To explore the variation laws of volatile oil during the extraction process of Artemisiae Argyi Folium and its impact on the quality of the medicinal solution, as well as to achieve precise control of the extraction process, this study employed headspace solid phase microextraction gas chromatography-mass spectrometry(HS-SPME-GC-MS) in combination with multiple light scattering techniques to conduct a comprehensive analysis, identification, and characterization of the changes in volatile components and the physical properties of the medicinal solution during the extraction process. A total of 82 volatile compounds were identified using the HS-SPME-GC-MS technique, including 21 alcohols, 15 alkenes, 14 ketones, 9 acids, 6 aldehydes, 5 phenols, 3 esters, and 9 other types of compounds. At different extraction time points(15, 30, 45, and 60 min), 71, 72, 64, and 44 compounds were identified in the medicinal solution, respectively. It was observed that the content of volatile components gradually decreased with the extension of extraction time. Through multivariate statistical analysis, four compounds with significant differences during different extraction time intervals were identified, namely 1,8-cineole, terpinen-4-ol, 3-octanone, and camphor. RESULTS:: from multiple light scattering techniques indicated that at 15 minutes of extraction, the transmittance of the medicinal solution was the lowest(25%), the particle size was the largest(0.325-0.350 nm), and the stability index(turbiscan stability index, TSI) was the highest(0-2.5). With the extension of extraction time, the light transmittance of the medicinal solution improved, stability was enhanced, and the particle size decreased. These laws of physicochemical property changes provide important basis for the control of Artemisiae Argyi Folium extraction process. In addition, the changes in the bioactivity of Artemisiae Argyi Folium extracts during the extraction process were investigated through mouse writhing tests and antimicrobial assays. The results indicated that the analgesic and antimicrobial effects of the medicinal solution were strongest at the 15-minute extracting point. In summary, the findings of this study demonstrate that the content of volatile oil in Artemisiae Argyi Folium extracts gradually decreases with the extension of extraction time, and the variation in volatile oil content directly influences the physicochemical properties and pharmacological efficacy of the medicinal solution. This discovery provides important scientific reference for the optimization of Artemisiae Argyi Folium extraction processes and the development and application of process analytical technologies.

Objective To investigate disease characteristics and hospitalization costs of children with Mycoplasma Pneumoniae pneumonia(MPP)admitted to Shanghai municipal medical hospitals from 2019 to 2023.Methods Depending on the Shanghai Municipal Hospital Pediatric Alliance,we retrospectively investigated community acquired MPP pediatric patients hospitalized in 22 municipal hospitals with pediatric qualifications(including 4 children's hospitals)in Shanghai from Jan 2019 to Dec 2023.We collected the patients'diagnosis codes,gender,age,length of hospital stay,hospitalization costs,and whether they progressed to severe Mycoplasma pneumoniae pneumonia(SMPP).Results From 2019 to 2023,a total of 29 045 hospitalized children with MPP were treated,with 6 035 cases(20.8%)identified as SMPP in the 22 hospitals.Trend analysis revealed a rising trend with years in the proportion of SMPP patients(χ2trend=365.498,P<0.001).Among the 4 children's hospitals,there were 18 710 cases with MPP,including 4 078 cases(21.8%)of SMPP.The proportion of SMPP patients also showed an increasing trend with years(χ2trend=14.548,P<0.001),and the proportion in 2023(23.0%)was higher than that in previous years with statistical significance.There were statistical differences in the seasonal distribution of MPP cases between different years,with higher proportions in summer and autumn overall.The age distribution of hospitalized MPP children varied among different years,with school-age children accounting for the majority(56.8%)in 2023.There was no difference in the distribution of severe cases between different genders,but there were differences in the proportion of severe cases among different age groups in different years,with a gradual increase in severe cases among children aged 1 to 3 years(χ2trend=191.567,P<0.001).The average length of hospital stay for MPP during the epidemic was higher than that during non-epidemic periods,and there were statistically significant differences in the average length of hospital stay between different years(P<0.001).The individual hospitalization costs during the epidemic were higher than in other years,and there were statistically significant differences in individual hospitalization costs between different years(P<0.001).The total hospitalization costs were still higher in 2019 and 2023.The individual hospitalization costs for SMPP were higher than for non-SMPP cases.Conclusion MPP outbreaks occurred in Shanghai in 2019 and 2023,with the higher proportions in summer and autumn overall.Compared to previous years,the number of hospitalized MPP children in Shanghai was higher in 2023,with a higher proportion of SMPP cases,especially among children under 3 years old.The individual per capita hospitalization expenses for SMPP cases were higher than for non-SMPP cases.

Objective To understand the prevalence status quo of mild cognitive impairment(MCI)in the elderly people by conducting the investigation on the elderly people in somewhere,and to explore the influ-encing factors of MCI in the elderly people to provide reference for constructing the MCI localized computer screening and diagnosis system in the elderly.Methods A multi-stage sampling method was used to deter-mine the survey population.The self-made questionnaires,mini mental state examination(MMSE),geriatric depression screening scale(GDS-15),geriatric anxiety screening scale,geriatric psychiatric symptoms scale,and daily living ability scale were used to collect or evaluate basic information,cognitive impairment,depres-sion,anxiety,psychiatric symptoms,and daily living ability of elderly people from March 5,2022 to July 22,2022.The index system affecting MCI was screened by the receiver operating characteristic(ROC)curve and unconditional binary logistic regression,and the localized computer screening diagnosis system was construc-ted.Results A total of 1 004 elderly individuals were surveyed,among them there were 262 cases(26.1％)of MCI,194 cases(19.3％)of anxious state,21 cases(2.1％)of depression,313 cases(31.2％)of psychotic symptoms and 32 cases(3.2％)of impaired ability of activities of daily living(ADL).The ROC curve analysis showed that the area under the curves(AUC)of depression,anxiety and psychotic symptoms for predicting MCI in elderly individuals were 0.640,0.645,and 0.586,respectively.AUC of anxiety combined with depres-sion(anxiety+depression),depression+psychotic symptoms,anxiety+psychotic symptoms and depression+anxiety+psychotic symptoms were 0.676,0.652,0.645 and 0.676,respectively.The multivariate analysis found that the age,whether or not anyone close to you died in the last two years,ability of activities of daily living,anxiety degree,whether or not having psychotic symptoms,education level,whether or not having joint habitation with the family members and suffering from multiple chronic diseases were the influencing factors of MCI.Conclusion The age,education level,death of close persons in the past two years,ability to live daily life,depression,and psychotic symptoms could serve as the indicators system of the MCI localized computer screening and diagnosis system.

Objective To analyze the stress changes of thoracic vertebra(T)11-sacrum(S)titanium rods in patients with ankylosing spondylitis after vertebral column decancellation(VCD)osteotomy,and provide reference for the selection and improvement of titanium rods before surgery.Methods The original data of the continuous scanning tomographic images of patients with ankylosing spondylitis after VCD osteotomy were imported into Mimics 21.0 in DICOM format,and T11-S vertebrae,screws and titanium rods were respectively reconstructed.They were imported into 3-Matic to establish a preliminary geometric modeling,and then processed with noise removal,paving,smoothing,etc.The improved model was imported into Hypermesh 10 software for grid division,and the material was imported into ANSYS 19.2 to display the finite element model after attribute assignment,Set the boundary and load conditions,and measure the stress value at the connection between the screw and the titanium rod.Results Under neutral position,forward bending,lateral bending,and axial rotation conditions,the titanium rod had the highest stress at the upper vertebrae(T11)and the lowest stress at the top vertebrae(L3);Under the backward extension condition,the titanium rod has the highest stress at the lower end vertebra(L5).Conclusion In the upper and lower vertebrae,it is possible to consider increasing the diameter of the titanium rod,enhancing its hardness,or changing it to a double rod.

Objective To investigate the effect of microRNA(miR)-4645-5p on the proliferation,invasion and epithelial-mesenchymal transition of esophageal cancer cells by targeting mucin 16(MUC16)and its mo-lecular mechanism.Methods The expression of miR-4645-5p in esophageal cancer tissues was analyzed online by TCGA database.The expression level of miR-4645-5p in esophageal cancer cell lines was analyzed by fluo-rescent real-time fluorescence quantitative polymerase chain reaction(qPCR).KYSE-30 cells were transfected with miR-4645-5p mimic and negative control mimic by lipofection technology,and were divided into miR-4645-5p group and control mimic group.The proliferation ability,migration ability and invasion ability of transfected KYSE-30 cells were analyzed by CCK-8 method,scratch test and Transwell test respectively.The target gene of miR-4645-5p was predicted by the bioinformatics website,and the binding of miR-4645-5p to the target gene was detected by the dual-luciferase reporter gene assay.The expression level of MUC16 mR-NA was detected by qPCR,and the protein expression levels of MUC16,transcription factor-1(ZEB-1),zonal atresia protein(ZO-1),tight junction protein-1(Claudin-1)and α-smooth muscle actin(α-SMA)were detected by Western blotting.Results The expression level of miR-4645-5p in esophageal cancer tissues was signifi-cantly lower than that in adjacent tissues(P＜0.01).Compared with HET-1 A,the expression of miR-4645-5p was lower in esophageal cancer cell lines(P＜0.05).After overexpression of miR-4645-5p,the proliferation a-bility of KYSE-30 cells was significantly reduced(P＜0.05),the migration ability was significantly reduced(P＜0.01)and the invasion ability was significantly reduced(P＜0.01).miR-4645-5p targeted and negatively regulated the expression of MUC16 mRNA(P＜0.01).After overexpression of miR-4645-5p,the protein ex-pression levels of MUC16,ZEB-1 and α-SMA were all down-regulated,and the protein expression levels of ZO-1 and Claudin-1 were up-regulated.Conclusion miR-4645-5p regulates the malignant biological behavior of esophageal cancer KYSE-30 cells by targeting MUC16.

Objective China is among the 30 countries with a high burden of tuberculosis(TB)worldwide,and TB remains a public health concern.Kashgar Prefecture in the southern Xinjiang Autonomous Region is considered as one of the highest TB burden regions in China.However,molecular epidemiological studies of Kashgar are lacking. Methods A population-based retrospective study was conducted using whole-genome sequencing(WGS)to determine the characteristics of drug resistance and the transmission patterns. Results A total of 1,668 isolates collected in 2020 were classified into lineages 2(46.0%),3(27.5%),and 4(26.5%).The drug resistance rates revealed by WGS showed that the top three drugs in terms of the resistance rate were isoniazid(7.4%,124/1,668),streptomycin(6.0%,100/1,668),and rifampicin(3.3%,55/1,668).The rate of rifampicin resistance was 1.8%(23/1,290)in the new cases and 9.4%(32/340)in the previously treated cases.Known resistance mutations were detected more frequently in lineage 2 strains than in lineage 3 or 4 strains,respectively:18.6%vs.8.7 or 9%,P<0.001.The estimated proportion of recent transmissions was 25.9%(432/1,668).Multivariate logistic analyses indicated that sex,age,occupation,lineage,and drug resistance were the risk factors for recent transmission.Despite the low rate of drug resistance,drug-resistant strains had a higher risk of recent transmission than the susceptible strains(adjusted odds ratio,1.414;95%CI,1.023-1.954;P = 0.036).Among all patients with drug-resistant tuberculosis(DR-TB),78.4%(171/218)were attributed to the transmission of DR-TB strains. Conclusion Our results suggest that drug-resistant strains are more transmissible than susceptible strains and that transmission is the major driving force of the current DR-TB epidemic in Kashgar.

Objective To investigate the predictive value of serum procalcitonin(PCT),interleukin-6(IL-6),C-reactive protein/albumin(CRP/ALB)and microRNA-335-5p(miR-335-5p)for bowel obstruction after colorectal cancer(CRC)surgery.Methods A total of 100 CRC patients admitted to the hospital and under-went surgical treatment from July 2022 to July 2023 were selected to observe whether intestinal obstruction occurred in patients 1 week after surgery,and they were divided into the intestinal obstruction group(13 ca-ses)and the non-intestinal obstruction group(87 cases)according to the occurrence of intestinal obstruction.The clinical data and serum PCT,IL-6,CRP/ALB,miR-335-5p levels of the two groups were compared,and Multivariate Logistic regression was used to analyze the risk factors for the occurrence of intestinal obstruc-tion after CRC surgery.The predictive value of serum PCT,IL-6,CRP/ALB,miR-335-5p for the occurrence of intestinal obstruction after CRC surgery was analyzed.Results Postoperative serum PCT,IL-6,CRP/ALB and miR-335-5p levels were higher than the preoperative levels in CRC patients(P＜0.05).Among 100 pa-tients for CRC surgery,a total of 13(13.00％)d eveloped intestinal obstruction within 2 weeks after surgery.The proportions of rectal tumor and clinical stage Ⅲ、miR-335-5p were higher in the intestinal obstruction group than those in the non-intestinal obstruction group,and the proportion of laparoscopic surgery was lower than that in the non-intestinal obstruction group(P＜0.05).Serum PCT,IL-6,and CRP/ALB levels were higher in the intestinal obstruction group than those in the non-intestinal obstruction group,miR-335-5p level was lower than that in the non-intestinal obstruction group(P＜0.05).Serum PCT,IL-6 and CRP/ALB were independent risk factors for the occurrence of intestinal obstruction after CRC surgery(P＜0.05),and miR-335-5p was a protective factor(P＜0.05).The area under the curve(AUC)of serum PCT,IL-6,CRP/ALB,miR-335-5p and the combined detection for predicting the occurrence of intestinal obstruction after CRC sur-gery was 0.818,0.805,0.862,0.938,and 0.980,and AUC of the combined detection was higher than that of single detection(ZPCT-combined detection-2.193,ZIL-6 combined detection-2.210,Z CRP/ALB combined detection=2.188,ZmiR-335-5p combined detection=2.437,P＜0.05).Conclusion Postoperative serum PCT,IL-6,CRP/ALB and miR-335-5p of CRC patients have a certain predictive value for the occurrence of intestinal obstruction in patients,and the combined detection could largely improve the accuracy of predicting the occurrence of postoperative intes-tinal obstruction.

Objective:To investigate the predictive role of relative diffusion-weighted imaging (DWI) signal intensity (DWI-rSI) in outcome in patients with anterior circulation large vessel occlusion cardioembolic stroke and successful recanalization after endovascular therapy (EVT).Methods:Patients with anterior circulation large vessel occlusion stroke due to cardioembolic embolism underwent EVT and successful recanalization at the Affiliated Hospital of Yangzhou University from March 2017 to March 2023 were retrospectively included. According to the modified Rankin Scale score 3 months after procedure, the patients were divided into a good outcome group (0-2 points) and a poor outcome group (3-6 points). Multivariate logistic regression analysis was used to identify independent predictive factors for poor outcome. Results:A total of 59 patients were enrolled, including 29 males (49.2%), median age of 74 years (interquartile range, 68-80 years). The median baseline National Institutes of Health Stroke Scale (NIHSS) score was 15 (12-21), and the median DWI Alberta Stroke Program Early CT Score (ASPECTS) was 8 (5-9). Thirty-two patients (54.2%) had good outcome, and 27 (45.8%) had poor outcome. Among them, 9 patients (15.3%) died (6 died from cerebral herniation after malignant brain edema, 2 died from complications, and 1 died from severe intracranial hemorrhage after procedure). Twenty-one patients (35.6%) experienced hemorrhagic transformation, including 12 (20.3%) with symptomatic intracranial hemorrhage. There were significant differences in baseline systolic blood pressure, NIHSS score, DWI-ASPECTS, DWI-rSI, and incidence of symptomatic intracranial hemorrhage between the good outcome group and the poor outcome group (all P<0.05). Multivariate logistic regression analysis showed that baseline systolic blood pressure (odds ratio 0.977, 95% confidence interval 0.919-0.991; P=0.015) and DWI-rSI (odds ratio 11.809, 95% confidence interval 1.932-72.170; P=0.008) were the independent predictors for poor outcome. Conclusion:DWI-rSI can predict the outcome of patients with anterior circulation large vessel occlusion cardioembolic stroke and successful recanalization after EVT.
