Objective:A method that is based on microfluidic cell chip technology was developed for the first time to analyze CD14+monocyte myeloperoxidase (MPO) expression in myelomonocytic leukemia (M4) patients. CD14+monocyte MPO expression in M4 patients was preliminarily discussed. Methods:a. The chip was prepared by using polydimethylsiloxane as the host material and by secondary foam molding. b. A total of 48 clinically diagnosed M4 patients and 52 patients with normal myelogram were included as the test and control groups, respectively. c. A method based on the microfluidic cell chip approach was established to detect CD14+mono-cytes and to determine the positive rate and degree of MPO expression in the cells. d. The microfluidic cell chip technique was used to compare CD14+monocyte MPO expression in M4 patients with that in the control. Results:a. The designed microfluidic single cell analysis chip allowed the entry of granulocytes into the corresponding microfluidic channels. Thus, blood cells were separated. Numer-ous ghost corpuscles surrounded the separated white blood cells (WBCs). WBC morphology did not show obvious changes. b. The posi-tive rate of MPO expression and the activity of CD14+monocytes in the bone marrow of M4 patients were significantly higher than those in the bone marrow of the control (P<0.05). Conclusion:A method based on microfluidic single cell technology was developed for the first time to analyze the MPO expression in CD14+monocytes. CD14+monocyte MPO activity in M4 patients was significantly higher than in the control. CD14+monocyte MPO activity can be used as an auxiliary examination marker for clinical diagnosis.

Objective:To analyze the invasion characteristics and prognostic factors of patients with Masaoka-Koga stage Ⅲ thymoma.Methods:The tumor invasion characteristics of 179 patients who were diagnosed with Masaoka-Koga stage Ⅲ thymoma and treated in Affiliated Cancer Hospital of Zhengzhou University from January 2000 to June 2018 were analyzed retrospectively. According to the treatment methods, all patients were divided into the radical operation group ( n=94), palliative operation group ( n=39) and simple biopsy group ( n=46). The χ2 test was used to compare the classified variables, Kaplan- Meier method was utilized to calculate the cumulative survival rate, log-rank method was used for group comparison and univariate analysis, and Cox’s regression model was used for multivariate analysis. Results:Mediastinal pleural invasion (86.0%) was the most common site, followed by pericardium (50.8%), great vessel (40.8%) and lung (36.3%). The proportion of macrovascular invasion in the radical operation group was 14.9%, significantly lower than 79.5% and 60.9% in the palliative surgery group and biopsy group (both P<0.001). Multivariate analysis showed that the nature of operation ( P<0.001), age ( P=0.011), radiotherapy ( P=0.020) were the independent factors affecting overall survival (OS), while nature of operation ( P<0.001), age ( P=0.004), radiotherapy ( P=0.020), number of invasive organs ( P=0.023) and pathological type ( P=0.016) were the independent factors affecting progress-free survival (PFS). Conclusions:For patients with Masaoka-Koga stage Ⅲ thymoma, mediastinal pleura is the most common site of invasion, pericardium, lung and great vessels are also commonly invaded. The invasion of mediastinal pleura, pericardium and lung exerts slight effect on surgical resectability, whereas great vessel involvement can significantly affect surgical resectability. OS and PFS in patients undergoing radical resection are significantly better than those in patients treated with palliative resection and biopsy. Radical resection is the most important factor affecting prognosis.

Objective:To observe the clinical efficacy of Yin-Yang balancing acupuncture plus Tuina(Chinese therapeutic massage)for post-stroke depression(PSD). Methods:A total of 72 PSD patients were randomized into an acupuncture-Tuina group and a Western medicine group using the random number table method,with 36 cases in each group.The Western medicine group was treated with fluoxetine hydrochloride capsules.The acupuncture-Tuina group was treated with Yin-Yang balancing acupuncture plus Tuina therapy.Both groups were treated for 4 weeks.After treatment,the clinical efficacy was compared,and the changes in Hamilton depression scale(HAMD)score,National Institute of Health stroke scale(NIHSS)score,serum neurotransmitter levels,and electroencephalogram(EEG)were observed. Results:The total effective rate of the Western medicine group and the acupuncture-Tuina group was 83.3%and 94.4%,respectively.There was a significant difference in the total effective rate between the two groups(P<0.05).After treatment,the serum levels of 5-hydroxytryptamine(5-HT),norepinephrine(NE),and dopamine(DA)were higher than those in the same group before treatment,and the intra-group differences were all statistically significant(P<0.05).The serum levels of 5-HT,NE,and DA in the acupuncture-Tuina group were higher than those in the Western medicine group,and the differences between the groups were statistically significant(P<0.05).After treatment,the scores of HAMD and NIHSS in both groups decreased,and the intra-group differences were statistically significant(P<0.05).The scores in the acupuncture-Tuina group were lower than those in the Western medicine group,and the differences between the two groups were all statistically significant(P<0.05).After treatment,the EEG diffuse wave[(delta+theta)/(alpha+beta)]ratio(DTABR)and delta/beta ratio(DBR)in both groups decreased,and the intra-group differences were statistically significant(P<0.05).The ratios in the acupuncture-Tuina group were lower than those in the Western medicine group,and the differences between the two groups were statistically significant(P<0.05). Conclusion:Yin-Yang balancing acupuncture plus Tuina therapy has a better efficacy than oral fluoxetine hydrochloride capsules in the treatment of PSD,which can increase the levels of serum 5-HT,DA,and NE,and regulate brain waves.

Objective:To evaluate the efficacy and safety of stereotactic ablative radiotherapy (SABR) in patients with pulmonary oligometastases.Methods:Clinical data of patients with pulmonary metastases treated with SABR from 2011 to 2018 were retrospectively analyzed. The local control rate (LCR) and overall survival (OS) were calculated by Kaplan- Meier method. log-rank test was used for univariate analysis and Cox’s regression model for multivariate analysis. Results:A total of 214 lung metastases were detected in 159 patients, and the median follow-up time was 43 months. The 1-, 3-and 5-year LCR were 90.1%, 73.9% and 65.8%, respectively. The 1-, 3-and 5-year OS were 73.8%, 43.6% and 11.9%, respectively. Univariate analysis showed that biological effective dose (BED)&ge;100 Gy was significantly correlated with LCR ( P=0.033). Cox’s multivariate analysis showed that BED and primary tumor source were the independent prognostic factors of LCR ( P=0.023, P=0.043). No>grade 3 adverse events were observed in all patients during treatment. Conclusions:SABR is a safe and effective treatment of lung oligometastases. SABR should be actively aD ministered for pulmonary oligometastases, especially for those with lesions from lung cancer and the radiation dose should be selected as BED &ge;100 Gy.

Objective To evaluate the prognostic value of a novel prediction model based on fibrinogen concentration in combination with neutrophil-to-lymphocyte ratio (F-NLR score) in patients with esophageal squamous cell carcinoma (ESCC) receiving neoadjuvant therapy and investigate their relationship with pathologic complete response (pCR).Methods Clinical data of 218 eligible ESCC patients treated with neoadjuvant therapy in the Affiliated Cancer Hospital of Zhengzhou University between 2012 and 2015 were retrospectively analyzed.The cut-off values for fibrinogen and neutrophil-to-lymphocyte ratio (NLR)were defined by the receiver operating characteristic (ROC) curve.The effects of different F-NLR scores on survival and pCR were evaluated.The survival rate was analyzed using the Kaplan-Meier method.The relationship among fibrinogen,NLR and pCR was analyzed by using Wilcoxon rank sum test.Results The 3-year overall survival (OS) rates with F-NLR scores of 0,1 and 2 were 72.1％,66.5％ and 50.2％(P=0.010),respectively.The corresponding 3-year disease-free survival (DFS) rates were 64.1％,60.2％ and 45.4％ (P=0.012),respectively.The clinical prognosis of patients with an F-NLR score of 2 was significantly worse compared with those of their counterparts with an F-NLR score of 0-1 (P=0.003).Multivariate analysis demonstrated that the F-NLR score (P=0.004) and TNM stage (P=0.000) were the independent prognostic factors.Conclusions The F-NLR score can be used as an independent prognostic factor for ESCC patients treated with neoadjuvant therapy,which is promising supplement to current TNM staging system,thereby facilitating more accurate risk stratification analysis and achieving individualized multidisciplinary treatment for ESCC patients.

Objective To explore the role of radiotherapy in the treatment of primary central nervous system lymphoma. Methods Clinical data of 60 patients diagnosed with primary central nervous system lymphoma from September 2010 to December 2017 were retrospectively analyzed. Among them, 50 cases were diagnosed by histopathological examination after stereotactic biopsy or tumor resection and 10 patients were diagnosed by gadolinium enhanced magnetic resonance imaging ( MRI) . Fifty-two patients underwent chemotherapy, and 45 of them received methotrexate-based chemotherapy, 25 received rituximab-based regimen. Twenty-seven patients were given with planned whole brain radiotherapy, while 33 patients were not. Salvage radiotherapy was delivered in 9 patients after treatment failure. Results The median follow-up time was 28 months ( 5-70 months) . The median overall survival time and median progression-free survival time of the whole patients was 22 months ( 5-65 months) and 13 months ( 5-55 months) , respectively. The 4-year overall survival rate and progression-free survival rate were 61% and 33%, respectively. The 4-year overall survival rates between patients with and without planned whole brain radiotherapy were 68% and 54% ( P=0.083) . The 4-year progression-free survival rates between patients with and without planned whole brain radiotherapy were 47% and 20% ( P=0.014) , respectively. Patients with and without salvage whole brain radiotherapy had a 4-year overall survival of 49% and 68%, respectively ( P=0.398) . Among patients who received whole brain radiotherapy, patients with a lower dose of ≤36 Gy had a similar overall survival compared with those with a higher dose of>36 Gy ( 80% vs. 45%, P=0.136) . Conclusions Radiotherapy is part of the comprehensive treatment of primary central nervous system lymphoma. Planned radiotherapy may bring clinical benefits to patients during the comprehensive therapy. However, the irradiation dose to the whole brain should not be too high because of neurotoxicity.

Objective: To evaluate the clinical efficacy and prognostic factors of recurrent esophageal squamous cell carcinoma after neoadjuvant therapy combined with surgery. Methods: From December 2011 to December 2015, 152 cases of recurrent thoracic esophageal squamous cell carcinoma after neoadjuvant therapy combined with surgery were retrospectively analyzed. The overall survival (OS) after treatment failure, clinical efficacy and prognostic factors of different salvage treatments were analyzed. OS was calculated by Kaplan-Meier method. Prognostic analysis was performed by using multivariate Cox regression model. Results: The median interval of the first recurrence was 10.6(2.0 to 69.1) months. The median OS after recurrence was 8.0(0.8 to 43.3) months. The 1-, 2-and 3-year OS rates after recurrence were 36.0%, 15.1% and 5.2%, respectively. The median OS of patients with locoregional recurrence alone, distant metastasis alone and locoregional recurrence combined with distant metastasis was 11.3(1.8 to 43.3) months, 6.7(1.2 to 28.6) months and 5.1(0.8 to 22.9) months, respectively. Multivariate analysis demonstrated that neoadjuvant chemotherapy (P=0.009), ypTNM stage (P=0.012), comprehensive treatment after recurrence (P=0.000) and locoregional recurrence (P=0.026) were independently correlated with the OS of patients with recurrent esophageal squamous cell carcinoma. Conclusions Neoadjuvant therapy, ypTNM stage, recurrence pattern and post-recurrence treatment are the independent risk factors for clinical prognosis of patients with recurrent esophageal squamous cell carcinoma after neoadjuvant therapy combined with surgery. Clinical prognosis of patients with recurrent esophageal squamous cell carcinoma after neoadjuvant therapy is not satisfactory. After recurrence, combined treatment mode should be adopted according to the site of recurrence and neoadjuvant treatment mode to maximize the benefits of salvage treatment.

Objective: To compare the effect of neoadjuvant chemoradiotherapy (NCRT) and neoadjuvant chemotherapy (NCT) on the survival of patients with esophageal cancer. Methods: Clinical data of 275 cases of thoracic esophageal squamous cell carcinoma treated with neoadjuvant therapy combined with surgery from December 2011 to December 2015 were analyzed retrospectively. The data of treatment and follow-up were complete and analyzable. There were 70 cases in the NCRT group and 205 cases in the NCT group. The survival rate was calculated by Kaplan-Meier method and statistically compared by log-rank test, and multivariate analysis was performed by Cox regression model. Results: The median follow-up time was 32(3-84) months. The median survival time and recurrence-free survival time was 42(3-84) months and 30(3-84) months, respectively. The overall 3-and 5-year survival rates were 56.8% and 45.9%, respectively, and the 3-and 5-year recurrence-free survival rates were 45.1% and 38.9%, respectively. The median survival time in the NCRT and NCT groups was 46(7-84) and 40(4-74) months, and the median recurrence-free survival time was 31(3-84) and 28(3-69) months, respectively. The 3-and 5-year overall survival of the two groups were 59.1%, 47.1% and 56.3%, 47.5%(P=0.515), and the 3-and 5-year recurrence-free survival were 44.5%, 40.1% and 47%, 39%, respectively. There was no significant difference in the survival between two neoadjuvant therapy modes (P=0.554). Multivariate analysis showed that postoperative pathological TNM staging was an independent factor affecting the prognosis of patients with esophageal cancer (P=0.001). Conclusions The survival results of NCRT are similar to those of NCT. Postoperative pathological staging is an independent survival factor.

Disulfiram (DSF) has been widely used in clinical treatment of alcoholism.To date,in vivo and in vitro experiments have demonstrated that DSF has strong anti-cancer activity and could improve patient's survival,and the underlying mechanism has been elaborated.In addition,it was reported that,during radiotherapy,DSF could protect normal tissue and cells meanwhile enhance the radiosensitivity of tumor cells by forming complexes with copper ions,suppressing cancer stem cells and inhibiting ubiquitin-proteasome system activity in cancer cells.This review summarizes the completed and ongoing clinical trials of disulfiram,and its anti-tumor mechanisms and advances in radiation biology.
