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 investigate the expression and clinical significance of long non-coding RNA (lncRNA) H19 and lncRNA maternally expressed gene 3 (MEG3) in the serum of patients with gastric cancer (GC).Methods:A total of 87 GC patients admitted to the First People′s Hospital of Suqian (July 2017 to August 2018) were selected as the GC group, 51 patients with benign tumors as the benign tumor group, and 40 healthy people with physical examination as the healthy control group. The expression levels of lncRNA H19 and lncRNA MEG3 in serum were measured; the relationship between the expression levels of the two and clinicopathological features and prognosis of patients with GC was analyzed.Results:The levels of serum lncRNA H19 in healthy control group, benign tumor group and GC group were gradually increased, and lncRNA MEG3 level was gradually decreased ( P<0.05); the serum lncRNA H19 level in GC group was related to tumor invasion depth, tumor node metastasis (TNM) stage and lymph node metastasis. The level of lncRNA MEG3 was related to the degree of differentiation, TNM stage and lymph node metastasis ( P<0.05). Among the 87 GC patients , 63 patients were followed up for 13-32 months with an average of (23.54±4.18)months. Kaplan Meier survival curve showed that the overall survival rate of high serum lncRNA H19 group and low serum lncRNA MEG3 level group was significantly lower than that of low serum lncRNA H19 level group and high serum lncRNA H19 level group. Multivariate Cox regression analysis showed that lncRNA H19 ( HR=3.442, 95% CI=0.089-23.421) was an independent prognostic factor for GC patients, and lncRNA MEG3 ( HR=4.386, 95% CI=0.934-20.596) was a protective factor ( P<0.05); receiver operating characteristic (ROC) curve showed that the sensitivity, specificity and accuracy of serum lncRNA H19+ lncRNA MEG3 [area under curve (AUC)=0.922, 95% CI=0.861-0.962] were higher than those of serum lncRNA H19 (AUC=0.840, 95% CI=0.771-0.904) and lncRNA MEG3 (AUC=0.830, 95% CI=0.753-0.890). Conclusions:The level of serum lncRNA H19 in GC patients is significantly increased, and the level of lncRNA MEG3 is significantly reduced, which is closely related to tumor occurrence, development and prognosis. Combined detection of the two can enhance the diagnostic value of GC.

ABSTRACT

Objective: To construct and identify the monoclonal antibody of ATP synthase beta subunit (ATP5B) with high purity, and to lay foundation for further study. Methods: The ATP5B gene was amplified by PCR and cloned into the pET28a vector and transformed into K. coli BL21 (DE3). The protein expression was induced by IPTG and then the fusion protein was purified by nickel affinity chromatography column. The protein purity was detected by SDS-polyacrylamide gel electrophoresis (SDS-PAGE). Three female Balb/C mice were immunized with purified fusion protein and the tail vein blood was taken to detect the titer of ATP5B antibody by indirect enzyme-linked immunosorbent assay (ELISA). The spleen cells from the immunized mice with the highest serum titer were mixed with the SP2/0 cells to establish the hybridoma cells and the fused cells were screened by indirect ELISA and monoclonally cultured. Karyotype analysis were performed in the positive cells. The hybridoma cells were intraperitoneally injected into 12 weeks old BALB/C mice to estabilish the ascites models. The titer of ascites was detected by indirect ELISA. The purity of tlie antibody was detected by SDS-PAGE. The antibody subtype was detected by ELISA. Results: After PCR amplification, a specific band of 1 455 bp was obtained, and the pET28a empty vector was ligated to obtain a recombinant pET28a/ATP5B vector. The target protein was expressed in the IPTG-induced bacteria solution; the SDS-PAGE results showed that the protein band was found at 51 000. The indirect ELISA results showed that the serum titer of the venous blood of immunized mice was up to 1: 64 000. In karyotype analysis, the total number of chromosomes in hybridoma cells was about the sum of myeloma cells and normal mouse spleen cells. The mouse ascites was prepared with the hybridoma cell line, and the highest titer of tlie antibody was 1 5 240 000. The subtype of the monoclonal antibody produced by the hybridoma cells was IgGl. Conclusion: The monoclonal antibody against ATP5B protein is successfully prepared by cloning, expressing and purifying the recombinant protein.

ABSTRACT

The author introduced the moral health′s connotation , analyzed the significance of moral health to mental health:that moral health to mental health has previously neglected the profound influence , moral health not only help achieve positive emotions , which helps to improve well -being , is more advantageous to the healthy de-velopment of psychological health .Similarly, mental health and to a certain extent , affects the formation of moral health survey found that in the causes of the formation of adolescent moral problems , psychological problems earlier is neglected factors , put forward only to mental health as the basis of moral cultivation , is the only right path for a-chieving the moral health .
