RAN Deyuan, YU Yunliang
DOI: 10.19739/j.cnki.issn1001-9510.2021.03.001
Objective
To analyze the expression of PRKCI in pancreatic cancer, to clarify its role in the prognosis of pancreatic cancer, and to analyze the relationship between PRKCI and immune cell infiltration in tumor microenvironment.
Methods
Oncomine, GEPIA, HPA and CCLE databases were used to analyze the expression of PRKCI in pancreatic cancer tissues and cell lines; GEPIA was used to analyze the relationship between PRKCI expression and the prognosis of pancreatic cancer patients; String database was used to analyze the protein interacting with PRKCI; TIMER was used to detect the correlation between PRKCI expression and tumor purity and immune cell infiltration.
Results
The expression of PRKCI in pancreatic cancer tissues was significantly higher than that in normal pancreatic tissues. PRKCI was also highly expressed in pancreatic cancer cell lines. The overall survival and disease-free survival of pancreatic cancer patients with high PRKCI expression were significantly lower than those with low PRKCI expression (
P
<0.01) and the expression of PRKCI was significantly correlated with the stage of pancreatic cancer. Proteins interacting with PRKCI include CDC42, NUMB, SQSTM1 and so on, which are mainly involved in inflammatory reaction and protein phosphorylation. The expression of PRKCI was negatively correlated with CD4
+
T cells, PD-L1 and CTLA-4 in pancreatic cancer.
Conclusion
PRKCI is highly expressed in pancreatic cancer. The expression of PRKCI is significantly correlated with the prognosis and immune cells. PRKCI may act as a potential therapeutic target for pancreatic cancer.

LAO Kaixue, DIAO Xinghua, LI Qingqing, QIU Yuchen, MEI Juanjuan, WANG Yanlin
DOI: 10.19739/j.cnki.issn1001-9510.2021.03.003
Objective
To study the effects of endometrial thickness, patterns and blood flow types on the clinical outcome of frozen embryo transplantation in patients of different ages.
Methods
The clinical data of patients who received frozen embryo transplantation were retrospectively analyzed and 853 cycles were included. The patients were divided into different age groups. The endometrium thickness, patterns and blood flow types were evaluated by vaginal color Doppler ultrasound. The influence of endometrium thickness, patterns and blood flow types on pregnancy outcome in patients of different ages was studied. The predictive value of endometrial thickness, patterns and blood flow types on clinical pregnancy outcome was analyzed by using ROC curve.
Results
With the increase of age, the embryo implantation rate and pregnancy rate of patients showed a downward trend. The pregnancy rate is the highest when the endometrial thickness is 8-14mm, followed by ＜8 mm, and the pregnancy rate ≥14 mm is the lowest, but the trends are different for patients of different ages. There was no pregnancy in the type C group of patients of all ages, and the pregnancy rate and implantation rate of the endometrium in the type A group were not different from those in the type B group. With the increase in the abundance of endometrial blood flow, the pregnancy rate of patients gradually increased. The implantation rate of type II group was the highest, followed by type III group, and the implantation rate of type I group was the lowest. However, there was no statistical difference in pregnancy rate and implantation rate among the three groups of data in each age group. The ROC curve suggests that the endometrial blood flow types can be used as indicators to predict clinical pregnancy outcome.
Conclusion
The clinical pregnancy rate and implantation rate of embryo transfer during freeze-thaw cycles decrease with age. Endometrial thickness, patterns and blood flow types can affect the implantation rate and clinical pregnancy rate of embryo transfer. Endometrial blood flow types on the day of endometrial transformation can predict the clinical pregnancy outcome of embryo transfer patients during the freeze-thaw cycle.

DOI: 10.19739/j.cnki.issn1001-9510.2021.03.007
Objective
To investigate the level of IL-17 and IL-23 in peripheral blood of patients with rectal cancer to analyze their association with clinicopathological characteristics and prognosis before and after radiotherapy.
Methods
Blood samples were collected from 24 patients with rectal cancer before and after radiotherapy, and the levels of IL-17 and IL-23 in peripheral blood of the patients were detected by ELISA. All patients received 50Gy radiotherapy after surgery.
Results
Protein expression level of IL-17 was correlated with tumor differentiation and lymph node metastasis in rectal cancer patients (
P
<0.05), whereas serum IL-23 level showed correlated only with lymph node metastasis (
P
<0.05). Significant differences were observed between serum IL-17 and IL-23 levels in rectal cancer patients before and after radiotherapy (
P
<0.05). Serum levels of IL-17 and IL-23 can be used to effectively diagnose tumor differentiation and lymph node metastasis of rectal cancer patients. Multivariate Cox proportional hazards regression analysis showed that the expression of IL-23 may be independent risk factor for poor prognosis (
P
<0.05).
Conclusion
The concentration of IL-17 and IL-23 obviously increased in peripheral blood of patients with rectal cancer, both of them were correlated with radiotherapy. Detection of IL-17 and IL-23 levels has certain clinical significance in the diagnosis and prognosis of rectal cancer patients.
