Objective:To explore the prognostic value of lymphocyte subsets in adult hemophagocytic syndrome (HPS).Methods:A total of 172 adult HPS patients diagnosed in 8 medical centers from January 2013 to August 2020 were selected for the study, of whom 87 were male (50.6%, 87/172), and 85 were female (49.4%, 85/172), with 68 survivors and 104 deaths. The clinical data were summarized, and variables such as lymphocyte subsets, immunoglobulin characteristics and fibrinogen were retrospectively analyzed, and the correlation between the mentioned variables and patient prognosis was analyzed. The optimal cut-off values of continuous variables were calculated by MaxStat, and the prognostic factors of HPS patients were screened based on the Cox proportional hazard regression model.Results:The median age of HPS patients was 56 (42, 66) years old, and the 5-year cumulative survival rate was 37.4% (37.4/100). The median age, platelet and albumin were 48 (27, 63) years, 84×10 9/L and 32.3 g/L in the survival group, and 59 years, 45.5×10 9/L, and 27.3 g/L in the death group, respectively. The differences between the two groups was statistically significant ( Z=?3.368, P=0.001; Z=?3.156, P=0.002; Z=?3.431, P=0.001). Patients with differentiated cluster 8+(CD8+)<11.1%, CD3+<64.9%, CD4+>51%, and CD4/CD8 ratio>2.18 had poor prognosis (χ 2=7.498, P=0.023; χ 2=4.169, P=0.041; χ 2=4.316, P=0.038; χ 2=9.372, P=0.002). Multivariable analysis showed that CD4/CD8 ratio, age, fibrinogen and hemoglobin were independent prognostic factors in HPS patients ( HR=2.435, P=0.027; HR=5.790, P<0.001; HR=0.432, P=0.018; HR=0.427, P=0.018). Conclusion:Peripheral blood lymphocyte subsets can be used to evaluate the prognosis of patients with HPS; CD4/CD8 ratio, age, fibrinogen, and hemoglobin are independent prognostic factors in HPS patients.

Objective To investigate the quality of life of patients with hypertensive disorder complicating pregnancy, analyze the possible influencing factors, and propose corresponding intervention measures. Methods From October 2017 to February 2018, one hundred patients with gestational hypertension were included in the obstetric wards as subjects. Semi-structure interviews were used to evaluate the quality of life and influencing factors. Results Among the quality of life of patients with hypertensive disorder complicating pregnancy, The scores of physiological function (RP), general health (GH), emotional function (RE) and mental health (MH) were lower than the norm, which were (22.45 ± 32.01), (59.40 ± 19.28), (37.07 ± 38.55). ), (65.63 ± 19.72) points, the norm scores were (57.00 ± 19.35), (64.09 ± 14.08), (65.78 ± 22.35), (70.04 ± 16.25) points, and the difference between the two groups was statistically significant (t=-10.687--2.212, both P<0.05 or 0.01). Univariate analysis found that the differences in physical health scores between patients with different places of residence and whether they had received assisted reproductive technology were statistically significant (F=6.860, t=-2.112, P<0.01 or 0.05). The differences in mental health scores between pregnant women, gestational weeks, place of residence, and whether they had received assisted reproductive patients were statistically significant (F=-4.798-3.463,P<0.05 or 0.01). Multiple linear regression analysis found that the place of residence was an independent influencing factor of patients' physiological health (P=0.003), and whether or not assisted reproductive technology was an independent influencing factor of patients′ mental health (P=0.005). Conclusion The quality of life of patients with hypertensive disorders during pregnancy is poor, and appropriate interventions should be actively taken to improve the quality of life of patients.

Objective: To search new prognosis-related genes in gastric cancer by analyzing the high-throughput sequencing data of gastric cancer in TCGA database, and then provide data support for future studies. Methods: The RNA-seq expression matrix data and patient-related clinical data from 375 gastric cancer tissues and 45 adjacent noncancerous tissues were downloaded from the TCGA database. The data were collated and standardized based on the R language. The difference of gene expression was analyzed by the edgeR and DEseq software packages. The survival analysis of obtained differential genes was performed by the univariate and multivariate COX regressions combined with clinical data of patients, and then the genes with clinical significance were screened out. Results: A total of 364 differential genes were obtained by the edgeR and DEseq analysis. Subsequently, the functional enrichment analysis found that these genes were mainly involved in protein digestion and absorption, cytochrome P450 system of drug and exogenous substance metabolism, chemical carcinogenesis, gastric acid secretion and so on. The univariate COX regression analysis showed that FAP, FAT3, PDK4 and ZNF365 genes had significant influences on the prognosis of gastric cancer patients. The multivariate COX stepwise regression analysis showed that the risk model constructed by FAP and PDK4 could predict the prognosis of gastric cancer patients. Conclusion: FAP, FAT3, PDK4 and ZNF365 genes may be the prognostic markers of gastric cancer, which may provide data supports for future clinical and basic studies.
