Objective:To analyze the predictive value of serum transforming growth factor-β1 (TGF-β1) and vascular endothelial growth factor (VEGF) in patients with non-small cell lung cancer (NSCLC) after single-port thoracoscopic radical resection.Methods:A total of 50 patients with NSCLC who underwent single-port thoracoscopic radical resection in Affiliated Hospital of Xuzhou Medical University from May 2018 to May 2020 were selected as the observation objects. Serum TGF-β1, VEGF levels and Karnofsky functional status (KPS) scores before and after surgery were compared, and the total incidence of complications was calculated. All subjects were followed up for 3 years, and serum levels of TGF-β1, VEGF and KPS scores were compared between relapsed group and non-relapsed group, survival group and death group. Pearson correlation analysis was used to explore the correlation between TGF-β1, VEGF and KPS scores. The receiver operator characteristic (ROC) curve was plotted and the area under the curve (AUC) was calculated to evaluate the predictive value of serum TGF-β1 and VEGF alone and combined detection in patients with NSCLC after single-port thoracoscopic radical resection.Results:The serum levels of TGF-β1 and VEGF were (7.16±1.94) μg/L and (42.26±5.04) ng/L in 50 patients with NSCLC one month after single-port thoracoscopic radical resection, which were lower than those before surgery [ (13.62±3.52) μg/L and (136.52±20.66) ng/L, t=11.37, P<0.001; t=31.34, P<0.001]. The KPS score one month after surgery was 66.57±8.11, which was higher than that before surgery (53.62±5.62, t=9.28, P<0.001). Postoperative wound healing was delayed in 1 of the 50 patients, pulmonary infection in 1 patient, and no pulmonary embolism and other complications occurred. The total incidence of complications was 4.00%. The serum levels of TGF-β1 and VEGF in patients in the relapsed group ( n=6) were (12.95±4.26) μg/L and (72.46±6.05) ng/L respectively, which were higher than those in the non-relapsed group ( n=44) [ (6.37±1.25) μg/L and (38.14±5.37) ng/L; t=8.34, P<0.001; t=29.99, P<0.001]. The KPS score in the relapsed group was 52.16±8.16, which was lower than that in the non-relapsed group (67.55±12.67, t=2.88, P=0.006). Serum levels of TGF-β1 and VEGF in the death group ( n=5) were (13.99±6.82) μg/L and (75.95±9.05) ng/L, which were higher than those in the survival group ( n=45) [ (6.41±3.06) μg/L and (38.52±8.37) ng/L; t=4.56, P<0.001; t=21.47, P<0.001]. The KPS score in the death group was 1.25±0.34, which was lower than that in the survival group (65.11±12.94, t=10.93, P<0.001). Pearson correlation analysis showed that serum levels of TGF-β1 ( r=-0.45, P<0.001) and VEGF ( r=-0.48, P<0.001) were negatively correlated with KPS scores. ROC curve analysis showed that when the optimal cut-off value of TGF-β1 was 8.14 μg/L, the AUC for predicting recurrence after single-port thoracoscopic radical resection was 0.516 (95% CI: 0.446-0.676), the sensitivity was 71.85%, and the specificity was 80.69%. When the optimal cut-off value of VEGF was 142 ng/L, the AUC was 0.659 (95% CI: 0.534-0.761), the sensitivity was 76.04%, and the specificity was 82.52%. The AUC of the combined detection was 0.828 (95% CI: 0.786-0.951), the sensitivity was 91.86%, and the specificity was 87.52%. The AUC of combined detection was higher than that of serum TGF-β1 ( Z=2.63, P=0.007), VEGF ( Z=2.32, P=0.013) single detection. Conclusion:The serum levels of TGF-β1 and VEGF are significantly decreased in NSCLC patients after one month of single-port thoracoscopic radical resection, and the combined detection of the two has predictive value for recurrence after single-port thoracoscopic radical resection.

Purpose: Varlitinib is a pan-human epidermal growth factor receptor (HER) inhibitor targeting epidermal growth factor receptor (EGFR), human epidermal growth factor receptor 2 (HER2), and HER4. We present a phase Ib/II study of a combination of varlitinib and weekly paclitaxel as a second-line treatment for patients with EGFR/HER2 co-expressing advanced gastric cancer (AGC). Materials and Methods: Patients whose tumors with EGFR and HER2 overexpression by immunohistochemistry (≥ 1+) were enrolled. Varlitinib and paclitaxel were investigated every 4 weeks. After determining the recommended phase II dose (RP2D) in phase Ib, a phase II study was conducted to evaluate the antitumor activity. Results: RP2D was treated with a combination of varlitinib (300 mg twice daily) and paclitaxel. Among 27 patients treated with RP2D, the median progression-free survival and overall survival (OS) were 3.3 months (95% confidence interval [CI], 1.7 to 4.9) and 7.9 months (95% CI, 5.0 to 10.8), respectively, with a median follow-up of 15.7 months. Among 16 patients with measurable disease, the objective response rate (ORR) and disease control rate were 31% and 88%, respectively. Patients with strong HER2 expression (n=8) had a higher ORR and longer OS, whereas those with strong EGFR expression (n=3) had poorer outcomes. The most common adverse events (AEs) of any grade were neutropenia (52%), diarrhea (27%), aspartate aminotransferase/alanine transaminase elevation (22%), and nausea (19%). No treatment-related deaths or unexpected AEs resulting from treatment cessation were observed in patients with RP2D. Conclusion A combination of varlitinib and paclitaxel displayed manageable toxicity and modest antitumor activity in patients with EGFR/HER2 co-expressing AGC who progressed after first-line chemotherapy.

PURPOSE: We conducted a randomized, multicenter, phase III trial to compare S-1 plus docetaxel (DS) with S-1 plus cisplatin (SP) as adjuvant chemotherapy for stage III gastric cancer patients. MATERIALS AND METHODS: Stage III gastric cancer patients who had received curative gastrectomy with D2 lymphadenectomy were randomized into equal groups to receive adjuvant chemotherapy of eight cycles of DS (S-1 70 mg/m2/day on days 1-14 plus docetaxel 35 mg/m2on days 1 and 8) every 3 weeks or SP (S-1 70 mg/m2/day on days 1-14 plus cisplatin 60 mg/m2on day 1) every 3 weeks. The primary endpoint was 3-year disease-free survival (DFS) rate. RESULTS: Between November 2010 and July 2013, 153 patients (75 patients to DS and 78 patients to SP) were enrolled from 8 institutions in Korea. After the capecitabine plus oxaliplatin was approved based on the CLASSIC study, itwas decided to close the study early. With a median follow-up duration of 56.9 months, the 3-year DFS rate between two groups was not significantly different (49.14% in DS group vs. 52.5% in SP group). The most common grade 3-4 adverse event was neutropenia (42.7% in DS and 38.5% in SP, p=0.351). SP group had more grade 3-4 anemia (1.3% vs. 11.5%, p=0.037), whereas grade 3-4 hand-foot syndrome (4.1% vs. 0%, p=0.025) and mucositis (10.7% vs. 2.6%, p=0.001) were more common in DS group. Fifty-one patients (68%) in DS group and 52 (66.7%) in SP group finished planned treatment. CONCLUSION: Our findings suggest that SP or DS is an effective and tolerable option for patients with curatively resected stage III gastric cancer.

Objective To study the effect and mechanism of Momordica anti-HIV protein of 30 ku (MAP30) on the migration of bladder cancer.Methods The IC50 of human bladder cancer 5637 and T24 cells was calculated by methyl thiazolyl tetrazolium (MTT) method.The migration ability of these two cells was evaluated by scratch migration test and Transwell cell migration test.The expression of migrating proteins such as matrix metalloproteinases (MMPs) and adhesion molecule N-cadherin were compared by Western blot.Results Scratch migration test:there were significant differences in migration rates of 5637 cells at 8 h and 22 h (P ＜ 0.05).There were significant differences in migration rates of T24 cells at 22 h (P ＜ 0.05),but no significant differences in migration rates at 8 h (P ＞ 0.05).The expression of Vimentin,Fibronectin,MMP-2,MMP-9 and N-Cadherin in 5637 cells and T24 cells of human bladder cancer decreased significantly after adding MAP30.The E-Cadherin expression in human bladder cancer 5637 cells were decreased,but no target band was detected in human bladder cancer T24 cells.Conclusions The ribosome-inactivating protein MAP30 can effectively inhibit the migration of human bladder cancer 5637 and T24 cells by inhibiting the EMT pathway and inhibiting the expression of MMPs.

Objective To study the effect of enhancer of rudimentary homolog (ERH) gene on migration and invasion in human bladder cancer T24 and 5637 cells.Methods After knocking out the ERH gene of human bladder cancer T24 and 5637 cells,Wound healing assay,Transwell cell migration assay and Transwell cell invasion assay were used to verify the migration and invasion function.Cell migration related protein was detected by Western blot.Nude mouse tail vein transfer assay was used to study the metastasis ability of bladder cancer cells in vivo.Results (1) The Wound healing assay showed that there were significant differences in the migration cell counts of human bladder cancer 5637 and T24 (P ＜ 0.05).(2) There were significant differences in migration and invasion cell counts of Transwell assay (P ＜0.05).(3) Western blot showed that the expression of E-Cadherin in human bladder cancer 5637 cells and T24 cells was significantly increased (P ＜ 0.05) after knocking out ERH gene,while the expression of Fibronectin,Twist,Vimentin and Snail2 protein were significantly decreased (P ＜ 0.05).(4) Nude mouse tail vein transfer assay showed that lung metastases were significantly reduced in the ERH knockout group compared with the normal ERH group.Conclusions Both in vitro and in vivo experiments suggest that ERH knockout affects the migration and invasion of human bladder cancer T24 and 5637 cells.

Objective To understand the basic information and epidemic characteristics of new cases of cysticercosis in Dali Prefecture, Yunnan Province, so as to provide the evidence for formulating the prevention and control strategy of cysticercosis. Methods The data of inpatients in the Dali Parasitic Disease Prevention and Control Center from 2014 to 2017 were collected and the eligible data of new cases of cysticercosis were analyzed by the epidemiological method. Results There were 1 552 patients with cysticercosis, including 549 new cases of cysticercosis. Among the new cysticercosis patients, most were neurocysticer-cosis cases (484 / 549, 88.16%). The symptoms included epilepsy and headache (51.73%), headache (40.98%), and dizziness (18.76%). The new cysticercosis patients were mainly middle-aged male farmers of Bai nationality, and they were distributed in all counties (cities) of Dali Prefecture, especially in Eryuan County (26.78%), and Dali City (19.49%). The annual incidence rate was 4.423/105 in 2014, 3.837/105 in 2015, 3.765/105 in 2016, and 3.442/105 in 2017, and there was no significance among the different years’incidence ( χ² = 4.595, P > 0.05). Conclusion Dali Prefecture is still an endemic area of cysticercosis. Therefore, the monitoring, prevention and control of the disease should be strengthened.
