AIM: To investigate the impact of meteorological factors in different environments in the eastern and western regions of China on the incidence of lipid-abnormal dry eye.METHODS: This is a multicenter retrospective study. From March 1, 2021 to February 28, 2022, all patients with dry eye were selected from the ophthalmology clinic of Nanjing Hospital of Chinese Medicine Affiliated to Nanjing University of Chinese Medicine and Friendship Hospital of Xinjiang Yili Kazakh Autonomous Prefecture. General data(gender, age, employment and education)and climate data for outdoor environments(temperature, humidity, air quality index and wind)on the day of the visit were collected. Patients who met the inclusion and exclusion criteria were selected. Single factor, multiple factors and nonlinear model analysis were applied to identify environmental factors of lipid-abnormal dry eye in both regions.RESULTS: There was no significant difference in the incidence of lipid-abnormal dry eye between Nanjing and Yili in different seasons. The incidence of lipid-abnormal dry eye in Yili was significantly higher in all seasons than in Nanjing(P<0.001). The results of univariate research showed that the factors affecting the incidence of lipid-abnormal dry eye were gender, employment, humidity, air quality, and wind. The results of multivariate Logistic regression analysis showed that humidity, temperature and air quality were statistically significant, and remained significant after adjusting for the three confounding factors of age, gender and employment situation. Nonlinear analysis showed that the probability of lipid-abnormal dry eye increased with the decrease of temperature when the temperature was below 10℃; within the range of 10℃～15℃, the probability of lipid-abnormal dry eye tended to stabilize. When the temperature exceeded 15℃, the probability of lipid-abnormal dry eye increased with the increase of temperature. Humidity was negatively correlated with the onset of lipid-abnormal dry eye. As humidity increased, the probability of lipid-abnormal dry eye decreased.CONCLUSIONS: The risk of lipid-abnormal dry eye in Yili is higher than that in Nanjing throughout the four seasons. Humidity, temperature, air quality and other environmental and meteorological factors can all affect the incidence of lipid-abnormal dry eye.

Objective To establish a novel defined pyroptosis-related genes risk model of kidney renal clear cell carcinoma. Methods Data of 522 patients with KIRC and 72 normal tissue samples were respectively downloaded from the Cancer Genome Atlas ( TCGA) database and Genotype-Tissue Expression ( GTEx) database. Differential analysis was performed between data of TCGA and GTEx. Univariate Cox regression analysis, multivariate Cox regression analyses and LASSO Cox regression analysis were used to establish a prognostic risk model. Data from the International Cancer Genome Consortium (ICGC) database was used as an external validation cohort. Gene ontology ( GO) enrichment analysis and Kyoto Encylopedia of Genes and Genomes (KEGG) pathway analysis were used to explore the differences of gene functions and pathways between high-risk and low-risk groups. The CIBERSORT database was used to explore the immune infiltration of high-risk and low-risk groups. Results Through differential analysis, we obtained 13 differentially expressed pyroptosis-related genes. Univariate Cox regression analysis, multivariable Cox regression analyses and LASSO Cox regression analysis were used to establish a 6-gene risk model. Kaplan-Meier analysis indicated that survival time in high-risk group was shorter than low-risk group in both cohorts. The area under the curve ( AUC) was 0. 710 for 1-year, 0. 683 for 2-year, and 0. 727 for 3-year survival in the TCGA_KIRC cohort. The AUC was 0. 592 for 1-year, 0. 531 for 2-year, and 0. 545 for 3-year survival in the ICGC_RECA cohort. Independent prognostic analysis indicated that risk score was an independent prognostic factor. GO enrichment analysis and KEGG pathway analysis showed that it was mainly associated with immune and inflammatory responses. The result of tumor immune infiltration showed that the high-risk group had low infiltration levels of regulatory T cells , natural killer cells, monocytes, M2 macrophages and eosinophils and high infiltration level of B cells, CD8+T cells and follicular helper T cells. Conclusion Pyrolysis-related genes may play an important role in KIRC tumor immunity, and the 6-gene risk model can provide a forecast basis for personalized treatment of patients with KIRC.

Objective To explore the efficacy of imatinib and dasatinib for treatment of newly diagnosed chronic my-elogenous leukemia chronic phase(CML-CP)patients. Methods Forty patients with CML-CP were selected in the Luoyang Central Hospital Affiliated to Zhengzhou University from January 2010 to June 2016. The patients were divided into imatinib group(n = 22)and dasatinib group(n = 18)according to the treatment method. The patients in imatinib group received ima-tinib orally for 1 year;the patients in dasatinib group received dasatinib orally for 1 year. The treatment response and curative effect of patients in the two groups were evaluated at 3,6 months after treatment;the aderverse reactions of patients in the two groups were evaluated at 12 months after treatment. Results The rate of optimal cytogenetic response of patients in imatinib group and dasatinib group was 45. 5％(10 / 22),55. 6％(10 / 18)at 3 months after treatment and 36. 4％(8 / 22),38. 9％(7 /18)at 6 months after treatment;the rate of optimal molecular response of patients in imatinib group and dasatinib group was 50. 0％(11 / 22),55. 6％(10 / 18)at 3 months after treatment and 31. 8％(7 / 22),38. 9％(7 / 18)at 6 months after treatment;the rate of failture to achieve a complete cytogenetic responses(CCyR)of patients in imatinib group and dasatinib group was 18. 2％(4 / 22),5. 6％(1 / 18)at 12 months after treatment;the rate of failure to achieve BCR-ABLIS≤1％ of patients in ima-tinib group and dasatinib group was 18. 2％(4 / 22),5. 6％(1 / 18)at 12 months after treatment. The rate of optimal cytogenetic response and optimal molecular response of patients in dasatinib group at 3,6 months after treatment were significantly higher than those in the imatinib group(P < 0. 05);the rate of failure to achieve a CCyR and BCR-ABLIS≤1％ of patients in dasat-inib group at 12 months after treatment were significantly lower than those in the imatinib group(P < 0. 05). The mutation rate of BCR-ABL kinase domain of patients in imatinib group and dasatinib group was 13. 6％(3 / 22)and 5. 6％(1 / 18)respective-ly;the mutation rate of BCR-ABL kinase domain of patients in imatinib group was significantly higher than that in the dasatinib group(P < 0. 05). Conclusion Compared with imatinib,dasatinib has better efficacy in treatment of CML-CP patients,and with lower mutation rate of BCR-ABL kinase domain. So,dasatinib is suitable for clinical use.
