Objective: To analyze the epidemiological characteristics and trends of other infectious diarrhea among children under 18 years old in Guangzhou City from 2014 to 2020, and to explore the correlation between climatic factors and the incidence of the disease, so as to provide reference for the early prevention of infectious diseases. Methods: The data of cases of other infectious diarrhea and meteorological data of children under 18 years old in Guangzhou City from 2014 to 2020 were collected through the Chinese Infectious Disease Reporting System and the Guangzhou Meteorological Bureau. The correlation between meteorological factors and the incidence of other infectious diarrhea was analyzed using negative binomial regression. Results: A total of 104 566 cases of other infectious diarrhea among children under 18 years old were reported in Guangzhou City from 2014 to 2020, with a male to female ratio of 1.48∶1. The incidence rate was the highest in 2017 (980.83 per 100 000) and the lowest in 2020 (388.22 per 100 000). The peak of incidence occurred from October to March of the following year. Children under 5 years old accounted for 87.95% of all cases. The number of cases of other infectious diarrhea was negatively correlated with the temperature of the previous 6 days ( IRR = -0.07 ), and positively correlated with the temperature difference on the day of onset ( IRR =0.02) (both P <0.05). It was also positively correlated with the wind speed of the previous 7 days ( IRR=0.07, P <0.05), but there was no statistically significant correlation with the relative humidity on the day of onset ( IRR=-0.00, P >0.05). Conclusions Low temperature, large temperature difference, and high wind speed can increase the risk of other infectious diarrhea. It is necessary to strengthen the prediction and early warning in conjunction with meteorological changes, and warn kindergartens and schools to enhance preventive measures against the clustering of other infectious diarrhea cases.

Objective:To explore the prognostic value of epidermal growth factor receptor (EGFR) co-mutation status in patients with advanced lung adenocarcinoma.Methods:Clinical data of patients with stage ⅢB-Ⅳ lung adenocarcinoma who were first diagnosed in the Department of Respiratory and Critical Care Medicine, First Affiliated Hospital of Hebei North University from January 2019 to December 2022 were collected prospectively. Patients were divided into EGFR mutation group ( n=82) and EGFR co-mutation group ( n=74) according to whether EGFR was combined with other gene mutations. The level of circulating tumor DNA (ctDNA) in peripheral blood was measured by real time fluorescence quantitative PCR. Objective response rate (ORR), disease control rate (DCR), the levels of ctDNA in peripheral blood, and progression-free survival (PFS) were compared between two groups of patients before and after 1 month of treatment. The univariate and multivariate analyses were conducted by Cox proportional hazards regression model. Results:In the EGFR mutation group, there were 45 cases of EGFR19 deletion mutation and 37 cases of EGFR21 mutation. In the EGFR co-mutation group, there were 41 cases of EGFR19 deletion mutation, 33 cases of EGFR21 mutation, 46 cases of TP53 mutation, 16 cases of RB1 mutation, 6 cases of PTEN mutation, 2 cases of MET amplification, 1 case of ERBB2 mutation, 1 case of KRAS mutation, 1 case of RET rearrangement, and 1 case of ALK rearrangement. There were statistically significant differences between the EGFR mutation group and the EGFR co-mutation group in the maximum tumor diameter ( χ2=5.04, P=0.025) and stage ( χ2=3.92, P=0.048). The ORRs of the two groups were 64.63% (53/82) and 37.84% (28/74), respectively, with a statistically significant difference ( χ2=11.19, P<0.001). The DCRs were 96.34% (79/82) and 86.49% (64/74), respectively, with a statistically significant difference ( χ2=4.95, P=0.026). The ctDNA levels in the EGFR mutation group and EGFR co-mutation group after one month of treatment decreased compared to before treatment[2.63 (1.83, 3.30) ng/μl vs. 4.73 (3.92, 5.49) ng/μl, Z=-7.06, P<0.001; 4.26 (2.26, 6.07) ng/μl vs. 5.28 (4.37, 6.09) ng/μl, Z=-5.15, P<0.001], the ctDNA levels in the EGFR co-mutation group were higher than those in the EGFR mutation group before treatment and after 1 month of treatment ( Z=-2.47, P=0.013; Z=-4.29, P<0.001). In the EGFR co-mutation group, the ctDNA levels in peripheral blood of patients who were effectively treated with targeted therapy decreased after 1 month of treatment compared to before treatment [(2.03±0.63) ng/μl vs. (3.92±0.82) ng/μl, t=42.94, P<0.001], the levels of ctDNA in peripheral blood of ineffectively treated patients before and after 1 month of treatment were higher than those of effectively treated patients [(5.84±0.57) ng/μl vs. (3.92±0.82) ng/μl, t=-11.91, P<0.001; (5.87±1.64) ng/μl vs. (2.03±0.63) ng/μl, t=-14.43, P<0.001]. The median PFS of the EGFR mutation group and the EGFR co-mutation group of patients were 10.4 and 8.3 months, respectively, with a statistically significant difference ( χ2=22.28, P<0.001). Univariate analysis suggested that the maximum tumor diameter ( HR=0.10, 95% CI: 0.06-0.16, P<0.001), performance status (PS) score ( HR=0.09, 95% CI: 0.06-0.15, P<0.001), stage ( HR=0.09, 95% CI: 0.05-0.14, P<0.001), pre-treatment ctDNA level ( HR=12.04, 95% CI: 8.21-17.65, P<0.001), ctDNA level after 1 month of treatment ( HR=3.75, 95% CI: 3.10-4.54, P<0.001) and EGFR co-mutations ( HR=2.21, 95% CI: 1.57-3.12, P<0.001) were found to be significant factors affecting the PFS of stage ⅢB-Ⅳ lung adenocarcinoma patients receiving targeted therapy; Multivariate analysis demonstrated that PS score ( HR=0.25, 95% CI: 0.14-0.47, P<0.001), stage ( HR=0.49, 95% CI: 0.24-0.98, P=0.044), pre-treatment ctDNA level ( HR=4.73, 95% CI: 3.08-7.28, P<0.001), ctDNA level after 1 month of treatment ( HR=2.15, 95% CI: 1.65-2.80, P<0.001), and EGFR gene co-mutation ( HR=2.26, 95% CI: 1.40-3.64, P<0.001) were independent risk factors for PFS in stage ⅢB-Ⅳ lung adenocarcinoma patients receiving targeted therapy. Conclusion:Both the EGFR mutation group and EGFR co-mutation group show a decrease in ctDNA levels after targeted therapy for one month compared to before treatment. The median PFS of EGFR co-mutation patients is shorter than that of patients with a single EGFR mutation. PS score, stage, ctDNA levels before and after treatment, and EGFR gene co-mutation are all independent factors affecting PFS in stage ⅢB-Ⅳ lung adenocarcinoma patients after targeted therapy.

Background: SM-like (LSM) genes a family of RNA-binding proteins, are involved in mRNA regulation and can function as oncogenes by altering mRNA stability. However, their roles in B-cell progression and tumorigenesis remain poorly understood. Methods: We analyzed gene expression profiles and overall survival data of 123 patients with mantle cell lymphoma (MCL). The LSM index was developed to assess its potential as a prognostic marker of MCL survival. Results: Five of the eight LSM genes were identified as potential prognostic markers for survival in MCL, with particular emphasis on the LSM.index. The expression levels of these LSM genes demonstrated their potential utility as classifiers of MCL. The LSM.index-high group exhibited both poorer survival rates and lower RNA levels than did the overall transcript profile. Notably, LSM1 and LSM8 were overexpressed in the LSM.index-high group, with LSM1 showing 2.5-fold increase (p < 0.001) and LSM8 depicting 1.8-fold increase (p < 0.01) than those in the LSM.index-low group.Furthermore, elevated LSM gene expression was associated with increased cell division and RNA splicing pathway activity. Conclusions The LSM.index demonstrates potential as a prognostic marker for survival in patients with MCL. Elevated expression of LSM genes, particularly LSM1 and LSM8, may be linked to poor survival outcomes through their involvement in cell division and RNA splicing pathways. These findings suggest that LSM genes may contribute to the aggressive behavior of MCL and represent potential targets for therapeutic interventions.

【Objective】 To explore the significance of automatic transfer of diversion pouches in blood transfusion departments on improving the standardization of quality management. 【Methods】 A total of 16 548 diversion pouches of suspended red blood cells (sRBC) were collected from Blood Transfusion Departments of ten tertiary hospitals in China. The sRBC was supplied by local blood centers from January to March 2021. The diversion pouches were randomly divided into experimental group (n=8 274, using DS-6800A automatic for transferring) and control group (n=8 274, manual transfer). The transfer duration of diversion pouches labels, whole process operation time of diversion pouches, label accuracy after transferring, table cleanliness and accurate transfer rate of diversion pouches of the two groups were recorded and compared. 【Results】 The results of experimental group and control group were as follows: transfer duration(s) of diversion pouch labels was 0.67±0.3 vs 3.67±0.6(P<0.05); whole process operation time was 16.93±0.5 vs 19.85±1 (P<0.05); label accuracy after transferring was 100% (8 274/8 274) vs 97.91% (8 101/8 274); table cleanliness was 99.19% (8 207/8 274) vs 94.39% (7 810/8 274); transfer accuracy was 100%(8 274/8 274) vs 95.85% (7 931/8 274). 【Conclusion】 Automatic transfer of diversion pouches of blood samples can improve the efficiency and quality of the sample transfer, and is conductive to the standardization of internal quality evaluation and control of blood transfusion departments.

Objective:To retrospectively compare the clinical efficacy of two PDE3 inhibitors, oplinone and Milrinone, in order to evaluate which drug has better effects on the improvement of cardiac function, protection of renal function and adverse effects of arrhythmia.Methods:A total of 41 neonates with congenital heart disease after biventricular treatment under cardiopulmonary bypass in the Department of Cardiothoracic Surgery at Soochow University Children's Hospital during 2018-2022 were collected. The experimental group was divided into two groups: Oprilinone(25 cases) and Milinone(16 cases). A retrospective study was conducted on the incidence of renal function, cardiac function improvement and arrhythmia in the children.Results:On the first day after operation, EF in both groups decreased significantly compared with that before operation( P<0.01); On day 4 after surgery, EF in the oprilinone group was significantly higher than that on day 1 after surgery( P<0.01), Milrinone group was slightly higher than that on day 1 after surgery( P<0.05), and EF in oprilinone group was significantly higher than that in Milinone group during the same period( P<0.01); EF in Milinone group continued to increase on day 7 compared with day 4( P<0.01), but there was no significant difference between the two groups. Long-term follow-up showed that there was no significant difference in EF value in the oprilinone intervention group on day 7 after surgery( P<0.05), and the long-term EF in Milinone group was higher than that at 7 days after surgery( P<0.05). The creatinine level in the oprinone intervention group continued to decrease on the 4th and 7th day after surgery( P<0.01; P<0.05); The creatinine level of Milinone group on day 4 after surgery was significantly lower than that on day 1 after surgery( P<0.01), the decrease was not significant on the 7th day after surgery compared with the 4th day after surgery; The creatinine level in the oprilinone group was lower than that in the Milrinone group on day 7 after surgery( P<0.05). The rate of arrhythmia in children was slightly decreased in the intervention group of olplinone. There was no change in the Milinone group. Conclusion:Oplinone improved cardiac function better than Milrinone, and the recovery time to normal cardiac function was shorter. In terms of renal function protection, oplinone was stronger than Milrinone, and the protective effect of oplinone on kidney lasted longer. No significant abnormalities were found with respect to adverse reactions, such as the incidence of arrhythmia.

Mood disorders/psychosis have been associated with dysfunctions in the default mode network (DMN). However, the relative contributions of DMN regions to state and trait disturbances in pediatric bipolar disorder (PBD) remain unclear. The aim of this study was to investigate the possible mechanisms of PBD through brain imaging and explore the influence of psychotic symptoms on functional alterations in PBD patients. Twenty-nine psychotic and 26 non-psychotic PBD patients, as well as 19 age- and sex-matched healthy controls underwent a resting-state functional MRI scan and the data were analyzed by independent component analysis. The DMN component from the fMRI data was extracted for each participant. Spearman's rank correlation analysis was performed between aberrant connectivity and clinical measurements. The results demonstrated that psychotic PBD was characterized by aberrant DMN connectivity in the anterior cingulate cortex/medial prefrontal cortex, bilateral caudate nucleus, bilateral angular gyri, and left middle temporal gyrus, while non-psychotic PBD was not, suggesting further impairment with the development of psychosis. In summary, we demonstrated unique impairment in DMN functional connectivity in the psychotic PBD group. These specific neuroanatomical abnormalities may shed light on the underlying pathophysiology and presentation of PBD.
