Aim To explore the mechanism of Yanghe decoction-containing serum on the migration and inva-sion of MCF-7 breast cancer cells in a co-culture sys-tem with M2 tumor-associated macrophages(TAMs)based on the paracrine epidermal growth factor(EGF)/epidermal growth factor receptor(EGFR)sig-naling pathway.Methods The M2-type TAMs model was induced from THP-1 monocytic cell line through in vitro treatment with phorbol 12-myristate 13-acetate(PMA)and recombinant human macrophage colony-stimulating factor(M-CSF).The MCF-7 cells were co-cultured with M2-type TAMs using a Transwell non-contact co-culture system to evaluate their effects on migration and invasion.Subsequently,the cells were intervened with serum containing Yanghe decoction,and the proliferation of MCF-7 cells was detected using the CCK-8 assay,while their lateral migration ability was assessed through scratch assays.The invasion and vertical migration abilities of the cells were evaluated separately using Transwell assays,and the concentra-tion of EGF was measured using ELISA.Finally,the expression of EGFR,MCP-1,and MMP9 proteins was detected using Western blot.Results Compared to the control group,Yanghe decoction-containing serum in-hibited the proliferation of MCF-7 cells before and after co-culture.The serum reduced the scratch healing a-bility before and after co-culture and decreased their migration and invasion abilities.Additionally,Yanghe decoction-containing serum reduced the levels of EGF before and after co-culture and decreased the expres-sion of EGFR,MCP-1,and MMP9 proteins before and after+co-culture.Conclusion Yanghe decoction-containing serum can inhibit the migration and invasion of breast cancer MCF-7 cells before and after co-cul-ture with M2 TAMs.This effect may be related to the inhibition of the EGF-EGFR signaling pathway.

Objective To examine the changing antimicrobial resistance profile of Enterobacter spp.isolates in 53 hospitals across China from 2015 t0 2021.Methods The clinical isolates of Enterobacter spp.were collected from 53 hospitals across China during 2015-2021 and tested for antimicrobial susceptibility using Kirby-Bauer method or automated testing systems according to the CHINET unified protocol.The results were interpreted according to the breakpoints issued by the Clinical & Laboratory Standards Institute(CLSI)in 2021(M100 31st edition)and analyzed with WHONET 5.6 software.Results A total of 37 966 Enterobacter strains were isolated from 2015 to 2021.The proportion of Enterobacter isolates among all clinical isolates showed a fluctuating trend over the 7-year period,overall 2.5％in all clinical isolates amd 5.7％in Enterobacterale strains.The most frequently isolated Enterobacter species was Enterobacter cloacae,accounting for 93.7％(35 571/37 966).The strains were mainly isolated from respiratory specimens(44.4±4.6)％,followed by secretions/pus(16.4±2.3)％and urine(16.0±0.9)％.The strains from respiratory samples decreased slightly,while those from sterile body fluids increased over the 7-year period.The Enterobacter strains were mainly isolated from inpatients(92.9％),and only(7.1±0.8)％of the strains were isolated from outpatients and emergency patients.The patients in surgical wards contributed the highest number of isolates(24.4±2.9)％compared to the inpatients in any other departement.Overall,≤ 7.9％of the E.cloacae strains were resistant to amikacin,tigecycline,polymyxin B,imipenem or meropenem,while ≤5.6％of the Enterobacter asburiae strains were resistant to these antimicrobial agents.E.asburiae showed higher resistance rate to polymyxin B than E.cloacae(19.7％vs 3.9％).Overall,≤8.1％of the Enterobacter gergoviae strains were resistant to tigecycline,amikacin,meropenem,or imipenem,while 10.5％of these strains were resistant to polycolistin B.The overall prevalence of carbapenem-resistant Enterobacter was 10.0％over the 7-year period,but showing an upward trend.The resistance profiles of Enterobacter isolates varied with the department from which they were isolated and whether the patient is an adult or a child.The prevalence of carbapenem-resistant E.cloacae was the highest in the E.cloacae isolates from ICU patients.Conclusions The results of the CHINET Antimicrobial Resistance Surveillance Program indicate that the proportion of Enterobacter strains in all clinical isolates fluctuates slightly over the 7-year period from 2015 to 2021.The Enterobacter strains showed increasing resistance to multiple antimicrobial drugs,especially carbapenems over the 7-year period.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To explore the effects of different side tension pneumothorax on hemodynamics in pigs,providing data support for the optimization of on-site first-aid procedures for pneumothorax.Methods Twelve Bama pigs were randomly divided into left-sided tension pneumothorax group and right-sided tension pneumothorax group(6 in each group).During the occurrence of pneumothorax and as the pleural pressure gradually increases by 1 mmHg increments,the key indicators were collected using pulse indicator continuous cardiac output(PICCO)technology:hemodynamic indicators[global ejection fraction(GEF),cardiac output(CO),global end-diastolic volume(GEDV),intrathoracic blood volume(ITBV),stroke volume(SV),mean arterial pressure(MAP)],basic vital signs[heart rate(HR),diastolic blood pressure(DBP),systolic blood pressure(SBP)],and arterial blood gas parameters[partial pressure of oxygen(PO2),partial pressure of carbon dioxide(PCO2)].Mediastinal localization was subsequently performed using radiographs.Differences were investigated through comparison between the two groups and within each group before and after the procedure.Results By comparing the hemodynamic changes and X-ray examination results,twelve Bama pigs tension pneumothorax models were successfully constructed.Hemodynamic analysis showed that in left-sided tension pneumothorax model when the pleural pressure reached 8 mmHg,SBP,DBP,MAP,CO,GEF,SV,GEDV and ITBV were significantly lower than those during the occurrence of ipsilateral pneumothorax(P<0.05).In right-sided tension pneumothorax model,when the pleural pressure reached about 3 mmHg,SBP,DBP,MAP,SV,GEDV,and ITBV were significantly lower than those during the occurrence of ipsilateral pneumothorax(P<0.05).Blood gas analysis showed that at 8 mmHg for left-sided and 3 mmHg for right-sided tension pneumothorax,compared with the occurrence of their respective ipsilateral pneumothorax,PO2 was significantly lower(P<0.05)and PCO2 was significantly higher(P<0.05).Conclusions There are different effects on hemodynamics in different side tension pneumothorax.Compared with left tension pneumothorax,right tension pneumothorax can lead to serious consequences under a smaller pleural pressure.Different side tension pneumothorax models can be constructed according to the actual situation when performing pneumothorax related experiments.

Purpose: The purpose of this study was to investigate the prevalence and risk factors of overactive bladder (OAB) in young adults and to explore the influence of OAB on mental health. Methods: Between October 2019 and January 2020, 14,010 anonymous questionnaires were distributed to freshmen at 2 universities in Henan, China. The students came from all over the country. The questionnaire included general items and information necessary to calculate the overactive bladder symptom score, the Chinese version of the Pittsburgh Sleep Quality Index (PSQI) score, Self-Esteem Scale (SES) score, and Self-Rating Depression Scale (SDS) score. The relationships between the prevalence of OAB and its risk factors were evaluated. Results: The overall prevalence of OAB was 6.0%, with 4.3% of participants characterized as having dry OAB and 1.7% as having wet OAB. The prevalence of mild OAB was 5.5%, and that of moderate OAB was 0.5%; no severe OAB was observed. Higher prevalence rates of OAB were found among women, respondents with constipation, and respondents with primary nocturnal enuresis (PNE) (P <0.05). Compared to healthy controls, the OAB group exhibited a higher mean SDS score (52.12±8.986 vs. 47.71±9.399, P<0.001) and mean PSQI score (5.28±2.486 vs. 4.27±2.431, P<0.001), but a lower mean SES score (27.78±3.599 vs. 29.57±4.109, P<0.001). Conclusions OAB significantly affects the mental health of young adults. Female sex, constipation, and PNE are risk factors for OAB.

Objective To investigate the value of different immune and inflammatory indices in predicting the survival outcome of patients with intrahepatic cholangiocarcinoma (ICC) after curative-intent resection. Methods A retrospective analysis was performed for the case data of 122 patients with ICC who underwent curative-intent resection in Affiliated Hospital of Weifang Medical University and Tianjin Medical University Cancer Institute and Hospital from January 2012 to December 2017 to analyze the correlation of neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), systemic immune-inflammation index (SII), prognostic inflammation index (PII), inflammation score (IS), and systemic inflammation score (SIS) with the disease-free survival (DFS) and overall survival of ICC patients after surgery, and the value of the above indices in predicting prognosis was evaluated. The chi-square test or the Fisher's exact test was used for comparison of categorical data between groups. The Kaplan-Meier method was used to plot survival curves, and the Log-rank test was used for comparison between groups; the Cox regression model was used for univariate and multivariate analyses, and hazard ratio ( HR ) and 95% confidence interval [ CI ] were calculated. Results The univariate survival analysis showed that NLR ( HR =2.212, P =0.004), LMR ( HR =0.403, P =0.012), PII ( HR =3.013, P < 0.001), prognostic nutritional index (PNI) ( HR =0.530, P =0.019), IS ( HR =1.809, P =0.001), SII ( HR =2.107, P =0.002), and SIS ( HR =2.225, P < 0.001) were predictive factors for postoperative DFS of patients with ICC, and NLR ( HR =2.416, P =0.009), LMR ( HR =0.297, P =0.008), PII ( HR =3.288, P < 0.001), PNI ( HR =0.292, P =0.003), IS ( HR =2.048, P =0.002), SII ( HR =1.839, P =0.049), and SIS ( HR =2.335, P < 0.001) were predictive factors for postoperative OS of patients with ICC. The multivariate survival analysis showed that high levels of PII ( HR =2.146, P =0.035) and SIS ( HR =2.511, P < 0.001) were independent influencing factors for postoperative DFS of ICC patients, and high levels of PII ( HR =2.981, P =0.009), PNI ( HR =0.261, P =0.002), and SIS ( HR =2.294, P =0.010) were independent influencing factors for postoperative OS. The patients with a high level of PII tended to have advanced tumor T stage ( χ 2 =8.777, P =0.003) and M stage ( P =0.029), and the patients with high-grade SIS tended to have advanced N stage ( χ 2 =9.985, P =0.030) and M stage ( χ 2 =8.574, P =0.012). Conclusion Among the various inflammation indices, PII and SIS are recommended for preoperative stratification and prediction of the outcome of ICC patients after curative-intent resection.

Objective: To compare the short-term efficacy and long-term prognosis of laparoscopic and laparotomy radical resection for gallbladder cancer(GBC). Methods: From January 2010 to December 2020,the clinical data and survival information for 133 patients who underwent radical resection of GBC at the Department of Hepatopancreatobiliary Surgery,Zhejiang Provincial People's Hospital,were retrospectively collected. Eighty patients(23 males and 57 females) underwent laparoscopic radical resection and had a median age(M(IQR)) of 66.0(12.8)years(range:28.0 to 82.0 years). Fifty-three patients(45 males and 8 females) who received laparotomy were 63.0(6.0)years old(range:45.0 to 80.0 years old). There were no significant differences in age,gender,body mass index,preoperative albumin,preoperative total bilirubin,N stages,vascular invasion,peri-neural invasion or tumor differentiation between the laparoscopic and laparotomy group(all P>0.05). But there were significant differences in preoperative CA19-9(Z=-2.955, P=0.003), preoperative ALT level(Z=-2.801,P=0.031) and T stage (χ²=19.110,P=0.007) between the two groups. A non-parametric test was used for quantitative data. χ² test or Fisher exact probability method was used for count data. Results: Patients in the laparoscopic group did not differ from those in the laparotomy group in terms of length of operation,number of lymph node yield,number of positive lymph nodes,the incidence of intraoperative gallbladder rupture,incidence of postoperative bile leakage,abdominal bleeding or abdominal infection,30-day mortality,90-day mortality, the incidence of incision implantation or peritoneal cavity metastasis(all P>0.05). Patients in the laparoscopic group showed less intraoperative bleeding(100.0(200.0)ml vs. 400.0(250.0)ml)(Z=-5.260,P<0.01),fewer days with drainage tube indwelling(6.0(3.8)days vs. 7.0(4.0)days)(Z=-3.351, P=0.001), and fewer postoperative days in hospital(8.0(5.0)days vs. 14.0(7.5)days)(Z=-6.079,P<0.01) than those in the laparotomy group. Patients in the laparoscopic group displayed better overall survival (P<0.01) and progression-free survival (P<0.01). Subgroup analysis for GBC of T1b-T2 and T3 stages revealed comparable overall survival and progression-free survival between the laparoscopic and laparotomy groups (P>0.05). Conclusions: Laparoscopic radical resection can achieve long-term survival for GBC comparable to that with open surgery. Laparoscopic radical resection has advantages over open surgery regarding surgical trauma and postoperative recovery.

Objective: We investigated changes in the intestinal flora of children with Mycoplasma pneumoniae pneumonia (MPP). Methods: Between September 2019 and November 2019, stool samples from 14 children with MPP from The Fourth Hospital of Baotou city, Inner Mongolia Autonomous Region, were collected and divided into general treatment (AF) and probiotic (AFY) groups, according to the treatment of "combined Bifidobacterium, Lactobacillus, Enterococcus, and Bacillus cereus tablets live". High-throughput 16S rDNA sequencing was used to identify intestinal flora. Results: Intestinal flora abundance and diversity in children with MPP were decreased. Both Shannon and Simpson indices were lower in the AF group when compared with healthy controls ( P < 0.05). When compared with healthy controls, the proportion of Enterorhabdus was lower in the AF group, while the proportion of Lachnoclostridium was higher ( P < 0.05). The proportion of Bifidobacteria and Akkermansia was lower in the AFY group but Enterococcus, Lachnoclostridium, Roseburia, and Erysipelatoclostridium proportions were higher. The proportion of Escherichia coli- Shigella in the AFY group after treatment was decreased ( P < 0.05). Conclusions The intestinal flora of children with MPP is disturbed, manifested as decreased abundance and diversity, and decreased Bifidobacteria. Our probiotic mixture partly improved intestinal flora disorders.

Purpose: This study aimed to investigate the prevalence, risk factors, and effects of primary nocturnal enuresis (PNE) on physical and mental health in young adults in mainland China. Methods: An anonymous questionnaire was used to collect information including the sociodemographic characteristics, history of PNE, family history, daytime voiding symptoms, Pittsburgh Sleep Quality Index (PSQI) scores, Self-Esteem Scale (SES), and Self-Rating Depression Scale (SDS). A total of 22,500 university students from 23 provinces and 368 cities in mainland China were included. Results: In total, 21,082 questionnaires were collected, and 20,345 of them qualified for statistical analysis. The PNE prevalence was 1.17%, and the distribution of monosymptomatic nocturnal enuresis (MNE) and nonmonosymptomatic nocturnal enuresis (NMNE) was 66.1% and 33.9%, respectively. In total, 28% of respondents with PNE reported bedwetting daily, 31.6% between 1 and 7 times weekly, and 40.4% between 1 and 4 times monthly; 80% of PNE cases had no history of treatment. The prevalence of PNE in patients with a family history, frequency, urgency, urinary incontinence, and recurrent urinary tract infections was significantly higher than in those without these conditions (P<0.001). PNE was significantly correlated with the PSQI total score (sleep quality) (P=0.011). The SES score was lower and the SDS was higher (P<0.001) in the PNE group than in those without PNE. Conclusions In mainland China, the PNE prevalence among young adults was found to be high, and PNE had significant effects on physical and mental health. Risk factors included a family history, daytime voiding symptoms, and lack of treatment.

Objective:To observe any effect of intermittent theta burst stimulation (iTBS) of the prefrontal lobe on dysphagia and impaired cognition, and to explore the neural mechanisms involved.Methods:Twenty-eight patients with dysphagia and mild cognitive impairment were randomly divided into an iTBS group of 16 and a control group of 11. The iTBS group received 20 minutes of iTBS (2 seconds on and 8 seconds off) of the right dorsal lateral prefrontal cortex (DLPFC) once daily for 2 weeks, with the intensity at 80% of the resting movement threshold of the right abductor pollicis brevis, while the control group was given sham iTBS. Before and after the treatment, both groups′ cognitive functioning was evaluated using the Montreal Cognitive Assessment Scale (MoCA), a trial marking test, a digit span test and a Stroop color word test. Video-fluoroscopy was used to record oral transmission times (OTTs), hyoid bone anterior displacement and hyoid bone upward displacement during swallowing. Resting-state functional magnetic resonance imaging measured the amplitude of low-frequency fluctuation (ALFF), regional homogeneity (ReHo) and functional connectivity in the patients′ brains.Results:Before the treatment there was no significant difference in the average indices of cognition or swallowing function between the 2 groups. Afterward the average MoCA score had increased significantly in both groups, with the improvement in the iTBS group significantly greater than that of the controls. Average OTT had shortened significantly in both groups, with significantly greater improvement in the iTBS group. The magnetic resonance imaging showed that after iTBS treatment, local excitation indicators and functional connections in several brain regions had changed. ALFF and ReHo in the right anterior cuneus had increased, ReHo in the left middle temporal gyrus, the orbital region of the left inferior frontal gyrus and the left middle cingulate gyrus had decreased, and functional connectivity in the right DLPFC, the bilateral cuneus and the right middle cingulate gyrus had increased.Conclusions:Two weeks of intermittent TBS of the right DLPFC can improve the swallowing and cognition of persons with dysphagia. Functional reorganization of brain networks may be one of the neural mechanisms involved.
