ABSTRACT

Objective:To analyze the risk factors of acute kidney injury (AKI) in hip fracture patients with serious underlying diseases and establish a prediction nomogram.Methods:Clinical information of hip fracture patients admitted to the intensive care unit (ICU) of Beth Israel Deaconess Medical Center (BIDMC) was analyzed using the Medical Information Mart for Intensive Care (MIMIC)-IV. Patient comorbidities, disease scores, vital signs and laboratory tests, surgical modalities, invasive procedures, and drug use were recorded. According to the diagnostic criteria of AKI in the Kidney Disease Improving Global Outcome (KDIGO) guideline, the enrolled patients were randomly divided into training set and validation set. Based on logistic regression analysis, least absolute shrinkage and selection operator (LASSO) logistic regression algorithm was used to analyze the risk factors of AKI after admission, and the corresponding prediction model was calculated.Results:A total of 474 patients were enrolled, including 331 in the training set and 143 in the validation set. According to the diagnostic criteria of AKI of KDIGO guidelines, the patients were divided into AKI group (159 cases) and non-AKI group (172 cases). Univariate analysis showed that age ( t=2.61, P=0.009), coronary heart disease (χ 2=2.08, P=0.038), heart failure (χ 2=2.60, P=0.009), hemoglobin ( t=1.89, P=0.059), platelets ( t=1.81, P=0.070), urea nitrogen ( t=2.83, P=0.005), blood creatinine ( t=3.65, P<0.001), blood sodium ( t=2.55, P=0.011), blood glucose ( t=2.52, P=0.012), anion gap ( t=3.44, P=0.001), diastolic blood pressure ( t=2.72, P=0.007), mean arterial pressure ( t=2.16, P=0.031), SOFA score ( t=3.69, P<0.001), simplified acute physiological function score II (SAPSII) score ( t=2.95, P=0.003), as well as furosemide (χ 2=2.03, P=0.042), vancomycin (χ 2=1.70, P=0.089), vasoactive medications (χ 2=3.74, P<0.001) and use of invasive mechanical ventilation (χ 2=4.81, P<0.001) were risk factors associated with the development of AKI in hip fracture patients. Multivariate logistic regression analysis showed that age ( OR=1.03, P<0.001), coronary heart disease ( OR=2.05, P=0.069), hemoglobin ( OR=0.88, P=0.050), blood creatinine ( OR=1.37, P=0.009), blood sodium ( OR=1.07, P=0.026), anion gap ( OR=1.09, P=0.028) and vasoactive medications ( OR=3.83, P=0.018) and the use of invasive mechanical ventilation ( OR=6.56, P<0.001) were independent predictors of the development of AKI in hip fracture patients with serious underlying diseases. The area under the curve of the nomogram prediction model constructed by the above 8 predictors was 0.789, and the calibration curve of the nomogram was close to the ideal diagonal. Decision curve analysis showed that the net benefit of the model was significant. Conclusion:The incidence of AKI is high in hip fracture patients with serious underlying diseases. Age, coronary heart disease, hemoglobin, serum creatinine, serum sodium, anion gap, vasoactive drugs, and invasive mechanical ventilation can predict the occurrence of AKI to a certain extent. Combined with the risk factors, the construction of the corresponding prediction model can predict and manage the diagnosis and treatment of AKI in patients with hip fracture complicated with severe underlying diseases.

ABSTRACT

Objective:To evaluate the efficacy and safety of hippocampal avoidance whole-brain irradiation with simultaneous integrated boost in the treatment of brain metastases of lung cancer.Methods:Forty lung cancer patients with brain metastases who received whole-brain radiotherapy with simultaneous integrated boost and hippocampal avoidance in Cancer Hospital, Chinese Academy of Medical Sciences from 2014 to 2020 were enrolled in this study. Brain MRI, survival follow-up and evaluation of side effects were performed before radiotherapy and at 1, 3, 6 and 12 months after radiotherapy, respectively. Overall survival (OS), progression-free survival (PFS) and changes in cognitive function were analyzed. Continuous data were described as Mean ± SD. Categorical data were described by frequency and composition ratio or percentage. Survival analysis was conducted by Kaplan-Meier method. Influencing factors of survival were identified by univariate and multivariate Cox's regression analyses.Results:A total of 40 patients were enrolled in the study. The median follow-up time was 14.2 months and the median OS, PFS and intracranial PFS of all patients were 14.8 months, 6.7 months and 14.8 months, respectively. Multivariate analysis showed that male gender and newly diagnosed stage Ⅳ disease were associated with worse OS and PFS, respectively. The Hopkins verbal learning test-revised (HVLT-R) scores at baseline and 1, 3 and 6 months after radiotherapy were 21.94±2.99, 20.88±3.12, 20.03±3.14, and 19.78±2.98, respectively. The HVLT-R score at 6 months after radiotherapy was decreased by approximately 9.8% compared with the baseline. No grade 3 or above toxic and side effect occurred in the entire cohort.Conclusion:Hippocampal avoidance whole-brain irradiation with simultaneous integrated boost is a safe and effective treatment for brain metastases of lung cancer, which is expected to reduce the impact of radiotherapy on cognitive function.

ABSTRACT

Objective:To evaluate the incidence, clinical characteristics and prognosis of second primary malignancies (SPMs) among patients with hypopharyngeal carcinoma (HPC) in real-world analysis.Methods:A total of 594 HPC patients admitted to Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from 2010 to 2018 were retrospectively analyzed.The incidence and clinical characteristics of HPC patients complicated with SPMs were analyzed. Clinical efficacy was compared among different groups.Results:With a median follow-up time of 66.9 months, SPMs were present in 36.4% (216/594) of HPC patients: 22.2% (132/594) were synchronous and 14.1% (84/594) were metachronous. The upper aerodigestive tract was the most common involved region. Compared with patients without SPMs, patients with synchronous and metachronous carcinoma in situ had similar 5-year overall survival (OS) of 42.2% vs. 44.5% ( P=0.958) and 62.2% vs. 44.5% ( P=0.240), respectively. Patients with synchronous invasive SPMs had a worse 5-year OS of 27.2% vs. 44.5% in their counterparts without SPMs ( P=0.001). Patients with metachronous invasive SPMs had similar 5-year OS of 50.2% vs. 44.5% in their counterparts without SPMs ( P=0.587). SPMs accounted for 42.5% of total death in metachronous invasive SPMs group. Conclusions:Patients with HPC have a high probability of developing SPMs. Moreover, the incidence of complicated with esophageal/gastric carcinoma in situ or metachronous SPMs exerts no effect on prognosis, while the occurrence of synchronous SPMs significantly affectes the prognosis of patients. However, the incidence of SPMs is still one of the main death causes in metachronous invasive SPMs group.

ABSTRACT

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

ABSTRACT

Objective:To analysis the clinical features and prognosis in oropharyngeal carcinoma with secondary primary tumor. Methods:A retrospective analysis was performed on 468 pathologically confirmed oropharyngeal cancer as the primary tumor patients with p16 status, excluded distant metastasis, and admitted to the Chinese Academy of Medical Sciences from January 2010 to December 2020. The clinical features and prognosis of the secondary primary tumor were analyzed. Results:Among 468 patients with oropharyngeal cancer treated at initial diagnosed, 222 cases were P16-negative. With a median follow-up time of 64.3 months, 66 cases developed second primary cancer, with an incidence of 29.3%, among which 63.6%(42/66) were synchronous and 36.4%(24/66) were heterochronous, esophagus was the most commonly involved site. The 5-year OS of p16-negative oropharyngeal carcinoma with synchronous second primary cancer, without second primary cancer and with heterogeneous second primary cancer were 26.3% and 57.3% and 73.2%(P=0.001); The second primary cancer accounted for 11.2%(12/107) of the deaths in the whole group, among them, the heterochronous second primary accounted for 75.0%(9/12). There were 246 patients with p16 positive, with a median follow-up time of 52.4 months, 20 patients developed second primary cancer(8.1%). Among them, 65.0%(13/20) were synchronous and 35.0%(7/20) were heterochronous. Esophagus was the most commonly involved site. The 4-year OS of p16-positive with synchronous, heterochronous and non-second primary cancer group were 51.9%, 80.7% and 83.3%. Secondary primary cancer accounted for 3.8%(2/52) of all deaths in p16 positvie group. Conclusion:The incidence of second primary cancer of p16 positive and negative oropharyngeal carcinoma were different. The esophagus was the most commonly involved site regardless of p16 status. Regardless of p16 status, the survival of patients with synchronous second primary cancer was worse than those without second primary cancer. For p16-negative oropharyngeal carcinoma, the prognosis was better in patients with heterogeneous second primary cancer, the second primary cancer is one of the main causes of death.

ABSTRACT

Objective:This study aimed to evaluate the clinical features and treatment outcomes of the value of response-adapted treatment following radiotherapy and induction chemotherapy follwing subsequent comprehensive therapy in patients with resectable locally advanced hypopharyngeal carcinoma. Methods:This cohort study was conducted from September 2010 to September 2020 in our hospital, 231 patients pathologically confirmed stage Ⅲ and ⅣB resectable locally advanced hypopharyngeal carcinoma included. For the IC-directed ART strategy, IC is used to select good candidates to receive radical RT or CCRT, and others undergo surgery. He response-adapted strategy was determined based on the primary tumor response, which was evaluated at a dose of 50 Gy. If the response reached complete response or partial response(more than 80% tumor regression), patients received radical RT or CCRT; otherwise, they received surgery, if possible, at 4 to 6 weeks after RT. The end points of the study were OS(overall survival), progression free survival(PFS), locoregional recurrence-free survival(LRRFS) and LDFS. Results:In IC-directed group, 75.0%(57/76) patients reached PR after 2 cycles of induction chemotherapy. While in RT-directed group, 70.3%(109/155) patients reached large PR at dose of 50 Gy. The median interquartile range follow-up period of the whole cohort was 63.8 months. The 5-year OS, PFS, LRRFS and SFL of the whole cohort were 47.9%、39.6%、44.3% and 36.2%, respectively. In evaluations based on the different treatment strategies, the 5-year OS and SFL were 51.3% versus 37.0%(HR 0.67; 95%CI 0.43-1.05; P=0.07) and 27.8% versus 39.8%(HR 0.68; 95%CI 0.46-0.99; P=0.04) between IC-directed and RT-directed groups. In additional, surgery complications did not significantly differ between these two groups. Conclusion:In this cohort study, the response-adapted strategy based on an early RT response facilitated better treatment tailoring, and higher laryngeal preservation compared with IC-directed strategies. This approach could provide a feasible laryngeal preservation strategy in patients with resectable locally advanced hypopharyngeal carcinoma.

ABSTRACT

ObjectiveTo investigate the therapeutic effect of Qingmei compound on acute gouty arthritis (AGA) in rats and preliminarily clarify its mechanism. MethodForty male SD rats were randomly divided into a blank group, a model group, a colchicine group (0.3 mg·kg-1), and low- and high-dose Qingmei compound groups (200 and 400 mg·kg-1), with eight rats in each group. The AGA model was induced by injecting 50 g·L-1 monosodium urate (MSU) into the ankle joint of the rats except those in the blank group. The ankle swelling index was measured before and 6, 24, and 48 h after modeling. The pathological changes in the joint tissues of AGA rats were observed by hematoxylin-eosin (HE) staining. The expression of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in the joint tissues of rats was detected by immunohistochemistry. The protein expression of NOD-like receptor protein 3 (NLRP3) pathway and key proteins in the joint tissues of rats was detected by Western blot. ResultCompared with the blank group, the model group showed increased ankle swelling index, synovial hyperplasia, and inflammatory infiltration, and up-regulated expression of IL-1β, TNF-α, and NLRP3 proteins in the ankle joint and the ratio of Caspase-1 shear body to Caspase-1 precursor protein (Caspase-1 p20/Caspase-1) (P<0.01). Compared with the model group, the Qingmei compound groups showed reduced ankle swelling index of AGA rats, especially the low-dose Qingmei compound group (P<0.01). Meanwhile, Qingmei compound inhibited synovial hyperplasia and inflammatory infiltration (P<0.01) and reduced the levels of IL-1β, TNF-α, and NLRP3 proteins and Caspase-1 p20/Caspase-1 in joint tissues (P<0.01). ConclusionQingmei Compound can significantly alleviate the joint swelling and inflammatory infiltration of AGA, and its mechanism may be related to the inhibition of the NLRP3 signaling pathway.

ABSTRACT

Objective:To investigate the clinical efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) on therapy-related leukemia (TRL).Methods:The clinical data of 14 patients with TRL who received allo-HSCT in Aerospace Central Hospital from April 2012 to February 2020 were retrospectively analyzed, and the therapeutic efficacy and survival status were also analyzed.Results:Of the 14 patients, 5 were males and 9 were females; the median age was 35 years old (12-59 years old). There were 12 patients with acute myeloid leukemia, 1 patient with chronic lymphocytic leukemia/small cell lymphoma, and 1 patient with acute lymphoblastic leukemia. At the time of transplantation, 4 patients achieved bone marrow complete remission, 3 patients achieved bone marrow partial remission, and the remaining 7 patients had no remission. Five patients received HLA-matched sibling transplantation, 9 patients received haplotype transplantation, and they all received myeloablative pretreatment schemes. All 14 patients were successfully implanted; the median engraftment time of granulocyte was 16 d (10-24 d), and the median engraftment time of platelet was 13 d (10-34 d). Grade Ⅰ-Ⅱ acute graft-versus-host disease (GVHD) occurred in 7 patients, chronic GVHD occurred in 6 patients, and grade Ⅲ intestinal GVHD occurred in 2 patients. The median follow-up time was 32 months (4-97 months). Among 14 patients, 5 patients died.Conclusion:The allo-HSCT can improve the prognosis and long-term survival rate of TRL patients.

ABSTRACT

Objective To evaluate the diagnostic value of quantitative detection of cytomegalovirus (CMV) DNA from different sources [plasma, sputum and bronchoalveolar lavage fluid(BALF)] for CMV pneumonia after allogeneic hematopoietic stem cell transplantation. Methods Clinical data of 405 recipients undergoing allogeneic hematopoietic stem cell transplantation were retrospectively analyzed. Among them, 19 recipients diagnosed with CMV pneumonia were assigned into the CMV pneumonia group, and 229 recipients with CMV viremia alone, 11 recipients without CMV pneumonia who received fiberoptic bronchoscopy and 16 recipients diagnosed with bacterial or fungal pneumonia based on pathogenic evidence receiving sputum culture were assigned into the control A, B and C groups, respectively. The incidence of CMV pneumonia was summarized. The CMV DNA load of specimens from different sources (plasma, sputum and BALF) of recipients with CMV pneumonia was analyzed. The clinical prognosis of recipients with CMV pneumonia was evaluated. Results Among 405 recipients undergoing allogeneic hematopoietic stem cell transplantation, 19 cases developed CMV pneumonia, and the overall incidence of CMV pneumonia was 4.7%(19/405). The CMV DNA load in the plasma, sputum and BALF of recipients with CMV pneumonia was higher than those in the control A, B and C groups (all P < 0.05). In the 19 recipients, 12 cases were cured after antiviral treatment and 7 died from treatment failure(3 cases abandoned treatment). The fatality was 37%(7/19). Conclusions Quantitative detection of CMV DNA in the plasma, sputum and BALF may increase the diagnostic rate of CMV pneumonia, thereby improving clinical prognosis of recipients undergoing allogeneic hematopoietic stem cell transplantation.

ABSTRACT

Objective:To observe the effects of the Chinese medicine prescription Xiao-Cheng-Qi decoction (XCQD) on acute brain edema and inflammatory factors in rats with severe traumatic brain injury (sTBI).Methods:A total of 108 male Sprague-Dawley (SD) rats were divided into control group, sham operation group, sTBI model group, and XCQD low, medium, high dose groups by random number table method, with 18 rats in each group. sTBI rat model was prepared according to the modified Freeney method. At 6 hours after injury, the XCQD low, medium, and high dose groups were given XCQD 1.80, 2.78, and 4.59 g/kg by gavage, respectively, and the other three groups were given the same amount of normal saline, once a day for 3 days. After 3 days of injury, rats in each group were sacrificed after the modified neurologic severity score (mNSS) assessed. Pathological changes of brain tissue were observed under light microscope after hematoxylin eosin (HE) staining, water content of brain tissue was measured by dry-wet specific gravity method, and the expressions of aquaporin 4 (AQP4), tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in brain tissue were detected by Western blotting. Serum TNF-α and IL-1β levels were detected by enzyme linked immunosorbent assay (ELISA).Results:Compared with the normal group, the mNSS score of rats increased significantly, the structure of brain tissue was disordered, and pathological changes appeared such as inflammation, edema, pyknosis of nerve nuclei, water content, the protein expressions of AQP4, TNF-α and IL-1β in brain tissue, and the contents of TNF-α, IL-1β in serum were significantly increased. After XCQD intervention, the above indexes were significantly improved. Compared with sTBI model group, the mNSS score of XCQD medium and high dose groups significantly decreased (6.94±1.16, 6.88±1.02 vs. 8.61±1.09, both P < 0.05), and the pathological changes such as brain edema and inflammation were alleviated. Brain tissue water content, AQP4 protein expression and contents of serum TNF-α, IL-1β in XCQD low, medium, and high dose groups significantly decreased compared with sTBI model group [brain tissue water content: (78.25±0.71)%, (77.62±0.44)%, (76.70±0.74)% vs. (80.08±0.66)%; the expression of brain AQP4 protein (AQP4/β-actin): 0.86±0.13, 0.84±0.22, 0.65±0.13 vs. 1.08±0.14; serum TNF-α (ng/L): 106.34±15.07, 95.75±17.26, 89.00±17.36 vs. 141.96±29.47; serum IL-1β (ng/L): 90.41±12.88, 72.82±13.51, 71.32±16.79 vs. 128.57±22.56, respectively, all P < 0.05]. The protein expressions of TNF-α,IL-1β in brain tissue of XCQD medium and high dose groups also significantly decreased compared with sTBI model group [TNF-α (TNF-α/β-actin): 0.90±0.24, 0.79±0.35 vs. 1.17±0.15; IL-1β (IL-1β/β-actin): 0.91±0.21, 0.68±0.28 vs. 1.23±0.08, respectively, all P < 0.05]. Brain tissue water content, the expression of brain AQP4 protein, the levels of brain tissue and serum IL-1β in XCQD high dose group improved more significant than those of XCQD low dose group. Conclusions:XCQD can alleviate the acute brain edema in sTBI rats, and it is dose-dependent. The mechanism may be relevant to reduce the secondary inflammatory response of sTBI by inhibiting the expression of inflammatory factors TNF-α and IL-1β.

ABSTRACT

Objective:To investigate the efficacy of allogeneic hematopoietic stem cell transplantation for acute myeloid leukemia associated with 11q23/MLL.Methods:Retrospection and analysis 50 cases of acute myeloid leukemia with 11q23/MLL and who were treated with allogeneic hematopoietic stem cell transplantation(allo-HSCT)in our hospital from September 2012 to December 2019. The efficacy was evaluated by analyzing the transplantation success rate, graft-versus-host disease rate, infection rate, transplant-related mortality(TRM), accumulative recurrence rate, disease-free survival rate(DFS), and overall survival rate(OS).Results:Except for 1 patient had an unsuccessful stem cell transplantationas the result of multiple organ failure, the remaining 49 patients were successfully transplanted. The median time of leukocyte transplantation was 15(9~18)days, and the median time of platelet transplantation was 13(8~33)days. Bone marrow was assessed 28 days after transplantation, and 49 patients were in CR status. The median follow-up time was 38(3~79)months. Between remission group and non-remission group after transplantation, the 3-year OS rates were(83.3±10.8)%, (30.9+ 8.2)%( P=0.002)and the 3-year DFS rates were(83.3+ 10.8)%, (28.4±8.0)%( P=0.003), respectively. Conclusions:Allogeneic hematopoietic stem cell transplantation is an effective method for the treatment of 11q23/MLL rearranged AML. Patients in remission before transplantation have a higher survival rate, and recurrence after transplantation is the primary problem currently faced.

ABSTRACT

Objective:To explore the influencing factors of delayed surgery for hip fracture in the elderly patients.Methods:A totally 779 elderly hip fracture patients who were hospitalized and operated in the first ward of the Department of Trauma and Hip Arthritis of Tianjin Hospital from January 2018 to December 2018 were collected. According to the time from admission to surgery, the patients were divided into early surgery group (received surgery within 48 hours after admission) 213 cases, delayed surgery group (received surgery more than 48 hours after admission) 566 cases. In this study, the following parameters were collected as potential factors affecting surgery, including: age, gender, fracture type, American Society of Anesthesiologists (ASA) classification, blood test indicators, chest radiograph, urine routine indicators, lower extremity venous thrombosis, and basic comorbidities, mental state, surgical methods, combined medication.Results:In the early operation group, there were 213 cases, 81 males and 132 females; age 69.9±10.2 years (range, 60-74 years); 95 cases of femoral neck, 118 of femoral intertrochanteric or subtrochanteric fractures; 128 cases of ASA I-II grade, 85 of III-V grade; 26 cases of abnormal cardiac function, 187 of normal; 23 cases of abnormal liver function, 190 of normal; 35 cases of abnormal renal function, 178 of normal; 104 cases of abnormal respiratory system, 109 of normal; 110 cases of electrolyte imbalance, 103 of normal; 96 cases were positive for urinary ketone bodies and 117 cases were negative; 86 cases had lower extremity venous thrombosis, 127 cases had no lower extremity venous thrombosis; 32 cases had mental disorders, and 181 cases had no mental disorders; internal fixation was selected in 102 cases, and artificial hip replacement was selected in 111 cases. There were 48 cases with combined medication and 165 cases without combined medication. In the delayed operation group, there were 566 cases, including 262 males and 304 females; age 71.7±15.6 years (range, 58-91 years); 224 cases of femoral neck fractures, 342 of femoral intertrochanteric or subtrochanteric fractures; 169 cases of ASA I-II, 397 of grade III-V; 169 cases of abnormal heart function and 397 of normal; 52 cases of abnormal liver function and 514 of normal; 90 cases of abnormal renal function and 476 of normal; 368 cases of abnormal respiratory system and 198 of normal; electrolyte imbalance 203 cases, 363 cases were normal; 261 cases were positive for urine ketone body, 305 cases were negative; 197 cases had lower extremity venous thrombosis, 369 cases had no lower extremity venous thrombosis; 141 cases had mental disorders, and 425 cases had no mental disorders; 226 cases had internal fixation as surgical method, 340 cases of artificial hip replacement were selected; 311 cases were combined with drugs, and 255 cases were not combined with drugs. There was no statistically significant difference between the early operation group and the delayed operation group in terms of age, gender, fracture type, abnormal liver function, abnormal renal function, urine ketone body, lower extremity venous thrombosis, and choice of surgical methods. There were statistically significant differences between the early operation group and the delayed operation group in terms of ASA classification, abnormal cardiac function, abnormal respiratory system, electrolyte disturbance, mental disorder, and combined medication. Multivariate Logistic regression analysis indicated that abnormal cardiac function, mental disorder, and combined medication were the influencing factors of delayed surgery for hip fracture in the elderly.Conclusion:The influencing factors of delayed surgery for hip fractures in the elderly are abnormal heart function, mental disorders, taking reserpine, clopidogrel and abnormal coagulation function.

ABSTRACT

Objective:To observe the dynamic of neurological severity scores (NSS) and the expressions of Wnt/β-catenin signaling pathway, brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) in rats with severe traumatic brain injury (sTBI), and to explore the effect of Huoxue Huayu decoction.Methods:A total of 126 Sprague-Dawley (SD) rats were randomly divided into seven groups by random number table with 18 rats in each group, namely control group (normal saline 2 kg/L), model group (normal saline 2 kg/L), brain protolysate group (BP group, 5.6 g/kg), Taohong Siwu decoction group (TH group, 10.2 g/kg), Xuefu Zhuyu decoction group (XF group, 15.6 g/kg), Tongqiao Huoxue decoction group (TQ group, 9.6 g/kg) and Buyang Huanwu decoction group (BY group, 28.7 g/kg). The sTBI rat model was reproduced by modified Feeney free fall method, and the rats in the control group were not treated with trauma. The rats in each group were intragastrical administered with corresponding drugs at 6 hours after injury, and the NSS scores were evaluated on the 1st, 3rd and 7th days after injury. After the hippocampus was harvested, the mRNA expressions of Wnt3a and β-catenin were detected by reverse transcription-polymerase chain reaction (RT-PCR), and the positive expressions of BDNF and NGF were detected by immunohistochemistry.Results:Compared with the control group, the rats in the model group showed obvious symptoms of craniocerebral injury at 1 day after injury, which was manifested as significantly increased NSS score, up-regulated mRNA expressions of Wnt3a and β-catenin, and increased positive expressions of BDNF and NGF, which indicated that the sTBI rat model was successfully prepared and presented a certain self-repair ability with the extension of time. Compared with the model group, NSS scores in the XF group, TQ group and BY group significantly decreased at 1 day after injury (6.6±1.5, 6.1±2.0, 5.7±2.4 vs. 9.4±1.5, all P < 0.05); however, the NSS scores in the BP group and TH group decreased significantly at 7 days after injury, and the NSS scores in the TQ group and BY group decreased more significantly than those in other drug groups. Compared with the model group, mRNA expressions of Wnt3a and β-catenin in the hippocampus of the BP group increased significantly at 1 day and 3 days after injury, respectively, and continued to increase with the extension of time. The mRNA expression levels of Wnt3a and β-catenin in the four groups of Huoxue Huayu decoction fluctuated to varying degrees from 1 day to 3 days after injury, but they were significantly higher than those in the model group at 7 days after injury, and the increase was more significant in the BY group [Wnt3a mRNA (2 -ΔΔCt): 154.7±4.1 vs. 17.4±1.0, β-catenin mRNA (2 -ΔΔCt): 17.05±0.45 vs. 2.74±0.13, both P < 0.05], and the second was the TQ group [Wnt3a mRNA (2 -ΔΔCt): 126.6±2.8 vs. 17.4±1.0, β-catenin mRNA (2 -ΔΔCt): 8.70±1.19 vs. 2.74±0.13, both P < 0.05]. Compared with the model group, the positive expressions of BDNF and NGF in the BP group increased significantly at 1 day after injury, but decreased after 3 days after peak. The positive expressions of BDNF and NGF in the four Huoxue Huayu decoction groups fluctuated to varying degrees from 1 day to 3 days after injury, but they were significantly higher than those in the model group at 7 days after injury, among which, the positive expressions of BDNF and NGF in the TQ group and BY group were significantly higher than those in the model group at 1 day after injury [BDNF positive cells (cells/MP): 56.4±6.2, 61.6±7.0 vs. 37.4±2.0, NGF positive cells (cells/MP): 58.4±5.0, 62.4±4.4 vs. 53.4±3.6, all P < 0.05], the increase amplitude at 7 days after injury was more significant than those in the other groups. Conclusions:Taohong Siwu decoction, Xuefu Zhuyu decoction, Tongqiao Huoxue decoction and Buyang Huanwu decoction have curative effect on the nerve regeneration and repair of rats with sTBI at acute stage, but the intensity of the effect is different. Buyang Huanwu decoction and Tongqiao Huoxue decoction have a fast and better effect.

ABSTRACT

Objective To investigate the clinical efficacy of pretreatment regimen containing idarubicin (IDA) in allogeneic hematopoietic stem cell transplantation (allo-HSCT) for high-risk refractory leukemia. Methods A total of 116 patients with high-risk refractory leukemia who received allo-HSCT treated with 7 types of IDA-containing pretreatment regimes were enrolled in this study. The implantation rate of 116 recipients was summed up. The 2-year overall survival (OS), 2-year disease free survival (DFS), cumulative recurrence rate, recurrent mortality, transplantation related mortality (TRM), cumulative incidence of acute graft-versus-host disease (aGVHD) and chronic graft-versus-host disease (cGVHD) were statistically analyzed by Kaplan-Meier survival curve. Results All 116 recipients successfully implanted. The median follow-up time was 28 (7-70) months. Among them, 64 recipients survived, the 2-year OS was 55.2%, 2-year DFS was 51.7%, 2-year recurrent mortality was 23.3% and 2-year TRM was 18.1%. Among 116 recipients, 72 cases suffered from aGVHD. The 2-year cumulative incidence rate of aGVHD was 62.1% including 20 cases of grade Ⅲ-Ⅳ aGVHD, the 2-year cumulative incidence rate was 17.2%. Among 116 recipients, 59 cases presented with cGVHD. The 2-year cumulative incidence rate was 55.4%, of which the 2-year cumulative incidence rate of extensive cGVHD was 14.7%. Among 116 recipients, 30 cases recurred with a 2-year cumulative recurrence rate of 25.9%. Conclusions IDA-containingpretreatment regime has high safety and effectiveness, and can be used as an effective pretreatment regime for transplantation preprocessing in patients with high-risk refractory leukemia.

ABSTRACT

Objective@#To investigate the efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of leukemia patients also suffering from central nervous system leukemia (CNSL) .@*Methods@#A total of 48 leukemia patients with central nervous system leukemia admitted to our hospital from May 2012 to December 2017 were retrospectively analyzed.@*Results@#① Including 22 cases of acute lymphocytic leukemia (ALL) , 21 cases of acute myeloid leukemia (AML) , and 5 cases of chronic myelogenous leukemia (CML) . Before transplantation, 19 patients achieved complete remission (CR) , and the rest 29 ones without remission. ②The conditioning regimen used TBI as the main protocol, and 6 patients were combined with whole brain and total spinal cord radiotherapy, 2 with Cyber knife treatment, and children with modified IDA combined with BUCY. ③All 48 patients were successfully transplanted, the median time for leukocyte engraftment was 14 (10-23) days, the median time for platelet transplant 16 (6-78) days. ④Bone marrow was evaluated 28 days after transplantation, all 48 patients reached CR, and DNA testing confirmed that they were all full donor chimerism. ⑤The median follow-up was 14 (2-69) months. Of them, 28 cases survived, 10 relapsed and the rest 3 had recurrence of CNSL after transplantation. One year after allo-HSCT, the overall survival (OS) of CR and non-CR groups were (77.3±10.0) % and (57.6±9.3) % (P=0.409) , respectively, the disease-free survival rates (DFS) were (71.2±11.0) % and (53.9±9.5) % (P=0.386) , respectively. The 1-year OS rates of ALL and AML groups after transplantation were (54.2±10.7) %, (80.1±8.9) %, respectively (P=0.200) , and DFS rates were (49.2±10.8) %, (75.0±9.7) % (P=0.190) , respectively.@*Conclusion@#Allo-HSCT was safe and effective for leukemia patients with CNSL.

ABSTRACT

Objective@#To evaluate the safety and efficacy of chimeric antigen receptors T cells (CAR-T) in childhood acute B lymphoblastic leukemia (B-ALL) to probe the prognosis-related factors.@*Methods@#Forty-eight children, 29 boys and 19 girls, aged 3-17years old (median age was 8 years old) , with recurrent or refractory CD19 positive B-ALL, were treated by the CD19 specific CAR-T cells. A total of 48 cases received 61 infusions. Flow cytometry or real-time quantitative polymerase chain reaction method were used to monitor micro residual disease (MRD) . The follow-up period was from 16 to 1 259 days with the median follow-up of 406 days. SPSS software was used to statistical analysis.@*Results@#No adverse reaction was observed during 61 infusions. The most common adverse reaction after CAR-T cell infusions was cytokine-release syndrome (CRS) . Only 2 cases experienced level 3 CRS performance, including continuous high fever, convulsions, delirium, serous cavity effusion, and decreasing of blood pressure. Tocilizumab was given to release CRS performance. No treatment-related death occurred. Thirty-seven patients showed response during 7 to 28 days after infusions. The early response rate was 77.1%, with MRD before infusion less than 5% group higher than the MRD more than 5% group (87.1% vs 58.8%, χ2=4.968, P=0.036) . For the 37 patients who showed response to CAR-T cell infusions, univariate analysis identified that age, disease status at the time of treatment, MRD before infusion affected 2-year OS rate (P<0.05) . Multivariate prognostic analysis for EFS disclosed that the MRD before infusion more than 5% (RR=3.433, 95% CI 1.333-8.844, P=0.011) and not bridge to HSCT (RR=4.996, 95% CI 1.852-13.474, P=0.001) were the independent risk factors.@*Conclusion@#The fourth generation CAR-T cells directed against CD19 could effectively and safely treat relapsed and refractory B-ALL, which implicated that CAR-T therapy as a novel therapeutic approach could be useful for patients with relapsed or refractory B-ALL who have failed all other treatment options. Reducing MRD as far as possible by effective pretreatment chemotherapy was in favor of increasing the response rate. Bridging HSCT after CAR-T cell treatment might be a better therapeutic strategy for the patient with refractory or molecular relapsed B-ALL.

ABSTRACT

Objective@#The aim of this retrospective study was to evaluate the prognostic significance of pretreatment Neutrophil-to-Lymphocyte Ratio(NLR) in locally advanced non-small cell lung cancer(NSCLC) patients treated with thoracic radiotherapy.@*Methods@#We retrospectively analyze 420 patients who received thoracic radiotherapy alone, sequential chemoraiotherapy or concurrent chemoradiotherapy for locally advanced stage NSCLC from January 2007 to December 2010 of our hospital. The patients were divided into two groups (high NLR group and low NLR group) with appropriate cutoff point using the receiver operating characteristic (ROC) curve method. The survival curve was established by Kaplan-Meier method. The Log-rank test was used to compare the survival of the two NLR groups and the multivariate analysis was carried out by Cox regression model.@*Results@#Among the 420 patients, 99 received radiotherapy alone, 139 received sequential chemoradiotherapy and 182 received concurrent chemoradiotherapy. 345 patients died and 75 were still alive. The median follow-up time was 5.2 years and the median overall survival was 22 months. The cut-off value of pretreatment NLR was 2.1. The 5-year PFS and OS rates in high NLR group and low NLR group were 10.6% vs 15.7% (P=0.033) and 15.5% vs 22.7% (P=0.012). Multivariate analysis confirmed that pretreatment NLR (hazard ratio 1.06, P=0.041) was independent prognostic factor of OS.@*Conclusions@#Our study revealed that the pretreatment NLR is the independent prognostic factor of OS in patients with locally advanced stage NSCLC treated with thoracic radiotherapy. However, NLR is still greatly influenced by patient′s condition and treatment which needs further research.
