2021 to September 2023 were collected, including basic information, clinical characteristics, and clinical outcomes. The patients were divided into non-elderly group (age ≥ 65 years old) and elderly group (age < 65 years old) based on age. Additionally, the elderly patients were divided into survival group and death group based on their 30-day survival status. The clinical characteristics of elderly patients with sepsis were analyzed. Univariate and multivariate Logistic regression analyses were used to screen the independent risk factors for 30-day death in elderly patients with sepsis, and the regression equation was constructed. The regression equation was simplified, and the death risk assessment scale was established. The predictive value of different scores for the prognosis of elderly patients with sepsis was compared.
RESULTS:
(1) A total of 833 patients with sepsis were finally enrolled, including 485 in the elderly group and 348 in the non-elderly group. Compared with the non-elderly group, the elderly group showed significantly lower counts of lymphocyte, T cell, CD8+ T cell, and the ratio of T cells and CD8+ T cells [lymphocyte count (×109/L): 0.71 (0.43, 1.06) vs. 0.83 (0.53, 1.26), T cell count (cells/μL): 394.0 (216.0, 648.0) vs. 490.5 (270.5, 793.0), CD8+ T cell count (cells/μL): 126.0 (62.0, 223.5) vs. 180.0 (101.0, 312.0), T cell ratio: 0.60 (0.48, 0.70) vs. 0.64 (0.51, 0.75), CD8+ T cell ratio: 0.19 (0.13, 0.28) vs. 0.24 (0.16, 0.34), all P < 0.01], higher natural killer cell (NK cell) count, acute physiology and chronic health evaluation II (APACHE II) score, ratio of invasive mechanical ventilation (IMV) during hospitalization, and 30-day mortality [NK cell count (cells/μL): 112.0 (61.0, 187.5) vs. 95.0 (53.0, 151.0), APACHE II score: 16.00 (12.00, 21.00) vs. 13.00 (8.00, 17.00), IMV ratio: 40.6% (197/485) vs. 31.9% (111/348), 30-day mortality: 28.9% (140/485) vs. 19.5% (68/348), all P < 0.05], and longer length of ICU stay [days: 5.5 (3.0, 10.0) vs. 5.0 (3.0, 8.0), P < 0.05]. There were no statistically significant differences in the levels of inflammatory markers such as C-reactive protein (CRP), procalcitonin (PCT), tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), and interleukins (IL-2, IL-4, IL-6, IL-10) between the two groups. (2) In 485 elderly patients with sepsis, 345 survived in 30 days, and 140 died with the 30-day mortality of 28.9%. Compared with the survival group, the patients in the death group were older, and had lower body mass index (BMI), white blood cell count (WBC), PCT, platelet count (PLT) and higher IL-6, IL-10, N-terminal pro-brain natriuretic peptide (NT-proBNP), total bilirubin (TBil), blood lactic acid (Lac), and ratio of in-hospital IMV and continuous renal replacement therapy (CRRT). Multivariate Logistic regression analysis indicated that BMI [odds ratio (OR) = 0.783, 95% confidence interval (95%CI) was 0.678-0.905, P = 0.001], IL-6 (OR = 1.073, 95%CI was 1.004-1.146, P = 0.036), TBil (OR = 1.009, 95%CI was 1.000-1.018, P = 0.045), Lac (OR = 1.211, 95%CI was 1.072-1.367, P = 0.002), and IMV during hospitalization (OR = 6.181, 95%CI was 2.214-17.256, P = 0.001) were independent risk factors for 30-day death in elderly patients with sepsis, and the regression equation was constructed (Logit P = 1.012-0.244×BMI+0.070×IL-6+0.009×TBil+0.190×Lac+1.822×IMV). The regression equation was simplified to construct a death risk assessment scale, namely BITLI score. Receiver operator characteristic curve (ROC curve) analysis showed that the area under the ROC curve (AUC) of BITLI score for predicting death risk was 0.852 (95%CI was 0.769-0.935), and it was higher than APACHE II score (AUC = 0.714, 95%CI was 0.623-0.805) and sequential organ failure assessment (SOFA) score (AUC = 0.685, 95%CI was 0.578-0.793). The determined cut-off value of BITLI score was 1.50, while achieving a sensitivity of 83.3% and specificity of 74.0%.
CONCLUSIONS
Elderly patients with sepsis often have reduced lymphocyte counts, severe conditions, and poor prognosis. BMI, IL-6, TBil, Lac, and IMV during hospitalization were independent risk factors for 30-day death in elderly patients with sepsis. The BITLI score constructed based above risk factors is more precise and reliable than traditional APACHE II and SOFA scores in predicting the outcomes of elderly patients with sepsis.

OBJECTIVE:
Chronic obstructive pulmonary disease (COPD) is a major health concern in northwest China; however, the impact of particulate matter (PM) exposure during sand-dust storms (SDS) remains poorly understood. Therefore, this study aimed to investigate the association between PM exposure on SDS days and COPD hospitalization risk in arid regions.
METHODS:
Data on daily COPD hospitalizations were collected from 323 hospitals from 2018 to 2022, along with the corresponding air pollutant and meteorological data for each city in Gansu Province. Employing a space-time-stratified case-crossover design and conditional Poisson regression, we analyzed 265,379 COPD hospitalizations.
RESULTS:
PM exposure during SDS days significantly increased COPD hospitalization risk [relative risk ( RR) for PM 2.5, lag 3:1.028, 95% confidence interval ( CI): 1.021-1.034], particularly among men and the elderly, and during the cold season. The burden of PM exposure on COPD hospitalization was substantially high in Northwest China, especially in the arid and semi-arid regions.
CONCLUSION
Our findings revealed a positive correlation between PM exposure during SDS episodes and elevated hospitalization rates for COPD in arid and semi-arid zones in China. This highlights the urgency of developing region-specific public health strategies to address adverse respiratory outcomes associated with SDS-related air quality deterioration.

Postoperative nausea and vomiting (PONV) are common complications that mainly occur within 24 h after orthognathic surgery. The incidence of nausea and vomiting after orthognathic surgery remains high and is a difficult problem for patients and surgeons. These complications not only affect wound healing and increase the risk of postoperative bleeding. Vomit and blood may also cause nausea and vomiting, which results in a vicious cycle. Frequent nausea and vomiting are a painful experience and more serious than postoperative pain. They are one of the main reasons for postoperative infection, delayed discharge, and increased hospitalization costs and affect patient satisfaction. In this review, the author combined literature review and clinical experience and summarized and analyzed the causes of orthognathic nausea and vomiting and prevention and treatment strategies to improving the related clinical process.

Objective:Farfarae Flos has the effect of cough suppression and phlegm elimination,with cough suppression as the main function.Studies have revealed that certain components of Farfarae Flos may be related to its cough suppressant effect,and some components have been confirmed to have cough suppressant activity.However,the antitussive material basis of Farfarae Flos has not been systematically elucidated.This study aims to elucidate the group of active ingredients in Farfarae Flos with cough suppressant activity by correlating the high performance liquid chromatography(HPLC)fingerprint of Farfarae Flos extract with its cough suppressant activity. Methods:HPLC was used to establish the fingerprint profiles of 10 batches of Farfarae Flos extract and obtain their chemical composition data.Guinea pigs were selected as experimental animals and the citric acid-induced cough model was used to evaluate the antitussive efficacy data of 10 batches of Farfarae Flos extract.SPF-grade healthy male Hartley guinea pigs were randomly divided into the S1 to S10 groups,a positive control group,and a blank control group(12 groups in total),with 10 guinea pigs in each group.The S1 to S10 groups were respectively administered Farfarae Flos extract S1 to S10(4 g/kg),the positive control group was administered pentoverine citrate(10 mg/kg),and the blank control group was administered purified water.Each group received continuous oral administration for 5 days.The guinea pigs were placed in 5 L closed wide-mouth bottles,and 17.5%citric acid was sprayed into the bottle with an ultrasonic atomizer at the maximum spray intensity for 0.5 minutes.The cough latency period and cough frequency in 5 minutes were recorded for each guinea pig.Grey relational analysis(GRA)and partial least squares regression(PLSR)were used to conduct spectral-effect correlation analysis of the chemical composition data of Farfarae Flos extract and the antitussive efficacy data,and predict the group of active ingredients in Farfarae Flos with antitussive activity.The bioequivalence verification was conducted to verify the predicted group of active ingredients in Farfarae Flos with antitussive activity:SPF-grade healthy male Hartley guinea pigs were randomly divided into a S9 group,an active ingredient group,a positive control group,and a blank control group(4 groups in total),with 10 guinea pigs in each group.The S9 group was administered Farfarae Flos extract S9(4 g/kg),the active ingredient group was administered the predicted combination of antitussive active ingredients(dose equivalent to 4 g/kg of Farfarae Flos extract S9),the positive control group was administered pentoverine citrate(10 mg/kg),and the blank control group was administered purified water.Each group received continuous oral administration for 5 days,and animal modeling and observation of efficacy indicators were the same as above. Results:The HPLC fingerprint of 10 batches of Farfarae Flos extract was established,and the peak area data of 14 main common peaks were obtained.The antitussive effect data of 10 batches of Farfarae Flos extract were obtained.Compared with the blank control group,the cough latence in the positive control group and S1,S2,S3,S4,S6,S7,S8,S9,S10 groups was prolonged(all P<0.01),while the cough frequency in 5 minutes in the positive control group and S1,S2,S4,S6,S8,S9,S10 groups was decreased(all P<0.05).The analysis of spectrum-effect relationship revealed that isochlorogenic acid C,isochlorogenic acid A,chlorogenic acid,isochlorogenic acid B,isoquercitrin,and rutin had high contribution to the antitussive effect of Farfarae Flos,and the 6 components were predicted to be the antitussive component group of Farfarae Flos.The verification of bioequivalence showed that there were no statistically significant differences in the antitussive effect between the S9 group and the antitussive component composition group(all P>0.05),which confirmed that isochlorogenic acid C,isochlorogenic acid A,chlorogenic acid,isochlorogenic acid B,isoquercetin,and rutin were the antitussive component group of Farfarae Flos. Conclusion:The analysis of spectrum-effect relationship combined with the verification of bioequivalence could be used to study the antitussive material basis of Farfarae Flos.The antitussive effect of Farfarae Flos is the result of the joint action of many components.

ObjectiveTo explore the scientific connotation of fried charcoal survivability of Lonicerae Japonicae Flos(LJF) by analyzing the correlation between the color change and the intrinsic components during the processing of LJF Carbonisata(LJFC), and taking pH, charcoal adsorption and microscopic characteristics as indexes. MethodLJFC samples with different degrees of processing were prepared according to the stir-frying time of 0.0, 1.5, 3.0, 4.5, 6.0, 7.5, 9.0, 10.5 min(numbered S1-S8), and the contents of gallic acid, chlorogenic acid, cryptochlorogenic acid, rutin, luteoloside, isochlorogenic acid A and isochlorogenic acid C were determined by high performance liquid chromatography(HPLC), and the L*(brightness), a*(red-greenness) and b*(yellow-blueness) of LJFC samples with different degrees of processing were determined by spectrophotometer, and the correlation analysis and principal component analysis(PCA) between the contents of seven representative components and the color of the samples were carried out by SPSS 26. 0 and SIMCA-P 14.1. Then pH, adsorption force and characteristic structure of different samples of LJFC were detected and the processing pattern of LJFC was analyzed. ResultThe results of quantitative analysis revealed that the contents of luteoloside, rutin, chlorogenic acid and isochlorogenic acid A gradually decreased, and the contents of cryptochlorogenic acid, isochlorogenic acid C and gallic acid firstly increased and then decreased. The L* and b* of the sample powders decreased, and a* showed a trend of increasing and then decreasing. The L* and b* were positively correlated with the contents of chlorogenic acid, rutin, luteoloside, isochlorogenic acid A, b* was positively correlated with the content of gallic acid, and a* was positively correlated with the contents of cryptochlorogenic acid and isochlorogenic acid C. PCA revealed that samples could be clearly divided into 3 groups, S1-S2 as one group, S3-S5 as one group, and S6-S8 as one group, with S3 having the highest score. The results of regression analysis showed that only isochlorogenic acid C could be used to predict the contents of components by colorimetric values combined with regression equations. Physicochemical analysis showed that pH of LJFC increased with the increase of degree of charcoal stir-frying, while adsorption force showed a tendency of increasing and then decreasing, with the highest adsorption force in the S5 sample, and the non-glandular hairs, calcium oxalate clusters and pollen grains had a varying degree of decreasing with the deepening of processing degree, and the microstructures of S6-S8 samples were obviously charred with pollen grains almost invisible. ConclusionThe changes in chemical composition and color characteristics of LJFC during the processing have certain correlations, combined with the changes in physicochemical properties, S5 sample is found to be the optimal processed products, which can provide a reference for the processing standardization and quality evaluation of LJFC, and enrich the scientific connotation of fried charcoal survivability of LJF.
