OBJECTIVE To evaluate the efficacy and safety of high-dose ilaprazole combined with amoxicillin for newly diagnosed elderly patients with Helicobacter pylori （Hp） infection， and analyze independent risk factors for failure of Hp infection eradication treatment. METHODS Totally 200 cases of newly diagnosed elderly patients with Hp infection in Xinxiang Central Hospital from August 1， 2021 to December 1， 2024 were selected and randomly divided into control group and study group， with 100 cases in each group. The control group was treated with classic quadruple therapy regimen （Amoxicillin capsules+ Clarithromycin tablets+Bismuth potassium citrate tablets+Ilaprazole enteric-coated tablets）. The study group was treated with high- dose Ilaprazole enteric-coated tablets+Amoxicillin capsules. All patients were administered medication for 2 weeks. Hp eradication rates in the two groups were compared using intention-to-treat （ITT） and per-protocol （PP） analyses. The incidence of adverse reactions in both groups was also recorded. The multiple-factor Logistic regression analysis was used to identify independent risk factors for failure of Hp infection eradication treatment. RESULTS In ITT and PP analyses， there was no significant difference of Hp eradication rates between the two groups （P＞0.05）. There was no significant difference in incidence of mild to moderate adverse reactions between the two groups （P＞0.05）. BMI ≤18.5 kg/m2， BMI ＞23.9 kg/m2， rural residence， concomitant diabetes and concomitant heart disease were identified as independent risk factors influencing the failure of Hp infection eradication treatment （P＜0.05）. CONCLUSIONS The efficacy and safety of high-dose ilaprazole combined with amoxicillin are comparable to classic quadruple therapy regimen in treating newly diagnosed elderly patients with Hp infection. Independent risk factors influencing the failure of Hp infection eradication treatment include BMI ≤18.5 kg/m2， BMI ＞23.9 kg/m2， rural residence， concomitant diabetes and concomitant heart disease.

Objective:To quantify the diagnostic index of probe-based confocal laser endomicroscopy (pCLE) for diagnosing Helicobacter pylori ( HP)-associated chronic atrophic gastritis (HpCAG), and to evaluate the efficacy of the quantified diagnostic index for HpCAG. Methods:The study was divided into two stages. The first stage prospectively included patients undergoing gastroscopy, endoscopic biopsy and 13C breath test from November 2021 to September 2022 at the Second Affiliated Hospital of Baotou Medical College. The capillary diameter (CD), cells spacing (CS), gland spacing (GS), and gland area (GA) in the pCLE field of offline video was measured with Image J. The diagnostic criteria of HpCAG by quantitative indicators under pCLE was established by analyzing the area under the receiver operating characteristic (ROC) curve (AUC). In the second stage, the cases with pCLE examination and 13C breath test at the Second Affiliated Hospital of Baotou Medical College from October 2021 to October 2022 were included. The cases that overlapped with the first stage were excluded. The trial was single-blind, with endoscopists and pathologists blind to each other's diagnoses. The diagnosis of pCLE was conducted according to the criteria obtained in the first stage, and the consistency between pCLE diagnosis and the results of histopathology and 13C breath test was analyzed. Results:The first stage enrolled 191 specimens from 35 patients. According to the pathological results of endoscopic biopsy and 13C breath test results, patients and gastric mucosa samples were divided into 4 groups, HP-positive CAG group ( n=59), HP-positive non-CAG group ( n=52), HP-negative CAG group ( n=40), and HP-negative non-CAG group ( n=40). ROC curve analysis results showed that in HP-positive patients, the optimal critical value of GS to distinguish between CAG and non-CAG gastric mucosa was 29.68 μm, and the AUC was the largest among the 4 parameters. In HP-negative patients, the optimal critical value of GS for distinguishing gastric mucosa from CAG and non-CAG was 23.57 μm, and the AUC was the largest among the 4 parameters. In patients with non-CAG, the optimal critical value for GS to distinguish HP-positive and HP-negative gastric mucosa was 20.57 μm, and the AUC was the largest among the 4 parameters. In patients with CAG, the optimal critical values of CD, CS, GS and GA to distinguish between HP-positive and HP-negative gastric mucosa were 13.23 μm, 1.38 μm, 34.03 μm and 6 066.5 μm 2, respectively, and the AUC were 0.608, 0.888, 0.849 and 0.900, respectively. Finally, GS was selected to distinguish between HpCAG and non-HpCAG gastric mucosa, and the optimal critical value was 31.71 μm. However, considering that it was difficult to measure the distance of 31.71 μm by the ruler below the image, the critical value was changed to 30 μm, so GS>30 μm was used as the diagnostic criteria for HpCAG in pCLE, and the diagnostic sensitivity and the specificity were 91.5% and 76.0%, respectively. In the second phase 224 specimens from 80 patients were observed. The sensitivity, the specificity, the positive predictive value, the negative predictive value and accuracy of pCLE (GS>30 μm) in the diagnosis of HpCAG were 96.5% (164/170), 88.9% (48/54), 96.5% (164/170), 88.9% (48/54) and 94.6% (212/224), respectively, with excellent diagnostic agreement with histopathology and 13C breath test (Kappa=0.854). Conclusion:The quantitative monitoring of gastric mucosal microstructure can be achieved under pCLE, and the quantifying indicators are helpful to improve the accuracy of HpCAG diagnosis.

Methods:Collect relevant data of malignant tumors in Gansu Province from 2015 to 2018,and calculate statistical indicators such as crude rates,age-specific rates,age-standardized rates,and cumulative rates(0-74 years old)stratified by gender,area,and age groups. Results:From 2015 to 2018,the crude incidence rate of malignant tumors in tumor registration areas of Gansu Province was 282.08/100 000(320.56/100 000 for male and 242.03/100 000 for female),and the age-standardized incidence rate by Chinese standard population in 2000(ASIRC)and the age-standardized incidence rate by Segi's world standard population(ASIRW)were 216.75/100 000 and 216.63/100 000,respectively.The crude mortality rate was 171.78/100 000(212.02/100 000 for male and 129.53/100000 for female),and the age-standardized mortality rate by Chinese standard population in 2000(ASMRC)and age-standardized mortality rate by Segi's world standard population(ASMRW)were 133.77/100000 and 131.65/100 000,respectively.The incidence and mortality of malignant tumors began to increase rapidly in the age group of 60-64 years,reached the peak in the age group of 80-84 years,and then decreased in the age group of≥85 years.The top 5 malignant tumors were gastric cancer,lung cancer,liver cancer,colorectal cancer,and esophageal cancer,with the top 10 malignant tumors accounting for 77.46%of all new cases;The top 5 deaths were gastric cancer,lung cancer,liver cancer,esophageal cancer,and colorectal cancer,with the top 10 malignant tumors accounting for 86.43%of all deaths. Conclusion:The burden of malignant in Gansu Province is still heavy.The incidence of tumors of the digestive systems,lung cancer and female breast cancer are still among the highest in Gansu Province.Primary prevention and secondary prevention approaches should be strengthened and cancer prevention and control models should be optimized according to the epidemological characteristics of malignant tumors,optimize cancer prevention and control models,in order to contribute to the implementation of healthy Gansu and healthy China strategies.

The computer network system is the core of a smart hospital,and the requirements for network architecture in the construction of large-scale smart hospitals are becoming increasingly high.Traditional network architectures with users moving with the network generally suffer from problems such as low installation efficiency,slow policy deployment speed,and easy confu-sion of asset accounts.When faced with complex network requirements in hospitals,they also face challenges such as poor net-work scalability and cumbersome management.Selecting appropriate network virtualization technology and building a new,high-speed,and reliable network architecture play a crucial role in promoting the development of large-scale smart hospitals.Starting from 2023,a large tertiary hospital in Guangzhou has built a new branch network project based on software-defined networking,showcasing the advantages of this architecture in terms of deployment speed,policy configuration,and endpoint management.Ex-perimental data ultimately shows that using a software-defined networking architecture can significantly improve the efficiency of policy deployment in hospital networks.

Schizophrenia is a severe mental illness with a significant disease burden.The interaction between oxidative stress and pro-inflammatory factors promotes chronic neuroinflammation and immune damage,leads to dysregulation of dopaminergic and glutamatergic pathways and occurrence of psychotic symptoms and is believed to be closely related to the pathogenesis of schizophrenia.In this paper,we aim to identify biomarkers within the tryptophan kynurenine metabolic pathway,the WNT/β-Catenin pathway and the NF-κB pathway,and dopamine metabolism.These pathways have been extensively studied and are known to be involved in the interac-tion between inflammation and oxidative stress.We will also explore the potential application of related antioxidants in the diagnosis and treatment of schizophrenia,summarizing their current research progress.

Purpose To explore the value of CT large reconstruction matrix 1024×1024 combined with iterative reconstruction algorithm Karl in the diagnosis of pulmonary nodules.Materials and Methods A total of 500 patients who underwent chest CT examination at the First Affiliated Hospital of Dalian Medical University from October 2021 to May 2022 were prospectively collected,and the raw data of CT scans were reconstructed to divide into group A and B.Group A was reconstructed using a conventional 512×512 matrix combined with Karl 5 reconstruction;group B was reconstructed using a large 1 024×1 024 reconstruction matrix combined with different levels of Karl algorithm to obtain four subgroups,including B1(Karl 6),B2(Karl 7),B3(Karl 8)and B4(Karl 9)subgroup.The signal-to-noise ratio was calculated by measuring the CT and standard deviation values of the tracheal lumen above the arch of the aorta(tracheal area)and the avascular area of the upper lobe of the left lung(lung parenchyma).The overall image quality of the lungs in group A and B was evaluated by two physicians.The best image quality subgroup in group B was compared with the lesion display in group A.The diagnostic efficacy was analyzed based on the surgical pathology results.Results In group B,the standard deviation values of trachea and lung parenchyma gradually decreased and the signal-to-noise ratio gradually increased as the Karl grade increased compared with group A(F=675.002-2 020.903,all P<0.05).All subjective scores in group B were significantly higher than those in group A(Z=-15.361--6.465,all P<0.05),and the highest subjective scores were found in group B4.Some solid nodules(≤3 mm)and solid nodules(6.1 mm-≤3 cm)showed no statistically significant difference in clarity(Z=-2.000,-0.378,both P>0.05).Compared with group A,group B4 showed a 12%-100%improvement in nodule clarity.Only pleural depression sign showed the difference was not statistically significant(χ2=2.143,P>0.05).Taking 43 cases of surgical pathology as the gold standard,the diagnostic accuracy of group B4 was 65.12%,which was better than that of group A,which was 41.86%(χ2=4.674,P<0.05).Conclusion The combined application of the large reconstruction matrix and the Karl iteration algorithm results in superior image quality and facilitates the diagnosis of lung nodules.

Objective To evaluate the risk of bias and reporting quality in randomized controlled trials(RCTs)of the Chinese medicine injection for acute cerebral infarction in the last five years.Methods RCTs literature on Chinese medicine injection in the treatment of acute cerebral infarction was systematically searched in CNKI,Wanfang Data,VIP,China Biology Medicine Database(CBM),PubMed,Embase and Cochrane Library from April 20,2018 to April 20,2023.The risk of bias and reporting quality of included RCTs were evaluated using the Cochrane Risk of Bias Tool(ROB 1.0)and CONSORT-CHM Formulas 2017,respectively.Results A total of 4 301 articles were retrieved,and 408 RCTs were included according to inclusion and exclusion criteria.The ROB evaluation results showed that the the majority of studies were rated as having an unclear risk of bias due to the lack of reporting on allocation concealment,blind method,trial registration information,and funding sources.The evaluation results of CONSORT-CHM Formulas 2017 showed that the number of reported papers of 17 items was greater than or equal to 50%,and the number of reported papers of 25 items was less than 10%,and most of the RCTs did not show the characteristics of TCM syndrome differentiation and treatment.Conclusion The quality of Chinese medicine injection in the treatment of acute cerebral infarction RCTs is generally low.It is recommended that researchers refer to the methodology design of RCTs and international reporting standards,improve the trial design,standardize the trial report,and highlight the characteristics of TCM syndrome differentiation and treatment.

Objective:To explore the correlation between transcranial sonography (TCS) combined with serum homocysteine (Hcy), blood glucose, blood lipids, the cognitive status of Parkinson′s disease (PD) patients, and to analyze the clinical application value of these parameters in assessing the cognitive status of PD patients.Methods:A total of 152 PD patients admitted to the Second Affiliated Hospital of Soochow University from January 2020 to June 2023 were retrospectively collected as the PD group, and 101 healthy examinees matched for age and gender during the same period were selected as control group. Clinical data [age, gender, duration of illness, Montreal Cognitive Assessment (MoCA) score, Mini-Mental State Examination (MMSE) score, Unified Parkinson′s Disease Rating Scale Part Ⅲ (UPDRS-Ⅲ) score, Hoehn-Yahr (H-Y) stage, etc.], serum tests (Hcy, blood glucose, total cholesterol, triglycerides, low-density lipoprotein, high-density lipoprotein concentration), and TCS examination results (third ventricular width, midbrain area, peak systolic velocity of bilateral middle cerebral arteries, bilateral middle cerebral artery resistance index, bilateral substantia nigra hyperechoic area) were collected. The two groups were divided into pure PD group and PD group with elevated Hcy, pure control group and control group with elevated Hcy, based on an Hcy concentration threshold of ≥15 μmol/L. The differences in the above parameters among the four groups were compared. The correlation between Hcy and cognitive status (MoCA score, MMSE score) of PD patients and the above parameters were analyzed.Results:The MoCA score and MMSE score of the PD group with elevated Hcy were lower than those of the pure PD group, and the UPDRS-Ⅲ score and H-Y stage were higher than those of the pure PD group (all P<0.001). The order of Hcy concentration from high to low was PD group with elevated Hcy, pure Hcy elevation group, pure PD group, and pure control group. The differences in serum data and TCS data among the four groups were statistically significant (all P<0.001). Spearman correlation analysis showed: ①In the PD group, the concentration of Hcy was positively correlated with glucose concentration, H-Y stage, low-density lipoprotein concentration, right middle cerebral artery resistance index, UPDRS-Ⅲ score, total cholesterol concentration, triglyceride concentration, left middle cerebral artery resistance index, third ventricular width, and age ( rs=0.422, 0.350, 0.348, 0.334, 0.325, 0.300, 0.293, 0.283, 0.221, 0.164, all P<0.05); Hcy concentration was negatively correlated with midbrain area, MMSE score, MoCA score, peak systolic velocity of right middle cerebral artery, peak systolic velocity of left middle cerebral artery, and high-density lipoprotein concentration ( rs=-0.328, -0.282, -0.245, -0.229, -0.224, -0.192, all P<0.05). ②Clinical data, serum data, and TCS data of PD patients were all correlated with MoCA score and MMSE score, with midbrain area showing the largest positive correlation ( rs=0.524, 0.516; both P<0.05) and H-Y stage showing the largest negative correlation( rs=-0.490, -0.468; both P<0.05). Conclusions:PD patients with elevated Hcy have lower cognitive scores than pure PD patients. The correlation between Hcy concentration and blood glucose concentration is the highest in PD patients, followed by H-Y stage. The cognitive scores of PD patients are most correlated with midbrain area and unrelated to substantia nigra hyperechoic area. Lowering serum Hcy concentration in PD patients may be one of the ways to delay cognitive impairment.

Purpose To analyze the expression of FOXA3 in colorectal cancer(CRC)and its correlation with clinicopatho-logical features.Methods FOXA3 mRNA expression in 31 CRC cancer tissues and their matched normal tissues was detec-ted by real-time quantitative PCR(RT-qPCR).The protein ex-pression of FOXA3 in 120 CRC cancer tissues was detected by immunohistochemical EnVision two-step method,and the clini-copathologic features such as lymph node metastasis and immu-nohistochemical expression were analyzed.Results The mRNA expression level of FOXA3 in colorectal cancer tissues was sig-nificantly higher than that in paired paracancer tissues(t=2.952,P=0.006 1).FOXA3 protein expression level in color-ectal cancer tissues was not significantly correlated with gender,age,site and size of patients,but significantly correlated with the degree of tissue differentiation(P=0.006)and lymph node metastasis(P=0.002).The degree of differentiation was nega-tively correlated with FOXA3 expression,while lymph node me-tastasis was positively correlated with FOXA3 expression.Sur-vival analysis showed that higher FOXA3 expression was associ-ated with worse overall survival(P＜0.000 1),and FOXA3 was an independent risk factor for prognosis in patients with colorectal cancer.Conclusion This study suggests that FOXA3 may play a promoting role in the occurrence and development of colorectal cancer,and FOXA3 may be a molecular marker for the diagnosis,metastasis and prognosis of colorectal cancer.
