In February 2025, a local cluster outbreak caused by the D8 genotype Measles virus (MV) was first discovered in Henan Province. Epidemiological investigations and laboratory testing were conducted, including the collection of serum and throat swabs for MV IgM antibody and nucleic acid detection, virus isolation and genetic homology analysis. Measures such as close contact tracing, vaccination rate assessment and supplementary immunization activities were implemented, successfully preventing broader community transmission. A total of three cases were reported during the outbreak, including one imported-related adolescent and two secondary local adult cases. All cases presented with typical symptoms such as fever and rash. Both adult cases were complicated by pneumonia, with one case developing into severe pneumonia. MV genotyping showed that the two secondary cases were both the D8 genotype, with the viral sequences being completely homologous to the Kazakhstan strain. Among the close contacts, 98.2% were adults, and 142 individuals received emergency vaccination.

Objective:To analyze the changes in the retinal and choroidal microvascular structures in the macular region of patients with acute central serous chorioretinopathy (CSC), as well as the influencing factors of subretinal fluid (SRF) volume.Methods:A prospective selection of 37 patients with monocular acute CSC diagnosed by ophthalmology examination at the Xi ′an First Hospital from January to October 2023 was conducted. The affected eye group was Group A, and the contralateral eye was Group B. The right eye of 30 age and gender matched normal individuals during the same period was selected as the normal eye group (group C). The scanning frequency source optical coherence tomography (SS-OCTA) was used to scan the macular area of the tested eye within a range of 6 mm×6 mm. We analyzed and recorded the vascular density (VD), perfusion area (PA), retinal thickness (RT), choroidal thickness (CT), as well as choroidal vascular volume (CVV) and choroidal vascular index (CVI) of the superficial and deep retinal capillary plexus (SCP) and deep retinal capillary plexus (DCP) in the macular area of 0-1 mm, 0-3 mm, and 0-6 mm using our own software. At the same time, we recorded the volume of SRF in the affected eye group. We compared the changes in VD, PA, RT, CT, CVV, and CVI among three groups. The Spearman rank correlation test was used to analyze the correlation between SRF volume and microvascular structural parameters.Results:(1) There was no statistically significant difference in VD and PA of SCP between the affected eye group and the contralateral eye group within the range of 0-6 mm in the macular area (all P>0.05); The VD and PA of SCP in the affected eye group and the contralateral eye group were lower than those in the normal eye group, and the differences were statistically significant (all P<0.05); The VD and PA of DCP in the affected eye group were lower than those in the contralateral eye group, and the difference was statistically significant (all P<0.05). Within the range of 0-3 mm in the macular area, the VD and PA of DCP in the affected eye group and the contralateral eye group were lower than those in the normal eye group, and the differences were statistically significant (all P<0.05). The RT of the affected eye group was higher than that of the contralateral eye group, and the RT of the contralateral eye group was higher than that of the normal eye group, with statistical significance (all P<0.05). (2) Within the range of 0-6 mm in the macular area, the CT of the affected eye group was higher than that of the contralateral eye group, and the CT of the contralateral eye group was higher than that of the normal eye group, with statistical significance (all P<0.05). There was no statistically significant difference in the CVV and CVI of the choroidal vessels between the affected eye group and the contralateral eye group (all P>0.05); The CVV and CVI of the choroidal vessels in the affected eye group and the contralateral eye group were higher than those in the normal eye group, and the differences were statistically significant (all P<0.05). (3) The volume of SRF is negatively correlated with the VD of DCP within the range of 0-3 mm in the macular area ( P<0.05), and positively correlated with CT within the range of 0-6 mm ( P<0.05). Conclusions:Acute CSC is a binocular choroidal disease, and choroidal thickening is mainly due to the thickening of the large and medium vascular layers; Acute CSC can cause a decrease in superficial and deep retinal blood flow density in the macular region; The volume of SRF is negatively correlated with the VD of DCP and positively correlated with CT.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective : To identify the main components in the extracts of different parts of Juandan Baihe (Lilium lancifolium) by ultra-high performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) technology and investigate their hypoglycemic activities. Methods: The MS fragmentation pathways of the main types of compounds in Juandan Baihe (Lilium lancifolium) were studied, and the main components in the extracts were systematically identified using MS fragmentation pathways combined with MS mining technology. Based on the hyperglycemia male mouse model [specific pathogen free (SPF)-grade Kunming mice] induced by streptozotocin (intragastric administration of 80 mg/kg for 3 d), the hypoglycemic effects of extracts of Juandan Baihe (Lilium lancifolium) roots, stems, corms, leaves, and flowers were evaluated by measuring the changes of blood glucose, daily water consumption, daily food intake, and body weight. Result: The MS fragmentation pathways of regalosides, dioscins, phenylpropanoids, flavonoids, and chlorogenic acids in Juandan Baihe (Lilium lancifolium) were clarified, and a mining method for compounds in this plant was constructed. A total of 58 compounds, including 6 chlorogenic acids, 14 regalosides, 13 phenylpropanoids, 5 flavonoids, and 20 dioscins, were identified from the roots, stems, corms, leaves, and flowers of Juandan Baihe (Lilium lancifolium). Among them, 30 compounds were reported for the first time from this plant. The root and corm extracts demonstrated significant hypoglycemic activities by reducing blood glucose levels from 23.76 ± 1.21 and 24.29 ± 1.35 mmol/L to 17.21 ± 1.23 and 18.78 ± 1.49 mmol/L, respectively (P < 0.05). The roots and corms extracts could also attenuate the symptoms of polydipsia (P < 0.01), polyphagia (P < 0.05), and weight loss caused by diabetes. Conclusion This study clarifies that the roots of Juandan Baihe (Lilium lancifolium) are rich in regalosides and dioscins for the first time, and have significant hypoglycemic activities, providing the foundation for the comprehensive utilization of this plant and the development of hypoglycemic drugs.

Objective:To evaluate the efficacy and safety of cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) in the treatment of pseudomyxoma peritonei (PMP).Methods:In this descriptive case series study, we retrospective analyzed the records of PMP patients treated with CRS and HIPEC between January 2013 and June 2023 at Affiliated Cancer Hospital and Institute of Guangzhou Medical University. The inclusion criteria were as follows: (1) Aged 18 to 75 years and nonpregnant women. (2) Histologically confirmed diagnosis of pseudomyxoma peritonei. (3) Karnofsky Performance Scale (KPS)>70. (4) The functions of major organs such as the heart, liver, lungs, and kidneys can tolerate major surgery for long periods of time. (5) No evidence of extra-abdominal metastasis. Patients with extensive intra-abdominal adhesions or severe infectious diseases were excluded. The main outcomes were overall survival (OS) and postoperative major complications. The postoperative major complications were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (version 5.0). We used the peritoneal cancer index (PCI) score to quantitatively assess the peritoneal metastases and the completeness of cytoreduction (CCR) score at the end of surgery (CCR-0 and CCR-1 considered to be complete CRS).Results:A total of the 186 PMP patients with a median age of 56 (interquartile range extremes (IQRE), 48-64) years were included, 65 (34.9%) males and 121 (65.1%) females. The median peritoneal cancer index (PCI) score was 28 (20-34). Appendiceal origin accounted for 91.4%. Histological types were low grade in 99 patients (53.2%), high grade in 57 patients (30.6%), and 55 patients (29.6%) received complete cytoreduction (CCR-0/1). The median operative duration was 300 (211-430) minutes for all patients. Treatment-related 30-day mortality was 2.7%; 90-day mortality 4.3%; reoperation 1.6%; and severe morbidity 43.0%. Within the entire series, anemia(27.4%), electrolyte disturbance(11.6%), and hypoalbuminemia(7.5%) were the most frequent major complications (grade 3-4). The incidences of gastrointestinal anastomotic leakage, abdominal bleeding, and abdominal infection were 2.2%, 2.2%, and 4.3%, respectively. After a median follow-up of 38.1 (95%CI:31.2-45.1) months, the 5-year OS was 50.3% (95%CI: 40.7%-59.9%) with a median survival time of 66.1 (95%CI: 43.1-89.1) months. The survival analysis showed that patients with pathological low grade, low PCI, and low CCR score had better survival with statistically significant differences (all P<0.05). Further stratified into complete and incomplete CRS subgroups, the 5-year OS of the CCR-0 and CCR-1 subgroups was 88.9% (95%CI: 68.3%-100.0%) and 77.6% (95%CI: 62.7%-92.5%), respectively; and 42.0% (95%CI: 29.5%-54.5%) in the CCR-2/3 subgroup. Conclusions:CRS and HIPEC may result in a long-term survival benefit for PMP patients with acceptable perioperative morbidity and mortality. This strategy, when complete CRS is possible, could significantly prolong survival for strictly selected patients at experienced centers.

Objective:To observe the changes of macular microvascular structure and macular pigment density (MPOD) in eyes with macular edema (ME) secondary to retinal vein occlusion (RVO), and preliminarily analyze their correlation.Methods:A prospective clinical study. A total of 62 eyes of 62 patients with monocular RVO secondary ME (RVO-ME) diagnosed in the Ophthalmology Hospital of Xi'an No.1 Hospital from July 2020 to May 2021 were included in this study. There were 33 males with 33 eyes, 29 females with 29 eyes. The age was 58.30±12.15 years. The course of disease from the onset of symptoms to medical treatment was 12.29±7.65 days. All patients underwent best corrected visual acuity (BCVA), optical coherence tomography angiography (OCTA) and MPOD test. BCVA examination was performed using a standard logarithmic visual acuity chart, which was converted to logarithm of minimum angle of resolution (logMAR). The vascular density (VD), vascular skeletal density (SD), foveal avascular area (FAZ) and central macular thickness (CMT) of the superficial retinal capillary plexus (SCP) in the range of 3 mm×3 mm in the macular area of bilateral eyes were measured by OCTA. MPOD was measured by heterochromatic scintillation photometry. Bilateral eyes passed examination in 37 cases. The eyes of 25 patients failed to pass the test. The changes of macular VD, SD, FAZ area, CMT and MPOD between the affected eyes and the contralateral eyes were compared. The MPOD of the affected eye and the contralateral eye was compared by paired t test. FAZ area, CMT, VD, SD, and logMAR BCVA were tested by paired Wilcoxon signed rank sum test. Spearman rank correlation test was used to analyze the correlation between macular blood flow density (VD, SD) and foveal morphology (FAZ area, CMT) with logMAR BCVA and MPOD. Results:Compared with contralateral eyes, VD ( Z=-5.981) and SD ( Z=-6.021) were decreased, FAZ area ( Z=-2.598) and CMT ( Z=-6.206) were increased, and the differences were statistically significant ( P<0.05). In 37 patients who passed MPOD test in bilateral eyes, the MPOD value of the affected eye was lower than that of the contralateral eye, and the difference was statistically significant ( t=-2.930, P<0.05). Compared with the affected eye which failed to pass the MPOD detection, macular VD ( Z=-2.807) and SD ( Z=-2.460) were increased, FAZ area ( Z=-4.297) and CMT ( Z=-3.796) were decreased in the affected eye which passed the MPOD test, and the differences were statistically significant ( P<0.05). Correlation analysis showed that logMAR BCVA in the affected eye was negatively correlated with macular VD and SD ( r=-0.298, -0.461; P<0.05), which was positively correlated with FAZ area and CMT ( r=0.487, 0.789; P<0.05). MPOD in the affected eye was negatively correlated with logMAR BCVA ( r=-0.344, P<0.05). MPOD in the contralateral eye was positively correlated with CMT ( r=0.358, P<0.05). Conclusions:The VD and SD of macular SCP are decreased, FAZ area is enlarged, CMT is thickened, and MPOD is decreased in RVO-ME eyes. MPOD is negatively correlated with logMAR BCVA.

Objective:To analyze the superficial retinal blood flow around the optic disc of optical coherence tomography angiography (OCTA) in non-arteritic anterior ischemic optic neuropathy (NA-AION) patients with affected eyes and contralateral healthy eyes, compared with healthy people.Methods:From May 2018 to may 2019, 30 patients with NA-AION in Xi′an No. 1 Hospital were selected. The changes of superficial retinal blood flow density and perfusion around the optic disc on OCTA of 30 patients with NA-AION, whose contralateral healthy eyes were compared. The pattern visual evoked potential (PVEP) of both eyes was also compared. 30 healthy people with no history of eye disease and history of eye surgery were selected as healthy control group, and differences between healthy control group and contralateral healthy eye group in NA-AION patients of the superficial retinal blood flow density and perfusion around the optic disc were compared.Results:The average values of serum homocysteine, apolipoprotein E and low density lipoprotein in 30 patients with NA-AION were higher than the normal reference range. Compared with the contralateral healthy eyes, the effected eyes of NA-AION patients had lower retinal blood flow density and perfusion in the center, inner layer and complete area of the optic disc, with significantly difference ( P<0.05); there was no significant difference in the latency and amplitude of PVEP-P100 between the two groups ( P>0.05). There was no significant difference in the density and perfusion of superficial retinal blood flow in the center, inner layer and complete area of the optic disc between the contralateral healthy eyes of NA-AION patients and healthy control ( P>0.05). Conclusions:OCTA is a safe, rapid and non-invasive test, and it can detect blood perfusion defects promptly, which can be used as the most commonly test method for patients with NA-AION in order to make auxiliary diagnosis and gain time for clinical treatment.
