Objective:To investigate the clinicopathological features, diagnosis and differential diagnosis of pseudocarcinomatous hyperplasia of the fallopian tubes.Methods:Sixteen cases of pseudocarcinomatous hyperplasia of the fallopian tubes diagnosed at Obstetrics and Gynecology Hospital of Fudan University from January 2011 to January 2024 were collected.The pathological sections were reviewed, the clinical and pathological data were consulted, and immunohistochemical examination was conducted along with follow-up.Results:The patients were aged from 19 to 57 years, with an average age of 41 and a median age of 38. Among the 16 cases, 4 were located in the right fallopian tubes, 6 in the left fallopian tubes, while the remaining cases presented bilaterally. The general manifestations were tubal edema, crispness and purulent secretion in the lumen. Morphologically, the fallopian tube mucosa exhibited a significant infiltration of neutrophils, lymphocytes and plasma cells. The epithelial cells of the fallopian tube displayed evident proliferation, stratification and disorganized arrangement leading to formation of small glandular cavity with back-to-back, fissure-like and sieve-like structures. Immunohistochemical analysis revealed positivity for CK7 and WT1, along with wild-type p53 expression, Ki-67 index ranged from 5% to 20%. During the follow-up period ranging from 1 to 156 months, all the patients remained free of disease.Conclusions:Pseudocarcinomatous hyperplasia of the fallopian tube is a rare non-neoplastic lesion, which can lead to epithelial hyperplasia and atypical hyperplasia. The most important significance of recognizing this lesion lies in avoiding misdiagnosis of fallopian tube cancer during intraoperative and postoperative pathological examination. This ensures that clinicians can administer correct clinical interventions.

Objective To explore the mechanism by which puerarin alleviates the cardiotoxicity induced by doxorubicin in myocardial cells. Methods Cells in the logarithmic growth phase were divided into normal control group,model group,low-(20 mmol·L-1),medium-(40 mmol·L-1) and high-(80 mmol·L-1) dose puerarin groups,and positive control group(captopril,1 mmol·L-1). Except for the normal control group,the other groups were co-incubated with 5 mmol·L-1 doxorubicin. Cell viability was assessed using CCK-8 and lactate dehydrogenase (LDH) assays. ROS levels were detected using a ROS probe. Autophagy flux was detected by transfection with HBAD-mcherry-EGFP-LC3 adenovirus. Western Blot was used to measure the protein expression levels of Beclin-1,LC3,p62,p-AMPKα,and AMPKα. Lysosomal function was assessed using a lysosomal probe. Immunofluorescence was used to detect the relative intensity and co-localization of ASMase and LAMP1. Molecular docking analysis was performed to predict the binding capacity of PUE with ASMase. Differential gene expression was analyzed by gene set enrichment analysis. Results Compared to the normal control group,the model group showed reduced cell viability (P<0.01),increased release levels of LDH and ROS (P<0.05,P<0.01),increased number of autophagosomes (P<0.01),and decreased number of autophagic lysosomes (P<0.05). Beclin-1 protein expression and LC3-II/LC3-I ratio decreased(P<0.01),but p62 protein expression increased(P<0.01). Fluorescence intensity of lysosome decreased(P<0.01),whereas fluorescence intensity of ASMase increased(P<0.01). Immunofluorescence co-localization of ASMase and LAMP1 increased (P<0.01),the ratio of p-AMPKα/AMPKα decreased(P<0.05). Compared to the model group,the high-dose puerarin group showed a rebound in cell viability (P<0.05). The medium-and high-dose puerarin groups showed a decreasing trend in LDH level (P<0.05),and all puerarin groups showed a decreasing trend in ROS level (P<0.01). The number of autophagosomes in high-dose puerarin group reduced (P<0.01). The number of autophagic lysosomes in all puerarin groups increased (P<0.05,P<0.01). The high-dose puerarin group showed increased expression of Beclin-1 (P<0.05) and LC3-II/LC3-I ratio,and decreased p62 expression (P<0.01). All puerarin groups showed increased lysosomal fluorescence intensity (P<0.05,P<0.01). The medium-and high-dose puerarin groups showed a decrease in ASMase fluorescence intensity(P<0.05),a reduction in the immunofluorescence co-localization of ASMase with LAMP1 (P<0.01),and an increase in the p-AMPKα/AMPKα ratio (P<0.01). Molecular docking analysis discovered puerarin showed a binding energy of-8.6 kcal·mol-1 with ASMase. Gene enrichment analysis indicated that the differentially expressed genes in the doxorubicin cardiotoxicity model were related to apoptosis,autophagy,and lysosomal function. Conclusion Puerarin can alleviate doxorubicin-induced cardiotoxicity in myocardial cells and protect myocardial cells by regulating autophagy through AMPK/ASMase,as well as restoring autophagic flux.

Reperfusion injury occurs after return of spontaneous circulation (ROSC) in patients with cardiac arrest (CA), which leads to multiple organ dysfunction, called post-cardiac arrest syndrome (PCAS). PCAS is closely related to the prognosis of CA patients, and is an independent risk factor of survival. Integrated traditional Chinese and Western medicine diagnosis and treatment is critical for improving prognosis of PCAS. In order to guide and standardize integrated traditional Chinese and Western medicine diagnosis and treatment in PCAS among clinicians, nurses and research personnel in China, the Emergency Medicine Professional Committee of the Chinese Society of Integrated Chinese and Western Medicine has established an expert group to determine 14 clinical issues related to the diagnosis and treatment of PCAS with integrated traditional Chinese and Western medicine through clinical survey. The working group formulates a search strategy for each clinical issue according to the PICO principle. Chinese and English literature were searched from CNKI, Wanfang, VIP, SinoMed, PubMed, Embase, and Cochrane Library. The grade of recommendations assessment, development and evaluation (GRADE) were used to form the level of evidence and recommendation. When the literature evidence was insufficient, the recommendations and level of recommendation were formed after expert discussion. Combined with the aspects of generalizability, suitability, and resource utilization, the expert consensus developed 28 recommendations around the 14 aspects of three stages of PCAS, including early circulation, respiratory support and reversible cause relief, mid-term neuroprotection, improvement of coagulation, prevention and treatment of infection, kidney and gastrointestinal protection and blood sugar control, post rehabilitation treatment, providing references for the integrated traditional Chinese and Western medicine of the diagnosis and treatment for PCAS.

As a common psychiatric disorder, the etiology and pathogenesis of depression are complex and not yet fully elucidated.The diagnosis of depression mainly depends on the patients’ medical history, clinical symptoms and related examinations.Identification of biomarkers will provide important clues for the specific diagnosis and targeted treatment of depression.In addition to the widely recognized neurotransmitter dysregulation, hypothalamus-pituitary-adrenal axis hyperactivity, neuroplasticity, and neuro-inflammation theory, oxidative stress is also involved in the pathogenesis of depression in multiple ways.Many studies showed that the heat shock protein 70(HSP70)levels will increase in early stage to cope with the stress in patients with depression.However, lower HSP70 levels are often correlated with more severe depressive symptoms.HSP70 may be involved in depression through multiple pathways of oxidative stress, glucocorticoid receptors, neuroinflammation and neuroplasticity.Furthermore, increasing HSP70 expression results in significant improvement in depression-like behavior in animals.Thus, HSP70 possesses potential value as an early warning marker for depression as well as a therapeutic target.

Since the implementation of the Measures for the Management of Radiation Workers’ Occupational Health in November 2007, it has played an extremely important role in protecting the occupational health of radiation workers. There are more than 700 000 radiation workers in about 100 000 workplaces with potential radiation exposure, as well as a large number of miners exposed to high levels of radon. As the radiation health monitoring project suggests, measures of occupational health management such as personal dose monitoring and occupational health examination of radiation workers have been widely implemented and achieved good results in the protection of radiation workers. However, the risks of chromosomal aberration and specific turbidity of the eye lens of radiation workers have increased in high-risk positions such as interventional radiology, nuclear medicine, and industrial flaw detection. The control of high radon exposure in miners needs to be strengthened. It is necessary to adapt to the new situation in view of new challenges and actively promote the revision of the Measures for the Management of Radiation Workers’ Occupational Health, so as to further improve the occupational health management of radiation workers in China.

OBJECTIVE: To screen for differentially expressed circular RNAs (circRNAs) in the serum of preterm infants with intraventricular hemorrhage (IVH) and explore the competitive endogenous RNA (ceRNA) mechanism of circRNAs in IVH in these infants. METHODS: Fifty preterm infants (gestational age of 28 to 34 weeks) admitted in our department between January, 2019 and January, 2020 were enrolled in this study, including 25 with a MRI diagnosis of IVH and 25 without IVH. Serum samples were collected from 3 randomly selected infants from each group for profiling differentially expressed circRNAs using circRNA array technique. Gene ontology (GO) and pathway analyses were performed to reveal the function of the identified circRNAs. The circRNA-miRNA-mRNA network was constructed to identify the co-expression network of hsa_circ_ 0087893. RESULTS: A total of 121 differentially expressed circRNAs were identified in the infants with IVH, including 62 up-regulated and 59 down-regulated circRNAs. GO and pathway analyses showed that these circRNAs were involved in multiple biological processes and pathways, including cell proliferation, activation and death, DNA damage and repair, retinol metabolism, sphingolipid metabolism, cell adhesion molecules. Among these circRNAs, hsa_circ_0087893 was found to have significant down-regulation in IVH group and co-express with 41 miRNAs and 15 mRNAs (such as miR-214-3p, miR-761, miR-183-5p, AKR1B1, KRT34, PPP2CB, and HPRT1). CONCLUSION The circRNA hsa_circ_0087893 may function as a ceRNA and play an important role in the occurrence and progression of IVH in preterm infants.

OBJECTIVE To establish the met hod for the purific ation of test sample of Banxialu granules ，and to determine the contents of 4 ephedrine components such as ephedrine ，pseudoephedrine，norpseudoephedrine and methylephedrine. METHODS Three batches of Banxialu granules were extracted with methanol（containing 1％formic acid ）and pretreated with QuEChERS method of N-propyl ethylenediamine adsorbent （PSA）and octadecyl bonded silica gel adsorbent （C18）. Ultra high performance liquid chromatography tandem triple quadrupole mass spectrometry （UHPLC-MS/MS）was adopted. The separation was performed on an Agilent XDB-C 18 column with 5 mmol/L ammonium acetate solution （containing 0.1％ formic acid ）-acetonitrile as mobile phase（gradient elution ）at the flow rate of 0.40 mL/min. The column temperature was set at 30 ℃，and sample size was 2 μL. The electrospray ionization source was adopted ，and positive ion scanning was performed in multiple reaction monitoring mode. The ion pairs used for quantitative analysis were m/z 166.2→148.1（ephedrine，pseudoephedrine），m/z 152.2→134.1（norpseudoephedrine）， m/z 180.2→162.2（methylephedrine）. RESULTS The solution obtained by QuEChERS purification method was clear and nearly colorless. The linear ranges of ephedrine ， pseudoephedrine， norpseudoephedrine and methylephedrine were 1.38-206.82， 1.41-212.13，1.29-19.34，1.99-59.83 ng/mL（r＞0.99）. The limits of detection were 0.41，0.42，0.39 and 0.60 ng/mL. The limits of quantitation were 1.38 ，1.41 ，1.29 and 1.99 ng/mL，respectively. RSDs of precision ，stability（48 h）and repeatability tests were all lower than 2％. The average recoveries were 95.75％-100.87％（RSD＜2％，n＝9）. The contents of above 4 ephedrine components were 20.62-26.02，20.96-24.90，2.26-2.63，5.36-6.32 μg/g， respectively. CONCLUSIONS Established method is simple ，rapid，sensitive and suitable for simultaneous determination of 4 ephedrine components in Banxialu granules.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.

Purpose: The present study investigated the association between Systematic COronary Risk Evaluation (SCORE)-estimated cardiovascular risk and carotid stiffening in a middle-aged population using ultrafast pulse wave velocity (ufPWV). Methods: This study enrolled 683 participants without known cardiovascular disease or diabetes mellitus who underwent ufPWV measurements. Clinical interviews, physical examinations, laboratory findings, carotid intima-media thickness (cIMT), pulse wave velocity (PWV) at the beginning of systole (PWV-BS), and PWV at the end of systole (PWV-ES) were assessed. Each participant underwent an assessment of SCORE risk based on major cardiovascular risk factors (CVRFs), including age, sex, smoking, systolic blood pressure (SBP), and total cholesterol (TC). Crude and adjusted odds ratios (ORs) with 95% confidence intervals and ordinal logistic regression were used. Overall CVRFs were adjusted to assess ORs. Results: cIMT and carotid stiffening in PWV-BS and PWV-ES were significantly different between sex subgroups (all P<0.05), but only PWV-ES increased gradually in age and SCORE-estimated risk subgroups (all P<0.05). Compared with cIMT (r=0.388, P<0.001) and PWV-BS (r=0.159, P<0.001), PWV-ES was more strongly correlated with SCORE categories (r=0.405, P<0.001). Higher PWV-ES values were associated with SCORE categories independently of sex, SBP, TC, and smoking in moderate-risk and high-risk subgroups (OR, 1.63; P<0.001 and OR, 2.12; P=0.024, respectively), but were not independent of age in all risk subgroups (all P>0.05). Conclusion Carotid stiffening quantified by ufPWV is linked to SCORE categories, and elevated PWV-ES may aid in cardiovascular risk stratification.
