Objective To investigate the clinical characteristics and prognosis of pneumococcal meningitis(PM),and drug sensitivity of Streptococcus pneumoniae(SP)isolates in Chinese children.Methods A retrospective analysis was conducted on clinical information,laboratory data,and microbiological data of 160 hospitalized children under 15 years old with PM from January 2019 to December 2020 in 33 tertiary hospitals across the country.Results Among the 160 children with PM,there were 103 males and 57 females.The age ranged from 15 days to 15 years,with 109 cases(68.1% )aged 3 months to under 3 years.SP strains were isolated from 95 cases(59.4% )in cerebrospinal fluid cultures and from 57 cases(35.6% )in blood cultures.The positive rates of SP detection by cerebrospinal fluid metagenomic next-generation sequencing and cerebrospinal fluid SP antigen testing were 40% (35/87)and 27% (21/78),respectively.Fifty-five cases(34.4% )had one or more risk factors for purulent meningitis,113 cases(70.6% )had one or more extra-cranial infectious foci,and 18 cases(11.3% )had underlying diseases.The most common clinical symptoms were fever(147 cases,91.9% ),followed by lethargy(98 cases,61.3% )and vomiting(61 cases,38.1% ).Sixty-nine cases(43.1% )experienced intracranial complications during hospitalization,with subdural effusion and/or empyema being the most common complication[43 cases(26.9% )],followed by hydrocephalus in 24 cases(15.0% ),brain abscess in 23 cases(14.4% ),and cerebral hemorrhage in 8 cases(5.0% ).Subdural effusion and/or empyema and hydrocephalus mainly occurred in children under 1 year old,with rates of 91% (39/43)and 83% (20/24),respectively.SP strains exhibited complete sensitivity to vancomycin(100% ,75/75),linezolid(100% ,56/56),and meropenem(100% ,6/6).High sensitivity rates were also observed for levofloxacin(81% ,22/27),moxifloxacin(82% ,14/17),rifampicin(96% ,25/26),and chloramphenicol(91% ,21/23).However,low sensitivity rates were found for penicillin(16% ,11/68)and clindamycin(6% ,1/17),and SP strains were completely resistant to erythromycin(100% ,31/31).The rates of discharge with cure and improvement were 22.5% (36/160)and 66.2% (106/160),respectively,while 18 cases(11.3% )had adverse outcomes.Conclusions Pediatric PM is more common in children aged 3 months to under 3 years.Intracranial complications are more frequently observed in children under 1 year old.Fever is the most common clinical manifestation of PM,and subdural effusion/emphysema and hydrocephalus are the most frequent complications.Non-culture detection methods for cerebrospinal fluid can improve pathogen detection rates.Adverse outcomes can be noted in more than 10% of PM cases.SP strains are high sensitivity to vancomycin,linezolid,meropenem,levofloxacin,moxifloxacin,rifampicin,and chloramphenicol.[Chinese Journal of Contemporary Pediatrics,2024,26(2):131-138]

Objective: To compare the effectiveness of total laparoscopic versus laparoscopic-assisted distal gastrectomy and investigate the safety and replicability of total laparoscopic distal gastrectomy in older patients. Methods: This was a retrospective cohort study. The inclusion criteria were as follows: (1) age ≥65 years; (2) malignant gastric tumor diagnosed pathologically preoperatively; (3) Eastern Cooperative Oncology Group performance status score 0-1; (4) Grade I-III American Society of Anesthesiologists physical status; (5) preoperative clinical tumor stage I-III; (6) total laparoscopic or laparoscopic-assisted distal gastrectomy performed; and (7) gastrointestinal tract reconstruction using uncut Roux-en-Y or Billroth-II+Braun procedure. Patients who had received neoadjuvant therapy, undergone conversion to open surgery, or had serious comorbidities or incomplete data were excluded. The clinical data of 129 patients who met the above criteria and had undergone laparoscopic surgery for gastric cancer from January 2012 to December 2021 in the Gastrointestinal Cancer Center in the Beijing Cancer Hospital were analyzed. According to the operation method, the patients were divided into total laparoscopic group and laparoscopic-assisted group. Variables studied comprised: (1) surgical procedure and postoperative recovery; (2) postoperative pathological findings; and (3) postoperative complications. Measurement data with skewed distribution are represented as mean(quartile 1, quartile 3). Comparisons between groups were evaluated using the Mann-Whitney U test. Results: After propensity score matching in a 1:1 ratio, there were 40 patients in the total laparoscopic distal gastrectomy group and 40 in the laparoscopic-assisted distal gastrectomy group. Baseline characteristics did not differ significantly between the two groups (all P>0.05).Compared with the laparoscopic-assisted group, the total laparoscopic group had shorter main incisions (4.1±1.0 cm vs. 8.5±2.8 cm, t=9.375, P<0.001), time to fluid intake [4.0 (3.0, 4.8) days vs. 5.0 (4.0, 6.0) days, Z=2.167, P=0.030], and duration of indwelling abdominal drainage catheter [6.0 (6.0, 7.0) days vs. 7.0 (6.0, 8.0) days, Z=2.323, P=0.020]. Numerical Rating Scale scores on postoperative days 1 and 2 were higher in the total laparoscopic than the laparoscopic-assisted group [2.5 (1.0, 3.0) vs. 1.5 (1.0, 2.0), Z=1.980, P=0.048; 2.0 (1.0, 3.0) vs. 1.0 (1.0, 2.0), Z=2.334, P=0.020, respectively]. However, there were no significant differences between the groups in operation time, intraoperative blood loss, white blood cell count, hemoglobin concentration, or albumin concentration on postoperative day 1, time to ambulation, mean time to bowel movement, postoperative admission to the intensive care unit, length of postoperative hospital stay, or Numerical Rating Scale scores on postoperative day 3 (all P>0.05). There were also no significant differences between the two groups in maximum tumor diameter, pathological tumor type, total number of lymph nodes dissected, or total number of positive lymph nodes (all P>0.05). The incidence of postoperative complications was 15.0% (6/40) in the total laparoscopic group and the laparoscopic-assisted group; these differences are not significant (χ²<0.001, P>0.999). Conclusions: Compared with laparoscopic-assisted radical gastrectomy for distal gastric cancer, total laparoscopic surgery has the advantages of shorter incision, shorter time to fluid intake, and shorter duration of indwelling abdominal drainage catheter in older patients (age ≥65 years). Total laparoscopic radical gastrectomy for distal gastric cancer does not increase the risk of postoperative complications and could therefore be performed more frequently.

Objective: To describe the distribution characteristics of tea consumption in adult twins recruited in the Chinese National Twin Registry (CNTR) and provide clues to genetic and environmental influences on tea consumption. Methods: Enrolled in CNTR during 2010-2018, 25 264 twin pairs aged 18 years and above were included in subsequent analysis. Random effect models were used to estimate tea consumption in the population and regional distribution characteristics. The concordance rate of the behavior and difference in consumption volume of tea within pairs were also described. Results: The mean age of all subjects was (35.38±12.45) years old. The weekly tea consumers accounted for 17.0%, with an average tea consumption of (3.36±2.44) cups per day. The proportion of weekly tea consumers was higher among males, 50-59 years old, southern, urban, educated, and the first-born in the twin pair (P<0.05), and lower among unmarried individuals (P<0.001). Within-pair analysis showed that the concordance rate of tea consumption of monozygotic (MZ) twins was higher than that of dizygotic (DZ) twins and the overall heritability of tea consumption was 13.45% (11.38%-15.51%). Stratified by the characteristics mentioned above, only in males, the concordance rate of MZ showed a tendency to be greater than that of DZ (all P<0.05). The differences in consumption volume of tea within twin pairs were minor in MZ among males (P<0.05), while the differences were not significant in female twins. Conclusion: There were discrepancies in the distribution of tea consumption among twins of different demographic and regional characteristics. Tea consumption was mainly influenced by environmental factors and slightly influenced by genetic factors. The size of genetic factors varied with gender, age, and region, and gender was a potential modified factor.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

In this study a D-galactose-induced aging rat model combined with ¹H NMR of serum and liver metabolomics were used to explore the anti-aging effect and the potential metabolic regulatory mechanism of Scutellaria baicalensis Georgi leaves. All procedures involving animal treatment were approved according to the Committee on the Ethics of Animal Experiments of Shanxi University. The results of physical characteristics, an open field test and serum biochemical indexes indicated that Scutellaria baicalensis Georgi leaves had an anti-aging effect that could ameliorate the characteristics of aging rats such as acquired hair loss and slow response, improve the spontaneous activity of aging rats, and decrease lipid peroxidation and glycosylation damage induced by D-galactose. Serum and liver metabolomics further revealed that Scutellaria baicalensis Georgi leaves could decrease serum and liver metabolism disturbances in aging rats, mainly through different metabolites and metabolic pathways. Specifically, 12 differential metabolites including glutamine and glutamate, 11 metabolic pathways including D-glutamine and D-glutamate metabolism and alanine, aspartate and glutamate metabolism in serum were significantly altered after the treatment. Simultaneously, five differential metabolites such as α-glucose and β-glucose, two metabolic pathways that are glycolysis or gluconeogenesis, and starch and sucrose metabolism in the liver were markedly altered.
