Objective: To compare the effects of seasonal autoregressive integrated moving average (SARIMA) , seasonal autoregressive integrated moving average with exogenous regressors (SARIMAX) and long short-term memory neural network (LSTM) models in predicting the incidence of hand, foot, and mouth disease (HFMD). Methods: Monthly incidence data of HFMD in Kunming City from 2010 to 2019 were collected. SARIMA, SARIMAX and LSTM models were established using the monthly incidence of HFMD from 2010 to 2018 to predict the monthly incidence of HFMD from January to December 2019. The prediction performance of the three models was compared using mean squared error (MSE), root mean squared error (RMSE), mean absolute error (MAE) and mean absolute percentage error (MAPE). The optimal prediction model was selected based on the principle of minimizing MSE, RMSE, MAE and MAPE. Results: The HFMD cases were reported every month in Kunming City from 2010 to 2019, with the incidence fluctuating between 188.27/105 and 363.15/105. The disease exhibited a biennial high-incidence bimodal distribution. Among the four evaluation indicators for the training and testing sets, the LSTM model had the smaller values: MSE was 63.182 and 102.745, RMSE was 7.949 and 10.136, MAE was 6.535 and 7.620, and MAPE was 46.726% and 31.138%. The LSTM model performed the better, followed by the SARIMA model, while the SARIMAX model had the relatively poorest performance. Conclusion The LSTM model outperforms the SARIMA and SARIMAX models in predicting the incidence of HFMD.

ObjectiveTo investigate the association of SH2B1 rs7359397 （C>T） polymorphism with the progression to hepatic fibrosis in the elderly patients with metabolic dysfunction-associated steatotic liver disease （MASLD） in Beijing， China， and to provide an important genetic basis for the precise subtyping， prognostic evaluation， and individualized treatment of elderly MASLD patients in China. MethodsA total of 505 elderly patients （aged ≥65 years） who participated in regular physical examination in Mentougou Kuangshan Hospital of Beijing Jingmei Group General Hospital from November 2020 to September 2021 and were diagnosed with MASLD by abdominal ultrasound were enrolled as MASLD group， and 381 elderly population who underwent physical examination in the same community hospital during the same period of time and were not found to have MASLD by abdominal ultrasound were enrolled as control group. FibroScan was used to measure liver fat content and determine fibrosis stage. The 96-well microfluidic chip technique was used to identify SH2B1 rs7359397 polymorphism. The independent-samples t test was used for comparison of normally distributed continuous data between the two groups， and the chi-square test or the adjusted chi-square test was used for comparison of categorical data between the two groups. Univariate and multivariate Logistic regression analyses were used to identify the independent predictive factors for MASLD and its comorbidities. ResultsCompared with the control group， the MASLD group had a significantly younger age and significantly higher levels of waist circumference， hip circumference， waist-hip ratio， body mass index （BMI）， alanine aminotransferase， aspartate aminotransferase， triglyceride， platelet count， and fibrosis-4 （FIB-4） index， as well as a significantly lower level of high-density lipoprotein cholesterol （all P<0.05）. Among the 381 patients in the control group， 264 （69.29%） had genotype CC and 117 （30.71%） had genotype CT+TT， while among the 505 patients in the MASLD group， 317 （62.77%） had genotype CC and 188 （37.23%） had genotype CT+TT， suggesting that the MASLD group had a significantly higher proportion of patients with genotype CT+TT compared with the control group （χ²=4.09， P=0.043）. In the MASLD group， compared with the genotype CC group， the genotype CT+TT group had a significantly lower proportion of patients with FIB-4 ≥2 or atherosclerotic cardiovascular diseases （P<0.05）. The multivariate Logistic regression analysis showed that after adjustment for age， sex， and BMI， carrying T allele was a protective factor against progressive hepatic fibrosis （odds ratio ［OR］=0.481， 95% confidence interval ［CI］： 0.249 — 0.929， P=0.029）. In the subgroups of comorbidities with hypertension， metabolic syndrome， and obesity， genotype CT+TT was associated with a significant reduction in the risk of progressive hepatic fibrosis （hypertension： OR=0.27， 95%CI：0.09 — 0.77， P=0.014； metabolic syndrome： OR=0.30， 95%CI： 0.11 — 0.79， P=0.015； obesity： OR=0.11， 95%CI： 0.03 — 0.48， P=0.003）. After adjustment for age， sex， and BMI， in the patients with MASLD， the patients with genotype CT+TT had a significant reduction in the prevalence rate of atherosclerotic cardiovascular diseases compared with those with genotype CC （OR=0.506， 95%CI：0.336 — 0.761， P=0.001）. ConclusionSH2B1 rs7359397 （C>T） polymorphism is associated with the reduction in the risk of hepatic fibrosis and atherosclerotic cardiovascular diseases in MASLD patients.

Refeeding syndrome(RFS)has a high incidence among critically ill patients and significantly impacts the re-covery and prognosis of the patients.In this paper,we reviewed the literature on the risk factors and risk prediction models for RFS,finding the risk factors of RFS included patient-related,treatment-related factors and disease-related factors and the risk prediction models encompassed risk stratification model,risk score models and the Logistic regression models.It was concluded from the review that early assessment was crucial to preventing the occurrence of RFS.However,there was still a lack of reliable RFS risk prediction models with good predictive performance.It was found as well that it was crucial for the prevention of RFS to attach importance to nutritional and serological indicators and other factors.It was expected to be a necessity to conduct prospec-tive and multicenter studies to develop a risk prediction model for predicting RFS for ICU patients.Our review provides a refer-ence for early assessment and intervention for critically ill patients with RFS.

Objective:To identify the risk factors for postoperative pulmonary complications (PPCs) in pediatric patients undergoing malignant tumor resection.Methods:Medical records of pediatric patients who underwent open abdominal malignant tumor resection at Children′s Hospital affiliated to Zhejiang University School of Medicine from August 2019 to July 2023, with length of hospital stay ≥48 h, were retrospectively collected. Patients were divided into PPC group and non-PPC group based on the occurrence of PPCs within 7 days postoperatively. Variables with P<0.05 in the univariate analysis were included in the binary logistic regression analysis to identify the risk factors for PPCs. Results:A total of 605 pediatric patients who underwent abdominal malignant tumor resection were finally included, among which 391 children developed PPCs, with an incidence of 64.6%. Binary logistic regression analysis showed that body weight ( P=0.001), American Society of Anesthesiologists Physical Status classification ( P<0.001), preoperative hypoalbuminemia ( P=0.013), preoperative chemotherapy ( P=0.003), tumor compression/encasement of major abdominal vessels ( P=0.002), anesthesia duration ( P<0.001), intraoperative fluid intake (ml·kg -1·h -1, P<0.001), intraoperative use of hypotensive agents ( P=0.047), and concurrent resection of mediastinal tumors via abdominal approach ( P<0.001) were risk factors for PPCs in children undergoing malignant tumor resection. Age ( P<0.001) was identified as a protective factor for PPCs. Conclusions:Body weight, American Society of Anesthesiologists Physical Status classification, preoperative chemotherapy, preoperative hypoalbuminemia, tumor compression/encasement of major abdominal vessels, anesthesia duration, intraoperative fluid intake, intraoperative use of hypotensive agents, and concurrent resection of mediastinal tumors via abdominal approach are risk factors for PPCs in pediatric patients undergoing open abdominal malignant tumor resection, whereas age is a protective factor for PPCs.

Objective To analyze the equity of the allocation of oral medical resources and the accessibility of health service capabilities in Wuhan. Methods The equity of oral medical resources was calculated with Gini coefficient and Theil index, accessibility was assessed by two-step floating catchment area model, and the spatial autocorrelation was used to study the high-low clustering of accessibility. Results The Gini coefficient of oral medical resources based on population level was around 0.3, and the Gini coefficient of oral medical resources based on geographic area was greater than 0.6. Theil index calculation results were similar. In terms of overall accessibility, the area with poor accessibility was 2,428 square kilometers, reaching 28.38% of the total area, while the area with better accessibility accounted for 14.18%. Conclusion The allocation of oral medical care resources based on population distribution was fairer and better than that based on geographic area. Moreover, the geographical accessibility varies greatly between regions, showing the characteristics of high-high cluster and low-low cluster.

Cordyceps sinensis(C.sinensis)is a widely used and highly valuable traditional Chinese medicine.Several dipeptides have been detected in C.sinensis,but current scientific knowledge of its chemical makeup remains limited.In this study,an improved approach that integrates offline two-dimensional liquid chromatography(2D LC)separation,precursor ion list,library screening,and diagnostic ion filtering was established to systematically screen and characterize dipeptides in C.sinensis.Offline 2D LC integrating hydrophilic interaction LC and reverse phase separations was established to eliminate interference and identify the target dipeptides.A library containing the potential 400 dipeptides was created,and a precursor ion list with all theoretical precursor ions was adopted to trigger the MS/MS scan with high sensitivity.To identify dipeptides,the type and connection sequence of amino acids were determined according to the product ions.Ile and Leu residues were differentiated for the first time according to the characteristic ion at m/z 69.07.Ultimately,170 dipeptides were identified or tentatively characterized from C.sinensis,and most are reported for the first time in this species herein.In addition,the identified dipeptides were also applied for discrimination among the three Cordyceps species,and 11 markers were identified.The obtained results provide a deeper understanding of the chemical basis of C.sinensis.

Objective:To study the efficacy and safety of early abdominal puncture drainage (APD) in severe acute pancreatitis (SAP).Methods:A retrospective study was conducted on 189 patients with SAP who were managed at the Department of Intensive Medicine of the Second Affiliated Hospital of Anhui Medical University from January 2013 to May 2020. According to whether ultrasound-guided APD was performed within one week after admission to ICU, these patients were divided into 2 groups: patients treated with APD (the APD group) and patients treated without APD (the non-APD group). Clinical data, including the acute physiological and chronic health status (APACHE) Ⅱ score, modified Marshall score, sequential organ failure evaluation (SOFA) score, and prognostic indicators including the retroperitoneal percutaneous drainage (PCD) rate and length of hospital stay, were compared between the two groups before and 1 week after surgery.Results:Of the 189 SAP patients in this study, there were 110 males and 79 females, aged (52.5±17.4) years old. On admission to ICU, the blood amylase, C-reactive protein, procalcalonin, interleukin-6, APACHE II score, modified Marshall score and SOFA score in the APD group were significantly higher than those in the non-APD group. After 1 week of treatment, most clinical indicators in the 2 groups were significantly improved, and there were no significant differences between these indicators (all P>0.05). There were no significant differences in the abdominal infection, retroperitoneal PCD and mortality rates between the APD group and the non-APD group ( P>0.05). The length of hospital stay [29 (18, 45) vs 21 (15, 32) d] and ICU stay [5 (3, 11) vs. 7 (5, 17) d] in the APD group were significantly higher than those in the non-APD group ( P<0.05). Conclusion:For patients with SAP with peritoneal effusion, early APD effectively improved the condition and prognosis without increasing the peritoneal infection and mortality rates.
