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 investigate the distribution characteristics of urinary tract pathogens in patients with community-acquired urinary tract infection and their sensitivity to nenoxacin and levofloxacin.Methods:This prospective, multicenter clinical trial included patients with community-acquired urinary tract infection who were admitted to urological clinics at 9 clinical research centers from November 2021 to August 2022.Inclusion criteria: Patients aged 18-70 years with community-acquired acute uncomplicated cystitis(AUC), recurrent acute episodes of urinary tract infection(rUTI), and non-febrile complicated urinary tract infection(cUTI) with signs of urinary tract irritation and abnormal elevation of routine white blood cells in urine. Exclusion criteria: ①Patients who received effective antimicrobial therapy within 72 h before enrollment and lasted for more than 24 h. ②Fever (>37.3℃) or symptoms of upper urinary tract infection such as low back pain, tapping pain in the kidney area, etc. ③Indwelling urinary catheter. At the first visit, clean midstream urine samples were taken for bacterial culture, and the distribution characteristics of urinary pathogens of different types of urinary tract infections were analyzed. Extended spectrum β-lactamases (ESBLs) were measured for Gram-negative bacteria. The susceptibility of nenoxacin and levofloxacin to urinary tract pathogens was determined by disk diffusion method. Drug resistance rate, sensitivity rate were analyzed between different disease groups.Results:There were 404 enrolled patients from 9 hospitals, including 364 (90.1%) females and 40 (9.9%) males. A total of 177 strains of pathogenic bacteria were isolated, among which the highest proportion of Escherichia coli was 66.1% (117/177).Klebsiella pneumoniae was followed by 6.8% (12/177) and Streptococcus agalactis 5.1% (9/177). The bacterial spectrum distribution of AUC and rUTI were similar, and the proportions of Escherichia coli were 70.6% (85/119) and 65.9% (29/44), respectively. However, the proportions of Escherichia coli isolated from cUTI patients were only 28.6% (4/14) and Enterococcus faecalis 7.1%(1/14). The overall detection rate of ESBLs in Gram-negative bacteria was 30.9%(43/139). The sensitivity rate of nenoxacin was 74.6%(91/122), and the resistance rate was 25.4%(31/122). The overall sensitivity rate of levofloxacin was 44.9%(70/156) and the resistance rate was 36.5%(57/156). The rate of resistance of urinary tract pathogens to levofloxacin was 48.2% (27/56) in patients with previous urinary tract infection history, and 30.0% (30/100) in patients with no previous urinary tract infection history, the difference was statistically significant( P=0.023).The sensitivity rate of Gram-negative bacteria to nenofloxacin was 70.7% (65/92) and that to levofloxacin was 50.0% (46/92, P<0.001). The sensitivity of Gram-positive bacteria to nenofloxacin was 80.0% (16/20), and that to levofloxacin was 70.0% (14/20, P=0.009). Conclusions:The bacterial profile of out-patient community acquired urinary tract infection varies greatly according to different diseases. The proportion of Escherichia coli in AUC and rUTI patients is higher than that in cUTI. The detection rate of ESBLs in Gram-negative bacteria was lower than the domestic average.Patients with a history of urinary tract infection had a high risk of treatment failure with levofloxacin. The sensitivity of common urinary tract pathogens to nenofloxacin was higher than levofloxacin.

In this study, the mechanism of Xiaoyan Lidan formula (XYLDF) against 3,5-diethoxycarbonyl-1,4-dihydro-2,4,6-collidine (DDC)-induced chronic intrahepatic cholestasis (CIHC) in mice was investigated based on metabolomics, molecular docking and pharmacological methods. In the pharmacodynamics study, a dosage of 5 g·kg^-1 (clinical equivalent) XYLDF was administered in DDC-induced mice, then the effect of XYLDF against CIHC was evaluated by measuring the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (AKP) as well as total bilirubin (TBIL) in serum and observing liver histopathological changes. All experiments were approved by the Ethical Committee Experimental Animal Center of Guangzhou University of Chinese Medicine (ZYD-2021-001). The serum metabolites of mice in each group were detected and identified based on ultra-performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry, and the relevant biological pathways and molecular key targets were further enriched. Molecular docking technology was used to further evaluate the binding activity of the main active ingredients of XYLDF with potential targets. Subsequently, the in vitro experiment was conducted for the validation of the vital target. The results showed that compared with the model group, XYLDF significantly decreased the levels of ALT, AST, AKP and TBIL in the serum of CIHC mice, as well as alleviated inflammatory infiltration and hepatocyte necrosis in liver tissue. According to the metabonomic study, a total of 35 differential metabolites was identified as biomarkers associated with cholestasis, 12 of which were significantly recovered by XYLDF treatment. These biomarkers were involved in the pathways of primary bile acid biosynthesis and linoleic metabolism, which are closely related to the mechanism of XYLDF against CIHC. Protein-protein interaction network indicated that cytochrome P450 3A4 (CYP3A4) and cytochrome P450 1A1 (CYP1A1) are significant potential targets with good binding properties with six major active ingredients of XYLDF. Furthermore, it was found that 4-methoxy-5-hydroxycanthin-6-one, dehydroandrographolide and isodocarpin, three of the main active components in XYLDF, markedly induced the expression of CYP3A4 mRNA in vitro. This study revealed that XYLDF mainly mediates the biosynthesis of bile acids in CIHC mice to improve liver tissue lesions and bile efflux disorders, among which, CYP3A4 is the key target in the protection of XYLDF against CIHC. This research provides a reference for further elucidation of the pharmacological mechanism of XYLDF.

BACKGROUND: Abnormal type I collagen (COL1) expression is associated with the development of many cardiovascular diseases. The TGF-beta/Smad signaling pathway and circRNAs have been shown to regulate COL1 gene expression, but the underlying molecular mechanisms are still not fully understood. METHODS: Gain- and loss-of-function experiments were prformed to study the effect of circZBTB46 on the expression of alpha 2 chain of type I collagen (COL1A2). Co-immunoprecipitation assay was performed to observe the interaction between two proteins. RNA immunoprecipitation assay and biotin pull-down assay were performed to observe the interaction of circZBTB46 with PDLIM5. RESULTS: In this study, we investigated the role of circZBTB46 in regulating COL1A2 expression in human vascular smooth muscle cells (VSMCs). We found that circZBTB46 is expressed in VSMCs and that TGF-beta inhibits circZBTB46 formation by downregulating KLF4 expression through activation of the Smad signaling pathway. CircZBTB46 inhibits the expression of COL1A2 induced by TGF-beta. Mechanistically, circZBTB46 mediates the interaction between Smad2 and PDLIM5, resulting in the inhibition of Smad signaling and the subsequent downregulation of COL1A2 expression. Furthermore, we found that the expression of TGF-beta and COL1A2 is decreased, while circZBTB46 expression is increased in human abdominal aortic aneurysm tissues, indicating that circZBTB46-mediated regulation of TGF-beta/Smad signaling and COL1A2 synthesis in VSMCs plays a crucial role in vascular homeostasis and aneurysm development. CONCLUSIONS CircZBTB46 was identified as a novel inhibitor of COL1 synthesis in VSMCs, highlighting the importance of circZBTB46 and PDLIM5 in regulating TGF-beta/Smad signaling and COL1A2 expression.

Objective: To investigate the chronic respiratory symptoms and pulmonary function of adult residents in 3 towns of Hongtong County, Shanxi Province, and to explore their risk factors. Methods: The investigation of chronic respiratory symptoms and lung function status of adult residents in Hongdong County is based on the regional population of the entire county in Hongdong County. The project was initiated by the Science and Technology Department of Linfen City and coordinated by the Hongdong County Government. The investigation will be conducted in 3 townships in Hongdong County, Linfen City, Shanxi Province from April to November 2021: Demographic characteristics, respiratory symptoms, smoking dust exposure and other personal history were collected through questionnaires. Physical examination, routine blood tests and lung function tests were also performed on each individual. SPSS 22.0 software was used to conduct t test, χ² test, ANOVA or Kruskal-Wallis test for statistical analysis of the collected information. Results: 10 945 subjects aged 18-102 years were included in the analysis, of whom 3 754 (34.3%) were male, 1 222 (11.2%) had a history of dust exposure, 7 164 (65.5%) had used straw and firewood as cooking fuel, and 3 296 (30.1%) had a history of smoking. Among the participants, 394 (3.6%), 339 (3.1%), and 1 543 (14.1%) had respiratory symptoms such as chronic cough, sputum, and dyspnea. Statistics showed that the population with chronic respiratory symptoms was more elderly and had a smoking history, and the incidence of chronic respiratory symptoms was higher in those who smoked more than 40 packs a year (all P<0.05). Men with a history of dust exposure were more likely to suffer from chronic cough and expectoration, while emaciation and biofuel use for more than 40 years were more likely to suffer from chronic expectoration and dyspnea (all P<0.05). The median values of forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC) and FEV1/FVC in 1 second were 2.19 L/s, 3.24 L and 69.16%, respectively. Among them, the lung function of 5 801 (53.0%) respondents was lower than the expected value. The median FEV1/FVC decreased with the increase of age. The FEV1/FVC of people over 40 years old with smoking history was lower, the dust exposure history of people with decreased lung function was more than that of people with normal lung function, and the incidence of chronic expectoration and dyspnea was higher in people with decreased lung function (all P<0.05). The absolute value and ratio of eosinophils in patients with decreased ventilation function over 60 years old were significantly higher than those with normal ventilation function, but the level of body mass index (BMI) was lower (all P<0.05). Conclusion: In Hongdong County, Shanxi Province, grassroots residents have poor medical awareness, low lung function examination rate, chronic respiratory symptoms and lung function decline are associated with more risk factors. Primary medical institutions need to formulate prevention strategies and carry out lung function detection according to the actual situation, focusing on monitoring and follow-up of high-risk groups to achieve early and timely prevention, diagnosis and treatment of chronic obstructive pulmonary disease.

OBJECTIVE: To develop a new classification of acromion based on the subacromial impingement theory and the Rockwood tilt view. And explore the application value of the new classification in the diagnosis and treatment of rotator cuff tear. METHODS: The clinical data of 101 patients underwent shoulder arthroscopic surgery for impingement syndrome or rotator cuff tear from January to December 2017 were retrospectively analyzed. There were 34 males and 67 females, aged from 34 to 76 years with an average of (56.31±9.63) years old, course of disease from 2 to 12 months with average of 6 months. Preoperative radiographs of the routine anteroposterior view, Rockwood tilt view and the supraspinatus outlet view were obtained. Based on the subacromial impingement theory and Rockwood radiographs, the morphology of the acromion can be divided into three types:typeⅠ(flat type), typeⅡ(bump type), and type Ⅲ (impingement type). Two observers classified 101 shoulder Rockwood radiographs according to the new classification method and the supraspinatus Outlet radiographs according to the traditional acromial morphological classification method. Supraspinatus tendon injuries were classified into no tear, partial-thickness tear, and full-thickness tear according to the arthroscopic findings. Concordance test (Kappa value) between the inter-observer and intra-observer was carried out for the new classification method and the traditional classification method respectively. The rank sum test was used to compare the mean acromiohumeral distance(AHD) of the three acromion forms in the new acromion classification method. Spearman rank correlation test and Gamma method were used to analyze the correlation between the new acromion classification method and the degree of supraspinatus tendon tear. RESULTS: The inter-observer consistency analysis of the new classification system was significantly better than that of the traditional classification (0.827 vs 0.278), the intra-observer consistency analysis of the new classification system were also significantly better than that of the traditional classification (0.921 vs 0.448, 0.890 vs 0.539). There was no statistical significance in the AHD among three types of the new classification(H=2.186, P>0.05). In all 101 patients, the highest proportion of impingement type acromion was 45.5% (46 cases), followed by bump type acromion was 36.6% (37 cases), and flat type acromion was 17.8% (18 cases). The incidence of supraspinatus tendon tear in the patients with impingement type acromion was significantly higher than that of the other two types of acromion, there was a spearman rank correlation between the new acromion type and the degree of the supraspinatus tendon tear(rs=0.719, P<0.001). CONCLUSION Rockwood radiographs of the shoulder can well display the anterolateral osteophytes of the acromion. The new acromion classification method based on Rockwood radiographs has high reliability and good reproducibility, in which impingement type of acromion is closely related to supraspinatus tendon tear. Compared with the traditional classification and AHD, the new classification method has more diagnostic value than for rotator cuff injury.
