Objective To investigate the detection rate and related influencing factors of gastrointestinal diseases in grass-roots personnel.Methods A total of 481 grass-roots personnel were enrolled and examined by magnetic-controlled capsule endoscopy(MCCE).Multivariate logistic regression were used to analyze the influencing factors of gastrointestinal diseases detected by MCCE.Results All personnel completed MCCE,and gastrointestinal diseases were detected in 154(32.0%)cases,including 106 cases of erosive gastritis,25 cases of chronic atrophic gastritis,17 cases of digestive tract polyp,16 cases of gastric ulcer,5 cases of reflux esophagitis,4 cases of cardia,1 case of duodenitis,and 1 case of enteritis.Gastrointestinal diseases was correlated with special operation posts,long-term tasks within recent 6 months,abdominal distension,belching,nausea and vomiting,diarrhea and other symptoms(all P＜0.05).Multivariate logistic regression analysis showed that the risk factors of gastrointestinal diseases were working in special operation posts,performing long tasks within 6 months,belching,nausea and vomiting symptoms(all P＜0.05).Conclusion The overall detection rate of gastrointestinal diseases(mainly acid related diseases)is relatively high,and its incidence is closely related to working in special operation posts and performing long-term tasks within recent 6 months.Personnel working in special operation posts should be more alert to gastrointestinal diseases.Gastrointestinal symptoms have reference value for the prediction of lesions,but more attention should be paid to the identification of functional gastrointestinal diseases with endoscopy.

Objective To investigate the systemic immune-inflammation index(SII),albumin to globulin ratio(AGR),and high-sensitivity C-reactive protein(hs-CRP)in patients with ulcerative colitis(UC)compli-cated by Epstein-Barr virus(EBV)infection,and to evaluate their diagnostic value in UC complicated by EBV infection.Methods A total of 237 patients with UC admitted to the hospital from February 2024 to Septem-ber 2024.Patients were divided into a complicated group(150 cases)and a control group(87 cases)based on EBV-DNA test results.The counts of neutrophils,lymphocytes,and platelets,as well as the levels of albumin(ALB),globulin,hs-CRP,and erythrocyte sedimentation rate(ESR)were collected from the patients'routine blood tests,and the parameters of SII and AGR were calculated.Spearman correlation test was used for corre-lation analysis.Multivariate binary Logistic regression was used to analyze the influencing factors of EBV in-fection in UC patients,and receiver operating characteristic(ROC)curve was used to evaluate the diagnostic value of individual and combined detection of various indicators.Results There were statistically significant differences in disease activity,lesion range,ALB,AGR,ESR,hs-CRP,and SII between the complicated group and the control group(P<0.05).Correlation analysis showed that the positive copy number of EBV-DNA in the complicated group was positively correlated with disease activity,hs-CRP,and SII(P<0.05),and nega-tively correlated with ALB and AGR(P<0.05).Multivariate binary Logistic regression analysis indicated that SII and AGR were independent influencing factors for UC patients complicated by EBV infection.The combined detection of ALB,AGR,SII,hs CRP,ESR and various indicators has certain predictive value for UC patients with EBV infection.The area under the curve of the combined detection of ALB,AGR,SII,hs-CRP,ESR and the AUC of the combined detection of SII,AGR,hs-CRP were the largest,and the sensitivity and specificity were also high.Conclusion SII and AGR are independent influencing factors for UC patients com-plicated by EBV infection.The combined detection of SII,AGR,and hs-CRP has good diagnostic value for UC complicated by EBV infection and could serve as valuable biomarkers for evaluating UC complicated by EBV infection.

ObjectiveMetabolomics was used to reveal the mechanism of Aconiti Lateralis Radix Praeparata（ALRP） in attenuating toxicity by processing from the aspects of amino acid metabolism， oxidative stress and energy metabolism by analyzing multiple metabolic pathways. MethodTwenty-four rats were randomly divided into control group， raw group and processed group， 8 rats in each group. The raw and processed group were given with 0.64 g·kg^-1 of raw ALRP and processed ALRP respectively every day， the control group was given with an equal amount of normal saline once a day. After continuous administration for 7 days， the urine， serum and heart tissue of rats were collected. Pathological examination of the heart was carried out using hematoxylin-eosin（HE） staining， and the activities of lactate dehydrogenase（LDH） and creatine kinase-MB（CK-MB） in serum and cardiac tissues were detected by microplate assay and immunoinhibition assay. The effects of ALRP on rat heart before and after processing were compared and analyzed. Ultra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS） was used to perform urine metabolomics analysis， and multivariate statistical analysis was used to screen for differential metabolites related to ALRP in attenuating toxicity by processing， and pathway enrichment analysis was carried out to explore the processing mechanism. ResultHE staining showed that no obvious pathological changes were observed in the heart tissue of the control group， while obvious infiltration of inflammatory cells such as plasma cells and granulocytes was observed in the heart tissue of the raw group， indicating that the raw ALRP had strong cardiotoxicity. There was no significant difference in HE staining of heart tissue between the processed group and the control group， indicating that the toxicity of ALRP was significantly reduced after processing. Compared with the control group， the activities of LDH and CK-MB were significantly increased in serum and heart tissue of the raw group， and those were significantly decreased in serum and heart tissue of the processed group， suggesting that the myocardial toxicity of processed ALRP was reduced. A total of 108 endogenous differential metabolites associated with the raw ALRP were screened using multivariate statistical analysis in positive and negative modes， of which 51 differential metabolites were back-regulated by the processed ALRP. Biological analysis of the key regulatory pathways and associated network changes showed that the pathways related to toxicity of ALRP mainly included tryptophan metabolism， arginine and proline metabolism， phenylalanine metabolism， aminoacyl-tRNA biosynthesis， alanine， aspartate and glutamate metabolism， etc. The metabolic pathways related to the attenuation of processed ALRP mainly included aminoacyl-tRNA biosynthesis， tryptophan metabolism， phenylalanine， tyrosine and tryptophan biosynthesis， phenylalanine metabolism and caffeine metabolism. ConclusionThe processing technology of ALRP in Guilingji can significantly attenuate the cardiotoxicity of raw products， the mechanism mainly involves amino acid metabolism， oxidative stress and energy metabolism， which can provide experimental bases for the research related to the mechanism of toxicity reduction of ALRP by processing and its clinical safety applications.

In recent years， the incidence of pulmonary nodules has kept rising. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of pulmonary nodules and identify the breakthrough points of integrating TCM with Western medicine， the China Association of Chinese Medicine organized medical experts in TCM and western medicine to carry out in-depth discussion regarding this disease. The discussion encompassed the modern medical advances， TCM theories of etiology and pathogenesis， the role and advantages of TCM in the whole course management of pulmonary nodules， contents and methods of research on pulmonary nodules， and science popularization work， aiming to provide a reference for clinical practice and scientific research. After discussion， the experts concluded that the occurrence of pulmonary nodules was rooted in the deficiency of the lung and spleen and triggered by phlegm dampness， blood stasis， and Qi stagnation. TCM can treat pulmonary nodules by controlling and reducing nodules， improving physical constitution， ameliorating multi-system nodular diseases， reducing anxiety and avoiding excessive diagnosis and treatment， and serving as an alternative for patients who are unwilling or unfit for surgical treatment. At present， the optimal diagnosis and treatment strategy for pulmonary nodules has not been formed， which needs to be further studied from multiple perspectives such as clinical epidemiology， biology， and evidence-based medicine. The primary task of current research is to find out the advantages， effective prescriptions， and target populations and determine the effective outcomes of TCM in the treatment of pulmonary nodules. At the same time， basic research should be carried out to explore the etiology and biological behaviors of pulmonary nodules. The expert consensus on the diagnosis and treatment of pulmonary nodules with integrated TCM and Western medicine needs to be continuously revised to guide clinicians to conduct standardized， scientific， and accurate effective diagnosis and treatment.

ObjectiveTo analyze the satisfaction of service recipients with the preliminary assessment service of the unified elderly care needs evaluation in Shanghai， so as to provide reference for further optimization of the service system. MethodsA multi-stage random sampling method was employed to recruit participants. A total of 110 individuals who had received unified elderly care needs evaluation service in six districts of Shanghai were investigated using a structured questionnaire. SPSS 25.0 was used to analyze the data. Univariate analyses were conducted using the Chi-square test and Fisher’s precision probability test， while multivariate analysis was performed using ordinal regression. ResultsThere were differences in satisfaction with various aspects of the preliminary assessment process among participants from different areas， with those from outer suburbs generally exhibiting lower satisfaction （P<0.01）. Multivariate analysis results indicated that satisfaction with the timing of the preliminary assessment was related to the service recipients’ residential area and their primary source of income； satisfaction with the service attitude and capability of the assessment personnel was only related to the residential area. Satisfaction with the preliminary evaluation results was related to the participants’ marital status， educational level， income level， and the specific rating results. ConclusionThe satisfaction level with the preliminary assessment of the unified elderly care needs assessment in Shanghai is relatively high. In the process of evaluation， a deeper analysis and exploration of individual needs based on various personal information are essential to ensure the appropriateness of the provided elderly care services， and thereby effectively enhancing recipient satisfaction.

ObjectiveTo clarify the perception of the work and satisfaction levels among personnel conducting unified elderly care needs assessment in Shanghai， to analyze the factors influencing their job satisfaction， and to provide references for optimizing the job satisfaction of unified elderly care needs assessment personnel in Shanghai. MethodsA survey was conducted among 93 assessment personnel randomly selected from 29 elderly care needs assessment agencies in Shanghai. The personnel’s perception of their work and their levels of job satisfaction were examined. Chi-square test and Fisher’s precision probability test were used to compare regional differences， while the two-factor theory was employed to analyze the factors influencing job satisfaction. ResultsRegarding perception of the work， 92.5% of the surveyed personnel believed their work was important. Moreover， 87.1% were interested in their assessment tasks， and 84.9% believed they made a positive contribution to the assessment work and the assessment position was in line with their personal preferences. Regarding job satisfaction， 83.9% of the participants were satisfied with their assessment work， 78.5% considered the workload appropriate， and 74.2% found the working hours suitable. Additionally， 65.6% expressed satisfaction with the level of cooperation from the assessment subjects， while 94.6% and 91.4% of the personnel were satisfied with the support provided by the assessment agencies and had a sense of belonging， respectively. Furthermore， 65.6% of the personnel expressed satisfaction with their job compensation and benefits. Hygiene factors affecting job satisfaction included salary and compensation， workload， time spent on the job and institutional support related to external assistance， job suitability， teamwork， and client cooperation （P<0.05）， while motivational factors included recognition of the significance of the job， sense of achievement， interest in the job， sense of belonging， and opportunities for personal growth （P<0.05）. ConclusionThe overall work cognition and satisfaction of unified elderly care needs assessment personnel in Shanghai towards their work are relatively positive. Main issues include the heavy workload and actual job subsidies not meeting expectations. It is recommended to improve the standardization of the assessment process， establish a professional team of assessment personnel， and enhance the compensation and incentive mechanisms to continuously increase staff satisfaction.

Objective:To investigate the etiological distribution of severe community-acquired pneumonia (CAP) in children in Hebei Province.Methods:The nasopharyngeal swab samples and clinical data from 314 children with severe pneumonia were retrospectively analyzed between January 2014 and January 2016.Results:Among the 314 children, 298 (94.94%) showed positive result for pathogens in their nasopharyngeal swab samples, with 246 cases (78.34%) of multiple pathogens, predominantly mixed viruses and bacteria (206 cases, 65.61%). A total of 848 strains of pathogens were detected, including 483 strains (56.96%) of viruses, predominantly respiratory syncytial virus with 97 strains of subtype A and 86 strains of B. Bacteria and atypical pathogens ( Mycoplasma pneumoniae) had 365 strains (43.04%), mainly Streptococcus pneumoniae (220 strains) and Haemophilus influenzae (119 strains). The detection rate of pathogens was higher in children under one year of age ( χ2=21.389, P<0.001). There were no significant differences in different seasons, but the detection rates of respiratory syncytial virus A, respiratory syncytial virus B, and Streptococcus pneumoniae were higher in autumn, winter, and spring, respectively, with statistically significant differences ( χ2=22.205, P<0.001; χ2=37.874, P<0.001; χ2=11.380, P=0.009). Conclusions:Nasopharyngeal swab sample testing in children with severe pneumonia typically shows a coexistence of viral and bacterial pathogens, with detection rates varying among different age groups and seasons. Nasopharyngeal swab sample testing for pathogens provides valuable references for the identification of clinical pathogens.

Objective:To evaluate the impact of orthopedic robotic assistance and conventional freehand methods on surgical strategies, the safety of pedicle screw placement, and clinical efficacy in patients with upper cervical spine diseases.Methods:From January 2017 to March 2023, a total of 63 cases with upper cervical spine disease, were divided into two groups based on the screw placement technique: the robot-assisted pedicle screw placement (RA) group (41 cases) and the conventional freehand pedicle screw placement (CF) group (22 cases), were retrospectively included. These patients in the RA and CF groups underwent two types of posterior cervical surgery, including occipitocervical fusion (9 cases and 8 cases) and fixation and fusion of atlantoaxial and distal vertebrae (32 cases and 14 cases). The outcome parameters, including the disease course, surgical time, intraoperative blood loss, fluoroscopy frequency, radiation dose, hospital stay, treatment costs, complications, the rate of the pedicle screw placement, accuracy of upper cervical pedicle screw placement, and the risk factors that possibly affected the accuracy were recorded and analyzed. Postoperative follow-up was conducted for at least 6 months, and the efficacy of patients was assessed using imaging parameters, ASIS classification, VAS, and JOA scores.Results:Both groups had no screw-related complications and no spinal cord or vertebral artery injuries. In the RA group, the pedicle screw placement rates for the patients with occipitocervical fusion, and fixation and fusion of atlantoaxial and distal vertebrae were 100% (48/48) and 89.6% (138/154), respectively, far exceeding the placement rate in the CF group 42.9% (18/42) and 78.3% (54/69) (χ 2=37.403, P<0.001; χ 2=5.128, P=0.024). The fluoroscopic exposure dose and operation time of the two types of surgical patients in the RA group were both higher than those in the CF group ( P<0.05). Compared with the CF group, the accuracy of C 1 screws in the RA group increased from 42% (11/26) to 80% (51/64), with statistical significance (χ 2=13.342, P=0.004); while the accuracy of C 2 screws improved from 77% (33/43) to 88% (63/72) with no statistical difference (χ 2=2.863, P=0.413). Non-parametric correlation analysis found a significant correlation between the accuracy of C 1 and C 2 pedicle screw placement and the order of guide wire insertion in the RA group ( r=0.580, P<0.001; r=0.369, P=0.001). Postoperatively, both groups showed significant differences in cervicomedullary angle (CMA), Chamberlain angle (CL), McGregor angle, Boogard angle, Bull angle, clivus-canal angle (CCA), occipitocervical (C 0-C 2) angle, posterior occipitocervical angle (POCA), C 2-C 7 angle, and anterior atlantodental interval (ADI) ( P<0.05). The ASIA classification improved to varying degrees for both groups postoperatively, but there were no statistically significant differences between preoperative, postoperative, and last follow-up evaluations. VAS and JOA scores significantly improved for both groups postoperatively and at the last follow-up ( P<0.05). Conclusion:Both orthopedic robotic-assisted and conventional freehand pedicle screw placement techniques achieved satisfactory therapeutic effects in the treatment of upper cervical spine diseases. The orthopedic robot can effectively ensure the accuracy of upper cervical pedicle screw placement, the increase placement rate of pedicle screws in the upper cervical spine, and reduce fluoroscopy exposure. However, it is necessary to avoid the vertebral displacement caused by the priority insertion of the guide needle, which may affect the accuracy of subsequent planning.

Background and Objective Accurate diagnosis of mucous cystic lesion(PCL)remains a clinical difficult.Both Carcinoembryonic antigen(CEA)and glucose(GLU)are reported to have ability to distinguish mucinous PCL from non-mucinous PCL,but the accuracy was limited.The objective of this study was to evaluate the value of cystic CEA combined with GLU in the diagnosis of mucinous PCL.Methods PCL patients who underwent pancreatic surgery and endoscopic ultrasonography guided fine-needle aspiration(EUS-FNA)were retrospectively collected from the First Affiliated Hospital of Naval Medical University.Clinical data and cystic fluid analysis of included PCLs patients were analyzed using receiver operator(ROC)curves.ROC analysis,sensitivity and specificity analyses were used to evaluate the value of CEA combined with GLU in the diagnosis of mucinous PCL.Results From January 2015 to December 2021,a total of 84 patients underwent cyst fluid CEA and GLU analysis,of whom 44(52.4％)had mucinous PCL and 40(47.6％)had non-mucinous PCL.The AUC for distinguishing mucinous from non-mucinous PCL by CEA was 0.82[(95％confidence interval(CI):0.72-0.92)].When 192 ng/mL was used as the cutoff level,the diagnostic sensitivity and specificity were 50％and 93％,respectively.Using 20 ng/mL as cutoff level,the diagnostic sensitivity increased to 80％and the specificity decreased to 68％.The AUC for the cystic GLU to distinguish mucinous from non-mucinous PCL was 0.73(95％CI:0.99-0.87),and the diagnostic sensitivity and specificity were 100％and 60％,respectively.When the cutoff level of CEA was 192 ng/mL,the AUC of CEA combined with GLU in the diagnosis of mucinous PCLs was 0.94(95％Cl:0.86-0.99),while when the cutoff level of CEA was 20 ng/mL,the AUC of CEA combined with Glu in the diagnosis of mucinous PCLs was 0.94(95％CI:0.85-0.99).The AUCs were significantly higher than the AUC with single diagnostic indicators.Conclusion When using the cutoff level of 192 ng/mL,cyst fluid CEA combined with GLU has high sensitivity and specificity in differentiating mucinous PCL from non-mucinous PCL,so it can be considered for clinical application.Lower CEA cutoff level(20 ng/mL)can improve the sensitivity of diagnosis.
