Between the City and Images:An Analysis of Mainstream Media’s Paths of Constructing the Cultural Memory of a City:Taking Chengdu Radio and Television’s“Hi Chengdu”as an Example

Mainstream media play a crucial role in constructing the cultural memory of a city.This study used 319 short videos released by“Hi Chengdu,”a new media product of Chengdu Radio and Television,as samples.Based on the grounded theory,a research framework encompassing“content,technology,and discourse”was established to explore the paths through which mainstream media construct the cultural memory.Regarding content,this paper emphasized temporal and spatial contexts and urban spaces,delving deep into the themes of the cultural memory and vehicles for it.In terms of technology,this paper discussed the practice of leveraging audio/visual-mode discourse to stitch together the impressions of a city and evoke emotional resonance to create a“flow”of memory.As for discourse,this paper looked at the performance of a communication ritual to frame concepts and shape urban identity.It is essential to break free from conventional thinking and leverage local culture as the primary driving force to further boost a city’s productivity,in order to excel in cultural communication.

Thoracoscopy in Cameroon: Indications, Technics and Short Term Results

Introduction: Thoracoscopy is a video-assisted surgical approach that mirrors the techniques used in thoracotomy. Our aim is to map the current state of thoracoscopy practice in Cameroon’s hospitals. Methods: This was a descriptive study that collected both retrospective and prospective data over 57 months across four hospitals in Cameroon. It included 13 patients and focused on variables such as socio-demographic factors, clinical profiles, surgical procedures, and postoperative follow-up. Results: Thirteen patients, predominantly male (84.6%, n = 11), with a mean age of 37.5 ± 16 years, were enrolled. Alcohol use (61.5%) and smoking (38.5%) were the most common past histories. The major complaints were dyspnea (84.6%) and chest pain (58.3%). The primary surgical procedure was clot-free thoracoscopy in 30.8% of cases, mainly for persistent hemothorax (41.8%). Most surgeries were elective (76.9%) and performed under general anesthesia with selective intubation (61.5%). The most common approach was single-port thoracoscopy (U-VATS) (76.9%), with no reported difficulties;however, one intraoperative incident occurred and was successfully treated. Drainage was performed systematically in all patients, and one case required conversion to open surgery. Postoperative complications were minor (Clavien-Dindo grade I) and mainly consisted of pain, with a mortality rate of 15.4%. No significant association was found between risk factors and the occurrence of complications or postoperative mortality. Conclusion: Thoracoscopy, a novel approach in our context, primarily focuses on minor thoracic surgeries.

Diagnostic value and safety of medical thoracoscopy for pleural effusion of different causes

BACKGROUND Pleural effusions occur for various reasons,and their diagnosis remains challenging despite the availability of different diagnostic modalities.Medical thoracoscopy(MT)can be used for both diagnostic and therapeutic purposes,especially in patients with undiagnosed pleural effusion.AIM To assess the diagnostic efficacy and safety of MT in patients with pleural effusion of different causes.METHODS Between January 1,2012 and April 30,2021,patients with pleural effusion underwent MT in the Department of Respiratory Medicine,The Second Affiliated Hospital of Xi’an Jiaotong University(Shaanxi,China).According to the discharge diagnosis,patients were divided into malignant pleural effusion(MPE),tuberculous pleural effusion(TBPE),and inflammatory pleural effusion(IPE)groups.General information,and tuberculosis-and effusion-related indices of the three groups were analyzed.The diagnostic yield,diagnostic accuracy,performance under thoracoscopy,and complications of patients were compared among the three groups.Then,the significant predictive factors for diagnosis between the MPE and TBPE groups were analyzed.RESULTS Of the 106 patients enrolled in this 10-year study,67 were male and 39 female,with mean age of 57.1±14.184 years.Among the 74 thoracoscopy-confirmed patients,41(38.7%)had MPE,21 had(19.8%)TBPE,and 32(30.2%)were undiagnosed.Overall diagnostic yield of MT was 69.8%(MPE:75.9%,TBPE:48.8%,and IPE:75.0%,with diagnostic accuracies of 100%,87.5%,and 75.0%,respectively).Under thoracoscopy,single or multiple pleural nodules were observed in 81.1%and pleural adhesions in 34.0%with pleural effusions.The most common complication was chest pain(41.5%),followed by chest tightness(11.3%)and fever(10.4%).Multivariate logistic regression analyses showed effusion appearance[odds ratio(OR):0.001,95%CI:0.000-0.204;P=0.010]and carcinoembryonic antigen(OR:0.243,95%CI:0.081-0.728;P=0.011)as significant for differentiating MPE and TBPE,with area under the receiver operating characteristic curve of 0.977(95%CI:0.953-1.000;P<0.001).CONCLUSION MT is an effective,safe,and minimally invasive procedure with high diagnostic yield for pleural effusion of different causes.

Pleural lump after paragonimiasis treated by thoracoscopy: A case report

BACKGROUND Paragonimiasis is a parasitic disease that has multiple symptoms,with pulmonary types being common.According to our clinical practices,the pleural effusion of our patients is full of fibrous contents.Drainage,praziquantel,and triclabendazole are recommended for the treatment,but when fibrous contents are contained in pleural effusion,surgical interventions are necessary.However,no related reports have been noted.Herein,we present a case of pulmonary paragonimiasis treated by thoracoscopy.CASE SUMMARY A 12-year-old girl presented to our outpatient clinic complaining of shortness of breath after exercise for several days.Enzyme-linked immunosorbent assay revealed positivity for antibodies against Paragonimus westermani,serological test showed eosinophilia,and moderate left pleural effusion and calcification were detected on computed tomography(CT).She was diagnosed with paragonimiasis,and praziquantel was prescribed.However,radiography showed an egg-sized nodule in the left pleural cavity during follow-up.She was then admitted to our hospital again.The serological results were normal except slight eosinophilia.CT scan displayed a cystic-like node in the lower left pleural cavity.The patient underwent a thoracoscopic mass resection.A mass with a size of 6 cm×4 cm×3 cm adhered to the pleura was resected.The pathological examination showed that the mass was composed of non-structured necrotic tissue,indicating a granuloma.The patient remainded asymptomatic and follow-up X-ray showed complete removal of the mass.CONCLUSION This case highlights that thoracoscopic intervention is necessary when fibrous contents are present on CT scan or chest roentgenogram to avoid later fibrous lump formation in patients with pulmonary paragonimiasis.

Youth in Mainstream Arab Media： A Hybrid, Thus Consensual, Television Construct

Entertainment shows in the Arab world stand for something larger than pointless amusements shaped by producers to follow a set of marketing rules. They may be, at times, trivial or foolish but they always address the uncertainties of collective and individual identities in a region boiling with struggles over meanings and knowledge. Because of the liberalization of the Arab television industries, they have successfully integrated the global market and are now elaborating new conventions inspired by both oriental and western references. In this paper, it will explore the depiction of Arab youth as a social construct meant to challenge the nationalistic representation of this ambiguous social category while, at the same time, promoting the regional debate over modernity, Arabism, and change.

Tangents on TV： The Tangential Relationship of Narrative and Educational Content in Children＇s Television Through the Capacity Model

Previous studies have shown that children learn from educational television; however, these studies have not explored how closely the educational content of the program is integrated to the narrative. The following study uses a systematic content analysis of 100 top-rated U.S. children＇s television programs to explore the tangential relationship （i.e., distance） of narrative and educational content through the lens of the capacity model--which is built upon three basic components： narrative content, educational content, and the distance between them. Programs were analyzed for distance by examining lesson clarity and integration, show type, target audience age, and station type. One-way ANOVAs indicates significant differences between the means of these variables. Programs targeting younger children presented educational content that was closely integrated into the plotline of the program and helped further the story. However, as the target audience aged, the educational content became more tangential to the narrative content and was less tied to the plotline of the program.
