ABSTRACT
BACKGROUND@#Immune checkpoint inhibitor associated pneumonia (CIP) is a serious side effect of immune checkpoint inhibitors. There is a consensus on the treatment of acute phase of CIP, but the treatment of pulmonary interstitial fibrosis after the acute phase is still a clinical problem to be solved.@*METHODS@#The diagnosis and treatment of a non-small cell lung cancer (NSCLC) patient with immune checkpoint inhibitor associated pneumonia in the Stereotactic Radiotherapy Department of Qingdao Central Hospital were retrospectively analyzed, and literatures were reviewed.@*RESULTS@#A 70-year-old male patient was diagnosed with Poorly differentiated squamous cell carcinoma of left lung with mediastinal lymph node metastasis T3N3M0 stage IIIc, EGFR/ALK/ROS1/RAF negative, PD-L1 (22c3) immunohistochemistry negative. After the progression of first-line chemotherapy, the patient was diagnosed as immune checkpoint inhibitor associated pneumonia grade 3 during second-line monotherapy with Nivolumab. After initial high-dose glucocorticoid pulse therapy, the lung computed tomography (CT) imaging and clinical symptoms of the patients were partially relieved, and then pirfenidone (300 mg tid) was given orally for more than 11 months. During the treatment of pirfenidone, the CT imaging and clinical symptoms of the patients were significantly improved, and there were no other adverse reactions except grade 1 nausea. During this period, chemotherapy and Anlotinib was given concurrently with pirfenidone and showed good safety profile.@*CONCLUSIONS@#This case report is the first report of pirfenidone in the treatment of CIP, which provides a new idea for the clinical practice and research of CIP treatment.
ABSTRACT
Objective To investigate the correlation between acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) scores and delirium probability of senile severe pneumonia patients undergoing invasive mechanical ventilation (MV).Methods A retrospective study was conducted. Eighty-nine senile severe pneumonia patients undergoing invasive MV admitted to intensive care unit (ICU) of Hunan Provincial People's Hospital from January 2015 to March 2017 were enrolled. APACHE Ⅱ scores were collected 24 hours before invasive MV. Consciousness assessment method-ICU (CAM-ICU) was used to diagnose delirium, and the patients were divided into delirium group and non-delirium group. The first delirium occurrence time, duration of MV and the length of ICU stay were recorded. The patients were divided into ≤15, 16-20, 21-25, 26-30, 31-35, 36-40 groups according to APACHEⅡ score, and the incidence of delirium in all groups were observed. The linear regression and Pearson correlation were used to analyze the correlation between APACHE Ⅱ scores and delirium probability. Receiver operating characteristic (ROC) curve was plotted to analyze the predictive effect of APACHEⅡ score on delirium.Results Eighty-nine patients were enrolled in the final analysis, of which 35 had delirium, and 54 had no delirium, with delirium incidence of 39.33%, and the first delirium occurrence time of (1.85±1.30) days. The duration of MV and the length of ICU stay of delirium group were significantly higher than those of non-delirium group [duration of MV (days): 9.43±4.77 vs. 6.08±3.30, length of ICU stay (days): 14.60±6.59 vs. 9.69±4.61, bothP < 0.01]. The APACHE Ⅱ score in delirium group was significantly higher than that in non-delirium group (29.89±5.45 vs. 21.48±4.76,P < 0.01). With the increase in APACHE Ⅱ scores, the delirium incidence was gradually increased. Correlation analysis showed that there was a negative correlation between APACHE Ⅱ scores and first delirium occurrence time (r = -0.411,P = 0.014), and a significant linear positive correlation between APACHE Ⅱ scores and delirium incidence in all patients was found (r = 0.982, P = 0.000), which indicated the higher APACHE Ⅱ scores, the higher delirium incidences and the earlier first delirium occurrence time was. ROC curve analysis showed that the area under ROC curve (AUC) of APACHE Ⅱ scores on predicting delirium occurrence was 0.877, when the cut-off value of APACHE Ⅱ score was over 27, the sensitivity was 92.59%, the specificity was 71.43%, the positive predictive value was 83.33%, and the negative predictive value was 86.21%.Conclusions With the increase in APACHE Ⅱ score, the incidence of delirium was increased gradually in senile severe pneumonia patients receiving invasive MV. APACHE Ⅱ score played an important clinical value in evaluating the delirium probability of these patients
ABSTRACT
BACKGROUND:StageIorIIKummel’s diseaseisusualy suggested to be treated with percutaneous vertebroplasty (PVP) orpercutaneous kyphoplasty (PKP). Stage IIIKummel’s diseasewith neurologic deficit is treated with open decompression, cement-augmented combined with internalfixation. However, surgical options for stage IIIKummel’s diseasewithdural saccompression butwithnonervous symptoms arein disputeand rarely reported. OBJECTIVE:To investigatethesurgical options of Kummel’s disease with vertebral posterior walcolapse. METHODS:Fourteen patients with Kummel’s disease with vertebral posterior wal colapse wereenroled as experimental groupandtreated with PVP or PKP based on the degree of postural reduction.Another28 patients with osteoporotic vertebral fracture as control group were treated with PKP. Thenalpatients were folowed up to observe vertebralheight, Cobb angle, visual analog scale and the Oswestry disability index. RESULTS AND CONCLUSION:After folowed up for 10 to 42 months, therestoredvertebralheight, Cobb angle, visual analog scale and Oswestry disability index were significantly improved inthetwo groups (P 0.05). These data suggest that based on the degree of postural reduction, individualizedPVP or PKP for Kummel’s disease with vertebral posterior wal colapsecanattain satisfactoryoutcomes.
ABSTRACT
Objective To investigate the correlation of incident pneumonia and serum 25-hydroxyvitamin D[25(OH)D] levels in elderly patients with fragility hip fractures.Methods 132 patients with fragility hip fractures were divided into the pneumonia group [n=43,14 males and 29 females,aged 63-97 years,a mean age of (83.8±7.1) years] and the non-pneumonia group [n=89,28 males and 61 females,aged 60-93 years,a mean age of (77.1±8.1) years].Fasting venous blood samples were taken on the second day after admission.Serum 25 (OH)D levels were measured by radioimmunoassay.Results Vitamin D deficiency was found in 90.7％ of the patients in the pneumonia group,52.8％ in the non-pneumonia group (x2=24.953,P＜0.05).The age and smoking rate were higher in the pneumonia group than in the non-pneumonia group (t=4.661,P＜ 0.05;x2 =4.459,P=0.035).Logistic regression analysis showed that serum 25(OH)D levels,age and smoking were independent impact factors for pneumonia.When serum 25(OH)D levels were less than or equal to 20 g/L,the incidence of pneumonia was increased and the risk of pneumonia was 8.66 times higher than that for patients with normal 25 (OH)D levels.Conclusions The risk of pneumonia in patients with brittle hip fractures is correlated with age,smoking and the serum 25-hydroxyvitamin D level,with the latter as a major risk factor.Patients with brittle hip fractures should be supplemented with vitamin D as early as possible in order to reduce the risk of incident of pneumonia.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the relationship between a proliferation-inducing ligand (APRIL) expression in primary tumor foci of breast cancer and the patients' prognosis.</p><p><b>METHODS</b>Paraffin sections of surgical specimens were retrospectively collected from 130 stage I-III breast cancer patients who received surgery between January 2000 and December 2002 in our hospital. Immunohistochemistry was used to assess APRIL expression intensity in the tumor cells and density of interstitial APRIL-positive cells, and their association was analyzed with the density of interstitial CD4⁺ and CD8⁺ cells and with the histopathologic features, overall survival (OS), and disease-free survival (DFS) of the patients.</p><p><b>RESULTS</b>APRIL positive staining was found in the cytoplasm of the tumor cells, interstitial cells, and the extracellular matrix. APRIL intensity in the tumor cells was positively correlated with the density of interstitial APRIL-positive cells (P=0.009) and Ki67 (P=0.003). The density of interstitial APRIL-positive cells was positively correlated with the density of interstitial CD4⁺ cells (P<0.001) and CD8⁺ cells (P<0.001). In hormone receptor negative patients (ER- and PR-), multivariate COX regression identified the density of interstitial APRIL-positive cells as a positive prognostic factor for DFS (HR=0.313, 95% CI=0.107-0.920, P=0.035). CONCLUSIONSl APRIL is widely expressed in the interstitial immune cells in breast cancer. APRIL staining intensity in the tumor cells is positively correlated with tumor proliferation, indicating that the immune cells might promote tumor proliferation by secreting APRIL. A greater density of interstitial APRIL-positive cells is associated with a good prognosis in hormone receptor-negative patients.</p>

BACKGROUND:The prevalence of osteoporosis is high in the patients undergoing total hip arthroplasty. Osteoporosis is associated with the survival of prostheses. Both canal flare index and bone mineral density are aged-related. OBJECTIVE:To study the cxorrelation between canal flare index of the proximal femur and bone mineral density of femoral neck, and to pay more attention to osteoporosis. METHODS:A retrospective study of the correlation between canal flare index of the proximal femur on pelvic radiograph and bone mineral density of femoral neck was made in 57 patients undergoing total hip arthroplasty. RESULTS AND CONCLUSION:The canal flare index were ranged 1.8-4.8 (3.1±0.7) in 57 patients. There were 23 patients in canal flare index4.7 (funnel-type medul ary cavity). The age had an impact on the type of medul ary cavity. The prevalence of chimney-type medul ary cavity were significantly higher in>60 years old group than≤60 years old group, and bone mineral density of femoral neck in the group of canal flare index≥3 was significantly higher than the group of canal flare index60 years old group [(0.751±0.235) g/cm2, (0.590±0.092) g/cm2, P=0.000]. As bone mineral density reduced, canal flare index was also decreased. Experimental findings indicate that, the bone mineral density of femoral neck is significantly correlated with canal flare index.
ABSTRACT
Objective To study the changes of bone mineral density (BMD) and structural parameters of femoral neck in fragile femoral neckfracture,and to investigate the relationship between the changes and occurrence of fragile fracture of femoral neck.Methods 102 patients were divided into fracture group (n=59) and non-fracture group (n=43).There were 18 males and 41 females [[mean age (74.0±9.3) yrs,ranged 53-88 yrs] in fracture group and 16 males and 27 females [mean age (64.3±9.9)] yrs,ranged 50-82 yrs in non-fracture group.CT scan and BMD in the femoral neck were collected in all patients.The structural parameters of the femoral neck in CT scan were measured with medical image analysis software.Results BMD was lower,cortical thickness of femoral neck (FNCT) was thinner and the ratio (FNCT/FNW) of cortical thickness (FNCT) over femoral neck width (FNW) was lower in fracture group than in non-fracture group (all P＜0.001),but there were no statistically significant differences in femoral neck width (FNW) and femoral medullary cavity width (FMCW) between the two groups (both P＞0.05).The BMD of femoral neck was markedly decreased in the fracture group as compared with the non-fracture group in patients aged 50-64 yrs (P ＜0.05),and there were no statistically significant differences in the changes of the femoral neck BMD between the two groups in patients aged over 65 yrs (P＜0.05).In both of patients aged 50-64 yrs and more than 65 yrs,FNCT was thinner and ratio of FNCT/FNW was lower in the fracture group than in the non-fracture group (both P＜0.05).The patients with osteopenia and osteoporosis had thinner FNCT and lower ratio of FNCT/FNW in the fracture group than in the non-fracture group of the patients with osteopenia and osteoporosis (both P＜ 0.01).Conclusions Lower BMD and thinner cortical thickness of femoral neck are closely related to the fragile fracture of femoral neck.The phase of femoral neck BMD rapid decline is mainly in the age of 50-65 yrs,which is consistent with the risk assessment for fragile fracture in femoral neck.The decrease of cortical thickness of femoral neck on FNCT is the main factor for the decreased femoral neck strength in patients aged over 65 yrs,which is also an important factor for the fragile fracture of femoral neck in the elderly aged over 65 yrs.
ABSTRACT
Objective To observe the mortality of fragile hip fractures and evaluate the death-associated risk factors.Methods 100 men and 186 women aged 50 to 97 (mean,77.09± 10.65) years old who had fragile hip fracture over 50 years old from 2010 to 2012 were followed up,and the clinical data were retrospectively analyzed.Three months,one year and the total mortality of following time were calculated.Mortality-related risk factors were evaluated including age,gender,and surgery,duration from injury to operation,pulmonary infection,number and kind of complications.Results The 286 patients were followed up between 6 months and 42 months,with 21.42±9.88 months in average.The three month mortality was 7.69％,the patients who were followed up over one year were 231 cases,the one year mortality was 16.02％,and the total mortality of following time was 17.48％.The mortality was associated with age,gender,surgery,duration from injury to operation,number of complications,pre-injury cardiovascular disease and respiratory system diseases,and pulmonary infection.A Binary Logistic Regression analysis revealed that the independent risk factors affecting the mortality included age (OR=5.385,P=0.003),surgery (OR=21.217,P=0.000),number of complications (OR=9.038,P=0.000),pre-injury cardiovascular disease (OR=3.201,P=0.041).Conclusion The early mortality of fragile hip fractures was high and was associated with many risk factors.Age,surgery,number of complications and pre-injury cardiovascular disease were the independent risk factors affecting the mortality of fragile hip fractures.The positive treatment with complications,early surgery in condition allowed,can lower the early mortality.
ABSTRACT
<p><b>OBJECTIVE</b>To assess the prognostic value of CD20(+) tumor-infiltrating lymphocytes (TILs) in early-stage breast cancer.</p><p><b>METHODS</b>Paraffin sections were collected from 130 cases of stage I-III breast cancer undergoing surgery between January, 2000 and December, 2002 in our hospital. Immunohistochemistry was used to analyze mesenchymal CD20(+) TILs infiltration in the tumor and evaluate its association with the density of CD4(+) and CD8(+) TILs. The association of CD20(+) TILs was evaluated with the histopathologic features, overall survival (OS), distant disease-free survival (DDFS), and disease-free survival (DFS) of the patients.</p><p><b>RESULTS</b>Aggregations of CD20(+) lymphocytes were observed in 37.69% (49/130) of the cases. CD3(+) T cells were found to aggregate around CD20(+) B cell aggregations to form lymphoid follicle-like structures. The aggregations of CD20(+) TILs were positively correlated with the densities of mesenchymal CD8+ and CD4(+) TILs. Overall, CD20(+) TIL aggregations were not significantly correlated with the outcomes of the patients, but multivariate COX regressions suggested that CD20(+) TIL aggregations were positively correlated with DDFS (HR=0.251, 95% CI=0.071-0.894, P=0.033) and OS (HR=0.325, 95% CI=0.103-1.028, P=0.056) in hormone receptor-negative patients but not in the positive patients. Further analysis suggested that post-operative adjuvant endocrine therapy significantly improved the OS of patients positive for hormone receptors without CD20(+) TIL aggregations (P=0.001).</p><p><b>CONCLUSION</b>The long-term therapeutic effects of adjuvant endocrine therapy are correlated with CD20(+) TIL aggregations to affect prognostic value of CD20(+) TIL aggregations in early-stage breast cancer patients.</p>
