ObjectiveTo explore the epidemic levels and epidemiological characteristics of influenza-like illness (ILI) in Hongkou District of Shanghai, to track the trends in virus mutations, so as to offer a scientific foundation for precisely predicting influenza epidemic trends, providing early alerts, and implementing prompt prevention and control measures. MethodsData on ILI and etiological surveillance from Hongkou District between 2015 and 2024 were collected and statistically analyzed. ResultsThe consultation percentage of ILI (ILI%) in Hongkou District from 2015 to 2024 was 0.58%, and the differences were statistically significant between different years (χ²=19 280.500, P<0.001), with winter and summer being the prevalence peaks. The highest proportion of ILI cases was observed in the 25‒<60 years age group, and the proportion of cases aged ≥60 years showed an increasing trend. The positive rate for influenza viruses was 17.60%, with seasonal influenzaA (H3N2) subtype (49.78%) and influenza A(H1N1) (30.03%) being the predominant strains,and the positive rate was different by years. There was a correlation between ILI% and the positive rate of influenza viruses (r=0.260, P<0.001). The median intensity of influenza activity in 2023‒2024 was 23.09, which was significantly higher than that in 2015‒2019 (H=37.052, P<0.001) and that in 2020‒2022 (H=40.436, P<0.001). ConclusionFrom 2015 to 2022, the ILI% in Hongkou District, Shanghai remained at a relatively low level, but it significantly increased in 2023‒2024, with peaks observed in winter and summer. The predominant influenza virus strains varied and alternated by years. The 2023‒2024 period witnessed an intensified influenza activity. It is necessary to continuously monitor the impact of other respiratory pathogens on influenza epidemic, so as to provide a scientific basis for early warning and prevention and control of influenza.

ObjectiveBased on the nuclear factor erythroid 2 related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） signaling pathway， this paper explores the effect of Sinisan （SNS） on liver oxidative stress injury in cholestatic hepatitis rats and its mechanism. MethodThirty 6-week-old male SD rats were randomly divided into a control group， model group， low and high dose groups of SNS （2.5 and 5 g·kg^-1） and ursodeoxycholic acid group （UDCA， 63 mg·kg^-1）， with six rats in each group. Rats were administrated for seven consecutive days. On the 5th day， the control group was given olive oil of 10 mL·kg^-1， and the other groups were given alpha-naphthalene isothiocyanate （ANIT） of 80 mg·kg^-1. The serum biochemical indicator levels of cholestasis and the content of antioxidant factors in rat liver were detected by enzyme-linked immunosorbent assay （ELISA）. Hematoxylin-eosin （HE） staining was used to observe the pathological changes in liver tissue. The relative mRNA and protein expressions of Nrf2， HO-1， and quinone oxidoreductase 1 （NQO1） in liver tissue were detected by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot. ResultCompared with the control group， the model group showed a significant increase in the serum biochemical indicator levels of cholestasis and the content of antioxidant factors in liver tissue （P<0.01）. There were obvious pathological changes in the model group such as the disordered arrangement of hepatocytes， obvious congestion and necrosis in the portal area， infiltration of inflammatory cells， and destruction of the interlobular bile duct. The relative mRNA and protein expressions of Nrf2， HO-1， and NQO1 in liver tissue were significantly down-regulated in the model group （P<0.05， P<0.01）. Compared with the model group， the groups of SNS showed a significant decrease in the serum biochemical indicator levels of cholestasis and the content of antioxidant factors in liver tissue （P<0.01）， and the pathological liver injury was obviously improved. The necrotic area was reduced， and the infiltration of inflammatory cells was decreased. In addition， there was a small amount of extravasated blood in the interlobular vein. The relative mRNA and protein expressions of Nrf2， HO-1， and NQO1 in liver tissue were significantly up-regulated （P<0.05， P<0.01）. ConclusionSNS can significantly improve liver injury in cholestatic hepatitis rats， and its mechanism may be related to the inhibition of oxidative stress response mediated by the Nrf2/HO-1 signaling pathway.

Objective To investigate the publication status of papers written by key nursing staff of vascular interventional academic organizations and to analyze its influencing factors so as to provide a theoretical basis for improving the scientific research output of vascular interventional nursing staff.Methods The questionnaire was designed by reading and referring to the domestic and foreign literature.A survey was conducted in a total of 346 members of the Nursing Professional Committee of the China Branch of the International Vascular Alliance,who were from 22 provinces,autonomous regions,and municipalities of China.Results Of the 346 key vascular interventional nursing staff,190 had published one paper(54.91％)and 156(45.09％)had published multiple papers in the past 5 years as the first author or corresponding author,and among them 267(77.17％)wrote papers for the purpose to make a promotion.Multiple regression analysis showed that academic position,first education degree,professional position,length of nursing service,knowledge of the English literature,and source of scientific research knowledge(school study)were the independent factors affecting the paper publication by vascular interventional nursing staff(all P＜0.05).The survey showed that vascular interventional nursing staff had difficulties in carrying out scientific research because they were lack of scientific research-related knowledge,busy with daily work,and lack of scientific research atmosphere.Conclusion The publication of academic papers written by key nursing staff of vascular interventional academic organizations is influenced by many factors.It is recommended that the hospital administration should strengthen the training of English literature retrieval ability for nursing staff so as to fundamentally improve the overall scientific research level of nursing staff.(J Intervent Radiol,2024,33:309-313)

By consulting the ancient and moderm literature， this paper makes a textual research on the name， origin， quality evaluation， harvesting and processing of Olibanum， so as to provide a basis for the development of the famous classical formulas containing this medicinal material. According to the herbal textual research， the results showed that Olibanum was first described as a medicinal material by the name of Xunluxiang in Mingyi Bielu（《名医别录》）， until Ruxiang had been used as the correct name since Bencao Shiyi（《本草拾遗》） in Tang dynasty. The main origin was Boswellia carterii from Burseraceae family. The mainly producing areas in ancient description were ancient India and Arabia， while the modern producing areas are Somalia， Ethiopia and the southern Arabian Peninsula. The medicinal part of Olibanum in ancient and modern times is the resin exuded from the bark， which has been mainly harvested in spring and summer. It is concluded that the better Olibanum has light yellow， granular， translucent， no impurities such as sand and bark， sticky powder and aromatic smell. There were many processing methods in ancient times， including cleansing（water flying， removing impurities）， grinding（wine grinding， rush grinding）， frying（stir-frying， rush frying， wine frying）， degreasing， vinegar processing， decoction. In modern times， the main processing methods are simplified to cleansing， stir-frying and vinegar processing. Nowadays， the commonly used specifications include raw， fried and vinegar-processed products. Among the three specifications， raw products is the Olibanum after cleansing， fried products is a kind of Olibanum processed by frying method， vinegar-processed products is the processed products of pure frankincense mixed with vinegar. Based on the research results， it is recommended to select the resin exuded from the bark of B. carterii for the famous classical formulas such as Juanbitang containing Olibanum， processing method should be carried out in accordance with the processing requirements of the formulas， otherwise used the raw products if the formulas without clear processing requirements.

AIM: To analyze the mechanism of Usher syndrome(USH)caused by Adgrv1 gene variation through the Hedgehog(Hh)signaling pathway.METHODS: Based on Adgrv1 gene variant mice(Adgrv1-/-), taking wild type(WT)C57BL/6 mice as controls, the expression of Adgrv1 gene and the structure of retina and cell cilia were analyzed by qRT-PCR, HE, transmission electron microscopy, and immunofluorescence. Additionally, the changes of key factors in the Hh signaling pathway caused by Adgrv1 gene variation were observed.RESULTS: The Adgrv1 gene was expressed in both the retina and primary cultured lung fibroblasts of Adgrv1-/- mice, but the expression levels were significantly decreased. The Adgrv1 gene variation can cause dissolution of the outer disc membrane of the retinal photoreceptors and significantly shorten the cilia length in primary lung fibroblasts. In the Hh signaling pathway, the expression of Ptch1 and Gli genes of Adgrv1-/- was significantly reduced, while the expression of PKA genes was increased.CONCLUSION:The Adgrv1 gene variation leads to shortened cell cilia and dissolution of the outer disc membrane of the retinal photoreceptors, resulting in retinitis pigmentosa, which is related to decreased expression of PTCH1 and GLI1 proteins in the Hh pathway.

Objective:To learn about physicians’ concepts and commonly employed method in hyaluronic acid injection and provide reference data for the standardization of pain management.Methods:This study was a cross-sectional study. Convenient sampling method was used to distribute questionnaires to cosmetic injectors and patients experienced with hyaluronic acid injections to collect data on their views of pain associated with hyaluronic acid injections. The physician portion was collected offline from June 15 to July 20, 2022, and the patient portion was collected from November 14, 2022, to December 6, 2022, via the Questionnaire Star platform. The physician questionnaire consisted of 17 questions, question types included single choice, multiple choice and essay questions. The patient questionnaire consisted of 6 questions, question types included single choice and multiple choice. Relevant data were analyzed using SPSS 22.0 software for descriptive statistics, and data were presented in the form of cases and percentages (%).Results:Sixty-two physician questionnaires and 123 patient questionnaires were collected. 42 (67.74%) physicians observed from their daily practice that more than 50% of their patients were very concerned about pain during injection; 101 (82.11%) patients scored ≥5 out of 10 for concern about impending pain prior to hyaluronic acid filler injection. At the time of treatment, 48 (77.42%) physicians advised patients to choose a lidocaine-containing hyaluronic acid filler for reasons including a significant reduction in injection pain (53 cases, 85.48%) and patient comfort with the treatment experience (59 cases, 95.16%). 60 (48.78%) patients were willing to choose an anesthesia-containing product at the time of injection, but the price of the anesthesia-containing product influenced the patient’ s choice (55 cases 44.72%) .Conclusions:Pain from cosmetic injectable treatments is an important issue to both physicians and patients. Lidocaine-containing hyaluronic acid is recognized by physicians and patients for its analgesic effect and high safety profile. There is no perfect solution for pain in cosmetic injection treatment, and multidisciplinary collaboration may be needed to solve the problem.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To establish a nomogram model for predicting the hyper-progression recurrence after hepatectomy in patients with hepatocellular carcinoma (HCC) based on circulating tumor cells (CTC).Methods:Clinical data of 231 HCC patients undergoing hepatectomy at the Department of Hepatobiliary Surgery, Guangxi Medical University Cancer Hospital from January 2013 to December 2022 were retrospectively analyzed, including 200 males and 31 females, aged 46(39, 52) years old. Patients were divided into two groups: the modeling group ( n=154) and the validation group ( n=77). According to the state of postoperative hyper-progression recurrence, patients in the modeling group were subdivided into hyper-progression recurrence ( n=39) and non-hyper-progression recurrence group ( n=115). Patients in the validation group were also subdivided into hyper-progression recurrence ( n=16) and non-hyper-progression recurrence group ( n=61). Clinicopathological data such as the total CTC count, alpha-fetoprotein, and postoperative pathology were collected. Logistic regression analysis was used to analyze the influencing factors of postoperative hyper-progression recurrence. A nomogram model was established based on the results of multivariate logistic regression analysis. The receiver operating characteristic (ROC) curve, calibration curve, decision curve analysis (DCA) and clinical impact curve (CIC) were used to validate the nomogram model. Results:Multivariate logistic regression analysis showed that HCC patients with age ≤45 years old ( OR=6.704, 95% CI: 1.619-27.760, P=0.009), incomplete tumor capsule ( OR=13.292, 95% CI: 3.084-57.295, P=0.001), high total numbers of CTC ( OR=1.101, 95% CI: 1.023-1.186, P=0.011) and high Ki67 index ( OR=52.659, 95% CI: 3.215-862.604, P=0.005) had a high risk of hyper-progression recurrence after hepatectomy. The above three preoperative variables were integrated to construct a nomogram model. The calibration curve showed that the predicted results of the nomogram model were in good agreement with the actual results. The ROC curves of the nomogram model for predicting hyper-progression recurrence after hepatectomy in HCC patients were plotted, and the area under the curve was 0.907 (95% CI: 0.856-0.959) and 0.833 (95% CI: 0.721-0.945) in the modeling group and validation group, respectively. DCA showed that the nomogram model could be used as a valuable predictive tool for the hyper-progression recurrence after hepatectomy. The CIC showed that the population judged by the nomogram model was highly matched with the actual population with hyper-progression recurrence. Conclusions:This study established a nomogram model based on age, tumor capsular integrity and total CTC count, which could accurately predict the postoperative hyper-progression recurrence in HCC patients before hepatectomy. The model is promising in guiding clinical practice after further validation.
