ObjectiveTo investigate the effects of probiotics combined with bismuth quadruple therapy （BQT） on clinical efficacy、gastrointestinal adverse reactions and intestinal flora in Helicobacter pylori （HP） positive patients. MethodsThe patients who were positive for HP from May 2023 to July 2023 in the department of gastroenterology of Shanghai first people's hospital were randomly divided into2 groups with 40 people in each group. The probiotic group was given 2 weeks of quadruple therapy with probiotics and standard BQT， followed by 4 weeks of oral probiotics after quadruple discontinuation. The placebo group was given 2 weeks of probiotic placebo and standard BQT， followed by 4 weeks of oral probiotic placebo. ¹³C urea breath test was used to evaluate the clinical efficacy， gastrointestinal symptoms rating Scale was used to evaluate the gastrointestinal adverse reactions of patients before and after the intervention， and microbial diversity 16S rDNA sequencing technology was used to detect the level of intestinal flora of patients before and after the intervention. ResultsThere was no significant difference in the eradication rate between the two groups （P>0.05）. Before the intervention， there was no significant difference in the scores of the gastrointestinal symptom rating scale between the probiotic group and the placebo group. After the intervention， patients in the probiotic group had significantly lower pain scores on acid reflux （1.10±0.30 vs 1.35±0.53， P<0.05） and stomach or abdominal hunger than in the placebo group （1.07±0.26 vs 1.30±0.52， P<0.05）. Through the before-and-after comparison of the probiotic group， the scores of abdominal pain （1.24±0.44 vs 1.58±0.71， P<0.05）， stomach or abdominal hunger （1.07±0.26 vs 1.27±0.45， P<0.05） and dry and hard stool （1.24±0.49 vs 1.48±0.75，P<0.05） were significantly lower in the probiotic group than before the intervention in the probiotic group. ConclusionProbiotics combined with BQT can improve the gastrointestinal adverse reactions and intestinal flora disorders in the process of quadruple drug therapy， but it does not improve the eradication rate of HP.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

OBJECTIVE: To observe the effects of electro-scalp acupuncture （ESA） on the expression of microglial markers CD206 and CD32, as well as interleukin (IL)-6, IL-1β, and IL-10 in the ischemic cortex of rats with ischemic stroke, and to explore the mechanisms of ESA on alleviating inflammatory damage of ischemic stroke. METHODS: Sixty 7-week-old male SD rats were randomly selected, with 15 rats assigned to a sham surgery group. The remaining rats were treated with suture method to establish rat model of middle cerebral artery occlusion (MCAO). The rats with successful model were randomly divided into a model group, a VitD₃ group, and an ESA group, with 15 rats in each group. In the ESA group, ESA was performed bilaterally at the "top-temporal anterior oblique line" with disperse-dense wave, a frequency of 2 Hz/100 Hz, and an intensity of 1 mA. Each session lasted for 30 min, once daily, for a total of 7 days. The VitD₃ group were treated with intragastric administration of 1,25-dihydroxyvitamin D₃ (1,25-VitD₃) solution (3 ng/100 g), once daily for 7 days. The neurological deficit scores and neurobehavioral scores were assessed before and after the intervention. After the intervention, the brain infarct volume was evaluated using 2,3,5-triphenyltetrazolium chloride (TTC) staining. Immunofluorescence double staining was performed to detect the protein expression of CD32 and CD206 in the ischemic cortex. Western blot analysis was conducted to measure the protein expression of IL-6, IL-1β, and IL-10 in the ischemic cortex. RESULTS: Compared with the sham surgery group, the model group showed increased neurological deficit scores and neurobehavioral scores (P<0.01), increased brain infarct volume (P<0.01), increased protein expression of CD32, IL-6, and IL-1β in the ischemic cortex (P<0.01), and decreased protein expression of CD206 and IL-10 in the ischemic cortex (P<0.01). Compared with the model group, both the ESA group and the VitD₃ group showed decreased neurological deficit scores and neurobehavioral scores (P<0.01), reduced brain infarct volume (P<0.01), decreased protein expression of CD32, IL-6, and IL-1β in the ischemic cortex (P<0.01), and increased protein expression of CD206 and IL-10 in the ischemic cortex (P<0.01). Compared with the VitD₃ group, the ESA group had lower neurological deficit score (P<0.05), larger brain infarct volume (P< 0.05), and lower protein expression of CD32, CD206, IL-1β, and IL-10 in the ischemic cortex (P<0.01, P<0.05). CONCLUSION ESA could improve neurological function in MCAO rats, and its mechanism may be related to promoting microglial M1-to-M2 polarization and alleviating inflammatory damage.

Objective: To establish and validate a nomogram-based predictive model for idiopathic hyperaldosteronism (IHA). Methods: This cross-sectional study was conducted with the collected clinical and biochemical data of patients with primary aldosteronism (PA) including 249 patients with unilateral primary aldosteronism (UPA) and 107 patients with IHA, who were treated at the Department of Endocrinology of the First Affiliated Hospital of Chongqing Medical University from November 2013 to November 2022. Plasma aldosterone concentration (PAC) and plasma renin concentration (PRC) were measured by chemiluminescence. Stepwise regression analysis was applied to select the key predictors of IHA, and a nomogram-based scoring model was developed. The model was validated in another external independent cohort of patients with PA including 62 patients with UPA and 43 patients with IHA, who were diagnosed at the Department of Endocrinology, First Affiliated Hospital of Zhengzhou University. An independent-sample t test, Mann-Whitney U test, and χ² test were used for statistical analysis. Results: In the training cohort, in comparison with the UPA group, the IHA group showed a higher serum potassium level [M(Q₁, Q₃), 3.4 (3.1, 3.8) mmol/L vs. 2.7 (2.1, 3.1) mmol/L] and higher PRC [4.0 (2.1, 8.2) mU/L vs. 1.5 (0.6, 3.4) mU/L] and a lower PAC post-saline infusion test (SIT) [305 (222, 416) pmol/L vs. 720 (443, 1 136) pmol/L] and a lower rate of unilateral adrenal nodules [33.6% (36/107) vs. 81.1% (202/249)]; the intergroup differences in these measurements were statistically significant (all P<0.001). Serum potassium level, PRC, PAC post-SIT, and the rate of unilateral adrenal nodules showed similar performance in the IHA group in the validation cohort. After stepwise regression analysis for all significant variables in the training cohort, a scoring model based on a nomogram was constructed, and the predictive parameters included the rate of unilateral adrenal nodules, serum potassium concentration, PAC post-SIT, and PRC in the standing position. When the total score was ≥14, the model showed a sensitivity of 0.65 and specificity of 0.90 in the training cohort and a sensitivity of 0.56 and specificity of 1.00 in the validation cohort. Conclusion: The nomogram was used to successfully develop a model for prediction of IHA that could facilitate selection of patients with IHA who required medication directly.

SARS-CoV-2 infection causes complicated clinical manifestations with variable multi-organ injuries, however, the underlying mechanism, in particular immune responses in different organs, remains elusive. In this study, comprehensive transcriptomic alterations of 14 tissues from rhesus macaque infected with SARS-CoV-2 were analyzed. Compared to normal controls, SARS-CoV-2 infection resulted in dysregulation of genes involving diverse functions in various examined tissues/organs, with drastic transcriptomic changes in cerebral cortex and right ventricle. Intriguingly, cerebral cortex exhibited a hyperinflammatory state evidenced by significant upregulation of inflammation response-related genes. Meanwhile, expressions of coagulation, angiogenesis and fibrosis factors were also up-regulated in cerebral cortex. Based on our findings, neuropilin 1 (NRP1), a receptor of SARS-CoV-2, was significantly elevated in cerebral cortex post infection, accompanied by active immune response releasing inflammatory factors and signal transmission among tissues, which enhanced infection of the central nervous system (CNS) in a positive feedback way, leading to viral encephalitis. Overall, our study depicts a multi-tissue/organ transcriptomic landscapes of rhesus macaque with early infection of SARS-CoV-2, and provides important insights into the mechanistic basis for COVID-19-associated clinical complications.

Objective To analyze the epidemiological characteristics of hepatitis A in Guangxi from 2010 to 2020, and to provide a scientific basis for formulating effective prevention and control strategies. Methods Descriptive epidemiological method was used to analyze the incidence data of hepatitis A in Guangxi from 2010 to 2020. Results From 2010 to 2020, a total of 8,742 cases of hepatitis A were reported in Guangxi, with an average annual incidence rate of 1.66 /100,000. There were 5 298 male cases (60.60%), and 3,444 female cases (39.40%). The incidence rate decreased from 2.73/100 000 in 2010 to 1.38/100 000 in 2020. The onset seasonality was strong in 2010, but there was no obvious seasonality in other years. A total of 5 891 cases (67.39%) were aged from 25 to 64 years. Farmers accounted for 59.79% of the cases. A total of 7 hepatitis A outbreaks were reported during 2010-2020, including 273 cases，accounting for 3.12% of the total cases．The incidence rates of hepatitis A in Hezhou (3.97/100 000), Wuzhou (2.98/100 000), Hechi (2.44/100 000), Guigang (2.00/100 000) and Beihai (1.79/100 000) were relatively higher than other places. Conclusion The number of reported hepatitis A cases in Guangxi has been declining year by year, and the prevention and control measures of hepatitis A vaccine prevention are effective. The surveillance of hepatitis A should be strengthened, and prevention and control strategies should be formulated for high-risk areas and key populations.

To investigate the association of pancreatic steatosis with coronary atherosclerosis in patients with type 2 diabetes mellitus (T2DM). Patients with T2DM who underwent coronary computed tomography angiography(CCTA)in our center due to chest pain were enrolled from January 2016 to February 2019. According to the CCTA findings,patients were divided into normal group,mild-to-moderate coronary atherosclerosis group and severe coronary atherosclerosis group. CT attenuation of pancreas and spleen was measured on abdominal non-enhanced CT,and the CT attenuation indexes including the difference between pancreatic and splenic attenuation (P-S) and the ratio of pancreas-to-spleen attenuation (P/S) were calculated. Analysis of variance or Kruskal-Wallis rank test were used to assess differences among each group. Logistic regression analysis was used to analyze the risk factors of severe coronary stenosis. The accuracy of P/S in predicting severe coronary artery stenosis was assessed by receiver operator characteristic (ROC) curve analysis. A total of 173 consecutive T2DM patients were enrolled. These patients included 27 patients with normal coronary artery (15.6%),124 patients with mild to moderate stenosis (71.7%),and 22 patients with severe stenosis (12.7%). There were significant differences in CT attenuation of pancreas (=11.543,=0.003),P-S (=11.152,=0.004) and P/S (=11.327,=0.004) among normal coronary artery group,mild and moderate stenosis group,and severe stenosis group. The CT attenuation of pancreatic head,body,and tail significantly differed in patients with coronary artery stenosis (=14.737,=0.001). After adjusting for confounding factors,multiple Logistic regression showed that P/S (=0.062,95%=0.008-0.487,=0.008) was still significantly associated with the severe coronary artery stenosis. The area under the ROC curve of P/S for the diagnosis of severe coronary artery stenosis was 0.701,and the optimal cutoff point was 0.660. CT attenuation of pancreas and CT attenuation indexes are associated with the severity of coronary stenosis in T2DM patients,suggesting that pancreatic steatosis may be used as one of the indicators for predicting severe coronary artery stenosis.

OBJECTIVE: To investigate whether there is a difference in cerebellar development between appropriate -for-gestational-age (AGA) infants and small-for-gestational-age (SGA) infants. METHODS: A total of 165 AGA infants and 105 SGA infants, with a gestational age of 26-40 weeks, were enrolled in this study. Within 24-48 hours after birth, ultrasound examination was performed to measure the transverse diameter of the cerebellum, the height of the vermis, the area of the vermis, the perimeter of the vermis, and the area and perimeter of the cerebellum on transverse section. A Pearson correlation analysis was used to investigate the correlation between cerebellar measurements and gestational age. RESULTS: In both AGA and SGA infants, all cerebellar measurements were positively correlated with gestational age (r=0.50-0.81, P<0.05). In AGA and SGA infants, there were no significant differences in the measurements between the 25-27 weeks, 28-30 weeks, and 31-33 weeks of gestational age subgroups (P>0.05), while in the 34-36 weeks and 37-40 weeks subgroups, the SGA infants had significantly lower measurements than the AGA infants (P<0.05). CONCLUSIONS The SGA infants with a gestational age of <34 weeks have intrauterine cerebellar development similar to AGA infants, but those with a gestational age of ≥34 weeks have poorer intrauterine cerebellar development than AGA infants.
