Objective:To investigate the effects of oral probiotics on intestinal microbiota and cognitive dysfunction in breast cancer chemotherapy patients. Methods:Thirty breast cancer patients who received anthracycline chemotherapy between December 2021 and June 2022 in the Department of Oncology, the First Affiliated Hospital of Bengbu Medical University were included in this study. The patients were randomly divided into the observation and control groups (15 cases per group). During chemotherapy, the observation group was additionally given oral probiotics. The fecal microbiota compositions before and after chemotherapy were detected using 16S rDNA sequencing. The changes in patients' subjective and objective cognitive function levels were evaluated by Montreal Cognitive Assessment (MoCA) and Functional Assessment of Cancer Therapy-Cognitive (FACT-Cog), respectively. Results:The microbiota diversity, as indicated by the Chao, Ace, Shannon and Simpson indices, showed no significant difference between two groups (P>0.05). As compared with the control group, the relative abundance of the genus Actinomyces in the feces was significantly higher than in the observation group (P<0.05). By contrast, the relative abundance of the genera Acetoanaerobium, Lachnospiracea_incertae_sedis, and unclassified_Frankineae bacteria was significantly lower in the observation group (P<0.05). The total scores of the objective and subjective cognitive function as well as the scores of each dimension in both groups were markedly decreased after chemotherapy (P<0.05). The scores in the observation group were higher than those in the control group after chemotherapy (P<0.05). During chemotherapy, the presence of the gastrointestinal adverse reactions (constipation, nausea and vomiting, diarrhea and abdominal distension) in the observation group were significantly lower than in control group (P<0.05). Conclusion:Oral probiotics could improve the cognitive impairment and reduce the presence of the gastrointestinal side effects in the breast cancer patients receiving chemotherapy, which may be caused by modulating the intestinal microbiota.

Objective To establish the diagnostic criteria for psoriasis vulgaris of spleen deficiency with dampness accumulation syndrome by using the methods of literature research,subjective experts'experience evaluation and mathematical statistical analysis together.Methods An alternative item pool of symptoms and signs related to psoriasis vulgaris of spleen deficiency with dampness accumulation syndrome was constructed on the basis of the results of literature research.A four-round questionnaire survey was carried out among 32 experts nationwide using the Delphi method,and then the concentration and coordination of the experts'opinions on each of the alternative items were analyzed.In the third round of the survey,all of diagnostic indicators were classified into primary or secondary symptoms according to the weighting coefficients of each item,and then the judgment condition options for the diagnostic criteria of the symptoms were formed.Through the fourth-round of expert survey,the diagnostic mode and diagnostic conditions of spleen deficiency with dampness accumulation syndrome were clarified.Results The alternative diagnostic indicators were screened according to the concentration degree and the variation coefficient of experts'opinions,and 24 diagnostic indicators were obtained after merging the similar indicators,of which there were three primary symptoms(poor appetite and anorexia,loose stool,and pale and swollen tongue with tooth marks)and 21 secondary symptoms(abdominal distension,tastelessness in the mouth without thirst,obesity,drowsiness,fatigue and lack of strength,thready and smooth pulse,soft pulse,undigested food in the stool,and light-red skin lesions,etc.).The fourth-round expert survey confirmed that the necessary conditions for the diagnosis of psoriasis vulgaris of spleen deficiency with dampness accumulation syndrome were"the disease-location of the spleen","the disease-nature of qi deficiency"and"the disease-nature of dampness";the diagnostic criteria for psoriasis of spleen deficiency with dampness accumulation syndrome were as follows:(1)with three primary symptoms;(2)with two primary symptoms and any two of the secondary symptoms.Conclusion The diagnostic criteria for psoriasis vulgaris of spleen deficiency with dampness accumulation syndrome constructed in this study include both primary and secondary symptoms,with clarified conditions and being easy to be practiced clinically,and have good clinical credibility.

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 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 This study aims to elucidate the mechanism of action of Isoliquiritigenin(ILG)in the treatment of Dia-betic Encephalopathy(DE)based on network pharmacological analysis and in-vitro experiments.METHODS The potential targets of ILG were predicted using the HERB database and SwissTargetPrediction database.DE-associated disease targets were obtained from GeneCards,OMIM,and PharmGkb,and the intersecting targets between ILG and DE were identified using the Venny software.A PPI network was constructed using the STRING database,and core targets were screened out using Cytoscape software.GO function and KEGG pathway enrichment analyses were undertaken using R 4.0.3,followed by validation via molecular docking techniques and in vitro experiments.RESULTS 65 intersecting targets between ILG and DE were identified in this study.Topological analysis yielded eight core targets namely,EGFR,ESR1,PTGS2,PPARG,GSK3β,CDK2,PIK3R1,and F3.GO function and KEGG pathway en-richment analyses revealed that ILG antagonizes DE through several biological processes which impact numerous cellular components and molecular functions such as response to lipopolysaccharides,protein phosphorylation,protein kinase activity,and serine/threo-nine/tyrosine kinase activity.Pathways implicated included the PI3K-Akt signaling pathway,protein polysaccharide signaling pathway in cancer,and endocrine resistance pathway.The molecular docking results showed that all eight core targets had a good binding with ILG,especially with GSK3β,with a binding energy of-7.22 kcal·mol-1.In vitro experiments indicated that ILG could improve high glucose-induced cell damage and activate the PI3K/AKT/GSK3β signaling pathway.CONCLUSION ILG is likely to exert its effects on GSK3β to regulate the PI3K/AKT/GSK3β signaling pathway,thereby alleviating DE.

The present study investigated the mechanism of total flavonoids from Ampelopsis grossedentata(AGTF) against gouty arthritis(GA) by network pharmacology and experimental validation. The main active ingredients and targets of AGTF, as well as disease targets, were screened out using relevant databases and literature data. The "protein-protein interaction"(PPI) network and "drug-ingredient-target-pathway" network were constructed, and the potential targets and mechanism of AGTF against GA were predicted. The hyperuricemia(HUA) combined with GA model was induced in rats. The gait behaviors of rats were scored, and ankle swelling degree was observed. The uric acid(UA) level and xanthine oxidase(XOD) activity in the rat serum were detected, and the levels of interleukin-1β(IL-1β), interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α) were measured. The protein expression of toll-like receptor 4(TLR4), myeloid differentiation factor 88(MyD88), and nuclear factor-kappa B(NF-κB) in the synovial tissues of the rat ankle joint was determined by immunohistochemistry. Ten active ingredients of AGTF and 73 candidate targets of AGTF against GA were screened out by network pharmacology. Eighty-six signaling pathways were enriched, including TNF signaling pathway, NF-κB signaling pathway, TLR signaling pathway, Nod-like receptor signaling pathway, and purine metabolism signaling pathway, which were closely related to AGTF against GA. Animal experimental results showed that AGTF could effectively improve the abnormal gait behaviors of GA rats, relieve ankle inflammation, and reduce ankle joint swelling. In addition, AGTF could significantly reduce UA level, inhibit XOD activity, decrease TNF-α, IL-6, and IL-1β content, and down-regulate the expression of TLR4, MyD88, and NF-κB in ankle synovial tissues(P<0.05, P<0.01). The results of network pharmacology and experimental validation are consistent, indicating that AGTF exerts its therapeutic effect on GA by regulating UA metabolism, improving abnormal UA level, reducing the release of inflammatory factors, and regulating immunity and the TLR4/MyD88/NF-κB inflammatory pathway.

Objective: To investigate the prevalence and Influence factors of work-related musculoskeletal disorders (WMSDs) among dental nurses in tertiary stomatology hospitals. Methods: From June to July 2020, 1321 dental nurses from 18 tertiary stomatology hospitals in 18 provinces of China were enrolled as research subjects through a phased sampling method. The cross-sectional study was performed with validated instruments including the basic information questionnaire, Effort-Reward Imbalance Questionnaire, Nurse-Physician Collaboration Scale, and Chinese Musculoskeletal Questionnaire, so as to get the information about the social demography information, nursing-physician cooperation, work stress and the incidence of WMSDs. The influenang factors of WMSDs was analyzed. Results: The past prevalence, annual prevalence, and weekly prevalence of WMSDs were 80.8% (1067/1321) , 68.7% and 43.7% (575/1321) . 58.4% (771/1321) of nurses had WMSDs in three or more body parts. Neck (51.4%) , waist (42.2%) and shoulder (41.6%) were the top three body regions in the past year. The absenteeism rate due to musculoskeletal disorders ranged from 3.5% to 9.0%, waist (8.9%) and neck (8.0%) were the top two body regions. Working more than 40 hours per week (OR=1.74, P<0.001) and effect/reward>1 (OR=1.50, P=0.002) were risk factors of WMSDs (OR=1.74, 95% CI: 1.32~2.30; OR=1.50, 95%CI: 1.17~1.92, P<0.05) , while regular physical exercise every week (≥30 min per times) was the protective factor (OR=0.74, 95%CI: 0.56~0.97, P=0.030) . Conclusion: The prevalence rate of WMSDs of dental nurses in China was high, and most of the nurses suffered with many body parts. Thus, we should reduce controllable occupational stresso, ensuring adequate rest and strengthening physical exercise to reduce the incidence of WMSDs.

Chronic kidney disease (CKD) is a progressive disease with many complications (eg, cardiovascular disease and acidosis and anemia) and high morbidity and mortality occurs in the population. There is no cure for this disease, current treatments including renin-angiotensin-aldosterone pathway inhibitors and sodium-glucose co-transporter 2 inhibitors can only delay the progression to end-stage renal disease. With the identification of more key factors and mechanisms in CKD development, new potential therapeutic approaches for CKD can be developed. This review summarizes the mainstays of therapy and strategies for CKD and related comorbidities to support the development of novel treatments.

Toxicity-attenuating compatibility is an effective measure to ensure the safety of Chinese medicine. Involving the origin, processing method, compatibility mode, and dosage, it faces multiple challenges, such as the uncertainty of toxic substances, toxicity latency, indefinite safe dose, complex toxicity-efficacy relationship, and individual difference. As a result, research on clinical safety of Chinese medicine is limited by the consistency at "molecular-cellular-organ-overall" levels, unclear interaction of multiple medicinals and multiple substances, the "toxicity-efficacy-compatibility-syndrome" correlation, and the "dosage-time-toxicity-efficacy" conversion law. Therefore, following the principle of "starting from the clinical practice, verifying via the theoretical basis, and finally applying in clinical practice", we verified the toxicity at "molecular-cellular-organ-overall" levels, revealed the interaction of multiple medicinals and substances, collected evidence at multiple levels, clarified the "dosage-time-toxicity-efficacy" relationship, and tested the consistency between basic and clinical biomarkers. On this basis, we studied the toxicity-alleviating and efficacy-enhancing(preserving) compatibility characteristics, the fate of one medicinal and multiple medicinals in vivo, the molecular mechanism of toxicity, the "dosage-time-toxicity-efficacy" conversion law, and the clinical characteristics of toxic traditional Chinese medicine based on disease and syndrome. The three mechanisms of toxicity-attenuating compatibility reflect the seven-reaction theory in Chinese medicine compatibility. Finally, the strategies for safe use of Chinese medicine were proposed.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.
