Objective To investigate prevalence and immunological properties of Helicobacter pylori (Hp) infection among chronic gastritis population in Wuhan. Methods A total of 1 866 patients with chronic gastritis in Wuhan were selected from May 2021 to December 2023, and Hp antibody and typing in serum were detected by immunoblotting to analyse the infection rate and typing of patients of different genders and age groups, as well as the correlation between Hp infection and the severity of chronic gastritis. Western blotting technique was utilized to detect the Hp antibodies and typing. The infection rates and subtypes were recorded in patients of different genders and ages. Then the correlation between Hp infection and the severity of chronic gastritis were discussed. Results The overall detection rate of Hp infection was 65.38% (1 220/1 866) in 1866 patients, and the prevalence rate of type I infection was higher than that of type II infection [61.31% (748/1 220) vs 38.69% (472/1 220), P<0.05]. No statistical difference was reported in overall infection rate in terms of gender (P>0.05). In terms of gender, the rate of type I infection was higher than that of type II infection [70.08% (431/615) vs 29.92% (184/615), P<0.05], whereas the prevalence of the two types of infections demonstrated no statistical difference in female patients (P>0.05). In terms of age, the prevalence of Hp infection in patients increased with age (2=64.687, P=0.000). The infection rate of type I was higher than type II in the age groups of below 18, 31-40, 41-50 and 51-60 years old (P<0.05), and infection rates of type I and type II yielded no statistical difference in the age groups of 18-30 and ≥60 years old (P>0.05). With the aggravation of chronic gastritis, the infection rate and percentage of type I infections increased, and the percentage of type I infections was higher than that of type II infections (P<0.05). Conclusion Patients with chronic gastritis in Wuhan suffer a high prevalence rate of Hp infection, and the rate of Hp infection increases with the age of the patients, is positively correlated with the severity of the disease, and presents certain typological features.

ObjectiveTo investigate the effects and mechanism of Zuogui Jiangtang Tongmai prescription （ZJTP） on human umbilical vein endothelial cells （HUVECs） damaged by high glucose combined with lipopolysaccharide （LPS）. MethodThe survival rate of cells was determined by cell counting kit-8 （CCK-8）， and the level of tumor necrosis factor-α （TNF-α） was determined by enzyme-linked immunosorbent assay （ELISA） to determine the optimal injury concentration and action time of LPS， as well as the optimal action concentration of ZJTP drug-containing serum. HUVECs were divided into a blank control group， a model group， a ZJTP drug-containing serum group， and an SCFA mixed liquid group. ELISA was used to detect the level of endothelin-1 （ET-1）， nitric oxide （NO）， interleukin-1β （IL-1β）， interleukin-6 （IL-6）， and TNF-α. Western blot was performed to detect the protein expression of G protein-coupled receptor43 （GPR43）， β-suppressor protein-2 （β-arrestin-2）， nuclear factor-κB suppressor α （IκBα）， and nuclear factor κB p65 （NF-κB p65）. The nucleation of NF-κB p65 was observed by immunofluorescence staining （IF）. The role of GPR43 in the regulation of inflammatory injury was observed by means of small interfering ribonucleic acid （siRNA）. The cells after intervention were divided into an empty carrier group， a ZJTP drug-containing serum group， a Si-GPR43 group， and a Si-GPR43 + ZJTP drug-containing serum group. The content of IL-1β， IL-6， and TNF-α was detected by ELISA. The protein expression of pathways was detected by Western blot. IF was used to observe the nucleation of NF-κB p65. ResultThe optimal molding condition was 1 mg·L^-1 LPS for 24 h. The optimal drug intervention condition was 5% ZJTP drug-containing serum for 24 h. Compared with the blank control group， the content of ET-1 in the model group was significantly increased， and the content of NO was significantly decreased （P<0.01）. The levels of inflammatory factors were significantly increased （P<0.01）. The expressions of GPR43 and IκBα were significantly decreased， while the protein expressions of β-arrestin-2 and NF-κB p65 were significantly increased （P<0.01）. NF-κB p65 protein was transferred from the extranuclear to the intranuclear （P<0.01）. Compared with the model group， the content of ET-1 in the ZJTP drug-containing serum group was decreased， and the content of NO was increased （P<0.05）. The levels of inflammatory factors decreased （P<0.05）. The protein expressions of GPR43 and IκBα were increased， while the expressions of β-arrestin-2 and NF-κB p65 were decreased （P<0.05）. The amount of NF-κB p65 transferred from the intranuclear to the extranuclear decreased （P<0.01）. The mechanism study showed that compared with the Si-GPR43 group， the content of IL-1β， IL-6， and TNF-α were significantly decreased after treatment with ZJTP drug-containing serum （P<0.01）. The protein expressions of GPR43 and IκBα were significantly increased （P<0.01）， while the protein expressions of β-arrestin-2 and NF-κB p65 were significantly decreased （P<0.01）. The amount of NF-κB p65 transferred from the extranuclear to the intranuclear decreased （P<0.01）. ConclusionZJTP has a protective effect on HUVECs with high glucose and LPS-induced inflammatory injury， which may be related to the regulation of GPR43/β-arrestin-2/IκBα/NF-κB pathway.

Objective To investigate the expression level and clinical significance of serum long noncoding RNA(lncRNA)H19,CHAST in patients with coronary heart disease(CHD).Methods A total of 135 patients with CHD who were admitted to the Department of Cardiovascular Medicine of Lianyungang Second People's Hospital from June 2021 to May 2022 were selected,including 76 cases of a-cute coronary syndrome and 59 cases of chronic coronary syndrome.We selected 62 patients in the control group who were hospitalized and excluded from CHD by coronary angiography.Real-time fluorescent quantitative PCR(RT-PCR)was used to detect the relative expres-sion level of lncRNA H19 and lncRNA CHAST in the circulating serum of the subjects.Meanwhile,the high sensitivity C-reactive pro-tein(hs-CRP)、tumor necrosis factor-α(TNF-α)、interleukin-6(IL-6)、low density lipoprotein(LDL)、high density lipoprotein(HDL)and other related indicators of each group were collected.The receiver operating characteristic(ROC)curve was used to analyze the clinical diagnostic value of circulating serum lncRNA H19 and lncRNA CHAST expression level in the diagnosis of CHD.Pearson cor-relation coefficient was used to analyze the correlation between serum lncRNA H19,lncRNA CHAST level,and other related indicators.Multivariate Logistic regression was used to analyze the risk factors of CHD.Results The serum expression levels of lncRNA H19 and ln-cRNA CHAST in the CHD group were higher than those in the control group(P＜0.05).The serum levels of hs-CRP、TNF-α、IL-6、and LDL in the experimental group were higher than those in the control group(P＜0.05),and the serum levels of HDL were lower than those in the control group(P＜0.05).The expression levels of lncRNA H19 and lncRNA CHAST were positively correlated with hs-CRP,IL-6 and LDL,and were negatively correlated with HDL.lncRNA H19 and lncRNA CHAST are risk factors for CHD,which may have a higher value in the diagnosis of CHD.Conclusion lncRNA H19 and lncRNA CHAST are risk factors for CHD and can be used as serum indicators for the diagnosis of CHD,and the combination of the two has a higher value in the diagnosis of CHD.In addition,the ex-pression levels of both were correlated with the levels of inflammatory factors and apolipoproteins.

OBJECTIVE To observe the short-term efficacy and safety of venetoclax combined with homoharringtonine and cytarabine in the treatment of acute myeloid leukemia （AML）. METHODS The data of 40 newly diagnosed AML patients admitted to our hospital from October 2022 to November 2023 were retrospectively collected and divided into observation group and control group according to treatment plan， with 20 cases in each group. The patients in the control group were given Daunorubicin hydrochloride for injection+Cytarabine for injection， and the patients in the observation group were given Venetoclax tablets+ Homoharringtonine injection+Cytarabine for injection. The patients in both groups were given relevant medicine， with 28 days as one cycle. The short-term efficacy， negative rate of minimal residual disease （MRD）， duration of granulocyte deficiency， duration of platelet （PLT） ＜20×109 L－1， transfusion volume of suspended red blood cells and platelet， and the occurrence of adverse drug reactions were evaluated in both groups after 1 cycle of induction chemotherapy. RESULTS The complete remission or complete remission with incomplete hematologic recovery （CR/CRi） rate in the observation group was significantly higher than control group （P＜0.05）， and the negative rate of MRD in the observation group was also significantly higher than control group （P＜0.05）. However， in low-， medium- and high-risk patients， there was no statistical significance in CR/CRi rates between the two groups （P＞0.05）. There were no significant differences in the duration of agranulocytosis， the duration of PLT ＜20×109 L－1， the amount of suspended red blood cell transfusion， the amount of platelet transfusion， the incidence of hematologic toxicity and the incidence of non-hematologic toxicity between 2 groups （P＞0.05）. CONCLUSIONS Venetoclax combined with homoharringtonine and cytarabine show good short-term efficacy and safety in the treatment of AML.

Objective This paper investigates the effect of a multi-physical field fusion intervention based on transcranial direct current stimulation(tDCS),transcranial magnetic stimulation(TMS)and music on mental fatigue.Methods After fatigue induction,10 subjects received blank group stimulation,music group stimulation and tDCS-TMS-Music stimulation,respectively.tDCS stimulation sites were located in the bilateral frontal regions of the subjects,and TMS stimulation sites were located in the bilateral occipital regions of the hindbrain.Heart rate variability and reaction performance were measured before and after each intervention to determine the elimination effect of different intervention programs on mental fatigue.Results Compared with the control group,the tDCS-TMS-Music group showed significantly greater improvements in subjective mental workload,response performance,and heart rate variability.Conclusion The results of this study support that tDCS-TMS-Music can effectively alleviate mental fatigue induced by long-term cognitive performance tasks,and the intervention effect is better than music intervention and resting-state relief at the same time.

Objective:To explore the effects of short-term particulate matter(PM)exposure and the melatonin receptor 1B(MTNR1B)gene on triglyceride-glucose(TyG)index utilizing data from Fang-shan Family-based Ischemic Stroke Study in China(FISSIC).Methods:Probands and their relatives from 9 rural areas in Fangshan District,Beijing,were included in the study.PM data were obtained from fixed monitoring stations of the National Air Pollution Monitoring System.TyG index was calculated by fasting triglyceride and glucose concentrations.The associations of short-term PM exposure and rs10830963 polymorphism of the MTNR1B gene with the TyG index were assessed using mixed linear models,in which covariates such as age,sex,and lifestyles were adjusted for.Gene-environment inter-action analysis was furtherly performed using the maximum likelihood methods to explore the potential effect modifier role of rs10830963 polymorphism in the association of PM with TyG index.Results:A total of 4 395 participants from 2 084 families were included in the study,and the mean age of the study participants was(58.98±8.68)years,with 53.90％females.The results of association analyses showed that for every 10 μg/m3 increase in PM2.5 concentration,TyG index increased by 0.017(95％CI:0.007-0.027),while for per 10 μg/m3 increment in PM1o,TyG index increased by 0.010(95％CI:0.003-0.017).And the associations all had lagged effects.In addition,there was a positive association between the rs10830963 polymorphism and the TyG index.For per increase in risk allele G,TyG index was elevated by 0.040(95％CI:0.004-0.076).The TyG index was 0.079(95％CI:0.005-0.152)higher in carriers of the GG genotype compared with carriers of the CC genotype.The inter-action of rs10830963 polymorphism with PM exposure had not been found to be statistically significant in the present study.Conclusion:Short-term exposure to PM2.5 and PM10 were associated with higher TyG index.The G allele of rs10830963 polymorphism in the MTNR1B gene was associated with the elevated TyG index.

Objective:To evaluate the health benefits and intervention efficiency of different strategies of initiating antihypertensive therapy for the primary prevention of cardiovascular diseases in a community-based Chinese population from the Chinese electronic health records research in Yinzhou(CHERRY)study.Methods:A decision-analytic Markov model was used to simulate and compare different antihy-pertensive initiation strategies,including:Strategy 1,initiation of antihypertensive therapy for Chinese adults with systolic blood pressure(SBP)≥140 mmHg(2020 Chinese guideline on the primary preven-tion of cardiovascular diseases);Strategy 2,initiation of antihypertensive therapy for Chinese adults with SBP≥130 mmHg;Strategy 3,initiation of antihypertensive therapy for Chinese adults with SBP ≥140 mmHg,or with SBP between 130 and 140 mmHg and at high risk of cardiovascular diseases(2017 American College of Cardiology/American Heart Association guideline for the prevention,detection,evaluation,and management of high blood pressure in adults);Strategy 4,initiation of antihypertensive therapy for Chinese adults with SBP≥ 160 mmHg,or with SBP between 140 and 160 mmHg and at high risk of car-diovascular diseases(2019 United Kingdom National Institute for Health and Care Excellence guideline for the hypertension in adults:Diagnosis and management).The high 10-year cardiovascular risk was de-fined as the predicted risk over 10％based on the 2019 World Health Organization cardiovascular disease risk charts.Different strategies were simulated by the Markov model for ten years(cycles),with parame-ters mainly from the CHERRY study or published literature.After ten cycles of simulation,the numbers of quality-adjusted life years(QALY),cardiovascular events and all-cause deaths were calculated to evaluate the health benefits of each strategy,and the numbers needed to treat(NNT)for each cardiovas-cular event or all-cause death could be prevented were calculated to assess the intervention efficiency.One-way sensitivity analysis on the uncertainty of incidence rates of cardiovascular disease and probabilis-tic sensitivity analysis on the uncertainty of hazard ratios of interventions were conducted.Results:A to-tal of 213 987 Chinese adults aged 35-79 years without cardiovascular diseases were included.Com-pared with strategy 1,the number of cardiovascular events that could be prevented in strategy 2 increased by 666(95％UI:334-975),while the NNT per cardiovascular event prevented increased by 10(95％UI:7-20).In contrast to strategy 1,the number of cardiovascular events that could be prevented in strategy 3 increased by 388(95％UI:194-569),and the NNT per cardiovascular event prevented decreased by 6(95％UI:4-12),suggesting that strategy 3 had better health benefits and intervention efficiency.Compared to strategy 1,although the number of cardiovascular events that could be prevented decreased by 193(95％UI:98-281)in strategy 4,the NNT per cardiovascular event prevented decreased by 18(95％UI:13-37)with better efficiency.The results were consistent in the sensitivity analyses.Conclusion:When initiating antihypertensive therapy in an economically developed area of China,the strategy combined with cardiovascular risk assessment is more efficient than those purely based on the SBP threshold.The cardiovascular risk assessment strategy with different SBP thresholds is suggested to balance health benefits and intervention efficiency in diverse populations.

Objective To investigate the prognostic evaluation value of the HALP score composed of hemoglobin,albumin,lymphocytes and platelets before chemotherapy in the patients with diffuse large B-cell lymphoma(DLBCL).Methods The clinical data and laboratory indicators before chemotherapy in the pa-tients with DLBCL newly diagnosed in this hospital from January 2015 to October 2022 were retrospectively analyzed.The optimal cut-off value of HALP was calculated by X-tile software.The patients were grouped ac-cording to the optimal cutoff value,the Chi-square test was used to analyze the difference in the constituent ra-tio of clinical characteristics among different HALP score groups,the survival curves of the progression-free survival(PFS)time and overall survival(OS)time among the groups with different scores were drawn by u-sing the Kaplan-Meier method,the Cox univariate and multivariate analysis regression model was adopted to analyze the prognostic influencing factors in DLBCL patients,and the predictive ability of HALP score for PFS time and OS time in DLBCL patients was evaluated by using the receiver operating characteristic(ROC)curve.Results A total of 132 patients with DLBCL were included,the optimal cutoff value of HALP score was 21.23 points.There were 54 cases in the low HALP score group and 78 cases in the high HALP score group.The low HALP score group was correlated with the later clinical stage,higher IPI and NCCN-IPI scores,higher LDH level and lower overall response rate(ORR)(P＜0.05).Compared to the high HALP score group,the PFS time and OS time in the low HALP score group were shorter(P＜0.05).The Cox uni-variate and multivariate regression model analysis results indicated that the HALP score≤21.23 points was an independent risk factor affecting the PFS time(HR=1.811,P=0.031).The ROC curve results suggested that the combination of HALP score combined with IPI score or NCCN-IPI score had higher predictive value for PFS time and OS time in DLBCL patients compared to use IPI or NCCN-IPI alone.Conclusion The HALP score is correlated with the prognosis of DLBCL patients,and could early identify the high-risk DLBCL patients with poor prognosis.The HALP score,IPI score and NCCN-IPI score combined evaluation has higher predictive value.

Objective To explore the correlation between eosinophils(EOS),interleukin-17A(IL-17A),tumor necrosis factor α(TNF-α)and vascular endothelial growth factor(VEGF)in peripheral blood and my-coplasma pneumoniae infection with wheezing in children.Methods A total of 98 children with mycoplasma pneumoniae infection diagnosed and treated in the hospital from January 2022 to May 2023 were selected as the study group.The study group was divided into wheezing group(32 cases)and non-wheezing group(66 ca-ses)according to whether they were accompanied by wheezing,and 30 children with lobar pneumonia without wheezing who were examined by fiberoptic bronchoscopy during the same period were selected as the control group.The levels of EOS,IL-17A,TNF-α and VEGF in peripheral blood of different groups were compared,and the correlation between the four indexes and mycoplasma pneumoniae infection with wheezing in children was analyzed.Results The levels of EOS,IL-17A,TNF-α and VEGF in peripheral blood of the study group were significantly higher than those of the control group,and the differences were statistically significant(P＜0.05).The differences in the levels of EOS,IL-17A,TNF-α and VEGF in the peripheral blood of the three groups were statistically significant(P＜0.05).Specifically,the levels of EOS,IL-17A,TNF-α and VEGF in the wheezing group were significantly higher than those in the non-wheezing group and the control group,and the differences were statistically significant(P＜0.05),and the levels of EOS,IL-17A,TNF-α and VEGF in the non-wheezing group were significantly higher than those in the control group,and the differences were sta-tistically significant(P＜0.05).Pearson correlation analysis showed that the levels of EOS,IL-17A,TNF-α and VEGF in peripheral blood were positively correlated with mycoplasma pneumoniae infection with wheez-ing in children(P＜0.05).Using wheezing as a state variable and plotting the receiver operating characteristic(ROC)curve,it was found that the area under the curve of peripheral blood EOS,IL-17A,TNF-α and VEGF for distinguishing mycoplasma pneumoniae infection with wheezing in children was 0.658,0.960,0.948,and 0.937.Conclusion Peripheral blood EOS,IL-17A,TNF-α,The level of VEGF is positively correlated with Mycoplasma pneumoniae infection with wheezing in children,which could be used for clinical differentiation of mycoplasma pneumoniae infection with wheezing in children.
