OBJECTIVE To explore the clinical efficacy of clarithromycin sustained-release tablets in the primary eradication of Helicobacter pylori. METHODS Retrospective analysis of the data of patients with primary eradication of Helicobacter pylori admitted to the outpatient department of Tongde Hospital of Zhejiang Province from January 2019 to December 2020 was conducted. They were divided into three groups according to the choice of clarithromycin dosage form and dosage, namely, clarithromycin tablets 500 mg bid treatment group(group A), clarithromycin sustained-release tablets 500 mg bid treatment group(group B), and clarithromycin sustained-release tablets 500 mg qd treatment group(group C). At least 4 weeks after the end of treatment in each group, telephone follow-up was conducted to compare and analyze the efficacy, compliance, recurrence rate, incidence of adverse reactions, and cost effectiveness ratio of different treatment schemes for eradication. RESULTS After eliminating lost visits, a total of 350 cases were included in this study, including 132 cases in group A, 101 cases in group B, and 117 cases in group C. The overall eradication rates in each group were 95.45%, 92.08%, and 97.44%, respectively. Six patients with low compliance were excluded (3 in group A, 3 in group B, and 0 in group C), with eradication rates of 95.35%, 92.86%, and 97.44%, respectively. There was no significant difference in the eradication rate, compliance, recurrence rate, and incidence of adverse reactions among the groups, but the cost effectiveness ratio in group C was the lowest. Taking group A as a reference, the incremental cost effectiveness ratio for group C was ‒156.459. CONCLUSION Clarithromycin sustained-release tablets can be safely and effectively used in the primary eradication treatment of patients with Helicobacter pylori infection, and can be used according to the recommended dosage in the instructions.

Objective To explore the effectiveness of clinical pharmacists participating in anti-infection treatment for severe infection patients in the intensive care unit.Methods A retrospective collection of severe infection patients admitted to the ICU of the Fourth People's Hospital of Jinan from January to June 2023 was conducted through the hospital information system.Among them,some patients with clinical pharmacists participating in anti-infection treatment throughout the process were in the intervention group,and other patients who did not participate in treatment were in the control group.Both groups of patients received routine treatment according to clinical diagnosis.We compared the cure rate,incidence of adverse reactions,cost of antibiotics,proportion of antibiotic costs,pathogen testing rate,duration of antibiotic treatment,and average length of hospital stay between two groups of patients,and conducted statistical analysis.Results A total of 147 patients were included,with 66 in the intervention group and 81 in the control group.The cure rate of patients in the intervention group was 65.15％,significantly higher than 46.91％in the control group(P＜0.05);The incidence of adverse reactions(7.58％)was significantly lower than that of the control group(19.75％)(P＜0.05).The usage rates of quinolone drugs and tigecycline were significantly reduced in the intervention group;The intervention group had significantly better indicators such as antibiotic costs,proportion of antibiotic costs,and patient pathogen testing rate than the control group(P＜0.05).There were no significant difference in the duration of antimicrobial treatment and average length of hospital stay between the two groups(P＞0.05).Conclusion The full participation of clinical pharmacists in the anti-infection treatment of ICU severe infection patients can help improve their clinical cure rate and medication safety,and reduce their medical burden.

Objective To investigate and analyze the epidemiological characteristics of nosocomial infection in the neurosurgery department of Jinan Fourth People's Hospital,and to provide reference for nosocomial infection prevention and control and rational use of antibiotics.Methods The infection related information of 5 200 inpatients in neurosurgery from January 2019 to December 2022 was retrospectively collected through the hospital infection monitoring system and hospital information system,and the distribution of infection sites,the incidence of hospital infection,distribution of pathogens and drug resistance were statistically and descriptively analyzed.Results From 2019 to 2022,the average infection rate of inpatients in the neurosurgery department was 3.3%,which was decreased year by year(χ2=39.000,P<0.001).Nococomial infections mostly occurred in elderly male patients,the infection sites were mainly lower respiratory tract,urinary system,bacteremia,and intracranial infection.From 2019 to 2022,296 strains of pathogenic bacterium were detected in neurosurgery,including 207 strains of Gram-negative bacteria,accounting for 69.9%;53 Gram-positive bacterium,accounting for 17.9%;36 Fungi,accounting for 12.2%.The top four pathogens were Klebsiella pneumoniae(21.6%),Pseudomonas aeruginosa(12.5%),Escherichia coli(9.8%),and Acinetobacter baumannii(8.8%).The drug sensitivity results showed that the resistance of Acinetobacter baumannii to carbapenems was significant.Conclusion In the past four years,the incidence of nosocomial infections of the Neurosurgery department has improved year by year.The pathogenic bacteria detected were mainly gram-negative bacteria,and the problem of drug resistance is more prominent.The drug resistance management should be strengthened.

In recent years, immunotherapy with immune checkpoint as the target has made revolutionary breakthroughs in the treatment of a variety of advanced solid tumors. Notwithstanding the impressive long-term therapeutic benefits, their efficacy is limited to a small subset of cancer patients. Some patients experienced drug resistance and immune-related adverse events (irAEs). Immune checkpoint inhibitors (ICIs) primarily include antibodies targeting CTLA-4 and antibodies targeting PD-1 and its ligands. Thus, it is of utmost importance to screen potential biomarkers in populations that may benefit from immunotherapy, to maximize therapeutic benefits. This review summarizes the mechanism of ICIs and its related efficacy biomarker, to better guide the application of immunotherapy in clinical practice.

Objectives:To explore the prognostic factors of primary central nervous system lymphoma(PCNSL) and to analyze the efficacy of different treatment methods.Methods:Clinical data of 4 812 patients with PCNSL in SEER database from January 1975 to December 2016 were retrospectively analyzed.Among them, 2 831 were male and 1 981 were female, the ratio of male to female was 1.4∶1.0.There were 2 236 cases(46.47%) under 60 years old, 1 718 cases(35.70%) aged 60 to 74 years old, and 858 cases(17.83%) aged 75 years old or above. Two thousand four hundred and seventeen cases(50.23%) had supratentorial tumors, 299 cases (6.21%) had infratentorial tumors, and 554 cases(11.51%) had multiple brain tumors, 1 542 cases (32.04%) were other or unspecified location.Three thousand five hundred and thirteen cases(73.00%) had diffuse large B-cell lymphoma (DLBCL), 234 cases(4.86%) had non DLBCL, 1 065 cases (22.13%) had other or unspecified types of tumor.The treatment included 2 011 cases (41.77%) of biopsy, 61 cases (1.27%) of subtotal resection(STR), 54 cases (1.12%) of gross total resection(GTR), 2 384 cases (49.54%) of biopsy and chemotherapy, 159 cases (3.30%) of STR and chemotherapy, 144 cases (3.00%) of GTR and chemotherapy.Univariate and multivariate Cox regression models were used to analyze the prognostic factors affecting the overall survival of the patients.Fine-Gray test and competitive risk model were used to analyze the prognostic factors affecting cancer-specific survival.Kaplan-Meier method and Log-rank test was used for survival analysis.Results:Univariate and multivariate Cox regression analyses showed that age, race, marital status, tumor site, pathological subtype, surgery, chemotherapy, combined with other malignant tumors, and HIV infection were the independent prognostic factors affecting the overall survival of PCNSL patients.The results of Fine-Gray test and competitive risk model analyses showed that age, race, marital status, tumor location, pathological subtype, surgical method, chemotherapy, combined with other malignant tumors, and HIV infection were independent prognostic factors affecting cancer-specific survival, while gender and radiotherapy had no significant correlation with cancer-specific survival.Compared with biopsy, PCNSL patients may benefit from surgical resection (STR: HR=0.805, 95% CI:0.656?0.989, P=0.04; GTR: HR=0.521, 95% CI:0.414?0.656, P<0.01).Kaplan-Meier survival analysis showed that the median survival time of biopsy+chemotherapy group was 28 months (95% CI:24.497?31.503), 2 months (95% CI:1.756?2.244) in the biopsy group, 2 months (95% CI:1.410-2.590) in the STR group, 19 months ( 95%CI:0?39.311) in the biopsy+chemotherapy group, 67 months (95% CI:46.187-87.813) in the STR+chemotherapy group, 84 months (95% CI:57.448?110.552) in the GTR+chemotherapy group.The median survival time of patients with different treatment methods was statistically significant ( P<0.01). Conclusions:Surgical resection may improve the prognosis of some PCNSL patients.Patients who have access to receive GTR or STR combined with chemotherapy may have prolonged Cancer-specific survival.

Objective To learn about the current situation and trends of novel coronavirus diseases 2019 (COVID-2019) in foreign countries. Methods The data on confirmed COVID-2019 cases were collected between January 20, 2020 and February 18, 2020 and by age, sex, nationality, contact history, region, and country were performed stratified analysis and onset time analysis. Results From January 20th to February 18th, the cumulative number of confirmed cases of COVI D-2019 abroad was 804. Excluding the 454 cases on the 'Diamond Princess' cruise ship in Japan, the daily number of new cases fluctuated, showed a trend of rising first and then maintaining a steady trend. The peak date for new cases was on February 1, with the number of cases reaching 26. The confirmed cases were mainly concentrated in Asian countries, but also distributed in Europe, North America, Oceania and Africa. As of February 15, there was no more increase reported in the number of countries where confirmed cases occurred after reaching 25. Among these countries, Singapore, Japan, and Thailand were with the highest number of cases, with 77, 65, and 35 cases, respectively. In accordamce to available information on confirmed cases, the cases with history of exposure to confirmed cases were more than those with history of living or traveling in Hubei. And more cases were non-Chinese nationalities, 40 years old and above, and males . Conclusion The novel coronavirus has transmitted abroad, and produced second-generation cases. Although the incidence is low abroad , its trend fluctuates greatly, so sufficient attention must be paid to the possibility of further transmission.

Objective:To evaluate the association of abdominal obesity and obesity types with carotid intima-media thickness (cIMT) in children and provide scientific evidence for the prevention of abnormal vascular structure.Methods:Based on the "Children’s Cardiovascular Health Cohort" conducted in Huantai county of Zibo, Shandong province from November 2017 to January 2018, a total of 1 240 children, including 657 boys (53.0%), who had completed data of sex, age, physical examinations, blood biochemical indices and lifestyle variables (collected by questionnaires) were included for the analysis. Covariance analysis was used to compare the levels of cIMT in groups with normal waist circumference, pre-abdominal obesity and abdominal obesity. Logistic regression analysis was used to evaluate the association of pre-abdominal obesity and abdominal obesity with high cIMT, and the association of combined effect of general overweight or obesity and abdominal obesity or pre-abdominal obesity with high cIMT.Results:The levels of cIMT in children with pre-abdominal obesity (0.47±0.03) mm and abdominal obesity (0.50±0.04) mm were higher than that in children with normal waist circumference (0.45±0.05) mm, the difference was significant ( P<0.001). The detection rates of high cIMT in children with pre-abdominal obesity(20.8%) and abdominal obesity (49.5%) were higher than that in children with normal waist circumference (8.8%), the difference was significant ( P<0.001). Compared with normal waist circumference, pre-abdominal obesity and abdominal obesity were significantly associated with high cIMT (pre-abdominal obesity: OR=2.53, 95 %CI: 1.67-3.84; abdominal obesity: OR=8.56, 95 %CI: 5.97-12.29) after adjustment for potential covariates. Compared with normal body mass index and normal waist circumference, abdominal obesity or pre-abdominal obesity alone ( OR=2.24, 95 %CI: 1.36-3.69), and mixed overweight and obesity ( OR=6.94, 95 %CI: 4.87-9.90) were significantly associated with high cIMT. Conclusions:The association between abdominal obesity and high cIMT was significant in children, and the association was stronger between mixed overweight or obesity and high cIMT, suggesting that we should consider mixed overweight and obesity in the prevention of abnormal vascular structure.

Objective:To analyze the trends in blood pressure (BP) values and the elevated BP based on the measurements at three occasions in different days and its relationship with obesity in children and provide scientific evidence for the identification and prevention of hypertension in children.Methods:A public primary school in Huantai county of Zibo, Shandong province, was selected as the investigation field by using a convenient cluster sampling method. The baseline survey of "Children’s Cardiovascular Health Cohort" was carried out from November 2017 to January 2018. All the students with willingness and informed consent in this school were included in the survey, and the valid sample size was 1 505 children (aged 6-11 years). Children with elevated BP at the measurement of the first occasion should had a second measurement 2 weeks later, and a third measurement was given 2 weeks later if BP was still high at the measurement of the second occasion. Hypertension was confirmed if elevated BP was detected in the measurements at all the three occasions in different days. Multivariate linear regression model was used to assess the trend in BP values in children in the measurements at three occasions in different days, Cochran-Armitage trend analysis was used to evaluate the trend of elevated BP, and logistic regression model was used to analyze the relationship of elevated BP with obesity at three occasions in different days.Results:In this study, with the increase of follow-up visits, the BP levels continued to rise (trend P<0.05). The elevated BP rates at three occasions were 15.5%, 4.0% and 1.9%, respectively, showing a significantly downward trend (trend P<0.05). Compared with both normal weight and normal waist circumference, the association between obesity types (general obesity only, abdominal obesity only, and mixed obesity) and elevated BP at three occasions increased (the first occasion: OR=3.62, 95 %CI: 2.65-4.96; the second occasion: OR=9.50, 95 %CI: 4.95-18.22; and the third occasion: OR=8.94, 95 %CI: 3.48-22.96; all P<0.05). Stratified analysis by gender showed similar results. Conclusions:The elevated BP rates based on the measurements at three occasions in different days in children aged 6-11 years showed a significant decrease trend. The association between different types of obesity (especially mixed obesity) and elevated BP in children became stronger gradually with the progress of the follow up.

Objective To investigate the relationship between serum 25-hydroxyvitamin D [25(OH)D] level and the risk of metabolic syndrome ( MS) and its components in patients with type 2 diabetes mellitus. Methods Clinical data of 796 type 2 diabetic inpatients in the Department of Endocrinology, the Ninth People' s Hospital, Shanghai Jiaotong University School of Medicine, from January 2017 to December 2018 were enrolled. These patients were divided into MS group (n=541) and non-MS group (n=255). The association of serum vitamin D level and metabolic syndrome was investigated. Results The level of 25( OH) D in MS group was significantly lower than that in non-MS group (P<0.05). According to 25(OH)D 20 ng/ml as the borderline of vitamin D deficiency, the rate of 25(OH)D deficiency in MS group was significantly higher than that in non-MS group (P<0.01). Serum 25(OH)D levels in patients with type 2 diabetes were negatively correlated with smoking, body mass index, systolic blood pressure, diastolic blood pressure, waist circumference, triglyceride, and low density lipoprotein-cholesterol levels ( all P<0.05) . Multiple logistic regression analysis showed that 25( OH) D was an independent protective factor for MS in patients with type 2 diabetes. These patients were divided into 4 subgroups according to 25( OH) D levels [ Q1:0-10 ng/ml (n=24), Q2:10-20 ng/ml (n=417), Q3:20-30 ng/ml (n=117), Q4≥30 ng/ml(n=18)]. Logistic regression showed that the risk ratios (OR) of the metabolic syndrome in the Q2, Q3, and Q4 groups were 0.471, 0.389, and 0.211 respectively, compared with Q1 group (P<0.05).Conclusion Serum 25(OH)D level in type 2 diabetic patients was negatively correlated with the risk of MS.
