Cancer immunotherapy refers to the therapeutic effect of controlling or eliminating tumor cells by interfering with the immune system to restore the anti-tumor immune response. Immune checkpoint inhibitor therapy that blocks programmed death -1/programmed cell death ligand-1/cytotoxic T lymphocyte-associated antigen 4 is one of the most commonly used tumor immunotherapies, with good efficacy and wide application. These drugs cause immune-related ocular complications such as uveitis, autoimmune retinopathy, and scleritis, which represent a new etiology of ocular inflammation. The ophthalmologist's grasp of the clinical characteristics of these diseases is helpful for timely diagnosis. At the same time, the ophthalmologist will work closely with the oncologist to make a comprehensive judgment based on the patient's primary tumor, survival prognosis, severity of adverse reactions related to ocular immunotherapy, and visual prognosis, and develop suitable therapeutic strategie, thereby saving the patients' vision and improving the quality of life.
ObjectiveTo analyze the health examination results of hospital retirees, understand their health status and provide the evidence for health management. MethodsThe data were collected from our 1 089 hospital retirees (51-96 years old) who received health examination in West China Hospital of Sichuan University from January to December 2013, including 345 males and 744 females, with a mean age of 70 years. The data were analyzed by SPSS 16.0 software. ResultsHypertension, dyslipidemia and diabetes were the three chronic diseases with the highest detectable rate, and the rate was respectively 49.49%, 44.90% and 31.04%. The detectable rate of hypertension was not significantly different between male and female. The rate of dyslipidemia in females was higher than that in males. The rate of diabetes in males was higher than that in females. The detectable rate of hypertension and diabetes increased with the increase of age. The detectable rate of dyslipidemia had no significant relationship with age. ConclusionThe health condition of retirees cannot be neglected. We need to strengthen the health management for the retirees.

ObjectiveTo evaluate the effect of postoperative no indwelling urethral catheters in lung operation. MethodsIn this prospective cohort study, we recruited 100 patients who were scheduled for pulmonary lobectomy under general anesthesia in a single institution of Thoracic Surgery Department in West China Hospital between April and December 2014. These patients were divided into two groups including a no indwelled urethral catheter group (NIUC, 50 patients) and an indwelled urethral catheter group (IUC, 50 patients). The clinical effect was compared between the two groups. ResultsThere was no statistical difference in incidence of postoperative urinary retention or urinary tract infection between the two groups (P=0.433, 0.050). However, the comfort degrees(0 degree) of patients in the NICU group was significantly higher than that of the ICU group with a statistical difference (P=0.002). While postoperative hospitalization time in the NICU group (P=0.023) was shorter than that in the ICU group (P=0.004). Prostatic hyperplasia was the high risk factor for the lung postoperative urinary retention (P=0.056). ConclusionPostoperative no indwelling urethral catheters in lung operation has the benefit of improving the comfort degrees of inpatients and increasing the postoperation urinary retention.
ObjectiveTo analyze the causes and potential risk factors of re-catheterization after failure of no urinary catheter in patients undergoing lung cancer surgery.MethodsThe clinical data of 1 618 patients without urinary catheter indwelling during the perioperative period of thoracic surgery in our hospital from 2013 to 2019 were retrospectively analyzed, including 791 males and 827 females, with a median age of 58 years, ranging from 27 to 85 years. And the risk factors for re-insertion after failure of urinary catheter were investgated.ResultsThe rate of catheter re-insertion was 1.5% (24/1 618). Compared with patients without re-insertion, patients with re-insertion had longer operation time [120.0 (95.0, 130.0) min vs. 120.0 (115.0, 180.0) min, P=0.015] and more intraoperative fluid infusion [800.0 (600.0, 1 100.0) mL vs. 1 150.0 (725.0, 1 350.0) mL, P=0.008]. Further multivariate analysis found that the operation time (OR=1.014, P=0.004, 95%CI 1.005-1.024) and intraoperative fluid infusion (OR=1.001, P=0.022, 95%CI 1.001–1.002) were independent risk factors for re-insertion.ConclusionThe rate of catheter re-insertion in lung cancer patients is relatively low, and conventional no placement of catheter is safe and feasible after lung cancer surgery. Increasing operation time or intraoperative infusion volume may increase the risk of catheter re-insertion after lung cancer surgery.
ObjectiveTo investigate the effect of repairing radial bone defect with scaffold material of attapulgite/collagen type I/poly (caprolactone) (ATP/Col I/PCL) in rabbits and the possibility as bone graft substitutes. MethodsATP/Col I/PCL materials were prepared via adding ATP to hexafluoroisopropanol after dissolved Col I/PCL (3∶2), and Col I/PCL materials via dissolving Col I/PCL (3∶2) in hexafluoroisopropanol served as control. The structure of scaffolds was observed under scanning electron microscope (SEM). Twenty-four Japanese white rabbits (male, 2 months old) were used to establish the bilateral radius defect model of 15 mm in length, and randomly divided into group A (6 rabbits, 12 defects), group B (9 rabbits, 18 defects), and group C (9 rabbits, 18 defects); then the Col I/PCL scaffold was implanted in the bone defect area in group B, the ATP/Col I/PCL scaffold in group C, no treatment was done in group A as control. The general condition of rabbits was observed after operation, and bone defect repair was evaluated by X-ray at 4, 8, and 12 weeks. At 12 weeks, the tissue of defect area was harvested for the general, SEM, Micro-CT, histological, and immunohistochemical staining to observe defect repair and material degradation. ResultsSEM observation showed that two kinds of materials were porous structure, ATP/Col I/PCL structure was more dense than Col I/PCL. All animals survived to the end of experiment, and no incision infection occurred during repair process.X-ray films showed that the bone marrow cavity was re-opened in defect area of group C with time, the repair effect was superior to that of groups A and B. At 12 weeks after operation, general observation showed that scaffold material had good fusion with the surrounding tissue in groups B and C, defect was filled with connective tissue in group A. SEM indicated that the surface and pore of the scaffold were covered with a large number of cells and tissues in groups B and C. Micro-CT demonstrated that the new bone volume, bone mineral content, tissue mineral content, and connectivity density of group C were significantly higher than those of groups A and B (P<0.05). The observation of histology and immunohistochemical staining indicated that there were lots of connective tissues in defect area of group A, and ALP, Col I, and OPN were weakly expressed; there were many collagen fibers in scaffold degradation area in group B, and the expression levels of ALP, Col I, and OPN were higher than those of group A; there was few new bone in group C, the degradation rate of the scaffold was slower than that of group B, and the expression of Col I and OPN were enhanced, while ALP was weakened when compared with groups A and B. ConclusionATP/Col I/PCL composite scaffold material can degrade in vivo, and has dense three-dimensional porous structure, good biocompatibility, and high potentiality of bone repair, so it can be used as bone substitute material.
ObjectivesTo analyze the balance of medical human resource allocation in Chengdu and to discuss the impact of human resource allocation structure on the hospital’s medical service capabilities, so as to provide a theoretical basis for the hospital to optimize the talent team structure.MethodsThe Moran’s index and Gini coefficient were used to evaluate the spatial aggregation and grade distribution difference of human resources allocation, respectively. The case mix index (CMI), the length of hospital stay, and the difficulty of surgery were used as outcome variables, and a multiple regression analysis model was established to explore the impact of human resource indicators on the hospital’s medical service capabilities.ResultsThe distribution of doctors showed an obvious spatial aggregation in Chengdu, and there was a positive spatial correlation (Moran’s Idoctor=0.290); the distribution of nurses had no obvious spatial aggregation (Moran’s Inurse=0.102). Under different medical service capacity segments, the Gini coefficient of doctors was 0.518, and the Gini coefficient of nurses was 0.576, both exceeding 0.5, indicating that the distribution of medical human resources in different levels of hospitals was considerably different. The regression results showed that the expansion of the quantity of senior title doctors and the proportion of medical care both could improve the hospital’s CMI. The increase in the quantity of doctors with senior titles also had a certain impact on improving the hospital’s surgical capabilities. The expansion of the proportion of medical care could lead to a slight increase in the length of patients' hospital stay.ConclusionsOptimizing the allocation structure of medical human resources in different regions and hospitals with different levels is an important task in the construction of a hierarchical diagnosis and treatment system. It is necessary to further integrate medical human resources throughout the whole city and strengthen personnel training and team building in primary health institutions. Hospitals at different levels should implement their own development positioning and further optimize their human resource allocation structure according to development needs. Tertiary hospitals should pay more attention to the cultivation of senior professional doctors, optimize the proportion of medical care, and improve the hospital’s medical service capabilities. The primary health institutions should pay attention to the comprehensive construction of medical personnel, and strengthen the development of the team of general practitioners, so as to achieve a comprehensive improvement of the city’s medical service capabilities.
