ABSTRACT
@#Objective To identify the potential factors for psychological burdens and to better understand how the patients’ psychological status affect their treatment preferences. Methods A questionnaire survey was conducted among 996 patients with pulmonary nodules who visited the Thoracic Surgery Clinic of Guangdong Provincial People's Hospital from January to November 2021, including 381 males and 615 females, aged 47.26±11.53 years. A self-administrated questionnaire was used to investigate the sociodemographic and clinical characteristics of the patients, and the Hospital Anxiety and Depression Scale (HADS) was used to evaluate the psychological status of the patients, with a score>7 points of each subscale indicating potential anxiety or depression. Results Among the 996 patients with pulmonary nodules, the incidence of anxiety was 42.4% and the incidence of depression was 26.4%, while the incidence of both anxiety and depression was 24.7%. There was a significant correlation between anxiety and depression (ρ=0.834, P<0.05). Age, purpose of CT examination, number of pulmonary nodules and symptoms were independent factors for anxiety, while symptoms and number of pulmonary nodules were independent factors for depression (P<0.05). For treatment preferences, there was a statistical difference in educational level, symptoms, nodule size and anxiety level (P<0.05). Conclusion Anxiety and depression are common in patients with pulmonary nodules. Symptoms are associated with anxiety and depression, which also make an impact on treatment preferences.
ABSTRACT
Objective:To summarise the effect of free perforator flap of radial collateral artery on reconstruction of first web contracture after hand injury.Methods:Retrospective analysis was conducted based on the clinical data of patients with first web contracture after hand injury in the Department of Hand and Foot Surgery and Rehabilitation, Guangdong Work Injury Rehabilitation Hospital from November 2019 to June 2022. Ten patients, 8 males and 2 females aged between 27 and 51 years old with an average of 40.5 years old were included. There were 6 left hands and 4 right hands. Width and the included angle of first web were measured before surgery. Four hands were classified as severe first web contracture, and the rest of 6 hands had moderate first web contracture. After release scars of the first web, the areas of wound were 5.5 cm × 2.0 cm - 10.5 cm × 3.0 cm. The flaps sized were 6.0 cm×2.5 cm - 11.0 cm × 3.5 cm. All of flaps carried the posterior cutaneous nerve of forearm. Donor sites were closed directly. All patients were included in postoperative follow-up regularly through outpatient clinic or via WeChat reviews. The colour, texture, process in change of the transferred flaps, donor and recipient sites healing and complications were observed.Results:All 10 flaps survived and the wound healed by first intention. The patients received 7 to 15 months (10.5 months in average) of postoperative follow-up. The flaps were not bulky, texture and colour were satisfactory and without pigmentation. Protective sensations restored in 6 patients. At the last follow-up, average included angle of the first webs was 47.14°±1.68°, in comparison with 35.43°±3.60° before surgery. The average width of first webs was 5.34 cm±0.52 cm, in comparison with 3.17 cm±0.75 cm before surgery, the differences were statistically significant ( P<0.01). Eight hands were rated excellent, and 2 were good. There were only linear scars left at the donor sites, without sign of radial nerve injury. Conclusion:The free perforator flap of radial collateral artery is a safe and effective method for repair of first web contracture after hand injury.
ABSTRACT
@#Objective To explore the distribution pattern of respiratory symptoms and relevant factors in patients with pulmonary nodules. Methods Demographic and clinical information were collected from patients who visited the Thoracic Surgery Outpatient Clinic of Guangdong Provincial People’s Hospital from January 2021 to January 2022. Hospital Anxiety and Depression Scale (HADS) was used to assess their anxiety and depression level. Results A total of 1 173 patients were enrolled, including 449 males and 724 females, with an average age of 46.94±11.43 years. Among the patients with pulmonary nodules, 37.7% of them had at least one respiratory symptom; 24.4% had cough, 14.0% had expectoration, 1.3% had hemoptysis and 14.9% had chest pain. Old age, male, exposure to second-hand smoking or environmental smoke, hair coloring and history of tuberculosis were major risk factors for respiratory symptoms (P<0.05). Middle age, old age, male, exposure to environmental smoke were major risk factors for cough (P<0.05); old age, smoking, larger maximum nodules diameters, exposure to environmental smoke and history of pneumonia were major risk factors for expectoration (P<0.05); male, multiple nodules, hair coloring, exposure to second-hand smoking and history of tuberculosis were major risk factors for chest pain (P<0.05). Symptomatic patients showed generally higher HADS scores than asymptomatic patients (P<0.001). Conclusion Cough, expectoration and chest pain are the predominant respiratory symptoms for patients with pulmonary nodules. The presentation of respiratory symptoms increases patients' anxiety and depression.
ABSTRACT
The biological role of N 6-methyladenine (m 6A) methylation modification has been gradually identified, and it has shown increasing value in tumor. In recent years, with the accumulated explore of epigenetics in RNA modification, many studies have reported that m 6A methylation modification contributes to development and progression of lung cancer. m 6A-related modified regulator has potential application value as a clinical target for diagnosis and treatment of lung cancer.
ABSTRACT
Objective To evaluate the method and clinical efficacy of utilizing ilioinguinal chimeric perforator bone flap to repair bone and soft tissue defects of limb.Methods From May,2004 to February,2018,there were 11 patients who were diagnosed as bone and soft tissue defect in the upper or lower extremities,7 of which were repaired by chimeric perforator bone flap with the superficial circumflex iliac artery and 4 of which were repaired by chimeric perforator bone flap with the deep circumflex iliac artery.The size of bone flap ranged from 2.5 cm×2.0 cm× 2.0 cm to 6.0 cm×3.0 cm×2.0 cm,and the flap sizes ranged from 5.0 cm×3.0 cm to 17.0 cm×13.0 cm.The donor sites of the flap were directly sutured.Nine patients were implemented by postoperative followed-up visit in hospital.And the appearance,texture,color,shallow sensation of flaps,fracture healing,limb's function and donor site were observed.Results Postoperative followed-up ranged from 3 to 18 months.All flaps survived.The flaps had satisfactory appearance,texture and color.Osseous tissue of defects healed.The function of injury limb was restored well,which metacarpo-phalangeal joint and carpometacarpal joint's movement with metacarpal defect recovered,and gait were normal without pain.As for the donor sites,1 case had hyperplastic scar while the other only had linear scars.Abdominal hernia and numbness with lower extremities were disappeared.Conclusion Ilioinguinal chimeric perforator bone flap can be designed with different pedicles based iliac bone flap according to the size of bone defects.The donor site is concealed with less trauma and less healing time.The operation position is easy to operate,and clinic efficacy is satisfactory.
