Objective To observe the effect for the patients with esophageal carcinoma surgery by guben decotion combined with radiotherapy. Methods 64 cases of patients with esophageal carcinoma after surgery were randomly divided into two groups, patients in control group(n = 30) were treated by radiotherapy only. Patients in treatment group(n = 34) were treated by guben decotion combined radiotherapy. Investigated the digestive tract response,the marrow suppression,the radioactive response and the lifetime,the Kamofsky grading after the radiotherapy,contrasted two group of tumor patient's poisonous side reaction and the curative effect. Results B group of Karnofsky grading is higher than A group obviously;B group of lifetimes surpass A group obviously;B group of poisonous side reactions are lower than A group obviously. Conclusion The lifequality and lifetime of the patients with esophageal carcinoma after surgery treated by guben decotion combined with radiotherapy were improved obviously,and the poisonous side reaction of the radiotherapy were reduced obviously.

Objective:To analyze the clinical efficacy of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) in patients with advanced NSCLC.Methods:We collected 23 cases of NSCLC advanced patients, who were treated in the affiliated Cancer Hospital of Guangzhou Medical University from January 2015 to March 2020. And these 23 cases of patients with first-generation EGFR-TKIs resistance were treated with the third-generation EGFR-TKI drugs. We analyzed their clinicopathological characteristics, studied their therapeutic effects, and followed up their progression-free survival (PFS).Results:It is showed that 16 of 23 cases (69.56%) were got local progression and 7 of 23 cases (31.43%) were found with systemic progression. Briefly, the median PFS of the 23 patients was 17.5 months. A total of 7 cases occurred rashes after taking EGFR-TKI, and 3 cases got abnormal liver function. Fortunately, they were all improved after symptomatic treatments. Additionally, no bone marrow suppression (granulocytes, neutropenia, thrombocytopenia, anemia) and digestive tract reactions (nausea, vomiting, diarrhea) were occurred in 23 cases of NSCLC patients. The mental and physical improvement of EGFR-TKI in the third generation of 19 patients was more obvious than that in the first generation of EGFR-TKI. Among them, 15 cases showed more obvious lesion shrinkage after third-generation EGFR-TKI treatment. 4 patients with GGO had cleaner disappearance than that of the first-generation EGFR-TKI.Conclusions:Compared with traditional chemotherapy, the first-generation EGFR-TKI resistance treatment with three-generation EGFR-TKI treatment has better efficacy with reduced toxic and side effects, and significantly improved the life quality of advanced NSCLC patients.

Objective:To explore the effect of transcatheter chemoembolization (TACE) on recurrence and survival time of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) following curative resection.Methods:Of 724 HBV-related HCC patients who underwent curative resection in the Third Affiliated Hospital of Naval Military Medical University from October 2009 to August 2010 were retrospectively analyzed. Patients who underwent resection only and no recurrence within 3 months after surgery were classified into control group, while those received adjuvant TACE were classified into intervention group. The patients were further divided into 4 sub-groups according to tumor size, tumor number and tumor thrombus which were defined as risk factors for recurrence. Tumor diameter ≤5 cm with low or high risk factors (tumor number ≥2 or presence tumor thrombus) were in group 1 and group 2 respectively, tumor diameter >5 cm with low or high risk factors for recurrence were in group 3 and group 4 respectively.Results:A total of 354 patients were classified in the control group and 370 patients were classified in the TACE group. Adjuvant TACE showed an overall survival benefit in patients with tumor diameter >5 cm and presenting high risk factors, the 1-, 3-, and 5-year cumulative survival rates were 90.1%, 67.6%, and 46.5%, respectively, for the lip-TACE group 83.3%, 52.4%, and 33.3%, respectively, for the control group ( P<0.05). Patients with the tumor diameter ≤5 cm, there was no significant difference in cumulative survival between the TACE group and the control group regardless of the risk level ( P>0.05). There was no significant difference in recurrence curve between TACE group and control group in each stratum. Conclusions:Adjuvant TACE had no preventive effect on recurrence, but TACE can prolong the survival time of HCC patients with high risk factors for recurrence.

Objective To discuss the clinical application of getting the images related to the partogram content using the intrapartum ultrasound. Methods One hundred twenty-three pregnant women who tried vaginal delivery in Huai'an Maternity and Children Hospital were included in this study. Intrapartum ultrasound was performed during the progression of labor every two hours. To obtain the images related to the fetal position by transabdominal or transperineal ultrasound in transverse view, determining the fetal head position; to obtain the images related to the fetal head station by transperineal ultrasound in mid-sagittal and transverse views , measuring the angle of progression (AOP) and the fetal head-perineum distance (HPD); to obtain the images related to the cervical dilatation by transperineal ultrasound in transverse view, measuring the anteroposterior diameter of the cervical dilatation. Results This study included 123 pregnant women, 123 images were obtained related to the fetal position; 122 images of AOP related to the fetal head station were measured; and 123 images of HPD related to the fetal head station were measured; 121 images related to the cervical dilatation, all the images can clearly displayed various ultrasonic markers, which can be used to determine the fetal position, the fetal head station and the cervical dilation. Conclusion Intrapartum ultrasound could get the images related to the partogram content, it could be studied to use in labor.

Necrosis is a form of cell death, which is related to various serious diseases such as cardiovascular disease, cancer, and neurodegeneration. Necrosis-avid agents (NAAs) selectively accumulated in the necrotic tissues can be used for imaging and/or therapy of related diseases. The aim of this study was to preliminarily investigate necrosis avidity of I-evans blue (I-EB) and its mechanism. The biodistribution of I-EB at 24 h after intravenous administration showed that the radioactivity ratio of necrotic to viable tissue was 3.41 in the liver and 11.82 in the muscle as determined by counting in model rats. Autoradiography and histological staining displayed preferential uptake of I-EB in necrotic tissues. nuclear extracts from necrotic cells exhibited 82.3% of the uptake in nuclei at 15 min, as well as 79.2% of the uptake at 2 h after I-EB incubation. The DNA binding study demonstrated that evans blue (EB) has strong binding affinity with calf-thymus DNA (CT-DNA) (=5.08×10 L/(mol/L)). Furthermore, the accumulation of I-EB in necrotic muscle was efficiently blocked by an excess amount of unlabeled EB. In conclusion, I-EB can not only detect necrosis by binding the DNA released from necrotic cells, but also image necrotic tissues generated from the disease clinically.
