ABSTRACT

Tenofovir disoproxil fumarate (TDF) is a first-line treatment for chronic hepatitis B. With increasing use worldwide, the adverse events of renal injury caused by this drug have also attracted industry attention. This article reports a 61- year-old patient with liver cancer complicated with hepatitis B virus (HBV) infection. The patient started using TDF in mid-March 2022 and developed kidney injury after 2 months of treatment, during which he received 2 courses of donafenib combined with sintilimab chemotherapy and irregular administration of diclofenac for pain relief. In this paper, Naranjo’s assessment scale was used to evaluate the drugs that may be associated with renal injury, including TDF and sintilimab, and the drugs that are suspected to be associated with renal injury are donafenib and diclofenac. The renal injury caused by TDF can be judged according to the changes in the patient’s condition, the incidence of drug-induced renal injury, clinical manifestations, occurrence time, occurrence mechanism, drug combination, and high-risk factors. The changes of serum creatinine in patients with liver cancer complicated with HBV infection after TDF should be dynamically monitored in the clinic, and the dose of antiviral drugs should be adjusted if necessary and other antiviral drugs with less impact on renal function can be selected, to provide individualized medication recommendations for tumor patients, reduce the incidence of TDF-related renal injury.

ABSTRACT

With a global rise in morbidity rates, obesity has become a pressing public health issue. With increased adipocyte number and volume as the main characteristics, obesity is also manifested by metabolic disorders to varying degrees. At the same time, obesity is a risk factor for diabetes, hypertension, stroke, cancer, and cardiovascular diseases, imposing burdens on society and families. Influenced by lifestyle, environment, behavior, and genetics, obesity is caused by the interaction of many factors, and its pathological process is complex, involving inflammation, autophagy, and intestinal dysbiosis. The mitogen-activated protein kinase (MAPK) cascade reaction, a pivotal signaling pathway, plays a crucial role in cellular processes such as proliferation, differentiation, apoptosis, and stress responses. Both Chinese and international studies indicate that the MAPK signaling pathway can effectively regulate obesity through various pathways, including the modulation of adipocyte differentiation and apoptosis, appetite control, and inflammation improvement. Moreover, traditional Chinese medicine (TCM) has demonstrated significant efficacy in preventing and treating obesity, leveraging advantages such as multiple targets, diverse components, and minimal adverse effects. Research indicates that the MAPK signaling pathway is a primary focus of TCM regulation in this context, although a systematic review in this field is currently lacking. Therefore, this paper, by reviewing the latest Chinese and international research, provided a concise overview of the basic structure of the MAPK pathway, with a specific emphasis on recent progress in TCM interventions targeting the MAPK pathway for obesity treatment. The results indicate that regulating adipose tissue formation, differentiation, and thermogenesis, reducing inflammation and oxidative stress levels, and improving insulin sensitivity and metabolic disorders seem to be the main ways for TCM to regulate the MAPK pathway to prevent and treat obesity. However, it is necessary to find more research methods and explore potential mechanisms underlying TCM formulations based on the MAPK pathway for obesity prevention and treatment.

ABSTRACT

Objective:To compare and analyze the efficacy and safety of intraoperative radiotherapy (IORT) combined with conventional therapy (surgery combined with radiochemotherapy) and conventional therapy alone for pancreatic cancer.Methods:Literature review was conducted from PubMed, Cochrane Library, Web of Science, Embase, Chongqing VIP, CNKI, Wanfang Data and China Biomedical Literature Service System (SinoMed). The literatures that met the inclusion criteria were screened and the data were extracted. Meta-analysis was carried out by RevMan 5.4 software.Results:A total of 11 studies consisting of 813 patients were included. According to the combined results, compared with conventional therapy, IORT combined with conventional therapy could improve the overall survival rate of pancreatic cancer ( HR=0.66, 95% CI=0.54-0.81, Z=4.03, P<0.001), and did not increase the treatment-related side effects ( OR=1.00, 95% CI=0.69-1.46, Z=0.01, P=0.99), but failed to bring benefit to the local control rate ( HR=0.56, 95% CI=0.31-1.01, Z=1.93, P=0.05). Conclusions:The overall survival rate in the IORT combined with conventional therapy group is significantly better than that in the conventional therapy group. No significant difference is found in the treatment-related adverse reactions between two groups. IORT combined with conventional therapy is worthy of clinical application.

ABSTRACT

Male diabetic individuals present a marked impairment in fertility; however, knowledge regarding the pathogenic mechanisms and therapeutic strategies is unsatisfactory. The new hypoglycemic drug dapagliflozin has shown certain benefits, such as decreasing the risk of cardiovascular and renal events in patients with diabetes. Even so, until now, the effects and underlying mechanisms of dapagliflozin on diabetic male infertility have awaited clarification. Here, we found that dapagliflozin lowered blood glucose levels, alleviated seminiferous tubule destruction, and increased sperm concentrations and motility in leptin receptor-deficient diabetic db/db mice. Moreover, the glucagon-like peptide-1 receptor (GLP-1R) antagonist exendin (9-39) had no effect on glucose levels but reversed the protective effects of dapagliflozin on testicular structure and sperm quality in db/db mice. We also found that dapagliflozin inhibited the testicular apoptotic process by upregulating the expression of the antiapoptotic protein B-cell lymphoma 2 (BCL2) and X-linked inhibitor of apoptosis protein (XIAP) and inhibiting oxidative stress by enhancing the antioxidant status, including total antioxidant capacity, total superoxide dismutase (SOD) activity, and glutathione peroxidase (GPx) activity, as well as decreasing the level of 4-hydroxynonenal (4-HNE). Exendin (9-39) administration partially reversed these effects. Furthermore, dapagliflozin upregulated the glucagon-like peptide-1 (GLP-1) level in plasma and GLP-1R expression by promoting AKT8 virus oncogene cellular homolog (Akt) phosphorylation in testicular tissue. Exendin (9-39) partially inhibited Akt phosphorylation. These results suggest that dapagliflozin protects against diabetes-induced spermatogenic dysfunction via activation of the GLP-1R/phosphatidylinositol 3-kinase (PI3K)/Akt signaling pathway. Our results indicate the potential effects of dapagliflozin against diabetes-induced spermatogenic dysfunction.

ABSTRACT

OBJECTIVE@#We propose a novel region- level self-supervised contrastive learning method USRegCon (ultrastructural region contrast) based on the semantic similarity of ultrastructures to improve the performance of the model for glomerular ultrastructure segmentation on electron microscope images.@*METHODS@#USRegCon used a large amount of unlabeled data for pre- training of the model in 3 steps: (1) The model encoded and decoded the ultrastructural information in the image and adaptively divided the image into multiple regions based on the semantic similarity of the ultrastructures; (2) Based on the divided regions, the first-order grayscale region representations and deep semantic region representations of each region were extracted by region pooling operation; (3) For the first-order grayscale region representations, a grayscale loss function was proposed to minimize the grayscale difference within regions and maximize the difference between regions. For deep semantic region representations, a semantic loss function was introduced to maximize the similarity of positive region pairs and the difference of negative region pairs in the representation space. These two loss functions were jointly used for pre-training of the model.@*RESULTS@#In the segmentation task for 3 ultrastructures of the glomerular filtration barrier based on the private dataset GlomEM, USRegCon achieved promising segmentation results for basement membrane, endothelial cells, and podocytes, with Dice coefficients of (85.69 ± 0.13)%, (74.59 ± 0.13)%, and (78.57 ± 0.16)%, respectively, demonstrating a good performance of the model superior to many existing image-level, pixel-level, and region-level self-supervised contrastive learning methods and close to the fully- supervised pre-training method based on the large- scale labeled dataset ImageNet.@*CONCLUSION@#USRegCon facilitates the model to learn beneficial region representations from large amounts of unlabeled data to overcome the scarcity of labeled data and improves the deep model performance for glomerular ultrastructure recognition and boundary segmentation.

ABSTRACT

Objective To investigate the expression of programmed death ligand 1(PD-L1) in primary tumor cells(TCs) and tumor-infiltrating immune cells(TICs) in patients with liver metastases from colorectal cancer(CRC) and determine its predictive value for recurrence after microwave ablation(MWA) of liver metastases. Methods The paraffin-embedded specimens of 28 patients with CRC liver metastasis were collected retrospectively. The expression of PD-L1 in the primary lesions was detected by immunohistochemistry, and the relationship between PD-L1 and clinical features was analyzed. Recurrence-free survival(RFS) was analyzed by Kaplan-Meier method and Log rank test. Cox proportional hazards regression model was used to analyze the factors influencing recurrence. Results The positive rates of PD-L1 in TCs and TICs in primary CRC were 14.3%(4/28) and 46.4%(13/28), respectively. PD-L1 expression in primary TICs of CRC patients with liver metastases was significantly correlated with the largest hepatic tumor diameter (P < 0.05). PD-L1 expression in primary TICs of CRC patients with liver metastasis was correlated with poor RFS after MWA (P < 0.05). PD-L1 expression in primary TICs and the largest hepatic tumor diameter > 3 cm in CRC patients with liver metastases were the risk factors for recurrence after MWA (P < 0.05). Conclusion PD-L1 expression in primary TICs of CRC patients with liver metastasis may increase the risk of recurrence after MWA for liver metastasis.

ABSTRACT

Objective: To understand the vaccination status of enterovirus type 71 (EV71) inactivated vaccines in China from 2017 to 2021 and provide evidence for making policy on immunization strategy against hand, foot and mouth disease (HFMD). Methods: Using the reported dose number of EV71 vaccination and birth cohort population data collected by the China immunizaiton program information system to estimate the cumulative coverage of EV71 vaccine by the end of 2021 among the birth cohorts since 2012 at national, provincial, and prefecture levels, and analyze the correlation between the vaccination coverage and the potential influencing factors. Results: As of 2021, the estimated cumulative vaccination coverage of the EV71 vaccine was 24.96% in birth cohorts since 2012. The cumulative vaccination coverage was between 3.09% and 56.59% in different provinces, between 0 and 88.17% in different prefectures. There was a statistically significant correlation between vaccination coverage in different regions and the region's previous HFMD prevalence and disposable income per capita. Conclusions: Since 2017, the EV71 vaccines have been widely used nationwide, but the coverage of EV71 vaccination varies greatly among regions. Vaccination coverage is higher in relatively developed regions, and the intensity of previous epidemic of HFMD may have a certain impact on the acceptance of the vaccine and the pattern of immunization service. The impact of EV71 vaccination on the epidemic of HFMD requires further studies.

ABSTRACT

Objective:To explore the clinical efficacy and adverse reactions of albumin-bound paclitaxel (Nab-P) and conventional paclitaxel combined with cisplatin and concurrent radiotherapy for the treatment of patients with locally advanced esophageal squamous cell carcinoma.Methods:Forty-nine patients with locally advanced esophageal squamous cell carcinoma admitted to the First People's Hospital of Suqian from November 2016 to May 2020 were included. Of the 49 patients, 23 cases were treated with Nab-P combined with cisplatin and concurrent radiotherapy (NP group), 26 cases were treated with conventional paclitaxel combined with cisplatin and concurrent radiotherapy (TP group). All patients received 2 cycles of chemotherapy. The curative efficacy was evaluated one month after the end of radiotherapy, and the curative effect and adverse reactions of the two treatment regimens were compared.Results:The objective remission rate in NP group was 78.3% (18/23), and the disease control rate was 100.0% (23/23). The objective response rate in TP group was 61.5% (16/26), and the disease control rate was 92.3% (24/26). The objective response rate and disease control rate in NP group were higher than those in TP group, but the differences were not statistically significant (both P > 0.05). The common adverse reactions were mainly hair loss, loss of appetite, bone marrow suppression, radiation esophagitis, radiation pneumonia, malaise and myalgia. The incidence rate of grade 3-4 acute bone marrow suppression in NP group (8.7%, 2/23) was lower than that in TP group (38.5%, 10/26), and the difference was statistically significant ( χ2 = 4.35, P = 0.037). The incidence rate of myalgia in NP group (26.1%, 6/23) was lower than that in TP group (61.5%, 16/26), and the difference was statistically significant ( χ2 = 4.85, P = 0.028). Conclusions:Nab-P combined with cisplatin and concurrent radiotherapy has good efficacy in the treatment of patients with locally advanced esophageal squamous cell carcinoma, and the incidence rate of adverse reactions is lower than that of conventional paclitaxel combined with cisplatin and concurrent radiotherapy, so that the regimen is safe.

ABSTRACT

Objective:To explore the predictive value of thrombus markers for venous thromboembolism (VTE) in patients with malignant tumors after surgery.Methods:The clinical data of 150 patients with malignant tumors after surgery admitted to Cangzhou Hospital of Integrated Traditional Chinese Medicine and Western Medicine in Hebei Province from July 2020 to February 2021 were retrospectively analyzed. All 150 patients followed-up for 4 weeks were treated as the observation group, including 30 cases with VTE (the thrombosis group) and 120 cases without VTE (the non-thrombosis group). Another 60 cases undergoing healthy physical examination during the same period were selected as the control group. The chemiluminescence immunoassay was used to detect thrombin-antithrombin complex (TAT), plasmin-α 2 plasmin inhibitor complex (PIC), thrombomodulin (TM), tissue-type plasminogen activator inhibitor-1 complex(tPAIC). The control group was tested once, and the observation group was tested on the 1 day before the operation and 1 day after the operation. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of thrombus markers for VTE in patients with malignant tumors after surgery. Results:The patients with lung cancer ( χ2 = 12.53, P = 0.014), ≥ 60 years old ( χ2 = 6.66, P = 0.036),body mass index>30 kg/m 2 ( χ2 = 40.53, P<0.001), tumor metastasis ( χ2 = 5.38, P = 0.031), Ⅲ-Ⅳ stage ( χ2 = 5.83, P = 0.023) had higher incidence of VTE after the operation, and the difference was statistically significant. The levels of TAT, PIC and TM in the observation group were higher than those in the control group (all P < 0.05).The levels of TAT and TM in the thrombosis group were higher than those in the non-thrombosis group before the operation, and the difference was statistically significant (all P < 0.05).The value of TM in predicting VTE was high [the best cut-off value was 10.70 TU/ml, area under the curve (AUC) was 0.786, the sensitivity was 73.30%, the specificity was 81.70%], the combination of TAT and TM could improve the predictive value (AUC was 0.796, the sensitivity was 80.00%, the specificity was 77.50%). The levels of TAT, PIC, TM and tPAIC in thrombosis group were all higher than those in the non-thrombosis group after the operation, and the difference was statistically significant (all P < 0.05). The value of TAT in predicting VTE was high (the best cut-off value was 16.50 ng/ml, AUC was 0.887, the sensitivity was 82.36%, the specificity was 71.65%), the combination of TAT, PIC, TM and tPAIC could improve the predictive value (AUC was 0.913, the sensitivity was 90.00%, the specificity was 88.60%). The level of PIC was positively correlated with TAT before and after the operation ( r = 0.66, P < 0.001; r = 0.64, P < 0.001). Conclusions:TM can be used as a sensitive indicator in the early prediction of VTE for the patients with malignant tumors and it aims at the prevention; TAT can be used as a specific indicator in predicting the development of VTE and it aims at the intervention in time. The combined detection of TAT, PIC, TM and tPAIC can improve the predictive value of VTE. At the same time, PIC can be used to evaluate the risk of bleeding.

ABSTRACT

Objective:To compare the clinical efficacy of robot-assisted percutaneous screw implantation and free-hand open screw implantation by Wiltse approach in the treatment of thoracolumbar fracture.Methods:A retrospective cohort study was performed to analyze the clinical data of 71 patients with thoracolumbar fracture admitted to Second Affiliated Hospital of Soochow University from May 2018 to May 2020. There were 52 males and 19 females, with age range of 22-54 years[(41.0±7.8)years]. Of all, 33 patients were treated with robot-assisted percutaneous screw implantation (Group A) and 38 patients were treated with free-hand open screw implantation by Wiltse approach (Group B). Following parameters were measured, including frequency of radiation exposure, operation time, intraoperative blood loss, length of hospital stay, incidence of complications, rate of fracture healing at 3 months and 6 months postoperatively, visual analogue scale (VAS) and Oswestry dysfunction index (ODI) at 3 days, 3 months, 6 months postoperatively and at the last follow-up, anterior vertebral body height ratio and sagittal Cobb angle preoperatively, at 3 days postoperatively and at the last follow-up, and rate of screw implantation of grade A and B and rate of facet joint violation at 3 days postoperatively.Results:All patients were followed up for 10-24 months[(15.2±4.4)months]. Frequency of radiation exposure and operation time showed no statistical differences between the two groups (both P>0.05). Intraoperative blood loss was 100(100, 135)ml in Group A, less than 160(120, 200)ml in Group B ( P<0.01). Length of hospital stay was 8(7, 11) days in Group A, shorter than 12(10, 16)days in Group B ( P<0.01). There were no complications such as infection, spinal nerve injury or cerebrospinal fluid leakage in both group. There were no significant differences between the two groups in the rate of fracture healing at 3 and 6 months postoperatively (all P>0.05). VAS and ODI in Group A was 3(2, 4)points and 21(18, 23)points at 3 days postoperatively, lower than 4 (3, 5)points and 27(20, 32)points in Group B ( P<0.05 or 0.01), and the two groups showed no significant differences in VAS and ODI at other time points (all P>0.05). There were no significant difference in the anterior vertebral body height ratio or sagittal Cobb angle between the two groups at 3 days postoperatively and at the last follow-up (all P>0.05). Rate of screw implantation of grade A and B was 96.5% (191/198) in Group A, higher than 90.4% (206/228) in Group B ( P<0.05). Rate of facet joint violation was 4.0%(8/198) in Group A, lower than 11.8% (27/228) in Group B ( P<0.01). Conclusion:For thoracolumbar fracture, robot-assisted percutaneous screw implantation is superior to free-hand open screw implantation by Wiltse approach in terms of less bleeding, shorter hospitalization, earlier pain alleviation, higher accuracy of screw implantation and lower risk of facet joint violation.

ABSTRACT

Objective:To investigate the clinical efficacy of pancreaticoduodenectomy with TRIANGLE operation in the treatment of pancreatic head cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 51 patients with pancreatic head cancer who were admitted to the Sichuan Provincial People′s Hospital, Affiliated Hospital of School of Medicine of University of Electronic Science and Technology of China from January 2017 to July 2018 were collected. There were 33 males and 18 females, aged from 42 to 74 years, with a median age of 56 years. Of the 51 patients, 24 cases undergoing standard pancreaticoduodenectomy, in which No.12, 13 and 17 lymph nodes were dissected, combined with transcatheter arterial infusion chemo-therapy (TAI) were allocated into the standard group, and 27 cases undergoing pancreaticoduo-denectomy with TRIANGLE operation, in which No.7, 8, 9, 12, 13, 16, 17 lymph nodes were dissected, combined with TAI were allocated into the TRIANGLE group, respectively. Observation indicators: (1) intraoperative conditions of the two groups; (2) postoperative conditions of the two groups; (3) follow-up and survival. Follow-up was conducted using outpatient examination and telephone interview once three months to detect tumor recurrence and metastasis and survival of patients up to July 2021 or the death of patient. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the chi-square test or the Fisher exact probability. Comparison of ordinal data was analyzed using the rank sum test. Kaplan‐Meier method was used to calculate the survival rate and median survival time and draw survival curve. Log‐Rank test was used for survival analysis. Results:(1) Comparison of intraoperative conditions between the two groups. The operation time, volume of intraoperative blood loss, cases with intraoperative blood transfusion were (501±61)minutes, (563±278)mL, 4 in the standard group, versus (556±46)minutes, (489±234)mL, 6 in the TRIANGLE group, respectively. There was a significant difference in the operation time between the two groups ( t=3.62, P<0.05) but there was no significant difference in the volume of intraoperative blood loss or cases with intraoperative blood transfusion between the two groups ( t=1.03, χ2=0.25, P>0.05). (2) Comparison of postoperative conditions between the two groups. Of the 51 patients, 30 had 50 times of postoperative complications, including 18 times of grade Ⅰ complications of Clavien-Dindo classification, 29 times of grade Ⅱ complications of Clavien-Dindo classification, 2 times of grade Ⅲa complications of Clavien-Dindo classification, 1 time of grade Ⅲb complications of Clavien-Dindo classification, respectively. Cases with postoperative complications, cases with delayed gastric emptying, cases without or with pancreatic fistula as class A or class B, cases with biliary fistula, cases with bleeding, cases with diarrhea were 15, 4, 13, 7, 4, 4, 2, 2 in the standard group, versus 15, 6, 14, 10, 3, 4, 1, 3 in the TRIANGLE group, respectively. There was no significant difference in cases with postoperative complications, cases with delayed gastric emptying, cases with pancreatic fistula between the two groups ( χ2=0.16, 0.02, Z=-0.04, P>0.05) and there was no significant difference in cases with biliary fistula, cases with bleeding, cases with diarrhea between the two groups ( P>0.05). Cases with complications as Clavien-Dindo grade Ⅰ, grade Ⅱ, grade Ⅲ were 10, 11, 2 in the standard group, versus 8, 18, 1 in the TRIANGLE group, showing no significant difference between the two groups ( Z=-0.67, P>0.05). The duration of postoperative hospital stay was (23±8)days in both of the standard group and the TRIANGLE group, showing no significant difference between the two groups ( t=0.31, P>0.05). (3) Follow-up and survival. All the 51 patients were followed-up for 6 to 54 months, with a median follow-up time of 17 months. The postoperative 1-year overall survival rate was 75.0% and 81.5% in the standard group and the TRIANGLE group, respectively. The postoperative 3-year overall survival rate was 12.5% and 22.2% in the standard group and the TRIANGLE group, respectively. The median postoperative survival time was 15.00 months (95% confidence interval as 12.63 to 17.37 months) and 21.00 months (95% confidence interval as 15.91 to 19.62 months) in the standard group and the TRIANGLE group, respectively. There was a significant difference in survival of patients between the two groups ( χ2=4.30, P<0.05). Cases with tumor recurrence during post-operative 1 year and 3 year were 9 and 20 in the standard group, versus 6 and 15 in the TRIANGLE group, respectively. There was no significant difference in cases with tumor recurrence during postoperative 1 year between the two groups ( P>0.05) and there was a significant difference in cases with tumor recurrence during postoperative 3 year between the two groups ( P<0.05). Conclusion:Compared with standard pancreaticoduodenectomy, pancreaticoduodenectomy with TRIANGLE operation can prolong the median survival time of patients with pancreatic head cancer without increasing surgical related complications.

ABSTRACT

Objective:To investigate the predictive value of baseline peripheral blood neutrophil to lymphocyte ratio (NLR), National Institutes of Health Stroke Scale (NIHSS) score combined with collateral circulation Tan score for the outcome of intravenous thrombolysis in patients with acute anterior circulation large vessel occlusive stroke.Methods:Patients with acute anterior circulation large vessel occlusive stroke received alteplase intravenous thrombolysis in the Departmet of Neurology, the Second Affiliated Hospital of Anhui Medical University from January 2019 to May 2021 were enrolled retrospectively. The modified Rankin Scale score was used to evaluate the outcomes at 90 d after thrombolysis. 0-2 was defined as good outcome and 3-6 were defined as poor outcome. The demographics, clinical data and imaging data between the good outcome group and the poor outcome group were compared. Multivariate logistic regression analysis was used to determine the independent influencing factors of the outcome of thrombolysis, and the receiver operating characteristic (ROC) curve was used to analyze the predictive value of NLR, NIHSS score, Tan score and their combination on the outcome of intravenous thrombolysis. Results:A total of 118 patients with acute anterior circulation large vessel occlusive stroke were enrolled during the study. Their age was 67.73±11.91 years, and there were 71 males (60.2%). Fifty-eight patients (49.2%) were in the good outcome group and 60 (50.8%) were in the poor outcome group. Univariate analysis showed that there were significant differences in NLR, collateral circulation Tan score and baseline NIHSS score between the good outcome group and the poor outcome group (all P<0.05). Multivariate logistic regression analysis showed that NLR (odds ratio [ OR] 1.299, 95% confidence interval [ CI] 1.005-1.679; P=0.046), baseline NIHSS score ( OR 1.150, 95% CI 1.037-1.275; P=0.008), collateral circulation Tan score ( OR 0.298, 95% CI 0.160-0.556; P<0.001) were independently associated with the outcomes. ROC curve analysis showed that the areas under the curve of NLR, baseline NIHSS score, Tan score and their combination for predicting poor outcome were 0.640, 0.752, 0.823 and 0.870, respectively. Conclusions:Peripheral blood NLR before thrombolysis, baseline NIHSS score and collateral circulation Tan score could predict the outcomes after intravenous thrombolysis in patients with acute anterior circulation large vessel occlusive stroke, and the combination of the three had a higher predictive value.

ABSTRACT

ObjectiveTo study the conceptual framework and methodological system of the International Classification of Functioning, Disability and Health (ICF) in occupational therapy and its systematic implementation in clinical practice. MethodsBased on the ICF theory and the policy documents of the World Federation of Occupational Therapists, the conceptual framework of occupational therapy and the systematic implementation in clinical settings based on the ICF framework were analyzed. ResultsThis study constructed a conceptual framework and approach for occupational therapy based on ICF, and clarified the goals, principles, and implementation methods of integrated occupational therapy interventions in rehabilitation services. The goal of occupational therapy interventions was to improve the individual activity and participation through multidisciplinary and cross-cutting implementation of integrated occupational therapy programs to optimize functioning. Occupational therapy was based on the bio-psycho-social model, adhered to the principles of person-centeredness and functioning orientation, and implemented individualized intervention programs in different context. In clinical practice, it was recommended to follow ICF-based standardized process and systematically use World Health Organization Family International Classifications: functioning and unmet needs analysis using ICHI; functional classification, assessment and coding using ICF; disease classification, diagnosis and coding using ICD; intervention of occupational therapies using ICHI to build a systematic occupational therapy service system. ConclusionAn ICF-based occupational therapy concept and methodological system has been built, a comprehensive clinical occupational therapy implementation model has been established, the goal of activity and participation oriented occupational therapy interventions has been clarified, and the systematic, structured, standardized and refined level of occupational therapy has been enhanced.

ABSTRACT

Anti-CD19 chimeric antigen receptor (CAR) T cell therapy has shown impressive efficacy in treating B-cell malignancies. A single-center phase I dose-escalation study was conducted to evaluate the safety and efficacy of T cells transduced with CBM.CD19 CAR, a second-generation anti-CD19 CAR bearing 4-1BB costimulatory molecule, for the treatment of patients with refractory diffuse large B-cell lymphoma (DLBCL). Ten heavily treated patients with refractory DLBCL were given CBM.CD19 CAR-T cell (C-CAR011) treatment. The overall response rate was 20% and 50% at 4 and 12 weeks after the infusion of C-CAR011, respectively, and the disease control rate was 60% at 12 weeks after infusion. Treatment-emergent adverse events occurred in all patients. The incidence of cytokine release syndrome in all grades and grade ⩾ 3 was 90% and 0, respectively, which is consistent with the safety profile of axicabtagene ciloleucel and tisagenlecleucel. Neurotoxicity or other dose-limiting toxicities was not observed in any dose cohort of C-CAR011 therapy. Antitumor efficacy was apparent across dose cohorts. Therefore, C-CAR011 is a safe and effective therapeutic option for Chinese patients with refractory DLBCL, and further large-scale clinical trials are warranted.

ABSTRACT

Objective:To observe the effect of early mechanical ventilation on the expression of inflammatory factors and prognosis of patients with severe traumatic brain injury (sTBI).Methods:From January 2017 to December 2020, 138 patients with sTBI admitted to the department of the emergency of Xinhua Hospital Chongming Branch were enrolled. Although some patients were admitted to hospital without acute respiratory failure, their Glasgow coma score (GCS) were less than 8, they bad risk of hypoxia, so early mechanical ventilation was required. According to the patient's condition and the willingness of family members, patients were divided into mechanical ventilation group (tracheal intubation mechanical ventilation) and conventional oxygen inhalation group (nasal catheter or mask oxygen inhalation) in the end. The arterial partial pressure of oxygen (PaO 2), arterial partial pressure of carbon dioxide (PaCO 2), oxygenation index (PaO 2/FiO 2), tumor necrosis factor-α (TNF-α), and interleukin (IL-6, IL-10) levels at admission, preoperation and 72 hours postoperation, as well as GCS before operation and 1 week after operation, the duration and number of patients successfully evacuated from the ventilator within 1 week after surgery were observed and analyzed. Results:A total of 138 sTBI patients were enrolled in the study, including 72 cases in the mechanical ventilation group and 66 cases in the routine oxygen inhalation group. In the two groups, PaO 2, PaO 2/FiO 2 and IL-10 were higher, and PaCO 2, TNF-αand IL-6 were lower at 72 hours post operation than that before operation. Moreover, the changes in the mechanical ventilation group were more significant than those in the conventional oxygen inhalation group [PaO 2 (1 mmHg = 0.133 kPa): 94.6±7.7 vs. 92.5±6.8, PaO 2/FiO 2 (mmHg): 351±94 vs. 319±89, IL-10 (ng/L): 8.2±2.7 vs. 7.4±1.8, PaCO 2 (mmHg): 35.6±1.8 vs. 37.5±2.7, TNF-α(ng/L): 71.5±6.3 vs. 96.8±15.5, IL-6 (ng/L): 10.8±3.9 vs. 14.4±6.5, all P < 0.05]. There were 17 patients with severe respiratory insufficiency or failure in the conventional oxygen inhalation group before operation. Compared with the conventional oxygen inhalation group, the GCS score (11.7±3.1 vs. 9.1±4.6) and the proportion of successful weaning [62.5% (45/72) vs. 44.0% (29/66)] were significantly higher, and the duration of successful weaning (hours: 63.5±28.6 vs. 88.1±33.9) was significantly shorter in the mechanical ventilation group 1 week after operation. Conclusion:Early mechanical ventilation in sTBI patients can significantly improve oxygen supply, inhibit the release of pro-inflammatory factors, reduce secondary brain damage, and effectively improve the prognosis.

ABSTRACT

Objective:To analyze rehabilitation of functioning of mobility for critically ill patients based on the framework of the World Health Organization Family International Classifications (WHO-FICs). Methods:A scoping review of rehabilitation of functioning of mobility for critically ill patients had been conducted. Literatures on early mobilization or rehabilitation in the field of critical illness from databases of Web of Science, PubMed, CNKI, and Wanfang up to February 28, 2021 were retrieved. The diseases, functioning, rehabilitation intervention, functioning evaluation and environment of patients in critical ward had been reviewed. Results:Based on WHO-FICs framework, this paper reviewed literatures in five dimensions: the type of diseases, functioning, rehabilitation intervention, functioning evaluation and environment factors. The diseases included respiratory system diseases (MD10-MD6Y), neurological system diseases (MB40-MB9Y), cardiovascular system diseases (MC80-MC9Y), post-surgical (MD80-ME4Y, ME60-ME6Y, ME80-MF1Y), and others (NA00-NF2Z, MA00-MA3Y, 1G40-1G41). The functioning included movement-related structures (s720-s760), neuromusculoskeletal and movement-related functions (b710-b740), mobility (d4), self-care (d5), and remunerative employment (d850). The rehabilitation interventions were divided into three categories based on the International Classification of Health Interventions (ICHI) β-3: therapeutic, preventive, and health promotion interventions. The evaluation of functioning mainly involved joint mobility, muscle strength, muscle tone, de Morton Mobility Index, Functional Status Score for Intensive Care Unit (FSS-ICU), 6-Minute Walking Test (6WMT), intensive care unit (ICU) length of stay and so on. The intensive care environment was also discussed using ICF environment factors. Conclusion:This paper proposed a framework of rehabilitation of mobility for critically ill patients based on the WHO-FICs. It focused on respiratory system disease, neurological system diseases, cardiovascular system diseases, post-surgical with mobility dysfunction. To implement interventions in therapeutic, preventive, and health promotion to optimize patients' function, and to prevent complications and secondary dysfunction, and improve their well-being.

ABSTRACT

@#With the broad application of high-resolution computed tomography (CT) and high rates of early lung cancer screening, the number of patients diagnosed with synchronous multiple primary lung cancer (sMPLC) has been increasing. It becomes of great prominence to distinct sMPLC from intrapulmonary metastases in clinical practice. An increasing number of studies have developed high-throughput sequencing based genetic approaches to specify the molecular characteristics of sMPLC, which contributes to a better understanding of its tumorigenesis. The genetic profile of sMPLC also benefits its diagnosis, which mainly relies on its clinicopathological criteria. Here, we summarize the progresses on the diagnostic criteria for sMPLC, and also molecular features of sMPLC from the perspective of clonality analysis.
