Objective:
To explore the feasibility of synthetic magnetic resonance imaging (syMRI) combined with clinicopathological characteristics for the pre-treatment prediction of chemoradiotherapy (CRT) response in advanced nasopharyngeal carcinoma (ANPC).
Materials and Methods:
Patients with ANPC treated with CRT between September 2020 and June 2022 were retrospectively enrolled and categorized into response group (RG, n = 95) and non RGs (NRG, n = 32) based on the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. The quantitative parameters from pre-treatment syMRI (longitudinal [T1] and transverse [T2] relaxation times and proton density [PD]), diffusion-weighted imaging (apparent diffusion coefficient [ADC]), and clinicopathological characteristics were compared between RG and NRG. Logistic regression analysis was applied to identify parameters independently associated with CRT response and to construct a multivariable model. The areas under the receiveroperating characteristic curve (AUC) for various diagnostic approaches were compared using the DeLong test.
Results:
The T1, T2, and PD values in the NRG were significantly lower than those in the RG (all P < 0.05), whereas no significant difference was observed in the ADC values between these two groups. Clinicopathological characteristics (Epstein–Barr virus [EBV]-DNA level, lymph node extranodal extension, clinical stage, and Ki-67 expression) exhibited significant differences between the two groups. Logistic regression analysis showed that T1, PD, EBV-DNA level, clinical stage, and Ki-67 expression had significant independent relationships with CRT response (all P < 0.05). The multivariable model incorporating these five variables yielded AUC, sensitivity, and specificity values of 0.974, 93.8% (30/32), and 91.6% (87/95), respectively.
Conclusion
SyMRI may be used for the pretreatment prediction of CRT response in ANPC. The multivariable model incorporating syMRI quantitative parameters and clinicopathological characteristics, which were independently associated with CRT response, may be a new tool for the pretreatment prediction of CRT response.

Objective To analyze the characteristics of postoperative hospital-acquired infections and drug sensitivity in lung transplant recipients over the past 5 years in a single center. Methods A total of 724 lung transplant recipients at Wuxi People's Hospital from January 2019 to December 2023 were selected. Based on the principles of hospital-acquired infection diagnosis, a retrospective analysis was conducted on the hospital infection situation and infection sites of lung transplant recipients, and an analysis of the distribution of hospital-acquired infection pathogens and their antimicrobial susceptibility test status was performed. Results Among the 724 lung transplant recipients, 275 cases of hospital-acquired infection occurred, with an infection rate of 38.0%. The case-time infection rate decreased from 54.2% in 2019 to 22.8% in 2023, showing a downward trend year by year (Z=30.98, P<0.001). The main infection site was the lower respiratory tract, accounting for 73.6%. The pathogens were mainly Gram-negative bacteria, with the top four being Acinetobacter baumannii (37.1%), Pseudomonas aeruginosa (17.3%), Klebsiella pneumoniae (13.7%), and Stenotrophomonas maltophilia (13.4%), with imipenem resistance rates of 89%, 53%, 58% and 100%, respectively. Gram-positive bacteria were mainly Staphylococcus aureus (3.6%), with a methicillin resistance rate of 67%. Conclusions Over the past 5 years, the hospital-acquired infections in lung transplant recipients have shown a downward trend, mainly involving lower respiratory tract infections, with the main pathogens being Acinetobacter baumannii, Pseudomonas aeruginosa and Klebsiella pneumoniae, all of which have high resistance rates to imipenem.

Liver metastases (LMs) are common in lung cancer. Despite substantial advances in diagnosis and treatment, the survival rate of patients with LM remains low as the immune-suppressive microenvironment of the liver allows tumor cells to evade the immune system. The impact of LMs on the outcomes of immune checkpoint inhibitors in patients with solid tumors has been the main focus of recent translational and clinical research. Growing evidence indicates that the hepatic microenvironment delivers paracrine and autocrine signals from non-parenchymal and parenchymal cells. Overall, these microenvironments create pre- and post-metastatic conditions for the progression of LMs. Herein, we reviewed the epidemiology, physiology, pathology and immunology, of LMs associated with non-small cell lung cancer and the role and potential targets of the liver microenvironment in LM in each phase of metastasis. Additionally, we reviewed the current treatment strategies and challenges that should be overcome in preclinical and clinical investigations. These approaches target liver elements as the basis for future clinical trials, including combinatorial interventions reported to resolve hepatic immune suppression, such as immunotherapy plus chemotherapy, immunotherapy plus radiotherapy, immunotherapy plus anti-angiogenesis therapy, and surgical resection.

Objective To explore the clinical utility of endoclip papilloplasty in endoscopic retrograde cholangiopancreatography(ERCP).Methods A prospective study was conducted and selected 62 patients who underwent ERCP from November 2021 to November 2022.30 out of 32 patients who randomly underwent endoclip papilloplasty were successful.These patients were assigned to successful endoclip papilloplasty group(group A,n=30)or the duodenal papilla unclamping group(group B,n=30).The aim was to compare the difference in short-term and long-term complications between the two groups.Results The success rate of papillary plasty was 93.8%(30/32),with no statistically significant differences observed in the incidence of postoperative pancreatitis,postoperative hemorrhage after ERCP,and postoperative cholangitis between the two groups(P>0.05).The duodenal perforation rate was 0.There were no significant differences between the two groups in terms of total cholangitis incidence and recurrence rate of calculus of common bile duct within 1 year(P>0.05).However,there was a statistical difference in terms of total the incidence of cholangitis+calculus of common bile duct recurrence within 1 year(P<0.05).Conclusion The endoclip papilloplasty exhibits a high success rate and safety and feasibility procedure reducing long-term recurrence rate of cholangitis and calculus of common bile duct in endoscopic papillary large balloon dilation(EPLBD)procedure.

Objective:To evaluate the differences and aesthetic meaning of stable vitiligo treatment in the face and neck region using suction blister transplantation or noncultured autologous suspension of epidermal cells.Methods:Sixty-four stable vitiligo patients (25 males and 39 females with age ranges from 10 to 46 years, average 25 years) in the face and neck region were randomly divided into two groups (32 patients in each group): one group received suction blister transplantation, while other group received noncultured autologous suspension of epidermal cells. Patients′treatment effectiveness, pigmentation and piecing deformity were evaluated in postoperative 3 months and 6 months.Results:In the postoperative 3 months and 6 months, the effectiveness of suction blister transplantation group was 68.75% (22/32) and 90.63% (29/32), respectively, while the effectiveness of noncultured autologous suspension of epidermal cells group was 59.37% (19/32) and 87.50% (28/32), respectively, in which no significant differences were found between two groups ( P>0.05). No obvious pigmentation and piecing deformity were found in noncultured autologous suspension of epidermal cells group, which were much better than the suction blister transplantation group in postoperative 3 months and 6 months. Conclusions:Both suction blister transplantation and noncultured autologous suspension of epidermal cells could bring good treatment effectiveness for patients of stable vitiligo in the face and neck region. Compared with suction blister transplantation, noncultured autologous suspension of epidermal cells could offer better aesthetic appearance.
