Diet management is the key part in the prevention and treatment of chronic kidney disease (CKD). A plant-based diet is a diet consisting mostly or entirely of foods derived from plants, with little or no animal foods. In recent years, research on plant-based diets for chronic kidney disease has been increasing. Large-scale epidemiological studies and interventional studies consistently suggest that plant-based diets could reduce the risk of CKD and related complications and slow down CKD progression. This article reviews the research progress of plant-based diets in the prevention and control of CKD.

Objective:To explore the differences of immune reconstitution between peripheral blood stem cell transplantation and umbilical cord blood transplantation.Methods:A total of 300 patients (aged 18 (8, 33), 163 males and 137 females) with malignant hematological diseases who received allogeneic hematopoietic stem cell transplantation in the First Affiliated Hospital of University of Science and Technology of China from January 2018 to March 2020 were enrolled in this study, including 255 cases of umbilical cord blood transplantation and 45 cases of peripheral blood stem cell transplantation. Multicolor flow cytometry was applied to analyze lymphocyte subsets of the percentages and absolute counts in the two donor types and peripheral blood of patients after receiving hematopoietic stem cell transplantation. The differences between the two grafts were compared, and the lymphocyte subsets results were evaluated at 1, 2, 3, 4, 6, 9, 12, and 18 months after transplantation. 18-month disease-free survival (DFS) within the 300 patients under the two transplantation types were retrospectively analyzed.Results:1. The proportion of NKT cells in peripheral blood group was significantly higher than that in cord blood group (2.79% vs 0.24%, P<0.001). 2. The proportion of helper T cells in the UCBT group was higher than that in the PBSCT group, as well as the counts 6 months after transplantation ( P<0.05). 3. The proportion of NK1 cells (3 rd to 9 th month) and count (4 th to 12 th month) in UCBT group were significantly higher than those in PBSCT group ( P<0.05). 4. NKT cells in the UCBT group were lower than those in the PBSCT group (proportion and count) throughout the monitoring process ( P≤0.001). 5. The proportion of DNT cells (within 1 year) and count (within 6 months) in the UCBT group were significantly lower than those in the PBSCT group ( P<0.05). Conclusions:Compared with the peripheral blood stem cell transplantation group, the umbilical cord blood transplantation patients had a faster rate of lymphocyte reconstitution, and patients received umbilical cord blood transplantation had a stronger ability of immune reconstitution and could achieve long-term hematopoiesis.

Overweight and obesity are main risk factors for chronic metabolic diseases, and are strongly associated with the increased risk of premature death. Low carbohydrate diet (LCD) has been proven to effectively control body weight and fat mass in overweight and obese patients by short-term (≤6 months) dietary intervention studies. The mechanisms include regulation of energy metabolism, anti-inflammatory, antioxidant, alteration in expression of lipid metabolic-related genes and modulation of intestinal flora. However, the conclusions are inconsistent on whether LCD can cause durable weight loss and reduce the risk of overweight and obesity. This review summarizes the current research progress on the mechanisms, epidemiological studies, intervention studies and potential risks of LCD in controlling overweight and obesity, providing a reference for the future research and clinical application.

Objective To explore the effect of tea polyphenols on the growth of human papillomavirus 16 (HPV16) subgenes-immortalized human cervical epithelial cells (H8 cells).Methods Cultured H8 cells were divided into 5 groups to be treated with 0 (control group),6.25,12.5,25 and 50 mg/L tea polyphenols respectively for 24,36,and 48 hours,and then cell counting kit-8 (CCK8)assay was performed to detect cell proliferation.After 24 hours of incubation,flow cytometry was conducted to detect cell apoptosis and cell cycle,and fluorescence microscopy to observe the morphology of apoptotic cells.Results After incubation with tea polyphenols at different concentrations for 24,36 and 48 hours,the proliferation of H8 cells was inhibited,and 12.5 mg/L tea polyphenols could inhibit the relative growth rate of H8 cells in a time-dependent manner.Flow cytometry showed that there was a significant difference in cell apoptosis rate among the 6.25-,12.5-,25-,50-mg/L tea polyphenols groups and the control group (52.62％ ± 0.62％,52.22％ ± 0.72％,42.52％ ± 0.90％,45.96％ ± 2.11％,29.96％ ± 0.70％ respectively,F =272.0,P ＜ 0.05).Moreover,all the tea polyphenol groups showed significantly increased cell apoptosis rate compared with the control group (all P ＜ 0.05).Fluorescence microscopy showed karyopyknosis,nuclear fragmentation and other typical apoptotic morphological changes in H8 cells in tea polyphenols groups.There were significant differences in the percentage of cells in G1,G2 phase and cell proliferation index among the 5 groups (all P ＜ 0.05).Compared with the control group,the 6.25-,12.5-,25-mg/L tea polyphenols groups showed significantly increased percentage of cells in G1 phase (55.96％ ± 0.72％,54.12％ ± 3.20％,65.30％ ± 1.51％ respectively,all P ＜ 0.05),but significantly decreased percentage of cells in G2 phase (3.17 ± 1.82％,4.94 ± 1.46％,4.65 ± 4.26％ respectively,all P ＜ 0.05) and lower cell proliferation index(0.44 ± 0.01,0.46 ± 0.02,0.36 ± 0.01 respectively,all P ＜ 0.05).Conclusion Tea polyphenols can inhibit the proliferation of H8 cells,induce cell apoptosis,and block cell cycle progression.

PURPOSE: Breast cancer is the most commonly occurring cancer among women worldwide, and therefore, improved approaches for its early detection are urgently needed. As microRNAs (miRNAs) are increasingly recognized as critical regulators in tumorigenesis and possess excellent stability in plasma, this study focused on using miRNAs to develop a method for identifying noninvasive biomarkers. METHODS: To discover critical candidates, differential expression analysis was performed on tissue-originated miRNA profiles of 409 early breast cancer patients and 87 healthy controls from The Cancer Genome Atlas database. We selected candidates from the differentially expressed miRNAs and then evaluated every possible molecular signature formed by the candidates. The best signature was validated in independent serum samples from 113 early breast cancer patients and 47 healthy controls using reverse transcription quantitative real-time polymerase chain reaction. RESULTS: The miRNA candidates in our method were revealed to be associated with breast cancer according to previous studies and showed potential as useful biomarkers. When validated in independent serum samples, the area under curve of the final miRNA signature (miR-21-3p, miR-21-5p, and miR-99a-5p) was 0.895. Diagnostic sensitivity and specificity were 97.9% and 73.5%, respectively. CONCLUSION: The present study established a novel and effective method to identify biomarkers for early breast cancer. And the method, is also suitable for other cancer types. Furthermore, a combination of three miRNAs was identified as a prospective biomarker for breast cancer early detection.

Objective:To study the antitumor mechanism of W40,a monomer purified from Wedelia prostrate (Hook.et Arn.) Hemsl.Methods:The effects of W40 on the cell proliferative of GLC-82 cells were detected by MTT assay and colony formation assay.The migratory abilities of GLC-82 cells were observed by wound healing assay.Cell apoptosis was evaluated by Annexin V-FITC/PI staining analysis.The levels of apoptosis-relative proteins and cell proliferation-related proteins,such as Caspase-3,PARP,Stat3 and ERK,were detected by Western blotting.Results:MTF assay showed that W40 had a significant cytotoxic effect on non-small cell lung cancer GLC-82 cells.Colony formation assays showed that W40 significantly inhibited GLC-82 cells proliferation.The migration of GLC-82 cells was inhibited by W40 in a dose-dependent manner.Flow cytometry showed that the apoptotic rate increased gradually in a concentration-dependent manner.W40 down-regulated Stat3 as decreasing p-Stat3 and downstream proteins of Bcl-2 and Mcl-1.At the same time,W40 up-regulated the expression of pro-apoptotic protein Bax,and increased the cleavaged Caspase-9,Caspase-3 and PARP.W40 also down-regulated BRAF / MAPK / ERK signal pathway as decreasing p-BRAF,p-MEK and p-ERK.Conclusions:W40 induced apoptosis by inhibiting BRAF / MAPK / ERK and Stat3 signaling pathways.

Objective To investigate the knowledge,attitude and practice (KAP) status quo of the primary caregivers on cardiopulmonary resuscitation (CPR) in the patients with high risk of sudden cardiac death (SCD).Methods The convenience sampling method was used to extract 139 primary caregivers of the inpatients with high risk of SCD in the cardiology department of our hospital from January to June 2015.The self-designed questionnaire was adopted to perform the KAP status quo investigation on CPR and the influence factors were analyzed.Results The scoring rate of knowledge,attitude and practice about CPR in the primary caregivers were 36.85%,64.26% and 29.24%,respectively;the cultural level,residence place,health status,training experience,first-aid experience and sick time of the patients were the influence factors of KAP on CPR (P<0.05).Conclusion The KAP status quo of CPR among primary caregivers are poor.It is necessary to strengthen CPR training in primary caregivers and improve their KAP level.

Background:In patients with diffuse large B?cell lymphoma (DLBCL), central nervous system (CNS) relapse is uncom?mon but is nearly always fatal. This study aimed to determine the risk factors for CNS relapse in DLBCL patients and to evaluate the effcacy of rituximab and intrathecal chemotherapy prophylaxis for CNS relapse reduction. Methods:A total of 511 patients with newly diagnosed DLBCL treated at the Sun Yat?sen University Cancer Center between January 2003 and December 2012 were included in the study. Among these patients, 376 received R?CHOP regimen (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) as primary treatment, and 135 received CHOP regimen (cyclophosphamide, doxorubicin, vincristine, and prednisone) as primary treatment. Intrathe?cal chemotherapy prophylaxis (methotrexate plus cytarabine) was administered to those who were deemed at high risk for CNS relapse. In the entire cohort and in the R?CHOP set in particular, the Kaplan–Meier method coupled with the log?rank test was used for univariate analysis, and the Cox proportional hazards model was used for multivariate analysis. Differences were evaluated using a two?tailed test, andP<0.05 was considered signiifcant. Results:At a median follow?up of 46months, 25 (4.9%) patients experienced CNS relapse. There was a trend of reduced occurrence of CNS relapse in patients treated with rituximab; the 3?year cumulative CNS relapse rates were 7.1% in CHOP group and 2.7% in R?CHOP group (P=0.045). Intrathecal chemotherapy prophylaxis did not confer much beneift in terms of preventing CNS relapse. Bone involvement [hazard ratio (HR)=4.21, 95% conifdence interval (CI) 1.38–12.77], renal involvement (HR=3.85, 95% CI 1.05–14.19), alkaline phosphatase (ALP) >110U/L (HR=3.59, 95% CI 1.25–10.34), serum albumin (ALB) <35g/L (HR=3.63, 95% CI 1.25–10.51), treatment with rituxi?mab (HR=0.34, 95% CI 0.12–0.96), and a time to complete remission≤ 108days (HR=0.22, 95% CI 0.06–0.78) were independent predictive factors for CNS relapse in the entire cohort. Bone involvement (HR=4.44, 95% CI 1.08–18.35), bone marrow involvement (HR=11.70, 95% CI 2.24–60.99), and renal involvement (HR=10.83, 95% CI 2.27–51.65) were independent risk factors for CNS relapse in the R?CHOP set. Conclusions:In the present study, rituximab decreased the CNS relapse rate of DLBCL, whereas intrathecal chemo?therapy prophylaxis alone was not suffcient for preventing CNS relapse. Serum levels of ALB and ALP, and the time to complete remission were new independent predictive factors for CNS relapse in the patients with DLBCL. In the patients received R?CHOP regimen, a trend of increased CNS relapse was found to be associated with extranodal lesions.
