ABSTRACT
Objective:To analyze the value of alpha-fetoprotein(AFP) in predicting survival of patients who underwent salvage surgery after tumor downstaging therapy in patients with advanced hepatocellular carcinoma.Methods:The data of 50 patients with Barcelona Clinic Liver Cancer Staging (BCLC) C hepatocellular carcinoma treated at the Faculty of Hepato-Pancreato-Biliary Surgery, Chinese PLA General Hospital from December 2018 to December 2021 were collected. There were 45 males and 5 females, with the age of (53.0±10.5) years. The patients were divided into two groups based on the serum AFP level after tumor downstaging therapy, AFP normal group ( n=27, AFP≤20 μg/L) and the control group ( n=23, AFP>20 μg/L). Patient survival and tumor recurrence were followed up by outpatient review or telephone follow-up. The survival rate was calculated by the Kaplan-Meier method and compared by the log-rank test. The efficacy of combined immunotargeted therapy were compared between the two groups. Univariate and multivariate Cox regression analysis were carried to analyse the factors influcing prognosis. Results:The median survival time was not reached in both groups. The 1-year and 2-year cumulative survival rates were 95.0% and 88.2% in the normal group and 73.4% and 54.1% in the control group, respectively. The median relapse-free survival time of the normal group was not reached, and the median relapse-free survival time of the control group was 11 months. The 1-year recurrence-free survival rate was 78.1% in the normal group and 39.5% in the control group. The cumulative survival rate and relapse-free survival rate in the normal group were significantly higher than those in the control group (χ 2=7.60, 8.83, P=0.006, 0.003). The complete response, partial response and pathological complete response of tumors in the normal group were significant better than those in the control group. Multivariate Cox regression analysis showed that patients with serum AFP >20 μg/L ( HR=2.952, 95% CI: 1.023-8.517, P=0.045) after immunotherapy combined with targeted therapy had an increased risk of postoperative recurrence. Conclusion:The reduction of serum AFP to normal after downstaging therapy could be used as a prognostic indicator of salvage surgical in patients with BCLC C hepatocellular carcinoma, and AFP was related to the efficacy of downstaging therapy in patients.
ABSTRACT
Background@#and Purpose Intravenous tenecteplase (TNK) efficacy has not been well demonstrated in acute ischemic stroke (AIS) beyond 4.5 hours after onset. This study aimed to determine the effect of intravenous TNK for AIS within 4.5 to 24 hours of onset. @*Methods@#In this pilot trial, eligible AIS patients with diffusion-weighted imaging (DWI)-fluid attenuated inversion recovery (FLAIR) mismatch were randomly allocated to intravenous TNK (0.25 mg/kg) or standard care within 4.5–24 hours of onset. The primary endpoint was excellent functional outcome at 90 days (modified Rankin Scale [mRS] score of 0–1). The primary safety endpoint was symptomatic intracranial hemorrhage (sICH). @*Results@#Of the randomly assigned 80 patients, the primary endpoint occurred in 52.5% (21/40) of TNK group and 50.0% (20/40) of control group, with no significant difference (unadjusted odds ratio, 1.11; 95% confidence interval 0.46–2.66; P=0.82). More early neurological improvement occurred in TNK group than in control group (11 vs. 3, P=0.03), but no significant differences were found in other secondary endpoints, such as mRS 0–2 at 90 days, shift analysis of mRS at 90 days, and change in National Institutes of Health Stroke Scale score at 24 hours and 7 days. There were no cases of sICH in this trial; however, asymptomatic intracranial hemorrhage occurred in 3 of the 40 patients (7.5%) in the TNK group. @*Conclusion@#This phase 2, randomized, multicenter study suggests that intravenous TNK within 4.5–24 hours of onset may be safe and feasible in AIS patients with a DWI-FLAIR mismatch.

ABSTRACT
Objective: To examine the value of intravascular ultrasound (IVUS) for excimer laser ablation (ELA) combined with drug-coated balloon (DCB) in treating lower limb arteriosclerotic obliterans (ASO). Methods: As a prospective case series study, patients who underwent ELA combined with DCB for lower limb ASO with the guidance of IVUS from September 2021 to March 2022 at Department of Vascular Surgery, Zhongshan Hospital, Fudan University were enrolled prospectively. Lesion characteristics, procedure-related outcomes and complications were collected. The therapy outcomes were compared with baseline data by paired t test. Results: There were 8 males and 2 females, aged (72.0±5.9) years (range: 61 to 81 years). Of all the 11 lesions, there were 8 lesions in superficial femoral artery and 3 in popliteal artery. The lesion length was (7.0±2.4) cm (range: 3.2 to 9.8 cm). There were 4 chronic totally occlusion and 7 severe stenosis. All patients underwent the operation successfully. The technical success rate was 10/11. Bailout stenting was performed in one lesion because of flow-limiting dissection. Four lesions were grade 3 to 4 in peripheral artery calcium score system, and 9 lesions with calcification arc≥180°. Larger diameter drug-coated balloons were selected in 5 lesions after measurement of intravascular ultrasound. The follow-up time was (6.0±1.9) months (range: 3 to 9 months). The ankle-brachial index of the patient was significantly improved immediately after surgery (0.97±0.13 vs. 0.48±0.18, t=-7.60, P<0.01) and at 3 months after surgery (0.95±0.12 vs. 0.48±0.18, t=-7.17, P<0.01). The 3-month primary patency rate was 11/11, the target lesion reintervention was 0 and ulcer healing rate was 3/4. Conclusion: IVUS assisted ELA in the treatment of lower limb artery lesions is safe and effective in early stage.

Objective: To evaluate treatment responses, outcomes, and prognostic factors in adults with secondary acute myeloid leukemia (sAML) . Methods: Between January 2008 and February 2021, date of consecutive cases of younger than 65 years of adults with sAML were assessed retrospectively. Clinical characteristics at diagnosis, treatment responses, recurrence, and survival were evaluated. Logistic regression and Cox proportional hazards model were employed to determine significant prognostic indicators for treatment response and survival. Results: 155 patients were recruited, including 38, 46, 57, 14 patients belonging to t-AML, and AML with unexplained cytopenia, post-MDS-AML, and post-MPN-AML, respectively. In the 152 evaluable patients, the rate of MLFS after the initial induction regimen was 47.4%, 57.9%, 54.3%, 40.0%, and 23.1% in the four groups (P=0.076) . The total rate of MLFS after the induction regimen was 63.8%, 73.3%, 69.6%, 58.2%, and 38.5% (P=0.084) , respectively. Multivariate analysis demonstrated that male gender (OR=0.4, 95% CI 0.2-0.9, P=0.038 and OR=0.3, 95% CI 0.1-0.8, P=0.015) , SWOG cytogenetic classification into unfavorable or intermediate (OR=0.1, 95% CI 0.1-0.6, P=0.014 and OR=0.1, 95% CI 0.1-0.3, P=0.004) and receiving low-intensity regimen as induction regimen (OR=0.1, 95% CI 0.1-0.3, P=0.003 and OR=0.1, 95%CI 0.1-0.2, P=0.001) were typical adverse factors impacting the first CR and the final CR; PLT<45 × 10(9)/L (OR=0.4, 95%CI 0.2-0.9, P=0.038) and LDH ≥258 U/L (OR=0.3, 95%CI 0.1-0.7, P=0.005) were independent factors for CR. Among the 94 patients with achieving MLFS, 46 cases had allogeneic hematopoietic stem cell transplantation. With a median follow-up period of 18.6 months, the probabilities of relapse-free survival (RFS) and overall survival (OS) at 3 years were 25.4% and 37.3% in patients with transplantation, and in patients with chemotherapy, the probabilities of RFS and OS at 3-year were 58.2% and 64.3%, respectively. At the time of achieving MLFS, multivariate analysis revealed that age ≥46 years (HR=3.4, 95%CI 1.6-7.2, P=0.002 and HR=2.5, 95%CI 1.1-6.0, P=0.037) , peripheral blasts ≥17.5% at diagnosis (HR=2.5, 95%CI 1.2-4.9, P=0.010 and HR=4.1, 95%CI 1.7-9.7, P=0.002) , monosomal karyotypes (HR=4.9, 95%CI 1.2-19.9, P=0.027 and HR=28.3, 95%CI 4.2-189.5, P=0.001) were typical adverse factors influencing RFS and OS. Furthermore, CR after induction chemotherapy (HR=0.4, 95%CI 0.2-0.8, P=0.015) and transplantation (HR=0.4, 95%CI 0.2-0.9, P=0.028) were substantially linked to longer RFS. Conclusion: Post-MDS-AML and post-MPN-AML had lower response rates and poorer prognoses than t-AML and AML with unexplained cytopenia. In adults with male gender, low platelet count, high LDH, and SWOG cytogenetic classification into unfavorable or intermediate at diagnosis, and receiving low-intensity regimen as the induction regimen predicted a low response rate. Age ≥46 years, a higher proportion of peripheral blasts and monosomal karyotype had a negative effect on the overall outcome. Transplantation and CR after induction chemotherapy were greatly linked to longer RFS.

Objective:To observe the occurrence of epithelial-mesenchymal transition (EMT) in cervical cancer cell line Siha irradiated by X-rays with clinical conventional fraction radiotherapy model and investigate the role of exosomes in this process.Methods:Siha cells were irradiated by 6 MV-X rays with 50 Gy in 25 fractions. EMT was evaluated by cell morphology, EMT biomarkers and cell migration and invasion ability. Exosomes released from cells were detected by transmission electron microscopy and nanoparticle tracking analysis (NTA), and its function in EMT was explored by using an exosome inhibitor GW4869 (10 μmol/L).Results:After irradiation, EMT phenomenon was induced in the survived Siha cells, including the incidence of mesenchymal phenotype, upregulation of epithelial marker E-cadherin ( t=9.66, P<0.05), downregulation of mesenchymal marker N-cadherin ( t=41.61, P<0.05), and increase of cell migration and invasion abilities ( t=6.11, 13.22; P<0.05). Meanwhile, the secretion of exosomes was also increased after irradiation ( t=7.51, P<0.05). When the cells were pre-treated with GW4869, radiation-induced exosome secretion was reduced ( t=7.28, P<0.05), so that radiation-induced EMT was reversed. Conclusions:Ionizing radiation with clinical conventional fraction radiotherapy model promotes EMT of cervical cancer cells through increasing the secretion of exosomes.
ABSTRACT
Objective:To evaluate the efficacy and safety of apatinib in combination with chemoradiotherapy for head and neck squamous cell carcinoma (HNSCC).Methods:37 patients orally received apatinib at 250 mg/d during concurrent chemoradiotherapy until completion of radiotherapy, complete remission assessed by imaging examination, the onset of unacceptable toxicity or death. Baseline characteristics, objective response rates (ORR) and adverse events were assessed in all enrolled patients with complete baseline and safety data. Progression-free survival (PFS) and overall survival (OS) were calculated by Kaplan-Meier method. Prognostic factors were statistically identified using Cox regression models.Results:The ORR was 85%(95% CI: 72%-98%). The median PFS was 17.9 months and the 2-year OS rate was 62%(95% CI: 48%-80%). Ineffective short-term efficacy ( HR=0.035, 995% CI: 0.02-0.652, P=0.025) was an independent risk factor for poor OS. In addition, ineffective short-term efficacy ( HR=0.104, 95% CI: 0.017-0.633, P=0.014) and lymphocytopenia ( HR=17.539, 95% CI: 2.040-150.779, P=0.009) were independent risk factors for poor PFS. Common adverse events (>60%) included lymphocytopenia (76%), leukopenia (68%) and irradiation-induced mucosal injury (65%). The most common treatment-associated grade 3 adverse event was lymphopenia (49%). Conclusions:Apatinib combined with chemoradiotherapy yield significant anti-tumor activity for HNSCC with controllable toxicity. For patients with advanced HNSCC, short-term efficacy and lymphocytopenia may be potential predictors for clinical efficacy of apatinib combined with chemoradiotherapy.
ABSTRACT
Objective: To explore the safety and short-term efficacy of venetoclax combined with azacitidine (Ven+AZA) in previously untreated patients unfit for standard chemotherapy and patients with relapsed/refractory (R/R) acute myeloid leukemia (AML) in China. Methods: A retrospective study was conducted in 60 previously untreated patients unfit for standard chemotherapy and patients with R/R AML who received Ven+ AZA (venetoclax, 100 mg D1, 200 mg D2, 400 mg D3-28; azacitidine, 75 mg/m(2) D1- 7) at the Peking University Institute of Hematology from June 1, 2019 to May 31, 2021. The incidence of adverse events, complete remission (CR) /CR with incomplete hematological recovery (CRi) rate, objective remission rate (ORR) , and minimal residual disease (MRD) status in patients with different risk stratification and gene subtypes were analyzed. Results: The median age of the patients was 54 (18-77) years, 33 (55.0%) were males, and the median follow-up time was 4.8 (1.4-26.3) months. Among the 60 patients, 24 (40.0%) were previously untreated patients unfit for standard chemotherapy, and 36 (60.0%) were R/R patients. The median mumber cycles of Ven+AZA in the two groups were both 1 (1-5) . According to the prognostic risk stratification of the National Comprehensive Cancer Network, it was divided into 8 cases of favorable-risk, 2 cases of intermediate risk, and 14 cases of poor-risk. In previously untreated patients unfit for standard chemotherapy, after the first cycle of Ven+AZA, 17/24 (70.8%) cases achieved CR/CRi, 3/24 (12.5%) achieved partial remission (PR) , and the ORR was 83.3%. Among them, nine patients received a second cycle chemotherapy and two received a third cycle. Among CR/CRi patients, 8/17 (47.1%) achieved MRD negativity after two cycles of therapy. In the R/R group, after the first cycle of Ven+AZA, 21/36 (58.3%) cases achieved CR/CRi (7/21 achieved MRD negativity) , 3 achieved PR, and the ORR was 66.7%. Among R/R patients, 12 were treated for more than two cycles. There were no new CR/CRi patients after the second treatment cycle, and 14 cases (66.7%) achieved MRD negativity. According to the time from CR to hematological recurrence, the R/R group was divided into 12 cases in the favorable-risk group (CR to hematological recurrence ≥18 months) and 24 in the poor-risk group (CR to hematological recurrence<18 months, no remission after one cycle of therapy, and no remission after two or more cycles of therapy) . Eleven of 24 (45.8%) cases achieved CR/CRi after one cycle of Ven+AZA in the poor-risk R/R group, and 10 of 12 (83.3%) achieved CR/CRi in the favorable-risk R/R group, which was significantly superior to the poor-risk group (P=0.031) . After one cycle of treatment, 13 patients with IDH1/2 mutations and 4 that were TP53-positive all achieved CR/CRi. The CR/CRi rate of 18 patients with NPM1 mutations was 77.8%. Five patients with RUNX1-RUNX1T1 combined with KIT D816 mutation (two initial diagnoses and three recurrences) had no remission. Ven+ AZA was tolerable for AML patients. Conclusion: Ven+AZA has acceptable safety in previously untreated patients unfit for standard chemotherapy, patients with R/R AML can achieve a high response rate, and some patients can achieve MRD negativity. It is also effective in NPM1-, IDH1/IDH2-, and TP53-positive patients. The long-term efficacy remains to be observed.

Objective:To detect the expression and clinical significance of microRNA-128-3p (miR-128-3p) in the plasma of patients with severe pancreatitis (SAP) .Methods:A total of 175 patients with acute pancreatitis who were treated in our hospital from Jun. 2017 to Dec. 2020 were selected as observation objects. According to the severity of the patients, the patients were divided into 78 cases in mild acute pancreatitis (MAP) group, 50 cases in moderate to severe acute pancreatitis (MSAP) group and 47 cases in severe acute pancreatitis (SAP) group; according to the patient’s prognosis, the SAP group was divided into 28 cases in the survival group and 19 cases in the death group. The level of miR-128-3p was detected by qRT-PCR method, and patients were evaluated with Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score and Ranson score, the correlation between plasma miR-128-3p level and APACHEⅡ, Ranson score was analyzed by Pearson, the predictive value of plasma miR-128-3p for poor prognosis of SAP patients was analyzed by ROC curve.Results:There were statistically significant differences in APACHE II[ (3.41±1.56) , (5.63±1.78) , (6.57±1.83) points], Ranson [ (2.58±1.34) , (4.95±1.47) , (6.06±1.92) points] and plasma CRP [ (39.73) ±12.31) , (70.25± 24.38) , (142.51±40.55) mg/L], serum calcium [ (1.95±0.31) , (13.26±5.24) , (14.21±6.32) mmol/L], among the MAP group, MSAP group and SAP group ( P<0.05) ; Compared with the MAP group (1.05±0.12) , the plasma miR-128-3p expression levels in the MSAP group (0.83±0.08) and the SAP group (0.57±0.05) were significantly decreased ( P<0.05) ; compared with the MSAP group (0.83±0.08) Compared with the SAP group (0.57±0.05) , the plasma miR-128-3p expression level was significantly decreased ( P<0.05) ; Compared with the survival group [ (0.65±0.08) , (5.91±1.64) points, (5.45±1.25) points, (120.43±30.56) mg/L], the plasma miR-128-3p of SAP patients in the death group was (0.43±0.05) expression levels were significantly reduced, APACHE II [ (7.43±2.21) points], Ranson score [ (7.22±1.59) points] and plasma CRP level [ (171.52±42.38) mg/L] were significantly increased ( P<0.05) ; the results of correlation analysis showed that plasma miR-128-3p level was negatively correlated with APACHEⅡ and Ranson scores ( r=-0.531, -0.609, P<0.05) ; The diagnostic efficacy of plasma miR-128-3p in predicting poor prognosis of SAP patients is better than APACHEⅡ, Ranson score, and CRP. Conclusion:Plasma miR-128-3p level is elevated in patients with severe pancreatitis, which is of certain value for the diagnosis and prognostic evaluation of SAP.
ABSTRACT
Objective:To construct and validate prognostic nomograms predicting overall survival (OS) and cancer-specific survival (CSS) of patients with late-stage hepatocellular carcinoma (HCC).Methods:A retrospective cohort study was used in this report. Screened 2382 late-stage HCC patients obtained from Surveillance, Epidemiology, and End Results (SEER) database (2010—2015), were randomly classified into the training cohort and the internal validation cohort by using the function in R software according to the ratio of 1∶1. Chi-square test was applied to verify the comparability of data between two groups. The external validation cohort ( n=62) were collected from the Affiliated Zhangjiagang Hospital of Soochow University. Based on univariate and multivariate COX regression analyses in the training cohort, this study constructed nomograms for 6- and 12- month OS and CSS. Concordance index (C-index), calibration plots, the receiver operating characteristic (ROC) curves and Kaplan-Meier survival curves were applied to measure the performance of nomograms in the training cohort and to validate nomograms in two validation cohorts. The clinical utility was measured by decision curve analysis (DCA). Results:Two nomograms were constructed. The identified risk factors included sex, Edmondson-Steiner grade, T stage, N stage, M stage, tumor size, bone metastasis, Alpha-fetoprotein (AFP), surgery of primary site, radiation and chemotherapy. The C-index for OS in the training and two validation cohorts was 0.729(95% CI: 0.711-0.747), 0.721(95% CI: 0.705-0.737) and 0.860(95 CI: 0.831-0.889), respectively. The C-index for CSS in the training and two validation cohorts was 0.732(95% CI: 0.714-0.750), 0.725(95% CI: 0.707-0.743) and 0.862(95% CI: 0.829-0.895), respectively. Afterwards, for nomograms in the training and two validation cohorts, C-index and calibration plots expressed great predictive accuracy and concordance. ROC curves and Kaplan-Meier survival curves demonstrated good prognostic ability. Furthermore, nomograms performed superior to other models. DCA showed substantial clinical utility. Conclusion:This study has developed and validated nomograms predicting 6- and 12- month OS and CSS of patients with late-stage HCC, which may be useful to develop the individualized treatment.
ABSTRACT
This study systematically combed and analyzed the use of such terms as "prohibition"， "contraindication"， and "use with caution" in ancient Chinese books on materia medica and prescriptions， Pharmacopoeia of the People's Republic of China（《中华人民共和国药典》）， and teaching materials and monographs of Chinese materia medica by means of hermeneutics， commentariology， textology， and data mining， and explored the historical evolution and conceptual connotations of "prohibition"， "contraindication"， and "use with caution" in Chinese materia medica， so as to provide reference for standardizing their understandings and clinical reasonable medication. The "prohibition"， "contraindication"， and "use with caution" of Chinese materia medica were first proposed in the period of pre-Qin and Han dynasties. "Prohibition" and "contraindication" were separately developed in the Sui， Tang， and Five dynasties and Song， Jin， and Yuan dynasties and have been widely used since the Ming and Qing dynasties. The "use with caution" becomes popular rapidly in modern times and is often present in clinical medication together with "prohibition" and "contraindication". "Prohibition" basically means strictly prohibited and "contraindication" means to avoid as much as possible. The terms "prohibition"， "contraindication"， and "use with caution" have experienced evolution from the pre-Qin period to modern times， and they are used to describe the degree of restriction on drug use（"prohibition" > " contraindication" > "use with caution"）.
ABSTRACT
Objective:To evaluate the effect of motor imagery training on motor and executive function in the older population. Methods:Articles about the impact of motor imagery training on the motor and cognitive functions of the elderly in the databases of Web of Sciences, PubMed, CNKI, Wanfang data and VIP were searched from 1980 to 2020. The training program, rehabilitation effect and relatec factors of motor image training in the elderly were analyzed and summarized. Results:Twelve articles were included finally. The motor image training that suited the elderly over 60 years old was usually combined with actual exercise training, mostly for four to twelve weeks, two to three times a week and 15 to 60 minutes a time. Motor imagery training was effective on standing balance, postural control, falls and muscle strength, to improve the ability to solve conflict problems, working memory and cognitive flexibility. Conclusion:Motor imagery training is an effective way to delay the decline of physical function and improve the executive function of the elderly. It is needed to construct a reasonable and standard motor imagery training program according to the characteristics of the elderly, to improve the effect.
ABSTRACT
Objective To analyze the effect of physical activity intervention on the cognitive and neural functions of attention deficit hyperactivity disorder (ADHD) children. Methods Literatures related to physical activity intervention and functional rehabilitation of ADHD children in PubMed, EMBASE, Web of Science, CNKI and Wanfang data were searched from January, 1990 to July, 2021. The authors, countries, publication time, subjects and ages, research methods, intervention methods, measurement tools, results and conclusions of the included literatures were extracted. Based on the theory of the International Classification of Functioning, Disability and Health (Children and Adolescents Version) (ICF-CY), the terminology and research framework were established to systematically analyze physical activity intervention programs and intervention effects in the cognitive neural function of ADHD children. Results A total of 1995 literatures were returned, twelve of them were finally included. These studies came from six countries, mainly from clinical medicine, sports rehabilitation, psychotherapy and other related journals, published mainly after 2015. The study design included randomized controlled trial, pre- and post-test design, and quasi-experimental design. Subjects were ADHD children aged four to 16 years. The physical activities included sport games, sport activities, school physical education courses and rehabilitation training. The measurement methods mainly included cognitive task, scale, questionnaire and electroencephalogram, etc. Physical activity intervention can improve ADHD children's inhibitory control, working memory and cognitive flexibility, as well as improve their motor function, and activity and participation. Conclusion Physical activity intervention can improve the cognitive neural ability, motor ability and emotion-social ability of ADHD children. However, the dose-effect relationship, influencing factors and neural mechanism need further research.

Objective:To investigate the therapeutic mechanism of Wuhutang on respiratory syncytial virus （RSV）-induced asthma in mice and its influence on the expression of signal transducer and activator of transcription 3 （STAT3） in lung tissue. Method:One hundred female BALB/c mice of SPF grade were randomly divided into a normal group and an experimental group. After successful modeling via aerosol inhalation of RSV and ovalbumin （OAV）， the mice in the experimental group were further randomized into the following seven groups： model， positive control （dexamethasone， 1.82 mg·kg<sup>-1</sup>）， STAT3 inhibitor （STATTIC， 3.75 mg·kg<sup>-1</sup>）， STAT3 inducer （colivelin， 1.0 mg·kg<sup>-1</sup>）， and low-， medium-， and high-dose （1.6， 3.2， and 6.4 g·kg<sup>-1</sup>， respectively） Wuhutang groups. The corresponding drugs were administered for two weeks， followed by the detection of airway reactivity using a small animal ventilator， the pathological changes in lung tissue， mucus secretion by goblet cells and collagen deposition in airway were observed by hematoxylin-eosin （HE）， periodic acid-Schiff （PAS） and Masson staining， the serum levels of interleukin-6 （IL-6）， IL-10， and IL-17 were detected by enzyme-linked immunosorbent assay （ELISA）. The mRNA expression levels of TGF-<italic>β</italic><sub>1</sub> and <italic>α</italic>-SMA in lung tissue were detected by fluorescence-based real-time polymerase chain reaction （Real-time PCR）， autophagosomes present in lung tissue were examined by transmission electron microscopy， the protein expression levels of ATG5 and SQSTM1 in dendritic cells （DCs） and STAT3 and p-STAT3 in lung tissue were detected by Western blot. Result:The airway reactivity of the model group was enhanced in contrast to that in the model group （<italic>P<</italic>0.01）， manifested as inflammatory cell infiltration around the lung tissue， excessive metaplasia of goblet cells， and extensive deposition of airway collagen， the expression levels of serum IL-6 and IL-17 were increased （<italic>P<</italic>0.01）， while that of IL-10 declined （<italic>P<</italic>0.01）， the mRNA expression levels of TGF-<italic>β</italic><sub>1</sub> and <italic>α</italic>-SMA were elevated （<italic>P</italic><0.01）， the number of autophagosomes in the lung tissue increased. The protein expression levels of ATG5， STAT3， and p-STAT were up-regulated， while that of SQSTM1 was down-regulated （<italic>P<</italic>0.01）. Compared with the model group， Wuhutang and STATTIC significantly reduced the airway hyperresponsiveness of asthmatic mice （<italic>P<</italic>0.05， <italic>P<</italic>0.01）， alleviated RSV-induced pathological changes in lung tissue， reduced the contents of serum IL-6 and IL-17 （<italic>P<</italic>0.01）， increased serum IL-10 and ATG5 in DCs （<italic>P<</italic>0.01）， down-regulated the mRNA expression levels of TGF-<italic>β</italic><sub>1</sub> and <italic>α</italic>-SMA as well as the protein expression levels of SQSTM1， STAT3 and p-STAT3 （<italic>P<</italic>0.05，<italic>P<</italic>0.01）， and elevated the number of autophagosomes. Conclusion:Wuhutang relieves airway inflammation， improves airway remodeling and reduces airway hyperresponsiveness in RSV-induced asthmatic mice by inhibiting STAT3 protein and up-regulating DC autophagy in lung tissue.
ABSTRACT
In view of the current controversy in the clinical evaluation of the terms of 'prohibition' 'contraindication'， and 'use with caution'， the present study summarized their evaluation elements to provide references for the classification of 'prohibition' 'contraindication'， and 'use with caution' and clinical rational medication of drugs. Based on the ancient and modern representative traditional Chinese medicine （TCM） literature， such as the records on herbal medicines and prescriptions， medical classics， pharmacopoeia， clinical monographs， and papers， this study proposed the evaluation elements and the underlying ideas of 'prohibition' 'contraindication'， and 'use with caution' around the risks and benefits of medication. The results indicate that the evaluation elements of 'prohibition' 'contraindication'， and 'use with caution' include TCM property，syndrome，symptom， TCM compatibility，dosage，and treatment course. When evaluating 'prohibition' 'contraindication'， and 'use with caution' of TCM under specific conditions of medication，we can determine the properties of prohibited or contraindicated drugs prior to figuring out the differences in 'prohibition' 'contraindication'， and 'use with caution'. It is feasible to evaluate the clinical 'prohibition' 'contraindication'， and 'use with caution' in TCM from Chinese medicine， body， and the clinical medication， which are correlated with each other in the practice implementation.
ABSTRACT
OBJECTIVE：To understand the current status of clinical understanding of “prohibiting”“avoiding”“using caution ” in the application of TCM ，and to provide reference for standardizing the connotation and rational application of “prohibiting” “avoiding”“using caution ”of TCM. METHODS ：Based on the theory of “knowledge-attitude-behavior”，doctor-pharmacist questionnaires and patient questionnaires were designed on the basis of literature research and clinical practice. Through the “Tencent questionnaire ”platform，800 doctor-pharmacist questionnaires were distributed to nearly 300 medical institutions from 32 provinces（cities，autonomous regions ）and 800 patient questionnaires were distributed to public patiants who had used TCM nationwide by anonymous online method. After dimensionality reduction of the questionnaire from three dimensions of cognition ， attention and behavior ，the cognition ，attention and behavior of “prohibiting”“avoiding”“using caution ”in the application of TCM were evaluated by 10 points system. RESULTS ：A total of 703 doctor-pharmacist questionnaires were collected ，including 638 valid questionnaires with recovery rate of 87.9％ and effective rate of 90.8％；Cronbach alpha coefficient was 0.90. A total of 644 patient questionnaires were collected ，including 621 valid questionnaires with recovery rate of 80.5％ and effective rate of 96.4％ . The cognition score of doctors and pharmacists to the terms of “prohibiting”“avoiding”“using caution ”in clinical application of TCM was （7.94±1.21），and that of patients was （5.64±1.54）. The score of doctors and pharmacists ’attention to the above terms was （9.47±1.15）（Spearman Rho correlation coefficient with cognition score was 0.077，P＞0.05），and the score of behavioral ability of patients was （7.01±1.71）（Spearman Rho correlation coefficient with cognition score was －0.021，P＞ 0.05）. The score of behavior ability was （7.43 ± 1.72） （Spearman Rho correlation coefficient with cognition score was 0.233，P＜0.01）. TCM textbooks （89.2％），trainingmeetings （66.5％） and herbal prescriptions （58.2％） were the main ways for doctors and pharmacists to learn the above taboos. Medical staff （74.2％）and internet （52.5％）were the main ways for patients to understand the above taboos. CONCLUSIONS ：Doctors，pharmacists and patients pay more attention to the terms of “prohibiting”“avoiding”“using caution ”in the clinical application of TCM ，but their cognition and executive power were low. Clinical cognition of “prohibiting”“avoiding”“using caution ”in the application of TCM is relatively vague，and the corresponding clinical practice behavior is lacking. It is yet to establish clinical specialist consensus in the field of TCM and publicize it actively to improve the level of clinical rational drug use.
ABSTRACT
Objective To study the distribution and drug resistance of pathogens in patients with lung cancer,and analyze the prevention strategies. Methods A total of 312 cases of lung cancer patients with infection treated in our hospital from January 2017 to January 2021 were selected as the research objects.The lower respiratory tract secretions,urine and feces were collected for pathogen culture and drug sensitivity test;the distribution and drug resistance of pathogens were analyzed,and the corresponding prevention strategies were formulated. Results Of the 312 patients, 165 (52.88%) had respiratory tract infection, 79 (25.32%) had oropharyngeal infection, and 68 (21.80%) had urinary tract infection.The highest proportion was respiratory infection.Among the 312 patients,398 pathogens were detected of which 212 Gram-positive bacterias (53.27%)were found of which Staphylococcus epidermidis(15.58%)and Staphylococcus aureus(13.07%)accounted for a relatively high proportion. Among 175 Gram-negative strains,Klebsiella pneumoniae(15.94%)and E.coli (10.05% ) accounted for a large proportion.The resistance rate of Gram-positive bacteria,such as Staphylococcus epidermidis and Staphylococcus aureus,to amikacin,gentamicin and penicillin,was more than 50%,which was sensitive to vancomycin. Gram negative bacteria such as Klebsiella pneumoniae and E.coli have high resistance to common antibiotics,and the drug resistance rate to cefepime and cefazolin is more than 50%,and sensitive to imipenem/cilastatin and imipenem/cilastatin.Among 11 fungi,4 cases were resistant to fluconazole , 36.36%,3 to itraconazole,27.27%,0 to ketoconazole and voriconazole,0.00%. Conclusion The distribution and drug resistance of pathogenic bacteria in patients with lung cancer infection in our hospital have certain characteristics,in which Gram-positive bacteria are mainly Staphylococcus epidermidis and Staphylococcus aureus,Gram-negative bacteria are mainly Klebsiella pneumoniae and Escherichia coli,and there are also a small number of fungal infections.Therefore,we should strengthen the monitoring of etiology and drug resistance,and strengthen the management of hospital disinfection Drug sensitivity results of patients,rational use of antibiotics,so as to improve the treatment effect and reduce the risk of infection.
ABSTRACT
Objective:To compare the survival rate and adverse reactions of patients with advanced hypopharyngeal squamous cell carcinoma undergoing surgery combined with chemoradiotherapy, and to analyze the prognostic factors of patients.Methods:The clinicopathologic data of 78 patients with advanced hypopharyngeal squamous cell carcinoma admitted to the Department of Radiation Oncology of the First Affiliated Hospital of Bengbu Medical University from August 2013 to December 2018 were retrospectively analyzed. The patients were divided into surgery combined with chemoradiotherapy group ( n=27) and chemoradiotherapy group ( n=51) according to different treatment methods. The median follow-up time was 46 months (20-84 months). The main observation indicators were overall survival (OS), progression-free survival (PFS) and local control rate (LCR). Cox regression model was used to analyze the prognostic factors. Results:Until July 31, 2020, 51 of the 78 patients with advanced hypopharyngeal squamous cell carcinoma died, including 6 cases of local recurrence, 11 cases of distant metastasis, and 34 cases of other causes (15 cases of hemorrhage, 15 cases of cachexia, and 4 cases of other diseases). In the surgery combined with chemoradiotherapy group, 12 patients died, accounting for 44.44%. In the chemoradiotherapy group, 39 patients died, accounting for 76.47%. The 1-, 3- and 5-year OS rates of 78 patients were 57.7%, 36.3% and 27.2% respectively, the 1-, 2- and 3-year PFS rates were 49.5%, 38.7% and 32.6% respectively, and the 1-, 2- and 3-year LCR were 53.4%, 40.0% and 34.2% respectively. The 1-, 3- and 5-year OS rates in the surgery combined with chemoradiotherapy group were 74.1%, 50.1% and 44.6%, and those in the chemoradiotherapy group were 49.0%, 29.3% and 12.8%, with a statistically significant difference ( χ2=5.142, P=0.023). The 1-, 2- and 3-year PFS rates in the surgery combined with chemoradiotherapy group were 62.1%, 54.3% and 44.4%, and those in the chemoradiotherapy group were 43.1%, 30.6% and 26.7%, with no statistically significant difference ( χ2=3.222, P=0.073). The 1-, 2- and 3-year LCR of the surgery combined with chemoradiotherapy group were 69.8%, 54.3% and 44.4%, and those in the chemoradiotherapy group were 45.1%, 32.9% and 29.6%, with no statistically significant difference ( χ2=3.576, P=0.059). The results of univariate analysis showed that tumor T stage ( χ2=7.140, P=0.008), N stage ( χ2=4.493, P=0.034) and treatment method ( χ2=5.142, P=0.023) were all independent influencing factors of the OS of patient with advanced hypopharyngeal squamous cell carcinoma; T stage ( χ2=5.807, P=0.016) and N stage ( χ2=6.587, P=0.010) were both independent influencing factors of PFS. The results of multivariate analysis showed that tumor T stage ( HR=2.121, 95% CI: 1.142-3.938, P=0.017), N stage ( HR=2.088, 95% CI: 1.144-3.811, P=0.016) and treatment method ( HR=0.430, 95% CI: 0.226-0.815, P=0.010) were all independent prognostic factors of the OS of patients with advanced hypopharyngeal squamous cell carcinoma; T stage ( HR=1.884, 95% CI: 1.011-3.510, P=0.046) and N stage ( HR=1.904, 95% CI: 1.058-3.429, P=0.032) were both independent prognostic factors of PFS. During the treatment period, there were statistically significant differences in the incidences of radioactive pharyngitis [7.41% (2/27) vs. 39.22% (20/51), χ2=8.821, P=0.003] and radioactive dermatitis [3.70% (1/27) vs. 29.41% (15/51), χ2=7.156, P=0.007] between the surgery combined with chemoradiotherapy group and the chemoradiotherapy group. However, there were no statistically significant differences in the incidences of radioactive oral mucositis [11.11% (3/27) vs. 17.65% (9/51), χ2=0.186, P=0.666], bone marrow suppression [37.04% (10/27) vs. 50.98% (26/51), χ2=1.381, P=0.240], pharynx infection [11.11% (3/27) vs. 5.88% (3/51), χ2=0.143, P=0.706] and tracheal fistula [7.41% (2/27) vs. 0 (0/51), P=0.117] between the two groups. Conclusion:The 1-, 3- and 5-year OS rates in the surgery combined with chemoradiotherapy group are higher than those in the chemoradiotherapy group, and the incidences of adverse reactions are low. T stage, N stage and treatment method are independent prognostic factors for OS of advanced hypopharyngeal squamous cell carcinoma patients, while T stage and N stage are independent prognostic factors for PFS.
