Objective To investigate the current status of work readiness and its influencing factors among patients returning to work after lung cancer surgery. Methods A retrospective study was conducted on young and middle-aged postoperative lung cancer patients who were treated at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to September 2023 and returned to their jobs. Data were collected through a general information questionnaire, readiness for return-to-work scale (RRTW), general self-efficacy scale (GSES), and simplified coping style questionnaire (SCSQ). Univariate and multivariate logistic regression analyses were used to explore the factors affecting the work readiness of patients returning to work. Results A total of 219 patients were included, with 59 males and 160 females aged 18-60 years. Among the postoperative lung cancer patients returning to work, 73.1% were in the active maintenance stage of return-to-work readiness with a RRTW score of (17.59±1.48) points, and 26.9% were in the uncertain maintenance stage with a RRTW score of (16.22±1.50) points. Multivariate logistic regression analysis showed that patients aged≤30 years (OR=52.381), employees of enterprises and institutions (OR=7.682), agricultural, pastoral, fishery, forestry laborers (OR=15.665), positive coping (OR=5.043), those with higher self-efficacy (OR=1.157) and engaged in physically demanding work (OR=2.449) had higher return-to-work readiness, while patients with≥2 children (OR=0.055), self-payment (OR=0.044), and those working more than 40 hours per week (OR=0.122) had lower return-to-work readiness. Conclusion The return-to-work readiness of young and middle-aged postoperative lung cancer patients needs to be improved, and occupation, job nature, main coping styles, general self-efficacy and other factors are associated with return-to-work readiness.

In recent years, the prevalence of myopia has continued to rise, with an expanding affected population, making it a significant public health challenge both in China and globally. Elongation of the axial length in myopic eyes can induce a series of pathological changes in intraocular structure and function, increasing the risk of blinding ocular diseases such as retinal pathologies. Since myopia is difficult to reverse once established, scientific intervention is necessary to control its progression and reduce the likelihood of ocular complications. As a current research focus in myopia control, the clinical application of orthokeratology lenses has attracted considerable attention. This article highlights that orthokeratology lenses, worn overnight, reshape the corneal curvature and create a myopic defocus signal in the peripheral retina. This mechanism effectively inhibits excessive axial elongation and slows myopia progression. Clinical evidence indicates that orthokeratology can reduce axial elongation by 30% to 50%, accompanied by a short-term increase in choroidal thickness. This article also analyzes the advantages and limitations of orthokeratology and explores its potential synergistic effects when combined with other interventions such as low-dose atropine. The aim is to provide key theoretical and practical references for clinical myopia control.

Oral squamous cell carcinoma (OSCC) is a common head and neck malignancy. Approximately 50% to 60% of patients with OSCC are diagnosed at a locally advanced stage (clinical staging III-IVa). Even with comprehensive and sequential treatment primarily based on surgery, the 5-year overall survival rate remains below 50%, and patients often suffer from postoperative functional impairments such as difficulties with speaking and swallowing. Programmed death receptor-1 (PD-1) inhibitors are increasingly used in the neoadjuvant treatment of locally advanced OSCC and have shown encouraging efficacy. However, clinical practice still faces key challenges, including the definition of indications, optimization of combination regimens, and standards for efficacy evaluation. Based on the latest research advances worldwide and the clinical experience of the expert group, this expert consensus systematically evaluates the application of PD-1 inhibitors in the neoadjuvant treatment of locally advanced OSCC, covering combination strategies, treatment cycles and surgical timing, efficacy assessment, use of biomarkers, management of special populations and immune related adverse events, principles for immunotherapy rechallenge, and function preservation strategies. After multiple rounds of panel discussion and through anonymous voting using the Delphi method, the following consensus statements have been formulated: 1) Neoadjuvant therapy with PD-1 inhibitors can be used preoperatively in patients with locally advanced OSCC. The preferred regimen is a PD-1 inhibitor combined with platinum based chemotherapy, administered for 2-3 cycles. 2) During the efficacy evaluation of neoadjuvant therapy, radiographic assessment should follow the dual criteria of Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and immune RECIST (iRECIST). After surgery, systematic pathological evaluation of both the primary lesion and regional lymph nodes is required. For combination chemotherapy regimens, PD-L1 expression and combined positive score need not be used as mandatory inclusion or exclusion criteria. 3) For special populations such as the elderly (≥ 70 years), individuals with stable HIV viral load, and carriers of chronic HBV/HCV, PD-1 inhibitors may be used cautiously under the guidance of a multidisciplinary team (MDT), with close monitoring for adverse events. 4) For patients with a poor response to neoadjuvant therapy, continuation of the original treatment regimen is not recommended; the subsequent treatment plan should be adjusted promptly after MDT assessment. Organ transplant recipients and patients with active autoimmune diseases are not recommended to receive neoadjuvant PD-1 inhibitor therapy due to the high risk of immune related activation. Rechallenge is generally not advised for patients who have experienced high risk immune related adverse events such as immune mediated myocarditis, neurotoxicity, or pneumonitis. 5) For patients with a good pathological response, individualized de escalation surgery and function preservation strategies can be explored. This consensus aims to promote the standardized, safe, and precise application of neoadjuvant PD-1 inhibitor strategies in the management of locally advanced OSCC patients.

To explore the clinical efficacy of the modified segmented peroral endoscopic myotomy (POEM) for the treatment of achalasia (AC), AC patients admitted to the Jianhu People's Hospital from December 2019 to December 2021 were included in a retrospective cohort study. Patients received segmented POEM were included in the segmented POEM group, while patients treated with progressive POEM were included in the progressive POEM group. Perioperative indicators (including Eckardt scores preoperatively and at 6 months postoperatively), clinical efficacy, and complications were compared between the two groups. A total of 65 AC patients were included, among them, 28 patients were in the segmented POEM group, and 37 patients in the progressive POEM group. There were no significant differences in the general information of the two groups, including gender, age, lesion type, or Eckardt scores before the operation ( P>0.05). There were significant differences in the incidence of postoperative complications, including subcutaneous emphysema [3.6% (1/28) VS 24.3% (9/37), P=0.035] and small pleural effusion [7.1% (2/28) VS 27.0% (10/37), χ2=4.186, P=0.041] between the two groups. Postoperative chest pain duration (36.5±10.5 hours VS 44.3±11.8 hours, t=2.765, P=0.008), severity (4.1±2.1 VS 6.2±2.3, t=3.783, P<0.001), and fever days (2.1±1.3 days VS 3.1±1.5 days, t=2.816, P=0.007) also showed statistical difference. However, there was no significant difference in the incidence of postoperative pneumothorax between the two groups [0.0% (0/28) VS 2.7% (1/37), P=1.000]. At the 6-month follow-up, the segmented POEM group had a lower incidence of retrosternal pain and gastroesophageal reflux compared to the progressive POEM group ( P<0.05), and the Eckardt score was significantly improved (2.2±1.1 VS 2.9±1.3, t=2.294, P=0.025). Both segmented and progressive POEM are effective treatments for AC, but segmented POEM has higher safety, lower incidence of postoperative chest pain and gastroesophageal reflux complications, and better clinical efficacy.

Objective To explore the efficacy,safety,and technical advantages of laparoscopic combined with calyceal lithotomy in the simultaneous treatment of parapelvic cyst with renal calculi.Methods The clinical data of two patients diagnosed with parapelvic cyst and renal calculi in our hospital were retrospectively analyzed.Both patients received transabdominal laparoscopic excision of parapelvic cyst and calyceal lithotomy under general anesthesia.Preoperative CT plus intravenous pyelography(IVP)was performed to localize the calculi within the renal calyx.During operation,the cyst wall was dissected and exposed using an ultrasonic scalpel,followed by incision of the cyst wall,aspiration of cystic fluid,and excision of redundant cyst wall.Methylene blue was instilled through the ureteral catheter to mark the renal pelvis and calyces,followed by incision of the target calyx and extraction of the calculi.The changes of the cysts and calculi were analyzed.Operation time and complications were recorded.Results Both patients were admitted due to recurrent right flank pain as the chief complaint and were diagnosed with right renal multiple calculi complicated with hydronephrosis and parapelvic cysts through preoperative imaging examinations.The parapelvic cyst measured approximately 6.4 cm ×5.3 cm and 4.5 cm × 4.1 cm,respectively.The operations were successfully completed without major complications such as hemorrhage or infection.The operation time was 180 and 125 minutes,respectively.Postoperative ultrasound and abdominal plain film confirmed complete resolution of cysts and calculi.During the 2-year follow-up,both patients experienced complete resolution of flank pain with no recurrence of cysts or calculi.Conclusion Transabdominal laparoscopic combined with calyceal lithotomy is a safe and feasible technique for synchronous treatment of parapelvic cysts with renal calculi,offering advantages such as minimal trauma,rapid postoperative recovery,and low recurrence rates.This procedure should be performed in patients with parapelvic cysts larger than 4 cm.Intraoperative ureteral catheterization with methylene blue infusion is utilized to delineate the renal pelvis and calyces,which is combined with preoperative imaging findings to assist in precise stone localization.
