Objective:To investigate the clinical value of peripheral blood T lymphocytes in the diagnosis and prognosis of patients with hepatocellular carcinoma (HCC) recurrence after liver transplantation.Methods:The clinical and laboratory data of 50 HCC patients, who received liver transplantation and were followed up in the Liver transplantation Center of Beijing Youan Hospital from January 2014 to December 2016, were retrospectively analyzed. The differences on clinical laboratory indicators and five-year survival were compared between HCC recurrence group ( n=29) and non-recurrence group ( n=21). Spearman correlate analysis was used to analyze the correlation between clinical laboratory indicators and HCC recurrence after liver transplantation. Receiver operator characteristic (ROC) curve was used to analyze the diagnostic value of CD4+T lymphocytes in HCC recurrence after liver transplantation. Kaplan-Meier survival curve was used to compare the survival time of patients with different CD4+T lymphocytes levels post liver transplantation. Results:Compared to non-recurrence group, the level of alanine aminotransferase, aspartate aminotransferase, γ-glutamyltransferase, albumin, lymphocytes, alpha-fetoprotein, protein induced by vitamin K deficiency or antagonist-Ⅱ, CD3+, CD4+and CD8+T lymphocytes were significantly different (all P<0.05). The median recurrence time after liver transplantation was 13.0 (6.0, 24.0) months, and the mortality rate was 100%. The 5-year mortality rate was 0 in the non-recurrence group. During 5-year follow-up, the median survival time of patients in the HCC recurrence group was 18.0 (9.0, 36.0) months, which was significantly lower than that of non-recurrence group [60.0 (60.0, 60.0) months, ( P<0.05)]. Compared with non-recurrence group, the CD3+, CD4+, and CD8+T lymphocytes were significantly lower in the recurrence group (all P<0.05). Spearman correlate analysis showed that HCC recurrence after liver transplantation was negatively correlated with the CD3+, CD8+and CD4+T lymphocytes ( r=-0.43, -0.38, -0.44, all P<0.05). ROC analysis showed that CD4+T lymphocytes at cutoff of≤265.50 cells/μl was valuable for the diagnosis of HCC recurrence after liver transplantation (specificity 100%, sensitivity 48.30%). Survival curve analysis showed that the survival time was significantly lower in the CD4≤265.50 cells/μl group [15.0 (10.0, 36.8) months] than that in the CD4>265.50 cells/μl group [53.0 (19.5, 60.0) months] ( P<0.05). Conclusion:There is a significant negative correlation between CD4+T lymphocytes and HCC recurrence after liver transplantation. CD4+T lymphocytes at cutoff value of≤265.50 cells/μl is valuable for the clinical diagnosis and prognosis evaluation of HCC recurrence after liver transplantation.

Objective:To explore the effects of occupational and recreational therapy on symptom distress and mental toughness in perioperative period for lung neoplasms patients.Methods:By adopt convenient sampling method, a total of 92 cases of lung tumor patients were collected the lung cancer department in Tianjin Medical University Cancer Institute & Hospital from December 2019 to September 2020 in pulmonary oncology department.

Objective:To explore the status quo and influencing factors of spiritual health in children with acute leukemia during treatment.Methods:The children with leukemia admitted in the First Affiliated Hospital of Zhengzhou University from August 2018 to April 2019 were selected. The general data questionnaire and Functional Assessment of Chronic Illness Therapy-Spiritual-12 (FACIT-Sp-12) were used to investigate the status quo of their spiritual health and analyze its influencing factors. A total of 150 questionnaires were distributed and 147 valid questionnaires were recovered, with an effective recovery rate of 98%.Results:The total score of spiritual health among 147 children with acute leukemia was (25.21±6.62) , including (10.17±3.92) for belief, (8.72±2.58) for meaning, and (9.39±3.28) for peace. There were statistically significance differences in spiritual health scores between children with different age, disease type and educational background of their guardians ( P<0.05) . Multiple linear regression analysis showed that age, type of disease, and education background of the guardian were factors affecting the spiritual health level of children with leukemia ( P<0.05) . Conclusions:The spiritual health of children with acute leukemia is at a medium level, which is related to the age, type of disease and educational background of the guardian. Medical staff should provide spiritual care to children with leukemia and improve the quality of life of children.

The incidence of lung cancer in China ranks first and second among men and women respectively .Meanwhile, lung cancer is also the leading cause of death in malignant tumors in China .Surgical treatment is of great significance in impro-ving the prognosis of patients with lung cancer, and the number of related clinical trials is increasing year by year.Through a retrospective review of clinical trials in the field of lung cancer and thoracic surgery on the Clinicaltrials .gov platform, this arti-cle finds that relevant clinical trials focus on treatment , perioperative management and basic research.Although the clinical tri-als in China started late, they have developed rapidly and the number of clinical trials ranked second.In addition, there are some shortcomings in the clinical trials of China in terms of trial design and research scope , and there is still a gap between Chinese and foreign trials.

Objective:To investigate the use of proton pump inhibitors (PPIs)in gynecological patients in a hospital and analyze the use rationality of PPIs for the prevention of stress ulcer so as to provide reference for the clinical application of PPIs. Methods:To-tally 1000 patients' medical records admitted to the gynecological department for the first time from January 1st to December 31st in 2016 were randomly selected to conduct a retrospective analysis,and the rationality of PPIs was evaluated. Results:The preventive use rate of PPIs was 90.72%(880/970). Among the 880 patients, 28.18%(248/880) of the patients were without indications for the preventive medication,95.68%(842/880) of the patients were with wrong administration time, and 91.46%(578/632) of the pa-tients were with wrong usage and dosage. Conclusion:When PPIs are used for the prevention of SU in gynecological surgery,irrational use such as without indications, unsuitable variety selection and wrong usage and dosage still exists. It is suggested that regulators should strengthen technical and administrative interventions and establish standard for the rational use of PPIs in hospitals so as to avoid the excessive use of PPIs and improve the situation of inappropriate application.

China still has more than 30,000 patients of advanced schistosomiasis while new cases being reported consistently. D-dimer is a fibrin degradation product. As ascites being the dominating symptom in advanced schistosomiasis, the present study aimed to explore a prediction model of ascites with D-dimer and other clinical easy-achievable indicators. A case-control study nested in a prospective cohort was conducted in schistosomiasis-endemic area of southern China. A total of 291 patients of advanced schistosomiasis were first investigated in 2013 and further followed in 2014. Information on clinical history, physical examination, and abdominal ultrasonography, including the symptom of ascites was repeatedly collected. Result showed 44 patients having ascites. Most of the patients' ascites were confined in the kidney area with median area of 20 mm². The level of plasma D-dimer and pertinent liver function indicators were measured at the initial investigation in 2013. Compared with those without ascites, cases with ascites had significantly higher levels of D-dimer (0.71±2.44 μg/L vs 0.48±2.12 μg/L, P=0.005), as well ALB (44.5 vs 46.2, g/L) and Type IV collagen (50.04 vs 44.50 μg/L). Receiver operating characteristic curve analyses indicated a moderate predictive value of D-dimer by its own area under curve (AUC) of 0.64 (95% CI: 0.54–0.73) and the cutoff value as 0.81 μg/L. Dichotomized by the cutoff level, D-dimer along with other categorical variables generated a prediction model with AUC of 0.76 (95% CI: 0.68–0.89). Risks of patients with specific characteristics in the prediction model were summarized. Our study suggests that the plasma D-dimer level is a reliable predictor for incident ascites in advanced schistosomiasis japonica patients.
